Chronic asthenia in patients who have undergone endocrine neck surgery.

2021

Introduction: The impact of chronic asthenia after thyroidectomy has been evaluated in two previous studies comparing total thyroidectomy and hemithyroidectomy. We compared its impact on patients undergoing thyroidectomy, parathyroidectomy for primary hyperparathyroidism, and cholecystectomy. Methods: Patients recruited for surgery (233 consecutive total thyroidectomies for non-toxic multinodular goiter, Group I, 43 consecutive parathyroidectomies for primary hyperparathyroidism, group II and a sample of 43 laparoscopic cholecystectomies, group III) were compared at three times: pre-operative, 6 months after surgery, 1 year after surgery. A brief fatigue inventory (BFI) was administered to …

Il trattamento medico e chirurgico nei pazienti affetti da iperparatiroidismo secondario e terziario. Revisione della letteratura

2017

Introduzione: L’iperparatiroidismo è un’alterazione fisiopatologica della secrezione di paratormone dovuta o da un rilascio autonomo e anomalo (iperparatiroidismo primario o terziario) da parte delle paratiroidi o da un’alterazione dell’omeostasi del calcio che stimola l’eccessiva produzione di paratormone (iperparatiroidismo secondario). Obiettivi: Il trattamento clinico dell’iperparatiroidismo secondario o terziario non è univoco. Sorge pertanto la necessità di una revisione delle attuali metodiche diagnostico-terapeutiche. Discussione: Nell’iperparatiroidismo secondario (2HPT) si ha una progressiva iperplasia delle paratiroidi e un incremento della produzione di paratormone. Tra le cause…

Reoperation for persistent or recurrent secondary hyperparathyroidism

2017

Background: Secondary hyperparathyroidism is a common acquired disorder seen in chronic renal failure. Its pathophysiology is mainly due to hyperphosphatemia and vitamin D deficiency and resistance. When medical treatment fails, subtotal and total parathyroidectomy with autotransplantation are the standard procedures, although both are associated with high recurrence rates.Methods and Results: 4 patients experienced persistence and 9 relapse. The first 4 were subjected to reoperation after 6 months for the persistence of symptoms due to the finding of a supernumerary adenomatous gland while the remaining patients at the reoperation showed in 5 cases 2 more glands in over thymic position, an…

Invasive Diagnostics and Therapy

2022

The book is an update on contentious or unsettled issues concerning invasive diagnostic and therapeutic challenges in cancer and related disorders, focusing on the surgical approach. Topics include recommendations for the best practice in using the surgery safety checklist, surgical strategies in a variety of thoracic cancers, renal cell carcinoma, tumors of parathyroid glands, mesothelioma, and bariatric surgeries. The focus is on the diagnostic and therapeutic challenges of aggressive cancerous entities, choosing the most beneficial modes for optimal outcomes and patient survival. Chapters also address radioimaging and therapy outcomes in different intracranial lesions leading to severe n…

[The role of the anesthesiologist in secondary hyperparathyroidism].

2010

In the last years the increasing of diabetes and hypertension has produced a considerable increase of patients with chronic renal failure; secondary hyperparathyroidism is one of the major complications. The resection of hyperfunctioning parathyroid tissue is the ultimate goal of the treatment. The preoperative examination by the anesthetist is the starting-point of the treatment. The anesthetist programs hemodialysis, the correction of fluid and electrolyte abnormalities and of the anaemia. In the operating room the anesthetist is involved in the careful monitoring of liquid infusion and anesthesiological procedure. The intraoperative parathyroid hormone (PTH) assay is an essential tool be…

The Effect of High Parathyroid Hormone Concentration on Calcitonin in Patients with Primary Hyperparathyroidism2)

2009

Serum calcitonin (CT), parathyroid hormone (PTH), and calcium levels were measured in 23 patients with primary hyperparathyroidism. PTH was determined by a midregion (M-RIA) and a carboxyl-terminal (C-RIA) specific PTH-RIA. Only 2 patients had elevated CT levels. In contrast to the findings in 46 healthy controls, the CT levels did not correlate with calcium levels. Patients who had the highest iPTH values showed a negative correlation between CT and iPTH (M-RIA (n = 7): R = -1.0000, p less than 0.001; C-RIA (n = 13): R = -0.5604, p less than 0.05). The results of the C-RIA were subtracted from those of the M-RIA. In 12 patients with the highest levels of intact PTH (M-RIA - C-RIA), serum P…

Calciphylaxie : une complication grave et méconnue de l'insuffisance rénale chronique terminale. À propos de deux cas

2005

Calciphylaxis presents like subcutaneous lesions with livedo reticularis leading to necrotic and painful ulcers, predominantly in the lower limbs and the abdomen. They initially simulate dermohypodermitis. Biology reveals secondary hyperparathyroidism, phosphocalcic metabolism abnormalities and state of hypercoagulability. Histological signs are constant: calcifications in the media of small and sub-cutaneous arteries, intimal hyperplasia and intravascular thrombosis. This complication occurs in 4% of end-stage renal disease patients. Its prognostic is awful with a rate of mortality of 60% due to sepsis. Treatment is based upon the normalization of phosphocalcic rates and local debridement.

Effekt von Calcium und Magnesium auf die Parathormonfreisetzung aus humanem Parathyreoidea-Gewebe in vitro

1982

The effects of calcium and magnesium on parathyroid hormone release from eight adenomas causing primary hyperparathyroidism and six hyperplastic glands causing hypercalcemic secondary hyperparathyroidism were investigated in vitro using single cell suspensions from the respective tissue. We observed suppression of parathyroid hormone release with increasing concentrations of either cation. The quantitative hormone secretions of both adenomatous and hyperplastic glands was identical.

Non-functioning parathyroid cystic tumour: malignant or not? Report of a case

2017

Parathyroid carcinoma (PC) is a very rare endocrine tumour, usually characterized by symptoms such as a neck mass, dysphonia, severe hypercalcemia exceeding 140 mg/L and elevated serum parathyroid hormone levels, even more than 5 times the upper limit of normal. Non-functioning parathyroid cancer is extremely rare and, in this case, its pre-operative diagnosis is often difficult. A 54-year old female patient, referring dysphagia and dysphonia, underwent neck ultrasound and neck CT. A left thyroid nodule, probably cystic, was found. It presented caudal extent on anterior mediastinum causing compression of the left lateral wall of the trachea. The preoperative calcemia was into the normal ran…
