Prognosis and biologic behavior of malignant ovarian tumors have been assessed by clinical staging, morphological grading and many other variables. Recently DNA ploidy measured by flow cytometry has been suggested as an additional important indicator of the tumor behavior and prognosis. The author measured DNA ploidy, S-phase fraction and DNA Index in 36 patients of epithelial ovarian tumors(17 were malignant, and 19 were borderline) by flow cytometric analysis of paraffin embedded tumor blocks. Comparing with FIGO stage, tumor grade, histologic type and others, the author investigated the clinical significance of the results of flow cytometric analysis.

The term "collagenous colitis" was coined by Lindstrom in 1976 to describe the patient with chronic watery diarrhea who had normal rectal mucosa by proctoscopy but who had a thick subepithelial collagenous deposit on biopsy, and now collagenous colitis is recognized as one of the more common causes of chronic diarrhea of obscure origin. But in this country only a few case has been reported. We have seen a 68-year-old man with chronic watery diarrhea with abdominal pain. Physical examination, laboratory and radiologic studies were no abnormal finding. Colonoscopy disclosed grossly normal mucosa through the entire colon but by histologic examination there are chronic inflammation in the lamina propria and thickened subepithelial collagen layer. Symptoms and pathologic findings of patient improved after treatment with sulfasalazine and prednisolone. (Korean J Castraintest Endosc 17: 79-84, 1997)

Syringocystadenoma papilliferum is s rare tumor of disputed origin that was first reorted by peterson in 1892. Theclinical features of syringocystadenoma papilliferum are not constant. It may be present at birth or develop later in life. Its appearance varies from an irregular, flat, grey or reddish area to a grey or dark brown. raised and cauliflower-like surface. Sometimes it is moist, flesh or pedunculated and occasionally a verrucous plaque, or cyst may be seen. The typical lesion occurs most frequently on the scalp, and is a hairless smooth plaque until puberty, when a nodular verrucous transformation occurs. A 39 years old male patient had egg sized (3*5cm) and yellowish red colored verrucous tumor mass on his epigastric area, which had grown up slowly for 7 years. The diagnosis of syringocysyadenoma papilliferum was confirmed by histological examination. We repoet a case of syringocystadenoma papilliferum in unusually large size on the epigastric area.

The lower ureter is not so frequent site of the urinary tract obstruction. In lower ureteral obstruction, the obstruction should be relieved by any method for maintaining renal parenchyme. A clinical studies were made on the 24 ureters of the lower ureteral obstruction. This studies were mainly focused on the method of management by internal stent indwelling. The following results were obtained. 1. In etiology, acquired lower ureteral strictures were most common ; tuberculosis in 10 ureters, radiation in 6 ureters, pelvic lymphadenopathy in 4 ureters, and iatrogenic stricture in 3 ureters. Congenital UVJ stricture was only one ureter. 2. In the method of management, open surgeries were done in 10 ureters and endourologic methods in 14 ureters. 3. In 5 failures of the first management, open surgeries were done in 3 ureters and endourologic methods in 2ureters. The tuberculosis was the most of their etiology. 4. Complications in internal stent indwelled cases were flank pain, severe vesical irritation, migration into the bladder and the obstruction of the lumen of stent.

BACKGROUND: Caudal anesthesia is considered a safe and reliable anesthetic technique for many pediatric surgical procedures. It is well known that extradural clonidine produces analgesia in adult. The purpose of this study is to assess its efficacy in children. METHODS: We randomized 45 pediatric patients aged under 10 years, weighted under 25 kg presented for lower abdominal surgery with duration of operation would be shorter than 2 hours, into three groups of 15 each. After sedation with the use of intravenous thiopental sodium, caudal anesthesia was performed with the use of 1 mL/kg of 0.25% bupivacaine. We allocated randomly the patients who received no additional medication in 0.25% bupivacaine (group I), with epinephrine 1/200,000 (group II), and with 1 mcg/kg of clonidine (group III). The degree of postoperative analgesia was evaluated using the Broadman ""Objective Pain/discomfort Scale"" (OPS) at hourly intervals for 24 hours. RESULTS: Duration of sleep in the recovery room was significantly longer in group III than in group I and group II, and statistical significant difference was found between the group I and group II. Duration of analgesia was significantly longer in group III than in group I and group II. Overall hourly OPS scores were lower in group III than in group I and group II. CONCLUSION: Duration of postoperative analgesia with caudal bupivacaine was increased by addition of 1 mcg/kg of clonidine.

PURPOSE: Pelvic floor muscles play an important role in female sexual function. Urinary incontinence is one of the complex symptoms of pelvic floor relaxation. The purpose of the present study was to evaluate the effects of behavioral treatment on the sexual life variables and quality of life in stress urinary incontinent women. MATERIALS AND METHODS: Fifty women with clinically and urodynamically proven stress urinary incontinence were randomly selected, and treated with functional electrical stimulation (FES) -Biofeedback. The FES-Biofeedback treatment was performed for 20 min per session, 2 sessions a week, for 6 weeks. The treatment consisted of electrical stimulation (35Hz and 50Hz, simultaneously) for 24 seconds, and the biofeedback, composed of 3 phases of contraction, lasted for 32 seconds. The outcome measures on the sexual life variables and quality of life scales were assessed by the Bristol Female Lower Urinary Tract Symptoms questionnaire and a self-developed questionnaire, based on the Brief index of sexual Functioning for women (BISF-W). RESULTS: The general quality of life scores were significantly improved after 6 weeks of FES-Biofeedback (p<0.05). The quality of orgasms, sexual interest, sexual activity and sexual anxiety were significantly improved after the FES-Biofeedback (p<0.05). Changes in the scores for the degree of satisfaction in those variables also showed statistical significance (p<0.05). CONCLUSIONS: Women with incontinence were dissatisfied with their sexual life due to various symptoms associated with their urinary symptoms or symptoms that result from pelvic floor relaxation. The FES-Biofeedback therapy showed positive effects on improving, not only stress incontinence, but also sexual life variables and the life quality.

An epidemiological investigation was conducted on Metagonimus yokogawai infection in Hadong Gun (County), Gyeongsang Nam Do, Korea, and following findings were obtained. Overall prevalence rate of Metagonimus yokogawai infection was 29.1 percent from a total of 1,163 inhabitants examined. By area of river and stream, Seomjin-gang R.: 9.5 percent (out of 95 inhabitants examined) in Jeondo Ri in the lower river, 19.9 percent (156) at Dugog Ri near Hadong town, and 90.8 percent (65) in Tab Ri of Hwagae Myeon where Hwagae-cheon Stream joins; Hwagae-Cheon Stream: 42.2 percent (45) in Yonggang Ri of the middle stream and 27.5 percent (72) in Daeseong Ri of the upper stream; Hoengcheon-gang R.: 54.7 percent (161) in Gojeol Ri of the lower river, 40.6 percent (128) in Hoengcheon Ri of the middle stream, and 5.4 percent (93) in Jungi Ri of the upper stream, and 43.8 percent (89) in Uge Ri located along a tributary of the Hoengcheon-gang R. and 4.0 percent (101) in Jangam Ri which is located about 4 km away from the river; Deogcheon-gang R.: 18.5 percent (54) in Munam Ri; Gwangog-cheon Stream: 2.8 percent (107) in Gwangog Ri. The difference in prevalence rate of the infection by area was correlated with the opportunity and amount of raw eating of sweetfish by the inhabitants in the respective areas. By age and sex, the overall prevalence rate increased from young age group and reached a peak at 20-29 age group and then the rate decreased gradually. In high endemic areas, however, a peak level of the rate lasted up to 40-49 age group in male. On the other hand, in low endemic areas, the rate was significantly lower in female, though moderate level of the infection was seen in male. The overall prevalence rate was higher in male than in female and the difference was greater in middle age groups. The most significant mode of infection by the inhabitants was the raw eating of sweetfish which commonly harbour metacercariae of M. yokogawai during summer through autumn. Besides, it was noted that the infection can be acquired through contamination with the metacercariae on food of various side-dish and kitchen utensils as well as on hands of a cook when such fish are prepared or handled. The inhabitants usually begin to acquire infection from early June of a year when fishing of sweetfish opens and acquire infection more frequently in July and August when fish are caught more productively and favored for raw consumption by inhabitants. From September, sweetfish are no more favored for raw consumption and accordingly are dried and cooked in this season. The infection in the sweetfish Plecoglossus altivelis as the second intermediate host was first observed from May with low level of infection and the intensity of infection in a fish rapidly increased until reaching a peak in October when sweetfish season normally ends. The first intermediate host snail of M. yokogawai in this area was Semisulcospira coreana (Martens) which is widely distributed in the streams and rivers in this locality.
