The prevalence of respiratory and other health problems in a cohort of highway toll booth workers was surveyed by mailed questionnaire. In a low proportion of respondents (43.2%), a high prevalence of central nervous system complaints (headaches, irritability, or anxiety, and unusual tiredness), mucous membrane irritation (eye irritation, nasal congestion, and dry throat), and musculoskeletal problems (joint and back pains) was found. We believe these symptoms are reflective of the acute irritant and central nervous system effects of exposure to motor vehicle exhaust. The musculoskeletal complaints are likely the result of bending, reaching, and leaning out of the toll booth. The need for in-depth evaluation of the ventilation systems and the ergonomic and job stressors of work at toll booths is suggested by these results.

Self-administered questionnaires were used to find out the prevalence among employees working in the three local authority premises in a Health District of self-reported illness which could be associated with sick building syndrome. Eye symptoms were found to be more common among employees working in a typing centre using VDUs. The symptoms tiredness, lethargy and influenza-like ('flu-like) illness, including aches in the limbs, were reported in significantly higher numbers by employees working in areas where there was evidence of increased pressure of work and worries over job losses. Dry throat and blocked or stuffy nose were symptoms reported in significantly higher proportions by employees working in certain buildings, where anecdotal evidence suggested that there could be problems with temperature regulation. This study also confirmed findings by other studies that for some symptoms women complain in significantly higher numbers than men. It was concluded that the type of work people do, in addition to the type of building they work in, play an important role in self-reported illnesses. Causation of sick building syndrome is complex and probably of multifactorial origin.

Some vocal disorders in teachers are associated with occupational factors, but there are few studies that analyze the influence of vocal habits, fluid intake, mastication, and sleep on these disorders. The objective was to analyze the occurrence of vocal fatigue, hoarseness, and dry throat in elementary and high school teachers and their association with vocal habits, fluid intake, mastication, and sleep. A sample of 422 elementary and secondary school teachers was studied using a specific questionnaire. The multiple regression analysis showed that hoarseness was associated with absence of water intake (odds ratio (OR)=1.7; P=0.047), yelling/speaking loudly (OR=1.6; P=0.058), jaw-opening limitations (OR=3.8; P=0.003), average of 6 hours of sleep/night (OR=1.7; P=0.039), and waking-up feeling replenished (OR=2.0; P=0.020). The presence of vocal fatigue was significantly associated with yelling/speaking loudly (OR=2.2; P=0.013), speaking excessively (OR=2.4; P=0.023), difficulty to open the mouth to masticate (OR=6.6; P=0.003), less than 6 hours of sleep (OR=4.0; P=0.008), and waking-up feeling replenished (sometimes OR=2.8; P=0.003; or never OR=3.3; P=0.002). The presence of dry throat was associated with being a former smoker (OR=3.3; P=0.011) and having jaw-opening limitations (OR=3.9; P=0.021). In recent years, speech and hearing interventions with teachers have focused on health-care promotion actions and prevention of vocal disorders, prioritizing issues related with hydration and healthy vocal use habits. However, the findings in the present study show the need to further focus on lifestyle habits related to sleep and eating habits.

Waste treatment processes produce odours and biological emissions to the environment, but their health effects are controversial. The aim of our study was to assess odour-associated self-reported physical symptoms among residents living near waste treatment centres. The study was conducted in the surroundings of five large-scale Finnish waste treatment centres with composting plants. In 2006, 1142 randomly selected residents living within 1.5, 3.0 and 5.0 km of these centres were interviewed by telephone. A questionnaire with 102 items asked about respondent's personal characteristics, odour exposure and symptoms during the preceding 12 months. Physical symptoms were analysed by distance to the waste treatment centre and by the respondent's perception and annoyance of waste treatment odour. The residents who were classified as "annoyed of the odour" reported following physical symptoms more than the others did: unusual shortness of breath (OR 1.5, 95% CI 1.0-2.2), eye irritation (1.5, 1.1-2.1), hoarseness/dry throat (1.5, 1.1-2.0), toothache (1.4, 1.0-2.1), unusual tiredness (1.5, 1.1-2.0), fever/shivering (1.7, 1.1-2.5), joint pain (1.5, 1.1-2.1) and muscular pain (1.5, 1.1-2.0). Moreover, the ORs for almost all other physical symptoms were elevated among the annoyed respondents. Reported odour annoyance near the waste treatment centres showed an association with many physical symptoms among residents living in the neighbouring areas.

This study investigated whether sick building syndrome (SBS) complaints among office workers were associated with the indoor air quality. With informed consent, 417 employees in 87 office rooms of eight high-rise buildings completed a self-reported questionnaire for symptoms experienced at work during the past month. Carbon dioxide (CO2), temperature, humidity and total volatile organic compounds (TVOCs) in each office were simultaneously measured for eight office hours using portable monitors. Time-averaged workday difference between the indoor and the outdoor CO2 concentrations (dCO2) was calculated as a surrogate measure of ventilation efficiency for each office unit. The prevalence rates of SBS were 22.5% for eye syndrome, 15.3% for upper respiratory and 25.4% for non-specific syndromes. Tiredness (20.9%), difficulty in concentrating (14.6%), eye dryness (18.7%) were also common complaints. The generalized estimating equations multivariate logistic regression analyses showed that adjusted odds ratios (aORs) and 95% confidence interval (CI) per 100 ppm increase in dCO2 were significantly associated with dry throat (1.10, 95% CI=(1.00-1.22)), tiredness (1.16, 95% CI=(1.04-1.29)) and dizziness (1.22, 95% CI=(1.08-1.37)). The ORs for per 100 ppb increases in TVOCs were also associated with upper respiratory symptoms (1.06, 95% CI=(1.04-1.07)), dry throat (1.06, 95% CI=(1.03-1.09)) and irritability (1.02, 95% CI=(1.01-1.04)). In conclusion, the association between some SBS symptoms and the exposure to CO2 and total VOCs are moderate but may be independently significant.

Glehnia littoralis Fr. Schmidt ex Miq, the sole species in the genus Glehnia (Apiaceae), has long been used in traditional Chinese medicine to treat fatigue, weakness, stomach-yin deficiency, lung heat, cough, dry throat, and thirst. Recently, G. littoralis has also been incorporated into a wide range of Chinese vegetarian cuisines. Based on the comprehensive information, advances in botany, known uses, phytochemistry, pharmacology, and toxicity of G. littoralis, we aim to highlight research gaps and challenges in studying G. littoralis as well as to explore its potential use in plant biotechnology. This may provide more efficient therapeutic agents and health products from G. littoralis. A literature search of SciFinder, ScienceDirect, Scopus, TPL, Google Scholar, Baidu Scholar, and Web of Science, books, PhD and MSc dissertations, and peer-reviewed papers on G. littoralis research was conducted and comprehensively analyzed. We confirmed that the ethnomedical uses of G. littoralis have been recorded in China, Japan, and Korea for thousands of years. A phytochemical investigation revealed that the primary active compounds were phenylpropanoids, coumarins, lignanoids, and flavonoids, organic acids and derivatives, terpenoids, polyacetylenes, steroids, nitrogen compounds, and others. Our analysis also confirmed that the extracts of G. littoralis possess immunoregulatory, antitumor, anti-inflammatory, hepatoprotective, antioxidant, neuroprotective, antibacterial, antifungal, and analgesic properties. Although further studies are required, there is strong evidence of the antitumor and immunoregulatory potential of G. littoralis. Also, more studies are needed to elucidate the mechanisms of action of its active compounds (e.g., falcarinol and panaxydiol) before any clinical studies can be carried out.
