Introduction: Central diabetes insipidus (CDI) occurs due to deficient secretion of arginine vasopressin (AVP) or antidiuretic hormone (ADH) by the posterior pituitary. It is a rare disease with an estimated prevalence of 1:25000. CDI can be acquired or congenital, secondary to malformation or genetics. Familial CDI (genetic inheritance) is mainly autosomal dominant. More than 80 mutations in the AVP gene have been described. In hereditary CDI, the age of onset is variable. Sy...

Background: Graves’ disease (GD) is a common autoimmune disease of unknown origin. Evidence of an association between autoimmune thyroid diseases and viral infections is, however, emerging. Human leukocyte antigen (HLA) class I presents both virally and self-derived antigens to circulating immune cells and plays a crucial role in the defense against viral infections. This study aimed to investigate the presence of enterovirus and HLA class I expression in a large GD coho...

Background: By regulating the concentration of active estrogens in tumor cells, steroid hormone-inactivating estrogen sulfotransferase (SULT1E1) and estrogen activating steroid sulfatase (STS) may influence the progression of EOC. Therefore, we determined the expression and prognostic impact of both enzymes together with the ERα/β and the progesterone receptor (PGR) in this tumor entity.Methods: The mRNA expression levels of STS, SULT1E1, ER&#9...

Facing a cancer diagnosis at any age is devastating. However, young cancer patients have the added burden that life-preserving cancer treatments, including surgery, chemotherapy, and radiotherapy, may compromise their future fertility. The possibility of reproductive dysfunction as a consequence of cancer treatment has a negative impact on the quality of life of cancer survivors. The field of oncofertility, which merges the clinical specialties of oncology and reproductive end...

Introduction: A Patient Held Record (PHR) has been developed for use in adolescent girls with Turner Syndrome (TS) attending a dedicated Turner Transition clinic, RHC Glasgow. The PHR has been devised to encourage knowledge of TS; medcial care and ways to maintain good health and to promote self advocacy.Aim: To assess patient acceptability and user friendliness of a PHR in adolescent girls with TS.Method: A PHR and questionnaire w...

Introduction: Chemokines are small secreted molecules that promote cell survival, proliferation and directional guidance of migrating cells in normal physiology and tumour pathophysiology. We have recently observed high CXCR4 mRNA expression both in normal human adrenals and in adrenocortical carcinomas. Furthermore, a PET tracer for selective molecular imaging of CXCR4-expression has recently been established.Objective: To further investigate CXCR4 prot...

Background: Anti-Müllerian hormone (AMH) is a key regulator of preantral follicle development. In human polycystic ovarian syndrome (PCOS) hyperandrogenism drives antral follicle excess, and is associated with elevated AMH levels. It is currently unknown if androgens regulate AMH secretion.Objective and hypothesis: To provide insights into the regulation of AMH action, we hypothesized that dihydrotestosterone (DHT), the most potent androgen, stimula...

The clinical picture of hypothyroidism is well described. It is well known that thyroid hormones are very important to development and maturation of the central nervous system. They have influence on the synthesis of proteins and production of enzymes and myelin.Myelin synthesis is an important factor in determining the speed of impulse transmission along complex polysynaptic pathways, such as those mediating the evoked potentials....

Background: Current dogma states that in autoimmune Addison’s disease (AAD), all adrenocortical function eventually is lost. Yet growing evidence suggests that a subgroup of patients retain some self-production.Aim: To explore whether residual production of adrenocortical steroids is present in a subgroup of AAD patients.Material and methods: In an open non-randomized cross-sectional study, an interim of 22 AAD patients delive...
