Systematic Review: Estimation of global burden of non-suppurative sequelae of upper respiratory tract infection: rheumatic fever and post-streptococcal glomerulonephritis.

Objectives: To establish the incidence of post-streptococcal glomerulonephritis (PSGN) and acute rheumatic fever, the prevalence of rheumatic heart disease (RHD), and to estimate morbidity and mortality caused by these diseases globally.

Methods: Systematic literature review and review of World Health Organisation (WHO) vital registration data (VRD).

Results: Incidence and prevalence of rheumatic fever and RHD show very significant global variation.

Incidence and predictors of acute mountain sickness among trekkers on Mount Kilimanjaro.

We investigated the incidence of AMS amongst a general population of trekkers on Mount Kilimanjaro, using the Lake Louise consensus scoring system (LLS). Additionally we examined the effect of prophylactic acetazolamide and different ascent profiles. Climbers on 3 different ascent itineraries were recruited.

Manganese-enhanced magnetic resonance imaging (MEMRI) of rat brain after systemic administration of MnCl₂: hippocampal signal enhancement without disruption of hippocampus-dependent behavior.

Manganese (Mn(2+))-enhanced magnetic resonance (MR) imaging (MEMRI) in rodents offers unique opportunities for the longitudinal study of hippocampal structure and function in parallel with cognitive testing. However, Mn(2+) is a potent toxin and there is evidence that it can interfere with neuronal function. Thus, apart from causing adverse peripheral side effects, Mn(2+) may disrupt the function of brain areas where it accumulates to produce signal enhancement and, thereby, Mn(2+) administration may confound cognitive testing.
