Autologous blood transfusion is a very effective method for reducing consumption of allogenic blood and thus, indirectly for reducing all complications related to allogenic blood transfusion. There is also a positive influence on postoperative recovery after total knee replacement surgery due to the reduction of hospital stay, and indirectly on the reduction of hospital costs.

Histological abnormalities of clinically normal-looking oral mucosa taken at different distances from the tumor lesion indicated the existence of subclinical field change and represent an important parameter during the assessment of the adequacy of surgical resection margins in oral cancer management.

NBI videobronchoscopy had better specificity and sensitivity in the assessment of tumor extension in centrally located lung cancer, and it might play a significant role in the therapeutic decision.

Ground waters in the region of Autonomous Province of Vojvodina, Republic of Serbia are endangered by arsenic (up to 0.750 mg/l). Total arsenic concentration was determined In samples of untreated and treated water from some local and central water-supply systems. Results are compared to actual regulations in the country. This analysis encompassed 324 drinking water samples of various sources, analyzed in the Institute of Public Health Novi Sad, during 2005. Determined concentration of total arsenic in drinking water varies from 0.005 to 0.450 mg/l. Arsenic concentration in the river Danube water was within recommended value for I-II class. Maximum arsenic daily intake through food and nutrition was 60.9± 22.3 μg/day in 2000. To understand importance of the problem of arsenic environment contamination in Vojvodina region, our own results, as well as the results of other authors are presented and analyzed (drinking water: 173 samples, moss deposition and daily intake through nutrition).

Background:The aim of the study was to determine the microbial presence and type in the biofilms present on the surface of oral squamous cell carcinomas and benign lesions of oral mucosa.Methods: Thirty new (untreated) patients with oral squamous cell carcinoma were examined. The control group consisted of thirty subjects with benign lesions of oral mucosa. Swab samples were taken from the superficial layer of the carcinoma and benign lesions for bacteriological examination. Swabs were transported within 2 hours and immediately sown and incubated. Oral health index was assessed in all patients. Results:The prevalence of pathological bacterial microflora was significantly higher in cancer patients (p<0.01). No significant associations were found between bacterial presence and gender, localization, cigarette smoking, alcohol consumption and denture wearing (p>0.05). Poor oral hygiene was also registered in cancer patients. Conclusion:Possibility of microflora retention on irregular oral carcinoma surface possibly contributes to chronic inflammation often observed on the surface of oral carcinomas.
