About This Book

Comprehensive clinical manual detailing disorders of the nervous, genitourinary, ocular, and integumentary systems in domestic animals. It begins with principles of neural control and general symptomatology, classifying motor, sensory, and psychic disturbances and methods for localizing lesions. The text describes specific conditions such as seizures, paralysis, meningitis, intracranial hemorrhage, tumors, and toxicoses, and outlines diagnostic signs and pathological causes. Later sections address urine analysis and renal disease, urinary tract inflammation and calculi, and diseases of the eye, skin, and constitutional systems, combining pathological description with clinical signs, differential diagnosis, and practical guidance for examination and interpretation.

HORDEOLUM. STYE. ACNE.

Like acne of the skin in general, this consists in inflammation and suppuration of a hair follicle and sebaceous gland. The whole lid or a large part of it may be swollen, but by stroking it with the finger, a hard, rounded, very tender spot will be detected and as the disease advances this develops a minute collection of pus. A specially wide orifice favors the entrance of the pus microbes, and the onset of the disease. It has been noted in dogs (Fröhner).

For abortive treatment Fick recommends dry heat from a pocket handkerchief or a heated teaspoon. If pus is present it must be evacuated, and recurrence guarded against by cleanliness and antiseptics. Use pyoktannin solution (1 ∶ 1000), or mercuric chloride (1 ∶ 5000) or yellow oxide of mercury ointment.
