The Significance of a Cooperative Medical System for Treating Decompression Illness on the Izu Peninsula in Japan.

INTRODUCTION: In 2011, our hospital on the Izu peninsula began to hold meetings to discuss how to manage patients with decompression illness (DCI) to establish a cooperative medical system. We retrospectively investigated the influence of these meetings and the changes subsequently effected. METHODS: A medical chart review was retrospectively performed to investigate all cases between January 2005 and December 2017 in which the transport of patients with DCI via a physician-staffed helicopter emergency medical service (HEMS) was attempted. The patients were divided into 2 groups: the preprogram group and the postprogram group. RESULTS: There were 63 patients in the preprogram group and 65 in the postprogram group. There were no cases in which a patient's symptoms deteriorated during transportation by the HEMS. The frequency of dispatch to the scene for direct evacuation in the postprogram group (86%) was greater than that in the preprogram group (74%), but the difference was not statistically significant (P=0.09). In the postprogram group, the duration of activities at the scene or the first aid hospital was significantly shorter in comparison to the preprogram group (P=0.01). CONCLUSIONS: This retrospective study revealed simultaneity between the introduction of the yearly meetings and a reduced duration of the HEMS staff's activity at either the scene or the first aid hospital.

The World Federation of Neurology and the challenges in Environment Neurology.

Since its establishment the World Federation of Neurology (WFN) has manifested a keen interest in the environment and its relation to neurological diseases. Thus, in 2007 the WFN renamed the "Neurotoxicological Research Group" to "Environmental Neurology Research Group". In this short article, we review some recent events which illustrate the WFN involvement in Environmental Neurology as well its concerns about global health matters involving environmental issues.

[Exposome: from an intuition to a mandatory research field in occupational and enviromental medicine.] / Esposoma: da intuizione a linea di ricerca obbligata nelle Scienze Mediche Occupazionali e Ambientali.

OBJECTIVES: As Genomics aims at the collective characterization and quantification of genes, exposomics refers to the totality of lifetime environmental exposures, consisting in a novel approach to studying the role of the environment in human disease. The aim is to assess all human environmental and occupational exposures in order to better understand their contribution to human diseases. The "omics" revolution infact mostly regards the underlying method: scientific knowledge is expected to come from the analysis of increasingly extensive databases. METHODS: The primary focus is on air pollution and water contaminants, but all the determinants of human exposure are conceptually part of the idea of exposome, including physical and psychological factors. Using 'omic' techniques the collected exposure data can be linked to biochemical and molecular changes in our body. RESULTS: Since the first formulation of the idea itself of Exposome many efforts have been made to translate the concept into research, in particular two important studies have been started in Europe. CONCLUSIONS: We herein suggest that Occupational Medicine could be a precious contributor to the growth of exposure science also in its omic side thanks to the methods and to the knowledges part of our background.

Search and rescue response to a large-scale rockfall disaster.

OBJECTIVE: To describe the prehospital management and safety of search and rescue (SAR) teams involved in a large-scale rockfall disaster and monitor the acute and chronic health effects on personnel with severe dolomitic dust exposure. METHODS: SAR personnel underwent on-site medical screening and lung function testing 3 months and 3 years after the event. RESULTS: The emergency dispatch center was responsible for central coordination of resources. One hundred fifty SAR members from multidisciplinary air- and ground-based teams as well as geotechnical experts were dispatched to a provisionary operation center. Acute exposure to dolomite dust with detectable silicon and magnesium concentrations was not associated with (sub)acute or chronic sequelae or a clinically significant impairment in lung function in exposed personnel. CONCLUSIONS: The risk for personnel involved in mountain SAR operations is rarely reported and not easily investigated or quantified. This case exemplifies the importance of a multiskilled team and additional considerations for prehospital management during natural hazard events. Safety plans should include compulsory protective measures and medical monitoring of personnel.

United States Army Research Institute of Environmental Medicine: Warfighter research focusing on the past 25 years.

The United States Army Research Institute of Environmental Medicine (USARIEM) celebrated its 50th anniversary on July 1, 2011. This article reviews its history, evolution, and transition of its research programs as well as its scientific and military accomplishments, emphasizing the past 25 yr. During the 1990s, USARIEM published a series of pocket guides providing guidance for sustaining Warfighter health and performance in Southwest Asia, Somalia, the former Republic of Yugoslavia, Rwanda, and Haiti. Issues identified during Operation Desert Storm elicited research that improved nutritional guidelines for protracted desert operations; safer use of nuclear, chemical, and biological protective clothing; equipment, development, and fielding of efficient microclimate cooling systems; and effective evaluation of pharmaceuticals to protect soldiers from chemical and biological threats. During the first decade of the 21st century, USARIEM and the Department of the Army published official medical/performance doctrines for operations in the heat and cold and at high altitude. The current Global War on Terrorism focused research to improve doctrines for hot, cold, and high-altitude operations, reduce musculoskeletal training injuries, provide improved field nutrition, more efficient planning for operational water requirements, and improve both military clothing and materiel. This article also describes the critically important interactions and communications between USARIEM and deployed units and the benefits to Warfighters from this association. This report presents USARIEM's unique and world-class facilities, organizational changes, scientific and support personnel, and major research accomplishments, including the publication of 2,200 scientific papers over the past 25 yr.

The CDC fourth national report on human exposure to environmental chemicals: what it tells us about our toxic burden and how it assist environmental medicine physicians.

The Centers for Disease Control (CDC) conducts ongoing assessments of the levels of environmental chemicals in the U.S. population. This ongoing study utilizes lab samples from the individuals who are part of the National Health and Nutrition Examination Survey (NHANES). The NHANES samples from the years 1999-2000, 2001-2002, and 2003-2004 (each representing about 2,400 individuals) were used for the CDC's national reports. In the CDC Fourth National Report on Human Exposure to Environmental Chemicals ("the fourth report") complete data from the above sample years were included. Each year additional chemicals are measured; the fourth report contains information on 75 previously untested compounds, for a total of 212 compounds measured. In the fourth report, blood and urinary levels of eight different forms of arsenic are reported. The fourth report, for the first time, also includes levels of solvents (30 different compounds) and provides adult rather than juvenile values for mercury. In the majority of individuals tested, acrylamides, cotinine, trihalomethanes, bisphenol A, phthalates, chlorinated pesticides, triclosan, organophosphate pesticides, pyrethroids, heavy metals, aromatic hydrocarbons, polybrominated diphenyl ethers, benzophenone from sunblock, perfluorocarbons from non-stick coatings, and a host of polychlorinated biphenyls and solvents were found. This review provides many of the ranges for xenobiotic toxins so a clinician can identify a patient's current exposure and toxic load compared to the national averages and monitor the effectiveness of prescribed treatments.

Paediatric environmental health speciality units in Europe: integrating a missing element into medical care.

Paediatricians are in an excellent position to identify children with environmental risk, to advise their parents about the best way of reducing or preventing such risks, and to recommend actions to the responsible politicians involved. Paediatric environmental health speciality units (PEHSU) can help to qualify and support paediatricians in this task. PEHSU is defined as a unit within a paediatric hospital or clinic that is able to recognize, assess, and prevent environment-related health risks, to help other paediatric specialists in the management of such diseases in children, as well as to provide education, training, and research, putting emphasis on thorough and adequate establishment of paediatric environmental histories (PEHis) and to the application of the precautionary principle. Although activities and services provided by each PEHSU would differ depending on the centre or community where it is located, all should include training, research, medical care and community and school health.

American College of Occupational and Environmental Medicine (ACOEM): a professional association in service to industry.

The American College of Occupational and Environmental Medicine (ACOEM) is a professional association that represents the interests of its company-employed physician members. Fifty years ago the ACOEM began to assert itself in the legislative arena as an advocate of limited regulation and enforcement of occupational health and safety standards and laws, and environmental protection. Today the ACOEM provides a legitimizing professional association for company doctors, and continues to provide a vehicle to advance the agendas of their corporate sponsors. Company doctors in ACOEM recently blocked attempts to have the organization take a stand on global warming. Company doctors employed by the petrochemical industry even blocked the ACOEM from taking a position on particulate air pollution. Industry money and influence pervade every aspect of occupational and environmental medicine. The controlling influence of industry over the ACOEM physicians should cease. The conflict of interests inherent in the practice of occupational and environmental medicine is not resolved by the ineffectual efforts of the ACOEM to establish a pretentious code of conduct. The conflicted interests within the ACOEM have become too deeply embedded to be resolved by merely a self-governing code of conduct. The specialty practice of occupational and environmental medicine has the opportunity and obligation to join the public health movement. If it does, the ACOEM will have no further purpose as it exists, and specialists in occupational and environmental medicine will meet with and be represented by public health associations. This paper chronicles the history of occupational medicine and industry physicians as influenced and even controlled by corporate leaders.

Assessment of feminization of male fish in English rivers by the Environment Agency of England and Wales.

In recent years there has been considerable concern over the ability of substances discharged into the environment to disrupt the normal endocrine function of wildlife. In particular, the apparent widespread feminization of male fish in rivers has received significant attention from regulators in the United Kingdom, the United States, Europe, and Japan. The U.K. and European epidemiological data sets have demonstrated that the occurrence of feminized fish is associated with effluent discharges and that the incidence and severity is positively correlated with the proportion of treated sewage effluent in receiving waters. Although weakly estrogenic substances may contribute to the overall effect, studies have concluded that steroid estrogens are the principal and most potent estrogenic components of domestic sewage. Extensive laboratory data sets confirm that steroid estrogens are capable of eliciting the effects observed in wild fish at concentrations that have been measured in effluents and in the environment. Based on evaluation of the available information, the Environment Agency (England and Wales) has concluded that the weight of evidence for endocrine disruption in fish is sufficient to develop a risk management strategy for estrogenically active effluents that discharge to the aquatic environment.

Occupational and environmental medicine in the United States: A proposal to abolish workers' compensation and reestablish the public health model.

The workers' compensation model of occupational and environmental medicine should be converted to a public health model. Occupational and environmental medicine, as a part of the public health infrastructure,could play a much more substantive part in bringing about a national program to deal with occupational and environmental health. The workers' compensation insurance system could be discontinued at any time,but it will be vital to do so when national health insurance is adopted in the United States. Abolishing workers' compensation would remove the perverse incentives that currently undermine the practice of occupational medicine. Medical care for workers should be provided by health care professionals who are not subject to influence by employers or insurers. Eligibility for benefits should not be determined by health and safety professionals. Wage-replacement benefits for workers should be determined by guidelines established by government and industry that prevent manipulation of health and safety professionals by employers and insurers. A nationwide comprehensive system to track work-related injury and illness, superior to the current reliance on records provided by employers and collated by government agencies, should be adopted. When unusually high rates of injuries, illnesses,and fatalities occur, government inspectors ought to respond and regulate the industry accordingly. Occupational health and safety professional strained in public health can and should participate in these activities, but not when they are in the employ of industry or insurers.

An overview of the Institute of Naval Medicine.

In the time allotted to this presentation I have only been able to provide a brief outline of the type of work undertaken by INM. However, I hope I have been able to demonstrate that INM is indeed living up to its Mission Statement and motto 'e mari ad salutum'.

Implementation of a novel occupational and environmental medicine specialty teleconsultation service: the VHA experience.

OBJECTIVE: Occupational and environmental medicine (OEM) physician specialty practices continue to grow in scope and intensity across the Veterans Health Administration. This study characterizes the implementation of a novel, nationwide telemedicine program that provides OEM specialty consultation to providers across the Veterans Health Administration. METHODS: We examined provider requests and specialist responses for a 6-month pilot from May to October 2013. Characteristics of consult users, determinants of case complexity, and specific applications of OEM specialty expertise were identified. RESULTS: Over a 6-month period, employee occupational health providers consulted the OEM telemedicine pilot a total of 65 times. Employee occupational health providers without formal training repeatedly identified complex cases related to work and disability. CONCLUSIONS: The program has created a new system management solution to deliver expert, in-depth consultation and real-time provider education in OEM.

Commentary on the contributions and future role of occupational exposure science in a vision and strategy for the discipline of exposure science.

Exposure science is a holistic concept without prejudice to exposure source. Traditionally, measurements aimed at mitigating environmental exposures have not included exposures in the workplace, instead considering such exposures to be an internal affair between workers and their employers. Similarly, occupational (or industrial) hygiene has not typically accounted for environmental contributions to poor health at work. Many persons spend a significant amount of their lifetime in the workplace, where they maybe exposed to more numerous chemicals at higher levels than elsewhere in their environment. In addition, workplace chemical exposures and other exogenous stressors may increase epigenetic and germline modifications that are passed on to future generations. We provide a brief history of the development of exposure science from its roots in the assessment of workplace exposures, including an appendix where we detail current resources for education and training in exposure science offered through occupational hygiene organizations. We describe existing successful collaborations between occupational and environmental practitioners in the field of exposure science, which may serve as a model for future interactions. Finally, we provide an integrated vision for the field of exposure science, emphasizing interagency collaboration, the need for complete exposure information in epidemiological studies, and the importance of integrating occupational, environmental, and residential assessments. Our goal is to encourage communication and spur additional collaboration between the fields of occupational and environmental exposure assessment. Providing a more comprehensive approach to exposure science is critical to the study of the "exposome", which conceptualizes the totality of exposures throughout a person's life, not only chemical, but also from diet, stress, drugs, infection, and so on, and the individual response.

What is the strategic value of occupational and environmental medicine? Observations from the United States and Australia.

The world of work is changing rapidly. Occupational health and safety and environmental health increasingly are seen as a joint product with goods and services, requiring line-management responsibility. This new specialty is encouraged to be strategic rather than tactical to optimize its value in the core business of industry-related medical needs. Because employers, governments, and workers bear major costs, they have a strategic interest in outcomes. Strategic opportunities exist for reduction of the impact of occupational injury and disease; stewardship of the environment, product, and process; the reduction of non-occupational health care costs; for having occupational and environmental health and safety follow best business practices and be prominent in the leadership of change; for optimizing human relations/labor policies and practices; and for meeting regulatory requirements. The strategic position of the specialty can be strengthened through discussion, dialogue and vision development, role definition, establishment and use of performance indicators, improved career structures and training, and a proactive approach to qualify initiatives, research, marketing, and strategic alliances.

Expanding the specialty of occupational and environmental medicine: the role of the chief health officer. The Sappington Lecture.

Passage of the Occupational Safety and Health Act in 1971 represented a major milestone for occupational and environmental medicine. Creation of the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) flowed directly from the legislation, and the specialty of occupational medicine entered a new era. As the 25th anniversaries of OSHA and NIOSH are celebrated, consideration of the future of the specialty of occupational and environmental medicine seems timely. In this lecture, an expanded role for the specialty is proposed, based on an analysis of the forces shaping the practice of public health and the opportunities that these forces present. This analysis suggests considering the concept of a "Chief Health Officer" serving the broad health needs of the workplace.
