Focal dermal hypoplasia (Goltz) syndrome is a rare genetic disorder characterized by cutaneous, ectodermal and meso dermal defects. We present a case in which painful, exophytic granulation tissue has been the main symptom over the past 15 years. After unsatisfactory results with a number of treatment modalities.i.cluding topical steroids, silver-nitrate applications, cryotherapy, curettage, excision and pulsed-dye laser, we achieved significant benefit with curettage in combination with photodynamic therapy. Although impaired wound healing has been described in focal dermal hypoplasia, this.i., to our knowledge, the first time that pyogenic granuloma-like lesions have been reported.

This paper describes an analytical model for bulk electron mobility in strained-si layers as a function of strain. Phonon scattering, columbic scattering and surface roughness scattering are included to analyze the full mobility model. Analytical explicit calculations of all of the parameters to accurately es.i.ate the electron mobility have been made. The results predict an increase in the electron mobility with the application of biaxial strain as also predicted from the basic theory of strain physics of metal oxide semiconductor （MOs） devices. The results have also been compared with numerically reported results and show good agreement.
