INTRODUCTION: Current guidelines in the United States require reporting only the 30-day postoperative outcomes to standardized databases, including the National Surgical Quality Improvement Program (NSQIP). Thus, many breast implant-related complications go unreported in standard databases. We sought to characterize late periprosthetic infections following implant-based breast reconstruction. METHODS: We conducted a retrospective analysis of all women who underwent expander/implant reconstruction from 2005 to 2014 at two institutions...

The traditional rhytidectomy addresses facial and neck aging as it relates to soft tissue laxity. The modern volumetric facelift provides optimal results by addressing not only skin laxity but also the loss of volume secondary to tissue atrophy and bony resorption. While multiple techniques including fat grafting, dermal fillers, and tissue resuspension are used to correct the tissue loss, alloplastic midface augmentation remains the most permanent method. In our practice we often address midface cheek hollowness or atrophy with the placement of submalar implants at the time of rhytidectomy...

In this study, selective laser melted patient specific functional implants (PSFI) were utilised in combination with a fibula free flap, for mandible reconstruction. The shape and length of the PSFI, the shaping of fibula graft, its angulation and the length of the screws, were virtually planned before the surgery. Information, such as resection margin and screw lengths, were coded on the implant. 22 patients were reconstructed with PSFI and fibula transplantation. Data collected related to the size of the defect, pre- and postoperative intercondylar distance, ischemia time, time consumed to shape the fibula graft and complications...

Hepatocellular carcinoma (HCC) metastasis is often associated with the activation of Wnt/β-catenin signaling pathway. Zanthoxylum avicennae (Ying Bu Bo, YBB), a traditional herb with hepatoprotective effect, has been proven to inhibit human HCC in in vivo models however, the in vitro and in vivo effect of YBB on tumor metastasis is not clear yet. To determine whether YBB could inhibit HA22T human HCC cell by acting on β-catenin metastatic signaling in vitro and in vivo, HA22T cells were treated with different concentrations of YBB extracts (YBBE) and analyzed by Immunofluorescence staining assay, western blot analysis, siRNA mediated gene knock-down assays and co-immunoprecipitation assay...

BACKGROUND: Many recipients of bilateral cochlear implants (CIs) may have differences in electrode insertion depth. Previous reports indicate that when a bilateral mismatch is imposed, performance on tests of speech understanding or sound localization becomes worse. If recipients of bilateral CIs cannot adjust to a difference in insertion depth, adjustments to the frequency table may be necessary to maximize bilateral performance. PURPOSE: The purpose of this study was to examine the feasibility of using real-time manipulations of the frequency table to offset any decrements in performance resulting from a bilateral mismatch...

Bone consists of a hard mineral phase and a compliant biopolymer phase resulting in a composite material that is both lightweight and strong. Osteoporosis that degrades spongy bone preferentially over time leads to bone brittleness in the elderly. A porous ceramic material that can mimic spongy bone for a one-time implant provides a potential solution for the future needs of an aging population. Scaffolds made by magnetic freeze casting resemble the aligned porosity of spongy bone. A magnetic field applied throughout freezing induces particle chaining and alignment of lamellae structures between growing ice crystals...

PURPOSE: Patient-specific instrumentation (PSI) has the potential to offer numerous benefits-not least of all, improved resection accuracy; but its potential has not been realised in clinical studies. An explanation may be the focus of such studies on the total knee replacement (TKR-a common procedure, with which surgeons are generally very familiar. Consequently, we sought to investigate the potential role of PSI in guiding novice surgeons to perform the more technically demanding and less familiar lateral unicondylar knee replacement (LUKR)...

The occurrence of multifocal intraocular lens (MIOL) is known as an important period in the development of cataract surgery, which can provide a simultaneous vision without the use of spectacles or contact lenses. However, in the current stage, MIOL implantation may also lead to decreased visual acuity and increased risk of photic phenomena, thus in some instance a second procedure to exchange the MIOL is necessary. Optimizing visual outcomes of MIOL implantation and controlling adverse effects has become the focus for ophthalmologists...

Well-coordinated interdisciplinary dental treatments provide the best esthetic, functional, and long-term results for patients. However, the length of such treatment, which may involve orthodontics, ridge augmentation, and dental implants, often deters patients from pursuing them. The two case reports presented here aim to present the advantage of simultaneous orthodontic molar uprighting and ridge augmentation procedures for future implant site development. Selective decortication of the alveolar bone, performed simultaneously with bone grafting, can accelerate the tooth uprighting process and synergistically reduce treatment duration...
