=Dengue.=—_Synonyms._—Break-bone fever; dandy fever; broken-wing fever. _Definition._—An acute, specific, infectious, non-contagious fever, occurring epidemically in tropical and subtropical climates and characterized by two severe paroxysms of fever, separated by an intermission, great muscular pain, and usually attended by an eruption. _Cause._—The nature of the infection or contagion is not known. That it is infectious is shown by the rapidity with which it spreads when once it invades a section. In 1885, within a few weeks, sixteen thousand, in Austin, Texas, were stricken. Neither age, sex, race, nor position exert an influence in staying the disease. _Pathology._—As few cases prove fatal, but little opportunity has ever been given to study its pathological character. There has been found infiltration of the tissues about the joints. It is rare for a case to end fatally, only few succumbing to its influence. For this reason the embalmer will not have many of these cases to treat. _Treatment._—As this rarely comes excepting in the epidemic form, that form will be treated on. The body should be washed with a good germicide, and all openings should be closed with absorbent cotton. The body should then receive a very heavy arterial injection, with drainage of blood, and cavity injection. As is the case in epidemics, the body should be buried as soon as possible. While the mortality is light, yet the most strenuous treatment should be given to assist in the campaign of the health authorities against the disease and its spread. When more is known about the characteristics of the disease, it is likely that a more definite treatment can be advised. =Malarial Fever.=—_Synonyms._—Ague; Chills and fever; Intermittent fever; Swamp fever; Marsh fever; Paludal fever. _Definition._—A specific, infectious, although non-contagious disease, caused by the hematozoa of Lavaran, and consisting of two distinct parts; first, a succession of exacerbations and intermissions, or a series of short fevers separated by short intervals of health; second, a continued fever made up of exacerbations and remissions, there being but one cold stage. _Cause._—The hematozoa of Lavaran. _Pathology._—There is a destruction of the red blood corpuscles, due to the action of the parasite. There is an increase of pigment, in the spleen, liver, kidneys, bone marrow, skin, and in fact, in all the tissues, due to the conversion of hemoglobin into pigment granules. The spleen is enlarged as are also the liver and the kidneys. The skin presents a jaundiced appearance in chronic malarial fever. _Treatment._—Arterial injection of 64 oz. 1% solution of borax or oxalic acid followed by 64 oz. of half strength fluid and then a sufficient quantity of normal fluid to complete preservation. Drainage of blood and solution to wash stain from capillaries. Application of full strength peroxide hydrogen to face, and massage during injection.
