    Introduction Proctocolectomy with ileal pouch-anal anastomosis (IPAA) was performed in ulcerative colitis (UC) for emergent or urgent indications in three stages. Since the three-step procedure imposes enormous demands on a patient, there was an attempt to introduce primary IPAA for urgent indications. The aim of this study was to compare early complications after Hartmann's colectomy (HC) and IPAA in a selected group of patients. Material and methods Medical records of 274 patients who under...

    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.

    Stem cell transplantation showed promising results in IBD management. However, the therapeutic impacts of cell delivery route that is critical for clinical translation are currently poorly understood. Here, three different MSCs delivery routes: intraperitoneal (IP), intravenous (IV), and anal injection (AI) were compared on DSS-induced colitic mice model. The overall therapeutic factors, MSCs migration and targeting as well as local immunomodulatory cytokines and FoxP3+ cells infiltration were analyzed. Colitis showed varying degrees of alleviation after three ways of MSCs transplantation, and the IP injection showed the highest survival rate of 87.5% and displayed the less weight loss and quick weight gain. The fecal occult blood test on the day 3 also showed nearly complete absence of occult blood in IP group. The fluorescence imaging disclosed higher intensity of engrafted cells in inflamed colon and the corresponding mesentery lymph nodes (MLNs) in IP and AI groups than the IV group. Real time-PCR and ELISA also demonstrate lower TNF-α and higher IL-10, TSG-6 levels in IP group. The immunohistochemistry indicated higher repair proliferation (Ki-67) and more FoxP3+ cells accumulation of IP group. IP showed better colitis recovery and might be the optimum MSCs delivery route for the treatment of DSS-induced colitis. PMID:27488951

    Full Text Available Uma solução analítica foi desenvolvida, para avaliar sulcos abertos e em declive, com base na teoria de Balanço de Volume de Walker e Skogerboe (1987. Essa metodologia é capaz de obter, matematicamente, a performance de um sistema, dispensando a construção de gráficos que definem os parâmetros de avaliação. A solução matemática é baseada no ajuste de equações ao modelo potencial, no cálculo das áreas sob as curvas definidas no ajuste e na intercessão de curvas, obtendo-se, assim, a performance de sistemas de irrigação por sulcos abertos e em declive. Para validação da metodologia, foi realizado um experimento de campo, na Fazenda Experimental da Universidade Federal do Ceará, situada no município de Pentecoste, pertencente ao Centro de Ciências Agrárias. Os dados de campo foram submetidos à análise pelas duas metodologias. Os resultados mostraram que a metodologia analítica pode ser usada para avaliar a irrigação por sulcos abertos e em declive.

    Full Text Available Microscopic colitis may be defined as a clinical syndrome, of unknown etiology, consisting of chronic watery diarrhea, with no alterations in the large bowel at the endoscopic and radiologic evaluation. Therefore, a definitive diagnosis is only possible by histological analysis. The epidemiological impact of this disease has become increasingly clear in the last years, with most data coming from Western countries. Microscopic colitis includes two histological subtypes [collagenous colitis (CC and lymphocytic colitis (LC] with no differences in clinical presentation and management. Collagenous colitis is characterized by a thickening of the subepithelial collagen layer that is absent in LC. The main feature of LC is an increase of the density of intra-epithelial lymphocytes in the surface epithelium. A number of pathogenetic theories have been proposed over the years, involving the role of luminal agents, autoimmunity, eosinophils, genetics (human leukocyte antigen, biliary acids, infections, alterations of pericryptal fibroblasts, and drug intake; drugs like ticlopidine, carbamazepine or ranitidine are especially associated with the development of LC, while CC is more frequently linked to cimetidine, non-steroidal antiinflammatory drugs and lansoprazole. Microscopic colitis typically presents as chronic or intermittent watery diarrhea, that may be accompanied by symptoms such as abdominal pain, weight loss and incontinence. Recent evidence has added new pharmacological options for the treatment of microscopic colitis: the role of steroidal therapy, especially oral budesonide, has gained relevance, as well as immunosuppressive agents such as azathioprine and 6-mercaptopurine. The use of anti-tumor necrosis factor-α agents, infliximab and adalimumab, constitutes a new, interesting tool for the treatment of microscopic colitis, but larger, adequately designed studies are needed to confirm existing data.

    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.

    Full Text Available SUMMARY Subtotal colectomy and ileostomy (SCI is now urgently used as the life-saving management of the severe, life - threatening, progressions in the course of ulcerative colitis (UC. PURPOSE. To evaluate the efficacy of SCI in patients with severe colitis, we reviewed our own experience in 12 patients with this condition. METHODS. Patients undergoing SCI included 6 males and 6 females aged 12 to 56 years (mean 35,8 years. The duration of the disease averaged 29 months (range 4 to 92 months. Three had had their disease less than 6 months. Eleven patients had total colitis and only one patient had left-sided colitis. Three patients endured a continuous course and in 9 the course was intermittent. All were anemic with protein concentration less than 5 gm/dl at the time of surgery. Five patients had fulminant colitis with severe hemorrhage and seven patients with pancolitis developed toxic megacolon with unrecognized perforation in one case preoperatively. All patients underwent an emergency SCI with either intrapelvic oversewing the rectum (7 patients or exteriorizing it as a mucus fistula (5 patients. One patient with toxic megacolon died in the first postoperative day because of uncontroled septic shock. The remainder 11 patients survived and later underwent rectectomy, anal mucosectomy and ileal pouch anal anastomosis (IPAA. CONCLUSION. SCI for patients with fulminant ulcerative colitis and toxic megacolon is a life-saving procedure which gives the chance for ileal pouch anal anastomosis (IPAA a second time.

    Eosinophilic colitis (EC) is a rare form of primary eosinophilic gastrointestinal disease with a bimodal peak of prevalence in neonates and young adults. EC remains a little understood condition in contrast to the increasingly recognized eosinophilic esophagitis. Clinical presentation of EC is highly variable according to mucosal, transmural, or serosal predominance of inflammation. EC has a broad differential diagnosis because colon tissue eosinophilia often occurs in parasitic infection, drug-induced allergic reactions,inflammatory bowel disease, and various connective tissue disorders, which require thorough searching for secondary causes that may be specifically treated with antibiotics or dietary and drug elimination.Like eosinophilic gastrointestinal disease involving other segments of the gastrointestinal tract, EC responds very well to steroids that may be spared by using antihistamines, leukotriene inhibitors and biologics.

    Microscopic colitis, which includes lymphocytic colitis and collagenous colitis, represents a frequent cause of chronic watery diarrhea especially in the elderly population. Several medications, such as nonsteroidal antiinflammatory drugs, proton pump inhibitors or antidepressants, as well as cigarette smoking have been recognized as risk factors for microscopic colitis. The diagnosis of microscopic colitis is based on a macroscopically normal ileo-colonoscopy and several biopsies from the entire colon, which demonstrate the pathognomonic histopathologic findings. Therapy is mainly based on the use of budesonide. Other medications, such as mesalazine, cholestyramine and bismuth, have been evaluated as well but the evidence is less solid. PMID:25276996

  8. Sulfate-reducing bacteria colonize pouches formed for ulcerative colitis but not for familial adenomatous polyposis.

    LENUS (Irish Health Repository)

    Duffy, M

    2012-02-03

    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

  10. Endosonographic and manometric assessment of the anal sphincters after ileal pouch-anal anastomosis

    International Nuclear Information System (INIS)

    Background. The aim of this study was to compare endosonography and manometry of the anal sphincters in patients after ileal pouch-anal anastomosis (IPAA). Patients and methods. Ten patients aged between 23 and 50 years with IPAA performed for ulcerative colitis were examined with anal endosonography (AES) and manometry. Results. AES visualised abnormal image of the internal anal sphincter (IAS) in 9 patients (90%). Defects of the external anal sphincter (EAS) and puborectalis muscle (PR) were shown in 4 patients (40%). In 5 patients (50%) correlation between endosonographic and manometric assessment for the all analysed muscles: IAS, EAS and PR was found. In 4 cases (40%) both methods correlated with the evaluation of the EAS only and in 1 patient (10%) no correlation was found. Correlation between both methods for the IAS was found in half of the patients (50%) while in the evaluation of the EAS and PR dynamic activity, it was found in 9 cases (90%). Conclusions. Anal endosonography and manometry allow us to assess the morphology as well as the function of the anal sphincters in patients with IPAA. The methods mentioned above show high correlation in the assessment of the EAS function (9 cases; 90%) whereas in the case of IAS, manometry frequently (5 patients; 50%) does not confirm endosonografically detected defects.

    Microscopic forms of colitis have been described, including collagenous colitis. This disorder generally has an apparently benign clinical course. However, a number of gastric and intestinal complications, possibly coincidental, may develop with collagenous colitis. Distinctive inflammatory disorders of the gastric mucosa have been described, including lymphocytic gastritis and collagenous gastritis. Celiac disease and collagenous sprue (or collagenous enteritis) may occur. Colonic ulceration has been associated with use of nonsteroidal anti-inflammatory drugs, while other forms of inflammatory bowel disease, including ulcerative colitis and Crohn's disease, may evolve from collagenous colitis. Submucosal "dissection", colonic fractures or mucosal tears and perforation from air insufflation during colonoscopy may occur and has been hypothesized to be due to compromise of the colonic wall from submucosal collagen deposition. Similar changes may result from increased intraluminal pressure during barium enema contrast studies. Finally, malignant disorders have also been reported, including carcinoma and lymphoproliferative disease.

    The ideal surgical treatment for ulcerative colitis is the ileoanal anastomosis (IAA), which, however, is not yet generally accepted as a practical procedure because of a suboptimal fecal function, frequent postoperative complications and technical difficulties. Based on one (U.) of the authors experiences on 36(34) polyposis and 19(12) colitis (paracentesis indicate the number of cases in (U.)'s previous appointment, Tokyo Medical and Dental University, 1977-1983). The practical procedure of IAA can be achieved by combining the following basic principles; a direct anastomosis of J-shape ileal pouch to the anal sphincteric mechanism, temporarily exclusion of the anastomosis by a loop-ileostomy, mucosectomy confined to the lower rectum leaving the short muscular cuff, and meticulous dissection of inflamed mucosa of the anal canal minimizing the damage to the internal sphincter which is achieved by the prone ano-abdominal approach. At elective operation, the procedure can be performed either as primary surgery or as the secondary following rectum preserving operation, in which, coeco-rectal anastomosis is advisable for preserving the ileocolic vessels that is helpful for J-pouch construction. In emergency surgical program, IAA is still be preserved as a final restructive surgery following colectomy with an open rectal exclusion or Turnbull' s total colonic exclusion. In this occasion, an ascendicostomy is advisable for preserving the ileocolic vessels. PMID:4088260

Estos modelos de líneas son transparentes, lo que impide ocultar las líneas que su sitúan en un segundo plano, y ocupan gran cantidad de memoria, lo que dificulta su manipulación informática. Para resolver ese problema es necesario descomponer el modelo 3D por archivos y capas de dibujo. Cada archivo de dibujo incluye las líneas restituidas de un elemento constructivo y se identifica por la tipología del elemento y su posición en el espacio del edificio. Las líneas se separan en capas según su orientación geográfica y su tipología (arista, contorno, fisura, etc..

    Three patients developed acute colitis, either de novo, or as an exacerbation of pre-existing colitis, following the use of oral acyclovir, prescribed for Herpes zoster or Herpes simplex infection. Rechallenge with oral acyclovir was performed in one patient, and resulted in a recurrence of colitic symptoms. It is speculated that acyclovir can have a direct irritant effect on large bowel mucosa. PMID:9146784

    Full Text Available Purpose: omega 3 polyunsaturated fatty acids have anti-inflammatory properties and can be beneficial in the treatment of inflammatory diseases, such as ulcerative colitis. Dextran sodium sulphate (DSS colitis in rats appears to mimic nearly all of the morphological characteristics and lesion distributions of ulcerative colitis. The purpose of the current study was to investigate the efficacy of omega 3 fatty acids in the treatment of experimental ulcerative colitis. Methods: thirty-six Wistar rats were randomly assigned to group A or group B receiving 5% dextran sulfate sodium (DSS in their drinking water for eight days. For the next eight days post-DSS, group A animals received tap-water, and group B animals were fed a nutritional solution containing high levels of omega 3 polyunsaturated fatty acids (ProSure®, Abbott Laboratories, Zwolle, Netherlands once per day, administrated with a orogastric feeding tube. Results: animals fed an omega 3 rich diet exhibited a statistically significant increase in hematocrit and hemoglobin levels, compared to animals drinking tap water, and a trend towards histopathological and clinical improvement, with the administration of omega 3 fatty acids ameliorating epithelial erosion by day 8 post-DSS, but no statistically significant difference was observed between group A and group B animals at 4 or 8 days post-DSS. Also, a statistically significant increase in neutrophil infiltration was observed, as depicted by myelohyperoxidase activity. Conclusion: our findings support a positive role of omega 3 polyunsaturated fatty acids supplementation in an experimental model of ulcerative colitis despite the increased colonic neutrophil infiltration. Further studies are needed in order to investigate the role of increased neutrophils in colonic mucosa.

    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.

    Full Text Available Ulcerative colitis (UC is a chronic idiopathic inflammatory disorder of colon. Frequency of UC is gradually increasing over few years worldwide. Prevalence is 35 to 100/100 000 people in USA, 1% of them are infants. UC develops in a genetically predisposed individual with altered intestinal immune response. An eight-month-old girl presented with loose bloody stool, growth failure, and moderate pallor. The girl was diagnosed as a case of UC by colonoscopy and biopsy. Treatment was thereafter started with immunosuppressive drugs. After initial induction therapy with parenteral steroid and infliximab, the patient is now on remission with azathioprine and mesalamine. UC is rare in Bangladesh, especially in children, and it is rarer during infancy. Several conditions like infective colitis, allergic colitis, Meckel′s diverticulitis, Crohn′s disease, etc. may mimic the features of UC. So, if a child presents with recurrent bloody diarrhea, UC should be considered as differential diagnosis.

    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.

    A 26-year-old woman with ulcerative colitis was transferred to our hospital with left hemiparesis due to cerebral infarction. Cervical ultrasonography and magnetic resonance imaging angiography revealed thrombosis at the right common carotid artery and the right internal carotid artery. Antithrombotic and anticoagulant therapies were commenced. After about 2 wk of the treatment, the frequency of her diarrhea increased. She underwent emergency subtotal colectomy, but 10 d later an abundant hemorrhage from the remnant rectum occurred, so the remnant rectum was resected and an ileal pouch anal anastomosis was performed. Antithrombotic and anticoagulant therapies were continued, but neither her neurological status nor magnetic resonance imaging angiography findings showed subsequent changes. She was discharged 3 mon after operation. This is a rare case of common carotid arterial thrombosis occurring as a complication of ulcerative colitis, in which antithrombotic and anticoagulant therapies are considered to provoke a deterioration of the patient's bowel disease.

Ocorre, geralmente, em pacientes cuja doença ativa é resistente ao tratamento clínico e, em algumas situações, o fator desencadeante é desconhecido. A infecção pelo cytomelogalovirus em seres humanos em geral é evento subclínico; entretanto, em pacientes imunocomprometidos a primoinfecção ou mesmo a reativação de infecção latente pode ter amplas repercussões clínicas, uma das quais o desencadeamento de megacólon tóxico. Objetivo - Descrever um caso de megacólon tóxico fatal por cytomegalovirose em paciente com retocolite ulcerativa idiopática. Paciente - Masculino, 38 anos, com clínica de diarréia e perda ponderal cuja investigação mostrou tratar-se de retocolite ulcerativa idiopática e para a qual foi instituída terapêutica imunossupressora vigorosa. Resultados - Evoluiu com quadro clínico de megacólon tóxico, sendo submetido a colectomia total. Complicações clínicas culminaram no óbito pós-operatório e o estudo anatomopatológico do cólon revelou doença ativa, associada a ulcerações confluentes na base das quais foram observadas células com alterações características da cytomegalovirose. Conclusão - A cytomegalovirose deve ser considerada como um dos agentes causadores de megacólon tóxico em retocolite ulcerativa.Background - The toxic megacolon is a rare and severe complication of ulcerative colitis.

    Full Text Available El cáncer anal solía ser una neoplasia infrecuente que afectaba principalmente a mujeres y personas mayores de 65 años, pero recientemente su incidencia ha venido en aumento debido a la pandemia de VIH, fenómeno que tiende a empeorar porque la terapia antirretroviral altamente activa (HAART, por su sigla en inglés no solo alarga la vida de los pacientes, sino que al mismo tiempo hace posible una prolongada evolución de las lesiones precancerosas que conducen a cáncer anal; además, está plenamente demostrado que la HAART no evita la evolución de las lesiones intraepiteliales escamosas hacia cáncer anal. La citología anal ha demostrado ser una prueba de tamización poblacional útil y costoefectiva para el diagnóstico de las lesiones precancerosas producidas por Papilomavirus humano en el canal anal de hombres homosexuales y bisexuales, principalmente de aquellos positivos para VIH. Esta revisión tiene como objetivo llamar la atención sobre la creciente incidencia de cáncer anal en la población de pacientes VIH positivos, y sobre la utilidad del diagnóstico temprano utilizando la citología anal en este grupo de pacientes de riesgo.

    Anal condyloma acuminatum is a human papillomavirus (HPV) that affects the mucosa and skin of the anorectum and genitalia. Anal condyloma acuminatum is the most commonly diagnosed sexually transmitted disease in the United States. To date, there are more than 100 HPV types, with HPV-6, HPV-10, and HPV-11 predominately found in the anogenital region and causing approximately 90% of genital warts. Risk factors for anal condyloma acuminatum include multiple sex partners, early coital age, anal intercourse, and immunosuppression. Transmission occurs by way of skin-to-skin contact through sexual intercourse, oral sex, anal sex, or other contact involving the genital area. The virus may remain latent for months to years until specific mechanisms cause production of viral DNA, leading to the presentation of anal condyloma acuminatum.Patients with anal condyloma acuminatum may be asymptomatic or present with presence of painless bumps, itching, and discharge or bleeding. It is not uncommon to have involvement of more than one area, and multiple lesions may also be present and extend into the anal canal or rectum. To date, there is no serologic testing or culture to detect anal condyloma acuminatum; therefore, diagnosis is made clinically or by detection of HPV DNA. Multiple factors determine the choice of treatment, which may range from patient-applied medications to surgical intervention. Despite treatment choice, recurrence rates are high, indicating the importance of patient education on prevention of HPV infection and reinfection. Unfortunately, at this time, no cure exists for anal condyloma acuminatum; however, recently Gardasil and Cervarix (in Australia only) vaccines have become available and are showing promising results.

    Cytokines orchestrate immune and inflammatory responses involved in the pathogenesis of ulcerative colitis (UC). Protein kinases are essential for signal transduction in eukaryotic cells. Janus kinases (JAKs) are a family of protein tyrosine kinases that play a pivotal role in cytokine receptor signaling. Indeed, a major subgroup of cytokines use Type I and II cytokine receptors which signal via the activation of JAKs. Tofacitinib is an oral JAK inhibitor that has been studied in autoimmune pathologies, including UC and rheumatoid arthritis with good overall efficacy and acceptable safety profile. This literature review was performed with the goal of summarizing the knowledge on JAK inhibitors in UC treatment. PMID:27140405

    Anal canal epidermoid carcinomas represent 1.2% of digestive cancers and 6% of ano-rectal cancers. For localized diseases, the treatment is based on radiotherapy with or without chemotherapy (5-FU and cisplatin or mitomycin), according to tumour and nodal extension. The recommended treatment dose is 45 Gy in the anal canal, the mesorectum, para-rectal lymph nodes, and inguinal lymph nodes. An additional dose of 15 to 20 Gy is delivered in the initial tumour for good responders. Salvage surgery is necessary in case of poor response. The organs at risk to be considered are bladder, femur heads, small intestine and vulva. The objective of this work is to summarize the epidemiological and radio-anatomic and prognostic characteristics of this tumour. The conformal radiotherapy technique is illustrated by a case report.

La EC es una inflamación crónica y transmural, que afecta todas las capas del intestino y puede llegar a incluir a uno o varios segmentos del tracto digestivo, con localización predominante en íleon terminal, colon y región perianal. Los tramos entre zonas afectadas histológicamente son normales. Ambos trastornos se acompañan de manifestaciones tanto digestivas como extradigestivas en ocasiones: articulares, muco-cutáneas, hepatobiliares, nefro-urológicas y oculares principalmente. Tienen un curso crónico, donde se alternan fases de actividad con fases de latencia. Generalmente, con una buena anamnesis, y la ayuda de datos clínicos, analíticos, endoscópicos, histopatológicos y de distintas técnicas de imagen se puede llegar a un diagnóstico diferencial entre CU y EC. Los índices de actividad de la enfermedad son de gran utilidad para el adecuado control evolutivo.

    We describe the medical-surgical management of a patient with a complex inflammatory bowel disease who developed 2 acute episodes of pyoderma gangrenosum and enterocutaneous fistulas after ileal pouch-anal anastomosis for ulcerative colitis. The rarity of this postsurgical complication is emphasized. A good response to topical tacrolimus was achieved in cutaneous wounds. A less favorable response to infliximab was achieved in the abdominal fistulas, requiring surgical excision of the pouch. PMID:17498458

    Anal intraepithelial lesions are caused by chronic infection with oncogenic types of human papillomavirus. Their incidence and prevalence are increasing, especially among patients with HIV infection. Their natural history is not well known, but high-grade intraepithelial lesions seem to have an important risk to progress to squamous cell carcinoma. Their treatment can be achieved by many ways (surgery, coagulation, imiquimod, etc.) but there is a high rate of recurrent lesions. Pretherapeutic evaluation should benefit from high-resolution anoscopy. Periodic physical examination and anal cytology may probably be interesting for screening the disease among patients with risk factors. Vaccine against oncogenic types of papillomavirus may prevent the development of anal intraepithelial neoplasia. PMID:23122632

    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.

    Background: Clostridium difficile colitis is associated with increased age, antibiotic usage, and hospitalization. Severe C. difficile colitis refractory to medical therapy may require surgical intervention including subtotal colectomy. We initiated an adjuvant intracolonic vancomycin (ICV) enema protocol for inpatients with severe C. difficile colitis and compared the response to this therapy in patients from the community and nursing homes.

  10. CT evaluation of infectious colitis

    International Nuclear Information System (INIS)

    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)

    The weakly beta-hemolytic porcine spirochete Brachyspira murdochii is considered a normal intestinal commensal. In the present study, however, a field case of B murdochii–associated catarrhal colitis was identified in a pig, as characterized by extensive spirochetal colonization of the surface...... epithelium. Experimentally, 8 weaned pigs were challenged with the B murdochii isolate, reproducing catarrhal colitis in 2 animals. By applying fluorescent in situ hybridization using a species-specific oligonucleotide probe targeting 23S rRNA, B murdochii organisms were found in high numbers and were...... closely associated with the surface epithelium in the pigs with catarrhal colitis. The results indicate that, when present in high numbers, B murdochii is low pathogenic for pigs....

    International Nuclear Information System (INIS)

    Endoscopic retrograde cholangiography (ERC) was performed in 28 patients with hepatobiliary disease associated with ulcerative colitis. The films were reviewed and correlated with diagnoses at liver biopsy. Thirteen patients with extrahepatic as well as intrahepatic bile duct abnormalities had characteristic cholangiographic findings compatible with sclerosing cholangitis, together with cholangiocarcinoma in one patient. Six patients had intrahepatic bile duct involvement only, and the cholangiographic abnormalities differed from those of sclerosing cholangitis. In 5 of these patients cirrhosis of the liver was found at biopsy or clinically. The result indicates that in patients with hepatobiliary disease suggested in association with ulcerative colitis, ERC gives valuable information. (Auth.)

    2015-12-01

    Perianal disease is a common complication of inflammatory bowel disease (IBD). It includes different conditions from more severe and potentially disabling ones, such as abscesses and fistulas, to more benign conditions such as hemorrhoids, skin tags and fissures. Most literature has been focused on anal sepsis and fistulae, as they carry the majority of disease burden and often alter the natural course of the disease. Hemorrhoids and anal fissures in patients with IBD have been overlooked, although they can represent a challenging problem. The management of hemorrhoids and fissures in IBD patients may be difficult and may significantly differ compared to the non-affected population. Historically surgery was firmly obstructed, and hemorrhoidectomy or sphincterotomy in patients with associated diagnosis of IBD was considered harmful, although literature data is scant and based on small series. Various authors reported an incidence of postoperative complications higher in IBD than in the general populations, with potential severe events. Considering that a spontaneous healing is possible, the first line management should be a medical therapy. In patients non-responding to conservative measures it is possible a judicious choice of surgical options on a highly selective basis; this can lead to acceptable results, but the risk of possible complications needs to be considered. In this review it is analyzed the current literature on the incidence, symptoms and treatment options of hemorrhoids and anal fissures in patients with Crohn's disease and ulcerative colitis.

METHODS: 30 Wistar male rats were studied, weighing between 260 and 300g, divided in three groups of 10 individuals. The distribution of the groups was made as follows: Group I (n 10, named control group, received a standard diet during the whole experiment. Group II (n 10, named colitis group, received an equally standard diet during the whole experiment and 8% acetic acid that induced inflammatory colitis. Group III (n 10, named colitis + fiber, received a standard diet with addition of dietetic fiber ( 10 g of seeds and peels of Plantago ovata for each 90 g of standard diet and 8% acetic acid that induced inflammatory colitis. The experiment lasted 21 days and the inflammatory colitis induction was introduced on the fourteenth day in groups II and III. Twenty-one days after the start of the experiment the animals were sacrificed and total colectomies were performed. The specimens were submitted to stereologic and histological analysis, and they statistically evaluated by the Mann-Whitney test. The weight variation of the animals was also measured during the experiment. The studied parameters were: mucosa, muscularis mucosa, submucosa, lamina propria, epithelial and proper epithelial layer partial volumes. CONCLUSION: The results, through stereologic, histological and weight analysis, lead us to conclude that the addition of Plantago ovata (dietetic fiber prevents the alterations caused by the 8% acetic acid induced colitis in the experimental animals.

    AIM: To describe a new clinical and pathological subtype of microscopic colitis in children.METHODS: A selected group of children with abdominal pain, constipation and/or diarrhoea showing discrete or no macroscopic abnormalities on endoscopy was described.RESULTS: Multiple biopsies of colon showed large mononuclear clear cells in lamina propria of mucous membrane provided that good quality histological sections were performed and observed under a higher magnification. Otherwise, they could be misinterpreted as artefacts. Their presence in routine histology might suggest a systemic storage disease (Whipple's disease), and neuronal intestine dysplasia.Using immunohistochemical staining and electron microscopy we confirmed their origin from CD68 positive mononuclear macrophages.CONCLUSION: The presence of large clear cells is a constant microscopic feature. Failure of transient large bowel stationary macrophages plays a role in the pathogenesis of this benign microscopic clear cell colitis,sometimes coexisting with allergy.

    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.

    AIM: Hypertrophied anal papillae and fibrous anal polyps are not given due importance in the proctology practice.They are mostly ignored being considered as normal structures. The present study was aimed to demonstrate that hypertrophied anal papillae and fibrous anal polyps could cause symptoms to the patients and that they should be removed in treatment of patients with chronic fissure in anus.METHODS: Two groups of patients were studied. A hundred patients were studied in group A in which the associated fibrous polyp or papillae were removed by radio frequency surgical device after a lateral subcutaneous sphincterotomy for relieving the sphincter spasm. Another group of a hundred patients who also had papillae or fibrous polyps, were treated by lateral sphincterotomy alone. They were followed up for one year.RESULTS: Eighty-nine percent patients from group A expressed their satisfaction with the treatment in comparison to only 64% from group B who underwent sphincterotomy alone with the papillae or anal polyps left untreated. Group A patients showed a marked reduction with regard to pain and irritation during defecation (P= 0.0011),pricking or foreign body sensation in the anus (P = 0.0006)and pruritus or wetness around the anal verge (P = 0.0008).CONCLUSION: Hypertrophied anal papillae and fibrous anal polyps should be removed during treatment of chronic anal fissure. This would add to effectiveness and completeness of the procedure.

    Johannes Meier; Andreas Sturm

    2011-01-01

    Ulcerative colitis (UC) is a chronic disease featuring recurrent inflammation of the colonic mucosa. The goal of medical treatment is to rapidly induce a steroid-free remission while at the same time preventing complications of the disease itself and its treatment. The choice of treatment depends on severity, localization and the course of the disease. For proctitis, topical therapy with 5-aminosalicylic acid (5-ASA) compounds is used. More extensive or severe disease should be treated with oral and local 5-ASA compounds and corticosteroids to induce remission. Patients who do not respond to this treatment require hospitalization. Intravenous steroids or, when refractory, calcineurin inhibitors (cyclosporine, tacrolimus), tumor necrosis factor-α antibodies (infliximab) or immunomodulators (azathioprine, 6-mercaptopurine) are then called for. Indications for emergency surgery include refractory toxic megacolon, perforation, and continuous severe colorectal bleeding. Close collaboration between gastroenterologist and surgeon is mandatory in order not to delay surgical therapy when needed. This article is intended to give a general, practice- orientated overview of the key issues in ulcerative colitis treatment. Recommendations are based on published consensus guidelines derived from national and international guidelines on the treatment of ulcerative colitis.

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.

  2. Acute colitis: differential diagnosis using multidetector CT

    International Nuclear Information System (INIS)

    Aim: To investigate the utility of multidetector CT (MDCT) in helping to establish the underlying cause of acute colitis. Methods and materials: All patients who had acute colitis with a well-identified cause and underwent abdomen 64-MDCT were included in the study. MDCT images were retrospectively analysed in a blinded fashion and the CT findings were correlated with the eventual aetiological diagnosis. Results: The study population included 105 patients. Acute colitis was related to inflammatory bowel disease in 43 cases. MDCT was used to identify six relevant signs of inflammatory colitis: the “comb” sign (p < 0.001), enlarged lymph nodes (p < 0.001), abscess (p = 0.026), fibro-fatty infiltration (p = 0.007), small bowel involvement (p < 0.001), and the absence of an “empty colon” sign (p = 0.045). Multivariate logistic regression analysis identified three independent signs of inflammatory colitis: the “comb” sign, small bowel involvement, and enlarged lymph nodes. Acute colitis was related to bacterial infection in 35 cases. Five signs were significantly associated with infectious colitis: continuous distribution (p = 0.020), an “empty colon” sign (p = 0.002), absence of fat stranding (p = 0.013), and absence of a “comb” sign (p = 0.010) and absence of enlarged lymph nodes (p = 0.035). Multivariate analysis identified three independent signs: the “empty colon” sign and absence of fat stranding and of a “comb” sign. The remaining causes were ischaemic colitis (n = 21) and drug-related colitis (n = 6). MDCT examination provided five relevant signs of ischaemic colitis: fat stranding (p = 0.002), discontinuous distribution (p < 0.001), and absence of enlarged lymph node (p < 0.001), a “comb” sign (p = 0.006) and small bowel involvement (p = 0.037). Conclusions: MDCT provides certain suggestive signs that may be helpful in distinguishing the underlying aetiological cause of acute colitis

  3. Probiotics and prebiotics in ulcerative colitis.

    2016-02-01

    The intestinal microbiota is one of the key players in the etiology of ulcerative colitis. Manipulation of this microflora with probiotics and prebiotics is an attractive strategy in the management of ulcerative colitis. Several intervention studies for both the induction and maintenance of remission in ulcerative colitis patients have been performed. Most of these studies evaluated VSL#3 or E. Coli Nissle 1917 and in general there is evidence for efficacy of these agents for induction and maintenance of remission. However, studies are frequently underpowered, lack a control group, and are very heterogeneous investigating different probiotic strains in different study populations. The absence of well-powered robust randomized placebo-controlled trials impedes the widespread use of probiotics and prebiotics in ulcerative colitis. However, given the promising results that are currently available, probiotics and prebiotics may find their way to the treatment algorithm for ulcerative colitis in the near future. PMID:27048897

    William E. Carter, MD, MPH

    2014-07-01

    Full Text Available Across the medical literature, delayed diagnosis and treatment leads to more costly and worse outcomes. Rehabilitation patients, especially those with polytrauma, often have a complex mixture of medical, social, and psychological health problems that can impair effective diagnosis and treatment. The case presentation describes the procession toward the diagnosis of ulcerative colitis in a preinjury asymptomatic male, suggesting a potential mechanism for its emergence and describing the effect of delayed diagnosis on the efficiency of rehabilitative care. As such, the differential diagnosis for early posttraumatic diarrhea should remain broad, particularly if unexplained or ineffectively controlled.

    Most anal cancers are caused by persistent infections with carcinogenic human papillomaviruses (HPV). Similar to cervical carcinogenesis, the progression from HPV infection to anal cancer goes through precancerous lesions that can be treated to prevent invasion. In analogy to cervical cytology, anal cytology has been proposed as a screening tool for anal cancer precursors in high-risk populations. We analyzed the inter-observer reproducibility of anal cytology in a population of 363 HIV-infec...

    2011-05-01

    Full Text Available Abstract Background Microscopic colitis presents with similar symptoms to classic inflammatory bowel diseases. Osteoporosis is a common complication of Crohn's disease but there are no data concerning bone metabolism in microscopic colitis. Aims The aim of the present study was to evaluate bone density and metabolism in patients with microscopic colitis. Methods Fourteen patients microscopic colitis were included in the study, and 28 healthy persons and 28 age and gender matched Crohn's disease patients were enrolled as controls. Bone mineral density was measured using dual x-ray absorptiometry at the lumbar spine, femoral neck and the radius. Serum bone formation and bone resorption markers (osteocalcin and beta-crosslaps, respectively were measured using immunoassays. Results Low bone mass was measured in 57.14% patients with microscopic colitis. Bone mineral density at the femoral neck in patients suffering from microscopic colitis and Crohn's disease was lower than in healthy controls (0.852 ± 0.165 and 0.807 ± 0.136 vs. 1.056 ± 0.126 g/cm2; p 2; p 2. Mean beta-crosslaps concentration was higher in microscopic colitis and Crohn's disease patients than controls (417.714 ± 250.37 and 466.071 ± 249.96 vs. 264.75 ± 138.65 pg/ml; p Conclusions Low bone mass is frequent in microscopic colitis, and alterations to bone metabolism are similar to those present in Crohn's disease. Therefore, microscopic colitis-associated osteopenia could be a significant problem in such patients.

  10. Modern management of anal fistula.

    Limura, Elsa; Giordano, Pasquale

    2015-01-01

    Ideal surgical treatment for anal fistula should aim to eradicate sepsis and promote healing of the tract, whilst preserving the sphincters and the mechanism of continence. For the simple and most distal fistulae, conventional surgical options such as laying open of the fistula tract seem to be relatively safe and therefore, well accepted in clinical practise. However, for the more complex fistulae where a significant proportion of the anal sphincter is involved, great concern remains about damaging the sphincter and subsequent poor functional outcome, which is quite inevitable following conventional surgical treatment. For this reason, over the last two decades, many sphincter-preserving procedures for the treatment of anal fistula have been introduced with the common goal of minimising the injury to the anal sphincters and preserving optimal function. Among them, the ligation of intersphincteric fistula tract procedure appears to be safe and effective and may be routinely considered for complex anal fistula. Another technique, the anal fistula plug, derived from porcine small intestinal submucosa, is safe but modestly effective in long-term follow-up, with success rates varying from 24%-88%. The failure rate may be due to its extrusion from the fistula tract. To obviate that, a new designed plug (GORE BioA®) was introduced, but long term data regarding its efficacy are scant. Fibrin glue showed poor and variable healing rate (14%-74%). FiLaC and video-assisted anal fistula treatment procedures, respectively using laser and electrode energy, are expensive and yet to be thoroughly assessed in clinical practise. Recently, a therapy using autologous adipose-derived stem cells has been described. Their properties of regenerating tissues and suppressing inflammatory response must be better investigated on anal fistulae, and studies remain in progress. The aim of this present article is to review the pertinent literature, describing the advantages and limitations of

    Full Text Available Left ventricular thrombi usually occur in the setting of an acute myocardial infarction, left ventricular aneurysm, or dilated cardiomyopathy. In the absence of ventricular wall motion abnormalities, they are rare. This report describes a patient with ulcerative colitis in whom two-dimensional echocardiography revealed a left intraventricular mass. Thrombosis in ulcerative colitis is a serious condition and can occur in a very young population. This case also shows that left ventricular thrombi can occur in the active setting of ulcerative colitis.

    Hugh James Freeman

    2012-01-01

    Full Text Available In the past, there has been considerable focus on a host of drugs and chemicals that may produce colonic toxicity. Now, a variety of new biological monoclonal antibody agents, usually administered by infusion, have appeared in the clinical realm over the last decade or so to treat different chronic inflammatory or malignant disorders.For some of these agents, adverse effects have been documented, including apparently new forms of immune-mediated inflammatory bowel disease. In some, only limited symptoms have been recorded, but in others, severe colitis with serious complications, such as bowel perforation has been recorded. In others, adverse effects may have a direct vascular or ischemic basis, while other intestinal effects may be related to a superimposed infection. Some new onset cases of ulcerative colitis or Crohn’s disease may also be attributed to the same agents used to treat these diseases, or be responsible for disease exacerbation. Dramatic and well documented side effects have been observed with ipilimumab, a humanized monoclonal antibody developed to reduce and overcome cytotoxic T-lymphocyte antigen 4, a key negative feedback regulator of the T-cell anti-tumor response. This agent has frequently been used in the treatment of different malignancies, notably, malignant melanoma. Side effects with this agent occur in up to 40% and these are believed to be largely immune-mediated. One of these is a form of enterocolitis that may be severe, and occasionally, fatal. Other agents include rituximab (an anti-CD20 monoclonal antibody, bevacizumab (a monoclonal antibody against the vascular endothelial growth factor and anti-tumor necrosis factor agents, including infliximab, adalimumab and etanercept.

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.)

    There have only been a few reports on lansoprazoleassociated collagenous colitis. Colonic mucosa of collagenous colitis is known to be endoscopically normal. We present a case of collagenous colitis where the mucosa showed diffuse cloudiness mimicking ulcerative colitis. A 70-year-old woman developed watery diarrhea four to nine times a day. She had interstitial pneumonia at 67 and reflux esophagitis at 70 years. Lansoprazole 30 mg/d had been prescribed for reflux esophagitis for nearly 6 mo. Lansoprazole was withdrawn due to its possible side effect of diarrhea. Colonoscopy disclosed diffuse cloudiness of the mucosa which suggested ulcerative colitis. Consequently sulfasalazine 2 g/d was started. The patient's diarrhea dramatically disappeared on the following day. However, biopsy specimens showed subepithelial collagenous thickening and infiltration of inflammatory cells in the lamina propria, confirming the diagnosis of collagenous colitis. One month after sulfasalazine therapy was initiated, colonoscopic and histological abnormalities resolved completely. Five months later the diarrhea recurred. The findings on colonoscopy and histology were the same as before, confirming a diagnosis of collagenous colitis relapse. We found that the patient had begun to take lansoprazole again 3 mo ahead of the recent diarrhea. Withdrawal of lansoprazole promptly resolved the diarrhea. Endoscopic and histological abnormalities were also completely resolved, similar to the first episode. Retrospectively, the date of commencement of sulfasalazine and discontinuation of lansoprazole in the first episode was found to be the same. We conclude that this patient had lansoprazole-associated collagenous colitis.

    Full Text Available Physical exercise has been related with both beneficial effects on the gastrointestinal tract as with adverse effects on the latter. Gastrointestinal bleeding is one of these. In general, gastrointestinal bleeding is transient and mild. However, some cases caused by intestinal ischemia can sometimes be more serious due to the amount of bleeding and the presence of mucosal lesions. We present the case of a patient with abdominal pain and rectal bleeding caused by an extensive ischemic colitis due to vigorous physical exercise.El ejercicio físico se ha relacionado con beneficios sobre el tracto digestivo así como efectos adversos sobre el mismo. El sangrado gastrointestinal es una de las complicaciones descritas asociadas al mismo. Por lo general, la hemorragia digestiva en estos casos es transitoria y leve.

    Microscopic colitis is a common cause of chronic, nonbloody diarrhea. Microscopic colitis is more common in women than men and usually affects patients in their sixth and seventh decade. This article reviews the etiology and medical management of microscopic colitis. The etiology of microscopic colitis is unknown, but it is associated with autoimmune disorders, such as celiac disease, polyarthritis, and thyroid disorders. Smoking has been identified as a risk factor of microscopic colitis. Exposure to medications, such as non-steroidal anti-inflammatory drugs, proton pump inhibitors, and selective serotonin reuptake inhibitors, is suspected to play a role in microscopic colitis, although their direct causal relationship has not been proven. Multiple medications, including corticosteroids, anti-diarrheals, cholestyramine, bismuth, 5-aminosalicylates, and immunomodulators, have been used to treat microscopic colitis with variable response rates. Budesonide is effective in inducing and maintaining clinical remission but relapse rate is as high as 82% when budesonide is discontinued. There is limited data on management of steroid-dependent microscopic colitis or refractory microscopic colitis. Immunomodulators seem to have low response rate 0%-56% for patients with refractory microscopic colitis. Response rate 66%-100% was observed for use of anti-tumor necrosis factor (TNF) therapy for refractory microscopic colitis. Anti-TNF and diverting ileostomy may be an option in severe or refractory microscopic colitis. PMID:26269669

    Full Text Available Although a minor anorectal malformation the delay in diagnosis and treatment of anal stenosis may result in significant early or late complications. Early inspection of the perineum in the neonate to pick up and correct anorectal malformation improves long term outcome but this requires proper anal examination or it could be missed. We present and discuss a case of delayed diagnosis of congenital anal stenosis (a low anorectal anomaly with an imminent colonic perforation. Severe anal stenosis will always require examination under anesthesia with graded Hegar's dilatation followed by postoperative maintenance. The Hegar dilator is thus both diagnostic and therapeutic in congenital anal stenosis.

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.

  1. Carcinoma of the anal canal

    International Nuclear Information System (INIS)

    There are many unresolved issues in the management of epidermoid anal canal cancer, although substantial progress has been made in gaining acceptance of techniques that preserve anal function. Resolution of the most basic questions would require formal comparisons of radical surgery, radiation therapy alone, and combined modality therapy. However, patients are unlikely to participate in studies in which one or more options would offer a chance to avoid a colostomy. Informal comparisons of published series suggest that modern radiation therapy and combined modality therapy give survival rates similar to those reported following radical surgery. Other questions being addressed include identification of optimal radiation techniques, detailed exploration of the mechanisms, efficacy, and toxicity of drug and radiation combinations, and identification of effective systemic chemotherapy. All studies are made difficult by the relative rarity of this tumor. Even without formal clinical trials, however, the series reported the use of either radiation therapy alone or combined modality therapy as the initial treatment for epidermoid anal canal carcinoma, thereby preserving anal function whenever possible and reserving radical surgery for the patient with residual carcinoma

    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.

    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.

    Ulcerative colitis (UC) is a chronic, idiopathic, inflammatory large bowel disease with recurrent variable periods of exacerbation. The aim of the current study is to evaluate the correlation of UCEIS with fecal calprotectin (FC) level to assess disease activity in UC patients in order to determine whether FC can prognosticate clinical outcome and disease activity of UC instead of colonoscopic evaluation. Our endoscopic investigations revealed the extension of UC as the following: proctitis (11.6%), procto-sigmoiditis (18.5%), left-sided colitis (15.8%), extensive colitis (11.7%), and normal endoscopy (42.4%). Conclusively, we suggest that FC can be used as a reliable tool to evaluate disease activity in ulcerative colitis patients. Moreover, our findings indicate a significant correlation between FC level and mucosal healing. PMID:25366383

    2004-01-01

    The anatomy of the internal anal sphincter and surrounding structures was investigated in 24 cadavers using a surgical microscope (6-25 x magnification). An understanding of the anatomy of the internal anal sphincter is helpful in avoiding complications during surgical procedures in the anorectal region. The external anal sphincter was composed of three ellipsoid rings of skeletal muscle (subcutaneous, superficial, and deep) that encircle the anal canal; in contrast, we found that the internal anal sphincter was composed of flat rings of smooth muscle bundles stacked one on top of the other, like the slats of a Venetian blind. In each anal canal, the average number of ring-like slats observed was 26.33 +/- 2.93 (range = 20-30) and each was covered by its own fascia. The smooth muscle fibers and fascia coalesced at three equidistant points around the anal canal to form three columns that extended distally into the lumen and differed in form from the other anal columns. When viewed from an anterior position, the columns were located anteriorly at the observer's right (5 o'clock position), posteriorly at the right (1 o'clock position), and laterally at the left (9 o'clock position). This heretofore unreported anatomy of the internal anal sphincter may play an important role in closing off the lumen of the anal canal and maintaining bowel continence. PMID:14695582

    2016-01-01

    Introduction Well leg compartment syndrome (WLCS) is an uncommon and severe complication that occurs after colorectal surgery in the lithotomy position. Presentation of case The current patient was a 28-year-old male suffering from ulcerative colitis. He was underwent elective proctectomy, including ileal J pouch formation and anal anastomosis with temporary loop ileostomy. The ileoanal pouch procedure was quite difficult, and during this procedure, the high lithotomy and head down tilt positions were continued for 255 min. After the operation, the patient complained of severe cramping pain, swelling and serious tenderness on palpation in both legs. On the first postoperative day, the patient's complaints gradually worsened. The intra-compartmental pressure was measured, and WLCS was diagnosed. Emergency bilateral fasciotomy was performed. Initially, the patient had a sensory deficit and analgesia, however, his sensory disturbance and pain had almost recovered two months after fasciotomy by rehabilitation. Discussion In the current case, the important factors associated with the development of WLCS are thought to be a prolonged operative time in which the patient is placed in the high lithotomy position during ileoanal pouch procedure. Conclusion We would thus like to emphasize that operations for the ileoanal pouch procedure to treat ulcerative colitis have a high potential for inducing WLCS, because it usually requires a prolonged operative time in which the patient remains in the high lithotomy position.

  13. Conservative management of anal leiomyosarcoma

    International Nuclear Information System (INIS)

    Leiomyosarcomas of the large intestine are unusual neoplasms, comprising less than 0.1% of all malignancies of the colon and rectum. Six cases of leiomyosarcoma of the anus have been reported. The optimal treatment for this neoplasm is not known. The standard surgical approach is abdominoperineal resection. The authors report the seventh case of this rare neoplasm and outline its treatment using local excision and iridium 192 brachytherapy in an attempt to preserve the anal sphincter. In selected patients, conservative surgery followed by radiation therapy may be an alternative to radical surgery, with the goals of local control of the disease and anal sphincter preservation. However, more experience is needed before this approach could be recommended routinely

    Full Text Available There are around 5,000 new cases of anal canal cancer each year in the United States. It is of particular risk in HIV-positive populations. Many cases are related to persistent infection with human papillomavirus (HPV. The treatment of anal cancer has progressed from abdominoperineal resection mandating permanent colostomy in the 1940s through the 1970s to modern chemoradiation with sphincter preservation in around 80% of patients, even with locally advanced disease. The evolution of the treatment paradigm of this disease is a model for the treatment of malignant disease with organ preservation. Multiple randomized trials have been conducted to guide this evolution. Technological developments in the delivery of radiotherapy and anti-cancer pharmaceuticals harbor hope for further improvements in outcomes with possible reductions in toxicity and increases in tumor control. Perhaps most inspiring is the recent development of HPV vaccines that

    2000-01-01

    Full Text Available After fecal diversion, nonspecific colitis may be seen in the defunctionalized colon. The purpose of this prospective study is to identify specific findings that could help in the differential diagnosis between diversion colitis and other inflammatory bowel diseases in order to avoid inappropriate diagnosis and therapy. It was studied, prospectively, thirteen consecutive patients from two public hospitals of Rio de Janeiro who had undergone temporary colostomy for indications other than inflammatory bowel disease. They were submitted to endoscopy with biopsy of both proximal and distal colorectal segments, and prospectively evaluated before and after restoration of intestinal continuity. Endoscopy with biopsy of both proximal and distal excluded colorectal segments showed a nonspecific mucosal and submucosal inflammation, resembling ulcerative colitis ( p < 0.01. There was endoscopic resolution in all patients once restoration of intestinal continuity was established (p < 0.01 and also histologic improvement after the stoma closure. In conclusion there are no specific findings that make possible an unequivocal distinction between diversion colitis and other nonspecific inflammatory diseases. Diagnosis should be achieved if after stoma closure occur remission of endoscopic large bowel inflammatory signs with improvement in mucosal histologic appearance and prompt relief of clinical complaints.

    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

    2011-01-01

    The incidence of anal cancer in HIV-infected men who have sex with men (MSM) is highly elevated compared to the general population, as is the incidence of its precursor lesion, high-grade anal intraepithelial neoplasia (HGAIN). MSM in general and other immunocompromised populations are also at higher risk. Treatment of HGAIN may prevent development of cancer, similar to the decrease in cervical cancers that has occurred since the advent of cervical cancer screening programs in women. Cervical cancer screening tools have been adapted and validated for screening, diagnosis, and treatment of anal HGAIN. Anal cancer screening programs have now been available for more than a decade, although they are not yet standards of care. Incorporating screening procedures into practice depends on the available resources in a particular community. This article discusses the procedures for anal cancer screening including cytology, digital anal rectal examinations, high-resolution anoscopy, and biopsy. PMID:22035526

    Introduction: Anal fissure causes significant morbidity in the population. It is proposed that elevated sphincter pressures may cause ischaemia of the anal lining and this may be responsible for the pain of anal fissures and their failure to heal. When pharmacologic therapy fails or fissures recur frequently, lateral internal sphincterotomy is the surgical treatment of choice.

    Full Text Available Los resultados del análisis estadístico sugieren una diferencia entre los dos grupos de enfermos en cuanto a manifestaciones psíquicas. El patrón de la personalidad de los enfermos con colitis ulcerativa idiopática es bien definido, y lo encontrado en el grupo del presente estudio, no difiere de lo escrito en la literatura mundial. En estos pacientes se han encontrado circunstancias psíquicas o físicas, que han tenido estrecha relación con la exacerbación y persistencia de la enfermedad, así como también la remisión de los síntomas aun por períodos muy largos, cuando el enfermo logra superar sus problemas emocionales serios. En conclusión, los resultados de esta investigación parecen confirmar que existe una relación estrecha entre las recurrencias de la enfermedad, los estados emocionales y la mejoría marcada, a veces por muchos años, al solucionar sus problemas.

    2013-01-01

    Background The endoribonuclease RNase-L is a type-I interferon (IFN)-regulatedcomponent of the innate immune response that functions in antiviral, antibacterial and antiproliferative activities. RNase-L produces RNA agonists of RIG-I-like receptors (RLRs), sensors of cytosolic pathogen-associated RNAs that induce cytokines including IFNβ. IFNβ and RLR signaling mediate protective responses against experimental colitis and colitis-associated cancer (CAC) and contribute to gastrointestinal (GI) homeostasis. Therefore, we investigated a role for RNase-L in murine colitis and CAC and its association with RLR signaling in response to bacterial RNA. Methods Colitis was induced in wild type (WT) and RNase-L-deficient mice (RNase-L−/−) by administration of dextran sulphate sodium (DSS). CAC was induced by DSS and azoxymethane (AOM). Histological analysis and immunohistochemistry were performed on colon tissue to analyze immune cell infiltration and tissue damage following induction of colitis. Expression of cytokines was measured by qRT-PCR and ELISA. Results DSS-treated RNase-L−/− mice exhibited a significantly higher clinical score, delayed leukocyte infiltration, reduced expression of IFNβ, TNFα, IL-1β and IL-18at early times post-DSS exposure and increased mortalityas compared to WT mice. DSS/AOM-treated RNase-L−/−mice displayed an increased tumor burden. Bacterial RNA triggeredIFNβproductionin an RNase-L-dependent manner and provided a potential mechanism by whichRNase-L contributes to the GI immune response to microbiota and protects against experimental colitis and CAC. Conclusions RNase-L promotes the innate immune response to intestinal damage and ameliorates murine colitis and CAC. The RNase-L-dependent production of IFNβ stimulated by bacterial RNA may be a mechanism to protectagainst GI inflammatory disease. PMID:23567782

    2006-01-01

    Cytomegalovirus (CMV) colitis rarely occurs in immunocompetent patients. We report a case of disabling and life threatening diarrhea in an immunocompetent elderly woman due to CMV colitis. The diagnosis of CMV was based on histological examination of tissues biopsied at colonoscopy, positive CMV antigen and high CMV-IgM titer in peripheral blood samples and a good response to systemic gancyclovir treatment.We conclude that CMV should be considered in the differential diagnosis of colitis in elderly immunocompetent patients.

    The inhibitory effects of vitamin D on colitis have been previously documented. Global vitamin D receptor (VDR) deletion exaggerates colitis, but the relative anticolitic contribution of epithelial and nonepithelial VDR signaling is unknown. Here, we showed that colonic epithelial VDR expression was substantially reduced in patients with Crohn’s disease or ulcerative colitis. Moreover, targeted expression of human VDR (hVDR) in intestinal epithelial cells (IECs) protected mice from developing...

    2014-01-01

    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.

    A radiologic investigation was performed in 26 patients subjected to colectomy, mucosal proctectomy and endorectal ileo-anal anastomosis after the creation of an ileal reservoir. The patients had suffered from ulcerative colitis or familial polyposis. The reservoir and its efferent leg was best demonstrated by contrast enema. The size and position of the reservoir and the efferent leg was demonstrated, and stenoses, abscesses and fistulae could be identified. Examination of the small bowel with a contrast medium showed slight dilatation of the ileum orally to the reservoir in all instances and one patient had a stenosis at the junction of the afferent leg of the reservoir. Erect and supine projections of the abdomen showed gas in the intestine and fluid levels in the reservoir. These radiographic findings should not be confused with ileus or pelvic abscess. Radiology was of great value in disclosing postoperative complications.

    2013-11-01

    Anal cancer is a rare malignancy of the distal gastrointestinal tract, often associated with human papillomavirus, the most common sexually transmitted infection worldwide. Currently available screening methods for anal intraepithelial neoplasia, a precursor for anal cancer, combine anal Papanicolaou cytology and high resolution anoscopy with biopsy of suspicious lesions. Significant barriers to establishing anal cancer screening programmes include the small number of healthcare professionals performing high resolution anoscopy and the lack of data showing that anal cancer screening can reduce morbidity and mortality related to anal carcinoma. Despite several controversies surrounding anal cancer screening, the rising incidence of this disease in some groups supports routine screening programmes in high-risk populations, especially in HIV-positive men who have sex with men. This review outlines the epidemiology of anal intraepithelial neoplasia and anal cancer and summarizes issues related to the introduction of anal cancer screening programmes. PMID:23970583

  7. Roentgenological and clinical studies on radiation colitis

    International Nuclear Information System (INIS)

    Fifty-six patients with radiation induced colitis in two institutes, 20 irradiated externally and 36 irradiated both externally and intracavitarily, were studied. The severity of radiation injuries was classified into 4 grades according to roentgenological and romanoscopical findings. Based on the charts of TAO system, radiation doses were calculated at the anterior rectal wall where maximum absorption dose of the colon was expected. The most frequent complaint was bloody stool which started about one year after irradiation. Onset of subjective symptoms was significantly delayed in milder cases (Grade II) than in more severe groups (Grades III, IV). Only minor injuries (Grade I) were noted in most of the externally irradiated, whereas more severe findings of radiation colitis were frequent in cervical cancer patients irradiated both intracavitarily and externally. The most common site involved in cervical cancer patients was the anterior colonic wall at the recto-sigmoid junction just behind the uterine cervix. In terms of relationship between time dose fractionation (TDF) and severity of radiation colitis, it was found that remarkable radiation injuries (Grades III, IV) occurred in the group of TDF value of 117 or more (more than 7500 rad). Therefore the author recommend the TDF value of 110 or less in cervical cancer cases with radiation therapy to keep radiation injury under Grade II. (author)

    The incidence of anal cancer is increasing. High risk populations include HIV-positive men who have sex with men (MSM), HIV-negative MSM, HIV-positive women and heterosexual men and women with a history of cervical cancer. HPV has been detected in over 90% of anal cancers. HPV16 is the most common genotype detected in about 70% of anal cancers. The quadrivalent HPV (qHPV) vaccine has been demonstrated to prevent vaccine associated persistent anal HPV infections as well as anal intraepithelial neoplasia grades 2-3 (AIN2+) in young MSM not previously infected. A retrospective analysis also suggests that qHPV vaccination of older MSM treated for AIN2+ may significantly decrease the risk of recurrence of the AIN2+. The HPV types detected in anal cancer are included in the 9-valent vaccine. Thus, the 9-valent HPV vaccine, when administered to boys and girls prior to the onset of sexual activity, should effectively prevent anal cancer. PMID:26933898

  20. Chemoradiation therapy for anal cancer

    International Nuclear Information System (INIS)

    Chemoradiation therapy for anal cancer was carried out in 58 patients using low-dose, continuous infusion of 5-fluorouracil (5-FU) with or without continuous infusion of cisplatin (cDDP) and external beam irradiation (chemoXRT). Thirty-nine patients received 5-FU chemoXRT resulting in a local control rate of 50% in those receiving a total dose of 60 Gy. The actuarial local control rate at 2 years was 77% after chemoXRT alone; overall local control was 67% at 5 years. In 18 patients receiving 5-FU plus cisplatin with radiation doses of 54-55 Gy, actuarial local control was 85% at 2 years. Fifteen patients failed chemoXRT, 13 of whom had abdominoperineal resection for salvage; the overall local control rate was 93% (54/58). The actuarial survival at 5 years was 81% for the 5-FU chemoXRT group and 94% at 2 years for the 5-FU plus cisplatin chemoXRT group; median follow-up was 54 and 20 months, respectively. Diarrhea and nausea were the most frequent early reactions and were ameliorated by limiting the duration of chemotherapy to 5 days/week and by using XRT techniques to exclude the small bowel from the radiation portal. Serious late radiation complications have not been observed and may be related to XRT fraction and the use of protracted chemotherapy infusion. The absence of late morbidity coupled with the high local control rate by the use of this chemoXRT program is an area to investigate for improving the therapeutic ratio for the treatment of anal cancers.

    2014-01-01

    Cytomegalovirus(CMV) is a common virus in patients with ulcerative colitis receiving immunosuppressive drugs. Many studies suggested that CMV infection is an exacerbating factor in patients with ulcerative colitis. The role of CMV in exacerbations of ulcerative colitis has been discussed. One of studies starting this discussion is an article entitled "CMV positive ulcerative colitis: A single center experience and literature review" by Kopylov et al. However, we think that there are some points that should be emphasized about the study. Especially, the small number of patients in the study has led to meaningless results. Large controlled prospective trials are needed to clarify the benefit of antiviral therapy for active ulcerative colitis patients.

    Antibiotic therapy disrupts the human intestinal microbiota. In some patients rapid overgrowth of the enteric bacterium Klebsiella oxytoca results in antibiotic-associated hemorrhagic colitis (AAHC). We isolated and identified a toxin produced by K. oxytoca as the pyrrolobenzodiazepine tilivalline and demonstrated its causative action in the pathogenesis of colitis in an animal model. Tilivalline induced apoptosis in cultured human cells in vitro and disrupted epithelial barrier function, consistent with the mucosal damage associated with colitis observed in human AAHC and the corresponding animal model. Our findings reveal the presence of pyrrolobenzodiazepines in the intestinal microbiota and provide a mechanism for colitis caused by a resident pathobiont. The data link pyrrolobenzodiazepines to human disease and identify tilivalline as a target for diagnosis and neutralizing strategies in prevention and treatment of colitis. PMID:25157164

    Substance P (SP) and the neurokinin-1 receptor (NK-1R) are involved in the development of colitis and mucosal healing after colonic inflammation. We studied whether SP modulates colonic fibrosis by using a chronic model of trinitrobenzenesulfonic acid (TNBS)-induced colitis in wild-type (WT) and NK-1R-deficient (NK-1R KD) mice. We found increased mRNA expression levels of collagen, vimentin, and the fibrogenic factors transforming growth factor β1 and insulin-like growth factor 1 in the chronically inflamed colons of WT mice treated with repeated intracolonic TNBS administrations. Fibrosis in TNBS-treated mice was also evident immunohistochemically by collagen deposition in the colon. Treatment of TNBS-exposed WT mice with the NK-1R antagonist CJ-12255 reduced colonic inflammation, colonic fibrosis, fibroblast accumulation, and expression levels of the fibrogenic factors. NK-1R knockout mice chronically exposed to TNBS had similar colonic inflammation compared with WT, but reduced colonic fibrosis, fibroblast accumulation, and expression levels of fibrogenic factors. Immunohistochemical staining also showed co-localization of NK-1R with fibroblasts in inflamed colons of mice and in colonic mucosa of patients with Crohn's disease. Exposure of human colonic CCD-18Co fibroblasts to SP (10 nmol/L) increased cell migration. SP stimulated collagen synthesis in CCD-18Co fibroblasts in the presence of transforming growth factor β1 and insulin-like growth factor 1, and this effect was reduced by Akt inhibition. Thus, SP, via NK-1R, promotes intestinal fibrogenesis after chronic colitis by stimulating fibrotic responses in fibroblasts. PMID:20889569

    AIM: To search the pathophysiological mechanism of diarrhea based on daily stool weights, fecal electrolytes,osmotic gap and pH.METHODS: 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.RESULTS: Fecal fluid sodium concentration was significantly increased in LC 58.11±5.38 mmol/L (P<0.01)and CC 54.14±8.42 mmol/L (P<0.05) than in CG 34.28±2.98 mmol/L. Potassium concentration in LC 74.65±5.29 mmol/L (P<0.01) and CC 75.53±8.78 mmol/L (P<0.05) was significantly less compared to CG 92.67±2.99 mmol/L.Chloride concentration in CC 36.07±7.29 mmol/L was significantly higher than in CG 24.11±2.05 mmol/L (P<0.05).Forty-four (86.7%) patients had a secretory diarrhea compared to fecal osmotic gap. Seven (13.3%) patients had osmotic diarrhea.CONCLUSION: 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.

  7. Changes in the absorption of bile acids after total colectomy in patients with an ileostomy or pouch-anal anastomosis

    International Nuclear Information System (INIS)

    Bile acid absorption was investigated using 75Se 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

    Ulcerative colitis (UC) is an inflammatory disease of the rectal and colonic mucosa and seems to result from a complex series of interactions between susceptibility genes, the environment and the immune system. Various components of the mucosal immune system are implicated in the immunopathogenesis of UC. Evidence from animal models also suggests that an altered immune response to the commensal microflora of the host plays a central role in the development of UC. So in this review, we elucidate the cells and molecules which are implicated in the immunopathogenesis of the disease from four aspects: antigens in the intestine, dendritic cells, toll like receptors and NF-κB in the UC.

    Full Text Available Anal fissure is one of the most common anorectal problems. Anal fissure is largely associated with high anal sphincter pressures and most treatment options are based on reducing anal pressures. There are many options to treat chronic fissures in ano. Some of them are non - surgical while the others are su rgical. The efficacy claimed by each of the prevalent method is very high but the inconsistencies and contraindications are equally strong. To date, lateral sphincterotomy has been favoured by most of the proctologists, because it is the least extensive su rgical procedure and is offering a long lasting relief in sphincter spasm. Various management technique are reviewed in this article along with Advancement flap for anterior fissure and a new method combining the age - old technique of Lord's manual dilatati on followed by radio surgery is also highlighted along with their complications. The addition of radio surgery is found useful for refreshing the edges of the fissure and to tackle pathologies namely sentinel pile, small internal piles or hypertrophied ana l papillae often found associated with chronic fissures. Revisiting the trends of treatment of chronic anal fissures, the most preferred options are the manual dilatation with radio surgery and the subcutaneous lateral anal sphincterotomy. Both methods are easy to perform, have negligible complications and no special setup is needed, except the radio surgical unit, in case of the first procedure.

    DSS induced colitis is a chronic inflammatory disease characterized by inflammation in the gastrointestinal tract, which destabilizes the gut and induces an uncontrolled immune response. Although DSS induced colitis is generally thought to develop as a result of an abnormally active intestinal immune system, its pathogenesis remains unclear. Gene associated with retinoid interferon induced mortality (Grim) 19 is an endogenous specific inhibitor of STAT3, which regulates the expression of proinflammatory cytokines. In this study, we investigated the influence of GRIM19 in a DSS induced colitis mouse model. We hypothesized that Grim19 would ameliorate DSS induced colitis by altering STAT3 activity and intestinal inflammation. Grim19 ameliorated DSS induced colitis severity and protected intestinal tissue. The expression of STAT3 and proinflammatory cytokines such as IL-1β and TNF-α in colon and lymph nodes was decreased significantly by Grim19. Moreover, DSS induced colitis progression in a Grim19 transgenic mouse line was inhibited in association with a reduction in STAT3 and IL-17 expression. These results suggest that Grim19 attenuates DSS induced colitis by suppressing the excessive inflammatory response mediated by STAT3 activation. PMID:27258062

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.

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

    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.

    Full Text Available OBJETIVO: Existe uma relação indireta entre a obstrução das vias aéreas em asma e a intensidade de falta de ar (dispneia. Uma escala visual analógica legendada de dispneia com escore de 0-3 pontos tem sido amplamente utilizada na avaliação da broncoconstrição, embora a percepção de tal obstrução seja muito variável. O objetivo deste estudo foi determinar se crianças e adolescentes são capazes de perceber a broncoconstrição aguda induzida por exercício (BAIE, bem como medir o poder discriminatório de uma escala visual analógica legendada de dispneia em relação à intensidade de BAIE. MÉTODOS: Estudo transversal com 134 crianças e adolescentes asmáticos que foram submetidos a um teste de broncoespasmo induzido por seis minutos de exercício em um cicloergômetro. A intensidade da dispneia foi determinada utilizando-se uma escala visual analógica legendada de dispneia antes de cada determinação de VEF1. A escala tem um escore de 0-3 pontos, com desenhos em uma sequência lógica variando entre "sem sintomas" e "dispneia grave". As variáveis foram determinadas no momento basal, assim como em 5, 10 e 20 minutos após o término do teste de exercício. A acurácia da escala de dispneia em detectar o grau de BAIE foi determinada através de curvas ROC para a queda de VEF1 após o exercício, usando pontos de corte de 10%, 20%, 30% e 40%.

    Differences in colonic secretory glycoconjugates (ie, mucin) between normal and ulcerative colitis-prone patients have been noted. Similar differences may occur in a corresponding primate model, the cotton-top tamarin (CTT), Saguinus oedipus, a New World monkey which suffers from spontaneous chronic colitis and colon cancer. Lectin reagents were used to characterize and compare colonic cell surface, cytoplasmic, and secretory glycoconjugates of 9 clinically healthy cotton-top tamarins, 7 colitis-susceptible, cancer-resistant tamarins (Callithrix jacchus, Saguinus fuscicollis), and 8 colitis and cancer-resistant primates (Aotus trivirgatus, Saimiri sciureus, Macaca fascicularis, and Macaca mulatta). Paraffin-embedded colonic sections were labeled with ten different biotinylated lectins and visualized by the avidin-biotin peroxidase (ABC) method. Significant differences were demonstrated in the pattern of lectin staining between the colitis-resistant and colitis-prone groups of primates. The differences were noted with Griffonia simplicifolia-I (GS-I), Dolichos biflorus agglutinin (DBA), peanut agglutinin (PNA) before and after neuraminidase, Ricinus communis agglutinin-I (RCA-I), soybean agglutinin (SBA), Ulex europaeus agglutinin-I (UEA-I), wheat germ agglutinin (WGA), and succinylated WGA (S-WGA). Significant differences between the CTT and phylogenetically related colitis-prone but cancer-resistant tamarins were demonstrated with SBA, UEA-I, and PNA after desialylation with neuraminidase. These results suggest that differences in colonic cellular glycoconjugates between colitis- and cancer-susceptible species versus colitis-susceptible, cancer-resistant species may be associated with risk of cancer.

    Full Text Available Joanna Y Chin, Theodore S Hong, Jennifer Y WoDepartment of Radiation Oncology, Massachusetts General Hospital, Boston, MA, USAAbstract: Anal cancer is a relatively rare malignancy, accounting for approximately 2% of gastrointestinal cancers. Concurrent chemoradiation with 5-fluorouracil/mitomycin remains the standard of care for the treatment of anal cancer. There is currently no proven role for platinum-based induction or adjuvant chemotherapy in anal cancer, even in cases of bulky disease. Multiple trials have shown that radiosensitization with concurrent chemotherapy is beneficial over radiation alone, and in particular, efforts to remove or substitute mitomycin from the chemoradiation regimen have been unsuccessful. Because local-regional control remains a challenge in the management of anal cancer, future studies will need to focus on radiation dose-escalation and/or addition of further chemotherapy or targeted agents. Patient selection, eg, with PET-CT or with biomarkers including HPV status, may be necessary to define patients who need more aggressive local treatment, ie, for patients with bulky disease, or to de-escalate treatment in others, ie, patients with early-stage, localized cancer.Keywords: anal cancer, chemoradiation, IMRT

    Because the normal faecal flora includes bacteria which can produce mucus-digesting glycosidases, it follows that increased digestion of colonic mucus by these bacterial enzymes could be important in the pathogenesis of ulcerative colitis. Faecal activities of potential mucus-degrading glycosidases have therefore been assayed in samples from patients with inflammatory bowel disease and normal controls. The enzymes alpha-D-galactosidase, beta-D-galactosidase, beta-NAc-D-glucosaminidase alpha-L-fucosidase and neuraminidase were assayed. Considerable glycosidase activity was present in most faecal samples. Similar activities of all the enzymes assayed were found in faeces from patients with ulcerative colitis, Crohn's disease and normal controls and there was no significant correlation with disease activity. These results imply that relapse of ulcerative colitis is not initiated by increased degradation of colonic mucus by faecal glycosidases but do not exclude a role for bacterial mucus degradation in the pathogenesis of ulcerative colitis.

    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.

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

  16. Desulfovibrio bacterial species are increased in ulcerative colitis.

    Rowan, Fiachra

    2012-02-01

    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.

    Pouch failure has been reported to occur after ileal pouch-anal anastomosis for Crohn's disease. We report two cases of patients with Crohn's disease, who underwent redo ileal pouch-anal anastomosis (redo-IPAA) combined with anti-TNF-α maintenance therapy, with good functional results. The first patient, a man with presumed ulcerative colitis, suffered pelvic fistula recurrence and anastomotic dehiscence. He underwent redo-IPAA, at which time longitudinal ulcers were found. Infliximab was started 4 days postoperatively and continued. The second patient, a woman treated for ulcerative colitis, underwent laparoscopic IPAA 8 years later. After the development of a pelvic fistula, twisted mesentery of the ileal pouch was found intraoperatively and Crohn's disease was diagnosed. Adalimumab therapy resulted in fistula closure. Redo-IPAA was performed to normalize the twisted mesentery of the ileal pouch. No complications have been observed in either patient, both of whom have experienced good functional results after closure of the covering stomas. PMID:24442570

    Rapid progress has been made to understand the pathophysiology of inflammatory bowel diseases and to identify new treatments. Interaction of the gut microbiota on the host inflammatory response has suggested that alternative therapies, such as probiotics, might have a complementary role in treating and preventing disease flares. Multiple probiotics and their formulations have been studied for both the induction and maintenance of remission of ulcerative colitis (UC); however, mainly Escherichia coli Nissle 1917 and VSL#3 have been shown to provide significant benefits for the prevention and treatment of mild to moderate UC. Although these data are promising, there is still a paucity of robust, randomized-controlled trials to suggest that probiotics be utilized as part of a standard treatment regimen. With continued research and a movement toward carefully selected, individualized management based on an individual's specific microbiota composition and function, probiotics may become an integral part of tailored therapy for UC.

    Full Text Available Abstract Background Human papillomavirus (HPV is well known as the major etiological agent for ano-genital cancer. In contrast to cervical cancer, anal cancer is uncommon, but is increasing steadily in the community over the last few decades. However, it has undergone an exponential rise in the men who have sex with men (MSM and HIV + groups. HIV + MSM in particular, have anal cancer incidences about three times that of the highest worldwide reported cervical cancer incidences. Discussion There has therefore traditionally been a lack of data from studies focused on heterosexual men and non-HIV + women. There is also less evidence reporting on the putative precursor lesion to anal cancer (AIN – anal intraepithelial neoplasia, when compared to cervical cancer and CIN (cervical intraepithelial neoplasia. This review summarises the available biological and epidemiological evidence for HPV in the anal site and the pathogenesis of AIN and anal cancer amongst traditionally non-high risk groups. Summary There is strong evidence to conclude that high-grade AIN is a precursor to anal cancer, and some data on the progression of AIN to invasive cancer.

    Although systemic steroids are highly efficacious in ulcerative colitis (UC),failure to respond to steroids sUll poses an important challenge to the surgeon and physician alike. Even if the life Lime risk of a fulminant UC flare is only 20%, this condition is potentially life threatening and should be managed in hospital. If patients fail 3 to 5 d of intravenous corticosteroids and optimal supportive care, they should be considered for any of three options: intravenous cyclosporine (2 mg/kg for 7 d, and serum level controlled),infliximab (5 mg/kg N,0-2-6 wk) or total colectomy.The choice between these three options is a medicalsurgical decision based on clinical signs, radiological and endoscopic findings and blood analysis (CRP, serum albumin).Between 65 and 85% of patients will initially respond to cyclosporine and avoid colectomy on the short term. Over 5 years only 50% of initial responders avoid colectomy and outcomes are better in patients naive to azathioprine (bridging strategy).The data on infliximab as a medical rescue in fulminant colitis are more limited although the efficacy of this anti tumor necrosis factor (TNF) monoclonal antibody has been demonstrated in a controlled trial. Controlled data on the comparative efficacy of cyclosporine and infliximab are not available at this moment. Both drugs are immunosuppressants and are used in combination with steroids and azathioprine, which infers a risk of serious, even fatal, opportunistic infections. Therefore,patients not responding to these agents within 5-7 d should be considered for colectomy and responders should be closely monitored for infections.

    We report a case of pouchitis and pre-pouch ileitis, and inflammation in the neo-terminal ileum proximal to the pouch, developed after restorative proctocolectomy for ulcerative colitis. A 35-year old female presented with fever and abdominal pain five weeks after ileostomy closure following proctocolectomy. Computed tomography showed collection of feces in the pouch and proximal ileum. A drainage tube was placed in the pouch perianally,and purulent feces were discharged. With antibiotic treatment, her symptoms disappeared, but two weeks later, she repeatedly developed fever and abdominal pain along with anal bleeding. Pouchscopy showed mucosal inflammation in both the pouch and the pre-pouch ileum. The mucosal cytokine production was elevated in the pouch and pre-pouch ileum. With antibiotic and corticosteroid therapy, her symptoms were improved along with improvement of endoscopic inflammation and decrease of mucosal cytokine production. The fecal stasis with bacterial overgrowth is the major pathogenesis of pouchitis and pre-pouch ileitis in our case.

  16. Hypersensitive prostaglandin and thromboxane response to hormones in rabbit colitis

    International Nuclear Information System (INIS)

    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 [14C]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 14C-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

    Full Text Available O Papilomavirus Humano (HPV anal tem alta prevalência e incidência na população. O objetivo deste trabalho é verificar a prevalência de HPV anal, bucal e genital em ambulatório público de Coloproctologia, com base no exame de captura hibrida. Foram estudados 64 pacientes atendidos no ambulatório geral de Coloproctologia do Hospital Heliópolis, no período de 22/11/2005 a 20/12/2005, onde foram levantados, de forma prospectiva, dados clínicos, pessoais e comportamentais, identificando o perfil do grupo como não sendo de risco para HPV. Nenhum paciente deste grupo veio à consulta com queixa ou apresentando sinais de HPV ou outra doença sexualmente transmissível. Foram colhidos para cada paciente um esfregaço com escova de boca, outro de vulva/pênis e outro do ânus. O resultado mostrou que 15,62% dos pacientes apresentaram HPV anal, bucal ou genital, sendo que 4,68% do total de pacientes apresentavam HPV anal, um paciente de alto risco associado ao HPV genital, outro misto e outro de baixo risco. Trinta por cento dos pacientes HPV+ apresentavam dor anal como queixa principal. A conclusão é que a prevalência de HPV anal, genital e bucal é elevada, sendo que 4,68% apresentavam HPV anal e daqueles HPV positivos 30% apresentavam dor anal na queixa principal.Anal Human Papilomavirus (HPV has a high prevalence and incidence in the population. The purpose of this project is to verify the prevalence of anal, oral and genital HPV at the Coloproctology Clinic, based on the hybrid capture exam. Sixty four patients were assisted at the clinic from November 22nd to December 20th 2005. Clinical, personal and behavioral data of the patients were set up in a prospective way. The group profile was identified as not being a risky one to HPV. No patient of this group, when was assisted, had complained of or had presented any symptoms of HPV or any other sexually transmitted disease (STD.

    2016-01-01

    BACKGROUND: Primiparous women have an increased risk of obstetric anal sphincter injury; because most of these patients deliver again, there are major concerns about mode of delivery: the risk of recurrent obstetric anal sphincter injury and the risk of long-term symptoms of anal incontinence....... Although an elective cesarean delivery protects against recurrent obstetric anal sphincter injury, it is uncertain how the second delivery affects the risk of long-term anal incontinence. OBJECTIVE: The purpose of this study was to evaluate whether the mode of delivery for a second pregnancy, after a...... documented obstetric anal sphincter injury at the time of first delivery, had a significant impact on the prevalence of anal and fecal incontinence in the long term. STUDY DESIGN: We performed a population-based questionnaire cohort study that evaluated anal and fecal incontinence, fecal urgency, and...

    Full Text Available La era actual se caracteriza por una búsqueda de la identidad del hombre, donde el pivote del cambio organizacional es el individuo; cambiar en este entorno depende, en gran medida, de los valores que imperen en la cultura de la organización. Este trabajo documental intenta identificar aquellos valores, condición sine-qua-non, para el logro de los objetivos de cambio y analizarlos a fin de determinar sus indicadores, con el objeto de presentar una herramienta a las organizaciones que les facilite adaptarse a los nuevos tiempos. Se encontró que los valores: Delegación, Comunicación, Colaboración, Participación y Aprendizaje, son esenciales en los cambios integrales de esta era. Se determinaron 20 indicadores de su presencia. Se concluye que con esta información cada ente puede elaborar instrumentos que le permitan saber si los valores requeridos están presentes y en caso contrario tomar decisiones que alineen a la organización alrededor de los valores humanistas planteados, incrementando así las posibilidades de éxito en el proceso de cambio y por ende, las posibilidades de supervivencia en esta nueva época.

    Full Text Available La presencia de plomo en el medio ambiente es un hecho indiscutible. Ello es objeto de gran interés sanitario pues repercute tanto en la salud de los animales como en la del ser humano. El plumbismo es una intoxicación que puede afectar a cualquier especie animal. En el ámbito de la fauna silvestre se asocia principalmente a la actividad cinegética en los humedales y a la ingestión de plomo metálico por parte de las aves que frecuentan estos ecosistemas. En España cada año mueren decenas de miles de aves acuáticas como consecuencia de la ingesta de perdigones de plomo. En los individuos capturados enfermos se pueden observar signos clínicos, mientras que a partir de muestras de cadáveres se obtienen datos sobre niveles tisulares de plomo. Sin embargo la evaluación de lesiones anatomopatológicas en animales de vida silvestre es difícil de realizar por la dificultad de encontrar animales recién muertos o afectados de un cuadro agudo mortal. La reproducción de esta patología en animales de experimentación se suele realizar en cisnes, palomas o patos, pero no en flamencos, por lo que no es usual disponer de datos histológicos en esta especie. En este trabajo presentamos la clínica, analítica y estudio microscópico de diferentes tejidos de un flamenco común (Phoenicopterus roseus muerto por plumbismo.

  10. Spontaneous colitis in Muc2-deficient mice reflects clinical and cellular features of active ulcerative colitis.

    Directory of Open Access Journals (Sweden)

    Ulf A Wenzel

    Full Text Available The colonic mucus layer plays a critical role in intestinal homeostasis by limiting contact between luminal bacteria and the mucosal immune system. A defective mucus barrier in animal models allows bacterial contact with the intestinal epithelium and results in spontaneous colitis. A defective mucus barrier is also a key feature of active ulcerative colitis (UC. Alterations in the immune compartment due to intestinal bacterial breach in mice lacking the colon mucus barrier have not been characterized and correlated to active UC.To characterize alterations in the immune compartment due to intestinal bacterial breach in Muc2-/- mice, which lack the colon mucus barrier, and correlate the findings to active UC.Bacterial contact with colon epithelium and penetration into colon tissue was examined in Muc2-/- mice and colon biopsies from patients with active UC using fluorescence microscopy and qPCR. Neutrophils, lymphocytes, CD103+ dendritic cell subsets and macrophages in colon from Muc2-/- mice and biopsies from UC patients were quantitated by flow cytometry.Inflamed UC patients and Muc2-/- mice had bacteria in contact with the colon epithelium. Bacterial rRNA was present in colonic mucosa in humans and Muc2-/- mice and in the draining lymph nodes of mice. Inflamed Muc2-/- mice and UC patients had elevated colon neutrophils, T cells and macrophages while a reduced frequency of CD103+ DCs was present in the inflamed colon of both mice and humans.The parallel features of the colon immune cell compartment in Muc2-/- mice and UC patients supports the usefulness of this model to understand the early phase of spontaneous colitis and will provide insight into novel strategies to treat UC.

  11. Magnetic resonance imaging of anal cancer

    International Nuclear Information System (INIS)

    AIM: The purpose of this study was to evaluate the magnetic resonance imaging (MRI) appearances of primary and recurrent anal carcinoma, and to demonstrate the commonest patterns of local and distant disease spread. METHODS: A retrospective review was performed of 27 cases of biopsy-proven anal carcinoma, where MRI was used for primary staging (9 patients) or suspected recurrence (18 patients). Two oncological radiologists reviewed the MR images, following a standardized approach. The size, extent and signal characteristics of the anal tumour were documented. Metastatic disease spread to lymph nodes, viscera and bone was recorded. In all, 7 patients with recurrent disease underwent surgery and subsequent histological correlation was performed. RESULTS: Primary and recurrent tumours were of high signal intensity relative to skeletal muscle on T2-weighted images (T2WI), and of low to intermediate signal intensity on T1-weighted images (T1WI). Lymph node metastases were of similar signal intensity to the anal cancer. Recurrent tumours were more locally advanced than primary tumours and extended into adjacent organs and the pelvic skeleton. Recurrent lymph node disease involved perirectal, presacral and internal iliac nodes more commonly than did primary lymph node disease. CONCLUSION: MRI can be useful in the primary staging of bulky tumours or of those with a long craniocaudal extent. MR has a role in the preoperative evaluation and surgical planning of cases of recurrent disease following radiotherapy

    Introduction: Anal fissure causes significant morbidity in the population. It is proposed that elevated sphincter pressures may cause ischaemia of the anal lining and this may be responsible for the pain of anal fissures and their failure to heal. When pharmacologic therapy fails or fissures recur frequently, lateral internal sphincterotomy is the surgical treatment of choice. Material and Methods: Retrospective analysis was done of admitted and operated patients of anal fissure by lateral anal internal sphincterotomy either by open or closed technique between April 2010 and November 2011 in Gujarat Medical Education & Research Society Medical College, Sola, Ahmedabad, India. The follow-up data of all patients was evaluated for pain relief, recurrence, wound infection, incontinence to flatus or stool or both for a period of up to 6 months. Results: Wound infection rate was 10.3% in open method and 4.2% in closed method. Incontinence to flatus was 8.3% in closed method and 3.4% in open method. This was temporary and controlled within a 1 week. Incontinence to stool was 3.4% in open method which was temporary and controlled within 2 weeks while none in closed method. None of the patients in either group had come with recurrence within 6 months follow-up. Conclusion: Lateral anal internal sphincterotomy is safe regarding long term incontinence and effective regarding recurrence. PMID:24551659

    2009-01-01

    A new, hypervirulent strain of Clostridium difficile, called NAP1/BI/027, has been implicated in C. difficile outbreaks associated with increased morbidity and mortality since the early 2000s. The epidemic strain is resistant to fluoroquinolones in vitro, which was infrequent prior to 2001. The name of this strain reflects its characteristics, demonstrated by different typing methods: pulsed-field gel electrophoresis (NAP1), restriction endonuclease analysis (BI) and polymerase chain reaction (027). In 2004 and 2005, the US Centers for Disease Control and Prevention (CDC) emphasized that the risk of C. difficile-associated diarrhea (CDAD) is increased, not only by the usual factors, including antibiotic exposure, but also gastrointestinal surgery/manipulation, prolonged length of stay in a healthcare setting, serious underlying illness, immune-compromising conditions, and aging. Patients on proton pump inhibitors (PPIs) have an elevated risk, as do peripartum women and heart transplant recipients. Before 2002, toxic megacolon in C. difficile-associated colitis (CDAC), was rare, but its incidence has increased dramatically. Up to twothirds of hospitalized patients may be infected with C. difficile. Asymptomatic carriers admitted to healthcare facilities can transmit the organism to other susceptible patients, thereby becoming vectors. Fulminant colitis is reported more frequently during outbreaks of C. difficile infection in patients with inflammatory bowel disease (IBD). C. difficile infection with IBD carries a higher mortality than without underlying IBD. This article reviews the latest information on C. difficile infection, including presentation, vulnerable hosts and choice of antibiotics, alternative therapies, and probiotics and immunotherapy. We review contact precautions for patients with known or suspected C. difficileassociated disease. Healthcare institutions require accurate and rapid diagnosis for early detection of possible outbreaks, to initiate

    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

    Following restorative proctocolectomy with an ileal pouch-anal anastomosis, the small bowel mucosa undergoes several specific histologic adaptions, which may be unrelated to the underlying disease or symptoms of pouchitis. An increase in intraepithelial lymphocytes (IELs) has not been described as part of this spectrum. Mucosal biopsies of the ileal pouch and afferent limb of 230 patients (mean age: 45.7y [18.3-74.7], gender [female/male]: 117/113) with a functioning ileal pouch-anal anastomosis (mean time since ileostomy closure: 10.8months) and associated clinically annotated outcome data were assessed for IELs/100 enterocytes. Forty-two patients (18.3%) showed an increase in IELs (≥20 IELs/100 enterocytes [range 20-39]), in pouch and/or afferent limb biopsies. Intraepithelial lymphocytosis was more commonly observed in afferent limb compared to pouch biopsies (18.8% vs 8.3%; P = .42) and in familial adenomatous polyposis compared to ulcerative colitis patients (16% vs 8%; P = 0.36), but neither difference reached statistical significance. No cases with increased IELs displayed severe villous blunting. Increased IELs were not significantly associated with age, sex, ethnicity, smoking history, time since ileostomy, use of antibiotics, biologic agents, anti-diarrheal agents or probiotics, C-reactive protein levels or differential white cell count. None of the 42 patients with increased IELs had positive celiac serology (anti-human tissue transglutaminase IgA [ELISA] with corresponding total serum IgA). Intraepithelial lymphocytosis in pouch biopsies may represent a subclinical response to an altered bacterial microenvironment. Pathologists should be aware that intraepithelial lymphocytosis is part of the spectrum of changes in pouch biopsies, and only rarely is due to celiac disease. PMID:27063473

  2. Pseudomembranous colitis: CT findings in children

    International Nuclear Information System (INIS)

    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.)

    The prevalence of cytomegalovirus in the burn population is high. However, its role in the clinical management of burn patients is still being defined. This report documents a 41-year-old man who developed cytomegalovirus (CMV) colitis after being admitted with a 72% burn. Before the administration of ganciclovir, the authors had difficulty controlling his quantitative wound cultures with serial debridements, topical agents, and systemic antibiotics for known pathogens, which led to graft loss. After the ganciclovir was given, his quantitative wound cultures improved without changing the authors' topical agents or systemic antibiotics and had improved graft take. Whether CMV infection alone contributed to an increased morbidity in this patient or the combination of bacteria/fungal infection with CMV led to a synergistic effect is still not clearly understood. CMV may have contributed to a dysfunction in his cell mediated immunity, which, in turn, lowered the bacterial and fungal load necessary to cause graft loss. Patients who continue to do poorly despite adequate treatment for known pathogens may need to be screened for CMV and treated. PMID:26056763

    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) [Deutsch] Wir untersuchten computertomographisch 109 Patienten mit 197 erkrankten Darmsegmenten. 81 Patienten litten an M. Crohn und 28 an Colitis ulcerosa.

Drei Radiologen bewerteten die Computertomographien und verglichen die Ergebnisse mit den konventionell-radiologischen Befunden. Bei den Patienten mit M. Crohn fanden wir in 26% der Faelle eine irregulaere aeussere Darmwand. Eine Darmwandverdickung lag in 82% vor und fand sich regelmaessig in Darmabschnitten mit floriden Veraenderungen

    2013-03-01

    Whether intestinal toxicity of preferential or selective COX-2 inhibitors is reduced compared with that of standard NSAIDs is controversial. A 26-year-old woman presented with acute abdominal pain and bloody diarrhoea a few days after beginning meloxicam treatment. Endoscopic examination of the colon showed erythematous and ulcerative lesions involving 15 cm of the left colon. No aetiology has been found for colitis. Diarrhea disappeared 1 week after meloxicam was stopped. Total colonoscopy 3 months and 2 years later was normal. The role of meloxicam in the etiology of colitis was considered plausible. This report and a few other cases in the literature suggest that cyclooxygenase-2 selective non-steroidal anti-inflammatory drug inhibitor toxicity should be investigated in case of unexplained acute colitis.

    BACKGROUND: Crohn's disease and ulcerative colitis are the two major forms of inflammatory bowel disease; treatment strategies have historically been determined by this binary categorisation. Genetic studies have identified 163 susceptibility loci for inflammatory bowel disease, mostly shared...... between Crohn's disease and ulcerative colitis. We undertook the largest genotype association study, to date, in widely used clinical subphenotypes of inflammatory bowel disease with the goal of further understanding the biological relations between diseases. METHODS: This study included patients from 49...... centres in 16 countries in Europe, North America, and Australasia. We applied the Montreal classification system of inflammatory bowel disease subphenotypes to 34,819 patients (19,713 with Crohn's disease, 14,683 with ulcerative colitis) genotyped on the Immunochip array. We tested for genotype...

    Cytomegalovirus (CMV) colitis is uncommon in immunocompetent patients, despite a high seroprevalence rate of CMV in the general population. CMV infection has been described in individuals with compromised immune systems: in AIDS, under corticosteroid and immune modulating treatment, with cancer or haematological malignancies. Its most frequent clinical presentation is a necrotising ulcerative form; pseudotumoural CMV colitis has been described as highly exceptional. We report a case of CMV colitis mimicking rectal carcinoma in an immunocompetent elderly woman. The immunosenescence and protein-energy malnutrition increase incidence and severity of infectious diseases in elderly individuals. Immunosenescence may affect all aspects of immunity; severe protein malnutrition modifies mostly cellular immunity, growing susceptibility to infections. PMID:27166009

    @@ TO THE EDITOR With great interest we read the recent retrospectice study by Barta et al (1) dealing with the clinical presentation of patients with microscopic colitis. They investigated in a cohort of 53 patients with microscopic colitis (46 with collagenous colitis, 7 with lymphocytic colitis)the relationship between microscopic colitis and both constipation and diarrhea. One of their mean finding was that abdominal pain, diarrhea and constipation was a common symptom complex of patients with microscopic colitis, thus the face of microcopic colitis resembles the subgroups of irritable bowel syndrome (IBS).

    Interleukin-10 (IL-10)-deficient mice spontaneously develop T cell-mediated colitis. Previous reports have shown that Matrine may reduce the symptoms of acute colitis induced by trinitrobenzene sulfonic acid (TNBS). However, whether Matrine impacts chronic colitis remains unknown. In this study, we investigated whether Matrine could limit the symptoms of spontaneously developed colitis and its potential molecular mechanisms. IL-10 deficient mice were given Matrine or a PBS control by oral gavage daily for 4weeks and were euthanized at week 2 or week 4. We measured body weight, colon length and weight, and histological scores. We also evaluated the spontaneous secretion of IL-12/23p40, IFN-γ and IL-17 in colon explant cultures as well as IFN-γ and IL-17 secretion in unseparated mesenteric lymph node (MLN) cells, and assessed IFN-γ, IL-17, IL-1β and IL-6 mRNA expression in colon tissue. In addition, we analyzed the proportions of CD4-positive and CD8-positive cells in unseparated MLN cells. Our results show that Matrine-treated mice exhibited better body weight recovery than controls and that histological scores and spontaneously secreted IL-12/23p40, IFN-γ and IL-17 in colon tissue were significantly decreased in treated mice compared with controls. The proportion of CD4-positive cells of MLNs in treated mice was significantly smaller than that in controls at week 4. Both cytokine production and mRNA expression of IFN-γ and IL-17 were significantly reduced in treated mice compared with controls. Taken together, our results indicate that Matrine may ameliorate spontaneously developed chronic colitis and could be considered as a therapeutic alternative for chronic colitis. PMID:27179305

    The renin-angiotensin system (RAS) plays pathogenic roles in renal and cardiovascular disorders, but whether it is involved in colitis is unclear. Here we show that RenTgMK mice that overexpress active renin from the liver developed more severe colitis than wild-type controls. More than 50% RenTgMK mice died whereas all wild-type mice recovered. RenTgMK mice exhibited more robust mucosal TH17 and TH1/TH17 responses and more profound colonic epithelial cell apoptosis compared to wild-type cont...

    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.

Vesicular lesions with red haloes ranged from the left side of her buttock to the left extremity, corresponding to the L4 to S2 dermatomes. Her colitis was considered to have been induced by varicella-zoster virus, based on the facts that the clinical courses were correlated and that the innervation of the affected site of the colon corresponded to an infected dermatome (S2).

    Colorectal Kaposi's sarcoma, a human herpes virus-8 associated mesenchymal tumour, is exceedingly rare in human immunodeficiency virus-negative subjects and almost always reported in association with severe, refractory, inflammatory bowel disease. In this paper we report a case--the second from Italy--of a colorectal Kaposi's sarcoma in a human immunodeficiency virus-negative, heterosexual man with severe refractory ulcerative colitis. Kaposi's sarcoma developed after starting glucocorticosteroid therapy, supporting the theory that colorectal Kaposi's sarcoma associated with ulcerative colitis is iatrogenic. PMID:18054849

    The Neutrophilic dermatosis (ND) is considered as an independent entity with diverse clinical manifestations among which there are: gangrenous pyoderma, nodous erythema, Sweets Syndrome, vesiculopustula eruptions associated to ulcerous colitis and intestinal short circuit syndrome with or without short circuit. Histologically, they are characterized by infiltration of polymorphonuclear neutrophils, generally at the dermic level, but also at the epidermic. They are usually associated to systemic diseases, especially to chronic intestinal inflammatory disease. Our aim was to describe two forms of clinical presentation of neutrophilic dermatosis: gangrenous pyoderma and vesiculopustula eruption, associated to ulcerous colitis starting at advances ages.

    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

    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.

  6. Development of a pulse height analizer

    International Nuclear Information System (INIS)

    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)

  8. Anal incontinence: diagnosis by endoanal US or endovaginal MRI

    International Nuclear Information System (INIS)

    Preoperative evaluation was made of the diagnostic value of endoanal ultrasound (EAUS) and endovaginal magnetic resonance imaging (EVMRI) in diagnosing anal sphincter defects as the cause of anal incontinence. Nineteen female individuals with anal incontinence were examined clinically with EAUS and with EVMRI at 1.5 T using a prostatic coil. The findings were evaluated independently and compared with findings at surgery. In diagnosing external anal sphincter defects, EAUS and EVMRI showed almost similar agreement with surgical findings, 12 (63%) out of 19 vs 11 (58%), respectively. Internal anal sphincter defects were equally detected by EAUS and EVMRI as compared with surgical diagnosis. There was considerable variation between radiologists in diagnosing defects by EVMRI. EAUS and EVMRI are equal in diagnosing anal sphincter defects. (orig.)

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.

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

    2016-01-01

    Anal health and anal cancer are rarely addressed in HIV primary care. We sought to understand factors that impeded or promoted addressing anal health in HIV primary care from providers' perspectives. In this exploratory study, HIV primary care providers from the Mid-South region of the United States participated in brief individual interviews. We analyzed transcribed data to identify barriers and facilitators to addressing anal health. Our study sample included five physicians and four nurse practitioners. The data revealed a number of barriers such as perception of patient embarrassment, provider embarrassment, external issues such as time constraints, demand of other priorities, lack of anal complaints, lack of resources, and gender discordance. Facilitators included awareness, advantageous circumstances, and the patient-provider relationship. Anal health education should be prioritized for HIV primary care providers. Preventive health visits should be considered to mitigate time constraints, demands for other priorities, and unequal gender opportunities. PMID:27080925

    The physiological balance between pro- and anti-inflammatory processes is dysregulated in inflammatory bowel diseases (IBD) as in Crohn's disease and ulcerative colitis. Conventional therapy uses anti-inflammatory and immunosuppressive corticosteroids to treat acute-phase symptoms. However, low remission rate and strong side effects of these therapies are not satisfying. Thus, there is a high medical need for new therapeutic strategies. Soluble CD83, the extracellular domain of the transmembrane CD83 molecule, has been reported to have interesting therapeutic and immunosuppressive properties by suppressing dendritic cell (DC)-mediated T-cell activation and inducing tolerogenic DCs. However, the expression and function of CD83 in IBD is still unknown. Here, we show that CD83 expression is upregulated by different leukocyte populations in a chemical-induced murine colitis model. Furthermore, in this study the potential of sCD83 to modulate colitis using an experimental murine colitis model was investigated. Strikingly, sCD83 ameliorated the clinical disease symptoms, drastically reduced mortality, and strongly decreased inflammatory cytokine expression in mesenteric lymph nodes and colon. The infiltration of macrophages and granulocytes into colonic tissues was vigorously inhibited. Mechanistically, we could show that sCD83-induced expression of indolamine 2,3-dioxygenase is essential for its protective effects. PMID:24424524

    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.

    AIM:To characterize the influence of diet-induced changes in body fat on colitis severity in SMAD3-/-mice.METHODS:SMAD3-/-mice (6-8 wk of age) were randomly assigned to receive a calorie restricted (30%of control; CR),control (CON),or high fat (HF) diet for 20 wk and were gavaged with sterile broth or with Helicobacter hepaticus (H.hepaticus) to induce colitis.Four weeks after infection,mice were sacrificed and the cecum and colons were processed for histological evaluation.RESULTS:Dietary treatment significantly influenced body composition prior to infection (P < 0.05),with CR mice having less (14% ± 2%) and HF-fed mice more body fat (32% ± 7%) compared to controls (22% ±4%).Differences in body composition were associated with alterations in plasma levels of leptin (HF > CON > CR) and adiponectin (CON > HF ≥ CR) (P < 0.05).There were no significant differences in colitis scores between CON and HF-fed mice 4 wk post-infection.Consistent with this,differences in proliferation and inflammation markers (COX-2,iNOS),and infiltrating cell types (CD3+ T lymphocytes,macrophages) were not observed.Unexpectedly,only 40% of CR mice survived infection with H.hepaticus,with mortality observed as early as 1 wk following induction of colitis.CONCLUSION:Increased adiposity does not influence colitis severity in SMAD3-/-mice.Importantly,caloric restriction negatively impacts survival following pathogen challenge,potentially due to an impaired immune response.

  12. Altered response to hydrogen sulphide during experimental colitis in rats.

    Hydrogen sulphide (H(2) S) is produced in the intestine by sulphate-reducing bacteria and during metabolism of L-cysteine within the mucosa. This gasotransmitter induces anion secretion by stimulating enteric neurons and by a direct effect on epithelial cells. As H(2) S is discussed to exert both pro- and anti-inflammatory actions, we aimed to investigate the role of H(2) S during experimental colitis by comparing the effects of blockade of H(2) S-forming endogenous enzymes with the effect of a S-reduced diet to diminish microbial production of H(2) S. Rectal application of trinitrobenzenesulfonic acid (TNBS) was used to induce chronic colitis. The level of inflammation was assessed macroscopically and histologically. In Ussing chamber experiments, colonic specimens from TNBS-treated animals exhibited a higher tissue conductance, that is, a higher epithelial permeability, and a slightly reduced basal short-circuit current (a measure of net ion transport) in relation to non-inflamed control tissue. Analgetic treatment with flupirtine, a central antinociceptive analgetic, did not interfere with the induction of the inflammatory response so that all animals were treated with flupirtine to reduce pain and distress during the development of colitis. The secretory response evoked by an exogenous H(2) S donor, NaHS, was significantly decreased after induction of colitis, whereas the response to Ca(2+) - or cAMP-dependent secretagogues was unaltered. This downregulation was not observed in the colitis group fed on a S-reduced diet. The decreased NaHS response indicates a desensitization of the tissue by inflammation, which might be explained by an upregulation of colonic H(2) S production as described in some models of inflammation.

  13. Macrophage expression in acute radiation colitis in rats

    International Nuclear Information System (INIS)

    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.

  18. Anal cancer and intraepithelial neoplasia screening: A review.

    Science.gov (United States)

    Leeds, Ira L; Fang, Sandy H

    2016-01-27

    This review focuses on the early diagnosis of anal cancer and its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.

  3. Anal canal carcinoma: Diagnosis - therapy - prognosis

    International Nuclear Information System (INIS)

    78 patients with anal canal carcinoma were treated between 1970 and 1988 at the University Hospital Erlangen. 48 patients (35 women, 13 men) were treated by surgery alone, 44/48 by abdominoperineal resection, 4/48 by local excision. Median age was 63 years, median follow-up 8.5 years. The overall local recurrence rate was 16.7%, the overall five-year-survival was 51%. 30 patients received a combined radio-chemotherapy. The small pelvis was treated with a.-p./p.-a. fields up to a total dose between 42 and 50 Gy. Two courses of chemotherapy consisting of 5-FU (800 to 1000 mg/m2 days 1 to 4 and 29 to 32) and Mitomycin C (10 mg/m2 days 1 and 29) were administered. Two months after completion of treatment 83% had a biopsy proven complete remission. After a median follow-up of 15 months 87% are alive with NED, 74% are continent. The combined regimen of radio-chemotherapy is considered as the treatment of the choice for anal canal carcinoma. Abdominoperineal resection is only performed in patients with non response or local recurrent disease. (orig.)

  4. Conservative management of anal and rectal cancer

    International Nuclear Information System (INIS)

    The role of irradiation in the management of anal and rectal cancer has changed during the past ten years. In small epidermoid carcinomas of the anal canal (T1 T2) irradiation is in most departments considered the primary treatment, giving a 5-year survival rate of between 60 and 80% with good sphincter preservation. Even in larger tumors, irradiation can still offer some chance of cure without colostomy. Surgery remains the basic treatment of rectal cancer but irradiation is used in association with surgery in many cases. Radiotherapy is of value in the conservative management of cancer of the rectum in three situations: In small polypoid cancers contact X-ray therapy can give local control in about 90%. In cancers of the middle rectum, preoperative external irradiation may increase the chances of restorative surgery and reduce the risk of local relapse. In inoperable patients, external radiotherapy and/or intracavitary irradiation may cure some patients with infiltrating tumors (T2 T3) without colostomy. (orig.)

    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.

    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

    2008-01-01

    AIM: To investigate the prevalence and demography of microscopic colitis in patients with diarrhea of unknown etiology and normal colonoscopy in Turkey. METHODS: Between March, 1998 to July, 2005, 129 patients with chronic non-bloody diarrhea of unexplained etiology who had undergone full colonoscopy with no obvious abnormalities were included in the study. Two biopsies were obtained from all colonic segments and terminal ileum for diagnosis of microscopic colitis. On histopathologic examination, criteria for lymphocytic colitis (intraepithelial lymphocyte ≥ 20 per 100 intercryptal epithelial cells, change in surface epithelium, mononuclear infiltration of the lamina propria) and collagenous colitis (subepithelial collagen band thickness ≥ 10 μm) were explored. RESULTS: Lymphocytic colitis was diagnosed in 12 (9%) patients (Female/Male: 7/5, mean age: 45 year, range: 27-63) and collagenous colitis was diagnosed in only 3 (2.5%) patients (all female, mean age: 60 years, range: 54-65). CONCLUSION: Biopsy of Turkish patients with the diagnosis of chronic non-bloody diarrhea of unexplained etiology and normal colonoscopic findings will reveal microscopic colitis in approximately 10% of the patients. Lymphocytic colitis is 4 times more frequent than collagenous colitis in these patients

    Chronic Granulomatous Disease (CGD) is an inherited primary immunodeficiency disease which increases the body's susceptibility to infections caused by certain bacteria and fungi. CGD is a rare disease, caused by four genes, one type is 1X linked and the other three are "autosomal recessive". Although clinical presentation is variable, but characteristic features are recurrent pneumonia, lymphadenitis, hepatic or other abscesses. Gastrointestinal tract symptoms are common in x-linked recessive form of CGD. These include gastric and esophageal obstruction and inflammatory bowel disease. GI involvement including small and large intestines, the findings of luminal narrowing and the presence of granuloma can make it difficult to distinguish from Crohn's disease. On the other hands according to the literature ulcerative colitis is rarely reported in patients with CGD. Our case presented with ulcerative colitis with CGD. PMID:26328046

    AIM: To determine the prevalence of increased in-traepithelial lymphocytes, using immunohistochemistry in patients with normal colonoscopy and near normal biopsy. METHODS: We retrospectively reviewed all non-malig-nant colon mucosal biopsies between 2005 and 2007, reported as normal, chronic inflammation or melanosis coli in patients who were undergoing routine colonos-copy. Immunohistochemistry using CD3 was performed on all mucosal biopsies and an intraepithelial lympho-cyte count (IEL) was determined. Cases with an IEL count of ≥ 20 IELs per 100 surface epithelial cells were correlated with demographic, clinical and follow-up data. A further subgroup was evaluated for lymphocytic colitis.RESULTS: Twenty (8.3%) of 241 cases revealed an IEL count ≥ 20. Six (2.5%) patients were identified as having lymphocytic colitis (P < 0.001), of whom, five were missed on initial evaluation (P = 0.01). Four of these five patients were labeled with diarrhea-predom-inant irritable bowel syndrome (IBS). On follow-up, three of the remaining 20 cases were diagnosed with malignancy (renal cell carcinoma and myelodysplastic syndrome) and one had an unknown primary tumor with multiple liver metastases. Two cases of collag-enous colitis with an IEL count < 10 were included in this study. Increased IELs were not confined to pa-tients with diarrhea as a primary presenting symptom, but were also present in patients with abdominal pain (n = 7), constipation (n = 3) and loss of weight (n = 1). CONCLUSION: Immunohistochemistry using CD3 is of value in identifying and quantifying IELs for the pres-ence of microscopic colitis in patients with diarrhea-predominant IBS.

    Full Text Available Background: Free radicals are the known mechanisms responsible for inducing colitis with two origins: Inflammatory cells and tissues. Only the inflammatory cells can be controlled by corticosteroids. Our aim was to assess the importance of neutrophils as one of the inflammatory cells in inducing colitis and to evaluate the efficacy of corticosteroids in the treatment of inflammatory bowel disease (IBD. Materials and Methods: Thirty-six mice were divided into six groups of six mice each. Colitis was induced in three groups by exposing them to acetic acid through enema (group 1, ex vivo (group 3, and enema after immune suppression (group 5. Each group had one control group that was exposed to water injection instead of acetic acid. Tissue samples were evaluated and compared based on macroscopic damages and biochemical and pathological results. Results: Considering neutrophilic infiltration, there were significant differences between groups 1, 3, 5, and the control of group 1. Groups 3, 5, and their controls, and group 1 and the control of group 3 had significant differences in terms of goblet depletion. Based on tissue originated H 2 O 2 , we found significant differences between group 1 and its control and group 3, and also between groups 5 and the control of group 3. All the three groups were significantly different from their controls based on Ferric Reducing Ability of Plasma (FRAP and such differences were also seen between group 1 with two other groups. Conclusion: Neutrophils may not be the only cause of oxidation process in colitis, and also makes the effectiveness of corticosteroids in the treatment of this disease doubtful.

    Ulcerative colitis (UC) is a chronic inflammatory bowel disease limited to the mucosa and affecting the rectum and the colon continuously. Salicylates are the first line treatment for moderate forms. Corticosteroids are used to induce remission, but are not given as maintenance therapy. Thiopurines are indicated as maintenance therapy in case of failure of salicylates or cortico-dependence. Anti TNF alpha are indicated in cortico-resistant severe flares or if cortico- dependence. Vedolizumab (anti-integrin) is the first non anti-TNF alpha biotherapy available for the treatment of UC. Severe acute colitis is a medical emergency; diagnosis is based on Lichtiger score. An emergency colectomy for severe acute colitis is indicated in cases of surgical complication or resistance to medical therapy. UC patients with extension beyond splenic flexure are at risk of colorectal cancer, increasing with the duration of the disease, severity of mucosal inflammation, family history of colorectal cancer, and the existence of sclerosing cholangitis. Annual surveillance colonoscopy is required in patients with sclerosing cholangitis regardless of the extension of their UC. PMID:25534469

    The mucosa of the esophagus, the stomach, the small intestine, the large intestine and rectum are unremittingly challenged by adverse micro-environmental factors, such as ingested pathogenic and non-pathogenic bacteria, and harsh secretions with digestive properties with disparate pH, as well as bacteria and secretions from upstream GI organs. Despite the apparently inauspicious mixture of secretions and bacteria, the normal GI mucosa retains a healthy state of cell renewal. To by-pass the tough microenvironment, the epithelia of the GI react by speeding-up cell exfoliation, by increasing peristalsis, eliminating bacteria through secretion of plasma cell-immunoglobulins and by increasing production of natural antibacterial enzymes (lysozyme) and host defense peptides (defensin-5). Lysozyme was recently found up-regulated in Barrett's esophagitis, in chronic gastritis, in gluten-induced atrophic duodenitis (celiac disease), in collagenous colitis, in lymphocytic colitis and in Crohn's colitis. This up-regulation is a response directed towards the special types of bacteria thriving in the microenvironment in each of the aforementioned clinical inflammatory maladies. The purpose of that up-regulation is to protect the mucosa affected by the ongoing chronic inflammation. Bacterial antibiotic resistance continues to exhaust our supply of effective antibiotics. The future challenge is how to solve the increasing menace of bacterial resistance to anti-bacterial drugs. Further research on natural anti-bacterial enzymes such as lysozyme, appears mandatory.

    Full Text Available 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-1β, 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-1β and IL-6 production. LJE and probiotics demonstrated a synergistic effect by the histological score and levels of IL-1β, 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.

    Although anal squamous cell carcinoma (ASCC) is an uncommon malignancy, its incidence has been increasing markedly in recent decades due to its association with human papilloma virus (HPV) infection. The well-established standard of care for localized ASCC consists of the combination of 5-fluorouracil (5FU) and mitomycin (MMC) chemotherapy, concurrent with external beam radiation therapy (EBRT). However, newer techniques are being actively pursued, including the use of newer radiation therapy (RT) technologies, such as intensity-modulated radiation therapy (IMRT). The areas of debate and development include the dosing and timing of MMC delivery, the role of cisplatin chemotherapy as an alternative to MMC, the replacement of the standard 96-h infusion of 5FU with oral capecitabine, the use of targeted chemotherapy agents, and the duration and dose of RT.

    Full Text Available BACKGROUND: The tetracyclic triterpene euphol is the main constituent found in the sap of Euphorbia tirucalli. This plant is widely known in Brazilian traditional medicine for its use in the treatment of several kinds of cancer, including leukaemia, prostate and breast cancers. Here, we investigated the effect of euphol on experimental models of colitis and the underlying mechanisms involved in its action. METHODOLOGY/PRINCIPAL FINDINGS: Colitis was induced in mice either with dextran sulfate sodium (DSS or with 2,4,6-trinitrobenzene sulfonic acid (TNBS, and the effect of euphol (3, 10 and 30 mg/kg on colonic injury was assessed. Pro-inflammatory mediators and cytokines were measured by immunohistochemistry, enzyme-Linked immunoabsorbent assay (ELISA, real time-polymerase chain reaction (RT-PCR and flow cytometry. Preventive and therapeutic oral administration of euphol attenuated both DSS- and TNBS-induced acute colitis as observed by a significant reduction of the disease activity index (DAI, histological/microscopic damage score and myeloperoxidase (MPO activity in colonic tissue. Likewise, euphol treatment also inhibited colon tissue levels and expression of IL-1β, CXCL1/KC, MCP-1, MIP-2, TNF-α and IL-6, while reducing NOS2, VEGF and Ki67 expression in colonic tissue. This action seems to be likely associated with inhibition of activation of nuclear factor-κB (NF-κB. In addition, euphol decreased LPS-induced MCP-1, TNF-α, IL-6 and IFN-γ, but increased IL-10 secretion from bone marrow-derived macrophages in vitro. Of note, euphol, at the same schedule of treatment, markedly inhibited both selectin (P- and E-selectin and integrin (ICAM-1, VCAM-1 and LFA-1 expression in colonic tissue. CONCLUSIONS/SIGNIFICANCE: Together, these results clearly demonstrated that orally-administered euphol, both preventive or therapeutic treatment were effective in reducing the severity of colitis in two models of chemically-induced mouse colitis and suggest

  6. Radiotherapy of the anal canal cancer

    International Nuclear Information System (INIS)

    From 1976 to 1987, 58 patients presenting an anal canal epidermoid carcinoma underwent radiation therapy alone as primary treatment. There were 48 females and ten males with a mean age of 65 years ± 15.5. Tumors were staged according to the 1979 UICC-TNM classification. There were six T1 (10%), 15 T2 (26%), 28 T3 (48%) and nine T4 (16%). Inguinal lymph nodes were involved in 17 cases (29%). No chemotherapy was given. Forty one patients without node involvement were irradiated according to the Papillon Technique. Twenty seven of these patients were boosted with brachytherapy and eight through a perineal portal with a cobalt unit or an electron beam so that the mean cumulative dose to the tumor 55 Gy. Six patients had radical surgery after a poor response to initial radiation therapy. Patients with inguinal involvement were treated by a three or four fields technique with a high energy photons beam (X 25 MV). The given dose to the tumor was between 60-65 Gy in 6.5 weeks. Surgery was performed in two patients with poor regression of the tumor after initial radiotherapy. Mean follow up was 7 years. Forty nine patients (84.4%) were locally controlled. Four failures were salvaged by surgery. Twenty four patients died from cancer and the overall actuarial 3 years and 5 years survival rate were 67% and 50% respectively. Severe side effect of radiation therapy occurred in 5% of cases. Anal sphincter function was preserved in 69% of the patients. This study confirms that radiation therapy gives results comparable with those of surgery allowing the patients to avoid anorectal resection. (author). 22 refs

    AIM Autoimmunity has been emphasized in the pathogenesis of ulcerative colitis (UC). We reported thattropomyosin (TM) or TM related protein is a putative autoantigen in UC. In human fibroblast, at least 8isoforms of TM have been identified with molecular weight range from 30kD to 40kD, depending upon theisoforms, and human TM isoforms (hTM5) has been found the main isoform in human intestinal epithelialcells. In this study, hTM5 was used as a putative auto-antigen for the humoral and T cell immune responses inpatients with UC, Crohn's disease (CD) and healthy subjects (HS) as controls.METHODS Anti-bTM antibody was examined by enzyme-linked immunosorbent assay using human sera(UC 59, CD 28, HS 26) against hTM isoforms. The IFN-γ production by peripheral blood T cells followingstimulation by recombinant hTM5 was analyzed by ELISPOT assay.RESULTS Anti-hTM5 antibody (IgG1) was detected in 15/59 (25.4%) patients with UC, 3/28 (10.γ%)with CD, and 3/26 (11.5%) of HS. The OD value in UC was significantly higher than in CD and HS groups(P < 0.05; P < 0.01 respectively). Western blot analysis demonstrated immunoreactivity against hTM5 inseveral UC sera. ELISPOT assay demonstrated that IFN-γ production is significantly higher in UC (7/18),39.0%), compared with CD (0/8, 0%) and HS (0/7, 0%), (P<0.05).CONCLUSION A significantly higher immune response to hTM5 was present in UC compared to CD andHS. Further studies of the hTM5/peptides may provide immuno-biochemical mechanism of autoimmuneprocess in UC.

    Full Text Available Objectives 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. Methods 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. Results 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.

    2012-03-01

    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.

    2016-01-01

    Full Text Available Obestatin, a 23-amino acid peptide derived from the proghrelin, has been shown to exhibit some protective and therapeutic effects in the gut. The aim of present study was to determine the effect of obestatin administration on the course of acetic acid-induced colitis in rats. Materials and Methods. Studies have been performed on male Wistar rats. Colitis was induced by a rectal enema with 3.5% acetic acid solution. Obestatin was administered intraperitoneally twice a day at a dose of 8 nmol/kg, starting 24 h after the induction of colitis. Seven or 14 days after the induction of colitis, the healing rate of the colon was evaluated. Results. Treatment with obestatin after induction of colitis accelerated the healing of colonic wall damage and this effect was associated with a decrease in the colitis-evoked increase in mucosal activity of myeloperoxidase and content of interleukin-1β. Moreover, obestatin administration significantly reversed the colitis-evoked decrease in mucosal blood flow and DNA synthesis. Conclusion. Administration of exogenous obestatin exhibits therapeutic effects in the course of acetic acid-induced colitis and this effect is related, at least in part, to the obestatin-evoked anti-inflammatory effect, an improvement of local blood flow, and an increase in cell proliferation in colonic mucosa.

  18. Differential Acute Effects of Selenomethionine and Sodium Selenite on the Severity of Colitis

    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.

    Full Text Available Management of anal cancer is a challenge. The goal of treatment is to eradicate tumor without sacrificing the anal sphincters. The idea of organ preservation emerged following the discovery of a high complete response rate from preoperative combined chemoradiation (CRT prior to abdominoperineal resection.CRT is widely accepted as the standard therapy for treating anal squamous cell cancer. The combination of external beam radiotherapy with interstitial brachytherapy increases the dose to the tumor volume and decreases dose to normal tissues. The current goal is to avoid colostomy, and surgery has become a salvage or secondary therapy. In this article, we review the non-surgical management of anal cancer with special emphasis on CRT, role of intensity modulated radiation therapy and brachytherapy.

    2006-01-01

    Tumors arising from the anal canal are usually of epithelial origin and are mostly squamous cell carcinoma or basal cell carcinoma. We present a case of benign anal adenomas arising from the anus, an extremely rare diagnosis. A 78-year-old white man presented with rectal bleeding of several months duration. Examination revealed a 4 cm friable mass attached to the anus by a stalk. At surgery, the mass was grasped with a Babcock forceps and was resected using electrocautery.Microscopic examination revealed a tubulovillus adenoma with no areas of high grade dysplasia or malignant transformation. The squamocolumnar junction was visible at the edges of the lesion confirming the anal origin of the tumor. We believe the tubulovillus adenoma arose from either an anal gland or its duct that opens into the anus. Although seen rarely, it is important to recognize and treat these tumors at an early stage because of their potential to transform into adenocarcinoma.

    2012-03-01

    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.

    2010-10-01

    Full Text Available Abstract Infection with human papillomavirus (HPV is a major risk factor for development of anal squamous cell carcinoma. Despite over 100 genotypes of the virus, HPV 16 and 18 are considered pathogenic as they are seen in the majority of cervical and anal cancers. We have employed a custom microarray to examine DNA for several HPV genotypes. We aimed to determine the accuracy of our microarray in anal cancer DNA for HPV genotypes compared to the DNA sequencing gold standard. Methods We utilized a sensitive microarray platform to classify 37 types of mucosal HPVs including 14 known high-risk and 23 low-risk types based on cervical cancer data. We utilized DNA from pathologically confirmed cases of anal squamous cell carcinoma. All samples underwent microarray HPV genotyping and PCR analysis. Results HPV was detected in 18/20 (90% anal cancers. HPV genotypes 16 and 18 were present in the majority of specimens, with HPV 16 being the most common. Eighty percent of anal cancers had at least two HPV types. Ten percent of cases (2/20 tested negative using our microarray; DNA sequencing confirmed the lack of presence of HPV DNA in these samples. Conclusions Microarray technology is an accurate way to screen for various genotypes of HPV in anal cancer, with 100% correlation with genomic DNA detection of HPV. The majority of anal cancers in our study associated with pathogenic HPV 16 and/or 18. Other HPV genotypes are present simultaneously with HPV 16 and 18, and might contribute to its pathogenesis.

    Premalignant and malignant lesions of the anal margin are rare. Understanding anal anatomy and performing a biopsy of any suspicious lesions are essential in avoiding a delay in diagnosis and appropriately treating these tumors. Wide local excision continues to remain the treatment of choice for many of these lesions. Combined multimodality treatment has come to play an important role in managing patient with more advanced or metastatic disease.

    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. PMID:19436763

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.

    There is no consensus on optimal screening for anal cancer (AC) in HIV+ women. Seven hundred fifteen unique asymptomatic women in a high-prevalence HIV+ community were screened for AC with anal cytology and triage to high-resolution anoscopy after routine screening was implemented in a large urban hospital system. Of these, 75 (10.5%) had an abnormal anal cytology and 29 (38.7%) of those with an abnormality had high-grade anal intraepithelial neoplasia (AIN). Women with poorly controlled HIV were significantly more likely to have high-grade AIN (P = 0.03). Given the high rate of AIN in screened HIV-infected women, routine AC screening in all HIV-infected women should be strongly considered. PMID:22466085

    Inflammatory bowel disease (IBD) presents intense inflammatory infiltrate, crypt abscesses, ulceration and even loss of function. Despite the clinical relevance of IBD, its current therapy remains poorly effective. Infrared wavelength phototherapy shows therapeutic potential on inflammation. Our goal was to evaluate whether light-emitting diodes (LED) at 940nm are capable of mitigating the colitis-induced inflammatory process in mice. Forty male Swiss mice were assigned into five groups: control; control treated with LED therapy; colitis without treatment; colitis treated with LED therapy; colitis treated with Prednisolone. Experimental colitis was induced by acetic acid 7.5% (pH2.5) rectal administration. LED therapy was performed with light characterized by wavelength of 940nm, 45nm bandwidth, intensity of 4.05J/cm(2), total power of 270mW and total dose of 64.8J for 4min in a single application. Colitis-induced intestinal transit delay was inhibited by LED therapy. Colitis caused an increase of colon dimensions (length, diameter, total area) and colon weight (edema), which were inhibited by LED therapy. LED therapy also decreased colitis-induced tissue gross lesion, myeloperoxidase activity, microscopic tissue damage score and the presence of inflammatory infiltrate in all intestinal layers. Furthermore, LED therapy inhibited colitis-induced IL-1β, TNF-α, and IL-6 production. We conclude LED therapy at 940nm inhibited experimental colitis-induced colon inflammation in mice, therefore, rendering it a promising therapeutic approach that deserves further investigation.

    1985-04-15

    A generalized debilitating disease in a horse was believed to be related to hypersensitivity to migrating strongyle larvae. The clinical signs included weight loss, diarrhea, and ulcers on all 4 coronary bands. The mare's condition deteriorated rapidly, so the mare was euthanatized and necropsied. The major histopathologic findings were chronic multifocal eosinophilic pancreatitis, hepatic portal fibrosis, biliary hyperplasia, and chronic ulcerative eosinophilic colitis. This case was similar to previously reported cases of chronic eosinophilic gastroenteritis in horses. Although the etiologic agent was not evident, the distribution and character of the lesions were consistent with a hypersensitivity response to migrating parasitic larvae, most probably Strongylus equinus.

    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

    Abnormalities of lipid metabolism through overexpression of fatty acid synthase (FASN), which catalyzes the formation of long-chain fatty acids, are associated with the development of inflammatory bowel disease (IBD). C75 is a synthetic α-methylene-γ-butyrolactone compound that inhibits FASN activity. We hypothesized that C75 treatment could effectively reduce the severity of experimental colitis. Male C57BL/6 mice were fed 4% dextran sodium sulfate (DSS) for 7 d. C75 (5 mg/kg body weight) or...

    Anal squamous cell cancer is an uncommon malignancy caused by infection with oncogenic strains of Human papilloma virus. Anal cancer is much more common in immunocompromised persons, including those infected with Human immunodeficiency virus. High-grade anal intraepithelial neoplasia (HGAIN), the precursor of anal cancer, is identified by clinicians providing care for patients with anorectal disease, and is increasingly being identified during screening of immunosuppressed patients for anal dysplasia. The traditional treatment for HGAIN has been excision of macroscopic disease with margins. This approach is effective for patients with small unifocal HGAIN lesions. Patients with extensive multifocal HGAIN frequently have recurrence of HGAIN after excision, and may have postoperative complications of anal stenosis or fecal incontinence. This led to the suggestion by some that treatment for HGAIN should be delayed until patients developed anal cancer. Alternative approaches in identification and treatment have been developed to treat patients with multifocal or extensive HGAIN lesions. High-resolution anoscopy combines magnification with anoscopy and is being used to identify HGAIN and determine treatment margins. HGAIN can then be ablated with a number of modalities, including infrared coagulation, CO2 laser, and electrocautery. These methods for HGAIN ablation can be performed with local anesthesia on outpatients and are relatively well tolerated. High-resolution anoscopy-directed HGAIN ablation is evolving into a standard approach for initial treatment and then subsequent monitoring of a disease which should be expected to be recurrent. Another treatment approach for HGAIN is topical treatment, principally with 5-fluorouracil or imiquimod. Topical therapies have the advantage of being nonsurgical and are well suited for treating widespread multifocal disease. Topical treatments have the disadvantage of requiring extended treatment courses and causing a symptomatic

    Full Text Available Objective: to evaluate the effectiveness of endoanal ultrasound with hydrogen peroxide enhancement in the assessment of anal fistula (tract and internal opening, and to value the utility of this examination for anal or perianal suppuration when performed by a colorectal surgeon trained in this technique. Patients: endoanal ultrasound was performed in 103 patients with anal or perianal suppuration. Twenty patients were excluded: 9 had the external opening closed, and 11 had cryptoglandular abscesses. All ultrasound scans were performed by the same explorer using a B&K Diagnostic Ultrasound System with a 7 MHz endoprobe. The examination was based on the identification of the three anal planes, then hydrogen peroxide was infused and the procedure was repeated. Results: out of 83 patients included, 11 had a perianal sinus and 72 an anal fistula. In all fistulas the main tract was found: 24 were inter-sphinteric (33.33%, 33 trans-sphincteric (45.83%, 3 supra-sphincteric (4.17%, and 12 extra-sphincteric (16.67%. An internal opening was identified in 69 (95.83%. Conclusions: endoanal ultrasound with hydrogen peroxide enhancement is an effective examination to visualize fistulous tracts and internal openings. We think it is highly useful for anal or perianal suppuration to identify abscesses, to recognize a perianal sinus, to check the sphincteric condition, and to plan subsequent surgery.Objetivo: evaluar la efectividad de la ecografía endoanal contrastada con inyección de agua oxigenada para establecer la topografía fistulosa (trayecto y localización del orificio interno y valorar la conveniencia de esta exploración en la supuración anal o perianal cuando es realizada por un cirujano general dedicado a coloproctología y entrenado en esta técnica.

    AIM: To investigate the roles of lymphocytes in the development of dextran sulfate sodium-induced colitis.METHODS: Using various doses of dextran sulfate sodium (DSS), we induced colitis in wild-type B6control and Rag-1 knockout (H-2b haplotype) mice,and evaluated the colitis in terms of symptomatic and histologic parameters, such as weight loss, survival,severity of diarrhea, shortage of colon length and histological changes. Symptomatic parameters were checked daily and histological changes were scored.RESULTS: Although development of colitis in Rag-1knockout mice treated with high dose (5%) of DSS was comparable to that in B6 control mice, colitis progression was much more tolerable in Rag-1 knockout mice compared to than in B6 mice treated with low dose (1.5%)DSS. Symptomatic parameters as well as histopathologic changes were improved in Rag-1 knockout mice.CONCLUSION: These results indicate that the presence of lymphocytes contributes to colitis progression at low dose of DSS stimulation. Lymphocytes may play roles as an aggravating factor in DSS-induced colitis.

    Previous studies have shown that ghrelin reduces colonic inflammation induced by trinitrobenzene sulfonic acid and dextran sodium sulfate. In the present study we determined the effect of treatment with ghrelin on the course of acetic acid-induced colitis in rats. Rectal administration of 3% acetic acid solution led to induction of colitis in all animals. Damage of the colonic wall was accompanied by an increase in mucosal concentration of pro-inflammatory interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α), as well mucosal activity of myeloperoxidase. Moreover, induction of colitis led to a reduction in colonic blood flow and DNA synthesis. Administration of ghrelin after induction of colitis led to faster regeneration of the colonic wall and reduction in colonic levels of IL-1β, TNF-α, and myeloperoxidase. In addition, treatment with ghrelin improved mucosal DNA synthesis and blood flow. Our study disclosed that ghrelin exhibits a strong anti-inflammatory and healing effect in acetic acid-induced colitis. Our current observation in association with previous findings that ghrelin exhibits curative effect in trinitrobenzene sulfonic acid- and dextran sodium sulfate-induced colitis suggest that therapeutic effect of ghrelin in the colon is universal and independent of the primary cause of colitis.

  11. Salmon cartilage proteoglycan suppresses mouse experimental colitis through induction of Foxp3+ regulatory T cells

    International Nuclear Information System (INIS)

    Research highlights: → Salmon proteoglycan suppresses IL-10-/- cell transfer-induced colitis progression. → Salmon proteoglycan suppresses Th1- and Th17-related factors in colitis mice. → Salmon proteoglycan enhances Foxp3 expression. -- Abstract: Proteoglycans (PGs) are complex glycohydrates which are widely distributed in extracellular matrix (ECM). PGs are involved in the construction of ECM, cell proliferation and differentiation. ECM components are involved in transduction of proinflammatory responses, but it is still unknown whether PGs are involved in inflammatory response. In this study, we investigated the effect of PG extracted from salmon cartilage on the progression of experimental colitis-induced in severe combined immunodeficiency mice by cell transfer from interleukin-10 (IL-10)-/- mice. IL-10-/- cell-transferred mice showed weight loss, colon shortening and histological appearance of mild colitis. Daily oral administration of PG attenuated the clinical progression of colitis in a dose-dependent manner. Colitis-induced mice showed the elevated expression of IFN-γ, IL-12, TNF-α, IL-21, IL-23p19, IL-6, IL-17A and retinoic acid-related orphan receptor γt (RORγt) in lamina propria mononuclear cells (LPMCs) and oral administration of PG suppressed the expression of these factors. Conversely, expression of Foxp3 that induces CD4+CD25+ regulatory T cells in LPMCs was enhanced by PG administration. These findings suggested that salmon PG attenuated the progression of colitis due to suppression of inflammatory response by enhancement of regulatory T cell induction.

    AIM: To compare thromboembolism rates between hospitalized patients with a diagnosis of ulcerative colitis and other hospitalized patients at high risk for thromboembolism. To compare thromboembolism rates between patients with ulcerative colitis undergoing a colorectal operation and other patients undergoing colorectal operations. METHODS: Data from the National Hospital Discharge Survey was used to compare thromboembolism rates between (1) hospitalized patients with a discharge diagnosis of ulcerative colitis and those with diverticulitis or acute respiratory failure, and (2) hospitalized patients with a discharge diagnosis of ulcerative colitis who underwent colectomy and those with diverticulitis or colorectal cancer who underwent colorectal operations. RESULTS: Patients diagnosed with ulcerative colitis had similar or higher rates of combined venous thromboembolism (2.03%) than their counterparts with diverticulitis (0.76%) or respiratory failure (1.99%), despite the overall greater prevalence of thromboembolic risk factors in the latter groups. Discharged patients with colitis that were treated surgically did not have significantly different rates of venous or arterial thromboembolism than those with surgery for diverticulitis or colorectal cancer. CONCLUSION: Patients with ulcerative colitis who do not undergo an operation during their hospitalization have similar or higher rates of thromboembolism than other medical patients who are considered to be high risk for thromboembolism.

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.

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.

  17. A case of reactive arthritis due to Clostridium difficile colitis

    Science.gov (United States)

    Essenmacher, Alex C.; Khurram, Nazish; Bismack, Gregory T.

    2016-01-01

    Reactive arthritis is an acute, aseptic, inflammatory arthropathy following an infectious process but removed from the site of primary infection. It is often attributed to genitourinary and enteric pathogens, such as Chlamydia, Salmonella, Shigella, Campylobacter, and Yersinia, in susceptible individuals. An uncommon and less recognized cause of this disease is preceding colonic infection with Clostridium difficile, an organism associated with pseudomembranous colitis and diarrhea in hospitalized patients and those recently exposed to antibiotics. Recognition of this association may be complicated by non-specific presentation of diarrhea, the interval between gastrointestinal and arthritic symptoms, and the wide differential in mono- and oligoarthritis. We present the case of a 61-year-old, hospitalized patient recently treated for C. difficile colitis who developed sudden, non-traumatic, right knee pain and swelling. Physical examination and radiographs disclosed joint effusion, and sterile aspiration produced cloudy fluid with predominant neutrophils and no growth on cultures. Diagnostic accuracy is enhanced by contemporaneous laboratory investigations excluding other entities such as gout and rheumatoid arthritis and other infections that typically precede reactive arthritis. Contribution of Clostridium infection to reactive arthritis is an obscure association frequently difficult to prove, but this organism is warranted inclusion in the differential of reactive arthritis.

  18. Benign retroperitoneal schwannoma presenting as colitis: A case report

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    We report a case of a patient presenting with clinical, radiological and endoscopic features of colitis due to a compressive left para-aortic mass. Total open surgical excision was performed, which resulted in complete resolution of colitis. Histopathology and immunohistochemistry revealed benign retroperitoneal schwannoma. These neural sheath tumors rarely occur in the retroperitoneum. They are usually asymptomatic but as they enlarge they may compress adjacent structures, which leads to a wide spectrum of nonspecific symptoms, including lumbar pain, headache, secondary hypertension, abdominal pain and renal colicky pain. CT and MR findings show characteristic features, but none are specific. Schwannoma can be isolated sporadic lesions, or associated with schwannomatosis or neurofibromatosis type Ⅱ (NF2). Although they vary in biological and clinical behavior, their presence is, in nearly every case, due to alterations or absence of the NF2 gene, which is involved in the growth regulation of Schwann cells. Both conditions were excluded by thorough mutation analysis. Diagnosis is based on histopathological examination and immunohistochemistry. Total excision is therapeutic and has a good prognosis. Schwannomatosis and NF2 should be excluded through clinical diagnostic criteria. Genetic testing of NF2 is probably not justified in the presence of a solitary retroperitoneal schwannoma.

    BACKGROUND Ulcerative colitis (UC) is characterized by recurrent episodes of inflammation limited to the mucosal layer of the colon. Calprotectin is a zinc and calcium binding protein derived from neutrophils and monocytes. It is easily detectable in tissue samples, body fluids, and stools, which makes it a potentially valuable marker of inflammation. The aim of the current study is to evaluate the value of fecal calprotectin (FC) as a marker of disease activity in patients with UC. METHODS Seventy three eligible subjects underwent ileocolonoscopy and multiple biopsies were obtained from different parts of the colon and terminal ileum. All patients underwent blood and stool sampling as well as an interview to assess the disease severity utilizing ulcerative colitis activity index (UCAI), subjectively. The diagnostic value of the FC in comparison with Mayo disease activity index as the gold standard technique, was then evaluated. RESULTS Mean FC level increased linearly according to Mayo disease activity index (r=0.44, p 21.4 ng/ml was able to discriminate between active and inactive phases of UC according to Mayo disease activity index>2 with 72.3% sensitivity and 73.1% specificity. The combination of FC > 21.4 ng/ml and UCAI score of 7 had a 46.8% sensitivity and 88% specificity to diagnose Mayo disease activity index >2. Furthermore, FC level 2. PMID:24829673

    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.

Case 1 was a 53-year-old woman, who had a history of undergoing radiation therapy for a uterine cervical cancer 11 years before. She was seen at the hospital because of constipation and pointed out a IIa-like lesion on the rectum by colonoscopy. Abdominoperineal resection was performed. The surgical specimen showed the IIa-like lesion on the rectum. Pathological findings revealed well-differentiated adenocarcinoma. Immunohistochemical staining of p53 showed positive cells in atrophic glands. Case 2 was a 62-year-old woman complaining of diarrhea. There was a previous history of receiving radiation therapy for a uterine cancer 20 years before. Colonoscopy showed a Borrmann type 2 cancer on the rectum. Abdominoperineal resection was performed. Histological findings revealed moderately differentiated adenocarcinoma invading to the propria muscle. The features of radiation colitis were observed around the cancer in the two cases which provided a clue to diagnose the lesions with radiation-induced cancer. (author)

  2. Cellulose supplementation early in life ameliorates colitis in adult mice.

    Full Text Available Decreased consumption of dietary fibers, such as cellulose, has been proposed to promote the emergence of inflammatory bowel diseases (IBD: Crohn disease [CD] and ulcerative colitis [UC] where intestinal microbes are recognized to play an etiologic role. However, it is not known if transient fiber consumption during critical developmental periods may prevent consecutive intestinal inflammation. The incidence of IBD peaks in young adulthood indicating that pediatric environmental exposures may be important in the etiology of this disease group. We studied the effects of transient dietary cellulose supplementation on dextran sulfate sodium (DSS colitis susceptibility during the pediatric period in mice. Cellulose supplementation stimulated substantial shifts in the colonic mucosal microbiome. Several bacterial taxa decreased in relative abundance (e.g., Coriobacteriaceae [p = 0.001], and other taxa increased in abundance (e.g., Peptostreptococcaceae [p = 0.008] and Clostridiaceae [p = 0.048]. Some of these shifts persisted for 10 days following the cessation of cellulose supplementation. The changes in the gut microbiome were associated with transient trophic and anticolitic effects 10 days following the cessation of a cellulose-enriched diet, but these changes diminished by 40 days following reversal to a low cellulose diet. These findings emphasize the transient protective effect of dietary cellulose in the mammalian large bowel and highlight the potential role of dietary fibers in amelioration of intestinal inflammation.

    Background/Aims: Inflammatory bowel disease (IBD) may also involve various extra-intestinal organs. Clinical studies have found asymptomatic/symptomatic pulmonary involvement in 1% to 6% of patients with IBD. The present study histopathologically investigated pulmonary involvement in an experimental model of colitis in order to demonstrate pulmonary tissue involvement in IBD and to expose potential etiological factors. It also explored the relation between inflammation and tissue concentrations of vascular endothelial growth factor (VEGF) and tumor necrosis factor α (TNF-α). Methods: The study comprised 24 male Wistar albino rats. The rats were divided into four groups of six rats each. Acute colitis was induced in two separate groups using either the dextran sulphate sodium (DSS) or trinitrobenzene sulfonic acid (TNBS) method, while the other two groups were used as controls for each model of colitis. Wallace scoring was used for macroscopic assessment of colitis, and the lungs were histopathologically examined. Concentrations of VEGF and TNF-α in pulmonary tissue were measured by the enzyme-linked immunosorbent assay method. Results: The number of animals that had alveolar hemorrhage was significantly higher in the TNBS-induced colitis and DSS-induced colitis groups compared to their own control groups (p = 0.015 and p = 0.015, respectively). VEGF and TNF-α concentrations in pulmonary tissues were significantly increased in both the TNBS colitis and DSS colitis groups compared to their own control groups (p = 0.002 and p = 0.004, respectively; and p = 0.002 and p = 0.002, respectively). Conclusions: The present study demonstrated that significant and serious histopathological changes directly associated with colitis occur in the lungs in IBD. PMID:27539446

    Full Text Available Stephen E Weis1,2 1Division of Dermatology, Department of Internal Medicine, University of North Texas Health Science Center at Fort Worth, 2Preventive Medicine Clinic, Tarrant County Public Health, Fort Worth, TX, USA Abstract: Anal squamous cell cancer is an uncommon malignancy caused by infection with oncogenic strains of Human papilloma virus. Anal cancer is much more common in immunocompromised persons, including those infected with Human immunodeficiency virus. High-grade anal intraepithelial neoplasia (HGAIN, the precursor of anal cancer, is identified by clinicians providing care for patients with anorectal disease, and is increasingly being identified during screening of immunosuppressed patients for anal dysplasia. The traditional treatment for HGAIN has been excision of macroscopic disease with margins. This approach is effective for patients with small unifocal HGAIN lesions. Patients with extensive multifocal HGAIN frequently have recurrence of HGAIN after excision, and may have postoperative complications of anal stenosis or fecal incontinence. This led to the suggestion by some that treatment for HGAIN should be delayed until patients developed anal cancer. Alternative approaches in identification and treatment have been developed to treat patients with multifocal or extensive HGAIN lesions. High-resolution anoscopy combines magnification with anoscopy and is being used to identify HGAIN and determine treatment margins. HGAIN can then be ablated with a number of modalities, including infrared coagulation, CO2 laser, and electrocautery. These methods for HGAIN ablation can be performed with local anesthesia on outpatients and are relatively well tolerated. High-resolution anoscopy-directed HGAIN ablation is evolving into a standard approach for initial treatment and then subsequent monitoring of a disease which should be expected to be recurrent. Another treatment approach for HGAIN is topical treatment, principally with 5

    Full Text Available Abstract Background Anal smears are increasingly being used as a screening test for anal squamous intraepithelial lesions (ASILs. This study was undertaken to assess the usefulness and limitations of anal smears in screening for ASILs. Methods The cytomorphological features of 200 consecutive anal smears collected in liquid medium from 198 patients were studied and findings were correlated with results of surgical biopsies and/or repeat smears that became available for 71 patients within six months. Results Adequate cellularity was defined as an average of 6 or more nucleated squamous cells/hpf. A glandular/transitional component was not required for adequacy. Dysplastic cells, atypical parakeratotic cells and bi/multinucleated cells were frequent findings in ASIL while koilocytes were infrequent. Smears from LSIL cases most frequently showed mildly dysplastic and bi/multinucleate squamous cells followed by parakeratotic cells (PK, atypical parakeratotic cells (APK, and koilocytes. HSIL smears contained squamous cells with features of moderate/severe dysplasia and many APKs. Features of LSIL were also found in most HSIL smears. Conclusions In this study liquid based anal smears had a high sensitivity (98% for detection of ASIL but a low specificity (50% for predicting the severity of the abnormality in subsequent biopsy. Patients with cytologic diagnoses of ASC-US and LSIL had a significant risk (46–56% of HSIL at biopsy. We suggest that all patients with a diagnosis of ASC-US and above be recommended for high resolution anoscopy with biopsy.

    Anal canal adenoma is an extremely rare disease that has the potential to transform into a malignant tumor. We herein presented a rare case of metachronous multiple adenomas of the anal canal. A 48-year-old woman underwent total colonoscopy following a positive fecal blood test. A 9-mm villous polyp arising from the posterior wall of the anal canal was removed by snare polypectomy. Histologically, the tumor was tubulovillous adenoma with high-grade dysplasia and the cut end was negative for tumor cells. Six years later, an elevated lesion, macroscopically five millimeters in size, was detected in the left wall of the anal canal in a follow-up colonoscopy. Local excision of the tumor was performed, and the lesion was pathologically confirmed to be tubular adenoma with high-grade dysplasia limited to the mucosa. The patient is currently alive without any evidence of recurrence for six months after surgery. Although she had a past history of cervical cancer, the multiple tumors arising in the anal canal were unlikely to be related to human papilloma virus infection. Our case report underscores the importance of careful observations throughout colonoscopy to detect precancerous lesions, particularly in anatomically narrow segments. PMID:26249723

    An interesting case of ulcerative colitis with an apparent change of Rhesus blood group typing is described. To our knowledge, this has not been reported before. We postulate that during the initial active phase of ulcerative colitis, an unknown D-like antigen, possibly bacterial in origin, could temporarily give rise to a Rhesus D-positive blood group typing in a patient with Rhesus D-negative blood type. Interestingly, with continuous immunosuppressive therapy for ulcerative colitis, the patient did not develop anti-D antibodies despite multiple transfusions with D-positive blood. PMID:1776013

    Ischemic colitis is an uncommon complication in patients with systemic lupus erythematosus (SIE). In previously reported cases of colitis caused by SLE, intestinal vasculitis is implicated as the causative process, but is rarely confirmed histologically. We described a case of a 32-year-old man with increased activity of SLE, who presented with hematochezia and abdominal pain due to ischemic colitis with small vessel vasculitis which was proven by sigmoidoscopic biopsy. The clinical course of the patient was improved after steroid and conservative management.

    A 76-year-old woman with a 5-mo history of recurrent diarrhea and generalized edema was admitted to our hospital. Colonoscopy revealed edematous mucosa, and histopathological examination was compatible with collagenous colitis. Protein leakage from the colon, particularly in the ascending portion, was identified on 99mTc-human serum albumin scintigraphy. Collagenous colitis associated with protein-losing enteropathy (PLE) without small bowel disease was diagnosed. Prednisolone treatment ameliorated diarrhea and hypoproteinemia. Collagenous colitis should be included in the differential diagnosis of chronic diarrhea with hypoproteinemia for appropriate management.

    Full Text Available Pyoderma gangrenosum is an extraintestinal manifestation of inflammatory bowel disease that can be therapeutically troublesome. We comment on the case of a patient with clinically inactive ulcerat-ive colitis who progressively developed necrotic lesions on both tibial aspects of his legs, which corresponded both clinically and histologically to pyoderma gangrenosum. Treatment with steroids and azathioprine could not control this complication. A single dose of infliximab 5 mg/kg was given, achieving an impressive response of the skin lesions followed by complete healing 3 months later. Infliximab can be useful in the management of refractory extraintestinal manifestations of inflammatory bowel disease.Dentro de las manifestaciones extraintestinales de la enfermedad inflamatoria intestinal, el pioderma gangrenoso plantea con frecuencia dificultades terapéuticas. Presentamos el caso de un enfermo diagnosticado de colitis ulcerosa, inactiva en ese momento, que presentó un pioderma gangrenoso en miembros inferiores y no respondió a esteroides y azatioprina. Se administró una dosis de 5 mg/kg de infliximab obteniendo una rápida mejoría de las lesiones y la completa curación a los 3 meses. Infliximab puede ser útil en manifestaciones extraintestinales de la enfermedad inflamatoria intestinal, como el pioderma gangrenoso, si no responden a los tratamientos habituales.

  19. Assessment of the influence of the inflammatory process on the activation of blood platelets and morphological parameters in patients with ulcerative colitis (colitis ulcerosa

    Full Text Available Ulcerative colitis (colitis ulcerosa is a non-specific inflammatory bowel disease of unknown etiology. The symptoms which are observed in the course of ulcerative colitis are: an increase in the number of leukocytes and blood platelets, an increase in the concentration of IL-6 and anemia. Blood platelets are the key element, linking the processes of hemostasis, inflammation and the repair of damaged tissues. Activation of blood platelets is connected with changes in their shape and the occurrence of the reaction of release. P-selectin appears on the surfaces of activated blood platelets and the concentration level of soluble P-selectin increases in the blood plasma. The aim of this study was to define whether the increased number of blood platelets in patients with ulcerative colitis accompanies changes in their activation and morphology. A total of 16 subjects with ulcerative colitis and 32 healthy subjects were studied. Mean platelet count, morphological parameters of platelets and MPC were measured using an ADVIA 120 hematology analyzer. Concentrations of sP-selectin and IL-6 in serum were marked by immunoassay (ELISA. MPC, concentration of sP-selectin and IL-6 were significantly higher in subjects with ulcerative colitis compared to those in the healthy group. There was a decrease of MPV in patients with ulcerative colitis, which is statistically significant. Chronic inflammation in patients with ulcerative colitis causes an increase in the number of blood platelets, a change in their morphology and activation. Decreased MPV value reflects activation and the role blood platelets play in the inflammatory process of the mucous membrane of the colon. A high concentration of sP-selectin, which is a marker of blood platelet activation, demonstrates their part in the inflammatory process. The increase in the concentration of sP-selectin correlated positively with the increase in concentration of IL-6. This is why it may be a useful marker

The way it acts on the dermo-epidermis has not been clearly described. Different studies reporting a relation, proportional or inverse, between isotretinoin and the occurrence or reactivation of an inflammatory bowel disease (IBD have been found in the literature. Although there are several hypotheses about how this substance can affect the bowel mucous in the pathogenesis of the disease, none of them are definitive. We present a new case where the mentioned relation was evident. Therefore we suggest that when a patient treated with this isomer presents symptoms suggesting IBD, an endoscopic procedure should be performed in order to rule out inflammatory mucous changes.

    Full Text Available Introduction: patients with ulcerative colitis (UC have a greater risk of developing colorectal cancer (CRC when compared to the general population. Epithelial dysplasia comes before this neoplasm, and thus endoscopic surveillance is recommended to these patients. This pilot study aims at establishing the incidence of dysplasia and CRC in patients with long-standing UC in our hospital. Material and methods: this is a prospective observational study performed in patients with a definite diagnosis of UC for more than 8 years. These patients were encouraged to enroll in an endoscopic surveillance program for CRC. All patients underwent colonoscopy and multiple biopsies every 18 to 24 months in order to detect epithelial dysplasia. Results: thirty-nine patients were included from January 1994 to December 2003. Half of them were males. Mean age was 52 ± 13 years. Mean duration of UC was 15 ± 8 years. Thirteen (35% patients had left colitis, and 26 (65% had pancolitis or extensive colitis. The presence of mild dysplasia was detected in four patients, on two occasions in one of them (13%; 95% CI: 6.1-33.5; the incidence of mild dysplasia was 1.3% patients per surveillance year. No severe dysplasia or CRCs were identified. Conclusion: the incidence of dysplasia in our area is lower than expected, and does not support surveillance programs for these patients. However, no definite conclusions may be drawn from such a small number of patients.Introducción: los pacientes con colitis ulcerosa (CU tienen un mayor riesgo de desarrollar cáncer colorrectal (CCR que la población general.

However, associating inflammatory diseases with specific microbial members of the microbiota is challenging, because clinically detectable inflammation and its treatment can alter the microbiota's composition. Immunologic checkpoint blockade with ipilimumab, a monoclonal antibody that blocks cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) signalling, is associated with new-onset, immune-mediated colitis. Here we conduct a prospective study of patients with metastatic melanoma undergoing ipilimumab treatment and correlate the pre-inflammation faecal microbiota and microbiome composition with subsequent colitis development. We demonstrate that increased representation of bacteria belonging to the Bacteroidetes phylum is correlated with resistance to the development of checkpoint-blockade-induced colitis. Furthermore, a paucity of genetic pathways involved in polyamine transport and B vitamin biosynthesis is associated with an increased risk of colitis. Identification of these biomarkers may enable interventions to reduce the risk of inflammatory complications following cancer immunotherapy. PMID:26837003

    AIM: To investigate efficacy and safety for granulocyte, monocyte apheresis in a population of pediatric patients with ulcerative colitis. METHODS: The ADAPT study was a prospective, open-label, multicenter study in pediatric patients with moderate, active ulcerative colitis with pediatric ulcerative colitis activity index (PUCAI) of 35-64. Patients received one weekly apheresis with Adacolumn® granulocyte, monocyte/macrophage adsorptive (GMA) apheresis over 5 consecutive weeks, optionally followed by up to 3 additional apheresis treatments over 3 consecutive weeks. The primary endpoint was the change in mean PUCAI between baseline and week 12; the secondary endpoint was improvement in PUCAI categorized as (Significant Improvement, PUCAI decrease of ≥ 35), Moderate Improvement (PUCAI decrease of 20 pediatric patients with moderate active Ulcerative Colitis. No new safety signals were reported. The present data contribute to considering GMA apheresis as a therapeutic option in pediatric patients having failed first line therapy. PMID:27158208

    Infective colitis can be a cause of massive lower gastrointestinal bleeding requiring acute surgical intervention. Causative organisms include entamoeba and histoplasma species. However, concurrent colonic infection with both these organisms is very rare, and the in vivo consequences are not known. A 58-year-old male presented initially to the physicians with pyrexia of unknown origin and bloody diarrhea. Amoebic colitis was diagnosed based on biopsies, and he was treated with metronidazole. Five days later...

    We report a case of successfully treated acute fulminant myocarditis induced by ulcerative colitis with extracorporeal life support and infliximab. Myocarditis is a rare but crucial complication during an exacerbation of inflammatory bowel disease. In our case, we applied extracorporeal membrane oxygenation (ECMO) for cardiac rest under impression of acute myocarditis associated with ulcerative colitis, and added infliximab for uncontrolled inflammation by corticosteroid. As a result, our patient was completely recovered with successful weaning of ECMO.
