BACKGROUND: Stiripentol is an inhibitor of cytochrome P450 that showed antiepileptic efficacy in severe myoclonic epilepsy in infancy (SMEI) in association with clobazam and valproate in an open study. To confirm these results, 41 children with SMEI were included in a randomised, placebo-controlled, add-on trial. METHODS: After a baseline period of 1 month, placebo (n=20) or stiripentol (n=21) was added to valproate and clobazam during a double-blind period of 2 months. Patients then received stiripentol in an open fashion. Responders were defined as having more than 50% reduction in the frequency of clonic (or tonic-clonic) seizures during the second month of the double-blind period compared with baseline. FINDINGS: 15 (71%) patients were responders on stiripentol (including nine free of clonic or tonic-clonic seizures), whereas there was only one (5%) on placebo (none were seizure free; stiripentol 95% CI 52.1-90.7 vs placebo 0-14.6). The 95% CI of the difference was 42.2-85.7. Percentage of change from baseline was higher on stiripentol (-69%) than on placebo (+7%), p<0.0001. 21 patients on stiripentol had moderate side-effects (drowsiness, loss of appetite) compared with eight on placebo, but side-effects disappeared when the dose of comedication was decreased in 12 of the 21 cases. INTERPRETATION: This controlled trial shows the antiepileptic efficacy, of add-on stiripentol in children with SMEI. The results also provide good reason to focus studies on a specific epilepsy syndrome-a small sample of patients is sufficient to show the efficacy that might have been missed in a heterogeneous population.

Patients with generalized anxiety disorder experience worry or anxiety and a number of physical and psychologic symptoms. The disorder is frequently difficult to diagnose because of the variety of presentations and the common occurrence of comorbid medical or psychiatric conditions. The lifetime prevalence is approximately 4 to 6 percent in the general population and is more common in women than in men. It is often chronic, and patients with this disorder are more likely to be seen by family physicians than by psychiatrists. Treatment consists of pharmacotherapy and various forms of psychotherapy. The benzodiazepines are used for short-term treatment, but because of the frequently chronic nature of generalized anxiety disorder, they may need to be continued for months to years. Buspirone and antidepressants are also used for the pharmacologic management of patients with generalized anxiety disorder. Patients must receive an appropriate pharmacologic trial with dosage titrated to optimal levels as judged by the control of symptoms and the tolerance of side effects. Psychiatric consultation should be considered for patients who do not respond to an appropriate trial of pharmacotherapy.
