    ABSTRACT: We report our experience on the duration of effectiveness of botulinum toxin A injections to the upper extremities of children with cerebral palsy. A retrospective chart review was conducted on 30 consecutive patients (mean age, 9.9 ± 5.0 years) with spastic hemiparesis and quadriparesis. They received 1 to 5 treatments, totaling 56 treatments for the entire cohort. The injected muscles were the pronator teres (50/56), flexor carpi radialis (39/56), biceps (38/56), flexor carpi ulnaris (35/56), opponens (21/56), and adductor pollicis (17/56). Children were assessed for muscle tone and classified according to the Manual Ability Classification System before and after treatment. Functional improvement was apparent after 42 of 56 treatments, and muscle tone decreased significantly (P < .001). The mean duration of the effect was 7.0 ± 3.0 months. We conclude that the effect of botulinum toxin A to the upper limbs is retained for longer periods of time than those reported for lower limbs.

    ABSTRACT: To describe the clinical spectrum and to evaluate the efficacy of different therapeutic agents in children with electrical status epilepticus in sleep (ESES). Clinical data of all patients with ESES (not including patients with Landau-Kleffner syndrome) in four pediatric neurology outpatient clinics were analyzed. Thirty patients with ESES had been treated between 1994 and 2007. Eleven (37%) children had benign partial epilepsies of childhood, five (17%) had cerebral palsy, five (17%) had hydrocephalus, one (3%) had schizencephaly, one (3%) had prenatal parenchymal bleeding, and the etiology was unclear in seven (23%). The duration of ESES ranged between 2 and 60 months. The antiepileptic drugs that were found to be efficacious were: levetiracetam (41%), clobazam (31%), and sulthiame (17%). Valproic acid, lamotrigine, topiramate, and ethosuximide showed no efficacy. Steroids were efficacious in 65%; immunoglobulins were efficacious in 33%. High-dose diazepam was efficacious in 37%, but all the children had temporary response. Seventeen patients (57%) had cognitive deterioration, whereas the rest presented with regression in attention, speech, communication, and behavior. Fourteen children had permanent cognitive deficit. There was a significant correlation (p = 0.029) between the duration of ESES and residual intellectual deficit at follow-up. ESES reflects an evolution of benign partial epilepsy of childhood in more than one-third of the patients, whereas there is an underlying structural brain anomaly in another one-third. The most efficacious antiepileptic drugs (AEDs) are levetiracetam and clobazam. The duration of ESES correlated significantly with residual intellectual deficit at follow-up.
