BACKGROUND/AIMS: Gastric mucus should be removed before endoscopic examination to increase visibility. In this study, the effectiveness of premedication with pronase for improving visibility during endoscopy was investigated. METHODS: From April 2010 to February 2011, 400 outpatients were randomly assigned to receive endoscopy with one of four premedications as follows: dimethylpolysiloxane (DMPS), pronase and sodium bicarbonate with 10 minutes premedication time (group A, n=100), DMPS and sodium bicarbonate with 10 minutes premedication time (group B, n=100), DMPS, pronase and sodium bicarbonate with 20 minutes premedication time (group C, n=100), and DMPS and sodium bicarbonate with 20 minute premedication time (group D, n=100). One endoscopist, who was unaware of the premedication types, calculated the visibility scores (range, 1 to 3) of the antrum, lower gastric body, upper gastric body and fundus. The sum of the scores from the four locations was defined as the total visibility score. RESULTS: Group C showed significantly lower scores than other groups (p=0.002). Group C also had the lowest frequency of flushing, which was significantly lower than that of group D. Groups C and D had significantly shorter durations of examination than groups A and B. CONCLUSIONS: Using pronase 20 minutes before endoscopy significantly improved endoscopic visualization and decreased the frequency of water flushing.

Differential diagnosis of invasive aspergillosis from other pulmonary fungal infections including mucormycosis is important because the treatment is pathogen-dependent. Clinically, invasive aspergillosis is often discriminated from other mold infections on the basis of typical histopathologic features in the biopsy specimen. However, biopsy alone is not always complete because different fungal species can display similar histopathologic features. Surrogate markers or molecular-based assays can be useful when the results of conventional diagnostic modalities are conflicting. Here, we present a case of invasive pulmonary aspergillosis histologically mimicking mucormycosis, which was confirmed by fungal polymerase chain reaction.

OBJECTIVE: To evaluate the retrieval rate and accuracy of ultrasound (US)-guided 14-G semi-automated core needle biopsy (CNB) for microcalcifications in the breast. MATERIALS AND METHODS: US-guided 14-G semi-automated CNB procedures and specimen radiography were performed for 33 cases of suspicious microcalcifications apparent on sonography. The accuracy of 14-G semi-automated CNB and radiology-pathology concordance were analyzed and the microcalcification characteristics between groups with successful and failed retrieval were compared. RESULTS: Thirty lesions were successfully retrieved and the microcalcification retrieval rate was 90.9% (30/33). Thirty lesions were successfully retrieved. Twenty five were finally diagnosed as malignant (10 invasive ductal carcinoma, 15 ductal carcinoma in situ [DCIS]) and five as benign. After surgery and mammographic follow-up, the 25 malignant lesions comprised 12 invasive ductal carcinoma and 13 DCIS. Three lesions in the failed retrieval group (one DCIS and two benign) were finally diagnosed as two DCIS and one benign after surgery. The accuracy of 14-G semi-automated CNB was 90.9% (30/33) because of two DCIS underestimates and one false-negative diagnosis. The discordance rate was significantly higher in the failed retrieval group than in the successful retrieval group (66.7% vs. 6.7%; p < 0.05). Punctate calcifications were significantly more common in the failed retrieval group than in the successful retrieval group (66.7% vs. 3.7%; p < 0.05). CONCLUSION: US-guided 14-G semi-automated CNB could be a useful procedure for suspicious microcalcifications in the breast those are apparent on sonography.

Coronary arteriovenous fistula (CAF) is most common form of hemodynamically significant coronary anomaly. CAF combined with atrial septal defect (ASD), however, constitutes an uncommon subgroup of CAF. We present a case of congenital CAF combined with secondum ASD, which are manifested by congestive heart failure. These anomalies were identified by transthoracic echocardiography and coronary angiography respectively. These ASD and CAF were closed by operation successfully without any complication.

Calyptella capula is reported for the first time in Korea. It was found in spring in Chungcheongbuk-do, central Korea, growing in a dead stalk of Sesamum indicum. A description and molecular phylogenetic analyses are reported.

BACKGROUND/AIMS: Irritable bowel syndrome (IBS) is prevalent in general population. This study investigates the prevalence of IBS in medical college students in Korea as well as the influence of dietary habits and nutritional intake on IBS. METHODS: This study is a cross-sectional study of 319 students (239 males and 80 females, age 22.3 +/- 2.5 years) from the 6 grade levels of the Medical College in Korea. All students filled out a self-reported questionnaire for ROME III criteria. They also completed a questionnaire to validate dietary habits and food frequency in Korean. RESULTS: The overall prevalence of IBS was 29.2% without correlation to age, body mass index and grade level in Medical School. However, the prevalence was significantly higher in females than males (33/80 vs 60/239, P = 0.007). There were no significant differences between the IBS-group and the non-IBS group in aspect of nutrition. Not only the diet habits, but also the daily nutritional intake, and even the breakdown into the 12 micronutrients, yielded no significant differences between the 2 groups. CONCLUSIONS: Twenty-nine percent of the medical college students have IBS with a greater prevalence in females. The dietary habits and nutritional intake of the students might not be associated with IBS.
