    The Trousseau sign of latent tetany is another sign of decreased calcium in blood where muscles in the hand contract when the brachial artery supplying the area is occluded. The Trousseau sign of latent tetany also generally occurs earlier than the Chvostek sign and is a more accurate predictor of hypocalcemia, allowing clinicians to recognise ...

    Hyperphosphatemia causes acute kidney injury in tumor lysis syndrome, because of deposition of calcium phosphate crystals in the kidney parenchyma. [2] Hypocalcemia. Because of the hyperphosphatemia, calcium is precipitated to form calcium phosphate, leading to hypocalcemia. [2] Symptoms of hypocalcemia include (but are not limited to): [9] tetany
