Background: Recommendations are available for assessment criteria for safe return-to-play (RTP) after a lateral ankle sprain. However, their current use among physicians is unknown. Methods: French-speaking physicians in Belgium, France and Switzerland were asked to complete an online survey and report their clinical assessment of selected RTP criteria. Results:The respondent sample (n = 109) included physicians with and without Sports Medicine education, varied level of experience and proportion of athletes in their practice population. Pain was the most selected criterion for safe RTP (90% of physicians), followed by ability to engage in functional tasks (82%), functional instability (73%), range of motion (61%), proprioception (47%), mechanical instability (39%), strength (38%) and swelling (31%). A low proportion of physicians use quantitative measures to assess these criteria (between 4% and 53%). Conclusions: A large proportion of physicians consider the recommended criteria for RTP decisions. However, physicians do not frequently use quantitative measures. [less ▲]

Background. After a period of coma, a proportion of individuals with severe brain injury remain in an altered state of consciousness before regaining partial or complete recovery. Individuals with disorders of consciousness (DOC) classically receive hydration and nutrition through an enteral feeding tube. However, the real impact of the level of consciousness on an individual’s swallowing ability remains poorly investigated. Objective. We aimed to document the incidence and characteristics of dysphagia in DOC individuals and to evaluate the link between different components of swallowing and the level of consciousness. Methods. We analyzed clinical data on the respiratory status, oral feeding and otolaryngologic examination of swallowing in DOC individuals. Univariate and multivariate logistic regression was used to analyse the association of components of swallowing and participant groups (i.e., unresponsive wakefulness syndrome [UWS] and minimally conscious state [MCS]). Results. We included 92 individuals with DOC (26 UWS and 66 MCS). Overall, 99% of the participants showed deficits in the oral and/or pharyngeal phase of swallowing. As compared with the MCS group, the UWS group more frequently had a tracheostomy (69% vs 24%), with diminished cough reflex (27% vs 54%) and no effective oral phase (0% vs 21%). Conclusion. Almost all DOC participants had severe dysphagia. Some components of swallowing (i.e., tracheostomy, cough reflex and efficacy of the oral phase of swallowing) were related to consciousness. In particular, no UWS participant had an efficient oral phase, which suggests that its presence may be a sign of consciousness. In addition, no UWS participant could be fed entirely orally, whereas no MCS participant orally received ordinary food. Our study also confirms that objective swallowing assessment can be successfully completed in DOC individuals and that specific care is needed to treat severe dysphagia in DOC. [less ▲]

Purpose There has been much debate regarding the use of intra-articular injections of platelet-rich plasma (PRP) as symptomatic treatment for knee osteoarthritis. The objective of this consensus was to develop guidelines for PRP injections in knee osteoarthritis according to the French National Authority for Health recommendations. Methods Fifteen physicians from different French-speaking countries (10 rheumatologists, 4 specialists in rehabilitation and sports medicine and 1 radiologist) were selected for their expertise in the areas of PRP and osteoarthritis. A comprehensive literature review was conducted on Medline including all published therapeutic trials, open studies, meta-analysis and systematic reviews focusing on the effects of PRP in knee OA, as well as fundamental studies concerning the characteristics of the various types of PRP and their mechanisms, indexed before April 2019. Using the method recommended by the French National Authority for Health inspired by the Delphi consensus process, 25 recommendations were finally retained and evaluated. The recommendations were classified as appropriate or not appropriate, with strong or relative agreement, or uncertain if a consensus was not achieved. Results Among the 25 recommendations selected, the main ones are the following: (1) Intra-articular injections of PRP are an effective symptomatic treatment for early to moderate knee osteoarthritis. This recommendation was considered appropriate with a relative agreement (Median = 8; rank = 6–9). Level of evidence 1A. (2) A PRP treatment sequence in knee osteoarthritis may include 1–3 injections. This recommendation was considered appropriate with a strong agreement (Median = 9; rank = 7–9). Level of evidence 1A. (3) Leucocytes-poor PRP should be preferred in knee osteoarthritis. This recommendation was considered appropriate with a relative agreement (Median = 8; rank = 5–9). Level of evidence 5. (4) Intra-articular PRP knee injections should be performed under ultrasound or fluoroscopic guidance. This recommendation was considered uncertain with no consensus (Median = 8; rank = 3–9). Level of evidence 5. (5) PRP should not be mixed with an anesthetic or intra-articular corticosteroid. This recommendation was considered appropriate with a relative agreement (Median = 9; rank = 6–9). Level of evidence 5 Conclusion Those 25 recommendations should standardize and facilitate the use of IA PRP injections, which are considered by experts as an effective treatment especially in early or moderate knee OA. Although a strong or relative agreement from the experts was obtained for most of the recommendations, many of them had a very low level of evidence (Level 5) and were principally based on the clinical experience of the experts.

The aim of this study was to describe the effects of a 64.2 km ultra-trail on the biomarkers of muscle damage, inflammation and oxidative stress, and compare the results observed with an ECG and an echocardiogram, both performed before and after the race. Thirty-three ultra-trail volunteers (45.8 ± 8.7 years old) were enrolled in our study. Three blood tests were drawn from each runner, one just before (TPRE), one just after (TPOST) and the last 3 h after the end of the race (TPOST3h). All the markers increased. The maximum concentrations observed were at TPOST3h and were significant (p<0.001) for creatine kinase, creatine kinase isoform MB, high-sensitivity C-reactive protein, uric acid and for the ratio of reduced glutathione to oxidised glutathione. However, in the case of myoglobin, high-sensitive troponin T, N-terminal pro-brain natriuretic peptide, oxidised glutathione, myeloperoxidase, cystatin C and creatinine, the most significant increases were at TPOST (p<0.001). Modifications were observed in the medical imaging using echocardiography such as reduction of left ventricule end-sytolic and diastolic volumes and left ventricular global longitudinal strain. ECG showed electrical criteria for left ventricular hypertrophy and incomplete right bundle branch block after the race. Endurance races cause significant physiological stress to the body that can be measured by the increase of different biomarkers. From a laboratory perspective, it is important to take into account the possible exercise performed previous to the testing to avoid a misinterpretation of the results. From a training perspective, due to these increases in biomarkers, it is recommended that runners wait at least 72 h after an ultra-trail before subsequent training. In addition a transient impairment of ventricular function due to dehydration were observed. [less ▲]

The Wingate Anaerobic Test (WAnT) and isokinetic fatigability protocols are mainly used to evaluate the anaerobic power of athletes for whom jumping is a predominant action in their sport. Nevertheless, the testing protocol must be as close as possible to the activity pattern of the sport to be valid. Therefore, for these athletes, the test should consist of repetitions of jumps that are task-specific. Our aim was to propose a new jumping protocol allowing for specific assessment of fatigue, to examine its absolute and relative reliability and to determine its ideal duration. Twenty male volleyball performed fifty countermovement jumps (CMJ) at a rate of 33 jumps per minute on two occasions, with seven days recovery between each session. Jump height was computed for each CMJ using a 3D optoelectronic system, which was subsequently added to determine cumulative performance after 10, 15, 20, 25, 30, 35, 40, 45 and 50 repetitions. Reliability of the average jump height was not affected by the lengthening of the protocol and was high for all considered durations (ICC > 0.94; SEM < 5%). A decrease in performance was directly and proportionally related to the duration of the fatigability protocol. Measuring average jump height during a protocol involving 25 CMJ at the rate of 33 jumps per minute appears to represent the best compromise between reliability, induced fatigue and physiological considerations. Moreover, until 25 repetitions, the partial sums by five repetitions can and should be used to further explore the subject's performance during the test. [less ▲]

Background: After a coma, patients with severe brain injury may present disorders of consciousness (DOC). A substantial proportion of these patients also suffer from severe dysphagia. Assessment of and therapy for swallowing disabilities of patients with DOC are essential because dysphagia has major functional consequences and comorbidities. Dysphagia evaluation in patients with DOC is impeded by the lack of adapted tools. The first aim of this study was to create a new tool, the SWallowing Assessment in Disorders Of Consciousness (SWADOC), and propose a validation protocol. The SWADOC was developed to help therapists assess factors related to swallowing in patients with DOC. The second aim was to investigate the relationship between patients' level of consciousness and SWADOC items and scores. Method/Design: In this multicenter prospective cohort, 104 patients with DOC will be tested three times over five consecutive days with the SWADOC. Statistical analyses will focus on the reliability and validity of the SWADOC, especially the intrarater and interrater reliability, internal consistency, measures of dispersion, and concurrent validity with the Facial Oral Tract Therapy Swallowing Assessment of Saliva (FOTT-SAS). The level of consciousness will be assessed with the Simplified Evaluation of CONsciousness Disorders (SECONDs) and the Coma Recovery Scale-Revised (CRS-R). Discussion: The assessment of swallowing abilities among patients with DOC is the first necessary step toward the development of a customized dysphagia care plan. A validated scoring tool will be essential for clinicians to better assess dysphagia in patients with DOC and document the evolution of their disorders. [less ▲]

X-linked hypophosphatemia (XLH) is the most common genetic form of hypophosphatemic rickets and osteomalacia. In this disease, mutations in the PHEX gene lead to elevated levels of the hormone fibroblast growth factor 23 (FGF23), resulting in renal phosphate wasting and impaired skeletal and dental mineralization. Recently, international guidelines for the diagnosis and treatment of this condition have been published. However, more specific recommendations are needed to provide guidance at the national level, considering resource availability and health economic aspects. A national multidisciplinary group of Belgian experts convened to discuss translation of international best available evidence into locally feasible consensus recommendations. Patients with XLH may present to a wide array of primary, secondary and tertiary care physicians, among whom awareness of the disease should be raised. XLH has a very broad differential-diagnosis for which clinical features, biochemical and genetic testing in centers of expertise are recommended. Optimal care requires a multidisciplinary approach, guided by an expert in metabolic bone diseases and involving (according to the individual patient’s needs) pediatric and adult medical specialties and paramedical caregivers, including but not limited to general practitioners, dentists, radiologists and orthopedic surgeons. In children with severe or refractory symptoms, FGF23 inhibition using burosumab may provide superior outcomes compared to conventional medical therapy with phosphate supplements and active vitamin D analogues. Burosumab has also demonstrated promising results in adults on certain clinical outcomes such as pseudofractures. In summary, this work outlines recommendations for clinicians and policymakers, with a vision for improving the diagnostic and therapeutic landscape for XLH patients in Belgium. [less ▲]

Goalkeepers are important players in a soccer team. Their purpose is to not take a goal. They are the only ones authorized to grab the ball with their hands. They have different physical characteristics and abilities from other players. They cover approximately half of the distance of the outfield players. They have few decisive actions (2 to 10) but it is at a high intensity (jumps, dives, sprints). Goalkeepers are different players, so they are exposed to different types of injuries. The incidence of injury is lesser than other, 4,6 per 1000 hours of soccer exposure against 8 for the out fields players. Injuries in the upper extremity are 5 times more frequent in goalkeepers than other, with longer days of absence. Appropriate training combined with specific prevention programs should contribute to the reduction of injuries and the optimization of their soccer potential. [less ▲]

Androgenic alopecia is a genetically determined and leads to a progressive hair loss of the vertex, affecting both men and women. It is related to an important psychological and social distress. Medical therapies include topical minoxidil, oral 5α-reductase inhibitors and oestroprogestative drugs with anti-androgen effects for women. The surgical option is autograft hair transplantation. Recently, phototherapy with low-level energy lasers became available. All these treatments may present adverse effects and their effectiveness is questionable. Subcutaneous injections of autologous platelet-rich plasma into the scalp represent an interesting alternative treatment for androgenetic alopecia, as monotherapy or as an adjuvant treatment. The methodology, the possible mechanisms of action and some initial clinical results of this treatment are presented. [less ▲]

Introduction: Developed in 2015, the VISA-G is the first Patient Reported Outcome Measure (PROM) tool specifically designed to measure the severity of disability associated with greater trochanteric pain syndrome. There is currently no French version of the VISA-G questionnaire. Objective: The purpose of this work was to translate the VISA-G questionnaire into French (VISA-GF) and to test its psychometric performances. Design: Cross-sectional study, validation study. Setting: Clinics in Liège, Belgium and in France. Patients: Participants suffering from greater trochanteric pain syndrome and control asymptomatic participants. Intervention: Not applicable Main outcome: French translation of the VISA-G and psychometric performances of the questionnaire tested using internal consistency, construct validity and test-retest reliability with a seven-day interval. Results: The eight items of the VISA-G questionnaire were translated without any difficulties. 106 participants (median age 53 (58-64) years old, 65 women (61.3%)) were included in the psychometric validation study. The questionnaire discriminates well between pathologic (n=52) and asymptomatic participants (n=54). Moreover, we found a good internal consistency and excellent test-retest reliability for the VISA-GF questionnaire. We also confirmed the construct validity and did not find any floor or ceiling effects. Conclusions: The VISA-GF has been shown to be a valid and reliable way to measure the severity of disability associated with greater trochanteric pain syndrome in French speaking participants.

BACKGROUND: Functional ankle instability affects 20-40% of individuals who have already suffered from a sprain. Such dysfunctions are difficult to diagnose. Therefore, the information provided by self-administered questionnaires is essential. Thus, the Ankle Instability Instrument (AII) was developed and initially validated in English. Our goal is to create a French version of the instrument, named AII-F, by scrupulously respecting the cultural adaptation phases and to make sure the new instrument has good psychometric properties. METHODS: International recommendations have been rigorously followed for the cultural adaptation and the French-translation phase. Six steps are recommended: I) two initial translations from English to French; II) synthesis of the two versions; III) back-translations from French to English; IV) comparisons between the back-translations and the original questionnaire by the expert committee; V) pretest; and VI) approval of the final French version of the AII. In order to validate this French-translation, 91 subjects suffering from ankle instability matched to 91 healthy subjects were asked to complete the AII-F. The Short Form Health Survey (SF-36) was used as a comparative questionnaire as well as the French Cumberland Ankle Instability Tool (CAIT-F). The psychometric properties of the questionnaire were evaluated by determining the test-retest reliability after a 10-14-day interval, the internal consistency, construct validity, and the floor/ceiling effects. RESULTS: The French-translation did not pose a problem and could be validated by the expert committee. The AII-F showed a very good test-retest reliability for the total score, with an Intra Class Coefficient of 0.983. The internal coherence is high with an alpha coefficient of Cronbach of 0.861. The association of the AII-F with the CAIT-F was high, for the summary of the physical component of the SF-36, meaning a great convergent validity. The other subscales of the SF-36 (mental health) were weakly correlated with the AII-F, reflecting good divergent validity. An optimal cut-off score was obtained to dissociate pathological patients from healthy subjects: when the subject responded to "yes" 5 times or more, he is considered, with a very high degree of confidence, to be pathological. CONCLUSION: The AII-F is reliable and valid for evaluating and measuring functional ankle instability. [less ▲]
