The blanket principle: a technical note.

Low-frequency attenuation of motor unit potentials may reveal abnormal complexity and instability of the motor unit. An ordinary concentric needle electrode is used, so the method bridges the gap between single-fiber and conventional electromyography.

Renocolic fistulas: complementary roles of computed tomography and direct pyelography.

Three patients with renocolic fistulas are presented. Antegrade or retrograde pyelography showed the fistula in one patient but was unsuccessful in two others. CT demonstrated perinephric inflammation extending to the colon, complex air-fluid collections within the kidney, or extension of renal contrast into the colon. CT and direct pyelography complement each other for the diagnosis of renocolic fistulas.

[Retinal nerve fibers and automated visual fields during the course of primary open-angle glaucoma].

Retinal nerve fiber examination is confronted with the results of automatic exploration of visual field with Octopus. 99 eyes affected by open angle glaucoma were studied during a period of 4 years or less. Analysis is done in accordance with the course under therapy. Good pressure results are obtained. Meanwhile visual field indexes show a slow deterioration under medical treatment, a stabilisation after laser trabeculoplasty and a marked improvement after surgery (trabeculectomy). Retinal nerve fiber are clear prior affected in comparison with visual field in early glaucoma, and a perfect agreement is demonstrated in mature cases.
