OBJECTIVES: We recently developed a novel minimally invasive surgical approach that combines extracorporeal membrane oxygenation and CentriMag ventricular assist device (Ec-VAD) for the treatment of cardiogenic shock as a short-term circulatory support. We compared the outcomes of this new approach to conventional CentriMag biventricular assist device (BiVAD) support through a median sternotomy. METHODS: Between July 2015 and August 2016, 22 patients were implanted with CentriMag Ec-VAD and 90 patients were implanted with conventional CentriMag BiVAD...

INTRODUCTION: Authors describe and analyze an implant-prosthetic rehabilitation of posterior partially edentulous jaw by using a super-short implant, according to the platform switching technique, on which a lithium disilicate made crown was cemented. METHODS: One event of partially edentulous jaw in 2.6 region needing implant-prosthetic rehabilitationwas selected for this treatment. Because of the lack of vertical bone, a super-short implant (6mm in diameter and 6mm in length) has been placed according to the platform switching technique by using surgical and prosthetic components lower in diameter compared to the diameter of the implant's platform...

INTRODUCTION: To date, clinically available expanded polytetrafluoro- Ethylene (ePTFE) vascular grafts are suboptimal for reconstructing small Caliber (D<;6mm)arteries, owing to thrombosis in early and restenosis in; late stage. Our aim in this preliminary study was to fabricate a nano-fibrous vascular graft which was biofunctionalized with VEGF and hepa-rin. The short term performance was evaluated both in vitro and in vivo. METHOD: 4 mm caliber grafts were prepared by the coaxial-elctrospun technique, which consisted of poly (l-lactide-co-caprolactone) [P (LLA-CL)] collagen and elastin...

C Zhao, G J R Slater
INTRODUCTION: Extraction of broken femoral nails in peri-implant fractures is becoming an increasingly common problem faced by orthopaedic surgeons. Different closed and open techniques for removal of broken nails have been previously described but due to variations in equipment and fracture configurations these methods are not always easily reproducible. We describe an open surgical technique using simple equipment that can be utilised when other methods of extraction have failed. CASE PRESENTATION AND SURGICAL TECHNIQUE: We present a case of a peri-implant fracture secondary to non-union involving a short cephalomedullary nail where the broken distal segment of nail was significantly more distal to the femoral fracture site...

A long-standing tenet of evolutionary endocrinology states that testosterone mediates the life-history trade-off between mating and paternal care. However, the support for a role of testosterone in suppressing paternal care is mixed: implantation studies in birds suggest that high-level testosterone implants suppress paternal care, but circulating levels of testosterone and paternal care are typically not correlated. Because any trade-off in real life must be realized with hormone levels that are within an individual's reaction norm, it is crucial to show that natural changes in the hormone can modulate behaviour...

Purpose/Aim: High pressures of gases such as nitrogen enhance production of singlet oxygen. Therefore, we hypothesized that growth of non-small cell lung cancer (NSCLC) A549 cells and a human-derived NSCLC explant could be inhibited by an oxidative stress mechanism using high-pressure nitrogen. MATERIALS AND METHODS: Growth of human NSCLC explants and A549 cells in Matrigel were assessed after implantation into nude mice who were exposed to elevated pressures. RESULTS: Subcutaneous implant growth of NSCLC in nude mice was inhibited by a daily 78-minute protocol using nitrogen/oxygen breathing mixture such that at the maximum pressure of 2...

Despite recent interest in amorphous ceramics for a variety of nuclear applications, many details of their structure before and after irradiation/implantation remain unknown. Here we investigated the short-range order of amorphous silicon oxycarbide (SiOC) alloys by using the atomic pair-distribution function (PDF) obtained from electron diffraction. The PDF results show that the structure of SiOC alloys are nearly unchanged after both irradiation up to 30 dpa and He implantation up to 113 at%. TEM characterization shows no sign of crystallization, He bubble or void formation, or segregation in all irradiated samples...

Osteochondral defects (OCDs) of the talus remain a surgical challenge, especially after failed primary treatment. The aim of the present study was to examine the clinical outcomes after HemiCAP(®) implantation for OCDs of the medial talar dome after failed previous surgery. Our retrospective study included 11 patients, who had undergone surgery from June 2009 to September 2012 for an OCD of the medial talar dome and received a HemiCAP(®) on the talus after failed previous surgery for OCD. The data were acquired using patients' medical records and standardized questionnaires, including the Foot and Ankle Outcome Score (FAOS), University of California at Los Angeles (UCLA) activity score, EQ-5D, numerical rating scale (NRS), and Short-Form 36-item Health Survey (SF-36)...

OBJECT: Chronic neuropathic pain is estimated to affect 3-4.5% of the worldwide population, posing a serious burden to society. Deep Brain Stimulation (DBS) is already established for movement disorders and also used to treat some "off-label" conditions. However, DBS for the treatment of chronic, drug refractory, neuropathic pain, has shown variable outcomes with few studies performed in the last decade. Thus, this procedure has consensus approval in parts of Europe but not the USA. This study prospectively evaluated the efficacy at three years of DBS for neuropathic pain...

A 59-year-old male patient was admitted with the main complaints of stuffiness and shortness of breath. An ECG from precordial leads on admission showed masquerading bundle branch block. Syncope frequently occurred after admission. During syncope episodes, ECG telemetry showed that the syncope was caused by intermittent complete atrioventricular block, with the longest RR interval lasting for 4.36 s. At the gap of syncope, ECG showed complete right bundle branch block accompanied by alternation of left anterior fascicular block and left posterior fascicular block...
