One sign of pneumonia that people often miss is extreme fatigue. "I recently had a patient in his 70s with pneumonia whose main symptom was just severe fatigue and a high white cell count ...
Atypical pneumonia, also known as walking pneumonia, [1] is any type of pneumonia not caused by one of the pathogens most commonly associated with the disease. Its clinical presentation contrasts to that of "typical" pneumonia. A variety of microorganisms can cause it. When it develops independently from another disease, it is called primary ...
When signs of pneumonia are discovered during evaluation, chest X-rays and examination of the blood and sputum for infectious microorganisms may be done to support a diagnosis of CAP. The diagnostic tools employed will depend on the severity of illness, local practices and concern about complications of the infection.
If the symptoms worsen, the pneumonia does not improve with home treatment, or complications occur, hospitalization may be required. [69] Worldwide, approximately 7–13% of cases in children result in hospitalization, [ 23 ] whereas in the developed world between 22 and 42% of adults with community-acquired pneumonia are admitted. [ 69 ]
Rates of Mycoplasma pneumonia in all global community-acquired pneumonia (CAP) cases range from 10-15%. [13] [14] The rate of Mycoplasma pneumonia in adults with CAP is estimated to be 15%, and the rate of in children with CAP has been reported at 27.4%. [3] The rates of M. pneumoniae among hospitalized CAP cases are 35% in adults [14] and 24% ...
Legionnaires' disease is a form of atypical pneumonia caused by any species of Legionella bacteria, [3] quite often Legionella pneumophila. Signs and symptoms include cough, shortness of breath, high fever, muscle pains, and headaches. [2] Nausea, vomiting, and diarrhea may also occur. [1] This often begins 2–10 days after exposure. [2]
Atypical bacteria causing pneumonia are Coxiella burnetii, Chlamydophila pneumoniae (), Mycoplasma pneumoniae (), and Legionella pneumophila.. The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact that these organisms have atypical or absent cell wall ...
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 5 ] [ 6 ] [ 7 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
