Serum sex hormone-binding globulin levels are reduced and inversely associated with intrahepatic lipid content and saturated fatty acid fraction in adult patients with glycogen storage disease type 1a.

PURPOSE: De novo lipogenesis has been inversely associated with serum sex hormone-binding globulin (SHBG) levels. However, the directionality of this association has remained uncertain. We, therefore, studied individuals with glycogen storage disease type 1a (GSD1a), who are characterized by a genetic defect in glucose-6-phosphatase resulting in increased rates of de novo lipogenesis, to assess the downstream effect on serum SHBG levels. METHODS: A case-control study comparing serum SHBG levels in patients with GSD1a (n = 10) and controls matched for age, sex, and BMI (n = 10). Intrahepatic lipid content and saturated fatty acid fraction were quantified by proton magnetic resonance spectroscopy. RESULTS: Serum SHBG levels were statistically significantly lower in patients with GSD1a compared to the controls (p = 0.041), while intrahepatic lipid content and intrahepatic saturated fatty acid fraction-a marker of de novo lipogenesis-were significantly higher in patients with GSD1a (p = 0.001 and p = 0.019, respectively). In addition, there was a statistically significant, inverse association of intrahepatic lipid content and saturated fatty acid fraction with serum SHBG levels in patients and controls combined (ß: - 0.28, 95% CI: - 0.47;- 0.09 and ß: - 0.02, 95% CI: - 0.04;- 0.01, respectively). CONCLUSION: Patients with GSD1a, who are characterized by genetically determined higher rates of de novo lipogenesis, have lower serum SHBG levels than controls.

Preferences of people with Type 2 diabetes for diabetes care: a discrete choice experiment.

AIMS: Limited knowledge exists on the preferences of people with Type 2 diabetes towards diabetes care. Consequently, these care preferences cannot yet be considered in the development of tailored diabetes care approaches. Therefore, this study aimed to assess care preferences and their determinants in people with Type 2 diabetes. METHODS: A discrete choice experiment was conducted to elicit people's preferences. People with Type 2 diabetes, treated in 30 Dutch primary care practices, were asked to choose repeatedly between two hypothetical diabetes care packages, which differed in six attributes: role division in daily diabetes care planning, lifestyle education method, type of medication management support, consultation frequency, emotional support and time spend on self-management. A mixed-logit model was used to estimate the relative importance of the included attributes. Preference heterogeneity among people with different person- and disease-related characteristics was investigated. RESULTS: In total, 288 participants completed the experiment. They preferred to plan their daily diabetes care together with a healthcare provider, to receive individual lifestyle education, medication and emotional support from a healthcare provider, one consultation visit every 3 months and to spend less time on self-management. Participants did not prefer to receive emotional support from a psychologist. Heterogeneity in preferences could partly be explained by differences in sex, education level and glucose-lowering drug use. CONCLUSION: People with Type 2 diabetes show a preference for traditional care models. Emotional support was identified by participants as the most important attribute. It is therefore important to adequately guide them when changes in diabetes care organization are implemented.

Assessment of medical students' integrated clinical communication skills: development of a tailor-made assessment tool.

BACKGROUND: Since patient-centered communication is directly connected to clinical performance, it should be integrated with medical knowledge and clinical skills. Therefore, clinical communication skills should be trained and assessed as an integral part of the student's clinical performance. We were unable to identify a tool, which helps when assessing patient-centered communication skills as an integrated component of medical history taking ('the integrated medical interview'). Therefore, we decided to design a new tailor-made assessment tool, the BOCC (BeOordeling Communicatie en Consultvoering (Dutch), Assessment of Communication and Consultation (English) to help raters assess students' integrated clinical communication skills with the emphasis on patient-centred communication combined with the correct medical content. This is a first initiative to develop such a tool, and this paper describes the first steps in this process. METHODS: We investigated the tool in a group of third-year medical students (n = 672) interviewing simulated patients. Internal structure and internal consistency were assessed. Regression analysis was conducted to investigate the relationship between scores on the instrument and general grading. Applicability to another context was tested in a group of fourth-year medical students (n = 374). RESULTS: PCA showed five components (Communication skills, Problem clarification, Specific History, Problem influence and Integration Skills) with various Cronbach's alpha scores. The component Problem Clarification made the strongest unique contribution to the grade prediction. Applicability was good when investigated in another context. CONCLUSIONS: The BOCC is designed to help raters assess students' integrated communication skills. It was assessed on internal structure and internal consistency. This tool is the first step in the assessment of the integrated medical interview and a basis for further investigation to reform it into a true measurement instrument on clinical communication skills.

How do the characteristics of breast cancer diagnostic assessment programmes influence service delivery: A mixed methods study.

Diagnostic assessment programmes (DAPs) coordinate multidisciplinary teamwork (MDT), and improve wait times and patient satisfaction. No research has established optimal DAP design. This study explored how DAP characteristics influence service delivery. A mixed methods case study of four breast cancer DAPs was conducted including qualitative interviews with health-care providers and retrospective chart review. Data were integrated using multiple approaches. Twenty-three providers were interviewed; 411 medical records were reviewed. The number of visits and wait times from referral to diagnosis and consultation were lowest at a one-stop model. DAP characteristics (rural-remote region, human resources, referral volume, organisation of services, adherence to service delivery targets and one-stop model) may influence service delivery (number of visits, wait times). MDT, influenced by other DAP characteristics (co-location of staff, patient navigators, team functioning), may also influence service delivery. While the one-stop model may be ideal, all sites experienced similar and unique challenges. Further research is needed to understand how to optimise the organisation and delivery of DAP services. Measures reflecting individual, team and patient-reported outcomes should be used to assess the effectiveness and impact of DAPs in addition to more traditional measures such as wait times.

Challenges and insights in implementing coordinated care between oncology and primary care providers: a Canadian perspective.

We report here on the current state of cancer care coordination in Canada and discuss challenges and insights with respect to the implementation of collaborative models of care. We also make recommendations for future research. This work is based on the findings of the Canadian Team to Improve Community-Based Cancer Care Along the Continuum (canimpact) casebook project. The casebook project identified models of collaborative cancer care by systematically documenting and analyzing Canadian initiatives that aim to improve or enhance care coordination between primary care providers and oncology specialists. The casebook profiles 24 initiatives, most of which focus on breast or colorectal cancer and target survivorship or follow-up care. Current key challenges in cancer care coordination are associated with establishing program support, engaging primary care providers in the provision of care, clearly defining provider roles and responsibilities, and establishing effective project or program planning and evaluation. Researchers studying coordinated models of cancer care should focus on designing knowledge translation strategies with updated and refined governance and on establishing appropriate protocols for both implementation and evaluation.

The DULK (Dutch leakage) and modified DULK score compared: actively seek the leak.

AIM: A standardized postoperative score, the DULK (Dutch leakage) score, has been demonstrated to be a useful clinical tool in the diagnosis of anastomotic leakage. It is complicated, however, and a simplification (the modified DULK score) based on fewer parameters derived from multiple logistic regression analyses has been developed. These include clinical condition, abdominal pain not localized at the wound, C-reactive protein level and respiratory rate. The accuracy of each was compared. METHOD: Data of all patients from five Dutch centres operated on between 16 October 2007 and 1 November 2009 with an anastomosis in the colon or rectum were entered into a prospectively maintained database. RESULTS: In total, 782 patients were included of whom 81 (10.4%) had a clinically relevant anastomotic leakage. The DULK score gave an overall sensitivity of 97% for anastomotic leakage, overall specificity of 53%, a positive predictive value (PPV) of 16% and a negative predictive value (NPV) of 99%. The modified DULK score used clinical condition, abdominal pain not localized at the wound, C-reactive protein level and respiratory rate. With at least one parameter present, overall sensitivity was 97%, overall specificity 57%, PPV 17% and NPV 99.5%. With at least two points PPV was 41% and with three points 57%. CONCLUSION: Both the original and modified DULK scores are useful for the early diagnosis of clinically relevant anastomotic leakage. The modified DULK score offers the benefit of fewer parameters and so can easily be used in a clinical environment to estimate the likelihood of anastomotic leakage. However, the early diagnosis of anastomotic leakage remains difficult.

Plasma proprotein convertase subtilisin kexin type 9 levels are related to markers of cholesterol synthesis in familial combined hyperlipidemia.

BACKGROUND AND AIMS: Two recent independent studies showed that patients with familial combined hyperlipidemia (FCHL) have elevated plasma levels of proprotein convertase subtilisin kexin type 9 (PCSK9) and markers of cholesterol synthesis. Both PCSK9 expression and cholesterol synthesis are downstream effects of hepatic activation of sterol regulatory element binding protein 2 (SREBP2). The present study was conducted to study the relationship between plasma PCSK9 and markers of cholesterol synthesis in FCHL. METHODS AND RESULTS: Markers of cholesterol synthesis (squalene, desmosterol, lathosterol), cholesterol absorption (campesterol, sitosterol, cholestanol) and PCSK9 were measured in plasma of FCHL patients (n = 103) and their normolipidemic relatives (NLR; n = 240). Plasma PCSK9, lathosterol and desmosterol levels were higher in FCHL patients than their NLR (p < 0.001, age and sex adjusted). Heritability calculations demonstrated that 35% of the variance in PCSK9 levels could be explained by additive genetic effects (p < 0.001). Significant age- and sex-adjusted correlations were observed for the relationship between PCSK9 and lathosterol, both unadjusted and adjusted for cholesterol, in the overall FCHL population (both p < 0.001). Multivariate regression analyses, with PCSK9 as the dependent variable, showed that the regression coefficient for FCHL status decreased by 25% (from 0.8 to 0.6) when lathosterol was included. Nevertheless, FCHL status remained an independent contributor to plasma PCSK9 (p < 0.001). CONCLUSIONS: The present study confirms the previously reported high and heritable PCSK9 levels in FCHL patients. Furthermore, we now show that high PCSK9 levels are, in part, explained by plasma lathosterol, suggesting that SREBP2 activation partly accounts for elevated PCSK9 levels in FCHL.

Alignment of practice guidelines with targeted-therapy drug funding policies in Ontario.

BACKGROUND: We evaluated clinical practice guideline (cpg) recommendations from Cancer Care Ontario's Program in Evidence-Based Care (pebc) for molecularly targeted systemic treatments (tts) and subsequent funding decisions from the Ontario Ministry of Health and Long-Term Care. METHODS: We identified pebc cpgs on tt published before June 1, 2010, and extracted information regarding the key evidence cited in support of cpg recommendations and the effect size associated with each tt. Those variables were compared with mohltc funding decisions as of June 2011. RESULTS: From 23 guidelines related to 17 tts, we identified 43 recommendations, among which 38 (88%) endorsed tt use. Among all the recommendations, 38 (88%) were based on published key evidence, with 82% (31 of 38) being supported by meta-analyses or phase iii trials. For the 38 recommendations endorsing tts, funding was approved in 28 (74%; odds ratio related to cpg recommendation: 29.9; p = 0.003). We were unable to demonstrate that recommendations associated with statistically significant improvements in overall survival [os: 14 of 16 (88%) vs. 8 of 14 (57%); p = 0.10] or disease- (dfs) or progression-free survival [pfs: 16 of 21 (76%) vs. 3 of 5 (60%); p = 0.59] were more likely to be funded than those with no significant difference. Moreover, we did not observe significant associations between funding approvals and absolute improvements of 3 months or more in os [6 of 6 (100%) vs. 3 of 6 (50%), p = 0.18] or pfs [6 of 8 (75%) vs. 10 of 12 (83%), p = 1.00]. CONCLUSIONS: For use of tts, most recommendations in pebc cpgs are based on meta-analyses or phase iii data, and funding decisions were strongly associated with those recommendations. Our data suggest a trend toward increased rates of funding for therapies with statistically significant improvements in os.

Teaching and training in breaking bad news at the Dutch medical schools: a comparison.

BACKGROUND: Physicians consider breaking bad news (BBN) a difficult task, and training is therefore necessary. There is much variety in what schools consider to be best practice and best timing for such training. This article discusses BBN-programmes at the Dutch medical schools. We studied how students value their training and offer recommendations. METHODS: We developed two questionnaires to obtain programme information from course co-ordinators and student opinions about BBN-training. We compared student opinions right after BBN-training (T1) and towards the end of the medical curriculum (T2). RESULTS: BBN-programmes in Dutch medical schools vary in timing, models used and training methods. Overall, students are satisfied with the timing. They appreciate feedback by physicians and simulated patients most. At T2, some groups of students reported that BBN-training had given them slightly less guidance than was reported by T1-students at the same institution. DISCUSSION: T2-students perhaps realised they had not received the amount of support they needed and may have shifted from being unconsciously incompetent to being consciously incompetent. RECOMMENDATIONS: We recommend: (a) longitudinal programmes with experiential skills-training sessions and clinical practice, (b) to involve simulated patients, physicians and psychologists in training programmes as well as practising physicians who supervise students during clinical work and (c) to ensure ongoing support and feedback in the clinical phase.

High protein prescription in methylmalonic and propionic acidemia patients and its negative association with long-term outcome.

BACKGROUND AND OBJECTIVE: Methylmalonic acidemia (MMA) and propionic acidemia (PA) are inborn errors of metabolism. While survival of MMA and PA patients has improved in recent decades, long-term outcome is still unsatisfactory. A protein restricted diet is the mainstay for treatment. Additional amino acid mixtures (AAM) can be prescribed if natural protein is insufficient. It is unknown if dietary treatment can have an impact on outcome. DESIGN: We performed a nationwide retrospective cohort study and evaluated both longitudinal dietary treatment and clinical course of Dutch MMA and PA patients. Protein prescription was compared to the recommended daily allowances (RDA); the safe level of protein intake as provided by the World Health Organization. The association of longitudinal dietary treatment with long-term outcome was evaluated. RESULTS: The cohort included 76 patients with a median retrospective follow-up period of 15 years (min-max: 0-48 years) and a total of 1063 patient years on a protein restricted diet. Natural protein prescription exceeded the RDA in 37% (470/1287) of all prescriptions and due to AAM prescription, the total protein prescription exceeded RDA in 84% (1070/1277). Higher protein prescriptions were associated with adverse outcomes in severely affected patients. In PA early onset patients a higher natural protein prescription was associated with more frequent AMD. In MMA vitamin B12 unresponsive patients, both a higher total protein prescription and AAM protein prescription were associated with more mitochondrial complications. A higher AAM protein prescription was associated with an increased frequency of cognitive impairment in the entire. CONCLUSION: Protein intake in excess of recommendations is frequent and is associated with poor outcome.

Code status communication training in postgraduate oncology programs: a needs assessment.

Background: Discussions with patients with cancer about cardiopulmonary resuscitation directives (code status) are often led by residents. This study was carried out in Canada to identify current educational practices and gaps in training for this communication skill. Methods: Canadian medical and radiation oncology residents and program directors (pds) were surveyed about teaching practices, satisfaction with current education, and barriers to teaching code status discussion skills. Relative frequencies of categorical and ordinal responses were calculated. Results: Between November 2016 and February 2017, 95 (58.6%) of 162 residents and 17 (63%) of 27 pds completed surveys. Only 54.1% and 48.3% of medical and radiation oncology residents, respectively, had received any code status communication training before entering an oncology program. While 41% of residents expected to receive formal teaching on this topic during residency, 47.1% of pds endorsed inclusion of this topic in curricula. Only 20% of residents reported receiving formal evaluation of this skill while 41.2% of pds indicated that evaluations are provided. The importance of this communication skill in oncology was strongly supported. Among residents, 88% desired more training, and 82.3% of pds identified the need for new educational resources. Lack of time, resources, and evaluation tools were among the most commonly identified barriers to teaching. Conclusions: Oncology residency pds and trainees feel that code status communication is important, but teaching and evaluation of this skill are limited. Barriers to teaching and skill-building have been identified. Further work is underway to develop novel educational resources for code status communication training.

Organizational guidance for the care of patients with head-and-neck cancer in Ontario.

Background: At the request of the Head and Neck Cancers Advisory Committee of Ontario Health (Cancer Care Ontario), a working group and expert panel of clinicians with expertise in the management of head-and-neck cancer developed the present guideline. The purpose of the guideline is to provide advice about the organization and delivery of health care services for adult patients with head-and-neck cancer. Methods: This document updates the recommendations published in the Ontario Health (Cancer Care Ontario) 2009 organizational guideline The Management of Head and Neck Cancer in Ontario. The guideline development methods included an updated literature search, internal review by content and methodology experts, and external review by relevant health care providers and potential users. Results: To ensure that all patients have access to the highest standard of care available in Ontario, the guideline establishes the minimum requirements to maintain a head-and-neck disease site program. Recommendations are made about the membership of core and extended provider teams, minimum skill sets and experience of practitioners, cancer centre-specific and practitioner-specific volumes, multidisciplinary care requirements, and unique infrastructure demands. Conclusions: The recommendations contained in this document offer guidance for clinicians and institutions providing care for patients with head-and-neck cancer in Ontario, and for policymakers and other stakeholders involved in the delivery of health care services for head-and-neck cancer.

Occupational exposure to potential endocrine disruptors: further development of a job exposure matrix.

OBJECTIVES: The aim was to develop a new up-to-date and comprehensive job exposure matrix (JEM) for estimating exposure to potential endocrine disruptors in epidemiological research. METHODS: Chemicals with endocrine disrupting properties were identified from the literature and classified into 10 chemical groups: polycyclic aromatic hydrocarbons (PAHs), polychlorinated organic compounds, pesticides, phthalates, organic solvents, bisphenol A, alkylphenolic compounds, brominated flame retardants, metals and a miscellaneous group. Most chemical groups were divided into three to six subgroups. Focusing on the years 1996-2006, three experts scored the probability of exposure to each chemical group and subgroup for 353 job titles as "unlikely" (0), "possible" (1) or "probable" (2). Job titles with positive exposure probability scores were provided with exposure scenarios that described the reasoning behind the scores. RESULTS: Exposure to any chemical group was unlikely for 238 job titles (67%), whereas 102 (29%) job titles were classified as possibly (17%) or probably (12%) exposed to one or several endocrine disruptors. The remaining 13 job titles provided too little information to classify exposure. PAHs, pesticides, phthalates, organic solvents, alkylphenolic compounds and metals were often linked to a job title in the JEM. The remaining chemical groups were found to involve very few occupations. CONCLUSIONS: Despite some important limitations, this JEM could be a valuable tool for exposure assessment in studies on the health risks of endocrine disruptors, especially when task specific information is incorporated. The documented exposure scenarios are meant to facilitate further adjustments to the JEM to allow more widespread use.

Comparison of Frailty Scores in Newly Diagnosed Patients with Multiple Myeloma: A Review.

Multiple myeloma is a malignant plasma cell disease, which typically affects older patients, with a median age at diagnosis of 70 years. The challenge in treating older patients is to accurately identify 'fit' patients that can tolerate more intensive treatment to maximize disease control, while simultaneously identifying vulnerable or 'frail' patients who may develop toxicity with significant morbidity and mortality, requiring different treatment options or dose modification. Multiple frailty scores have been devised for multiple myeloma over the years in newly-diagnosed patients. This paper gives an overview of the three common frailty measurements: the International Myeloma Working Group Frailty Score, Mayo Clinic Frailty Score and the Revised Myeloma Co-Morbidity Index. We will summarize the derivation, validation, usability and applicability of these scores in different clinical settings, emphasizing the main strengths and limitations for each index score. We will also highlight future directions in the operationalization of frailty in multiple myeloma.

Lessons learned from a cancer knowledge translation grants program: results of an evaluation.

Background: A novel way to build capacity in knowledge translation (kt) is through kt-focused grant competitions. Since 2009, the Knowledge Translation Research Network (KT-Net) has had a cancer-related kt grants program. We undertook an evaluation of the program to determine if KT-Net was achieving its aims of building capacity in cancer kt, advancing the science of kt, building partnerships, and leveraging funding. Methods: An adapted framework guided the evaluation. Nine funded studies from 4 competitions were included. Semi-structured telephone interviews were held with researchers, stakeholders (including knowledge users), members of grant review panels, and experts in kt. Interview transcripts were audio-recorded, transcribed, and analyzed thematically. A review of proposal and report documents was also conducted. Results: Funded researchers indicated that the grant competition was an essential funding program for cancer kt research. Competitions were perceived to build capacity in cancer kt among early-career researchers and to encourage innovative cancer kt research for which alternative funding sources are limited. The grants program resulted in incremental gains in advancing the science of kt. Suggestions to improve the program included stronger partnerships between the funder and the provincial cancer-system organization to optimize the application of research that is relevant to the organization's strategic objectives. Conclusions: The grants program met many of its aims by providing cancer researchers with an opportunity to gain capacity in cancer kt and by making incremental advances in kt science. Suggestions to improve the program included closer partnerships between the funder and the cancer-system organization.

Plasma triglycerides and LDL cholesterol are related in a parabolic fashion in the general population and patients with Type 2 diabetes mellitus: long-term follow-up results from the Hoorn study.

AIMS: Low-density lipoprotein cholesterol (LDL-C) levels are often fairly normal in Type 2 diabetes mellitus (DM). We anticipated that a parabolic relation between plasma triglycerides and LDL-C, as previously demonstrated in familial combined hyperlipidaemia (FCHL), might account for this phenomenon. METHODS: Our hypothesis was tested in 1343 subjects derived from the general population who were studied on two occasions 6 years apart (the Hoorn study). Three groups were constructed depending on plasma triglycerides: group A (individuals with both measurements below 1.5 mmol/l), group B (one measurement below and one above 1.5 mmol/l) and group C (both measurements above 1.5 mmol/l). Diabetes status was ascertained by an oral glucose tolerance test. RESULTS: In a mixed linear model, a significant, positive relation between triglycerides and LDL-C was observed for males in group A (beta(a) = 0.5, P < 0.001) and group B (beta(b) = 0.2, P < 0.001), whereas a significant negative relation was found for males in group C (beta(c) = -0.2, P = 0.003). The regression slopes did not differ between diabetic and non-diabetic subjects. Similar results were obtained for women, with the exception that the relation was not significantly negative in group C (beta(c) = -0.1, P = 0.4). CONCLUSION: Plasma triglycerides and LDL-C are related in a parabolic fashion, not only in FCHL, but also in the general population and Type 2 DM. These findings aid our interpretation of typical dyslipidaemia and the effects of treatment that are frequently observed in hypertriglyceridaemic states.

Engaging cancer patients in clinical practice guideline development: a pilot study.

Background: Patient engagement is a key quality component of cancer guideline development; however, the optimal strategy for engaging patients in guideline development remains unclear. The feasibility and efficacy of two patient engagement models was tested by Cancer Care Ontario's cancer guideline development program, the Program in Evidence-Based Care (pebc). Methods: In model 1, patients participated in the guideline development process as active members of a working group. In model 2, patients formed a separate consultation group to review project plans and recommendations generated by multiple working groups. Training included online resources (model 1) and an in-person orientation (model 2). The pebc's standard patient engagement process acted as a control. The study was conducted for 1 year. Surveys measured the satisfaction of patients and members of the guideline working groups with the process and the outcome of each model. Results: Three guideline projects used model 1 to engage patients, six projects used model 2 to receive feedback, and one project was used as a control group (14 patients total). Most participants, whatever the model, reported satisfaction with their experience. Key challenges to implementation included patient recruitment and long wait times between meetings (model 1), and difficulty focusing on the discussion topic and poor meeting attendance on the part of patients (model 2). Conclusions: The pilot study demonstrated that, although both models are feasible and effective for the engagement of patients in cancer guideline development, modifications are required to optimize their continued interest. The pebc will use the study results to inform the implementation of a patient engagement strategy for its program.

Students' experiences with a longitudinal skills training program on breaking bad news: A follow-up study.

OBJECTIVE: Breaking bad news (BBN) should be trained, preferably early and following a helical model with multiple sessions over time, including feedback on performance. It's unclear how medical students evaluate such an approach. METHODS: We gathered student opinions regarding a helical BBN training programme, the feedback and emotional support they received, and the applicability of the skills training immediately after BBN skills training (Q1) and after finishing their clinical clerkships (Q2). RESULTS: Students find a helical curriculum useful, but this declines on follow-up. At Q2 students report less satisfaction with the amount of feedback and emotional support they received and report that the skills training was less applicable in clinical practice compared to what they reported at Q1. CONCLUSION: A helical BBN training programme with early exposure seems to lead to a shift from students being unconsciously incompetent to consciously incompetent. Students would have appreciated more emotional support and feedback. PRACTICE IMPLICATIONS: We recommend more feedback and emotional support after BBN during clerkships. The gap between classroom and practice can be diminished by emphasizing real life role play and clinical role models should demonstrate continuity and agreement between the skills that are taught and those that are used in clinical practice.

[Diversity of complaints in manifesting carcinoma of the gallbladder]. / Diversiteit in klachten bij manifestatie van het galblaascarcinoom.

A man of 47 years with hypercholesterolaemia had no complaints but the family doctor suspected cholecystolithiasis because of abnormal results of the haematological study. Ultrasonography of the abdomen revealed a polyp in the gallbladder. The patient underwent laparoscopic cholecystectomy. Pathological examination revealed that the polyp was a carcinoma. No evidence for a recurrence was found during a return visit after 2 years. A woman of 74 years was admitted to the hospital due to persistent rectal bleeding. She had fever, loss of appetite, nausea and weight loss. A bleeding duodenal ulcer was identified during gastroduodenoscopy. Laparotomy was performed due to haemodynamic instability. During the operation an abnormal gallbladder was found with infiltration in and perforation of the duodenum. The gallbladder was resected and the perforation of the duodenum was sutured. Pathological examination revealed carcinoma of the gallbladder. A palliative policy was adhered to; the patient died 1 month later. Carcinoma ofthe gallbladder is an uncommon but highly fatal malignancy. Several risk factors have been identified and treatment is primarily surgical.

Promoting best gynecologic oncology practice: a role for the Society of Gynecologic Oncologists of Canada.

During March 30-April 1, 2005, the Society of Gynecologic Oncologists of Canada (GOC) and the Canadian Strategy for Cancer Control (CSCC) Clinical Practice Guidelines Action Group (CPG-AG) met to determine how GOC would like to influence practice in the care of women with gynecologic cancer.explore a collaborative model for developing and implementing evidence-based practice guidelines.investigate the utility of the cpg evaluation and adaptation cycle as a tool for selecting, adapting, and adopting guidelines.At the workshop meeting, 21 members of the GOC and the cpg-ag heard presentations from various Canadian guideline initiatives. As an example of adaptation and adoption processes, the AGREE (Appraisal of Guidelines for Research and Evaluation) tool was applied to guidelines in recurrent ovarian cancer, and the group explored their opportunity to use knowledge translation to influence the care of women with gynecologic cancer.The themes influencing practice are consistent with GOC's mandate. The future is expected to involve partnering with other groups to maximize scarce resources. Resources should be directed to facilitating implementation of existing guidelines rather than to developing new documents. The full spectrum of cancer care includes prevention, screening, diagnosis, primary treatment, follow-up, treatment of recurrent disease, and palliation. High-quality evidence is available in some areas, but gaps exist where guideline panels could provide guidance. Development of a pan-Canadian gynecologic oncology process could provide an opportunity to influence access to care at the political and policy levels.The GOC will develop linkages such that the toolbox available through CSCC-CPG-AG can be incorporated into future collaboration.
