Gallbladder Perforation Into the Peritoneal Cavity.

ABSTRACT: Gallbladder perforation is an uncommon but morbid complication of acute cholecystitis with mural ischemia and necrosis. The most common site of perforation is the fundus because of limited blood supply in this region. The Niemeier classification proposed in 1934 remains the criterion standard in grading gallbladder perforation; type 1 is acute with free perforation into the peritoneal cavity, type 2 is subacute with pericholecystic abscess, and type 3 is chronic with cholecystoenteric fistula. We report a challenging case of type 1 gallbladder perforation due to acute acalculous cholecystitis.

Quantitative Monitoring Wound Healing Status Through Three-dimensional Imaging on Mobile Platforms.

There are approximately 6.5 million patients in the U.S. suffering from chronic wounds and approximately 140,000 patients hospitalized every year with new wounds. With a long healing process, this demands the need for a non-contact, low cost, and remote monitoring solution that can assist clinicians in diagnosing and treating a patient's wound. This will reduce the burden of countless office visits, especially for those who are elderly and incapacitated. We present a mobile platform based wound 3D imaging app. The app is the only integrated measurement solution encompassing wound area and volume through low cost yet accurate 3D imaging. Extensive experiments show the app has 1.14% and 4.41% relative errors for wound area and volume measurement respectively, far exceeding currently employed clinic methods. In addition, non-invasive volume measurement methods currently use expensive industrial 3D (>$20K) cameras, but our solution provides cheap and accurate results.
