RESUMEN
INTRODUCTION: Hypocalcaemia is a common postoperative complication, both after the resection of parathyroid adenoma associated with primary hyperparathyroidism and after total thyroidectomy due to thyroid cancer or nodular goitre. For a few years, in patients with postoperative hypoparathyroidism and severe hypocalcaemia, who cannot discontinue intravenous calcium preparations even with the use of high vitamin D doses, attempts have been made to add recombinant human parathormone (rhPTH) to the treatment schedule. In this work, for the first time in Poland, we demonstrate the potential use of teriparatide for the treatment of severe hypocalcaemia based on three different cases of postoperative hypoparathyroidism. MATERIAL AND METHODS: Case 1. Female (52) with postoperative hypoparathyroidism, after total thyroidectomy and the removal of lower left parathyroid gland due to hyperparathyroidism, several weeks after the surgery still required intravenous calcium infusions because of tetany symptoms. Just one month of teriparatide treatment at 20 µg/0.08 mL given in daily subcutaneous injections proved sufficient to control calcium levels with oral calcium and vitamin D preparations during the next few days until total resolution of hypocalcaemia symptoms and the achievement and maintenance of laboratory normocalcaemia in the following weeks. CASE 2: Female (33) with hypoparathyroidism following total thyroidectomy in 1996 because of papillary thyroid cancer, with congenital tubulopathy associated with renal loss of calcium and magnesium, and the symptoms of tetany recurring since the day of surgery, requiring intravenous calcium administration every 2-3 days. Currently, the patient has been hospitalised because of venous port infection, the only venous access, which made intravenous therapy impossible. Because of the life-threatening condition of the patient, bridging teriparatide treatment was prepared (20 µg/0.08 mL). Complete resolution of clinical symptoms of hypocalcaemia was obtained with teriparatide doses given every 8-12 hours, which made dose reduction possible. Case 3. Female (52) after major oncological surgery because of laryngopharyngeal and cervical oesophageal cancer with the removal of parathyroid glands, fed through PEG, was admitted to hospital with the symptoms of tetany. Despite treatment intensification, the patient experienced a hypocalcaemic crisis during hospitalisation. Teriparatide treatment at 2 × 20 µg/day resulted in the resolution of tetany symptoms, with gradual normalisation of calcium-phosphate balance parameters during the following days. CONCLUSIONS: Based on the analysis of these cases, the conclusion was drawn that the use of recombinant human teriparatide allows for the control of severe hypocalcaemia requiring intravenous infusions of calcium in patients with postoperative hypoparathyroidism.

UNLABELLED: Toxic epidermal necrolysis (TEN) is a severe, life-threatening mucocutaneus adverse reaction, most commonly triggered by medication. Treatment in some aspects is still controversial. CASE REPORT: Patient with malignant astrocytoma, treated with palliative radiotherapy, developed massive erythema with bullae. Patient suffered from tumor-related epilepsy, treated pharmacologically with carbamazepine. After dermatological consultation TEN was diagnosed. The bacterial growth tests from blood were Staphylococci positive. An antibiotic therapy was performed and carbamazepine was withdrawn. Cyclosporine was administered. After 2 weeks of treatment, skin changes vanished and patient's condition improved. TEN could not be omitted in diagnosis of extensive skin changes because the causative drug removal is crucial for survival and pharmacological treatment varies in similar conditions. TEN as a drug-related disease more likely occurs in severely ill patients.
