Macroglobulinemia Waldenström and motor neuron syndrome

One patient suffering from macroglobulinemia Waldenström developed a neurological disease which may be a previously unrecognized paramalignant phenomenon in this disorder. The clinical symptoms and signs indicate a motor neuron syndrome and autopsy revealed degeneration of ventral and lateral funicles in the spinal cord, loss of ventral motor neurons, degeneration of ventral nerve roots and muscular atrophy. The rather low incidence of macroglobulinemia and motor neuron disease suggest some causal relationship rather than a sporadic occurrence of two disorders in the same patient.

[Surgical treatment of malignant skin epitheliomas. Principles, methods, results]

From personal experience in the treatment of 655 patients with malignant epitheliomas of the skin, treated from 1966 to 1973 at the Department of Plastic and Reconstructive Surgery at the University Hospital, Innsbruck, the basic principles, methods, and results of treatment are reported. An adequate resection and a primary reconstruction is the method of choice. The clinical data and follow-up observations are analyzed and special types of treatment and indications are discussed. With it the 5-year-cure-rate of basal-cell carcinomas was 92%, of squamous-cell carcinomas 83%.

A facial fatigability test: a method for detecting 'latent' facial motor lesions by fatigability

This is a simple test for the early recognition of a clinically 'latent' facial motor lesion, which detects the difference in fatigability between the two sides of the peri-oral musculature. Fatigue is produced by the patient's effort to maintain maximal contraction against lateral traction of the angles of the mouth by two weighted hooks. Fatigue is expressed as the distance between the midline of the philtrum and a mark on each hook. Distance plotted against time gives a 'facial fatigue curve'. In the authors ' experience the test has revealed pathological fatigability in 8 cases, 2 intrameatal and 4 large acoustic neuromas--1 of the four not yet confirmed by surgery--and 2 inflammatory processes in the internal auditory meatus, but failed in 1 of intrameatal acoustic neuroma.

On the lifetime-width relation for a decaying state and the uncertainty principle

A new formulation of the uncertainty relation of position and momentum, and of energy and time, is presented. The connection between the lifetime of excited states and the energy width of these states, which does not follow from the usual uncertainty relation, is shown to be a consequence of the expression here derived.

[A new apparatus for finger occlusion plethysmography. Disucssion of the method and diagnostic possibilities]

Based on the principles of an apparatus for the venous-occlusion plethysmography of the finger, which was developed by Goetz in 1934 and which was adapted for clinical usage by the authors of this article in 1971, a largely improved apparatus, which is also suitable for the usage in hospitals, is now presented. The various clinical methods of examination for the diagnosis of acrale bloodflow disturbances are discussed. Angioneuropathies (as for instance the Raynaud-syndrome) of diseases, which are connected with injuries of vessel-walls and stenosis resp. occlusion (M. Raynaud), can be differentiated with great certainty by means of the temperatures (15 degrees C and 32 degrees C), the quotient and the partial analysis of the volume-pulse form.

A note on disjunctive form tautologies

Cook [1] and Karp [2] have shown that a large class of combinatorial decision problems can be solved in time bounded by a polynomial in the size of the problem iff there is a polynomial time procedure for deciding whether a disjunctive formula with at most three literals per disjunct in the propositional calculus is a tautology.
