Background: Neuromyelitis optica spectrum disorders (NMOSD), is a rare autoimmune inflammatory disease of the central nervous system. Since the countries of Latin America (LATAM) show contrast in geographic, social, environmental factors, and genetic heterogeneity, the information about NMOSD epidemiology in the region allows a better understanding of the disease and its clinical outcome.
Objectives: To determine the prevalence, relative frequency (RF), and clinical characteristics of NMOSD in a multiethnic Venezuelan cohort of patients with demyelinating disorders.
Article Synopsis
- - The study aimed to evaluate vitamin D levels in patients with inflammatory joint diseases (IJD) such as rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis, along with its relationship to disease activity.
- - Out of 121 patients, 42.1% were found to be vitamin D deficient, with a notably higher deficiency rate among Arab patients (76.7%) compared to Jews (23%), highlighting significant ethnic disparities.
- - No correlation was observed between vitamin D levels and various assessed factors, but the results suggest that vitamin D testing should be a routine part of the assessment for patients with IJD. Further research is recommended to explore potential genetic factors affecting vitamin D receptors.
Objective: .Sclerodactyly with acroosteolysis (AO) and calcinosis are prominent features of systemic sclerosis (SSc), but the pathogenesis of these findings is poorly understood. Vitamin D and parathyroid hormone (PTH) have a crucial role in bone metabolism and resorption and may affect AO and calcinosis.

The regulator (Ministry of Health and health funds) mandates using fixed doses of infliximab as the first drug of choice and prohibits increased dosage. For other indications (e.

We present two cases of PAN limited to the calf and a review of the literature, based on a MEDLINE (PubMed) search of the English literature from 1980 to 2005, using the key words "vasculitis restricted to limbs", "polyarteritis nodosa", and "intravenous immunoglobulin". PAN limited to the calf muscles is a condition presenting with severe shin pain and walking difficulties.
