Unlike simple forward-viewing endoscopes such as gastroscope or colonoscope, duodenoscope houses much more complex design to fulfil its function. This design differences leave duodenoscopes more prone to contamination from inadequate disinfection process and potential dissemination of pathogens. Recent reports on dissemination of infection through the duodenoscope mandated an overhaul of duodenoscope utilization including development of a disposable duodenoscope. This article reviews the current state of disposable duodenoscope development, including reported early efficacy as well as its future direction and utilization.

The purpose of this study was to develop a brief rating scale of post-traumatic stress disorder (PTSD) symptoms among sexual violence victims. We analyzed the data from 195 victims and 220 non-victims to select meaningful items from the original PTSD rating scales. We also examined the validity of the brief scale by assessing internal consistency and ROC curves. The optimal cutoff scores for each brief scales were obtained. The results showed that a different approach may be required for early intervention in different age groups.

Topiramate is an antiepileptic drug widely used to treat various seizures, mood disorders and migraine based on its various pharmacological mechanisms. Even though nephrolithiasis is listed as one of its side effects, there have been no cases reporting nephrolithiasis caused by use of topiramate on Korean pediatric patients. Since the use of topiramate is increasing in many patients, the possibility of nephrolithiasis after the treatment needs to be considered. Here, we report our experience in correcting neprholithiasis by simply discontinuing topiramate without administering any additional treatments.

Sclerosing ecapsulating peritonitis (SEP) first described by Gandhi and Humyn at 1980 is generally recognized, but uncommon complication of continous ambulatory peritoneal dialysis (CAPD) and the prognosis is very poor. A 62-year old female was admitted to our hospital with chief complaint of abdominal pain, nausea, vomiting. On physical examination, abdominal pain was not detected. Abdominal CT demonstrated paralytic ileus and adhesion in proximal ileum. She underwent adhesilolysis of ileum and repair of perforated ileum. We experienced one case of SEP presenting small bowel perforation and peritonitis in patient with IPD. We report this case with review of the literature.

Background: Consistent uptake of colorectal cancer (CRC) screening is important to reduce the incidence and mortality from advanced-stage CRC and increase the survival rate of the patients. We conducted a longitudinal study to determine the factors affecting CRC screening compliance in Korean adults using individual-level linked data from the Korean National Health and Nutrition Examination Survey, Korean National Health Insurance Service, and Korean Health Insurance Review and Assessment Service. Methods: We selected 3,464 adults aged 50–79 years as the study population and followed them for 12 years (January 2007–December 2018). The outcome variable was the level of adherence to CRC screening, categorized as nonadherent, intermittently adherent, and consistently adherent. An ordinal logistic regression model was designed to determine the socioeconomic factors, family history of CRC, and medical conditions that could facilitate the consistent uptake of CRC screening. Results: The results showed a significant and positive association between consistent uptake of CRC screening and the 100–150% income category (odds ratio [OR], 1.710; 95% confidence interval [CI], 1.401–2.088); clerical, sales and service job category (OR, 1.962; 95% CI, 1.582–2.433); residency at medium-sized cities (OR, 1.295; 95% CI, 1.094–1.532); high-school graduation (OR, 1.440; 95% CI, 1.210–1.713); married status (OR, 2.281; 95% CI, 1.946–2.674); use of employment-based national health insurance (OR, 1.820; 95% CI, 1.261–2.626); use of private insurance (OR, 2.259; 95% CI, 1.970–2.589); no disability (OR, 1.428; 95% CI, 1.175–1.737); family history of CRC (OR, 2.027; 95% CI, 1.514–2.714); and history of colorectal neoplasm (OR, 1.216; 95% CI; 1.039–1.422). Conclusion The lack of regular participation in CRC screening programs in the Republic of Korea was found to be an issue that requires attention. Policies on CRC screening must place increased emphasis on strengthening educational and public relations initiatives.
