ReviewNecrotizing soft tissue infections: a primary care review.
Patients with necrotizing soft tissue infections often present initially to family physicians. These infections must be detected and treated rapidly to prevent loss of limb or a fatal outcome. Unfortunately, necrotizing soft tissue infections have no pathognomonic signs. ⋯ Generally, bacterial and toxin-related effects converge to cause skin necrosis, shock, and multisystem organ failure. Aggressive debridement of infected tissues is critical to management. Antimicrobial therapy is important but remains secondary to the removal of diseased and necrotic tissues.

Carpal tunnel syndrome affects approximately 3 percent of adults in the United States. Pain and paresthesias in the distribution of the median nerve are the classic symptoms. While Tinel's sign and a positive Phalen's maneuver are classic clinical signs of the syndrome, hypalgesia and weak thumb abduction are more predictive of abnormal nerve conduction studies. ⋯ A recent systematic review demonstrated that nonsteroidal anti-inflammatory drugs, pyridoxine, and diuretics are no more effective than placebo in relieving the symptoms of carpal tunnel syndrome. If symptoms are refractory to conservative measures or if nerve conduction studies show severe entrapment, open or endoscopic carpal tunnel release may be necessary. Carpal tunnel syndrome should be treated conservatively in pregnant women because spontaneous postpartum resolution is common.

Nausea and vomiting of pregnancy, commonly known as "morning sickness," affects approximately 80 percent of pregnant women. Although several theories have been proposed, the exact cause remains unclear. Recent research has implicated Helicobacter pylori as one possible cause. ⋯ Women with more complicated nausea and vomiting of pregnancy also may need pharmacologic therapy. Several medications, including pyridoxine and doxylamine, have been shown to be safe and effective treatments. Pregnant women who have severe vomiting may require hospitalization, orally or intravenously administered corticosteroid therapy, and total parenteral nutrition.
