Training needs in adolescent medicine of practising doctors: a Swiss national survey of six disciplines.

OBJECTIVE: To assess and compare the training needs in adolescent medicine of doctors within 6 specialties as a basis for the development of pre/postgraduate and continuing medical education (CME) training curricula. DESIGN: Cross-sectional postal survey. SETTING: Switzerland. PARTICIPANTS: National, representative, random sample of 1857 practising doctors in 6 disciplines (general practitioners, paediatricians, gynaecologists, internists, psychiatrists, child psychiatrists) registered with the Swiss Medical Association. MAIN OUTCOME MEASURES: Perceived importance of and training interest in 35 topics related to adolescent medicine listed in a self-administered, anonymous questionnaire. RESULTS: A total of 1367 questionnaires were returned, representing a response rate of 73.9%. Clear interest in adolescent medicine was reported by 62.1% of respondents. Topics perceived to be the most important in everyday practice were functional symptoms (71.4%), acne (67.1%), obesity (64.6%), depression-anxiety (68.1%) and communication with adolescents (61.7%). Differences between disciplines were especially marked for gynaecologists, who expressed interest almost exclusively in medical topics specific to their field. In contrast, other disciplines commonly reported a keen interest in psychosocial problems. Accordingly, interest in further training was expressed mostly for functional symptoms (62.4%), eating disorders (56.3%), depression-anxiety (53.7%) and obesity (52.6%). Issues related to injury prevention, chronic disease and confidentiality were rated as low priorities. CONCLUSIONS: Regardless of discipline, Swiss primary care doctors expressed a strong interest in adolescent medicine. Continuing medical education courses should include both interdisciplinary courses and discipline-specific sessions. Further training should address epidemiological and legal/ethical issues (e.g. injury prevention, confidentiality, impact of chronic conditions).

Trials using a crossover design and ambulatory blood pressure recordings to determine the efficacy of antihypertensive agents in individual patients.

The antihypertensive effects of the beta-blocking agent betaxolol and the calcium entry blocker verapamil were compared in a crossover single-blind trial. Seventeen patients with uncomplicated essential hypertension took either betaxolol or a slow-release formulation of verapamil for two consecutive 6-week periods. The sequence of treatment phases was randomly allocated and a 2-week washout period preceded each treatment. The antihypertensive effect of the test drugs was assessed both at the physician's office and during everyday activities using a portable blood pressure recorder. The crossover design of the trial made it possible to evaluate the antihypertensive efficacy of betaxolol and verapamil both in the group as a whole and in the individual patient. The individual patient response to one of these agents was not a reliable indicator of the same patient's response to the alternative agent. Betaxolol brought both office and ambulatory recorded blood pressures under control in a larger fraction of patients than verapamil, although the magnitude of the blood pressure fall in the responders was equal for each drug. These observations stress the need for an individualized approach to the evaluation of antihypertensive therapy. The present results also demonstrate that optimal antihypertensive therapy is still a matter of trial and error. The precise methodology that ought to characterize crossover trials may make it possible to improve the therapeutic approach to hypertensive patients.

Sudden cardiac death in forensic medicine - Swiss recommendations for a multidisciplinary approach.

Sudden cardiac death (SCD) is by definition unexpected and cardiac in nature. The investigation is almost invariably performed by a forensic pathologist. Under these circumstances the role of the forensic pathologist is twofold: (1.) to determine rapidly and efficiently the cause and manner of death and (2.) to initiate a multidisciplinary process in order to prevent further deaths in existing family members. If the death is determined to be due to "natural" causes the district attorney in charge often refuses further examinations. However, additional examinations, i.e. extensive histopathological investigations and/or molecular genetic analyses, are necessary in many cases to clarify the cause of death. The Swiss Society of Legal Medicine created a multidisciplinary working group together with clinical and molecular geneticists and cardiologists in the hope of harmonising the approach to investigate SCD. The aim of this paper is to close the gap between the Swiss recommendations for routine forensic post-mortem cardiac examination and clinical recommendations for genetic testing of inherited cardiac diseases; this is in order to optimise the diagnostic procedures and preventive measures for living family members. The key points of the recommendations are (1.) the forensic autopsy procedure for all SCD victims under 40 years of age, (2.) the collection and storage of adequate samples for genetic testing, (3.) communication with the families, and (4.) a multidisciplinary approach including cardiogenetic counselling.

Gériatrie [Review in geriatric medicine 2014].

Several studies contributed to improving the diagnostic and prognostic assessment of delirium in hospitalized older patients. Direct patient education proved efficient in benzodiazepines withdrawal. A position statement of the American Geriatrics Society does not recommend tube feeding when eating difficulties arise in older persons suffering from advanced dementia. Several studies emphasized once again the potential importance of preventative interventions (in particular physical activity) to prevent or delay dementia occurrence. Two randomized controlled trials of monoclonal antibodies that bind amyloid did not show benefit in patients with mild-to-moderate Alzheimer's dementia (AD). In contrast, vitamin E reduced functional decline in these patients, and citalopram reduced agitation among AD patients as well as their caregiver's stress.

Communication du risque en médecine des voyages [Risk communication in travel medicine].

Les recommandations en termes de prévention contre la malaria pour les pays à risques modéré à faible diffèrent entre les pays, malgré le fait que les personnes soient exposées à un risque identique dans les pays qu'ils visitent. Pour inclure les voyageurs dans la réflexion, des outils de partage de la décision ont été développés et testés dans cette population. Leur utilisation a montré que la majorité des personnes choisissent de ne pas prendre de chimioprophylaxie en avançant des raisons valides. Le développement d'aides décisionnelles répondant à des critères reconnus est prévu et permettra d'améliorer la pertinence des recommandations. Les aides décisionnelles permettront aussi aux voyageurs de faire un choix de prévention avec les soignants au plus près de leurs valeurs et préférences, tout en respectant les règles de l'éthique médicale. Recommendations for malaria prevention for travelers planning a trip in medium to low risk countries differ between countries, despite the fact that people are exposed to the same risk in the travelled country. Decision aids have been developed and tested in a population of travelers planning a trip in such countries n order to present travelers the various prevention options and involve them in the decision. The use of the decision aid showed that he majority of people choose not to take chemoprophylaxis and that they could motivate their choice with valid reasons. The development of decision aids based on recognized quality criteria is foreseen; these will allow to improving the relevance of the recommendations and enable travelers to choose a prevention option that will be the closest to their values and preferences while following to the principles of medical ethics.

Mouthrinses: a comparative microbiological study

This study was performed in order to evaluate the efficacy of different mouthrinses whose use is extended in Spain. Six different antiseptic mouthrinses were studied by means of determination of Minimal Inhibitory Concentration (MIC) values against Klebsiella pneumoniae, Serratia marcescens, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhimurium, Bacillus subtilis, Streptococcus mutans, Prevotella intermedia, Porphyromonas gingivalis and Actinobacillus actinomycetemcomitans. Also in vivo experiments were carried out in volunteers by the use of mouthrinses and evaluation of bacterial populations before and after the treatment. Finally, the kinetics of bacterial death was determined. Results suggested that the determination of MIC values is not a reliable method to evaluate the antibacterial effect of such products. On the other hand those rinsing solutions based on the effect of oxygen, such as those containing carbamide peroxide have a greater efficacy against anaerobic bacteria compared with rinses whose active molecule is a disinfectant. Finally, the kinetics of bacterial death demonstrates that the essential oil rinse kills bacteria much faster. All tested mouthrinses were active as antibacterial although those based on oxygen production or essential oils were more active than solutions based on chlorhexidine and Triclosan

Diagnostic microbiologique de la pneumonie [Microbiological diagnosis of pneumonia].

Les pneumonies causent une mortalité et une morbidité significatives. De manière simplifiée, deux types de pneumonie sont décrits : la pneumonie communautaire et la pneumonie nosocomiale avec le pneumocoque et l'Haemophilus influenzae comme causes principales pour la première, le Pseudomonas et diverses entérobactéries pour la deuxième. La réalité est cependant plus complexe puisque l'on distingue aussi la pneumonie d'aspiration par exemple. La culture est très importante dans le cas des pneumonies nosocomiales car elle permet de déterminer la sensibilité aux antibiotiques de l'agent infectieux et d'adapter le traitement. Pour les patients immunosupprimés, le diagnostic différentiel est plus large et la recherche par tests moléculaires de certains virus, de champignons filamenteux et du Pneumocystis peut se révéler informative. Pneumonia is an importance cause of mortality and morbidity in adults. Two types of pneumonia are defined: community-acquired and nosocomial pneumonia with their corresponding etiology such as pneumococci or Haemophilus influenzae and Pseudomonas or enterobacteriaceae, respectively. However, the reality is more complex with aspiration pneumonia, pneumonia in immunocompromised patient, and pneumonia in ventilated patients. Culture in the case of nosocomial pneumonia is especially important to obtain the antibiotic susceptibility of the infectious agent and to adjust therapy. Moreover for immunocompromised patients, the differential diagnosis is much wider looking for viruses, filamentous fungi and Pneumocystis can be very informative, using new molecular assays.

2015 Update on Acute Adverse Reactions to Gadolinium based Contrast Agents in Cardiovascular MR. Large Multi-National and Multi-Ethnical Population Experience With 37788 Patients From the EuroCMR Registry.

OBJECTIVES: Specifically we aim to demonstrate that the results of our earlier safety data hold true in this much larger multi-national and multi-ethnical population. BACKGROUND: We sought to re-evaluate the frequency, manifestations, and severity of acute adverse reactions associated with administration of several gadolinium- based contrast agents during routine CMR on a European level. METHODS: Multi-centre, multi-national, and multi-ethnical registry with consecutive enrolment of patients in 57 European centres. RESULTS: During the current observation 37,788 doses of Gadolinium based contrast agent were administered to 37,788 patients. The mean dose was 24.7 ml (range 5-80 ml), which is equivalent to 0.123 mmol/kg (range 0.01 - 0.3 mmol/kg). Forty-five acute adverse reactions due to contrast administration occurred (0.12%). Most reactions were classified as mild (43 of 45) according to the American College of Radiology definition. The most frequent complaints following contrast administration were rashes and hives (15 of 45), followed by nausea (10 of 45) and flushes (10 of 45). The event rate ranged from 0.05% (linear non-ionic agent gadodiamide) to 0.42% (linear ionic agent gadobenate dimeglumine). Interestingly, we also found different event rates between the three main indications for CMR ranging from 0.05% (risk stratification in suspected CAD) to 0.22% (viability in known CAD). CONCLUSIONS: The current data indicate that the results of the earlier safety data hold true in this much larger multi-national and multi-ethnical population. Thus, the "off-label" use of Gadolinium based contrast in cardiovascular MR should be regarded as safe concerning the frequency, manifestation and severity of acute events.

Epidemiology and injury patterns of patients consulting following assault by nightclub security agents in a university hospital emergency service and an associated specialised forensic consultation

Introduction: The Violence Medical Unit (VMU), a specialised forensic medical consultation, was created at the Lausanne university Hospital in 2006. All patients consulting at the ED for interpersonal violencerelated injury are referred to the VMU, which provides forensic documentation of the injury and referral to the relevant community based victim-support organisations within 48 hours of the ED visit. This frees the ED medical staff from forensic injury documentation and legal/social referral, tasks for which they lack both time and training. Among community violence, assaults by nightclub security agents against patrons have increased from 6% to 10% between 2007 and 2009. We set out to characterise the demographics, assault mechanisms, subsequent injuries, prior alcohol intake and ED & VMU costs incurred by this group of patients. Methods: We retrospectively included all patients consulting at the VMU due to assault by nightclub security agents from January 2007 to December 2009. Data was obtained from ED & VMU medical, nursing and administrative records. Results: Our sample included 70 patients, of which 64 were referred by the CHUV ED. The victims were typically young (median age 29) males (93%). 77% of assaults occurred on the weekend between 12 PM and 4 AM, and 73% of the victims were under the influence of alcohol. 83% of the patients were punched, kicked and/or head-butted; 9% had been struck with a blunt instrument. 80% of the injuries were in the head and neck area and 19% of the victims sustained fractures. 21% of the victims were prescribed medical leave. Total ED & VMU costs averaged 1048 SFr. Conclusion: Medical staff treating this population of assault victims must be aware of the assault mechanisms and injury patterns, in particular the high probability of fractures, in order to provide adequate diagnosis and care. Associated inebriation mandates liberal use of radiology, as delayed or missed diagnosis may have medical, medicolegal and legal implications. Emergency medical services play an important role in detecting and reporting of such incidents. Centralised management of the forensic documentation facilitates referral to victim support organisations and epidemiological data collection. Magnitudes and trends of the different types of violence can be determined, and this information can be then impact public safety management policies.

The new final Clinical Skills examination in human medicine in Switzerland: Essential steps of exam development, implementation and evaluation, and central insights from the perspective of the national Working Group.

OBJECTIVE: Since 2011, the new national final examination in human medicine has been implemented in Switzerland, with a structured clinical-practical part in the OSCE format. From the perspective of the national Working Group, the current article describes the essential steps in the development, implementation and evaluation of the Federal Licensing Examination Clinical Skills (FLE CS) as well as the applied quality assurance measures. Finally, central insights gained from the last years are presented. METHODS: Based on the principles of action research, the FLE CS is in a constant state of further development. On the foundation of systematically documented experiences from previous years, in the Working Group, unresolved questions are discussed and resulting solution approaches are substantiated (planning), implemented in the examination (implementation) and subsequently evaluated (reflection). The presented results are the product of this iterative procedure. RESULTS: The FLE CS is created by experts from all faculties and subject areas in a multistage process. The examination is administered in German and French on a decentralised basis and consists of twelve interdisciplinary stations per candidate. As important quality assurance measures, the national Review Board (content validation) and the meetings of the standardised patient trainers (standardisation) have proven worthwhile. The statistical analyses show good measurement reliability and support the construct validity of the examination. Among the central insights of the past years, it has been established that the consistent implementation of the principles of action research contributes to the successful further development of the examination. CONCLUSION: The centrally coordinated, collaborative-iterative process, incorporating experts from all faculties, makes a fundamental contribution to the quality of the FLE CS. The processes and insights presented here can be useful for others planning a similar undertaking.

Déclaration et traitement des événements indésirables en médecine interne [Incident-reporting electronic-based system in internal medicine].

How to recognize, announce and analyze incidents in internal medicine units is a daily challenge that is taught to all hospital staff. It allows suggesting useful improvements for patients, as well as for the medical department and the institution. Here is presented the assessment made in the CHUV internal medicine department one year after the beginning of the institutional procedure which promotes an open process regarding communication and risk management. The department of internal medicine underlines the importance of feedback to the reporters, ensures the staff of regular follow-up concerning the measures being taken and offers to external reporters such as general practioners the possibility of using this reporting system too.
