Molecular variability determines subtle adrenal biosynthetic defect in non-classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency

Mermejo Livia , Coeli-Lacchini Fernanda , Turatti Wendy , Elamid Marcia , Parente Renata , Martinelli Carlos , Antonini Sonir , Castro Margaret , Moreira Ayrton

There is a clinical spectrum of non-classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (NC-CAH). In addition, CYP21A2 gene mutations analysis present in homozygosis or as compound heterozygosis.Objectives: To evaluate the relationship between the genotype and biochemical profiles and also compare with clinical severity in NC-CAH.Patients and methods: Clinical, hormonal and molecular data of 57 patien...

Quality of life in patients with neuroendocrine tumors treated with 177Lu-[DOTA0,Tyr3]-octreotate: a Single Tertiary Care Portuguese Center Experience

Lages Adriana , Moreira Helder , Costa Gracinda , Oliveira Patricia , Oliveira Diana , Martins Diana , Ventura Mara , Cunha Nelson , Carrilho Francisco

Introduction and purpose: 177Lu-[DOTA0,Tyr3]octreotate (177Lu-DOTA-TATE) is a radiopharmaceutical frequently used in peptide receptor radionuclide therapy (PRRT), which is a promising treatment modality in patients with metastasized neuroendocrine tumors (NETs). We purpose to evaluate the quality of life (QoL) in patients with somatostatin receptor positive inoperable or metastatic NETs throughout the three cycle’s (with three months intervals) proto...

Leptin modulates Sertoli cells mitochondrial function and biogenesis with implications for the nutritional support of spermatogenesis

Moreira Bruno M , D Martins Ana , Monteiro Mariana P , Sousa Mario , Alves Marco G , Oliveira Pedro F

Current lifestyle, characterized by physical inactivity and a poor diet, is heavily linked with an increased incidence of metabolic diseases. One of the most serious silent co-morbidities of those diseases is infertility. The hormonal link between food intake and energy homeostasis is mediated by the leptin ghrelin axis. Compelling evidence suggests that direct leptin’s action regulates cellular glucose homeostasis and mitochondrial biogenesis. We have recently shown that...

Early renin recovery after adrenalectomy in patients with aldosterone-producing adenoma - a longitudinal study.

Mermejo Livia M , Elias Paula CL , Molina Carlos AF , Tucci Silvio , Antonini Sonir R , Castro Margaret , Moreira Ayrton

Background: Low plasma aldosterone after adrenalectomy due to aldosterone-producing adenoma (APA) and postoperative hypoaldosteronism recovery have been well described. However, prospective time course comparing simultaneously aldosterone and renin levels is still lacking.Aim: We prospectively studied clinical and biochemical findings emphasizing aldosterone and renin levels, in a cohort of patients with APA who underwent adrenalectomy in a single tertia...

Predictive factors for postoperative hypoparathyroidism after total thyroidectomy

Santos Tiago , André Carvalho , Cláudia Freitas , Raquel da Inez Correia , Costa Moreira da , Cardoso Maria Helena

IntroductionHypoparathyroidism (hypoPT) is one of the most complications after thyroid surgery, usually as transient hypocalcemia. Permanent hypoPT due to permanent parathyoid lesion, despite being less frequent, is associated to long term consequences for both objective and subjective well-being and should be prevented. Identifying predictive factors associated with post- thyroidectomy hypoPT is thereby crucial.Aim<p class="ab...

Thyroid function in heart failure with preserved ejection fraction (HFpEF) – evaluation of serum and myocardial thyroid hormones in an animal model of HFpEF

Sergio Neves Joao , Vale Catarina , Almeida-Coelho Joao , Barez-Lopez Soledad , Jesus Obregon Maria , Isabel Oliveira Ana , Lourenco Andre , Falcao-Pires Ines , Carvalho Davide , Leite-Moreira Adelino

Introduction: Thyroid hormones play a central role in the regulation of the cardiovascular system. Heart failure with preserved ejection fraction (HFpEF) is responsible for more than 50% of all heart failure cases and its main pathophysiological alteration is diastolic dysfunction. Diminished thyroid function is known to predominantly impair diastolic function, however the thyroid hormone status in HFpEF remains largely unknown.Methods: We evaluated an a...

Trends in papillary microcarcinoma prevalence in North of Portugal

Pereira Teresa Alves , Amado Ana , Gouveia Patricia , Castro Rosa , da Costa Antonio Moreira , de Carvalho Andre Couto , Freitas Claudia , Borges Fatima

Introduction and Objectives: The incidence of thyroid cancer has increased worldwide. This increase has been attributed to more diagnosed papillary thyroid microcarcinomas. The purpose of this study was to analyse the growing trend of first appointments in our Thyroid Cancer Unit, namely patients with papillary microcarcinomas.Methods: We performed a retrospective study based on the patients diagnosed with thyroid cancer between 1960 and 2016. We divided...

Adrenocortical carcinoma - casuistic analysis

Ribeiro Catia , Lobo Joao , Mesquita Ana , Martins Pedro C , Peyroteo Mariana , Matos Maria Joao , Antunes Pedro , Sanches Cristina , Moreira Augusto , de Sousa Joaquim Abreu

Introduction: Adrenocortical carcinomas are rare neoplasms with an incidence of 0.7 to 1.5 per million/year. Diagnosis often requires a multidisciplinary approach. When the disease is confined to the adrenal gland, absolute criteria defining malignancy, do not exist, however a score of Weiss> or =a 3 is considered diagnosis. The prognosis is usually reserved and conventional chemotherapy is not curative.Material and Methods: Retrospective analysis of...

Continuous glucose monitoring in glycogen storage disease type Ia – a major improvement for patients

Martins Diana , Oliveira Diana , Baptista Carla , Paiva Sandra , Vicente Nuno , Cardoso Luis , Lages Adriana , Ventura Mara , Cunha Nelson , Moreira Sonia , Clemente Hugo , Esperto Helder , Carrilho Francisco

Introduction: Glycogen storage disease (GSD) type Ia (von Gierke’s disease) is an inherited metabolic disorder of glycogen metabolism, caused by defects in the glucose-6-phosphatase complex, with associated risk of severe hypoglycemia within 3–4 h after a meal.The aim of the present study was to evaluate the efficacy of continuous glucose monitoring (CGM) system in determining the magnitude of hypoglycemia in patients with GSD type Ia.<p cl...

Isolated bone metastases: a rare form of presentation of papillary thyroid carcinoma

Peyroteo Mariana , Ribeiro Catia , Martins Pedro C , Ferreira Ana , Giesteira Laurinda , Barbosa Rui , Carvalho Machado , Ramalho Antonio , Moreira Augusto , de Sousa Abreu

Background: Papillary thyroid cancer (PTC) is the most frequent type of well-differentiated thyroid cancer (WDTC) and frequently poses a management dilemma. Its indolent behavior associated with high long term survival support the trend towards a more conservative management approach. The authors present a case of isolated bone metastases as the form of presentation of papillary thyroid carcinoma. A 61-year-old man was admitted with complaints of lower back pain for the previo...
