BACKGROUND: Diabetes mellitus is a heterogeneous group of disorders characterized by high serum glucose levels and by disturbances of carbohydrate and lipid metabolism. There are many cutaneous signs of this common endocrinopathy, such as nercobiosis lipoidica diabeticorum, diabetic bullosis, shin spot, diabetic pruritus, etc. OBJECTIVE: In this study, we investigated whether extracellular matrix gene expression in cultured skin fibroblast is influenced by insulin and Insulin-like growth factor-I(IGF-I). METHOD: Total RNA was isolated from insulin or IGF-I treated human skin fibroblasts. The Northern blot and slot-blot hybridization were then conducted. RESULTS: The mRNA levels of pro α1(I) collagen, pro α1(I11) collagen, fibronectin in insulin and IGF-I treated normal skin fibroblasts increased compared with untreated normal skin fibroblasts. CONCLUSION: Our results show that insulin and IGF-I stimulate collagen formation in normal skin fibroblast at physiological concentrations. Therefore, these demonstrate that insulin can modulate the expression of extracellular matrix gene.

Cutaneous metastases from internal carcinornas are relatively rare. The frequency of metastases to the skin varies from 0.5-4.4%. We report a case of cutaneous metastasis suspected to originat from stomach cancer. A 44-year-old female, who had an episode of total gastrectony under diagnosis of stornach cancer three years ago, had multipe painless erythernatous nodules on the case and neck for one year. Histologic findings shows atypical anaplastic cell infiltration at the derr is and subcutaneous tissues. Cells with hyperchrornatic and erally displaced nuclei were recogniz d PAS staining shows positive reactions within the cells of glarid like structure. She died twelve month after the appearance of the cutaneous lesions.

Great strides has been made in the past 20 years in the treatment of scoliosis. Treatment before scoliosis becomes severe eliminates the need for extensive surgery. Early detection of scoliosis by school screening has proven to be valuable for early diagnosis and prevention of severe deformities. Authors screened 5,256 middle and high school students in Seoul, who were chosen arbitrarily, to determine the incidence rates of scoliosis, and following results were obtained. 1. Scoliosis was diagnosed on a combination of at least one positive physical sign and a lateral curvature more than 5 degrees on an antero-posterior standing X-ray. 2. The overall incidence of scoliosis was 4.68% (Male 0.74%, Female 6.43%). 3. Idiopathic scoliosis was found in 238 students, congenital scoliosis in 5, and paralytic scoliosis in 3. 4. The most common pattern of curvature was thoracic curve. 5. In the single curve right to left ratio was 2.1, but 8.4 in the upper curve of double curve. 6. Close observations were required for all the 246 students and treatment was required in 14 students who had more than 20 degrees, 9 students for Milwaukee brace, and 5 students for surgical correction.

Lupus vulgaris is most prevalent on exposed parts, especially the face but can also develop on exetremities. Lupus vulgaris originates from tuberculosis elsewhere in the body by hematogenous, lymphatic, or contiguous spread. A 19-year-old male patient came to our department. The patient had had many recurrent oozing and verrucous plaques and crusts on the left foot for one year. A skin biopsy from the lesion on the left dorsum of the foot showed scattered well defined granulomas consisting of the epithelioid cell clusters with Langerhans and foreign body type giant cells in the mid dermis. Caseation necrosis was slight. There were no bacilli on AFB staining. The multi test CMI for tuberculin was highly positive. A chest X-ray did not show any abnormal findings. The presence of Mycobacterium tuberculosis DNA was demonstrated by polymerase chain reactions (PCR) for detection of mycobacterial DNA from a routinely prepared paraffin-embedded skin specimen. Herein we report a very atypical case of lupus vulgaris confirmed by PCR.

BACKGROUND: A clinical study of rosacea has never been reported in Korea. OBJECTIVE: The purpose of this study was to elucidate the clinical observations of rosncea. METHODS: During a 5-year-period from Jan. 1990 to Dec. 1994, 133 patients were evaluated with regard to age, sex, location of skin lesions, clinical type, duration, and precipitating factors. RESULTS AND CONCLUSIONS: 1. Of the 7,787 cases amongst outpatients, 133 cases(1.7% ) were dignosed with rosacea. Of there 46 were male patients and 87 females, giving a sex ratio of 1:1.9 in favor of females. 2. The most common type of rosacea was vascular rosacea(60.2%) 3. The average duration of rosacea was 3.4 years. 4. Rosacea afflict persons aged 40-49 most frequently. 5. The predilection sites of the rosacea were : cheek(42.9%), nose(23.3%), entire face(11.3%), cheek & nose(9%), zygomatic area(6.8%), extra-facial area(3.8%), forehead(2.9%). 6, The aggravating factors of rosacea were : unknown cause(32.3%), coffee & tea(18%), alcohol(13.5%), emotional stress(10.5%), sun exposure(9.8%), multi-factoral(7.5%), drugs(steroids)4.6%).
