Sarcoidosis: diagnosis, organ risk, and treatment
Connect granulomas to lung findings, calcium abnormalities, and organ injury, then choose diagnostic tests and treatment without overcalling sarcoidosis.
Centriacinar vs Panacinar Emphysema
Compare centrilobular and panacinar emphysema by acinar involvement, lobar distribution, cause, and the stem clues that separate them on board questions.
Asthma and COPD
Distinguish variable airway disease from persistent obstruction, interpret lung tests, and tailor asthma and COPD treatment to risk and physiology.
Secondary Spontaneous Pneumothorax in COPD
Allergic Rhinitis and Upper Airway Cough Syndrome
Lung abscess: follow the route, locate the collection
Connect aspiration, cavity formation and imaging to choose appropriate treatment, interpret recovery, and recognize obstruction, pleural infection and bleeding.
Pneumonias: from airspace findings to targeted care
Connect lung findings, host defenses and microbiology to pneumonia treatment, then reassess aspiration, immune risk, resistance and pleural complications.
Hypersensitivity Pneumonitis: Farmer's Lung & Normal IgE
Hypersensitivity pneumonitis for clinical practice: type III plus type IV reaction to inhaled organic antigen, NORMAL IgE, serum precipitins, restrictive PFTs, and why it is not aspergilloma. Fully interactive.
ARDS and the lung that needs protection
Connect alveolar injury to shunt, Berlin and global definitions, protective ventilation, prone positioning, fluid decisions, and escalation in ARDS.
PE and DVT from probability to treatment
Trace venous clot to pulmonary vascular obstruction, choose probability-based testing, assess right-heart stress, and individualize VTE treatment.
Acid-base disorders
Read blood gases as physiology, check compensation and hidden mixed disorders, and connect anion gaps, renal handling, and urgent treatment decisions.
Pulmonary Physiology: Air, Blood and Pressure
Follow air, blood and pressure through working lung models, then solve clinical cases that distinguish ventilation, gas transfer and oxygen carriage.
Lung cancers: tissue, physiology, and treatment decisions
Learn how lung-cancer histology, ectopic hormone secretion, and thoracic anatomy create classic board patterns; then stage and profile the tumor to choose treatment.
Solitary Pulmonary Nodules and Lung Cancer Red Flags
Tension pneumothorax
Connect pleural pressure to respiratory failure and obstructive shock, recognize urgent deterioration, and select effective decompression and reassessment.
Cystic Fibrosis
Trace CFTR dysfunction through airway disease, salt loss and maldigestion, then interpret diagnostic tests and choose function-directed treatment safely.
Squamous lung carcinoma: tissue, calcium and local anatomy
Squamous cell lung carcinoma: central location, smoking, keratin pearls and intercellular bridges, and PTHrP-driven hypercalcemia, with interactive pathology.
