Objective: This study seeks an alternative to acellular dermal matrix in 2-staged breast reconstruction while minimizing cost. It was hypothesized that use of a Gore DualMesh would allow for similar intraoperative tissue expander fill volumes, time to second-stage reconstruction, and number of postoperative fills compared with acellular dermal matrix at only a fraction of the expense. Methods: ...

BACKGROUND The use of acellular dermal matrix has facilitated immediate prosthesis-based breast reconstruction. However, few studies directly compare surgical outcomes following acellular dermal matrix-based reconstruction with two of the most commonly available materials, AlloDerm and FlexHD. Those studies that are available often do not adequately control for the surgeon as a variable. The au...

Although the peripheral nerve has the potential to regenerate after injury, degenerative processes may be essential to promote axonal growth into the denervated nerve. One hypothesis is that the nerve contains growth inhibitors that must be neutralized after injury for optimal regeneration. In the present study, we tested whether degradation of chondroitin sulfate proteoglycan, a known inhibito...

BACKGROUND Because of concern about safety and efficacy, no pertussis vaccine has been included in the vaccination program in Sweden since 1979. To provide data that might permit the reintroduction of a pertussis vaccine, we conducted a placebo-controlled trial of two acellular and one whole-cell pertussis vaccines. METHODS After informed consent was obtained, 9829 children born in 1992 were ...

Angiosarcoma of the oral cavity is extremely rare. A 77-year-old woman consulted to our hospital because of polypoid mass of the mandibular gingival. Physical examination showed polypoid reddish mass measuring 1.5 × 1.5 × 1 cm in the mandibular gingival posterior to the front tooth. Enucleation of the tumor was performed. Grossly, the tumor was not encapsulated. Histologically, the tumor consis...

The arterial vasculature in the floor region of the mouth and the submandibular region of the crab-eating monkey was studied by the acrylic plastic injection method. 1. The titled regions were found to be supplied by the hyoid branch and the sublingual artery arising from the lingual artery, and the submandibular glandular branch, the mylohyoid branch and the submental artery from the facial ar...

Currently available replacement heart valves all have limitations. This study aimed to produce and characterize an acellular, biocompatible porcine pulmonary root conduit for reconstruction of the right ventricular outflow tract e.g., during Ross procedure. A process for the decellularization of porcine pulmonary roots was developed incorporating trypsin treatment of the adventitial surface of ...
