Since the first clinical observation by Kelly and MacCallum, gas-forming infection of the urinary tract has been extensively studied. It is characterized by gas production within the urinary tract. The gas may often pass outside the urinary tract. Patients with this disorder invariably have uncontrolled diabetes mellitus and pos sibly associated obstructive uropathy. It is usually caused by aerobic bacteria, most commonly Escherichia coli. In the literature, the majority of cases were emphy sematous pyelonephritis alone or emphysematous cystitis separately. Bilateral renal involvement associated with emphysematous cystitis is very rarely seen and no case was reported yet in Korea. We report a case of bilateral emphysematous pye lonephritis and emphysematous cystitis which occured in 48-year-old diabetic patient simultaneously. It was caused by E. coli. The patient was cured by medical management alone.

Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by the calcification and ossification of soft tissue, and can lead to severe cervical kyphosis, presenting with a spectrum of physical complaints including dysphagia, hoarseness, stridor, aspiration pneumonia, and dyspnea due to airway compromise. Restrictive ventilatory impairment is very rare. We encountered a 73-year-old man with DISH presenting with progressive dysphagia and dyspnea over a few months. The symptoms were evaluated with a video fluoroscopy swallowing study and pulmonary function tests (PFT). The PFT revealed restrictive ventilatory impairment. A neck magnetic resonance imaging (MRI) study showed anterior cervical osteophytes causing upper airway compromise and compression of the esophagus. Osteophytes were removed surgically and the patient improved clinically. Here, we describe the case with a literature review.

A 59-year-old woman was transferred to our institution with a diagnosis of acute type A aortic dissection. During aortic replacement surgery, the dissection had not extended to the orifice of the left coronary artery. However, ST segment elevation was observed on an electrocardiogram monitor immediately postoperatively. An emergent coronary angiogram showed almost complete collapse of the lumen of the left coronary artery due to pulsatile compression of the false lumen, which was caused by extension of the aortic dissection. Percutaneous coronary intervention (PCI) was performed with placement of stents in the left anterior descending artery (LAD) and left circumflex artery. Coronary angiography and intravascular ultrasound performed 45-days after PCI showed significant instent restenosis (ISR) at the proximal portion of the LAD and residual coronary artery dissection of the diagonal branch. Repeat balloon angioplasty was performed at the site of the ISR. A follow-up coronary angiogram 8-months after the PCI showed no evidence of ISR.

PURPOSE: Preoperative chemoradiotherapy has become an important adjunct in the management of rectal cancer. But both systemic toxicity of chemotherapy and local effect of radiation interfere wound healing of intestinal anastomosis and ultimately may lead to anastomotic leak and septic complications. The purpose of this study is to determine the optimal time interval between preoperative chemoradiotherapy and anastmotic construction, and it was evaluated by security of anastomotic construction. METHODS: One hundred and twenty male Sprague Dawley rats weighing approximately 250 g were randomly divided into 4 groups (Control group; n=40, Group 1; n=20, Group 2; n=20, Group 3; n=40). The control group (n=20) underwent anastomotic construction at 1 week after general anesthesia without preoperative chemoradiotherapy. The experimental animals (group 1, 2, 3) received preoperative chemoradiotherapy with 5 daily dose (20 mg/kg) of 5-fluorouracil and single dose of 1500 cGy radiation at the rectosigmoid junction under general anesthesia on the day after last dose of chemotherapy. And group 1~3 subsequently underwent a laparotomy to make anastomotic construction at 1 week (Group 1), 2 weeks (Group 2), and 3 weeks (Group 3; n=20) after completion of chemoradiotherapy. The security of anastomotic construction was determined by bursting pressure, tissue hydroxyproline content, gross and microscopic findings of anastomotic area at the 5th and 10th postoperative day after anastomotic construction. To evaluate systemic toxicity after che-moradiotherapy, serial body weight and alteration of CBC were measured in the control group (n=20) and Group 3 (n=20) without anastomotic construction. RESULTS: At the 5th postoperative day, Mean bursting pressures of the all treated groups were lower than that of the control group (Control group; 88 23 mmHg, Group 1; 49 22 mmHg, Group 2; 56 17 mmHg, Group 3; 78 23 mmHg). The difference was not significant in the group 3 compared with the control group. Body weight decreased in the all treated animals. The mean body weight was lowest on the day 8 after completion of chemoradiotherapy and then it gradually increased. WBC and platelet counts also decreased in the all treated animals. WBC count was lowest on the day 1 and platelet count was lowest on the day 3 after completion of chemoradiotherapy. Mean hydroxyproline contents at the anastomotic sites in the all treated groups were higher than that of the control group, especially in the group 2 and 3. Similar histologic changes were observed in both group 3 and control group. CONCLUSION: The results suggest that the optimal time interval for safe intestinal anastomosis after preoperative chemoradiotherapy is 3 weeks or later.

BACKGROUND/AIMS: The Internet is the main resource for health-related information. The incidence of inflammatory bowel disease (IBD) is rapidly increasing in Asian countries. However, the quality of websites for IBD available in this region has not been evaluated. We aimed to evaluate the quality of the information on IBD obtained from Korean websites. METHODS: Using the terms “Crohn’s disease” or “ulcerative colitis,” websites were selected from those obtained with the three most renowned search engines in Korea; 60 websites from the results of each engine were chosen. The websites were classified into institutional, commercial, charitable, supportive, or alternative medicine types according to the characteristics of each site. The websites were evaluated regarding content quality using the validated DISCERN instrument and the Journal of the American Medical Association benchmarks. RESULTS: The median score of all the websites according to the DISCERN instrument was 32 (interquartile range, 25 to 47) out of 80, indicating an insufficient overall quality of information. The alternative medicine sites scored the lowest, whereas the institutional sites scored the highest (p < 0.05). The quality of information was significantly different among the search engines (p = 0.028). The rank of appearance in the Google search result did not correlate with the quality level of the information. CONCLUSIONS The quality of information on the Internet regarding IBD varied according to the website type and search engine. Accreditation and quality assurance systems should be implemented for websites to ensure that the public and patients obtain accurate information on IBD.
