Management of acute viral bronchiolitis is largely supportive. There is currently no proven effective therapy other than oxygen for hypoxic children. The evidence indicates that there is no routine benefit from inhaled, rapid short-acting bronchodilators, adrenaline or ipratropium bromide for children with acute viral bronchiolitis. ⋯ Prophylaxis should be commenced at the start of the RSV season and given monthly during the season. The development of an RSV vaccine may offer a more effective alternative to prevent disease, for which the results of clinical trials are awaited. Education of parents or caregivers and healthcare workers about diagnostic and management strategies should include the following: bronchiolitis is caused by a virus; it is seasonal; it may start as an upper respiratory tract infection with low-grade fever; symptoms are cough and wheeze, often with fast breathing; antibiotics are generally not needed; and the condition is usually self limiting, although symptoms may occur for up to four weeks in some children.

Continued effort and politcal will must be directed towards preventing, delaying the onset of and managing non-communicable diseases in South Africa.

Bronchiolitis may be diagnosed on the basis of clinical signs and symptoms. In a young child, the diagnosis can be made on the clinical pattern of wheezing and hyperinflation. Clinical symptoms and signs typically start with an upper respiratory prodrome, including rhinorrhoea, low-grade fever, cough and poor feeding, followed 1 - 2 days later by tachypnoea, hyperinflation and wheeze as a consequence of airway inflammation and air trapping. ⋯ Routine measurement of C-reactive protein does not aid in management and nasopharyngeal aspirates are not usually done. Viral testing adds little to routine management. Risk factors in patients with severe bronchiolitis that require hospitalisation and may even cause death, include prematurity, congenital heart disease and congenital lung malformations.

Abnormal mediastinal air may be caused by inhalational illicit drug use subsequent to barotrauma resulting from coughing after deep inhalation and breath holding. It may also arise from oesophageal rupture due to retching after ingestion of the illicit drug. ⋯ As chest radiographs are widely accessible and mediastinal air is easily recognisable, the chest radiograph should be included and carefully scrutinised in the diagnostic workup of chest pain in the recreational drug abuser. It is prudent to exclude oesophageal rupture, particularly in the setting of retching, before deciding on conservative and expectant management.
