Endoscopy | Year: 2013

Cat scratch colon (CSC) is an entity characterized by bright red linear tears which appear in the colonic mucosa during colonoscopy. Although they do not generally have clinical implications, cases of secondary pneumoperitoneum have been reported. To date, the prevalence, associated diseases, and factors that determine the appearance of CSC have not been adequately determined. We report a series of 20 cases of CSC found in 10715 consecutive colonoscopies. Demographic data, indication for the colonoscopy, endoscopy findings, and complications related to the procedure were recorded. Older age and male sex were significantly associated with CSC. In 15 of the 20 cases the CSC was related to diversion colitis, and 5 cases appeared in patients with collagenous colitis. In patients with diversion colitis, the longer the time elapsed since surgery, the greater the risk of these lesions occurring. None of the patients with CSC had complications related to the colonoscopy. © Georg Thieme Verlag KG · Stuttgart · New York. Source

Gut | Year: 2015

Objective: Intestinal dysbiosis has been associated with coeliac disease (CD), but whether the alterations are cause or consequence of the disease is unknown. This study investigated whether the human leukocyte antigen (HLA)-DQ2 genotype is an independent factor influencing the early gut microbiota composition of healthy infants at family risk of CD. Design: As part of a larger prospective study, a subset (n=22) of exclusively breastfed and vaginally delivered infants with either high genetic risk (HLA-DQ2 carriers) or low genetic risk (non-HLA-DQ2/8 carriers) of developing CD were selected from a cohort of healthy infants with at least one first-degree relative with CD. Infant faecal microbiota was analysed by 16S rRNA gene pyrosequencing and real time quantitative PCR. Results: Infants with a high genetic risk had significantly higher proportions of Firmicutes and Proteobacteria and lower proportions of Actinobacteria compared with low-risk infants. At genus level, high-risk infants had significantly less Bifidobacterium and unclassified Bifidobacteriaceae proportions and more Corynebacterium, Gemella, Clostridium sensu stricto, unclassified Clostridiaceae, unclassified Enterobacteriaceae and Raoultella proportions. Quantitative real time PCR also revealed lower numbers of Bifidobacterium species in infants with high genetic risk than in those with low genetic risk. In high-risk infants negative correlations were identified between Bifidobacterium species and several genera of Proteobacteria (Escherichia/Shigella) and Firmicutes (Clostridium). Conclusions: The genotype of infants at family risk of developing CD, carrying the HLA-DQ2 haplotypes, influences the early gut microbiota composition. This finding suggests that a specific disease-biased host genotype may also select for the first gut colonisers and could contribute to determining disease risk. Source

Objective: To determine pre-/intraoperative risk factors for anastomotic leak after colon resection for cancer and to create a practical instrument for predicting anastomotic leak risk. Background: Anastomotic leak is still the most dreaded complication in colorectal surgery. Many risk factors have been identified to date, but multicentric prospective studies on anastomotic leak after colon resection are lacking. Methods: Fifty-two hospitals participated in this prospective, observational study. Data of 3193 patients, operated for colon cancer with primary anastomosis without stoma, were included in a prospective online database (September 2011-September 2012). Forty-two pre-/intraoperative variables, related to patient, tumor, surgical procedure, and hospital, were analyzed as potential independent risk factors for anastomotic leak (60-day follow-up). A nomogram was created to easily predict the risk of anastomotic leak for a given patient. Results: The anastomotic leak rate was 8.7%, and widely varied between hospitals (variance of 0.24 on the logit scale). Anastomotic leak significantly increased mortality (15.2% vs 1.9% in patients without anastomotic leak, P < 0.0001) and length of hospitalization (median 23 vs 7 days in uncomplicated patients, P < 0.0001). In the multivariate analysis, the following variables were independent risk factors for anastomotic leak: obesity [P = 0.003, odds ratio (OR) = 2.7], preoperative serum total proteins (P = 0.03, OR = 0.7 per g/dL), male sex (P = 0.03, OR = 1.6), ongoing anticoagulant treatment (P = 0.05, OR = 1.8), intraoperative complication (P = 0.03, OR = 2.2), and number of hospital beds (P = 0.04, OR = 0.95 per 100 beds). Conclusions: Anastomotic leak after colon resection for cancer is a frequent, relevant complication. Patients, surgical technique, and hospital are all important determining factors of anastomotic leak risk. © 2015 Wolters Kluwer Health, Inc. Source

Background: The new Global Initiative for Chronic Obstructive Lung Disease (GOLD) update includes airflow limitation, history of COPD exacerbations, and symptoms to classify and grade COPD severity. We aimed to determine their distribution in 11 well-defined COPD cohorts and their prognostic validity up to 10 years to predict time to death. Methods: Spirometry in all 11 cohorts was postbronchodilator. Survival analysis and C statistics were used to compare the two GOLD systems by varying time points. Results: Of 3,633 patients, 1,064 (33.6%) were in new GOLD patient group A (low risk, less symptoms), 515 (16.3%) were B (low risk, more symptoms), 561 (17.7%) were C (high risk, less symptoms), and 1,023 (32.3%) were D (high risk, more symptoms). There was great heterogeneity of this distribution within the cohorts (χ2, P < .01). No differences were seen in the C statistics of old vs new GOLD grading to predict mortality at 1 year (0.635 vs 0.639, P = .53), at 3 years (0.637 vs 0.645, P = .21), or at 10 years (0.639 vs 0.642, P = .76). Conclusions: The new GOLD grading produces an uneven split of the COPD population, onethird each in A and D patient groups, and its prognostic validity to predict time to death is no different than the old GOLD staging based in spirometry only. © 2013 American College of Chest Physicians.

Autologous bone marrow transplant (ABMT) represents a high metabolic stress. Glutamine has proven to be effective in severe catabolic states, although there are controversial studies. To assess the effect of parenteral nutrition (PN) therapy supplemented with glutamine on the occurrence of mucositis and mean hospital stay in patients submitted to ABMT. Retrospective study of patients submitted to ABMT between 2006 and 2009. In 2008, one vial of L-alanyl-L-glutamine (20 g) was added by protocol to the PN formulations of these patients. Thirteen clinical charts since that date (glutamine group) and 13 previous charts (control group) were randomly selected (n = 26). We compared the degree of mucositis and hospital stay in both groups. In the subgroup of glutamine-treated patients, we compare the glutamine dose in the patients developing some degree of mucositis with that of those not having this complication. Mean hospital stay: 27.8 ± 7.4 days (control group) vs. 20.3 ± 5.3 days (glutamine group) (p = 0.01). The severity of mucositis was lower in the glutaminetreated group (p = 0.02). The weight-adjusted dose of L-alanyl-L-glutamine in the patients not developing mucositis was higher than in the other ones (0.32 vs. 0.24 g/kg/day; p = 0.02). Glutamine supplementation reduces the degree of mucositis and hospital stay in patients submitted to autologous bone marrow transplantation. The degree of mucositis is lower in the subgroup of patients receiving higher doses of glutamine. Source
