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: 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...

From time to time pediatric endocrinologists may be confronted with paradoxical constellations. Here, we report on a 13-year-old boy with type-1 diabetes. He had polyuria and polydipsia for the previous 2 weeks. Three days before presentation, he got increasingly exhausted and developed recurrent vomiting. At presentation his weight was 41,4 kg (P 25-50) and his height was 154 cm (P 25-50). Initial labs were HbA1c 10.2%, glucose 530 mg/dl, pH 7.15, base excess - 21.1 mmol/l, b...

Introduction: The 3 M- syndrome is a rare autosomal recessive disease, which was named after the three first authors Miller, McKusick and Malvaux. It is characterized by pre- and postnatal disproportionate short stature with micromelia, relative macrocephaly, and radiological bone dysmorphism. It is based on a mutation in one of the three genes CUL7, OBSL1 or CCDC8.Methodology: We report on a meanwhile 4 4/12- year- old girl who presente...

We report a girl born small for gestational age with a birth weight of 1970g. At the age of 2 years she developed marked dystrophy, height was -4.39 SDS and BMI was -3.1 SDS. Later she developed severe insulin restistance and hyperglycaemia due to compound heterozygous mutations in the insulin receptor gene: exon 16: c.2986A>G (paternal) and intron 9: c.2029+1G>T (maternal). Clinical findings included severe acanthosis nigricans, mild hypertrophic cardiomyopathy, abnorma...

Introduction: Neonatal screening has undoubtedly proved its worth in detecting cases of congenital hypothyroidism at an early stage. If there are several affected individuals in a family, this should be a reason to consider a hereditary form and to initiate molecular genetic testing.Case descriptions: the firstborn sister (15 yrs) presented with grossly elevated TSH of 223 mU/ml in neonatal screening and with congenital ...

The Loeys-Dietz-Syndrome is a connective tissue disease, which belongs to the group of Marfanoid syndromes. LDS is classified into 6 different subtypes according to the underlying mutation. All mutations are autosomal dominant inherited. Patients with Loeys-Dietz-Syndromes are characterized from cardiovascular and skeletal malformations, like aneurysms of aorta and other arteries, pectus excavatum, pectus carinatum, chicken- or funnel breast, arachnodactyly clubfoot, scoliosis...

Background: We present the case of an infant with congenital hyperinsulinism presenting with persisting hypoglycaemias.Case Presentation: The boy was born at 37+3 weeks, weighing 4690g (>99. Percentile, Z-score +3.38). Large for gestational age status was suspected throughout pregnancy, gestational diabetes had been excluded via an oral glucose tolerance test twice. The newborn was initially treated at a secondary car...

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: We describe the case of a male newborn, presenting in our outpatient endocrinological clinic after suffering from a bilateral adrenal haemorrhage in the context of a moderate perinatal asphyxia.Case Presentation: The term male newborn was born spontaneously from breech position after a prolonged labour in a secondary care centre in Freiburg, Germany. Perinatal BGA showed severe metabolic acidosis (pH 6.99, BE...
