In West Bengal, India, although more than 6 million people are exposed to arsenic through drinking water, only 15-20% showed arsenic-induced skin lesions, including premalignant hyperkeratosis. This indicates toward some factors that confer susceptibility to arsenic-induced carcinogenicity. In this work, we wanted to explore whether differences in DNA(More)
Cytogenetic biomarkers are essential for assessing environmental exposure that can predict adverse human health effects such as cellular damage. Chromosomal aberrations are the most important cytogenetic end-points successfully used for the cancer risk assessment of populations occupationally or environmentally exposed to different toxic chemicals.

This is a retrospective study of 348 patients with burn injuries admitted to a peripheral industrial hospital over a period of 10 years. The patients were from all walks of life. The study compared the incidence of burns occurring in various industries and those in other situations, assessed the morbidity and mortality profile of burn injuries treated in a(More)
Owing to the established roles of human macrophages in immune defense, we investigated the effect of chronic arsenic exposure upon these major hematopoietic cells in 70 arsenic-exposed individuals with skin lesions and 64 unexposed individuals. Human monocyte-derived macrophages were prepared from peripheral blood mononuclear cells, by culture of the(More)
BACKGROUND Allergic contact dermatitis is one of the important occupational hazards in construction workers and it often leads to poor quality of life of the workers with substantial financial loss. However, this is often a neglected entity. There are no past studies on the construction workers in Indian subcontinent. OBJECTIVE This pilot study has been(More)
BACKGROUND Individual variability in arsenic metabolism may underlie individual susceptibility toward arsenic-induced skin lesions and skin cancer. Metabolism of arsenic proceeds through sequential reduction and oxidative methylation being mediated by the following genes: purine nucleoside phosphorylase (PNP), arsenic (+3) methyltransferase (As3MT),(More)

Hand, foot, and mouth disease (HFMD), first reported in New Zealand in 1957 is caused by Coxsackievirus A16 (CVA16) and human enterovirus 71 (HEV71) and occasionally by Coxsackievirus A4-A7, A9, A10, B1-B3, and B5. This is characterized by erythematous papulo vesicular eruptions over hand, feet, perioral area, knees, buttocks and also intraorally mostly in(More)
Arsenic (As) induces pre-malignant and malignant dermatological lesions, non-dermatological health effects and cancers in humans. Senescence involves telomere length changes and acquisition of senescence-associated secretory phenotype (SASP), which promotes carcinogenesis. Though in vitro studies have shown that As induces senescence, population based(More)
BACKGROUND Arsenic is a natural drinking water contaminant affecting 26 million people in West Bengal, India. Chronic arsenic exposure causes cancer, cardiovascular disease, liver disease, neuropathies and ocular diseases. The aims of the present study were to assess bioindicators of hepatocellular injury as indicated by the levels of liver enzymes, to(More)
