=Rheumatic Fever.=--Hard to adjust because of its painful nature. Results of proper adjustment usually, but not always, good. =Rheumatism.=--Muscular rheumatism yields more rapidly than articular. Acute tends to quick recovery, chronic to more or less lengthened and slow improvement. Rheumatic diathesis may require many months of careful adjustment. =Rubella.=--Simply and easily checked. Rash slight, and no prostration at all. =Scarlet Fever.=--Data on quarantinable cases is meagre, but scarlet fever, or scarlatina, seems to be quickly modified by adjustment. One may expect a drop of from one to two degrees in temperature after first adjustment, followed by steady rise, which will again be checked by the next adjustment. Rash appears early, and all symptoms are mild, but several days are often required to put the patient at ease. Occasional sequelae, such as endocarditis, otitis media, or other inflammations, occur unless case be watched with great care. No fatal terminations under adjustment except in cases which were at first misdiagnosed. =Seminal Emissions.=--Prognosis excellent in cases uncomplicated by masturbation or excessive venery; in such cases bad until habits are changed. =Simple Continued Fever.=--Always recovers. Usually drops one to two degrees shortly following correct adjustment, with amelioration of all symptoms. =Smallpox.=--Infections vary in virulence. In temperate climates all phases are hastened by adjustment and tend to recover without sequelae. The milder smallpox due to infection by vaccination is also amenable to adjustment, and prompt handling will often prevent serious poisoning. =Splanchnoptosis.=--Partial or marked relief is usual--and slow. Complete natural replacement of all viscera is the exception rather than the rule. =Splenic Enlargement.=--Variable prognosis according to cause. Secondary enlargements due to systematic infection yield with the disappearance of the infection. Primary enlargements yield more readily as a rule, with exceptions. Malarial spleen is slow to reduce. =Splenitis.=--Prognosis presumably good, but few authentic cases reported. =Spondylitis Deformans.=--Prognosis favorable for slow, slight improvement, but not for complete cure. =Strabismus.=--Excellent in young subjects, less than fair in patients over thirty. =Sunstroke.=--Theoretically curable, but no experience. =Syphilis.=--The primary sore frequently dries under adjustment without the development of any secondary or tertiary stage. If first adjusted during the secondary manifestations symptoms may readily disappear and no tertiary stage ever appear. There are some authenticated cures eight and ten years past without recurrence of any sign. In the tertiary stage the organic lesions do not respond. Prognosis is so hopeless in this stage that it seems useless to apply Chiropractic at all.
