PURPOSE: To compare the usefulness of gadolinium-enhanced excretory MR urography using breath-hold three-dimensional fast imaging with steady state precession (3-D FISP) with conventional MR urography using the half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequence in the evaluation of obstructive uropathy. MATERIALS AND METHODS: Twenty-three patients in whom ultrasonography (US) and/or intravenous urography(IVU) revealed signs of urinary obstruction were enrolled in this study. Fifteen were men and eight were women, and their mean age was 54 (range, 21 -80) years. All MR images were obtained using a 1.5-T MR unit. MR urography using the HASTE technique (MRU) and gadolinium-enhanced excretory MR urography using the 3D-FISP technique were performed, and in all cases, reconstructions involved maximum intensity projection. For contrast-enhanced MR urography (CEMRU), images were obtained 3, 5, 20, and 30 minutes after the administration of intravenous contrast media, and for selected cases, additional images were obtained until 24 hours after contrast media injection. For qualitative analysis, two experienced radiologists compared CEMRU and MRU in terms of their diagnostic value as regards the level and cause of urinary obstruction, and morphologic accuracy. In addition, signal to noise ratio (SNR) and contrast to noise ratio (CNR) of the urinary tract at each anatomic level were quantitatively analysed. RESULTS: Quantitative analysis showed that in terms of SNR and CNR of the urinary tract at the level of the mid and distal ureter, CEMRU using 3-D FISP was better than MRU using HASTE (p<0.05). Qualitative analysis indicated that for the depiction of the whole length of normal ureter, and detection of the level of obstruction, anatomic anomalies and intrinsic tumors, 3-D FISP was superior to HASTE. There was, however, no difference between these two modalities in the diagnosis of ureteral stone and the degree of hydronephrosis. In addition, 3-D FISP was better than HASTE for the assessment of filling defect, but the difference was not statistically significant. CONCLUSION: Breath hold 3-D FISP is a very valuable tool in the evaluation of obstructive uropathy. It not only depicts very clearly the anatomy of the urinary tract system, but also provides qualitative information on renal function. We believe that CEMRU using 3-D FISP is a valuable diagnostic approach which can be added to those already available for the workup of obstructive uropathy.

OBJECTIVES: Our purpose was to evaluate the efficacy of pelviscopic classic intrafascial supracervical hysterectomy (CISH) & compare it with total abdominal hysterectomy (TAH). METHODS: We analyzed retrospectively, the clinical data of 1126 patients admitted from January 1993 to December 1998, at 11 university or general hospitals in Korea, for CISH group and 363 patients admitted from January 1993 to December 1998, at Chung-Ang university hospitals, Seoul, Korea, for TAH group. These patients were operated on with the indication of benign uterine disease without cervical malignant lesion. The patients with malignant cervical lesion were excluded in this study. RESULTS: (1) The average age of CISH group was 42.2 (range 24-63) years old and TAH group was 46 (range 31-54) years old. (2) The mean operative time was 150.7+/-49.9 (mean+/-SD, range 55-395) minutes in CISH group and 133.8+/-35 (mean+/-SD, range 65-350) minutes in TAH group. The mean estimated blood loss was 206+/-183.6 (mean+/-SD, range 20-2000) ml in CISH group and 596+/-452.3 (mean+/-SD, range 100-6500) ml in TAH group. The mean hemoglobin change was 1.52+/-0.98 (mean+/-SD, range 0-7) g/dL in CISH group and 3.03+/-1.47 (mean+/-SD, range 0.2-8.4) g/dL in TAH group. The mean time in hospital was 6.3+/-1.43 (mean+/-SD, range 3-18) days in CISH group and 11.0+/-4.08 (mean+/-SD, range 7-37) days in TAH group. (3) Overall complications occured at 5.3% in CISH group and 9.1% in TAH group. (4) Pathologic findings of cervix were benign in 1121 patients (99.6%) and severe dysplasia or carcinoma in situ in 5 patients (0.4%) among CISH groups. In TAH groups, 351 patients (96.7%) had benign cervical lesion and 12 patients (3.3%) had more than oderate dysplasia or carcinoma in situ. In both groups, no invasive cervical cancer was found and the transformation zone of the cervix was included within the resection margin of the cervix in all cases. CONCLUSION: The pelviscopic CISH group has less operative blood loss, less postoperative hemoglobin change, shorter hospital stay and less operative complication than TAH group. Pelviscopic CISH is truly a minimally invasive and organ-preserving surgery and coring out the cervix with the calibrated uterine resection tool may prevent the development of cervical cancer. Therefore, we believe that pelviscopic CISH is preferred in cases of benign uterine diseases, because it lowers operative complications and it may have several benefits compared with total hysterectomy, especially, in women with no pathologic lesion of the cervix.

Midventricular obstructive hypertrophic cardiomyopathy (MOHCM) is a rare variant of hypertrophic cardiomyopathy. Apical dilatation and myocardial infarction can be complicated without significant coronary artery disease. We report a case of apical dilatation in a patient with MOHCM without atherosclerotic coronary artery disease. A 76-year-old woman was admitted for recent cerebral infarction and consulted to cardiologist for abnormal electrocardiographic findings. She had been suffering from exertional dyspnea (NYHA II) for about four years. Two dimentional-echocardiography revealed midventricular obstructive hypertrophy with an apical dilatation and paradoxical jet flow from the apical aneurysm to the left ventricular outflow tract during early diastole. Cardiac catheterization demonstrated dyskinesia in the apical wall with midventricular obstruction and a peak-to-peak intraventricular pressure gradient of 110 mmHg during pull-back from the apical high-pressure chamber to the subaortic low-pressure chamber in the left ventricle. Coronary angiograms showed no significant stenotic lesion of the coronary arteries. She was prescribed oral beta-adrenergic antagonist to decrease the intraventricular pressure gradient.

Colorectal varix (CRV) is a rare cause of lower gastrointestinal bleeding and usually associated with portal hypertension from liver cirrhosis or portal venous obstruction. Idiopathic CRV have no identifiable underlying cause and can only be diagnosed after the cause of portal or mesenteric vein circulation have been excluded. We report a case of idioipathic CRV presented with rectal bleeding for a week. Colonoscopy revealed markedly dilatated tortuous, and bluish veins in the rectum as well as coexistent adenomatous polyp and internal hemorrhoid. Despite extensive investigation, there was no evidence of portal hypertension or any other cause. Family history was also negative. Although blood transfusions were required, the patient remained asymptomatic without further rectal bleeding.

PURPOSE: Chemotherapy is the treatment of choice for small-cell lung cancer (SCLC). Despite the high response rates with first-line therapy, most patients eventually experience disease progression, and finally become candidates for second-line therapy. Topotecan is the only single agent currently approved in the United States for the treatment of a recurrent disease. The aim of this study was to evaluate its efficacy in patients with of previously treated, but relapsed and refractory, SCLC. MATERIALS AND METHODS: Twenty-five patients, who had taken topotecan as a second-line therapy, between March 1999 and October 2002, were reviewed. The patients were divided into two groups: (1) One group were the patients that had failed the first-line treatment within 3 months from end of the chemotherapy (refractory group, RG); and (2) the other group were those that responded to the first-line treatment, but who progressed 3 months after the end of the chemotherapy (sensitive group, SG). Topotecan was administered, intravenously, at a dose of 1.5 mg/m2, within 30 minutes, for five consecutive days every 3 weeks. RESULTS: There was only one partial response in the SG (3.8%), but there were 9 stable diseases, 4 in the SG and 5 in the RG; 15.4 and 19.2%, respectively. The median survivals were 6.9 and 5.2 months in SG and RG, respectively (p=0.162). There were ninety-nine chemotherapy cycles. The toxicities were mainly hematological. There were 26 incidences of Grades III and IV neutropenia, and the non hematological toxicities were mild. CONCLUSION: It was concluded that topotecan is not so effective in the treatment of patients with relapsed and refractory SCLC, despite its predictable and manageable toxicity. The incorporation of topotecan in combination chemotherapy regimens for treatment of SCLC is now warranted.

Gemella morbillorum, an anaerobic-to-aerotolerant Gram-positive coccus, is a normal flora of the oral cavity, respiratory tract, urogenital organ and gastrointestinal tract, and infections caused by this organism are unusual. It has been associated mainly with endocarditis and bacteremia, and rarely with arthritis, spondylodiscitis, meningitis, brain abscess and septic shock. Liver abscess caused by G. morbillorum is very rare, and only a few cases were reported. We experienced a case of liver abscess by G. morbillorum in a 56-year-old woman presented with fever. We report this case with a review of literatures.
