Development of Ahmedabad's Air Information and Response (AIR) Plan to Protect Public Health.

Indian cities struggle with some of the highest ambient air pollution levels in the world. While national efforts are building momentum towards concerted action to reduce air pollution, individual cities are taking action on this challenge to protect communities from the many health problems caused by this harmful environmental exposure. In 2017, the city of Ahmedabad launched a regional air pollution monitoring and risk communication project, the Air Information and Response (AIR) Plan.

Pneumothorax, pneumomediastinum, subcutaneous emphysema and pneumorrhachis as complications of common flu.

Background: Spontaneous pneumomediastinum is an uncommon benign condition that is occasionally associated with subcutaneous emphysema and occasionally with pneumothorax, but is rarely associated with pneumorrhachis (air within the spinal epidural space).

Case Report: We describe the case of a 20-year-old man and discuss a classification system of pneumorrhachis and its pathoanatomy, clinical and radiological presentation and management based on a detailed review of the previous literature. The pathophysiology is multifocal and diagnosis is state-of-the-art, as free intra-spinal air collection and coexistence of it both should be differentiated.
