We reported a family with dentato-rubro-pallido-luysian atrophy (DRPLA) and chronic renal failure. The proband was a 66-year-old woman who developed gait disturbance, limb ataxia, pyramidal tract signs, and dementia since age 54. T2-weighted brain MR images revealed symmetric high-signal lesions in the cerebral white matter, in addition to cerebellar, brainstem, and cerebral cortical atrophy. She suffered from renal failure and became dialysis-dependent at the age of 59, four years after the onset of chronic nephritic syndrome. At the age of 66, she was admitted to our hospital because of hyperthermia and disturbance of consciousness, and died of DIC. Her CAG repeats in the DRPLA gene were 58 and 12. An autopsy was performed. The brain weighed 910 g. Histological findings confirmed the diagnosis of DRPLA. Her mother died of chronic renal failure. All three siblings had cerebellar ataxia, and two siblings had chronic nephritic syndrome. Among them, only her younger brother was diagnosed as non-IgA glomerulonephritis based on kidney biopsy findings at the age of 48. Though the nature of the association between DRPLA and renal dysfunction remains obscure, the DRPLA gene abnormality may be correlated with chronic renal failure in this family.

We report a 58-year-old man with slowly progressive muscle atrophy and weakness in the four extremities, accompanying cerebellar ataxia and sensory impairment of all modalities. He was a product of consanguineous marriage. His neurological manifestations began in childhood. He was admitted to our hospital because of marked abdominal distension and pretibial edema with hypoalbuminemia and hyperlipidemia. Neuroimaging studies showed marked atrophy of the cerebellum and spinal cord. Nerve conduction studies presented with slowing and sural nerve biopsy revealed demyelination with onion-bulbs. Abdominal distension was interpreted to be caused by chronic idiopathic intestinal pseudo-obstruction (CIIP), leading to protein-losing gastroenteropathy and hypalbuminemia caused by the CIIP. He died of DIC by myelodysplasic syndrome and DIC, two years later. Postmortem study demonstrated with severe loss of anterior horn cells and gliosis in the spinal cord. The Clarke's column was also affected. There was symmetrical degeneration in the dorsal column and corticospinal tracts. The cerebellum showed atrophy of molecular layer, prominent loss of Purkinje's cells and sparse granular cell layer, but no obvious change in the dentate nucleus. Neuronal loss in the dorsal root ganglia was remarkable. There were no alternations in the cerebral cortex, striatum, thalamus, subthalamic nucleus, and pontine nucleus, except for mild changes in substantia nigra and inferior olivary nucleus. This case was clinically suspected either of variant of Friedreich's ataxia or an early onset ataxia associated with hypoalbuminemia (EOAHA), although marked autonomic dysfunction was atypical. But the postmortem study, demonstrated with marked neuronal loss in anterior horn cells and cerebellan cortex and rather suggested an independent category of this case.

Children with acute encephalopathy (AEP) or acute encephalitis(AE) show variable findings in the clinical manifestations and on the neuroimaging. Patients with AE present variable symptoms: disturbance of consciousness, seizure, ataxia, dystonia, abnormal behavior, apnea, and others. This variability depends on the location of lesions including basal ganglia, brain stem, cerebellum, or cerebral gray/white matter. In AEP, MRI findings can be categorized into (1) severe brain edema, (2) acute necrotizing encephalopathy, (3) cortical necrosis that appears 4-5 days after the onset, and (4) others. Serum AST elevates in approximately 50% of AEP patients, and among them around 60% develops DIC. The high AST group includes Reye syndrome(RS), mimic RS and AEP with shock syndrome.

In the type of heat illness, several medical terms such as heat syncope, heat cramp, heat exhaustion, heat stroke are included. But their Japanese medical terms are neither unified nor clearly defined. To eliminate this problem, the new classification for heat illness is proposed. By the severity of heat illness, they are divided into three grades. Grade I is corresponded to heat cramp and heat syncope. Grade III is corresponded to heat stroke, and used for any one of the three following clinical findings, (1) Central nervous system dysfunction, i.e., consciousness disturbance, seizure, ataxia. (2) Liver and kidney dysfunction. (3) Clotting disorder, i.e., DIC. This classification can be beneficial not only to the diagnosis in the hospital, but also to the early detection and management of heat illness in the field.
