Data from the Italian Ministry of Health show that approximately 300-500 per 100.000 Italians are admitted to hospital each year for either TBI or subarachnoid haemorrhage with an annual mortality of 20 per 100.000; 90% of these TBI are of medium severity. Traumatic brain injury-induced hypopituitarism in adults are more common than previously thought. The paucity of clinical reports relating to adolescents with past-TBI induced hypothalamic-pituitary-dysfunction suggests that this phenomenon might be less common that that observed in adults. In the last 25 years, in our Unit a pituitary dysfunction was established during childhood and adolescence in 3 patients (one patient had a precocious puberty, one patient had a gonadal dysfunction and one patient had a partial growth hormone deficiency). In all patients the TBI was severe (unpublished data, 2008). The physiopathological basis of hypopituitarism is lacking. Nevertheless, necrotic, hypoxic, ischemic and shearing lesions are at the hypothalamus and/or the pituitary are likely important factors. The subjects at highest risk appear to be those who have suffered a moderate or severe trauma. Clinical signs of anterior hypopituitarism are often subtle and may be masked by sequalae of TBI. Therefore, post-traumatic anterior pituitary dysfunction may remain undiagnosed and, possibly, aggravate symptoms of brain injury. Moreover it may, if undiagnosed, lead to potentially fatal endocrine crisis. Therefore, adolescents with moderate-severe traumatic brain injury should be screened for such endocrine deficiencies so that replacement therapy can be initiated to optimized the rehabilitation and outcome.
