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.

In cross sectional fashion we recoreded the cone response in 98 adult diabetics and 20 normal controls according to the recommendation by the International Society for Clinical Electrophysiology of Vision. The photopic oscillatory potentials were extracted from the cone response by highpass filtering. The clear media and attached retina were criteria for inclusion in this study. The data were statistically analyzed expecting that this procedure may provide a feature that could have some clinical significance. The analysis of variance demonstrated that the summed amplitude of the oscillatory potentials, and second oscillatory potential amplitude were the most sensitive parameters to the diabetic retina. A timing delay in the first oscillatory potential wavelet, and a reduction in the second oscillatory potential amplitude and the summed amplitude of oscillatory potentials were the commonest abnormalities. Hence, the second oscillatory potential amplitude and the summed amplitude of oscillatory potentials may be the most valuable indicator among the photopic electroretinogram parameters representing a quantitative measure of overall retinal dysfunction.
