Background: Gastric and duodenal neuroendocrine tumours are increasing in incidence. ENETS guidelines suggest endoscopic resection of type 1 gastric NENs over 10 mm and consider endoscopic resection for duodenal NENs. However, the endoscopic techniques are not clearly mandated. There, is evidence to suggest endoscopic mucosal dissection has higher incidence of R0 resections compared with polypectomy or EMR alone. We have reviewed our data of endoscopic resection of gastro-duod...

Many organs are functionally sexually dimorphic, resulting in profound differences in the activity of several physiological systems, including the hypothalamic-pituitary-adrenal (HPA) axis. The rodent HPA axis matures post-weaning, characterized by parallel increments in adrenal weight, adrenal cortical size and corticosterone secretion. Between postnatal days (PND) 30 to 45, these parameters increase to a greater extent in females compared to males. Over this same interval, h...

Background: Association of differentiated thyroid carcinoma (DTC) and cortisol-producing adrenal adenoma is not part of the classical MEN syndromes. We present a clinical case raising the question of a common etiology for these tumours.Case Presentation: A 58-year-old female presented in 2010 for the investigation of a 6 cm left adrenal tumour incidentally discovered by abdominal CT. Medical history included smoking, obesity, myocardial infarction, hyper...

Background: Aggressive prolactinomas are rare neoplasms that are characterized by rapid growth and usually large tumor size, invasion of adjacent structures, an aggressive clinical behavior with little response to conventional treatment, high rate of recurrence, and elevated morbidity and mortality.Case Report: 48-year-old woman diagnosed with life-threatening aggressive prolactinoma was referred to us for evaluation of complementary therapy after therap...

Background: Secondary adrenal insufficiency is usually treated with hydrocortisone replacement therapy twice or thrice daily in varying doses to mimic the physiological rhythm of cortisol release. However, despite efforts to optimize treatment regimens patients report impaired quality of life (QoL), including important aspects such as fatigue. A possible explanation is a suboptimal imitation of cortisol release resulting in an inadequate substitution at certain times during th...

Introduction: Hyperglycaemia occurs frequently in catecholamine-secreting tumours due to insulin suppression or induced insulin resistance. These changes can be reversible postoperatory (postOp).Objective: Our study aims to establish the impact of surgery in patients with catecholamine-secreting tumours upon glucose metabolism disorders, as well as the predictive factors for postOp diabetes-free patients.Methods: We retrospectively...

Objective: To investigate adherence to hormone replacement therapy (HRT) in patients with hypopituitarism in a tertiary center outpatient clinic.Patients and methods: Prospective, cross-sectional study of patients with hypopituitarism on HRT for at least two pituitary deficiencies (independent of diabetes insipidus). Medication adherence was assessed using a validated Portuguese version of four-item Morisky scale, in which participants were asked to indi...

Somatostatin analogues (SSA) are the mainstay of pituitary-targeted pharmacological treatment in acromegaly, but are characterized by high incidence of resistance in half of cases. The successful management of acromegaly involves in addition to targeting biochemical control the treatment of the metabolic comorbidities and hypopituitarism. In this study we analysed the impact of the concomitant antidiabetic treatment and hormone replacement on the response to SSA. Data were col...

Introduction: Graves’ orbitopathy is usually associated with Graves’ Disease, which is typically characterized by hyperthyroidism and goiter. However, in rare situations, Graves’ disease can also present with hypothyroidism and orbitopathy.Case report: Male, 38 years old, followed by his ophthalmologist for thyroid orbitopathy (exophthalmos right>left and conjunctival hyperaemia since 1 year ago) associated with asthenia, tiredness and...

Seventy percent of women bearing PCOS are obese; adiponectin and TNFα, as obesity markers, have a dual role in the sensitivity and action of insulin. Adiponectin (insulin sensitising) decreases, whereas, TNFα, IL6 (negative regulators of insulin pathway) increases in obese-women. Moreover, TNFα decreases the transcript and protein levels of adiponectin. These changes could affect the normal energetic status in endometrium, tissue that exhibits abnormal insulin s...
