IntroductionRadioiodine whole-body scintigraphy plays an important role in the follow-up of patients with differentiated thyroid carcinoma (DTC), as it is highly accurate in detecting thyroid residues and recurrent disease. Unusual 131-iodine uptake outside the thyroid bed and areas of physiological uptake is strongly suggestive of distant metastasis. However, uncommon uptake may occur and lead to diagnostic errors.Case report<...

Introduction: Graves Disease (GD) is an autoimmune disease, in which CD4+ Th2 cells secrete interleucin-4 (IL-4) and IL-5 and activate antibody production. IL-4 has been considered a therapeutic target for treatment of immune-related diseases, by enhancing and redirecting T and B cell function. Dupilumab, a monoclonal antibody, inhibits IL-4 and IL-13 and is currently used for treatment of atopic dermatitis, nasal polyposis and asthma. There is a single case report of painless...

Background: In 15% of prolactinomas there is dopamine agonist(DA) resistance. The clinical characteristics, the best diagnostic and therapeutic management of these cases have not been established so far.Aim: To characterize patients taking a high dose cabergoline(≥ 3mg/week) and then describe clinical, biochemical and imaging features of cabergoline-resistant cases.Methods: Retrospective study with 5 centers representing the ...

This paper aims to describe the followed population in the consultation, through a retrospective study in a hospital unit. This retrospective study was carried out during February 2020 to February 2022, and analyses the clinical processes of the patients that were followed in this consultation, and later analysing the data using Microsoft Excel® Over these two years, 395 patients were observed. These patients age average 61 years old, ranging from 17 to 93 years of age. M...

Introduction: Tumour microenvironment (TME) is determined by non-tumoral cells, including immune, stromal or endothelial cells, and influences tumorigenesis, proliferation, invasiveness and angiogenesis. Little is known about TME in pituitary adenomas (PAs). We aimed to characterise the TME of PAs and its role in their aggressiveness, focusing on PA-infiltrating immune cells and cytokine network.Methods: Cytokine secretome from 24 human PAs (16NFPAs, 8GH...

Background: The diagnosis of Cushing’s syndrome (CS) remains a challenge in clinical endocrinology. Several screening tests have been proposed to establish hypercortisolism. Late-night salivary cortisol (LNSC) is used as screening tool, however, individualized cut-off levels for each population must be defined.Methods: Three group of subjects were studied: healthy volunteers, suspected CS and proven CS. All patients collected saliva at 23.00 h using...

Introduction: Although inpatients hyperglycemia is a current uneasiness among the medical community, its prevalence in Portugal in unknown. We aim to identify ‘Stress hyperglycemia’ and ‘New onset diabetes’ cases in inpatients in a district hospital.Methods: We evaluated inpatients from Internal Medicine (IM), General Surgery (GS), Orthopedics and Traumatology (OT) and Stoke Unit (SU) departments, admitted from the emergency departmen...

Introduction: Thyroglobulin (Tg) measurement in needle washouts from fine-needle aspiration biopsies (FNA-Tg) increases the sensitivity of lymph node (LN) metastasis diagnosis in differentiated thyroid cancer (DTC). However, the cutoff value for FNA-Tg has not been clearly established and there are large differences between clinical studies, which hinders its interpretation. Our study aimed to investigate the optimal cutoff value of FNA-Tg and evaluate its utility in the diagn...

Introduction: Although recognized as a risk factor in most staging systems, including the UICC TNM classification, the significance of microscopic extrathyroid extension (ETE) in papillary thyroid carcinoma (PTC) remains controversial. Despite this fact, its diagnosis by a pathologist following surgery for tumours ≤ 4 cm without metastases means an upstaging to pT3 and stage III in patients over 45 years, implying a poorer survival. Our study aimed to evaluate the impact...

Introduction: The microvascular complications of diabetes and consequent autonomic neuropathy may cause changes in saliva’s secretion and composition. Hyperglycemic levels can also contribute to various oral pathological changes due to alteration of fungi or bacterial flora and dental biofilm surface, leading to the onset of candidiasis, periodontitis and dental caries. The aim of this study was to determine total bacterial load of saliva and dental biofilm of diabetic pa...
