We evaluated blood concentrations and clinical findings in 17 cases of isopropanol (IPROH) ingestion seen over a 8.5 year period at our institution. Eight ingestions involved IPROH alone ("pure") while the remainder involved at least ethanol in addition to IPROH ("mixed"). Fourteen patients had a history of alcoholism. Admission blood IPROH concentrations ranged from 5 to 70 mg/dL while the concentration of the acetone metabolite ranged from nondetectable to 220 mg/dL. The mean acetone concentration was significantly higher for "pure" ingestions than for "mixed" ingestions (p less than 0.05); however, the mean IPROH concentrations showed no significant difference. The mean anion gap was significantly higher for "mixed" ingestions than for "pure" ones (p less than 0.01). Fifteen patients were either alert or lethargic while two, who had ingested no compounds other than IPROH, were comatose. The most common other physical findings were tachycardia (10 cases), decreased deep tendon reflexes (5), dysarthria (4), and ataxia, hypotension, fever, and mydriasis (3 cases each). None of the findings including level of consciousness showed statistically significant correlation with the IPROH concentrations. Twelve patients were hospitalized; eleven of these recovered with supportive care alone. One patient expired from trauma suffered in a motor vehicle accident.

We studied 55 cases of cerebellar atrophy identified by computerized tomography. Atrophy was determined by subjective assessment and objective measurements (superior cerebellar cistern, fourth ventricle, and brainstem). Different patterns of cerebellar atrophy were related to clinical diagnoses. A high incidence of vermal atrophy was observed in primary cerebellar degeneration and chronic alcoholism. More than half the patients with alcoholism had hemispheral atrophy. Vermal atrophy and enlargement of superior cerebellar cisterns (but not hemispheral atrophy) were associated with carcinomatous cerebellar degeneration. Atrophy caused by chronic phenytoin usage showed a specific pattern of enlargement of the cisterna magna, cerebellopontine angle, and superior cerebellar cisterns. Supratentorial atrophy was increased significantly only in the alcoholics. In general, limb ataxia, dysarthria, and nystagmus were related to hemispheral but not to vermal atrophy.

Levofloxacin-induced-neurological adverse events such as convulsion, involuntary movement (tremor, myoclonus and chorea-like) and visual hallucination in two elderly patients are reported. A 67-year-old man with minor alcoholism and a past-history of gastrectomy and cholecystectomy was given 300 mg/day of oral levofloxacin and fulfenamic acid for an upper respiratory infection. On the 4th day, he reported gradual exacerbation of hand tremor which resembled chorea-like involuntary movement and gait disturbance. He also experienced visual hallucinations. On the 7th day, he suffered generalized convulsions and was admitted. Serum concentration of levofloxacin at this time (3 hours after last administration of a 100 mg tablet of levofloxacin) was 3.6 micrograms/ml. Cessation of the agents promoted complete recovery of these neurological adverse effects within a week. Another 85-year-old man with chronic bronchitis and slight renal impairment received long term administration of 200 mg/day of levofloxacin. On the 68th day of administration, gradual exacerbation of gait disturbance, dysarthria and chorea-like involuntary movement occurred. On the day of admission, 76 days after the start of administration, the serum level of levofloxacin was 2.55 micrograms/ml and that of spinal fluid was 1.12 micrograms/ml (3 hours after the last administration of a 100 mg tablet of levofloxacin). Cessation of the agents promoted complete recovery of these neurological adverse effects within the next two weeks. Both patients had no apparent neurological disorders except age-related brain atrophy. Age-related renal and brain impairment might have contributed to the neurological adverse effects of levofloxacin.

Chronic ethyl alcohol abuse is associated with different types of neurological involvement. We report a 51-year-old woman with alcoholic encephalopathy, neuropathy and autonomic dysfunction. After the alcohol abuse of about thirty years, gait disturbance, dysphagia and dysarthria progressively worsened. We thought that the disease was caused by poor nutrition due to chronic alcohol abuse and vitamin B1, B12 deficiency. Her neurological symptoms and signs improved after discontinuation of alcohol and nutritional treatment.

A Case of Marchiafava-Bignami disease demonstrated by MR diffusion-weighted image (DWI) was reported. A 55-year-old male with chronic alcoholism demonstrated dysarthria, disorientation and apraxia of left-hand. Sagittal view on MRI showed a swelling of the corpus callosum. The body and splenium of the corpus callosum showed symmetrically iso-intensity in T1 WI and hyperintensity in T2 WI, and remarkable hyperintensity in fluid attenuated inversion recovery images. DWI showed a definite hyperintensity area on the corpus callosum and the apparent diffusion coefficient (ADC) map presented the decreased water self-diffusion. These findings differed from the other demyelinating diseases, such as multiple sclerosis. We considered these DWI findings were the initial changes on MBD which preceded the demyelination. To our knowledge, this is the first report of DWI that was used in a case of Marchiafava-Bignami disease.

We report a sporadic case of spinocerebellar ataxia accompanied by later but severe involvement of the motor neuron system. A 72-year-old man began to show ataxia and dysarthria at age 66 years. Neurological examinations revealed saccadic eye movement, slurred speech, truncal ataxia, pyramidal sign, and urinary disturbance. Neither history of alcoholism nor hereditary factors were found. He developed muscular atrophy of the lower and upper extremities and limb ataxia within three years. Superficial and deep sensations were diminished in both feet four years after onset. Thus, he presented with cerebellar ataxia, bulbar sign, upper and lower motor neuron symptoms, sensory disturbance, and autonomic sign after six years at age 72. The level of serum, creatine phosphokinase (CPK) was increased, and muscle biopsy showed marked neurogenic change. Magnetic resonance imaging (MRI) revealed mild cerebellar and pontine atrophy. Although the combination of spinocerebellar ataxia and motor neuron disease is very rare, the present case suggests the inter-relation of the spinocerebellar and motor neuron systems, and presents peripheral neuropathy as a subtype of multisystem atrophy.

Marchiafava-Bignami disease (MBD) is a rare disorder of an unknown aetiology but strongly associated with alcoholism. MBD primarily affects the corpus callosum leading to confusion, dysarthria, seizures and frequently to death. Over 250 cases from all races and from almost all nationalities have been reported, most cases being alcoholics. We report two cases with a favourable outcome. Magnetic resonance imaging (MRI) demonstrated a typical lesion of the corpus callosum, in both patients. The patients, a 44-year-old male and a 40-year-old female, presented with depressed consciousness and a variety of other symptoms, but finally made a reasonably good recovery leading to home discharge. To the best of our knowledge, only one additional case of MBD from Scandinavia has been published. As alcoholism is a major public health problem in Scandinavia, we assume that MBD is underdiagnosed and/or under-reported. Non-specific general symptoms and encephalopathy in an alcoholic may harbour undiagnosed MBD. We suggest that the incidence of MBD may be higher and its prognosis may be milder than generally believed.

A 58-year-old woman began to show ataxia at age 45 and dysarthria at age 56. Neurological examination revealed slurred speech, truncal ataxia, and pyramydal sign. Neither history of alcoholism nor hereditary factors were found. The level of serum ammonia was increased. Brain MRI study showed a high signal intensity in the cerebral peduncle and globus pallidus and mild cerebellar atrophy on T1-weighted image. A portal-systemic shunt due to a shunt vessel was found between the left splenic and kidney veins although she did not show any other symptoms or signs due to liver cirrhosis. Her symptoms dramatically improved by an intravenous administration of branched amino acid. The present case suggests an importance in finding a treatable cerebellar ataxia.

Central pontine myelinolysis (CPM) is a demyelinating disease of the pons often associated with the demyelination of extrapontine areas of the central nervous system. Although the etiology and pathogenesis are unclear, CPM is usually associated with hyponatremia or its rapid correction, and chronic alcoholism is also a common underlying condition. We observed a 43-year-old man with diabetes mellitus who developed central pontine and extrapontine myelinolysis with no apparent evidence of hyponatremia, serum hyperosmolality or associated rapid correction, or history of alcohol abuse. On admission, the patient was lethargic with dysarthria, dysphagia, and mild tetraparesis and his face and lower extremities were severely edematous. Laboratory examination showed normoglycemia and normonatremia, although hypokalemia, elevated HbA1c, and nephrotic syndrome were also present. Magnetic resonance imaging (MRI) revealed abnormal signal intensity in the pons, the deep layers of the cerebral cortex, and the adjacent white matter consistent with central pontine and extrapontine myelinolysis. Generalized edema was reduced by the use of diuretics and extracorporeal ultrafiltration without significant changes of serum sodium or osmolality. His consciousness level and paresis gradually improved within a few weeks. Our patient is a rare case of CPM associated with diabetes without apparent evidence of sodium or glucose imbalances.

Marchiafava-Bignami disease (MBD) is a rare central nervous system disorder of an unknown etiology strongly associated with alcoholism. MBD primarily affects the corpus callosum leading to confusion, dysarthria, seizures and frequently to death. About 250 cases of different races and nationalities, mostly alcoholics have been reported. We report a single-case study of a 43-year-old woman with the history of severe alcohol abuse, who demonstrated typical picture of Marchiafava-Bignami disease (MBD) with fatal course. We reviewed the literature on cases of MBD.
