Introduction: Acromegaly is a rare disorder and sporadic cases are the most frequent. It can also occur in association with genetic syndromes, such as Carney complex, multiple endocrine neoplasia type 1 (MEN-1), MEN-1 like syndrome, isolated familial acromegaly and familial isolated pituitary adenomas.Case report: Thirty five -year-old man was observed in 1994 for gynecomastia. Acromegaly was diagnosed based on clinical, biochemical (IGF1 1094.7 ng/ml, b...

Introduction: Corticotroph pituitary adenomas that cause Cushing’s disease (CD) predominantly express the dopamine 2 receptor (D2) and somatostatin receptor subtype (sst) 5. The expression of sst2 is relatively low because of downregulating effects of high endogenous cortisol levels. This may explain why the sst2-preferring somatostatin analog octreotide is not effective in CD. To assess whether normalization of urinary free cortisol (UFC) excretion modulates the sst expr...

Pituitary adenomas account for ~10% of intracranial tumors and result in morbidity due to both altered hormonal patterns as well as side effects of therapy. Currently, great attention has been given to preventive strategies, and in this context, the use of functional foods with chemopreventive compounds appears to contribute much in this process. Among these substances, we highlight the consumption of carotenoids is associated with reduced risk of chronic diseases including ca...

Background: Hypopituitarism after traumatic brain injury (TBI) is considered to be a prevalent condition, and may affect quality of life (QoL) and cognitive function. However, the prevalence of hypopituitarism differs considerably among reported studies due to differences in definitions, endocrine assessments of hypopituitarism, and confounding factors, like timing of evaluation and the severity of the trauma.Aim: To evaluate the prevalence of hypopituit...

Introduction: People with intracranial organic lesions, including pituitary tumours, may manifest initially as a psychiatric disorder, such as depression, emotional disturbance, anxiety, apathy, neurobehavioral disturbance, cognitive dysfunction and personality disturbance.Case Report: A male patient 45 years old was sent to the Department of Endocrinology of São João Hospital due to a pituitary macroadenoma. The patient referred asthenia, musc...

Background: Thyroid function, insulin resistance, serum lipid, C-reactive protein (CRP) and homocysteine are associated with an increased cardiovascular risk in patients with autoimmune thyroiditis (AIT).Objective: To evaluate the interrelations between thyroid function, insulin resistance, serum lipid concentrations, CRP and homocysteine in patients with AIT and subclinical hypothyroidism.Subjects and methods: We recorded thyroid ...

Background: Autoimmune thyroiditis (AIT) is associated with increased risk of cardiovascular disease.Objective: To evaluate the interrelationships between insulin resistance (IR) and other cardiovascular risk factors, such as high sensitivity CRP (C reactive protein) and homocysteine in patients with AIT.Patients and methods: We analysed thyroid function, anti-thyroid antibodies, BMI, indices of IR, such as HOMA-IR, HISI (Hepatic I...

Background: Thyroid dysfunction and lipid profile are associated with cardiovascular disease in patients with autoimmune thyroiditis (AIT).Objective: To evaluate the association between thyroid function, lipid concentrations, C-reactive protein (CRP) and homocysteine in patients with AIT.Patients and methods: We assessed thyroid function tests, BMI, total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, triglycerides (TG), apoli...

Aims: To examine whether treated autoimmune thyroiditis (AIT) and Graves’ disease (GD) are associated with increased cardiovascular risk factors.Patients and methods: We analysed the levels of total cholesterol (TC), HDL, LDL, triglycerides (TG), ApoB, ApoA1, Lp[a], homocysteine, CRP, folic acid and vitamin B12 in 50 patients with GD and in 130 patients with AIT, after normalization of thyroid function. Patients with GD were treated with propylthiou...

Objective: The aim of this study was to examine the hypothesis that thyroid function, in euthyroid subjects with autoimmune thyroiditis (AIT), is associated with insulin resistance, serum lipid concentrations, and other cardiovascular (CV) risk factors. Subjects and Methods: We recorded thyroid function tests, BMI, insulin resistance markers comprising the Homeostasis Model Assessment for insulin resistance (HOMA-IR), the Quantitative Insulin Sensitivity Check Index (QUICKI), ...
