In fact, Mendelssohn found a complete flaccid paraplegia with urinary retention, without fever or pain. Knee-jerks and Achilles jerks were absent, and there was a slight extension of the great toe on plantar stimulation. There was disorder of sensation, with heat sensibility abolished, painful points poorly localized, and position sense poor. Electric reactions normal. Pain on pressure in and about the lumbar vertebral region. Cerebrospinal fluid showed lymphocytosis and an excessive albuminosis. This paraplegia lasted six weeks. At the end of May, the patient began to be able to move his toes and to lift his heel. Improvement was gradual and progressive. Early in June he could walk if supported. The weak knee-jerk then began to reappear and the urinary retention gradually disappeared. This patient was not hysterical, although a bit emotional. Perhaps, according to Mendelssohn, an organic lesion was grafted on a neurosis. Perhaps the spinal lesion was infectious. At any rate, a presumably organic paraplegia had recovered in two months and a half. Shell-explosion: Meningeal hemorrhage: Pneumococcus meningitis. =Case 112.= (GUILLAIN AND BARRÉ, August, 1917.) An infantryman, 20, came to the Sixth Army Neurological Center, October 13, 1916, as a case of “choluria, due to shell explosion; epistaxis needs watching.” He was somnolent, had waked vomiting, pulse 108. Kernig’s sign, defensive movements of the legs on stimulation, with flexion of leg on thigh and of thigh on pelvis, plantar reflexes flexor. Puncture showed typical meningeal hemorrhage. Two days later, temperature 40, pulse 70, that is to say, a bradycardia in proportion to the fever. Vomiting, pulse persisted. Next day the patient was moaning and semi-delirious and showed stiff neck, Kernig’s sign, accentuation of vasomotor disorder, plantar response flexor with leg retracted, thigh flexion both homolateral and contralateral. The spinal fluid upon the next day, that is, four days after his arrival at the clinic, showed a purulent fluid in which there was an excess of albumin, no sugar, diplococci extracellular (proving on culture to be pneumococci and able to kill a mouse in twenty-four hours). As a rule such hemorrhages remain aseptic, and in fact meningeal hemorrhage is said by Guillain and Barré to have, as a rule, a favorable prognosis. The above described case was the only one of infected meningeal hemorrhage that had occurred in the Sixth Army Neurological Center. ANTEBELLUM cortex lesion: right hemiplegia; recovery. Struck by shrapnel on right shoulder: Athetosis. =Case 113.= (BATTEN, January, 1916.)
