Declining mortality in international sterilization services.

Between 1973 and 1988, AVSC supported 1,516,478 female sterilizations and 401,856 vasectomies in 50 countries. Overall, 73 deaths were attributable to voluntary sterilization procedures (yielding mortality rates of 4.7 deaths per 100,000 female sterilizations and 0.5 per 100,000 vasectomies). Causes of death, in order of frequency, were anesthesia (22), intestinal injury (20), infection (19), intra-abdominal hemorrhage (6) and other (6). The female sterilization mortality rate declined from 7.1 per 100,000 procedures in 1973-1981 to 3.7 per 100,000 in 1982-1988. Safer anesthesia practices and improved infection control contributed most to this decline. The mortality rate related to surgical errors declined proportionately less than the rates related to anesthesia and infection. Contraceptive sterilization has become a very safe procedure in these 50 countries, where anesthesia (local and general), surgical technique (minilaparotomy and laparoscopy) and timing of the procedure (interval and postpartum) vary substantially. Future deaths will probably be rare. However, expert surgeons should review each case because identifying the most likely cause of death is always complex and these analyses help shape surgical contraception practices.

Ankylosing spondylitis in nonhuman primates: the drill and the siamang.

Nonhuman primates are known to be susceptible to many of the arthritides that afflict humans. Psoriatic like spondyloarthropathies have been reported in gorillas and skeletal hyperostosis in gibbons, rhesus monkeys, and gorillas, and additional cases of both of these conditions occurring in drills (baboons) are noted in this report. One western lowland gorilla and two rhesus monkeys with clinical features consistent with ankylosing spondylitis have been documented previously. Two additional nonhuman primate species with radiographic evidence of ankylosing spondylitis are described. A siamang (gibbon) and two drills (baboons) with the classic radiographic features of ankylosing spondylitis, namely a bamboo spine and sacroiliac joint fusion, are reported.

EPA in the prevention of restenosis post PTCA.

The effect of fish oil on restenosis was evaluated in patients undergoing coronary balloon angioplasty. In addition to routine pharmacotherapy, subjects were given 2.8 g of eicosapentanoic acid (EPA) daily. Treatment was started within twenty-four hours after successful percutaneous transluminal coronary angioplasty (PTCA). After six months of therapy, participants were subjected to coronary arteriography, exercise scintigraphy, exercise electrocardiography, or clinical evaluation. Follow-up evaluation involved 97 coronary lesions in 85 patients. Partial or significant restenosis occurred in 36.5% of patients and 33% of vessels. The presence of severe stenosis before PTCA, dissection, thrombus, multilesion PTCA, and template bleeding time values were not correlated with restenosis. Dilation of the left anterior descending (LAD) and a residual stenosis greater than or equal to 35% were associated with restenosis. Approximately 20% of the patients related difficulty in taking the fish oil. Furthermore, these results show no advantage over expected restenosis rates.

Complications of vasectomies in the United States.

Physicians in the United States were surveyed in 1983 to gather information concerning the number of vasectomies they performed in 1982 as well as their use of anesthesia and complications of those vasectomies. Most urologists performed vasectomies, whereas family physicians and general surgeons were less likely to do so. As expected, most physicians used local anesthesia, occasionally in combination with a sedative; however, 22 percent of physicians reported using general anesthesia for at least some vasectomies. Complication rates were in the ranges reported by previous case series. Physicians who performed between one and ten vasectomies in 1982 had higher rates of hematoma and hospitalization for treatment of a complication than physicians who performed more vasectomies. Maintenance of surgical skills appears to be important in preventing complications of this usually low-risk procedure.
