We know that irrigating fluid used during transurethral resection of prostate (TURP) is rapidly absorbed through open prostatic venous channels in large amount. The TURP syndrome is symptom complex of hypervolemia & hyponatremia (below 130 mEq/1) due to absorption of irrigating fluid. We studied the change of serum sodium, potassium and symptom of hypervolemia during the perioperative period, in 35 patients undergoning TURP. The aim of this clinical study was to examine the possible relation between the irrigating fluid absorption & the development of hyponatremia after TURP. The results were as follow. 1) Though p value was not acceptable, there waa numerical correlation between the weight of resected prostate and the amount of irrigating fluid. 2) TURP syndrome and severe sodium change were not reported in our studiea, 3) We through the cause of above results that operation time & minimal use of irrigating fluid & minimal bleeding due to advanced operative technique, adequate fluid therapy, and intenaive monitoring of vital sign & physiologic change of patients.

Since malocclusion affects a large segment of the population, it is by definition a public health problem. The etiology ana treatment of malocclusions have been studied by clinicians; however epidemioloic aspect of tile problem have been neglected. This study was undertaken using Angle's classification to obtain and to evaluate epidemiologic data on the prevalence of malocclusion in a group of 2,378 Yonsei University students, 17 to 23 years of age. All freshmen were selected, except for those students receiving orthodontic treatment and those few with too many missing teeth which prohibits classification by Angle's method. The following results were obtained: 1) Almost 91% of students had malocclusion of the teeth severe enough to require correction. 2) There was a statistically significant difference in malocclusion between males and females(93.66% malocclusion in males, 79.13% malocclusioa in females). 3) Crowding was most pravalent in class I malocclusion. 4) There appeared to be a specific association between the number of lost first molars and Angle's classification. 5) In this study, more class II, Div.2 malocclusion appeared than in Massier's and Frankel's study of Caucasians, which used similar criteria. Class III malocclusion was more prevalent than normal occlusion in the Korean students studied, but in Caucasians' normal occlusion was more prevalent.

STUDY DESIGN: A retrospective study. OBJECTIVE: To analyze the clinical significance of the radiolucent zones surrounding pedicle screws. SUMMARY OF LITERATURE REVIEW: Clear zones have been suggested in pseudoarthrosis and a loss of fixation. However, few reports have clearly described the long-term course and clinical significance of clear zones. MATERIALS AND METHODS: The clear zones were evaluated in 399 patients with pedicle screw fixation after 6 months, 1 year, 2 years and 3 years. The patient was considered to be clear zone positive when 1 mm or greater circumferential lucency was confirmed around a screw on film from 2 or more directions. The time-course of the clear zones was examined with regard to age, number of levels fused, bone union, fusion method and reoperation. RESULTS: After 6 months, clear zones were observed in 124 patients (31.1%) but the clear zone-positive rate decreased with time. Clear zones were observed in 89 patients(22.3%), 44 patients(11.0%) and 41 patients(10.3%) after 1 year, 2 years and 3 years, respectively. No new clear zones had developed after 6 months. At the final follow-up, pseudoarthrosis was observed in 12 patients(3.0%). Among them, 11 were clear zone-positive and 1 was clear zone-negative. There was a statistically significant relationship between the clear zone-positive rate and multi-levels, older age and nonunion during following up. In addition, there was a relatively lower clear zone-positive rate in posterolateral fusion combined with posterior lumbar interbody fusion than only posterolateral fusion. However, the difference between them was not statistically significant. CONCLUSION: The presence of clear zones does not always mean pseudoarthrosis but clear zones persisting for more than 2 years after surgery have a higher rate of pseudoarthrosis.

OBJECTIVE: Our purpose was to compare the clinical efficacy of intravaginal misoprostol and that of intravenous sulprostone for termination of second-trimester pregnancy. METHODS: The patients were assigned to misoprostol and sulprostone group, and the misoprostol group was further divided into two groups according to gestational age. In the misoprostol group, the patients at or before 20 weeks of gestation received 400 microgram of intravaginal misoprostol every 4 hours until labor pain was established, 200 microgram every 6 hours after 20 weeks of gestation. In the sulprostone group, intravenous sulprostone was infused at the speed of 100 microgram/hr after cervical ripening with 3 mg of intravaginal dinoprostone. RESULTS: At or before 20 weeks of gestation, the median time from induction to completion of termination was longer, but the success rate within 24 hours was less in the misoprostol group than in the sulprostone group (18.75 vs. 7.15 hours, p=0.015; 50% vs 92%, p=0.014, respectively). After 20 weeks, there was no significant difference in median induction time or success rate within 24 hours (5.54 vs. 8.0 hours, p>0.05; 100% vs. 100%, p>0.05, respectively). There was no significant difference in the prevalence of complication or change of hemoglobin after termination between two groups. CONCLUSION: Sulprostone may be more effective for termination of pregnancy at or before 20 weeks of gestation and misoprostol may be as effective as sulprostone after 20 weeks of gestation. But considering less cost and complication, the efficacy of misoprostol should be further investigated for termination of second- trimester pregnancy.

Appendiceal intussusception is a very rare disease that is found in only 0.01% of patients who have undergone an appendectomy. Clinical symptoms vary but include acute appendicitis symptoms such as right lower quadrant abdominal pain or repetitive right lower quadrant crampy pain. Some patients are asymptomatic. Operative treatment is necessary to reduce an appendiceal intussusception in adults, but there is a debate about how to perform the reduction. Successful colonoscopic reductions have been recently reported for some cases. We report a case of appendiceal intussusception that was diagnosed, reduced by colonoscopy, and histologically confirmed as a mucinous cystadenoma after the operation.

Hematemesis is not infrequent occurences in the neonatal period. Physician's first task is to determine whether this blood is maternal in origin or whether the infant is bleeding internally. Fetal blood indicates one of a variety of lesions and its source may be difficult to determine. The causes are esophagitis, peptic ulcer of the stomach or duodernum, hemorrhagic disease and pulmonary hemorrhage etc. We have experienced a case of massive hematemesis that occured in a 1 day of life. we conducted 24 hour pH monitoring, upper gastrointestinal barium series, and endoscopy with biopsy. this case showed esophagitis due to gastroesohageal reflux and errosive gastritis by above procedures. If there is hematemesis during the neonatal period, the esophagitis and gastritis should be considered.

Hemangioblastomas in the pituitary stalk are especially rare. Most pituitary stalk hemangioblastomas reported in the literature were associated with von Hippel-Lindau (VHL) disease. Here, we report only the 3rd case of sporadic pituitary stalk hemangioblastoma diagnosed in a 60-year-old woman. Despite the danger of potential complications due to excessive vascularity or proximity to important neural structures, the tumor in our case was successfully removed while preserving pituitary function. In this case, complete surgical excision was shown to be an effective treatment option for symptomatic pituitary stalk hemangioblastoma, and we suggest careful evaluation of any highly enhancing mass with a signal void in the pituitary stalk preoperatively, even if no VHL disease is evident.

OBJECTIVE: This study was to evaluate the association of the G1691A mutation of factor V gene with preeclamptic patients in Korea. METHODS: Factor V genotype were determined in 113 preeclamptic patients and 100 normotensive pregnant women. A 267 base-pair DNA fragment of the factor V gene that includes nucleotide 1691 was amplified by PCR. PCR product was digested with MnlI restriction enzyme and the fragments were analysed by electrophoresis using 2% agarose gel. RESULTS: The difference of genetic and allelic frequencies between two groups could not be mentioned because all women were G1691G homozygotes. There was no individuals with mutant allele among preeclamptic patients and control women. CONCLUSION: There was no evidence of association between preeclampsia and factor V gene polymor- phism in Korean population.
