Introduction: Hypocalcaemia is a potential post-thyroidectomy complication. Patients with previous Roux-en-Y Gastric Bypass (RYGBP) are at increased risk of symptomatic hypocalcaemia refractory to treatment. This complication is rare and there is not consensus on how to act.Clinic case: Female with 34 years old, with a history of Obesity (BMI 45.7 kg/m2), submitted to RYGBP in 2013, with a total loss of 47 kg (current BMI 27.3 kg/m2...

Introduction: The SGLT-2 inhibitors (InibSGLT2) are the newest class of non-insulin antidiabetic drugs (ANI) for type 2 diabetes mellitus (T2DM) treatment. Currently is only available in Portugal, dapagliflozin. This pharmacological class have shown benefits in metabolic control (reduction of 0.5–0.8% HbA1c) and in weight loss (1–3 kg).Objective: Evaluate the impact of InibSGLT2 in patients with T2DM followed in a Diabetes department.<p cla...

Introduction: American Thyroid Association recommends that benign thyroid nodules should be revaluated 6–18 months after initial FNA and in case of stability the follow-up should be 3–5 years. However there isn’t any consensus about the periodicity of the follow-up.Aim: To evaluate the nodules in terms of function, size and malignancy in a 10-year follow-up.Methods: Retrospective study of 347 patients (543 benign thy...

Introduction: Postmortem studies have shown that a fifth parathyroid gland may be present in about 5% of patients with hyperparathyroidism. 1% of parathyroid glands are located in thyroid tissue. There’s a prevalence of 7–10% of thyroid ectopic tissue.Case report: A 53-year-old male, submitted to bilateral nephrectomy due to a Grawitz tumour at the age of 25. Under haemodialysis since then (with a rejected renal transplant in the past), he was ...

Introduction: Interaction between diabetes mellitus (DM) and an infection usually results in hyperglycaemia. However, there is data describing hypoglycaemia events related with the association between certain antibiotics and oral anti-diabetic drugs or insulin.Case report: Male, 73 years old, with history of hypertension, obesity and dyslipidaemia. DM type 2 was diagnosed 13 years ago with any macro or microvascular complications so far. Currently he&#14...

Introduction: Lithium therapy is commonly used in bipolar disorder treatment. Alongside the increasing prevalence of goiter and hypothyroidism, the sustaining use of lithium therapy is associated with several metabolic disorders, such as hypercalcemia and hyperparathyroidism (HPT).Case report: A 64-year-old woman with history of bipolar disorder treated with lithium for several years was referred to our department for evaluation of recurrent hypercalcemi...

Introduction: Ultrasound guided Fine-Needle Aspiration (USFNA) of Thyroid is the gold standard for diagnosis of thyroid nodules. Nowadays, many patients are under anticoagulation and antiplatelet medication. Some of the rare complications of USFNA are haemorrhage therefore it’s not clear if performing thyroid USFNA in hypo-coagulated patients increase that risk of complications or if this medication should be stopped before the procedure. Additionally the influence that t...

Introduction: Hypertriglyceridemia (hyperTG) may increase the risk of cardiovascular disease and values above 1000 mg/dl are a risk factor for pancreatitis, including non-fasting measurements. The American Heart Association suggested that providers could use nonfasting triglycerides >200 mg/dl to identify hyperTG states. When an elevated result is observed, a fasting triglyceride measure may be reassessed, with exception for extreme levels (for example approximately 1000 m...

The analogues of GLP-1(aGLP1) are a new class of anti-diabetic agents, administered subcutaneously for the treatment of Diabetes Mellitus type 2 (DM2). In the Portuguese market, there are two aGLP1 currently available: Liraglutide (once-daily administration) and Exenatide (once-weekly administration). They mimic the GLP-1, produced in the small intestine, stimulated by foods at this region, increasing the production of insulin, decreasing the satiety and slowing gastric emptyi...

Introduction: Primary Hyperparathyroidism (pHPT) is a calcium metabolism disease, resulting from one or more parathyroid glands hyperfunction. Ultrasonography and Technetium Sestamibi are, nowadays, the first line imaging techniques for diagnosis. Recently, a 4-dimensional computed tomography (4D-TC) protocol has emerged, presented in the last endocrine surgery guidelines. It is a dynamic imaging exam based on the parathyroid contrast uptake pattern, whose sensitivity and spec...
