“…[5,7] e mean interval between the occupational exposure to cement and the onset of the dermatitis noted by us (11.1 years), was comparable to the finding of Iraji et al (10-15 years). [8] History of atopy noted in 44% of our patients was consistent with the frequency of atopy noted in a previous study (37.5%). [7] e commonly affected sites and the morphology of the lesions noted by us were comparable to the previous studies.…”

Objectives: The objective of the study was to identify the allergens showing positive patch test reaction (using Indian standard battery of allergens) in cement workers with clinically diagnosed allergic contact dermatitis (CD) to cement attending a tertiary referral center. Materials and Methods: We included cement workers with clinically diagnosed allergic CD to cement who attended the dermatology outpatient clinic of our tertiary referral center from January 2013 to December 2013. We did patch testing in all the cases ( after subsidence of active dermatitis) with Indian standard battery of patch test allergens and documented the allergens that showed a positive reaction. Results: Forty-seven (94%) of the 50 study participants showed a positive reaction to one or more of the allergens. The most common allergen that showed a positive reaction was potassium dichromate (43/50, 86%). Twenty-five patients (50%) showed positive reactions to more than 1 allergen. Four patients (8%) showed positive reactions only to allergens that were not seen in cement. Limitations: Small sample size and lack of information on clinical response of dermatitis to avoidance of identified allergen were the major limitations. Conclusion: Twenty-five (50%) patients showing positive reactions to more than 1 allergen tested and 4 (8%) showing positive patch test reaction to none of the allergens in cement (but to other allergens) highlight the role of patch testing in identifying the probable allergens in patients with clinically diagnosed allergic CD to cement.

“…Generally, production workers, the engineers, maintenance and quarry workers had similar health profiles compared to other categories of workers. The prevalence of dermatitis and eczema related to cement dust among these workers is already documented among cement workers elsewhere [27][28][29]. Similarly, respiratory diseases are reported commonly by workers that had frequent and continuous exposure to dust [16,30,31] including cement.…”

The concentrations of pollutants associated with cement production and the effects on ambient air and community health were assessed in this study. Suspended particulates were monitored using a Negretti 1000 TM air sampler. Additionally, an Ogawa TM sampler was employed to assess levels of selected gaseous pollutants at selected sites. To collect data on health status, a questionnaire survey was used for selected neighbouring communities and clinic records for industry workers. The data were analysed with the aid of percentage, variation test, correlation and regression statistics. Mean concentrations of particulate matter of 10 μ (74-338 μg/m 3 ) and 2.5 μ (28-116 μg/m 3 ) were significantly higher than permissible limits (50 μg/m 3 and 10 μg/m 3 ) within and around the production plant. At all sites, levels of sulphur dioxide (0.1-12 ppb), nitrogen dioxide (0.1-13 ppb) and carbon monoxide (0.1-1.7 ppm) were below the allowable limits for human exposure. Analysis of variance showed significant spatial variations (p < 0.01) in the concentrations of the monitored pollutants; higher concentrations were monitored at sites in proximity to factory location. The health profile of the factory workers and some residents of neighbouring communities showed high levels of respiratory and skin infections. Enforcement of law with regard to compliance on emissions and creation of a buffer zone around the cement factory would safeguard the environment and human health.

“…In addition, 100% of cement workers had contact dermatitis after 10 or less years of work. 17 Moreover, a review article in 2015 reported that statistically significant positive association between tobacco smoking and hand eczema prevalence rate was found in 20 articles. The association was stronger for studies in occupational settings than for population-based studies.…”

OBjeCTiveS: First, this research was instituted to identify common allergens, and second, to test the association between IL16 gene promoter polymorphism rs4778889 T/C and allergic contact dermatitis (ACD). MeThODS:A case control study was conducted in dermatology outpatients' clinic. Study subjects received interview-based semi-structured questionnaire, complete skin examination, IL16 gene promoter was investigated by PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis, and IQ Ultra™ patch test units (Chemotechnique Diagnostics AB, Sweden) with 10 substances were used. ReSulTS:Most of the prevalent cases had positive patch test (93.3%). The most common clinical presentation of ACD in our patients was itching (96.7%), followed by dryness (86.75%), erythema (76.7%), and fissuring (76.7%). There was higher CC gene distribution among cases, but there was no statistically significant difference. IL16 gene distribution was nearly similar among different clinical presentations. Formaldehyde showed statistically significant higher frequency for CC. The most common allergen found was mercury chloride (76.6%), followed by potassium dichromate (26.6%) and cobalt chloride (20%). COnCluSiOnS:The current study found prominent metal sensitization (mercury chloride) over the previously known potassium dichromate. There was no statistically significant IL16 gene distribution among cases compared with control. However, C allele was more frequently encountered in cases. Further studies are required to test the association with IL16 genotype and ACD and highlight the new trends in metal sensitization among cement-exposed workers.This study included 2 groups:Cases: A convenience sample of 30 construction workers suffering from ACD mainly attributed to cement exposure;Control: A sample of 90 age-and sex-matched healthy subjects (from service workers and laboratory workers in Mansoura Faculty of Medicine who have never been exposed to cement and did not have history of any type of allergy).
