Nuevos registros de la familia Cucumariidae (Holothuroidea: Dendrochirotida) en el Pacifico mexicano / New records of the family Cucumariidae (Holothuroidea: Dendrochirotida) for the Mexican Pacific

Introducción: Los cucumáridos son un grupo cosmopolita de pepinos de mar que habitan en sedimentos rocosos-arenosos, desde la zona intermareal hasta la zona abisal. Objetivo: Presentar nuevos registros para el Pacífico mexicano. Métodos: Se utilizó estereoscopio y microscopía electrónica de barrido para mostrar la morfología externa e interna de especímenes de la colección de la Universidad Nacional Autónoma de México. Resultados: Presentamos una sinopsis taxonómica de cucumáridos en el Pacífico mexicano y revisamos su taxonomía en las espículas. Se confirma la identidad taxonómica de Pseudocnus curatus, Pseudocnus dubiosus y Pseudocnus lubricus y se descarta la presencia de Trachythyone peruana. Conclusiones: Se presentan cuatro nuevos registros para el Pacífico mexicano: Leptopentacta nina, Pseudocnus curatus, Pseudocnus dubiosus y Pseudocnus lubricus.

Introduction: Cucumarids are a cosmopolitan group of sea cucumbers that inhabit rocky-sandy sediments, from the intertidal zone to the hadal zone. Objective: To present new records for the Mexican Pacific. Methods: We applied stereoscope and scanning electron microscopy to external and internal morphology of specimens in the collection of the National Autonomous University, Mexico. Results: We present a taxonomic synopsis of cucumarids in the Mexican Pacific and review their taxonomy on the ossicles. The taxonomic identity of Pseudocnus curatus, Pseudocnus dubiosus and Pseudocnus lubricus is confirmed, and the presence of Trachythyone peruana is ruled out. Conclusions: Four new records are presented for the Mexican Pacific: Leptopentacta nina, Pseudocnus curatus, Pseudocnus dubiosus and Pseudocnus lubricus.

Recurrent epistaxis from a post-traumatic infraorbital artery pseudoaneurysm

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To present a rare case of post-traumatic recurrent epistaxis in an elderly woman.<br /><strong>METHODS:</strong><br />  <strong>Design:</strong> Case Report<br /> <strong> Setting:</strong> Tertiary Private Hospital<br /><strong>  Patient:</strong> One<br /><strong>RESULT:</strong> A  93-year-old  woman  had  multiple  admissions  for  recurrent  life  threatening  nose-bleeding  that  was  not  controlled  until  a  post-traumatic pseudoaneurysm  of  the  infraorbital artery was diagnosed and embolized.<br />CONCLUSION: The diagnosis of pseudoaneurysm should be considered in such cases, and treatment involving surgeons and interventional radiologists should be initiated to minimize morbidity and mortality.</p>
