Diseases of the nervous system : a text-book of neurology and psychiatry . n to it chiefly by French neurologists,notably Dejerine (1905) and his pupils.^ Symptoms.—These are neuralgic pains, which are usually severe,yet very variable. They usually occur in crises, and are sticking 1 Dejerine et Thomas. Maladies de la moelle epiniere, 1909. RADICULITIS 275 and lancinating in character, at times extremely intense; not infre-quently resembling the pains of tabes. The pains have a tendencyto remit and then to recur at shorter intervals, leaving a certainsoreness behind. The nerve trunks are usually not markedly is usually a marked hyperesthesia over the radicular segment,It does not follow the peripheral distribution as in a non-radicularneuralgia. This hyperesthesia is usually followed by an anesthesiato both epicritic and protopathic sensibility, and occasionally bonysensibility is involved as well if the inflammatory reaction is sensibility may be so involved as to cause and acroparesthesise are Figs. 131 and 132.—Topography of the sensory disturbance in a syphilitic radiculitis(type Klumpke). The Cs and Di, 2 distribution are involved. (Dejerine.) It is essential that these features, which may be found in otheraffections, be radicular in their distribution. They are not segmentary,i. e., involving the hand, the forearm, or the arm; nor do they followthe peripheral nerve distribution. They are distributed in long bandsdown the arm or the leg, corresponding to the root segments involved.(See Figs. 133, 134, and also Figs. 11 to 16, and Plates X and XI). It is a striking fact that sneezing or coughing may bring on a par-oxysm of pain in the cervicodorsal plexus, and coughing and strainingat stool may bring on pain in a sciatic radiculitis. The knee-jerks are primarily exaggerated, later diminished or lost. In the upper extremity it is rare to find a pure radiculitis, i. e., one 276 AFFECTIONS OF THE PE
