Diagnostic studies on skin affections in dogs

Abstract

The skin is the largest and most visible organ of the body it is the anatomic and physiologic barrier between animal and the surrounding environment, it provides protection from physical, chemical and microbiologic injury and it’s sensory component perceive heat, cold, touch, pressure and pruritus.in addition the skin is synergistic with internal organ system and thus reflect pathologic processes that are either primary or shared with other organs of the body Almost all dermatology patients have a primary or underlying disease that causes secondary infections. These infections must be eliminated and prevented but will recur rapidly unless the primary disease is identified and controlled. In this study we investigated the primary diseases as well as secondary infections to reach a definitive diagnosis which will lead to proper treatment and cure. 67 dogs were divided into 2 groups. Control group 20 apparently healthy dogs and diseased group 47 dogs. • All dogs were clinically examined, blood samples were collected from cephalic vein and divided into 2 parts: 1- EDTA tube for CBC examination. 2- Plain tube for (ALT,AST, GGT, BUN, creatinine, FT4, TSH and cortisol) examination • Only diseased dogs were subjected to skin scraping and skin biopsy from skin lesions for histopathological examination.
