ABSTRACT
We report a case of pancreatic pseudocyst in alcoholic pancreatitis, that presented as a mass in the inguinal region. The mechanism of this peculiar clinical presentation was the dissemination of the content of the pseudocyst along the psoas muscle. We review the involvement of psoas muscle in pancreatic pathology, giving emphasis to reports of inguinal or thigh masses as initial manifestations.

The infection caused by Listeria monocytogenes is a relatively common condition in immunosuppressed patients. The most frequent presentation in adults are sepsis and meningitis. Pleural fluid infection due to this pathogen is a rare finding in the literature. Most cases are found in immunosuppressed patients, particularly in those with haematologic malignancies. We report one case of pleural fluid infection due to Listeria monocytogenes in a patient with hepatic cirrhosis (the third case in the literature). We also review the seventeen cases previously reported and describe the clinical manifestations, its immunosuppression states relationship, the treatment of choice and the mortality.

The effect of intracoelomic tagging of an acoustic telemetry transmitter (1.65% ratio of tag mass in the air to fish mass in the air) on behavioral (food intake and locomotor activity) and physiological (blood glucose and plasma cortisol) parameters of gilthead seabream was investigated. To this end, fish (289 ± 53 g, mean ± SD) were divided into 3 experimental groups: control (C), transmitter (T, inserted surgically) and sham group (S, subjected to surgery but without transmitter insertion). Blood was extracted during surgery and 9 days later. Throughout the trial, fish were fed by means of self-feeders and locomotor activity was measured by means of an infrared photocell. Two days after the first manipulation, a significant decrease in food intake could be observed in all the experimental groups. The fact that food intake was not affected after the second manipulation seems to indicate that a learning process took place for handling. The rhythmicity of feeding and locomotor activity was not affected by handling in any experimental group. However, group T showed increased plasma cortisol levels 9 days after surgery. In conclusion, while most behavioral parameters were not affected by handling, the plasma cortisol levels of seabream 9 days after insertion of the transmitter indicated a physiological impact that should be taken into account in long-term radiotracking studies, since such an operation could have negative effects on wild individuals after the end of the tracking experiments.

La infección por Listeria monocytogenes es relativamente frecuente en pacientes inmunodeprimidos, la sepsis y la afectación neuromeníngea son las formas de presentación más habituales. La infección de la cavidad pleural por este germen es una entidad escasamente descrita en la literatura, en la mayoría de los casos se presenta en pacientes inmunodeprimidos, sobre todo con enfermedades hematológicas malignas. Presentamos un caso de infección pleural por Listeria monocytogenes en un paciente con cirrosis hepática (tercer caso descrito) y revisamos diecisiete casos previos analizando las formas de presentación, su relación con estados de inmunodepresión, tratamiento de elección y mortalidad (AU)
