PSEUDOHYPOPARATHYROIDISM: REPORT OF A CASE SHOWING BONY DEMINERALIZATION

Abstract
A 29-year-old male Negro with pseudohypoparathyroidism is descr. This is the 13th such patient to be reported. The findings included typical blood chemical changes (low serum Ca and high serum P), tetany, mental retardation, cataracts, basal ganglial and skin calcification, delayed eruption of the permanent teeth, mildly shortened metacarpals, and at least one attack of epilepsy. An unusual finding was considerably generalized demineralization of bone. Parathormone was without measurable effect on Ca or P metabolism. This is in contrast to idiopathic hypoparathyroidism where parathormone produces an increased P output in the urine and a rise in the serum Ca level.
