Perkinsus chesapeaki observed in a new host, the European common edible cockle Cerastoderma edule, in the Spanish Mediterranean coast.

Histological observations showed the presence of a Perkinsus sp. parasite in Cerastoderma edule tissues for the first time in the Spanish Mediterranean coast. ITS molecular characterization by PCR-RFLP, in situ hybridization and sequencing, identified the parasite as Perkinsus chesapeaki, with a maximum identity of 99-100% with GenBank P. chesapeaki sequences from France and 97% with P. chesapeaki sequences of North American origin when BLAST analysis was carried out. Furthermore, phylogenetic studies placed the European cockle parasite in a well defined cluster together with the other European isolates. This is the first report of P. chesapeaki in the cockle C. edule.

Encefalitis y psicosis en la adolescencia: a propósito de un caso / Encephalitis and psychosis in adolescence: report of clinical case

La encefalitis por virus herpes simple es una infección del sistema nervioso central y constituye una emergencia médica por su elevada mortalidad y morbilidad, por lo que requiere una detección y tratamiento tempranos. Se presenta un caso de un adolescente de 16 años sin antecedentes somáticos ni psiquiátricos previos que debuta con un cuadro clínico de aparición brusca caracterizado por sintomatología psicótica productiva. Después de una evaluación exhaustiva se aísla el Virus de Herpes Simple tipo 1 (VHS-1) en líquido cefalorraquídeo (LCR), con buena respuesta al tratamiento con Aciclovir. Este caso ilustra la importancia de descartar las causas orgánicas en pacientes con un primer episodio psicótico y establecer un tratamiento precoz, lo cual va a condicionar el curso y el pronóstico de la enfermedad

Herpes simplex encephalitis is an infection of the central nervous system and is a medical emergency due to its high mortality and morbidity, which requires early detection and treatment. We present a case of a 16-year-old adolescent with no prior somatic and psychiatric history, who debuted with a sudden onset of clinical symptoms characterized by productive psychotic symptoms. After extensive workup, Herpes simplex virus type 1 (HSV1) is detected in cerebrospinal fluid (CSF), with good response to Acyclovir treatment. The case illustrates the importance of ruling out the organic causes in patients with a first psychotic episode and establishing early treatment, which is a determining factor in the course and prognosis of the disease
