Venous island flap has many advantages over other flaps, such as random pattern flap, island flap or free flap. It can cover the defect with wide arc of rotation and does not require vessel anastomosis and arterial pedicle, hence more sites are available for donor. The procedure is a time saving and simple procedure and can be performed even by two operating members. But it is not frequently used because of the poor survival of the flap. In this study, we attempted to allow whether pharmacological or delay procedure can enhance the survival of the venous island flap and the mechanism of the delay flap survival. We devised a model of venous island flap whose pedicle was a branch of central vein on the auricle of Newzeland white rabbit. SOD, allopurinol and SOD and allopurinol were given as pharmacological treatment and delay procedure was carried out to enhance the survival of the flap. For the study of survival mechanism of the delay flap, SOD levels of the delay and non-delay flap were observed by SOD 525 method. The results were as follows: 1. Allopurinol, SOD and, SOD and allopurinol improved the survival of the flap significantly. 2. Delay procedure improved the survival of the flap significantly. 3. The level of SOD in delay flap was higher than that of non-delay flap regardless of the site within the flap or time passage. In conclusion, it is inferred that the administration of allopurinol and SOD and surgical delay can enhance the survival of the venous island flap. In delay venous island flap, increased level of SOD within the flap seem to contribute to the increased survival of the flap.

OBJECTIVE: The purpose of this study was to determine the reliability and usefulness of the lateral femoral cutaneous nerve conduction study by comparing the modified Ma's method (method I) with the method proposed by Spevak and Prevec (method II) and to develop a standard value of the Korean normal adult by the method II. METHOD: Twenty-nine healthy adults were examined for the lateral femoral cutaneous nerve conduction by both methods bilaterally. The nerve was stimulated 1 cm medial to anterior superior iliac spine (ASIS) in the method I and 8 cm distal to ASIS in the method II. The sensory nerve action potential was recorded with 8 cm long strip electrodes placed on the thigh 17 cm distal to ASIS in the method I and 33 cm distal to ASIS in the method II. RESULTS: 1) Among 58 extremities, a sensory nerve action potential was detected in 52 extremities (89.7%) by the method I and in 57 extremities (98.3%) by the method II without a significant difference between both methods. 2) The mean distal latency was 3.41 msec by the method I and 4.56 msec by the method II. 3) The mean amplitude was 7.24 microvolt by the method I and 6.63 microvolt by the method II without a significant difference between both methods. 4) The mean conduction velocity was 50.9 m/sec by the method I and 55.2 m/sec by the method II without a significant difference between both methods. CONCLUSION: According to the study, both methods are compatible and reliable for the examination of lateral femoral cutaneous nerve except for a significant difference in a mean conduction velocity.

Cystadenomas are benign neoplasm in which the epithelium demonstrates adenomatous proliferation. Several morphologic variants of cystadenomas have bean described, including papillary-oncocytic, mucous, and seromucous subtypes. Cystadenomas arising from salivary glands are very rare and seromucous cystadenoma of parotid gland has not been reported in Korea so far. Cystadenomas of the parotid gland usually Present as asymptomatic slowly growing mass and those of the minor salivary glands produce smooth nodules that may be compressible. We performed a superficial parotidectomy in a patient with a seromucous cystadenoma. This may be the first report of seromucous cystadenoma of carotid gland in Korea.

The possible complications after parotidectomy are facial nerve palsy, Frey's syndrome, sialocele, salivary fistula, hematoma infection, and flap necrosis. Postoperative sialocele and salivary fistula are relatively uncommon and the management varies. We experienced a rare postoperative complication of excessive and prolonged drainage of saliva after superficial parotidectomy and removal of an necessary parotid gland tumor. The patient could be treated successfully with conservative management such as compressive dressing, restriction of oral intake of irritant food, maintenance of oral hygiene and the use of amitriptyline(antidepressant).

PURPOSE: Algorithms to get cross-sectional bone density pattern(transverse histogram) to predict the loosening of hip prosthesis using DXA(Dual X-ray Absorptiometry) have been developed. We performed this study to analyze the correlation between radiologic findings and densitometric pattern of the THRA(Total Hip Replacement Arthroplasty) patients. MATERIALS AND METHODS: Thirty-six hips of 32 THRA patients were evaluated. The duration between THRA and DXA was from 1 year 7 months to 15 years. On transverse histogram, the periprosthetic bone density patterns were classified as 3 types;type I, rigid fixation in 17, type II, definite loosening in 8, and type III, partial loosening in 11 cases. Surgical findings, plain X-ray findnings and transverse histogram using DXA were correlated. RESULTS: Among 14 cases performing revision for acetabular prosthesis loosening, 5 cases revealed loosening of fernoral stems while 9 cases revealed rigid fixation of femoral stems. Sensitivity was 100% for either plain X-ray or DXA. Specificity was 88%, 77% for plain X-ray and DXA respectively. CONCLUSION: This preliminary study reveals that periprosthetic bone density pattern on transverse histogram on DXA may be useful in the evaluation of the loosening. However, further study will be needed for clinical application.

Menetrier's disease is a rare cause of thickened gastric wall. The differential diagnosis of diffuse gastricwall thickening such as lymphoma and adenocarcinoma should be expanded to include Menetrier's disease. The authorsexperienced a case of Menetrier's disease accompanied deep vein thrombosis, which was proved by operation andpathology. We carried out double cntrast upper G-I series and computed tomography , and report with review ofliteratures.
