B. F. Dawson,11 after reciting a case in which the liver had undergone a peculiar degeneration and was attended by peritonitis before birth, states that Sir J. Y. Simpson observed nine cases in his own practice "and notes more than a dozen from different sources." These cases seemed to have been caused by the ill-health of the mother during gestation, or excessive labor, injuries, venereal disease, and were mostly attended by grave disease; the viscera often, the liver; but sometimes the mother was perfectly healthy, and the peritonitis was the primary disease. Death almost always occurred in utero or shortly after birth. In one instance the child recovered.

11 N.Y. Med. Journ., Dec., 1882.

The Med. Record takes the following from Schmidt's Jahrbucher for Jan. 7, 1883: "Dr. Oscar Silbermann recognizes two varieties of peritonitis in the new-born. The non-septic or chronic is developed usually in the first third of foetal life, and is generally syphilitic in origin. If the peritoneum covering the intestines be involved, as well as that over the liver and spleen, various forms of intestinal obstruction may result. Most frequently there is occlusion of the anus, less often stenosis or complete stricture of the small intestine. Of a number of cases of congenital occlusion of the intestine collected by the author, all ended fatally, only one living beyond twelve days.

"The second, acute or septic, form of peritonitis in the new-born the author divides into two varieties, according as the peritonitis is only a part of general infection or is the sole manifestation of the septic poison. In either case the point of entrance of the poison is always the navel wound. The symptoms, which need not all be present in a given case, are vomiting, watery stools, meteorism, ascites, abdominal tenderness, icterus, etc. The pulse and temperature may vary in degree in different cases. A cure of the septic form is possible; therefore the treatment should be carefully considered. The navel wound should be cleansed, and the child is to be isolated from its mother. To control the fever quinine may be given. Priessnitz's sheet is of value; vomiting may be checked by chloral (one-half to one grain in water). The strength should of course be maintained by stimulants if necessary."

Ascites.

The accumulation of fluid indicated by this name has already been referred to in its relations to several causes. There are, however, conditions producing it which have not been considered or only considered partially.

The most prolific source of abdominal dropsy is obstruction of the portal circulation on its way to or through the liver. Condensation of the liver structure in cirrhosis, with destruction of many of the portal capillaries and compression of many more, is prominent in this connection. The compression of the liver caused by an adventitious external covering, referred to under the head of Local Peritonitis, acts similarly, whether it compresses the vein at its entrance into the liver or not, although it is not known to produce any destruction of the portal capillaries. Some enlargements of the organ are attended by the same result, but they are always associated with a hardening of its structure. The disease lately called waxy liver, now often denominated lardaceous, belongs to this class, as does that condition in which the organ is enlarged, hardened, and fissured, regarded as syphilitic liver. That both these diseases may have a syphilitic and mercurial origin is not a point now under consideration. They both harden the hepatic structure and obstruct the portal circulation, while they may not in equal degree hinder the progress of arterial blood. This is explained when we remember the diminished force that propels the portal blood. Neither of these diseases produces dropsy early in its progress, but, as I have seen it, always before it reaches its fatal termination. Fatty liver has not, in my observation, produced dropsy, although I have seen livers made very large by that disease, and the absence of dropsy when the liver has been large has aided me in distinguishing it from the waxy disease. Cancer of the liver in some instances does, and in others does not, produce dropsy of the bowels. It is only certain to have this result when a tumor is in position to press upon and obstruct the portal. Hypertrophy of the liver, caused by mitral regurgitation or other disease of the heart, does not generally produce dropsy, but, aided by anæmia or watery condition of the blood, such a result is possible. In children, however, it is not very rare to see the bowels distended by dropsy, and to discover that the liver is enlarged at the same time. It is common in such cases that the dropsy and the hypertrophy disappear after a few weeks of treatment. This may occur in a child that is anæmic, but without any disease of the heart. Such a case was brought to me two or three months ago, and after four weeks of treatment by tonics and diuretics the health was re-established. There is one point in these cases of some importance. When the child lies on his back, if the abdomen is much distended, the liver cannot be felt. It has sunk away into the fluid, and in this position ordinary percussion cannot ascertain its dimensions. In the July number (1840) of a quarterly journal edited by Swett and Watson, I published an article in which I reported the conjoined labors of the late Camman and myself on a new method of combining auscultation and percussion, with its results, under the heading "Auscultatory Percussion." By the method described in that article—viz. by placing a solid stethoscope, or for that Laennec's first stethoscope, a rolled-up pamphlet, on the chest at a point where the liver has not fallen away from its walls, and percussing on the abdomen from below upward—a point is reached whence the percussion sound is brought sharply to the ear, while half an inch below the sound is dull and distant. The lower edge of the liver is thus easily recognized, and its upper boundary is found in a similar manner or by ordinary percussion, so the difficulty of measurement disappears.

In such case, when the dropsy disappears and the liver recovers its natural dimensions at the same time, the inference is that the hypertrophy caused the dropsy, and that the hypertrophy was of the kind called simple. The nutmeg liver is thought to have an agency in producing dropsy, but as it is for the most part associated with diseases that have been called dropsy-producing, its bearing on this effusion may yet be regarded as uncertain.

It is common to speak of heart dropsy in such a way as to imply that disease of the heart alone can produce abdominal effusion. I doubt it. I even doubt whether the heart alone can cause the anasarca that is so often attributed to it. In following a great multitude of heart diseases from the time they were recognized to their termination, I have been struck with the ease with which the patients attend to their business, sometimes even laborious business, for years—in one instance fifty years—with almost no complaint, and how rapidly their condition changes as soon as albumen and casts appear in the urine. I have been compelled by these observations to ascribe the anasarca and oedema that makes this last stage of heart disease so distressing to the kidneys, and not to the heart. Double pleuritic effusion is not uncommon under these circumstances, but every physician must have noticed the rareness of troublesome abdominal dropsy, while there is sometimes—perhaps often—a little effusion; and when in the exceptional cases there has been much, it was almost always accounted for by a dropsy-producing change in the abdominal organs, not, perhaps, discovered during life; so that for me, while they produce overwhelming effusions in other parts of the system, they are minor agents in the production of ascites. Phthisis is occasionally attended, toward its close, by oedematous legs and albuminous urine, but I cannot report any important relation between these and peritoneal effusion. I can say the same of chronic bronchitis. I record this negative testimony regarding the two last-named diseases, because I find them enumerated among the causes of abdominal dropsy.

Cancer may invade the portal vein, tumors of adjacent parts other than those of the liver, or an aneurism may compress it and cause dropsy. Hydatid tumors may do this. Diseases of the pelvic organs, both acute and chronic, may produce it, but then the disease would fall into the class of those produced by chronic or subacute peritonitis.
