Complicaciones de pacientes con trasplante renal en las primeras 48 horas en un hospital de tercer nivel de atención / Complications of patients with kidney transplantation in the first 48 hours in a third level hospital

Introducción: el trasplante renal (TR) es la terapia de elección en la mayoría de los pacientes con insuficiencia renal crónica terminal. El conocimiento cada vez más amplio de la inmunología, la mejoría en las técnicas quirúrgicas, el uso de mejores fármacos inmunosupresores y los cuidados en el seguimiento posterior al trasplante han permitido reducir la incidencia de pérdida de injerto y han mejorado la calidad de vida de los pacientes luego del TR. Objetivo: identificar las complicaciones más frecuentes en las primeras 48 horas en pacientes con TR en un hospital de tercer nivel de atención. Métodos: estudio descriptivo y transversal en una muestra aleatoria de 41 pacientes con TR registrados del 5 de enero al 5 de septiembre de 2017 en un hospital de tercer nivel de atención de la ciudad de Veracruz. La información se recabó del expediente clínico como unidad de análisis. Los datos se analizaron con medidas de tendencia central y dispersión. Resultados: el 65.9% fueron hombres; la edad promedio fue de 35 ± 11.3 años. La principal causa de lesión renal crónica fue etiología no determinada (53.7%) e hipoplasia renal (14.6%). El motivo de egreso fue por mejoría en 97.6%. Solo en 10% de los pacientes se presentaron complicaciones, principalmente trombosis segmentada de vena safena interna (30%), trombosis de injerto (3%), trombosis venosa profunda de segmento femoral (2%) y disminución del flujo vascular renal de polo inferior (2%). Conclusión: las complicaciones que se presentaron en los pacientes postrasplantados de riñón en las primeras 48 horas fueron las de tipo vascular.

Introduction: Kidney transplantation is the therapy of choice in the majority of patients with end-stage chronic renal failure. The increasing knowledge of immunology, the improvement in surgical techniques, the use of better immunosuppressive drugs and post-transplant follow-up care have reduced the incidence of graft loss and improved the patients' quality of life after kidney transplantation. Objective: To identify the most frequent complications in the first 48 hours in patients who underwent kidney transplantation in a third level hospital. Methods: Cross-sectional, descriptive study in a random sample of 41 patients with kidney transplantation registered from January 5 to September 5, 2017, in a third level hospital from the city of Veracruz. The information was collected from the clinical record as an analysis unit. Data were analyzed with measures of central tendency and dispersion. Results: 65.9% of patients were male; the average age was 35 ± 11.3 years. The main cause of chronic renal injury was undetermined etiology (53.7%) and renal hypoplasia (14.6%). The reason for discharge was improved health in 97.6% of patients. Only 10% of patients presented complications, mainly internal saphenous vein thrombosis (30%), graft thrombosis (3%), deep venous thrombosis of the femoral segment (2%) and decreased renal vascular flow of the lower pole (2%). Conclusion: The complications that occurred in patients who underwent kidney transplantation in the first 48 hours were vascular.

Clinical evaluation of Toric phakic posterior chamber intraocular collamer lens implantation for ametropia following deep anterior lamellar keratoplasty for keratoconus / 中华实验眼科杂志

Background Postoperative ametropia, especially large astigmatism after deep anterior lamellar keratoplasty (DALK) for keratoconus often results in poor visual acuity.Though postoperative ametropia can be corrected by wearing glasses or performing corneal refractive surgery, the visual quality of patients is still poor, and the operations are difficult to implement because of insufficient corneal thickness.Toric intraocular collamer lens (TICL) implantation appears to have good corrective efficacy on severe astigmatism,but the research on the eyes after DALK is still less.Objective This study was to evaluate the efficacy and safety of TICL implantation for the ametropic eyes following DALK for keratoconus.Methods This study protocol was approved by Ethic Commission of Nanjing Drum Tower Hospital,and written informed consent was obtained from each patient prior to any medical procedure.A self-controlled serial observational research was carried out.Eight ametropic eyes of 8 patients who received the DALK for keratoconus before 18 months were enrolled in Nanjing Drum Tower Hospital from August 201 1 to March 2012, with the spherical diopter range from 0 D to-7.5 D and cylindrical diopter range from-2.5 D to-6.0 D.TICL implantation was performed on the eyes.The eye examinations were carried out before surgery and 1 week,3 months,6 months, 1 year and 2 years after surgery,including uncorrected visual acuity (UCVA) ,best corrected visual acuity (BCVA) ,comprehensive optometry, corneal astigmatism degree, the central corneal thickness and anterior chamber depth (ACD), corneal endothelial cell counts (ECD) ,intraocular pressure.The examination outcomes were compared before and after surgery.The intraoperative and postoperative complications were observed to evaluate the safety of TICL implantation for the ametropic eyes following DALK for keratoconus.Results The UCVA and BCVA were obviously improved at 6 months after TICL implantation in comparison with before surgery and maintained stable during the follow-up duration.The mean spherical diopter was from-0.5 D to-1.0 D and the mean cylindrical diopter was from-0.5 D to-2.0 D after surgery.The corneal endothelial cell counts were (2 520.2 ± 307.2) , (2 496.2 ± 306.2) , (2 469.6±304.5) , (2 432.0 ± 305.4), (2 383.4 ± 309.4)/mm2, and the intraoeular pressures were (14.57 ± 3.75), (16.62±4.21), (16.57±3.56), (15.66±3.37), (15.13±3.48) mmHg, showing insignificant differences among different time points (F =0.375,P =0.825;F =9.871, P =0.394).No significant differences were found in mean ACD and intraocular pressure between before and after surgery (t =1.56 ,P =0.16).The axial deviation of TICL was less than 10° in all the operated eyes 6 months after surgery.No intraoperative and postoperative complications were found during the follow-up duration.Conclusions TICL implantation is a safe and effective alternative and viable approach to myopic and astigmatism patients following DALK for keratoconus.

Cytomegalovirus infection in renal transplantation: clinical aspects, management and the perspectives / Infecção pelo citomegalovírus no transplante de rim: aspectos clínicos, manejo e perspectivas

Cytomegalovirus infection is one of most frequent infectious complications after renal transplantation, and can be classified as primo-infection, when the transmission occurs through the graft, or reactivation, when the recipient is cytomegalovirus seropositive. After transplantation, cytomegalovirus can appear as an infection, when the patient presents with evidence of viral replication without symptoms or disease, which has two clinical spectra: typical viral syndrome or invasive disease, which is a less common form. Their effects can be classified as direct, while the disease is developed, or indirect, with an increase of acute rejection and chronic allograft dysfunction risks. Diagnosis must be made based on viremia by one of the standardized methods: antigenemia or PCR, which is more sensitive. The risk factors related to infection after transplantation are the serologic matching (positive donor and negative recipient) and anti-lymphocyte antibody drugs. One of the strategies to reduce risk of disease should be chosen for patients at high risk: preemptive treatment or universal prophylaxis. Recent clinical research has described ganciclovir resistance as an emergent problem in management of cytomegalovirus infection. Two types of mutation that cause resistance were described: UL97 (most frequent) and UL54. Today, sophisticated methods of immunologic monitoring to detect specific T-cell clones against cytomegalovirus are used in clinical practice to improve the management of high-risk patients after renal transplantation.

A infecção pelo citomegalovírus é uma das principais complicações após o transplante de rim, podendo ser classificada em primoinfecção, quando a transmissão ocorre por meio do enxerto, ou em reativação, quando o receptor é soropositivo. Do ponto de vista clínico, pode se apresentar como infecção, na ausência de sintomas, ou como doença, com dois diferentes espectros: a síndrome viral típica ou, menos comumente, a doença invasiva. Os efeitos podem ser diretos, que é o desenvolvimento da doença, ou indiretos, como aumento no risco de rejeição aguda e de disfunção crônica do enxerto. O diagnóstico deve ser feito por pesquisa de viremia por meio de um dos dois métodos padronizados: antigenemia ou PCR − sendo essa última a mais sensível. Os fatores de risco relacionados com a infecção após o transplante são o match sorológico (doador positivo e receptor negativo) e o uso de anticorpos antilinfócitos. Uma das estratégias de redução de risco de doença deve ser escolhida após o transplante nos pacientes de alto risco: tratamento preemptivo ou profilaxia. Recentemente, linhas de pesquisa clínica têm apontado a resistência ao ganciclovir como um problema emergente no manejo da infecção pelo citomegalovírus. Duas formas de mutação que causam resistência são descritas: UL97, que é a mais frequente, e a UL54. Atualmente, sofisticados métodos de monitorização imunológica, como a detecção de clones específicos de células T contra o citomegalovírus podem ser utilizados na prática clínica para o melhor manejo após o transplante renal dos pacientes de alto risco.

Estudo comparativo das complicações vasculares arteriais e biliares no transplante hepático pediátrico com doador vivo e cadavérico / Comparative study of arterial and biliary complications in pediatric liver transplantation with living and cadaveric donors

Introdução: O transplante de fígado melhorar significativamente a taxa de sobrevivência de crianças e adolescentes com doença hepática terminal. Os pacientes, uma vez que tinha um prognóstico fatal, hoje podem ser submetidos a transplante de fígado (TF), com taxas de sobrevida de aproximadamente 90% em um ano. A atresia biliar é a principal indicação para a população pediátrica e para aqueles sofreram uma portoenterostomia e não obtiveram bons resultados com a mesma, representando mais de 50% das crianças menores de 2 anos na Europa e nos EUA. O transplante representa a única opção restante de sobrevivência com um bom benefício terapêutico. Os avanços nos cuidados cirúrgicos e clínicos, levaram a melhoria das técnicas para aumentar a sobrevida dos pacientes submetidos a transplante de fígado. Porém, a hemorragia e as complicações biliares representam o tendão de Aquiles do desenvolvimento deste processo. Além disso, a escassez de órgãos para a população pediátrica motiva o desenvolvimento de novas modalidades de enxertos de fígado, como a redução do enxerto de fígado, o transplante de fígado dividido, e mais recentemente o de doadores vivos. As complicações arteriais e biliares continuam a ser uma importante causa de morbidade, mortalidade e perda do enxerto após o transplante...

Introduction: Liver transplantation greatly improved the survival rate of children and adolescents with terminal liver diseases. Patients, who once had a fatal prognosis, today can be submitted to liver transplantation (LxT), with survival rates of approximately 90% in one year. The biliary atresia is the main indication in the pediatric population and for those for whom underwent a portoenterostomy and did not obtain good results with it, representing more than 50% of children under the age of 2 years in Europe and the U.S, transplantation represents the only remaining therapeutic option with good survival benefit. Advances in clinical care and surgical techniques led to improved survival of patients undergoing liver transplantation, but still the arterial and biliary complications represent the Achilles tendon in the development of this procedure. Moreover, the shortage of organs for the pediatric population motivate the development of new modalities of liver grafts, such as reduced liver graft, the split-liver transplantation and more recently the living donors. Despite the improved results, vascular arterial and biliary remain an important cause of morbidity, mortality and graft loss after transplantation. Methods: Survey in Pubmed and Lilacs to gather data related complications of pediatric liver transplantation between 1999 to 2009...

Colecistectomia videolaparoscópica em paciente submetido a transplante cardíaco / Laparoscopic cholecystectomy in heart transplant patient

Cardiac transplant has been performed with an increased frequency as the treatment for end-stage cardiac disease. Although cholelithiasis is more frequent in both pretransplant and posttransplant patients, no standard management approach exists. Pretransplant patients are well recognized for cardiac events, and posttransplant immunossupressed patients are at a considerable risk for septic complications. Because the first presentation of gallstones in this population is often acute cholecystitis, asymptomatic calculi cannot be considered benign and it seems reasonable to recommend pretransplant screening and posttransplant surveillance for gallstones. Prophylatic laparoscopic cholecistectomy should be undertaken in the stable patient to avoid the substantial mortality associated with postoperative acute cholecystitis and urgent cholecystectomy. In this case report we present a 44 year-old male with acute cholecystitis after cardiac transplantation who was submitted to a safe laparoscopic cholecystectomy one year and seven months later.
