Presentazione atipica di linfoma felino caratterizzata da infiltrazione atriale sinistra e pericardica associata a versamento pericardico e tamponamento cardiaco
No full textViene descritto il caso clinico di un gatto presentato con un quadro di shock ostruttivo. L’ecocardiografia mostrava grave versamento pericardico associato a tamponamento cardiaco, lieve versamento pleurico, soggettivo ispessimento del pericardio e ispessimento focale della parete laterale atriale sinistra. Il paziente veniva trattato mediante centesi dei versamenti cavitari; la loro valutazione citologica non mostrava segni di malignità (il quadro citologico risultava indicativo di un quadro infiammatorio non settico) e le relative colture risultavano negative. Nelle successive due settimane si assisteva alla recidiva del versamento pleurico. In quell’occasione l’ecocardiografia rilevava anche una neoformazione mediastinica circondante l’aorta ascendente. La valutazione citologica della neoformazione risultava diagnostica per un linfoma. A quel punto, i proprietari rifiutavano ulteriori indagini diagnostiche e optavano per l’eutanasia. La valutazione post-mortem attestava un linfoma mediastinico a grandi cellule B con infiltrazione secondaria del pericardio e dell’atrio sinistro. A conoscenza degli autori, tale tipo di infiltrazione cardiaca risulta atipica in quanto i linfomi cardiaci felini, sia quelli primari che secondari, tendono solitamente a infiltrare il ventricolo sinistro

Full text linkThe aim of the study is to describe the ultrasound (US) findings associated to canine leishmaniasis (CVL) in dogs from an endemic area.
Thirty-four dogs naturally infected by Leishmania Infantum were enrolled. Morphologic changes of abdominal parenchymatous organs, including size,
change in echogenicity and echo-texture and the presence of focal or diffused lesions were recorded. When possible the return to normal of US changes after
treatment were monitored, in order to further confirm the association with the disease.
The most common pathological findings were: spleen from mild to severely enlarged, hyperechogenicity of renal cortex and hepatomegaly. Interesting
findings were: the honey-comb splenic parenchymal pattern (2 dogs), the cirrhotic/fibrotic aspect of the liver (2 dogs) and the abdominal lymphadenopathy
in absence of peripheral lymphadenopathy (2 dogs). Focal macro nodular lesions in spleen and liver, as described in some human cases, were not registered.
Results of this study suggest the ultrasonography could contribute to define the systemic involvement of dogs with leishmaniasis and to monitor the response
to treatment. Canine leishmnaiasis need to be included in the differential diagnosis of the US honey-comb appearance of the spleen

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
