A pilot study on the anticonvulsive effects of a thyrotropin-releasing hormone analog in intractable epilepsy.

In 1981, Inanaga et al reported on the efficacy of DN-1417 (a TRH analog) in the treatment of degenerative myoclonus epilepsy and other forms of intractable epilepsy. Following this report, we studied the efficacy and safety of DN-1417 treatment in 10 intractable epileptic children ranging in age from 6 months to 11 years (mean 4 years), including 7 with Lennox syndrome (LS), 2 with West syndrome (WS) and 1 with degenerative myoclonus epilepsy (DME). The daily dose was from 0.02 to 0.05 mg/kg, initially, and then was increased to 0.05 mg/kg. Complete control of seizures was achieved in 2 patients with LS, a 50% or greater decrease in seizure frequency was observed in one patient each with LS and DME and a less than 50% decrease in 1 with LS and 2 with WS. There was no change in 2 LS cases, and 1 LS case became worse. Activation of psychic activities, such as psychomotor activity, facial expression and motivation, was also noted in 7 of the 10 patients. Furthermore, improvement of motor function was noted in 5 patients. Electroencephalographic abnormalities improved in 2 completely seizure free patients with LS in which EEG ameliorated along with clinical seizure control.

A case of Isaacs syndrome with high CSF protein and a large cisterna magna.

An 11-year-old boy exhibited continuous muscle fiber activity. He had suffered from stiffness of his hands, difficulty in relaxing his hands after gripping, and making skilled movements with his fingers. His clinical symptoms improved after treatment with carbamazepine. Electromyography (EMG) showed that he had continuous electrical discharges both at rest and during sleep. These discharges completely disappeared after the peripheral nerve was blocked with Lidocaine. An evoked electromyogram showed suppression of abnormal discharges after the F response. These electrophysiological findings indicated that the disorder originated in the spinal anterior horn cells. CT scanning showed a large cisterna magna in the posterior cranial fossa. Protein in the cerebrospinal fluid was elevated.

Fragile X syndrome in Japanese patients with infantile autism.

Forty-seven patients (39 boys and 8 girls) with infantile autism whose clinical symptoms had matched the diagnostic criteria of DSM III were studied cytogenetically for the occurrence of fragile X [fra(X)] syndrome. The existence of fra(X) chromosome in these patients was screened first by culturing peripheral blood lymphocytes in a medium in which folic acid was absent; the fra(X) chromosome then was confirmed by reculturing in another medium to which 5-fluoro-2'-deoxyuridine was added for the last 24 hours of culture. Fra(X) chromosome was found in 2 of 39 male patients, but in none of the female patients; the 2 patients are siblings. Thus, fra(X) syndrome occurs in 2.6% (1/38) in this study population of male autistic children. The frequencies of fra(X) expression in the older brother with mild mental retardation, in the more severely retarded younger brother, and in their mother were 3-5%, 17-20%, and 9-3%, respectively. Of the two methods used in the present study, the method employing 5-fluoro-2'-deoxyuridine tended to be more sensitive to fra(X) chromosome detection, especially for a suspected carrier.
