Introduction: Immune checkpoint inhibitors (ICPIs) are recent approved drugs used in malignant melanoma, non-small-cell lung cancer and renal cell cancer. They act by activating host T cell against malignant antigens. Immune checkpoint blockade can lead to breaking of immune self-tolerance, thereby inducing autoimmune/autoinflammatory side effects, such as endocrinopathies. It may affect thyroid, adrenal and pituitary. We present two ICPIs induced thyroiditis cases.<p clas...

Introduction: Hodgkin lymphoma (HL) survivors may develop a range of long-term complications that arise years after therapy. Among these, the endocrine dysfunctions are a major concern. Aim: To investigate the long-term endocrine effects of HL treatment.Methods: Revision of the HL patients’ medical files who were followed at our Endocrine Late-effects Clinics.Results: We studied 178 patients (86 (48.3%) were female), whose mea...

Context: Many pediatric cancer survivors have endocrine conditions. After alkylating agents, steroids, methotrexate and radiation, several endocrine dysfunctions may appear. Surveillance for late effects is recommended by worldwide guidelines.Objective: The objective of the study was to describe the endocrine outcomes of 764 patients followed during a 20 years period in our out-patient clinic.Design: The design was a retrospective ...

Introduction: Chemotherapy may be an important cause of primary infertility, especially in girls submitted to this therapy at very young ages.Clinical case: A 20-year-old female was diagnosed with acute lymphoblastic leukaemia at the age of 1. She was submitted to chemotherapy: intrathecal methotrexate and cyclophosphamide and i.v. doxorubicin, vincristine, mercaptopurine, asparaginase and bone marrow transplantation at the age of 2. She was ref...

Introduction: LDL cholesterol (LDL-C) is a major risk factor for atherosclerosis. The Friedewald formula (FF) is limited by hypertriglyceridaemia. We aimed to correlate serum LDL-C measured by direct assay with serum LDL-C estimated by several formulas: Friedewald (FF): LDL-C=CT-HDL−TG/5; Tsai (TsaiF): LDL-C=TC-HDL−TG/8 (TG/8 represents very-LDL-C); DeLong (DeLongF): LDL-C=TC-HDL−TG×0.16 and Chen (ChenF): LDL-C=non-HDL-cholesterol×0.9−TG×...

Introduction: Thyrotoxicosis after total thyroidectomy (TT) is mostly iatrogenic. Rarely, an hyperfunctional thyroid remnant or ectopic tissue may be the cause. We report a case of Graves’s disease in a mediastinal thyroid mass presenting 7 years after TT for nontoxic goitre.Case report: A 67-year-old woman presented with palpitations, fatigue and weight loss. She had a history of TT for nontoxic multinodular goitre at the age of 60 without any sign...

Background: Takotsubo cardiomyopathy (TC) is characterised by acute, transient left ventricular apical ballooning precipitated by emotional or physiologically stressful stimuli and has been previously associated with Graves’ disease based on few clinical reports. More recently, the association with exogenous thyrotoxicosis and radioiodine-induced thyroiditis has also been described. Iatrogenic hyperthyroidism on patients under levothyroxine replacement therapy for hypothy...

Introduction: Children undergoing treatment for cancer are prone to several long-term endocrine complications, which can permanently affect bone tissue.Case report: A 25-year-old man was diagnosed with right maxillary sinus rhabdomyosarcoma at the age of 5. He was submitted to chemotherapy – intrathecal methotrexate+prednisolone and i.v. vincristine+actinomycin+ifosfamide – and submaxillary+cervical radiotherapy, 60Gy. At the age of 12, he was ...

Background and aims: Maternal BMI and weight gain are associated with maternal and fetal complications in gestational diabetes (GD), but their relative contribution is not clearly defined. Our aim was to determine the influence of BMI and weight gain in the evolution of GD.Material and methods: Multicenter, retrospective study of women diagnosed with GD at the medical centers of the Portuguese Group for the Study of Diabetes and Pregnancy in 2011. We use...

Introduction: The increasing risk of thyroid cancer (TC) in patients who underwent radiotherapy is well documented, especially at early ages. In our center, young patients undergoing cancer treatments are referenced to Endocrine Rehabilitation Clinics (ERC). Their risks are initially identified and monitored regularly. We intended to analyze the characteristics and outcomes of patients who developed post-radiotherapy TC.Methods: Medical records of patien...
