A retrospective study of patient outcomes and satisfaction following pinnaplasty.

Introduction: Up to 5% of all children have prominent ears. Psychological distress and bullying adversely affect these children and can cause significant social exclusion. In times of austerity, cosmetic procedures such as surgical correction of prominent ears are felt to be an unnecessary cost to the health service.

Separation of statistical poly[(N-vinyl pyrrolidone)-co-(vinyl acetate)]s by reversed-phase gradient liquid chromatography.

Although size exclusion chromatography (SEC) has been used successfully to determine the molecular weight distribution (MWD) of statistical poly[(N-vinyl pyrrolidone)-co-(vinyl acetate)]s [PVPVAs], SEC cannot separate the copolymers according to their chemical composition. In this article, the separation of commercial PVPVAs with varying chemical compositions is reported, by aqueous reversed-phase gradient liquid chromatography (RPLC) using polystyrene-divinylbenzene-based wide pore columns. RPLC-SEC cross-fractionation indicates the presence of molar mass dependant effects during RPLC separation due to broad MWD for the copolymer studied; therefore the width of the RPLC peak could not be associated entirely with chemical composition distribution of the copolymer.

Recovered, in recovery or recovering from substance abuse? A question of identity.

There has always been widespread debate on how people with past substance abuse problems choose to identify themselves with regards to their recovery and the terms used to associate with that identity. Most of the disagreement over these terms is rooted on whether recovery is seen as an ongoing process ("recovering" or "in recovery") or a life event that can be mastered ("recovered"). This article discusses these three controversial terms and attempts to make them available as terms that one can use or identify with by presenting different perspectives on the topic of recovery.

Severe influenza B myocarditis and myositis.

Objective: To report an influenza B infection with associated myocarditis and severe skeletal myositis.

Design: Case report.

Setting: Cardiac intensive care unit in a university-affiliated children's hospital.

Iron supplementation increases disease activity and vitamin E ameliorates the effect in rats with dextran sulfate sodium-induced colitis.

Inflammatory bowel disease is often associated with iron deficiency anemia and oral iron supplementation may be required. However, iron may increase oxidative stress through the Fenton reaction and thus exacerbate the disease. This study was designed to determine in rats with dextran sulfate sodium (DSS)-induced colitis whether oral iron supplementation increases intestinal inflammation and oxidative stress and whether the addition of an antioxidant, vitamin E, would reduce this detrimental effect.
