The adequate risk stratification in thyroid carcinoma, is crucial to avoid on one hand the overtreatment of low-risk and on the other hand the undertreatment of high-risk patients. The question how to properly assess the risk of relapse has been discussed during recent years and resulted in a substantial change in our approach to risk stratification in differentiated thyroid cancer, proposed by the newest ATA guidelines. First initial risk stratification, based on histopathological data is carried out just after primary surgery...

BACKGROUND: In anticipation of bundled-payment models for thyroid and parathyroid disease, a better understanding of resource utilization following surgery is required. We sought to characterize the use of hospital services following such operations using an analysis of readmissions. METHODS: Patients age 18+years who underwent a thyroid or parathyroid operation in CA or NY (2008-2011) were classified by procedure type. Primary outcome was readmission within 90 days...

OBJECTIVE: Familial dysalbuminemic hyperthyroxinemia (FDH) is caused by abnormal human serum albumin (HSA) with an increased thyroxine (T4) affinity leading to euthyroid hyperthyroxinemia. One- and two-step immunoassay of serum samples from FDH patients (e.g., Japanese patients) with the HSA R218P mutation can yield false-positive free thyroxine (FT4) results. Therefore, it is difficult to distinguish FDH from syndrome of inappropriate secretion of thyroid-stimulating hormone (e.g., syndrome of resistance to thyroid hormone, thyroid-stimulating hormone [TSH]-producing pituitary adenoma), even when multiple assays are used...

BACKGROUND: The veno-accompanying artery adipofascial (VAF) flap is nourished by accompanying vessels near large superficial veins. We examined whether the VAF flap can be applied to the external jugular vein. METHODS: Based on anatomic and angiographic studies, we performed reconstructive surgeries using external jugular veno-accompanying artery adipofascial (EJ-VAF) flaps. A retrospective chart review was performed for all patients who underwent this surgery. RESULTS: The presence of arteries accompanying the external jugular vein was confirmed...

BACKGROUND: Recurrent laryngeal nerve (RLN) palsy is a serious complication of thyroid surgery. During intraoperative neuromonitoring (IONM) of the RLN in thyroid surgery, repeated shifting between surgical instruments and the nerve stimulator is cumbersome and time-consuming. Therefore, we developed a simple detachable magnetic nerve stimulator that may be connected to all metallic surgical instruments. This study aimed to investigate the feasibility and efficacy of this detachable magnetic nerve stimulator for IONM in a porcine model and humans...

Although thyroidectomy under local anesthesia with monitored anesthesia care (LA-MAC) has been reported, reports of neck dissections beyond level VI under LA-MAC in patients with thyroid cancer are rare. We aimed to analyze clinical data and patient satisfaction levels during thyroidectomy and selective neck dissection by comparing LA-MAC and general anesthesia (GA) in adult patients undergoing these surgeries for thyroid cancer. The 60 enrolled patients comprised 50 patients that underwent thyroidectomy and 10 that underwent selective neck dissection; 30 underwent thyroidectomy (n = 25) or selective neck dissection (n = 5) under LA-MAC and 30 (matched patients) underwent thyroidectomy (n = 25) or selective neck dissection (n = 5) under GA...

Cervical hemorrhage due to non-traumatic, spontaneous rupture of the thyroid artery is rare, which usually results from arterial abnormalities or parathyroid or thyroid disorders. This report describes a 72-year-old woman who presented with a sore throat and slight neck swelling. Computed tomography (CT) revealed a large hematoma in the neck and mediastinum, due to extravasation from the major branch of the left superior thyroid artery. A follow-up CT the next day demonstrated that the extravasation had resolved...

The objective of this study was to prospectively evaluate the diagnostic accuracy of contrast-enhanced ultrasonography (CEUS) in differentiating between benign and metastatic cervical lymph nodes in patients with papillary thyroid cancer (PTC). Three hundred nineteen cervical lymph nodes (162 metastatic from PTC and 157 benign) were evaluated using conventional ultrasonography (US) and CEUS before biopsy or surgery. Metastatic lymph nodes more often manifested centripetal or asynchronous perfusion, hyper-enhancement, heterogeneous enhancement, perfusion defects and ring-enhancing margins than benign lymph nodes at pre-operative CEUS (all p values < 0...

BACKGROUND: Recent studies suggest that the encapsulated form of follicular variant of papillary thyroid cancer (eFVPTC) behaves more similarly to benign lesions and can be treated with thyroid lobectomy alone instead of total thyroidectomy. To distinguish aggressive cancers from more benign lesions more clearly, the objective of this study was to determine if the eFVPTC behaves less aggressively than the nonencapsulated variant (neFVPTC). METHODS: A prospectively collected endocrine surgery database in our institution was reviewed for all patients with FVPTC on surgical pathology from 1999 to 2012...

OBJECTIVES: Buprenorphine is a common analgesic in experimental research, due to effectiveness and having few side-effects, including a limited influence in the immune and endocrine systems. However, how buprenorphine affects cytokine levels and the adrenal and thyroid response during general anesthesia and surgery is incompletely understood. This study aimed to assess whether buprenorphine modulated significantly those responses in rats submitted to general anesthesia, mechanical ventilation, and surgical insertion of intravascular catheters...

Papillary thyroid carcinoma (PTC) is the most common subtype of thyroid malignancy and has a good prognosis and low mortality rate. Surgery is the standard treatment for patients with primary and recurrent thyroid cancer. Although patients with PTC usually exhibit excellent treatment outcome, the incidence of recurrence in the neck ranges from 20% to 59%. When a patient with thyroid cancer is contraindicated for surgery, ultrasound (US)-guided ablation techniques, including ethanol ablation (EA) and thermal ablations, are suggested alternatives...

OBJECTIVE: With the changing landscape of postgraduate surgical education to competency-based curricula, there emerges a need for alternative forms of training. Video teaching modules have been shown to be effective tools in surgical education, complementing traditional postgraduate curricula. There is a lack of validated modules described in the literature, specifically for teaching thyroidectomy. The primary objective of this study was to develop and validate a high definition video-based teaching module instructing thyroidectomy surgery to Otolaryngology-Head and Neck Surgery trainees...

Chest wall tumors are relatively rare, and hematogenous metastasis to the chest wall is very rare. We herein describe a rare case of occult thyroid carcinoma as metastasis to the chest wall in an 80-year-old woman. The patient received detailed examinations of the chest wall tumor, and the results suggested that she had occult thyroid carcinoma. Surgery was then performed to remove all of her thyroid. As a result, she was diagnosed with follicular carcinoma of the thyroid. We report an extremely rare case of occult thyroid carcinoma diagnosed as hematogenous metastasis to the chest wall...

CONTEXT: Bariatric surgery can lead to nutrient deficiencies. Gastric by-pass (GBP) entails restriction and malabsorption, whereas, vertical banded gastroplasty (VBG) is only restrictive. OBJECTIVE: The objective of this study is to study whether GBP-patients develop iodine deficiency from malabsorption, and if GBP- and VBG-patients develop lower 24-h urinary iodine excretion (24-UIE) than obese non-operated controls (OB-controls) due to lower iodine intake. DESIGN: The Swedish Obese Subjects (SOS) study is a prospective, non-randomized study of 4047 obese patients included 1987-2001, who chose bariatric surgery or non-surgical treatment...

The synchronous diagnosis of a thyroid metastasis and of the primary colon adenocarcinoma that produces it is very rare, with only 5 cases reported to date, all of them treated with thyroid surgery showing a mean survival of 7 months. An ¹⁸F-FDG PET/CT in an asymptomatic 74-year-old woman with a thyroid cytology suggestive of malignancy but uncertain about the origin of the tumor revealed an stage IV colon adenocarcinoma with KRAS mutation and multiple metastasis (thyroid, lung, and liver). A prompt therapeutic planning with chemotherapy allowed 21 months of survival...
