Trial of an ACTH4-9 Analogue (ORG 2766) in children with intractable seizures.

The ACTH4-9 Analogue (ORG 2766) is an orally administered neuropeptide which has been showed to have behavioral effects in human subjects, but does not have any steroidogenic effects, nor other significant side effects. This study was a double-blind, crossover trial of the ACTH4-9 analogue in four children with intractable seizures. There was some slight improvement in seizure frequency in two patients, with an equivocal improvement in a third child. A fourth child was unchanged, while the fifth dropped out of the study. There were no side effects from the therapy. This questionable improvement in seizure frequency in some of the most intractable patients with seizure disorders indicates the need to further assess this ACTH4-9 analogue in a larger study over a longer period of time.

Pemoline-induced Tourette's disorder: a case report.

The author describes the case of a 14-year-old boy who developed Gilles de la Tourette's disorder during pemoline therapy. Unlike other reported cases, the boy's tics did not remit after the pemoline was discontinued.

Cursive and gelastic epilepsy: case report.

A child with cursive and gelastic epilepsy is reported. This particular case in unique in that the patient had no underlying neurological disease, his running and laughing seizures represented his only seizure type; and recorded ictal episodes originated bilaterally and anteriorly.

Associative learning in premature hydranencephalic and normal twins.

A hydranencephalic infant lacking cerebral hemispheres and a normal twin were tested for associative learning. After repeated trials in which two stimuli were temporally paired, test trials were given in which the second stimulus was omitted. Cardiac orienting responses to stimulus omission indicated that learning had taken place in both infants.

Congenital anophthalmia associated with intracranial germinoma.

A 14-year-old boy with anophthalmia presented evidence of hypothalamic dysfunction. He was found to have a third-ventricular germinoma, probably pineal. This case is interesting in view of a previous case report of the association of anophthalmia and a germ-cell tumor (teratoma), and suggests a possible causal relationship between this malformation and germ-cell neoplasms, bith of which probably arise early in development.

Fatal long-term sequela following radiation "cure" for ependymoma.

There are no previous reports of glioblastoma occurring following central nervous system irradiation. This report describes a young girl with an ependymoma at age 13 months who was treated by radiotherapy following surgical removal. At age 6 years she presented with a new lesion in the same location. Histologically there was no evidence of recurrent ependymoma. Instead, the pathological picture suggested glioblastoma or a severe radiation-induced encephalopathy. In either case, it seems likely that the changes were radiation induced.

Long-term treatment of juvenile Huntington's chorea with dipropylacetic acid.

Since the proposed mode of action of dipropylacetic acid, an anticonvulsant, is to increase central nervous system gamma-aminobutyric acid levels, we used this agent to treat identical twins with juvenile Huntington's chorea. Their clinical status did not improve immediately after they received dipropylacetic acid. Furthermore, long-term administration (over a year) of high doses of the agent (up to 2,400 mg per day; 92 mg per kilogram per day) did not seem to alter the slow progression of their disease. Prior to treatment with dipropylacetic acid, the twins had normal cerebrospinal fluid gamma-aminobutyric acid levels. In addition, cerebrospinal fluid 5-hydroxyindoleacetic acid and homovanillic acid were determined before and after 18 hours of high-dose probenecid. The former showed a normal threefold to fourfold increase after probenecid administration, but homovanillic acid had a distinctly subnormal turnover after probenecid, with only a threefold rather than the normal tenfold increase.

Computerized axial tomography in neurologic disorders of children.

Computerized axial tomography offers major advantages over air encephalography and angiography for studies of neurologic disorders in children. The low morbidity and the ease of the procedure permit the accurate diagnosis of intracranial pathology in situations where more invasive procedures would not be undertaken. The techniques of the procedure and its uses and limitations are emphasized in a number of neurologic problems of children.

Spontaneous improvement in "normal" pressure hydrocephalus.

A patient is presented with "normal" pressure hydrocephalus including dementia, incontinence, and apraxic gait. He had a normal lumbar CSF pressure, hydrocephalus with lack of air over the convexities on pneumoencephalography, and ventricular filling with prolonged retention on cisternography. He did not receive a shunt and, nevertheless, showed spontaneous improvement in his mental function over the next few years. This cases emphasizes the necessity for a controlled study of shunting for "normal" pressure hydrocephalus.
