present before. Physical Examination . The skin over the left fronto-temporal area was scarred and atrophic due to the extensive radiotherapy. Beneath the atrophic skin an irregular hyperostosis was palpable. There was, in addition, a hard bony lump in the left parasagittal region above the scar. The general examination was otherwise normal. The neurological survey revealed moderate weakness of the right lower limb, most marked in the dorsi-flexors of the foot, hyperactive right knee and ankle jerks, and a positive right Babinski sign.

.2%) 1 (1.5%) Table III reveals a striking percentage parallel between the two groups answering the questionnaire. It indicates that any essential difference probably is that private patients are forced to continue work in spite of their complaints, while patients on compensation are relieved of that necessity. It shows, also, that 75 per cent of compensation patients are removed from the compensation rolls following surgical removal of their protruded discs. SUMMARY A questionnaire survey was made of the results of surgical treatment of

. in diameter. There were no other abnormalities in the skull films. The appearance of the lesion was such as to suggest the possibility of malignancy. Complete survey films of the skeleton were carried out without the finding of any other abnormality. A complete examination of the urological system, including retrograde and intravenous pyelograms, was normal. Laboratory Data . Red blood cells 4,730,000, hemoglobin 90 per cent, white blood cells 8,600. Differential count: Polymorphonuclears 54, lymphocytes 43, monocytes 1 per cent and eosinophiles 2 per cent

of nerve regeneration, have led to important insight into the prerequisites for optimum nerve restoration. Arterial sleeve splicing complies with more of these prerequisites than do other methods, and this has been the basis of its success. But further application of the lessons thus learned gives promise of even more substantial improvements, and sleeve splicing may eventually be superseded by some other, more meritorious procedure incorporating its experiences. The emphasis lies more on the principle than on the current form of its application. An unbiased survey

of the lesion to afford an adequate precedent for therapy. For these reasons, we have undertaken a description of three patients with clear-cut fibrosarcomas of the dura mater in childhood. Two of these presented similar clinical syndromes and pathological findings, while the third, histologically identical with the other two, was different in gross appearance, clinical behavior and prognosis. In making a survey of the literature, it soon became apparent that a precise evaluation and classification of many reported cases would be difficult, owing to the brevity

the evaluation of dizziness. In general there are three schools of thought—one group who consider dizziness, as well as the other symptoms of the post-traumatic syndrome, to be of psychogenic origin; another group who report it to be exclusively of physiogenic origin; and others who emphasize the importance of both types of factors. Grove 6 in a survey of the subject remarked that post-concussional vertigo of vestibular origin is characterized by a systematized dizziness accompanied by nystagmus brought on by movements of the head. He considered other types of

possible through homografts to a degree comparable to that noted in autografts and indeed after simple nerve suture. 6 These studies have been fully confirmed and amplified by our English colleagues in a series of recent publications. 1, 3, 7 In spite of these stimulating experimental reports, a survey of the literature devoted to human nerve grafting does not encourage the use of homografts, nor indeed is the reviewer impressed by the number of successful autografts properly evaluated and reported. This is particularly evident in the grafting of large human nerves as

extension. A brief reference to these unusual extensions in Dr. Cushing's cases is also made in the survey of the Brigham series made by Dott and Bailey. 6 By far the most important paper on this subject was given by Jefferson 9 in 1940 in his President's address before the Royal Society of Medicine. Unfortunately this article has been published only in the Proceedings of the Society, so it can have come to the attention of but few medical readers in this country. Jefferson cites three main factors in the production of extrasellar extensions: (a) the growth urge of the

work was reported in 1934. 10 This is not a statistical survey, since a majority of the patients were referred to the neurosurgeon as a last resort. However, a certain number among them were treated from the beginning with the orthopedic surgeon in charge. In the following few pages we propose to discuss this series and the lessons learned in their management. Nerve injury associated with fracture and dislocation may be primary or secondary, as has been emphasized by almost all authors. The diagnosis of primary nerve injury is seldom made, and the physician

The blood vessels at the base were normally distributed and were of normal appearance. Microscopic Observations . Survey sections from the white and gray substance of both hemispheres, from the hypothalamus, and the midbrain were stained with hematoxylin and eosin and with cresyl violet, and were also prepared by the Loyez and Bodian methods. The white matter of the right hemisphere
