Ectopic cushing’s syndrome secondary to acinic cell carcinoma of the parotida gland: A case-report

Pinheiro Sara , Filipe Juliana , Meireles Pedro , Castelo Branco Sara , Rito Miguel , Nunes da Silva Tiago

Background: Ectopic ACTH secretion from metastatic acinic cell carcinoma (ACC) of the parotid gland is extremely rare. ACC is an uncommon, typically indolent, salivary gland neoplasm. Herein, we report a case of a high-grade ACC later diagnosed with Cushing’s syndrome (CS).Case presentation: A 60-year-old man presented with a laterocervical mass. Computed tomography (CT) documented a 39×38 mm mass on the parotid gland and homolateral cervical l...

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...

Epidemiology and treatment of adrenal cancer. a case series

Lewicki Marcin , Zwolak Agnieszka , Świrska Joanna , Gołda Anna , Tywanek Ewa

Introduction: Adrenal cancer is a rare, highly invasive malignant tumour with the incidence estimated for approximately 0,5-2,0 cases per milion people annually. Considering the fact that adrenal cancer is very sporadic not much data on its epidemiology is available.Aim of the study: The aim of the study was to present the single-center data on the epidemiology of the adrenal cancer.Material and methods: Patients with the diagnosis...

Cyclic cushing’s syndrome: understanding the patterns of a complex endocrine disorder

Tavares da Silva Beatriz , Martins Fernandes Andreia , Almeida Raquel , Teresa Pereira Maria , Amaral Claudia

Introduction: Cyclic Cushing’s Syndrome is an uncommon disorder characterized by recurrent episodes of elevated cortisol levels, alternating with periods of normal cortisol secretion. These cycles of hypercortisolism can occur at regular or irregular intervals, ranging from days to years between episodes.Case presentation: A 57-year-old woman evaluated at the Endocrinology Outpatient Clinic because of symptoms of hypercortisolism with 18 months of e...

5β-reductase is downregulated in patients with non-alcoholic fatty liver disease and hepatocellular carcinoma and controls metabolic and proliferative phenotype through LXR-dependent mechanisms

Nikolaou Nikolaos , Arvaniti Anastasia , Sanna Fabio , Saikali Michael , da Conceicao Ismael , Dempster Niall , Gathercole Laura , Cummins Carolyn , Tomlinson Jeremy

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease ranging from simple intrahepatic lipid accumulation to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). 5β-reductase (AKR1D1) is a liver enzyme that catalyses a fundamental step in bile acid (BA) synthesis. Both BAs and BA intermediates are established as potent regulators of metabolic and proliferative phenotype. We have hypothesised that AKR1D1 plays a crucial regulatory role in NAFLD and HCC. Hu...

How would school children design a poster about diabetes, obesity, health technologies and emotional wellbeing awareness?

Narendran Alisha , Anthony Amarah , Kelly Graham , Xavier Gabriela Da Silva , Shahzad Atif , Arlt Wiebke , Gillett Caroline DT , Kempegowda Punith

Introduction: Knowledge about end-user perceptions is important to ensure educational resources have maximal impact.Objective: To understand school children’s perceptions and ideas about three endocrine topics.Methods: This activity was done as part of Society for Endocrinology public engagement grant. Years 5 and 6 school children (aged 10-11 years) from Nonsuch Primary School in Birmingham were invited to create posters on t...

Dysregulation of cytochrome P450 oxidoreductase (POR) in NAFLD and hepatocellular carcinoma; evidence from clinical, rodent and cellular models

da Conceicao Ismael , Nikolaou Nikolaos , Gathercole Laura , Harris Shelley , Dempster Niall , Moolla Ahmad , Hodson Leanne , Tomlinson Jeremy

The incidence of non-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, continues to rise. NAFLD is associated with significant liver-specific and cardiovascular morbidity and mortality, including hepatocellular carcinoma (HCC). Currently, there are no licensed therapies, highlighting the importance of understanding the pathogenic mechanisms that drive the condition. Cytochrome p450 oxidoreductase (POR) plays an essential role in activa...

A clinical and molecular study of a real-world cohort of braf v600e anaplastic thyroid carcinoma treated with dabrafenib and trametinib

Nunes da Silva Tiago , Rodrigues Ricardo , Rito Miguel , Saramago Ana , Pires Carolina , Horta Mariana , Leite Valeriano , Cavaco Branca

Introduction and objectives: Anaplastic thyroid cancer (ATC) has a very low overall survival (OS) and progression free survival (PFS) due to fast growth and resistance to non-target therapies. A recent phase II study showed a dramatic increase in OS and PFS of BRAF V600E mutated ATC patients treated with Dabrafenib and Trametinib (DT). However as commonly reported in melanoma durable responses in ATC may be compromised by resistance mechanisms. Until now only a few ca...

PDE4 Inhibitors Act in The Brain to Ameliorate Metabolic Parameters in Diet-Induced Obesity

da Silva Hellen , Mendonca Duarte Luiza , De Souza Seixas Michele , Antunes Rodrigues Jose , de Paula Francisco , Elias Lucila

Obesity is associated with peripheral and central low grade inflammation characterized by the increase in pro-inflammatory cytokines, such as tumor necrosis factor alpha (TNF). Phosphodiesterase 4 (PDE4) modulates the inflammatory responses and its inhibitor can strongly reduce TNF 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 central and peripheral effec...
