Emphysematous pyelonephritis is rare but freuently fatal complication of renal parenchymal infection, mostcommonly occurs in diabetic patients and is often associated with urinary obstruction, prior urologicalabnormality or infection. From 1898 to 1984 , about 50 cases of empysematous pyelonephritis have been reporteduniversally. The diaignosis of emphysematous pyelonephritis can be made only roentgenographically. In the last 2years, we have had two cases of emphysematous pyelonephritis at our hospital. It is our purpose to report twopatients who have survived wtih a brief review of the previous literature.

We experienced two cases of occupational asthma induced by Elk dander in Elk-feeders and confirmed these cases by the bronchial provocation test with Elk dander. Both of them showed dual asthmatic response. They also showed positive reaction to the skin prick test with EIK dander. Now one of them has no asthmatic symptoms at all after complete avoidnce of EIK dander.

Percutaneous antegrade pyelography guided by ultrasonography and fluoroscopy was attempted in 25 patients with supravesical obstructive hydronephrosis and suctessful in 23 patients to evaluate the site and nature of urinary obstruction. The etiology of the obstructive uropathies were urinary stricture in 11 cases,urinary Tbc. in 5 cases, urinary stone in 3 cases, uterine prolapse with cystocele, pyonephrosis, ureteral metastatic testicular carcinoma in 1 case respectively. No significant complication of the percutaneous antegrade pyelography was observed. Percutaneous antegrade pyelography provides significant diagnostic informations on the obstructive lesion and can be accomplished with ease and safe in patients with obstructiv hydronephnosis as a diagnostic procedure of choice in infants and children or as an alternative to a retrograde pyelography.

We experienced two cases of Boerhaave syndrome (spontaneous esophageal rupture). The first patient was a 62-year-old male who presented epigastric pain after several violent vomitings associated with alcohol ingestion. Diagnosis was done early and promptly in our emergency center and then definitive treatment was done only after 12hrs from onset of his symptom and he was discharged in relatively good condition 256ays after his admission. The second patient was a 44-year-old male who was transfered to our emergency center with chest pain, dyspnea and fever after vomitings associated with autobicycle accident. Diagnosis was delayed due to initial trauma oriented evaluation and incidious develpement of typical clinical findings and then he was managed conservatively but he died of multiple organ failure due to sepsis. We report these cases with literature review.

BACKGROUND/AIMS: After colorectal cancer surgery, colonoscopic surveillance should be done for prevention and early detection of secondary cancer. This study aimed to identify the group with high risk of developing colorectal adenoma after curative surgery of colorectal cancer. METHODS: We retrospectively investigated the medical records of the subjects of 130 patients who had been examined using colonoscopy before and after the curative surgery. RESULTS: The average age was 59.4 years. Synchronous adenomas were in 42 patients (32.3%). The occurrence rate was significantly high in men (38.8%) than women (22.0%). After the operation, the mean interval of examining colonoscopy was 11.6 months (3-24 months) and metachronous adenomas were detected in 26 patients (20.0%). The patients who have both metachronous and synchronous adenomas were observed in 13/42 (30.9%) and the patients of metachronous adenomas without synchronous adenomas were observed in 13/88 (14.8%). The occurrence rate of metachronous adenomas with synchronous adenomas was significantly high. The frequency of synchronous adenomas didn't increase with age. However, the frequency of metachronous adenomas increased with age: 0/9 (0%) under 40 years, 7/49 (14.3%) in 41-61 years and 19/72 (26.4%) over 61 years. The occurrence rate was higher in men (26.3%) than women (10.0%). CONCLUSIONS: The occurrence rate of metachronous adenomas after colorectal cancer surgery was higher in the patients with synchronous adenomas, male gender and old aged patients.

BACKGROUND/AIMS: Neuropepetide Y (NPY) is involved in the regulation of several gut functions, but the neuronal action of NPY has not been fully investigated. This study was designed to investigate the effect and mechanism of action of NPY on motility in the proximal and distal rat colon. METHODS: Rat colon with an intact superior mesenteric artery was isolated. After a basal period, NPY was administered at concentrations of 14 pM, 70 pM, 140 pM, and 280 pM. Intraluminal pressures were monitored in the proximal and distal colon. The contractile response was expressed as a percent change of motility indices over the basal level. After a pre-infusion of atropine (AT), tetrodotoxin (TTX), propranolol, hexamethonium, and phentolamine, NPY was infused at a concentration of 140 pM, and pressures were monitored. RESULTS: NPY increased the colonic motility at concentrations of 14, 70, 140, and 280 pM in the proximal colon (28.5+/-28.2%, 48.4+/-34.3%, 122.9+/-97.3%, 68.2+/-28.1%, respectively) and in the distal colon (44.9+/-25.9%, 103.8+/-72.0%, 237.1+/-131.0%, 93.0+/-63.9%, respectively) in a dose-dependent manner. The enhancing effect of NPY (140 pM) on colonic motility was significantly suppressed by pretreatment with atropine, propranolol, and TTX. However, the effect of NPY was not inhibited by hexamethonium or phentolamine. CONCLUSION: NPY increases colonic motility. The enhancing effect of NPY on colonic motility may require cholinergic input via muscarinic receptors or adrenergic input via beta-receptors.

BACKGROUND/AIMS: The aim of this study was to evaluate the characteristics of cryptogenic and biliary pyogenic liver abscess by comparing the clinical aspects between the two groups. METHODS: Of 119 patients treated for pyogenic liver abscess from 2000 to 2004, 82 subjects with cryptogenic liver abscess and 21 with biliary abscess were analysed retrospectively. RESULTS: There were no significant differences between the two groups regarding clinical symptoms. The characteristics of abscess were similar except the size of abscess. The size of abscess less than 5 cm in diameter was more common in billiary group than in cryptogenic group (p=0.004). Compare to cryptogenic group, biliary group had more positive culture test from abscess (100% vs. 69%, p=0.006). Especially, E. coli isolated from abscess culture (28% vs. 7%, p=0.014) and blood culcure (23% vs. 4%, p=0.035) were more common in biliary group than in cryptogenic group. There was no difference in mortality between the two groups (biliary vs. cryptogenic: 4.8% vs. 0%, p=0.204). However, the rate of clinical improvement was higher in cryptogenic group than in biliary group (92.7% vs. 66.7%, p=0.001). CONCLUSIONS: Biliary liver abscess had similar clinical characteristics to cryptogenic origin. Biliary liver abscess had smaller abscess size and more positive abscess culture rates than cryptogenic abscess. Improvement rate without complication and recurrence was higher in cryptogenic group than biliary group.

Gastric volvulus is an uncommon condition which is difficult to diagnose and treat. It designates abnormal rotation of the stomach along its longitudinal (organoaxial) or transverse (mesenteroaxial) axis. When the rotation exceeds 180 degrees, gastric obstruction or strangulation may occur. The classical presentation of acute gastric volvulus is the triad of severe epigastric pain, vomiting followed by retching without the ability to vomit, and difficulty or inability to pass a nasogastric tube. Delay in diagnosis and treatment of gastric volvulus can lead to fatal complications such as gastric ischemia, perforation, and hemorrhage. Gastric volvulus is a true emergency which should be treated immediately either surgically or by upper endoscopy. We report a case of an acute incarcerated gastric volvulus due to a left-sided diaphragmatic hernia in an adult male patient, which was treated successfully by operation.

PURPOSE: We retrospectively analyzed the patients who received curative radiotherapy for unresectable stage III NSCLC to investigate the impact of chemotherapy. MATERIALS AND METHODS: From 1998 to 2001, the records of 224 patients who completed curative radiotherapy for NSCLC were reviewed. There were 210 males and 14 females, and their median age was 64 years (range 38 ~83). 54 patients had stage IIIA disease and 170 patients had stage IIIB disease. Conventional radiotherapy was given and the radiation dose ranged from 50~70 Gy with a median of 60 Gy, and chemotherapy was combined for 116 patients (52%). RESULTS: The median survival, the 2-year, and 5-year actuarial survival rates of all 224 patients were 15 months, 30%, and 7%, respectively. The median survival of the patients with stage IIIA and IIIB disease were 21 months and 13 months, respectively (p=0.14). The median survival of patients who received chemoradiation was 18 months compared to 14 months for the patients who received RT alone (p=0.02). Among the chemoradiation group of patients, the median survival time of the patients who received 1 to 3 cycles of chemotherapy was 16 months and that for the patients who received more than 3 cycles was 22 months (p=0.07). We evaluated the effects of the timing of chemoradiation in 57 patients who received more than 3 cycles of chemotherapy. The median survival of the patients with the concurrent sequence was 25 months and that for the patients with the sequential chemotherapy was 19 months (p=0.81). CONCLUSIONS: For advanced stage III non-small cell lung cancer patients who completed the curative radiotherapy, the addition of chemotherapy improved the survival compared to the patients who received radiotherapy alone.

Ethylene glycol is a sweet-tasting liquid with industrial use as a solvent or as a starting reagent in chemical processes. Physicians are familiar with ethylene glycol because it is the major component of many antifreeze solutions and is taken in suicide attempts or, more often inadvertency. its metabolites may cause severe intoxication. Unfortunately, its metabolites are highly toxic and require rapid treatment Treatment involves correction of metabolic acidosis, ethanol administration and enhancement of elimination. The most commonly used elimination technique is hemodialysis We describe an 21-year-old man with acute renal failure due to ingestion of antifreeze that contained ethylene glycol. He was transferred to our hospital because of aggressive management The recovery of our patient with severe ethylene glycol intoxication illustrates that aggressive and early treatment can prevent mortality and morbidity.
