Transgender and gender diverse (TGD) individuals most often choose for phalloplasty as a means to create masculine external genitalia. The neophallus created in phalloplasty is usually insufficient for penetrative sexual intercourse due to the lack of erectile structures. Therefore, implantation of an internal erectile prosthesis or use of an external device or epithesis is required. Internal prostheses are the main method for attaining penile rigidity after phalloplasty, but they carry a high risk of complications. Previous research has shown that up to 22% of prostheses for cisgender men were explanted due to various reasons, including infection, erosion, and malfunction within 20 months. The lack of reliable and durable erectile devices leads to a large proportion of patients either choosing phalloplasty but never going for the placement of an erectile prosthesis or completely abandoning the idea of GGAS under the form of phalloplasty. Secondarily, TGD individuals may be concerned about complication rates and likely need for additional surgeries associated with penile implant surgery. Therefore, alternative options for transgender and gender non-conforming patients after phalloplasty are needed. These alternatives may be surgical or non-surgical. External penile epitheses or penile splints were originally designed for cisgender men with erectile dysfunction but have been used experimentally by post-phalloplasty transgender men. While there is no data on the usability and durability of penile epitheses in a TGD population, they may be a viable alternative to an internal penile prosthesis after phalloplasty. Penile lifters or splints, marketed as ElatorTM or ErektorTM, are commercially available and consist of two rigid rings connected by rigid metal rods. The biggest of two rings is placed around the base of the phallus, and the second ring is placed behind the coronal ridge. By connecting the rods to the ring at the base of the penis, tension and rigidity between the two rings is created, allowing the user to penetrate their partner and remove the device after intercourse. The current study aims to extend the knowledge on these external devices by comparing them to the implantation of an internal penile prosthesis in post-phalloplasty transgender patients.
This study is part of the clinical evaluation of SEBBIN silicone gel-filled INTEGRITY implants, included in the technical file of the device. The aim of the study is to gather additional data about the safety and effectiveness of the device.
The finger and fingertip are the most frequently amputated body parts, due to work-related incidents. Yet because of space, weight and cost constraints, prosthetic fingers and fingertips are heavy and bulky with limited active motion and sensation. Most are basic variations on the hook and claw. Lower limb prostheses have become extremely technologically advanced in their design and materials, and upper limbs lag behind in all of these areas. This is due to the complexity of the anatomy and function of the upper limb compared to the lower. There are no commercially available prostheses that offers direct sensory feedback and as such, rely on visual feedback from the wearer. The original PROLIMB study (PROLIMB I) used a Leap Motion Controller (LMC) to investigate the type of grasp adaptation that have been undertaken by patients during the rehabilitation process following amputation and compared this to similar data from healthy volunteers. PROLIMB I also looked at refining the tactile feedback system by investigating the sensation felt on amputation sites in order to feed this information into the haptic feedback system. The vision of the PROLIMB II project is to build on the work completed in PROLIMB I and develop and combine mechanistic models of hand motion and haptic sensing to deliver novel, affordable body-powered prosthetic fingertip digits with enhanced motion and sensation to address current clinical needs and support the quality of life of amputees. With collaboration from the University of Warwick (UoW) and University College London (UCL), Steeper Group and Naked Prosthetics the PROLIMB II study will aim to model, design, fabricate and validate a body-powered prosthetic fingertip digit with integrated sensory feedback. The University Hospital Coventry & Warwickshire (UHCW) will provide the clinical facility with which to assess the comfort, usability and acceptance of this prosthetic in the daily lives of patients with digit amputations. This project will be a proof of concept study with verification of the prosthetic in motion capture (gait) laboratories as well as the use of simple validation data collection over a longer period.

Currently there is an increase in the use of bioprosthesis worldwide (> 70% according to national data of the Spanish Society of Thoracic and Cardiovascular Surgery). There is conflicting evidence regarding the long-term survival of patients aged 50-65 years with mechanical (M) or biological (B) aortic prostheses. General consensus of greater complications associated with the use of long-life anticoagulation in M and of reoperation in B. Similar survival with lower MACCE complications in bioprosthesis could reconsider their choice in patients aged 50-65 years, specially in the current TAVI era. The investigators are going to perform a multicentric retrospective observational study (Registry) about 15 year-outcomes Following Bioprosthetic vs Mechanical Isolated Aortic Valve Replacement for Aortic Stenosis in Patients Aged 50 to 65 Years in 30 Cardiovascular Surgery Centers in Spain
