Relapsing polychondritis (RP) is a rare inflammatory multiorgan disorder affecting cartilaginous structures and other connective tissues. Serious cardiovascular complications have been reported in patients with RP, the most frequent being aortic or mitral regurgitation and aortic aneurysms. Aortitis is a very rare complication. An unusual case of active aortitis in a patient with RP, despite in...

BACKGROUND Skin infections due to Staphylococcus aureus have recently become a public concern, mainly because of emerging resistance against widely used antibiotics and specific virulence determinants. Strains harboring the lukS-lukF gene (which codes for Panton-Valentine leukocidin) are frequently associated with severe furunculosis. Generally applicable strategies for the control of community...

Tick-borne relapsing fever in western North America is a zoonosis caused by the spirochete bacterium, Borrelia hermsii, which is transmitted by the bite of infected Ornithodoros hermsi ticks. The pathogen is maintained in natural cycles involving small rodent hosts such as chipmunks and tree squirrels, as well as the tick vector. In order for these ticks to establish sustained and viable popula...

BACKGROUND Bee sting therapy is increasingly used to treat patients with multiple sclerosis (MS) in the belief that it can stabilize or ameliorate the disease. However, there are no clinical studies to justify its use. METHODS In a randomized, crossover study, we assigned 26 patients with relapsing-remitting or relapsing secondary progressive MS to 24 weeks of medically supervised bee sting t...

Relapsing polychondritis (RP) is a rare disease characterized by recurrent inflammation and destruction of the cartilaginous structures. Tracheobronchial chondritis is a dreaded complication of RP. We wish to report a case of RP of the trachea and bronchi which was treated with nasal continuous positive airway pressure.

Relapsing polychondritis is an autoimmune disease in which an inappropriate immune response destroys cartilage. Cartilage of the ears, larynx and nose rather than spine and joint cartilage is affected by a chronic relapsing and erosive inflammation. Several animal models for relapsing polychondritis have been published in which immunization with various cartilage proteins induces a variety of c...

Ticks (Ixodidae and Argasidae) are important arthropod vectors of various pathogens that cause human animal infectious diseases. Many previously published studies on tick-borne focused those transmitted by ixodid ticks. Although there increasing reports viral associated with argasid ticks, information bacterial they transmit is scarce. The aim this molecular study was to detect characterize Ric...
