On physical exam, hypertrichosis on the lesion was notable (Figure 1). Rubbing the lesion resulted in erythema and edema of the lesion. She had no systemic disease and her family history was unremarkable.

What is an `ideally imperfect' crystal? Is kinematical theory appropriate?

Most materials are crystalline because atoms and molecules tend to form ordered arrangements, and since the interatomic distances are comparable with the wavelength of X-rays, their interaction creates diffraction patterns. The intensity in these patterns changes with crystal quality. Perfect crystals, e.g. semiconductors, fit well to dynamical theory, whereas crystals that reveal the stereoche...

What is an Optimal Diagnosis?

Within diagnostic reasoning there have been a numb�r of proposed definitions of a diagnosis, and of an opti­ mal or most likely diagnosis. These include most prob­ able posterior hypothesis, most probable interpretation, most probable covering hypothesis, etc. Most of these approaches assume that the most likely diagnosis must be computed, and that a definition of what should be computed can be...
