[Informed consent in thyroid and parathyroid surgery].
2005
The Authors outline the law problems and the practice implications of thyroid and parathyroid surgery from the point of view of the informed consensus of the patient, and expose the criteria they usually adopt in their clinical practice for such procedures. This problem is particularly important because is exceptionally needed in emergency; therefore the preoperative information must be completed as possible, illustrating the risks of the procedure and the possible solutions alternative to surgery.
Tertiary hyperparathyroidism: a review
2021
Abstract: Tertiary hyperparathyroidism (HPT III) occurs when an excess of parathyroid hormone (PTH) is secreted by parathyroid glands, usually after longstanding secondary hyperparathyroidism. Some authorities reserve the term for secondary hyperparathyroidism that persists after successful renal transplantation. Long-standing chronic kidney disease (CKD) is associated with several metabolic disturbances that lead to increased secretion of PTH, including hyperphosphatemia, calcit-riol deficiency, and hypocalcaemia. Hyperphosphatemia has a direct stimulatory effect on the parathyroid gland cell resulting in nodular hyperplasia and increased PTH secretion. Prolonged hypocalcaemia also causes …

Evaluation of the value of gradients for intact parathyroid hormone after total parathyroidectomy and heterotopic autotransplantation for renal hyperparathyroidism.Prospective long-term follow-up study.Teaching hospital, Germany.A total of 115 patients operated on for renal hyperparathyroidism between 1 August 1987 to 15 August 1997.100/115 had total parathyroidectomy with autotransplantation.Analyses of serum calcium, alkaline phosphatase, and intact parathormone in serum 1, 4, 8, 12, 18 and 24 months postoperatively and annually thereafter. Parathormone gradients were calculated as the ratio of the parathormone concentrations in the antecubital venous blood of the grafted and the non-graf…
Epitēlijķermenīšu scintigrāfiskā izmeklēšana ar planāro, SPECT un SPECT/CT metodi
2016
Bakalaura darba tēma ir “Epitēlijķermenīšu scintigrāfiskā izmeklēšana ar planāro, SPECT un SPECT/CT metodi”. Autors uzskata, ka tēmas aktualitāti nosaka scintigrāfijas izmeklējuma efektivitāte, epitēlijķemenīšu saslimšanas diagnostikā un tālākā ārstēšanā, piemēram, ķirurģiskā. Epitēlijķermenīšu scintigrāfija ir viena no visinformatīvākajām diagnostiskās radioloģijas metodēm, lai veiksmīgāk diagnosticētu dažādas patoloģijas, piemēram, primārs vai sekundārs hiperparatireoīdisms. Darba mērķis ir noskaidrot un salīdzināt planārās, SPECT un SPECT/CT metodes efektivitāti un to pielietošanu epitēlijķermenīšu saslimšanu diagnostikā un to precīzākas lokalizācijas noteikšanā. Darba uzdevumi ir noskai…
Prospective evaluation of parathyroid graft function after total parathyroidectomy and heterotopic autotransplantation in renal hyperparathyroidism b…
1998
The value of gradients for intact parathyroid hormone (PTH) in the assessment of graft function after total parathyroidectomy/autotransplantation for renal hyperparathyroidism was evaluated in a prospective follow-up study. Altogether 99 patients who underwent operation from August 1, 1987 to December 31, 1996 were prospectively investigated and reexamined postoperatively, including analyses of serum calcium, alkaline phosphatase, and intact PTH in the antecubital venous blood of both arms. The postoperative course is known for all patients. Of the 99 patients included in the study, 95 underwent one to nine reexaminations (median three) over follow-up periods of 1 month to 5 years (median 2…
Modified cryopreservation and xenotransplantation of human parathyroid tissue.
1999
Introduction: A modified cryopreservation technique for human parathyroid tissue was compared with the standard method using a programmed freezer. Methods: Total parathyroidectomy was performed in three groups of 6-week-old Rowett nude rats. Group I (control) underwent no transplantation of parathyroid tissue (n=9). After 10 days, the rats of groups II (n=15) and III (n=15) underwent xenotransplantation of 20 mg cryopreserved human parathyroid tissue, which had been stored in liquid nitrogen at –196°C for 1–22 months prior to xenotransplantation. The parathyroid tissue was derived from 15 parathyroidectomized patients with renal hyperparathyroidism. Two tissue samples were obtained from eve…
