TRABAJO ESPECIAL MANEJO DE PACIENTES CON HIPOPARATIROIDISMO.

Hypoparathyroidism is an uncommon endocrine deficiency disease characterized by low serum calcium levels, elevated serum phosphorus levels, and absent or inappropriately low levels of parathyroid hormone (PTH) in the circulation. The disease may appear as an isolated disorder or in association with other organ defects. Usually the disease is identifiable as hereditary, although the most common acquired cause of hypoparathyroidism in adults is postsurgical. Patients with hypoparathyroidism most often present with paresthesia, cramps, or tetany, but the disorder may also manifest acutely with seizures, bronchospasm, laryngospasm, or cardiac rhythm disturbances. The major general distinction to be made is whether the hypocalcemia is associated with an absent or inappropriately low serum PTH concentration (hypoparathyroidism) or whether the hypocalcemia is associated with an appropriate compensatory increase in PTH. The anamnesis, phenotypical features, radiology evaluation and some biochemical profiles are determinant in an appropriate diagnosis. Symptomatic hypocalcemia can be a medical emergency requiring acute intravenous administration of calcium. The primary goals of chronic management include maintaining within an acceptable range the following indexes: serum total calcium, serum phosphorus and 24-h urine calcium excretion.
