Anthropometric measurements: effect of CT depth of pretracheal soft tissue on tracheotomy tube selection.

Background And Purpose: Tracheotomy is a commonly performed procedure; however, in the obese, it can be associated with a high morbidity and mortality, partially due to accidental decannulation. We hypothesize that a simple and rapid measurement of the DPST on CT will accurately predict those patients in need of an extended-length tracheotomy tube.

Materials And Methods: A retrospective review of the electronic health record and available CT imaging of the neck was performed for all patients who underwent tracheotomy at a tertiary care center.

Clinical significance of epicardial fat measured using cardiac multislice computed tomography.

Cardiac adiposity defined as increased epicardial adipose tissue and massive deposits of fat within the atrial septum (lipomatous hypertrophy) is seen in overweight persons and is associated with coronary artery disease (CAD), atrial arrhythmias, and increased risk of left ventricular free wall rupture after acute myocardial infarction. Unlike subcutaneous fat, epicardial fat is metabollically active and produces hormones, cytokines, and other vasoactive substances that work systemically or locally to alter vascular endothelial function and may be implicated in the pathogenesis of CAD. The aim of the study was to assess the feasibility of measuring epicardial fat volume (EFV) and identify its clinical correlates using (64-slice) multislice computed tomography (MSCT).

Management of malignant, mixed mesodermal tumors of the uterus.

Forty-two patients with malignant, mixed mesodermal tumors of the uterus were identified by retrospective chart review. Only 2 patients were premenopausal at the time of diagnosis. Six of the patients had previously received pelvic radiotherapy.
