Introduction: Medullary thyroid cancer (MTC), in its familial forms, is usually associated with pheochromocytoma and primary hyperparathyroidism, related to an underlying germline RET mutation. SDHx germline mutations associated with MTC have not yet been reported.Case report: We report the case of a 60-years-old woman, who was submitted, elsewhere, in November/2013, to a total thyroidectomy+right lymph-node dissection due to a nodule s...

Paragangliomas (PG) originating from the nasal cavity are very rare and usually have an indolent growth. Surgery offers the only possibility of cure for these patients while radiotherapy can only slow their growth rate. Intracranial or leptomeningeal dissemination is very rare, with only 7 cases described in the literature. A 77 year old man with a 4-years history of nasal obstruction. He underwent a nasofibroscopy with a biopsy that revealed a nasosinusal neuroendocrine tumou...

Primary aldosteronism (PA) is generally caused by an adenoma or adrenal hyperplasia. To discern between these two, selective adrenal vein sampling (AVS) is necessary. Adequate interpretation requires that RAAS-interfering medication be withdrawn. We report a patient with severe PA, where it was not possible to safely withdraw RAAS-interfering medication.Case: A 37-year-old male was referred for AVS. He had documented PA and bilateral adrenal adenomas on ...

Until 12th week of gestation foetus is entirely dependent on maternal thyroxine. Inadequate thyroxine replacement may lead to lower IQ of offspring and also an increased miscarriage rate.We audited 68 hypothyroid pregnant females to assess whether management of their thyroid status had met current standards. In the first trimester TSH is not an optimal monitoring marker as it is supressed by rising HCG level. According to established clinical guidelines ...

Background: Following the advent of thyroid function screening and highly sensitive TSH assay subclinical hyperthyroidism (SCHT) is becoming increasingly common. No audit addressed the treatment outcome of this group of patients.Methods: Prospective analysis of management outcome of patients seen in endocrine clinic over 36 months was carried out. 46 patients who presented with SCHT were included, of whom 41 had confirmed SCHT on repeat testing.<p cl...

Introduction: Lipid profile characterization in women with gestational diabetes mellitus (GDM) and its impact on post-partum dysglycemia remains to elucidate. The aim of this study was to evaluate lipid profile in women with GDM during pregnancy and 8 weeks after and to study its correlation with glycemic control.Methods: This study was carried out in a central hospital in Portugal. All women with GDM diagnosed from January/2014 to December/2015 were enr...

Metabolic disorders, such as overweight and obesity, are serious health societal challenges due to their high incidence rates. Obesity leads to metabolic dysregulation, promoting hormonal imbalance, oxidative stress, and a chronic inflammation state. Eating habits towards the intake of highly caloric fat-rich regimes induce epigenetic changes in the information transgenerationally transmitted. Furthermore, obesity promotes carcinogenesis. It is known that the prostate is sensi...

Introduction: The somatotropin deficit is one of the late consequences of cancer treatments. The administration of somatotropin implies treatment with daily injections, which hinders therapeutic adherence. This goal is a challenge for survivors and health professionals. Therapeutic education and new technologies are instruments that favor the training and development of control mechanisms that promote and motivate the behavior’s change.Objective: To...

Introduction: Asparaginase is a component of chemotherapy regimens used to treat paediatric acute lymphoblastic leukaemia (ALL). One of its well-known side effects is hyperglycaemia which is probably related to hypoinsulinemia. Its incidence rises significantly when associated with corticotherapy. We present two cases of diabetes related to asparaginase and corticoid administration.Case 1: Eleven-year-old girl diagnosed with an ALL. Before treatment she ...

Introduction: In our practice we’ve been following some oncologic survivors patients with low-low/normal levels of testosterone who are asymptomatic. Aims: to determine the levels of total (TT) and free testosterones (FT) and dihydrotestosterone (DHT) in healthy men, in order to find the reference intervals (RI) adjusted to our population and compare them with those provided by the kit-producers (KP).Methods: We collected blood samples from 125 heal...
