Are complications after repairing acute Achilles tendon ruptures related to the surgical approach or the patient’s comorbidities?*
Objective: Analyze the postoperative complications after repairing acute Achilles tendon rupture and compare them according to the surgical approach (open surgery (OS) or minimally invasive surgery (MIS)) and the patient’s comorbidities.
Methods: A retrospective analytical study including 154 consecutive patients with an acute Achilles tendon rupture submitted to surgery and divided into OS and MIS cohorts. The following relevant comorbidities were analyzed: obesity, diabetes mellitus, smoking, dyslipidemia, gout, chronic corticosteroid use, connective tissue pathologies, transplant history, cancer treatment patients, and postoperative complications.
Results: Seventy-eight patients (50.6%) were treated surgically with an OS technique and 76 (49.4%) with an MIS approach. Twenty patients (13%) had postoperative complications between the two cohorts (OS 11.5%; MIS 14.5%; p = 0.588). No statistically significant difference was found in the logistic regression of the risk of the surgical approaches and complications. Obesity had a significant statistical difference when complications and comorbidities were compared.
Conclusions: Patients with obesity have a higher risk of developing postoperative complications with both OS and MIS techniques. No relationship was found between the type of surgical approach and a higher percentage of postoperative complications in treating acute Achilles tendon rupture
Incidencia de dedo flotante en la osteotomía metatarsiana distal percutánea con osteosíntesis para el tratamiento de la metatarsalgia con dedo en martillo rígido
Introducción: La metatarsalgia central es una causa frecuente de dolor de antepié. La osteotomía de Weil es el tratamiento quirúrgico más popular y la osteotomía metatarsiana distal percutánea (OMDP) es la técnica percutánea más utilizada. La principal desventaja de estas técnicas es la aparición de dedo flotante que es aún mayor cuando se la asocia a artrodesis interfalángica proximal (AIFP). En esta serie de casos, se combinó la OMDP y la osteosíntesis con clavija de Kirschner para elevar el centro de rotación de la cabeza del metatarsiano con el objetivo de disminuir la presencia de dedos flotantes. Nuestra principal hipótesis fue que esta técnica generará menos dedos flotantes en los pacientes con diagnóstico de metatarsalgia mecánica y dedo en martillo rígido, comparada con la osteotomía de Weil.
Materiales y Métodos: Se realizó un estudio retrospectivo en pacientes adultos con diagnóstico de metatarsalgia mecánica y dedo en martillo rígido. Se los sometió a una OMDP más fijación con clavija de Kirschner en combinación con AIFP. Finalmente, se comparó la presencia de dedos flotantes con un grupo de pacientes operados con la técnica de Weil y AIFP.
Resultados: Se realizaron 39 OMDP más AIFP. La tasa de dedos flotantes fue del 31%. No hubo una diferencia estadísticamente significativa comparada con la técnica de Weil (36%, p = 0,634).
Conclusión: La OMDP con elevación del centro de rotación asociada con AIFP no proporcionó una menor incidencia de dedos flotantes en comparación con la osteotomía de Weil
Endoscopic Calcaneoplasty in Haglund's Disease: Surgical Technique, Clinical and Subjective Outcomes
Category: Arthroscopy; Ankle Introduction/Purpose: During the last decade, arthroscopic procedures have been replacing open techniques in Haglund's disease treatment due to their considerable advantages. Endoscopic calcaneoplasty is a technique that allows resection of posterosuperior calcaneal exostosis and retrocalcaneal bursitis. The objective of this article is to describe this technique and report its clinical and subjective outcome. Methods: A retrospective cohort study was carried out in patients who underwent endoscopic surgery between July 2014 and March 2020. The patients were clinically and radiologically evaluated. All cases included were studied prior to the intervention and postoperative. All patients who did not show any clinical improvement after 6 months of conservative treatment were surgically treated with endoscopic treatment in the prone position through two posterior arthroscopic portals. Results: In this study, 14 endoscopic calcaneoplasties were performed in 14 patients, with an average follow-up of 40 months. The visual analog scale improved from a preoperative average value of 9.07 to 1.79 after surgery (p> 0.0001). The AOFAS scale rose from 38.71 before surgery to 94.57 postoperative (p> 0.0001). Good subjective results were observed in twelve patients ( 85.71%) and all of them would have surgery again. There were no wound complications or infections. No patient required reoperation. Conclusion: Endoscopic treatment is a useful technique, with good clinical and subjective results and few complications, being a good alternative to open techniques
Osteotomías supramaleolares en pacientes con artrosis de tobillo: resultados clínicos y radiográficos
Introducción: Las osteotomías supramaleolares son una opción terapéutica para la artrosis asimétrica de tobillo. El objetivo de este artículo es describir los resultados clínicos, radiográficos y subjetivos obtenidos en pacientes con artrosis de tobillo sometidos a una osteotomía supramaleolar.
Materiales y Métodos: Estudio observacional descriptivo retrospectivo de pacientes sometidos a una osteotomía supramaleolar por artrosis de tobillo entre enero de 2010 y julio de 2017. Se analizaron las historias clínicas para recabar datos clínicos y radiográficos preoperatorios y posoperatorios.
Resultados: Se incluyó a 13 pacientes: 8 con una desalineación del tobillo y retropié en valgo (61,5%) y 5 (38,5%) en varo. El puntaje medio posoperatorio de la escala analógica visual del grupo con deformidad en varo disminuyó de 9 ± 0,45 a 3 ± 1 (p <0,05) y de una media de 7,88 ± 0,35 a 2,15 ± 1,64 (p <0,05) en aquellos con deformidad en valgo. El puntaje medio de la escala de la AOFAS se modificó de 32,8 ± 16,2 antes de la cirugía a 82,1 ± 13,6 en el posoperatorio, en el grupo con deformidad en varo (p <0,05) y de 31 ± 17,3 a 93,1 ± 6,20, respectivamente, en aquellos con deformidad en valgo (p <0,05). Se constató la consolidación radiográfica en 12 pacientes (92,3%), en un promedio de 10.4 semanas.
Conclusión: La osteotomía supramaleolar como tratamiento de la artrosis asimétrica de tobillo es una técnica predecible, con muy buenos resultados clínicos y radiográficos a corto y mediano plazo
Inmunodeficiencias primarias: inmunopatogenia, infecciones asociadas y estrategias terapéuticas
Las inmunodeficiencias primarias (IDP) son un grupo de defectos genéticos que generan alteración en los mecanismos de defensa tanto innatos como adaptativos, asociados con: 1) ausencia de uno o varios de los componentes celulares, 2) incapacidad para la comunicación de los elementos de la respuesta inmune, así como también en el reconocimiento de antígenos extraños, propios o modificados e 3) incapacidad para la activación de los mecanismos efectores, bien sea por dificultad para alcanzar los tejidos afectados; para promover la polarización de la respuesta inmune tanto proinflamatoria como reguladora; o para liberar mediadores encargados de la destrucción de los agentes invasores. Este complejo grupo de enfermedades condicionan no solo a una susceptibilidad elevada para sufrir infecciones por diferentes agentes infecciosos, sino también a la alteración de los mecanismos homeostáticos y de vigilancia que evitan el desarrollo de enfermedades autoinflamatorias y neoplásicas. En esta revisión se describen parte de estos defectos, sus consecuencias y el abordaje inicial para el estudio y manejo de las infecciones recurrentes.
Primary immunodeficiencies: immunopathogenesis, associated infections and therapeutic strategies
Abstract
Primary immunodeficiencies disorders (PID) are a group of genetic defects that affect both innate and adaptive immune response. PID are associated with: 1) absence of cellular components, 2) impaired connection among components of the immune response, as well as in the recognition of foreign, self or modified antigens, and 3) inappropriate modulation of effectors mechanisms either by inability to reach affected tissues, to promote proinflammatory and regulatory polarization, or perform the clearance of invading agents. PID not only increases the susceptibility to infections by different microorganisms, but also alters the homeostatic mechanisms and immune surveillance, that prevent autoinflammatory and neoplastic diseases. This review describes some of these defects, its consequences and the initial approach to the study and management of recurrent infections
Empagliflozin in Patients with Chronic Kidney Disease
Background The effects of empagliflozin in patients with chronic kidney disease who are at risk for disease progression are not well understood. The EMPA-KIDNEY trial was designed to assess the effects of treatment with empagliflozin in a broad range of such patients. Methods We enrolled patients with chronic kidney disease who had an estimated glomerular filtration rate (eGFR) of at least 20 but less than 45 ml per minute per 1.73 m(2) of body-surface area, or who had an eGFR of at least 45 but less than 90 ml per minute per 1.73 m(2) with a urinary albumin-to-creatinine ratio (with albumin measured in milligrams and creatinine measured in grams) of at least 200. Patients were randomly assigned to receive empagliflozin (10 mg once daily) or matching placebo. The primary outcome was a composite of progression of kidney disease (defined as end-stage kidney disease, a sustained decrease in eGFR to < 10 ml per minute per 1.73 m(2), a sustained decrease in eGFR of & GE;40% from baseline, or death from renal causes) or death from cardiovascular causes. Results A total of 6609 patients underwent randomization. During a median of 2.0 years of follow-up, progression of kidney disease or death from cardiovascular causes occurred in 432 of 3304 patients (13.1%) in the empagliflozin group and in 558 of 3305 patients (16.9%) in the placebo group (hazard ratio, 0.72; 95% confidence interval [CI], 0.64 to 0.82; P < 0.001). Results were consistent among patients with or without diabetes and across subgroups defined according to eGFR ranges. The rate of hospitalization from any cause was lower in the empagliflozin group than in the placebo group (hazard ratio, 0.86; 95% CI, 0.78 to 0.95; P=0.003), but there were no significant between-group differences with respect to the composite outcome of hospitalization for heart failure or death from cardiovascular causes (which occurred in 4.0% in the empagliflozin group and 4.6% in the placebo group) or death from any cause (in 4.5% and 5.1%, respectively). The rates of serious adverse events were similar in the two groups. Conclusions Among a wide range of patients with chronic kidney disease who were at risk for disease progression, empagliflozin therapy led to a lower risk of progression of kidney disease or death from cardiovascular causes than placebo
