Drugs used to treat cardiovascular disease as well as those used in the treatment of multiple other conditions can occasionally produce exaggerated prolongation of the QT interval on the electrocardiogram and the morphologically distinctive polymorphic ventricular tachycardia ('torsades de pointes'). This syndrome of drug-induced long QT syndrome has moved from an interesting academic exercise to become a key element in the development of any new drug entity. The prevailing view, which has driven both clinical care and drug regulation, holds that cardiac repolarization represents a balance between inward currents (primarily through calcium and sodium channels) and outward currents (primarily through rapid and slowed delayed rectifier potassium channels) and that block of the rapid delayed rectifier (IKr ) is the primary mechanism whereby drugs prolong individual action potentials, manifest on the surface electrocardiogram as QT interval prolongation...

OBJECTIVES & BACKGROUND: Unplanned paediatric admissions are increasing for young children and infants experiencing respiratory illnesses. Many admissions are short-stay events, typically lasting less than 48 hrs. The short duration of these admissions could indicate that minor conditions are responsible for many of these events, and could consequently be targets for management by primary care teams. The purpose of this exploratory qualitative research is to understand more about admissions in young children attending the emergency department of a Children's hospital in the UK, with the aim of collaboratively identifying interventions to reduce admissions for minor respiratory conditions...
