Eleven cases of juvenile diabetes mellitus who were admitted Seoul National University Hospital from Jan., 1969 to Aug., 1978 were aha1yzed. The mean age of onset was 7 and female to male ratio was 8 to 3 with female preponderance. Four had family history of diabetes, although none had diabetic sibling. Polyuria and polydipsia were noted in all cases as initial symptoms, and symptoms of weight loss (6 cases), disturbances in consciousness (5), generalized weakness (5), anorexia (4) and enuresis (3) were noted in the order of frequency. Leucocytosis was noted in 5 cases, but only 2 among the 4 who had infection revealed leucocytosis, The mean blood glucose level was 320 mg% and serum osmolality was 293 mOsm/L. There was no significant difference in the level of blood sugar and serum osmolality according to the consciousness status. Eight episodes of ketoacidosis occured in 5 cases. Three episodes developed due to discontinuance of insulin and three episodes accompanied infection. The mean blood glucose level was 495 mg% and serum osmolality was 300 mOsm/L in ketoacidosis. The consciousness cleared in average 20 hours and ketonuria disappeared in average 26 hours after the administration of insulin (average 5 units/kg of body weight). At discharge, the average dose of insulin needed was 1.2 U/kg/d. Six patients were followed from 6 months to 6 years. Two developed pulmomary tuberculosis during the period of follow up.

Continence and micturition involve urethral closure. Especially, insufficient strength of the pelvic floor muscles including the urethral sphincter muscles causes urinary incontinence (UI). Thus, it is most important to understand the main mechanism causing UI and the relationship of UI with the urethral sphincter. Functionally and anatomically, the urethral sphincter is made up of the internal and the external sphincter. We highlight the basic and clinical anatomy of the internal and the external sphincter and their clinical meaning. Understanding these relationships may provide a novel view in identifying the main mechanism causing UI and surgical techniques for UI.

A hemorrhagic disease due to prothrombin complex deficiency os described in 4 infants from 1 to 11 months of age. This disease is different from the hemorrhagic disease of the newborn. The main differences are that it is found in an older age group and that intracranial hemorrhages are frequent. Rapid clinical and laboratory response after vitamin K therapy are observed. Severe prothrmbin complex deficiency due to vitamin K deficiency is a accounted for the pathogenesis of bleeding. Possible causes of vitaimn K deficiency are reviewed.

Ultrasound is over 20 khz, which represents the upper frequency limit of human hearing. Acoustic vibrations are generated when piezoelectric materials on the thin disc-shaped transducers expand and contract. Although low frequency ultrasound devices have been used widely in the dermatologic area for a long time, the mechanism and side effects have been overlooked. A low-frequency ultrasound device has many benefits on the cosmetic dermatology area by thermal effect, vibration effect, and increase of transdermal delivery of lipophilic drugs or cosmetics. However, there have been reports of dermatitis, dyspnea, dizziness, and burns after treatment with ultrasound. Therefore, the use of this device should be under a doctor's supervision.

BACKGROUND/AIMS: We studied to evaluate the virological and biochemical responses to lamivudine and to detect YMDD mutants in patients who received long-erm lamivudine therapy. METHODS: We conducted a one-ear trial of lamivudine in 45 Korean patients with chronic liver disease due to hepatitis B virus. The patients were treated with a single oral average dose of 100 mg of lamivudine every day for 12 months. RESULTS: The suppression of serum HBV DNA was sustained in 77.8% of the patients and the normalization of serum ALT in 80%. The proportions of patients with HBeAg seroconversion were 25%. YMDD mutants were detected in 4 of 8 patients who showed sustained HBV DNA and serum ALT response (n=31) and in 3 of 8 patients who showed HBV DNA or serum ALT breakthrough (n=9). The response to lamivudine therapy in HBeAg-egative patients was excellent. CONCLUSION: Lamivudine therapy resulted in a significant virological and biochemical improvements and were well tolerated. But, YMDD mutants were detected during lamivudine therapy.

We studied to know The prognostic factors of Wilms' tumor who admitted to the Seoul National University Children's Hospital from May 1985 to July 1992. We treated Wilms' tumor with surgery, anticancer chemotherapy and radiation therapy according to National Wilms' Tumor Study protocol and analysed survival or relapse rate versus prognostic factors (age at diagnosis, histology, lymph node involvement and stage). As a result, during median follow-up period of 31 months, two year relapse free survival rate was 64% and 2-year overall survival rate was 79%. Two year overall survival rate was 100% in stage I, 83% in stage II and III, 60% in stage IV. This tumor stage was statistically significantly correlated with survival rate(P<0.05). However, other prognostic factor was not correlated with the survival rate(P> 0.05). We concluded that stage is more valuable prognostic factor than age, histology and lymph node involvement.

OBJECTIVES: Our goal was to determine the effectiveness of using the auditory steady state response (ASSR) as a measure of hearing thresholds in infants who are suspected of having significant hearing loss, as compared with using the click-auditory brainstem response (C-ABR). METHODS: We retrospectively analyzed the audiologic profiles of 76 infants (46 boys and 30 girls, a total of 151 ears) who ranged in age from 1 to 12 months (average age: 5.7 months). The auditory evaluations in 76 infants who were suspected of having hearing loss were done via the C-ABR and ASSR. In addition, for reference, the mean ASSR thresholds were compared to those of 39 ears of infants and 39 ears of adults with normal hearing at 0.5, 1, 2, and 4 kHz. RESULTS: The highest correlation between the C-ABR and ASSR thresholds was observed at an average of 2-4 kHz (r=0.94). On comparison between the hearing of infants and adults at 0.5, 1, 2, and 4 kHz, the mean ASSR threshold in infants was 12, 7, 8, and 7 dB higher, respectively, than that in adults. CONCLUSION: ASSR testing may provide additional audiometric information for accurately predicting the hearing sensitivity, and this is essential for the management of infants with severe to profound hearing loss.
