LSBE and dysplasia are less frequent in AA than nHw. Studies in AA with BE may illustrate factors limiting dysplasia and LSBE risk.
Esophageal variceal bleeding can be serious or life threatening. Drug-induced thrombocytopenia can further complicate such bleeding episodes. Thrombocytopenia because of sandostatin has been reported in the literature only once previously. We describe a case of sandostatin-induced reversible thrombocytopenia with a positive rechallenge. Platelet count decreased during administration of sandostatin and recovered only when the infusion was halted. The proposed mechanism of thrombocytopenia during both episodes is immunologic. Physician awareness of sandostatin-induced thrombocytopenia can prevent unnecessary complication during episodes of esophageal variceal bleeding and is rapidly reversed with discontinuation of the drug.
Distribution of RE grade and frequency of reflux-related esophageal ulcer, stricture and hiatal hernia are similar in non-Hispanic whites and African Americans. Heartburn was more frequently and nausea/vomiting less frequently reported as the primary endoscopic indication in non-Hispanic whites compared with African Americans with erosive esophagitis or its complications. African Americans have a decreased prevalence of Barrett's esophagus compared with non-Hispanic whites.
Background and study aims Diabetes mellitus (DM) is an independent risk factor for poor bowel preparation prior to colonoscopy. Bisacodyl is a stimulant laxative that may mitigate colonic dysmotility associated with diabetes. We hypothesized that adding bisacodyl to split-dose bowel preparation (SDBP) would improve the quality of bowel preparation among patients with diabetes. Patients and methods Adult outpatients aged 18 to 80 years undergoing colonoscopy were recruited. One hundred and eighty-six patients with diabetes were randomly assigned to 1 of 3 treatment arms: 1) conventional 4 L of polyethylene glycol electrolyte lavage solution (PEG-ELS; conventional bowel preparation [CBP]); 2) split-dose of 4 L PEG-ELS (split-dose bowel preparation [SDBP]); or 3) split-dose of 4 L PEG-ELS preceded by 10 mg of oral bisacodyl 10 (SDBP-B). The primary outcome measure was bowel cleansing as indicated by Boston Bowel Preparation Scale (BBPS) score. Endoscopists were blinded to the preparation used. Secondary outcome measures were safety and patient tolerability. Results Of the 212 patients randomized, only 186 received assigned bowel preparation. There were no differences among the three study groups with regard to age, indication, duration of DM, insulin use, narcotic use, or presence of end-organ diabetic complications. There was a trend toward better bowel preparation quality among those receiving SDBP and SDBP-B compared to those receiving CBP, but the trend was not statistically significant ≥ 6 BBPS; 67 % vs. 83 % vs. 75 %, P = 0.1). In terms of safety and tolerability, there were no differences among the three groups. Conclusion Adding bisacodyl to SDBP does not improve the quality of bowel preparation in patients with DM. Further efforts are needed to optimize colonoscopy bowel preparation in this population.
Background: Barrett's esophagus (BE) is the primary risk factor for esophageal adenocarcinoma (EAC). Limited data exists regarding the frequency of histologically confirmed BE by both gender and ethnicity in the United States. The study aim was to determine whether the frequency of histologically confirmed BE varies by ethnicity and gender. Methods: The University of Florida-Jacksonville endoscopy database was reviewed for all cases of salmon colored esophageal mucosa from September 2002 to August 2007. Histologic BE was diagnosed only if salmon colored esophageal mucosa was seen endoscopically and biopsy confirmed intestinal metaplasia with goblet cells. Data collected included: age at diagnosis, self-reported ethnicity [non-Hispanic white (nHw) or African American (AA)], gender, procedure indication, gastroesophageal reflux disease (GERD) history, atypical manifestations, cigarette smoking, alcohol use, proton pump inhibitor (PPI) use, BE endoscopic length, absence/presence of hiatal hernia, stricture or ulcer, and absence/presence/grade of dysplasia. Results: Salmon colored esophageal mucosa was identified in 391/7,308 patients, distributed ethnically as 306 nHw and 85 AA. Histologic BE was confirmed in 111/391 patients with ethnic distribution of: 95 nHw and 16 AA. Histologically confirmed BE frequency varied both by gender and ethnicity with nHw males having the highest (42.3%) and AA females the lowest (12.3%). Histologically confirmed BE frequency differed significantly between nHw males and nHw/AA females only (P<0.005). Conclusions: Histologically confirmed BE frequency varies by ethnicity and gender with nHw males having the highest frequency/risk and AA females the lowest. Investigation to improve understanding of the impact of race and gender in BE formation should be performed.
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.
