A Scoring System That Predicts Difficult Lipoma Resection: Logistic Regression and Tenfold Cross-Validation Analysis.

Introduction: Most lipomas are readily dissected and removed. However, some cases can pose surgical difficulties. This retrospective study sought to identify clinical and radiological risk factors that predict difficult lipoma resection and can be used in a clinically useful scoring system that predicts difficulty preoperatively.

Multidetector-Row Computed Tomographic Analysis of the Superficial Palmar Branch of Radial Artery Perforator Flaps.

Background: Soft-tissue defects in the hand and digits can be effectively covered by using the free superficial palmar branch of the radial artery (SPBRA) flap, which is harvested from the radial volar wrist. Because previous anatomical studies on this flap are limited, multidetector-row computed tomographic angiography of the upper limbs was conducted to characterize the three-dimensional anatomical structure of the SPBRA and its perforators in living patients.

Methods: This retrospective anatomical study was conducted from 2014 to 2019.

Prompt Procedures Have a Great Impact on the Consequences of Asiatic Black Bear Mauling.

Introduction: Although bear-inflicted human injuries are rare and the mortality rate of the injuries is usually not high, the chances of bear-human interactions have been increasing, with fatal cases being reported in Japan every year. The aim of this study was to report a series of bear-inflicted injuries and discuss their management and severity.

Materials And Methods: A retrospective study was performed at the emergency and critical care center of Aizu Chuo Hospital, a tertiary care center in Japan, from May 2013 to September 2015.

A case of obesity hypoventilation syndrome with respiratory failure that improved with abdominoplasty.

We report on a 70-year-old man with severe respiratory failure caused by obesity hypoventilation syndrome due to abdominal adiposis. Obesity hypoventilation syndrome is a severe condition that is diagnosed when all of the following criteria are satisfied: body-mass index >30 kg/m(2); apnea hypopnea index >30; PaCO2 >45 mm Hg (in the daytime); and marked daytime somnolence. Abdominoplasty, which is generally used for abdominal laxness, striae, and rectus muscle diastases and for women in the postpartum period, was performed for this patient to facilitate ventilator weaning and produced a satisfactory result.
