OBJECTIVE: The aim of this study is to determine the factors influencing the surgical outcome following craniotomy for head injury and to establish the criteria for surgical intervention in the age of 65 years or older. METHODS: We retrospectively investigated the mechanism of injury, types of computed tomography lesions, Glassgow coma scale(GCS) score at admission, pupillary reactivity, past medical history and surgical outcome following craniotomy in the elderly during 8 year period. RESULTS: There were 35 men and 21 women with a mean age of 70.7 years(range 65-87 years). The mortality rate at discharge was 58.9%. Good outcome was achieved only in 25 percent of the patients. The cause of injury did not affect on the surgical outcome. All of 19 patients with GCS of 5 or less at admission had poor outcome. Outcome was significantly worse in older patients(more than 75 years) compare to younger patients(less than 75 years). Ninety percent of the patients with pupillary abnormality had poor outcome, whereas 57.7 percent of the patients with bilateral reactive pupil had poor outcome. Past medical history did not affect on the surgical outcome following craniotomy. CONCLUSION: Surgical outcome is unexceptionally poor in the elderly head-injuried patients if the age is 75 years old or older, the GCS is 5 or less and the pupil is bilaterally dilated. Craniotomy under those circumstances is not desirable.

The most feared complication of left ventricular thrombus (LVT) is the occurrence of systemic thromboembolic events, especially in the brain. Herein, we report a patient with severe sepsis who suffered recurrent devastating embolic stroke. Transthoracic echocardiography revealed apical ballooning of the left ventricle with a huge LVT, which had not been observed in chest computed tomography before the stroke. This case emphasizes the importance of serial cardiac evaluation in patients with stroke and severe medical illness.

It is never easy to assess the rate of disability from spinal injuries objectively. One reason is that the pain is an unmeasurable subjective symptom, and the other is that the disability is usually not confirmed by or correlated with radiological or laboratory examinations. The disability is an essentially subjective inconvenience or limitation, which is hard to measure objectively. However, compensation or reparation requires a scale to measure this unmeasurable disability, even with a universal validity and equity. There are several guidelines or criteria for a quantitative assessment of the disability. They differ from each other and have their own advantages and disadvantages. This difference may cause confusion or inequity. To improve the validity and equity, we propose a new design for the disability evaluation in patients with spinal injuries. We reviewed the Korean law for compensation in industrial accidents, McBride's disability table, the guideline proposed by American Medical Association, and a impairment rating table. Disabilities resulting from spinal injuries were classified into three types, i.e., morphologic sequelae(deformity), functional sequelae(dysfunction), and others. Only objective findings were considered as criteria for rating the disability. Disability resulting from deformity were rated from 0 to 20% by the degree of compression. Dysfunction can be rated by the number of lost motion segment from 10 to 60%. Disability from other compensable spinal pain were rated by objective physical findings or neurologic deficit from 0 to 25%. By eliminating the subjective or intentional complaints, this design can be a useful method minimizing the differences from the multiple examiners.

VDT syndrome is the disease entity that affects many workers on the various visual function as well as on some general health conditions including neurologic, circulatory and musculoskeletal system and it tends to increase day by day. We performed a series of investigation to evaluate the influences of VDT work on the subjective symptoms by means of questionnaire application with the control of non-VDT workers. It revealed that the susceptibility in occurrence of impairment of ocular functions like asthenopia as well as the disturbances of musculoskeletal circulatory, gastrointestinal, and nervous systems were more pronounced in the VDT workers' group than the control group, and the environmental factors like working hours, air pollution, and noise also contributed for the worsening of the ocular and systemic symptoms. It is suggested that the improvement of operating environment by the implementation of comprehensive epidemiological study in association with the improvemental task of working situations and working times in long term advocated would decrease the VDT syndrome among VDT workers.

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.

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.

Mortality after cervical spine injury is reportes as high as 15~30%, and it is intimately related to the initial cardiopulmonary function. We analysed the cause of death and initial cardiopulmonary function in 30 patients who expired at Soonchunhyang University Chonan Hospital after cervical spine injury between 1986 and 1993. Overall 42 patients(20.5%) expired in 205 patients with cervical spine injuries. Except 12 cases with concomitant fatal head injury and/or multiple systemic injuries, the mortality rate of cervical spine injury was 15.5%. It was 28.9% in cases with cord injury, and 2.1% in cases without cord injury. Male to female ratio was 5 : 1. Fifth to seventh decades constituted 63.3%. Common causes of spinal injury were in-car accident(46.7%) and fall/slip(36.7%). The level of spinal injury was above C5(upper cervical group ; UCG(55.6%) than the LCG(25.0%). Associated injuries were found in 66.7%, and the head injury was the most common one. The injury severity score was over 25 in 93.3%. The higher the score, the earlier the patients expired(Fisher's test, P<0.05). On arrival, hypotension(systolic blood pressure below 70 mmHg), bradycardia(less than 60/min), and respiratory arrest was found in 23.3%, 26.7%, and 16.7%, respectively. The episode of bradycardia was found in 56.7%. It was more common in cases of the early death(69.2%) than those of the late death(47.1%). Hypoxia, hypercarbia, and acidosis was observed in 19.2%, 7.7% and 5.38%, respectively. Respiratory failure was responsible for the majority(86.7%) of death. In UCG and cases of the early death, primary respiratory dysfunction was the main cause of death, while in LCG and cases of the death, pulmonary complication was the major reason(Fisher's test, P<0.01, respectively.
