title: [Central pontine myelinolysis followed by frequent hyperglycemia and hypoglycemia--report of an autopsy case].
abstract: A case of central pontine myelinolysis (CPM) followed by hyperglycemia and hypoglycemia was reported. The case was 53-year-old female. Diabetes mellitus was found when she was 32 years old, insulin therapy was started at 37 years of age. Since she was 50 years old, proteinuria and ankle edema had developed and she was admitted to The Keihin Hospital. The peritoneal dialysis (PD) was performed next year, followed by the hemodialysis (HD). In January 1978, strange movements and the disturbance of her consciousness were occurred during PD, then blood glucose level showed over 1,800 mg/dl and serum osmolarity was over 390 mosm/KgH2O. Then she was diagnosed as non-ketotic hyperosmolar coma. After that, during HD and PD, hyperglycemia (approximately 1,200 mg/dl) and hypoglycemia (approximately 40 mg/dl) developed frequently. She died soon after HD on 19th December 1979. The autopsy disclosed bilateral atrophic kidneys due to diabetic changes and atrophic pancreas. Gross neuropathological findings revealed a few small infarcts at the putamen and the globus pallidus, however, other area were observed to be normal. The most remarkable change in microscopical finding was nearly symmetrical demyelinative lesion in the center of the basis pontis. The nerve cells and axon cylinders were relatively well preserved in the demyelinative lesion. The hyaline degeneration was observed in the arterial wall, however, any arterial obstruction was not found. Recent studies would suggest that the electrolyte disturbance, such as hyponatremia, may lead to CPM, particularly when this disturbance was rapidly corrected. On the other hand, CPM induced by diabetic coma has been reported, however, its pathogenesis has been unclear.(ABSTRACT TRUNCATED AT 250 WORDS)
