The author observed one case of typical Linear bassal cell nevus who was 3 year old girl. Since birth, skin lesions reveal a linear band like nodules along the left lateral margin of nose, which are consists of pinhead sized, normal skin colored, pearly and translucent papules. Histopathologically, the preparations showed muItifocal irregular masses of basal type epithelial cells in continuity at pilosebaceous follicles and the cells were oval or spindle shaped and a peripheral palisade arrangement. But comedones and nevus cells were not identified. Diagnosis confirmed by clinical appearance, histopathologically and other clinical study. There were marked improvement by the locaI application of 2% 5-Fluorouracil solution.

OBJECTIVES: Anticardiolipin antibody (ACA) and lupus anticoagulant (LA) are acquired antiphospholipid antibodies (APAs), which are regarded as important risk factors far vascular thrombosis and recurrent fetal loss. Although the clinical relevance of APAs in dialysis patients is uncertain, recent studies have suggested that APAs are involved in bioincompatibility and thrombogenic complications in hemadialysis (HD) patients. METHOD: We performed a cross sectional study of ACA and LA in 50 stable HD patients and their 68 vascular accesses (52 native arteriovenous fistulae and 16 synthetic arterovenous grafts), with the analysis of factors associated with the presence of APAs and the retrospective evaluation of vascular access occlusion (VAO). LA was assessed by platelet neutralization method whereas IgG-ACA was measured by a solid phase ELISA. Values higher than 23GPLU/ml (IgG phospholipid units) were considered to be positive for IgG-ACA and positive values for LA was more than 8 seconds in prolongation of the clotting time with human platelet lysate. Vascular access survival was assessed by Kaplan- Meier method, RESULTS: The mean age of the subject (M:F 21:29) was 46 years and the mean duration of hemodialysis was 49 months. The frequency of VAO in entire subjects was 0.45+/-0.98 episodes/patient year. The median value of IgG-ACA was 16.0 GPLU/ml with a distribution from 2.7 to 46.1GPLU/ ml. The median titer of I.A was 4.5 (3.1-45.6) seconds. Fourteen patients (28%) were found to have at least one episode of VAO. In spite of comparable clinical and biochemical data according to the presence of VAO, the titers of IgG-ACA (13.6+/-7.7 vs, 20.3+/-8.7GPLIJ/ml, P<0.05) and LA (4.5+/-2.9 vs. 11.7 +/-12.6sec, P<0.05) were significantly higher in VAO group. Six out of 50 patients(12%) had an increased titer of IgG-ACA and LA was found in 11 patients(22%). No patients were positive for ACA and LA simultaneously. There was no significant difference in sex, etiology of ESRD, diabetic status, the dosage of heparin during HD or the amount of erythropoietin administered according to the presence of APAs. We could not find any significant correlation between the titer of APAs and age, duration of dialysis, blood pressure, platelet count and biochemical parameters. In the patients with positive ACA, the frequency of VAO was 1.05+/-0.12 episodes/patient year, which was significantly higher than patients without ACA (0.33+/-0.17 episodes/ patient year, P<0.05). In the patients with the presence of LA(1.06+/-0.43 vs. 0.12+/-0.06 episodes/ patients year, P<0.01). The median vascular access survival time in IgG-ACA positive patients (32.7 months) was significantly decreased compared to 66.8 months in IgG-ACA negative group. CONCLUSION: Our data suggest that the presence of APAs (ACA and/or LA) affects the event-free vascular access survival in HD patients. Therefore the evaluation of APAs status have to be included in the diagnostic strategies for the patients with recurrent VAO. Further studies are necessary to explore the pharmacologic intervention method to decrease APAs and prevent VAO in HD patients.

Congenital tuberculosis is an infection that is established in the fetus by hematogenous spread or by the aspiration or inhalation of infected amniotic fluid either before or during labor. The diagnosis can be confirmed only if both the tuberculous nature of the lesion and the antenatal origin of the infection can be proved. The authors analysed roentgen findings of two cases of pulmonary tuberculosis, thought to be congenital; 1. Diffuse distribution of nodular densities and some confluent densities were seen in the entire lungs in the inital film.The pulmonary markings were decreased in some degree. 2. Air bronchogram was noted. 3. Hepatosplenomegaly was associated.

BACKGROUND: Ethyl crbmate(EC) has been identified at low microgram quantities in various fermented beverages, destiled products and tobacco smoke. EC has long been known as a carcinogen. Oxidation of the ethyl group of EC is followed by dehydration to yield the carcinogen vinyl carbamate (VC). This is further oxidized to vinyl carbamate epoxide(VCO). VC and VCO proved to be much more carcirogenic than EC. OBJECT: The objective of this study is to compare the potency of carcinogenic ability and histologic changes in skin tumors induced by EC, VC, or VCO. METHODS: In this exeriment, the tumor induction was performed by painting the mouse skin once a week for five weeks with EC, VC and VCO solution, and then 12-0-tetradecanoyl-phorbol-13-acetate(TP2) was treated in the same manner twice a week for 35 weeks. We biopsied the skin at B 0, 15, 25, 30 and 35 weeks and stained the specimens with hematoxylineosin. RESULTS: The time period for the first appearance of papilloma was 6 weeks in the VC-TPA and VCO-TPA group, but, 15 weeks in the EC TPA group. The average number of papilloma showed a statistically sign.ficant difference after 15 weeks between the EC-TPA, VC-TPA and VCO-TPA group. The occurrence of keratoacanthoma and squamous cell carcinoma was 16 and 21 weeks respectively. Histologic changes, such as epidermal layers, pseudohorncysts, degree of hyperkeratosis, hypergranulosis, dysplasia and dyskeratotic cells were more prominent in the papil loma than in the non-papilloma lesion. Dermal changes disclosed similiar findings, that is, increased dermal thicknes, proliferation of vessels and hair follicles, and fibrosis of the dermis. Squamous cell carcinomis and keratoacanthomas were produced only in the VCO-TPA group. CONCLUSION: From the above results it is concluded that VC and VCO have a more potent carcinogenic potential than EC. Various skin tumors, such as papilloma, keratoacanthoma or squamous cell carcinoma were prorduced by the above carcinogens.
