The medial breast margin sign: A new sign of pectus excavatum in adult females and comparison with classic signs.

Introduction: Pectus excavatum (PX) denotes a concavity of the sternum and is the most common chest wall deformity. Many characteristic signs have been described on frontal chest radiographs including increased density of the inferomedial right lung, blurring of the right heart border, steeply angled anterior ribs, horizontal posterior ribs, straight or convex left heart border and loss of silhouette of the descending thoracic aorta. These signs are often subtle and rarely all present in any individual.

A correlation study of the American Shoulder and Elbow Society Score and the Oxford Shoulder Score with the use of regression analysis to predict one score from the other in patients undergoing reverse shoulder joint arthroplasty for cuff tear arthropathy.

Background: More than 30 different scoring systems are available for evaluating outcomes of shoulder surgery. Unfortunately, given the multitude of scoring systems, there is no objective method to compare results between studies when different scoring systems are utilized.

Methods: We compared the American Shoulder and Elbow Society score (ASES) and the Oxford Shoulder Score (OSS) in patients undergoing reverse shoulder arthroplasty for cuff tear arthropathy.

Torsion of parietal-peritoneal fat mimicking acute appendicitis: a case report.

Introduction: Infarctions of the greater omentum and appendices epiploicae are uncommon, but well documented causes of acute abdominal pain. We present a rare case of torted fat on the parietal peritoneum over the anterior abdominal wall, mimicking clinical signs of acute appendicitis, which was diagnosed at laparoscopy. We are aware of only two other similar reported cases, both of which were diagnosed at the time of laparotomy.
