The present study was performed to evaluate the effect of tetracycline-HCL on the change of implant surface microstructure according to application time. Implant with pure titanium machined surface, double coated FBR(R) surface and oxidized CellNest surface were utilized. Implant surface was rubbed with 50mg/ml tetracycline-HCL solution for 1/2, 1, 1 1/2, 2 and 2 1/2min. respectively in the test group. Then, specimens were processed for scanning electron microscopic observation. The results of this study were as follows. 1. Both test and control group showed a few shallow grooves and ridges in pure titanium machined surface implants. There were not significant differences between two groups. 2. The double coated FBR(R) surfaces showed fine crystalline structures. The roughness of surfaces conditioned with tetracycline-HCL was lessened relative to the application time. 3. The oxidized CellNest surfaces showed the porous structures. The surface conditioning with tetracycline-HCl influenced on its micro-morphology. In conclusion, the detoxification of the affected implant surface with 50mg/ml tetracycline-HCL should be applied respectively with different time according to various implant surfaces.

OBJECTIVE: The objective of this study is to evaluate the clinical and angiographic outcomes after primary balloon angioplasty in patients with symptomatic middle cerebral artery (MCA, M1 segment) stenosis refractory to medical therapy. MATERIALS AND METHODS: Eleven patients with intracranial stenosis were treated with primary balloon angioplasty. All patients had MCA stenosis with recurrent transient ischemic attack (TIA). The indication for balloon angioplasty was patients with significant MCA stenosis: 1) age older than 18 years with recurrent or progressive TIA or infarction despite optimal medical therapy, including anti-coagulation, dual anti-platelet, and anti-lipid medication; 2) previous ischemic events or asymptomatic severe stenosis (more than 50%) with poor collateral cerebral circulation, or diminished cerebral perfusion on single photon emission computed tomography before and after administration of the intravenous dosage of acetazolamide. RESULTS: The median age of patients was 53 years (range 44-79). The technical success rate was 100%. Mean pretreatment stenosis degree was 83.63 +/- 9.53% and 29.1 +/- 15.4% before and after angioplasty, respectively. Procedural-related complications occurred in four of 11 patients (36%), but none of the patients had permanent neurological deficit. All patients were available for an average follow-up period of 19.4 +/- 5.1 months. One patient had a stroke in the territory of angioplasty at two months after angioplasty. The stroke free survival rate at 30 days and 12 months was 100% and 91%, respectively. Restenosis over 50% was observed in three of 11 patients (27%); all were asymptomatic. CONCLUSION: Intracranial angioplasty for symptomatic MCA stenosis refractory to medical therapy can be a treatment option to reduce the risk of further TIA or stroke.

The abdominal tumors in children are different from those of adult. These tumors are the third most common one, preceded by leukemia and brain tumors, in children under 15 years. X-ray examination is the most important method among diagnostic approaches. The role of diagnostic imaging is to identify the precise anatomic location and extent of pathologic process with the minimal number of imaging procedures. 23 cases of abdominal tumors were reviewed in respect of age incidence, site of origin, radiologic findings. The results are briefly summarized as follows: 1. Neuroblastoma was the most common (6 cases) and wilm's tumor (5 cases), choledocal cyst (4 cases), ovarian mass (3 cases), hydronephrosis (2 cases), were descending order in frequency. 2. The most common site was retroperitoneum (60%) Kidney was the single most common site of origin. 3. Radiologic findings. The most common findings of plain radiography was ill defined soft tissue mass and this method was helpful in the presence of calcification especially in neuroblastoma. Ultrasonographic pattern was anechoic (cystic), echoic or mixed pattern, but this method provide less precise anatomical details, nevertheless Ultrasonography was particularly useful imaging modality for the pediatric abdominal tumors. IVP findings were renal displacement, caliceopelvic system distortion or nonvisualization of kidney, these information was helpful in determining the location of tumors. CT scan showed homogenous or inhomogeneous, cystic or solid, mass with their anatomic location. 4. Ultrasonography was the most widely used specific diagnostic method, but had limited value in detecting the anatomic location of tumors. CT scan was superior to ultrasound for determining the extent of tumors.

PURPOSE: We expected the motion fraction could be checked, with simple radiographic examination, according to the guide-line of fluoroscopic technique, and recovery of the function also could be correlated with the improvement of the motion fraction. MATERIALS AND METHODS: We measured the motion fraction of the glenohumeral and scapulothoracic movement using fluoroscope in 30-degree intervals of arm elevation in the scapular plane. The ratio of glenohumeral to scapulothoracic movement (thetaGH/thetaST) was 1.6 for the full range of motion in scapular plane. During arm elevation, scapular tilting from the coronal plane was decreased from 42 degrees to 20 degrees tilting as well as internal rotation (scapular extension). We also measured the motion fraction (thetaGH/thetaST) and functional recovery of the shoulder in 11 patients after operative treatment of the shoulder instability in 15 patients from December 1996 to August 1997. RESULTS: We could find out a significant correlation between the recovery of motion fraction and shoulder function. These results would be applied in planing rehabilitation program after treatment of the shoulder instability. CONCLUSIONS: The measuring technique of glenohumeral to scapulothoracic movement (thetaGH/thetaST) with fluoroscopy could be applied to the simple radiographic measurement at the out-patient clinic in order to identify the pathology and recovery of shoulder motion after treatment

BACKGROUND: Decreased activities of daily living (ADL) in elderly people are related to decreased quality of life and death and are a clinically important issue. However, few studies have investigated the various characteristics and risk factors for a decline in ADL among elderly in-patients in geriatric hospitals in Korea. METHODS: In total, 163 elderly in-patients with dementia in three geriatric hospitals located in Incheon, Gwangju and Yongin, Korea were surveyed prospectively for associated factors of a decline in ADL after 6 months. RESULTS: On average, the subjects were 79.4+/-7.6 years old, and 67.5% were female. Approximately 63% had Alzheimer type dementia, 36.8% only attended primary school, 73.0% were widowed, and 38.7% had been admitted to hospitals for less than 1 year. The Korean version of the Mini Mental State Examination (K-MMSE) score was 14.1+/-6.5, and the clinical dementia rating was 1.9+/-0.9. In total, 8.6% were bed-ridden and 59.5% and 64.6% had never experienced fecal and urinary incontinence, respectively. Total ADL scores declined after 6 months follow-up, and significantly associated factors were low K-MMSE score, fecal incontinence, and co-existence of fecal and urinary incontinence. CONCLUSION: Low K-MMSE scores, fecal incontinence, and the co-existence of fecal and urinary incontinence were associated with ADL declines in elderly in-patients with dementia in long-term care hospitals located in three cities in Korea.

PURPOSE: High-grade (III, IV, V) renal injury may need interventional management. We investigated whether the selective embolization of the renal artery is effective for the treatment of major renal injury in comparison with emergency renal exploration. METHODS: We retrospectively reviewed the medical and radiologic records of patients who underwent surgery or embolization for renal injury (Grade III, IV, V) between January 1990 and December 2007. We analyzed the change in treatment method before and after 2000, the blood pressure, the hemoglobin at the time of visit, the hospital days and the complications in patients who received surgery or embolization. Preserved renal functions of the embolized kidneys were identified by using enhanced CT. RESULTS: Cases of surgery and embolization were 37 and 13, respectively: 5 and 4 in renal injury grade III, 17 and 6 in grade IV and 13 and 3 in grade V. Cases of surgery and embolization were 33 and 1 before 2000 and 2 and 12 after 2000, repectively: embolizations increased after 2000. No significant differences in mean diastolic pressure, hemoglobin, hospital days and complications existed between the surgery and the embolization groups (p>0.05). However, the transfusion volume was significantly smaller in the embolization group (p<0.05). One postoperative complication occurred in the surgery group. We identified the preserved renal functions of the embolized kidney by using enhanced CT. CONCLUSION: Embolization could be one treatment method for high-grade renal injury. Thus, we might suggest selective embolization a useful method for preserving the renal function in cases of high-grade renal injury.
