Frey's syndrome is a fairly common sequelae of surgery, trauma and inflammation of the parotid gland. Some patients with Frey's syndrome may be socially compromised by their gustatory sweating and flushing. In the past three decades, a variety of surgical and pharmacological methods have been unsuccessful in alleviating these symptoms. And since misdirection of auriculotemporal secretomotor nerve fibers has been found to play an important role in the development of the syndrome, a study was initiated to attempt mechnical interference with regenerating nerve fibers. Therefore, the recent trend in management of Frey's syndrome has been the use of prophylactic procedures performed at the time of parotidectomy to prevent its symptoms postoperatively. An additional benefit of this approach is prevention of the typical cheek contour deformity after parotidectomy We reviewed our experience with interposition of a vascularized temporoparietal fascial flap between the parotid bed and overlying skin immediately after complete superficial parotidectomies to prevent Frey's syndrome and hollow contour defects. The result of seven consecutive attempts revealed it to be an effective technique, achieving both goals in all patients with minimal morbidity.

PACS (Picture Archiving and Communications System) is a computer-based image storage and retrieval system that can store, recall and display medical images rapidly on high resolution workstations. The image acquisition system consists of direct digital interface to computed radiography (CR) system. We reviewed X-rays of 84 patients who had both studies of Dual energy X-ray Absorptiometry (DXA) and AP, lateral views of lumbar vertebrae between January and December of 1995. We tried to verify the clinical implication of pixel values on PACS for DXA by comparing pixel values and bone mineral density (BMD) of the 2nd, 3rd and 4th lumbar vertebrae. They were all female between 44 and 72 years old, average age of 59. Bone mineral density (BMD), represented in DXA of a total of 252 vertebrae were mostly in the range of between 0.228 (22%) and 1.318 (121%). Pixel values of the AP and lateral views of the 2nd, 3rd and 4th vertebrae in the PACS workstation were closely correlated to bone mineral density (p=0.0001). The values of the DXA (bone mineral density and T score) get comparatively lower as the pixel values get smaller. In conclusion, the pixel value on PACS interfaced to CR could be utilized as an easy, speedy and economical tool for screening of osteoporosis.

The blood bank of the Seoul National University Hospital has joined the U.K. National External Quality Assessment Scheme(NEQAS) for Blood Group Serology since 1992. We reported correct answers on all occasions for thirty-six samples tested for ABO, RhD typing, and direct antiglobulin test. Among 36 antibody screening and antibody,,identification tests, we missed one anti-S. Among 96 crossmatchings, we made 4 major errors and one minor error. It was interesting that all of the major errors we made were from the sample delivered in mid-summer. Since the items included in the domestic program for the external quality control of blood group serology are very limited in Korea, joining any international quality control program will be necessary for larger blood banks to assure quality of varirous blood bank tests being performed.
