Paediatric eosinophilic oesophagitis in New Zealand: A 3-year prospective study.

AIM: Eosinophilic oesophagitis (EoE) is a rare, chronic, relapsing immune/antigen-mediated disease characterised by symptoms of oesophageal dysfunction, with a paucity of data among New Zealand (NZ) children. This 3-year prospective study aimed to characterise EoE diagnosed nationally and to describe initial treatment strategies adopted. METHODS: Information on new diagnoses of paediatric EoE was obtained via the New Zealand Paediatric Surveillance Unit, through monthly questionnaires. RESULTS: From February 2014 to January 2017, 73 new cases (74% male) of EoE were reported, including 74% NZ European, 10% Asian, 7% Maori, 5% Middle-Eastern and 3% Pacific peoples. Median age of symptom onset was 4 years; dysphagia (48%) was the most common, followed by vomiting/regurgitation (40%), food impaction (19%) and epigastric pain (16%). A co-morbid history of other allergic conditions was present in 62% of patients, and 41% had a first degree relative with atopy. Seventy-nine percent of patients had abnormal endoscopic findings, most commonly linear furrows and white plaques; none had strictures. Median eosinophil count per high-powered field was 40 and 50 in the mid and distal oesophagus, respectively. Fifty-four percent of patients were initially managed with dietary manipulation alone (four required elemental feeds, five nasogastric tubes). Fifty-four percent of patients were treated with swallowed corticosteroids and 7% with prednisone. One patient was also treated with a leukotriene receptor antagonist. CONCLUSION: This first prospective study on paediatric patients with EoE in NZ finds similar demographics and disease characteristics as in other populations despite our unique ethnic population. Long-term prospective observational data should significantly improve our knowledge of this rare condition.

Gastric emptying in children with type 1 diabetes mellitus: A pilot study.

AIM: Delayed gastric emptying (GE) has been demonstrated in adults with type 1 diabetes mellitus (T1DM). Little is known about GE in children with T1DM. Most methods to measure GE are invasive, that is, scintigraphy, or are only indirectly related to GE, that is, electrogastrography. Carbon-13 breath testing is a non-invasive, very low-risk procedure that accurately correlates with GE time. This was a pilot study to determine the feasibility of using carbon-13 breath testing to measure GE in children with T1DM and healthy controls. METHODS: Cases were recruited from children aged 7-15 years presenting to the paediatric diabetic clinic at Christchurch Hospital. Controls were peers of the cases. Children with known gastrointestinal disease were excluded. After an overnight fast, each child ate a standardised pancake labelled with carbon-13 sodium octanoate. Samples of breath were collected over a 4-h period. Samples were analysed by mass spectrometry. GE half time (GET1/2 ) and GE coefficients (GEC) were calculated by linear regression to obtain a measure of GE. RESULTS: A total of 19 cases and 15 age- and gender-matched controls underwent testing. The mean GEC in the cases was 3.19 (±0.38) and 2.90 (±0.29) in controls (P = 0.03), with an effect size = 0.86. Mean GET1/2 in the cases was 99 (52.1) min and 103 (27.5) in controls (P = 0.8), with an effect size = 0.1. CONCLUSION: The study generated results suggesting that a larger study will be worthwhile to investigate the relationship between GE and T1DM.

Looking for coeliac disease in children with type 1 diabetes mellitus.

AIM: To establish how clinicians in New Zealand (NZ) approach screening for and management of coeliac disease (CD) in type 1 diabetes mellitus (T1DM) in their paediatric patients. METHODS: All clinicians caring for children under 15 years with T1DM in NZ in 2010 were asked to complete an online survey detailing their personal and departmental approach to diagnosing and managing patients with CD and T1DM. RESULTS: Thirty-four from 37 clinicians responded to the survey. Most clinicians in NZ have a protocol for screening for CD in T1DM, and 25/34 respondents will screen for CD at diagnosis of T1DM. Those who do not screen will use symptoms, growth and hypoglycaemia as indicators to test. All use anti-tissue transglutaminase to screen for CD, and 32/34 use biopsy-proven CD as a criterion for commencing gluten-free diet (GFD). Nearly all consultants will still advise a GFD in symptom-free CD and will try to encourage the patients to adopt a GFD if they initially decline. CONCLUSIONS: Most clinicians in NZ screen for CD, but there is a wide variation in practice.

A questionnaire-based assessment of gastrointestinal symptoms in children with type 1 diabetes mellitus.

BACKGROUND: Children commonly report gastrointestinal symptoms. Limited evidence suggests that children with type 1 diabetes mellitus (T1DM) report more gastrointestinal symptoms than healthy children without diabetes. The aim of this study was to ascertain the pattern and severity gastrointestinal symptoms reported by children with diabetes and healthy children without diabetes. METHODS: After recruitment, children (less than 16 years of age) with type 1 diabetes and healthy control children reported their recent gastrointestinal symptoms using a short questionnaire. A five-point Likert scale was utilised to grade the severity of each symptom and an overall symptom score for each child was derived. RESULTS: One hundred and fifty cases (88% of eligible population) and 94 controls completed the questionnaire. Both groups had similarly high rates of any gastrointestinal symptom [80% of controls vs. 85% cases, OR 1.5 (95% CI: 0.7-3.1)]. Children with diabetes had higher mean scores for abdominal pain (1.3 vs. 1.0, P=0.02) and reflux (0.4 vs. 0.20, P=0.02). Cases also had a higher overall mean score than controls (4.9 vs. 3.4, P=0.02). CONCLUSIONS: Overall, gastrointestinal symptoms were reported at the same frequency by both groups of children. However, the children with diabetes had more severe symptoms, especially those of reflux and abdominal pain. The reasons for these differences remain to be elucidated.

Transition clinics: an observational study of themes important to young people with inflammatory bowel disease.

BACKGROUND: Transition from paediatric to adult services can be stressful and potentially disruptive for adolescents diagnosed with inflammatory bowel disease (IBD). This study aimed to ascertain transition-related factors relevant to young people in New Zealand. METHODS: Adolescents diagnosed with IBD prior to their 16th birthday were asked to participate in focus groups to generate transition-related themes. These themes were used to develop a questionnaire, which was then administered to a second group of young patients. RESULTS: Initial focus groups discussions generated several key themes: these included concerns about meeting new people in unfamiliar surroundings, the importance of shared clinics and assessments for transition readiness. The subsequent transition questionnaire was completed by 53 young people (28 female and 48 with Crohn's disease). The most commonly reported difficulty by those entering transition was meeting a new doctor. This and building a new relationship/trust were the main concerns of respondents who were preparing for or within a transition process. Parental assessment of illness and readiness to transition were not thought to be as important as other factors for determining readiness for transition. The character of their new adult gastroenterologist was the factor felt most likely to make transition easy. CONCLUSIONS: The main concerns of these young patients with IBD, at various stages of transition, were about meeting a new team and building new relationships. Planning and conducting a structured transition process should consider these factors to optimise the process.

Effectiveness of the surgical safety checklist in correcting errors: a literature review applying Reason's Swiss cheese model.

Approximately 2,700 patients are harmed by wrong-site surgery each year. The World Health Organization created the surgical safety checklist to reduce the incidence of wrong-site surgery. A project team conducted a narrative review of the literature to determine the effectiveness of the surgical safety checklist in correcting and preventing errors in the OR. Team members used Swiss cheese model of error by Reason to analyze the findings. Analysis of results indicated the effectiveness of the surgical checklist in reducing the incidence of wrong-site surgeries and other medical errors; however, checklists alone will not prevent all errors. Successful implementation requires perioperative stakeholders to understand the nature of errors, recognize the complex dynamic between systems and individuals, and create a just culture that encourages a shared vision of patient safety.
