Occluder Device Removal and Total Septation of "Swiss-Cheese" Ventricular Septal Defects.

"Swiss-cheese" ventricular septal defects present complex treatment challenges. Despite difficult defect visualization and closure, complete septation is the treatment of choice. We present the case of a 2-year-old with residual apical "Swiss-cheese" ventricular septal defects after failed percutaneous device closure with 2 occluder devices.

Pulmonary Atresia Intact Ventricular Septum With Anomalous Left Coronary Artery From Pulmonary Artery.

A patient with known pulmonary atresia and intact ventricular septum and ductal stent presented with low cardiac output and arrythmia. Intraoperatively, the patient was found to have an anomalous left coronary artery arising from the pulmonary artery. After reimplantation of the left coronary artery to the aortic root and placement of a central shunt, the patient progressed well and was discharged home.

Complete Resection of Aorticopulmonary Paraganglioma With Reconstruction in a Pediatric Patient.

Aorticopulmonary paragangliomas are exceedingly rare tumors in pediatric populations. Complete surgical resection is the only curative treatment. However, resection is challenging due to the vascularity of paragangliomas and their close relationship with the great vessels.

Control optimization of air traffic emissions in a two-variable dynamic model.

Since 1999, every report released by the International Panel on Climate Change has advocated a decrease in the greenhouse gas emissions associated with aviation in order to preserve the current climate. This study used a two variable differential equations model with a non-linear control term to address several aspects of the emissions stabilization issue. By optimizing the control term parameter, several management alternatives can be obtained based on the properties of the phase plane of the model solutions, as identified by a stability analysis.

Pharmacogenetics of Neoadjuvant MAP Chemotherapy in Localized Osteosarcoma: A Study Based on Data from the GEIS-33 Protocol.

Osteosarcoma is a rare disease, but it is the most frequent malignant bone tumor. Primary treatment consists of preoperative MAP (methotrexate (MTX), doxorubicin and cisplatin) chemotherapy followed by surgery and adjuvant chemotherapy. Pathological response to preoperative chemotherapy is one of the most important prognostic factors, but molecular biomarkers are lacking.
