Background: The effect of maternal weight gain in obstetric and perinatal morbidity in pregnant with gestational diabetes (GD) is not established.Objectives: Evaluation of the impact of weight gain in obstetric and perinatal outcomes in women with GD.Methods: Retrospective study of women with GD between January/2020-March/2021. Weight gain in pregnancy was evaluated by 2009 IOM recommendations, women were divided in 3 groups: exces...

Introduction: Hirsutism is the presence of terminal hair growth in females with a male distribution pattern. It affects 5-15% of women, being an important sign of androgen excess. The main causes of hirsutism are polycystic ovary syndrome (PCOS) and idiopathic hyperandrogenism. Other significant but less frequent causes of hirsutism include nonclassic congenital adrenal hyperplasia (NCAH), androgen-secreting tumors, and Cushing’s syndrome.Case repor...

Introduction: Primary hyperparathyroidism (PHPT) is characterized by parathyroid hormone (PTH) overproduction, causing hypercalcemia. The most common cause is a parathyroid adenoma. PHPT most frequently presents as asymptomatic hypercalcemia or with nonspecific symptoms. Less frequently, it presents with the classical manifestations of bone disease and nephrolithiasis. Acute pancreatitis (AP) as the initial manifestation of PHPT has been reported rarely. Hypercalcemia can caus...

Introduction: Primary thyroid lymphomas (PTL) account for 5% of all thyroid malignancies. Treatment and prognosis depend on tumor subtype. Contrasting with diffuse large B-cell lymphomas (DLBCL), that have an aggressive clinical course and higher maximum standardized uptake value (SUVmax) in Fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET), thyroid extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) usually show an indolen...

Introduction: Bilateral inferior petrosal sinus sampling (BIPSS) is the gold-standard for the differential diagnosis of ACTH-dependent Cushing Syndrome when the pituitary adenoma on MRI is doubtful or absent. This study aimed to analyze whether BIPSS can influence the outcome in patients with Cushing disease (CD).Methods: Retrospective, descriptive study. Forty-two patients with CD submitted to transsphenoidal surgery (TS) between 2005 and 2016 were divi...

Introduction: Successful long-term management of patients with Cushing’s disease (CD) remains a challenge. Few studies have analyzed the long-term recurrence rates of CD after transsphenoidal surgery (TS).Objectives: 1) to compare the outcome of patients with and without postoperative criteria for cure; 2) to compare the outcome of patients with and without a histological diagnosis of adenoma.Methods: Retrospective, descriptiv...

Introduction: The Sodium Iodide Symporter (NIS) is responsible for active transport of iodide into thyroid follicular cells, enabling the use of radioactive iodine (RAI) for treatment of metastatic disease. Still, a significant proportion of patients with advanced forms of thyroid cancer (TC) became refractory to RAI therapy. Defective NIS expression is the main reason for impaired iodide uptake in TC and NIS downregulation has been associated with several pathways linked to m...

Introduction: Von Hippel-Lindau disease (VHLD) is a rare autosomal-dominant syndrome, characterized by the development of multiple cysts and tumours, namely retinal and central nervous system hemangioblastomas, renal cell carcinoma (RCC), phaeochromocytoma, pancreatic endocrine tumours (PET) and endolymphatic sac tumours.Most germinal mutations are missense, related to a high risk for presenting phaechromocytoma (specially if Arg167Trp mutation im...

Background and aims: It is known that unilateral adrenalectomy as treatment for autonomous secreting adrenal cortex adenomas effectively reduces cardiometabolic risk. Non-autonomous secreting adenomas are not expected to increase cardiometabolic risk, but this has not been thoroughly explored.We evaluated the blood pressure and glycemic profile before and after unilateral adrenalectomy for both autonomous and non-autonomous secreting adrenal cortex adenomas.<p class="abste...

Introduction: The use of Continuous Subcutaneous Insulin Infusion (CSII) is expected to improve glycemic control and to reduce hypoglycemia events. However, long-term beneficial results in glucose control are not always observed. We evaluated long-time glucose control and severe hypoglycemias in type 1 diabetic patients using CSII, without continuous glucose monitoring.Patients and methods: This was a retrospective study of adult type 1 diabetic patients...
