Objective The prevalence of celiac disease (CD) varies geographically and ethnically; however, the prevalence among children in South China remains unknown. We therefore determined the occurrence of CD among Chinese children in South China. Methods Serum samples were collected from children and assessed for anti-tissue transglutaminase IgA antibodies (anti-tTG-IgA) and total IgA. Anti-tTG-IgA+ participants underwent human leukocyte antigen (HLA) DQ2/DQ8 determination. Samples with serum total IgA Results A total of 8794 children were enrolled, of whom 479 had chronic unexplained abdominal symptoms. Three (0.034%) children were anti-tTG-IgA+ and ten (0.114%) had serum total IgA Conclusion Our study showed a prevalence of CD autoimmunity of 0.034% and failed to identify any cases of CD, suggesting a low prevalence of CD among children in South China.

Aims: To analyze the incidence of and risk factors for post-pancreatoduodenectomy (PD) hemorrhage (PPH) and to evaluate the outcomes of reinterventions for PPH. Methods: All PDs between January 2009 and December 2014 were retrospectively evaluated. PPH was evaluated according to the criteria of the International Study Group of Pancreatic Surgery. Both univariate and multivariate analyses of risk factors for PPH and mortality were performed. Reinterventions were also evaluated. Results: Of the 1,056 PDs during the study period, 78 (7.4%) developed PPH, including 36 with grade B and 42 with grade C. Of these 78 patients, 24 (30.8%) died of PPH-related causes. Multivariate analysis showed that older age, higher total bilirubin concentration, and postoperative pancreatic fistula (POPF) were independent risk factors for PPH. Patients who died of PPH were significantly older and had lower preoperative hemoglobin and albumin concentrations than patients who did not die of PPH. Of the 78 patients with PPH, 58 underwent reintervention, including 27 who underwent angiography, 24 who underwent endoscopy, 24 who underwent re-laparotomy, and 15 who underwent more than one reintervention. Conclusions: Older age, total bilirubin, and POPF are independent risk factors for PPH. Higher mortality are associated with advanced PPH and poor nutritional conditions.

A standard nutrition screening and enteral nutrition (EN) protocol was implemented in January 2012 in a tertiary children's center in China. The aims of the present study were to evaluate the cost-effectiveness of a standard EN protocol in hospitalized patients.A retrospective chart review was performed in the gastroenterology inpatient unit. We included all inpatient children requiring EN from January 1, 2010, to December 31, 2013, with common gastrointestinal (GI) diseases. Children from January 1, 2012, to December 31, 2013, served as the standard EN treatment group, and those from January 1, 2010, to December 31, 2011, were the control EN group. Pertinent patient information was collected. We also analyzed the length of hospital stay, cost of care, and in-hospital infection rates.The standard EN treatment group received more nasojejunal tube feedings. There was a tendency for the standard EN treatment group to receive more elemental and hydrolyzed protein formulas. Implementation of a standard EN protocol significantly reduced the time to initiate EN (32.38 ± 24.50 hours vs 18.76 ± 13.53 hours; P = .011) and the time to reach a targeted calorie goal (7.42 ± 3.98 days vs 5.06 ± 3.55 days; P = .023); length of hospital stay was shortened by 3.2 days after implementation of the standard EN protocol but did not reach statistical significance. However, the shortened length of hospital stay contributed to a significant reduction in the total cost of hospital care (13,164.12 ± 6722.95 Chinese yuan [CNY] vs 9814.96 ± 4592.91 CNY; P.032).Implementation of a standard EN protocol resulted in early initiation of EN, shortened length of stay, and significantly reduced total cost of care in hospitalized children with common GI diseases.
