Intraoperative Parathyroid Hormone Monitoring During Parathyroidectomy for Hyperparathyroidism in Waiting List and Kidney Transplant Patients
2006
This report describes the use of the intraoperative parathyroid hormone (ioPTH) assay during parathyroidectomy in waiting list and transplanted patients. ioPTH levels were determined in 40 patients on the waiting list for kidney transplantation with secondary hyperparathyroidism who underwent subtotal parathyroidectomy and 9 transplanted patients with tertiary hyperparathyroidism who underwent removal of hyperplasic glands. Rapid PTH levels decreased significantly at each time period; the percentage decrease in rapid PTH levels was 61.3% among patients with IPT II and 70.2% in patients with IPT III at 10 minutes and 86.5% in patients with IPT II and 91% in patients with IPT III at 15 minute…
BRAF(V600E) mutation influences hypoxia-inducible factor-1alpha expression levels in papillary thyroid cancer
2010
Abstract Hypoxia-inducible factor-1alpha is found frequently overexpressed in solid tumors cells, exerting an important role in angiogenesis, glucose metabolism, cell proliferation, survival and invasion. In thyroid carcinomas, hypoxia-inducible factor-1alpha expression was found increased in differentiated, poorly differentiated, medullary and anaplastic variants. Hypoxia represents the principal stimulus responsible for hypoxia-inducible factor-1alpha induction. Other nonhypoxic stimuli increase hypoxia-inducible factor-1alpha synthesis through the activation of phosphatidylinositol 3-kinase and mitogen-activated protein kinase pathways in a cell-type-specific manner. We have previously s…
BRAFV600E Mutation and p27kip1 Expression in Papillary Carcinomas of the Thyroid ≤1 cm and Their Paired Lymph Node Metastases
2007
BACKGROUND. BRAFV600E mutation and p27kip1 expression have been introduced as novel indicators that may predict prognosis in different tumors, as well as in papillary thyroid carcinomas. METHODS. Tissue samples from 214 consecutive patients who underwent total or near-total thyroidectomy with histological diagnosis of papillary thyroid carcinoma (PTC) ≤1 cm were analyzed for BRAFV600E mutation by a real-time, allele-specific amplification and for p27kip1 expression by immunohistochemistry. RESULTS. The BRAFV600E mutation was detected in 88 of the tumors examined, with significant differences between groups with and without lymph node (LN) metastases; the mean age of patients with BRAFV600E …
The importance of pyramidal lobe in thyroid surgery
2008
Pyramidal lobe (PL) is an embryological remnant of the thyro-glossal duct; its incidence varies from 15% to 75% but data concerning its size are lacking and limited to autoptic and radiologic evidences. Aim of our study is to elucidate the intraoperative frequency, location and surgical management of the PL.604 total thyroidectomy were performed between 1999 and 2007 in Unit of General and Thoracic Surgery of the University Policlinico of Palermo. The intraoperative incidence of PL was 12% (57% male, 43% female, mean age 42.5 years), but only about 50% were identified preoperatively with ultrasonography (US) (4% false positive) or with Tc-99m pertechnetate scintigraphy (8% false positive).I…
Hashimoto Thyroiditis Coexistent with Papillary Thyroid Carcinoma
2005
Several studies report a higher rate of papillary thyroid carcinomas (PTC) in patients with Hashimoto thyroiditis (HT), indicating a possible correlation between the two diseases. We studied a group of 89 subjects undergoing surgery for thyroid carcinomas compared with a control group of 89 subjects operated on for normofunctioning goiter, and a second group of 47 patients undergoing total thyroidectomy for HT. Association with HT was found in 19 of the 71 PTC subjects (26.7%) and in 8 goiter patients (8.9%), which was a significant difference ( P < 0.02). Thirteen of the HT patients, mostly with the nodular form, showed coexistent PTC (27.6%). HT and PTC coexisted in several morphologi…
Terminal ligature of inferior thyroid arterhy branches during total thyroidectomy for multinodular goiter is associated with higher postoperative cal…
2010
Purpose: To evaluate the impact of truncal versus terminal branch ligature of the inferior thyroid artery (ITA) on postoperative calcium and PTH plasma levels in patients undergoing total thyroidectomy for multinodular goiter. Methods: A prospective randomized study was performed comparing a group of patients that underwent either truncal ligature of the ITA (group 1) or terminal ligature of ITA branches (group 2). Results: A series of 126 consecutive patients with non-toxic euthyroid multinodular goiter underwent total thyroidectomy. Truncal ligature of the ITA was performed in 63 patients (group 1) and terminal branch ITA ligature in 63 patients (group 2). Postoperative ionized serum calc…
Results of the Thyroid Cancer Alliance international patient/survivor survey: Psychosocial/informational support needs, treatment side effects and in…
2013
To comprehensively assess the experience of a large, diverse cohort and identify potential care improvements, the Thyroid Cancer Alliance, an international patient/survivor group coalition, surveyed thyroid cancer patients/survivors worldwide.English, German, French or Spanish versions of a self-developed 43-item questionnaire were completed, predominantly online, by 2398 respondents from the US (37.9%), Germany (21.3%), the UK (11.5%), Canada (11.4%), France (9%), and 35 other countries. Females and differentiated thyroid carcinoma patients each comprised ~87% of respondents. Diagnosis occurred at age 30-59 years in 71.8%, within1 (1-5) year(s) before survey completion in 16.4% (55%).At di…
An evaluation score of the difficulty of thyroidectomy considering operating time and preservation of recurrent laryngeal nerve.
2018
The purpose of this study was to edit a renovated thyroidectomy difficulty scale (rTDS) in order to identify underlying thyroid diseases with a longer operative time and higher technical difficulty, also considering preservation of recurrent laryngeal nerve. We developed a renovated scale with a maximum score of 20 points by creating a form in which five variables were considered: vascularity, friability, mobility/fibrosis, gland size and difficulty in preservation of the recurrent laryngeal nerve. Two surgeons separately evaluated each of these. Through a simple linear regression analysis, we have analyzed the relationship between rTDS score and operative times, and between rTDS score and …
Local neck symptoms before and after thyroidectomy: a possible correlation with reflux laryngopharyngitis
2010
Objective Local symptoms in the neck such as swallowing, voice disorders and throat discomfort might be related to a goiter if present, but are also reported by patients suffering from reflux laryngopharyngitis. The aim of our study was to investigate the presence of reflux laryngopharyngitis in patients with nodular goiter before and after uncomplicated total thyroidectomy (TT) in order to evaluate if its presence could have any role in the origin of swallowing and voice alterations and throat discomfort. Study Design case series prospective study Setting hospitalized care in University Hospital Patients and Methods We consider twenty-five patients, affected by non-toxic nodular goiter and…
Does thyroid surgery for Graves' disease improve health-related quality of life?
2012
Abstract PURPOSE: Graves' disease can induce alterations of the psychosocial well-being that negatively influence the overall well-being of patients. Among the current treatments, surgery has limited indications, and its impact on the health-related quality of life has not been well clarified. The aim of this study was to assess the impact of surgery on the quality of life. METHODS: Fifty-seven patients who underwent total thyroidectomy for Graves' disease in our surgical unit between April 2002 and December 2009 were administered a questionnaire concerning four issues: organic alterations and clinical manifestations, neurovegetative system disturbances, impairment of daily activities, psyc…
