Switching From Originator to Biosimilar Infliximab in Paediatric Inflammatory Bowel Disease Is Feasible and Uneventful.

The safety, clinical efficacy, and cost-effectiveness of biosimilar infliximab in adult inflammatory bowel disease (IBD) have now been extensively shown. Limited data have been collected in the paediatric setting. We report nationwide, prospective, clinical safety and effectiveness data for patients from all 3 Scottish paediatric inflammatory bowel disease networks switching from originator to biosimilar infliximab.

Efficacy of oral methotrexate in paediatric Crohn's disease: a multicentre propensity score study.

Background: Oral methotrexate (MTX) administration avoids weekly injections, reduces costs and may improve quality of life of patients with Crohn's disease (CD), especially children. Routes of administration have never been systematically compared in CD. We aimed to compare effectiveness and safety of orally (PO) versus subcutaneously (SC) administered MTX in paediatric CD.

Systematic review: the role of breastfeeding in the development of pediatric inflammatory bowel disease.

Objectives: To assess the current evidence for the role of breastfeeding in the development of early onset inflammatory bowel disease (IBD) with a systematic review.

Study Design: An electronic database search was performed (January 1966-January 2008) with keywords related to IBD and breastfeeding, looking specifically for studies that reported outcome in early-onset disease (<16 years of age) and "any exposure" to breast milk as the variables. Meta-analysis of studies included for review was then performed by using a random effects model, and results were expressed as odds ratios (OR) with 95% CIs.

Mycoplasma pneumoniae associated with hemolytic anemia, cold agglutinins, and recurrent arterial thrombosis.

A 40-year-old white male developed Mycoplasma pneumoniae pneumonia (IgM titer 1:256) as well as autoimmune hemolytic anemia due to cold agglutinins (titer of 1:512). Four days after admission to the hospital, he developed an acute superior mesenteric artery (SMA) thrombosis. Four feet of ischemic small bowel were resected.

Quantification of optison bubble size and lifetime during sonication dominant role of secondary cavitation bubbles causing acoustic bioeffects.

Acoustic cavitation has been shown to deliver molecules into viable cells, which is of interest for drug and gene delivery applications. To address mechanisms of these acoustic bioeffects, this work measured the lifetime of albumin-stabilized cavitation bubbles (Optison) and correlated it with desirable (intracellular uptake of molecules) and undesirable (loss of cell viability) bioeffects. Optison was exposed to 500 kHz ultrasound (acoustic pressures of 0.
