Potter's syndrome including bilateral renal agenesis or polycystic renal disease, bilateral pulmonary hypoplasia and characteristic face was first described in 1946. Although a great number of cases of Potter's syndrome was reported, Potter's syndrome with adult polycystic kidney disease(Potter type III) was very rarely found. In this report, we described an autopsy case of Potter's syndrome having adult polycystic kidneys disease, bilateral pulmonary hypoplasia and characteristic face in conjunction with multiple hepatic cysts, features of congenital hepatic fibrosis and a pancreatic cyst. Microscopically, all cysts were lined by cuboidal epithelial cells, showing positive for epithelial membrane antigen and cytokeratins.

Darier's diseaae is relatively rare dyskeratotic and inheritable dermatoses of an. autosomal irregular dominant gene. The authors observed one case of typical Dariers disease with the family hietory of three generatian of autoaomal daminant trait. 22 year-oid patient we observed has had the generalized pruritus and dark dirty and warty patehes distribnted almost on the whole skin surface especially on trunk, back and face for about 10 years. Histopathologically, the lesion showed lacunae, corps ronds and grains which are compatible with typical Dariers disease.

Verrucous hemangioma is congenital hemangioma, which is structural varients of capillary or cavernous hemangioma. And it is vascular malformation, in which reactive epidermal acanthosis, papillomatosis, hyperkeratosis develope secondarily. Though foreign anthors have reported some cases of this disease, it is rare hemangioma and it never has been reported in Korea. This 13 year-old, healthy female patient has erythematous patchs on her left knee at birth. It grew become coin to egg sized. Because of verrcous iuflammatory reaction of irregular verrucous surfaced plague, the lesion become necrotic thick crusty plague with severe offensive odor and patient complained of severe pain & motion limitation on her left knee. Urinalysis, C B C, chest PA were within normal limit. PPD test was negative. Lt. knee AP & lat. revealed. Marked destroyed soft tissue on anterior portion of Lt. knee and no bony pathological changes were demonstrable. Histopathologica.11y, hyperkeratosis, parakeratosis, acanthosis, papillomatosis in the epidermis and numerous capillary lumina, capillary dilatation, proliferation of endothelial cells and mild infiltration of inflammatory cells in the Dermis. And fibrosis in the Dermis & Subcutaneous tissue are seen.

Juvenile Xan anuloma is granulomatous, benign disseminated Xanthomatous disease, which i r cytosis of unknown origin, due to lipid, metabolism disturbance. Spontaneous remi. is possible authors have reported some cases of JXG involving only skin or combii extracutaneous lesions, In our country, cases involving onIy skin have bcen reported. This I-year-old norered healthy male baby has yellowish brown coloxed pinhead to rice sizeci gers of well defined. round, dome shaped smooth surface in face, trunk, lower abdomen without any subjective symptomes. Serum lipid level i iid chest p-A,urinalysis, CBC, L.F.T. are normal. Family history showed ific finding and physical examina.tion shows nothing remarkable except for skeen lesions.

PURPOSE: In the treatrnent of respiratory distress syndrome, Infants are often exposed to hyperoxia. It can generate oxygen free radical, damage to lung and bronchi, and inactivate pulmonary surfactant(PS). Antioxidant therapy in animal and human models has been tried to overcome this detrimental effects. We hypothesized that the addition of oxygen free radical such as hydrogen peroxide(H) could compromise surface active properties(SAP) of PS and that further addition of antioxidant such as catalaseR(CAT, Sigma chemical, St. Louis) could recover SAP. METHODS: We prepared combinations of mixtures with SurfactenR(S-TA, Tokyo Tanabe, Japan), H202 and CAT. 1)0.625mgPL(phospholipids)/ml or 1.25mgPL/ml S - TA and H202 were mixed to the final concentrations of 0.1 and 1mM H respectively, and incubated at 37C for one hour. 2) 0.625mgPL/rnl S - TA, H202 and CAT 10U were mixed to the final concentrations of lmM H202, and incubated at 37 degree C for one hour. We used Pulsating Bubble Surfactometer (Electronetics, NY) measure in vitro minimum and maximum surface tensions(ST) and area-surface tension relationship. RESULTS: 1) For 0.625mgPL/ml S-TA and 1mM H mixture minimum. ST after 5 min of pulsation increased significantly(P=0.007) and the area-surface tension curve was deformed. But they were comparable to control levels for 1.25mgPL/ml S-TA. 2) When CAT was added to 0.625mgPL/ml S-TA and 1mM H mixture, the resultant minimum ST after 5 min of pulsation dropped to the control levels with recovery of hysteresis curve(P=0.0001). CONCLUSION: PS could be inactivated by addition of high concentrations of H but SAP can be recovered either by increasing PS concentration or by further addition of antioxidant CAT. Therefore, we suggest that in case of suspected surfactant inactivation an increase in surfactant concentration or administration of antioxidant must be considered.

PURPOSE: Antenatal steroid(ANS) therapy in premature infants is an effective therapeutic strategy in reducing the incidence of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and patent ductus arteriosus. For premature infants to gain improved survival, adequate weight loss during early postnatal days and maintenance of electrolyte balance is important, however, it is uncertain that ANS affect them. We hypothesized that ANS augment fluid and electrolyte balance and dinical outcome of very low birth weight(VLBW) who had received restricted fluid regimen. METHODS: Mechanically ventilated VLBW infants who survived over 30 days were selected. We reviewed medical records to compare weight loss, urine output, electrolyte concentration, blood pressure during five days of life and clinical outcome between premature infants who received ANS(n=15) and who were not(n=58). RESULTS: Gestational age, birth weight were similar between two groups. Volume of administered fluid, urine output, and initial weight loss during first five days of life were similar, however, weight loss on postnatal day five were lower in study group than control group(p=.039). Blood pressure, serum sodium concentration, serum potassium concentration, and urine specific gravity were similar between two groups. Incidence of respiratory distress syndrome was lower in study group(20%) than control group(48%)(p=.041), however, incidence of sepsis were greater in study group(33%) than control group(7%)(p=.029). CONDUSION: ANS did not affect fluid and electrolyte balance of very low birth weight(VLBW) infants who had received restricted fluid regimen. ANS decreased the incidence of respiratory distress syndrome in this population, however, increased the incidence of sepsis.

The significance of cervical erosion with benign cellular change on Papanicolaou smear has not been evaluated. A retrospective review of 430 coloscopically directed punch biopsies performed over 15 months revealed 206 cases who had a benign cellular change on cytologic smear. Of these 206 smears, 48(23%) had clear cervix without erosion, 99(48%) had mild erosion on cervix, 41(20%) had moderate cervical erosion and 18(9%) had severe cervical erosion. The false negative rate that revealed more than mild dysplasia on histologic diagnosis was 2% in patients without cervical erosion, 3% in patients with mild cervical erosion, 5 % in patients with moderate cervical erosion, and 11% in patients with severe cervical er- osion. Koilocytotic change that suggested human papilloma virus infection was 17% in each group regardless cervical erosion. In conclusion, benign cellular change on Pap smears in patients with severe cervical erosion may be associated with significant cervical cancer pathology.
