Introduction: Pituitary apoplexy is a rare disease which results of haemorrhage and/or infarction of pituitary gland. The optimal management of this problem still remains controversial between surgery and conservative treatment.Aims: To characterize the clinical presentation, diagnostic workup, treatment and follow up of patients with apoplexy. Methods:Retrospective study of 35 pituitary apoplexy followed in a portuguese hospital from 2006 to 2016.<p...

Introduction: Inferior Petrosal Sinus Sampling (IPSS) is the gold standard test to distinguish between Cushing Disease and ectopic ACTH secretion (EAS), mostly when the biochemical tests are discordant and/or there is no lesion in MRI.Aim: To evaluate the results of IPSS in the diagnosis of ACTH-dependent Cushing syndrome.Methods: Retrospective study that analysed IPSS results performed in the last decade in our centre and integrat...

Introduction: Pituitary surgery is currently considered the preferred treatment for Cushing’s disease (CD) and achieves remission in 55–85% of patients. Cortisol falls quickly after surgery, so that early post-operative cortisol level has been used as predictor of remission. There’s no agreement about optimal timing for cortisol measurement, with wide variability between centres.Objective: To assess the value of early post-operative serum ...

Introduction: Cushing’s disease (CD) is characterised by pathologic hypercortisolism caused by an ACTH-secreting pituitary adenoma. The primary modality for definitive treatment is pituitary surgery. The rarity of CD has made it difficult to establish reliable predictive factors of outcomes.Aim: Assessment of clinical, hormonal, radiological, surgical and histological findings as predictors of remission and relapse of CD.Metho...

Introduction: Amenorrhoea and galactorrhoea are manifestations that may allow earlier diagnosis of pituitary tumors associated with excess somatotropin (ST) and prolactin (PRL) levels.Objective: To evaluate clinical, analytical and imaging characteristics of ST and PRL producing tumors and its affect on diagnosis.Methods: Retrospective study including acromegalic patients diagnosed between 1982 and 2012. Information on clinical, an...

Introduction: Generously supported by IPSEN)-->Elevated levels of somatotropin (ST) and IGF1 in acromegalic patients are associated with high morbidity and mortality. The normalization of ST and IGF1 allows the reversal of most of their negative effects.Objective: To evaluate characteristics present at diagnosis, predictive of cure, after surgery, in patients with ST-producing tumors.Meth...

Introduction: The coexistence of Cushing’s disease with an ACTH-secreting adrenal adenoma is not frequent.Case report: A 32-year-old woman was observed in our Department in 2000 for obesity. Hypercortisolism was documented and the basal hormonal study and functional testing oriented towards a pituitary origin (ACTH 24.8 pg/ml). Pituitary magnetic resonance imaging (MRI) showed an asymmetric pituitary gland and a pituitary stalk deviation to the left...

Background: Radiotherapy (RT) with or without chemotherapy is a common treatment for head and neck squamous cell carcinoma (HNSCC) patients and it can cause adverse effects, including dysfunctions of thyroid. The aim of this study was to identify thyroid dysfunction among patients submitted to external RT for treatment of HNSCC, with serial evaluation of thyroid function.Material and methods: This is a retrospective longitudinal study of the follow-up of...
