INTRODUCTION: Positron emission tomography (PET) now plays a clear role in oncology, especially in chest tumours. We discuss the value of metabolic imaging in characterising pleural pathology in the light of our own experience and review the literature. BACKGROUND: PET is particularly useful in characterising malignant pleural pathologies and is a factor of prognosis in mesothelioma. Metabolic imaging also provides clinical information for staging lung cancer, in researching the primary tumour in metastatic pleurisy and in monitoring chronic or recurrent pleural pathologies. CONCLUSIONS: PET should therefore be considered as a useful tool in the diagnosis of liquid or solid pleural pathologies. [less ▲]Detailed reference viewed: 49 (3 ULg)

Muscle strength and anaerobic power of the lower extremities are neuromuscular variables that influence performance in many sports activities, including soccer. Despite frequent contradictions in the literature, it may be assumed that muscle strength and balance play a key role in targeted acute muscle injuries. The purpose of the present study was to provide and compare pre-season muscular strength and power profiles in professional and junior elite soccer players throughout the developmental years of 15-21. One original aspect of our study was that isokinetic data were considered alongside the past history of injury in these players. Fifty-seven elite and junior elite male soccer players were assigned to three groups: PRO, n=19; U-21, n=20 and U-17, n=18. Players benefited from knee flexor and extensor isokinetic testing consisting of concentric and eccentric exercises. A context of lingering muscle disorder was defined using statistically selected cut-offs. Functional performance was evaluated throughout a squat jump and 10 m sprint. The PRO group ran faster and jumped higher than the U-17 group (P<0.05). No significant difference in isokinetic muscle strength performance was observed between the three groups when considering normalized body mass parameters. Individual isokinetic profiles enabled the identification of 32/57 (56%) subjects presenting lower limb muscular imbalance. Thirty-six out of 57 players were identified as having sustained a previous major lower limb injury. Of these 36 players, 23 still showed significant muscular imbalance (64%). New trends in rational training could focus more on the risk of imbalance and implement antagonist strengthening aimed at injury prevention. Such an intervention would benefit not only athletes recovering from injury, but also uninjured players. An interdisciplinary approach involving trainers, a physical coach, and medical staff would be of interest to consider in implementing a prevention programme.

CONTEXT: Despite the high rate of lower limb injuries in basketball players, studies of the dominant-limb effect in elite athletes often neglect injury history. OBJECTIVE: To determine lower limb explosive-strength asymmetries in professional basketball players compared with junior basketball players and control participants. DESIGN: Cohort study. SETTING: Academic medical institution. PATIENTS OR OTHER PARTICIPANTS: 15 professional basketball players, 10 junior basketball players, and 20 healthy men. MAIN OUTCOME MEASURE(S): We performed an isokinetic examination to evaluate the knee extensor (Ext) and flexor (Fl) concentric peak torque at 60 degrees .s(-1) and 240 degrees .s(-1) and (Fl only) eccentric peak torque at 30 degrees .s(-1) and 120 degrees .s(-1). Functional evaluation included countermovement jump, countermovement jump with arms, 10-m sprint, single-leg drop jump, and single-leg, 10-second continuous jumping. Variables were compared among groups using analysis of variance or a generalized linear mixed model for bilateral variables. RESULTS: The 2 groups of basketball players demonstrated better isokinetic and functional performances than the control group did. No differences in functional or relative isokinetic variables were noted between professional and junior basketball players. Professional players with a history of knee injury failed to reach normal knee extensor strength at 60 degrees .s(-1). Knee Ext (60 degrees .s(-1)) and Fl (eccentric 120 degrees .s(-1)) torque values as well as 10-second continuous jumping scores were higher in those professional players without a history of knee injury than those with such a history. Compared with the group without a history of knee injury, the group with a history of knee injury maintained leg asymmetry ratios greater than 10% for almost all isokinetic variables and more than 15% for unilateral functional variables. CONCLUSIONS: The relative isokinetic and functional performances of professional basketball players were similar to those of junior players, with no dominant-side effect. A history of knee injury in the professional athlete, however, was reflected in bilateral isokinetic and functional asymmetries and should be considered in future studies of explosive strength.

Objectives: To investigate the cardiovascular responses to standard static assessments of strength and endurance of trunk extensor muscles. Methods: Trunk extensor performances of ten healthy men, 48.2±5.6 years, and 10 healthy women, 49±5.7 years, were assessed by means of a maximum static strength test [consisting in maximal voluntary contractions [MVC] performed with a specific dynamometer], and two static endurance tests [the Sorensen test, and a 50 percent MVC test]. Heart rate [HR], auscultatory systolic [SBP], and diastolic blood pressure [DBP] were recorded throughout the tests. Results: The MVCs induced significant increases of HR and SBP [mean peak values averaging 90 [female] to 95 [male] beats per minute and 133 [female] to 141 [male] mmHg]. The HR, SBP, and DBP values increased significantly across time throughout both endurance static tests. At the end of these tests, mean HR, SBP, and DBP reached 114 to 122 beats per minute, 172 to 185 mmHg, and 112 to 120 mmHg. Genders differed significantly with regard to holding times [longer in females], but a gender effect was only found on SBP [higher in males]. Heart rate and SBP increases were significantly higher in males than in female subjects. Conclusions: The strength test seems less demanding than expected, though our results need to be confirmed. Standard static endurance tests yield sizeable functional stress on the cardiovascular system. Our study emphasizes the need to exclude subjects with cardiac trouble from such efforts and suggests the relevance of monitoring cardiovascular parameters if tests are performed until exhaustion.

INTRODUCTION: Positron emission tomography (PET) has a clear role in oncology, particularly in thoracic disease. In the light of our experience and a revue of the literature we define precisely the role of metabolic imaging in the diagnosis of pleural pathology. BACKGROUND: In particular PET allows characterisation of malignant pleural disease and provides prognostic information in mesothelioma. Metabolic imaging provides clinical information for the staging of pulmonary cancer, in the search for a primary tumour in metastatic pleurisy and also in the follow up of chronic or recurrent pleural pathology. CONCLUSIONS: It is justified, therefore, that PET joins the diagnostic armamentarium of pleural pathology, solid or liquid. [less ▲]Detailed reference viewed: 54 (13 ULg)

Objectif Mettre au point une épreuve de quantification de l'activité physique journalière de la population générale en vue, d'une part, d'envisager des mesures préventives en matière de promotion de la santé et, d'autre part, d'établir des données normatives confrontables à celles de populations souffrant d'affections diverses (ostéo-articulatoires, rhumatologiques, chroniques, … ). Patients et Méthodes La population étudiée comporte 84 sujets volontaires sains, âgés de 20 à 80 ans et répartis en classe d'âge par décade. Le monitoring d'activité physique est réalisé durant 24 heures à partir du Sense Wear® Armband (composé d'un accéléromètre et de capteurs thermiques) porté au niveau du bras en l'absence de toute gêne particulière. Ce dispositif enregistre sur une période de 24 heures la dépense énergétique totale (Kcal), le nombre de pas, l'intensité moyenne d'effort en équivalent métabolique (MET), ainsi que la dépense énergétique réalisée à différents niveaux d'intensité d'activités physiques : 0 à 1 MET, 1 à 2 MET, 2 à 3 MET, > à 3 MET, > à 6 MET, … Les sujets sont en outre soumis au « Minnesota Leisure Time Physical Activity Questionnaire » (MLTPAQ). Résultats Nous observons une réduction significative de la dépense énergétique enregistrée durant 24 heures avec l'augmentation de l'âge. La classe d'âge 31-40 ans semble la plus dynamique comme en atteste l'intensité moyenne d'effort sur 24 h (1,7 MET), la dépense énergétique enregistrée lors d'activités supérieures à 6 MET et le nombre de pas parcourus sur 24 h. De façon originale, nous constatons que la dépense énergétique pour des activités comprises entre 0 et 1 MET augmente significativement avec l'âge alors que le phénomène inverse apparaît pour les activités supérieures à 6 MET. Un constat alarmant concerne le manque d'activités physiques actives (supérieures à 3 MET) constaté au sein de la population générale. Des corrélations significatives s'observent entre les différents paramètres enregistrés à partir du Sense Wear® Armband et diverses données issues du questionnaire MLTPAQ. Discussion L'établissement de données normatives en termes d'activités physiques journalières à partir de ce protocole original s'avère particulièrement pertinent dans le cadre du suivi fonctionnel de la population générale mais aussi de multiples populations pathologiques. Conclusion La poursuite de ces recherches dégage des perspectives en vue de la mise en place de mesures préventives en matière de promotion de la santé mais aussi dans la caractérisation du statut fonctionnel ou encore le suivi longitudinal d'un patient souffrant d'affections diverses.

The current treatment of chronic obstructive pulmonary disease (COPD) patients must comprise, in addition to an optimal pharmacological treatment, a pulmonary rehabilitation, if possible multidisciplinary, and a program of post-rehabilitation in order to maintain the outcomes. Today pulmonary rehabilitation has proved to be effective in improving dyspnoea, exercise capacity and quality of life in COPD patients, and reducing the use of health services and thus the cost. In this article we want to present pulmonary rehabilitation, its indications and results, and the way by which it is held in the CHU of Liege. [less ▲]Detailed reference viewed: 446 (14 ULg)

BACKGROUND: The intensity of the [F]fluorodeoxyglucose (F-FDG) uptake is an independent prognostic indicator in non-small cell lung cancer (NSCLC). We evaluate the relationship between the metabolic activity of the primary and the pleurisy in T4 NSCLC. METHODS: 25 patients (16 males, nine females, mean age 63 years, performance status 1) with pathology-proven, T4 NSCLC and malignant pleurisy were included. All were treated by a platinum salt-based chemotherapy regimen. Positron emission tomography (F-FDG-PET) was performed before treatment, according to a routine procedure. Regions of interest were placed over the primary and the pleural effusion on the transaxial slice showing the highest activity. The maximum pixel standard uptake values (SUVs) were calculated. Overall survival was determined by standard Kaplan-Meier survival analysis. All patients were followed up until death. RESULTS: The median survival for the entire population was 83 days (7-988). The SUVs were higher in the primary than in the pleurisy (9.2+/-5.6 and 5.5+/-2.2, respectively). There was no correlation between primary and pleurisy SUVs (r=0.3, P>0.05). The metabolic activity of the primary tumor did not predict the outcome: the median survival was 77.5 days (range 7-988) and 87 days (19-454) in the groups with SUVs lower and higher than the median value (8.7), respectively (P>0.05). By contrast, the metabolic activity of the pleurisy was significantly correlated with the median survival, which was 196 days (40-988) when the SUVs were lower than the median value (5) and 74 days (7-170) when they were higher (P=0.0096). CONCLUSION: Among patients with T4 NSCLC, those with high metabolic activity in the pleural effusion have a dire prognosis, whereas the metabolic activity of the primary fails to predict the survival.

BACKGROUND: This study evaluates the accuracy of [F]fluorodeoxyglucose positron emission tomography (F-FDG PET) imaging with semi-quantitative analysis for differentiating benign from malignant pleural exudates and for guiding the search for the primary tumour of pleural metastases. METHODS: Whole-body 18F-FDG PET was performed in 79 patients with exudative pleurisy. Standard uptake values were normalized for body weight, body surface area, lean body mass (SUVbw, SUVbsa, SUVlbm) with and without correction for blood glucose levels. Thoracoscopy was systematically performed to reveal pathological diagnosis. RESULTS: All SUVs were significantly higher in all malignant pleural diseases (n = 51) than in benign (n = 28) (P < 0.001). Moreover SUVs were greater in the pleural metastases from pulmonary primaries (n = 25) and in mesotheliomas (n = 8) than in extrathoracic primaries (n = 18) (P < 0.01) with no significant difference between lung cancers and mesotheliomas. Receiver operating curve (ROC) analysis between benign and malignant lesions showed areas under the curves that ranged from 0.803 (SUVbsa g) to 0.863 (SUVbw). The cut-off value for SUVbw which gave the best accuracy (82.3%) was 2.2. When comparing thoracic with extrathoracic primaries the highest accuracy (80.4%) was found for a cut-off value of 2.6. CONCLUSION: Semi-quantitative analysis of 18F-FDG PET imaging helps to differentiate malignant from benign pleural exudates and to distinguish between thoracic or extrathoracic primaries.
