Children and Adolescents with Severe TBI can Develop Late Pituitary Dysfunction Independently of the Results of the First Pituitary Evaluation

Dassa Yamina , Claire Personnier , Helene Crosnier , Mathilde Chevignard , Marie Bourgeois , Magali Viaud , Michel Polak

Background: Traumatic brain injury (TBI) is common in childhood and can induce pituitary defects. Long-term endocrine consequences are missing.Objective and hypotheses: To determine in a prospective way if pediatric patients with a personal history of TBI developed long term pituitary deficiency independently of the results of the early hormonal investigation.Method: Prospective follow-up of an initial cohort of subjects (0–15...

Genetics of Thyroid Dysgenesis and Associated Malformations

Polak Michel

Thyroid dysgenesis (TD) is the most common cause of congenital hypothyroidism in iodine sufficient regions. TD includes a broad spectrum of developmental anomalies varying from absence of thyroid (athyreosis) to an abnormally located thyroid (ectopy), small (hypoplasia) or asymmetric thyroid. Thyroid dysgenesis is usually sporadic, but up to 2% of cases is familial. Genetics of TD is complex and advances in developmental biology over the past two decades revealed monogenetic f...

The Pros and Cons of Using Sulfonylurea before Genetic Testing in Neonatal Diabetes Mellitus

Polak Michel

Background: Very early onset diabetes mellitus (neonatal diabetes mellitus (NDM)) seems to be unrelated to autoimmunity in most instances. A number of conditions are associated with NDM, some of which have been elucidated at the molecular level. Among these, the recently elucidated mutations in the KCNJ11 and ABCC8 genes, encoding the Kir6.2 and SUR1 subunit of the pancreatic KATP channel involved in regulation of insulin secretion, account for one...

Update on the consensus on Congenital Hypothyroidism: a patient-centered approach

Polak Michel ,

Background: An ENDO-ERN initiative was launched which was endorsed by the European Society for Pediatric Endocrinology and the European Society for Endocrinology with 22 participants from the ENDO-ERN and the two societies. The aim was to update the practice guidelines for the diagnosis and management of congenital hypothyroidism (CH). A systematic literature search was conducted to identify key articles on neonatal screening, diagnosis and management of prima...

Objective: Craniopharyngioma is a benign brain tumour with frequent local recurrence after treatment. Growth hormone replacement therapy (GHRT) is prescribed in children with growth hormone deficiency due to childhood-onset craniopharyngioma. The objective was to evaluate whether shorter time delay of GHRT initiation after childhood-onset craniopharyngioma completion therapy increased the risk of recurrence.Design: Our r...

Safety and Effectiveness of Increlex® Therapy in Children with Laron Syndrome and Enrolled in the European Increlex® Growth Forum Database in Europe

Bang Peter , Polak Michel , Woelfle Joachim , Houchard Aude , Sert Caroline

Background: The post-authorisation registry, European Increlex® Growth Forum Database (EU-IGFD), initiated in December 2008, collects data in children receiving Increlex (mecasermin (rDNA origin) injection) for growth failure, including Laron syndrome (LS) (severe primary IGF1 deficiency with confirmed GH-receptor mutation).Objective and hypotheses: Report safety and effectiveness data in children with LS.Method: Multicentre, ...

Adult Height in Children Born Small for Gestational Age and Treated with GH: Data from the French KIGS Database

Polak Michel , Czernichow Paul

Background: Treatment with GH in children born small for gestational age (SGA) increases height velocity (HV) but data on adult height (AH) are scarce.Objective and hypotheses: To report AH in a group of SGA children treated with GH.Method: This is a post-marketing longitudinal analysis of SGA children treated with GH and included in France in KIGS. Selection criteria were children followed at least one year and having reached AH b...

Identifying several patient-related factors that predicted permanent growth hormone deficiency (GHD)

Mericq Veronica , Kariyawasam Dulanjalee , Iñiguez German , Polak Michel

GHD is the most common endocrine disorder in children with short stature (~1 in 4000). Appropriate diagnosis should synthesize auxological, biochemical and neuroradiological data. However, until now there are significant controversies, especially from the laboratory interpretation. A false positive diagnosis can lead to a significant wasted expenditure and unnecessary exposure to rare potential adverse effects. Given these open issues about biochemical diagnosis of GHD in chil...
