Diet plays a key role in the manifestation and severity of gastrointestinal symptoms, with increasing research interest on the role of diet in small bowel disorders. There are predominantly 3 small bowel conditions that have potential dietary interventions. Self-reported nonceliac gluten/wheat sensitivity is prevalent. Although gluten is believed to be a potential trigger for symptoms, other components of wheat may also be triggers, including fructans, alpha-amylase trypsin inhibitors, and wheat germ agglutinins. The diagnosis can be challenging, given the lack of validated biomarkers. A gluten-free diet that excludes the abovementioned triggers is the cornerstone of treatment; however, unlike celiac disease, there is uncertainty about the level of adherence or whether the gluten-free diet is a lifelong intervention. Several primary gastrointestinal disorders are associated with an increase in inflammatory cells including eosinophils. Diet seems to be an important driver of disease pathogenesis in eosinophilic gastroenteritis, with elimination and elemental diets showing promise in management, with further robust trials required. Small intestinal bacterial overgrowth is an example of microbial dysbiosis, with renewed interest in diet being postulated to cause an adaptive change of the microbes colonizing the small intestine. However, the diagnosis of small intestinal bacterial overgrowth is limited by a lack of sensitive and specific tests, with significant knowledge gaps in relation to therapeutic measures to manage and cure small intestinal bacterial overgrowth. Currently, antimicrobials are the established management option. There have been significant clinical advances in dietary interventions related to the small bowel, but this area is currently a novel and advancing field for both patients and clinicians.

OBJECTIVES: Wheat avoidance in the absence of celiac disease (CD) is common but occurrence of concurrent functional gastrointestinal disorders (FGIDs) in this group is uncertain. The aims of this study were to determine the prevalence of self-reported wheat or gluten sensitivity and doctor diagnosed CD in an Australian population, define the associated gastrointestinal (GI) symptoms and FGIDs, and determine the relationship between self-reported wheat sensitivity, demographic and medical factors.Methods: A total of 3542 people randomly selected from the Australian population returned a mail survey which contained questions on wheat avoidance, GI symptoms, demographic, medical, and lifestyle factors. We defined self-reported wheat sensitivity as people who reported gastrointestinal symptoms on ingestion of wheat based foods, but did not suffer from celiac disease, inflammatory bowel disease or colorectal cancer. Functional dyspepsia (FD) and irritable bowel syndrome (IBS) were diagnosed by Rome III criteria. CD status was self-reported.Results: The prevalence of self-reported wheat sensitivity in this cohort was 14.9% (95% CI 13.7-16.2). The prevalence of CD was 1.2% (95%CI 0.8-1.6). Doctor diagnosed CD was significantly associated with a diagnosis of FD (OR 3.35, 95%CI 1.72-6.52) and IBS (OR 2.28, 95%CI 1.08-4.81). Those with self-reported wheat sensitivity were more likely to report multiple abdominal symptoms (of the 18 assessed) than those without (3.9 symptoms with self-reported wheat sensitivity vs. 1.6 without, p = 0.0001). In a multivariate analysis, self-reported wheat sensitivity was independently associated with IBS (OR 3.55, 95%CI 2.71-4.65) and FD (1.48, 95%CI 1.13-1.94).Conclusions: Self-reported wheat sensitivity is common, with a prevalence of 14.9% in this cohort. There is a strong association between both celiac disease and self-reported wheat sensitivity, and chronic gastrointestinal symptoms, as well as a diagnosis of FD and IBS. [ABSTRACT FROM AUTHOR]

Abstract: Background and Aims: A gluten‐free diet (GFD), the mainstay of treatment for celiac disease, is being increasingly adopted by people without this condition. The long‐term health effects of this diet, apart from its beneficial effect on enteropathy in celiac disease, are unclear. Concerns exist that the GFD may result in micronutrient deficiencies, increased exposure to toxins such as arsenic, and an increased cardiovascular risk. This systematic review addresses the effect of the GFD on several modifiable cardiovascular risk factors. Methods: A systematic search of the literature addressing the GFD and blood pressure, glycaemia, body mass index, waist circumference, and serum lipids in patients before and after adoption of a GFD was conducted using the MEDLINE, EMBASE, PSYCInfo, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases. Two authors performed abstract and full text screening, and quality assessment. Results: A total of 5372 articles were identified, from which 27 were included. Lack of control groups in all but one study prevented meta‐analysis of results. Overall study quality was low and restricted to patients with celiac disease. Consistent findings across studies included an increase in total cholesterol, high density lipoprotein, fasting glycaemia, and body mass index (while remaining within the healthy weight range). Significant changes in low density lipoprotein, triglycerides, and blood pressure were not consistently reported. Conclusions: A GFD alters certain cardiovascular risk factors in patients with celiac disease, but the overall effect on cardiovascular risk is unclear. Further studies are warranted.

Background Burn injuries are expensive to treat. Burn injuries have been found to be difficult to treat in elderly patients than their younger counterparts. This is likely to result in higher financial burden on the healthcare system; however, no population-specific study has been conducted to ascertain the inpatient treatment costs of elderly patients with hot tap water burns. Methods Six elderly patients (75-92 years) were admitted for tap water burns at Concord Hospital during 2010. All costs incurred during their hospitalization were followed prospectively, and were apportioned into 'direct' and 'indirect' costs. Direct costs encompassed directly measurable costs, such as consumables used on the ward or in theatres, and indirect costs included hospital overheads, such as bed and theatre costs. Results Three males and three females admitted with burns to the buttocks, legs or feet. Total burn surface area ( TBSA) ranged from 9-21% (mean 12.8%). Length of stay ranged from 26-98 days (mean 46 days). One patient died, and four required surgical management or grafting. Total inpatient costs ranged from $69 782.33 to $254 652.70 per patient (mean $122 800.20, standard deviation $67 484.46). TBSA was directly correlated with length of stay ( P < 0.01) and total cost ( P < 0.01). Conclusion Hot water burns among the elderly are associated with high treatment costs, which are proportional to the size of the burn. The cost of treating this cohort is higher than previously reported in a general Australian burn cohort. [ABSTRACT FROM AUTHOR]

Eosinophilic oesophagitis (EoE) is now a well‐recognised cause of dysphagia and food bolus obstruction (FBO). The diagnosis requires histologic confirmation, and the yield is greatest when at least 4 to 6 oesophageal biopsies are taken from different sites. Previous case reports of FBO have demonstrated a low biopsy rate, and as such cases of EoE may have been missed. In this review, the medical records of 123 patients aged 18 years or older, who had presented with FBO over a 2 year period, were reviewed. EoE was the most common diagnosis, and was found in 81.3% of patients with FBO aged 40 years or less. 45.5% of patients with FBO were biopsied, and of those, 33.9% were confirmed to have had at least 4 biopsies. EoE is a common cause of FBO and requires appropriate oesophageal sampling to confirm the diagnosis. Cases of EoE may otherwise be missed. [ABSTRACT FROM AUTHOR]
