    Voiding and MRI Analysis of the Brain (1999)

    Notes: Abstract: Observations of surgery, angiography and postmortem studies have indicated that the frontal lobe is a higher center important in the control of micturition. CT and MRI have made it possible to extend these early observations, and we report here the results of imaging in patients with hemispheric and brain-stem strokes. In a series of stroke patients urinary dysfunction was found in 68% with frontal lesions 20% with parietal, 14% with temporal and none with occipital lobe lesions. With lesions in the frontal lobe, it appears that medial aspects are particularly important in the prefrontal lobe, cingulate gyrus, paracentral lobule and the orbital area in micturition control. Frontal lobe disease may cause disorders of storage as well as voiding, as shown by urodynamics: detrusor hyperreflexia, detrusor areflexia, uninhibited sphincter relaxation and unrelaxing sphincter on voiding were found. We have also had the opportunity to make observations about the role of the basal ganglia and pons in micturition control in humans.

    Urodynamic and cardiovascular measurements in patients with micturition syncope (1997)
    Springer
    Clinical autonomic research 7 (1997), S. 219-221 
    Details
    ISSN: 1619-1560
    Keywords: micturition syncope ; urodynamic study ; vasovagal syncope

    Notes: Abstract We describe the findings of urodynamic studies, together with blood pressure and heart rate monitoring, in five patients with micturition syncope. All patients had almost normal storage and evacuation function and no evidence of prostate hypertrophy. Conventional head-up tilt testing with an empty urinary bladder caused no change in arterial blood pressure, but a moderate increase in heart rate. Urinary bladder filling caused minimal increases of the arterial pressure and heart rate. The sitting posture with a distended bladder caused mild orthostatic hypotension. Urinary bladder evacuation caused a fall in arterial pressure with a decrease in heart rate. These responses were similar to those described in vasovagal syncope. The central mechanism for the initiation of urinary evacuation, or sensory input from the lower urinary tract, may trigger micturition syncope.

    Orthostatic hypotension in a case with multiple sclerosis (1997)
    Springer
    Clinical autonomic research 7 (1997), S. 163-165

    Notes: Abstract A 37-year-old woman with a 5-year history of multiple sclerosis is reported. She began having recurrent syncope even in the sitting position; other neurological features included hiccup, faciooro-lingual flushing and clumsiness of the hands. She had alternating Horner's syndrome, mild hypoalgesia of the right face, exaggerated deep tendon reflexes of the upper extremities, decreased deep sensation and ataxia of the upper extremities, and incomplete transverse myelopathy with a T4 sensory level. Head-up tilt testing confirmed orthostatic hypotension with relative preservation of the heart rate increase. Magnetic resonance imaging indicated abnormal intensities in the paramedian tegmentum and base of the medulla, which may have been additionally responsible for orthostatic hypotension. Steroid pulse therapy andl-threo-3,4-dihydroxyphenylserine caused regression of brainstem signs and reduced syncopal attacks.
