Intracranial hemorrhages in patients with COVID-19: a systematic review of the literature, regarding six cases in an Amazonian population.

Background:  Coronavirus disease 2019 (COVID-19) has emerged as a public health emergency worldwide, predominantly affecting the respiratory tract. However, evidence supports the involvement of extrapulmonary sites, including reports of intracranial hemorrhages.

Objective:  To describe six original cases and review the literature on intracranial hemorrhages in patients diagnosed with COVID-19 by molecular methods.

TCD assessment in fulminant hepatic failure: Improvements in cerebral autoregulation after liver transplantation.

Introduction And Objectives: Acute liver failure, also known as fulminant hepatic failure (FHF), includes a spectrum of clinical entities characterized by acute liver injury, severe hepatocellular dysfunction and hepatic encephalopathy. The objective of this study was to assess cerebral autoregulation (CA) in 25 patients (19 female) with FHF and to follow up with seventeen of these patients before and after liver transplantation.

Patients And Methods: The mean age was 33.

Cerebral Vasculopathy in Children With Sickle Cell Disease in an Amazonian Population.

Sickle cell disease is the most prevalent hereditary disease in the country. The aim of this study was to use transcranial Doppler as a screening method for identifying cerebral vasculopathy in children with sickle cell disease. An epidemiologic, descriptive, and cross-sectional study was conducted.

Detection of Cerebral Vasculopathy by Transcranial Doppler in Children With Neurofibromatosis Type 1.

Neurofibromatosis type 1 is characterized by nerve sheath neurofibromas associated with a number of additional clinical features, including cerebrovascular disease. The aim of this study was to use transcranial Doppler as a screening method for identifying cerebral vasculopathy in children with neurofibromatosis type 1. Forty children with neurofibromatosis type 1, aged 5 to 18 years old, were examined by transcranial Doppler.

Psychiatric symptoms may contribute to poor quality of life in adolescents with migraine.

Background: The impact of migraine on quality of life (QOL) can be aggravated by other comorbid factors. The aim of the present study was to assess the differences in the QOL of adolescents with chronic migraine, episodic migraine, and healthy adolescents, and whether the differences in QOL among the diagnostic groups were associated with the presence of self-reported psychiatric symptoms, such as depression and anxiety.

Methods: A total of 157 adolescents (aged 15-19 years old) were included in the study.
