Introduction: Cushing’s Disease results of corticotrophin (ACTH) hypersecretion from pituitary which increases cortisol production. WHO classified pituitary tumors as typical adenoma, atypical adenoma and carcinoma. Diagnostic criteria for an atypical adenoma include invasive growth, elevated mitotic index, Ki-67 labeling index greater than 3% and extensive p53 immunoreactivity.Case Report: Sixty-eight years-old man presented to our consult with his...

Objective: Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) excess results in both reversible and irreversible damage to the skeleton, and includes increased vertebral fracture (VF) risk in the presence of normal BMD. The prevalence of VFs is approximately 60% in controlled acromegaly patients, and these VFs can progress during short-term follow-up. We aimed to identify the course of VFs and their associated risk factors in a cohort of acromegaly patients in long-t...

Objective: Self-reported volume of patients and specific interventions is a specific network criterion that needs to be fulfilled by reference centres that are eligible for inclusion within Endo-ERN. The aim of the present study is to evaluate how self-reported volume data in the original applications were obtained, which data are retrievable, and which set is best suitable to use for future centre evaluations. This overview is provided for two Main Thematic Groups (MTGs) of E...

Introduction: It is universally accepted that calcitonin (CT), a hormone secreted by the parafollicular cells of the thyroid, is a specific, sensitive and early marker of Medullary Thyroid Carcinoma (CMT), with higher diagnostic accuracy than fine needle aspiration biopsy(FNAB). However, the routine measurement of serum CT during assessment of nodular thyroid disease (NTD) remains controversial due to rarity of this cancer and possible false positive results.<p class="abst...

Background: Malignant hypercalcemia (MH) occurs in up to 30% of patients who are diagnosed with cancery, being associated with later stages of the disease and poor prognosis. The physiopathological mechanisms responsible for MH are the production of parathyroid hormone-related peptide by the tumor (PTHrp) (80% of cases), osteolytic cytokine production (20%) and excess of 1,25(OH)2vitamin D production (1%).Case report: We present the case of a ...

Introduction: Cushing’s syndrome (CS) is a well-known cause of bone loss and osteoporotic fractures, which may be the initial manifestation of the disease and may present 2 years before CS diagnosis. Trabecular bone is usually the most seriously affected, and vertebrae and ribs are the typical fracture locations.Case report: A 37-year-old man with dyslipidemia and obesity was observed due to uncontrolled hypertension and osteoporosis. He complained ...

Polycystic ovary syndrome (PCOS) is an important metabolic and reproductive disorder which confers substantially increased risk for type two diabetes and metabolic syndrome (MS). Our aim is to characterize the metabolic profile, insulin sensitivity (IS) and insulin secretion in control (Cw) and PCOS women (PCOSw) during different stages of reproductive life (S1: 18–35 years old, S2: 36–44 years old, S3: 45–55 years old). A total of 131 Cw and 129 PCOSw were incl...

Introduction: Germ cell tumors (GCTs) are classified as extragonadal if there is no evidence of a primary tumor in the gonads. They typically occur in the midline structures. Newly diagnosed adult cases of pituitary or pineal glands germinomas are very rare since most of the cases are diagnosed in the mid teens, presenting 14:1, on behalf of the male gender. The estimated incidence of this tumor in western countries is between 0.4–3.4%, being more frequent in the Asia.</p...

Introduction: Premature pubarche (PP) is most often related to idiopathic premature adrenarche (IPA). However, it is a diagnosis of exclusion and differential diagnosis must include milder and nonclassic variants of congenital adrenal hyperplasia (CAH).Purpose: To identify clinical predictors of CAH and IPA in children with PP.Materials and methods: A retrospective study was conducted including children seen for PP between 2001 and...

Objective: To examine whether Graves’ disease (GD) and autoimmune thyroiditis (AIT) are associated with insulin resistance and other cardiovascular risk factors.Subjects and methods: We recorded thyroid function tests, BMI, insulin resistance markers comprising the homeostasis model assessment for insulin resistance (HOMA-IR and HOMA-B), the quantitative insulin sensitivity check index (QUICKI), hepatic insulin sensitivity index (HISI), whole-body i...
