Background: Harvey Cushing and collaborators created the first society of neurosurgeons in 1920, in the United States of America, the Society of Neurological Surgeons. In 1955, the World Federation of Neurosurgical Societies (WFNS) was created in Switzerland to improve neurosurgical care globally through the scientific cooperation of members. The performance of neurosurgical associations today is fundamental to discuss diagnostic methods and therapeutic approaches, transforming modern medicine.

Introduction: The reorganization of healthcare systems to face the COVID-19 pandemic has led to concerns regarding psychological distress of healthcare workers, and training requirements of physician residents.
Objective: To assess the influence of COVID-19 pandemic on depression, anxiety, burnout and training schedules of residents.
Methods: Two independent cross-sectional studies (the first in November 2019 [control], the second in June 2020, during the first wave of COVID-19 pandemic) enrolling physician residents from Brazil, using online surveys.
Background: Gliosarcoma (GS) is classified as an IDH-wild-type variant of glioblastoma (GBM). While GS is already an unusual presentation of GBM, IDH1-mutant cases are especially rare. We present an IDH1-mutant primary intraventricular GS case report and a systematic review of the molecular profile in GS correlating to the prognostic and pathogenesis of IDH1/2 mutations.

They are more common in men, with a mean age of 36 years, and rarely affect the supratentorial region and, when present in this topography, do not have meningeal impairment. Diagnosis by the radiologic and histopathologic study is difficult, since they are rare and, therefore, forgotten diagnosis, besides they are differential diagnoses with other supratentorial neoplasms.

Case Description: A 50-year-old female presented with acute sphincter dysfunction and paraparesis attributed to T2-T4 OPLL.
Background: The health benefits associated with moderate wine consumption, as with ethanol and phenolic compounds, include different mechanisms still little understandable.
Aim: Evaluate glycemic and weight variations, and the deposit of triglycerides, cholesterol and liver glycogen with red wine consumption.
Methods: 60 ApoE knockout mice were divided into three groups of 20: Wine Group (WG), Ethanol Group (EG) and Water Group (WAG).
Objective: to evaluate the effect of the Euphorbia tirucalli hydroalcoholic extract (ETHE) on the development of Ehrlich Tumor, in its ascitic form.
Methods: we intraperitoneally inoculated 15 Swiss mice with 10.44 x 107 cells of Ehrlich Tumor and divided them in two groups one day after: ETHE Group (eight mice), treated with a dosage of 125 mg/kg/day of EHTE for five days; and Control Group (seven mice), treated only with 0.
Purpose: To evaluate wound healing in rats by using low-level laser therapy (LLLT) associated with hydrocolloid occlusive dressing.
Methods: Forty male, adult, Wistar rats were used, distributed into four groups: LG (received 2 J/cm² of laser therapy); HG (treated with hydrocolloid); LHG (treated with 2 J/cm² of laser therapy and hydrocolloid); and the CG (treated with 1 mL of 0.9% saline).
Purpose: To analyze microscopically the effects of different concentrations of oxygen in the lungs of rats.
Methods: There were 20 rats distributed in three experimental groups (concentration of oxygen to 40%, 70% and 100%) and a control group. The animals were exposed to the oxygen in a chamber of acrylic during three days and after exposition, the animals were submitted to median thoracotomia to remove the lungs.
Background: The use of plants in the prevention and treatment of disease is age-old practice. The aveloz (Euphorbia tirucalli) is a plant native of Africa and has been associated with antimicrobial, antiulcers, anticarcinogenic, antiviral, healing, anti-helminthic, antisiphilitic effects.
Aim: To analyze the effect of the crude extract of Euphorbia tirucalli L.
Purpose: To evaluate the effects of crude extract of Euphorbia tirucalli in cutaneous wound healing.
Methods: A total of 20 Swiss mice were randomly divided into two groups, aveloz (GA) and control (CG), and each group was further divided into two subgroups based on the deaths scheduled for the 7th and 14th days after surgery. The animals underwent a resection of cutaneous fragment with 1cm in diameter on the dorsum; the GA was applied in each animal on the subsequent days, 0.
Purpose: To evaluate the healing process of rat traumatic liver lesion corrected with the use of 2-octyl cyanoacrylate adhesive, compared to the use of biologically absorbable chromed catgut thread suture.
Methods: Thirty mail adult rats were divided into two groups (15 per group) according to the used method for liver lesion correction as follows: adhesive group (AG), and catgut group (CG); each group being divided into three subsets of five animals (7th, 14th, and 21st day), respectively, according to post-surgery evaluation. All animals were submitted to homogeneous lesion applying synthetic bonding to AG and using chromed catgut suture to CG for lesion correction.
