IntroductionThe precocious puberty defines itself by the appearance of secondary sexual characters before the age of 9 years at the boy.We bring back the case of a precocious pseudo puberty iso sexual having evolved towards a central precocious puberty revealed by in an advance of secondary bony age in a delay of diagnosis.ATCD, accepted for reappraisal of a precocious pseudo puberty linked to a bilateral tes...

Background: The action of a steroid in any physiological process is dependent on the bioavailable (free) fraction. Direct measurements of free cortisol are expensive, labour intensive and require a significant volume of plasma and as a consequence are not feasible in the neonate. One alternative is to calculate free cortisol from the Cortisol Binding Capacity (CBC) and the total plasma cortisol. The aim of the present study was to develop an assay for the measurement of CBC in...

There are some data concerning high prevalence of infrasellar extension of somatotropinomas. To reveal any differences expansion of pitutary macroadenomas with various hormonal secretion, we have analyzed MRI data of 175 pituitary macroadenomas: 87 non-functioning adenomas (NFAs), 48 prolactinomas, 43 somatotropinomas. The sizes of pituitary tumour (vertical, sagittal, frontal): NFAs 24 (17.5; 34.5)mm, 23 (17.4; 28) mm, 23 (18; 30) mm; prolactinomas 21 (15; 31) mm, 20 (16; 30)...

The efficiency of the prolonged medical therapy of acromegaly with the somatostatin analogues (SA) strictly correlates with the initial sensitivity to the drug. Before the onset of SA therapy 114 patients with acromegaly (35 men and 79 women) aged 54 (48/61) years old (Me (25/75%) underwent the test with Octreotide (Sandostatin®): 300 μg sc within 3 days. The decrease of IGF1 level positively correlated with the age of the acromegaly onset (r=0.38) and negativ...

Background: Serotonin produced by ileum neuroendocrine tumors (i-NETs) promotes development of the mesenteric mass (MM) associated with lymph node metastases. We previously reported that more extensive MM progression along the superior mesenteric vessels predicts a lower rate of complete surgical resection. In this study, we hypothesized that tumoral serotonin production is associated not only with the development of MM but also its progression, and we examined serotonin level...

Metformin treatment of women with PCOS has been shown to improve ovarian function, reduce hyperandrogenicity and induce weight loss. The aim of this prospective study was to investigate the nature of the weight loss in obese women with PCOS, using 2 dose regimes.Methods: Obese (body mass index [BMI] > 29 kilograms /m2) women with PCOS (n = 44) were recruited to the study, and randomised to receive either 1500mg metformin daily (n = 22), or ...

Introduction: Alternative biofluids such as sweat, which can be obtained non-invasively and present a simpler matrix composition than serum/plasma or urine, may be useful for monitoring biomarkers. The long-term sampling with patches either on the chest or back can be conveniently used under both rest and exercise conditions to provide an integrated response of free biomarkers over the course of a day. The smaller sample volumes generated by sweat collection can be convenientl...

Background: The thyroid isthmus contains no C-cells, thus we established IPTB for cases with nodular goiter and moderate hypercalcitonemia (stimulated up to 350 pg/ml). In these cases C-Cell-Hyperplasia is the primary pathologic correlate. Exclusion criteria were pre- or intraoperative signs of malignancy.We furthermore established IPTB as a prophylactic operation for patients with hereditary medullary thyroid carcinoma, excluding high-risk mutations.</p...

Introduction: Glucagonomas are rare functional pancreatic neuroendocrine tumours (p NETs), with an annual occurrence of 0.01 to 0.1 new cases per 100,000. Objective: We focused on presenting symptoms, primary’s size and location, presence of metastases, biomarkers at diagnosis, histology, response to first line treatment (clinical and biochemical), disease fee survival (DFS) and PFS (progression free survival). Methods: Eighteen pa...

We analyzed data of 148 patients (125 female, 23 male) with hyperprolactinemia who had been investigated in our Department during 2008–2012: Nontumor hyperprolactinemia (NT, n=46, 31%), microadenomas (MI, n=56, 38%), MAcroadenomas (MA, n=46, 31%). Patients’ age was 36 (24; 46), 37 (26; 44) and 49 (33; 60) years respectively. Men were younger than women (P=0.002). Portion of men was higher in MA than in NT and MI: 19% vs 10...
