S-adenosyl-methionine (SAM; SAMe; ademetionine; adomet), an endogenous compound synthesized from methionine and adenosine-triphosphate (ATP), has been marketed in stores and on the internet as a dietary supplement to promote "emotional well being."

An unpublished 2-year randomized study (ENHANCE) on the effect of adding ezetimibe 10 mg to simvastatin 80 mg in 720 patients with heterozygous familial hypercholesterolemia has been in the news recently. About 80% of these patients had previously been treated with statins. The primary endpoint was the change in the intima-media thickness (IMT) of the carotid artery (baseline 0.68 and 0.69 mm); the IMT increased by 0.0111 mm with ezetimibe plus simvastatin and 0.0058 mm with simvastatin 80 mg alone (p=0.29). The ezetimibe- simvastatin combination lowered LDL-C by 58% compared to 41% lowering...

In 2014, the US Advisory Committee on Immunization Practices (ACIP) recommended that all adults 65 years old and older being vaccinated against pneumococcus for the first time receive the pneumococcal conjugate vaccine (PCV13) followed 6 to 12 months later by the pneumococcal polysaccharide vaccine (PPSV23)(Med Lett Drugs Ther 2014; 56:102). In June 2015, the ACIP changed the recommended interval between the two vaccines to >1 year for immunocompetent adults ≥65 years old (MMWR Morbid Mortal Wkly Rep 2015; 674:944). Separating the vaccines by a year or more may improve the immune...

Many of the overdoses occurred in patients with a history of emotional instability or suicide attempts. Accumulation of metabolites of propoxyphene can lead to central nervous system, cardiac and respiratory depression; convulsions and cardiotoxicity have occurred.A...
