Community-Acquired MRSA (CA-MRSA)
Among the most common causes of infection outside health-care institutions, community-acquired methicillin-resistant Staphylococcus aureus (Community aquired-MRSA) most often affects the skin and soft tissues. Besides causing significant morbidity, community-aquired MRSA is increasingly associated with serious and often fatal necrotizing pneumonia or fasciitis, endocarditis, and sepsis. The authoritative links on this resource help you to keep up to date with new diagnostic tests and treatments for community-aquired MRSA, as well as the latest news about local outbreaks and infection control strategies.

Benign skin lesions can arise in the outer ear as easily as in any other body part frequently exposed to the sun. Seborrheic keratosis may mimic malignant melanoma but is innocuous. Actinic keratosis is premalignant and should be excised, biopsied, and the site of excision monitored vigilantly.
All Ears: Auricular Seroma and Pyogenic Granuloma

These innocuous lesions of the outer ear may arise spontaneously or after trauma or surgery. Both auricular seroma and pyogenic granuloma usually resolve satisfactorily after minor surgery, though they may recur.
