Introduction: Metastatic lesions to the oro-facial region may be the first evidence of dissemination of an unknown tumour from its primary site.
Case Presentation: We described a case of metastatic follicular thyroid carcinoma to the mandible presenting with pain and loosening of teeth in a 70 years old female patient leading to extraction of the loose teeth.
Conclusion: The present case emphasizes the importance of considering metastasis in the differential diagnosis of swelling related to loosening of teeth, even though the patient had no history of any malignant disease.

Objective: This study investigated the clinical significance of mutations in patients with distant metastatic follicular cell-derived thyroid cancer (FDTC).
Methods: This study included 310 Chinese patients with distant metastatic FDTC. We analyzed the interactions between mutations and other gene alterations and compared the clinicopathological characteristics of patients with pathogenic (P) or likely pathogenic (LP) mutations (n=9), other gene alterations (n=253), and no gene alterations (n=37).

Due to their high developmental diversity and different regulatory and functional roles, B cell subpopulations can promote or inhibit tumor growth. An orthotopic murine HNSCC model was applied to investigate the B cell composition and function in HNSCCs. Using flow cytometry approaches, cells from the spleen, lymph nodes and tumors were analyzed.

Xylene substances have wide industrial and consumer uses and are currently undergoing dossier and substance evaluation under Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) for further toxicological testing including consideration of an additional neurotoxicological testing cohort to an extended one-generation reproduction toxicity (EOGRT) study. New repeated dose study data on xylenes identify the thyroid as a potential target tissue, and therefore a weight of evidence review is provided to investigate whether or not xylene-mediated changes on the hypothalamus-pituitary-thyroid (HPT) axis are secondary to liver enzymatic induction and are of a magnitude that is relevant for neurological human health concerns. Multiple published studies confirm xylene-mediated increases in liver weight, hepatocellular hypertrophy, and liver enzymatic induction the oral or inhalation routes, including an increase in uridine 5'-diphospho-glucuronosyltransferase (UDP-GT) activity, the key step in thyroid hormone metabolism in rodents.

Background: Gonadotropin-releasing hormone agonists (GnRHa) are commonly used in assisted reproduction technology (ART) cycles to prevent a luteinising hormone (LH) surge during controlled ovarian hyperstimulation (COH) prior to planned oocyte retrieval, thus optimising the chances of live birth. We compared the benefits and risks of the different GnRHa protocols used.
Objectives: To evaluate the effectiveness and safety of different GnRHa protocols used as adjuncts to COH in women undergoing ART.
