Perineural invasion in mucoepidermoid carcinoma by Emily Anne Lanzel( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

The objective of this study was to retrospectively evaluate the prevalence of perineural invasion in cases of mucoepidermoid carcinoma (MEC). The study will determine if previously assessed perineural invasion by original pathology reports would be increased by re-review of the originally hematoxylin-eosin-(H & E) stained slides as well as review of slides reacted immunohistochemically with S100 to enhance visualization of nerves. The study will also assess whether perineural invasion or its absence in MEC is associated with clinical outcome. Thirty-one cases of major and minor salivary gland MEC were reviewed for perineural invasion and compared to the perineural invasion status stated on the original pathology report when available (13/31). All H & E-stained slides were reviewed as well as S100-reacted sections of each case's tissue blocks that contained tumor. Patient demographics and clinical outcome were collected from electronic medical records. Perineural invasion was identified in 23% (3/13) of tumors in the original reports, 13% (4/31) of the authors' re-review of the same slides, and 29% (9/31) when cases were reacted with S100. A positive relationship was seen between the discovery of perineural invasion on H & E-stained slides and a greater number of foci of perineural invasion. Perineural invasion and larger-diameter nerve involvement was significantly associated with death at 5-year follow-up. In conclusion, immunohistochemical enhancement improves the accuracy, ease and speed of perineural invasion determination. Perineural invasion is a significant factor in the decreased survival outcome of cases of MEC. These findings support continued inclusion of the presence or absence of perineural invasion as a grading parameter in MEC
Comparison of Cranial and Iliac Autologus Bone Grafts and Their Effects on the Success Rates of Subsequent Osseointegrated Intra/Extraoral Implant Application in the Miniature Swine( )

1 edition published in 1992 in English and held by 0 WorldCat member libraries worldwide

Calvarial bone has been reported to be superior to iliac bone for onlay bone grafting due to decreased resorption. This study evaluated the physical, histologic and radiographic characteristics of calvarial and cortico- cancellous iliac onlay bone grafts in nine Pitman-Moore miniature swine at two weeks, one-, two-, four-, six-, eight-, ten- and twelve-month intervals. Compared to iliac grafts, the calvarial onlay grafts had more than a two-fold greater radiographic density. Statistical analysis of the mature grafts using the Standard of Estimated Means of the bone graft volumes revealed 85% retention of the calvarial grafts compared with 34% retention of the grafted iliac bone. There was no subjective difference in the rate or degree of revascularization between the two grafted materials
