Abstract

Background: Symptoms such as headache, dizziness, nausea, cough and sneeze, irritated mucous membrane, eyes, throat, nose, inflammation and itching skin are associated with one of indoor air quality diseases, called sick building syndrome. The aim of this study was to assess the prevalence of symptoms of the syndrome and some related factors in educational hospital intensive care nurses in Kerman University of medical sciences. Methods: This study was a cross-sectional study. All intensive care nurses who were willing to cooperate in the study were enrolled in the census. The standard MM040EA questionnaire associated with sick building syndrome and indoor air quality was used in this study to determine prevalence of this syndrome. Data collected from the questionnaires were analyzed using chi-square test and ANOVA. Results: Some symptoms included lack of focus (60.2%), headache and fatigue (58.3%), dry and irritated skin (57.3%) and eye irritation (48.5%) were more common than other symptoms. The syndrome did not depend on age, gender, employment and working conditions, and environmental factors. Environmental factors influence the development of the syndrome, including the noise and unpleasant smell the workplace (P<0.05). Conclusion: According to high prevalence of sick building syndrome in nurses and its relationship to environment noise and unpleasant smell work, more attention to improvement of environment conditions, such as increasing the efficiency of air conditioning and fresh air to enhance the quality of work life for nurses segments and increase the efficiency of motivation of the working environment is needed.

Abstract

Background: In continuing our work on effects of noise stress, this study aimed to determine the effect of noise stress on the anxiety and the volume of the amygdale nuclei as a key brain component plays role in the anxiety. Methods: In this experimental study, two-months old Wistar male rats were randomly divided into noise stress and control groups (n=10 in each group). Control rats were maintained under standard laboratory conditions and noise-stressed rats were exposed to 75 dB noise (1100Hz), 20 min/3 times/day for 90 days. The anxiety behaviors were assessed applying elevated plus maze and Territory discrimination test. Coronal serial sections of 25 µm thickness through rat amygdale were made. Every 2th section was selected and the volume of amygdale nuclei was determined by using Cavalieri's principle. Results: Results indicated that the noise-exposed rats had fewer entrances to open arm of elevated plus maze and spend less time in this arm. In territory discrimination test, noise stressed group had more latency to enter in unknown compartment. The volume of lateral nucleus of amygdale was significantly higher in noise stressed group compared to control animal. Conclusion: Result of this study indicated that the chronic exposure to noise induces anxiety behavior and caused increase in central nucleus of amygdale volume. In this view, our experimental research may present a useful approach in understanding some aspects of the pathophysioloy of anxiety disorders due to noise stress.

Abstract

Background: The effect of depression upon life quality, especially upon those suffering from sleep disorders, is of considerable importance, hence in this study we have undertaken the study of depression in persons suffering from sleep disorders, on the basis of polysomnography test and have dealt with some of its important factors. Methods: This study is a cross-sectional study which was conducted upon patients visiting the sleep disorder clinic of the Baharloo hospital, during the years 1388-1391. Polysomnography was conducted upon them and their sleep disorder was diagnosed on this basis, commencing the study on them. Every subject was then given a data collection sheet, and some of the sleep disorder questionnaires, and then the Beck questionnaire were filled up for them. After collection of this data for the patients and also for the control group, the data was analyzed and evaluated with the help of statistical software. Results: The mean age of the patients suffering with breathing disorder during sleep was 50.22±12.13 and significantly higher than the mean age of patients suffering from insomnia 44.20±17.76 (P=0.02). Also, no significant statistical difference was noticed in this study in the Beck questionnaire scores between the two groups diagnosed for sleeplessness and obstructive apnea during sleep (P>0.05). Conclusion: In the present study we noticed that the Beck depression score for patients suffering from sleeplessness was higher than those suffering from obstructive apnea during sleep, although this difference was not significant. This can be due to the insufficient number of sleep disturbance patients observed in this study. Hence, it is suggested that another study be conducted by taking a higher number of subjects belonging to this group.

Abstract

Introduction: Lead has been recognized as one of the most dangerous occupational exposures that have acute and chronic effects on major organs of the human body such as the effects on central and peripheral nervous system, hematopoietic, gastrointestinal, renal and cardiovascular systems. Blood lead measurement is an essential step for early detection and treatment of lead poisoning. There are different methods for blood lead level measurement. Each has advantages and disadvantages. In this paper, we compared the common methods for measuring blood lead level in terms of technique, accuracy, availability, and costs. Methods: Based on the available literature, we evaluated various methods of lead measurement and compared from different aspects. Results: Our studies have shown that “Inductively Coupled Plasma Mass Spectrometry” (ICP-MS) has the highest accuracy and the highest levels of costs among the available methods. After that, “Graphite furnace atomic absorption spectrometry” (GFAAS) method have the best accuracy and is the most common procedure that used for the blood lead measurement in laboratories. “Anodic stripping voltammetry” (ASV) is a newer method and have lower costs and ease of use, but its accuracy is at a lower level. This method can be used on site as well. Conclusion: Comparison of different methods showed that we can apply any of these methods depending on desired accuracy, costs and existing facilities for lead measurement in occupational medicine. Using of new literatures in this field could help us to better evaluation of lead poisoning.

The aim of this research was to determine the prevalence of musculoskeletal disorders in various organs of the carver, assessing the carotid posture and workstations, determine the individual and ergonomic risk factors the occurrence of musculoskeletal disorders
 Method:
The present study is done through descriptive cross-section method to assess the organic risk work-related musculoskeletal disorders that loom over 152 handloom weavers. Our data collection tools were: demographic questionnaire, job Nordic questionnaire, and body map prevalence of musculoskeletal disorders to decide the rate of symptoms. Then, we took film from handloom weavers while wearing to know the condition of their bodies. After reviewing the films, we assigned posture marks to each duty using ocra software at the end, data were analyzed and T-test using spss-20.
Result:
The result Ocra showed that the most frequent incidence of pain in different organs of the body during last year was neck and shoulder the average Ocra is 3.65.This indicate that most of the handloom weavers are at high risk and are in the red zone. According to the statistics 1.3% of these weavers are in slight risk and 32.2% are at low risk and 64.4% are at high risk. Thus, our study showed that the level of exposure to the risk in level 4 is more than the other levels. Hence, the station needs immediate correction.
The results also showed that there is a significant relationship between the risk level of Ocra and the prevalence of musculoskeletal disorders (pain, discomfort, etc., during the past 12 months) in the neck, shoulder and wrist.
Conclusion:
Based on Ocra indices results, handloom weavers are at high risk of musculoskeletal injuries that indicates the inappropriate (unsuitable) work condition and environment that should be corrected as soon as possible.
On the other hand, the Ocra method of evaluation is an appropriate tool to confirm the level of risk factors in the muscoskeletal disorders of handloom weavers.
