Objective: Evidence shows type 1 diabetes leads to vascular damage and neuropathy. The purpose of this study was to perform a systematic review and a meta-analysis to asses the evidence of the effects of type 1 diabetes on hearing function.Methods: Three different electronic databases were used to identify eligible studies including a manual searching of references. The articles obtained were independently reviewed by two authors using predefined inclusi...

Case: A 46-year-old woman presented to the gynaecology department with secondary amenorrhoea, hirsutism and acne. At the age of 25, she was diagnosed with Von Hippel–Lindau disease (VHLD) on the basis of multiple right retinal haemangioblastomas. Investigation revealed an elevated testosterone 13.4 nmol/l (0.3–2.6 nmol/l), 17 hydroxyprogesterone 18 nmol/l and free androgen index 53.6 (0.0–7.5). A solid lesion in the left ovary was demonstrated on ultrasound scan...

Introduction: Type 1 autoimmune polyglandular syndrome is a rare entity, presenting typically during childhood and comprising a variable combination of autoimmune endocrine and non-endocrine diseases that differ in their immunological features. This phenotypical heterogeneity may difficult the identification of this syndrome.Clinical case: 33 year-old female, presenting with secondary amenorrhoea at the age of 13, and by that date diagnosed with hypergon...

Introduction: Cyclic Cushing syndrome (CCS) involves rhythmic fluctuations in ACTH secretion resulting in a cyclic variation of adrenal steroid production.Case presentation: A 37-year-old woman was referred to our Pituitary Clinic in 1999, for evaluation of galactorrhea and irregular menses that had started four months ago. She also complained of depression, facial hirsutism, alopecia and progressive obesity. Blood pressure was normal. Endocrinological e...

Introduction: There are limited data on the incidence and prevalence of pituitary adenomas (PA). Although classically considered rare, systematic assessments from autopsy and radiological studies have shown a prevalence of 17% in the general population.Objective: We describe the epidemiologic of PA in Braga, the third most populous district of Portugal (860 000 inhabitants, 2673 km2), over the last 20 years.Methods: We r...

Introduction: Adrenal surgical series are scarce in the literature. We aim to present a single institution consecutive case series and to establish a radiologic-pathological correlation.Material and methods: A retrospective, observational and descriptive study was conducted by searching the Pathology database for surgically removed adrenal lesions. Cases were matched with the Imagiology database. Ultrasound, CT and MRI images were then reviewed by the sa...

Proton nuclear magnetic resonance spectroscopy (1H-NMR) was applied to investigate metabolic profile of type 2 diabetes mellitus (T2DM) patients and identify possible disorders of T2DM.We investigate the potential relationship between diabetic retinopathy (DR), diabetic neuropathy (DN), estimated glomerular filtration rate (eGFR), anthropometric indicators (body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), waist to sta...

Introduction: Graves’ disease is an autoimmune condition with an estimated prevalence of about 2%, 5–10 times more frequent in females. A multifactorial nature is assumed, with genetic contribution accounting for up to 80% of the variability. Relevant genes includegeneral autoimmune risk loci, such as the HLA region, CTLA-4, PTPN22 and CD40, as well as thyroid-specific loci (thyroglobulin and TSH receptor genes). We report a particular case of Graves’ d...

Giant prolactinomas are uncommon, with some individual case reports described in the literature, but with few series documenting treatment outcomes. They represent a therapeutic challenge, since restoring normoprolactinemia, eugonadism and reducing tumour size may not be realistic goals. Specific complications may also arise during treatment that change the initial management plans. The authors describe a case of a 28-year-old male with visual impairment and behavioural change...

Introduction: Prolactinomas are the most common pituitary adenomas in paediatric patients, except in the first decade of life, when ACTH secreting adenomas are more frequent.Objective: Analysis of clinical, diagnostic and therapeutic data of prolactinomas in paediatric age.Methods: Retrospective study of 15 patients whose symptoms began before 18 years of age.Results: In girls, secondary amenorrhea (58.3%) an...
