Risk of heart attack and stroke goes up during holidays - Mayo Clinic video

From the Mayo Clinic YouTube channel: Are you at an increased risk of heart attack and stroke? Studies show the incidents rise during December and January, but particularly on Christmas Day and New Year's Day. Stay safe.

Jon Lord (70), a Hammond organ player, and a founding member of Deep Purple, who is currently recovering from cancer, says it very well: "Party hearty but look after yourselves. I wish you success and happiness, and above all I wish you health."

iPad app tests athletes for concussion - Cleveland Clinic video

An iPad app tests athletes for concussions (a Cleveland Clinic video). The players perform a series of balance, memory, vision, and reaction time experiments to obtain a baseline reading. If they receive a blow to the head during a game or practice, these tests can be redone to determine when it is safe for the athlete to return to action.

Mick Jagger (68) on staying fit: "Don’t look at the clouds of tomorrow through the sunshine of today"

Mick Jagger on staying fit: "You watch what you eat, you exercise, you have a bit of fun. You keep on going forward. Don’t stop. Do what makes you happy. Don’t look at the clouds of tomorrow through the sunshine of today. That’s it."

In other news, you can do anything with a blog (full website and all) - the launch site of Mick Jagger's supergroup SuperHeavy is basically a blog: http://www.superheavy.com

Their new hit "Miracle Worker" plays with medical terminology:

"You have a medical condition.

In an emergency I'm very well prepared
My scalpel, mask and gloves; don't ever get too scared.

No need for anesthetics, I'll go check your charts

You're a Miracle Worker.
You're a surgeon of love."

-- Lyrics from SuperHeavy - Miracle Worker.

Paget's disease - NHS Choices video

From the NHS Choices YouTube channel: An expert describes the various areas of the body that can be affected by Paget's disease - a condition in which the normal cycle of bone growth is disrupted.

The earliest references to journal clubs are in the memoirs and letters of Sir James Paget, a British surgeon, who described a group at St. Bartholomew’s Hospital in London in the mid-1800s as “a kind of club … a small room over a baker’s shop near the Hospital-gate where we could sit and read the journals.”

Sir Paget (11 January 1814 – 30 December 1899) is best remembered for Paget's disease and is considered, together with Rudolf Virchow, as one of the founders of scientific medical pathology.

A thin and visibly weak George Michael (48) told reporters outside his home in London that he wasn't supposed to speak for very long and was still recovering from a tracheotomy: "I got streptococca-something... It's a form of pneumonia and they spent three weeks keeping me alive basically," Michael said of the doctors in the Austrian hospital where the singer has been receiving treatment since he fell ill in November.

He added that he also wanted to hold a special show for the Austrian doctors who treated him. "I've spent the last 10 days since I woke up literally thanking people for saving my life."

How to Stay Active With Osteoarthritis: "Motion is Lotion"

Dr. Daniel Montero, a sports-medicine physician within the Department of Orthopedics at Mayo Clinic in Florida discusses what kind of exercises are you should take part in if you suffer from joint pain. Remember, "motion is lotion", says Dr. Montero.

Exercises you may need to avoid if you have moderate or severe osteoarthritis of the knee or hip include:

- Running and jogging. The difference between how much force goes through your joints jogging or running, as opposed to with walking, is sometimes more than 10-fold your whole body weight

- Jumping rope

- High-impact aerobics

- Any activity where, at any time, you have both feet off the ground at once, however briefly (basketball, jumping)

Fortunately, that leaves a lot of activities that are OK for people with knee and hip osteoarthritis and that can help keep you mobile - see the list at WebMD.

40% of police officers have a sleep disorder according to a JAMA study

More than a third of police officers have a sleep disorder, and those who do are more likely to experience heart disease, problems with job performance and rage toward suspects and citizens, says the NYTimes, citing a study in the JAMA. That figure is at least double the estimated 15-20% rate of sleep disorders seen in the general population.

Having a sleep disorder raised the odds of heart disease by 45%, and the odds of depression by 120%. It also raised the odds of being injured on the job by 22% and falling asleep while driving by 51%.


The JAMA report video.

The officers who had sleep disorders reported more instances of “uncontrolled anger” toward suspects and citizens and serious administrative errors. Sleep deprivation may affect the amygdala, a part of the brain where emotion is governed.

Of the 5,000 study participants, 40% screened positive for at least 1 sleep disorder, most of whom had not been diagnosed previously:

- 34% screened positive for obstructive sleep apnea
- 6.5% for moderate to severe insomnia
- 5.4% for shift work disorder

Not surprisingly, the police officer who had smaller body mass indexes were far less likely to have sleep apnea. System-wide practices can have a significant impact. For example, state police officers in Massachusetts are given one hour of paid exercise time four days a week to help them stay fit. They were less liekly to have sleep apnea.

How to manage your online reputation as a physician in 5 steps

1. Google yourself - repeat on a regular basis, at least once a month, and set up Google alerts to catch new mentions.

2. Correct mistakes and false information about you that is published online. Contact the site authors.

3. Create your own content - start a blog, Twitter account and Facebook page, use Google+ for draft posts. Send selected news to Twitter, try Facebook for updates from you practice. Link you own blog posts from Twitrter and Facebook.

Setup professional profiles on Google+ and LinkedIn.

Push irrelevant or non-reliable content down in the search results. The farther down the better, as 90% of people won't go past the first page of search results and 99% won't go past page 2.

4. Embrace constructive online criticism. Consider it a 360-degree evaluation.

5. Address actionable items such as "hot button issues" among patients - long waits, lack of response or slow responses.

Controversies in COPD treatment

Chronic obstructive pulmonary disease (COPD) is a chronic disorder with high mortality rates (one of the top 5 causes of death).

COPD is expected to rise to the third leading cause of death worldwide by 2030. More than 25% of COPD patients have never been smokers.

Some important controversies in COPD management still exist:

- The classic way to define COPD has been based on spirometric criteria, but more relevant diagnostic methods are needed that can be used to describe COPD severity and comorbidity

- Initiation of interventions earlier in the natural history of the disease to slow disease progression is debatable

- There are controversies about the role of inhaled corticosteroids (ICS) in the management of COPD

- Long-term antibiotics for prevention of exacerbation have had a resurgence in interest

New drugs are urgently needed for management of COPD exacerbation.

COPD is a complex disease and consists of several phenotypes that in future would guide its management.

Stress fractures

From a 2011 review in the journal American Family Physician:

Stress fractures are common injuries in athletes and military recruits. These typically affect lower extremities.

Symptoms of stress fractures

Stress fractures should be considered in patients who present with tenderness and/or edema after a recent increase in activity or repeated activity with limited rest.

The Barefoot Professor says barefoot running could minimize injuries although this approach is still experimental:



The differential diagnosis of stress fractures includes:

- tendinopathy
- compartment syndrome
- nerve or artery entrapment syndrome
- medial tibial stress syndrome (shin splints) can be distinguished from tibial stress fractures by diffuse tenderness along the length of the posteromedial tibial shaft and a lack of edema

Diagnosis of stress fractures

When stress fracture is suspected, plain radiography should be obtained initially and, if negative, may be repeated after 2-3 weeks for greater accuracy.

If an urgent diagnosis is needed, triple-phase bone scintigraphy (bone scan) or magnetic resonance imaging (MRI) should be considered. Both modalities have a similar sensitivity, but MRI has greater specificity.

Treatment of stress fractures

Treatment of stress fractures consists of:

- activity modification - nonweight-bearing crutches if needed for pain relief
- analgesics
- pneumatic bracing

After the pain is resolved, patients may gradually increase their level of activity.

Surgical consultation may be appropriate for patients with:

- stress fractures in high-risk locations
- nonunion
- recurrent stress fractures

Factors that Promote Positive Adaptation to Stress and Adversity

The phenomenon of resilience reflects positive adaptation despite contexts of risk, adversity, or trauma.

Factors that promote positive adaptation to stress and adversity include the following:

- self-esteem
- optimism
- internal control
- coping aimed at acceptance
- coping aimed at seeking emotional support
- social contacts



Tips for managing stress (2-minute BBC video):

- Take a few deep breaths
- Get plenty of exercise
- Socialize - don't stress alone, talk to someone and have a laugh
- Get out - go to the park

Acute pyelonephritis in women (2011 review)

This is a 2011 review from the official journal of the AAFP, American Family Physician:

Acute pyelonephritis is a bacterial infection of the renal pelvis and kidney most often seen in young women.

Symptoms of acute pyelonephritis

Most patients have fever, although it may be absent early in the illness. Flank pain is nearly universal.

Tests for acute pyelonephritis

A positive urinalysis confirms the diagnosis.

Urine culture should be obtained in all patients to guide antibiotic therapy if the patient does not respond to initial empiric antibiotic regimens.

Escherichia coli is the most common pathogen in acute pyelonephritis. In the past decade, there has been an increasing rate of E. coli resistance to extended-spectrum beta-lactam antibiotics.

Imaging, usually with contrast-enhanced CT is not necessary unless there is:

- no improvement in the patient's symptoms
- symptom recurrence after initial improvement

Treatment of acute pyelonephritis

Outpatient treatment is appropriate for most patients.

Oral fluoroquinolone is the initial outpatient therapy if the rate of fluoroquinolone resistance in the community is less than 10%. If the resistance rate exceeds 10%, an initial IV dose of ceftriaxone or gentamicin should be given, followed by an oral fluoroquinolone regimen.

Oral beta-lactam antibiotics and trimethoprim/sulfamethoxazole (TMP-SMX (Bactrim) are inappropriate for therapy because of high resistance rates.

Nephrology Cases

UpToDate is the most read medical reference tool - how did Harrison's, Cecil's, etc. manage to lose that war?

This the summary of my Twitter discussion with an academic nephrologist (by the way, the founding editor of UpToDate is also a nephrologist):

@DrVes: UpToDate is likely the most read medical reference tool, at least in the U.S. - how did Harrison's, Cecil's, etc. manage to lose that war?

@kidney_boy (Joel Topf): Reasons for UpToDate winning: Harrison's had no search, and an editorial style that told you about disease but not how to treat it

@DrVes: Exactly. It's amazing that those publishing companies didn't realize that they shipped "malfunctioning" product for years, and never fixed it.

@kidney_boy (Joel Topf): Harrison's is the great preclinical prof teaching pathophysiology, UpToDate is the smart clinician teaching you how to care for the patient with EBM.

@DrVes: UpToDate now has sections on pathophysiology, some of them quite good, check T-cells types, for example. Unfortunately, a lot of medical students get their basic pathology knowledge from Wikipedia nowadays. Just go to the library section where medical students are and have a look at the monitor screens during study time.

@kidney_boy (Joel Topf): Remember Harrison's is the youngest of the medical texts, it won by having regional approach (headache rather than CNS) to organization.

@DrVes: Classic-style textbooks (e.g. Harrisson's) feel like "half-book" nowadays. The doctors in training often find themselves asking "Where is the second part with treatment, updates, etc.?"

Are You Dependent on UpToDate for Your Clinical Practice?
"With UpToDate, students and interns may be as capable of teaching the resident (or attending) as visa versa"
Study: UpToDate More Likely than PubMed to Answer Patient Care Questions

Comments from Google Plus:

Neil Mehta - Ves one of the most useful aspects of Harrison's is/was the approach to symptoms. This is the first 100 or so pages of Harrison's. Understanding this can be a huge help in becoming a good clinician. It is pretty dense reading but internal medicine residents can benefit from spending time on this. Agree UpToDate is a tremendous resource. One thing to remember about U2D is that sections can be written by one author and this does run a risk of bias creeping in (no different than textbooks) but readers should learn to look at other sources/primary literature when necessary.

Ves Dimov - Right. UpToDate is far from perfect but it is very time efficient. It provides quick actionable info within 5-10 minutes of conducting a search. The depth of the content is limited by the person who wrote that particular article, of course.

Robert Silge - Yes, but by and large the people writing that content are qualified to do so. It is to medical textbooks what Wikipedia is to general reference books. Updates faster, to the point, and has info on (almost) everything. Its depth may be lacking, but for clinical practice I doubt the benefits of reading through primary literature is worth the time spent doing it for most endeavors.

And frankly for your first foray into a field, as a med student for example, Wikipedia is a darned useful place to start.

Ves Dimov - And that's why UpToDate is most users' favorite resource. One of the few drawbacks is the price though, $495 per year.

Robert Silge - Wonder how many people pay for it out of pocket vs use an institutional login?

Gary Levin - Up to date is like rounding with your attending or professor with instantaneous gratification. Harrison belongs in the library or for a second year med student to learn the language.

Headache subtypes: 30-year prospective cohort study

This BMJ study included 590 people aged 19-20 from a cohort of 4,500 residents of Zurich, Switzerland, interviewed 7 times across 30 years of follow-up.

The one-year prevalence of subtypes of headache were:

- 1% (female:male ratio of 2.8) for migraine with aura
- 11% (female:male ratio of 2.2) for migraine without aura
- 11% (female:male ratio of 1.2) for tension-type headache

The cumulative 30-year prevalence of headache subtypes were:

- 3% for migraine with aura
- 36% for migraine without aura
- 29% for tension-type headache

Despite the high prevalence of migraine without aura, most cases were transient and only 20% continued to have migraine for more than half of the follow-up period.

There was a substantial crossover among the subtypes and no specific pattern of progression.

The longitudinal overlap among subtypes of headache shows the developmental heterogeneity of headache syndromes.
