BACKGROUND: It has become generally accepted that cigarette smoking contributes to accelerated coronary and peripheral vascular disease, pulmonary fibrosis and periodontal disease. Moreover, it has been postulated that cigarette smoking causes skin-aging. Many of cutaneous manifestations of nicotine which is a major component of the particulate phase of tobacco smoke are related to its vasoconstrictive and thrombotic effects on the peripheral vascular system. How-ever, direct effect of nicotine on extracellular matrix (ECM) proteins including collagens is not well established. OBJECTIVE: To evaluate the effect of nicotine on type I collagen gene expression in cultured human skin fibroblasts. METHODS: After exposure to different doses of nicotine on cultured human skin fibroblasts, we examined the expressions of α1(I) procollagen gene and fibronectin gene by Northern blot analysis and chloramphenicol acetyltransferase (CAT) assay with CAT construct containing the 3.5 kb COL1A2 promoter. RESULTS: In Northern blot hybridization, steady-state levels of α1(I) procollagen mRNA were decreased 0.8-fold at 1 µg/mL of nicotine, 0.5-fold at 10 µg/mL and 0.2-fold at 100 µg/mL, compared to untreated control. Those of fibronectin mRNA were decreased 0.9-fold, 0.7-fold, and 0.3-fold, respectively. In CAT assay, the relative COL1A2 CAT activity was 1.0 in the untreated control, 0.7 at a concentration of 1 µg/mL of nicotine, 0.5 at 10 µg/mL, and 0.3 at 100 µg/mL. CONCLUSION: These results indicate that nicotine is a down-regulator of collagen gene expression at transcriptional level in vitro. We speculate that nicotine may contribute to the skin-aging by modulation of extracellular matrix gene expression including collagen as well as by its vasoconstrictive and thrombotic effects.

BACKGROUND: Psoriasis is the most prevalent T-cell-mediated inflammatory skin disease in humans. Numerous cytokines and adhesion molecules are expressed in the skin lesion of psoriasis such as TNF-α, IL-1, IL-6, VCAM-1 and ICAM-1. All of them contain at least one binding site for the transcription factor NF-κB. TNF-α activates NF-κB and many other transcription factors. Thus, transcription and expression of many genes involved in the inflammatory process may be influenced by TNF-α. OBJECTIVE: The purpose of this study was to study the effect of synthetic double-stranded DNA with high affinity for the NF-κB binding site on the TNF-α induced proinflammatory cytokines and ICAM-1 gene expression in the HaCaT cells. MATERIAL AND METHODS: We examined whether inhibition of NF-κB activity by oligodeoxynucleotides (ODN) decoy for NF-κB blocks TNF-α induced cytokines such as IL-la, IL-1 a, IL-6 and ICAM-1 expression with electrophoretic mobility shift assay (EMSA) and reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: In EMSA, TNF-α treatment (10 ng/ml) induced the activation of NF-κB. The NF-κB binding activity in the TNF-α treated HaCaT cells increased 5.0-fold compared to non-treated group. Next, we examined the effect of liposome mediated NF-κB decoy oligonucleotides (ODN) transfection. After transfection of the NF-κB decoy ODN, TNF-α increased NF-κB binding activity to 1.9-fold of non-treated group. Accordingly the transfection of NF-κB decoy ODN inhibited the TNF-α induced NF-κB binding activity up to 63%. RT-PCR analysis revealed that the transfection of NF-κB decoy ODN inhibited TNF-α induced cytokines and ICAM-1 mRNA expression. CONCLUSION: Taken together, our results suggest the potential utility of NF-κB decoy technique for biologic therapy of psoriasis.

Primary hyperparathyroidism is a rare endocrine disease in children. It involves bone and joint, urinary tract, gastrointestinal tract and cardiovascular system. The main cause of these involvement is high level of PTH in serum, resulting in hypercalcemia.An 11 years old male patient who had complained of limping gait since last 18 months, showed typical laboratory and radiological findings of primary hyperparathyroidism. At the ultrasonography, computed tomography and radionuclide scanning, a well defined mass(10 X 15mm) was found on the posterior aspect of the right thyroid lobe. The mass was confirmed histologically as adenoma of parathyroid gland. The patient was successfully treated with subtotal parathyroidectomy and temporal administration of calcium and vitamin D.We report this case of primary hyperparathyroidism with brief review of the literatures.

BACKGROUND : A discussion of the chronologic trends of operative indications of breast masses for proper management of breast masses is desirable. METHODS : A retrospective analysis of 882 patients with breast masses who underwent operations at Kangnam General Hospital from January 1986 to December 1997 was done. All the lesions were classified according to for age, size of the mass, and the pathologic result. Concurrently, the distributions of the different masses were retrospectively analyzed for each one-year time period. RESULTS : The most prevalent age group was the third decade (28.6%) followed by the fourth decade (25.3%) and the fifth decade (24.4%). The most common lesion was fibroadenoma (38.7%), followed by mammary dysplasia (22.6%) and malignancy (18.3%). In fibroadenoma, the most common pathologic type was intracanalicular (34.9%), and the juvenile type occurred in significantly younger patients compared to other types (19.2 vs 29.2 years of age). In mammary dysplasia, the most common pathologic type was fibrous (74.4%), and the epithelial hyperplasia and adenosis types were occurred in older patients compared to the other types (39.1 and 41.0 vs 33.5 and 35.4 years of age). As the chronologically changing pattern of the pathologic types, the number of mammary dysplasia had a decreasing tendency and fibroadenoma had a relatively increasing one, and the reason may be the effect of fine-needle aspiration cytology. CONCLUSIONS : The result of this study shows that the distribution of the disease in terms of age and frequency is almost the same as that of other reported results. The trend of the disease types in terms of the time period shows that the operation rate for fibroadenomas is increasing while the rate for mammary dysplasia is decreasing. This tendency might come from the decreasing use of surgical biopsy for mammary dysplasia.

Metastasis to the skin from internal malignant neoplasms are an uncommon and often preterminal event. Although carcinoma of the cervix is the fourth most common malignancy in women, cutaneous involvement originating from cervical cancer is particularly unusual, even in the terminal stages of disease. We report two cases of cutaneous metastasis from cervical cancer. Case one was a 57-year-old woman, who has been treated with radiotherapy and chemotherapy for an cervical cancer(Stage IIa) since 11 years ago. She showed multiple grouped shallow ulcerative nodules and papules on the external genitalia 1 month ago. Another case was a 46-year-old woman noted irregular vaginal bleeding, and pelvic examination revealed an cervical cancer(Stage IIb) for 2 years ago. She visited our clinic because of swelling of the right leg and multiple erythematous nodules and ulcerative lesion on the right thigh for 2months. Histopathologic findings showed skin tumors, which were considered to originate from the cervix.
