Reports suggest that between 25% and 80% of patients with Streptococcus bovis/gallolyticus bacteremia have concomitant colorectal tumors. This retrospective study was aimed to identify associations between clinical characteristics and a finding of colorectal neoplasm in patients with S. bovis bacteremia who had colonoscopy examination. We retrospectively reviewed the records of patients with S. bovis bacteremia from Kaohsiung Chang Gung Memorial Hospital, Kaohsiung, Taiwan, between January 2004 and January 2014. Clinical data including age, sex, comorbidities, blood culture, and colonoscopy findings were collected and their relationship to a finding of colorectal cancer was examined. A total of 107 patients with S. bovis bacteremia were identified, of whom 49 (72% male; age 65 ± 12 years) were investigated with colonoscopy; 15 of these patients (30.6%) had colorectal adenocarcinoma. Female sex (p = 0.014) and a history of noncolorectal malignancy (p = 0.004) were associated with a finding of colorectal adenocarcinoma. There were no associations with age, percentage of blood cultures, or the presence of diabetes mellitus, chronic liver disease, heart disease, or end-stage renal disease. Our results show that S. bovis bacteremia is associated with the presence of colorectal adenocarcinoma, especially in female patients, and concomitant existence of other malignancies.

AIMTo compare the one-week clinical effects of single doses of dexlansoprazole and esomeprazole on grades A and B erosive esophagitis.METHODSWe enrolled 175 adult patients with gastroesophageal reflux disease (GERD). The patients were randomized in a 1:1 ratio into two sequence groups to define the order in which they received single doses of dexlansoprazole (n = 88) and esomeprazole (n = 87) for an intention-to-treat analysis. The primary end-points were the complete symptom resolution (CSR) rates at days 1, 3, and 7 after drug administration.RESULTSThirteen patients were lost to follow-up, resulting in 81 patients in each group for the per-protocol analysis. The CSRs for both groups were similar at days 1, 3 and 7. In the subgroup analysis, the female patients achieved higher CSRs in the dexlansoprazole group than in the esomeprazole group at day 3 (38.3% vs 18.4%, P = 0.046). An increasing trend toward a higher CSR was observed in the dexlansoprazole group at day 7 (55.3% vs 36.8%, P = 0.09). In the esomeprazole group, female sex was a negative predictive factor for CSR on post-administration day 1 [OR = -1.249 ± 0.543; 95%CI: 0.287 (0.099-0.832), P = 0.022] and day 3 [OR = -1.254 ± 0.519; 95%CI: 0.285 (0.103-0.789), P = 0.016]. Patients with spicy food eating habits achieved lower CSRs on day 1 [37.3% vs 21.4%, OR = -0.969 ± 0.438; 95%CI: 0.380 (0.161-0.896), P = 0.027].CONCLUSIONThe overall CSR for GERD patients was similar at days 1-7 for both the dexlansoprazole and esomeprazole groups, although a higher incidence of CSR was observed on day 3 in female patients who received a single dose of dexlansoprazole.
