BACKGROUND Acellular dermal matrices (ADMs) in plastic surgery have become increasingly popular particularly for breast reconstruction. Despite their advantages, questions exist regarding their association with a possible increased incidence of complications. We describe a collective experience of plastic surgeons' use of ADMs in reconstructive breast surgery using an internet-based survey. M...

The use of acellular dermal matrices (ADM) for dural repair is very scantily described in the literature. We report two cases of dural repair using porcine ADM and a literature review. ADM and especially StratticeTM pliable may be a useful alternative to other dural substitutes. Further evaluation would be favorable.

Singular Value Decomposition (SVD) is of great significance in theory development of mathematics and statistics. In this paper we propose the SVD for 3-dimensional (3-D) matrices and extend it to the general Multidimensional Matrices (MM). We use the basic operations associated with MM introduced by Solo to define some additional aspects of MM. We achieve SVD for 3-D matrix through these MM ope...

Suppose (ftj)ist.jtr is a pxp matrix of real-valued infinitely (respectively /«-times continuously) differentiable functions on an open subset fl of R". Then (fti)isi,isp maps the space of ^-tuples of distributions on fl (respectively distributions of order Smonfi) into itself. In the present paper, the pxp matrices (P/)isi,<sp for which this mapping is onto are characterized in terms of the ze...

Dirac matrices, also known as gamma matrices, are defined only up to a similarity transformation. Usually, some explicit representation of these matrices is assumed in order to deal with them. In this article, we show how it is possible to proceed without any explicit form of these matrices. Various important identities involving Dirac matrices and spinors have been derived without assuming any...

The use of prosthetic mesh for the tension-free repair of incisional hernias has been shown to be more effective than primary suture repair. Unfortunately, prosthetic materials can be a suboptimal choice in a variety of clinical scenarios. In general, prosthetic materials should not be implanted into sites with known contamination or infection because they lack an endogenous vascular network an...

IMPORTANCE Acellular dermal matrices have many current and potential applications, but their long-term safety has not been extensively studied. In particular, limited information exists regarding such materials' resistance to infection. OBJECTIVE To assess the resistance to microbial penetration of common acellular dermal matrix materials used in reconstruction after skin cancer excision, tre...
