Botox injection to the puborectalis muscle has been found to have a limited therapeutic effect on patients suffering from anismus. Our results justify the need for further double-blind placebo-controlled trials to determine the exact role of botulinum toxin type-A in anismus.
Pediatric onset of CD in our population was associated with a frequent polymorphism in the binding site for NF-kappaB in TNF-alpha promoter but not to defined NOD2/CARD15 disease-associated mutations. This polymorphism is associated with colitis and familial disease. NOD2/CARD15 mutations and the TNF-863C/A polymorphism have equivalent but opposite effects on disease location. These findings may help explain differences in CD phenotype.
In the glycine-treated mice, the serum levels of liver enzymes and TNF-alpha, the histologic necroinflammation score and the mortality rate were significantly reduced compared to control mice (P<0.001). Serum IL-10 levels in the glycine-treated mice were increased (P<0.01). In vitro studies in cultured lymphocytes isolated from either normal or glycine pretreated mice, demonstrated a significant and dose-dependent inhibition of LPS-induced TNF-alpha secretion and increase in IL-10 response after treatment with glycine (P<0.01). In conclusion, glycine reduces hepatic damage and improves survival rate in this mouse model of endotoxemia. The protective effect of glycine is associated with modulation of TNF-alpha and IL-10 secretion.
Background: Confirmation of Helicobacter pylori eradication by urea breath test (UBT) is currently performed 4–6 weeks after completion of therapy because of unacceptable false-negative results in UBTs performed earlier. Use of a high-dose citric acid test meal appears to enable accurate detection of H. pylori even during short term therapy with proton pump inhibitors. Aim: To evaluate if use of a high dose citric acid (4.0 g) test meal can decrease the interval required for confirmation of eradication after triple therapy. Methods: 233 patients positive for H. pylori were randomized to undergo UBT at 7 days or 14 days after triple therapy, and again at 6 weeks. The latter test was considered the gold standard test. Results: The UBT performed 6 weeks after the end of treatment found that 79.9% were cured. The same test 7 days after therapy found false-negative detection of H. pylori in 7.3% patients compared to 3.2% patients examined after 14 days. The sensitivity, specificity, positive and negative predictive values and accuracy for evaluation on day 14 were 80, 100, 100, 96.3 and 96.7%, respectively. Conclusions: High-dose citric acid-based UBT is a valid test for the assessment of H. pylori status 14 days after triple therapy. This may obviate the delay in instituting second-line eradication therapy, or further evaluation of the symptomatic patient unresponsive to therapy despite eradication.
We report a case of recurrent severe upper gastrointestinal bleeding where the bleeding source was difficult to find during recurrent hospitalizations. Eventually videocapsule endoscopy was the modality that finally diagnosed an ulcerated lipoma within an area of intussuscepted jejunum. Segmental resection of small bowel was performed and no further bleeding episodes have occurred. Our case illustrates the value of capsule endoscopy and the rare potential of lipomas to cause serious gastrointestinal bleeding.
The prevalence of H. pylori is considerable even several years after partial gastrectomy. The BreathID is reliable to exclude H. pylori after partial gastrectomy. The positive predictive value of the UBT is not very high but better than the RUT. We suggest that all positive patients found by the breath test should be treated. Our results support the view that alternative noninvasive methods, such as the stool antigen test should be further studied and compared with the BreathID in larger populations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
