Introduction: Ectopic thyroid tissue is a rare embryonic developmental defect that occurs during the thyroid transition from its initial position in the floor of the primitive bowel to a pre-tracheal location. This defect has a prevalence in the general population of 0.3–1/100,000 inhabitants, increasing to 0.5–1/4,000 patients with thyroid pathology. It is more common in women and can be diagnosed at any age, with diagnosis being more common in young individuals.</p...

Introduction: Ophthalmopathy and dermatopathy are the most frequent manifestations of Graves Disease (GD). It is also known the relation between GD and other autoimmune diseases like myasthenia gravis. Thymus hyperplasia in GD is already documented on literature but it’s mechanism is not well understood. There are two possible explanations, one related to thyrotrophin receptors stimulation present on thymus, and other related to tissue stimulation due to generalized hyper...

Introduction: Ultrasound-guided fine-needle aspiration cytology (US-FNAC), the gold standard method to distinguish benign from malignant thyroid nodules, is the most accurate, cost-effective and minimal invasive preoperative test, aiming to resolve patient management. However, up to 30% of US-FNACs are classified as indeterminate nodules, making difficult to avoid unnecessary surgeries. Molecular tests may contribute to refine the preoperative diagnosis of thyroid nodules....

Introduction: Several studies recommend the use of molecular tests for a complete diagnosis of malignancy in thyroid carcinomas (TC). The study and identification of molecular markers in thyroid will contribute to a personalized and effective treatment of the patients. The development of TC has been associated with the activation of oncogenes that are implicated in the cell signaling pathway, interfering in cancer promotion and outcome. Moreover, the repertoire of microRNAs (m...

Introduction: Medullary thyroid cancer (MTC) is a rare tumour. Mostly sporadic, 25% are associated with multiple endocrine neoplasia (MEN2A/B) or isolated familial MTC. Surgery is the only curative option: its response is defined as complete (no evidence of biochemical or structural disease), incomplete (only structural response) and persistence of structural disease. We aimed to analyse the clinical and pathological factors associated with the prognosis of MTC.<p class="a...

Introduction: The interaction between obesity and bone metabolism is complex and not fully understood. Historically, higher body weight was considered to be protective against osteoporosis. This association has affected clinical practice: body mass index (BMI) is one of the variables included in Fracture Risk Assessment Tool (FRAX), where a higher BMI leads to a lower fracture risk. Despite this association between bone mineral density (BMD) and body weight, it is not clear wh...

Introduction: Medullary thyroid carcinoma (MTC) arises from thyroid parafollicular C cells and accounts for <5% of thyroid cancers. Nearly 25% occur in the context of multiple endocrine neoplasia type 2 syndrome (MEN2) or familial isolated MTC.Objectives: Evaluation of clinical characteristics and evolution of patients with MTC.Methods: Retrospective analysis of clinical records of patients with MTC diagnosed from 2001 to 2023....

Introduction: Factitious thyrotoxicosis is caused by intentional and surreptitious ingestion of thyroid hormone and can be a challenge in the differential diagnosis with other pathologies.Case report: Female, 35 years old, referred to our department for suspected subacute thyroiditis after COVID-19. The patient had previous medical history of hysterectomy, bilateral oophorectomy, 2 galactophorectomies with right breast reconstruction, depressive syndrome...

Introduction: The diagnostic gold standard for thyroid nodular disease is ultrasound-guided fine-needle aspiration cytology (US-FNAC), being the most accurate, cost-effective and minimal invasive preoperative test to distinguish benign from malignant nodules, aiming to resolve patient management. However, up to 30% of FNACs are classified as indeterminate nodules, turning difficult the decision on patient management to avoid unnecessary surgeries. The development of thyroid ca...

Introduction: Continuous glucose monitoring systems (CGM) have revolutionized the monitoring of diabetes, allowing real-time measurement of interstitial glucose levels. Although these devices are suitable for patients on insulin therapy, they are not yet routinely used in an inpatient setting. The difficulty observed in the glycemic control of hospitalized patients under intensive insulin therapy led to the development of a protocol to study the application of CGM in these pat...
