SYPHILIS OF THE STOMACH.—THE FILTERABLE VIRUSES.
neglected the skin of the animal has a peculiar mousy odour and becomes very loathsome. In human beings the individual lesion is a very small and thin-walled vesicle, slightly smaller than the ordinary eczema vesicle, and surrounded by a narrow zone of bypersemia, very like that of varicella, but only about one-eighth the size. These lesions are always scattered discretely over the surface and not in grouped ’, lesions. The intense irritation leads to the decapitation of the little vesicles, and their original site becomes covered with either a serous or blood scab. No burrows are found, and thus it is very difficult to discover the actual parasite. This latter fact makes it necessary to trace up the source of origin, if possible, to an "itchy"dog, and in one of the instances alluded to in the article the patient was re-infected three times before it occurred to the medical man to investigate the socalled "eczema"of his patient’s dog. The course of the disease in the human being is about six weeks, in the absence of treatment and of re-infection ; and, if treated, the ordinary treatment for human scabies is quite efficient, the disease showing less tendency to relapse because the parasite doe" not burrow. In the dog and cat the average duration of treatment to effect a cure is about three or four weeks ; and here again, unless a re-infection occurs, the cure is permanent.
cases gastric symptoms occurred as early as two years after infection, in 2 cases after four years, and in 2 cases after
five years. The majority of cases occurred in the tertiary period. In the congenital cases there was a multiplicity of lesions-gummata of the liver, intestines, bones, or lungs. Such multiplicity was present in only a minority of the acquired cases. The gastric lesions were various-gumma, The gummata occurred in all ulcer, and peritonitis. parts of the stomach, and varied in size from microscopic lesions to ones of the size of the hand. In some cases they were circumscribed, in others widespread. When near the pylorus they produced the symptoms of stenosis due to a neoplasm. Sometimes they ulcerated deeply and even led to perforation. Large parts of the stomach were sometimes involved, giving rise to such diagnoses as linitis, chronic hypertrophic gastritis, and pyloric stenosis. Hmmorrhage may result from erosion of a blood-vessel. Finally, in con-
sequence of massive infiltration or adhesions hour-glass contraction of the stomach may be produced. Thus, syphilis of the stomach presents the protean character of the disease in other parts. It is often mistaken for other gastric diseases. Probably it is more common than is supposed, and some of the intractable cases of so-called simple ulcer or gastric tumour, if more closely scrutinised, would turn out to be syphilitic. Suspicion should be aroused by a history of syphilis or the presence of the Wassermann reaction. SYPHILIS OF THE STOMACH.
