Differential diagnosis

Differential diagnosis of paroxysmal cough:

1, spastic cough: spastic cough is characterized by severe cough, a cough with a sound, a cough can be dozens of sounds to dozens of sounds for a long time, coughing when the face and neck are red, breathing is affected, Deep coughing often requires deep inhalation. Severe coughing often causes glottic sputum. It sounds like a chicken. Sudden and severe cough often causes retching. After a short cough, it starts to cough and can cause coughing. Laced ulcers, subconjunctival hemorrhage, severe abdominal pressure caused by cough, umbilical hernia, inguinal hernia and rectal prolapse, spastic cough are common in whooping cough, parapertussis and some adenovirus infections.

2, persistent cough: cough is one of the most common symptoms in the respiratory system, is a protective measure of the human body, is beneficial to the body, when the respiratory mucosa is stimulated by foreign bodies, inflammation, secretions or allergic factors That is, it causes reflexive coughing, which helps to exclude foreign bodies or secretions that invade the respiratory tract from the outside, and eliminates respiratory tract stimulating factors. Persistent cough is a precursor to lung disease. This cough will take two to three months to heal once it starts, and any cough medicine seems to be powerless.

3, allergic cough: allergic cough (AC) as an independent disease has not been recognized. The definition of it is still only in a descriptive stage, lacking a large number of systematic research observations. Mainly refers to a clinical Some patients with chronic cough have some atopic factors, antihistamines and glucocorticoids are effective, but can not be diagnosed as asthma, allergic rhinitis or eosinophilic bronchitis (EB) is not suitable for other disease. This type of cough is defined as AC. Its relationship and similarities with allergic pharyngitis, EB, cough after a cold, etc. need to be further explored to determine whether it is an independent disease entity.
