[Contribution of Holter ECG in the etiologic diagnosis of the ischemic stroke in Brazzaville, Congo].

To determine the prevalence of the rhythmic disorders during ischemic stroke, and to identify the predictive factors of paroxysmal atrial fibrillation (PAF). It was about a cross-sectional study, descriptive and analytical, conducted to Brazzaville between january 2012 and december 2016. It related to a consecutive series of 267 patients victims of a transient ischemic attack (n = 17) or ischemic stroke (n = 250), documented by cerebral tomodensitometry or brain MRI.

Association of vitamin D status with multiple sclerosis in a case-control study from Morocco.

Background: Growing evidence suggests that hypovitaminosis D contributes to the pathogenesis of multiple sclerosis (MS).

Objective: This study aimed to evaluate whether vitamin D levels are associated with having MS and some of its characteristics in the Moroccan population.

Methods: Using liquid chromatography-tandem mass spectrometry, the 25(OH)D metabolite was measured to quantify vitamin D serum levels (DSLs) in 113 patients with MS and 146 healthy controls matched for gender and age.

Vitamin D deficiency and its role in neurological conditions: A review.

This review exposes recent advances on the role of vitamin D, cholecalciferol, a secosteroid, in the central nervous system. In humans, vitamin D arises from cutaneous transformation of 7-dehydrocholesterol under the effect of UVB exposure or from food intake. Vitamin D has an immunomodulatory role through its anti-inflammatory and anti-autoimmune actions.

Polysomnography as a diagnosis and post-treatment follow-up tool in human African trypanosomiasis: a case study in an infant.

Gambian (Trypanosoma brucei gambiense) human African trypanosomiasis (HAT) evolves from the hemolymphatic stage 1, treated with pentamidine, to the meningoencephalitic stage 2, often treated with melarsoprol. This arseniate may provoke a deadly reactive encephalopathy. It is therefore crucial to diagnose precisely the stages of HAT, especially when clinical and biological examinations are doubtful.
