LGD in BE is an overdiagnosed and yet underestimated entity in general practice. Patients diagnosed with LGD should undergo an expert pathology review to purify this group. In case the diagnosis of LGD is confirmed, patients should undergo strict endoscopic follow-up or should be considered for endoscopic ablation therapy.
Constipation is a common problem in people with intellectual disability (ID). Laxatives are frequently prescribed with disappointing results. The prevalence of constipation was investigated in a random population of 215 people with ID (IQ < 50) and constipation was correlated with clinical symptoms. All subjects were scored for bowel habits. Constipation was defined as having a bowel movement less than three times a week or the necessity of using laxatives more than three times a week. Further possible accompanying factors were evaluated. The control subjects were defined as individuals who did not use laxatives. Subjects with constipation were defined as patients and were compared to subjects without constipation (controls). One hundred and forty-nine out of 215 cases (69.3%) showed constipation. Constipation was significantly correlated with non-ambulancy, cerebral palsy, the use of anticonvulsive medication or benzodiazepines, H2-receptor antagonists or proton pump inhibitors, food refusal, and an IQ < 35. Fifty-eight per cent of the patients used bisacodyl or magnesium oxide, 39% lactulose, 13% sodiumlaurylsulphoacetate/sodium citrate/sorbitol and only 10% were given sodium phosphate enemas. Faecal soiling was found in 15% of subjects, while manual evacuation of faeces was performed in nearly 7% of cases. Constipation was randomly demonstrated in almost 70% of the population with ID. Subjects with the above-mentioned accompanying factors are especially at risk for constipation. Contrary to the general population, constipation in people with ID is associated with little use of phosphate enemas, microlax, a low incidence of faecal soiling and manual evacuation of faeces, suggesting an aetiology without distal faecal impaction. The regimen and effect of therapy has to be studied to define adequate treatment schedules.
Surveillance of Barrett's oesophagus allows us to study the evolutionary dynamics of a human neoplasm over time. Here we use multicolour fluorescence in situ hybridization on brush cytology specimens, from two time points with a median interval of 37 months in 195 non-dysplastic Barrett's patients, and a third time point in a subset of 90 patients at a median interval of 36 months, to study clonal evolution at single-cell resolution. Baseline genetic diversity predicts progression and remains in a stable dynamic equilibrium over time. Clonal expansions are rare, being detected once every 36.8 patient years, and growing at an average rate of 1.58 cm2 (95% CI: 0.09–4.06) per year, often involving the p16 locus. This suggests a lack of strong clonal selection in Barrett's and that the malignant potential of ‘benign' Barrett's lesions is predetermined, with important implications for surveillance programs.
An abnormal 24-h pH-metry and symptoms suggestive for GERD were documented frequently in a large cohort of institutionalized intellectually disabled individuals. Further endoscopical evaluation confirmed the diagnosis of reflux esophagitis in the majority of these individuals.
Interobserver agreement for the classification of mucosal morphology was moderate. Although NBI was rated more highly than HR-WLE for imaging quality, this did not result in improved interobserver agreement or increased yield for identifying early neoplasia in Barrett's esophagus. This applied to non-expert as well as expert endoscopists.
Non-experienced endoscopists have better interobserver agreement and accuracy for AFI than for HR-WLE or NBI, indicating that AFI is easier to use for polyp differentiation in non-experienced setting. The newly developed algorithm, combining information of AFI and NBI together, had the highest accuracy and obtained equal results between experienced and non-experienced endoscopists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
