Sudden cardiovascular collapse during the TUL procedure: A case series.

Although ureteroscopy is a minimally invasive procedure, there have been reports of some minor and major complications, from self-limited to complicated events such as ureteral avulsion, urosepsis, and even death due to cerebrovascular accidents and deep vein thrombosis. Herein, we aim to report seven patients who presented with cardiovascular collapse during ureteroscopy in a 19-year period from January 2002 to January 2021.

Evaluation and Comparison of Mucormycosis Patients' Features Undergoing Functional Endoscopic Sinus Surgery Prior to and during the COVID-19 Pandemic: A Case-Control Study.

Background: Rhinocerebral mucormycosis is a serious invasive fungal infection that is one of the most aggressive and lethal of invasive mycoses. The coronavirus disease (COVID-19) has been linked to immune dysregulation, and patients with COVID-19 have been reported to be at risk for developing invasive fungal infections. This study is conducted to evaluate the concurrence of mucormycosis among COVID-19 patients.

Comparison of lidocaine, huffing maneuver and combination of both in prevention fentanyl induced cough before induction of anesthesia: a double-blind, prospective, randomized placebo-controlled study.

Background: Intravenous bolus injection of fentanyl has been frequently reported to be associated with cough reflex during patient anesthesia. However, the search for the most effective protocol continues. This study aimed to compare the effect of reducing cough reflex after injection of fentanyl in a fusion protocol by combining the injections of lidocaine and Huffing maneuver and comparing with a placebo control group, before anesthesia induction.

A simple way to achieve the routine position for phacoemulsification in a patient with marked thoracic kyphosis.
