Korean Journal of Dermatology 1999;37(3):352-357
BACKGROUND: Various topical antisepties are often used for postoperative care of surgical wounds. But the effect of these agent on wound healing remains an area of debate. OBJECTIVE: The purpose of this study was to evaluate the biological effects of hydrogen peroxide on human keratinocytes in vitro, specifically on keratinocyte viability, migration and proliferation. METHODS: To evaluate the effects of hydrogen peroxide on keratinocyte viability, migration and proliferation, sulforhodamine B test, migration assay, and thymidine incorporation assay were performed, respectively. Diluted solutions of 30% hydrogen peroxide( X 50, X 100, X 500, X 1000) were used as testing material and growth medium alone as a control.

BACKGROUND: Laparoscopic cholecystectomy has become the standard treatment of benign gallbladder disease. It requires the skill of a trained surgeon, and its safe performance. The advantages of laparoscopy are less postoperative pain, absence of cosmetic damage, shorter recovery times, and decreased length of hospital stays compared with conventional open surgery. METHODS: We reviewed 500 consecutive laparoscopic cholecystectomies retrospectively at the department of general surgery of Maryknoll Hospital from February 1992 to May 1999. RESULTS: There were 175 males and 325 females(M:F=1:1.86) with ages ranged from 21 to 78 years (mean: 50.0 year). Preoperatively, 72 patients underwent endoscopic retrograde cholagiography and 7 patients underwent endoscopic sphincterotomy due to common bile duct stone. Mean operation time was 73.7 minutes. Operative cholangiogram was attempted in 8 patients. Conversion to open cholecystectomy during operation was done in 8 cases(1.6%) and leading causes were severe adhesion, uncontrolled bleeding, suspected malignancy, bile duct injury. Operative Complications occured in 18 patients(3.6%): bile duct injury 1, postoperative bleeding 1, bile leakage 4,subcutaneous emphysema 1, abdominal wall hematoma 3, wound infection 8. There was no operative mortality. The length of hospital stay ranged from 2 to 15 day with average of 4.7 day. CONCLUSION: Laparoscopic cholecystectomy is a safe and effective operation in patients with benign gallbladder diseases.

Neurofibrosarcoma is the most common malignant change in patients with neurofibromatosis. But the incidence of neurofibrosarcoma arising from cutaneous neurofibroma is very low. We report two cases of neurofibrosarcoma arising from cutaneous neurofibroma in patients with neurofibromatosis showing typical clinical manifestations.

The surgical technique of renal transplantation has been well established, but surgical complications are not uncommon and still be important factors in postoperative mortality and morbidity. From August 1990 to May 1998, we performed 250 consecutive renal transplantations at Maryknoll hospital. The authors analyzed the kinds and incidences of surgical complications in a single center by using information from hospital records. The results were as follows: 1. The overall surgical complication rate was 9.6% (24 episodes in 250 cases). 2. These were composed of 6 vascular, 8 urologic, 4 lymphatic, and 6 wound complications. 3. Vascular complication included renal artery stenosis in 1 case and bleeding and hematoma in 5 cases. 4. Urologic complication included urine leakage in 4 cases, ureter stenosis in 2 cases and bladder stone in 2 cases. 5. Lymphatic complication was all lymphoceles. 6. One case in which renal artery stenosis had occured progressed to graft loss after 4 years later. There was no complication related mortality. 7. 1 year, 3 year and 5 year graft survival rate was 97.2%, 94.8% and 90.0%, respectively. and patient survival rate was 98.0%, 95.6% and 94.7%, respectively.

We present a patient who developed granuloma in a previous herpes zoster scar (post-zoster granuloma). The development of granuloma in healed herpes zoster lesions may represent an atypical delayed hypersensitivity reaction to viral antigens or tissue antigens altered by the virus. To our knowledge, this is the first case reported in Korean literature.
