161 patients with tibia fracture were treated by closed intramedullary nailing at the department of Orthopedic Surgery, Eul-Ji General hospital, Dae Jeon, during 5 years from January, 1988 to April, 1993. 134 of these patients were performed with Kiintscher IM nailing and 27 patients with Ender nailing. Rigid IM nailing is the method of choice in tibia shaft fracture with rigid fixation, low complication, wide indication and early weight bearing, but the treatment of segmental fracture of the tibia will have many difficulties because of severe displacement, severe comminution, massive soft tissue damage and lack of blood supply at fracture site. Either antegrade or retrograde Ender nailing was of value for the management of segmental fracture which was too proximally or too dixtally located to insert interlocking screws, open fracture and soft tissue injury around Kiintscher insertion site. The result as fllows; 1. 43 fractures were open and 118 were closed. 69 fractures involved the distal portion, 55 fractures the middle portion, 13 fractures the proximal portion of the tibia and 24 fractures were segmental. 2. Among the 161 eases, 114 cases were male and 47 cases were female, the most common ages were ranged from 21 year to 30 year, involving 44 cases. 3. The most common cause was traffic accident. 4. Average intervals from injury to operation were 6.34 days(closed fracture) and 9.84 days(open fracture). 5. The mean durations of the bone union were 18.90 weeks(closed fracture) and 16.46 weeks(open fracture). 6. Complication included 7 cases delayed union, 3 cases nonunion, 8 cases superficial infection, 4 cases joint stiffness, 3 cases nail migration, 2 cases angular deformity, 2 cases rotational deformity, 1 cases osteomyelitis.

Spontaneous brain stem hemorrhage usually results in higher mortality and morbidity with poorer prognosis than any other intracranial vascular lesions in spite of meticulous medical or surgical treatment. We have experienced 86 cases of spontaneous brain stem hemorrhage who were admitted to Wonju college of medicine from January 1983 to Octobr 1995. 33 cases were treated with operation and 53 cases with non-operative treatment. The results were as follows: 1) Clinical parameters in both operative and non-operative groups showed no significant differences. 2) Treatment results were better in the operative group. Operative treatment is recommended in cases of GCS score below 7, hematoma size larger than 10ml, young age, and normotensive patients. 3) Appropriate operative approaches should be considered according to the patient's status. Recently, we most frequently performed a stereotactic approach. 4) Better outcome was obtained when the patients were operated from 72 hours to one or two weeks following the h emorrhage. 5) Hypertension, old age, and GCS score above 7 showed no statistical differences in terms of outcome between the operative and non-operative groups.

Henoch-Shonlein(H-S) purpura, or anaphylactoid purpura is a hypersensitivity vasculitis characterized by palpable purpura usually on buttock and low extremities; arthralgia mostly polyarhtralgia in the absence of frank arthritis; gastraintestinal involvement with colicky abdominal pain, nausea, vomiting, diarrhea, constipation and bleeding; and renal involvement, manifested chiefly by hematuria and proteinuria. Gastrointestinal involvement is seen in 70 percent of pediatric patients and one third of adult patients. Any portion of the gastrointestinal tract distal to the esophagus maybe involved, but most frequently affected sites are jejunum and ileum. We report one case of H-S purpura with duodenal involvement observed in 16, male patient.

Malaria is still a major health problem in Thailand and its incidence is currently rising in Korea. To identify a useful antigen for the diagnosis of malaria patients, a cDNA expression library from malaria parasites was constructed and screened out immunologically. One clone was selected in view of its predominant reactivity with the patient sera. The recombinant malaria parasite antigen (Pv30) with 27 kDa as a C-terminal His-tag fusion protein that was produced in Escherichia coli was identified through immunoblot analysis. The deduced amino acid sequence had the sequence homology with the merozoite surface protein 1 (MSP1) genes of Plasmodium falciparum and P. yoelii, each by 41% and 42%, respectively. Measurement of serum IgG and IgM antibody to Pv30 by enzyme-linked immunosorbent assay (ELISA) was evaluated as a serodiagnostic test for malaria patients in Thailand (endemic area) and Korea (recently reemerging area). The sensitivity of P. vivax, P. falciparum, and P. malariae was 96.3% (26 /27), 90.6% (29/32), and 100% (6/6), respectively, and the specificity was 63.5% (40/63) in Thailand samples. The sensitivity of P. vivax was 98.8% (88/89), and the specificity was 96.6% (86/89) in Korean samples. Pv30 appears to be a good and reliable recombinant antigen for serodiagonosis of malaria in a nonendemic area.

STUDY DESIGN: Twenty patients with spinal infection(tuberculous+pyogenic) in the lumbar spine were evaluated according to the surgical treatment methods using posterior instrumentation(pedicle screw) and conventional anterior curettage and interbody fusion method without posterior instrumentation. OBJECTIVE: The purpose of this study is to evaluate the efficacy of the method consisting of posterior instrumentation using pedicle screw and anterior lumbar interbody fusion. SUMMARY OF LITERATURE REVIEW: It has been reported that patients ended up with kyphosis had a higher incidence of back pain. MATERIALS AND METHODS: Twenty patients with spine infection in the lumbar spine divided into two groups depending on their use of posterior instrumentation in surgical treatment methods. One group consisted of 10 cases which were treated by conventional anterior curettage and anterior lumbar interbody fusion only(Group A) and the other groups consisted of 10 cases were treated by conventional anterior curettage and anterior lumbar interbody fusion with posterior instrumentation using pedicle screw(Group B) by a single surgeon. The clinical outcomes were evaluated using Macnab's classification and the radiographys were analyzed with respect to fusion status and sagittal angle. RESULTS: A solid bony fusion was obtained in Group B. But in Group A, 2 cases of bony resorption were occurred. The preoperative, immediate postoperative, and final follow-up sagittal angle in both groups were -7.4degree/ - 0 . 8degree, -19.0degree/ - 1 2 . 4degreeand -5.9degree/ - 8 . 6degree, respectively. There is a significant statistical difference in loss of sagittal angle correction between two groups(P<0.05). There is no complication related to the posterior instrumentation, but only 1 case of superficial infection was occurred. The clinical outcome which was evaluated by Macnab's method, there was no significant statistical difference between two groups(P>0.05), but exellent result was more common in Group B. CONCLUSION: This method which consist of conventional curettage and anterior lumbar interbody fusion with posterior instrumentation appears to be effective in stabilizing the vertebrae, and restoration and maintenance of physiologic lumbar lordosis. we would suggested this method for the surgical treatment in infection of lumbar spine.

In recent times, central nervous system(CNS) tuberculosis has been rare and the prevalence of the focal form, the tuberculoma, varies from 1 per 20 to 1 per 1000. CNS tuberculosis occurs as a result of hematogenous sparead from a primary focus, mostly pulmonary tuberculosis. It can be diffuse exudative leptomeningitis or a localized tuberculoma; the former is more common. We report a case of military cerebral tuberculosis in a 24-year-old female who had been having headaches for 4 months. Magnetic resonance imaging showed numerous small round Gadolinium-enhanced supratentorial and infratentorial lesions scattered throughtout the brain. Histologic examination confirmed well-defined tuberculous granulomas with central caseous necrosis in open biopsy, containing several acid-fast bacilli, the patient was treated with isoniazid, rifampin, ethambutol, pyrazinamide in combination with prednisolone.

PURPOSE: To analyze the results of radiologic and clinical outcomes after pedicle subtraction osteotomy in iatrogenic flat back syndrome. MATERIALS AND METHODS: We reviewed 12 surgical cases of iatrogenic flat back syndrome from January 1998 to July 2001 with a follow-up of more than 12 months. All cases were females and an average age was 59.8 years (48-66 years). An average follow-up period was20.4 months (12-37 months). Initial diagnosis were as follows: lumbar degenerative kyphosis, in 5 cases; spinal stenosis, in 5 cases; spondylolisthesis, in 2 cases. For clinical evaluation, 10-point pain scale and 5-point scale for activity level, cosmesis and subjective satisfaction were used. Lumbar lordotic angles and sagittal vertical axis (SVA) were measured. RESULTS: In radiologic results, an average lumbar lordotic angle at preoperative, postoperative and the last follow-up were 5.13+/-21.69 degree, -31.33+/-16.32 degree, -27.50+/-16.73 degree respectively. And average SVA at preoperative, postoperative and the last follow-up were 8.46+/-6.04 cm, 0.62+/-2.24 cm, 2.82+/-2.81 cm respectively. In clinical results, preoperative pain (6), activity (2) and cosmesis (1.8) were improved to 3.2, 3 and 3.2respectively at the last follow-up. Subjective satisfaction was 3.9. CONCLUSION: Pedicle subtraction osteotomy seemed to be very useful surgical option for improvement of clinical results through recovering of lumbar lordotic angle and sagittal balance in cases of iatrogenic flat back syndrome.

Methods:
Ambulatory patients who underwent single-level PVP for thoracolumbar OVF with a follow-up of at least 24 months were retrospectively reviewed. The patients were divided into two groups depending on the presence of symptomatic recollapse at the cemented vertebra: (1) recollapsed (RC) group and (2) noncollapsed (NC) group. The patient characteristics and radiographic measurements associated with sagittal imbalance were analyzed at each follow-up visit.
Results:
Overall, 134 patients (RC group, n=28; NC group, n=106) were enrolled. The mean fracture-free interval was 3.2 months (range, 1.2–25.1 months). The multivariate binary logistic regression analysis identified low bone mineral density (p =0.047), degree of dynamic mobility within the vertebra (p =0.025), and sagittal imbalance as significant risk factors for recollapse (p =0.013; odds ratio, 5.405). The progression of sagittal imbalance and thoracolumbar kyphosis (T10–L2) was more significant in the RC and sagittal imbalance groups than in the NC group (both p =0.000).
Conclusions
Sagittal imbalance, lower bone mineral density, and dynamic mobility within the vertebra are associated with the recollapse of cemented vertebrae following PVP. Sagittal imbalance, rather than local kyphosis or thoracolumbar kyphosis, is particularly significant in that it results in more progressive collapse and sagittal deformity and is accompanied by substantial back pain and neurological deficits. Therefore, a stricter and more active management, including anti-osteoporosis medication, is required for the treatment of OVF with sagittal imbalance of the spine.
