Canadian Cardiovascular Society/Canadian Anesthesiologists' Society/Canadian Heart Rhythm Society joint position statement on the perioperative management of patients with implanted pacemakers, defibrillators, and neurostimulating devices

There are more than 200,000 Canadians living with permanent pacemakers or implantable defibrillators, many of whom will require surgery or invasive procedures each year. They face potential hazards when undergoing surgery; however, with appropriate planning and education of operating room personnel, adverse device-related outcomes should be rare. This joint position statement from the Canadian Cardiovascular Society (CCS) and the Canadian Anesthesiologists' Society (CAS) has been developed as an accessible reference for physicians and surgeons, providing an overview of the key issues for the preoperative, intraoperative, and postoperative care of these patients. The document summarizes the limited published literature in this field, but for most issues, relies heavily on the experience of the cardiologists and anesthesiologists who contributed to this work. This position statement outlines how to obtain information about an individual's type of pacemaker or implantable defibrillator and its programming. It also stresses the importance of determining if a patient is highly pacemaker-dependent and proposes a simple approach for nonelective evaluation of dependency. Although the document provides a comprehensive list of the intraoperative issues facing these patients, there is a focus on electromagnetic interference resulting from electrocautery and practical guidance is given regarding the characteristics of surgery, electrocautery, pacemakers, and defibrillators which are most likely to lead to interference. The document stresses the importance of preoperative consultation and planning to minimize complications. It reviews the relative merits of intraoperative magnet use vs reprogramming of devices and gives examples of situations where one or the other approach is preferable.     

The development and validation of the hypertension evaluation of lifestyle and management knowledge scale

Hypertension knowledge is an integral component of the chronic care model. A valid scale to assess hypertension knowledge and self-management skills is needed. The hypertension evaluation of lifestyle and management (HELM) scale was developed as part of a community-based study designed to improve self-management of hypertension. Participants included 404 veterans with hypertension. Literature review and an expert panel were used to identify required skills. Items were generated and pilot tested in the target population. Validity was assessed through comparisons of performance with education, health numeracy, print numeracy, patient activation and self-efficacy, and hypertension control. The HELM knowledge scale had 14 items across 3 domains: general hypertension knowledge, lifestyle and medication management, and measurement and treatment goals. Scores were positively associated with education (0.28, P<.0001), print health literacy (0.21, P<.001), health numeracy (0.17, P<.001), and patient activation (0.12, P=.015) but no association was found with diastolic or systolic blood pressure. The HELM knowledge scores increased following the educational intervention from baseline (mean, 8.7; standard deviation, 2.2) to 12-month follow-up (mean, 9.2, standard deviation, 2.2; P<.001). We conclude that the HELM provides a valid measure of the knowledge required for patients to take an active role in the chronic disease management of hypertension.     

Impact of trainee involvement with robotic-assisted radical prostatectomy

Robotic-assisted surgery has been rapidly adopted within urology practice. As a result, academic centers are challenged with the burden of how to effectively train residents and fellows to perform robotic-assisted surgery without compromising outcomes. We evaluated the perioperative outcomes of trainee involvement with robotic-assisted radical prostatectomy (RARP) within our healthcare organization. We retrospectively reviewed RARP cases performed at our institution between September 2008 and December 2010 using a single da Vinci robotic platform. Trainees consisted of urology residents and fellows who operated with staff surgeons on select operating days, whereas two staff surgeon teams performed RARP on alternate days. We compared clinicopathologic variables including operating time, estimated blood loss, surgical margin rates, and complication rates between the trainee and staff-only surgeon groups. Overall, 1,019 RARP surgeries were performed within the study period and trainees participated in 162 cases (16 %). Clinical characteristics were similar between men undergoing surgery with a trainee and those without. Positive surgical margin rates were lower for patients with pT2 disease for cases with trainee involvement (11 vs. 19 %, p = 0.02), although overall margin rates and margin rates for patients with pT3 disease were similar between the groups (p = 0.34). Surgical cases involving trainees were longer (241 vs. 200 min, p < 0.001) and resulted in higher estimated blood loss (190 vs. 120 mL, p < 0.001) than the two staff surgeon cases. However, transfusion rates as well as intraoperative and postoperative complication rates did not differ significantly between groups. In conclusion, surgical margin rates were lower in teaching cases for patients with pT2 disease. Importantly, trainee involvement in RARP is safe, with similar perioperative outcomes to staff-only surgical cases. This information may be useful for training and surgical planning.     

A randomized study of open-flap surgery of 32 intrabony defects with and without adjunct bovine bone mineral treatment

Background: Bovine bone mineral (BBM) is extensively used as a filler material in periodontal reconstructive surgery of intrabony defects. Data are mostly available on the combined use of BBM with other biomaterials. The aim of this study is to evaluate healing after open‐flap debridement (OF) of intrabony periodontal defects alone or with adjunct treatment with BBM. Methods: After initial treatment, 32 patients with 32 intrabony periodontal defects participated in the study. Full‐thickness flaps were raised and root surfaces and defects were debrided. Patients were then randomly assigned to treatment groups, either OF alone or combined with defect fill with BBM, and followed in a strict postoperative maintenance care program for 12 months. Results: At 12 months, a mean ± SE gingival recession of 1.1 ± 0.3 mm in OF and 0.9 ± 0.4 mm in BBM occurred. Probing depth reduction was 4.0 ± 0.5 mm in OF and 3.2 ± 0.7 mm in BBM. Gain in clinical attachment level was 2.8 ± 0.6 mm in OF and 2.3 ± 0.8 mm in BBM. Probing bone level was reduced by 2.7 ± 0.7 mm in OF and 1.8 ± 1.1 mm in BBM. None of the above parameters showed significant intergroup differences. In contrast, radiographic defect depth change was significantly greater in BBM (3.4 ± 2.3 mm) than in OF (1.9 ± 1.7 mm). Conclusions: Both treatments resulted in improved periodontal conditions. The adjunctive use of BBM in this study did not enhance the clinical result compared to OF alone.     

Solution-Focused Brief Therapy for the Treatment of Sexual Disorders

The purpose of this article is to describe the use of solution-focused brief therapy (SFBT) as an approach to sex therapy. SFBT has been used to treat most clinical problems and populations, but until now has not been offered as an approach to sexual problems. This article describes SFBT and discusses its applications to sex therapy. A case example is included.
