Impotence.—Variable outlook, according to secondary causes and pathology. Previous venereal disease renders the prognosis most doubtful. Nervous or vascular impotence is likely to respond well. If due to cord disease, the prognosis is to be made on the original disease.
Influenza.—Mortality not more than 2 per cent, and that in the very aged and infirm. Duration varies greatly. May yield at once, first adjustment being followed by disappearance of fever, profuse perspiration, and completed convalescence in from twenty-four to forty-eight hours; or may require several adjustments at frequent intervals to break fever.
Insanity.—No accurate tabulation of results in different forms of insanity has been made. Numerous successes, interspersed with fewer failures, have been reported. The author has both succeeded and failed with acute dementia, but the failure was a twenty-four-hour trial only, and included but three adjustments.
Intestinal Obstruction.—The prognosis of intestinal obstruction from intussusception or strangulated hernia is, under Chiropractic, bad. Such cases are almost surely fatal unless operated. Faecal obstructions or masses of worms, also volvulus, respond quickly and prognosis is good. Careful diagnosis is required before taking a case of apparent complete obstruction.
Irritable Heart.—If purely nervous, recovery is quick and easy. If there is a drug diathesis or organic disease, slow and doubtful.
Jaundice.—Yields readily, but if of the obstructive form the obstruction must first be reduced or removed by adjustments.
Laryngitis.—A few adjustments suffice for simple acute cases. Specific laryngeal infections are more difficult. Laryngitis with ulceration, which is either syphilitic or tubercular, may not recover or may recover after a protracted struggle. Chronic laryngitis of other forms is curable, but requires more time than acute.
Leucorrhoea.—Fair prognosis only.
Lumbago.—Good, unless pain prevents proper adjustment. True lumbago is quick to respond.
