Osteoporosis causes a decrease in bone mineral density. To overcome the decrease in fixation strength, a variety of techniques and devices have been developed, including cement augmentation of pedicle screws. Polymethyl methacrylate (PMMA), is commonly known as bone cement, and is widely used for implant fixation in various orthopaedic and spine surgery. In general, PMMA augmentation of pedicle screws is simple and safe if performed with technical precautions. PMMA is a safe agent, but it may rarely lead to significant foreign body reactions. In this report, we present a patient who developed bone cement-related epidural space foreign body granuloma

BACKGROUND: Intermittent rhythmic delta activity (IRDA) is classified as a nonspecific abnormal EEG pattern. IRDA is clinically associated with alteration of consciousness, hydrocephalus, cerebral edema, deep midline lesions, subcortical lesions, and tumors of the posterior fossa and the third ventricle. Frontal IRDA(FIRDA) is usually seen in patients over age 15 years, whereas occipital IRDA(OIRDA) occurs mainly in children. We have investigated the clinical feature and significance of IRDA in children. SUBJECTS AND METHODS: We retrospectively reviewed the medical records of 36 children with IRDA of EEG concerning diagnosis, neurologic examination, classification of epilepsy, and CT & MRI findings. RESULTS: 1) The location of the IRDA was frontal(FIRDA) in 11 of 36(30.5%), occipital(OIRDA) in 20 of 36(55.6%) and mixed in 5 of 36(13.9%) patients. 2) Thirty of 36(83.3%) have epilepsy (including 1 each with MELAS and tuberous sclerosis), 4 of 36(11.1%) have migraine and 2 of 36(11.1%) patients have meningitis. 3) Sixteen of 30(53.3%) have partial or partial with secondary generalized seizure, 10 of 30(33.3%) have generalized seizure and 4 of 30(13.3%) patients with epilepsy have absence seizure. 4) Neuroimaging studies (CT or MRI scan) were performed in 27 cases. Among 27 cases of studies, 6 cases(22.2%) were abnormal including; two cases of infections, and each case of infarction, venous angioma, arachnoid cyst, cortical atrophy, and tuberous sclerosis, respectively. CONCLUSIONS: IRDA may be considered an epileptiform pattern in childhood and FIRDA is frequently seen in children than previous reports.

OBJECTIVE: The purpose of this study was to evaluate the effects of malocclusion on the self-esteem of female university students. METHODS: The subjects were composed of 67 female university students who showed Class I molar relation, no missing or supernumerary teeth and has had no orthodontic treatment experience. Each subject was evaluated with Rosenberg's Self-esteem Scale to measure the level of self-esteem and also evaluated the degree of anterior crowding and lip protrusion through model analysis and cephalometric soft tissue profile analysis. RESULTS: The results showed that a protrusive profile and crowding of upper anterior teeth had significant reducing effects on the level of self-esteem. The protrusion and crowding groups showed no significant differences in self-esteem between groups. CONCLUSIONS: Malocclusion had significant negative effects on the self-esteem of female university students. Further research to investigate the negative psychological influence of malocclusion and the education of lay people about this influence is necessary.

STUDY DESIGN: Retrospective study OBJECTIVE: To analyze the treatment results of vertebroplasty in patients who suffered osteoporotic compression fractures during conservative treatments for pre-existing degenerative lumbar disease. SUMMARY AND LITERATURE REVIEW: Whilst spinal fusion has shown satisfactory clinical results, solid fusion has been reported to accelerate the degenerative changes at the unfused adjacent levels. Therefore, the level of spinal fusion in patients with compression fractures and pre-existing degenerative lumbar disease is controversial. Few studies have evaluated the outcomes of spinal fusion and adjacent segment vertebroplasty. MATERIALS AND METHODS: A retrospective review was carried out on 28 patients who suffered the osteoporotic compression fractures during conservative treatment for pre-existing degenerative lumbar disease. Posterolateral fusion and vertebroplasty were performed for degenerative disease and compression fractures. The average fusion level was 1.82. The mean compressed vertebral bodies were 1.68. The radiology results were evaluated to determine the progression of the compression rate and fractures in the adjacent segment. The clinical results were evaluated using the Denis pain scale for compression fractures and Katz satisfaction scale for degenerative lumbar disease. RESULTS: The average compression rate was 30.2% preoperatively, 21.4% postoperatively, and 24.6% at the final follow-up. There was no fracture in the adjacent segment. Clinically, the preoperative Denis score was P3 and P4 in 8 and 20 patients, respectively. On the other hand, the postoperative Denis score was P1, P2 and P3 in 8, 19 and 1 patients, respectively. In regard to degenerative diseases, the overall satisfaction was 82.1%. CONCLUSION: The stability of fracture sites in vertebroplasty of patients with pre-existing lumbar disease was confirmed. However, further compression of the fractured vertebral body was observed after vertebroplasty in long fusion. Therefore, a followup study of more cases will be necessary to confirm the changes in the vertebroplasty site.

Two cases of abnormalities of the left ventricular wall(left ventricular aneurysm or diverticulum) are presented. A saccular deformity of the left ventricle may be and aneurysm or a diverticulum. In one case, the defect seems to be subcalvular aneurysm(or fibrous diverticulum) or aneurysm of the membranous ventricular septum; this lesion seems to be a natural consequence of spontaneous closure of a defect of the membranous septum. The other case, it seems that the defect is ventricular aneurysm with syndrome of myocardial infarction and normal coronary arteries, or double or accessory chambered left ventricle. The thromboembolic phenomenon was noted on a left frontoparietal lobe of brain. Both cases have the diagnosis supported by cardiac catheterization and angiography. The clinical, angiographic and pathologic characteristic of diverticulum and aneurysm of the heart are reviewed, and an attempt is made to clarify the concept of aneurysm and diverticulum of the heart.

PURPOSE: To analyze minimum 2-year clinical and radiological follow-up results of primary total knee replacement arthroplasty (TKRA) with metal block augmentation for tibial bony defect. MATERIALS AND METHODS: We analyzed 67 cases (52 patients) of primary TKRA with metal block augmentation for tibial bony defects from March 1999 and March 2008. Clinical results were evaluated using the Knee Society clinical rating system and the Western Ontario and McMaster University (WOMAC) score. Radiologic results were evaluated using the Knee Society roentgenographic evaluation system. RESULTS: The mean knee score and function score improved from 42.0 and 45.6 preoperatively to 94.5 and 85.4 postoperatively. At last follow-up, the mean WOMAC score was 16.8. The incidence of radiolucent lines was 10% (7 cases) during the follow-up period, but there was no case of progression. There were no statistically significant differences between the groups divided according to the block size (below 5 mm and over 8 mm) and between the stem and no-stem groups for all parameters. CONCLUSIONS: Primary TKRA with a metal block produced satisfactory results for the minimum 2-year follow-up and can be considered as a simple and effective method for the treatment of tibial bony defect in primary TKRA.

PURPOSE: The purpose of this study was to compare the clinical results between patellar resurfacing and patellar retention during total knee arthroplasties (TKA) in both sides of the knee from one patient. MATERIALS AND METHODS: A prospective randomized study was performed for 18 patients, who underwent only unilateral patellar resurfacing without any consideration for the condition of the patella cartilage, among the patients who had osteoarthritis and who underwent bilateral TKA from February 2004 to February 2008. The clinical results were compared using the American Knee Society clinical rating system, Feller's patellar score and the Kujala scoring system. RESULTS: The mean of the knee score and the function score were 94.3 and 73.7 postoperatively in the resurfaced patellar side and these values were 91.4 and 73.6, respectively, in the unresurfaced patella side (p=0.07, p=1.00). The Feller's patella scores were 26.5 and 25.3 for each side (p=0.219). The Kujala scores were 71.7 and 69.9, respectively (p=0.086). There was no statistically significant difference between both sides of the knee for all the parameters. CONCLUSION: There were no statistically significant differences between the resurfaced and non-resurfaced knees with comparing them according to the American Knee Society clinical rating system and the patellar evaluation systems. However, further studies are needed to observe whether these results are maintained in the long-term.
