Background: The prevalence of hyperthyroidism in pregnancy is about 0.2%, mostly due to Graves disease. Neonatal autoimmune hyperthyroidism caused by the transplacental passage of stimulatory thyrotropin receptor antibodies (TRAB) of the IgG class is a rare disorder. It occurs in only 2% of the neonates of mothers with Graves disease, is transient and associated with high morbidity and mortality rates up to 25%. Antithyroid drugs are the treatment ...

Background and Aim: Achondroplasia is the most common skeletal dysplasia and is associated with serious complications such as foramen magnum stenosis (FMS). Current guidelines in Germany recommend polysomnography at 2-3 months and cranial imaging at 6-9 months of life in achondroplasia, whereas American Academy of Pediatrics recommends to evaluate every infant with achondroplasia for cranio-cervical junction risks via neurologic examination, polysomnography an...

Background: PTEN Hamartoma Tumor Syndrome (PHTS) encompasses different syndromic disorders which are associated with autosomal-dominant mutations of the tumor suppressor gene PTEN. Patients are at high risk to develop benign and malignant tumors. Macrocephaly is a diagnostic feature, but there is a paucity of data on prevalence, degree und development during growth. Charts for length, weight and head circumference for this rare disorder do no...

Background: Donohue syndrome (DS) is caused by autosomal-recessive loss of function mutations of the insulin receptor gene. DS is associated with diabetes mellitus unresponsive to conventional insulin therapy due to severe insulin resistance. Patients exhibit IUGR and postnatal failure to thrive. They develop a characteristic facies, hypertrichosis and acanthosis nigricans. Most patients die within the first two years of life because of respiratory infections. To date, no caus...

Background: A 6-week-old male was admitted for investigation of prolonged jaundice. The pregnancy was unremarkable with a normal at term delivery. The neonatal screening was unremarkable. The boy was born to consanguineous parents of Turkish descent.Objective and hypotheses: At presentation serum levels of thyrotropin, T4 and T3 were low and prolactin slightly elevated. Venous TSH was undetectable low. Central hypothyroidism was dia...

Bacterial infection of the thyroid gland (acute suppurative thyroiditis, AST) is a very rare condition, particularly in children, as the thyroid gland is extremely resistant to infection. AST presents with painful tender mass in the anterior neck and is usually associated with fever, sore throat, dysphagia and limitation of the neck movements. In the most cases the left globe is affected. Common laboratory findings are leukocytosis, elevated erythrocyte sedimentation rate (ESR...

Background: Achondroplasia (Ach) is a rare growth disorder caused by a point mutation in the fibroblast growth factor receptor 3 gene that results in dysproportionate extreme short stature and can lead to a wide range of multisystemic complications throughout the individual's life with reduced quality of life. In the past, orthopaedic and neurosurgical therapies have been developed to partially improve mobility, reduce pain and prevent neurological disabi...

Aim and background: Growth hormone (GH) treatment of short children born SGA and its effects on growth varies greatly between treated individuals. In the present study we tested the performance of a preexisting growth prediction model (Ranke et al.; JCE&M 2003 pp. 125–131) to estimate 1st-year height velocity (HV) in a german subcohort of prepubertal children born SGA treated with GH (Omnitrope).Methods: 190 treatment-naïve prepu...

Background: Quality management of GH treatment in children is important to ensure optimal treatment outcome and to save resources in the health care system. iGRO is a new internet based Medical Device to compare treatment results with predicted results according to published prediction models.Objective and hypotheses: Growth data were analyzed by iGRO for 1st and 4th year prediction in comparison to treatment results. All eligible patients of our practic...

Background: In contrast to monogenic diseases, contiguous gene syndrome (CGS) describes a clinical phenotype caused by a deletion or duplication of several neighbouring genes. Angelman or Williams-Beuren syndrome are examples demonstrating that deletion of several adjacent genes causes a complex clinical syndrome. However, CGS are very rare events in pediatric endocrinology, and require knowledge of clinical associations pointing towards specific potentially affected genes in ...
