Abstract
AIM The aim of this study was to assess the feasibility and relevance of determining ankle brachial index (ABI) using an automatic blood pressure device in subjects seen for their annual routine examination by occupational physicians and to compare the obtained ABI with the Framingham score. PATIENTS AND METHODS Sixteen physicians randomly recruited 634 subjects in 12 departments of occupational medicine. Subjects aged between 40 and 60 years underwent a determination of ABI using an OMRON HM 722 device and the analysis of Framingham score. Other analysed variables were: sex, age, smoking habit, hypertension, diabetes, hypercholesterolemia, glycaemia, total cholesterol, HDL and LDL cholesterol and triglycerides levels. RESULTS Mean age of the population studied was 48.1 ± 6.0 years; 73% were men, 36% were smokers, 14% had hypertension, 3.3% diabetes and 22% hypercholesterolemia. Biochemical values were glycaemia 0.90 ± 0.30 g/l, total cholesterol 2.10 ± 0.4 g/l, HDL cholesterol level 0.50 ± 0.20 g/l, LDL cholesterol level 1.30 ± 0.40 g/l, and triglycerides 1.40 ± 1.0 g/l. Mean ABI were 1.1 ± 0.1 in both legs. Mean Framingham score was 8.2 ± 5.4%. Only 20 subjects (3%) had an ABI < 0.90. No relation was found between pathological ABI and Framingham score (abnormal ABI : 9.9 ± 5.5 vs. normal ABI : 8.2 ± 5.4, NS). CONCLUSION The determination of ABI using a simple commercially available automatic blood pressure device is feasible and easy to implement by preventive or general physicians in all kinds of routine examinations. In our opinion automatic ABI very easy and quick to determine provides, in addition to Framingham score, a simple and useful tool to detect subjects at high cardio-vascular risk.

Abstract
This review describes the ballistic quality assurance for stereotactic intracranial irradiation treatments delivered with Gamma Knife® either dedicated or adapted medical linear accelerators. Specific and periodic controls should be performed in order to check the mechanical stability for both irradiation and collimation systems. If this step remains under the responsibility of the medical physicist, it should be done in agreement with the manufacturer's technical support. At this time, there are no recent published guidelines. With technological developments, both frequency and accuracy should be assessed in each institution according to the treatment mode: single versus hypofractionnated dose, circular collimator versus micro-multileaf collimators. In addition, "end-to-end" techniques are mandatory to find the origin of potential discrepancies and to estimate the global ballistic accuracy of the delivered treatment. Indeed, they include frames, non-invasive immobilization devices, localizers, multimodal imaging for delineation and in-room positioning imaging systems. The final precision that could be reasonably achieved is more or less 1mm.

Abstract
We describe an outbreak of human metapneumovirus (hMPV) which occurred in July-September 2010 at a community hospital in the East of England. Based on the medical and nursing records, cases were retrospectively defined as suspected if they had had an influenza-like illness (ILI), and probable if they had had an ILI and an epidemiological link to a laboratory-confirmed case. Of a total of 17 symptomatic inpatients, five were classified as probable cases, five were laboratory confirmed and seven were suspected. The attack rate was 29.4% for confirmed and probable cases combined. The median age of symptomatic inpatients was 85 years-old (range 68-96) and the majority (16/17) of symptomatic inpatients had an underlying medical condition. Control measures introduced appeared to restrict further exposure of susceptible patients to infection although modelling suggested that up to four of 10 confirmed and probable cases (40%) could have been prevented through more timely diagnosis and recognition of an outbreak. These findings suggest that there should be increased awareness of hMPV infection within healthcare settings, particularly when the population at risk has a high prevalence of underlying co-morbidities.

Abstract
BACKGROUND The number of patients with pacemakers has been increasing and a large number of them will present with chest pain or symptoms suggesting angina pectoris. Myocardial ischemia and presence of coronary artery disease are difficult to detect and assess by noninvasive methods in patients with a pacemaker; the electrocardiogram (ECG) at rest and during exercise is usually very difficult to analyze in terms of ischemia or even presence of an acute myocardial infarction. HYPOTHESIS To detect significant coronary stenosis in patients with previously implanted pacemakers, we tested a new stress echocardiography method using incremental ventricular pacing by already implanted pacemakers. METHODS We studied prospectively 25 consecutive patients who underwent stress echocardiography with increasing ventricular pacing up to either 85% of the age-predicted maximal heart rate or chest pain. Positive tests were defined by new hypokinesia or worsening of a preexisting alteration in wall motion in at least two adjacent territories. All patients underwent coronary angiograms to define the presence and severity of coronary stenoses. RESULTS Among the 25 tests, 11 (44%) were stopped for chest pain. 1 (4%) for moderate discomfort, 1 (4%) for a drop in blood pressure, and the target pacing rate was achieved in the tests of the remaining 12 patients (48%). There were no complications. Thirteen patients had significant stenoses. In 10 cases, stress echocardiography was a true positive test with respect to coronary angiography. There were 11 true negative, 1 false positive, and 3 false negative tests. The sensitivity was 77%, specificity was 90%, the positive predictive value was 91%, and the negative predictive value 79%. The accuracy was 84%. CONCLUSIONS This new stress echocardiography method appears feasible, easy, safe, and effective for detection of significant coronary stenoses in patients with pacemakers.

Abstract
We have developed an original Kelvin probe system using an ultrasonic stepped horn sonotrode. This actuator is optimized in order to maximize the velocity of the tip end, and hence to increase the Kelvin current detected. Such development is essential to improve surface potential measurements at small spatial scale.

Abstract
BACKGROUND Leukocyte scintigraphy is a noninvasive investigation to assess inflammation. We evaluated the utility of labeled leukocytes to detect small bowel inflammation and disease complications in Crohn's disease and compared it to whole small bowel enteroscopy and laparotomy findings. METHODS Scintigraphy with technetium-99m exametazime-labeled leukocytes was prospectively performed in 48 patients with Crohn's disease a few days before laparotomy; 41 also had an intraoperative small bowel enteroscopy. The same procedures were performed in 8 control patients. Independent grading of scans was compared with the results of enteroscopy and with surgical, histopathologic, and clinical data. RESULTS In the 8 control patients leukocyte scan, endoscopy, and histopathology were all negative for the small bowel. In patients with Crohn's disease and small bowel inflammation seen at enteroscopy and/or laparotomy (n = 39) the scan was positive in 33. In 8 patients without macroscopic small bowel inflammation, the scan was positive for the small bowel in 3 patients; at histology, 2 of 3 had inflammation. When combining results for patients and controls, the sensitivity of leukocyte scan for macroscopically evident small bowel inflammation was 0.85, specificity 0.81, accuracy 0.84, positive predictive value 0.92, and negative predictive value 0.68. Scintigraphy detected inflammatory lesions not known before laparotomy in 16 of 47 (34%) Crohn's disease patients and showed uptake in 25 of 35 (71%) bowel strictures. It was diagnostic regarding 4 of 8 abscesses and 9 of 15 fistulas. In 6 patients (13%) lesions first demonstrated by leukocyte scintigraphy were treated during the surgery performed. CONCLUSIONS Leukocyte scintigraphy reliably detects small bowel inflammation in Crohn's disease. It gives additional information on the presence of inflammatory lesions in a fraction of patients planned for surgery.

Abstract
PURPOSE To analyse a new technique for prostate brachytherapy with permanent Iodine implants characterized by the use of a seed projector after a 3D dosimetric peroperative treatment planning (FIRST technique). PATIENTS AND METHOD 395 patients have been treated in France with this technique in six radiotherapy centres between November 2002 and December 2005 for a localized prostate cancer. RESULTS Thirteen patients (3.3%) developped a urinary retention, and respectively 7.8 and 26.5% an acute RTOG grade 3 and 2 toxicity. The 6-weeks IPSS score was equal or lower to 15 in 73% with a 11 median IPSS value. A failure of the loading with the seed-projector, leading to a manual loading of the seeds, occurred in 9 patients (2.3%) in two centres, directly related to the loading procedure with the seed-projector in 5 cases. The median duration of the procedure was reduced by 30 minutes for the patients treated in 2005. CONCLUSIONS This multicenter study establishes the feasibility of the routine use of a seed projector for permanent iodine 125 prostate implants with an initial tolerance similar to the best results published for other implants techniques.

Abstract
BACKGROUND Contraceptive use is a complex issue and several studies have been conducted in an effort to understand user behaviour. It is of interest to explore the representations of professionals who give advice on contraception, since their views could have an impact on contraceptive use. METHODS Individual in-depth interviews of 65 healthcare professionals likely to provide contraceptive advice to patients at a Swiss maternity unit. RESULTS 83% of healthcare professionals interviewed were favourable to contraception in general while being highly critical of its practical efficacy. The methods most often spontaneously cited were oral contraceptive pills, male condom, intrauterine devices and hormonal implants. Theoretically, all methods should be proposed during contraceptive counselling but in practice interviewees have different social representations of user groups and associate them with specific contraceptive methods. Personal experience appears to play a bigger role than scientific knowledge. CONCLUSIONS The counsellor's social representations probably play an important role in determining user behaviour. These representations should be taken into consideration in the training of healthcare professionals in this field.

Abstract
We report the case of a 45-year-old man with HCV treated with pegylated interferon-alpha/ribavirin, in whom fatal cardiomyopathy occurred. Cardiomyopathy is a rare complication of high dose of standard interferon but has never been reported with pegylated interferon. The relationship between pegylated interferon-alpha/ribavirin and the development of cardiomyopathy is highly probable for the following reasons: (1) a cardiologist consultation with specific investigations had been performed before treatment excluding a pre-existing cardiomyopathy; (2) symptoms of advanced dilated cardiomyopathy appeared immediately after the end of treatment; (3) other causes of cardiomyopathy have been ruled out. In all except one of the 21 reported cases with standard interferon, cardiomyopathy was reversible. In our patient, fatal cardiomyopathy occurred with a usual dose of pegylated interferon-alpha. Clinicians should be aware of this potential complication when evaluating the ratio benefit/risk of treatment in patients with chronic hepatitis C infection.
