Preschool wheezing can be divided into "viral-induced wheeze" and "multi-trigger wheeze". Viral-induced wheezing accounts for about two-thirds of all preschool wheezes. The wheezing symptom is episodic and the child is completely normal in between wheezing episodes. It has a good prognosis and only supportive treatment is required. Meanwhile ...
Acute bronchiolitis is usually the result of viral infection by respiratory syncytial virus (RSV) (59.2% of cases) or human rhinovirus (19.3% of cases). [7] Diagnosis is generally based on symptoms. [1] Tests such as a chest X-ray or viral testing are not routinely needed, but may be used to rule out other diseases. [2]
Adenovirus infection is a contagious viral disease, caused by adenoviruses, commonly resulting in a respiratory tract infection. [1] [9] Typical symptoms range from those of a common cold, such as nasal congestion, rhinitis, and cough, to difficulty breathing as in pneumonia. [9]
In adults, foreign body aspiration is often associated with an altered state of consciousness. The foreign body is often unchewed food, or part of a tooth or crown . [ 33 ] Bronchiectasis that results from foreign body aspiration generally occurs in the right lung in the lower lobe or posterior segments of the upper lobe.
Mild peribronchial cuffing as seen in viral bronchitis. A physical examination will often reveal decreased intensity of breath sounds, wheezing, rhonchi, and prolonged expiration. During examination, physicians rely on history and the presence of persistent or acute onset of cough, followed by a URTI with no traces of pneumonia.
Most often it is caused by viral infection and hence antibiotic therapy is not indicated in immunocompetent individuals. [10] [7] Viral bronchitis can sometimes be treated using antiviral medications depending on the virus causing the infection, and medications such as anti-inflammatory drugs and expectorants can help mitigate the symptoms.
While the acronyms are similar, reactive airway disease (RAD) and reactive airways dysfunction syndrome (RADS) are not the same. [1]Reactive airways dysfunction syndrome was first identified by Stuart M. Brooks and colleagues in 1985 as an asthma-like syndrome developing after a single exposure to high levels of an irritating vapor, fume, or smoke.
A postinfectious cough is a lingering cough that follows a respiratory tract infection, such as a common cold or flu and lasting up to eight weeks. Postinfectious cough is a clinically recognized condition represented within the medical literature.
