Aim: Radioiodine activities for the treatment of Graves’ disease hyperthyroidism are still subject to discussion, as is the use of a fixed approach over a dosimetric one. We aimed to evaluate our success rate using a personalized dosimetric approach: instead of the “(MBq I-131×g gland mass×100)/(percentage uptake at 24 h)” activity calculation, we further adjusted for factors such as gender, age, diagnosis, 2 h and 4 h radioiodine uptake, previous medi...

Introduction: The Marine–Lenhart syndrome is a rare cause of hyperthyroidism that is associated with the simultaneous or sequential presence of characteristics related to Graves’ disease and toxic nodular or multinodular goiter. It’s validity as a disease is controversial and some authors believe that these are cases of hyperthyroidism where both etiologies coexist. The presence of hyperfunctioning nodules in Graves’ disease patients ranges between 0.8 and ...

Introduction: Functional islet β-cell tumours represent 1–2% of all pancreatic neoplasms. Diagnosing this type of tumour is often challenging because they present with unspecific clinical features overlapping more common syndromes. Diagnosis involves expensive testing, so, establishing whipple’s triad and excluding causes of exogenous hyperinsulinaemia is crucial before initiating investigation.Objective: To report a rare case of a proinsu...
