A case of hypertensive intracerebellar hematoma surgically treated and cured was reported. The 41-year-old male had two cerebrovascular attacks with headache and vomiting followed by left hemiparesis. Drowsiness and dysarthria appeared the next day. The patient was admitted to a hospital, where right facial palsy, loss of right gag reflex and paralytic hemiplegia on the left side were noted. On the 7th day, the patient's consciousness became clear byt the other neurological evidences did not change. On the 14th day, bradycardia and central hyperventilation appeared and he became drowsy again. The patient was transferred to the authors' clinic. When the patient was admitted, he showed typical cerebellar signs such as nystagmus, ataxia, and slurring speech with pyramidal sign on left side and cranial nerves paralysis on right side, and also showed the changes of vital signs as a medullary syndrome in the late stage of the course. The vertebral angiogram revealed a space taking process in the right cerebellar hemisphere. The old blood (30g) was removed by suboccipital craniectomy. The hematoma cavity had a communication with the IVth ventricle through a small perforation in the medial wall of the hematoma. Spontaneour intracerebellar hematoma including of hypertensive origin is not rare in the reports of autopsy but surgically treated case has only rarely been reported. The main reason of few survivals should be in its fulminate course.

Clonazepam or 5-(2-chlorphenyl)-1, 3-dihydro-7-nitro-2H-1,4benzodiazepin-2-one, is a close structural and pharmacological relative of nitrazepam. It has a broad spectrum of activity against the various types of epilepsy, and is effective in many patients whose condition has proved resistant to other antiepileptic drugs. Its chief uses are in status epilepticus, in which intravenous clonazepam may replace diazepam as the drug of first choice, and in the minor motor seizures of childhood, particularly petit mal absences, the Lennox-Gastaut syndrome and infantile spasms. Clonazepam is also at least as effective as current treatment in psychomotor and myoclonic epilepsies, but seems unlikely to replace phenytoin and the barbiturates in the treatment of grand mal or focal motor seizures except in patients resistant to standard therapy. Initial success with clonazepam can be followed by loss of effect, but benefit can often be restored, at least initially, by temporary interruption and re-institution of treatment. Side-effects are common with clonazepam. Most patients experience drowsiness and fatigue, which are frequent causes of withdrawal, together with lesser incidences of ataxia, dystonia, hypotonia, and hyperactivity. These effects usually disappear with continued therapy, and are minimised by gradual introduction of the drug over 2-4 weeks. Hypersalivation and excessive bronchial secretion may be a problem in children and infants.

Anticholinergic agents may lead to a syndrome described by Longo as the Central Anticholinergic Syndrome (CAS). Patients with this syndrome exhibit one or more of the following: though impairement, disturbance of recent memory, hallucinations, ataxia, excitement, drowsiness of coma. We have reviewed our use of anticholinergics and tried to correlate it with the occurrence of the above symptomatology and have treated 200 cases in which the CAS was diagnosed with physostigmine salicylate (0.04 mg/kg). We also successfully treated 2 cases of apparently central anticholinergic hyperpyrexia in the same way. We would suggest that physostigmine be included in the armamentarium of every anesthetist to combat anticholinergic poisoning by the wide range of presently used anticholinergic drugs. (Act anaesth. belg., 1976, 27, 45-60).

Clonazepam, an antiepileptic benzodiazepine derivative was administered into 30 patients mainly with incurable type epilepsy. Results were as summarized below: (1) Clonazepam was effective in 44.4% of 36 cases of seizures. The initial effect was noticed in 55.6%. (2) Clonazepam was proved to have a broad spectrum in its efficacy. It showed the highest rate of effectiveness, 71.4%, on psychomotor seizures. (3) Clonazepam was effective in all 4 cases of the photogenic epilepsy which shows the photosensitivity in the EEG. With the exception of 1 case, the sensitivity in the EEG also disappeared responding to clonazepam. (4) The Jacksonian type of the partial motor seizure disappeared in 2 cases after the administration with clonazepam. (5) The effects of clonazepam of EEG were examined in 24 patients. The abnormality of the basic activity, the diffuse epileptic discharge and the focal epileptic discharge were improved in 29.2%, 61.5% and 66.7%, respectively. In addition, the rate of the clinical effectiveness was high in the cases with the centrencephalic discharge. (6) Side effects were observed to have appeared in 38.9% of the patients. They were mostly drowsiness and ataxia. (7) Based on the above-mentioned results, it can be claimed that clonazepam is effective on psychomotor seizures, photogenic epilepsy and the secondary type of generalized convulsion (Jacksonian).

Clonazepam, a chlorinated derivative of nitrazepam, was administered to 10 children with absence seizures. Serum concentrations were measured after 8 weeks of treatment, at steady state. Seizure frequency reports and the 12-hour telemetered electroencephalogram were studied before and after 8 weeks of treatment to determine the frequency and duration of generalized spike-wave paroxysms. The clonazepam dosage ranged from 0.028 to 0.111 mg per kilogram and was reflected in serum levels ranging from 13 to 72 ng per milliliter, with an excellent correlation between dose and serum level. Eight of the 10 patients showed a significant decrease in seizure frequency, with three experiencing no seizures at all. Six patients had side effects, predominantly drowsiness and ataxia. This preliminary study shows clonazepam to be useful in the treatment of absence seizures in children and to merit further study.

In a double-blind crossover trial sodium valproate or placebo was added to the existing anticonvulsant treatment of 20 patients with chronic uncontrolled epilepsy. Sodium valproate 1200 mg/day significantly reduced the frequency of both tonic-clonic and minor seizures in these patients. Only mild and transient side effects occurred (drowsiness, ataxia, and nausea), and these may have been due to the effect of adding sodium valproate to existing phenobarbitone or phenytoin treatment. Further controlled trials are needed to assess more fully the efficacy of this drug in various types of epilepsy.

A 48-year-old man, who took by mistake a sip of ointment containing dichloroethane, survived, and showed a course of two phases of toxic symptoms. After an initial narcosis and an interval with few pathological symptoms seizures, myoclonia and somnolence occurred. Irreversible final disturbances were lasting mental defects, cerebellar dysarthria, ataxia, and hydrocephalus. Concomitant diseases were acute liver dystrophy, nephropathy, and anemia. The clinical picture of dichoroethane posoning is outlines, the pathogenesis of this particular cerebral lesion described, and the therapy discussed.

In nine cases of phencyclidine hydrochloride poisoning, early signs of overdose included drowsiness, nystagmus, miotic pupils, blood pressure elevation, increased deep tendon reflexes, ataxia, anxiety, and agitation. In more severe cases, seizures, spasticity, and opisthotonos were seen in addition to deep coma and respiratory depression. Treatment included removal by emetics or lavage, hydration, and a quiet, reassuring environment. Spasticity, agitation, and ocular manifestions responded to diazepam. Psychiatric intervention was instituted after the patients were stable and no longer agitated.

Three cases (case 1, female, aged 30; case 2, male, aged 32; case 3, male, aged 34) of benign brainstem encephalopathy with truncal ataxia were reported. Two patients had prodromal symptoms Neurological examination revealed truncal ataxia in all cases. As additional neurological signs, anisocoria, mydriasis, nystagmus, ptosis, transient opsoclonus, and facial palsy were seen. There was neither drowsiness nor myoclonus in the three cases. On laboratory examinations, cold agglutination test revealed significant elevation in two cases. The examination of cerebrospinal fluid showed a moderate rise of proteins in one case, but did not revealed pleocytosis in any of the cases. Magnetic resonance imaging of one patient revealed an area of high intensity in the left pontine tegmentum by T2-weighed imaging. The prognosis for all these cases was good, and the reappearance of neurological signs was not present until now. Our cases were different from brainstem encephalitis (Bickerstaff's encephalitis) because of an absence of disturbed consciousness and no pleocytosis in the cerebrospinal fluid. Our cases were also different from "myoclonus-opsoclonus syndrome" because of an absence of myoclonus. We discussed a possibility of a new clinical syndrome which we call "benign brainstem encephalopathy with truncal ataxia".

Even though acute poisonings with benzodiazepines are extremely common, less is known of the clinical toxicity of recent derivatives, particularly in children. 1,989 cases involving ethyle loflazepate, flunitrazepam, prazepam or triazolam recorded at the Lyons Poison Center and due to 1 compound and associated with clinical symptoms were selected for study. Children less than 16-y of age accounted for 482 cases. Sleepiness, agitation and ataxia were significantly more frequent in the children. Hypotonia was seldom observed but was indicative of severe poisoning. The dangerous toxic dose of these compounds in children is suggested to be 0.78-0.90 mg ethyle loflazepate/kg, 0.26-0.29 mg flunitrazepam/kg, 7.80-9.00 mg prazepam/kg and 0.06-0.07 mg triazolam/kg. These results are in keeping with the relatively low acute toxicity of the older benzodiazepines.
