Ovarian teratomas are the most common germ cell neoplasm. They include mature cystic teratomas, monodermal teratomas (neural tumors, struma ovarii, carcinoid tumors) and immature teratomas. Malignant transformation of mature teratoma is very rare event and a case of sequence occurance of mature teratoma and immature teratoma in same patient is not reported yet in Korea. A 17-year-old female was found to have a huge mature teratoma of the right ovary 3 years ago. That was treated with surgery. Three years later, Immature teratoma was discovered in left ovary and treated with surgery followed by chemotherapy. We experienced one case of sequent occurrence of mature teratoma and immature teratoma on both ovary in same patient. We present it with a brief of literature.

PURPOSE: The purpose of this study was to evaluate the clinicopathological significance of responders with metastatic colorectal cancer treated with oxaliplatin chemotherapy. METHODS: A total of 52 patients with unresectable metastatic colorectal cancer were enrolled for treatment between March 2000 and August 2005. Patients received first line chemotherapy consisted of oxaliplatin 85 mg/m2 or 130 mg/m2 as a 2-hour infusion on day 1, concurrently with leucovorin (LV) 20 mg/m2 as a bolus infusion on day 1~5, followed by continuous infusion of 5-fluorouracil (5-FU) 425 mg/m2 on day 1~5. This treatment was repeated in 2 or 3 week intervals. All responses were assessed after 4 cycles of therapy by independent radiologic experts and categorized into two groups: responder (major reduction of tumor) and non-responder group (no change or progression of the tumor. RESULTS: The response rate was 51.9 percent (27/52 patients). There were no significant differences in clinicopathologic parameters between two groups. The decrease of CEA value after chemotherapy was significantly more frequent in the responder group than in the non-responder group. CONCLUSIONS: We could not find any clinical differences between the two groups, but these results suggest that oxaliplatin chemotherapy has a beneficial effect on tumor shrinkage and serum CEA value can be an indicator for tumor response of oxaliplatin in advanced colorectal cancer.

PURPOSE: Clostridium difficile (C. difficile)-associated colitis, a known complication of colon and rectal surgery, can increase perioperative morbidity and mortality, leading to increased hospital stay and costs. Several contributing factors, including advanced age, mechanical bowel preparation, and antibiotics, have been implicated in this condition. The purpose of this study was to determine the clinical features of and factors responsible for C. difficile-associated colitis after colorectal cancer surgery. METHODS: The medical records of patients who had undergone elective resection for colorectal cancer from January 2008 to April 2010 were reviewed. Cases that involved procedures such as transanal excision, stoma creation, or emergency operation were excluded from the analysis. RESULTS: Resection with primary anastomosis was performed in 219 patients with colorectal cancer. The rate of postoperative C. difficile-associated colitis was 6.8% in the entire study population. Preoperative metallic stent insertion (P = 0.017) and aged sixty and older (> or = 60, P = 0.025) were identified as risk factors for postoperative C. difficile-associated colitis. There were no significant differences in variables such as preoperative oral non-absorbable antibiotics, site of operation, operation procedure, and duration of prophylactic antibiotics. CONCLUSION: Among the potential causative factors of postoperative C. difficile-associated colitis, preoperative metallic stent insertion and aged sixty and older were identified as risk factors on the basis of our data. Strategies to prevent C. difficile infection should be carried out in patients who have undergone preoperative insertion of a metallic stent and are aged sixty and older years.

Purpose: This study evaluated the validity and reliability of Shively and colleagues’ self-efficacy for HIV disease management skills (HIVSE) among Korean participants. Methods: The original HIV-SE questionnaire, comprising 34 items, was translated into Korean using a translation and back-translation process. To enhance clarity and eliminate redundancy, the author and expert committee engaged in multiple discussions and integrated two items with similar meanings into a single item. Further, four HIV nurse experts tested content validity. Survey data were collected from 227 individuals diagnosed with HIV from five Korean hospitals. Construct validity was verified through confirmatory factor analysis. Criterion validity was evaluated using Pearson’s correlation coefficients with the new general self-efficacy scale. Internal consistency reliability and test-retest were examined for reliability. Results: The Korean version of HIV-SE (K-HIV-SE) comprises 33 items across six domains: “managing depression/mood,” “managing medications,” “managing symptoms,” “communicating with a healthcare provider,” “getting support/help,” and “managing fatigue.” The fitness of the modified model was acceptable (minimum value of the discrepancy function/degree of freedom = 2.49, root mean square error of approximation = .08, goodnessof-fit index = .76, adjusted goodness-of-fit index = .71, Tucker-Lewis index = .84, and comparative fit index = .86). The internal consistency reliability (Cronbach’s α = .91) and test-retest reliability (intraclass correlation coefficient = .73) were good. The criterion validity of the K-HIV-SE was .59 (p < .001). Conclusion This study suggests that the K-HIV-SE is useful for efficiently assessing self-efficacy for HIV disease management.

Objective: To evaluate the safety and effectiveness of the community-based cardiac rehabilitation (CBCR) program that we had developed. Methods: Individuals aged >40 years with cardiovascular disease or its risk factors who were residing in a rural area were recruited as study subjects. The CBCR program, which consisted of 10 education sessions and 20 weeks of customized exercises (twice a week), was conducted in a public health center for 22 weeks. Comprehensive outcomes including body weight, blood glucose level, and 6-minute walk distance (6MWD) were measured at baseline, 11th week, and completion. Furthermore, the outcomes of young-old (65–74 years) and old-old (≥75 years) female subjects were compared. Results: Of 31 subjects, 21 completed the program (completion rate, 67.7%). No adverse events were observed, and none of the subjects discontinued the exercise program because of chest pain, dyspnea, and increased blood pressure. Body weight and blood glucose level were significantly decreased, and 6MWD was significantly increased following program implementation (p<0.05). Both young-old and old-old women exhibited an improvement in blood glucose level and 6MWD test (p<0.05). Conclusion We reported the results of the first attempted CBCR in South Korea that was implemented without adverse events during the entire program. Improved aerobic exercise ability and reduced risk factors in all participants were observed. These improvements were also achieved by older adults aged ≥75 years.

Disseminated peritoneal leiomyomatosis is rare condition characterized by multiple subperitoneal nodules of benign smooth muscle proliferations. It is associated with high level of estrogen such as pregnancy, oral contraceptives or estrogen producing ovarian tumor, and occasionally associated with operation history of myomectomy or hysterectomy. Clinical course of disseminated peritoneal leiomyomatosis is usually benign, but malignant changes also rarely have been reported. We experienced a case of disseminated peritoneal leiomyomatosis who has history of laparoscopic myomectomy 10 years ago. The patient was a 35-year-old woman, and her chief complaint was palpable masses in lower abdomen. She underwent laparoscopic surgery which revealed numerous solid masses on the surface of peritoneum, descending colon, rectosigmoid colon, uterus, round ligament, and broad ligament. We present it with a brief review of literature.

PURPOSE: Fractional exhaled nitric oxide (FeNO) is a maker of airway inflammation, and impedance of low frequency in the impulse oscillometry system (IOS) reflects small-airway obstruction. We investigated the association of the FeNO level with IOS parameters and spirometry results in asthma patients. METHODS: Fifty-eight children with asthma (60.3%, male), mean age 8.3 years (range, 4.5-16.0 years), were enrolled in the study. Reactance and resistance at 5 Hz with IOS, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and forced expiratory flow 25%-75% of the vital capacity (FEF25%-75%) with spirometry and FeNO were measured in all patients. The Z-score of spirometry and IOS parameters and the mean level of FeNO were used for correlation and regression analysis. RESULTS: FeNO was not significantly associated with height, age, or other demographic parameters. There was a statistically significant correlation between spirometry results and IOS measurements. The FeNO level was not significantly correlated with IOS variables. After adjusting for height, sex, atopic status, and the use of inhaled corticosteroid, the FeNO level showed significant correlations with Z-score of FEV1/FVC (P=0.037, adjusted R 2=0.234). CONCLUSION: FeNO was significantly correlated with Z-scores of FEV1/FVC, but not with IOS variables. Therefore, FeNO may be used to detect whole airway obstruction, but not small-airway obstruction.

Gallbladder tuberculosis is an extremely rare disease that is rarely reported in the literature. Arriving at the correct diagnosis of gallbladder tuberculosis is difficult, and it is usually made by histopathologic examination after cholecystectomy. However, due to the low sensitivity of acid-fast stain and culture result, diagnosing gallbladder tuberculosis is still demanding even after tissue acquisition. To overcome this problem, tuberculosis-polymerase chain reaction (TB-PCR) is performed on the resected specimen, which has high sensitivity and specificity. A 70-year-old female who had previously undergone total gastrectomy for advanced gastric cancer was admitted with right upper quadrant pain. Abdominal ultrasonography and computed tomography revealed acute cholecystitis without gallstones or sludge. She underwent cholecystectomy and the histopathologic finding of the specimen showed chronic active cholecystitis without gallstones or sludge. Because she was suspected to have pulmonary tuberculosis, TB-PCR was also performed on the resected gallbladder. TB-PCR showed positive reaction for Mycobacterium tuberculosis and we could diagnose it as gallbladder tuberculosis. Herein, we present a case of gallbladder tuberculosis diagnosed by TB-PCR from resected gallbladder.

Aspiration of foreign bodies into tracheobronchial tree is more common in children than in adults. Foreign bodies in airway commonly occur by accident, and in most cases they get removed without delay. Small foreign bodies that lodge in the peripheral airway are often asymptomatic initially and can result in respiratory symptoms several years later. Although foreign body aspiration is frequently suspected in children with acute or recurrent pulmonary symptoms, it is rarely considered in adults, unless a clear history of an aspiration event can be obtained. We have experienced and studied a case of occult aspiration of a shrimp which had been lodged for a long period.

QT prolongation is a serious adverse drug effect, which is associated with an increased risk of Torsade de pointes and sudden death. Many drugs, including both cardiac and non-cardiac drugs, have been reported to cause prolongation of QT interval. Although meperidine has not been considered proarrhythmic, we present a unique case of a 16-year-old boy without an underlying cardiac disease, who developed polymorphic ventricular tachycardia, ventricular fibrillation and QT prolongation after an intravenous meperidine injection. He had no mutation in long QT syndrome genes (KCNQ1, KCNH2, and SCN5A), but single nucleotide polymorphisms were reported, including H558R in SCNA5A and K897T in KCNH2.
