RESUMO
Papilloma and fibropapilloma cases are quite common in cattle breeding, which cause economic losses due to decrease in the production of milk, meat, and also impair the quality of hide. In this study, we aimed to determine viral etiology and investigate p53 expression levels with immunohistochemical methods from a total of 30 cases. The study material was collected between 2013 and 2021 in Kars, Turkey. Paraffin embedded tissues were used for earlier cases in which the freshly specimens could not be provided. Cases were investigated for papillomavirus etiology with polymerase chain reaction (PCR) using FAP59/FAP64 and MY09/MY11 primer pairs. In 20 of the 30 cases papillomaviruses were identified, and 10 cases were identified as Bovine papillomavirus-1 (BPV-1), 1 case as BPV-2, 1 case as BPV-12, and 1 case as equus caballus papillomavirus 2 (EcPV-2) after sequence analysis. p53 immunostaining was also performed, and the cases were graded according to the positively stained cells. In conclusion BPV-12 was detected for the first time in our country, EcPV-2 was detected first time in cattle indicating cross species infection and p53 was staining most evident in BPV-1 and BPV-2 cases and BPV-12 and EcPV-2 was not stained.

Coronary involvement in Behçet's disease is extremely rare and it can bring devastating consequences when it occurs. In this report, we present a 29-year-old male patient with Behçet's disease who developed rapidly changing and progressive coronary artery involvements under medical treatment.

BACKGROUND: Left atrial (LA) volume has been identified as a predictor of adverse cardiovascular outcomes, both in the general population and in selected clinical conditions. The aim of this study was to evaluate the effect of psoriasis on LA volume and mechanical function. METHODS: A total of 40 consecutive normotensive psoriasis patients free of any cardiovascular disease and 39 healthy volunteers were included. All participants underwent comprehensive transthoracic echocardiographic examination. LA volume and mechanical function were evaluated using real-time three-dimensional echocardiography (RT3DE). RESULTS: There were no significant differences between psoriasis and control groups with regard to conventional echocardiographic parameters. Individuals with psoriasis had a higher incidence of left ventricular diastolic dysfunction (LVDD) than the controls; nine people with psoriasis (23%) and three control individuals (8%) had LVDD (p = 0.06). With regard to the parameters obtained from RT3DE, LA maximum, LA minimum, passive stroke volume, and passive emptying fraction were significantly higher; whereas LA active emptying fraction, LA total emptying fraction, LA expansion index, and active stroke volume values were significantly lower in individuals with psoriasis compared with controls. Disease duration and Psoriasis Area of Severity Index (PASI) score correlated with the majority of volume parameters. CONCLUSION: Individuals with psoriasis had higher LA phasic volumes and impaired LA mechanical function compared with healthy controls. LA volume and functional analysis with RT3DE may facilitate recognition of subtle LA dysfunction in patients with psoriasis.
