PTH and hypoparathyroidism: Harrad et al. [78] presented a 28-year-old female at eight months following a caesarean section, during which time, the patient had been lactating; the authors demonstrated hypocalcemia on multiple occasions (1.45-1.54 mmol/L) (5.81-6.17 mg/dL), suppressed PTH, and a history of four grand-mal seizures, from which she was diagnosed with hypoparathyroidism and required intravenous calcium gluconate, followed by 2 g of daily cholecalciferol and a high-calcium diet.
