Background context Only Level 3 evidence exists for the diagnosis and treatment of atlantooccipital dislocation (AOD) with few studies examining mortality, neurologic improvement, and patient-reported outcomes (PROs). Purpose First, the aim was to determine: the incidence of AOD, 90-day surgical morbidity and mortality after AOD, patient factors that may be associated with delayed or missed diagnosis, and factors that were associated with mortality and neurologic improvement after AOD. Secondly, the aim was to quantify the pain, disability, and quality of life experienced by patients surviving AOD. Study design/setting This was a retrospective cohort study. Patient sample A total of 5,337 consecutive spine computed tomography traumagrams from 1997 to 2012 were included. Outcome measures Mortality, neurologic improvement, complications, EuroQol five dimensions (EQ-5D), Neck Disability Index (NDI), Numeric Rating Scale (NRS)-neck, NRS-arm, and return-to-work were the outcome measures. Methods Patients were considered to have AOD if they met one of the following radiographic criteria: basion-dens interval greater than 10 mm; basion-axial interval: anterior displacement greater than 12 mm or posterior displacement greater than 4 mm between the basion and posterior C2 line; and condyle to C1 interval greater than 1.4 mm. Linear regression analysis was performed to identify factors associated with 90-day mortality, neurologic improvement, and missed diagnosis. Patient-reported outcomes were assessed via phone interview. Results Thirty-one patients met radiographic criteria for AOD; an incidence of 0.6% over 15 years. Twenty-one (68%) patients were treated with occipital cervical fusion. At 90 days postoperatively, there were no new neurologic deficits or reoperations. Eight (26%) patients died within 90 days. All patients who died had no documented AOD diagnosis and were not treated surgically. Missed AOD diagnosis was the strongest predictor of mortality. Younger age, lower Glasgow Coma Score, lower Injury Severity Score (ISS) score, and worse initial American Spinal Injury Association (ASIA) score were significantly associated with greater neurologic improvement. Higher ISS score and better ASIA score were significantly associated with missed AOD diagnosis. The average PROs metrics at time of telephone follow-up were as follows: EQ-5D=0.73±0.19, NDI=30.89±18.57, NRS-neck=2.33±2.21, NRS-arm=2.00±2.54. Of the patients with follow-up data, four were employed full-time, and five were receiving disability. Conclusions Our work suggests that failure to diagnose AOD is a powerful predictor of mortality. Higher ISS scores and better neurologic presentation were significantly associated with missed diagnosis. Craniocervical arthrodesis preserved neurologic function with low complication rate and unexpectedly high PROs and return-to-work. These results must be carefully interpreted because it is unclear whether missed AOD diagnosis accompanies another death-causing injury (eg, traumatic brain injury) or if failure to treat AOD contributes to mortality in a multifactorial manner.

Study design Mixed retrospective-prospective cohort study. Objective To characterize practice patterns for the use of Cell Saver at our institution, investigate its cost-effectiveness, and propose a new tool for patient selection. Summary of background data Blood loss is an exceedingly common complication of spine surgery, and Cell Saver intraoperative cell salvage has been used to decrease reliance on allogeneic blood transfusions for blood volume replacement. The cost-effectiveness of Cell Saver has not been established for lumbar spinal surgery, and no universal guidelines exist for clinicians to decide when to utilize this tool. Other authors have proposed cutoffs for anticipated blood loss volumes which indicate that Cell Saver should be used. Methods Five hundred and eight patients undergoing lumbar laminectomy in 3 or fewer levels were reviewed from our prospective spinal outcomes registry. Cost information for Cell Saver and allogeneic transfusions was collected from our institution's billing and collections department. Logistic regression was used to identify patient characteristics associated with use of Cell Saver. An incremental cost effectiveness ratio was calculated based on transfusion and cost data. A clinical prediction score was derived using logistic regression. Results Use of Cell Saver correlated with increased age, higher body mass index, diabetes, greater American Society of Anesthesiologists classification, and greater number of previous spine surgeries. Outcomes for patients who did and did not have Cell Saver set up intraoperatively were equivocal. Cell Saver was not cost effective based on current usage patterns, but may become cost effective if used for patients with high expected blood loss. A simple clinical prediction rule is proposed which may aid in selection of patients to have Cell Saver present intraoperatively. Conclusion Cell Saver is not a cost-effective intervention but may become cost effective if a threshold of expected intraoperative blood loss is used to select patients more judiciously. Level of evidence 3.

Hybrid Capture 2 (HC2) has been demonstrated to be a feasible screening method for cervical cancer. Based upon HC2 technology, careHPV is a simple, rapid, accurate, and inexpensive screening test for women in low-resource settings. This study aims to characterize both the careHPV test and HC2 test, and to compare careHPV results of specimens stored in careHPV test collection medium (TCM) to HC2 results from partner specimens stored in Qiagen specimen transport medium and TCM. The positive rates of high-risk HPV in careHPV, HC2, and HC2 (TCM) were 13.2% (108/818), 13.2% (108/818), and 13.6% (111/818), respectively. The agreement rates of pairwise tests were 95.8% (95% CI: 94.5-97.2%), 96.7% (95% CI: 95.5-97.9%), and 97.2% (95% CI: 96.1-98.3%), respectively. The Kappa values of the pairwise tests were 0.82 (95% CI: 0.76-0.88), 0.86 (95% CI: 0.81-0.91), and 0.88 (95% CI: 0.83-0.93), respectively. Based on these findings, although careHPV is demonstrated to be a viable alternative to the HC2 test, improvements on the careHPV test are still required prior to its implementation as a suitable screening method for women in low-resource settings. Further studies on the significance and applicability of the careHPV test must be performed.

OBJECTIVES To describe and investigate the injury pattern and outcomes of high-energy transsyndesmotic ankle fracture dislocations, or "Logsplitter" injuries, in which the talus is axially wedged into the tibiofibular joint. DESIGN Prospective Cohort Study. SETTING Level 1 trauma center. PATIENTS Prospective evaluation of 23 high-energy transsyndesmotic ankle fracture dislocations (OTA 44-B). INTERVENTION Operative fixation. MAIN OUTCOME MEASUREMENTS Radiographs, clinical examination, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale, Short Musculoskeletal Function Assessment. RESULTS Fracture characteristics included 52% open fractures (all medial) and syndesmotic widening of 30.7 ± 11.9 mm. The tibial plafond was involved in 11 (48%) of 23 injuries, with 5 (22%) Chaput, 5 (22%) posterior malleolar fragments, and 6 (26%) with articular impaction. A fibula fracture occurred in all but 1 patient, on average 64.2 ± 40.0 mm above the distal tip. All patients had fixation of their fibular and medial malleolar fractures, 21 of 23 patients had syndesmotic screws, and 8 of 23 had tibial plafond fixation. Anatomic alignment (within

Encounters with racist patients can be distressing, damage the physician-patient relationship, and threaten the collegial environment of the health care setting. Although policies guiding physician interactions may exist, providers may be uncomfortable and left vulnerable in racially charged interactions. When providers deal with racially intolerant patients, a courteous address of their inappropriate behavior is crucial, after which a dialogue should ensue to identify causes of potentially misplaced anger. Unsuccessful attempts at relationship salvage should be further guided by ethics teams, and in cases of a continued impasse, physicians should absolve themselves of medical duties provided that an appropriate alternative provider is available. Although racism in the health care setting can present a reasonable window to generate productive dialogue to improve race relations, a deeply entrenched and pervasive mindset can be difficult to reverse and should not impede the primary goal of providing timely patient care.

Background Liquid-state specimen carriers are inadequate for sample transportation in large-scale screening projects in low-resource settings, which necessitates the exploration of novel non-hazardous solid-state alternatives. Studies investigating the feasibility and accuracy of a solid-state human papillomavirus (HPV) sampling medium in combination with different down-stream HPV DNA assays for cervical cancer screening are needed. Methods We collected two cervical specimens from 396 women, aged 25–65 years, who were enrolled in a cervical cancer screening trial. One sample was stored using DCM preservative solution and the other was applied to a Whatman Indicating FTA Elute® card (FTA card). All specimens were processed using three HPV testing methods, including Hybrid capture 2 (HC2), careHPV™, and Cobas®4800 tests. All the women underwent a rigorous colposcopic evaluation that included using a microbiopsy protocol. Results Compared to the liquid-based carrier, the FTA card demonstrated comparable sensitivity for detecting high grade Cervical Intraepithelial Neoplasia (CIN) using HC2 (91.7 %), careHPV™ (83.3 %), and Cobas®4800 (91.7 %) tests. Moreover, the FTA card showed a higher specificity compared to a liquid-based carrier for HC2 (79.5 % vs. 71.6 %, P = 0.015), comparable specificity for careHPV™ (78.1 % vs. 73.0 %, P > 0.05), but lower specificity for the Cobas®4800 test (62.4 % vs. 69.9 %, P = 0.032). Generally, the FTA card-based sampling medium’s accuracy was comparable with that of liquid-based medium for the three HPV testing assays. Conclusions FTA cards are a promising sample carrier for cervical cancer screening. With further optimization, it can be utilized for HPV testing in areas of varying economic development.

Background. Incidence rates of breast cancer continue to rise in the People's Republic of China. The purpose of this study was to describe Chinese trends in radical surgical modalities and influential imaging and demographic factors for breast malignancies. Materials and Methods. This study was a hospital-based, multicenter, 10-year (1999–2008), retrospective study. Descriptive statistical tests were used to illustrate information regarding radical surgical trends for the treatment of breast malignancies. Chi-square tests were used to assess effect of demographic factors in addition to imaging and pathological data on the specific surgical method. Results. A total of 4,211 patients were enrolled in the survey. Among them, 3,335 patients with stage 0 to stage III disease undergoing mastectomy or breast-conserving surgery (BCS) were included in the final analysis. The rate of BCS increased from 1.53% in 1999 to 11.88% in 2008. The rate of mastectomy declined over this time period, from 98.47% in 1999 to 88.12% in 2008, with increasing use of diagnostic imaging methods and pathological biopsies. A significantly greater percentage of patients with office work, high education levels, unmarried status, younger age, and early pathological stages preferred BCS compared with mastectomy. Conclusion. Rates of mastectomy in China remain elevated due to diagnosis at higher stages; however, because of increased use of diagnostic imaging, improvement of biopsy methods, and patient education, rates of less invasive lumpectomy are increasing and rates of mastectomy have decreased in China. Implications for Practice: In this study, 4,211 cases were collected from 1999 to 2008 through a multicenter retrospective study of varying geographic and socioeconomic areas to illustrate trends of surgeries in the People's Republic of China. The correlations between demographic and tumor characteristics and among methods of surgical treatment were explored. This study shows that the rate of breast-conserving surgery (BCS) increased and the rate of mastectomy declined over this time period with increasing use of diagnostic imaging methods and pathological biopsies. Patients with office work, high education levels, unmarried status, younger age, and early pathological stages preferred BCS compared with mastectomy in China.

Objective: To describe characteristics and outcomes of Jordanian newborns admitted to a large governmental neonatal intensive care unit (NICU). Methods: Newborns born at the government hospital, Al Bashir, in Amman, Jordan were prospectively enrolled. The study focused on newborns admitted to the NICU and a retrospective chart review was performed. Abstraction included in-hospital mortality, antibiotic days, ventilation, oxygen use, and CRP levels. Rank sum and chi-squared tests were used to compare across outcomes. Logistic regression of hypothesized risk factors with death adjusted for gestational age. Results: Of the 5,466 neonates enrolled from 2/10-2/11, medical records were available for 321/378(84.9%) infants admitted to the NICU. The median gestational age was 36 weeks, median birth weight was 2.3 kg, and 28(8.7%) infants died. The two most common reasons for admission and mortality were respiratory distress syndrome and prematurity. Low Apgar scores and positive CRP were predictors of mortality. Risk factors associated with increased use of antibiotics, oxygen hood, and mechanical ventilation included lower gestational age and prematurity. Conclusion: Infants admitted to the Jordanian NICU have significantly higher median gestational age and birth weights than in developed countries and were associated with significant morbidity and mortality. Continuations of global efforts to prevent prematurity are needed.

Background and Objective. Incidence of and mortality rates for breast cancer continue to rise in the People's Republic of China. The purpose of this study was to analyze differences in characteristics of breast malignancies between China and the U.S. Methods. Data from 384,262 breast cancer patients registered in the U.S. Surveillance, Epidemiology, and End Results (SEER) program from 2000 to 2010 were compared with 4,211 Chinese breast cancer patients registered in a Chinese database from 1999 to 2008. Outcomes included age, race, histology, tumor and node staging, laterality, surgical treatment method, and reconstruction. The Pearson chi-square and Fisher's exact tests were used to compare rates. Results. Infiltrating ductal carcinoma was the most common type of malignancy in the U.S. and China. The mean number of positive lymph nodes was higher in China (2.59 vs. 1.31, p < .001). Stage at diagnosis was higher in China (stage IIA vs. I, p < .001). Mean size of tumor at diagnosis was higher in China (32.63 vs. 21.57 mm). Mean age at diagnosis was lower in China (48.28 vs. 61.29 years, p < .001). Moreover, 2.0% of U.S. women underwent radical mastectomy compared with 12.5% in China, and 0.02% in China underwent reconstructive surgery. Conclusion. Chinese women were diagnosed at younger ages with higher stage and larger tumors and underwent more aggressive surgical treatment. Prospective trials should be conducted to address screening, surgical, and tumor discrepancies between China and the U.S. Implications for Practice: Breast cancer patients in China are diagnosed at later stages than those in America, which might contribute to different clinical management and lower 5-year survival rate. This phenomenon suggests that an earlier detection and treatment program should be widely implemented in China. By comparing the characteristics of Chinese and Chinese-American patients, we found significant differences in tumor size, lymph nodes metastasis, and age at diagnosis. These consequences indicated that patients with similar genetic backgrounds may have different prognoses due to the influence of environment and social economic determinates.

BACKGROUND: College students are recommended as the target groups for catch-up human papillomavirus (HPV) vaccination. Systematical exploration of awareness acceptability and decision-making factors of HPV vaccination among Chinese college students has been limited. MATERIALS AND METHODS: A multi-center survey was conducted in mainland China between November 2011 and May 2012. College students aged 18-22 years were stratified by their grade gender and major for sampling. Socio-demographic and HPV-related information such as knowledge perceptions acceptability and attitudes were collected through a questionnaire. RESULTS: A total of 3497 undergraduates completed the questionnaire among which 1686 were males. The acceptability of the HPV vaccine was high (70.8%). Undergraduates from high-level universities at lower grade or with greater prior knowledge of HPV vaccines showed higher acceptability of HPV vaccination (ptrend
