Perspectives of French adolescents with ADHD and child and adolescent psychiatrists regarding methylphenidate use.

Many studies have demonstrated the short-term efficacy and tolerability of methylphenidate treatment adolescents with attention deficit hyperactivity disorder (ADHD). Qualitative literature on this matter focused on school outcomes, long-term side effects, family conflicts, personality changes and stigmatization. Yet, no qualitative study has crossed the perspectives of child and adolescent psychiatrists (CAPs) prescribing methylphenidate and adolescents with ADHD.

[Late post-traumatic syringomyelia. Discussion apropos an atypical case].

Late post-traumatic syringomyelia is uncommon, the clinical signs appearing several years after severe trauma to the cervical spinal cord. It is due to progressive cavitation in the spinal cord. In the case reported here progress was atypical because there were no immediate neurological signs and the symptoms of syringomyelia developed only 3 weeks after injury.

[Multiple intracranial aneurysms associated with primary hyperaldosteronism].

Multiple intracranial aneurysms have been reported in association with polycystic disease of the kidney, brain tumor, pituitary adenoma and coarctation of the aorta. We report the association of multiple aneurysms with primary hyperaldosteronism due to bilateral adrenal hyperplasia in an 18 year old left-handed man who presented with subarachnoid hemorrhage and arterial hypertension. We report the excellent outcome of this patient in spite of a difficult and surgical management.

CSF sulfoconjugated catecholamines in man: their relationship with plasma catecholamines.

Simultaneous plasma and cerebrospinal free and sulfoconjugated norepinephrine, epinephrine, dopamine and homovanillic acid determinations in 38 patients with various neurological disorders have shown consistently lower concentrations of dopamine sulfate, norepinephrine sulfate, and epinephrine sulfate in the cerebrospinal fluid than in plasma. An approximately three fold increase of plasma dopamine sulfate concentrations following banana ingestion did not result in increased dopamine sulfate concentrations in cerebrospinal fluid. There were positive correlations between plasma and cerebrospinal fluid concentrations of free norepinephrine and epinephrine as well as norepinephrine sulfate, dopamine sulfate and free homovanillic acid.
