Prevalence of multiple sclerosis in Brazil: A systematic review.

Epidemiological studies of multiple sclerosis (MS) conducted in Latin America have revealed prevalence rates of this disease from low to medium. The aim of this study was to gather and analyze surveys on prevalence conducted in Brazil, noting its variability in different regions. Systematic review was held in electronic databases and manual search in abstracts concerning ECTRIMS, LACTRIMS and Brazilian Congress of Neurology. Nineteen studies made reference to prevalence rates that ranged from 1.36/100,000 to 27.2/100.000 inhabitants. More studies on the epidemiology of MS in Brazil will be needed for a better assessment of its prevalence and profile.

Epidermal nevus syndrome associated with adnexal tumors, spitz nevus, and hypophosphatemic vitamin D-resistant rickets.

The epidermal nevus syndrome is the association of epidermal nevi with abnormalities in other organ systems, most commonly the central nervous system, the skeletal system, and the eyes. We present a patient with epidermal nevus syndrome associated with hypophosphatemic vitamin D-resistant rickets and multiple adnexal and spindle cell tumors.
