简介：AbstractThe aim of this study was to evaluate the performance of an assay using dried plasma spot (DPS) and dried blood spot (DBS) samples for the serological detection of anti-hepatitis C virus (HCV) antibodies. Between January and July 2019, plasma, DPS and DBS specimens were collected from individuals at high-risk for HCV infection. Samples were tested for anti-HCV by ELISA, and the performance of DPS and DBS specimens was examined using results from the plasma testing, as the standard. Blood samples were collected from 329 persons, including 129 men who have sex with men and 200 intravenous drug users. Results from the plasma testing indicated that 118 samples (59.0%) were HCV positive. Data from the DPS sample testing showed sensitivity as 99.2% (95% confidence interval [CI]: 0.95-1.00) and specificity as 100% (95% CI: 0.98-1.00) for HCV detection, with Kappa of 99.3% (95% CI: 0.98-1.00) while in DBS sample testing the sensitivity as 98.3% (95% CI: 0.93-1.00) and specificity as 100% (95% CI: 0.98-1.00), with Kappa of 98.7% (95% CI: 0.97-1.00), respectively. Spearman’s correlation coefficients for the comparisons between plasma and DPS specimen, plasma and DBS specimens, DPS and DBS specimens were 0.857, 0.750, and 0.739, respectively. Compared with the results in plasma, 1 sample was not detected using the DPS specimens, and 2 samples were failed for the positive detection, using the DBS specimens. Both DPS and DBS samples were promising alternatives to plasma, for the detection of anti-HCV antibodies.

简介：AbstractPurpose:Treatment of distal tibia fractures poses significant challenge to orthopedic surgeon because of poor blood supply and paucity of soft tissue coverage. There is considerable controversy regarding the superior option of treatment for distal tibia fracture between the minimally invasive percutaneous plate osteosynthesis (MIPPO) technique and intramedullary interlocking (IMIL) nailing for extra-articular distal tibia fractures. The aim of our study is to compare the functional outcome between the two treatment methods.Methods:This was the prospective comparative study of 100 patients with distal third tibia fractures divided into two groups. The first group of patients were treated with MIPPO technique while the second group of patients were managed by IMIL nailing. Patients were followed up in outpatient department to assess the functional outcomes, malunion, delayed union, nonunion, superficial and deep infection between the two groups. Statistical analyses were performed using the SPSS software (version 16.0).Results:Average malunion (degrees) in the MIPPO group was 5 (3—7) ± 1.41 vs. 10.22 (8—14) ± 2.04 in the IMIL group (p= 0.001). Similarly postoperative knee pain in the IMIL group was 10% vs. 2% in the MIPPO group (p= 0.001). In terms of superficial infection and nonunion, the results were 8% vs. 4% and 2% vs. 6% for the MIPPO and IMIL group, respectively (p= 0.001).Conclusion:Both procedures have shown the reliable method of fixation for distal extra-articular tibia fractures preserving the soft tissue, bony vascularity and fracture hematoma that provide a favourable biological environment for fracture healing. Considering the results of the study, we have slightly more preference for the MIPPO technique.

简介：AbstractPurpose:Comminuted intraarticular distal radial fractures are difficult to treat conservatively and require operative treatment. This study compared the functional outcomes between variable angle volar plating and external fixator with K-wire augmentation in open reduction and internal fixation.Methods:A total of 62 adult patients with comminuted intraarticular distal radius fracture were randomized into 2 groups: volar plate group and external fixator group. These patients aged between 18 and 60 years had unilateral fractures, and agreed to be included in the study. Patients with a history of fracture, bilateral fracture, associated other injuries, delayed injury for more than 2 weeks, open fracture, pre-existing arthrosis or disability, psychiatric illness and pathological fracture were excluded. Patients were followed up at 6 weeks, 3 months, 6 months and 1 year. The assessment of pain, functional activity, range of motion and grip strength was done at each stage of follow-up. The pain and functional activities were assessed by patient rated wrist evaluation (PRWE) score and disabilities of the arm, shoulder and hand (DASH) score.Results:Patients in volar plate group had superior PRWE score and DASH score at each stage of follow-up. At 1 year follow-up, the mean PRWE score were 7.48 for volar plate group and 7.35 for external fixator group; while the mean DASH score was 4.65 for volar plate group and 5.61 for external fixator group. They had better flexion and extension range of movement. They also had better pronation and supination range of motion at initial follow-up, however the difference get attenuated by 1 year. Volar plate group had significantly better grip strength than external fixator group. Complication rates were higher in external fixation group.Conclusion:Fixation with variable angle volar plate results in early wrist mobilization, better range of movement, less pain and disability and early return of function.
