Three single CSF proteins with different molecular size (albumin, immunoglobulin G, and alpha2-macroglobulin) were determined by the method of electroimmunoassay in 61 children with febrile convulsions (FC) in order to evaluate the permeability of the blood-CSF barrier (B-CSF-B). Forty-two children with acute extracerebral infection served as controls. In contrast to a group of 22 children who suffered from acute meningoencephalitis or encephalitis, the CSF values of 48 children with FC were within normal limits. Thus even a very mild form of inflammatory encephalopathy-undetectable with conventional CSF investigation-was excluded in the majority of the children with FC. In 11 patients, however, CSF concentrations of albumin and alpha2-macroglobulin were abnormally raised, indicating a B-CSF-B distrubance. Elevated albumin values were found most frequently. In several children with FC lasting more than 20-30 min, B-CSF-B damage was probably caused by prolonged seizure activity since there is a linear correlation between albumin concentration and duration of convulsions. Several other factors known to raise the children's risk of developing epilepsy in later life were associated with the protein pattern of B-CSF-B disturbance in some of the children. In these cases, the cause of abnormal permeability of B-CSF-B is unknown and the condition might have existed prior to the occurrence of seizures.

Medulloblastoma and acute lymphocytic leukemia patients treated by intrathecal methotrexate and radiation were investigated by means of computerized axial tomography. More than 50% of them turned out to have acquired encephalopathy. Only gross morphologic brain defects, as visualized by computerized tomography, caused manifest clinical signs of brain dysfunction, such as epilepsy, mental retardation, paresis, and apallic syndrome. Mild morphologic changes were found even in asymptomatic children. The preferred site of defects in brain substance was the paraventricular white matter.

The record of 67 cases under 15 years of age who were hospitalized during status convulsivus from 1975 to 1978, the 348 cases who visited the hospital for the first time with epilepsy (Oct. 1977 to Sept. 1978) and the 32 cases who were hospitalized during status epilepticus from 1969 to 1974 and who are being followed up as outpatients were studied. The frequency of status epilepticus was 8% among epileptic children. There was no difference in the frequency of incidence between male and female. Patients with mental retardation, however, were revealed to have status epilepticus twice to three times more frequently as compared to cases without mental retardation. The major seizure types of status epilepticus in childhood were generalized tonic clonic convulsion and unilateral clonic convulsion. In 25% of the cases, status epilepticus was the first ictal manifestation. The major cause of status convulsivus was epilepsy, followed by encephalitis and encephalopathy, but cases due to brain tumor were rare. The drug of first choice for status convulsivus is diazepam. If there is any difficulty in controlling status convulsivus with diazepam, it may be worthwhile to consider what the problem is, causes of status convulsivus, seizure type, or basic disease of the patient. The effective dose of diazepam was within the range of 0.3--0.5 mg/kg. When the effect is not sufficient, the dose of diazepam should be increased to 1 mg/kg while watching the general condition of the patient. Factors affecting the prognosis of status convulsivus were its cause, duration, onset age and effectiveness of therapy during the acute stage. The frequency of cases who suffered disability after status epilepticus was 56%. (transient disability 43%, permanent disability 13%) The most frequent type of transient disability was hemiplegia. Most epileptic children who had repetitive status convulsivus revealed psychomotor retardation before first status. Factors which cause repetitive status seem to be hemispheric brain damage or diffuse corticocentrencephalic damage.

Neurological complications in the light of their clinical and topographical pattern are discussed with regard to the literature and 40 personal cases. Peripheral neuropathy is the most common (average frequency 26%). The main clinical, anatomical, histological and pathogenetic features of polyneuritis in diabetes are illustrated. Diabetic amyotrophy is a true clinical entity, though its site (neural or muscular) and pathogenesis are still the subject of discussion. Cranial nerve damage (oculomotor paralysis in particular) has the typical clinical, anatomical and histological picture of peripheral forms. Myelopathy leads to three distinct anatomical and clinical patterns: pseudo-tabes caused by degeneration of the roots and posterior cords; chronic anterior poliomyelitis due to degeneration of the cells of the anterior cornua; myelosis attributable to combined degeneration of the posterior and anterolateral cords. The main features of encephalopathy and the relation between epilepsy and diabetes are also examined.

Herpes simplex virus (HSV) encephalitis is an acute febrile encephalopathy usually characterized by disordered mentation, fever, headache, and focal seizures. We have described a patient with HSV encephalitis whose initial illness was manifested solely as a seizure disorder. Consequently, the diagnosis was not made until late in the hospital course. This atypical presentation of HSV encephalitis is emphasized to facilitate recognition of this disorder and to prompt early diagnostic brain biopsy so that appropriate antiviral therapy can be instituted.

Pharmacological prevention of epilepsy, especially in cases of past cranial trauma, arose as one of the problems connected with this disease. Attention has been called, however, ever more frequently to the neurotoxic effects of antiepileptic drugs symptoms and signs of with brain damage. Drug-induced encephalopathy or neuropathy occur particularly in patients with disorders of anticonvulsant drug metabolism in liver diseases or due to inborn enzymatic defects. Teratogenic and even epileptogenic side effects has been described in cases treated with therapeutic doses of anticonvulsants. The author discusses in this aspect the indications to pharmacological prevention of epilepsy quoting cases observed by her in which cranial trauma was followed by one or several seizures in early post-traumatic period and presence of seizure potentials was found in EEG. During follow-up observations of severel years duration the seizures were not repeated and EEG has returned to normal.

Similar movement disorders developed in two 8-year-old retarded children while they were receiving phenytoin. Seizures subsequent to a diphtheria-pertussis-tetanus immunization had developed in each child at 1 to 2 months of age. A static encephalopathy ensued, characterized by mental retardation, ataxia, spasticity, and a mixed seizure disorder. Intermittent dystonia and choreoathetosis developed insidiously while serum phenytoin concentrations were in the therapeutic range. Sustained dystonia and choreoatheosis developed 2 hours after an oral provocation with phenytoin. The baseline abnormalities on the electroencephalogram remained unchanged during the choreoathetosis. Recognizable metabolic abnormalities known to be associated with similar movement disorders were excluded. It was concluded from these studies that the movement disorder is secondary to phenytoin and can occur at therapeutic serum concentrations. Phenytoin is a central anticholinergic agent and a central stimulant of serotonin, and may induce movement disorders as a result of altering these neurotransmitters in the brain. The variable expression of these movement disorders may relate to the nature of the preexisting striatal insult.

Dialysis encephalopathy is a progressive, fatal condition that occurs in patients receiving hemodialysis. It is characterized by abnormalities in speech, myoclonic jerks, and striking changes on the electroencephalogram. We observed dramatic reversal of the clinical symptoms and electroencephalographic abnormalities in four patients with this syndrome who were treated with diazepam. In this paper we propose that in dialysis encephalopathy, some of the symptoms and the electroencephalographic changes represent a form of seizure disorder.

The serotonin precursor L-5-hydroxytryptophan is useful therapy for patients with posthypoxic intention myoclonus. L-5-hydroxytryptophan plus carbidopa was administered to eight patients with this disorder or other syndromes in which myoclonus is prominent. This treatment (1) decreased the frequency of occurrence and amplitude of intention myoclonus in two patients with posthypoxic intention myoclonus and in one with idiopathic myoclonus, (2) had no effect in one patient with congenital encephalopathy and myoclonus, and (3) increased the frequency of occurrence and amplitude of myoclonus in two patients with lipid storage disease, one with myoclonic epilepsy, and in an additional patient with idiopathic myoclonus. Therefore, L-5-hydroxytryptophan does not effect improvement in all forms of myoclonus; it should be given with caution because it produces a high incidence of side effects. A patient's response to L-5-hydroxytryptophan therapy may be important in a diagnostic classification of myoclonic syndromes based on differences in indoleamine neurotransmitter function.
