Sarcoidosis - 2014 Lancet review

Sarcoidosis is a systemic disease of unknown cause that is characterised by the formation of immune granulomas in various organs, mainly the lungs and the lymphatic system.

Sarcoidosis might be the result of an exaggerated granulomatous reaction after exposure to unidentified antigens in individuals who are genetically susceptible.

Diagnosis is made by symptoms, PFTs, CXR, CT, endobronchial ultrasound and PET for assessment of inflammatory activity.

Recognition of unexplained persistent disabling symptoms, fatigue, small-fibre neurological impairment, cognitive failure, and changes to health state and quality of life, has improved.

Mortality in patients with sarcoidosis is higher than that of the general population, mainly due to pulmonary fibrosis.

Driving Under the Influence, of Marijuana - NYTimes http://buff.ly/NadpmF -- If you are pulled over on suspicion of drunken driving, the police officer is likely to ask you to complete three tasks: Follow a pen with your eyes while the officer moves it back and forth; get out of the car and walk nine steps, heel to toe, turn on one foot and go back; and stand on one leg for 30 seconds. Score well on all three of these Olympic events, and there’s a very good chance that you are not drunk. This so-called standard field sobriety test has been shown to catch 88 percent of drivers under the influence of alcohol. But it is nowhere near as good at spotting a stoned driver.

Fibromyalgia - An Emerging but Controversial Condition - 2014 JAMA Update

Fibromyalgia is not a rheumatological disease but a central pain syndrome. It is a complicated condition that tends to last a long time, although people do get better.

The syndrome termed fibromyalgia or fibrositis has attracted the interest of investigators for quite some time. Although some authors believe that fibromyalgia is not a discrete condition, rheumatologists now report that fibromyalgia is one of the most common diagnoses in ambulatory practice. Recent estimates of the prevalence of fibromyalgia in the United States have ranged from 3 to 6 million.

This JAMA video introduces a free review article on fibromyalgia from April 2014



What is fibromyalgia?

Fibromyalgia can be thought of as a centralized pain state. Centralized pain is a lifelong disorder beginning in adolescence or young adulthood manifested by pain experienced in different body regions at different times.

How common is fibromyalgia?

Fibromyalgia is present in as much as 2% to 8% of the population, is characterized by widespread pain, and is often accompanied by fatigue, memory problems, and sleep disturbances.

How to treat fibromyalgia?

Numerous treatments are available for managing fibromyalgia that are supported by high-quality evidence:

- nonpharmacological therapies (education, exercise, cognitive behavioral therapy)
- pharmacological therapies (tricyclics, serotonin norepinephrine reuptake inhibitors, and gabapentinoids)
