This case report shows a genealogical study where a woman has limb hypertrophy and her son has an association of Sturge-Weber syndrome with Klippel-Trenaunay-Weber syndrome. The Sturge-Weber and Klippel-Trenaunay-Weber syndromes appear to be different manifestations of the same affliction. Familial aggregation exists and transmission may be almost imperceptible between generations. Identificati...

The normalization of energy divergent Weber waves and finite energy Weber-Gauss beams is reported. The well-known Bessel and Mathieu waves are used to derive the integral relations between circular, elliptic, and parabolic waves and to present the Bessel and Mathieu wave decomposition of the Weber waves. The efficiency to approximate a Weber-Gauss beam as a finite superposition of Bessel-Gauss ...

Weber fractions (delta I/I) for gated 500-ms tones at 0.3, 0.5, 1, 2, and 3 kHz, and at levels of the standard ranging from absolute threshold to 97 dB SPL, were measured in quiet and in high-pass noise in five listeners with cochlear hearing loss and in three normal-hearing listeners. In regions of hearing loss, the Weber fractions at a given SPL were sometimes normal. When the Weber fractions...

It has been proposed that idiopathic retroperitoneal fibrosis may be a consequence of 'healed' retroperitoneal lesions of systemic Weber-Christian disease. However ureteric obstruction which is the hallmark of idiopathic retroperitoneal fibrosis, has not been described in systemic Weber-Christian disease. We report a patient with systemic Weber-Christian disease who, during a relapse, developed...

We read with great interest the article written by Alomari et al, and agree with the authors that Klippel-Trenaunay syndrome is not associated with spinal cord AVM. However, in their discussion, in relationship to spinal cord AVM with Parkes Weber syndrome, they comment briefly that “Spinal AVM has not been reported to be a feature of Parkes Weber syndrome.” Here, we demonstrate a case of Parke...

Sets of appropriately normalized eta quotients, that we call level n Weber functions, are defined, and certain identities generalizing Weber function identities are proved for these functions. Schläfli type modular equations are explicitly obtained for Generalized Weber Functions associated with a Fricke group Γ0(n)+, for n = 2, 3, 5, 7, 11, 13 and 17.
