A total of 42 subjects with history of hubble-bubble smoking were recruited for this study. A corresponding group with a history of cigarette smoking and controls were matched. All subjects underwent laryngeal video-endostroboscopic evaluation and acoustic analysis. In the hubble-bubble smoking group, 61.9% were males. The average age was 30.02 +/- 9.48 years and the average number of years of smoking was 8.09 +/- 6.45 years. Three subjects had dysphonia at the time of examination. The incidence of benign lesions of the vocal folds in the hubble-bubble group was 21.5%, with edema being the most common at 16.7% followed by cyst at 4.8%. The incidence of laryngeal findings was significantly higher in the hubble-bubble group compared to controls. In the cigarette-smoking group, the most common finding was vocal fold cyst in 14.8% followed by polyps in 7.4%, and edema, sulcus vocalis and granuloma. These findings were not significantly different from the hubble-bubble group except for the thick mucus, which was significantly higher in the latter. There were no significant changes in any of the acoustic parameters between hubble-bubble smokers and controls except for the VTI and MPT, which were significantly lower in the hubble-bubble group. In comparison with the cigarette-smoking group, hubble-bubble smokers had significantly higher Fundamental frequency and habitual pitch (p value 0.042 and 0.008, respectively). The laryngeal findings in hubble-bubble smokers are comparable to cigarette smokers. These laryngeal findings are not translated acoustically, as all the acoustic parameters are within normal range compared to controls.

STUDY DESIGN: Prospective study. MATERIAL: Eighteen non-dysphonic subjects (seven men and 11 women) with a history of hubble-bubble smoking and no history of cigarette smoking underwent acoustic analysis and laryngeal video-stroboscopic examination before and 30 minutes after hubble-bubble smoking. RESULTS: On laryngeal video-stroboscopy, none of the subjects had vocal fold erythema either before or after smoking. Five patients had mild vocal fold oedema both before and after smoking. After smoking, there was a slight increase in the number of subjects with thick mucus between the vocal folds (six, vs four before smoking) and with vocal fold vessel dilation (two, vs one before smoking). Acoustic analysis indicated a drop in habitual pitch, fundamental frequency and voice turbulence index after smoking, and an increase in noise-to-harmonics ratio. CONCLUSION: Even 30 minutes of hubble-bubble smoking can cause a drop in vocal pitch and an increase in laryngeal secretions and vocal fold vasodilation.

Tobacco may be combusted (e.g., cigarettes, bidis, kreteks); heated (e.g., waterpipes, hookah, nargile); or taken orally or nasally (e.g., snuff, betel quid, chewing tobacco). The predominant forms vary among cultures, but the use of cigarettes has grown most dramatically in the past century. While smoking rates among women are comparable to those among men in Europe and North America, in other regions the rate is ten or more times higher among men; this gender gap is closing among young people. Per capita tobacco use in the USA doubled in the first half of the twentieth century, and has since declined to less than the 1900 levels. While cigarettes were only 2% of tobacco consumed in the USA in 1900 (half was chewing tobacco) 50 years later they were over 80%. A similar increase in tobacco consumption, and a shift to cigarettes, has been occurring globally, with a concomitant increase in tobacco-related death and disease that is not expected to peak for another two decades.

The aim of this study was to assess the effect of nargile smoking on intra-cytoplasmic sperm injection (ICSI) outcome. STUDY DESIGN: A prospective analysis of the outcomes of 297 women who underwent ICSI treatment at the ART Unit at the American University of Beirut Medical Center between January 1, and December 31, 2006 was done. The patients were divided into 3 groups based on their smoking status: cigarette smokers (n=42), nargile smokers (n=51) and non-smokers (n=204). RESULTS: The mean age of nargile smokers was significantly lower than the other groups; however, the 3 groups were similar with respect to the cause of infertility, total dose of follicular stimulating hormone (FSH), number of oocytes and embryos obtained, and number and quality of embryos transferred. There was no significant difference in the clinical pregnancy rate between nargile smokers and non-smokers (51.0% vs 43.6%). However, cigarette smokers had a significantly lower clinical pregnancy rate compared to non-smokers (23.8% vs 43.6%, p=0.0238). On multiple logistic regression analysis, factors that decreased the clinical pregnancy rates were cigarette smoking and maternal age. CONCLUSION: Although this study did not find a deleterious effect of nargile smoking on ICSI outcome, the results need to be confirmed in prospective studies that would include larger number of women with more objective measures of nargile smoke exposure.

AIM: The purpose of this study was to examine the prevalence of cigarette and water pipe tobacco use among pupils aged 13-17 years in the urban area of Sousse, Tunisia and to identify the factors which predict current cigarette and/or waterpipe smoking in this population. METHODS: Across-sectional study was carried out on a representative sample of schoolchildren aged between 13 and 17 years in colleges and public secondary schools of the urban area of Sousse. We used a pre tested and self administered questionnaire to measure tobacco consumption. The significance level for all analyses was p<0.05. Statistical analysis was conducted with SPSS 10.0 software. RESULTS: Participants were 1569 youth. Fifty two percent of them were male. The mean age of the sample was 15+/-1.5 years. Total cigarette smoking percentage for ever and current use were 33.1% and 7.6% respectively. Total water pipe smoking percentage for ever and current use were 19.3% and 5.2% respectively. Overall, the total percentages of cigarette and water pipe smoking (ever and current) were higher for male and aged pupils. Multivariate regression analyses showed that the two types of tobacco use were related. CONCLUSION: Despite the growing adoption of water-pipe smoking, there remains limited research in this area. Increased surveillance and additional research are necessary to address this growing threat to public health.

Alcohol Pub Date Free Form / Volume 35 Issue 3 Start Page 265 Other Pages 275 Notes Place of Publication ISSN/ISBN 0741-8329 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Marijuana is the most commonly used illegal drug in the United States and is considered by young adults to be the illicit drug with the least risk. On the other hand, marijuana smoke contains several of the same carcinogens and co-carcinogens as the tar from tobacco, raising concerns that smoking of marijuana may be a risk factor for tobacco-related cancers. We reviewed two cohort studies and 14 case-control studies with assessment of the association of marijuana use and cancer risk. In the cohort studies, increased risks of lung or colorectal cancer due to marijuana smoking were not observed, but increased risks of prostate and cervical cancers among non-tobacco smokers, as well as adult-onset glioma among tobacco and non-tobacco smokers, were observed. The 14 case-control studies included four studies on head and neck cancers, two studies on lung cancer, two studies on non-Hodgkin's lymphoma, one study on anal cancer, one study on penile cancer, and four studies on childhood cancers with assessment of parental exposures. Zhang and colleagues reported that marijuana use may increase risk of head and neck cancers in a hospital-based case-control study in the United States, with dose-response relations for both frequency and duration of use. However, Rosenblatt and co-workers reported no association between oral cancer and marijuana use in a population-based case-control study. An eightfold increase in risk among marijuana users was observed in a lung cancer study in Tunisia. However, there was no assessment of the dose response, and marijuana may have been mixed with tobacco. Parental marijuana use during gestation was associated with increased risks of childhood leukemia, astrocytoma, and rhabdomyosarcoma, but dose-response relations were not assessed. In summary, sufficient studies are not available to adequately evaluate marijuana impact on cancer risk. Several limitations of previous studies include possible underreporting where marijuana use is illegal, small sample sizes, and too few heavy marijuana users in the study sample. Recommendations for future studies are to (1) focus on tobacco-related cancer sites; (2) obtain detailed marijuana exposure assessment, including frequency, duration, and amount of personal use as well as mode of use (smoked in a cigarette, pipe, or bong; taken orally); (3) adjust for tobacco smoking and conduct analyses on nonusers of tobacco; and (4) conduct larger studies, meta-analyses, or pooled analyses to maximize statistical precision and investigate sources of differences in results. Despite the challenges, elucidation of the association between marijuana use and cancer risk is important in weighing the benefits and risks of medical marijuana use and to clarify the impact of marijuana use on public health.

Pub Date Free Form / Volume 24 Issue 7 Start Page 721 Other Pages 728 Notes Place of Publication ISSN/ISBN 0829-318X Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Volatile organic compound (VOC) emissions from Sitka spruce (Picea sitchensis Bong.) growing in a range of controlled light and temperature regimes were monitored online with a proton transfer reaction-mass spectrometer (PTR-MS) operating at a temporal resolution of âˆ¼1 min. Isoprene emissions accounted for an average of more than 70% of measured VOCs and up to 3.5% of assimilated carbon. Emission rates (E) for isoprene correlated closely with photosynthetic photon flux (PPF) and temperature, showing saturation at a PPF of between 300 and 400 Î¼mol m-2 s-1 and a maximum between 35 and 38Â°C. Under standard conditions of 30Â°C and 1000 Î¼mol m -2 s-1 PPF, the mean isoprene E was 13 Î¼g g dm-1 h-1, considerably higher than previously observed in this species. Mean E for acetaldehyde, methanol and monoterpenes at 30Â°C were 0.37, 0.78 and 2.97 Î¼g gdm-1 h -1, respectively. In response to a sudden light to dark transition, isoprene E decreased exponentially by > 98% over about 3 h; however, during the first 7 min, this otherwise steady decay was temporarily but immediately depressed to âˆ¼40% of the pre-darkness rate, before rallying during the following 7 min to rejoin the general downward trajectory of the exponential decay. The sudden sharp fall in isoprene E was mirrored by a burst in acetaldehyde E. The acetaldehyde E maximum coincided with the isoprene E minimum (7 min post-illumination), and ceased when isoprene emissions resumed their exponential decay. The causes of, and linkages between, these phenomena were investigated.

Advances in methodology include the use of nested dose-response models for the parameters of the two-stage clonal expansion model, calculation of attributable risks for all exposure combinations, use of both a fixed lag and a gamma distribution to represent the time between generation of the first malignant cell and death from lung cancer, and scaling of biological parameters allowed by parameter identifiability. The cohort consists of 12,011 males working for the Yunnan Tin Corporation, with complete exposure records, who were initially surveyed in 1976 and followed through 1988. Tobacco and arsenic dominate the attributable risk for lung cancer. Of 842 lung cancer deaths, 21.4% are attributable to tobacco alone, 19.7% to a combination of tobacco and arsenic, 15.8% to arsenic alone, 11% to a combination of arsenic and radon, 9.2% to a combination of tobacco and radon, 8.7% to combination of arsenic, tobacco and radon, 5.5% to radon alone, and 8.7% to background. The models indicate that arsenic, radon and tobacco increase cell division, death and malignant conversion of initiated cells, but with significant differences in net cell proliferation rates in response to the different exposures. Smoking a bamboo water pipe or a Chinese long-stem pipe appears to confer less risk than cigarette use, given equivalent tobacco consumption. Â© 2001 by Radiation Research Society.

The usual mechanisms that produce pneumomediastinum include severe acute asthma, toxic-induced bronchial hyperreactivity, and barotrauma caused by Valsalva's maneuver (expiration through resistance). We report a case in which barotrauma resulted from repeated deep inspiration through a device with airflow resistance equivalent to MÃ¼ller's maneuver. Inspiration occurred through a homemade apparatus resembling a narrow outlet bong with 2 piled compartments. Pneumomediastinum combined with subcutaneous emphysema and pneumorachis occurred, without identified pneumothorax. There were no neurologic complications. Because of the absence of bronchospasm, expiration either through the apparatus or actively against a closed glottis, or apnea, this phenomenon is likely a result of repeated MÃ¼ller's maneuvers. Successive inhalation through resistance could have resulted in extreme negative intrathoracic pressure, which would have caused a transmural pressure gradient inducing barotrauma and release of extrarespiratory air. High-concentration oxygen therapy to achieve nitrogen washout was used.
