Pastern Dermatitis
Pastern dermatitis, or “Mud Fever,” is a chronic, multifactorial dermatitis of the palmar/plantar aspect of the pastern in horses. Various factors can contribute, including bacteria such as Staphylococcus or Dermatophilus congolensis, fungi, mites, UV radiation, chemical irritants, and immune imbalances, with moisture being a predisposing factor. Clinically, pastern dermatitis is characterized by crust formation, exudation, alopecia, hyperkeratosis, fissures, and pain, and it more commonly affects white pasterns due to photosensitization.
Treatment aims at eliminating underlying causes by optimizing husbandry and avoiding irritants. Symptomatic treatment includes removing crusts after soaking and washing. As an antiseptic, hypochlorous acid (HOCl) has proven effective due to its broad spectrum of activity and good tolerability. Povidone-iodine can be used as an alternative. Local antibiotics or antifungals, as well as anti-inflammatory agents, are used as needed. In cases of systemic involvement, systemic antibiotics are necessary based on an antibiogram. Consistent hygiene and a dry environment are crucial. The prognosis is variable, depending on the cause and consistent implementation of therapy, with recurrences being common.

Etiology, Diagnosis, Therapy and the Role of Hypochlorous Acid (HOCl) Equine keratitis is one of the most common and clinically significant ophthalmic diseases in horses. Due to the prominent position of the equine eye and the horse’s heightened inflammatory response, corneal disease can progress rapidly and may lead to permanent visual impairment or loss of the globe if not treated promptly.
