Wells score and Pulmonary Embolism Rule Out Criteria in preventing over investigation of pulmonary embolism in emergency departments.

Introduction: Unnecessary diagnostic tests are usually ordered to most of the patients with dyspnea or pleuritic chest pain, because of the worse outcomes of missed diagnosis of pulmonary embolism (PE). To identify rates and causes of over investigation for PE and to search whether it was possible to reduce this over investigation by using Wells score and Pulmonary Embolism Rule Out Criteria (PERC).

Materials And Methods: A retrospective observational cohort study performed in an emergency department of a tertiary care university hospital.

Dramatic response of a patient with pregnancy induced idiopathic pulmonary arterial hypertension to sildenafil treatment.

Idiopathic pulmonary arterial hypertension (IPAH) is characterized by a progressive increase in pulmonary vascular resistance, which may lead to right ventricular failure and death. Major cardiovascular and pulmonary alterations occur during pregnancy and therefore worsen or increase the complications of pulmonary arterial hypertension (PAH). A patient diagnosed with IPAH after a successful full-term pregnancy and cesarean section with epidural anesthesia is presented.
