The artery associated with the obliterated airway is also seen (far left of the image). H&E stain. Specialty: Pulmonology Symptoms
Pneumonic plague is a severe lung infection caused by the bacterium Yersinia pestis. [3] Symptoms include fever, headache, shortness of breath, chest pain, and coughing. [1] They typically start about three to seven days after exposure. [2] It is one of three forms of plague, the other two being septicemic plague and bubonic plague. [3]
Other methods of prevention include hand washing to prevent infection, prompt treatment of worsening respiratory symptoms, and not smoking. [10] [19] Treatment depends on the underlying cause. [20] Pneumonia believed to be due to bacteria is treated with antibiotics. [11] If the pneumonia is severe, the affected person is generally hospitalized ...
Respiratory syncytial virus, more commonly referred to as RSV, affects most people before they’re two years old. However, if you are older than 65 or a caregiver for someone older than 65, it ...
The neutrophils, bacteria, and fluid leaked from surrounding blood vessels fill the alveoli and result in impaired oxygen transportation. Bacteria can travel from the lung into the blood stream ( bacteremia ) and can result in serious illness such as sepsis and eventually septic shock , in which there is low blood pressure leading to damage in ...
In addition to the effects on the lungs, many viruses affect other organs and can lead to illness affecting many different bodily functions. Some viruses also make the body more susceptible to bacterial infection; for this reason, bacterial pneumonia often complicates viral pneumonia.
Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death. A common response cascade to a variety of irritant gases includes inflammation , edema and epithelial sloughing , which if left untreated can result in scar formation ...
The diagnosis of DPB requires analysis of the lungs and bronchiolar tissues, which can require a lung biopsy, or the more preferred high resolution computed tomography (HRCT) scan of the lungs. [7] The diagnostic criteria include severe inflammation in all layers of the respiratory bronchioles and lung tissue lesions that appear as nodules ...
