ABSTRACT

Objetivo: apresentar o relato de duas pacientes com agenesias dentárias em que cinco dentes autotransplantados foram utilizados como modalidade de tratamento. Além disso, objetiva-se mostrar questões sobre a técnica cirúrgica, suas indicações e previsibilidade. Relato de caso: Neste estudo, foram relatados 5 casos de autotransplante dentário em duas pacientes jovens, em que a equipe realizou os procedimentos e o acompanhamento clínico e radiográfico por 5 e 7 anos. Devido à alta sensibilidade da técnica, foram seguidos princípios previamente estabelecidos na literatura envolvendo o autotransplante dentário. Durante o período de acompanhamento, os dentes se mantiveram em posição e em função e as pacientes não apresentavam queixas associadas. Considerações finais: a técnica do autotransplante dentário, quando bem indicada e executada, é capaz de promover resultados bastante satisfatórios, sendo uma ótima alternativa reabilitadora, com taxas de sucesso elevadas e custos reduzidos. No entanto, critérios em relação aos sítios doadores e receptores e a habilidade do cirurgião devem ser levados em conta para o sucesso do técnica.


Objective: presenting the report of two patients with tooth agenesis in which five autotransplanted teeth were used as a treatment modality. Furthermore, the aim is to show questions about the surgical technique and its indications and predictability. Case report: In this study, 5 cases of dental autotransplantation were reported in two young patients, in which the team performed procedures and had clinical and radiographic follow-up for 5 and 7 years. Due to the high sensitivity of the technique, principles previously established in the literature involving dental autotransplantation were followed. During the follow-up period, the teeth remained in position and function and the patients had no associated complaints. Final considerations: the dental autotransplantation technique, when well indicated and executed, is capable of achieving very satisfactory results, being a great rehabilitative alternative, with high success rates and reduced costs. However, criteria regarding donor and receptor sites and the surgeon's skill must be taken into account for the success of the technique.

ABSTRACT

Introduction: The use of enamel matrix-derived proteins (EMD) has increased in recent years due to their tissue-inducing properties that support periodontal regeneration. This study is an overview of systematic reviews with FRISBEE methodology on the use of EMD alone or combined with autologous bone graft materials (BGM) in the treatment of intrabony defects. Materials and Methods: A systematic search in the Epistemonikos database was performed. RevMan 5.3 and GRADEpro were used for data analysis and presentation Results: Four systematic reviews and two clinical trials were identified. All studies analysed change in probing depth, clinical attachment level, gingival margin level and bone defect depth (all changes in favour of EMD+BGM groups: mean difference (MD): 0.37 mm more, MD: 0.7 mm more, MD: 0.3 mm less, MD: 0.75 more, respectively). Conclusions: Adding autologous bone graft to EMD to treat intrabony defects showed better results, but not a relevant clinical difference compared to the use of EMD alone.


Introducción: El uso de proteínas derivadas de la matriz del esmalte (EMD) ha aumentado en los últimos años debido a sus propiedades inductoras de tejidos que apoyan la regeneración periodontal. Este estudio es una revisión sistemática de revisiones sistemáticas utilizando metodología FRISBEE sobre el uso de EMD solo o combinado con materiales injerto óseo autólogo (BGM) en el tratamiento de defectos intraóseos. Materiales y Métodos: Se realizó una búsqueda sistemática en la base de datos Epistemonikos. Se utilizaron RevMan 5.3 y GRADEpro para el análisis y la presentación de los datos. Resultados: Se identificaron cuatro revisiones sistemáticas y dos ensayos clínicos. Todos los estudios analizaron el cambio en la profundidad de sondaje, el nivel de inserción clínica, el nivel del margen gingival y la profundidad del defecto óseo (todos los cambios a favor de los grupos EMD+BGM: MD: 0,37 mm más, media de diferencia (MD): 0,7 mm más, MD: 0,3 mm menos, MD: 0,75 más, respectivamente). Conclusión: La adición de injerto óseo autólogo a la EMD para tratar defectos intraóseos mostró mejores resultados, pero no una diferencia clínica relevante en comparación con el uso de la EMD sola.

ABSTRACT

ABSTRACT Objective Compare the thickness of conjunctival autografts in pterygium surgery using the Moscovici dissection technique with manual dissection and assess the difficulty of the techniques. Methods In this randomized clinical trial, 30 eyes of 30 patients undergoing pterygium surgery were divided into the Moscovici Dissection Technique Group and the Manual Dissection Group. The patients were treated at the Hospital Oftalmológico Visão Laser (Santos, São Paulo, Brazil). Optical coherence tomography was performed to measure graft thickness three months postoperatively. Three images were obtained from each eye, and three measurements were taken at a distance of 1.5mm perpendicular to the limbus in each capture. The surgeon graded the difficulty of obtaining the graft with the technique performed from one (lowest difficulty) to four (highest difficulty). Results We found statistically significant difference between the difficulty of the two techniques and the mean conjunctival autograft thickness in the two groups (p=0.01 e p=0.05, respectively). The average difficulty rating for the Moscovici Dissection Technique Group (Air Group) was 1.47, while that for the Manual Dissection Group (MD group) was 2.20. The mean thickness of the three measurements was 252µ in the Air Group and 298µ in the MD Group, with medians of 250µ and 278µ, respectively. Conclusion Our study showed that the Moscovici technique results in thinner grafts and can be performed with greater surgical ease.


RESUMO Objetivo Comparar a espessura de autoenxertos conjuntivais em cirurgia de pterígio utilizando a técnica de dissecção de Moscovici com a de dissecção manual e avaliar a dificuldade das técnicas. Métodos Neste ensaio clínico randomizado, 30 olhos de 30 pacientes submetidos à cirurgia de pterígio foram divididos em um Grupo de Técnica de Dissecção de Moscovici e um Grupo de Dissecção Manual. Os pacientes foram tratados e avaliados no Hospital Oftalmológico Visão Laser (Santos, São Paulo, Brasil). A tomografia de coerência óptica foi realizada para medir a espessura do enxerto 3 meses após a cirurgia. Três imagens foram obtidas de cada olho, e três medidas foram realizadas a uma distância de 1,5mm perpendicular ao limbo em cada captura. O cirurgião classificou a dificuldade de obtenção do enxerto com a técnica realizada de um (menor dificuldade) para quatro (maior dificuldade). Resultados Encontramos diferenças estatisticamente significantes entre a dificuldade das duas técnicas e a espessura média do autoenxerto conjuntival nos dois grupos (p=0,01 e p=0,05, respectivamente). A classificação média de dificuldade para o Grupo de Técnica de Dissecção de Moscovici foi de 1,47, enquanto a do Grupo de Dissecção Manual foi de 2,20. A espessura média das três medidas foi de 252μ no Grupo de Técnica de Dissecção de Moscovici e de 298μ no Grupo de Dissecção Manual, com medianas de 250μ e 278μ, respectivamente. Conclusão Nosso estudo mostrou que a técnica de Moscovici resulta em enxertos mais finos e pode ser realizada com maior facilidade cirúrgica.

ABSTRACT

Special Article Introduction Hematopoietic stem cell transplantation is the only curative treatment for many disorders and international data shows a growing trend. Method We aimed to evaluate the temporal trends in HSCT transplant rates in Argentina. A time-series analysis was performed for the period 2009 to 2018 using the national database from the National Central Coordinating Institute for Ablations and Implants. Crude and standardized transplant rates were calculated. A permutation joinpoint regression model analysis was used to identify significant changes over time. Results Altogether, 8,474 transplants were reported to INCUCAI by 28 centers (autologous 67.5%); the main indication was multiple myeloma (30%). The WHO age-sex standardized HSCT rates for the entire country were 153.3 HSCT/10 million inhabitants (95% CI 141.7-165.8) in 2009 and 260.1 HSCT/10 million inhabitants (95% CI 245.5-275.5) in 2018. There was a large gap in HSCT rates among the states and regions. The transplant rate was higher for autologous transplants throughout the years. Within the allogeneic group, the related donor transplant rate was higher than the unrelated donor transplant rate. The joinpoint regression analysis of HSCT rates for the whole country over time showed an observed annual percentage change of 6.3% (95% CI 5.4-7.3; p< 0.01). No changes were observed for unrelated donors during the study period. Conclusions Age-sex standardized HSCT rates in Argentina are increasing, mainly due to autologous and family donor allogeneic transplants. A wide variation across the country was found, demonstrating differences in the access to transplantation among Argentine regions.

ABSTRACT

OBJECTIVE@#To investigate the association between the expression level of platelet-activating factor acetylhydrolase 1B3 (PAFAH1B3 ) gene in bone marrow CD138+ cells of patients with multiple myeloma (MM) treated with autologous hematopoietic stem cell transplantation (AHSCT) and the prognosis within 2 years.@*METHODS@#147 MM patients treated with AHSCT in The First and The Second Affiliated Hospital of Nantong University from May 2014 to May 2019 were included in the study. Expression level of PAFAH1B3 mRNA in bone marrow CD138+ cells of the patients was detected. Patients with disease progression or death during 2 years of follow-up were included in progression group, and the rest were included in good prognosis group. After comparing the clinical data and PAFAH1B3 mRNA expression levels of the two groups, the patients were divided into high PAFAH1B3 expression group and low PAFAH1B3 expression group based on the median PAFAH1B3 mRNA expression level of the enrolled patients. Progression-free survival rate (PFSR) between the two groups was compared by the Kaplan-Meier method. The related factors of prognosis within 2 years were analyzed by univariate analysis and multivariate COX regression analysis.@*RESULTS@#At the end of follow-up, there were 13 patients lost to follow-up. Finally, 44 patients were included in the progression group and 90 patients were included in the good prognosis group. Age in the progression group was higher than that in the good prognosis group, the proportion of patients with CR+VGPR after transplantation in the progression group was lower than that in the good prognosis group, and there was a statistical difference between two groups in the cases distribution of ISS stage (all P<0.05). PAFAH1B3 mRNA expression level and the proportion of patients with LDH>250U/L in the progression group were higher than those in the good prognosis group, and platelet count in the progression group was lower than that in the good prognosis group (all P<0.05). Compared with the low PAFAH1B3 expression group, the 2-year PFSR of the high PAFAH1B3 expression group was significantly lower (log-rank χ2=8.167, P=0.004). LDH>250U/L (HR=3.389, P=0.010), PAFAH1B3 mRNA expression (HR=50.561, P=0.001) and ISS stage Ⅲ(HR=1.000, P=0.003) were independent risk factors for prognosis in MM patients, and ISS stage Ⅰ (HR=0.133, P=0.001) was independent protective factor.@*CONCLUSION@#The expression level of PAFAH1B3 mRNA in bone marrow CD138+ cells is related to the prognosis of MM patients treated with AHSCT, and detecting PAFAH1B3 mRNA expression can bring some information for predicting PFSR and prognostic stratification of patients.

ABSTRACT

OBJECTIVES@#To investigate the effectiveness of high-dose chemotherapy combined with autologous hematopoietic stem cell transplantation (ASCT) in the treatment of children with high-risk neuroblastoma (NB).@*METHODS@#A retrospective analysis was performed on 29 children with high-risk NB who were admitted to Shanghai Children's Hospital and were treated with high-dose chemotherapy combined with ASCT from January 2013 to December 2021, and their clinical features and prognosis were analyzed.@*RESULTS@#Among the 29 children treated by high-dose chemotherapy combined with ASCT, there were 18 boys (62%) and 11 girls (38%), with a median age of onset of 36 (27, 59) months. According to the International Neuroblastoma Staging System, 6 children (21%) had stage III NB and 23 children (79%) had stage IV NB, and the common metastatic sites at initial diagnosis were bone in 22 children (76%), bone marrow in 21 children (72%), and intracalvarium in 4 children (14%). All 29 children achieved reconstruction of hematopoietic function after ASCT. After being followed up for a median time of 25 (17, 45) months, 21 children (72%) had continuous complete remission and 8 (28%) experienced recurrence. The 3-year overall survival rate and event-free survival rate were 68.9%±16.1% and 61.4%±14.4%, respectively. Presence of bone marrow metastasis, neuron-specific enolase ≥370 ng/mL and positive bone marrow immunophenotyping might reduce the 3-year event-free survival rate (P<0.05).@*CONCLUSIONS@#Children with high-risk NB who have bone marrow metastasis at initial diagnosis tend to have a poor prognosis. ASCT combined with high-dose chemotherapy can effectively improve the prognosis of children with NB with a favorable safety profile.

ABSTRACT

OBJECTIVE@#To provide an overview of the incidence of knee donor -site morbidity after autologous osteochondral mosaicplasty.@*METHODS@#A comprehensive search was conducted in PubMed, EMbase, Wanfang Medical Network, and CNKI databases from January 2010 to April 20, 2021. Relevant literature was selected based on predefined inclusion and exclusion criteria, and data were evaluated and extracted. The correlation between the number and size of transplanted osteochondral columns and donor-site morbidity was analyzed.@*RESULTS@#A total of 13 literatures were included, comprising a total of 661 patients. Statistical analysis revealed an incidence of knee donor-site morbidity at 8.6% (57/661), with knee pain being the most common complaint, accounting for 4.2%(28/661). There was no significant correlation between the number of osteochondral columns and postoperative donor-site incidence (P=0.424, N=10), nor between the diameter size of osteochondral columns and postoperative donor-site incidence(P=0.699, N=7).@*CONCLUSION@#Autologous osteochondral mosaicplasty is associated with a considerable incidence of knee donor-site morbidity, with knee pain being the most frequent complaint. There is no apparent correlation between donor-site incidence and the number and size of transplanted osteochondral columns. Donors should be informed about the potential risks.

ABSTRACT

OBJECTIVE@#To investigate the feasibility of establishing an anterior cruciate ligament (ACL) reconstruction model using hamstring tendon autograft in cynomolgus monkeys.@*METHODS@#Twelve healthy adult male cynomolgus monkeys, weighing 8-13 kg, were randomly divided into two groups ( n=6). In the experimental group, the ACL reconstruction model of the right lower limb was prepared by using a single bundle of hamstring tendon, and the ACL of the right lower limb was only cut off in the control group. The survival of animals in the two groups was observed after operation. Before operation and at 3, 6, and 12 months after operation, the knee range of motion, thigh circumference, and calf circumference of the two groups were measured; the anterior tibial translation D-value (ATTD) was measured by Ligs joint ligament digital body examination instrument under the loads of 13-20 N, respectively. At the same time, the experimental group underwent MRI examination to observe the graft morphology and the signal/ noise quotient (SNQ) was caculated.@*RESULTS@#All animals survived to the end of the experiment. In the experimental group, the knee range of motion, thigh circumference, and calf circumference decreased first and then gradually increased after operation; the above indexes were significantly lower at 3 and 6 months after operation than before operation ( P<0.05), and no significant difference was found between pre-operation and 12 months after operation ( P>0.05). In the control group, there was no significant change in knee range of motion after operation, showing no significant difference between pre- and post-operation ( P>0.05), but the thigh circumference and calf circumference gradually significantly decreased with time ( P<0.05), and the difference was significant when compared with those before operation ( P<0.05). At 6 and 12 months after operation, the thigh circumference and calf circumference were significantly larger in the experimental group than in the control group ( P<0.05). At 3 and 6 months after operation, the knee range of motion was significantly smaller in the experimental group than in the control group ( P<0.05). Under the loading condition of 13-20 N, the ATTD in the experimental group increased first and then decreased after operation; and the ATTD significantly increased at 3, 6 months after operation when compared with the value before operation ( P<0.05). But there was no significant difference between the pre-operation and 12 months after operation ( P>0.05). There was no significant change in ATTD in the control group at 3, 6, and 12 months after operation ( P>0.05), and which were significantly higher than those before operation ( P<0.05). At each time point after operation, the ATTD was significantly smaller in the experimental group than in the control group under the same load ( P<0.05). The MRI examination of the experimental group showed that the ACL boundary gradually became clear after reconstruction and was covered by the synovial membrane. The SNQ at each time point after operation was significantly higher than that before operation, but gradually decreased with time, and the differences between time points were significant ( P<0.05).@*CONCLUSION@#The ACL reconstruction model in cynomolgus monkey with autogenous hamstring tendon transplantation was successfully established.

ABSTRACT

Objective: To explore the stem cell collection rate and efficacy and safety of patients aged 70 and below with newly diagnosed multiple myeloma (MM) treated with the VRD (bortezomib, lenalidomide and dexamethasone) regimen followed by autologous stem cell transplantation (ASCT). Methods: Retrospective case series study. The clinical data of 123 patients with newly diagnosed MM from August 1, 2018, to June 30, 2020, at the First Affiliated Hospital of Soochow University and Suzhou Hopes Hematology Hospital, who were eligible for VRD regimen sequential ASCT, were collected. The clinical characteristics, efficacy after induction therapy, mobilization regimen of autologous stem cells, autologous stem cell collection rate, and side effects and efficacy of ASCT were retrospectively analyzed. Results: Of the 123 patients, 67 were males. The median patient age was 56 (range: 31-70) years. Patients with IgG, IgA, IgD, and light-chain types accounted for 47.2% (58/123), 23.6% (29/123), 3.2% (4/123), and 26.0% (32/123) of patients, respectively. In addition, 25.2% (31/123) of patients had renal insufficiency (creatinine clearance rate<40 ml/min). Patients with Revised-International Staging System (R-ISS) Ⅲ accounted for 18.2% (22/121) of patients. After induction therapy, the rates of partial response and above, very-good partial response (VGPR) and above, and complete response (CR)+stringent CR were 82.1% (101/123), 75.6% (93/123), and 45.5% (56/123), respectively. Overall, 90.3% (84/93) of patients were mobilized with cyclophosphamide+granulocyte colony-stimulating factor (G-CSF) and 8 patients with G-CSF or G-CSF+plerixafor due to creatinine clearance rate<30 ml/min and one of them was mobilized with DECP (cisplatin, etoposide, cyclophosphamide and dexamethasone)+G-CSF for progressive disease. The rate of autologous stem cell collection (CD34+cells≥2×106/kg) after four courses of VRD regimen was 89.1% (82/92), and the rate of collection (CD34+cells≥5×106/kg) was 56.5% (52/92). Seventy-seven patients treated with the VRD regimen sequential ASCT. All patients had grade 4 neutropenia and thrombocytopenia. Among the nonhematologic adverse events during ASCT, the highest incidence was observed for gastrointestinal reactions (76.6%, 59/77), followed by oral mucositis (46.8%, 36/77), elevated aminotransferases (44.2%, 34/77), fever (37.7%, 29/77), infection (16.9%, 13/77) and heart-related adverse events (11.7%, 9/77). Among the adverse events, grade 3 adverse events included nausea (6.5%, 5/77), oral mucositis (5.2%, 4/77), vomiting (3.9%, 3/77), infection (2.6%, 2/77), elevated blood pressure after infusion (2.6%, 2/77), elevated alanine transaminase (1.3%, 1/77), and perianal mucositis (1.3%, 1/77); there were no grade 4 or above nonhematologic adverse events. The proportion of patients who achieved VGPR and above after VRD sequential ASCT was 100% (75/75), and the proportion of patients who were minimal residual disease-negative (<10-4 level) was 82.7% (62/75). Conclusion: In patients aged 70 and below with newly diagnosed MM treated with VRD induction therapy, the collection rate of autologous stem cells was good, and good efficacy and tolerability were noted after follow-up ASCT.

ABSTRACT

Objective: To evaluate the efficacy and prognosis of orthopedic surgical resection surgery in patients with newly diagnosed multiple myeloma (NDMM). Methods: This retrospective cohort study collected clinical data of patients with NDMM who underwent surgery due to spinal cord compression or pathological long-bone fractures at the Peking Union Medical College Hospital from 1 January 2003 to 31 December 2021. Patients who received biopsy or vertebroplasty/kyphoplasty were excluded and patients with the same degree of bone disease and who did not undergo any surgical intervention were selected as controls. Visual analogue scale (VAS) and physical status (ECOG) scores, progression-free survival (PFS), and overall survival (OS) were compared. Statistical analysis included the χ2-test, t-test, and Kaplan-Meier methods. Results: Baseline data were compared between the surgical group (n=40 with 43 interventions) and the non-surgical group (n=80), and included sex, age, paraprotein type, International Staging System (ISS), number of lytic lesions, cytogenetic abnormalities, first-line treatment, and the proportion of patients receiving autologous stem cell transplantation (ASCT) (all P>0.05). Serum M protein levels in the surgical group were significantly lower than those of the non-surgical group [(21.95±16.44) g/L vs. (36.18±20.85) g/L, P=0.005]. The surgical lesions involved the axial skeleton (79.1%, 34/43) or the extremities (20.9%, 9/43). VAS and ECOG scores improved significantly after surgery (VAS: 2.30±0.80 vs. 6.60±1.50, P<0.001; ECOG: 2.09±0.59 vs. 3.09±0.73, P<0.001). The median follow-up time was 51 months. Kaplan-Meier survival analysis suggested that the median PFS (25 vs. 29 months) and OS (46 vs. 60 months) were comparable between the surgical and non-surgical intervention groups (both P>0.05). Subgroup analysis showed that among patients with ISS Ⅰ or those who had received ASCT, PFS in the surgical group was similar to that of the non-surgical intervention group (both P>0.05), while OS was worse (P=0.005, 0.017). Patients with ISS Ⅱ/Ⅲ scores or without ASCT had similar PFS and OS between the surgical and non-surgical intervention groups (all P>0.05). Cox multivariate analysis suggested that ISS and ASCT were independent prognostic factors for OS (ISS: HR=0.42, 95%CI 0.19-0.93, P=0.031; ASCT: HR=0.41, 95%CI 0.18-0.97, P=0.041), while orthopedic surgery did not influence survival (P=0.233). Conclusion: For patients with NDMM, orthopedic surgical resection decreased bone-related complications and improved quality of life, but did not affect survival.

ABSTRACT

Objective: To summarize the characteristics of patients with newly diagnosed multiple myeloma (NDMM) admitted at Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine. We compared the clinical characteristics and prognoses among patients with non-extramedullary disease (EMD), bone-related extramedullary (EM-B) disease, and extraosseous extramedullary (EM-E) disease and further explored the effects of autologous hematopoietic stem cell transplantation (ASCT) for EMD. Methods: From January 2015 to January 2022, data of 114 patients (22%) with EMD out of 515 patients with NDMM were retrospectively analyzed; 91 (18%) and 23 (4%) patients comprised the EM-B and EM-E groups, respectively. The clinical characteristics of patients in all groups were compared with the Chi-square test. Progression-free survival (PFS) and overall survival (OS) of patients were analyzed by the Kaplan-Meier method. Independent prognostic factors were determined using multivariate Cox proportional hazard model. Results: There were no significant differences in age, gender, ISS stage, light chain, creatinine clearance, cytogenetic risk, 17p deletion, ASCT, and induction regimens among the three groups. Overall, 13% of EM-E patients had IgD-type M protein, which was significantly higher than that in EM-B patients (P=0.021). The median PFS of patients in the non-EMD, EM-B, and EM-E groups was 27.4, 23.1, and 14.0 months; the median OS was not reached, 76.8 months, and 25.6 months, respectively. The PFS (vs non-EMD, P=0.004; vs EM-B, P=0.036) and OS (vs non-EMD, P<0.001; vs EM-B, P=0.002) were significantly worse in patients with EM-E, while those were not significantly different between patients with EM-B and those with non-EMD. In the multivariate analysis, EM-E was an independent prognostic factor for OS in patients with NDMM (HR=8.779, P<0.001) and negatively impacted PFS (HR=1.874, P=0.050). In those who did not undergo ASCT, patients with EM-B had significantly worse OS than those with non-EMD (median 76.8 months vs. not reached, P=0.029). However, no significant difference was observed in the PFS and OS of patients with EM-B and those with non-EMD who underwent ASCT. Conclusions: Compared to patients with either non-EMD or EM-B, those with EM-E had the worst prognosis. EM-E was an independent risk factor for OS in patients with NDMM. ASCT can overcome the poor prognosis of EM-B.

ABSTRACT

Objective: To evaluate the advantages and safety of Plerixafor in combination with granulocyte colony-stimulating factor (G-CSF) in autologous hematopoietic stem cell mobilization of lymphoma. Methods: Lymphoma patients who received autologous hematopoietic stem cell mobilization with Plerixafor in combination with G-CSF or G-CSF alone were obtained. The clinical data, the success rate of stem cell collection, hematopoietic reconstitution, and treatment-related adverse reactions between the two groups were evaluated retrospectively. Results: A total of 184 lymphoma patients were included in this analysis, including 115 cases of diffuse large B-cell lymphoma (62.5%) , 16 cases of classical Hodgkin's lymphoma (8.7%) , 11 cases of follicular non-Hodgkin's lymphoma (6.0%) , 10 cases of angioimmunoblastic T-cell lymphoma (5.4%) , 6 cases of mantle cell lymphoma (3.3%) , and 6 cases of anaplastic large cell lymphoma (3.3%) , 6 cases of NK/T-cell lymphoma (3.3%) , 4 cases of Burkitt's lymphoma (2.2%) , 8 cases of other types of B-cell lymphoma (4.3%) , and 2 cases of other types of T-cell lymphoma (1.1%) ; 31 patients had received radiotherapy (16.8%) . The patients in the two groups were recruited with Plerixafor in combination with G-CSF or G-CSF alone. The baseline clinical characteristics of the two groups were basically similar. The patients in the Plerixafor in combination with the G-CSF mobilization group were older, and the number of recurrences and third-line chemotherapy was higher. 100 patients were mobilized with G-CSF alone. The success rate of the collection was 74.0% for one day and 89.0% for two days. 84 patients in the group of Plerixafor combined with G-CSF were recruited successfully with 85.7% for one day and 97.6% for two days. The success rate of mobilization in the group of Plerixafor combined with G-CSF was substantially higher than that in the group of G-CSF alone (P=0.023) . The median number of CD34(+) cells obtained in the mobilization group of Plerixafor combined with G-CSF was 3.9×10(6)/kg. The median number of CD34(+) cells obtained in the G-CSF Mobilization group alone was 3.2×10(6)/kg. The number of CD34(+) cells collected by Plerixafor combined with G-CSF was considerably higher than that in G-CSF alone (P=0.001) . The prevalent adverse reactions in the group of Plerixafor combined with G-CSF were grade 1-2 gastrointestinal reactions (31.2%) and local skin redness (2.4%) . Conclusion: The success rate of autologous hematopoietic stem cell mobilization in lymphoma patients treated with Plerixafor combined with G-CSF is significantly high. The success rate of collection and the absolute count of CD34(+) stem cells were substantially higher than those in the group treated with G-CSF alone. Even in older patients, second-line collection, recurrence, or multiple chemotherapies, the combined mobilization method also has a high success rate of mobilization.

ABSTRACT

Introduction: Due to the extensive number of studies developed on periodontal pathologies and the clinical need generated to correct bonvze defects, we have carried out an Overview of systematic reviews using the FRISBEE methodology. Material and Methods: Through this study we expect to bridge the knowledge gap generated regarding the clinical question on the effectiveness of autologous bone substitutes and xenografts in maxillary and mandibular bone defects. Results: For this study, we carried out a systematic search in Epistemonikos and PubMed, we included 3 systematic reviews and 5 primary studies included in these reviews to extract their data. We analyzed data using RevMan 5.4. and GRADEpro. Assessed outcomes included: bone gain [MD 0.06 mm lower (0.26 lower to 0.14 higher)] and bone resorption [MD 0.03 mm higher (0.12 lower to 0.18 higher)], where no significant differences were found between the study groups. The certainty of the evidence was moderate for both outcomes. Bone length and bone density outcomes were not measured or reported in the included studies. Conclusion: We concluded that there are no significant clinical differences between the application of autologous bone grafts and xenografts for bone defects correction for the assessed outcomes, therefore, these biomaterials should be applied at the discretion of the clinician and according to the needs and preferences of patients.


Introducción: Debido al extenso número de estudios desarrollados sobre patologías periodontales y a la necesidad clínica generada para corregir defectos óseos, hemos realizado un Overview de revisiones sistemáticas tipo FRISBEE para acortar la brecha de conocimiento generada respecto a la pregunta clínica sobre la efectividad de sustitutos óseos tipo autólogo y xenoinjertos en defectos óseos a nivel maxilar y mandibular. Material y Métodos: Para este estudio realizamos una búsqueda sistemática en Epistemonikos y PubMed, de los cuales incluimos 3 revisiones sistemáticas y 5 estudios primarios incluidos en estas revisiones para extraer sus datos. Los datos fueron analizados a través de RevMan 5.4. Y GRADEpro. Resultados: Los estudios analizaron los desenlaces propuestos: ganancia ósea posterior a la aplicación del injerto óseo [MD 0.06 mm menos (0.26 menos a 0.14 más)] y reabsorción ósea posterior a la aplicación del injerto óseo [MD 0.03 mm más (0.12 menos a 0.18 más)], donde no se encontraron diferencias significativas entre los grupos de estudio. La certeza de la evidencia fue moderada para ambos desenlaces. Los desenlaces longitud ósea y densidad ósea no fueron medidos o reportados en los estudios incluidos. Conclusión: Se concluyó que no hay diferencias que sean clínicamente significativas entre la aplicación de injertos óseos autólogos y xenoinjertos para la corrección de defectos óseos para los desenlaces analizados, por lo que, la aplicación de estos biomateriales queda a criterio del clínico, y de acuerdo a las necesidades y preferencias de los pacientes.

ABSTRACT

A dentina e o osso alveolar apresentam muita semelhança em sua composição. Sendo assim, podemos considerar a utilização da dentina como recurso alternativo nas intervenções que buscam a regeneração tecidual óssea. Objetivo: o presente estudo realizou uma revisão integrativa da literatura sobre o uso da dentina como biomaterial para regeneração óssea. Metodologia: foi realizada uma busca por artigos, nas bases de dados Medline, via PubMed; Scielo, LILACS, BASE, Scopus e Science Direct, queavaliassem ou descrevessem o uso da dentina como biomaterial para regeneração óssea. Foram utilizados os seguintes descritores: "Dentin" AND "Bone Regeneration", sem delimitação de tempo. Os critérios de inclusão foram: estudos clínicos publicados em periódicos, oriundos de dados primários, sobre o uso de dentina como biomaterial. Os critérios de exclusão foram: revisões de literatura, estudos in vitro e em animais, estudos que não fosse possível o acesso na íntegra e estudos que associassem o uso da dentina com outros biomateriais sem que fosse possível relacionar os resultados apenas pelo uso da dentina. Resultados: vinte e três estudos foram selecionados para a presente revisão. As pesquisas demonstraram que há uma heterogenicidade relacionada ao tamanho da partícula de dentina obtida, que pode ser decorrente de diferentes métodos de processamento. Conclusão: a reutilização da dentina como biomaterial pode ser uma alternativa promissora ao enxerto autógeno. Sugere-se, então, que protocolos de processamento da partícula de dentina sejam melhor estabelecidos e estudos longitudinais precisam ser realizados para a garantia de procedimentos seguros, eficazes e práticos.


The dentin and the alveolar bone are very similar in composition, therefore, it's usage as an alternative resource in interventions that seek tissue regeneration can be considered. Objective: the aim of the present study was to carry out an integrative review of the literature on the use of dentin as a biomaterial for bone regeneration. Methodology: a search for articles was carried out in the Medline databases, via PubMed; Scielo, LILACS, BASE, Scopus and Science Direct, which evaluated or described the use of dentin as a biomaterial for bone regeneration. The following descriptors were used: "Dentin" AND "Bone Regeneration", without time limits. The inclusion criteria were: clinical studies published in journals, derived from primary data, on the use of dentin as a biomaterial. Exclusion criteria were: literature reviews, in vitro and in animal studies, studies that were not possible to be accessed in full and studies that associated the usage of dentin with other biomaterials and that it was not possible to relate the results just by using the dentin. Results: twenty-three studies were selected for the present review. Researches have shown that there is heterogeneity related to the size of the obtained dentin particle, which may be due to different processing methods. Conclusion: the reuse of dentin as a biomaterial can be a promising alternative to autogenous graft. It is suggested, then, that dentin particle processing protocols should are better established and longitudinal studies need to be carried out to the in order to ensure safe, effective and practical procedures.

ABSTRACT

O transplante dentário autógeno é um procedimento cirúrgico que consiste na transposição de um elemento dentário do seu alvéolo para um outro, em um mesmo indivíduo. Esta abordagem é indicada para substituir elementos com prognóstico desfavorável ou reabilitar áreas edêntulas. O objetivo deste trabalho é apresentar as vantagens do transplante dentário autógeno frente a perdas dentárias precoces e os critérios necessários para indicação do mesmo, por meio de um relato de caso clínico no qual, uma paciente do gênero feminino, 16 anos foi submetida ao transplante do elemento 48 para o alvéolo do 47 por motivos de lesão cariosa com extensa destruição coronária com impossibilidade de tratamento clínico restaurador. Em acompanhamento pós-operatório de 01 ano os resultados demostraram continuidade do desenvolvimento radicular do elemento transplantado em seu novo alvéolo, estando este, sem mobilidade, livre de lesões periodontais e/ou endodônticas. Desta forma, conclui-se que as vantagens do transplante dentário autógeno incluem a possibilidade de reabilitação dentária de forma natural, imediata e de baixo custo comparado a tratamentos como implantes e próteses. E este método quando indicado corretamente e realizado sob os devidos cuidados pode alcançar excelentes resultados funcionais e estéticos, sendo uma opção viável para reabilitação de perdas dentárias precoces...

The Autogenous dental transplantation is a surgical procedure that consists of the transposition of a dental element from its socket to another, in the same individual. This approach is indicated to replace elements with an unfavorable prognosis or to rehabilitate edentulous areas. The objective of this paper is to present the advantages of autogenous dental transplantation against early tooth loss and the necessary criteria for its indication, through a clinical case report in which a 16-year-old female patient underwent transplantation element 48 for the alveolus of the 47 due to carious lesions with extensive coronary destruction with impossibility of restorative clinical treatment. In a 01-year postoperative follow-up, the results showed continuity of root development of the transplanted element in its new alveolus, which is without mobility, free from periodontal and/or endodontic lesions. Thus, it is concluded that the advantages of autogenous dental transplantation include the possibility of natural, immediate and low-cost dental rehabilitation compared to treatments such as implants and prostheses. And this method, when correctly indicated and performed with due care, can achieve excellent functional and esthetic results, being a viable option for the rehabilitation of early tooth loss...

ABSTRACT

Durante los últimos años, la cirugía endoscópica transesfenoidal se ha convertido en el procedimiento quirúrgico de elección para el tratamiento de tumores hipofisarios. La técnica de abordaje actual es el resultado de una evolución histórica de vía por craneotomía a vía endonasal con ingreso a través del seno esfenoidal. Aunque la cirugía de tumores hipofisarios vía transesfenoidal endoscópica ha permitido disminuir las complicaciones graves asociadas a los abordajes externos, no está exenta de complicaciones, como la fístula de líquido cefalorraquídeo. A nivel del abordaje nasal, hay escasas descripciones de complicaciones y el compromiso del cartílago septal con deformidad en silla de montar no es una complicación documentada. Se presenta un caso de rinodeformidad en silla de montar poscirugía transesfenoidal de hipófisis en una paciente de 32 años a quien se le practicó una reconstrucción nasal con cartílago costal autólogo. En nuestra búsqueda bibliográfica es el primer caso registrado en Iberolatinoamérica


In recent years, transsphenoidal endoscopic surgery has become the surgical procedure of choice for the treatment of pituitary tumors. The current approach technique is the result of an historical evolution from craniotomy surgery to an endonasal procedure with entry through the sphenoid sinus. Although endoscopic transsphenoidal surgery has made it possible to reduce serious complications associated with external approaches, it is not without complications, such as cerebrospinal fluid fistula. At the level of the nasal approach, there are few descriptions of complications and involvement of the septal cartilage with saddle deformity is not a documented complication. We present a case of saddle rhinodeformity after transsphenoidal pituitary surgery in a 32-year-old patient who underwent nasal reconstruction with autologous costal cartilage. In our bibliographic search, it is the first case registered in IberoLatin America.
