Deaths exhibit a seasonal pattern in most parts of the world. Analyses of deaths for the years 1972-1974 from the vital registration system of Matlab, Bangladesh, published in this journal 17 years ago, showed sinusoidal seasonal patterns. As death rates have declined in other nations, the seasonal pattern is attenuated. Death rates have declined substantially in Bangladesh in the past two decades. Thus, the present study examines monthly counts of deaths from Matlab data for a period 15 years later and tests the hypothesis of a decrease or shift in seasonality over time. ⋯ Marked seasonal patterns of deaths persist in the Matlab area of Bangladesh even as the level of mortality has declined.

The impact of consanguinity and inbreeding on perinatal mortality in Karachi, Pakistan.
Close consanguineous unions continue to be extremely common in much of West Asia, including Pakistan. However, the impact of inbreeding on offspring mortality, particularly perinatal mortality, remains poorly documented. This paper attempts to measure the mortality risks associated with consanguinity and inbreeding while controlling for the effects of other potential confounders. ⋯ When parental inbreeding was also taken into account, the adjusted odds ratio for perinatal mortality increased further. Analysis of a subsample of data limited to pregnancies to women aged 35 years or above (at the time of the survey) showed that, despite adjustment for important biological and socio-demographic factors, both consanguinity and inbreeding remained important predictors of perinatal mortality in the offspring. Implications of the present study for further research are highlighted.

Hospital use for potentially preventable conditions in aboriginal and Torres Strait Islander and other Australian populations.
The poor state of Aboriginal and Torres Strait Islander health has been documented in many ways, most obviously by comparing the relatively higher age-specific mortality and morbidity rates. This paper demonstrates the use of acute hospital separation data as a way to identify potential deficiencies in providing appropriate primary health care services for Aboriginal and Torres Strait Islander populations. It does so by using 'ambulatory sensitive conditions': those conditions (and procedures) for which high-quality appropriate primary health services deliverable under ideal circumstances are though to potentially reduce or eliminate the need for hospitalisation. ⋯ In this study, 1993-94 acute hospital separation data from NSW, Queensland, South Australia, Western Australia and the Northern Territory were used to calculate separation rates and odds ratios for Aboriginal and Torres Strait Islander and non-Aboriginal and Torres Strait Islander populations. Age-specific acute hospital separation rates for ambulatory sensitive conditions were 1.7 to 11 times higher for the Aboriginal and Torres Strait Islander populations studied. This supports clinical contentions that much Aboriginal and Torres Strait Islander morbidity and mortality is preventable and that further consideration is needed to service delivery reform at all levels in the health system and the distribution of funding.

Determinants of progression of HIV infection in a Greek hemophilia cohort followed for up to 16 years after seroconversion.
Our objectives are to describe the progression of HIV disease and to assess the influence of hemophilia-related variables, age at infection, and antibodies to cytomegalovirus infection (anti-CMV) in a Greek cohort of 158 HIV-1-positive hemophilic men, who received prospective follow-up for up to 16 years after infection. A total of 79 patients had died, representing a cumulative progression rate of 72.4% (95% confidence interval [CI], 56.6-83.3). A significant proportion of the mortality (30%) resulted from conditions not formally related to AIDS, with liver failure and cerebral hemorrhage predominant. ⋯ Appropriate modeling showed a nonlinear age effect, with a steeper increase of relative hazard for patients >40 years of age at seroconversion. The age effect remained significant even after controlling for current CD4 cell count. Further investigation is required to elucidate the mechanisms of the age effect and the contribution of HCV coinfection on the disease progression.

Little is known about birth or mortality rates of twins in The Gambia. There are no reports of the causes of death among twins in sub-Saharan Africa. We identified twin births and deaths from a community-based study which had been carried out in a large rural region of The Gambia over a 5-year period from 1989 to 1993. ⋯ In comparison, the early-neonatal, late-neonatal and post-neonatal mortality rates of singletons were 18.6, 16.0 and 41.1 per 1000, respectively. In the post-neonatal period, malnutrition was more frequently a cause of death among twins than among singletons (7.8 per 1000 twin births vs 2.0 per 1000 singleton births; p = 0.0008). Appropriate strategies for preventing malnutrition are required for this high-risk group.
