In 1986 the rate of infectious syphilis (primary and secondary) in Los Angeles County began to rise from previously stable levels of about 23.5 per 100,000 to peak at 55.6 per 100,000 in 1987. The incidence of congenital syphilis increased from 205 cases in 1987 to 575 cases in 1989. The county''s Sexually Transmitted Disease Program instituted a disease-specific plan to address the epidemic. Factors considered in designing the program included the high morbidity and mortality associated with congenital infection, the existence of latent infection, self-limiting symptoms, and the availability of an inexpensive screening test and curative treatment. Policy changes implemented comprised expanded screening, expanded surveillance, increased contact tracing, and the initiation of condom promotion programs. To evaluate the relative effectiveness of Los Angeles County''s syphilis control efforts, the epidemic curve for infectious syphilis was compared with trends in other urban areas. Although the rate of infectious syphilis climbed a year earlier in Los Angeles than in other cities, it returned to baseline levels when other cities'' rates remained at epidemic levels.  相似文献

Psychiatric illness and behavioural problems among physicians are reviewed in this paper. Some studies suggest that the medical profession has a high rate of alcoholism, drug abuse and marital discord. As well, physicians appear to commit suicide and to seek admission to psychiatric institutions more frequently than comparable populations. Considered as etiologic factors in psychiatric illness among physicians are the role strain inherent in the profession and the personality development of individual practitioners prior to their entering medical school. The review concludes with suggestions for an improved approach to treatment and prevention.  相似文献

Studies indicate an increased risk of adverse late pregnancy events, such as preterm labor and preterm delivery, for practicing physicians. These adverse pregnancy outcomes also occur among pregnant women who work long hours with high levels of psychological stress, a mechanism most likely related to catecholamine and posturally mediated alterations in uterine blood flow. Further evaluation and research into the epidemiology of physicians'' pregnancies are needed because of the increasing number of women physicians in their childbearing years.  相似文献
