Asociación de trasplante de progenitores hematopoyéticos y síndrome de Parsonage-Turner: ¿coincidencia o relación causa-efecto? / Association between hematopoietic stem cell transplantation and Parsonage Turner syndrome: coincidence or cause-effect relationship?

El síndrome de Parsonage-Turner o plexopatía braquial idiopática es una inflamación total o parcial del plexo braquial cuya presentación típica es una omalgia intensa y súbita, seguida de debilidad braquial y amiotrofia precoz. La etiología es desconocida, aunque se propone un mecanismo inmunomediado.El trasplante de progenitores hematopoyéticos es un tratamiento bien establecido de las neoplasias hematológicas y tiene un papel creciente en el tratamiento de enfermedades autoinmunes. Los efectos adversos neurológicos son probablemente infradiagnosticados.La asociación del síndrome de Parsonage-Turner y el trasplante de progenitores hematopoyéticos es muy poco conocida. Describimos dos casos clínicos de plexopatía braquial idiopática tras trasplante de células stem (progenitores) hematopoyéticas (TPH).La reconstitución del sistema inmune tras un trasplante de progenitores hematopoyéticos puede ser un desencadenante de plexopatía braquial, aunque se necesitan más estudios para entender la fisiopatología de esta entidad y establecer su relación causal con el trasplante.

Parsonage-Turner syndrome or idiopathic brachial neuritis is a total or partial inflammation of the brachial plexus, with a typical presentation as a sudden and very intense pain in the shoulder, followed by weakness and early amyotrophy. The etiology is still unknown, although an immune mediated mechanism is thought to be involved.Hematopoietic stem cell transplantation is a well-established treatment for hematological malignancies, but with a growing implication in the treatment of autoimmune diseases. The neurological side effects are probably underdiagnosed.The association of the Parsonage-Turner syndrome and the hematopoietic stem cell transplantation is scarce. We describe two clinical cases of idiopathic brachial plexopathy after hematopoietic stem cell transplantation.The reconstruction of the immune system after a transplant may be the trigger of a brachial plexopathy, but more studies are necessary for the etiology of this disease to be understood and to establish a cause-effect relation with the transplant.

Re-Descemet Membrane Endothelial Keratoplasty (DMEK) con preservación del injerto original tras free roll en cámara anterior: a propósito de un caso / Re-descemet membrane endothelial keratoplasty (DMEK) with preservation of the original graft after free-roll in the anterior chamber: a case report

Introducción: Las queratoplastias lamelares han supuesto un gran impacto en el manejo del edema corneal por disfunción endotelial. Las técnicas de trasplante mínimamente invasivo como la Descemet Membrane Endothelial Keratoplasty (DMEK) han permitido reducir la morbilidad que suponía la realización de una queratoplastia penetrante en este tipo de pacientes. Aun así, se trata de técnicas complejas que no están exentas de complicaciones, y que requieren una larga línea de aprendizaje quirúrgico y una aún más exigente experiencia en el manejo postoperatorio.Caso clínicoUna mujer de 89 años afecta de distrofia endotelial de Fuchs e intervenida de cirugía combinada de catarata y DMEK, presentó a las 24h de la intervención un edema estromal de predominio inferior y un despegamiento sectorial del injerto. Tras un re-bubbling en consultas y 4 días más tarde, se observó el injerto enrollado y libre en cámara anterior.Se intervino de re-DMEK con preservación del injerto original tras 24h, con desepitelización para optimizar la visualización. Se tiñó el injerto con azul tripán y se protegió el estroma posterior con aire. Se reimplantó el injerto bajo maniobras intraoculares y con burbuja de aire.A las 24h de la cirugía se observó el injerto adherido, con una gran disminución del edema estromal. Un mes después, la paciente presentaba una córnea transparente, una persistente adhesión completa del injerto y una agudeza visual de 0,9.ConclusiónEl hallazgo del free roll en cámara anterior tras cirugía de DMEK constituye la forma más compleja de despegamiento del injerto. El edema corneal, así como la disposición de las diferentes estructuras intraoculares son condicionantes a tener en cuenta para la resolución quirúrgica de esta complicación. En muchos casos el reposicionamiento quirúrgico del injerto es factible, hecho que implica ahorrar costes sin necesidad de utilizar nuevos tejidos corneales donantes. (AU)

Introduction: Lamellar keratoplasties have had a great impact in the management of corneal edema due to endothelial dysfunction. Minimally invasive transplant techniques such as descemet membrane endothelial keratoplasty (DMEK) have helped to reduce the morbidity involved in performing penetrating keratoplasty in this type of patient. Even so, these are complex techniques that are not free of complications and require a long line of surgical learning and an even more demanding experience in postoperative management.Clinical caseAn 89-year-old woman suffering from Fuchs endothelial dystrophy and undergoing combined cataract and DMEK surgery presented stromal edema predominantly inferior and sectoral detachment of the graft 24h after the intervention. After re-bubbling in consultations and 4 days later, the graft was observed rolled and free in the anterior chamber.She underwent re-DMEK with preservation of the original graft after 24h, with de-epithelialization to optimize visualization. The graft was stained with trypan blue and the posterior stroma was protected with air. The graft was reimplanted under intraocular maneuvers and with an air bubble.Twenty four hours after surgery, the adhered graft was observed, with a great decrease in stromal edema. One month later, the patient had a clear cornea, persistent complete graft adhesion, and visual acuity of 0.9.ConclusionThe discovery of free roll in the anterior chamber after DMEK surgery constitutes the most complex form of graft detachment. Corneal edema as well as the arrangement of the different intraocular structures are conditions to be considered for the surgical resolution of this complication. In many cases, surgical repositioning of the graft is feasible, which means saving costs without the need to use new donor corneal tissues. (AU)

The role of allergic and nonallergic rhinitis on success of type 1 cartilage tympanoplasty / El papel de la rinitis alérgica y no alérgica en el éxito de la timpanoplastia de cartílago tipo 1

Objective: To investigate the role of allergic rhinitis (AR) and non-allergic rhinitis (NAR) on success of type 1 cartilage tympanoplasty. Methods: This prospective study was conducted on 60 patients who had type 1 cartilage tympanoplasty. The patients were divided into three groups as no-rhinitis (n = 28), NAR (n = 18) and AR (n = 14) groups, based on their symptoms, skin prick tests and/or serum specific IgE levels. AR and NAR groups were treated for their rhinitis symptoms both pre- and postoperatively. The patients were followed up for a minimum of 6 months and compared for graft success rates and audiological outcomes. Results: Three study groups were similar for age, gender distributions and preoperative air-bone gaps (p = 0.780, p = 0.167 and p = 0.676, respectively). Postoperative graft perforation rate was 0% in no-rhinitis and AR groups while it was 16.7% in NAR group, with a significant difference among three groups (p = 0.034). The comparison of three study groups for change in the postoperative air bone gaps in comparison with preoperative air bone gaps did not yield any statistically significant result (p = 0.729). Conclusion: Although AR does not result in failure of type 1 cartilage tympanoplasty in patients treated for rhinitis compared to the control group, NAR does. Pre- and postoperative treatment of patients for rhinitis and employment of cartilage graft may be the key factors for success of surgery in patients with AR. Further studies with a larger sample size are needed.(AU)

Objetivo: Investigar el papel de la rinitis alérgica (AR) y la rinitis no alérgica (NAR) en el éxito de la timpanoplastia de cartílago tipo 1. Métodos: Este estudio prospectivo se realizó en 60 pacientes con timpanoplastia de cartílago tipo 1. Los pacientes se dividieron en tres grupos como libres de rinitis (n = 28), NAR (n = 18) y AR (n = 14) según sus síntomas, pruebas cutáneas y/o niveles de IgE específica en suero. Los grupos AR y NAR fueron tratados antes y después de la operación por síntomas de rinitis. Los pacientes fueron seguidos durante al menos 6 meses y se compararon las tasas de éxito del injerto y los resultados audiológicos. Resultados: Los tres grupos de estudio fueron similares en cuanto a la edad, la distribución por sexos y el espacio entre el aire y el hueso preoperatorio (p = 0,780, p = 0,167 y p = 0,676, respectivamente). Mientras que la tasa de perforación del injerto postoperatorio fue del 0 % en el grupo sin rinitis y AR, fue del 16,7 % en el grupo NAR, y hubo una diferencia significativa entre los tres grupos (p = 0,034). La comparación de los tres grupos de estudio con los espacios óseos aéreos preoperatorios para el cambio en los espacios óseos aéreos posoperatorios no arrojó un resultado estadísticamente significativo (p = 0,729). Conclusión: Aunque AR no falla en la timpanoplastia de cartílago tipo 1 en pacientes tratados por rinitis en comparación con el grupo control, NAR sí lo hace. El tratamiento pre y postoperatorio de pacientes con rinitis y el uso de injertos de cartílago pueden ser factores clave para el éxito de la cirugía en pacientes con RA. Se necesitan más estudios con tamaños de muestra más grandes.(AU)

Evolución de la técnica follicular unit extraction (FUE) / Evolution of the follicular unit extraction (FUE) technique

El microtrasplante capilar, método FUE, es la cirugía para la recuperación capilar que consta en la extracción de unidades foliculares con punches de distintos diámetros y longitudes, desde una zona llamada dadora, generalmente occipital y/o temporal aunque pueden utilizarse otras partes del cuerpo como barba, tórax, abdomen y pubis, para luego de seleccionarse y conservarse en forma adecuada ser implantadas en la llamada zona receptora. Tanto los avances en la técnica como en el uso de instrumental de última generación generan resultados mejores y más naturales, con una recuperación más rápida y menor daño de sus zonas dadoras.

Hair transplant, FUE method, is surgery for hair recovery that consists of the extraction of follicular units with punches of different diameters and lengths, from an area called the donor; usually occipital and/or temporal; although they can be used on other parts of the body such as beard, thorax, abdomen and pubes. After being appropriately selected and preserved, they are implanted in the so-called receiving area. Both advances in technique and in the use of cutting-edge instruments generate better and more natural results, with faster recovery and less damage to the donor areas

Doar ou não doar: significados da negação familiar para a doação de órgãos e tecidos / To donate or not to donate: meanings of family refusal to the refusal to donate organs and tissues

Objetivo: Compreender os significados atribuídos por familiares sobre a negação para a doação de órgãos e tecidos. Métodos: Estudo descritivo, exploratório, com abordagem qualitativa. Utilizou-se um questionário semiestruturado para a coleta de dados e a análise temática de conteúdo para o tratamento dos dados obtidos. A amostragem de 10participantes foi definida pelo critério de saturação teórica. Resultados: Percebeu-se a tendência de os familiares consentirem a doação quando bem orientados sobre a morte encefálica e de a finalidade humanística do doador, mas os principais obstáculos para a negação da doação são a falta de conhecimento sobre a doação de órgãos, o medo da mutilação do corpo por não saber como é realizado o procedimento de retirada de órgãos e tecidos, a burocracia com a demora na liberação do corpo para sepultamento e a discordância entre os familiares. Conclusão: Os significados da negação familiar permeiam o medo, o sentimento de vazio, a falta de informação sobre os processos que envolvem a doação e captação de órgãos e tecidos, bem como aspectos culturais e religiosos, embora o desespero, a dor e a falta de empatia das equipes de saúde também possam corroborar a recusa. Descritores: Obtenção de Tecidos e Órgãos; Transplante; Relações Familiares

Objective: To understand the meanings attributed by family members about the refusal to donate organs and tissues.Methods: Adescriptive and exploratory study with a qualitative approach. A semi-structured questionnaire was used for data collection and thematic content analysis was employed for the treatment of the data obtained. The sample comprised by 10participants was defined by means of the theoretical saturation criterion. Results: There was a tendency for family members to consent to thedonation when well-oriented about brain death and the humanistic purpose of the donor, but the main obstacles to refuse donation are as follows: lack of knowledge about organ donation, fear of body mutilation for not knowing how the procedure for removingorgans and tissues is performed, bureaucracy with the delay in releasing the body for burial and disagreement between family members.Conclusion:The meanings of family refusal permeate fear, a feeling of emptiness and lack of information about the processes involved in organ and tissue donation, as well as cultural and religious aspects, although despair, pain and lack of empathy of the health teams can also corroborate refusal.Descriptors:Tissue and Organ Procurement; Transplant; Family relationships.

Nefrectomía totalmente laparoscópica para donante vivo de riñón: Características y desenlaces en una institución de alta complejidad en Colombia. Serie de casos / Total laparoscopic nephrectomy for a living kidney donor: Characteristics and outcomes in a single center from Colombia. Case series

Introducción. El trasplante es la mejor opción de tratamiento para los pacientes con enfermedad renal terminal, sin embargo, existe discrepancia entre las listas de espera y la disponibilidad de órganos a partir de la donación cadavérica. Buscando aumentar el número de órganos disponibles se implementó el trasplante con donante vivo. A partir de la introducción de técnicas mínimamente invasivas para la nefrectomía, el donante vivo ha logrado cifras cercanas al 50 % de los trasplantes realizados en muchas instituciones, debido a los beneficios propios del procedimiento. El objetivo de este estudio fue describir los resultados después de la incorporación del procedimiento totalmente laparoscópico en nuestra institución. Métodos. Se hizo un análisis retrospectivo de las características de los pacientes llevados a nefrectomía para obtención de injerto por técnica totalmente laparoscópica y los resultados en un solo centro en Cali, Colombia, desde noviembre de 2019 hasta octubre de 2022. Los datos fueron obtenidos mediante la revisión de las historias clínicas electrónicas. Resultados. Se realizaron 78 nefrectomías para obtención de injerto con técnica totalmente laparoscópica. El tiempo operatorio promedio fue de 152 minutos, el sangrado promedio fue de 12 ml, la estancia hospitalaria promedio del donante fue de 2,8 días. La tasa de complicaciones fue de 7,6 % (4 pacientes con complicación Clavien-Dindo I y 2 pacientes Clavien-Dindo IIIb). No se presentó ningún caso de mortalidad. Conclusiones. La técnica totalmente laparoscópica resulta ser una técnica segura con baja tasa de morbilidad y excelentes beneficios para los donantes.

Introduction. Kidney transplant is the best treatment option for end-stage renal disease. However, the discrepancy between waiting lists and the availability of organs from cadaveric donation is well known. Organ transplantation with a living donor was implemented to increase the number of organs available. Since the introduction of minimally invasive techniques for nephrectomy, living donors have achieved figures close to 50% of transplants performed in many institutions due to the procedure's benefits. In our country, the experiences described are from the hand-assisted technique. This is the first description after incorporating the laparoscopic procedure. Methods. A retrospective analysis of the characteristics and results of all patients undergoing nephrectomy to obtain a graft using a laparoscopic technique was carried at a single center in Cali, Colombia, from November 2019 to October 2022. The electronic medical records were reviewed to obtain the data. Results. Seventy-eight nephrectomies were performed to obtain a graft with a laparoscopic technique. The mean operating time was 152 minutes, the average bleeding was 12 cc, and the average hospital stay was 2.8 days. The complication rate was 7.6% (four patients with Clavien-Dindo I complication and two Clavien-Dindo IIIb patients). There were no cases of mortality. Conclusions. The laparoscopic technique is safe, with a low morbidity rate and excellent benefits.

Introduction: The process of organ and tissue donation is defined by actions to transform a Potential Donor (PD) into an effective donor and begins with the diagnosis of brain death. Objective: To analyze the clinical and sociodemographic profile of potential organ donors, as well as the factors that influence organ donation. Methods: This is a quantitative, cross-sectional, retrospective, and analytical research carried out in a region of Northeast Brazil by collecting data from 455 medical records of patients with brain death, who were diagnosed using a structured form. Subsequently, descriptive analyzes were carried out and for the associations between the independent and dependent variables, the Pearson's chi-square test was used. Results: The age groups with the highest incidence were between 21 to 40 years old and 41 to 60 years old, with a 33.8 % each, with a predominance of males (64.1%). Regarding the cause of death, traumatic brain injury was the most common with a 36.5% of the sample. From the 83.3% of the family members that were interviewed, 53.5% of them authorized the donation. Male potential donors constituted the 59.01% of the authorized donations (positive interviews). There was no relationship between the interview results and the age group of the PD. When correlating the results of family interviews and the cause of death, 40.63% of them were caused by traumatic brain injury and, out of this total, 63.63% had the donation authorized. Conclusion: The most effective donors were young and male whose cause of brain death was traumatic brain injury and whose families allowed the donation.

The Use of the Implantable Doppler Probe as a Blood Flow Monitoring Device in Clinical Settings: A Narrative Review of the Evidence.

OBJECTIVES: In the past decade, the implantable Doppler probe has been studied widely as a blood flow-monitoring device in reconstructive and transplant surgical specialities. Its utility as an effective postoperative monitoring technique is still debatable, with no clear guidelines in clinical practice. Here, we mapped the current evidence on the usefulness of the implantable Doppler probe as a blood flow-monitoring device. The objective was to present an up-to-date assessment of the benefits and limitations of using implantable Doppler probes in clinical and experimental clinical settings. MATERIALS AND METHODS: We conducted a literature search using the Cochrane Library and Healthcare Databases Advanced Search and using implantable Doppler probe, transplant, graft, and flap as key words. The search yielded 184 studies, with 73 studies included after exclusions. We evaluated, synthesized, and summarized the evidence from the studies in tabular form. RESULTS: There is clinical equipoise regarding the effectiveness of implantable Doppler probe as a flow sensing technique. The main reason is the lack of information and gaps in the evidence regarding the benefits and limitations of using implantable Doppler probes in clinical practice. CONCLUSIONS: The implantable Doppler probe has the potentialto be used as an adjunctpostoperativeblood flow-monitoring device. However, keeping in view of technical limitations, its signals should be interpreted alongside traditional clinical assessment techniques to determine the patency of microvascular anastomosis. Although evidence in this review will inform clinical practice in transplant and reconstructive surgical specialties, a prospective randomized controlled study with a larger patient cohort is required to evaluate the effectiveness of this probe in clinical settings.
