We herein present a preliminary practical algorithm for evaluating complementary and alternative medicine (CAM) for children which relies on basic bioethical principles and considers the influence of CAM on global child healthcare. CAM is currently involved in almost all sectors of pediatric care and frequently represents a challenge to the pediatrician. The aim of this article is to provide a decision-making tool to assist the physician, especially as it remains difficult to keep up-to-date with the latest developments in the field. The reasonable application of our algorithm together with common sense should enable the pediatrician to decide whether pediatric (P)-CAM represents potential harm to the patient, and allow ethically sound counseling. In conclusion, we propose a pragmatic algorithm designed to evaluate P-CAM, briefly explain the underlying rationale and give a concrete clinical example.

BACKGROUND: In 2004, complementary and alternative medicine (CAM) was offered by physicians in one-third of Swiss hospitals. Since then, CAM health policy has changed considerably. This study aimed to describe the present supply and use of CAM in hospitals in the French-speaking part of Switzerland, and to explore qualitatively the characteristics of this offer. METHODS: Between June 2011 and March 2012, a short questionnaire was sent to the medical directors of hospitals (n = 46), asking them whether CAM was offered, where and by whom. Then, a semi-directive interview was conducted with ten CAM therapists. RESULTS: Among 37 responses (return rate 80%), 19 medical directors indicated that their hospital offered at least one CAM and 18 reported that they did not. Acupuncture was the most frequently available CAM, followed by manual therapies, osteopathy and aromatherapy. The disciplines that offered CAM most frequently were rehabilitation, gynaecology and obstetrics, palliative care, psychiatry, and anaesthetics. In eight out of ten interviews, it appeared that the procedures for introducing a CAM in the hospital were not tightly supervised by the hospital and were mainly based on the goodwill of the therapists, rather than clinical/scientific evidence. CONCLUSION: The number of hospitals offering CAM in the French-speaking part of Switzerland seemed to have risen since 2004. The selection of a CAM to be offered in a hospital should be based on the same procedure of evaluation and validation as conventional therapy, and if the safety and efficiency of the CAM is evidence-based, it should receive the same resources as a conventional therapy.

The interest in alternative medicine (AM) is growing. In the USA and Canada, studies showed that 34% of adults and 11% of children use AM. In a prospective cohort study, we investigated the interest in AM among parents of critically ill children in the paediatric Intensive Care Unit (ICU) of a university hospital. From January 1996 to April 1997, we distributed questionnaires to the parents of critically ill children. These strictly anonymous questionnaires were completed at home and returned by mail. Exclusion criteria were short ( < 1 day) or repeated hospitalizations, and insufficient proficiency of the German language. The inclusion criteria were fulfilled by 591 patients; 561 received the questionnaire (95%) and 289 (52%) were returned. Of the respondents, 70% would appreciate AM as a complementary therapy on the ICU, 23% found AM equally or more important than conventional medicine whereas only 7% regarded AM as unimportant. On the ICU, 18% used AM; surprisingly 41% of them did not discuss it with physicians or nurses. An additional 21% would have liked to use AM, but did not do so. Typically, AM-users administered AM also at home to their children and themselves. Their children were however, older.CONCLUSIONS: A substantial proportion of parents used measures of alternative medicine in the intensive care unit, or would have like to do so. However, few had the confidence to discuss this wish with the medical personal. This suggests that alternative medicine is of great interest, even on an intensive care unit. Nevertheless, discussion about alternative medicine seems to be taboo in doctor-patient relations.

Conclusion: Hospitals offering CAM in the French-speaking part of Switzerland seems to have risen since 2004. The selection of CAM to be offered in a hospital should be based on the same procedure of evaluation and validation as conventional care, and if their safety and efficiency is evidence-based, they should receive the same structural resources.

The ancient Greek medical theory based on balance or imbalance of humors disappeared in the western world, but does survive elsewhere. Is this survival related to a certain degree of health care efficiency? We explored this hypothesis through a study of classical Greco-Arab medicine in Mauritania. Modern general practitioners evaluated the safety and effectiveness of classical Arabic medicine in a Mauritanian traditional clinic, with a prognosis/follow-up method allowing the following comparisons: (i) actual patient progress (clinical outcome) compared with what the traditional 'tabib' had anticipated (= prognostic ability) and (ii) patient progress compared with what could be hoped for if the patient were treated by a modern physician in the same neighborhood. The practice appeared fairly safe and, on average, clinical outcome was similar to what could be expected with modern medicine. In some cases, patient progress was better than expected. The ability to correctly predict an individual's clinical outcome did not seem to be better along modern or Greco-Arab theories. Weekly joint meetings (modern and traditional practitioners) were spontaneously organized with a modern health centre in the neighborhood. Practitioners of a different medical system can predict patient progress. For the patient, avoiding false expectations with health care and ensuring appropriate referral may be the most important. Prognosis and outcome studies such as the one presented here may help to develop institutions where patients find support in making their choices, not only among several treatment options, but also among several medical systems.

Après la votation fédérale demandant de prendre en compte les médecines complémentaires, un consensus a été recherché dans quatorze services et unités du Centre hospitalier universitaire vaudois (CHUV). Confrontés aux données de la littérature (Plus de 2000 publications en "Evidence-based complementary medicine" depuis 1998), les soignants étaient tous surpris par l'ampleur des résultats cliniques disponibles actuellement. Tous identifiaient un besoin en formation et en informations sur le sujet. Une prise de position officielle de l'institution était aussi souhaitée, instituant l'enseignement et la recherche sur les médecines complémentaires et assurant la production d'informations rigoureuses et pertinentes pour la clinique. [Abstract] While a popular vote supported a new article on complementary and alternative medicines (CAM) in the Swiss Constitution, this assessment in 14 wards of the University Hospital of Lausanne, Switzerland, attempted at answering the question: How can CAM use be better taken into account and patients informed with more rigor and respect for their choices? Confronted with a review of the literature (> 2000 publications in "Evidence-based cornplementary medicine" since 1998), respondents declared their ignorance of the clinical data presently available on CAM. All were in favour of more teaching and information on the subject, plus an official statement from the Hospital direction, ensuring production and diffusion of rigorous and cJinically significant information on CAM.

Emergency medicine physicians aim to stabilize or restore vital functions, establish diagnosis, initiate specific treatments and adequately orientate patients. This year, new evidences have improved our knowledge about diagnostic strategy for patients with acute non traumatic headache, treatment of acute atrial fibrillation and outpatient management of acute pulmonary embolism. Reducing injection pain of local anesthetics, reducing irradiation by using alternative diagnostic tools in appendicitis suspicion, and identification of trauma patients who benefit from tranexamic acid administration are other illustrations of the efforts to improve efficacy, safety and comfort in the management of emergency patients.

The year 2011 was full of significant advances in all areas of medicine. Whether small or large issues, they all have an impact on daily practice in general internal medicine. For example, intravenous administration of diuretics in heart failure shows no benefit. But double dose may improve symptoms faster. Direct Xa inhibitors are emerging as alternative to anti-vitamin K. beta-blockers reduce overall mortality in COPD and do not worsen lung function significantly. Each year, the chief residents from the Department of internal medicine at the University hospital of Lausanne meet to share their readings. Twelve new therapeutic considerations of 2011 are reviewed here.

In 2011 several articles seemed significant for the practice of general medicine. Diagnosis of hypertension needs several measurements and may need 24-hour ambulatory blood pressure monitoring. Glycosylated hemoglobin is a reliable tool to diagnose diabetes mellitus. The ABCD2 score with neurological imaging help the triage of transient ischemic attacks. Pulmonary embolism can be treated as outpatient for low risk patients. Gluten-free diet may be tried in irritable bowel syndrome. Nitrofurantoin is a reasonable alternative for simple urinary tract infection in women, but antibiotics are not needed after drainage of an uncomplicated skin abscess. Subclinical thyroid dysfunction is a risk factor of osteoporosis in older men. Sequential use of MMSE and ACE scores is a promising approach to assess medical decision-making capacity.

Aim:Isolated limb perfusion (ILP) is a technique consisting in administrating doses of chemotherapy up to 20 times higher than via systemic route in a limb affected by melanoma or sarcoma to maximise tumour reduction. ILP is performed in <50 centres worldwide and leads to partial or complete response, however without effect on overall survival. As an alternative to amputation, it improves patient quality of life. We report our >10-year single centre experience on the role of nuclear medicine in ILP. Material and method:From 2000 to 2012, we performed 77 ILP (45 women, 32 men; aged 62±16 years) for 49 melanoma (64%), 25 sarcoma (32%) and 3 others tumors (2 desmoid tumours and 1 aggressive fibromatosis) (3%). The affected limb vascularisation is isolated from the systemic circulation (SYS) using extracorporeal circulation, and chemotherapy (usually TNF and Melphalan) is administered. Peroperatively, limb isolation and eventual leakage from ILP to SYS are monitored by continuous measurement using a gamma-probe placed over the heart (150MBq of 99mTc-human serum albumin in ILP and 4MBq in SYS). The maximum acceptable leakage to the systemic circulation is 10% (maximum tolerated systemic TNF dose). Results:In total, 47 patients (61%) had positive leaks from the ILP to SYS of 4.1±14.5% (median 1% interquartile range 0.4% to 3.2%, range 0 to 100%) and 30 patients (39%) had negative leaks from the SYS to ILP of -0.9±1.2% (median -0.5%, interquartile range -0.8% to -0.2%, range -4.8% to -0.1%). In only 2 patients (2.6%), leaks >10% were observed leading to interrupting ILP. Conclusion:Nuclear Medicine has a crucial role for the safety and quality of ILP in monitoring leakage peroperatively and help deciding whether the procedure should be interrupted to minimize systemic toxicity.

Assessment of image quality for digital x-ray mammography systems used in European screening programs relies mainly on contrast-detail CDMAM phantom scoring and requires the acquisition and analysis of many images in order to reduce variability in threshold detectability. Part II of this study proposes an alternative method based on the detectability index (d') calculated for a non-prewhitened model observer with an eye filter (NPWE). The detectability index was calculated from the normalized noise power spectrum and image contrast, both measured from an image of a 5 cm poly(methyl methacrylate) phantom containing a 0.2 mm thick aluminium square, and the pre-sampling modulation transfer function. This was performed as a function of air kerma at the detector for 11 different digital mammography systems. These calculated d' values were compared against threshold gold thickness (T) results measured with the CDMAM test object and against derived theoretical relationships. A simple relationship was found between T and d', as a function of detector air kerma; a linear relationship was found between d' and contrast-to-noise ratio. The values of threshold thickness used to specify acceptable performance in the European Guidelines for 0.10 and 0.25 mm diameter discs were equivalent to threshold calculated detectability indices of 1.05 and 6.30, respectively. The NPWE method is a validated alternative to CDMAM scoring for use in the image quality specification, quality control and optimization of digital x-ray systems for screening mammography.
