Overview

The literature on aspiration pneumonia came into knowledge of medical society along with the discovery of pneumonia. During 1893, Veillon was first to write about the role of anaerobic bacteria in aspiration pneumonia. The major breakthrough came when x-ray was invented by Roentgen in 1896.

Historical Perspective

Following are important land mark events that shows how aspiration pneumonia became an important entity of critical care:[1][2][3][4][5][6]

Year Events
460 BC–380 BC Hippocrates described pneumonia.
1138–1204 AD Maimonides wrote about pneumonia as "The basic symptoms which occur in pneumonia and which are never lacking are as follows: acute fever, sticking pleuritic pain in the side, short rapid breaths, serrated pulse, and cough."
1875 Edwin Klebs identified bacteria in the airways of individuals who died from pneumonia.
1848 Carl Friedländer identified the two common bacteria such as Streptococcus pneumoniae and Klebsiella pneumoniae that cause pneumonia.
1893 Veillon was first to write about the role of anaerobic bacteria in aspiration pneumonia.
1896 Roentgen described x-rays.
1918 Sir William Osler, known as "the father of modern medicine," appreciated the morbidity and mortality of pneumonia, describing it as the "captain of the men of death."
1927 Smith was first to clearly show anaerobic bacterial growth in animal models suffered from aspiration pneumonia.
1929 Drinker and Shaw announced the invention of the iron lung during the
 polio epidemic.
1985 Specimen collected from patients with aspiration pneumonia were vastly cultured and it was called anaerobic bandwagon.

Lipoid pneumonia outbreak

  • During July and August 2019, five patients were identified at two hospitals in North Carolina with acute lung injury potentially associated with e-cigarette use.
  • Patients were adults aged 18–35 years and all experienced several days of worsening dyspnea, nausea, vomiting, abdominal discomfort and fever.
  • All patients demonstrated tachypnea with increased work of breathing on examination, hypoxemia (pulse oximetry <90% on room air), and bilateral lung infiltrates on chest x-ray.
  • All five patients shared a history of recent use of marijuana oils or concentrates in e-cigarettes.[7]
  • Thirty-three deaths confirmed due to vaping in 24 states of US, but lipoid pneumonia role in those moratlities was not proven.[8]
