IntroductionMaturity Onset Diabetes of the Young (MODY) affects 1–2% of diabetic patients. Subtype 5 (HNF1β mutation) is rare (~1% of all MODY subtypes) and extra-pancreatic manifestations are often present (chronic kidney disease (CKD), liver disease and/or genitourinary malformations).AimTo report and review confirmed MODY 5 cases in an Endocrinology Department.Meth...

Introduction: Parathyroid adenoma is the most frequent cause of primary hyperparathyroidism (PHPT). In recent years minimally invasive surgical techniques have challenged the traditional bilateral neck exploration. There are different imaging techniques for preoperative location of parathyroid adenomas. In this study the authors review the role of Doppler ultrasound focusing on its safety, availability and affordability.Aim: To evaluate the role of Doppl...

Introduction: The usefulness of acute octreotide suppression test (OST) in the selection of patients with acromegaly for chronic somatostatin analogues (SA) treatment is still controversial.Aim: To investigate the predictive value of OST for long-term responsiveness to long-acting SA.Materials and methods: Retrospective study of 25 drug-naive patients (13 males) with active acromegaly, subjected to an OST (hourly serum GH concentra...

Introduction: Graves orbitopathy is the major extrathyroidal manifestation of Graves Disease (GD). The approach depends on its clinical activity and severity. Treatment and referral to specialized centers, with Endocrinology and Ophthalmology, has a strong impact on the prognosis of Graves’ Disease (GD) and GO.Cases report: We report four cases of DG with OG. Their characteristics and clinical evolution are shown in Table 1.<table boarder="1" ce...

Introduction: A third of pituitary adenomas are non-functioning. Classification depends on adenohypophyseal hormones expression and transcription factors.Aim: Characterize silent pituitary macroadenomas cases regarding their clinical data, treatment, histopathology and prognosis.Methods: We revised clinical process of patients followed in CHULC. Cases with non-access to clinical follow-up registries or exams were excluded.<p cl...

Introduction: Giant prolactinomas are rare pituitary tumours, more frequently found in men (9:1), defined by an unusually large size (>4 cm), significant extrasellar extension and prolactin levels above 1000 ng/ml. Although dopamine agonists (DA) are the first-line treatment, combined therapy with DA and surgery, or rarely radiotherapy, may be necessary particularly when tumour volume control is not achieved.Case presentation: A 60-year-old woman, wa...

Introdution: Prolactinomas in men are rare and the majority are macroadenomas. Some studies suggest that these tumors in men have higher proliferative activity and aggressiveness indicating gender-specific differences in biological behavior. Dopamine agonists (DA) are considered first-line therapy.Material/methods: Retrospective analysis of male patients diagnosed with prolactinoma between 2005 and 2016. Age at presentation, clinical, hormonal and image ...

Introduction: somatostatin analogs (SSA) are largely prescribed in acromegalic patients, whether as adjuvant or primary therapy. Response is variable and seems dependent of histological subtype. Intensity T2 signal in MRI has been related to granulation patern and accordingly with response to SSA.Objective: To evaluate whether T2 MRI signal is correlated with effectiveness of SSAMaterial and methods: Retrospective analysis of acrom...

Introduction: Medical therapy of acromegaly is indicated in patients who failed to achieve remission after surgery, with contraindication or refusal for surgical therapy or following radiotherapy in order to bridge the interval until complete remission.Objective: Evaluate the medical therapy – somatostatin analogs (SSA), dopamine agonist (DAs) and GH receptor-antagonist (Pegvisomant) – in acromegalic patients followed from 1988–2011.<p...

Introduction: The prevalence of palpable thyroid nodules in Graves’ disease (GD) is approximately 15%. Cytopathologic interpretation in GD is challenging due to frequent cytomorphologic changes, namely after radioactive iodine (RAI) therapy. Some of the few published studies regarding fine-needle aspiration (FNA) in patients with GD, suggest an increased risk of malignancy of thyroid nodules arising in GD patients. However, the results are inconsistent, and there is no co...
