Thyroid cancer derived from follicular cells (TCDFC) comprises well-differentiated (papillary and follicular) carcinoma, poorly differentiated carcinoma, and anaplastic carcinoma. Papillary thyroid carcinoma is the most common endocrine cancer, and its incidence is steadily increasing. Lethality and aggressiveness of TCDFC is inversely correlated with differentiation degree. In this review, an emphasis has been put on molecular markers involved in tumorigenesis of thyroid carcinoma with a focus on aggressive histotypes and the role of such biomarkers in predicting thyroid cancer outcome...

Thyroid is a one of the most important endocrine organs. Understanding the molecular mechanism underlying thyroid development and function, as well as thyroid diseases, is beneficial for the clinical treatment of thyroid diseases and tumors. Through genetic linkage analysis and exome sequencing, we previously identified an uncharacterized gene C14orf93 (RTFC, mouse homolog: 4931414P19Rik) as a novel susceptibility gene for familial non-medullary thyroid carcinoma, and demonstrated its function in promoting thyroid tumor...

BACKGROUND Cerebral venous thrombosis (CVT) is a rare but fatal complication of hyperthyroidism that is induced by the hypercoagulable state of thyrotoxicosis. Although it is frequently difficult to diagnose CVT promptly, it is important to consider it in the differential diagnosis when a hyperthyroid patient presents with atypical neurologic symptoms. CASE REPORT A 49-year-old Japanese female with unremarkable medical history came in with thyroid storm and multiple progressive ischemic stroke identified at another hospital...

BACKGROUND: Polymorphisms of the receptor for advanced glycation end products (RAGE) gene have been studied in various autoimmune disorders, but not in Hashimoto's thyroiditis. Also, increased oxidative stress has been described in patients with Hashimoto's thyroiditis. The aim of the present study was to investigate the possible role of two common RAGE polymorphisms (-429T>C, -374T>A) in Hashimoto's thyroiditis; in parallel we studied oxidative stress levels. MATERIALS AND METHODS: 300 consecutive euthyroid women were examined and classified into three groups: Hashimoto's thyroiditis with treatment (n=96), Hashimoto's thyroiditis without treatment (n=109) and controls (n=95)...

Down syndrome is the most common chromosomal abnormality among live-born infants. Through full or partial trisomy of chromosome 21, Down syndrome is associated with cognitive impairment, congenital malformations (particularly cardiovascular) and dysmorphic features. Immune disturbances in Down syndrome account for an enormous disease burden ranging from quality-of-life issues (autoimmune alopecia) to more serious health issues (autoimmune thyroiditis) and life-threatening issues (leukaemia, respiratory tract infections and pulmonary hypertension)...

Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...

BACKGROUND: The Birt-Hogg-Dubé (BHD) syndrome is a very rare autosomal dominant form of genodermatosis caused by germline mutations in the folliculin (FLCN) gene, which is mapped to the p11.2 region in chromosome 17. BHD commonly presents cutaneous fibrofolliculomas, pulmonary cysts, renal cell carcinoma, and recurrent pneumothoraxes. The disease is easily ignored or misdiagnosed as pneumothorax, pulmonary lymphangiomyomatosis (LAM), or emphysema. Follow-up and guidelines for managing recurrent pneumothoraxes in these patients are lacking...

INTRODUCTION: Recently, the G534E variant of the HABP2 gene was reported as the underlying genetic defect in a large kindred with non-syndromic familial non medullary thyroid cancer (FNMTC). Nevertheless, this postulated role was not confirmed in additional cohorts. Contrasting data are also available on HABP2 expression in the thyroid. OBJECTIVES: To investigate HABP2 as a potential susceptibility gene in a large series of 27 unrelated families with FNMTC and to test its expression in thyroid tumor and matched normal tissues...

Stress elicits neuroendocrine, autonomic and behavioral responses that mitigate homeostatic imbalance and ensure survival; however, chronic engagement of such responses promotes psychological, cardiovascular and metabolic impairments. Over recent years, the renin-angiotensin system has emerged as a key mediator of stress responding and its related pathologies, but the neuronal circuits that orchestrate these interactions are not known. These studies combine the use of the Cre-recombinase/loxP system in mice with optogenetics to structurally and functionally characterize angiotensin type-1a receptor-containing neurons of the paraventricular nucleus of the hypothalamus, the goal being to determine the extent of their involvement in the regulation of stress responses...

The prognostic role of molecular markers in papillary thyroid carcinoma (PTC) is a matter of ongoing debate. The aim of our study is to investigate the impact of RAS, BRAF, TERT promoter mutations and RET/PTC rearrangements on prognosis of PTC patients. We performed a search in four electronic databases: PubMed, Scopus, Web of Science and Virtual Health Library (VHL). Data of hazard ratio (HR) and its 95% confidence interval (CI) for Disease-specific survival (DSS) and Disease-free survival (DFS) were directly obtained from original papers or indirectly estimated from Kaplan Meier curve (KMC)...

Squamous cell carcinoma of thyroid is an uncommon, very aggressive neoplasm, having a poor prognosis and poor response to chemotherapy and radiotherapy. Surgery is the initial treatment of choice, although it often presents as a widespread disease at the time of diagnosis, usually with cervical swelling that causes most of the symptoms due to local infiltration or metastasis. Local infiltration from adjacent tumour and metastatic disease needs to be excluded from other primary epidermoid carcinomas, in order to make a correct diagnosis...

Omalizumab is very effective in the majority of patients with severe chronic spontaneous urticaria (CSU), but its mechanism of action is still unclear. In CSU the coagulation cascade is activated with an intensity that parallels the disease severity, and elevated plasma D-dimer levels are associated with a poor response to both antihistamines and cyclosporin. We measured D-dimer plasma levels before and after the first administration of omalizumab in 32 patients with severe CSU. A number of clinical and laboratory parameters were recorded, including the urticaria activity score, presence of angioedema, disease duration, C-reactive protein, anti-nuclear, and anti-thyroid antibodies...
