=Nutrition and Growth.=--The general nutrition suffers in scurvy as the disease progresses. It is a mistake, however, to picture the scorbutic individual, either adult or infant, as in a state of malnutrition. Not infrequently he appears well nourished, an appearance which is heightened by the slight edema of the face. Infants generally for a period of weeks or months preceding the onset maintain a stationary weight. This may be the only sign of the scorbutic condition. For example: An infant seen in 1915 gained about one-half a pound during the months of February, March, April and May. At this time it was somewhat over 9 months of age and had never received raw milk or other antiscorbutic food. In June it was given orange-peel juice, and gained 2 pounds within a month. There were no other scorbutic signs or symptoms, and no loss of appetite during the months of February and March, although the baby was suffering from a progressive scurvy. The growth impulse of the body throughout an attack of scurvy remains unimpaired, being merely in an inactive or quiescent state. Fig. 14 shows this very well, demonstrating that when an antiscorbutic food is added to the dietary the gain may be abnormally great--there may be supergrowth. Generally such marked increases are due to an increase in the consumption of food, following the stimulation of the appetite. However, decided gain in weight may follow the giving of orange juice or other antiscorbutic despite the fact that the intake of food is maintained at the same level. [Illustration: FIG. 24.--Development of scurvy in spite of normal gain in weight in a baby who had been underfed since birth.] Although it may be stated as a principle that the development of scurvy is accompanied by a failure to gain in weight, there are exceptions to this rule. Under certain conditions the weight may follow a perfectly normal course during the entire period. Fig. 24 illustrates this clinical paradox: A baby was seen in January, when it was 7½ months of age. Toward the end of February, in spite of constant and normal gain in weight, he manifested unmistakable signs of scurvy--peridental hemorrhage over the upper incisor teeth, which were erupting, and tenderness of the lower ends of the femora. The scorbutic nature of these signs were substantiated by their prompt subsidence on the administration of orange juice. We explain the phenomenon as follows: This baby had been starved in a two-fold sense throughout the first months of its life--it had received a diet lacking in caloric value as well as deficient in antiscorbutic vitamine. Its growth impulse had been held in abeyance for months by both of these factors. When sufficient calories were supplied in the dietary, growth was no longer repressed, and a steady gain resulted in spite of the continued inadequacy of the antiscorbutic factor.
