Nail infections.

Nail infections are and will continue to be a diagnostic and therapeutic challenge to all foot physicians. Attention to basic concepts of accurate detailed history and physical examination will aid in the determination of the etiology of these infections. Following basic guidelines of incision and drainage, gram stain, soaks, and antibiotics will be the cornerstone of initial treatment of pyogenic infections. Upon resolution of the acute infection a permanent treatment plan can be constituted based on the etiology. Nail infections of mycotic nature require an understanding by both patient and doctor as to the difficulty and resistance to treatment of this problem. It is the authors' opinion that aggressive persistent treatment will provide the best long-term result when dealing with mycotic infections. This may require nail removal, local and systemic treatment as well as change in shoe environment. As we have seen and is stated throughout this text, the nail and its pathologic processes can be a mirror of systemic disease. Many times a dystrophic infected nail may be the initial clinical presentation of a much more involved disease process. It is the responsibility and duty of all foot physicians to have a total understanding of knowledge of normal and pathologic process that affect the nail plates, nail bed, and surrounding nail proper. I hope this article will stimulate the foot physician to approach the disease of the nail with a high index of suspicion and respect.
