Silent embolism of a large thrombus in transit through the patent foramen ovale: a case report.

Background: Detection of a thrombus in transit through a patent foramen ovale (PFO) is extremely rare due to the transient nature of the process. We report an unusual case of a large, paradoxical embolus in transit seen on echocardiography through a PFO that was not found upon atriotomy.

Case Summary: An 80-year-old woman presented to the emergency room with shortness of breath and right leg pain.

Phase I, single-dose, dose-escalating study of inhaled dry powder capreomycin: a new approach to therapy of drug-resistant tuberculosis.

Multidrug-resistant tuberculosis (MDR-TB) threatens global TB control. The lengthy treatment includes one of the injectable drugs kanamycin, amikacin, and capreomycin, usually for the first 6 months. These drugs have potentially serious toxicities, and when given as intramuscular injections, dosing can be painful.

Pharmacokinetics of sequential doses of capreomycin powder for inhalation in guinea pigs.

The global control of tuberculosis (TB) is at risk by the spread of multidrug-resistant TB (MDR TB). Treatment of MDR TB is lengthy and involves injected drugs, such as capreomycin, that have severe side effects. It was previously reported that a single daily dose of inhaled capreomycin had a positive effect on the bacterial burden of TB-infected guinea pigs.

Elevated fructosamine levels in acquired immunodeficiency syndrome.

Objective: To investigate whether the mechanism of increased glycation in acquired immunodeficiency syndrome (AIDS) is due to an alteration in a circulatory plasma enhancer.

Methods: We assessed glycation of serum protein and hemoglobin in patients with AIDS without altered carbohydrate metabolism. Fasting concentrations of glucose, ethanol, vitamin E, fructosamine, hemoglobin, hemoglobin A1c (A1C), and partial pressure of alveolar oxygen (PAO2) were determined in 50 men with AIDS and in 25 age-matched healthy men in whom normal glucose tolerance was established by oral glucose tolerance tests.

Is beta-cell failure in type 2 diabetes mellitus reversible?

Background: In the UK Prospective Diabetes Study (UKPDS), many subjects maintained glycemic goal (HbA(1c) < 7.0%) at 9 years, showing that beta-cell function was preserved and that the initial decline in beta-cell function recovered with sulphonylureas. Moreover, obese subjects using high daily doses of insulin for several years rarely require insulin or oral hypoglycemic agents to maintain their glycemic goal following weight loss achieved by gastric bypass surgery.
