Nothing is more gratefully appreciated by the little patients than air. May it never be forgotten that night-air is better than foul air, and that furnace-air means air greatly modified by injurious additions. More than twenty years ago I was in occasional attendance upon a male baby--now a medical man of some promise--with craniotabes and a number of general convulsions. No treatment would remove, or even relieve, the attacks, until, without the physician's advice, the father took the baby into the street in the hardest winter weather. After the first long absence from his furnace the baby was well of his convulsions, and the physicians profited by their involuntary experience.
In the same way that salt-bathing is beneficial, so is sea-air. A summer at the seaside is a great blessing to rachitical children. Sea-baths have been arranged for them in France (Berx-sur-mer), in Italy (San Ilario di Nervi, Viarreggio, Livorno, Volti, Fano), in England (Margate), in Germany (German Sea, by Prof. Beneke), and for some little time past in the neighborhood of our own large cities.
{ 164} Complications command great attention in rachitis, particularly where there is danger from the affection of the nerve-centres, for the slightest irritation in some distant part of the body may give rise to an outbreak. Thus, in craniotabes it is desirable to watch even the gums. Not sharing the etiological superstition which attributes so many diseases of infancy to dentition, I still know that a slight irritation of the gums may suffice to exhaust the slim resisting power of the infant. If there be local swelling and congestion of the gums over a growing tooth, it may become necessary, or at least advisable, to lance. An otitis which under ordinary circumstances would give rise to no symptoms at all besides some inconvenience or slight pain will prove the source of great danger in a rachitical (craniotabic) infant. The chronic bronchial catarrh and frequent broncho-pneumonia of such patients require early attention, for they and the neighboring lymphatic glands stand too much in the relation of a vicious circle of cause and effect.
