Abstract
OBJECTIVE Most cutaneous squamous cell carcinomas (cSCC) are low risk and can be treated with simple excision or ablation. High-risk cSCC require invasive treatment, including radical surgery. We present our experience in treating invasive cSCC of the pelvis and extremities. METHOD A retrospective review of the data of patients with invasive cSCC, indicated for surgery between 2014 and 2018, from a single institution was carried out. RESULTS A total of 19 patients (nine men, 10 women) were included in the study. Mean age was 62 years; mean tumour size was 8.6cm). Of the 19 patients, five patients with paraplegia with cSCC arising from hard-to-heal ulcers died of infection or bleeding after surgery or systemic therapy. Also, nine patients with localised cSCC underwent margin-negative resection with or without radiation; one patient experienced disease relapse. Of the participants, two patients with previous transplants and multifocal aggressive cSCC underwent numerous resections but succumbed to disease, and two patients who presented with locally recurrent disease after previous positive margin resection and radiation underwent re-resection but developed recurrent disease. CONCLUSIONS Prognosis for invasive cSCC largely depends on clinical setting. Tumours arising from ulcers in patients with paraplegia have a poor prognosis regardless of treatment. Invasive cSCC in transplant patients are often multifocal and often recur. Debulking procedures are associated with local recurrence despite radiation. Patients presenting with localised disease have a favourable prognosis with wide resection, flap coverage and adjuvant therapy.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE Facet fusion in minimally invasive spine surgery (MISS) may reduce morbidity and promote long-term construct stability. The study compares the maintenance of correction of thoracolumbar (TL) trauma patients who underwent MISS with facet fusion (FF) and without facet fusion (WOFF) and evaluates instrumentation loosening and failure. METHODS TL trauma patients who underwent MISS between 2006 and 2013 were identified and stratified into FF and WOFF groups. To evaluate progressive kyphosis and loss of correction, Cobb angles were measured at immediate postoperative, short-term, and long-term follow-up. Evidence of >2 mm of radiolucency on radiographs indicated screw loosening. If instrumentation was removed, postremoval kyphosis angle was obtained. RESULTS Of the 80 patients, 24 were in FF and 56 were in WOFF group. Between immediate postoperative and short-term follow-up, kyphosis angle changed by 4.0° (standard error [SE] 1.3°) in the FF and by 3.0° (SE 0.4°) in the WOFF group. The change between immediate postoperative and long-term follow-up kyphosis angles was 3.4° (S.E 1.1°) and 5.2° (S.E 1.6°) degrees in the FF and WOFF groups, respectively. Facet fusion had no impact on the change in kyphosis at short term (P = .49) or long term (P = .39). The screw loosening rate was 20.5% for the 80 patients with short-term follow-up and 68.8% for the 16 patients with long-term follow-up. There was no difference in screw loosening rate. Fifteen patients underwent instrumentation removal-all from the FF group. CONCLUSION FF in MISS does not impact the correction achieved and maintenance of correction in patients with traumatic spine injuries.

Abstract
Purpose To develop and test a computed tomography (CT)-based predictive model for major arterial injury after blunt pelvic ring disruptions that incorporates semiautomated pelvic hematoma volume quantification. Materials and Methods A multivariable logistic regression model was developed in patients with blunt pelvic ring disruptions who underwent arterial phase abdominopelvic CT before angiography from 2008 to 2013. Arterial injury at angiography requiring transarterial embolization (TAE) served as the outcome. Areas under the receiver operating characteristic (ROC) curve (AUCs) for the model and for two trauma radiologists were compared in a validation cohort of 36 patients from 2013 to 2015 by using the Hanley-McNeil method. Hematoma volume cutoffs for predicting the need for TAE and probability cutoffs for the secondary outcome of mortality not resulting from closed head injuries were determined by using ROC analysis. Correlation between hematoma volume and transfusion was assessed by using the Pearson coefficient. Results Independent predictor variables included hematoma volume, intravenous contrast material extravasation, atherosclerosis, rotational instability, and obturator ring fracture. In the validation cohort, the model (AUC, 0.78) had similar performance to reviewers (AUC, 0.69-0.72; P = .40-.80). A hematoma volume cutoff of 433 mL had a positive predictive value of 87%-100% for predicting major arterial injury requiring TAE. Hematoma volumes correlated with units of packed red blood cells transfused (r = 0.34-0.57; P = .0002-.0003). Predicted probabilities of 0.64 or less had a negative predictive value of 100% for excluding mortality not resulting from closed head injuries. Conclusion A logistic regression model incorporating semiautomated hematoma volume segmentation produced objective probability estimates of major arterial injury. Hematoma volumes correlated with 48-hour transfusion requirement, and low predicted probabilities excluded mortality from causes other than closed head injury. © RSNA, 2018 Online supplemental material is available for this article.

Abstract
In 2009 and 2010, approximately 2% of plants had disease symptoms, including initial leaflet chlorosis that later developed into necrotic spots and general necroses along the leaflet. Fruit production on affected plants was substantially reduced and necroses were also present. Total RNA was extracted from five symptomatic plant samples using the RNeasy Plant Mini Kit (Qiagen, Hilden, Germany) and analyzed by reverse transcription (RT)-PCR with specific primer pair: TR2F (5' GAAGGACGAAGAGCGACTG 3'), and TR2R (5' AAGGTAGGTATGCGTTTGC 3') (1). The primers amplified a 575-bp fragment within the coat protein Vp23 of Tomato torrado virus (ToTV). No RT-PCR products were observed when water or asymptomatic tomato plants were used as controls. The RT-PCR products were purified and directly sequenced in both directions. Pair-wise similarity analysis confirmed the presence of ToTV with 99% similarity to isolate PRI-ToTV0301 (GenBank Accession No. DQ388880) and 98% similarity to isolate Kra (Accession No. EU652402). A representative sequence was deposited with GenBank (Accession No. GU903899). To further confirm the presence of ToTV, dsRNA analysis was conducted on all five symptomatic plants and one healthy tomato plant (2). Electrophoresis of dsRNA showed two bands of approximately 5,400 and 7,800 nucleotides long, typical of ToTV in all samples, while a third band between the other two (approximately 6,400 nt) was detected. Serological testing using double-antibody sandwich-ELISA was also conducted on the five symptomatic and 25 additional plants from the same greenhouse that displayed typical Pepino mosaic virus (PepMV) symptoms only. Antibodies used for serological testing screened for the presence of PepMV, Tomato spotted wilt virus, Cucumber mosaic virus, and Tomato mosaic virus (Loewe Biochemica, Sauerlach, Germany). These tests detected PepMV in all samples with disease symptoms typical of PepMV, and in three of the five samples with the newly described symptoms. To our knowledge, this is the first report of ToTV in Italy, and in some plants, co-infection with PepMV was likely. All ToTV-infected tomato plants in the greenhouse were destroyed.

Abstract #3068
Background: BP1 is a member of the homeobox gene family, a highly conserved family of transcription factor genes. pBP1 is a homeotic protein that is upregulated in 80% of invasive ductal breast tumors. We have previously shown that the percentage of pBP1 positive breast cancer cases increases with the extent of cellular proliferation and carcinogenesis. BP1 expression is associated with aggressive tumors: 100% of ER negative tumors were BP1 positive, compared with 73% of ER positive tumors. pBP1 is secreted by MCF-7 cells, T47D cells, and MDA-MB-231 breast cancer cells, but not by MCF10A or H16N2 normal breast epithelial cells. In all cell lines tested, secreted pBP1 is internalized, resulting in stimulation of growth. Moreover, incubation of MCF-7 or MCF10A cells in recombinant pBP1 results in stimulation of several oncogenes, including bcl-2, Twist, and Met. These results led us to ask whether we could abrogate mitogenic stimulation by addition of anti-pBP1 antibody.
 Materials and Methods. Cells were incubated in 10 µg/ml anti-BP1 Ab (Novus) or 10 µg/ml IgG for three days. Growth was measured using MTT assays and apoptosis was assessed by flow cytometry after staining with Annexin V (Trevigen).
 Results. Addition of anti-BP1 Ab to the growth medium of MCF-7 cells, T47D cells, and MDA-MB-231 cells caused significant growth inhibition and apoptosis. In contrast, addition of anti-BP1 Ab to the growth medium of MCF10A and H16N2 cells did not lead to significant growth inhibition or apoptosis.
 Discussion. Our novel finding that pBP1 is secreted by breast cancer cells but not normal breast epithelial cells was the impetus to test the effect of adding anti-BP1 Ab to the growth media of both types of cells. Remarkably, anti-BP1 Ab kills only the breast cancer cells, suggesting they may be BP1-dependent. Our data indicate it may be possible to specifically target BP1 positive breast cancer cells in the 80% of women with BP1 positive tumors.
