Introduction: 17th European Congress of Endocrinology 2015. The skeleton health is reflected by the turnover markers as serum CrossLaps (CL=bone resorption), and serum osteocalcin (OC=bone formation), and by the calcium metabolism parameters (as ionic blood calcium, and, probably, by the 24-h urinary calcium=24-h ca). The peripheral serotonin might have intra-normal levels in patients with osteoporosis but yet represents a part of the complex equation related to the bone homeo...

Introduction: SOX2 is an early developmental transcription factor and a marker for pituitary progenitor cells.The study aimed to investigate if the pituitary adenomas with positive SOX2 immunoreactivity shows a different response to therapy as compared with controls.Patients and methods: We investigated 15 pituitary macroadenomas, eight with SOX2 immunoreactivity (SOX2+) and seven without (SOX2−) (controls); five were GH prod...

Background: Craniopharyngioma is a rare, mostly benign tumor of the central nervous system, generally associated with important morbidity.Aim: To study the clinical characteristics and treatment outcome in adult patients.Methods:: Adult patients diagnosed with craniopharyngioma between 1980 and 2012, followed-up in the Pituitary and Neuroendocrine Department of the ‘C.I.Parhon’ National Institute of Endocrinology in Bucha...

There are difficulties in establishing the diagnosis of gonadotropinomas using serum hormonal levels, even after intravenous TRH. We evaluated the relationship between humoral (serum and cerebrospinal fluid - CSF) levels of gonadotropins and the immunohistochemical evidence in tumor tissue.Serum and CSF levels of pituitary hormones were assayed using rapid fluoroimmunometry with Europium. Immunohistochemistry (IHC) was performed with avidin-biotine. Grou...

Introduction: We report a case of Cushing’s syndrome association with nephrotic syndrome in a patient with occult ectopic ACTH (EAS) secretion by a bronchial carcinoid and resolution of both disorders after bilateral adrenalectomy.Case report: A 42-year-old man was admitted to our department with the suspicion of EAS. He was in a very good health until several months ago when he developed suddenly nephrotic syndrome, severe hypertension, severe hypo...

Objective: The analysis of the copy number variation of CYP21A2 gene in a cohort of 21-hydroxylase deficiency (21-OHD) pediatric patients in a tertiary referral center from Romania.Methods: A total of 24 patients (21 female and 3 male, 7:1 female to male sex ratio) with previously biochemically and clinically diagnosed 21-OHD were enrolled in this study from October 2020 to October 2021. The age at the diagnosis was 4.6±4.8 years (mean&#177...

Medullary thyroid carcinoma (MTC) is a rare malignancy arising from parafollicular C cells of the thyroid gland, sometimes due to germline mutations in the RET protooncogene. Testicular cancer is the most common malignancy in men aged 15 - 40 years with survival rates improved by the introduction of cisplatin therapy in the late 1970s. Nonetheless, platinum-based chemotherapy was shown to increase the risk of a solid second cancer with substantially increased site-specific ris...

Introduction: 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder and the diagnosis is confirmed by the presence of at least two biallelic pathogenic variants. The phenotype is determined by the less deleterious variant. The relevance of hormonal assessment to distinguish between heterozygote carriers of pathologic mutations and non-carriers or genetically defined 21OHD patients is still a matter of debate. Identifying the heterozygous genotype is important in...

Introduction: Thresholds of basal (bCT) or stimulated serum calcitonin (sCT) levels for the diagnosis of medullary thyroid carcinoma (MTC) aren’t specified in current revised MTC guidelines.Objective: We aim to setfemale (F) specific thresholds for bCT and sCT for MTC diagnosis.Methods: CT samples were measured during calcium-stimulation test (25 mg/kg BW adapted to ideal body mass index) before and at 2, 5 and 10 minutes afte...

Introduction: The deregulation in miRNA expression has been described in thyroid tumors, and is considered an important factor in thyroid carcinogenesis. mRNA expression profiling in cancer allows identifications of signatures associated with diagnosis, staging, prognosis, and response to treatment.Objective: We aimed to detect miRNAs species differentially expressed between tumor and peritumoral tissue in papillary thyroid carcinoma.<p class="abstex...
