On percutaneous implants fate and feature
… thesis was to investigate skin reactions around percutaneous abutments in the facial and retroauricular regions. Secondary objectives were to investigate the number of lost extraoral implants and their co-morbidity over time, for example complications because of skin reactions due to the …

The percutaneous absorption of ionisable compounds
… breakdown with respect to pH by HPLC. In vitro percutaneous absorption was observed using the triester, but not the ionic mono- or di-esters. The triester absorption could be potentiated using a range of enhancers with oleic acid being the most effective. Cyclodextrins (CD) have a role as …

Paravalvular sealing pf percutaneous heart valves
Paravalvular regurgitation (PVR), which frequently occurs after transcatheter aortic valve replacements (TAVR) can lead to adverse clinical consequences and has been shown to correlate to an increased late mortality and morbidity. Quantification, graduation and testing for PVR has proven …

Clinical and angiographic outcome following percutaneous coronary intervention
… of linking chapters that follow the evolution of percutaneous intervention from conventional balloon angioplasty in the early to mid 1990s to stent implantation which has now become standard practice. It describes contributions to the extension of clinical situations in which percutaneous …

Robotic and haptic assistance for kidney access during percutaneous nephrolithotomy
Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure for removing kidney stones. Gaining kidney access is the most challenging task in this procedure and the cause of many complications. This thesis presents semi-autonomous solutions for improving PCNL procedure outcomes. First, a …

Percutaneous Puncture of Flexor Sheath Ganglions: An Assessment of Recurrence
… is split between two schools of practice: percutaneous puncture or surgical excision. The literature is equivocal as to which holds true superiority in terms of recurrence rates. The cost of surgical excision is higher and the recovery is longer. In addition, surgery also brings with it the …

Smart Surgical Needle Actuated by Shape Memory Alloys for Percutaneous Procedures
… of cancer interventions today are performed percutaneously using needle-based procedures, i.e. through the skin and soft tissue. Needle insertion is known as one of the recent needle-based techniques that is used in several diagnostic and therapeutic medical procedures such as brachytherapy, …

Development and evaluation summaries of a percutaneous nephrolithotomy (PCNL) surgical simulator
Traditional surgical training methods, such as the use of cadavers, and porcine models (pigs) fall short of providing the realistic, real-time feedback necessary for mastering complex procedures. Virtual reality (VR) simulators with haptics offer a significant improvement, delivering immersive and …

The impact of percutaneous endoscopic gastrostomy feeding on quality of life
… how the provision of enteral nutrition via a Percutaneous Endoscopic Gastrostomy (PEG) impacts on the Quality of Life (QoL) of patients from the patients' and carers' perspectives. Initially, QoL was measured using the SF36 Health questionnaire. A longitudinal, prospective pilot study was …

The use of ion pairs to increase the percutaneous delivery of diclofenac
… amino acid-based ion pairing strategy to enhance percutaneous DF delivery through rational counterion selection and solvent optimisation. The investigation progressed through three phases. First, potential amino acid counterions were identified based on size, toxicity and charge compatibility. …

Chemical and physical methods of enhancing the percutaneous absorption of antimicrobial agents
… of supersaturated solutions in enhancing percutaneous absorption of CHX was investigated. Various anti-nucleating polymers were screened in order to establish the most effective agent. Polyvinylpyrrolidone (PVP, K30) was found to be a better candidate than its lower molecular weight …
