Of 488 children with central nervous system neoplasms, 43 (8.8%) had glioblastomas, 22 of which were in the cerebral hemispheres, 16 in the brain stem, two in the cerebellum, and three in the spinal cord. The male to female ratio was 3:2. Glioblastoma multiforme of the cerebral hemispheres occurred at a mean age of 12.7 years, and the frontal lobe was the most commonly involved. Main presenting symptoms included headache (85%), nausea or vomiting (65%), and seizures (35%). Papilledema (45%) was the most common physical finding. The longest survivals were achieved by a combination of operation and radiation (22 months). Brain stem glioblastomas occurred at a mean age of 6.7 years, with the pons as the most frequent site. Nausea or vomiting (50%) and headache (36%) were the main presenting symptoms; the major physical findings were ataxia (43%), cranial nerve palsies (28%), and paresis (28%). The length of survival was greatest with radiation alone (10.5 months). The period of survival of children with glioblastoma multiforme was significantly increased with steroid therapy. Glioblastoma multiforme behaves similarly in children and adults. Intracranial glioblastomas have a more rapidly fatal course than that of other similarly situated gliomas in childhood.

A total of 23 men complained of neurological symptoms after a single severe exposure to toluene di-isocyanate. Effects of exposure were immediate in five men and consisted of euphoria, ataxia, and loss of consciousness. These men and nine others complained of headache, difficulty in concentration, poor memory, and confusion during the next three weeks. Four years later it was found that nine further men had experienced symptoms that they had not been aware of at three weeks. In all, 13 men still complained of poor memory, personality change, irritability, or depression after four years. Psychometric testing showed a selective defect for relatively long-term recall in those with persistent symptoms at four years.

A boy with juvenile onset of symptoms of Alexander's disease had a clinical picture of pseudobulbar palsy, ataxia, and spastic paraparesis. Pathologic examination of the central nervous system revealed the diffuse presence of Rosenthal fibers and patchy demyelination. This may be the first report of a case with significant neuronal changes and inflammation within the brain stem in this disease. The clinical picture of this entity is varied and age-dependent. Alexander's disease may be a motor system specific entity secondary to astrocytic dysfunction.

During an outbreak of abortion caused by equine herpesvirus 1, a neurologic disease characterized clinically by dullness and ataxia occurred in several mares. Equine herpesvirus 1 was isolated from brain and lung of two severely affected mares. Histologically, both mares had disseminated meningoencephalomyelitis characterized by necrotizing arteritis, focal malacia in grey and white matter of brain and spinal cord, and accumulation of lymphocytes and neutrophils in paravertebral ganglia. Eosinophilic intranuclear inclusion bodies occurred in foci of necrosis in thyroid adenomas of both mares.

Neurologic complications may appear before the primary disease, alcoholism, is recognized. The common syndromes are polyneuropathy, the withdrawal syndrome and the combination of Wernicke's encephalopathy and Korsakoff's psychosis. Other conspicuous clinical pictures include ataxia of cerebellar origin, convulsions, acute hallucinosis, myopathy and coma. Rarer disorders are Marchiafava-Bignami disease and central pontine myelinolysis.

Congenital enzymopathic hyperlactacidemia results from a defect of utilisation of pyruvate either at the level of the pyruvate junction (pyruvate-carboxylase, pyruvate-dehydrogenase and Kreb's cycle), or at the level of the unidirectional enzymes on neo-glucogenesis and of neo-glycogenogenesis, e.g. glucose-6-phosphatase, phosphoenol-pyruvate-carboxykinase and glycogen synthetase. The enzymopathies which affect neoglucogenesis associate hyper-lactacidemia and fasting hypoglycemia and more or less marked hepatomegaly. Type I glycogenesis (von Gierke's disease) is the best known example. Enzymopathies which affect the pyruvate junction and the Krebs cycle, may be manifested in addition by: --either chronic neuropathies, e.g. Leigh's disease, recurrent ataxia, and moderate hyperalactacidemia,--or, as in congenital lactic acidoses, which have a rapid and severe prognosis with major hyperlactacidemia. Functional investigation, in particular, loading tests are of great value in orientation and justify the practice of tissue biopsy which permits the enzyme diagnosis. Recent, still unconfirmed knowledge of the pathogenesis of these diseases emphasizes the considerable importance of estimation of blood lactic acid in the investigation of metabolic acidoses of hereditary origin.

A case of pigment variant of Kufs' disease is presented. The nature of the extra-neuronal pigment is discussed. Despite some of the histochemical discrepancies that existed between this pigment and the material that had accumulated in the nerve cells, they seemed to be ultrastructurally related. The hepatocytes contained numerous heterogeneous cytosomes, some of which resembled the storage material of Niemann-Pick's disease. Clinically the syndrome may present with progressive ataxia, spontaneous and reflex, coarse myoclonic jerks and eventual mental deterioration as well as epilepsy and muscle wasting. The pigment variant cannot be distinguished from Kufs' disease except pathologically.

Monkeys were infected intranasally with Herpesvirus suis. After an incubation period of 7 to 13 days the animals became acutely ill and rapidly died. Clinical signs included salivation, incoordination, ataxia and epileptiform convulsions, but not pruritus. Histopathological changes were confined to the central nervous system, and consisted of destruction of neurones with the formation of intranuclear inclusion bodies, gliosis and perivascular cuffing. Virus was isolated from the brain and spinal cord in the later stages of the illness but neutralising antibodies were not detected in serum. The distribution of lesions indicated direct spread of virus from the inoculation site along cranial nerves to the brain.

Institutionalized epileptic patients on long-term anticonvulsant diphenylhydantoin (DPH) therapy were examined clinically. DPH plasma levels were unexpectedly high in 54% despite rather poor seizure control. No patient was free from side effects, which included gingival hypertrophy (90% of patients), increased alkaline phosphatase activity (55%), suggestion of a sensory peripheral neuropathy (34%), central nervous system (CNS) intoxication (22%), coarsened facial features (19%), tendency to bleed excessively (15%), hirsutism (12%), and mild megalocytic anemia (5%). CNS intoxication correlated with high plasma DPH levels, reports of deteriorating behavioral and motor performance, and the findings of nystagmus on vertical gaze or truncal ataxia, though not all patients with high plasma levels were clinically intoxicated. Alarming were the often disfiguring changes of gums and facial structures and the tendency to develop signs of vitamin D deficiency secondary to therapy. Hirsutism was rare in black patients. Plasma DPH level determinations are recommended as part of the management of mentally retarded epileptic patients but do not replace clinical acumen and skill.

A pedigree with a new form of hereditary sensory neuropathy is described. Ataxia and scoliosis rather than loss of pain and ulcerating acropathy are the principal clinical feature. Analysis of the pedigree suggests a dominant mode of transmission with variable age of onset and perhaps reduced penetrance.
