Paediatric respiratory reviews

Significant morbidity and mortality from smoke inhalation occurs in victims of fire. Lung injury can be caused by chemical and thermal insults. A variety of noxious gases, irritants and asphyxiants are generated depending on the material burnt. ⋯ There is no evidence that the routine use of corticosteroids or prophylactic antibiotics is beneficial. Through a better understanding of the pathophysiology of smoke-induced lung injury, the effects of exogenous surfactant, leukotriene inhibitors, antioxidants, nitric oxide synthase inhibitors and fibrinolytics suggest that these compounds may have a future therapeutic role in smoke-induced injury. Studies are needed to evaluate the safety and efficacy of these potential therapies before they are used clinically.

This article describes some of the challenges that face trainers and trainees in medical education. There are ethical issues surrounding the use of real patients - particularly children and young people. How much can a young trainee "practise" on a patient? How can they best learn practical skills or gain experience of intimate examinations? The requirements of professional behaviour of trainers towards trainees and of both towards patients are described. Patients involvement in teaching, assessment and formal examinations is discussed.

Pneumonia is one of the most common global childhood illnesses. The diagnosis relies on a combination of clinical judgement and radiological and laboratory investigations. Streptococcus pneumoniae remains the most important cause of childhood community-acquired pneumonia. ⋯ In the minority of cases only, the actual organism is isolated to guide treatment. Antibiotics effective against the expected bacterial pathogens should be instituted where necessary. The route and duration of antibiotic therapy, the role of emerging pathogens and the impact of pneumococcal resistance and conjugate pneumococcal vaccines are also discussed.

An understanding of the physiological processes underlying respiratory function in the healthy individual is essential in recognising and understanding disease processes. Departure from the normal pattern of tidal breathing is an early and reliable sign of respiratory disease. ⋯ Respiratory signs and symptoms are based on alterations of normal physiology by the disease process. Unfortunately, these basic principals are rarely emphasised in current teaching programs.
