Introduction: Papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC) are distinct neoplasms, associated with different histological findings. Their coexistence in the same patient is a rare event, requiring a different clinical approach.Clinical case: A 72-year-old patient with no family history of thyroid disease, underwent total thyroidectomy in February 2019, due to toxic multinodular goitre, with no evidence of postoperative complica...

Introduction: Oestrogens and androgens modulate the effects of growth hormone (GH). Sex differences have been described in acromegaly, with conflicting results in different populations. Additionally, data on sex differences in tumour histopathology are scarce.Aims: To analyse the influence of sex and menopause status in tumour characteristics and surgical outcomes in patients with acromegaly.Materials and methods: Retrospective coh...

Background: Hypercalcaemia due to primary hyperparathyroidism is a rare cause of acute pancreatitis, with a reported prevalence of 1.5–8%.Clinical case: A 25-year-old male patient was referred to the Endocrinology outpatient clinic for hypercalcemia diagnosed in the context of acute pancreatitis. He had medical and surgical pathological antecedents of: clavicle fracture after car accident, cholecystectomy and appendectomy, gastroesophageal reflux di...

Nonadherence to levothyroxine therapy is one cause of persistent hypothyroidism. To distinguish nonadherence from malabsorption, a levothyroxine absorption test (LAT) is sometimes required. The authors report a case of a 60-year-old female patient suffering from hypothyroidism resistant to oral levothyroxine (LT4) substitution after radioiodine therapy for Graves’ disease. Despite the continuous increases of LT4, over 10 years, to a maximum of 1 mg/d...

Introduction: Cushing’s disease (CD) is a rare disorder caused by an ACTH-secreting pituitary adenoma. Transsphenoidal surgery (TSS) is the recommended first-line treatment. However, an equivocal or even normal preoperative MRI can preclude the surgical management and the outcome of these patients.Objectives: Evaluate the relationship between preoperative MRI and TSS efficacy in patients with CD.Methods: Retrospective cohort s...

Introduction: Continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI) are forms of intensified insulin therapy and the most used regimens for type 1 diabetes (T1D). Owing to its continuous basal output, hypoglycaemic events tend to be rarer with CSII. Our goal was to evaluate the differences in nocturnal hypoglycemia between these two treatment strategies.Methods: Retrospective analysis of 61 patients who had performed continu...

Introduction: Gynecomastia is a frequent reason for endocrinology consultation and its correct investigation is pivotal towards a precise diagnosis. We present a clinical case of a rare cause of gynecomastia.Case report: A 56-year-old male was referred to the hospital setting for an endocrinology consultation. He noticed increased breast size for a year, initially tender to palpation, and unquantified weight loss. Neither galactorrhea, nor any nipple dis...

Introduction: Adrenocortical carcinoma (ACC) is a rare disease, with a severely adverse prognosis. Clinical reports, even when including a limited number of cases, can contribute to its knowledge. This study aims to characterize patients followed at our department between 1991 and 2013.Methods: Retrospective analysis of the clinical records of patients with pathological confirmation of ACC. Statistical analysis: SPSS21.Results: 22 ...

Introduction: The metabolic consequences of hyperprolactinemia and the repercussions of its treatment with dopaminergic agonists are not yet fully understood. This study aims to evaluate the metabolic profile of patients with prolactinomas (prevalence of diabetes mellitus, dyslipidaemia and obesity) and identify the potential variations after treatment with bromocriptine.Methods: Retrospective study of patients followed between 1962 and 2013. Included 17...

Introduction: On average, 40 to 50% of the patients with autoimmune adrenocortical insufficiency will eventually develop an autoimmune polyglandular syndrome (APS). Our aim was to characterize a population with primary adrenocortical insufficiency (AI) and determine the prevalence of other autoimmune disorders that might establish the diagnosis of APS.Materials and methods: We included patients with primary AI under surveillance at our Department. Those ...
