ABSTRACT
CONTEXT: This study was conducted at the National Tuberculosis Center in Burkina Faso from October 2007 through May 2008. OBJECTIVE: Our objective was to compare the diagnostic performance of three staining methods: Kinyoun, auramine O, and Ziehl-Neelsen. METHODS: Ziehl-Neelsen staining served as the reference method to assess the diagnostic performance of Kinyoun and auramine O staining. In all, 616 sputum smears from 233 patients were read with each method to detect acid-fast bacilli. SPSS was used for data analysis. RESULTS: The results of auramine O staining showed positive diagnoses in 15.9% of the samples; sensitivity was 100%, specificity 95.6%, and the positive and negative predictive values 75.7% and 100% respectively. Kinyoun staining produced a positive diagnosis rate of 12%, sensitivity of 96.4%, specificity of 99.5%, and positive and negative predictive values of 96.4% and 99.5%. CONCLUSION: Our study indicates that auramine O staining had a better sensitivity for detecting acid-fast bacilli than Kinyoun staining. Accordingly, the use of auramine O staining should increase the detection rate for pulmonary tuberculosis in Burkina Faso.

To investigate the sector of food sold in the streets of Bobo-Dioulasso and identify relevant information for action, a survey on knowledge and practices of street food vendors and consumers was conducted in June 2005. Data have been collected in 928 street food selling posts. Structured questionnaires were used to collect data from 874 street vendors and 2474 consumers. Street food sites are concentrated in places where administration and trade activities are usually running. The street food seller is a married and illiterate woman of 32 years old. Cereals (48.5%), meat (33.9%), milk (9.6%) and fruits (4.4%) are the basic consumables. The street food consumer is a non married man, 27 years old working in profit-making activity. Consumers use many criteria to choose the place to eat, at times or permanently. The street food sector represents a source of income and induces change in household eating habits. Street food in Bobo-Dioulasso needs to be better organised, by using an holistic approach that involves all the actors.

The purpose of this survey was to evaluate the experience of physicians in Burkina Faso with haemoglobinopathy (particularly sickle cell disease). Survey findings showed that these pathologies were encountered in daily medical practice but that resources necessary to insure proper prevention, follow-up and treatment were insufficient. Practitioners expressed the need for better continuous medical education and for information campaigns to familiarize the public.

Cette etude evalue l'experience medicale vis-a-vis des hemoglobinopathies et en particulier des syndromes drepanocytaires au Burkina Faso. Un questionnaire a reponses a choix multiple et a reponses libres a ete utilise. L'etude montre que ces pathologies sont rencontrees dans la pratique quotidienne; mais que les moyens mis a disposition des medecins pour la prevention; le suivi et le traitement de celles-ci sont limites. Une amelioration dans la formation medicale continue et dans l'information du public ont ete souhaitees par les medecins interroges

BACKGROUND: It is known that malnutrition in childhood interacting with infectious diseases contributes to increase mortality. In Burkina Faso, infectious pathologies and malnutrition are public health problems. We examined the impact of malnutrition status, using the Weight-for-age (WA) index, on mortality of children hospitalized for infectious diseases. METHODS: This retrospective study uses a systematic sample derived from the year 1999 hospital register. In total data of 1573 children from 0 to 59 months were analyzed. The association between mortality and dependent variables was measured by relative risks (RR) in univariate analysis. A logistic regression was realized and attributable risk percent (etiologic fraction among exposed) of death was calculated. RESULTS: The total intra-hospital lethality amounted to 15.3%. Age, diagnosis, type of care recourse and malnutrition (low WA index) on admission were associated to mortality. The logistic regression model confirmed the high risks of deaths for young children (0-11m), children in malnutrition (low WA index) and those with severe malaria. The attributable risk percent of death indicates that, 87% of deaths are statically attributable to severe malnutrition (WA Z-score<=-3) and 64.3% of deaths are statically attributable to moderate malnutrition (WA Z-score]-3, -2]). CONCLUSION: Nutritional status evaluation would allow to select children at risk and reduce mortality by including nutritional intervention in standard treatment of children hospitalized for infectious diseases.
