STUDY DESIGN: Retrospective study OBJECTIVES: The purpose of this study was to analyze patients who developed deep wound infections after receiving PLIF for degenerative lumbar disease, and report the treatment outcomes. SUMMARY OF LITERATURE REVIEW: Few studies have examined deep wound infections after PLIF, and there is some controversy regarding whether screws or cages need to be removed to treat infections. MATERIALS AND METHODS: Nine cases(spinal stenosis 6, spondylolisthesis 3) developed a deep wound infection after PLIF from 2001 to 2007. The mean follow up was 48 months (24-72). The clinical results were evaluated using MacNab's criteria. RESULTS: The diagnosis of infection was made based on the clinical symptoms and signs, and inflammatory markers, such as ESR and CRP. The time to diagnosis was less than one week (2), three weeks (2), six weeks (1) and three months or more (4). Bacterial identification was performed on seven cases. MRSA was detected in one of them, and no bacteria were identified in the other six. In two of them, the infection subsided with antibiotic therapy only. In 7 cases, removal of the cage and anterior iliac strut graft was needed for infection control. In four cases, loosened screws were removed during debridement. In 2 cases, additional surgery for pseudarthrosis was required after curing the infection. CONCLUSIONS: In deep infections after PLIF, early diagnosis and bacterial identification are important for reducing the need for a later radical operation. It is recommended that blood markers of infection be measured with a short follow-up period. In a case of persistent infection against prolonged antibiotics, removal of the cage or screw is needed to treat the infection earlier.

PURPOSE: This study was attempted to investigate the prevalence of the expression of c-fos protein, TGF-alpha and -beta, PCNA , DNA ploidy pattern and histopathological parameters of giant cell tumor (GCT) of bone and to correlate with prognosis and to extend our understanding on tumorigenesis of GCT. MATERIALS AND METHODS: Twenty eight cases of paraffin-embedded tissue were studied, classified as recurrent (5 cases) and non-recurrent group (12cases) within the limits of the cases which afforded surgical material on first operation. RESULTS: No significant difference was observed in cellularity of stromal cells, atypia of stromal and giant cells, presence of hemorrhage and necrosis between recurrent and non-recurrent group. However, presence of more than 10 mitotic figures in 10 high power fields in recurrent group was significantly higher than non-recurrent group (p<0.05). The immunoreactivity for PCNA was seen only in nuclei of stromal cells, whereas nuclei of giant cells showed negative staining. The positivity of PCNA revealed no significant difference between non-recurrent (mean; 40.9%) and recurrent group (34.4%). The expression of c-fos oncogene was seen in 5 cases (100%) in recurrent group, and 8 cases (66.7%) in non-recurrent group, and no significant difference was seen. No significant difference of expression of TGF-alpha was seen in 5 cases (100%) in recurrent group and in 11 cases (91.7%) in non-recurrent group. The expression of TGF-beta in stromal cells was significantly higher in non-recurrent group (80%) compared to recurrent group (100%) (p<0.05). In DNA analysis out of 18 cases, 4 cases (22.2%) were aneuploidy and 14 cases (77.8%) were diploidy. Among 4 aneuploidy cases, 3 cases (75%) had no recurrence, and 1 case (25%) had metastasis to lung and expired. No significant difference of DNA ploidy pattern was seen between the recurrent and non-recurrent group. CONCLUSION: Presence of more than 10 mitotic figures in 10 high power fields and less expression of TGF-beta are related to higher possibility of recurrence and it is suggested that the number of mitotic figure (more than 10/10HPF) and expression of TGF-beta could be helpful parameters in predicting recurrence of GCT.

PURPOSE: The purpose of this study was to investigate the diametral tensile strength of polymer-based temporary crown and fixed partial denture (FPD) materials, and the change of the diametral tensile strength with time. MATERIAL AND METHODS: One monomethacrylate-based temporary crown and FPD material (Trim) and three dimethacrylate-based ones (Protemp 3 Garant, Temphase, Luxtemp) were investigated. 20 specimens (the empty set 4 mm x 6 mm) were fabricated and randomly divided into two groups (Group I: Immediately, Group II: 1 hour) according to the measurement time after completion of mixing. Universal Testing Machine was used to load the specimens at a cross-head speed of 0.5 mm/min. The data were analyzed using one-way ANOVA, the multiple comparison Scheffe test and independent sample t test (alpha = 0.05). RESULTS: Trim showed severe permanent deformation without an obvious fracture during loading at both times. There were statistically significant differences among the dimethacrylate-based materials. The dimethacrylate-based materials presented an increase in strength from 5 minutes to 1 hour and were as follows: Protemp 3 Garant (23.16 - 37.6 MPa), Temphase (22.27 - 28.08 MPa), Luxatemp (14.46 - 20.59 MPa). Protemp 3 Garant showed the highest value. CONCLUSION: The dimethacrylate-based temporary materials tested were stronger in diametral tensile strength than the monomethacrylate-based one. The diametral tensile strength of the materials investigated increased with time.

Of 35 patients with 38 knees treated using simple excision method for Osgood-Schlatter lesion, had a distinct and separate ossicle at the tibial tubercle. All ossicles were attached to the distal part of the undersurface of the ligamentum patellae and were separated from the tuberosity by a bursa or scar tissue. Surgical excision of ossicle along with adjacent bursa was satisfactory and simplest procedure to relieve the symptoms, did not respond to conservative treatment.
