Clinical guidelines for cardiovascular disease prevention: Should they differ by gender?

The effects of cardiovascular disease are substantial in women, yet cardiovascular preventive therapies for women are underused. The prevalence and impact of many coronary risk factors differ by gender. Coronary risk interventions (eg, using aspirin) have diverse outcomes in women and men. Results from studies of preventive interventions specific to women (eg, menopausal hormone therapy) have changed preventive recommendations and clinical practice.     

Postprostatectomy incontinence: Pathophysiology and management

Postprostatectomy incontinence in men is a devastating condition impacting the quality of life profoundly. Various types of male sling procedures have been introduced over the years. The bone-anchored male sling appears to be effective and safe in intermediate-term follow-up. It is certainly more effective than collagen implant and may provide an alternative treatment option in patients with mild to moderate incontinence. In the short term, other novel procedures seem promising. In spite of new technology, the artificial urinary sphincter continues to provide high patient satisfaction and cure rates.     

Combining spin echoes with gradient echoes in the context of the global coherent free precession pulse sequence.

To extend the signal longevity of magnetically excited spins in flowing fluids while in a state of global coherent free precession (GCFP), a refocusing radiofrequency (RF) pulse and bipolar gradient waveforms were combined with the GCFP sequence. The data demonstrate that RF refocusing in the presence of flowing blood is possible, but the improvement in signal amplitude depends on the static magnetic field homogeneity along the direction of motion and the displacement of the spins between the excitation and the RF refocusing pulse, as well as displacement during subsequent RF refocusing pulses. The least amount of phase dispersion and thus the longest lasting signal is obtained with the shortest echo spacing where only one line of data is recorded between two RF refocusing pulses. This approach was successfully used in a phantom and in vivo to image fast and slow blood flow. Depending on the experimental conditions, signal persistence is improved significantly compared to playing the same sequence without RF refocusing, but the improvement is limited by the product of blood flow velocity and the time between RF refocusing pulses.     

A nationwide survey of excessive daytime sleepiness in Parkinson's disease in France

To determine the prevalence of excessive daytime sleepiness (EDS) and that of dozing and sudden onset of sleep episodes (SOS) while driving in ambulatory patients with Parkinson's disease (PD) in France, a national sample of private and public neurologists was asked to recruit the first 10 consecutive nondemented PD patients. Each patient completed a questionnaire including the Epworth Sleepiness Scale (ESS) and the likelihood of dozing off and experiencing SOS episodes behind the wheel. Clinical and demographic data were collected. One thousand six hundred and twenty‐five patients with PD were included in the survey. Twenty‐nine percent of the patients suffered from EDS (ESS score ≥10) but only 0.8% declared a high chance of dozing while driving and 0.5% reported totally unpredictable SOS episodes while driving. Risk factors for EDS were male gender, reduced activity of daily living, and a high daily levodopa equivalent dosage. Risk factors for SOS episodes while driving were an ESS score ≥10, male gender, and low Hoehn and Yahr staging. EDS is common in ambulatory patients with PD and is a major risk factor for dozing and for SOS episodes behind the wheel in patients who drive. © 2007 Movement Disorder Society
