| 1 | Role of the Ilizarov non-free bone plasty in the management of long bone defects and nonunion: Problems solved and unsolved显示文摘BACKGROUND Ilizarov non-free bone plasty is a method of distraction osteogenesis using the Ilizarov apparatus for external fixation which originated in Russia and was disseminated across the world. It has been used in long bone defect and nonunion management along with free vascularized grafting and induced membrane technique. However, the shortcomings and problems of these methods still remain the issues which restrict their overall use.AIM To study the recent available literature on the role of Ilizarov non-free bone plasty in long bone defect and nonunion management, its problems and the solutions to these problems in order to achieve better treatment outcomes.METHODS Three databases(Pub Med, Scopus, and Web of Science) were searched for literature sources on distraction osteogenesis, free vascularized grafting and induced membrane technique used in long bone defect and nonunion treatment within a five-year period(2015-2019). Full-text clinical articles in the English language were selected for analysis only if they contained treatment results,complications and described large patient samples(not less than ten cases for congenital, post-tumor resection cases or rare conditions, and more than 20 cases for the rest). Case reports were excluded.RESULTS Fifty full-text articles and reviews on distraction osteogenesis were chosen.Thirty-five clinical studies containing large series of patients treated with this method and problems with its outcome were analyzed. It was found that distraction osteogenesis techniques provide treatment for segmental bone defects and nonunion of the lower extremity in many clinical situations, especially in complex problems. The Ilizarov techniques treat the triad of problems simultaneously(bone loss, soft-tissue loss and infection). Management of tibial defects mostly utilizes the Ilizarov circular fixator. Monolateral fixators are preferable in the femur. The use of a ring fixator is recommended in patients with an infected tibial bone gap of more than 6 cm. High rates of successful treatment were reported by the authors that ranged from 77% to 100% and depended on the pathology and the type of Ilizarov technique used. Hybrid fixation and autogenous grafting are the most applicable solutions to avoid after-frame regenerate fracture or deformity and docking site nonunion.CONCLUSION The role of Ilizarov non-free bone plasty has not lost its significance in the treatment of segmental bone defects despite the shortcomings and treatment problems encountered. | Dmitry Y Borzunov Sergei N Kolchin Tatiana A Malkova | 2020 | World Journal of Orthopedics2020，11，6： | 13 |
| 2 | Rheumatic manifestations of inflammatory bowel disease显示文摘This article reviews the literature concerning rheu-matic manifestations of inflammatory bowel disease (IBD),including common immune-mediated pathways,frequency,clinical course and therapy. Musculoskel-etal complications are frequent and well-recognized manifestations in IBD,and affect up to 33% of pa-tients with IBD. The strong link between the bowel and the osteo-articular system is suggested by many clinical and experimental observations,notably in HLA-B27 transgenic rats. The autoimmune pathogenic mechanisms shared by IBD and spondyloarthropathies include genetic susceptibility to abnormal antigen pre-sentation,aberrant recognition of self,the presence of autoantibodies against specific antigens shared by the colon and other extra-colonic tissues,and increased intestinal permeability. The response against microor-ganisms may have an important role through molecular mimicry and other mechanisms. Rheumatic mani-festations of IBD have been divided into peripheral arthritis,and axial involvement,including sacroiliitis,with or without spondylitis,similar to idiopathic anky-losing spondylitis. Other periarticular features can oc-cur,including enthesopathy,tendonitis,clubbing,peri-ostitis,and granulomatous lesions of joints and bones.Osteoporosis and osteomalacia secondary to IBD and iatrogenic complications can also occur. The manage-ment of the rheumatic manifestations of IBD consists of physical therapy in combination with local injection of corticosteroids and nonsteroidal anti-inflammatory drugs; caution is in order however,because of their possible harmful effects on intestinal integrity,perme-ability,and even on gut inflammation. Sulfasalazine,methotrexate,azathioprine,cyclosporine and lefluno-mide should be used for selected indications. In some cases,tumor necrosis factor-α blocking agents should be considered as first-line therapy. | Tatiana Sofía Rodríguez-Reyna Cynthia Martínez-Reyes Jesús Kazúo Yamamoto-Furusho | 2009 | World Journal of Gastroenterology2009，15，44： | 11 |
| 3 | International recognition of the Ilizarov bone reconstruction techniques: Current practice and research (dedicated to 100th birthday of G. A. Ilizarov)显示文摘The Ilizarov method is one of the current methods used in bone reconstruction.It originated in the middle of the past century and comprises a number of bone reconstruction techniques executed with a ring external fixator developed by Ilizarov GA.Its main merits are viable new bone formation through distraction osteogenesis,high union rates and functional use of the limb throughout the course of treatment.The study of the phenomenon of distraction osteogenesis induced by tension stress with the Ilizarov apparatus was the impetus for advancement in bone reconstruction surgery.Since then,the original method has been used along with a number of its modifications developed due to emergence of new fixation devices and techniques of their application such as hexapod external fixators and motorized intramedullary lengthening nails.They gave rise to a relatively new orthopedic subspecialty termed“limb lengthening and reconstruction surgery”.Based on a comprehensive literature search,we summarized the recent clinical practice and research in bone reconstruction by the Ilizarov method with a special focus on its modification and recognition by the world orthopedic community.The international influence of the Ilizarov method was reviewed in regard to the origin country of the authors and journal’s rating.The Ilizarov method and other techniques based on distraction osteogenesis have been used in many countries and on all populated continents.It proves its international significance and confirms the greatest contribution of Ilizarov GA to bone reconstruction surgery. | Tatiana A Malkova Dmitry Y Borzunov | 2021 | World Journal of Orthopedics2021，12，8： | 8 |
| 4 | Tumor infiltrating lymphocytes in triple negative breast cancer receiving neoadjuvant chemotherapy显示文摘AIM To determine influence of neoadjuvant-chemotherapy(NAC) over tumor-infiltrating-lymphocytes(TIL) intriple-negative-breast-cancer(TNBC).METHODS TILs were evaluated in 98 TNBC cases who came to Instituto Nacional de Enfermedades Neoplasicas from 2005 to 2010. Immunohistochemistry staining for CD3, CD4, CD8 and FOXP3 was performed in tissue microarrays(TMA) sections. Evaluation of H/E in full-face and immunohistochemistry in TMA sections was performed in pre and post-NAC samples. STATA software was used and P value < 0.05 was considered statistically significant. RESULTS Higher TIL evaluated in full-face sections from pre-NAC tumors was associated to pathologic-complete-response(pCR)(P = 0.0251) and outcome(P = 0.0334). TIL evaluated in TMA sections showed low level of agreement with full-face sections(ICC = 0.017-0.20) and was not associated to pCR or outcome. TIL in post-NAC samples were not associated to response or outcome. PostNAC lesions with pC R had similar TIL levels than those without pCR(P = 0.6331). NAC produced a TIL decrease in full-face sections(P < 0.0001). Percentage of TIL subpopulations was correlated with their absolute counts. Higher counts of CD3, CD4, CD8 and FOXP3 in pre-NAC samples had longer disease-free-survival(DFS). Higher counts of CD3 in pre-NAC samples had longer overallsurvival. Higher ratio of CD8/CD4 counts in pre-NAC was associated with pCR. Higher ratio of CD4/FOXP3 counts in pre-NAC was associated with longer DFS. Higher counts of CD4 in post-NAC samples were associated with pCR.CONCLUSION TIL in pre-NAC full-face sections in TNBC are correlated to longer survival. TIL in full-face differ from TMA sections, absolute count and percentage analysis of TIL subpopulation closely related. | Carlos A Castaneda Elizabeth Mittendorf Sandro Casavilca Yun Wu Miluska Castillo Patricia Arboleda Teresa Nunez Henry Guerra Carlos Barrionuevo Ketty Dolores-Cerna Carolina Belmar-Lopez Julio Abugattas Gabriela Calderon Miguel De La Cruz Manuel Cotrina Jorge Dunstan Henry L Gomez Tatiana Vidaurre | 2016 | World Journal of Clinical Oncology2016，7，5： | 6 |
| 5 | Ilizarov 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 | 2022 | World Journal of Orthopedics2022，13，3： | 6 |
| 6 | Thiopurine-methyltransferase variants in inflammatory bowel disease:Prevalence and toxicity in Brazilian patients显示文摘AIM:To analyze the prevalence of thiopurine-methyltransferase(TPMT)genotypes and their associationwith drug toxicity in inflammatory bowel disease(IBD)patients from southeastern Brazil.METHODS:A total of 219 consecutive patients with IBD,of which 146 had Crohn’s disease and 73 had ulcerative colitis,regularly seen at the outpatient unit of the Division of Gastroenterology at the University Hospital Pedro Ernesto of the State University of Rio de Janeiro,a tertiary referral center,were enrolled in this study from February 2009 to January 2011.We analyzed the presence of major TPMT genetic variants(TPMT*2,*3A,*3C)in IBD patients by means of a specific allele and RFLP-PCR.Genomic DNA was isolated from peripheral blood leukocytes by proteinase-K/Sodium Dodecyl Sulfate digestion and phenol-chloroform extraction.TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes were detected by real-time polymerase chain reaction followed by direct sequencing with specific primers.Clinical data were systematically recorded,and correlated with the genotype results.RESULTS:The distribution of the selected TPMT gene polymorphism TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes was 3.6%,5.4%,and 7.7%of the patients,respectively.Among the side effects recorded from patients taking azathioprine,14 patients presented with pancreatitis and/or an elevation of pancreatic enzymes,while 6 patients had liver toxicity,and 2 patients exhibited myelosuppression/neutropenia.TPMT polymorphisms were detected in 37/219 patients(8 heterozygous for*2,11 heterozygous for*3A,and 18 heterozygous for*3C).No homozygotic polymorphisms were found.Despite the prevalence of the TPMT*3C genotype,no differences among the genotype frequencies were significant.Although no association was detected regarding myelotoxicity or hepatotoxicity,a trend towards the elevation of pancreatic enzymes was observed for TPMT*2 and TPMT*3C genotypes.CONCLUSION:The prevalence of TPMT genotypes was high among Brazilian patients.Variants genes*2and*3C may be associated with azathioprine pancreatic toxicity in a IBD southeastern Brazilian population. | Ana Teresa P Carvalho Barbara C Esberard Renata S B Fróes Davy C M Rapozo Ana B Grinman Tatiana A Simo Juliana C V C Santos Antonio José V Carneiro Luis Felipe Ribeiro-Pinto Heitor S P de Souza | 2014 | World Journal of Gastroenterology2014，20，12： | 3 |
