AIM To investigate the role of sleep quality and psychosocial problems as predictors of functional gastrointestinal disorders(FGIDs) in doctors that work 24 hour-on-call *** In this cross-sectional observation study, using the Rome Ⅲ Questionnaire and Pittsburgh Sleep Quality Index(PSQI), we analyzed 170 doctors with 24 houron-call shifts. RESULTS Among the participants that had experienced a 24 hour-on-call shift within the last 6 mo, 48(28.2%) had FGIDs. Overall prevalence of irritable bowel syndrome(IBS) and functional dyspepsia(FD) were 16.5% and 17.1%, respectively, with 5.3% exhibiting both. Sleep scores(PSQI)(8.79 ± 2.71 vs 7.30 ± 3.43, P = 0.008), the presence of serious psychosocial alarm(83.3%vs 56.6%, P = 0.004), and the proportion of doctors who experienced over two months of recent on-call work(81.2% vs 68.9%, P = 0.044) were significantly different between individuals with or without FGIDs. Multivariate analysis revealed that presenting serious psychosocial alarm was an independent risk factor for prevalence of FD(OR = 5.47, 95%CI: 1.06-28.15, P = 0.042) and poor sleep quality(PSQI ≥ 6) was a predictor of IBS(OR = 4.17, 95%CI: 1.92-19.02, P = 0.016). CONCLUSION Physicians should recognize the role of sleep impairment and psychological stress in the development of FGIDs and a comprehensive approach should be considered to manage patients with FGIDs.

AIM: To investigate the effect of gastric acid suppressants and prokinetics on peritonitis development in peritoneal dialysis(PD) ***: This was a single-center, retrospective study. The medical records of 398 PD patients were collected from January 2000 to September 2012 and analyzed to compare patients with at least one episode of peritonitis(peritonitis group, group A) to patients who never had peritonitis(no peritonitis group, group B). All peritonitis episodes were analyzed to compare peritonitis caused by enteric organisms and peritonitis caused by non-enteric ***: Among the 120 patients who met the inclusion criteria, 61 patients had at least one episode ofperitonitis and 59 patients never experienced peritonitis. Twenty-four of 61 patients(39.3%) in group A and 15 of 59 patients(25.4%) in group B used gastric acid suppressants. Only the use of H2-blocker(H2B) was associated with an increased risk of PD-related peritonitis; the use of proton pump inhibitors, other antacids, and prokinetics was not found to be a significant risk factor for PD-related peritonitis. A total of 81 episodes of peritonitis were divided into enteric peritonitis(EP) or non-enteric peritonitis, depending on the causative organism, and gastric acid suppressants and prokinetics did not increase the risk of EP in PD ***: The use of H2B showed a trend for an increased risk of overall PD-related peritonitis, although further studies are required to clarify the effects of drugs on PD-related peritonitis.

Endoscopic findings were ulcer(82.1%), erosion(17.9%), ulcer with bleeding(24.4%), coating with drug material(5.1%), impacted pill fragments(3.8%) and stricture(2.6%). Kissing ulcers were observed in 43.6%. The main causative agents were antibiotics and non-steroidal antiinflammatory drugs. All the patients were treated with proton pump inhibitors(PPIs) or sucralfate, and the causative drugs were discontinued. Nineteen patients with drug-induced esophagitis were followed up with endoscopy and revealed normal findings, scars or healing ***: Drug-induced esophagitis mainly presents as chest pain, odynophagia and dysphagia, and may be successfully treated with PPIs and discontinuation of the causative drug.
