Pathogenetic factors fanning the flames of COVID-19 to cause rhino-orbito-cerebral mucormycosis: An observational study.

Background And Aims: Published studies on coronavirus disease 19 (COVID-19) associated rhino-orbito-cerebral mucormycosis (CAROCM) were primarily descriptive. Therefore, we aimed to identify features of COVID-19 that could predispose to CAROCM and explore the pathogenic pathways.

Patients And Methods: This retrospective hospital-based study was done during the first (March 2020 - January 2021) and the second (February 2021 - June 2021) waves of the COVID-19 pandemic.

Usefulness of routine preoperative testing: a prospective single-observer study.

Study Objective: The purpose of this study is to determine whether routine preoperative testing has a usefulness not previously recognized in a small preliminary study to decide if such a hypothesis might be worthy of testing in a larger study.

Design: Single-observer, prospective, observational study.

Setting: Tertiary-care referral center in South India that performs 11 preoperative tests on each patient.
