[Physical activity among seniors : what benefits on geriatric criteria ?]

The elderly population is growing in our societies. Prevention policies are strongly supported by public authorities and one of them is the promotion of physical activity. We propose to detail, through a literature review, the impact of physical activity on the main geriatric criteria.

[Botulinum A toxin and detrusor sphincter dyssynergia: retrospective study of 47 patients]

INTRODUCTION

To assess the efficacy of injections of botulinum toxin type A (BT-A) in the urethral sphincter for treating detrusor sphincter dyssynergia (DSD).

PATIENTS AND METHODS

Retrospective observational study of patients with confirmed urodynamic DSD (neurological and non-neurological etiologies) treated at our center from 2002 to 2010. All patients received 300 IU of DYSPORT® injected transperineally under electromyographic control. Using a visual analog scale (VAS) for mictional disorders and the measure of the post-void residual (PVR) as criteria of efficacy, results were classified as "non-satisfactory" (decrease in the VAS<2 or decrease in the PVR<20%), "intermediate" (decrease in the VAS≥2 or decrease in the PVR≥20%) or "satisfactory" (decrease in the VAS>3 or decrease in the PVR>40%).

RESULTS

Records of 47 patients (7 women and 40 men) were studied. Mean follow-up was 14.2 months. At the end of follow-up, there were 23.4% (11) of "satisfactory" results, 19.1% (9) of "intermediate" results, 42.6% (20) of "non-satisfactory" results and 14.9% (7) of patients lost for follow-up. The mean decrease in PVR was 60 mL (from an average of 212 to an average of 152 mL). No side effect was observed.

CONCLUSION

In this small series reporting the results of the injection of BT-A in the urethral sphincter for DSD, we observed 42.5% of satisfactory or intermediate results without associated side effects.
