Neurally adjusted ventilatory assist (NAVA) is a mode of mechanical ventilation in which positive pressure is applied to the airway opening in proportion to the electrical activation of the diaphragm (EAdi).1 With NAVA, ventilator support is initiated when the neural drive to the diaphragm begins to increase. As the EAdi progressively increases, the assist increases […]
After the report in 1946 by Samson and Burford, open procedures for empyema thoracis were often delayed until pleurodesis was assured if surgery could not be performed within the first three weeks. Eloesser subsequently developed an ingenious flap technique to drain the empyema cavity after it was allowed to mature to the point of ensuring […]

Whereas none of our subjects claimed to have dyspnea at rest, during control exercise at 60% of WLmax, dyspnea scores ranged between 3.5 and 9. With PLB, breathlessness increased in four of the eight patients, was relatively unaltered in two patients, and decreased in two patients (Fig 1). Effect of PLB on Breathing Pattern Individual […]
Angiotensin-converting enzyme (ACE) is a dipeptidyl carboxypeptidase which hydrolyzes angiotensin 1 to form angiotensin 2 and also inactivates bradykinin. It occurs on vascular endothelium in all organs and in other tissues such as brain, kidney, gut and testis, as well as in Gauchers cells, pulmonary macrophages, and peripheral blood monocytes. In human blood monocytes, ACE […]
The percentage of patients with active sarcoidosis reported to have elevations of serum ACE has varied considerably in different laboratories, ranging from 35 percent to almost 100 percent. Our laboratory has consistently reported that 75 percent of such patients have elevated levels of serum ACE with an additional 15 percent falling within the “borderline elevated” […]
Intracardiac rupture of a dissecting aortic aneurysm is a rare event. Although previous cases of rupture into the right atrium (RA) have been reported, we are unaware of any other report of communication into the superior vena cava (SVC). We recently had the opportunity to study and localize the site of fistula by continuous fiberoptic […]
