My Canadian Pharmacy Shares the Facts about Mortality From Acute Pulmonary Embolism According to Season

Varying observations have been reported on seasonal differences of mortality from acute pulmonary embolism (PE). Several investigators reported peak mortality rates in the first quarter of the year, sometimes with overlap in the last quarter, and sometimes with second peaks Read More

A SO-Year-Old Man With Skin Lesions and Multiple Pulmonary Nodules: Conclusion

Our case patient met each of the Coleman criteria. His rash, lymphadenopathy, and constitutional symptoms of fevers, chills, night sweats, and weight loss were all well-described clinical manifestations of secondary syphilis. Serologic testing, including positive rapid plasma reagin and fluorescent Read More

A SO-Year-Old Man With Skin Lesions and Multiple Pulmonary Nodules: Patients

Among the protean clinical manifestations of syphilis, pulmonary involvement is unusual. While nodular (or gummatous) and fibrotic lesions of the lung (usually with pleural involvement) are well established yet uncommon complications of tertiary syph-ilis, pulmonary involvement in secondary syphilis is Read More

A SO-Year-Old Man With Skin Lesions and Multiple Pulmonary Nodules: Diagnosis

Subsequent laboratory evaluation included the following: erythrocyte sedimentation rate, 49 mm/h; HIV by enzyme-linked immunosorbent assay, negative; viral hepatitis panel, negative; urine and blood cultures, no growth; skin biopsy fungal culture, no growth; antinuclear antibody, titer of 1:80 in a Read More

Feasibility of Routine Pulmonary Arterial Impedance Measurements in Pulmonary Hypertension: Clinical Implications

Thus, it may be that proximal pulmonary arterial changes leading to increased Zc and RF are predominantly the passive consequences of increased mean distending pressure, and that “fixed” proximal pulmonary arterial remodeling plays a minor role in determining RV hydraulic Read More

Feasibility of Routine Pulmonary Arterial Impedance Measurements in Pulmonary Hypertension: Effects of Pharmacologic Interventions

However, PVR is known to be insufficient for the evaluation of all the forces that oppose RV ejection, which result from a dynamic interplay among resistance, elastance, and wave reflection. This information is contained in Ppa and flow waves, and Read More

Feasibility of Routine Pulmonary Arterial Impedance Measurements in Pulmonary Hypertension: Pharmacologic Interventions

Inhaled NO therapy decreased Ppa and PVR, while Q, HR, and Psa remained unaffected. Z0, Z1; and Zc decreased, while Fmin, phase indexes, and RF were unchanged (Table 2). Epoprostenol therapy decreased PVR and Psa, increased Q, while HR remained Read More

Feasibility of Routine Pulmonary Arterial Impedance Measurements in Pulmonary Hypertension: Statistical Analysis

The dose of NO had been selected on the basis of findings from previous reports that 10 to 20 ppm allows the maximum possible pulmonary vasodilation in PAH patients. NO was supplied from a pure NO source tank (Oxhydrique; Machelen, Read More

Feasibility of Routine Pulmonary Arterial Impedance Measurements in Pulmonary Hypertension: Protocol

Ppa and flow signals were recorded after the pulmonary catheter was then carefully withdrawn to position its tip just above the pulmonary valve, as close as possible to the pulsed Doppler pulmonary artery flow-velocity sampling site. The signals were visually Read More
