Comparative StudyRehabilitation of the expanded programme on immunization in Sudan following a poliomyelitis outbreak.
In 1993 a large outbreak of paralytic poliomyelitis occurred in Sudan as a result of an accumulation of large numbers of susceptible children that was accelerated by faltering immunization services. The extent of the outbreak led to the rapid rehabilitation of Sudan's Expanded Programme on Immunization (EPI); the government began financing vaccine purchase, operational aspects of EPI were decentralized, vaccine delivery was changed from a mobile to a fixed-site strategy, a solar cold chain network was installed, inservice training was resuscitated, and social mobilization was enhanced. National immunization days (NIDs) for poliomyelitis eradication were conducted throughout the country, including the southern states during a cease fire in areas of conflict. ⋯ Supplemental tetanus toxoid immunization of women of child-bearing age began in three provinces at high risk for neonatal tetanus. From 1994 to 1996 reported immunization coverage increased and the incidence of all EPI target diseases fell. Trends in coverage, disease incidence, financing, and the implementation of WHO-recommended disease-control strategies suggest that more sustainable immunization services have been re-established in Sudan.

Outbreak of viral hepatitis B in a rural community in India linked to inadequately sterilized needles and syringes.
In India, virtually all outbreaks of viral hepatitis are considered to be due to faeco-orally transmitted hepatitis E virus. Recently, a cluster of 15 cases of viral hepatitis B was found in three villages in Gujarat State. ⋯ But for the many fatalities within 2-3 weeks of the onset of illness, the outbreak would have gone unnoticed. The findings emphasize the importance of inadequately sterilized needles and syringes in the transmission of viral hepatitis B in India, the need to strengthen the routine surveillance system, and to organize an education campaign targeting all health care workers including private practitioners, especially those working in rural areas, as well as the public at large, to take all possible measures to prevent this often fatal infection.

Third degree atrioventricular block is considered present when none of the atrial impulses are conducted to the ventricles because of a disruption in the conducting system. Third degree atrioventricular block is usually considered a serious sign but most studies have been performed on hospitalized patients or certain professional groups. The objective of this study was to find the prevalence of third degree atrioventricular block in a representative population sample and estimate its prognostic significance. ⋯ The prevalence of third degree atrioventricular block in this general population was low but nevertheless considerably higher than previously reported. The block was temporary in the majority of subjects. All had some underlying heart disease which seemed to affect the prognosis more than the heart block. In this survey fewer subjects than expected were found to need a pacemaker.

While many studies investigated the higher morbidity and mortality levels of indigenous Australians in the high-density indigenous areas in the Northern Territory, Western Australia and South Australia, few examined the situation in New South Wales, where more than 28% of the indigenous population lives. Admissions to acute public and private hospitals in New South Wales for 1989-1995 are used in the study reported here to examine indigenous health and its differential patterns by disease categories. ⋯ Age-standardised estimates for the indigenous population are provided. Age composition of admissions for each disease category and admissions by residential area are also estimated.
