BACKGROUND A relation between migraine with aura and cardiac right-to-left shunts has been reported. Right-to-left shunts are also associated with stroke and certain forms of decompression illness. We investigated the effect of closure of right-to-left shunts on migraine symptoms. METHODS A consultant neurologist, who was unaware of information about(More)
The presence of a large right-to-left shunt is associated with neurological decompression illness after non-provocative dives, as a result of paradoxical gas embolism. A small number of observations suggest that cutaneous decompression illness is also associated with a right-to-left shunt, although an embolic aetiology of a diffuse rash is more difficult to(More)
OBJECTIVE To compare the incidence and prognosis of subaortic stenosis associated with a ventricular septal defect and to define the morphological basis of subaortic stenosis. DESIGN Presentation and follow up data on 202 patients with subaortic stenosis seen at the Royal Liverpool Children's Hospital between 1 January 1960 and 31 December 1991 were(More)
BACKGROUND Nitric oxide is a potent dilator of the pulmonary vasculature. There have been no previous reports on the action of nitric oxide on the arterial duct. OBJECTIVES To determine the responses of isolated post-term arterial duct rings from lambs to oxygen, prostaglandin E2 (PGE2) and the nitric oxide donor, 3-morpholinosydnonimine (SIN-1). (More)
The systemic circulation of newborn infants with congenital left-heart obstruction is supplied from the right ventricle via a patent arterial duct between the pulmonary artery and descending aorta. The duct closes during the first few days of life, but infusion of prostaglandin E2 can prevent closure in some cases. We report four newborn infants (aged 3-8(More)
OBJECTIVE To investigate the spectrum of pulmonary atresia and critical pulmonary stenosis using right ventricular outflow tract angiography and explore its implications for catheter interventional treatment. DESIGN Prospective clinical study. SETTING Two paediatric cardiology centres. SUBJECTS 11 neonates or infants (aged 1 day to 8 months; weighing(More)
This paper presents a method for teaching undergraduate students how to write better term papers in philosophy. The method integrates two key assignment components: scaffolding and peer review. We explain these components and how they can be effectively combined within a single term paper assignment. We then present the results of our multi-year research(More)
A 14-year-old boy presented with a 3-year history of a skin rash typical of juvenile dermatomyositis, and a 2-month history of mild proximal weakness, myalgia, and weight loss. A quadriceps biopsy showed perifascicular fibre atrophy, focal necrosis and regeneration, immunohistochemical labelling for HLA-1 on the surface of the fibres, and focal C5-9(More)
