It is the acute inflammation of the bronchi, accompanied by inflamed patches in the nearby lobules of the lungs. [1] It is often contrasted with lobar pneumonia; but, in clinical practice, the types are difficult to apply, as the patterns usually overlap. [2] Bronchopneumonia (lobular) often leads to lobar pneumonia as the infection progresses.
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument (bronchoscope) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy.
In “Type 2” the bronchus is contained in the tumor. These types are more common in malignant nodules. A compressed and narrowed bronchus is defined as “Type 3”, and can occur in both benign and malignant nodules. Narrowing of the proximal bronchial tree is described as “type 4” and is associated with malignancy.
Common causes include congestive heart failure. [22] Stridor a high-pitched musical breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree. [23] It is not to be confused with stertor. Causes are typically obstructive, including foreign bodies, croup, epiglottitis, tumours, infection and anaphylaxis.
The lower respiratory tract consists of the trachea (windpipe), bronchial tubes, bronchioles, and the lungs. [6] Lower respiratory tract infections (LRIs) are generally more severe than upper respiratory infections. LRIs are the leading cause of death among all infectious diseases. [7] The two most common LRIs are bronchitis and pneumonia. [8]
Lobar pneumonia is often due to Streptococcus pneumoniae (though Klebsiella pneumoniae is also possible.) [16] Multilobar pneumonia involves more than one lobe, and it often causes a more severe illness. Bronchial pneumonia affects the lungs in patches around the tubes (bronchi or bronchioles).
It’s important to point out that Mycoplasma pneumoniae doesn’t always cause pneumonia. In fact, the CDC points out that it can also cause a simple cold. In fact, the CDC points out that it can ...
The bacterium Streptococcus pneumoniae, a common cause of pneumonia, imaged by an electron microscope. Pneumonia is due to infections caused primarily by bacteria or viruses and less commonly by fungi and parasites. Although more than 100 strains of infectious agents have been identified, only a few are responsible for the majority of cases.
