- Definition and strict conditions required to diagnose pneumonia..........def .. acute inflammation of the lung parenchyma, specifically the part involved in gas exchange
to diagnose pneumonia, a patient must have both clinical and radiological evidence of consolidation
- The most common and critical organism causing pneumonia..........Streptococcus pneumoniae (also known as Pneumococcus)
- The clinical significance of asking the patient to cough during auscultation..........to differentiate between persistent clinical findings and simple secretions. If a sound (like a wheeze or crepitation) disappears or changes after the patient coughs, it was likely due to secretions
- CURB-65 criteria, parameters, and application..........
- C (Confusion): New onset of altered mental status.
- U (Urea): Level > 7 mmol/L (or > 20 mg/dL).
- R (Respiratory Rate): ≥ 30 breaths per minute.
- B (Blood Pressure): Low systolic (< 90 mmHg) or diastolic (≤ 60 mmHg).
- 65 (Age): Patient is 65 years of age or older.
Application of the score:
- 0–1 point: Low risk; suitable for outpatient treatment.
- 2 points: Moderate severity; consider short inpatient hospitalization or closely supervised outpatient care.
- 3–5 points: High severity; hospitalization is required, and ICU admission should be considered
- Biomarkers and their specific reduction thresholds for stopping antibiotic therapy..........The two primary biomarkers used to guide the duration of antibiotic therapy are CRP and Procalcitonin.
- CRP (C-reactive protein): Antibiotics can be stopped if the level drops by more than 50% (typically assessed between 3 to 5 days of treatment).
- Procalcitonin: Antibiotics can be stopped if the level drops by more than 90% (for example, falling from 4 to 0.5)
- General and local complications of pneumonia...........
- General Complications: Septic shock, multi-organ failure, and death.
- Local Complications: Parapneumonic effusion, empyema (pus in the pleural space), and lung abscess (cavitation within the area of consolidation)
- Crucial vaccines used for the prevention of pneumonia....Influenza vaccine and Pneumococcal vaccine
Causes of non-resolving pneumonia and treatment failure.........Failure to respond to treatment can be categorized into three areas:
- Incorrect Diagnosis: The condition may actually be a pulmonary drug reaction, heart failure, pulmonary embolism, sarcoidosis, or a neoplasm.
- Host-related factors: The patient may be immunocompromised (e.g., HIV, transplant recipient), the treatment was started too late, or local complications like empyema have developed.
- Pathogen and Drug-related factors: The infection might be caused by a resistant pathogen, an unusual organism (like fungi or TB), or there may be a medication error such as the wrong dose or an antibiotic that does not cover the specific organism (e.g., giving a Gram-positive drug for a Gram-negative infection)
