PURPOSE: We investigated the optimal orientation of femoral tunnel in PCL reconstruction. MATERIALS AND METHODS: Five cadaver knees were used for this study. We made the tibial tunnel at the center of foot-print of posterior cruciate ligament, at an angle of 45o to the long axis of the tibia using the Kirschner wire. The femoral tunnel was made 11mm posterior to the articular cartilage margin of medial femoral condyle. The orientation of the femoral tunnel was made on the expolated line between two points, namely the placement of the femoral tunnel on lateral wall of medial femoral condyle and the opening of the tibial tunnel in full extension of knee. We measured the angles between the tunnel and wire on roentgenogram which passed through the femoral and tibial tunnel. RESULT: On the anteroposterior view, the angle of the graft to the long axis of the femur became acute during flexion. The angle of the graft to the long axis of the femur on the coronal plane changed from 12.6o to 154.9o with flexion from 0o to 105o. The angle of the graft to the long axis of the femur on sagittal plane changed from 137.0o to 45.1o with flexion from 0o to 105o. These results suggest that optimal graft-tunnel divergence (GTD) is obtained when the angle of graft to the long axis of the femur are 83.8o on the coronal plane and about 91o on the sagittal plane. CONCLUSION: To obtain optimal orientation of the femoral tunnel, the opening of the femoral tunnel should be located as near as possible to the margin of the articular cartilage of the medial femoral condyle.

STUDY DESIGN: Retrospective study. PURPOSE: To investigate the relation between the progression of kyphotic deformity and magnetic resonance imaging (MRI) findings in conservatively treated stable thoracolumbar fractures. OVERVIEW OF LITERATURE: When treated conservatively, excessive progression of kyphotic deformity and vertebral compression can emerge during follow-up. We sought to identify predictors of vertebral body deformation using MR images. METHODS: The presence in MR images of anterior longitudinal ligament (AL) or posterior longitudinal ligament (PL) injury, superior or inferior endplate disruption, superior or inferior disc injury in fractured vertebral bodies, the existence of low signal intensity on T2 weighted images, and bone edema of intravertebral bodies were assessed. RESULTS: The presence of superior endplate disruption and a higher level of bone edema were found to cause the progressions of kyphotic angle (KA), wedge angle (WA), and anterior vertebral compression (AVC) rate. When AL or superior disc injury was observed, only KA increased meaningfully. When low signal intensity was present on T2 weighted images WA and AVC increased significantly, but PL injury, inferior endplate disruption, and inferior disc injury showed no notable correlation with kyphotic deformity progression. The risk factors found to be associated with an increase of KA to >5degrees were AL injury, superior endplate disruption, superior disc injury, and a bone edema level of over 1/3, and their associated risks versus no injury cases were 14.1, 3.7, 6.8, and 10.4-fold, respectively. CONCLUSIONS: AL injury, superior endplate and disc injury, or a high level of bone edema, were critical factors that determine kyphotic deformity progression.

Acute lymphoblastic leukemia (ALL), in general, can be diagnosed by detecting blasts in peripheral blood or bone marrow. Some of the cases of ALL do not show typical leukemic features, and only manifest as refractory anemia, thrombocytopenia, myelofibrosis and lymphocytic infiltration into bone marrow. Several months after presentation, they may reveal typical leukemic features and are diagnosed as ALL. This kind of leukemia is called ALL with aleukemic prodrome. Although the incidence of ALL with aleukemic prodrome is 1.5~2.2% of childhood ALL cases, it is rarely reported in Korea. We experienced a 6 month-old female infant who presented with refactory anemia and thrombocytopenia, and two serial of bone marrow examination revealed only myelofibrosis. She subsequently developed ALL 3 months later. We report this case with a brief review of related literatures.

In patients with situs inversus totalis, the superior vena cava is normally positioned on the left side and drains into a left-sided right atrium (RA). If right-side superior vena cava (RSVC) is also present, it should be thought of as a combined congenital anomaly. Here, we report a case of successful pacemaker lead insertion through the RSVC in a patient with situs inversus totalis. The left-side superior vena cava (LSVC) had been already used as a route for the first pacemaker lead insertion 15 years earlier. During the pacemaker lead revision, we found that the LSVC was obliterated, and used the RSVC as a route for a new pacemaker lead insertion.

Malignant tumors have been shown to be a major secondary cause of nephrotic syndrome. They have been associated with different glomerulopathy depending on their type. Membranoproliferative glomerulonephritis (MPGN) rarely develops in solid tumors, although cases have been reported in renal cell cancer, melanoma, lung cancer, and tumors in the urogenital system. However, to our knowledge, there have been no case reported of MPGN associated with thyroid cancer. In the present case, we observed MPGN associated with thyroid cancer in a 44-year-old woman with nephrotic syndrome and renal insufficiency. Her thyroid ultrasound revealed a tumor measuring 1.01x1.14x1.48 cm with an indistinct border that was partially calcified. The tumor was confirmed to be papillary carcinoma by percutaneous needle aspiration biopsy. Renal biopsy showed chronic tubulointerstitial nephritis and MPGN. On day 45 of admission, total thyroidectomy and neck lymphadenectomy were performed. After total thyroidectomy, serum total protein, albumin, C3, and C4 normalized. In conclusion, this case represents the first report of simultaneous development of MPGN and thyroid cancer.

OBJECTIVE: To investigate the association between bone mineral density (BMD) and osteoporotic compression fractures in radiographic spinal osteoarthritis (OA) patients. METHODS: Subjects were 382 female patients (ages 45 to 85) from outpatient clinic for osteoporosis and rheumatic diseases. BMD was measured at lumbar spine and hip by dual X-ray absorptiometry (Hologic QDR 2000). The standard anteroposterior and lateral plain radiographs of thoracic and lumbar spine were taken to define spinal OA and vertebral compression fractures. Radiographic spinal OA was defined by grade of disc degeneration and facet joint degeneration. Frequency of vertebral fractures was compared between spinal OA and control patients in relation to their BMD, age, weight, body mass index (BMI) and years post menopause. RESULTS: Higher proportion of fracture cases were observed in spinal OA patients than non-spinal OA patients (34.1%, 44/129 vs. 18.2%, 46/253, p<0.001) despite comparable mean BMD (0.836+/-0.152 vs. 0.834+/-0.185, p=0.89) and older mean age (65.8+/-8.5 vs. 57.8+/-10.3, p<0.001). In subjects of ages from 65 to 74, spinal OA patients showed significantly higher BMD than non-spinal OA patients (0.784+/-0.125 vs. 0.719+/-0.119, p=0.007), but the frequency of fractures seems to be higher than that of non-spinal OA patients (44.9%, 22/50 patients vs. 34%,19/55 patients, p=0.58). When all study subjects were stratified according to their spine BMD (normal, osteopenia, and osteoporosis), significantly higher proportion of vertebral compression fractures was noted in spinal OA than non-spinal OA patients in osteopenia group (38.5% vs. 13.5%, p<0.001). CONCLUSION: Higher BMD does not seem to be translated directly into decreased risk of osteoporotic compression fractures in spinal OA patients. Careful assessment of risk factors for osteoporotic fractures and newer methods for assessing bone strength in this group of patients are needed.

Five monoclonal antibodies (MAbs) and chicken immunoglobulin (IgY) were developed by immunizing with flagella purified from Listeria monocytogenes 4b and the five MAbs have been confirmed to be specific against three different epitopes of flagellin. The antibodies showed specific reaction to Listeria genus and no cross-reactivity with other bacteria tested in this experiment including E.coli O157:H7 and Salmonella enteritidis. Sandwich enzyme-linked immunosorbent assays (ELISA) using the MAbs and IgY were developed to detect Listeria species and the sensitivity and specificity of the developed ELISA have been analyzed. The detection limit of ELISA using MAb 2B1 and HRP labeled IgY was 1 x105cells/0.1 ml at 22degrees C and 1x106 cells/0.1 ml at 30degrees C. ELISA using the pair of MAbs (MAbs 2B1 and HRP labeled MAbs 7A3) detected up to 104cells/0.1 ml at 22degrees C and 30degrees C. Detection limit of sandwich ELISA using IgY was 10 times lower than MAb pair. Using the developed ELISA, we could detect several Listeria contaminated in food samples after 48 h-culturing. In conclusion, both MAbs and IgY have been proved to be highly specific to detect Listeria flagella and the developed sandwich ELISA using these antibodies would be useful tool for screening Listeria spp. in food.
