What podiatrists need to know about dermatopathologists

2021-03-09T14:30:28-05:00

Q&A with two Bako Diagnostics dermatopathologists: Kim Whisenant, M.D., and Carolina Montes, M.D. on partnering with podiatrists Q. What is the importance of podiatrists being familiar with pathology, specifically dermatopathology? A. Dr. Montes: The skin is the largest organ of the body, and many medical specialties, including podiatry, come in contact with disorders of the skin. Lesions that appear on the skin, including the foot, can also be a manifestation of internal systemic disease. Consequently, it’s important for clinicians to be familiar with both inflammatory and neoplastic processes of [...]

Overview: Green Nail Syndrome

2021-02-17T17:27:31-05:00

Green nail syndrome (GNS) is the most common bacterial infection of the nail unit. Green nail syndrome (GNS) is the most common bacterial infection of the nail unit. Both the upper and lower extremities may be affected in GNS, but is uncommonly reported as a primary cause of onychodystrophy. The causative organism, Pseudomonas aeruginosa, is a gramnegative bacteria which is ubiquitous in nature favoring warm and moist environments with reservoirs in soil, water, plants and animals. Infection of the nail results in chloronychia as a direct result of the production of pyoverdin and pyocyanin by P. aeruginosa. BakoDx DNA [...]

Biopsy Planning and Post-Biopsy Tissue Handling : A Synopsis

2017-11-24T19:22:22-05:00

Introduction As a general rule, the podiatic profession is notorious for its underutilization of cutaneous and soft tissue biopsy techniques. In some instances, such under-use may be attributed to trepidation stemming from a lack of familiarity with the biopsy techniques themselves; however, I believe this is not the preeminent cause. In my experience, the most common reason that many podiatric clinicians don’t use biopsy techniques to their fullest is a degree of insecurity regarding when to use witch biopsy and what to do with them once the biopsy has been performed. In most offices, the support staff is ill prepared [...]

Cutaneous Biopsy Techniques in the Management of Chronic Wounds

2017-11-24T19:32:38-05:00

Many clinicians rely exclusively on clinical acumen when determining how to manage chronic wounds. Though an ulcer’s clinical features may be fairly indicative of its etiology, in some instances, such is not the case. Even among the most characteristic‐appearing ulcerations, masqueraders do exist. Ruling out the possibility of an unsuspected neoplastic or inflammatory condition could be necessary for the successful management of chronic wounds. In this context, cutaneous biopsy techniques may be invaluable; however, their utility does not necessarily end here. There are three common clinical settings in which a biopsy may be used in the management of a chronic wound. [...]
