Low back pain is one of the most common symptoms in medical practice. Differential diagnosis of back pain is complicated, however. Self-reported pain intensity and disability may affect on the decision for diagnosis or therapy. Exaggerated symptoms may cause unnecessary investigations or even surgical interventions. Self-reported pain intensity and disability are not in proportion to the objective physical findings. We investigated the relationship between self-reported pain intensity or disability and sleep disturbance or fatigue. The study was conducted as a survey using a questionnaire from November 1997 to March 1998. The survey included consecutive 368 patients who visited the neurosurgical out-patient department complaining of low back pain. Pain intensity was measured by visual analog scale, and disability was assessed by Waddell's chronic disability index. By multiple regression analysis, self-reported pain intensity corresponded best with the sleep disturbance. Age and fatigue were also related to the pain intensity. There was no good agreement between pain intensity and region or duration of the pain, appetite or indigestion. Disability corresponded best with the sleep disturbance. Fatigue, appetite, and indigestion were also related to the disability. There was no good relationship between disability and region or duration of the pain, or age. Self-reported pain intensity and disability are related to the psychological distress represented as sleep disturbance, fatigue, poor appetite or indigestion. Inquiring about sleep or fatigue is important to understand the underlying psychological condition, which may exaggerate pain intensity and disability.

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.
MEDLINE

Acute subdural hematoma (ASDH), chronic subdural hematoma (CSDH) and subdural hygroma (SDG) occur in the subdural space, usually after trauma. We tried to find a certain relationship among these three traumatic subdural lesions in 436 consecutive patients. We included all subdural lesions regardless of whether they were main or not. We evaluated the distribution, age incidence and interval from injury to diagnosis of these lesions, and the frequency of new subdural lesions in each lesion. ASDH constituted 68.6%, SDG 15.8%, and CSDH 15.6%, Age incidence of CSDH was similar to that of SDG, but differed from that of ASDH. Mean interval from injury to diagnosis was 0.4 days in ASDH, 13.4 days in SDG, and 51.6 days in CSDH. Focal brain injuries accompanied in 37.5% of ASDH, 5.8% of SDG, and no CSDH. In ASDH, 2 recurrent ASDHs, 17 SDGs and 9 CSDHs occurred. In SDG, 3 postoperative ASDHs and 8 CSDHs occurred. In CSDH, 2 postoperative ASDHs, 2 SDGs and 1 CSDH occurred. These results suggest that the origin of CSDH is not only ASDH, but also SDG in upto a half of cases. SDG is produced as an epiphenomenon by separation of the dural border cell layer when the potential subdural space is sufficient. A half of CSDHs may originate from ASDHs. ASDH may occur in CSDH by either a repeated trauma or surgery. Such transformation or development of new lesions is a function of a premorbid condition and the dynamics between the absorption capacity and expansile force of the lesion.

Recent advances in diagnosis and therapy for head injury have brought some changes in concepts, definition of the terms, therapeutic methods and the duration of treatment. In medical certificates, the diagnosis and duration of treatment also need to be changed according to the new concepts. Mixed use of the terms according to the classic and the new concepts may cause confusion. We investigated with a questionnaire to assess the acceptability of the new concepts of head injury, and seeked for a plan to avoid possible confusion in medical certificates. We sent questionnaires for diagnosis and duration of treatment of 10 given examples of head injury to 367 neurosurgeons whose addresses could be identified. Questionnaires were answered by 52 neurosurgeons. The diagnosis described in the questionnaires showed wide variability with a range of 10 to 32 different descriptions, on average 16.8 different descriptions for each case. Duration of treatment also revealed great discrepancy. Coefficients of variation for duration of treatment varied from 33.44% to 54.37%. Cerebral contusion was the most commonly used term. It was described in every 10 given examples, and to take an average, 32.3 neurosurgeons used cerebral contusion or each case. To avoid possible confusion in medical certificates, it is necessary to make a guide for medical certificates for head injuries according to the new concepts, and a chance of training of this guide should be provided.

Development of new surgical devices and approaches for management of injuries to the cervical spine has offered various methods of treatment available. Making it is not easy in choosing the most suitable method of treatment. We present our experience and results of 90 operations performed during the past eight-year-period(1986-1993) including 10 halo-vest applications. The timing of operation was within 7 days posttrauma in 34.2%, 8-14 days in 27.4%, 15-28 days in 1.0%, and over 28 days in 27.4%. In 18 cases of upper(C1-3) cervical spine injuries, 23 operations were performed, all approached from the posterior. In 5 cases of lower(C4-7) cervical spine injuries, 67 operations were performed, the anterior approach used in 33 patients and the posterior approach in 18 patients. Halo-vest was applied in 6 patients with upper cervical spine injuries and in 4 patients with lower cervical spine injuries. The halo-vest was inadequate in maintaining the stability of the injured spine in 5 out of 0 cases. The complication rate was 23.3% in postrior approaches and 32.4% in anterior approaches. Overall, 27 complications(0%) occurred in 90 operations, and the reoperation rate was 16.4%(85 operations for 73 patients, except for the halo-vest applications). Internal fixation with a variety of devices has become a popular procedure for ervical spine injuries. Despite the popular and wide usage of such devices, the occurrence of complications and the need to reoperate has rendered the procedure to be applied with much caution regarding its technical aspects and possible problems it may pose. In our study, the rate of reoperation and complications following such procedures were quite high. We conclude that in choosing the most proper surgical approach for ervical spine injuries with minimal occurrence of any complications, a stringent criteria should be adhered to rather then easily select the more fashionable, new of fancy devices over the traditional techniques.

Although the prevalence of infectious disorders has been decreased, tuberculous infections are still common in this country. Therefore epidemiological data for the correct diagnosis of some spinal infections and proper selection of susceptible antibiotics are necessary. We presented a series of 40 patients with primary spinal infection dated from January 1990 to December 1994. Tuberculosis was the most common infection constituting 85% of this series, while pyogenic infection constituted only 10%, and primary discitis shared 5%. In a half of the tuberculous spondylitis, there were histories of previous tuberculosis except the vertebrae. We could identify the pathogenic organisms in only 47.5% o the cases(in 4 of 6 pyogenic infection and 15 of 34 tuberculous infection). Since it is difficult to differentiate the pyogenic and tuberculous infections by clinical or radiological features alone, some pyogenic infections might have been regarded as tuberculous, although the pyogenic spinal infections are rare. Nevertheless the tuberculous spinal infection outnumbered pyogenic ones in this country, which is similar to the patterns of other third-world countries. Therefore, correct identification of the microbial agent is important not only for the proper treatment but also to evaluate the patients of primary spinal infections in this country.
