Filter by:This study evaluates the therapeutic effects of hippotherapy in children with Prader-Willi syndrome. Half of children will participate in hippotherapy for 15 weeks (30 minutes per sessions, twice a week, total 30 sessions, private lesson), while the other half will not receive hippotherapy.
To evaluate the effectiveness of rhGH (Recombinant human growth hormone) injection for improving motor development in patients with PWS.
This study is a phase 2 randomized double blind 8-week treatment trial of intranasal OXT vs. placebo in 50 subjects aged 5 to 17 years with PWS in order to assess IN-OXT's affect on measurements of (1) eating behaviors (2) repetitive behaviors (3) weight and body composition (4) quality of life (5) salivary OXT and hormone levels (including ghrelin, pancreatic polypeptide, peptide YY, GLP-1, insulin, glucagon, testosterone, and estrogen). If superior to placebo, this data will add to the current knowledge that OXT is an effective treatment for hyperphagia as well as other symptoms of PWS. Funding Source- FDA OOPD
The aim of this study is to determine if treatment with Medical Air (21% oxygen in room air) compared to supplemental oxygen (100% oxygen) will lead to similar improvements in the central apnea-hypopnea index (CAHI) for infants with Prader-Willi Syndrome. Despite the vast amount of research investigating the cause of central sleep apnea, there remain gaps in knowledge, lending to further research efforts. The decision to compare oxygen to medical air is based on several theorized mechanisms. The first of which is the supposition that provision of medical air may act as an arousal stimulus for the hypothalamus, thereby preventing sleep disordered breathing. Secondly, the hypercapnic challenge performed by Livingston et al demonstrated a delayed hypercapneic arousal response in PWS subjects despite simultaneous hyperoxia, leading us to question if therapeutic oxygen really plays a significant role in treating CSA. Lastly, the delivery of medical air via nasal prongs may provide sufficient arousal to terminate the cycle of events leading to central apnea, as described by Urquhart et al. A deeper understanding of central sleep apnea is essential to ameliorating its adverse sequelae, which include symptoms of ADHD, impaired attention, behavioral problems, and academic difficulties.
Prader-Willi Syndrome (PWS) is a rare syndrome with a prevalence of 15 to 20 000 at birth. PWS represents a large fraction of mental retardation syndromes due to a genetic cause and the most frequent cause of genetic obesity. The majority of the patients are seen by paediatricians. This syndrome is responsible for severe physical, psychological and social impairments. The diversity and the severity of the manifestations of this disease explain the requirement of multidisciplinary care which deserve specific evaluation. Today the follow-up and management of a great proportion of these patients are greatly insufficient if not absent. Teams strongly lack information on the natural history of this severe disease and on the factors involved in its evolution and the outcome of these patients throughout life. The present project is to implement a register in the whole country for children and adult patients
The purpose of this study is to investigate the safety and efficacy of deep brain stimulation in obese patients with Prader Willi syndrome refractory to conventional treatment.
Compared to other children, those with disability have additional challenges to being physically active. Prader-Willi Syndrome (PWS) is a genetic form of childhood obesity that is characterized by hypotonia, growth hormone deficiency, behavioral, and cognitive disability. In children, the low prevalence of PWS (1 in 10,000 to 15,000 live births) makes group-based physical activity (PA) interventions impossible. In contrast, the home environment presents a natural venue to establish a PA routine for this population. The present high prevalence of non-syndromal childhood obesity (one in four) and high physical inactivity rates, make alternative approaches to increasing PA in this population an area of high interest. Therefore, we have developed a 24-week home-based physical activity that could be suitable for children and adolescents ages 8-15 with PWS as well as obese children without PWS ages 8-11 years. It is hypothesized that: 1) an age-appropriate 24-week home-based PA intervention will increase PA levels in youth with PWS and without the syndrome but with obesity; 2) motor proficiency, central sensory reception and integration, and body composition will significantly improve in youth with and without PWS following completion of the home-based PA intervention and 3) physical activity self-efficacy and quality of life will increase significantly in youth with and without PWS who complete the home-based PA intervention. The study participants are 115 youth ages 8-15 y (45 with PWS and 70 without PWS but categorized as obese). The study utilizes a parallel design with the wait-listed control group receiving the intervention after serving as control. Participants are expected to complete the PA curriculum 4 days a week for six months including playground games 2 days a week and interactive console games 2 days a week. Parents are trained at baseline and then provided with a PA curriculum (Active Play at Home) and equipment to guide their implementation of the program at home. Measurements of children and parent dyads are assessed at baseline and at the end (week 24) of the intervention or control periods. Outcome measures include PA, body composition, motor proficiency, central sensory reception and integration (subsample of children only), quality of life and physical activity self-efficacy. PA intervention compliance is monitored using mail-in daily self-report checklists.
