Introduction: Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with poor prognosis. Objective: The aim of this study is to characterize patients with ACC followed at a tertiary center. Material and Methods: Retrospective analysis of clinical records of patients with histopathological diagnosis of ACC followed in our clinic. Results and conclusions: We reviewed 11 patients. The average age at diagnosis was 57.3±15.2 years and 63.6% were females. Seven patients...

Introduction: Milk-alkali syndrome is defined by the triad hypercalcemia, metabolic alkalosis and renal impairment, due to intake of calcium salts and absorbable alkali. It is the 3rd leading cause of hypercalcemia but often underdiagnosed. Patients with chronic hypoparathyroidism after total thyroidectomy have increased risk for this potentially life-threatening complication and its epidemiology is unclear. We present a case of milk-alkali syndrome in a patient with chronic h...

Introduction: Primary hyperparathyroidism (pHPT) is the most common cause of hypercalcemia in the outpatient setting and is a frequent endocrine disorder. Large cohort studies of pHPT patients in the Portuguese population are scarce. Aim: To characterize patients with pHPT followed at a tertiary center.Material and Methods: Retrospective analysis of clinical records of patients with pHPT followed in our hospital from 2003 to 2021. ...

Introduction: Sheehan Syndrome (SS) is a cause of hypopituitarism resulting from postpartum pituitary infarction. Its frequency is decreasing worldwide, particularly in developed countries due to advances in obstetric care. Case report: A 50-year-old female patient was admitted to the emergency department with complains of progressive pain in the lower hemithorax and abdomen. She also referred constipation, weight gain and asthenia. The initial laborator...

The impact of BMI, exercise, smoking, drug and alcohol use on reproductive and thyroid hormones has little or conflicting evidence. We therefore aimed to investigate the association between these factors and serum hormone concentrations. Capillary blood samples were taken from 932 eumenorrheic Hertility Health users on menstrual cycle day 3 between Sept 2020 and June 2022. Serum concentrations of Anti-Müllerian hormone, Estradiol (E2), Luteinising Hormone (LH), Follicle-S...

Introduction: Maternal obesity is associated with an increased risk of gestational diabetes, large for gestational age (LGA) newborns, preterm delivery, congenital malformations, and fetal death. On the other hand, bariatric surgery before pregnancy is associated with a reduction of obesity-associated complications, but also with an increased risk of small for gestational age (SGA) newborns, fetal growth restriction and micronutrient deficiencies during pregnancy.<p class=...

Changes in the composition of the extracellular matrix (ECM) induce different cell signaling in normal tissues and in pathological conditions. ECM alteration in the adrenal microenvironment may contribute to both the development and function of adrenal gland. The adrenal gland consists of a cortex, with three concentric zones, glomerulosa (ZG), fasciculata (ZF) and reticularis (ZR), and the medulla (M), surrounded by a capsule. Here, we describe the differences among the ECM s...

Introduction: Parathyroid carcinoma (PC) is an extremely rare malignancy. A complete surgical excision is often difficult, and persistent/recurrent disease occurs in up to 65% of cases. Progression often leads to symptomatic hypercalcemia, the major contributor to poor quality of life and mortality. Treatment options beyond surgical resection are limited. Denosumab is an approved therapy for refractory hypercalcemia of malignancy, and its use in unresectable PC has been descri...

Obesity incidence is increasing globally at an alarming rate, particularly amongst children and young adults. Male obesity has been linked with a reduction in sperm quality and consequently decreased fertilization rates. Seminal vesicles are considered fundamental for male fertility and though for men’s health. Vesicle seminal secretion contributes to a significant volume of seminal fluid, being extremely important for semen coagulation and sperm motility. Recent studies ...

Background and aims: Obesity is a chronic multifactorial disease characterized by an excessive accumulation of body fat resulting from an imbalance between energy intake and caloric expenditure. Uncoupling protein 2 (UCP2) is located in the inner mitochondrial membrane and plays an important role in the regulation of energy expenditure. NLR family, pyrin domain-containing 3 (NLRP3) inflammasome seems to have a key role in obesity-induced inflammation through production of the ...
