Furthermore, in laminitis there is an elevation of the temperature, an almost invariable indication for aconitin.
Strangles or distemper is, according to most pathologists, due to the Streptococcus equi. Hoare states that in this type of specific arthritis the contagium is probably carried by the blood. He gives it as his opinion that even laminitis has occurred as a result of the streptococcus-equi. This, indeed, would point toward probable extension by the blood as well as by way of lymph vessels.
If this is impossible, poulticing the feet or standing the animal in moist clay will help in relieving the soreness. Excessive cutting away of the horny sole is contra-indicated. Suppurative corns should be given proper drainage and treatment. LAMINITIS, "FOUNDER." This is an inflammation of the sensitive or vascular stricture of the foot. The inflammation may be acute, subacute or chronic.
All body cells exert this selective action in the assimilation of food, the tissue needing most any particular kind of food circulating in the blood, gets it. Our first consideration in laminitis should be to remove the cause to stop the absorption of the toxin in the intestinal tract that is producing the condition.
When the subject is caused to walk, symptoms of excruciating pain are manifested in all acute cases of laminitis. In some cases where all four feet are affected, no reasonable amount of persuasion will cause the suffering animal to move from its tracks. There is acceleration of the rate of heart action; the pulse is full and in some cases, bounding.
This grouping does not include the effect of direct injuries of any and all kinds to which the feet are subjected such as: Concussion in fast road work, injuries occasioned by tight or ill fitting shoes, contusions of any kind resulting in non-infectious inflammation of the sensitive laminae, as well as the causes which produce laminitis where weight is borne by one foot when its fellow is out of function.
D.M. Campbell in a discussion of laminitis has the following to say regarding the treatment of such cases: Because superpurgation may be followed by laminitis, the advisability of using the active hypodermic cathartics is questioned. Neither arecolin nor eserin can cause superpurgation.
The prognosis depends on the character of the inflammation and the promptness and thoroughness of the treatment. Acute laminitis may respond to prompt, careful treatment in from ten to fourteen days. Subacute laminitis responds readily to treatment. The prognosis is least favorable in the chronic form. The preventive treatment is very important.
The causes of laminitis are overfeeding, sudden changes in the feed, drinking a large quantity of water when the animal is overheated, overexertion, exhaustion and chilling of the body by standing the animal in a cold draft. It may be associated with such diseases as rheumatism, influenza and colic. The symptoms vary in the different forms of the disease. Pain is the most characteristic symptom.
D.M. Campbell, the effect of toxic materials, which may be absorbed from the digestive tract or the uterus in parturient females, upon the vaso-constrictor nerves, is such that a passive congestion of the sensitive laminae occurs and laminitis is the result.
