BACKGROUND: Ultraviolet B(UVB) light, which can cause severe damage like induction and promotion of cancer, cutaneous inflammation and immunosuppression, represents one of the most important environmental impacts for humans. Keratinocytes are natural target cells of UVB in humans. NF-kB plays a role in the cell of the immune system, where it controls the expression of various cytokines and the major histocompatibility complex gene. OBJECTIVE: The purpose of this study was to examine the effect of UVB on the NF-kB and AP-1 activity in cultured human keratinocytes and fibroblasts. METHODS: Keratinocyte and fibroblast cultures were produced with DMEM medium. Cells were irradiated for 100J/m, 200J/m, 300 J/m. and Nuclear proteins were extracted. AP-1 and NF-kB activities were measured by the gel shift mobility assay. RESULTS: Gel shift mobility assay. 1. The NFkB activity was increased upon UVB in a dose dependent manner in the keratinocyte. 2. Enhanced levels of AP-1 binding activity in the radiated extracts frorn human skin keratinocytes were detected. 3. The levels of GRE (glucocorticoid responsive element) binding activity were similar in both radiated and unradiated extracts from fibroblasts and keratinocytes. CONCLUSIONS: The activities of NF-aB and AP-1 are increased following stimulation of a cell with UVB irradiation. Therefore, UV induced skin tumors, abnormal cell proliferation, cutaneous inflammation and immunosuppression, may be due to these transcriptional factors.

Iatrogenic Cushings syndrome is caused by administration of systemic steroids for some disorders, and is clinically characterized by truncal obesity, hypertension, fatigability, amenorrhea, hirsutism, abdominal striae, edema, glucosuria and osteoporosis. We report herein a case of iatrogenic Cushings syndrome in the treatment of atopic dermatitis. The patient, a 32-year-old male, had been diagnosed with atopic dermatitis and was intermittently treated with topical and systemic steroids for 12 years. He revealed facial edema, truncal obesity and striae distensae in both the axilla and abdomen. Steroids are one of the important agents in the treatment of atopic dermatitis but care must be taken in their administration.

We observed a 55-year-old man who had granuloma pyogenicum on the medial border of the right fifth toe which developed after scratching of the wound. Histopathological findings showed many newly formed capillaries that had prominant endothelial cells and showed varying degrees of dilation without appearance of epidermal collarette signs. We tried intralesional treatment with triamcinolone acetonide (10mg%, 1/week*3). After 3 sessions of treatment, the lesion dramatically regressed nearly to normal size.

OBJECTIVE: To evaluate the clinicopathologic features and clinical outcomes of adnexal tumors in pregnancy. METHODS: After review of charts of 51 patients managed at Kyungpook National University Hospital from January 1996 to June 2002, data including clinical findings, treatments and outcomes were analyzed. RESULTS: The mean age of pregnant women with adnexal tumors was 28.5 years old and the adnexal tumors were more common in nulliparous pregnant women (74.5%) than parous those. There were asymptomatic or no signs in 40 cases (78.4%), lower abdominal pain in 9 cases (17.6%), vaginal bleeding in 1 case (2.0%) and palpable mass by patient herself in 1 case (2.0%). The surgical treatments were performed at first trimester in 9 cases (19.1%), second trimester in 31 cases (66.0%) and third trimester in 7 cases (14.9%). Postoperative histopathologic diagnoses of adnexal tumors were 22 cases (43.1%) of benign cystic teratoma, 7 cases (13.8%) of functional cyst, 6 cases (11.8%) of serous cystadenoma, 4 cases (7.8%) of mucinous cystadenoma, 4 cases (7.8%) of endometrioma, 3 cases (5.9%) of parovarian cyst and 4 cases (7.8%) of malignancy including 2 cases of mucinous cystadenocarcinoma and 2 cases of mucinous tumor, borderline. The complication resulting from adnexal tumors was torsion of 6 cases (11.8%). The outcome of pregnancy was available in 30 cases, term delivery in 25 cases (83.3%), preterm delivery in 3 cases (10%) and spontaneous abortion in 2 cases (6.7%). CONCLUSION: Although the incidence of adnexal tumors with pregnancy is variable according to the reports, the detection rate is more and more increasing due to a widespread application of ultrasound. Thus, obstetricians must always consider adnexal tumors combined with pregnancy and try to minimize the complications of surgery during pregnancy to prevent adverse fetal outcome and maternal morbidity.

10.Anesthetic Management of a Patient with Abdominal Compartment Syndrome : A case report.
Korean Journal of Anesthesiology 2007;52(1):111-114
Abdominal compartment syndrome (ACS) is a life-threatening emergency requiring prompt treatment. In these cases, a patient cannot ventilate effectively and oliguria can occur because of the high intra-abdominal pressure (IAP). The mortality rate is very high. Treatment is abdominal decompression and secondary closure. There are very few reports of the anesthetic management of a patient with ACS. We report a 38-year-old male patient who was diagnosed with ACS at the operating room. The IAP was measured and emergency abdominal decompression and "Bogota bag" apply were performed. The respiratory and hemodynamic parameters improved after this treatment.
