In nine of 62 children with benign occipital epilepsy (BOE) the onset was stormy and alarming. The first and often only seizure was characterised by prolonged loss of consciousness lasting up to 12 hours, suggesting an acute cerebral insult. In all but one case there was a tonic aversion either of eyes alone or of both head and eyes which was interpreted as conjugate deviation. The other accompanying ictal motor phenomena were either partial or generalised convulsions. In five patients the seizure was heralded by a headache, and in five cases was accompanied by vomiting. The seizure began with visual symptoms in only one patient. The seizure occurred while awake in seven and during sleep in two. The age at onset was from 3 1/4 to 10 years. Interictal EEGs showed occipital discharges typical of BOE, and the clinical course was benign. In four cases a few partial or complex partial seizures recurred during subsequent anticonvulsant therapy, but in five cases seizures never recurred. Anticonvulsants were discontinued in five patients who remained free from seizures for one to 11 1/2 years after withdrawal of treatment. Sudden coma in a child associated with focal features such as tonic deviation of the head or eyes or both may represent a benign seizure disorder.

A 17 year-old girl was suffering complex partial seizures, secondary generalized epilepsy and seizures manifested only by vomiting. The neurological, laboratory, radiological studies and the brain CT were normal. The EEG recording of an ictal vomiting showed bisynchronous spike-and-wave and sharp slow-wave discharges. An interictal paroxysmal focus of the right temporo-occipital region appeared at the EEG and a marked photoconvulsant effect was induced by light stimulation. The patient remained seizure-free for the last 4 years on carbamazepine therapy. The authors suggest the vomiting fits originate from the epileptic discharges on the Ammon's horn. The depths of the temporal lobe appear clearly involved in this type of seizures and the rolandic and pre-rolandic neighboring areas are attended too.

A retrospective method was used to estimate the incidence of recurring motion-sickness, cyclic vomiting and abdominal pain considered as different manifestations of a so-called periodic syndrome in 100 migraine sufferers, 100 epileptics and 100 control subjects in the pediatric age group. Such recurrent symptoms are significantly more frequent in those suffering from migraine than in the other two groups. Examination of subgroups of patients affected by particular forms of migraine (classical and common) and of epilepsy (generalized seizures, simple partial seizures, complex partial seizures) contributed little new to our understanding of the nature of periodic syndrome. It is concluded that the above symptoms of periodic syndrome should generally be considered as manifestations of a migrainous rather than of an epileptic disorder.

We describe the development of temporal lobe epilepsy in an 84-year-old man who had suffered domoic acid intoxication. Following intoxication he had nausea, vomiting, confusion, and coma. Generalized convulsions and complex partial status epilepticus progressively developed. After 3 weeks he improved and was seizure free with severe residual memory deficit. Electroencephalograms initially showed periodic epileptiform discharges, later evolving to epileptic abnormalities over frontotemporal regions with diffuse slow waves. Eight months after the intoxication the electroencephalogram was normal. One year after the acute episode, complex partial seizures developed. Electroencephalograms showed epileptic discharges independently over both temporal lobes, with left-sided predominance. Magnetic resonance imaging revealed a hyperintense T2-weighted signal and atrophy of both hippocampi; a positron emission tomographic scan showed bitemporal decreased glucose metabolism. Pneumonia developed and the patient died 3 1/4 years after the intoxication. Autopsy disclosed severe bilateral hippocampal sclerosis. The seizures following acute domoic acid intoxication, the postmortem pathology, and the fact that temporal lobe epilepsy developed 1 year after intoxication indicate that the human hippocampus is also vulnerable to kainate receptor excitotoxicity, and provide strong evidence supporting the role of excitotoxic injury in epileptogenesis. This report provides a unique human parallel to, and validates the animal model of, kainate-induced epilepsy as an important tool for studying temporal lobe epilepsy.

This is the first randomized, double-blind, parallel-group, multicenter trial that evaluated the efficacy of divalproex sodium monotherapy by comparing seizure frequency in 143 patients with poorly controlled partial epilepsy randomly assigned to high (80 to 150 micrograms/mL; 555 to 1,040 mumol/L) or low (25 to 50 micrograms/mL; 175 to 345 mumol/L) plasma valproate groups. There was a statistically significant reduction from baseline in the 8-week frequency of complex partial (p = 0.001) and secondarily generalized tonic-clonic seizures (p = 0.018) for patients in the high, compared with the low, plasma valproate group. Compared with baseline, there was a 30% median reduction in complex partial seizures for patients in the high group and a 19% increase for those in the low group. The median reduction for secondarily generalized tonic-clonic seizures was 70% for patients in the high group compared with a 22% increase in the low group. Adverse events that occurred significantly more frequently in the high group included tremors, thrombocytopenia, alopecia, asthenia, diarrhea, vomiting, and anorexia. This study demonstrates the efficacy of divalproex sodium as monotherapy for the treatment of partial-onset seizures and supports its role as one of the first-line antiepileptic drug treatments for patients with partial epilepsy.

Childhood epilepsy with occipital paroxysms (CEOP) is an idiopathic localization-related epilepsy. A typical seizure in CEOP begins with visual symptoms, followed by hemiclonic seizures, complex partial seizures or generalized tonic-clonic seizures. Benign nocturnal childhood occipital epilepsy (BNCOE), characterized by nocturnal seizures with tonic deviation of the eyes followed by vomiting, has the same electroencephalographic features as CEOP. In this study, we report the seizure symptoms and electroencephalographic features of 21 cases with CEOP or BNCOE. Out of these patients, nine had BNCOE, six had CEOP, four had CEOP and BNCOE and the remaining two belonged to the incomplete syndrome because of no paroxysmal discharges in EEG. When the patients with BNCOE awoke from sleep, they had tonic deviation of the eyes and could describe visual symptoms. Patients with CEOP had seizures beginning with visual symptoms followed by loss of consciousness but no generalized convulsions. In three cases, in addition to the occipital spikes, independent centro-temporal spikes were recorded and in another three cases generalized spike-wave discharges were recorded. Such a combination suggests the idiopathic nature of these epilepsies. We concluded that in the diagnosis of CEOP and BNCOE, the seizure symptomatology is important even if the EEG can be considered normal.

Ornithine transcarbamylase deficiency is an X linked disorder and the most common inherited cause of hyperammonaemia. Fluctuating concentrations of ammonia, glutamine, and other excitotoxic amino acids result in a chronic or episodically recurring encephalopathy. A heterozygous female patient first presented with protein intolerance, attacks of vomiting, and signs of mental retardation in early childhood. At the age of 16 complex partial seizures occurred which were treated with sodium valproate. Seven days after initiation of valproate therapy, she developed severe hyperammonaemic encephalopathy with deep somnolence. The maximum concentration of ammonia was 480 micromol/l. After withdrawal of valproate, three cycles of plasma dialysis, and initiation of a specific therapy for the inborn metabolic disease, ammonia concentrations fell to normal values. The patient remitted, returning to her premorbid state. Valproate can cause high concentrations of ammonia in serum in patients with normal urea cycle enzymes and may worsen a pre-existing hyperammonaemia caused by an enzymatic defect of the urea cycle. Sufficient diagnostic tests for the detection of metabolic disorders must be performed before prescribing valproate for patients with a history of encephalopathy.

We report a 6-year-old girl with Japanese B encephalitis. The initial symptoms were high fever, headache and vomiting. On the second day of illness, she developed hemiconvulsion and was admitted to our hospital. Physical examination demonstrated a stiff neck. C-reactive protein elevated to 22.7 mg/dl. CSF examination showed a marked increase in the cell count (10,896/3 mm3). During the course of the treatment, she showed transient hemiparesis and dysphagia, followed by akinetic mutism lasting for about a month. The patient was left with severe cognitive and memory impairment and complex partial seizures but no motor dysfunction. Japanese B encephalitis was diagnosed by means of serological examination. Magnetic resonance imaging revealed cystic lesions in the medial and posterior thalamus and substantia nigra and severe atrophy of the hippocampus. Despite the involvement of substantia nigra, the patient had no parkinsonism. The cognitive impairment may in part be explained by the lesions in the medical and posterior thalamus.

We report 3 cases presenting ictal vomiting during partial seizures of temporal lobe origin. Two patients had complex partial seizures accompanying vomiting characteristics. Ictal vomiting occurred early in the course of the seizure when rhythmic discharges involved predominantly the left hemisphere, the language dominance hemisphere. The other patient had ictal vomiting in simple partial seizures which originated from the right temporal lobe or the language nondominant side. All 3 patients underwent anterior temporal lobectomy with promising outcomes. Pathologic diagnosis included hippocampal sclerosis in 2 patients and astrocytoma in 1 patient. In our patients, ictal vomiting does not lateralize temporal lobe epilepsy and is not specific to pathology.

The natural history, management, and long-term outcome for patients with benign, intrinsic tectal plate gliomas remain controversial in spite of their propensity to cause late-onset hydrocephalus. A 10-year retrospective review has identified 11 consecutive children with tectal plate lesions. Headache, vomiting, a decline in school performance, tremor, and complex partial seizures were common presenting symptoms. All patients presented with signs and symptoms of hydrocephalus. Magnetic resonance (MR) imaging delineated an intra-axial mass lesion of the midbrain primarily localized to the tectal plate which uniformly was hyperintense on T2-weighted imaging and had a more variable appearance on T1-weighted imaging and rare enhancement with gadolinium. No patient underwent surgical resection, chemotherapy, or radiotherapy. Three of 11 patients (27%) showed evidence of progression in size or a new focus of enhancement on MR imaging, which was clinically asymptomatic. In this series, no patient with a tectal plate lesion less than 1.5 cm in maximal diameter and without gadolinium enhancement showed any evidence of clinical or radiological progression. Although intrinsic tectal lesions in children are clinically indolent and the initial management consists of CSF diversion, these lesions may eventually progress and still warrant long-term follow-up with serial MR imaging.
