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: Prolactinomas are the most common pituitary adenomas in paediatric patients, except in the first decade of life, when ACTH secreting adenomas are more frequent.Objective: Analysis of clinical, diagnostic and therapeutic data of prolactinomas in paediatric age.Methods: Retrospective study of 15 patients whose symptoms began before 18 years of age.Results: In girls, secondary amenorrhea (58.3%) an...

Pituitary carcinomas are rare and represent a challenge in clinical practice. Most secondary tumour localizations are intracranial and spinal, followed by liver, cervical lymph node, bone and, rarely, lung. PC frequently exhibit resistance to most usual therapies and the mean survival time is usually <4 years once metastases have been identified. Ectopic ACTH Syndrome is, in up to 50% cases, caused by lung tumours including carcinoids or Small Cell Lung Carcinomas (SCLC). ...

Giant prolactinomas are uncommon, with some individual case reports described in the literature, but with few series documenting treatment outcomes. They represent a therapeutic challenge, since restoring normoprolactinemia, eugonadism and reducing tumour size may not be realistic goals. Specific complications may also arise during treatment that change the initial management plans. The authors describe a case of a 28-year-old male with visual impairment and behavioural change...

A 36-year-old woman in follow-up due to early ovarian failure of idiopathic origin. No family history of interest. History of menarche at 12 years of age with regular menses until 18 years of age, when it begins with amenorrheic spells lasting up to 8 months. Laboratory tests revealed hypergonadotropic hypogonadism with negative ovarian autoantibodies, normal karyotype, and gynecological ultrasound showing a normal-looking uterus with slight bilateral ovarian atrophy. Negative...

Insulin autoimmune syndrome (IAS) is a very rare cause of hypoglycaemia in western countries. One proposed mechanism is anti-insulin antibody capture of prandial insulin followed by the dissociation of insulin from anti-insulin antibody. The first objective was to study the relationship between glucose, insulin and C-peptide during a prolonged glucose load in two patients with active IAS. The second was to study the variation of these parameters between the active and the reco...

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: Eating habits may contribute to longevity. Consumption of red meat, source of saturated fatty acids and cholesterol may be associated with increased risks of diabetes, cardiovascular disease (CVD), and mortality risk.Methods: We studied 521 subjects, both genders, 253 centenarians (CENT) (100.26±1.98 age) and 268 controls (67.51±3.25 age), both low (LCR) and high cardiovascular risk (HCR), calculated based on QRISK®2-2016. An...

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...

Spindle cell oncocytoma (SCO) is a rare entity with just 18 cases reported in the literature. It was first described in 2002 and was codified as a separate diagnostic entity in the 2007 WHO classification of brain tumours. SCO is a nonadenomatous sellar neoplasm with rich vascularization and intra and supra-sellar infiltration. Usual clinical presentation consists of headache, visual field defects and pan-hypopituitarism. The preoperative diagnosis is difficult due to a lack o...
