The Berlin Criteria specifies: [4] Timing: onset of respiratory symptoms within one week of an injury/insult. Chest Imaging: either chest x-ray or CT scan, must show bilateral opacities that cannot be fully explained by other conditions such as effusion, lung/lobar collapse, or lung nodules.
Early investigators distinguished between typical lobar pneumonia and atypical (e.g. Chlamydophila) or viral pneumonia using the location, distribution, and appearance of the opacities they saw on chest x-rays. Certain x-ray findings can be used to help predict the course of illness, although it is not possible to clearly determine the ...
Viral pneumonia is a pneumonia caused by a virus. Pneumonia is an infection that causes inflammation in one or both lungs. Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [ 1 ]
Acute severe asthma, also known as status asthmaticus, is an acute exacerbation of asthma that does not respond to standard treatments of bronchodilators (inhalers) and corticosteroids. [2] Asthma is caused by multiple genes , some having protective effect, with each gene having its own tendency to be influenced by the environment although a ...
Unlike pneumonia, asthma and COPD typically present with wheezing, pulmonary edema presents with an abnormal electrocardiogram, cancer and bronchiectasis present with a cough of longer duration, and pulmonary emboli present with acute onset sharp chest pain and shortness of breath. [9]
Ground-glass opacity is most often used to describe findings in high-resolution CT imaging of the thorax, although it is also used when describing chest radiographs. In CT, the term refers to one or multiple areas of increased attenuation (density) without concealment of the pulmonary vasculature. This appears more grey, as opposed to the ...
White lung pneumonia is not a specific type of pneumonia, Dr. Ganjian says. “It is simply a term that has been used to describe pneumonia that appears white on chest X-rays,” he explains.
There is a strong association of C. pneumoniae with long-standing asthma among the non-atopic asthma in comparison to atopic asthma. [2] In fact, the severity of asthma can be determined by the elevated titres to C. pneumoniae, but not to other potential pathogens such as Mycoplasma pneumoniae, adenovirus, influenza A and B or parainfluenza ...
