ReviewDrug injecting and HIV infection among the population of drug abusers in Asia.
Opium has been produced and consumed since the nineteenth century in the areas of Asia currently referred to as the Golden Crescent and the Golden Triangle. In the 1970s and 1980s, most countries from Afghanistan to Japan experienced a heroin epidemic of varying degrees of severity. Opium and heroin abuse appeared to be more severe in countries and areas where those drugs were produced, an exception being Hong Kong, which has had a large population of heroin abusers for more than two decades. ⋯ Great caution should be exercised in interpreting prevalence because of vast differences in methods of assessment. Given the vulnerability of intravenous drug abusers to rapid transmission of HIV infection, the prevention of drug injecting is of paramount importance in arresting the spread of the epidemic. Efforts to contain drug abuse, though difficult, are a principal means of achieving that end.

A system has been established to document births and deaths in children in a large, rural, West African population, using community reporters. Causes of death in children under the age of 5 years were investigated using post-mortem questionnaires completed by field assistants. There was a marked seasonal incidence of all major causes of death with peak rates in the rainy season. ⋯ Other major causes of death were malaria, acute gastro-enteritis and chronic diarrhoea with malnutrition. Mortality from all the major causes of death decreased with increasing village size. Our findings have implications for interventions against childhood mortality.

Assessment of respiratory rate and chest indrawing in children with ARI by primary care physicians in Egypt.
In a baseline study for training purposes, two indicators of acute respiratory infections (the respiratory rate (RR) and chest indrawing) were assessed by Ministry of Health physicians in Egypt using a WHO test videotape. Chest indrawing, as defined by the WHO Acute Respiratory Infections (ARI) programme, was not widely recognized by current health personnel. Viewing a WHO training videotape led to significantly more correct assessments of chest indrawing compared with a group that had not viewed this videotape. ⋯ Rates counted over 60 seconds were more accurate than 30-second counts although the difference between them was not clinically significant. Counting of rates using timers with audible cues was comparable to using watches with second hands. Careful training of primary health workers in the assessment of RR and chest indrawing is essential if these clinical findings are to be used as reliable indicators in pneumonia treatment algorithms.

Female sexual partners of injection drug users are at risk for AIDS because of their association with street drug cultures and all their concomitant risks, including their own non-injecting drug use. This study examines a model of the social determinants of HIV-associated sexual risk behaviors. ⋯ The findings show that crack cocaine use is the strongest contributor to the model, which explains fourteen percent of the variance of sexual risk behavior. The findings suggest that the risks associated with sexual practices are much greater for crack cocaine users than among non users of crack.

The heterosexual spread of HIV-1 is occurring at different rates in different parts of the world. The transmission probability of HIV-1 per sexual contact is low, but may be greatly enhanced by several cofactors. Sexually transmitted diseases (STD), especially genital ulcers, may be such factors. So far, epidemiological evidence that other STD facilitate HIV-1 transmission is weak. The objective of this study was to determine whether treatable STD enhanced sexual transmission of HIV-1 in a cohort of female prostitutes in Kinshasa, Zaire. ⋯ Non-ulcerative STD were risk factors for sexual transmission of HIV-1 in women, after controlling for sexual exposure. Because of their high prevalence in some populations, non-ulcerative STD may represent a considerable population-attributable risk in the transmission of HIV-1 worldwide. The identification of treatable STD as risk factors for HIV-1 transmission offers an important additional strategy for the prevention of HIV/AIDS.
