thyroid, parathyroid

Karin Gasser
A 10-year-old female Australian Cattle Dog was referred for investigation of a mediastinal mass. During clinical examination, a mandarin- sized mass was detected ventrally of the trachea. According to computed tomographic (CT) findings and cytology of a fine-needle aspirate, thyroid neoplasia was suspected. The assumed tumour affected the left thyroid gland and was staged as stadium II because of enlargement of the ipsilateral cervical and retropharyngeal lymph nodes. The left thyroid, including the parathyroid gland, was removed surgically with a guarded prognosis...

The adaptor protein-2 sigma subunit (AP2σ), encoded by AP2S1 , forms a heterotetrameric complex, with AP2α, AP2β, and AP2μ subunits, that is pivotal for clathrin-mediated endocytosis, and AP2σ loss-of-function mutations impair internalization of the calcium-sensing receptor (CaSR), a G-protein-coupled receptor, and cause familial hypocalciuric hypercalcemia type-3 (FHH3). Mice with AP2σ mutations that would facilitate investigations of the in vivo role of AP2σ, are not available, and we therefore embarked on establishing such mice...

BACKGROUND: Parathyroid glands can mimic thyroid follicular lesions on fine-needle aspiration (FNA) cytology and can lead to unnecessary or incorrect surgery. Newer molecular panel tests using next-generation sequencing (NGS) include analysis of cell type-specific gene expression profiles such as parathyroid. The study aim is to determine the frequency and clinical implications of parathyroid tissue identification by molecular testing in cytologically indeterminate "thyroid" lesions...

PURPOSE: Shear wave elastography (SWE) was described as valuable tool in the diagnostics of distinct types of thyroid lesions, thyroiditis and several other non-thyroidal conditions, such as liver inflammation and fibrosis or diagnostics of breast lesions. The aim of the current study was to assess the appearance of parathyroid adenomas in SWE and to check prospectively if SWE can be valuable additional tool in the diagnostics of pathologically enlarged parathyroids. METHODS: Patients with parathyroid adenomas confirmed by histopathology were included...

BACKGROUND: Thyroid disease occurs more frequently in patients with hyperparathyroidism than the general population and hinders parathyroid localization. Identifying thyroid pathology before operating improves management and avoids the risks of reoperation in the neck. This review assesses imaging studies in patients with hyperparathyroidism and thyroid pathology to identify the ideal imaging methodology for patients with multigland disease. METHODS: Systematic review of original articles reporting sensitivity or positive predictive value (PPV) for one or more imaging modalities in patients with hyperparathyroidism and thyroid disease...

Multiple osteolytic lesions are usually associated with metastatic involvement of the bone; however, metabolic bone diseases should also be included in the differential diagnosis. In this study, we describe a case of primary hyperparathyroidism (PHPT) with multiple osteolytic lesions that was diagnosed initially as having metastatic bone involvement. The laboratory results showed hypercalcemia and raised alkaline phosphatase along with fibrosis in the bone marrow biopsy with no increase in tumor markers and normal serum protein electrophoresis...

Background: The purpose of this study is to provide guidance for medical experts regarding malpractice claims on permanent hypoparathyroidism by analyzing the number of parathyroid glands (PGs) identified during thyroidectomy and the clinical outcome. Methods: Parathyroid findings were documented in a standardized protocol for 357 patients undergoing thyroidectomy and treated by a single specialized surgeon. The resected thyroid was routinely dissected for accidentally removed PGs with consecutive autotransplantation and the pathological report also described unintentionally resected PGs...

BACKGROUND: Careful parathyroid gland dissection and in situ preservation was the time-honored approach to prevent parathyroid failure after total thyroidectomy. The relative success of parathyroid autotransplantation of hyperplastic parathyroid tissue in patients with renal or hereditary hyperparathyroidism did popularize the use of normal parathyroid tissue autografts during thyroidectomy to prevent permanent hypoparathyroidism. Proof of autograft function in this setting, however, is controversial...

BACKGROUND: Parathyroid glands (PGs) exhibit autofluorescence (AF) when excited by near-infrared laser. This multicenter study aims to analyze how this imaging could facilitate the detection of PGs during thyroidectomy and parathyroidectomy procedures. METHODS: This was a retrospective Institutional Review Board-approved analysis of prospectively collected data at three centers. Near-infrared fluorescence imaging (NIFI) was used to detect AF from PGs during thyroidectomy and parathyroidectomy procedures...

BACKGROUND: Hypoparathyroidism, the most common complication after thyroid surgery, leads to hypocalcaemia and significant medical problems. An RCT was undertaken to determine whether intraoperative parathyroid gland angiography with indocyanine green (ICG) could predict postoperative hypoparathyroidism, and obviate the need for systematic blood tests and oral calcium supplementation. METHODS: Between September 2014 and February 2016, patients who had at least one well perfused parathyroid gland on ICG angiography were randomized to receive standard follow-up (measurement of calcium and parathyroid hormone (PTH) on postoperative day (POD) 1 and systematic supplementation with calcium and vitamin D; control group) or no supplementation and no blood test on POD 1 (intervention group)...

CONTEXT: Accurate preoperative localization of abnormal parathyroid tissue aids importantly in minimally invasive parathyroidectomy in patients with primary hyperparathyroidism. Vitamin D deficiency may possibly influence the success and characteristics of pre-operative localization because it is associated with more active disease and possibly larger adenomas. This could increase the sensitivity of the sestamibi to identify abnormal parathyroid tissue, but earlier reports are conflicting...

BACKGROUND: The relationship between the number of parathyroid glands autotransplanted and hypoparathyroidism as well as recovery of parathyroid function is not understood fully. The aim was to ascertain whether the number of autotransplanted glands affected the incidence of hypoparathyroidism and recovery of parathyroid function in long-term follow-up after thyroidectomy. METHODS: A retrospective cohort study included all patients with papillary thyroid carcinoma who underwent first-time total thyroidectomy with central neck dissection between June 2012 and June 2015...

Multiple endocrine neoplasia type 2A (MEN2A) is a hereditary syndrome. Here, two different RET proto-oncogen mutation were identified from family members of two MEN2A pedigrees by genetic screening. One RET mutations were found at codons 1893 and 1895 in exon 11 (1893-1895delCGA) from pedigree 1, which is a novel mutation, the other occurs at codon 634 (Cys634Arg) in exon 11 from pedigree 2. However, the clinical characteristics were similar in the patients of the two pedigrees. All the patients were in middle-age at onset...

BACKGROUND: The primary objective of this study was to determine rates of reoperation, ED visits, and hospital readmission after thyroid and parathyroid surgery at a tertiary hospital. A secondary objective was to determine if scores from the American College of Surgeons Surgical Risk Calculator (ACS SRC) predicted these events. METHODS: We retrospectively reviewed the records of patients undergoing parathyroid and thyroid surgery between 2011 and 2014. Patients who underwent an unplanned reoperation, returned to the ED, or were readmitted to hospital were evaluated using the ACS SRC...
