Background: Heterozygous mutations in the Aggrecan gene (ACAN) cause autosomal dominant short stature with bone age (BA) acceleration, and premature growth cessation.Objective and methods: To characterize the phenotypic spectrum, associated conditions and describe response to growth-promoting therapies, detailed clinical evaluation of 73 mutation positive individuals from 16 families different families with heterozygous ACAN mutations was perfor...

Introduction: This was a population-based retrospective data analysis. The study was part of the Vulnerable Newborn Study, approved by the Hamad Medical Corporation Institutional Review Board (IRB No MRC-01-21-277).Setting and Participants: The population for this analysis comprised of a 4-year cohort data (January 2016 to December 2019) for births conducted in all HMC hospitals (representing 90% of all births in the cou...

Background: Knowledge on the role of diabetes antibodies in CF related diabetes mellitus (CFRD) is scarce.Objective and hypotheses: We aim to inquire the relevance of ß-cell autoimmunity in CFRD.Methods: The German/Austrian/Luxembourgian diabetes registry DPV was searched for CFRD patients. 878 individuals were analyzed by multivariable regression models.Results: 8.7% of patients with CFRD in our cohort ...

Background: Maternal bariatric surgery is associated with increased risk of small-for-gestational-age infants. Risk of nutritional deficiencies in neonates of mothers with prior gastric bypass (GBP) is unclear.Methods: This study compared the clinical and cord blood biological characteristics of 56 newborns of GBP mothers and 56 newborns of healthy mothers, in the Obstetrics Department of Angers University Hospital between 01/03/2008 and 31/10/2012. Afte...

Background: It is often difficult to establish whether hyperthyrotropinemia in preterm newborn is a simple physiologic energy sparing phenomenon or a true hypothyroidism requiring replacement treatment.Objective and hypotheses: This study aimed to find in what extent thyroid function in the preterm newborn can be influenced by clinical characteristics and complications.Method: We studied 35 preterm newborn, gestational age (GA) 32....

Cholestatic hepatitis and hypercalcemia are rare features of hypopituitarism in the newborn. So diagnosis of hypopituitarism is frequently delayed. Herein, we report a newborn that was investigated for cortisol deficiency and other pituitary hormone deficiencies and diagnosed with panhypopituitarism upon detection of cholestasis after referral to the endocrinology department for hypercalcemia, a very rare sign of cortisol deficiency. It is unclear which hormone causes cholesta...

Background: Hyperinsulinaemic Hypoglycaemia (HH) is a rare genetic disease and the treatment of HH in cases with unresponsiveness to medical therapy is subtotal pancreatectomy. In a recent study, the authors showed that sirolimus could be an alternative treatment in these patients. We aimed to evaluate the effectiveness of sirolimus in a newborn with HH.Case: A 10 day-old neonate presented with hyperinsulinaemic hypoglycaemia (glucose: 26 mg/dl, insulin:...

Background: POU1F1 encodes a pituitary-specific homeodomain transcription factor that is crucial for development and differentiation of anterior pituitary cell types. Mutations in this gene result in GH, TSH and prolactin (PRL) deficiencies.Objective and hypotheses: To describe a male newborn of a mother with known dominant p.R271W mutation in the POU1F1 gene.Methods: Case report with clinical follow up, endocrine investigations, n...

Background: There is increasing evidence that body composition in early life has both immediate and long-term influence on health. Air-displacement plethysmography creates the opportunity to study the effect of prenatal and early postnatal factors on neonatal body composition. Prenatal maternal factors, such as pre-pregnancy BMI and gestational weight gain, might also influence neonatal body composition.Objective and Hypotheses: We hypothesized that newb...

Introduction: McCune–Albright syndrome (MAS) is a rare disease defined by café-au-lait spots, gonadotropin-precocious puberty and fibrous dysplasia. It could be associated with others endocrinopathies: thyroid involvement as a common feature. The prevalence is very low, being outstanding the neonatal diagnosis, especially in males.Case presentation: A male term newborn with a café-au-lait extensive spot involving the back, arms, legs and s...
