Differential Diagnosis or Etiology: A Case Report on Amyotrophic Lateral Sclerosis-like Neuropathy Associated with HIV Infection.

Background: Retroviruses are described as a risk factor for chronic neuropathy. However, it is still unknown if they can work as amyotrophic lateral sclerosis triggers. Over the years, some cases of this association have been described with heterogenous disclosures.

Lead-DBS: an additional tool for stereotactic surgery.

Objective: Use Lead-DBS software to analyze stereotactical surgical outcome of an operated population and demonstrate that small target deviations do not compromise the stimulation of desired structures, even with small amperages.

Methods: Image exams of patients submitted to deep brain stimulation for movement disorders treatment were processed in Lead-DBS software. Electrode stereotactic coordinates were subtracted from the planned target and those deviations, compared among different anatomical targets and sides operated firstly and secondly.

Complicated Cerebral Venous Thrombosis During the First Trimester of Pregnancy.

Pregnancy and puerperium are known conditions associated with venous thrombotic events, which may present atypically in cases such as cerebral venous thrombosis. Since these are uncommon events, there is a paucity of reports and protocols for the management of these patients, resulting in no clear consensus in the literature. We report a case of a woman, nine weeks pregnant, who developed thrombosis of the right transverse and superior sagittal sinuses.

Resting state connectivity patterns with near-infrared spectroscopy data of the whole head.

Resting state cerebral dynamics has been a useful approach to explore the brain's functional organization. In this study, we employed graph theory to deeply investigate resting state functional connectivity (rs-FC) as measured by near-infrared spectroscopy (NIRS). Our results suggest that network parameters are very similar across time and subjects.
