Comparative StudyLong-term clinical outcome after botulinum toxin injection in children with nonrelaxing internal anal sphincter.
Children with surgically repaired Hirschsprung's disease (HD) and those with internal anal sphincter (IAS) achalasia may develop obstructive gastrointestinal symptoms and/or enterocolitis due to a functional obstruction caused by an inability of the IAS to relax. Anal sphincter Clostridium botulinum toxin (BoTox) injections may provide a reversible therapy. However, there is limited information regarding the long-term outcomes of children receiving this therapy. The primary aim of this study was to determine the long-term clinical outcomes of BoTox therapy in children with a nonrelaxing IAS. The secondary aim of this study was to determine prognostic factors predicting a favorable outcome following BoTox IAS injection. ⋯ Anal sphincter BoTox may be an effective and safe long-term therapy for children with nonrelaxing IAS.

Review Meta AnalysisOral antibiotic prophylaxis reduces spontaneous bacterial peritonitis occurrence and improves short-term survival in cirrhosis: a meta-analysis.
Spontaneous bacterial peritonitis (SBP) is a serious complication of advanced liver disease resulting in high mortality rates. Although studies that assessed the use of oral antibiotics in advanced liver disease demonstrated a clear benefit in reducing the risk of recurrent peritonitis, it is unclear whether mortality rates are similarly affected by this practice. The goal of this study was to determine whether oral antibiotic therapy provides a survival benefit for patients with advanced cirrhosis and ascites. Through subgroup analysis, we also evaluated the effect of prophylactic oral antibiotic therapy on the prevention of SBP and the incidence of all infections (including SBP) when compared with non-treated or placebo controls. ⋯ Antibiotic prophylaxis improved short-term survival in treated patients when compared with untreated control groups and reduced the overall risk of infections, including SBP, during follow-up. In summary, antibiotic prophylaxis should be considered for high-risk cirrhotic patients with ascites.
