Amenorrhea and Hypothalamic–Pituitary Dysfunction

Pitteloud N

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....

Protective Potential of Metformin on Membrane Linked Functions in Diabetic Aging Female Rats

Kumar Pardeep , Baquer N

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 ...

New Syndromes Resulting in Secretory Pathway and Gonadotropic Axis Regulation Defects

de Roux N

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...

Secretion of Somatostatin and Growth Hormone (GH) in Various Forms of Hereditary Pathology

Muhamedov R.S. , Ibragimova N. Sh. , Dalimova D.

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...

Does Acquired Hypothyroidism Lead to Precocious Puberty?

Aydın Dilek , İşguven Pınar , Aydın Engin

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...

Monogenic Diabetes in a Paediatric Population: Finding the Needle in the Haystack

Mavinkurve M , Johnston N , Carroll A , Donnell C Mc , Byrne M M , Murphy N P

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...

Effects of combined treatment with rhIGF-I and metreleptin in a girl with the severe insulin resistance Rabson-Mendenhall syndrom

Genthner N. , Rakicioglu H. , Karatsiolis P. , Wudy SA , Kamrath C.

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...

Random Luteinizing Hormone Concentrations for Monitoring Central Precocious Treatment Efficacy

Zeitler Philip , M. Boldt-Houle Deborah , N. Atkinson Stuart

Background: A decrease in random LH concentration is observed after initiation of treatment for central precocious puberty (CPP), but the suitability of random LH concentrations for assessing efficacy is controversial. Although Neely et al. reported that random LH values frequently fail to demonstrate suppression to prepubertal levels,1 Lee et al. demonstrated that a cutoff of random LH <0.6 IU/l may be adequate for monitoring s...

Prevalence and Ethiologic Factors of Hirsutism in Adolescents

Kaplan Nılgun , Orbak Zerrin , Doneray Hakan

Aim: To investigate the prevalence of hirsutism among adolescents using the modified Ferriman-Gallway (FG) Scale and to determine etiological factors in childen with hirsutism.Materials and methods: The study was in 2380 female adolescents aged 12–18 years. The modified FG score was used in the diagnosis and monitoring of hirsutism. Scores of 8 or above were regarded as hirsutism. Two hundred thirty-three volunteers determined as having hirsutism we...

Absence of Uptake on Scintigraphy Does Not Always Correlate with Athyreosis: Re-evaluation of Patients Diagnosed with Athyreosis Over a 10 Year Period in the Republic of Ireland

McGrath N , Hawkes CP , Ryan S , Mayne P , Murphy NP

Background: Thyroid imaging is recommended to determine the aetiology of congenital hypothyroidism (CHT). Currently scintigraphy is the gold standard imaging modality. Negative scinitigraphy despite the presence of thyroid tissue may lead to a spurious diagnosis of athyreosis. Few centres routinely perform both scinitgraphy and ultrasound so that the incidence of misclassified athyreosis is unknown.Aim: To describe the incidence of sonographically normal...
