PURPOSE: This study was performed to examine if CT classification of renal blunt injury could aid in expectation of hemodynamic stability and clinical decision of whether to intervene surgically. MATERIALS AND METHODS: Over a 80-month period between July 1987 and March 1994, 41 patients were admitted to our hospital with the diagnosis of renal blunt injury. The renal blunt injuries were classified on Fedede's three-point scale CT classification methods :grade I, contusion, intrarenal hematoma, segmental infarction, and small subcapsular hematoma;grade II, complete or incomplete laceration, large subcapsular hematoma, and renal fracture;grade Ill, shattered kidney and renal pedicle injury. Hemodynamic stability, treatment method and clinical outcome of the patients with different CT grade were analyzed retrospectively. RESULTS: All 34 patients with grade I or II CT findings were hemodynamically stable and were successfully managed with conservative method. Among 7 patients with grade III CT findings, 6 patients were hemodynamically unstable. Out of the 6, One patient with grade IIIb or renal pedicle injury was expired before surgical intervention due to ischemic shock. Four patients were intervened surgically with one failure to thrive. The remaining one patient refused to be intervened surgically, and was discharged against medical advice. Only one out of 7 patients was hemodynamically stable and was managed conservatively. CONCLUSION: The patients with grade I or II CT findings are prone to be hemodynamically stable and to be managed with conservative method. But the patients with grade III CT findings are more likely to be hemodynamically unstable. Therefore patients with grade III CT findings should be closely monitored and be pre- pared for the possibility of immediate surgical intervention

Primary malignant melanoma arising from the leptomeninges is a rare entity. We report two cases of primary intracranial melanoma developed in one aged 65 years female and the other 70 years male. One case died 2 years after the operation, and the other case is still living more than 1 year after operation. Both cases seems to have a relatively long survival. The literature on this subject is briefly reviewed.

We examined the initial CT findings of the early(within on week) death after head injury, retrospectively. The patient population consisted of 182 patients who were admitted to the Soonchunhyand University Chonan Hospital, and were examined by CT, from August 1986 to May 1990 after head injury. We compared clinical features and radiological findings between the group of focal lesion and the group of diffuse lesion. The focal lesion was found in 47.8%, while the diffuse lesion was found in 45.6%. Statistically significant differences were found in the age, Glasgow Coma Score(GCS) on admission, injury Severity Score(ISS), hypotension, and hypoxia. The focal lesion was more common in the aged, while the diffuse lesion was common in the young(less than 40 years of age). Patients with high GCS(more than 8) constitued 25.3% of the focal lesion, while only 6.0% of the duffuse lesion had the high GCS. ISS was higher than 30 in 67.5% of the diffuse lesion, while 32.2% of the focal lesion had ISS of 30 or more. The causes of injury was pedestrian traffic accident in 46.5% and passanger's traffic accident in 31.8%. Midline shift(more than 3mm), compressed ventricles, and obliteration of the suprasellar cistern and quadrigeminal cistern were observed in 34.1%, 82.4%, 67.6%, and 58.2%, respectively. Lesions with severe midline shift were focal in 93.1% and lesions without midline shift were diffuse in 88.4%(P<0.005). Cranial vault fracture was noticed in 68.2%, and basal skull fracture was found in 28.8%. The frequency of basal skull fracture was high in the diffuse lesion(P<0.005). In this study, we could presumed that 17.2% to 25.3% of the patients with focal lesions could be saved, if proper treatment was given. Since the diffuse lesion was responsible for nearly half of the early death after head injury, proper treatment or prevention should be made. Prevention of the diffuse lesion seems to be possible by correction of hypotension and hypoxia for the diffuse lesions were intimately related to them. At any event, further studies on the diffuse brain injury are required.

The following is our report a series of 220 patients who visited the neurosurgical out-patient department from January 1994 to June 1994 complaining of low back pain. We investigated how they were treated and what was the outcome on December 1995. Three certified neurosurgeons had managed these patients. Although the patients were not significantly different in terms of age, sex, and the duration of pain, the diagnostic methods(p<0.005), impression(p<0.01), and the methods of treatment(p<0.01) differred from doctor to doctor. The rates of admission and operation were 11.8% and 7.3%, respectively, and found to be consistent among doctors. We conducted telephonic interviews of 123 patients during December 1995 with the following outcome : improved in 69.1%, unchanged in 22.0%, and aggravated in 4.1%, together with six(4.9%) deaths. The cause of death was cancer in four cases, respiratory failure in one, and unknown in one. Sixteen patients underwent surgery in this hospital, while the other 12 patients were operated on in other hospitals. The outcome was favorable when 1) the patients were female, 2) the age was 21-40 years old, 3) presence of sciatica, 4) the duration was 1 week to 3 months, 5) the diagnostic impression was herniated lumbar disc, 6) drugs were not prescribed, and finally 7) managed by senior doctor. However, these differences were statistically not significant(p>0.1). Although low back pain is a very common complaint, there was enormous ambiguity with respect to its diagnosis and management. Neverthless, the outcomes were not significantly different. Despite the above, we still feel that low back pains should be more systematically classified and precisely dignosed. Also the therapeutic efficacies of different modalities of treatment should be critically reviewed.

Tables and figures are very useful tools to support the author's point or opinion. It should be made according to instructions for the authors of the given Journal. The Journal of Korean Neurosurgical Society requires simple and clear English titles and explanations for the tables, figures and photos, which should be attached at the end of the manuscript. The author examined correctness of the tables and figures in the Jormnal of Korean Neurosurgical Society Volume 26. In 1997, 240 articles published in the Journal of Korean Neurosurgical Society. All 240 articles used at least one table or a figure. Tables were used in 157 articels, of which 107 articles(68.2%) have at least one incorrect table. Blanks in the field(26.2%), omitting the column headings(25.2%), and incorrect footnotes(19.6%) were common errors in the tables. Figures were used in 208 articles, of which 31 articles(14.9%) have at least one incorrect figure. Identifiable name or hospital number(35.5%), wrong numbering(29.0%), and duplication of tables and figures (19.4%) were common errors in the figures. It is important for the contributors to keep the instruction. To improve the quality of the journal, proper education for the manuscript and meticulous review of an article are necessary. It may be useful to illustrate an example of a table in the instruction of the Jormnal of Korean Neurosurgical Society.
Education

The Journal of Korean Neurosurgical Society is the unique official journal of Korean Neurosurgical Society. However, it is not yet indexed in the Index Medicus or Medline. The author investigated the accuracy of the references in the Jourmnal of Korean Neurosurgical Society Volume 26 and frequency of citation. In 1997, 240 articles published in the Journal of Korean Neurosurgical Society. The average number of references and frequency of citation were evaluated. Accuracy of the references was examined according to the instructions for the contributors which was revised at 1995. The references were described correctly in 104 articles(43.3%). In 136 articles(56.7%), there was at least one descriptive error. The most common error was an incorrect abbreviation of the journals, which was found in 87 articles (36.3%). Incorrect description of the books or chapters in a book was found in 62 articles(25.8%). Describing more than three authors was found in 31 articles(12.9%). There were some other faults, such as an incorrect author's name, omitting an article in the references, wrong order, or different description of the pages. The average number of references were 27.1 in total. The average number of Korean references were 1.3, and that of the Journal of Korean Neurosurgical Society was 0.93. It shared only 3.43% of all references. Only 108 articles (45.0%) cited at least one Korean reference. The number of articles citing the Journal of Korean Neurosurgical Society was 97(40.4%). It is an honor to publish an article in the official journal of his own academic society. However, submitting an articles which do not follow the instructions and publishing an inadequate article without proper correction would pull down the quality and the value of the journal. It is important to teach the way how to prepare an article. Meticulous review of an article is essential to improve the quality of the journal. It is also necessary to monitor the reviewer's missing.
