Comparison of two methods of surfactant administration and the effect on dosing-associated hypoxemia.

Objective: The purpose of our study was to test the hypothesis that surfactant dosing through a proximal sideport adapter on an endotracheal tube leads to more dosing-associated hypoxemia compared with a method of dosing that uses a double-lumen endotracheal tube.

Study Design: Using adequate sample size to compare significant changes in O2 saturation (power > 0.8, alpha < 0.

Objective: To determine the effect of bronchopulmonary dysplasia (BPD) on growth at school age.

Design: A prospective cohort study.

Methods: The sample included 406 children selected from a reconstructed cohort of infants of very low birth weight previously enrolled in a multisite, randomized, controlled clinical trial.

Renal lymphoma in ataxia-telangiectasia: CT contribution.

Ataxia-telangiectasia (AT) or the Louis-Bar syndrome is a familial, multisystem disorder. Patients with the disease are at high risk for malignancy, in particular lymphoreticular neoplasms, and immunodeficiency, rendering them susceptible to infection. We present a 17-year-old girl with AT and a history of lymphoma who developed a persistent fever.
