Are compression stockings safe and effective for the prevention of deep venous thrombosis (DVT) in airline passengers?

According to a Cochrane review of nine randomized controlled trials, compression stockings are effective at reducing asymptomatic DVT in airline passengers taking flights longer than five hours.

In which patients should a diagnosis of mature-onset diabetes of the young (MODY) be considered?

MODY should be considered in nonobese patients who have diabetes mellitus that was diagnosed at a young age (younger than 30 years), preserved pancreatic beta-cell function, lack of pancreatic beta-cell autoimmunity, and a strong family history of diabetes.

What is the preferred pharmacologic treatment for MODY?

Sulfonylureas are the preferred pharmacologic therapy for hyperglycemia in MODY1 and MODY3. Pharmacologic treatment of hyperglycemia is not required for MODY2 because the risk of vascular complications is low, and patients are asymptomatic.

Should fever of unknown origin be treated with empiric antibiotics?
