Diagnosis of adenocarcinoma of the prostate based purely on digital rectal examination will be correct in only 70% of cases. Transitional cell carcinoma also arises in the prostate, as may more rarely sarcoma. The fibrous prostate, granulomatous prostatitis and stone may also result in a prostate that feels firmer than normal. Estrogen or orchiectomy will be of no benefit in these condition and may cause harm. Histological or cytological proof of the diagnosis is essential. Examination of prostatic tissue obtained by biopsy has been used to confirm malignancy or any type, judge the response of a tumor to either hormonal or cytotoxic manipulation and bacteriologic confirmation. The transrectal prostatic biopsy was performed on 48 cases of oriental, from May 1979 to February 1982. The results are as follows. 1. The patients ranged in age from 25 to 82 years old and the percentage of patients more than 50 years old is 85.4% (38 cases). 2. The highest reason of referral for prostatic biopsy is obstructive symptoms (62.5% - 30 cases). 3. As shown in table 3, only in 2 cases the specimens obtained with Silverman needle proved inadequate for a reliable diagnosis even though in 46 cases the specimens were thought to be adequate. In 46 cases, the highest disease is B.P.H. (73.9% - 34 cases), 2nd prostatic adenocarcinoma (17.5% - 8 cases), 3fd chronic prostatitis (4.3% - 2 cases) and normal prostate (4.3% - 2 cases). 4. There were 7 complications of transrectal prostatic biopsy and the hematuria (4 cases) was the most common.

Internal hernia is an unusual cause of the intestinal obstruction. The advances of CT make the diagnosis more easier than in the past. We report one case of internal hernia with herniation of the ileum into the lesser omenturn. The diagnosis could be made when abdominal radiographs showed fixed clustering of the small bowel loops in upper abdomen medial to the stomach. CT and ultrasound showed characteristic interposition of the ileum between the left hepatic lobe and the stomach.

PURPOSE: The purpose of the study was to compare CT with scintigraphy in the detection of parenchymal lesionsof acute pyelonephritis in children, and to assess the diagnostic value of CT. MATERIALS AND METHODS: This studyinvolved 32 children with acute pyelonephritis ; their ages ranged from 1 month to 10 years. Renal CT , TC-99mDMSA planar and SPECT images, and medical records were retrospectively reviewed. We evaluated the number, size,shape, density, and location of pyelonephritic lesions, as seen on CT and scintigraphic images. RESULTS: In 43involved kidneys, 193 parenchymal lesions of acute pyelonephritis were identified. The results of CT were abnormalin 42 kidneys (98%), and those of scintigraphy, in 39(91%). CT showed single or multiple hypoenhancing parenchymallesions ; these were streaky(n=151), wedge-shaped (n=34), or oval (n=8), and ranged from about 3-30mm in maximumdiameter. Abscess (n=5), renal fascial thickening (n=6) and thickening of the bridging septae (n=7) wereassociated. Scintigraphic findings were diffuse or localized area of varying degrees of diminished corticalactivity, and these were more precisely identified on SPECT than on planar images. For the detection of 55 of 193pyelonephritic lesions, CT was more sensitive than scintigraphy ; 29 of the 55 lesions were less than 5 mm indiameter. CONCLUSION: For the detection of pyelonephritic lesions, particularly smaller ones, and for theevaluation of complications such as abscess formation, CT is more sensitive than Tc-99m DMSA scintigraphy. Weconclude that in children with subtle scintigraphic findings who are in serious clinical condition or in whomcomplications are suspected, CT is a useful tool for assessing a therapeautic plan and the prognosis of acutepyelonephritis.

PURPOSE: The purpose of this study was to evaluate the CT findings of acute pyelonephritis (APN) in children and to assess the correlation between these findings, clinical parameters and renal scar development, as seen on follow-up CT scans. MATERIALS AND METHODS: Contrast-enhanced CT scans of thirty children in whom APN had been diagnosed were assigned to one of three groups according to whether an abscess had formed, and then to subgroups on the basis of the number of lesions in the renal parenchyme. Initial CT findings were retrospectively correlated with five clinical parameters (maximal body temperature, fever duration, leukocytosis, pyuria and admission period) and renal scar development, as seen on follow-up CT (n=12). RESULTS: CT scans demonstrated linear, wedge-shaped, low-density renal parenchymal lesions in 35 kidneys of 25 patients and abscesses in seven kidneys of seven patients, but no abnormal lesions in five patients. In the three groups there was correlation between these findings and some clinical parameters (maximal body temperature, fever duration and admission period), but no subgroup showed significant correlation with any clini-cal parameter. Renal cortical scars detected by follow-up CT were more prevalent in patients in whom initial CT demonstrated the presence of an abscess. CONCLUSION: Clinical parameters correlated with the presence of renal parenchymal hypoenhancing lesions and abscess formation, as seen on CT scans, rather than the number of renal parenchymal lesions. Renal cortical scars were more prevalent in patients in whom initial CT revealed the presence of an abscess. Enhanced CT is thought to be useful both for diagnosing APN and for predicting its clinical course in children.

PURPOSE: The purpose of this study is to assess the sonographic findings of Osgood-Schlatter disease with correlation to radiographic findings and to determine value of sonography in the diagnosis of Osgood-Schlatter disease. MATERIALS AND METHODS: The population consist of 22 cases of Osgood-Schlatter disease and 15 healthy subjects of the same age range for comparison. The sonographic study was carried out with real time units equipped with linear probe of 7 MHz frequency. Radiography and sonography were done in all cases and follow-up sonography was performed in 10 cases. RESULTS: The sonographic features of the Osgood-Schlatter disease were swelling of cartilage over the anterior tibial tuberosity ossification center in 16 cases, fragmentation and/or irregularities of the ossification center of the anterior tibial tuberosity in 14 cases, localized thickening of the pateliar tendon in 14 cases, ossicles in the thickened pateliar tendon in 3 cases, and distension of the infrapatellar bursa in 2 cases. Fifteen of 22 cases of Osgood-Schlatter disease had abnormal findings on radiographs and sonograms. Out of 7 cases which had normal radiograph and abnormal findings on sonogram, 6 cases showed pateliar tendon thickening, cartilage swelling, and/or distended infrapatellar bursa and one case showed fragmentation of anterior tibial tuberosity on sonogram. CONCLUSION: Sonographic evaluation of Osgood-Schlatter disease provided a clear picture about pathologic changes in the superficial soft tissues and in the cartilage and also yielded the same diagnostic information on bony change as radiography Sonography is a reliable and useful method for the evaluation of young patients with clinically suspected Osgood-Schlatter disease.

A case of arterial priapism was treated by superselective transcatheteric autologous clot embolization of cavernosal artery 25 days after blunt periheal trauma. No immediate improvement was noted but the priapism subsided on 48th day after the procedure. Normal physiclogic erectlie function was achieved on 53rd day after the procedure, and the period of postprocedure impotence was shortened, as compared with previously reported cases. Autologous blood clot embolization may be an effective treatment method even in delayed priapism, and superselective technique is thought to be more effective to shorten the postprocedure erectlie dysfunction

Primary renal lymphoma is a rare tumor of the kidney that typically presents with bilateral nodular enlargement in the absence of extrarenal masses. We describe MR findings of a case of primary renal lymphoma along with ultrasound and CT findings. MR imaging demonstrated globular enlargement of both kidneys with multilobulated contour and multiple masses which had isosignal intensity on T1WI and low signal intensity on T2WI. The masses enhanced slightly on dynamic contrast enhanced scan.

BACKGROUND: We monitored the prevalence of antimicrobial resistance and the pattern of multiple drug resistance in Escherichia coli isolated from healthy people in the community. METHODS: We performed antimicrobial susceptibility testing on 491 isolates of E. coli from 692 healthy people in Incheon from February to July in 2006. The results were interpreted according to the CLSI guidelines. RESULTS: The highest rate of resistance was observed against tetracycline (46.6%), ampicillin (41.1%), ticarcillin (37.9%), streptomycin (31.0%), and nalidixic acid (23.6%). Twenty six percent of isolates were observed to be resistant to five or more of the antimicrobials tested. CONCLUSION: In order to maintain a low level of antimicrobial use and resistance, the surveillance of antimicrobial resistance in the community would be very important, as it provides epidemical data to set up and control antibiotic guidelines and serves as an early warning for resistance in pathogenic bacteria.
