DOI:10.4103/0019-5278.93199  PMID:22412287
Background: Silicosis is an ancient occupational illness reported in silica mill workers, agate stone workers, slate pen workers and mining industry. However its association in flour mill workers has not been established. Aims: To study the incidence of silicosis and respiratory morbidity in flour mill workers. Settings and Design: A prospective study of 56 flour mill workers working with open silica grinding stones was undertaken. Materials and Methods: 56 flour mill workers who volunteered following information regarding the study purpose were recruited from the community. Detailed clinical and occupational history, lung functions, chest x-ray, and high resolution computed tomography (HRCT) were done. Diagnosis was made on the basis of radiological findings. Statistical Analysis: Data analysis was done with the help of the statistical package for social sciences software. The Chi-square test was used for determining the relationship between qualitative data and descriptive statistics was used where required. Results: 93% had respiratory symptoms that included cough (66.1%), dyspnea (75%), chest pain (17.1%), and rhinorrhea (46.4%). Radiological abnormalities were noted in chest X-ray (60.7%) and HRCT (81.48%). A significant correlation was seen between duration of exposure and HRCT abnormalities. Lung functions revealed obstruction in 28.5% subjects, restriction in 19%, mixed ventilatory defects in 21.4%, while 18.9% had a reduced diffusion capacity. Conclusion: Incidence of silicosis in our study on flour mill workers working with silica containing grinding stones was 30.4%. They had high respiratory morbidity (93%) cough and dyspnea being predominant symptoms. Duration of exposure correlates with radiological findings and increased incidence of silicosis.

September-December 2011, 15(3):133-136
DOI:10.4103/0019-5278.93204  PMID:22412292
Background : Hydrogen cyanide is the chemical responsible for tissue hypoxia. Chronic exposure to HCN may cause neurological, respiratory, cardiovascular and thyroid defects. Onset of symptoms depends on dose and duration of exposure. Large scale of Cassava processing could be disastrous due to discharge of hydrocyanic acid into the air. Cassava processing is the major industrial work in and around Salem. Hence the present study is taken to assess the effects of HCN exposure in Cassava workers. Materials and Methods: Thirty-nine workers from a Cassava processing unit at Salem and age-matched controls of the same economic status were taken up for this study. Clinical history was obtained with a questionnaire and their Blood sugar, lipid profile, serum total protein, urea, creatinine, AST, ALT and T 3 , T 4 , TSH were estimated using a fasting blood sample and AIP was calculated. Statistical analysis was done by student t test. Results: Our study reveals a significant increase in triglyceride in Cassava workers when compared to the control. Atherogenic index of plasma (AIP) is statistically highly significant. A significant decrease was seen in T 4. Conclusion: An increase in TGL and AIP shows a higher degree of cardiovascular risk. A decrease in T4 suggests an insufficient iodine uptake by thyroid gland. Hence a periodic medical evaluation should be done on such workers for their safety and to prevent the health hazard.

Vijay Deshpande
September-December 2011, 15(3):97-99
DOI:10.4103/0019-5278.93197  PMID:22412285
From times immemorial disasters in some form or the other have been regularly visiting humankind and humans have been trying to manage these upheavals. Noah's arch is the first such endeavor. The United Nations declared 1990-1999 as International Decade for Disaster Reduction. The Indian Government passed the Disaster Management Act 2005. As a consequence of the Act, the National Disaster Management Authority was setup. All states were given the guide lines for disaster risk reduction. The objective of this article is to get a clearer picture of what various states, educational authorities and international bodies have done and what Symbiosis International University (SIU) has done so far. Inputs from various States of the Indian Union and neighboring countries were studied. The moot question that figured all the time was "Is there a conscious effort to include Disaster Management in the curricula of various courses at the college and university level" and what are the achievements. It was seen that the Central Board for Secondary Education with support from the Ministry of Home Affairs, Ministry of Human Resource Development and United Nations Development Project have incorporated DM, as part of its frontline curriculum. Most of the Universities in the disaster prone states have enunciated policies for including DM in the curriculum, but palpable results are still awaited. In the SIU, DM has been incorporated in the curriculum and is mandatory for all undergraduate and postgraduate courses.

Sumit Prakash, Purushottam Khapre, Subrata K Laha, Nishant Saran
September-December 2011, 15(3):113-119
DOI:10.4103/0019-5278.93201  PMID:22412289
Introduction: Increasing demands, exacting management, poor ergonomics, and intense competition within and without are likely to contribute to stress among the railway engine pilots. This excess of stress and its consequences cost very high to both the organization and the consumers. Aims and Objectives: This study aims to identify the particular stressors affecting the railway engine pilots and their level of occupational stress in order to improve the safety, efficiency, and overall productivity of the railways and to propose the remedies. Materials and Methods: A cross-sectional study conducted at Central Hospital, SECR, Bilaspur, from 20/09/10 to 20/11/10, involving a study sample of 100 healthy Loco Pilots and 100 controls with similar safety category meeting the set inclusion and exclusion criteria, subjected to cross-sectional interviews and questionnaires. Results: Job stress correlated significantly with fatigue (P<0.001), ergonomics of work place (P<0.05) (particularly the postural discomfort and cab space), management pressure (P<0.01), high job demand (P<0.001), low control and low support at work (P<0.01), biological functions (P<0.05), and absenteeism (P<0.001). Top ten stressors have been identified and postural discomfort tops the list. The study also identifies minimal efforts from administration to reduce stress of its employees. Conclusion: The high demand, low control, and low support at the work with difficult work environment and inadequate recreation at the place of intermediary rest corroborates with development of stress affecting the normal biological functions leading to either avoidance of duty or making the railway engine pilots susceptible to fatigue and drowsiness, neglect, injuries, and accidents.

Rajib Biswas, Amalendu Samanta, Prasenjit Saha
September-December 2011, 15(3):120-126
DOI:10.4103/0019-5278.93202  PMID:22412290
Context: In India, a wide variety of occupations are performed in adverse indoor working environment. Work physiological studies in these jobs are scanty as compared to investigations done on more arduous outdoor occupations. Aims and Objectives: Physiological strain of workers engaged in sweet making activities was assessed in terms of cardiac strain indices in relation to heat stress. Setting and Design: 33 full-time workers from eastern India were compared for cardiac strain profile obtained during summer and winter during their regular work shift. A comparison was also done in between younger (n=12) and older (n=16) subjects. Materials and Methods : Working heart rate (WHR) was recorded continuously during work. The pulse deceleration index (PDI) was obtained from recovery heart rate (RHR). Net cardiac cost (NCC) and relative cardiac cost (RCC) were the main indices used to evaluate physical strain. Thermal stress assessed from wet bulb globe temperature (WBGT). Statistical Analysis: Students' t-test and Wilcoxon signed rank paired tests were used for comparing physiological responses. Values were considered significant when P < 0.05. Results: Work load was significantly higher in summer for all workers. RCC of younger workers in winter and summer ranged between 18% and 26%. This was significantly lower as compared to the RCC of older workers which was 27% in winter and 30% in summer. The physiological workload appeared to be moderate in nature. The WBGT index was above the recommended range in summer for both the groups. Older workers showed a no recovery pattern in terms of recovery pulse that indicated toward a cumulative stress which may be attributed to a combined effect of heat and work in summer and extra amount of work performed in winter season. Conclusion: The physical workload is aggravated with various ergonomic stressors present in the work place. An ergonomic intervention has been indicated as further scope of this study.

Working condition: A key factor in increasing occupational hazard among bidi rollers: A population health research with respect to DNA damage
Poonam Shukla, Asha Khanna, Salil K Jain
September-December 2011, 15(3):139-141
DOI:10.4103/0019-5278.93206  PMID:22412294
The present investigation was undertaken to study the role of working conditions in occupational hazards among bidi rollers occupationally exposed to tobacco dust with reference to DNA damage in peripheral blood lymphocytes. Initially, biomonitoring was conducted by estimating urinary thioether to detect the extent of xenobiotic exposure, and genotoxicity was evaluated by assessing DNA damage and micronucleus frequency in buccal epithelial cells in female bidi rollers occupationally exposed to bidi tobacco dust. Student's t-test was used to test the significance between the means. Results showed a significant increase in urinary thioether level in during-shift urine samples as compared to pre-shift samples, which indicated exposure of bidi rollers to xenobiotic compounds. A significant increase in DNA damage was observed in the rollers working in confined environment as compared to those who worked in open and mixed kind of working conditions. Keeping in view the adverse effects of tobacco inhalation on the genotoxic effects in bidi rollers as an occupational hazard and in order to minimize the hazardous effects, it is recommended that masks should be worn by the bidi rollers during work to minimize inhalation of tobacco dust. Gloves should be worn particularly if there are bruises etc. in the palm. To minimize the absorption through eyes, covered glasses should be worn. The entire process of bidi rolling may be done preferably under well ventilated conditions. Due care to be taken to sit in the direction facing the direction of wind to avoid inhalation of blown away tobacco dust.

Oxidative stress effects of thinner inhalation
Minerva Martínez-Alfaro, Yolanda Alcaraz-Contreras, Alfonso Cárabez-Trejo, Guillermo E Leo-Amador
September-December 2011, 15(3):87-92
DOI:10.4103/0019-5278.93195  PMID:22412283
Thinners are chemical mixtures used as industrial solvents. Humans can come into contact with thinner by occupational exposure or by intentional inhalation abuse. Thinner sniffing causes damage to the brain, kidney, liver, lung, and reproductive system. We discuss some proposed mechanism by which thinner induces damage. Recently, the induction of oxidative stress has been suggested as a possible mechanism of damage. This paper reviews the current evidence for oxidative stress effects induced by thinner inhalation. Early ideas about the effects of thinner on lipids are discussed in one section. We discuss several studies that have shown the oxidative effects of thinner inhalation on: lipid peroxidation, levels of antioxidant enzymes, glutathione depletion, and oxidation of proteins and DNA. We have also included studies about oxidative stress effects induced by toluene, the principal component (60-70%) of thinner. Finally, work describing the effects of oxidative stress induced by thinner inhalation on different organs is discussed.
