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.

Giant basal cell carcinoma(BCC) is a clinical expression of a large-sized BCC, which can cause extensive local invasion and disfigurement and have a particular capacity for metastasis. In the development of this large tumor, several risk factors including patient neglect, aggressive histological features and long duration, are identified. We have observed a very large BCC on the forehead of anlderly man for more than 4 years. He had been suffering from psychiatric disease for a long time, and patient neglect due to this problem played a crucial role in the development of this giant BCC.

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.

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.

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.
