title: [A case of idiopathic hypoparathyroidism with extrapyramidal signs and insulin-dependent diabetes mellitus].
abstract: A case of a 29-year-old woman with idiopathic hypoparathyroidism was reported. There were neither endocrine nor neurological disorders among her family, except for her mother's hearing loss. She had been suffering from insulin-dependent diabetes mellitus since 21 years of age, and was noticed to be hard of hearing for several years, but never been examined. At the age of 27, choreic movement on her left upper limb and gait disturbance appeared. A year before admission, gait disturbance gradually developed and she could not walk any more. On admission, her height was 137.2 cm and her weight 36.5 kg. She had a round face, uneven teeth and borderline metacarpal sign on her right hand. On neurological examination, Parkinsonism, bucco-lingo-masticatory dyskinesia and bilateral extensor planter reflex were present, but tetany was not observed anywhere. Serum calcium was 3.9 mEq/l, and serum phosphorus 5.3 mEq/l. A CT scan of brain revealed calcifications in the bilateral basal ganglia and thalami, low density area in the left putamen, and atrophy of both caudate nuclei. Serum PTH was less than 100 pg/ml. Ellsworth-Howard's test showed hyperresponsiveness in the secretion of urinary phosphorus and cyclic-AMP. Other endocrinological studies showed no abnormality except for hyporesponsiveness in the secretion of insulin on glucose tolerance test. On the basis of these results, a diagnosis of idiopathic hypoparathyroidism with insulin-dependent diabetes mellitus was made. Administration of alfacalcidol returned serum calcium and phosphorus to normal with considerable clinical benefit. Parkinsonism was gradually improved and she became to be able to walk with a cane after one year of treatment. But buco-lingo-masticatory dyskinesia were not reduced.(ABSTRACT TRUNCATED AT 250 WORDS)
