Traumatic lateral dislocations of the first metatarsophalangeal (MTP) joint are very rare. A 44-year-old male was referred after a motorcycle to car accident because of an exposed head of the left first metatarsal through a laceration on the medial aspect of the first MTP joint. Radiographs showed a lateral dislocation of the first MTP joint, with concomitant fractures of the neck of the second metatarsal and the base of the third and fourth metatarsal bones. The dislocation was reduced in the emergency department with the patient under conscious sedation after thorough irrigation...

REVIEW
P Bonnevialle
Early infection after open reduction and internal fixation (ORIF) of a limb bone is defined as bacteriologically documented, deep and/or superficial surgical-site infection (SSI) diagnosed within 6months after the surgical procedure. This interval is arbitrarily considered sufficient to obtain fracture healing. The treatment of early infection after ORIF should be decided by a multidisciplinary team. The principles are the same as for revision arthroplasty. Superficial SSIs should be differentiated from deep SSIs, based on the results of bacteriological specimens collected using flawless technique...

Hoffa fracture is a rare type of fracture confined to the coronal plane of the femoral condyle. High-energy is a common reason of Hoffa fracture, and low-energy trauma and iatrogenic injury can also cause Hoffa fracture in some cases. The commonly used classifications include Letenneur classification, CT classification, AO classification and modified AO classification. X-ray is the first choice to diagnose Hoffa fractures, fracture lines can be found. If the X-ray is negative, CT scan and MRI should be performed...

In this paper, the hydraulic and heat-transfer properties of two sets of artificially fractured granite samples are investigated. First, the morphological information is determined using 3D modelling technology. The area ratio is used to describe the roughness of the fracture surface. Second, the hydraulic properties of fractured granite are tested by exposing samples to different confining pressures and temperatures. The results show that the hydraulic properties of the fractures are affected mainly by the area ratio, with a larger area ratio producing a larger fracture aperture and higher hydraulic conductivity...

INTRODUCTION: Over recent years there has been growing evidence of increased risk of mortality associated with antipsychotic use in older people with dementia. Although this concern combined with limited evidence of efficacy has informed guidelines restricting antipsychotic prescription in this population, the use of antipsycotics remains common. Many published studies only report short-term outcomes, are restricted to examining mortality and stroke risk or have other limitations. The aim of this study was to assess adverse outcomes associated with the use of antipsychotics in older people living with dementia in Wales (UK)...

BACKGROUND: ACEII transcription factor plays a significant role in regulating the expression of cellulase and hemicellulase encoding genes. Apart from ACEII, transcription factors such as XYR1, CRE1, HAP2/3/5 complex and ACEI function in a coordinated pattern for regulating the gene expression of cellulases and hemicellulases. Studies have demonstrated that ACEII gene deletion results in decreased total cellulase and xylanase activities with reduced transcript levels of lignocellulolytic enzymes...

BACKGROUND: Posttraumatic enophthalmos is a relatively common problem following orbitozygomatic fractures. However, inadequate long-term results are frequently observed due to the difficulty of performing intraoperative fine adjustments to soft-tissue volume and orbital size and gradual absorption of some grafted materials. Here, the authors describe an efficient method of enophthalmos correction using sliced costochondral bone and cartilage combination grafts. METHODS: From 2005 to 2011, the authors corrected enophthalmos in 12 patients using sliced costochondral grafts...

Nonunion of femoral shaft fracture is an uncommon complication after closed intramedullary nailing which often leading to nail breakage. Removal of the broken femoral nail with closed manner is a challenging procedure for orthopedic surgeons. The removal technique with the T-reamer is a closed method, which does not require either a nonunion site opening or knee exposing. We reported 3 cases of nonunion femoral shaft with broken slotted and non-slotted hollow nail which were successfully removed without any complication...

Stainless steel alloys, including 316L, find use in orthopaedics, commonly as fracture fixation devices. Invasive procedures involved in the placement of these devices will provoke a local inflammatory response that produces hydrogen peroxide (H2O2) and an acidic environment surrounding the implant. This study assessed the influence of a simulated inflammatory response on the corrosion of 316L stainless steel. Samples were immersed in an electrolyte representing either normal or inflammatory physiological conditions...

The effects of hydraulic fracturing (HF) flowback and produced water (HF-FPW), a complex saline mixture of injected HF fluids and deep formation water that return to the surface, was examined in rainbow trout (Oncorhynchus mykiss). Exposure to HF-FPWs resulted in significant induction of ethoxyresorufin-O-deethylase (EROD) activity in both liver and gill tissues. Increased lipid peroxidation via oxidative stress was also detected by thiobarbituric acid reactive substances (TBARS) assay. The mRNA expressions of a battery of genes related to biotransformation, oxidative stress, and endocrine disruption were also measured using quantitative real-time polymerase chain reaction (Q-RT-PCR)...
