Triple-X syndrome as a cause of primary ovarian insufficiency

Cidade-Rodrigues Catarina , Chaves Catarina , Martinho Mariana , Cunha Filipe , Almeida Margarida

IntroductionPrimary ovarian insufficiency (POI) occurs in 1% of women between puberty and 40 years old. Despite being idiopathic in 74–90% of the cases, there are other etiologies, such as genetic causes (in up to 16% of cases). Triple-X syndrome (TXS) is a common (estimated incidence of 1/1000 women) but frequently undiagnosed chromosomal abnormality. Most women are phenotypically normal, despite this fact, POI can still develop. We present a case ...

Is there a role of measuring preoperative serum thyroglobulin?

Rita Elvas Ana , Marques Bernardo , Couto Joana , Raquel G. Martins , Santos Jacinta , Martins Teresa , Rodrigues Fernando

IntroductionThe measurement of serum thyroglobulin (Tg), a glycoprotein produced exclusively by follicular thyroid cells, is an important tumour marker used in the follow-up of patients with differentiated thyroid carcinoma (DTC) and residual or recurrent disease. However, its role as a screening tool before thyroid surgery is not yet defined, as benign conditions can result in its increase.ObjectiveThe aim o...

Predictors of bethesda i category in thyroid fine needle aspiration cytology

Rodrigues Catarina , Benido Silva Vania , Puga Francisca , Freitas Claudia , Couto Carvalho Andre

Introduction: Fine needle aspiration cytology(FNAC) is the mainstay for evaluation of nodular thyroid disease. Internationally reported prevalence for Bethesda I(unsatisfactory sample) category is 5-60%. Several factors may determine this result, including patient and nodules’ features as well as both FNAC performer and pathologists’ skills. Few studies have evaluated pre-procedure factors associated with unsatisfactory cytology results. If present, recognizing these...

Effectiveness of lenvatinib in progressive metastatic radioiodine refractory well differentiated and poorly differentiated thyroid carcinoma

Nunes da Silva Tiago , Regala Catarina , Rodrigues Ricardo , Roque Joao , Damasio Ines , Cavaco Branca , Leite Valeriano

Introduction and objectives: Lenvatinib is the first line treatment for advanced radioiodine refractory (RAIR) differentiated thyroid carcinoma (DTC). Poorly differentiated thyroid carcinoma (PDTC) outcomes with Lenvatinib have only been subjected to sub analysis in one PHASE III study (SELECT), which might limit its real-world use in PDTC. We intend to compare the effectiveness of Lenvatinib in metastatic RAIR DTC and PDTC patients.Methods: Retrospectiv...

PDE4 inhibition attenuates non-alcoholic fatty liver disease by increasing vldl secretion in obese animals

da Silva Hellen , Amelia Montenegro Maria , Gebenlian Juliana , Antunes Rodrigues Jose , de Paula Francisco , Elias Lucila

Non-alcoholic fatty liver disease (NAFLD) is characterized by the pathological increase of lipid droplets, altered fat metabolism in hepatocytes and increased inflammation. Phosphodiesterase 4 (PDE4) modulates the inflammatory responses and its inhibitor can strongly reduce TNF-α release and inflammation. Additionally, PDE4 knockout mice were shown to be resistant to diet-induced obesity (DIO). The aim of this study was to investigate the role of pharmacological PDE4 inhi...

Presurgical lactate dehydrogenase (LDH) levels: A risk factor for disease progression in operated adrenocortical carcinomas

Carreira Ana , Guiomar Joana , Festas Diana , Catarino Diana , Rodrigues Dircea , Moreno Carolina , Melo Miguel , Paiva Isabel

Introduction: Adrenocortical carcinoma (ACC) is a rare malignancy with high recurrence and poor prognosis. Lactate dehydrogenase (LDH) is an enzyme of the glycolytic pathway that is associated with tumour progression in several cancers. To date, evidence on the prognostic value of LDH in ACC is limited.Aims: To assess the impact of LDH in disease-free survival (DFS) in operated ACC.Materials and methods: Retrospective cohort study ...

Characterization of a series of 661 papillary throid microcarcinoma with excellent response to treatment

Rodrigues Elisabete , Silva Paulo , Magalhaes Joao , Pinto Mafalda , Pimenta Tiago , Sobrinho-Simoes Manuel , Soares Paula

Introduction: The management of small size (≤ 1 cm) papillary thyroid carcinoma, also known as papillary thyroid microcarcinoma (PTMC) is a debated topic as it includes tumors with a wide range of biological characteristics and behavior.Objectives: To describe prevalence, clinical and histological characteristics of PTMC with excellent response to treatment after a median follow up of 9.85±6.21 years.Methods: We did a re...

A novel lipoprotein lipase mutation in familial chylomicronemia syndrome – two case reports

Moreno Telma , Ribeiro Sara , Freixo Joao , Pinhao Silvia , Correia Flora , Rodrigues Elisabete

Introduction: Familial chylomicronemia syndrome (FCS) is a rare inherited disorder of lipoprotein metabolism leading to severe hypertriglyceridemia and increased risk for acute pancreatitis. Mutations in the lipoprotein lipase (LPL) gene account for the majority of cases of monogenic chylomicronemia.Methods: We report the cases of two white males with a novel homozygous mutation in position 332 of the LPL gene.Res...

Sotos syndrome in two generations - a reminder that high suspicion is needed in milder phenotypes

Ponte Maria , Pataco Andreia , Medeiros Regina , Luisa Rodrigues Ana , Anselmo Joao

Introduction: The differential diagnosis of overgrowth includes constitutional tall stature, excess growth hormone (GH) and genetic syndromes. Sotos syndrome generally presents with overgrowth, dysmorphisms and early learning disabilities. Here in, we describe the diagnostic pathway of Sotos Syndrome in an adult male presenting with tall stature and mild morphological and cognitive features, prompted by his son’s clear manifestation of the classic triad.<p class="abst...

Hypoglycemia and impared hypoglycemia awareness: frequency and relevance in type 1 diabetes under continuous subcutaneous insulin infusion

Mafalda , Carreira Ana , Vieira Ines , Barros Luisa , Melo Miguel , Rodrigues Dircea , Oliveira Patricia , Baptista Carla , Moreno Carolina , Paiva Isabel

Introduction: Continuous subcutaneous insulin infusion (CSII) therapy in type 1 diabetes (T1D) reduces the risk of hypoglycemia. Hypoglycemia remains a treatment-limiting factor. Impared hypoglycemia awareness (IHA) occurs in 25% of T1D cases and seems to be underestimated by continuous glucose monitoring (CGM). Glycemic variability (GV) is a increasingly valued parameter as a predictor of hypoglycemia and risk of chronic complications.Objective: Analysi...
