Clinical Information

Cross Infection - Any infection which a patient contracts in a health-care institution.

Latent Infection - Delayed infection of the host by a dormant or inactive pathogen.

Mastectomy - Surgical procedure to remove one or both breasts.

Persistent Infection - Infection which lasts for a long period with continuous display of clinical features. Persistent infection arises due to inability of host cells to clear primary infections completely. When persistent infections are cleared so that infection symptoms are under control they are often referred to as chronic infections. LATENT INFECTIONS are infections in which manifestation of clinical symptoms appear later.

Seroma - Tumor-like sterile accumulation of serum in a tissue, organ, or cavity. It results from a tissue insult and is the product of tissue inflammation. It most commonly occurs following MASTECTOMY.
