The diagnosis is extremely easy. The prognosis is grave.
Treatment consists in prompt and free bleeding to prevent pulmonary congestion. The animals should be rested in a shady, sheltered spot. They should have cool drinks and be sprinkled over the head, neck, or entire surface of the body with cold water.
To prevent such attacks, fat animals should not be moved for long distances, or during the hottest hours of the day, while difficult and prolonged exertion should be avoided.
CHAPTER VI.
DISEASES OF THE LYMPHATIC SYSTEM.
Diseases of the lymphatics are numerous, highly important, and still imperfectly understood. They follow various accidents, local inflammations, certain specific diseases, such as tuberculosis, and may occur in an isolated form without involving any other part of the body.
Fig. 209.—Superficial lymphatic glands of the head and neck. P, parotid gland; Gl.SM, submaxillary gland; GaSG, subglossal gland; GaPPA, preparotid gland; GaSA, subatloid gland; GaPS, prescapular gland; GaPPE, prepectoral gland; J, jugular; 1re C, first rib.
Inflammation, usually of infectious origin, may attack lymphatic vessels (lymphangitis) or lymphatic glands (adenitis), giving rise either to simple lymphangitis, suppurative lymphangitis, or again to simple or suppurative adenitis.
It is unnecessary to emphasise this point in general surgical pathology, for it is identical with that which is observed in other domestic animals, but in order properly to detect the glandular symptoms in certain diseases peculiar to the lymphatic apparatus, and in certain specific diseases, such as tuberculosis, farcy of the ox, etc., it is necessary to understand thoroughly the topography of the lymphatic system.
Topography of the lymphatic glandular apparatus: Examination. The lymphatic glands are in some cases superficial, in others deep seated, and are arranged symmetrically on either side of the body.
