Survey of enteropathogenic agents in children with and without diarrhoea in Ghana.

A survey was carried out over 1 year in a rural area of Ghana on the isolation, detection and/or identification of enteric pathogens from children under 5 years of age with and without diarrhoea. The isolation and detection rate of Shigella flexneri, Shigella dysenteriae, Giardia lamblia and Rotavirus were higher in children with diarrhoea than in controls. Yersinia enterocolitica, Vibrio cholerae and Vibrio parahaemolyticus were not isolated during the period of this survey. The incidence of other enteropathogenic bacteria and parasites identified in the diarrhoeal and non-diarrhoeal children was calculated and is discussed in this study.

Parasitological and clinical aspects of bancroftian filariasis in Kassena-Nankana District, upper east region, Ghana.

A survey of the prevalence of bancroftian filariasis was conducted in August-September 1992 in the northern part of the Kassena-Nankana District, Upper East Region, Ghana. 200 compounds from 3 different communities were randomly selected from the vitamin A trial database. All resident compound members were examined for clinical manifestations of lymphatic filariasis and capillary blood was obtained between 21:00 and 01:00 and examined using the counting chamber technique. 1603 people were examined, 741 males and 862 females. The overall prevalence of microfilaraemia was 32.4% (95% confidence interval 30.1-34.7). Geometric mean microfilaria density (infected persons only) was 794 per mL. The most important clinical manifestation was hydrocele (in 32% of males) followed by limb elephantiasis (in 3.6% of the study population). There was no significant difference between the 3 communities in clinical or parasitological findings.

Patterns of malaria morbidity and mortality in children in northern Ghana.

A malaria prevalence survey was carried out in young children in northern Ghana between October 1990 and September 1991, in an area with continuous mortality and morbidity surveillance. There was marked seasonal variation in malaria deaths, reported fevers, parasite rates and mean parasite densities, with parasite rates reaching 85-94% in the wet season. The monthly numbers of malaria deaths were highly correlated with rainfall in the previous 2 months (r = 0.90, P < 0.001). Parasite rates were highest in the oldest children (5-7 years), but parasite densities and rates of febrile illness were highest in those 6-11 months old. Haemoglobin levels were also at their lowest in this age group. The predominant species, Plasmodium falciparum, was present in 71% of all blood films. Febrile illness was well recognized by mothers, but it was not possible to construct a simple clinical diagnostic algorithm which would identify even 50% of children with high levels of malaria parasitaemia (> or = 4000 parasites/microL). Malariometric indicators appear to have changed little in this area since a previous survey in 1955.

Lay reporting of elephantiasis of the leg in northern Ghana.

Within a large scale community trial in northern Ghana lay interviewers were trained to inquire about and identify elephantiasis of the leg by the use of local terms and simple examination of respondents. This was repeated a year later after moving the interviewers to different geographical areas. The proportions of extended family compounds reported to have at least one member with elephantiasis of the leg were 12.2% and 12.1 % respectively in the first and second surveys (kappa = 0.60). 'Blind' re-examination of a sub-sample by a physician showed a high level of agreement with the lay interviewer's findings in the first and second surveys (kappa = 0.67 and 0.82 respectively). This study has shown that lay people, even with minimal training, can obtain repeatable and valid estimates of the prevalence of elephantiasis of the leg, at least within an area where local terms for the condition are available. This method could potentially be used for other diseases with visible manifestations.

Mortality in a seven-and-a-half-year follow-up of a trial of insecticide-treated mosquito nets in Ghana.

A 17% efficacy in preventing all-cause mortality in children aged 6-59 months was previously reported from a cluster-randomized controlled trial of insecticide-treated mosquito nets (ITNs) carried out in the Kassena-Nankana District of northern Ghana from July 1993-June 1995. A follow-up until the end of 2000 found no indication in any age group of increased mortality in the ITN group after the end of the randomized intervention. These results should further encourage the use of ITNs as a malaria control tool in areas of high endemicity of Plasmodium falciparum.

Antimalarial prescribing practices: a challenge to malaria control in Ghana.

OBJECTIVE: The study was conducted to determine antimalarial prescribing practices among prescribers in 2 of the 6 sentinel sites established to document antimalarial drug efficacy in Ghana in order to provide some explanation underlying chloroquine treatment failures in the country. SUBJECTS AND METHODS: The study was descriptive combining both qualitative and quantitative designs. The qualitative design involved in-depth interviews of general prescribers in the Wassa West and Kassena Nankana districts using an interview guide. The quantitative design involved a review of Outpatient Department prescriptions of 100 patients clinically diagnosed as having malaria within the year 2000 in each of the 7 selected health care facilities. RESULTS: The overall number of drugs prescribed per patient encounter was 4.3 in the Wassa West district and 3.0 in the Kassena Nankana district. The number of drugs per patient encounter was 5.4 and 3.7 in private and government health care facilities, respectively. The commonly prescribed antimalarial drug in all the health care facilities visited was chloroquine. However, only 9.8% of prescriptions in private health care facilities contained correct doses of chloroquine compared to 54% in government health care facilities (p = 0.000). Prescriptions containing chloroquine injections were least likely to have correct doses of chloroquine. CONCLUSION: The findings indicate that although chloroquine remained the first-line drug in the treatment of uncomplicated malaria in the two districts, the level of appropriateness of doses prescribed was generally low. Inappropriate doses of chloroquine prescribed were more prevalent in private than government health care facilities, and among prescriptions containing injections.

The Navrongo Community Health and Family Planning Project.

In 1994, an experiment was launched by the Navrongo Health Research Centre that will test the demographic impact of community health and family planning services in a rural, traditional area of northern Ghana. While exhaustive social research has been directed to clarifying societal constraints to reproductive change, relatively little is known about how African cultural characteristics can be a resource to family planning programs. This study will clarify ways in which cultural resources of a traditional African society can be used in efforts to foster reproductive change. This article reviews characteristics of the study population, the design of the Navrongo experiment, and the research plan. The Navrongo Project will be the first African experimental trial of the demographic impact of family planning.

Developing a culturally appropriate family planning program for the Navrongo experiment.

This article describes the first six months of the strategic planning process to develop a culturally appropriate community health and family planning program for a traditional community in a district of northern Ghana, served by the Navrongo Health Research Centre. To explain the context within which fertility decisions are made, this article describes the district's severe ecological, social, economic, and health constraints to family planning. It discusses related programmatic obstacles and presents the strategies developed to respond to them. A system of care has been developed that is closely coordinated with traditional leaders and communication networks. Management systems support outreach workers by emphasizing the importance of peer leadership, supervisory support, and community liaison in the implementation of village-based services. A large-scale experiment will be fielded to test the demographic impact of this approach.
