In healthy men and women, urine does not contain any blood that can be seen with the eye, called "gross blood," nor does it contain red blood cells that can be discovered with the aid of a microscope.

In adult men, enlargement and/or infection of the prostate, bladder infection and...

Sinusitis is usually due to allergies or infection. When sinusitis keeps coming back or continues for a long period of time, it is considered chronic. Causes of chronic sinusitis include a deviated nasal septum or other blockage of the nose that can trap fluid in a sinus. Dental infections such as tooth abscess may spread into the sinus and also lead to chronic sinusitis. Allergy to the aspergillus species of fungus appears to ca...
