Bilateral inferior petrosal sinus sampling and the outcome of transsphenoidal surgery in patients with Cushing’s disease: experience of a Tertiary Portuguese Hospital

Gomes Ana Coelho , Neto Lia Lucas , Tortosa Francisco , Carvalho Maria Raquel , Barreiros Eduardo , Barreiros Luis , Miguens Jose , Bugalho Maria Joao

Introduction: Bilateral inferior petrosal sinus sampling (BIPSS) is the gold-standard for the differential diagnosis of ACTH-dependent Cushing Syndrome when the pituitary adenoma on MRI is doubtful or absent. This study aimed to analyze whether BIPSS can influence the outcome in patients with Cushing disease (CD).Methods: Retrospective, descriptive study. Forty-two patients with CD submitted to transsphenoidal surgery (TS) between 2005 and 2016 were divi...

Cushing’s disease: is there a Continuum from corticotroph hyperplasia to adenoma?

Gomes Ana Coelho , Neto Lia Lucas , Tortosa Francisco , Carvalho Maria Raquel , Barreiros Eduardo , Barreiros Luis , Miguens Jose , Bugalho Maria Joao

Introduction: Successful long-term management of patients with Cushing’s disease (CD) remains a challenge. Few studies have analyzed the long-term recurrence rates of CD after transsphenoidal surgery (TS).Objectives: 1) to compare the outcome of patients with and without postoperative criteria for cure; 2) to compare the outcome of patients with and without a histological diagnosis of adenoma.Methods: Retrospective, descriptiv...

Inferior petrosal sinus sampling in ACTH-dependent Cushing's syndrome: experience of a Tertiary Portuguese Hospital

Gomes Ana Coelho , Neto Lia Lucas , Carvalho Maria Raquel , Barreiros Eduardo , Aragues Jose Maria , Barreiros Luis , Campos Jorge , Mascarenhas Mario Rui

Introduction: Cushing’s disease (CD) is responsible for 80% of endogenous Cushing’s syndrome (CS). However, distinguishing the cause of ACTH-dependent CS – CD vs ectopic CS – can be extremely difficult. Bilateral inferior petrosal sinus sampling (IPSS) has the highest diagnostic accuracy in this evaluation.Objectives: The aims of this study were to determine the accuracy of bilateral IPSS in the differential diagnosis of ACTH-dependen...

Type 1 diabetes mellitus and acquired hemophilia

Bello Carlos Tavares , Fonseca Ricardo , Barreiros Catarina , Duarte Joao Sequeira , Esteves Jose , Vasconcelos Carlos

Introduction: Type 1a Diabetes (DM1) is a challenging disease with a rising incidence (up to 40 per 100 000 in Finland and Sardinia) being less common in the African population. It is believed to have an autoimmune basis and has been associated with other autoimmune diseases namely autoimmune thyroiditis and celiac disease. Acquired hemophilia is a rare clinical entity characterized by bleeding diathesis induced by circulating inhibitors to coagulation factors (VIII ou IX) tha...

The prevalence of colorectal cancer and colon polyps in acromegaly: thirty years’ experience of a tertiary referral center

Gomes Vania , Barreiros Luis , Barreiros Eduardo , Ferreira Florbela , Gomes Ana , Martins Ana Filipa , Osorio Ana Sofia , Wessling Ana , Silvestre Catarina , Reis Dinis , Nobre Ema , Carvalho Maria Raquel , Mascarenhas Mario , Vale Sonia do , Miguens Jose , Bugalho Maria Joao

Introduction: Several studies suggest a higher risk of colorectal cancer (CRC) and colon polyps (CP) in acromegaly, however there is still controversy regarding associated factors (AF) able to contribute for its development. Data on the prevalence of CRC and CP in Portuguese patients with acromegaly are limited.Objectives: To assess the prevalence of CRC and CP in acromegalic patients and compare to the normal Portuguese population. To determine the rele...

Introduction: Acromegaly is a rare disease resulting from pathological oversecretion of growth hormone (GH) and insulin-like growth factor-1 (IGF-1). The clinical spectrum includes cardiovascular and respiratory diseases but also increased risk of benign and malignant neoplasms.Objectives: Evaluate the prevalence of cancer and seek for associated factors in acromegaly.Methods: Retrospective study of 94 patients with acromegaly trea...

Energy deficit as a cause of transient male hypogonadotropic hypogonadism: a successful resolution of a primary infertility

Benido Silva Vania , Teresa Pereira Maria , Rossano Louro Nuno , Barreiro Marcia

Introduction: Caloric restriction combined with overtraining can result in a total body energy deficit, which in turn is associated with multiple deleterious endocrine consequences, including hypogonadotropic hypogonadism. This can be a reversible cause of primary infertility, but its occurrence in men is still poorly recognized.Case Report: We report a case of a 39-year-old male evaluated in an urology appointment for primary infertility. He had a histo...

Estrogens block the apoptotic action of tgfb in human thyrocytes

Garcia-Rendueles M. , Bravo S. , Rodrigues J. , Garcia-Rendueles A. , Barreiro F. , Cameselle-Teijeiro J. , Alvarez C.

Introduction: Multinodular Goiter (MNG) is a thyroid neoplastic disease thirteen times more common in women than in men. While a local effect of estrogens at cellular levels could affect there can be other causes to explain the gender difference in incidence such as diet, environmental factors, genetic causes or alterations in metabolic pathways.Cellular effects of estrogens in human thyrocytes although previously studied are not completely clarified. So...

Introduction: Pituitary tumours are considered benign, however some exhibit an aggressive behavior. Defining a timely treatment is challenging due to absence of accurate prognostic predictors.Objective: To evaluate radiological and histopathological features of aggressive pituitary tumours.Methods: Multicenter and retrospective study. Criteria for aggressiveness were: invasion to sphenoid and/or cavernous sinus; growth progression ...

Inhibition of proliferation in anaplastic thyroid cell lines

Rodrigues Joana , Rodriguez Angela , Perez Sihara , Barreiro Francisco , Cameselle-Teijeiro Jose , Rodriguez Maria , Bravo Susana , Alvarez Clara

Introduction: Our group has a bank of human primary thyroid cultures (BANTTIC) obtained from patients. All are individual cultures specifically genotyped and phenotyped. We believe of great interest the search for biomarkers in these cultures using differential proteomic analysis.We have applied differential proteomics using 2D-PAGE coupled to MALDI-TOF-TOF-MS. We have compared benign pathologies (normal thyroid and Pendred’s syndrome) and different...
