The study was performed on 45 patients with heart transplantation out of which 30 presented serologic cytomegalovirus infection. For histological study we used: hematoxylin eosin, van Gieson, Masson's trichrome, green methyl pironin stains. Immunohistochemistry was performed using ABC technique (avidin - biotin complexes or avidin - biotin) with the following monoclonal antibodies: CD8, CD4, CD20, CD68, CD31, CD45 RO, HLA-DR, and E13. In many of our cases cytomegalovirus infection was commonly associated with acute rejection. The presence of endothelial cells expressing HLA-DR antigens and subendothelial accumulation of activated T lymphocytes and macrophages, often in contact with endothelial cells, highlights the role of cellular immunity in the production of accelerated atherosclerosis lesions.

The etiological role of HPV infection in the pathogenesis of bladder tumors remains uncertain. Case-control study, NMIBC patients answered a 37 items questionnaire regarding knowledge of HPV, were compare with a healthy control group. Group A started earlier the sexual life than the group B (18 vs. 19 years), but the first cohabitation took place later (37 vs. 24 years, p = 0. 03).Group A had more sexual partners than group B (>10, 32% respectively 17.6%). 56% of patients with NMIBC heard about HPV infection and only 47% of controls and 32% of group A respectively 41% of group B didn't know if HPV infection represents a risk for their health. From this study results a lack of knowledge about HPV infection in NMIBC patients. [ABSTRACT FROM AUTHOR]

We will present the case study of a 61 years old Caucasian female patient who required a dermatological consult for two well defined painful ulcerations on her right leg, with overhanging borders, a geographical erythematous-purplish outline and a surface covered with adherent necrotic deposits. Ten years prior she was diagnosed with Sjögren's syndrome. After skin biopsy, pyoderma gangrenosum diagnostic was established, a rare finding in a Sjögren's syndrome patient. Systemic corticotherapy and chemical debridement of the lesions proved a successful treatment method. [ABSTRACT FROM AUTHOR]
