Five patients received overdoses of vincristine ranging from 3.5 to 32 mg. Neurotoxicity accounted for most of the complications observed. Peripheral neuropathies, cranial nerve palsies, paralytic ileus, atony of the bladder, hypertension, hypotension, seizures, inappropriate ADH secretion, and severe bone marrow depression were all encountered. Two patients died within 72 hours of the overdose. Another patient died of sepsis 22 days after the overdose. Two patients recovered and were discharged. The three patients who survived longer than a few days showed improvement in the vincristine-induced neuropathy, and the two long-term survivors had essentially complete recovery. It appears that if a patient can be supported through the critical period following an overdose, he can be expected to recover normal neurologic function.

A symmetrical, bilateral optic neuropathy is reported in 2 patients being treated with ketogenic diets for seizure control. Laboratory tests suggested a thiamine deficiency, and both patients recovered normal visual function after several weeks of treatment with thiamine. The risk of optic nerve dysfunction occurring during the treatment with a ketogenic diet can be minimised if routine vitamin B supplements are given and periodic evaluation of optic nerve function undertaken.

1. Among patients with SLE, 71 (51%) had significant neuropsychiatric problems during the course of the disease. In 52 (37%), the nervous system manifestations were secondary to SLE. 2. The most frequent manifestations were psychiatric dysfunction, seizures, long tract signs, cranial neuropathy, and peripheral neuropathy. 3. Psychiatric abnormalities secondary to SLE were characterized by organic features (present in 22 of 24) and by the association of neurologic lesions which were often diffuse or multifocal. 4. An abnormal cerebrospinal fluid was found in 32% of neuropsychiatric episodes in which specimens were obtained. The most frequently abnormal study was the electroencephalogram (71%), and the least frequent was the brain scan (8%). These studies did not correlate with specific clinical patterns. 5. In 63% of the patients, NP manifestations preceded the diagnosis of SLE or occurred within the first year of diagnosed disease, and in most episodes were associated with evidence of clinical and/or serologic activity of the underlying illness. 6. Only two clinical features showed significant and striking correlations with neuropsychiatric involvement, namely vasculitis and thrombocytopenia. The possible pathogenic implications have been discussed. 7. Only 2 of the 140 patients were felt to have steroid-induced psychoses. In approximately one-half of the NP episodes secondary to SLE, patients were receiving no corticosteriods on presentation. Of those developing while patients were on steroids, the majority occurred on low doses or after tapering from higher levels. 8. The immediate prognosis for improvement in neuropsychiatric function was good with 84% of episodes showing complete or partial resolution. Corticosteroids appeared to be of benefit in a substantial number of patients although their precise role is difficult to quantitate. 9. Five and 10 years survivals for the overall population were 94% and 82%, respectively. There were no significant differences in survival for patients with or without nervous system involvement.

Pharmacological prevention of epilepsy, especially in cases of past cranial trauma, arose as one of the problems connected with this disease. Attention has been called, however, ever more frequently to the neurotoxic effects of antiepileptic drugs symptoms and signs of with brain damage. Drug-induced encephalopathy or neuropathy occur particularly in patients with disorders of anticonvulsant drug metabolism in liver diseases or due to inborn enzymatic defects. Teratogenic and even epileptogenic side effects has been described in cases treated with therapeutic doses of anticonvulsants. The author discusses in this aspect the indications to pharmacological prevention of epilepsy quoting cases observed by her in which cranial trauma was followed by one or several seizures in early post-traumatic period and presence of seizure potentials was found in EEG. During follow-up observations of severel years duration the seizures were not repeated and EEG has returned to normal.

Report on clinical and electrophysiological findings in four members of a family with acute intermittent porphyria in the remission period. One patient had suffered from repeated epileptic seizures of the grand-mal type since the age of 24 years. Generalized and multifocal epileptic potentials were found in her EEG. Two other members of the family, a man and a woman, were found electromyographically and neurographically to have a florid neuropathy with damage to the axon and the myelin sheath. Only the female patient showed manifest clinical signs of the polyneuropathy. The 4th member, who years previously had had abdominal colics and suspect biochemical signs of acute intermettent porphyria, was not striking either neurologically or in electromyographic and neurographic polyneuropathy screening at the time of the examination. Epileptic seizures and the symptoms of the polyneuropathy had a close connection with the menstrual cycle (two cases). Before and at the beginning of the menstruation a deterioration of the disease was observed. Problems of antiepileptic therapy in acute intermittent porphyria are discussed.

Computerized tomography was used to measure cerebral ventricular size in hospitalized alcoholic patients, all of whom had evidence of liver disease. Twelve alcoholic patients with neurologic symptoms such as withdrawal seizures, neuropathy, and drug overdose were included. All these patients had normal results from the mental status examinations by the time of discharge. Alcoholic patients had a much higher mean ventricular size compared to 60 control patients. One third of the alcoholics had markedly enlarged ventricles as opposed to only one of the 60 controls.

We reviewed the clinical and pathological data on 319 neuronal ceroid lipofuscinosis (NCL) cases to determine the degree of variability within the different forms and among and within families. Thirty-six cases (11.3%) were the infantile form; 116 cases (36.3%), late infantile; 163 cases (51.1%), juvenile; and four cases (1.3%), the adult form (Kufs disease). Clinical variability was found in all forms studied, but was most striking in the juvenile and late infantile forms of NCL. The expected initial findings of seizures, dementia, blindness, or motor impairment were evident in 255 cases (80%), and rarer, less typical initial neurological symptoms were seen mainly in the 64 cases (20%) of the juvenile form: behavior abnormalities (18/64), psychoses (12/64), neuropathy (2/64), involuntary movements (15/64), ataxia (9/64). Six juvenile and two adult cases had no detectable impairment of vision. All 319 NCL cases had skin or conjunctive biopsies or buffy coats that showed the characteristic ultrastructural abnormalities of NCL. Variability was evident in 16.7% in that a combination of fingerprint, curvilinear, and membranous profile inclusion bodies was observed in storage lysosomes, although one type of inclusion was distinctly predominant for each form. Postmortem examination of brains of 19 NCL cases (three with the infantile form, six with the late infantile form, nine with the juvenile form, and one with the adult form) revealed characteristic changes. Sixteen of the 19 NCL brains (84%) showed pathological variability in that they contained more than one kind of characteristic inclusion body in the neuronal lysosomal storage compartment. In all 19 NCL brains, small amounts of aging lipofuscin were also found.(ABSTRACT TRUNCATED AT 250 WORDS)

A retrospective study of the neurological problems arising in HIV-I seropositive patients in a single defined geographical area was undertaken. Ninety patients were referred for a neurological opinion from a total known HIV-I seropositive population of 436. Minor problems were frequently encountered early in the course of disease (20 at CDC stage II, 12 at CDC stage III), including seizures related to drug abuse in six. The most frequent neurological problem in those patients in CDC group IV (58 patients) were the AIDS dementia complex (14 patients), an axonal sensorimotor neuropathy (12), toxoplasmosis (nine) and cryptococcal meningitis (three). All patients with a structural lesion had appropriate focal signs on examination. The value and role of CT cranial scanning in the diagnosis of toxoplasmosis is discussed and the importance of recognizing potentially treatable causes of both intellectual impairment and cytomegalovirus-related neuropathies is stressed. This is the first report of an unselected series of patients at all stages of HIV-I related neurological disease from a single UK centre.

We reported 9 cases of primary Sjogren syndrome (SS) who were complicated with nervous system involvement. All were women. Age between 24 to 58 years old. Their clinical symptoms of the nervous system varied widely, 7 of them manifested with the involvement of central nervous system, the main features were in case 1 bouts of seizures, case 2 multi-level damage of the brain and spinal cord which was similar to multiple sclerosis, case 3 recurrent hemiplegia caused by cerebral thrombosis then fatal vascular hemorrhage, case 4 sudden hemiplegia, case 5 persistent psychological disturbance, case 6 cranial neuropathy of V and VII, case 9 multi-focal symptoms of ataxia, myelopathy and transient blindness. 5 of the 9, case 3, 6-9 all appeared with the symptoms of peripheral neuropathy, case 7 also complicated with carpal tunnel syndrome. 4 of the 9 cases also complicated with renal tubular acidosis and/or chronic active hepatitis and/or fibrosing alveolitis and/or thrombocytopenic purpura and/or myositis. No differences of the positivity of autoantibodies was observed between those with or without nervous system involvement.

In recent years there are a considerable increase in alcohol consumption in Taiwan, which may have been accompanied by increased incidence of alcohol-related physical disease. This study was designed for an understanding of neurological problems in chronic alcoholic patients. One hundred and five cases of chronic alcoholics with neurological problems were collected. All had taken more than 100 g alcohol daily for more than 8 years. They were all males, with a mean age of 47.0 +/- 1.3 years, mean daily alcohol consumption of 185.1 +/- 9.0 g (mean +/- S.E.). These chronic alcoholic patients showed various neurological problems. Patients showing typical clinical features of alcoholic neurological disease are now rather rare. Most of the patients had manifestations of more than one problems: polyneuropathy (74.3%), alcoholic tremor (37.1%), hallucinosis (30.5%), myopathy (26.7%), head injury (24.8%), withdrawal seizures (18.1%), Wernicke encephalopathy (15.2%), paranoia (13.3%), and stroke (15.2%). Furthermore, we divided all the patients into 5 categories, they were: encephalopathy, 59 cases (56.2%); stroke, 16 cases (15.2%); cerebellar degeneration, 12 cases (11.4%); neuropathy, 78 case (74.3%); and myopathy, 28 cases (16.7%). The daily alcohol consumption and duration of daily drinking were different significantly (p less than 0.05) among five different syndrome categories.
