What is a common acute viral infection in children characterized by the obstruction of the larynx and stridor?

Croup is a common respiratory illness of the trachea, larynx, and bronchi that can lead to inspiratory stridor and barking cough. It is a self-limited disease that is seen in children under the age of 5.

Which of the following is a viral inflammation of the larynx and the trachea that causes edema and spasm of the vocal cords?

Acute laryngitis generally results from a viral infection that causes edema of the vocal cords, either by directly infecting the tissues or by stimulating excessive secretions that lead to inflammation. Most cases of acute laryngitis are caused by viruses (◘ Fig.

What is a highly contagious upper respiratory infection characterized by sudden coughing and a whooping inhalation?

Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis. These bacteria attach to the cilia (tiny, hair-like extensions) that line part of the upper respiratory system.

What infections can Caase obstruction of the airway?

Fortunately, these are mostly due to self-limiting viral laryngotracheobronchitis (LTB), but there is also a group of bacterial infections (e.g., epiglottitis, bacterial tracheitis, diphtheria, retropharyngeal abscess, and peritonsillar abscess) that can occasionally cause significant obstruction.

What happens when airway is blocked?

A blockage in your airway could prevent your body from getting enough oxygen. A lack of oxygen can cause brain damage, and even a heart attack, in a matter of minutes. Any obstruction of the upper airway has the potential to be life-threatening.

What is an acute respiratory syndrome in children and infants characterized by the obstruction of the larynx hoarseness and a barking cough?

This disease has 3 stages: catarrhal, paroxysmal, and convalescent. The symptoms of the catarrhal stage are mild and may go unnoticed. The paroxysmal stage of Pertussis is characterized by episodes of coughing with a distinctive “whooping” sound when breathing in (inspiration).

What does catarrhal stage mean?

The initial (catarrhal) phase is indistinguishable from common upper respiratory infections. It includes nasal congestion, rhinorrhea, and sneezing, variably accompanied by low-grade fever, tearing, and conjunctival suffusion.
