e back. The disease is essentially a chronic one, 

 but the patient becomes absolutely helpless long 

 before death. It is most common in young male 

 children usually under ten years of age. The disease 

 is entirely myopathic, no adequate nerve-lesion hav- 

 ing as yet been discovered. P., Puerperal, the 

 paralysis following labor. It may be due to trauma- 

 tism during deliver) - , to pressure by the uterus, or 

 from displacement of the pelvic organs, to puerperal 

 sepsis, to phlebitis and phlegmasia alba dolens (these 

 are really septic causes). These causes usually induce 

 inflammation of the lumbar and sacral nerves. There 

 may, however, be myelitis from puerperal septic in- 

 fection. P., Rachitic Pseudo-, the motor weak- 

 ness observed in the lower limbs of marked cases of 

 rickets. There is no true paralysis, the condition being 

 due to changes in the ligaments, softening of the 

 bones, and weakness of the muscles. P., Radial. 

 Synonym of P., Musculo- spiral. P., Reflex, the 

 paralysis which sometimes follows immediately upon 

 a wound of a nerve, or the paraplegia that is some- 

 times due to irritation of an adherent prepuce. Other 

 so-called reflex palsies, as that from renal calculus, are 

 probably due to secondary changes in the spinal cord 

 or nerves. P., Regressive. See P., Infantile. P., 

 Rheumatic, a paralysis from peripheral neuritis the 

 cause of which is apparently exposure to cold, e. g. , in 

 some cases of facial paralysis. P., Saturnine. Syno- 

 nym of P., Lead. P., Scrivener's. Synonym of 

 Cramp. Writers'. P., Segmental, a paralysis of" a seg- 

 ment of a limb produced by hypnotism. P., Sensory, 

 anesthesia. P., Sleep, paralysis of the musculo-spiral 

 nerve from pressure upon it during sleep. P., Spastic, 

 a paralysis associated with rigidity of the muscles and 

 heightened tendon-reflexes. P., Spastic Spinal. 

 Synonym of Lateral Sclerosis. P., Telegraphers', 

 an anapeiratic paralysis sometimes seen in telegraph- 

 operators. P., Toxemic, one due to the presence of 

 a poison in the blood. P., Toxic, a paralysis due to 

 the influence of a mineral or organic poison on some 

 part of the nervous system. P. vacillans. Syno- 

 nym of Chorea. P., Vasomotor, a paralysis of the 

 vasomotor center or the vasomotor nerves; it leads 

 to dilatation of the blood-vessels. P. venenata. 

 Synonym of P., Toxic. P., Writers', paralysis with 

 incoordination of the muscles of the wrist and fingers 

 from overuse, 

 aralysma mesentericum. Synonym of Tabes mesen-
