Patients with signs of benign prostatic hyperplasia undergo excretory urography as a part of the diagnostic measures. The investigation is expected to yield information on the upper urinary tract and pathology of the bladder. But the necessity of excretory urography as a routine study before prostatectomy has been questioned. Herein we analyzed 154 patients who underwent excretory urography before prostatectomy at department of Urology, Masan Koryo General Hospital from January 1990 to December 1992. Of 154 patients, 117(76.0% ) showed normal upper tract with cystogram compatible with benign prostatic hyperplasia, 19(12.3% ) dilated upper tract. 1 (0.6% ) nonvisualized kidney, 9(5. 8%) incidental upper tract anomalies, 12(7.8% ) urolithiasis. Most of these anomalies could not alter the planned therapeutical procedures. We concluded that excretory urography is not always necessary in diagnosis of benign prostatic hyperplasia, but only in selected cases.

A hemangioma is a benign tumor arising in the vessels, but an intrascrotal hemangioma is rare, and a hemangioma of the epididymis is extremely rare. Ultrasound and MRI (magnetic resonance imaging) are mainly used for the diagnosis of an intrascrotal hemangioma, with surgical excision being the appropriate treatment. We report on the case of a 24 year- old-man with a mixed hemangioma of the epididymis.

Giant duodenal ulcer can be defined as a variant of peptic ulceration that exceeds 2 cm at the greatest diameter. The high mortality and morbidity of giant duodenal ulcer are directly related to the resultant perforation, obstruction and massive hemorrhage. The patient usually has a long history of an inadequately treated or neglected peptic ulcer, but this malady is rarely induced by nonsteroidal anti-inflammatory drugs (NSAIDs). A 60-year-old man was referred to us due to epigastric pain. He underwent appendectomy 1 week ago, and he was administered ketorolac (tarasyn(R)) for 5 days to control the postoperative pain. Esophagogastroduodenos copy (EGD) revealed a giant duodenal ulcer encircling the lumen from the pylorus to the postbulbar portion of the duodenum, and he was then treated with proton pump inhibitor. Two weeks later, the follow-up EGD showed complete duodenal obstruction at the bulb. He was treated by laparoscopic gastrojejunostomy. We report here on this case of duodenal obstruction that was induced by the short-term use of NSAIDs.

A NK/T cell lymphoma is highly aggressive lymphoma of a putative NK-cell origin with a predominant extranodal presentation and a rapidly fatal course. CD56 has been reported to be the most reliable marker for a NK/T cell lymphoma. A NK/T cell lymphoma is strongly associated with the Epstein-Barr virus. We report a case of an aggressive NK/T cell lymphoma presenting as a gastric ulcer. A 52-year-old female patient presented with hematochezia and fever. The endoscopic finding showed a gastric ulcer with a recent bleeding stigma. Histologically, the gastric biopsy showed a diffuse infiltration of small or medium sized lymphoma cells with an angiocentric growth pattern and necrosis. The lymphoma cells were CD56+, CD3+, CD20-, which are consistent with a NK/T cell lymphoma. Unfortunately, the patient was discharged without treatment. We report this case with a review of the relevant literature.

BACKGROUND/AIMS: Peristomal infection is the most common complication of percutaneous endoscopic gastrostomy (PEG) insertion. Methicillin-resistant Staphylococcus aureus (MRSA) is the most commonly implicated organism of peristomal infection. The aims of this study were to determine the contribution of nasal MRSA to wound infection in PEG and the predictors of wound infection. METHODS: A prospective study was conducted on patients undergoing PEG between September 2003 and July 2005. All patients received antibiotics prior to PEG insertion. Nasal swabs were taken from a consecutive series of patients prior to PEG insertion. Wound status of the peristomal site were prospectively evaluated at day 1, 3, and 7 following the insertion of PEG. RESULTS: Thirty-one patients underwent PEG insertion (mean age, 66+/-16 years). Ten patients (32.3%) had MRSA-positive nasal swabs. Peristomal infection did not have any relationship with nasal MRSA colonization (p>0.05). Peristomal infection occurred in 4 (12.9%) cases. The rate of peristomal infections was significantly higher in patients with diabetes mellitus (p<0.05). CONCLUSIONS: Nasal MRSA colonization is not associated with the risk of peristomal infections in patients receiving antibiotics prior to PEG insertion. Diabetes mellitus might be the risk factor for peristomal infection after PEG insertion.

PURPOSE: We measured the gastric cancer tissue uPA and plasminogen activator inhibitor-1 (PAI-1) levels and compared them to those of the peripheral and portal blood levels to evaluate the correlation. MATERIALS AND METHODS: Tissue uPA and PAI-1 levels were measured by ELISA assay (Monozyme, Netherland) in paired 85 normal and cancer tissues resected from gastric cancer patients. In 50 patients, blood uPA and PAI-1 levels were measured from pre- operative peripheral and portal blood, post-operative portal blood. RESULTS: Gastric cancer tissue uPA and PAI-1 levels increased from the early stage. The elevated cancer-to-normal ratios of the uPA and PAI-1 were constant from stage I to IV. There were correlations of uPA between normal and cancer tissues (r2=0.38) and between peripheral and pre-resection portal blood level (r2=0.64). There were no correlations between tissue PAI-1 level and blood PAI-1 levels. However, there were correlations in PAI- 1/uPA ratio between cancer tissue and peripheral blood (r2=0.25), peripheral blood and pre- resection portal blood (r2=0.60). CONCLUSION: Even if the cancer tissue levels of uPA and PAI-1 increased from the early stage of gastric cancer, only blood uPA level correlated with tissue uPA level. A modest correlation found in PAI-1/uPA ratio between cancer tissue and blood suggests applicability of blood PAI-1/uPA ratio in predicting tissue uPA, PAI-1 expression.

BACKGROUND/AIMS: The aim of this study was to investigate the relationships between the clinical manifestations and the colonoscopic findings of ischemic colitis. METHODS: From March 2000 to June 2005, the data of 69 patients diagnosed with ischemic colitis were analyzed retrospectively. Statistical analysis was done by dividing the patients into two groups according to involved segments and also by again dividing the patients into two groups according to the mucosal findings that were gangrenous or not. RESULTS: The most common involved segment was the sigmoid colon (82.6%). The levels of total protein and albumin were significantly lower in the multisegmented group than in the non-multisegmented group (p=0.012, p=0.030, respectively), but there was no significant difference in the operation rate between the two groups. The WBC count and the level of serum glucose were significantly higher in the gangrenous group than in the non-gangrenous group (p=0.007, p=0.048, respectively). The operation rate was also higher in the gangrenous group (33.3%) than in the non-gangrenous group (3.5%) (p=0.011). CONCLUSIONS: Evaluating the severity of mucosal damage by colonoscopy may be helpful in predicting the clinical status and prognosis of the patients with ischemic colitis.

Vaccination against hepatitis A virus (HAV) is recommended for patients with chronic liver disease (CLD), but this has been deemed unnecessary in Korea since the immunity against HAV was almost universal in adults. However, this practice has never been reevaluated with respect to the changing incidence of adult acute hepatitis A. We retrospectively reviewed the medical records of 278 patients with acute hepatitis A diagnosed from January 1995 to November 2005 and prospectively tested 419 consecutive CLD patients from July to December 2005 for the presence of IgG anti-HAV. The number of patients with acute hepatitis A has markedly increased recently, and the proportion of adult patients older than 30 yr has been growing from 15.2% during 1995-1999, to 28.4% during 2000-2005 (p=0.019). Among 419 CLD patients, the seroprevalences of IgG anti-HAV were 23.1% for those between 26 and 30 yr, 64% between 31 and 35 yr, and 85.0% between 36 and 40 yr. These data demonstrate that immunity against HAV is no more universal in adult and substantial proportion of adult CLD patients are now at risk of HAV infection in Korea. Therefore, further study on seeking proper strategy of active immunization against HAV is warranted in these populations.

Cap polyposis is a rare intestinal disease that is characterized by the presence of inflammatory polyps consisting of elongated, tortuous and distended crypts that are covered by a 'cap' of granulation tissue. The pathogenesis and proper treatment of cap polyposis are still unclear. We experienced a case of cap polyposis, that was treated successfully by conservative management without the need for a pharmacotherapy or resection.
