BACKGROUND Tannery workers are at considerable risk of developing occupational contact dermatitis. Occupational skin diseases in tannery workers in newly industrialized countries have been reported, but neither the prevalence of occupational allergic contact dermatitis nor the skin-sensitizing agents were specifically examined in those studies. OBJECTIVES To assess the prevalence of occupatio...

Laboratory testing of contact phenomena can be prohibitively expensive if the interacting bodies are geometrically complicated. This work demonstrates means to mitigate such problems by exploiting the established observation that two geometrically dissimilar contact pairs may exhibit the same contact mechanics. Specific formulas are derived that allow a complicated Hertzian contact pair to be r...

Contact lens wearers are at great risk of developing microbial keratitis because of incorrect usages and unhygienic maintenance of contact lenses. Therefore, the present study was planned to provide data that will be helpful in selecting the anti-microbial to cure microbial keratitis. One hundred bacterial isolates from conjunctiva of contact lenses wearer were isolated, identified and subjecte...

Background & Aims of the Study: Azo dyes are used in industrial processes such as textile industry to produce large quantities of colored effluents that contain organic and non-organic materials. So, effective and efficient treatment of them is important for the environmental protection. The aim of this study was to evaluate the efficiency of powder and granular pumice for the ...

A 29-year-old female, an aesthetician, developed occupational allergic contact dermatitis caused by extracts of crude drugs. The results of 48-hour closed patch testing showed positive reactions to the moisturizing cream and oil that she used in her work. This cream and oil included Scutellraria Baicalensis, mugwort (Artemisia vulgaris), and Artemisia capillaris,Gardenia. The results of patch t...

BACKGROUND Patch testing is an essential procedure in the investigation of eczema in children. OBJECTIVES To analyse the frequency of contact hypersensitivity and allergic contact dermatitis among Polish children with eczema. PATIENTS/METHODS During an allergy screening programme involving 9320 children aged 7 and 16 years, 12.6% reported symptoms of chronic/recurrent eczema. From this grou...

The motion of robots and objects in our world is often highly dependent upon contact. When contact is expected but does not occur or when contact is not expected but does occur, robot behavior diverges from plan, often disastrously. We describe an approach that uses multi-rigid body simulation with contact toward predicting likely such behavioral divergences on real robots. Our approach, and ot...

Contact tracing, coupled with molecular epidemiologic investigation, is especially useful for identifying an infection with few cases in the population, such as human immunodeficiency virus (HIV) infection in China. No such research is available on Chinese men who have sex with men (MSM). From 2008 to 2010 in Taizhou Prefecture in China, every newly diagnosed HIV-infected MSM was invited to par...

Communications to the Editor on condom usage except in case 3. Natural rubber has been well known to cause contact dermatitis. Recently other allergic reactions to rubber or latex products, such as rhinitis, asthma, and anaphylaxis, have also been described.2 Seaton and Cherrie reported a case of rubber glove asthma, and Turjanmaa et al described allergic reactions to nibber condoms. Were there...
