Acne vulgaris is a common inflammatory skin condition caused by blocked hair follicles and oil glands, leading to pimples, blackheads, and cysts.
Acute Coronary Syndrome
Acute Coronary Syndrome is a heart attack or severe angina caused by a sudden blockage in a coronary artery, cutting off blood and oxygen to the heart muscle.
Acute Bronchitis
A self-limiting, mostly viral inflammation of the large airways causing a persistent cough lasting 1-3 weeks.
Achalasia
Achalasia is an esophageal motility disorder caused by nerve degeneration, resulting in failure of the lower esophageal sphincter to relax and progressive difficulty swallowing.
Acute Cholecystitis
Acute inflammation of the gallbladder, mostly due to gallstone obstruction of the cystic duct, causing severe right upper quadrant pain.

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.
