Assessment of Initial Investigation Requested in Adolescents with Menstrual Disorders

Charamanta Maria , Michala Lina , Drakakis Peter , Yasmin Ephia , Creighton Sarah

Backround: Menstrual disorders are common among the adolescent girls. We examined the initial investigations performed in adolescents, presenting with frequent, heavy or painful periods. Although, usually abnormal uterine bleeding (AUB) in adolescent women is attributable to immaturity of the hypothalamic-pituitary-ovarian axis, underlying conditions such as coagulation disorders and anemia should always kept in mind. However, neither the laboratory nor the ultrasound investig...

Feasibility Study for Avoiding Early Surgery in Girls with 21-Hydroxylase Deficiency (21OHD)

Bougneres Pierre , Bouvattier Claire , Cartigny Maryse , Michala Lina

Background: Genital surgery in disorders of sex development (DSD) has been an area of debate over the past 20 years. One can question and even defy the routine practice to surgically align genitalia to the sex of rearing, as early as possible. However, despite multitude of data showing detrimental effects to genital sensation and sexuality, few patients born with ambiguous genitalia have remained unoperated into adolescence.Objective and hypotheses: To a...

The proband is a 12 yr old Caucasian European girl with grade 3 obesity, developmental delay and hyperphagia. She was born at term via an uncomplicated pregnancy and exhibited neonatal hypotonia, difficulty feeding, failure to thrive and delayed attenuation of milestones. At the age of 2 years she started developing hyperphagia and rapid excessive weight gain. Molecular analysis for Prader Willi syndrome and array CGH were negative. At the age of 10 yrs she was diagnosed with ...

A Novel Germline DICER1 Mutation in a Girl with Multinodular Goiter and Ovarian Sertoli-Leydig Cell Tumor

Background: DICER1 is an endoribonuclease that acts post-transcriptionally by processing mRNA into siRNA and microRNA, thus leading to mRNA downregulation. DICER1 syndrome is usually caused by germline variants and is characterized by a variety of benign or malignant tumors: pleuropulmonary blastoma, ovarian Sertoli-Leydig cell tumor, cystic nephroma, pituitary blastoma and multinodular goitre. Patients with germline aberrations in the DICER1 gene may carry additional...

Search for Genetic Defects in the Transcription Factor Genes FOXL2, FOXE1, BMP15, NOBOX, and GDF9 in Children, Adolescents and Young Adults With Premature Ovarian Insufficiency POI

Background: Molecular defects are rarely detected in Premature ovarian insufficiency (POI) patients.Objective and Hypotheses: We hypothesized that the frequency of causative molecular defects could be higher in cases with early onset of POI. Moreover, the analysis of multiple genes in the same POI group could disclose co-existence of more than one molecular aberration.Method: In 25 subjects, aged 17.1±7 years at POI onset, bid...

Co-Existing Variants of FOXE1 and BMP15 Genes in Young Females with Primary Ovarian Insufficiency: Evidence of Digenic Inheritance

Background: FOXE1 gene variants containing alterations in the alanine tract length may confer susceptibility to primary ovarian insufficiency (POI). BMP15 gene variants have also been related to POI.Objective and hypotheses: To evaluate the contribution of FOXE1 and BMP15 variants in the pathogenesis of POI and to investigate the hypothesis of digenic inheritance in this disorder.Method: FOXE1 and BMP...
