Syphilis from a Flea-bite.--Jonathan Hutchinson, in the October, 1895, number of his unique and valuable Archives of Surgery, reports a primary lesion of most unusual origin. An elderly member of the profession presented himself entirely covered with an evident syphilitic eruption, which rapidly disappeared under the use of mercury. The only interest about the case was the question as to how the disease had been acquired. The doctor was evidently anxious to give all the information in his power, but was positive that he had never been exposed to any sexual risk, and as he had retired from practice, no possibility of infection in that manner existed. He willingly stripped, and a careful examination of his entire body surface revealed no trace of lesion whatever on the genitals, or at any point, except a dusky spot on one leg, which looked like the remains of a boil. This, the doctor stated, had been due to a small sore, the dates of the appearance and duration of which were found to fit exactly with those of a primary lesion. There had also been some enlargement of the femoral glands. He had never thought of the sore in this connection, but remembered most distinctly that it followed a flea-bite in an omnibus, and had been caused, as he supposed, by his scratching the place, though he could not understand why it lasted so long. Mr. Hutchinson concludes that all the evidence tends to show that the disease had probably been communicated from the blood of an infected person through the bite of the insect. It thus appears that even the proverbially trivial fleabite may at times prove a serious injury.
Snake-bites.--A writer in an Indian paper asserts that the traditional immunity of Indian snake-charmers is due to the fact that having been accidentally bitten by poisonous serpents or insects more than once, and having survived the first attack, they are subsequently immune. His assertion is based on personal acquaintance with Madari Yogis and Fakirs, and an actual experiment made with a Mohammedan Fakir who was immune to the bites of scorpions provided by the writer. The animals were from five to seven inches long and had lobster-like claws. Each bite drew blood, but the Fakir was none the worse.
The venom of poisonous snakes may be considered the most typical of animal poisons, being unrivaled in the fatality and rapidity of its action. Fortunately in our country there are few snake-bites, but in the tropic countries, particularly India, the mortality from this cause is frightful. Not only are there numerous serpents in that country, but the natives are lightly dressed and unshod, thus being exposed to the bites of the reptiles. It is estimated by capable authorities that the deaths in India each year from snake-bites exceed 20,000. It is stated that there were 2893 human beings killed by tigers, leopards, hyenas, and panthers in India during the year 1894, and in the same year the same species of beasts, aided by snakes, killed 97,371 head of cattle. The number of human lives destroyed by snakes in India in 1894 was 21,538. The number of wild beasts killed in the same year was 13,447, and the number of snakes killed was 102,210.
Yarrow of Washington, who has been a close student of this subject, has found in this country no less than 27 species of poisonous snakes, belonging to four genera. The first genus is the Crotalus, or rattlesnake proper; the second is the Caudisona, or ground-rattlesnake; the third is the Ancistrodon, or moccasin, one of the species of which is a water-snake; and the fourth is the Elaps, or harlequin snake. There is some dispute over the exact degree of the toxic qualities of the venom of the Heloderma suspectum, or Gila monster. In India the cobra is the most deadly snake. It grows to the length of 5 1/2 feet, and is most active at night. The Ophiophagus, or hooded cobra, is one of the largest of venomous snakes, sometimes attaining a length of 15 feet; it is both powerful, active, and aggressive. The common snakes of the deadly variety in the United States are the rattlesnake, the "copperhead," and the moccasin; and it is from the bites of one of these varieties that the great majority of reported deaths are caused. But in looking over medical literature one is struck with the scarcity of reports of fatal snake-bites. This is most likely attributable to the fact that, except a few army-surgeons, physicians rarely see the cases. The natural abode of the serpents is in the wild and uninhabited regions.
The venom is delivered to the victim through the medium of a long fang which is connected with a gland in which the poison is stored. The supply may be readily exhausted; for a time the bite would then be harmless. Contrary to the general impression, snake-venom when swallowed is a deadly poison, as proved by the experiments of Fayrer, Mitchell, and Reichert. Death is most likely caused by paralysis of the vital centers through the circulation. In this country the wounds invariably are on the extremities, while in India the cobra sometimes strikes on the shoulder or neck.
If called on to describe accurately the symptoms of snake-venom poisoning, few medical men could respond correctly. In most cases the wound is painful, sometimes exaggerated by the mental condition, which is wrought up to a pitch rarely seen in other equally fatal injuries. It is often difficult to discern the exact point of puncture, so minute is it. There is swelling due to effusion of blood, active inflammation, and increasing pain.
