[Diagnosis of an osseous form of hyperparathyroidism].

Under observation were 66 (50.3%) of 130 patients with an ossific form of hyperparathyroidism. Fourty five patients showed the classical picture of Recklinghausen disease, and 21-only diffuse osteoporosis. The correct diagnosis would be established 4-5 years following the onset of the disease. During the period of most distinct manifestations pains in bones were noted in 93 per cent of cases. Two thirds of patients showed marked atonia and fatigue. Pathological fractures were multiple and were observed in 45 of 66 patients (totally 125 fractures). Great importance in establishing the diagnosis of the form of hyperparathroidism is attached to roentgenological investigation of all bones and biochemical assay of blood and urine.
