CICADA: Cough in Children and Adults: Diagnosis and Assessment. Australian cough guidelines summary statement.

Cough is a common and distressing symptom that results in significant health care costs from medical consultations and medication use. Cough is a reflex activity with elements of voluntary control that forms part of the somatosensory system involving visceral sensation, a reflex motor response and associated behavioural responses. At the initial assessment for chronic cough, the clinician should elicit any alarm symptoms that might indicate a serious underlying disease and identify whether there is a specific disease present that is associated with chronic cough. If the examination, chest x-ray and spirometry are normal, the most common diagnoses in ADULTS are asthma, rhinitis or gastro-oesophageal reflux disease (GORD). The most common diagnoses in CHILDREN are asthma and protracted bronchitis. Management of chronic cough involves addressing the common issues of environmental exposures and patient or parental concerns, then instituting specific therapy. In ADULTS, conditions that are associated with removable causes or respond well to specific treatment include protracted bacterial bronchitis, angiotensin-converting enzyme inhibitor use, asthma, GORD, obstructive sleep apnoea and eosinophilic bronchitis. In CHILDREN, diagnoses that are associated with removable causes or respond well to treatment are exposure to environmental tobacco smoke, protracted bronchitis, asthma, motor tic, habit and psychogenic cough. In ADULTS, refractory cough that persists after therapy is managed by empirical inhaled corticosteroid therapy and speech pathology techniques.

Occurrence and management of acute respiratory illnesses in early childhood.

AIM: Acute respiratory illnesses (ARI) impose massive economic burden on health services. The growing costs, limited benefits of pharmacotherapeutic agents, and alarming rise in antibiotic resistance poses a major health challenge. Analysis of the nature and burden of ARI through well-designed epidemiologic studies will help in the development of a uniform public health approach to identify methods to reduce disease transmission and maximise prevention strategies. The aim of this study was to analyse the nature and magnitude of the burden of ARI encountered by a cohort of children in the first 5 years of life. METHODS: This community-based prospective study of ARI followed a cohort of children from birth until 5 years of age. Information on all episodes of ARI encountered, and their management, was collected through daily symptom diary and fortnightly telephone calls. RESULTS: Four episodes of ARI/year were reported in the first 2 years and 2-3 episodes/year between 2 and 5 years. The majority were upper respiratory infections. 53% had at least one lower respiratory infection in the first year. For the majority, symptoms lasted 1-2 weeks. 53% were treated with antitussives or cough mixtures, 44% with paracetamol and 23% with antibiotics. A total of 46% of the episodes presented to a family physician, with younger children and those with lower respiratory infection more likely to seek attention. CONCLUSION: ARI are common in childhood and although symptoms may last for 4 weeks, the majority resolve spontaneously. Use of medication does not appear to significantly alter the course or duration of symptoms of ARI.
