February 19, no mental disorder. Headache and lassitude. Neck stiff, Kernig’s sign marked. Lumbar puncture yielded a fluid now puriform; antimeningococcus serum injected. February 20, lifting the head produced opisthotonos. Labial herpes. The fluid yielded, besides meningococci, also endothelial cells. Serum injected. February 21, fibrin in fluid; serum injected. February 22, no head symptoms. Herpes more intense, involving also arms. Tongue coated. Temperature 37.5, evening 38.3. February 23, meningococci and lymphocytes in fluid. February 24, left knee swollen. Serum injected; puncture fluid showed meningococci and polynucleosis. Fluid from knee showed polynuclear cells without organisms. February 25, patient reached evening temperature of 39.5; serum injected. A few meningococci, altered polynuclear leucocytes. February 26, patient rigid, tongue coated, serum injection. Rare meningococci, degenerated polynuclear leucocytes. February 27, rigidity decreased, evening temperature 37.7. February 28, Kernig’s sign absent. Herpes dry. Serum injection. Fluid clear; lymphocytes and polynuclear cells; no meningococci. March 6, painful inguinal gland on the left side. March 7, epididymitis left (mumps two years before, with headache two weeks and double orchitis). March 9, serum eruption. March 17, epididymitis practically absent. Lymph node painful. Later data impossible to get, except that there was apparently an arthritis of the hip and a sacral decubitus with eventual recovery. Shell-explosion: Meningitic syndrome, fourteen months. =Case 109.= (PITRES AND MARCHAND, November, 1916.) A soldier sustained shell-shock at the distance of a meter at Saint-Hilaire, September 26, 1915. He lost consciousness and blood flowed from his ears. He arrived, September 28, at the neurological center in Bordeaux in a semistupor, knowing that he had been shocked and had lost consciousness. He groaned, cried out, and kept stroking his head with his right hand; lay on the right side; showed Kernig’s sign right, ptosis, and stiff neck. Headache was increased on moving and noises. Patient constantly asked for food, but refused to drink. Lumbar puncture yielded a yellowish fluid, due to laked blood. October 3, headache, ptosis, left internal strabismus, temperature 38.5. October 4, lumbar puncture, slightly blood-tinted fluid. October 5, improvement; gap in memory for period since shock. No strabismus, ptosis diminished, temperature normal, improvement continued. Kernig’s sign and headache persisted. He lay doubled up on the right side, eyes closed, right hand on pillow. Defense movements on touching the neck or occipital region. The condition of semistupor often passed off in the afternoon, when he could talk, write or play cards. He had always smoked, even at the beginning of his disease. Lumbar puncture yielded a normal fluid December 12, 1915. He was sent February 23, 1916, to a hospital in the country, but came back May 9.
