Abstract Background Endoscopy is essential for measuring luminal disease activity in Crohn’s (CD). Current endoscopic indices evaluating CD are limited: they only modestly correlated with activity, contain items that ambiguously defined and have poor inter-observer reliability, lack validated definitions clinically relevant change. We aimed to develop internally externally validate a reliable responsive index. Methods In this multi-part study, candidate index development face validity...

We aimed to examine the associations between exposure air pollution and outcomes of preterm birth (PTB), term low weight (TLBW), small for gestational age.We conducted a population-based cohort study using perinatal database linked land-use regression-modeled data.Compared with women in lowest quartile toluene exposure, those second showed positive association PTB (odds ratio = 1.35, 95% confidence interval: 1.12, 1.63). A piecewise logistic regression breakpoint analysis identified cut...

Abstract Seventeen children at six institutions with neurofibromatosis type 2 (NF2)‐related vestibular schwannomas received bevacizumab. Eight of the 13 patients initial hearing loss (61%) showed objective improvement within months treatment. No deterioration during therapy; however, only two radiological response. Seven eight had tumor progression or worsening upon cessation Bevacizumab was well tolerated no discontinuing therapy. appears to postpone in childhood NF2‐associated schwannomas,...

Body mass index (BMI) is commonly used to assess a child's weight status but it does not provide information about the distribution of body fat. Since disease risks associated with obesity are related amount and fat, measures that visceral or subcutaneous such as waist circumference (WC), waist-to-height ratio (WHtR), skinfolds thickness may be more suitable. The objective this study was develop percentile curves for BMI, WC, WHtR, sum 5 (SF5) in representative sample Canadian children...
