Pulmonary Petechiae: Ventilatory-Circulatory Interactions

Fever, petechiae, and pulmonary infiltrates in an immunocompromised Peruvian man.

The diagnostic considerations raised by immunocompromised patients with opportunistic infection continue to expand. When such patients harbor latent or persistent infection acquired in a tropical environment, the diagnostic challenge is even greater. The Infectious Disease Service at Yale-New Haven Hospital was asked to see a middle-aged man from Peru with known T-cell lymphoma who had recently...

The Circulatory and Ventilatory Effects of Normovolemic Polycythemia †

The effects of primary and secondary polycythemia on circulatory and ventilatory events have been the center of much investigation. There has, however, been sharp disagreement about the clinical merit of phlebotomy in cases of secondary polycythemia. Howarth, et al.' and Lewis, et al.,' among others, have concluded, although for somewhat different reasons, that therapeutic phlebotomy is detrime...

Petechiae in a Newborn.

A 29-year-old woman delivered at 39 weeks’ gestation by elective repeat cesarean delivery. After this delivery, she was gravida 3, para 2, aborta 1. There was a nuchal cord during delivery, but the newborn had Apgar scores of 8 and 9. The pregnancy was complicated by the mother’s obesity and rubella nonimmune status. Her blood type was O Rh-positive. Findings on the initial newborn examination ...

Circulatory power and ventilatory power over time under goal-oriented sequential combination therapy for pulmonary arterial hypertension

Many therapeutic options are available for patients with pulmonary arterial hypertension (PAH). However, little is known about the effects of sequential combination therapy on exercise capacity. Here we monitored exercise capacity by cardiopulmonary exercise testing (CPX) and observed the benefit of using a peak VO2 cutoff of 15 mL/kg/min to guide combination therapy. Thirty patients newly diag...
