[Clinical appearance and scalable profile Thiamine deficiency in prison in Guinea: study of thirty-eight observations]. / Aspect clinique et profil évolutif de la carence en thiamine en milieu carcéral en Guinée : étude de trente-huit observations.

Cardiovascular and neurological manifestations associated with thiamine deficiency in Guinean prisons are common but not reported.We performed a prospective study of 38 cases related to vitamin B1 deficiency over a period of 4 years. In this population, the literature of traditional data gathered: frequency peak after thirty (92.6%) and clear representation male (sex ratio M/F: 18/1). The clinical symptomatology remains essentially dominated by sensorimotor polyneuropathy and pure sensory (52.2%), overall heart failure (31.5%) and to a lesser degree by Gayet Wernicke's encephalopathy (7.8%) and shoshin beriberi with severe evolution (5.2%). The study of nutritional status by body mass index (BMI) of the World Health Organization, by the criteria of Detsky and biological markers including albumin, shows that these patients are severely malnourished.

Acute parasitic and other infectious myelopathies in the tropics: 26 cases at the University Hospital in Conakry.

In tropical countries, laboratory-confirmed diagnostic certainty of parasitic and other infectious causes of acute myelopathy is difficult because of a shortage of medical professionals and consulting delays. We performed a retrospective study of 168 patients hospitalized for spinal disorders between 2007 and 2013 and identified 26 diagnosed with acute non-compressive myelopathy of presumed sudden onset. An parasitic or other infectious cause was established for all. A preliminary clinical infection preceding the development of neurologic signs was reported for 22 patients (84.6 %). Neurological signs were limited to the existence of a progressive sensorimotor symptomatology with sphincter disorders.
