PURPOSE Desmoplastic small round cell tumors (DSRCTs) are rare aggressive neoplasms that frequently present with large symptomatic intraabdominal masses. We examined the effects of multimodal therapy including induction chemotherapy, aggressive surgical debulking, and external beam radiotherapy on patients with DSRCT. METHODS Institutional Review Board(More)
OBJECTIVE Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare müllerian anomaly consisting of uterine didelphy, hemivaginal septum, and ipsilateral renal agenesis. The purpose of this study was to evaluate the natural history and outcome of patients with HWWS. METHODS With ethics review board approval, all patients with uterine/vaginal anomalies were(More)
Neuroblastoma is a heterogeneous disease with variable clinical behaviors. Unique molecular features are associated with clinically relevant subgroups. We performed a comprehensive microarray gene expression analysis of 95 neuroblastomas in an effort to define clinically important molecular subtypes. A subset of tumors overexpressed several contiguous genes(More)
BACKGROUND AND PURPOSE Serious treatment-induced esophageal strictures and tracheoesophageal fistulae are rare in the pediatric oncology population. This report details our experience with their management. METHODS We retrospectively reviewed our experience with pediatric oncology patients treated for esophageal complications over a 23-year period.(More)
PURPOSE All-terrain vehicle (ATV)-related injuries continued to increase in recent years. We aimed to analyze the ATV injury patterns at our institution to help structure public awareness campaign and encourage governmental regulation, with the ultimate goal of injury prevention. METHODS A retrospective review of all ATV-related admissions at a pediatric(More)
PURPOSE Gastroesophageal reflux (GER) is observed in 22% to 81% of neonates with congenital diaphragmatic hernia (CDH). The purpose of this study was to identify factors that may predict GER requiring fundoplication in neonates with CDH. METHODS A retrospective chart review was performed on all neonates with CDH treated at our hospital from June 1997 to(More)
BACKGROUND/PURPOSE The timing and need of resection of asymptomatic congenital lung lesions are controversial. The morbidity of such surgery needs to be considered in the decision analysis. We analyzed the contemporary outcome of infants and neonates undergoing lung resection. METHODS With institutional review board approval, all patients 12 months or(More)
In the hippocampus, patterns of electrical stimulation that approximate bursting neuronal activity during theta rhythm have been shown to induce a long-term potentiation (LTP) of excitatory synapses. In this study, a single subthreshold stimulus applied to one set of Schaffer/commissural fibers affected the response to a second stimulation delivered 200 ms(More)
The use dependence of inhibitory postsynaptic potentials (IPSPs) and their underlying conductances was studied in area CA1 of the hippocampal brain slice preparation, using a two-pulse paradigm in which paired activation of two separate synaptic inputs resulted in changes in the second, or "primed" response. In intracellular current-clamp recordings, the(More)
The blood-brain barrier protects the brain from circulating compounds and drugs. The ATP-binding cassette (ABC) transporter P-glycoprotein (Pgp) is involved with the barrier, both preventing the influx of agent from the blood into the brain and facilitating the efflux of compounds from the brain into the blood, raising the possibility of a similar role for(More)
