Female reproductive disorders due to a hypothalamic–pituitary defect include hypothalamic amenorrhea (HA), polycystic ovarian syndrome (PCOS) and hyperprolactinemia. This talk will review the clinical presentation of HA, PCOS and hyperprolactinemia in adolescents and young adults and will provide an overview of recent clinical advances in the field....

Objective: The objective of this study was to investigate protective potential of metformin on membrane linked functions and glucose transporter in diabetic aging female rats.Background: The emerging view is that diabetic brain features many symptoms that are best described as accelerated brain aging.Methods: Young (3 months) adult (12 months) and aged (24 months) rats will be diabetic by using alloxan monohydrate. After metformin ...

Puberty is defined by the appearance of secondary sexual characteristics and the maturation of reproductive function. It is driven by an increase in sexual steroid hormone synthesis under the control of the gonadotropic axis. The key event in puberty initiation is an increase in the pulsatile release of the GnRH by hypothalamic neurons, triggering the release of LH and FSH. This pubertal increase in GnRH secretion is associated with increases in glutamatergic inputs and decrea...

Background: Patients with HP have stunting of various degree of expression but the most pronounced stunting is found in patients with Russell-Silver syndrome, Sekkel syndrome and Cornelius de Lange syndrome which is associated with disorders in the hypothalamus – hypophyseal system (somatostatin - GH).Objective and hypotheses: To study secretion of somatostatin and insulin-like growth factor (IGF-1, IGFBP-3) in various forms of hereditary pathologie...

Introduction: Hypothyroidism without treatment usually leads to delayed puberty in pediatric patients, sometimes it may rarely lead Van Wyk Grumbach syndrome (VWGS) which is characterized by isosexual precocious puberty. Exact mechanism of VWSG is unknown. High thyroid stimulating hormone (TSH) levels may directly effect on follicular stimulating hormone (FSH) receptors and lead precocious puberty. Interestingly simple thyroid hormone replacement therapy resolves symptoms in t...

Background: Ireland has a high incidence of type 1 diabetes in childhood (16.8/100, 000 per year (1). A small percentage of children with diabetes have maturity onset diabetes of the young (MODY) (2). Establishing the correct diagnosis is critical to optimal therapy and future genetic counselling (3).Objective and hypothesis: To review the cohort of children attending our tertiary diabetes service and describe the clinical features of those where MODY wa...

Introduction: The stanniocalcins (STCs) are inhibitory factors of the growth-promoting effects of IGFs through inactivation of pappalysins that favor the release of IGFs from their binding proteins (IGFBPs). STC1 can be involved in the cellular response to stress and plays an important role in cell cycle regulation. Patients with Fanconi Anemia (FA) are more sensitive to oxidative stress that could alter the expression of STC1. Our aim was to assess whether pa...

Background: Pituitary resistance to exogenous thyroxine (RETH) refers to persistently elevated serum TSH levels despite high/normal T4 concentrations in levothyroxine-treated patients. The underlying mechanisms and natural history of RETH in children with congenital hypothyroidism (CH) are not well known.Objective: We aimed to describe the possible mechanisms and natural history of RETH in children with CH.<p class="...

Background: Primary ovarian insufficiency (POI), characterized by amenorrhea with elevated gonadotropin concentrations, includes a spectrum ranging from 46, XX gonadal dysgenesis to premature menopause. There is increased evidence that it has a strong genetic basis in its etiology, however, since its rarity and special condition that does not permit the definition of families with this disorder, the molecular diagnosis remains elusive in most of these patients...

We present the case of a now 11 years old girl with the ultra-rare severe insulin resistance Rabson-Mendenhall syndrome due to the previously undescribed compound heterozygous mutations exon 16: c.2986A>G (Paternal) and intron 9: c.2029+1G>T (maternal) of the insulin receptor gene. The phenotypic findings were composed of dystrophy (birth weight 1970g, small for gestational age), hyperglycemia (up to 400mg/dl), severe acanthosis nigricans and mild cardiac septal hyperpla...
