Aim: Thyroid cancer comprises the most common endocrine malignancy and a variety of studies have examined the incidence of microcarcinomas in benign thyroid disorders. Objective of the present retrospective study was the assessment of the possible influence of age and gender parameters in the presence of thyroid microcarcinoma in a patient cohort with non-autonomous thyroid disorders and without cytological establishment of cancer who underwent total thyroidectomy.<p class...

Introduction: Primary aldosteronism (PA) is the most common cause of endocrine hypertension. In recent studies, increased prevalence of hyperparathyroidism (HP) has been observed in PA patients. However, the prevalence of HP in overt or milder forms of PA has not been evaluated yet.Objectives: To estimate the prevalence of HP in patients with PA (overt and milder forms) and investigate the effect of treatment (eplerenone or surgery) on PTH secretion....

Introduction: The clinical profile of patients with primary hyperparathyroidism has changed significantly in the last decades considering the fact that most cases are asymptomatic. This could be attributed to early diagnosis due to routinely serum calcium measurement. Only 5–27% of patients present with symptoms or signs related to osteoporosis, nephrolithiasis and hypercalcaemia. However, in patients with asymptomatic primary hyperparathyroidism (APHP) data concerning t...

Introduction: The molecular pathogenesis of pancreatic neuroendocrineneoplasms (PNEN) is increasingly yet incompletely understood. PNEN typically occur sporadically or may occur within the context of hereditary tumor predisposition syndromes. PNEN can also be associated with endocrinopathy of hormonal hypersecretion. We present a young male with a multi-hormonal neuroendocrine neoplasm of pancreas.Case presentation: A 24-year-old male, non-smok...

Background: The ITT has been said to be the gold standard for diagnosing GH deficiency (GHD) for 50 years. The original 0, 20, 30, 60, 90 and 120 min time points are still used in many but a survey of current UK paediatric ITT protocols identified several variations.Objective and hypotheses: To identify optimal GH sampling time points to avoid over diagnosis of GHD.Methods: Results of 502 paediatric ITTs using two different samplin...

Introduction: The aim of this study was to examine whether the distribution of SHBG (TAAAA)n repeat variants contributes to the exposure of the female fetus to androgen excess, by influencing the, in utero, androgen availability.Methods: The study population consisted of 100 pregnant women that carried female fetuses and underwent the procedure of amniocentesis due to age (older than 35). Blood samples and amniotic fluid samples were dr...

Aberrant adrenal LH expression is a rare cause of adrenal Cushing’s syndrome (CS) leading to transient hypercortisolism during pregnancies and ACTH-independent macronodular adrenal hyperplasia (AIMAH) after the sustained postmenopausal increase of LH secretion. Subclinical CS due to aberrant LH expression has very rarely been described. Herein, we report a case with aberrant LH/hCG adrenal receptor mediated subclinical CS in a patient with incidentally discovered AIMAH an...

Objective: Numerous studies have reported an increased risk of gestational diabetes mellitus (GDM) among women who are overweight or obese compared with lean or normal-weight women. Obesity contributes to multiple health problems during pregnancy and predisposes a woman to develop GDM. Obesity is defined as a body mass index (BMI) of >30. Overweight is defined as a BMI of 25.0–29.9 and normal weight is defined as a BMI 20–24.9. The aim of the present study was to...

Background-aim: Increased serum cholesterol and triglycerides levels may have a role in the development of gestational diabetes mellitus (GDM) and its complications. This study was designed in order to provide a description of lipids profile by gestational age during pregnancy.Subjects and methods: We studied 211 women from the outpatient clinic of metabolic disorders in pregnancy. These women were ordered to perform the oral glucose tolerance test (OGTT...

Background-aim: Normal thyroid function during pregnancy is critical for fetal development. Deficient maternal thyroid hormone levels are associated with impaired neuropsychological development in childhood, premature birth, preeclampsia and fetal mortality. Conversely, excessive maternal thyroid levels have been linked to fetal loss, disturbed fetal growth, preeclampsia and preterm delivery. Recent consensus guidelines do not advocate universal thyroid function screening duri...
