BACKGROUND: Inflammatory bowel diseases (IBD) are chronic inflammatory affections of recurrent nature whose incidence and prevalence rates have increased, including in Brazil. In long term, they are responsible for structural damage that impacts quality of life, morbidity and mortality of patients. OBJECTIVE: To describe the profile of physicians who treat IBD patients as well as the characteristics of IBD care, unmet demands and difficulties. METHODS: A questionnaire containing 17 items was prepared and sent to 286 physicians from 101 Brazilian cities across 21 states and the Federal District, selected from the register of the State Commission of the “Study Group of Inflammatory Bowel Disease of Brazil” (GEDIIB). RESULTS: The majority of the physicians who answered the questionnaire were gastroenterologists and colorectal surgeons. More than 60% had up to 20 years of experience in the specialty and 53.14% worked at three or more locations. Difficulties in accessing or releasing medicines were evident in this questionnaire, as was referrals to allied healthy professionals working in IBD-related fields. More than 75% of physicians reported difficulties in performing double-balloon enteroscopy and capsule endoscopy, and 67.8% reported difficulties in measuring calprotectin. With regard to the number of patients seen by each physician, it was shown that patients do not concentrate under the responsibility of few doctors. Infliximab and adalimumab were the most commonly used biological medicines and there was a higher prescription of 5-ASA derivatives for ulcerative colitis than for Crohn’s disease. Steroids were prescribed to a smaller proportion of patients in both diseases. The topics “biological therapy failure” and “new drugs” were reported as those with higher priority for discussion in medical congresses. In relation to possible differences among the country’s regions, physicians from the North region reported greater difficulty in accessing complementary exams while those from the Northeast region indicated greater difficulty in accessing or releasing medicines. CONCLUSION: The data obtained through this study demonstrate the profile of specialized medical care in IBD and are a useful tool for the implementation of government policies and for the Brazilian society as a whole.

According to several epidemiological studies, there is a significant increase in cases of inflammatory disease in developing countries. Objective To describe epidemiological data and clinical features of patients with inflammatory bowel disease in patients enrolled in Campo Grande, MS. Method A retrospective descriptive study with a database analysis of patients who were enrolled and renewed their process in the Exceptional Medications Program of the Health Department from January 2008 to December 2016. Results 423 patients participated in the study, 260 women and 163 men. Of these, 238 patients had Crohn's disease and 185 had ulcerative rectocolitis. The patients’ mean age was 46 years. The most commonly used medication for both diseases was mesalazine and 34.3% of the patients needed to switch their medication during the treatment, most of them with Crohn's disease. In Crohn's patients, the most affected segment was the colon (40.6%) and in patients with ulcerative rectocolitis the entire large intestine was involved (78.8%) was more common. Of the total number of patients, 10.8% of the women and 18.4% of the men needed to use an anti-TNF. Conclusion Most people on treatment for IBD are female, with a mean age of 46 years and suffering from Crohn's disease. The most affected segments were the entire large intestine in URC cases and the colon in Crohn's disease cases. Mesalazine was the most used drug in both diseases. There was more drug replacement in Crohn's disease patients. In Crohn's disease, younger patients used infliximab more frequently.

Introduction the management of anal fistula remains debatable. The lack of a standard treatment free of complications stimulates the development of new options. Objective to develop an experimental model of anal fistula in rats. Methods to surgically create an anal fistula in 10 rats with Seton introduced through the anal sphincter musculature.The animals were euthanized for histological fistula tract assessment. Results all ten specimens histologically assessed had a lumen and surrounding granulation tissue. There was complete epithelialization of the tract in two samples, halfway epithelialization in one sample and epithelialization of only the outer portion in six samples. Epithelialization was not evident in one tract. Conclusion anal fistulas in rats were histologically proved.

ObjectiveTo assess the effects of postconditioning remote in ischemia-reperfusion injury in rat lungs.MethodsWistar rats (n=24) divided into 3 groups: GA (I/R) n=8, GB (R-Po) n=8, CG (control) n=8, underwent ischemia for 30 minutes artery occlusion abdominal aorta, followed by reperfusion for 60 minutes. Resected lungs and performed histological analysis and classification of morphological findings in accordance with the degree of tissue injury. Statistical analysis of the mean rating of the degree of tissue injury.ResultsGA (3.6), GB (1.3) and CG (1.0). (GA GB X P<0.05).ConclusionThe remote postconditioning was able to minimize the inflammatory lesion of the lung parenchyma of rats undergoing ischemia and reperfusion process.

Avaliação do pós-condicionamento isquêmico no tratamento da isquemia mesentérica. Estudo experimental em ratosEvaluation of ischemic postconditioning effect on mesenteric ischemia treatment. Experimental study in rats Abstract Objective: To assess the preconditioning and postconditioning effect on intestinal mucosal lesions in rats undergone mesenteric ischemia and reperfusion procedure.Methods: Thirty Wistar rats were studied and divided into three groups: Group A, 10 rats undergone mesenteric ischemia (30 minutes) and reperfusion (60 minutes); Group B, 10 rats undergone mesenteric ischemia and reperfusion preceded by ischemic preconditioning for three cycles of ischemia and reperfusion for two minutes each; Group C, 10 rats undergone mesenteric ischemia and reperfusion and, preceding the beginning of reperfusion, ischemic postconditioning was performed for three cycles of reperfusion and ischemia for two minutes each. Then, a segment of small intestine was resected for histological analysis. We assessed the results by Chiu et al. score and the statistical analysis was performed.Results: According to Chiu et al. score, the means of lesion degree were: In the group A, 3.5; Group B, 1.2; Group C, 1. The difference between group A with the groups B and C was considered statistically significant (P < 0.05).Conclusion: Ischemic pre-and postconditioning were capable of minimizing -in a similar intensity -the tissue injury on the intestinal mucosa of rats undergone mesenteric ischemia and reperfusion process. Resumo Objetivo: Avaliar o efeito do pré e pós-condicionamento isquêmico sobre a lesão tecidual na mucosa intestinal de ratos submetidos ao processo de isquemia e reperfusão mesentérica.

BackgroundThe abscesses and anal fistulas represent about 70% of perianal suppuration, with an estimated incidence of 1/10000 inhabitants per year and representing 5% of queries in coloproctology.AimTo evaluate the effectiveness of the interesphincteric ligation technique of the fistulous tract in the treatment of anal fistula.MethodsThe records of eight patients who underwent this technique, evaluating age, gender and presence of incontinence were studied. Was named technical first-step the passage of cotton thread to promote the correct individualization of the fistula and, as the second, the surgical procedure.ResultsTwo patients were men and eight women. The mean age was 42.8 years. Of these, seven (87.5%) had complete healing of the fistula; six were cured only with this procedure and one required additional operation with simple fistulotomy. Only one patient developed fecal incontinence which was documented by anorectal manometry. There were no deaths in this series.ConclusionThe interesphincteric ligation technique of the fistulous tract proved to be effective for the treatment of anal fistula and should not be discouraged despite the occurrence of eventual fecal incontinence.

Ischemic postconditioning was able to minimize reperfusion injury of rats undergone mesenteric ischemia and reperfusion process. There was no difference in the effectiveness of the method comparing two cycles of two minutes with four cycles of 30 seconds by H&E histological evaluation of the ileum after 60-minute reperfusion.
