Ulnar Head Fracture with Volar Dislocation of the Distal Radioulnar Joint: A Case Series and Systematic Review.

Dislocations of the distal radioulnar joint associated with a fracture of the distal ulna articular surface without an associated radial fracture are extremely rare. We present a case of a fracture of the distal ulna with an associated dislocation of the distal radioulnar joint, where the articular head fragment was displaced anterior to the sigmoid notch. We also present the results of a formal systematic review of these injuries which confirmed this is the first such injury described, although there is a very similar fracture pattern described in the literature with dorsal dislocation.

Impingement-related osteolysis in Motec total wrist arthroplasty: an explant analysis and review of the literature.

We present five cases of osteolysis in the Motec total wrist prosthesis, three around the radial implant, one around the metacarpal implant and one around both. Three of these were progressive and required revision, and biomechanical explant analyses of these revised prostheses were performed. Ex vivo testing of the contact points of the Motec implants was also performed at maximum extension.

Modes of failure following locking plate fixation of the distal radius: a thematic analysis of 517 fractures.

Anterior locking plate fixation of the distal radius is a common procedure with reliable results. Failure of fixation is sometimes seen. The aim of the present study was to identify the reasons for failure.

Biofouling control of membrane distillation for seawater desalination: Effect of air-backwash and chemical cleaning on biofouling formation.

This study explored the applicability of chemical cleaning and air-backwash to alleviate biofouling on seawater membrane distillation (SWMD). Membrane performance and wettability properties maintained at optimum duration and frequency of the treatments, as indicated by low permeate conductivity throughout the tests. The cleaning of the membrane using 2% NaOH by immersing the membrane for 30 min after 240 min operation removed the biofouling layer, indicated by low permeate conductivity of 370 µScm after cleaning.

Ocular Chronic Graft-versus-Host Disease and Its Relation to Other Organ Manifestations and Outcomes after Allogeneic Hematopoietic Cell Transplantation.

Ocular chronic graft-versus-host disease (cGVHD) has been shown to significantly reduce quality of life after allogeneic hematopoietic stem cell transplantation (HSCT). To learn more about this bothersome complication, we investigated the relationship between ocular cGVHD and cGVHD in other organs. We also investigated the associations between ocular cGVHD and overall mortality, nonrelapse mortality, and relapse.

Ocular graft-versus-host disease and dry eye disease after paediatric haematopoietic stem cell transplantation - incidence and risk factors.

Ocular graft-versus-host disease (oGVHD) contributes substantially to morbidity after allogeneic haematopoietic stem cell transplantation (HSCT) but is sparsely investigated in children. We assessed incidence and risk factors for oGVHD and dry eye disease (DED) in a nationwide, single-centre study of 484 consecutive children receiving HSCT during the period 1980-2016. Ophthalmological examinations were performed before and annually at least until five years after HSCT.

Cane sugar crystallization using submerged vacuum membrane distillation crystallization (SVMDC).

The performance of Submerged Vacuum Membrane Distillation and Crystallization (SVMDC) for cane sugar concentration and crystallization was investigated in this study. Using hollow fiber membrane, the effect of operation parameters, such as feed concentration, feed temperature, and feed agitation were evaluated against the permeate flux. Following the operation parameters optimization, long-term SVMDC tests were performed using cane sugar model solution and raw sugarcane juice as the feed.

Chronic ocular graft-versus-host disease after allogeneic haematopoietic stem cell transplantation in Denmark - factors associated with risks and rates in adults according to conditioning regimen.

We investigated risks and hazard rates of developing chronic ocular graft-versus-host disease (oGVHD) in a large nationwide, single centre study by using the criteria proposed by "The International Chronic oGVHD Consensus Group". This retrospective study included 1407 consecutive adults who underwent allogeneic haematopoietic stem cell transplantation (HSCT). Patients were examined by an ophthalmologist according to the hospital's guidelines: baseline examination before HSCT, annually up to 5 years after HSCT.

A presentation of culture-positive corneal donors and the effect on clinical outcomes.

Purpose: Donor-to-host transmission of infectious agents is a rare but well-recognised complication of corneal transplantation and may carry a grave visual prognosis. In this case series, we describe the clinical features and risk factors of using culture-positive donor corneas for transplantation.

Methods: Retrospective chart review of a series of patients who underwent either penetrating keratoplasty (PK) or Descemet's stripping automated endothelial keratoplasty (DSAEK) with positive microbiology cultivation during routine assessment of donor corneal tissue obtained at the time of surgery.

Management of patients with ocular manifestations in vesiculobullous disorders affecting the mouth.

Pemphigoid and pemphigus diseases as well as Stevens-Johnson syndrome present as vesiculobullous disorders of the skin and may additionally involve both the oral cavity and the ocular surface. Ocular involvement ranges from mild irritation and dry eye disease to chronic conjunctivitis, symblepharon, eyelid malposition, ocular surface scarring and severe visual loss. In addition to diagnostic assessments, ophthalmologists must treat the dry eye and meibomian gland dysfunction components of these diseases using a stepladder approach, including eyelid hygiene and lubricants.

Irreducible tongue-type calcaneal fracture due to interposition of flexor hallucis longus.

We present a rare case of interposition of the flexor hallucis longus (FHL) tendon blocking percutaneous closed reduction of a displaced tongue-type calcaneal fracture, and necessitating open repositioning of the tendon and internal fixation through a single extensile lateral approach. Although not recognized until during surgery, with a high index of suspicion, preoperative diagnosis of this injury combination should be possible on high resolution CT, thus enabling better planning of the procedure. The presence of a small sustentacular fragment, especially if markedly displaced or rotated, should further alert the physician as to increased likelihood of such tendon entrapment within the fracture.

Incidence and clinical characteristics of fungal keratitis in a Danish population from 2000 to 2013.

Purpose: Fungal keratitis is a severe sight-threatening condition. The aim of this study was to investigate the incidence and clinical characteristics of fungal keratitis patients living in a temperate climate.

Methods: By reviewing medical records from 2000 to July 2013, patients with fungal keratitis were identified.

Ready-made allogeneic ABO-specific serum eye drops: production from regular male blood donors, clinical routine, safety and efficacy.

Purpose: To overcome problems and delays of the preparation of autologous serum eye drops, a production line of ABO-specific allogeneic serum eye drops from male blood donors was set up in a blood bank. Feasibility, clinical routine, safety and efficacy were evaluated in a cohort of patients with severe ocular surface disorders.

Methods: Serum was derived from 450 ml whole-blood donations from regular male blood donors, produced and tested according to good manufacturing practice and legislation regulating blood products in Denmark.

Postoperative increase in grey matter volume in visual cortex after unilateral cataract surgery.

Purpose: The developing visual cortex has a strong potential to undergo plastic changes. Little is known about the potential of the ageing visual cortex to express plasticity. A pertinent question is whether therapeutic interventions can trigger plastic changes in the ageing visual cortex by restoring vision.

Monocular visual deprivation suppresses excitability in adult human visual cortex.

The adult visual cortex maintains a substantial potential for plasticity in response to a change in visual input. For instance, transcranial magnetic stimulation (TMS) studies have shown that binocular deprivation (BD) increases the cortical excitability for inducing phosphenes with TMS. Here, we employed TMS to trace plastic changes in adult visual cortex before, during, and after 48 h of monocular deprivation (MD) of the right dominant eye.

Histopathology of breast carcinoma following neoadjuvant systemic therapy: a common association between letrozole therapy and central scarring.

Aims: Neoadjuvant systemic therapy of large and locally advanced breast cancers may, through shrinkage, enable breast conservation surgery. Letrozole, an aromatase inhibitor, is used frequently in the treatment of oestrogen receptor-positive breast cancer. The aim was to examine the response patterns in a letrozole-treated group compared with a chemotherapy-treated group.

Cold ischemia time in renal transplantation is reduced by a timesheet in a French transplant center.

Background: Cold ischemia time (CIT) is associated with delayed graft function (DGF) and transplant outcome. Several strategies to reduce CIT have been proposed. We retrospectively analyzed the effect of using a timesheet on CIT in our center.

[Reduction of the renal transplantation cold ischaemia time by the use of a timesheet].

Objective: Reduction of the cold ischaemia time is one of the major objectives designed to improve the quality and cost of renal transplantation. Based on the experience of other centres, we report the impact of using a renal transplantation timesheet on the cold ischaemia time in our centre.

Material And Method: Since March 2004, we have used a renal transplantation timesheet with the collaboration of all personnel involved in transplantation (coordination, nephrologists, clinical pathologists).

Numerical simulation of a natural gradient tracer experiment for the natural attenuation study: flow and physical transport.

Results are presented for numerical simulations of ground water flow and physical transport associated with a natural gradient tracer experiment conducted within a heterogeneous alluvial aquifer of the Natural Attenuation Study (NATS) site near Columbus, Mississippi. A principal goal of NATS is to evaluate biogeochemical models that predict the rate and extent of natural biodegradation under field conditions. This paper describes the initial phase in the model evaluation process, i.
