To examine serum cortisol responses to a simplified low-dose short Synacthen test (LDSST) in children treated with inhaled corticosteroids (ICS) for asthma and compare these early morning salivary (EMSC) cortisone (EMSCn) levels.Early EMSCn samples were collected three consecutive days. On day three, 500 ng/1·73 m(2) was administered intravenously. Samples at 0, 15, 25, 35 min.A total of 269 subjects (160 M: 109 F), median (range) age 10·0 (5·1-15·2) years studied. Peak the LDSST <500 nmol/l...

Extra-intestinal or metastatic Crohn9s disease is being recognised increasingly, most commonly in the skin and genitourinary system. Only very rarely has it been reported lung. A 3 year old boy who presented with swollen gums a persistent abnormality on his chest x ray reported. Lung biopsy specimens showed multiple non-caseating epithelioid granulomas. Subsequent investigation presence of intestinal disease. The evidence for abnormal lung function possible pathogenesis pulmonary are discussed.

In hospital, staff need to routinely monitor patients identify those who are seriously ill, so that they receive timely treatment improve their condition. A Paediatric Early Warning System is a multi-faceted socio-technical system detect deterioration in children, which may or not include track and trigger tool. It functions monitor, prompt an urgent response signs of deterioration, with the aim preventing morbidity mortality. The purpose this study develop evidence-based improvement...

Paediatric mortality rates in the United Kingdom are amongst highest Europe. Clinically missed deterioration is a contributory factor. Evidence to support any single intervention address this problem limited, but cumulative body of research highlights need for systems approach. An evidence-based, theoretically informed, paediatric early warning system improvement programme (PUMA Programme) was developed and implemented two general hospitals (no onsite Intensive Care Unit) tertiary (with...

Bronchiolitis is an acute lower respiratory infection which predominantly affects young children. Treatment for bronchiolitis limited to supportive therapy. Nasal oxygen therapy part of routine care, and delivery now incorporates varying levels non-invasive continuous positive airway pressure and/or high-flow nasal cannula Despite wide clinical use, there remains a lack evidence on the comparative effectiveness safety these interventions. Furthermore, research in this field hampered by use...
