Background: Infants with severe insulin resistance syndrome show failure to thrive.Objective and hypotheses: Effect of rhIGF1 treatment on growth in a patient with severe insulin resistance syndrome.Method: Case report.Results: The patient is a 4-years-old Caucasian girl of unrelated healthy parents. She was born after a 40 weeks gestation as a small for gestational age infant with a birth weight of 1970 g. A...

Background: At present, treatment of „classic" congenital adrenal hyperplasia (21-hydroxylase-deficiency, 21OHD) consists of glucocorticoid and mineralocorticoid replacement. However, often androgen excess and its negative metabolic impact are difficult to control without accepting glucocorticoid overtreatment, especially in adolescence. In healthy subjects oral contraceptives (containing ethinylestradiol) increase cortisol binding capacity and free c...

Background: Monitoring treatment of children with classic congenital adrenal hyperplasia (CAH) is difficult and biochemical targets are not well defined.Objective and hypotheses: To analyse the urinary steroid metabolome of children with classic 21-hydroxylase deficiency (21-OHD) during treatment with hydrocortisone and fludrocortisone.Method: We retrospectively analysed 553 daily urinary steroid hormone metabolite profiles determi...

Background: One major issue of newborn screening programs for 21-hydroxylase deficiency (21OHD) is the high rate of false-positive results, especially in preterm neonates. Urinary steroid analysis using gas chromatography–mass spectrometry (GC–MS) is used as a confirmatory diagnostic tool.Objective and Hypotheses: The objective of this study was to analyze diagnostic metabolite ratios in neonates and infants with and without 21OHD using GC&#150...

Background: For a few years now tubeless disposable patch pumps are available for insulin therapy.Objective and hypotheses: Alarmed by initially non explainable beginning metabolic decompensation of two children with type 1 diabetes during their hospital stay for the initial therapy adjustment with patch pumps and alarmed by patients’ reports of frequent premature pump changes and alarms, we decided to scrutinize the patch pumps under laboratory con...

Background: Working as a physician is accompanied by emotional and physical stress.Objective and hypotheses: Our study aimed to investigate the effect of working day and night in a children’s hospital on catecholamine excretion as a marker for acute stress and to work out possible gender differences.Methods: 22 paediatricians (ten females, 12 males) aged 27–41 years collected four 12-h urine samples: two during a 24 h-shi...

Background: Hashimoto’s thyroiditis (HT) is an autoimmune-mediated disorder, and is the most common cause of thyroid disease and acquired hypothyroidism in children and adolescents. In adults with HT, concentration problems, memory disorders and an increased rate of depression have been reported.Objective and hypotheses: To investigate, whether children and adolescents with HT have more behaviour and emotional problems, and/or lower intelligence tha...

Background: Steroid responsive encephalopathy with autoimmune thyroiditis (SREAT) is a clinically and electrographically heterogeneous steroid-responsive encephalopathy associated with thyroid autoantibodies.Objective and hypotheses: To investigate, whether children and adolescents with Hashimoto’s Thyroiditis (HT) lacking acute clinical manifestation of SREAT show electroencephalogram (EEG) alterations, and to compare EEGs of HT patients with those...

Background: Therapy in type 1 diabetes has undergone a fundamental change over the last several decades, especially by the use of technical devices. Another change that took place is the growing awareness of sex differences of all kind, e.g. as influencing factors of metabolic control. Our study aimed to evaluate sex differences over two decades with regard to changes in glycaemic control, with regard to trends in insulin pump use and insulin dose. Migration b...

Background: P450 oxidoreductase (POR) mutations can present with disordered sexual development (46,XX virilisation as well as 46,XY under-masculinisation), perturbed steroidogenesis and mild to severe skeletal malformations. As POR is an obligate electron donating cofactor to many P450s, and as this interaction may vary from partner to partner, the phenotypic spectrum of PORD is extremely broad. Therefore, to characterize novel POR mutations, specific testing is required.<...
