Single-Stage Posterior Approach for the En Bloc Resection and Spinal Reconstruction of T4 Pancoast Tumors Invading the Spine.

STUDY DESIGN: Retrospective cohort study. PURPOSE: This study aimed to evaluate the outcomes of patients who had T4 Pancoast tumors invading the spine and underwent en bloc resection and spinal stabilization through a single-stage posterior approach. OVERVIEW OF LITERATURE: Surgical resection for Pancoast tumors affecting the spine has been successfully performed in two stages involving spinal reconstruction and tumor resection. However, reports have rarely presented the results of en bloc resection combined with spinal stabilization for T4 Pancoast tumors invading the spine through a single-stage posterior approach. METHODS: Patients who had T4N0M0 Pancoast tumors invading the spine and underwent a single-stage posterior approach were retrospectively recruited. The following data were obtained and examined: demographics, tumor histology, preoperative and postoperative therapy, complications, spinal reconstruction technique, tumor resection extent, survival time, and disease recurrence. RESULTS: Eighteen patients were included. The mean population age was 61±17 years, and the most common pathological type was adenocarcinoma (61.1%). Complete resection (R0) was obtained in 15 patients (83.3%), positive surgical margins (R1) were found in three patients (16.7%), and the 90-day mortality rate was 0%. Postoperative major complications were detected in 12 patients (66.7%), who required reoperation. The mean survival time was 67±24 months, but the median survival time was not reached. Among the patients, 10 (55.6%) are still alive at the end of the study. The 2- and 5-year actual survival rates were 59% (95% confidence interval [CI], 35.7%-82.3%) and 52.5% (95% CI, 28.4%-76.6%), respectively. CONCLUSIONS: En bloc resection and spinal stabilization through a single-stage posterior approach might be effective for T4 Pancoast tumors invading the spine.

Cervical Spine Reconstruction with Chest Tube Technique After Metastasis Resection: A Single-Center Experience.

BACKGROUND: The silastic tube technique, in which a chest tube is placed into the vertebral body defect and impregnated with polymethyl methacrylate, showed good results in patients with lumbar and thoracic neoplastic diseases. There has been only 1 study about the effectiveness and safety of this technique in patients with cervical metastases. We aimed to report our experience in using this technique to reconstruct the spine after corpectomy for cervical metastasis. METHODS: All patients with cervical spinal metastasis who underwent surgical treatment using a chest tube impregnated with polymethyl methacrylate in conjunction with anterior cervical plate stabilization were retrospectively recruited. Demographics, tumor histology, revised Tokuhashi score, preoperative and postoperative American Spinal Injury Association score, preoperative and postoperative ambulatory status, perioperative complications, and survival time were collected. RESULTS: This study included 16 patients. The most common primary tumor site was the lung (6 patients; 37.5%). The mean (SD) survival time was 408 (795) days (range, 1-2797 days), and the median survival time was 72 days (95% confidence interval 28-116 days). Four patients (25%) died within 30 postoperative days. There was no surgical site infection or instrument failure after the surgery. Five patients (31.2%) lived >180 days, and 3 patients (18.8%) lived >360 days. One patient (6.2%) was still alive at the end of the study. CONCLUSIONS: The silastic tube technique in conjunction with anterior cervical plate stabilization might be safe, effective, and cost-effective for patients with cervical spine metastasis.

Measuring and Predicting Service Providers' Use of an Evidence-Based Parenting Program.

This study addressed the predictors of service providers' use of a multi-level evidence-based program (EBP). Of the 92 trained providers participating in the study, 67 (72.8%) used the EBP at least once. A multidimensional index of the amount of usage (MUI) was created using three indicators. Providers' self-efficacy and the amount of training they had received predicted their amount of usage. The community to which the providers belonged was also associated with their amount of usage. The findings underline the importance of studying many indicators of usage in implementation research and considering both provider-level and broader contextual variables as determinants of the use of EBPs.

Development and pretest of key visual imagery in a campaign for the prevention of child maltreatment.

INTRODUCTION: This article discusses the development and pretesting of key visual imagery in a promotional campaign developed in Quebec, Canada. This campaign is the media-based component of a broader prevention strategy involving the use of the Triple P program (Sanders, 1999). OBJECTIVES: The purpose was to pretest with parents the preliminary version of a poster that uses the campaign's key visual imagery prior to final production. METHOD: In total, 26 parents from the regions of Quebec City and Montreal participated in four focus groups. RESULTS: Two general themes emerged from the focus groups: (i) emotions and reactions arising from the key visual imagery; and (ii) comprehension of the message being conveyed. CONCLUSION: Based on this information, recommendations were made to the marketing agency, which then modified the campaign's key visual imagery and proposed a final layout.

Emotional and Sexual Correlates of Child Sexual Abuse as a Function of Self-Definition Status.

Among individuals defined as having been sexually abused based on legal criteria, some will self-report having been abused and some will not. Yet, the empirical correlates of self-definition status are not well studied. Different definitions of abuse may lead to varying prevalence rates and contradictory findings regarding psychological outcomes. The present study examined whether, among legally defined sexual abuse survivors, identifying oneself as having experienced childhood sexual abuse (CSA) was associated with more severe abuse, negative emotional reactions toward the abuse, and current sexual reactions. A convenience sample of 1,021 French-speaking Canadians completed self-report questionnaires online. The prevalence of legally defined CSA was 21.3% in women and 19.6% in men, as compared to 7.1% in women and 3.8% in men for self-defined CSA. Among legally defined sexual abuse survivors, those who identified themselves as CSA survivors had been abused more frequently, were more likely to report a male aggressor, and more often described abuse by a parental figure than those who did not self-identify as abused. Further, self-defined CSA was associated with more negative postabuse reactions and sexual avoidance, whereas those not identifying as sexually abused were more likely to report sexual compulsion.
