ABSTRACT
Trichinella spp. from a sylvatic cycle has been found in several animal species such as pumas (Puma concolor), armadillos (Chaetophractus villosus), rats (Rattus norvegicus), and wild boars (Sus scrofa) in Argentina. Moreover, Trichinella infection has been detected in a wide range of marine mammals around the world, including polar bears (Ursus maritimus) and walruses (Odobenus rosmarus). Until the present time, Trichinella spp. infection has not been detected in marine mammals of South America. Samples from four South American sea lions (Otaria flavescens) found dead in Rio Negro, Argentina, were analyzed by artificial digestion, and in the case of one animal, Trichinella larvae were identified at the species level by nested multiplex PCR as Trichinella spiralis. This is the first report of a Trichinella species infecting marine mammals from South America.

Ocho pacientes que sufrian aracnoiditis optoquiasmatica secundaria a meningitis tuberculosa fueron sometidos a cirugia en el departamento de Neurocirugia del Centro medico La Raza, del IMSS de 1976 a 1979.En todos los casos existia amaurosis en el examen preoperatorio y tuvieron recuperacion visual ad integrum desde el postoperatorio inmediato. Se enfatiza la importancia de tratamiento microquirurgico de estas lesiones, debido a que gracias a este y en combinacion con el tratamiento farmacologico se logro la curacion de estos enfermos, antes catalogados como incurables
