=Method of Examination.=—For use in nasal examinations and treatment, a suitable chair with adjustable headrest is of much value because if the patient is not comfortable and in a convenient position, the work is very difficult. A few instruments, such as the following, are very essential: A sterilizer for instruments, head mirror and reflecting lamp, nasal speculum, tongue depressor, tonsil pillar-retractor, a nasal packing forceps and a few aluminum cotton applicators. These instruments are few and comparatively inexpensive, but are of more practical value than a lifetime collection of electrical apparatus. Any physician can readily learn the use of these instruments and the methods of examination by attending the clinical sessions of our conventions. Methods and technic of treatment, however, require much practice and experience to develop efficiency. Acute Rhinitis This disease, commonly known as a “cold in the head” is one of the most common, and because of the complications which so commonly result, a disease which really requires careful consideration. =Etiology.=—The predisposing cause is reduced resistance and individual susceptibility to air-borne irritants and infective organisms. Direct exposure of some insufficiently protected part of the body such as the feet in cold, damp weather, exposure of some unprotected part of the body to draughts or exposure of the whole body to slightly reduced temperature for a considerable time, are the common causes. In cold weather, it is very important that the proper indoor humidity be maintained, because the drying of the mucous membranes renders them susceptible to infection. This disease is not only contagious at times but may even become endemic from some specific and virulent organism. The complications which may and often do follow such infections are laryngitis, bronchitis, pneumonia, etc. and any one or more of the focal infections, such as sinuitis, tonsillitis, or middle ear infection. A focal infection thus caused may become chronic and render the patient constantly susceptible to head colds. In fact in those persons who suffer from chronic head colds, there may nearly always be found some focal infection, such as the above named, and it is often impossible to get permanent relief until such sources of focal infection have been properly treated. The influence of gross structural lesions, osteopathic lesions of the cervical and upper thoracic region, vertebræ and ribs must not be overlooked because they exert a powerful influence upon the blood supply, particularly the venous and lymphatic drainage and upon the autonomic nervous mechanism, which regulates the physiologic control of such functions. Gross structural abnormalities of the intranasal chambers, such as deflected septum, enlarged turbinates or cellular turbinates, which cause deficient or abnormal breathing space, may cause and maintain head colds.
