OBJETIVO: Evaluar calidad e índice de pseudoartrosis en la formación del callo óseo en artrodesis instrumentadas lumbares posteriores con injerto óseo autólogo enriquecido con factores de crecimiento plaquetarios (FCP). MÉTODOS: Estudio clínico analítico experimental simple ciego entre Junio de 2007 y Junio de 2009 comparando dos grupos, uno en el que se utilizó FCP en artrodesis lumbares posteriores y otro en el que no se aplicó el factor, evaluando las siguientes variables: índice de pseudoartrosis, formación del callo óseo y complicaciones postoperatorias. RESULTADOS: Se evaluaron 26 pacientes, edad promedio 61,23 años, divididos en dos grupos de 13 pacientes. El grupo en el que se utilizó FCP presentó fusiones radiográficamente sólidas en el 61,54 %, sin registro de pseudoartrosis pero con incidencia de infección y sangrado postoperatorios de 15.39%, mientras que en el grupo sin FCP el 69.23% alcanzó fusiones sólidas con 7.69% de pseudoartrosis sin otras complicaciones relacionadas con la intervención. CONCLUSIÓN: Si bien el grupo con FCP no presentó pseudoartrosis, registró mayor incidencia de complicaciones postoperatorias y menor número de fusiones radiográficamente sólidas. Aunque la cantidad de pacientes no permite obtener resultados estadísticamente significativos el presente puede ser el inicio de un estudio mayor.
OBJETIVO: Avaliar a qualidade e taxa de pseudoartrose em formação de calos em instrumentado fusão lombar com enxerto ósseo autólogo depois enriquecido com fatores de crescimento plaquetário (FCP). MÉTODOS: Analytical experimental tipo cego única clínica entre junho de 2007 e junho de 2009 comparando dois grupos, um que foi usado no FCP após artrodese lombar e outro que não se aplicam, avaliar as seguintes variáveis : taxa de pseudoartrose de formação de calos e as complicações pós-operatórias. RESULTADOS: Foram avaliados 26 pacientes, com idade média de 61,23 anos, divididos em dois grupos de 13 pacientes. O grupo que foi usado FCP apresentou fusões radiograficamente sólidos em 61,54%, sem registro, mas com incidência não-união de infecção e sangramento pós-operatório 15,39%, enquanto que no grupo sem o FCP% 69,23 alcançado fusões sólidas com 7,69% de pseudoartrose sem outras complicações relacionadas com a intervenção. CONCLUSÃO: Apesar de o grupo não se apresentar com FCP não sindicalizados, maior incidência de complicações pós-operatórias e menos fusões radiograficamente sólidos. Embora o número de pacientes que não é possível obter resultados estatisticamente significativos isso pode ser o início de um estudo maior.
OBJECTIVE: To evaluate quality and rate of pseudoarthrosis in callus formation in instrumented posterolateral lumbar fusion with the use of autologous bone graft enriched with platelet growth factors (PGFs). METHODS: A clinical analytical experimental single blind trial was carried out between June 2007 and June 2009 comparing two groups, one in which PGFs were used in lumbar spinal fusions while in the other the PGFs were not applied, to analyze the following variables: rate of pseudoarthrosis, callus formation and postoperative complications. RESULTS: We evaluated 26 patients, mean age 61.23 years, divided in two groups of 13 patients each. The group in which PGFs were used presented radiographically solid fusions at 61.54% with no record of pseudoarthrosis, although with incidence of infection and postoperative bleeding of 15.39%, while in the group without PGFs 69.23% achieved solid fusions presenting a rate of pseudoarthrosis of 7.69% with no other complications related to the intervention. CONCLUSION: Even though the group without PGFs did not present pseudoarthrosis, a higher incidence of postoperative complications and fewer radiographically solid fusions could be observed. Even though the number of patients is not sufficient to obtain statistically significant results, the present analysis may be the beginning of further study.

ABSTRACT
Nearly 230 species of biting midges have been recorded or described from Argentina; 38 of them are known from the Buenos Aires province and only one is cited from Martín García Island. This paper presents the results raised from six collecting trips which took place on the island during spring 2005, summer 2006 and autumn 2009. Diverse sampling sites including permanent and temporary aquatic environments were chosen, most of the ten sampling sites were ponds of diverse origin, some of these environments were covered with floating vegetation as Lemna gibba, Lemna minuscule, Salvinia biloba, Salvinia minima, Azolla filiculoides, Limnobium laevigatum, Pistia stratiotes, Spirodela intermedia, Wolffiella oblonga and Wolffia columbiana. Other sites were placed in urban and suburban areas. Adults were collected with sweep nets at sunrise and sunset and with light traps at intervals of four to five hours at night, depending on electricity availability on the island. Larvae and pupae were collected with different implements depending on characteristics of each surveyed aquatic habitat. In free standing water, they were captured with small sieves or hand pipettes and micropipettes, flotation techniques were utilized for sampling vegetated areas, free and rooted floating hydrophytes were extracted for removing insects among them. Thirteen species of Ceratopogonidae were collected, three of Atrichopogon Kieffer, three of Forcipomyia Meigen, two of Dasyhelea Kieffer, four of Culicoides Latreille, and one of Bezzia Kieffer, all representing new records from the island.

Alrededor de 230 especies de ceratopogónidos han sido registradas o descritas en Argentina, 38 de ellas son conocidas para la provincia de Buenos Aires y sólo una ha sido previamente citada para la Isla Martín García. En este trabajo se presentan los resultados obtenidos a partir de muestreos realizados en seis viajes a la isla durante la primavera de 2005, verano de 2006 y otoño de 2009; se seleccionaron diez sitios de muestreo con ambientes acuáticos permanentes y temporales. La mayoría de los muestreos se llevaron a cabo en cuerpos de agua de diverso origen; algunos de éstos se hallaban cubiertos con vegetación flotante compuesta por Lemna gibba, Lemna minuscule, Salvinia biloba, Salvinia minima, Azolla filiculoides, Limnobium laevigatum, Pistia stratiotes, Spirodela intermedia, Wolffiella oblonga y Wolffia columbiana; mientras que los restantes se realizaron en zonas urbanas y suburbanas. Los adultos se capturaron con redes entomológicas a la salida y puesta del sol y con trampas de luz a intervalos de cuatro a cinco horas por la noche, dependiendo de la disponibilidad de electricidad en la isla. Las larvas y pupas fueron recolectadas con diferentes metodologías según las características de los ambientes estudiados; en el agua libre se capturaron con tamices pequeños o pipetas y micropipetas, y en cuerpos de agua con vegetación se utilizó la técnica de flotación para separar los insectos de las hidrófitas flotantes y arraigadas. Se identificaron trece especies de Ceratopogonidae, 3 de Atrichopogon Kieffer, 3 de Forcipomyia Meigen, 2 de Dasyhelea Kieffer, 4 de Culicoides Latreille, y uno de Bezzia Kieffer, todos ellos representan nuevos registros para la isla.

Los quistes sinoviales lumbares constituyen una causa poco comun de lumbalgia o dolor radicular. En nuestro servicio fueron intervenidos quirurgicamente por el mismo cirujano 21 pacientes (13 mujeres y 7 varones) y en uno los sintomas remitieron luego del tratamiento conservador. Tanto la localizacion mas frecuente (L4-L5) como la predominancia del sexo femenino fueron coincidentes con las descritas en la bibliografia. La indicacion quirurgica se realizo ante el fracaso del tratamiento medico para la remision de la sintomatologia. Los pacientes fueron estudiados con radiografias, tomografia computarizada y resonancia magnetica, la cual consideramos el metodo de eleccion en estos casos. En 18 pacientes el diagnostico fue preoperatorio. En 2, el diagnostico preoperatorio fue sindrome del receso lateral siendo el quiste un hallazgo intraoperatorio. El tratamiento quirurgico consistio en la reseccion del quiste. En un paciente se realizo artrodesis debido a la coexistencia de espondilolistesis degenerativa en el mismo nivel. La planificacion quirurgica es fundamental, ya que la reseccion parcial de las facetas articulares necesaria para resecar el quiste puede incrementar la inestabilidad en ese espacio

Objetivos: evaluar los resultados obtenidos en pacientes con radiculopatía cervical espondilótica o discal operados mediante abordaje cervical posterolateral. Métodos: desde octubre de 1994 a enero de 1998, 30 pacientes consecutivos fueron intervenidos quirúrgicamente mediante foraminotomía posterior por cuadros de radiculopatía cervical. Hubo 23 hombres y 7 mujeres, con un promedio de 41 años. El seguimiento promedio fue de 64 semanas. Los resultados fueron analizados mediante los criterios de Odom y la escala semi-análoga. Resultados: al seguimiento el 90 por ciento de los pacientes tuvieron recuperación completa o habían mejorado considerablemente su condición prequirúrgica. Conclusión: usando estrictos criterios de selección, el abordaje posterolateral permite obtener excelentes resultados en la radiculopatía cervical espondilótica o discal, con escasa morbilidad
