An assessment of malaria diagnostic capacity and quality in Ghana and the Republic of Benin.

Background: In malaria-endemic countries, the absence of parasitological confirmation of malaria infection potentially results in overtreatment of non-malaria febrile illness with antimalarial drugs; this may lead to healthcare workers (HCW) missing other treatable illness or wastage of resources. This paper presents results from nationally representative assessments of malaria diagnostic accuracy, quality and capacity in Ghana and the Republic of Benin.

Methods: Cross-sectional surveys were conducted in December 2012 among a representative sample of health facilities (n=30 per country), using a modified service provision assessment, followed by HCW observations and interviews.

Distribution of human Oesophagostomum bifurcum, hookworm and Strongyloides stercoralis infections in northern Ghana.

A cross-sectional study was carried out in 216 randomly selected, representative rural villages in the northeastern part of Ghana from March 1995 to May 1998. Inhabitants of randomly selected households, stratified by age and gender, were included. The geographical position of villages was recorded with a global positioning system (GPS).

Determining the prevalence of Oesophagostomum bifurcum and Necator americanus infections using specific PCR amplification of DNA from faecal samples.

Until recently infection of humans with Oesophagostomum bifurcum was regarded as a rare zoonosis. But in northern Togo and Ghana its prevalence is 50% or more in certain villages. Diagnosis is hampered by the fact that the eggs of O.

Ultrasonographic detection and assessment of preclinical oesophagostomum bifurcum-induced colonic pathology.

In northern Ghana and Togo, Oesophagostomum bifurcum infects an estimated 250,000 people, as determined by cultures of stool samples. The juvenile stages of the helminth develop within colonic wall nodules, causing Dapaong tumor or multinodular disease, at the rate of 1 case per week at Nalerigu Hospital in Ghana. Our aim was to discover whether suspected colonic-wall pathology is ultrasonographically visible in asymptomatic individuals living in the area where O.

Prevalene of perimenstrual symptoms.

The purpose of this study was to determine the prevalence of perimenstrual symptoms (PMS) in a free-living population of US women and to determine if prevalence estimates varied with parity, contraceptive status, characteristics of the menstrual cycle, and selected demographic variables. We identified all households from a census listing for five southeastern city neighborhoods that offered variation in racial composition and socioeconomic status. We ascertained all households in which there was one nonpregnant woman between the ages of 18 and 35 years per household.
