A new motion--depth illusion is reported. When a curved aperture translates vertically and stationary horizontal lines can be seen through it, the line lengths on the retina change continuously because of the occlusion. Instead of seeing the aperture translate, subjects sometimes see the lines rotate in depth around a vertical axis. This is a rare kind of illusion: an ambiguous motion which can be seen as either stationary in two dimensions or rotating in three dimensions. Three-dimensional rotation was more often observed when the luminance difference between the horizontal lines and the background was larger than that between the aperture and the background. This illusion demonstrates that motion detection and the structure-from-motion process correlate with figure--ground segregation, depth stratification, and figural-completion processes based on luminance contrast.

This report described a case of scrofuloderma that developed in the bilateral inguinal regions during treatment of bullous pemphigoid with systemic corticosteroid. Analysis of the literature on scrofuloderma between 1978-1993 disclosed that the number of cases with extracervical involvement are increasing. Immunosuppression could disseminate tuberculous focuses, resulting in extracervical involvement of SD connected with the underlying extrapulmonary tuberculous lesions.

A case of a variant of Waardenburg syndrome is reported. A 13-year-old boy with features of Waardenburg syndrome consisting of facial anomalies, heterochromia of the iris and fundus, and congenital sensorineural deafness had a marked mental and motor retardation and developed severe gait disturbance associated with neurological abnormalities including dystonia, muscular stiffness and peripheral neuropathy. Sural nerve biopsy revealed 'onion bulb' formation.
