Contrôle biologique de l’entraînement sportif par spectrométrie IR-TF

The aim of our study is to develop and validate a biological technique of analysis by Fourier transform infrared (FT-IR) spectrometry which uses a microcapillary taken away to measure 19 serum biological parameters.     

Effets psychologiques d’une administration de courte durée de prednisolone

Introduction

The aim of the study is to assess the psychological effects of a short-term therapeutical prednisolone intake.

Synthesis

We studied, according to a double-blind, randomized cross-over protocol, the effects of a seven day prednisolone intake (60 mg/day) in 10 healthy male subjects on global health and mood state. No significant change was found between the treatments (prednisolone/placebo) in the 15 variables investigated. However, tendencies appeared revealing an increase of self-esteem, personal accomplishment and athletic identification, as well as a decrease in negative affect for the subjects under treatment.

Conclusion

These results could reveal a psychological impact of glucocorticoid intake and should be confirmed by a further study with athletes submitted to a more intense physical activity.     

La technique de Didier Patte dans les luxations récidivantes de l’épaule : notre expérience à propos de 35 cas avec un suivi d’une dizaine d’années

Aims

Authors report their personal experience on the surgical treatment of repeated anterior shoulder dislocations, using an anterior bone block in accordance with the procedure suggested by Didier Patte.

Results

From the year 1988 and during 10 years, 35 patients suffering from repeated anterior shoulder dislocations were surgically treated by this procedure. It was appropriate to retrospectively review the clinical and functional outcomes after Patte repair for recurrent anterior glenohumeral instability. The mean follow-up was approximately 10 years, with a mean percentage of 75% for the observance. There was no recurrence after surgery. Moreover, 88% of patients had good outcomes, according to the scale suggested by Butel et al., with total resumption of work and physical activities. The occurrence of chronic complication such as osteoathrosis was scarce (only one case for the series), while 20% of subjects showed apprehension during some specific shoulder movements.

Conclusion

In order to expect best functional outcomes, the choice of the surgical procedure should take into account the extent of initial injury. Considering these ground requirements, the Patte procedure seems to provide very satisfactory long-term functional outcomes.     

Correction de l’hypoxémie d’exercice chez le BPCO : variabilité des réponses, enjeux et problèmes posés dans le cadre de la réhabilitation respiratoire

Aim

To define in chronic obstructive pulmonary disease patients (COPD) moderately hypoxemic in resting conditions, if controlled acute oxygen supplementation was always able to increase exercise tolerance when partial oxygen saturation SpO₂ was corrected.

Results

In hyperoxia, endurance time (T_LIM) was significantly and consistently increased in 14 COPD (+68%) and decreased in seven others (–36%). These two subgroups exhibited no difference in resting values or in their disease severity. COPD with a decreased T_LIM under hyperoxic conditions had an abnormal response to O₂: unchanged cardiac output and ventilation, increased breathing frequency.

Conclusion

This work shows that acute O₂ supplementation responses in COPD are not univocal, either on exercise tolerance or cardio-respiratory variables typically affected by hyperoxia.
