Abstract
This study was conducted to investigate the prevalence of pulmonary problems, among a group of 1600 selected textile mill workers in the Yazd province. A standard questionnaire on respiratory symptoms was administered and forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were determined for each worker. The results obtained were as follow: Obstructive ventilatory defect 15 cases (0.9 percent), restrictive ventilatory defect 16 cases (1 percent), combined obstructive and restrictive ventilatory defect (Mix) 53 cases (3.3 percent) and normal 1516 cases (94.8 percent).

Abstract
Background: Mechanical low back pain (L.B.P) is most common in middle-aged people especially in developing countries and the symptom compromises routine life activities of the patients. Disk herniation is the most frequent cause of LBP. The less costly way for diagnosing the cause of LBP is performing a careful physical examinations. This study aimed to evaluate the sensitivity and specificity of clinical diagnosis of the cause of Discal Sciatic Neuralgia at Construction Labors in comparison to MRI as the gold standard.
Methods: In a descriptive- analytic study 60 middle-aged professional construction workers were evaluated. Their age range was 25-45 years old and all of them had the complaint of mechanical LBP. Medical history was taken and all cases under went a cautious physical examination. The presence of disk herniation between L4-L5 orL5-S1 was recorded according to clinical signs and symptoms. Lumbosacral MRI was performed for all cases and the results were compared to clinical data.
Results: The clinical diagnosis of presence and severity of pathology was confirmed by MRI in all stages of discopathy in L5-S1 and L4-L5 vertebrae (sensitivity= 100%).
Conclusion: This study showed that careful physical examinations will be sufficient for the sciatic neuralgia diagnosis and even the staging of disk herniation can be performed clinically. Requesting MRI as an expensive procedure is not recommended for diagnosis of Discal sciatic neuralgia because of feasibility of the cost effective way of precise physical examination.

Abstract
Background: Health care workers (HCWs) are at substantial risk of acquiring bloodborne pathogen infections through contact with blood and other potentially infectious materials. The main objectives of this study were to determine the epidemiological characteristics of occupational exposure to blood/body fluids, related risk factors of such exposure, and hepatitis B vaccination status among HCWs.
Methods: This cross-sectional study was conducted from December 2004 to June 2005 at three university hospitals in Tehran, Iran. Using a structured interview, we questioned HCWs who had the potential for high-risk exposure during the year preceding the study.
Results: With a total number of 467 exposures (52.9%) and an annual rate of 0.5 exposures per HCW, 391 (43%) of the 900 HCWs had at least one occupational exposure to blood and other infected fluids during the previous year. The highest rate of occupational exposure was found among nurses (26%) and the housekeeping staff (20%). These exposures most commonly occurred in the medical and emergency wards (23% and 21%, respectively). The rate of exposure in HCWs with less than five years of experience was 54%. Percutaneous injury was reported in 280 participants (59%). The history of hepatitis B vaccination was positive in 85.93% of the exposed HCWs. Sixty-one percent had used gloves at the time of exposure. Hand washing was reported in 91.4% and consultation with an infectious disease specialist in 29.4%. There were 72 exposures to HIV, HBV and HCV exposure to HBV was the most common. In 237 of the enrolled cases, the source was unknown. Job type, years of experience and hospital ward were the risk factors for exposure.
Conclusion: Education, protective barriers and vaccination are important in the prevention of viral transmission among HCWs.

Abstract
Background: Dermal- respiratory reactions to latex glove is a common problem and
sometimes life threatening. Among health care workers, dental working personnel have
extensive use of latex gloves. A few numbers of researches have been done in Iran about
prevalence of these reactions but there is no comprehensive study for dental workers. The
purpose of this study was to evaluate reactions to latex gloves amongst dental workers in
military dental health centers.
Methods: In this cross-sectional descriptive survey, dental workers with a minimum of
three months length of employment and most often use of latex gloves were asked to fill
standard questionnaire (derived from South Carolina Medical University) regarding latex
related clinical manifestation and personal medical history and predisposing factors Data
analysis was done by χ2 and Student's t test.
Results: In our study 330 personnel were assessed. The mean age and length of
employment was 31.6 and 8 years respectively. The most occupation was dentistry. A
total of 232 subjects (70.3%) reported latex gloves-allergic symptoms. 72 (21.8%) of
persons have history of atopy and food allergy was seen in 114 (34.5%). 63 (19.1%) of
subjects reported history of hand dermatitis. All of these predisposing factors had
positive regression with dermal and respiratory reactions.
Conclusion: In this survey the prevalence of allergic reactions was higher than similar
studies which may be due to type of gloves, lack of preemployment assessments and
other factors. Use of diagnostic methods such as serologic measures, SPT and pulmonary
function testing (such as spirogram) could be considered as tools for confirmatory and
differential diagnosis and important complementary for these studies. Because of
relationship between allergic reactions to latex gloves and some medical histories, it
seems to be necessary for preemployment evaluation and periodic health surveillance of
dental workers.

Abstract
Background: Healthy vision of workers is one of the important elements in carpet weaving
industry which has essential role in improving of the job quality and efficiency. Visual acuity
is the primary outcome measure in most studies involving eye diseases. Ihe aim of this study
was determination of visual acuity and its effective factors in women carpet weaver in fordu
rural area of Qom has been investigated.
Methods: In a cross-sectional (descriptive-analytical) study visual acuity of 177 women
carpet weaver has been determined. Job hours per day, job history, age, literacy, trauma
history, diabetes history, family history of eye diseases, eye diseases history and family size
of subjects were determined .
Results: The results of study indicated that the right eyes visual acuity of 72.4 % of women
were desirable (0 – 0.8) and 27.6 % were undesirable (0.9-1.2). These results for the left eyes
were 69.5 % and 30.5 % respectively. In addition, the result showed that with increasing the
job hours and history and age, percent of women with undesirable both eyes visual acuity
were increased. With higher literacy levels, percent of women with undesirable both eyes
visual acuity decreased. In subjects with truma history, the undesirable visual acuity was
higher. In this study the relation between visual acuity and job history, age, literacy, truma
history and eye diseases history were statistically significant (in all cases P<0.05).
Conclusions: High percentage of women carpet weaver were in undesirable visual acuity
and in this study the relation between visual acuity and job history, age, literacy, trauma
history and eye diseases history were statistically significant (in all cases P<0.05).

Abstract
Background: In the last decade, the use of microwave ovens throughout the world, including Iran, has increased significantly. Therefore, it is important to understand the knowledge, attitude, and behavior of microwave oven use among employees of the Eastern Health Center to promote safe and responsible practices in the workplace. Assessing their familiarity and attitudes with microwave ovens, this study aims to identify potential areas for improvement and training. This, in turn, can create a safer and more efficient work environment for all involved.
|
Methods: In this cross-sectional study in 2022, the study population was all employees working in the health center and comprehensive health service centers affiliated with the East of Shahid Beheshti University of Medical Sciences, numbering 162 people. The research tool was a questionnaire adapted from Nadiri's thesis (2015). After collecting the questionnaires, the data was obtained by SPSS 26 software and were analyzed using Pearson's correlation coefficient, multiple regression, independent t-test, and one-way ANOVA.
Results: Although the attitude (36.35±3.579) and the behavior (61.16±6.402) towards using microwave ovens are favorable, there is still room for improvement of knowledge and awareness. Knowledge has a positive and significant effect on behavior (P=0.002, B=0.245) and attitude (P=0.001, B=0.263), which shows that improving knowledge about the safe and responsible use of microwave devices can lead to behavior. and a more favorable attitude among employees. In addition, the attitude has a strong positive and significant effect on behavior (P=0.001, B=0.417), and promoting a positive attitude toward using microwave devices can also lead to more favorable behavior. However, the relatively weak effect of awareness on attitude indicates that other factors may also play a role in determining the attitude toward using microwave devices.
Conclusion: These findings highlight the importance of educational and awareness campaigns to promote the safe and responsible use of microwave devices among healthcare workers.
