The Evolving Role of Dental Responders on Interprofessional Emergency Response Teams.

Disaster and pandemic response events require an interprofessional team of health care responders to organize and work together in high-pressure, time-critical situations. Civilian oral health care professionals have traditionally been limited to forensic identification of human remains. However, after the bombing of the Twin Towers in New York, federal agencies realized that dentists can play significant roles in disaster and immunization response, especially on interprofessional responder teams. Several states have begun to incorporate dentists into the first responder community. This article discusses the roles of dental responders and highlights legislative advancements and advocacy efforts supporting the dental responder.

Just-in-time training of dental responders in a simulated pandemic immunization response exercise.

ABSTRACT OBJECTIVE: The reauthorization of the Pandemic and All-Hazards Preparedness Act in 2013 incorporated the dental profession and dental professionals into the federal legislation governing public health response to pandemics and all-hazard situations. Work is now necessary to expand the processes needed to incorporate and train oral health care professionals into pandemic and all-hazard response events. METHODS: A just-in-time (JIT) training exercise and immunization drill using an ex vivo porcine model system was conducted to demonstrate the rapidity to which dental professionals can respond to a pandemic influenza scenario. Medical history documentation, vaccination procedures, and patient throughput and error rates of 15 dental responders were evaluated by trained nursing staff and emergency response personnel. RESULTS: The average throughput (22.33/hr) and medical error rates (7 of 335; 2.08%) of the dental responders were similar to those found in analogous influenza mass vaccination clinics previously conducted using certified public health nurses. CONCLUSIONS: The dental responder immunization drill validated the capacity and capability of dental professionals to function as a valuable immunization resource. The ex vivo porcine model system used for JIT training can serve as a simple and inexpensive training tool to update pandemic responders' immunization techniques and procedures supporting inoculation protocols.

Photodynamic therapy: occupational hazards and preventative recommendations for clinical administration by healthcare providers.

OBJECTIVE: Photodynamic therapy (PDT) as a medical treatment for cancers is an increasing practice in clinical settings, as new photosensitizing chemicals and light source technologies are developed and applied. PDT involves dosing patients with photosensitizing drugs, and then exposing them to light using a directed energy device in order to manifest a therapeutic effect. Healthcare professionals providing PDT should be aware of potential occupational health and safety hazards posed by these treatment devices and photosensitizing agents administered to patients. MATERIALS AND METHODS: Here we outline and identify pertinent health and safety considerations to be taken by healthcare staff during PDT procedures. RESULTS: Physical hazards (for example, non-ionizing radiation generated by the light-emitting device, with potential for skin and eye exposure) and chemical hazards (including the photosensitizing agents administered to patients that have the potential for exposure via skin, subcutaneous, ingestion, or inhalation routes) must be considered for safe use of PDT by the healthcare professional. CONCLUSIONS: Engineering, administrative, and personal protective equipment controls are recommendations for the safe use and handling of PDT agents and light-emitting technologies.

Application of immunohistochemical staining to detect antigen destruction as a measure of tissue damage.

Electrocautery and directed energy devices (DEDs) such as lasers, which are used in surgery, result in tissue damage that cannot be readily detected by traditional histological methods, such as hematoxylin and eosin staining. Alternative staining methods, including 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) to stain live tissue, have been reported. Despite providing superior detection of damaged tissue relative to the hematoxylin and eosin (H&E) method, the MTT method possesses a number of drawbacks, most notably that it must be carried out on live tissue samples. Herein, we report the development of a novel staining method, "antigen destruction immunohistochemistry" (ADI), which can be carried out on paraffin-embedded tissue. The ADI method takes advantage of epitope loss to define the area of tissue damage and provides many of the benefits of live tissue MTT staining without the drawbacks inherent to that method. In addition, the authors provide data to support the use of antibodies directed at a number of gene products for use in animal tissue for which there are no species-specific antibodies commercially available, as well as an example of a species-specific direct antibody. Data are provided that support the use of this method in many tissue models, as well as evidence that ADI is comparable to the live tissue MTT method.

Natural products and traditional medicine: turning on a paradigm.

Paradigm shifts in the strategies and the sciences that would enhance the quality, safety, and efficacy of traditional medicines and dietary supplements in global health care are discussed. Some of the challenges facing traditional medicine in health care are described, and the importance of defining clear goals and directions for the information systems, botany, chemistry, and biology related to plants and health care, including for drug discovery and quality control, is indicated.

An assessment of the occupational hazards related to medical lasers.

OBJECTIVE: Occupational hazards associated with medical laser applications remain poorly understood and uncharacterized. METHODS: A literature search was performed using PubMed, and all articles relevant to beam and nonbeam medical laser hazards were reviewed. The Rockwell Laser Industries Laser Accident Database was searched for medical laser injuries and abstracted. RESULTS: Eye injuries, skin burns, injuries related to the onset of fires, and electric shock have been reported in relation to medical laser use. It is probable that both acute and chronic health effects have been experienced by medical personnel as the result of exposure to laser generated air contaminants. CONCLUSIONS: Because of the clinical benefits they provide, the growth of laser technologies and applications are anticipated to result in an increase in the number and type of medical personnel with future exposure to laser hazards.

Handheld directed energy sensor for environmental monitoring and clinician safety.

INTRODUCTION: Directed energy (DE) research and development is generating more powerful portable devices designed to support operational, environmental, clinical, point detection, and remote-sensing applications. These same DE devices present potential for injury, thereby impacting medical operations. The environmental surveillance and clinical communities require handheld sensor platforms that afford preemptive detection and monitoring of potentially hazardous exposures to DE and other electromagnetic (EM) frequencies. METHODS: A personal digital assistant (PDA) was interfaced with a wavelength sensor board via a multifunction data acquisition card to passively detect wavelengths in the 480-950 nm range. A 9V DC battery coupled to a voltage up-converter with a manual ON/OFF switch powered the sensor board. The sensor board was integrated with a standard operating system-based PDA. Graphical programming software integrated the data acquisition card with the PDA. RESULTS: The DE wavelength sensor/PDA platform detected and relayed laser radiation information from 480 to 950 nm ranges, with graphical data output to the PDA screen. DISCUSSION: This project demonstrated the technical ability to detect anthropogenic DE frequency signatures using a handheld, battery-driven DE sensor platform. Laboratory and field assessment studies are underway to validate operational applications. This DE-sensing prototype is designed explicitly for DE medical measurement and signatures intelligence (MED MASINT) to meet the protection needs of environmental and clinical operators.

Disaster medicine training survey results for dental health care providers in Illinois.

BACKGROUND: Ongoing vigilance by governments, public health agencies and health care professionals monitoring potential epidemic and pandemic outbreaks, terrorist threats and ever-present natural disasters requires the continuous evolution of comprehensive disaster response plans and teams, which include the integration of oral health care professionals. METHODS: The authors conducted a study in which oral health care professionals assessed their training in the American Medical Association's (AMA's) National Disaster Life Support (NDLS) courses. At the conclusion of each instructional session, the authors asked participants to complete an anonymous course evaluation form to report their impressions of the training activity. The authors included in the analysis those evaluations associated with sessions attended almost exclusively by dentists and hygienists. RESULTS: The authors derived descriptive statistics from the selected course evaluations. Overall, oral health care professionals believed that the Core Disaster Life Support (CDLS) and Basic Disaster Life Support (BDLS) courses were of great educational value, rating course impact at 9.50 and 9.29, respectively, on a scale from 1 to 10. CONCLUSIONS: Statistical evaluation instruments reveal satisfaction with the all-hazards awareness training received through the AMA's NDLS disaster medicine training curriculum. Licensed oral health care professionals in Illinois accepted the utility and merits of, and benefited from, the four-hour CDLS and eight-hour BDLS certification programs. Practice Implications. Dental professionals in Illinois require minimal additional training for dental emergency responder duties. The AMA's NDLS curriculum provides effective preparation for dental professionals.

Survey of medical ethnobotanicals for dental and oral medicine conditions and pathologies.

Ethnomedical questionnaires were distributed in Chicago, Costa Rica, and Colombia to identify the most common over-the-counter (OTC) plant or plant-based products advocated for treating oral pain, ulcerative conditions, and cancer within these locations. Over 100 plants or plant-based herbal preparations and commercial products, purchased from local botanical markets and pharmacies, were advocated for the treatment of oral medicine conditions. Locally familiar and common language names were attributed to the plant products at the time of purchase. Plant products or plant-based commercial products containing plant-based essential oils, anesthetic constituents, and or chemical compounds recommended as OTC oral medicine preparations were systematized, tabulated, and correlated with the published phytotherapeutic literature. Though pharmacognostic research is available for some of the species collected, further ethnographic research is needed to correlate common names with the accurate taxonomic identification for each plant species. Furthermore, epidemiological research is needed to verify the use and standardized dosage for OTC ethnomedicine preparations for oral medicine conditions. Pharmacognostic research and clinical trails which can verify taxonomy, dose, safety, active principles, and efficacy of these OTC oral medicine products must be enhanced in order to verify the claimed validity in contemporary, global, oral medicine practice.

The dental emergency responder: Expanding the scope of dental practice.

BACKGROUND: Natural disasters, the potential for terrorism and weapons-of-mass-destruction events occurring within the continental United States necessitate that all licensed health care providers understand the National Incident Management System and be able to contribute to inoculation, mass casualty assistance and triage care of the populace. CONCLUSIONS: Health care and political leaders constantly revise "all hazard" response plans, using the available health care assets that local, state and federal agencies bring to emergency events. Illinois Public Act 49-409 modifies the scope of dental practice within Illinois to allow for a dental emergency responder (DER). PRACTICE IMPLICATIONS: The DER is a dentist or dental hygienist "acting within the bounds of his or her license when providing care during a declared local, state or national emergency."
