Background and objective The aim of this work was to evaluate clinical outcomes of patients with biceps brachii tendon rupture who underwent a surgical tendon reconstruction using our own modified double approach technique. Patients The study was performed in 20 patients (21 cases) with biceps brachii tendon rupture. Patients were treated with our own double-approach surgical technique consisting of 2 minimum incisions. After one year follow-up, functional evaluation was assessed using the mayo Elbow Performance Score, muscle strength was estimated with the Medical Research Council questionnaire and pain was evaluated with the Visual Analogic Scale. Range of motion was determined by measuring extension and flexion. Results One year after surgery all patients had returned to sports at the same level they had previously. Visual Analogic Scale was 1.90 ± 0.89 (mean ± standard deviation) and median Mayo Elbow Performance Score was 90 (minimum–maximum: 80–100). Of them, 16 patients (76.2%) showed the highest Medical Research Council score, score 5, while 6 cases (26.1%) still scored 4+. Patients had a mean of 136.67° flexion (95% CI: 134.14°–139.19°) and −7.38° extension (95% CI: −10.04° to −4.72°). Conclusions Double-incision surgical approach for distal biceps brachial tendon rupture anatomical repair is a safe technique, providing results that allow patients muscle recovery and return to sports.

The content of this article focuses on an experience of the subject Environmental Conditioning II of the degree in Foundations of Architecture of the UPV/EHU. Due to the COVID crisis, it was necessary to reorganize the subject, to rethink the teaching methodology and to train in the use of the available computer tools. This course chose to avoid the use of a single tool, and instead tried to take advantage of the potential offered by different tools available at the university or freely available: eGela, Blackboard Collaborate, Youtube and Socrative. During the paper it is exposed for what kind of activities each tool was applied, how the evaluation system was carried out using these tools and also provides a critical view on the strengths and weaknesses of teaching using online tools based on the experience of the 2019/20 academic year. El contenido de este artículo se centra en una experiencia de la asignatura Acondicionamiento Ambiental II del grado en Fundamentos de la Arquitectura de la UPV/EHU. Debido a la crisis del COVID, obligó a reorganizar la asignatura, a repensar la metodología docente y a formarse en el uso de las herramientas informáticas disponibles. Esta asignatura optó por evitar el uso de una única herramienta, sino que se intentó aprovechar el potencial que ofrecían diferentes herramientas que disponía la universidad o que eran de acceso gratuito: eGela, Blackboard Collaborate, Youtube y Socrative. Durante el documento se expone para qué tipo de actividades se ha aplicado cada herramienta, cómo se ha llevado a cabo el sistema de evaluación mediante estas herramientas y también se aporta una visión crítica sobre las fortalezas y debilidades de la enseñanza mediante herramientas online basada en la experiencia del curso 2019/20. Los autores agradecen al Departamento de Arquitectura y al Vicerrectorado de Investigación de la Universidad del País Vasco UPV/EHU por el apoyo financiero prestado para este trabajo.

Resumen Antecedentes y objetivo Recientemente se ha descrito una nueva modalidad de la tecnica de implante de condrocitos autologos sobre membrana de colageno i / iii llamada HD-ACI (High Density Autologous Chondrocyte Implantation) que esta basada en el aumento de la densidad celular. El objetivo de este trabajo fue estudiar la evolucion clinica y la incidencia de la aparicion de edema oseo en pacientes con lesiones de cartilago en la rodilla tratados con HD-ACI al ano y a los 2 anos de la intervencion. Metodos Se trata de un estudio retrospectivo en 40 pacientes con lesiones condrales grado iii - iv . Todos los pacientes fueron tratados con HD-ACI con una dosis celular de 5 × 106 condrocitos/cm2 de lesion. La percepcion subjetiva de la mejora de los sintomas/funcionalidad se valoro mediante la escala del Comite Internacional de Documentacion de la Rodilla (IKDC, International Knee Documentation Committee). La presencia de edema oseo se evaluo a los 6, 12 y 24 meses de seguimiento por resonancia magnetica. Comite Internacional de Documentacion de la Rodilla (IKDC) Resultados Los valores de IKDC mostraron una mejoria significativa a los 12 y 24 meses (p Conclusiones HD-ACI es un tratamiento efectivo y seguro que mejora el dolor, la percepcion clinica y la funcionalidad de la articulacion. No se ha encontrado correlacion entre la presencia de edema oseo y la evolucion clinica de los pacientes.

Background Recently, a new approach of autologous chondrocyte implantation technique (using as biomaterial a collagen type I/III membrane) based on increasing cell density called HD-ACI (high density autologous chondrocyte implantation) has been described. The objective of this paper was to study the clinical outcome and incidence of subchondral bone oedema in patients with cartilage lesions in the knee treated with HD-ACI at 1–2 years of follow-up. Methods This is a retrospective study performed with forty patients with chondral injuries grade III-IV. All patients were treated with HD-ACI with a cellular dose of 5 × 106 chondrocytes/cm2 of lesion. The subjective perception of improvement of symptoms and functionality was measured with the IKDC score (International Knee Documentation Committee). The presence of bone oedema was assessed at 6, 12 and 24 months of follow-up by magnetic resonance imaging. Results IKDC values showed a significant improvement at 12 and 24 months (p Conclusions HD-ACI is an effective and safe treatment that improves pain, clinical perception and functionality of the joint. No correlation was found between the presence of bone oedema and the patients’ clinical outcome.

Resumen Antecedentes y objetivo En este trabajo se estudio la evolucion clinica de pacientes con rotura de tendon del biceps braquial tratados mediante reconstruccion quirurgica segun nuestra propia tecnica de doble incision. Pacientes Se incluyo a 20 pacientes (21 casos) de rotura de tendon del biceps braquial tratados mediante nuestra propia tecnica quirurgica de doble abordaje modificada, consistente en 2 incisiones minimas. La evaluacion funcional se determino mediante la escala Mayo Elbow Performance Score, la fuerza muscular se determino con el cuestionario Medical Research Council y el dolor mediante la Escala Analogica Visual a los 12 meses de seguimiento. Se determino el rango de movilidad midiendo los grados de flexion y extension. Resultados Un ano despues de la cirugia todos los pacientes habian vuelto al deporte al mismo nivel que tenian previamente. La puntuacion de Escala Analogica Visual fue de 1,90 ± 0,89 (media ± desviacion estandar) y la mediana de la escala Mayo Elbow Performance Score de 90 (minimo-maximo: 80-100). Del total, 16 (76,2%) presentaron la maxima puntuacion en la escala Medical Research Council (puntuacion 5), mientras que 5 casos (23,81%) tuvieron una puntacion de 4+. La media de extension fue de 136,67° (IC 95%: 134,14°-139,19°) y −7,38° de flexion (IC 95%: [−10,04°]-[−4,72°]). Conclusiones El abordaje quirurgico de la doble incision para la reparacion anatomica de las roturas de tendon distal del biceps braquial es seguro y proporciona resultados que permiten la recuperacion muscular y la vuelta al deporte de los pacientes.

Acute and chronic liver dysfunction is common after allogeneic bone marrow transplantation (BMT). Although toxicity, graft versus-host disease (GVHD), and viral infections are the major causes, etiologic diagnosis is difficult and often remains unknown. We conducted a prospective study to establish the role of the infection with both the hepatitis C virus (HCV) and the recently discovered hepatitis G virus (HGV) in liver dysfunction after BMT. From January 1994 to December 1995, 59 patients who had undergone an allogeneic BMT at our institution were enrolled in the study. HGV-RNA was identified in serum by nested polymerase chain reaction (PCR), and HCV was studied by the presence of second generation enzyme-linked immunosorbent assay (ELISA)-antibodies and HCV-RNA by nested PCR. HGV-RNA was detected in 25 patients (42%) (before BMT in 18 and after BMT in 7). HCV-RNA was present in 12 patients (20%) (before BMT in 11 and after BMT in one). The presence of HCV-RNA and HGV-RNA was clearly associated with a previous history of blood transfusions. No significant association was found between viral infection and acute liver toxicity. Some degree of liver dysfunction was present 6 months after BMT in 25 of 40 evaluable patients (62%). Long-term liver dysfunction was more common among patients infected with HCV alone (3 of 4) or with both HCV and HGV (3 of 3) than in those infected with either HGV alone (eight of 13) or with no virus infection (10 of 20). We found a high prevalence of HGV infection in our BMT population. However, no role for HGV in liver disease could be established in this study, and the relationship between HGV infection and liver dysfunction requires further clarification.

Endarteriectomy is an operation originally proposed by Dos Santos in which a thrombus and the portion of the arterial wall to which it is attached are removed and the lumen of the artery re-established. The technic of this operation is described. Case histories of several patients illustrating the results which the authors have obtained are presented.
