Physical violence toward women during the periconceptional and antenatal periods occurs in all sociodemographic groups. Women with unwanted or mistimed pregnancies are at an increased risk for violence by their partners compared with women with intended pregnancies.

Older women and women of higher socioeconomic status who reported physical violence were more likely to delay entry into prenatal care than younger or less affluent women.

Pregnancy complications are common and not adequately measured by hospitalizations alone. Both more research and improved surveillance are needed to understand the effect of pregnancy complications on women's health and the reasons for the increased risk among poor or black women.

Skin testing separately and with equal concentrations of the purified milk proteins, casein, alpha-lactalbumin, beta-lactoglobulin, and BSA was done in 85 milk allergic children. For control purposes, intradermal tests with the same antigens were done in 102 normal children and 31 children allergic to non-milk substances. Six per cent of the normal children had weakly positive reactions. However, positive skin tests occurred in 68% of the children allergic, but not to milk, and in 59% of the children allergic to milk. In the milk allergic children, the incidence of positive reactions to each milk protein was similar. The incidence of positive skin tests in milk allergic children was higher than previously apprised. Positive skin tests in the milk allergic child were obtained long after the dietary elimination of milk antigens and after the disappearance of circulating milk antibodies as detected by a variety of techniques. In contrast to the control groups, strongly positive skin tests occurred only in milk allergic patients. Although no correlation was found between the results of all skin tests and the results of oral challenges with the same milk protein, a close correlation was found between the results of strongly positive skin tests and the results of oral challenge with the same milk protein. It appears that weakly positive skin tests with purified milk proteins have a little diagnostic value, but strongly positive skin tests have diagnostic significance.

Weather-related incidents account for the majority of general aviation accidents. Fortunately, a body of on-going, human factors research exists aimed at understanding and addressing this problem. The purpose of this session is to highlight that research. Topics will include the adequacy of pilots’ aviation weather knowledge and skills, weather information presentation, and use of technology to assess pilot performance and to improve pilot training. The session is designed to lead a discussion about the complexity of aviation weather, the dangers of weather in GA flight and the research underway to minimize the hazards and improve air safety.
