BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

Pigmented Bowen's disease (PBD) is a rare variant of Bowen's disease(BD). Most of the reported cases showed pigmented patches or thin plaques. Thus its clinical manifestations may simulated other various pigmented skin lesions. We experienced 2 cases of PBD in patients with multiple BD developed after taking Korean proprietary pills (KPP, "Hwan-Yak"), which were suspected to contain certain amount of arsenics. Both patients also showed arsenical keratosis on their palms and soles. The darker pigmentation of the PBL led us to differentiated them from melanoma.

It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less that 50% of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma, which is resistant to the systemic chemotherapy.

Individual tumors, even those of the same histologic type, show varying sensitivity to specific cytotoxic agent. Therefore, sensitivity testing assume an increasingly important as an orientational aid in planning chemotherapy. In the past decade there have been many attempts to develop a chemosensitivity test that would predict the clinical effectiveness of various chemostherapeutic agents against human neoplasms. In the United States National Institue's anticancer drug screening program, a colorimetric assey based on the ability of live cells to reduce a tetrazolium-base compound(MTT) to a blue formazan product was used. There has been an increase in reports of a chemosensitivity assay that use tetrazolium dyes and current the assay is in use in our country. The efficacy of several anticancer drug (vincristine sulfate, Etoposide, doxorubicin CDDP) were evaluated using the in vitro chemosensitivity of MTT assay with two cancer cell lines (MOLT-4, KHOS/NP). The follows obtained. 1) CI50 on MOLT-4 are 0.55ng/ml and 0.81ng/ml for vincristine and oncovin, 142.30ng/ml and 78.75ng/ml for lastet and vepesid, and 19.75ng/ml, 20.43ng/ml and 8.66ng/ml for ADR, ADM and adriblastin, respectively. 2) CI50 on KHOS/NP are 691.35ng/ml, 873.73ng/ml, 1,205.22ng/ml, 768.81ng/ml and 672.19ng/ml for cisplan, cisplatin, cispatin, platinol and cisplatin G, and 9.22ng/ml, 11.46ng/ml and 4.28ng/ml for ADR, ADM and adriblastin, respectively. In conclusion the MTT dye reduction assay to anticancer drug sensitivity using short-term microplate culture might serve as a reliable tool for the selection of effective chemotherapeutic agents in patients with cancers.

To identify the problems in child rearing practice of employed mothers in urban poor area, all of 201 women with children under 6 years old living in Yun San 3 Dong, a poor area of Pusan city, were interviewed with a questionnaire by a trained interviewer from 10th April to 10th May 1989. Among 201 women, 51 women were employed and 150 women were unemployed. Of the employed mothers 78.5% got their jobs because of economical need and 31.4% of them worker for 60-69 hours per week. Their average monthly income was 100,000-190,000 Won in 33.4% and 200,000-290,000 Won in 25.4%. Breast milk was fed in 66.0% of the children of unemployed mothers while 49.0 of the children of the employed mothers were breast-fed (p<0.05). The most common reason for not breast feeding was shortage of breast milk among unemployed mothers (58.9%) but that of the employed mothers was their job(63.6%). The basic immunization for children was completed in 70.5% of children of employed mothers as compared with 82.0% of the children of the unemployed mothers were completely immunized (p<0.1). Accident experience rate of children among the employed mothers was 23.5% and that of the children of the unemployed mothers was 17.3%. The most common cause of accident in children of the unemployed mothers was carelessness while they were playing(34.6%) but in children of the employed mothers it was traffic accident(25.0%) and falling(25.0%). Most of the traffic accidents took place while the children's brother or sister of age under 14 years were baby sitting. When the accident took place 73.1% of the unemployed mothers were just at home, but 58.3% of the employed mothers were out of home for work. In case of the employed mothers, 58.7% of their children were looked after by an adult mainly grandparents, 15,7% by the children's brothers and sisters under 14 years old, and 3.9% of the children were left alone. A majority of the unemployed mothers wanted to get a job if someone could take care of their children. To facilitate the women employment and for the safety and health of the children, good nurseries for working mothers need to be established at a cost they can afford.

Transhiatal gastric transpositions were performed in two case of long gap esophageal atresia without tracheoesophageal fistula. The patients were a 12 months old female and an 18 months old male. Stamm type gastrostomies were performed at other hospitals in both cases. The stomach was mobilized preserving the right gastric artery, the right gastroepiploic artery and spleen. The proximal and distal esophageal pouches were excised by transcervical and transhiatal route, respectively. The mobilized stomach was pulled up to the neck through esophageal hiatus and posterior mediastinal route. The esophagogastrostomy, the only one anastomosis of this procedure, was performed in the neck. There was no clinical evidence of anastomotic leakage, stricture, regurgitation, difficulty of gastric emptying, hoarseness or respiratory problem. Transhiatal gastric transposition seems to be a safe and easy alternative surgical procedure for esophageal replacement in long gap esophageal atresia.
