As Northern Europeans are currently the tallest people in the world, specific growth charts for girls with Turner's Syndrome from this area are needed. Based on height and weight measurements from 598 girls with Turner's Syndrome (372 from the Netherlands, 108 from Denmark, 118 from Sweden) not treated with growth-promoting substances and without signs of spontaneous puberty, we constructed growth charts for height-for-age, height-velocity-for-age, weight-for-age, weight-for-height and Body Mass Index for age. Reference tables and regression equations for mean and standard deviation are provided allowing calculation of Standard Deviation Scores. The height and height velocity curves show a low birth length, gradual deviation from the normal percentile curves without pubertal growth spurt, and a prolonged growth until the early 20s. Mean adult height was 146.9 +/- 7.8 cm. Mean weight-for-age was lower than in normal reference children but height-adjusted weight was higher, except in infancy and early childhood. Further studies are required on the factors influencing the weight-height relationship in Turner's Syndrome.

Long term noninvasive respiratory support, comprising continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV), in children is expanding worldwide, with increasing complexities of children being considered for this type of ventilator support and expanding indications such as palliative care. There have been improvements in equipment and interfaces. Despite growing experience, there are still gaps in a significant number of areas: there is a lack of validated criteria for CPAP/NIV initiation, optimal follow-up and monitoring; weaning and long term benefits have not been evaluated. Therapeutic education of the caregivers and the patient is of paramount importance, as well as continuous support and assistance, in order to achieve optimal adherence. The preservation or improvement of the quality of life of the patient and caregivers should be a concern for all children treated with long term CPAP/NIV. As NIV is a highly specialised treatment, patients are usually managed by an experienced pediatric multidisciplinary team. This Statement written by experts in the field of pediatric long term CPAP/NIV aims to emphasize on the most recent scientific input and should open up to new perspectives and research areas.
