Context: Normocalcemic primary hyperparathyroidism (nPHPT) is defined by an inappropriately increased serum PTH with normal serum calcium. Information about the diagnostic yield of parathyroid SPECT/CT scan and ultrasonography in nHPPT is limited and not conclusive.
Purpose: To evaluate the positivity rate of Tc-Sestamibi SPECT/CT scan in nPHTP compared with classical hypercalcemic PHPT (cPHPT).
Context: Hypoparathyroidism is a rare disease and, as such, its natural history, long-term complications, and correct clinical management remain unclear.
Objective: To describe the natural history and clinical characteristics of the disease.
Design And Setting: To present a retrospective observational analysis from 7 specialized centers in Buenos Aires, Argentina.

Rotator cuff tears are known to be influenced by systemic diseases such as diabetes mellitus, hypercholesterolemia, thyroid disease, and osteoporosis.
