Prior to 1989, Krabi and Satun, two neighbouring provinces with similar socioeconomic background and health service coverage, had the highest reported incidence rates of neonatal tetanus in Thailand (3 per 1000 livebirths). A control programme was conducted between 1989 and 1991. The objective of this study was to examine changes in prevalence of risk factors among the population and changes in incidence rates of this disease due to this programme. ⋯ From 1989 to 1991, in Krabi Province, the coverage of at least two doses of tetanus toxoid injections at any time prior to delivery, delivery by trained health personnel, acceptable sterile technique for umbilical cord cutting and correct method of dressing the umbilical stump rose from 70 to 88%, 55-80% cent, 80-94% and 40-74%, respectively. Reduction in the incidence rate of neonatal tetanus was achieved by strengthening of routine health services with or without additional mass immunization. Considering that the coverage of immunization has not yet been completed and the prevalence rates of different risk factors are still high, further attempts to improve the problem of neonatal tetanus are necessary.

The epidemiologic features of HBV, HDV and HIV in the general population of Hamadan province of Iran were studied. A total of 4930 subjects (1649 males and 3281 females) constituted the study population. Seropositivity for any HBV marker was found in 25.72% of the subjects. ⋯ Our results suggest that horizontal transmission is likely to be the primary mode of acquisition of HBV infection in children and young adults. Also infection is partly transmitted before or soon after birth to babies of HBsAg-carrier mothers. Socioeconomic and demographic variables have a greater impact on the prevalence of HBV infection than blood or medical care variables in our population.

Until recently tuberculosis was considered a well controlled disease, at least in developed countries. In developing countries, more than seven million people are affected by active tuberculosis. ⋯ The three major strategies for controlling tuberculosis remain BCG vaccination in children, appropriate preventive therapy and, most importantly, reducing the sources of infection through case finding and curative treatment. Research and resources to improve on these strategies should be given high priority by the international health community.

Three patients who showed an allergic reaction to latex products are described. By means of history, skin tests, measurement of IgE antibodies against latex and challenge tests the diagnosis could be established. ⋯ Latex allergy should be considered when evaluating 'idiopathic' anaphylaxis during an operation. Moreover, latex allergy may be the cause of occupational rhinitis and asthma.
