Diagnosis Diagnostic Difficulties in Community-Acquired Pneumonia (CAP). It is important to determine whether the cause of CAP is a bacterium, atypical bacterium, or virus, because they require different treatments. In children, for example, S. pneumoniae is the most common cause of pneumonia, but respiratory syncytial virus may also cause the disease. Although symptoms may differ, they often overlap, which can make it difficult to identify the organism by symptoms alone. The cause of CAP is found in only about half of cases. Nevertheless, in many cases of mild-to-moderate CAP, the physician is able to diagnose and treat pneumonia based solely on a medical history and physical examination.

It is mistaking your synovial linings around your joints as an enemy of your body. As it is programmed to do, your immune system attacks this lining and as it slowly erodes the lining you also begin to lose cartilage, and finally bone. (this is a VERY simplified explanation) There are many different parts of the immune system that may be at fault with RA, T cells, B cells, TNF, IL-6 and IL-1 are only a few....
Definition Percussion is a method of tapping body parts with fingers, hands, or small instruments as part of a physical examination.
