BACKGROUND The question was asked whether patients who discontinue one serotonin selective reuptake inhibitor (SSRI) because of side effects can be treated successfully with another SSRI. METHOD 113 patients with major depression who had discontinued fluoxetine because of side effects were enrolled in an open, multicenter, 8-week study designed to(More)
BACKGROUND Access to "safe" water and "adequate" sanitation are emphasized as important measures for schistosomiasis control. Indeed, the schistosomes' lifecycles suggest that their transmission may be reduced through safe water and adequate sanitation. However, the evidence has not previously been compiled in a systematic review. METHODOLOGY We carried(More)
In vitro studies have shown that fluoxetine and paroxetine are more potent inhibitors of cytochrome CYP2D6 than sertraline. The pharmacokinetics of desipramine when coadministered with the selective serotonin reuptake inhibitors (SSRIs) paroxetine and sertraline were studied in 24 healthy male volunteers (CYP2D6 extensive metabolizers). Desipramine (50(More)
Schistosomiasis is a disease caused by infection with blood flukes of the genus Schistosoma. Transmission of, and exposure to, the parasite result from faecal or urinary contamination of freshwater containing intermediate host snails, and dermal contact with the same water. The World Health Assembly resolution 65.21 from May 2012 urges member states to(More)
Porcine cysticercosis is an emerging agricultural problem in sub-Saharan Africa. This has been documented primarily through cross-sectional studies, however detailed knowledge of the transmission dynamics of this disease in sub-Saharan Africa is lacking. This study aims to describe seasonal variations in sero-prevalence of antigen ELISA positive porcine(More)
The pharmacokinetic interactions of sertraline and fluoxetine with the tricyclic antidepressant desipramine were studied in 18 healthy male volunteers phenotyped as extensive metabolizers of dextromethorphan. Concentrations in plasma were determined after 7 days of desipramine (50 mg/day) dosing alone, during the 21 days of desipramine and selective(More)
One hundred patients with major depression who had discontinued fluoxetine because of side effects were enrolled in a multicenter, open, 8-week study of sertraline. After a washout period of at least 3 weeks following fluoxetine discontinuation and an additional 1-week, single-blind, placebo washout period, patients began treatment with 50 mg sertraline(More)
BACKGROUND Taenia solium infections are mostly endemic in less developed countries where poor hygiene conditions and free-range pig management favor their transmission. Knowledge on patterns of infections in both human and pig is crucial to design effective control strategies. The aim of this study was to assess the prevalence, risk factors and spatial(More)
BACKGROUND The pork tapeworm, Taenia solium, and associated human infections, taeniasis, cysticercosis and neurocysticercosis, are serious public health problems, especially in developing countries. The World Health Organization (WHO) has set goals for having a validated strategy for control and elimination of T. solium taeniasis/cysticercosis by 2015 and(More)
Taenia solium is found throughout sub-Saharan Africa and co-endemic with schistosomiasis in many regions. Taenia solium leads to taeniosis and neurocysticercosis - the leading cause of preventable epilepsy globally. This study aimed to assess the effects of the National Schistosomiasis Control Programme on prevalence of taeniosis and porcine cysticercosis(More)
