A study of the efficacy and safety of Lubiprostone in pediatric subjects aged ≥ 6 Years to < 18 years diagnosed with Functional Constipation

Idiopathic Toe Walking (ITW) is a diagnosis normally of exclusion and likely, consequently, is approached in vastly varying ways of intervention, including serial casting, Botox injections and physical therapy. There is some evidence in the literature that children with ITW can somewhat correct their lack of heel-strike gait pattern at least temporarily. Kinesio Taping (KT) method is an intervention that is used in the outpatient physical therapy setting for various conditions such as post-operative edema, muscle facilitation of weakened rotator cuff muscles, and functional corrections in children with torticollis. This pilot study will strive to determine if KT may be ...

Neonates and infants that have cardiac surgery with cardiopulmonary bypass (CPB) for congenital heart disease are at great risk for experiencing life-threatening low cardiac output syndrome (LCOS) in the first 24 hours after surgery. The poor perfusion and inadequate oxygen delivery that occurs may result in multiple organ failure and death. It is LCOS that is responsible for the majority of early postoperative deaths in this population of neonates and infants. Improved pediatric probes placed in peripheral locations using near infrared spectroscopy (NIRS) may permit continuous monitoring of venous saturations reflecting overall perfusion and oxygen balance in the tissues. Following ...
