Tratamiento de punta nasal mestiza en rinoplastía secundaria / Treatment of mestize tip nose in secundary rhinoplasty

ANTECEDENTES: la nariz mestiza constituye un reto en la adecuada trasformación estética y funcional de la rinoplastia, más aún cuando esta se realiza en una segunda intervención y los tejidos nasales ya se encuentran alterados, no pudiendo hacer una adecuada reconstrucción de las estructuras anatómicas sin el uso de injertos cartilaginosos de otras áreas del cuerpo. OBJETIVO: el propósito de este trabajo es de evaluar los resultados obtenidos de una reconstrucción de la punta nasal, realizada en pacientes que ya fueron sometidos a una rinoplastia sea esta secundaria o cuaternaria. METODOLOGIA: estudio retrospectivo, de casos de pacientes que se sometieron a una nueva intervención para mejorar aspectos estéticos y funcionales nasales, que ya fueron operados en más de 1 oportunidad. HALLAZGOS: se tiene un universo de 10 pacientes en los que se realizó una rinoplastia secundaria o cuaternaria donde se utilizó injerto costal para conformar el esqueleto cartilaginoso y el uso de un injerto de extensión septal, todo esto para mejorar la estética y funcionalidad nasal.

Seaweeds: an opportunity for wealth and sustainable livelihood for coastal communities.

The European, Canadian, and Latin American seaweed industries rely on the sustainable harvesting of natural resources. As several countries wish to increase their activity, the harvest should be managed according to integrated and participatory governance regimes to ensure production within a long-term perspective. Development of regulations and directives enabling the sustainable exploitation of natural resources must therefore be brought to the national and international political agenda in order to ensure environmental, social, and economic values in the coastal areas around the world. In Europe, Portugal requires an appraisal of seaweed management plans while Norway and Canada have developed and implemented coastal management plans including well-established and sustainable exploitation of their natural seaweed resources. Whereas, in Latin America, different scenarios of seaweed exploitation can be observed; each country is however in need of long-term and ecosystem-based management plans to ensure that exploitation is sustainable. These plans are required particularly in Peru and Brazil, while Chile has succeeded in establishing a sustainable seaweed-harvesting plan for most of the economically important seaweeds. Furthermore, in both Europe and Latin America, seaweed aquaculture is at its infancy and development will have to overcome numerous challenges at different levels (i.e., technology, biology, policy). Thus, there is a need for regulations and establishment of "best practices" for seaweed harvesting, management, and cultivation. Trained human resources will also be required to provide information and education to the communities involved, to enable seaweed utilization to become a profitable business and provide better income opportunities to coastal communities.
