1Ilizarov bone transport combined with the Masquelet technique for bone defects of various etiologies (preliminary results)显示文摘BACKGROUND The Ilizarov bone transport(IBT)and the Masquelet induced membrane technique(IMT)have specific merits and shortcomings,but numerous studies have shown their efficacy in the management of extensive long-bone defects of various etiologies,including congenital deficiencies.Combining their strong benefits seems a promising strategy to enhance bone regeneration and reduce the risk of refractures in the management of post-traumatic and congenital defects and nonunion that failed to respond to other treatments.AIM To combine IBT and IMT for the management of severe tibial defects and pseudarthrosis,and present preliminary results of this technological solution.METHODS Seven adults with post-traumatic tibial defects(subgroup A)and nine children(subgroup B)with congenital pseudarthrosis of the tibia(CPT)were treated with the combination of IMT and IBT after the failure of previous treatments.The mean number of previous surgeries was 2.0±0.2 in subgroup A and 3.3±0.7 in subgroup B.Step 1 included Ilizarov frame placement and spacer introduction into the defect to generate the induced membrane which remained in the interfragmental gap after spacer removal.Step 2 was an osteotomy and bone transport of the fragment through the tunnel in the induced membrane,its compression and docking for consolidation without grafting.The outcomes were retrospectively studied after a mean follow-up of 20.8±2.7 mo in subgroup A and 25.3±2.3 mo in subgroup B.RESULTS The“true defect”after resection was 13.3±1.7%in subgroup A and 31.0±3.0%in subgroup B relative to the contralateral limb.Upon completion of treatment,defects were filled by 75.4±10.6%and 34.6±4.2%,respectively.Total duration of external fixation was 397±9.2 and 270.1±16.3 d,including spacer retention time of 42.4±4.5 and 55.8±6.6 d,in subgroups A and B,respectively.Bone infection was not observed.Postoperative complications were several cases of pin-tract infection and regenerate deformity in both subgroups.Ischemic regeneration was observed in two cases of subgroup B.Complications were corrected during the course of treatment.Bone union was achieved in all patients of subgroup A and in seven patients of subgroup B.One non-united CPT case was further treated with the Ilizarov compression method only and achieved union.After a follow-up period of two to three years,refractures occurred in four cases of united CPT.CONCLUSION The combination of IMT and IBT provides good outcomes in post-traumatic tibial defects after previous treatment failure but external fixation is longer due to spacer retention.Refractures may occur in severe CPT.Dmitry Y Borzunov Sergey N Kolchin Denis S Mokhovikov Tatiana A Malkova 2022World Journal of Orthopedics2022,13,3:6

4Molecular pathways of liver regeneration:A comprehensive review显示文摘The liver is a unique parenchymal organ with a regenerative capacity allowing it to restore up to 70%of its volume.Although knowledge of this phenomenon dates back to Greek mythology(the story of Prometheus),many aspects of liver regeneration are still not understood.A variety of different factors,including inflammatory cytokines,growth factors,and bile acids,promote liver regeneration and control the final size of the organ during typical regeneration,which is performed by mature hepatocytes,and during alternative regeneration,which is performed by recently identified resident stem cells called“hepatic progenitor cells”.Hepatic progenitor cells drive liver regeneration when hepatocytes are unable to restore the liver mass,such as in cases of chronic injury or excessive acute injury.In liver maintenance,the body mass ratio is essential for homeostasis because the liver has numerous functions;therefore,a greater understanding of this process will lead to better control of liver injuries,improved transplantation of small grafts and the discovery of new methods for the treatment of liver diseases.The current review sheds light on the key molecular pathways and cells involved in typical and progenitor-dependent liver mass regeneration after various acute or chronic injuries.Subsequent studies and a better understanding of liver regeneration will lead to the development of new therapeutic methods for liver diseases.Yana V Kiseleva Sevak Z Antonyan Tatyana S Zharikova Kirill A Tupikin Dmitry V Kalinin Yuri O Zharikov 2021World Journal of Hepatology2021,13,3:2

6Discrimination of ventricular tachycardia and localization of its exit site using surface electrocardiography显示文摘Differential diagnosis of supraventricular tachycardia (SVT) and ventricular tachycardia (VT) is of paramount importance for appropriate patient management. Several diagnostic algorithms for discrimination of VT and SVT based on surface electrocardiogram (ECG) analysis have been proposed. Following established diagnosis of VT,a specific origination tachycardia site can be supposed according to QRS complex characteristics. This review aims to cover comprehensive and comparative description of the main VT diagnostic algorithms and to present ECG characteristics which permit to suggest the most common VT origination sites.Heber Ivan Condori Leandro Dmitry S Lebedev Evgeny N Mikhaylov 2019Journal of Geriatric Cardiology2019,16,4:2
