Birkebaek Niels H. , Schørring Mia E. , Frederiksen Hanne , Kamperis Konstantinos , Kristensen Kurt , Rittig Søren , Juul Anders , Vestergaard Esben T

Background: The female gonadal axis is activated in mini-puberty and thereafter it is quiescent until puberty. We have shown that many girls with no clinical sign of puberty in the age group 1-6 yr. have a rather strong luteinizing hormone (LH) and follicle stimulating hormone (FSH) response to a gonadotropin releasing hormone (GnRH) test. However, stimulated LH and FSH values decreased in the age interval 1-6 yr and no LH/FSH values rose above 0.43. Serum est...

Increasing Incidence of Premature Thelarche in the Central Denmark Region? Who Evolve into Precocious Puberty?

Somod Mia Elbek , Vestergaard Esben Thyssen , Kristensen Kurt , Birkebaek Niels Holtum

Background: Premature thelarche (PT) may evolve into precocious puberty (PP). The incidence of PP in girls has increased during the last two decades. The epidemiology of PT in the first years of life is less well described.Objective and hypotheses: We aimed to identify 0–6 year old girls referred to paediatric evaluation for PT in order to examine if the number of girls with PT is increasing, and to describe clinical characteristics of the girls wit...

The Endocrine Response to a Gonadotropin Releasing Hormone (GnRH) Test: Establishing a Reference Interval in Healthy Girls below 6 Years of Age

Vestergaard Esben , Somod Mia , Kamperis Kostas , Kastberg Karin , Rittig Soren , Kristensen Kurt , Birkebaek Niels

Background: Premature thelarche and precocious puberty are frequently diagnosed even in girls below 6 years of age. A GnRH test is often included in the diagnostic work up. Interpretation of the GnRH test in girls below 6 years of age is, however, difficult, because the reference interval has not been established in this age group.Objective and hypotheses: To establish the normal endocrine response to a GnRH test in healthy girls below 6 years of age.</p...

Multiple Endocrinopathies in a Case with H Syndrome due to a Novel slc29a3 Mutation

Mutlu Gul Yesiltepe , Kirmizibekmez Heves , Ozsu Elif , Zlotogorski Abraham , Hatun Sukru

Background: H syndrome (OMIM #602783) is an autosomal recessive syndrome resulted from mutations in the SLC29A3 gene, encoding hENT3 protein. Characteristic findings are cutaneous hyperpigmentation, hypertrichosis, hepatosplenomegaly, hypogonadism, hyperglycemia/diabetes mellitus, cardiac anomalies, hallux valgus and short stature. Herein we report a girl with multiple endocrinopathies due to H syndrome.Case: Ten year and 5 month old girl was referred be...

Introduction: Despite existing guidelines there is no unified approach to glucocorticoid and mineralocorticoid replacement in congenital adrenal hyperplasia (CAH). Consequently, treatment varies in adults and children as well as across countries.Objective: We used data from the I-CAH Registry to identify geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of children and adul...

Reproductive hormone levels in Minipuberty as a predictor of Testicular Endocrine Function and Penile Length in Healthy Young Men: An 18-year longitudinal Cohort Study

Henriksen Louise S. , Petersen Jorgen H. , Skakkebaek Niels E. , Jorgensen Niels , Virtanen Helena E. , Juul Anders , Toppari Jorma , Main Katharina M. ,

Background: Minipuberty denotes a period 1–6 months postnatally in boys during which a transient activation of the hypothalamic-pituitary-gonadal axis is observed. This early hormone activation can be used diagnostically in patients suspected of pituitary deficiency and differences in sex development. However, its significance for prediction of reproductive function in healthy young men is unknown.Objective: To eval...

The Correlation between the Increase in IGF1 24 h after the First Injection of GH and the Improved Growth

Miyako Kenichi , Mushimoto Yuichi , Kawano Atsuko

Background: IGF1 is a biomarker of GH, and is often used to titrate the dose of GH therapy. However, IGF1 production is regulated by not only GH but also other factors.Objective and hypotheses: We investigated whether the increase in IGF1 at several time points after the commencement of GH therapy could be a predictive factor for the improved growth.Method: We studied 45 pre-pubertal patients with GH deficiency (GHD) that had conti...

Can Neuroimaging Predict Endocrine Morbidity in Congenital Hypothalamo-Pituitary (H-P) Disorders?

Cerbone Manuela , Guemes Maria , Wade Angie , Improda Nicola , Dattani Mehul T

Background: Few studies have described the phenotypic spectrum of Septo-Optic Dysplasia (SOD). The aim of this study was to evaluate the range of H-P structural abnormalities and the endocrine morbidity of children with SOD and related disorders.Methods: Retrospective longitudinal single centre study of children with SOD (n:171), Multiple Pituitary Hormone Deficiency (MPHD) (n:53) and Optic Nerve Hypoplasia (ONH) (n:35).<p class="ab...

Influence of Salt Supplementation on Drug Therapy in Children with Congenital Adrenal Hyperplasia (CAH) Due to 21-Hydroxylase Deficiency Aged 0-3 Years: Update on a Retrospective Multicentre Analysis Using the I-CAH Registry

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...
