Anthropometric Tomographic Study of the Hip in a Brazilian Regional Population.

 The present study aimed to determine the average hip anthropometry of a regional Brazilian population using measurements based on computerized axial tomography (CAT).  Retrospective, descriptive analysis of hip measurements from 200 abdominal CATs from patients visiting a medical center. The tests were selected at random to determine 30 previously defined anthropometric measurements.

Evaluation of the Intraobserver and Interobserver Agreements of the New AO/OTA Classification for Fractures of the Trochanteric Region and the Femoral Neck.

 In the present study, we investigated the intra and interobserver agreement of the new Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) classification for fractures of the proximal extremity of the femur.  One hundred hip radiographs were selected from patients who suffered fractures of the trochanteric region or femoral neck. Four orthopedists, fellowship trained hip surgeons, and four orthopedic residents evaluated and classified fractures according to the new AO/OTA system on two separate occasions.

Increased prevalence of femoroacetabular impingement on the elderly with fractures of the proximal femur.

Objectives: Femoroacetabular impingement (FAI) has been recently related to several pathologies, besides chondral injury and hip arthritis. We aim to investigate the prevalence of FAI morphology in an elderly cohort hospitalized due to a proximal femur fracture and compare these findings to a control group. We hypothesize that limited medial rotation due to FAI's morphology could increase stresses to the proximal femur, acting as a facilitating mechanism for fractures in this region.

Efficacy of Povidone-Iodine Nasal and Oral Antiseptic Preparations Against Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2).

Introduction: Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) is the pathogen responsible for the global pandemic of coronavirus disease 2019 (COVID-19). From the first reported cases in December 2019, the virus has spread to over 4 million people worldwide. Human-to-human transmission occurs mainly through the aerosolization of respiratory droplets.
