Don't test, do sell: legal implications of inclusion and exclusion of women in clinical drug trials.
This article explores the historic underpinnings of the exclusion of women from clinical drug trials, identifies recent developments, and examines legal implications for women with epilepsy and for others. Distinguishing stakeholders and their interests may lead to policies that better serve all. Past and present statutory, regulatory, and judicial frameworks were reviewed, as well as legal, medical, and historical commentary. ⋯ At this time the most effective shields will involve procurement of informed consent as well as testing of both women and men. In the long run, tort, health care, and regulatory reform will best serve all interested persons. Inclusion of women in clinical drug trials has become a how question, not an if one.

Clinical Trial
Steady-state pharmacokinetics of topiramate and carbamazepine in patients with epilepsy during monotherapy and concomitant therapy.
We studied the steady-state pharmacokinetic profile of topiramate (TPM) as a function of dose and the effects of comedication with carbamazepine (CBZ). ⋯ When CBZ is reduced or discontinued, TPM doses may need to be lowered to maintain equivalent plasma concentrations. Adjusting the CBZ dose for pharmacokinetic reasons when TPM is administered as adjunctive treatment does not appear to be necessary.

We report 12 infants who had frontal (n = 3), temporal (n = 2), or temporoparieto-occipital (n = 2) resection or functional hemispherectomies (n = 5) at age 2.5-29 (mean 15.3) months for catastrophic epilepsy due to focal cortical dysplasia (n = 5), Sturge-Weber syndrome (n = 3), ganglioglioma (n = 3), or hemimegalencephaly (n = 1). Seizures began at 1 day to 14 months (mean, 4.0 months) after birth, occurred frequently (often many times per day, and were refractory to antiepileptic drugs. Patients were evaluated for surgery at 2.5-24 (mean 12.4) months of age. Seven patients had hemiparesis and eight had slowed cognitive development. Seizures were characterized by arrest or marked reduction of behavioral motor activity with nuclear level of consciousness (n = 4, with temporal or temporoparietal EEG seizures), focal clonic activity (n = 3, with perirolandic EEG seizures), generalized tonic stiffening (n = 3, with temporoparieto-occipital, parietal, or frontal EEG seizures), or infantile spasms and hypsarrhythmia (n = 2, with a frontal tumor or temporoparieto-occipital cortical dysplasia). ⋯ Our results agree with previous reports that epilepsy surgery can provide relief from catastrophic epilepsy in carefully selected infants.

The study reviewed emergent cases of nonconvulsive status epilepticus (NCSE) to evaluate causes of diagnostic and management delay and examined frequent diagnostic features suggestive of NCSE. ⋯ NCSE often goes unrecognized or is mistaken for behavioral or psychiatric disturbance. The pleomorphic clinical presentation of NCSE indicates that EEG and a therapeutic trial of AEDs afford the best diagnostic measures in acute waxing and waning confusional states associated with agitation, bizarre behavior, staring, increased tone, mutism, or subtle myoclonus.
