2.Expression of Basement Membrane Gene in Cultured Skin Fibroblasts from Patients with Diabetes Mellitus.
Annals of Dermatology 1996;8(1):1-5
BACKGROUND: Bullous eruption of diabetes(BD) is a rare cutaneous sign of diabetes mellitus(DM). The mechanism for the development of these lesions is unknown, although speculation has ranged from trauma to vascular insufficiency. OBJECTIVE: Our purpose is to evaluate the difference of basement membrane gene expression in cultured skin fibroblasts between patients with diabetes and normal controls. METHODS: Total RNA was extracted from cultured skin fibroblasts of DM and normal, and then Northern blot and slot-blot hybridizations were done. RESULTS: The mRNA levels of a(I) procollagen, a(IV) procollagen, fibronectin, and laminin B1 were not altered significantly in the DM. CONCLUSION: Our results suggest that BD has no relevance to the alteration of basement membrane components. Further studies are needed to clarify the underlying pathogenic mechanism of BD.

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: The clinical and histopathological classification of erythema multiforme(EM) and Stevens-Johnson syndrome (SJS) are difficult due to a lack of clear-cut criteria. In recent studies, some authors suggested that erythema multiforme and Stevens-Johnson syndrome were clinically and histopathologically different disorders. OBJECTIVE: The purpose of this study was to review the clinicopathological characteristics of the EM and SJS and to suggest specific findings for differentiating between the two diseases. METHODS: Fifty four patients with EM and SJS diagnosed in the Department of Dermatology of Dong-San Hcepita1 from January 1987 through to December 1996 were studied retrospectively. RESULTS: The results were summarized as follows. l. In view of causal factors, 54 cases were classified as drug-induced (n=22, 41%), herpes-induced (n=16, 30%), tuberculosis (n= 2, 3%), pneumonia (n=l, 2%), unknown (n=13, 24%). 2. Fifty four cases were clinically classified as SJS (n= 29, 54%), EM minor (n=-15, 2S%) and EM major (n = 10, 18%). 3. Erythema multiforme was found to be more related to herpes (13 of 25 cases) than to drugs (3 of 25 cases), while SJS was more related to drugs (19 of 29 cases) than to herpes (3 of 29 cases). 4. Varying degrees of necroti changes of keratinocytes were found in all the cases. The severity of degree or extent of necrosis was higher in patients with SJS than EM. 5. In demial changes, EM showed differences from SJS by having a denser and deeper lymphocytic infiltrate, and increased amount of extravasated erythrocytes. CONCLUSION: Taken together, although our findings could not provide a defmite clue to determine whether EM and SJS are different distinet entities or not, this study may be useful to differentiate and to understand the pathogenesis of EM and SJS. A prospective large scaled study should be conducted to definitively characterize these entities.

BACKGROUND: Sun exposure and therapeutic irradiation have been shown to induce alterations in extracellular matrix (ECM) proteins, including elastin, glycosaminoglycan and collagens. The integrity of the connective tissue mainly depends on balanced rates of matrix synthesis and degradation of the extracellular matrix. Therefore, matrix metalloproteinases (MMPs) may be involved in ultraviolet irradiation (UVR)-induced alterations in ECM proteins. OBJECTIVE: To evaluate the effects of UVA as well as UVB irradiations on ST-1 gene expression in cultured human skin fibroblasts. METHODS: After exposure of different doses of UVA and UVB on cultured human skin fibroblasts, we examined the expression of ST-1 gene by Northern blot analysis, chloramphenicol acetyltransferase (CAT) assay with CAT construct containing AP-1 binding site. Additionally, we carried out the gel mobility shift assay to investigate the effects of UVR on the DNA-binding activity of AP-1. RESULTS: After UVR on fibroblasts, the steady-state levels of ST-1 mRNA were in-creased in response to UVA and UVB by 2.5-fold and 4.2-fold, respectively, as compared with controls. Similar results were obtained by CAT assay showing that CAT activity increased as the UVA and UVB doses increased. Furthermore, gel mobility shift assay demonstrated that both UVA and UVB increased AP-1 DNA binding complexes. CONCLUSION: UVB as well as UVA up-regulated ST-1 gene expression at transcriptional levels in vitro. We speculate that modulation of MMPs, including ST-1, gene expression by UVR may contribute to the connective tissue damage related to photoaging and other photocutaneous disorders.

We herein report a case of therapy-resistant dermatomyositis treated with oral prednisolone and chlorambucil combination therapy. Concurrently, she showed cervical carcinoma in situ(CIS). Initially, we started to treat her with combination oral prednisolone, intramuscular methotrexate, hydroxychloroquin, and removal of cervical CIS. However, our patient failed to respond to these regimens. Thus, we had have another combination treatment of oral prednisolone and chlorambucil. After the treatment of this combination regimen, her recalcitrant dermatomyositis improved dramatically without recurrence. There were no significant adverse side effects with chlorambucil therapy.

Cutaneous polyarteritis nodosa(CPAN) is a benign form of rare vasculitis of small and medium-size arteries with a recurrent but benign course without systemic involvement. We experienced a 61-year-old male who had two months history of multiple deep-purpurish livedo reticularis on both lower legs. Noncutaneous manifestations including malaise, fever, myalgia, and arthritis were absent. A skin biopsy specimen from the livedo reticularis on the leg showed perivascular and trans-mural neutrophilic and lymphocytic infiltration of medium-sized arteries in the dermal-subcutaneous junction and fibrinoid necrosis of the vessel walls. The patient was treated with colchicine for 2months and showed markded improvement.

We present a case of lymphangioma circumscriptum in a 17 year-old girl according to tihe clinical and histopathological findings. This case is unusual in that lesions developed on the vulva and thigh without preceding lymphedema. Our patient had a plaque of grouped vesicle-like papules resembling frog's apawn on The both labia majora of vulva and several scattered, skin tag like soft papules on the right upper thigh of theree years duration. Histopathologic findings showed variable sized, dilatated lymphatic channels lined by single layer of normal endothelial cells confined to the only upper dermis.

Slipped femoral capital epiphysis is a rare entity in Korea and only three cases have been reported so far1,2,3). One of our cases was a unilateral mild chronic slip in a 14 year old boy with Frohlich body type. It was treated by gentle closed reduction followed by knowles' pin fixation. The other case, a 20 year old female, presented chondrolysis of the left hip. Scrutinization of roentgenograms revealed typical features of an unrecognized slipped femoral capital epiphysis. It was treated by Wagner resurfacing replacement arthroplasty.

10.Leg Length Equalization by Correction of Pelvic Obliquity and Acetabular Dysplasia

The Journal of the Korean Orthopaedic Association 1982;17(6):1137-1148
Fixed pelvic obliquity refers to a composite deformity induced by contractures both above and below the pelvis and the elements of this deformity are frequently interrelated during the period of growth. From the functional standpoint, leg length discrepancy is caused by deformities of the pelvis and lower extremities, such as pelvic obliquity and acetabular dysplasia, as well as by inequality of true limb bone length, and these deformities either aggravate or compensate functional discrepancy. During fhe fourteen years period, from August 1968 to August 1982, at the Department of Orthopaedic Surgery, Seoul National University Hospital, we treated 35 cases of fixed pelvic obliquity and acetabular dysplasia associated with true or functional limb length discrepancy by means of lumbodorsal fasciotomy or pelvic osteotomies such as Salters innominate osteotomy or Steels triple osteotomy, combined, if necessary, with contralateral abductor fasciotomy to gain functional limb length as well as to improve posture and balance. In many cases of residual poliomyelitis, epiphysiodesis was also performed when indicated. These cases were reviewed and following observations were made: 1. Of the 35 cases, residual poliomyelitis with 29 cases (83%) was by far the main cause of leg length discrepancy. Cerebral palsy (2cases), Legg-Perthes disease (2 cases), and fibrous ankylosis secondary to septic hip (2 cases) comprised the remainder. 2. The male-to-female ratio was about equal, being 17 to 18. 3. The average age at the time of operation was 17.9 years, the youngest being 7 years and the oldest being 30 years. The average age at the time of current follow-up was 18.8 years. 67% of those followed was skeletally mature. 4. An average of 1.35cm of bone length was gained radiographically by pelvic osteotomies. Steels triple osteotomy was more effective in gain than Salters innominate osteotomy. 5. An average of 2.43cm of functional length when standing was gained radiographically by lumbodorsal fasciotomy alone. 6. An average of 2.61cm of functional length when standing was gained radiographically by lumbodorsal fasciotomy and combined contralateral Soutters or Campbells fasciotomy. 7. An average of 3.57cm of functional length when standing was gained radiographically by lumbodorsal fasciotomy and combined ipsilateral Steel's triple osteotomy. 8. An average of 1.73cm of functional lengthening when standing was corrected radiographically by ipsilateral Soutter's fasciotomy. 9. When lumbodorsal fasciotomy and Steel's triple osteotomy were combined with contralateral Soutter's or Campbell's fasciotomy, the average radiographic gain in standing length was 3.77cm. 10. Leg length discrepancy in terms of true bone length is conventionally corrected either by epiphysiodesis or bone shortening on the longer limb, or by bone lengthening on the shorter limb. We believe that when leg length discrepancy is associated with fixed pelvic obliquity, frequently aggravating the disability functionally, lumbodorsal fasciotomy and/or pelvic osteotomies on the shorter side and, combined if necessary, Soutters or Campbells fasciotomy on the longer side, can, in many instances, successfully correct or reduce functional limb discrepancy and improve balance, posture and function. Any residual discrepancy, true or functional, may then be corrected by conventional methods.
