A rare case of 46,XY difference of sexual development (DSD) due to combined homozygous CYP17A1 and heterozygous CYP21A2 mutations with a unique phenotype and hormone profile

Aikaterini Stasinaki , Sarah Oberhauser , Dagmar l'Allemand-Jander

Background: 17a-hydroxylase/17,20-lyase deficiency is a rare cause of congenital adrenal hyperplasia (CAH). 46,XY infants may present with ambiguous genitalia. Adrenal crises are rare due to compensatory glucocorticoid action of the overproduced corticosterone.Case: A 3-month-old boy underwent a complication-free externalization of concealed penis and circumcision by a paediatric surgeon. At the age of 2.5 years, the boy...

Pedigree analysis is essential for clarifying oligogenic transmission in a family with congenital hypogonadotropic hypogonadism (CHH)

Oberhauser Sarah , Papadakis G Georgios , Pitteloud Nelly , L’Allemand Dagmar ,

Background: Congenital hypogonadotropic hypogonadism (CHH) is a rare disease with a complex clinical picture and genetic background. In up to 50% genetic mutations are found. The goal is to be able to provide a comprehensive prognosis and genetic counseling for this family with CHH.Case presentation: At the age of 16 years a boy with familial constitutional delay (adrenarche only with 15 years, no growth spurt, bone age 14 years) present...

Peripheral nerve conduction velocity in children and young adults with type 1 diabetes mellitus as a marker of metabolic control

Oberhauser Sarah , l'Allemand Dagmar , Heldt Katrin , Gozzi Tiziana , Stasinaki Aikaterini , Eilers Miriam , Lütschg Jürg , Broser Philip

Background: Nerve conduction velocity (NCV) abnormalities are considered as early signs of peripheral neuropathy in patients with diabetes mellitus (DM). We investigated which determinants NCV is subject to and how it is related to markers of metabolic control.Methods: We included 51 patients treated at the outpatient clinic of paediatric diabetology because of their type 1 DM and randomly assigned them for a nerve condu...

Background: There is an urgent need for better detection of early subclinical manifestations of microvascular complications of diabetes such as peripheral neuropathy (DPN), which already occur in children. The gold standard for the diagnosis of DPN is the measurement of nerve conduction velocity (NCV), which, however, can only detect changes in the large myelinated fibres. At the initial stage of DPN, small, unmyelinated nerve fibres are damaged. High-resoluti...
