Chin necrosis as a consequence of prone positioning in the intensive care unit.

Pressure necrosis of the skin is a rarely reported avoidable complication of prone positioning that can be minimised by active collaboration between care teams. We report a case of pressure necrosis of the chin after prone ventilation in the intensive care setting. Such injuries pose a risk of infection, possible need for surgical intervention, and increased costs to the health care system.

Tendon to bone healing and its implications for surgery.

Entheses are complex structures which act to reduce stress concentrations between tendon and skeleton tissues. Understanding the development and function of the enthesis organ has implications for surgical repair, particularly in regards to healing and the regulation of tendon to bone engraftment. In this paper we review the development and function of entheses as well as the enthesis organ concept.

Torsion of an abdominal-wall pedunculated lipoma: a rare differential diagnosis for right iliac fossa pain.

Pedunculated lipomas arising from the peritoneal wall are a rare finding during abdominal surgery. These benign tumours of mesenchymal origin can arise anywhere in the body and are usually asymptomatic. We present a case of a torted, pedunculated parietal wall lipoma in the right iliac fossa that gave rise to a clinical diagnosis of appendicitis.

Thermal injuries caused by medical instruments: a case report of burns caused by a pulse oximeter.

Pulse oximeters have been widely used since the 1980s as they are considered to provide a safe, convenient, noninvasive method of estimating blood oxygen saturation. Initially used in the operating room by anesthesiologists, pulse oximetry has become ubiquitous in the healthcare setting. Although rare, serious burn injuries secondary to pulse oximetry have been reported.
