prevent further attacks of subarachnoidal hemorrhage. Although it is true that the danger of recurrent hemorrhage is greatest in the 2nd and 3rd week following the initial attack, the risk of another and frequently fatal hemorrhage is considerable even months and years later. In the series reported by Hyland 6 20 per cent of the patients who were discharged alive died later from a second hemorrhage. The experiences of this clinic reported in 1952 by Norlén 9 indicate an even greater mortality rate from new bleeding. Of 22 non-operated patients with saccular aneurysms

Thrombosis of Superior Sagittal Sinus

Caused by Trauma without Penetrating Injury

, who found that the mortality rate was 56 per cent when this complication was recognized. These observations indicate the serious effects of sinus thrombosis. Experimentation has been carried out on animals having a cerebral venous drainage different from that of man so that these results cannot be applied directly to human cases. 3 The most interesting approach to the problem has been that of Browder and Kaplan. 4 In 44 experiments carried out on fresh human autopsy specimens, they were unable to fill the superior cerebral veins by injecting a contrast medium

T his report is based on 105 consecutive Korean battle casualties of surgically verified transventricular wounds of the brain treated at Tokyo Army Hospital from September 1950 through March 1952. ‡ The overall mortality rate was 10.47 per cent. The value of early definitive neurosurgery is brought out by a comparison of the operative results before and after the establishment of an organized neurosurgical team in Korea in February 1951. DEFINITION AND DIAGNOSIS Wounds of the ventricle in this series were produced by missiles or foreign bodies passing

such cases were found in the literature. 1, 2, 4–10, 12, 14 The primary lesion is usually found in the lungs and bronchopulmonary lymph nodes, occasionally in the subcutaneous tissues (as the result of accidental penetrating injury), or in the gastrointestinal tract. 7 The infection then spreads by the hematogenous route and frequently produces metastatic intracranial lesions, notably brain abscesses. Among the 54 recorded cases there was proven intracranial involvement in at least 17 cases. The mortality rate of human nocardiosis is high; so far only one instance

minimal, the morbidity is insignificant, the mortality rate is low (1.8 per cent), and the results are as favorable as those obtained with other more extensive operations. Moore urged a greater utilization of this operation in suitable cases. Wilson and Pittman, 10 after their study of 200 cases, recommended transorbital leukotomy for all chronically disturbed patients when less strenuous forms of treatment have failed after 1 year's trial. It is apparent also from an abundant literature that prefrontal lobotomy has certain ameliorating tendencies in the care of the

neurological function as possible and to prevent the formation of decubitus ulcers and other complications that may retard a rehabilitation program. The mortality rate in this series was 1 per cent. As soon as the patient reached an equipped medical facility a complete physical examination was done, as penetrating wounds of the spinal cord were frequently associated with damage to additional areas. Of the 254 patients with penetrating wounds of the spine 87 (34.25 per cent) had associated chest wounds with hemothorax and/or pneumothorax, 23 (9.05 per cent) had bowel

cases, 5 died, giving a mortality rate of 14 per cent, and 2 were disabled. By comparison, cervical carotid ligation gave a mortality rate of 4 out of 18, or 22 per cent, with an additional 3 patients disabled. If we group the three categories in which a definitive attack was made on the aneurysm intracranially, namely: obliteration of the neck of the aneurysm, wrapping of the aneurysm, and ligation of the parent artery, we arrive at a collective mortality of 13 per cent and a disability of 7 per cent. There has been no report of a recurrence of rupture of an aneurysm

The 3 children with decerebrate signs for 11, 12 and 13 days recovered as completely as the 3 with signs for 10 hours, 36 hours and 5 days. The 3 with signs for 11, 12 and 13 days required about 3 months to recover from their spasticity, hyperreflexia and bilateral Babinski sign. In this small series, it is evident that the immediate mortality rate in the children is about the same

knowledge of specific aneurysms variously treated can help us determine the best method of management. Lastly, there is a distinct necessity for statistics on the mortality of each aneurysm problem when untreated. Certainly the mortality of treatment should not be greater than the mortality rate of the disease. From reports of relatively small series of surgically treated aneurysms, only a few conclusions can be drawn. This will depend upon what the reader is looking for as well as what the writer is trying to say. In this report the results of direct surgical attack in

nerve palsies are caused by increased intracranial pressure, per se, is challenged. Alternative possibilities concerning the mechanism of production of these paralyses are suggested. Sixth nerve palsies may be of localizing value. 2. Intracranial tumors were present in over 70 per cent of all the children. 3. The over-all mortality rate in the 122 cases is 70 per cent at the time of writing this article. This grave implication of an acquired disturbance in ocular motility makes careful evaluation of every patient mandatory. 4. There is a marked
