Single nucleotide polymorphisms (SNPs) of the LIN28B gene and age at menarche in a sample of Greek girls

Tsinopoulou Vasiliki-Rengina , P. Kotanidou Eleni , Bacopoulou Flora , Fidani Liana , Gerou Spyridon , Galli-Tsinopoulou Assimina , Christoforidis Athanasios

Objectives: Menarche is defined as the first menstrual bleeding in females, and the age of onset varies and depends on a complex interaction between genetic and environmental factors. The LIN28B gene single nucleotide polymorphisms (SNPs) rs314276, rs7759938 and rs314280 appear to be associated with cases of premature and early menarche. International databases report that the presence of a G allele of rs314280SNP shifts menarche 1.2 months earlier, a C allele...

Central precocious puberty (CPP) results from premature activation of the hypothalamic-pituitary-gonadal axis through the activation of the gonadotropin releasing hormone (GnRH). Gain-of-function mutations of the KISS1 and KISS1R genes or loss-of-function mutations of the makorin RING-finger protein 3 (MKRN3) have been linked with CPP. Moreover intronic and intragenic variants harbouring the imprinted loci of MKRN3-MAGEL2 and DLK1 g...

Background: Central precocious puberty (CPP) results from premature activation of the hypothalamic-pituitary-gonadal axis and increasing evidence suggests a genetic origin. Premature activation of the GnRH secretion in CPP may arise either from gain-of-function mutations of the KISS1 and KISS1R genes or loss-of-function manner mutations of the MKRN3 gene leading to MKRN3 deficiency.Objective and hypotheses: To identify loss-of-...

Background: Pediatric growth hormone deficiency (pGHD) is associated with growth attenuation/deceleration, short stature, delayed bone maturation, and metabolic defects. Daily recombinant human growth hormone (rhGH) treatment promotes linear growth and increases growth rate; however, it may present a substantial burden for patients and caregivers. This may lead to low adherence, limiting the clinical effect of treatment. This study assesses the health-related ...

Background: Transient generalized glucocorticoid hypersensitivity is a rare disorder characterized by increased tissue sensitivity to glucocorticoids and compensatory hypoactivation of the hypothalamic–pituitary–adrenal (HPA) axis. The condition itself and the molecular mechanisms that underlie its pathophysiology have not been elucidated as yet. Adenovirus 36 has been reported to cause obesity in various animal species.Objective and Hypotheses...

A rare case of Type 1 Diabetes preceded by Hashimoto thyroiditis and followed by Multiple Sclerosis

Karabouta Zacharoula , Bisbinas Vasiliki , Evangeliou Athanasios

Introduction: Type 1 Diabetes(T1) and autoimmune thyroid disease(AITD) can occur concomitantly. Multiple sclerosis(MS), a chronic condition resulting from dysfunction of the immune system, may co-occur with T1D.Aim: We present a 17-year-old boy presented with AITD at 10y old and within seven years developed T1D and MS.Subjects and methods: The patient presented at the age of 10y ol...

Introduction: Neuropathy, as a complication of type 1 diabetes (T1D), is a heterogeneous group with chronic polyneuropathy being the most frequent form. Acute mononeuropathy is rare and its pathophysiology has not been elucidated.Purpose: To describe acute mononeuropathy during the course of severe ketoacidosis in an 8-year-old girl diagnosed with T1D.Case report: An 8-year old girl was admitted to the Emergency Department because ...

Kosteria Ioanna , Gkourogianni Alexandra , Papadopoulou Aggeliki , Anagnostopoulos Athanasios , Chrousos George , Tsagaris George , Kanaka-Gantenbein Christina

Background: Several studies have correlated Assisted Reproduction Technologies (ART) including classic IVF and Intacytoplasmic Sperm Injection (ICSI) with epigenetic alterations in the offspring that could have long lasting unfavorable metabolic effects. Proteomics, a state-of-the-art technology used for the identification of early biomarkers of disease, has already been implemented in the search of success in ART but not yet for such markers evaluation in offspring of ART.</p...
