Evaluation of erectile dysfunction with the sympathetic skin response in comparison to bulbocavernosus reflex and somatosensory evoked potentials of the pudendal nerve.

Sympathetic skin response (SSR) was investigated in 60 normal subjects (mean age 37.7 +/- 15.9) and 30 patients (mean age 47.

[Sympathetic skin response--physiologic principles, normal values and clinical use].

Sympathetic skin reflex (SSR) was evaluated in the lower extremities of 60 normal volunteers aged 17 to 72 (mean age 38 +/- 16 years, 28 females, 32 males). SSR was obtainable in all volunteers and most often consisted of a biphasic wave with initial negative deflection. Mean latency was 2.

[Progressive supranuclear palsy].

Progressive supranuclear palsy, first described as clinical entity by Steele, Richardson and Olszewski, is a degenerative disorder of the central nervous system. Besides progressive supranuclear oculomotor disturbances, other characteristic signs are pseudobulbar paresis, axial rigidity, gait disturbances and subcortical dementia. Misinterpretation in the early stage as Parkinson's disease is frequently seen.

[Familial spastic spinal paralysis--clinical spectrum and differential diagnostic considerations].

The familial spastic paraplegia is a rare disorder of the cerebral nervous system characterized by a slowly progressive spasticity of the lower limbs with early or late onset. There are pure and complicated forms. The disease is inherited by an autosomal dominant mode and a recessive one.

Polyneuropathy associated with chronic hypoxaemia: prevalence in patients with chronic obstructive pulmonary disease.

The prevalence of clinical and electrophysiological signs of peripheral nerve disease was evaluated in 151 patients with chronic obstructive pulmonary disease. Patients with concomitant disorders affecting the peripheral nervous system were excluded. Thirty patients had clinical signs of a mild sensorimotor and distal neuropathy and 13 additional patients had only electrophysiological abnormalities.
