[Translated article] Immobilisation with compression bandage vs. antebraquial splint in distal radius fractures operated by open reduction and locking plate. Randomised clinical trial.

INTRODUCTION: Currently, there is a lack of prospective studies to unify criteria about type and time for postoperative immobilisation in surgical distal radius fractures. The aim of this study is to compare functional and radiological results in two groups of distal radius fractures treated with internal fixation with locking plate, and immobilised with antebrachial splint or compression bandage for 3 weeks. MATERIAL AND METHOD: A randomised clinical trial was carried out with two parallel groups with 3, 6, and 12 weeks of follow-up. Main and secondary functional variables were measured, such as pain on VAS scale, values on PRWE, DASH and MRS scale, range of motion in flexion-extension, complications, etc. In addition, some radiological variables were measured at preoperative period and one week after surgery, such as union time, dorsal displacement, shortening, ulnar variance, etc. RESULTS: A total of 62 patients were evaluated: 27 immobilised with bandage and 35 with splint. Analysis of the results obtained showed significant differences in both groups for almost all radiological variables from pre to postoperative period, and for all functional variables from 3 to 12 weeks after surgery. No significant differences were found between the two groups for any of the radiological and functional variables evaluated (VAS 3-12 weeks: p=.584; PWRE 3-12 weeks: p=.248; flexion range of motion 3-12 weeks: p=.959; extension range of motion: p=.50; union time: p=.89). CONCLUSIONS: We do not find clinical or radiological differences between immobilisation with antebrachial splint or compression bandage for distal radius fractures operated with locking plate. A greater number of patients and follow-up are necessary to extrapolate the results to the general population and to establish criteria for good postoperative management of these fractures.

Sticholysin II shows similar immunostimulatory properties to LLO stimulating dendritic cells and MHC-I restricted T cell responses of heterologous antigen.

Induction of CD8+ T cell responses against tumor cells and intracellular pathogens is an important goal of modern vaccinology. One approach of translational interest is the use of liposomes encapsulating pore-forming proteins (PFPs), such as Listeriolysin O (LLO), which has shown efficacy at priming strong and sustained CD8+ T cell responses. Recently, we have demonstrated that Sticholysin II (StII), a PFP from the sea anemone Stichodactyla helianthus, co-encapsulated into liposomes with ovalbumin (OVA) was able to stimulate, antigen presenting cells, antigen-specific CD8+ T cells and anti-tumor activity in mice. In the present study, we aimed to compare StII and LLO in terms of their abilities to stimulate dendritic cells and to induce major histocompatibility complex (MHC) class I restricted T cell responses against OVA. Interestingly, StII exhibited similar abilities to LLO in vitro of inducing dendritic cells maturation, as measured by increased expression of CD40, CD80, CD86 and MHC-class II molecules, and of stimulating OVA cross-presentation to a CD8+ T cell line. Remarkably, using an ex vivo Enzyme-Linked ImmunoSpot Assay (ELISPOT) to monitor gamma interferon (INF-γ) producing effector memory CD8+ T cells, liposomal formulations containing either StII or LLO induced comparable frequencies of OVA-specific INF-γ producing CD8+ T cells in mice that were sustained in time. However, StII-containing liposomes stimulated antigen-specific memory CD8+ T cells with a higher potential to secrete IFN-γ than liposomes encapsulating LLO. This StII immunostimulatory property further supports its use for the rational design of T cell vaccines against cancers and intracellular pathogens. In summary, this study indicates that StII has immunostimulatory properties similar to LLO, despite being evolutionarily distant PFPs.

Derecho de niños, niñas y adolescentes en la práctica clínica: Estrategias de capacitación durante la formación de pediatras / Rights of children and adolescents in clinical practice: Training strategies for pediatricians

Introducción: Los derechos de los niños, niñas y adolescentes (NNA) constituyen aspectos fundamentales durante el ejercicio profesional para todos aquellos que trabajan en salud infantil Objetivo: Comunicar la experiencia educativa: contenidos y estrategia pedagógica para abordarlos de una manera accesible y atractiva, a fin de facilitar el cumplimiento y asegurar la incorporación de conocimientos y valores considerados fundamentales en la formación de un pediatra. Métodos: Se realizó un curso virtual sobre derechos de NNA en la práctica clínica para residentes donde se esperaba: revisar las prácticas profesionales en salud desde la perspectiva de derechos de NNA, incorporar diversos lenguajes y estrategias a las situaciones de comunicación entre niños y profesionales de la salud para garantizar tales derechos. Se realizaron en torno a tres consideraciones pedagógicas: 1) Estructura de portal educativo, 2) lectura hipermedial e interactiva y 3) Retroalimentaciones constructivas. Resultados: Participaron 71 residentes, el 85% de los participantes fueron de 4to año, y el 100% de los mismos lo finalizaron. Conclusiones: La práctica asistencial supervisada ocupa gran parte del tiempo activo del residente. La oferta educativa a distancia a través de plataformas virtuales ofrece una alternativa valiosa siempre que se asegure el acceso y cumplimiento de las actividades; dichas premisas dependen en gran parte del diseño pedagógico y atractivo presentado (AU)

Introduction: The Rights of Children and Adolescents comprise aspects that are fundamental for professionals working in the field of healthcare in children. Objective: To describe the educational experience, contents, and strategy for an accessible and attractive approach to facilitate compliance and assure the incorporation of knowledge and values considered to be essential for the training in pediatrics. Methods: an online course on the Rights of Children and Adolescents in clinical practice for residents with the aim to revise practices of health care professionals for the point of view of Rights of Children and Adolescents, to incorporate different manners of speech and strategies in communication settings involving children and health care professionals to guarantee these rights. Interventions took place in three educational settings: 1) Structure of an educational website, 2) Multimedia and interactive reading, and 3) Constructive feedback. Results: 71 residents participated, 85% of whom were fourth year residents, and 100% completed the study. Conclusions: Supervised patient care makes up a large part of the work time of a resident. Online education through platforms provides a valuable alternative whenever access and compliance to the activities are assured. Compliance largely depends on the design and attractiveness of the material presented (AU)

Hernioplastía inguinofemoral laparoscópica / Laparoscopic inguinofemoral hernioplasty

Se presenta un estudio de hernioplastía inguinofemoral laparoscópico. En 104 pacientes se realizó 124 hernioplastías. Se comunica la estandarización de la técnica, una clasificación anatómica de acuerdo al tamaño del defecto. En todos se utilizó un parche de malla de polipropileno adicionando trozos planos del mismo material en aquellos casos que tenían una dilatación importante del anillo inguinal profundo o una destrucción completa de la pared posterior. No hubo conversión en la serie. La morbilidad fue leve y transitoria. No ha habido morbilidad a largo plazo o escuelas. El 100 por ciento de la serie se ha seguido. Se comentan siete recurrencias precoces en el primer mes
