A Case Series of E-cigarette or Vaping-Associated Lung Injury With a Review of Pathological and Radiological Findings.

There has been a recent outbreak of e-cigarette or vaping-associated lung injury (EVALI) but the exact pathophysiology remains unknown. Tetrahydrocannabinol (THC) and vitamin E derivates are the major components in vaping-generated aerosols that are associated with EVALI. So far, there is no standard treatment for EVALI.

Prospective Randomized Controlled Pilot Study of High-Intensity Lightbox Phototherapy to Prevent ICU-Acquired Delirium Incidence.

Background This study aimed to evaluate the role of disturbed circadian rhythm in potentiating intensive care unit (ICU)-acquired delirium.Previous studies have demonstrated bright light therapy (BLT) as an effective modality to improve sleeping patterns and cognitive function in non-critically ill patients. However, its benefit in the ICU has not been clearly established.

Three decades of transtracheal oxygen therapy: A review of the associated complications with an illustrative case presentation.

Transtracheal oxygen therapy is a well-established modality for improving oxygenation in patients with chronic obstructive pulmonary disease, sleep apnea, pulmonary fibrosis, and other conditions causing hypoxic respiratory failure. In spite of its proven track record, the device remains underutilized. This article reviews benefits and complications related to the use of this modality with an illustrative case presentation.

Transtracheal oxygen and positive airway pressure: A salvage technique in overlap syndrome.

The coexistence of sleep apnea-hypopnea syndrome (SAHS) with chronic obstructive pulmonary disease (COPD) occurs commonly. This so called overlap syndrome leads to more profound hypoxemia, hypercapnic respiratory failure, and pulmonary hypertension than each of these conditions independently. Not infrequently, these patients show profound hypoxemia, despite optimal continuous positive airway pressure (CPAP) therapy for their SAHS.
