Lectures & Topics

Skin Structure & Function Across Species

Histology: epidermis, dermis, hypodermis; hair follicles; glands (sebaceous, sweat, apocrine); species differences in coat structure (feline vs. canine vs. equine skin). Barrier function, pH differences.

Dermatophytosis (Ringworm)

Fungal infections (Microsporum, Trichophyton), transmission, clinical presentation, diagnosis (KOH prep, Wood's lamp, culture). Topical and systemic antifungal therapy. Zoonotic potential.

Allergic Dermatitis & Pruritus

Atopic dermatitis, food allergy, flea allergy dermatitis. Pruritus mechanisms, diagnostic approach (history, intradermal testing, elimination diet), management (allergen avoidance, glucocorticoids, immunotherapy).

Bacterial & Parasitic Dermatitis

Pyoderma (superficial vs. deep), Demodex, Sarcoptes, Otodectes. Diagnostics (cytology, skin scrapings, culture). Treatment selection based on organism identification.

Wound Healing & Tissue Repair

Phases of wound healing (hemostasis, inflammation, proliferation, remodeling). Factors affecting healing (age, nutrition, infection, motion). Wound classification and closure options.

Hooves, Horns, & Special Keratinized Structures

Equine hoof anatomy, navicular disease, laminitis, thrombosis. Bovine hoof disorders, lameness assessment. Horn disorders, skin conditions affecting these structures.

Flashcards

Clinical Case Prep

Case 1: Canine Atopic Dermatitis

3-year-old Labrador presents with severe pruritus (face, ears, paws), recurrent skin infections. History of seasonal symptoms. Intradermal skin testing positive to dust mites and grasses. Discuss atopy management: allergen avoidance, antihistamines, glucocorticoid dosing, immunotherapy indications.

Case 2: Feline Dermatophytosis

2-year-old cat presents with circular areas of alopecia on face and forelimbs. Wood's lamp shows blue-green fluorescence (Microsporum canis). Household includes two children with skin lesions. Discuss zoonotic transmission, topical/systemic therapy, environmental decontamination.

Case 3: Equine Laminitis

5-year-old horse with acute onset severe foot pain and digital pulse prominence bilaterally. Founder lines evident on hooves. Triggered by high-grain diet 3 days prior. Discuss pathophysiology, radiographic assessment, acute management (NSAIDs, ice, support), farrier interventions, prognosis.
