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.

BACKGROUND: Arthroscopic fixations for large and comminuted bony Bankart lesions are technically difficult. We developed an arthroscopic multiple pulled suture (MPS) technique to restore large and comminuted bony Bankart lesions. METHODS: Ten patients (mean age, 49.8 years; range, 31–79 years) underwent bony Bankart repair using the illustrated MPS technique and were then followed for a mean of 27.3 months. A plain radiograph series and three-dimensional computed tomography scans were taken at the initial clinical evaluation and 3 months postoperatively. Outcome measurements included the American Shoulder and Elbow Surgeons (ASES) score, Rowe score, University of California at Los Angeles (UCLA) score, and subjective patient satisfaction, along with surgical complications. RESULTS: Union of an osseous fragment with the glenoid rim was confirmed in all patients on a computed tomography scan 3 months after operation. The osseous fragment was restored to proper articular congruence and reduction. The affected shoulder was stable in nine of the 10 patients. One patient presented with a redislocation after a sports injury 3 years postoperatively. The ASES, Rowe, and UCLA scores improved at the final evaluation, and median patient satisfaction at the final follow-up was 9 of 10 points (range, 6–10 points). CONCLUSIONS: The arthroscopic MPS technique for bony Bankart lesions with large or comminuted osseous fragments was a relatively easy and safe method for stable fixation of the osseous fragment. Therefore, the arthroscopic MPS technique resulted in good restoration of stability with high patient satisfaction and low complication rates.

The purpose of this study is to evaluate the changes of central corneal thickness and axial length after laser-assisted in situ keratomileusis (LASIK) surgery for myopia. 101 eyes of 53 patients who underwent laser in-situ keratomileusis (LASIK) were included in this study.Routine examinations were done in all cases. Central corneal thickness, axial length, keratometry, and refractive error were measured preoperatively and on the 6 month post-operatively. Mean preoperative spherical equivalent was -5.52 D (SD, 1.98 D).Preoperative and postoperative mean central corneal thickness was 530.64 micrometer (SD, 27.62 micrometer)and 468.84 micrometer (SD, 33.32 micrometer).Preoperative and postoperative keratometry was 43.69 D (SD, 1.90 D)and 39.12 D (SD, 1.98 D).Preoperative and postoperative average axial length was 25.56 mm (SD, 1.05 mm)and 25.51 mm (SD, 1.08 mm).When postoperative measurements were compared with preoperative measurements, there was a significant decrease in central corneal thickness (t=25.68, p=0.000)and keratometry (t=23.61, p=0.000), but there was no significant difference in axial length (t=1.82, p=0.072). Refractive changes related to axial length measurements changes on the 6 month after LASIK are not important compared with the total refractive corrections of LASIK.

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%).

Ecthyma Gangrenosum is a rapidly progressing skin infection charact,erized by edema, hemorragic bullae and necrosis. Ecthyma Gangrenosum occurs almost exclusively in severely imrnunocompromised patients during the course of pseudomanas aeruginosa septisemia. A 5 month-old boy was transferred to our department because of multiple well defined central necrotic black-colored large erythematous bullae. In the bacterial cultures of skin, stool and liver aspiration fluid, Pseudomonas aeruginosa was grown. In the abdominal ultrasonogram and computed tomogram, the multiple liver abscess, hepatomegaly and ascites were shown on both hepatic lobes. Herein we report a case of ecthyma gangrenosum associated with liver abscess.

PURPOSE: To report a previously unreported secondary Mooren's ulcer associated with simultaneous sur-gery for cataract and pterygium. METHODS: Case report. Five days after simultaneous surgery for cataract and pterygium, an 86-year-old woman developed severe pain and a superior and inferior peripheral corneal ulcer that had the characteristic clinical appearance of Mooren's ulcer. RESULTS: Peripheral corneal ulcer is rapidly progressive, painful, beginning at the limbus with a gray, overhanging, infiltrated edge at its central border. She had no history of collagen-vascular disease, negative serologic test result, and negative culture for pathogen. Surgical trauma may have been the inciting factor in development of the ulcer. She was treated with topical and systemic steroids. After complete control of the inflammation, the patient remained in remission.

The nevus sebaceus of Jadsssohn is an organoid nevus generally noted on the scalp or the face as a single lesion. A 26-year-old man has suffered from a pea sized, pedunculated cherry red colored papule on the back ground of yellowish colored verrucous plaque on the vertex. Clinically, pedunculated papule was similar to granuloma pyogenicum, but histopathologic examination showed the features of tubular apocrine adenoma with focal areas of syringocystadenoma papilliferum, suggesting that might be a variant or could be associated with syringocystadenoma papilliferum.

The purpose of this study is to compare, by statistical analysis, intraocular lens (IOL) powers by SRK/T formula using autorefractokeratometer-measured keratometric (K) values (SRK/T-ARK-mK), by SRK/T formula using refraction-derived K values (SRK/T-R-dK), and by refraction corrected method (RCM), in eyes treated with photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) for myopia. Thirty-eight consecutive eyes of 23 patients with PRK for mild to moderate myopia and 35 consecutive eyes of 25 patients with LASIK for high myopia were followed up for more than 1 year. In the two groups, IOL powers by SRK/T-ARK-mK, by SRK/T-R-dK, and by RCM were compared by statistical analysis. In PRK group, the mean value of IOL powers by RCM was statistically higher than that obtained by the other two methods (p < 0.05), while there was no significant statistical difference between the mean values of IOL powers by SRK/T-ARK-mK and by SRK/T-R-dK (p > 0.05). However, in LASIK group, the mean values of IOL powers by RCM and by SRK/T-R-dK, which did not differ statistically (p > 0.05), were both statistically higher than that by SRK/T-ARK-mK (p < 0.05). In conclusion, there is a statistical difference in IOL powers by the methods used for IOL calculation, as there is according to the level of myopia in patients with PRK and LASIK treatment. We suggest that, in IOL power calculation in eyes with previous corneal refractive surgery, correction methods such as RCM and SRK/T-R-dK are more effective at higher levels of myopia.
