NIV improves hypoxemia and the signs and symptoms of acute respiratory failure. NIV seems to afford these patients protection from endotracheal intubation.

Infants with simple respiratory distress syndrome could be segregated from those infants who developed bronchopulmonary dysplasia by the magnitude of the epithelial lining fluid oxyradical inflammation markers. While infants developing bronchopulmonary dysplasia typically exhibited increased concentrations of these markers during the first week of life, those infants with simple respiratory distress syndrome displayed low, uniform, or decreasing values of these markers over this interval. Infants developing bronchopulmonary dysplasia demonstrate an early pulmonary inflammatory response, and one key aspect of this response involves various oxyradical-generating systems.

Extra-adrenal pheochromocytomas are of rare occurrence. Since first reported laparoscopic adrenalectomy has become the gold standard in the treatment of adrenal tumors, the feasibility of laparoscopic adrenalectomy in the setting of pheochromocytoma has also been established given a careful preoperative planning. Literature on the laparoscopic treatment of extra-adrenal pheochromocytomas is lacking. We report a hypertensive 54-year-old male patient (body mass index, 26.2) with elevated urinary catecholamines and a 6-cm solid mass under the right renal hilum diagnosed after a magnetic resonance. The patient underwent complete transperitoneal laparoscopic excision of the tumor. Recovery was uneventful and final histopathologic examination showed an extra-adrenal pheochromocytoma. We believe that transperitoneal laparoscopic excision of extra-adrenal pheochromocytoma is a feasible and reproducible technique that allows for complete removal of tumoral tissue with low morbidity, shorter hospital stay, and minimal convalescence.
