Willett relates the instance of a horseman of thirty-three who, after using a combination of refuse oils to protect his horse from gnats, was prompted to urinate, and, in so doing, accidentally touched his penis with the mixture. Sloughing phagedena rapidly ensued, but under medical treatment he eventually recovered.

Priapism is sometimes seen as a curious symptom of lesion of the spinal cord. In such cases it is totally unconnected with any voluptuous sensation and is only found accompanied by motor paralysis. It may occur spontaneously immediately after accident involving the cord, and is then probably due to undue excitement of the portion of the cord below the lesion, which is deprived of the regulating influence of the brain. Priapism may also develop spontaneously at a later period, and is then due to central irritation from extravasation into the substance of the cord, or to some reflex cause. It may also occur from simple concussion, as shown by a case reported by Le Gros Clark. Pressure on the cerebellum is supposed to account for cases of priapism observed in executions and suicides by hanging. There is an instance recorded of an Italian "castrate" who said he provoked sexual pleasure by partially hanging himself. He accidentally ended his life in pursuance of this peculiar habit. The facts were elicited by testimony at the inquest.

There are, however, in literature, records of long continued priapism in which either the cause is due to excessive stimulation of the sexual center or in which the cause is obscure or unknown. There may or may not be accompanying voluptuous feelings. The older records contain instances of continued infantile priapism caused by the constant irritation of ascarides and also records of prolonged priapism associated with intense agony and spasmodic cramps. Zacutus Lusitanus speaks of a Viceroy of India who had a long attack of stubborn priapism without any voluptuous feeling. Gross refers to prolonged priapism, and remarks that the majority of cases seem to be due to excessive coitus.

Moore reports a case in a man of forty who had been married fifteen years, and who suffered spasmodic contractions of the muscles of the penis after an incomplete coitus. This pseudopriapism continued for twenty-three days, during which time he had unsuccessfully resorted to the application of cold, bleeding, and other treatment; but on the twenty-sixth day, after the use of bladders filled with cold water, there was a discharge from the urethra of a glairy mucus, similar in nature to that in seminal debility. There was then complete relaxation of the organ. During all this time the man slept very little, only occasionally dozing. Donne describes an athletic laborer of twenty-five who received a wound from a rifle-ball penetrating the cranial parietes immediately in the posterior superior angle of the parietal bone, and a few lines from the lambdoid suture. The ball did not make egress, but passed posteriorly downward. Reaction was established on the third day, but the inflammatory symptoms influenced the genitalia. Priapism began on the fifth day, at which time the patient became affected with a salacious appetite, and was rational upon every subject except that pertaining to venery. He grew worse on the sixth day, and his medical adviser was obliged to prohibit a female attendant. Priapism continued, but the man went into a soporose condition, with occasional intervals of satyriasis. In this condition he survived nine days; there was not the slightest abatement of the priapism until a few moments before his death. Tripe relates the history of a seaman of twenty-five, in perfect health, who, arriving from Calcutta on April 12, 1884, lodged with a female until the 26th. At this time he experienced an unusually fierce desire, with intense erection of the penis which, with pain, lasted throughout the night. Though coitus was frequently resorted to, these symptoms continued. He sought aid at the London Hospital, but the priapism was persistent, and when he left, on May 10th, the penis formed an acute angle with the pubes, and he again had free intercourse with the same female. At the time of leaving England the penis made an angle of about 45 degrees with the pubes, and this condition, he affirmed, lasted three months. On his return to England his penis was flaccid, and his symptoms had disappeared.

Salzer presents an interesting paper on priapism which was quoted in The Practitioner of London. Salzer describes one patient of forty-six who awoke one morning with a strong erection that could not be reduced by any means. Urine was voided by jerks and with difficulty, and only when the subject was placed in the knee and elbow position. Despite all treatment this condition continued for seven weeks. At this time the patient's spleen was noticed to be enormously enlarged. The man died about a year after the attack, but a necropsy was unfortunately refused. Salzer, in discussing the theories of priapism, mentions eight cases previously reported, and concludes, that such cases are attributable to leukemia. Kremine believes that continued priapism is produced by effusion of blood into the corpora cavernosa, which is impeded on its return. He thinks it corresponds to bleeding at the nose and rectum, which often occurs in perfectly healthy persons. Longuet regards the condition of the blood in leukemia as the cause of such priapism, and considers that the circulation of the blood is retarded in the smaller vessels, while, owing to the great increase in the number of white corpuscles, thrombi are formed. Neidhart and Matthias conclude that the origin of this condition might be sought for in the disturbance of the nerve-centers. After reviewing all these theories, Salzer states that in his case the patient was previously healthy and never had suffered the slightest hemorrhage in any part, and he therefore rejects the theory of extravasation. He is inclined to suppose that the priapism was due to the stimulation of the nervi erigentes, brought about either by anatomic change in the nerves themselves, or by pressure upon them by enlarged lumbar glands, an associate condition of leukemia.

Burchard reports a most interesting case of prolonged priapism in an English gentleman of fifty-three. When he was called to see the man on July 15th he found him suffering with intense pain in the penis, and in a state of extreme exhaustion after an erection which had lasted five hours uninterruptedly, during the whole of which time the organ was in a state of violent and continuous spasm. The paroxysm was controlled by 3/4 grain morphin and 1/50 grain atropin. Five hours later, after a troubled sleep, there was another erection, which was again relieved by hypodermic medication. During the day he had two other paroxysms, one lasting forty-five minutes; and another, three hours later, lasting eighteen minutes. Both these were controlled by morphin. There was no loss of semen, but after the paroxysms a small quantity of glairy mucus escaped from the meatus. The rigidity was remarkable, simulating the spasms of tetanus. No language could adequately describe the suffering of the patient. Burchard elicited the history that the man had suffered from nocturnal emissions and erotic dreams of the most lascivious nature, sometimes having three in one night. During the day he would have eight or ten erections, unaccompanied by any voluptuous emotions. In these there would rarely be any emission, but occasionally a small mucous discharge. This state of affairs had continued three years up to the time Burchard saw him, and, chagrined by pain and his malady, the patient had become despondent. After a course of careful treatment, in which diet, sponging, application of ice-bags, and ergot were features, this unfortunate man recovered.

Bruce mentions the case of an Irishman of fifty-five who, without apparent cause, was affected with a painful priapism which lasted six weeks, and did not subside even under chloroform. Booth mentions a case of priapism in a married seaman of fifty-five, due to local inflammation about the muscles, constricting the bulb of the penis. The affection lasted five weeks, and was extremely painful. There was a similar case of priapism which lasted for three weeks, and was associated with hydrocele in a man of forty-eight.

Injuries of the testicle and scrotum may be productive of most serious issue. It is a well-known surgical fact that a major degree of shock accompanies a contusion of this portion of the body. In fact, Chevers states that the sensitiveness of the testicles is so well known in India, that there are cases on record in which premeditated murder has been effected by Cossiah women, by violently squeezing the testicles of their husbands. He also mentions another case in which, in frustrating an attempt at rape, death was caused in a similar manner. Stalkartt describes the case of a young man who, after drinking to excess with his paramour, was either unable, or indifferent in gratifying her sexual desire. The woman became so enraged that she seized the scrotum and wrenched it from its attachments, exposing the testicles. The left testicle was completely denuded, and was hanging by the vas deferens and the spermatic vessels. There was little hemorrhage, and the wound was healed by granulation.

Avulsion of the male external genitalia is not always accompanied by serious consequences, and even in some cases the sexual power is preserved. Knoll described a case in 1781, occurring in a peasant of thirty-six who fell from a horse under the wheels of a carriage. He was first caught in the revolving wheels by his apron, which drew him up until his breeches were entangled, and finally his genitals were torn off. Not feeling much pain at the time, he mounted his horse and went to his house. On examination it was found that the injury was accompanied with considerable hemorrhage. The wound extended from the superior part of the pubes almost to the anus; the canal of the urethra was torn away, and the penis up to the neck of the bladder. There was no vestige of either the right scrotum or testicle. The left testicle was hanging by its cord, enveloped in its tunica vaginalis. The cord was swollen and resembled a penis stripped of its integument. The prostate was considerably contused. After two months of suffering the patient recovered, being able to evacuate his urine through a fistulous opening that had formed. In ten weeks cicatrization was perfect. In his "Memoirs of the Campaign of 1811," Larrey describes a soldier who, while standing with his legs apart, was struck from behind by a bullet. The margin of the sphincter and, the skin of the perineum, the bulbous portion of the urethra, some of the skin of the scrotum, and the right testicle were destroyed. The spermatic cord was divided close to the skin, and the skin of the penis and prepuce was torn. The soldier was left as dead on the field, but after four months' treatment he recovered.

Madden mentions a man of fifty who fell under the feet of a pair of horses, and suffered avulsion of the testicles through the scrotum. The organs were mangled, the spermatic cord was torn and hung over the anus, and the penis was lacerated from the frenum down. The man lost his testicles, but otherwise completely recovered. Brugh reports an instance of injury to the genitalia in a boy of eighteen who was caught in a threshing-machine. The skin of the penis and scrotum, and the tissue from the pubes and inguinal region were torn from the body. Cicatrization and recovery were complete. Brigham cites an analogous case in a youth of seventeen who was similarly caught in threshing machinery. The skin of the penis and the scrotum was entirely torn away; both sphincters of the anus were lacerated, and the perineum was divested of its skin for a space 2 1/2 inches wide. Recovery ensued, leaving a penis which measured, when flaccid, three inches long and 1 1/2 inches in diameter.
