简介：AbstractPurpose:Common peroneal nerve palsy is quite disabling and every effort should be made to prevent its injury during the treatment.Methods:We retrospectively reviewed the prospectively collected data of 7 cases of tibial plateau fractures in association with proximal fibula fracture from January 2019 to September 2019 who presented to emergency room of our hospital.Results:In addition to fibular neck fracture, the first case had type 6 tibial plateau displaced fracture and the second case had displaced acetabular fracture with instability of knee with tibial tuberosity avulsion. common peroneal nerve palsy developed following application of distal tibial skeletal traction in both the cases. Other 6 such cases remained neurologically intact as traction was not applied to them.Conclusion:Such iatrogenic complication could have been prevented if the injury pattern of "concomitant medial and lateral columns" of the proximal leg is kept in mind by the treating surgeon before applying skeletal traction.

简介：AbstractPurpose:This study evaluated the angular kinematic and moment of the ankle and foot during shod walking and barefoot walking in individuals with unilateral chronic ankle instability (CAI).Methods:Recreational soccer players with unilateral CAI were recruited for this cross sectional study conducted between January and August 2019. A total of 40 participants were screened for eligibility but only 31 met the inclusion criteria based on the methods of Delahunt et al and Gribble et al. Except for 3 participants not attending the evaluation session, 28 participants were finally included. A three dimensional motion analysis system made up of ProReflex motion capture unit and an AMTIb Kistler force plate, embedded in the middle of nine meter walkway, were used to assess the ankle and foot angles and moment during shod walking and barefoot walking conditions. A Statistical Package for Social Sciences (version 20.0) was used to analyze data.Results:During shod walking, the ankle joint plantar-flexion range of motion (ROM) at 10% of the gait cycle (GC) and dorsiflexion ROM at 30% of the GC were significantly higher than those during barefoot walking for both feet (p = 0.001, 0.001, 0.027, and 0.036 respectively). The inversion ROM during shod walking was significantly higher than that during barefoot walking for both feet at 10% and 30% of the GC (p = 0.001. 0.001, 0.001, and 0.042 respectively). At 10% of the GC, the eversion moment was significantly higher between barefoot and shod walking for both feet (both p = 0.001). At 30% of the GC, there was no significant difference between shod and barefoot walking plantar-flexion moment of both feet (p = 0.975 and 0.763 respectively), and the eversion moment of both feet (p = 0.116 and 0.101 respectively).Conclusion:At the early stance, shod walking increases the ankle plantar-flexion and foot inversion ROM, and decreases the eversion moment for both feet in subjects with unilateral CAI. Therefore, the foot wearing condition should be considered during evaluation of ankle and foot kinematics and kinetics.

简介：AbstractFoot-and-mouth disease virus (FMDV), swine vesicular disease virus (SVDV) and classical swine fever virus (CSFV) all cause important animal diseases. FMDV affects many different cloven-hoofed animals, whereas SVDV and CSFV are restricted to domestic and feral pigs together with wild boar. Europe is normally free of these diseases, but occasionally outbreaks happen, which can cause huge economic losses. Handling of these viruses, in particular FMDV and CSFV, is only allowed within high containment laboratories and stables. Periodically such facilities need to be decommissioned for repair or closing down, which is done by cleaning and chemical disinfection, followed by fumigation due to residual risk from virus on surfaces in inaccessible places. However, building materials in older laboratories or stables that have housed infected animals may not be well-suited for fumigation. Heat treatment is another way of inactivating viruses. In this study, we have determined the survival of infectivity in air-dried virus samples on glass and plastic surfaces incubated at room temperature or heated to 70 °C for 1, 2, 3, 5 and 7 days. Each of the tested viruses was inactivated to below the limit of detection after 24 h or 48 h of incubation at 70 °C; in contrast, some of these viruses were still infectious after 7 days of incubation at room temperature. This study provides important information that can be used in relation to decontamination of buildings and in risk-assessments.
