Purpose
Radiological measurement has been accepted as the gold standard for evaluating scoliosis for many years. However, exposure of children to X-ray constitutes a major limitation of the radiological methods. Spinal Mouse (SM) is a safe, practical and easy to perform measurement of curvature in scoliosis, but its validity and reliability have not been investigated. The aim of this study was to investigate the validity and reliability of Cobb angle and SM measurements in children with adolescent idiopathic scoliosis (AIS).Methods
Fifty-one patients with AIS who were followed up conservatively were included in the study. The mean age of the patients was 14.4 years (9–18 years). Frontal plane curvatures were evaluated with SM by 2 physiotherapists and the results were compared with radiological measurements. Radiological measurements were performed by 2 orthopedists.Results
All the measurements were of the thoraco-lumbar curve and the mean value was 35.08° according to Cobb angle measurement. There was no difference between the interobserver measurements of SM (p = 0.256) while the Cobb degrees measured by the 2 orthopedists was different (p = 0.0001). We did not find a statistically significant difference between Cobb measurements and the SM measurements of observer 1 and 2 (p = 0.505). The interobserver and intraobserver agreement of the Cobb and SM measurements was excellent (ICC = 0.872–0.962). When the differences between the evaluations were compared, the interobserver SM differences were seen to be lower than the interobserver Cobb angle differences (p = 0.003). The agreement between the Cobb and SM measurements was higher for curves over 40°. We found a strong or very strong relationship between measurements made with the Cobb and SM methods (p < 0.0001).Conclusions
We conclude that SM can be used for research and patient follow-up in the clinic as a safe, reliable, quick, and easy to use method with no side effects although it cannot be the only factor to consider when determining the treatment plan of AIS patients.2.
Purpose
Insulin-like growth factor 1 (IGF1) gene single nucleotide polymorphism (rs5742612) has been associated with adolescent idiopathic scoliosis (AIS) in several studies with limited sample size and inconsistent outcomes. So we perform this meta-analysis to assess the precise association between IGF1 gene single nucleotide polymorphism (rs5742612) and AIS.Methods
We systematically searched Pubmed, Embase, Web of Science and Cochrane Library up to January 19, 2016 to obtain relevant studies using our research strategy. Four articles all belonging to case–control studies were included in our meta-analysis.Results
A total of four studies containing 763 cases and 559 controls satisfied the inclusion criteria after judgment by two reviewers. No significant associations were detected between IGF1 gene single nucleotide polymorphism (rs5742612) and AIS (T vs. C, OR = 1.10, 95 % CI 0.91–1.34, p = 0.32; TT vs. CC: OR = 1.28, 95 % CI 0.82–2.02, p = 0.28; TC vs. CC: OR = 1.29, 95 % CI 0.82–2.06, p = 0.27; TT/TC vs. CC: OR = 1.28, 95 % CI 0.83–1.98, p = 0.27; TT vs. TC/CC: OR = 1.06, 95 % CI 0.82–1.36, p = 0.66).Conclusions
IGF1 gene single nucleotide polymorphism (rs5742612) is not significant associated with susceptibility to AIS in either Asian or Caucasian populations. However, IGF1 gene rs5742612 may be associated with severity of AIS. Further studies with larger sample size and different population groups involving the relationship are required to confirm the potential association.3.

Purpose
In the last few years several reports stressed the importance of sagittal alignment in adolescent idiopathic scoliosis (AIS) patients. It was recently reported that T1 slope, defined as the angle between the superior endplate of T1 and the horizontal, correlates strongly with overall sagittal parameters. The aim of this study was to assess the impact of T1 parameters (T1-slope and T1-tilt) on sagittal alignment of AIS hypokyphotic patients preoperatively and postoperatively.Methods
Twenty-nine AIS patients with <20° preoperative hypokyphosis were included in a retrospective study. Surgery systematically comprised hybrid construct with screws below T11, sublaminar bands at thoracic level and a lamino-laminar claw on the upper instrumented vertebra. Preoperative, postoperative and 2-year follow-up radiological assessment included Cobb angle, T1 slope, T1 sagittal tilt, regional sagittal parameters and pelvic parameters.Results
In the series as a whole, coronal Cobb angle was significantly reduced postoperatively (58° vs. 17°; p < 0.001), thoracic kyphosis significantly improved (12.4° vs. 25.6°; p < 0.001) and cervical lordosis significantly restored (6.2° kyphosis vs. 4.1° lordosis; p < 0.001). There was a significant modification in T1-slope (10.2° vs. 18.2°; p < 0.001). Preoperatively, T1 slope was significantly correlated with T1 tilt (r = 0.427; p = 0.029). Postoperatively, T1 slope was significantly correlated with T1 tilt (r = 0.549; p = 0.002), thoracic kyphosis (r = 0.535, p = 0.005) and cervical lordosis (r = ?0.444, p = 0.03). Restoration of cervical lordosis was significantly correlated to changes of T1-slope (r = ?0.393, p = 0.032), which was significantly correlated to postoperative thoracic kyphosis.Conclusion
According to these results, T1 seems to be of major interest in postoperative modifications of sagittal alignment. T1 slope and sagittal tilt are good indicators of postoperative changes for regional (cervical lordosis and thoracic kyphosis) and global parameters. We therefore consider these parameters as essential in the assessment of AIS patients. Further studies and correlation with clinical scores will, however, be necessary in order to confirm the present findings.4.

Purpose
Global DNA hypomethylation plays an important role in genomic instability and carcinogenesis. The long interspersed nucleotide element-1 (LINE-1) methylation level is a good surrogate marker of the global DNA methylation level. Previously, we demonstrated a strong relationship between LINE-1 hypomethylation and poor prognosis in certain cancers. However, the relationship between the LINE-1 methylation level and the clinical outcome of pancreatic cancer (PC) remains unclear.Methods
We used a pyrosequencing assay to measure LINE-1 methylation levels in 126 samples of resected PC and evaluated the prognostic value of the LINE-1 methylation level.Results
LINE-1 methylation levels were significantly lower in PC tissues than in matched noncancerous pancreatic tissues (p = 0.039, n = 36). The tumoral LINE-1 methylation range was 41.3–92.8 (n = 126, mean 77.7, median 78.5, standard deviation 5.7). The LINE-1 methylation level was unrelated to clinical and pathological features. Moreover, LINE-1 hypomethylation was not significantly associated with overall survival, cancer specific survival, or disease-free survival (log-rank p = 0.30, p = 0.18 and p = 0.50, respectively).Conclusion
The LINE-1 methylation level appears not to be associated with poor prognosis in PC. The effect of the LINE-1 methylation level on the survival of PC patients needs to be confirmed in a larger-cohort study.5.
Purpose
Preoperative directionality of shoulder tilting seems to be independent of the radiographic features of proximal thoracic (PT) curve in adolescent idiopathic scoliosis (AIS) patients. To date, no study had investigated the mechanisms underlying the variety of preoperative directionalities of shoulder tilting in AIS patients. The purpose of this study was to evaluate the differences of radiographic features between Lenke type 2 (double thoracic curve) AIS patients with different preoperative directionalities of shoulder tilting.Methods
A total of 130 Lenke type 2 AIS patients were included in this study and were divided into two groups according to the value of radiographic shoulder height (RSH). There were 78 cases (71 females and 7 males) with RSH less than 0 cm in Group A and 52 cases (44 females and 8 males) with RSH equal to or more than 0 cm in Group B. Preoperative standing anteroposterior X-ray films of the spine were obtained in all these subjects and were analyzed with respect to the following parameters: T1 tilt, PT Cobb angle, main thoracic (MT) Cobb angle, the apical level of PT curve, the apical level of MT curve, and RSH. These parameters were compared between these two groups and the correlations between RSH and the other parameters were analyzed in all of these subjects.Results
No significant difference was found between these two groups with respect to PT Cobb angle or the apical level of PT curve (P > 0.05). The apical level of MT curve was significantly more proximal in Group A compared with Group B (P < 0.05). The MT Cobb angle was significantly larger in Group A compared with Group B (P < 0.05). Both the T1 tilt and the PT Cobb angle/MT Cobb angle ratio in Group A were significantly smaller than those in Group B (P < 0.05). The RSH was positively associated with T1 tilt, the apical level of MT curve, and the PT Cobb angle/MT Cobb angle ratio, but was negatively associated with MT Cobb angle (P < 0.05).Conclusion
The directionality of shoulder tilting is diverse in Lenke type 2 AIS patients. The preoperative directionality of shoulder mainly depends on the profile of MT curve rather than that of PT curve. The RSH should be carefully evaluated before making a surgical plan in these patients.6.

Purpose
To examine whether the sacro-femoral-pubic (SFP) angle could estimate pelvic tilt (PT) in scoliotic and normal subjects.Methods
One hundred nine subjects including 38 patients with adolescent idiopathic scoliosis (AIS), 35 patients with congenital scoliosis (CS), and 36 healthy individuals were studied. PT, as the angle between the lines connecting the midpoint of the sacral plate to the centroid of one acetabulum and the vertical plane, and the SFP angle, as the angle between the midpoint of the upper sacral endplate, the centroid of one acetabulum, and the upper midpoint of the pubic symphysis, were calculated on full-length lateral and anteroposterior radiographs, respectively. Correlations between PT and the SFP angle were investigated in each group.Results
The three groups were comparable in terms of age, sex, and the mean SFP angle. The mean PT, however, was significantly lower in healthy subjects compared to that in patients with AIS and CS. Significant and reverse correlations were present between PT and the SFP angle in all three groups (AIS: r = ?0.32, p = 0.04, PT = 82.5???average SFP angle; CS: r = ?0.48, p = 0.003, PT = 95.41???average SFP angle; healthy: r = ?0.33, p = 0.04, PT = 88.95???average SFP angle).Conclusions
Unlike two previous reports, the SFP angle correlated poorly to PT in this study, limiting its use as a suitable surrogate for PT in scoliotic and healthy subjects.7.

Purpose
Variation in rib numbering has been noted in adolescent idiopathic scoliosis (AIS), but its effect on the reporting of fusion levels has not been studied. We hypothesized that vertebral numbering variations can lead to differing documentation of fusion levels.Methods
We examined the radiographs of 161 surgical AIS patients and 179 control patients without scoliosis. For AIS patients, the operative report of fusion levels was compared to conventional vertebral labeling from the first thoracic level and proceeding caudal. We defined normal counts as 12 thoracic (rib-bearing) and five lumbar (non-rib-bearing) vertebrae. We compared our counts with data from 181 anatomic specimens.Results
Among AIS patients, 22 (14 %) had an abnormal number of ribs and 29 (18 %) had either abnormal rib or lumbar count. In 12/29 (41 %) patients, the operative report differed from conventional labeling by one level, versus 3/132 (2 %) patients with normal numbering (p < 0.001). However, there were no cases seen of wrong fusion levels based on curve pattern. Among controls, 11 % had abnormal rib count (p = 0.41) compared to the rate in AIS. Anatomic specimen data did not differ in abnormal rib count (p = 1.0) or thoracolumbar pattern (p = 0.59).Conclusions
The rate of numerical variations in the thoracolumbar vertebrae of AIS patients is equivalent to that in the general population. When variations in rib count are present, differences in numbering levels can occur. In the treatment of scoliosis, no wrong fusion levels were noted. However, for both scoliosis patients and the general population, we suggest adherence to conventional labeling to enhance clarity.8.

Objectives
To investigate the epidemiology of radiographic degenerative lumbar scoliosis (DLS) and symptomatic DLS and clarify the impact of radiographic spinopelvic parameters on the presence of symptoms and quality of life (QOL) in DLS subjects.Methods
We obtained the age, gender, screening for chronic low back pain (CLBP) and lumbar spinal stenosis (LSS), QOL assessments and X-rays of the thoracolumbar spine from 254 patients from the general population for this study. The prevalence of DLS and symptomatic DLS were estimated and factors associated with symptoms, and the QOL in the DLS subjects was analysed.Results
The prevalence of radiographic and symptomatic DLS was 19.2 and 7.8 %, respectively. A female gender (p = 0.018) and decreased sacral slope (p = 0.025) were associated with the presence of CLBP in the DLS subjects. A higher age was also associated with the presence of LSS in these subjects (p = 0.007), whereas the Cobb angle was found to be close the limit for significance (p = 0.063). The sacro-femoral-pubic angle and Cobb angle correlated with the EuroQol-5 dimensions utility score (r = 0.314, p = 0.014) and EuroQol-visual analogue scale score (r = ?0.291, p = 0.043), respectively. Lumbar lordosis and body mass index correlated with the lumbar function (r = 0.285, p = 0.047) and visual analogue scale for leg pain (r = 0.328, p = 0.022) on the Japanese Orthopaedic Association Back Pain Questionnaire, respectively.Conclusions
The prevalence of radiographic DLS in this study was approximately 20 % and roughly 40 % of the DLS subjects had symptoms. Some spinopelvic parameters may impact the occurrence of symptoms and the QOL in DLS subjects.9.
Purpose
Prehospital endotracheal intubation (ETI) for traumatic brain injury (TBI) is a controversial issue. The aim of this study was to investigate the effect of prehospital ETI in patients with TBI.Methods
Cohort-matched study using the US National Trauma Data Bank (NTDB) 2008–2012. Patients with isolated severe blunt TBI (AIS head ≥3, AIS chest/abdomen <3) and a field GCS ≤8 were extracted from NTDB. A 1:1 matching of patients with and without prehospital ETI was performed. Matching criteria were sex, age, exact field GCS, exact AIS head, field hypotension, field cardiac arrest, and the brain injury type (according PREDOT-code). The matched cohorts were compared with univariable and multivariable regression analysis.Results
A total of 27,714 patients were included. Matching resulted in 8139 cases with and 8139 cases without prehospital ETI. Prehospital ETI was associated with significantly longer scene (median 9 vs. 8 min, p < 0.001) and transport times (median 26 vs. 19 min, p < 0.001), lower Emergency Department (ED) GCS scores (in patients without sedation; mean 3.7 vs. 3.9, p = 0.026), more ventilator days (mean 7.3 vs. 6.9, p = 0.006), longer ICU (median 6.0 vs. 5.0 days, p < 0.001) and total hospital length of stay (median 10.0 vs. 9.0 days, p < 0.001), and higher in-hospital mortality (31.4 vs. 27.5 %, p < 0.001). In regression analysis prehospital ETI was independently associated with lower ED GCS scores (RC ?4.213, CI ?4.562/?3.864, p < 0.001) and higher in-hospital mortality (OR 1.399, CI 1.205/1.624, p < 0.001).Conclusion
In this large cohort-matched analysis, prehospital ETI in patients with isolated severe blunt TBI was independently associated with lower ED GCS scores and higher mortality.10.

Purpose
Although adolescent idiopathic scoliosis (AIS) is known to impact the 3D orientation of the spine and pelvis, the impact of the vertebral position relative to the X-ray scanner on the agreement between 2D and 3D measurements of a curve has not been evaluated. The purpose of this study was to investigate the agreement between 2D and 3D measurements of the scoliotic curve as a function of the 3D spinal parameters in AIS.Methods
Three independent observers measured the thoracic and lumbar Cobb angles, Kyphosis, and lordosis on the posterior–anterior and lateral X-rays of AIS patients. The 3D reconstructions were created from bi-planar X-rays and the 3D spinal parameters were calculated in both radio and patient planes using SterEOS software. The degree of agreement between the 2D and 3D measurements was tested and its relationship with the curve axial rotation was determined.Results
2D and 3D measurements of the sagittal plane spinal parameters were significantly different (p < 0.05). The differences between the 2D and 3D measurements were related to the apical vertebrae rotation, the orientation of the plane of maximum curvature, pelvic axial rotation, and the curve magnitude. Differences between the radio plane and patient plane measurements were related to the pelvic axial rotation, Cobb angles, and apical vertebrae rotation, p < 0.05.Conclusion
Clinically and statistically significant differences were observed between the 2D and 3D measurements of the scoliotic spine. The differences between the 2D and 3D techniques were significant in sagittal plane and were related to the spinal curve and pelvic rotation in transverse plane.11.

Purpose
Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine, with unknown origin. Some studies have noted impaired postural balance in AIS, in particular, difficulty to manage situations with sensory conflict. The motion sickness susceptibility can be secondary to a sensory conflict, for example, between visual and vestibular information. Our hypothesis is: patients with AIS have difficulty in managing situations with sensory conflict and therefore have increased motion sickness susceptibility. The purpose of this study was to evaluate in AIS subjects by evaluating their susceptibility to motion sickness, as compared to a control group.Methods
We conducted an analysis of data on motion sickness susceptibility collected prospectively from 2012, with the B score of motion sickness susceptibility questionnaire. This evaluation was completed for 65 adolescents (age 14.5 ± 1.6 year) with major right thoracic AIS (Cobb = 40.7° ± 13.1°) and 71 matched controls (14.6 ± 1.6 year).Results
Adolescents with major right thoracic AIS were more susceptible to motion sickness (B score = 5.3 ± 5.8) than controls (B score = 3.4 ± 3.7) with significant difference (p = 0.025).Conclusions
We interpret our results suggesting there is difficulty for patients with AIS to manage situations with sensory conflict. Previous studies focusing on situations with sensory conflict in AIS have required sophisticated technology. They are not accessible for routine patient management. Our research shows the same result with simple, non invasive, low-cost and quick method: B score of motion sickness susceptibility questionnaire.12.
Purpose
To compare scoliosis progression in quadriplegic spastic cerebral palsy with and without intrathecal baclofen (ITB) pumps.Methods
A retrospective matched cohort study was conducted. Patients with quadriplegic spastic cerebral palsy, GMFCS level 5, treated with ITB pumps with follow-up >1 year were matched to comparable cases by age and baseline Cobb angle without ITB pumps. Annual and peak coronal curve progression, pelvic obliquity progression and need for spinal fusion were compared.Results
ITB group: 25 patients (9 female), mean age at pump insertion 9.4 and Risser 0.9. Initial Cobb angle 25.6° and pelvic tilt 3.2°. Follow-up 4.3 (1.0–7.8) years. Cobb angle at follow-up 76.1° and pelvic tilt 18.9°. Non-ITB group: 25 patients (14 female), mean age at baseline 9.2 and Risser 1.0. Initial Cobb angle 29.7° and pelvic tilt 7.1°. Follow-up 3.5 (1.0–7.5) years. Cobb angle at follow-up 69.1° and pelvic tilt 21.0°. The two groups were statistically similar for baseline age, Cobb angle and Risser grade. Mean curve progression was 13.6°/year for the ITB group vs 12.6°/year for the non-ITB group (p = 0.39). Peak curve progression was similar between the groups. Pelvic tilt progression was comparable; ITB group 4.5°/year vs non-ITB 4.6°/year (p = 0.97). During follow-up 5 patients in the ITB group and 9 in the non-ITB group required spinal fusion surgery for curve progression (p = 0.35).Conclusions
Patients with quadriplegic spastic cerebral palsy with and without ITB pumps showed significant curve progression over time. ITB pumps do not appear to alter the natural history of curve progression in this population.13.
Purpose
To investigate the outcomes of patients with colorectal cancer and initially unresectable or not optimally resectable liver metastases, who were treated using the liver-first approach in the era of modern chemotherapy in Japan.Methods
We analyzed and compared data retrospectively on patients with asymptomatic resectable colorectal cancer and initially unresectable or not optimally resectable liver metastases, who were treated either using the liver-first approach (n = 12, LF group) or the primary-first approach (n = 13, PF group).Results
Both groups of patients completed their therapeutic plan and there was no mortality. Postoperative morbidity rates after primary resection and hepatectomy, and post-hepatectomy liver failure rate were comparable between the groups (p = 1.00, p = 0.91, and p = 0.55, respectively). Recurrence rates, median recurrence-free survival since the last operation, and 3-year overall survival rates from diagnosis were also comparable between the LF and PF groups (58.3 vs. 61.5 %, p = 0.87; 10.5 vs. 18.6 months, p = 0.57; and 87.5 vs. 82.5 %, p = 0.46, respectively).Conclusions
The liver-first approach may be an appropriate treatment sequence without adversely affecting perioperative or survival outcomes for selected patients.14.
Background
To investigate the prognostic significance of altered breast cancer susceptibility gene 1 (BRCA1) and p53 expression in triple-negative breast cancer (TNBC).Methods
Immunohistochemical expression of BRCA1 and p53 was examined in the tumor tissues of 465 TNBC cases and relations were sought with clinicopathological features and patient survival.Results
Loss of BRCA1 expression was found in 29.5% (137/465) of TNBCs. Positive expression of p53 was observed in 49.9% (232/465). Patients with loss of BRCA1 expression had a tendency to have higher rate of lymph node metastasis (p = 0.075). An association between p53 expression and high histological grade was observed (p = 0.039). TNBC patients with loss of BRCA1 expression had a tendency to have poorer overall survival (OS) than those positive for BRCA1 (p = 0.09). TNBC patients with positive p53 expression showed better OS than those with p53 negativity (p = 0.001). In terms of combined expression patterns, significantly poorer overall survival (OS) was observed for BRCA1-negative/p53-negative TNBCs and best OS for BRCA1-positive/p53-positive TNBCs (p = 0.005).Conclusions
Combined expression patterns of BRCA1 and p53 could serve as useful prognostic markers in TNBC.15.
Purpose
Choosing a surgical approach to treat adolescent idiopathic scoliosis (AIS) is still controversial. To compare the effectiveness and safety of combined anterior–posterior approach to posterior-only approach, we conducted a meta-analysis.Methods
We searched electronic database for relevant studies that compared anterior–posterior approach with posterior approach in AIS. Then data extraction and quality assessment were conducted. We used RevMan 5.1 for data analysis. A random effects model was used for heterogeneous data, while a fixed effect model was used for homogeneous data.Results
A total of ten non-randomized controlled studies involving 872 patients were included. There was no significant difference in Cobb angle (95 % CI ?0.33 to 4.91, P = 0.09) and percent-predicted FEV1 (95 % CI ?6.79 to 4.54, P = 0.70) between the two groups. In subgroup analysis, the kyphosis angle correction was significantly higher than posterior group in severe subgroup (95 % CI 0.72–6.50, P = 0.01), while no significant difference was found in no-restriction subgroup (95 % CI ?2.75 to 5.42, P = 0.52). Patients in posterior group obtained a better percent-predicted FVC than those in anterior–posterior group (95 % CI ?13.18 to ?4.74, P < 0.0001). Significant less complication rate (95 % CI 2.75–17.49, P < 0.0001), blood loss (95 % CI 363.28–658.91, P < 0.00001), operative time (95 % CI 2.65–3.45, P < 0.00001) and length of hospital stay (95 % CI 1.98–22.94, P = 0.02) were found in posterior group.Conclusions
Posterior-only approach can achieve similar coronal plane correction and percent-predicted FEV1 compared to combined anterior–posterior approach. The posterior approach even does better in sagittal correction in severe AIS patients. Significantly less complication rate, blood loss, operative time, length of hospital stay and better percent-predicted FVC are also achieved by posterior-only approach. Posterior-only approach seems to be effective and safe in treating AIS for experienced surgeons.16.

Purpose
Trauma patients with diabetes mellitus (DM) represent a unique population as the acute injury and the underlying disease may both cause hyperglycemia that leads to poor outcomes. We investigated how insulin-dependent DM (IDDM) and noninsulin-dependent DM (NIDDM) impact mortality after serious trauma without brain injury.Methods
The National Trauma Data Bank (NTDB) version 7.0 was queried for all patients with moderate to severe traumatic injury [injury severity score (ISS) >9]. Patients were excluded if missing data, age <10 years, severe brain injury [head abbreviated injury scale (AIS) >3], dead on arrival or any AIS = 6. Logistic regression modeled the association between DM and mortality as well as IDDM, NIDDM and mortality.Results
Overall 166,103 trauma patients without brain injury were analyzed. Mortality was 7.6 and 4.4 % in patients with and without DM, respectively (p < 0.01). Mortality was 9.9 % for patients with IDDM and 6.7 % for NIDDM (p < 0.01). The increased mortality associated with DM was only significantly higher for DM patients in their forties (5.6 vs. 3.3 %, p < 0.01). Regression analyses demonstrated that DM (AOR 1.14, p = 0.04) and IDDM (AOR 1.46, p < 0.01) were predictors of mortality compared to no DM, but NIDDM was not (AOR 1.02, p = 0.83).Conclusions
While DM was a predictor for higher mortality after serious trauma, this increase was only observed in IDDM and not NIDDM. Our findings suggest IDDM patients who present after serious trauma are unique and attention to their hyperglycemia and related insulin therapy may play a critical role in recovery.17.

Purpose
To identify risk factors that may lead to the development of dysphagia after combined anterior and posterior (360°) cervical fusion surgery.Methods
A single center, retrospective analysis of patients who had same-day, 360° fusion at Henry Ford Hospital between 2008 and 2012 was performed. Variables analyzed included demographics, medical co-morbidities, levels fused, and degree of dysphagia.Results
The overall dysphagia rate was 37.7 %. Patients with dysphagia had a longer mean length of stay (p < 0.001), longer mean operative time (p < 0.001), greater intraoperative blood loss (p = 0.002), and fusion above the fourth cervical vertebra, C4, (p = 0.007). There were no differences in the rates of dysphagia when comparing patients undergoing primary or revision surgery (p = 0.554).Conclusion
Prolonged surgery and fusion above C4 lead to higher rates of dysphagia after 360° fusions. Prior anterior cervical fusion does not increase the risk of dysphagia development.18.

Purpose
We estimated the annual changes in radiographic indices of the spine in cerebral palsy (CP) patients and analyzed the factors that influence its progression rate.Methods
We included CP patients who had undergone whole-spine radiography more than twice and were followed for at least 1 year. The scoliosis Cobb angle, coronal balance, apical vertebral translation, apical rotation, and pelvic obliquity were measured on anteroposterior (AP) radiographs; thoracic kyphosis and lumbar lordosis angles, and sagittal balance was measured on lateral radiographs; and migration percentage was measured on AP hip radiographs to determine hip instability. For each gross motor function classification system (GMFCS) level, the Cobb angles, apical vertebral translation, coronal and sagittal balance, and pelvic obliquity were adjusted by multiple factors with a linear mixed model.Results
A total of 184 patients (774 radiographs) were included in this study. There was no significant annual change in scoliosis Cobb, thoracic kyphosis, and lumbar lordosis angles in the GMFCS level I–II and III groups. In the GMFCS level IV–V group, there was an annual increase of 3.4° in the scoliosis Cobb angle (p = 0.020). The thoracic kyphosis angle increased by 2.2° (p = 0.018) annually in the GMFCS level IV–V group. Apical vertebral translation increased by 5.4 mm (p = 0.029) annually in the GMFCS level IV–V group. Progression of coronal and sagittal balance and pelvic obliquity with aging were not statistically significant. Sex, hip instability, hip surgery, and triradiate cartilage did not affect the progression of scoliosis and the balance of the spine and pelvis.Conclusions
The scoliosis Cobb angle, thoracic kyphosis angle, and apical vertebral translation in the GMFCS level IV–V CP patients progressed with age. These findings can predict radiographic progression of scoliosis in CP patients.19.

Background and objectives
Hepatic resection is established as the treatment for HCC. However, patients sometimes experience early recurrence of HCC (ER HCC) after curative resection.Methods
A retrospective analysis was conducted for 193 patients with single HCC who underwent curative liver resection in our medical center between April 2000 and March 2013. We divided the cohort into two groups; early recurrence group (ER G) which experienced recurrence within 6 months after resection, and non-early recurrence group (NER G). Risk factors for ER HCC were analyzed.Results
Thirty-nine out of 193 (20.2 %) patients had ER HCC. Univariate analysis showed Glasgow prognostic score (GPS, p = 0.036), neutrophil to lymphocyte ratio (NLR, p = 0.001), level of PIVKA-II (p = 0.0001), level of AFP (p = 0.0001), amounts of blood loss (p = 0.001), operating time (p = 0.002), tumor size (p = 0.0001), stage III and IV (p = 0.0001), and microvascular invasions (portal vein: p = 0.0001 and hepatic vein: p = 0.001) to be associated with ER HCC. By multivariate analysis, there were significant differences in high NLR (p = 0.029) and high AFP (p = 0.0001) in patients with ER HCC.Conclusions
Preoperative high AFP (more than 250 ng/ml) and high NLR (more than 1.829) were independent risk factors for ER HCC.20.
