AHA/ASA Releases Updated Secondary Stroke Prevention Guidelines

News Author: Pauline Anderson
CME Author: Charles P. Vega, MD
CME/CE Released: 10/25/2010; Valid for credit through 10/25/2011

October 25, 2010 — New recommendations on metabolic syndrome treatment and acknowledgement of a place for stenting in the management of symptomatic carotid stenosis are among the changes seen in updated secondary stroke prevention guidelines from the American Heart Association (AHA)/American Stroke Association (ASA).
The new guidelines were published online October 21 in Stroke. The document notes that the American Academy of Neurology "affirms the value" of the guideline as an educational tool for neurologists and that it has been reviewed and the content affirmed by the American Association of Neurological Surgeons and the Congress of Neurological Surgeons.
The aim of the statement is to provide comprehensive and timely evidence-based recommendations on the prevention of ischemic stroke among survivors of ischemic stroke or transient ischemic attack, the authors write.
This and other AHA stroke-related statements are updated on a regular basis, with these secondary stroke prevention guidelines last being updated in 2006, said Robert J. Adams, MD, professor of neuroscience at the Medical University of South Carolina, Charleston, and a member of the review committee.
"We make a continual effort to get the best recommendations we can looking at the evidence, and as you'll see in some areas, we felt that we couldn't really make a recommendation because we felt we didn't have enough data," Dr. Adams told Medscape Medical News. "Those are basically by default or de facto areas where we think more research is needed."
This update is also among the first to flag new recommendations within the text of the document, said Dr. Adams. "We decided to point out to the reader what was new."
New Metabolic Syndrome Recommendations
All 3 recommendations pertaining to metabolic syndrome are new. The syndrome is a confluence of several physiological abnormalities that increase the risk for vascular disease. According to AHA/ASA criteria, metabolic syndrome is recognized when 3 of the following features are present:
  • increased waist circumference (≥102 cm in men; ≥88 cm in women),
  • elevated triglyceride levels (≥150 mg/dL),
  • reduced high-density lipoprotein cholesterol (<40 mg/dL in women; <50 mg/dL in men),
  • elevated blood pressure (systolic ≥130 mm Hg, or diastolic ≥ 85 mm Hg), and
  • elevated fasting glucose (≥100 mg/dL).
To prevent a secondary stroke or transient ischemic attack in patients who have metabolic syndrome, clinicians should treat the individual components of the syndrome that are also stroke risk factors, particularly dyslipidemia and hypertension, the new guidelines note.
Management of patients with metabolic syndrome should include counseling on diet, exercise, and weight loss to reduce vascular risks, but the utility of screening patients for metabolic syndrome after stroke has not been established.
There is considerable controversy surrounding this syndrome, largely because of uncertainty regarding its etiology and clinical usefulness, the authors write. The disorder has been related to an increased risk for diabetes, cardiovascular disease, and all-cause mortality.
The association between metabolic syndrome and risk for first ischemic stroke has been examined in several recent studies, with all except 1 confirming the association, but with only 1 study examining the association between metabolic syndrome and risk for stroke recurrence.
In the Warfarin Aspirin Symptomatic Intracranial Disease (WASID) trial, participants with metabolic syndrome were more likely to have a stroke, myocardial infarction, or vascular death during 1.8 years of follow-up than participants without metabolic syndrome (hazard ratio [HR], 1.6; 95% confidence interval [CI], 1.1 - 2.4; P = .0097). Patients with the syndrome were also at increased risk for ischemic stroke alone (HR, 1.7; 95% CI, 1.1 - 2.6; P = .012).
Cardiac features of metabolic syndrome improve with weight loss, which has also been shown to improve insulin sensitivity, lower plasma glucose, low plasma low-density lipoprotein cholesterol, lower plasma triglycerides, raise high-density lipoprotein cholesterol, lower blood pressure, reduce inflammation improve fibrinolysis, and improve endothelial function in patients with metabolic syndrome.
Carotid Artery Stenting
Also included in the revised guidelines is updated research pertaining to carotid artery stenting for extracranial symptomatic carotid disease, based on results of large clinical trials, including the Carotid Revascularization Endarterectomy vs Stent Trial (CREST), most recently reported.
Carotid endarterectomy is recommended for these symptomatic patients with high-grade stenosis (70% - 99%) if the perioperative morbidity and mortality risk is estimated at less than 6%, as well as for those with moderate stenosis (50% - 99%); neither stenting nor surgery is recommended for stenoses less than 50%.
However, the writing group notes that carotid artery stenting is indicated as an alternative to surgery for symptomatic patients at average or low risk for complications associated with endovascular intervention when the diameter of the lumen of the internal carotid artery is reduced by more than 70% by noninvasive imaging or more than 50% by catheter angiography.
"The recommendation is that for certain patients with symptomatic high-grade carotid stenosis and factors that make carotid endarterectomy not favorable, such as previous radiation therapy or previous surgery, or certain medical conditions which increase risk for surgery, that carotid artery stenting is a reasonable alternative," commented Dr. Adams.
Stenting in that setting is "reasonable when performed by operators with established periprocedural morbidity and mortality rates of 4% to 6%," the authors add — rates similar to those seen in stenting and surgery trials.
Finally, a new recommendation is that all of these patients receive optimal medical therapy, including antiplatelet therapy, statins, and a risk factor modification.
Atrial Fibrillation
New recommendations on the management of atrial fibrillation (AF) are based on data from the Atrial Fibrillation Clopidogrel Trial with Irbesartan for Prevention of Vascular Events (ACTIVE) study and ACTIVE A, an arm of the study that compared aspirin with clopidogrel plus aspirin in patients with AF who were considered unsuitable for vitamin K antagonist therapy.
Patients were considered "unsuitable" for warfarin based on physician judgment or patient preference — criteria that were somewhat controversial when this study was first presented. Trial results showed less stroke but more bleeding with clopidogrel plus aspirin vs aspirin alone.
In the new guidelines, however, authors write that "on the basis of uncertainty of how to identify patients who are 'unsuitable' for anticoagulation, as well as the lack of benefit in the analysis of vascular events plus major hemorrhage, aspirin remains the treatment of choice for AF patients who have a clear contraindication to vitamin K antagonist therapy but are able to tolerate antiplatelet therapy."
The combination of clopidogrel plus aspirin carries a bleeding risk similar to warfarin and so is not recommended for those with a hemorrhagic contraindication to warfarin, the authors note.
Another new recommendation is that for patients with AF who are at high risk for recurrent stroke, but who require temporary interruption of oral anticoagulation, bridging therapy with a low-molecular-weight heparin is reasonable, said Dr. Adams.
These new AF guidelines were written before regulatory approval of the oral thrombin inhibitor dabigatran, based on encouraging results in the previously reported Randomized Evaluation of Long-Term Anticoagulation Therapy (RE-LY) study.
"No recommendation will be provided for dabigatran in the current version of these guidelines because regulatory evaluation and approval has not yet occurred," the authors note in the document. "However, the availability of a highly effective oral agent without significant drug or food interactions that does not require coagulation monitoring would represent a major advance for this patient population."
They also discuss the WATCHMAN left atrial appendage occlusion device, studied in the Embolic Protection in Patients with Atrial Fibrillation (PROTECT-AF) trial as an alternative to oral anticoagulants. "This approach is likely to have the greatest clinical utility for AF patients at high stroke risk who are poor candidates for oral anticoagulation; however, more data are required in these populations before a recommendation can be made."
Intracranial Atherosclerosis
There is also new research in the area of intracranial atherosclerosis. "There is some new information on the use of antiplatelet agents; it actually didn't substantially change the guidelines, but it makes the choice somewhat easier, and provides additional information that we didn't have before," said Dr. Adams.
The new information was from the WASID trial, on which the recommendation for aspirin over warfarin is based. Aspirin doses of 50 to 325 mg/day are recommended, the authors write. Intracranial stenting is considered investigational at this time, and its utility is still unknown, they note.
As well, there is a new recommendation concerning maintenance of blood pressure, suggesting that for patients with stroke or transient ischemic attack caused by 50% to 99% stenosis of a major intracranial artery, long-term maintenance of blood pressure lower than 140/90 mm Hg and total cholesterol level lower than 200 mg/dL may be reasonable, and there is also a new recommendation against bypass surgery in these patients.
Conflict of Interest Scrutiny
Finally, another new element to these guidelines was the "scrutiny" of committee members reviewing the literature to minimize conflicts of interest, said Dr. Adams.
"How that was managed this time was that we were all given assignments in areas that were unrelated to anything we put on the conflict of interest form;" the upshot is that he was reviewing research, "that I have no interest in or ever spoken about."
All members of the writing group were required to complete and submit a disclosure questionnaire showing all such relationships that might be perceived as real or potential conflicts of interest.

How Are You Choosing a Specialty?


Joshua Batt, Medical Student, 05:32PM Nov 20, 2010

he cut was made, some dissection performed and the baby was pulled out. I was holding our patient's uterus in one hand and assisting my attending with the other during a scheduled cesarean section. All I could think was how this doctor's job is simply amazing. How many people can say that they get to open a person's body, pull out a living organism and twelve inches away, you can stare the patient in the face and have a discussion with them?

Between the work of the anesthesiologist and the obstetrician, I was enthralled by the situation. Their team effort and training made the operation a success. Baby was beautiful, mom and dad were happy and the medical crew had performed well. It was not a long procedure, but one that left me wondering if I could be doing this as a career. Yet another moment of reflection needed if I am ever going to decide what to be "when I grow up."
That question, "What are you going to be when you grow up?" continues to haunt me as time rushes past. At least I have the doctor part down; now to narrow things down a little. It certainly doesn't help going into residency applications and interviews with multiple fields of interest and no geographical preference. There are simply too many places, professions, and programs to choose from.
Some aids I have found include the specialty flowchart, the University of Virginia's Medical Specialty Aptitude Test (MSAT), and The Ultimate Guide to Choosing a Medical Specialty. There are days when I agree with their advice and other days I think they are in left field. What have you found useful in making your decision?

Women Who Suffer Migraine With Aura Have Better Outcomes After Stroke

Article Date: 01 Dec 2010 - 2:00 PST

Women with a history of migraine headache with aura (transient neurological symptoms, mostly visual impairments) are at increased risk of stroke. However, according to new research reported in Circulation: Journal of the American Heart Association stroke events in women with migraine with aura are more likely to have mild or no disability compared to those without migraine.

In a new analysis of the Women's Health Study involving 27,852 women over 13.5 years, researchers found those who have migraine with aura and who experience an ischemic stroke were twice as likely to have no significant disability from stroke.

"The message from this study should be reassuring for migraineurs," said Tobias Kurth, M.D., Sc.D., the study's principal author and associate epidemiologist at Brigham and Women's Hospital in Boston, Mass.

"It is important for women who have migraine with aura to know that their risk of stroke is considerably low and there is high likelihood of a migraine-associated stroke being mild."

The reason for these results is unclear. But Kurth, who is also director of research at INSERM in Paris, France, speculated that mechanisms, perhaps involving smaller vessels - not the traditional mechanisms for stroke, lead to a smaller size stroke.

Compared to those without migraine history, women with migraine and aura were more likely to have a good to excellent functional outcome - defined as having no symptoms and no significant disability, researchers said.

Women participating in the study were divided into four groups: 22,723 who reported no migraine history; 5,129 who reported a migraine history; 3,612 who had active migraine; and of those who reported active migraine, 1,435 reported active migraine with aura.

Researchers evaluated functional ability after stroke at hospital discharge using the modified Rankin Scale, a seven-point scale that measures degree of impairment.

At the onset of the study, women completed a questionnaire about their headaches that allowed classification into the groups of migraine with and without aura, history of migraine or no history of migraine. Each following year, the women reported new medical conditions, including transient ischemic attack (TIA) or stroke, which were confirmed after medical record review.

During 13.5 years of follow-up, 398 TIAs and 345 ischemic strokes occurred.

Women in the study were primarily Caucasian, average age 55, healthy and working in the healthcare field.

There is currently little reason to believe that the association differs for women with other characteristics or men, Kurth said.

The first author is Pamela M. Rist, M.Sc., a doctoral student at the Harvard School of Public Health and research fellow at Brigham and Women's Hospital. Other co-authors are: Julie E. Buring, Sc.D.; Carlos S. Kase, M.D.; Markus Schurks, M.D., M.Sc. Author disclosures are on the manuscript.

The Women's Health Study is supported by grants from the National Heart, Lung, and Blood Institute and the National Cancer Institute. Grants from the Donald W. Reynolds, Leducq and Doris Duke Charitable foundations funded part of the study.

Protein in the Urine: A Warning Sign for Cognitive Decline

 Released: 11/10/2010 3:00 PM EST
Embargo expired: 11/20/2010 9:15 PM EST

1. Small Amounts of Urinary Protein Predict More Rapid Cognitive Decline in Elderly Women
Screening Efforts in Older Individuals May Be Warranted
A new study has found that low amounts of albumin in the urine, at levels not traditionally considered clinically significant, strongly predict faster cognitive decline in older women. The study involved more than 1,200 women aged >70 years in the Nurses' Health Study who were phoned every two years for three cycles and tested for general cognition, verbal/word memory, verbal fluency (speed in making word associations), and working/short-term memory. Julie Lin, MD (Brigham and Women’s Hospital) and her colleagues found that participants with a urinary albumin-to-creatinine ratio of >5 mcg/mg at the start of the study experienced cognitive decline at a rate 2 to 7 times faster in all cognitive measures than that attributed to aging alone over an average 6 years of follow-up. “The strongest association was seen with a decline in the verbal fluency score, which has been attributed to progressive small vessel disease in the brain, which supports the view that albuminuria is an early marker of diffuse vascular disease,” said Dr. Lin. “Therefore, in light of the aging U.S. population, which is at risk for cognitive decline and vascular disease, simple, non-invasive screening for albumin in the urine as an independent predictor for subsequent cognitive decline may represent an important public health issue.”
Study co-authors include Fran Grodstein, PhD, Jae Hee Kang, PhD, and Gary Curhan, MD, ScD, (Brigham and Women's Hospital).
Disclosures: Dr. Curhan is a consultant for Takeda Pharmaceuticals; receives grants/research support from Astellas and honoraria from Takeda Pharmaceuticals. Dr. Lin, Dr. Grodstein, and Dr. Hee Kang reported no other financial disclosures.
The study abstract, “A Prospective Study of Albuminuria and Cognitive Decline in Women,” [SA-FC355] will be presented as an oral presentation on Saturday, November 20 Day, Date at 5:18 PM MT in Room 405 of the Colorado Convention Center in Denver, CO.
2. Urinary Protein Excretion Increases Risk of Cognitive Impairment
Simple Urine Tests Could Identify Individuals at Risk
Two characteristics of kidney disease—excreting protein in the urine (albuminuria) and low kidney function—increase individuals’ risk of becoming confused and forgetful. To see whether these two characteristics are related or independent in their effects on cognitive decline, Manjula Kurella Tamura, MD (Stanford University) and her colleagues studied clinical data from 19,399 individuals participating in the Renal Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. A total of 1,184 participants (6.1%) developed cognitive impairment over an average follow-up of 3.8 years. Individuals with albuminuria were 1.31-1.57 times more likely to develop cognitive impairment compared to individuals without albuminuria. This association was strongest for individuals with normal kidney function (eGFR ≥60 ml/min/1.73m2) and attenuated among individuals with low levels of kidney function. Conversely, low kidney function (eGFR <60 ml/min/1.73m2) was associated with a higher risk for developing cognitive impairment only among individuals without albuminuria. Surprisingly, individuals with albuminuria and normal kidney function had a higher probability for developing cognitive impairment as compared to individuals with moderate reductions in kidney function (eGFR 45-59 ml/min/1.73m2) in the absence of albuminuria. The findings indicate that the presence of protein in the urine, even in small amounts, could be a warning sign that a patient may later have difficulty thinking clearly. “The results are important because albuminuria is easily measured and potentially modifiable. Incorporating information about albuminuria along with kidney function should help clinicians identify patients at high risk for subsequent cognitive decline and dementia,” said Dr. Kurella Tamura.
Study co-authors include Virginia Wadley, PhD, Mary Cushman, Frederick Unverzagt, PhD, Neil Zakai, MD, Brett Kissela, MD, David Warnock, MD, and William McClellan, MD (for the REGARDS Study Group, University of Alabama at Birmingham).
Disclosures: The study received pharmaceutical company support in addition to funding from the National Institute of Neurological Disorders and Stroke. Dr. Cushman is a consultant for Glaxo Smith Kline and receives grants/research support from Amgen. Dr. Unverzagt holds ownership in Eli Lilly. Dr. Warnock is a consultant for Genzyme and Gilhead, holds ownership in Parion and Relypsa, and receives honoraria from Genzyme, Amicus, Amgen, Gilhead, and Shire. Dr. McClellan receives grant/research support from and is a scientific advisor for Amgen. Dr. Wadley, Dr. Zakai, and Dr. Kissela reported no financial disclosures.
The study abstract, “Albuminuria, Kidney Function and the Incidence of Cognitive Impairment in US Adults,” [SA-FC359] will be presented as an oral presentation on Saturday, November 20 Day, Date at 6:06 PM MT in Room 405 of the Colorado Convention Center in Denver, CO.

'Doctor, Are You Telling Me the Truth?' Exclusive Ethics Survey Results

Shelly M. Reese.
Posted: 11/30/2010.

"Honesty is the best policy" and "the patient always comes first."
As absolute and correct as those aphorisms may be, they can be hard for doctors to apply in the complex world of modern medicine.
A recent Medscape medical ethics survey of over 10,000 physicians found that when it comes to patient treatment, a significant number of physicians struggle when it comes to topics relating to honest, straight-forward communication, and even pain management. Physicians from a broad range of specialties answered 3 questions pertaining to patient treatment:
-     Would you ever hide information from a patient about a terminal or preterminal diagnosis, because you believe that it will bolster their spirit or attitude?
-      Would you ever prescribe a treatment that's a placebo, simply because the patient wanted treatment?
-      Would you ever undertreat a patient's pain, because of a fear of repercussions or because you are concerned that a patient -- even a terminal patient -- might become addicted?

Open Communication Is Often Difficult

When it comes to delivering bad news, 59.8% of physicians indicate they "tell it exactly as I see it," while 14.6% indicate that they soften the news and "give hope even if there is little chance." Two percent indicate that unless a patient is going to die imminently, they don't tell him or her how bad the situation is and nearly one quarter (23.8%) say "it depends."
"The kind of compassion that brings people into medicine is the type of compassion that is needed for delivering bad news," says Kenneth Goodman, PhD, Director of the Bioethics Program at the University of Miami and author of Ethics and Evidence-Based Medicine: Fallibility and Responsibility in Clinical Medicine. But that compassion should never compromise the truth, he cautions.
Many of the physicians surveyed augmented their responses noting that, while they are honest, they try hard to deliver bad news in the most gentle, humane, and supportive way possible. That's exactly what patients should expect from their doctors, Goodman advises. But in "softening" the truth, he believes that doctors don't need to deviate from it.
"If there is something positive you can say, by all means say it. But only tell the truth: 'I will be there with you. I will help you manage your pain. I will see to it that you can arrange your affairs.' Those are truthful things," Goodman says.
When doctors withhold information, they make it more difficult for patients to chart their course and undermine their own credibility.
From the patient's point of view, "If I don't know my time is limited I can't put my affairs in order. I can't say, 'I'm sorry,'" he says. What's more, "it's not like patients are asking Dr. Kildare, 'What are my chances, Doc?' Patients are increasingly educated. If you don't tell them, they're going to be looking it up on the internet the next day, so you should probably be the source of the data, because you're a human and you care about them."


Goodman advises that the same rationale applies to the use of placebos. Nearly one quarter (23.5%) of respondents said they would prescribe a treatment that was essentially a placebo to a patient simply because he or she wanted treatment. Another 18.2% said, "It depends."
Physicians who were willing to provide "placebo" treatment generally fell into 2 camps. Some said they would do it to appease a patient but only after telling them it wouldn't do them any good. One doctor noted that he'd prescribe vitamins and supplements, "but I'd tell them I thought it was worthless"; while another would prescribe a cream for hemorrhoids, "but they are also forewarned" that the treatment wouldn't do any good.
Still another noted, "In this day and age, many patients will not accept that the best treatment is tincture of time and they have no hesitation about reporting you to the state board or hospital administrator. So, I figure out something that will do the least potential harm and try that."
Others say they'd be willing to prescribe a benign but ineffectual treatment in hopes of achieving a positive placebo effect. "Placebo works up to 50% of the time," said one. "Placebos ARE a form of treatment!" noted another and, "Placebo can be psychologically beneficial and I don't see that as placebo," wrote a third.
Physicians in the first group need to be able to stand their ground in the face of insistent patients, Goodman advises. After all, they are the medical experts.
"Doctors need to be able to say, 'I'm sorry, there is nothing I can do,' No physician is going to provide drugs for a recreational purpose. Why, if a patient asks for an antibiotic for a virus or a prescription that won't work, should he get it?" Goodman asks. As for those hoping to achieve a placebo effect he notes, if a patient finds out he or she has been prescribed a placebo, it will cause irrevocable damage to the physician-patient relationship.

Pain Management Quandaries

While the first 2 patient treatment questions in the survey pertained to communication, the last addressed pain management. While the overwhelming majority (84.1%) of physicians said they would never undertreat pain, a handful (5.6%) said they would, and about 1 in 10 (10.3%) said they would have to evaluate the situation before making a decision.
After filtering out responses from physicians – many of them emergency department doctors – noting that they routinely deny drug-seeking "frequent fliers" prescriptions for pharmaceuticals, the theme frequently voiced by doctors was that they would undertreat pain due to fear of lawsuits. A number of respondents augmented their answers with frustrated, emotional responses about state medical boards, government intrusion, and litigious patients.
Comments included: "I undertreat not due to concerns about addiction but concerns about Drug Enforcement." "We live in a real world. I would like to think I would answer 'no' if real tort reform took place." "I bet we all would in today's drug-abusing, litigious society." And "The state boards can wreck a doctor without appeal."
Despite those concerns, others remained steadfast. "I have only the patient to believe as to how much pain they are experiencing. I have been lied to at times over the years, but I would rather try to believe people than to deny everyone because of some bad actors," wrote one.

When Treatment Denial Causes Suffering

Another noted that physicians' fears of repercussions have "caused patients to suffer needless pain. If a physician does not feel competent or comfortable handling pain issues, (s)he should refer that patient to a reputable pain specialist. Pain is a legitimate medical condition, which we took an oath to alleviate when possible. If the treatment is appropriate and well documented with the current safeguards in place, there should be no fear."
Most respondents who elaborated on their answers, however, drew a sharp distinction between patients with chronic conditions and the terminally ill. Many noted that they do not prescribe narcotics to patients with chronic conditions, refer them to pain management specialists, and are vigilant when it comes to chronically ill patients who tend to "lose" prescriptions too often. When it comes to treating the terminally ill, however, respondents spoke in a single voice: treat their pain.
"Terminal patients should be able to get whatever they need whenever they need it," wrote one. "Terminal patients get whatever they need," said another. A third noted, "Terminal patients should never be allowed to suffer with pain because of inadequate treatment, especially fear of addiction: what difference does it make if they are going to die addicted to narcotics?"

Never Stop Learning

Kendra Campbell, MD, Psychiatry/Mental Health, 02:51PM Dec 4, 2010

 

"Cultivate the society of the young, remain interested, and never stop learning." -- Marcus Tullius Cicero

I’ve always been intrigued by learning new things. I believe that my spark for learning was ignited by my phenomenal parents. Some of the first memories I have as a child are of my parents taking the family on hikes through the Shenandoah National Park in Virginia. I remember my mother pointing out interesting looking flowers and trees, naming their genera and species, and sharing with us fascinating tidbits about them. When I was a child, we had very little access to television, and I can recall complaining to my father, “dad, I’m bored!” He would frequently respond with, “then go read the encyclopedia.” I would walk up to the shelf of encyclopedias, pick a random letter off the shelf and read everything there was to know about things that started with the letter “K.” (Ahhh, life before Wikipedia!)
Although I have about 19 years of formal education under my belt, there’s still so much about the world that I don’t know and don’t understand. But my hunger to learn about the world around me continues to drive me to seek out more opportunities and experiences.
Before I truly understood what being a doctor was all about, I thought that medical school was the golden mecca. In my ignorance, I believed that medical school was where you learned how to be a doctor. How very wrong I was! 
When I first started residency, I thought, “okay, this is where I will really become a doctor...where I will learn all there is to know about my specialty.” Well, it turns out that I was wrong again!
The lesson that I’ve discovered is that being an excellent physician truly means being a lifelong learner. You will never know everything. And the pace at which we are making new discoveries ensures that if you stop reading, you will quickly be “behind the times.” 
But it’s not just about keeping up with all the new scientific facts and discoveries, it’s actually quite a bit more complicated than that. To be a great healer, one must never stop listening to their patients. One must continue to see each patient as an opportunity to learn something new about people, how to heal them, and how to heal oneself.
Now that I’m a resident, I am in the unique and extraordinary position of being both a student and a teacher. I learn something new every day from my patients, the nurses, and the attendings. But I also get to impart some knowledge to the upcoming batch of doctors. 
A few days ago, I had a medical student tell me that she had learned many skills from me, which she would carry with her for the rest of her medical career. This was a momentous reminder to me of the power and gift that is teaching. 
I think the philosopher and writer, Jiddu Krishnamurti put it well: 
"There is no end to education. It is not that you read a book, pass an examination, and finish with the education. The whole of life, from the moment you are born to the moment you die, is a process of learning."

Experiencing Happiness as a Medical Student











Joshua Batt, Medical Student, 03:39PM Dec 5, 2010

 Is your happiness conditional? Do we delay the experience of feeling happy until we have achieved the next step? At one time happiness was conditional on getting into medical school, next was passing the boards, then it is graduating medical school and finally when we become an attending...then we will be happy. What is wrong with being happy now in the role we fill today?

Srikumar Rao's recent discourse, "Plug Into Your Hard Wired Happiness," really drives home the point that we can enjoy life as it is without setting emotional pleasure aside to await a measurable outcome. He encourages investing not only in the outcome, but also in the process. Unfortunately, we are focused too often on the end goal without seeing the smaller steps before us, whether we fail or succeed.
This principle can be easily applied to life as a medical student. We strive every day to choose the right answers on exams, please our clinical professors, and learn extensive amounts of information for future use. There will be many times when we fall short of an errorless performance. If we recognize the role we are playing now as students, we will make the progress needed to obtain the final outcome we all had in mind at the beginning. Invest in the process and enjoy the journey, it is just as important as the end product.
I love being a medical student. It pushes me to explore my interpersonal, critical thinking, and knowledge based skills. I have made my fair share of mistakes on exams and with my clinical preceptors. Like a child experiencing something for the first time, it is still a wonderful exploration of who I am and who I want to be, despite the difficulties. Don't wait until the end to experience happiness; you might just put it off again. Find ways to be happy every day, even when the going gets tough.

Science Explains Why Breaking Up Is Hard to Do


Helen Fisher, a biological anthropologist at Rutgers University in New Brunswick, New Jersey, knows all about love. She has observed the brain regions associated with romantic love light up as a man gazes at his inamorata, both in new relationships and in decades-long marriages. Fisher seems to have become a bit jaded by years of Hallmark moments, however. “Who cares about people who are happily in love?” she wants to know. “It’s when you’ve been rejected that you turn into a menace.” So she has started exploring the science of heartbreak instead.
In a study published in May, Fisher and her colleagues asked 15 people who had recently been dumped but were still in love to consider two pictures—one of the former partner and one of a neutral acquaintance—while an MRI scanner measured their brain activity. When looking at their exes, the spurned lovers showed activity in parts of the brain’s reward system, just as happy lovers do. But the neural pathways associated with cravings and addictions were activated too, as was a brain region associated with the distress that accompanies physical pain.
Rejected lovers also showed increased neural response in regions involved in assessing behavior and controlling emotions. “These people were working on the problem, thinking, what did I do, what should I do next, what did I learn from this,” Fisher says. And the longer ago the breakup was, the weaker the activity in the attachment-linked region. In other words: Love hurts, but time heals.

How Can Leg Cramps Be Treated?

Jodi H. Walker, PharmD
Adjunct Faculty, Albany College of Pharmacy, Albany, New York; Clinical Pharmacy Coordinator, VA Medical Center, Bath, New YorkPosted: 06/14/2010


Idiopathic leg cramps are presenting more and more frequently in the healthcare community. Leg cramps have historically been underreported. However, as patients become increasingly informed through television and the Internet and become aware of such conditions as the restless legs syndrome, treating leg cramps is a common issue facing healthcare providers today.
Although quinine sulfate has been shown to be efficacious in treating leg cramps, the Food and Drug Administration (FDA) banned over-the-counter use in 1994 due to risk for potentially fatal hypersensitivity reactions, thrombocytopenia, and cardiac arrhythmia.[1] In 2006, the FDA banned marketing of unapproved prescription quinine products.[2] Quinine remains available by prescription for treatment of malaria, but its risks as a preventive or treatment for leg cramps outweigh any potential benefit.[2]
Nonpharmacologic therapy is not well-established but may warrant an initial trial before treatment with medication. Hydration, warm or cold compresses, exercising, or calf stretches may provide some benefit.[3]
Although no specific medical treatment is indicated for leg cramps, several drugs have been used with varied success. Calcium-channel blockers, such as diltiazem, have been used to treat nocturnal leg cramps. Vitamin B complex (including 30-mg vitamin B6) has also shown effectiveness.[4]
Patients with chronic leg cramps should consult with their healthcare provider to investigate underlying causes. A differential diagnosis is important when patients with leg cramps are being examined, because many disorders, such as tetany, myalgia, the restless legs syndrome, and peripheral vascular disease, can have symptoms that present as leg cramps.[3]
Quinine continues to be used off-label to treat nocturnal leg cramps; however, an FDA postmarketing review states that there are no reliable data to support its use, and although it is often effective, serious adverse effects have occurred.[2] The American Academy of Neurology systematically reviewed the available evidence on symptomatic treatment of muscle cramps and their recommendations include the following[4]:
  • Consider vitamin B complex or calcium-channel blockers, such as diltiazem.
  • Avoid routine use of quinine.
  • Potentially consider quinine for an individual trial once side effects are evaluated; side effects must be carefully monitored.

Doctors Claim HIV-Positive Patient Cured by Stem Cells

German doctors announced what could be ground-breaking news in the fight against HIV and AIDS. An HIV-positive patient, who had developed acute myeloid leukemia, is said to have been cured of his HIV infection after a bone marrow transplant, which was performed in 2007.

The 'Berlin Patient,' a U.S. citizen named Timothy Ray Brown, underwent a procedure in which HIV-resistant stem cells from an individual with an unusual genetic profile were introduced into his body. The donor patient's CD4 cells lacked the CCR5 co-receptor -- the most common variety of HIV uses CCR5 co-receptors as a "docking station," attaching to it in order to enter and infect CD4 cells. People with this particular genetic mutation are almost completely protected against infection.

Brown underwent grueling treatment for leukemia, two stem cell transplants and also suffered from a serious neurological disorder, which required a brain biopsy. Before the stem cell transplant he received chemotherapy treatment that destroyed most of his immune cells, as well as total body irradiation and received immunosuppressive drugs to prevent rejection of the stem cells. After all of this, HIV was undetectable by both viral load testing (RNA) and tests for viral DNA within cells.

In an interview with the German news magazine, Stern, Brown was asked if might have just decided to live with HIV rather than undergo this lengthy and difficult process. "Perhaps," he answered. "Perhaps it would have been better, but I don't ask those sorts of questions anymore."

Berlin doctors published his detailed case history in the New England Journal of Medicine in February 2009. Now they've published a follow-up report in the journal Blood, saying: "It is reasonable to conclude that cure of HIV infection has been achieved in this patient."

The revelations about the 'Berlin Patient' point to the fact that a cure for HIV could be developed using genetically engineered stem cells. NAM Aidsmap reports that the German researchers and San Francisco-based immunologist Professor Jay Levy are stressing the importance of suppressing CCR5-bearing cells, either through transplants or gene therapy.

Dr. David J. Ores, a general practitioner on the Lower East Side of Manhattan says that while the thought of a cure for HIV is appealing, he's not sure if this one case is the answer.

"This patient has many unique factors," Ores told AOL Health. "He had leukemia. Twice. He had all sorts of chemotherapy and radiation. Twice. His genetics are unique to himself (like anyone else). The HIV could be dormant for now. We also don't know which sub-type of HIV he had. Or if he had other infections in the past which effect his immune system."

Ores goes so far as to question whether the 'Berlin Patient' actually had HIV in the first place. "Maybe his leukemia affected the HIV test since HIV is, in fact, leukemia as well. Recall, HIV was originally classified as 'HTLV type one' which stands for Human T-Cell Leukemia Virus (HTLV). So maybe his other leukemia affected the test for the other HIV leukemia (HIV)."

Still, Ores says that if the research is indeed valid, any advancements it creates toward finding a cure would be a positive thing.

Last year, several US research groups announced they had received funding to explore the development and implantation of CCR-5 deficient stem cells.

But even if these techniques prove to be successful, they will no doubt be very expensive, meaning that they would be reserved for people with no treatment options left, or cancer patients already requiring a bone marrow transplant.

The 'Berlin Patient's' road to recovery was not an easy one -- he endured chemotherapy, immunosuppresive drugs and stem cell transplants -- but in the end, his tough journey could pave the way for advancements toward an eventual cure for HIV that all people can benefit from.

Estrogen Alone is Effective for Reducing Breast Cancer Risk

Newswise — SAN ANTONIO — While endogenous estrogen (i.e., estrogen produced by ovaries and by other tissues) does have a well-known carcinogenic impact, hormone replacement therapy (HRT) utilizing estrogen alone (the exogenous estrogen) provides a protective effect in reducing breast cancer risk, according to study results presented at the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 8-12. 

“Our analysis suggests that, contrary to previous thinking, there is substantial value in bringing HRT with estrogen alone to the guidelines. The data show that for selected women it is not only safe, but potentially beneficial for breast cancer, as well as for many other aspects of women’s health,” said lead researcher Joseph Ragaz, M.D., medical oncologist and clinical professor in the faculty of medicine, School of Population and Public Health at The University of British Columbia, Vancouver, BC, Canada.

“These findings should intensify new research into its role as a protective agent against breast cancer,” he added.

Ragaz and colleagues reviewed and reanalyzed data from the Women’s Health Initiative (WHI) hormone replacement therapy trials. WHI is a national health study that focuses on strategies for preventing heart disease, breast and colorectal cancer, and fracture in postmenopausal women. The WHI was launched in 1991 and includes more than 161,000 U.S. women aged 50 to 79 years. 

“Over the last 30 years HRT has been used almost indiscriminately by women expecting the benefit of reducing cardiac risks, while providing a protective effect against bone fracture, and improving overall quality of life,” said Ragaz. “The WHI results as originally interpreted led to a major pendulum swing against HRT.”
The WHI HRT trial consisted of two cohorts of women; the estrogen-alone group of women without a uterus and the estrogen-plus-progestin group of women with a uterus. 

Ragaz and colleagues reanalyzed the WHI studies in more detail and found that subsets of women with no strong family history of breast cancer who received estrogen alone had a significantly reduced breast cancer incidence. In addition, the 75 percent of women without benign disease prior to the trial enrollment also had a reduced breast cancer risk. 

“Reduction of rates of breast cancer in the majority of women who are candidates for estrogen-based HRT is a new finding because estrogen was always linked with a higher incidence of breast cancer,” Ragaz said, “yet estrogen administered exogenously is actually protective for most women.”

Based on the results of this current analysis, Ragaz suggested that “while the use of HRT with estrogen alone may reduce the risk of breast cancer and may also be appropriate to manage menopausal symptoms, further research is warranted to elaborate on the optimum treatment regimen, to refine the selection of ideal candidates for estrogen therapy, and to understand the estrogen mechanisms that support the prevention of human breast cancer.” 

“The recommendations based on prior analyses of the results of the WHI HRT studies was not to use HRT, but we are optimistic this will change,” he said. “Our conclusion, based on the data presented, should enhance considerations for an early approval of HRT based on estrogen-alone for the majority of selected women suffering with menopausal symptoms and galvanize new research on HRT to define the optimum regimens for individual women.”

WOMEN, DEPRESSION AND OBESITY: WHAT'S EATING YOU?


Washington, DC (December 14, 2010) — The Society for Women’s Health Research (SWHR) presented the topical Capitol Hill briefing, Holiday Blues: Women, Depression and Obesity on Thursday, December 9, which featured four panelists detailing the links between depression and obesity.

Obesity is the newest health threat due in large part to American’s sedentary lifestyle and poor food choices. Co-morbidities of obesity include depression, heart disease, stroke, type II diabetes, hypertension, some cancers, osteoporosis and more. Sex differences in obesity play a role in fat distribution, higher financial burden on women, and incidence rates. According to the Centers for Disease Control, in 2008 33.2% of females were obese, with a body-mass index (BMI) of 30 or higher.

Belinda Needham, PhD, Assistant Professor and Director of Graduate Studies at the University of Alabama at Birmingham, spoke to the effects of obesity and depression, “17% of women will experience serious depression; females are two times as likely to be depressed as males, and women gain weight faster than men.” Needham presented findings from a community study to gauge the effects of obesity on depression and discovered women had higher BMIs at the start of the study and ended up larger than men at the end of the study. She concluded that depression led to weight gain and not the other way around.

“Elevated depressive symptoms affect over 25% of adolescents, and adolescent girls with elevated depressive symptoms are 2.5 times more likely to develop obesity at a later point in time compared to girls without depressive symptoms,” said Lauren B. Shomaker, PhD, Adjunct Scientist in the Unit on Growth and Obesity, National Institute of Child Health and Human Development. “Depressive symptoms lead to an increase in stress-induced eating, which results in obesity. And depression is theorized to alter physical fitness by a loss of pleasure in previously enjoyed physical activities.”

Fortunately, there are researchers leading studies to reverse this trend. Jay Breines, Executive Director, Holyoke Health Center, launched a pilot program at his health center in Holyoke, Mass. to combat obesity and teach proper nutrition and exercise habits to high-risk populations. His program integrated physicians, dentists, nurses, outreach workers, and promotoras among many others to provide a full care team for the participants to fight obesity and stop depression from taking hold. Breines closed with an advisory message to fellow community health organizers battling obesity, “We must engage at the community level to save money on our healthcare system.”

Christine Ferguson, Director, STOP Obesity Alliance and Research Professor, George Washington University School of Public Health and Health Services, outlined the obesity cost burden. Ferguson’s research team found the overall annual costs of being obese are $4879 for an obese woman and $2646 for an obese man. “There is a real, tangible economic impact for those women who are obese in our society,” said Ferguson. Obese women are paid less than average-weight women whereas obese men are paid the same as average-weight men. This can be partly attributed to social stigmatization and the already present gender wage gap.

“The key to obesity policy is to relate more to the health aspect, and less the aesthetic,” said Ferguson. Focusing on health versus looks may decrease depression and boost self-esteem. We need to support programs that target adolescents and teach healthy lifestyle habits in order to stave off depression as well as obesity.

Depression may lead to weight gain and vice versa, thus treatment for either should target both mind and body. Properly training physicians on weight-related issues, providing health and nutrition centers in high-risk communities, and focusing on the health aspects of obesity are just a few more ways to fight the fat and, in turn, defeat depression this holiday season and beyond.

SPINA BIFIDA: HOW TO PROTECT YOURSELF AND YOUR BABY


Jennifer Wider, MD
SWHR Contributing Writer
October 25, 2010

October marks National Spina Bifida Awareness Month, a condition that affects thousands of American babies each year.

Spina Bifida is a birth defect caused by the incomplete closing of the neural tube during embryonic development. The neural tube is a structure that ultimately forms the baby’s brain and spinal cord and their surrounding tissues. In normal fetal development, the neural tube forms early on in pregnancy and closes several weeks thereafter. In babies with Spina Bifida, a portion of the tube fails to close properly, which can lead to defects in the back bone and spinal cord.

According to statistics from the Spina Bifida Association of America (SBAA), Spina Bifida is the most common, permanently disabling birth defect in the United States. Every day, roughly eight babies are born with Spina Bifida or a related birth defect in this country.

While the exact cause of Spina Bifida is not entirely known, there are several recognized risk factors. According to information from the Mayo Clinic’s Foundation for Education and Research, the following are the most common risk factors:
  • Family history: Women who have given birth to one child with a neural tube abnormality seem to have a higher risk of occurrence in subsequent children.
  • Race: Spina Bifida seems to more common in Caucasian and Hispanic populations.
  • Folic Acid deficiency: A nutritional deficiency of folate (or folic acid), vitamin B9, increases the risk of Spina Bifida and many other neural tube defects.
  • Certain medications: Research studies have shown that certain drugs including anti-seizure medications may interfere in the body’s ability to utilize folic acid and can lead to an increase in neural tube problems.
  • Obesity: Women who are obese prior to and during their pregnancies have a higher risk for Spina Bifida and other known neural tube deformities.
While some of the risk factors cannot be controlled, others including diet and vitamin supplements clearly make a difference. “Folic acid dietary supplementation appears to reduce the occurrence of Spina Bifida and other neural tube defects,” explains William Graf, MD, Director of the Yale/New Haven Hospital Spina Bifida Program in Connecticut. “Clinicians in the United States should advise women without a family history of NTDs (neural tube defects), who anticipate a pregnancy to take .4-.8 mg (400-800 micrograms) of folic acid daily.”

According to data from the SBAA, “if all women who could possibly become pregnant were to take a multivitamin with folic acid, the risk of neural tube defects like Spina Bifida could be reduced by up to 70 percent.” Because many pregnancies are unplanned, most experts recommend women in their childbearing years to take the recommended dose of 400 micrograms of folic acid. Folic acid can be found in foods including: dark, green leafy vegetables, whole wheat products, nuts and seeds, oranges, grapefruits and fortified cereals and grains.

It is important for women to realize the cause of Spina Bifida is not clearly understood and most likely results from an interplay of many factors, including: nutritional, environmental and genetic. According to Dr. Graf, “there has been a slight miscommunication that folic acid will completely prevent this very complex, early neurodevelopmental disorder.” Thus, if a woman has a family or personal history of neural tube defects, it is important she speaks to her health care provider about how to further reduce the risk for her offspring.

2010 AHA Guidelines: The ABCs of CPR Rearranged to "CAB"

News Author: Emma Hitt, PhD
CME Author: Laurie Barclay, MD

CME/CE Released: 10/27/2010; Valid for credit through 10/27/2011.

October 20, 2010 — Chest compressions should be the first step in addressing cardiac arrest. Therefore, the American Heart Association (AHA) now recommends that the A-B-Cs (Airway-Breathing-Compressions) of cardiopulmonary resuscitation (CPR) be changed to C-A-B (Compressions-Airway-Breathing).

The changes were documented in the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, published in the November 2 supplemental issue of Circulation: Journal of the American Heart Association, and represent an update to previous guidelines issued in 2005.

"The 2010 AHA Guidelines for CPR and ECC [Emergency Cardiovascular Care] are based on the most current and comprehensive review of resuscitation literature ever published," note the authors in the executive summary. The new research includes information from "356 resuscitation experts from 29 countries who reviewed, analyzed, evaluated, debated, and discussed research and hypotheses through in-person meetings, teleconferences, and online sessions ('webinars') during the 36-month period before the 2010 Consensus Conference."

According to the AHA, chest compressions should be started immediately on anyone who is unresponsive and is not breathing normally. Oxygen will be present in the lungs and bloodstream within the first few minutes, so initiating chest compressions first will facilitate distribution of that oxygen into the brain and heart sooner. Previously, starting with "A" (airway) rather than "C" (compressions) caused significant delays of approximately 30 seconds.

"For more than 40 years, CPR training has emphasized the ABCs of CPR, which instructed people to open a victim's airway by tilting their head back, pinching the nose and breathing into the victim's mouth, and only then giving chest compressions," noted Michael R. Sayre, MD, coauthor and chairman of the AHA's Emergency Cardiovascular Care Committee, in an AHA written release. "This approach was causing significant delays in starting chest compressions, which are essential for keeping oxygen-rich blood circulating through the body," he added.

The new guidelines also recommend that during CPR, rescuers increase the speed of chest compressions to a rate of at least 100 times a minute. In addition, compressions should be made more deeply into the chest, to a depth of at least 2 inches in adults and children and 1.5 inches in infants.

Persons performing CPR should also avoid leaning on the chest so that it can return to its starting position, and compression should be continued as long as possible without the use of excessive ventilation.
9-1-1 centers are now directed to deliver instructions assertively so that chest compressions can be started when cardiac arrest is suspected.

The new guidelines also recommend more strongly that dispatchers instruct untrained lay rescuers to provide Hands-Only CPR (chest compression only) for adults who are unresponsive, with no breathing or no normal breathing.

Other Key Recommendations
Other key recommendations for healthcare professionals performing CPR include the following:
  • Effective teamwork techniques should be learned and practiced regularly.
  • Quantitative waveform capnography, used to measure carbon dioxide output, should be used to confirm intubation and monitor CPR quality.
  • Therapeutic hypothermia should be part of an overall interdisciplinary system of care after resuscitation from cardiac arrest.
  • Atropine is no longer recommended for routine use in managing and treating pulseless electrical activity or asystole.
Pediatric advanced life support guidelines emphasize organizing care around 2-minute periods of continuous CPR. The new guidelines also discuss resuscitation of infants and children with various congenital heart diseases and pulmonary hypertension.

The authors of the guidelines have disclosed no relevant financial relationships.

Assessing the Lower Extremities in the Geriatric Patient

Mark E. Williams, MD
Posted: 11/08/2010

Overview

This presentation is primarily concerned with the orthopaedic and vascular aspects of the lower extremity examination, with a focus on the legs. For more detailed information on assessing the feet, see Evaluating Foot Pain in Elderly Patients . The assessment of balance and gait and the neurologic evaluation of the lower extremities are beyond the scope of this presentation.

Assessment of the Hip in the Geriatric Patient

General Evaluation of the Hip

Observations of standing posture. The hip cannot be inspected or palpated directly; therefore, most inferences derive from changes in movement. Observe the patient's standing posture because hip problems will tend to cause the affected foot to advance slightly and rotate slightly inward. Also check Trendelenburg's sign; have the patient lift the right leg and observe whether the left hip elevates, which is normal, or does not (a positive test). Repeat on the other side. A positive test suggests degenerative joint disease, weakness of the gluteus, or hip dislocation. Seeing a compensatory lordosis when the hip is extended suggests a fixed flexion deformity of the hip. You can confirm your impression with Thomas' Test below.
Thomas' Test for Fixed Flexion Deformity of the Hip
First check for lumbar lordosis. With the patient lying supine, try to place your left hand, palm up, between the patient's low back and the table. If your hand is able to be inserted between the back and the table then the patient has a lumbar lordosis. If not, then the deformity is not present
Next, ask the patient to flex the normal leg and pull it to the chest. If there is no fixed flexion deformity, the opposite outstretched leg will remain on the table. If the deformity is present, pelvic rotation as the normal leg is flexed will cause the opposite leg to rise off the examination table.

Hip range of motion. Next, perform the hip isolation test to observe the range of motion. With the patient prone, flex the knee to about 90° and move the foot medially and laterally so that the knee also swings medially and laterally. Limited range of motion implies degenerative joint disease of the hip. This test isolates the hip so that extra-articular causes of discomfort are minimized.

Hip Pain After a Fall

First, inspect the leg. Consider the following:
  • If it is foreshortened and externally rotated, consider fracture below the femoral neck (intertrochanteric fracture);
  • If the leg is externally rotated but not foreshortened, consider fracture of the femoral shaft;
  • If the thigh is externally rotated, flexed, and abducted, consider anterior dislocation; and
  • If the thigh is internally rotated and adducted with a very prominent greater trochanter, consider posterior dislocation.
Now check for fracture with the use of osteophony (Hueter's sign). This test is extremely helpful in evaluating patients during home visits or in the nursing home. Place the diaphragm of your stethoscope on the pubic symphysis. Gently percuss each kneecap with your forefinger. An intact bone will produce a clear, bright tapping sound. A hip fracture will give a muffled, distant sound. Other approaches use a tuning fork on the patella or listening over each iliac crest as opposed to the pubic symphysis.

Chronic Hip Pain or Decreased Range of Motion

As you perform this assessment, keep in mind the possibility of referred pain from the knee (see below).
Patrick's test. To perform Patrick's test, place the patient's ankle on the contralateral knee and then gently press down on the flexed knee. Pain in the hip suggests osteoarthritis of the hip; pain radiating from the back down the leg suggests radiculopathy; and pain in the lower spine suggests compression fracture.
Laguerre's test. With the patient supine, grasp the heel on the symptomatic side and passively flex the knee and hip and rotate the patient's hip. Pain over the greater trochanter suggests bursitis, whereas pain in the hip and groin suggests degenerative joint disease.
Trendelenburg's sign. Have the patient stand and transfer the weight to the nonpainful leg. If the painful buttock drops and becomes flaccid, suspect severe degenerative joint disease, weakness of the gluteus, or hip dislocation.
Palpate the anterior iliac spine. Palpate along the anterior iliac spine and inguinal ligament. Increasing dysesthesia along the anterior thigh indicates meralgia paresthetica.

Additional Hip Assessment Pearls

  • Feeling a crepitant sensation when palpating over a bone in the absence of infection suggests sarcoma (Dupuytren's sign); and
  • Flattening of the thigh when a patient lies supine suggests upper motor neuron disease (Heilbronner's sign).

General Evaluation of the Knee

It is normal for both the ankles and the knees to touch. Being knock-kneed (knees touch but ankles do not) involves a valgus deformity of the knee. Bow-leggedness (ankles touch but knees do not) is a varus deformity of the knee. If the knees curve backward in the lateral dimension, there is a genu recurvatum deformity. Osteoarthritis will produce bony enlargement, which is sometimes magnified by coincident quadricep muscle atrophy. Look for scars that indicate previous knee surgery.
Check knee range of motion. Observe passive knee range of motion by gently flexing and extending the knee with the patient sitting or supine. Decreased range of motion suggests degenerative joint disease. Increased lateral movement suggests damaged ligaments.
Check for crepitus. Check for crepitus in the knee joint by listening for the crunching, popping sound (or feeling) on joint movement. Finding no crepitus is normal. If crepitus is present, it suggests degenerative joint disease. The location defines the affected compartment, so that anterior, lateral, or medial crepitus suggests knee degenerative joint disease in those respective locations. Crepitus on extension suggests patellofemoral syndrome.
Check for effusion. Now search for knee effusion. Feel for a spongy movement of the patella and look for a bulge between the patella and the condyles. If there is any spongy downward movement of the patella when the leg is fully extended, then an effusion is present. In addition, you can milk the fluid from the medial side with your forefingers and middle fingers and then push with your thumbs from the lateral side just below the patella. Seeing a medial bulge (bulge sign) suggests effusion.
Check the tibial and femoral condyles positions. Tibial condyles displaced posteriorly to the femoral condyles suggest a prior posterior cruciate ligament tear. Tibial condyles displaced anteriorly to the femoral condyles suggest a prior anterior cruciate ligament tear.

Anterior Knee Pain

Check for bony deformity.
Check for effusion (vide supra). If present, patellar effusion will present as spongy ballottement, bulging of the joint, or a fluid wave. Check for tenderness and swelling over the quadriceps muscles. The presence of pain suggests quadriceps rupture or strain.
Check for patellar tenderness. Doughy swelling above the patella suggests suprapatellar bursitis (housemaid's knee). Swelling and tenderness on the patella suggest prepatellar bursitis (roofer's knee), usually brought on by constant kneeling. Marked tenderness and swelling over the patella suggest patellar fracture. Tenderness below the patella without swelling suggests tendonitis (jumper's knee). Swelling and tenderness below the patella suggest infrapatellar bursitis (pastor's knee).
Patellofemoral syndrome. Look for quadriceps atrophy, especially the vastus obliquus medialis. Also feel for tenderness behind the patella with palpation. Perform the patellar inhibition test. Stabilize the patella with your thumb and forefinger, and then gently try to push it toward the feet. Have the patient contract the quadriceps to move the patella upward. Pain and relaxation of the quadriceps is a positive test. Now move the patella medially and laterally with knee flexed to 30 degrees. Increased lateral mobility is a positive apprehension test. Voluntary contraction of the quadriceps when moving the patella laterally is also a positive test. Check for lateral patellar displacement with extension that resolves with flexion.

Pain Behind the Knee

Search for a popliteal mass. A nontender area of bogginess suggests a Baker's cyst. Feeling a pulsatile mass suggests popliteal artery aneurysm. Feeling a tender mass in the popliteal fossa suggests bursitis.
Look for focal or diffuse tenderness in the popliteal fossa. Focal tenderness in the medial popliteal fossa without a mass suggests a hamstring muscle strain. Diffuse tenderness and swelling suggest a ruptured Baker's cyst or deep venous thrombosis.

Medial Knee Pain

Palpate for tenderness. Check for an anatomic deformity and palpate the site of tenderness. Pain behind the knee suggests a hamstring tear. Exquisite tenderness medial and inferior to the tibial plateau suggests anserine bursitis. Tenderness midway between the femur and the tibia suggests medial collateral ligament damage. Tenderness anterior to the condyles suggests a medial meniscus tear.
Check for joint laxity. Now test for joint laxity with lateral movement. The degree of laxity defines the extent of medial collateral ligament tear. Pain in the lateral knee with this movement suggests lateral meniscus tear (Bohler's sign).
Check for meniscus tear. Employ McMurray's maneuver; with the patient supine, passively flex the knee until the heel hits the buttock. Rotate foot laterally and then extend the knee. A loud click over the lateral knee suggests a medial meniscus tear. Also check Apley's compression test. With the patient prone and the knee flexed to 90° (perpendicular to the examining table), push down and gently twist the foot. Pain or crepitus is a positive test. Payr's test is also useful. With the patient sitting cross-legged, push on the painful knee. Medial knee pain is a positive test.

Lateral Knee Pain

Check for anatomic deformity.
Palpate for tenderness. Palpate the site of tenderness with the knee straight and then flexed to 90°. Tenderness over the fibular head suggests fibular fracture. Tenderness between the femur and fibular head suggests lateral collateral ligament sprain. Tenderness just anterior to the femoral condyles suggests lateral meniscus tear. Tenderness over the lateral tibial condyle radiating over the lateral thigh suggests iliotibial band syndrome.
Check for joint laxity. Check for joint laxity by holding the knee and moving the foot medially. The amount of pain and the degree of laxity define the extent of lateral collateral ligament tear. Pain in the medial knee suggests medial meniscus tear.
Check for Ober's sign. With the patient supine, passively flex and abduct the leg, and then gently let go and have the patient maintain the leg position. Pain in the anterior thigh (positive Ober's sign) suggests tensor fascia lata syndrome. Pain in the lateral knee suggests iliotibial band syndrome.
Look for a meniscus tear. See "Check for Meniscus Tear" under "Medial Knee Pain," above.

A Knee That Gives Way

Check the basic landmarks for anatomic deformity.
Examine the anterior cruciate ligament. Perform the drawer test by pulling out on the tibia to see how far the tibia slides anteriorly over the femur. Sensing a sharp stopping point of movement is normal. Noting greater than 2 mm of movement and/or a boggy stopping point suggests a tear. Rotational movement (where only 1 condyle moves) suggests tear of the corresponding collateral ligament.
Now check the drawer test with the patient prone. Lachman sign is basically a drawer sign with the posterior knee supported to relax the hamstrings.
Check the Galway-MacIntosh test. With the patient supine, passively flex the hip with the knee extended. Anterior movement of the tibia more than 2 mm suggests a tear. Confirm by applying valgus force to the leg while passively flexing the knee. A sharp reduction of the subluxation at 20°-40° flexion is a positive test.
Check the posterior cruciate ligament. Perform the drawer test to see how far the tibia slides posteriorly over the femur. A sharp stopping point of movement is normal. Greater than 2 mm of movement and/or a boggy stopping point suggests a tear. Rotational movement, where only 1 condyle moves, suggests a tear of the corresponding collateral ligament.
Check for posterior sag by supporting the distal femur with pillows and see whether the tibia is posteriorly displaced. With the patient supine and knee flexed at 90°, push posteriorly on the tibial plateau. Posterior movement suggests a tear.
Check for Godfrey's sign. With the patient supine, passively flex at the hip with the knee in full extension. Pull up on the distal foot to 90° with varus and external rotation. Posterior movement of the tibia suggests a tear.
Check the collateral ligaments. Check for joint laxity with lateral movement. The degree of laxity defines the extent of medial collateral ligament tear. Hold the knee and move the foot medially. The amount of pain and the degree of laxity define the extent of lateral collateral ligament tear.
Check for meniscal tear. See "Check for Meniscus Tear" under "Medial Knee Pain," above
Palpate the lateral knee. Tenderness suggests proximal fibular fracture.

Additional Knee Assessment Pearls

  • A decrease in knee pain by forward flexion and lateral rotation of the foot suggests medial meniscus injury (Bragard's sign).
  • Increased anterior-posterior movement of the tibia over the femur with a click or pain suggests damage to the anterior or posterior cruciate ligaments (drawer or Rocher's sign).
  • With the patient sitting cross-legged, exert downward pressure along the medial aspect of the knee. Medial knee pain indicates a posterior horn lesion of the medial meniscus.
  • Anesthesia in the popliteal fossa suggests neurosyphilis (Bekhterev's sign).

General Evaluation of Lower Extremity Circulation

Inspect the legs from the groin to the feet noting any asymmetry, skin changes, hair distribution, varicosities, or edema. Signs of vascular insufficiency include pallor, coolness, cyanosis, atrophy, loss of hair, pigmentation along the shin or ankles, or ulcers. Check the capillary refill by pinching the great toes and noting the time that it takes for the color of the nail beds to return to normal (should be less than 3 seconds).

Arteries in the Legs

Assessing the femoral artery. Palpate the right femoral artery pulse by placing the index and middle fingers of your left hand over the patient's right inguinal ligament about midway between the right anterior superior iliac spine and the right symphysis pubis. Feel the opposite side with your right hand at the left inguinal ligament appreciating both pulses. Inequality of the pulse suggests vascular disease.
Now check the radial and femoral pulses on the right side. The femoral pulse should be felt before the radial pulse; if it is not, suspect aortoiliac disease. Listen for a vascular bruit. If one is present, observe whether it increases when the patient flexes and extends the ankle rapidly. Then, compress the femoral artery high in the femoral triangle near the inguinal ligament in the anterior and medial thigh. If the bruit increases, consider occlusion of the profunda artery. If the bruit decreases, consider occlusion of the common femoral artery or the proximal femoral artery. If the patient has a femoral popliteal bypass graft, hearing the bruit decrease with compression suggests that occlusion of the graft is eminent.
Popliteal artery. With the patient supine, place both hands around the knee and feel in the popliteal space. Slowly lift the knee until it is about 90°. If you cannot detect a pulse, then stop at that point. Feel the skin temperature over the shin. Normally, you would detect a point of warmth at the upper portion of the anterior thigh. Coolness in this area suggests acute vascular insufficiency. Note, however, that in chronic popliteal disease, vascular collaterals may cause the involved knee to feel warmer rather than cooler.
Dorsalis pedis and posterior tibial arteries. The dorsalis pedis pulse is usually felt along the dorsum of the foot just lateral to the extensor tendon of the great toe. The posterior tibial pulse is usually just behind and slightly below the medial malleolus.

Deep Venous Obstruction

With the patient supine, check the veins over the tibial plateau. Dilated veins that do not collapse with leg elevation suggest deep venous obstruction (Pratt's sign). If the skin on 1 leg is warm and stiff to a pinch (secondary to edema), then deep venous thrombosis is also indicated (Rose's sign). Measure the difference in circumference between the normal and distended leg -- both thighs and calves. Greater than 2.5 cm difference between the calves and greater than 2 cm between the thighs suggest deep venous thrombosis. Deep venous thrombosis is also suggested by the following:
  • Tenderness to percussion of the medial surface of the tibia (Lisker's sign);
  • Cough-induced pain that disappears when the proximal vein is compressed (Louvel's sign); and
  • Asymmetric tenderness to blood pressure cuff inflation at less than half the pressure of the opposite side (Löwenberg's sign).

Varicose Veins

Varicose veins with pulsations suggest tricuspid insufficiency. Hearing a murmur over the veins suggests tricuspid insufficiency. Dark purple discoloration of the skin with varicose veins suggests arteriovenous fistula.
Inspect the saphenous system for varicosities that will appear as large wormlike, tortuous vessels. Perform the manual compression test by having the patient stand and placing your right hand over the distal lower part of the varicose vein and your left hand over the proximal vein. Your hands will be about 15-20 cm apart. Compress the proximal portion of the varicose vein. If you feel a palpable pulsation in your distal hand, the test is positive.
Now perform Trendelenburg's test. Have the supine patient elevate the leg to 90° until the venous blood has drained from the great saphenous vein. Now place a tourniquet around the upper thigh of the patient's leg tightly enough to occlude the great saphenous vein but not the arterial pressure. Help the patient stand and look for venous filling. Slow filling (over 30 seconds) below the superficial veins while the tourniquet is applied is normal. Rapid filling of the superficial veins while the tourniquet is applied is abnormal, as is sudden additional filling of the superficial veins after the tourniquet has been released.

Additional Lower Extremity Circulation Pearls

  • Aneurysms of the abdominal aorta are associated with distal peripheral aneurysm.
  • Atherosclerosis, although a generalized metabolic disorder, tends to build up at bifurcations of major vessels. In the lower extremity, the superficial femoral artery becomes occluded at the adductor hiatus.
  • Patients with diabetes tend to have femoral-tibial occlusions, whereas nondiabetic patients tend to have ileal-femoral occlusions.

Assessment of Other Lower Extremity Conditions in the Geriatric Patient

Leg Fracture

Palpate over the greater trochanter. Pain suggests fracture if other signs are present. (Otherwise consider trochanteric bursitis or possible referred pain from the knee.) Laxity on palpation of the fascia lata, which connects the greater trochanter to the iliac crest, suggests femoral neck fracture (Allis' sign). Swelling along the inguinal ligament in a femoral neck fracture is called Laugier's sign. A transverse crease superior to the patella suggests a femoral fracture (Cleemann's sign). Ecchymosis and swelling along the inguinal ligament and inability to raise the thigh when the patient is sitting suggest fracture of the greater trochanter (Ludloff's sign). Limitation in the normal range of motion in the circular arc of the hip suggests proximal femoral fracture (Desault's sign). Relaxation of the extensor muscles of the thigh with intrascapular femoral fracture is called Langoria's sign. Increased diameter of the leg at the level of the malleoli suggests fibular fracture (Keen's sign of Pott's fracture).

Ankle Injury

Check landmarks for anatomic abnormality.
Ecchymoses and/or swelling. Ecchymosis under both malleoli with a broad-appearing heel suggests a calcaneal fracture. Ecchymosis and focal swelling over the fifth metatarsal suggest fracture of the proximal fifth metatarsal bone (Jones fracture). Swelling and tenderness over the lateral malleolus suggest a lateral sprain if anterior and inferior and a peroneal retinaculum sprain if on the posterior rim. Swelling and tenderness over the medial malleolus suggest a medial sprain, syndesmotic sprain, or tibialis tendonitis if posterior to the medial malleolus.
The talar tilt test. The talar tilt test is used to examine the integrity of the calcaneofibular or the deltoid ligament. Passively invert the foot and compare it with the opposite side. A > 10° difference implies a second- or third-degree lateral ankle sprain. The talus will tilt if both the talofibular and calcaneofibular ligaments are ruptured, but not with only 1 ruptured ligament (talar tilt sign).
Check for anterior movement of the calcaneus over the distal tibia. A firm endpoint and 4 mm of movement or less suggest a first-degree lateral sprain. Sensing a boggy endpoint and > 4 mm movement suggest a second-degree lateral sprain. Greater than 4 mm of movement and no endpoint suggest a third-degree lateral sprain.
Squeeze the malleoli together. Increased pain produced by squeezing the malleoli together suggests a syndesmotic sprain.
Externally rotate foot at the ankle. Increased pain produced by externally rotating the foot at the ankle suggests syndesmotic sprain.

Sciatica

Acute radicular low back pain (sciatica) radiates or shoots down 1 leg. The discomfort is often characterized as sharp, tingling, shooting, or "electrical" and may be exacerbated by coughing, straining, sneezing, or Valsalva maneuvers. It may occur in several ways, depending on the nerve roots affected. The pattern of weakness (if present) in the lower extremity is an important clue to the site of the neurologic dysfunction. Significant unilateral thigh and leg weakness suggests involvement by multiple nerve roots or peripheral nerves, although most peripheral nerve processes are not usually associated with back pain.
To differentiate sciatica from a hamstring injury, have the patient flex the hip with the leg straight until it feels painful and then have the patient dorsiflex the foot. A hamstring pull will not be painful, whereas with sciatica the pain will increase (Bragard's leg sign).
Other signs of sciatica include the following:
  • Pain on the contralateral side when the nonpainful side is flexed at the thigh and the leg is held in extension (Fajersztajn's sign);
  • Loss of sensation on the lateral portion of the foot (Szabo's sign);
  • Pain on straight leg raise that is relieved with leg flexion (Lasegue's sign);
  • Pain on adduction of the thigh (Bonnet's sign);
  • Pain in the buttocks when the great toe is hyperextended (Turyn's sign); and
  • Pain in the lower back or down the leg when the patient is supine (Linder's sign).

Signs of Endocrine or Metabolic Disorders

Symptoms in the legs can often indicate endocrine or metabolic disorders. Check for the following:
  • Cramping of the calves can be an early sign of diabetes mellitus (Unschuld's sign).
  • Difficulty walking up stairs or rising from a chair secondary to proximal muscle weakness suggests hyperthyroidism (Plummer's sign).
  • Leg weakness, pain on gently squeezing the calves, decreased knee-jerk reflexes, and anesthesia over the anterior thigh suggest Beriberi (Vedder's sign).
  • Hypocalcemia can be suggested when thigh flexion produces knee spasm and calf spasm (Pool-Schlesinger sign). Eversion of the foot when tapping over the peroneal nerve also suggests hypocalcemia (peroneal sign). Note: This is the author's favorite method to determine hypocalcemia because it seems to be the first to appear and last to disappear.
  • Tenderness to percussion over the tibia suggests chlorosis (Golonbov's sign).
  • Exquisite pain of the great toe when touching the fifth toe joint suggests gout (Plotz's sign).
  • Loss of hair on the posterior surface of the legs suggests gout (Tommasi's sign).

AHA/ASA Releases Updated Secondary Stroke Prevention Guidelines

News Author: Pauline Anderson
CME Author: Charles P. Vega, MD
CME/CE Released: 10/25/2010; Valid for credit through 10/25/2011

October 25, 2010 — New recommendations on metabolic syndrome treatment and acknowledgement of a place for stenting in the management of symptomatic carotid stenosis are among the changes seen in updated secondary stroke prevention guidelines from the American Heart Association (AHA)/American Stroke Association (ASA).
The new guidelines were published online October 21 in Stroke. The document notes that the American Academy of Neurology "affirms the value" of the guideline as an educational tool for neurologists and that it has been reviewed and the content affirmed by the American Association of Neurological Surgeons and the Congress of Neurological Surgeons.
The aim of the statement is to provide comprehensive and timely evidence-based recommendations on the prevention of ischemic stroke among survivors of ischemic stroke or transient ischemic attack, the authors write.
This and other AHA stroke-related statements are updated on a regular basis, with these secondary stroke prevention guidelines last being updated in 2006, said Robert J. Adams, MD, professor of neuroscience at the Medical University of South Carolina, Charleston, and a member of the review committee.
"We make a continual effort to get the best recommendations we can looking at the evidence, and as you'll see in some areas, we felt that we couldn't really make a recommendation because we felt we didn't have enough data," Dr. Adams told Medscape Medical News. "Those are basically by default or de facto areas where we think more research is needed."
This update is also among the first to flag new recommendations within the text of the document, said Dr. Adams. "We decided to point out to the reader what was new."
New Metabolic Syndrome Recommendations
All 3 recommendations pertaining to metabolic syndrome are new. The syndrome is a confluence of several physiological abnormalities that increase the risk for vascular disease. According to AHA/ASA criteria, metabolic syndrome is recognized when 3 of the following features are present:
  • increased waist circumference (≥102 cm in men; ≥88 cm in women),
  • elevated triglyceride levels (≥150 mg/dL),
  • reduced high-density lipoprotein cholesterol (<40 mg/dL in women; <50 mg/dL in men),
  • elevated blood pressure (systolic ≥130 mm Hg, or diastolic ≥ 85 mm Hg), and
  • elevated fasting glucose (≥100 mg/dL).
To prevent a secondary stroke or transient ischemic attack in patients who have metabolic syndrome, clinicians should treat the individual components of the syndrome that are also stroke risk factors, particularly dyslipidemia and hypertension, the new guidelines note.
Management of patients with metabolic syndrome should include counseling on diet, exercise, and weight loss to reduce vascular risks, but the utility of screening patients for metabolic syndrome after stroke has not been established.
There is considerable controversy surrounding this syndrome, largely because of uncertainty regarding its etiology and clinical usefulness, the authors write. The disorder has been related to an increased risk for diabetes, cardiovascular disease, and all-cause mortality.
The association between metabolic syndrome and risk for first ischemic stroke has been examined in several recent studies, with all except 1 confirming the association, but with only 1 study examining the association between metabolic syndrome and risk for stroke recurrence.
In the Warfarin Aspirin Symptomatic Intracranial Disease (WASID) trial, participants with metabolic syndrome were more likely to have a stroke, myocardial infarction, or vascular death during 1.8 years of follow-up than participants without metabolic syndrome (hazard ratio [HR], 1.6; 95% confidence interval [CI], 1.1 - 2.4; P = .0097). Patients with the syndrome were also at increased risk for ischemic stroke alone (HR, 1.7; 95% CI, 1.1 - 2.6; P = .012).
Cardiac features of metabolic syndrome improve with weight loss, which has also been shown to improve insulin sensitivity, lower plasma glucose, low plasma low-density lipoprotein cholesterol, lower plasma triglycerides, raise high-density lipoprotein cholesterol, lower blood pressure, reduce inflammation improve fibrinolysis, and improve endothelial function in patients with metabolic syndrome.
Carotid Artery Stenting
Also included in the revised guidelines is updated research pertaining to carotid artery stenting for extracranial symptomatic carotid disease, based on results of large clinical trials, including the Carotid Revascularization Endarterectomy vs Stent Trial (CREST), most recently reported.
Carotid endarterectomy is recommended for these symptomatic patients with high-grade stenosis (70% - 99%) if the perioperative morbidity and mortality risk is estimated at less than 6%, as well as for those with moderate stenosis (50% - 99%); neither stenting nor surgery is recommended for stenoses less than 50%.
However, the writing group notes that carotid artery stenting is indicated as an alternative to surgery for symptomatic patients at average or low risk for complications associated with endovascular intervention when the diameter of the lumen of the internal carotid artery is reduced by more than 70% by noninvasive imaging or more than 50% by catheter angiography.
"The recommendation is that for certain patients with symptomatic high-grade carotid stenosis and factors that make carotid endarterectomy not favorable, such as previous radiation therapy or previous surgery, or certain medical conditions which increase risk for surgery, that carotid artery stenting is a reasonable alternative," commented Dr. Adams.
Stenting in that setting is "reasonable when performed by operators with established periprocedural morbidity and mortality rates of 4% to 6%," the authors add — rates similar to those seen in stenting and surgery trials.
Finally, a new recommendation is that all of these patients receive optimal medical therapy, including antiplatelet therapy, statins, and a risk factor modification.
Atrial Fibrillation
New recommendations on the management of atrial fibrillation (AF) are based on data from the Atrial Fibrillation Clopidogrel Trial with Irbesartan for Prevention of Vascular Events (ACTIVE) study and ACTIVE A, an arm of the study that compared aspirin with clopidogrel plus aspirin in patients with AF who were considered unsuitable for vitamin K antagonist therapy.
Patients were considered "unsuitable" for warfarin based on physician judgment or patient preference — criteria that were somewhat controversial when this study was first presented. Trial results showed less stroke but more bleeding with clopidogrel plus aspirin vs aspirin alone.
In the new guidelines, however, authors write that "on the basis of uncertainty of how to identify patients who are 'unsuitable' for anticoagulation, as well as the lack of benefit in the analysis of vascular events plus major hemorrhage, aspirin remains the treatment of choice for AF patients who have a clear contraindication to vitamin K antagonist therapy but are able to tolerate antiplatelet therapy."
The combination of clopidogrel plus aspirin carries a bleeding risk similar to warfarin and so is not recommended for those with a hemorrhagic contraindication to warfarin, the authors note.
Another new recommendation is that for patients with AF who are at high risk for recurrent stroke, but who require temporary interruption of oral anticoagulation, bridging therapy with a low-molecular-weight heparin is reasonable, said Dr. Adams.
These new AF guidelines were written before regulatory approval of the oral thrombin inhibitor dabigatran, based on encouraging results in the previously reported Randomized Evaluation of Long-Term Anticoagulation Therapy (RE-LY) study.
"No recommendation will be provided for dabigatran in the current version of these guidelines because regulatory evaluation and approval has not yet occurred," the authors note in the document. "However, the availability of a highly effective oral agent without significant drug or food interactions that does not require coagulation monitoring would represent a major advance for this patient population."
They also discuss the WATCHMAN left atrial appendage occlusion device, studied in the Embolic Protection in Patients with Atrial Fibrillation (PROTECT-AF) trial as an alternative to oral anticoagulants. "This approach is likely to have the greatest clinical utility for AF patients at high stroke risk who are poor candidates for oral anticoagulation; however, more data are required in these populations before a recommendation can be made."
Intracranial Atherosclerosis
There is also new research in the area of intracranial atherosclerosis. "There is some new information on the use of antiplatelet agents; it actually didn't substantially change the guidelines, but it makes the choice somewhat easier, and provides additional information that we didn't have before," said Dr. Adams.
The new information was from the WASID trial, on which the recommendation for aspirin over warfarin is based. Aspirin doses of 50 to 325 mg/day are recommended, the authors write. Intracranial stenting is considered investigational at this time, and its utility is still unknown, they note.
As well, there is a new recommendation concerning maintenance of blood pressure, suggesting that for patients with stroke or transient ischemic attack caused by 50% to 99% stenosis of a major intracranial artery, long-term maintenance of blood pressure lower than 140/90 mm Hg and total cholesterol level lower than 200 mg/dL may be reasonable, and there is also a new recommendation against bypass surgery in these patients.
Conflict of Interest Scrutiny
Finally, another new element to these guidelines was the "scrutiny" of committee members reviewing the literature to minimize conflicts of interest, said Dr. Adams.
"How that was managed this time was that we were all given assignments in areas that were unrelated to anything we put on the conflict of interest form;" the upshot is that he was reviewing research, "that I have no interest in or ever spoken about."
All members of the writing group were required to complete and submit a disclosure questionnaire showing all such relationships that might be perceived as real or potential conflicts of interest.

How Are You Choosing a Specialty?


Joshua Batt, Medical Student, 05:32PM Nov 20, 2010

he cut was made, some dissection performed and the baby was pulled out. I was holding our patient's uterus in one hand and assisting my attending with the other during a scheduled cesarean section. All I could think was how this doctor's job is simply amazing. How many people can say that they get to open a person's body, pull out a living organism and twelve inches away, you can stare the patient in the face and have a discussion with them?

Between the work of the anesthesiologist and the obstetrician, I was enthralled by the situation. Their team effort and training made the operation a success. Baby was beautiful, mom and dad were happy and the medical crew had performed well. It was not a long procedure, but one that left me wondering if I could be doing this as a career. Yet another moment of reflection needed if I am ever going to decide what to be "when I grow up."
That question, "What are you going to be when you grow up?" continues to haunt me as time rushes past. At least I have the doctor part down; now to narrow things down a little. It certainly doesn't help going into residency applications and interviews with multiple fields of interest and no geographical preference. There are simply too many places, professions, and programs to choose from.
Some aids I have found include the specialty flowchart, the University of Virginia's Medical Specialty Aptitude Test (MSAT), and The Ultimate Guide to Choosing a Medical Specialty. There are days when I agree with their advice and other days I think they are in left field. What have you found useful in making your decision?

Women Who Suffer Migraine With Aura Have Better Outcomes After Stroke

Article Date: 01 Dec 2010 - 2:00 PST

Women with a history of migraine headache with aura (transient neurological symptoms, mostly visual impairments) are at increased risk of stroke. However, according to new research reported in Circulation: Journal of the American Heart Association stroke events in women with migraine with aura are more likely to have mild or no disability compared to those without migraine.

In a new analysis of the Women's Health Study involving 27,852 women over 13.5 years, researchers found those who have migraine with aura and who experience an ischemic stroke were twice as likely to have no significant disability from stroke.

"The message from this study should be reassuring for migraineurs," said Tobias Kurth, M.D., Sc.D., the study's principal author and associate epidemiologist at Brigham and Women's Hospital in Boston, Mass.

"It is important for women who have migraine with aura to know that their risk of stroke is considerably low and there is high likelihood of a migraine-associated stroke being mild."

The reason for these results is unclear. But Kurth, who is also director of research at INSERM in Paris, France, speculated that mechanisms, perhaps involving smaller vessels - not the traditional mechanisms for stroke, lead to a smaller size stroke.

Compared to those without migraine history, women with migraine and aura were more likely to have a good to excellent functional outcome - defined as having no symptoms and no significant disability, researchers said.

Women participating in the study were divided into four groups: 22,723 who reported no migraine history; 5,129 who reported a migraine history; 3,612 who had active migraine; and of those who reported active migraine, 1,435 reported active migraine with aura.

Researchers evaluated functional ability after stroke at hospital discharge using the modified Rankin Scale, a seven-point scale that measures degree of impairment.

At the onset of the study, women completed a questionnaire about their headaches that allowed classification into the groups of migraine with and without aura, history of migraine or no history of migraine. Each following year, the women reported new medical conditions, including transient ischemic attack (TIA) or stroke, which were confirmed after medical record review.

During 13.5 years of follow-up, 398 TIAs and 345 ischemic strokes occurred.

Women in the study were primarily Caucasian, average age 55, healthy and working in the healthcare field.

There is currently little reason to believe that the association differs for women with other characteristics or men, Kurth said.

The first author is Pamela M. Rist, M.Sc., a doctoral student at the Harvard School of Public Health and research fellow at Brigham and Women's Hospital. Other co-authors are: Julie E. Buring, Sc.D.; Carlos S. Kase, M.D.; Markus Schurks, M.D., M.Sc. Author disclosures are on the manuscript.

The Women's Health Study is supported by grants from the National Heart, Lung, and Blood Institute and the National Cancer Institute. Grants from the Donald W. Reynolds, Leducq and Doris Duke Charitable foundations funded part of the study.

Protein in the Urine: A Warning Sign for Cognitive Decline

 Released: 11/10/2010 3:00 PM EST
Embargo expired: 11/20/2010 9:15 PM EST

1. Small Amounts of Urinary Protein Predict More Rapid Cognitive Decline in Elderly Women
Screening Efforts in Older Individuals May Be Warranted
A new study has found that low amounts of albumin in the urine, at levels not traditionally considered clinically significant, strongly predict faster cognitive decline in older women. The study involved more than 1,200 women aged >70 years in the Nurses' Health Study who were phoned every two years for three cycles and tested for general cognition, verbal/word memory, verbal fluency (speed in making word associations), and working/short-term memory. Julie Lin, MD (Brigham and Women’s Hospital) and her colleagues found that participants with a urinary albumin-to-creatinine ratio of >5 mcg/mg at the start of the study experienced cognitive decline at a rate 2 to 7 times faster in all cognitive measures than that attributed to aging alone over an average 6 years of follow-up. “The strongest association was seen with a decline in the verbal fluency score, which has been attributed to progressive small vessel disease in the brain, which supports the view that albuminuria is an early marker of diffuse vascular disease,” said Dr. Lin. “Therefore, in light of the aging U.S. population, which is at risk for cognitive decline and vascular disease, simple, non-invasive screening for albumin in the urine as an independent predictor for subsequent cognitive decline may represent an important public health issue.”
Study co-authors include Fran Grodstein, PhD, Jae Hee Kang, PhD, and Gary Curhan, MD, ScD, (Brigham and Women's Hospital).
Disclosures: Dr. Curhan is a consultant for Takeda Pharmaceuticals; receives grants/research support from Astellas and honoraria from Takeda Pharmaceuticals. Dr. Lin, Dr. Grodstein, and Dr. Hee Kang reported no other financial disclosures.
The study abstract, “A Prospective Study of Albuminuria and Cognitive Decline in Women,” [SA-FC355] will be presented as an oral presentation on Saturday, November 20 Day, Date at 5:18 PM MT in Room 405 of the Colorado Convention Center in Denver, CO.
2. Urinary Protein Excretion Increases Risk of Cognitive Impairment
Simple Urine Tests Could Identify Individuals at Risk
Two characteristics of kidney disease—excreting protein in the urine (albuminuria) and low kidney function—increase individuals’ risk of becoming confused and forgetful. To see whether these two characteristics are related or independent in their effects on cognitive decline, Manjula Kurella Tamura, MD (Stanford University) and her colleagues studied clinical data from 19,399 individuals participating in the Renal Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. A total of 1,184 participants (6.1%) developed cognitive impairment over an average follow-up of 3.8 years. Individuals with albuminuria were 1.31-1.57 times more likely to develop cognitive impairment compared to individuals without albuminuria. This association was strongest for individuals with normal kidney function (eGFR ≥60 ml/min/1.73m2) and attenuated among individuals with low levels of kidney function. Conversely, low kidney function (eGFR <60 ml/min/1.73m2) was associated with a higher risk for developing cognitive impairment only among individuals without albuminuria. Surprisingly, individuals with albuminuria and normal kidney function had a higher probability for developing cognitive impairment as compared to individuals with moderate reductions in kidney function (eGFR 45-59 ml/min/1.73m2) in the absence of albuminuria. The findings indicate that the presence of protein in the urine, even in small amounts, could be a warning sign that a patient may later have difficulty thinking clearly. “The results are important because albuminuria is easily measured and potentially modifiable. Incorporating information about albuminuria along with kidney function should help clinicians identify patients at high risk for subsequent cognitive decline and dementia,” said Dr. Kurella Tamura.

'Doctor, Are You Telling Me the Truth?' Exclusive Ethics Survey Results

Shelly M. Reese.
Posted: 11/30/2010.

"Honesty is the best policy" and "the patient always comes first."
As absolute and correct as those aphorisms may be, they can be hard for doctors to apply in the complex world of modern medicine.
A recent Medscape medical ethics survey of over 10,000 physicians found that when it comes to patient treatment, a significant number of physicians struggle when it comes to topics relating to honest, straight-forward communication, and even pain management. Physicians from a broad range of specialties answered 3 questions pertaining to patient treatment:
-     Would you ever hide information from a patient about a terminal or preterminal diagnosis, because you believe that it will bolster their spirit or attitude?
-      Would you ever prescribe a treatment that's a placebo, simply because the patient wanted treatment?
-      Would you ever undertreat a patient's pain, because of a fear of repercussions or because you are concerned that a patient -- even a terminal patient -- might become addicted?

Open Communication Is Often Difficult

When it comes to delivering bad news, 59.8% of physicians indicate they "tell it exactly as I see it," while 14.6% indicate that they soften the news and "give hope even if there is little chance." Two percent indicate that unless a patient is going to die imminently, they don't tell him or her how bad the situation is and nearly one quarter (23.8%) say "it depends."
"The kind of compassion that brings people into medicine is the type of compassion that is needed for delivering bad news," says Kenneth Goodman, PhD, Director of the Bioethics Program at the University of Miami and author of Ethics and Evidence-Based Medicine: Fallibility and Responsibility in Clinical Medicine. But that compassion should never compromise the truth, he cautions.
Many of the physicians surveyed augmented their responses noting that, while they are honest, they try hard to deliver bad news in the most gentle, humane, and supportive way possible. That's exactly what patients should expect from their doctors, Goodman advises. But in "softening" the truth, he believes that doctors don't need to deviate from it.
"If there is something positive you can say, by all means say it. But only tell the truth: 'I will be there with you. I will help you manage your pain. I will see to it that you can arrange your affairs.' Those are truthful things," Goodman says.
When doctors withhold information, they make it more difficult for patients to chart their course and undermine their own credibility.
From the patient's point of view, "If I don't know my time is limited I can't put my affairs in order. I can't say, 'I'm sorry,'" he says. What's more, "it's not like patients are asking Dr. Kildare, 'What are my chances, Doc?' Patients are increasingly educated. If you don't tell them, they're going to be looking it up on the internet the next day, so you should probably be the source of the data, because you're a human and you care about them."


Goodman advises that the same rationale applies to the use of placebos. Nearly one quarter (23.5%) of respondents said they would prescribe a treatment that was essentially a placebo to a patient simply because he or she wanted treatment. Another 18.2% said, "It depends."
Physicians who were willing to provide "placebo" treatment generally fell into 2 camps. Some said they would do it to appease a patient but only after telling them it wouldn't do them any good. One doctor noted that he'd prescribe vitamins and supplements, "but I'd tell them I thought it was worthless"; while another would prescribe a cream for hemorrhoids, "but they are also forewarned" that the treatment wouldn't do any good.
Still another noted, "In this day and age, many patients will not accept that the best treatment is tincture of time and they have no hesitation about reporting you to the state board or hospital administrator. So, I figure out something that will do the least potential harm and try that."
Others say they'd be willing to prescribe a benign but ineffectual treatment in hopes of achieving a positive placebo effect. "Placebo works up to 50% of the time," said one. "Placebos ARE a form of treatment!" noted another and, "Placebo can be psychologically beneficial and I don't see that as placebo," wrote a third.
Physicians in the first group need to be able to stand their ground in the face of insistent patients, Goodman advises. After all, they are the medical experts.
"Doctors need to be able to say, 'I'm sorry, there is nothing I can do,' No physician is going to provide drugs for a recreational purpose. Why, if a patient asks for an antibiotic for a virus or a prescription that won't work, should he get it?" Goodman asks. As for those hoping to achieve a placebo effect he notes, if a patient finds out he or she has been prescribed a placebo, it will cause irrevocable damage to the physician-patient relationship.

Pain Management Quandaries

While the first 2 patient treatment questions in the survey pertained to communication, the last addressed pain management. While the overwhelming majority (84.1%) of physicians said they would never undertreat pain, a handful (5.6%) said they would, and about 1 in 10 (10.3%) said they would have to evaluate the situation before making a decision.
After filtering out responses from physicians – many of them emergency department doctors – noting that they routinely deny drug-seeking "frequent fliers" prescriptions for pharmaceuticals, the theme frequently voiced by doctors was that they would undertreat pain due to fear of lawsuits. A number of respondents augmented their answers with frustrated, emotional responses about state medical boards, government intrusion, and litigious patients.
Comments included: "I undertreat not due to concerns about addiction but concerns about Drug Enforcement." "We live in a real world. I would like to think I would answer 'no' if real tort reform took place." "I bet we all would in today's drug-abusing, litigious society." And "The state boards can wreck a doctor without appeal."
Despite those concerns, others remained steadfast. "I have only the patient to believe as to how much pain they are experiencing. I have been lied to at times over the years, but I would rather try to believe people than to deny everyone because of some bad actors," wrote one.

When Treatment Denial Causes Suffering

Another noted that physicians' fears of repercussions have "caused patients to suffer needless pain. If a physician does not feel competent or comfortable handling pain issues, (s)he should refer that patient to a reputable pain specialist. Pain is a legitimate medical condition, which we took an oath to alleviate when possible. If the treatment is appropriate and well documented with the current safeguards in place, there should be no fear."
Most respondents who elaborated on their answers, however, drew a sharp distinction between patients with chronic conditions and the terminally ill. Many noted that they do not prescribe narcotics to patients with chronic conditions, refer them to pain management specialists, and are vigilant when it comes to chronically ill patients who tend to "lose" prescriptions too often. When it comes to treating the terminally ill, however, respondents spoke in a single voice: treat their pain.
"Terminal patients should be able to get whatever they need whenever they need it," wrote one. "Terminal patients get whatever they need," said another. A third noted, "Terminal patients should never be allowed to suffer with pain because of inadequate treatment, especially fear of addiction: what difference does it make if they are going to die addicted to narcotics?"

Never Stop Learning

Kendra Campbell, MD, Psychiatry/Mental Health, 02:51PM Dec 4, 2010

 

"Cultivate the society of the young, remain interested, and never stop learning." -- Marcus Tullius Cicero

I’ve always been intrigued by learning new things. I believe that my spark for learning was ignited by my phenomenal parents. Some of the first memories I have as a child are of my parents taking the family on hikes through the Shenandoah National Park in Virginia. I remember my mother pointing out interesting looking flowers and trees, naming their genera and species, and sharing with us fascinating tidbits about them. When I was a child, we had very little access to television, and I can recall complaining to my father, “dad, I’m bored!” He would frequently respond with, “then go read the encyclopedia.” I would walk up to the shelf of encyclopedias, pick a random letter off the shelf and read everything there was to know about things that started with the letter “K.” (Ahhh, life before Wikipedia!)
Although I have about 19 years of formal education under my belt, there’s still so much about the world that I don’t know and don’t understand. But my hunger to learn about the world around me continues to drive me to seek out more opportunities and experiences.
Before I truly understood what being a doctor was all about, I thought that medical school was the golden mecca. In my ignorance, I believed that medical school was where you learned how to be a doctor. How very wrong I was! 
When I first started residency, I thought, “okay, this is where I will really become a doctor...where I will learn all there is to know about my specialty.” Well, it turns out that I was wrong again!
The lesson that I’ve discovered is that being an excellent physician truly means being a lifelong learner. You will never know everything. And the pace at which we are making new discoveries ensures that if you stop reading, you will quickly be “behind the times.” 
But it’s not just about keeping up with all the new scientific facts and discoveries, it’s actually quite a bit more complicated than that. To be a great healer, one must never stop listening to their patients. One must continue to see each patient as an opportunity to learn something new about people, how to heal them, and how to heal oneself.
Now that I’m a resident, I am in the unique and extraordinary position of being both a student and a teacher. I learn something new every day from my patients, the nurses, and the attendings. But I also get to impart some knowledge to the upcoming batch of doctors. 
A few days ago, I had a medical student tell me that she had learned many skills from me, which she would carry with her for the rest of her medical career. This was a momentous reminder to me of the power and gift that is teaching. 
I think the philosopher and writer, Jiddu Krishnamurti put it well: 
"There is no end to education. It is not that you read a book, pass an examination, and finish with the education. The whole of life, from the moment you are born to the moment you die, is a process of learning."

Experiencing Happiness as a Medical Student











Joshua Batt, Medical Student, 03:39PM Dec 5, 2010

 Is your happiness conditional? Do we delay the experience of feeling happy until we have achieved the next step? At one time happiness was conditional on getting into medical school, next was passing the boards, then it is graduating medical school and finally when we become an attending...then we will be happy. What is wrong with being happy now in the role we fill today?

Srikumar Rao's recent discourse, "Plug Into Your Hard Wired Happiness," really drives home the point that we can enjoy life as it is without setting emotional pleasure aside to await a measurable outcome. He encourages investing not only in the outcome, but also in the process. Unfortunately, we are focused too often on the end goal without seeing the smaller steps before us, whether we fail or succeed.
This principle can be easily applied to life as a medical student. We strive every day to choose the right answers on exams, please our clinical professors, and learn extensive amounts of information for future use. There will be many times when we fall short of an errorless performance. If we recognize the role we are playing now as students, we will make the progress needed to obtain the final outcome we all had in mind at the beginning. Invest in the process and enjoy the journey, it is just as important as the end product.
I love being a medical student. It pushes me to explore my interpersonal, critical thinking, and knowledge based skills. I have made my fair share of mistakes on exams and with my clinical preceptors. Like a child experiencing something for the first time, it is still a wonderful exploration of who I am and who I want to be, despite the difficulties. Don't wait until the end to experience happiness; you might just put it off again. Find ways to be happy every day, even when the going gets tough.

Science Explains Why Breaking Up Is Hard to Do


Helen Fisher, a biological anthropologist at Rutgers University in New Brunswick, New Jersey, knows all about love. She has observed the brain regions associated with romantic love light up as a man gazes at his inamorata, both in new relationships and in decades-long marriages. Fisher seems to have become a bit jaded by years of Hallmark moments, however. “Who cares about people who are happily in love?” she wants to know. “It’s when you’ve been rejected that you turn into a menace.” So she has started exploring the science of heartbreak instead.
In a study published in May, Fisher and her colleagues asked 15 people who had recently been dumped but were still in love to consider two pictures—one of the former partner and one of a neutral acquaintance—while an MRI scanner measured their brain activity. When looking at their exes, the spurned lovers showed activity in parts of the brain’s reward system, just as happy lovers do. But the neural pathways associated with cravings and addictions were activated too, as was a brain region associated with the distress that accompanies physical pain.
Rejected lovers also showed increased neural response in regions involved in assessing behavior and controlling emotions. “These people were working on the problem, thinking, what did I do, what should I do next, what did I learn from this,” Fisher says. And the longer ago the breakup was, the weaker the activity in the attachment-linked region. In other words: Love hurts, but time heals.

How Can Leg Cramps Be Treated?

Jodi H. Walker, PharmD
Adjunct Faculty, Albany College of Pharmacy, Albany, New York; Clinical Pharmacy Coordinator, VA Medical Center, Bath, New YorkPosted: 06/14/2010


Idiopathic leg cramps are presenting more and more frequently in the healthcare community. Leg cramps have historically been underreported. However, as patients become increasingly informed through television and the Internet and become aware of such conditions as the restless legs syndrome, treating leg cramps is a common issue facing healthcare providers today.
Although quinine sulfate has been shown to be efficacious in treating leg cramps, the Food and Drug Administration (FDA) banned over-the-counter use in 1994 due to risk for potentially fatal hypersensitivity reactions, thrombocytopenia, and cardiac arrhythmia.[1] In 2006, the FDA banned marketing of unapproved prescription quinine products.[2] Quinine remains available by prescription for treatment of malaria, but its risks as a preventive or treatment for leg cramps outweigh any potential benefit.[2]
Nonpharmacologic therapy is not well-established but may warrant an initial trial before treatment with medication. Hydration, warm or cold compresses, exercising, or calf stretches may provide some benefit.[3]
Although no specific medical treatment is indicated for leg cramps, several drugs have been used with varied success. Calcium-channel blockers, such as diltiazem, have been used to treat nocturnal leg cramps. Vitamin B complex (including 30-mg vitamin B6) has also shown effectiveness.[4]
Patients with chronic leg cramps should consult with their healthcare provider to investigate underlying causes. A differential diagnosis is important when patients with leg cramps are being examined, because many disorders, such as tetany, myalgia, the restless legs syndrome, and peripheral vascular disease, can have symptoms that present as leg cramps.[3]
Quinine continues to be used off-label to treat nocturnal leg cramps; however, an FDA postmarketing review states that there are no reliable data to support its use, and although it is often effective, serious adverse effects have occurred.[2] The American Academy of Neurology systematically reviewed the available evidence on symptomatic treatment of muscle cramps and their recommendations include the following[4]:
  • Consider vitamin B complex or calcium-channel blockers, such as diltiazem.
  • Avoid routine use of quinine.
  • Potentially consider quinine for an individual trial once side effects are evaluated; side effects must be carefully monitored.

Doctors Claim HIV-Positive Patient Cured by Stem Cells

German doctors announced what could be ground-breaking news in the fight against HIV and AIDS. An HIV-positive patient, who had developed acute myeloid leukemia, is said to have been cured of his HIV infection after a bone marrow transplant, which was performed in 2007.

The 'Berlin Patient,' a U.S. citizen named Timothy Ray Brown, underwent a procedure in which HIV-resistant stem cells from an individual with an unusual genetic profile were introduced into his body. The donor patient's CD4 cells lacked the CCR5 co-receptor -- the most common variety of HIV uses CCR5 co-receptors as a "docking station," attaching to it in order to enter and infect CD4 cells. People with this particular genetic mutation are almost completely protected against infection.

Brown underwent grueling treatment for leukemia, two stem cell transplants and also suffered from a serious neurological disorder, which required a brain biopsy. Before the stem cell transplant he received chemotherapy treatment that destroyed most of his immune cells, as well as total body irradiation and received immunosuppressive drugs to prevent rejection of the stem cells. After all of this, HIV was undetectable by both viral load testing (RNA) and tests for viral DNA within cells.

In an interview with the German news magazine, Stern, Brown was asked if might have just decided to live with HIV rather than undergo this lengthy and difficult process. "Perhaps," he answered. "Perhaps it would have been better, but I don't ask those sorts of questions anymore."

Berlin doctors published his detailed case history in the New England Journal of Medicine in February 2009. Now they've published a follow-up report in the journal Blood, saying: "It is reasonable to conclude that cure of HIV infection has been achieved in this patient."

The revelations about the 'Berlin Patient' point to the fact that a cure for HIV could be developed using genetically engineered stem cells. NAM Aidsmap reports that the German researchers and San Francisco-based immunologist Professor Jay Levy are stressing the importance of suppressing CCR5-bearing cells, either through transplants or gene therapy.

Dr. David J. Ores, a general practitioner on the Lower East Side of Manhattan says that while the thought of a cure for HIV is appealing, he's not sure if this one case is the answer.

"This patient has many unique factors," Ores told AOL Health. "He had leukemia. Twice. He had all sorts of chemotherapy and radiation. Twice. His genetics are unique to himself (like anyone else). The HIV could be dormant for now. We also don't know which sub-type of HIV he had. Or if he had other infections in the past which effect his immune system."

Ores goes so far as to question whether the 'Berlin Patient' actually had HIV in the first place. "Maybe his leukemia affected the HIV test since HIV is, in fact, leukemia as well. Recall, HIV was originally classified as 'HTLV type one' which stands for Human T-Cell Leukemia Virus (HTLV). So maybe his other leukemia affected the test for the other HIV leukemia (HIV)."

Still, Ores says that if the research is indeed valid, any advancements it creates toward finding a cure would be a positive thing.

Last year, several US research groups announced they had received funding to explore the development and implantation of CCR-5 deficient stem cells.

But even if these techniques prove to be successful, they will no doubt be very expensive, meaning that they would be reserved for people with no treatment options left, or cancer patients already requiring a bone marrow transplant.

The 'Berlin Patient's' road to recovery was not an easy one -- he endured chemotherapy, immunosuppresive drugs and stem cell transplants -- but in the end, his tough journey could pave the way for advancements toward an eventual cure for HIV that all people can benefit from.

Estrogen Alone is Effective for Reducing Breast Cancer Risk

Newswise — SAN ANTONIO — While endogenous estrogen (i.e., estrogen produced by ovaries and by other tissues) does have a well-known carcinogenic impact, hormone replacement therapy (HRT) utilizing estrogen alone (the exogenous estrogen) provides a protective effect in reducing breast cancer risk, according to study results presented at the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 8-12. 

“Our analysis suggests that, contrary to previous thinking, there is substantial value in bringing HRT with estrogen alone to the guidelines. The data show that for selected women it is not only safe, but potentially beneficial for breast cancer, as well as for many other aspects of women’s health,” said lead researcher Joseph Ragaz, M.D., medical oncologist and clinical professor in the faculty of medicine, School of Population and Public Health at The University of British Columbia, Vancouver, BC, Canada.

“These findings should intensify new research into its role as a protective agent against breast cancer,” he added.

Ragaz and colleagues reviewed and reanalyzed data from the Women’s Health Initiative (WHI) hormone replacement therapy trials. WHI is a national health study that focuses on strategies for preventing heart disease, breast and colorectal cancer, and fracture in postmenopausal women. The WHI was launched in 1991 and includes more than 161,000 U.S. women aged 50 to 79 years. 

“Over the last 30 years HRT has been used almost indiscriminately by women expecting the benefit of reducing cardiac risks, while providing a protective effect against bone fracture, and improving overall quality of life,” said Ragaz. “The WHI results as originally interpreted led to a major pendulum swing against HRT.”
The WHI HRT trial consisted of two cohorts of women; the estrogen-alone group of women without a uterus and the estrogen-plus-progestin group of women with a uterus. 

Ragaz and colleagues reanalyzed the WHI studies in more detail and found that subsets of women with no strong family history of breast cancer who received estrogen alone had a significantly reduced breast cancer incidence. In addition, the 75 percent of women without benign disease prior to the trial enrollment also had a reduced breast cancer risk. 

“Reduction of rates of breast cancer in the majority of women who are candidates for estrogen-based HRT is a new finding because estrogen was always linked with a higher incidence of breast cancer,” Ragaz said, “yet estrogen administered exogenously is actually protective for most women.”

Based on the results of this current analysis, Ragaz suggested that “while the use of HRT with estrogen alone may reduce the risk of breast cancer and may also be appropriate to manage menopausal symptoms, further research is warranted to elaborate on the optimum treatment regimen, to refine the selection of ideal candidates for estrogen therapy, and to understand the estrogen mechanisms that support the prevention of human breast cancer.” 

“The recommendations based on prior analyses of the results of the WHI HRT studies was not to use HRT, but we are optimistic this will change,” he said. “Our conclusion, based on the data presented, should enhance considerations for an early approval of HRT based on estrogen-alone for the majority of selected women suffering with menopausal symptoms and galvanize new research on HRT to define the optimum regimens for individual women.”

WOMEN, DEPRESSION AND OBESITY: WHAT'S EATING YOU?


Washington, DC (December 14, 2010) — The Society for Women’s Health Research (SWHR) presented the topical Capitol Hill briefing, Holiday Blues: Women, Depression and Obesity on Thursday, December 9, which featured four panelists detailing the links between depression and obesity.

Obesity is the newest health threat due in large part to American’s sedentary lifestyle and poor food choices. Co-morbidities of obesity include depression, heart disease, stroke, type II diabetes, hypertension, some cancers, osteoporosis and more. Sex differences in obesity play a role in fat distribution, higher financial burden on women, and incidence rates. According to the Centers for Disease Control, in 2008 33.2% of females were obese, with a body-mass index (BMI) of 30 or higher.

Belinda Needham, PhD, Assistant Professor and Director of Graduate Studies at the University of Alabama at Birmingham, spoke to the effects of obesity and depression, “17% of women will experience serious depression; females are two times as likely to be depressed as males, and women gain weight faster than men.” Needham presented findings from a community study to gauge the effects of obesity on depression and discovered women had higher BMIs at the start of the study and ended up larger than men at the end of the study. She concluded that depression led to weight gain and not the other way around.

“Elevated depressive symptoms affect over 25% of adolescents, and adolescent girls with elevated depressive symptoms are 2.5 times more likely to develop obesity at a later point in time compared to girls without depressive symptoms,” said Lauren B. Shomaker, PhD, Adjunct Scientist in the Unit on Growth and Obesity, National Institute of Child Health and Human Development. “Depressive symptoms lead to an increase in stress-induced eating, which results in obesity. And depression is theorized to alter physical fitness by a loss of pleasure in previously enjoyed physical activities.”

Fortunately, there are researchers leading studies to reverse this trend. Jay Breines, Executive Director, Holyoke Health Center, launched a pilot program at his health center in Holyoke, Mass. to combat obesity and teach proper nutrition and exercise habits to high-risk populations. His program integrated physicians, dentists, nurses, outreach workers, and promotoras among many others to provide a full care team for the participants to fight obesity and stop depression from taking hold. Breines closed with an advisory message to fellow community health organizers battling obesity, “We must engage at the community level to save money on our healthcare system.”

Christine Ferguson, Director, STOP Obesity Alliance and Research Professor, George Washington University School of Public Health and Health Services, outlined the obesity cost burden. Ferguson’s research team found the overall annual costs of being obese are $4879 for an obese woman and $2646 for an obese man. “There is a real, tangible economic impact for those women who are obese in our society,” said Ferguson. Obese women are paid less than average-weight women whereas obese men are paid the same as average-weight men. This can be partly attributed to social stigmatization and the already present gender wage gap.

“The key to obesity policy is to relate more to the health aspect, and less the aesthetic,” said Ferguson. Focusing on health versus looks may decrease depression and boost self-esteem. We need to support programs that target adolescents and teach healthy lifestyle habits in order to stave off depression as well as obesity.

Depression may lead to weight gain and vice versa, thus treatment for either should target both mind and body. Properly training physicians on weight-related issues, providing health and nutrition centers in high-risk communities, and focusing on the health aspects of obesity are just a few more ways to fight the fat and, in turn, defeat depression this holiday season and beyond.

SPINA BIFIDA: HOW TO PROTECT YOURSELF AND YOUR BABY


Jennifer Wider, MD
SWHR Contributing Writer
October 25, 2010

October marks National Spina Bifida Awareness Month, a condition that affects thousands of American babies each year.

Spina Bifida is a birth defect caused by the incomplete closing of the neural tube during embryonic development. The neural tube is a structure that ultimately forms the baby’s brain and spinal cord and their surrounding tissues. In normal fetal development, the neural tube forms early on in pregnancy and closes several weeks thereafter. In babies with Spina Bifida, a portion of the tube fails to close properly, which can lead to defects in the back bone and spinal cord.

According to statistics from the Spina Bifida Association of America (SBAA), Spina Bifida is the most common, permanently disabling birth defect in the United States. Every day, roughly eight babies are born with Spina Bifida or a related birth defect in this country.

While the exact cause of Spina Bifida is not entirely known, there are several recognized risk factors. According to information from the Mayo Clinic’s Foundation for Education and Research, the following are the most common risk factors:
  • Family history: Women who have given birth to one child with a neural tube abnormality seem to have a higher risk of occurrence in subsequent children.
  • Race: Spina Bifida seems to more common in Caucasian and Hispanic populations.
  • Folic Acid deficiency: A nutritional deficiency of folate (or folic acid), vitamin B9, increases the risk of Spina Bifida and many other neural tube defects.
  • Certain medications: Research studies have shown that certain drugs including anti-seizure medications may interfere in the body’s ability to utilize folic acid and can lead to an increase in neural tube problems.
  • Obesity: Women who are obese prior to and during their pregnancies have a higher risk for Spina Bifida and other known neural tube deformities.
While some of the risk factors cannot be controlled, others including diet and vitamin supplements clearly make a difference. “Folic acid dietary supplementation appears to reduce the occurrence of Spina Bifida and other neural tube defects,” explains William Graf, MD, Director of the Yale/New Haven Hospital Spina Bifida Program in Connecticut. “Clinicians in the United States should advise women without a family history of NTDs (neural tube defects), who anticipate a pregnancy to take .4-.8 mg (400-800 micrograms) of folic acid daily.”

According to data from the SBAA, “if all women who could possibly become pregnant were to take a multivitamin with folic acid, the risk of neural tube defects like Spina Bifida could be reduced by up to 70 percent.” Because many pregnancies are unplanned, most experts recommend women in their childbearing years to take the recommended dose of 400 micrograms of folic acid. Folic acid can be found in foods including: dark, green leafy vegetables, whole wheat products, nuts and seeds, oranges, grapefruits and fortified cereals and grains.

It is important for women to realize the cause of Spina Bifida is not clearly understood and most likely results from an interplay of many factors, including: nutritional, environmental and genetic. According to Dr. Graf, “there has been a slight miscommunication that folic acid will completely prevent this very complex, early neurodevelopmental disorder.” Thus, if a woman has a family or personal history of neural tube defects, it is important she speaks to her health care provider about how to further reduce the risk for her offspring.

2010 AHA Guidelines: The ABCs of CPR Rearranged to "CAB"

News Author: Emma Hitt, PhD
CME Author: Laurie Barclay, MD

CME/CE Released: 10/27/2010; Valid for credit through 10/27/2011.

October 20, 2010 — Chest compressions should be the first step in addressing cardiac arrest. Therefore, the American Heart Association (AHA) now recommends that the A-B-Cs (Airway-Breathing-Compressions) of cardiopulmonary resuscitation (CPR) be changed to C-A-B (Compressions-Airway-Breathing).

The changes were documented in the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, published in the November 2 supplemental issue of Circulation: Journal of the American Heart Association, and represent an update to previous guidelines issued in 2005.

"The 2010 AHA Guidelines for CPR and ECC [Emergency Cardiovascular Care] are based on the most current and comprehensive review of resuscitation literature ever published," note the authors in the executive summary. The new research includes information from "356 resuscitation experts from 29 countries who reviewed, analyzed, evaluated, debated, and discussed research and hypotheses through in-person meetings, teleconferences, and online sessions ('webinars') during the 36-month period before the 2010 Consensus Conference."

According to the AHA, chest compressions should be started immediately on anyone who is unresponsive and is not breathing normally. Oxygen will be present in the lungs and bloodstream within the first few minutes, so initiating chest compressions first will facilitate distribution of that oxygen into the brain and heart sooner. Previously, starting with "A" (airway) rather than "C" (compressions) caused significant delays of approximately 30 seconds.

"For more than 40 years, CPR training has emphasized the ABCs of CPR, which instructed people to open a victim's airway by tilting their head back, pinching the nose and breathing into the victim's mouth, and only then giving chest compressions," noted Michael R. Sayre, MD, coauthor and chairman of the AHA's Emergency Cardiovascular Care Committee, in an AHA written release. "This approach was causing significant delays in starting chest compressions, which are essential for keeping oxygen-rich blood circulating through the body," he added.

The new guidelines also recommend that during CPR, rescuers increase the speed of chest compressions to a rate of at least 100 times a minute. In addition, compressions should be made more deeply into the chest, to a depth of at least 2 inches in adults and children and 1.5 inches in infants.

Persons performing CPR should also avoid leaning on the chest so that it can return to its starting position, and compression should be continued as long as possible without the use of excessive ventilation.
9-1-1 centers are now directed to deliver instructions assertively so that chest compressions can be started when cardiac arrest is suspected.

The new guidelines also recommend more strongly that dispatchers instruct untrained lay rescuers to provide Hands-Only CPR (chest compression only) for adults who are unresponsive, with no breathing or no normal breathing.

Other Key Recommendations
Other key recommendations for healthcare professionals performing CPR include the following:
  • Effective teamwork techniques should be learned and practiced regularly.
  • Quantitative waveform capnography, used to measure carbon dioxide output, should be used to confirm intubation and monitor CPR quality.
  • Therapeutic hypothermia should be part of an overall interdisciplinary system of care after resuscitation from cardiac arrest.
  • Atropine is no longer recommended for routine use in managing and treating pulseless electrical activity or asystole.
Pediatric advanced life support guidelines emphasize organizing care around 2-minute periods of continuous CPR. The new guidelines also discuss resuscitation of infants and children with various congenital heart diseases and pulmonary hypertension.

The authors of the guidelines have disclosed no relevant financial relationships.

Assessing the Lower Extremities in the Geriatric Patient

Mark E. Williams, MD
Posted: 11/08/2010

Overview

This presentation is primarily concerned with the orthopaedic and vascular aspects of the lower extremity examination, with a focus on the legs. For more detailed information on assessing the feet, see Evaluating Foot Pain in Elderly Patients . The assessment of balance and gait and the neurologic evaluation of the lower extremities are beyond the scope of this presentation.

Assessment of the Hip in the Geriatric Patient

General Evaluation of the Hip

Observations of standing posture. The hip cannot be inspected or palpated directly; therefore, most inferences derive from changes in movement. Observe the patient's standing posture because hip problems will tend to cause the affected foot to advance slightly and rotate slightly inward. Also check Trendelenburg's sign; have the patient lift the right leg and observe whether the left hip elevates, which is normal, or does not (a positive test). Repeat on the other side. A positive test suggests degenerative joint disease, weakness of the gluteus, or hip dislocation. Seeing a compensatory lordosis when the hip is extended suggests a fixed flexion deformity of the hip. You can confirm your impression with Thomas' Test below.
Thomas' Test for Fixed Flexion Deformity of the Hip
First check for lumbar lordosis. With the patient lying supine, try to place your left hand, palm up, between the patient's low back and the table. If your hand is able to be inserted between the back and the table then the patient has a lumbar lordosis. If not, then the deformity is not present
Next, ask the patient to flex the normal leg and pull it to the chest. If there is no fixed flexion deformity, the opposite outstretched leg will remain on the table. If the deformity is present, pelvic rotation as the normal leg is flexed will cause the opposite leg to rise off the examination table.

Hip range of motion. Next, perform the hip isolation test to observe the range of motion. With the patient prone, flex the knee to about 90° and move the foot medially and laterally so that the knee also swings medially and laterally. Limited range of motion implies degenerative joint disease of the hip. This test isolates the hip so that extra-articular causes of discomfort are minimized.

Hip Pain After a Fall

First, inspect the leg. Consider the following:
  • If it is foreshortened and externally rotated, consider fracture below the femoral neck (intertrochanteric fracture);
  • If the leg is externally rotated but not foreshortened, consider fracture of the femoral shaft;
  • If the thigh is externally rotated, flexed, and abducted, consider anterior dislocation; and
  • If the thigh is internally rotated and adducted with a very prominent greater trochanter, consider posterior dislocation.
Now check for fracture with the use of osteophony (Hueter's sign). This test is extremely helpful in evaluating patients during home visits or in the nursing home. Place the diaphragm of your stethoscope on the pubic symphysis. Gently percuss each kneecap with your forefinger. An intact bone will produce a clear, bright tapping sound. A hip fracture will give a muffled, distant sound. Other approaches use a tuning fork on the patella or listening over each iliac crest as opposed to the pubic symphysis.

Chronic Hip Pain or Decreased Range of Motion

As you perform this assessment, keep in mind the possibility of referred pain from the knee (see below).
Patrick's test. To perform Patrick's test, place the patient's ankle on the contralateral knee and then gently press down on the flexed knee. Pain in the hip suggests osteoarthritis of the hip; pain radiating from the back down the leg suggests radiculopathy; and pain in the lower spine suggests compression fracture.
Laguerre's test. With the patient supine, grasp the heel on the symptomatic side and passively flex the knee and hip and rotate the patient's hip. Pain over the greater trochanter suggests bursitis, whereas pain in the hip and groin suggests degenerative joint disease.
Trendelenburg's sign. Have the patient stand and transfer the weight to the nonpainful leg. If the painful buttock drops and becomes flaccid, suspect severe degenerative joint disease, weakness of the gluteus, or hip dislocation.
Palpate the anterior iliac spine. Palpate along the anterior iliac spine and inguinal ligament. Increasing dysesthesia along the anterior thigh indicates meralgia paresthetica.

Additional Hip Assessment Pearls

  • Feeling a crepitant sensation when palpating over a bone in the absence of infection suggests sarcoma (Dupuytren's sign); and
  • Flattening of the thigh when a patient lies supine suggests upper motor neuron disease (Heilbronner's sign).

General Evaluation of the Knee

It is normal for both the ankles and the knees to touch. Being knock-kneed (knees touch but ankles do not) involves a valgus deformity of the knee. Bow-leggedness (ankles touch but knees do not) is a varus deformity of the knee. If the knees curve backward in the lateral dimension, there is a genu recurvatum deformity. Osteoarthritis will produce bony enlargement, which is sometimes magnified by coincident quadricep muscle atrophy. Look for scars that indicate previous knee surgery.
Check knee range of motion. Observe passive knee range of motion by gently flexing and extending the knee with the patient sitting or supine. Decreased range of motion suggests degenerative joint disease. Increased lateral movement suggests damaged ligaments.
Check for crepitus. Check for crepitus in the knee joint by listening for the crunching, popping sound (or feeling) on joint movement. Finding no crepitus is normal. If crepitus is present, it suggests degenerative joint disease. The location defines the affected compartment, so that anterior, lateral, or medial crepitus suggests knee degenerative joint disease in those respective locations. Crepitus on extension suggests patellofemoral syndrome.
Check for effusion. Now search for knee effusion. Feel for a spongy movement of the patella and look for a bulge between the patella and the condyles. If there is any spongy downward movement of the patella when the leg is fully extended, then an effusion is present. In addition, you can milk the fluid from the medial side with your forefingers and middle fingers and then push with your thumbs from the lateral side just below the patella. Seeing a medial bulge (bulge sign) suggests effusion.
Check the tibial and femoral condyles positions. Tibial condyles displaced posteriorly to the femoral condyles suggest a prior posterior cruciate ligament tear. Tibial condyles displaced anteriorly to the femoral condyles suggest a prior anterior cruciate ligament tear.

Anterior Knee Pain

Check for bony deformity.
Check for effusion (vide supra). If present, patellar effusion will present as spongy ballottement, bulging of the joint, or a fluid wave. Check for tenderness and swelling over the quadriceps muscles. The presence of pain suggests quadriceps rupture or strain.
Check for patellar tenderness. Doughy swelling above the patella suggests suprapatellar bursitis (housemaid's knee). Swelling and tenderness on the patella suggest prepatellar bursitis (roofer's knee), usually brought on by constant kneeling. Marked tenderness and swelling over the patella suggest patellar fracture. Tenderness below the patella without swelling suggests tendonitis (jumper's knee). Swelling and tenderness below the patella suggest infrapatellar bursitis (pastor's knee).
Patellofemoral syndrome. Look for quadriceps atrophy, especially the vastus obliquus medialis. Also feel for tenderness behind the patella with palpation. Perform the patellar inhibition test. Stabilize the patella with your thumb and forefinger, and then gently try to push it toward the feet. Have the patient contract the quadriceps to move the patella upward. Pain and relaxation of the quadriceps is a positive test. Now move the patella medially and laterally with knee flexed to 30 degrees. Increased lateral mobility is a positive apprehension test. Voluntary contraction of the quadriceps when moving the patella laterally is also a positive test. Check for lateral patellar displacement with extension that resolves with flexion.

Pain Behind the Knee

Search for a popliteal mass. A nontender area of bogginess suggests a Baker's cyst. Feeling a pulsatile mass suggests popliteal artery aneurysm. Feeling a tender mass in the popliteal fossa suggests bursitis.
Look for focal or diffuse tenderness in the popliteal fossa. Focal tenderness in the medial popliteal fossa without a mass suggests a hamstring muscle strain. Diffuse tenderness and swelling suggest a ruptured Baker's cyst or deep venous thrombosis.

Medial Knee Pain

Palpate for tenderness. Check for an anatomic deformity and palpate the site of tenderness. Pain behind the knee suggests a hamstring tear. Exquisite tenderness medial and inferior to the tibial plateau suggests anserine bursitis. Tenderness midway between the femur and the tibia suggests medial collateral ligament damage. Tenderness anterior to the condyles suggests a medial meniscus tear.
Check for joint laxity. Now test for joint laxity with lateral movement. The degree of laxity defines the extent of medial collateral ligament tear. Pain in the lateral knee with this movement suggests lateral meniscus tear (Bohler's sign).
Check for meniscus tear. Employ McMurray's maneuver; with the patient supine, passively flex the knee until the heel hits the buttock. Rotate foot laterally and then extend the knee. A loud click over the lateral knee suggests a medial meniscus tear. Also check Apley's compression test. With the patient prone and the knee flexed to 90° (perpendicular to the examining table), push down and gently twist the foot. Pain or crepitus is a positive test. Payr's test is also useful. With the patient sitting cross-legged, push on the painful knee. Medial knee pain is a positive test.

Lateral Knee Pain

Check for anatomic deformity.
Palpate for tenderness. Palpate the site of tenderness with the knee straight and then flexed to 90°. Tenderness over the fibular head suggests fibular fracture. Tenderness between the femur and fibular head suggests lateral collateral ligament sprain. Tenderness just anterior to the femoral condyles suggests lateral meniscus tear. Tenderness over the lateral tibial condyle radiating over the lateral thigh suggests iliotibial band syndrome.
Check for joint laxity. Check for joint laxity by holding the knee and moving the foot medially. The amount of pain and the degree of laxity define the extent of lateral collateral ligament tear. Pain in the medial knee suggests medial meniscus tear.
Check for Ober's sign. With the patient supine, passively flex and abduct the leg, and then gently let go and have the patient maintain the leg position. Pain in the anterior thigh (positive Ober's sign) suggests tensor fascia lata syndrome. Pain in the lateral knee suggests iliotibial band syndrome.
Look for a meniscus tear. See "Check for Meniscus Tear" under "Medial Knee Pain," above.

A Knee That Gives Way

Check the basic landmarks for anatomic deformity.
Examine the anterior cruciate ligament. Perform the drawer test by pulling out on the tibia to see how far the tibia slides anteriorly over the femur. Sensing a sharp stopping point of movement is normal. Noting greater than 2 mm of movement and/or a boggy stopping point suggests a tear. Rotational movement (where only 1 condyle moves) suggests tear of the corresponding collateral ligament.
Now check the drawer test with the patient prone. Lachman sign is basically a drawer sign with the posterior knee supported to relax the hamstrings.
Check the Galway-MacIntosh test. With the patient supine, passively flex the hip with the knee extended. Anterior movement of the tibia more than 2 mm suggests a tear. Confirm by applying valgus force to the leg while passively flexing the knee. A sharp reduction of the subluxation at 20°-40° flexion is a positive test.
Check the posterior cruciate ligament. Perform the drawer test to see how far the tibia slides posteriorly over the femur. A sharp stopping point of movement is normal. Greater than 2 mm of movement and/or a boggy stopping point suggests a tear. Rotational movement, where only 1 condyle moves, suggests a tear of the corresponding collateral ligament.
Check for posterior sag by supporting the distal femur with pillows and see whether the tibia is posteriorly displaced. With the patient supine and knee flexed at 90°, push posteriorly on the tibial plateau. Posterior movement suggests a tear.
Check for Godfrey's sign. With the patient supine, passively flex at the hip with the knee in full extension. Pull up on the distal foot to 90° with varus and external rotation. Posterior movement of the tibia suggests a tear.
Check the collateral ligaments. Check for joint laxity with lateral movement. The degree of laxity defines the extent of medial collateral ligament tear. Hold the knee and move the foot medially. The amount of pain and the degree of laxity define the extent of lateral collateral ligament tear.
Check for meniscal tear. See "Check for Meniscus Tear" under "Medial Knee Pain," above
Palpate the lateral knee. Tenderness suggests proximal fibular fracture.

Additional Knee Assessment Pearls

  • A decrease in knee pain by forward flexion and lateral rotation of the foot suggests medial meniscus injury (Bragard's sign).
  • Increased anterior-posterior movement of the tibia over the femur with a click or pain suggests damage to the anterior or posterior cruciate ligaments (drawer or Rocher's sign).
  • With the patient sitting cross-legged, exert downward pressure along the medial aspect of the knee. Medial knee pain indicates a posterior horn lesion of the medial meniscus.
  • Anesthesia in the popliteal fossa suggests neurosyphilis (Bekhterev's sign).

General Evaluation of Lower Extremity Circulation

Inspect the legs from the groin to the feet noting any asymmetry, skin changes, hair distribution, varicosities, or edema. Signs of vascular insufficiency include pallor, coolness, cyanosis, atrophy, loss of hair, pigmentation along the shin or ankles, or ulcers. Check the capillary refill by pinching the great toes and noting the time that it takes for the color of the nail beds to return to normal (should be less than 3 seconds).

Arteries in the Legs

Assessing the femoral artery. Palpate the right femoral artery pulse by placing the index and middle fingers of your left hand over the patient's right inguinal ligament about midway between the right anterior superior iliac spine and the right symphysis pubis. Feel the opposite side with your right hand at the left inguinal ligament appreciating both pulses. Inequality of the pulse suggests vascular disease.
Now check the radial and femoral pulses on the right side. The femoral pulse should be felt before the radial pulse; if it is not, suspect aortoiliac disease. Listen for a vascular bruit. If one is present, observe whether it increases when the patient flexes and extends the ankle rapidly. Then, compress the femoral artery high in the femoral triangle near the inguinal ligament in the anterior and medial thigh. If the bruit increases, consider occlusion of the profunda artery. If the bruit decreases, consider occlusion of the common femoral artery or the proximal femoral artery. If the patient has a femoral popliteal bypass graft, hearing the bruit decrease with compression suggests that occlusion of the graft is eminent.
Popliteal artery. With the patient supine, place both hands around the knee and feel in the popliteal space. Slowly lift the knee until it is about 90°. If you cannot detect a pulse, then stop at that point. Feel the skin temperature over the shin. Normally, you would detect a point of warmth at the upper portion of the anterior thigh. Coolness in this area suggests acute vascular insufficiency. Note, however, that in chronic popliteal disease, vascular collaterals may cause the involved knee to feel warmer rather than cooler.
Dorsalis pedis and posterior tibial arteries. The dorsalis pedis pulse is usually felt along the dorsum of the foot just lateral to the extensor tendon of the great toe. The posterior tibial pulse is usually just behind and slightly below the medial malleolus.

Deep Venous Obstruction

With the patient supine, check the veins over the tibial plateau. Dilated veins that do not collapse with leg elevation suggest deep venous obstruction (Pratt's sign). If the skin on 1 leg is warm and stiff to a pinch (secondary to edema), then deep venous thrombosis is also indicated (Rose's sign). Measure the difference in circumference between the normal and distended leg -- both thighs and calves. Greater than 2.5 cm difference between the calves and greater than 2 cm between the thighs suggest deep venous thrombosis. Deep venous thrombosis is also suggested by the following:
  • Tenderness to percussion of the medial surface of the tibia (Lisker's sign);
  • Cough-induced pain that disappears when the proximal vein is compressed (Louvel's sign); and
  • Asymmetric tenderness to blood pressure cuff inflation at less than half the pressure of the opposite side (Löwenberg's sign).

Varicose Veins

Varicose veins with pulsations suggest tricuspid insufficiency. Hearing a murmur over the veins suggests tricuspid insufficiency. Dark purple discoloration of the skin with varicose veins suggests arteriovenous fistula.
Inspect the saphenous system for varicosities that will appear as large wormlike, tortuous vessels. Perform the manual compression test by having the patient stand and placing your right hand over the distal lower part of the varicose vein and your left hand over the proximal vein. Your hands will be about 15-20 cm apart. Compress the proximal portion of the varicose vein. If you feel a palpable pulsation in your distal hand, the test is positive.
Now perform Trendelenburg's test. Have the supine patient elevate the leg to 90° until the venous blood has drained from the great saphenous vein. Now place a tourniquet around the upper thigh of the patient's leg tightly enough to occlude the great saphenous vein but not the arterial pressure. Help the patient stand and look for venous filling. Slow filling (over 30 seconds) below the superficial veins while the tourniquet is applied is normal. Rapid filling of the superficial veins while the tourniquet is applied is abnormal, as is sudden additional filling of the superficial veins after the tourniquet has been released.

Additional Lower Extremity Circulation Pearls

  • Aneurysms of the abdominal aorta are associated with distal peripheral aneurysm.
  • Atherosclerosis, although a generalized metabolic disorder, tends to build up at bifurcations of major vessels. In the lower extremity, the superficial femoral artery becomes occluded at the adductor hiatus.
  • Patients with diabetes tend to have femoral-tibial occlusions, whereas nondiabetic patients tend to have ileal-femoral occlusions.

Assessment of Other Lower Extremity Conditions in the Geriatric Patient

Leg Fracture

Palpate over the greater trochanter. Pain suggests fracture if other signs are present. (Otherwise consider trochanteric bursitis or possible referred pain from the knee.) Laxity on palpation of the fascia lata, which connects the greater trochanter to the iliac crest, suggests femoral neck fracture (Allis' sign). Swelling along the inguinal ligament in a femoral neck fracture is called Laugier's sign. A transverse crease superior to the patella suggests a femoral fracture (Cleemann's sign). Ecchymosis and swelling along the inguinal ligament and inability to raise the thigh when the patient is sitting suggest fracture of the greater trochanter (Ludloff's sign). Limitation in the normal range of motion in the circular arc of the hip suggests proximal femoral fracture (Desault's sign). Relaxation of the extensor muscles of the thigh with intrascapular femoral fracture is called Langoria's sign. Increased diameter of the leg at the level of the malleoli suggests fibular fracture (Keen's sign of Pott's fracture).

Ankle Injury

Check landmarks for anatomic abnormality.
Ecchymoses and/or swelling. Ecchymosis under both malleoli with a broad-appearing heel suggests a calcaneal fracture. Ecchymosis and focal swelling over the fifth metatarsal suggest fracture of the proximal fifth metatarsal bone (Jones fracture). Swelling and tenderness over the lateral malleolus suggest a lateral sprain if anterior and inferior and a peroneal retinaculum sprain if on the posterior rim. Swelling and tenderness over the medial malleolus suggest a medial sprain, syndesmotic sprain, or tibialis tendonitis if posterior to the medial malleolus.
The talar tilt test. The talar tilt test is used to examine the integrity of the calcaneofibular or the deltoid ligament. Passively invert the foot and compare it with the opposite side. A > 10° difference implies a second- or third-degree lateral ankle sprain. The talus will tilt if both the talofibular and calcaneofibular ligaments are ruptured, but not with only 1 ruptured ligament (talar tilt sign).
Check for anterior movement of the calcaneus over the distal tibia. A firm endpoint and 4 mm of movement or less suggest a first-degree lateral sprain. Sensing a boggy endpoint and > 4 mm movement suggest a second-degree lateral sprain. Greater than 4 mm of movement and no endpoint suggest a third-degree lateral sprain.
Squeeze the malleoli together. Increased pain produced by squeezing the malleoli together suggests a syndesmotic sprain.
Externally rotate foot at the ankle. Increased pain produced by externally rotating the foot at the ankle suggests syndesmotic sprain.

Sciatica

Acute radicular low back pain (sciatica) radiates or shoots down 1 leg. The discomfort is often characterized as sharp, tingling, shooting, or "electrical" and may be exacerbated by coughing, straining, sneezing, or Valsalva maneuvers. It may occur in several ways, depending on the nerve roots affected. The pattern of weakness (if present) in the lower extremity is an important clue to the site of the neurologic dysfunction. Significant unilateral thigh and leg weakness suggests involvement by multiple nerve roots or peripheral nerves, although most peripheral nerve processes are not usually associated with back pain.
To differentiate sciatica from a hamstring injury, have the patient flex the hip with the leg straight until it feels painful and then have the patient dorsiflex the foot. A hamstring pull will not be painful, whereas with sciatica the pain will increase (Bragard's leg sign).
Other signs of sciatica include the following:
  • Pain on the contralateral side when the nonpainful side is flexed at the thigh and the leg is held in extension (Fajersztajn's sign);
  • Loss of sensation on the lateral portion of the foot (Szabo's sign);
  • Pain on straight leg raise that is relieved with leg flexion (Lasegue's sign);
  • Pain on adduction of the thigh (Bonnet's sign);
  • Pain in the buttocks when the great toe is hyperextended (Turyn's sign); and
  • Pain in the lower back or down the leg when the patient is supine (Linder's sign).

Signs of Endocrine or Metabolic Disorders

Symptoms in the legs can often indicate endocrine or metabolic disorders. Check for the following:
  • Cramping of the calves can be an early sign of diabetes mellitus (Unschuld's sign).
  • Difficulty walking up stairs or rising from a chair secondary to proximal muscle weakness suggests hyperthyroidism (Plummer's sign).
  • Leg weakness, pain on gently squeezing the calves, decreased knee-jerk reflexes, and anesthesia over the anterior thigh suggest Beriberi (Vedder's sign).
  • Hypocalcemia can be suggested when thigh flexion produces knee spasm and calf spasm (Pool-Schlesinger sign). Eversion of the foot when tapping over the peroneal nerve also suggests hypocalcemia (peroneal sign). Note: This is the author's favorite method to determine hypocalcemia because it seems to be the first to appear and last to disappear.
  • Tenderness to percussion over the tibia suggests chlorosis (Golonbov's sign).
  • Exquisite pain of the great toe when touching the fifth toe joint suggests gout (Plotz's sign).
  • Loss of hair on the posterior surface of the legs suggests gout (Tommasi's sign).
