Analysis of workplace injuries in a dental school environment.

Workplace injuries at the University of Queensland Dental School during the period 1992-1994 were assessed to determine their incidence, and the associated indirect costs, causal factors, and appropriate preventive strategies. Overall, dental chairside assistants experienced a higher incidence of injuries than students both on a per worker and per time basis. Of the injuries with a low risk of cross-infection, burns and scalds from sterilizing equipment, and eye injuries in laboratories were the most common. This emphasizes the importance of wearing appropriate protective equipment in areas outside the treatment zone, and the need for signage and education. Common causes of sharps injuries were burs left in handpieces, two-handed needle recapping, and cleaning of probes in the sterilizing room. Changes to techniques and equipment would prevent such incidents. A range of factors which contribute to the calculation of indirect costs following injuries in the dental workplace are identified.

Healthy People 2010--vision objectives for the nation.

BACKGROUND: In January 2000, the U.S. Department of Health and Human Services released new national health goals and objectives in a report entitled Healthy People 2010. This national report includes specific objectives for improving the vision of people in the United States during the 2000-2010 decade through prevention, early detection, treatment, and rehabilitation. The vision objectives, along with other health objectives, are designed to help the nation achieve two major outcomes: (1) increase the quality and years of healthy life and (2) eliminate health disparities among different groups. These health objectives will strongly influence many health care programs and the provision of health care through laws, regulations, reimbursements, and clinical guidelines enacted by federal and state agencies. PURPOSE: The purpose of this article is to inform optometrists about the new Healthy People 2010 vision objectives. METHODS: A summary of the Healthy People process for developing the objectives--and the specific vision objectives--is provided. These objectives address many important areas, including: regular dilated eye examinations; vision screening for preschool children; uncorrected visual impairment due to refractive errors; blindness and visual impairment in children and adolescents; visual impairment due to diabetic retinopathy, glaucoma, and cataracts; occupational eye injury; the use of personal protective eye wear in recreational activities and hazardous situations around the home; and the use of vision rehabilitation services and adaptive devices by people with visual impairments. CONCLUSION: These new national health goals and objectives will impact optometrists. Therefore, it is important that optometrists understand these objectives and actively work to help implement them at the national, state, and local levels. By doing this, they can help provide the services needed to reduce visual impairments and improve the vision of people in their communities.

A monitoring study of workers handling pesticides in warehouses and godowns.

Monitoring observations made on 60 operators involved in pesticide application work in godowns and warehouses and 60 matched control workers are reported. Occupational exposure history and medical history are noted. Biochemical investigations, plasma and RBC cholinesterase estimations are included along with medical examination of the workers. Workers were found to be mostly exposed to Celphos, DDVP, Malathion, Pyrethrum, etc, and the use of protective devices were very limited. Cases of significant reduction in plasma and RBC cholinesterase activity were found. Frequency of symptoms like dizziness, headache, lachrymation, burning sensation in eyes, nausea and anorexia, etc, were much more in the exposed workers. No cases of clinical poisoning attributable to occupational exposure to pesticides were reported by the workers.

AlphaCor: Clinical outcomes.

PURPOSE: To study the outcomes of AlphaCor implantation. METHODS: : The AlphaCor artificial cornea is indicated for corneal blindness not treatable by donor grafting. Prospective preoperative and follow-up data were collected. Data were evaluated using SPSS for statistical analysis of outcomes, trends, and associations. RESULTS: This report includes data returned through February 28, 2006, for all 322 devices implanted, with mean follow-up in situ of 15.5 months and a maximum of 7.4 years. The probability of AlphaCor retention at 6 months and 1 and 2 years for protocol cases was 92%, 80%, and 62%, respectively, and off-label cases were at higher risk (P = 0.010), as were cases not prescribed medroxyprogesterone (MPG; P = 0.001). Currently, the most common complications were stromal melting, fibrous reclosure of the posterior lamellar opening, and white intraoptic deposits, with incidences in 2005 of 11.4%, 5.1%, and 2.6%, respectively. MPG seems to protect against melts, and eyes with a history of herpetic keratitis were not at increased risk. A history of glaucoma or the presence of tubes did not affect device retention. Complications culminated in loss of an eye in 1.3%. Mean preoperative visual acuity (VA) was hand movements. The VA achieved postoperatively (light perception to 20/20) was affected by previous pathology and postoperative course, with a mean improvement of 2 lines. CONCLUSION: AlphaCor provides a treatment option where a donor tissue graft would not succeed in severe corneal conditions, while being reversible to a donor graft in the event of complications for anatomic integrity. Surgical technique and adjunctive therapies are evolving with experience. Continued data collection is important for a fuller understanding of AlphaCor's role.

Ocular trauma in Turkey: a 2-year prospective study.

This 2-year prospective study was conducted to identify those at risk for ophthalmologic emergencies, to define the risk factors and reasons for eye injuries, to analyze treatment options, and to compare findings with those of previous studies. A total of 203 patients (74% male, mean age 27.3+/-13.9 y, 51% right eye injuries, 44% left eye injuries, 5% bilateral injuries) with injury to 208 eyes who presented to the emergency department for treatment were included in this study. All patients were evaluated by an ophthalmologist, who completed a formal questionnaire. Information recorded included demographic data, details of the eye injury, whether eye protection was used, and the type, location, and mechanism of injury to the eye. Mechanism of injury was categorized as blunt, sharp, or a combination. The ophthalmologist reported the time that had passed between occurrence of injury and presentation for treatment. Each patient was examined by the ophthalmologist, and findings, diagnosis, and treatment were documented. Of treated patients, 93% were hospitalized, most of whom required surgical treatment. One hundred (48%) injuries were related to blunt trauma and 86 (41%) to sharp device trauma. Only 10 (4%) patients were wearing protective eyewear when injured. Ruptured globe was the most common diagnosis of hospitalized patients and the most frequent cause of this was corneal lesions; subconjunctival hemorrhage was the most common diagnosis among nonhospitalized patients. In this study, the leading cause of eye injury was workplace accidents, probably attributable to growing industrialization in the region. Ocular trauma continues to be an important health problem in Turkey. Investigators believe that with education about and use of proper eye protection, 90% of eye injuries could be prevented.

Environmental health hazards from high-powered, infrared, laser devices.

The potential health hazards associated with high-power laser systems are not limited to the direct beam. In addition to the obvious hazards of direct beam exposure of personnel, environmental problems may arise from electrically-energized equipment, excessive noise from the laser itself, and from hazardous fumes, gases, and vapors originating from components of the laser or from the target material.

A review of orthodontic face-bow injuries and safety equipment.

Reports of soft tissue injuries from orthodontic face-bows have continued to appear in the dental and medical publications since the American Association of Orthodontists reported problems in 1975. In 1994 the results of a preliminary survey of face-bow injuries of the orthodontic societies and dental schools in Europe recorded nine serious injuries. The results of a recent face-bow injury survey of orthodontic practitioners in the United Kingdom and Eire recorded 33. The relative effectiveness of current extraoral traction safety products is discussed in relation to the cause of these continuing injuries.

Early diagnosis of phosgene overexposure.

At the present time, the following parameters can be recommended for "early diagnosis" of phosgene overexposure: Phosgene indicator paper badges, to be worn by all persons involved in handling phosgene (these badges permit immediate estimation of the exposure dose in each individual case); Observation of the initial irritative symptoms of the eye and the upper respiratory tract after phosgene inhalation can provide a rough indication of the inhalation concentration and dose; X-ray photographs of the lungs make it possible to detect incipient toxic pulmonary edema at an early stage, during the clinical latent period. A number of additional parameters require further critical investigation.

[Evaluation of the X-ray exposure dosage during coronary cineangiography].

PURPOSE: To study the radiation doses during cardiac catheterization. PATIENTS AND METHODS: Thermoluminescents dosimeters were placed over a phantom's cardiac area, measuring both entrance and exit of the X-ray beam to check the absorbed dose. We could measure the doses in the examiner with dosimeters in frontal and hand's back regions. RESULTS: The average rate of exposure in the cinefilmstep increases in the 5.2 times the average rate measured in the fluoroscopy mode. The dose absorbed by the patient was of 114 mGy during a total of 20 min X-ray exposure time (e.g. 15 min of fluoroscopy and 1 min of film). Compared to the results obtained with the phantom's dose we have found a relative error of 20. Under the same exposure time we wave found a 0.68 mSv dose in the examiner's hands and a 0.40 mSv dose in his eyes. CONCLUSION: In this kind of procedure the examiner should have special concern as to observe the appropriate technical conditions besides having to make use of individual protection devices to minimize the radiation doses on his own behalf and behalf of his patient.
