Age- and Sex-Specific Nomographic CT Quantitative Plaque Data From a Large International Cohort.

Background: With growing adoption of coronary computed tomographic angiography (CTA), there is increasing evidence for and interest in the prognostic importance of atherosclerotic plaque volume. Manual tools for plaque segmentation are cumbersome, and their routine implementation in clinical practice is limited.

Objectives: The aim of this study was to develop nomographic quantitative plaque values from a large consecutive multicenter cohort using coronary CTA.

Outcomes of Surgical Tracheostomy on Mechanically Ventilated COVID-19 Patients Admitted to a Private Tertiary Hospital in Tanzania.

Objectives:  The coronavirus disease 2019 (COVID-19) pandemic has resulted in an increase in the number of patients necessitating prolonged mechanical ventilation. Data on patients with COVID-19 undergoing tracheostomy indicating timing and outcomes are very limited.

Xanthogranulomatous cholecystitis complicated by a cholecysto-colonic fistula and liver abscesses.

A 57-year-old male presented to the emergency department with right upper quadrant pain and constitutional symptoms. Initial investigation revealed biliary sepsis with features of chronic cholecystitis, multiple liver abscesses and a fistulous connection between the gallbladder and colon. He was subsequently diagnosed with a cholecysto-colonic fistula, an unusual complication of biliary pathology, with an incidence of 0.
