Characteristics
A paralytic affection named *Lathyrism has been recognized from ancient times, and has been commonly attributed, as its name implies, to poisoning with *Lathyrus, a species of pea. Our own Sweet Pea is *Lathyrus odoratus. The two varieties of *Lathyrus which have occasioned the poisonings are *Lath. sativus and *Lath. cicera. The peas are very much alike in appearance. That of *Lath. Cicera is rather smaller than the other, more square, are a lighter brown. Except for this brownish colour they could easily be mistaken for ordinary peas. *Lath. Cicera has red flowers, *Lath. Sativus bluish. Both are cultivated for food, and are sometimes cut green for fodder. Accidents have most commonly happened in famine seasons, and the best account of such a poisoning is communicated by C. Bojanus to *Fourn. *of B.H.S., July, 1897. But it is not only in such cases that poisoning has occurred. Two cases are recorded (*H. W., xix. 319) as having been admitted to the University clinic of Parma. The patients were two brothers aged seventeen and twelve, of excellent personal and family history, and in good bodily health. They were admitted as suffering from locomotor ataxy and chronic myelitis. For a year past they had eaten bread made with the flour of *Lath. sat. And *Lath. Cicuta The elder had at times eaten the vetches green. This caused nausea, vomiting, giddiness, singing in the ears, stupidity. These symptoms gradually increased, then tremor of upper extremities appeared, worse when taking up or putting down anything. Legs heavy with vague pains, formication and sense of cold. He was unable to stand without the help of a stick. There was no weakness, but the abductors and flexors of the lower limbs felt hard and contracted. Gait uncertain and staggering, right leg being rather the stronger. He lifted his feet with difficulty, often dragged them and put them down suddenly and forcibly, as if they were heavy weights. The floor, he said, felt irregular, and he was obliged to keep his eyes fixed on the ground to guide his feet. He rested all his weight on a stick. Movement worse when eyes shut, he “felt as if standing between two abysses.” He walked worse without his shoes. In bed he could not sit up without helping himself up with his arms. He could not move his toes or flex or extend the foot on the leg, or the leg on the thigh, could not extend or close legs when sitting, voluntary movement of abductor and adductors, and rotation of feet impossible. Knee-jerk exaggerated. Sensibility to touch, heat, pain, and electricity perfect. Temperature normal. The *Brit. F. of. H. (xlii. 81) quoted from *L’Art Medical of August, 1882, an article on Lathyrism as observed in Algiers from the effects of eating bread made with wheat and barley flour mixed with flour of the seeds of *Lath. Cicuta When the wheat harvest is bad *Lath. Cicuta Is used by the poorer inhabitants in as high a proportion as three parts to one of the other two. The resulting disease is perfectly well known to the Algerians, who call it, form the Arabic name of the plant, *jilben. These are the symptoms: (I) Lumbago, incontinence if urine, complete loss of sexual power, pains in lower and sometimes upper limbs, tremors. The invasion of the disease is sudden, often coming on *after a damp, *cold night. (2) The lower limbs are affected with anesthesia and motor paralysis. After the lapse of some days or weeks the patients can rise up, and they show a characteristic gait, the heel in the air, foot in extension and abduction, with contraction of muscles of lower limbs and exaggerated reflexes. At this period few show any disturbances of sensibility, and there are no longer any affections of bladder and genitals. In the case related by Bojanus the general symptoms were the same. In these it was the *Lath. sat. which was the cause of the trouble, which arose during the great Russian famine. A few symptoms may be mentioned. Case i., Man. 21. after eating *Lath. sat. for three months had the usual paralytic symptoms, and “strong pressure on bladder with frequent desire to micturate.” “When sitting had great swelling of legs.” “predominating coldness in legs, which at night changes to a hot, burning sensation, with desire to uncover.” Respiration, heart, and digestion normal. Case iii., man, 25, felt (I) heaviness and pains in region of stomach. heartburn, nausea, sometimes vomiting (once of blood), colics, sometimes diarrhoea, followed by general weakness, tremor, difficulty in moving, coldness of feet, and cramps in calves. (2) About a week later, pressure on bladder so violent that he had to urinate immediately or the urine rushed out of its own accord with great force. The diarrhoea increased, and was accompanied by pressure on the intestines similar to that on the bladder. Sexual excitability lost, pains in back. In hospital the bladder and intestinal symptoms passed off, but the paralysis remained. Cramps in calves, legs blue and cold, morning and night hot and burning. This recurs regularly every day and lasts a few hours. Pains in back excited by tough and efforts to rise. Case iv., man, 32, had (I) heartburn, sickness, vomiting, vomiting of blood, dysentery. (2) Cramps in calves, pains in back so violent that he could hardly move, depressed, hypochondriacal. Hardly any movement possible in coxofemoral joint. From time to time erections and pollutions. Horses fed with *Lath. along with oats manifested symptoms of paralysis of the limbs, and also of the throat and wind-pipe, setting up the condition called “Roaring.” Some have died of suffocation. The worse from cold, damp wind appears to be the leading Condition of *Lath. so far as at present known. In the case of horses as well as of human beings, the symptoms often remain in abeyance until cold, damp weather sets in. Burning heat with better by uncovering is another noteworthy condition. Provings, especially provings with potencies, are required to being out the fine indications. When these are available *Lath. will doubtless prove a notable remedy in spinal complaints. As it is the likeness to many forms of spastic paralysis, to Beriberi, and to cases of locomotor ataxy, is sufficiently close to warrant its use. I have relieved with it several cases of spastic paralysis, Miss R., 25, had been ill four years with the usual symptoms of spastic paralysis, with excessive constipation and violent urging to pass water, if she attempted to retain it, it passed of itself. The muscles were hard and unyielding. She had very heavy drugging under allopathic treatment before coming under my care. *Hypericum was first given with considerable benefit. As the improvement went no further, *Lath. Sat. I and 30 were given, and then the improvement was much more marked. The patient is still under treatment. In one of the cases of lathyrism the back pain was induced by touch. Worse by touch may prove a keynote, as worse in damp, cold weather certainly ought to. Better Uncovering was prominent in several cases. Worse By movement. Better Lying down (lower limbs move freely. I have not seen any observation recorded in female sufferers, and men are more sensitive to it than women. It should be like *Nux-v., a man’s medicine. It affects chiefly the parts below the waist. Lumbago with bladder affections should be curable by it. W.A. Dewey (*Medorrhinum Cent., viii. 17) has recorded a brilliant cure with *Lath. sat. 3x of a case of spastic paralysis in a man of twenty-eight. The attack had been coming on six months. The patient was a hunchback, having been deformed since the age of five, but this had given no more than the usual inconvenience. On admission to hospital (December I. 1898) he was unable to make the slightest movement of the lower extremities, even of the toes. The adductors were in a constant state of irritable contraction, so that the thighs were constantly crossed. Reflexes greatly exaggerated. No pain. Spine not tender. General health normal. The only other symptoms was a girdle sensation, as if he had a cloth wrung out of cold water round his waist. Three weeks after commencing *Lath. sat. there was slight lessening of rigidity. On April 5, 1899, he could raise his limbs and move his toes. On July 2nd he walked out of the hospital without difficulty, the abnormal irritability of the muscles having disappeared. In 1877 (I think) I published cases relieved by *Lath. sat., two of Paralysis, one of multiple sclerosis, one of rheumatic paralysis with stiff knees.
