DISEASES OF THE BLOOD AND DUCTLESS GLANDS.

Anaemia, or Anemia.—­This may be defined as a reduction of the amount of blood as a whole or of its corpuscles, or of certain of its more important constituents, such as albumin and haemoglobin.  Primary or essential anemia includes chlorosis and pernicious anemia; secondary anemia results from hemorrhages, poor nourishment or intoxications, poisons.  Chlorosis, a primary anemia chiefly of young girls, characterized by marked relative decrease of haemoglobin.

Causes.—­It usually occurs in blondes of from twelve to twenty years of age and most often from fourteen to seventeen years of age, when the menstrual function is being established and during which time they are rushed with their school work.  There may be a family history of chlorosis or tuberculosis.  Poor food, hard, unhealthy work, confinement in close unventilated rooms are other causes.

Symptoms.—­Rounded fleshy appearance may continue.  There is some difficulty of breathing, palpitation of the heart on slight exertion, from a fright or from excitement, tendency to faint feeling or even fainting, headache, a tired feeling, hard to stir or do anything, irritable temper, poor or changeable appetite, the digestion is disturbed, there is constipation, coldness of the hands and feet, difficult menstruation, irregular menstruation, leucorrhea, amenorrhea, and sometimes there is a slight fever.  The color is often of a yellowish-green tinge, and this is more noticeable in the brunette type, though the cheeks may be flushed; the whites of the eyes bluish white in color.  The heart sounds are not right.  The blood is pale in color.  The red cells are diminished, but usually are not below eighty per cent of the normal; the haemoglobin is greatly reduced, sometimes to thirty-five or forty per cent.  The age, greenish tint of pallor, bluish whites of the eyes, poor nutrition, etc., aid in making the diagnosis.

Treatment.—­Fresh air, good food, care of the bowels and rest if the symptoms are severe.  When it is not so severe, plenty of outdoor exercise is necessary and beneficial.  That takes them away from their cramped sedentary life and gives the sunshine, good pure air, and change of the scene.  Horseback riding is a very good form of exercise, but it should be slow riding.  “Tending” the horse is also good, and sleeping in the open air is excellent.  Automobile riding is too straining and should not be indulged in.
