Successful thoracoscopic excision of complex supracardiac middle mediastinal bronchogenic cyst in an infant.

Introduction: We report the first case of complex supracardiac middle mediastinal foregut duplication lesion compressing and adherent to the heart, managed successfully thoracoscopically in an infant, in an innovative way.

Materials And Surgical Technique: A 1-year-old girl was diagnosed as having supracardiac middle mediastinal foregut duplication lesion. It was completely overlying and adherent to her heart giving transmitted pulsations to the lesion, causing indentation over the left atrium and surrounded by all vital structures such as aorta, pulmonary artery, bronchi and phrenic nerve.

Evaluating efficiency-equality tradeoffs for mobile source control strategies in an urban area.

In environmental risk management, there are often interests in maximizing public health benefits (efficiency) and addressing inequality in the distribution of health outcomes. However, both dimensions are not generally considered within a single analytical framework. In this study, we estimate both total population health benefits and changes in quantitative indicators of health inequality for a number of alternative spatial distributions of diesel particulate filter retrofits across half of an urban bus fleet in Boston, Massachusetts.
