Hepatic encephalopathy (HE) remains a diagnosis of exclusion due to the lack of specific signs and symptoms. Refractory HE is an uncommon but serious condition that requires the search of hidden precipitating events (i.e., portosystemic shunt) and alternative diagnosis. Hypothyroidism shares clinical manifestations with HE and is usually considered within the differential diagnosis of HE. Here, we describe a patient with refractory HE who presented a large portosystemic shunt and post-ablative hypothyroidism...

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...

BACKGROUND: Given that high-intensity focussed ultrasound (HIFU) of benign thyroid nodules often causes a massive release of thyroglobulin (Tg) into the circulation, we hypothesised a greater initial Tg rise may result in a greater nodule shrinkage 6 months after ablation. METHODS: One hundred and five patients who underwent HIFU for symptomatic benign thyroid nodule from 2015 to 2016 were analysed. Serum Tg and anti-Tg autoantibody were checked on treatment day (baseline) and 4 d after treatment...

In the modern era, a pathology report of thyroid carcinoma requires the inclusion of numerous prognostically relevant histopathologic features, e.g. the presence and extent of vascular and capsular invasion, extrathyroidal extension, the surgical margin status, and the characteristics of nodal metastasis. These pathologic features are crucial components of the initial risk stratification to determine the need for completion thyroidectomy and/or post-operative radioactive iodine ablation therapy. The current review aims to summarize the diagnostic criteria, the controversies, the prognostic impacts, and the challenges of these pathologic characteristics, focusing specifically on the parameters that are incorporated into the American Joint Committee on Cancer (AJCC) staging system, College of American Pathologists (CAP) reporting template, American Thyroid Association (ATA), and National Comprehensive Cancer Network (NCCN) guidelines...

The encapsulated and noninvasive follicular variant of papillary thyroid carcinoma has been recently reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). These tumors demonstrate indolent behavior. This change in nomenclature will have great clinical impact by avoiding overtreatment of patients with NIFTP lesions who in the past were diagnosed with thyroid carcinoma and typically received completion thyroidectomy followed by radioactive iodine ablation. The pathologic diagnosis of NIFTP requires surgical removal of the thyroid lesion or the lobe harboring it, and thorough sampling of the complete interface between the tumor capsule and the thyroid parenchyma, to exclude foci of invasion...

BACKGROUND: Although the incidence rate for thyroid cancer seems to have begun stabilizing in recent years, an increased rate of advanced stage of this disease has been reported. Additionally, distant metastasis is one of the most important prognostic factors of patients with papillary thyroid carcinoma (PTC). Unfortunately, the underlying mechanisms of distant metastasis as well as cell status like metabolism changes in distant metastatic tumors have not been clearly elucidated. OBJECTIVE: To identify serum metabolic signature of distant metastatic PTC...

In patients with differentiated thyroid cancer, stimulated thyroglobulin (sTg) levels after thyroid hormone withdrawal (THW) at remnant ablation (RA) and at 6 to 12 months are known to have good prognostic value. This study aimed to evaluate the prognostic impacts and best cutoff values of sTg levels under recombinant human thyroid stimulating hormone (rhTSH) treatment at RA and at follow-up. A total of 151 patients were enrolled, of whom 77 were followed up with rhTSH-stimulated Tg (rhTSH-sTg) and 74 with THW-stimulated Tg (THW-sTg) at 6 to 12 months after rhTSH-aided RA...

The majority of benign thyroid nodules are asymptomatic, remain stable in size and do not require treatment. However, a minority of patients with growing nodules may have local symptoms or cosmetic concerns, and thus demand surgical therapy. The timely use of ultrasound-guided, minimally invasive thermal therapies has changed the natural history of benign, enlarging thyroid nodules (TNs). These procedures produce persistent shrinkage of TNs and an improvement of local symptoms. Among the various procedures, percutaneous ethanol injection represents the first-line treatment for thyroid cysts, while in solid cold nodules, laser and radiofrequency ablation (RFA) have proven to be very effective and safe techniques in producing significant volume reduction that remains stable over several years...

In addition to xerostomia, taste dysfunction (hypo-, dysgeusia) is an independent side effect of radioiodine therapy of thyroid cancer. Hypogeusia results from damage of the small mucous salivary glands in the vicinity of the taste buds. Particularly in those patients, who are treated with drugs such as antidepressants or sedatives, taste dysfunction becomes frequently clinically symptomatic. If feasible, therapy regimens bearing a potential risk for taste dysfunction should be switched. Additional damage to taste function should be minimalized, including cessation of smoking, change of agents for dental hygiene, and change of toothpaste...

OBJECTIVE: Current diagnosis of radioactive iodine (RAI)-refractory (RAIR) differentiated thyroid cancer (DTC) is based on the imaging technique, which is of a high cost. Serum thyroglobulin (Tg) is a sensitive and easily obtained biomarker. Hence, we aimed to assess the predicting value of quantitative response of Tg in earlier identifying the RAIR-DTC with pulmonary metastasis. PATIENTS AND METHODS: Pulmonary metastatic DTC patients who underwent total or near-total thyroidectomy and at least two times of RAI therapy were included in this study...

A good aesthetic result in thyroid surgery is one of the main goals, as this procedure usually involves young women affected in clearly visible anatomical areas. To minimize the detrimental effects of scarring outcome, several therapeutic options have been employed. Lasers may be an alternative choice for prevention and treatment of post-surgical thyroidectomy scar. This paper reviews literature and the current knowledge on this topic. A comprehensive search in the Cochrane Library, MEDLINE and PUBMED databases was performed to identify relevant literature investigating the role of laser therapy in both prevention and treatment of unappealing scarring after thyroid surgery...

Thyroid hormones (THs) act in the brain to modulate energy balance. We show that central triiodothyronine (T3) regulates de novo lipogenesis in liver and lipid oxidation in brown adipose tissue (BAT) through the parasympathetic (PSNS) and sympathetic nervous system (SNS), respectively. Central T3 promotes hepatic lipogenesis with parallel stimulation of the thermogenic program in BAT. The action of T3 depends on AMP-activated protein kinase (AMPK)-induced regulation of two signaling pathways in the ventromedial nucleus of the hypothalamus (VMH): decreased ceramide-induced endoplasmic reticulum (ER) stress, which promotes BAT thermogenesis, and increased c-Jun N-terminal kinase (JNK) activation, which controls hepatic lipid metabolism...
