=Pleurisy.=--Pleurisy, unless purulent or tubercular, yields well in varying periods. Purulent and tubercular pleurisy are stubborn and may not recover. =Pneumonia.=--The author has had a wide and gratifying experience with pneumonia. At every stage it seems amenable to adjustment, and the usual effect of the first adjustment is a drop of from one to two degrees in the temperature with immediate softening of the consolidated area. Specific adjustments get best and quickest results. Pneumonia should =always= recover, unless it occurs as an intercurrent event in some chronic and wasting disease, as Bright’s Disease. =Potts’ Disease.=--Tubercular caries of the bodies of the vertebrae is curable, within limits. Occasional cases are seen in which Nature has stopped the spread of the disease by walling off the morbid area with exostosis. Such cases should not be adjusted, and the disease may remain latent through a long life. When active the disease proves fatal unless checked, which is possible in the earlier stages, and becomes impossible when the vertebral bodies are too fragile to stand strong adjustments. Discernment in case-taking will avoid any fatalities under adjustment, but by no means all cases of Potts’ Disease are curable. =Pregnancy.=--We may correct by adjustment any pathological conditions arising during pregnancy which would be amenable to adjustment under other conditions. A course of adjustments during a normal pregnancy will render delivery easier and lessen, but not abolish, the pains. Great care must be exercised in the manner of adjustment. =Prostatic Enlargement.=--Varies according to age and recuperative power. Prognosis is bad in the very aged and infirm, but in more vigorous subjects quite good for steady reduction of the hypertrophied gland, with subsidence of attendant symptoms. Venereal history is unfavorable. =Pulmonary Tuberculosis.=--In the early stages, where little damage has been done to lung tissue, recovery is rapid and quite certain. In fully developed cases, with characteristic symptoms and marked damage to tissue, prognosis is very grave, and it is usually wisest to advise a trip to the Southwest in preference to adjustments. Tubercular cases should be studied with a view to estimating the exact condition and recuperative power of the patient before taking. =Rachitis.=--Prognosis excellent. In a period varying from six months in the best to five to seven years in the slowest cases, all show complete or nearly complete cures. All deformity may be checked in a short time and proper bone nourishment established. Correction of deformities existing prior to adjustment is a growth process. Too many cases become discouraged at the slowness of the work and stop adjustments. =Retinal Hemorrhage.=--Prognosis fair. Undoubted cures have been recorded, as well as a few failures. At least one case of hemorrhages followed by partially detached retina has been cured, or nearly so, by adjustments.
