Clinical implications of heart-lung interactions

As opposed to spontaneous respiration wherein small cyclic changes in transpulmonary, negative pressure coincide with lung volume changes, positive pressure (mechanical) ventilation results in a simultaneous rise in transpulmonary pressure and lung volumes. The changes may affect biventricular cardiac loading and function in dissimilar ways, depending on baseline cardiopulmonary function. This review is intended to update current knowledge on the pathophysiology of these heart-lung interactions in helping to explain the common circulatory alterations occurring during airway pressure changes and to better understand mechanisms of disease and modes of action of treatments, during spontaneous and mechanical ventilation.

A health education program for underserved community youth led by health professions students

OBJECTIVES

To develop and implement a health fair and educational sessions for elementary school children led by health professions students.

DESIGN

The structure and process were developed with elementary school administration to determine the health topics to be covered. Students and faculty members created a "hands-on," youth-oriented health fair and interactive health educational sessions. Quantitative and qualitative data were collected on learning outcomes from the underserved child population and health professions students.

ASSESSMENT

The health fair and educational sessions increased awareness of underserved youth in the areas of critical health behaviors, purposeful education on health issues facing their community, and exposure to careers in various health professions. The activities provided meaningful learning experiences for the health professions students.

CONCLUSION

The health education program model is an excellent way to teach health education, communication and critical thinking skills, and service learning to health professions students.

Mini-review on cardiac complications after mediastinal irradiation for Hodgkin lymphoma

We present a 62-year-old man who over the years developed almost all the possible cardiac complications of radiation therapy after treatment of a Hodgkin's lymphoma. A review of the literature and a summary of treatment options for cardiac complications after irradiation of the mediastinum for Hodgkin's lymphoma are presented.
