Dr. Preziosi deals with diseases that affect the skin, ears, and sometimes the gastrointestinal system. This can range from allergies to endocrine diseases, resistant infections, congenital skin disorders, autoimmune skin diseases, unusual infectious diseases, and even some skin cancers.
To aid in the diagnosis of these various disorders she may employ skin or ear cytology, culture of the infection, blood work, or skin biopsies. Treatment of skin cancer is usually limited to cutaneous lymphoma, melanoma, and select cases of mast cell tumors. For allergies, she will help clients through food trials or if appropriate, perform intradermal skin testing and formulate allergy serum based on the results.
She is available to refer veterinarians for consultation on using serum test results or can make up an allergy serum that reflects the local allergens. For dogs with chronic ear disease, she will often be able to clear disease using a combination of long-term treatment, deep ear flushing using video otoscopy, and diagnosis of the underlying cause.
