ABSTRACT

Introducción: El trasplante autólogo de progenitores hematopoyéticos es una terapéutica aplicable en determinadas situaciones a pacientes con Linfoma de Hodgkin. Objetivo: Evaluar la influencia de factores pronósticos seleccionados en los resultados del trasplante autólogo de progenitores hematopoyéticos en pacientes con Linfoma de Hodgkin. Métodos: Se realizó un estudio retrospectivo de 57 pacientes con diagnóstico de Linfoma de Hodgkin trasplantados en el Hospital Clínico Quirúrgico Hermanos Ameijeiras entre 1991 y 2018. La influencia de varios factores desfavorables fue evaluada según sobrevida libre de enfermedad a los cinco años de forma univariada y multivariada. Resultados: Se comprobó una sobrevida libre de enfermedad menor para todos los grupos con las categorías desfavorables. El análisis univariado indicó que el haber recibido tres o más líneas de tratamiento previas, aumentó como promedio 3,48 veces la probabilidad de recaída. En la evaluación múltiple, aumentó de forma significativa la probabilidad de recaída la existencia de enfermedad activa al momento del trasplante (p= 0,023) y el no recibir radioterapia en el tratamiento acondicionante (p= 0,010). Conclusiones: Se demostró la importancia de conocer los factores desfavorables. Notable importancia tuvo evitar enfermedad activa al trasplante y realizar una correcta evaluación de riesgos y beneficios en cuanto a la posible inclusión de la radioterapia en el tratamiento acondicionante(AU)


Introduction: Autologous hematopoietic stem cell transplantation is a therapy used in certain situations to patients with Hodgkin's Lymphoma. Objective: To evaluate the influence of selected prognostic factors on the results of autologous hematopoietic stem cell transplantation in patients with Hodgkin's Lymphoma. Methods: A retrospective study of 57 patients with a diagnosis of Hodgkin Lymphoma transplanted at Hermanos Ameijeiras Clinical Surgical Hospital from 1991 to 2018 was carried out. The influence of several unfavorable factors was evaluated according to univariate and multivariate disease-free survival at five years. Results: A lower disease-free survival was found for all groups with unfavorable categories. Univariate analysis indicated that receiving three or more previous lines of treatment increased the probability of relapse on average 3.48 times. In the multiple evaluation, the probability of relapse was significantly increased by the existence of active disease at the time of transplantation (p = 0.023) and by not receiving radiotherapy in the conditioning treatment (p = 0.010). Conclusions: The importance of knowing the unfavorable factors was established. It was of noteworthy importance to avoid active disease at transplantation and to carry out a correct evaluation of risks and benefits regarding the possible inclusion of radiotherapy in the conditioning treatment(AU)

ABSTRACT

Hip femoral head fractures are extremely uncommon, but likely associated with traumatic hip dislocations. Both lesions require emergent treatment to avoid further complications.19-year-old male patient was received after a high-energy motor vehicle accident with severe brain and thoraco-abdominal trauma and a displaced femoral head fracture with posterior hip dislocation with no acetabular fracture. An emergent open reduction and internal fixation with 2 headless screws was performed, as well as posterior capsule repair. After 1 month as an inpatient in Intensive Care Unit, he sustained a new episode of posterior hip dislocation. Consequently, a second successful surgical reduction was obtained, and hip stability was achieved by posterior reconstruction with iliac crest autograft fixed with cannulated screw and posterior structure repair. Two years later, he was able to walk independently and he does not present any signs of degenerative joint disease nor avascular necrosis.


Las fracturas de la cabeza femoral son extremadamente raras y están asociadas comúnmente con una luxación de cadera traumática. Ambas lesiones requieren tratamiento urgente con el objetivo de evitar complicaciones posteriores. Un paciente varón de 19 años fue trasladado tras un accidente de tráfico de alta energía en el que sufrió un traumatismo craneoencefálico y toracoabdominal grave, además de una fractura de cabeza femoral desplazada junto a una luxación posterior de cadera sin afectación acetabular. De manera urgente, fue intervenido mediante una reducción abierta y fijación interna de la fractura con dos tornillos canulados sin cabeza y reparación de la cápsula articular posterior. Tras un mes de ingreso en la unidad de cuidados intensivos, sufrió un nuevo episodio de luxación posterior de cadera. Debido a ello, se realiza una segunda intervención quirúrgica con reducción abierta y en la que se obtiene una adecuada estabilidad de la cadera mediante reconstrucción posterior con la adición de autoinjerto tricortical de cresta ilíaca y reparación capsular posterior. Después de dos años de seguimiento, el paciente deambula de manera independiente, sin dolor y sin signos degenerativos ni de necrosis avascular en las pruebas de imagen.

ABSTRACT

Se describe el caso clínico de una paciente de 58 años de edad, quien acudió a la consulta de Ortopedia y Traumatología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba porque hacía alrededor de 5 años comenzó a notar aumento progresivo de volumen en el dorso de la mano izquierda, cercano a la articulación metacarpofalángica del tercer dedo, que le dificultaba la extensión y resultaba antiestético. Mediante la ecografía se observó una imagen ecogénica, bien delimitada, que infiltraba el espesor del tendón, por lo que se realizó la exéresis del tumor. Se comprobó la infiltración de dicho tendón, el cual se resecó y se sustituyó con autoinjerto del tendón accesorio que envía el tendón del dedo anular. Los resultados de los estudios histológicos informaron que se trataba de un tumor de células gigantes de la vaina con infiltración tendinosa. Se inmovilizó durante 3 semanas y la recuperación funcional se completó a los 45 días.


The case report of a 58 years patient is described. She went to the Orthopedics and Traumatology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba because she began to notice progressive increase of volume in the back of the left hand around 5 years ago, near the metacarpusphalangic articulation of the third finger that made its extension difficult and was unsightly. By means of the scan, a well defined echogenic image that infiltrated the thickness of the tendon was observed, reason why the exeresis of the tumor was carried out. The infiltration of this tendon was confirmed, which was dried up and substituted with self-graft of the accessory tendon that sends the ring finger tendon. The results of the histologic studies reported that it was a giant cell tumor of the sheath with tendinous infiltration. The hand was immobilized during 3 weeks and the functional recovery was completed at 45 days.

ABSTRACT

OBJECTIVE@#To summarize the clinical and Laboratory characteristics of patients with multiple myeloma (MM) and analyze the prognostic factors.@*METHODS@#Two hundred MM patients were retrospectively analyzed for the following parameters, including peripheral blood, bone marrow morphology, cytogenetics, clinical staging, and response to the chemotherapy in order to summarize related factors affecting overall survival (OS). The prognostic factors were also analyzed.@*RESULTS@#200 patients with MM were divided into 3 groups according to bone marrow plasma cell percentage (BMPC%) in bone marrow smears: <10% group (74 cases, 37.0%), 10%-50% group (75 cases, 37.5%), >50% group (51 cases, 25.5%). Compared with the other two groups, patients in BMPC%<10% group were characterized by lower clinical staging levels, lower rates of 13q14 deletion and t(11;14) positive, better response to chemotherapy and favorable three-year OS rate. The univariate analysis showed that prognostic factors indicating favorable outcome as evaluated by OS included age≤55 years old, BMPC%<10%, WBC<7.5×10@*CONCLUSION@#The clinical characteristics are different among MM patients with different BMPC% in bone marrow smears at initial diagnosis, and prognostic analysis shows that the BMPC% in bone marrow smears has an effect on OS rate. BMPC% in bone marrow smears at initial diagnosis, age, WBC, Hb, response to the fourth chemotherapy are also the main factors impacting the prognosis of patients.

ABSTRACT

OBJECTIVE@#To assess the impact of early relapse (ER) after autologous hematopoietic stem cell transplan-tation (AHSCT) on overall survival (OS) for multiple myeloma (MM) patients.@*METHODS@#Clinical data of 37 patients with MM undergoing AHSCT in department of hematology of Shanxi Bethune Hospital from January 2012 to December 2017 were retrospectively analyzed. The effect of ER on OS of patients was analyzed. The effects of international staging system (ISS) staging, cytogenetics, pre-transplant efficacy, minimal residual disease, and age on OS of the patients were also analyzed respectively.@*RESULTS@#Among the 37 patients, 13 cases (35.1%) had ER, and 24 cases (64.9%) had non-ER. 3 patients with ER had extramedullary disease, but none with non-ER showed extramedullary disease. More than or equal to very good partial rate (VGPR) in patients with ER and without ER were 3 cases (23.1%) and 15 cases (62.5%), respectively, and the curative effect of the former was significantly lower than that of the latter (P<0.05). The median follow-up time was 31 (12-96) months, and median OS time was 93 months in all the patients. The median survival time of patients with ER was 17 months, and the median progression free survival was 7 months, both were significantly shorter than 93 months and 38 months of patients with non-ER (P<0.05). Univariate analysis showed that the OS was affected by ER, cytogenetic abnormalities (FISH), and ≥VGPR before transplantation. Multivariate analysis showed that ER was an independent prognostic factor.@*CONCLUSION@#The prognosis of patients with ER after AHSCT in newly diagnosed MM is poor. ER is an independent prognostic factor of survival.

ABSTRACT

OBJECTIVE@#To investigate the efficacy, safety and prognosis of auto-HSCT between classical and modified conditioning regimen in patients with B-cell non-Hodgkin lymphoma.@*METHODS@#36 patients diagnosed as B-cell non-Hodgkin lymphoma treated with autologous hematopoietic stem cell transplantation from January 2015 to June 2018 in Tianjin Cancer Hospital were retrospectively analyzed. The patients were divided into two groups: Idarubicin group and non-Idarubicin group. The overall survival (OS), progression-free survival (PFS), adverse reactions and hematopoietic reconstitution time between the two groups were compared. Survival analysis was performed by using the Kaplan-Meier method. Log-rank test was used for comparison between groups, and Cox regression was used for multivariate analysis.@*RESULTS@#The median follow-up time was 29 months. Among these 36 patients with B-cell non-Hodgkin lymphoma before transplantation, 21 patients achieved CR and 15 patients achieved PR. The reconstitution time of neutrophil (P>0.05) and platelet (P>0.05) was not significantly different between Idarubicin and non-Idarubicin group. Also, the adverse reactions were not significantly different between two groups. The addition of idarubicin showed not aggravate the adverse reactions of patients. The OS and PFS of patients with idarubicin was longer than that of patients without idarubicin. The multivariate analysis showed that, the modified conditioning regimen and the remission state before transplantation were closely associated with prognosis.@*CONCLUSION@#The above-mentioned results indicated that the combination of modified conditioning regimen with idarubicin can lengthen the OS and PFS of the patients significantly, and show not aggravate of bone marrow inhibition, moreover, the hematopoietic reconsititution time show not lengthen, which means that it can be a safe and effective choice for autologous HSCT in the patients with B cell non-Hodgkin lymphoma.

ABSTRACT

OBJECTIVE@#To investigate the clinical features and prognostic factors of patients with extranodal NK/T cell lymphoma (ENKTL).@*METHODS@#The clinical data of patients with ENKTL from November 2009 to November 2019 was collected and retrospectively analyzed to clarify the clinical features of ENKTL, and evaluate the factors that affected survival and prognosis.@*RESULTS@#Forty-seven patients with ENKTL were collected, median age was 40 (12-82) years old, and more common in males than females, at the ratio of 1.47∶ 1. The median follow-up was 28 (1-112) months, and 5-year overall survival (OS) rate was 49.3%. The 5-year OS rates of the subjects with ECOG performance stage 0-1 and ≥2 were 51.6% and 0 (P=0.001), respectively. The 5-year OS rates of International Prognostic Index (IPI) score 0-1 and ≥2 were 60.0% and 40.6% (P=0.027), respectively. The 5-year OS rates of Ann Arbor staging Ⅰ/Ⅱ and stage Ⅲ/Ⅳ were 61.3% and 31.7% (P=0.005), respectively. The 5-year OS rates of the patients with presentation of B symptoms and without presentation of B symptoms were 79.0% and 30.1% (P=0.013), respectively. The 5-year OS rates of plasma EBV-DNA level < 5×10@*CONCLUSION@#ECOG score, B symptoms, the copy number of EBV-DNA, and treatment regimens are independent prognostic factors for OS of patients with ENKTL.

ABSTRACT

METHODS@#From January 2005 to December 2013, 83 patients with refractory/recurrent CD20@*RESULTS@#All the patient achieved complete response. The median follow.up time was 39 months. Both the two groups collected peripheral blood stem cells successfully, and had no difference in hematopoietic reconstitution time. Three patients in treatment group and six patients in control group relapsed and the three year overall survival and EFS in treatment group was significantly higher than that in control group, that is(93.0% vs 73.1%, P=0.037) and (89.5% vs 65.4%, P=0.034), respectively. Subgroup analysis showed that: compared with the treatment group in which using R in the whole courses(before and after transplantation, and collection of stem cells) was superior to the control group in both OS and EFS, with the OS 97% vs 87.5% (P>0.05) and EFS 97% vs 76.2% (P=0.05) respectively. While stratified by the different courses of rituximab, the OS was 88.9% (1-2 courses, 9 cases), 93.1% (3-4 courses, 29 cases), 94.7%(more than 5 courses,19 cases), and EFS was 77.8%, 89.7% and 94.7%, respectively.@*CONCLUSION@#For the patients with refractory/recurrent CD20

ABSTRACT

BACKGROUND@#The impacts of previous cardio-cerebrovascular disease (pre-CCVD) on the outcomes of hematopoietic cell transplantation (HCT) are not well described. Patients with pre-CCVD may often be poor candidates for HCT. This study aimed to investigate the impact of pre-CCVD on transplant outcomes.@*METHODS@#A retrospective study was conducted between patients with and without pre-CCVD who consecutively received allogeneic or autologous HCT between November 2013 and January 2020 with a matching of age and disease status. The cardiovascular complications and HCT outcomes of the two groups were evaluated and compared. The primary endpoints were post-transplant cardio-cerebrovascular disease (post-CCVD) and non-relapse mortality (NRM). We used a multivariable Cox proportional hazard model and the Fine-Gray competing risk regressions for analyses to estimate the hazard ratios (HRs).@*RESULTS@#The outcomes of 23 HCT recipients with pre-CCVD were compared with those of 107 patients in the control group. No significant differences were noted in terms of engraftment, overall survival (OS) (67.00% vs. 67.90%, P = 0.983), or relapse (29.78% vs. 28.26%, P = 0.561) between the pre-CCVD group and the control group. The cumulative incidences of 2-year NRM were similar between patients with pre-CCVD and the controls (14.68% vs. 17.08%, P = 0.670). However, pre-CCVD was associated with an increased incidence of post-CCVD (HR: 12.50, 95% confidence interval [CI]: 3.88-40.30, P < 0.001), which was an independent risk factor for increased NRM (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001) and inferior OS (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001).@*CONCLUSIONS@#These findings suggest that the existence of pre-CCVD before transplantation might not result in increased mortality directly but superpose the toxicity of the transplantation procedure, leading to a risk of post-CCVD. Post-CCVD was a powerful predictor for high NRM and inferior OS. Further risk stratification of pre-CCVD is needed to reduce NRM in various transplantation settings.

ABSTRACT

RESUMEN: Comparar mediante una revisión sistemática los resultados clínicos de los procedimientos de cirugía plástica periodontal/periimplantar (CP) con injerto de tejido blando autógeno (ITB) obtenido del área lateral del paladar (ALP) versus del área de la tuberosidad (AT). Se realizó una búsqueda electrónica de ensayos clínicos en la base de datos Medline/Pubmed, Cochrane y las revistas de Periodoncia e Implantes de mayor impacto según la Web of Science, para hallar artículos publicados hasta abril del 2020. Se valoró el riesgo de sesgo de los artículos añadidos según el manual Cochrane Versión 5.1.0 para ensayos clínicos aleatorizados y la escala Newcastle-Ottawa para ensayos clínicos controlados. De una muestra inicial de 930 artículos, cuatro ensayos clínicos (tres aleatorizados) fueron incluidos en el presente estudio, donde se realizaron un total de 87 CP alrededor de piezas e implantes dentales, de las cuales 42 cirugías fueron realizadas con ITB del ALP y 45 cirugías con ITB del AT, se evaluó los resultados desde las 8 semanas hasta los 12 meses. No se hallaron diferencias estadísticamente significativas en los resultados clínicos entre ambos grupos, se mejoró el fenotipo gingival en la zona receptora para el grupo que obtuvo el ITB del AT y el nivel del dolor del sitio donador del AT fue menor en las dos primeras semanas que el sitio donante del ALP. Los estudios incluidos manifestaron un bajo riesgo de sesgo en promedio. Ambas áreas donantes de injerto de tejido blando proporcionan resultados clínicos similares, el injerto del área de la tuberosidad mejora el fenotipo gingival de la zona receptora y reduce el dolor post operatorio en las primeras semanas del sitio donador.


ABSTRACT: The objective of the study was to compare, through a systematic review, the clinical results of periodontal / peri-implant plastic surgery (CP) procedures with autogenous soft tissue graft (ITB) obtained from the lateral palate area (ALP) versus the tuberosity area (AT). We conducted an electronic search of clinical trials in the Medline/Pubmed, Cochrane database and the journals of Periodontics and Implants with the greatest impact according to the Web of Science, to find articles published until April 2020. The risk of bias of the articles added was assessed according to the Cochrane Manual Version 5.1.0 for randomized clinical trials and the Newcastle-Ottawa scale for controlled clinical trials. From the initial sample of 930 articles, four clinical trials were included (three randomized) in the present study, where a total of 87 PC were performed around dental pieces and implants, of which 42 surgeries were performed with ITB of the ALP and 45 surgeries with ITB of the AT, the results were evaluated from the 8 weeks to 12 months. No statistically significant differences were found in the clinical results between the two groups, the gingival phenotype in the receiving area was improved for the group that obtained the ITB of the AT and the level of pain at the donor site was lower in the first two weeks than the ALP donor site. The studies showed a lowrisk of bias on average. Both soft tissue graft donor areas provide similar clinical results, grafting the tuberosity area improves the gingival phenotype of the recipient area and reduces post-operative pain of the donor site in the first few weeks.

ABSTRACT

A pele de tilápia possui microbiota não infecciosa e estrutura morfológica semelhante à pele humana. Estudos clínicos fase II, ainda não publicados, mostraram resultados promissores na sua utilização para tratamento de queimaduras. Nos protocolos destes estudos, pacientes com lesões em áreas de dobras de pele, como genitais e região inguinal, foram excluídos, pois achava-se que o biomaterial não aderiria apropriadamente, resultando em um grau de cicatrização inferior. Relato de caso de paciente do sexo feminino, 18 anos, sem comorbidades, com queimaduras de segundo grau profundo em abdômen, região inguinal, parte da genitália e metade superior de ambas as coxas, envolvendo 13,5% da área total da superfície corporal. A pele de tilápia foi aplicada nas lesões levando a uma reepitelização completa com 16 dias de tratamento. Não foram observados efeitos colaterais. A pele de tilápia traz, portanto, a promessa de um produto inovador, de fácil aplicação e alta disponibilidade, que pode se tornar a primeira pele animal nacionalmente estudada e registrada pela Agência Nacional de Vigilância Sanitária, para uso no tratamento de queimaduras. Este relato de caso contribui para reduzir as limitações em relação às áreas anatômicas apropriadas para a aplicação da pele de tilápia, uma vez que, mesmo com a necessidade de reposição de pele, foram obtidos bons resultados com aplicação na genitália e região inguinal.


Tilapia skin has a non-infectious microbiota and a morphological structure similar to human skin. Phase II clinical studies, not yet published, have shown promising results in their use for the treatment of burns. In the protocols of these studies, patients with lesions in areas of skin folds, such as genitals and inguinal regions, were excluded, as it was thought that the biomaterial would not adhere properly, resulting in a lower degree of healing. Case report of a female patient, 18 years old, without comorbidities, with deep second-degree burns in the abdomen, inguinal region, part of the genitalia and upper half of both thighs, involving 13.5% of the total body surface area. Tilapia skin was applied to the lesions leading to a complete re-epithelialization with 16 days of treatment. No side effects were observed. Tilapia skin, therefore, brings the promise of an innovative product, easy to apply, and highly available, which can become the first animal skin nationally studied and registered by the Agência Nacional de Vigilância Sanitária, for use in the treatment of burns. This case report contributes to reduce the limitations concerning the anatomical areas appropriate for the application of tilapia skin, since, even with the need for skin replacement, good results were obtained with application to the genitalia and inguinal region.

ABSTRACT

Introducción: El injerto óseo autólogo tomado de la cresta ilíaca posterior para artrodesis de columna presenta ventajas: es osteogénico, osteoinductor y osteoconductor, y sus desventajas son ofrecer una cantidad limitada y las complicaciones del sitio dador (8-39%), como dolor de la zona dadora, lesión neurovascular y fracturas de pelvis. Los objetivos de este estudio fueron comparar la toma de injerto cortico-esponjoso de cresta ilíaca posterior mediante técnica con escoplo gubia frente a la toma con cureta; evaluar las complicaciones intraoperatorias y posoperatorias; cuantificar la cantidad recolectada y graduar el dolor en la zona dadora. Materiales y Métodos: Estudio prospectivo aleatorizado de 34 pacientes consecutivos para artrodesis posterolateral de columna torácica y lumbosacra (26 mujeres y 8 hombres, de entre 15 y 79 años de edad). Se los dividió en dos grupos: grupo 1, cureta y grupo 2, escoplo gubia. Se evaluaron el peso obtenido, el tiempo requerido y las complicaciones. Resultados: Grupo 1: 19 pacientes (14 mujeres y 5 hombres). Se requirieron, en promedio, 9.94 min para obtener 9,26 g. En el primer control, 13 pacientes presentaron un valor 1; 5, un valor 2 y uno, un valor 3. En el tercer control, 15 tuvieron un puntaje 1; 2, un puntaje 2 y 2, un puntaje 3. Grupo 2: 15 pacientes (12 mujeres y 3 hombres). Se tomaron 11,26 g en 8,6 min. En puntaje de dolor en el primer control fue: 10 pacientes con un valor 1; 2, con un valor 2 y 3, con un valor 3, todos tuvieron un puntaje 1 en el tercer control. Conclusiones: La toma de injerto de cresta ilíaca posterior utilizando escoplo gubia es más rápida, recolecta más injerto y provoca menos dolor a los 60 días. Nivel de Evidencia: II


Introduction: The autologous bone graft harvested from the posterior iliac crest for spinal fusion presents osteogenic, osteoinductive and osteoconductive advantages; however, its disadvantages include a limited amount of available material and an incidence of donor site complications ranging from 8% to 39%, including donor site pain, neurovascular injury and pelvic fractures. Objectives: To compare the posterior iliac crest corticoancellous harvest using a chisel-gouge approach versus a curette approach; to evaluate intra-operative and post-operative complications; to quantify the harvested bone; to grade donor site pain. Materials and Methods: Prospective randomized study in 34 consecutive patients for posterolateral fusion of the thoracic and lumbosacral spine; 26 women and 8 men, between 15 and 79 years of age. Subjects were divided into two groups. Group 1: curette approach; and Group 2: chiselgouge approach. The evaluation included: the amount of bone harvested, the time required and complications. Results: Group 1: 19 patients, 14 women and 5 men. The procedure lasted an average of 9.94 min, and the harvested material averaged 9.26 g. Denis Pain Scale scores at the first follow-up survey: 13 patients scored 1; 5 scored 2; 1 scored 3. Denis Pain Scale scores at the third follow-up survey: 15 patients scored 1; 2 scored 2; 1 scored 3. Group 2: 15 patients, 12 women and 3 men. The procedure lasted an average of 8.6 min, and the harvested material averaged 9.26 g. Denis Pain Scale scores at their first follow-up: 10 patients scored 1; 2 scored 2; 3 scored 3. At the third follow-up, all patients scored 1. Conclusions: We observed that the posterior iliac crest graft harvested using the chisel-gouge approach is faster, provides more graft and results in less pain at 60 days. Level of Evidence: II

ABSTRACT

Chronic septic bone nonunion requires a well-designed therapeutic planning, demanding a multimodal treatment to achieve bone consolidation and elimination of infection. A successful case of an association of the major omentum flap with surgical stabilization with an interlocking nail for treatment of a femoral septic nonunion in dog is reported. The patient had partial functional return of the limb 30 days after surgery, negative bacterial culture with radiographic signs of bone healing and total functional return of the limb at 90th days after the surgical procedure.(AU)


Não uniões ósseas associadas à osteomielite crônica necessitam de um planejamento terapêutico muito bem realizado, demandando tratamento multimodal para conseguir atingir a consolidação óssea e eliminar a infecção.

ABSTRACT

OBJECTIVE@#To evaluate clinical effect of quadriceps tendon autograft and bone-patellar tendon-bone autograft on anterior cruciate ligament reconstruction by Meta-analysis.@*METHODS@#From the time of building databases to May 2019, literatures on case control study on quadriceps tendon and bone-patellar tendon-bone autograft on anterior cruciate ligament reconstruction were searched form PubMed, EMbase, the Cochrane library, Wanfang and CNKI database. Literature screening, quality evaluation and data extraction were carried out according to include and exclude standard. Difference of forward displacement between the affected and health knee, Lachman test, axial shift test, Lysholm score, international knee documentation committee (IKDC) objective grade, anterior knee joint pain and transplant failure rate were analyzed by Meta analysis.@*RESULTS@#Totally 6 literatures were included, including 915 patients with anterior cruciate ligament reconstruction, 495 patients with quadriceps tendon autograft and 420 patients with bone patellar tendon bone autograft. There were no statistical differences in anterior displacement of tibia was less than 3 mm[=1.53, 95%CI(0.68, 3.44), =0.31], 3 to 5 mm [=0.64, 95%CI(0.31, 1.35), =0.24], greater than 5 mm[=1.18, 95%CI(0.33, 4.22), =0.80], negative rate of Lachman test[=0.88, 95%CI(0.38, 2.02), =0.76], negative rate of axial shift test[=0.63, 95%CI(0.24, 1.68), =0.36] between two groups. There were no differences in Lyshlom score[=-0.56, 95%CI(-2.00, 0.89), =0.45], IKDC objective grade A and B[=0.87, 95%CI (0.47, 1.60), =0.66], and transplant failure rate [=0.76, 95%CI (0.28, 2.02), = 0.58]. In reducing anterior knee pain, quadriceps tendon autograft was better than that of bone patellar tendon bone autograft [=0.16, 95%CI (0.09, 0.29), <0.000 01].@*CONCLUSION@#Quadriceps tendon autograft and bone patellar tendon bone autograft on anterior cruciate ligament reconstruction has equal clinical and functional outcomes, transplant failure rate, quadriceps tendon autograft could reduce anterior knee pain.

ABSTRACT

@#Objective. This study aims to determine recurrence and complication rates among patients who underwent three current pterygium treatment techniques: preoperative subpterygeal injection of mitomycin C, intraoperative application of mitomycin with pterygium excision and pterygium excision with conjunctival autograft. Methods. This is a randomized controlled clinical trial in a tertiary hospital. We included patients with diagnosed primary pterygium and who underwent either: A = pre-operative injection of 0.02% mitomycin C one month prior to pterygium excision; B = pterygium excision with intraoperative mitomycin C application; or C = pterygium excision with conjunctival autograft. Results. We included 111 patients: a total of 120 eyes randomized to 3 groups (A, B, C) at 40 eyes per group. After 24 months of follow-up, there was no significant difference in the recurrence rates among the groups (6/40 [15%] in groups A and B and 2/40 cases [5%] in group C; P=0.29). No complications were noted in groups B and C, while 1 case of scleral thinning was noted in group A. There was no significant difference in the complication rates among the three procedures (P=1.00). Conclusion. There were no significant differences in the recurrence and complication rates among the three techniques. Careful patient selection and follow-up are recommended to prevent complications such as scleral thinning.

ABSTRACT

Background The treatment of choice of newly diagnosed multiple myeloma (NDMM) is an induction with proteasome inhibitors followed autologous stem cell transplantation (HSCT). Since 2013, the treatment of these patients in the public system is based on CTD (cyclophosphamide, thalidomide, and dexamethasone). Aim To evaluate the response rates achieved with CTD, and the results of HSCT in patients with NDMM in the public setting. Material and Methods Data from patients considered as candidates for HSCT from different centers of the National Adult Antineoplastic Drug Program (PANDA, for its acronym in Spanish), diagnosed between 2013 and 2017, was analyzed. The response to treatment of first and second lines of treatment was evaluated, in addition to the results of HSCT. An optimal Response was defined as the sum of strict complete remission, complete remission and very good partial response (sCR, CR and VGPR). Results One hundred and seventy-seven patients were analyzed, 54% women, and 53% with IgG multiple myeloma. Information about the international staging system was retrieved in 127 patients (71%). Seventeen percent were ISS I, 22% in ISS II and 32% ISS III. CTD was used as first treatment in 106 patients (60%), and cyclophosphamide, bortezomib and dexamethasone (CyBorD) in 13 (7%). As first line, CTD had an overall response of 50.9%, and CyBorD of 76.9%. Thirty patients were treated with bortezomib as second line treatment. Forty patients (22%) underwent HSCT. The 5-year Overall Survival (OS) in transplanted patients and non-transplanted patients was 100 and 62% respectively (p < 0.01). Conclusions The response rate achieved by CTD in these patients is suboptimal. The response to CyBorD was better.

ABSTRACT

Abstract In cases of aortic valve disease, prosthetic valves have been increasingly used for valve replacement, however, there are inherent problems with prostheses, and their quality in the so-called Third World countries is lower in comparison to new-generation models, which leads to shorter durability. Recently, transcatheter aortic valve replacement has been explored as a less invasive option for patients with high-risk surgical profile. In this scenario, aortic valve neocuspidization (AVNeo) has emerged as another option, which can be applied to a wide spectrum of aortic valve diseases. Despite the promising results, this procedure is not widely spread among cardiac surgeons yet. Spurred on by the last publications, we went on to write an overview of the current practice of state-of-the-art AVNeo and its results.
