Rhabdomyosarcoma (RMS), a tumor of skeletal muscle origin, is the most common sarcoma of childhood. Despite multidrug chemotherapy regimens, surgical intervention, and radiation treatment, outcomes remain poor, especially in advanced disease, and novel therapies are needed for the treatment of these aggressive malignancies. Genetically engineered oncolytic viruses, such as herpes simplex virus-1 (HSV), are currently being explored as treatments for pediatric tumors. M002, an oncolytic HSV, has both copies of the γ134...

OBJECTIVES: Respiratory symptoms are a possible atypical clinical picture of gastro-esophageal reflux disease (GERD). However, a significant number of patients with GERD-related respiratory symptoms do not report improvement despite aggressive acid-suppressive therapy. Some of these refractory cases may be due to the recently appreciated entity of non-acid or weakly acidic reflux. The aim of our study is to assess the pH-impedance features of GER inducing airway symptoms, compared with GER inducing typical gastro-intestinal (GI) symptoms...

There is no general consensus regarding which accelerometer cut-off point (CoP) is most acceptable to estimate the time spent in moderate-to-vigorous physical activity (MVPA) in children and choice of an appropriate CoP primarily remains a subjective decision. Therefore, this study aimed to analyze the influence of CoP selection on the mean MVPA and to define the optimal thresholds of MVPA derived from different accelerometer CoPs to avoid overweight/obesity and adiposity in children aged 7 to 12 years. Three hundred six children participated...

Metallo-phthalocyanines due to their photophysical characteristics as high yield of triplet state and long lifetimes, appear to be good candidates for photodynamic therapy (PDT). Complexes with diamagnetic metals such as Zn2+, Al3+ Ga3+ and In3+meet such requirements and are recognized as potential PDT agents. Clinically, Photofrin® PDT in neuroblastoma therapy proved in pediatric subjects diagnosed with progressive/recurrent malignant brain tumors increased progression free survival and overall survival outcome...

BACKGROUND: Wound healing is a dynamic process that normally follows a predictable cascade of events. A common cause of delayed wound healing or wound dehiscence is increased colonization with microbes, often leading to infection. Infection may impede the healing process by inducing an undesirable inflammatory response. Systemic antibiotics and topical antiseptics are mainstays of treatment, but their adverse side effects and the potential for emergence of resistant microbial strains have led to a search for alternative approaches for control of bioburden...

BACKGROUND: Pepsin in saliva is a proposed biomarker for oropharyngeal reflux. Pepsin may be prevalent in saliva from subjects with gastro-esophageal reflux and may correlate with proximal reflux by intraluminal impedance/pH monitoring (MII/pH). METHODS: Patients (3 days to 17.6 years, n=90) undergoing 24-hour MII/pH monitoring and asymptomatic controls (2 months to 13.7 years, n=43) were included. Salivary pepsin was determined using a pepsin enzyme-linked immunosorbent assay...

OBJECTIVES: To determine which objective pressure-impedance measures of pharyngeal swallowing function correlated with clinically assessed severity of oropharyngeal dysphagia (OPD) symptoms. STUDY DESIGN: Forty-five children with OPD and 34 control children without OPD were recruited and up to 5 liquid bolus swallows were recorded with a solid-state high-resolution manometry with impedance catheter. Individual measures of pharyngeal and upper esophageal sphincter (UES) function and a swallow risk index composite score were derived for each swallow, and averaged data for patients with OPD were compared with those of control children without OPD...

AIMS AND OBJECTIVES: The aim of this study was to explore the factors contributing to the low physical activity level for Hong Kong Chinese children hospitalized with cancer. BACKGROUND: Notwithstanding the fact that regular physical activity can ameliorate cancer-related fatigue and other adverse effect of cancer treatment on children's physical and psychological well-being, physical inactivity is a common problem among children undergoing cancer treatment. Understanding the factors which affect their physical activity level is an important step toward planning and evaluating an appropriate intervention that promotes the adoption and maintenance of regular physical activity...

PURPOSE: To investigate the effects of mild-to-moderate cystic fibrosis (CF) on the pulmonary oxygen uptake (V˙O2) kinetics of 7 pediatric patients (13.5 ± 2.8 y) versus 7 healthy matched controls (CON; 13.6 ± 2.4 y). We hypothesized that CF would slow the V˙O2 kinetic response at the onset of moderate (MOD) and very heavy (VH) intensity cycling. METHODS: Changes in breath-by-breath V˙O2, near-infrared spectroscopy-derived muscle deoxygenation ([HHb]) at the m...
