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.

Two patients with disulfiram-(Antabuse-)induced encephalopathy exhibited paranoid ideas, disorientation, impaired memory, ataxia, dysarthria, snout and grasp reflexes, and abnormal electroencephalograms. The first patient developed symptoms on two occasions, each time after disulfiram administration. The second patient experienced a generalized seizure followed by fulminant psychosis three weeks after starting disulfiram therapy. Spinal fluid examination in the latter patient revealed a low homovanillic acid (HVA) level. Since disulfiram inhibits dopamine oxidation, disulfiram-induced encephalopathy may be related to excess dopaminergic activity in the central nervous system.

Seventy individuals with ataxia telangiectasia were studied: 29 females and 41 males with an age range of 2 to 42 years. The majority (43/68) presented by 3 years of age with truncal ataxia. All had progressive, handicapping neurological symptoms exhibiting ataxia (70/70), ocular motor apraxia (70/70), an impassive face (70/70), dysarthria (70/70), chorea (68/70), dystonia (55/70) and peripheral neuropathy (50/70). Clinical immune deficiency was present in 43 of 70 patients. Ocular telangiectasia were seen in all but one case and excessive thinness in 54 of 70. The mean age of loss of walking was 10 years and of writing 8 years. All 60 tested showed increased sensitivity to ionizing irradiation, 43 of 48 had an elevated alpha-fetoprotein level and 14 of 21 had an immunoglobulin deficiency. Although there was a marked variation in disease findings sibs were always similar. The heterogeneity seen seems at odds with the unilocus linkage of ataxia telangiectasia to 11q23.

Neuropathological study of the visual pathway from the retina to the occipital cortex in Creutzfeldt-Jakob disease (CJD) has been scarcely performed. In the present study, pathological involvement of the visual pathway was observed in a 54-year-old man with CJD. The patient had the onset of visual disturbances in December 1985. He subsequently developed progressive dementia, right hemiparesis, ataxia and dysarthria, and rapidly fell into decerebrate posture in February 1986. In March 1986, myoclonus appeared on the whole body and EEG revealed periodic synchronous discharges, while brain CT and CSF findings showed no abnormalities. Myoclonus was observed most frequently from May to October 1986, and then reduced gradually. Brain atrophy on CT started from April 1986, and was progressive till the end stage of the disease. He died in January 1988, and the total clinical course was about 24 months. Neuropathological examination revealed severe degeneration of the cerebral cortex and the white matter. In the cerebral cortex, marked loss of neurons, astrogliosis, and spongiform changes were observed. In the cerebral white matter, the destruction of myelin sheaths and axons were evident. The cerebellum showed prominent loss of granule cells. These findings are consistent with those of the panencephalopathic type of CJD. In the visual pathway, loss of ganglion cells and bipolar cells in the retina, mild demyelination of the optic nerve, neuronal loss in the lateral geniculate body, and severe degeneration in the visual cortex were observed. The present case suggests that the neuropathological investigation in the visual pathway from the retina to the occipital cortex is important for clarifying the pathological processes in the visual system in CJD.

Six patients with bilateral paramedian thalamic infarction were seen in a general hospital over a 4 year period. This distinct stroke syndrome was recognized by the features of disturbed vigilance, often episodic, with vertical gaze disorder. Other signs included an amnesic syndrome, convergence difficulty, third nerve palsies, eyelid retraction, dysarthria, ataxia and involuntary limb movements. Diagnosis was confirmed by CT brain scan or magnetic resonance imaging. A variety of risk factors for stroke were present. All patients improved but two had significant residual disabilities.

A 39-year-old female presented to the Bryan Memory Disorders Clinic at Duke University with a 7-year history of an atypical progressive dementia, mildly impaired vertical gaze, dysarthria and mild ataxia. There was no evidence of organomegaly by clinical examination or by radionuclide liver/spleen scan. Brain biopsy disclosed a neuronal storage disorder characterized by ballooned neurons filled with oligo-lamellar cytosomes and lipid droplets. Cultured skin fibroblasts had diminished sphingomyelinase activity and impaired cholesterol esterification, although peripheral leukocyte sphingomyelinase activity was normal. Two years after biopsy, follow-up examination revealed marked progression of vertical gaze paralysis and ataxia. This case expands the clinical spectrum of Niemann-Pick disease type C by presenting in adulthood with subtle neurologic abnormalities; no visceromegaly and profound dementia.

A 28-year-old man developed slowly progressive dysarthria and gait disturbance over 7 years. Neurological examination revealed marked ataxia of articulation and gait, mild ataxia and spasticity of all four limbs without intellectual, visual, auditory, sensory or sphincter dysfunction. No physical signs of adrenal hypofunction were found. However, analysis of fatty acid of plasma sphingomyelin showed an increase in very long chain fatty acids, compatible with the diagnosis of adrenoleukodystrophy. Computed tomography disclosed marked atrophy of the cerebellum and pons, and bilateral low-density lesions in the deep while matter of the cerebellum. Magnetic resonance imaging showed these lesions more clearly, as well as other lesions in the middle and superior cerebellar peduncles, despite the absence of cerebral white matter involvement at the time of presentation. This is a rare case of adrenoleukodystrophy presenting as spinocerebellar degeneration and showing marked atrophy and several parenchymatous lesions of the cerebellum and brain stem.

A postal questionnaire was sent to all patients affected by hereditary ataxias and hereditary spastic paraparesis resident in the province of Turin (Italy) to study their diagnostic process. A 61% response rate was obtained. The mean time interval between onset and diagnosis was 6 years (1 to 32 years). The percentage of late diagnoses dropped from 59% before 1959 to 19% after 1970, mostly because a reduction of the interval between symptom onset and the first contact with the general practitioner. The onset with dysarthria and ataxia led to earlier neurologic consultation, but the whole time requested for the diagnosis was not modified. A reduction of the time needed for the diagnostic process may be important to address the family to an early genetic counselling.

A patient with hepatitis B virus-associated cirrhosis manifested various symptoms such as anemia, renal damage and neurological signs including cerebellar ataxia due to long-term administration of germanium-containing food. The patient was a 40-year-old male who had taken germanium containing mineral cheese for 26 months after he was diagnosed as having cirrhosis. Twenty four months after beginning to take the mineral cheese, he began manifesting paresthesia of the extremities, dysarthria and gait ataxia. Laboratory findings revealed anemia and renal damage. Biopsy of the peripheral nerve revealed loss of the large sheathed nerve, a characteristic feature of germanium intoxication. A high concentration of germanium (GeO2) was detected in patient's hair and urine. Cerebellar ataxia was characteristic in this patient, which was not reported in the previous papers.

We describe a 58-year-old patient with a rare predominantly venous vascular malformation of the medulla oblongata, which caused a progressive bulbar dysfunction consisting of hiccoughs, dysphagia, hoarseness, dysarthria, gait ataxia and dysuria over a period of 11 months. On autopsy, a large dilated vein with focal marked intimal fibroelastic thickening was present on the ventral surface of the medulla. Microscopically, moderate proliferation of capillaries and veins was observed which was confined primarily to the medulla. The veins displayed abnormal dilatation and tortuosity; prominent thickening of vessel walls was also present in the veins and capillaries. The venous abnormalities were prominent in the parenchyma of the medulla, but much less apparent in its subarachnoid space. Multifocal neuronal loss and gliosis were observed, most prominently in the inferior olives, hypoglossal, dorsal vagal and ambiguus nuclei. The histopathologic findings suggested that abnormal venous drainage within the parenchyma of the medulla was the most critical factor for the pathogenesis of this patient's neurologic symptomatology.
