Abstract
Two micro-extraction methods, air-agitated liquid-liquid microextraction (AALLME) and dispersive liquid-liquid microextraction (DLLME), have been compared with each other by applying them for the analysis of five triazole pesticides (penconazole, hexaconazole, diniconazole, tebuconazole and triticonazole) in aqueous samples by gas chromatography with flame ionization detection (GC-FID). In the AALLME method, which excludes any disperser solvent, much less volume of organic solvent is used. In order to form fine and dispersed organic droplets in the aqueous phase, the mixture of aqueous sample solution and extraction solvent is repeatedly aspirated and dispensed with a syringe. In the DLLME method, an appropriate mixture of extraction solvent and disperser solvent is rapidly injected by a syringe into the aqueous sample. Effect of the pertinent experimental factors on DLLME (i.e. identity and volume of the extraction and disperser solvents and ionic strength) and on AALLME (identity and volume of the extraction solvent, number of agitations, and ionic strength) were investigated. Under optimal conditions, limits of detection for the five target pesticides obtained by AALLME-GC-FID and DLLME-GC-FID ranged from 0.20 to 1.1ngmL(-1) and 1.9 to 5.9ngmL(-1), respectively. The relative standard deviations (RSDs, n=5) were in the range of 1-4% and 3-5% with the enrichment factors of 449-504 and 79-143 for AALLME-GC-FID and DLLME-GC-FID, respectively. Both of the compared methods are simple, fast, efficient, inexpensive and can be applied to the analysis of the five pesticides in different aqueous samples in which penconazole and hexaconazole were found. For spiked samples, the recoveries were in the ranges of 92-105%, and 92-104% for AALLME and DLLME, respectively.

Abstract
BACKGROUND: Populations at risk for esophageal adenocarcinoma remain poorly defined. Laryngeal symptoms can be secondary to laryngopharyngeal reflux (LPR) and can occur without associated gastroesophageal reflux symptoms such as heartburn and regurgitation. GOAL: We sought to determine the prevalence of Barrett esophagus (BE) in otolaryngology patients with laryngeal symptoms+/-typical gastroesophageal reflux disease (GERD) symptoms. STUDY: We performed a cross-sectional study of otolaryngology clinic patients who reported laryngeal symptoms. Symptoms, medications, and exposure histories were obtained. Unsedated transnasal endoscopy was performed. Suspected BE was biopsied and confirmed histologically. Risk factors and prevalence of BE were assessed. RESULTS: Two hundred ninety-five patients were enrolled [73% male, median age 60 y (interquartile range 51 to 68 y)]. The overall prevalence of BE was 11.8% (n=33). Antisecretory medication use was present in 56% (n=156) of patients at enrollment. Compared with patients without BE, patients with BE were more likely to be male (P=0.01) and to report occupational lung injury (P=0.001). Duration, but not severity of laryngeal symptoms, significantly increased the odds of BE (odds ratio, 5.64; 95% confidence interval, 1.28-24.83; for a duration of symptoms >5 y). Of patients with BE, 58% (n=19) had coexisting LPR and GERD symptoms and 30% (n=10) had only LPR symptoms. Presence and size of hiatal hernia and length of columnar-lined esophagus were significant risk factors for BE. CONCLUSIONS: Long-standing laryngeal symptoms are associated with the presence of BE in otolaryngology patients. Patients with chronic laryngeal symptoms and no identifiable ear, nose, or throat etiology for those symptoms may benefit from endoscopic screening regardless of whether typical GERD symptoms are present.

Abstract
OBJECTIVES: The aim of the study was to assess data for the oral health behaviour and oral health of dental assistants (DAs) and patients (PTs) who regularly received preventive dental care. METHODS: One-hundred DAs (38.8 years) and 100 PTs (44 years) participated in the study conducted in the Unstrut-Hainich region of Thuringia, Germany. A questionnaire established oral hygiene and smoking habits. The dental examination included the caries index DMF-T, evaluation of the periodontal situation (PSI) as well as gingival inflammation [papilla bleeding index (PBI)]. RESULTS: Seventy-seven DAs and 46 PTs used dental floss regularly. Twenty-four DAs and 27 PTs were smokers. The mean DMF-T of DAs was 12.5, which was significantly lower than the DMF-T of PTs (17.0) (P

Abstract
OBJECTIVES: To assess work-related exposure to tobacco smoke in Finnish restaurants, a series of nationwide questionnaire surveys were conducted among restaurant workers and the levels of indoor air nicotine concentrations were measured in restaurants. The survey aimed to evaluate the impact of the smoke-free legislation in general and in particular after the total smoking ban launched in 2007. MATERIALS AND METHODS: In 2003-2010, four national questionnaire surveys were conducted among restaurant workers and the concentration of nicotine in indoor air was measured in different types of restaurants, bars and nightclubs. RESULTS: Between 2003 and 2010, the proportion of restaurant workers reporting occupational exposure to tobacco smoke dropped from 59% to 11%. Among pub workers, the decrease was from 97% to 18% and in workers of dining restaurants from 49% to 10%, respectively. The median concentration of nicotine in indoor air of all restaurants decreased from 11.7 mug/m(3) to 0.1 mug/m(3). The most significant decrease was detected in pubs where the decrease was from 16.1 mug/m(3) to 0.1 mug/m(3). Among all restaurant workers, in 2003-2010 the prevalence of daily smokers was reduced from 39% to 31% in men and from 35% to 25% in women. CONCLUSION: Total prohibition of smoking but not partial restriction in restaurants was effective in reducing work-related exposure to tobacco smoke. Strict tobacco legislation may partly be associated with the significant decrease of daily smoking prevalence among restaurant workers.

Abstract
BACKGROUND: In the 20th century, 100 million people across the globe lost their lives due to consumption of tobacco. Every year 15,000 deaths in Nepal are attributable to tobacco smoking and using other products of tobacco. This study aimed to establish the proportion and the social determinants of tobacco use among Nepalese men based on the Nepal Demographic and Health Survey (NDHS), 2011. METHODS: This study used the NDHS 2011 data. The prevalence of cigarette smoking, other forms of tobacco 16 smoking and use of tobacco in any form is reported as a percentage (%). The significance of association of the statistically significant variables established using Chi-square test was further tested by using multiple logistic regression. RESULTS: Of the 4121 participants, the prevalence of consuming any form of tobacco was 51.9% [95% confidence interval (CI) (49.6%- 54.3%)]; chewing/sniffing tobacco was 34.8% (95% CI: 32.4%- 37.3%) and tobacco smoking was 33.6% (95% CI 31.3%-36.0%).Men with no education [Odds Ratio (OR) 3.477; 95% CI (2.380-5.080)], from an older age group (36-49) [OR 2.399; 95% CI (1.858-3.096)] who were from a manual occupation [OR 1.538; 95% CI (1.188-1.985)], who were married[OR 1.938; 95% CI ( 1.552-2.420)], and who were from the Terai region [OR 1.351; 95% CI (1.083-1.684)] were more likely to consume tobacco. Men who watched television at least once a week [OR 0.642; 95% CI (0.504-0.819)] were less likely to consume tobacco. CONCLUSIONS: The current study showed that over half of Nepalese men consume tobacco. There is an urgent need to fully implement Nepal's Tobacco Control and Regulation Act which will ban smoking in public places; enforced plain packaging and display of health warnings over 75% of the packaging, and has banned selling of tobacco products to those under 18 years of age. There is a need to increase the social unacceptability of tobacco in Nepal by raising awareness through different electronic and cultural media. Anti-tobacco campaigns should focus on those who are less educated, have manual occupations, are in poorer economic groups, and are from the Terai region of Nepal.

Abstract
The asymmetric unit of the title compound, 2C15H16N6O3.C3H7NO.H2O, contains two independent ethyl 6-methyl-2-oxo-4-[4-(1H-tetra-zol-5-yl)phen-yl]-1,2,3,4-tetra-hydro-pyrim-id-ine- 5-carboxyl-ate mol-ecules, in which the dihedral angles between the tetra-zole and benzene rings are 20.54 (12) and 12.13 (12) degrees . An intra-molecular C-Hcdots, three dots, centeredO hydrogen bond occurs in each mol-ecule. In the crystal, N-Hcdots, three dots, centeredO, N-Hcdots, three dots, centeredN, O-Hcdots, three dots, centeredO and O-Hcdots, three dots, centeredN hydrogen bonds, as well as weak C-Hcdots, three dots, centeredO and C-Hcdots, three dots, centeredN hydrogen bonds, link the mol-ecules into a three-dimensional supra-molecular architecture. pi-pi stacking is also observed between parallel tetra-zole rings of adjacent mol-ecules, the centroid-centroid distance being 3.482 (6) A.

Abstract
Neuroendocrine tumors (NET) are a diverse group of tumors that derive from epithelial cells with neuroendocrine differentiation. Gastroenteropancreatic NETs are a subset of NET that arise from the gastrointestinal tract. The natural history and prognosis varies widely between different gastroenteropancreatic NETs, highlighting the importance of identifying accurate prognostic and predictive biomarkers. At the 2013 ASCO Gastrointestinal Cancers Symposium, De Braud et al. (Abstract #186) and Bellister et al. (Abstract #163) present data on two new possible biomarkers.

Abstract
In Taiwanese alternative medicine Lu-doh-huang (also called Pracparatum mungo), mung beans are mixed with various herbal medicines and undergo a 4-stage process of anaerobic fermentation. Here we used high-throughput sequencing of the 16S rRNA gene to profile the bacterial community structure of Lu-doh-huang samples. Pyrosequencing of samples obtained at 7 points during fermentation revealed 9 phyla, 264 genera, and 586 species of bacteria. While mung beans were inside bamboo sections (stages 1 and 2 of the fermentation process), family Lactobacillaceae and genus Lactobacillus emerged in highest abundance; Lactobacillus plantarum was broadly distributed among these samples. During stage 3, the bacterial distribution shifted to family Porphyromonadaceae, and Butyricimonas virosa became the predominant microbial component. Thereafter, bacterial counts decreased dramatically, and organisms were too few to be detected during stage 4. In addition, the microbial compositions of the liquids used for soaking bamboo sections were dramatically different: Exiguobacterium mexicanum predominated in the fermented soybean solution whereas B. virosa was predominant in running spring water. Furthermore, our results from pyrosequencing paralleled those we obtained by using the traditional culture method, which targets lactic acid bacteria. In conclusion, the microbial communities during Lu-doh-huang fermentation were markedly diverse, and pyrosequencing revealed a complete picture of the microbial consortium.

Abstract
BACKGROUND: Smoking from a water pipe has become increasingly popular, but this is not as innocent as it seems. CASE DESCRIPTION: Three women presented to the emergency department after having smoked from a water pipe. The first patient had experienced a syncopal episode and still had symptoms of dizziness and a headache afterwards. The second patient only had a headache and the third had no symptoms. The physical examinations and standard vital sign measurements of all three patients were normal. Analyses of the arterial blood gases, however, showed carbon monoxide (CO) poisoning: the patients had HbCO concentrations of 22, 19.5 and 5.7%, respectively. We administered high concentrations of oxygen to each, but the first 2 patients continued to experience symptoms for several weeks. The CO poisoning was probably caused by the incomplete combustion of the charcoal in the water pipe which resulted in CO being released. CONCLUSION: The regular or even one-time use of a water pipe containing tobacco or an aromatised substance can cause CO poisoning. Patients can continue to experience symptoms for weeks after an episode of acute CO poisoning.

Abstract
The adverse effects of smoking have fostered a natural market for smoking cessation and smoking reduction products. Smokers attempting to quit or reduce consumption have tried everything: "low" or "light" cigarettes; nicotine-infused chewing gum, lozenges, and lollipops; dermal patches; and even hypnosis. The latest craze in the quest to find a safer source of nicotine is the electronic cigarette. Electronic cigarettes (e-cigarettes) have swept the market, reaching a rapidly expanding international consumer base. Boasting nicotine delivery and the tactile feel of a traditional cigarette without the dozens of other chemical constituents that contribute to carcinogenicity, e-cigarettes are often portrayed as less risky, as a smoking reduction or even a complete smoking cessation product, and perhaps most troubling for its appeal to youth, as a flavorful, trendy, and convenient accessory. The sensationalism associated with e-cigarettes has spurred outcry from health and medical professional groups, as well as the Food and Drug Administration (FDA), because of the unknown effects on public health. Inhabiting a realm of products deemed "tobacco products" under recent 2009 legislation, e-cigarettes pose new challenges to FDA regulation because of their novel method of nicotine delivery, various mechanical and electrical parts, and nearly nonexistent safety data. Consumer use, marketing and promotional claims, and technological characteristics of e-cigarettes have also raised decades old questions of when the FDA can assert authority over products as drugs or medical devices. Recent case law restricting FDA enforcement efforts against e-cigarettes further confounds the distinction among drugs and medical devices, emerging e-cigarette products, and traditional tobacco products such as cigarettes, cigars, and smokeless tobacco. This Article investigates the e-cigarette phenomenon in the wake of the recently enacted Family Smoking Prevention and Tobacco Control Act of 2009 (TCA). It examines the tumultuous history of attempts at tobacco regulation by reflecting on the history of Congressional activity to regulate tobacco sales and promotion. Furthermore, this Article suggests a feasible approach to strengthening regulation of e-cigarettes under the existing statutory framework. This approach includes increased scrutiny of manufacturer and distributor claims that trigger drug and medical device provisions, utilization of new tobacco product and modified risk tobacco product provisions, and promulgation of new FDA regulations and guidance specifically directed at e-cigarettes.
