Objetivo: Evaluar los resultados estéticos y funcionales, así como el grado de satisfacción, posteriores a la reconstrucción de defectos de la extremidad inferior en niños con colgajo de dorsal ancho preservador del músculo como una alternativa para estos casos., Método: Se incluyeron pacientes menores de 18 años con defectos en la extremidad inferior tratados en un periodo de 3 años. Se realizó colgajo dorsal ancho preservador de músculo en todos los pacientes. Se valoraron la apariencia estética, la fuerza muscular del área donadora y la función en el área receptora a los 3 meses de realizado el colgajo., Resultados: Se realizaron 13 colgajos de dorsal ancho preservadores de músculo. La apariencia estética de las áreas donadora y receptora fue satisfactoria en la mayoría de los casos. La mayoría de los pacientes presentaron una fuerza muscular normal (M5) en el sitio donador y pudieron deambular., Conclusiones: El colgajo de dorsal ancho preservador de músculo tiene un grado de satisfacción muy elevado, excelente simetría y preservación de la función muscular del sitio donador. Es una técnica ideal en defectos tisulares importantes de la extremidad inferior en la población pediátrica., Objective: To evaluate the aesthetic and functional outcomes as well as the degree of postoperative satisfaction of the lower limb’s defects reconstruction with a muscle-sparing latissimus dorsi flap in children in order to propose this kind of reconstruction as a secure alternative., Method: In this study were included patients under 18 years with lower limb’s defects treated over a period of 3 years. A muscle-sparing latissimus dorsi flaps was performed in all patients. After three months the flap was performed, it was evaluated the donor’s area muscular strength, recipient area function and aesthetic appearance., Results: They were made 13 muscle-sparing latissimus dorsi flaps. In most cases, the donor and recipient area has satisfactory aesthetic appearance, most of the patients had a normal muscular strength (M5) in donors area and were able to walk., Conclusions: The reconstruction using a muscle-sparing latissimus dorsi flap has a very high level of satisfaction, excellent symmetry, and preservation of donor area muscle function. It is an ideal technique for major tissue defects of lower limb in children., (Copyright: © 2021 Permanyer.)

Objetivo: Evaluar el efecto de la refrigeración en la apoptosis y la viabilidad del lipoaspirado en las primeras 2 horas después de la toma., Método: Se incluyeron 20 pacientes que fueron sometidas a una liposucción del abdomen por razones estéticas. Se obtuvieron 5 ml de grasa y se procesaron para su estudio. La viabilidad se determinó usando azul tripano. La apoptosis se determinó usando el ensayo TUNEL., Resultados: Todas las pacientes eran mujeres, con una edad media de 36.5 años (rango: 21-67). Con respecto a la viabilidad, en el tiempo 0, en el grupo control fue del 59.08 ± 24% y en el grupo de refrigeración fue del 60.96 ± 22%; a los 60 minutos, los valores fueron del 50.82 ± 21% y el 55 ± 32.6%, respectivamente (p = 0.74); y a los 120 minutos, fueron del 42.69 ± 20.85% y el 50.33 ± 21%, respectivamente. En cuanto a la apoptosis, el porcentaje de células apoptóticas en el tiempo 0 fue del 37.87 ± 9.7% para el grupo de control y del 34.28 ± 9.74% para las muestras refrigeradas; a los 60 minutos, del 51.11 ± 8.64% y el 45.94 ± 9.15%, respectivamente; y a los 120 minutos, del 62.97 ± 13.33% y el 55.81 ± 9.45%, respectivamente., Conclusiones: Refrigerar el lipoaspirado a 4 °C disminuyó la mortalidad y la apoptosis de los adipocitos en menos del 10% en las primeras 2 horas desde la toma., (Copyright: © 2019 Permanyer.)

Objective: Migraine affects more than 35 million people in the United States of America, and 10% of the population in the world. The purpose of this study was to evaluate the effectiveness of surgical treatment in chronic migraine with frontal or occipital trigger areas., Methods: We designed a pilot, proof of concept, and prospective study to analyze the effectiveness of surgical release of trigger nerves in severe frontal or occipital chronic migraines. The study was approved by the Ethics and Investigation Committee of Hospital Universitario Dr. José Eleuterio González (Monterrey, N.L., Mexico). We included patients diagnosed with chronic migraine by the neurology service of Hospital Universitario Dr. José Eleuterio González that attended our consult from March to December 2012. The patients were assessed by the MIDAS questionnaire and the diagnosis confirmed by injecting 2% lidocaine in the trigger sites. We realized a superior palpebral approach in frontal migraines to resection the glabellar muscles and an occipital approach to free the greater occipital nerve bilaterally. We evaluated complete and partial clinical response measuring the frequency, intensity, and duration of migraine episodes., Results: We included three patients with Stage IV (severe incapacitating) frontal or occipital chronic migraines. Two were occipital trigger sites and one frontal. We obtained complete clinical response in two patients and a partial response in one. Pain intensity decreased in all patients., Conclusion: Surgical treatment is effective in Stage IV (severe incapacitating) frontal or occipital trigger chronic migraines., (Copyright: © 2019 Permanyer.)
