Introduction: Both TSH and prolactin serum levels within normal range were previously reported to be associated with metabolic parameters.Aim: To analyse the connections between serum levels of prolactin, TSH, and insulin resistance in polycystic ovary syndrome patients.Material and methods: 322 PCOS patients (mean age 24.3±5.16 years and mean BMI 28±7.57 kg/m2) with normal serum prolactin and without thyroid d...

Background: Pituitary adenomas (PA) are slow-growing, benign intracranial tumors. Rarely, they can be histologically and clinically aggressive.Aim: To present a case of corticotroph PA with aggressive behavior following a long indolent interval after the initial surgery.Case presentation: A 47 years old female presented in Nov 2007 with right temporal hemianopsia and left eye blindness, associating type 2 DM and severe mixed dyslip...

The multiple endocrine neoplasia syndrome type 2A (MEN 2A) is the consequence of a heritable mutation in the RET proto-oncogene, leading to a very high predisposition to develop medullary thyroid carcinoma (MTC), pheochromocytoma and primary parathyroid hyperplasia. Screening of ‘at-risk’ family members and prophylactic thyroidectomy is recommended – but not always easily accomplished.Our proband was diagnosed with MTC in 1977 (at age 21),...

Background: Higher anti-Müllerian hormone (AMH) values are associated with polycystic ovary syndrome (PCOS) and AMH is proposed as a marker of PCOS, however, the optimal diagnostic threshold is not yet defined.Aim: To study the significant correlations of AMH in PCOS and the accuracy and threshold of AMH for the PCOS diagnosis in Romania.Subjects and methods: Serum AMH, TT, LH, FSH, fasting glucose and insulin (Ins), HOMA-IR a...

Experimental autoimmune thyroiditis (EAT) has been used to simulate human autoimmune thyroid disease for decades. EAT can be easily induced in genetically susceptible strains of mice by excess iodine ingestion or by immunization with mouse thyroglobulin. Excess iodine may induce and exacerbate autoimmune thyroiditis (AIT) in humans and animal models. In order to assess the potential protective mechanisms of selenium (Se) in thyroid autoimmunity, we evaluated the effects of ino...

Introduction: Paraneoplastic Cushing’s syndrome is attributed to ectopic ACTH release from a non-pituitary tumor. The lung is frequently the primary site of the underlying neoplasm but sometimes, in cases of advanced metastatic disease, determining the origin may be challenging.Case presentation: A70-year-old man was reffered to our centre for generalised bone pain, lethargy, and important weight loss in the last six months. Before admission, a cont...

Aim: To show that height loss is more correlated with vetebral micoarchitecture than with Bone Mineral Density (BMD). Material and Method: A. DEXA: made with a GE-Lunar Prodigy Pro # 500074. Vertebral microarchitecture was investigated by Trabecular Bone Score (TBS). TBS software: TBS iNsight®, version 3.0.2.0.B. Patients. 902 patients, 844 (93.6%) women, 58 men. Only 42 under 50 years. Age av...

Background: Giant prolactinomas are rare pituitary tumours larger than >40 mm in diameter, representing 2–3% of prolactin secreting tumours. Management is challenging especially in male patients, due to resistance to dopamine agonists (DA).Methods: Clinical, hormonal and imaging evaluation and follow-upAim: To describe a case of partially resistant giant prolactinoma in a young male patientCase repor...

Background: PA is a frequent cause (5–13%) of secondary hypertension (HT), yet diagnostic work-up of PA remains challenging.Aim: To describe the characteristics of hypertensive patients diagnosed with PA, biochemical screening (aldosterone:renin ratio/ARR), confirmatory tests, and adrenal CT results.Methods: Clinical, hormonal and imaging evaluation.Results: 13 patients (7M/6F) with PA were 45 yrs (40&#1...

Background: Association of differentiated thyroid carcinoma (DTC) and cortisol-producing adrenal adenoma is not part of the classical MEN syndromes. We present a clinical case raising the question of a common etiology for these tumours.Case Presentation: A 58-year-old female presented in 2010 for the investigation of a 6 cm left adrenal tumour incidentally discovered by abdominal CT. Medical history included smoking, obesity, myocardial infarction, hyper...
