BACKGROUND: There appears to be a lack of consensus whether preoperative vitamin D deficiency (VDD) increases the risk of postoperative hypocalcemia and decreases the accuracy of postoperative parathyroid hormone (PTH) in predicting hypocalcemia in thyroid cancer patients undergoing total thyroidectomy (TT) plus central compartment neck dissection (CCND). This study aims to address these issues. METHOD: All consecutive thyroid cancer patients who underwent TT plus CCND were retrospectively reviewed through a prospectively collected database between October 2015 and April 2016 in a tertiary referral hospital...

BACKGROUND: The superior parathyroid gland is known to be almost constant in its location under the false thyroid capsule. Could it be a landmark to point to the site of incision of the false thyroid capsule and find the plane of the recurrent laryngeal nerve (RLN) during thyroidectomy? METHODS: The study included 48 patients with benign goiter scheduled for hemithyroidectomy or total thyroidectomy; there were 16 cases of solitary thyroid nodules, 27 cases of multinodular goiter, and 5 cases of toxic goiter...

BACKGROUND: Metastatic pulmonary calcification (MPC) is rarely reported in primary hyperparathyroidism, especially MPC develops quickly. We report such a case here with a literature review. CASE PRESENTATION: A 41-year-old woman presented with cough and dyspnea. Data from clinical, radiological, pathological, technetium ((99m)Tc)-methylene diphosphonate (MDP) bone scintillation imaging, and (99m)Tc-methoxy isobutyl isonitrile (MIBI) thyroid imaging were studied...

Postoperative nonunion is not uncommon in the lower extremity, and significant morbidity can be associated with nonunion of the foot and ankle after surgical reconstruction. For the purposes of the present study, we retrospectively reviewed and compared a cohort of patients who had undergone elective foot and ankle reconstruction to better assess the modifiable risk factors associated with postoperative nonunion. We hypothesized that the presence of endocrine and metabolic abnormalities are often associated with nonunion after foot and ankle surgical reconstruction...

BACKGROUND: Type I gastric neuroendocrine tumors (gNETs) classically arise because of hypergastrinemia and involve destruction of parietal cells, which are responsible for gastric acid secretion through the ATP4A proton pump and for intrinsic factor production. METHODS: By whole exome sequencing, we studied a family with three members with gNETs plus hypothyroidism and rheumatoid arthritis to uncover their genetic origin. RESULTS: A heterozygous missense mutation in the ATP4A gene was identified...

Parathyroid cyst (PC) is a very rare condition. A case of intrathyroidal PC is being reported here in a 53-year-old woman who presented to the endocrine clinic with slowly progressive painless left anterior neck swelling for 1 year with no symptoms of thyroid or parathyroid dysfunction and no compressive symptoms. Ultrasound of the thyroid showed a well-defined cystic lesion measuring 4.7 × 3.6 cm in maximum diameter with internal echoes within the cyst located in the left lobe of the thyroid gland. Fine needle aspiration revealed colorless clear fluid with a high concentration of parathyroid hormone...

BACKGROUND: Endocrine surgeon localizes solitary adenoma (SA) in preoperative time by cervical ultrasound (c-US) and/or 99mTC Sesta MIBI scintigraphy (MIBI-S), but in clinical practice they often show discordant results. The aim of our study is to verify if c-US and MIBI-S have different sensitivity in preoperative localization of SA, depending on its localization, in planning minimally-invasive video-assisted parathyroidectomy (MIVAP). METHODS: This is a retrospective analysis of data (demographics data, preoperative localization of SA by US and MIBI-S, presence of associated thyroid disease, preoperative calcemia, preoperative serum PTH, surgical time, intraoperative PTH values, day 1 postoperative calcemia, definitive histological report) about patients consecutively submitted to MIVAP because of SA between January 2011 and January 2014 in the department of endocrine and general surgery of the University Hospital of Parma (Italy)...

OBJECTIVE: Evaluate the possibility of performing a complex vascular allotransplant of all neck organs including skin. SUMMARY BACKGROUND DATA: There are 2 previous attempts described in the literature, none of them being that complex. The first one is nonfunctional due to chronic rejection, the second one is viable yet considerably limited in complexity (no parathyroids, no skin). METHODS: The allotransplantation was performed simultaneously on 2 adjacent operating rooms, using microsurgical techniques...

Although the surgical procedures concerning the thyroid and the parathyroid glands are considered safe, the possible occurrence of complications (mainly hematoma and hypocalcemia) limit the short stay surgery. At our institution a 23-hour-surgery with overnight hospital stay for endocrine neck surgical procedures was introduced since 2004. The present case series analyses the institutional results. Over 1913 endocrine neck surgery procedures, 1730 patients (90,2%) were managed according to this model. Among these patients, 92 suffered from hypocalcemia, 12 from airways obstruction due to the hematoma, 5 from bilateral nerve palsy...

Contemporary molecular biology research tools have enriched numerous areas of biomedical research that address challenging diseases, including endocrine cancers (pituitary, thyroid, parathyroid, adrenal, testicular, ovarian, and neuroendocrine cancers). These tools have placed several intriguing clues before the scientific community. Endocrine cancers pose a major challenge in health care and research despite considerable attempts by researchers to understand their etiology. Microarray analyses have provided gene signatures from many cells, tissues, and organs that can differentiate healthy states from diseased ones, and even show patterns that correlate with stages of a disease...

Endocrine tumors of thyroid, adrenal and parathyroid glands may be due to germline and inheritable mutations in 5-30% of patients. Medullary Thyroid Carcinoma, Pheochromocytoma, Paraganglioma, and Familial Primary Hyperparathyroidism are the most frequent entity. Hereditary endocrine tumors usually have a suggestive familial history; they occur earlier than sporadic variants, are multifocal, and have increased recurrence rates. They may be present as isolated variant or associated to other neoplasms in a syndromic setting...

OBJECTIVE: Primary hyperparathyroidism (pHPT) is often accompanied by underlying thyroid pathology and 1 to 36% of these thyroid pathologies are malignant. How the identification of these lesions affects patient management is unclear. We present a single-center experience with the prevalence of concomitant thyroid cancer in patients who underwent parathyroidectomy for pHPT. MATERIALS AND METHODS: This was a retrospective cohort study. Two hundred-two patients with primary hyperparathyroidism included study...

Postoperative hypoparathyroidism (HypoPT) and hypothyroidism (HypoT) are the main endocrine complications after the surgical treatment for thyroid cancer. Postsurgical HypoPT can be transient, protracted or permanent. Its frequency varies according to the underlying cervical pathology, surgical technique, and mainly the experience of the surgeon. Risk factors for HypoPT include aggressiveness of the tumor, extent of surgery, the presence of parathyroid gland in the pathologic specimen, and surgeon experience...

All vertebrates possess a thymus, whose epithelial microenvironment is essential for T cell development and maturation. Despite the importance of the thymus for cellular immune defense, many questions surrounding its morphogenesis remain unanswered. Here, we demonstrate that, in contrast to the situation in many other epithelial cell types, differentiation of thymic epithelial cells (TECs) proceeds normally in the absence of canonical Wnt signaling and the classical adhesion molecule E-cadherin. By contrast, TEC-intrinsic activation of β-catenin-dependent Wnt signaling blocks the morphogenesis of the thymus, and overexpression of a secreted Wnt ligand by TECs dominantly modifies the morphogenesis not only of the thymus, but also of the parathyroid and thyroid...

Tumourigenesis is a relatively common event in endocrine tissues. Currently, specific guidelines have been developed for common malignant endocrine tumours which also incorporate advances in molecular targeted therapies (MTT), as in thyroid cancer and gastrointestinal neuroendocrine malignancies. However, there is little information regarding the role and efficacy of MTT in the relatively rare malignant endocrine tumours mainly involving the adrenal medulla, adrenal cortex, pituitary and parathyroid glands...
