Abstract
OBJECTIVES Parenteral nutrition (PN) at home is an acceptable form of delivering long-term PN for children with intestinal failure. Catheter-related bloodstream infection (CRBSI) is one of the serious complications of long-term PN and can lead to increasing morbidity and mortality. Using aseptic non-touch technique (ANTT) was proven to decrease the incidence of CRBSI in hospital patients. In this study we aimed to review the incidence of CRBSI in children receiving PN at home in our institution using the ANTT and a simplified training programme for parents and carers. METHODS We retrospectively collected clinical and microbiological data on all children with intestinal failure (IF) who were on treatment with PN at home under our specialist IF rehabilitation service between November 2012 and November 2013. RESULTS Thirty-five children were included, 16 of whom did not have any infection recorded during the study period. The overall CRBSI rate was 1.3 infections per 1000 line-days, with Staphylococcus being the commonest organism. Twenty-one children did not require catheter change and the overall catheter changes were 1.8 per 1000 line-days. CONCLUSION In this article, we report a low incidence of CRBSI in a single institution by using the principle of ANTT for accessing central venous catheters combined with a simplified, nurse-led, two-week standardised training programme for parents of children going home on PN.

Abstract
OBJECTIVES Anastomotic ulcers are a known cause of anemia in children with a history of intestinal resection. Upper endoscopy and colonoscopy can be used to diagnose these ulcers; however, the area of involvement may be difficult to visualize with standard endoscopic techniques. Capsule endoscopy (CE) offers an alternative method for visualizing the small bowel in these patients. We describe a cohort of patients with short bowel syndrome (SBS) and anemia who had anastomotic ulcers detected by CE. METHODS Retrospective chart review of patients with SBS at our institution who underwent CE for chronic gastrointestinal (GI) blood loss. RESULTS Four patients who underwent a total of 6 CE procedures were identified. The underlying diagnoses included necrotizing enterocolitis (n = 2), gastroschisis (n = 1), and jejunal atresia (n = 1). All of the patients had their ileocecal valves resected during previous surgeries and had received blood transfusions within the previous several months. The median age at the time of CE was 5.5 years (range 4-14 years). Enterocolonic anastomotic ulcers were noted in the studies as wide, flat circumferential lesions with a white base. The CE results guided a change in medical management in all of the 4 patients, including surgical revision of their anastomosis. CONCLUSIONS CE may be a helpful adjunctive tool for detecting anastomotic ulcers in patients with SBS and chronic GI blood loss.

Abstract
OBJECTIVES To describe the natural history of growth patterns and nutritional support in a cohort of infants with short bowel syndrome (SBS), and to characterize risk factors for suboptimal growth. STUDY DESIGN A retrospective chart review of 51 infants with SBS followed by our intestinal rehabilitation program. Weight and length data were converted to age, sex, and gestational age-standardized weight-for-age z-scores (WAZ) and length-for-age z-scores (LAZ). RESULTS Median (IQR) age at enrollment was 8.3 (0.9-14.6) weeks, and follow-up duration was 10 (8-13) months, including both inpatient and outpatient visits. Both WAZ and LAZ followed a U-shaped curve, with median for newborns (WAZ = -0.28; LAZ = -0.41), a nadir at age 6 months (-2.38 and -2.18), and near recovery by age 1 year (-0.72 and -0.76). Using multivariable regression analysis, diagnosis of necrotizing enterocolitis was independently associated with significant decrements of WAZ (-0.76 ± 0.32; P = .02) and LAZ (-1.24 ± 0.32; P = .0001). ≥ 2 central line-associated bloodstream infections was also independently associated with decreases in WAZ (-0.95 ± 0.33; P = .004) and LAZ (-0.86 ± 0.32; P = .007). CONCLUSION In a cohort of infants with SBS, we observed a unique pattern of somatic growth, with concomitant deceleration of both WAZ and LAZ and near recovery by 1 year. Inflammatory conditions (necrotizing enterocolitis and central line-associated bloodstream infections) represent potentially modifiable risk factors for suboptimal somatic growth.

Abstract
BACKGROUND The composition of the intestinal microbiota seems to be an important factor in determining the clinical outcome in children with short bowel syndrome (SBS). Alterations in the microbiota may result in serious complications such as small bowel bacterial overgrowth (SBBO) and intestinal mucosal inflammation that lead to prolonged parenteral nutrition (PN) dependency with subsequently increased risk of liver failure and sepsis. To date, there are no reported mappings of the intestinal microbiome in children with SBS. Here, we present the first report on the intestinal microbial community profile in children with SBS. FINDINGS The study includes children diagnosed with SBS in the neonatal period. Healthy siblings served as controls. Fecal samples were collected, and microbial profiles were analyzed by using 16S rRNA gene sequencing on the Illumina MiSeq platform. We observed a pronounced microbial dysbiosis in children with SBS on PN treatment with an increased and totally dominating relative abundance of Enterobacteriacae in four out of five children compared to children with SBS weaned from PN and healthy siblings. CONCLUSIONS The overall decreased bacterial diversity in children with SBS is consistent with intestinal microbiome mappings in inflammatory bowel diseases such as Crohn's disease and necrotizing enterocolitis in preterm infants. Our findings indicate that intestinal dysbiosis in children with SBS is associated with prolonged PN dependency.

Abstract
BACKGROUND Serial transverse enteroplasty (STEP) lengthens and tapers dilated small bowel in patients with short bowel syndrome (SBS). Previous reports document encouraging outcomes with regard to tolerance for enteral nutrition (EN) and complications appear related to the re-operative nature of many cases and to the presence of multiple staple lines. However, infectious complications following STEP have not been examined. Since infections, especially catheter-related blood stream infections (CRBSI), are considered detrimental in infants and children with SBS, we sought to define the frequency and outcomes of peri-operative infections associated with STEP. METHODS All children with SBS who underwent a STEP between 2004 and 2012 were indentified and their medical records were reviewed. Patients were considered candidates for a STEP if they had dilated small bowel and failure to advance enteral nutrition. For the purpose of this study, infections occurring within a 14-day period after STEP were considered procedure-related and were the focus of the study. RESULTS A total of 18 patients underwent 23 STEP procedures. Primary diagnoses included intestinal atresia, gastroschisis, necrotizing enterocolitis, and midgut volvulus. After the STEP, eight patients (35%) developed CRBSI, three developed wound infections, and two had urinary tract infections. Organisms isolated from either blood, wound or urine cultures included gram-positive cocci, gram-negative rods, and yeast. Perioperative antibiotics were administered in all cases with cefoxitin (43%) and piperacillin/tazobactam (30%) being most common. Neither antibiotic appeared superior in reducing the incidence of CRBSI. In three patients with persistent bacteremia despite adequate antibiotic therapy, a 74% ethanol lock resulted in negative blood cultures in all cases. Only one central venous catheter required replacement acutely for persistent fungemia. CONCLUSION STEP can improve enteral tolerance. In this fragile patient population, however, STEP carries a documented infectious burden. The optimal antibiotic prophylaxis and the role of ethanol locking in patients undergoing STEP require further study.

Abstract
Short bowel syndrome develops when the remnant mass of functioning enterocytes following massive resections cannot support growth or maintain fluid–electrolyte balance and requires parenteral nutrition. Resection itself stimulates the intestine’s inherent ability to adapt morphologically and functionally. The capacity to change is very much related to the high turnover rate of enterocytes and is mediated by several signals; these signals are mediated in large part by enteral nutrition. Early initiation of enteral feeding, close clinical monitoring, and ongoing assessment of intestinal adaptation are key to the prevention of irreversible intestinal failure. The length of the functional small bowel remnant is the most important variable affecting outcome. The major objective of intestinal rehabilitation programs is to achieve early oral nutritional autonomy while maintaining normal growth and nutrition status and minimizing total parenteral nutrition related comorbidities such as chronic progressive liver disease. Remarkable progress has been made in terms of survivability and quality of life, especially in the context of coordinated multidisciplinary programs, but much work remains to be done.

Abstract
PURPOSE OF REVIEW To critically review recent literature on small intestinal bacterial overgrowth (SIBO). RECENT FINDINGS When originally described, SIBO was added to the list of causes of the malabsorption syndrome and the pathophysiology of its consequences for the digestion and absorption of various nutrients was gradually revealed. More recently, SIBO was incriminated as a cause of diarrhea, especially in the elderly. However, the suggestion that SIBO may be a causative factor in irritable bowel syndrome and of its constituent symptoms has sparked debate and controversy on the very definition of SIBO. This debate revolves around the tests employed and the diagnostic cut-off values (for bacterial numbers) used to diagnose SIBO in clinical practice. SUMMARY A fundamental problem with SIBO, and one that allows controversy to simmer, is the lack of a universally accepted and applied gold standard for the diagnosis of SIBO. Hopefully, the application of molecular microbiological methods to the characterization of the small intestinal microbiome will tell us, once and for all, what is normal and when 'abnormality' is truly responsible for symptoms and disease. Meanwhile, therapy remains, for the most part, empirical and is based on the correction, wherever possible, of any underlying cause, attention to nutritional deficiencies, and the use of antibiotics.

Abstract
BACKGROUND The symptoms and signs of small intestinal bacterial overgrowth (SIBO) are often identical to a variety of diseases and can lead to diagnostic confusion. AIMS To review the diagnostic options for SIBO and present new investigative options for the condition. METHODS A literature search was performed on MEDLINE, EMBASE and Web of Science for English articles and abstracts. Search terms included free text words and combinations of the following terms 'small intestinal bacterial overgrowth', 'small bowel bacterial overgrowth', 'diagnostic tests', 'treatment', 'antibiotics', 'probiotics', 'metabonomics', 'proton nuclear magnetic resonance spectroscopy', 'electronic nose' and 'field asymmetric ion mobility spectrometry'. RESULTS All of the available methods to test for SIBO have inherent limitations and no 'gold-standard' diagnostic test for the condition exists. Accurate diagnosis of SIBO requires identification of bacterial species growing inappropriately within the small intestine and symptom response to antibiotics. Proton nuclear magnetic resonance spectroscopy, electronic nose technology and/or field asymmetric ion mobility spectrometry may represent better investigative options for the condition. CONCLUSIONS Novel diagnostic options are needed to supplement or replace available tests.
