COVID-19 pandemic decreased sleep quality of medical students.

Objective: Medical students are especially vulnerable to situations of poor sleep quality due to academic demands. The COVID-19 pandemic brought significant changes and high psychological stress, causing a great impact on this population. Here we aim to analyze the influence of the pandemic on the sleep quality of medical students.

Cholecystectomy before, simultaneously, or after ERCP in patients with acute cholecystitis: A protocol for systematic review and/or meta analysis.

Introduction: Cholecystectomy is the intervention of choice for treating acute cholecystitis; when conservative management does not work, it operates on the patient outside the critical condition. It can be performed together with or after endoscopic papillotomy through endoscopic retrograde cholangiopancreatography (ERCP) when it is concurrent with a situation of cholechodocolithiasis or when there is compression and consequent increase in pressure in the bile duct caused by a calculus jammed in the vesicular infundibulum (Mirizzi's syndrome), with or without jaundice, fever, and pain in the right hypochondrium (Charcot's Triad), which can progress to sepsis of biliary origin. This review aims to assess whether the timing of cholecystectomy (before or after ERCP) interferes with the postoperative period and clinical outcome in patients with acute cholecystitis.

Parkinsonism secondary to ventriculoperitoneal shunt in a patient with hydrocephalus.

Background: Parkinsonism secondary to the treatment of obstructive hydrocephalus due to stenosis of the cerebral aqueduct, with implantation of a ventricular peritoneal (VP) shunt is a rare complication, still poorly described and disseminated in the literature.

Case Description: A 38-year-old male presented a history of moderate-intensity daily headache, which deteriorated 2 months before admission, with no changes in the neurological examination. Magnetic resonance imaging showed hypertensive hydrocephalus associated with cerebral aqueduct stenosis.
