Complex modeling: a strategy and software program for combining multiple information sources to solve ill posed structure and nanostructure inverse problems.

A strategy is described for regularizing ill posed structure and nanostructure scattering inverse problems (i.e. structure solution) from complex material structures.

Paraumbilical perforator flap for soft tissue reconstruction of the forearm.

Numerous flaps exist for coverage of injuries to the upper extremity, ranging from local, to regional, to free tissue transfer. The choice of flap is dependent on a variety of factors, including patient, functional needs, and depth of injury. The paraumbilical perforator (PUP) flap for upper extremity coverage can offer the benefits and versatility of pedicled and free flaps while avoiding some of the donor-site morbidity and risks of free tissue transfer.

Corrugation in exfoliated graphene: an electron microscopy and diffraction study.

Low-energy electron microscopy and microprobe diffraction are used to image and characterize corrugation in SiO(2)-supported and suspended exfoliated graphene at nanometer length scales. Diffraction line-shape analysis reveals quantitative differences in surface roughness on length scales below 20 nm which depend on film thickness and interaction with the substrate. Corrugation decreases with increasing film thickness, reflecting the increased stiffness of multilayer films.

Surgical wound bed preparation of chronic and acute wounds.

Our aging population has presented us with many new challenges. One such challenge is the need to manage an increase in wound-related problems effectively and efficiently. Over time, two parallel, yet divergent, management systems have developed.

The incidence of late cephalohematoma following craniofacial surgery.

Background: Cranial vault remodeling procedures are carried out for both syndromic and nonsyndromic craniosynostosis as well as to correct some acquired deformities of the cranial vault. These procedures improve not only cosmesis but also neurological symptoms. The purpose of this study was to determine the incidence of "late" cephalohematoma, an underreported complication following these complex procedures.

Comparison of wound irrigation and tangential hydrodissection in bacterial clearance of contaminated wounds: results of a randomized, controlled clinical study.

Thorough irrigation of contaminated or infected traumatic and open surgical wounds is considered standard practice. High-power pulse lavage is frequently used to facilitate the removal of surface contaminants and bacteria but studies to compare the results of various irrigation techniques are limited. The purpose of this randomized, controlled clinical study was to compare the ability of a high-pressure parallel waterjet (pressure range 5,025 to 7,360 psi) to pulse lavage (pressure 40 psi) in reducing wound bacterial counts.

Solutions to challenging digital replantations.

Replantation of amputated digits remains one of the most challenging areas in plastic and reconstructive surgery. Complicated cases of digital amputation, such as fingertip amputations, multidigital amputations, and so forth, pose an even greater challenge, requiring extraordinary solutions for successful replantation. The authors present their experience with complicated digital replantations at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School.

Stem cells and distraction osteogenesis: endothelial progenitor cells home to the ischemic generate in activation and consolidation.

Background: Ischemia is a limiting factor during distraction osteogenesis. The authors sought to determine the extent of ischemia in the distraction zone and whether endothelial progenitor cells home to the distraction zone and participate in local vasculogenesis.

Methods: Laser Doppler imaging was used to assess the extent of blood flow in the distraction zone in gradually distracted, immediately distracted, and osteotomized rat mandibles during activation and consolidation.

Infection with nontuberculous mycobacterium after injection of adulterated silicone fluid.

A 57-year-old woman presented with a predominantly right-sided cellulitic area of her buttock after receiving multiple bilateral silicone injections in the buttocks. The workup revealed subcutaneous infection with rapidly growing mycobacteria. Surgical management and etiologic factors are discussed, and a review of the literature is presented.
