MARDER--multi-axes rotation device for experimental research. A new concept for investigations of the vestibular, oculomotor, and visual systems of humans in three-dimensional space.

A hydraulically driven, digitally servo-controlled multi-axes rotary chair is described. This device generates motion profiles with the subjects head in the center of rotation mainly in order to adequately stimulate the semicircular canals which are sensitive sensors for angular accelerations. This newly developed apparatus allows for motion stimuli which are below the vestibular threshold up to accelerations of 12 rad/s2 (688 degrees/s2) and is thus suitable for a variety of experiments in the field of vestibular, oculomotor, and intersensory research in 3-dimensional space.

Chylothorax complicating right upper lobectomy.

Chylothorax after pleuropulmonary surgery is unusual. We have described the case of a patient in whom this complication followed a right upper lobectomy. Early recognition is important to avoid potential morbidity and mortality.

Surgical therapy for left ventricular aneurysms. A ten-year experience.

We reviewed retrospectively the surgical results of left ventricular aneurysm reduction in 197 consecutive patients operated on in 1977-1987. There were 19 hospital deaths (9.6%) and 38 late deaths. The cumulative 5- and 10-year survival probabilities were 79% and 67%. Of the 140 late survivors, 130 underwent follow-up study in 1988 (mean, 5 years postsurgery). We analyzed preoperative, perioperative, and postoperative variables to evaluate the efficacy of surgical therapy. The risk of early mortality was increased by worsening preoperative New York Heart Association class, operation within 30 days of myocardial infarction, combinations of ventricular arrhythmia and congestive heart failure, renal failure, and preoperative cardiogenic shock. There was a trend toward increased early mortality with multivessel coronary artery disease. Late mortality and length of survival were not predicted by any variable examined.
