Article Synopsis
- Snoring is linked to sleep-disordered breathing (SDB) and can impact cognitive and behavioral outcomes in adolescents, but its effects are less understood compared to younger children.

- Findings revealed a decline in habitual snorers from 6.8% to 3.2% over the study duration; however, snoring was not found to be significantly associated with cognitive impairments or behavioral issues among adolescents.

1,1'-azodi(formamide) (azodicarbonamide - ADCA) is widely used as a blowing agent, a chemical substance designed to induce foaming processes. In Poland, ADCA is manufactured by a company specializing in the production of polyethylene foam bags and laminates used in various industries including home appliances, electronics, construction, furniture, automotive, and sports and leisure. The mechanism of action of ADCA involves thermal decomposition, resulting in nitrogen, carbon monoxide, as well as ammonia and carbon dioxide as the main gaseous decomposition products.

Despite inhaled corticosteroid therapy, her symptoms persisted, and spirometry indicated obstructive lung function without bronchodilator response. Chest CT revealed diffuse thickening of the esophageal wall, tracheal compression, with involvement of the gastric cardia, suggestive of diffuse leiomyomatosis.
