Introduction: Sheehan syndrome (SS) is caused by postpartum necrosis of the pituitary gland, associated with significant haemorrhage during or after delivery. It is rare in developed countries, but still frequent in underdeveloped ones. We present a rare presentation of this syndrome.Clinical case: A 48 years old black woman presented at the emergency department for long term fatigue and dyspnea that worsened a few days before. Her physical examination r...

Introduction: Central diabetes insipidus (DI) is a frequent complication of transfenoidal surgery for Cushing’s disease (CD). It can be transient or, more infrequently, permanent. The most common mechanism results from surgical neurohypophyseal damage rather than local mass effect from the pituitary adenoma.Case report: A 40 years old woman was referred to our Endocrinology outpatient clinic at the beginning of 2015 for new onset hypertension, signi...

Introduction: Prolactinomas are mostly benign tumours usually managed with pharmacological treatment. Some, however, seem to be resistant to dopamine agonists (DA) for unclear reasons. The relationship between T2W signal intensity (T2WSI) and response to treatment with somatostatin analogs is well described in acromegaly patients. Some evidence suggests that prolactinoma’s T2W hypointensity might be related to higher baseline prolactin levels and more resistance to DA.</p...

Introduction: DIPNECH is a preinvasive condition in which there is an idiopathic generalised proliferation of pulmonary neuroendocrine cells that can form tumourlets. There are very few cases described of ACTH secretion by these cells causing Cushing’s syndrome, some of them cyclic.Case report: A 41 year-old woman was sent to our Endocrinology outpatient clinic for menstrual disturbance, acne and excessive sweating. She had a recent diagnosis of DIP...

Although primary hyperparathyroidism (PHPT) is usually cured by surgery, some individuals are unable to undergo parathyroidectomy and are refractory to standard calcium lowering medical therapy. In such cases, targeted therapy with cinacalcet may be useful.The aim of this study was to access the short-term efficacy of cinacalcet in lowering calcium (Ca2+) levels in patients with PHPT unable to undergo parathyroidectomy and refractory to standa...

Introduction: Type 1 diabetes mellitus (DM1) is frequently associated with other autoimmune diseases. Among children and adolescents, thyroid disease is the most common autoimmune endocrinopathy. The possibility of occult thyroid disease should be considered at diagnosis and when a patient is assessed at the annual review.Objective: The aim of our study was to determine the prevalence of autoimmune thyroiditis among children and adolescents with type 1 d...

Introduction: Gestational Diabetes Mellitus (GDM) is one of the pregnancy diseases with the highest rate of complications, influenced by several factors. Its prevalence has increased, with a prevalence of 7.2% in Portugal.Objective: Characterize pregnant women with GDM and evaluate the perinatal outcomes according to the country of origin and previous GDM.Material and methods: Cross-sectional and retrospective study. We collected c...

Introduction: Amiodarone is an antiarrhythmic iodine-rich drug, known to induce thyroid dysfunction both due to its high iodine content and through amiodarone-induced thyrotoxicosis (AIT), being this latter process classified into three different types. Type 1 is associated with increased thyroid hormone synthesis; type 2 is a destructive process with thyroid hormone release and type 3 is thought to be a mixture of the former two. Since treatment options are different, there h...

Paediatric Graves’ disease (PGD) is an uncommon autoimmune disorder with a multifactorial origin. Although, in some autoimmune endocrinophaties the seasonality of month of birth (MOB) distribution differed from the general population, this association has not been study in PGD. The aim of this work was to analyse the impact of seasonality of MOB on PGD incidence in Portugal.In 2013, the Portuguese Paediatric Society of Diabetes and Endocrinology und...

Introduction: Bartter syndrome represents a set of closely related autosomal recessive renal tubular disorders characterised by hypokalemia, hypochloremia, metabolic alkalosis and hyperreninemia with normal blood pressure. The underlying abnormality results in excessive urinary losses of sodium, chloride and potassium. Bartter syndrome is classified into 3 main clinical variants: neonatal Bartter syndrome, classic syndrome and Gitelman syndrome.Case repo...
