Resultados a 3 años tras técnica de reconstrucción anatómica semitendinoso-recto interno 4 fascículos del ligamento cruzado anterior en las mujeres: estudio de casos y controles / Outcome of 4-strand semitendinosus-gracilis anterior ligament reconstruction in women: A matched-cohort study

Introducción: Las mujeres presentan un riesgo elevado de rotura del ligamento cruzado anterior (LCA). Sin embargo, los resultados tras la cirugía reconstructiva son dispares en la literatura. El propósito de este estudio fue analizar los resultados en las mujeres tras cirugía reconstructiva del LCA, y compararlos con los resultados de los hombres. Material y métodos: Estudio retrospectivo de una base de datos prospectiva de pacientes intervenidos mediante reconstrucción anatómica semitendinoso-recto interno 4 fascículos del LCA entre enero de 2017 y diciembre de 2018. Para la valoración de los pacientes se utilizó la escala de actividad deportiva de Tegner, la escala de Lysholm, la escala EVA y el formulario IKDC subjetivo y objetivo. Se determinó la significación clínica con la diferencia mínima clínicamente importante y el estado de síntomas aceptable del paciente. Resultados: Se incluyeron en el estudio 33 mujeres y 99 hombres. El seguimiento medio de los pacientes fue de 36 meses. Las puntuaciones se incrementaron significativamente en los cuestionarios de valoración funcional en las mujeres al final del seguimiento, con resultados similares a los hombres. Solo se detectó una menor puntuación media significativa en las mujeres en el cuestionario IKDC subjetivo en aquellas menores de 25 años comparadas con los hombres. El porcentaje de pacientes que alcanzaron la significación clínica fue similar entre mujeres y hombres. Conclusiones: A los 3 años de seguimiento tras la reconstrucción anatómica semitendinoso-recto interno 4 fascículos del LCA, las mujeres presentaron una mejoría con significación estadística y clínica en los cuestionarios de valoración, sin diferencias con respecto a los hombres.(AU)

Introduction: Women carry out a greater risk of anterior cruciate ligament (ACL) rupture. However, outcomes following ACL reconstruction remain unclear. The aim of this study was to analyze the outcomes in women following ACL reconstruction and compare these outcomes with men. Material and methods: Retrospective study of a prospective database of patients treated with ACL reconstruction between January 2017 and December 2018. Outcome measures included Tegner activity scale, Lysholm scale, EVA scale, and IKDC evaluation form. Clinical significance was measured with minimally clinical important difference, and patient acceptable symptom state. Results: A total of 33 women were matched with 99 men. The mean follow-up was 36 months. Women showed significant improvement from preoperative PROs to the latest follow-up, with no differences between groups. In patients under 25 years old, there was less significant IKDC subjective score in women compared to men. There were no significant differences in frequency of patients achieving MCID and PASS in women compared with men. Conclusions: At 3-year following 4-strand semitendinosus-gracilis anterior ligament reconstruction, women showed significant improvements in PROs, with no differences compared to men.(AU)

Psychological readiness to return to sports after anterior cruciate ligament reconstruction in amateur sport. / Preparación psicológica para la reincorporación deportiva tras cirugía reconstructiva del ligamento cruzado anterior en el deportista aficionado.

INTRODUCTION: Return to sports (RTS) is maybe the main expectation for the patient after anterior cruciate ligament reconstruction (ACLR). The aim of this study was to analyze the psychological readiness to RTS in a cohort of amateur sports after ACLR. MATERIAL AND METHODS: Retrospective study of a prospective database of patients treated with ACLR performed between January and December 2017. Psychological readiness to RTS after ACLR was evaluated with the short version of the Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) scale. RESULTS: A total of 43 patients met the inclusion criteria. The mean age of the patients was 24.7 years. The mean follow-up was 32.5 months. All patients practiced any type of sports at final follow-up. The mean ACL-RSI score was 71.5. Fear of reinjury was mentioned by 14 patients (32.5%). Twenty-four patients (55.8%) pointed out that they did not practice sport at the pre-injury level. The mean ACL-RSI score was statistically significant lower in this group of patients (59.7 vs 87.3; P<.001). CONCLUSIONS: Fear of reinjury keeps after ACLR. Patients that they did not practice sport at the pre-injury level show lower scores in ACL-RSI for RTS.

[Results of arthroscopic treatment of rotator cuff rupture in patients over 60 years of age]. / Resultados del tratamiento artroscópico de la rotura del manguito rotador en pacientes mayores de 60 años.

INTRODUCTION: Increasing life expectancies in population increase the number of patients with rotator cuff tears. The purpose of this study was to evaluate clinical outcomes after arthroscopy rotator cuff repair in patients over 60 years old. We hypothesized that shoulder arthroscopy would allow significant improvements in clinical outcomes without serious complications. MATERIAL AND METHODS: We screened from our shoulder arthroscopy database patients older than 60 years old, with rotator cuff tear, and minimun 2-year follow-up. The patients were evaluated using Constant scores for clinical outcomes and Quick-DASH score for quality of life. RESULTS: In total, 42 patients were enrolled in the study with a mean age of 66.7 years old (range 60 to 83). A double-row repair was indicated in 25 patients (59.5%), and single-row repair in 17 patients (40.5%). As associated injuries we found proximal biceps pathology in 31 patients (48.4%), subscapularis tears in 24 patients (37.5%), and SLAP tears in 3 patients (7.1%). Mean follow-up was 32.4 months. Constant scores improved from 48.3 preoperatively to 87.2 at final follow-up. Quick-DASH decreased from 52.5 preoperatively to 11.0 at final follow-up. DISCUSSION: Arthroscopy cuff repair in patients older than 60 years old provides satisfactory clinical outcomes without morbidity at medium follow-up.

ANTECEDENTES: El aumento de la esperanza de vida de la población incrementa el número de pacientes con patología sintomática del manguito rotador. Nuestro objetivo fue determinar los resultados clínicos de una cohorte de pacientes mayores de 60 años con rotura del manguito rotador intervenidos mediante cirugía artroscópica de hombro (CAH). La hipótesis de trabajo fue que la CAH permitiría resultados clínicos satisfactorios. MATERIAL Y MÉTODOS: De nuestra base de datos prospectiva de CAH seleccionamos los pacientes con: edad mayor de 60 años, rotura de manguito rotador, seguimiento mínimo de dos años. La valoración clínica se determinó según el test de Constant y el cuestionario Quick-DASH de calidad de vida. RESULTADOS: 42 pacientes con una edad media de 66.7 años (rango de 60 a 83). La rotura del supraespinoso se reparó con sutura en doble fila en 25 pacientes (59.5%) y en fila única en 17 pacientes (40.5%). Lesiones asociadas: lesión de la porción larga del bíceps en 31 pacientes (48.4%), del subescapular en 24 pacientes (37.5%) y lesión tipo SLAP en tres pacientes (7.1%). El seguimiento medio fue de 32.4 meses. La puntuación media en la escala de Constant pasó de 48.3 puntos en el preoperatorio a 87.2 puntos al final del seguimiento. El cuestionario DASH síntomas/discapacidad disminuyó de 52.5 de media a 11.0 al final del seguimiento. DISCUSIÓN: El tratamiento artroscópico de las roturas de manguito rotador en mayores de 60 años permite obtener resultados satisfactorios en los cuestionarios de valoración funcional y calidad de vida a mediano plazo.

Estudio de cohortes comparativo del abordaje Superpath con abordaje convencional posterior en cirugía protésica primaria de cadera no cementada: curva de aprendizaje y resultados a corto plazo / Comparative cohort study of the SuperPath approach and the conventional posterior approach in primary cementless hip replacement surgery

Antecedentes y objetivo: En la actualidad no existe un consenso sobre cuál es el mejor abordaje de cadera para implantar una prótesis. Sin embargo, sí existe una tendencia a reducir al máximo la lesión sobre los tejidos periarticulares, lo cual puede influir en los resultados a corto plazo. El abordaje Superpath permite el acceso a la articulación manteniendo la integridad de los rotadores externos. El objetivo de nuestro estudio fue comparar los resultados a corto plazo del abordaje Superpath con el abordaje convencional posterior. Materiales y métodos: Estudio prospectivo de cohorte de 30 pacientes intervenidos mediante abordaje Superpath pareados por sexo, edad, índice de masa corporal y valoración clínica, con 60 pacientes intervenidos mediante abordaje convencional posterior. La valoración clínica se realizó mediante la escala de Harris, Merle d'Aubigné, Womac para el dolor y la función, SF-12 físico y mental, HOS-AVD e IHOT-12. Radiológicamente se determinó el ángulo de inclinación acetabular, alineación del vástago femoral e integración de los implantes. Resultados: No hubo diferencias significativas entre ambas cohortes con respecto a las variables preoperatorias. El tiempo quirúrgico, el descenso medio de Hb y Hto y la pérdida sanguínea fue mayor en la cohorte Superpath. La estancia hospitalaria fue similar. Los cuestionarios de valoración clínica mostraron incrementos significativos entre los valores preoperatorios y a los 12 meses en ambas cohortes. El cuestionario IHOT-12 a los 3 meses, el cuestionario SF-12 físico y el cuestionario SF-12 mental a los 12 meses, mostró mayores puntuaciones en la cohorte Superpath, siendo las diferencias significativas. Radiológicamente no se detectaron diferencias entre ambas cohortes. Conclusiones: La curva de aprendizaje del abordaje Superpath presenta unos resultados clínicos y radiológicos similares al abordaje posterior durante el primer año tras la prótesis total de cadera. A destacar la necesidad de un mayor tiempo quirúrgico y un mayor sangrado en los pacientes

Background and objectives: There is no current consensus on the most suitable hip approach. However, there is a trend to reduce damage to soft tissue, which may have an influence on early outcomes. The SuperPath approach accesses the capsule maintaining integrity of the external rotators. The purpose of this study was to compare the SuperPath approach with the conventional posterior approach, in terms of early outcomes and radiological results. Material and methods: A cohort of 30 patients operated using the SuperPath approach was prospectively matched for age, gender, body mass index and hip function with 60 patients operated using a conventional posterior approach. Clinical evaluation was performed by the Harris score, Merle d'Aubigné score, reduced Western Ontario and McMasters Universities (WOMAC), Short-Form 12 (SF12), IHOT-ADV and IHOT-12 questionnaires. Radiological evaluation was also performed. Results: Preoperatively, no significant differences were detected between cohorts. Skin-to-skin operation time and blood loss was higher in the SuperPath cohort. Length of stay was similar between cohorts. Clinical evaluation improved significantly from the preoperative values to the 1-year follow-up. At 3 months the SuperPath cohort showed better results for IHOT-12, and at 12 months for SF. Radiologically, there were no differences between cohorts. Conclusion: This prospective randomized study reveals that the learning curve for the SuperPath approach provides similar outcomes to the conventional posterior approach within the first year after surgery. The Superpath approach was associated with longer skin-to-skin operation time, and greater blood loss

Arthroscopic hip surgery with a microfracture procedure of acetabular full-thickness chondral damage. Cohort study with a 3-year follow-up. / Tratamiento artroscópico mediante microfracturas de la lesión cartilaginosa acetabular de espesor completo. Estudio de cohortes con seguimiento medio a 3 años.

INTRODUCTION AND PURPOSE: Management of injuries to the articular cartilage is complex and challenging. Our purpose was to assess outcomes of a cohort of patients who underwent hip arthroscopy with full-thickness chondral damage treated with microfracture and compare these outcomes with those from a similar cohort of patients who did not. MATERIAL AND METHODS: We prospectively gathered the data of 31 hips treated with microfracture from January 2009 to January 2016. In the cohort of hips without chondral damage there were 49 hips. All patients were assessed pre- and postoperatively with 4 patient-reported outcome instruments. RESULTS: The mean follow-up was 36.2 months in the cohort of patients with full-thickness chondral damage, and 36.6 months in the cohort of patients without chondral damage. Both groups demonstrated significant improvement in all patient-reported outcome instruments between preoperative and final follow-up. There was no statistically significant difference between both cohorts at final follow-up. DISCUSSION: This study showed that patients undergoing microfracture during hip arthroscopy had significant improvement in all patient-reported outcome instruments during follow-up. The greatest improvement was noted at 6 months postoperatively. Both groups showed no significant difference in final patient-reported outcome instruments scores.

Rigidez postraumática de codo: resultados a corto plazo de la artrólisis artroscópica / Post-traumatic elbow stiffness: arthroscopic release, short-term results

Resumen: Antecedentes: La «artrólisis¼ abierta ha sido el tratamiento estándar en la rigidez de codo, con buenos resultados; sin embargo, las complicaciones asociadas y los avances en la cirugía artroscópica han permitido incorporar esta técnica quirúrgica. Material y métodos: Entre Enero de 2014 y Marzo de 2016, seis pacientes con rigidez postraumática de codo fueron intervenidos mediante cirugía artroscópica por el mismo equipo quirúrgico. Se registró pre- y postoperatoriamente, el nivel de dolor según escala analógica visual numérica, rango de movilidad articular del codo con el uso de un goniómetro y cuestionario Mayo Elbow Performance Index. Resultados: El seguimiento medio de los pacientes fue de 14.5 meses. El valor medio en la escala analógica visual disminuyó de 4.5 a 0.3 puntos. El rango medio de movilidad del codo se incrementó de 55.3o a 130o, con una ganancia media de 75o. La puntuación media en el cuestionario MEPI pasó de 46.6 puntos a 95 puntos, con una ganancia media de 48.4 puntos. Como procedimientos asociados a la «artrólisis¼ artroscópica se realizó extracción del material de síntesis en las tres fracturas de olécranon. No hubo ningún caso de osificación heterotópica, infección superficial o neuropatía cubital. Ningún paciente precisó reintervención quirúrgica para una nueva «artrólisis¼ artroscópica o abierta. Conclusiones: La liberación artroscópica en la rigidez postraumática de codo es una técnica efectiva a corto plazo para recuperar la movilidad.

Abstract: Background: Open «arthrolysis¼ has been the standard treatment for elbow stiffness, with good results. However, the associated complications of open arthrolysis and the advancements in arthroscopic surgery have allowed including the latter as an additional approach. Material and methods: Between January 2014 and March 2016, 6 patients with posttraumatic elbow stiffness underwent arthroscopic surgery by the same surgical team. Pre- and post-operative assessment included pain with a numerical visual analogue scale, elbow joint range of motion with a goniometer and the Mayo Elbow Performance Index questionnaire. Results: Mean patient follow-up was 14.5 months. The mean VAS score decreased from 4.5 to 0.3. The mean elbow range of motion increased from 55.3o to 130o, with a mean gain of 75o. The mean MEPI questionnaire score went from 46.6 to 95, with a mean gain of 48.4 points. The procedures associated with arthroscopic «arthrolysis¼ included removal of the synthesis material from the 3 olecranon fractures. No cases of heterotopic ossification, superficial infection or ulnar neuropathy were reported. None of the patients required surgical reintervention to perform a new «arthrolysis¼, whether arthroscopic or open. Conclusions: Arthroscopic release to treat posttraumatic elbow stiffness is an effective technique to restore mobility in the short term.

El grado de degeneración articular era Tönnis 0 en 103 caderas y Tönnis 1 en 52 caderas. En 109 caderas (70,3%) se detectó lesión cartilaginosa del reborde acetabular. La localización de las lesiones fue superior y anterior. El análisis estadístico estableció como factores preoperatorios independientes para la presencia de lesión cartilaginosa del reborde acetabular un ángulo alfa igual o mayor de 55°, un tiempo de evolución de los síntomas hasta la artroscopia igual o mayor de 20 meses, y un nivel de actividad física en la escala de Tegner igual o mayor de 6. Discusión. A pesar de que los pacientes se clasificaron como Tönnis 0 y 1, y que la resonancia nuclear magnética de 3tesla informó de la presencia de lesión cartilaginosa en el 1,3% de los casos, existía una alta frecuencia de lesiones cartilaginosas del reborde acetabular. El conocimiento de los factores predictores preoperatorios asociados a la lesión cartilaginosa del reborde acetabular puede ayudar al cirujano ortopédico sobre la indicación de la cirugía artroscópica de cadera (AU)

Introduction and purpose. Articular cartilage lesions have a direct effect on the success of surgical treatment. The aim of this study was to determine the prevalence rate, location, grade, and factors associated with acetabular rim articular cartilage lesions in patients undergoing hip arthroscopy. Material and methods. A prospective study was conducted by analysing the intraoperative data of 152 hips in 122 patients treated with hip arthroscopy for femoroacetabular impingement from January 2011 to May 2016. The prevalence rate, location, and grade were calculated, as well as the pre-operative factors associated with acetabular rim articular cartilage lesions. Results. The mean age of the patients was 38.6 years. The Tönnis grade was 0 in 103 hips, and 1 in 52 hips. Acetabular rim articular cartilage lesions were present in 109 (70.3%) hips. The location of the lesions was superior-anterior. Independent risk factors for the presence of acetabular rim articular cartilage lesions were an alpha-angle equal or greater than 55°, duration of symptoms equal or greater than 20 months, and Tegner activity scale level equal or greater than 6. Discussion. Although patients were classified as Tönnis grade 0 and 1, and 3tesla MRI reported acetabular lesions in 1.3% of cases, there was a high frequency of acetabular rim cartilage lesions. Knowledge of the independent risk factors associated with acetabular rim articular cartilage lesions may assist the orthopaedic surgeon with the decision to perform hip arthroscopy (AU)

[Post-traumatic elbow stiffness: arthroscopic release, short-term results]. / Rigidez postraumática de codo: resultados a corto plazo de la artrólisis artroscópica.

BACKGROUND: Open «arthrolysis¼ has been the standard treatment for elbow stiffness, with good results. However, the associated complications of open arthrolysis and the advancements in arthroscopic surgery have allowed including the latter as an additional approach. MATERIAL AND METHODS: Between January 2014 and March 2016, 6 patients with posttraumatic elbow stiffness underwent arthroscopic surgery by the same surgical team. Pre- and post-operative assessment included pain with a numerical visual analogue scale, elbow joint range of motion with a goniometer and the Mayo Elbow Performance Index questionnaire. RESULTS: Mean patient follow-up was 14.5 months. The mean VAS score decreased from 4.5 to 0.3. The mean elbow range of motion increased from 55.3o to 130o, with a mean gain of 75o. The mean MEPI questionnaire score went from 46.6 to 95, with a mean gain of 48.4 points. The procedures associated with arthroscopic «arthrolysis¼ included removal of the synthesis material from the 3 olecranon fractures. No cases of heterotopic ossification, superficial infection or ulnar neuropathy were reported. None of the patients required surgical reintervention to perform a new «arthrolysis¼, whether arthroscopic or open. CONCLUSIONS: Arthroscopic release to treat posttraumatic elbow stiffness is an effective technique to restore mobility in the short term.

ANTECEDENTES: La «artrólisis¼ abierta ha sido el tratamiento estándar en la rigidez de codo, con buenos resultados; sin embargo, las complicaciones asociadas y los avances en la cirugía artroscópica han permitido incorporar esta técnica quirúrgica. MATERIAL Y MÉTODOS: Entre Enero de 2014 y Marzo de 2016, seis pacientes con rigidez postraumática de codo fueron intervenidos mediante cirugía artroscópica por el mismo equipo quirúrgico. Se registró pre- y postoperatoriamente, el nivel de dolor según escala analógica visual numérica, rango de movilidad articular del codo con el uso de un goniómetro y cuestionario Mayo Elbow Performance Index. RESULTADOS: El seguimiento medio de los pacientes fue de 14.5 meses. El valor medio en la escala analógica visual disminuyó de 4.5 a 0.3 puntos. El rango medio de movilidad del codo se incrementó de 55.3o a 130o, con una ganancia media de 75o. La puntuación media en el cuestionario MEPI pasó de 46.6 puntos a 95 puntos, con una ganancia media de 48.4 puntos. Como procedimientos asociados a la «artrólisis¼ artroscópica se realizó extracción del material de síntesis en las tres fracturas de olécranon. No hubo ningún caso de osificación heterotópica, infección superficial o neuropatía cubital. Ningún paciente precisó reintervención quirúrgica para una nueva «artrólisis¼ artroscópica o abierta. CONCLUSIONES: La liberación artroscópica en la rigidez postraumática de codo es una técnica efectiva a corto plazo para recuperar la movilidad.

La cirugía artroscópica de cadera en deportistas varones menores de 40 años con choque femoroacetabular: resultado a corto plazo / Hip arthroscopy in males younger than 40 with femoroacetabular impingement: short-term outcomes

Introducción y objetivos. El choque femoroacetabular es el mecanismo más común descrito en la literatura que conduce a la lesión del labrum y del cartílago articular en la cadera no displásica. Nuestro objetivo fue determinar los resultados clínicos y radiológicos de la cirugía artroscópica de cadera como tratamiento del choque femoroacetabular en pacientes jóvenes con alta demanda funcional. Material y métodos. Estudio prospectivo de 41 pacientes menores de 40 años tratados mediante cirugía artroscópica de cadera por choque femoroacetabular. Para valoración clínica se utilizaron la escala modificada de Harris, cuestionarios de valoración HOS e IHOT12. Se realizó una valoración radiológica para determinar altura articular y ángulo alfa. Resultados. La edad media de los pacientes fue de 32,7 años. Se detectó lesión del labrum en el 78% y del cartílago acetabular en el 56% de los casos. El seguimiento medio de los pacientes fue de 31,3 meses. Hubo una mejora significativa en la puntuación media en los cuestionarios de valoración clínica. Radiológicamente no se modificó la altura media del espacio articular, con reducción significativa a valores normales del ángulo alfa. Todos los pacientes se reincorporaron a su actividad deportiva habitual previa. Discusión. La cirugía artroscópica de cadera ha permitido la mejoría clínica de los pacientes con corrección de la deformidad ósea, lesión labral y cartilaginosa, y reincorporación de los pacientes a sus actividades deportivas previas a la cirugía. Es fundamental un mayor seguimiento para confirmar la estabilidad de los resultados clínicos y radiológicos obtenidos (AU)

Introduction and objectives. Femoroacetabular impingement is probably the most common mechanism that leads to the development of early cartilage and labral damage in the non-dysplastic hip. The objective was to evaluate the outcomes of hip arthroscopy as a treatment for femoroacetabular impingement in patients with high level of function. Material and methods. A prospective study was performed on 41 patients younger than 40 years old undergoing hip arthroscopy for femoroacetabular impingement. Modified Harris Hip Score and HOS and IHOT questionnaires were used for clinical assessment. Radiological evaluation was made for joint space and alpha angle. Results. The mean age of patients was 32.7 years. Labrum injury was detected in 78%, and acetabular cartilage injury in 56% of cases. The average follow-up was 31.3 months. There was a significantly improvement in the mean score in the clinical questionnaires. Radiologically there was no change in the mean joint space, with significantly reduction to normal values of the alpha angle. All patients returned to sports at their pre-injury level of function. Discussion. Hip arthroscopy resulted in improvement in hip functional outcomes with correction of the underlying osseous deformity and treatment of the associated labral and cartilage pathology, with the return of patients to their pre-injury sports. Further follow-up is essential to confirm the stability of the clinical and radiological outcomes (AU)

Temporal regularity determines the impact of electrical stimulation on tactile reactivity and response to capsaicin in spinally transected rats.

Nociceptive plasticity and central sensitization within the spinal cord depend on neurobiological mechanisms implicated in learning and memory in higher neural systems, suggesting that the factors that impact brain-mediated learning and memory could modulate how stimulation affects spinal systems. One such factor is temporal regularity (predictability). The present paper shows that intermittent hindleg shock has opposing effects in spinally transected rats depending upon whether shock is presented in a regular or irregular (variable) manner. Variable intermittent legshock (900 shocks) enhanced mechanical reactivity to von Frey stimuli (hyperreactivity), whereas 900 fixed-spaced legshocks produced hyporeactivity. The impact of fixed-spaced shock depended upon the duration of exposure; a brief exposure (36 shocks) induced hyperreactivity whereas an extended exposure (900 shocks) produced hyporeactivity. The enhanced reactivity observed after variable shock was most evident 60-180 min after treatment. Fixed and variable intermittent stimulation applied to the sciatic nerve, or the tail, yielded a similar pattern of results. Stimulation had no effect on thermal reactivity. Exposure to fixed-spaced shock, but not variable shock, attenuated the enhanced mechanical reactivity (EMR) produced by treatment with hindpaw capsaicin. The effect of fixed-spaced stimulation lasted 24h. Treatment with fixed-spaced shock also attenuated the maintenance of capsaicin-induced EMR. The results show that variable intermittent shock enhances mechanical reactivity, while an extended exposure to fixed-spaced shock has the opposite effect on mechanical reactivity and attenuates capsaicin-induced EMR.

Two weeks of postsurgical therapy may be enough for high-risk cases of endocarditis caused by Streptococcus viridans or Streptococcus bovis.

The duration of antimicrobial therapy after surgery for infective endocarditis (IE) is controversial. A short course of postsurgical therapy is currently accepted only for patients with negative valve culture. We performed a retrospective (1994-2008) analysis of patients who underwent surgery for IE in our hospital and had a high risk of complications ( one of more of the following: <2 weeks of antibiotic treatment before surgery; embolism; perivalvular extension; and positive valve culture) to compare outcomes of patients who received short-course antimicrobial therapy (SAT) (median 15 days) or long-course antimicrobial therapy (LAT) (median 32 days), irrespective of the results of valve culture. Our endpoints included length of hospital stay, renal and hepatic failure, relapse, re-infection, and mortality rates 1 year after surgery. During the study period, 140 patients underwent surgery for IE (valve replacement, 87.9%). Of these, 133 fulfilled the high-risk group criteria and 92 completed the antimicrobial schedule. Comparison of patients receiving SAT (37) and LAT (55) showed that the SAT group had a shorter length of hospital stay (29 vs. 40 days, p 0.01), and a trend towards lower frequency of renal failure (5.4% vs. 18.2%, p 0.11) and hepatic failure (5.4% vs. 9.1%, p 0.69), whereas mortality (5.4% vs. 3.6%, p 1), relapse (0% vs. 1.8%, p 1) and re-infection (5.4% vs. 3.6%, p 1) rates were similar between both groups. Multivariate analysis showed that IE caused by Streptococcus viridans or Streptococcus bovis was independently associated with SAT. Postsurgical SAT is safe, especially when IE is caused by Streptococcus viridans or Streptococcus bovis, even in patients at high risk of complications.
