    Full Text Available OBJECTIVE: To evaluate the results of ileal J-pouch anal anastomosis in ulcerative colitis and familial adenomatous polyposis. METHOD: Retrospective analysis of medical records of 49 patients submitted to ileal J-pouch anal anastomosis. RESULTS: Ulcerative colitis was diagnosed in 65% and familial adenomatous polyposis in 34%. Mean age was 39.5 years. 43% were male. Among familial adenomatous polyposis, 61% were diagnosed with colorectal cancer. Thirty-one percent of patients with ulcerative colitis was submitted to a previous surgical approach and 21% of these had toxic megacolon. Average hospital stay was 10 days. Post-operative complications occurred in 50% of patients with ulcerative colitis and 29.4% with familial adenomatous polyposis. Intestinal diversion was performed in 100% of ulcerative colitis and 88% of familial adenomatous polyposis. Pouchitis occurred in eight cases (seven ulcerative colitis and one FAP, requiring excision of the pouch in three ulcerative colitis. Mortality rate was 7.6%: two cases of carcinoma on the pouch and two post-operative complications. Late post-operative complications occurred in 22.4%: six familial adenomatous polyposis and five ulcerative colitis. Two patients had erectile dysfunction, and one retrograde ejaculation. One patient with severe perineal dermatitis was submitted to excision of the pouch. Incontinence occurred in four patients and two reported soil. Mean bowel movement was five times a day. CONCLUSION: Ileal J-pouch anal anastomosis is a safe surgery with acceptable morbidity and good functional results, if well indicated and performed in referral centers.OBJETIVO: Avaliar resultados da anastomose íleo-anal com bolsa ileal em J na colite ulcerativa e na polipose adenomatosa familiar.

    Ileal pouch anal anastomosis (IPAA) may alter sexuality and fertility in women. The laparoscopic approach seems to reduce infertility rates in women after IPAA. However, the impact of hand sewn versus stapled IPAA on sexuality and fertility has never been assessed in patients with ulcerative colitis (UC). The objective of this study was to analyze the impact of the IPAA technique on sexuality and fertility in UC. All UC patients who underwent an IPAA between May 1996 and April 2011 were included. The patients answered mailed questionnaires including sexuality validated questionnaires and fertility questionnaires. The risk factors of sexual dysfunction were explored. A total of 135 patients were included. Eighty-eight patients (65%) answered the questionnaires. Their mean age and follow-up were 37.2 ± 13.4 y and 109.7 ± 57.5 mo. The rates of female and male sexual dysfunction were 50% and 29%, respectively. Intestinal transit disorders were identified as risk factors in both men and women and anastomotic stricture in women sexual dysfunction, in univariate analyses. The IPAA technique did not impact sexual function in women but there was a trend for less erectile dysfunction after hand sewn IPAA (16.7% versus 44.4%). The fertility rate was 47% in women and 75% in men, with a trend for a better fertility in women after hand sewn IPAA (P = 0.07). In this preliminary study, the hand sewn or stapled IPAA technique did not impact the sexuality or fertility outcomes of UC patients, but there was a trend for better female fertility and male erectile function after hand sewn IPAA. Intestinal transit disorders contributed to male and female sexual dysfunction after IPAA. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available O óxido nítrico (NO é um radical livre sintetizado endogenamente por várias células do nosso organismo. Apresenta um amplo espectro de ações fisiológicas, sendo as mais importantes o seu mecanismo de ação parácrino no relaxamento da musculatura lisa, sua atividade neurotransmissora em vários sistemas e seu envolvimento no processo inflamatório. O NO é sintetizado em diferentes tecidos através da conversão da L-arginina em L-citrulina pela ação da enzima óxido nítrico sintase (NOS. OBJETIVOS: Este estudo tem por objetivo demonstrar o envolvimento do óxido nítrico no processo intestinal inflamatório de ratos Wistar submetidos à colite experimental com ácido acético. MATERIAL E MÉTODOS: Foram utilizados 20 ratos machos Wistar, com peso entre 250 e 350 gramas divididos em dois grupos de 10 animais. Os animais do grupo em estudo foram submetidos à administração intracolônica, por enema, de uma solução de ácido acético diluído a 7% e com volume de 3 ml. O grupo controle recebeu apenas enema de solução salina. Foram avaliados os índices histológicos, a expressão da enzima óxido nítrico sintase (iNOS e a pressão anal esfincteriana. RESULTADOS: Os índices histológicos apresentaram uma significativa elevação no grupo colite quando comparados ao grupo controle, tanto na avaliação macroscópica quanto na microscópica. A expressão da enzima iNOS também foi significativamente maior no grupo colite quando comparada ao grupo controle. A pressão anal esfincteriana foi significativamente mais baixa no grupo colite na comparação ao grupo controle. CONCLUSÃO: Os animais submetidos à colite experimental apresentam um aumento da expressão da enzima óxido nítrico sintase induzível (i-NOS. Este aumento, associado ao conseqüente aumento do nível de óxido nítrico, ocasiona uma diminuição dos níveis de pressão anal esfincteriana.The nitric oxide (NO is a free radical synthesized from some cells of our

    Robotic surgery offers advantages for operating in a narrow space such as inside the pelvis. We report on the technique of robotic-assisted laparoscopic total proctocolectomy with lymphadenectomy and ileal pouch-anal anastomosis for ulcerative colitis with transverse colitic cancer, using the single cart position. A 46-year-old female patient was diagnosed with colitic cancer of the transverse colon during the surveillance of ulcerative colitis. Six port sites were used. Mobilization of the left-sided colon through to the rectum and mobilization of the transverse colon with lymphadenectomy around the middle colic artery were performed using the robotic surgical system. After rectal mobilization was conducted near the anus, the right side of the colon was mobilized and the ileum resected laparoscopically. Thereafter, a mucosectomy of the proctorectum was carried out through a trans-anal approach, and a hand-sewn J-pouch was performed. Finally, a diverting ileostomy was constructed through the right lower abdomen. The operative time was 460 minutes, including the console time of 361 minutes. The amount of blood loss was 76 g. The patient was discharged on postoperative day nine. Pathological results demonstrated that the depth of the lesion was T3, and the positive lymph node was 1 of 115 retrieved lymph nodes. There were no complications or mortality. Robotic-assisted total proctocolectomy and lymphadenectomy with ileal pouch-anal anastomosis for transverse colitic cancer of ulcerative colitis was performed safely using the single cart position.

    Full Text Available Background: Few cases of pouch-related cancers have been reported in ulcerative colitis (UC, and squamous cell carcinoma (SCC is very rare. Method: A systematic review of the literature was performed to identify all unequivocal cases of pouch-related SCC in UC patients. Results: Eight cases of SCC developing after ileal pouch-anal anastomosis (IPAA have been observed since 1978. Two arose from the pouch mucosa and 6 from below. The pooled cumulative incidence of SCC is below 0.06% after IPAA. Many patients had neoplasia on the preoperative specimen, but squamous metaplasia of the pouch or anorectal mucosa may have an important role in SCC. These patients are rarely offered chemoradiation therapy and the outcome is poor. Selected patients with SCC located close to the pouch outlet can be treated with chemoradiation prior to consideration of surgery and salvage their pouch. A chemoradiation regimen is suggested to avoid pouch excision in these patients. Conclusions: SCC is rare after pouch surgery but associated with extremely poor survival. Very low SCC can be managed with chemoradiation treatment, preserving the pouch and avoiding surgery, even in older patients. The role of pouch metaplasia, surveillance frequency, and treatment modalities after IPAA need further studying.

    The incidence of neoplasia after surgery has not been sufficiently evaluated in patients with ulcerative colitis (UC), particularly in the Japanese population, and it is not clear whether surveillance endoscopy is effective in detecting dysplasia/cancer in the remnant rectum or pouch. The aims of this study were to assess and compare postoperative development of dysplasia/cancer in patients with UC who underwent ileorectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA) and to evaluate the effectiveness of postoperative surveillance endoscopy. One hundred twenty patients who received postoperative surveillance endoscopy were retrospectively reviewed for development of dysplasia/cancer in the remnant rectal mucosa or pouch. Three hundred seventy-nine endoscopy sessions were conducted for 30 patients after IRA, while 548 pouch endoscopy sessions were conducted for 90 patients after IPAA. In the IRA group, 5 patients developed dysplasia/cancer during postoperative surveillance and in all cases, neoplasia was detected at an early stage. In the IRA group, no patient developed neoplasia within 10 years of diagnosis; the cumulative incidence of neoplasia after disease onset was 7.2, 12.0, and 23.9% at 15, 20, and 25 years, respectively. In one case after stapled IPAA, dysplasia was found at the ileal pouch; a subsequent 9 endoscopy sessions in 8 years did not detect any dysplasia. Neoplasia was found more frequently during postoperative surveillance in the IRA group than in the IPAA group (p = .0028). The cumulative incidence of neoplasia after IRA was 3.8, 8.7, and 21.7% at 10, 15, and 20 years, respectively, and that after IPAA was 1.6% at 20 years. The cumulative incidence of neoplasia after IPAA was minimal. Those who underwent IRA had a greater risk of developing neoplasia than those who underwent IPAA, although postoperative surveillance endoscopy was able to detect dysplasia/cancer at an early stage. IRA can be the surgical procedure of choice only in

    Pouchitis is a common and troublesome condition in patients operated on with ileal-pouch-anal-anastomosis (IPAA). A disturbed microecology in the pouch has been suggested as one possible explanation. In a previous double-blind, randomized, controlled study we demonstrated clinical improvement of symptoms in patients with ulcerative colitis (UC) operated on with IPAA, during intervention with live probiotic microbes Lactobacilli and Bifidobacteriae. The aim of the present study was to confirm our previous results in a much larger material, including clinical symptoms, faecal flora and endoscopic evaluation, and to compare the results in UC/IPAA patients with those of patients with familial adenomatous polyposis (FAP) with IPAA and UC patients with ileorectal anastomosis (IRA). Five hundred millilitres of a fermented milk product (Cultura) containing live lactobacilli (La-5) and bifidobacteriae (Bb-12) was given daily for 4 weeks to 51 UC patients and 10 patients with FAP, operated on with IPAA, and six UC patients operated on for IRA. Stool samples were cultured for examination of lactobacilli, bifidobacteriae, fungi and pH before, during and after intervention. Before, during and after intervention, endoscopic evaluation was performed. Categorized symptomatology was examined prospectively using diary cards in addition to an interview, before and on the last day of intervention. The number of lactobacilli and bifidobacteriae increased significantly during intervention in the UC patients operated on with IPAA and remained significantly increased one week after intervention. Involuntary defecation, leakage, abdominal cramps and the need for napkins (category I), faecal number and consistency (category II) and mucus and urge to evacuate stools (category III) were significantly decreased during intervention in the UC/IPAA group. In the FAP group there was a significant decrease in faecal leakage, abdominal cramps and use of napkins (category I) during intervention. The

    Full Text Available OBJETIVOS: Descrever um caso de lesão anal causada por infecção pelo papilomavírus humano em uma mulher vivendo com HIV/aids. DESCRIÇÃO DO CASO: Mulher de 35 anos, diagnosticada há cinco anos com HIV, relatou prurido e sangramento anal, dor ao defecar e visualização de pequenas verrugas na região perianal. Atendida em um serviço de atenção especializada, foi submetida a exame clínico com inspeção visual, o qual revelou condiloma na região perianal. O exame histopatológico confirmou a presença de displasia de grau moderado a acentuado associado a alterações compatíveis com infecção pelo papilomavírus humano. A paciente foi encaminhada para exérese da lesão. No início dos sintomas, a paciente ainda não fazia uso da terapia antirretroviral e apresentava a maior carga viral do HIV de seu histórico laboratorial, com 2. 951 cópias/ml. Também havia passado por estresse emocional e estava com infecções genitais recorrentes pelo vírus Herpes simplex. Esses fatores podem ter contribuído para o desenvolvimento do condiloma anal. CONCLUSÕES: A possibilidade de que a infecção pelo HIV possa alterar a história da infecção pelo HPV alerta para que nessas situações sejam adotadas estratégias rigorosas de rastreamento através do exame citológico, tanto do colo do útero como da região anal

    Full Text Available Ileal pouch-anal anastomosis was an important advancement in the treatment of ulcerative colitis. The aim of this study was to determine whether early complications of ileal pouch-anal anastomosis in patients with ulcerative colitis are associated with poor late functional results. PATIENTS AND METHODS: Eighty patients were operated on from 1986 to 2000, 62 patients with ileostomy and 18 without. The early and late complications were recorded. Specific emphasis has been placed on the incidence of pouchitis with prolonged follow-up. RESULTS: The ileostomy was closed an average of 9.2 months after the first operation. Fourteen patients were excluded from the long-term evaluation; 6 patients were lost to regular follow-up, 4 died, and 4 patients still have the ileostomy. Of the 4 patients that died, 1 died from surgical complications. Early complications after operation (41 occurred in 34 patients (42.5%. Late complications (29 occurred in 25 patients as follows: 16 had pouchitis, 3 associated with stenosis and 1 with sexual dysfunction; 5 had stenosis; and there was 1 case each of incisional hernia, ileoanal fistula, hepatic cancer, and endometriosis. Pouchitis occurred in 6 patients (9.8% 1 year after ileal pouch-anal anastomosis, 9 (14.8% after 3 years, 13 (21.3% after 5 years, and 16 (26.2% after more than 6 years. The mean daily stool frequency was 12 before and 5.8 after operation. One pouch was removed because of fistulas that appeared 2 years later. CONCLUSIONS: Ileal pouch-anal anastomosis is associated with a considerable number of early complications. There was no correlation between pouchitis and severe disease, operation with or without ileostomy, or early postoperative complications. The incidence of pouchitis was directly proportional to duration of time of follow-up.A anastomose íleo-anal com reservatório ileal foi um importante avanço no tratamento da retocolite ulcerativa.

    Full Text Available Este artículo se compone de dos partes. En la primera se identifican las tendencias que enmarcan las transformaciones ocurridas en la industria de artes gráficas, imprentas y editoriales en las dos últimas décadas del siglo XX. Entre estas se destacan la conformación de grupos empresariales en medio de un notable impacto del cambio técnico impulsado por la digitalización de la producción gráfica y una acelerada convergencia tecnológica que propicia la integración de la industria gráfica con las de la información, la comunicación y el entretenimiento. A causa de ello esta industria está inmersa en una reconfiguración que afecta su morfología. En la segunda parte, se intentan dilucidar los retos analíticos que se desprenden de las transformaciones detectadas, y se plantea que para interpretar la dinámica de las transformaciones empresariales detectadas y el papel vital que en ellas juega el cambio técnico se pueden integrar los aportes de la teoría de los costos de transacción, la perspectiva evolutiva del cambio técnico y el enfoque de los recursos y las capacidades. Se sugiere, igualmente, que síntesis analíticas como la propuesta reclaman una apertura disciplinaria concordante con los desafíos que abren transformaciones empresariales como la descrita en la primera parte del artículo y que poco se han estudiado en el país.

    Recent studies have demonstrated the benefits of immunomodulators, such as arginine, in the regulation of inflammatory responses and trophism of the intestinal mucosa. The aim of this study was to evaluate the possible mechanisms action of arginine (pretreatment or treatment) in experimental model of ulcerative colitis induced by dextran sodium sulfate (DSS). C57BL/6 mice were randomized into 5 groups: Control group (C): standard diet and water; Arginine group (ARG): diet supplementation with arginine and water; Colitis group (COL): standard diet and DSS solution; Pretreated group (PT): diet supplementation with arginine before and during colitis induction; Treated group (T): diet supplementation with arginine during colitis induction. Colitis was induced by administration of 1.5% DSS for 5 days. After this, all the mice were euthanized and blood, organs and intestinal fluid were collected for carrying out analyzes. Parameters such as intestinal permeability (IP), bacterial translocation (BT), histological analysis (histological score, morphometric analysis, collagen and mucins stain), nitrate and nitrite, cytokines and chemokines, secretory immunoglobulin A (sIgA), inflammatory infiltrate and oxidative stress were performed. The ARG group did not show difference compared to group C in the investigated parameters (C vs ARG: p> 0.05). The COL group showed increased IP (C vs COL: p < 0.05) and BT (C vs COL: p <0.05). In the histological analysis, the COL group showed severe inflammation and reduction the crypts length. In addition, in the group COL observed increase infiltration of eosinophils, neutrophils and macrophages in the colon, increase cytokine IL-17 and chemokine KC in serum and oxidative stress in the colon (COL vs C: p <0.05). In the arginine-supplemented groups (PT and T) was observed decrease IP and BT to blood, liver and lung (PT and T vs Col: p <0.05). Histological analysis showed that the arginine (PT and T) preserved the intestinal mucosa and crypts

    Turner syndrome is a chromosomal disease frequently associated with autoimmune disorders including diabetes mellitus, thyroid disease and inflammatory bowel disease (IBD). Although the etiology of IBD has not been fully elucidated, genetic analysis has recently revealed several susceptibility genes. Recently, cases with Turner syndrome associated with IBD have been reported. We report here a 13-yr-old girl with Turner syndrome associated with ulcerative colitis. The patient was undergoing growth hormone treatment and presented with abdominal discomfort and bloody diarrhea. Her karyotype pattern was 46,X,i(Xq). Barium enema revealed punctate collections of barium suggesting microulcerations in the descending and sigmoid colon with loss of haustra. Flexible sigmoidoscopy showed that the mucosa was erythematous and friable upon touch and that the wall had frank hemorrhage and inflammatory polyp formation from the anal verge through the splenic flexure. Histologically, mucosal and submucosal inflammation was prominent, suggesting cryptitis and crypt abscess formation. Based on these findings, she was diagnosed as having ulcerative colitis, and 5-aminosalicylic acid, prednisolone and dietary therapy were initiated. Our observations in this patient suggest that X chromosome abnormality may influence the development of IBD and that screening for gastrointestinal disease in patients with Turner syndrome may help lengthen life expectancy in these patients.

    Full Text Available O objetivo do estudo foi analisar o inconsciente de diferentes grupos de alunos quanto a aceitação dos métodos de custeio variável e por absorção, fundamentando-se na teoria de psicologia analítica desenvolvida por Jung (1936 sobre arquétipos e inconsciente coletivo. A pesquisa foi realizada com discentes de Ciências Contábeis de uma universidade baiana e outra catarinense em uma amostra de 150 respondentes. Utilizou-se os procedimentos estatísticos do teste de comparação de médias e análise descritiva dos dados para a realização das inferências sob o objeto de estudo. Os resultados indicam que os estudantes mudam a postura e tendem a apresentar uma maior aderência às concepções teóricas do custeio variável para fins gerenciais, após cursarem a disciplina de contabilidade de custos. Esta mudança não ocorre no grupo de alunos que possui experiência profissional na área contábil, o que sugere a existência de um tipo específico de inconsciente coletivo relacionado ao uso de sistemas de contabilidade baseados na contabilidade financeira. Verificou-se que os estudantes não possuem clara definição das diferenças existentes entre os métodos de custeio variável e por absorção, uma vez que a maioria dos participantes da pesquisa considera o custeio por absorção importante para a tomada de decisões, além de afirmarem que existe pouca diferença entre estes métodos. A falta de profundidade no ensino dos conteúdos desta disciplina pode ser um fator que explique por que os discentes não claramente discriminam as diferenças entre a utilização de ambos os métodos para fins gerenciais, bem como os aspectos financeiros e gerenciais da contabilidade.

    PURPOSE: Ileal pouch-anal anastomosis remains the "gold standard" in surgical treatment of ulcerative colitis and familial adenomatous polyposis. Pouchitis occurs mainly in patients with a background of ulcerative colitis, although the reasons for this are unknown. The aim of this study was to characterize differences in pouch bacterial populations between ulcerative colitis and familial adenomatous pouches. METHODS: After ethical approval was obtained, fresh stool samples were collected from patients with ulcerative colitis pouches (n = 10), familial adenomatous polyposis (n = 7) pouches, and ulcerative colitis ileostomies (n = 8). Quantitative measurements of aerobic and anaerobic bacteria were performed. RESULTS: Sulfate-reducing bacteria were isolated from 80 percent (n = 8) of ulcerative colitis pouches. Sulfate-reducing bacteria were absent from familial adenomatous polyposis pouches and also from ulcerative colitis ileostomy effluent. Pouch Lactobacilli, Bifidobacterium, Bacteroides sp, and Clostridium perfringens counts were increased relative to ileostomy counts in patients with ulcerative colitis. Total pouch enterococci and coliform counts were also increased relative to ileostomy levels. There were no significant quantitative or qualitative differences between pouch types when these bacteria were evaluated. CONCLUSIONS: Sulfate-reducing bacteria are exclusive to patients with a background of ulcerative colitis. Not all ulcerative colitis pouches harbor sulfate-reducing bacteria because two ulcerative colitis pouches in this study were free of the latter. They are not present in familial adenomatous polyposis pouches or in ileostomy effluent collected from patients with ulcerative colitis. Total bacterial counts increase in ulcerative colitis pouches after stoma closure. Levels of Lactobacilli, Bifidobacterium, Bacteroides sp, Clostridium perfringens, enterococci, and coliforms were similar in both pouch groups. Because sulfate-reducing bacteria are

    Full Text Available Embalagens de papelão ondulado para produtos hortícolas têm como função principal a proteção do produto. O dimensionamento de uma embalagem de papelão requer o conhecimento da rigidez à flexão, que depende dos módulos de elasticidade dos elementos que o constituem. Este trabalho teve por objetivo calcular, a partir da caracterização física do papelão em laboratório, o módulo de elasticidade por diferentes métodos, comparando os resultados com os valores obtidos experimentalmente. Dez corpos de prova de cada um dos papéis selecionados para este estudo foram testados na direção de fabricação e na direção transversal. A resistência à tração dos papéis, capa e miolo, utilizada para calcular a rigidez, foi determinada em máquina universal de ensaios. Para a obtenção da rigidez à flexão, foi realizado o teste de quatro pontos. Foi observada expressiva variação entre os métodos pelos quais se obtêm os módulos de elasticidade que reflete nos valores de rigidez da estrutura. Os valores de rigidez obtidos experimentalmente foram sempre superiores aos valores obtidos por cálculos analíticos. Essa diferença pode ser atribuída a dois fatores conjugados: o processo de fabricação que confere maior rigidez do que os componentes isoladamente, e o outro componente é a adição de camada adesiva que não é levada em consideração nos cálculos analíticos.Cardboard packing for horticultural products has as main function to protect them.

    Restorative proctocolectomy is the most common operation in patients with ulcerative colitis. The aim was to evaluate long-term changes in our operative treatment and early and late complications related to restorative proctocolectomy. The study comprised 352 (149 females) patients over 18 years of age with ulcerative colitis who underwent restorative proctocolectomy in 1985-2009 median follow-up time of 5 years. The indication for surgery was active chronic colitis in 168 (47.7%), acute colitis in 159 (45.2%), and cancer or dysplasia in 25 (7.1%) patients. Ileal pouch-anal anastomosis was performed using hand-sewn anastomosis with mucosectomy in 283 patients and stapled anastomosis in 69. A shift from hand-sewn to stapler ileal pouch-anal anastomosis took place in 2005. Covering ileostomy was carried out in 133 (37.8%) patients. There were 82 (23.3%) J-pouch-related complications. The operative mortality was 0.3%. There were significantly fewer leakages and early re-operations when covering ileostomy was used than when it was omitted: 6.0% versus 16.4% (p = 0.004), 4.5% versus 11.9% (p = 0.02), respectively. There were more strictures in hand-sewn than in stapled ileal pouch-anal anastomoses (17.6% vs. 0%, p = 0.001). Pouchitis occurred at least once in 134 (38.1%) patients. The ileal pouch-anal anastomosis technique used in restorative proctocolectomy had changed over the past years from hand-sewn to stapled anastomosis. Covering ileostomy seemed to protect against major complications. Pouchitis was the most common late complication. © The Finnish Surgical Society 2015.

    The extent of preoperative small-bowel mucosal inflammation may be an important predictor of pouchitis after ileal pouch-anal anastomosis. This study examined the value of preoperative wireless capsule endoscopy in predicting outcome of ileal pouch-anal anastomosis in patients with ulcerative colitis or indeterminate colitis. Patients undergoing complete wireless capsule endoscopy before ileal pouch-anal anastomosis were identified. Findings on wireless capsule endoscopy were classified as positive (erosions, ulcers or erythema) or negative. Outcome was assessed prospectively and included no pouchitis, acute pouchitis, chronic pouchitis, or de novo Crohn disease. Patients with acute pouchitis, chronic pouchitis, or de novo Crohn disease were considered to have pouch inflammation. The 68 study patients (48 ulcerative colitis; 20 indeterminate colitis) had a median age of 38 years and included 34 males. Median follow-up time after ileostomy closure was 12 months (range, 3-63 months). Wireless capsule endoscopy was positive in 15 patients (22%) and negative in 53 patients (78%). Pouch inflammation was observed in 23 patients (34%), and included 8 patients with acute pouchitis, 3 patients with chronic pouchitis, and 12 patients with de novo Crohn disease. The incidence of acute pouchitis, chronic pouchitis, de novo Crohn disease, and pouch inflammation in the wireless capsule endoscopy-positive patient group was 7%, 7%, 20%, and 33% compared with 13%, 4%, 17%, and 34% in the wireless capsule endoscopy-negative patient group (all P = NS). There was no statistical association between the results of preoperative wireless capsule endoscopy and outcome after ileal pouch-anal anastomosis in patients with ulcerative colitis or indeterminate colitis. There seems to be little value of wireless capsule endoscopy in the preoperative evaluation of these patients.

  16. Stercoral colitis mimicking appendicitis

    Directory of Open Access Journals (Sweden)

    Abdelghafour Elkoundi

    2017-02-01

    Full Text Available Abstract Background Stercoral colitis is an inflammatory process involving the colonic wall related to fecal impaction. This rare condition is associated with high morbidity-mortality. Findings We report a case of a 78-year-old woman with a history of dementia under clozapine who presented a clinical and sonographic presentation of acute appendicitis. The worsening of her clinical condition prompted us to review our diagnosis and modify our approach using the CT scan which was consistent with stercoral colitis. This report concerns an atypical presentation of this condition. Conclusions The present case highlights the ability of severe forms of fecal impaction to precipitate very rare and life-threatening complications like stercoral colitis. It also points the importance of including stercoral colitis in the differential diagnosis of acute appendicitis in altered patients under anticholenergic drugs and the critical role of the CT scan as a crucial radiologic adjunct.

    Full Text Available PURPOSE: To evaluate the effect of soluble fiber or fructooligosaccharide (FOS supplementation upon trinitrobenzene sulphonic acid (TNBS-induced colitis in rats. METHODS: 64 Wistar rats were given water, soluble fiber or FOS intragastrically during 14 days prior to colitis induction with TNBS (n=48 or rectal enema with water (n=16; control group. On the 7th or 14th day following colitis induction the rats were weighed and euthanized in order to determine the colon weight/length ratio and macroscopic and microscopic scores. RESULTS: On the 7th day following colitis induction the body weight had decreased significantly, the colon weight/length ratio had increased and macroscopic and microscopic colon lesions were observed. On the 14th day following colitis induction no difference in body weight was observed, in spite of the persistence of macroscopic and microscopic lesions and increased colon weight/length ratio. Supplementation with soluble fiber or FOS did not revert colon lesions or any of the study parameters. Supplementation with FOS, but not with fiber, was associated with increased colon weight/length ratio on the 14th day. CONCLUSION: Supplementation with soluble fiber or FOS produced no significant impact on TNBS-induced colitis in rats.OBJETIVO: Avaliar a suplementação de fibra solúvel ou frutooligossacarídeos (FOS na colite induzida por TNBS em ratos.

    Full Text Available Abstract This issue of CytoJournal contains an article on screening for anal intraepithelial neoplasia in high-risk male patients. This accompanying Editorial focuses on current understanding of this relatively new disease entity, with insights as to the potential role of screening cytopathology in the epidemiology, pathophysiology and clinical management of this HIV and HPV related anal lesion, which predominates in male patients living long-term with AIDS. Mention is made of techniques of obtaining samples, methods of preparation, and morphologic classification. Issues of anoscopic confirmation, as well as topical and surgical management are emphasized. The similarity of initial experiences in anal screening to problems encountered early in cervical cancer screening programs several decades ago, are highlighted.

    Full Text Available Obstetric anal sphincter injuries can be associated with significant short and long term consequences causing devastating impacts on the quality of lives of young, otherwise healthy women. The major consequence is anal incontinence which may be short or long term and vary in severity. The other consequences include pain, infection, dyspareunia and sexual dysfunction. This may in turn result in considerable economic burden to health care providers and patients. It also has an implication on future deliveries. Although it can never be eliminated, it can be reduced by improving practice, training and provision of high quality multidisciplinary care in order to reduce long-term morbidity. Obstetric anal sphincter injuries are also a source of litigation which can be distressing to both patients and clinicians. The aim of this review article is to explore the available evidence on epidemiology, strategies for preventions, prognosis and also how to deal with governance issues.

    Full Text Available OBJECTIVE: To review the literature for clinical data on infants with allergic or eosinophilic colitis. DATA SOURCE: MEDLINE search of all indexes was performed using the words ''colitis or procto-colitis and eosinophilic'' or ''colitis or proctocolitis and allergic'' between 1966 and February of 2013. All articles that described patients' characteristics were selected. DATA SYNTHESIS: A total of 770 articles were identified, of which 32 met the inclusion criteria. The 32 articles included a total of 314 infants. According to the available information, 61.6% of infants were male and 78.6% were younger than 6 months. Of the 314 patients, 49.0% were fed exclusively breast milk, 44.2% received cow's milk protein, and 6.8% received soy protein. Diarrheal stools were described in 28.3% of patients. Eosinophilia was found in 43.8% (115/263 of infants. Colonic or rectal biopsy showed infiltration by eosinophils (between 5 and 25 perhigh-power field in 89.3% (236/264 of patients. Most patients showed improvement with theremoval of the protein in cow's milk from their diet or the mother's diet. Allergy challenge tests with cow's milk protein were cited by 12 of the 32 articles (66 patients. CONCLUSIONS: Eosinophilic colitis occurs predominantly in the first six months of life and in males. Allergy to cow's milk was considered the main cause of eosinophilic colitis. Exclusion of cow'smilk from the diet of the lactating mother or from the infant's diet is generally an effective therapeutic measure.

    Eosinophilic colitis, which is a rare form of eosinophilic gastrointestinal diseases, occurs as primary and secondary allergic eosinophilic colitis of the gastrointestinal tract infection, inflammatory bowel disease, celiac disease, and vasculitis. The diagnosis is based on a significant amount of eosinophils in the inflammatory infiltrate of the colon wall. To analyze the clinical picture taking into account comorbidities and endoscopic picture in children with eosinophilic colitis. The test group consisted of 43 children, the average age - 12.1 years diagnosed with eosinophilic colitis (according to the Whitington scale) hospitalized in the Gastroenterology Unit, Department of Pediatrics of the Medical University of Silesia in Katowice. Testing for food allergies, celiac disease, inflammatory bowel disease, gastrointestinal diseases and parasitic diseases was performed in the group of children and the analysis concerned the intensity of eosinophilic infiltration of the colon mucosa with the severity of clinical symptoms, endoscopic picture, the presence of inflammatory bowel disease, and food allergy. Half of the tested children suffered from isolated eosinophilic colitis but the rest of them had eosinophilic infiltrate with inflammatory bowel disease more often, however, the Crohn's disease. The endoscopic image was uncharacteristic, and grade III in the Whitington scale was predominant in the histopathological examination, in most cases located in the entire large intestine. The higher level of total IgE was found in less than half of the patients and it did not correlate with the severity of eosinophilic infiltration. It was shown that the severity of eosinophilic infiltration correlated with exacerbation of clinical symptoms, endoscopic image, and the presence of inflammatory bowel disease. The higher level of antibodies of ASCA and ANCA was found in approximately 20% of the children with isolated eosinophilic colitis and 63% of children with Crohn's disease

    To determine the clinicopathologic characteristics of surgically treated ulcerative colitis (UC) patients, and to compare the characteristics of UC patients with colitis-associated cancer (CAC) to those without CAC. Clinical data on UC patients who underwent abdominal surgery from 1980 to 2013 were collected from 11 medical institutions. Data were analyzed to compare the clinical features of patients with CAC and those of patients without CAC. Among 415 UC patients, 383 (92.2%) underwent total proctocolectomy, and of these, 342 (89%) were subjected to ileal pouch-anal anastomosis. CAC was found in 47 patients (11.3%). Adenocarcinoma was found in 45 patients, and the others had either neuroendocrine carcinoma or lymphoma. Comparing the UC patients with and without CAC, the UC patients with CAC were characteristically older at the time of diagnosis, had longer disease duration, underwent frequent laparoscopic surgery, and were infrequently given preoperative steroid therapy (P UC patients experience early disease exacerbation or complications. Approximately 10% of UC patients had CAC, and UC patients with CAC had a later diagnosis, a longer disease duration, and less steroid treatment than UC patients without CAC.

    : The surgical management of ulcerative colitis has been revolutionized in recent years by the development of the ileal pouch-anal procedure. Although it is now the operation of choice for most patients, there remain several controversies. A variety of designs of ileal pouch are available each with advantages and disadvantages. The technique used to anastomose the pouch to the anal canal is also open to debate with some surgeons favoring distal mucosectomy with eradication of all disease and others choosing to perform a stapled anastomosis to achieve better functional results. The main concern for gastroenterologists, however, is the risk of development of pouchitis. The etiology, diagnosis, and treatment of this condition will also be discussed in this review as well as the more classical options for the surgical treatment of ulcerative colitis.

    Full Text Available Anal stricture or stenosis, though uncommon, is disabling condition. It affects the quality of life due to pain, bleeding and difficulty in defecation, incontinence or increased frequency. It occurs when the normally pliable anoderm is replaced with fibrotic connective tissue, leading to an abnormally tight and inelastic anal canal. Mostly it occurs secondary to trauma, iatrogeny, inflammatory diseases, radiation or neoplasia. The treatment of anal stricture is generally considered to be difficult and various methods of treatment have been suggested. It is often unresponsive to conservative medical management. The surgical procedures such as dilatations and anoplasty are associated with significant complications which make it a difficult treatment challenge. Several good treatment options are available currently. Through this case, we report and explore a new medical treatment for anal strictures with four quadrant laser sphincterotomy. Resumo: A estritura ou estenose anal, embora incomum, é problema incapacitante. Essa condição afeta a qualidade de vida por causa da dor, do sangramento e da dificuldade de defecação, de incontinência ou aumento da frequência. A estenose anal ocorre quando o anoderma, normalmente flexível, foi substituído por tecido conjuntivo fibrótico, e o resultado é um canal anal anormalmente estenosado e inelástico. Na maioria dos casos, a estenose anal ocorre secundariamente a trauma, por causa iatrogênica, por doença inflamatória, radiação ou neoplasia. Em geral, se considera que o tratamento dessa condição é tarefa difícil, tendo sido sugeridos diversos métodos de tratamento. Com frequência a estenose anal não responde ao tratamento clínico conservador. Procedimentos cirúrgicos como as dilatações ou a anoplastia estão associados a complicações significativas, implicando difícil desafio terapêutico.

    2018-02-01

    Full Text Available Background: Anal sphincter tears during vaginal delivery may result in serious sequel. Anal sphincter tears occur in approximately 2–19 % of all vaginal deliveries and are the most common precursor for faecal incontinence,1 however »occult« anal sphincter injury has been defined in 33 % of primiparous women following vaginal delivery.2 Methods: 31-year old primiparous woman received transfusion due to atony after delivery. Episiotomy, second degree perineal tear and vaginal tear were surgically corrected immediately after delivery. In the following days inability to control passing of liquid stools and flatulence together with stress urinary incontinence appeared. The complaint persisted. Ultrasound and EMG examination confirmed rupture of the external anal sphincter, which had been missed at delivery. Over a year after delivery the patient had a posterior colporraphy with surgical correction of external anal sphincter, which did not result in any clinical improve- ment. On follow-up ultrasound examination a hypoechoegenic area between the external sphincter and vaginal wall was detected. The patient was referred to The University Hos- pital in Graz, where the tear will be treated with autologous myoblast transplantation in a clinical trial. Conclusions: Treatment of a missed anal sphincter tear is complicated, expensive and unpleasant for the patient. Early detection with immediate appropriate surgical correction after delivery is most efficient, but it takes experience.

    AIM To investigate the changes in microbiota in feces of patients with ulcerative colitis (UC) and pouchitis using genomic technology. METHODS Fecal samples were obtained from UC patients with or without an ileal pouch-anal anastomosis (IPAA) procedure, as well as healthy controls. The touchdown polymerase chain reaction technique was used to amplify the whole V3 region of the 16S rRNA gene, which was transcribed from DNA extracted from fecal samples. Denaturing gradient gel electrophoresis was used to separate the amplicons. The band profiles and similarity indices were analyzed digitally. The predominant microbiota in different groups was confirmed by sequencing the 16S rRNA gene. RESULTS Microbial biodiversity in the healthy controls was significantly higher compared with the UC groups (P UC patients in remission and those in the mildly active stage, the predominant species in patients with moderately and severely active UC changed obviously. In addition, the proportion of the dominant microbiota, which was negatively correlated with the disease activity of UC (r = -6.591, P UC. Patients with pouchitis had an altered microbiota composition compared with UC patients. The microbiota from pouchitis patients was less diverse than that from severely active UC patients. Sequencing results showed that similar microbiota, such as Clostridium perfringens, were shared in both UC and pouchitis. CONCLUSION Less diverse fecal microbiota was present in patients with UC and pouchitis. Increased C. perfringens in feces suggest its role in the exacerbation of UC and pouchitis. PMID:27833384

    Full Text Available Uno de los desafíos actuales para los estudios sobre movilidad y transporte en América Latina es adoptar un enfoque multidimensional de la movilidad que trascienda la noción más estrecha de desplazamiento o viaje y que, a la vez, permita integrar este tema a la discusión más general acerca del efecto de la movilidad sobre la pobreza y la exclusión social. Este artículo aborda el desafío y propone un marco analítico que recoja la -aún incipiente en nuestra región- experiencia teórico-empírica sobre estos fenómenos. Luego de revisar la literatura y argumentar a favor de la adopción de diversos postulados, se propone el enfoque de activos y estructuras de oportunidades para el estudio de la accesibilidad. Esta es concebida como el grado de ajuste entre las estructuras de oportunidades de movilidad, y los recursos y activos con que cuentan los hogares para aprovecharlas. El esquema propuesto permite maximizar la comprensión del efecto de la movilidad sobre el bienestar y el rol del transporte público.One of the major current challenges for mobility and transport studies in Latin America is the adoption of a multidimensional approach that goes beyond the narrower notion of trip and that does not neglect a broader discussion about mobility's effect on po verty and social exclusion. This article seeks to tackle this challenge and posits an analyticalframework that takes into account the theoretical and empirical regional background on these phenomena. After reviewing existing literature and affiliating to some necessary assumptions, it proposes the assets and opportunities structures approach as a useful device to study accessibility. This concept is defined as the level of adjustment between the structures of opportunity for mobility and household's resource and assets to take advantagefrom them. I argue that thisframework is adequate in order to maximize understanding of mobility's effect on welfare and the role of public transport.

    Full Text Available Inflammatory bowel diseases (IBD, such as ulcerative colitis and Crohn's disease, are an important cause of morbidity and impact significantly on quality of life. Overall, current treatments do not sustain a long-term clinical remission and are associated with adverse effects, which highlight the need for new treatment options. Fucoidans are complex sulphated, fucose-rich polysaccharides, found in edible brown algae and are described as having multiple bioactivities including potent anti-inflammatory effects. Therefore, the therapeutic potential of two different fucoidan preparations, fucoidan-polyphenol complex (Maritech Synergy and depyrogenated fucoidan (DPF was evaluated in the dextran sulphate sodium (DSS mouse model of acute colitis. Mice were treated once daily over 7 days with fucoidans via oral (Synergy or DPF or intraperitoneal administration (DPF. Signs and severity of colitis were monitored daily before colons and spleens were collected for macroscopic evaluation, cytokine measurements and histology. Orally administered Synergy and DPF, but not intraperitoneal DPF treatment, significantly ameliorated symptoms of colitis based on retention of body weight, as well as reduced diarrhoea and faecal blood loss, compared to the untreated colitis group. Colon and spleen weight in mice treated with oral fucoidan was also significantly lower, indicating reduced inflammation and oedema. Histological examination of untreated colitis mice confirmed a massive loss of crypt architecture and goblet cells, infiltration of immune cells and oedema, while all aspects of this pathology were alleviated by oral fucoidan. Importantly, in this model, the macroscopic changes induced by oral fucoidan correlated significantly with substantially decreased production of at least 15 pro-inflammatory cytokines by the colon tissue. Overall, oral fucoidan preparations significantly reduce the inflammatory pathology associated with DSS-induced colitis and could

    We recently identified galectin-3 (gal-3) as a new and strong fibroblast activator produced by colonic epithelial cells. Very little is known about the influence of gal-3 in inflammatory bowel disease. We, therefore, investigated the impact of gal-3 on dextran sodium sulfate (DSS)-induced colitis in a mouse model. Colonic lamina propria fibroblasts of healthy controls were used for co-incubation studies of gal-3 with gal-1, TGF-β1, IFNγ, IL-4 and IL-10. Acute and chronic DSS colitis was induced by 3% DSS in drinking water in female Balb/c mice weighing 20-22 g. Recombinant gal-3 was expressed by the pET vector system and used for a 5-day treatment in different concentrations intraperitoneally. The distal third of the colon was used for histologic analysis. Colonic cytokine expression was determined by quantitative RT-PCR. In vitro, gal-3 induced IL-8 secretion was significantly reduced by co-incubation with IL-10 (5 ng/ml) and IL-4 (10 ng/ml). Acute DSS-induced colitis was ameliorated by gal-3 treatment as indicated by increased colonic length and reduced weight loss compared to that of controls. In acute and chronic colitis, gal-3 treatment resulted in a significant suppression of colonic IL-6. Gal-3 significantly reduces inflammation in acute and chronic DSS colitis in mice indicating a potential role in intestinal inflammation. © 2015 S. Karger AG, Basel.

    Computed tomography (CT) is useful for evaluating the diagnosis of gastrointestinal disease, such as infectious colitis, in patients with severe pain and bloody diarrhea. During the 7 years between November 1993 and October 2000, 34 patients with infectious colitis (18 male, 16 female; mean age 42±19 yrs), received emergency CT and colonoscopy because of severe abdominal pain and dysentery. The following organisms were isolated: pathogenic Escherichia coli (12), 6 of which were O157: H7 (O-157), Salmonella species (11), Campylobacter species (5), Vibrio parahaemolyticus (3), Yersinia enterocolotica (2) and Shigella species (1). Thickening of the intestinal wall greater than 10 mm was seen in the ascending colon in the 6 cases with E. coli O157, in 5/11 cases with Salmonella, 4/5 with Campylobacter and 1/6 with non-O157 pathogenic E. Coli. marked intestinal wall thickening, greater than 20 mm, was seen in the ascending colon of the 4 of the patients with an O-157 infection. In all patients with O-157 colitis, slight ascites was noted in the pelvic space. In additions, ascites was also seen in 3/13 patients with Salmonella and 1/5 patients with Campylobacter colitis. The CT findings, in the patients with infectious colitis, are non-specific but knowledge and recognition of the findings will help in patient evaluation and proper treatment. (author)

    Restorative proctocolectomy with ileo-pouch-anal anastomosis is the standard procedure for ulcerative colitis. It provides complete removal of the diseased colorectum, avoids permanent ileostomy and allows the preservation of continence. Functional results and quality of life after restorative proctocolectomy are of great importance. Patients usually have 5-6 bowel movements per day, and continence is satisfactory in more than 90% of patients. A good pouch function strongly correlates with high quality of life. Postoperative septic complications are the main risk factor for bad pouch function and pouch failure; therefore nowadays most procedures are performed with a covering ileostomy. Quality of life is usually impaired by active ulcerative colitis, and restorative proctocolectomy improves the quality of life up to the level of a healthy reference population. Taken together, restorative proctocolectomy provides excellent results concerning function and quality of life.

    The results of 16 cases of restorative proctocolectomy with J-pouch and ileoanal anastomosis performed for ulcerative colitis, associated with polyposis in one, and for diffuse polyposis in the last one, are reported. Satisfactory functional results as for continence, number of daily bowel movements and with moderate nocturnal leakage in a single patient, were obtained. The anal sphincter function, assessed manometrically about one year after surgery was shown to be normal in all cases except for the loss of sphincteric and inhibitory reflex. In spite of the still debated problems, it is concluded that this procedure based on the absence of operative mortality, acceptable morbidity and satisfactory long-term results, is the treatment of choice in surgery of ulcerative colitis with severe rectal lesions or dysplasia and of familial polyposis with carpeting rectum and/or cancer.

    To evaluate the radiologic findings of granulomatous colitis on double contrast barium enema and changes on follow-up studies. Serial double contrast barium enema of six patients with granulomatous colitis confirmed by endoscopic biopsy were reviewed. We analyzed the radiologic findings and their follow-up changes, including aphthous ulcers, lymphoid hyperplasia, deep ulcers, cobble stone appearance, geographic ulcers, asymmetric involvement of ulcers, skip lesions, sinus tract, fistula formation, pseudosacculation, focal stricture, and small bowel involvement. Pretreatment double contrast barium enema findings were aphthous ulcers in five patients, deep ulcer in six, cobble stone appearance in five, longitudinal geographic ulcers in two, fistulas in one, pseudosacculations in two, focal stricture in one, and pseudopolyps in six. Also, anal ulcers were observed in two patients, asymmetric involvement of ulcers in three, skip lesions in four, and small bowel involvement in five in five patients proved to have inactive disease after treatment, aphthous ulcers and deep ulcers disappeared. Geographic ulcers of two patients and anal ulcer of one patients decreased in size or depth. Pseudosacculation in one patient disappeared. Pseudopolyps decreased in two patients, increased in one, and decreased after increase in two. One patient whose disease remained active after treatment showed maintenance or increase of ulcers or fistula. And their pseudosacculation or focal stricture unchanged and pseudopolyps decreased. The major radiologic findings of chronic granulomatous colitis on double contrast barium enema are aphthous ulcer, deep ulcer, cobble stone appearance, discontinuity of the lesion and coexistence of ulcers and pseudopolyps. And, double contrast barium enema is good follow-up modality because its findings correlate with clinical course of the granulomatous colitis after treatment

    Autoimmune hepatitis is a rare, chronic inflammatory disorder which has been associated with a number of other auto-immune conditions. However, there are no reports in the medical literature of an association with microscopic (lymphocytic) colitis. We report the case of a 53-year-old woman with several autoimmune conditions, including lymphocytic colitis, who presented with an acute hepatitis. On the basis of the clinical features, serology, and histopathology, we diagnosed autoimmune hepatitis. To our knowledge, this is the first report of autoimmune hepatitis in association with lymphocytic colitis, and lends support to the theory of an autoimmune etiology for lymphocytic colitis.

  11. Dietary Salt Exacerbates Experimental Colitis.

    The Western diet is characterized by high protein, sugar, fat, and low fiber intake, and is widely believed to contribute to the incidence and pathogenesis of inflammatory bowel disease (IBD). However, high sodium chloride salt content, a defining feature of processed foods, has not been considered as a possible environmental factor that might drive IBD. We set out to bridge this gap. We examined murine models of colitis on either a high salt diet (HSD) or a low salt diet. We demonstrate that an HSD exacerbates inflammatory pathology in the IL-10-deficient murine model of colitis relative to mice fed a low salt diet. This was correlated with enhanced expression of numerous proinflammatory cytokines. Surprisingly, sodium accumulated in the colons of mice on an HSD, suggesting a direct effect of salt within the colon. Similar to the IL-10-deficient model, an HSD also enhanced cytokine expression during infection by Salmonella typhimurium This occurred in the first 3 d of infection, suggesting that an HSD potentiates an innate immune response. Indeed, in cultured dendritic cells we found that high salt media potentiates cytokine expression downstream of TLR4 activation via p38 MAPK and SGK1. A third common colitis model, administration of dextran sodium sulfate, was hopelessly confounded by the high sodium content of the dextran sodium sulfate. Our results raise the possibility that high dietary salt is an environmental factor that drives increased inflammation in IBD. Copyright © 2017 by The American Association of Immunologists, Inc.

    Full Text Available A method is developed for the analysis of sterols together with triterpenic alcohols (erythrodiol and uvaol in vegetable oils. The method involves obtention of the unsaponifiable matter, isocratic HPLC separation with refractive index detector, preparation of silylderivatives, and analysis by capillary GC. Four procedures involving GC analysis of sterol and sterol+dialcohol fractions obtained by HPLC and CCF separations are compared. A collaborative trial comparing HPLC-sterols+dialcohols and CCF-sterols (official methods is carried out. For Δ7-sterols, higher values and better repeatability and reproducibility were observed in the first method, but no differences for the remainder sterols were found. The erythrodiol+uvaol determinations by HPLC-sterols+dialcohols and CCF-sterols+dialcohols (official methods resulted in similar precision.

    Full Text Available Nitric oxide (NO is thought to play an important role in modulating the inflammatory response by virtue of its ability to affect bloodflow, leukocyte function and cell viability. The objective of this study was to assess the role that NO may play in mediating the mucosal injury and inflammation in a model of chronic granulomatous colitis using two pharmacologically different inhibitors of nitric oxide synthase (NOS. Chronic granulomatous colitis with liver and spleen inflammation was induced in female Lewis rats via the subserosal (intramural injection of peptidoglycan/polysaccharide (PG/PS derived from group A streptococci. Chronic NOS inhibition by oral administration of NG-nitro-L-arginine methyl ester (L-NAME (15 µmol/kg/day or amino-guanidine (AG (15 µmol/ kg/day was found to attenuate the PG/PS-induced increases in macroscopic colonic inflammation scores and colonic myeloperoxidase activity. Only AG -- not L-NAME – attenuated the PG/PS-induced increases in colon dry weight. Both L-NAME and AG significantly attenuated the PG/PS-induced increases in spleen weight whereas neither was effective at significantly attenuating the PG/PS-induced increases in liver weight. Although both L-NAME and AG inhibited NO production in vivo, as measured by decreases in plasma nitrite and nitrate levels, only AG produced significantly lower values (38±3 versus 83±8 µM, respectively, P<0.05. Finally, L-NAME, but not AG, administration significantly increased mean arterial pressure from 83 mmHg in colitic animals to 105 mmHg in the PG/PS+ L-NAME-treated animals (P<0.05. It is concluded that NO may play an important role in mediating some of the pathophysiology associated with this model of chronic granulomatous colitis.

    Full Text Available Este artigo tem como objetivo investigar, na obra de Freud, a demarcação que se institui entre o terapêutico e o analítico. Tal investigação enfoca, primeiramente, a passagem da hipnose à associação livre e o direcionamento do autor à questão da causa, o que estabelece uma visada para a cura analítica em confluência com o que se desdobra da exploração do campo do inconsciente e da consideração de um domínio pulsional. Delimitados por esta via os objetivos terapêuticos e analíticos, interroga-se, em seguida, como a dimensão do terapêutico se veria reintroduzida nos termos da nova direção de cura proposta por Freud.

    Full Text Available An 18-year-old female with ankylosing spondylitis developed fever, abdominal pain and diarrhea on two occasions after starting sulphasalazine therapy. Flexible sigmoidoscopy revealed pseudomembranous colitis; fecal cultures were positive for Clostridium difficile; and C difficile toxin assay was positive. Despite the frequent use of sulphasalazine in the management of inflammatory bowel disease, this complication has been apparently rare. Clinicians should be wary of the onset of diarrhea in patients receiving sulphasalazine, whether for inflammatory bowel disease or other conditions.

    In patients diagnosed with anal fistula, knowing the quality of life specifically related to the disease can help coloproctology specialists to choose the most appropriate therapeutic strategy for each case. The aim of our study is to analyzse and describe the factors related to the specific quality of life in a consecutive series of patients diagnosed with anal fistula. Observational, cross-sectional study carried out from March 2015 to February 2017. All patients were assessed in the colorectal surgery unit of a hospital in southeast of Spain. After performing an initial anamnesis and a physical examination, patients diagnosed with anal fistula completed the Quality of Life in Ppatients with Anal Fistula Questionnaire (QoLAF-Q). This questionnaire specifically measures quality of life in people with anal fistula and its score range is the following: zero impact = 14 points, limited impact = 15 to 28 points, moderate impact = 29 to 42 points, high impact = 43 to 56 points, and very high impact = 57 to 70 points. A total of 80 patients were included. The median score obtained in the questionnaire for the sample studied was 34.00 (range=14-68). Statistically significant differences between patients with "primary anal fistula" (n=65) and "recurrent anal fistula" (n=15) were observed (mean rank=42.96 vs. mean rank=29.83, p=0.048). Furthermore, an inverse proportion (P=.016) between "time with clinical symptoms" and "impact on quality of life" was found (5 years: mean rank = 19.00). There were no statistically significant differences (P=.149) between quality of life amongst patients diagnosed with complex (mean rank = 36.13) and simple fistulae (mean rank = 43.59). Anal fistulae exert moderate-high impact on patients' quality of life. "Shorter time experiencing clinical symptoms" and the "presence of primary fistula" are factors that can be associated with worse quality of life. Copyright © 2018 AEC.

    2014-01-01

    This review summarizes diagnostic problems, challenges and advances in ulcerative colitis (UC). It emphasizes that, although histopathological examination plays a major role in the diagnosis and management of UC, it should always be interpreted in the context of clinical, endoscopic, and radiological findings. Accurate diagnosis requires knowledge of the classic morphological features of UC, as well as a number of atypical pathological presentations that may cause mis-classification of the disease process, either in resection or biopsy specimens. These atypical pathological presentations include rectal sparing and patchiness of disease at initial presentation of UC in pediatric patients or in the setting of medically treated UC, cecal or ascending colon inflammation in left-sided UC, and backwash ileitis in patients with severe ulcerative pancolitis. Loosely formed microgranulomas, with pale foamy histiocytes adjacent to a damaged crypt or eroded surface, should not be interpreted as evidence of Crohn’s disease. Indeterminate colitis should only be used in colectomy specimens as a provisional pathological diagnosis. Patients with UC are at risk for the development of dysplasia and carcinoma; optimal outcomes in UC surveillance programs require familiarity with the diagnostic criteria and challenges relating to UC-associated dysplasia and malignancy. Colon biopsy from UC patients should always be evaluated for dysplasia based on cytological and architectural abnormalities. Accurate interpretation and classification of dysplasia in colon biopsy from UC patients as sporadic adenoma or UC-related dysplasia [flat, adenoma-like, or dysplasia-associated lesion or mass (DALM)] requires clinical and endoscopic correlation. Isolated polypoid dysplastic lesions are considered to be sporadic adenoma if occurring outside areas of histologically proven colitis, or adenoma-like dysplasia if occurring in the diseased segment. Recent data suggest that such lesions may be treated

    There is a close relationship between the human host and the intestinal microbiota, which is an assortment of microorganisms, protecting the intestine against colonization by exogenous pathogens. Moreover, the intestinal microbiota play a critical role in providing nutrition and the modulation of host immune homeostasis. Recent reports indicate that some strains of intestinal bacteria are responsible for intestinal ulceration and chronic inflammation in inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) and Crohn's disease (CD). Understanding the interaction of the intestinal microbiota with pathogens and the human host might provide new strategies treating patients with IBD. This review focuses on the important role that the intestinal microbiota plays in maintaining innate immunity in the pathogenesis and etiology of UC and discusses new antibiotic therapies targeting the intestinal microbiota.

    We discuss the newest evidence-based data on management of ulcerative colitis (UC). We emphasize risk-stratification, optimizing medical therapies, and surgical outcomes of UC. Recent medical advances include introduction of novel agents for UC. Vedolizumab, an anti-adhesion molecule, has demonstrated efficacy in moderate to severe UC. Tofacitinib, a small molecule, has also demonstrated efficacy. Data on optimization of infliximab show the superiority of combination therapy with azathioprine over monotherapy with infliximab or azathioprine alone. Data on anti-tumor necrosis factor-alpha (anti-TNF) therapeutic drug monitoring also hold promise, as do preliminary data on the dose escalation of infliximab in severe hospitalized UC. Surgical outcome data are reassuring, with new fertility data showing the effectiveness of in vitro fertilization. UC management is multi-disciplinary and changing. While novel therapies hold promise, better optimization of our current arsenal will also improve outcomes.

    Ulcerative colitis is a chronic inflammatory disease, characterized by diffuse mucosal inflammation in the colon. Adalimumab, as a TNF-α blocker, offers a safe and efficacious treatment option for patients with moderate to severe ulcerative colitis and refractory or intolerant to conventional medications; however, its cost-effectiveness profile has not yet been well established. Future economic evaluations should choose appropriate comparators in the context of target-reimbursement decision making and focus on cost-effectiveness over a long time horizon.

Until recently, the official compendia professed the microbiological trial for dosing this antibiotic, method considered as non-feasible in the routine of quality control centers due to the excessive time for release of results. Aiming at obtaining an alternative method for dosing nystatin vaginal cream, a chromatographic method (HPLC was developed and validated. The method developed used a reversible phase column of C18, 3.9 x 150 mm, 4 mm, at 30 ºC. The mobile phase was made up of a 0.25 mM sodium phosphate buffer and 0.025 mM EDTA, pH 6.00, methanol and acetonitrile (40:30:30, rate of

    Full Text Available A trombose é uma doença caracterizada por eventos de hipercoagulabilidade. A terapêutica anticoagulante oral com antagonistas da vitamina K (AVKs é amplamente indicada para prevenção e/ou controle de distúrbios da coagulação. O manuseio de administração dos AVKs é difícil devido à complexidade da definição da dose. Em geral, o monitoramento de indivíduos submetidos à terapêutica com AVK é realizado pela determinação do tempo de protrombina, em que se avalia o grau de anticoagulação através do coeficiente internacional normatizado. Invariavelmente, o fluxo do processamento laboratorial, que compreende as fases pré-analítica, analítica e pós-analítica, é importante para a fidedignidade dos resultados, repercutindo na conduta médica de forma determinante. O objetivo deste estudo foi a realização de uma revisão da literatura científica descritiva utilizando bases de dados eletrônicos para busca de materiais científicos, como Google Scholar, MEDLINE, LILACS, PubMed, SciELO e Science Direct. Abordamos alguns aspectos relacionados ao fluxo analítico da monitoração laboratorial em um laboratório de análises clínicas. Em conclusão, é necessária uma apropriada condução das fases analíticas para que seja possível o sucesso terapêutico com uso dos AVKs.

    Background. Allergy to cow milk protein is a common cause of gastrointestinal symptoms in infancy. Milk allergy is usually a clinical diagnosis, and thus there have been few reports of the radiographic findings. Objective. To describe the barium enema findings of allergic colitis and differentiate them from Hirschsprung disease. Materials and methods. Four infants (age range 7 days-5 weeks) with constipation underwent barium enema to exclude Hirschsprung disease. Radiographic findings were correlated with the pathologic specimens from suction rectal biopsy. Results. All enemas revealed irregular narrowing of the rectum and a transition zone. Rectal biopsies in each case demonstrated ganglion cells and evidence of an allergic colitis, with inflammatory infiltrates in the lamina propria. A diagnosis of milk allergy colitis was made and symptoms resolved after removal of milk from the diet. Conclusions. Milk allergy is common in infancy. The rectum is a primary target organ, with allergic colitis often diagnosed on clinical grounds alone. However, a child with allergic colitis may be referred to radiology for barium enema, especially if constipation is present. The radiologist should be aware of the unique imaging findings of allergic colitis, so as to avoid confusion with Hirschsprung disease and perhaps an unnecessary rectal biopsy. (orig.)

    Full Text Available Questões relacionadas à assertividade têm recebido atenção por parte de terapeutas comportamentais há mais de três décadas. É mais recente, porém, o esforço de terapeutas analítico-comportamentais para examinar problemas dessa ordem com os mesmos recursos conceituais e metodológicos empregados por seus pares da pesquisa básica e conceitual. O presente trabalho tem como objetivo oferecer uma interpretação analítico-comportamental para padrões de comportamento assertivos, agressivos e passivos. Recuperamos algumas definições de assertividade/agressividade/passividade e examinamos os fenômenos correspondentes enquanto relações comportamentais; discutimos alguns aspectos da abordagem analítico-comportamental para o autocontrole; e sugerimos que as relações comportamentais definidas como assertividade/agressividade/passividade podem ser interpretadas enquanto instâncias de autocontrole ou impulsividade. A abordagem pode abrir novas perspectivas de investigação clínica de habilidades sociais sob um enfoque analítico-comportamental.

    Full Text Available Background: On an average 30-50% of patients who undergo incision and drainage (I and D of anal abscess will develop recurrence or fistula formation. It is claimed that finding the internal orifice of anal abscess to distract the corresponding anal gland duct; will decline the rate of future anal fistula. Surgeons supporting I and D alone claim that finding the internal opening is hazardous. This study is conducted to assess short-term results of optional method to manage patients with anal abscess and fitula-in-ano at the same time. Materials and Methods: In this cross-sectional descriptive study 49 from 77 patients with anal abscess whose internal orifice was not identified by pressing on the abscess, diluted hydrogen peroxide (2% and methylene blue was injected into the abscess cavity and the anal canal was inspected to find out the internal opening. Once the opening was distinguished, an incision was given from the anal verge to the internal opening. Results: The internal orifice was identified in 44 out of 49 patients (90% who underwent this new technique. Up to 18 months during follow-up, only 2.5% of patients with primary fistulotomy developed fistula on the site of a previous abscess. Conclusion: Conventional method to seek the internal orifice of anal abscesses is successful in about one-third of cases. By applying this new technique, surgeons would properly find the internal opening in >90% of patients. Needless to say, safe identification of the anal gland orifice in anal abscess disease best helps surgeons to do primary fistulotomy and in turn it would significantly decrease the rate of recurrence in anal abscess and fistula formation.

    Sleep deprivation (SD) is an epidemic phenomenon in modern countries, and its harmful effects are well known. SD acts as an aggravating factor in inflammatory bowel disease. Melatonin is a sleep-related neurohormone, also known to have antioxidant and anti-inflammatory effects in the gastrointestinal tract; however, the effects of melatonin on colitis have been poorly characterized. Thus, in this study, we assessed the measurable effects of SD on experimental colitis and the protective effects of melatonin. For this purpose, male imprinting control region (ICR) mice (n = 24) were used; the mice were divided into 4 experimental groups as follows: the control, colitis, colitis with SD and colitis with SD and melatonin groups. Colitis was induced by the administration of 5% dextran sulfate sodium (DSS) in the drinking water for 6 days. The mice were sleep-deprived for 3 days. Changes in body weight, histological analyses of colon tissues and the expression levels of pro-inflammatory cytokines and genes were evaluated. SD aggravated inflammation and these effects were reversed by melatonin in the mice with colitis. In addition, weight loss in the mice with colitis with SD was significantly reduced by the injection of melatonin. Treatment with melatonin led to high survival rates in the mice, in spite of colitis with SD. The levels of pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, IL-17, interferon-γ and tumor necrosis factor-α, in the serum of mice were significantly increased by SD and reduced by melatonin treatment. The melatonin-treated group showed a histological improvement of inflammation. Upon gene analysis, the expression of the inflammatory genes, protein kinase Cζ (PKCζ) and calmodulin 3 (CALM3), was increased by SD, and the levels decreased following treatment with melatonin. The expression levels of the apoptosis-related inducible nitric oxide synthase (iNOS) and wingless-type MMTV integration site family, member 5A (Wnt5a) genes was

    Surgery for ulcerative colitis is a major and complex colorectal surgery. Laparoscopy benefits these patients with better outcomes in context of cosmesis, pain and early recovery, especially in young patients. For surgeons, it is a better tool for improving vision and magnification in deep cavities. This is not the simple extension of the laparoscopy training. Starting from preoperative preparation to post operative care there are wide variations as compared to open surgery. There are also many variations in steps of laparoscopic surgery. It involves left colon, right colon and rectal mobilisation, low division of rectum, pouch creation and anastomosis of pouch to rectum. Over many years after standardisation of this technique, it takes same operative time as open surgery at our centre. So we present our standardized technique of laparoscopic assisted restorative proctocolectomy and ileal pouch anal anastomosis (IPAA). PMID:26195886

    Pouchitis in ileal anal anastomosis represents an important clinical complication after restorative proctocolectomy. Acute and chronic inflammation of the reservoir is a frequent event sometimes associated with villous atrophy and colonic metaplasia. After ileal pouch anastomosis, twenty-one patients affected by ulcerative colitis were studied. An image analyzer CAS 200 (Becton Dickinson) was utilized to evaluate the DNA intranuclear content in every biopsy. In two cases abnormal DNA distribution was observed, and in one case a poliploid pattern was seen. Abnormal DNA distribution was also present in colonic metaplasia. Therefore, image analysis for the detection of DNA aneuploidy may be of additional value together with histologic parameters in follow up, in order to exclude transformation of the ileal mucosa in neoplastic epithelia.

    2018-02-01

    Full Text Available Background: Anal incontinence severely impairs quality of life. It affects 4 to 19 % of women and is statistically related to number of vaginal deliveries. It is grossly underreported and most patients that do seek help are referred to gastroenterologists or colorectal surgeons. Incidence of recognized sphincter injuries at time of delivery is 1 to 2 %. However studies with anal ultrasound showed incidence of anal sphincter injuries at 28 to 41 %. Depending on the degree of injury symptoms range from partial to complete inability to control passing of winds, liquid or solid stools. About three thirds of patients are asymp- tomatic in puerperium, however half of them are at risk of developing anal incontinence in later life. Hypoestrogenisem, additional perineal trauma during consequent deliveries and sphincter atrophy can unmask anal sphincter damage years later. Timely recognition and treatment are vital for good long term results and quality of life, if possible immediately after delivery. Good knowledge of perineal anatomy, recognition of risk factors, intense search and appropriate treatment and follow-up are essential to management of anal sphincter injuries. All secondary sphincter repair is less effective. Content: Updated overview of current opinion and guidelines on anal sphincter injuries are pre- sented. Anal sphincter is composed of external anal sphincter (EAS and internal anal sphincter (IAS. Striated EAS is divided into three parts – subcutaneous, superficial, deep, and con- nected to puborectalis muscle posteriorly. Smooth-muscled IAS is a continuation of a cir- cular smooth-muscle layer of rectum. In between there is a thin longitudinal muscle layer. IAS constitutes 70 % of resting tone and is under constant contraction. EAS contributes to 30 % of resting tone and almost all pressure during active contraction. EAS injury leads to insufficient contraction after rectal sampling and filling which causes urgency – patient can

    Full Text Available Primary sclerosing cholangitis and Ulcerative colitis are caused by progressive inflammation of the bile duct and large intestine respectively. The existence of any plausible association between Primary sclerosing cholangitis and Ulcerative colitis remains highly elusive. Little is known about the incidence and prevalence of primary sclerosing cholangitis with concomitant Ulcerative colitis in the Indian subcontinent. We report a case of Primary sclerosing cholangitis with long standing Ulcerative colitis which later also developed Primary biliary cirrhosis.

    Full Text Available Elisabeth Lippert, Martina Müller, Claudia Ott University Hospital Regensburg, Department of Internal Medicine I, Regensburg, Germany Abstract: Ulcerative colitis (UC is a chronic inflammation mainly affecting the colon mucosa. It predominantly occurs in younger patients. Until recently, the main goals in the treatment of UC were to temper the symptoms, such as diarrhea, pain, and weight loss, by using mesalazine and steroids. With newer medications, such as immunomodulators (thiopurines and the biologics providing blockade of tumor necrosis factor (TNF, the goals of the therapy in UC have changed to long-term remission and mucosal healing. The first available anti-TNF therapy in UC included infusion therapy with infliximab every few weeks. In 2012, subcutaneously administered adalimumab gained approval for the treatment of UC in Germany. In patients with a mild disease, therapy with mesalazine, orally or topically, can be sufficient. In patients with moderate to severe disease, therapy with azathioprine or anti-TNF is often required to reach disease control; however, this is only efficient in about two-thirds of patients. Some patients either show no response or a lost response while on treatment. So, further medical options are warranted in the treatment of UC. With golimumab, a new approach in the treatment of mild to moderate UC recently became available in Germany and is a promising new option in the therapy regimen for patients with UC.

    Background and purpose: The aim of this study was to define the effects of voluntary anal contraction on prostate motion in an experimental setting. Materials and methods: Thirty-eight patients (median age, 76 years) with prostate cancer underwent thin-slice computed tomography (CT) in the vicinity of the prostate before and after active anal contraction. Three-dimensional displacement of the pelvis and prostate was measured. Results: Mean (±standard deviation, SD) overall displacement of the prostate due to anal contraction was 0.3 ± 1.4 mm to the right, 9.3 ± 7.8 mm to the anterior, and 5 ± 4 mm to the cranial direction. Mean displacement of the pelvis was 0.5 ± 1.8 mm to the right, 4.1 ± 7.1 mm to the anterior, and 1 ± 3 mm to the cranial direction. Mean displacement of the prostate relative to the pelvis was 0.1 ± 1.1 mm to the left, 5.2 ± 3.3 mm to the anterior, and 4 ± 4 mm to the cranial direction. Conclusions: Voluntary anal contraction within an experimental setting induces large prostate and bone motion, mainly in the anterior and cranial directions. The frequency and magnitude of actual anal contractions during radiotherapy for prostate cancer need to be determined.

    Full Text Available Diffuse amyloid goiter (AG is an entity characterized by the deposition of amyloid in the thyroid gland. AG may be associated with either primary or secondary amyloidosis. Secondary amyloidosis is rarely caused by inflammatory bowel diseases. Secondary amyloidosis is relatively more common in the patients with Crohn’s disease, whereas it is highly rare in patients with ulcerative colitis. Diffuse amyloid goiter caused by ulcerative colitis is also a rare condition. In the presence of amyloid in the thyroid gland, medullary thyroid cancer should be kept in mind in the differential diagnosis. Imaging techniques and biochemical tests are not very helpful in the diagnosis of secondary amyloid goiter and the definitive diagnosis is established based on the histopathologic analysis and histochemical staining techniques. In this report, we present a 35-year-old male patient with diffuse amyloid goiter caused by secondary amyloidosis associated with ulcerative colitis.

    Patients with extensive ulcerative colitis (UC) of more than eight years duration have an increased risk of colorectal cancer. Molecular biomarkers for dysplasia and cancer could have a great clinical value in managing cancer risk in these UC patients. Using a wide range of molecular techniques - including cutting-edge OMICS technologies - recent studies have identified clinically relevant biomarker candidates from a variety of biosamples, including colonic biopsies, blood, stool, and urine. While the challenge remains to validate these candidate biomarkers in multi-center studies and with larger patient cohorts, it is certain that accurate biomarkers of colitis-associated neoplasia would improve clinical management of neoplastic risk in UC patients. This review highlights the ongoing avenues of research in biomarker development for colitis-associated colorectal cancer. PMID:27672285

    Full Text Available La confección de presupuestos públicos austeros para la consecución de los criterios de convergencia impuestos por el Tratado de Maastricht ha originado una preocupación en todo el Sector Público en general, y en el hospitalario en particular, por la contención de los costes. Esta situación ha puesto de manifiesto la necesidad de introducir sistemas de Contabilidad para la Gestión interna de las organizaciones hospitalarias públicas. Así, la Contabilidad Analítica o de Costes se constituye como un componente más de dichos sistemas y está llamada a alcanzar dos objetivos muy claros, por un lado, la determinación del coste del producto hospitalario para en base a él realizar una presupuestación prospectiva, y por otro, suministrar información interna que permita llevar a cabo un verdadero Control de Gestión. Con este trabajo se pretenden describir los modelos de costes alternativos propuestos por la literatura especializada, señalando su idoneidad en base a la consecución de los objetivos que la Contabilidad Analítica debe satisfacer. Se pondrá de manifiesto la tendencia actual a establecer modelos basados en la nueva definición de producto hospitalario, los cuales tienen como finalidad la determinación de los costes totales de dicho producto, dejando a un lado el objetivo del control de la eficacia y eficiencia de la gestión.The development of strict Public Budgets in order to reach the goals settled by Maastricht agreements have caused a deep concern in the Public Sector and mostly in hospitals in order to brake the growth of costs.

    Bile acid absorption was investigated using 75 Se Taurohomocholate (SeHCAT) in controls and patients who had undergone total colectomy with either conventional ileostomy or pouch-anal anastomosis for ulcerative colitis or adenomatous polyposis. Whole-body retention of SeHCAT after 168 hours was greater in the controls than the patients who had undergone colectomy (P less than .05). Retention of SeHCAT did not differ significantly between patients with an ileostomy and patients with pouch-anal anastomosis, but patients with an ileostomy and ileal resection of more than 20 cm retained less SeHCAT than patients with a pouch-anal anastomosis (P less than .01). Analysis of fecal bile acids from ileostomies and pouches showed that bacterial metabolism of primary conjugated bile acids was greater in patients with a pouch. It was concluded that bile acid absorption was not significantly impaired by construction of a pouch compared with conventional ileostomy, but bacterial metabolism of bile acids was greater in the pouches

    ABSTRACT Patients with inflammatory bowel disease are often deficient in micronutrients such as selenium and have an increased risk of colon cancer. We tested whether the selenium transport protein, selenoprotein P, could modify colitis-associated cancer. Our results indicate that global SEPP1 haploinsufficiency augments tumorigenesis and mediates oxidative damage in the intestine. PMID:27314080

    Since 1979, 3,115 stool samples were tested for detection of Clostridium difficile and its cytotoxin; these were obtained from patients who had drug-related diarrhea. Presumed or proven colitis due to C. difficile was diagnosed in 130 patients. Drugs implicated most commonly as causing or associated with the onset of enterocolitis due to C. difficile were ampicillin (38 episodes), cephalosporins (71), clindamycin (36), and the aminoglycosides (45). The hamster model of colitis was employed to explore the role of other inducing agents. Altering the usual diet of hamsters to one with a higher protein content decreased the time to death due to C. difficile cecitis following the administration of cefazolin (10 mg). Several cathartics also were studied for their effect on the lethality of antibiotic-induced cecitis. Daily administrations of castor oil (0.5 ml per day) and vegetable oil (1.0 ml per day) improved survival against lethal doses of clindamycin. Milk of magnesia or mineral oil provided no protection. Four patients with C. difficile colitis induced by therapy with cytotoxic drugs also were identified. Methotrexate induced cecitis when administered orally and daily to hamsters, and C. difficile and its cytotoxin were identified in the hamsters' stools. Death due to methotrexate-induced cecitis was prevented by daily administration of folinic acid or vancomycin. These data demonstrate that a variety of antibiotics, antineoplastic agents, cathartics, and diet changes can induce C. difficile colitis in humans and hamsters.

    The aim of the present study was to study microscopic colitis (MC) in children with special reference to its role in chronic diarrhea and changes in mucosal biopsies. A total of 100 consecutive children ages 3 to 12 years, with nonbloody diarrhea (passage of ≥3 loose stools per day) of >12 weeks' duration were screened and 26 were enrolled in the study in which no specific etiology could be found and colonoscopy did not reveal any mucosal abnormality. Colonic biopsies were evaluated for the presence of lymphocytic colitis or collagenous colitis and those with the characteristic changes were defined to have MC (group A). Colonic biopsies from patients with MC were compared with biopsies from patients with chronic diarrhea but no evidence of MC (group B). One hundred children ages 3 to 12 years with bleeding per rectum were screened and colonic biopsies from 45 patients (group C) who had colonic mucosal changes but no vascular or polyp lesion were compared with patients with MC. Of the 26 patients with chronic diarrhea, MC was found in 5 (3 lymphocytic colitis and 2 collagenous colitis). Significantly higher polymorphonuclear infiltration was seen in group A as compared with group B (13.8 [5.4-20.6] vs 7.2 [0-19.6]; P = 0.03) or group C (13.8 [5.4-20.6] vs 4 [0-13.4]; P = 0.007). Intraepithelial lymphocytes (12 [4-32] vs 4 [0-24]; P = 0.008) and basement membrane thickening (3.5 [2.9-10.6] vs 2.5 [1.6-5.86]; P = 0.008) were also significantly higher in group A as compared with group C. MC was found to be present in children with nonbloody chronic diarrhea in children. Further multicentric studies may provide adequate data on its prevalence.

    Ulcerative colitis (UC) is an inflammatory destructive disease of the large intestine occurred usually in the rectum and lower part of the colon as well as the entire colon. In this paper, the influence of IL-1α and IL-4 on the experimental ulcerative colitis by light emitting diode ( LED ) (λ: 632.8nm; power: 4.0mw) applied to colon directly were studied. Making 30 rats into 3 groups: LED curative group, model group, normal control group. There were 10 rats of each group. We used glacial acetic acid (5%) and trinitro-benzene-sulfonic acid (TNBS) (1%) intra-anally to replicate the rat model of ulcerative colitis. After a week treatment with administrating LED rectal irradiation to curative group, 30mm each time, once per day, the histopathological studies in colonic tissue were performed, and the expression and distribution of IL-lα and IL-4 in colonic tissues were investigated by immunohistochemical staining. The extent of the Colonic tissue injury in LED curative group was not as significant as that in the model group. Compared with model group, the content of MDA in LED curative group was reductived and the activity of SOD was increased significantly, and the expression and distribution of IL-lα in LED curative group was depressed significantly, however the expression and distribution of IL-4 in LED curative group was increased obviously. This results show that the LED rectal irradiation can protect colonic mucosa from the experimental ulcerative colitis in rats, and suggest that the effects may be related to the photobiomodulation and immunomodulation of LED.

    Full Text Available The objective of this study was to evaluate the consensus of expert societies and published guidelines on the management of ulcerative colitis, and to compare with the experience of the authors, in order to standardize procedures that would help the reasoning and decision-making process of the physician. A search was performed in scientific literature, specifically in electronic databases: Medline/Pubmed, SciELO, EMBASE and Cochrane, and the following descriptors were used: ulcerative colitis, acute colitis, clinical treatment, surgery and randomized trial. It can be concluded that the goals of therapy in ulcerative colitis are clinical and endoscopic remission, deep, sustained remission without corticosteroids, prevention of hospitalizations and surgeries, and improved quality of life. The surgical indications are reserved for selected cases, ranging from medical intractability, complications (severe refractory acute colitis, toxic megacolon, perforation and hemorrhage and malignancy.

Em todas realizamos manometria anal e as seguintes medidas: a pressão anal máxima em repouso (basal; b pressão anal ao esforço de contração; c pressão anal ao esforço de evacuação. Os resultados das manometrias, analisados por métodos de estatística, mostraram que na gestação a pressão anal de repouso diminui; a pressão anal ao esforço de contração não se altera; as diferenças registradas mantêm-se no curso da primigestação. Concluímos que as pressões anais são modificadas pela gestação, em primigestas.Pregnancy is followed by physiological digestive system adaptations.

    The aetiopathogenesis of chronic anal fissure (CAF) is unclear and is probably multifactorial. CAF represents 10-15% of proctological consultations. This case report identifies adulthood sexual abuse as a significant risk and a potential aetiopathogenic factor of CAF This case history was discovered while carrying out administrated interviews during authors' clinical retrospective study on CAF. The clinical presentation of this 49-year-old woman is predominated by chronic anal lesions (anal tears in the anoderm, anal sphincter hypertrophy), associated medical history as a high consumer of healthcare with very poor mental health, chronic traumatic anal sex practice history, and especially persistent recurrences of gastro-intestinal symptoms after surgery. Surgical history is summarized as: 7x spontaneous abortion; 5x fistulectomy and 3x anal abscess; 4x Bartholin's gland; 4x hypertrophy papilla ablation; 2x anal manometry, 2x fissurectomy and 1x sphincterotomy; 2x haemorrhoid; and 1x hysterectomy. These symptoms initially started and the operations in particular took place after she was married. After 26 years of sexual abuse within her marriage, the clinical diagnosis was made and was consented by this patient. A referral to a psychiatrist was evident and a long course of multidisciplinary therapy (medical, surgical, physiological and psychological approaches) seemed to be of benefit, in terms of improving the clinical symptoms. Authors suggest that physicians should suspect sexual abuse in any patient with a medical history as a high consumer of healthcare and especially when there is persistent recurrence after the lateral subcutaneous internal sphincterotomy. We recognise that the link or causality is difficult to prove and further study is probably needed to shed light on the link between sexual abuse and CAF: although in the United Kingdom, over 20.83% of the population are subject to sexual abuse. 83%.

    2012-01-31

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    The aim of this study was to systematically review the findings of publications addressing the epidemiology of anal human papillomavirus (HPV) infection, anal intraepithelial neoplasia, and anal cancer in women. We conducted a systematic review among publications published from Jan. 1, 1997, to Sept. 30, 2013, to limit to publications from the combined antiretroviral therapy era. Three searches were performed of the National Library of Medicine PubMed database using the following search terms: women and anal HPV, women anal intraepithelial neoplasia, and women and anal cancer. Publications were included in the review if they addressed any of the following outcomes: (1) prevalence, incidence, or clearance of anal HPV infection, (2) prevalence of anal cytological or histological neoplastic abnormalities, or (3) incidence or risk of anal cancer. Thirty-seven publications addressing anal HPV infection and anal cytology remained after applying selection criteria, and 23 anal cancer publications met the selection criteria. Among HIV-positive women, the prevalence of high-risk (HR)-HPV in the anus was 16-85%. Among HIV-negative women, the prevalence of anal HR-HPV infection ranged from 4% to 86%. The prevalence of anal HR-HPV in HIV-negative women with HPV-related pathology of the vulva, vagina, and cervix compared with women with no known HPV-related pathology, varied from 23% to 86% and from 5% to 22%, respectively. Histological anal high-grade squamous intraepithelial lesions (anal intraepithelial neoplasia 2 or greater) was found in 3-26% of the women living with HIV, 0-9% among women with lower genital tract pathology, and 0-3% for women who are HIV negative without known lower genital tract pathology. The incidence of anal cancer among HIV-infected women ranged from 3.9 to 30 per 100,000. Among women with a history of cervical cancer or cervical intraepithelial neoplasia 3, the incidence rates of anal cancer ranged from 0.8 to 63.8 per 100,000 person-years, and in

    2017-12-01

    Chronic colitis, regardless of type, is defined histologically by chronic inflammation, mainly plasmacytosis, in the lamina propria. Specific diagnosis of chronic colitides in biopsies can be challenging for practicing pathologists. This article focuses on discussing specific histologic features in biopsies of the inflammatory bowel diseases (IBDs), including ulcerative colitis, Crohn colitis, and colitis of indeterminate type. It also offers suggestions as to how to separate the IBDs from other chronic colitides, such as lymphocytic colitis, collagenous colitis, diverticular disease-associated colitis, diversion colitis, and chronic colitides that are due to drugs. Normal histology in colon biopsies is also briefly discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    We report a 41-year-old woman who developed histology- and colonoscopy-proven ischemic colitis with the use of naratriptan not exceeding the maximum 2 doses a day and 3 days per week and without a known medical or cardiovascular history. By exclusion of other causes of colonic ischemia, naratriptan was considered the sole causal agent. Discontinuation of naratriptan resulted in a complete clinical recovery. To date, our patient is the youngest known patient to develop ischemic colitis on isolated naratriptan in the setting of no known medical risk factors or predisposing medical condition. Even though triptans are commonly used for the abortive treatment of migraine headaches, such a reported side effect is rare; however, careful assessment and individual patient-based treatment is advised.

    To determine adiponectin expression in colonic tissue of murine colitis and systemic cytokine expression after melatonin treatments and sleep deprivation. The following five groups of C57BL/6 mice were used in this study: (1) group I, control; (2) group II, 2% DSS induced colitis for 7 d; (3) group III, 2% DSS induced colitis and melatonin treatment; (4) group IV, 2% DSS induced colitis with sleep deprivation (SD) using specially designed and modified multiple platform water baths; and (5) group V, 2% DSS induced colitis with SD and melatonin treatment. Melatonin (10 mg/kg) or saline was intraperitoneally injected daily to mice for 4 d. The body weight was monitored daily. The degree of colitis was evaluated histologically after sacrificing the mice. Immunohistochemical staining and Western blot analysis was performed using anti-adiponectin antibody. After sampling by intracardiac punctures, levels of serum cytokines were measured by ELISA. Sleep deprivation in water bath exacerbated DSS induced colitis and worsened weight loss. Melatonin injection not only alleviated the severity of mucosal injury, but also helped survival during stressful condition. The expression level of adiponectin in mucosa was decreased in colitis, with the lowest level observed in colitis combined with sleep deprivation. Melatonin injection significantly (P sleep deprivation.

    Full Text Available Although classically pseudomembranous colitis is caused by Clostridium difficile, it can result from several etiologies. Certain medications, chemical injury, collagenous colitis, inflammatory bowel disease, ischemia, and other infectious pathogens can reportedly cause mucosal injury and subsequent pseudomembrane formation. We present the case of a middle-aged woman with vascular disease who was incorrectly diagnosed with refractory C. difficile infection due to the presence of pseudomembranes. Further imaging, endoscopy, and careful histopathology review revealed chronic ischemia as the cause of her pseudomembranous colitis and diarrhea. This case highlights the need for gastroenterologists to consider non-C. difficile etiologies when diagnosing pseudomembranous colitis.

    Necrotizing colitis associated with carcinoma of the colon, known also as obstructive colitis, is a disorder characterized by anulceration and inflammation of the colon proximal to an obstructive lesion, especially carcinoma of the rectosigmoid colon, and in rare instance, leads to acute gangrene of the colon. The authors analyzed radiologic findings in four cases of necrotizing colitis associated with carcinoma of the colon. Barium enema disclosed mucosal edema, nodular filling defects, irregularity of the colonic contour and typical thumbprinting appearance of involved colon proximal to an obstructing carcinoma of the colon. The mechanism of necrotizing colitis was briefly reviewed

    1984-01-01

    The development of a Pulse Height Analizer is described. This equipment is essential to analize data coming from detectors producing information codified in pulse amplitudes. The system developed consist of a Signal Input Module connected to a Controller Module based on a 8085A microprocessor capable to memorize pulses up to 1 uS in 256 channels with a resolution better than 20 mV. A Communication Module with a serial interface is used for data transfer to a host computer using RS232c protocol. The Monitoring and Operation Module consist of a hexadecimal Keybord, a 6 digit 7-segment display and a XY analog output enabling real time visualization of data on a XY monitor. The hardware and the software designed for this low cost system were optimized to obtain a typical dead time of approximately 100 uS. As application, this device was used to adquire curves at the Small Angle X-ray Scattering Laboratory in this Department. The apparatus performance was tested by comparing its data with a Northern Pulse Height Analizer model NS633 output, with favorable results. (Author) [pt

  19. Anal intraepitelial neoplasia: a narrative review

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Anal intraepitelial neoplasia (AIN constitutes a major health problem in certain risk groups, such as patients with immunosuppression of varied origin, males who have sexual relations with other males, and females with a previous history of vaginal or cervical abnormalities in cytology. Its relationship with the human papillomavirus (HPV infection has been well documented; however, many of the factors involved in the progression and regression of the viral infection to dysplasia and anal carcinoma are unknown. AIN can be diagnosed through cytology of the anal canal or biopsy guided by high-resolution anoscopy. However, the need for these techniques in high-risk groups remains controversial. Treatment depends on the risk factors and given the high morbidity and high recurrence rates the utility of the different local treatments is still a subject of debate. Surgical biopsy is justified only in the case of progression suggesting lesions. The role of the vaccination in high-risk patients as primary prevention has been debated by different groups. However, there is no general consensus on its use or on the need for screening this population.

    To search the pathophysiological mechanism of diarrhea based on daily stool weights, fecal electrolytes, osmotic gap and pH. Seventy-six patients were included: 51 with microscopic colitis (MC) (40 with lymphocytic colitis (LC); 11 with collagenous colitis (CC)); 7 with MC without diarrhea and 18 as a control group (CG). They collected stool for 3 d. Sodium and potassium concentration were determined by flame photometry and chloride concentration by titration method of Schales. Fecal osmotic gap was calculated from the difference of osmolarity of fecal fluid and double sum of sodium and potassium concentration. Fecal fluid sodium concentration was significantly increased in LC 58.11+/-5.38 mmol/L (Pdiarrhea compared to fecal osmotic gap. Seven (13.3%) patients had osmotic diarrhea. Diarrhea in MC mostly belongs to the secretory type. The major pathophysiological mechanism in LC could be explained by a decrease of active sodium absorption. In CC, decreased Cl/HCO3 exchange rate and increased chloride secretion are coexistent pathways.

    Cytomegalovirus (CMV) infection has been shown to be related to severe or steroid-refractory ulcerative colitis (UC) flare-ups. The aim of this study was to evaluate the endoscopic and pathological characteristics of CMV colitis in patients with UC and to assess the predictive value of the endoscopic and pathological features of CMV colitis. A total of 50 consecutive UC patients with CMV infection who were admitted to Peking Union Medical College Hospital from 2010 to 2015 were enrolled in this study. Twenty-five UC patients with CMV infection (50.0%) had concurrent CMV colitis. When the cutoff value was set at 1150 copies, the sensitivity and specificity of blood CMV DNAq polymerase chain reaction for predicting CMV colitis were 44.4% and 78.9%, respectively. A higher proportion of endoscopic punched-out ulcers, irregular ulcers, and cobblestone-like appearance were observed among the patients in the CMV colitis group than those in the non-CMV colitis group (52.0% versus 20.0%, 60.0% versus 16.0%, and 20.0% versus 0%, respectively, P colitis group than in the control group (68.0% versus 44.0%). Characteristic endoscopic features with punch-out ulcers and high CMV viremia load may be useful for predicting the presence of CMV colitis in histology. Punch-out ulcers were found to be associated with a higher number of inclusion bodies on histology, suggesting a role of targeted biopsy for endoscopist.

  9. Long-Term Natural History and Complications of Collagenous Colitis

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Microscopic forms of colitis have been described, including collagenous colitis, a possibly heterogeneous disorder. Collagenous colitis most often appears to have an entirely benign clinical course that usually responds to limited treatment. Sometimes significant extracolonic disorders, especially arthritis, spondylitis, thyroiditis and skin disorders, such as pyoderma gangrenosum, dominate the clinical course and influence the treatment strategy. However, rare fatalities have been reported and several complications, some severe, have been attributed directly to the colitis. Toxic colitis and toxic megacolon may develop. Concomitant gastric and small intestinal inflammatory disorders have been described including celiac disease and more extensive collagenous inflammatory disease. Colonic ulceration has been associated with the use of nonsteroidal anti-inflammatory drugs, while other forms of inflammatory bowel disease, including ulcerative colitis and Crohn disease, may evolve directly from collagenous colitis. Submucosal ‘dissection’, colonic fractures, or mucosal tears and perforation, possibly from air insufflation during colonoscopy, have been reported. Similar changes may result from increased intraluminal pressures that may occur during radiological imaging of the colon. Neoplastic disorders of the colon may also occur during the course of collagenous colitis, including colon carcinoma and neuroendocrine tumours (ie, carcinoids. Finally, lymphoproliferative disease has been reported.

    Amebic colitis was common disease in Korea as well as in the world especially frequent in tropical area such as Africa, India and South America. Clinicopathological forms of this condition were ulcerative rectocolitis (95%), typhloappendicitis (3%), ameboma (1.5%), and fulminating colitis with toxic megacolon (0.5%). The fulminating amebic colitis with toxic megacolon was very rare and dangerous condition which was reported by Wruble on 1966. Toxic megacolon was seen in the cases of ulcerative colitis, Crohn's disease, typhoid fever, cholera, and acute bacillary dysentery. Radiological findings of fulminating amebic colitis with toxic megacolon were megacolon, multiple polypoid filling defects, thumbprinting, and cobble stone appearance, which were resemble with ulcerative colitis. The cause of toxic megacolon was not well known, but it has been speculated that this results from transmural disease with destruction of muscle and the myenteric plexus with resultant loss of muscle tone. Authors experienced a case of fulminating amebic colitis with toxic megacolon which was resemble with ulcerative colitis by radiologically at Kyung Hee University Hospital and reported it with review of the literatures.

    Few studies have reported minimally invasive total proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). We herein report a novel hand-assisted hybrid laparoscopic-robotic technique for patients with FAP and UC. Between February 2010 and March 2014, six patients underwent hand-assisted hybrid laparoscopic-robotic total proctocolectomy with IPAA. The abdominal colectomy was performed laparoscopically with hand assistance through a transverse suprapubic incision, also used to fashion the ileal pouch. The proctectomy was carried out with the da Vinci Surgical System. The IPAA was hand-sewn through a trans-anal approach. The procedure was complemented by a temporary diverting loop ileostomy. The mean hand-assisted laparoscopic surgery (HALS) time was 154.6 (±12.8) min whereas the mean robotic time was 93.6 (±8.1) min. In all cases, a nerve-sparing proctectomy was performed, and no conversion to traditional laparotomy was required. The mean postoperative hospital stay was 13.2 (±7.4) days. No anastomotic leakage was observed. To date, no autonomic neurological disorders have been observed with a mean of 5.8 (±1.3) bowel movements per day. The hand-assisted hybrid laparoscopic-robotic approach to total proctocolectomy with IPAA has not been previously described. Our report shows the feasibility of this hybrid approach, which surpasses most of the limitations of pure laparoscopic and robotic techniques. Further experience is necessary to refine the technique and fully assess its potential advantages.

Se utilizó un ecógrafo ALOKA ProSound SSD-4000 al que se conectó un transductor radial multifrecuencia ASU-67 (7,5 y 10 MHz. Resultados: un paciente no toleró la exploración. En 8 pacientes (20% de los casos estudiados se detectaron alteraciones en el estudio ecográfico: en 4 pacientes, 10% de los casos (1 hombre y 3 mujeres, hipertrofia del esfínter anal interno (EAI y en 5 pacientes (4 mujeres y 1 hombre rotura del complejo esfinteriano. En una mujer se observó rotura de EAI en canal alto e hipertrofia del mismo en el canal medio. Conclusiones: la ecografía rectoanal es una prueba sencilla, económica y útil para el estudio de la patología rectoanal. Si bien, en la mayoría de los casos estudiados no se han detectado lesiones en el canal anal ni en la pared rectal, en un porcentaje no desdeñable de pacientes hemos observado engrosamiento del EAI, que podría considerarse posible causa del dolor anal. Por tanto, consideramos que la ecografía rectoanal debe ser incluida en el estudio del dolor anal crónico idiopático.

    One of the most serious complications of ulcerative colitis is the development of colorectal cancer. Screening patients with ulcerative colitis by standard histological examination of random intestinal biopsy samples might be inefficient as a method of cancer surveillance. This Review focuses...... on the current understanding of the pathogenesis of ulcerative colitis-associated colorectal cancer and how this knowledge can be transferred into patient management to assist clinicians and pathologists in identifying patients with ulcerative colitis who have an increased risk of colorectal cancer.

    Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening

São descritos os aspectos clínicos e o tratamento dos pacientes com câncer escamoso desta região. Casuística - Analisaram-se, retrospectivamente, 11 pacientes com carcinoma espinocelular de canal anal. Nove pacientes eram do sexo feminino e dois do masculino. A idade média dos pacientes foi de 57,6 anos (variação 35-82 anos. Resultados - Os sintomas mais freqüentes foram sangramento retal, tumoração e dor local. Seis pacientes tinham lesão benigna prévia local e dois tinham doença metastática na ocasião do diagnóstico. Todos foram submetidos a quimioterapia sistêmica com 5-fluorouracil e mitomicina. Após o tratamento quimio e radioterápico, quatro apresentavam doença residual e foram submetidos a ressecção abdômino-perineal. Três pacientes apresentaram recidiva e quatro morreram pela evolução da própria doença. Conclusão - A maioria dos doentes era do sexo feminino. A químio e a radioterapia podem ser tratamentos curativos nos pacientes com doença localizada; no entanto, aqueles com doença residual devem ser submetidos a ressecção abdômino-perineal.

    Full Text Available INTRODUÇÃO: A retocele é causa comum de constipação por defecação obstruída. Freqüentemente está relacionada com outras causas de defecação obstruída, e os exames de fisiologia anal são importantes para o diagnóstico preciso da causa de constipação intestinal. OBJETIVO: observar a influência da retocele nos exames de fisiologia anal, e a necessidade da realização desses após o diagnóstico da retocele. MÉTODO: Para este trabalho foram estudados 40 pacientes com diagnóstico de defecação obstruída. Todos os pacientes foram submetidos aos exames de manometria, sensibilidade retal, eletromiografia, latência do nervo pudendo e proctografia, e foram separados em 2 grupos: portadores e não portadores de retocele . Foram encontrados 18 pacientes com retocele, e o diagnóstico mais freqüentemente associado foi o anismus . Em relação aos exames foi encontrada diferença significante apenas na proctografia no ângulo ano retal, demonstrando que a presença de retocele não interferiu nos resultados de exames de fisiologia anal quando comparados com outros constipados, mas esteve associada a outras causas de constipação, como anismus que necessita de outro tipo de tratamento. CONCLUSÃO: A retocele não interferiu nos valores dos exames de fisiologia anal, mas esteve associada a outros diagnósticos, sendo importante a realização dos mesmos.INTRODUCTION: Rectocele is a common cause of constipation for obstructed defecation.

    Anaerobic bacteria constitute more than 90% of the bacteria in the colon. An anaerobic environment is needed to maintain their growth and the production of short-chain fatty acids by these bacteria from carbohydrates. Short-chain fatty acids are rapidly absorbed and essential for metabolic as well as functional welfare of the colonic mucosa. The importance of these acids in water absorption and in the patogenesis of colitis is discussed in relation to the concept of "energy deficiency diseases" of the colonic mucosa.

    Full Text Available The prognosis of malignant peritoneal mesothelioma is extremely poor with a mean survival time of 12 months. The initial symptoms are poor and atypical. Because of its rare entity and little knowledge of its treatments, there are few reports of long-term survival. We encountered a very unique case with strong impression on radiological findings of malignant peritoneal methothelioma. We had misdiagnosed it because of the findings and because the time course was similar to that of ischemic colitis. The radiological findings on CT and enema disappeared within one week after antibiotic therapy.

    Inflammatory pouch complications refractory to first-line therapies remain problematic following ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). We evaluated infliximab efficacy and associations with therapeutic response. Data from individuals who underwent colectomy and IPAA for UC (2000-2014) were reviewed. Patients with chronic refractory pouchitis (CP) and Crohn's disease (CD)-like outcomes treated with infliximab were included. Pre-treatment parameters and response at median 8 (initial) and 48 weeks (sustained) were measured. Complete response was defined as symptomatic and endoscopic resolution with modified Pouchitis Disease Activity Index (mPDAI) 2. Serum was analysed for Anti-Saccharomyces cerevisiae antibodies (ASCA), anti-OmpC, anti-CBir1 and perinuclear Anti-Neutrophil Cytoplasmic Antibodies (pANCA). One hundred and fifty-two patients with CP or a CD-like phenotype were identified. Forty-two were treated with infliximab (33% male; age 32.6±2.6 years, 28.5% CD-like). Post-induction response was achieved in 74% (48% complete) and sustained response in 62.6% (29.6% complete). Mean mPDAI and C-reactive protein declined from 8.5±0.3 to 2±3.4 (p infliximab use (p Infliximab can effectively treat inflammatory pouch complications.

    To assess the effect of vaginal delivery and caesarean section on faecal symptoms and structure and function of anal sphincter in women who sustained obstetric anal sphincter injuries (OASIS) in their previous pregnancy and were advised about the mode of delivery based on faecal incontinence symptoms, anal manometry and endoanal ultrasound. It is a descriptive study on a cohort of women who had OASIS from 2006 to 2013. They were assessed after OASIS and during subsequent pregnancy with a questionnaire, endoanal ultrasound and anal manometry. Vaginal delivery was recommended to asymptomatic women with normal investigations. Elective caesarean section was recommended to women with faecal symptoms, anal sphincter defects of more than 30° or low resting or incremental anal pressures. All women were reassessed after subsequent delivery. Fifty women who had pregnancies after OASIS, were seen after OASIS, during subsequent pregnancy and after the second delivery. 15 women had faecal symptoms after OASIS. The external, internal and combined anal sphincter defects were seen in 13, 11 and 9 women respectively. Low resting and incremental pressure were seen in 15 and 11 women respectively. Caesarean section was done in 22 women and 28 women delivered vaginally. Worsening of faecal symptoms and reduction in anal pressures were not observed in planned vaginal delivery or elective caesarean section groups. Faecal symptoms were worse with reduced anal pressures in three women from the planned caesarean section group. One of the women had a vaginal delivery and two women had emergency caesarean section at 7cm and 10cm dilatation. There were no new sphincter defects or recurrent OASIS in any of the women in the study group. Decision about the mode of delivery of pregnancy after OASIS based on symptoms, anal manometry and endoanal ultrasound helps in preserving the anal sphincter function and avoiding unnecessary caesarean sections. Further follow-up of these patients is essential

    Microscopic colitis includes lymphocytic colitis and collagenous colitis. The entity is considered as an important cause for unknown chronic diarrhea, but rarely reported in China before. This study aimed to determine the prevalence of microscopic colitis in patients with chronic diarrhea and normal colonoscopy findings in Southern China, and to reveal the clinical feature of microscopic colitis in these patients. Patients with chronic diarrhea and normal colonoscopic findings were enrolled from three hospitals in Southern China from January, 2009 to June, 2010. Multiple colorectal biopsies were obtained in these patients and histological examination was underwent with hematoxyin and eosin stain, Masson's trichrome stain and immunohistochemistry for tenascin to screen lymphocytic colitis and collagenous colitis. The clinical symptom and risk factor of microscopic colitis were assessed by comparing with controls. The diagnostic overlap between microscopic colitis and irritable bowel syndrome or functional diarrhea was also analyzed. Randomly mucosal biopsies were performed in 613 patients with chronic diarrhea and normal or near normal colonoscopic finding. Fifty-nine cases of lymphocytic colitis and 28 cases of collagenous colitis were found by histological examination. The rates of rheumatoid arthritis in lymphocytic colitis group (15.4 %) and collagenous colitis group (14.3 %) were significant higher than in control group (2.2 %). Rheumatoid arthritis was confirmed as the risk factor of microscopic colitis by logistic regression analysis. There was no difference on the symptoms among the controls, patients with lymphocytic colitis, and patients with collagenous colitis. There were 13.8 % (12/87) of patients with microscopic colitis fulfilled Rome III criteria of irritable bowel syndrome and 42.5 % (37/87) fulfilled the criteria of functional diarrhea. Microscopic colitis is not an uncommon disorder in Chinese population. Rheumatoid arthritis is the risk factor of

    Chronic idiopathic anal pain (CIAP) remains a diagnosis of exclusion. Its study and management still lack a standardized protocol. The aim of this study is to evaluate the results obtained with the diagnostic-therapeutic protocol established in our service. We performed a retrospective study of patients diagnosed with CIAP at the Colorectal Unit of the General University Hospital of Elche, between 2005 and 2011. We evaluated 57 patients with a diagnosis of chronic anal pain for functional anorectal disease (FAD). After the application of our diagnostic protocol, final diagnosis of chronic anal pain (CAP) was achieved in 43 cases (75%), including 22 cases of descending perineum syndrome, 12 of proctalgia fugax, 2 of pudendal neuritis and 7 of coccydynia. In 14 patients exclusion diagnosis of CIAP was established. Among the therapies used on patients with CIAP, biofeedback combined with conservative measures improved symptoms in 43% of the cases. Sacral nerve stimulation was assessed in patients who did not respond to other treatments. Through proper anamnesis, physical examination and complementary tests, a specific diagnosis of the cause of CAP by FAD can be achieved, reducing exclusion diagnosis of CIAP to 25% of cases. Conservative measures combined with biofeedback achieved an improvement in pain in more than 40% of the cases of CIAP in our study. Sacral nerve stimulation can be considered as a treatment option in refractory cases. Copyright © 2013 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

Infliximab and adalimumab are powerful agents that are used for remission induction and maintenance therapy in UC and have an acceptable safety profile. However, a proportion of UC patients for whom therapy with anti-TNF agents is indicated fail or become intolerant to treatment with infliximab or adalimumab. Hence, there remains an unmet need for novel anti-TNF agents. Golimumab (Simponi®, a human anti-TNF antibody that is administered by monthly subcutaneous injections, is the most recently introduced TNF blocker for the treatment of UC. Here, we will discuss recent literature on clinical efficacy and safety of golimumab induction and maintenance treatment in patients with UC. Furthermore, we will discuss the positioning of golimumab for UC in current treatment algorithms. Keywords: ulcerative colitis, UC, antitumor necrosis factor, TNF, antibodies, golimumab

    Constipation is a common complaint seen in the emergency department for which patients will try many different remedies. This case report discusses the outcome of a patient who developed a chemical colitis after using a hydrogen peroxide enema to relieve his constipation. A 43-year-old male with a history of chronic constipation presented to the Emergency Department (ED) with complaints of abdominal pain and hematochezia after self-administering a commercial sodium phosphate/sodium biphosphate enema mixed with hydrogen peroxide. The patient began to have left-sided abdominal cramping pain afterwards. He also began to have bowel movements mixed with bright red blood every 30 minutes. An abdominal computed tomography scan showed moderate to severe bowel wall thickening consistent with colitis involving the rectum extending to the distal one-third of the transverse colon. The patient was admitted to the internal medicine service for further monitoring. Gastroenterology was consulted for further management. The abdominal pain and hematochezia resolved and the patient was discharged the next day without complications.

  17. Management and treatment of distal ulcerative colitis

    Full Text Available Ulcerative colitis (UC is a chronic inflammatory condition that is confined to the colonic mucosa. Its main symptoms include diarrhea, rectal bleeding and abdominal pain. Approximately two-thirds of UC patients have disease confined distal to the splenic flexure, which can be treated effectively with topical therapy. This means the active drug can be delivered directly to the site of inflammation, limiting the systemic absorption and potential side effects. Topical treatment with aminosalicylates is the most effective approach in the treatment of these forms, provided that the formulation reaches the upper margin of the disease. Given this, the suppository formulation is the treatment of choice for proctitis and distal sigmoiditis. Thanks to their proximal spread, enemas, foams and gels represent the treatment of choice for proctosigmoiditis and for distal ulcerative colitis. Oral aminosalicylates are less effective than topical therapies in patients with active disease, while the combination of topical and oral treatment is more effective in patients refractory to topical or oral mono-therapy. Topically administered aminosalicylates play an important role in the maintenance of remission, but the long-term adhesion to therapy is poor. For this reason, the oral formulation is the first-line therapy in the maintenance of remission. Refractory patients can be treated with topical steroids or systemic steroids and TNF-alpha inhibitors in severe forms.

  18. Inverse Association Between Helicobacter pylori Gastritis and Microscopic Colitis.

    Inflammatory bowel disease is known to be inversely associated with Helicobacter pylori infection of the upper gastrointestinal tract. We hypothesized that a similar inverse association also applied to microscopic colitis. The associations between microscopic colitis and presence of H. pylori-positive chronic active gastritis (CAG), H. pylori-negative CAG, intestinal metaplasia, or gastric atrophy were expressed as odds ratios with their 95% confidence intervals. Multivariate logistic regression analyses were used to adjust these associations for sex, age, percentage residents per ZIP code with white, black, Hispanic, or Asian ethnicity, percentage with college education, average housing values, annual income, and population size of individual ZIP codes. H. pylori-positive CAG was less common among patients with than without microscopic colitis (odds ratio = 0.61; 95% confidence interval, 0.52-0.70). Intestinal metaplasia also occurred less frequently among patients with than without microscopic colitis (0.75, 0.65-0.86). These inverse associations remained unaffected by adjustments for parameters of ethnicity and socioeconomic status. In contradistinction with H. pylori-positive CAG, H. pylori-negative CAG was more common in patients with than without microscopic colitis (1.54, 1.17-1.97). H. pylori infection and microscopic colitis are inversely associated. This observation is consistent with similar inverse associations found between H. pylori and inflammatory bowel disease. These relationships may provide clues about the yet unknown etiology of microscopic colitis.

    The diagnostic yield in open access endoscopy has been evaluated which generally support the effectiveness and efficiency of open access endoscopy. With a few exceptions, diagnostic yield studies have not been performed in open access endoscopy for more specific conditions. Therefore, we conducted a study to determine the efficiency of open access endoscopy in the detection of microscopic colitis as compared to traditional referral via a gastroenterologist. A retrospective search of the pathology database at the University of Missouri for specimens from a local open access endoscopy center was conducted via SNOMED code using the terms: "microscopic", "lymphocytic", "collagenous", "spirochetosis", "focal active colitis", "melanosis coli" and "histopathologic" in the diagnosis line for the time period between January 1, 2004 and May 25, 2006. Specimens and colonoscopy reports were reviewed by a single pathologist. Of 266 consecutive patients with chronic diarrhea and normal colonoscopies, the number of patients with microscopic disease are as follows: Lymphocytic colitis (n = 12, 4.5%), collagenous colitis (n = 17, 6.4%), focal active colitis (n = 15, 5.6%), and spirochetosis (n = 2, 0.4%). The diagnostic yield of microscopic colitis in this study of an open access endoscopy center does not differ significantly from that seen in major medical centers. In terms of diagnostic yield, open access endoscopy appears to be as effective in diagnosing microscopic colitis.

    Anal metastasis from colorectal cancer rarely occurs, but it severely impairs the patient's quality of life, often requiring wide resection including the anal sphincter with permanent colostomy. This lesion can be misdiagnosed as a perianal fistula or an abscess, and it can be overlooked at the time of surgery because it is not included in the routine surgical extent of low anterior resection. We report two rare cases of anal metastasis from colorectal cancer. In both cases, perianal nodules with an internal solid portion were detected on preoperative rectal magnetic resonance imaging and additional local excisions of the anal lesions were performed during the process of treatment. Anal metastasis was pathologically confirmed by histology and immunohistochemical staining.

    Budesonide is the treatment of choice for microscopic colitis because of its excellent risk to benefit ratio. It is a potent, well-absorbed corticosteroid, but because of a high rate of first-pass metabolism in the liver, its systemic bioavailability is low. It has fewer corticosteroid-related adverse effects than prednisone, and adrenal suppression is considered to be rare. We present a middle-aged woman with lymphocytic colitis whose symptoms responded to budesonide but developed budesonide-related iatrogenic Cushing's syndrome. Withdrawal of budesonide led to restoration of normal pituitary-adrenal responsiveness but at the price of recurrent diarrhea due to re-emergence of lymphocytic colitis.

  13. Severe ischemic colitis following olanzapine use: a Case Report

    Samuel Raimundo Fernandes

    Full Text Available Ischemic colitis is the most common subtype of intestinal ischemia usually resulting from vasospasm, vessel occlusion or mesenteric hypoperfusion. Neuroleptics have seldom been linked to ischemic colitis by blocking peripheral anticholinergic and antiserotonergic receptors inducing severe gastrointestinal paresis. We report a young patient with severe ischemic colitis requiring surgery due to necrosis of the bowel. After exclusion of other potential causes, olanzapine was admitted as the cause of ischemia. Clinicians should be aware of how to recognize and treat the potentially life-threatening effects of neuroleptics.

No obstante el conocimiento de la extensión precisa de la enfermedad tiene gran importancia en las decisiones terapéuticas a tomar y también en el pronóstico de la enfermedad. Por todo ello, la validación de una técnica no invasiva para el estudio de extensión de la colitis ulcerosa cobra gran interés e importancia. Material y método: se incluyen en el estudio pacientes con diagnóstico previo de colitis ulcerosa o en el debut de la enfermedad y, de forma prospectiva y ciega se evalúa la precisión de la ecografía digestiva en la valoración de la extensión de la colitis ulcerosa. Las exploraciones ecográficas son realizadas todas ellas por el mismo explorador y siempre con anterioridad al estudio endoscópico completo, que se usa como patrón oro. No se emplea la técnica hidrocolónica en ningún caso. Resultados: han sido incluidos en el estudio 20 pacientes, 13 varones (65% y 7 mujeres (35%, con una edad media de 51,7 años (rango de 24 a 82 años. Los estudios endoscópicos mostraron una afectación severa en 5 casos (25%, moderada en 12 pacientes (60% y lesiones leves en los 3 casos restantes (15%. El estudio ecográfico del colon fue considerado satisfactorio en 18 casos (90% y la extensión de la enfermedad establecida en el estudio ecográfico coincide en todos los casos con la determinada por la colonoscopia: 3 pacientes (16,6% presentaban una proctitis ulcerosa, 9 (50% una colitis izquierda y 6 (33,3% una colitis extensa. Conclusiones: la ecografía digestiva permite el estudio del marco colónico en la mayoría de los pacientes, especialmente si existe actividad inflamatoria, permitiendo establecer con gran precisión la extensión de la colitis ulcerosa, independientemente del grado de actividad de la misma.Introduction: a full examination of the colon

    Full Text Available O Papilomavírus humano (HPV é o agente sexualmente transmissível mais comum na região perianal. O vírus provoca lesões clínicas e subclínicas que podem evoluir para carcinoma anal. É descrito o aumento da incidência desse tipo de tumor naqueles que praticam sexo anal; nos portadores, de ambos os sexos, de lesões genitais HPV induzidas; nas pessoas com neoplasias intraepiteliais anais de alto grau, o precursor do carcinoma, com maior incidência nos infectados pelo vírus da imunodeficiência humana (HIV, e com outras causas de supressão imunológica. Outra característica das lesões HPV induzidas é a elevada incidência de recidivas. Daí, a importância do seguimento por longo prazo e da pesquisa de meios terapêuticos para reduzir essa ocorrência. A possibilidade da detecção das lesões precursoras indica que programas padronizados de rastreamento para a prevenção do câncer anal deveriam ser instituídos. Os esfregaços anais para citologia vêm sendo realizados, com eficácia semelhante a das coletas cervicais e a colposcopia anal tem sido indicada para biópsias dirigidas quando a citologia mostrou-se alterada, embora muitos recomendam-na, também, como método de rastreamento. Nesse artigo, descrevemos a padronização da coleta de material para citologia anal e o método de realização da colposcopia anal, bem como a periodicidade com que devem ser repetidos.The human papillomavirus is the most frequent sexually transmitted agent in anorectal area. This virus provokes clinical and sub-clinical lesions that can evolve to anal carcinoma. Its incidence is increasing among those who practice anal receptive sex; in both gender patients with genital HPV induced lesions; in those with high grade anal intra-epithelial neoplasia, anal carcinoma precursor, mainly among HIV infected persons or with other causes of immunodeficiency. Another HPV induced lesions characteristic is their elevated incidence of recurrences. Therefore

    Colorectal cancer is a worldwide cancer with rising annual incidence. Inflammation is a well-known cause of colorectal cancer carcinogenesis. Metabolic inflammation (metaflammation) and altered gut microbiota (dysbiosis) have contributed to colorectal cancer. Chemoprevention is an important strategy to reduce cancer-related mortality. Recently, various polypharmacologic molecules that dually inhibit histone deacetylases (HDAC) and other therapeutic targets have been developed. Prevention for colitis was examined by dextran sodium sulfate (DSS) mouse models. Prevention for colorectal cancer was examined by azoxymethane/dextran sodium sulfate (AOM/DSS) mouse models. Immunohistochemical staining was utilized to analyze the infiltration of macrophages and neutrophils and COX-II expression in mouse tissue specimens. The endotoxin activity was evaluated by Endotoxin Activity Assay Kit. We synthesized a statin hydroxamate that simultaneously inhibited HDAC and 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR). Its preventive effect on colitis and colitis-associated colorectal cancer in mouse models was examined. Oral administration of this statin hydroxamate could prevent acute inflammation in the DSS-induced colitis and AOM/DSS-induced colorectal cancer with superior activity than the combination of lovastatin and SAHA. It also reduced proinflammatory cytokines, chemokines, expression of COX-II, and cyclin D1 in inflammation and tumor tissues, as well as decreasing the infiltration of macrophages and neutrophils in tumor-surrounding regions. Stemness of colorectal cancer and the release of endotoxin in AOM/DSS mouse models were also attenuated by this small molecule. This study demonstrates that the polypharmacological HDAC inhibitor has promising effect on the chemoprevention of colorectal cancer, and serum endotoxin level might serve as a potential biomarker for its chemoprevention.

    Colitis is exacerbated in patients with concurrent cytomegalovirus (CMV) infection and inflammatory bowel disease (IBD). We assessed the prevalence and clinical features of CMV colitis in hospitalized IBD patients. A retrospective study reviewed the data from January 1, 1998 through December 31, 2013 compiled at the National Taiwan University Hospital. The CMV colitis patients' demographic data, clinical information, treatment regimens, pathologic findings, and outcome were analyzed. A total of 673 IBD patients were hospitalized during the study period. There were 312 patients diagnosed with Crohn's disease (CD) and 361 with ulcerative colitis (UC). CMV colitis was diagnosed as having positive inclusion bodies in colonic tissue. Six of the 312 CD patients (1.9%) and five of the 361 UC patients (1.4%) were diagnosed with CMV colitis. Compared to CD patients without CMV colitis, patients with CMV colitis were more often older (p colitis flare-ups after the index admission. The prevalence of CMV colitis in hospitalized IBD inpatients was 1.6% in Taiwan. Two associated factors for CMV colitis in hospitalized IBD patients were that they were elderly in CD and were on higher doses of steroids. Routine histopathology studies and/or PCR for refractory colitis patients are suggested to diagnose CMV colitis. Once the diagnosis is made, antiviral treatment is recommended to decrease the colitis relapse rate.

    Mesalamine suppositories have been used widely for the treatment of distal ulcerative colitis and considered to be safer than systemic administration for its limited systemic absorption. However, previous studies have shown that mesalamine suppository occasionally causes severe hypersensitivity reactions including fever, rashes, colitis exacerbation and acute eosinophilic pneumonia. Here we present a 25-year-old woman with ulcerative colitis with bloody diarrhea accompanied by abdominal pain and fever which were aggravated after introduction of mesalamine suppositories. In light of symptom exacerbation of ulcerative colitis, increased inflammatory injury of colon mucosa shown by colonoscopy and elevated peripheral eosinophil count after mesalamine suppositories administration, and the Naranjo algorithm score of 10, the possibility of hypersensitivity reaction to mesalamine suppositories should be considered, warning us to be aware of this potential reaction after administration of mesalamine formulations even if it is the suppositories.

    Studies of women with ulcerative colitis (UC) during pregnancy have reported increased risks of preterm delivery, growth restriction, and congenital malformation. However, the results are inconsistent due to inadequate study design and limitations in sample size. We performed a population-based prevalence study on 2637 primiparous women with a UC hospital diagnosis prior to delivery and 868,942 primiparous women with no UC diagnosis in Denmark and Sweden, 1994-2006. Logistic regression analysis was used to estimate relative risks for moderately (32-36 weeks) and very (before 32 weeks) preterm birth, 5-minute Apgar score congenital abnormalities. Maternal UC was associated with increased risk of moderately preterm birth (prevalence odds ratio [POR] 1.77, 95% confidence interval [CI]: 1.54-2.05), very preterm birth (POR 1.41, 95% CI: 1.02-1.96), cesarean section (POR 2.01, 95% CI: 1.84-2.19), and neonatal death (POR 1.93, 95% CI: 1.04-3.60). The strongest associations were observed for prelabor cesarean section (POR = 2.78, 95% CI: 2.38-3.25) and induced preterm delivery (POR 2.55, 95% CI: 1.95-3.33). There was a slightly increased risk of SGA birth (POR 1.27, 95% CI: 1.05-1.54). We found no association between UC and overall risk of congenital abnormalities (POR 1.05, 95% CI: 0.84-1.31) or specific congenital abnormalities. Risks for adverse birth outcomes were higher in women with previous UC-related surgery and hospital admissions. Women with UC have increased risks of preterm delivery, SGA-birth, neonatal death, and cesarean section but not congenital abnormalities. Adverse birth outcomes appeared correlated with UC disease severity. Copyright © 2010 Crohn's & Colitis Foundation of America, Inc.

    Correlations between anal sphincter function as assessed by anorectal manometry and anal sphincter anatomy measured by endoluminal ultrasound have been reported in the literature both for patients and for healthy individuals but have not been confirmed by other authors. For a larger series of patients (152 consecutive patients, mean age 54.1 +/- 15.5 years; female:male ratio, 111:41) with anorectal dysfunctions such as incontinence (n = 92), constipation (n = 37), and other symptoms (n = 23), diagnostic work-up included conventional multilumen anorectal manometry to evaluate internal sphincter pressure at rest, maximum external sphincter squeeze pressure during contraction, and endoanal sonography to determine anal sphincter integrity and to measure dorsal, left lateral, and right lateral diameter of the internal anal sphincter (IAS) and external anal sphincter (EAS) muscles. Maximum squeeze pressure was significantly correlated to muscle thickness of the EAS (P = 0.001). No association was found between resting pressure and IAS diameter. Women had significantly lower resting and squeeze pressures than men (P = 0.008 and P = 0.003, respectively), but age-related changes of function were only found for resting pressure. Endosonographic values of IAS and EAS did not differ between genders but were significantly correlated with age (P = 0.008 and P = 0.02, respectively). Because all correlations were rather weak, they only can explain a small portion of data variance. Anal manometry and anal ultrasound, therefore, are of complementary value and are both indicated in adequate clinical problems.

    To evaluate the usefulness of endoanal ultrasonography and to determine the imaging features of patients with fecal incontinence, anal abscess or anal fistula. Twenty five patients underwent endoanal ultrasonography between October 1995 and July 1996. Ten of these were fecal incontinence cases, eight had an anal abscess, and seven, an anal fistula. The incontinence grading scale (IGS) was used for clinical grading of fecal incontinence and pudendal nerve terminal motor latency (PNTML) for pudendal nerve injury. Endoanal ultrasonographic features and operative findings were retrospectively reviewed. Endoanal ultrasonography revealed defective sphincteric muscles in all three patients with myogenic fecal incontinence, but in six of seven cases with neurogenic fecal incontinence, these muscles were not difective. Myogenic and neurogenic incontience showed different findings (p=3D0.033). In comparison with surgical findings, endoanal ultrasonography was 88% accurate in anal abscess cases and 86% accurate in those of anal fistula. Endoanal ultrasonography in conjunction with PNTML was very useful for the detection of the site and severity of sphincteric muscle defect and diagnosis of the etiology of fecal incontinence. Through analysis of the site and type of lesion, the procedure can also serve as a guide to the surgical treatment of patients with anal abscess or fistula.=20.

    Full Text Available In this review, we examined studies published on oral and topical formulations of budesonide (Entocort® and Budenofalk®, in Spain: Entocord® and Intestifalk® for the treatment of ulcerative colitis. This glycocorticosteroid has a potent local action and an important first-pass liver metabolism. It has proven successful over the last years as a controlled-release formulation. It obtained results similar to prednisolone, without the latter's significant suppression of plasma cortisol. Many publications exist on the effects of oral budesonide for the treatment of Crohn's disease (CD. These have led to the registration of this drug for the treatment of CD. Studies on oral formulations of budesonide for the treatment of ulcerative colitis (UC are scarce. After reviewing published evidence, we suggest the conduction of controlled trials for the treatment of UC to obtain evidence-based efficacy and safety results in order to benefit patients with this form of inflammatory bowel disease (IBD.En esta revisión repasamos los estudios publicados hasta la fecha con las formulaciones orales y las preparaciones tópicas rectales de budesonida (Entocort® y Budenofalk®, en España Entocord® e Intestifalk® para el tratamiento de la colitis ulcerosa.

The patient lost 50 pounds in the setting of a UC flare and was found to have an albumin level of 1.2 g/dl. Although the patient’s UC was clinically controlled with steroids, the weight loss and hypoalbuminemia persisted with the patient’s course complicated by development of deep vein thrombosis and pulmonary embolism. The diagnosis of PLE was confirmed with measurement of stool alpha-1-antitrypsin clearance. The patient’s condition significantly improved following procto-colectomy.

    Full Text Available Xanthogranulomatous inflammation (XGI is an uncommon pathological diagnosis involving various organ systems, the most common being the gall bladder and kidney. It can masquerade as a malignant mass thus, requiring a clinical suspicion for accurate and timely diagnosis. A 65-year-old woman presented with acute onset of obstipation and vomiting suggesting acute obstruction. Contrast enhanced computed tomography of abdomen revealed a solid irregular mass in the ascending colon with large necrotic areas and surrounding enlarged nodes suggestive of malignancy arising from right colon. Right hemi-colectomy was performed. Histopathology of the surgical specimen showed florid inflammatory infiltrate with collection of histiocytes, lymphocytes and polymorphs. Further immunohistochemistry was conducted, and CD68 and CD45 were found to be positive and pan-cytokeratin was negative. A clinico-pathological diagnosis was thus established to be xanthogranulomatous colitis.

They are characterized clinically by chronic nonbloody diarrhea and a macroscopically normal colonic mucosa where characteristic histopathological findings are seen. Previously considered rare, they now have emerged as common disorders that need to be considered in the investigation of the patient with chronic diarrhea. The annual incidence of each disorder is five to ten per 100,000 inhabitants, with a peak incidence in 60- to 70-year-old individuals and a predominance of female patients in collagenous colitis. The etiology and pathophysiology are not well understood, and the current view suggests an uncontrolled mucosal immune reaction to various luminal agents in predisposed individuals. Clinical symptoms comprise chronic diarrhea, abdominal pain, fatigue, weight loss, and fecal incontinence that may impair the patient's health-related quality of life. An association is reported with other autoimmune disorders, such as celiac disease, thyroid disorders, diabetes mellitus, and arthritis. The best-documented treatment, both short-term and long-term, is budesonide, which induces clinical remission in up to 80% of patients after 8 weeks' treatment. However, after successful budesonide therapy is ended, recurrence of clinical symptoms is common, and the best possible long-term management deserves further study. The long-term prognosis is good, and the risk of complications, including colonic cancer, is low. We present an update of the epidemiology, pathogenesis, diagnosis, and management of

    BACKGROUND: Debate persists regarding the role of Desulfovibrio subspecies in ulcerative colitis. Combined microscopic and molecular techniques enable this issue to be investigated by allowing precise enumeration of specific bacterial species within the colonic mucous gel. The aim of this study was to combine laser capture microdissection and quantitative polymerase chain reaction to determine Desulfovibrio copy number in crypt-associated mucous gel in health and in acute and chronic ulcerative colitis. METHODS: Colonic mucosal biopsies were harvested from healthy controls (n = 19) and patients with acute (n = 10) or chronic (n = 10) ulcerative colitis. Crypt-associated mucous gel was obtained by laser capture microdissection throughout the colon. Pan-bacterial 16S rRNA and Desulfovibrio copy number\\/mm were obtained by polymerase chain reaction at each locus. Bacterial copy numbers were interrogated for correlation with location and disease activity. Data were evaluated using a combination of ordinary linear methods and linear mixed-effects models to cater for multiple interactions. RESULTS: Desulfovibrio positivity was significantly increased in acute and chronic ulcerative colitis at multiple levels within the colon, and after normalization with total bacterial signal, the relative Desulfovibrio load was increased in acute colitis compared with controls. Desulfovibrio counts did not significantly correlate with age, disease duration, or disease activity but interlevel correlations were found in adjacent colonic segments in the healthy control and chronic ulcerative colitis groups. CONCLUSION: The presence of Desulfovibrio subspecies is increased in ulcerative colitis and the data presented suggest that these bacteria represent an increased percentage of the colonic microbiome in acute ulcerative colitis.

    Full Text Available Clostridium difficile colitis is a common infection that can be difficult to resolve and may result in recurrent infections. Reactive arthritis is a rare presentation of this disease and its treatment is not well differentiated in the literature. We describe a case of reactive arthritis occurring in a patient with a history of recurrent Clostridium difficile colitis while currently receiving a taper of oral vancomycin. His arthritis symptoms resolved with corticosteroids and continued treatment with anticlostridial antibiotics.

    Full Text Available Cytomegalovirus (CMV is a common pathogen worldwide. Clinically significant CMV infection is mostly seen in the context of immunosuppression, whether congenital, acquired, or iatrogenic. In the recent past, however, in both adults and children, an increasing number of moderate-to-severe cases of colitis have been described among immunocompetent patients. We describe a rare case of severe CMV colitis in an immunocompetent patient which resolved spontaneously.

    Background: Ulcerative colitis (UC) only involves the colonic mucosa. Yet, nearly 50% of patients with UC who undergo total proctocolectomy with ileal pouch anal anastomosis develop UC-like inflammation of the ileal pouch (pouchitis). By contrast, patients with familial adenomatous polyposis (FAP) with ileal pouch anal anastomosis develop pouchitis far less frequently. We hypothesized that pathogenic events associated with the development of UC are recapitulated by colonic-metaplastic transcriptomic reprogramming of the UC pouch. Methods: We prospectively sampled pouch and prepouch ileum mucosal biopsies in patients with UC with ileal pouch anal anastomosis 4, 8, and 12 months after their pouch was in continuity. Mucosal samples were also obtained from patients with FAP. Transcriptional profiles of the UC and FAP pouch and prepouch ileum were investigated via RNA sequencing and compared with data from a previously published microarray study. Results: Unlike patients with FAP, subjects with UC exhibited a large set of differentially expressed genes between the pouch and prepouch ileum as early as 4 months after pouch functionalization. Functional pathway analysis of differentially expressed genes in the UC pouch revealed an enhanced state of immune/inflammatory response and extracellular matrix remodeling. Moreover, >70% of differentially expressed genes mapped to published inflammatory bowel diseases microarray data sets displayed directional changes consistent with active UC but not with Crohn's disease. Conclusions: The UC pouch, well before histologic inflammation, already displays a systems-level gain of colon-associated genes and loss of ileum-associated genes. Patients with UC exhibit a unique transcriptomic response to ileal pouch creation that can be observed well before disease and may in part explain their susceptibility to the development of pouchitis.

    Treatment for anal fistulas in patients with Crohn's disease is still challenging, even for the expert surgeon. The advancement flap technique is characterized by the preservation of the anal sphincter complex. A systematic review of the literature, selecting series of patients affected by Crohn's disease and anal fistulas and treated using advancement flap technique was performed. Patients followed during at least 6 months have been included. From 128 initial studies, 11 studies were selected, including overall 135 patients. Those studies show low- level evidence. Results in a series with follow-up from 8,4 to 82 months, stated a clinical success of 66% and recurrence rate around 30%. However there was an evident heterogeneity of results. The review concludes that the advancement flap technique to treat anal fistulas in patients with Crohn's disease is an adequate alternative. New studies are necessary to provide higher-level evidence. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Inflammation of the colon is associated with increased production of prostaglandins (PG) and thromboxanes (Tx), and these eicosanoids may contribute to the inflammatory, secretory, and motility dysfunctions in colitis. To evaluate the potential role of peptide hormones in the enhanced eicosanoid release, colitis was established in rabbits by a delayed-type hypersensitivity reaction to dinitrochlorobenzene and by an immune-complex-mediated reaction. PG and Tx were identified in the venous effluent of isolated perfused colons by radiochromatography after ( UC)arachidonic acid prelabeling, as well as by bioassay, and then quantitated by immunoassay. The two colitis models were morphologically similar. Basal release of PGE2, PGI2, and TxA2 was two- to threefold greater from colitis tissue than from control tissue. Bradykinin (BK) and angiotensin II (ANG II) increased release of UC-labeled eicosanoids, whereas several gastrointestinal hormones had no effect. In control colons, BK and ANG II increased PGE2 and PGI2 release (by about 2-fold) but did not alter TxA2. In contrast, BK and ANG II markedly exaggerated the release of eicosanoids in colitis. Since BK and possibly ANG II are increased at sites of inflammation, the hypersensitive eicosanoid response to these peptides may augment the eicosanoid-mediated manifestations of colitis.

    To evaluate anal sphincter anatomy using three-dimensional ultrasonography (3-DAUS) in incontinent women with vaginal delivery, correlate anatomical findings with symptoms of fecal incontinence and determine the effect of vaginal delivery on anal canal anatomy and function. Female with fecal incontinence and vaginal delivery were assessed with Wexner's score, manometry, and 3DAUS. A control group comprising asymptomatic nulliparous was included. Anal pressure, the angle of the defect and length of the external anal sphincter (EAS), the anterior and posterior internal anal sphincter (IAS), the EAS + puborectal and the gap were measured and correlated with score. Of the 62, 49 had fecal incontinence and 13 were asymptomatic. Twenty five had EAS defects, 8 had combined EAS+IAS defects, 16 had intact sphincters and continence scores were similar. Subjects with sphincter defects had a shorter anterior EAS, IAS and longer gap than women without defects. Those with a vaginal delivery and intact sphincters had a shorter anterior EAS and longer gap than nulliparous. We found correlations between resting pressure and anterior EAS and IAS length in patients with defects. Fecal incontinence symptoms did not correlate with anal pressures and anal sphincter anatomy changes, but women with sphincter defects have shorter anterior EAS and IAS and a longer gap.

    Full Text Available  Introduction:Anal condylomata acuminata was a well-known disease in ancient times but in recent years there has been a rapidly increasing number of people who suffer from this disease. The main cause of this disease is infection of human papilloma virus (HPV which occurs through sexual contact.Currently there are three different ways to treat anal condylomata. Small changes of anal condylomata can be treated with local therapeutic agents, but the best results of treatment of extensive changes are obtained by surgical techniques.Material/Methods:The study group consisted of 30 patients with diagnosed extensive anal condylomata who underwent surgery in Mikolaj Pirogow High Specialized Hospital in Lodz. The survey was conducted from 2007 to 2011. Patients had been directed to the surgical ward by general surgeons and practitioners, proctologists and urologists. The diagnosis was made after proctological assessment in the knee-chest position.Results:All patients underwent surgery and had complete macroscopic electroexcision of anal condylomata. In the research group there was no mortality. Postoperative complications occurred in 4 (13.3�20patients – postoperative bleeding. Strong pain was present in 14 (46.7�20patients but only in the postoperative period. During postoperative follow-up there was no observed infection in the anal region or recurrence of disease. In the operated group there were no observed cosmetic deformations of the anus and/or the anal canal, narrow anal canal or functional fecal incontinence symptoms.Conclusions:Surgical treatment of anal condylomata is an effective and safe method for the patient. In our research there were no serious postoperative complications or recurrence of the disease during the follow-up period.

    Acute severe colitis is a potentially lethal medical emergency and, even today, its treatment remains a challenge for clinicians and surgeons. Intravenous corticoid therapy, which was introduced into the therapeutic arsenal in the 1950s, continues to be the first-line treatment and, for patients who are refractory to this, the rescue therapy may consist of clinical measures or emergency colectomy. To evaluate the indications for and results from drug rescue therapy (cyclosporine, infliximab and tacrolimus), and to suggest a practical guide for clinical approaches. The literature was reviewed using the Medline/PubMed, Cochrane library and SciELO databases, and additional information from institutional websites of interest, by cross-correlating the following keywords: acute severe colitis, fulminating colitis and treatment. Treatments for acute severe colitis have avoided colectomy in 60-70% of the cases, provided that they have been started early on, with multidisciplinary follow-up. Despite the adverse effects of intravenous cyclosporine, this drug has been indicated in cases of greater severity with an imminent risk of colectomy, because of its fast action, short half-life and absence of increased risk of surgical complications. Therapy using infliximab has been reserved for less severe cases and those in which immunosuppressants are being or have been used (AZA/6-MP). Indication of biological agents has recently been favored because of their ease of therapeutic use, their good short and medium-term results, the possibility of maintenance therapy and also their action as a "bridge" for immunosuppressant action (AZA/6-MP). Colectomy has been reserved for cases in which there is still no response five to seven days after rescue therapy and in cases of complications (toxic megacolon, profuse hemorrhage and perforation). Patients with a good response to rescue therapy who do not undergo emergency operations should be considered for maintenance therapy using

    Between 0.5 and 5% of vaginal deliveries involve obstetrical anal sphincter injuries (OASIS). Thirty to forty percent of patients with OASIS will suffer from anal incontinence in the subacute postpartum period. The aim of the present study was to assess the effectiveness of early pelvic floor muscle training (PFMT) combined with standard rehabilitation on anal incontinence after vaginal deliveries complicated by OASIS. The present work was a retrospective quantitative study performed in a tertiary-level maternity hospital. Women with 3rd or 4th degree obstetric tears were included. Women who gave birth between January 1st, 2011 and December 31st, 2012 underwent standard pelvic-perineal rehabilitation within 6-8 weeks postpartum. Women who gave birth between January 1st, 2013 and July 1st, 2014 had early rehabilitation (within 30 days after delivery) followed by the same standard rehabilitation received by the other group. Rehabilitation was performed by physiotherapists specialized in perineology. No electrostimulation was done in early rehabilitation. An in-house-validated modification of the Jorge and Wexner questionnaire was sent by mail to the patients to assess symptoms. The main judgment criterion was anal incontinence to gas, loose stools and/or solid stool. Two hundred and thirty patients were diagnosed with OASIS. Nineteen women (8.3%) were lost to follow-up. The intention-to-treat analysis included 211 patients, 109 of whom underwent standard rehabilitation and 102 early rehabilitation plus standard rehabilitation. The two groups were comparable in terms of parity, birth weight, assisted delivery, epidural anesthesia and rates of mediolateral episiotomy. Multivariate analyses adjusted for type of perineal lesion were performed. Early rehabilitation significantly reduced gas leakage: OR 0.51 [0.29-0.90] (p=0.02), liquid stool leakage: OR 0.22 [0.08-0.58] (p=0.02) and urinary stress incontinence: OR 0.43 [0.24-0.77] (p=0.004).

    The incidence of anal cancer has increased over the last 25 years. No organized screening exists for the precursors of anal cancer (anal intraepithelial neoplasia and carcinoma in situ) and diagnosis is often delayed. Treatment for precursor lesions is of limited success, while cancer management is traumatic for the patient. Like cancers of the cervix, most cases of anal cancer are associated with infection with human papillomavirus (HPV). With increases in the incidence of anal cancer, and in light of the availability of prevention strategies such as screening and HPV vaccination, it is important, from a public health perspective, to assess the economic burden of anal cancer in France. We performed a retrospective analysis based on data extracted from a French hospital database - the Programme de médicalisation des systèmes d'information (PMSI) - to assess the number and management of patients hospitalized for anal cancer in 2006. Data on radiotherapy sessions performed in private hospitals were obtained from the Statistiques annuelles des établissements de santé (SAE) database. Costs of hospitalization, from the healthcare-payer perspective, were obtained from official diagnosis-related group tariffs for public and private hospitals. Ambulatory and indirect costs were estimated using information obtained from the literature. In 2006, 3,711 patients with anal cancer were treated in hospitals in France. Of these, the majority were women (69%). The annual cost of hospital treatment for anal cancer was estimated at € 20,326,868. The overall estimated cost (including hospitalization, outpatient and daily allowances costs) to the healthcare payer was € 38,249,981. This study, the first to investigate the economic burden of anal cancer in France, shows that the management costs of anal cancer are high and comparable to cervical cancer management costs (€ 44 million). Further research is required to determine the cost of management of precursor lesions, which

    Shoulder dystocia is an obstetric emergency that occurs in 0.2-3% of all cephalic vaginal deliveries. We hypothesized that because of the difficult nature of deliveries complicated by shoulder dystocia, the condition may be associated with anal sphincter injury. We sought to identify risk factors for obstetric anal sphincter injury in women with shoulder dystocia. This retrospective analysis included all cases of shoulder dystocia from 2007 to 2011 at two large tertiary referral centers, in the USA and Ireland. Details of maternal demographics, intrapartum characteristics, and delivery outcomes in cases of shoulder dystocia were analyzed. Univariate and multivariate analyses were used to describe the association between shoulder dystocia and anal sphincter injury. There were 685 cases of shoulder dystocia, and the rate of shoulder dystocia was similar at both institutions. The incidence of anal sphincter injury was 8.8% (60 out of 685). The rate was 14% (45 out of 324) in nulliparas and 4.2% (15 out of 361) in multiparas. Women with sphincter injury were more likely to be nulliparous (75% [45 out of 60] vs 45% [279 out of 625]; p shoulder dystocia, the risk of anal sphincter injury is 9%. Risk factors include nulliparity, operative vaginal delivery, and use of internal maneuvers, whereas episiotomy was found to have a protective effect against anal sphincter injury during cases of shoulder dystocia.

    To evaluate the diagnostic significance of appendiceal orifice inflammation (AOI) in ulcerative colitis (UC) patients. We retrospectively examined data from patients with colitis from May 2010 to January 2014 and assigned them to two groups: UC cases and specific colitis cases. First, we clarified the difference in the AOI+ rate between the two groups. Thereafter, imaging findings of all the patients with colitis were re-examined. Features of AOI alone or in combination with proctitis (referred to as "combination features") were considered as the two separate diagnostic criteria for diagnosing UC. By comparing the current diagnoses with the previous diagnoses, evaluation indexes were obtained. A total of 3582 colitis cases (UC cases: 427; specific colitis cases: 3155) were examined. The mean AOI+ rates in UC and specific colitis cases were 26.2% and 0.7%, respectively; a Chi-squared test indicated that the difference between these rates was statistically significant (x2=6.81; pUC, the sensitivity was 26.2% [95% confidence interval (CI), 22.3%-30.6%], agreement rate was 90.6%, and specificity was 99.3% (95% CI, 98.9%-99.5%). When the combination features were used to diagnose UC, the sensitivity was 26.2% (95% CI, 22.3%-30.6%), agreement rate was 91.1%, and specificity was 99.9% (95% CI, 99.7%-100%). Combining AOI features and proctitis may lead to a more effective UC diagnosis and enable physicians to identify this condition more promptly among miscellaneous diseases.

    Full Text Available PURPOSE: To quantify the intensity of sulfomucin and sialomucin expression in the colon mucosa, by means of computer-assisted image processing, comparing segments with and without fecal stream and correlating with the duration of fecal transit exclusion. METHODS: Forty-five Wistar rats were subjected to diversion of the fecal stream in the left colon by means of constructing a proximal colostomy and distal mucosal fistula. They were distributed randomly into three experimental groups of 15 animals, of which 10 were subjected to colon diversion (experimental subgroup and five were only subjected to laparotomy, without colon diversion (control subgroup. The three experimental groups were formed according to the sacrifice date, which was to be performed six weeks after the surgical procedure (Group A, 12 weeks (Group B and 18 weeks (Group C. The sulfomucin and sialomucin expression in the colon mucosa was evaluated using the histochemical technique of high iron diamine-alcian blue (HID-AB. The tissue expression was quantified for each animal, in the segments with and without fecal stream, at a location where there were four complete contiguous crypts in two random fields, with the aid of the computer-assisted image analysis software. The final value was taken to be the mean reading from the two fields selected, in the segments with and without fecal stream. To compare the expressions of the two mucin subtypes in the segments with and without fecal stream, the paired Student t test was used. To analyze variance according to duration of exclusion, ANOVA with the Newman-Keuls post-test was used, setting the significance level at 5% (pOBJETIVO: Quantificar, por meio de processamento de imagem assistida por computador, a intensidade de expressão de sulfomucinas e sialomucinas na mucosa cólica comparando segmentos com e sem trânsito e relacionando-a ao tempo de exclusão de trânsito fecal.

    The incidence of high-grade anal intraepithelial neoplasia (HGAIN) -with an aetiological based on high-risk types of human papillomavirus- is increasing in some high-risk groups. Screening for HGAIN includes routine anal cytology and, more recently, HPV genotyping. The main objective of this study was to determine the sensitivity and specificity of anal cytology and HPV genotyping for the detection of HGAIN. This is a study to determine the correlation of cytological and microbiological findings with anal biopsy findings in a cohort of patients at high risk of developing AIN referred to the department of sexually transmitted infections of the Hospital Costa del Sol, Spain, between January 2008 and December 2014. Of the 151 patients subjected to screening, a total of 92 patients, all of them with the result of three screening test (anal cytology, genotyping and biopsy) were included in the study. Just under two-thirds (62%) of them were HIV-positive. The sensitivity and specificity of anal cytology to detect HGAIN were 52.8 and 85.7%, respectively (k: 0.328), and 78 and 62.8% to detect two or more HPV oncogenic genotypes (k: 0.417). The detection of oncogenic HPV genotypes allowed the identification of 23 new cases of HGAIN that had been underdiagnosed with anal cytology, with 14 cases containing at least three high-risk genotypes. Anal cytology did not show enough sensitivity in HGAIN screening. HPV genotyping has shown to be a useful tool to detect HGAIN cases, although it could lead to an over-diagnosis as a solitary screening procedure.

    Full Text Available OBJECTIVE: The prevention of anal cancer is a goal of worldwide Aids support centers. Despite the efforts that have been made and progress in the antiretroviral therapy, effective disease control remains elusive. Difficulty in preventing anal cancer may result from the ineffectiveness of highly active antiretroviral therapy on the human papillomavirus (HPV since the coinfection with HIV and HPV appears to increase the risk of HPV-infected cells, becoming cancerous. METHODS: We evaluated 69 HIV-positive and 30 HIV-negative male patients who underwent cytological evaluation by RT-PCR for the presence of HPV, Epstein-Barr virus, cytomegalovirus and herpes virus types (HSV 1 and 2, and histopathology analysis of the anal canal. RESULTS: The prevalence of anal intraepithelial neoplasia was 35% and it was restricted to HIV-positive patients. Patients infected with high-risk HPV and with fewer than 50 TCD4 cells/µL showed an anal intraepithelial neoplasia rate of 85.7% compared to those with TCD4 cells >200 cells/µL (pOBJETIVO: A prevenção do câncer anal tem sido aplicada pelos centros de apoio a pacientes com Aids em todo o mundo. Apesar dos esforços empregados, o eficaz controle da doença permanece distante.

    PURPOSE: Although functional results after ileal pouch-anal anastomosis are excellent, imperfections of function do occur. In this setting, quality-of-life assessment is an invaluable tool in determining overall therapeutic efficacy. We evaluated the impact of dietary restrictions, preoperative diagnosis (ulcerative colitis vs. familial adenomatous polyposis), and pregnancy (after pouch insertion) on quality of life. METHODS: After ethical approval, 64 patients were reviewed (mean age, 31 (range, 15-54) years). Long-term quality of life in patients after ileal pouch-anal anastomosis was assessed using the Cleveland Global Quality of Life instrument or Fazio score. The Cleveland Global Quality of Life score is a novel quality-of-life instrument specifically designed for patients with ileal pouches. Stool frequency and continence were recorded to establish the functional status of this group. RESULTS: Sixty-one patients (95.3 percent) complained of some form of dietary restriction and adopted a fixed dietary regimen. All such patients felt that a breach of this regimen would impinge significantly on their quality of life. Late eating and alcohol were associated with diarrhea, whereas smoking was not. Constipation was infrequently reported. The mean Cleveland Global Quality of Life score of patients with ulcerative colitis (0.81 +\\/- 0.13) was greater than that of patients with ulcerative colitis and a background of pouchitis (0.78 +\\/- 0.16; P = 0.042). Whereas postoperative stool frequency in patients with familial adenomatous polyposis was always higher than the preoperative level (4 vs. 2 movements per day; P = 0.04), the Cleveland Global Quality of Life score of this group was lower than that of ulcerative colitis patients (0.77 vs. 0.81; P = 0.047). The Cleveland Global Quality of Life score of females who had had pregnancies after pouch formation was 0.70, significantly lower (P = 0.039) than that of ulcerative colitis patients, although pouch function was

    Full Text Available Background: Golimumab is a TNF-blocking agent indicated as a second-line therapy in ulcerative colitis. Purpose: To research the effectiveness and safety of golimumab in patients with ulcerative colitis in clinical practice. Methods: Retrospective study of the effectiveness and safety of golimumab in patients with ulcerative colitis. All patients received golimumab 200 mg subcutaneously at week 0, and golimumab 100 mg subcutaneously at week 2. After the induction treatment, each patient received 50 mg sc. every 4 weeks in patients with body weight less than 80 kg, and 100 mg every 4 weeks in patients with body weight greater than or equal to 80 kg. Results: Study of a group of 23 ulcerative colitis patients, 7 of whom were naive to any anti-TNF therapy, and 16 patients who had previously been treated with an anti-TNF agent other than golimumab (non-naive patients. The average treatment time with golimumab was 14.3 weeks. Globally, withdrawal of corticosteroids was observed in 74% of cases. Clinical response was observed in 85.5% of patients who had not received biological treatment previously, and in patients who had previously received biological treatment the response rate was 75%. Conclusions: In this short study, golimumab seems to be an alternative treatment in naive and non-naive anti-TNF ulcerative colitis patients. It is also a safe therapy, given that there were no adverse effects in the patients studied.

  6. Fulminant Amebic Colitis after Corticosteroid Therapy: A Systematic Review.

    Full Text Available Amebic colitis, caused by intestinal infection with the parasite, Entamoeba histolytica, is a common cause of diarrhea worldwide. Fulminant amebic colitis is the most devastating complication of this infection, associated with both high mortality and morbidity. We conducted a review of the English literature to describe cases of fulminant amebic colitis associated with exposure to corticosteroid medications in order to identify the risk factors for poor outcome and determine difficulties in diagnosis and treatment.Articles reporting severe and fulminant forms of amebic colitis between 1991 and 2016 were collected. 525 records were screened to identify 24 cases for qualitative analysis associated with corticosteroid use. Cases arose from areas of high endemicity or travel to such areas. Most cases (14 of 24, 58% were given corticosteroids for initially misdiagnosed colitis, mainly inflammatory bowel, resulting in rapid progression of disease. Nearly half of all cases underwent surgical intervention, and 25% of cases died, despite all patients eventually receiving treatment with metronidazole. The odds of death did not differ significantly by prior misdiagnosis, co-morbidities, bowel perforation or need for surgery.Infection with E. histolytica should be considered prior to the administration of corticosteroids, in particular for patients residing in endemic areas or those with appropriate travel history, especially prior to the diagnosis of inflammatory bowel disease. The development of preventative and treatment interventions are needed to improve outcomes of fulminant disease.

    We analysed the CT examinations of 109 patients with 197 involved bowel locations. 81 patients suffered from Crohn's disease, 28 from ulcerative colitis. Diagnosis was based on the combination of clinical, endoscopic and histopathologic findings. Three radiologists evaluated the CT series concerning the presence of morphologic changes analogous to conventional radiographic findings. In Crohn's disease, we found irregular outer contours in 26% of cases. The bowel wall was thickened in 82%. In acute phases, the bowel wall was thickened in 100%. Abscess and fistula as complications of inflammatory disease were present in 26 and 14% respectively. In ulcerative colitis, a target sign of the bowel wall was present in 40%, whereas in Crohn's disease a homogeneous wall density was present in all but two cases. Reduced attenuation due to submucosal fat deposits was found in 16% and mucosal tunneling in 27% of cases with ulcerative colitis. Even if severe mucosal destructions were found, the outer contour of the gut was smooth and regular in 95% of the ulcerative colitis cases. CT can provide additional information on acuity, extent and complications in inflammatory bowel disease. In combination with conventional radiographic findings a three-step classification for Crohn's disease and ulcerative colitis (early changes, acute and chronic phase) can be proposed. (orig./MG) [de

    A spectrum of nodular haustral thickening and an 'accordion' pattern have been reported as specific features of pseudomembranous colitis (PMC) in adults. A retrospective review of nine patients with PMC was performed to assess whether this spectrum of CT findings also occurred in children. In four girls and five boys, CT scans were performed within 3 days of a positive stool toxin assay for Clostridium difficile. Documented CT abnormalities included nodular haustral thickening, the 'accordion' pattern, colonic wall thickening, ascites, and pericolonic edema. These results were then correlated as to their impact on the clinical outcome. Circumferential colon wall thickening was identified in 7/9 (78%) patients (mean thickening 14.5 mm). Nodular haustral thickening was identified in 4/9 (44%) and the 'accordion' pattern in 2/9 (22%). Other findings included pericolonic edema in 3/9 (33%) and ascites in 1/9 (11%). Wall thickening was confined to the left colon and rectum in 2/9 (22%), to the right colon in 2/9 (22%), and involved the whole colon in 3/9 (33%). Although CT findings associated with PMC in children may be suggestive for this diagnosis, CT is less specific than laboratory and clinical findings. (orig.)

    2014-01-01

    The association between ulcerative colitis (UC) and colorectal cancer (CRC) has been acknowledged. One of the most serious and life threatening consequences of UC is the development of CRC (UC-CRC). UC-CRC patients are younger, more frequently have multiple cancerous lesions, and histologically show mucinous or signet ring cell carcinomas. The risk of CRC begins to increase 8 or 10 years after the diagnosis of UC. Risk factors for CRC with UC patients include young age at diagnosis, longer duration, greater anatomical extent of colonic involvement, the degree of inflammation, family history of CRC, and presence of primary sclerosing cholangitis. CRC on the ground of UC develop from non-dysplastic mucosa to indefinite dysplasia, low-grade dysplasia, high-grade dysplasia and finally to invasive adenocarcinoma. Colonoscopy surveillance programs are recommended to reduce the risk of CRC and mortality in UC. Genetic alterations might play a role in the development of UC-CRC. 5-aminosalicylates might represent a favorable therapeutic option for chemoprevention of CRC. PMID:25469007

    Ulcerative colitis (UC) is a chronic inflammation of the large bowel characterized by diarrhea and a negative stool culture. However, several enteropathogens have been implicated as causative agents in UC. The differentiation between chronic infectious colitis (IC) and UC with concurrent infection is difficult owing to their similar clinical presentations. The study aimed to explore the presentations and diagnostic clues that enable differentiation between UC with concomitant infections and chronic IC. The study included 17 UC patients with a bacterial infection and 46 with chronic IC. The UC patients (47 ± 19 years) were younger than the chronic IC patients (58 ± 20 years) (P = 0.022). Bloody diarrhea was more common in UC than in chronic IC (58.8% vs 10.9%, P UC patients had lower antibiotic response rates than chronic IC patients (60.0% vs 87.2%, P = 0.026). Aeromonas species and Clostridium difficile were common in both groups. Histological features of cryptitis and crypt abscess were useful in the diagnosis of UC (P = 0.052 and P = 0.016, respectively). Bloody diarrhea in a young adult, decreased response to antibiotic treatment, and results of endoscopy with biopsy are important features in the diagnosis of UC with bacterial infection.

    AIM: To identify characteristic endoscopic findings and risk factors for cytomegalovirus (CMV)-associated colitis in patients with active ulcerative colitis (UC). METHODS: A total of 149 UC patients admitted to the Department of Gastroenterology, Nagoya University Hospital, from January 2004 to December 2013 with exacerbation of UC symptoms were enrolled in this retrospective study. All medical records, including colonoscopy results, were reviewed. CMV infection was determined by the presence of CMV antigen, CMV inclusion bodies in biopsy specimens, or positive specific immunohistochemical staining for CMV. Multivariate analysis was used to identify independent risk factors for CMV colitis. RESULTS: Multivariate analysis indicated independent associations with the extent of disease (pancolitis) and use of > 400 mg corticosteroids for the previous 4 wk. In contrast, no association was seen with sex, age at UC diagnosis, immunomodulator use, or infliximab use. Punched-out ulceration was also significantly associated with CMV infection in patients with active UC (odds ratio = 12.672, 95%CI: 4.210-38.143). CONCLUSION: Identification of a total corticosteroid dose > 400 mg for 4 wk, extensive colitis and a specific endoscopic finding of punched-out ulcer might facilitate the more rapid diagnosis and timely initiation of antiviral therapy for CMV-associated colitis in patients with active UC.

    To assess long-term outcomes after ileal pouch-anal anastomosis (IPAA) in Crohn's disease (CD). Although considered the procedure of choice in ulcerative colitis, performance of ileal pouch-anal anastomosis (IPAA) is controversial in CD. CD patients were identified from a prospectively maintained IPAA database. Time-to-diagnosis and pouch retention rates were analyzed using Kaplan-Meier curves. Demographic, clinical, and pathologic factors associated with pouch retention were evaluated with log-rank test and Cox proportional hazards model. Two hundred and four CD patients (108 female, median age 33 years, and median follow-up 7.4 years) with primary IPAA were included. CD diagnosis was before IPAA (intentional) in 20(10%), from postoperative histopathology (incidental) in 97(47%) or made in a delayed fashion at median 36 months after IPAA in 87(43%). Overall 10-year pouch retention was 71%. On multivariate analysis, pouch loss was associated with delayed diagnosis (P = 0.03, hazard ratio [HR] 2.6 (95% confidence interval [CI] 1.1-6.5)), pouch-vaginal fistula (P = 0.01, HR 2.8 (95% CI 1.3-6.4)), and pelvic sepsis (P = 0.0001, HR 9.7(95% CI 3.4-27.3)). Patients with retained IPAA at follow-up had near-perfect/perfect continence (72%), rare/no urgency (68%) with median daily bowel movements 7 (range 2-20). Median overall quality of life, quality of health, level of energy, and happiness with surgery were 9, 9, 8, and 10 of 10, respectively. For CD patients with IPAA, when the diagnosis is established preoperatively or immediately following surgery, pouch loss rates are low and functional results are favorable. Outcomes in patients with delayed diagnosis are worse but half retain their pouch at 10 years with good functional outcomes.

We investigated the risk of UC extension and subsequent risk of surgery in a Danish population-based cohort. Methods......: All incident UC cases in a strictly defined Copenhagen area between 2003 and 2004 were followed prospectively through 2011. Disease extension was defined as patients with limited UC [E1 or E2] at diagnosis having progressed from the initial extent by colonoscopy or surgery to E2 or extensive colitis...... experienced disease extension. Only extent at diagnosis was a clinical predictor for disease extension. The risk of colectomy was increased in former smokers and patients who progressed to extensive colitis.

    Full Text Available A 61-year-old Punjabi female patient presented with six months history of mild abdominal discomfort with bloody diarrhea. She did not have underlying chronic medical illness; she neither took steroid nor immunosuppressant. She was found anemic, thrombocytosis, and elevated C-reactive protein. Colonoscopy showed moderate left sided colitis, with histopathology evidence of ulcerative colitis (UC with cytomegalovirus (CMV infection. Her serum anti-CMV IgM antibody was detected. She was treated with intravenous ganciclovir, together with 5-ASA and tapering dose of steroid. Anemia was corrected. Subsequent clinic reviews and follow up endoscopies showed dramatically improvement. CMV colitis should be considered for the patients presenting with moderate to severe UC. Early prescription of antiviral would be beneficial in the treatment of flare of UC.

    Full Text Available INTRODUCTION: Imiquimod is a topical chemotherapic and immunostimulant agent with antitumoral and antiviral activities, used for anal condylomata acuminata treatment, mainly in recurrences. OBJECTIVE: Evaluate the imiquimod efficiency in chronic and recurrent anal condylomata acuminata in HIV-infected persons. METHOD: A prospective study that analyzed 61 patients with recurrent anal condylomata treated with topic 5% imiquimod, for at least 8 weeks. These patients had already been submitted to other topical and surgical treatments for anal warts. We evaluated the efficiency of this agent, through wart remission, with clinical examination and high-resolution anoscopy, CD4+ T lymphocyte count and side effects. The patients were 55 males and 6 females, from 22 to 63 years old. RESULTS: Remission was seen in 90%, being 46% complete remission and 44% partial remission. Other 10% did not respond to the treatment with imiquimod within the 16th week. Recurrences were observed in 11% of patients in 24-week follow-up. Statistics showed no differences in CD4+ T cell scores when groups with and without complete remission were compared. Adverse effects were reported by 45% of patients. They were mild to moderate burning (25%, intense burning (7%, ulcerative dermatitis (8% and systemic symptoms (5%. CONCLUSION: Imiquimod was effective in controlling recurrent anal condylomata acuminata in HIV-positive patients, regardless of CD4+ T cell count.INTRODUÇÃO: O imiquimode é agente tópico quimioterápico e imunoestimulante, com atividades antitumoral e antiviral, usado para tratamento dos condilomas acuminados perianais, principalmente os recidivantes.

    Obstetric anal sphincter injury (OASI) is the most common cause of anal incontinence and ano-rectal symptoms in women 1 . Reported rates of anal incontinence following primary repair of OASI range between 15-61%, with a mean of 39% 2, 3 . Other possible complications of OASI include perineal pain, dyspareunia, and less commonly, abscess formation, wound breakdown, and rectovaginal fistulae. Symptom onset may occur immediately, several years postpartum, or only late in life when aging of tissues adds to the delivery insult. Having sustained an OASI may impact significantly on women's physical and emotional health. Missed OASI, inadequate repair or lack of follow up are potential sources of litigation 4 . The reported incidence of OASI may be as high as 4-6.6% 4 , averaging 2.9% in the UK 3 . The incidence is higher in primiparae (6.1%) than in multiparae (1.7%) 3 . Recent years are seeing an increased awareness and structured training programs, which appear to have resulted in an increase in the detection rate of OASI 3 . The following risk factors have been identified with varying risk rates reported 3 : Asian ethnicity (OR 2.27, 95% CI 2.14-2.41), nulliparity (relative risk [RR] 6.97, 95% CI 5.40-8.99), birth weight greater than 4 kg (OR 2.27, 95% CI 2.18-2.36), shoulder dystocia (OR 1.90, 95% CI 1.72-2.08), occipito-posterior position (RR 2.44, 95% CI 2.07-2.89), prolonged second stage of labor (up to RR 2.02, 95% CI 1.62-2.51 after four hours duration). Instrumental deliveries and episiotomy use have been extensively studied resulting in the following evidence: Vacuum delivery without episiotomy (OR 1.89, 95% CI 1.74-2.05); vacuum delivery with episiotomy is protective (OR 0.57, 95% CI 0.51-0.63); forceps delivery without episiotomy carries the highest potential risk (OR 6.53, 95% CI 5.57-7.64); and forceps delivery with episiotomy (OR 1.34, 95% CI 1.21-1.49). Other potential risk factors have been suggested with varying evidence such as advanced maternal age at

    Diverse T help (Th) cells play a crucial role in the processing and maintaining of chronic inflammation as seen in ulcerative colitis (UC). Th9, a novel subset of Th cells that primarily produces interleukin (IL)-9, has recently been associated with the development of inflammatory diseases. In this study, we evaluated the presentation of Th9 cells in inflamed tissues of human and experimental mouse UC, and examined the therapeutic efficiency of anti Th9 cytokine IL-9 in the experimental mouse UC. Using immunohistochemistry (IHC), we evaluated the presentation of Th9 cells labelled by transcriptional factor PU.1 in both human and dextran sulfate sodium (DSS) induced mouse colitis biopsies. The results showed that increased PU.1 positive Th9 cells were mainly located in the lamina propria in relative with the controls, intraepithelial Th9 cells can also be observed but at low density. Double IHCs revealed that most of PU.1 positive cells were CD3 positive lymphocytes in human UC specimens. Anti-IL-9 antibody injection for 2 weeks reduced the severity of inflammation in DSS induced colitis mice. Our results suggest that The Th9/IL-9 is involved in the pathogenesis of UC. - Highlights: • The density of novel PU.1 positive Th9 cells is significantly increased in both human and mouse colitis tissues. • PU.1 positive Th9 cells are predominately located in the inflamed lamina propria in both human and mouse colitis tissues. • Blocking of Th9 cytokine IL-9 by antibody injection suppresses the severity of inflammation in the bowel in colitis mice. • Novel Th9 cells contribute to the pathogenesis of UC.

    Colorectal cancer (CRC) remains a feared and potentially life-threatening complication of both ulcerative colitis and Crohn\\'s colitis. Currently, the main preventive strategy is a secondary one, i.e. surveillance colonoscopy usually after 8 years of disease duration, when the risk for neoplasia begins to increase. Despite its widespread acceptance, dysplasia and cancer surveillance is unproven in terms of reducing mortality or morbidity and there is a remarkable lack of uniformity in the manner in which it is practised. In this review article, the pitfalls of dysplasia surveillance are summarized and the need for novel chemopreventive and perhaps pharmabiotic approaches for prevention are highlighted.

    To investigate the preventive effect of kefir on colitis induced with dextran sulfate sodium (DSS) in rats. Twenty-four male Wistar-albino rats were randomized into four groups: normal control, kefir-control, colitis, and kefir-colitis groups. Rats in the normal and kefir-control groups were administered tap water as drinking water for 14 d. Rats in the colitis and kefir-colitis groups were administered a 3% DSS solution as drinking water for 8-14 d to induce colitis. Rats in the kefir-control and kefir-colitis groups were administered 5 mL kefir once a day for 14 d while rats in the normal control and colitis group were administered an identical volume of the placebo (skim milk) using an orogastric feeding tube. Clinical colitis was evaluated with reference to the disease activity index (DAI), based on daily weight loss, stool consistency, and presence of bleeding in feces. Rats were sacrificed on the 15(th) day, blood specimens were collected, and colon tissues were rapidly removed. Levels of myeloperoxidase (MPO), tumor necrosis factor (TNF)-α, interleukin (IL)-10, malondialdehyde, and inducible nitric oxide synthase (iNOS) were measured in colon tissue. The DAI was lower in the kefir-colitis group than in the colitis group (on the 3(rd) and 5(th) days of colitis induction; P kefir-control groups. The DAI was statistically higher only on the 6(th) day in the kefir-colitis group when compared to that in the normal control groups. Increased colon weight and decreased colon length were observed in colitis-induced rats. Mean colon length in the colitis group was significantly shorter than that of the kefir-control group. Kefir treatment significantly decreased histologic colitis scores (P kefir-control group (P Kefir treatment significantly reduced the DSS colitis-induced TNF-α increase (P kefir-colitis groups (P Kefir reduces the clinical DAI and histologic colitis scores in a DSS-induced colitis model, possibly via reduction of MPO, TNF-α, and iNOS levels.

    Full Text Available Three cases of coexisting ulcerative colitis and Crohn’s disease are presented. In the first case, the patient had a long-standing history of ulcerative proctitis before developing Crohn’s colitis. In the two remaining cases, the patients presented initially with Crohn’s disease of the ileum and, subsequent to resection, developed ulcerative colitis. Well-documented cases of patients diagnosed with both ulcerative colitis and Crohn’s disease are rare. The literature on such cases is reviewed, and the controversy over whether ulcerative colitis and Crohn’s disease are two distinct diseases is explored.

    Full Text Available Existe la necesidad de una estrategia metodológica eficaz para sostener la investigación sobre la práctica profesional de los servicios sociales. La oposición entre el trabajo autoetnográfico de Carolyn ELLIS y Arthur BOCHNER (2000, 2006 y la propuesta analítica de Leon ANDERSON sirven como una lente a través de la cual explorar los aspectos clave de esta discusión. Mientras ELLIS y BOCHNER rechazan cualquier intento de abstracción o sistematización teórica, ANDERSON pretende tender puentes entre la tradición etnográfica y las formas emergentes de narrativa personal.

    Patients with microscopic colitis (MC) have several risk factors for osteoporosis. The prevalence of osteopenia and osteoporosis in MC is unknown. The primary purpose of this study was to evaluate bone mineral status in MC. Patients with MC and disease activity within the last 2 years were included. Bone turnover markers were analyzed and bone mineral density (BMD) was measured with Dual Energy X-ray Absorptiometry (DXA) at inclusion and after one year. Medical history, demographics, risk factors for osteoporosis, disease activity and treatment with cumulative budesonide dosage at least 3 years before inclusion was registered. Adrenal function was tested by adrenocortico-tropic hormone (ACTH) and an ACTH stimulation test at inclusion. Results were compared with age and sex-matched controls. Fifty MC patients (44 women) were included. Median age 67 (range 45-93); median disease duration 28 month (range 2-163); median cumulative budesonide dosage 702 mg (range 0-5400). No difference in number of patients with osteoporosis or osteopenia and BMD was detected between groups. The bone mineral formation marker specific alkaline phosphatase was lower in MC than controls 12 (5-69) µg/l versus 16 (10-35) µg/l (p <   0.005). Patients more often smoked (34% versus 10%, p = 0.001). Disease duration and cumulative budesonide dose was associated with lower BMD and T-score in hip (Spearman's rho; p < 0.05) with a cut of point of 2500 mg budesonide predicting osteopenia. Budesonide treatment did not affect adrenal gland function. The risk of osteoporosis in patients with MC is not increased. However, DXA scan is recommended in MC patients with known risk factors or active disease requiring longstanding budesonide treatment. Supplementation of calcium and vitamin-D in patients treated with budesonide is recommended.

He presented with a two-month history of mild anal symptoms, including pruritus and episodic bleeding. He referred past episodes of anal warts, self-treated with several topical compounds, all proven unsuccessful. Perianal examination showed erythema and scratching. A 0.5cm sized tumor, with infiltration at the base was detected on digital exam, located at 15mm from the anal margin. Local biopsy driven by high-resolution anuscopy (AAR) yielded a final diagnosis of infiltrative epidermoid carcinoma. Might that neoplasia have been prevented? Copyright © 2013 Elsevier España, S.L.

    Morphological and functional changes in the enteric nervous system (ENS) have been reported in inflammatory bowel disease. We examined the effects of inflammation on the expression of choline acetyltransferase (ChAT) and nNOS in the muscularis externae of two models of colonic inflammation, trinitrobenzene sulfonic acid (TNBS)-induced colitis, which models Crohn's disease-like inflammation, and DSS-induced colitis, which models ulcerative Colitis-like inflammation. In TNBS colitis, we observed significant decline in ChAT, nNOS, and protein gene product (PGP) 9.5 protein and mRNA levels. In DSS colitis, ChAT and PGP9.5 were significantly upregulated while nNOS levels did not change. The nNOS dimer-to-monomer ratio decreased significantly in DSS- but not in TNBS-induced colitis. No differences were observed in the percentage of either ChAT (31 vs. 33%)- or nNOS (37 vs. 41%)-immunopositive neurons per ganglia or the mean number of neurons per ganglia (55 ± 5 vs. 59 ± 5, P > 0.05). Incubation of the distal colon muscularis externae in vitro with different types of inflammatory mediators showed that cytokines decreased ChAT and nNOS expression, whereas H₂O₂, a component of oxidative stress, increased their expression. NF-κB inhibitor MG-132 did not prevent the IL-1β-induced decline in either ChAT or nNOS expression. These findings showed that TNBS- and DSS-induced inflammation differentially regulates the expression of two critical proteins expressed in the colonic myenteric neurons. These differences are likely due to the exposure of the myenteric plexus neurons to different combinations of Th1-type inflammatory mediators and H₂O₂ in each model.

    Sphincter-preserving procedures for the treatment of transsphincteric fistulas fail in at least one out of every three patients. It has been suggested that failure is due to ongoing disease in the remaining fistula tract. Cytokines play an important role in inflammation. At present, biologicals targeting cytokines are available. Therefore, detection and identification of cytokines in anal fistulas might have implications for future treatment modalities. The objective of the present study was to assess local production of a selected panel of cytokines in anal fistulas, including pro-inflammatory interleukin (IL)-1β and tumor necrosis factor α (TNF-α). Fistula tract tissue was obtained from 27 patients with a transsphincteric fistula of cryptoglandular origin who underwent flap repair, ligation of the intersphincteric fistula tract or a combination of both procedures. Patients with a rectovaginal fistula or a fistula due to Crohn's disease were excluded. Frozen tissue samples were sectioned and stained using advanced immuno-enzyme staining methods for detection of selected cytokines, IL-1β, IL-8, IL-10, IL-12p40, IL-17A, IL-18, IL-36 and TNF-α. The presence and frequencies of cytokine-producing cells in samples were quantitated. The key finding was abundant expression of IL-1β in 93 % of the anal fistulas. Frequencies of IL-1β-producing cells were highest (>50 positive stained cells) in 7 % of the anal fistulas. Also, cytokines IL-8, IL-12p40 and TNF-α were present in respectively 70, 33 and 30 % of the anal fistulas. IL-1β is expressed in the large majority of cryptoglandular anal fistulas, as well as several other pro-inflammatory cytokines.

    Full Text Available Abstract Introduction Myotonic dystrophy (MD or Steinert's syndrome is a rare cause of chronic diarrhea and anal incontinence. In the presence of chronic diarrhea and fecal incontinence with muscle weakness, neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis. Case Presentation We present the case of a 45-year-old Turkish man with Steinert's syndrome, who was not diagnosed until the age of 45. Conclusions In clinical practice, the persistence of diarrhea and fecal incontinence with muscle weakness should suggest that the physician perform an anal manometric study and electromyography. Neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis.

    Studies on surgical procedures in patients with concomitant primary sclerosing cholangitis (PSC) and ulcerative colitis (UC) have mainly been restricted to single centers. The aim was to compare surgical treatment of UC with or without PSC in a nationwide study. A cohort study including all patients diagnosed with UC between 1987 and 2014 in Sweden was undertaken. The impact of PSC on the risk of colectomy, the chance of restorative surgery, and risk of failure (presence of a stoma) following restorative surgery were estimated. Survival analyses were performed using the Kaplan-Meier method and multivariable Cox regression models. Of 49 882 UC patients, 2079 had a PSC diagnosis at the end of follow-up. The risk of colectomy was unaffected by PSC diagnosis, whereas the chance of restorative surgery was elevated in PSC-UC patients (hazard ratio [HR], 1.22; 95% confidence interval [CI], 1.02-1.44). Ileorectal anastomosis (IRA) was performed in 63% of the PSC-UC patients and 43% of the non-PSC-UC-patients, and the corresponding numbers for ileal pouch anal anastomosis (IPAA) were 35% and 53%. There was no significantly increased risk of failure following restorative surgery in PSC patients (HR, 1.44; 95% CI, 0.93-2.22). In PSC-UC patients, the cumulative failure rates following an IRA at 3 and 5 years were 15% and 18%, and following an IPAA they were 11% and 18%, respectively. Presence of PSC is not associated with the risk of colectomy, whereas the chance of restorative surgery in PSC-UC patients is higher than in UC alone.

    Full Text Available Abstract Background Ileal pouch-anal anastomosis (IPAA is the surgical procedure of choice for patients with refractory ulcerative colitis (UC and for familial adenomatous polyposis (FAP with many rectal polyps. Pouchitis is one of the more frequent complications after IPAA in UC patients; however, it is rare in FAP. Objective Evaluate pro-apoptotic activity in endoscopically and histological normal mucosa of the ileal pouch in patients with UC and FAP. Methods Eighteen patients (nine with UC and nine with FAP with J pouch after total rectocolectomy were studied. Biopsies were obtained from the mucosa of the pouch and from normal ileum. The specimens were snap-frozen and the expressions of Bax and Bcl-2 were determined by immunoblot of protein extracts and by immunohistochemistry analysis. FADD, Caspase-8, APAF-1 and Caspase-9 were evaluated by immunoprecipitation and immunoblot. Results Patients with UC had significantly higher protein levels of Bax and APAF-1, Caspase-9 than patients with FAP, but were similar to controls. The expressions of Bcl-2 and FADD, Caspase-8 were similar in the groups. Immunohistochemistry for Bax showed less intensity of immunoreactions in FAP than in UC and Controls. Bcl-2 immunostaining was similar among the groups. Conclusion Patients with FAP present lower levels of pro-apoptotic proteins in all methods applied, even in the absence of clinical and endoscopic pouchitis and dysplasia in the histological analysis. These findings may explain a tendency of up-regulation of apoptosis in UC patients, resulting in higher rates of progression to pouchitis in these patients, which could correlate with mucosal atrophy that occurs in inflamed tissue.

    Science.gov (United States)

    Bellera, Carolina L; Di Ianni, Mauricio E; Talevi, Alan

    2018-01-01

    Although the therapeutic arsenal against ulcerative colitis has greatly expanded (including the revolutionary advent of biologics), there remain patients who are refractory to current medications while the safety of the available therapeutics could also be improved. Molecular topology provides a theoretic framework for the discovery of new therapeutic agents in a very efficient manner, and its applications in the field of ulcerative colitis have slowly begun to flourish. Areas covered: After discussing the basics of molecular topology, the authors review QSAR models focusing on validated targets for the treatment of ulcerative colitis, entirely or partially based on topological descriptors. Expert opinion: The application of molecular topology to ulcerative colitis drug discovery is still very limited, and many of the existing reports seem to be strictly theoretic, with no experimental validation or practical applications. Interestingly, mechanism-independent models based on phenotypic responses have recently been reported. Such models are in agreement with the recent interest raised by network pharmacology as a potential solution for complex disorders. These and other similar studies applying molecular topology suggest that some therapeutic categories may present a 'topological pattern' that goes beyond a specific mechanism of action.

  2. Manipulation of the Endocannabinoid System in Colitis: A Comprehensive Review.

    Leinwand, Kristina L; Gerich, Mark E; Hoffenberg, Edward J; Collins, Colm B

    2017-02-01

    Inflammatory bowel disease (IBD) is a lifelong disease of the gastrointestinal tract whose annual incidence and prevalence is on the rise. Current immunosuppressive therapies available for treatment of IBD offer limited benefits and lose effectiveness, exposing a significant need for the development of novel therapies. In the clinical setting, cannabis has been shown to provide patients with IBD symptomatic relief, although the underlying mechanisms of their anti-inflammatory effects remain unclear. This review reflects our current understanding of how targeting the endocannabinoid system, including cannabinoid receptors 1 and 2, endogenous cannabinoids anandamide and 2-arachidonoylglycerol, atypical cannabinoids, and degrading enzymes including fatty acid amide hydrolase and monoacylglycerol lipase, impacts murine colitis. In addition, the impact of cannabinoids on the human immune system is summarized. Cannabinoid receptors 1 and 2, endogenous cannabinoids, and atypical cannabinoids are upregulated in inflammation, and their presence and stimulation attenuate murine colitis, whereas cannabinoid receptor antagonism and cannabinoid receptor deficient models reverse these anti-inflammatory effects. In addition, inhibition of endocannabinoid degradation through monoacylglycerol lipase and fatty acid amide hydrolase blockade can also attenuate colitis development, and is closely linked to cannabinoid receptor expression. Although manipulation of the endocannabinoid system in murine colitis has proven to be largely beneficial in attenuating inflammation, there is a paucity of human study data. Further research is essential to clearly elucidate the specific mechanisms driving this anti-inflammatory effect for the development of therapeutics to target inflammatory disease such as IBD.

    Ulcerative colitis (UC) is thought to originate from a disbalance in the interplay between the gut microbiota and the innate and adaptive immune system. Apart from the bacterial microbiota, there might be other organisms, such as parasites or viruses, that could play a role in the aetiology of UC.

    2011-02-01

    No previous study has explored the relationship between cytology and the frequency of behaviours associated with anal sac disease (ASD). The goals of the study were: (i) to compare the cytological findings between anal sac secretions from normal dogs with no history of ASD to those with non-neoplastic ASD; (ii) to determine whether anal sac cytological findings can be used to differentiate between normal dogs and dogs with ASD; (iii) to explore the correlation of anal sac cytology and behaviour between normal dogs and dogs with ASD; and (iv) to describe behaviours typical of ASD as reported by owners. Thirty dogs were selected for this study, based on their behavioural history as detailed in a questionnaire completed by their owners. Of the thirty dogs, ten were considered normal insofar as they had no history of ASD clinical signs. The remaining 20 dogs were characterized as having ASD, with a chronic history of perianal pruritus, but no other pruritus. All dogs had their anal sacs manually expressed, and the discharge was examined microscopically in a blinded manner. A total of 171 oil immersion fields (OIFs) were examined from normal dogs and 333 OIFs from dogs with ASD. The behavioural results for dogs with ASD revealed that scooting recurred with a median frequency of 3 weeks post-anal sac expression. There were no clinically statistically significant cytological differences between normal dogs and those with ASD, thereby leading to the conclusion that cytology is an ineffective tool for diagnosing ASD. © 2010 The Authors.

No colo uterino a associação de infecção por HPV (vírus do papiloma humano e ovos de Schistosoma em paciente HIV (vírus da imunodeficiência humana-positivo já foi relatada e há evidências de que essa associação possa alterar a história natural dessas doenças. Assim como no colo uterino, é possível que essa interação também ocorra na região anal. Nosso objetivo, portanto, é relatar um caso de condiloma anal em paciente HIV-positivo, que foi submetido a ressecção cirúrgica e que apresentou no exame histopatológico numerosos ovos de Schistosoma mansoni.Condilomata acuminata and Schistosoma eggs are frequently found in the anal region, but there is no report about the association of these diseases in this region. The association of HPV infection and Schistosoma eggs in an HIV-positive patient was found in uterine cervix and there is evidence suggesting that this association can alters the natural history of these diseases. Like in the cervix, it is possible that this interaction also occurs in the anal region. So, we report a case of anal Condilomata acuminata, in an HIV-positive patient, that was ressected and contained on histopathologic examination, multiple Schistosoma eggs.

    Full Text Available El artículo tiene como objetivo presentar una metodología alterna para el análisis de transcripciones de entrevistas semi-estructuradas considerando el paradigma cualitativo y aplicando la propuesta filosófica de la hermenéutica analógica impulsada por Beuchot (2009. Partiendo de una estrategia metodológica de Estudio de Caso, se describe en un primer momento, la contextualización y justificación del proyecto de investigación sobre la transformación estructural de la Universidad de Guanajuato (UG en México. Posteriormente se detalla el modelo de análisis hermenéutico aplicado a los textos surgidos de ocho entrevistas semiestructuradas realizadas con los principales actores que impulsaron, protagonizaron o se opusieron a este cambio organizacional, como rectores, diputados, profesores y funcionarios universitarios. A diferencia de un análisis cualitativo basado en la construcción de categorías y sub categorías identificadas en el texto de la entrevista, se explican las ventajas de un abordaje hermenéutico basado en una analogía, que nos permite mantener un equilibrio entre la univocidad y la equivocidad. La univocidad se entiende como una minería de la verdad, en donde uno y sólo un significado es válido y aceptable; y en el otro sentido, la equivocidad es entendida como una construcción interpretativa muy abierta que depende del contexto situacional o histórico de quien interpreta. La aplicación de esta metodología ha permitido la construcción de un referente analógico hermenéutico, conformado por un rango de interpretaciones válidas para este estudio de caso. Como resultado de esta metodología se presenta un mapa conceptual que integraesta gama de interpretaciones y se comentan las ventajas de tener este referente analógico no como una interpretación final sino como una herramienta para avanzar en un proceso hermenéutico continuo.

    Although radiation therapy is important in the treatment of tumors in pelvic and abdominal region, it may cause radiation injury as a side effect. But there is no effective way of preventing or curing the damages. The mechanism of acute radiation colitis has not been elucidated yet. Our previous reports have revealed that X-ray irradiation induce apoptosis of epithelial stem cells in colon. Then a hypothesis of the radiation colitis can be put forward, DNA damage by irradiation, apoptosis of mucosal epithelial stem cells and degeneration of epithelial gland structure, macrophages phagocyte the debris, being activated and secreting various inflammatory cytokines, infiltration of inflammatory cells. Several recent reports show that macrophages may play an important role in the process of inflammatory bowel diseases such ulcerative colitis or Crohn's disease. We studied radiation colitis using rat animal models. Male Wister rats were irradiated by a single fraction dose of 22.5 Gy X-ray at laparotomy, shielding except for an approximately 2.5 cm length of rectum. Histological changes and macrophage accumulation in the rectum mucosa were evaluated by immunohistochemistry and western blot method with the specimens which were taken on the 1, 2, 3, 4, 5, 6, 7, 10, and 14th day after irradiation. Severe macrophage accumulation in the lamina propria of the rectum was observed on the 5th day. At the same time, severe destruction of mucosal structure and inflammatory cells infiltration were also observed. Based on the potent pro-inflammatory cytokine producing effects of macrophage in rat and the increased expression in inflammatory bowel disease patients, speculate that intervention in the macrophage-cytokine network could form a future target for the treatment of acute radiation colitis.

    Full Text Available Aim: To review 12 cases of anovestibular fistula with normal anal opening. Methods: Retrospective analysis of 12 children with anovestibular fistula and normal anal opening were treated between the years 2000 and 2007. Of these, 11 patients were diagnosed as having acquired anovestibular fistula with normal anal opening and were managed by conservative management. Results: Most of them presented with diarrhea and labial redness. One patient was considered to have fistula of congenital origin and was managed surgically. Eleven patients presented between the ages of 1.5-11 months and were considered as cases of acquired anovestibular fistula and only two of them required surgical management in the form of colostomy and fistula excision. Others were successfully managed by conservative treatment; the fistulous output and labial redness decreased gradually within a period of 5-19 (average 11.5 days. Conclusions: Not all presentations of anovestibular fistula with normal anal opening can be considered as congenital. Presence of inflammation, paramedian fistula, and a favourable response to conservative management/colostomy suggest acquired etiology. Trial of conservative management should be given in the acquired variety.

    1983-09-01

    From 1966 to 1981, 47 patients with a diagnosis of anal carcinoma were irradiated. This group was composed of 23 males and 24 females, with age ranging from 38 to 84 years (average 64.4 years). Five patients were treated preoperatively and 34 were treated definitively with cancericidal doses of irradiation. Acute radiation reactions requiring a rest-break were noted in 28% of patients, but all were managed as outpatients without untoward chronic sequelae. Chronic complications were noted in 13 patients, including two patients who required colostomy for severe anal stenosis and two who required A-P resection for large painful ulcers. Twenty-eight of 35 patients (80%) treated with irradiation alone have remained locally controlled without further treatment. An additional four have been salvaged by surgery. Only three patients had interstitial implants as part of their treatment course. Actuarial survival at five years for the N/sub 0/ patients and the group as a whole are 95.6 and 79.3%, respectively. It is concluded that external beam irradiation alone, properly fractionated to cancericidal doses, can control anal carcinoma with acceptable morbidity rates and without the use of either chemotherapy or interstitial implants in most cases. There is also a strong correlation suggesting that anal intercourse and male homosexuality play a significant role in the etiology of this disease.

    Objective: To determine and evaluate the method of localization of anal verge by multislice spiral CT. To provide an imaging reference for operative guidance of low-rectal cancer. Methods Forty eight consecutive adult patients suspected of abnormalities other than rectal disease were evaluated with abdominal and pelvic CT scans since August, 2009. They were divided into two groups based on sex and age. There were 23 men and 25 women. The ages of young group were 28 to 50 years and the average age was 41 years. The ages of elderly group were 52 to 81 years and the average age was 64 years. A small cotton ball dipped with contrast media was put at the anal verge as a marker and CT scans were performed with 64-slice spiral CT scanner. The distances between the cotton balls and the lower margin of the pubis combination (La), the lower margin of the Sth sacral vertebra (Lb), the inferior aperture of minor pelvis (Lc) and the lower margin of the basement of external anal sphincter (Ld) were measured on the mid- sagittal images obtained by MPR. The averages, the standard deviations (s), the 95% and 80% confidence intervals of La, Lb, Lc and Ld were calculated. We took the intervals of ±1.96 s or ±1.28 s 0.05) between two different sex groups [male group, (10.0±1.2) mm], female group, (9.6±1.2) mm and between two age groups [young group, (9.6±1.2) mm, elderly group, (9.9±1.3) mm]. Conclusions: The lower margin of the basement of external anal sphincter was a useful anatomic landmark for localizing the anal verge, and could be definitely identified on the middle sagittal pelvic CT image. The distance between the structure and anal verge is constant enough and can be used in measuring distance from low rectal lesion to the anal verge. (authors)

  8. Fungal Colitis by Paracoccidioides brasiliensis: a case report

    Full Text Available Paracoccidioidomycosis (PBM is an infection caused by a dimorphic fungus called Paracoccidioides brasiliensis. It occurs in Latin America, with incidence of 1 to 3 per 100,000 inhabitants in endemic areas. The digestive tract is usually not affected, but when it occurs, it may lead to events similar to colorectal neoplasm and inflammatory bowel disease (IBD. This is a case report of a 68-year-old female patient, with diarrhea without blood or mucus for 6 months, weight loss of 8 kg over the period. Abdominal ultrasonography showed some mass in the right colon, suggestive of cancer and liver perihilar lymph node. Colonoscopy showed lesions suggestive of Crohn's disease. Biopsy showed chronic granulomatous colitis of fungal etiology: Paracoccidioidomycosis. The patient did not tolerate oral treatment with itraconazole and subsequently sulfadiazine, requiring hospital admission for the treatment with amphotericin B. The presence of Paracoccidioidomycosis in the digestive tract may be associated with bloody diarrhea, mucus, rectal hemorrhage, abdominal pain, malabsorption syndrome. Histopathological studies show the fungus and a chronic inflammatory infiltrate and granulation tissue. The differential diagnoses are tuberculosis, colorectal cancer and inflammatory bowel disease. The treatment is oral antifungal (itraconazole, sulfadiazine or intravenous (amphotericin B based. The case has caused diagnostic confusion between colon cancer (clinical and US and Crohn's disease (colonoscopy.Paracoccidioidomicose (PBM é uma infecção causada por um fungo dimórfico: Paracoccidioides brasiliensis.

    The early of pelvic irradiation on the anal sphincter has not been previously investigated. This study prospectively evaluated the acute effect of preoperative radiation on anal function. Twenty patients with rectal carcinoma received 4,500 cGy of preoperative external beam radiation. The field of radiation included the sphincter in 10 patients and was delivered above the anorectal ring in 10 patients. Anal manometry and transrectal ultrasound were performed before and four weeks after radiotherapy. No significant difference in mean maximal squeeze or resting pressure was found after radiation therapy. An increase in mean minimal sensory threshold was significant. Histologic examination revealed minimal radiation changes at the distal margin in 8 of 10 patients who underwent low anterior resection and in 1 of 3 patients who underwent abdominoperineal resection. The authors conclude that preoperative radiation therapy has minimal immediate effect on the anal sphincter and is not a major contributing factor to postoperative incontinence in patients after sphincter-saving operations for rectal cancer

  13. Tetraspanin CD9 Limits Mucosal Healing in Experimental Colitis

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Tetraspanins are a family of proteins with four transmembrane domains that associate between themselves and cluster with other partner proteins, conforming a distinct class of membrane domains, the tetraspanin-enriched microdomains (TEMs. These TEMs constitute macromolecular signaling platforms that regulate key processes in several cellular settings controlling signaling thresholds and avidity of receptors. In this study, we investigated the role of CD9, a tetraspanin that regulates major biological processes such as cell migration and immunological responses, in two mouse models of colitis that have been used to study the pathogenesis of inflammatory bowel disease (IBD. Previous in vitro studies revealed an important role in the interaction of leukocytes with inflamed endothelium, but in vivo evidence of the involvement of CD9 in inflammatory diseases is scarce. Here, we studied the role of CD9 in the pathogenesis of colitis in vivo. Colitis was induced by administration of dextran sodium sulfate (DSS, a chemical colitogen that causes epithelial disruption and intestinal inflammation. CD9−/− mice showed less severe colitis than wild-type counterparts upon exposure to DSS (2% solution and enhanced survival in response to a lethal DSS dose (4%. Decreased neutrophil and macrophage cell infiltration was observed in colonic tissue from CD9−/− animals, in accordance with their lower serum levels of TNF-α, IL-6, and other proinflammatory cytokines in the colon. The specific role of CD9 in IBD was further dissected by transfer of CD4+ CD45RBhi naive T cells into the Rag1−/− mouse colitis model. However, no significant differences were observed in these settings between both groups, ruling out a role for CD9 in IBD in the lymphoid compartment. Experiments with bone marrow chimeras revealed that CD9 in the non-hematopoietic compartment is involved in colon injury and limits the proliferation of epithelial cells. Our data indicate that CD9

    Although previous studies have suggested that appendix seems to be involved in the colitis, the role of this in the pathogenesis remains unclear. In this study, we assessed the importance of appendiceal lymphoid follicles, specifically the cecal patches (CP) in mice, using an experimental colitis model. Treatment with oxazolone resulted in ulcerations particularly at CP with follicular expansion as well as colitis. The colitis was attenuated by either appendectomy or the absence of mature B cells. We therefore established an intravital imaging system accompanied by the fluorescence resonance energy transfer technology to analyze the dynamic immune response of CP B cells. Our observation revealed frequent Ca 2+ signaling in CP B cells during the early phase of colitis development. These findings suggested that the CP B cells may be involved in the pathogenesis of colitis including inflammatory bowel diseases in humans. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Clostridium difficile colitis and cytomegalovirus colitis coinfection has been documented in immunocompromised patients. However, this kind of coinfection has rarely been reported in immunocompetent patients. We present a 90-year-old, critically ill, immunocompetent patient, who had a C. difficile and cytomegalovirus colitis coinfection. Although the common risk factors of both types of colitis are well known, clinical physicians still need to be alert to this coinfection because severe complications of CMV colitis have been reported previously. Physicians should be more aggressive in the management of elderly immunocompetent patients with refractory symptoms of colitis.

    Clostridium difficile infection (CDI) frequently complicates ulcerative colitis (UC) and can mimic disease flare. Differentiating UC flare from CDI remains a clinical challenge, particularly due to C. difficile colonization. Procalcitonin (PCT) is a serum biomarker for bacterial infections. We hypothesized that PCT would differentiate acute CDI from UC flare and C. difficile colonization. A single-center prospective cohort study was conducted from 2013 to 2016. All UC patients with a stool sample for C. difficile testing were eligible. A total of 117 patients were enrolled, while 20 were excluded. Chart review was performed. Among 27 patients with CDI, median PCT was 60.7 (range 26-560.6) pg/mL, while among 90 patients without CDI, median PCT was 56.7 (range 25.1-2,252) pg/mL (p = 0.9). It was found that 14 patients with CDI responded completely to C. difficile treatment (CDI-R), while 8 patients did not and were diagnosed with UC flare (CDI-NR). For CDI-R, median PCT was 104.5 (range 26.3-560.6), compared to 40.3 (range 26.0-116.3) for CDI-NR (p = 0.036). In UC patients presenting with diarrhea, serum PCT was not significantly higher in UC patients with positive C. difficile testing. However, PCT was significantly elevated in CDI-R versus CDI-NR, suggesting that PCT may have utility in making this discrimination. © 2017 S. Karger AG, Basel.

  19. Testing for and the role of anal and rectal sensation.

    Science.gov (United States)

    Rogers, J

    1992-03-01

    The rectum is insensitive to stimuli capable of causing pain and other sensations when applied to a somatic cutaneous surface. It is, however, sensitive to distension by an experimental balloon introduced through the anus, though it is not known whether it is the stretching or reflex contraction of the gut wall, or the distortion of the mesentery and adjacent structures which induces the sensation. No specific sensory receptors are seen on careful histological examination of the rectum in humans. However, myelinated and non-myelinated nerve fibres are seen adjacent to the rectal mucosa, but no intraepithelial fibres arise from these. The sensation of rectal distension travels with the parasympathetic system to S2, S3 and S4. The two main methods for quantifying rectal sensation are rectal balloon distension and mucosal electrosensitivity. The balloon is progressively distended until particular sensations are perceived by the patient. The volumes at which these sensations are perceived are recorded. Three sensory thresholds are usually defined: constant sensation of fullness, urge to defecate, and maximum tolerated volume. The modalities of anal sensation can be precisely defined. Touch, pain and temperature sensation exist in normal subjects. There is profuse innervation of the anal canal with a variety of specialized sensory nerve endings: Meissner's corpuscles which record touch sensation, Krause end-bulbs which respond to thermal stimuli, Golgi-Mazzoni bodies and pacinian corpuscles which respond to changes in tension and pressure, and genital corpuscles which respond to friction. In addition, there are large diameter free nerve endings within the epithelium. The nerve pathway for anal canal sensation is via the inferior haemorrhoidal branches of the pudendal nerve to the sacral roots of S2, S3 and S4. Anal sensation may be quantitatively measured in response to electrical stimulation. The technique involves the use of a specialized constant current generator

Na população geral a incidência é de 1 em 100.000 habitantes, e entre os homens que fazem sexo com homens essa incidência atinge 35 por 100.000 habitantes, sendo que os portadores de HIV têm esse risco duplicado (70 por 100.000 habitantes. MÉTODO: Foi realizada revisão da literatura com consulta nos periódicos das bases Medline/Pubmed, Scielo e Lilacs cruzando os descritores Rastreamento, Lesões pré-cancerosas, Neoplasias do ânus e HIV. Além da revisão bibliográfica, foi adicionada a este trabalho a experiência pessoal dos autores, e a obtida no Departamento de Gastroenterologia - Divisão Cirúrgica, no ICESP - Instituto do Câncer do Estado de São Paulo Octávio Frias de Oliveira, no Departamento de Moléstias Infeciosas - Casa da AIDS e no Serviço de Coloproctologia do Hospital das Clínicas da Universidade de São Paulo, SP, Brasil. CONCLUSÕES: HIV+ é um grande fator de risco no desenvolvimento de carcinoma espino-celular anal em indivíduos infectados por HPV. A avaliação desses pacientes não deve se restringir à erradicação de condilomas, mas principalmente incluir o rastreamento de lesões displásicas subclínicas potencialmente neoplásicas. Apesar dos métodos de rastreamento ainda não serem ideais, o grande benefício do rastreamento baseia-se no fato de oferecer acompanhamento rigoroso, tornando possível à prevenção ou detecção cada vez mais precoce do carcinoma espino-celular anal.INTRODUCTION: Squamous cell carcinoma of the anal canal is a disease that affects the middle-aged adults and accounts for 4% of cancers of the gastrointestinal tract below.

    Six patients each with an extensive ulcerating colitis are reported. Common features were a febrile nonbloody diarrhea; radiological involvement of the whole colon with superficial ulcerations and preservation of haustra, and integrity of the terminal ileum and rectum; the absence of any specific pathological finding; and, most important, the spontaneous recovery of the lesions in the absence of any treatment except sympatomatic measures. The present follow up after recovery range from 18 months to 5 years. Four cases were young women taking oral contraceptives and two patients were older. These patients with colitis could represent a new entity or could be a particular form of Crohn's disease of the colon, with delayed diagnostic pathological features.

Its a benign condition, which arises from anthraquinone laxative abuse and has no symptoms of its own. The main importance of diagnosing Melanosis Coli correctly lies in the fact that if its extensive, there may be difficulty in differentiating it from ischemic colitis. Case presentation We present a case of extensive Melanosis Coli involving the whole of large bowel that appeared gangrenous. A sub total colectomy was performed on presumed diagnosis of ischemic bowel. Conclusion This report reminds the clinicians that extensive Melanosis Coli may mimic ischemic colitis and thus must be considered as a differential diagnosis.

    2015-07-01

    Ulcerative colitis (UC) is a representative clinical manifestation of inflammatory bowel disease that causes chronic gastrointestinal tract inflammation. Dextran sulfate sodium (DSS)-induced colitis mice have been used to investigate UC pathogenesis, and in this UC model, disturbance and impairment of the mucosal epithelium have been reported to cause colitis. However, how DSS sporadically breaks down the epithelium remains unclear. In this study, we focused on the colonic microcirculation and myenteric neurons of DSS-induced colitis. Moreover, we examined the potential of myenteric neurons as a target to prevent exacerbation of colitis. Fluorescent angiographic and histopathological studies revealed that DSS administration elicited blood vessel disruption before epithelial disorders appeared. Ischemic conditions in the lamina propria induced inducible nitric oxide synthase (iNOS) expression in myenteric neurons as colitis aggravated. When neuronal activity was inhibited with butylscopolamine, neuronal iNOS expression decreased, and the exacerbation of colitis was prevented. These results suggested that DSS-induced colitis was triggered by microcirculatory disturbance in the mucosa, and that excessive neuronal excitation aggravated colitis. During remission periods of human UC, endoscopic inspection of the colonic microcirculation may enable the early detection of disease recurrence, and inhibition of neuronal iNOS expression may prevent the disease from worsening.

    Full Text Available Objective: endoanal ultrasonography can detect organic causes of anal pain without pathology on physical examination. The aim of this study is to evaluate the importance of endoanal ultrasonography in the diagnosis and therapeutic management of idiopathic and functional anal pain. Material and methods: retrospective study, between 15 March 2005 and 15 June 2008, of all patients with proctalgia and normal examination or with alterations not responsible for anal pain at proctologic exam that have undergone an endoanal ultrasonography. Results: a total of 90 patients were analyzed, with a mean age of 50.5 years, 58% were female. Twenty-three patients had functional anal pain clinic criteria. Endoanal ultrasonography revealed alterations in 49% of patients. The primary findings were changes in sphincters in 14 patients, followed by anal sepsis in 12 patients, anal fissure in 10 patients, perirectal lesions in 6 patients and ulcer of the anal canal in 2 patients. Of the patients with sphincter defects, 5 patients had criteria of chronic anal pain. In this group of patients, no differences were found in manometric and defecographic results between the different ultrasound abnormalities. Conclusions: the endoanal ultrasonography detected occult organic lesions to proctologic examination, in half the patients with anal pain. Ultrasound abnormalities were found in 22% of patients with functional anal pain. However, there was no correlation between ultrasound findings and physiological studies, and therefore could not find etiological or pathogenic factors of functional anal pain.Objetivo: la ecografía endoanal puede detectar causas orgánicas en el dolor anal sin patología en la exploración física.

    Full Text Available Management guidelines offer clinicians clear, evidence-based and often succinct treatment advice. For ulcerative colitis these guidelines describe the use of 5-ASA, corticosteroids, thiopurines, cyclosporine, and anti-TNFα therapies. However, guidelines do have some drawbacks, mainly a lack of concrete advice concerning patients resistant to these aforementioned therapies. This review gives a short overview of current guidelines and addresses treatment alternatives for conventional therapies.

Our results suggest that the combined use of optical coherent tomography (OCT and fluorescence diagnosis helps to refine the nature and boundaries of the pathological process in the tissue of the colon in ulcerative colitis. Studies have shown that an integrated optical diagnostics allows us to differentiate lesions respectively to histology and to decide on the need for biopsy and venue. This method is most appropriate in cases difficult for diagnosis.

    Proresolution functions were reported for PGD2 in colitis, but the role of its two receptors, D-type prostanoid (DP) and, in particular, chemoattractant receptor homologous molecule expressed on Th2 cells (CRTH2), is less well defined. We investigated DP and CRTH2 expression and function during human and murine ulcerative colitis (UC). Expression of receptors was measured by flow cytometry on peripheral blood leukocytes and by immunohistochemistry and immunoblotting in colon biopsies of patients with active UC and healthy individuals. Receptor involvement in UC was evaluated in a mouse model of dextran sulfate sodium colitis. DP and CRTH2 expression changed in leukocytes of patients with active UC in a differential manner. In UC patients, DP showed higher expression in neutrophils but lower in monocytes as compared with control subjects. In contrast, CRTH2 was decreased in eosinophils, NK, and CD3(+) T cells but not in monocytes and CD3(+)/CD4(+) T cells. The decrease of CRTH2 on blood eosinophils clearly correlated with disease activity. DP correlated positively with disease activity in eosinophils but inversely in neutrophils. CRTH2 internalized upon treatment with PGD2 and 11-dehydro TXB2 in eosinophils of controls. Biopsies of UC patients revealed an increase of CRTH2-positive cells in the colonic mucosa and high CRTH2 protein content. The CRTH2 antagonist CAY10595 improved, whereas the DP antagonist MK0524 worsened inflammation in murine colitis. DP and CRTH2 play differential roles in UC. Although expression of CRTH2 on blood leukocytes is downregulated in UC, CRTH2 is present in colon tissue, where it may contribute to inflammation, whereas DP most likely promotes anti-inflammatory actions.

    We report a case of isolated gastrointestinal metastasis from breast lobular carcinoma, which mimicked primary anal cancer. In July 2000, an 88-year-old woman presented with infiltrating lobular cancer (pT1/G2/N2). The patient received postoperative radiotherapy and hormonal therapy. Four years later, she presented with an anal polypoid lesion. The mass was removed for biopsy. Immunohistochemical staining suggested a breast origin. Radiotherapy was chosen for this patient, which resulted in complete regression of the lesion. The patient died 3 years after the first manifestation of gastrointestinal metastasis. According to the current literature, we consider the immunohistochemistry features that are essential to support the suspicion of gastrointestinal breast metastasis, and since we consider the gastrointestinal involvement as a sign of systemic disease, the therapy should be less aggressive and systemic.

    Persistent activation of the inflammatory response contributes to the development of inflammatory bowel diseases, which increase the risk of colorectal cancer. We aimed to identify microRNAs that regulate inflammation during the development of ulcerative colitis (UC) and progression to colitis-associated colon cancer (CAC). We performed a quantitative polymerase chain reaction analysis to measure microRNAs in 401 colon specimens from patients with UC, Crohn's disease, irritable bowel syndrome, sporadic colorectal cancer, or CAC, as well as subjects without these disorders (controls); levels were correlated with clinical features and disease activity of patients. Colitis was induced in mice by administration of dextran sodium sulfate (DSS), and carcinogenesis was induced by addition of azoxymethane; some mice also were given an inhibitor of microRNA214 (miR214). A high-throughput functional screen of the human microRNAome found that miR214 regulated the activity of nuclear factor-κB. Higher levels of miR214 were detected in colon tissues from patients with active UC or CAC than from patients with other disorders or controls and correlated with disease progression. Bioinformatic and genome-wide profile analyses showed that miR214 activates an inflammatory response and is amplified through a feedback loop circuit mediated by phosphatase and tensin homolog (PTEN) and PDZ and LIM domain 2 (PDLIM2). Interleukin-6 induced signal transducer and activator of transcription 3 (STAT3)-mediated transcription of miR214. A miR214 chemical inhibitor blocked this circuit and reduced the severity of DSS-induced colitis in mice, as well as the number and size of tumors that formed in mice given azoxymethane and DSS. In fresh colonic biopsy specimens from patients with active UC, the miR214 inhibitor reduced inflammation by increasing levels of PDLIM2 and PTEN. Interleukin-6 up-regulates STAT3-mediated transcription of miR214 in colon tissues, which reduces levels of PDLIM2 and PTEN

    Female sex workers have been disproportionately affected with HIV and anal sexual experience elevate their vulnerability. Anal intercourse has more risk of HIV transmission than vaginal intercourse for receptors that coupled with low condom and proper lubricant use behavior during anal sex. Besides majority of them did not understand HIV transmission risk of anal intercourse. In Ethiopia, studies on anal sexual experience is almost none existent, so the purpose of this study is to explored anal sexual experience and HIV transmission risk awareness among female sex worker in Dire Dawa, Eastern Ethiopia. Qualitative study with thematic analysis approach was conducted among 18 female sex workers and recruitment of study participants performed until saturation of information. The principal investigator conducted in-depth interviews using local language (Amharic) and it was recorded on audio recorder. Tape recorded data was transcribed and translated to English and entered into open code version 3.4 for coding and theme identification. Data collection conducted simultaneously with data analysis. Female sex workers practiced anal sex for different themes like financial influence, coercion, intentionally, peer pressure and as a sign of intimacy and love. Coercion, negative attitudes, poor awareness about HIV transmission risks of anal sex and protection capacity of condom and proper lubricants are the identified themes for not using condom and proper lubricants during anal sex by female sex workers. Inaccessibility and unavailability of health services for issues related to anal sex was the core reason for female sex workers' misperception and risk anal sexual experience. Female sex workers practiced anal sex without risk reduction approaches and they did not understand exacerbated risk of anal sex to HIV transmission. Stakeholders including ministry of health need to incorporate potential awareness raising tasks and programs about risk of anal sex and methods of risk

    The incidence and prevalence of inflammatory bowel disease (IBD) has increased in recent years in several Latin American countries. There is a need to raise awareness in gastroenterologists and the population in general, so that early diagnosis and treatment of ulcerative colitis (UC) and Crohn's Disease (CD) can be carried out. It is important for all physicians to have homogeneous criteria regarding the diagnosis and treatment of IBD in Latin America. The Pan American Crohn's and Colitis Organisation (PANCCO) is an organization that aims to include all the countries of the Americas, but it specifically concentrates on Latin America. The present Consensus was divided into two parts for publication: 1) Diagnosis and treatment and 2) Special situations. This is the first Latin American Consensus whose purpose is to promote a perspective adapted to our Latin American countries for the diagnosis, treatment, and monitoring of patients with UC and CD.

    Currently, several noninvasive modalities, including MRI and PET, are being investigated to identify early intestinal inflammation, longitudinally monitor disease status, or detect dysplastic changes in patients with inflammatory bowel disease. Here, we assess the applicability and utility of multispectral optoacoustic tomography (MSOT) in evaluating the presence and severity of colitis. Methods: C57B/6 mice were untreated or treated with Bacteroides fragilis and antibiotic-mediated depletion of intestinal flora to initiate colitis. Mice were imaged using MSOT to detect intestinal inflammation. Intestinal inflammation identified with MSOT was also confirmed using both colonoscopy and histology. Results: Mice with bacterial colitis demonstrated a temporally associated increase in mesenteric and colonic vascularity with an increase in mean signal intensity of oxygenated hemoglobin ( P = 0.004) by MSOT 2 d after inoculation. These findings were significantly more prominent 7 d after inoculation, with increased mean signal intensity of oxygenated hemoglobin ( P = 0.0002) and the development of punctate vascular lesions on the colonic surface, which corresponded to changes observed on colonoscopy as well as histology. Conclusion: With improvements in depth of tissue penetration, MSOT may hold potential as a sensitive, accurate, noninvasive imaging tool in the evaluation of patients with inflammatory bowel disease. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

    Inflammatory bowel disease (IBD) is a chronically relapsing inflammatory disorder of the gastrointestinal tract. Most IBD treatments are unsatisfactory; therefore, various dietary supplements have emerged as promising interventions. Laminaria japonica (LJ) is an edible seaweed used to regulate digestive symptoms. Probiotics have been reported to improve digestive problems and their simultaneous administration with seaweeds has been shown to produce synergistic therapeutic effects. Here, we investigated the effect of LJ combination with probiotics on dextran sodium sulfate-induced colitis model in mice. Aqueous LJ extracts (LJE) at doses from 100 to 300 mg/kg and probiotics at a dose of 300 mg/kg were orally administered for 7 days. Body weight, colon length, histological score, macroscopic damage, and the levels of cytokines IFN- γ , IL-1 β , IL-6, IL-10, IL-12 (P40), IL-12 (P70), IL-17, and TNF- α were assessed. LJE alone caused a significant improvement of colitis signs such as colon length, histological score, and IL-1 β and IL-6 production. LJE and probiotics demonstrated a synergistic effect by the histological score and levels of IL-1 β , IL-6, and IL-12 (P40) but not IFN- γ , IL-10, and IL-12 (P70). In conclusion, LJE was effective in inducing protection against colitis in mice and acted synergistically with probiotics.

    The pharmacological therapy for inflammatory bowel diseases continues to be problematic, and requires new alternative options. In this study, we tested the hypothesis that carvacrol (CAR), a phenolic monoterpene with anti-inflammatory and antioxidant activities, can treat experimental colitis in mice. C57BL/6 mice (n=8/group) were subjected to intrarectal administration of acetic acid (5%) to induce colitis. Mice were pretreated with CAR (25, 50 or 100mg/kg, p.o.) every 12h for three days prior to the induction. Abdominal hyperalgesia, macroscopic and microscopic colon damage, myeloperoxidase (MPO) activity, tumor necrosis factor (TNF)-α and interleukin (IL)-1β levels, oxidative stress markers, and antioxidant enzyme activities were evaluated. Pretreatment with all doses of CAR significantly decreased abdominal hyperalgesia and colon MPO activity and TNF-α and IL-1β levels. A reduction in macroscopic and microscopic damage (p<0.05) was observed at doses of 50 and 100mg/kg CAR. Pretreatment with CAR significantly reduced lipid peroxidation (for all doses) and increased sulfhydryl groups (at 100mg/kg). This effect was accompanied by a significant increase in catalase, superoxide dismutase, and glutathione peroxidase activities. These findings indicate that CAR protected mice from acetic acid-induced colitis by reducing inflammatory, nociceptive, and oxidative damages. Copyright © 2017 Elsevier Masson SAS.

    Full Text Available One of the most common causes of chronic diarrhea is ascribed to microscopic colitis (MC. MC is classified in subtypes: collagenous colitis (CC and lymphocytic colitis (LC. Patients with MC report watery, non-bloody diarrhea of chronic course, abdominal pain, weight loss, and fatigue that may impair patient’s health-related quality of life. A greater awareness, and concomitantly an increasing number of diagnoses over the last years, has demonstrated that the incidence and prevalence of MC are on the rise. To date, colonoscopy with histological analysis on multiple biopsies collected along the colon represents the unique accepted procedure used to assess the diagnosis of active MC and to evaluate the response to medical therapy. Therefore, the emerging need for less-invasive procedures that are also rapid, convenient, standardized, and reproducible, has encouraged scientists to turn their attention to the identification of inflammatory markers and other molecules in blood or feces and within the colonic tissue that can confirm a MC diagnosis. This review gives an update on the biomarkers that are potentially available for the identification of inflammatory activity, related to CC and LC.

    2014-12-01

    The management of Crohn's disease and ulcerative colitis has become increasingly complex. With the current utilization of immunosuppressive therapies earlier in the disease course for patients presenting with moderate to severe disease, there is a great need for additional biologic agents targeting inflammatory mediators other than anti-tumor necrosis factor-α (anti-TNF) agents. Although anti-TNF agents have positively impacted the treatment of inflammatory bowel disease, many patients can lose their response or develop intolerance to these agents over time through the formation of antidrug antibodies. Furthermore, a sizeable percentage of patients are primary nonresponders to anti-TNF drugs. Vedolizumab (Entyvio, Takeda Pharmaceuticals), a monoclonal antibody to the α4β7 integrin, inhibits gut lymphocyte trafficking and has been demonstrated to be an effective and safe agent for the treatment of both Crohn's disease and ulcerative colitis. This article reviews the clinical trial evidence and rationale for the use of vedolizumab in moderate to severe Crohn's disease and ulcerative colitis.

    Diverse T help (Th) cells play a crucial role in the processing and maintaining of chronic inflammation as seen in ulcerative colitis (UC). Th9, a novel subset of Th cells that primarily produces interleukin (IL)-9, has recently been associated with the development of inflammatory diseases. In this study, we evaluated the presentation of Th9 cells in inflamed tissues of human and experimental mouse UC, and examined the therapeutic efficiency of anti Th9 cytokine IL-9 in the experimental mouse UC. Using immunohistochemistry (IHC), we evaluated the presentation of Th9 cells labelled by transcriptional factor PU.1 in both human and dextran sulfate sodium (DSS) induced mouse colitis biopsies. The results showed that increased PU.1 positive Th9 cells were mainly located in the lamina propria in relative with the controls, intraepithelial Th9 cells can also be observed but at low density. Double IHCs revealed that most of PU.1 positive cells were CD3 positive lymphocytes in human UC specimens. Anti-IL-9 antibody injection for 2 weeks reduced the severity of inflammation in DSS induced colitis mice. Our results suggest that The Th9/IL-9 is involved in the pathogenesis of UC.

    MRI of the pelvis was performed in 17 children following surgical correction of anal and rectal atresias and in five children without ano-rectal malformations. A muscle score was used to characterize the muscles of the pelvic floor and their relationship to the rectum. There was close agreement between the MRI muscle score and clinical continence. MRI provided additional information that should improve continence following conservative and surgical treatment. (orig.) [de

    Obstetric anal sphincter injury is common but the effect on body image is unreported. The aim of this study was to explore patient perceived changes in body image and other psychological aspects in women attending a perineal follow-up clinic. This retrospective study analysed women's responses to a self-reported questionnaire. Consecutive women with anal sphincter injury who attended a United Kingdom Maternity Hospital perineal follow-up clinic between January 1999 and January 2012 were identified and the records obtained and reviewed. Multivariate regression analyses were performed to examine variables influencing self-reported change in body image. Questionnaires and operation notes were analysed from 422 women who attended at a median of four months after delivery. 222 (53%) reported a change in body image with 80 (19%) reporting lower self-esteem and 75 (18%) a change in their personality due to the change in body image. 248 (59%) perceived an anatomical change due to the delivery. Factors associated with increased likelihood of reporting a change in body image were reporting a perceived change in anatomy due to the delivery, adjusted OR 6.11 (3.56-10.49), anal incontinence, OR 1.97 (1.16-3.36), and delivery by forceps, OR 2.59 (1.23-5.43). This is the first study to quantify body image changes in women after anal sphincter injury sustained in childbirth. These were found to be very common, affecting up to 50% of women. The study has several limitations but it does highlight the significant psychosocial problems of negative self-esteem and personality changes associated with a perceived change in body image that has not previously been reported. It also outlines the further research questions that need to be addressed. Copyright © 2017 Elsevier B.V. All rights reserved.

    Background. The aim of the study was to visualize, by anal ultrasound (AUS), the suspected defects of the anal sphincters in the patients after colostomy and to analyze possible factors that could have led to such defects. Patients and methods. AUS, using a 7.0 MHz endorectal probe, was performed in a group of 25 patients with colostomy. The internal anal sphincter (IAS), external anal sphincter (EAS) and puborectalis muscle (PR) were visualized and the defects within them were qualified and quantified. For statistical analysis, the analysis of variance (ANOVA) was used. Results. The IAS was thin in all but three patients (22 patients; 88 %) with the mean thickness of 1.62 mm. A circular reduction of the thickness along the entire length of the IAS was seen in 20 patients (90.9 %). The echogenicity of the IAS was increased in 15 patients (60 %), and in 10 of them (66.6%), this defect embraced the whole length and circumference of the IAS. The margins of the IAS were not well-defined in 10 patients (40%). A significant correlation was found between the length of the patient's life with the stoma and the IAS echogenicity defect (p-value = 0.0001). No significant correlation was found between the dynamic examination, the IAS thickness and the IAS borders definition. Conclusion. The reduced thickness, increased echogenicity and borders definition defect of the IAS are seen in the patients after colostomy. The only significant correlation was confirmed between the length of the patient's life with the stoma and the IAS echogenicity defect. (author)

    Full Text Available The aim of this study was to investigate the clinical characteristics, treatment outcomes and psychological distress in patients with chronic idiopathic anal pain. The study was conducted on patients referred to Hangzhou Third Hospital for chronic anal pain from January, 2010 to December, 2014. Patient demographics, clinical history, anorectal physiology, and radiological imaging data were recorded for all patients. The treatment outcome was noted for patients treated and followed up for more than 6 month at the present unit. Ninety-six patients with mean age of 45.1 years (range, 17-82 were studied. Seventy-one patients (74.0% had functional anorectal pain(FARP. The main complaints were dull, sharp, stabbing, or spasm pain. Among all patients, 34.3% reported that their pain radiated into other locations. Fifty-one patients (53.1% had bowel dysfunction, while 28.1% patients had urinary dysfunction. The common factors associated with pain relief were day time, lying down and warm water baths; the factors that contributed to aggravated pain were night time, defecation or sitting. 92.7% (89/96 of patients reported symptoms of psychological disturbance. FARP patients exhibited increased depression than non-FARP patients(P<0.05. In addition, female patients were more likely to have depression than male patients (P<0.05. The overall pain treatment success rate was 55.2% (53/96. The pain treatment outcome was better in non-FARP patients than in FARP patients(χ2=3.85, P<0.05. Conclusively, chronic idiopathic anal pain is a complex clinical symptom, involving pelvic floor muscles, the nervous system, endocrine system, and the patients’ psychological conditions. Further research is needed to improve diagnosis and treatment for patients with chronic idiopathic anal pain.

    Since 1980, curative-intent radiation therapy of epidermoid carcinoma of the anal canal is the standard first line treatment. The combined concomitant chemotherapy and radiation therapy is presently established for locally advanced tumors more than 4 cm in length and/or with nodal involvement. We report the Tenon hospital experience since 1972 concerning the long term results after radiation therapy, the modifications of the radiation technique, and the evolution of treatment strategy.

    To identify Spanish funded paediatric research published in general paediatric journals included in the Web of Science (WoS) from 2010 to 2014) and those published in the Anales de Pediatría. To examine the relationship between funding and the prestige of the journals. To describe the journal conditions to meet the open access criteria. Spanish funded paediatric articles (FA) were identified by using the WoS Funding Agency field, and by reviewing the original documents for the Anales de Pediatria (AP). For the FA published in AP the number and kind of funding agencies were identified. The possible differences in citations between FA and non-funded was assessed for articles published in this journal using the Kruskal-Wallis non-parametric test. For general journals, the patterns of distribution of FA and non-FA were investigated according to the quartile of the journal. The journal's self-archiving conditions were described using Sherpa/romeo database. Funding was received for 27.5%, being 16.6% for those published in AP. In these, 105 funding agencies were identified, with 80% being national. The FA published in AP did not receive significantly more citations. In general journals, the presence of FA is greater in Q1 and Q2 journals. More than half (56%) of articles were published in subscription journals. All journals that publish FA allow self-archiving in repositories, but with embargos of at least 12 months. The role of AP in the dissemination of FA is still limited. Embargos in self-archiving permits compliance of Spanish open access mandate, but may hinder compliance in Europe. Copyright © 2016 Asociación Española de Pediatría.

    HIV-positive MSM are at increased risk for developing anal squamous cell carcinoma. Detection of precursor lesions of anal cancer [anal high-grade squamous intraepithelial lesions (HSIL)] is cumbersome and expensive. Our objective was to identify potential risk factors for anal HSIL in HIV-positive

    SSc is a connective tissue, multisystem disorder of unknown aetiology. The gastrointestinal tract (GIT) is affected in up to 90% of patients. The exact pathophysiology of GIT involvement is not known, but it is related to both neurogenic and myogenic abnormalities as well as possible vascular and ischaemic changes. Thinning of the internal anal sphincter (IAS) has been demonstrated in SSc with faecal incontinence. We aimed to investigate anal sphincter structure in patients with SSc. Forty-four SSc patients [24 symptomatic (Sx) and 20 asymptomatic (ASx)] and 20 incontinent controls (ICs) were studied. Patients underwent anorectal manometry and endoanal US. In the ICs, external anal sphincter defects were more common, but the IAS was less atrophic, evident by both atrophy scores and IAS thickness. There was no significant difference in atrophy scores [Sx: 2 (1.5-3) vs ASx: 2 (1-2)] or IAS thickness [Sx: 1.85 (1.5-2.3) vs ASx: 1.8 (1.7-2.25)] between the Sx and ASx SSc patients. Patients with SSc (both Sx and ASx) have thin and atrophic IAS, suggesting that IAS atrophy develops even in ASx patients and this may be amenable to treatment with sacral neuromodulation.

    This paper presents a numerical investigation of the thermal behavior of an artificial anal sphincter using shape memory alloys (SMAs) proposed by the authors. The SMA artificial anal sphincter has the function of occlusion at body temperature and can be opened with a thermal transformation induced deformation of SMAs to solve the problem of severe fecal incontinence. The investigation of its thermal behavior is of great importance in terms of practical use in living bodies as a prosthesis. In this work, a previously proposed phenomenological model was applied to simulate the thermal responses of SMA plates that had undergone thermally induced transformation. The numerical approach for considering the thermal interaction between the prosthesis and surrounding tissues was discussed based on the classical bio-heat equation. Numerical predictions on both in vitro and in vivo cases were verified by experiments with acceptable agreements. The thermal responses of the SMA artificial anal sphincter were discussed based on the simulation results, with the values of the applied power and the geometric configuration of thermal insulation as parameters. The results obtained in the present work provided a framework for the further design of SMA artificial sphincters to meet demands from the viewpoint of thermal compatibility as prostheses.

    The purpose of this work is to evaluate the electromyography value of anal sphincter in patients with anorectal dysfunctions. Anorectal dysfunctions are frequent reason of pediatric consultation in children, especially with anal incontinence. A study of series of cases in patient with anorectal dysfunctions was carried out from January 2002 to January of 2006. 65 patients were studied. Anorectal malformations (ARM) represented the predominant affection with 38 patients (58.5%), prevailing the male sex in 25 patients (65.8%). Encopresis and intestinal agagliosis dicrease was observed. Sphincter was found before surgical treatment through electromyography in patients with anorectal malformations and colostomy; in those with definitive operation and open colostomy, it avoided the operation in a patient that did not have muscular activity of the external sphincter. In children already operated and with closed colostomy several electromyography changes were observed in correspondence with different incontinence grades. In encopresis cases the study was useful to rule out sphincter functional alterations. Electromyography was pathological in all the operated patients of intestinal aganglionosis. This procedure was very useful for anal incontinence study that helped to determine and establish the prognosis. (author)

    Research Highlights: Human papillomaviruses cause anal intraepithelial neoplasia (AIN). Digital image processing was carried out to classify the grades of AIN quantitatively. The fractal dimension as well as grey value statistics was calculated. Higher grades of AIN yielded higher values of the fractal dimension. An automatic detection system is feasible. - Abstract: It is well known that human papillomaviruses (HPV) induce a variety of tumorous lesions of the skin. HPV-subtypes also cause premalignant lesions which are termed anal intraepithelial neoplasia (AIN). The clinical classification of AIN is of growing interest in clinical practice, due to increasing HPV infection rates throughout human population. The common classification approach is based on subjective inspections of histological slices of anal tissues with all the drawbacks of depending on the status and individual variances of the trained pathologists. Therefore, a nonlinear quantitative classification method including the calculation of the fractal dimension and first order as well as second order image statistical parameters was developed. The absolute values of these quantitative parameters reflected the distinct grades of AIN very well. The quantitative approach has the potential to decrease classification errors significantly and it could be used as a widely applied screening technique.

    Herpesvirus infections often complicate the clinical course of patients with inflammatory bowel disease; however, invasive disease due to herpes simplex virus is distinctly uncommon. We present a case of herpes simplex virus colitis and hepatitis, review all the previously published cases of herpes simplex virus colitis, and discuss common clinical features and outcomes. We also discuss the epidemiology, clinical manifestations, diagnosis, and management of herpes simplex virus infections, focusing specifically on patients with inflammatory bowel disease. A 43-year-old man with ulcerative colitis, previously controlled with an oral 5-aminosalicylic agent, developed symptoms of a colitis flare that did not respond to treatment with systemic corticosteroid therapy. One week later he developed orolabial ulcers and progressive hepatic dysfunction, with markedly elevated transaminases and coagulopathy. He underwent emergent total colectomy when imaging suggested bowel micro-perforation. Pathology from both the colon and liver was consistent with herpes simplex virus infection, and a viral culture of his orolabial lesions and a serum polymerase chain reaction assay also identified herpes simplex virus. He was treated with systemic antiviral therapy and made a complete recovery. Disseminated herpes simplex virus infection with concomitant involvement of the colon and liver has been reported only 3 times in the published literature, and to our knowledge this is the first such case in a patient with inflammatory bowel disease. The risk of invasive herpes simplex virus infections increases with some, but not all immunomodulatory therapies. Optimal management of herpes simplex virus in patients with inflammatory bowel disease includes targeted prophylactic therapy for patients with evidence of latent infection, and timely initiation of antiviral therapy for those patients suspected to have invasive disease.

    Microscopic colitis (MC), comprising collagenous colitis (CC) and lymphocytic colitis (LC), is a type of variation of inflammatory bowel diseases. Local T-cell infiltration in the mucosa plays a major role in MC immunopathology. To understand diversity and clonality of infiltrating T cells, we analyzed the T-cell receptor beta (TCRβ) chains in colonic biopsies of MC, ulcerative colitis (UC), and their remission counterparts (CC/LC-HR [histological remission] or UC-R [remission]) compared with patients with noninflamed colons using next-generation sequencing. Compared with controls and patients with CC, patients with LC had significantly lower diversity with significantly lower evenness and richness in TCRVβ-Jβ gene segments. Similarly, patients with LC-HR had lower diversity because of significantly lower TCRVβ-Jβ clone richness. Patients with UC and UC-R showed significantly higher diversity and richness. Univariate and multivariate analyses were performed to identify TCRVβ-Jβ gene segments differentiating disease types from controls or their remission counterparts. Patients with LC were discriminated from controls by 12 clones and from patients with CC by 8 clones. Neither univariate nor multivariate analyses showed significance for patients with CC or CC-HR compared with controls. Patients with UC and UC-R had 16 and 14 discriminating clones, respectively, compared with controls. Altogether, patients with MC and UC showed an oligoclonal TCRβ distribution. TCRVβ-Jβ clone types and their diversity were distinctive between patients with CC and LC, as well as for patients with UC, suggesting different pathophysiological mechanisms according to disease type and stage. This study suggests that CC and LC are different entities because of differences in immunoregulatory responses, as mirrored by their T-cell repertoire.

    The inner mucus layer in mouse colon normally separates bacteria from the epithelium. Do humans have a similar inner mucus layer and are defects in this mucus layer a common denominator for spontaneous colitis in mice models and ulcerative colitis (UC)? The colon mucus layer from mice deficient in Muc2 mucin, Core 1 O-glycans, Tlr5, interleukin 10 (IL-10) and Slc9a3 (Nhe3) together with that from dextran sodium sulfate-treated mice was immunostained for Muc2, and bacterial localisation in the mucus was analysed. All murine colitis models revealed bacteria in contact with the epithelium. Additional analysis of the less inflamed IL-10(-/-) mice revealed a thicker mucus layer than wild-type, but the properties were different, as the inner mucus layer could be penetrated both by bacteria in vivo and by fluorescent beads the size of bacteria ex vivo. Clear separation between bacteria or fluorescent beads and the epithelium mediated by the inner mucus layer was also evident in normal human sigmoid colon biopsy samples. In contrast, mucus on colon biopsy specimens from patients with UC with acute inflammation was highly penetrable. Most patients with UC in remission had an impenetrable mucus layer similar to that of controls. Normal human sigmoid colon has an inner mucus layer that is impenetrable to bacteria. The colon mucus in animal models that spontaneously develop colitis and in patients with active UC allows bacteria to penetrate and reach the epithelium. Thus colon mucus properties can be modulated, and this suggests a novel model of UC pathophysiology.

    It is unknown why patients with extensive ulcerative colitis (UC) have a higher risk of colorectal cancer compared with patients with left-sided UC. This study characterizes the inflammatory processes in left-sided UC, pancolitis, and UC-associated dysplasia at the transcriptional level to identify potential biomarkers and transcripts of importance for the carcinogenic behavior of chronic inflammation. The Affymetrix GeneChip Human Genome U133 Plus 2.0 was applied on colonic biopsies from UC patients with left-sided UC, pancolitis, dysplasia, and controls. Reverse transcription polymerase chain reaction and immunohistochemistry were performed for validating selected transcripts in the initial cohort and in 2 independent cohorts of patients with UC. Microarray data were analyzed by principal component analysis, and reverse transcription polymerase chain reaction and immunohistochemistry data by the Wilcoxon's rank-sum test. The principal component analysis results revealed separate clusters for left-sided UC, pancolitis, dysplasia, and controls. Close clustering of dysplastic and pancolitic samples indicated similarities in gene expression. Indeed, 101 and 656 parallel upregulated and downregulated transcripts, respectively, were identified in specimens from dysplasia and pancolitis. Validation of selected transcripts hereof identified insulin receptor alpha (INSRA) and MAP kinase interacting serine/threonine kinase 2 (MKNK2) with an enhanced expression in dysplasia compared with left-sided UC and controls, whereas laminin γ2 (LAMC2) was found with a lower expression in dysplasia compared with the remaining 3 groups. This study demonstrates pancolitis and left-sided UC as distinct inflammatory processes at the transcriptional level, and identifies INSRA, MKNK2, and LAMC2 as potential critical transcripts in the inflammation-driven preneoplastic process of UC.

    To review the outcomes of metastatic melanoma patients treated with infliximab for severe steroid-refractory colitis secondary to ipilimumab therapy. Immune-related colitis is a known potential adverse effect of ipilimumab, that causes significant morbidity and extended hospital stays. There are limited outcome data for patients treated with infliximab for ipilimumab-induced colitis refractory to corticosteroids. Management guidelines have been developed based on case study evidence only. A retrospective review of all patients administered infliximab for ipilimumab-induced colitis at South Australian public hospitals between October 2011 and April 2015. Resolution of colitis/diarrhea, duration of hospital stay, dosage regimen of infliximab used (single dose vs multiple dose) and surgical intervention if required. Between October 2011 and April 2015, 106 patients were dispensed ipilimumab from South Australian public hospitals for the treatment of metastatic melanoma. Thirteen were administered infliximab for severe, steroid-refractory colitis secondary to ipilimumab. Sixty-two percent received a single dose of infliximab only. Four patients achieved resolution of colitis symptoms at 1 month postinfliximab. Thirty-three percent required surgical intervention despite treatment with infliximab. One patient declined surgery and subsequently died due to bowel perforation. The average number of overnight bed days due to colitis was 27. This series of patients with severe ipilimumab-induced colitis suggests that despite treatment with infliximab a high proportion of patients do not achieve resolution of symptoms. Review of these cases has highlighted the absence of evidence-based guidelines to treat severe, steroid refractory colitis secondary to ipilimumab. Further prospective studies may clarify the role of infliximab for the treatment of ipilimumab-induced colitis. © 2016 John Wiley & Sons Australia, Ltd.

    The aim of this analysis was to compare the advantages of the anal fistula plug (AFP) with the mucosa advancement flap (MAF) for complex anal fistulas. Comparative studies of the efficacy of AFP and MAF were included. Two independent reviewers selected articles for inclusion. After information collection, a meta-analysis was performed using data on overall healing rates, complications, incontinences and recurrences. The quality of postoperative life and cost were also included with the clinical results. Ten studies included 778 patients who were divided into AFP and MAF groups in this meta-analysis. During the follow-up period, no significant difference in healing rates, complications and recurrences were found (P = 0.55, P = 0.78 and P = 0.23, respectively). The incontinence rate of AFP was lower than that of MAF (P = 0.04). The postoperative quality of life of AFP patients was superior to that of MAF patients. The AFP patients had less persistent pain of a shorter duration and shortened healing time and hospital stay. The treatment cost of AFP patient was lower than that of MAF. Compared to the MAF procedure, the AFP procedure has some advantages for complex anal fistulas, but more and large randomized clinical trials comparing the two procedures for fistula management need to be conducted. © 2016 Royal Australasian College of Surgeons.

    Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy. Biopsy of both tumors revealed a similar histology of well- to moderately differentiated adenocarcinoma. There was no sign of metastases in lymph nodes or other organs. For the purpose of diagnosis and treatment, transperineal local resection of the anal tumor was performed, and it was histologically identified as adenocarcinoma of squamous cells with no invasion to muscles, lymph ducts, or microvessels. The pathological margin was free. Then, to achieve radical cure, laparoscopic low anterior resection (LAR) with D3 lymphadenectomy was performed. The histological diagnosis of the anal tumor was adenocarcinoma of squamous cells without invasion to muscles, lymph ducts, or vessels. The surgical margin was completely free. Immunohistochemical analysis of both tumors revealed similar staining patterns, and the final diagnosis was rectal cancer with metastasis to the anal skin. The patient received no postoperative therapy, and no recurrences have been observed 12 months after surgery. We expect that our sphincter-preserving surgical strategy provided a good prognosis for the synchronous rectal cancer and anal metastasis. This is a rare report of a case with an anal metastasis of colorectal cancer on perianal squamous cells without a history of anal disease that was resected while preserving anal function.

Conclusões: A infecção cervical por HPV é um fator sugestivo de risco para o desenvolvimento da infecção na região anal.

  15. Modelo analítico del efecto de PRS sobre satélites GPS

    Meza, A.; Brunini, C.; Usandivaras, J. C.

    El sistema GPS (Global Position System) es, hoy en día, la herramienta de navegación y posicionamiento más potente y lo será sin duda en la próxima década. Gran parte de su valiosa utilidad se debe a la alta precisión que permite lograr y ésta, a su vez, depende, entre otras causas, de la precisión con que se conocen las órbitas de los satélites. La presión de radiación solar (PRS) fija el límite de la precisión con que pueden calcularse en la actualidad las efemérides satelitarias. El objetivo de este trabajo es proponer una mejor resolución de este fenómeno. El modelo analítico aquí presentado, se basa en el análisis del comportamiento de los residuos de un ajuste por mínimos cuadrados en el que se utiliza el modelo de PRS propuesto por Beutler. El mismo consiste en un modelo determinista del fenómeno con dos parámetros libres. Los resultados obtenidos ponen de manifiesto que, aún después de aplicar dichos parámetros, prevalecen en los residuos efectos semidiurnos en las componentes radial,tangencial y normal. Estos resultados obtenidos se comparan con los de un trabajo desarrollado por el Instituto de Berne (Beutler et al., 1994), en el que se utilizaron como pseudo-observaciones las órbitas precisas del IGS (CODE). El intervalo de integración escogido por este centro fueron las semanas 680 y 681. En resumen se tienen arcos de 14 días para todos los satélites, donde las efemérides precisas de los mismos para los 14 días fueron utilizados como pseudo-observaciones. El modelo de fuerza que empleó dicho centro fue básicamente el tradicional en lo que respecta al modelo de las fuerzas gravitacionales, y para la PRS utilizo el modelo standard de Beutler. Los parámetros de este modelo junto con las 6 condiciones iniciales (posición y velocidad) fueron ajustados por el método general de mínimos cuadrados. Los residuos en la componente radial, tangencial y normal, para los satélites con un buen comportamiento, presentan una

    Full Text Available The European population is only suboptimally supplied with the essential trace element selenium. Such a selenium status is supposed to worsen colitis while colitis-suppressive effects were observed with adequate or supplemented amounts of both organic selenomethionine (SeMet and inorganic sodium selenite. In order to better understand the effect of these selenocompounds on colitis development we examined colonic phenotypes of mice fed supplemented diets before the onset of colitis or during the acute phase. Colitis was induced by treating mice with 1% dextran sulfate sodium (DSS for seven days. The selenium-enriched diets were either provided directly after weaning (long-term or were given to mice with a suboptimal selenium status after DSS withdrawal (short-term. While long-term selenium supplementation had no effect on colitis development, short-term selenite supplementation, however, resulted in a more severe colitis. Colonic selenoprotein expression was maximized in all selenium-supplemented groups independent of the selenocompound or intervention time. This indicates that the short-term selenite effect appears to be independent from colonic selenoprotein expression. In conclusion, a selenite supplementation during acute colitis has no health benefits but may even aggravate the course of disease.

  4. HPV infection and intraepithelial lesions from the anal region: how to diagnose?

    Directory of Open Access Journals (Sweden)

    Newton Sérgio de Carvalho

    Full Text Available In the last years, the prevalence of HPV infection in the anal region has increased, especially in some groups like homosexual and HIV-positive people. Since this infection can be associated with the development of squamous anal cancer due to its progression from HPV infection to anal intraepithelial neoplasia (AIN and finally to cancer, the screening and evaluation of these conditions are important. Anal cytology and high resolution anoscopy are good methods that are available and can be used. Although useful, these methods should be performed correctly and not indiscriminately in all patients. Patients for whom anal cytology screening is recommended are: HIV-infected patients, homosexuals, women who present with high-grade vulvar squamous intraepithelial neoplasia, vulvar cancer or cervical cancer. An abnormal anal cytology should be further evaluated with high resolution anoscopy.

    2016-02-01

    This study examines whether the anal fin undergoes secondary sexual development similar to other reproductive traits in salmonids. This hypothesis was tested by comparing the anal-fin size of female kokanee salmon Oncorhynchus nerka that were in the early and late stages of sexual development. Females in an advanced stage of maturation had significantly larger anal fins relative to females in an early state of maturation (+4-7%), indicating that the anal fin undergoes secondary sexual development. The magnitude of this secondary growth was comparable with snout length (+9-10%), which is known to undergo secondary sexual development in female salmonids. When morphological trait dimensions were compared between the sexes, the anal fin was the only morphological trait found to have a female-biased sexual size dimorphism. This is the first study to show that the anal fin of female salmonids undergoes secondary sexual development. © 2015 The Fisheries Society of the British Isles.

  6. Recent Advances in the Pharmacotherapy of Chronic Anal Fissure: An Update

    2008-07-01

    Full Text Available Surgical sphincterotomy reduces anal tone and sphincter spasm and promotes ulcer healing. Because the surgery is associated with the side effect of faecal incontinence, pharmacological agents to treat chronic anal fissure have been explored recently. Glyceryl trinitrate (GTN ointment (0.2% has an efficacy of up to 68% in healing chronic anal fissure, but it is associated with headache as the major and most common side effect. Though botulinum toxin injected into the anal sphincter healed over 80% of chronic anal fis-sures, it is more invasive and expensive than GTN therapy. Diltiazem ointment achieved healing of chronic anal fissure comparable to 0.2% GTN ointment but was associated with fewer side effects. Other drugs that have been tried are lidocaine, the alpha-adrenergic antagonist indoramin, and the potassium channel opener minoxidil.

    Ulcerative colitis is a chronic inflammatory disease of the rectum and colon. Although the pathogenesis of ulcerative colitis is not fully elucidated, cell-mediated immunity plays an important role in disease pathogenesis. Leukocytapheresis is a newly emerging therapy to eliminate activated leukocyte from systemic circulation. We have studied the effects of leukocytapheresis on patients with ulcerative colitis who had failed to respond to conventional therapy. A total of 51 patients with ulcerative colitis were treated with apheresis using a non-woven polyester fiber filter (Finecell, Asahi Medical Co.,Tokyo, Japan) originally developed as a microcoagulation elimination filter for massive transfusion. Of the 51 patients, 33 (64.7%) achieved clinical remission manifested by clinical activity and colonoscopic findings without any adverse effects. This result suggested that leukocytapheresis using Finecell might serve as an alternative therapy for ulcerative colitis as other leukocytapheresis using centrifugation or column.

  8. Relationship between Mast Cells and the Colitis with Relapse Induced by Trinitrobenzesulphonic Acid in Wistar Rats

    Directory of Open Access Journals (Sweden)

    Ana Carolina Luchini

    2009-01-01

    Full Text Available The present study aimed to clarify the role of mast cells in colitis with relapse induced in Wistar rats by trinitrobenzenosulphonic acid. Colitis induction increased the histamine concentration in the colon, which peaked on day 26. The number of mast cells, probably immature, was ten times higher on day 8. Different from animals infected with intestinal parasites, after colitis remission, mast cells do not migrate to the spleen, showing that mast cell proliferation presents different characteristics depending on the inflammation stimuli. Treatment with sulfasalazine, doxantrazole, quercetin, or nedocromil did not increase the histamine concentration or the mast cell number in the colon on day 26, thereby showing absence of degranulation of these cells. In conclusion, although mast cell proliferation is associated with colitis, these cells and their mediators appear to play no clear role in the colitis with relapses.

    2011-01-01

    Objective Anal sphincter complex consists of anatomically overlapping internal anal sphincter (IAS), external anal sphincter (EAS) & puborectalis muscle (PRM). We determined the functional morphology of anal sphincter muscles using high definition manometery (HDAM), 3D-ultrasound (US) and Magnetic resonance (MR) imaging. Patients We studied 15 nulliparous women. Interventions HDAM probe equipped with 256 pressure transducers was used to measure the anal canal pressures at rest and squeeze. Lengths of IAS, PRM and EAS were determined from the 3D-US images and superimposed on the HDAM plots. Movements of anorectal angle with squeeze were determined from the dynamic MR images. Results HDAM plots reveal that anal canal pressures are highly asymmetric in the axial and circumferential direction. Anal canal length determined by the 3D-US images is slightly smaller than measured by HDAM. The EAS (1.9 ± 0.5 cm long) and PRM (1.7 ± 0.4 cm long) surround distal and proximal parts of the anal canal respectively. With voluntary contraction, anal canal pressures increase in the proximal (PRM) and distal (EAS zone) parts of anal canal. Posterior peak pressure in the anal canal moves cranially in relationship to the anterior peak pressure, with squeeze. Similar to the movement of peak posterior pressure, MR images show cranial movement of anorectal angle with squeeze. Conclusion Our study proves that the PRM is responsible for the closure of the cranial part of anal canal. HDAM, in addition to measuring constrictor function can also record the elevator function of levator ani/pelvic floor muscles. PMID:21951657

    To study the results of stem-cell therapy under a Compassionate-use Program for patients with recurrent anal fistulae. Under controlled circumstances, and approved by European and Spanish laws, a Compassionate-use Program allows the use of stem-cell therapy for patients with very complex anal fistulae. Candidates had previously undergone multiple surgical interventions that had failed to resolve the fistulae, and presented symptomatic recurrence. The intervention consisted of limited surgery (with closure of the internal opening), followed by local implant of stem cells in the fistula-tract wall. Autologous expanded adipose-derived stem cells were the main cell type selected for implant. The first evaluation was performed on the 8(th) postoperative week; outcome was classified as response or partial response. Evaluation one year after the intervention confirmed if complete healing of the fistula was achieved. Ten patients (8 male) with highly recurrent and complex fistulae were treated (mean age: 49 years, range: 28-76 years). Seven cases were non-Crohn's fistulae, and three were Crohn's-associated fistulae. Previous surgical attempts ranged from 3 to 12. Two patients presented with preoperative incontinence (Wexner scores of 12 and 13 points). After the intervention, six patients showed clinical response on the 8(th) postoperative week, with a complete cessation of suppuration from the fistula. Three patients presented a partial response, with an evident decrease in suppuration. A year later, six patients (60%) remained healed, with complete reepithelization of the external opening. Postoperative Wexner Scores were 0 in six cases. The two patients with previous incontinence improved their scores from 12 to 8 points and from 13 to 5 points. No adverse reactions or complications related to stem-cell therapy were reported during the study period. Stem cells are safe and useful for treating anal fistulae. Healing can be achieved in severe cases, sparing fecal

    Over the years from 1992 to 1997, 41 anorectal malformations (ARM) with histopathologic alterations were investigated to determine which morphologic abnormalities of the distal rectum accompany ARMs. Three other cases showed normal neuromuscular morphology; 9 further cases could not be evaluated owing to scanty biopsies. All resected specimens were caudocranially coiled and cryostat cut at -20 degrees C into serial sections, which were stained with a lactic dehydrogenase, succinic dehydrogenase, nitroxide synthase, and acetylcholinesterase reaction as well as hemalum and sirius red. Ten low, 15 intermediate, and 10 high forms of anal atresia (AA) were studied. In addition, six cloacal abnormalities were investigated. In 7 cases (17%) (5 intermediate, 2 low AAs), the characteristics of Hirschsprung's disease were observed. Oligoneuronal hypoganglionosis of the myenteric plexus proximal to the anal floor was diagnosed in 7 AAs (12%). In 10 children with high-type AA and resection of 1-5 cm distal rectum and in all cloacal anomalies (n = 6) defects of the muscularis propria were seen in the rectal-atresia sac. These defects were characterized by hypoplasia of the circular-muscle layer and/or the internal anal sphincter (IAS). Intestinal neuronal dysplasia of the submucous plexus was most frequently observed (12%) in high-type AA. A correlation between innervation anomalies or anomalies of the muscularis propria and the type of fistula could not be seen. In conclusion, all cases with high-type AA and cloacal anomalies were characterized by anomalies of the muscularis propria and/or IAS but this was not the case in intermediate and low-type AAs. Anomalies of the enteric nervous system were diagnosed in 60% of AAs.

    Constantinou, Eugene C.; Daly, William; Fung, Claire Y.; Willett, Christopher G.; Kaufman, Donald S.; DeLaney, Thomas F.

    1997-01-01

    Purpose: To analyze the impact of patient and treatment parameters in concurrent chemoradiation treatment for anal carcinoma. Methods and Materials: Retrospective review of 50 MO anal cancer patients treated from 1984-1994. Most patients received concurrent 5-FU, mitomycin, and radiation. Local control and disease-free/overall survival were determined and analyzed according to patient and treatment parameters. Results: With 43 month median follow-up, projected overall survival is 66% at 5 and 8 years. Disease-free survival is 67% at 5 years and 59% at 8 years. Local control is 70% at 5 and 8 years. Doses of ≥54 Gy are associated with improved 5-year survival (84 vs. 47%, p = 0.02), disease-free survival (74 v. 56%, p = 0.09), and local control (77 vs. 61%, p = 0.04). Although local control, disease-free survival, and overall survival were improved in patients whose overall treatment time was <40 days, this was not statistically significant. Outcome in the four patients with pretreatment hemoglobin (Hgb) <10 appeared worse with 3-year overall survival 50 vs. 68% (p = 0.07), disease-free survival 0 vs. 67% (p = 0.11), and local control 0 vs. 74% (p = 0.05). Projected 5-year overall survival, relapse-free survival, and local control in 4 HIV (+) patients is 0, 75, and 75%. Multivariate analysis reveals that dose (p 0.02) and Hgb (p = 0.05) independently affect local control, dose (p = 0.02) affects disease-free survival, and dose (p = 0.01), Hgb (p = 0.03), T-stage (p = 0.03), and HIV-status (0.07) independently influence overall survival. Conclusion: Radiation doses of ≥54 Gy are associated with significantly improved survival and local control in anal cancer patients treated with chemoradiation. Overall treatment times of less than 40 days are associated with a trend towards improved outcome, but this is not significant. Pretreatment hemoglobin <10 is associated with worse treatment outcome. Survival of HIV (+) patient is poor, but the majority of such patients

    To review the outcome after restorative proctocolectomy among children and adolescents with ulcerative colitis at a pediatric inflammatory bowel disease center. The records of all patients with ulcerative colitis undergoing colectomy and ileoanal anastomosis at The Hospital for Sick Children, Toronto, Canada, were reviewed. Questionnaires concerning functional results were sent to patients with restored transanal defecation. Seventy three patients (mean age, 13.2 years; range, 2.6-18.8 years) underwent ileoanal anastomosis (19 straight ileoanal anastomosis, 41 J pouch, 13 S pouch) between January 1980 and June 1995 and were observed 5.8+/-3.3 years. The ileoanal anastomosis is nonfunctional in 19 (26%) patients. Excision rates according to type of restorative procedure were J pouch, 7% (3 of 41); S pouch, 32% (4 of 13); and straight ileoanal anastomosis, 32% (6 of 19). Failure was usually attributable to intractable diarrhea among patients with straight ileoanal anastomosis but was caused by anastomotic leak or pelvic-perianal sepsis among patients with pouch procedures. Failure rates did not vary with age at ileoanal anastomosis. Among patients retaining ileoanal continuity, continence problems reported in the questionnaire were frequent and tended to be more extreme among younger patients. Overall, 90% of respondents reported satisfaction with the functional outcome of the restorative operation. The success rate of the ileoanal anastomosis/J-pouch procedure is comparable to that in adult series. The ileoanal anastomosis/J-pouch procedure is the operation of choice for children and adolescents who want ileoanal continuity restored after colectomy for ulcerative colitis.

    Epidemiological and clinical data indicate that patients suffering from IBD with long-standing colitis display a higher risk to develop colorectal high-grade dysplasia. Whereas carcinoma invasion and metastasis rely on basement membrane (BM) disruption, experimental evidence is lacking regarding the potential contribution of epithelial cell/BM anchorage on inflammation onset and subsequent neoplastic transformation of inflammatory lesions. Herein, we analyse the role of the α6β4 integrin receptor found in hemidesmosomes that attach intestinal epithelial cells (IECs) to the laminin-containing BM. We developed new mouse models inducing IEC-specific ablation of α6 integrin either during development (α6 ΔIEC ) or in adults (α6 ΔIEC-TAM ). Strikingly, all α6 ΔIEC mutant mice spontaneously developed long-standing colitis, which degenerated overtime into infiltrating adenocarcinoma. The sequence of events leading to disease onset entails hemidesmosome disruption, BM detachment, IL-18 overproduction by IECs, hyperplasia and enhanced intestinal permeability. Likewise, IEC-specific ablation of α6 integrin induced in adult mice (α6 ΔIEC-TAM ) resulted in fully penetrant colitis and tumour progression. Whereas broad-spectrum antibiotic treatment lowered tissue pathology and IL-1β secretion from infiltrating myeloid cells, it failed to reduce Th1 and Th17 response. Interestingly, while the initial intestinal inflammation occurred independently of the adaptive immune system, tumourigenesis required B and T lymphocyte activation. We provide for the first time evidence that loss of IECs/BM interactions triggered by hemidesmosome disruption initiates the development of inflammatory lesions that progress into high-grade dysplasia and carcinoma. Colorectal neoplasia in our mouse models resemble that seen in patients with IBD, making them highly attractive for discovering more efficient therapies.

    Chronic anal fissures represent 15% of proctologic consultations, although their aetiopathogenesis is unclear and multifactorial. This study aims to identify the aetiopathogenesis, risk factor of recurrence after lateral subcutaneous internal anal sphincterotomy and existing correlation with sexual abuse, as sexual abuse accounts for over 21% of anal fissures. We retrospectively studied 80 cases of surgical (n = 54) and medical (n = 26) patients known with chronic anal fissure over eight months. We built an original questionnaire referring to the NorVold Abuse Questionnaire. Sixty cases were interviewed with only twenty filling the questionnaire themselves. Among the aetiological factors observed, as reported by these patients, we underlined chronic constipation 51 (64%), postoperative haemorrhoidectomy 15 (19%), sexual abuse 15 (19%), vaginal delivery and hysterectomy 10 (13%), traumatic anal sex 10 (13%), digital anal examination 4 (5%), anti-inflammatory non-steroid suppository 3 (4%), asthma with chronic cough 3 (4%). The recurrence rate reached 39% (31 cases, 13/26 (50%) in the medical group, against 18/54 (33%) in the surgical group. The 4/15 (27%) of sexual abuse happened in adulthood and 6/15 (40%) never disclosed this information. Sexual abuse is a significant aetiological factor of chronic anal fissures and it is to be suspected in cases of recurrence after anal sphincterotomy. For such cases, a multidisciplinary treatment is crucial to improve the prognosis of the disease. We recognise that the causality is difficult to prove and we cannot confirm that every sexually abused person could inevitably develop chronic anal fissure.

    Probiotic foods such as probiotic strain-fermented milk or supplements proposing various health claims are now available. The beneficial effects of these probiotic foods on the digestive system are expected for not only healthy persons but also patients with diseases of the alimentary tract. This review focused on the rationale of using our Bifidobacterium strains-fermented milk as an adjunct for the prevention of recurrence or exacerbation of colitis. Animal experiments using gnotobiotic colitis or spontaneously colitis models and also human clinical trials of ulcerative colitis patients showed the potential of Bifidobacterium strains-fermented milk as a beneficial anti-colitis adjunct.

    Chronic diarrhea is a very common problem in the general population. It requires a physician to differentiate its causes and depending on its etiology referring the patient to a hospital for diagnosis and subsequent treatment. One of the causes of chronic diarrhea may be microscopic colitis, which is characterized by the presence of clinical symptoms without endoscopic or radiological abnormalities. Diagnosis is based on a histopathological examination of the colon and thus clinical suspicion of the disease is so important for further diagnosis and treatment, which is primarily based on the use of topical steroids such as budesonide. © 2016 MEDPRESS.

    1982-01-01

    In a retrospective study of one hundred and seventy patients with ischaemic colitis, we found eight patients with partially obstructive carcinoma of the colon located distally, seven located in the sigmoid and one in the splenic flexure. The frequency of this association (1-4.7% in the literature and 5.3% in our series) requires careful examination by radiologist and surgeon. The radiologist should be alert to the association of ischaemic damage proximal to an obstructive colorectal cancer. The surgeon must examine any colonic segment removed for carcinoma in order to exclude an ischaemic process in the area of the anastomosis and prevent leakage at the anastomosis or stricture formation.

    Full Text Available ABSTRACTBackground: Coffee is one of the most widely consumed beverages in the world and it has been demonstrated that it has important therapeutic activities not only because of its caffeine content but also owing to the presence of other biologically active small molecules such as chlorogenic acid, trigonelline and cyclopentadiones. However, chlorogenic acid is degraded into catechol, pyrogallol and hydroxyhydroquinone, which are thought to induce irritation of the gastric mucosa. To reduce the content of irritant compounds processing methods have been developed prior to roasting the coffee beans.Objectives: The aim of this study was to study the anti-inflammatory and gastro-protective effects of processed coffee (Idee-Kaffee on in LPS-treated human primary monocytes and in a murine model of colon inflammation (IBD model.Results: In this study we have analyzed the effects on inflammatory events in cultured cells and in mice drinking a commercially available processed coffee. The processed coffee inhibited lipopolysaccharide (LPS-induced proinflammatory cytokines such as interleukin (IL-1, tumor necrosis factor (TNF, IL-6 and IL-8, and other inflammatory mediators such as prostaglandin (PGE2 and 8-isoprostane in cultured human primary monocytes. Oral administration of dissolved processed coffee, i.e., in its usual beverage form, improved greatly the adverse macroscopic and histological features of dextran sodium sulfate (DSS-induced colitis in mice in a dose-dependent manner. Processed coffee not only largely prevented DSS-induced colitis but also dramatically suppressed in vivo NF-B and STAT3 activities through inhibition of IB and STAT3 phosphorylation. Furthermore, this solubleFunctional Foods in Health and Disease 2013; 3(5:133-145coffee bean extract reduced the expression of proinflammatory cytokines TNF, IL-11, and IL-6 and the expression of cyclooxygenase (COX-2 in colonic tissues.Conclusions: This work identified

    OBJECTIVE: Epithelial apoptosis rates are increased in ulcerative colitis (UC). The increased apoptosis rate could expose mucosal cells to luminal pathogens and thereby be regarded as a primary pathogenic factor in UC. On the other hand, the local inflammatory reaction could cause epithelial...... apoptosis secondary to the release of cytotoxic mediators. If apoptosis is a primary defect, apoptosis rates could influence the degree of spreading of inflammation and the clinical course of UC. If apoptosis is a side effect of local inflammation, apoptosis rates would be expected only to correlate...

    Full Text Available A 25-year-old male with a background of ulcerative colitis presented with a two-week history of central chest pain. His ECG on presentation showed global T wave inversion with a peak troponin I of 165 ng/mL. Clinical diagnosis of myopericarditis/myocarditis was made. Echocardiography and cardiac magnetic resonance (MR confirmed the diagnosis. On detailed assessment of his medication history, mesalazine was suspected as an etiological factor, with discontinuation resulting in an improvement in symptoms, inflammatory markers and cardiac enzymes. This is a unique case of mesalazine-induced myopericarditis on a background of inflammatory bowel disease.

    Full Text Available Background. As to severity of the course, the incidence of complications and mortality rate, ulcerative colitis hold a position within the top of the gastrointestinal system diseases in children. Goal of research — to study peculiarities of the course of ulcerative colitis at the present stage. Materials and methods. The retrospective analysis was conducted of 184 clinical records of the children, who were on examination and treatment at the Department of the diseases of gastrointestinal system of the State Institution “Institute of Pediatrics, Obstetrics and Gynecology of the National Academy of Medical Sciences of Ukraine” between 2004 and 2014. Results and discussion. Ulcerative colitis is common in the children of all ages, among which the preschool children and teenagers are at greater risk than others. The risk factors include both the antenatal and the postnatal ones: gestational toxicosis and miscarriage threat, weight deficit at birth, artificial feeding, intestinal infections. Ulcerative colitis is characterized by chronic relapse, slow progression of the disease, and the typical clinical symptoms are: diarrhea, hemorrhagic colitis, abdominal pain syndrome, toxic syndrome, late physical development. In terms of localization, the inflammation process most often affects the entire large bowel (59.6 %, left-sided colitis (28.5 %, and proctosigmoiditis (accounts for 11.9 % are less common. The informative criteria of ulcerative colitis activity are the Pediatric Ulcerative Colitis Activity Index (PUCAI, fecal calprotectin level, a number of complete blood count values (hemoglobin, leucocytes, platelets, erythrocyte sedimentation rate and biochemical studies (C-reactive protein, alpha-2 globulins. The modern combined baseline therapy is efficient in 22 % of patients suffering from total colitis, in 42–58 % — from left-sided colitis according to the follow-up study results. Monotherapy with 5-aminosalicylic acid medications was

    After sphincter-sparing core fistulectomy for deep anal fistula most surgeons advance a rectal mucosal flap to reinforce closure of the internal opening. Our own method having for many years been simple appositional closure the resulting series presented an opportunity for comparison. From November 1987 to January 2001, 44 patients underwent 46 core fistulectomies with flap-less direct appositional closure in our unit. Records were kept prospectively. Twenty-six fistulae (in 28 patients) appeared healed at two to five months follow-up and the patients had been discharged. A full review was mounted in May 2001, when 16 of the healed patients could be contacted and questionnaires completed. Two patients were excluded from the study. The procedure failed in 16 patients initially and was found to have done so in two more at long-term follow-up (41% overall). Three patients had died and five could not be traced. Simple appositional closure after core fistulectomy for deep anal fistula seems inferior to methods using flap reinforcement.

    Anal canal carcinoma are highly curable by irradiation, combined with chemotherapy in locally advanced disease, with preservation of sphincter function. The clinical target volume for the nodes is extended, often including the inguinal nodes, which is not usual for other pelvic tumours. Acute and late effects are correlated with the volume and dose delivered to organs at risk, i. e. small bowel, bladder and increased by concomitant chemotherapy. Intensity modulated irradiation (IMRT) makes it possible to optimize the dose distribution in this 'complex U shaped' volume, while maintaining the dose distribution for the target volumes. The conversion from conformal irradiation to IMRT necessitates good knowledge of the definition and skills to delineate target volumes and organs at risk, including new volumes needed to optimize the dose distribution. Dosimetric and clinical benefits of IMRT are described, based on early descriptions and evidence-based publication. The growing development of IMRT in anal canal radiotherapy must be encouraged, and long-term benefits should be soon published. Radiation oncologists should precisely learn IMRT recommendations before starting the technique, and evaluate its early and late results for adverse effects, but also for long-term tumour control.

    Full Text Available Lactobacillus rhamnosus GG was assessed for its ability to alleviate DSS-induced colitis in mice and activate epidermal growth factor receptor and Akt signaling in intestinal epithelial cells. In this study mice were treated with DSS to induce colitis and they were given Lactobacillus GG fermented milk to assess the effect of probiotic on colitis. Lactobacillus GG fermented milk significantly reduced the colitis associated changes suggesting a protective effect against DSS induced colitis.

    Es un estudio investigativo de tipo cualitativo, dentro del enfoque hermenéutico, en donde se busca conocer el significado que los padres asignan a las malformaciones anorectales o enfermedad de Hirschprung y el tratamiento en sus hijos, incluyendo las dilataciones anales; con el propósito de encontrar aproximaciones a sus sentidos y construir estrategias de atención que beneficien el estado físico del niño y apunten a un mayor equilibrio psicosocial de los padres. Es por ello, que las categorías de análisis están insertas en la actitud, entendida ésta como la síntesis de lo afectivo, lo cognitivo y lo práxico. Mediante la historia clínica hospitalaria, se seleccionaron a los padres a quienes se les hizo la entrevista y se les observó la actitud frente a las malformaciones y su tratamiento en más de una ocasión, obteniéndose la información que condujo a las conclusiones. Se entrevistaron y observaron 25 padres de familia y sus respectivos hijos, no sin antes señalar que se trató de recoger una experiencia de 4 años atrás, con otros padres con similar problemática.

    Full Text Available Este texto plantea la relevancia de abordar la modernidad como objeto etnográfico, esto es, examinarla desde discursos y prácticas situadas. Esta etnografía se inspira en un enfoque foucaultiano donde la gubernamentalidad es una categoría clave. Desde esta perspectiva, se propone un abordaje que examine tres dimensiones analíticas de la modernidad. En primera instancia están las razones de gobierno; esta dimensión reúne todas aquellas formas de conocimiento, de experticia y de cálculo que hacen posible que pensemos a los seres humanos como susceptibles de programación política. En segundo lugar están las técnicas de gobierno; al ámbito de lo técnico pertenecen los mecanismos prácticos, los instrumentos y los programas por medio de los cuales autoridades de distintos tipos buscan dar forma e instrumentalizar la conducta humana. Finalmente están los sujetos de gobierno; esta dimensión cubre los diversos tipos de identidad individual y colectiva que emergen a partir de, y al mismo tiempo sustentan, la actividad gubernamental.

    It is well-known that inflammatory bowel disease (IBD) poses an increased, yet not definitely estimated, risk of colitis-associated colon cancer (CAC), which is considered a more aggressive and distinct in both genetic and molecular levels clinical entity compared to sporadic colorectal cancer (CRC). The present review discusses the cytokine networks involved in CAC-based translational findings from suitable animal models of the disease. Moreover, we summarize the most prominent data concerning the role of Th1, Th2, Th17 and anti-inflammatory cytokines in the pathogenesis of CAC. Last, we briefly address the controversies between basic science findings in IBD and CAC and suggest further directions regarding research on cytokines. This review should serve as a primer for clinicians and surgeons to understand the rapidly evolving field of cytokines in the context of CAC. The MEDLINE database was thoroughly searched using the keywords: cytokines, colitis-associated cancer, animal models, carcinogenesis. Additional articles were gathered and evaluated.

Corticosteroids (CSs were the first drugs used in the management of UC and are still used for induction of remission. However, because of their extensive side-effect profile, they are not utilized for maintenance of remission. In view of this, CS-free remission has become an important end point while evaluating therapeutic agents used in the management of UC. This review highlights the results of various studies conducted to evaluate the efficacy of different medications to attain CS-free remission in the setting of active UC. The drugs reviewed include established agents such as thiopurines, methotrexate, infliximab, adalimumab, vedolizumab, golimumab, and newer experimental agents, and if all else fails, colectomy will be performed. The efficacy of these drugs is evaluated individually. Our aim is to provide a synopsis of the work done in this field to date.

    5-Aminosalicylate (5-ASA) is widely used as the first-line drug for ulcerative colitis (UC). 5-ASA is mostly a safe and effective drug, but it can bring about exacerbation due to 5-ASA intolerance. 5-ASA intolerance can be confusing and it can mislead physicians into considering unnecessary treatment escalation, including corticosteroid (CS), biologics, or even surgery. In spite of the clinical importance of 5-ASA intolerance, there have been few studies on its incidence, clinical features, and diagnosis. In order to evaluate the incidence, characteristic symptoms, disease course, and laboratory data of children with 5-ASA intolerance, we retrospectively reviewed the medical records of 80 children with UC. Eleven of 80 children (13.8%) with UC were diagnosed with 5-ASA intolerance. The median time between the initiation of 5-ASA and the onset of 5-ASA intolerance was 10 days (range, 4-20 days) in patients not receiving CS. Drug-induced lymphocyte stimulation test (DLST) was performed in 10 patients, and was positive in eight. C-reactive protein (CRP) increased significantly when exacerbation of colitis symptoms occurred. The incidence of 5-ASA intolerance was relatively high. Besides the challenge test, elevation of CRP and positive DLST appeared to support the diagnosis of 5-ASA intolerance. © 2017 Japan Pediatric Society.

    Full Text Available Eosinophilic colitis is a rare form of primary eosinophilic gastrointestinal disease that is poorly understood. Neonates and young adults are more frequently affected. Clinical presentation is highly variable depending on the depth of inflammatory response (mucosal, transmural, or serosal. The pathophysiology of eosinophilic colitis is unclear but is suspected to be related to a hypersensitivity reaction given its correlation with other atopic disorders and clinical response to corticosteroid therapy. Diagnosis is that of exclusion and differential diagnoses are many because colonic tissue eosinophilia may occur with other colitides (parasitic, drug-induced, inflammatory bowel disease, and various connective tissue disorders. Similar to other eosinophilic gastrointestinal disorders, steroid-based therapy and diet modification achieve very good and durable responses. In this paper, we present our experience with this rare pathology. Five patients (3 pediatric and 2 adults presented with diarrhea and hematochezia. Mean age at presentation was 26 years. Mean duration of symptoms before pathologic diagnosis was 8 months. Mean eosinophil count per patient was 31 per high-power field. The pediatric patients responded very well to dietary modifications, with no recurrences. The adult patients were treated with steroids and did not respond. Overall mean followup was 22 (range, 2–48 months.

    Wegener granulomatosis (WG) is an idiopathic small vessel vasculitis involving primarily airway and kidneys. Intestinal involvement of WG is rare and usually occurs after several years of WG and its treatment. We report a case of WG, presented initially as rapid-onset hemorrhagic pancolitis without any preexisting or concurrent illness or any medication use. A 79-year-old previously healthy woman presented with 2-day duration of bloody diarrhea. Colonoscopy showed pancolitis with numerous ulcers; the biopsy showed foci of inflammation, ulceration and hemorrhage in the lamina propria, without features of chronic inflammatory bowel disease. Her stool studies were negative for infection. She subsequently developed pulmonary hemorrhage and kidney dysfunction. Kidney biopsy showed pauci-immune necrotizing glomerulonephritis. She responded to a combination therapy of steroids, cyclophosphamide and plasmapheresis with resolution of intestinal and pulmonary symptoms and improvement of kidney function. This case represents the first known example of colitis as an initial presentation of WG without confounding etiologic factors. Hemorrhagic colitis, although uncommon, may be the major presenting feature of WG.
