In plastic and reconstructive field, it would be much beneficial to fabricate an engineered adipose tissue substitute allowing reliable and complete fat tissue regeneration. Tissue engineering chamber (TEC) holds the promise to optimize an adipogenic configuration that is efficacious as well as reproducible. A frequently occurring complication involves the adipose tissue flap encapsulation and, effectively, its shielding, by a thick fibrous membrane, which hinders development into the proliferative stage. The reason for the deposition of the collagen capsule remains unclear...

The perception of medical specialists by the public has a significant effect on health-care decisions, research funding allocation, and implantation of educational measures. The purpose of this survey was to assess the public's perception of the field of plastic surgery practice. General public members (n = 1290) completed a survey where they matched nine specialties with 28 plastic surgery-related scenarios. Response patterns were distributed as "plastic surgeon alone," "plastic surgeon combined with other specialists," or "no plastic surgeon...

REVIEW
Kai Yang, Alexander Graf, James Sanger
Heterotopic ossification (HO) is widely recognized as a common occurrence among patients suffering from traumatic spinal cord injuries (SCI). The exact etiology of HO formation remains unknown. Published medical and surgical management strategies are often plagued with questionable effectiveness and frequent complications. There are minimal publications regarding the management strategies of HO in SCI patients as it pertains to plastic surgery. We present a case series of patients treated at our institution who underwent treatment for pressure ulcers with underlying HO to highlight the vast spectrum of clinical phenotypes present in this population...

INTRODUCTION: Concealed penis (CP) is a rare problem faced by urologists and plastic surgeons. CP occurs secondary to trauma, obesity, or infection. Surgical treatment is individualized and based on patient and provider variables. We aim to review our recent experience using meshed split-thickness skin grafting (STSG) for CP management. METHODS: A retrospective review was performed on patients who underwent STSG for CP at our institution. Records were reviewed for demographic, operative, and postoperative variables...

PURPOSE: Accurate assessment of coronary stents using non-invasive CT imaging remains challenging despite new stent materials and improvements in CT technology. Virtual monoenergetic (monoE) images reconstructed from dual energy CT acquisitions potentially decrease artifacts caused by coronary stents. A novel spectral detector technology provides monoE and conventional images simultaneously for all conducted scans. The purpose of our study was to systematically investigate the influence of different monoE reconstructions on the visualization of coronary stent lumen in comparison to conventional images...

OBJECTIVE: For assessing inter-rater agreement the concepts of observed agreement and specific agreement have been proposed. The situation of two raters and dichotomous outcomes has been described, whereas often times multiple raters are involved. We aim to extend it for more than two raters and examine how to calculate agreement estimates and 95% confidence intervals (CIs). STUDY DESIGN AND SETTING: As an illustration we used a reliability study that includes the scores of 4 plastic surgeons classifying photographs of breasts of 50 women, after breast reconstruction into 'satisfied' or 'not satisfied'...

INTRODUCTION: Cierny-Mader (C-M) type IV chronic osteomyelitis represents a complex clinical challenge with permeation of extensive bone and soft tissue involvement. Aggressive debridement through viable tissue margin includes en bloc resection improves the odds of eradication of infection, which creates large bone and soft tissue loss in treating this type of osteomyelitis. The potentially large defects increase reconstruction problems with traditional reconstruction technique. The newly staged induced membrane technique presents length-independent, potential as an alternative reconstruction method for segmental bone defects due to type IV chronic osteomyelitis...

Paul M Glat, Thomas Davenport
The reconstructive ladder is a term coined by reconstructive plastic surgeons to describe levels of increasingly complex management of wounds. The first rungs of the ladder is allowing the wound to heal by secondary intention, advancing up the ladder to direct tissue closure, with skin grafting and tissue transfer (flaps) comprising the higher rungs. Skin grafting and tissue transfer (flaps) at the middle and higher rungs of the ladder are often necessary for the treatment of complex burn injuries. Our purpose is to describe how dehydrated human amnion/chorion membrane allografts may be used as an adjunctive treatment...

Since the introduction of silicone implants, several events have led to considerable uncertainty among the patients, public, and users. So far, however, the necessary steps to significantly improving patient safety have not been taken in any of these cases. Requiring stricter approvals for medical devices, improving monitoring by the regulatory authorities and the revision of the Medical Devices Directive are all initial steps in the right direction towards a change in policy, but are insufficient as an early warning system...

: Despite widespread IMRT treatments at modern radiation therapy clinics, precise dosimetric commissioning of an IMRT system remains a challenge. In the most recent report from the Radiological Physics Center (RPC), nearly 20% of institutions failed an end-to-end test with an anthropomorphic head and neck phantom, a test that has rather lenient dose difference and distance-to-agreement criteria of 7% and 4 mm. The RPC report provides strong evidence that IMRT implementation is prone to error and that improved quality assurance tools are required...
