Abstract:
Since March 2019, E-cigarette or Vaping product associated lung injury (EVALI) has become an ongoing epidemic with more 2600 cases reported in the span of a few months in the United States. EVALI is defined as acute lung injury that develops secondary to the use of e-cigarettes or vaping products within the previous 90 days after exlusion of other possible inciting factors. Vitamin E acetate is believed to play a significant role in its pathogenesis. Treatment involves use of corticosteroids and further avoidance of these products. We describe a case series of 8 patients with EVALI, their clinical course and outcomes. All patients showed an excellent response to corticosteroids. In our experience, prognosis of EVALI is excellent, with complete resolution of symptoms in patients who followed up at 8 weeks.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
