Study Notes
Pulmonary Edema
- Pulmonary edema is fluid buildup in the alveoli, often due to left heart failure.
- Non-cardiac causes include ARDS, TRALI, and increased pulmonary capillary hydrostatic pressure.
- Symptoms include shortness of breath, bilateral crackles, and low oxygen saturation.
- Diagnosis is often aided by chest X-rays or CT scans
- Acute respiratory distress syndrome (ARDS) is likely if the PaO2/FiO2 ratio is below 300.
- This is a significant indicator for unilateral conditions.
- Bilateral chest infiltrates can occur from several causes, including pancreatitis, aspiration, toxic shock syndrome, near-drowning, and trauma.
- TRALI (Transfusion-Associated Lung Injury) presents within 6 hours of transfusion.
- Mechanism is abnormal neutrophil priming in response to cytokines in the blood products.
- TACO (Transfusion-Associated Circulatory Overload) occurs more than 6 hours post-transfusion.
- This is a type of cardiogenic pulmonary edema, where the left heart struggles with the increased volume and transudation into the alveoli.
Pneumonia
- Lobar pneumonia, commonly associated with Streptococcus pneumoniae, often presents with a right lower lobe consolidation, and dullness to percussion.
- Bilateral interstitial pneumonia, particularly in immunocompetent patients, is often associated with Mycoplasma.
- Pneumocystis jirovecii pneumonia (PJP) is a specific concern in HIV/AIDS patients with bilateral interstitial/ground glass pneumonia.
- Identifying the specific organism requires careful consideration of patient history and clinical presentation.
- Bacterial pneumonia following influenza is often caused by Staphylococcus aureus.
- Patient presenting with pneumonia and hyponatremia/diarrhea can likely be infected by Legionella.
- If a patient has pneumonia in conjunction with recent air-conditioning exposure, consider Legionella as a possible cause.
- Pneumonia in infants, newborns, and young children has different etiologies and should be diagnosed with the appropriate pathogen in mind.
Bronchiolitis, Bronchitis, and Croup
- Bronchiolitis, frequently found in infants under 18 months, is often caused by respiratory syncytial virus (RSV).
- Laryngotracheal bronchitis (croup), presenting in older children, is typically characterized by a hoarse, barking cough, and a steeple-sign on X-rays.
- Treatment is generally supportive and not pharmacological unless life-threatening.
Epiglottitis, Bacterial Tracheitis, and Pertussis
- Epiglottitis, a relatively rare illness, is a serious infection that obstructs the airway.
- Bacterial tracheitis is characterized by a viral URTI followed by stridor, unlike epiglottitis by the ability to open the mouth.
- Pertussis, whooping cough, is characterized by a succession of coughs followed by an inspiratory stridor. Hygeglycemia or postoperative emesis is a prominent indicator.
Pleurodynia
- Pleurodynia is a viral infection exhibiting sharp or lateral chest pain attributed to intercostal muscle spasms.
Pulmonary Abscess
- Pulmonary abscess is frequently caused by a foreign material/aspiration of oropharyngeal bacteria.
- The presence of "foul-smelling sputum" is typical in abscesses and points to aspiration of anaerobic bacteria (Bacteroides).
Acute Bronchopulmonary Aspergillosis (ABPA)
- This condition is identified by an Asthma-like presentation coupled with fever and hypersensitivity to aspergillus.
Cryptogenic Organizing Pneumonia (COP)
- A condition that presents like pneumonia.
- A restrictive lung disorder that does not respond to antibiotics.
Otitis Media (OM)
- OM is an inflammation of the middle ear and commonly caused by streptococcus pneumoniae).
- Serous OM is characterized by fluid behind the tympanic membrane.
- Tympanic membrane perforations are usually followed by otalgia.
Sinusitis
- Sinusitis is indicated by lingering URTIs lasting beyond 10 days.
- It is often caused by Streptococcus pneumoniae or other bacteria that cause upper respiratory infection complications.
- A CT scan with or without nasal endoscopy is useful if the condition has prolonged symptoms (more than 12 weeks).
Tuberculosis
- Tuberculosis (TB) is a bacterial infection that primarily affects the lungs.
- Key symptoms include fever, night sweats, weight loss, and hemoptysis.
- Diagnosis starts with a PPD skin test.
- If PPD is positive, chest x-ray proceeds, followed by treatment based on the test results.
Hot Tub Lung
- Hot tub lung is an infection associated with breathing in fumes, such as Mycobacterium avium complex (MAC).
Other Diseases
- Specific information on other diseases (e.g., Coronavirus, Influenza) wasn't included in this portion, so more info is needed.
- Discussions on pediatric topics (e.g., tracheoesophageal fistula, choanal atresia) are related to their respective categories.
