BACKGROUND/AIMS: Clostridium difficile is an important cause of diarrhea in hospitalized patients. C. difficile-associated diarrhea (CDAD) is usually diagnosed following a stool test for C. difficile cytotoxin or stool culture for the presence of toxigenic C. difficile. However, the reported sensitivities of these tests are variable. Sigmoidoscopy may be an effective diagnostic method in patients with a false-negative stool test for cytotoxin. This study examined the role of flexible sigmoidoscopy in the diagnosis of CDAD. METHODS: Among the patients who had diarrhea and were examined with sigmoidoscopy in Eulji University Hospital between January 2005 and July 2008, 102 patients suspected of having antibiotic-associated diarrhea (AAD) based on their clinical symptoms were enrolled. Of the 102 patients, 74 were diagnosed with CDAD based on C. difficile cytotoxin or sigmoidoscopic findings of pseudomembranous colitis. The medical records of these 74 patients were reviewed retrospectively. RESULTS: Of the 74 patients, sigmoidoscopic findings revealed a pseudomembrane in 63 patients (85.1%) and colitis in nine (12.2%), while two patients (2.7%) appeared normal. Of the 63 patients with pseudomembranous colitis at sigmoidoscopy, the stool C. difficile cytotoxin assay was negative in 27 (42.9%). CONCLUSIONS: Flexible sigmoidoscopy was highly sensitive in pseudomembranous colitis and is useful in diagnosing patients with a delayed or negative stool test for C. difficile cytotoxin. Therefore, we recommend flexible sigmoidoscopy in patients suspected of having C. difficile-associated diarrhea for the diagnosis of CDAD.

BACKGROUND: Thoracic paravertebral blockade (TPVB) can be effective in many clinical settings. However, many clinicians are reluctant to use this technique due to its adverse effects such as pneumothorax. The aim of this study was estimate the appropriate depth and width for safe needle positioning. METHODS: The depth from skin to the paravertebral space (PVS) and the width from the spinous process (SP) to the PVS and the lateral tip of the transverse process (LTTP) were measured in all available sections from 84 patients examined by chest computed tomography (CT). The correlation between age, gender, body mass index (BMI) and each measured value was analyzed. RESULTS: All 828 sections from the 84 patients aged between 19 and 65 years old were evaluated. The minimum and maximum values of the mean depth from the skin to PVS were 40.3-52.4 mm in men and 41.2-55.9 mm in women. The minimum and maximum values of the mean width from the SP to LTTP were 29.2-34.6 mm in men and 23.7-31.0 mm in women. At every thoracic level, the depth to PVS was similar in both genders but the width from the SP to the NEP in men was significantly higher than in women. Weight significantly influenced the width from the SP to LTTP in men but height and BMI did not. Also weight and BMI significantly influenced the depth from skin to PVS in almost all of the thoracic region at both sex, but height did not influence the depth from skin to PVS in both sex. CONCLUSIONS: We report clinically useful estimates that may be used to help avoid side effects such as pneumothorax and achieve a successful thoracic paravertebral blockade.

Ulcerative colitis is associated with various extraintestinal manifestations. Skin lesions can occur in 9-19% of patients with ulcerative colitis. Pyoderma gangrenosum is the most severe dermatologic complication that is associated with ulcerative colitis. It is a painful, chronic ulcerating skin disease of unknown cause. The lesions usually appear on the pretibial area, but may also be found elsewhere. Diagnosis is clinical as there are no accepted histological diagnostic criteria. Systemic steroid therapy remains the treatment of choice in most patients, but various other agents have been used with occasional success including topical antibiotics, cyclosporine and infliximab. We experienced a case of pyoderma gangrenosum that developed on both pretibial areas in a 41-year-old female patient with active ulcerative colitis. The patient was treated with a corticosteroid and sulfasalazine. We report this case with a review of the literature.

BACKGROUND/AIMS: Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography (ERCP). Only a few pharmacologic agents have been shown to have potential efficacy for the prophylactic treatment of post-ERCP pancreatitis (PEP). The aim of this study was to determine whether prophylactic gabexate and ulinastatin can decrease the incidence of PEP. METHODS: From January 2005 to April 2010, 1,679 patients undergoing ERCP treatment were consecutively enrolled in the study. After selective exclusion, a total of 1,480 patients were included in the analysis. The patients were separated into 3 groups according to the prophylactic administration of gabexate (593 patients), ulinastatin (229 patients), or saline solution (658 patients) and analyzed retrospectively. The primary outcome measurements were the incidence of pancreatitis and hyperamylasemia. RESULTS: PEP occurred in 21 of the 593 (3.5%) patients who received gabexate, 16 of the 229 (7.0%) patients who received ulinastatin, and 48 of the 658 (7.3%) patients who received a saline solution. The incidence of PEP was significantly different between the gabexate and ulinastatin or saline solution groups (p<0.05). CONCLUSIONS: Gabexate prophylaxis is effective in preventing PEP. However, there is no difference in the beneficial effects of the prophylactic administration of ulinastatin and a saline solution.
