Introduction: Clinical manifestations of primary hyper-para-thyroidism (pHPT) had been dramatically changed during last 25 years. Evaluation of changes in clinical findings was the aim of this study.

Materials and methods: In a retrospective, descriptive case series, patients' records of all 47 pHPT (44 females, 3 males) from 1988 till 1998 were studied. Patients’ clinical presentations, signs and symptoms, laboratory and radiologic findings were reviewed and the results were compared with 34 patients' studied during 1978-1987. Serum Ca>10.5 mg/dl with increased or high normal PTH were the diagnostic criteria of pHPT.

Results: Patients’ age range was 11-70 and mean ±SD was 38±16 years, with a female to male ratio of 14:1. 57 percent of the patients had bone pain and muscle weakness, 12 percent were asymptomatic, 10 percent had pathologic fractures, 8 percent had renal stones, 8 percent had symptoms of hypercalcemia, and 2 percent had giant cell lesion. The mean±SD of serum calcium was 11.48±1.16 mg/dl, phosphorus was 2.4±0.6 mg/dl and 24-h urinary Ca was 294±197 mg. Serum PTH was increased from 1.5 to 500 folds. The frequency of single adenoma in right inferior, left inferior, and left superior gland were 43 percent, 30 percent, and 13 percent respectively.

Conclusion: In the study 12 percent of patients were asymptomatic whereas there was no asymptomatic case in the previous study. Prevalence of severe bone disease and the interval between onset of symptoms and diagnosis was also reduced. According to this study detection of pHPT in asymptomatic phase remarkably increased.
