Case ReportsCongenital hemidiaphragmatic agenesis presenting as reversible mesenteroaxial gastric volvulus and diaphragmatic hernia: a case report.
A 70-yr-old woman complained of left sided chest pain and non-bilious vomiting for four days after taking a gastric bloating agent for an upper gastrointestinal study. The chest radiography revealed gastric air-fluid levels and bowel loops in the left thoracic cavity. An emergency thoracotomy was performed. ⋯ We provided warm saline irrigation and performed a left lower lobe adhesiotomy. Thirteen days after surgery, the chest radiography showed improvement in the herniation but mild haziness remained at the left lower lung field. Here we present the oldest case of congenital diaphragmatic agenesis presenting with transient gastric volvulus and diaphragmatic hernia.

Case ReportsThe first case of antibiotic-associated colitis by Clostridium difficile PCR ribotype 027 in Korea.
Clostridium difficile (C. difficile) is a common causative agent of pseudomembranous colitis (PMC). C. difficile-associated diarrhea (CDAD) ranges from mild diarrhea to life threatening PMC. Recently, a highly virulent strain of C. difficile polymerase chain reaction ribotype 027 was found in North America, Europe, and Japan. ⋯ This is the first case of C. difficile PCR ribotype 027 in Korea. After discharge, she was maintained on probiotics and rifaximin for 3 weeks. She had no relapse for 6 months.

Advanced surface reconstruction technique to build detailed surface models of the liver and neighboring structures from the Visible Korean Human.
Unlike volume models, surface models, which are empty three-dimensional images, have small file size, so that they can be displayed, rotated, and modified in a real time. For the reason, the surface models of liver and neighboring structures can be effectively applied to virtual hepatic segmentectomy, virtual laparoscopic cholecystectomy, and so on. The purpose of this research is to present surface models of detailed structures inside and outside the liver, which promote medical simulation systems. ⋯ From the segmented images, serial outlines of each structure were stacked; on the popular commercial software, advanced surface reconstruction technique was applied to build surface model of the structure. A surface model of the liver was divided into eight models of hepatic segments according to distribution of the portal vein. The surface models will be distributed to encourage researchers to develop the various kinds of medical simulation of the abdomen.

The aim of current study was to evaluate the incidence and characteristics of ocular sarcoidosis in a Korean population. We conducted a retrospective study of 104 consecutive patients with biopsy-proven sarcoidosis seen at Asan Medical Center in Seoul, Korea, from 1993 to 2007. Medical records, photographs, and fluorescein angiograms were reviewed. ⋯ All ocular inflammation was well managed with topical steroid and/or systemic steroid with relatively good final visual outcomes. Ocular complications such as cataract (12 eyes, 30%), glaucoma (6 eyes, 15%), vitreous opacity (1 eye, 3%), cystoid macular edema (3 eyes, 7%), neovascularization (2 eye, 5%), and epiretinal membrane (4 eye, 10%) were related to ocular sarcoidosis. In Korea, where sarcoidosis is very rare, our study indicates relatively low ocular and predominantly non posterior segment involvement with relatively good visual prognosis.
