Coughing rust-colored phlegm

Introduction Cough rust is common in lobar pneumonia, and lobar pneumonia is mainly caused by Streptococcus pneumoniae. The lesion involves a lung tissue above the lung segment, and acute inflammation is mainly caused by diffuse cellulose exudation in the alveoli. The lesion begins in the local alveoli and spreads rapidly to a segment of the lung or to the entire lobules. Clinically, the onset is rapid, often starting with high fever and aversion to cold, followed by chest pain, cough, cough and rust, difficulty breathing, and signs of lung consolidation and increased white blood cell count in peripheral blood. The course of the disease lasted about a week, the body temperature plummeted and the symptoms disappeared. The disease mostly occurs in young men.

Cause

A variety of bacteria can be caused, but the vast majority are Streptococcus pneumoniae, of which type III is the most pathogenic. Streptococcus pneumoniae is a Gram-positive cocci, with a capsule, and its pathogenicity is due to the invasion of the capsule of the polymer polysaccharide to the tissue. A few are Klebsiella, Staphylococcus aureus, Streptococcus hemolyticus, Haemophilus influenzae, and the like.

1. Onset of illness, chills, high fever, chest pain, cough, cough and rust. A wide range of lesions can be associated with shortness of breath and purpura.

2. Some cases have nausea, vomiting, abdominal distension, and diarrhea.

3. Severe cases may have neuropsychiatric symptoms, such as irritability, paralysis and so on. It can also occur in peripheral loop failure and complicated with septic shock, called shock (or toxic) pneumonia.

4. Acute illness, shortness of breath, nose flapping.

5. Early lung signs are not obvious or only breath sounds are reduced and pleural friction sounds. The consolidation period may have typical signs, such as weakened respiratory movement on the affected side, increased vocal fibrillation, percussive dullness, auscultation of reduced breath sounds, wet rales or pathological bronchial breath sounds.

Differential diagnosis

The disease is easily confused with the following diseases, pay special attention to the diagnosis:

(1) Cases of tuberculous pneumonia have a history of tuberculosis. Slow white blood cell counts are normal. Tuberculosis can be found in X-ray examination. There may be cavities in the lungs.

(2) The secondary infection of lung cancer is older and the onset of symptoms is slow. The symptoms of poisoning are not obvious. There may be X-ray examination and fiberoptic bronchoscopy or assisted diagnosis in the middle of the sputum.

(3) acute lung abscess often a large number of purulent sputum X-ray examination of the formation of cavities in the fluid plane can be identified.
