We have shown that repeated cold stress increases ovarian sympathetic tonus and induces typical polycystic ovary syndrome (PCOS) features. Lesion of the noradrenergic nucleus Locus Coeruleus decreases ovarian noradrenaline release and prevents stress-induced PCOS in rats exposed to chronic intermittent cold stress. The aim of this study was to assess whether the alterations on ovarian morphology, ovulation rate and hormonal secretion induced by cold stress could be prevented b...

IntroductionPituitary apoplexy (PA) consists of acute infarction/hemorrhage of the gland, involving mostly a previously unrecognized adenoma. One of its most documented precipitating factors is anticoagulation in the context of acute coronary syndrome treatment. To our knowledge only one report described a PA secondary to anticoagulation for pulmonary thromboembolism.Case reportA 75-year-old men with known hy...

IntroductionThe malignancy risk of an adrenal nodule is based on clinical symptoms (rapid onset of hypercortisolism and hyperandrogenism; mass symptoms) and imaging characteristics. These suspicious criteria include boundary irregularities, heterogeneity, dimension>6 cm and density>20 HU (CT). However, these are not absolute criteria.Case reportWe report the case of a 43 years-old female patient with a histor...

Introduction: The treatment of Primary Adrenal Insufficiency involves the chronic use of glucocorticoids. The balance between the dose needed to supply the cortisol deficit and the possible consequences of overtreatment is a challenge. In patients with Addison disease (AD), androgens deficiency is an additional factor for osteoporosis.Objective: To evaluate if there are differences in bone mineral density (BMD) in patients with Addison’s disease ver...

Introduction: The effects of long-term replacement therapy of primary adrenal insufficiency (PAI) are still a matter of debate. Glucocorticoid (GC) replacement regimens do not completely mimic the endogenous hormonal production and their monitoring is sometimes difficult. Therefore, some patients are exposed to mild GC excess with potential complications, such as hypertension, diabetes, and skeletal fragility. Data on bone mineral density (BMD) in PAI is still scarce and contr...

Introduction: Hypopituitarism is a rare entity that can have different aetiologies. Symptoms are usually progressive and non-specific; therefore, many patients are underdiagnosed and untreated. We present a clinical case of a patient presenting septic shock, hyponatremia and central hypothyroidism.Case report: A 46-year-old man was admitted in ICU for septic shock of unknown origin and multiorgan failure. Hormonal profile showed central hypothyroidism, p...

Introduction: The Dandy-Walker complex (DW) comprises a rare intracranial malformation of the posterior fossa and multiple organ anomalies. The association with endocrine pathology is rare - described in isolated cases (Kallman syndrome, primary hypothyroidism (PH) and central precocious puberty). Noonan syndrome (NS) is a genetic disease usually diagnosed at birth, with variable phenotype. Most cases have AD transmission, with the PTPN11 gene mutation responsible for 50%....

Although, diabetes type I patients in Portugal have complete and free access to HbA1c management (via multiple daily injections) only a few percentage has been provided an insulin pump – priority is given to children and women in fertile age trying to get pregnant. By the end of 2014, 1.150 insulin pumps had already been provided by the National Program of Insulin Pumps, but at least 3.000 patients with indication for insulin pump use were in waiting list. HbA1c pre-pump ...

Introduction: Continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI) are forms of intensified insulin therapy and the most used regimens for type 1 diabetes (T1D). Owing to its continuous basal output, hypoglycaemic events tend to be rarer with CSII. Our goal was to evaluate the differences in nocturnal hypoglycemia between these two treatment strategies.Methods: Retrospective analysis of 61 patients who had performed continu...

Introduction: Gynecomastia is a frequent reason for endocrinology consultation and its correct investigation is pivotal towards a precise diagnosis. We present a clinical case of a rare cause of gynecomastia.Case report: A 56-year-old male was referred to the hospital setting for an endocrinology consultation. He noticed increased breast size for a year, initially tender to palpation, and unquantified weight loss. Neither galactorrhea, nor any nipple dis...
