Outcomes of primary total hip arthroplasty in patients with Ehlers Danlos Syndromes.

Background: The Ehlers Danlos Syndromes (EDS) are inherited in an autosomal dominant pattern and patients classically present with hypermobility, skin hyper-elasticity, blood vessel fragility and atrophic scarring. Due to hypermobility, disorders such as joint pain and early arthritis are common. The aim of this study was to assess clinical and radiological outcomes of total hip arthroplasty (THA) in patients with EDS treated in a high volume orthopaedic centre.

2nd and 3rd generation full endoscopic lumbar spine surgery: clinical safety and learning curve.

Aim: 2nd and 3rd generation endoscopic spine surgery techniques offer visualisation of familiar inter-laminar anatomy to spinal surgeons. We have prospectively evaluated the clinical outcome, complications and learning curve associated with these techniques in patients with lumbar spine radiculopathy.

Methods: This is a prospective study of 50 consecutive patients with radicular pain from disc herniation and/or lateral recess stenosis.

The survivorship of revision total hip replacement with severe proximal bone deficiency using a modular taper fluted prosthesis.

Contemporary uncemented femoral revision hip systems have become commonly used over the past decade and have enabled the reconstruction of leg length, offset and anteversion as independent variables through the use of modular junctions. Modular junction failures between the proximal body and distal stem have been described with revision systems, although this is rare. We sought to identify the survivorship of one revision system in a salvage arthroplasty scenario where no host bone support of the modular junction was present.

Effect of COVID-19 on a rural orthopaedic hip fracture service.

Aims: Our rural orthopaedic service has undergone service restructure during the COVID-19 pandemic in order to sustain hip fracture care. All adult trauma care has been centralised to the Royal Shrewsbury Hospital for assessment and medical input, before transferring those requiring operative intervention to the Robert Jones and Agnes Hunt Orthopaedic Hospital. We aim to review the impact of COVID-19 on hip fracture workload and service changes upon management of hip fractures.

Bismuth oxyhalides: synthesis, structure and photoelectrochemical activity.

We report the synthesis and photoelectrochemical assessment of phase pure tetragonal matlockite structured BiOX (where X = Cl, Br, I) films. The materials were deposited using aerosol-assisted chemical vapour deposition. The measured optical bandgaps of the oxyhalides, supported by density functional theory calculations, showed a red shift with the increasing size of halide following the binding energy of the anion p-orbitals that form the valence band.

Tungsten Doped TiO2 with Enhanced Photocatalytic and Optoelectrical Properties via Aerosol Assisted Chemical Vapor Deposition.

Tungsten doped titanium dioxide films with both transparent conducting oxide (TCO) and photocatalytic properties were produced via aerosol-assisted chemical vapor deposition of titanium ethoxide and dopant concentrations of tungsten ethoxide at 500 °C from a toluene solution. The films were anatase TiO2, with good n-type electrical conductivities as determined via Hall effect measurements. The film doped with 2.

Superhydrophobic silica wool-a facile route to separating oil and hydrophobic solvents from water.

Silica microfiber wool was systematically functionalized in order to provide an extremely water repellent and oleophilic material. This was carried out using a two-step functionalization that was shown to be a highly effective method for generating an intense water repulsion and attraction for oil. A demonstration of the silica wools application is shown through the highly efficient separation of oils and hydrophobic solvents from water.

PbO-modified TiO2 thin films: a route to visible light photocatalysts.

PbO clusters were deposited onto polycrystalline titanium dioxide (anatase) films on glass substrates by aerosol-assisted chemical vapor deposition (AACVD). The as-deposited PbO/TiO2 films were then tested for visible light photocatalysis. This was monitored by the photodegradation of stearic acid under visible light conditions.

Atmospheric pressure chemical vapour deposition of boron doped titanium dioxide for photocatalytic water reduction and oxidation.

Boron-doped titanium dioxide (B-TiO2) films were deposited by atmospheric pressure chemical vapour deposition of titanium(iv) chloride, ethyl acetate and tri-isopropyl borate on steel and fluorine-doped-tin oxide substrates at 500, 550 and 600 °C, respectively. The films were characterised using powder X-ray diffraction (PXRD), which showed anatase phase TiO2 at lower deposition temperatures (500 and 550 °C) and rutile at higher deposition temperatures (600 °C). X-ray photoelectron spectroscopy (XPS) showed a dopant level of 0.

Textured fluorine-doped tin dioxide films formed by chemical vapour deposition.

The use of an aerosol delivery system enabled fluorine-doped tin dioxide films to be formed from monobutyltin trichloride methanolic solutions at 350-550 °C with enhanced functional properties compared with commercial standards. It was noted that small aerosol droplets (0.3 μm) gave films with better figures of merit than larger aerosol droplets (45 μm) or use of a similar precursor set using atmospheric pressure chemical vapour deposition (CVD) conditions.

Implantable pulse generators (pacemakers) and electrodes: safety in the magnetic resonance imaging scanner environment.

Static magnetic fields, time-varying electric and magnetic fields, and electromagnetic interference within the magnetic resonance imaging scanner environment can cause the implantable pulse generator (pacemaker) to malfunction and render the electrodes hazardous to the patient. This article provides a review of the literature and of international regulatory guidance concerning safety considerations when these implantable devices are exposed to magnetic resonance imaging.
