Produktbeschreibung
Excerpt from A Treatise Tubercular Phthisis: Or, Pulmonary Consumption Tubercular Phthisis, or Consumption, Phthisis Tuberculosa, Phthisis Pulmonalis. It was first used as a generic term to signfiy consumption of every kind, and was afterwards more distinctly specified according to the organ in which it was supposed to originate, as phthisis pulmonalis, phthisis hepatica, phthisis mesentenca, &c.; indeed it has even been applied to the wasting attendant on various diseases, as phthisis rheumatica, phthisis syphilitica, phthisis scorbutica, and many others. These indiscriminate appropriations of the term gave rise to much vagueness and confusion in its practical application. But as the knowledge of morbid anatomy became more precise, disease of the lungs was found to be most frequently connected with consumption; and hence phthisis pulmonalis not only attracted far greater attention than any other form of the disease, but a large proportion of the other species were found to resolve themselves into this, having been discovered to be mere complications of it. Phthisis pulmonalis was now divided into various species, according to the real or imaginary nature of the pulmonary disease upon which the symptoms were supposed to depend. At length, Laennec, finding, in the course of his extensive researches into pulmonary diseases, that tubercles formed almost the universal cause of consumption, proposed to restrict the term phthisis to the disease produced by tubercles in the lungs; and since the publication of his great work in 1819, (an important era in our knowledge of pulmonary diseases,) the term has been so restricted in France. The accuracy of Laennec´s opinions has been confirmed by the subsequent investigations of Louis and Andral, whose minute and laborious researches have given a precision to our knowledge of the subject which was unknown before their time. But, notwithstanding the advantages which have resulted from the adoption of these views, they have tended to keep alive the idea that pulmonary phthisis is a local disease, referrible to a local cause: and thus the constitutional origin of tubercles, by far the most important part of the subject, has been neglected. Before we can hope to acquire an accurate knowledge of consumption, we must carry our researches beyond those morbid alterations which constitute the pulmonary disease and are only a secondary affection, - the consequences of a pre-existing constitutional disorder, which is the necessary condition that determines the production of tubercles. An imperfect acquaintance with the nature of tubercles and with the morbid state of the system in which they have their origin, has led to great discrepancy of opinion concerning the nature and causes of phthisis pulmonalis. There are many, even at the present day, who regard tuberculous disease of the lungs as the result of inflammation; an opinion which we consider as not only erroneous, but as having been productive of a very mischievous practice. Inflammation of the respiratory organs may, and we believe often does give rise to tubercles, and unquestionably accelerates their progress; but we also believe inflammation to be incapable of producing tubercles in a healthy constitution. Chronic inflammation of the different tissues of which the lungs are composed, is often accompanied with symptoms closely resembling those produced by tuberculous disease. Chronic bronchitis and chronic pleurisy afford examples of this kind; and the distinction between these and tuberculous disease of the lungs, becomes, in some cases, very difficult. Hence they have been, and still are often confounded, and considered, as regards each other, in the light of cause and effect.
