Cornet even declares that " we daily are able to see that even the most robust people, apparently in the best of health, become the victims of the tubercle-bacilli infection." Summarizing the observations made in two hundred and twenty-one autopsies of tuberculous cases, Grawitz, formerly Virchow's assistant, reported one hundred and fifty-two cases as primary in the lungs, nine as primary in the digestive tract, three arising from external wounds, and the original entrance of the infection was doubtful in the other cases. {Deutsch. militdriirzU. Zeitschr., 1889, Heft 10, Ref.) Then some of the many cases where animals were experimentally fed with tuberculous meat and milk resulted in Voltaren Xr 100 intestinal infection. But such facts had Voltaren Xr 100 Mg been observed years before the charac- teristic bacilli were recognized. Leudet (Gaz. fiebdom., 1890, No. 9), reviewing many cases among married people in the better circles of society, states (like Brehmer and many others) that it is exceedingly rare for tubercular in- fection to pass from one spouse to the other. Schwarz and numerous others adduce the facts of long and extensive hospital experiences to show that hospital attendants are not so prone to the affection as Cornet assumed, and Haupt (Med. Revue, 1890, No. 1), gathering the statistics of two hundred and seventy-five female nurses encountering tuber- culosis in a general experience, found that during twelve years only two of these nurses had manifested the symp- toms of the disease. In this country, comprehensive inves- tigations of nursing statistics made with similar care are not at hand. We, who have seen many cases in the homes of the poor before any care was paid to adequate disinfec- tion, can not, so far as I learn, recall much evidence of the disease being communicated from one to another of those living in the unhealthy abodes of our lowest classes. But, aside from the lack of positive evidence to prove the extremist views, there are further facts to negative or modify the postulates. Thus Prausnitz [Archivf. Hygiene, 1891, p. 192) reports negative results when inoculating ani- mals with dust taken from the floor of railway compart- ments in through trains carrying consumptives for many hours on the long journey through Bavaria. Kustermann {Munch, med. Woch., Nov. 10, 1891, p. 796) reports wholly negative results from collecting dust from the walls and floors of the Munich prison hospital, and then inoculating this dust into animals. Happily the element of contagion, even if existing on the clothes, the skin, and in all the secretions, soon loses its vitality under the conditions most prevalent. Koch has said that when exposed to da3'light and the oxygen of the air, the tubercle bacilli present in dust form are liable to die in from a few hours to a few days. Although the temptation is ever present to use a " royal road " for learning about the origin of the disease and, by assuming the inhalation theory Buy Voltaren Xr as explaining all cases, to consider other explanations as unwarranted, it must be in- sisted that the inhalation theory accounts for only a portion of the cases, and that, after all, heredity seems a very potent source, as evidenced by the common-sense experience of clinicians and statistical observers, as well as by bacteriolo- gists of the highest standing, such as Professor Baum- garten (see Deutsche med. Wochenachrift, Oct. 13, 1891) and others, who are Voltaren Xr 100mg thoroughly conversant with the exten- sive literature of the subject and acquainted with all the progress and changes of the decade. An infant seems quite as liable to inhale the bacteria of exsiccated sputum as an adult is, and then to develop tuberculosis of the lungs if the inhalation theory is adequate to account for all cases ; but we have the clinical fact presented us that the lungs do not develop tuberculosis in infants as often as in adult life, yet the glands, bones, and joints are relatively very often affected without any evidence that the infection arose pri- marily in the subject through inhalation of bacteria. These considerations, together with the occurrence of cases of fcetal tuberculosis (Birch-Hirschfeld and Rindfleisch, Mitii- Related links: Generic Ddavp, How Much Does Azithromycin Liquid Cost, zithromax overnight, cheap spiriva, kamagra gel oral 100 mg, Zovirax Order Online, buy accutane for acne, Duricef Antibiotic, Can You Buy Accutane Online, Kamagra 100mg Jelly
