Acute Bronchitis
A self-limiting, mostly viral inflammation of the large airways causing a persistent cough lasting 1-3 weeks.
Achalasia

Henoch-Schonlein Purpura
A childhood vasculitis presenting with a purpuric rash on the legs, joint pain, abdominal pain, and kidney involvement.
Allergic Bronchopulmonary Aspergillosis
An allergic lung reaction to Aspergillus fungus seen in asthma and cystic fibrosis patients, causing wheezing, brownish mucus plugs, and eventually permanent lung damage if not treated.
Hypertrophic Cardiomyopathy
A genetic condition causing abnormal thickening of the heart muscle, leading to breathing problems, chest pain, and a risk of sudden cardiac death.
Small Cell Lung Cancer
A very fast-growing, aggressive lung cancer strongly linked to heavy smoking, presenting centrally in the chest and often spreading early to the brain and other organs.
Mitral Regurgitation
A valvular disorder where the mitral valve fails to close completely, allowing blood to flow backward into the left atrium during ventricular contraction.
Recently Updated
Aspergilloma
A ball of fungus that grows inside an old lung cavity (usually from old TB), typically presenting with coughing up blood.
Hairy Cell Leukemia
A rare, slow-growing blood cancer where B-cells develop 'hairy' projections, causing an enlarged spleen and low blood counts, highly curable with specific chemotherapy.
Hypercalcemia of Malignancy
A life-threatening metabolic complication of advanced cancer causing very high calcium levels due to tumor-secreted hormones (PTHrP) or bone metastases.
Basal Cell Carcinoma
A slow-growing, locally destructive skin cancer caused by sun exposure, typically appearing as a pearly bump on the face.
Primary Hyperparathyroidism
A condition where a benign tumor on a parathyroid gland produces too much parathyroid hormone, pulling calcium out of bones and into the blood.

Fibromyalgia
A chronic disorder causing widespread body pain, severe fatigue, and brain fog, stemming from how the brain processes pain.
Asthma
A chronic lung disease causing episodes of airway narrowing and mucus production, leading to wheezing and shortness of breath. Controlled with daily inhaled steroids.
Non-Small Cell Lung Cancer
The most common type of lung cancer, encompassing adenocarcinoma and squamous cell carcinoma, frequently linked to smoking but heavily treated with new targeted and immunotherapies.
Heart Failure with Preserved Ejection Fraction
A type of heart failure where the heart pumps normally but is too stiff to relax and fill properly with blood, causing fluid backup into the lungs and body.
Focal Segmental Glomerulosclerosis
A progressive kidney disease characterized by focal and segmental scarring of glomeruli, commonly presenting as nephrotic syndrome and leading to renal failure if untreated.
Burkitt Lymphoma
An extremely fast-growing blood cancer of B-cells, often presenting as a large jaw or abdominal mass, requiring immediate intensive chemotherapy.
