Treatment of pediatric spasticity, including children with cerebral palsy, with Botox (onabotulinumtoxinA): Development, insights, and impact.

Spasticity is a velocity-dependent increase in muscle tone that has a negative effect on quality of life and hinders the ability of others to provide care. In children, most cases are caused by cerebral palsy. Traditionally, many children are treated with surgery, sometimes performed before their limbs had grown sufficiently to permit long-term success.

Willingness to vaccinate children against COVID-19 declined during the pandemic.

Objectives: To document the level of vaccine hesitancy in caregivers' of children younger than 12 years of age over the course of the pandemic in Pediatric Emergency Departments (ED). Study design Ongoing multicenter, cross-sectional survey of caregivers presenting to 19 pediatric EDs in the USA, Canada, Israel, and Switzerland during first months of the pandemic (phase1), when vaccines were approved for adults (phase2) and most recently when vaccines were approved for children (phase3).

Results: Willingness to vaccinate rate declined over the study period (59.

Usefulness of Calcium Scoring as a Screening Examination in Patients With a History of Kawasaki Disease.

Subsets of patients with a remote history of Kawasaki disease (KD) have coronary artery aneurysms with associated risks of late morbidity. In a pilot study, we previously showed that computed tomography (CT) coronary artery calcium (CAC) scoring detects late CAC in patients with aneurysms and a remote history of KD. We performed CT calcium volume scoring in 166 subjects (median age 19.

Transforming growth factor-beta signaling pathway in patients with Kawasaki disease.

Background: Transforming growth factor (TGF)-β is a multifunctional peptide that is important in T-cell activation and cardiovascular remodeling, both of which are important features of Kawasaki disease (KD). We postulated that variation in TGF-β signaling might be important in KD susceptibility and disease outcome.

Methods And Results: We investigated genetic variation in 15 genes belonging to the TGF-β pathway in a total of 771 KD subjects of mainly European descent from the United States, the United Kingdom, Australia, and the Netherlands.
