The consequences of massive weight loss through bariatric procedures as well as diet are overall positive. However, the sequelae of massive weight loss present themselves as soft tissue redundancies in the areas of the lower abdomen, upper thigh, upper arm and breast as well as face and neck. This condition presents significant mechanical, physical and social day-to-day limitations for the quality of life of these patients. Surgical techniques are indicated for the reconstruction of the body shape and therapy of the above named problems and the coexistent psychosocial component. These surgical techniques involve dermolipectomies in different body areas and can lead to significant improvement. In view of the worldwide increase of adipositas and the increasing need for bariatric surgery, a parallel increase in demand for such reconstructive post-bariatric interventions can be foreseen. Early and precise information is crucial for the patients before engaging in weight reduction, as is the coverage of the costs of the resulting secondary reconstructive body contouring interventions by the insurance companies.

This dissertation focuses on the use of fantastic elements in the work of a young generation of writers which explore the possibilities of literary development after and beyond postmodernism. By overtly declaring the fictionality of their fantastic stories by means of frame narratives, texts like Jonathan Safran Foer’s Everything is Illuminated (2002), Michael Chabon’s The Amazing Adventures of Kavalier and Clay (2000), Mark Danielewski’s House of Leaves (2000), David Mitchell’s number9dream (2001) and Yann Martel’s Life of Pi (2001) reassess the communicative value of genre boundaries in an attempt to move beyond postmodern relativity and breakdown of communicability. This clear focus on pragmatic concerns marks a shift in the use of the fantastic which calls for a reconsideration of some of the general critical assumptions about the workings of the mode. Though the relation between reality and fiction remains a central issue, the main concern shifts away from such epistemological and ontological considerations, towards questions concerning the pragmatic function of literary fiction in general and different genres in particular. Instead of dwelling on the typically postmodern concerns about the fictionality of reality and the instability of meaning, the works under discussion emphasise the constructive role fiction plays in dealing with reality, the uses to which it can be put and the functions it fulfils in fashioning our being in the world. Drawing on Iser’s theory of the fictive, Irmtraud Huber therefore suggests a reconceptualisation of the fantastic mode, which newly foregrounds its underlying pragmatic structure. She bring this adapted understanding to bear in a close textual analysis of the above mentioned literary texts, with the aim to account for their use of the mode in their commitment to a larger literary endeavour of a new generation that engages with the inheritance of postmodernism and struggles to come into its own.

BACKGROUND -Cardiac tamponade is the most dramatic complication observed during atrial fibrillation (AF) ablation and the leading cause of procedure-related mortality. Female gender is a known risk factor for complications during AF ablation; however, it is unknown whether women have a higher risk of tamponade. METHODS AND RESULTS -A systematic Medline search was used to locate academic electrophysiologic (EP) centers that reported cases of tamponade occurring during AF ablation. Centers were asked to provide information on cases of acute tamponade according to gender and their mode of management including any case of related mortality. Nineteen EP centers provided information on 34,943 ablation procedures involving 25,261 (72%) males. Overall 289 (0.9%) cases of tamponade were reported: 120 (1.24%) in females and 169 (0.67%) in males (odds ratio 1.83, P<0.001). There was a reciprocal association between center volume and the occurrence of tamponade with substantial lower risk in high volume centers. Most cases of tamponade occurred during catheter manipulation or ablation; females tended to develop more tamponades during transseptal catheterization. No gender difference in the mode of management was observed. However, 16% cases of tamponade required surgery with lower rates in high volume centers. Three cases of tamponade (1%) culminated in death. CONCLUSIONS -Tamponade during AF ablation procedures is relatively rare. Women have an almost twofold higher risk for developing this complication. The risk of tamponade among women decreases substantially in high volume centers. Surgical back-up and acute management skills for treating tamponade are important in centers performing AF ablation.

The human face is a vital component of our identity and many people undergo medical aesthetics procedures in order to achieve an ideal or desired look. However, communication between physician and patient is fundamental to understand the patient’s wishes and to achieve the desired results. To date, most plastic surgeons rely on either “free hand” 2D drawings on picture printouts or computerized picture morphing. Alternatively, hardware dependent solutions allow facial shapes to be created and planned in 3D, but they are usually expensive or complex to handle. To offer a simple and hardware independent solution, we propose a web-based application that uses 3 standard 2D pictures to create a 3D representation of the patient’s face on which facial aesthetic procedures such as filling, skin clearing or rejuvenation, and rhinoplasty are planned in 3D. The proposed application couples a set of well-established methods together in a novel manner to optimize 3D reconstructions for clinical use. Face reconstructions performed with the application were evaluated by two plastic surgeons and also compared to ground truth data. Results showed the application can provide accurate 3D face representations to be used in clinics (within an average of 2 mm error) in less than 5 min.

Postmodernism, deconstruction and subversion have been the buzzwords of the last few decades. But not any longer. Ever since the end of the millennium an increasingly perceptible desire to turn towards other concerns can be noted. Only, what comes after postmodernism? Where are we going now? Irmtraud Huber suggests some answers to these questions, focusing on novels by Michael Chabon, Mark Z. Danielewski, Jonathan Safran Foer and David Mitchell and highlighting the ways in which they go beyond postmodernism and turn from deconstruction to reconstruction. Approaching the question from an unusual direction by exploring the novelists' particular use of the fantastic mode, this book offers both further insights into the present aesthetic shift and a new perspective on the literary fantastic.

OBJECTIVE To survey retention procedures used in orthodontic practices in Switzerland. MATERIAL AND METHODS A questionnaire previously developed by Renkema et al. (2009) was sent to 223 Swiss orthodontists. The questionnaire comprised six parts, mainly containing multiple-choice questions. Information as to background education of the individual orthodontist, retention in general, frequency of different types of removable or bonded retainers that were used, retention pro- tocol, and the type and size of the wire used for bonded retainers was assessed. RESULTS The overall response rate was 65 percent. Most orthodontists placed a bonded retainer in the upper and lower arch, except when the upper arch was expanded during treatment or when extractions were performed in the upper arch, in which case they placed a combination of fixed and removable retainers. Opinions varied with regard to how many hours the removable retainers should be worn and the duration of the retention phase. As far as bonded retainers were concerned, 87 percent of the orthodontists preferred life-long retention. Ninety-three percent of the orthodontists considered that the development of a guide- line on retention procedures would be useful. CONCLUSIONS The choice of retention procedures is mostly based on orthodontists personal preference. A further research into the long-term effectiveness of individual retention protocols is needed.

PURPOSE To assess the usefulness of cone beam CT (CBCT) for dacryocystography (DCG) using either direct syringing or passive application of contrast medium. METHODS Ten consecutive patients with epiphora who had CBCT-DCG in a sitting position were retrospectively analyzed. CBCT-DCGs were performed using 2 techniques: direct syringing with contrast medium or using the passive technique, where patients received 3 drops of contrast medium into the conjunctival sac before CBCT-DCG. Clinical and radiologic diagnoses were compared for both groups. RESULTS The 10 patients (men = 3) had a mean age of 63.2 years. Both techniques proved to be simple procedures with good delineation of the bone, soft tissue, and the contrast medium in the lacrimal system. No side effects were noted. CONCLUSIONS CBCT-DCG is a useful alternative to determine the localization of stenosis in patients with chronic epiphora.

INTRODUCTION Acute leg ischaemia (ALI) is a common vascular emergency for which new minimally invasive treatment options were introduced in the 1990s. The aim of this study was to determine recent hospital trends for ALI in England and to assess whether the introduction of the new treatment modalities had affected management. METHODS Routine hospital data covering ALI were provided by Hospital Episode Statistics for the years 2000 to 2011 and mortality data were obtained from the Office for National Statistics. All data were age standardised, reported per 100,000 of the population, and stratified by age band (60-74 years and ≥75 years) and sex. RESULTS Hospital admissions have risen significantly from 60.3 to 94.3 per 100,000 of the population, with an average annual increase of 6.2% since 2003 (p<0.001). The rise was greater in the older age group (from 79.9 to 134.4 vs 49.3 to 73.0) and yet procedures for ALI have shown a significant decrease since 2000 from 14.3 to 12.4 per 100,000 (p=0.013), independent of age and sex. Open embolectomy of the femoral artery remains the most common procedure and the proportion of endovascular interventions showed only a small increase. Only a few deaths were attributed to ALI (range: 95-150 deaths per year). CONCLUSIONS Hospital workload for ALI has increased, particularly since 2003, but this trend does not appear to have translated into increased endovascular or surgical activity.
