What are the functions of the blood and lymph? State the changes occurring in the circulation in inflamed tissue. What is palpitation? Give the causes and treatment. What are the common causes of pericarditis? Give the causes and treatment of acute lymphangitis. GENERAL DISCUSSION. The nervous system may be divided into central and peripheral portions.
An example of this kind is to be seen in a wound perforating the tibial fascia, where the injury is inflicted by means of a horse being kicked by another animal shod with sharp shoe-calks. Cases of this kind invariably result in a septic lymphangitis, and frequently lymphadenitis also occurs, for the inguinal lymph glands are so situated that their becoming contaminated is almost certain.
However, much depends upon the manner in which the foot in motion strikes the weight-bearing member as to the corrective measures that are indicated. This belongs to the domain of pathological shoeing and the reader is referred to works on this subject for further study of this phase of lameness. Lymphangitis.
This may be a wound or a purulent blister, and the streptococcus pyogenes is the organism most frequently present. Septic lymphangitis is commonly met with in those who, from the nature of their occupation, handle infective material. A gonococcal form has been observed in those suffering from gonorrhœa.
Filarial disease in the lymphatics of the groin appears as a soft, doughy swelling, varying in size from a walnut to a cocoa-nut; it may partly disappear on pressure and when the patient lies down. The patient gives a history of feverish attacks of the nature of lymphangitis during which the swelling becomes painful and tender.
Individual resistance or lowered vitality has a marked influence on the course of this affection. This type of lymphangitis is associated with, or the result of, a derangement of digestion. It affects heavy draft horses, rarely other types of animals, and involves one or both hind legs. Occurrence. In healthy and well nourished horses irregularly used, this affection may suddenly manifest itself.
Subcutaneous rupture of the thoracic duct may result from a crush of the thorax. There are physical signs of fluid in one or other of these situations, but, as a rule, the nature of the lesion is only recognised when chyle is withdrawn by the exploring needle. #Lymphangitis.# Inflammation of peripheral lymph vessels usually results from some primary source of pyogenic infection in the skin.
Excluding glanders, in the majority of instances, lymphangitis in the horse, such as frequently affects the hind legs, is due to the local introduction of infectious material into the tissues as a result of wounds. However, one may observe in some instances an acute lymphangitis which affects the pelvic limbs of horses and no evidence of infection exists.
The trite phrase that "the tissues are bathed in lymph" should make clear the reason for the frequent occurrence of infectious lymphangitis and lymphadenitis.
