The histology of the canine intestine has not been accurately defined. To establish the precise thickness of its different layers, whole wall samples of the small intestine were removed from 41 cadavers at five standardised sampling sites (duodenum, proximal jejunum, distal jejunum, proximal ileum and distal ileum). The total thickness was estimated by morphometry, as was the thickness of the mucosa, muscularis mucosae, submucosa and muscularis externa. In addition, the size of the lymphoid aggregates in the submucosa and the thickness of the circular and longitudinal layers within both the muscularis mucosae and the muscularis externa were estimated. The total intestinal thickness depended very much upon the thickness of the mucosa and submucosa. The mucosa decreased progressively from proximal to distal parts of the small intestine (47% reduction). The thickness of the submucosa, however, changed little from the duodenum to the distal jejunum, but increased significantly in the ileum; this change was positively correlated with the amount of lymphoid tissue. Sex influenced the thickness of the intestinal wall, with males displaying higher thickness values along the small intestine. Conversely, no correlation between bodyweight and intestinal thickness was found for any of the five sampling sites. This study gives absolute and relative values for the thickness of the layers of the dog intestine which might help in the diagnosis of small intestinal pathology from postmortem samples and/or endoscopic biopsies. © 2011 Elsevier Ltd.

Distinguishing drug-induced liver injury (DILI) from idiopathic autoimmune hepatitis (AIH) can be challenging. We performed a standardized histologic evaluation to explore potential hallmarks to differentiate AIH versus DILI. Biopsies from patients with clinically well-characterized DILI [n = 35, including 19 hepatocellular injury (HC) and 16 cholestatic/mixed injury (CS)] and AIH (n = 28) were evaluated for Ishak scores, prominent inflammatory cell types in portal and intra-acinar areas, the presence or absence of emperipolesis, rosette formation, and cholestasis in a blinded fashion by four experienced hepatopathologists. Histologic diagnosis was concordant with clinical diagnosis in 65% of cases; but agreement on final diagnosis among the four pathologists was complete in only 46% of cases. Interface hepatitis, focal necrosis, and portal inflammation were present in all evaluated cases, but were more severe in AIH (P < 0.05) than DILI (HC). Portal and intra-acinar plasma cells, rosette formation, and emperiopolesis were features that favored AIH (P < 0.02). A model combining portal inflammation, portal plasma cells, intra-acinar lymphocytes and eosinophils, rosette formation, and canalicular cholestasis yielded an area under the receiver operating characteristic curve (AUROC) of 0.90 in predicting DILI (HC) versus AIH. All Ishak inflammation scores were more severe in AIH than DILI (CS) (P ≤ 0.05). The four AIH-favoring features listed above were consistently more prevalent in AIH, whereas portal neutrophils and intracellular (hepatocellular) cholestasis were more prevalent in DILI (CS) (P < 0.02). The combination of portal inflammation, fibrosis, portal neutrophils and plasma cells, and intracellular (hepatocellular) cholestasis yielded an AUC of 0.91 in predicting DILI (CS) versus AIH. Conclusion: Although an overlap of histologic findings exists for AIH and DILI, sufficient differences exist so that pathologists can use the pattern of injury to suggest the correct diagnosis. © 2011 American Association for the Study of Liver Diseases.

The degree of Knower and compliance with occupational risk prevention measures in the Spanish gastrointestinal endoscopy units is unknown. Aim: 1. To assess compliance with occupational risk prevention measures in GIE units. 2. To determine which factors influence the fulfillment of occupational risk prevention measures. Methods: a validated survey was supplied to 300 GIE units, including questions on: 1. General occupational risk prevention measures; 2. occupational risk prevention measures during disinfection; 3. occupational risk prevention measures during examination. The following Hospital or GIE Unit characteristics were evaluated: Type of hospital according to the Spanish National Health Service; Number of hospital beds; Advanced diagnostic and therapeutic procedures performed and; Centers providing training in the field of endoscopy. Results: response: 196 GIE units (65%). 104 GIE units (53% CI95%: 46-60) fulfill less than 50% of the occupational risk prevention measures studied. The RR of less than 50% of the ORP measures being fulfilled is 1.975 times higher at public hospitals than at private facilities (CI95%: 1.11-3.52). None of the remaining factors analyzed proved to have a significant influence. Conclusions: compliance with occupational risk prevention measures in Spanish GIE units is inadequate and must be improved. Public hospitals in Spain comply with fewer occupational risk prevention measures than their private counterparts. © 2011 ARÁN EDICIONES, S. L. Source

Exploration of the canine small intestine using conventional endoscopy is restricted to the duodenum and/or the ileum. Double balloon endoscopy (DBE) is a 'push and pull' technique that has been described in humans and permits a complete exploration of the small intestine. In this study, oral DBE was performed on 12 healthy dogs (10-34. kg) to characterize for the first time the efficiency, exploration dynamics and safety of the technique. DBE was successful in 83% of dogs; the average estimated insertion depth of the endoscope was 287 ± 36. cm, and the average duration of the exploration was 84 ± 8. min. No complications or relevant adverse clinical effects were observed, and there was no indication of post-procedure pancreatitis based on serology of two specific markers of pancreatitis (amylase and lipase) and the immediate nonspecific inflammatory mediator C-reactive protein. The study showed that oral DBE is viable and safe in the dog, allowing for the diagnosis and treatment of gastrointestinal diseases deep in the small intestine to an extent that has not previously been possible using conventional endoscopy. © 2012 Elsevier Ltd.

Objective: Epidemiological evidence suggests an association between psychological factors and functional dyspepsia (FD). Yet few randomized controlled trials (RCTs) of psychological interventions have been conducted for FD. We conducted an RCT to evaluate the efficacy of psychotherapy among chronic FD. Methods: One hundred fifty-eight consecutive patients with FD were randomized to medical therapy plus psychotherapy consisted in 8 group and 2 individual sessions focused on teaching techniques for coping with FD (intensive treatment (IT); n = 76) or medical therapy alone (conventional treatment (CT); n = 82). Patients completed validated self-reported questionnaires before and after the 10-week treatment and 6. months later. Linear mixed-effects models were used, in intention-to-treat analysis. Results: At the end of treatment period, statistically significant improvements were observed for IT compared with CT for dyspepsia-related quality of life (DRQoL). DRQoL mean changes of 6.09 and 3.54 were obtained in IT and CT patients, respectively (p=<0.0001); and SS mean changes of 11.55 and 4.57 were obtained in IT and CT patients, respectively (p=0.0013). Those improvements, measured by minimum clinically important difference (MCID), were clinically significant (DRQoL: 77% of the IT patients exceeded the MCID vs the 45% of the CT; SS: 75% vs 48%). Six months after treatment, those statistically significant improvements persisted for DRQoL (p = 0.0067) and for SS (p = 0.0405). Clinical improvements persisted for SS (63% vs 41%). Conclusions: These findings suggest that adding psychotherapy to standard medical therapy improves short-term outcomes in patients with FD and may have long-term effects as well. The cost-effectiveness of intensive therapy needs to be evaluated. Registration number and name of trial registry: NCT01802710. © 2015 Elsevier Inc. Source
