Neoplasms located in the parotid region, temporal bone, infratemporal fossa, and lateral skull base represent a challenge due to their difficult anatomic location and surrounding neurovascular structures. A variety of surgical approaches are appropriate to access this area, although several of them can place the auricular blood supply in danger. If the auricular blood supply is compromised, ischemia and, eventually, avascular necrosis of the auricle can occur. Auricular necrosis often can cause patients a delay in adjuvant radiation therapy and result in the need for additional reconstructive procedures...

Immediate breast reconstruction is an important tool for patients to accept and overcome their breast cancer, as well as for cosmetic reasons. However, its use in patients who require postmastectomy radiation therapy (PMRT) is not yet clear. The purpose of this study was to analyze the effects of PMRT and reconstruction on each other. The time of initiation of PMRT, the prognosis, and the cosmetic results were investigated in patients who underwent immediate reconstruction using autologous tissue. In the case of delayed reconstruction using autologous tissue after PMRT, radiation damage of the chest skin, design of the flap, and cosmetic results were investigated...

INTRODUCTION: Research regarding psychological risk factors for reduced weight loss after bariatric surgery has yielded mixed results, especially for variables measured prior to surgery. More profound personality factors have shown better promise and one such factor that may be relevant in this context is time perspective, i.e., the tendency to focus on present or future consequences. The aim of this study was to investigate the predictive value of time perspective for 12-month weight loss after Roux-en-Y gastric bypass surgery...

Team cognition is an important factor in evaluating and determining team performance. Forming a team with good shared cognition is even more crucial for laparoscopic surgery applications. In this study, we analyzed the eye tracking data of two surgeons during a laparoscopic simulation operation, then performed Cross Recurrence Analysis (CRA) on the recorded data to study the delay behaviour for good performer and poor performer teams. Dual eye tracking data for twenty two dyad teams were recorded during a laparoscopic task and then the teams were divided into good performer and poor performer teams based on the task times...

BACKGROUND/OBJECTIVES: Delayed treatment failure occurs in a significant proportion of inflammatory bowel disease (IBD) patients treated with tumor necrosis factor-alpha (TNF) antagonists. Identification of predictors of loss of response (LOR) may help to optimize therapy. We sought to determine whether body composition parameters at the commencement of anti-TNF therapy were associated with earlier treatment failure. SUBJECTS/METHODS: A retrospective cohort study was performed on 68 patients who had undergone cross-sectional abdominal imaging coincident with the commencement of anti-TNF drugs...

One third of adult patients with orthognathic surgery of a prognathic or retrognathic mandible show relapse. The sagittal split osteotomy of the mandible leads to a displacement of both parts up to 10 mm without any changes of muscle attachment. Changed mandible length needs adaptation of muscle capacity because of changed force to moment ratio. The aim of this Microarray study was to analyze the general genetic response of masseter muscle in patients with retrognathism or prognathism of the mandible six months after surgery in comparison with healthy untreated controls...

The goals of sarcoma management include both a cure and the functional preservation of involved tissues and adjacent critical structures with common opinions favoring immediate reconstruction. The question arises whether these goals are contradictory. This paper discusses the question based on the experience of 28 patients with different types of extremity sarcoma, with 24 surgically treated by the University of California San Diego (UCSD) orthopedic and plastic surgery team (2011-2016) and the collection of evidence from published practice guidelines, reviews, case studies, and clinical trials...

BACKGROUND: The prevalence of obesity and obesity-related morbidity in end-stage renal disease patients is rising. Although it is established that obesity does not abrogate the transplant benefit with respect to lower long-term mortality and cardiovascular risk, it is associated with increased graft failure, delayed graft function, surgical complications, prolonged hospital stay, and costs. OBJECTIVES: To examine the safety and efficacy of LSG (laparoscopic sleeve gastrectomy) in renal transplant candidates and evaluate transplant outcomes...

OBJECTIVE: Spinal arteriovenous fístulas (SAVF), a rare type of vascular malformation, account for 3% of all spinal cord lesions. Without early treatment, the associated morbidity is high; furthermore, SAVF pose a major diagnostic challenge. Our purpose was to evaluate the clinical characteristics of SAVF and review their progress after treatment to determine whether it may be too late for treatment in some cases. METHODS: We present a retrospective series of 10 patients diagnosed with SAVF and treated at a tertiary hospital during a 3-year period...
