Development of a Parent Experience Measure for Parents of Children with Achondroplasia

Pfeiffer Kathyrn M. , Brod Meryl , Viuff Dorthe , Ota Sho , Gianettoni Jill , Leff Jonathan

Background: Limited research exists on how having a child with achondroplasia impacts parents' daily lives and well-being. The purpose of the study was to gather qualitative evidence to support the development of a parent experience measure that assess the impacts of having a child aged 2 to <12 years with achondroplasia.Methods: Concept elicitation interviews via individual telephone calls and an in-person focus...

A Nationwide Study of the Prevalence & Initial Management of Atypical Genitalia & Delayed Sex Assignment in the Newborn

Rodie Martina , Ali Salma , Jayasena Arundathi , Al-Enazi Naser , McMillan Martin , Cox Kathyrn , Cassim Sumaiya M. , Henderson Stuart , Ahmed S.Faisal

Background: The prevalence of atypical genitalia and the time taken to assign sex in such cases remains unclear. Provision of optimum healthcare during this period requires a clear understanding of the occurrence of atypical genitalia.Methods: Prospective electronic survey of clinical members of managed clinical networks in Scotland between 2013 and 2018 seeking notification of term neonates requiring specialist input fo...

A unique combination of Klinefelter syndrome and Three M Syndrome in a boy with short stature

Lee Mi-Seon , Lee Rosie , Lee Sang-Eun , Kwak Na-eun , Kwon Soon-Hak , Moon Jung-Eun

Introduction: Klinefelter syndrome (KS) is most common sex chromosomal aneuploidy in males. The typical clinical features are tall stature with long extremities, small testis, and learning disabilities. Three M syndrome is an extremely rare genetic disorder characterized by short stature, craniofacial abnormality and skeletal malformations. We report a unique case of short stature in KS due to three M syndrome.Case: A 9-...

Development of a Measure for the Impacts of Achondroplasia on Children's Daily Functioning and Well-Being

Pfeiffer Kathryn M. , Brod Meryl , Viuff Dorthe , Ota Sho , Gianettoni Jill , Leff Jonathan

Background: Research on the impacts of achondroplasia on children's functioning and well-being is limited. The purpose of the study was to investigate the impacts of achondroplasia on children's daily lives to support the development of an impact measure of achondroplasia on children's functioning and well-being.Methods: Individual telephone interviews and one parent focus group were conducted in the United S...

Background: Primary ovarian insufficiency (POI) is genetically mediated in up to 30% of cases. Many genes associated with POI have roles in early ovary developmental processes, including meiosis.Objectives: We investigated the genetic mechanism underlying early-onset POI in three young women presenting with absent puberty: two sisters from a consanguineous pedigree and a third unrelated proband.<st...

Background: Persistent Müllerian duct syndrome (PMDS) is a Disorder of Sex Development (DSD) caused by mutations in genes encoding anti-Müllerian hormone (AMH) or its type II receptor (AMHR2) with autosomal recessive transmission. Objective: To report a case of transverse testicular ectopia (TTE), associated with PMDS, initially presented as an obstructed inguinal hernia.Case presentation: An 18- days- old male infant, wi...

Diagnostic precision of the Tri-Ponderal Mass Index (kg/m3) to identify the metabolic risk phenotype in obese children and adolescents.

Arciniegas Larry , Tomasini Rosangela , Vega Elizabeth , Fabregas Ana , Clemente Maria , Yeste Diego ,

Introduction: The metabolically healthy obese phenotype (MHOF) defines obese patients who have preserved insulin sensitivity and who do not have metabolic complications: lower risk of cardiovascular disease and type 2 diabetes in adulthood. Recent studies indicate that TMI (kg/m3) estimates the percentage of body fat more accurately than the BMI and it has been proposed to substitute the use of the BMI z-score values by those of the TMI. TMI values ...

Specific Hypothalamic Activation Pattern by mGlu5 Receptor Blockade in vivo During Pubertal Development in Female Mice

Inta Ioana , de Angelis Roberto , Lankisch Katja , Dormann Christof , Pfeiffer Natascha , Boehm Ulrich , Gass Peter , Bettendorf Markus

Background: Puberty is characterised by important changes of brain networks. The glutamate system plays a main role in modulating the onset of puberty as shown for NMDA receptor agonists. However, the underlying mechanisms are poorly understood. Metabotropic mGlu5 receptors (mGluR5) are tightly linked to NMDA receptors. The effect of mGluR5 blockade on neurohormonal mechanisms in puberty initiation were not studied yet.Objective and hypotheses: To invest...

Diagnostic accuracy of Tri-Ponderal mass index (kg/m3) for identifying glucose intolerance in obese children and adolescents.

Arciniegas Larry , Mogas Eduard , Tomasini Rosangela , Fabregas Ana , Clemente Maria , Yeste Diego ,

Introduction: The identification of obese patients with increased susceptibility and risk for glucose intolerance and type 2 diabetes requires an oral glucose tolerance test (OGTT). Reference values for Body mass index (BMI) and Tri-Ponderal mass index (TMI) according to age and sex of healthy children in Spain without malnutrition or obesity have recently been published (*). TMI values remain very uniform in both boys and girls from the age of 8 to 18 years, ...

Poor Weight Gain in Prader-Willi Syndrome – Not Always Over-restriction Consider Coeliac Disease

Lateva M , Kassim A , Meade C , Maher R , McCrann A , Roche E

Introduction: Prader-Willi Syndrome (PWS) is a complex genetic condition associated with feeding difficulties, hypotonia, developmental delay in infancy; hyperphagia leading to extreme obesity, growth failure and behavioral problems in childhood. Coeliac disease (CD), is an autoimmune disease characterized by gluten intolerance and a variety of symptoms most commonly diarrhea or constipation and failure to thrive. In PWS the challenge is to optimize growth while avoiding obesi...
