Abstract
The ESA-JAXA BepiColombo mission to Mercury will provide simultaneous measurements from two spacecraft, offering an unprecedented opportunity to investigate magnetospheric and exospheric particle dynamics at Mercury as well as their interactions with solar wind, solar radiation, and interplanetary dust. The particle instrument suite SERENA (Search for Exospheric Refilling and Emitted Natural Abundances) is flying in space on-board the BepiColombo Mercury Planetary Orbiter (MPO) and is the only instrument for ion and neutral particle detection aboard the MPO. It comprises four independent sensors: ELENA for neutral particle flow detection, Strofio for neutral gas detection, PICAM for planetary ions observations, and MIPA, mostly for solar wind ion measurements. SERENA is managed by a System Control Unit located inside the ELENA box. In the present paper the scientific goals of this suite are described, and then the four units are detailed, as well as their major features and calibration results. Finally, the SERENA operational activities are shown during the orbital path around Mercury, with also some reference to the activities planned during the long cruise phase.

Abstract
Background A positive circumferential resection margin (CRM) has been associated with higher rates of locoregional recurrence and worse survival in oesophageal cancer. The aim of this study was to establish if clinicopathological and radiological variables might predict CRM positivity in patients who received neoadjuvant chemotherapy before surgery for oesophageal adenocarcinoma. Methods Multivariable analysis of clinicopathological and CT imaging characteristics considered potentially predictive of CRM was performed at initial staging and following neoadjuvant chemotherapy. Prediction models were constructed. The area under the curve (AUC) with 95% confidence intervals (c.i.) from 1000 bootstrapping was assessed. Results A total of 223 patients were included in the study. Poor differentiation (odds ratio (OR) 2·84, 95 per cent c.i. 1·39 to 6·01) and advanced clinical tumour status (T3-4) (OR 2·93, 1·03 to 9·48) were independently associated with an increased CRM risk at diagnosis. CT-assessed lack of response (stable or progressive disease) following chemotherapy independently corresponded with an increased risk of CRM positivity (OR 3·38, 1·43 to 8·50). Additional CT evidence of local invasion and higher CT tumour volume (14 cm3) improved the performance of a prediction model, including all the above parameters, with an AUC (c-index) of 0·76 (0·67 to 0·83). Variables associated with significantly higher rates of locoregional recurrence were pN status (P = 0·020), lymphovascular invasion (P = 0·007) and poor response to chemotherapy (Mandard score 4-5) (P = 0·006). CRM positivity was associated with a higher locoregional recurrence rate, but this was not statistically significant (P = 0·092). Conclusion The presence of advanced cT status, poor tumour differentiation, and CT-assessed lack of response to chemotherapy, higher tumour volume and local invasion can be used to identify patients at risk of a positive CRM following neoadjuvant chemotherapy.

Abstract
Vitis vinifera is affected by many diseases every year, depending on causal agents, susceptibility of cultivars, and climate region. Some are caused by a single agent, such as gray mold caused by Botrytis cinerea or powdery mildew caused by Erysiphe necator. Others result from the actions of a complex of pathogens such as grapevine trunk diseases (GTDs). GTDs are presently among the most devastating diseases in viticulture worldwide because both the economic losses and the long-term sustainability of vineyards are strongly affected. The complexity of GTDs results from the diversity of associated fungi, the undetermined period of latency within the vine (asymptomatic status), the erratic foliar symptom expression from one year to the next, and, probably correlated with all of these points, the lack of efficient strategies to control them. Distinct methods can be beneficial to improve our knowledge of GTDs. In vitro bioassays with cell suspensions, calli, foliar discs, full leaves, or plantlets, and in vivo natural bioassays with cuttings, grafted plants in the greenhouse, or artificially infected ones in the vineyard, can be applied by using progressive integrative levels of in vitro and in vivo, depending on the information searched. In this review, the methods available to understand GTDs are described in terms of experimental procedures, main obtained results, and deliverable prospects. The advantages and disadvantages of each model are also discussed.

Abstract
Debilitating and persistent fear memories can rapidly form in humans following exposure to traumatic events. Fear memories can also be generated and studied in animals via Pavlovian fear conditioning. The current study was designed to evaluate basolateral amygdala complex (BLC) involvement following the formation of different fear memories (two contextual fear memories and one adjusted auditory fear memory). Fear memories were created in the same context with five 1.0 mA (0.50 s) foot-shocks and, where necessary, five auditory tones (5 kHz, 75 dB, 20 s). The adjusted auditory fear conditioning protocol was employed to remove background contextual fear and produce isolated auditory fear memories. Immunofluorescent labeling was utilized to identify neurons expressing immediate early genes (IEGs). We found the two contextual fear conditioning (CFC) procedures to produce similar levels of fear-related freezing to context. Contextual fear memories produced increases in BLC IEG expression with distinct and separate patterns of expression. These data suggest contextual fear memories created in slightly altered contexts, can produce unique patterns of amygdala activation. The adjusted auditory fear conditioning procedure produced memories to a tone, but not to a context. This group, where no contextual fear was present, had a significant reduction in BLC IEG expression. These data suggest background contextual fear memories, created in standard auditory fear conditioning protocols, contribute significantly to increases in amygdala activation.

Abstract
OBJECTIVES To examine the relationship between early life episodes of otitis media and later behavioural development with adjustment for confounders. DESIGN Longitudinal cohort study. SETTING The Western Australian Pregnancy Cohort (Raine) Study recruited 2900 pregnant women from King Edward Memorial Hospital (KEMH) in Perth, Western Australia, between 1989 and 1991. PARTICIPANTS Data from the children born were collected at both the Year 3 and Year 5 follow-up. At Year 3, n = 611 were diagnosed with recurrent otitis media through parent-report and clinical examination. At Year 5, n = 299 were considered exposed to otitis media based upon tympanometry results. MAIN OUTCOME MEASURES Performance in the Child Behaviour Checklist (CBCL), a questionnaire completed by the primary caregiver at Year 10. RESULTS Significant associations were found between recurrent otitis media at Year 3 and internalising behaviours (P = .011), and the somatic (P = .011), withdrawn (P = .014), attention (P = .003) and thought problems domains (P = .021), and the total CBCL score (P = .010). A significant association was also found between exposure to otitis media at Year 5 and externalising behaviours (P = .026). CONCLUSIONS A modest association was seen between recurrent otitis media at Year 3 and exposure to otitis media at Year 5 and a number of behaviour domains at Year 10.

Abstract
OBJECTIVES To examine the long-term effects of predominant breastfeeding on incidence of otitis media. DESIGN Prospective birth cohort study. SETTING The West Australian Pregnancy Cohort (Raine) Study recruited 2900 mothers through antenatal clinics at the major tertiary obstetric hospital in Perth, Western Australia, between 1989 and 1992. PARTICIPANTS In total, 2237 children participated in a 6-year cohort follow-up, and a subset of 1344 were given ear and hearing assessments. MAIN OUTCOME MEASURES OM diagnosis at 6 years of age (diagnosed by low-compliance tympanograms, 0-0.1 mmho). This was compared to OM diagnosed at the 3-year cohort follow-up using parent-report measures. Main exposure measures were duration of predominant breastfeeding (defined as the age other milk was introduced) and duration of partial (any) breastfeeding (defined as the age breastfeeding was stopped). RESULTS There was a significant, independent association between predominant breastfeeding (OR = 1.33 [1.04, 1.69]; P = 0.02) and OM, and breastfeeding duration (OR = 1.35 [1.08, 1.68]; P = 0.01) with OM at 3 years of age. However, at 6 years of age, this relationship was no longer statistically significant (predominant breastfeeding OR = 0.78 [0.48, 1.06]; P = 0.09; duration of breastfeeding, OR = 1.34 [0.81, 2.23]; P = 0.25). CONCLUSIONS Our findings are in line with a number of epidemiological studies which show a positive association between breastfeeding and OM in early childhood. However, the long-term follow-up of these children revealed that by 6 years of age, there was no significant influence of breastfeeding on presence of OM. These results suggest that the protective effect of predominant breastfeeding for at least 6 months does not extend to school-age children, where other social and environmental factors may be stronger predictors of OM.

Abstract
In the mid-1980s, the licensing authorities in Quebec, Ontario and Manitoba have introduced programs to conduct in-depth assessments of the clinical skills and abilities of physicians with suspected deficiencies. These assessments are intended to supplement the provincial licensing authorities' existing peer review or patient-complaint mechanisms by confirming the physicians' overall level of competence and identifying specific clinical strengths and weaknesses. An "educational prescription", based on the results of the assessment, focuses on aspects of clinical practice in which the physicians need or wish to enhance their skills. In some situations, licensure decisions are based on the assessment information. This article describes the programs in Quebec, Ontario and Manitoba. Each program comprises a different process of personal assessment and individualized continuing medical education to help physicians improve their clinical competence, and each is built on sound principles of clinical competence assessment and educational planning.

Abstract
69 Background: We hypothesized that CRM size affect survival and local recurrence for OC and GOJ cancer. We also assessed the utility of CT in predicting margin status. Methods: A retrospective analysis of a prospective database was carried out on all patients who had esophagectomy between January 2000 and July 2008. Patients diagnosed with OC and GOJ tumors on final pathologic examination were included. Distance from the CRM was assessed by a specialist upper GI pathologist. Two radiologists, blinded to postoperative margin status, reviewed preoperative CT scans using 16 separate parameters, comparing them to measured CRM status. Results: 419 patients were assessed. 223 pts had OC or GOJ type 1 tumors, average age 62 years (range 36–80), mean follow-up 5.8 years (2-9.5). There were 125 deaths and median overall survival (OS) 3.33 years (95% CI 2.76-6.24). 76 patients had recurrence at a median of 1.3 years (0.1-4.7). For 144 patients had OC or GOJ type 1 T3 tumors. Selected results are presented in the Table. There was no CRM size above which there was no further reduction in recurrence. Postoperative chemoradiation did not improve OS (p=0.79) or recurrence (p=0.96) in patients with CRM of 0-1 mm. In 50 patients the CT parameters significantly correlated with margin status were largest axial diameter (p=0.003) and contact with adjacent structures (p=0.005). A complete statistical review with multivariate and subgroup analyses will be presented. Conclusions: CRM size is strongly correlated with survival and recurrence in OC and type 1 GOJ tumors. Prediction of a close CRM could be used to select for more intensive therapy prior to undergoing radical surgery, such as chemoradiation. Preoperative CT can help in this prediction.

Abstract
During acute viral hepatitis, the intrahepatic tolerance sustained by immunosuppressive cytokines such as interleukin (IL)-4, IL-10, transforming growth factor (TGF)-beta and prostaglandin E2 (PGE2), produced by Kupffer cells (KC), liver sinusoidal endothelial cells (LSEC), natural killer (NK) T cells and natural regulatory T cells may be disturbed. NK cells are recruited normally in the liver and produce interferon (IFN)-gamma to control viral replication. The use of mouse hepatitis virus type 3 (MHV3) attenuated variants showing selected tropisms for KC or LSEC have allowed determining their roles in the disturbances of immune tolerance during viral hepatitis. Groups of C57BL/6 mice were infected with the pathogenic L2-MHV3 (KC+, LSEC+), low attenuated 51.6-MHV3 (KC+, LSEC-) or high attenuated CL12-MHV3 (KC-, LSEC-) variants for the first 3 days. Results showed that IL-10, TGF-beta and PGE2 production in the liver decreased in L2-MHV3-infected mice and increased in 51.6-MHV3- and CL12-MHV3-infected mice. The ratio of IFN-gamma/IL-4 in liver decreased in L2-MHV3-infected mice, while it was not (or low) altered in mice infected with the attenuated MHV3 variant mice. Phenotypic analysis of intrahepatic mononuclear cells revealed that apoptotic NK and NK T cells increased in mice infected with the L2-MHV3, but were minor in 51.6-MHV3- and CL12-MHV3-infected mice. The numbers of CD4+ forkhead box P3+ cells increased in the livers from low pathogenic CL12-MHV3 and YAC-MHV3-infected mice. These results indicate that viral permissivity of KC and LSEC is involved in the decrease of IL-10 and PGE2, while KC may play an additional role in the apoptosis of NK and NK T cells during acute viral hepatitis.

Abstract
Different functions have been attributed to natural regulatory CD4+CD25+FOXP+ (Treg) cells during malaria infection. Herein, we assessed the role for Treg cells during infections with lethal (DS) and non-lethal (DK) Plasmodium chabaudi adami parasites, comparing the levels of parasitemia, inflammation and anaemia. Independent of parasite virulence, the population of splenic Treg cells expanded during infection, and the absolute numbers of activated CD69+ Treg cells were higher in DS-infected mice. In vivo depletion of CD25+ T cells, which eliminated 80% of CD4+FOXP3+CD25+ T cells and 60-70% of CD4+FOXP3+ T cells, significantly decreased the number of CD69+ Treg cells in mice with lethal malaria. As a result, higher parasite burden and morbidity were measured in the latter, whereas the kinetics of infection with non-lethal parasites remained unaffected. In the absence of Treg cells, parasite-specific IFN-gamma responses by CD4+ T cells increased significantly, both in mice with lethal and non-lethal infections, whereas IL-2 production was only stimulated in mice with non-lethal malaria. Following the depletion of CD25+ T cells, the production of IL-10 by CD90(-) cells was also enhanced in infected mice. Interestingly, a potent induction of TNF-alpha and IFN-gamma production by CD4+ and CD90(-) lymphocytes was measured in DS-infected mice, which also suffered severe anaemia earlier than non-depleted infected controls. Taken together, our data suggest that the expansion and activation of natural Treg cells represent a counter-regulatory response to the overwhelming inflammation associated with lethal P.c. adami. This response to infection involves TH1 lymphocytes as well as cells from the innate immune system.

Abstract
BACKGROUND This study, sponsored and conducted by Le Collège des Médecins du Québec, audited the management of acute appendicitis in the Province of Québec (Population 7.6 million), Canada, over a period of 1 year (April 2002-March 2003). METHODS A questionnaire was sent to the Health Records Department of all hospitals surgically treating appendicitis in the province. Data from 85 (100%) hospitals were received and reviewed. RESULTS During the study period, 7,599 appendectomies were performed, and 5,707 (75%) were selected for study (55% men). The rate of normal and perforated appendix was 5.4% and 15.9% respectively. Median hospital stay for simple and perforated appendicitis was 2.6 and 5.8 days, respectively. At least one imaging procedure was done in 86% of cases (23% computed tomography [CT], 55% ultrasound). Antibiotics were not given in 7% of cases and in 8% of patients with a perforation. Seventeen percent of patients did not receive preoperative or intraoperative doses, and postoperatively, 69% of patients received unnecessary doses. Laparoscopy was used in 35% of cases and was associated with a reduction in postoperative stay for simple (2.6 versus 2.9 days, p < 0.001) and perforated appendicitis (4.6 versus 5.9 days, p = 0.004). A low rate of laparoscopy (<25%) was found in 53% of teaching (University and Affiliated) and 45% of nonteaching institutions. Conversion to open surgery was necessary in 9.7% of simple appendicitis and 29.3% of perforated ones (p < 0.001). CONCLUSIONS Although results of this survey are comparable to those of similar published series, a few concerns emerge. Many have to do with patient noncompliance with recommended antibiotic usage for acute appendicitis. Further, although laparoscopy seems to be slowly making its way into the surgical armamentarium, the low rate of laparoscopic appendectomies in teaching hospitals raises the issue of appropriate resident training.

Abstract
BACKGROUND Little is known about how physicians' knowledge of and attitudes to practice guidelines for stable angina may influence their implementation. AIM To explore the association between physicians' demographics, their knowledge, and opinions about stable angina and their self-reported adherence to guideline recommendations. DESIGN Questionnaire-based survey. METHODS We surveyed 1228 Quebec physicians using a questionnaire based on the 'awareness-to-adherence' conceptual framework to measure their adherence with recommendations for the pharmacological treatment of stable angina. Independent predictors of adherence with the targeted recommendations were determined by stepwise linear regression analysis. RESULTS We received 877 (71.4%) responses from the 1228 eligible physicians. More than 90% of respondents were aware of and agreed with the targeted recommendations. However, the adoption rate varied, even among physicians who generally agreed with the guidelines. Factor analysis indicated that most physicians agreed with recommendations concerning ASA. More negative attitudes were expressed toward beta-blockers and hypolipaemic drugs. Respondents trusted the recommendations of a variety of scientific and professional organizations. Awareness, agreement, and adoption were the strongest predictors of adherence for the three recommendations. Physician demographics and practice characteristics did not predict adherence. DISCUSSION Physicians were aware of and agreed with the recommendations, so additional large-scale dissemination of the guidelines would be unlikely to improve prescription patterns. However, negative attitudes about beta-blockers and hypolipaemic therapy affected adherence to recommendations for these drugs. Continuing medical education interventions involving local opinion leaders might address some of the obstacles identified.

Abstract
Mouse hepatitis virus type 3 (MHV3), a coronavirus, is an excellent animal model for the study of immunological disorders related to acute and chronic hepatitis. In this study, we have verified if the fulminant hepatitis induced by MHV3 could be related to an impairment of innate immunity. Groups of three C57BL/6 mice were infected with the pathogenic L2-MHV3 or attenuated YAC-MHV3 viruses, and the natural killer (NK) cell populations from liver, spleen and bone marrow were analysed. The percentage of intrahepatic NK1.1(+)T cell receptor (TCR)- cells did not increase while NK1.1(+)TCR(inter) cells decreased in both L2-MHV3- and YAC-MHV3-infected mice. Concurrently, splenic and myeloid NK1.1+ cells decreased in L2-MHV3-infected mice. However, the cytotoxic activity of NK cells increased in liver and decreased in bone marrow from pathogenic L2-MHV3-infected mice while no modification was detected in YAC-MHV3-infected mice. Flow cytometric analysis revealed that both normal and larger splenic or myeloid NK cells decreased more in pathogenic L2-MHV3-infected mice than in attenuated YAC-MHV3-infected mice. In vitro viral infections of interleukin (IL)-15-stimulated lymphoid cells from liver and bone marrow revealed that L2-MHV3 induced higher decreases in cell viability of NK1.1+ cells than the YAC-MHV3 variant. The NK cell decreases were due to the viral permissivity leading to cytopathic effects characterized by cell rounding, syncytia formation and apoptosis. Larger NK+ syncytia were observed in L2-MHV3-infected cells than in YAC-MHV3-infected cells. These results suggest that NK cell production is impaired by viral infection favouring fulminant hepatitis.

Abstract
BACKGROUND Public agencies responsible for implementing health care policies often adapt and disseminate clinical practice guidelines, but the effectiveness of mass dissemination of guidelines is unknown. AIM To study the effects of guideline dissemination on physicians' prescribing practices for the treatment of stable angina pectoris. DESIGN Randomized controlled trial. METHODS A sample of 3293 Quebec physicians were randomly assigned to receive a one-page summary of clinical practice guidelines on the treatment of stable angina (in February 1999), to receive the summary and a reminder (in February and March 1999, respectively), or to receive no intervention (controls). The prescribing profiles of participants, as well as sociodemographic characteristics of the physicians and their patients, were examined for June-December 1999. RESULTS The intervention had no effect on prescription rates of beta-blockers, antiplatelet agents, or hypolipaemic drugs. Compared to 1997 data for the same physicians, there was an overall 10% increase in appropriate prescription rates, irrespective of the intervention. DISCUSSION In-house production and dissemination of clinical practice guidelines may not improve physicians' practice patterns if there is pre-existing substantial scientific consensus on the issue.

Abstract
There is good evidence for the use of antiplatelet, beta-blocker and lipid-lowering drugs in the treatment of ischaemic heart disease, but few data on how these medications are used in treating stable angina pectoris. We examined prescription profiles for a sample of patients aged > or =65 years with stable angina, to compare the profiles to local guidelines and to explore the determinants of these profiles, in a cross-sectional study. We identified 11 141 individuals from the Quebec provincial out-patient pharmaceutical database for the period 1 June 1996 to 31 May 1997, and examined the percentage of these patients with and without associated co-morbidities receiving antiplatelet, beta-blocker and lipid-lowering medications. We used hierarchical modelling to examine the role of patient and physician characteristics in explaining the variation in the use of these medications. Calcium-channel blockers were the class of anti-ischaemic drugs most prescribed (63%). Beta-blockers were prescribed in 52.1% of patients. Antiplatelet and lipid-lowering drugs were prescribed to 56.8% and 32.6%, respectively. Increasing age and female gender made patients less likely to be prescribed these treatments. General practitioners were less likely than cardiologists to prescribe beta-blockers and lipid-lowering drugs (OR 0.79, CI 95% 0.68-0.91 and OR 0.77, CI 95% 0.66-0.91, respectively). There is a general under-use of antiplatelet, beta-blocker and lipid-lowering medications in the treatment of stable angina pectoris patients, possibly leading to adverse patient outcomes.

Abstract
Scottish mental health legislation permits 'guardianship' for certain mentally impaired individuals, which imposes a requirement on place of residence, access and attendance at specified services for treatment and rehabilitation. The use of guardianship for alcohol-related brain damage increased steeply in the years 1993-1998. Possible explanations include: (1) increased prevalence or diagnosis of these conditions; (2) reduction of hospital beds; (3) a trend towards diminishing family and social support; (4) increased social work involvement in caring for such individuals; (5) increased consideration of the use of guardianship; (6) new private residential services; (7) lack of interest in the condition by existing services. There have been legal and clinical concerns about such individuals under guardianship relating to quality of ongoing clinical assessment, need for specific treatment and for the management of associated psychiatric illness, issues over control of drinking and control of personal finances, uncertainty over the use of restraint, and need for programmes helping the individual's progress towards independent living.

Abstract
We studied the acute effects of apneas and hypopneas on blood pressure in a nonclinic population of middle-aged adults. Arterial pressure was measured noninvasively (photoelectric plethysmography) during an overnight, in-laboratory polysomnographic study in 72 men and 23 women enrolled in the Wisconsin Sleep Cohort Study, a population-based study of sleep-disordered breathing. Sleep-disordered breathing events (272 apneas and 1469 hypopneas) were observed in 92% of subjects. The across-subject mean decreases in arterial O2 saturation were 9+/-8% (SD) for apneas (17+/-8 seconds duration) and 4+/-3% for hypopneas (21+/-6 seconds duration; 41+/-17% of baseline ventilation). In both apneas and hypopneas, even those with only 1% to 3% O2 desaturations, blood pressure decreased during the event, followed by an abrupt increase in the postevent recovery period. Mean values for peak changes in blood pressure (difference between the maximum during the recovery period and the minimum during the event) were 23+/-10 mm Hg for systolic and 13+/-6 mm Hg for diastolic pressure. The strongest predictors of the pressor responses to apneas and hypopneas were (in order of importance): magnitude of the ventilatory overshoot, length of the event, magnitude of changes in heart rate and arterial O2 saturation, and presence or absence of electroencephalographic arousal. We speculate that these fluctuations may play a role in the pathogenesis of hypertension in individuals with subclinical sleep-disordered breathing.

Abstract
OBJECTIVE To compare the continuing medical education (CME) activities of family physicians in the province of Quebec with more than 25 years in practice with those with less than 25 years in practice. DESIGN Mailed questionnaire survey. SETTING Family practices in the province of Quebec. PARTICIPANTS All physicians (n = 722) with more than 25 years in practice (expressed as older) and a matched sample of 721 physicians with less than 25 years in practice (expressed as younger). MAIN OUTCOME MEASURES Types of CME activities and time spent on them, participant characteristics. RESULTS Older physicians spent more time in individual CME activities than younger ones (21 hours vs 18 hours monthly). Younger physicians, however, spent more time in group CME activities than older ones did (100 hours vs 80 hours yearly). Excluding physicians who devoted no time to CME activities, only two activities differentiated between the two groups: older physicians spent more time than their younger colleagues reading and listening to audiocassettes. CONCLUSIONS Older physicians maintained their clinical competence by participating in different CME activities from younger physicians. They participated in as many CME activities as their younger colleagues.

Abstract
When should remedial continuing medical education (CME) be compulsory for family physicians? When should it be optional? Should it be structured or not? In 1993-1994, the authors addressed this need for criteria by conducting a study that used reports on 14 physicians who had undergone a structured oral interview (SOI) at the College of Physicians of Quebec. (The SOI is a day-long encounter during which two specially trained physician-interviewers present a physician with standardized clinical cases that focus on ten specific aspects of a family physician's competence.) The 14 SOI reports were reviewed by 12 external physician-judges in an attempt to see how consistently they could link the ten aspects of competence, as shown in the reports, to five particular types of recommended remedial CME programs (the strictest being "compulsory program with suspended license" and the most lenient being "simple suggestions for improvement"). There was substantial agreement among the judges when choosing between compulsory and optional programs (kappa = 0.63, p < .05). The main criteria used when recommending an optional program were overall strengths and the quality of clinical reasoning. The same two criteria were also used for recommending a compulsory program, but the judges also considered three additional factors: the physician's ability to recognize his or her limits and how he or she handled referrals and prescribed medications. Many of the criteria used by the judges were based on unique information that came out of observations and interactions during the SOIs, such as quality of argumentation, sustaining a train of thought, sense for the case as a whole, or awareness of one's limits. Finally, the external judges corroborated the decisions previously made by the College of Physicians of Quebec concerning the appropriate CME programs for the 14 physicians.

Abstract
Effective management of drug therapy in the elderly is a challenge for primary-care physicians. There are 20,400 drugs approved for marketing in Canada. Most elderly patients will fill 33 prescriptions per year and take 5 different medications. To be a safe prescriber in the 1990s, physicians need to be aware that 33,000 drug interactions, 6,500 drug-disease contraindications, and 3,500 drug-allergy contraindications have been documented. Inappropriate prescribing is a problem in the elderly. At least one inappropriate prescription is given to 12% to 46% of seniors, and 25% of drug-related hospital admissions are due to prescribing errors. Half of all physicians will write at least one inappropriate prescription for an elderly patient each year, and one quarter of inappropriate prescriptions will be created by the presence of multiple prescribing physicians. Academic detailing is the most effective approach to improve physician prescribing. However, it is an expensive intervention that must be limited to a small number of drugs and conditions, and it must be continued to retain its effectiveness. Furthermore, it fails to address the problems created by multiple prescribers. In this project, we developed a prototype of the future office practice. Physicians are equipped with personal computers and expert prescribing-system software. This electronic academic detailer reviews all current medications for a patient, identifies therapeutic duplications, generates alerts for 50 prescribing problems that have been identified as clinically relevant by a Canadian expert panel, suggests suitable alternatives, and reviews all new prescriptions for potential problems. Information on all prescriptions received by the physicians' elderly patients is downloaded weekly from the provincial prescription claims database, so that the primary physician is able to coordinate and manage all drugs prescribed to their patients by all physicians. The effectiveness of this intervention is being evaluated in a randomized controlled trial of 110 physicians and approximately 16,000 elderly patients in Montreal. We will test whether the intervention reduces the rate of inappropriate prescribing, as well as the rate of drug-related injuries and hospitalizations among patients treated by physicians in the experimental group.
