Among 25 baboons, Papio papio, 2 consistently showed acute dystonic reactions, with mouthing, compulsive gnawing and limb and trunk dystonia, following the intravenous administration of neuroleptics and related drugs (haloperidol, 0-6-1-2 mg/kg; pimozide 0-5-2-5 mg/kg; chlorpromazine 5-25 mg/kg; metoclopramide 1-5-1-7 mg/kg; oxyperomide 0-25-1-0 mg/kg). The syndrome was not seen after thioridazine (3-7 mg/kg). The dystonic responses occurred within 1-2 h of drug injection and lasted for 2-24 h. They were abolished for 1-3 h within 1-2 min of the intravenous injection of acetylcholine antagonists (benztropine 0-2 mg/kg; hyoscine 0-02 mg/kg). Pre-treatment with a combination of reserpine (2 mg/kg) and alpha-methylparatyrosine (2 X 200 mg/kg) substantially reduced the dystonic response to haloperidol. A second larger dose of haloperidol (5 mg/kg), given 60-90 min after 0-5 mg/kg) initially reduced the intensity of the dystonic response, but after 29 min induced vomiting and generalized seizures in the idiosyncratic baboons. The hypothesis is advanced that the dystonic responses result from release of dopamine on to a sub-population of receptors in the striatum that are relatively insensitive to blockade by neuroleptics.

A 4-year-old girl who developed convulsions after an accidental ingestion of excessive dosage (50 mg/kg) of nalidixic acid, while treated with the drug (50 mg/kg/day) over 30 days for a urinary tract infection, was reported. Thirty minutes after ingestion, vomiting, tonic-clonic seizures, and abnormal movements were supervened. After ninety minutes, the serum levels of nalidixic acid and hydroxynalidixic acid were 146.1 and 48.9 microgram/ml, respectively. In controls, the mean levels of nalidixic acid and hydroxynalidixic acid were 7.8 +/- 6.8 (SD) and 3.02 +/- 2.6 microgram/ml, respectively.

The clinical and pathologic findings in 20 patients with hypertensive encephalopathy were reviewed. The dominant central nervous system (CNS) symptoms were altered state of consciousness and severe headache. Nausea, vomiting, and visual disturbances were less common. Seizures and focal signs were infrequent. The changes seen were invariably accompanied both by the characteristic ophthalmoscopic alterations of malignant hypertension and by uremia. The neuropathologic changes consisted of severe vascular alterations (fibrinoid necrosis of arterioles, thrombosis of arterioles and capillaries), and of parenchymal lesions (microinfarcts, petechial hemorrhages) secondary to the vascular lesions. The vascular changes were not confined to the brain but were diffuse, affecting the eyes, kidneys, and other organs. In the CNS the brainstem was most severely affected. Cerebral edema was not observed, even in those patients who had increased cerebrospinal fluid pressure and papilledema.

We retrospectively reviewed the manifestations of influenza A2 in 83 hospitalized young children. Our purpose was to define the spectrum of clinical illness in this age group. Findings included fever (91%), vomiting or diarrhea (49%), pharyngitis (34%), pneumonitis (29%), otitis media (24%), conjunctivitis (13%), croup (13%), and bronchiolitis (6%). Neuromuscular manifestations occurred in 16 patients (19%) and included seizures, apnea, opisthotonos, and myositis. Three children had cerebrospinal fluid pleocytosis. Children younger than 3 months of age had fever less often and gastrointestinal symptoms more often than older children. Threee children died of progressive pneumonitis. We conclude that influenza A2 may cause a wide range of respiratory and neurologic findings in infancy and early childhood.

In a 11-year-old girl with urinary tract infection symptoms and signs of Henoch-Schoenlein syndrome developed with neurological complications in the form of headaches, vomiting slightly marked signs of pyramidal tract and cerebellar damage and severe psychomotor temporal-lobe seizures. These very violent neurological manifestations disappeared completely after control of infection. The authors point out that prognosis in Henoch-Schoenlein syndrome even with such severe neurological complications is good.

A unique association of Sturge-Weber syndrome and atlanto-occipital assimilation is presented. A 18-year-old male was admitted in emergency because of the sudden severe headache and vomiting. He had vascular nevus in the right half of the face at birth and several episodes of generalized convulsive seizures. On admission craniogram demonstrated calcification in the right occipital area. Neurological examination revealed tenderness in the nuchal region, moderate limitation of cervical mobility in a antero-posterior direction, Bruns-Cushing type nystagmus, bilaterally diminished gag reflex, and positive Romberg's test. Spinal tap showed crystal clear CSF with normal pressure. EEG showed paroxysmal slowing focus in the right parieto-occipital area. Polytomography of the craniovertebral junction demonstrated the unilateral atlanto-occipital assimilation on the left associated with the aplasia of the right posterior arch. Myelography was negative. A right carotid angiography disclosed the dilatation of the basal vein of Rosenthal and abnormal venous vasculature. CT-scan demonstrated the calcified region of the right occipital area more distinctly than the plain roentogenogram, but the enhancement study of the leptomeningeal angioma of the Sturge-Weber syndrome was negative. Never been found this rare association in a review of the literature, the authors discussed the clinical and radiological findings of both diseases.

The clinical picture of Reye's syndrome, characterized by an acute severe disease of brain and liver, initially has nonspecific generalized symptoms with cough, myalgia, and fever. The prognosis is poor. The disease starts with an infection, quickly followed by vomiting and loss of consciousness. In this phase the serum bilirubin is moderately raised, the transaminases markedly so. In addition to gastro-intestinal bleeding there may be hypoventilation, hypoglycaemia and seizures. Morbid anatomically there is a small-drop fatty infiltration of the liver and other organs with cerebral oedema. Aetiology and pathogenesis remain uncertain. Numerous therapeutic measures have been proposed.

Fifteen epileptic patients with mild seizures of the narcolepsy type were treated with a combination of succinimide (average dose 750 mg) and dipropylacetate (average dose 1,200 mg), medication with each drug alone having brought no success. The combination of drugs stopped the seizures in eleven patients, in three they almost stopped and in one the frequency of seizures was halved. An E.E.G. was recorded in twelve, with improvement in each. Side effects occurred in five patients (nausea, vomiting, singultus and fatigue), but the drug had to be discontinued in only one instance.

In 12 rhesus monkeys the injection of alumina cream into the temporal cortex, amygdala or hippocampus induced seizures after a latent period of six weeks to three months. Clinically the attacks are characterized by an arrest of movement, staring, unresponsiveness to most stimuli, wandering conjugate eye movements, automatisms, twitching of the contraleteral ear and less commonly commonly vocalization, chewing, hiccoughing, vomiting, adversive head movements and twitching of the face. The spiking from the amygdala and hippocampus, which usually fire together, propagates to the temporal cortex and multiple subcortical structures including the hypothalamus, anterior perforated space, anteromedial thalamus, cingulate gyrus, putamen, globus pallidus, subthalamus and mesencephalic reticular formation; from the temporal cortex to the amygdala and hippocampus, and secondarily to the diencephalic centers. There is a fairly consistent sequence of preferential propagation. Although there are some differences in the occurrences of clinical manifestations depending upon the sites of the focus, no specific structural correlation with clinical manifestations could be established. This experimental condition may provide a proper model for the study of clinical psychomotor epilipsy.

37 cases of cerebral hemispheric tumours are presented. These make up 23,1% of all the intracranial tumours observed over a period of 11 years in a Child Neurology Service. 19 cases were males and 18 females. Their ages were between 16 days and 7 1/2 years. Vomiting and headache were usually the first symptoms followed by seizures, frequently of the focal kind. Motor difficulties used to appear later. 69.6% of the cases presented a malfunctioning focus on the E.E.G. on the side of the tumor. The simple cranial X-Rays showed firstly widening of the fronto-parietal sutures, intracranial calcifications were seen in some of the cases with ependymonas and piloid astrocytoma in patients with Bourneville's disease. Pneumoencephalography as well as carotid angiography, radioisotope examination and computerized tomography gave us very positive results in the localization and determination of the size of the tumor. The ependymomas showed pathological vascularization regularly. The nature of the tumours corresponded to: 14 cases of ependymoma, 8 cases of astrocytoma I and II types, 1 case of astrocytoma of types III and IV, 3 cases of plexus papilloma, 2 cases of meningioma, 1 case of sarcoma of the basal ganglia, 1 case of teratoma, 3 cases of indifferentiated malignant tumours, 4 cases not proven. There was a 20% survival of patients five years later.
