What Causes Hypercalcemia?

Discussion Calcium homeostasis is regulated by mechanisms involving the absorption from the gastrointestinal tract, bone deposition and resorption, and renal excretion. To review Vitamin D homeostasis click here. Serum calcium is found in three forms: free (47%), protein bound (43%) and diffusable calcium complexes (10%).

Abstract Nuclear medicine studies evaluate physiology on a molecular level providing earlier detection of lesions before morphologic change is evident. 99mTc-MDP and 18F-fluoride bone scans detect osteomyelitis earlier than radiographs and computed tomography (CT); aid in diagnosis of temporomandibular joint disorder; and evaluate activity of condylar hyperplasia, extent of Paget disease, and viability of bone grafts. 18F-FDG PET/CT distinguish between soft tissue and bone infections and diagnose osteomyelitis complicated by fracture or surgery. FDG PET is more accurate than CT alone and has a major role in stagin...

CONCLUSIONS AND RELEVANCE: Red eyes, conjunctivitis, and anterior uveitis occur frequently in patients with Chikungunya fever. Systemic diseases, such as diabetes, hypertension, and cancer, may increase the risk of such ocular manifestations. Routine ophthalmic evaluation is warranted in patients with these medical conditions. The relevance of this study lies in the fact that this disease remains an important public health issue, since such ocular sequelae as may be present can range from mild to severe, either as an acute or a delayed manifestation.
