The role of Epstein Barr virus (EBV) in the onset of Hodgkin's lymphoma has been a subject of ongoing research. However, confirmation of EBV oncogenic involvement was not possible due to the small number of neoplastic cells characteristic for this type of tumor. Presence of EBV infection in neoplastic and non-neoplastic cells was analyzed in 81 cases of Hodgkin's lymphoma. In neoplastic cells, using an immunohistochemical method, latent membrane protein 1 (LMP1) was found in 33,3% of cases, while in situ hybridization results demonstrated the presence of EBER RNA in 48,1% of the cases. EBER RNA was found in non-neoplastic lymphocytes in 38,3% of cases. EBV is most frequently associated with Hodgkin's lymphoma in the first and seventh decade of life, specifically the nodular sclerosis subtype. No apparent difference was observed in the association of Hodgkin's lymphoma with EBV between genders, or in relation to clinical stage of the disease and average age of the patient. However, association with childhood age is significantly greater in comparison to adults. EBV associated disease shows a significantly greater prevalence in T lymphocytes. Slightly more abundant are cytotoxic T lymphocytes, which are also more frequently in contact with Reed-Sternberg cells, although there is no difference in number and positioning of histiocytes. Variations between the data on the association of EBV with Hodgkin's lymphoma among studies from different parts of the world suggest that factors of age, gender, ethnic background and social status might present biological modifiers of EBV influence on the pathogenesis of this neoplasm. The differences in non-neoplastic infiltrate EBV+ and EBV- lymphoma indicate the effect of the virus on the immune interaction of tumor and host in this disease.

UNLABELLED Low grade squamous intraepithelial lesion (LGSIL) and atypical squamous cells undetermined significance (ASCUS) are the most frequent verified cellular abnormalities. Their management are still highly controversial mostly caused by uncertainty about their histology and nature of originate. Detection of HPV DNA in the absence of cytological abnormalities can also indicate presence of high-grade cervical intraepithelial neoplasia (CIN). The aim of this study was to show the association of the benign cellular changes, ASCUS and LGSIL with oncogenic types of HPV and to prove the necessity of more intensive screening of this group of patients. Cytology and pathomorphology analyses were performed first. Identification of the presence of human papiloma virus was carried out by the Digene Hybride Capture II test for all patients. Identification of different HPV types for the particular number of patients was carried out by RFLP (Rsetriction Fragments Length of Polymorphism). Out of the 101 patients in the first group 92 (91,08%) were HPV positive, and 41, 58% had no cellular abnormalities, ASCUS or LGSIL. Out of 509 patients of the second group 26.92% were positive for HRHPV, and 78,97% of them had no cellular abnormalities, ASCUS or LGSIL. HPV 16 was detected in 27.36% (ASCUS/LGSIL) of low risk cervical lesion of the first examined period. CONCLUSION The combination of smears with the detection of high risk HPV types increases the triage sensitivity especially at patients with mild.

Gastritis can be defined in the simplest way such as inflammation of gastric mucous membrane. There are numerous causes of gastritis and the most often is Helicobacter pylori infection. Studying of the blood groups also includes the question of their connection with certain diseases. Up to date it has been explained the role that blood groups have in haemolytic disease of newborn infant but for other diseases we know little, it is insufficient or we know nothing. The aim of this work was to analyze connection of chronic gastritis in childhood, Helicobacter pylori and ABO blood groups. It has been treated 68 patients out of which 57 (83%) were Helicobacter pylori positive (Hp+) and 11 (17%) were Helicobacter pylori negative (Hp-). Thirty patients had chronic gastritis out of which 22 (73%) were Hp+ and 8 (27%) Hp-. It prevailed blood group A and O, comparing with other blood group phenotypes connected with gastritis.
