To determine clinical signs that can predict pneumonia (confirmed by radiography) in infants under 2 months of age, 101 infants with pneumonia and 150 with an upper respiratory infection (but not pneumonia) were studied. Ten infants with pneumonia and 15 with an upper respiratory infection did not have the cough and/or difficult (or rapid) breathing that are recommended as 'entry criteria' by the World Health Organisation (WHO). The remaining infants met WHO entry criteria; in them sensitivity and specificity of respiratory rate > or = 60/min and/or severe chest indrawing to diagnose pneumonia was 85% and 97% respectively. ⋯ However, the non-specific signs were the only clue to diagnosis in five infants weighing < or = 2500 g. At age < 7 days, a weight < or = 2500 g and cyanosis were associated with significantly higher risk of mortality. These findings support the use of a respiratory rate > or = 60/min and/or chest indrawing for identification of pneumonia, and suggest addition of nasal flaring to the criteria for case identification in infants under 2 months with cough and/or difficult or rapid breathing.

Nine patients with central hypoventilation syndrome (CHS) were treated with negative extrathoracic pressure ventilation (VNEP). Treatment with VNEP was started between 20 days and 57 months of age, which was two days to 47 months after diagnosis. The equipment to provide VNEP utilised a new system with a latex neck seal and Perspex chamber allowing easy access to the child. ⋯ VNEP is an effective, non-invasive, treatment in infants with CHS if initiated before tracheostomy. It may improve the children's quality of life during the daytime. If upper airway obstruction is a problem in the first year of life, it may be combined with nasal mask CPAP.
