BACKGROUND/PURPOSE The management of asymptomatic congenital lung lesions is controversial. It is unclear whether elective resection provides a significant benefit. We sought to determine whether early vs delayed resection of asymptomatic congenital lung malformations resulted in complications. METHODS Institutional billing records were queried for(More)
BACKGROUND The phosphatidylinositol 3-kinase (PI3K), a critical intracellular pathway, is negatively regulated by phosphatase and tensin homologue (PTEN). Integrin-linked kinase (ILK) induces phosphorylation of Akt leading to an increase in cell survival. However, a potential interaction between ILK and PTEN activity in neuroblastoma cells is unknown. We(More)
Activation of PI3K/AKT pathway correlates with poor prognosis in patients with neuroblastoma. Our previous studies have demonstrated that PI3K/AKT signaling is critical for the oncogenic transformations induced by gastrin-releasing peptide (GRP) and its receptor, GRP-R, in neuroblastoma. Moreover, PI3K/AKT-dependent oncogenic transformations require N-myc,(More)
OBJECTIVE Alternatively activated macrophages (M2) are associated with the progression of spasmolytic polypeptide-expressing metaplasia (SPEM) in the stomach. However, the precise mechanism(s) and critical mediators that induce SPEM are unknown. DESIGN To determine candidate genes important in these processes, macrophages from the stomach corpus of mice(More)
BACKGROUND Despite the success of childhood immunizations in prevention of infectious diseases, questions remain about the safety of vaccines in medically fragile children with inborn errors of metabolism such as urea cycle disorders (UCDs). Patients with UCDs are subject to hyperammonemic episodes (HAEs) after infection, fever, or other stressors. (More)
BACKGROUND Concomitant thyroid pathology in patients with primary hyperparathyroidism is common. This study compares complications of patients who underwent parathyroidectomy to those who underwent parathyroidectomy with a concomitant thyroidectomy. METHODS A retrospective review of prospectively collected data on 709 patients who underwent(More)
BACKGROUND Intracellular signaling responsible for gastrin-releasing peptide (GRP) receptor-mediated neovascularization is not clearly understood. We sought to determine the cellular mechanisms involved in the GRP receptor regulation of vascular endothelial growth factor (VEGF) release in neuroblastoma cells. MATERIALS AND METHODS BE(2)-C cells were(More)
BACKGROUND We sought to determine if bilateral neck exploration (BNE) for hyperparathyroidism could be performed safely in an ambulatory setting (same-day discharge) when compared with focused parathyroidectomy. METHODS A retrospective review of 503 patients who underwent parathyroidectomy from 2010 to 2015 was performed. Focused parathyroidectomy was(More)
