1. Anatomical and physiological aspects of anorectal dysfunction
Abstract : Objective: To analyse the results of anal-sphincter repair; to examine the feasibility of motor latency measurements of the anal sphincter after magnetic sacral stimulation in healthy subjects, patients with a spinal cord injury and patients with faecal incontinence, using a new recording technique; to study, in the same 3 groups, the effects ofphasic magnetic sacral root stimulation on the anal sphincter and rectum; to describe normal, undisturbed anatomy of the anal canal and perianal structures in both men and nulliparous women using high-resolution phased array magnetic resonance imaging; to study pelvic floor movements in healthy volunteers of both sexes using a new instrument.Methods: Latencies were recorded with an intraanal, bipolar sponge electrode and an intrarectal ground electrode.

2. Effects of nucleus pulposus on nerve root circulation and function. Morphologic and functional studies in an experimental model using porcine spinal nerve roots
Abstract : Sciatica due to lumbar disc herniation has for many decades been viewed as a consequence of mechanical compression exerted on spinal nerve roots by the bulging disc tissues. Recent research has, however, indicated that extruded nucleus pulposus (NP) from the intervertebral disc might cause functional and endoneurial morphological changes in spinal nerve roots, without mechanical compression.

3. Prolonged Modulation of the Micturition Reflex by Electrical Stimulation
Abstract : Intravesical electrical stimulation (IVES) has been used in treatment of patients with urinary bladder dysfunctions for more than four decades. While some investigators have reported excellent results others have observed less convincing effects or outright failures. READ MORE
