Introduction: New treatments of diabetes improve global metabolic status beyond glycemic control and achieve weight reduction in many patients.Case reports: We described four case reports to show GLP-1 agonists and dapaglifozin effects on metabolism and weight in patients with type 2 diabetes and obesity.Case 1 (Liraglutide): A 48-year-old man, hypertension, type 2 diabetes and extreme obesity. Baseline visit: treatment enalapril 2...

Introduction: Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare disease (1:4 million) characterized by a fatal premature aging. There are 162 cases worldwide, five of them in Portugal. It is caused by a sporadic autosomal dominant mutation in LMNA gene that encodes an abnormal variant of the laminin-A protein, named progerin. Although most babies born looking healthy, they begin to display some characteristics of Progeria around 18–24 months of life. The ear...

Case history: A previously healthy 39 year-old male presented to his optometrist with visual disturbance. Visual field perimetry confirmed bitemporal hemianopia, prompting referral to endocrinology. On questioning, he reported an increase in hand and shoe size, but no headache or diaphoresis. Examination revealed classical acromegaloid features including prognathism, spatulate hands and prominent orbital margins, as well as marked bilateral macro-orchidism.<p class="abstex...

Most differential diagnoses of unilateral adrenal lesions include non-functional adenoma, adrenocortical carcinoma or pheochromocytoma. Primary adrenal lymphoma(PAL) is an extremely uncommon type of primary extranodal non-Hodgkin’s lymphoma(<1%). Most cases are bilateral (~75%), being unilateral PAL scarcely reported. The apparent unilateral involvement of this entity at presentation, in the CT scan/MRI may difficult the diagnosis, delaying the start of chemotherapy. ...

Introduction: The T-Coach® telephone support program for patients with type 2 diabetes (DM2) treated with insulin glargine 300 u/ml, facilitates dose adjustments of basal insulin therapy through regular telephone consultations and offers diabetes education in order to improve empowerment of the patient. Objective: To assess the usefulness of the T-Coach® program in metabolic control and degree of satisfaction in patients with T2DM.Patients and ...

Introduction: Continuous subcutaneous insulin infusion (CSII) therapy in type 1 diabetes (T1D) reduces the risk of hypoglycemia. Hypoglycemia remains a treatment-limiting factor. Impared hypoglycemia awareness (IHA) occurs in 25% of T1D cases and seems to be underestimated by continuous glucose monitoring (CGM). Glycemic variability (GV) is a increasingly valued parameter as a predictor of hypoglycemia and risk of chronic complications.Objective: Analysi...

Background: In type 1 diabetes (T1D), quality of life (QoL) and the effectiveness of treatment influence each other. QoL has been associated with glycaemic control assessed by HbA1c in T1D on continuous subcutaneous insulin infusion (CSII), but data on the relationship between Continuous Glucose Monitoring (CGM) metrics and QoL are scarce.Objectives: To assess QoL and the association between CGM metrics and QoL in T1D on CSII.Metho...

Introduction: Familial neurohypophyseal diabetes insipidus (FNDI) is a rare form of central diabetes insipidus (CDI) characterized by childhood-onset progressive polydipsia and polyuria due to mutations in the arginine vasopressin-neurophysin II (AVP-NPII) gene.Case description: Two male siblings were referred at 1 month of age to exclude CDI owing to a family history of CDI in the father and paternal grandfather. The proband was the fa...

Introduction: Inferior petrosal sinus sampling (IPSS) has been considered to be the gold standard for differential diagnosis of Cushing’s Disease (CD) and ectopic ACTH secretion (EAS).Aim: To describe the experience of our centre in performing IPSS, its safety and efficacy; assess remission rates from transphenoidal surgery and clinical course; approach to the difficulty in the etiological diagnosis of ACTH-dependent Cushing’s Syndrome.<p c...

Introduction: Polycystic ovary syndrome (PCOS) is a frequent cause of infertility. Its influence on the results of in vitro fertilization (IVF) is controversial, and generally not isolated from the effect of obesity. A relationship between the FSH receptor (FSHR) polymorphism Asn680Ser and the risk and phenotype of PCOS has been studied with conflicting results.Objectives: To analyze the influence of obesity and PCOS on the gonadal axis...
