  • General Statistical Measures Of Occupational Injury And Illness

    In this section we provide a brief overview of the extent of occupational illness and injury. Much of our focus is on the United States, where conditions and production processes are comparable to those in developed industrialized nations worldwide. Both the nature of work, the distribution of jobs in various workplaces, the extent of exposure,…

  • Oral Cancer Awareness By The General Public And Health Professionals

    Many studies have reported variable, and frequently suboptimal, levels of knowledge of oral cancer, risk factors, and diagnosis among both the public and health-care professionals. Although it is among the ten most common cancers worldwide, OSCC is rarely mentioned in the popular press, and public awareness is dismal (Canto et al., 1998). Significant numbers of…

  • Potentially Malignant (Precancerous) Clinical Lesions

    Some potentially malignant (precancerous) clinical lesions that can progress to OSCC include especially: Erythroplasia (erythroplakia): The most likely lesion to progress to severe dysplasia or carcinoma. Erythroplastic lesions are velvety red plaques, which in at least 85% of cases show frank malignancy or severe dysplasia. Carcinomas are seen 17 times more frequently in erythroplakia than…

  • Environmental Contamination And Human Exposure

    PCBs entered the air, water, and soil during the manufacture and use in a variety of applications. PCB wastes are placed in landfills. PCBs also entered the environment from accidental spills and leaks during the transport of PCB-containing materials. Once in the environment, PCBs do not readily break down and therefore remain there for a…

  • Classes Of Organohalogens And Background Information

    Chlorinated hydrocarbons were synthesized as early as 1830. Polychlorinated biphenyls (PCBs) were first synthesized in the early 1880s by Schmidt and Schultz (1881) and their commercial production began in 1929. Commercial PCB formulations were sold under a variety of trade names; for example, in the United States and Great Britain Aroclor was the most common…

  • Organohalogen Pollutants and Human Health Research Paper

    What Are Organohalogens? It is axiomatic that human activities change the quality of the environment on a global scale, which can adversely affect life on earth. A prototypical example of such environmental damage and harmful biological effects is that caused by persistent human-made chemicals, particularly organohalogen compounds. Organohalogens are organic compounds that contain chlorine, bromine,…

  • Neuropathology And Neurochemistry

    The pathological hallmark of PD was considered to consist of intracellular eosinophilic inclusions called Lewy bodies. These occur inside neurons in the substantia nigra, presumably in dopamine (DA)-containing cells. Lewy bodies probably accumulate in neurons undergoing degeneration. The number of DA neurons in the substantia nigra progressively diminishes in PD. It is important to note…

  • A Public Health Response Informed By Human Rights Principles

    As the UNAIDS Director Dr. Piot points out, the exceptional nature of AIDS requires an exceptional response and that includes responding to the rights of infants, children, and adolescents. Unfortunately, there is a lack of public discourse on how this pandemic has negatively affected the lives of millions of children. The United Nations Convention on…

  • The Global HIV/AIDS Pandemic And Orphaned And Vulnerable Children

    Patterns of illness, human rights abuses, and orphanhood that characterize the global HIV/AIDS pandemic are not forged by chance. Rather, poverty and economic inequities, the absence of educational opportunities, exploitative child labor, and pervasive violations of women’s and children’s rights produce the patterns of human suffering that are the subject of this research paper. A…

  • Potential Human Health Effects Of Air Pollution-Related Climate Change

    The global nature of air pollution dispersion raises the issue of the potential impacts on global climate change of human emissions of carbon dioxide (CO2) and other greenhouse gases such as methane (CH3). These gases are natural constituents of the atmosphere, and they are necessary for the maintenance of the Earth’s climate in that they…
