Seventeen adults with cerebellar stroke confirmed by computerized tomography were reviewed, and divided into two groups: the first group consisted of 10 patients with cerebellar softening, and the second one included 7 cases with cerebellar hemorrhage. The diagnostic rests primarily upon the symptoms and clinical signs. They consist of acute onset of vertigo, headache, nausea or vomiting, ataxia-disequilibrium, then progressing signs of brain stem compression with gaze palsy, cranial nerve palsies and a decreasing level of consciousness. The computerized tomography is the diagnostic test of choice. The interpretation of the scan and of the brain stem and its surrounding cisterns gives decisive help in accessing the indications for surgical treatment.

Thyrotropin-releasing hormone (TRH) has been reported to improve the clinical picture of patients with the predominantly cerebellar form of spinocerebellar degeneration. The authors performed a double-blind, double cross-over, four-month trial, where TRH, at the daily dose of 2 and 4 mg, and placebo were given intramuscularly over a period of one month each. Sixteen patients with Friedreich's disease and 14 patients with different forms of spinocerebellar degeneration completed the trial. Features of cerebellar involvement, such as dysarthria, dysmetria and stance ataxia, showed a slight but significant improvement during TRH treatment. TRH was well tolerated. Transient nausea was the most frequent side-effect.

300 women aged 16-37 received analgesic-sedative preparations for miniabortions preprandially after admittance to the clinic. Anamnesis was followed by routine blood pressure check, then 0.01 mg/kg-1 atropine, 0.1 mg/kg-1 diazepam iv, or 0.05 mg/kg-1 midazolam iv was given to 25 women. 1-2 minutes later 0.5 mg/kg-1 ketamine iv was given, and at the time of insertion of the aspiration cannula into the cervix, another dose of 0.25 mg/kg-1 of ketamine was given iv. The total dose did not exceed 1 mg/kg-1 iv. All patients also received a ketamine-benzodiazepine combination of analgesia prior to the miniabortion procedure. In psychic, unstable women anxiolytic effects were apparent, but in all of them vertigo and the sensation of floating ensued with horizontal and vertical nystagmus, although information could be extracted from them depending on the degree of analgesia. Anterograde amnesia followed, and the systolic and diastolic pressure increased. The maximum duration of analgesic effect was 3-5 minutes, most women became well-oriented without ataxia and returned home 4 hours after the operation. No psychic effects lasted, and nausea or vomiting was minimal. The hallucinogenic effect of ketamine was attributable to the stimulation of the central dopaminergic system, while diazepam (Spofa) influenced the limbic system causing anterograde amnesia. The potential of midazolam-benzodiazepine combination for future sue lies in its very short biological half-life (1.5-2.5 hours) compared with diazepam (24-36 hours).

1. This study presents the results of the preliminary screening of vigabatrin as add-on therapy in an open, non-controlled multicentre study in children with refractory epilepsy. 2. There were 135 children, with an age range of 2 months-12 years. Main seizure type was partial in 42%, generalized in 29%, Lennox-Gastaut syndrome in 19% and West syndrome in 10%. 3. Vigabatrin was added onto current antiepileptic treatment in an initially recommended dose of 40-80 mg kg-1 day-1. However, the doses were frequently increased when tolerance allowed it, and the final mean dose used was 87 mg kg-1 day-1 (27-600). 4. A 75% to 100% reduction in seizure frequency was observed in 25% of patients (11 patients became seizure free) and 50 to 75% decrease in a further 13%. Efficacy was better in partial seizures, with good to excellent results in 49% of patients. The use of high doses, above 100 mg kg-1 day, was not associated with greater efficacy in this preliminary study. 5. No side effects were reported in 79% of patients. Agitation and insomnia were observed in 8.8% and somnolence in 6%. Other adverse events included ataxia (2.2%), nausea (2.2%) and increased appetite (1%). A moderate and transient decrease in haemoglobin was reported in six patients from the same centre; these patients were all receiving very high doses of vigabatrin (250 to 600 mg kg-1 day-1). 6. Vigabatrin thus appears to be a safe antiepileptic drug that may be effective in the treatment of severe epilepsy in children.

Nabilone is a new orally active cannabinoid for the treatment of severe gastrointestinal toxicity associated with cancer chemotherapy. The pharmacological profile of nabilone suggests that it acts primarily by preventing emesis controlled by the medulla oblongata, although its secondary mild anxiolytic activity may contribute to the overall efficacy. Nabilone 2mg twice daily starting 12 hours prior to, and continued for the duration of, chemotherapy produces significant reduction in the severity and duration of nausea and the frequency of vomiting in about 50 to 70% of patients with severe symptoms refractory to conventional therapy. Nabilone has proven to be more effective in controlling symptoms and preferred by more patients than prochlorperazine 10mg 2 to 4 times daily in a limited number of studies, despite a higher incidence of side effects. Comparative trials against other new antiemetic agents, such as high dose metoclopramide, and use of nabilone in combination with other antiemetics remain to be undertaken. The incidence of side effects is high with nabilone; drowsiness, dizziness and/or vertigo occur in 60 to 70% of patients, but rarely lead to drug withdrawal, although more troublesome effects, such as postural hypotension, ataxia, vision disturbance and toxic psychoses, may cause discontinuation of therapy. Thus, nabilone offers an effective alternative to the treatment options available in a difficult therapeutic area - those patients with severe gastrointestinal side effects from cancer chemotherapy who are refractory to conventional therapy.

Forty-two patients with malignant melanoma were treated with doxifluridine, 4000 mg/m2 daily X 5, repeated every 3 weeks. The daily dose was reduced to 3000 mg/m2 in patients who had experienced severe myelosuppression with prior chemotherapy. A total of 35 patients were evaluable for response, and 25 of these received two or more courses. Two responses were observed. Toxicity mainly took the form of nausea, vomiting, stomatitis, dizziness, ataxia, and fatigue. Mild leukopenia was frequent (43%). Nadir counts less than 1.5 X 10(9)/l leukocytes or 50 X 10(9)/l platelets were seen in 7% and 2% of the courses respectively. Doxifluridine has no useful activity against malignant melanoma.

Two incidents of toxin-type food poisoning in N.E. Scotland associated with the consumption of red whelks (Neptunea antiqua) are described. Four patients developed symptoms within 1 h of consuming whole whelks. These included visual disturbances--double vision and difficulty in focusing--tingling of the fingers, prostration and in one subject nausea, vomiting, diarrhoea and ataxia. In all cases recovery was complete in 24 h. Using a newly developed analytical technique the concentration of the causative toxin, tetramine, in the salivary glands of the whelks consumed was estimated at 0.07%, equivalent to a content of 3.75 mg/100 g of the shellfish.

Aneurysm of the vein of Galen is a very rare disease. The authors present a case of secondary aneurysm of the vein of Galen which was confirmed by characteristic clinical symptoms, brain CT and angiographic findings. The patient was a 14-year-old right handed girl with intermittent headache, nausea, vomiting, dysphasia and gait disturbance. Neurologic examination revealed dysarthria, nasal voice, blurring of both margins of optic discs, truncal ataxia and dysdiadochokinesia. Sensory function was normal but right hemiparesis was seen. Roentgenogram of the skull revealed diffuse thinning of the calvarium, widening of sella turcica and erosion of clinoid processes. Computed tomogram of the brain showed dilatation of all ventricles and round hyperdense mass behind the third ventricle in the midline. The lesion was enhanced markedly and homogeneously. Left and right internal carotid angiograms showed arteriovenousmal-formation with drainage to the aneurysm of the vein of Galen.

The rehabilitative course for patients who have suffered vertebral-basilar vascular lesions is often interrupted by intermittent episodes of increasing dizziness, nausea, vomiting, and ataxia. Since CT studies of the brain do not always visualize these lesions reliably, the rehabilitation specialist has been without a diagnostic tool to distinguish between progressive and stable vertebral-basilar system infarctions. Magnetic resonance imaging (MRI) offers a safe, noninvasive, sensitive means of monitoring vascular lesions in the posterior fossa. The purpose of this study was to use MRI to evaluate patients with suspected vertebral-basilar vascular lesions. In three patients studied, MRI was superior to CT scan. Advantages of MRI included lack of artifact due to bone scattering from ionizing radiation, ability to image directly in the sagittal plane, visualization and localization of pathologically smaller lesions, and potential for performing serial studies without exposing patients to large doses of radiation. In each case, MRI data yielded valuable adjunctive information that aided further rehabilitation evaluation and management. We conclude that MRI may be a useful diagnostic and prognostic tool in evaluating and managing rehabilitation patients with vascular lesions involving the vertebral-basilar system.

A 61-year-old woman is presented with a bilateral total ophthalmoplegia as an initial ocular symptom, caused by a midbrain hematoma. She complained of acute headache, nausea, vomiting and bilateral closure of her eyelids. Examination on admission showed meningeal irritation; mild consciousness disturbance; bilateral total ophthalmoplegia; left hemiparesis; ataxia in all extremities, more marked to the left. Computed tomography demonstrated a small hematoma in the midbrain tegmentum. Angiography demonstrated midbrain arteriovenous malformation, and she was treated conservatively. Abduction of both eyes and adduction of the left eye appeared on the next day of the ictus, and after that, improved gradually. Left ptosis had improved since one week after the ictus. Light reflex of the left pupil had seen 5 days after the ictus. At the same time, the left pupil revealed an oval-shape. Right internal ophthalmoplegia continued to exist. One year later, the right eye deviated externally, and the left deviated inferio-medially. Abduction of both eyes was normal. Infraduction of both eyes was seen, but limited on the left. Upgaze paresis remained unchanged, and adduction of the right eye was absent. Adduction of the left eye showed almost full recovery. There was right complete ptosis, but left ptosis became indefinite. These ocular findings indicated typical right oculomotor paresis plus superior rectus paresis of the left eye, which suggested a destructive lesion in the right oculomotor nucleus. Also, her left extremities showed a hemiparesis as a pyramidal tract sign (Weber's syndrome) and an ataxia as a cerebellar sign (Claude's syndrome).(ABSTRACT TRUNCATED AT 250 WORDS)
