Robot assisted laparoscopic excision of a paraganglioma: new therapeutic approach

The Paraganglioma is the most common extra-adrenal pheochromocytoma arising from neural crest (1) (It will better to write: The paraganglioma is an extra-adrenal pheocromocytoma arising from the neural crest. 10% of pheocromocytomas are extra-adrenal and can arise form chromaffin tissue derived from primitive neuroectoderm). Minimally invasive techniques allow surgeons to perform the procedure without wide exposure and mobilization of intra abdominal organs. To our knowledge we present the third case of robotic excision of a retroperitoneal paraganglioma (2,3).

Pandemic influenza A/H1N1 virus in a swine farm house in Sicily, Italy.

This report describes a pandemic A/H1N1 (H1N1 pdm) virus outbreak occurred in December, 2009 in a swine farm used as research facility (Istituto Mediterraneo Trapianti e Terapie ad Alta Specializzazione) for preclinical studies, located in Sicily, Italy. All the 13 pigs of the farm, showed cough, fever, inappetence and weakness. At the same time, an unvaccinated worker of the stabling showed influenza-like symptoms. RNAv extracted from two swabs collected from infected pigs resulted positive by Real Time RT-PCR for Influenza A virus. Furthermore, after growth on embryonated eggs, viral isolates were identified by Real Time RT-PCR specific for H1N1 pdm virus and characterized antigenically. Sequencing of the whole genome was also performed. All sera taken from animals and from the worker were tested by a competitive Influenza A ELISA and by the haemoagglutination inhibition test. Serological findings confirmed the circulation of influenza virus H1N1 pdm in pigs and the presence of specific antibodies against H1N1 pdm in human serum. The results of this study seem to support a H1N1 pdm transmission from man to animals showing the importance of serological and virological investigation to control the pig farms and the importance of close cooperation between the different authorities like veterinarian and human public.

Ocorrência de Hepatozoon spp. (Apicomplexa, Hepatozoidae) em serpentes do gênero Bothrops de cativeiro / Occurrence of Hepatozoon spp. (Apicomplexa, Hepatozoidae) in snakes of genus Bothrops in captivity

The occurrence of Hepatozoon gamont in the blood cells of Bothrops jararaca and B. jararacussu in captivity was analyzed. The prevalence of infection by Hepatozoon spp. was 50 percent and few erythrocytes contained the gamonts. Results suggest that the infection by Hepatozoon spp. occurred in the natural environment or after the captivity.
