Objectives/hypothesis: We will describe the treatment of patients with subglottic and tracheal stenosis using instruments and techniques utilized by otolaryngologists and interventional pulmonologists (IP), with a focus on IP-favored approaches that may be less familiar to otolaryngologists. We will present two cases that were treated cooperatively by otolaryngology and IP and will highlight the advantages of certain techniques.

Study Design: Case series METHODS: This is a case-based presentation highlighting procedures done cooperatively by otolaryngology and IP.

Leveraging the capabilities of the Historical Spatial Data Infrastructure (HSDI) and composite indices we explore the importance of children's built and social environments on health. We apply contemporary GIS methods to a set of 2000 historical school records contextualized within an existing HSDI to establish seven variables measuring the relative quality of each child's built and social environments. We then combined these variables to create a composite index that assesses acute (short-term) health risks generated by their environments.

The purpose of this column is to present an action-oriented health equity framework derived from Beauchamp and Childress' four ethical principles (ie, autonomy, beneficence, nonmaleficence, and justice) and centred around the specific needs of marginalized and excluded communities of the Champlain region of Ontario. It describes the conceptual underpinnings of the framework, defines its components, and demonstrates how it can be applied. The principle-based health equity framework is a useful tool to reduce health disparities within healthcare organizations; it is designed to promote the incorporation of health equity objectives, strategies, principles, and measurements into healthcare organizations' strategic planning processes and operations.
