    Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient's liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer.

    Full Text Available Idiopathic isolated cecal necrosis is a clinical problem characterized by right-sided inferior abdominal pain. It is rarely seen, develops due to decreased blood flow to the colon and, imitates acute appendicitis. Its clinical signs are similar to many illnesses causing sensitivity in the right inferior quadrant and, the diagnosis is generally determined during surgery. An 86-year-old male patient presented with the complaints of abdominal pain, trichiniasis, nausea and vomiting. Surgical intervention was decided when physical examination and laboratory results were taken into consideration. After diagnostic laparoscopy, right hemicolectomy was performed because of cecal necrosis. While the mortality and morbidity rates for ischemic bowel disease are high, prognosis for early diagnosed patients with isolated cecal necrosis is better, provided that timely surgical treatment is decided.

    Full Text Available Cecal perforation is an uncommon phenomenon in a pediatric population. It has been linked to a number of underlying medical conditions, which may result in focal inflammation or relative ischemia including hematologic malignancy, infection, and inflammatory bowel disease. We present an otherwise healthy 16-year-old male diagnosed with acute uncomplicated appendicitis on ultrasound, who was found to have cecal perforation with normal appendix intraoperatively, ultimately requiring ileocectomy. With this report, we aim to present the numerous pathophysiologic etiologies of cecal perforation, and to promote a comprehensive differential diagnosis despite the clinical and radiologic findings consistent with uncomplicated appendicitis.

    Low testosterone levels increase the risk for cardiovascular disease in men and lead to shorter life spans. Our recent study showed that androgen deprivation via castration altered fecal microbiota and exacerbated risk factors for cardiovascular disease, including obesity, impaired fasting glucose, excess hepatic triglyceride accumulation, and thigh muscle weight loss only in high-fat diet (HFD)-fed male mice. However, when mice were administered antibiotics that disrupted the gut microbiota, castration did not increase cardiovascular risks or decrease the ratio of dried feces to food intake. Here, we show that changes in cecal microbiota (e.g., an increased Firmicutes/Bacteroidetes ratio and number of Lactobacillus species) were consistent with changes in feces and that there was a decreased cecal content secondary to castration in HFD mice. Castration increased rectal body temperature and plasma adiponectin, irrespective of diet. Changes in the gut microbiome may provide novel insight into hypogonadism-induced cardiovascular diseases.

    Broccoli consumption brings many health benefits, including reducing the risk of cancer and inflammatory diseases. The objectives of this study were to identify global alterations in the cecal microbiota composition using 16S rRNA sequencing analysis and glucoraphanin (GRP) hydrolysis to isothiocyanates ex vivo by the cecal microbiota, following different broccoli diets. Rats were randomized to consume AIN93G (control) or different broccoli diets; AIN93G plus cooked broccoli, a GRP-rich powder, raw broccoli, or myrosinase-treated cooked broccoli. Feeding raw or cooked broccoli for four days or longer both changed the cecal microbiota composition and caused a greater production of isothiocyanates ex vivo. A more than two-fold increase in NAD(P)H: quinone oxidoreductase 1 activity of the host colon mucosa after feeding cooked broccoli for seven days confirmed the positive health benefits. Further studies revealed that dietary GRP was specifically responsible for the increased microbial GRP hydrolysis ex vivo, whereas changes in the cecal microbial communities were attributed to other broccoli components. Interestingly, a three-day withdrawal from a raw broccoli diet reversed the increased microbial GRP hydrolysis ex vivo. Findings suggest that enhanced conversion of GRP to bioactive isothiocyanates by the cecal microbiota requires four or more days of broccoli consumption and is reversible. PMID:28287418

    Behcet's disease (BD) has been recognized as multi-systemic chronic vasculitic disorder of recurrent inflammation, characterized by the involvement of multiple organs and resulting in orogenital ulcers, uveitis, and skin lesions. Involvement of the central nervous system, vessels, and intestines in BD often leads to a poor prognosis. Digestive manifestations in BD have been reported in up to 1-60% of cases, although the rate varies in different countries. The most frequent extra-oral sites of gastrointestinal involvement are the ileocecal region and the colon. Gastric or esophageal involvement is reported to be very rare. Moreover, there have been no reports on the simultaneous involvement of the esophagus, stomach, ileum, and colon. Here, we present a 55-year-old Korean man with intestinal BD and multiple ileal and colonic ulcerations complicated by perforation, gastric ulcer with bleeding followed by perforation, and esophageal ulcers with bleeding.

    2004-03-01

    Full Text Available RACIONAL: A doença de Crohn isolada do apêndice é doença de paciente jovem, relativamente rara, com quadro histopatológico semelhante ao da doença de Crohn típica. Seu quadro clínico, em geral, simula o da apendicite aguda, com manifestações protraídas e na palpação do abdome, além dos sinais de irritação peritonial, nota-se com freqüência, um tumor palpável. OBJETIVO: Apresentar um caso de doença de Crohn isolada do apêndice que se manifestou por enterorragia e cuja origem foi identificada pela colonoscopia. PACIENTE: Masculino, com 16 anos de idade, sem outras manifestações digestivas apresentou dois episódios de enterorragia com intervalo de cerca de 1 ano. No segundo episódio, a colonoscopia identificou o sangramento como proveniente do óstio apendicular. RESULTADO: Indicada a exploração cirúrgica, constatou-se que o ceco e o íleo eram normais e que o apêndice cecal estava com sinais inflamatórios e bloqueado pelo omento, realizando-se a apendicectomia. O exame anatomopatológico revelou tratar-se de processo inflamatório crônico com infiltrado linfoplasmocitário e granulomas esparsos, sugestivo de doença de Crohn. Em acompanhamento clínico, não apresentou manifestações de doença digestiva e a colonoscopia, realizada após 2 anos, não mostrou evidências de recidiva ou propagação da doença para o íleo. CONCLUSÃO: Neste caso, como nos demais relatados na literatura, a apendicectomia é possivelmente curativa, devendo o paciente ser acompanhado, pelo menos, por 5 anos. No diagnóstico diferencial das enterorragias em pacientes jovens, a doença de Crohn isolada do apêndice também pode ser considerada.BACKGROUND: Crohn’s disease confined to the appendix is relatively rare as a sole primary manifestation of the disease. Young people are more affected. The medical history and the physical examination are similar to the findings in acute appendicitis, but the manifestations are protracted. On

    Epizootic Rabbit Enteropathy (ERE) is a severe disease of unknown aetiology that mainly affects post-weaning animals. Its incidence can be prevented by antibiotic treatment suggesting that bacterial elements are crucial for the development of the disease. Microbial dynamics and host responses during the disease were studied. Cecal microbiota was characterized in three rabbit groups (ERE-affected, healthy and healthy pretreated with antibiotics), followed by transcriptional analysis of cytokines and mucins in the cecal mucosa and vermix by q-rtPCR. In healthy animals, cecal microbiota with or without antibiotic pretreatment was very similar and dominated by Alistipes and Ruminococcus. Proportions of both genera decreased in ERE rabbits whereas Bacteroides, Akkermansia and Rikenella increased, as well as Clostridium, γ-Proteobacteria and other opportunistic and pathogenic species. The ERE group displayed remarkable dysbiosis and reduced taxonomic diversity. Transcription rate of mucins and inflammatory cytokines was very high in ERE rabbits, except IL-2, and its analysis revealed the existence of two clearly different gene expression patterns corresponding to Inflammatory and (mucin) Secretory Profiles. Furthermore, these profiles were associated to different bacterial species, suggesting that they may correspond to different stages of the disease. Other data obtained in this work reinforced the notion that ERE morbidity and mortality is possibly caused by an overgrowth of different pathogens in the gut of animals whose immune defence mechanisms seem not to be adequately responding.

    Full Text Available Non specific cecal ulcer (NSCU is a rare entity described by Cruveilhier in 1832. NSCU has no specific presenting features and it can mimic a host of conditions like appendicitis, diverticulosis and colonic carcinoma. Earlier, this terminology was used to depict those ulcers where it was not possible to make the exact diagnosis. There are only a few cases where a specific preoperative diagnosis was made. The number of NSCUs being reported recently is less. This is due to the advent of newer diagnostic techniques to identify the etiology of these ulcers. Hence the term NSCU is no longer employed in current literature because a specific diagnosis is attained in most ulcers. Therefore the term NSCU is no longer valid and its use should be largely restricted to those cases where a specific diagnosis is not possible even after exhausting the currently available investigative techniques. This article provides an overview of this outdated term and outlines how to proceed when NSCU is encountered in clinical practice. [J Interdiscipl Histopathol 2013; 1(2.000: 85-88

    Gastrointestinal involvement of neurofibromatosis type 1 (NF1, Von Recklinghausen's disease) is generally associated with the upper gastrointestinal tract. Abdominal manifestation of NF1 includes several tumors such as malignant peripheral nerve sheath tumors, gastrointestinal stromal tumors and ampulla of vater tumors. However, colonic involvement in NF1 patients is rare. We report a case of a patient presenting with dysphagia, weight loss, intermittent abdominal pain and constipation caused by a single cecal neurofibroma obstructing the ileocecal valve. Also gastrointestinal involvement of the lower tract should be considered in patients with NF1 presenting with abdominal complaints.

    Immune stress is the loss of immune homeostasis by external forces. This study investigated the effects of different types of immune stress on growth performance, immunity, and the distribution of cecal microflora in broiler chickens. In total, 540 one-day-old Cobb 500 broilers were randomly assigned to receive 1 of 5 (n = 108 birds/group) treatments: 1) no vaccination; 2) simplified vaccination, which included the infectious bronchitis vaccine (H120), the inactivated avian influenza vaccine (AI), the live vaccine strain Clone-30 of the Newcastle disease virus (NDV), and the combined inactive vaccine for infectious bursal diseases and the Newcastle disease vaccine (ND-IB); 3) normal vaccination (simplified vaccination + second dose of ND-IB, H120, and AI); 4) lipopolysaccharide (LPS) stress (normal vaccination+LPS); or 5) cyclophosphamide (CPM) stress (normal vaccination+CPM).The results showed that the average BW and average feed intake decreased significantly after treatment with LPS or CPM (P Chickens that were challenged by LPS or CPM had a lower ileal CP digestibility than that of the control group (P chickens that were treated with LPS or CPM (P chickens were higher than those in the control group chickens at 21 and 42 d of age, respectively (P stress on the microbial populations of treated birds. These data suggest that broilers with simplified vaccinations or without vaccinations can achieve the same growth performance as broilers with general vaccinations, but immune stress can break the homeostasis of cecal microflora and impair intestinal mucosal immune function.

    Full Text Available Chickens are major source of food and protein worldwide. Feed conversion and the health of chickens relies on the largely unexplored complex microbial community that inhabits the chicken gut, including the ceca. We have carried out deep microbial community profiling of the microbiota in twenty cecal samples via 16S rRNA gene sequences and an in-depth metagenomics analysis of a single cecal microbiota. We recovered 699 phylotypes, over half of which appear to represent previously unknown species. We obtained 648,251 environmental gene tags (EGTs, the majority of which represent new species. These were binned into over two-dozen draft genomes, which included Campylobacter jejuni and Helicobacter pullorum. We found numerous polysaccharide- and oligosaccharide-degrading enzymes encoding within the metagenome, some of which appeared to be part of polysaccharide utilization systems with genetic evidence for the co-ordination of polysaccharide degradation with sugar transport and utilization. The cecal metagenome encodes several fermentation pathways leading to the production of short-chain fatty acids, including some with novel features. We found a dozen uptake hydrogenases encoded in the metagenome and speculate that these provide major hydrogen sinks within this microbial community and might explain the high abundance of several genera within this microbiome, including Campylobacter, Helicobacter and Megamonas.

    We herein report the case of a patient with a cecal cancer with simultaneous liver, spleen, and ovarian metastases as well as peritoneal dissemination who achieved a long-term survival. The patient was a 67-year-old female. Ileocecal resection with partial hepatectomy, splenectomy, simple total hysterectomy, bilateral salpingo-oophorectomy, and resection of the peritoneal dissemination were performed. The final diagnosis was Stage IV (T4a, N1, M1b[H1, P3, OTH]). Adjuvant chemotherapy was administered, but abdominal computed tomography(CT)revealed a metachronous liver metastasis 41 months later. We performed partial hepatectomy, and the patient continued adjuvant chemotherapy. The patient is currently alive and disease-free 30 months after the last operation, 72 months after the initial surgery.

    Endoscopic mucosal resection (EMR) allows the removal of flat or sessile lesions, laterally spreading tumors, and carcinoma of the colon or the rectum limited to the mucosa or the superficial submucosa. Acute appendicitis is the most common abdominal emergency requiring emergency surgery, and it is also a rare complication of diagnostic colonoscopy and therapeutic endoscopy, including EMR. In the case presented here, a 53-year-old female underwent colonoscopy due to a positive fecal occult blood test and was diagnosed with cecal adenoma. She was referred to our hospital and admitted for treatment. The patient had no other symptoms. EMR was performed, and 7 h after the surgery, the patient experienced right -lower abdominal pain. Laboratory tests performed the following day revealed a WBC count of 16000/mm(3), a neutrophil count of 14144/mm(3), and a C-reactive protein level of 2.20 mg/dL, indicating an inflammatory response. Computed tomography also revealed appendiceal wall thickening and swelling, so acute appendicitis following EMR was diagnosed. Antibiotics were initiated leading to total resolution of the symptoms, and the patient was discharged on the sixth post-operative day. Pathological analysis revealed a high-grade cecal tubular adenoma. Such acute appendicitis following EMR is extremely rare, and EMR of the cecum may be a rare cause of acute appendicitis.

  5. Modulations of the chicken cecal microbiome and metagenome in response to anticoccidial and growth promoter treatment.

    Full Text Available With increasing pressures to reduce or eliminate the use of antimicrobials for growth promotion purposes in production animals, there is a growing need to better understand the effects elicited by these agents in order to identify alternative approaches that might be used to maintain animal health. Antibiotic usage at subtherapeutic levels is postulated to confer a number of modulations in the microbes within the gut that ultimately result in growth promotion and reduced occurrence of disease. This study examined the effects of the coccidiostat monensin and the growth promoters virginiamycin and tylosin on the broiler chicken cecal microbiome and metagenome. Using a longitudinal design, cecal contents of commercial chickens were extracted and examined using 16S rRNA and total DNA shotgun metagenomic pyrosequencing. A number of genus-level enrichments and depletions were observed in response to monensin alone, or monensin in combination with virginiamycin or tylosin. Of note, monensin effects included depletions of Roseburia, Lactobacillus and Enterococcus, and enrichments in Coprococcus and Anaerofilum. The most notable effect observed in the monensin/virginiamycin and monensin/tylosin treatments, but not in the monensin-alone treatments, was enrichments in Escherichia coli. Analysis of the metagenomic dataset identified enrichments in transport system genes, type I fimbrial genes, and type IV conjugative secretion system genes. No significant differences were observed with regard to antimicrobial resistance gene counts. Overall, this study provides a more comprehensive glimpse of the chicken cecum microbial community, the modulations of this community in response to growth promoters, and targets for future efforts to mimic these effects using alternative approaches.

    2007-02-01

    Full Text Available Abstract Background Pancreatic cancer is often locally and distally aggressive, but initial presentation as cecal perforation is uncommon. Case presentation We describe a patient presenting with pneumoperitoneum, found at initial exploration to have a cecal perforation believed to be secondary to a large cecal adenoma, after palpation of the remainder of the colon revealed hard stool but no distal obstruction. Postoperatively, however, the patient progressed to large bowel obstruction and upon reexploration, a mass could now be delineated, encompassing the splenic flexure, splenic hilum, and distal pancreas. Histological evaluation determined this was locally invasive pancreatic adenocarcinoma, and therefore the true etiology of the original cecal perforation. Conclusion Any perforation localized to the cecum must be highly suspicious for a distal obstruction, as dictated by the law of LaPlace.

    Fibroblast growth factor (FGF) signaling to the epithelium and mesenchyme mediated by FGF10 and FGF9, respectively, controls cecal formation during embryonic development. In particular, mesenchymal FGF10 signals to the epithelium via FGFR2b to induce epithelial cecal progenitor cell proliferation. Yet the precise upstream mechanisms controlling mesenchymal FGF10 signaling are unknown. Complete deletion of Fgf9 as well as of Pitx2, a gene encoding a homeobox transcription factor, both lead to cecal agenesis. Herein, we used mouse genetic approaches to determine the precise contribution of the epithelium and/or mesenchyme tissue compartments in this process. Using tissue compartment specific Fgf9 versus Pitx2 loss of function approaches in the gut epithelium and/or mesenchyme, we determined that FGF9 signals to the mesenchyme via Pitx2 to induce mesenchymal Fgf10 expression, which in turn leads to epithelial cecal bud formation.

    Colonic lipoma is a well-documented benign neoplasia,endoscopically appearing as a smooth round yellowish polyp with a thick stalk or broad-based attachment. We describe a 63-year old woman with persistent abdominal pain, in whom colonoscopy revealed a cecal mass with malignant features. Based on the colonoscopy findings,right hemicolectomy was laparoscopically performed for a presumptive diagnosis of a cecal adenocarcinoma, but histological examination revealed a colonic lipoma with overlying mucosal ulceration.

    Clostridium perfringens causes enteric diseases in animals and humans. In poultry, avian-specific C. perfringens strains cause necrotic enteritis, an economically significant poultry disease that costs the global industry over $2 billion annually in losses and control measures. With removal of antibiotic growth promoters in some countries this disease appears to be on the rise. In experimental conditions used to study disease pathogenesis and potential control measures, reproduction of the disease relies on the use of predisposing factors such as Eimeria infection and the use of high protein diets, indicating complex mechanisms involved in the onset of necrotic enteritis. The mechanisms by which the predisposing factors contribute to disease progression are not well understood but it has been suggested that they may cause perturbations in the microbiota within the gastrointestinal tract. We inspected changes in cecal microbiota and short chain fatty acids (SCFA) induced by Eimeria and fishmeal, in birds challenged or not challenged with C. perfringens. C. perfringens challenge in the absence of predisposing factors did not cause significant changes in either the alpha or beta diversity of the microbiota nor in concentrations of SCFA. Moreover, there was no C. perfringens detected in the cecal microbiota 2 days post-challenge without the presence of predisposing factors. In contrast, both fishmeal and Eimeria caused significant changes in microbiota, seen in both alpha and beta diversity and also enabled C. perfringens to establish itself post challenge. Eimeria had its strongest influence on intestinal microbiota and SCFA when combined with fishmeal. Out of 6 SCFAs measured, including butyric acid, none were significantly influenced by C. perfringens, but their levels were strongly modified following the use of both predisposing factors. There was little overlap in the changes caused following Eimeria and fishmeal treatments, possibly indicating multiple routes for

    Cecal cannulation is necessary for sampling of intestinal contents for a variety of nutritional or digestive physiology studies. This report describes a 2-stage technique for permanent cecal cannulation in standing horses. For the first procedure, a right flank laparotomy is performed and a small pouch of the cecal base exteriorized and sutured to the body wall. The second procedure is performed approximately 1 wk later. During the second procedure, the exposed cecal pouch is removed and the cannula inserted. Ten horses were cannulated using this technique. After the first procedure, 1 horse developed a cecal impaction unresponsive to medical therapy and ruptured its cecum, whereas 2 other horses developed mild transient colic that responded to medical management. Insertion of the cecal cannula after creation of the stoma in the second procedure resulted in transient colic in 4 of 9 horses, but they responded to analgesic therapy in less than 24 h in all instances. The time to complete healing of the cannula site was approximately 30 d. The technique described in this report decreases the risk of peritonitis due to intestinal leakage and is technically easier to perform than previously described techniques.

    The role of colonic fermentation in providing energy was investigated in rats with small bowel transection (T) or 80% resection (SBR). Rats were randomized to receive for 12 d either saline (S) or the enteral solution (E) through a cecostomy to meet 30% of energy requirement; the rest (70%) was provided by parenteral nutrition. Although SBR-S rats lost weight significantly compared with d 1 of the study, SBR-E rats gained. Significantly greater carcass wet weight and fat were found in SBR-E and T-E rats compared with SBR-S and T-S rats. SBR-E and T-E rats had significantly greater colonic mucosal dry weight and protein compared with SBR-S and T-S rats. Cecal short-chain fatty acid (SCFA) contents were also significantly higher in SBR-E and T-E rats compared with SBR-S and T-S rats. There was no significant effect of surgery (T vs. SBR) on any of the variables studied. These results suggest that the products of fermentation of an enteral solution infused through a cecostomy contribute substantially to energy requirement, maintenance of body composition and nutritional status of rats.

    This experiment was conducted to evaluate the effects of feeding dietary fiber on cecal short-chain fatty acid (SCFA) concentration and cecal microbiota of broiler and laying-hen chicks. The lower fiber diet was based on corn-soybean meal (SBM) and the higher fiber diet was formulated using corn-SBM-dried distillers grains with solubles (DDGS) and wheat bran to contain 60.0 g/kg of both DDGS and wheat bran from 1 to 12 d and 80.0 g/kg of both DDGS and wheat bran from 13 to 21 d. Diets were formulated to meet or exceed NRC nutrient requirements. Broiler and laying-hen chicks were randomly assigned to the high and low fiber diets with 11 replicates of 8 chicks for each of the 4 treatments. One cecum from 3 chicks was collected from each replicate: one cecum underwent SCFA concentration analysis, one underwent bacterial DNA isolation for terminal restriction fragment length polymorphism (TRFLP), and the third cecum was used for metagenomics analyses. There were interactions between bird line and dietary fiber for acetic acid (P = 0.04) and total SCFA (P = 0.04) concentration. There was higher concentration of acetic acid (P = 0.02) and propionic acid (P laying-hen chicks. TRFLP analysis showed that cecal microbiota varied due to diet (P = 0.02) and chicken line (P = 0.03). Metagenomics analyses identified differences in the relative abundance of Helicobacter pullorum and Megamonas hypermegale and the genera Enterobacteriaceae, Campylobacter, Faecalibacterium, and Bacteroides in different treatment groups. These results provide insights into the effect of dietary fiber on SCFA concentration and modulation of cecal microbiota in broiler and laying-hen chicks.

    The gut microbiota is considered a relevant factor in obesity and associated metabolic diseases, for which postmenopausal women are particularly at risk. Increasing physical activity has been recognized as an efficacious approach to prevent or treat obesity, yet the impact of physical activity on the microbiota remains under-investigated. We examined the impacts of voluntary exercise on host metabolism and gut microbiota in ovariectomized (OVX) high capacity (HCR) and low capacity running (LCR) rats. HCR and LCR rats (age = 27 wk) were OVX and fed a high-fat diet (45% kcal fat) ad libitum and housed in cages equipped with (exercise, EX) or without (sedentary, SED) running wheels for 11 wk (n = 7-8/group). We hypothesized that increased physical activity would hinder weight gain, increase metabolic health and shift the microbiota of LCR rats, resulting in populations more similar to that of HCR rats. Animals were compared for characteristic metabolic parameters including body composition, lipid profile and energy expenditure; whereas cecal digesta were collected for DNA extraction. 16S rRNA gene-based amplicon Illumina MiSeq sequencing was performed, followed by analysis using QIIME 1.8.0 to assess cecal microbiota. Voluntary exercise decreased body and fat mass, and normalized fasting NEFA concentrations of LCR rats, despite only running one-third the distance of HCR rats. Exercise, however, increased food intake, weight gain and fat mass of HCR rats. Exercise clustered the gut microbial community of LCR rats, which separated them from the other groups. Assessments of specific taxa revealed significant (p<0.05) line by exercise interactions including shifts in the abundances of Firmicutes, Proteobacteria, and Cyanobacteria. Relative abundance of Christensenellaceae family was higher (p = 0.026) in HCR than LCR rats, and positively correlated (p<0.05) with food intake, body weight and running distance. These findings demonstrate that exercise differentially impacts

    One hundred and forty-four Avin broilers (1 d old) were randomly divided into six treatments, with three replicates of eight birds each to investigate the effect of different oligosaccharides on index of immune organ, cecal weight and microflora in broilers. The control group (Group Ⅰ) was fed with corn-soybean meal as basal diet, and the trial groups (group Ⅱ, Ⅲ, Ⅳ, Ⅴ and Ⅵ ) were fed with basal diet plus 0.1% manoligosaccharides (MOS), 0.3% soybean-oligosaccharides (SBOS), 0.3% fructooligosaccharides (FOS), 0.3% α -glucooligosaccharides(α -GOS) and 0.03% chlortetracycline (CTC), respectively. The results showed that oligosaccharides supplementation significantly (P<0.05) increased bifidobacteria concentration ofyoung broilers and did not affect on bifidobacteria or escherichia coli concentration of the birds ( P >0.05). Cecal weights of 21 d old broilers fed with FOS and α -GOS were significantly (P <0.05) increased, higher than those with MOS and SBOS, but addition of oligosaccharides had no effect on the birds. The effect of oligosaccharides on the cecal length was the same as on the cecal weights. Oligosaccharides supplement did not affect on indexes of immune organs.

    The pattern of metabolites produced by the gut microbiome comprises a phenotype indicative of the means by which that microbiome affects the gut. We characterized that phenotype in mice by conducting metabolomic analyses of the colonic-cecal contents, comparing that to the metabolite patterns of feces in order to determine the suitability of fecal specimens as proxies for assessing the metabolic impact of the gut microbiome. We detected a total of 270 low molecular weight metabolites in colonic-cecal contents and feces by gas chromatograph, time-of-flight mass spectrometry (GC-TOF) and ultra-high performance liquid chromatography, quadrapole time-of-flight mass spectrometry (UPLC-Q-TOF). Of that number, 251 (93%) were present in both types of specimen, representing almost all known biochemical pathways related to the amino acid, carbohydrate, energy, lipid, membrane transport, nucleotide, genetic information processing, and cancer-related metabolism. A total of 115 metabolites differed significantly in relative abundance between both colonic-cecal contents and feces. These data comprise the first characterization of relationships among metabolites present in the colonic-cecal contents and feces in a healthy mouse model, and shows that feces can be a useful proxy for assessing the pattern of metabolites to which the colonic mucosum is exposed.

    The present study was conducted to investigate whether dietary essential oils could affect growth performance, relative organ weights, cecal microflora, immune responses and blood profiles of broiler chickens fed on diets containing different nutrient densities. A total of eight hundred-forty 1-d-old male broiler chicks were randomly allotted into twenty-eight pens (7 pens per treatment, 30 chicks per pen). There were four experimental diets containing two different nutrient densities and supplemented with or without essential oils. Experimental period lasted for 35 days. No clear interaction between nutrient density and essential oils on any of growth performance-related parameters was observed. Live body weights were affected (pnutrient density at 21 days and by dietary essential oils at 35 days. Essential oils significantly (pnutrient density. There were significant treatment interactions (pnutrient density did not influence the relative percentages of breast and leg meats, the population of cecal microflora, blood parameters and antibody titers against Newcastle disease and infectious bronchitis in broiler chickens. It was concluded that dietary essential oils, independent to nutrient density, failed to stimulate feed intake, but increased growth performance in broiler chickens.

    A 78-year-old woman presented with fever, severe abdominal pain, and distension. She had been institutionalized for depression and senile dementia. Laboratory examinations disclosed a leucocytosis (WBC:12 500/μL) and elevated levels of serum C-reactive protein (2.8 mEq/L). Diagnosis of acute cecal volvulus was made from a "coffee bean sign" on an abdominal computed tomography and a "beak sign" on a gastrographin enema. An emergent laparotomy confirmed the diagnosis and an ileo-colectomy with primary anastomosis wascarried out. The patient recovered after intensive respiratory care and fluid therapy, and then returned to her former institution. A review of Japanese literature disclosed that:(1) a marked increase of aged patients with mental disability presenting with cecal volvulus, (2) adoption of ileo-colectomy as the standard surgical procedure, and (3) improved survival of the patients, were observed in the last decade.

    Full Text Available Differences in quantity of cecal microbiota in broiler chickens from conventional and pasture rearing were investigated by cultivation. Rearing on pasture brings stress reduction and increases comfort and bird welfare, which leads to products with better taste and flavour compared to conventionally produced broiler chickens. A difference in cecal settlement of general anaerobes, coliforms, lactic acid bacteria, and campylobacters and salmonellas in the two different rearing systems was addressed. Whereas numbers of total anaerobes and lactic acid bacteria were not affected, those of coliforms were significantly reduced in pasture rearing. Campylobacters were found only in pasture-reared chickens (in 28% of animals. Salmonellas were not detected in any of the systems.

On day 21, twenty piglets were randomly selected (one from each replicate to slaughter and investigate the population and diversity of cecal microorganisms. The results showed that the diets containing 175 and 250 mg/kg-1 copper improved the average daily gain (ADG by 51% and 60% and decreased the feed to gain ratio (F/G by 21% and 16%, respectively. Adding 175 or 250 mg/kg-1 copper improved crude protein, ether extract, calcium and phosphorus digestibility. Viable counts of Enterobacteriaceae and Lactobacilli in cecum tended to be reduced, while the concentrations of cecal volatile fatty acids (VFA were increased in pigs fed diet supplemented as copper level increased. Polymerase chain reaction (PCR results showed that adding 175 or 250 mg/kg-1 copper reduced the lactobacilli in cecum. Denaturing gradient gel electrophoresis (DGGE maps showed that band numbers and intensity of cecal bacterial 16S rDNA decreased as the copper levels increased. The results suggested that the effects of high dietary copper on microflora and their activities and metabolic products might contribute to the intestinal health and result in improved growth performance.

    Antimicrobials are sometimes given to food animals at low doses in order to promote faster growth. However, the mechanisms by which those drugs improve performance are not fully understood. This study aimed to investigate the impact of zinc bacitracin (55g/ton), enramycin (10g/ton); halquinol® (30g/ton); virginiamycin (16,5g/ton) and avilamycin (10g/ton) on the cecal microbiota of broiler chicken, compared to a control group. Six hundred and twenty four chicks (Cobb 500) arriving to an experimental unit were randomly assigned into each treatment with four repetitions per treatment. The cecal content of 16 animals per treatment (n = 96) was used for DNA extraction and sequencing of the V4 region of the 16S rRNA gene using Illumina technology. The use of antimicrobials induced significant changes in membership but not in structure of the cecal microbiota compared to the control group, suggesting a greater impact on the less abundant species of bacteria present in that environment. Halquinol was the only drug that did not affect microbial membership. Firmicutes comprised the major bacterial phylum present in the cecum of all groups. There was no statistical difference in relative abundances of the main phyla between treated animals and the control group (all P>0.05). Treatment with enramycin was associated with decreased richness and with lower relative abundance of unclassified Firmicutes, Clostridium XI, unclassified Peptostreptococcaceae (all Pchicken under controlled conditions and add new insights to the current knowledge on how AGPs affect the cecal microbiota of chicken.

    Two studies were conducted to study regulatory T cell [Treg (CD4⁺CD25⁺)] properties during the establishment of a persistent intestinal infection in broiler chickens. Four-day-old broiler chicks were orally gavaged with 5 × 10⁶ CFU/mL Salmonella enteritidis (S. enteritidis) or sterile PBS (control). Samples were collected at 4, 7, 10, and 14 d postinfection. There was a significant (P 0.05) when compared to that of noninfected control birds. At a lower effector/responder cell ratio of 0.25:1, CD4⁺CD25⁺ cells from cecal tonsils of Salmonella-infected birds suppressed T cell proliferation at d 7 and 14 post-S. enteritidis infection, while CD4⁺CD25⁺ cells from noninfected control groups did not suppress T cell proliferation. In the second studu, 1-day-old chickens were orally gavaged with PBS (control) or 1.25 × 10⁸ CFU/bird S. enteritidis. At 7 and 21 d post-Salmonella infection, CD25⁺ cells collected from cecal tonsils of S. enteritidis-infected birds and restimulated in vitro with Salmonella antigen had higher (P 0.05) between the Salmonella-infected and control birds. In conclusion, a persistent intestinal S. enteritidis infection increased the Treg percentage, suppressive properties, and IL-10 mRNA amounts in the cecal tonsils of broiler birds.

    Preservation of indigenous gastrointestinal microbiota is deemed to be critical for successful captive breeding of endangered wild animals, yet its biology is poorly understood. Here, we investigated cecal bacterial communities in wild Japanese rock ptarmigans (Lagopus muta japonica) and compared them with those in Svalbard rock ptarmigans (L. m. hyperborea) in captivity. Ultra-deep sequencing of 16S rRNA gene indicated that the community structure of cecal microbiota in wild rock ptarmigans was remarkably different from that in captive Svalbard rock ptarmigans. Fundamental differences between bacterial communities in the two groups of birds were detected at the phylum level. Firmicutes, Actinobacteria, Bacteroidetes and Synergistetes were the major phyla detected in wild Japanese rock ptarmigans, whereas Firmicutes alone occupied more than 80% of abundance in captive Svalbard rock ptarmigans. Furthermore, unclassified genera of Coriobacteriaceae, Synergistaceae, Bacteroidaceae, Actinomycetaceae, Veillonellaceae and Clostridiales were the major taxa detected in wild individuals, whereas in zoo-reared birds, major genera were Ruminococcus, Blautia, Faecalibacterium and Akkermansia. Zoo-reared birds seemed to lack almost all rock ptarmigan-specific bacteria in their intestine, which may explain the relatively high rate of pathogenic infections affecting them. We show evidence that preservation and reconstitution of indigenous cecal microflora are critical for successful ex situ conservation and future re-introduction plan for the Japanese rock ptarmigan.

    Full Text Available The gut microbiota is considered a relevant factor in obesity and associated metabolic diseases, for which postmenopausal women are particularly at risk. Increasing physical activity has been recognized as an efficacious approach to prevent or treat obesity, yet the impact of physical activity on the microbiota remains under-investigated. We examined the impacts of voluntary exercise on host metabolism and gut microbiota in ovariectomized (OVX high capacity (HCR and low capacity running (LCR rats. HCR and LCR rats (age = 27 wk were OVX and fed a high-fat diet (45% kcal fat ad libitum and housed in cages equipped with (exercise, EX or without (sedentary, SED running wheels for 11 wk (n = 7-8/group. We hypothesized that increased physical activity would hinder weight gain, increase metabolic health and shift the microbiota of LCR rats, resulting in populations more similar to that of HCR rats. Animals were compared for characteristic metabolic parameters including body composition, lipid profile and energy expenditure; whereas cecal digesta were collected for DNA extraction. 16S rRNA gene-based amplicon Illumina MiSeq sequencing was performed, followed by analysis using QIIME 1.8.0 to assess cecal microbiota. Voluntary exercise decreased body and fat mass, and normalized fasting NEFA concentrations of LCR rats, despite only running one-third the distance of HCR rats. Exercise, however, increased food intake, weight gain and fat mass of HCR rats. Exercise clustered the gut microbial community of LCR rats, which separated them from the other groups. Assessments of specific taxa revealed significant (p<0.05 line by exercise interactions including shifts in the abundances of Firmicutes, Proteobacteria, and Cyanobacteria. Relative abundance of Christensenellaceae family was higher (p = 0.026 in HCR than LCR rats, and positively correlated (p<0.05 with food intake, body weight and running distance. These findings demonstrate that exercise differentially

    AIM:To develop a new formulation with hydroxy propyl methyl cellulose and Shellac coating for extended and selective delivery of butyrate in the ileo-caecal region and colon.METHODS:One-gram sodium butyrate coated tablets containing 13C-butyrate were orally administered to 12 healthy subjects and 12 Crohn's disease patients and the rate of 13C-butyrate absorption was evaluated by 13CO2 breath test analysis for eight hours.Tauroursodeoxycholic acid(500 mg)was co-administered as a biomarker of oro-ileal transit time to determine also the site of release and absorption of butyrate by the time of its serum maximum concentration.RESULTS:The coated formulation delayed the 13C-butyrate release by 2-3 h with respect to the uncoated tablets.Sodium butyrate was delivered in the intestine of all subjects and a more variable transit time was found in Crohn's disease patients than in healthy subjects.The variability of the peak 13CO2 in the kinetic release of butyrate was explained by the inter-subject variability in transit time.However,the coating chosen ensured an efficient release of the active compound even in patients with a short transit time.CONCLUSION:Simultaneous evaluation of breath 13CO2 and tauroursodeoxycholic acid concentrationtime curves has shown that the new oral formulation consistently releases sodium butyrate in the ileo-cecal region and colon both in healthy subjects and Crohn's disease patients with variable intestinal transit time.This formulation may be of therapeutic value in inflammatory bowel disease patients due to the appropriate release of the active compound.

    In ruminants, gastrointestinal recycling of urea is acutely enhanced by fibre-rich diets that lead to high ruminal concentration of short chain fatty acids (SCFA), while high ammonia has inhibitory effects. This study attempted to clarify if urea flux to the porcine cecum is similarly regulated. Thirty-two weaned piglets were fed diets containing protein (P) of poor prececal digestibility and fibre (F) at high (H) or low levels (L) in a 2 × 2 factorial design. After slaughter, cecal content was analyzed and the cecal mucosa incubated in Ussing chambers to measure the effect of pH, SCFA and NH4 (+) on the flux rates of urea, short-circuit current (I sc) and tissue conductance (G t). NH4 (+) significantly enhanced I sc (from 0.5 ± 0.2 to 1.2 ± 0.1 μEq cm(-2) h(-1)). No acute effects of SCFA or ammonia on urea flux were observed. Tissue conductance was significantly lower in the high dietary fibre groups irrespective of the protein content. Only the HP-LF group emerged as different from all others in terms of urea flux (74 ± 6 versus 53 ± 3 nmol cm(-2) h(-1)), associated with higher cecal ammonia concentration and reduced fecal consistency. The data suggest that as in the rumen, uptake of ammonia by the cecum may involve electrogenic transport of the ionic form (NH4 (+)). In contrast to findings in the rumen, neither a high fibre diet nor acute addition of SCFA enhanced urea transport across the pig cecum. Instead, a HP-LF diet had stimulatory effects. A potential role for urea recycling in stabilizing luminal pH is discussed.

    INTRODUCTION: Intussusception in adults is an infrequent cause of intestinal occlusion that is usually due to neoplasm lesions. The unspecific nature of the clinical presentation often delays diagnosis. It is most commonly emergency explorative laparotomy which clarifies the etiology of the occlusion. The authors report a case of intestinal occlusion caused by ileocecal-colonic invagination with a small cecal adenocarcinoma as lead point, in a 74-year-old woman. CASE REPORT: A 74-year-old woman came to the Emergency Department, complaining of crampy pain in the mid- and lower abdomen. An abdominal ultrasound revealed a "pseudokidney sign" apparently involving the cecum. Because there were no clear signs of occlusion, the patient was dicharged on the same day. Three days later, upon admission, the patient complained of episodes of abdominal pain with intervals of moderate well-being, associated with nausea, vomiting and an inability to pass stool (but not gas) for 36 hours. On clinical examination her abdomen was distended and tender on palpation in all quadrants, especially in the right iliac fossa where a large mass could be felt. Standard abdominal x-Ray documented gaseous distension of some loops of the jejunum-ileum with some air-fluid level. The patient underwent an abdominal CT scan which showed advanced intussusception that appeared to be ileocolic and multiple enlarged lymphnodes were found in the invaginated mesentery at the base of which there appears to be a thickening of the intestinal wall that is probably neoplastic in nature. The patient underwent explorative laparotomy. Ileocecal-colonic intussusception caused by a cecal growth 5 cm in diameter was found on examination of the surgical specimen. Histology showed that the cause of the large swelling of the ascending colon was a vegetating ulcerated adenocarcinoma (medium grade differentiation: G2), measuring 6.5x 4.0 cm, arising from a tubulovillous adenoma infiltrating the submucosa.

    Full Text Available Pylephlebitis is an uncommon complication of uncontrolled intra-abdominal infection that is associated with high morbidity and mortality. We present our experience with a unique case of cecal diverticulitis and septic thrombophlebitis of the superior mesenteric vein that was promptly diagnosed with high-resolution imaging and blood cultures. Antibiotic and anticoagulation therapy was instituted on confirming the diagnosis with magnetic resonance imaging (MRI to control the infection and prevent propagation of the thrombus. Our case report raises awareness about a rare and potentially fatal condition and provides appropriate imaging supplementation to aid in timely diagnosis.

    The pathogenicity of Trichomonas gallinarum (TG) in turkeys and chickens was assessed in a series of four experiments. TG was shown to be resistant to freezing for a period of 1 hr at -20 C; birds administered an emulsion of previously frozen TG were readily infected. Young birds receiving this inoculum were more likely to be infected with TG in both ceca compared with birds administered TG emulsion that had remained at room temperature for the same length of time. In this and other experiments, birds infected with the parasite consistently produced a yellow frothy liquid in the ceca, as well as small raised papulae on the mucosal surface of the ceca. Histologically, the lesions were located in the lamina propria, with openings that extended from the apex of the lesion to the crypts. The lamina propria was consistently infiltrated by lymphocytes and scattered heterophiles. Although TG is likely involved in the pathogenesis of the lesions, the resulting pathology could not be linked definitively to TG alone because inoculation was performed with a cecal contents homogenate containing significant numbers of cecal bacteria. Combined infections of TG and Eimeria adenoides (EA) were also studied. Turkeys administered both parasites were more frequently infected with TG in both ceca compared with those that received TG alone. Ceca infected with TG alone tended to be enlarged and gas filled, whereas those infected with the combination of TG and EA were smaller and usually lacked the yellow frothy liquid contents.

    Full Text Available The aim of the present study was to evaluate the effect of purslane on immune responses and cecal microflora composition of broiler chickens. One hundred forty four day old broiler chicks (Ross 308 were allocated randomly in 3 groups and 4 replicates to receive diets supplemented with 0 (control, 1 and 2 % of dried purslane. At 21 and 35 days of age 1 mL of sheep red blood cell (SRBC injected to 2 broilers of each replicate and blood samples were taken 7 days after each injection. Eight chicks per treatment at the age of 42 d were killed and the number of coliforms, E-Coli and Lactobacillus bacteria populations in ceca were enumerated on appropriate bacteriological media. There were no significant different in primary and secondary antibody titer against SRBC and no different between the treatments for proportional weight of bursa, thymus and spleen. The results of experiment indicated that use of purslane significantly increased Lactobacillus and decreased E-Coli bacteria population. Use of purslane had no effect on coliforms bacteria population. It is concluded that purslane inclusion had a positive significant effect on cecal microflora composition.

  4. Investigation into Host Selection of the Cecal Acetogen Population in Rabbits after Weaning.

    Full Text Available Homoacetogenic bacteria have received attention as a hydrogenotrophic population that offers a significant energetic advantage to the host animal. Reductive acetogenesis is likely an important hydrogen disposal mechanism in the cecum of rabbits. However, molecular ecology information about cecal acetogen candidates has rarely been reported. To better understand the effect of host selection in the rabbit cecal acetogen community with respect to growth, rabbits at four different age stages (30, 60, 120 and 180 days with the same diet were studied. Although the abundance of potential acetogens and methanogens was high in the cecum of rabbits undergoing growth, many novel potential acetogen populations were observed in the cecum of rabbits across all age groups. Young and adult rabbits had their own distinct acetogen community although they received the same diet, which suggests that as the rabbit ages, acetogens in the cecum undergo developmental changes because of host selection that are independent of diet, and perhaps the different acetogen communities result in different hydrogenotrophic characteristics. The within-group similarity increased with age, indicating that the acetogen community converges to a more homogeneous and stable arrangement with aging.

    Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS) qualitatively and quantitatively measured resistant starch (RS) in rat cecal contents. Fisher 344 rats were fed diets of 55% (w/w, dry basis) starch for 8 weeks. Cecal contents were collected from sacrificed rats. A corn starch control was compared against three RS diets. The RS diets were high-amylose corn starch (HA7), HA7 chemically modified with octenyl succinic anhydride, and stearic-acid-complexed HA7 starch. To calibrate the FTIR-PAS analysis, samples from each diet were analyzed using an enzymatic assay. A partial least-squares cross-validation plot generated from the enzymatic assay and FTIR-PAS spectral results for starch fit the ideal curve with a R2 of 0.997. A principal component analysis plot of components 1 and 2 showed that spectra from diets clustered significantly from each other. This study clearly showed that FTIR-PAS can accurately quantify starch content and identify the form of starch in complex matrices.

    Ceftobiprole and ceftobiprole medocaril did not promote growth of or toxin production by Clostridium difficile in mouse cecal contents, whereas ceftazidime, cefoxitin, ceftriaxone, cefotaxime, and ertapenem did. The relatively low propensity of ceftobiprole to promote C. difficile was attributable to inhibitory activity against C. difficile and sparing of anaerobic microflora.

    Bile acids (BAs) act as signaling molecules in various physiological processes, and are related to colonic microbiota composition as well as to different types of dietary fat and fiber. This study investigated whether guar gum and pectin-two fibers with distinct functional characteristics-affect BA profiles, microbiota composition, and gut metabolites in rats. Low- (LM) or high-methoxylated (HM) pectin, and low-, medium-, or high-molecular-weight (MW) guar gum were administered to rats that were fed either low- or high-fat diets. Cecal BAs, short-chain fatty acids (SCFA) and microbiota composition, and plasma lipopolysaccharide-binding protein (LBP) levels were analyzed, by using novel methodologies based on gas chromatography (BAs and SCFAs) and 16S rRNA gene sequencing on the Illumina MiSeq platform. Strong correlations were observed between cecal BA and SCFA levels, microbiota composition, and portal plasma LBP levels in rats on a high-fat diet. Notably, guar gum consumption with medium-MW increased the cecal amounts of cholic-, chenodeoxycholic-, and ursodeoxycholic acids as well as α-, β-, and ω-muricholic acids to a greater extent than other types of guar gum or the fiber-free control diet. In contrast, the amounts of cecal deoxycholic- and hyodeoxycholic acid were reduced with all types of guar gum independent of chain length. Differences in BA composition between pectin groups were less obvious, but cecal levels of α- and ω-muricholic acids were higher in rats fed LM as compared to HM pectin or the control diet. The inflammatory marker LBP was downregulated in rats fed medium-MW guar gum and HM pectin; these two fibers decreased the cecal abundance of Oscillospira and an unclassified genus in Ruminococcaceae, and increased that of an unclassified family in RF32. These results indicate that the molecular properties of guar gum and pectin are important for their ability to modulate cecal BA formation, gut microbiota composition, and high-fat diet induced

    Full Text Available Safety of either LigaSure or rubber band in closing inflamed appendiceal stump in acute appendicitis has been less investigated. In this study, cecal ligation followed by resecting inflamed cecum was performed to mimic appendectomy in a rat model of acute appendicitis. Rats were sacrificed immediately (Group A and 7 days (Group B after cecal resection, respectively. The cecal stumps were closed by silk ligature (S, 5 mm LigaSure (L, or rubber band (R. Seven days after cecal resection, the LigaSure (BL and silk subgroups (BS had significantly less intra-abdominal adhesion and better laparotomy wound healing than rubber band subgroup (BR. The initial bursting pressure at cecal stump was comparable among the three methods; along with tissue healing process, both BL and BS provided a higher bursting pressure than BR 7 days after appendectomy. BL subgroup had more abundant hydroxyproline deposition than BS and BR subgroup. Furthermore, serum TNF-α in BR group kept persistently increasing along with time after cecal resection. Thus, the finding that LigaSure but not rubber band is safe in sealing off the inflamed cecal stump in rat model of acute appendicitis suggests the possibility of applying LigaSure for appendectomy via single port procedure or natural orifice transluminal endoscopic surgery (NOTES.

    White Wrolstad turkeys were each inoculated with 100,000 Eimeria adenoides oocysts and killed on days 4-14 postinoculation. Tissue samples, obtained from 4 areas of the ceca comparable to areas examined in chickens infected with E. tenella in previous studies, were processed by a modification of the osmium-thiocarbo-hydrazide-osmium technique and examined with a scanning electron microscope. The pathologic situation found in turkeys was slightly different from that in the ceca of chickens infected with E. tenella. The mucosal lesions are most severe at the proximal end of an infected cecum. Surface disruption was far less severe than with cecal coccidiosis in chickens of the same age exposed to an equal number of infective oocysts. Rupture of the epithelial cell often caused the mucosal surface to present a honeycomb appearance. Some specific stages of the life cycle were identified, including schizonts and oocysts.

    Sodium polystyrene sulfonate (SPS) is a medication commonly used for the treatment of hyperkalemia. There have been many cases of colonic necrosis and perforation associated with administration of SPS. There are very few such cases reported in renal transplant patients. We present a case of renal transplant recipient who developed cecal perforation after a single oral dose of SPS. She had no signs or symptoms suggestive of intestinal perforation and was incidentally diagnosed with it on abdominal imaging performed to find cause of acute blood loss anemia. This case underlines the importance of recognizing this severe and potentially life-threatening complication associated with SPS. The clinicians should also consider renal/solid organ transplant and immunosuppression as potential risk factors.

    Full Text Available Duplication cysts of the alimentary tract are very rare congenital anomalies. Out of all these cases, two-thirds of them manifest before the age of 2 years. They are common in ileum, but very rare in cecum. Some of them may remain asymptomatic and present in the adulthood. The lesion may be tubular or cystic. Several theories have been postulated, but true etiology is not known. We hereby report a case of a 10-year-old female who presented with abdominal pain in the pediatric surgery outpatient department. Diagnosis of cecal duplication cyst was confirmed on histopathology. This report implies that although alimentary tract duplications are rare, they should be considered in the differential diagnosis of children who presents with acute abdominal pain.

  16. Cecal Ligation and Puncture Results in Long-Term Central Nervous System Myeloid Inflammation.

    Directory of Open Access Journals (Sweden)

    Benjamin H Singer

    Full Text Available Survivors of sepsis often experience long-term cognitive and functional decline. Previous studies utilizing lipopolysaccharide injection and cecal ligation and puncture in rodent models of sepsis have demonstrated changes in depressive-like behavior and learning and memory after sepsis, as well as evidence of myeloid inflammation and cytokine expression in the brain, but the long-term course of neuroinflammation after sepsis remains unclear. Here, we utilize cecal ligation and puncture with greater than 80% survival as a model of sepsis. We found that sepsis survivor mice demonstrate deficits in extinction of conditioned fear, but no acquisition of fear conditioning, nearly two months after sepsis. These cognitive changes occur in the absence of neuronal loss or changes in synaptic density in the hippocampus. Sepsis also resulted in infiltration of monocytes and neutrophils into the CNS at least two weeks after sepsis in a CCR2 independent manner. Cellular inflammation is accompanied by long-term expression of pro-inflammatory cytokine and chemokine genes, including TNFα and CCR2 ligands, in whole brain homogenates. Gene expression analysis of microglia revealed that while microglia do express anti-microbial genes and damage-associated molecular pattern molecules of the S100A family of genes at least 2 weeks after sepsis, they do not express the cytokines observed in whole brain homogenates. Our results indicate that in a naturalistic model of infection, sepsis results in long-term neuroinflammation, and that this sustained inflammation is likely due to interactions among multiple cell types, including resident microglia and peripherally derived myeloid cells.

    Antihyperlipidemia or hypocholesterolaemic and antibacterial activities of red hot pepper and garlic are well known. To determine the effect of the dietary spices ingested to suppress blood lipids on the intestinal condition, we examined plasma lipid levels and cecal microflora in mice that were fed diets containing 19% (w/w) beef tallow and 2% red pepper Capsicum annuum var. conoides 'Takanotume' (RP) or garlic Allium sativum 'White' (GP) for 4-weeks. Plasma triacylglyceride level was suppressed by the spices. RP lowered cecal bacteroidaceae, a predominant bacterial group (from 9.4 to 9.0 log CFU/g), bifidobacteria (from 8.7 to 7.6 log CFU/g), and staphylococci. Although GP increased the cecal weight including their contents, significant differences were not shown in the cecal microflora. These results suggest that RP can affect the intestinal condition and host health through the disturbance of intestinal microflora.

    Full Text Available Abstract Background Salmonellosis is one of the most important bacterial food borne illnesses worldwide. A major source of infection for humans is consumption of chicken or egg products that have been contaminated with Salmonella enterica serotype Typhimurium, however our knowledge regarding colonization and persistence factors in the chicken is small. Results We compared intestinal and systemic colonization of 1-week-old White Leghorn chicks and Salmonella-resistant CBA/J mice during infection with Salmonella enterica serotype Typhimurium ATCC14028, one of the most commonly studied isolates. We also studied the distribution of wild type serotype Typhimurium ATCC14028 and an isogenic invA mutant during competitive infection in the cecum of 1-week-old White Leghorn chicks and 8-week-old CBA/J mice. We found that although the systemic levels of serotype Typhimurium in both infected animal models are low, infected mice have significant splenomegaly beginning at 15 days post infection. In the intestinal tract itself, the cecal contents are the major site for recovery of serotype Typhimurium in the cecum of 1-week-old chicks and Salmonella-resistant mice. Additionally we show that only a small minority of Salmonellae are intracellular in the cecal epithelium of both infected animal models, and while SPI-1 is important for successful infection in the murine model, it is important for association with the cecal epithelium of 1-week-old chicks. Finally, we show that in chicks infected with serotype Typhimurium at 1 week of age, the level of fecal shedding of this organism does not reflect the level of cecal colonization as it does in murine models. Conclusion In our study, we highlight important differences in systemic and intestinal colonization levels between chick and murine serotype Typhimurium infections, and provide evidence that suggests that the role of SPI-1 may not be the same during colonization of both animal models.

  20. Anthocyanins in Strawberry Polyphenolic Extract Enhance the Beneficial Effects of Diets with Fructooligosaccharides in the Rat Cecal Environment.

    Bartosz Fotschki

    Full Text Available The administration of fructooligosaccharides (FOS beneficially modulates gastrointestinal functions and may enhance the metabolism of polyphenols. However, different polyphenolic components in the diet may have different influences on the activities of the digestive enzymes and microbiota in the gastrointestinal tract. Therefore, a 4-week study of forty-eight male Wistar rats was conducted to investigate the physiological response of the rat cecal environment to diets without and with FOS that contained two different strawberry polyphenolic extracts, specifically EP (polyphenolic profile 60, 35, 5, and 0% ellagitannins, proanthocyanidins, flavonols, anthocyanins, respectively and EPA (polyphenolic profile: 50, 35, 6, and 9%, respectively. When combined with FOS, both extracts beneficially enhanced the acidification of the cecal digesta (P≤0.05 vs the groups without extracts, but the dietary combination of EPA and FOS elicited the greatest reduction in putrefactive short-chain fatty acid production and the lowest fecal β-glucuronidase activity in the cecum (P≤0.05 vs group EP. Moreover, the addition of dietary FOS elevated the metabolism of the examined strawberry extracts in the cecum and thereby increased the concentrations of the metabolites in the cecal digesta and urine (P≤0.05 vs the group with cellulose. Overall, both strawberry extracts modulated the effects of FOS in the gastrointestinal tract; however, the combination with EPA extract that contained anthocyanins exhibited greater beneficial effects in the lower gut environment than the EP extract.

    There is an increasing movement against use of antibiotic growth promoters in animal feed. Prebiotic supplementation is a potential alternative to enhance the host's natural defense through modulation of gut microbiota. In the present study, the effect of mannan oligosaccharide (MOS) and virginiamycin (VIRG) on cecal microbial ecology and intestinal morphology of broiler chickens raised under suboptimal conditions was evaluated. MOS and VIRG induced different bacterial community structures, as revealed by denaturing gradient gel electrophoresis of 16S rDNA. The antibiotic treatment reduced cecal microbial diversity while the community equitability increased. A higher bacterial diversity was observed in the cecum of MOS-supplemented birds. Quantitative polymerase chain reaction results indicated that MOS changed the cecal microbiota in favor of the Firmicutes population but not the Bacteroidetes population. No difference was observed in total bacterial counts among treatments. MOS promoted the growth of Lactobacillus spp. and Bifidobacterium spp. in the cecum and increased villus height and goblet cell numbers in the ileum and jejunum. These results provide a deeper insight into the microbial ecological changes after supplementation of MOS prebiotic in poultry diets.

    Full Text Available The gastrointestinal (GI bacteriome of poultry is important in host nutrition and health, but its diversity and composition remain poorly characterized. In this study we phylogenetically characterized the bacteriome in the cecal contents and ileal mucosa of chickens and turkeys using metagenomics empowered by pyrosequencing technique. >95% coverage of bacterial diversity was achieved except for the turkey ileal mucosa. Collectively, 3,401 and 125 operational taxonomy units (OTU, defined at a 0.03 phylogenetic distance in chicken, and 1,687 and 16 OTUs in turkey were identified from the cecal content and the ileal mucosa, respectively. Besides those previously reported, 39 and 50 additional genera of bacteria were identified in the chicken and turkey cecal bacteriome, respectively. Although the GI bacteriomes of the same region in both species exhibited greater similarity than the bacteriomes of different regions within each species, broiler chickens and turkeys harbor a distinct intestinal bacteriome. Such difference may suggest different dietary interventions for bacteriome modulation for enhanced nutrient utilization and gut health. The results may also be useful in developing prebiotics, probiotics, and analytical tools (e.g., phylochips. We also determined the variation in the number of OTUs and variability between two independent pyrosequencing runs and two data processing pipelines.

    Aim: This study was designed to elucidate the histoenzymic distribution of enzymes, i.e., phosphatases, oxidoreductases, dehydrogenases, and diaphorases in cecal lymphoid tissue during its development in the prenatal period. Materials and Methods: The study was conducted on cecum of 15 buffalo fetuses ranging from 16 cm curved crown-rump length (CVRL) (100 days) to 100 cm CVRL (full term). The fetuses were categorized into three groups based on their CVRL. Results: In Group I, the distribution of enzymes was uniformly weak in developing villi-like projections in cecum and completely absent from submucosa. In Group II, the enzymes showed a moderate to strong activity in epithelium lining tunica mucosa which progressively decreased as the fetus progresses toward late gestational age. However, the intense activity of enzymes was observed in developing lymphoid tissue in this group. In Group III, distribution of enzymes reduced in tunica mucosa of cecum with advancing age, whereas the intense activity was noticed in the developed lymphoid tissue complex. Conclusion: The distribution of enzymes was completely absent from submucosal region in cecum of Group I as there was no lymphoid tissue development at this age. In Group II, the enzymes showed a moderate to strong activity in epithelium lining tunica mucosa which progressively decreased toward late gestational age but an intense activity was observed in developing lymphoid tissue. In Group III, distribution of enzymes reduced in tunica mucosa with advancing age with intense activity noticed in the developed lymphoid tissue complex. PMID:27733804

    Hydrogen sulfide (H2S) is an endogenously produced gaseous messenger that participates in regulation of cardiovascular functions. This study evaluates the possible protective effect of H2S in cardiovascular dysfunction induced by cecal ligation and puncture (CLP) in rats. After 24 h of induction of CLP, heart rate (HR), mortality, cardiac and inflammation biomarkers (creatine kinase-MB (CK-MB) isozyme, cardiac troponin I (cTnI), C-reactive protein (CRP), and lactate dehydrogenase (LDH)), in vitro vascular reactivity, histopathological examination, and oxidative biomarkers (malondialdehyde (MDA), reduced glutathione (GSH), and superoxide dismutase (SOD)) were determined. CLP induced elevations in HR, mortality, serum CK-MB, cTnI, CRP, and LDH, in addition to impaired aortic contraction to potassium chloride and phenylephrine and relaxation to acetylcholine without affecting sodium nitroprusside responses. Moreover, CLP increased cardiac and aortic MDA and decreased SOD, without affecting GSH and caused a marked subserosal and interstitial inflammation in endocardium. Sodium hydrosulfide, but not the irreversible inhibitor of H2S synthesis dl-propargyl glycine, protected against CLP-induced changes in HR, mortality, cardiac and inflammatory biomarkers, oxidative stress, and myocardium histopathological changes without affecting vascular dysfunction. Our results confirm that H2S can attenuate CLP-induced cardiac, but not vascular, dysfunction possibly through its anti-inflammatory and antioxidant effects.

    In order to elucidate the significance and related mechanisms of microbial agents in modulating the growth of broilers, one-day-old Avian broilers were employed to investigate the effect of microbial agents on body weight, daily gain and feed efficiency at various stages. The birds in the experimental groups were given salmonella pullorum then fed with antibiotics to counteract it. The results showed that the average broiler weight of the oral microbial agent group at the age of 40 days was significantly increased by 16.58% from 1520g to 1772 g (P < 0.05). The feed conversion efficiency was decreased from 2.21 to 1.82 (P < 0.01). In the experimental group fed with microbial agents, microscopic observation revealed that the intestinal villi increased in number, length and orderliness. The intestinal wall became thickened. The glands in the intestine were developed, which would be beneficial to nutrient absorption. The effect of oral microbial agents was identical to that due to antibiotics. It was also observed that Lactobacillus dominated the cecal microorganisms in broilers.

    Full Text Available Background and Aim. The predisposing factors for prolonged cecal intubation time (CIT during colonoscopy have been well identified. However, the factors influencing CIT during retrograde SBE have not been addressed. The aim of this study was to determine the factors influencing CIT during retrograde SBE. Methods. We investigated patients who underwent retrograde SBE at a medical center from January 2011 to March 2014. The medical charts and SBE reports were reviewed. The patients’ characteristics and procedure-associated data were recorded. These data were analyzed with univariate analysis as well as multivariate logistic regression analysis to identify the possible predisposing factors. Results. We enrolled 66 patients into this study. The median CIT was 17.4 minutes. With univariate analysis, there was no statistical difference in age, sex, BMI, or history of abdominal surgery, except for bowel preparation (P=0.021. Multivariate logistic regression analysis showed that inadequate bowel preparation (odds ratio 30.2, 95% confidence interval 4.63–196.54; P<0.001 was the independent predisposing factors for prolonged CIT during retrograde SBE. Conclusions. For experienced endoscopist, inadequate bowel preparation was the independent predisposing factor for prolonged CIT during retrograde SBE.

    Fermentation metabolites of Diamond V Original XPC™ (XPC), a biological product derived from yeast fermentation, were evaluated for their ability to reduce the Salmonella Typhimurium population using an in vitro mixed anaerobic culture system containing cecal microbiota to simulate chicken hindgut conditions. Four different samples were prepared: anaerobic mixed culture containing (1) feed only, (2) cecal only (ceca were harvested from 42 days old broiler chickens), (3) feed and cecal contents, and (4) feed, cecal contents, and 1% XPC. Two experimental conditions were investigated: Group 1, in which the cecal content was added at the same time as a S. Typhimurium marker strain and Group 2, in which the cecal content was preincubated for 24 h prior to the inoculation with the S. Typhimurium marker strain. The mixed cultures were incubated anaerobically at 37°C, and the S. Typhimurium marker strain was enumerated at 0, 24, and 48 h. Analysis of short chain fatty acids was also conducted for 24 h. In the Group 1 experiment, adding XPC did not exhibit significant reduction of S. Typhimurium. However, the presence of XPC resulted in rapid reduction of S. Typhimurium in Group 2. S. Typhimurium was reduced from 6.81 log10 CFU/ml (0 h) to 3.73 log10 CFU/ml and 1.19 log10 CFU/ml after 24 and 48 h, respectively. These levels were also 2.47 log10 and 2.72 log10 lower than the S. Typhimurium level recovered from the control culture with feed and cecal contents, but without XPC. Based on these results, it appears that the ability of XPC to reduce S. Typhimurium requires the presence of the cecal microbiota. Short chain fatty acid analysis indicated that acetate and butyrate concentrations of cultures containing XPC were twofold greater than the control cultures by 24 h of anaerobic growth. Results from the present study suggest that dietary inclusion of XPC may influence cecal microbiota fermentation and has the potential to reduce Salmonella in the cecum

    Purpose To investigate which colonoscopy (CS) cases should be presided over by endoscopists in training, using factors including obesity and metabolic syndrome. Patients and methods Items investigated were sex, age, body mass index (BMI), waist circumference, hypertension, diabetes, hyperlipidemia, history of abdominal surgery (excluding colectomy), colon diverticulosis, prescription of antithrombotic agents, and quality of bowel preparation. Expert physicians were defined as those with at least 9 years of endoscopy experience; all other physicians were defined as being in training. In a retrospective analysis, cases in which a physician in training reached the cecum within 15 minutes without requiring the involvement of the supervising physician were defined as eligible cases over which a physician in training should preside, while other cases were defined as non-eligible. Results Overall, 813 CS cases were analyzed. Males (P<0.0001), cases started by an expert physician (P<0.0001), cases of no fellow physician involvement (P<0.0001), and cases with good bowel preparation (P<0.0001) had significantly shorter cecal intubation times. Of the 562 cases presided over by a physician in training, 194 were deemed eligible and 368 non-eligible. The eligible cases had a higher proportion of males (P=0.017), younger age (P=0.033), higher BMI (P=0.034), and higher rates of hypertension (P=0.001) and good bowel preparation (P=0.001). In analysis by sex, males demonstrated significantly more eligible cases among younger patients (P=0.009) and those with good bowel preparation (P=0.008), while there were significantly more eligible cases among females with hypertension (P=0.004). Conclusion It may be useful to select CS cases for physicians considering sex, age, BMI, hypertension, and bowel preparation. PMID:28115863

    Full Text Available Sepsis and its complications are the leading causes of mortality in intensive care units, accounting for 10-50% of deaths. Intensive care unit survivors present long-term cognitive impairment, including alterations in memory, attention, concentration, and/or global loss of cognitive function. In the present study, we investigated behavioral alterations in sepsis-surviving rats. One hundred and ten male Wistar rats (3-4 months, 250-300 g were submitted to cecal ligation and puncture (CLP, and 44 were submitted to sham operation. Forty-four rats (40% survived after CLP, and all sham-operated animals survived and were used as control. Twenty animals of each group were used in the object recognition task (10 in short-term memory and 10 in long-term memory, 12 in the plus-maze test and 12 in the forced swimming test. Ten days after surgery, the animals were submitted individually to an object recognition task, plus-maze and forced swimming tests. A significant impairment of short- and long-term recognition memory was observed in the sepsis group (recognition index 0.75 vs 0.55 and 0.74 vs 0.51 for short- and long-term memory, respectively (P < 0.05. In the elevated plus-maze test no difference was observed between groups in any of the parameters assessed. In addition, sepsis survivors presented an increase in immobility time in the forced swimming test (180 vs 233 s, P < 0.05, suggesting the presence of depressive-like symptoms in these animals after recovery from sepsis. The present results demonstrated that rats surviving exposure to CLP, a classical sepsis model, presented recognition memory impairment and depressive-like symptoms but not anxiety-like behavior.

A Peutz–Jeghers polyp (PJP in a patient without pigmentation or a family history of the disease is called an isolated or solitary PJP. Individuals with PJS carry a very high risk of developing gastrointestinal (GI as well as extra-GI malignancies. This case report documents lesion multiplicity and their malignant potential in a young patient with PJS presenting in a serious condition for the first time.Case report: An 18-year-old female Egyptian patient was admitted with hematochezia and remarkable anemia. After appropriate resuscitation and consent, colonoscopic evaluation revealed seven pedunculated colonic polyps at the ascending and the transverse colon, and numerous variable-sized sessile polyps were scattered all over the colon. To establish hemostasis, endoscopic polypectomy for pedunculated polyps and argon plasma photocoagulation for the bleeding sessile polyps were performed. Histopathological examination revealed cecal adenocarcinoma in one specimen and two simultaneous in situ carcinoma at the transverse and the sigmoid colon in the mucosae of the excised histologically proven hamartomatous polyps. Additionally, one focal in situ carcinoma in the resected colon was detected.Conclusions: When considering the family history, serious GI neoplastic lesions may be unmasked in young patients with PJS who present with hematochezia, even in the absence of its characteristic mucocutaneous pigmented lesions. GI endoscopic surveillance programs should be adopted for diagnosed cases of PJS and their families. Genetic prenatal screening for early detection is the best option for

    Cecal ligation and puncture (CLP)-induced sepsis is a serious medical condition, caused by a severe systemic infection resulting in a systemic inflammatory response. Recent studies have suggested the therapeutic potential of donors of hydrogen sulfide (H2S), a novel endogenous gasotransmitter and biological mediator in various diseases. The aim of the present study was to assess the effect of H2S supplementation in sepsis, with special reference to its effect on the modulation of regional blood flow. We infused sodium hydrosulfide (NaHS), a compound that produces H2S in aqueous solution (1, 3, or 10 mg/kg/h, for 1 h at each dose level) in control rats or rats 24 h after CLP, and measured blood flow using fluorescent microspheres. In normal control animals, NaHS induced a characteristic redistribution of blood flow, and reduced cardiac, hepatic, and renal blood flow in a dose-dependent fashion. In contrast, in rats subjected to CLP, cardiac, hepatic, and renal blood flow was significantly reduced; infusion of NaHS (1 mg/kg/h and 3 mg/kg/h) significantly increased organ blood flow. In other words, the effect of H2S on regional blood flow is dependent on the status of the animals (i.e., a decrease in blood flow in normal controls, but an increase in blood flow in CLP). We have also evaluated the effect of delayed treatment with NaHS on organ dysfunction and the inflammatory response by treating the animals with NaHS (3 mg/kg) intraperitoneally (i.p.) at 24 h after the start of the CLP procedure; plasma levels of various cytokines and tissue indicators of inflammatory cell infiltration and oxidative stress were measured 6 h later. After 24 h of CLP, glomerular function was significantly impaired, as evidenced by markedly increased (over 4-fold over baseline) blood urea nitrogen and creatinine levels; this increase was also significantly reduced by treatment with NaHS. NaHS also attenuated the CLP-induced increases in malondialdehyde levels (an index of

    Prebiotics are defined as nondigestible food ingredients that can stimulate the growth of one or more beneficial bacteria in the gastrointestinal tract. The Biolex(®) MB40 is a commercial prebiotic that contains mannanoligosaccharides. The aims of this study were to evaluate the effects of prebiotic Biolex(®) MB40 on cecal microbiota of conventionally raised chickens using PCR-based denaturing gradient gel electrophoresis (DGGE) and assessing Salmonella prevalence. Chickens were randomly selected and distributed into three groups; a negative control (NC) and two treatment groups (T1 and T2). The NC group was fed a non-medicated feed, while the treatment groups were fed either T1 or T2, 0.05% antibiotic (BMD50) or 0.2% Biolex(®) MB40 respectively. During the study, cecal contents and bird feed were plated on selective media for Salmonella, yeast and mold prevalence analysis. Ten chickens from each group were randomly selected at 1, 2, 4 and 6 wk and ceca were extracted for DNA isolation for PCR-based DGGE. Also, short-chain fatty acids (SCFAs) were analyzed from collected cecal material by gas chromatography. Only 4.2% of the samples were Salmonella positive. Presence of class 1 integron from cecal material were analyzed by PCR and 97.5% of the cecal samples were positive for integron presence, but no class I integrons were detected in the Salmonella isolates. According to the PCR-based DGGE analysis, the T2 group exhibited a cecal microbial population pattern that was similar to the T1 group prior to wk 4 and the T2 group appeared to be almost identical with the NC group after wk 4 but T2 exhibited less Bacteroides rodentium prior to wk 4. Overall results showed that the commercial prebiotic, MB40 did not lead to a detectable reduction of Salmonella but the general frequency of Salmonella was minimal in all treatments. However, feeding an MB40 supplement did result in similar DGGE band patterns as the T1 group indicating that cecal microbiotia were potentially

    Full Text Available Abstract Background Obese patients display an exaggerated morbidity during sepsis. Since consumption of a western-style diet (WD is a major factor for obesity in the United States, the purpose of the present study was to examine the influence of chronic WD consumption on hepatic inflammation in mice made septic via cecal ligation and puncture (CLP. Feeding mice diets high in fat has been shown to enhance evidence of TLR signaling and this pathway also mediates the hepatic response to invading bacteria. Therefore, we hypothesized that the combined effects of sepsis and feeding WD on TRL-4 signaling would exacerbate hepatic inflammation. Male C57BL/6 mice were fed purified control diet (CD or WD that was enriched in butter fat (34.4% of calories for 3 weeks prior to CLP. Intravital microscopy was used to evaluate leukocyte adhesion in the hepatic microcirculation. To demonstrate the direct effect of saturated fatty acid on hepatocytes, C3A human hepatocytes were cultured in medium containing 100 μM palmitic acid (PA. Quantitative real-time PCR was used to assess mRNA expression of tumor necrosis factor-alpha (TNF-α, monocyte chemotactic protein-1 (MCP-1, intercellular adhesion molecule-1 (ICAM-1, toll-like receptor-4 (TLR-4 and interleukin-8 (IL-8. Results Feeding WD increased firm adhesion of leukocytes in the sinusoids and terminal hepatic venules by 8-fold six hours after CLP; the increase in platelet adhesion was similar to the response observed with leukocytes. Adhesion was accompanied by enhanced expression of TNF-α, MCP-1 and ICAM-1. Messenger RNA expression of TLR-4 was also exacerbated in the WD+CLP group. Exposure of C3A cells to PA up-regulated IL-8 and TLR-4 expression. In addition, PA stimulated the static adhesion of U937 monocytes to C3A cells, a phenomenon blocked by inclusion of an anti-TLR-4/MD2 antibody in the culture medium. Conclusions These findings indicate a link between obesity-enhanced susceptibility to sepsis and

    An experiment with 288 male (Ross 308) 1-d-old broilers was conducted to test the hypothesis that a coarse diet supplemented with butyric acid (BA) and fermentable carbohydrates (FC) improves performance of broilers with a poorly digestible protein source. The interaction effects of diet structure (fine or coarse), FC supplementation (with or without), and BA supplementation (with or without) in a poorly digestible diet based on rapeseed meal (RSM) were tested in a factorial arrangement of 8 (2×2×2) dietary treatments. The coarseness of the diet affected feed intake (FI) (Pcarbohydrate supplementation did not influence growth performance, gut development, or contents of total BCFA and total biogenic amines in the cecal digesta (P>0.05). Supplementation with FC, however, decreased the cecal concentration of spermine by approximately 31% compared with broilers fed diets without FC (P=0.002). In conclusion, feeding a coarse diet supplemented with BA improved performance of broilers fed a diet containing a poorly digestible protein source. The negative effects of a poorly digestible protein source can thus be partly counterbalanced by coarse grinding and BA supplementation in the diet.

    Full Text Available The objective of this experiment was to evaluate the effect of different rates of propolis alcoholic extract (PAE on the weight gain, carcass traits and cecal pH of growing rabbits. Forty White New Zealand rabbits were distributed in a completely randomized experimental design consisting of four treatments and ten replicates per treatment. The rabbits were allocated individually in wire cages containing a nipple drinker and a semi-automatic feeder. The treatments were: T1 = control, T2 = 1ml of ethanol, T3 = 0.8ml of PAE, and T4 = 1.5ml of PAE. Commercial feed and water were provided ad libitum to the animals, and the treatment with cereal alcohol and PAE was administered orally using a 2ml syringe. It was concluded that the addition of PAE to the rabbits’ feeding resulted in weight gain, carcass traits and cecal pH similar to those of animals which received the diets with ethanol without any addition, except for the paw weight, that was higher in the rabbits which were given PAE, and for the gastric system, that had a higher weight in the rabbits which received no addition to their diet.

    Afatoxin B1 (AFB1) is the most toxic form among the mycotoxins. Cytokines are important mediators of the immune system. T-cell subsets play a crucial role in cell-mediated immunity. The aim of present study was to evaluate the effects of dietary AFB1 on the cytokines expression and T-cell subsets in the cecal tonsil of broiler chickens throughout a 21-day experimental period. One hundred and fifty six one-day-old broiler chickens were randomly divided into control group (0 mg AFB1/kg feed) and AFB1 group (0.6 mg pure AFB1/kg feed). At 7, 14 and 21 days of age, the levels of seven cytokines (IL-2, IL-4, IL-6, IL-10, IL-17, IFN-γ and TNF-α) mRNA expression as well as the proportions of T-cell subsets (CD3+, CD3+CD4+, CD3+CD8+) by qRT-PCR and flow cytometry methods were assessed in the cecal tonsils. The levels of the seven cytokines mRNA expression and the percentages of T-cell subsets significantly decreased at 14 and 21 days of age in the AFB1 group compared with the control group. However, the CD4+/CD8+ ratio was not significantly changed. These results demonstrate that 0.6 mg/kg AFB1 dietary exposure reduced the levels of cytokines mRNA expression and the percentages of T-cell subsets in the cecal tonsils of broiler chickens, suggesting that the cell-mediated immunity of cecal tonsils might be impaired in broilers.

    Our hypothesis in this study was that in vitro disappearance of isoflavones from fecal or cecal contents of Golden Syrian hamsters paralleled the apparent absorption of these compounds, comparable with previous findings from in vitro human fecal incubations. Two studies were conducted to test this idea: one on in vitro fecal (study 1, n = 20/sex) and the other on in vitro cecal contents (study 2, n = 10/sex) ability to degrade isoflavones. According to HPLC analysis, urinary isoflavone excretion was significantly less by 2-4 fold in males compared with females in both studies. Fecal isoflavone excretion was not significantly different between sexes or isoflavones (study 1) and was genistein). Hamster in vitro cecal isoflavone degradation rate constants seemed to be analogous to human in vitro fecal isoflavone degradation rate constants for genistein and daidzein. The sex difference in isoflavone excretion in hamsters and the instability in glycitein excretion across studies coupled with the paucity of human data on this isoflavone deserve further investigation.

    The objective of this study was to evaluate effects of two commercially available probiotic additives, containing Bacillus spores, on carcass and meat characteristics, serum lipids and concentration of cecal volatile fatty acids of meat type chickens. Birds were fed regular corn-soy meal based feed (control), supplemented with additive A, containing 1.6 × 10(6) spores per gram of feed of Bacillus subtilis and Bacillus licheniformis (group A) or additive B, containing the same concentration of Bacillus cereus var. toyoi spores (group B). One hundred and twenty birds (20 per replicate) were slaughtered at the age of 55 days. Results showed that birds in group B had higher (p blood serum cholesterol profile. Both probiotics influenced the cecal fermentation, which was observed as decrease in cecal concentrations of propionic, butyric, n-butyric and n-valeric acids, but the differences compared to control group were statistically significant for group A only. It was established that probiotic additive B was more effective regarding carcass and meat part weights than additive A, however the animals from group B also had more abdominal fat and their meat had significantly higher conductivity than control group, which is not considered as beneficial.

    Preadministration of antioxidants such as pyrrolidine dithiocarbamate (PDTC) and phenyl N-tert-butyl nitrone (PBN) protects animals from lethality in sepsis models. However, the requirement of preadministration greatly diminishes the clinical significance of these studies. Although the synthetic antioxidant PBN has been shown to effectively protect rodents from lethality in endotoxemia (lipopolysaccharide [LPS] model), preliminary screening indicates that pre- or postadministration of PBN does not protect in the rat cecal ligation and puncture (CLP) model. We show in this report that in a rat CLP model, the administration of PBN (150 mg/kg, 30 min after CLP) followed by the antibiotic imipenem (IMP; 10 mg/kg, 1 h after CLP) significantly increased survival compared with other single treatment groups. Previously, we have shown that PBN's protection in a rat LPS model is mediated by the overproduction of the anti-inflammatory cytokine interleukin (IL)-10. We show in this study that the increase in survival found in the PBN + IMP-treated group was abrogated by immunoneutralization with anti-IL-10 antibody, indicating that endogenous IL-10 is an effective protective factor. Plasma LPS levels were shown to be elevated after imipenem treatment, and the increased LPS level could have assisted to overproduce endogenous IL-10, as in the case of the PBN-treated LPS model. Statistical analysis indicated that the increase of IL-10 in PBN + IMP-treated group at early time period has significant association to the improvement of survival.

    Sepsis can result in excessive and maladaptive inflammation that is responsible for more than 215,00 deaths per year in the United State alone. Current strategies for reducing the morbidity and mortality associated with sepsis rely on treatment of the syndrome rather than prophylaxis. We have been investigating a modified tetracycline, COL-3, which can be given prophylactically to patients at high risk for developing sepsis. Our group has shown that COL-3 is very effect at preventing the sequelae of sepsis if given before or immediately after injury in both rat and porcine sepsis models. In this study, we wanted to determine the "treatment window" for COL-3 after injury at which it remains protective. Sepsis was induced by cecal ligation and puncture (CLP). Rats were anesthetized and placed into five groups: CLP (n = 20) = CLP without COL-3, sham (n = 5) = surgery without CLP or COL-3, COL3@6h (n = 10) = COL-3 given by gavage 6 h after CLP, COL3@12h (n = 10) = COL-3 given by gavage 12 h after CLP, and COL3@24h (n = 20) = COL-3 given by gavage 24 h after CLP. COL-3 that was given at 6 and 12 h after CLP significantly improved survival as compared with the CLP and the CLP@24h groups. Improved survival was associated with a significant improvement in lung pathology assessed morphologically. These data suggest that COL-3 can be given up to 12 h after trauma and remain effective.

    Novel mechanisms of action and new chemical scaffolds are needed to rejuvenate antibacterial drug discovery, and riboswitch regulators of bacterial gene expression are a promising class of targets for the discovery of new leads. Herein, we report the characterization of 5-(3-(4-fluorophenyl)butyl)-7,8-dimethylpyrido[3,4-b]quinoxaline-1,3(2H,5H)-dione (5FDQD)-an analog of riboflavin that was designed to bind riboswitches that naturally recognize the essential coenzyme flavin mononucleotide (FMN) and regulate FMN and riboflavin homeostasis. In vitro, 5FDQD and FMN bind to and trigger the function of an FMN riboswitch with equipotent activity. MIC and time-kill studies demonstrated that 5FDQD has potent and rapidly bactericidal activity against Clostridium difficile. In C57BL/6 mice, 5FDQD completely prevented the onset of lethal antibiotic-induced C. difficile infection (CDI). Against a panel of bacteria representative of healthy bowel flora, the antibacterial selectivity of 5FDQD was superior to currently marketed CDI therapeutics, with very little activity against representative strains from the Bacteroides, Lactobacillus, Bifidobacterium, Actinomyces, and Prevotella genera. Accordingly, a single oral dose of 5FDQD caused less alteration of culturable cecal flora in mice than the comparators. Collectively, these data suggest that 5FDQD or closely related analogs could potentially provide a high rate of CDI cure with a low likelihood of infection recurrence. Future studies will seek to assess the role of FMN riboswitch binding to the mechanism of 5FDQD antibacterial action. In aggregate, our results indicate that riboswitch-binding antibacterial compounds can be discovered and optimized to exhibit activity profiles that merit preclinical and clinical development as potential antibacterial therapeutic agents.

    Nopal is a cactus plant widely consumed in Mexico that has been used in traditional medicine to aid in the treatment of type-2 diabetes. We previously showed that chronic consumption of dehydrated nopal ameliorated hepatic steatosis in obese (fa/fa) rats; however, description of the effects on other tissues is sparse. The aim of the present study was to investigate the effects of nopal cladode consumption on intestinal physiology, microbial community structure, adipose tissue, and serum biochemistry in diet-induced obese rats. Rats were fed either a normal fat (NF) diet or a HF diet containing 4% of dietary fiber from either nopal or cellulose for 6 weeks. Consumption of nopal counteracted HF-induced adiposity and adipocyte hypertrophy, and induced profound changes in intestinal physiology. Nopal consumption reduced biomarkers of intestinal inflammation (mRNA expression of IL-6) and oxidative stress (ROS), modfied gut microbiota composition, increasing microbial diversity and cecal fermentation (SCFA), and altered the serum metabolome. Interestingly, metabolomic analysis of dehydrated nopal revealed a high choline content, which appeared to generate high levels of serum betaine, that correlated negatively with hepatic triglyceride (TAG) levels. A parallel decrease in some of the taxa associated with the production of trimethylamine, suggest an increase in choline absorption and bioavailability with transformation to betaine. The latter may partially explain the previously observed effect of nopal on the development of hepatic steatosis. In conclusion, this study provides new evidence on the effects of nopal consumption on normal and HF-diet induced changes in the intestine, the liver and systemic metabolism. PMID:28196086

    Different attempts have been made to improve the health status of humans and animals by increasing the intestinal production of short-chain fatty acids (SCFA) derived from non-digestible carbohydrates fermentation. In this paper we investigate the in vitro production of short-chain fatty acids (SCFA) after addition of inulin, propionibacteria or a combination of both in an experimental model of mice cecal slurries. The development of bacterial genera which are usually stimulated by inulin addition was also investigated. According to our experimental data, acetic acid and butyric acids concentrations increased after incubation in slurries that had no supplements. By contrast, butyric acid concentrations remained in the basal value when supplements were used. Fermentation of only inulin did not increase the concentration of total SCFA. Propionibacterium acidipropionici CRL1198 improved the production of propionic acid in cecal slurries when it was added alone, but the effect was more noticeable in the combination with inulin. A modulation of the global fermentative activity of the cecal microbiota was evidenced by the increase on the ratio propionic acid/SCFA in supplementations with propionibacteria. Statistical analysis of data demonstrated that samples from homogenates with propionibacteria alone or combined with inulin belong to the same cluster. The presence of propionibacteria limited the growth of Bacteroides fragilis and Clostridium hystoliticum groups in slurries with and without inulin. The growth of Bifidobacterium was not modified and the stimulating effect of inulin on lactobacilli disappeared in the presence of propionibacteria. In conclusion, dairy propionibacteria are potential candidates to develop new functional foods helpful to ensure the intestinal production of SCFA during inulin supplementation and to control the overgrowth of bacteria belonging to Bacteroides and Clostridium genera.

    Background:The antagonistic actions of anticholinesterase drugs on non-depolarizing muscle relaxants are theoretically related to the activity ofacetylcholinesterase (AChE) in the neuromuscular junction (NMJ).However,till date the changes of AChE activity in the NMJ during sepsis have not been directly investigated.We aimed to investigate the effects of sepsis on the antagonistic actions ofneostigmine on rocuronium (Roc) and the underlying changes of AChE activity in the NMJ in a rat model of cecal ligation and puncture (CLP).Methods:A total of 28 male adult Sprague-Dawley rats were randomized to undergo a sham surgery (the sham group,n =12) or CLP (the septic group,n =16).After 24 h,the time-response curves of the antagonistic actions of 0.1 or 0.5 μmol/L of neostigmine on Roc (10 μmol/L)-depressed diaphragm twitch tension were measured.Meanwhile,the activity of AChE in the NMJ was detected using a modified Karnovsky and Roots method.The mRNA levels of the primary transcript and the type T transcript of AChE (AChET) in the diaphragm were determined by real-time reverse transcription-polymerase chain reaction.Results:Four of 16 rats in the septic group died within 24 h.The time-response curves of both two concentrations ofneostigmine in the septic group showed significant upward shifts from those in the sham group (P < 0.001 for 0.1 μmol/L;P =0.009 for 0.5 μmol/L).Meanwhile,the average optical density of AChE in the NMJ in the septic group was significantly lower than that in the sham group (0.517 ± 0.045 vs.1.047 ± 0.087,P < 0.001).The AChE and AChET mRNA expression levels in the septic group were significantly lower than those in the sham group (P =0.002 for AChE;P =0.00l for AChET).Conclusions:Sepsis strengthened the antagonistic actions ofneostigmine on Roc-depressed twitch tension of the diaphragm by inhibiting the activity of AChE in the NMJ.The reduced content of AChE might be one of the possible causes of the decreased AChE activity in the NMJ.

    Gluconic acid reaches the large intestine to stimulate lactic acid bacteria. However, the fermentation pattern of gluconic acid has yet to be elucidated. Accordingly, we examined the fermentation properties induced by gluconic acid in the pig cecal digesta in vitro. We also tested sorbitol and glucose, substrates for which the fermentation rate and patterns are known. The gluconic acid-utilizing bacteria were further isolated from pig cecal digesta and identified to examine the effect of gluconic acid on hind gut fermentation. Gluconic acid was fermented more slowly than were the other two substrates. Gluconic acid stimulated butyrate production; the butyrate molar percentage reached 26%, which is considered a high butyrate production. The majority of gluconic acid fermenters were identified as lactic acid bacteria, such as Lactobacillus reuteri and L. mucosae, and acid-utilizing bacteria, such as Megasphaera elsdenii and Mitsuokella multiacida. The gluconic acid fermented by lactic acid bacteria, and the lactate and acetate that were produced were used to form butyrate by acid-utilizing bacteria, such as M. elsdenii. Gluconic acid may be useful as a prebiotic to stimulate butyrate production in the large intestine.

    The effects of 2 levels of mannanoligosaccharide (MOS) in feed were compared with antibiotic growth promoters on growth performance, intestinal morphology, cecal and litter microbial populations, and carcass parameters in broilers raised in a sanitary environment. Dietary treatments included: 1) antibiotic growth promoter-free diet (control), 2) VIRG (diet 1 + 16.5 mg/kg of virginiamycin), 3) BACT (diet 1 + 55 mg/kg of bacitracin), 4) LMOS (diet 1 + 0.2% MOS), and 5) HMOS (diet 1 + 0.5% MOS). Birds were randomly assigned to 3 replicate pens/treatment (n = 55/pen). Body weight and feed intake were recorded weekly throughout 38 d. At d 14, 24, and 34, a 1-cm segment of duodenum, jejunum, and ileum was used in morphological analysis (n = 9 birds/d per treatment). At the same bird ages, cecal contents were assayed for lactobacilli, bifidobacteria, Salmonella, Campylobacter, and Escherichia coli, whereas litter was analyzed for Salmonella, Campylobacter, and E. coli. Carcass yields (breast fillet and tenders, thigh, drumstick, and wing) were determined at d 38. Body weight, feed conversion, and carcass yields did not differ among treatments. In contrast to birds fed VIRG or BACT, LMOS and HMOS consistently increased (P microbial ecology. But, there were no additional benefits of the higher MOS dosage.

    Two experiments were conducted to test the feeding value of fermented cottonseed meal (FCSM) in broilers. In experiment 1, 480 1-day-old male yellow-feathered broilers were allocated into 4 dietary treatments with 6 replicates (20 birds per replicate) to examine the effects of FCSM on the growth response of chickens. Experimental feeding was performed for 6 weeks in two phases (starter, days 0 to 21; finisher, days 22 to 42). FCSM was used at 0, 40, 80, and 120 g/kg levels to replace soybean meal in the basal diet. The dietary inclusion of 40 and 80 g/kg FCSM increased (quadratic (Q): pmicrobial populations, intestinal morphology, and digestive enzyme activity of broilers. The number of lactobacilli in the cecal digesta increased at day 21 (pamylase and protease at day 21, as well as protease at day 42. In conclusion, the appropriate inclusion of FCSM improves growth, cecal microflora, intestinal morphology, and digestive enzyme activity in yellow-feathered broilers.

    Full Text Available The effects of treatment with anaerobic cecal microflora (ACM and/or lactose and/or acetic acid on systemic and digestive tract of broiler chicks infection with Salmonella Typhimurium and S. Enteritidis were studied. ACM was used without previous bacterial identification. Treatment with ACM contributed to the resistance of broiler chicks to infection with Salmonella spp. The infections were more persistent in the cecum, rectum and crops in decreasing order of intensity. The infections were also self-limiting since treated and control lots presented similar infection rates at the end of the experiments. Alone or in combination with lactose, ACM reduced the colonization of the digestive tract of broiler chicks by S. Typhimurium and S. Enteritidis. The effect of the combination of ACM with lactose or acetic acid was not potentiated in terms of reduction of fecal excretion of Salmonella spp. Treatment with ACM reduced the amount of S. Typhimurium and S. Enteritidis in the feces. Alone or in combination with lactose, ACM reduced the cecal pH in treated birds. S. Enteritidis was much more invasive than S. Typhimurium and the use of ACM alone was more effective on the reduction of systemic infection. An explanation for the process of prevention of intestinal colonization with Salmonella spp. probably resides in the interrelationship of physiological, microbiological and immunological phenomena, as well as the variation in cecal pH.Estudaram-se os efeitos do tratamento de frangos com microbiota cecal anaeróbia (MCA isolada ou associada à lactose ou ao ácido acético, sobre a infecção sistêmica e do trato digestivo de aves por Salmonella Typhimurium e S.

    Five experiments were conducted to evaluate the effects of whole wheat, whole sorghum, or whole barley on nutrient digestibility, growth performance, and cecal short-chain fatty acid concentrations when supplemented primarily at the expense of corn in ground corn-soybean meal control diets. The first 4 experiments utilized New Hampshire x Columbian male chicks. In the first 2 experiments, feeding 5, 10, 15, or 20% whole wheat had no effect on growth performance at 21 d when compared with chicks fed the control diet. The third experiment tested 20, 35, and 50% whole wheat fed from 0 to 21 d of age and showed that a 50% whole wheat diet decreased (Pwhole sorghum reduced (Pwhole barley had similar weight gains to chicks fed a ground corn-soybean meal diet. The fifth experiment with commercial Ross x Ross male broiler chicks evaluated 10 and 20% whole sorghum or whole barley and 20 and 35% whole wheat. Growth at 21 d was unaffected by any dietary treatment. Feed efficiency was decreased (Pwhole wheat and improved (Pwhole barley. Feeding whole grains to chicks resulted in an increase in gizzard weight, even as early as 7 d, in all experiments. Chicks fed diets containing 10 to 20% whole wheat generally had increased MEn values at 3 to 4, 7, 14, and 21 d and also had increased amino acid digestibility at 21 d in one experiment. At 21 d, cecal pH and short-chain fatty acid concentrations in all experiments were unaffected by feeding whole grains to chicks. The results of this study indicated that feeding whole wheat, sorghum, or barley increased gizzard weight, and feeding 10 to 20% whole wheat may increase ME and amino acid digestibility.

    Diarrhea incidence in weaned pigs may be associated with the concentration of intestinal microbial metabolites (ammonia, amines, and VFA) that are influenced by dietary CP content. Three experiments were conducted to determine effects of a low-protein, AA-supplemented diet on ileal AA digestibility, growth performance, diarrhea incidence, and concentration of microbial metabolites in ileal and cecal digesta of pigs weaned at 14 d of age. In Exp. 1, 8 pigs fitted with a simple T-cannula at the distal ileum were assigned in a crossover design to 2 diets containing 24 or 20% CP using wheat, corn, full-fat soybeans, whey powder, fish meal, and blood plasma as the main ingredients. Supplemental AA were added to the diets to meet the AA standards according to the 1998 NRC recommendations. Chromic oxide was used as an indigestible marker. Diets were fed at 2.5 times the ME requirement for maintenance. The reduction of dietary CP decreased (P acid, isobutyric acid, isovaleric acid, total VFA, and putrescine concentrations by 28 to 39%. In Exp. 3, 32 pigs were assigned to 2 diets, similar to Exp. 1, according to a randomized complete block design. Pigs had free access to feed and water. Dietary CP content did not affect growth performance or fecal consistency scores during the 3-wk study, and diarrhea was not observed. The results of these experiments indicate that lowering the dietary CP content combined with supplementation of AA markedly reduced the production of potentially harmful microbial metabolites in cecal digesta of early-weaned pigs without affecting growth performance.

    Fermented Chlorella vulgaris was examined for its effects on growth performance, cecal microflora, tibia bone strength, and meat qualities in commercial Pekin ducks. A total of three hundred, day-old male Pekin ducks were divided into three groups with five replicates (n = 20 ducklings per replicate) and offered diets supplemented with commercial fermented C. vulgaris (CBT(®)) at the level of 0, 1,000 or 2,000 mg/kg, respectively for 6 wks. The final body weight was linearly (p = 0.001) increased as the addition of fermented C. vulgaris into diets increased. Similarly, dietary C. vulgaris linearly increased body weight gain (p = 0.001) and feed intake (p = 0.001) especially at the later days of the feeding trial. However, there was no C. vulgaris effect on feed efficiency. Relative weights of liver were significantly lowered by dietary fermented C. vulgaris (linear effect at p = 0.044). Dietary fermented C. vulgaris did not affect total microbes, lactic acid bacteria, and coliforms in cecal contents. Finally, meat quality parameters such as meat color (i.e., yellowness), shear force, pH, or water holding capacity were altered by adding fermented C. vulgaris into the diet. In our knowledge, this is the first report to show that dietary fermented C. vulgaris enhanced meat qualities of duck meats. In conclusion, our study indicates that dietary fermented C. vulgaris exerted benefits on productivity and can be employed as a novel, nutrition-based strategy to produce value-added duck meats.

    Text mining is a flexible technology that can be applied to numerous different tasks in biology and medicine. We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence. For this reason, we have developed the DISEASES resource, which integrates the results from text mining with manually curated disease-gene associations, cancer mutation data, and genome-wide association studies from existing databases...

    Full Text Available Foram avaliados 10 eqüinos da raça Manga Larga, machos, inteiros clinicamente sadios, submetidos à punção cecal percutânea. Analisou-se a resposta clínica, celular, bioquímica e microbiológica do líquido peritoneal por um período de 24 horas após a punção cecal, nos tempos T0, T6, T12 e T24. Foi observada elevação na freqüência respiratória em T6 e na temperatura retal entre T6 e T12. Decorridas 24 horas da punção cecal, ocorreu aumento na concentração de proteínas totais do líquido peritoneal e na atividade da fosfatase alcalina. Tanto a atividade da ALT quanto os níveis de hemoglobina apresentaram diminuição em T6. Não foram registradas alterações na celularidade do plasma ou do líquido peritoneal e obteve-se resultado negativo para a cultura microbiológica do líquido. Considerando a inexistência de efeitos adversos, além das poucas alterações descritas, conclui-se que a punção cecal percutânea é um procedimento seguro e factível, se praticada criteriosamente.

    Full Text Available Fluoride is an environmental and industrial pollutant that affects various organs in humans and animals. The cecal tonsil is an important component of the mucosal immune system and performs important and unique immune functions. In the present study, we investigated the effects of dietary high fluorine on the quantities of IgA+ B cells in the cecal tonsil by immunohistochemistry, and the immunoglobulin A (IgA, immunoglobulin G (IgG and immunoglobulin M (IgM contents in the cecal tonsil by ELISA. A total of 280 one-day-old avian broilers were divided into four groups and fed on a corn-soybean basal diet as control diet (fluorine 22.6 mg/kg or the same diet supplemented with 400, 800 and 1,200 mg/kg fluorine (high fluorine groups I, II and III in the form of sodium fluoride, respectively, throughout a 42-day experimental period. The results showed that the quantities of IgA+ B cells were lower (p < 0.05 or p < 0.01 and the IgA, IgG, and IgM contents were decreased (p < 0.05 or p < 0.01 in high fluorine groups II and III in comparison with those of control group. It was concluded that dietary fluorine, in the 800–1,200 mg/kg range, could reduce the numbers of the IgA+ B cells and immunoglobulin contents in the cecal tonsil, implying the local mucosal immune function was ultimately impacted in broilers.

    The present study was conducted to evaluate the effect of the dietary supplementation of Bacillus amyloliquefaciens-based direct-fed microbial (DFM) on growth performance, nutrient utilization, intestinal morphology and cecal microflora in broiler chickens. A total of two hundred and eighty eight 1-d-old Arbor Acres male broilers were randomly allocated to one of four experimental treatments in a completely randomized design. Each treatment was fed to eight replicate cages, with nine birds per cage. Dietary treatments were composed of an antibiotic-free basal diet (control), and the basal diet supplemented with either 15 mg/kg of virginiamycin as antibiotic growth promoter (AGP), 30 mg/kg of Bacillus amyloliquefaciens-based DFM (DFM 30) or 60 mg/kg of Bacillus amyloliquefaciens-based DFM (DFM 60). Experimental diets were fed in two phases: starter (d 1 to 21) and finisher (d 22 to 42). Growth performance, nutrient utilization, morphological parameters of the small intestine and cecal microbial populations were measured at the end of the starter (d 21) and finisher (d 42) phases. During the starter phase, DFM and virginiamycin supplementation improved the feed conversion ratio (FCR; pvirginiamycin and DFM significantly increased the total tract apparent digestibility of crude protein (CP), dry matter (DM) and gross energy during both starter and finisher phases (p<0.05) compared with the control group. On d 21, villus height, crypt depth and villus height to crypt depth ratio of duodenum, jejunum, and ileum were significantly increased for the birds fed with the DFM diets as compared with the control group (p<0.05). The DFM 30, DFM 60, and AGP groups decreased the Escherichia coli population in cecum at d 21 and d 42 compared with control group (p<0.01). In addition, the population of Lactobacillus was increased in DFM 30 and DFM 60 groups as compared with control and AGP groups (p<0.01). It can be concluded that Bacillus amyloliquefaciens-based DFM could be an

    Hydrogen sulphide is an endogenous inflammatory mediator produced by cystathionine-γ-lyase (CSE) in macrophages. To determine the role of H2S and macrophages in sepsis, we used small interference RNA (siRNA) to target the CSE gene and investigated its effect in a mouse model of sepsis. Cecal ligation puncture (CLP)-induced sepsis is characterized by increased levels of myeloperoxidase (MPO) activity, morphological changes in liver and pro-inflammatory cytokines and chemokines in the liver and lung. SiRNA treatment attenuated inflammation in the liver and lungs of mice following CLP-induced sepsis. Liver MPO activity increased in CLP-induced sepsis and treatment with siRNA significantly reduced this. Similarly, lung MPO activity increased following induction of sepsis with CLP while siRNA treatment significantly reduced MPO activity. Liver and lung cytokine and chemokine levels in CLP-induced sepsis reduced following treatment with siRNA. These findings show a crucial pro-inflammatory role for H2S synthesized by CSE in macrophages in sepsis and suggest CSE gene silencing with siRNA as a potential therapeutic approach for this condition.

    An experiment was conducted to determine the effects of dietary fructooligosaccharides(FOS),compared with direct-fed microbial bacteria (DFM),and zinc bacitracin ,on cecal microbial populations and performance of broiler Chickens. One hundred and ninety-two broilers (Avian) were randomly assigned to four groups,with four replicates of 12 birds each. The control group was fed with the basal diet,without any drug additive. FOS,DFM and zine bacitracin was respectively added to the basal diet at the level of 1.5% ,800 mg@kg-1 and 300 mg@ kg-1 to form the experimental diets. Body weight ,feed intake and feed efficiency were measured weekly. The feeding trial started at 1 d and ended at 21 d. At day 14 and day 21 ,four broilers per group were killed and cecum waa taken to determined microflors and pH. The results showed that dietary FOS increased bifidobactrial concentration by 1. 75-fold( P <0. 05) at 14 d of age and 1.45-fold( P <0. 05) at 21 d of age compared with control. FOS had no effect on concnetrations of E. coli and pH. There were no dietary effects of FOS,DFM,and zinc bacitracin on weight gain,feed intake,feed conversion( P >0. 05).

    An experiment was conducted to investigate the supplementation of direct-fed microbials (DFM) as an alternative to antibiotics on growth performance, immune response, cecal microbial population, and ileal morphology of broiler chickens. A total of 800 one-day-old male broiler chicks (Ross × Ross) were randomly allotted to 4 dietary treatments with 4 replicate pens per treatment (50 birds/replicate pen). The 4 dietary treatments fed for 35 d were a corn-soybean meal basal diet (control); control plus 0.1% virginiamycin, as an antibiotic growth promoter (AGP); control plus 0.1% direct-fed microbials that contained Lactobacillus reuteri (DFM 1); and control plus 0.1% direct-fed microbials that contained a mixture of L. reuteri, Bacillus subtilis, and Saccharomyces cerevisiae (DFM 2). Results showed that dietary AGP and DFM supplementation significantly increased (P chickens fed DFM and AGP. The ileal villus height, and width and total thickness of muscularis externa were significantly increased when birds were fed DFM compared with AGP and control. These results indicate that the dietary supplementation of DFM increases the growth performance of birds at an early age, stimulates the immune response, decreases the number of E. coli, and improves the ileal morphology of broiler chickens. Thus, DFM that contained a mixture of several beneficial microorganisms could be a viable alternative to antibiotics in the broiler diets.

    The pathophysiology of sepsis-associated encephalopathy (SAE) is complex and remains incompletely elucidated. Dysregulated reactive oxygen species (ROS) production and mitochondrial-mediated necrotic-apoptotic pathway have been proposed as part of the pathogenesis. The present study aimed at analyzing the preventive effect of the free radical scavenger edaravone on sepsis-induced brain alterations. Sepsis was induced by cecal ligation and puncture (CLP) and the mice were divided into three groups-CLP vehicle (CLPV), CLP and edaravone (MCI-186, 3-methyl-1-phenyl-2-pyrazolin-5-one) (CLPE), and sham-operated (Sham). Mice in CLPV and CLPE were injected with saline or edaravone intraperitoneally at a dose of 10 mg/kg twice daily. The treatments were initiated 4 days prior to the surgical procedure. Mortality, histological changes, electron microscopy (EM), and expression of Bcl-2 family genes (Bcl-2 and Bax) were analyzed in selected brain regions. CLPE showed significant improvement in survival compared with CLPV 18 h postinduction of sepsis (P free radical scavenger edavarone reduces mortality of septic mice and protects against sepsis-induced neuronal cell death.

    This experiment was conducted to investigate the efficacy of Lactobacillus acidophilus, Bacillus subtilis, and Clostridium butyricum supplementation in broilers. A total of 400 one-day-old mixed sex Ross 308 broilers with an initial average BW of 46 ± 0.5 g were randomly allotted into 4 treatments with 5 replicate pens per treatment and 20 broilers in each pen for 35 d. Dietary treatments were (1) an antibiotic-free diet (CON), (2) CON + 5 mg/kg of avilamycin, (3) CON + 1 × 10(5) cfu of multistrain probiotics/kg of diet (P1), and (4) CON + 2 × 10(5) cfu of multistrain probiotics/kg of diet (P2). Broilers fed the P1 and P2 diets had greater BW gain than broilers fed the CON diet during d 22 to 35 (P = 0.01) and overall (P = 0.02). Feed conversion ratios in P1 and P2 were decreased (P = 0.03) compared with that in CON from d 22 to 35. Ileal digestibility of most essential amino acids, with the exception of His and Phe, were increased (P growth performance, ileal amino acids digestibility, and humoral immunity. Furthermore, the probiotics decreased the cecal numbers of E. coli and decreased the NH3 content of excreta.

    Full Text Available Sepsis is a systemic inflammatory response syndrome caused by an infection and remains as a major challenge in health care. Many studies have reported that pioglitazone may display anti-inflammatory effects. This study was designed to evaluate the effect of subchronic treatment with pioglitazone on high-grade septic mice survival and nitrergic system involvement. Diffused sepsis was induced by cecal ligation and puncture (CLP surgery in male NMRI mice (20-30 g. Pioglitazone (5,10 and 20 mg/kg was administered by gavage daily for 5 days prior to surgery. Nitric oxide involvement was assessed by sub-chronic administration of a non-selective nitric oxide synthase inhibitor, L-NAME and a selective inducible nitric oxide synthase inhibitor, aminoguanidine. TNF-α  and IL-1β plasma levels were measured by ELISA. Pioglitazone (10 and 20 mg/kg significantly improved survival rate in septic mice. The chronic intraperitoneally co-administration of L-NAME (0.5 mg/kg, daily or aminoguanidine (1 mg/kg, daily with a daily dose of pioglitazone, 5 mg/kg, significantly increased the survival rate. This survival improving effect was accompanied by a significant reduction in pro-inflammatory cytokines TNF-α and IL-1β plasma levels. In conclusion, sub-chronic pioglitazone treatment can improve survival in mouse sepsis model by CLP. Inhibition of nitric oxide release, probably through inducible nitric oxide synthase at least in part is responsible for this effect. Suppression of TNF-α and IL-1β could be another mechanism in pioglitazone-induced survival improving effect in septic mice.

A total of 250 male broiler chicks was randomly housed into 25 floor pens. Five dietary treatments with five replicates of 10 chicks each (n=50 chicks/treatment. A corn and soybean meal based diet was used as the control diet (NC. The experimental diets were formulated by mixing the basal diet either with antibiotics (10 ppm; PC or fermented garlic (FG at the concentrations of 0.1% (FG1, 0.3% (FG3 or 0.5% (FG5 in diets. Daily weight gain, feed intake, and feed:gain ratio were not affected by any of the dietary treatments. Average daily gain on day 21 linearly increased (p= 0.024 with increasing FG levels. The relative weight of the bursa of Fabricius showed a progressive decline with increasing the FG levels. Jejunal villus height was not influenced by dietary treatments. Villus width linearly decreased as FG levels increased (p= 0.17. Jejunal crypt depth was significantly lower (p< 0.05 in the FG1 and FG3 groups compared with the NC group. Villus height:crypt depth ratio linearly increased (p= 0.018 with increasing FG levels. The population of cecal microflora was not altered by dietary treatments. Broiler chickens fed the FG5 diet exhibited (p< 0.05 higher blood levels of total protein and cholesterol compared with those fed the NC diet. Collectively, the results show that dietary FG marginally affected growth performance, especially during the first days rearing, improved intestinal morphology, and altered blood characteristics of broiler chickens.

The aim of this work was to investigate the effect of prophylactic treatment with the hydroalcoholic crude extract (HCE) of C. ambrosioides and its hexanic fraction (HEX) on the control of bacterial growth, the activation of phagocytes and the control of the systemic inflammatory response in a sepsis experimental model. Animals were divided into three groups (n = 5/group): Control, which received only NaCl 0.9% solution; HCE, which received the crude extract; and HEX, which received the HEX of the extract. The animals received saline, HCE or HEX (5 mg/kg), subcutaneously (SC), 6 h before cecal ligation and puncture (CLP). Twelve hours after the CLP, the blood was collected to measure the serum cytokines and the animals were killed for the evaluation of colony-forming units (CFUs), cellular influx, and activation of phagocytes in the peritoneal cavity, measured by the secretion of hydrogen peroxide and nitric oxide production. The results showed that only HEX treatment inhibited bacterial growth in the peritoneum and inflammatory cellular influx, especially influx of macrophages and neutrophils. However, HCE and HEX treatments increased ex vivo hydrogen peroxide secretion and nitric oxide production by phagocytes and decreased the pro-inflammatory cytokines in the serum, indicating a systemic anti-inflammatory effect of both. In conclusion, C. ambrosioides treatment decreases bacterial growth likely by activation of phagocytes and, in parallel, ameliorates the general state of mice by reducing the systemic inflammatory response usually observed in sepsis.

    Sepsis is a serious medical condition that is characterized by a whole-body inflammatory state and the presence of a known or suspected infection. Amiodarone is a class III antiarrhythmic agent, a multichannel blocker (Ca++, Na+, and K+), and a noncompetitive α- and β-adrenergic blocker in cardiac cells. The present study aimed to determine whether amiodarone was protective against experimentally induced cecal ligation and puncture sepsis in rat lung tissue. The relationship between its probable protective effect and antioxidant/anticytokine action biochemically and histopathologically was also examined. Five groups of rats were used, each composed of 20 rats: (1) the sham-operated control group; (2) the CLP group; (3) the 25-mg/kg amiodarone-treated control healthy group; (4) the 50-mg/kg amiodarone-treated CLP group; and (5) the 50-mg/kg amiodarone-treated CLP group. A CLP polymicrobial sepsis model was applied to the rats. All groups were sacrificed 16 h later, and lung and blood samples were analyzed histopathologically and biochemically. Twenty-five and 50 mg/kg amiodarone decreased the level of interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in serum and 8-iso-prostaglandin F2α level in lung tissue. They increased the activities of superoxide dismutase and levels of total glutathione in lung tissues of rats. Histopathological scores and examinations were in accordance with the biochemical results. Histopathological analysis revealed significant differences in inflammation scores between the sepsis group and the other groups. The CLP + amiodarone 50 mg/kg group had the lowest inflammation score among CLP groups. Our results indicate that administration of amiodarone prevented oxidative stress and cytokine action and protected lung tissue during sepsis cascade.

    The purpose of this study was to assess the protective effect of senegenin on acute lung injury (ALI) in rats induced by sepsis. Rat ALI model was reproduced by cecal ligation and puncture (CLP). All rats were randomly divided into five groups: group 1 (control), group 2 (CLP), group 3 (CLP + senegenin 15 mg/kg), group 4 (CLP + senegenin 30 mg/kg), and group 5 (CLP + senegenin 60 mg/kg). CLP + senegenin groups received senegenin by gavage daily for consecutive 5 days, respectively, while the mice in control and CLP groups were given an equivalent volume of saline. We detected the lung wet/dry weight ratios and the histopathology of the lung. The levels of lung tissue myeloperoxidase (MPO), malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione (GSH) were determined. Meanwhile, the nuclear factor-kappa B (NF-κB) activation, tumor necrosis factor-alpha (TNF-α), and interleukin-1β (IL-1β) levels were studied. The results demonstrated that senegenin treatment significantly attenuated CLP-induced lung injury, including reduction of lung wet/dry weight ratio, protein leak, infiltration of leukocytes, and MPO activity. In addition, senegenin markedly decreased MDA content and increased SOD activity and GSH level. Serum levels of TNF-α and IL-1β were also decreased by senegenin administration. Furthermore, senegenin administration inhibited the nuclear translocation of NF-κB in the lungs. These findings indicate that senegenin exerts protective effects on CLP-induced septic rats. Senegenin may be a potential therapeutic agent against sepsis.

Salmonella Heidelberg has been isolated and reported from poultry and poultry products in Brazil since 1962, whereas Salmonella Enteritidis (SE has only emerged as a serious problem in poultry and public health since 1993. These strains of Salmonella can cause intestinal problems in newly hatched chicks, and infection may persist until adulthood. Upon slaughter of chickens, Salmonella can contaminate carcasses, a condition that poses a threat to human health. The aim of this study was to compare the fecal excretion of Salmonella Enteritidis and Salmonella Heidelberg in newly hatched chicks (orally inoculated with 10(5ufc/mL each until 20 days of age. In addition, the ratio of cecal villus height:crypt depth (morphometry and liver and cecum cell counts was analyzed in chicks ranging from 0 to 3 days of age and infected with these two Salmonella strains. One hundred seventeen chicks were separated into one of three experimental groups: a control group, an SE-infected group and an SH-infected group. Eight chicks per group were euthanized at 6, 12 and 72 hours post-inoculation (pi to allow for Salmonella isolation from the liver and cecum and for the collection of the cecum for villi and crypt analysis. Other birds were allowed to mature to 20 days of age and cloacal swabs were taken at 2, 6, 13 and 20 days pi to compare the fecal excretion of inoculated strains. The Salmonella Enteritidis group had a higher number of cells excreted during the trial. Both strains were isolated from the liver and cecum by 6h pi. At 12h pi the Salmonella Heidelberg group had high cell counts in the cecum. No difference was found in liver cell counts. Both strains showed lower villus height:crypt depth ratio than the control group post-infection.

    Full Text Available Abstract Background Neutrophil infiltration is one of the critical cellular components of an inflammatory response during peritonitis. The adhesion molecules, P-selectin and intercellular adhesion molecule (ICAM-1, mediate neutrophil-endothelial cell interactions and the subsequent neutrophil transendothelial migration during the inflammatory response. Despite very strong preclinical data, recent clinical trials failed to show a protective effect of anti-adhesion therapy, suggesting that the length of injury might be a critical factor in neutrophil infiltration. Therefore, the objective of this study was to determine the role of P-selectin and ICAM-1 in neutrophil infiltration into the peritoneal cavity during early and late phases of peritonitis. Methods Peritonitis was induced in both male wild-type and P-selectin/ICAM-1 double deficient (P/I null mice by cecal ligation-puncture (CLP. Peripheral blood and peritoneal lavage were collected at 6 and 24 hours after CLP. The total leukocyte and neutrophil contents were determined, and neutrophils were identified with the aid of in situ immunohistochemical staining. Comparisons between groups were made by applying ANOVA and student t-test analysis. Results CLP induced a severe inflammatory response associated with a significant leukopenia in both wild-type and P/I null mice. Additionally, CLP caused a significant neutrophil infiltration into the peritoneal cavity that was detected in both groups of mice. However, neutrophil infiltration in the P/I null mice at 6 hours of CLP was significantly lower than the corresponding wild-type mice, which reached a similar magnitude at 24 hours of CLP. In contrast, in peritonitis induced by intraperitoneal inoculation of 2% glycogen, no significant difference in neutrophil infiltration was observed between the P/I null and wild-type mice at 6 hours of peritonitis. Conclusions The data suggest that alternative adhesion pathway(s independent of P-selectin and ICAM

    Full Text Available This study was aimed to investigate changes in the number and distribution of lymphocytes in the mucosa associated lymphoid tissues (MALT of digestive tract (proventriculus, duodenum, jejunum, ileum, cecum and cecal tonsils and respiratory system (lungs of chicken infected by Infectious Bursal Disease Virus (IBDV. Samples were divided into two groups; IBDV infected group (21, 24 and 30 days old and control group (non infected birds; 21 days old. Haematoxylin and eosin stained slides were prepared for microscopic studies to observe the distribution and the number of lymphocytes in the mucosa of the digestive tract and respiratory system. Lymphocytes were significantly (P<0.05 lower in proventriculus, duodenum, jejunum, ileum, cecum, cecal tonsils and lungs of IBDV infected chickens than the control. Moreover, the reduction in lymphocytes number was maximum in duodenum and cecal tonsils, while minimal in lungs. Depletion of lymphocyte was mainly in the lamina propria and the core of the villi and depletion increased with the advance of age of IBDV infected chicken. These results demonstrate that IBDV destroys the lymphocytes of the MALT and suppresses the immunity.

  6. Phylum Level Change in the Cecal and Fecal Gut Communities of Rats Fed Diets Containing Different Fermentable Substrates Supports a Role for Nitrogen as a Factor Contributing to Community Structure

    Full Text Available Fermentation differs between the proximal and distal gut but little is known regarding how the bacterial communities differ or how they are influenced by diet. In order to investigate this, we compared community diversity in the cecum and feces of rats by 16S rRNA gene content and DNA shot gun metagenomics after feeding purified diets containing different fermentable substrates. Gut community composition was dependent on the source of fermentable substrate included in the diet. Cecal communities were dominated by Firmicutes, and contained a higher abundance of Lachnospiraceae compared to feces. In feces, community structure was shifted by varying degrees depending on diet towards the Bacteroidetes, although this change was not always evident from 16S rRNA gene data. Multi-dimensional scaling analysis (PCoA comparing cecal and fecal metagenomes grouped by location within the gut rather than by diet, suggesting that factors in addition to substrate were important for community change in the distal gut. Differentially abundant genes in each environment supported this shift away from the Firmicutes in the cecum (e.g., motility towards the Bacteroidetes in feces (e.g., Bacteroidales transposons. We suggest that this phylum level change reflects a shift to ammonia as the primary source of nitrogen used to support continued microbial growth in the distal gut.

    Full Text Available The present study was carried out to evaluate the in situ degradation of dry matter (DM, neutral detergent fiber (NDF and crude protein (CP in roughages by the in situ caecal digestion technique in horses. The roughages evaluated were: Lucerne hay (Medicago sativa, peanut (Arachis pintoi cv. Amarillo, desmodio(Desmodium ovalifolium, stylo (Stylosanthes guianensis cv. Mineirão, pigeon pea (Cajanus cajan, lime-yellow pea (Macrotyloma axillare and coastcross hay (Cynodon dactylon cv. coastcross. The assay was conducted in a complete randomized design with seven roughages and three replications. One mare with a cannula fitted in the caecum was used, fed diet consisting of coastcross hay (80% and concentrate (20% at 2.0% BW, four times a day. Nylon 6.5 × 20 cm bags were used with 45 μ/pore, containing 5.2 g DM/bag, inserting 3 or 4 bags in the caecum at the times of 2, 4, 6, 8, 12, 24 and 48 hours incubation. The caecum in situ degradability parameters of nutrients were obtained by Ørskov model. The DM degradability parameters of all the roughages were significant. There was no fit to the model for pigeon pea for CP and NDF and desmodio. Peanut, stylo and lime-yellow pea presented larger potentially degradable DM with values of 53, 46.5 and 40%, respectively, and higher values for the soluble fraction of 20, 21, 28.6%, with high degradability rates of 10.36, 20.26 and 14.8% h-1. Higher NDF degradation rates were observed in these foodstuffs with values of 9.1 and 11.3, 11.2% h-1, high potentially degradable fraction with values of 55, 51.8 and 47.2%, and greater CP degradation at 48 hours with values of 87, 95, and 94.8%.

    We investigated the potential protective effects of montelukast (MLK) on cecal ligation and puncture (CLP)-induced tissue injury in vital organs - liver, heart, kidneys, and especially lungs - through inhibition of the proinflammatory cytokine response and the generation of reactive oxygen species (ROS) in rats. The rat groups were (1) a 10-mg/kg MLK-treated CLP group; (2) a 20-mg/kg MLK-treated CLP group; (3) a 20-mg/kg MLK-treated, sham-operated group; (4) a CLP control group; and (5) a sham-operated control group. MLK treatment significantly decreased proinflammatory (tumor necrosis factor-alpha, interleukin-6) cytokine levels following CLP. The lipid peroxide level increased in the lung, heart, liver, and kidney tissues after CLP-induced sepsis, and myeloperoxidase activity increased in the lung, heart, and liver tissues. MLK attenuated this elevation in all tissues except the kidney, dose dependently. The glutathione levels and superoxide dismutase activity were significantly increased in the lung, liver, and kidney tissues after MLK treatment. MLK treatment after CLP also potentially reduced mortality. The lung and kidney tissues were the most protected by MLK under sepsis conditions. We can suggest that MLK reverses the systemic inflammatory reaction to polymicrobial sepsis and thereby reduces multiple organ failure.

    We wanted to determine the usefulness of the computed tomography (CT) findings for making the diagnosis between periappendiceal inflammation (PAI) with appendicitis and pelvic inflammatory disease (PID) for the women presenting with right lower quadrant pain. We retrospectively analyzed the CT findings of 83 women with right lower quadrant pain: PAI in 36 and PID in 47 patients. We reviewed the CT images, including the appendiceal diameter and the enhancing wall thickening, the cecal thickening, the location of the appendix, thickening of the right anterior renal fascia, abscess, mesenteric fatty infiltration, ascites, heterogeneous uterine enhancement and paralytic ileus. Statistical analysis was performed by using the t-test for the diameter of appendix, and the x{sup 2} test or Fisher's exact test for the CT findings. The mean diameter of the appendix was 11.0 {+-} 3.4 mm for the PAI subjects and it was 6.7 {+-} 2.0 mm for the PID subjects ({rho} < 0.0001). Wall thickening of the appendix was more commonly detected in PAI (25 subjects, 69%) than in PID (15 subjects, 32%) ({rho} = 0.0007). Thickening of the right anterior renal fascia was more commonly detected in PAI (18 subjects, 50%) than in PID (7 subjects, 15%). Cecal thickening, ascitis, heterogeneous uterine enhancement and paralytic ileus were not significantly different between PAI and PID. Abscess and mesenteric fatty infiltration were more frequently detected in the RLQ and in the abdomen or pelvic cavity in PAI and PID, respectively ({rho} < 0.05). There was no significant difference in the distribution of ascites between the diseases. The CT findings of the appendiceal diameter, enhancing wall thickening and thickening of the right anterior renal fascia are useful for making the diagnosis of PAI. The abdominal and pelvic distributions of abscess and mesenteric fatty infiltration are highly suggestive findings of PID.

    Objective To study the protective effects of isoflurane postcondition on acute lung injury (ALI) induced by cecal ligation and perforation (CLP) in rats. Methods A total of 48 male Sprague-Dawley rats were randomly divided into 4 groups (n = 12): normal group, without any treatment; sham operation group, with incision and closure of abdomen; CLP group, the CLP model was used to induce ALI; and isoflurane group, rats were anesthetized with 1.4% isoflurane at 4 h after CLP modeling for 2 h. Then 6 rats in each group were randomly killed by decapitation 6 h and 24 h after pretreatment. Blood samples of abdominal aorta were taken for arterial blood gas analysis. The tissues of left lung were taken for the determination of lung wet/dry (W/D) ratio. Tumor necrosis factor-a (TNF-α) and interleukin-6 (IL-6) levels were measured with blood sample of heart. Histopathological changes of the right lung and the expression of nuclear factor (NF)-KB were observed by H-E staining and immunohistochemical staining, respectively. Results There were no significant differences in arterial oxygen partial pressure (paO2), the ratio of W/D or serum concentrations of TNF-α and IL-6 between sham operation group and normal group (P>0.05). The paO2 in CLP group and isoflurane group was significantly lower than that in the normal group, while the ratio of W/D and serum concentrations of TNF-a and IL-6 in CLP group and isoflurane group were significantly higher than those in the normal group (P<0. 05). There were significant differences in above mentioned parameters between isoflurane group and CLP group (P<0. 05). There was no obvious lung injury in normal group or sham operation group. The rats in CLP group suffered more serious lung injury as compared with isoflurane group, and the lung injury at 24 h after precondition was much severe than that at 6 h after precondition. The cells with NF-KB expression were occasionally seen in normal group and sham operation group, while a large number

    This experiment was conducted to determine the effects of dietary fiber source and crude fiber ( CF) level on nutrient digestibility, intestinal digestive enzyme activities and cecal microbial diversity of meat rabbits. Six diets were formulated according to a two-factor experiment design based on isonitrogenous and isocaloric, one factor was fiber source ( alfalfa hay meal and rice husk meal) , and another was CF level ( 12%, 14% and 16%) . A total of 144 Hyla growing rabbits with the age of 70 to 80 days and average body weight of ( 2 002 ± 77) g were selected and randomly allocated in individual cages for six groups of 4 replicates containing six rab-bits per replicate. The feeding trial lasted for 4 weeks. Digestion experiment was conducted by the method of total fecal collection at the end of feeding trial. Afterwards, rabbits were slaughtered, and intestinal contents were sampled and stored for digestive enzyme activities and cecal microbial diversity determination. The results showed as follows:1) meat rabbits fed diets with the alfalfa hay meal as fiber source had significantly higher dry matter ( DM) , CF, acid detergent fiber ( ADF) and acid detergent lignin ( ADL) digestibility compared with meat rabbits fed diets with the rice husk meal as fiber source ( P0.05) , but meat rabbits fed diets with alfalfa hay meal as fiber source had the significantly higher cecal flora species evenness than that of meat rabbits fed diets with rice husk meal as fiber source ( P0.05),但苜蓿草粉组的盲肠菌群均衡指数极显著高于稻壳粉组( P<0.01)。 CF水平对盲肠菌群丰富度和香农指数有显著影响( P<0.05),其中16%CF水平组的数值均为最高。综上所述,在本试验条件下:1)苜蓿草粉组肉兔DM、CF、ADF、ADL 的消化率及盲肠菌群均衡指数显著或极显著高于稻壳粉组,但十二指肠胰蛋白酶活性极显著低于稻壳粉组。2)饲粮CF水平为12%时肉兔的ADE和各主要营养物质的消化率最

Method Complex microecological preparation was extracted from caecum flora of SPF chickens which were excluded from the possibility of Salmonella infection. The preparation was sprayed on eggs at 19 days ( when they pecking the shells) and 21 days ( when they pecking fully out of shells) of hatching, respectively. Salmonella in the excrement or its antibodies in the blood were monitored and the survival rate and production performance were recorded and analyzed. Result The inoculated chicken no longer needed antibiotics up to 12 days after birth; Their survival rate, weight and feed intake were slightly higher compared with the control group. A better feed reward could be observed. No Salmonella in the excrement or its antibodies in the blood could be observed after the chickens were fed for 12, 24 or 35 days. There was no Salmonella infection during the growth of these chickens. Conclusion Salmonella infection in broilers can be prevented with SPF chicken cecal probiotics complex instead of antibiotics.

  1. Butyrate enhances disease resistance of chickens by inducing antimicrobial host defense peptide gene expression.

    Directory of Open Access Journals (Sweden)

    Lakshmi T Sunkara

    Full Text Available Host defense peptides (HDPs constitute a large group of natural broad-spectrum antimicrobials and an important first line of immunity in virtually all forms of life. Specific augmentation of synthesis of endogenous HDPs may represent a promising antibiotic-alternative approach to disease control. In this study, we tested the hypothesis that exogenous administration of butyrate, a major type of short-chain fatty acids derived from bacterial fermentation of undigested dietary fiber, is capable of inducing HDPs and enhancing disease resistance in chickens. We have found that butyrate is a potent inducer of several, but not all, chicken HDPs in HD11 macrophages as well as in primary monocytes, bone marrow cells, and jejuna and cecal explants. In addition, butyrate treatment enhanced the antibacterial activity of chicken monocytes against Salmonella enteritidis, with a minimum impact on inflammatory cytokine production, phagocytosis, and oxidative burst capacities of the cells. Furthermore, feed supplementation with 0.1% butyrate led to a significant increase in HDP gene expression in the intestinal tract of chickens. More importantly, such a feeding strategy resulted in a nearly 10-fold reduction in the bacterial titer in the cecum following experimental infections with S. enteritidis. Collectively, the results indicated that butyrate-induced synthesis of endogenous HDPs is a phylogenetically conserved mechanism of innate host defense shared by mammals and aves, and that dietary supplementation of butyrate has potential for further development as a convenient antibiotic-alternative strategy to enhance host innate immunity and disease resistance.

    The purpose of this study was to explore the effects of nitrogen-free diets on cecal microflora and endogenous amino acid basal losses of broilers aged 14 and 35 days. A total of 308 Male Ross broiler chickens, aged 10 and 31 days, respectively, were chosen and randomly assigned into two dietary treatments, in which one was fed a conventional diet and the other was fed a nitrogen-free diet for 4 days. Every treatment contained five replicates with 12 chickens on day 10 and 6 chickens on day 31 per replicate. The results showed that endogenous basal losses of most amino acids determined by excreta-based assay were significantly higher than those determined by ileum digesta-based assay in broilers aged 14 and 35 days (P0. 05) , but the concentrations of butyric acid (P< 0.01) , isobutyric acid (P< 0.05) and valeric acid (P < 0. 05) in cecum digesta of broilers were significantly decreased and propionic acid concentration was significantly increased (P <0. 01) by the nitrogen-free diet compared with the conventional diet. On day 35, compared with conventional diet group, cecal digesta weight of broilers in the nitrogen-free diet group was significantly increased, and the concentrations of ammoniacal nitrogen, acetic acid, isobutyric acid, valeric acid and isovaleric acid were significantly decreased (P<0.01). In conclusion, endogenous basal losses of most amino acids measured by excreta-based assay are higher than those measured by ileal digesta-based assay when broilers are fed the nitrogen-free diet. Some predominant species of cecal microflora should change after broilers are fed the nitrogen-free diet for 4 days.

  13. Celiac disease

    Full Text Available Abstract Celiac disease is a chronic intestinal disease caused by intolerance to gluten. It is characterized by immune-mediated enteropathy, associated with maldigestion and malabsorption of most nutrients and vitamins. In predisposed individuals, the ingestion of gluten-containing food such as wheat and rye induces a flat jejunal mucosa with infiltration of lymphocytes. The main symptoms are: stomach pain, gas, and bloating, diarrhea, weight loss, anemia, edema, bone or joint pain. Prevalence for clinically overt celiac disease varies from 1:270 in Finland to 1:5000 in North America. Since celiac disease can be asymptomatic, most subjects are not diagnosed or they can present with atypical symptoms. Furthermore, severe inflammation of the small bowel can be present without any gastrointestinal symptoms. The diagnosis should be made early since celiac disease causes growth retardation in untreated children and atypical symptoms like infertility or neurological symptoms. Diagnosis requires endoscopy with jejunal biopsy. In addition, tissue-transglutaminase antibodies are important to confirm the diagnosis since there are other diseases which can mimic celiac disease. The exact cause of celiac disease is unknown but is thought to be primarily immune mediated (tissue-transglutaminase autoantigen; often the disease is inherited. Management consists in life long withdrawal of dietary gluten, which leads to significant clinical and histological improvement. However, complete normalization of histology can take years.

    Full Text Available Celiac disease is a multysystemic autoimmune disease induced by gluten in wheat, barley and rye. It is characterized by polygenic predisposition, high prevalence (1%, widely heterogeneous expression and frequent association with other autoimmune diseases, selective deficit of IgA and Down, Turner and Williams syndrome. The basis of the disease and the key finding in its diagnostics is symptomatic or asymptomatic inflammation of the small intestinal mucosa which resolves by gluten-free diet. Therefore, the basis of the treatment involves elimination diet, so that the disorder, if timely recognized and adequately treated, also characterizes excellent prognosis.

    Full Text Available Celiac disease is a small intestine disease caused by the immunological response to gluten, a component of wheat, rye and barley. The worldwide prevalence of celiac disease ranges between 0.2% and 2.2 %. The clinical features of celiac disease includes diarrhea, steatorrhea, flatulence, abdominal pain and weight loss. The asymptomatic type of celiac disease is characterized by soft or normally shaped stool, weakness, lassitude and moderate weight loss. In children, celiac disease usually arises between the first and the third year of age, with diarrhea, flatulence and low weight. The malabsorption in small intestine causes many extaintestinal manifestations, such us anemia, bone abnormalities, hemorrhage and neuropathy. Celiac disease is diagnosed by histological examination of tissue samples taken by duodenum due gastroscopy and by the detection of certain antibodies in blood (anti-GL-IgG, anti-GL-IgA, ΕΜΑ-IgA και anti-tTg-IgA. The only therapeutic approach to celiac disease is a gluten-free diet and, if it is necessary, the administration of iron, folic acid, calcium and vitamins (K, B12. The prognosis of celiac disease is excellent, if there is an early diagnosis and the patient keeps for life a gluten free diet.

    Full Text Available Celiac disease also known as gluten-sensitive enteropathy is characterized by intestinal mucosal damage and malabsorption from dietary intake of wheat, rye or barley. Symptoms may appear with introduction of cereal in the first 3 years of life. A second peak in symptoms occurs in adults during the third or forth decade and even as late as eight decade of life. The prevalence of this disease is approximately 1 in 250 adults. The disease is more prevalent in Ireland as high as 1 in 120 adults. The disorder occurs in Arab, Hispanics, Israeli Jews, Iranian and European but is rare in Chinese and African American. To have celiac disease the patient should have the celiac disease genetic markers as HLA DQ 2 and HLA DQ 8. Patient with celiac disease may have 95 per cent for DQ 2 and the rest is by DQ 8. Someone may have the genetic marker and never develops the disease. In general 50 percent with markers may develop celiac disease. To develop the disease the gene needs to become activated. This may happen with a viral or bacterial infection, a surgery, delivery, accident, or psychological stress. After activation of gene cause the tight junction to opens with the release of Zonulin This results in passage of gluten through the tight junction and formation of multiple antibodies and autoimmune disease. This also allows entrance of other proteins and development of multiple food allergies. As a result is shortening, flattening of intestinal villi resulting in food, vitamins and minerals malabsorption.

    Pompe's disease, glycogen-storage disease type II, and acid maltase deficiency are alternative names for the same metabolic disorder. It is a pan-ethnic autosomal recessive trait characterised by acid alpha-glucosidase deficiency leading to lysosomal glycogen storage. Pompe's disease is also regarded as a muscular disorder, but the generalised storage of glycogen causes more than mobility and respiratory problems. The clinical spectrum is continuous and broad. First symptoms can present in infants, children, and adults. Cardiac hypertrophy is a key feature of classic infantile Pompe's disease. For a long time, there was no means to stop disease progression, but the approval of enzyme replacement therapy has substantially changed the prospects for patients. With this new development, the disease is now among the small but increasing number of lysosomal storage disorders, for which treatment has become a reality. This review is meant to raise general awareness, to present and discuss the latest insights in disease pathophysiology, and to draw attention to new developments about diagnosis and care. We also discuss the developments that led to the approval of enzyme replacement therapy with recombinant human alpha-glucosidase from Chinese hamster ovary cells (alglucosidase alfa) by the US Food and Drug Administration and European Medicines Agency in 2006, and review clinical practice.

    Crohn\\'s disease is a disorder mediated by T lymphocytes which arises in genetically susceptible individuals as a result of a breakdown in the regulatory constraints on mucosal immune responses to enteric bacteria. Regulation of immune reactivity to enteric antigens has improved understanding of the pathophysiological mechanisms of Crohn\\'s disease, and has expanded therapeutic options for patients with this disorder. Disease heterogeneity is probable, with various underlying defects associated with a similar pathophysiological outcome. Although most conventional drug treatments are directed at modification of host response, therapeutic manipulation of the enteric flora is becoming a realistic option.

    Behçet's disease (BD) is a chronic relapsing and remitting vasculitis of unknown aetiology. It has the capacity to affect almost all organ systems because of its potential to involve both arteries and veins of all sizes, resulting in significant organ-threatening morbidity and mortality. Traditionally known as the 'silk road' disease, it has a worldwide occurrence. The aetiopathological mechanisms of disease development in BD remain poorly understood, but genome wide studies show human leukocyte antigen and non-human leukocyte antigen associations. Environmental influences and genetic factors may have a role in the aetiopathogenetic mechanisms that lead to development of the disease, indicating the autoimmune and auto-inflammatory nature of BD. The evidence base for treatment is limited but new knowledge is emerging and current treatment options range from symptomatic treatment, through to non-biological and biological immunosuppressive drugs, to cover the spectrum of clinical manifestations.

Their incidence is low, however the public health challenges derived from their transmissibility, especially due to the appearance of a variant of Creutzfeldt-Jakob disease (vCJD) confers them a preferential place among health care authority concerns. The evolution of data from the European surveillance systems suggests a generalized underdiagnosis of prion diseases and casts doubts about their ability to detect a possible second wave of atypical vCJD, especially if their clinical-pathological characteristics change. Recent data also challenge the feasibility of a subclassification of prion diseases according to their genetic-molecular features

In fact, it is the most common tick-borne infectious disease in the northern hemisphere. In Spain it is transmitted by Ixodes ricinus ticks and Borrelia garinii is the genoespecies of B. burgdorferi s.l. mostly involved in our area. LD is known as "the last great imitator" due to the broad clinical spectrum that may cause. Except in the case of erythema migrans (pathognomonic feature of the disease), the remaining clinical manifestations should be confirmed using microbiological tests. This review is intended to provide readers a current vision of the etiology, epidemiology, clinical manifestations, laboratory diagnosis and treatment of Lyme disease in our environment. Controversial aspects arising from the use of non-validated microbiological tests that are being used without scientific rigor are highlighted.

    Full Text Available Hirayama’s disease, also known as Monomelic Amyotrophy (MMA, juvenile non-progressive amyotrophy, Sobue disease. It is rare and benign condition. It is a focal, lower motor neuron type of disorder, which occurs mainly in young males. Age of onset, it is first seen most commonly in people in their second and third decades. Geographically, it is seen most commonly in Asian countries like India and Japan. Cause of this disease is unknown in most cases. MRI of cervical spine in flexion is the investigation of choice, which will reveal the cardinal features of Hirayama disease. CASE REPORT 20 years old male came with the complaints of tremors of both hands more of right hand and weakness and wasting of right hand, which is slowly progressive for past 6 months. Lower limbs had no abnormality with normal deep tendon reflexes. On examination, there was wasting and weakness of hypothenar and interosseous muscles of right hand. MRI showed thinning of cord from C5 to C7 level. Proximal epidural fat and tiny flow voids with anterior migration of the posterior dural layer at C5-7 level on flexion MRI. Based on these features a diagnosis of focal amyotrophy was made. A cervical collar was prescribed and patient is under regular follow-up. CONCLUSION Hirayama disease is a rare self-limiting disease. Early diagnosis is necessary as the use of a simple cervical collar which will prevent neck flexion, has been shown to stop the progression.

    Full Text Available Intussusception is the telescoping of a proximal bowel wall into the lumen of a distal segment. Although common in children, it is still a rare entity in adults and usually occurs secondarily to an underlying malignant neoplasia. Intussusception is relatively rare in adults. Here is reported the case of a 40-year-old woman with extensive colo-colonic intussuception of the right colon caused by a giant polypoid tumor that turned out to be a leiomyoma. The patient was successfully treated by reduction of the intussusception and then immediate hemicolectomy. [Arch Clin Exp Surg 2016; 5(3.000: 177-179

    Full Text Available Abstract Diverticulum of the cecum is a rare, benign, generally asymptomatic lesion that manifests itself only following inflammatory or hemorrhagic complications. Most patients with inflammation of a solitary diverticulum of the cecum present with abdominal pain that is indistinguishable from acute appendicitis. The optimal management of this condition is still controversial, ranging from conservative antibiotic treatment to aggressive resection. We describe four cases that presented with symptoms suggestive of appendicitis, but were found at operation to have an inflamed solitary diverticulum.

    Behcet's disease (BD) is a systemic disorder of recurrent acute inflammation, characterized by major symptoms of oral aphthous ulcers, uveitis, skin lesions and genital ulcers. Involvement of intestines, vessels, and central nervous system (CNS) sometimes leads to a poor prognosis. Patients with BD are known to distribute along the ancient Silk Road. The incidence is relatively higher from eastern Asia to the Mediterranean area as roughly 1-10 patients in 10,000 people, whereas only 1-2 patients in 1,000,000 people in UK and North America. Although etiology of the disease is still unknown, high prevalence of HLA-B51, increased expression of heat shock protein 60 and Th1 dominant immune responses in the patients are considered important in its pathogenesis. Non-infectious neutrophil activation and infection with Streptococcus sanguis and herpes simplex virus would also be associated. Because BD lacks any pathognomonic symptoms and laboratory findings, the diagnosis relies largely upon the criteria proposed by the International Study Group for Behcet's disease in 1990. In Japan, the diagnosis was also made according to the Japanese criteria revised in 1987. Recently, the Behcet's Disease Research Committee of Japan again revised the Japanese criteria in 2003 to avoid overdiagnosis. The new Japanese criteria are introduced in this review. Differential diagnosis excluding Sweet's disease, pemphigus, erythema nodosum and Crohn's disease is important, and positive laboratory data for pathergy test, prick test for dead Streptococci and HLA-B51 are emphasized to make appropriate diagnosis in these criteria. Pathological findings of the disease-affected site such as erythematous nodosum is also stressed. Treatment for the disease has been chosen according to the clinical symptoms. Non-steroidal anti-inflammatory drugs, immunosuppressants, corticosteroids and colchicine are basically introduced. Recently, effects of interferon-alpha/beta, anti-tumor necrosis factor antibody

    Full Text Available Abstract Dent's disease is a renal tubular disorder characterized by manifestations of proximal tubule dysfunction, including low-molecular-weight proteinuria, hypercalciuria, nephrolithiasis, nephrocalcinosis, and progressive renal failure. These features are generally found in males only, and may be present in early childhood, whereas female carriers may show a milder phenotype. Prevalence is unknown; the disorder has been reported in around 250 families to date. Complications such as rickets or osteomalacia may occur. The disease is caused by mutations in either the CLCN5 (Dent disease 1 or OCRL1 (Dent disease 2 genes that are located on chromosome Xp11.22 and Xq25, respectively. CLCN5 encodes the electrogenic Cl-/H+ exchanger ClC-5, which belongs to the CLC family of Cl- channels/transporters. OCRL1 encodes a phosphatidylinositol bisphosphate (PIP2 5-phosphatase and mutations are also associated with Lowe Syndrome. The phenotype of Dent's disease is explained by the predominant expression of ClC-5 in the proximal tubule segments of the kidney. No genotype-phenotype correlation has been described thus far, and there is considerable intra-familial variability in disease severity. A few patients with Dent's disease do not harbour mutations in CLCN5 and OCRL1, pointing to the involvement of other genes. Diagnosis is based on the presence of all three of the following criteria: low-molecular-weight proteinuria, hypercalciuria and at least one of the following: nephrocalcinosis, kidney stones, hematuria, hypophosphatemia or renal insufficiency. Molecular genetic testing confirms the diagnosis. The differential diagnosis includes other causes of generalized dysfunction of the proximal tubules (renal Fanconi syndrome, hereditary, acquired, or caused by exogenous substances. Antenatal diagnosis and pre-implantation genetic testing is not advised. The care of patients with Dent's disease is supportive, focusing on the treatment of hypercalciuria and

  5. Asymptomatic De Novo Inflammatory Bowel Disease Late After Liver Transplantation for Primary Sclerosing Cholangitis: A Case Report.

    2015-11-01

    Guidelines recommend colonoscopy screening for possible asymptomatic inflammatory bowel disease (IBD) in all patients diagnosed with primary sclerosing cholangitis (PSC). PSC-IBD warrants regular dysplasia-surveillance colonoscopy. However, no consensus exists regarding follow-up colonoscopy in PSC patients without IBD who remain asymptomatic. We describe a 43-year-old female who had undergone liver transplantation (LT) due to advanced PSC. Previous colonoscopies had been normal. The post-transplantation course was uneventful, with no rejections and signs of PSC recurrence. Immunosuppression was by tacrolimus monotherapy. She was asymptomatic with normal inflammation markers. A protocol colonoscopy, performed as general dysplasia surveillance 8 years post-transplantation, revealed mucopurulent-covered small superficial ulcerations and erythema diffusely distributed from the cecal to sigmoid colon with intervening normal mucosa and rectal sparing. Histologic examination showed patchy chronic colitis with crypt architectural distortion and mild-moderate inflammation activity. Infection samples were negative. Findings complied with de novo IBD, type unclassified. In conclusion, the link between PSC and clinically silent IBD may manifest after the PSC diagnosis and even several years after LT. Given the increased colorectal cancer risk associated with PSC, IBD, and LT, repeat colonoscopy might be warranted in PSC patients without IBD at initial assessment, and also after LT.

    Full Text Available Prion diseases are neurodegenerative illnesses due to the accumulation of small infectious pathogens containing protein but apparently lacking nucleic acid, which have long incubation periods and progress inexorably once clinical symptoms appear. Prions are uniquely resistant to a number of normal decontaminating procedures. The prionopathies [Kuru, Creutzfeldt-Jakob disease (CJD and its variants, Gerstmann-Sträussler-Scheinker (GSS syndrome and fatal familial insomnia (FFI] result from accumulation of abnormal isoforms of the prion protein in the brains of normal animals on both neuronal and non-neuronal cells. The accumulation of this protein or fragments of it in neurons leads to apoptosis and cell death. There is a strong link between mutations in the gene encoding the normal prion protein in humans (PRNP - located on the short arm of chromosome 20 – and forms of prion disease with a familial predisposition (familial CJD, GSS, FFI. Clinically a prionopathy should be suspected in any case of a fast progressing dementia with ataxia, myoclonus, or in individuals with pathological insomnia associated with dysautonomia. Magnetic resonance imaging, identification of the 14-3-3 protein in the cerebrospinal fluid, tonsil biopsy and genetic studies have been used for in vivo diagnosis circumventing the need of brain biopsy. Histopathology, however, remains the only conclusive method to reach a confident diagnosis. Unfortunately, despite numerous treatment efforts, prionopathies remain short-lasting and fatal diseases.

    Full Text Available The first cases of meningococcal meningitis were described in Geneva in 1805 and in New England in 1806, the causative agent finally being identified by Anton Weichselbaum in 1887. The first meningococcal epidemics occurred in sub-Saharan Africa in the early 1900s and periodic outbreaks continue to occur worldwide today. Neisseria meningitidis colonizes the naso-oropharyngeal mucosa in approximately 10–20% of healthy individuals. When it invades the bloodstream, meningococcus has the potential to cause devastating disease. It can affect people of any age, but primarily infects children and adolescents. Meningococcemia classically follows an upper respiratory illness consisting of myalgias, fever, headache, and nausea. It can present as an indolent infection with rapid recovery or progress within a few hours into a fulminant illness affecting multiple organ systems. As such, meningococcemia is one of the important causes of sepsis. Prior to antibiotic therapy, the disease carried a 70% mortality rate. Despite advances in early diagnosis and treatment, 10–15% of affected patients die from the disease and another 10–20% are left with severe morbidities (neurologic disability, hearing loss, loss of a limb. Meningococcal disease remains a significant global health threat.

Dept Infect Dis, 1st Affili Hosp, Sch Med, Xi′an Jiaotong Univ , Xi′an 710061. Chin J Infect Dis 2007;25(3):152-153. Objective To investigate the relationship between the expression level of platelet membrane glycoprotein 133(GP Ⅲa, CD61) and the severity of disease in patients with hemorrhagic fever with renal syndrome(HFRS). Methods One hundred and four patients with HFRS and 30 healthy individuals were recruited. The percentage of CD61 positive platelets and the mean fluorescence intensities (MFI) of platelet membrane glycoprotein β3 were determined by flow cytometry (FCM). The 104 patients studied were divided into three groups based on their expression levels of platelet membrane glycoprotein β3 at oliguric phase. Clinical data and laboratory parameters in different groups were compared and analyzed. Results The expression levels of CD61 in patients with HFRS were significantly higher than those in control group, although no significant difference in the percentage of CD61 positive platelets between patients with HFRS and controls was detected. The MFI of CD61 expression in patients with HFRS at fever phase, oliguric phase and polyuric phase was 19. 75±2.57, 17.46±1.48 and 15. 55±0.60, respectively, which was significantly higher than that in control group (3. 20±0.12). The expression level of CD61 in patients with HFRS at oliguric phase was negatively correlated with platelet count and serum albumin(r=-0.637 and -0. 695. respectively) and positively correlated with white blood cell count, blood urea nitrogen, serum creatinine and alanine aminotransferase(r= 0.945, 0. 904, 0.956 and 0. 891, respectively).

    Celiac disease (CD) is a common autoimmune disorder,induced by the intake of gluten proteins present in wheat, barley and rye. Contrary to common belief,this disorder is a protean systemic disease, rather than merely a pure digestive alteration. CD is closely associated with genes that code HLA-Ⅱ antigens, mainly of DQ2 and DQ8 classes. Previously, it was considered to be a rare childhood disorder, but is actually considered a frequent condition, present at any age, which may have multiple complications. Tissue transglutaminase-2(tTG), appears to be an important component of this disease, both, in its pathogenesis and diagnosis. Active CD is characterized by intestinal and/or extra-intestinal symptoms, villous atrophy and crypt hyperplasia, and strongly positive tTG auto-antibodies. The duodenal biopsy is considered to be the "gold standard" for diagnosis, but its practice has significant limitations in its interpretation, especially in adults. Occasionally, it results in a false-negative because of patchy mucosal changes and the presence of mucosal villous atrophy is often more severe in the proximal jejunum, usually not reached by endoscopic biopsies. CD is associated with increased rates of several diseases, such as iron deficiency anemia, osteoporosis, dermatitis herpetiformis,several neurologic and endocrine diseases, persistent chronic hypertransami-nasemia of unknown origin,various types of cancer and other autoimmune disorders.Treatment of CD dictates a strict, life-long gluten-free diet, which results in remission for most individuals,although its effect on some associated extraintestinal manifestations remains to be established.

    2010-05-01

    Menkes disease (MD) is a lethal multisystemic disorder of copper metabolism. Progressive neurodegeneration and connective tissue disturbances, together with the peculiar 'kinky' hair are the main manifestations. MD is inherited as an X-linked recessive trait, and as expected the vast majority of patients are males. MD occurs due to mutations in the ATP7A gene and the vast majority of ATP7A mutations are intragenic mutations or partial gene deletions. ATP7A is an energy dependent transmembrane protein, which is involved in the delivery of copper to the secreted copper enzymes and in the export of surplus copper from cells. Severely affected MD patients die usually before the third year of life. A cure for the disease does not exist, but very early copper-histidine treatment may correct some of the neurological symptoms.

    Loudianos, G; Gitlin, J D

    2000-01-01

    Wilson's disease is an autosomal recessive disorder of copper metabolism resulting from the absence or dysfunction of a copper transporting P-type ATPase encoded on chromosome 13. This ATPase is expressed in hepatocytes where it is localized to the trans-Golgi network and transports copper into the secretory pathway for incorporation into ceruloplasmin and excretion into the bile. Under physiologic circumstances, biliary excretion represents the sole mechanism for copper excretion, and thus affected individuals have progressive copper accumulation in the liver. When the capacity for hepatic storage is exceeded, cell death ensues with copper release into the plasma, hemolysis, and tissue deposition. Presentation in childhood may include chronic hepatitis, asymptomatic cirrhosis, or acute liver failure. In young adults, neuropsychiatric symptoms predominate and include dystonia, tremor, personality changes, and cognitive impairments secondary to copper accumulation in the central nervous system. The laboratory diagnosis of Wilson's disease is confirmed by decreased serum ceruloplasmin, increased urinary copper content, and elevated hepatic copper concentration. Molecular genetic analysis is complex as more than 100 unique mutations have been identified and most individuals are compound heterozygotes. Copper chelation with penicillamine is an effective therapy in most patients and hepatic transplantation is curative in individuals presenting with irreversible liver failure. Elucidation of the molecular genetic basis of Wilson's disease has permitted new insights into the mechanisms of cellular copper homeostasis.

    Full Text Available Newcastle disease (ND, caused by virulent strains of Newcastle disease virus (NDV, is a highly contagious disease of birds that is responsible for heavy economic losses for the poultry industry worldwide. However, little is known about host-virus interactions in waterfowl, goose. In this study, we aim to characterize the host immune response in goose, based on the previous reports on the host response to NDV in chickens. Here, we evaluated viral replication and mRNA expression of 27 immune-related genes in 10 tissues of geese challenged with a genotype VIId NDV strain of goose origin (go/CH/LHLJ/1/06. The virus showed early replication, especially in digestive and immune tissues. The expression profiles showed up-regulation of Toll-like receptor (TLR1–3, 5, 7 and 15, avian β-defensin (AvBD 5–7, 10, 12 and 16, cytokines interleukin (IL-8, IL-18, IL-1β and interferon-γ, inducible NO synthase (iNOS, and MHC class I in some tissues of geese in response to NDV. In contrast, NDV infection suppressed expression of AvBD1 in cecal tonsil of geese. Moreover, we observed a highly positive correlation between viral replication and host mRNA expressions of TLR1-5 and 7, AvBD4-6, 10 and 12, all the cytokines measured, MHC class I, FAS ligand, and iNOS, mainly at 72 h post-infection. Taken together, these results demonstrated that NDV infection induces strong innate immune responses and intense inflammatory responses at early stage in goose which may associate with the viral pathogenesis.

    Full Text Available Susceptibility of ostriches (Struthio camelus to the Indonesian velogenic strain of Newcastle disease virus (NDV was evaluated by artificial infection . Twelve - 5 to 6 week old ostriches were divided into 3 groups each containing 4 birds . The first group was inoculated through respiratory system by dropping directly the virus solution into the nostrils, while the second group was inoculated through digestive system by dropping directly the virus solution into the oesophagus, with the dose of infection 106ELDSo (50%-embryo lethal dose per bird . Meanwhile, the third group was treated as uninfected control . All infected birds developed antibody responses, but only two inoculated birds from the first group and two inoculated birds from the second group developed clinical signs of Newcastle disease (ND, with no specific pathological alterations . Infected birds, either sicks or healthy, excreted the challenge viruses through the respiratory system and still be detected up to the end of this experiment, ie . 15 days post-inoculation . The challenge viruses can be re-isolated from the brain, trachea, lungs, heart, liver, spleen, kidneys, small intestine, cecal-tonsil, and proventriculus of the infected birds . This study concludes that: (1 the ostriches are susceptible to the infection of the Indonesian velogenic strain ofNDV; (2 all infected birds developed immune responses, but only half of them develops el jtigi aj i disease ; (3 the infected birds excreted the challenge viruses for a considerable long time which may play role as the Mginiseti.ce ofinfectron the other healthy ostriches ; and (4 the challenge viruses can be re-isolated from various organs of the birds . .

    Celiac disease is an immunologically mediated enteropathy of the small intestine, characterized by lifelong intolerance to the gliadin and related prolamines from wheat and other cereals, that occurs in genetically predisposed individuals. Symptoms result from structural damage to the mucosa of the small intestine, which may cause malabsorption with positive autoantibodies in the sera. Normal mucosal architecture is restored after the use of a gluten-free diet and the normalization of the autoantibodies. Villous atrophy and high levels of autoantibodies reappear when gluten is reintroduced into the diet (gluten challenge).

    Full Text Available A 17-year-old male, who gave up his favorite sport cricket and started playing football, presented with one-year history of slowly progressive atrophic weakness of forearms and hands. Neurological examination showed weak and wasted arms, forearms and hand but no evidence of pyramidal tract, spinothalmic tract and posterior column lesions. Plain cervical spine radiographs showed no abnormal findings. Cervical magnetic resonance imaging (MRI showed asymmetric cord atrophy; images obtained with neck flexed showed the anterior shifting of the posterior wall of the lower cervical dural sac resulting in cord compression. These findings suggest Hirayama disease, a kind of cervical myelopathy related to the flexion movements of the neck.

    The exposition aims, is to review the pathophysiological mechanisms of bone marrow involvement and the patterns of marrow infiltration by Gaucher cells. We have reviewed the different methods of assessment of bone marrow infiltration and its temporal development. Qualitative methods include simple radiography, magnetic resonance imaging (MRI), computed tomography (CT) and radioisotope. The simple radiography is the basic element, but its sensitivity is limited and only allows for assessing changes and trabecular bone remodeling MRI allows us to appreciate the bone marrow infiltration, detection of complications and response to therapy. Radioisotopes can contribute to the differential diagnosis of osteomyelitis and bone crises. Among the quantitative methods are the QCSI (quantitative chemical shift imaging) and the dual-energy X-ray absorptiometry (DEXA), as well as new quantitative techniques of CT, MRI and ultrasound densitometry. The QCSI performed an assessment of fat content of bone marrow in the spine. DEXA quantifies bone density by measuring the attenuation coefficient. The semiquantitative methods have various "scores" to establish criteria for generalized bone disease endpoints of disease progression and response to therapy.

    To characterize the clinicopathologic features of recently described genotypes of Newcastle disease virus (NDV), 1 representative strain of genotype XIV and 2 of genotype XVII, all isolated from West Africa, were used to infect groups of ten 4-week-old specific pathogen-free chickens. The pathobiology of these 3 strains was compared to a South African NDV strain classified within genotype VII. All chickens infected with the 4 viruses died or were euthanized by day 4 postinfection due to the severity of clinical signs. Gross and histologic lesions in all infected chickens included extensive necrosis of lymphoid tissues (thymus, spleen, bursa of Fabricius, cecal tonsils, gut-associated lymphoid tissue), gastrointestinal necrosis and hemorrhages, and severe hemorrhagic conjunctivitis. Immunohistochemical staining revealed systemic viral distribution, and the most intense staining was in the lymphoid organs. Results demonstrate that the 3 West African strains from the previously uncharacterized genotypes XIV and XVII are typical velogenic viscerotropic NDV strains with lesions similar to the South African strain. Under experimental conditions, QV4 and LaSota NDV vaccine strains successfully protected chickens from morbidity and mortality against the genotype VII and one genotype XVII NDV strain, with no significant differences in the amount of virus shed when 2 vaccine schemes were compared.

    2013-01-01

    In advanced Parkinson's disease (PD), the emergence of symptoms refractory to conventional therapy poses therapeutic challenges. The success of deep brain stimulation (DBS) and advances in the understanding of the pathophysiology of PD have raised interest in noninvasive brain stimulation as an alternative therapeutic tool. The rationale for its use draws from the concept that reversing abnormalities in brain activity and physiology thought to cause the clinical deficits may restore normal functioning. Currently the best evidence in support of this concept comes from DBS, which improves motor deficits, and modulates brain activity and motor cortex physiology, although whether a causal interaction exists remains largely undetermined. Most trials of noninvasive brain stimulation in PD have applied repetitive transcranial magnetic stimulation (rTMS), targeting the motor cortex. Current studies suggest a possible therapeutic potential for rTMS and transcranial direct current stimulation (tDCS), but clinical effects so far have been small and negligible with regard to functional independence and quality of life. Approaches to potentiate the efficacy of rTMS include increasing stimulation intensity and novel stimulation parameters that derive their rationale from studies on brain physiology. These novel parameters are intended to simulate normal firing patterns or to act on the hypothesized role of oscillatory activity in the motor cortex and basal ganglia with regard to motor control and its contribution to the pathogenesis of motor disorders. Noninvasive brain stimulation studies will enhance our understanding of PD pathophysiology and might provide further evidence for potential therapeutic applications.

This patient was sporadically treated with corticoids. When made the medical consult had lost 34lb., was under anorexy, as well as dyspepsia. Hemoglobyn 6.9 gr/dl, leucocytes 20000/mm3, neutrofils at 90%, proteinogram the same as former, with hypoalbuminemia. She was taking prednisona, 16 mg/day. When examined showed depress of conscience, astenia, and dermic lesions already quoted. 4 cm nonpainful right axillary adenopaty adhered to deep planes. Medulogram with increased iron, hyperegenerative. Ganglionar biopsia: linfoid hyperplasic process linked to inmune response. Toracoabdominal tomography with adenomegalia in torax and retroperitoneo. Skin biopsia: neutrofilic vasculitis. The patient suspends the 16 mg of prednisona and fever as well as generalized adenopatias come up. After laying aside other ethiologies, and understanding as Castleman Multicentric disease, it is started to supply prednisona 1 mg/kg of weight with a clinical and biochemical fast and outstanding response. After 7 months it was progressively suspended the esteroids and 60 days later, the process fall back; for that, corticoids are restarted, with a good evolution. The illness of Castleman although it is not very frequent, it should be considered as differential diagnosis in those clinical cases that are accompanied with important general commitment, linphadenopaties and respons to steroid therapy.

    On the basis of strong research evidence, Duchenne muscular dystrophy (DMD), the most common severe childhood form of muscular dystrophy, is an X-linked recessive disorder caused by out-of-frame mutations of the dystrophin gene. Thus, it is classified asa dystrophinopathy. The disease onset is before age 5 years. Patients with DMD present with progressive symmetrical limb-girdle muscle weakness and become wheelchair dependent after age 12 years. (2)(3). On the basis of some research evidence,cardiomyopathy and congestive heart failure are usually seen in the late teens in patients with DMD. Progressive scoliosis and respiratory in sufficiency often develop once wheelchair dependency occurs. Respiratory failure and cardiomyopathy are common causes of death, and few survive beyond the third decade of life. (2)(3)(4)(5)(6)(7). On the basis of some research evidence, prednisone at 0.75 mg/kg daily (maximum dose, 40 mg/d) or deflazacort at 0.9 mg/kg daily (maximum dose, 39 mg/d), a derivative of prednisolone (not available in the United States), as a single morning dose is recommended for DMD patients older than 5 years, which may prolong independent walking from a few months to 2 years. (2)(3)(16)(17). Based on some research evidence, treatment with angiotensin-converting enzyme inhibitors, b-blockers, and diuretics has been reported to be beneficial in DMD patients with cardiac abnormalities. (2)(3)(5)(18). Based on expert opinion, children with muscle weakness and increased serum creatine kinase levels may be associated with either genetic or acquired muscle disorders (Tables 1 and 3).

    Full Text Available Alzheimer Disease (AD is an outcome as well as source of many diseases. Alzheimer is linked with many other diseases like Diabetes type 2, cholesterolemia, hypertension and many more. But how each of these diseases affecting other is still unknown to scientific community. Signaling Pathways of one disease is interlinked with other disease. But to what extent healthy brain is affected when any signaling in human body is disturbed is the question that matters. There is a need of Pathway analysis, Protein-Protein interaction (PPI and the conserved interactome study in AD and linked diseases. It will be helpful in finding the potent drug or vaccine target in conscious manner. In the present research the Protein-Protein interaction of all the proteins involved in Alzheimer Disease is analyzed using ViSANT and osprey tools and pathway analysis further reveals the significant genes/proteins linking AD with other diseases.

    2016-01-01

    Airway diseases are the most commonly described lung manifestations of inflammatory bowel disease (IBD). However, the similarities in disease pathogenesis and the sharing of important environmental risk factors and genetic susceptibility suggest that there is a complex interplay between IBD and airway diseases. Recent evidence of IBD occurrence among patients with airway diseases and the higher than estimated prevalence of subclinical airway injuries among IBD patients support the hypothesis of a two-way association. Future research efforts should be directed toward further exploration of this association, as airway diseases are highly prevalent conditions with a substantial public health impact. PMID:27678355

    Understanding how dietary components alter the healthy baseline colonic microenvironment is important in determining their roles in influencing gut health and gut-associated diseases. Dietary flaxseed (FS) has demonstrated anti-colon cancer effects in numerous rodent models, however, exacerbated acute colonic mucosal injury and inflammation in a colitis model. This study investigates whether FS alters critical aspects of gut health in healthy unchallenged mice, which may help explain some of the divergent effects observed following different gut-associated disease challenges. Four-week-old C57Bl/6 male mice were fed an AIN-93G basal diet (BD) or an isocaloric BD+10% ground FS diet for 3 weeks. FS enhanced colon goblet cell density, mucus production, MUC2 mRNA expression, and cecal short chain fatty acid levels, indicative of beneficial intestinal barrier integrity responses. Additionally, FS enhanced colonic regenerating islet-derived protein 3 gamma (RegIIIγ) and reduced MUC1 and resistin-like molecule beta (RELMβ) mRNA expression which may indicate altered responses in regulating microbial defense and injury repair responses. FS diet altered the fecal microbial community structure (16S rRNA gene profiling), including a 20-fold increase in Prevotella spp. and a 30-fold reduction in Akkermansia muciniphila abundance. A 10-fold reduction in A. muciniphila abundance by FS was also demonstrated in the colon tissue-associated microbiota (quantitative PCR). Furthermore, fecal branched chain fatty acids were increased by FS, indicative of increased microbial-derived putrefactive compounds. In conclusion, consumption of a FS-supplemented diet alters the baseline colonic microenvironment of healthy mice which may modify subsequent mucosal microbial defense and injury-repair responses leading to altered susceptibility to different gut-associated diseases.

    Science.gov (United States)

    Sood, Vikrant; Rawat, Dinesh; Khanna, Rajeev; Alam, Seema

    2015-03-01

    Wilson disease and cholestatic liver diseases may present as a diagnostic dilemma if standard guidelines incorporating markers of copper overload are followed. We hereby present a series of four cases of sclerosing cholangitis masquerading as Wilson disease. True Wilson disease cases had significantly lower ceruloplasmin (6 vs. 16 mg/dL) and higher 24-hour urinary copper (322.3 vs. 74.5 μg/day) as compared to mimickers. Initial low serum ceruloplasmin levels normalized in mimickers on follow up, and this may used as a diagnostic indicator. Standard Wilson disease diagnostic criteria thus need further modification especially in developing countries to help avoid mismanagement.

  5. Liver in systemic disease

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Potential causes of abnormal liver function tests include viral hepatitis, alcohol intake, nonalcoholic fatty liver disease, autoimmune liver diseases, hereditary diseases, hepatobiliary malignancies or infection, gallstones and drug-induced liver injury. Moreover, the liver may be involved in systemic diseases that mainly affect other organs. Therefore, in patients without etiology of liver injury by screening serology and diagnostic imaging, but who have systemic diseases, the abnormal liver function test results might be caused by the systemic disease. In most of these patients, the systemic disease should be treated primarily. However, some patients with systemic disease and severe liver injury or fulminant hepatic failure require intensive treatments of the liver.

  6. Disease cycle approach to plant disease prediction.

    Science.gov (United States)

    De Wolf, Erick D; Isard, Scott A

    2007-01-01

    Plant disease cycles represent pathogen biology as a series of interconnected stages of development including dormancy, reproduction, dispersal, and pathogenesis. The progression through these stages is determined by a continuous sequence of interactions among host, pathogen, and environment. The stages of the disease cycle form the basis of many plant disease prediction models. The relationship of temperature and moisture to disease development and pathogen reproduction serve as the basis for most contemporary plant disease prediction systems. Pathogen dormancy and inoculum dispersal are considered less frequently. We found extensive research efforts evaluating the performance of prediction models as part of operation disease management systems. These efforts appear to be greater than just a few decades ago, and include novel applications of Bayesian decision theory. Advances in information technology have stimulated innovations in model application. This trend must accelerate to provide the disease management strategies needed to maintain global food supplies.

    Wilson's disease is a hereditary autosomal recessive disorder of copper metabolism,characterized by copper accumulation in the liver and brain. This rare entity, which has a broad clinical spectrum, is often difficult to diagnose and should therefore always be suspected in patients with liver disease of unclear cause. We describe two types of manifestation of liver disease in two patients; the first developed fulminant hepatic failure requiring urgent liver transplantation and the second showed advanced chronic liver disease and received standard medical treatment. The objective of this clinical observation is to analyze the diagnosis of Wilson's disease in two patients with distinct onset, illustrating the broad clinical spectrum of the disease, and its treatment.

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

    Genetic diseases that do not primarily affect the genitourinary tract may have urologic manifestations. These urologic manifestations range from benign and malignant renal disease to infertility. Thus, the practicing urologist may be involved in the care of these patients and should have knowledge of these diseases. Continued improvements in the diagnosis and treatment of these genetic diseases will likely result in improved survival and will increase the number of patients who may develop urologic manifestations of these diseases.

    2005-05-01

    The cornea is naturally transparent. Anything that interferes with the cornea's stromal architecture, contributes to blood vessel migration, increases corneal pigmentation, or predisposes to corneal edema, disrupts the corneas transparency and indicates corneal disease. The color, location, and shape and pattern of a corneal lesion can help in determining the underlying cause for the disease. Corneal disease is typically divided into congenital or acquired disorders. Congenital disorders, such as corneal dermoids are rare in cats, whereas acquired corneal disease associated with nonulcerative or ulcerative keratitis is common. Primary ocular disease, such as tear film instability, adenexal disease (medial canthal entropion, lagophthalmus, eyelid agenesis), and herpes keratitis are associated with the majority of acquired corneal disease in cats. Proliferative/eosinophilic keratitis, acute bullous keratopathy, and Florida keratopathy are common feline nonulcerative disorders. Nonprogressive ulcerative disease in cats, such as chronic corneal epithelial defects and corneal sequestration are more common than progressive corneal ulcerations.

    In many neurological diseases a depressive syndrome is a characteristic sign of the primary disease or is an important comorbidity. Post-stroke depression, for example, is a common and relevant complication following ischemic brain infarction. Approximately 4 out of every 10 stroke patients develop depressive disorders in the course of the disease which have a disadvantageous effect on the course and the prognosis. On the other hand depression is also a risk factor for certain neurological diseases as was recently demonstrated in a meta-analysis of prospective cohort studies which revealed a much higher stroke risk for depressive patients. Furthermore, depression plays an important role in other neurological diseases with respect to the course and quality of life, such as Parkinson's disease, multiple sclerosis and epilepsy. This article gives a review of the most important epidemiological, pathophysiological and therapeutic aspects of depressive disorders as a comorbidity of neurological diseases and as a risk factor for neurological diseases.

    2006-01-01

    Inflammatory bowel disease is an important cause of gastrointestinal pathology in children and adolescents.The incidence of pediatric inflammatory bowel disease is increasing; therefore, it is important for the clinician to be aware of the presentation of this disease in the pediatric population. Laboratory tests, radiology studies,and endoscopic procedures are helpful in diagnosing inflammatory bowel disease and differentiating between Crohn's disease and ulcerative colitis. Once diagnosed,the goal of medical management is to induce remission of disease while minimizing the side effects of the medication. Specific attention needs to be paid to achieving normal growth in this susceptible population.Surgical management is usually indicated for failure of medical management, complication, or malignancy.Algorithms for diagnostic evaluation and treatment of pediatric inflammatory bowel disease are presented.The specific psychosocial issues facing these patients are also discussed in this review as are the future goals of research in the complex problem of pediatric inflammatory bowel disease.

This study discusses the hallmarks of emerging diseases, describing the existence of noninfectious emerging diseases, and elaborating on the advantages of defining noninfectious diseases as emerging ones. From the discussion of various mental health disorders, nutritional deficiencies, external injuries and violence outcomes, work injuries and occupational health, and diseases due to environmental factors, the conclusion is drawn that a wide variety of noninfectious diseases can be defined as emergent. Noninfectious emerging diseases need to be identified in order to improve their control and management. A new definition of "emergent disease" is proposed, one that emphasizes the pathways of emergence and conceptual traits, rather than descriptive features.

    Approaches to the study of the genetic basis of common complex diseases and their clinical applications are considered. Monogenic Mendelian inheritance in such conditions is infrequent but its elucidation may help to detect pathogenic mechanisms in the more common variety of complex diseases. Involvement by multiple genes in complex diseases usually occurs but the isolation and identification of specific genes so far has been exceptional. The role of common polymorphisms as indicators of disease risk in various studies is discussed.

It has also been called acid maltase deficiency and glycogen storage disease type II. There is a broad clinical presentation: the most severe form that presents in the first few months of life with cardiomyopathy and generalized muscle weakness that rapidly progresses to death from cardio-respiratory failure in the first year of life (infant-onset Pompe disease. A more slowly progressive disease, with little or no cardiac involvement, presents with proximal myopathy and/or pulmonary insufficiency, from the second year of life to late adulthood (late-onset Pompe disease. The recent development and introduction of enzyme replacement therapy with intravenous infusion of recombinant human acid alpha-glucosidase have made a major improvement in the morbidity and mortality of this disease. New therapies are also in development. With the availability of treatment, diagnostic methods have also improved, allowing for earlier recognition and potential early therapeutic intervention. The advent of newborn screening for Pompe disease may identify patients who can be treated before significant irreversible disease has occurred.

    2016-06-01

    Glycation is a spontaneous age-dependent posttranslational modification that can impact the structure and function of several proteins. Interestingly, glycation can be detected at the periphery of Lewy bodies in the brain in Parkinson's disease. Moreover, α-synuclein can be glycated, at least under experimental conditions. In Alzheimer's disease, glycation of amyloid β peptide exacerbates its toxicity and contributes to neurodegeneration. Recent studies establish diabetes mellitus as a risk factor for several neurodegenerative disorders, including Parkinson's and Alzheimer's diseases. However, the mechanisms underlying this connection remain unclear. We hypothesize that hyperglycemia might play an important role in the development of these disorders, possibly by also inducing protein glycation and thereby dysfunction, aggregation, and deposition. Here, we explore protein glycation as a common player in Parkinson's and Alzheimer's diseases and propose it may constitute a novel target for the development of strategies for neuroprotective therapeutic interventions. © 2016 International Parkinson and Movement Disorder Society.

    Different rates of progression have been observed among patients with Alzheimer disease. Risk factors that accelerate deterioration have been identified and some are being discussed, such as genetics, comorbidity, and the early appearance of Alzheimer disease motor signs. Progressive forms of Alzheimer disease have been reported with rapid cognitive decline and disease duration of only a few years. This short review aims to provide an overview of the current knowledge of rapidly progressive Alzheimer disease. Furthermore, we suggest that rapid, in this context, should be defined as a Mini-Mental State Examination score decrease of 6 points per year.

    Neurodegenerative diseases pose a significant problem for the healthcare system, doctors, and patients. With an aging population, more and more individuals are developing neurodegenerative diseases and there are few treatment options at the present time. Meditation techniques present an interesting potential adjuvant treatment for patients with neurodegenerative diseases and have the advantage of being inexpensive, and easy to teach and perform. There is increasing research evidence to support the application of meditation techniques to help improve cognition and memory in patients with neurodegenerative diseases. This review discusses the current data on meditation, memory, and attention, and the potential applications of meditation techniques in patients with neurodegenerative diseases.

    Vaserman, Nathalie

    2005-12-01

    Parkinson's disease is associated with an increased risk of falls. The risk is greatest in patients with advanced disease. Because Parkinson's disease usually occurs late in life, the risk factors related to the neurological impairments add to those associated with aging. The incidence of fractures is high in patients with Parkinson's disease, with femoral neck fractures in older women being particularly common. Risk factors for fractures include a low body mass index, limited exposure to sunlight, an inadequate vitamin D intake with low 25-OH vitamin D levels, and bone loss. Several studies found decreased bone mineral density values at the femoral neck and lumbar spine in patients with Parkinson's disease. Although this decrease is ascribable in part to factors unrelated with Parkinson's disease, such as older age and female gender, Parkinson's disease itself also plays a role, most notably in patients with severe neurological impairments (Hoehn and Yahr stages III and IV).

    Parkinson's disease is a neurodegenerative disorder clinically characterized by motor impairments (tremor, bradykinesia, rigidity and postural instability) associated or not with non-motor complications (cognitive disorders, dysautonomia). Most of patients loose weight during evolution of their disease. Dysregulations of hypothalamus, which is considered as the regulatory center of satiety and energy metabolism, could play a major role in this phenomenon. Deep brain stimulation of the subthalamic nucleus (NST) is an effective method to treat patients with advanced Parkinson's disease providing marked improvement of motor impairments. This chirurgical procedure also induces a rapid and strong body weight gain and sometimes obesity. This post-operative weight gain, which exceeds largely weight lost recorded in non-operated patient, could be responsible of metabolic disorders (such as diabetes) and cardiovascular diseases. This review describes body weight variations generated by Parkinson' disease and deep brain stimulation of the NST, and focuses on metabolic disorders capable to explain them. Finally, this review emphasizes on the importance of an adequate nutritional follow up care for parkinsonian patient.

  4. Genetics of Proteasome Diseases

    Directory of Open Access Journals (Sweden)

    Aldrin V. Gomes

    2013-01-01

    Full Text Available The proteasome is a large, multiple subunit complex that is capable of degrading most intracellular proteins. Polymorphisms in proteasome subunits are associated with cardiovascular diseases, diabetes, neurological diseases, and cancer. One polymorphism in the proteasome gene PSMA6 (−8C/G is associated with three different diseases: type 2 diabetes, myocardial infarction, and coronary artery disease. One type of proteasome, the immunoproteasome, which contains inducible catalytic subunits, is adapted to generate peptides for antigen presentation. It has recently been shown that mutations and polymorphisms in the immunoproteasome catalytic subunit PSMB8 are associated with several inflammatory and autoinflammatory diseases including Nakajo-Nishimura syndrome, CANDLE syndrome, and intestinal M. tuberculosis infection. This comprehensive review describes the disease-related polymorphisms in proteasome genes associated with human diseases and the physiological modulation of proteasome function by these polymorphisms. Given the large number of subunits and the central importance of the proteasome in human physiology as well as the fast pace of detection of proteasome polymorphisms associated with human diseases, it is likely that other polymorphisms in proteasome genes associated with diseases will be detected in the near future. While disease-associated polymorphisms are now readily discovered, the challenge will be to use this genetic information for clinical benefit.

    2012-02-03

    Whether there is an association between coeliac disease and epilepsy is uncertain. Recently, a syndrome of coeliac disease, occipital lobe epilepsy and cerebral calcification has been described, mostly in Italy. We measured the prevalence of coeliac disease in patients attending a seizure clinic, and investigated whether cerebral calcification occurred in patients with both coeliac disease and epilepsy. Screening for coeliac disease was by IgA endomysial antibody, measured by indirect immunofluorescence using sections of human umbilical cord. Of 177 patients screened, four patients were positive. All had small-bowel histology typical of coeliac disease. The overall frequency of coeliac disease in this mixed patient sample was 1 in 44. In a control group of 488 pregnant patients, two serum samples were positive (1 in 244). Sixteen patients with both coeliac disease and epilepsy, who had previously attended this hospital, were identified. No patient had cerebral calcification on CT scanning. Coeliac disease appears to occur with increased frequency in patients with epilepsy, and a high index of suspicion should be maintained. Cerebral calcification is not a feature of our patients with epilepsy and coeliac disease, and may be an ethnically-or geographically-restricted finding.

    2015-12-01

    Full Text Available Multiple cystic lung disease represents a diverse group of uncommon disorders that can present a diagnostic challenge due to the increasing number of diseases associated with this presentation. High-resolution computed tomography of the chest helps to define the morphological aspects and distribution of lung cysts, as well as associated findings. The combination of appearance upon imaging and clinical features, together with extrapulmonary manifestations, when present, permits confident and accurate diagnosis of the majority of these diseases without recourse to open-lung biopsy. The main diseases in this group that are discussed in this review are lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis and folliculin gene-associated syndrome (Birt–Hogg–Dubé; other rare causes of cystic lung disease, including cystic metastasis of sarcoma, are also discussed. Disease progression is unpredictable, and understanding of the complications of cystic lung disease and their appearance during evolution of the disease are essential for management. Correlation of disease evolution and clinical context with chest imaging findings provides important clues for defining the underlying nature of cystic lung disease, and guides diagnostic evaluation and management.

  7. Celiac disease and gluten-associated diseases.

    Science.gov (United States)

    Helms, Steve

    2005-09-01

    Celiac disease develops from an autoimmune response to specific dietary grains that contain gluten. Diagnosis can be made based on the classical presentation of diarrhea, fatty stools, and abdominal bloating and cramping, as well as the presence of specific serum antibodies. In addition, gluten ingestion has increasingly been found to be associated with other conditions not usually correlated with gluten intolerance. The subsequent diversity of the clinical presentation in these cases can complicate decision-making and delay treatment initiation in conditions such as ataxia, headaches, arthritis, neuropathy, type 1 diabetes mellitus, and others. This review explores the etiology and pathology of celiac disease, presents support for the relationship between gluten and other diseases, and provides effective screening and treatment protocols.

    Rapid excessive alcohol drinking frequently causes disturbance of consciousness due to head trauma, brain edema, hypoglycemia, hyponatremia, hepatic coma and so on, provoked by acute alcohol intoxication. Rapid differential diagnosis and management are extremely important to save a life. On the other hands, the chronic users of alcohol so called alcoholism has many kinds of physical diseases such as liver diseases (i.e., fatty liver, alcoholic hepatitis, alcoholic liver cirrhosis and miscellaneous liver disease), diabetes mellitus, injury to happen in drunkenness, pancreas disease (i.e., acute and chronic pancreatitis and deterioration of chronic pancreatitis), gastrontestinal diseases (i.e., gastroduodenal ulcer), and so on. Enough attention should be paid to above mentioned diseases, otherwise they would turn worse more with continuation and increase in quantity of the alcohol. It should be born in its mind that the excessive drinking becomes the weapon threatening life.

    This article presents the actual classification of neuromuscular diseases based on present expansion of our knowledge and understanding due to genetic developments. It summarizes the genetic and clinical presentations of each disorder together with CT findings, which we studied in a large group of patients with neuromuscular diseases. The muscular dystrophies as the largest and most common group of hereditary muscle diseases will be highlighted by giving detailed information about the role of CT and MRI in the differential diagnosis. The radiological features of neuromuscular diseases are atrophy, hypertrophy, pseudohypertrophy and fatty infiltration of muscles on a selective basis. Although the patterns and distribution of involvement are characteristic in some of the diseases, the definition of the type of disease based on CT scan only is not always possible.

    Sanz, Joaquín; Meloni, Sandro; Moreno, Yamir

    2014-01-01

    Current modeling of infectious diseases allows for the study of complex and realistic scenarios that go from the population to the individual level of description. Most epidemic models however assume that the spreading process takes place on a single level (be it a single population, a meta-population system or a network of contacts). The latter is in part a consequence of our still limited knowledge about the interdependency of the many mechanisms and factors involved in disease spreading. In particular, interdependent contagion phenomena can only be addressed if we go beyond the scheme one pathogen-one network. In this paper, we study a model that allows describing the spreading dynamics of two concurrent diseases and apply it to a paradigmatic case of disease-disease interaction: the interaction between AIDS and Tuberculosis. Specifically, we characterize analytically the epidemic thresholds of the two diseases for different scenarios and also compute the temporal evolution characterizing the unfolding dyn...

    Ageing, which all creatures must encounter, is a challenge to every living organism. In the human body, it is estimated that cell division and metabolism occurs exuberantly until about 25 years of age. Beyond this age, subsidiary products of metabolism and cell damage accumulate, and the phenotypes of ageing appear, causing disease formation. Among these age-related diseases, neurodegenerative diseases have drawn a lot of attention due to their irreversibility, lack of effective treatment, and accompanied social and economical burdens. In seeking to ameliorate ageing and age-related diseases, the search for anti-ageing drugs has been of much interest. Numerous studies have shown that the plant polyphenol, resveratrol (3,5,4'-trihydroxystilbene), extends the lifespan of several species, prevents age-related diseases, and possesses anti-inflammatory, and anti-cancer properties. The beneficial effects of resveratrol are believed to be associated with the activation of a longevity gene, SirT1. In this review, we discuss the pathogenesis of age-related neurodegenerative diseases including Alzheimer's disease, Parkinson's disease and cerebrovascular disease. The therapeutic potential of resveratrol, diet and the roles of stem cell therapy are discussed to provide a better understanding of the ageing mystery.

    Gaucher disease is a lysosomal storage disorder due to deficiency of glucocerebrosidase. The association with pregnancy exposes the worsening of the disease and complications of pregnancy and puerperium. We report a case of pregnancy in a woman of 35 years, suffering from Gaucher disease type 1. Pregnancy had a favorable outcome. Complications occurred. They were kept under control. The outcome was favorable. The authors discuss the evolution of the disease during pregnancy and management of complications. They can occur during pregnancy, post-partum and breastfeeding. Support begins with preconception consultation. It involves finding and correcting the biological problems and deficiencies, and management of complications. Genetic counseling is important, it helps prevent inbreeding.

    2014-08-01

    Zoonotic diseases are infectious diseases that are naturally transmitted from vertebrate animals to humans and vice versa. They are caused by all types of pathogenic agents, including bacteria, parasites, fungi, viruses and prions. Although they have been recognised for many centuries, their impact on public health has increased in the last few decades due to a combination of the success in reducing the spread of human infectious diseases through vaccination and effective therapies and the emergence of novel zoonotic diseases. It is being increasingly recognised that a One Health approach at the human-animal-ecosystem interface is needed for effective investigation, prevention and control of any emerging zoonotic disease. Here, the authors will review the drivers for emergence, highlight some of the high-impact emerging zoonotic diseases of the last two decades and provide examples of novel One Health approaches for disease investigation, prevention and control. Although this review focuses on emerging zoonotic viral diseases, the authors consider that the discussions presented in this paper will be equally applicable to emerging zoonotic diseases of other pathogen types.

    Objective To review the role of epigenetic regulation in neonatal diseases and better understand Barker's "fetal origins of adult disease hypothesis".Data sources The data cited in this review were mainly obtained from the articles published in Medline/PubMed between January 1953 and December 2009.Study selection Articles associated with epigenetics and neonatal diseases were selected.Results There is a wealth of epidemiological evidence that lower birth weight is strongly correlated with an increased risk of adult diseases, such as type 2 diabetes mellitus, hypertension, and cardiovascular disease. This phenomenon of fetal origins of adult disease is strongly associated with fetal insults to epigenetic modifications of genes. A potential role of epigenetic modifications in congenital disorders, transient neonatal diabetes mellitus (TNDM), intrauterine growth retardation (IUGR), and persistent pulmonary hypertension of the newborn (PPHN) have been studied.Conclusions Acknowledgment of the role of these epigenetic modifications in neonatal diseases would be conducive to better understanding the pathogenesis of these diseases, and provide new insight for improved treatment and prevention of later adult diseases.

    Pfützer, Roland H; Kruis, Wolfgang

    2015-11-01

    Diverticular disease is a common condition in Western countries and the incidence and prevalence of the disease is increasing. The pathogenetic factors involved include structural changes in the gut that increase with age, a diet low in fibre and rich in meat, changes in intestinal motility, the concept of enteric neuropathy and an underlying genetic background. Current treatment strategies are hampered by insufficient options to stratify patients according to individual risk. One of the main reasons is the lack of an all-encompassing classification system of diverticular disease. In response, the German Society for Gastroenterology and Digestive Diseases (DGVS) has proposed a classification system as part of its new guideline for the diagnosis and management of diverticular disease. The classification system includes five main types of disease: asymptomatic diverticulosis, acute uncomplicated and complicated diverticulitis, as well as chronic diverticular disease and diverticular bleeding. Here, we review prevention and treatment strategies stratified by these five main types of disease, from prevention of the first attack of diverticulitis to the management of chronic complications and diverticular bleeding.

  2. Liver disease in pregnancy

    2009-01-01

    Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy.

    There has been a significant increase in research activity into infectious diseases in Spain in the last few years. The Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) currently has ten study groups, with the cooperation of infectious diseases specialists and microbiologists from different centres, with significant research activity. The program of Redes Temáticas de Investigación Cooperativa en Salud (Special Topics Cooperative Health Research Networks) is an appropriate framework for the strategic coordination of research groups from the Spanish autonomous communities. The Spanish Network for Research in Infectious Diseases (REIPI) and the Network for Research in AIDS (RIS) integrate investigators in Infectious Diseases from multiple groups, which continuously perform important research projects. Research using different experimental models in infectious diseases, in numerous institutions, is an important activity in our country. The analysis of the recent scientific production in Infectious Diseases shows that Spain has a good position in the context of the European Union. The research activity in Infectious Diseases carried out in our country is a great opportunity for the training of specialists in this area of knowledge.

    Full Text Available Paget’s disease of bone is the most common metabolic bone disease after osteoporosis and affects 2-4% of adults over 55 years of age. Its etiology is only partly understood and includes both genetic and environmental factors. The disease may be asymptomatic and can be uncovered incidentally on x-ray or in biochemical tests performed for another condition. It can also manifest itself with bone pain, deformity, fracture or other complications. Paget’s disease is diagnosed by x-rays and in general has very typical radiological features, but occasionally the clinical picture may be unusual and a differential diagnosis of sclerotic or lytic metastases needs to be considered. Plasma total alkaline phosphatase activity is the most clinically useful indicator of disease activity. It is elevated in most untreated patients, but may be within the normal range in patients with monostotic or limited disease. Bisphosphonate therapy is indicated for patients with symptoms and should also be considered in patients with disease sites that suggest a risk of complications, such as long bones, vertebrae or base of the skull. Orthopedic surgery in Paget’s disease patients includes almost exclusively the correction of fractures and arthroplasty.

  7. AUTOINFLAMMATORY PUSTULAR NEUTROPHILIC DISEASES

    Science.gov (United States)

    Naik, Haley B.; Cowen, Edward W.

    2013-01-01

    SYNOPSIS The inflammatory pustular dermatoses constitute a spectrum of non-infectious conditions ranging from localized involvement to generalized disease with associated acute systemic inflammation and multi-organ involvement. Despite the variability in extent and severity of cutaneous presentation, each of these diseases is characterized by non-infectious neutrophilic intra-epidermal microabscesses. Many share systemic findings including fever, elevated inflammatory markers, inflammatory bowel disease and/or osteoarticular involvement, suggesting potential common pathogenic links (Figure 1). The recent discoveries of several genes responsible for heritable pustular diseases have revealed a distinct link between pustular skin disease and regulation of innate immunity. These genetic advances have led to a deeper exploration of common pathways in pustular skin disease and offer the potential for a new era of biologic therapy which targets these shared pathways. This chapter provides a new categorization of inflammatory pustular dermatoses in the context of recent genetic and biologic insights. We will discuss recently-described monogenic diseases with pustular phenotypes, including deficiency of IL-1 receptor antagonist (DIRA), deficiency of the IL-36 receptor antagonist (DITRA), CARD14-associated pustular psoriasis (CAMPS), and pyogenic arthritis, pyoderma gangrenosum, acne (PAPA). We will then discuss how these new genetic advancements may inform how we view previously described pustular diseases, including pustular psoriasis and its clinical variants, with a focus on historical classification by clinical phenotype.

  8. Psoriasis, a Systemic Disease?

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Psoriasis is a chronic inflammatory disease which is characterized by plaques with shiny white desquamation on the skin. It affects 1 to 3% of different ethnic populations. The disease significantly lowers the quality of life for the patients as the lesions appear on visible regions such as the scalp, face and extremities causing pruritus and extensive use of topical agents with a poor rate of recovery and the disease has a recurrent course with frequent attacks. Psoriasis was previously assumed to be a cutaneous disease resulting from epidermal cell hyperproliferation for a long time. However, studies conducted on the etiopathogenesis of the disease revealed that psoriasis is a chronic autoinflammatory disease which is caused by immune system dysregulation. Recently, the frequent association of psoriasis with other autoinflammatory diseases, comorbidities and complications which indeed shorten life expectancy concluded that psoriasis is a systemic disease and created a major difference in its treatment and follow-up modalities. In this review, the comorbidities, which are shown to be related to systemic inflammation and which also share a common pathogenesis with psoriasis, will be discussed.

The case is of interest to doctors of different specialties for the differential diagnosis of anemia and malabsorption syndrome, demonstrate both the classic version, and atypical forms of the disease course. Diagnosis of celiac disease is based on three key positions: clinical findings, histology and serological markers. The clinical picture of celiac disease is characterized by pronounced polymorphism, by going beyond the a gastroenterological pathology. For screening of gluten sensitive celiac typically used an antibody to tissue transglutaminase. Morphological research of the mucous membrane of the small intestine is the determining criterion in the diagnosis of celiac disease. The use of specific gluten-free diet leads to the positive dynamics of the disease and improve the quality of life of patients.

  2. Autophagy in Inflammatory Diseases

    Directory of Open Access Journals (Sweden)

    Alexander J. S. Choi

    2011-01-01

    Full Text Available Autophagy provides a mechanism for the turnover of cellular organelles and proteins through a lysosome-dependent degradation pathway. During starvation, autophagy exerts a homeostatic function that promotes cell survival by recycling metabolic precursors. Additionally, autophagy can interact with other vital processes such as programmed cell death, inflammation, and adaptive immune mechanisms, and thereby potentially influence disease pathogenesis. Macrophages deficient in autophagic proteins display enhanced caspase-1-dependent proinflammatory cytokine production and the activation of the inflammasome. Autophagy provides a functional role in infectious diseases and sepsis by promoting intracellular bacterial clearance. Mutations in autophagy-related genes, leading to loss of autophagic function, have been implicated in the pathogenesis of Crohn's disease. Furthermore, autophagy-dependent mechanisms have been proposed in the pathogenesis of several pulmonary diseases that involve inflammation, including cystic fibrosis and pulmonary hypertension. Strategies aimed at modulating autophagy may lead to therapeutic interventions for diseases associated with inflammation.

    Science.gov (United States)

    John, Seby; Hajj-Ali, Rula A

    2014-03-01

    Autoimmune diseases are a group of heterogeneous inflammatory disorders characterized by systemic or localized inflammation, leading to ischemia and tissue destruction. These include disorders like systemic lupus erythematosus and related diseases, systemic vasculitides, and central nervous system (CNS) vasculitis (primary or secondary). Headache is a very common manifestation of CNS involvement of these diseases. Although headache characteristics can be unspecific and often non-diagnostic, it is important to recognize because headache can be the first manifestation of CNS involvement. Prompt recognition and treatment is necessary not only to treat the headache, but also to help prevent serious neurological sequelae that frequently accompany autoimmune diseases. In this review, we discuss headache associated with autoimmune diseases along with important mimics.

  4. Biomarkers in Airway Diseases

    Directory of Open Access Journals (Sweden)

    Janice M Leung

    2013-01-01

    Full Text Available The inherent limitations of spirometry and clinical history have prompted clinicians and scientists to search for surrogate markers of airway diseases. Although few biomarkers have been widely accepted into the clinical armamentarium, the authors explore three sources of biomarkers that have shown promise as indicators of disease severity and treatment response. In asthma, exhaled nitric oxide measurements can predict steroid responsiveness and sputum eosinophil counts have been used to titrate anti-inflammatory therapies. In chronic obstructive pulmonary disease, inflammatory plasma biomarkers, such as fibrinogen, club cell secretory protein-16 and surfactant protein D, can denote greater severity and predict the risk of exacerbations. While the multitude of disease phenotypes in respiratory medicine make biomarker development especially challenging, these three may soon play key roles in the diagnosis and management of airway diseases.

    Yuen, Noah K; Ananthakrishnan, Shubha; Campbell, Michael J

    2016-01-01

    Renal hyperparathyroidism (rHPT) is a common complication of chronic kidney disease characterized by elevated parathyroid hormone levels secondary to derangements in the homeostasis of calcium, phosphate, and vitamin D. Patients with rHPT experience increased rates of cardiovascular problems and bone disease. The Kidney Disease: Improving Global Outcomes guidelines recommend that screening and management of rHPT be initiated for all patients with chronic kidney disease stage 3 (estimated glomerular filtration rate, < 60 mL/min/1.73 m2). Since the 1990s, improving medical management with vitamin D analogs, phosphate binders, and calcimimetic drugs has expanded the treatment options for patients with rHPT, but some patients still require a parathyroidectomy to mitigate the sequelae of this challenging disease.

    2007-01-01

    AIM: To investigate some possible etiologies of achalasia by screening patients with achalasia for some autoimmune diseases such as thyroid disease.METHODS: We examined 30 known cases of achalasia (20 females, 10 males). Their age ranged 15-70 years.All of them were referred to our institute for treatment.Their sera were evaluated to detect some possible associations with rheumatoid disease, thyroid disease,inflammatory process, anemia, etc.RESULTS: Seven out of 30 patients (23%) had thyroid disease including four patients with hypothyroidism (13.3%), two patients with hyperthyroidism (6.6%),and one had only thyroid nodule but was in euthyroid state (3.3%). Two of these hypothyroid patients had no related clinical symptoms (subclinical) and two had clinical manifestations of hypothyroidism. There were no correlations between the intensity of thyroid diseases and the severity of achalasia symptoms.CONCLUSION: The etiology of achalasia is unknown although autoimmunity has been implicated and is supported by several studies. Thyroid disease presents concomitantly with achalasia in about one fourth of our patients who may have a common etiology.

  8. Domoic Acid Epileptic Disease

    Directory of Open Access Journals (Sweden)

    John S. Ramsdell

    2014-03-01

    Full Text Available Domoic acid epileptic disease is characterized by spontaneous recurrent seizures weeks to months after domoic acid exposure. The potential for this disease was first recognized in a human case study of temporal lobe epilepsy after the 1987 amnesic shellfish-poisoning event in Quebec, and was characterized as a chronic epileptic syndrome in California sea lions through investigation of a series of domoic acid poisoning cases between 1998 and 2006. The sea lion study provided a breadth of insight into clinical presentations, unusual behaviors, brain pathology, and epidemiology. A rat model that replicates key observations of the chronic epileptic syndrome in sea lions has been applied to identify the progression of the epileptic disease state, its relationship to behavioral manifestations, and to define the neural systems involved in these behavioral disorders. Here, we present the concept of domoic acid epileptic disease as a delayed manifestation of domoic acid poisoning and review the state of knowledge for this disease state in affected humans and sea lions. We discuss causative mechanisms and neural underpinnings of disease maturation revealed by the rat model to present the concept for olfactory origin of an epileptic disease; triggered in dendodendritic synapases of the olfactory bulb and maturing in the olfactory cortex. We conclude with updated information on populations at risk, medical diagnosis, treatment, and prognosis.

    Patients affected by Parkinson's disease are at a high risk for fractures, mainly of the hip. These fractures are caused by falls due to postural imbalance, neurological impairment and reduced bone mass. The purpose of this study was (1) to investigate the correlations and the pathophysiological mechanisms underlying bone loss in Parkinson's disease and appraise bone loss or fracture risk reduction interventions; (2) to develop a research agenda that informs the design and development of risk reduction strategies. Osteoporosis and osteopenia are very common findings in patients with Parkinson's disease, affecting up to 91% of women and 61% of men. Reduced bone mass in Parkinsonian patients seems to be caused mainly by reduced mobility through a mechanism similar to that observed in other neurological diseases. Endocrine (such as vitamin D deficiency), nutritional and iatrogenic factors also play an important role in bone mass depletion. Female gender, disease duration and severity (Hoehn and Yahr stages III and IV), old age and low body mass index are related to more severe osteoporosis. Vitamin D supplementation and bisphosphonates seem to be effective in reducing the risk of nonvertebral fractures in patients affected by Parkinson's disease. Prevention and evaluation of osteoporosis through bone mass density assessment should be considered in all patients with Parkinson's disease.

    Dr. Susan Fisher-Hoch, Virologist and Epidemiologist, will discuss her research and travels associated with viral hemorrhagic fevers. From the Ebola outbreak in Reston, Virginia to outbreaks of Crimean Congo Hemorrhagic Fever in South Africa, Senegal, and Saudi Arabia, Dr. Fisher-Hoch has studied and tracked the pathophysiology of these viral diseases. These studies have led her from the Center for Disease Control in the United States, to Lyon, France where she was instrumental in designing, constructing, and rendering operational a laboratory capable of containing some of the world's most dangerous diseases.

    Full Text Available Creutzfeldt-Jakob disease (CJD is a degenerative central nervous system (CNS disease caused by infection of prion protein (PrP, with clinical features including short course, rapid development and 100% mortality. This article aims to discuss the pathogenesis, histopathological features, clinical manifestations, electroencephalogram (EEG findings, imaging data and treatment progress of this disease based on literature review. Cerebrospinal fluid 14-3-3 protein detection, EEG and MRI are three important methods to make an early diagnosis on patients with suspected CJD, such as elderly patients with rapidly progressive dementia (RPD and young patients with mental symptoms involving multiple systems (MS.

    Full Text Available Gaucher′s disease (GD is the most common amongst the various disorders classified under the lysosomal storage disorders. GD is a model for applications of molecular medicine to clinical delineation, diagnosis, and treatment. The multiorgan and varied presentation of the disease makes it a challenge to diagnose GD early. The advent of enzyme replacement therapy in the early 1990s changed the management, and survival, of patients with GD. In addition to this, development of substrate reduction, pharmacological chaperone, and gene therapies has broadened the horizon for this rare disease. However, in resource-poor countries like ours, optimal management is still a distant dream.

  13. Kirsner's inflammatory bowel disease

    @@ Very few medical textbooks have so thoroughly dominated,and even defined a field, as has Inflammatory Bowel Diseases by Joe Kirsner. Originally co-edited with Roy Shorter of Mayo Clinic, this book, beginning with its first edition in 1975, encapsulated the science and art of caring for patients with Crohn's disease and ulcerative colitis. Thus it is with considerable respect, and indeed some awe and trepidation,that we eagerly embraced the opportunity to assume the editorship of this preeminent textbook and the obligation to transition it to reflect the changing, increasingly complex pathophysiology and treatment of these diseases.

    Full Text Available Periodontitis is the result of complex interrelationships between infectious agents and host factors. Environmental, acquired, and genetic risk factors modify the expression of disease and may, therefore, affect the onset or progression of periodontitis. Numerous studies of the potential mechanisms whereby smoking tobacco may predispose to periodontal disease have been conducted, and it appears that smoking may affect the vasculature, the humoral immune system, and the cellular immune and inflammatory systems, and have effects throughout the cytokine and adhesion molecule network. The aim of present review is to consider the association between smoking and periodontal diseases.

    Full Text Available Hirayama disease, also known as Sobue disease is a rare nonprogressive spinal muscular atrophy. Here, we report a case series of three young males presenting with atrophy of distal upper limb and Hirayama disease as their clinico-radiological diagnosis. Magnetic resonance imaging (MRI revealed loss of cervical lordosis with focal areas of lower cervical cord atrophy in a neutral position. MRI in flexion position revealed, anterior displacement of the detached posterior dura from the underlying lamina compressing the thecal sac and widened posterior epidural space with flow voids seen better on 3D-CISS images. All the three patients were managed conservatively.

    Periodontal disease and chronic gingivitis/stomatitis are the most common feline dental diseases. With routine dental care and increased emphasis on home oral hygiene, these diseases can be controlled. Cats can be seen with a number of other dental disorders, and improved treatment methods such as restorations of early subgingival resorptive lesions, endodontic therapy, and orthodontic therapy can be performed successfully. More study and research are necessary about the gingivitis/stomatitis syndrome and subgingival resorptive lesions so that improved prevention and treatment recommendations can be made.

    Compared to lower limb arterial diseases, upper limb arterial diseases look rare, heterogeneous with various etiologies and a rather vague clinical picture, but with a negligible risk of amputation. Almost all types of arterial diseases can be present in the upper limb, but the anatomical and hemodynamic conditions particular to the upper limb often confuse the issue. Thus, atherosclerosis affects mainly the subclavian artery in its proximal segment where the potential of collateral pathway is high making the symptomatic forms not very frequent whereas the prevalence of subclavian artery stenosis or occlusion is relatively high. The clinical examination and the etiologies are discussed according to the clinical, anatomical and hemodynamic context.

    Full Text Available Crohn disease (CD and ulcerative colitis (UC is an chronic inflammation in the gastrointestinal tract. Colecctively, they are called inflammatory bowel disease (IBD, and about 1,5 millions people in America suffering from UC and CD. The cause of UC and CD is unknown, but the expert believe that UC and CD are caused by a disturbed immune response in someone who has a genetic predisposition. UC and CD have a significant recurrency  and remission rate. Surgery in UC is a curative treatment for colon’s disease and a potentially colon’s malignancy, but it is not a curative treatment for CD.
