RESUMO
La acupuntura es una terapéutica de la medicina tradicional china utilizada desde hace más de 3.000 años. Recientemente ha ido ganando popularidad entre pacientes y médicos en el mundo occidental. Investigaciones en ciencias básicas aclaran los mecanismos fisiológicos de la acupuntura. Múltiples investigaciones muestran que la acupuntura desencadena una respuesta neuroendocrina que activa cascadas de opioides endógenos. Numerosos estudios clínicos controlados y aleatorizados, y revisiones sistemáticas han intentado evaluar la eficacia clínica de la acupuntura. La evidencia derivada de estos trabajos avala la acupuntura como un tratamiento eficaz para el dolor dental, las náuseas y vómitos de los posoperatorios y de la quimioterapia. Para otras condiciones, los resultados todavía no son concluyentes dado que la investigación clínica en acupuntura plantea retos metodológicos que están en proceso de ser superados. La acupuntura es una terapéutica segura en manos entrenadas. La comunidad médica se está abriendo a la utilización de la acupuntura como una terapéutica no farmacológica complementaria a la práctica médica habitual. Son necesarios más estudios que nos permitan ir esclareciendo las dudas y que sirvan de puente entre este antiguo arte de curar y los sistemas modernos de salud (AU)
Acupuncture is an important therapy from traditional Chinese medicine that has been used for more than 3,000years. Recently, the popularity of this technique has been increasing among patients and physicians in Western countries. Basic-science research has clarified the physiological mechanisms of acupuncture. It has been shown in many investigations that acupuncture precipitates a neuroendocrine response that activates cascades of endogenous opiates. Numerous randomized, controlled trials and systematic reviews have evaluated the clinical efficacy of acupuncture. The evidence obtained from these works have demonstrated that acupuncture is an effective treatment for dental pain, postoperative nausea and vomiting and chemotherapy-related nausea and vomiting. Evidence is non-conclusive for other conditions since clinical research in acupuncture poses methodological challenges that must still be overcome. Acupuncture is relatively safe when performed by experts. Health care providers are changing their view on the use of acupunture as a non-drug treatment that is complementary to the conventional medical approach. More studies are needed in order to help us clarify the doubts and to serve as a link between this ancient healing art and modern medicine (AU)

Introducción: El uso de alcohol y otros antisépticos para la cura delcordón umbilical está ampliamente extendido. No hay unidad entre loscentros y profesionales sobre cuál es la mejor manera de realizar la curadel cordón umbilical.Objetivo: Revisar la evidencia científica disponible sobre la cura enseco del cordón umbilicalMetodología: Revisión bibliográfica a partir de bases de datos en españoly en inglés. Consulta de las páginas web de los organismos oficialesy asociaciones de profesionales de la salud.Conclusiones: No hay motivos para desaconsejar la cura en seco delcordón umbilical del recién nacido en nuestro medio (AU)

Objective: To compare the polymerization effectiveness of two resin composites cured with a quartz tungsten halogen(QTH) lamp or a light emitting diodes (LED) unit. Study design: Filtek Z250 (3M ESPE) and Spectrum TPH (DentsplyDeTrey) resin composites were placed in 9 mm deep and 4 mm wide metallic molds and cured using the QTH light Hilux200 (Benlioglu) or the LED unit Smartlite IQ (Dentsply DeTrey) for 20 or 40 s (three specimens per group). Measurementof depth of cure was carried out by means of a scraping technique, according to ISO 4049. The microhardness measurementswere performed using a calibrated Vickers indenter (100 g load, 30 s) at depths of 0.5, 1.5, 2.5, 3.5, 4.5 and 5.5 mm fromthe top of the composite in the same specimens. Results were analyzed by ANOVA, Student´s t and Student-Newman-Keulstests (p<0.05). Results: Filtek Z250 exhibited higher depth of cure and Vickers microhardness values than Spectrum TPHunder each experimental condition evaluated. Depth of cure and microhardness were not affected by the curing light used.However, hardness values were influenced by the interaction between curing light and exposure time. Specimens irradiatedfor 20 s exhibited higher microhardness values when the LED curing light was used. Exposure time had no influence on themicrohardness values for depths from 0.5 to 2.5 mm. At higher depths, irradiation for 40 s produced greater microhardnessvalues. Conclusions: Curing effectiveness of resin composite is not only dependent on the curing light unit. Results varygreatly with composite brand, thickness of the resin composite and the duration of the exposure (AU)
