BACKGROUND: Laparoscopic pancreaticoduodenectomy (LPD), a surgical option for nonpancreatic periampullary adenocarcinoma (NPPA), is a complex procedure that has become increasing popular. However, there is no consensus as to whether this technique should be performed routinely. Our aim was to evaluate the outcomes of LPD compared with open pancreaticoduodenectomy (OPD). MATERIALS AND METHODS: From October 2010 to September 2015, 58 LPDs were performed to treat NPPA and were compared with 58 OPDs, which can theoretically be carried out by laparoscopic approach...

Safe operation and health of structures relies on their ability to effectively dissipate undesired vibrations, which could otherwise significantly reduce the life-time of a structure due to fatigue loads or large deformations. To address this issue, nanoscale fillers, such as carbon nanotubes (CNTs), have been utilized to dissipate mechanical energy in polymer-based nanocomposites through filler-matrix interfacial friction by benefitting from their large interface area with the matrix. In this manuscript, for the first time, we experimentally investigate the effect of CNT alignment with respect to reach other and their orientation with respect to the loading direction on vibrational damping in nanocomposites...

With the development of microvascular technology, perforator flaps have gradually become a good alternative for reconstruction of tissue defects. However, the major limitations of perforator flaps include uncertainty in predicting anatomical location of perforators and high variability in perforator size and course, which require preoperative localization techniques. Recently, as one of the preoperative localization techniques, computed tomography angiography was used to determine the number, size, course, and exact emerging point of perforator flaps...

In Behçet's disease (BD) patients, endovascular repair is a reasonable alternative treatment for aortic aneurysms to avoid postoperative anastomotic pseudoaneurysms. However, there are some complications that may occur after endovascular repair. We herein report the case of a 40-year-old man with active BD developed recurrent aortic pseudoaneurysms at the proximal and distal margins of the stent graft and a femoral puncture site pseudoaneurysm 3 months after endovascular abdominal aortic aneurysm (AAA) repair...

In patients with chronic heart failure (HF), the clinical importance of sarcopenia has been recognized in relation to disease severity, reduced exercise capacity, and adverse clinical outcome. Nevertheless, its impact on acute decompensated heart failure (ADHF) is still poorly understood. Dual-energy X-ray absorptiometry (DXA) is a technique for quantitatively analyzing muscle mass and the degree of sarcopenia. Fat-free mass index (FFMI) is a noninvasive and easily applicable marker of muscle mass.This was a prospective observational cohort study comprising 38 consecutive patients hospitalized for ADHF...

At the beginning of the 19th century, gynaecological cancer, mainly cancer of the uterus and cervix was a dreadful, incurable affection. However, the popularization of the three fundamentals in surgery, anesthesia, asepsis and haemostasis, ushered the golden age of operative gynaecology. During that period distinguished surgeons/gynaecologists such as Friedrich Benjamin Osiander (1759-1822), Elias von Siebold (1775-1828) and Joseph-Claude-Anthelme Récamier (1774-1852) contributed to the development of the operative techniques, providing a therapeutic solution in gynaecological cancer...

PURPOSE: The knife is the most common used instrument for endoscopic urethrotomy. Unfortunately, there are high recurrence rates; it is thought that a laser reduces those rates. We compared the two techniques in this retrospective study. MATERIALS AND METHODS: Between 2010 and 2014, 127 patients were operated on with the knife (KG) and for 65 patients, the laser (LG) was used. We scored the complexity of the stricture using the UREThRAL stricture score (USS) and we scored if a treatment was successful...

PURPOSE OF REVIEW: Rotator cuff injuries are a common cause of pain and dysfunction for the elite athlete and can result in time loss from participation. This review highlights the current management of these injuries. RECENT FINDINGS: Conservative management of rotator cuff injuries continues to be the "gold standard" in the elite athlete. This includes a comprehensive rehabilitation program, anti-inflammatories, and corticosteroid injections. Newer treatment techniques such as intramuscular dry needling and the use of biologics such as platelet-rich plasma and stem cells demonstrate early promising results; however, these modalities require further investigation to determine their effectiveness...

During the past 2 decades, deep brain stimulation (DBS) took over the position of radiofrequency (RF) lesioning of thalamic or pallidal targets for control of movement disorders. Superiority of DBS over RF lesioning is widely accepted, and most neurosurgeons even regard RF lesioning to be old-fashioned and dangerous. Such concepts emerged from the data of old stereotactic operations with ventriculography and without computerized planning. Hardware-related complications are not negligible in long-term DBS therapy, and DBS only controls the symptoms...

BACKGROUND: Hip dislocations are a common presentation in the Emergency Department (ED) and require urgent reduction to reduce the risk of avascular necrosis. Over 90% of all dislocations can successfully be reduced in the ED and there is evidence that cases awaiting operative reduction result in significant delays. DISCUSSION: While there is limited data comparing specific techniques, the individual success rates of most maneuvers range from 60-90%. Additionally, each technique has distinct advantages and limitations associated with its use...

Retinoic acid (RA) is a vital morphogen for early patterning and organogenesis in the developing embryo. RA is a diffusible, lipophilic molecule that signals via nuclear RA receptor heterodimeric units that regulate gene expression by interacting with RA response elements in promoters of a significant number of genes. For precise RA signaling, a robust gradient of the morphogen is required. The developing embryo contains regions that produce RA, and specific intracellular concentrations of RA are created through local degradation mediated by Cyp26 enzymes...
