Native Aortic and Tricuspid Valve Endocarditis Complicated by Embolic ST Elevation Myocardial Infarction.

Acute myocardial infarction due to a coronary embolic event can occur as a complication of infective endocarditis in up to 2.9% of cases and can frequently be the presenting symptom. A 35-year-old female presented with 4 hours of typical chest pain and was found to have ST elevations in inferior leads as well as an elevated serum Troponin I of 8.

ST-Elevation Myocardial Infarction Associated With Infective Endocarditis.

ST-elevation myocardial infarction (STEMI) as a complication of infective endocarditis (IE) is a rarely reported entity. No clear guidelines exist with regards to the management of this medical emergency. We sought to systematically review the clinical presentation and management of this condition.

Intact bronchogenic cyst presenting as a lung mass provoking a pleural effusion: a rare presentation.

This case report describes a 49 year old woman with an intra-parenchymal bronchogenic cyst masked on chest x-ray examination by a pleural effusion. The cyst was intact. It is likely that the cyst provoked the pleural effusion by repetitive mechanical irritation of the pleura.

Low inspiratory capacity to total lung capacity ratio is a risk factor for chronic obstructive pulmonary disease exacerbation.

Introduction: Air trapping because of chronic obstructive pulmonary disease (COPD) leads to a reduction in inspiratory capacity/total lung capacity (IC/TLC) ratio. We hypothesize that COPD patients with a low IC/TLC ratio suffer more frequent COPD exacerbations.

Methods: Retrospective cohort study of patients with COPD, aged 30 years or older with forced expiratory volume in 1 second <70% predicted and forced expiratory volume in 1 second/forced expiratory volume (FEV1/FVC) ratio <70% treated in our ambulatory care clinic for 3 years (2003-2006).

Clinical course and outcome of cocaine-induced pneumomediastinum.

Background And Objectives: Cocaine inhalation has been linked to the development of pneumomediastinum. The aim of this review was to identify the clinical course and outcome of spontaneous pneumomediastinum caused by cocaine use.

Material And Methods: We performed a literature search in English language using PubMed.
