Abstract
The skin is the largest and most visible organ of the body and the anatomic and physiologic barrier between animal and environment. It provides protection from physical, chemical, and microbiologic injury, and its sensory components perceive heat, cold, pain, pruritus, touch, and pressure. In addition, the skin is synergistic with internal organ systems and thus reflects pathologic processes that are either primary elsewhere or shared with other tissues.
The present work included 2 studies 1st study (epidemiological study) and 2nd study (clinical study).
