AIM To demonstrate that hyperprolactinaemia and/or prolactinoma occur in association with antipsychotic medication use. METHODS Three case studies of patients with markedly elevated serum prolactin level (>132 microg/l); either antipsychotic medication induced or as a consequence of a prolactinoma. CONCLUSION The management and investigation of children with markedly elevated serum prolactin levels remains poorly defined. In our case series, two patients were found to have prolactinomas. We suggest that paediatric patients with serum prolactin level above 50 microg/l in males and 70 microg/l in females, regardless of any antipsychotic medication use, receive magnetic resonance imaging to exclude prolactinoma.

Hearing losses in children are disabling and frequently unrecognized. Children with persistent uncorrected hearing impairment are at high risk for speech and language delays, behavioural problems, and socialization and learning difficulties. Although most hearing impairment in childhood is conductive in type. about 1 in 1000 Australian children have significant sensorineural hearing losses (SNHL) of mild to profound degree.
