Brazilian autoimmune encephalitis network (BrAIN): antibody profile and clinical characteristics from a multicenter study.

Background: The frequency of antibodies in autoimmune encephalitis (AIE) may vary in different populations, however, data from developing countries are lacking. To describe the clinical profile of AIE in Brazil, and to evaluate seasonality and predictors of AIE in adult and pediatric patients.

Methods: We evaluated patients with possible AIE from 17 centers of the Brazilian Autoimmune Encephalitis Network (BrAIN) between 2018 and 2022.

Studies on functional and morphological aspects in human multinodular simple goiter tissues.

Samples from 2 different locations within the same euthyroid multinodular goiters (SMG) and normal (N) human thyroids were assayed for their content of DNA, thyroglobulin (Tg), and stable iodine (1), and determined the response of adenosine 3',5'-cyclic monophosphate (cAMP) to TSH and NaF. Quantitative morphological estimation of histological components in the thyroid was performed and correlated with functional parameters. Regardless the zonal evaluation, in SMG the mean (± SD) DNA content (⧎g/mg tissue) (1.

Colon perforation following percutaneous nephrolithotomy.

Between February 1984 and 1986, 285 patients underwent percutaneous nephrostomy placement followed by track dilation and calculi removal. Although percutaneous colonic perforation is rare, we report a case consequent to this procedure. The patient had a good outcome after surgical management of the damaged colon.
