Where are we with Polish pathology at the turn of the centuries in the light of the Congresses of the Polish Society of Pathologists?

The aim of this study is to depict the current and past research directions in Polish pathology at the turn of the centuries. The analysis was based on the abstracts of the congresses of the Polish Society of Pathologists organized in 1992-2016 and concerned 1,824 presentations. It has been proven that oncology (1,090 presentations, 59.76%) was the most commonly discussed topic and dominated the dispute. Organ pathology was the area of research covered with over » of all papers (464 presentations, 25.44%), while subsequent topics played a marginal role: varia (86 presentations, 4.71%), infectious and parasitic diseases (84 presentations, 4.61%) and toxicopathology (56 presentations, 3.07%). A special, multidisciplinary category of veterinary pathology was particularized (44 presentations, 2.41%). Positive trend was revealed for oncology, while a downward one for the organ pathology, toxicopathology as well as pathology of infectious and parasitic diseases.

Research Directions in European Veterinary Pathology in 2010-2016 based on the Congresses of the European Society of Veterinary Pathology and the European College of Veterinary Pathologists.

The objective of this paper is to depict the current research directions in veterinary pathology in Europe. The analysis was carried out based on the abstracts and agendas of the annual European Society of Veterinary Pathology (ESVP) congresses organised together with the European College of Veterinary Pathologists (ECVP) in 2010-2016. In total, 1444 presentations were evaluated, including 41 plenary lectures, 319 short oral presentations, and 1081 posters, and in 2016 also three science slams. It was found that infectious and parasitic diseases (467 presentations, 32.34%) and oncology (450 presentations, 31.16%) were the most commonly discussed topics. Organ pathology was also addressed (327 presentations, 22.65%), with the subsequent places taken by research on different topics (140 presentations, 9.70%) and toxicopathology (67 presentations, 4.64%). Among the most commonly presented issues, there was a substantial number of presentations on neurology (129 speeches, 8.93%) and mammary gland diseases (101 presentations, 6.99%). A downward trend was revealed for infectious and parasitic diseases and for oncology, and a positive trend for organ pathology, the first and the third being statistically significant.

Head arteries of the red squirrel (Sciurus vulgaris).

The red squirrel (Sciurus vulgaris) is a medium-sized rodent protected in most of Europe. The present study aimed to investigate and describe the arterial vascularization of the head of the adult red squirrel. In the study, 48 specimens of adult red squirrels were used. The first preparation method used in the study was corrosion casting using a stained solution of the chemo-setting acrylic material injected into bilateral common carotid arteries resulting in corrosion castings of the vessels on a bone scaffold. The second method was injecting liquid-stained latex into both common carotid arteries. It resulted in a stained arterial vessel on fixed soft tissue preparations. The main vessels providing blood to the head were paired with common carotid arteries that divide into external and internal carotid arteries. The internal carotid artery passes into the stapedial artery. After giving its branches, the stapedial artery exits the cranial cavity through the sphenofrontal foramen and enters the orbit. The suborbital and the mandibular regions were supplied by the maxillary artery, linguofacial trunk, and their branches. Description of the detailed anatomy of the head arteries in red squirrels may contribute to establishing diagnostic and treatment protocols for wildlife rehabilitation centers, which may be crucial since red squirrels are endangered by the spreading of invasive Eastern gray squirrels (Sciurus carolinensis) in Europe. It may also contribute to veterinary care for other members of the Sciuridae family kept as pets.

Invasive forms of canine endoparasites as a potential threat to public health - A review and own studies.

[b]Abstract [/b] Dogs serve as the vectors of serious zoonotic parasitic diseases. In the month of May 2012 - 2014, 339 dog faeces samples from seven public sites in Chelmno, a town in northern Poland, were collected and examined to determine the gastrointestinal parasite fauna of dogs. Each faecal sample was dissected with a needle, checked for tapeworm segments and examined for parasite eggs and oocysts using the flotation and decantation method and a modified Baermann technique. Differences were observed in the degree of parasite species occurrence. The most dominant were [i]Toxocara canis[/i] and Ancylostomatidae. The detected species included: [i]T. canis [/i]and [i]Toxascaris leonina[/i] eggs (23.4% and 10.2%, respectively), as well as eggs from the[i] Ancylostomatidae[/i] family (16.2%),[i] Trichuris vulpis [/i]eggs (6.6%), [i]Taenia[/i] type eggs (4.6%),[i] Dipylidium caninum[/i] (5.2%) and [i]Cystoisospora [/i](Isospora) spp. oocysts (10.9%).

Histopathology of liver and kidneys of wild living Mallards Anas platyrhynchos and Coots Fulica atra with considerable concentrations of lead and cadmium.

Concentrations of cadmium and lead were measured in liver and kidneys of Mallard (n=60) and Coot (n=50). Free living birds were collected by hunters in years 2006-2008 in the area of fishponds near Zator in southern Poland. Age group was determined according to the appearance of the plumage (Mallards) and iris color (Coot). Concentrations of metals were measured with ET-AA spectrometer. Among all birds specimens with negligible (n=5) and high concentrations (Mallards n=18 and Coots n=17) of cadmium and lead were chosen for further analysis. Histopathological alterations were observed, ranging from circulatory disturbances, retrogressive changes, inflammations to leukocytic infiltration in liver and kidney. They dominated among birds with the highest concentrations of metals. The control group of birds was characterized by a very small number of mentioned lesions. Probably the higher cadmium and lead concentrations in tissues are co-factors in the development of lesions.
