Can you please describe the difference and symptoms between sinusitis, eosinophilia and bronchitis?

Separate entities: Sinusitis is a disease characterized by inflammation of the sinuses. Eosinophilia is a condition characterized by extra eosinophils, a type of white blood cell. Bronchitis is a disease characterized by inflammation of the bronchi, the smaller breathing tubes leading to the lungs. These are all separate entities and can exist together or separately.
