Helicobacter pylori and Epstein-Barr Virus Co-Infection in Polish Patients with Gastric Cancer - A Pilot Study.

The infectious agents may be the etiological factor of up to 15-20% of cancers. In stomach cancer, attention is paid to Helicobacter pylori and Epstein-Barr virus, both of which cause gastritis and can lead to tumor development. In co-infection, the inflammatory process is much more intense. We assessed the seroprevalence towards H. pylori and EBV in 32 patients with diagnosed gastric cancer. H. pylori antibodies were found in 69% patients, and anti-EBV - in all of them. The study confirmed that co-infection of H. pylori and EBV seems to be important in etiopathology of gastric cancer.

Management of hard-to-heal wounds arising as a result of surgical oncology treatment- usage of the modern wound dressings.

The problem of hard-to-heal wounds concerns 1-1.5% of the total population and about 3% of the population above 60 years of age. The risk factors associated with impaired wound healing are diabetes, arterial and venous insufficiency, advanced atherosclerosis, obesity, and inadequate wound supply. As a result of these pathological processes may develop localized wound infection, disseminated infection, tissue necrosis, and even chronic inflammation carcinogenesis. In the group of patients with malignant tumors, there are wounds arising in the course of the underlying disease and as a result of medical treatment. Wound healing is a significant problem and is often complicated due to the patient's general condition, comorbidities and complex treatment of cancer, which includes surgery, radiotherapy, and chemotherapy. Radiotherapy used for local-regional control of disease after surgical treatment has a negative effect on healing by causing fibrosis of tissues and blood vessels damage, while chemotherapy interferes with the process of cell proliferation.
