Municipal sewage treatment plant workers are potentially exposed to a multitude of industrial chemicals and pathogenic microorganisms. A questionnaire survey of working habits, lifestyle and symptoms of illness was conducted among 189 municipal sewage treatment plant workers processing between three and ten million gallons of wastewater daily in 16 plants in New York State between March and July of 1984. Water treatment plant workers in the same cities comprised the comparison group. Sewage workers reported a significantly higher frequency of headache, dizziness, sore throat, skin irritation and diarrhea within the month immediately preceding receipt of the questionnaire, after controlling for various possible confounders. Eye and skin irritation were significantly associated with exposure to mutagens. The health significance of these findings and possible sources of error in assessing risk are discussed.

In this questionnaire study, the authors compared the prevalence of certain symptoms and signs associated with Sick Building Syndrome and perceptions relative to environmental discomfort of employees in a central-air-conditioned dropping center and in natural-ventilation commercial shops located on the streets of Niteroi, Rio de Janeiro, Brazil. There was a statistically significant higher prevalence of symptoms (e.g., water and itching of eyes, sore throat, nose irritation, difficulty breathing, skin irritation, sneezing) that were characteristic of Sick Building Syndrome in the air-conditioned building than in the naturally ventilated stores. The results indicated that there exists a continuing need for further research in Brazilian work environments.

Formaldehyde (FA) is an occupational and general indoor hazard often affecting the respiratory airways. One of the main causes of multiple chemical sensitivity is gaseous FA, and it has become an important social problem in developed countries. FA concentrations in anatomy dissection classrooms are thought to be higher than under usual circumstances. The number of students developing physical symptoms during the anatomy dissection course in our university has been increasing over recent years. We planned to clarify the causes of such symptoms. Ninety-five medical students were interviewed using a questionnaire about allergic histories, physical symptoms developed during the anatomy dissection course, and symptoms related to chemical sensitivity up to three months after the course had finished. We measured total IgE, specific IgE to FA and specific IgE to house dust mites. Eighty-three percent of students had experienced symptoms, such as burning eyes, nasal discharge, sore throat, general fatigue or skin irritation during the course. Fifty percent of students had a past history of atopic disease. Fifty-eight percent of students tested positive to specific IgE to house dust mites; however, only one student, who did not complain of any symptoms during the course, tested positive to FA-IgE. Students with atopic factors (present histories of atopic diseases and higher total IgE) and/or chemical sensitivity demonstrated worse physical symptoms during the anatomy dissection course than students without such histories. In conclusion, it is suggested that gaseous FA exposure may exacerbate basic allergic symptoms, and moreover that people with chemical sensitivity demonstrated worse symptoms following gaseous FA exposure. Nevertheless, in our study we find no relationship between FA-IgE and the physical symptoms of gaseous FA exposure during or following an anatomy dissection course.

Flurbiprofen, a potent nonsteroidal anti-inflammatory drug, is widely used for relief of pain in patients suffering from rheumatic diseases, migraine, sore throat and primary dysmenorrheal. However, this drug has many gastrointestinal side effects produced by its oral administration, such as gastric bleeding and peptic ulcer. These effects were responsible for non-compliance among patients, which ultimately results in treatment failure. The physicochemical properties of flurbiprofen, make it a suitable candidate for transdermal drug delivery, which can overcome the drawbacks of oral administration. In this sense, microemulsions have been proved to increase the cutaneous absorption of lipophilic drugs when compared to conventional drug delivery systems. The purpose of this study was to formulate and characterize gel based microemulsions, for topical delivery of flurbiprofen. Different gel bases, containing microemulsion and hydro-alcoholic solution of flurbiprofen, were developed and compared. In vitro study showed that gels containing microemulsion had a higher permeation rate than those containing hydro-alcoholic solutions. Additionally, formulation of Carbopol-I (microemulsion) showed higher percent of inhibition of inflammation than others bases. Further, skin irritation study demonstrated that Carbopol-I was none irritating. Flurbiprofen microemulsion incorporated on Carbopol-I showed physicochemical, in vitro and in vivo characteristics suitable for the development of alternative transdermal delivery formulation.
