via and lower extremity veins using ttmTc-albu. mm microspheres was performed in 53 patients with pulmonary emboli or venous disease. In 25 patients who underwent both contrast and RNV studies, there were no false-positive studies and one false-negative. In this series the accu racy of RNV exceeded that of Doppler alone. When the results of these two methods were combined, false-negative studie...

A patient underwent exercise testing during evaluation for unexplained dyspnea. Evidence of ventilation-perfusion mismatch was noted and subsequent testing revealed multiple pulmonary emboli. Ventilation perfusion parameters by serial exercise testing progressively improved during the course of the patient's illness but did not totally normalize. A discussion of the utility of exercise testing ...

Endocarditis is a rare presentation of group B streptococcal infection. Its association with pulmonary septic embolism was only barely studied and limited data is available up to date. Multiple septic emboli is a common complication of bacterial endocarditis, but only a few cases have been documented in relation to group B streptococcus.

We submit here an unusual case in which a user of crack cocaine presented with progressive dyspnea of subacute duration and was subsequently found to have concurrent pericardial and pleural effusions and pulmonary emboli. To our knowledge, there is only one prior case report that describes a potential causal relationship between crack cocaine and the development of a pleural effusion, via an eo...
