The implied involvement of intravascular bubbles shunted from venous to arterial circulations is inconsistent with the frequent absence of cerebral symptoms in these cases. If arterial bubbles reach the labyrinthine artery, they must also be distributing widely in the brain. This discrepancy could be explained by slower inert gas washout from the inner ear after diving and the consequent tendency for arterial bubbles entering this supersaturated territory to grow because of inward diffusion of gas. Published models for inner ear and brain inert gas kinetics were used to predict tissue gas tensions after an air dive to 4 atm absolute for 25 min. The models predict half-times for nitrogen washout of 8.8 min and 1.2 min for the inner ear and brain, respectively. The inner ear remains supersaturated with nitrogen for longer after diving than the brain, and in the simulated dive, for a period that corresponds with the latency of typical cases. It is therefore plausible that prolonged inner ear inert gas supersaturation contributes to the selective vulnerability of the inner ear to short latency decompression sickness in divers with right-to-left shunt.

Markers of tobacco smoke were measured together with other compounds typical of tobacco smoke and indoor air. The measurements were carried out at stationary sampling points in smoking and non-smoking areas of the restaurants in 2005-2006, when at least half of the service area had to be non-smoking according to the Finnish Tobacco Act. The average concentrations (geometric mean, microg/m3) of the 16 airborne contaminants measured in the smoking area were: nicotine 18.1; toluene 10.6; isoprene 10.2; m,p-xylene 5.0; limonene 4.8; benzene 3.3; furfuryl aldehyde 3.2; 1,3-butadiene 2.7; 3-ethenylpyridine (3-EP) 2.5; phenol 2.1; ethyl benzene 1.7; pyridine 1.6; o-xylene 1.5; 3-picoline 1.4; styrene 1.2; and naphthalene 0.45. A good correlation (r=0.90-0.99, p<0.001) was obtained between tobacco-specific markers (3-EP and nicotine) and 1,3-butadiene, isoprene, pyridine, furfuryl aldehyde, 3-picoline, phenol, and styrene. A poor or no correlation (r=0.19-0.60) was obtained between 3-EP or nicotine and the rest of the compounds. The average concentrations of all compounds were significantly lower in the non-smoking area than in the smoking area (p<0.05). In the non-smoking area, the average concentration of 3-EP was 0.35 microg/m3 and that of nicotine 1.6 microg/m3. In three restaurants, the area design and ventilation were effective: the average level of 3-EP in the non-smoking section was <3% from that in the smoking section. In the other restaurants, tobacco smoke was spreading more freely and the corresponding value was 14-76%. A sensitive method was applied for the measurement of airborne 1,3-butadiene. The air samples were collected into Carbopack X adsorption tubes and analysed by thermal desorption/gas chromatography/mass selective detection. The precision of the method was 4.2% (at 100 ng/sample) and the limit of quantification 0.02 microg/m3.

To address this gap, we examined the association of psychosocial characteristics (i.e., sociodemographics, risk perception, social norms, and pluralistic ignorance) with waterpipe, cigar, and cigarette smoking in college freshmen. Data are from a cross-sectional internet survey conducted during spring semester 2004 at Johns Hopkins University, N=411. Multinomial logistic regression was used to determine the association between psychosocial risk factors and waterpipe, cigar, and cigarette smoking. Results reveal that (1) psychosocial risk profiles of smokers differed by type of smoker and by type of tobacco product smoked, and (2) freshmen perceived the waterpipe as the most attractive product, out of the three products evaluated, to use among their peers. This study provides some of the first data on the association of psychosocial characteristics and various forms of tobacco smoking in young adults. This area of research is of increasing importance as a surge of waterpipe use among college students is becoming evident and interventions to reduce and prevent use are critically needed.

METHODS: In a cross-sectional telephone survey of smokers in a representative general population sample in Norway, we compared the measures. We assessed (i) internal consistency reliability with Cronbach's alpha; (ii) compared item scores; and (iii) tested the validity of the questionnaires. Test-retest reliability was assessed in a smaller convenience sample. RESULTS: Among 1265 respondents (64%), 290 (23%) were daily smokers and included in further analysis. Their mean age was 42 years [standard deviation (SD) 15] and 46% were female. They smoked on average 13 cigarettes per day (SD 6). Internal consistency reliability was 0.61 for the FTND (n = 267) and 0.81 for the CDS-12 (n = 266). Score distributions suggested a floor effect for the FTND. Test-retest reliability was 0.90 for the FTND and 0.97 for the CDS-12 (n = 31). The correlation between the scale scores and a question about the maximum willingness to pay for a cigarette after not smoking all day was 0.36 (P < 0.001) for the FTND (n = 262) and 0.45 (P < 0.001) for the CDS-12 (n = 263). There was little difference in the associations of the two scales or their abbreviated versions with external variables. CONCLUSIONS: Telephone administration was acceptable for both questionnaires, and we have established population reference values for the four scales. The questionnaires were associated with each other and showed similar properties. The findings support the construct validity of the scales.

This popularity is most noticeable among youths, and is surpassing cigarette smoking among this group in some societies. Many factors may have contributed to the recent waterpipe spread, including the introduction of sweetened/flavored waterpipe tobacco (known as Maassel), its reduced-harm perception, the thriving cafe culture, mass media and the internet. The passage of smoke through water on its way to the smoker underlies much of the common misperception that waterpipe use is less harmful than cigarettes. The health/addictive profile of waterpipe compared to cigarettes is largely unresearched and is likely to be influenced by the properties of smoke, duration and frequency of use, type of tobacco used, volume of smoke inhaled and the contribution of charcoal. However, the accumulation of evidence about the harmful and addictive potential of waterpipe use is outpacing the public health response to this health risk. A timely public health and policy action is needed in order to curb the emerging waterpipe smoking epidemic.

Overall, 374 bacterial isolates were collected from six kajmak samples of different ages produced in the households located in distinct regions of Serbia. In order to identify lactic acid bacteria present in chosen samples of kajmak, total 349 Gram-positive and catalase-negative isolates were analyzed. The recognition of isolates was performed by phenotypic characterization followed by molecular identification using (GTG)(5)-PCR and sequence analysis of 16S rRNA gene. Leuconostoc mesenteroides and Enterococcus faecium were the most frequently isolated species from kajmak samples. In contrast, leuconostocs and enterococci were found in BGMK3 and BGMK1 kajmak respectively, only after using enrichment technique for isolation suggesting they are present in low numbers in these kajmaks. Lactococcus lactis, Lactococcus raffinolactis and Lactococcus garvieae were also found in those samples but in lower proportion. Results showed that Lactobacillus plantarum, Lb. paracasei and Lb. kefiri were the most frequently isolated Lactobacillus species in analyzed kajmaks.

The aims of this study were to assess the prevalence of RLS with transcranial doppler ultrasonography in 49 divers referred for spinal cord DCS and compare it with the prevalence of RLS in 49 diving controls, and to determine a potential relation between RLS and lesion site of spinal cord. The proportion of large RLS was greater in DCS divers than in healthy control divers (odds ratio, 3.6 [95 % CI, 1.3 to 9.5]; p = 0.017). Shunting was not associated with the increased incidence of cervical spinal cord DCS (OR, 1.1 [95 % CI, 0.3 to 3.9]; p = 0.9) while a significant relationship between large RLS and spinal cord DCS with thoracolumbar involvement was demonstrated (OR, 6.9 [95 % CI, 2.3 to 20.4]; p < 0.001). From the above results, we conclude that the risk of spinal cord DCS in divers with hemodynamically relevant RLS is higher than in divers without RLS, particularly in their lower localization.

STUDY DESIGN: Cross-sectional (conducted in the course of a cohort study). SETTING: Cardiff, UK, 1989 and 2000. METHODS: Plaque was recorded, as was presence or absence of bleeding on probing and loss of attachment (LA). Information concerning tobacco smoking was obtained from questionnaire data. RESULTS: At age 19-20 years, smokers had statistically significantly (P < 0.01) higher whole mouth mean plaque scores than non-smokers. Whole mouth mean bleeding scores, however, were similar in smokers and non-smokers. The relationship of plaque to smoking was very similar at age 30-31, yet bleeding scores were approximately 25% lower in smokers than in non-smokers (P < 0.01). Whole mouth LA scores showed small, statistically non-significant differences between smokers and non-smokers. At the age of 30-31 years, gender and social class had a negligible confounding effect on oral hygiene, gingival and periodontal health in smokers and non-smokers. CONCLUSIONS: Smokers consistently demonstrated poorer oral hygiene than non-smokers. The effect of smoking in reducing gingival bleeding was already apparent at age 19-20 years despite the fact that, at this time, subjects might be assumed to have been exposed to a relatively small dose of tobacco over a short period of time. In the follow-up study conducted at the age of 30-31 years, the impact of smoking on the periodontal tissues was, as expected, more pronounced.

Bonding to cervical enamel can generate significantly lower bond strengths than bonding to other enamel areas. The effect of enamel pretreatment on bond strengths of self-etch and self-adhesive resin cements to cervical enamel remains undetermined. PURPOSE: The purpose of this study was to evaluate cervical enamel bond strengths of self-adhesive, self-etch resin cements according to acid pretreatment, using a total-etch resin cement as the control. MATERIAL AND METHODS: The proximal surfaces of 20 extracted molars were sectioned to obtain 40 enamel rectangles with an area of 8.0 x 4.0 mm. The rectangular enamel specimens were assigned to 1 of 5 enamel experimental groups: intact enamel + RelyX Unicem (UN), etched enamel + UN (UNpa), intact enamel + Multilink (ML), etched enamel + ML (MLpa), and the total-etch-based RelyX ARC (RX; control group). Standard 8.0 x 4.0 x 6.0-mm composite resin blocks (Z250) were cemented to all specimens. The bonded enamel surfaces were sectioned into sticks with a cross-section of 0.8 +/-0.2 mm(2) and tested to failure in tension mode at a crosshead speed of 1 mm/min. The data were submitted to 1-way analysis of variance (ANOVA), followed by Tukey's HSD post hoc test (alpha=.05). Additionally, the enamel etching pattern was investigated for all experimental groups using field-emission electron microscopy. RESULTS: Statistical analysis showed significant differences among different resin cements (P RX (19.40 (9.47)). Acid etching of enamel before application of self-etch resin cement did not improve the mean bond strengths (SD) for self-etch resin cement [ML (5.38 (5.97)); MLpa (5.23 (1.1))]. Self-adhesive and self-etch resin cements yielded the lowest significant mean bond strengths (SD) when applied on intact enamel: UN (13.03 (2.82)) > ML (5.38 (5.97)). Scanning electron microscopy showed a consistent etching pattern for phosphoric acid-etched specimens. Self-etch and self-adhesive resin cements applied directly to intact enamel showed inconsistent areas of etching. CONCLUSIONS: Etching cervical enamel surfaces resulted in significantly higher bond strengths for self-adhesive resin cement. For self-etch resin cement, etching did not improve bond strength.
