Introduction: Although it has been suggested that orthodontic treatment might lead to changes in the dental pulp, no clinical study has attempted to investigate the incidence of pulp necrosis after orthodontic therapy. The purpose of this clinical trial was to determine whether pulp testing response is altered after rapid palatal expansion (RPE).
Methods: Twenty-five adolescent patients (9 boys, 16 girls; ages, 10-16 years) participated in the study.
Background: Nesiritide is recombinant human B-type natriuretic peptide with vasodilatory effects used in patients with decompensated congestive heart failure. We sought to evaluate the effects of nesiritide on left ventricular diastolic function in heart failure patients.
Methods And Results: Twenty-five heart failure patients underwent left heart catheterization (using a pressure-volume conductance catheter) and echocardiography at baseline and 30 minutes after an intravenous bolus and infusion of nesiritide.

Introduction: Diagnostic measurements have traditionally been made on plaster dental casts. Now, 3-dimensional digital dental models can be used. The purpose of this study was to compare space analysis measurements made on digital models with those from plaster dental casts.

However, the impact of passive smoke exposure on angina status and therapeutic response is less well-established. We examined the impact of second-hand smoke (SHS) exposure on symptomatic improvement in patients with chronic ischemic coronary disease undergoing enhanced external counterpulsation (EECP).

We assessed the correlation between systolic dysfunction and EMAT calculated using computerized acoustic cardiography.
Methods: A total of 25 patients with heart failure contemporaneously underwent echocardiography, left-sided heart catheterization, and acoustic cardiography.
