Introduction Current treatment for erectile dysfunction (ED) mostly attempts to improve erectile function with limited impact on altering the underlying pathophysiology of ED. Recent animal experiments have supported the notion that low intensity extracorporeal shockwave therapy (LIESWT) significantly improves penile hemodynamics and might induce structural changes that regenerate penile tissue. Areas covered This review article provides an overview of the basic mechanics and clinical studies pertaining to LIESWT and its use in the field of ED...

Rana Zakerzadeh, Ming-Chen Hsu, Michael S Sacks
Replacement with a prosthetic device remains a major treatment option for the patients suffering from heart valve disease, with prevalence growing resulting from an ageing population. While the most popular replacement heart valve continues to be the bioprosthetic heart valve (BHV), its durability remains limited. There is thus a continued need to develop a general understanding of the underlying mechanisms limiting BHV durability to facilitate development of a more durable prosthesis. In this regard, computational models can play a pivotal role as they can evaluate our understanding of the underlying mechanisms and be used to optimize designs that may not always be intuitive...

N Mistry, C Coulson, A George
Digital and mobile device technology in healthcare is a growing market. The introduction of the endoscope-i, the world's first endoscopic mobile imaging system, allows the acquisition of high definition images of the ear, nose and throat (ENT). The system combines the e-i Pro camera app with a bespoke engineered endoscope-i adaptor which fits securely onto the iPhone or iPod touch. Endoscopic examination forms a salient aspect of the ENT work-up. The endoscope-i therefore provides a mobile and compact alternative to the existing bulky endoscopic systems currently in use which often restrict the clinician to the clinic setting...

Despite the well-established success of total knee arthroplasty (TKA), iatrogenic ligamentous and soft tissue injuries are infrequent, but potential complications that can have devastating impact on clinical outcomes. These injuries are often related to technical errors and excessive soft tissue manipulation, particularly during bony resections. Recently, robotic-arm assisted TKA was introduced and demonstrated promising results with potential technical advantages over manual surgery in implant positioning and mechanical accuracy...

Orthopedic oncologists often encounter patients with minor bony lesions that are difficult to access surgically and therefore require large exposures out of proportion to the severity of disease that confer significant patient morbidity. Minimally invasive surgical techniques offer the advantage of smaller incisions, shorter operative times, decreased tissue damage, and decreased costs. A variety of surgical procedures have emerged using minimally invasive technologies, particularly in the field of spine surgery...

The presence of severe coronary artery calcification is associated with higher rates of angiographic complications during percutaneous coronary intervention (PCI), as well as higher major adverse cardiac events compared with non-calcified lesions. Incorporating orbital atherectomy (OAS) for effective preparation of severely calcified lesions can help maximize the benefits of PCI by attaining maximal luminal gain (or stent expansion) and improve long-term outcomes (by reducing need for revascularization). Areas covered: In this manuscript, the prevalence, risk factors, and impact of coronary artery calcification on PCI are reviewed...

Extracorporeal life support emerged as a salvage option in patients with therapy-refractory severe hemodynamic or respiratory failure. However, this promising therapy option has been limited by the use of experienced teams in highly specialized tertiary-care centers. Thus, in order to provide this standard of care in local hospitals and due to increasing evidence on improved outcomes using ECMO devices and setting for patients with heart and lung failure, an increasing number of experienced ECMO centers have launched mobile ECMO retrieval services in recent years...

Knowledge of forces, exerted on the brain tissue during the performance of neurosurgical tasks, is critical for quality assurance, case rehearsal, and training purposes. Quantifying the interaction forces has been made possible by developing SmartForceps, a bipolar forceps retrofitted by a set of strain gauges. The forces are estimated using voltages read from strain gauges. We therefore need to quantify the force-voltage relationship to estimate the interaction forces during microsurgery. This problem has been addressed in the literature by following the physical and deterministic properties of the force-sensing strain gauges without obtaining the precision associated with each estimate...

Antonios P Antoniadis, Jonathan M Behar, Ben Sieniewicz, Justin Gould, Steven Niederer, Christopher A Rinaldi
Cardiac Resynchronization therapy (CRT) improves the quality of life and reduces morbidity and mortality of certain patients with heart failure. However, not all patients respond positively after CRT and about one third of cases do not experience benefit. Suboptimal biventricular pacing may account for this and quadripolar left ventricular (LV) leads have emerged in the last years to address issues relating to inadequate delivery of CRT. Areas covered: This review article concisely summarizes the main technical characteristics of the quadripolar LV leads either currently available in the market today or under final stages of development...
