A 34-year-old female was seen in the joint diabetic antenatal clinic during her second pregnancy. She had a very unfortunate first pregnancy, which resulted in a still birth following a traumatic delivery. She also had a large post-partum haemorrhage causing Sheehan’s syndrome. Hormone replacement therapy had been commenced, including hydrocortisone, thyroxine and growth hormone (GH). Pre-treatment quality of life assessment in GH deficient adults score (Qol-AGHDA) 21, an...

Objective: Ovarian cryopreservation is an emerging technique that may advance breeding of endangered species and preservation of reproductive capacity in young women cancer patients who will undergo chemo/radiotherapy destruction of ovarian tissue.Materials and methods: A total of twelve mature female rabbits were used in experiment. Rabbits were anesthetized and then subjected to laparotomy. Bilateral oophorectomy was used to save one ovary as fresh con...

T3 and fibroblast growth factors (FGFs) are critical regulators of chondrocyte proliferation during bone formation and we identified recently that T3 modulates skeletal FGF receptor-1 (FGFR1) activity. FGFRs signal via several routes including mitogen-activated protein kinase (MAPK), STAT and phospholipase C gamma pathways. Mechanisms determining which pathways are activated by FGFRs are poorly understood but include alternative splicing of exons encoding variable domains with...

In human GL cells, 11beta-HSD catalyses the interconversion of cortisol (F) with its inert 11-ketosteroid metabolite, cortisone (E). Since GL cells synthesise prostaglandins (PGs), and PGs have been shown to modulate the expression and activity of the cloned 11beta-HSD enzymes, the objective of the present study was to establish whether locally synthesised PGs affected the net oxidation of F to E by 11beta-HSD in human GL cells recovered from the ovaries of women undergoing co...

Local glucocorticoids action depends on 11β hydroxysteroid dehydrogenase (11β-HSD) enzymes. Adipose tissues mainly express the 11β-HSD1, which activates inactive cortisone. Altered 11β-HSD1 and GLUT4 expressions have been reported in obesity. GLUT4 participates in the genesis and maintenance of insulin resistance/obesity, and could also be involved in the insulin resistant state observed in hypercortisolism. The aim of this study was to investigate the 11&#...

To investigate the blood pressure profile (BP) in active acromegaly and the effect of medical treatment of acromegaly on BP circadian rhythm, we studied 21 acromegalics before and after 3–60 months of treatment with somatostatin analogs (15/21) or pegvisomant (5/21) or both (5/21). Ambulatory 24-h BP was recorded. The 24-h mean BP (MBP), the mean systolic BP (SBP) and diastolic BP (DBP), the day-time (day) and night-time (night) MBP, SBP and DBP and the 24-h mean heart ra...

Long-term benefit-risk ratio of IT remains poorly evaluated. The aim of this work was to determine the evolution of macroangiopathic complications 5 years after IT.21 out of the 36 prospectively followed islet-transplanted patients in a single center, had at least 5 years of follow-up and were included. Their initial features were: duration of C-peptide negative diabetes: 28±9years; age: 43±7years; BMI: 24±0.2 kg/m2; 8/21 kidney-transplant...

LHX3, a member of the LIM-homeodomain family of developmental transcription factors, is required for establishment of mammalian anterior pituitary hormone-secreting cell types as well as the formation of specialized neurons of the nervous system. Paediatric patients with pituitary insufficiency are sometimes diagnosed with combined pituitary hormone deficiency disease (CPHD). This disease can be linked to mutations in essential pituitary developmental transcription factor gene...

Objectives: To investigate how the immune associations (IA) may have significance for diagnosis or therapy in thyroiditis.Material and method: Patients: A. ‘Classical’ Hashimoto thyroiditis (hyper-ATPO-emia, HT) =1092, B. thyroiditis with isolated hyper-ATG-emia, with normal ATPO (T-ATG) =61, C. thyroiditis ‘sero-negative’ (normal ATPO and ATG, pathology diagnosis) =5, D. idiopathic myxedema (hypothyroidism, no A, B,C) =70; E. control...

Introduction: In type-1 neurofibromatosis (NF-1) there is an increased risk of endocrine tumors, especially pheochromocytomas, whereas thyroid carcinomas seem to be extremely rare, with few cases reported in literature.Subjects and methods: In order to investigate the frequency of hypercalcitoninaemia and medullary thyroid cancer (MTC) in patients with NF-1, we evaluated the thyroid gland morphology and function in 17 patients with NF-1 by i) neck US, ii...
