Lymphedema is a set of pathologic conditions that are characterized by the regional accumulation of excessive amounts of interstitial protein-rich fluid. These occur as a result of an imbalance between the demand for lymphatic flow and the capacity of the lymphatic circulation. Lymphedema can result from either primary or acquired (secondary) disorders. In this review, the pathophysiology, classification, natural history, differential diagnosis, and treatment of lymphedema are discussed.

Both the incidence and prevalence of osteoarthritis increase with advancing age. Management of osteoarthritis in older adults focuses on reducing pain and other symptoms, minimizing functional limitation and disability from the disease, and avoiding the side effects associated with pharmacologic therapy. ⋯ We conclude that acetaminophen, when given at full doses of 4,000 mg/day, is more efficacious than placebo and has comparable efficacy to ibuprofen in the management of patients with osteoarthritis of the knee who have mild to moderate pain. Thus, acetaminophen merits a trial as initial therapy based on its cost-effectiveness and safety profile relative to NSAIDs.

Although sauna bathing causes various acute, transient cardiovascular and hormonal changes, it is well tolerated by most healthy adults and children. Sauna bathing does not influence fertility and is safe during the uncomplicated pregnancies of healthy women. Some studies have suggested that long-term sauna bathing may help lower blood pressure in patients with hypertension and improve the left ventricular ejection fraction in patients with chronic congestive heart failure, but additional data are needed to confirm these findings. ⋯ Contraindications to sauna bathing include unstable angina pectoris, recent myocardial infarction, and severe aortic stenosis. Sauna bathing is safe, however, for most people with coronary heart disease with stable angina pectoris or old myocardial infarction. Very few acute myocardial infarctions and sudden deaths occur in saunas, but alcohol consumption during sauna bathing increases the risk of hypotension, arrhythmia, and sudden death, and should be avoided.

Two recently reported studies of nonsteroidal anti-inflammatory drugs (NSAIDs), the Omeprazole versus Misoprostol for NSAID-induced Ulcer Management and the Acid Suppression Trial: Ranitidine versus Omeprazole for NSAID-associated Ulcer Treatment studies, concluded that omeprazole was superior to a subtherapeutic misoprostol or an ineffective dose of ranitidine for the endpoint, prevention of gastroduodenal ulcers in chronic NSAID users. Helicobacter pylori status was collected prospectively but was not reported. We report separate analyses for patients with unequivocal NSAID ulcers (H. pylori negative) and patients whose NSAID use was complicated by the presence of an active H. pylori infection. ⋯ That the Misoprostol Ulcer Complications Outcomes Safety Assessment (MUCOSA) trial found full-dose misoprostol to be more effective in ulcer prevention than it was in prevention of ulcer complications suggests that either many of the ulcer complications were related to H. pylori ulcers or that more antisecretory activity than can be provided with misoprostol is needed, or both. The question remains whether the combination of low-dose misoprostol plus an antisecretory drug (either an H(2)-receptor antagonist or a proton pump inhibitor) would provide superior results compared with either alone. That omeprazole was not superior to one half the dose of misoprostol used in the ulcer complication prevention, or MUCOSA, study indicates that it would not be prudent to suggest that ulcer prevention with omeprazole alone would be able to provide similar protection to misoprostol.
