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: Diffuse lipomatosis of the thyroid is a very rare disease, characterized by extensive infiltration of thyroid parenchyma by mature adipose tissue. It is not accompanied by accumulation of amyloid fibrils.Clinical report: Male, 47 years old, followed in Endocrinology by hypothyroidism, since 13 years old, medicated with levothyroxine, with unremarkable growth and pshicomotor development. In 2002, thyroid echography showed a solid and heterog...

Pituitary carcinomas are rare and represent a challenge in clinical practice. Most secondary tumour localizations are intracranial and spinal, followed by liver, cervical lymph node, bone and, rarely, lung. PC frequently exhibit resistance to most usual therapies and the mean survival time is usually <4 years once metastases have been identified. Ectopic ACTH Syndrome is, in up to 50% cases, caused by lung tumours including carcinoids or Small Cell Lung Carcinomas (SCLC). ...

Introduction: Eating habits may contribute to longevity. Consumption of red meat, source of saturated fatty acids and cholesterol may be associated with increased risks of diabetes, cardiovascular disease (CVD), and mortality risk.Methods: We studied 521 subjects, both genders, 253 centenarians (CENT) (100.26±1.98 age) and 268 controls (67.51±3.25 age), both low (LCR) and high cardiovascular risk (HCR), calculated based on QRISK®2-2016. An...

Background: Residual C-peptide (CP) secretion has been associated with better glycemic control in patients with type 1 diabetes (T1D).Aim: To evaluate how residual fasting CP (fCP) secretion impacts glycemic control in T1D and to identify possible confounding factors.Methods: A retrospective analysis of adult patients with T1D followed in our department that had their fCP and glucose levels obtained on the same blood sample during ...

Background: The use of Flash Glucose Monitoring (FGM) for the management of type 1 diabetes mellitus (T1D) is rapidly increasing.Aims: To assess the longitudinal evolution of glycated haemoglobin (HbA1c) and body mass index (BMI) with the use of FGM in patients with T1D; to determine predictive factors of benefit with the use of this technology.Materials and methods: Retrospective study of T1D patients, using FGM ≥6 months an...

Introduction: IgG4-related Hashimoto’s thyroiditis (HT) is a very recently reported entity, characterized by thyroid inflammation rich in IgG4-positive plasma cells associated with marked fibrosis. It may be part of the systemic IgG4-related sclerosing disease and is associated with younger age, lower female:male ratio, higher levels of thyroid autoantibodies, low echogenicity on ultrasound (US), rapid progress requiring surgery and more subclinical hypothyroidism, when c...

IntroductionPheochromocytoma(PHEO) occurs in pregnancy with an estimated incidence of 0.007%. Its rarity and overlapping presentation with other pregnancy-related hypertensive disorders make the diagnosis really challenging. If left unrecognized, may result in increased maternal and fetal mortality. There are no guidelines on approaching PHEO during pregnancy. This case highlights the difficulties encountered in managing this condition in pregnancy.<...
