FACIAL EXPRESSION
The expression of the face varies with the disease. In whooping cough and measles the face is swollen and somewhat flushed, giving the child a heavy, stupid expression. There is also swelling of the face, especially about the eyes, in Bright's disease. Repeated momentary crossing of the eyes often indicates approaching convulsions. In very severe acute diarrhea it is astonishing with what rapidity the face will become sunken and shriveled, and so covered with deep lines that the baby is almost unrecognizable. The same thing occurs more slowly in the condition commonly known as marasmus. Often the face has an expression of distress in the beginning of any serious disease. If the edges of the nostrils move in and out with breathing, we may suspect some difficulty of respiration, such as attends pneumonia. The baby sleeps with its eyes half open in exhausted conditions or when suffering pain.
