Introduction: The simultaneous occurrence of two drug-induced thyroid dysfunctions is rare. We present a case of central hypothyroidism due to bexarotene (BXC), followed by Interferon-α (IFNα)-induced Graves’ disease (GD) thyrotoxicosis after 2 years.Case Report: A 56-year-old man with no prior thyroid disease was diagnosed with cutaneous T-cell lymphoma and commenced treatment with BXC 600 mg/day and IFNα 90 mg/week concurrently. Aft...

Background: The detection of thyroid incidental uptake of radiopharmaceuticals has been increasing. Those detected by 18F-fluorodeoxyglucose positron emission tomography (PET) have been associated with a significant risk of malignancy (8–64%). Gallium-68 (Ga-68) labelled peptides are now the standard imaging modality for staging neuroendocrine tumours (NET). Its high sensitivity has increased the discovery of incidental findings. The aim of this study was to ev...

Background and aims: The value of the revised (2009) UICC/TNM criteria for medullary thyroid cancer (MTC) is not established. We aimed to evaluate its predictive value, analyzing the consequences of the inclusion of T3N0M0 patients previously included in stage III of the 6th edition, in stage II of the 7th.Patients and methods: We retrospectively analysed the clinical records of 85 patients operated for MTC and followed in two tertiary hospitals in the c...

Currently there is no widely accepted definition of very low-risk papillary thyroid carcinoma (PTC). Although unifocal microcarcinomas without extrathyroidal extension and no local or distant metastases have been recognized as having an excellent overall prognosis the threshold for such a favourable clinical behaviour remains controversial. The study aim was to identify the clinicopathological characteristics of T1 tumours (≤2 cm) presenting a very low-risk of mortality ...

Introduction: Pheochromocytoma (Pheo) and paragangliomas (PGL) are rare catecholamine-producing tumors.Near 35% of patients have disease-causing germline mutations.10% are malignant although the malignancy rate differs accordingly to the genetic background.Purpose: This study aims to characterize the sample of patients followed on a tertiary Portuguese Center and associate the presence of genetic mutation with clinical presentation.<p class="abstext"...

Introduction: Sex steroid hormones play a key role in bone health, however medical therapies for gender dysphoria lead to hormonal changes.Purpose: Understanding the change in bone mass and body composition is extremely important, because this treatment will be carried out over a long period of timeMethods: In a prospective study, we included 19 transgender men (female-to-male trans persons) before treatment and after 1 year of tre...

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...

Background: A systematic literature review (SLR) was conducted to assess the use of independent injections (self/partner/home-administered) as an alternative to healthcare-setting injections for chronic diseases. The primary objective was to identify studies reporting on independent injection of somatostatin analogues (SSAs). Comparative evidence on independent injection of other medications was examined as a secondary objective.Methods: MEDLINE/Embase/t...

Background: Acromegaly is a rare disorder characterized by excess growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Extended dosing intervals (EDIs) of pharmacological treatments may reduce patient burden and costs compared with standard dosing. This systematic literature review (SLR) investigated treatment of acromegaly at EDIs.Methods: MEDLINE/Embase/the Cochrane Library (2001–June 2021) and key congresses (2018–2021) were searche...

Background: We recently have shown a close association of high concentrations of soluble alpha klotho (sαKL) to disease activity in acromegaly. Small pilot studies suggested that sαKL concentrations might be reduced in GH deficiency (GHD) and increase after recombinant human GH (rhGH) therapy. Our aim was to evaluate the potential of sαKL as a biomarker in GHD.Methods: We evaluated sαKL in comparison to the classical biomarkers GH, IG...
