The 2008 food price crisis negatively affected household food security and dietary diversity in urban burkina faso

Although the 2008 food price crisis presumably plunged millions of households into poverty and food insecurity, the real impact of the crisis has rarely been documented using field data. Our objective was to assess the consequences of this crisis for household food insecurity and dietary diversity in urban Burkina Faso. Two cross-sectional surveys were conducted among randomly selected households in Ouagadougou in July 2007 (n = 3017) and July 2008 (n = 3002). At each round, food insecurity assessed by the Household Food Insecurity Access Scale (HFIAS), the Dietary Diversity Score of an index-member of the household (IDDS = number of food groups consumed in the last 24 h), and food expenditure were collected. Food prices of the 17 most frequently consumed food items were recorded throughout the study area. Food prices at local markets increased considerably between 2007 and 2008, especially those of fish (113%), cereals (53%), and vegetable oil (44%), increasing the household monthly food expenditure by 18%. Thirty-three percent of households were food secure in 2007 and 22% in 2008 (P = 0.02). Individuals consumed fewer fruits and vegetables, dairy products, and meat/poultry in 2008 than in 2007 (mean IDDS = 5.7 ± 1.7 food groups in 2007 vs. 5.2 ± 1.5 in 2008; P < 0.0001). Differences in IDDS and HFIAS between the 2 y were even more marked after adjustment for confounding factors and food expenditure. Food security and dietary diversity significantly decreased between 2007 and 2008, whereas food prices increased. Households increased their food expenditure, but this was not sufficient to compensate the effects of the crisis.     

Dent's syndrome. Nephrology follow-up of four patients of the same family

Dent's syndrome is a rare inherited tubulopathy. Factors influencing renal function in this disease are not well known. The aim of our study is to investigate the evolution of the Dent's syndrome in renal plan. The study was retrospective and conducted in 2006, concerning four brothers. The genetic defect was a mutation S244L missense in exon 6 of gene CLCN5. Various parameters were studied. Patients were 8.5 to 21-years-old at the beginning of the follow-up. Two of them had chronic renal insufficiency (CRI) which evolved, at least 7 years of moderate to terminal stage. Tubular signs were made of hypokalemia, hypercalciuria, hypophosphatemia and proteinuria mostly β2 microglobulin. Improvement of these abnormalities was obtained with symptomatic treatment which has not always been well tolerated. A case of beginner nephrocalcinosis was observed. There was size and weight delay at the beginning of patient monitoring. Dent's syndrome may be complicated by CRI. It seems to appear in the second decade of life and hypercalciuria would contribute to it. Our CRI patients had significant bone disease. The hypercalciuria and proteinuria are factors over which we try to act. Clinical trials are needed to evaluate the efficacy of treatment on the reduction of CRI or its progression by reducing these factors in patients with Dent's syndrome.

Ability of mothers to diagnose fever and anaemia in their young children, in a malaria-endemic region of West Africa

The rapid and correct diagnosis of fever and anaemia at the household level is a prerequisite for the successful management and control of life-threatening disease among young children, particularly in malaria-endemic areas of Africa. The ability of mothers to diagnose fever and anaemia in their young children has recently been explored, as part of a large, birth-cohort study in rural, north-western Burkina Faso. During a cross-sectional survey in six villages, 345 children aged, <3 years and their mothers were investigated. Each mother was asked if she considered her child to be febrile and/or anaemic before that child's temperature and haematocrit were measured, with an electronic thermometer and portable centrifuge, respectively. The recorded prevalences of fever (> or =37.5 degrees C) and anaemia (haematocrit, <25%) in the children were 12.2% and 21.4%, respectively. The mothers' diagnoses had a sensitivity of 76.2% [95% confidence interval (CI)=60.6%-88.0%] for fever and 4.1% (CI=0.8%-11.4%) for anaemia, with corresponding specificities of 87.1% (CI=82.8%-90.7%) and 95.9% (CI=92.9%-98.0%). Mothers in rural Africa appear to be fairly accurate in detecting fever in their children but less accurate in detecting anaemia. While malaria control needs to employ a mix of preventive and curative measures, anaemia control will benefit from community-based malaria-control measures as well as broader approaches addressing the nutritional status of young children.     

Mature posterior fossa teratoma mimicking infratentorial meningioma: a case report

Intracranial teratomas are congenital neoplasms mostly diagnosed in the pediatric hood and usually involve supratentorial midline structures. These teratomas, especially those involving the posterior fossa are an uncommon and representing less than 0.5% of all intracranial tumors. We report a case of mature posterior fossa teratoma in an adult patient diagnosed in the 4th decade of life. This lesion was taken for a huge infratentorial meningioma.     

In Vivo Efficacy and Parasite Clearance of Artesunate + Sulfadoxine–Pyrimethamine Versus Artemether–Lumefantrine in Mali

Although artemisinin resistance has yet to be reported in Africa, surveillance of the efficacy of artemisinin-based combination therapies (ACTs) is warranted. Here, the efficacy of artesunate + sulfadoxine–pyrimethamine (AS+SP) and artemether–lumefantrine (AL) was evaluated in Mali. Randomized open-label comparative in vivo assay of AS+SP versus AL were carried out using the 28-day follow-up World Health Organization protocol. Patients with uncomplicated falciparum malaria and at least 6 months of age were recruited between October 2010 and January 2014. A subset of these patients was selected to measure Plasmodium falciparum clearance time. Polymerase chain reaction-corrected adequate clinical and parasitological responses were 100% for AS+SP and 98.2% for AL with no significant difference (P = 0.06). The reinfection rates were comparable (P = 0.63) with 8.0% for AS+SP and 12.6% for AL. Individuals under 8 years were more susceptible to treatment failure (relative risk = 1.9; 95% confidence interval = 1.2, 3.3). Median parasite clearance half-life was 1.7 hours (interquartile range [IQR] = 1.3–2.2) for AS+SP and 1.9 hours (IQR = 1.5–2.5) for AL with no statistically significant difference (P = 0.24). Efficacy of AS+SP and AL was high. This study provides baseline information on parasite clearance half-lives after ACT treatment, particularly AS+SP, in Mali.
