ABSTRACT

Introdução: A taxa de mortalidade em pacientes queimados diminuiu significativamente, tornando importante avaliar outros desfechos, como o tempo de internação, que aumenta a morbidade física e psicológica, o risco de infecção hospitalar e os custos financeiros. O objetivo deste estudo é analisar a relevância de vários fatores no tempo de internação na Unidade de Queimados. Método: Foram incluídos neste estudo 711 pacientes admitidos entre 2011 e 2020 na Unidade de Queimados do Hospital de São José, Centro Hospitalar Lisboa Central, Lisboa, Portugal. Os dados coletados foram analisados utilizando o PSPP para Windows. Resultados: Os pacientes eram predominantemente do sexo masculino, com idade média de 54 anos. O tempo médio de permanência hospitalar foi de 29 dias. Os fatores que prolongaram a estadia hospitalar foram relacionados à gravidade da queimadura, ao número de cirurgias e ao tempo decorrido até a primeira cirurgia, valores laboratoriais alterados tanto no perfil hematológico quanto químico durante a hospitalização, e a presença e o número de infecções documentadas. Conclusão: Existem fatores potencialmente modificáveis que infiuenciam o tempo de permanência hospitalar. Nosso estudo nos permite concluir que o tempo decorrido até a primeira intervenção cirúrgica e a presença e o número de infecções documentadas prolongam significativamente esse desfecho, e ênfase deve ser dada à implementação de medidas que favoreçam a intervenção cirúrgica precoce e o controle rigoroso de infecções.


Introduction: Burn patients' mortality rate has decreased significantly, making it important to evaluate other outcomes, such as length-of-stay, which increases physical and psychological morbidity, risk of nosocomial infection, and financial costs. The objective of this study is to analyze the relevance of several factors in the Burn Unit length-of-stay. Material and Methods: 711 patients were included in this study, admitted between 2011 and 2020 to the Burn Unit at São José Hospital, Centro Hospitalar Lisboa Central, Lisbon, Portugal. Collected data was analyzed using PSPP for Windows. Results: Patients included in the study were predominantly males, with a mean age of 54 years. The mean length of stay was 29 days. The factors that prolonged in-hospital stay were those related to the severity of the burn, the number of surgeries and the time elapsed until the first one, altered laboratory values in both hematologic and chemistry profile during the hospitalization, and the presence and number of documented infections. Conclusion: There are potentially modifiable factors that influence length-of-stay. Our study allows us to conclude that the time elapsed until the first surgical intervention and the presence and number of documented infections significantly prolong this outcome, and emphasis should be given to the implementation of measures that favor early surgical intervention and strict infection control.

ABSTRACT

ABSTRACT Purpose The clinical outcomes of kidney transplantation from deceased donors have seen significant improvements with the use of machine perfusion (MP), now a standard practice in transplant centers. However, the use of perfusate biomarkers for assessing organ quality remains a subject of debate. Despite this, some centers incorporate them into their decision-making process for donor kidney acceptance. Recent studies have indicated that lactate dehydrogenase (LDH), glutathione S-transferase, interleukin-18, and neutrophil gelatinase-associated lipocalin (NGAL) could predict post-transplant outcomes. Materials and Methods Between August 2016 and June 2017, 31 deceased-donor after brain death were included and stroke was the main cause of death. Pediatric patients, hypersensitized recipients were excluded. 43 kidneys were subjected to machine perfusion. Perfusate samples were collected just before the transplantation and stored at -80ºC. Kidney transplant recipients have an average age of 52 years, 34,9% female, with a BMI 24,6±3,7. We employed receiver operating characteristic analysis to investigate associations between these perfusate biomarkers and two key clinical outcomes: delayed graft function and primary non-function. Results The incidence of delayed graft function was 23.3% and primary non-function was 14%. A strong association was found between NGAL concentration and DGF (AUC=0.766, 95% CI, P=0.012), and between LDH concentration and PNF (AUC=0.84, 95% CI, P=0.027). Other perfusate biomarkers did not show significant correlations with these clinical outcomes. Conclusion The concentrations of NGAL and LDH during machine perfusion could assist transplant physicians in improving the allocation of donated organs and making challenging decisions regarding organ discarding. Further, larger-scale studies are required.

ABSTRACT

Background: Following penetrating keratoplasty, cataract surgery warrants certain modifications to ensure maximum survival of the graft. Purpose: To emphasize the intraoperative challenges and surgical manipulations to be followed. Synopsis: The surgeon makes a superior sclerocorneal tunnel avoiding the graft host junction. Dispersive viscoelastic is used. Continuous curvilinear capsulorhexis is done. Cataractous lens aspirated with a low flow rate. The intraocular lens is placed in the bag. Superior peripheral iridectomy and primary posterior capsulorhexis are done. The wound closed with two interrupted 10�nylon sutures. Graft host junction integrity is maintained. Highlights: Ensure 1. Good intraoperative corneal visibility, 2. Avoid graft host junction for main port incision 3. Generous dispersive viscoelastic use/soft shell technique to protect the corneal endothelium, 4. Avoid phaco energy in case of soft cataracts/low phaco energy and flow rates, 5. Phaco probe to be meticulously oriented away from corneal endothelium, 6. Primary posterior capsulorhexis to be done as in any pediatric cataract surgery, 7. Make sure of the graft host junction integrity at the end of the surgery, 8. Restrict to a single port whenever possible.

ABSTRACT

Introducción: El aumento de glúteos tiene como objetivo lograr una apariencia y contorno más joven; así como crear la proporción ideal entre cintura y cadera. Esto se puede lograr mediante la lipoinyección, aunque en este caso existen controversias en cuanto a la viabilidad del tejido injertado y la supervivencia de la grasa. Objetivo: Determinar el porcentaje de supervivencia del injerto de grasa autóloga y su relación con el volumen inyectado en pacientes sometidas a lipotransferencia glútea. Métodos: Se realizó un estudio observacional, descriptivo, de corte longitudinal y prospectivo con una muestra de 44 pacientes sometidas a lipotransferencia glútea en el Servicio de Cirugía Plástica del Hospital Docente Clínico Quirúrgico Dr. Miguel Enríquez en el período comprendido entre marzo de 2018 y junio de 2021. Resultados: El estudio evidencia que, mediante ultrasonido y fórmulas, el volumen promedio y la altura de la de grasa en los glúteos se duplica en el posoperatorio mediato y disminuye en el posoperatorio tardío sin llegar a los valores del preoperatorio. Además, se estableció que cerca de la media del volumen de grasa autóloga injertada en los glúteos sobrevive de manera definitiva en el posoperatorio tardío. Además, quedó establecido que la relación entre el volumen infiltrado y la supervivencia del injerto de grasa autóloga es inversamente proporcional: mientras mayor es el volumen, menor es su supervivencia. Conclusiones: Solo la mitad del volumen de grasa autóloga injertada en los glúteos sobrevive de manera definitiva, y la supervivencia de la grasa es inversamente proporcional al volumen infiltrado(AU)


Introduction: Buttock augmentation aims to achieve a more youthful appearance and contour; as well as creating the ideal proportion between waist and hips. This can be achieved by lipoinjection, although in this case there are controversies regarding the viability of the injected tissue and the survival of the fat. Objective: To determine the percentage of autologous fat graft survival and its relationship with the injected volume in patients undergoing gluteal fat transfer. Methods: An observational, descriptive, longitudinal and prospective study was carried out, with a sample of 44 patients undergoing gluteal lipotransfer, in the plastic surgery service of the Dr. Miguel Enriquez Clinical Surgical Teaching Hospital, in the intermediate period between March 2018 to June 2021. Results: The study shows that through ultrasound and formulas, the average volume and height of fat in the buttocks doubles in the immediate postoperative period, decreasing in the late postoperative period, without reaching preoperative values. Furthermore, it's established that about the mean volume of autologous fat grafted to the buttocks survives definitively in the late postoperative period. In addition, it was established that the relationship between the infiltrated volume and the survival of the autologous fat graft is inversely proportional, the greater the volume, the less its survival. Conclusions: Only half of the volume of autologous fat injected into the buttocks survives definitively, and the survival of the fat is inversely proportional to the volume injected(AU)

ABSTRACT

Objective:To investigate the graft survival rate after total parathyroidectomy (TPTX) plus forearm muscle auto-transplantation in patients with secondary hyperparathyroidism (SHPT) and evaluate the effect of graft survival status on calcium and phosphorus metabolism.Methods:It was a retrospective cohort study. The end-stage renal disease patients who were diagnosed with SHPT and underwent TPTX plus forearm muscle auto-transplantation from November 2015 to December 2018 at the First Affiliated Hospital of Zhejiang University School of Medicine were enrolled. The clinical data including serum calcium, phosphorus, intact parathyroid hormone and alkaline phosphatase preoperative and postoperative 1 week, 1 month and 6 months, and cumulative requirements of calcium carbonate and calcitriol in postoperative 1 month and 6 months were collected. The graft survival rate was summarized and the differences of serum calcium, phosphorus, and supplementation dosage of calcium and calcitriol after surgery between the graft survival group and the graft non-survival group were compared.Results:A total of 191 patients were included in the study, with 95 males (49.7%), and 172 patients of age <60 years old. There were 154 grafts surviving with a graft survival rate of 80.6%. There were no significant differences in the levels of serum calcium, phosphorus, alkaline phosphatase at 1 week, 1 month and 6 months after surgery, and cumulative dosage of calcium carbonate at 1 month and 6 months after surgery between the two groups (all P>0.05). The dose of calcitriol in the graft non-survival group was significantly higher than that in the graft survival group within 1 month after surgery [41.50 (30.00, 45.00) μg vs. 32.75 (25.50, 40.50) μg, Z=-2.307, P=0.021]. However, there was no significant difference in cumulative calcitriol supplementation between the two groups within 6 months after surgery ( P>0.05). Conclusions:The graft survival rate after TPTX plus forearm muscle auto-transplantation is high in SHPT patients. Within 6 months after surgery, there is no significant difference in serum calcium, phosphorus and cumulative supplemental doses of calcium and calcitriol between the graft survival and non-survival groups.

ABSTRACT

ABSTRACT Purpose: To evaluate the clinical course and management of infectious interface keratitis after Descemet membrane endothelial keratoplasty. Methods: A total of 352 cases that had undergone Descemet membrane endothelial keratoplasty were retrospectively reviewed. Patients with infectious interface keratitis during follow-up were analyzed. The microbiological analyses, time to infection onset, clinical findings, follow-up duration, treatment, and post-treatment corrected distance visual acuity were recorded. Results: IIK was detected in eight eyes of eight cases. Three fungal and three bacterial pathogens were identified in all cases. All patients received medical treatment according to culture sensitivity. Antifungal treatment was initiated in two cases with no growth on culture, with a preliminary diagnosis of fungal interface keratitis. Intrastromal antifungal injections were performed in all patients with fungal infections. The median time to infection onset was 164 days (range: 2-282 days). The postoperative infectious interface keratitis developed in the early period in two cases. The mean follow-up duration was 13.4 ± 6.2 months (range: 6-26 months). Re-Descemet membrane endothelial keratoplasty was performed in two patients (25%) and therapeutic penetrating keratoplasty in four patients (50%) who did not recover with medical treatment. The final corrected distance visual acuity was 20/40 or better in five patients (62.5%). Conclusion: The diagnosis and treatment of infectious interface keratitis following Descemet membrane endothelial keratoplasty are challenging. Early surgical intervention should be preferred in the absence of response to medical treatment. Better graft survival and visual acuity can be achieved with therapeutic penetrating keratoplasty and re-Descemet membrane endothelial keratoplasty in patients with infectious interface keratitis.


RESUMO Objetivo: Avaliar o curso clínico e o manejo da ceratite infecciosa de interface após ceratoplastia endotelial da membrana de Descemet. Métodos: Um total de 352 casos submetidos a ceratoplastia endotelial da membrana de Descemet foram revisados retrospectivamente. Pacientes com ceratite infecciosa de interface foram analisados durante o acompanhamento. As análises microbiológicas, o tempo até o início da infecção, os achados clínicos, a duração do acompanhamento, o tratamento e a acuidade visual para longe corrigida pós-tratamento foram registrados. Resultados: Ceratite infecciosa de interface foi detectada em 8 olhos de 8 casos. Três patógenos fúngicos e três bacterianos foram identificados em todos os casos e receberam tratamento médico de acordo com a sensibilidade da cultura. O tratamento antifúngico foi iniciado em dois casos sem crescimento em cultura, com diagnóstico preliminar de ceratite infecciosa fúngica. Injeções antifúngicas intraestromais foram usadas em todos os casos com infecções fúngicas. O tempo médio para o início da infecção foi de 164 dias (variação: 2-282 dias). A ceratite infecciosa de interface pós-operatória desenvolveu-se no período inicial em dois casos. A duração média do acompanhamento foi de 13,4 ± 6,2 meses (variação: 6-26 meses). A ceratoplastia endotelial de membrana de Descemet foi realizada em dois casos (25%) e ceratoplastia penetrante terapêutica em quatro casos (50%) que não se recuperaram com tratamento médico. A acuidade visual para longe corrigida final foi de 20/40 ou melhor em 5/8 (62,5%) dos pacientes. Conclusões: O diagnóstico e o tratamento da ceratite infecciosa de interface após ceratoplastia endotelial da membrana de Descemet são difíceis. A intervenção cirúrgica precoce deve ser o procedimento preferido se não houver resposta ao tratamento médico. Melhor sobrevida do enxerto e melhor acuidade visual podem ser alcançadas com ceratoplastia penetrante terapêutica e ceratoplastia endotelial da membrana de Descemet em pacientes com ceratite infecciosa de interface

ABSTRACT

Antecedente: el trasplante renal es el tratamiento de elección en la enfermedad crónica terminal. Un adecuado seguimiento en el postrasplante mejora la supervivencia del injerto y del paciente a largo plazo. Objetivo: comparar los desenlaces clínicos de la población trasplantada renal que vive en el área metropolitana de Medellín con los que residen por fuera de este lugar, con el fin de plantear un modelo de atención para el seguimiento por medio de la telemedicina. Métodos: estudio descriptivo, retrospectivo y de un único centro. Se determinó la tasa de supervivencia mediante las curvas de Kaplan-Meier. Resultados: durante el período 2005-2015 se realizaron 754 trasplantes, el 42 % vivía por fuera del área metropolitana. Al agrupar esta cohorte según el lugar de residencia, se observó que la supervivencia de los pacientes residentes en el área metropolitana a 1, 3 y 5 años fue del 96,8 %, 93,7 % y 91,8 %, respectivamente, en contraste con el 94,4 %, 90,3 % y 85,2 % de los del área rural. Esta diferencia fue estadísticamente significativa a favor de los que viven en Medellín (log-rank test p = 0,048; Hazard ratio = 1,68; IC 95 % 0,99-2,84, p = 0,052). Conclusión: la supervivencia fue inferior en los pacientes trasplantados renales que viven por fuera del área Metropolitana. Lo anterior motiva el desarrollo de un modelo de atención para estos pacientes mediado por la telemedicina para facilitar el acceso al seguimiento postrasplante.


Background: Kidney transplantation is the treatment of choice for end-stage renal disease. An adequate post-transplant follow-up improves the graft and patient's long-term survival. Objective: The aim of this study was to compare the outcomes of kidney transplant patients who live in the Medellin metropolitan area with those who live outside this area, to propose a model for follow-up care through telemedicine. Methods: Descriptive, retrospective and one-center study. Kaplan-Meier method was used to determine the survival rate. Results: Between 2005 and 2015, 742 patients were transplanted, 42% of whom lived outside the metropolitan area. The survival rates after 1, 3 and 5 years of treatment in patients in the metropolitan area of Medellín compared to those outside were 96.8%, 93.7% y 91.8% and 94.4%, 90.3% y 85.2% respectively, with statistically significant differences (Log-rank test p=0.048, Hazard ratio 1.68, IC 95% 0.99-2.84, p=0.052). Conclusion: The survival rate was lower in kidney transplant patients living outside the urban area. These findings motivate the development of a telemedicine project to facilitate the follow-up of these patients after a kidney transplantation.

ABSTRACT

Resumen Introducción: Los tratamientos inmunosupresores han mejorado las tasas de supervivencia del injerto y del paciente, pero pueden incrementar las infecciones postrasplante. Objetivos: Analizar los datos de pacientes con trasplante renal y describir las bacterias responsables de las infecciones que presentan. Métodos: Estudio observacional, longitudinal y analítico de 103 pacientes sometidos a trasplante renal. El periodo de seguimiento fue de 5.07 ± 1.28 años. Resultados: La tasa de mortalidad fue de 10.68 % y la de pérdida del injerto de 14.56 %. Respecto al riesgo de muerte del receptor, el modelo de regresión de Cox mostró un cociente de riesgo (HR, hazard ratio) de 5.66 en los pacientes con cultivo bacteriano positivo y de 2.22 en aquellos con cepas productoras de betalactamasas de espectro extendido (BLEE); en cuanto a la pérdida del injerto, el HR fue de 4.59 en quienes tuvieron cultivo bacteriano positivo y de 4.25 en aquellos con cepas productoras de BLEE. Conclusiones: Se encontró riesgo significativo de muerte en receptores de trasplante renal con cultivo bacteriano positivo y mayor riesgo de pérdida del injerto en aquellos con cultivo bacteriano positivo y aislamiento de cepas productoras de BLEE. La tasa de enterobacterias productoras de BLEE es alta, por ello son necesarias estrategias más estrictas para controlar del uso de antibióticos.


Abstract Introduction: Immunosuppressive treatments have improved graft and patient survival rates, but can increase the incidence of post-transplant infections. Objectives: To analyze data from kidney transplant patients and describe the pathogens responsible for the infections they experience. Methods: Longitudinal, analytical, observational study of 103 patients who underwent kidney transplantation. The follow-up period was 5.07 ± 1.28 years. Results: Overall mortality rate was 10.68% and graft loss rate was 14.56%. Regarding recipient risk of death, the Cox regression model showed a hazard ratio (HR) of 5.66 for positive bacterial cultures and 2.22 for positive extended-spectrum beta-lactamase (ESBL)-producing strains; as for graft loss, HR was 4.59 in those with positive bacterial cultures and 4.25 in those who were positive for ESBL-producing strains Conclusions: Significant death risk was found in kidney transplant recipients with positive bacterial cultures and an increased risk of graft loss in those with positive bacterial cultures and in those who were positive for ESBL-producing Enterobacteriaceae isolates. The rate of ESBL-producing Enterobacteriaceae is high, and stricter strategies are therefore necessary to control the use of antibiotics.

ABSTRACT

Introdução: A evolução da técnica de lipoaspiração e da enxertia de gordura associada a segurança oncológica permitiram utilizar a gordura como preenchedor autólogo em pacientes com neoplasia de mama que eram submetidas a reconstrução mamária. O objetivo é apresentar uma inovação no instrumento de coleta de gordura que será utilizada como enxerto, para uso em reconstrução mamária. Métodos: Foi realizada a busca de anterioridade nos bancos de dados internacionais e nacional e a confecção de um protótipo de cânula de coleta de gordura de 35cm de comprimento, com diâmetro do tubo de 4mm, com 10 furos redondos na sua extremidade distal com 2mm de diâmetro. Foi realizado um experimento de aspiração de substância viscosa comparando o protótipo com dois modelos de cânulas com desenho padrão da indústria, de três furos tipo Mercedes e de cinco furos tipo Pitanguy. Resultados: Foram encontrados quatro patentes de alta relevância e uma patente de média relevância, que diferem do modelo de utilidade proposto quando se comparam o tipo de desenho da extremidade distal das cânulas estudadas e a função dos instrumentos identificados. Quando comparou-se a eficiência do protótipo, a cânula de cinco furos foi a mais eficiente na aspiração da substância viscosa, e não houve diferença estatística na velocidade de aspiração entre o protótipo e a cânula de três furos tipo Mercedes. Conclusão: A inovação apresentada para a coleta de enxerto de gordura para uso em reconstrução mamária apresentou a mesma eficiência que a cânula Mercedes de três furos neste modelo experimental.


Introduction: The evolution of liposuction and fat graft technique with the oncologic safety allowed to use the fat as autologous filler in patients with breast cancer and submitted to breast reconstruction. The objective is to introduce an innovation in the instrument used to harvest fat grafts for breast reconstruction. Methods: Search of anteriority and trademarks were performed at international and national databases, and a prototype was built as a fat harvest instrument with 35cm in length, 4cm in diameter, with 10 holes at the distal extremity, with 2mm diameter each. It was experimented with a harvest of a viscous substance, comparing the prototype with two regular industry cannulas types: three holes Mercedes' type and five roles Pitanguy's type. Results: Four high-relevance patents and one medium-relevance patent were found, which differ from the proposed utility model when comparing the type of design of the distal end of the studied cannulas and the function of the instruments identified. When the prototype's efficiency was compared with the other cannulas, the cannula with five holes in Pitanguy's type was the most efficient, and it was no statistical difference between the prototype and the cannula with three roles in Mercedes' type. Conclusion: The innovation presented to harvest fat graft for breast reconstruction had the same efficiency in harvesting the viscose substance as the cannula Mercedes type with three holes in this experimental model.

ABSTRACT

Purpose: To evaluate the outcomes of trabeculectomy, graft survival, and risk factors for failure in post penetrating keratoplasty (PK) and Descemet’s stripping endothelial keratoplasty (DSEK) eyes. Methods: We reviewed charts of eyes that underwent trabeculectomy for post keratoplasty glaucoma PK [25 eyes] and DSEK [14 eyes] between 1993 and 2019. The demographics, clinical features, and surgical outcomes were evaluated. Success of trabeculectomy was defined as complete when the intraocular pressure (IOP) was >5 and ?21 mmHg without antiglaucoma medications (AGM) and qualified with AGM. Clear and compact graft was considered for graft success. Results: Median (interquartile range [IQR] preoperative IOP in post?PK eyes and post?DSEK eyes was comparable, 32 (28–38) vs. 31.5 (25–36) mmHg, P = 0.38). Median number of preoperative AGMs was comparable (P = 0.78). Median postoperative follow?up was longer in post?PK, compared with post?DSEK, 2.5 (1.3–3.3) vs. 1 (0.3–2.9) years (P = 0.05). Kaplan–Meier survival estimates for complete and qualified success of trabeculectomy at 3 years were 23.7% and 73.3%, respectively, for PK and 45.8% and 71.6%, respectively, for DSEK. Kaplan–Meier survival estimates for graft survival were 91.8% up to 3 years for PK and 100% until 2 years and 77.8% at 3 years for DSEK. Higher IOP prior to trabeculectomy was a risk factor for failure of trabeculectomy (P = 0.03) and older age was a risk factor for graft failure (P = 0.05) in PK eyes. Number of prior corneal surgeries (P = 0.05) was associated with failure of trabeculectomy and graft failure in post?DSEK eyes. Conclusion: Trabeculectomy had moderate qualified success in post?PK and DSEK eyes at 3 years. Higher pretrabeculectomy IOP and higher number of prior corneal surgeries were significantly associated with failure of trabeculectomy in PK and DSEK eyes, respectively

ABSTRACT

RESUMEN Introducción: El trasplante renal es uno de los métodos de sustitución de la función renal y tiene como factor de mayor influencia en su supervivencia, la compatibilidad inmunológica. Objetivo: Definir la supervivencia del trasplante y su relación con el grado de compatibilidad. Material y Métodos: Estudio retrospectivo, del tiempo de supervivencia con base hospitalaria, de los 827 pacientes trasplantados entre los nueve centros del país, en el quinquenio 2015-2019. Para estimar las curvas de supervivencias se empleó el Método de Kaplan Meier, por el SPSS 22.0. Resultados: Supervivencia del injerto al año 72,9 % y paciente 89,0 %, con media de sobrevida de los injertos de 3,6 años y del paciente de 4,6. Para los pacientes con dos y más compatibilidad, la supervivencia del injerto al año fue mayor, 77,0 % v/s 69,2 % y menos, para el resto. Posterior al año, también son diferentes las supervivencias por grado de compatibilidad. El rechazo agudo inmunológico, que es una de las principales causas de pérdidas de injertos, tiene mucho mayor incidencia en los trasplantados sin compatibilidad que en los compatibles (17,4 % v/s 9,9 %). Para las causas de muerte de los pacientes, la infección fue la predominante, y muy significativo para los que no comparten compatibilidad v/s los que sí (56,9 % v/s 31,9 %). Conclusiones: La compatibilidad inmunológica entre donante y receptor, propicia diferencia en las supervivencias de injertos y pacientes, siendo mejor mientras más compatibles sean el donante y el receptor.


ABSTRACT Introduction: Kidney transplant is one of the methods of kidney function replacement, and immunological compatibility is the most important factor influencing survival. Objective: To define transplant survival and its relationship with the degree of compatibility. Material and Methods: Hospital-based retrospective study of survival time of the 827 transplanted patients in the nine centers of the country during the five-year period (2015 - 2019). The Kaplan Meier method was used to estimate the survival curves, using SPSS version 22.0. Results: The graft survival was 72,9 % and the patient survival was 89,0 % in the first year; the mean graft survival was 3,6 years, and the patient survival was 4,6 years. For patients with two and more compatibilities, graft survival was significantly higher in the first year (77,0 % versus 69,2 %), but it was lower for the rest. One year after, the survival rates related to the degree of compatibility are also different. Acute immune rejection, which is one of the main causes of graft loss, has a much higher incidence among the transplanted patients without compatibility than in the compatible ones (17,4 % versus 9,9 %). Infection was the predominant cause of death in these patients, which was incredibly significant in those who do not share compatibility as opposed to those who do share it (56,9 % versus 31,9 %). Conclusions: Immunological compatibility between donor and recipient results in differences between graft and patient survival rates, so the more compatibility between the donor and the recipient, the higher the survival rate.

ABSTRACT

A reconstrução com enxertia para defeitos resultantes de exérese de carcinoma espinocelular nos membros inferiores é um grande desafio para o cirurgião dermatológico, tendo em vista que uma pele muito fina para a área receptora, a não homogeneidade da vascularização local e a insuficiência venosa transitória dificultam a integração da pele enxertada nessas regiões. Para o sucesso desse tipo de procedimento, podem ser usadas algumas técnicas para reparar essas dificuldades, como um curativo compressivo elástico que utilizamos nos primeiros dias de pós-operatório de enxerto de pele total no pé e na perna, com bons resultados


Reconstruction with grafting for defects resulting from the removal of squamous cell carcinoma in the lower limbs is a great challenge for the dermatological surgeon. A very thin skin for the receiving area, the inhomogeneity of the local vascularization and the transient venous insufficiency make it difficult to integration of the grafted skin in these regions. For the success of this type of procedure, some techniques can be used to repair these difficulties, such as an elastic compressive dressing that we use in the first postoperative days of a total skin graft on the foot and leg, with good results

ABSTRACT

Introducción: el conocimiento de la funcionalidad del injerto y la supervivencia del paciente es fundamental para valorar el éxito del trasplante renal. Objetivo: determinar la supervivencia de los pacientes trasplantados por tipo de donante y la funcionalidad de los injertos renales en una cohorte en México. Material y métodos: cohorte de trasplante renal de 2013 a 2017 en México. Se analizaron 790 pacientes seguidos por un año para valorar la supervivencia de los pacientes trasplantados por tipo de donante y la funcionalidad de los injertos renales. Para ello se usaron medidas de tendencia central y dispersión, así como tablas de supervivencia de Kaplan-Meier con SPSS, versión 25. Resultados: de los 790 pacientes, 518 fueron de donante vivo (65.56%) con supervivencia del paciente de 97.88% y de funcionalidad del injerto de 93.24% a 12 meses de seguimiento; 272 pacientes recibieron el injerto de donante fallecido con supervivencia del paciente de 91.18% y funcionalidad del injerto renal de 84.19%. Conclusiones: aún existe una diferencia de casi 5% en la supervivencia del paciente receptor de un donante vivo en referencia con un donante fallecido. Para la funcionalidad del injerto renal esta diferencia es > 7%. La donación cadavérica ha aumentado; sin embargo, incluso en cifras bajas es de aproximadamente el 35% en México


Background: Knowledge of the functionality of the graft and patient survival is essential to assess the success of kidney transplantation. Objective: To determine the survival of transplanted patients by type of donor and the functionality of kidney grafts in a cohort in Mexico. Material and methods: Kidney transplant cohort from 2013 to 2017 in Mexico. 790 patients followed up for one year were analyzed to assess the survival of transplanted patients by type of donor and the functionality of kidney grafts. For this, measures of central tendency and dispersion were used, as well as Kaplan-Meier survival tables with SPSS, version 25. Results: Out of the 790 patients, 518 were from living donors (65.56%) with patient survival of 97.88% and graft function of 93.24% at 12 months of follow-up; 272 patients received the graft from a deceased donor with patient survival of 91.18% and renal graft function of 84.19%. Conclusions: There is still a difference of almost 5% in the survival of the recipient patient from a living donor compared to a deceased donor. For the functionality of the kidney graft, this difference is > 7%. Cadaveric donation has increased; however, even at low figures is of approximately 35% in Mexico

ABSTRACT

Introducción. El trasplante renal es el tratamiento de elección para la enfermedad renal crónica. Debido a la brecha con la disponibilidad de donantes, el uso de criterios expandidos es una opción que busca mejorar la tasa de donación mundial. El objetivo de este estudio fue comparar la sobrevida del injerto y del paciente trasplantado con donante de criterios expandidos versus el donante estándar. Métodos. Cohorte retrospectiva de 1002 pacientes con trasplante renal donde se determinó la sobrevida del injerto renal y del receptor a 10 años después del trasplante. La sobrevida del injerto renal y el receptor fueron estimadas por el método de Kaplan-Meier. Una regresión de Cox fue realizada ajustando el modelo multivariado.Resultados. El análisis incluyó 1002 receptores, con un 18,8 % (n=189) que correspondían al uso de donante de criterios expandidos. El grupo de trasplante renal con donante de criterios expandidos tuvo menor sobrevida del paciente (48,1 % versus 63,8 %) y del injerto (63,3 % versus 74,7 %) en comparación con el grupo de trasplante renal con donantes con criterios estándar a los 10 años después del trasplante. La asociación de trasplante renal con donante de criterios expandidos y muerte o pérdida del injerto renal no fueron significativas cuando se ajustaron las variables en el modelo multivariado. Conclusión. El trasplante renal con donante de criterios expandidos tiene menor sobrevida del receptor y del injerto frente al grupo de trasplante renal con donante estándar. No hubo diferencias estadísticamente significativas en cuanto al trasplante renal con donante de criterios expandidos frente a la pérdida del injerto renal o muerte.


Introduction. Kidney transplantation is the treatment of choice for chronic kidney disease. Due to the gap with donor availability, the use of expanded criteria is an option that seeks to improve the global donation rate. The objective of this study was to compare the survival of the graft and the transplanted patient with an expanded criteria donor versus the standard donor. Methods. Retrospective cohort of 1002 kidney transplant patients where survival of the kidney graft and the recipient was determined at 10 years after transplantation. The survival of the kidney graft and the recipient were estimated by the Kaplan-Meier method. A Cox regression was performed by fitting the multivariate model. Results. The analysis included 1002 recipients with 18.8% (n=189) corresponding to the use of an expanded criteria donor. The expanded criteria donor kidney transplant group had lower patient (48.1% versus 63.8%) and graft (63.3% versus 74.7%) survival compared to the donor kidney transplant group with standard criteria at 10 years post-transplant. The association of kidney transplantation with expanded criteria donor and death or loss of the kidney graft were not significant when the variables were adjusted in the multivariate model. Conclusion. Kidney transplantation with an expanded criteria donor has a lower recipient and graft survival compared to the standard kidney transplant group. There were no statistically significant differences in expanded criteria donor kidney transplantation versus kidney graft loss or death.

ABSTRACT

Introdução: Perfuração radicular é a comunicação entre as paredes do canal radicular e o espaço periodontal. O tempo, a localização e a dimensão da perfuração são fatores que afetam no prognóstico do dente. Objetivo: Relatar um caso clínico de tratamento de perfuração radicular supraóssea associado a enxertia de tecido conjuntivo em área estética. Relato do caso: Paciente relatou ter sido submetido, há 3 meses, ao tratamento endodôntico do dente #22; porém, esse não foi finalizado. Ao exame clínico, o dente apresentava ausência de dor e presença de fístula na região da gengiva inserida. As imagens radiográficas e tomográficas revelaram imagem sugestiva de perfuração radicular na região vestibular do dente #22, além de área hipodensa/radiolúcida circunscrita ao ápice radicular, conduzindo ao diagnóstico de periodontite apical assintomática associada a perfuração radicular supraóssea. Inicialmente, foi realizado preparo do canal radicular e utilizada medicação intracanal por 21 dias. Posteriormente, foi realizada a obturação do canal radicular e restauração definitiva em resina composta na face palatal. Na mesma sessão, foi realizado o acesso cirúrgico para selamento da perfuração com resina composta, associado a enxertia de tecido conjuntivo no dente #22, para evitar recessão tecidual marginal. Foi observada, após 12 meses, neoformação óssea na região periapical do dente #22, com ausência de dor e preservação da estética na região periodontal. Conclusão: O diagnóstico e o planejamento multidisciplinar são fatores importantes no tratamento de perfurações radiculares, assim como a correta escolha do material selador (AU).


Introduction: Root perforation is the communication between the walls of the root canal and the periodontal space. The time, location and size of the perforation are factors that affect the prognosis of the tooth. Objective: To report a clinical case of treatment of supraosseous root perforation associated with grafting of connective tissue in aesthetic area. Case report: Patient reported that 3 months had started root canal treatment of tooth 22, but was not finalized. At the clinical examination, the tooth presented absence of pain and presence of sinus tract in the region of attached gingiva. Radiographic and tomographic images revealed an image suggestive of root perforation in the buccal region of tooth 22, as well as a hypodense / radiolucent area circumscribed to the root apex, leading to the diagnosis of asymptomatic apical periodontitis associated with supraosseous root perforation. Initially, it were performed root canal preparation and intracanal medication. After 21 days, root canal obturation and composite restoration were performed on the palatal face. In the same session, the surgical access was made to sealing the perforation with composite resin, associated to the grafting of connective tissue in tooth 22, to avoid marginal tissue recession. It was observed after 12 months new bone formation in the periapical region of tooth 22, with absence of pain and preservation of aesthetics in the periodontal region. Conclusion: Multidisciplinary diagnosis and planning are important factors in the treatment of root perforations, as well as the correct selection of materials used to seal root perforations (AU).

ABSTRACT

Resumen Introducción: el trasplante renal es considerado la terapia más efectiva para el tratamiento de la enfermedad renal crónica (ERC). Recientemente, el trasplante renal ha aumentado en los pacientes mayores de 60 años, dado que presenta ventajas relevantes reportadas en la literatura mundial como un menor riesgo de morir, en comparación con pacientes de la misma edad que continúan en diálisis. Objetivo: evaluar la sobrevida del injerto y del paciente adulto mayor en una cohorte de pacientes con trasplante renal. Materiales y métodos: analizamos retrospectivamente una cohorte de 193 pacientes mayores de 60 años, quienes recibieron trasplante renal en el periodo comprendido entre 2008 a 2019 en nuestros centros de trasplante. Se analizaron variables sociodemográficas y clínicas para determinar la sobrevida del injerto y del paciente a 1, 5 y 10 años postrasplante, mediante el método de Kaplan-Meier. Se realizó un modelo de regresión de Cox para evaluar los potenciales factores de riesgo para pérdida del injerto renal en el primer año postrasplante. Resultados: la media de edad de los pacientes fue de 64,62 ± 3,82 años. La sobrevida del injerto censurada por muerte fue del 90 %, 86 % y 75 % en los años 1, 5 y 10 postrasplante, respectivamente, y la sobrevida del injerto no censurada fue del 82 %, 63 % y 43 %, respectivamente y en el mismo orden, en los mismos periodos documentados. Las principales causas de mortalidad fueron infecciones y enfermedad cardiovascular. La sobrevida del paciente adulto mayor fue del 89 %, 70 % y 55 % en los años 1, 5 y 10 postrasplante, respectivamente. Los factores de riesgo asociados a pérdida del injerto renal en el primer año postrasplante fueron: edad mayor a 70 años (HR 4,2; 95 % CI 1,1-15,3), sexo femenino (HR 2,7; 95 % CI 1,01-7,3) y no adherencia al tratamiento (HR 8,1; 95 % CI 2,1-30,7). Conclusión: los pacientes adultos mayores trasplantados tuvieron desenlaces adecuados en el trasplante renal. Es importante definir herramientas de evaluación del paciente adulto mayor que sean objetivas en el pretrasplante, donde la edad no sea una barrera de acceso al trasplante renal para esta población.


Abstract Background: Kidney transplantation is considered the most effective renal replacement therapy for chronic kidney disease. Recently, kidney transplantation is increasing in elderly recipients. Aged patients who have a kidney transplant have relevant advantages compared to dialysis reported in the literature such as better survival. Objective: We aimed to assess graft and patient survival in a cohort of elderly kidney transplant recipients. Materials and Methods: We retrospectively analyzed a cohort of 193 patients older than 60 years who received a kidney transplant from 2008 to 2019 in our transplant centers. Our study included sociodemographic and clinical variables to determine patient and graft survival at 1, 5 and 10 years after kidney transplantation using the Kaplan-Meier method. Cox regression analysis was used to evaluate the potential risk factors for graft loss during the first year of transplantation. Results: The mean recipient age was 64.62 ± 3.82 years old. The 1, 5 and 10-year death-censored graft survival rates were 90%, 86% and 75% and uncensored graft survival probability was 82%, 63% and 43% at 1, 5 and 10 years, respectively. The main mortality causes were infections and cardiovascular disease. Patient survival was 89%, 70% and 55% at 1, 5 and 10 years, respectively. Independent graft loss risk factors in the first year posttransplant were: age >70 (HR 4.2; 95% CI 1.1-15.3), female sex (HR 2.7; 95% CI 1.01-7.3) and non-compliance (HR 8.1; 95% CI 2.1-30.7). Conclusion: We found that older patients experience good outcomes following renal transplantation. There is a need to determine suitable older recipients based on objective selection criteria where age should not be a barrier to the kidney transplant.

ABSTRACT

Abstract Introduction: Multidisciplinary clinics are the best approach towards Chronic Kidney Disease (CKD) patients in pre-dialysis phases. The few studies regarding kidney transplant recipients (KTR) compare multidisciplinary and non-multidisciplinary clinics. Methods: In this study, we compared the quality of multidisciplinary CKD care between 101 KTR and 101 propensity score-matched non-transplant pre-dialysis patients (PDP). Prevalence of patients without specific treatment at any time and percent time without specific treatment for CKD complications were the main outcomes and patient and kidney function survival, glomerular filtration rate (GFR) decline, prevalence of CKD-related complications, and percent time within therapeutic goals were the exploratory ones. Results: Time within most goals was similar between the groups, except for diastolic blood pressure (83.4 vs. 77.3%, RR 0.92, CI 0.88-0.97, p = 0.002) and hypertriglyceridemia (67.7 vs. 58.2%, OR 0.85, CI 0.78-0.93, p < 0.001), better in non-transplant PDP, and for proteinuria (92.7 vs. 83.5%, RR 1.1, CI 1.05-1.16, p < 0.001), better in KTR. Patient survival and GFR decline were similar between the groups, although non-transplant PDP tended to progress earlier to dialysis (9.9% vs. 6.9%, HR 0.39, p = 0.07, CI 0.14-1.08). Discussion: The similar findings between non-transplant PDP and KTR suggests that good and comparable quality of multidisciplinary is a valid strategy for promoting optimal clinical management of CKD-related complications in KTR.


Resumo Introdução: Clínicas multidisciplinares são a melhor abordagem para pacientes com doença renal crônica (DRC) em fases pré-dialíticas. Os poucos estudos sobre receptores de transplante renal (RTR) comparam clínicas multidisciplinares e não multidisciplinares. Métodos: Neste estudo, comparamos a qualidade do atendimento multidisciplinar para DRC entre 101 RTR e 101 pacientes pré-dialíticos (PPD) não transplantados pareados com escore de propensão. A prevalência de pacientes sem tratamento específico em qualquer momento e a porcentagem de tempo sem tratamento específico para complicações de DRC foram nossos desfechos principais, e a sobrevida do paciente e da função renal, declínio da taxa de filtração glomerular (TFG), prevalência de complicações relacionadas à DRC e porcentagem de tempo dentro dos objetivos terapêuticos foram os exploratórios. Resultados: O tempo no alvo para a maioria dos objetivos foi semelhante entre os grupos, exceto para a pressão arterial diastólica (83,4 vs. 77,3%, RR 0,92, IC 0,88-0,97, p = 0,002) e hipertrigliceridemia (67. 7 vs. 58,2%, OR 0,85, IC 0,78-0,93, p < 0,001), melhor em PPD não transplantados, e para proteinúria (92,7 vs. 83,5%, RR 1,1, IC 1,05-1,16, p < 0,001), melhor em RTR. A sobrevida do paciente e o declínio da TFG foram semelhantes entre os grupos, embora PPD não transplantados tendessem a progredir mais cedo para a diálise (9,9% vs. 6,9%, HR 0,39, p = 0,07, IC 0,14-1,08). Discussão: Os resultados semelhantes entre PPD não transplantados e os RTR sugerem que a qualidade multidisciplinar boa e comparável é uma estratégia válida para promover a gestão clínica ideal de complicações relacionadas à DRC em RTR.

ABSTRACT

Background: The impact of donor quality on post-kidney transplant survival may vary by candidate condition. Objective: Analyzing the combined use of the Kidney Donor Profile Index (KDPI) and the estimated post-transplant survival (EPTS) scale and their correlation with the estimated glomerular filtration rate (eGFR) decline in deceased-donor kidney recipients (DDKR). Methods: This was a retrospective, observational cohort study. We included DDKRs between 2015 and 2017 at a national third-level hospital. Results: We analyzed 68 DDKR. The mean age at transplant was 41 ± 14 years, 47 (69%) had sensitization events, 18 (26%) had delayed graft function, and 16 (23%) acute rejection. The graft survival at 12 and 36 months was 98.1% (95% CI 94-100) and 83.7% (95% CI 65-100), respectively. The Pearson correlation coefficient between the percentage reduction in the annual eGFR and the sum of EPTS and KDPI scales was r = 0.61, p < 0.001. The correlation coefficient between the percentage reduction in the annual eGFR and the EPTS and KDPI scales separately was r = 0.55, p < 0.001, and r = 0.53, p < 0.001, respectively. Conclusions: The sum of EPTS and KDPI scales can provide a better donor-recipient relationship and has a moderately positive correlation with the decrease in eGFR in DDKR.

ABSTRACT

Resumen El trasplante renal con donante vivo (DV) ABO incompatible (ABOi) permite aumentar el número de donantes y reducir el tiempo en lista de espera. Los objetivos de este estudio fueron: comparar la supervivencia del injerto, del paciente, los factores de riesgo de rechazo y las complicaciones durante el primer año post-trasplante en los pacientes que recibieron un trasplante DV ABOi entre 2014 y 2019 en nuestra ins titución, emparejados según sexo, edad y riesgo inmunológico con un grupo control de trasplantados DV ABO compatibles (ABOc) en el mismo periodo. Se incluyeron 13 pacientes en cada grupo. No se hallaron diferencias significativas entre los ABOi vs ABOc en la incidencia de retardo de la función del injerto (n = 0 vs. 1), sangrado (0 vs. 0), infecciones (13 vs. 13), rechazo celular (1 vs. 3) y rechazo humoral (4 vs. 3) en el primer año post-trasplante. La tasa de rechazo en los pacientes ABOi no parece tener relación con la incompatibilidad sanguínea, ni se hallaron otros factores de riesgo asociados a rechazo. La supervivencia global de los pacientes fue del 100% en ambos grupos, y la del injerto fue del 92.3% en ABOi y 100% en ABOc (p = 1). El trasplante renal ABOi es una adecuada opción factible en nuestro medio para quienes que no cuentan con donantes compatibles.


Abstract The ABO incompatible (ABOi) living donor (LD) kidney transplant allows increasing the number of donors and reducing the time on the waiting list. The objectives of this study were to compare graft survival, patient survival, rejection risk factors and complications during the first year p ost-transplantation in patients who received an ABOi LD kidney transplant between 2014 and 2019 in our institution, matched according to sex, age and immunological risk with a control group of ABO compatible (ABOc) LD kidney transplants in the same period. Thirteen patients were included in each group. No significant differences were found between ABOi and ABOc in the incidence of delayed graft function (n = 0 vs. 1), bleeding (0 vs. 0), infections (13 vs. 13), cellular rejection (1 vs. 3) and humoral rejection (4 vs. 3) in the first year after transplantation. The rejection rate in ABOi do not seem to be related to blood incompatibility. No risk factors associated with rejection were found. Overall survival of patients was 100% in both groups, and graft survival was 92.3% in ABOi and 100% in ABOc (p = 1). ABOi kidney trans plantation is an adequate feasible option in our environment for those who do not have compatible donors.

ABSTRACT

Tacrolimus (TAC), a calcineurin inhibitor, and everolimus (EVL), an mTOR inhibitor, have been used as immunosuppressive (ISS) drugs in post-kidney transplantation therapy. The objective of this study was to compare the efficacy of EVL vs TAC in the ISS maintenance triple therapy. Ninety-seven kidney transplant patients, who received triple maintenance therapy with TAC, mycophenolate mofetil (MMF), and methyl prednisone (PRED), were evaluated. After four months of post-kidney transplant therapy, 30 patients enrolled in a randomized controlled clinical trial, in which 16 patients received TAC+MMF+PRED (cohort 1), and 14 patients switched to EVL+MMF+PRED (cohort 2). The patients were followed-up for 36 months. Two patients from cohort 1 lost their grafts after one year due to non-adherence. Two patients from cohort 2 had intolerance to mTOR inhibitors and were switched back to TAC from EVL. One case (6.25%) in cohort 1 and three cases (21.43%) in cohort 2 of acute T-cell-mediated rejection was observed. Antibody-mediated acute rejection (ABMAR) was observed in four patients (25.0%) in cohort 1, and antibody-mediated chronic rejection (ABMCR) was observed in two patients (12.50%). One patient from cohort 2 lost the graft after 15 months due to polyomavirus infection. The graft survival rate was 87.50% in cohort 1 and 92.86% in cohort 2. This clinical trial showed that the EVL+MMF+PRED triple maintenance therapy was efficacious compared with TAC during 32 months of follow-up. However, further studies are needed to confirm the efficacy of this regimen for long-term graft survival.
