Electrocardiograms of adult outpatients followed-up in basic health care units in the community of the South region of São Paulo City.

Objective: The electrocardiogram (ECG) is an important, available, and inexpensive diagnostic tool to assess cardiac symptoms. Few studies address the prevalence of ECG abnormalities or changes of a normal tracing in ECG in outpatients. Our objective was to evaluate ECGs of adult outpatients to determine whether changes from a normal tracing could disclose the patients' cardiovascular health status.

Laryngeal and tracheobronchial involvement in Wegener's granulomatosis.

Introduction: Wegener's granulomatosis (WG) is a form of systemic vasculitis that involves primarily the upper and lower airways and the kidneys. The most frequent airway manifestations include subglottic stenosis and inflammation, and tracheal and bronchial stenoses. The endoscopic visualization of the airways is the best tool for assessing, diagnosing and managing those changes.
