Doxifluridine, a new fluorouracil analog with a low myelosuppressive effect, has recently been subject to various disease-oriented, Phase II trials. For the present evaluation of drug tolerance, the Phase II data of 114 patients having received 376 doxifluridine cycles has been used. The treatment cycles consisted of 5 daily intravenous injections of 4,000 mg/m2 non-pretreated patients, and 3,000 mg/m2 in pretreated patients. Previous observations showing that doxifluridine is less myelotoxic than fluorouracil have been confirmed. 54% of the patients had no leucopenia (maintaining WBC counts over 3,000/mm3 and 90% had no thrombopenia (platelets not lower than 100,000/mm3) throughout treatment. However, a WHO grade 4 hematologic toxicity was observed in 9 patients, and 2 toxic deaths were related to severe granulocytopenia and sepsis. Digestive tract toxicity was similar and equally frequent as the one observed with fluorouracil: mucositis with oral ulcerations (19%), nausea and vomiting requiring specific treatment (8%) and severe but never hemorrhagic diarrhoea (5%). Neurologic toxicity was frequent, with 20% of patients complaining of somnolence and/or peripheral neuropathy, 7% of impaired consciousness and 1% of WHO grade 4 cerebellar ataxia. Among the 10% of patients with cardiac symptoms, 6% were benign and transient arrhythmias, and 4% were severe, including 1 myocardial infarction, 1 spontaneously reversible cardiac arrest and 2 ventricular fibrillations successfully treated with cardioversion. In spite of its encouraging antitumor activity and its good hematologic tolerance, intravenous doxifluridine, as used in this study, cannot be recommended because of the observed neurologic and cardiac toxicity. Oral doxifluridine is presently under investigation with preliminary results suggesting a lack of neuro- or cardiotoxicity.

A 60 year-old man was admitted to our hospital because of gait disturbance and dizziness. At 57 years of age, he noticed his walking unstable. After then, he had dizziness due to orthostatic hypotension, urinary difficulty, loss of livid, and forgetfulness. Neurological examination revealed he had severe orthostatic hypotension, cerebellar ataxia, dysarthria, hyperreflexia of four limbs, myoclonus of right leg, and atonic bladder. His brain CT showed cerebellar atrophy. Thereafter he had recurrent syncopic attacks. His gait disturbance progressed steadily, so he became bedridden. In his terminal stage, his limbs showed rigidity. About 3 years later he died of pneumonia and sepsis. At autopsy brain weighted 1,230 g. Glossly the putamens was bilaterally shrunken, the color of the substantia nigra and locus ceruleus became pale. Base of the pons and the cerebellum were atrophic. Microscopical examination confirmed the degeneration of striato-nigral and olivo-ponto-cerebellar systems without Lewy body. In the spinal cord there was depletion of neuronal cells in the intermediolateral nuclei and Onufrowitz nuclei. In addition to the conventional neuropathological staining methods, we performed the immunohistochemical studies using monoclonal antibody against synthetic peptide of beta protein which detected senile plaque of every stages with formic acid pretreatment, and compared to the modified Bielschowsky method and Congo red method. Our case showed many very primitive and primitive senile plaque in neocortices and hippocampal region. A few neurofibrally tangle were seen in hippocampus. We supposed our case might combine multiple system atrophy and Alzheimer' pathology.

An autopsy case of a 66 year-old woman is reported. She developed personality change and psychotic symptoms at the age of 58. She began to show gait disturbance and forgetfullness at the age of 60. She was admitted to Okayama University Hospital at the age of 61, when she showed personality change, dementia, cerebellar sings and chorea like involuntary movement. The illness progressed slowly and she died of septicemia at the age of 66. At autopsy brain weighed 990 g. Macroscopically, the atrophy of the brain stem was severe, and the cerebellum was slightly atrophic. Microscopically, the globus pallidus was almost intact, but the degeneration involved dentate nuclei, their projections, red nucleus and the subthalamic nuclei, so this case was considered to be a case of pseudo-Huntington form of dentatorubropallidoluysian atrophy, proposed by Hirayama. The most striking feature of this case was marked atrophy of the brain stem and her intense familial history. Investigation of her familial history revealed that there were 18 affected cases in 5 successive generations. Their onset of the disease varied from the age of 10 to 60 years old. Cases of juvenile onset showed myoclonus and convulsion as the initial symptoms, and convulsion as the initial symptoms, and those of presenile onset showed dementia, cerebellar ataxia and chorea like involuntary movement. And in some of these cases it was proved by NMR-CT that their brain stem were small. We discussed the meaning of the atrophy of the brain stem in these cases and the difference of the symptoms between the cases of juvenile onset and the cases of presenile onset.

The findings in 44 patients (42 of whom were chronic alcoholics) with central pontine myelinolysis show that the outcome does not depend on the severity of neurological deficits during the acute phase of the condition or on concomitant internal diseases, including the degree of hyponatremia. Of the 34 patients for whom follow-up data were available, 32 survived. Of these 11 completely recovered, 11 had some deficits but were independent, and 10 were dependent (4 through disorders of memory or cognition, 3 with tetraparesis, 2 with cerebellar ataxia, 1 with polyneuropathy). The electrophysiological findings did not contribute usefully to the prediction of outcome. Additional neuroradiological diagnostic testing with magnetic resonance imaging was also of no prognostic significance. The extent of the initial pontine lesion was not correlated with the severity of clinical findings during the acute phase of disease, nor was persistence of the pontine lesion as usually seen on magnetic resonance imaging correlated with clinical improvement. We conclude that patients with cerebral myelinolysis survive if the nonspecific secondary complications of transient illnesses such as aspiration pneumonia, ascending urinary tract infection with subsequent septicemia, deep venous thrombosis, and pulmonary embolism can be avoided.

Babesia (canis) rossi infection is common in dogs in South Africa, and frequently causes severe, life-threatening disease. Acidemia, persistent hyperlactatemia, hemoconcentration, elevated creatinine, cerebral babesiosis, pulmonary edema and pancreatitis are all associated with mortality rates above 30%, compared with overall mortality of 12% in admitted cases. Although half the admitted cases are severely anemic, hemoconcentration is associated with far higher mortality. Cerebral babesiosis is uncommon, but carries a poor prognosis. The pathological mechanism has been suggested to be endothelial cell damage and necrosis, followed by segmental microvascular necrosis with perivascular edema and hemorrhage. Renal involvement in babesiosis resembles the functional renal failure of sepsis. Hypotension is common, and other cardiovascular disturbances have been documented. Cerebellar ataxia, rhabdomyolysis and pancreatitis are recently identified complications. While the previous categorization into "severe" (life-threatening anemia) and "complicated" (complications not directly attributable to anemia) disease has proved useful, the distinction is artificial and probably unnecessary. An updated approach to classification is suggested, aimed at grouping animals by severity and prognosis, and using simple measures, such as clinical collapse and abnormal breathing, as much as possible. Although inflammatory mechanisms are undoubtedly important in the pathophysiology of babesiosis, there can be little doubt that tissue hypoxia plays a major role in the disease process.
