Should We Construct Specific Growth Charts for Ethnic Subgroups?

Pop Raluca-Monica , Pascanu Ionela Maria

Background: Romania has a 3.3% Rromanes population according to the latest census, but no specific growth charts for this ethnic minority. Current national protocol recommends using the Swiss growth charts developed in 1989. Specific growth charts exist for ethnic subgroups like Turks in Germany and the Netherlands.Objective and hypotheses: A comparison between a Rromanes and a Romanian group of children regarding weight and height disturbances’ pre...

Aetiology of Congenital Hypoadrenalism

Achermann John

Congenital adrenal insufficiency is a potentially life-threatening condition that can present soon after birth in many different ways. The classic presentation is a salt-losing crisis due to mineralocorticoid insufficiency, often between a week and two of life, but babies with predominant glucocorticoid insufficiency can present with other features such as prolonged jaundice, hypoglycaemia and hyperpigmentation. Most children with congenital adrenal insufficiency present to em...

Early Medical Treatment of Children with Gender Dysphoria: an Empirical Ethical Study on Arguments of Proponents and Opponents Concerning Early Interventions

de Vries Martine , Vrouenraets Lieke , Wichmann Anne , Schermer Maartje , Fredriks Miranda , Delemarre-van de Waal Henriette

Background: Both The Endocrine Society and the World Professional Association for Transgender Health (WPATH) published guidelines for the treatment of children and adolescents with gender dysphoria (GD). The guidelines recommend the use of GnRH agonists in adolescence to suppress puberty, and the use of cross-sex hormones starting around age 16 for eligible patients. In actual practice, there is no consensus whether to use these early medical interventions. The aim of our stud...

Background: Deficiency of 11β-hydroxylase is the second most frequent type of congenital adrenal hyperplasia and more common in Turkey than other populations.Objective and hypotheses: The purpose of this study is to examine the spectrum of CYP11B1 gene mutations in Turkish population.Method: 17 patients from 13 families are included in this study. Diagnosis was based on virilisation and high levels of 11-deoxycortisol. 15 case...

Background: Homozygous natriuretic peptide receptor-2 (NPR2) mutations cause acromesomelic dysplasia, type Maroteaux, a skeletal dysplasia with extreme disproportionate short stature and recently, heterozygous NPR2 mutations have been identified also in patients with idiopathic short stature (ISS, 2–6%). SHOX mutations are found in ~2–5% of ISS cases and ~70% of Léri-Weill dyschondrosteosis (LWD) cases, characterized by disproportionat...

46XY, DSD due to 5α-Reductase Type 2 Deficiency in 19 Chinese Patients

Li Yan-Hong , Du Min-Lian , Ma Hua-Mei , Chen Hong-Shan , Chen Qiu-Li

Background: Patients with 46,XY, DSD are characterized by ambiguous or female external genitalia, caused by incomplete intrauterine masculinization. 5α-reductase type 2 deficiency due to SRD5A2 gene mutations result in inadequate conversion from testosterone to dihydrotestosterone (DHT), and is responsible for incomplete virilization in male patients. Up to date, more than 50 mutations have been reported, however, clinical features are variable and heterogeneous.<p cl...

Sundaram Janani , Prasad Hemchand Krishna , Murugesan Gnanabalan , Vasudevan Ravisekar , Sangaralingam Thangavelu

Background: Basal or unstimulated hormone levels frequently do not provide sufficient diagnostic information in the investigation of endocrine disorders. A range of dynamic or provocative tests are available to assess the dynamic responses of hormones and make necessary diagnoses.Objective and hypotheses: To describe the experiences with dynamic stimulation testing of a Paediatric Endocrine Unit in a developing country.Method: Retr...
