AbstractPropeller perforator flaps (PPFs) have long been proven as valid reconstructive tools for a wide range of soft tissue defects in different body regions. During the last decade, despite their numerous advantages, many authors have thoroughly analyzed outcomes of these flaps, sometimes discouraging their use mainly because of a high failure rate. Accurate patient selection, adequate preoperative planning, and an appropriate dissection technique seem to potentially improve outcomes. Our study provides a review of the relevant literature related to PPF complications and of our experience, describing reasons for failure, measures for preventing them, and approaches for a prompt evaluation and management of complications.

Dissection Technique

In the last years, propeller flaps have become an appealing option for coverage of a large range of defects. Besides having a more reliable vascular pedicle than traditional flap, propeller flaps allow for great freedom in design and for wide mobilization that extend the possibility of reconstructing difficult wounds with local tissues and minimal donor-site morbidity. They also allow one-stage reconstruction of defects that usually require multiple procedures. Harvesting of a propeller flap requires accurate patient selection, preoperative planning, and dissection technique. Complication rate can be kept low, provided that potential problems are prevented, promptly recognized, and adequately treated. This paper reviews current knowledge on propeller flaps. Definition, classification, and indications in the different body regions are discussed based on a review of the literature and on the authors’ experience. Details about surgical technique are provided, together with tips to avoid and manage complications.

Purpose This paper reviews an array of psycholinguistic techniques that auditors can deploy to explore written and oral language for signs of deception. The review is drawn upon to propose some elements of a forward research agenda. Design/methodology/approach Relevant literature across several disciplines is identified through keyword searches of major bibliographic databases. Findings The techniques highlighted have considerable potential for use by auditors to identify audit contexts which merit closer audit investigation. However, the techniques need further contextual empirical investigation in audit contexts. Seven specific propositions are presented for empirical testing. Originality/value This paper assembles literature on deceptive communication from a wide range of disciplines and relates it to the audit context. Auditors’ attention is directed to potential linguistic signals of fraud risk, and opportunities for future research are suggested. The paper is consciousness-raising, has pedagogic purpose and suggests critical elements for a future research agenda.

The Creation

Due to the active development of industries using nuclear technology, the creation of highly effective and cost-effective building materials for protection against hazardous ionizing radiation is of increasing interest. Widespread in the field of radiation-protective building materials are barite-containing concrete. The purpose of this article is to establish the prospects of their use in nuclear facilities, as well as to find ways to improve their technical and operational characteristics. For this an analysis of relevant literature and scientific research in the field of radiation-protective materials and, in particular, barite-containing concrete was carried out. The advantages of barite-containing concrete are high radiation-protective properties, environmental friendliness, high density, as well as economic indicators. The disadvantages are high susceptibility to shrinkage deformation and poor resistance to cyclic temperature effects. The addition of barite to the concrete composition allows to increase the coefficient of linear absorption of -rays of the material; also, with the proper selection of the composition, such material may have strength characteristics equal to or superior to the characteristics of concrete with standard compositions. Barite-containing materials have a wide range of applications and can be used both for the production of heavy concrete in the construction of load-bearing structures and in the creation of radiation-protective coatings for walls and floors.

Tissue Defects

Extensive soft tissue defects present a dif!cult problem to the plastic surgeon as they are usually associated with exposed important structures such as vessels, nerves, tendons, joint cavity or bone. Reconstruction of soft tissue defects have a wide range of therapeutic options. We reconstructed soft tissue defect in many areas using free anterolateral thigh flap (ALTF). From Februari 2009 - 2010, 9 cases of soft tissue defects in the face, neck, leg and foot of various etiologic factors were admitted to the plastic and reconstructive surgery unit, Cipto Mangunkusumo general hospital. Trauma is the commonest cause of soft tissue defects of the lower extremity, followed by tumours. The cruris was the commonest site (4 cases, 44,4%). Flap success rate was 66,67 %. Failure was reported 1 cases in this study due to vein compromise. In our hospital, we are quite familiar with Anterolateral thigh flap (ALTF) even though the case is limited. Anterolateral thigh flap (ALTF) is used for reconstruction of various simple and complex soft tissue defects, for big and small defects with cavity (orbita).

Background. The aim of this study was to evaluate quality of life of free anterolateral thigh flap (ALTFF) for reconstruction of tissue defects of total or near-total glossectomy. Methods. Quality of life was assessed by means of the University of Washington Quality of Life (UW-QOL) and the 14-item Oral Health Impact Profile (OHIP-14), after 12 months postoperatively. Results. 65 of 79 questionnaires were returned (82.27%). In the UW-QOL, the best-scoring domain was “shoulder,” whereas the lowest scores were for “chewing” and “pain.” In the OHIP-14, the lowest-scoring domain was “handicap,” followed by “Social disability” and “Psychological disability.” Conclusion. Free anterolateral thigh perforator flaps for reconstruction of total or near-total glossectomy defects after cancer resection would have significantly influenced the patients’ oral functions and quality of life.

Background Technical advancements and increasing experience in the management of soft tissue defects in lower extremities have led to the evolution of decisional reconstructive algorithms. Both propeller perforator flaps (PPFs) and free flaps (FFs) proved to be useful methods of reconstruction for lower extremities defects, offering alternative reconstructive tools. We present a case series of PPFs and FFs for reconstruction of lower limbs defects, analyzing and comparing treatment and outcomes. Methods Through a retrospective analysis, we report our experience in performing PPFs or FFs for reconstruction of soft tissue defects of the lower extremities, in patients admitted between 2010 and 2015 at the Department of Plastic and Reconstructive Surgery, University of Palermo. In these patients, we evaluated location and causes of defects, types of flaps used, recipient vessels, complications, time to healing, and aesthetic outcome. Results A primary healing rate was obtained in 13 patients for PPF and 16 cases for FF. Revision surgery for partial skin necrosis was required in eight cases (PPF: four and FF: four). Recovery time and hospitalization period were eventually shorter in patients with FFs, due to lower rate of complications and revision surgery. Conclusion In the past years, our indications for reconstruction with PPFs in the lower limb have become more restricted, while we favor reconstruction with FFs. Recommendations are provided to orient surgical treatment in small, medium, and large lower limb defects.
