Glow flow ionization mass spectrometry of small molecules. A comparison of a glow flow ionization source ('GlowFlow') with electrospray ionization and atmospheric pressure chemical ionization.

Rationale: Ionization by atmospheric pressure gas discharge has been employed for a long time in mass spectrometry. Inductively coupled plasma mass spectrometry is an exemplar, and widely used for elemental analysis. The technique has less uptake in organic mass spectrometry.

Recurrent myocarditis is rare with only few reports having been published for paediatric cases. Repeated use of extracorporeal membrane oxygenation is also uncommon. In this paper we will present a very rare case of a 7-year old girl with recurrent fulminant myocarditis with heart failure requiring cardiopulmonary resuscitation and mechanical circulatory support with extracorporeal membrane oxygenation.

Aortic valve regurgitation following percutaneous closure of patent ductus arteriosus.

Objectives: To determine the incidence and outcome of aortic valve regurgitation (AR) following the percutaneous closure of patent ductus arteriosus (PDA).

Background: Aortic valve regurgitation is an overlooked consequence of percutaneous PDA closure.

Methods: Between December 2000 and May 2009, 51 children underwent percutaneous closure of PDA using Amplatzer Duct Occluders.
