Pneumonia-2

Pneumonia-2

in previous lecture we have learned
  • Pneumococcal pneumonia
  • staph pneumonia
  • their c/f,investigation,risk factors and treatment
in detail.
So now we will continue our discussion with

Bacillus anthracis pneumonia(biological weapons)

this pneumonia is also known as wool-sorters disease

Agent:

Gram positive rods (spore forming bacteria)

source:

spores of cattle wool, so it is also categorised as Zoonotic disease.Because this disease is caused by inhalation of spores

Risk factors:

  • cattle handler
  • form workers
  • abattoir

Clinical features:

  • high grade fever
  • productive cough with sputum production
  • dyspnea
  • chest pain(pleuritic chest pain)

Invstigation:

raised WBC’s

Investigation of choice:

sputum culture

Alternate investigation:

blood culture

Chest X-Ray:

broncho-pneumonia

Treatment:

inj benzyl penicillin

Alternate treatment:

ciprofloxacin

Pseudomonas pneumonia

Agent:

gram negative rod (enteric)

Mode:

  1. Hospital acquired pneumonia( HAP) – Leading cause
  2. Community acquired pneumonia(CAP) – 1-2% cases

Special risk factors for CAP:

  • pre-existing lung disease
  • COPD
  • ILD
  • Bronchiectasis

Clinical feature:

  • high grade fever
  • productive cough(greenish sputum)
  • dyspnea
  • chest pain(pleuritic chest pain)

General physical examination:

bronchial breath and coarse crepitation

investigation/investigation of choice/alternate investigation/chest X-ray:

all these are as same as Bacillus anthracis pneumonia

Treatment:

inj ceftriaxone OR Levofloxacin/moxifloxacin

if complication(septic shock/DIC)

then the treatment is Ticarcillin/Piperacillin
