Introduction: Therapy with hydroxychloroquine (HCQ) and chloroquine (CQ) constitutes a rare but documented cause of hypoglycemia in non-diabetic adults. The physiopathological mechanism is not fully understood, and symptoms may appear several years after starting treatment. In this paper, we describe the clinical presentation and investigation of a case of hypoglycemia attributed to HCQ therapy. Clinical Case: A 60-year-old female patient was referred fo...

Introduction: Bariatric surgery continues to stand as the most effective therapeutic intervention in treating severe obesity. However, a portion of patients experiences less satisfactory outcomes, diminishing the overall beneficial impact of this intervention. Identifying predictive factors for unsatisfactory responses to bariatric surgery could represent a crucial step in evaluating candidates, enabling the establishment of personalized care.Methods: Re...

Introduction: The simultaneous occurrence of two drug-induced thyroid dysfunctions is rare. We present a case of central hypothyroidism due to bexarotene (BXC), followed by Interferon-α (IFNα)-induced Graves’ disease (GD) thyrotoxicosis after 2 years.Case Report: A 56-year-old man with no prior thyroid disease was diagnosed with cutaneous T-cell lymphoma and commenced treatment with BXC 600 mg/day and IFNα 90 mg/week concurrently. Aft...

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading cause of chronic liver disease (CLD). Screening of liver fibrosis by clinical scores is recommended in people with obesity, but their accuracy is still under discussion. Vibration-controlled transient elastography (VCTE) is among the best validated imaging tools to assess liver fibrosis, and is suggested in patients with indeterminate or high-risk clinical scores....

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: Severe hypercalcemia is defined as a total serum calcium level >14 mg/dl or ionized calcium >10 mg/dl . The most common causes are primary hyperparathyroidism (PHPT) and neoplasms (90% of cases). Vitamin D intoxication is an extremely rare cause. Case Report: A 56-year-old man presented to the emergency department with vomiting, generalized weakness and complaints of imbalance over one week. Upon physical examination, he displayed c...

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: Metastasis to the thyroid gland is a rare phenomenon and is associated with primary tumors of the kidney, lung, breast, colorectal, and sarcoma. Thyroid metastases account for only 0.4-3.0% of all malignant neoplasms of the thyroid and occur more frequently in patients with goiter, thyroiditis, or nodules than in patients without previous thyroid pathology.Case report: A 57-year-old woman with a history of clear cell renal cell carcinoma (C...
