Abstract
The aim of this work was a comparative study of the effects of spring diseases cytogenetic years of tick-borne encephalitis in elderly and young age due to differences in genes of glutathione-S-transferase. Surveyed by routine cytogenetics 120 patients with tick-borne encephalitis residents North of Tomsk region. We have taken in the study persons aged 20-35 years (Group 1) and 65-85 years old (Group 2). Material for study (buccal epithelium) was taken from each subject 3-5 times: 1st-2nd day after hospitalization, in 1 week, 1, 3 and 6 months. Tick-borne encephalitis infection causes a significantly large changes in cytogenetic regimens using buccal epithelium in the elderly than in younger patients. Restoring cytogenetic norms observed in a group of young in 3 months after hospitalization, in the elderly - in 6 months. When comparing cytogenetic effects of encephalitis shows: the young patients tick-borne encephalitis level by routine cytogenetics abnormal cells was significantly higher in carriers of inactive forms of gene GSTM1 (0)/GSTT1 (0) than containing active homozygous variants of these genes. Such patterns have not been noted in a group of elderly patients.

Abstract
The numbers of participants over 75 years of age in previous studies of oral health have not been sufficient to permit a full investigation of the influence of age on the mouth. In this study a disproportionate stratified random sample of 255 independent elders was selected from a list of urban voters to provide similar numbers of men and women in three age groups. The subjects were interviewed and examined, and nearly half of them had mucosal disorders. There was a significant (P

Abstract
Laminin-5 is a glycoprotein which mediates epithelial cell adhesion to the basement membrane. This study describes the distribution and synthesis of laminin-5 in oral lichen planus, epithelial dysplasias, squamous cell carcinomas and a lymph node metastasis using immunohistochemistry and in situ hybridization. In normal oral mucosa and lichen planus, immunoreaction to the laminin-5 was seen as a thin continuous, delicate line in the basement membrane region, although slight irregularities in the thickness and intensity of the immunoreaction could be detected in some cases with lichen planus. In epithelial dysplasias, the laminin-5 staining was discontinuous and more diffuse compared to lichen planus and normal mucosa. The immunoreaction was generally extracellular, although in some cases with lichen planus and epithelial dysplasia there were a few basal epithelial cells showing cytoplasmic staining. The invasive carcinomas and the lymph node metastasis showed a striking, intense cytoplasmic, staining of the carcinoma cells along the invasive border of the neoplastic islands and in individual infiltrating carcinoma cells. Using in situ hybridization, the laminin-5 gamma 2 chain mRNA expression could not be detected in normal oral mucosa whereas, in non-dysplastic lichen planus and, more strongly, in dysplasias, there was a clear increase in the expression of laminin-5 mRNA in the basal epithelial cells. The most intensive signal was detected in the invasive front of the oral squamous cell carcinomas and the lymph node metastasis. We conclude that, in oral squamous cell carcinoma, there is altered synthesis and secretion of laminin-5 mRNA and protein. It is also evident that in dysplastic lesions of oral epithelium the synthesis and distribution of laminin-5 is abnormal.

Abstract
The object of the investigation reported in this paper was to study, from the point of view of statistical and geometric theory of pattern recognition, the DNA optical density distribution peculiarities in the interphase nuclei of buccal epithelium present in the pathology of the thyroid and mammary glands. Two new indices to characterize this distribution (ratio of modal class volumes and relief index) are proposed. It is shown that in malignant neoplasms of the thyroid and mammary glands the changes in the nuclei of buccal epithelium are characterized by an increase in the optical density of DNA over a range from 0.15 to 0.30 in conventional units of measure, as compared with its values in benign pathological processes. The sensitivity of the proposed criterion for diseases of the thyroid gland is equal to 76.2% and the specificity is equal to 85.8%. For diseases of the mammary gland (excluding IDLC) we have discovered that the sensitivity of the method is equal to 94.29% and its specificity equal to 90.91%. In diseases of the mammary gland (including IDLC) we have discovered that the sensitivity of the method is equal to 71.42% and its specificity is equal to 90.91%.

Abstract
In the buccal epithelial micronuclear test, only the higher frequency of cells with any nuclear degenerative changes is considered to be attributable to the adverse influence of environmental factors. Comprehensive examination of 223 children of 5-7 years of age, going to kindergartens and schools has indicated that the frequency of cells with nuclear chromatin condensation and incomplete nuclear lysis decreased when ambient air contamination was increased in the territories of children's establishments and when the child's throat was contaminated with Staphylococcus aureus or the pharyngeal resident microflora inhibited. Some poor conditions of the nasal and buccal mucosae were also associated with the increase or decrease of cell frequencies. It is suggested that nuclear chromatin condensation and nuclear lysis (rather than other signs of cell degeneration and death) reflect natural cell aging. A moderate toxic effect causes epitheliocytic physiological development retardation and a more intensive effect accelerates aging of cells and induces their death.

Abstract
Incidence of oral cavity squamous cell carcinomas is rising worldwide, and population characterization is important to follow for future trends. The aim of this retrospective study was to present a large cohort of primary oral cavity squamous cell carcinoma from all four health regions of Norway, with descriptive clinicopathological characteristics and five-year survival outcomes.
Patients diagnosed with primary treatment-naïve oral cavity squamous cell carcinomas at all four university hospitals in Norway between 2005-2009 were retrospectively included in this study. Clinicopathological data from the electronic health records were compared to survival data.
A total of 535 patients with primary treatment-naïve oral cavity squamous cell carcinomas were identified. The median survival follow-up time was 48 months (range 0-125 months) after treatment. The median five-year overall survival was found to be 47%. Median five-year disease-specific survival was 52%, ranging from 80% for stage I to 33% for stage IV patients. For patients given treatment with curative intent, the overall survival was found to be 56% and disease-specific survival 62%. Median age at diagnosis was 67 years (range 24-101 years), 64 years for men and 72 years for women. The male: female ratio was 1.2. No gender difference was found in neither tumor status (p = 0.180) nor node status (p = 0.266), but both factors influenced significantly on survival (p

Abstract
From a total material of 184 Swedish users of loose packed moist snuff and 68 users of portion-bag packed moist snuff, cases were selected from subgroups based on a four-point clinical grading scale. The selected material for the study comprised 70 cases (ten from each clinical grade group, no Degree 4 lesion was found among portion-bag users). Features recognized in biopsies from these cases together with findings in previous studies correlated well with the use of a four-point scale for the grading of clinical changes, especially in the context of discriminating lesions for which special efforts should be undertaken to make the patient stop or change the snuff dipping habit and for selecting patients in whom regular clinical follow-up including a biopsy should be carried out. In this article is also discussed the labeling of the clinical oral mucosal changes seen at the site where a quid of snuff is regularly placed. The conceptual use of "snuff dippers' lesions" is recommended instead of e.g. snuff-induced leukoplakia.

Abstract
In a survey of oral mucosal lesions in 20,333 individuals, 1,466 individuals with snuff dipper's lesions were found. All but seven of the snuff dippers were men, which gives a prevalence of snuff dipper's lesions of 15.9% in the male population. Four degrees (1-4) of clinical severity of lesions were allotted. There were positive correlations between the severity of the lesion and years with the habit, daily amount of snuff used, time with contact between snuff and the oral mucosa, and, to some extent, with age of the snuff dipper. There were differences between the different brands of snuff as regards the severity of the snuff dipper's lesion produced.

Abstract
BACKGROUND: Collagen XVIII is a ubiquitous basement membrane (BM) component and a precursor of endostatin. METHODS: Using immunohistochemistry and in situ hybridization, we studied the expression and localization of collagen XVIII in different stages of normal oral wound healing, epithelial dysplasia and squamous cell carcinoma (SCC). RESULTS: In mild epithelial dysplasias collagen XVIII appeared as a continuous signal in the BM, whereas in severe epithelial dysplasias and in the invasive areas of oral SCCs collagen XVIII was absent. In situ hybridization showed that collagen XVIII mRNA expression did not decrease in severe dysplasia or oral carcinoma samples when compared with the mild dysplasias. CONCLUSIONS: The results indicate that the absence of collagen XVIII protein in severe oral dysplasias is related to the processing of the protein rather than to changes in mRNA expression.

Abstract
This investigation comprises a longitudinal (2 yr) study of development in oral and general health among 100 institutionalized elderly people in Gothenburg. The aim of the study was to photographically document variations in oral health in relation to variation in the general health of these individuals during the period of the project. Changes noted from one examination to the next were limited to a judgment of an "unchanged", "deteriorated", or "improved" status. Medical analyses were based upon information collected from medical charts and the subjective impressions of the care staff, and odontological analyses were based upon photographic screening according to a set of given criteria. Results demonstrated a relation between developments in oral and general health among older people. The strongest relationships were registered between changes on the tongue and general health. The project has shown that a standardized photographic follow-up of health developments in oral tissues can be a valuable aid in cooperative efforts between medical physicians and dentists regarding health supervision of the elderly.
