Congenital ring constrictions with entrapment neuropathies.
An eight year old boy with multiple simple congenital ring constrictions is described with peripheral nerve palsies caused by entrapment in the constrictions. It is suggested that ring constrictions should be considered in the differential diagnosis of entrapment neuropathy.
متن کاملThe pathology of congenital ring constrictions.
l. They increase in frequency with their nearness to the extremities of the body, being very common in the fingers and toes, less common on the limbs and extremely rare on the body. I have seen one case with a typical one right round the lower thorax, but have not heard of another. 2. It is common to find two or more digits fused together at their tips, with a ring constriction round the fused ...
متن کاملPharyngeal constrictions.
From a fiberscope, the tip of which was swung from left to right in the pharynx, cinefilm frames were obtained which showed the cross-sectional shape of pharyngeal constrictions in back vowels. This information was combined with the information offered by X-ray pictures of the same subject phonating the same vowels on a different occasion. The results agree to a reasonable extent with previousl...
متن کاملConductance through analytic constrictions
We study the dependence of the intrinsic conductance of a nanocontact on its shape by using the recursion-transfer-matrix method. Hour-glass, torus, and spherical shapes are defined through analytic potentials, the latter two serving as rough models for ring-like and spherical molecules, respectively. The sensitivity of the conductance to geometric details is analyzed and discussed. Strong reso...
