Case Reports
Reversible language regression as an adverse effect of topiramate treatment in children.
Profound language regression developed in three children with epilepsy 4 to 28 weeks after beginning topiramate (TPM). TPM was administered as an adjunctive antiepileptic drug at doses of 2.5 to 6.0 mg/kg/day. Language functions recovered while TPM was being reduced in dose or stopped.

Randomized Controlled Trial Multicenter Study Clinical Trial
Unilateral pallidotomy versus bilateral subthalamic nucleus stimulation in PD: a randomized trial.
To compare the efficacy of unilateral pallidotomy and bilateral subthalamic nucleus (STN) stimulation in patients with advanced Parkinson disease (PD) in a randomized, observer-blind, multicenter trial. ⋯ Bilateral STN stimulation is more effective than unilateral pallidotomy in reducing parkinsonian symptoms in patients with advanced PD.

Randomized Controlled Trial Comparative Study Clinical Trial
Systemic lidocaine in pain due to peripheral nerve injury and predictors of response.
To investigate the effects of IV lidocaine on spontaneous and evoked pain (allodynia and hyperalgesia) due to peripheral nerve injury (postherpetic neuralgia or nerve trauma) using quantitative sensory testing. ⋯ These data indicate modality-specific antihyperalgesic effects of IV lidocaine in patients with peripheral nerve injury. Patients with mechanical allodynia may be good candidates for treatment with local anesthetic-like drugs and possibly with other sodium-channel blockers.

Randomized Controlled Trial Clinical Trial
Valproic acid has no effect on pain in polyneuropathy: a randomized, controlled trial.
The aim of this randomized, double-blind, placebo-controlled cross-over study was to test whether valproic acid relieves painful polyneuropathy. Thirty-one patients completed two treatment phases of 4 weeks' duration with valproic acid (1,500 mg daily) and placebo. There was no significant difference between valproic acid and placebo in the rating of total pain (median, 5 in the valproic acid period vs 6 in the placebo period; p = 0.24) or in individual pain ratings.
