Cause.—The disease is believed to be directly due to a deficiency in the diet of the antiscorbutic vitamine, known as “Water soluble C.”
Treatment.—For many years it was known that lime juice exerted a curative effect upon scurvy. But recently the efficiency of this fruit juice has proved to fall far short of that effected by either orange, or tomato juice.
Feeding experiments have proved that animals, fed upon rations consisting of dry food without the addition of green, will develop scurvy. And that the milk of such animals will show a deficiency in the “C” vitamine which will lead to a development of the disease in infants fed upon such milk.
Milk is, in fact, by no means a perfect food, so far as its vitamine content is concerned. First, because the presence of the vitamine in milk is so dependent upon the diet of the mother or the animal, second, because the pasteurization temperatures used to insure cow’s milk of purity from a bacterial standpoint, destroys in it the greater part of its antiscorbutic power. Either of which makes it necessary to supplement the formula of the artificially fed infant, and, in case of the former, the mother’s milk of the breast-fed baby, with orange, or canned tomato juice.
The amount of either of the fruit juices which is necessary to insure the child of a freedom from scurvy, is small, ranging from one-half to one ounce of strained juice daily, this amount is increased gradually until the child is taking from one and one-half to two ounces each day. It has been found advisable to administer the fruit juice between the two morning feedings. As a rule, the fruit juices are given at the beginning of the seventh month, but they may be given at a much earlier date, the time being adjusted by the physician.
RICKETS
Rickets, like scurvy, is being discussed by scientists both in America and abroad. The disease is widespread, particularly in its subacute form, and its effect upon the health of the child is so serious that no amount of effort to prevent its development should be considered too great.
Calcium Retention in Rickets.—The disease is characterized by a failure of the bones to lay down lime salts, this failure causes a softness and flexibility in the structure of the bones which permits them to bend into deformities. Then, too, it is a well established fact that any interference with the calcium metabolism in the body, will inevitably bring about disaster. (See Mineral Metabolism, page [185].)
Factors Inducing Rickets.—According to Dr. Eddy, “It is impossible at present to determine whether rickets is a true avitaminose or a consequence of deficiency in a series of factors.”
Treatment.—For breast-fed babies it is necessary to adjust the diet of the mother to include more of the vitamine bearing foods, since milk contains vitamines only in proportion to the amount eaten in food. For artificially fed children, the giving of cod liver oil has recently been adopted as the surest and safest method of curing and preventing the development of the disease. Like treatment is used with breast-fed infants if the need arises.
