[more ▼] 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.

[more ▼] 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.

[more ▼] 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.

[more ▼] 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.

[more ▼] 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.

[more ▼] 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.

En particulier, une faiblesse des muscles respiratoires, un déséquilibre mécanique du système thoraco-pulmonaire ou encore une charge imposée majorée induisant une inadéquation entre la capacité de la pompe musculaire respiratoire et les besoins ventilatoires. A un stade ultime, ces différents facteurs génèrent une hypoventilation menant à l’insuffisance respiratoire de type II.

[more ▼] Purpose. - The aim of this study was to examine Optojump system efficiency to analyse lower limbs explosive strength. Methods and results. - Twenty untrained subjects were randomly assigned to 2 groups: either an experimental group (N = 10) or a control group (N = 10). They performed vertical jumps using different techniques and sprints. Reproducibility of jumps and sprint, evaluated by Optojump system, was appreciated after correlation analysis. The experimental group took part in a plyometric training for six weeks. Jumps and sprints showed an excellent reproducibility (mean coefficiant of variation = 3.6%). Plyometric training increased (P < 0.001) counter movement jump (+ 19.6%), counter movement jump free arms (+14%) and drop jump (+27.9%) performances. Conclusion. - This study demonstrated the accuracy and validity of the Optojump system to analyse lower limbs explosive strength. (c) 2005 Elsevier SAS. Tous droits reserves.
