A 17 year old high school boy experienced fever and diarrhea, which subsided within 4 days by appropriate medications. Six days later, however, he developed unsteadiness and limb spasm. On the morning of admission, he was found to have drowsiness, dysarthria, gait disturbance and involuntary jerks. When he was brought to the hospital, he was lethargic but could follow simple verbal commands. Frequent involuntary movements manifested by facial grimacings, limb spasms and twitchings with dystonic features were seen. Decorticate posturing was readily elicited by painful stimuli. There was no meningeal irritation sign or gross sensory impairment. The deep tendon reflexes were symmetrically exaggerated with bilateral Babinski signs. Bilateral lateral rectus muscle weakness was found together with mild ptosis and upward gaze limitation. Nystagmus was not present and the funduscopic examination was normal. Immediately he was placed on anticonvulsants, steroid hormone, gamma-globulin and antibiotics as well. A brain CT scan and a CSF examination revealed no abnormality. Meanwhile he continued to show a progressive deterioration associated with fever and status epilepticus, and within 24 hours he lapsed into coma in decorticate posture. An EEG obtained at the 3rd hospital day was compatible with spindle coma. In spite of aggressive treatment he remained febrile and comatous. Therefore, vidarabine (adenine arabinoside) was initiated from the 3rd hospital day for 5 days. Then he began to groan and show frequent choreic movements. For the subsequent 2 weeks he made a slow recovery.(ABSTRACT TRUNCATED AT 250 WORDS)

A 5-year-old girl developed recurrent prolonged episodes of severe oral apraxia, dysarthria, and drooling, similar to the opercular syndrome in children. Each episode lasted several weeks to > 6 months and was associated with exacerbation of epileptiform activity in her EEG. Electrographic status epilepticus during slow wave sleep (ESES) was recorded during three of the exacerbations. The EEG improved markedly when clinical symptoms subsided. Antiepileptic drugs (AEDs) were not effective, although there was some improvement when they were combined with a ketogenic diet. A similar case was described by Roulet et al. We believe that this is a distinct epileptic syndrome, equivalent to the Landau-Kleffner syndrome (LKS).

We report 3 cases of opercular myoclonic status epilepticus (OMASE), characterized by fluctuating cortical dysarthria without true aphasia associated with epileptic myoclonus involving bilaterally the glossopharyngeal musculature. In this syndrome, the inferior rolandic area of either one or the other hemisphere is involved by an epileptogenic lesion of various etiology. Ictally, clonic expression was consistent with epilepsia partialis continua (EPC) and bilaterally and symmetrically involved palatal muscles (cases 1-3), tongue (cases 2 and 3), lips and chin (case 3), and inferior jaw (case 1) due to bilateral projections of the inferior corticonuclear pathways. Postictally, the main clinical sign was pseudobulbar palsy, consistent with Todd's palsy. In our cases, OMASE was either of vascular (cases 1 and 2) or tumoral origin (case 3). In adulthood, early recognition of OMASE, although nonspecific, may be important for early management of carotid occlusive disease because it usually indicates an acute opercular infarction.

The amino acids L-glutamate and L-aspartate have been shown to be excitatory neurotransmitters in mammalian central nervous systems. Antagonists acting selectively at excitatory amino acid receptors have shown antiepileptic properties in several animal models. We report the results of the first therapeutic trial of the competitive NMDA antagonist, D-CPP-ene (SDZ EAA-494), in eight patients with intractable complex partial seizures. All patients withdrew prematurely because of side-effects, including poor concentration (8), sedation (7), ataxia (6), depression (3), dysarthria (2), amnesia (2) and unilateral choreo-athetosis in a patient with contralateral Sturge-Weber syndrome. Seizures were unchanged in four patients and worse in three. A further patient with apparent improvement in seizures in the first week developed complex partial status epilepticus on withdrawal of DCPP-ene. EEG on treatment (5) or in the immediate post-treatment period (2) showed slowing of background activity and, in five cases, an increase in epileptiform activity. Serum concentrations of DCPP-ene were found to be unpredictable and higher than expected from pharmacokinetic data on normal subjects. There was no clear relationship between serum concentrations and the severity of side-effects. Preliminary experience with DCPP-ene in patients with refractory partial seizures is not promising. Evaluation of related compounds is warranted.

A 40-year-old conductor was admitted because of increasing drowsiness and confusion. Two years before admission he had had a first seizure. One year before admission he had a generalized convulsive status epilepticus; the following months he was less able to concentrate. A second status epilepticus was followed by transient weakness of his left arm and a depressed level of consciousness for several weeks. After awakening, he had delusions, and his wife found him demented. In the following months his confusion and drowsiness gradually deteriorated. He had previously had gonorrhoea, an episode of fever and exanthema, and was found to have oligospermia as cause of his infertility. On examination he was disoriented, and he had dysarthria. His left pupil was smaller, but both pupils reacted normally. There was left hemianopia and cerebellar ataxia. CT and MR showed large ventricles and periventricular diffuse lesions in the white matter. CSF examination revealed leucocytosis and increased protein content. Further examination were focussed on serological evidence of syphilis, and finally neurosyphilis was diagnosed. After treatment with penicillin, the patient started to recover.

Foix-Chavany-Marie syndrome (FCMS) is a distinct clinical picture of suprabulbar (pseudobulbar) palsy due to bilateral anterior opercular lesions. Symptoms include anarthria/severe dysarthria and loss of voluntary muscular functions of the face and tongue, and problems with mastication and swallowing with preservation of reflex and autonomic functions. FCMS may be congenital or acquired as well as persistent or intermittent. The aetiology is heterogeneous; vascular events in adulthood, nearly exclusively affecting adults who experience multiple subsequent strokes; CNS infections; bilateral dysgenesis of the perisylvian region; and epileptic disorders. Of the six cases reported here, three children had FCMS as the result of meningoencephalitis, two children had FCMS due to a congenital bilateral perisylvian syndrome, and one child had intermittent FCMS due to an atypical benign partial epilepsy with partial status epilepticus. The congenital dysgenetic type of FCMS and its functional epileptogenic variant share clinical and EEG features suggesting a common pathogenesis. Consequently, an increased vulnerability of the perisylvian region to adverse events in utero is discussed. In honour of Worster-Drought, who described the clinical entity in children 40 years ago, the term Worster-Drought syndrome is proposed for this unique disorder in children.

In patients with focal epilepsy, focal neurological dysfunction can occur due to status epilepticus and also as a post-ictal phenomenon. Bulbar dysfunction as evident by drooling, dysarthria, swallowing difficulties, and palatal-glossalpharyngeal weakness has been reported in conjunction with epilepsy. This is non-progressive and is correlated in its severity with the frequency of seizures. Accompanying EEG discharges are often localized to rolandic areas that cortically represent oral movements and salivation. We report a 6-year-old male and a 6 1/2-year-old female with progressive bulbar dysfunction resulting from epilepsy. Ictal EEGs in patient 1 did not confirm a diagnosis of epilepsy. With no evidence of a cortical or brainstem focus from EEG or MRI, it is very difficult to explain the mechanism of bulbar dysfunction. The complete restoration of bulbar function after treatment with antiepileptic drugs demonstrates the need to consider epilepsy in similar clinical situations.

In September and October, 2004, an outbreak of encephalopathy of unknown etiology occurred in certain areas of Japan including Yamagata, Akita, and Niigata prefectures. These patients had a history of chronic renal failure, most of them had undergone hemodialysis, and also had a history of eating Sugihiratake (Pleurocybella porrigens), an autumn mushroom without known toxicity. Since clinical details of this type of encephalopathy remain unknown, we analyzed the clinical, radiological and electroencephalographic (EEG) features of ten cases of this encephalopathy in Yamagata prefecture. The summary of the present study is as follows: 1. Ten patients had chronic renal failure, and seven underwent hemodialysis. 2. Each patient had a history of eating Sugihiratake within 2-3 weeks of the onset of neurological symptoms. 3. The onset was subacute; the initial symptoms were tremor, dysarthria, and/or weakness of the extremities, which lasted an average of 4.5 days (ranging from 2 to 11 days), followed by severe consciousness disturbance and intractable seizures, resulting in status epilepticus in 5 patients. Myoclonus was also seen in 4 patients and Babinski reflex in 3. 4. Brain CT and MRI examinations were unremarkable in the early stages of the disease. Three to eight days after onset, however, conspicuous lesions appeared in the areas of the insula and basal ganglia in 6 patients. On MRI, these brain lesions were hyperintense on T2-weighted and FLAIR images, and hypointense on T1-weighted images. 5. EEG examination was performed in 6 patients, all of whom showed abnormal EEG findings. Periodic synchronous discharge (PSD) was seen in 2 patients, spike and wave complex in one patient, and non-specific slow waves in 3. 6. Prognosis was different from case to case. Three patients died at 13, 14, and 29 days after onset. Two patients still showed persistent disturbance of consciousness one month after onset. One patient showed parkinsonism after recovering from consciousness disturbance. Four patients recovered nearly completely around one month after onset In 3 of the 4 recovered patients, renal failure was not severe and they did not need to undergo hemodialysis. This suggests that the degree of renal failure is a key for the prognosis of this type of encephalopathy. The present study suggests that this endemic disease is a newly recognized clinical entity of encephalopathy.

We report a 54-year-old man (case 1) and a 79-year-old woman (case 2) who presented with encephalopathy of unknown cause. Both patients were on hemodyalysis and took an autumn mashroom, "sugihiratake" (Pleurocybella porrigens), two to three weeks prior to the onset of neurological alterations. The clinical syndrome of those patients was characterized by weakness and involuntary movements of the extremities (cases 1 and 2) or dysarthria (case 1) at the onset of the disease and subsequent intractable focal motor seizures, resulting in generalized status epilepticus or comatose state, six (case 1) or three (case 2) days after the disease onset. Epileptic seizures were gradually improved in both cases. On brain MRI of case 1, no relevant lesions were detectable at the onset day, but, 6 days after onset, T2-high intensity lesions were noted in the subcortical white matter of the insular cortex, claustrum, external capsule, putamen and globus pallidus on both sides. On brain CT scan of case 2, there were no apparent lesions at the onset day, but, 4 days after onset, low density areas were noted bilaterally in the subcortical white matter of the insular cortex. Electroencephalography of the two patients taken on a day of comatose state showed periodic synchronous discharge (PSD), which disappeared when their consciousness levels were improved. As far as we have examined, there was no findings to suggest the cause of the encephalopathy in routine laboratory examinations and various viral antibody studies of the blood and cerebrospinal fluid. The reported patients could constitute a newly recognized disease entity, "sugihiratake" encephalopathy. Our observations suggest that it can be an encephalopathy with subacute progression and affect mainly the basal ganglia. Neuroimaging study and electroencephalographic findings may help the diagnosis, although they may remain unremarkable for several days after onset of the neurological alterations.

The case of a 63-year-old woman who presented with status epilepticus, coma and hypoventilation is reported. A primary neurological cause was considered. Hypothermia led to further investigations and a diagnosis of severe hypothyroidism. The neurological complications of hyperthyriodism include alteration in mental status with slowness, decreased concentration and lethargy, headache, cranial nerve palsies, dysarthria, hoarseness, myopathy, neuropathy, reflex changes, ataxia, and psychotic episodes. Our patient suffered from a rare consequence of severe hypothyroidism presenting with status epilepticus and she died despite treatment. To our knowledge this is the second patient to be reported with myxoedema coma with this kind of presentation. Despite therapeutic options, there is a high mortality rate.
