To determine which factors influence the successful results in the patients who underwent lumbar arthrodesis with TFC(threaded fusion cage) at L34 to L5S1 intervertebral space. 20 subjects were analysed in retrospective method. Between January 1997 and April 1998, interbody fusion with TFC was undergone on 20 patients, and among them, 19 patients(95% ) were confirmed to have bone fusion at 12 months after operation. All patients were classified into group A(satisfactory results) and group B(unsatisfactory results) according to comprehensive low back questionnaires from their answer. They were checked with reference to intervertebral disc height and scoliotic, and lordotic angle with Cobb's method in the anterioposterior and lateral lumbar spine films before/after operation, and TFC diameter and length were categorized. In group A, 11 cases(55%) of "excellent" results and 5 cases(25%) of "good" results were included. In group B, 2 cases(10%) of "fair" results and 2 cases (10%) of "poor" results were included. In the lateral projection of group A and B. the mean preoperative disc height were 9.88±2.69mm and 10.45±2.39mm. Twelve months after operation, the mean disc height of group A was significantly increased to 14.11±2.14mm, but that in group B was not significantly increased only to 11.50±2.52mm. Preoperatively, the measured scoliotic and lordotic angles between L1 and S1 by Cobb's method were similar in both groups, being 4.18±3.58 and 26.75±6.64 degree in the group A, 3.50±2.65 and 33.25± 13.10 degreee in the group B. Twelve months after operation, the angles for group A were significantly improved to 0 and 48.13±11.83 degree, but in group B, not changed into 4.50±4.79 and 33.75±10.31 degree. The mean diameter and length of TFC in group A were, in each, 15.62± 1.09mm and 24.44±2.39mm but, 12.50±1.00mm and 21.00±0.00mm in those of group B. For successful results after TFC interbody fusion in the lower lumbar spine, recovery of narrow disc space, scoliosis, lordosis accompanied by solid arthrodesis were necessary. The authors propose that relatively larger-sized TFC should be profitable for those cases.

Granulocytic sarcoma, a rare extramedullary solid tumor arising from early myeloid precursors, is capable of invading the meninges or the brain parenchyma. The tumor may occur during or after the onset of systemic myelogenous leukemia. On rare occasions, the tumor may evolve before the onset of systemic myelogenous leukemia. Children are affected more often than adults, but sex is not related. Although no definite target area of the brain can be demonstrated, there may be some predilection of the tumor for the posterior fossa. The authors report a case of 4-year-old-boy with granulocytic sarcoma occuring in the posterior fossa presenting with gait disturbance and torticollis. The patient was treated by surgical removal of the tumor, thereby avoiding the potentially lethal complication of a posterior fassa mass. This rare case is reported together a review of the literature.

12l patients with cervical(45 patients). thoracolumbar(76 patients) compression or mild burst fractures from January 1984 to December 1994 were studied : 98 patients were treated postural reduction with hyperextension posture and 23 patients were with postural reduction and surgical methods We compared the initial and post-reduction compression height ratio. wedge angls and kyphosis angle of compression fractures The results were not only expansion of a compressed vertebral body but also successful fusion. The neurological recovery status according to Frankei classification was also improved after postural reduction. Most of the compression fractures or stable burst fractures of the cervical. thoracolumbar spines can be restored by the postural reduction

Five separate incidences of patients with cerebrovascular disease(CVD) were revealed among 555 craniocerebral traumatic victims between 1991 and 1992. The 5 cases of with cerebrovascular disease revealed included 3 aneuryms. 1 arteriovenous malformation and 1 spontaneous intracerebral hematoma caused by angiographic study. The frequent use of computerized tomographic scans in the evaluation of head-injured victims can well demonstrate an intracerebral hemmorrhage, but may not get able to direct the associated cerebrovascular disease;whereas the efficacy of angiography, on the contrary, has been losing its popularity as diagnostic armamentarium. The importance of angiographic study should be considered, if clinical signs and/or brain CT ideate the possibility of cerebrovasular disease even during the course of head injury management.

Oral & maxillofacial infections are most commonly odontogenic in origin. Although such infections are usually self-limiting, they may occasionally spread deeply into fascial spaces or planes far from the initial site of involvement. If early diagnosis and appropriate therapy is delayed, complications such as mediastinal extension, retropharyngeal spread and airway obstruction could happen to the patients. For the study of the microbiology, we have retrospectively analysed the oral & maxillofacial infected patients in the Dept. of Oral & Maxillofacial Surgery, In-Ha University Hospital from 1997 September to 2000 April. The results were as follows 1.The male patients were more common than female, with male 61.9% and female 38.1%. 2.Dental originated infections were most common cause with the incidence of 62%. 3.Most common fascial space involved was buccal space 42cases(37.2%) followed by submandibular space 13cases(11.5%), infraorbital space 13cases(11.5%), masseteric space 11cases(9.7%) , periapical abscess 11cases(9.7%) . 4.The causative organisms isolated from the pus culture were Gram Positive Bacterial species, which were 46cases(31.9%) of Streptococcus viridans, 16cases(8.6%) of α and β-hemolytic streptococcus, 4cases(3.1%) of Strep.-group D non enterococci, 7cases(5.1%) of Staphylococcus Coa. Neg., 5cases(3.9%) of Staphylococcus aureus, 3cases(2.3%) of Enterococcus faecalis, 1case(0.8%) of Bacillus species, 1case(0.8%) of Peptostreptococcus, 1case(0.8%) of Clostridium and Gram negative bacterial species, which were 4cases(3.1%) of Acinetobacter baumannii, 2cases(1.6%) of Pseudomonas aeruginosa, 2cases(1.6%) of Burkholderia cepacia, 1case(0.8%) of Neisseria species, 1case(0.8%) of Klebsiella pneumoniae, 1case(0.8%) of Klebsiella oxytoca, 1case(0.8%) of Escherichia coli. 5.In drug sensitivity test, high resistant tendency was found in Penicillin system(Penicillin G 83.3%, Ampicillin 60%) and Aminoglycosides (Gentamycin 50%, Tobramycin 45.5%), but tertiary Cephalosporin system(Cefoperazone 9.1%, Ceftazidime 18.2%), and glycopeptides system (Teicoplanin 0% , Vancomycin 0%) showed lower resistancy.

Objectives Theory of mind (ToM) is the ability to conceptualize other people's mental states in order to explain their behavior. This study compared the ToM ability of schizophrenia patients, their first-degree biological relatives, and healthy controls. Methods ToM animation test was administered to schizophrenia patients (N=28), their healthy first-degree relatives (N=26), and healthy controls (N=28). The Korean version of schizotypal personality questionnaire (SPQ) was used to assess the schizotypal personality trait of all three groups. Results Schizophrenia patients and their first-degree relatives showed decreased accuracy on ToM animation test compared to healthy controls [F(2,78)=29.75, p<.001]. Additionally, first-degree relatives performed worse than the control group and better than schizophrenia patients. First-de-gree relatives had similar SPQ scores compared to healthy controls but showed decreased ToM accuracy compared to healthy controls. Conclusion ToM deficits in schizophrenia patients are apparent. The ToM deficit in first-degree relatives of schizophrenia patients raises the possibility that ToM deficit may be a endophenotype for schizophrenia pathology.
