Comparative StudyDiagnosing anaemia in pregnancy in rural clinics: assessing the potential of the Haemoglobin Colour Scale.
Anaemia in pregnancy is a common and severe problem in many developing countries. Because of lack of resources and staff motivation, screening for anaemia is often solely by clinical examination of the conjunctiva or is not carried out at all. A new colour scale for the estimation of haemoglobin concentration has been developed by WHO. ⋯ Sensitivity using the colour scale was consistently better than for conjunctival inspection alone and interobserver agreement and agreement with Coulter Counter measurements was good. The Haemoglobin Colour Scale is simple to use, well accepted, cheap and gives immediate results. It shows considerable potential for use in screening for anaemia in antenatal clinics in settings where resources are limited.

To assess the magnitude, causes and associated factors of maternal mortality in Surinam. ⋯ Maternal mortality was found to be several times higher than had been officially reported for Surinam during the previous three decades. Improvement of maternity care services in Surinam is needed, and has to be addressed at all levels, from the community, health centre and hospital to the highest level of organisation.

Transmission of hepatitis B, hepatitis C and human immunodeficiency viruses through unsafe injections in the developing world: model-based regional estimates.
Thousands of millions of injections are delivered every year in developing countries, many of them unsafe, and the transmission of certain bloodborne pathogens via this route is thought to be a major public health problem. In this article we report global and regional estimates of the number of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections that may occur from unsafe injections in the developing world. The estimates were determined using quantitative data on unsafe injection practices, transmission efficiency and disease burden of HBV, HCV and HIV and the prevalence of injection use obtained from a review of the literature. ⋯ The estimated range for HBV infections is in accordance with several epidemiological studies that attributed at least 20% of all new HBV infections to unsafe injections in developing countries. Our results suggest that unsafe injections may lead to a high number of infections with bloodborne pathogens. A major initiative is therefore needed to improve injection safety and decrease injection overuse in many countries.

Mass vaccination with a two-dose oral cholera vaccine in a refugee camp.
In refugee settings, the use of cholera vaccines is controversial since a mass vaccination campaign might disrupt other priority interventions. We therefore conducted a study to assess the feasibility of such a campaign using a two-dose oral cholera vaccine in a refugee camp. The campaign, using killed whole-cell/recombinant B-subunit cholera vaccine, was carried out in October 1997 among 44,000 south Sudanese refugees in Uganda. ⋯ Mass vaccination of a large refugee population with an oral cholera vaccine therefore proved to be feasible. A pre-emptive vaccination strategy could be considered in stable refugee settings and in urban slums in high-risk areas. However, the potential cost of the vaccine and the absence of quickly accessible stockpiles are major drawbacks for its large-scale use.

Ethnic monitoring of all new and first attenders in the year to community family planning clinics was carried out by means of an anonymous questionnaire during April to June 1997 inclusive to ascertain whether ethnic minority women attend family planning clinics. A 73 per cent response rate (2664 questionnaires) was obtained. The results showed that women came from a wide variety of ethnic groups and from almost every country in the world. ⋯ However at all but one of the clinic sites, which are spread around the borough, the UK European group was in a minority ranging from 20 to 47 per cent in attendance, compared to other ethnic groups. It is proposed that ethnic monitoring will be routinely recorded from April 1998 for new and first time attenders. It is also planned to work more closely with various ethnic minority groups in the community.
