Abstract
Neuro-endocrine disorders are a frequent complication of head trauma. The exploration of these disturbances is important because it can contribute to the understanding of some symptoms presented by the patients for better management in the acute phase or during the evolution.
Aim: The objective of this study was to identify the anterior pituitary dysfunction of severe traumatic brain injury and to analyze the correlations between these disorders, brain lesions and clinical signs.
Materials and Methods: This is a prospective and descriptive study, conducted in collaboration between the pediatric intensive care unit and the clinical biochemistry laboratory of the Mohammed VI University Hospital of Marrakech. This study was spread over 9 months. It Included children admitted for severe head trauma and with a clinical, hormonal and CT scan. And the interest was in 28 severely traumatized skulls in the acute phase. All patients received TSH, T3, T4, Prolactin and cortisol levels 8 hours after admission.
Results: There were twenty eight patients included in the study. Sex ratio m / f of 1.54, whose age varies between 9 months and 14 years, with an average age of 6.5 years. Half of the patients had an initial Glasgow score of 8/15. This was cerebral oedema in (46.42%) cases. In this study, the rate of endocrine disorders was 85.71%, the exploration of the thyrotropic axis proved normal in all of these patients. Low cortisol levels were observed in 11% of cases, 67.84% of children had hyperprolactinemia. One-third of the patient included in the study had 2-axis involvement, namely cortisol and prolactin. Half, on the other hand, showed only one axis.
Conclusion: In the aftermath of head trauma, pituitary disturbances are frequent and should be included in their management.
