PURPOSE: Factors affecting the response to surfactant replacement therapy are considered as types of surfactant, and strategies of treatment including prophylactic vs rescue therapy, single vs multiple doses, methods of mechanical ventilation, and modes of surfactant delivery. Among those factors, response to surfactant replacement therapy according to the modes of surfactant delivery was rarely studied in the world. In preterm infants with RDS, we studied the efficacy and adverse effects of surfactant replacernent therapy according to the differences in the modes of surfactant delivery. METHOD: Preterm infant weighing 500-2,500g with RDS who required assisted ventilation were divided into two groups. One group is as follows five fractional doses with five positional changes after removal from ventilator by feeding tube technique. The other group is as follows; two fractional doses with two positional changes by side-port adaptor technique. Of the 30 infants enrolled, 15 were randomly assigned to each group. We compared the respiratory indices, chest radiologic response, clinical outcome after surfactant replacement, and adverse effects during dosing procedure. RESULT: There were no diffrences of patient profile between two groups. There were significant improvernent in FiO2, a/APO2, MAP, OI, and chest radiologic response following surfactant replacement therapy in both groups. No significant differences were noted in the adverse effects during dosing procedure and incidence of complication. CONCLUSION: In initial phase of RDS treatment with surfactant replacement therapy, two fractional doses with two positional changes by side-port adaptor technique improve respiratory indices, radiologic response without dernonstrable harmful effects as five fractional doses with five positional changes after removal from ventilator by feeding tube technique, however two fractional dosing procedure is more recommendable because of #more simple and convenient procedure.

Pemphigus foliaceus is a chronic vesiculobullous dermatosis which seems to be an autoimmune etiology, and favorable results are usually able to obtain with massive doses of corticosteroids administration and Imuran or other anticancer drugs. Two cases of typical pemphigus foliaceus, who showed cutaneous candidiasis, one with clinical improvements, and the other one who had lung abscesses of aspergilli as a complication of the long-term corticosteroid treatment, have been presented. The diagnosis of pemphigus foliaceus was confirmed by histopathologically subcorneal bullae containing acantholytic cells, also Tzank test and Nikolsky's sign. First case, 37 year old man who has the history of corticostcroid therapy for 3 years tor rheumatoid arthritis, was treated with high dosage of prednisolone and antibiotics with nystatin for cutaneous candidiasis, but lung abscesses of aspergilli developed while we couldn't even notice its progress and he died suddenly because of it although skin lesions showed marked improvement. Second case, 36 year old house wife who has the history of recurrent aphthous stomatitis like eruptions was recovered from pemphigus foliceus after steroid treatment and cutaneous candidiasis after using antibiotics and nystatin. As the complication of corticosteroid therapy, cushingoid feature, blurred vision, and cutaneous candidiasis were occurred in both patients, especially in the first case, hyperglycemia and metabolic alkaloses were developed. And so, as mention of Saunders, we checked the patient's complete history, body weight everyday, and CBC and occult blood every week, but urine sugar or blood sugar and chest X-ray not periodically. We used anabolic agent for osteoporosis, antibiotics, mycostatm, diuretics, and antacid regimen, but failed to deveIopment of aspergillosis.

These are the first reported cases of granuloma faciale in two Koreans. Unilateral, slightly elevated violaceous plaque with illdefined margin on cheeck since 20 years ago was observed in 36 year old house-wife, and 40 year old male has had bilateral plaques on both cheek areas since 10 years ago, These plaques were showed the typical histological appearance of granuloma faciale respectively on both of two patients. Literature was briefly reviewed for the discussion of clinical and microseopic findings of this disease. Both patients were treated by intralesional injections and ointment of steroid with relative clinical improvements.

To stydy the parameters of preload, afterload, and contractility of the heart, we evaluated 10 mitral stenosis, 5 mitral stenoinsufficiency, and 5 mitral stenosis with aortic insufficiency by measuring the external energy potential, external mechaical work, and external energy potential to PVa(Pressure-volume Area) ratio with non-invasive method, echocardiography and carotid pulse tracting. The results are summarized as follows; 1) External energy potential of mitral stenosis was significantly higher than that of MSI or MS with AI. 2) External mechanical work of MSI or MS with AI was significantly higher than that of Ms. 3) External energy potential to PVA ratio was signifiantly higher in the MS, but there was no significantly difference between the MSI and MS with AI. According to the above results, external energy potential to PVA ratio with echocardiogram and carotid pulse tracting was good parameters of preload, afterload, and contractility. And this method may used bed-side monitoring in the clinical area.

A case of glomus tumor was reported with literature review. 36 year old Korean male has had a single corn sized painful nodular eruption on flexor surface of right side forearm since 2 years ago. This single nodule was confirmed histopathologically as glomus tumor but patient had not any trauma and injury history. Simple surgical excision was very excellent for complete cure of this tumor.

We analyzed neurodevelopmental outcome data of 36 selected studies. Data of individual studies were pooled by birth weight group: <800g, <1.000g, <1.500g and by time period of birth year: Period I (pre-intensive care era), 1960-67:Period II (beginning period of intensive care), 1968-76: and Period III (established period of intensive care), 1977-87. In all weight groups, survival and intact outcome rates based on live birth have progressively improved over the three period. The major neurodevelopmental handicap rate of the <1,500g decreased in Period III vs. Period I and Period II (66,70, and 45 per 1,000 live births in I, II, and III, respectively). However, the major handicap rate in the <800g and the <1,000g live births increased: in the <800g, from 48 per 1,000 live births in Period II to 101 in Period III and, in the <1000g, from 28 per 1,000 live births in Period I to 67 in Period II and 73 in Period III. Increases in major handicap rate in two lower weight groups were predominantly the effect of increasing number of survivors over these periods and had little to do with the change in handicap rates in the survivors. In the <1,500g, the magnitude of reduction in handicap rate in the survivors was sufficient to overwhelm the effect of increased survival, resulting in a reduction in the number of major handicapped children. We conclude that based on the currently avaiable reports, neonatal intensive care has provided very low birth weight infants with a reduction in mortality, an increase in intact outcome, and decrease in the number of major neurodevelopmentally handicapped children. We try to estimate the trend of major neurodevelopmental handicap and intactoutcome of infants with birth weights <1,500g in Korea and speculate that major handicap rate have progressively increased over the three period in spite of increase in intact outcome.

We studied the effects of chronic hyperoxia (>95% oxygen for 14 days) in change of body weight, wet to dry lung weight ratio, and morphologic changes of lung tissue compared with that of room air (21% oxygen for 14 days) in Sprague-Dawley neonatal rat pups. The results were as follows: 1) In neonatal rat pups exposed to room air (normoxia group), body weight of initial 3 days of neonatal rat pups was 9.18 0.18g, and body weights of developing rat pups exposed to room air for 7, 10, 14 days were 14.07 1.90, 17.00 2.09, 23.07 1.93g respectively. In neonatal rat pups exposed to hyperoxia (hyperoxia group), body weight of initial 3 days of neonatal rat pups was 9.35 0.80 g, and body weights of developing rat pups exposed to hyperoxia for 7, 10, 14 days were 11.06 1.31, 12.64 1.77, 15,41 1.65 g respectively. These results suggest that changes of body weight in developing rat pups were stunted significantly in the hyperoxia group compared with normoxia group during 14days-experiment (p<0.01). 2) No appreciable difference of wet to dry lung weight ratio was noted at initial 3 days of neonatal rat pups between normoxia group and hyperoxia group, but considerably increased wet to dry lung weight ratio was noted significantly at 7 days of exposure in the hyperoxia group compared with the normoxia group (p<0.05). The difference of wet to dry lung weight ratio was not significant at 10, 14 days of exposure between normoxia group and hyperoxia group. These results suggested that relative water content of wet lung was at a peak at 7 days of exposure in hyperoxia group. 3) The lung from developing rat pups exposed to room air for 7 days had many small alveoli and numerous septal buds. However, in the lung from developing rat pups exposed to hyperoxia for 7 days, presence of pink staining material within the lumen of the air spaces (proteinaceous edema fluid) and increased interstitial cellularity due to infiltration by macrophages and neutrophils was observed, and these findings suggested acute exudative lung injury. 4) In most lungs from developing rat pups exposed to room air for 14 days, much increased alveolarization including the secondary septal bud formation was observed. However, in most lungs from developing rat pups exposed to hypeoxia for 14 days, increased septal and interstitial cellularity and thickness and interstitial fibrosis were observed significantly compared with normoxia group (p<0.01). In conclusion we could make a experimental animal model which had similar histopathologic finding of bronchopulmonary dysplasia in human infant and this model will be useful for research of pathogenesis of bronchopulmonary dysplasia.
