Introduction : The Victorian Institute of Sports Assessment– Achilles (VISA-A) was designed to evaluate the clinical severity of Achilles tendinopathy. It has been developed in English and therefore is not adapted for French-speaking patients. Although this questionnaire has already been translated into different languages but not in French. French is spoken by most than 275 millions of people and is one of the 2 official languages of the International Olympic Committee, and one of the 6 official languages and one of the 2 working languages of the United Nation Organisation. The aim of this study was to translate this questionnaires into French and to study its reliability and validity. Methods : The questionnaire was translated into French (VISA-AF) according to the "guidelines for the process of cross-cultural adaptation of self-report measures" using six steps: translation, synthesis, back translation, expert committee review, pretesting, and appraisal of the adaptation process by the expert committee. Once the final versions obtained, several psychometric proprieties such as test-retest fidelity, internal coherence, construct validity and floor and ceiling effects were evaluated. We recruited 116 subjects who were distributed in 3 groups: pathological patients (n=31), at risk athletes (n=63), healthy people (n=22). Results : The questionnaire was approved by the expert committee after the pre-final version test. On a scale ranging from 0 (theoretical minimum) to 100 (asymptomatic subject), the average scores of the VISA-PF obtained were 59 (± 18) for the pathological group, 99 (± 1) for the healthy group and 94 (± 7) for the sports-risk group. The VISA-A-F shows excellent reliability. The VISA-AF shows low correlations with the divergent sub-scales of the SF-36 and moderate correlations with the convergent sub-scales of the SF-36. No floor and ceiling effects were detected during the evaluation of the two questionnaires. Conclusion : The French versions of the VISA-A is equivalent to its original version and is reliable and valid questionnaire for French speaking patients with Achilles tendinopathy. [less ▲]

INTRODUCTION: Jumper's knee is a frequent chronic overuse syndrome of the upper part of the patellar tendon. Platelets contain lots of growth factors which could enhance the healing process of tendons. METHODS: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months after the infiltration, using a 10--point Visual Analogic Scale, clinical examinations with a pressure algometer, algofunctional scores (IKDC and VISA--P), functional assessments (isokinetic and optojump evaluations) and imagery (ultrasounds and MRI). The PRP was obtained with an apheresis system (COM.TEC, Fresenius). Six millilitres of PRP were injected without local anaesthetic. One week after infiltration, patients started a standardised sub--maximal eccentric reeducation. RESULTS: Pain during daily activities significantly decreased with time. During functional evaluation, it decreased as well, but without significant functional improvement. No improvements in the imagery measurements were observed. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. CONCLUSION: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol can improve symptoms of chronic jumper's knee in patients non--responsive to classical conservative treatments.

Introduction: Infiltration of Platelet-Rich Plasma (PRP) may be considered as a recent therapeutic option for chronic tendinopathies. The aim of this study is to evaluate the clinical status and the return to sports activities in patients with chronic upper patellar tendinopathies. Material and methods : Twenty subjects with chronic upper patellar tendinopathy benefited from 1 infiltration of PRP. The follow-up (up to 1 year) was assessed by means of a Visual Anologue Scale (VAS), the International Knee Documentation Committee (IKDC) form and the Victorian Institute of Sport Assessment (VISA-P) score. Moreover, subjects had to answer an information questionnaire concerning their life and sports activities. Results : Seventy percents of the patients reported a favourable evolution with decrease of pain, and returned to sports activities. With time, VAS dropped significantly and both IKDC and VISA-P scores improved also significantly. Conclusion : This study confirms that a local injection of PRP coupled with a program of eccentric rehabilitation for treating a chronic jumper's knee, improves pain symptoms and the functionalities of the subjects’ knee up to 1 year after injection.

This study examines the share and allocation of household expenditure in health financing, as presented by the National Health Account figures. These figures are based on a national survey carried out in 2010 among 11,000 households, 2,200 people living with HIV/AIDS, 183 institutions, 42 mutual funds, 18 companies and using the balance sheets of 1,300 companies. Total household health expenditure per capita per year amounted to U.S. $ 4.50. Routine health expenditure is covered by the households (40%) and international cooperation (45%) through direct payment without cost sharing (93.7%). A hospital stay is warranted in case of nutritional deficiencies (34%), malaria (12%) and mental disorders (10%). 82% of outpatient care is related to malaria (71%) and mental disorders (12.5 %). In conclusion, the observation that 71.58% of hospitals expenditure, 96.49% of ambulatory care centres expenditure, 98.48% of medical and diagnosis laboratories expenditure, 72.42% of pharmacies expenditures come from households’ out of pocket expenses calls for the establishment of solidarity mechanisms in the health sector. Outpatient malaria care consumes as much as 71% of household expenditure, and we therefore need to strengthen prevention, treatment and focus on monitoring progress. The fact that nutritional deficiencies are the leading cause of people seeking hospital care suggests that efforts are needed to improve their living conditions of households. Mental disorders are the third leading cause of hospital recourse and this pathology should therefore be included in the minimum and supplementary package of activities. [less ▲]

Analysis of national health insurance accounts in the Democratic Republic of Congo (DRC) clearly shows the importance of international sanitary aid, particularly for the funding of general referral hospitals, the management of inpatients with AIDS, administration of health zones and funding of preventive care providers. It The targeted changes described in this article could possibly optimize the efficiency of international aid for the DRC population, mainly for disorders considered to be a health care priority (i.e. malaria, AIDS, tuberculosis) as well as in the fight against malnutrition. Recommendations target the implementation of procedures for control of food chain security, changes in lifestyle and dietary habits of the population but also comprise extensive restructuring of the health care administration. A dramatic change of the structure in charge of drug distribution as well as eradication of the transfer of part of public health structure income to public health administrative personnel could result in the allocation of significant funds to the fight against the most important diseases. Better collaboration between the various departments in charge of health care professional training, together with enhanced responsibility of health care personnel is essential. Independent and respected non-governmental organizations should be involved in an audit process, targeting all aspects of the current DRC health system. Eventually, in an equal opportunity perspective, taking into consideration the very high degree of poverty of DRC inhabitants, implementation of health insurance programmes, use of generic drugs and generalization of micro-credit initiatives should also be implemented.

BACKGROUND: Besides magnetic resonance imaging, dual energy X-ray absorptiometry (DXA) seems the most reliable tool to evaluate body composition and is often considered as the gold standard in clinical practice. Bioelectrical impedance analysis (BIA) could provide a simpler, portative, and less expensive alternative. Because the body composition assessment by BIA is device-dependent, the aim of this study was to appraise the concordance between the specific bioelectrical impedance device InBody S10 and DXA for the body composition evaluation. METHODS: Body composition, included appendicular lean mass divided by height squared (ALM/ht2) was measured by DXA (Hologic QDR Discovery device) and by BIA (InBody S10 Biospace device). Agreement between tools was assessed by means of the Bland Altman method and reliability was determined using the IntraClass Coefficient (ICC). ICC was also computed to assess the reliability of the test-retest performed by the same operator or by two different ones. RESULTS: A total of 219 subjects were enrolled in this study (mean age: 43.7 +/- 19.1 years old, 51.6% of women). For the ALM/ht2, reliability of the test-retest of the BIA was high with an ICC of 0.89 (95%CI: 0.86-0.92) when performed by the same operator and an ICC of 0.77 (95%CI: 0.72-0.82) when performed by two different operators. Agreement between ALM/ht2 assessed by DXA and BIA was low (ICC = 0.37 (95%CI: 0.25-0.48)). Mean ALM/ht2 was 9.19 +/- 1.39 kg/m2 with BIA and 7.34 +/- 1.34 kg/m2 with DXA, (p < 0001). A formula developed using a multiple regression analysis, and taking into account muscle mass assessed by BIA, as well as sex and body mass index, explains 89% of the ALM/ht2 assessed by DXA. CONCLUSIONS: Although our results show that the measure of ALM/ht2 by BIA is reliable, the agreement between DXA and BIA is low. Indeed, BIA seems to overestimate ALM/ht2 compared to DXA and, consequently, it is important to use an adapted formula to obtain measurement of the appendicular lean mass by BIA close to that measured by DXA.

Urolithiasis is a common condition, with a prevalence of 10% and a male/female ratio above 1 according to large national series. Various types of urinary stones have been described upon their mineral content and/or their morphology. Hence, a combined morpho-constitutional (M-C) classification has been proposed. In order to detail the prevalence of urolithiasis in general and of each M-C type in particular upon age and gender in Belgium, we retrospectively studied the database of a reference center for urolithiasis analysis. Between 2010 and 2013, 2195 stones were characterized. We excluded 45 nonbiological stones and 281 stones, which originated from outside the study zone. Among 1869 stones,1293 (69.2%) affected men. Prevalence peak of urolithiasis was observed between 50–60 years of age in both genders. The M-C analysis was available for 1854 stones (99.2%): multiple morphological types were concomitantly identified in 49.3%. In the whole population, the main mineral constituent was whewellite (54.4%), mainly organized as type Ia (94%). Weddellite was found in 19.8%, with an equal distribution between types IIa and IIb. Uric acid was the 3rd most frequent constituent in man, with a similar distribution between IIIa and IIIb. Phosphate was uncommon in man (8.2%), but frequent in woman (26.6%) with a type IVa1 organization. Prevalence of M-C types changes with aging, i.e. decrease of weddellite and increase of whewellite and uric acid in both genders. This retrospective analysis of a single-center database of urinary stones helps characterize the M-C epidemiology of urolithiasis in Belgium. [less ▲]

Food allergy is a major public health issue. However, no regulatory measures exist when allergens are present at trace levels and the different risk components are poorly described. Thus, knowledge on exposure components such as the allergens present in foods and the consumption behaviour of allergic consumers and models to estimate the related risk need to be enriched. Mirabel proposes for the first time studying each risk component using an integrated approach in order to improve the quality of life of the allergic population. Field surveys were conducted in order to fill in the current gaps in unintentional allergen traces in food, allergic consumers’ food behaviour, threshold doses of allergic reaction, allergy symptoms and severity. The aim is also to propose methodological and operational tools to quantify allergic risk, to test management scenarios and to produce a cost/benefit analysis. Medical data on the peanut allergies of 785 patients were collected in the MIRABEL survey and 443 patients answered the food consumption questionnaire. The population surveyed was mostly paediatric – 86% were children under 16 years of age, with a high percentage of males (60%). This project will generate tangible results on peanut allergen exposure and risk which could be used in future risk assessment work and particularly to provide science-based guidance to set up concentration limits for peanut traces on packages.
