Abstract
BACKGROUND In contrast to pharmaceutical manufacturers, compounding pharmacies adhere to different quality-control standards, which may increase the likelihood of undetected outbreaks. In 2005, the Centers for Disease Control and Prevention received reports of cases of Serratia marcescens bloodstream infection occurring in patients who underwent cardiac surgical procedures in Los Angeles, California, and in New Jersey. An investigation was initiated to determine whether there was a common underlying cause. METHODS A matched case-control study was conducted in Los Angeles. Case record review and environmental testing were conducted in New Jersey. The Centers for Disease Control and Prevention performed a multistate case-finding investigation; isolates were compared using pulsed-field gel electrophoresis analysis. RESULTS Nationally distributed magnesium sulfate solution (MgSO(4)) from compounding pharmacy X was the only significant risk factor for S. marcescens bloodstream infection (odds ratio, 6.4; 95% confidence interval, 1.1-38.3) among 6 Los Angeles case patients and 18 control subjects. Five New Jersey case patients received MgSO(4) from a single lot produced by compounding pharmacy X; culture of samples from open and unopened 50-mL bags in this lot yielded S. marcescens. Seven additional case patients from 3 different states were identified. Isolates from all 18 case patients and from samples of MgSO(4) demonstrated indistinguishable pulsed-field gel electrophoresis patterns. Compounding pharmacy X voluntarily recalled the product. Neither the pharmacy nor the US Food and Drug Administration could identify a source of contamination in their investigations of compounding pharmacy X. CONCLUSIONS A multistate outbreak of S. marcescens bloodstream infection was linked to contaminated MgSO(4) distributed nationally by a compounding pharmacy. Health care personnel should take into account the different quality standards and regulation of compounded parenteral medications distributed in large quantities during investigations of outbreaks of bloodstream infection.

Abstract
To describe state-level actions and policies during the 2004-2005 influenza vaccine shortage and determine whether these or other factors were related to vaccination coverage, we surveyed all state health departments (including the District of Columbia). We included 2004-2005 Behavioral Risk Factor Surveillance System data to examine whether state-level actions, policies, or other factors like vaccine supply were related to changes in vaccination coverage in adults aged > or = 65 years from the previous non-shortage year. We found that 96% (n = 49) of states reported adopting or recommending adherence to the initial national interim influenza vaccination recommendations. Of these, at some point during the season, 22% (n = 11) reported local public health agencies issued prioritization recommendations that differed from the state health department's guidance. Eighty percent (n = 41) initiated at least one emergency response activity and 43% (n = 22) referred to or implemented components of their pandemic influenza plans. In 35% (n = 18), emergency or executive orders were issued or legislative action occurred. In a multivariable linear regression model, the availability and use of practitioner contact lists and having a relatively high vaccine supply in early October 2004 were associated with smaller decreases in coverage for adults aged > or = 65 years from the previous non-shortage season (p = 0.003, r2 = 0.26). States over-whelmingly followed national vaccination prioritization guidelines and used a range of activities to manage the 2004-2005 vaccine shortage. The availability and use of practitioner contact lists and having a relatively high vaccine supply early in the season were associated with smaller decreases in coverage from the previous non-shortage season.

Abstract
CONTEXT Botulism is a potentially lethal paralytic disease caused primarily by toxins of the anaerobic, spore-forming bacterium Clostridium botulinum. Although botulinum toxin A is available by prescription for cosmetic and therapeutic use, no cases of botulism with detectable serum toxin have previously been attributed to cosmetic or therapeutic botulinum toxin injections. On November 27, 2004, 4 suspected botulism case-patients with a link to cosmetic botulinum toxin injections were reported to the Centers for Disease Control and Prevention. OBJECTIVE To investigate the clinical, epidemiological, and laboratory aspects of 4 suspected cases of iatrogenic botulism. DESIGN, SETTING, AND PATIENTS Case series on 4 botulism case-patients. MAIN OUTCOME MEASURES Clinical characteristics of the 4 case-patients, epidemiological associations, and mouse bioassay neutralization test results from case-patient specimens and a toxin sample. RESULTS Clinical characteristics of the 4 case-patients were consistent with those of naturally occurring botulism. All case-patients had been injected with a highly concentrated, unlicensed preparation of botulinum toxin A and may have received doses 2857 times the estimated human lethal dose by injection. Pretreatment serum toxin levels in 3 of the 4 case-patients were equivalent to 21 to 43 times the estimated human lethal dose; pretreatment serum from the fourth epidemiologically linked case-patient was not available. A 100-microg vial of toxin taken from the same manufacturer's lot as toxin administered to the case-patients contained a toxin amount sufficient to kill approximately 14,286 adults by injection if disseminated evenly. CONCLUSIONS These laboratory-confirmed cases of botulism demonstrate that clinical use of unlicensed botulinum toxin A can result in severe, life-threatening illness. Further education and regulation are needed to prevent the inappropriate marketing, sale, and clinical use of unlicensed botulinum toxin products.

Abstract
AIM To assess lung involvement and the association of demographic and psychosocial factors with respiratory health in 736 persons with sarcoidosis at enrollment in A Case Control Etiologic Study of Sarcoidosis (ACCESS). METHODS 736 patients with biopsy diagnosis of sarcoidosis within 6 months of enrollment were studied at 10 US centers. Lung involvement was evaluated by chest radiography, spirometry and dyspnea questionnaire. Demographics, number of involved extrathoracic organ systems, comorbidities, and health-related quality of life (HRQL) were assessed. RESULTS 95% of patients had lung involvement. 8% were Scadding Stage 0, 40% I, 37% II, 10% III, and 5% IV 51% reported dyspnea. Increasing radiographic lung stage was associated with decreasing Forced Vital Capacity (FVC) (p < 0.01). Patients with higher stages had more airways obstruction and dyspnea. 46% of cases and 27% of controls had Center for Epidemiologic Studies Depression Scale (CES-D) scores of 9 or greater, (p < 0.001). Age > or = 40, African-American race, body mass index > or = 30kg/m2, and CES-D scores > 9 were associated with decreased FVC and greater dyspnea. Impaired spirometry and greater dyspnea were associated with poorer quality of life. CONCLUSION A "global" approach to the sarcoidosis patient, including careful assessment of dyspnea and health related quality of life, as well as of lung function and radiographic changes, and any extrathoracic involvement, is important, not only in management of the individual patient, but should also prove beneficial in assessing outcomes in clinical trials in the future.

Abstract
PURPOSE During 2003, the New Jersey Department of Health and Senior Services, in collaboration with other agencies, began planning and implementing voluntary smallpox vaccination clinics. METHODS Surveys were distributed to all vaccinees, hospital bioterrorism coordinators, and local health departments to assess clinic experiences. RESULTS During January-July 2003, 23 clinics were conducted with more than 1,000 participants. Of 670 persons vaccinated, 529 (79%) completed surveys. We received 65 surveys from 68 (77%) of 84 hospitals, and 25 responses from 22 regional health agencies. CONCLUSIONS Vaccination is one component of preparedness; future initiatives must incorporate multiagency collaboration and developing public health infrastructure.

Abstract
Past research suggests that environmental factors may be associated with sarcoidosis risk. We conducted a case control study to test a priori hypotheses that environmental and occupational exposures are associated with sarcoidosis. Ten centers recruited 706 newly diagnosed patients with sarcoidosis and an equal number of age-, race-, and sex-matched control subjects. Interviewers administered questionnaires containing questions regarding occupational and nonoccupational exposures that we assessed in univariable and multivariable analyses. We observed positive associations between sarcoidosis and specific occupations (e.g., agricultural employment, odds ratio [OR] 1.46, confidence interval [CI] 1.13-1.89), exposures (e.g., insecticides at work, OR 1.52, CI 1.14-2.04, and work environments with mold/mildew exposures [environments with possible exposures to microbial bioaerosols], OR 1.61, CI 1.13-2.31). A history of ever smoking cigarettes was less frequent among cases than control subjects (OR 0.62, CI 0.50-0.77). In multivariable modeling, we observed elevated ORs for work in areas with musty odors (OR 1.62, CI 1.24-2.11) and with occupational exposure to insecticides (OR 1.61, CI 1.13-2.28), and a decreased OR related to ever smoking cigarettes (OR 0.65, CI 0.51-0.82). The study did not identify a single, predominant cause of sarcoidosis. We identified several exposures associated with sarcoidosis risk, including insecticides, agricultural employment, and microbial bioaerosols.

Abstract
The DHSS and federal agencies have expanded their surveillance efforts to improve existing methods of reporting notifiable communicable diseases and to include additional data sources that might provide a more comprehensive view of disease activity in New Jersey. Currently, the DHSS is evaluating these efforts and recognizes several issues that need to be addressed, including: assessment of the timeliness, completeness, and accuracy of surveillance data; validation of surveillance data through comparison with hospital uniform billing data; characterization of the sensitivity of alerts through examination of reasons for identified aberrations in disease activity; evaluation of DHSS staffs and LINCS epidemiologists' follow-up efforts in response to alerts; evaluation of cumulative data trends to determine patterns in baseline disease activity (e.g., variations in disease activity attributed to seasonality); development of methods to integrate data from all surveillance efforts to provide timely, comprehensive, and coordinated summaries of disease activity and to distribute these summaries regularly to all New Jersey public health partners to better inform public health and clinical management; and development of a coordinated multi-agency response plan in conjunction with adjacent states. Though the DHSS hopes that these surveillance efforts will contribute to the early detection of sentinel events that might represent possible bioterrorist or emerging infectious disease threats, the DHSS will also need to engage the medical community more fully in surveillance activities. In previous experiences, astute clinicians were responsible for the identification of the first cases of West Nile virus, anthrax, and SARS. Therefore, to further ensure the success of its surveillance efforts, the DHSS will also need to continue educating clinicians about its surveillance activities and the importance of timely reporting of patients with illness patterns that might suggest an unusual infectious disease outbreak associated with bioterrorism or emerging infectious diseases.

An outbreak of multidrug-resistant Salmonellaenterica serotype Typhimurium infections occurred in Pennsylvania and New Jersey. A case-control study implicated pasteurized milk from a dairy, and an inspection indicated the potential for contamination after pasteurization. Dairy cattle are the likely reservoir, and milk may be an important vehicle of Salmonella transmission to humans.

Abstract
CONTEXT Little is known about potential long-term health effects of bioterrorism-related Bacillus anthracis infection. OBJECTIVE To describe the relationship between anthrax infection and persistent somatic symptoms among adults surviving bioterrorism-related anthrax disease approximately 1 year after illness onset in 2001. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional study of 15 of 16 adult survivors from September through December 2002 using a clinical interview, a medical review-of-system questionnaire, 2 standardized self-administered questionnaires, and a review of available medical records. MAIN OUTCOME MEASURES Health complaints summarized by the body system affected and by symptom categories; psychological distress measured by the Revised 90-Item Symptom Checklist; and health-related quality-of-life indices by the Medical Outcomes Study 36-Item Short-Form Health Survey (version 2). RESULTS The anthrax survivors reported symptoms affecting multiple body systems, significantly greater overall psychological distress (P<.001), and significantly reduced health-related quality-of-life indices compared with US referent populations. Eight survivors (53%) had not returned to work since their infection. Comparing disease manifestations, inhalational survivors reported significantly lower overall physical health than cutaneous survivors (mean scores, 30 vs 41; P =.02). Available medical records could not explain the persisting health complaints. CONCLUSION The anthrax survivors continued to report significant health problems and poor life adjustment 1 year after onset of bioterrorism-related anthrax disease.

Abstract
OBJECTIVE To characterize risk factors for invasive pneumococcal infection in a nursing home outbreak. DESIGN Outbreak investigation, case-control study. SETTING A 114-bed nursing home in New Jersey. PARTICIPANTS Case-patients were nursing home residents hospitalized with febrile respiratory illness and radiographic findings consistent with pneumonia, and either sputum specimens positive for diplococci or blood cultures positive for Streptococcus pneumoniae, with illness onset during April 3-24, 2001. Control-patients were selected randomly from remaining residents without respiratory symptoms. METHODS Chart reviews were performed for case-patients and control-patients. Serotyping and susceptibility testing were performed on S. pneumoniae isolates. Long-term-care facilities (LTCFs) were surveyed to assess compliance with a state regulation mandating pneumococcal vaccination of residents 65 years and older. RESULTS Nine case-patients were identified, with a median age of 86 years (range, 78 to 100 years). The median age of control-patients was 86 years (range, 58 to 95 years). No case-patients versus 9 (50%) control-patients received pneumococcal vaccine before the outbreak (OR, 0; CI95, 0-0.7). Recent antibiotic use, pneumonia history, and physical functioning were not associated with illness. Illness attack rate was 16% among all unvaccinated residents versus 0 among vaccinated residents. S. pneumoniae serotype 14, included in pneumococcal vaccine, was isolated from blood cultures of 7 case-patients. Of 361 LTCFs (42%) that replied to the survey, 28 (8%) were not complying with state immunization regulations. CONCLUSIONS This outbreak occurred in an LTCF with low vaccine coverage. Implementing standing order programs, enforcing regulations, documenting vaccinations, and providing education might increase coverage among nursing home residents.

Abstract
A bioterrorism attack using the United States postal system to deliver a hazardous biological agent to specific targets created multiple environmental and occupational exposure risks along the path of the anthrax-containing letters. On October 18, 2001, a suspected case of cutaneous anthrax was confirmed in a postal worker from the Trenton Processing and Distribution Center where at least four suspect letters were postmarked. Over the next three weeks, a team of investigators collected samples at 57 workplaces in New Jersey as part of a comprehensive environmental investigation to assess anthrax contamination as a result of this bioterrorist attack. A total of 1369 samples were collected with positive sample results found in two mail processing and distribution centers, six municipal post offices, and one private company. This large-scale epidemiological and public health investigation conducted by state and federal agencies included environmental evaluations utilizing general industrial hygiene principles. Issues of sampling strategy, methods, agency cooperation and communication, and site assessment coordination are discussed.

Abstract
A cohort of 215 sarcoidosis patients from the ACCESS study underwent a clinical evaluation at study enrollment and two years later. Approximately 80% of subjects had an improved or stable FVC, FEV1, chest radiograph determined by Scadding stage, and dyspnea scale. African-Americans had less improvement in FVC than Caucasians (p = 0.04). Patients with erythema nodosum at presentation were more likely to have improvement in the chest radiograph at two-year follow-up (p = 0.007). Patients with a lower annual family income were more likely to worsen with respect to dyspnea (p = 0.01) and more likely to have new organ involvement at two-year follow-up (p = 0.045). The development of new organ involvement over the two year follow-up period was more common in African-Americans compared to Caucasians (p = 0.002) and more likely in those with extrapulmonary involvement at study entry (p = 0.003). There was an excellent concordance between changes in FVC and FEV1 over the two-year period. However, changes in FVC alone were inadequate to describe the change in pulmonary status of the patients, as changes in chest radiographic findings or the level of dyspnea did often but not always move in the same direction as FVC. In conclusion, data from this heterogeneous United States sarcoidosis population indicate that sarcoidosis tends to improve or remain stable over two years in the majority of patients. Several factors associated with improved or worse outcome over two years were identified.

Abstract
In October 2001, the first inhalational anthrax case in the United States since 1976 was identified in a media company worker in Florida. A national investigation was initiated to identify additional cases and determine possible exposures to Bacillus anthracis. Surveillance was enhanced through health-care facilities, laboratories, and other means to identify cases, which were defined as clinically compatible illness with laboratory-confirmed B. anthracis infection. From October 4 to November 20, 2001, 22 cases of anthrax (11 inhalational, 11 cutaneous) were identified; 5 of the inhalational cases were fatal. Twenty (91%) case-patients were either mail handlers or were exposed to worksites where contaminated mail was processed or received. B. anthracis isolates from four powder-containing envelopes, 17 specimens from patients, and 106 environmental samples were indistinguishable by molecular subtyping. Illness and death occurred not only at targeted worksites, but also along the path of mail and in other settings. Continued vigilance for cases is needed among health-care providers and members of the public health and law enforcement communities.

Abstract
In October 2001, two inhalational anthrax and four cutaneous anthrax cases, resulting from the processing of Bacillus anthracis-containing envelopes at a New Jersey mail facility, were identified. Subsequently, we initiated stimulated passive hospital-based and enhanced passive surveillance for anthrax-compatible syndromes. From October 24 to December 17, 2001, hospitals reported 240,160 visits and 7,109 intensive-care unit admissions in the surveillance area (population 6.7 million persons). Following a change of reporting criteria on November 8, the average of possible inhalational anthrax reports decreased 83% from 18 to 3 per day; the proportion of reports requiring follow-up increased from 37% (105/286) to 41% (47/116). Clinical follow-up was conducted on 214 of 464 possible inhalational anthrax patients and 98 possible cutaneous anthrax patients; 49 had additional laboratory testing. No additional cases were identified. To verify the limited scope of the outbreak, surveillance was essential, though labor-intensive. The flexibility of the system allowed interim evaluation, thus improving surveillance efficiency.

Abstract
Despite reports of familial clustering of sarcoidosis, little empirical evidence exists that disease risk in family members of sarcoidosis cases is greater than that in the general population. To address this question, we estimated sarcoidosis familial relative risk using data on disease occurrence in 10,862 first- and 17,047 second-degree relatives of 706 age, sex, race, and geographically matched cases and controls who participated in the multicenter ACCESS (A Case-Control Etiology Study of Sarcoidosis) study from 1996 to 1999. Familial relative risk estimates were calculated using a logistic regression technique that accounted for the dependence between relatives. Sibs had the highest relative risk (odds ratio [OR] = 5.8; 95% confidence interval [CI] = 2.1-15.9), followed by avuncular relationships (OR = 5.7; 95% CI = 1.6-20.7), grandparents (OR = 5.2; 95% CI = 1.5-18.0), and then parents (OR = 3.8; 95% CI = 1.2-11.3). In a multivariate model fit to the parents and sibs data, the familial relative risk adjusted for age, sex, relative class, and shared environment was 4.7 (95% CI = 2.3-9.7). White cases had a markedly higher familial relative risk compared with African-American cases (18.0 versus 2.8; p = 0.098). In summary, a significant elevated risk of sarcoidosis was observed among first- and second-degree relatives of sarcoidosis cases compared with relatives of matched control subjects.

Abstract
Sarcoidosis may be affected by sex, race, and age. A Case Control Etiologic Study of Sarcoidosis (ACCESS) enrolled 736 patients with sarcoidosis within 6 mo of diagnosis from 10 clinical centers in the United States. Using the ACCESS sarcoidosis assessment system, we determined organ involvement for the whole group and for subgroups differentiated by sex, race, and age (less than 40 yr or 40 yr and older). The study population was heterogeneous in terms of race (53% white, 44% black), sex (64% female, 36% male), and age (46% < 40 yr old, 54% > or = 40 yr old). Women were more likely to have eye and neurologic involvement (chi(2) = 4.74, p < 0.05 and chi(2) = 4.60, p < 0.05 respectively), have erythema nodosum (chi(2) = 7.28, p < 0.01), and to be age 40 yr or over (chi(2) = 6.07, p < 0.02) whereas men were more likely to be hypercalcemic (chi(2) = 7.38, p < 0.01). Black subjects were more likely to have skin involvement other than erythema nodosum (chi(2) = 5.47, p < 0.05), and eye (chi(2) = 13.8, p < 0.0001), liver (chi(2) = 23.3, p < 0.0001), bone marrow (chi(2) = 18.8, p < 0.001), and extrathoracic lymph node involvement (chi(2) = 7.21, p < 0.01). We conclude that the initial presentation of sarcoidosis is related to sex, race, and age.

Abstract
This study assessed the utility of Poison Control Center data for identifying and describing occupational toxic exposures to youth and the associated health outcomes of such exposures. The authors reviewed 1997 data from the American Association of Poison Control Centers' Toxic Exposure Surveillance System for occupational exposures to persons 6 to 19 years old. In 1997, there were 3442 reported occupational exposure cases among 6- to 19-year-olds. Exposure cases included underage workers, exposure to multiple substances, continuous or repeated exposure to the offending substance, and exposures occurring in the home. Poison Control Centers provide unique and valuable information on toxic workplace exposures to youth. Child labor laws may be violated in many cases, and risks exist with respect to industrial work done in the home. Prospective studies with immediate follow-back are needed.

Abstract
Regional poison control centers (PCCs) were surveyed nationally to assess their policies and practices in handling work-related exposures. A 24-item survey was mailed to the executive directors of 44 American Association of Poison Control Centers' certified PCCs nationwide. The survey also requested permission to call the PCC to conduct a blinded role-playing exercise of a case of work-related trichloroethane exposure. Responses on the management questionnaire were compared with the actual responses provided by information specialists in the role-playing exercise. Seventy-five percent of PCCs completed the survey; 43% completed the telephone role-playing exercise. Survey respondents generally overestimated what they thought was routinely done to assess work-related calls, compared with what actually occurred at the time of the work-related call in the role-playing exercise. For example, 32% indicated that their PCC asked about the activities of nearby workers, but none of the PCC staff actually did so. Eighty-nine percent of the PCC executive directors surveyed thought that their staff routinely advised callers to notify their employer about work-related exposure concerns, but this occurred in only 11% of the calls. We concluded that PCCs' responses to work-related calls are inadequate. Given the public health impact of work-related calls, PCCs should develop, implement, and monitor written protocols to better address the public health issues of workplace poisonings.

Abstract
This study describes the extent of agreement in classification of chest radiographs using the International Labor Organization (ILO) classification among six readers from the United States and Canada. A set of 119 radiographs was created and read by three Canadian and three US readers. The two ratings of interest were profusion (scored from 0/- to 3/+) and pleural abnormalities consistent with pneumoconiosis (scored with the ILO system, then collapsed into a yes/no). We used a number of approaches to evaluate interreader agreement on profusion and pleural changes, determining concordance, observed agreement, kappa statistic, and a new measure to approximate sensitivity and specificity. This study found that five of six readers had good fair to good agreement for pleural findings and for profusion as a dichotomous variable (> or = 1/0 vs < or = 0/1) using the kappa statistic, while a sixth reader had poor agreement. We found that concordance, expressed as percent agreement, was higher for normal radiographs than for ones that showed disease, and describe the use of the kappa statistic to control for this finding. This analysis adds to the existing literature with the use of the kappa statistic, and by presenting a new measure for "underreading" and "overreading" tendencies.

Abstract
ALD affects a large segment of the population in the United States, both old and young, and men and women of all races and ethnicities. Many chronic diseases inevitably advance to a stage that results in significant respiratory impairment and disability. Although the causes of some of the diseases are known and the diseases may be preventable, the overall absolute burden of illness in the population is rising because of an enlarging population and newer therapeutic approaches. This is evident despite the lack of consistent and comparable data estimates for all diseases from national database resources. Where the data exist, it is evident that the cost related to the morbidity and mortality of these illnesses is substantial and consumes a significant proportion of health care expenditures. Both morbidity and mortality estimates, as well as cost estimates, are conservative and are likely underestimates of the true overall impact of ALD on the US economy.

Abstract
Occupational and environmental exposures cause substantial lung disease morbidity and mortality. A detailed exposure history is the key to detecting and treating these largely preventable illnesses and deaths. Components of an exposure history include details of the current and past work histories as well as of nonoccupational exposures. Identification of a sentinel health event requires a public health approach to the follow-up of affected individuals. This approach includes industrial hygiene sampling and monitoring, engineering and administrative controls, institution of proper work practices, education, and medical monitoring.

Abstract
OBJECTIVE The study goal was to assess the extent of workplace-related disease and injury among Social Security Disability Insurance applicants. METHODS A convenience sample of 240 consecutive applicants to the Pennsylvania Bureau of Disability Determination was studied to assess the prevalence of work-related disorders. An applicant had a work-related condition if there was a clear statement of a workplace illness or injury associated with the impairment, or if the applicant had worked at an occupation with a high likelihood of exposures known or suspected to contribute to the condition of interest. RESULTS Of the 240 applicants, 166 (69%) were awarded disability insurance benefits; a total of 27 (11%) had work-related conditions, including 14 of the 166 (8%) who were found to be disabled. Forty percent of the 27 had a disorder that was musculoskeletal in origin. Of 59 applicants with cancer, 10.2% had some work-related etiological component. Of an estimated 71,680 adult disability insurance applicants in Pennsylvania in 1990, 5134 new insurance beneficiaries had a projected occupationally related disability. CONCLUSIONS A substantial number of applicants for disability insurance benefits suffer from an impairment caused or exacerbated by prior workplace exposures. These individuals may serve as sentinel events for initiating follow-up surveillance and prevention activities.

Abstract
Sleep-disturbed breathing, which includes apneas, hypopneas, and oxygen desaturations, occurs in asymptomatic individuals and increases with age. Obstructive apnea is the most frequent type of respiratory disturbance documented by polysomonography, the gold standard test for assessing sleep-disturbed breathing. Many of the prevalence studies done to date have had one or more methodological weaknesses, including selection biases, varying definitions of obstructive sleep apnea, failure to distinguish types of apneas, failure to control for confounding variables, and small sample size. Although there is consensus on the definitions of sleep-disturbed breathing, the appropriate number of apneas and hypopneas for diagnosing clinically significant obstructive sleep apnea is uncertain. While the cutoff of five or more apneas and hypopneas per hour is historically considered abnormal, the origins of this number are vague, and the longevity of those who have this value on polysomnography is not necessarily reduced. This is particularly true among those without symptoms of obstructive sleep apnea syndrome, which include excessive daytime sleepiness, snoring, nocturnal awakenings, and morning headaches. Investigators should be careful to distinguish symptomatic study subjects from asymptomatic subjects, and to exclude central apneas in calculating their estimates. In addition, various studies have used different definitions of sleep apnea syndrome, making comparisons of point estimates difficult. It would be more appropriate for researchers to estimate morbidity and mortality indices with confidence intervals, using several different cutoff points. Subject selection in all studies should follow a two-stage sampling procedure. All subjects with symptoms compatible with obstructive sleep apnea syndrome and a subsample of asymptomatic individuals should be studied with all-night polysomnography. If portable monitoring is used, the validity and reproducibility of this diagnostic method should be assessed. Subjects with significant comorbidity should be excluded from prevalence studies. Factors that clearly increase the risk of sleep-disturbed breathing and obstructive sleep apnea and its related symptoms include age, structural abnormalities of the upper airway, sedatives and alcohol, and probably family history. Although endocrine changes such as growth hormone, thyroid hormone, and progesterone deficiency also have been suggested as risk factors for exacerbating obstructive sleep apnea syndrome, there is minimal epidemiologic evidence to support this. Case-control studies are recommended to assess the relation of endocrine factors to obstructive sleep apnea syndrome in a rigorous fashion. A limited number of mortality studies have suggested decreased survival in persons with the obstructive sleep apnea syndrome, possibly primarily due to vascular-related disease.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Elevator construction workers are exposed to asbestos dust during construction and refurbishment work on older buildings. We screened a cohort of workers, all with greater than 20 yr of employment in the industry, with clinical examinations, chest radiography ("B" reader interpretations), and routine spirometry. Twenty of the 91 workers (22%) had evidence of pleural disease, but none of them had an interstitial process consistent with asbestosis. Of those with pleural thickening, 15 had bilateral circumscribed plaques and five had unilateral plaque formation. There were no cases of diffuse pleural thickening, benign pleural effusions, or mesothelioma identified in our cohort. The difference in the mean body mass index of those with pleural abnormalities (29.18 +/- 3.95) and those without (27.7 +/- 3.86) was not statistically significant (p = 0.135). We conclude that elevator construction workers have an increased risk for the development of asbestos-related pleural disease.

Abstract
Computer based learning (CBL) is a recent educational innovation that may supplement the limited formal education typically offered to medical students in occupational health-related issues. The authors conducted a randomized trial among sophomores to evaluate a Macintosh-based application on occupational lung disease (OH-CBL). The program emphasizes interactive learning and skills practice through a case-based approach. Students taking an OH block in the Preventive Medicine course were assigned either to the OH-CBL or to the lecture group. 35 students completed the OH-CBL; 45 attended the lecture. Of four study-relevant multiple-choice questions, substantial differences were found in favor of the OH-CBL group over the lecture group on one question as well as on the study-relevant multiple choice total score. There was no difference on mean overall grade or on the three study-relevant essay items. The grade on study-relevant questions exhibited a weak relationship with microcomputer experience (r = .29, P = .04). Students' ratings of the CBL program using Likert scales were generally favorable. These findings suggest that CBL programs can be designed to be both acceptable to students and educationally effective. Each new program needs to be individually assessed to meet these standards. The authors identify several components of CBL that are necessary for successful implementation into a medical curriculum.

Abstract
Incinerator workers are exposed to many toxic compounds, most notably heavy metals. We evaluated medical and exposure monitoring data of an actively employed cohort of Philadelphia incinerator workers following an Agency for Toxic Substances and Disease Registry site survey and National Institute for Occupational Safety and Health (NIOSH) health hazard evaluation (HHE). Of the many airborne samples taken by NIOSH, only four of the personal breathing zone samples were above OSHA or ACGIH standards: one for lead, one for phosphorous, and two for total particulates. Because samples were taken during limited operations (only one of the two incinerators were operating), the results may underestimate historical exposures at this site. We limited our medical analysis to the 86 male workers who participated in the HHE out of the 105 active employees. The 86 employees were divided into potential high and low exposure groups based on a work site analysis done by an independent industrial hygienist. Eight individuals had at least one elevated biological index indicating exposure to a heavy metal. These elevations, however, were unrelated to the workers' exposure categories. Furthermore, no clinically significant mean blood or serum measurements were noted. Thirty-four percent of the workers had evidence of hypertension which increased the risk of significant proteinuria. Neither hypertension nor proteinuria were related to exposure group. Changes in pulmonary function related only to smoking status. Although there was some evidence of an increased risk of exposure to products of incinerator waste, we could not relate the few elevated biological tests to exposure classification. Additional studies are needed to assess the potential health effects of municipal waste incinerator by-products.

Abstract
A variety of state and federal data sources are used to estimate two critical components of the annual economic costs of occupational injuries and illnesses in Pennsylvania: foregone earnings of affected workers and medical costs. Foregone earnings costs resulting from occupational injuries and illnesses are estimated at between $1.22 billion and $2.02 billion in 1988. A number of potential adjustments to these estimates widen the range considerably. Estimates of medical costs range from $740 million to $797 million. Combining these two estimates gives total estimated costs of $1.96 billion to $2.82 billion.

Abstract
We followed up 73 of 372 calls to a Regional Poison Control Center (RPCC) that involved workplace disease/exposure(s); most other calls were not made by the workers. An average of 12 additional people per workplace were potentially exposed. Six of the 73 contacted a government agency for investigation of the hazard/illness. Twenty-five percent of callers were still exposed an average of seven months after the original call. The results indicate that poison control centers should develop a public health component to calls about possible workplace poisonings.

Abstract
Each year, poison control centers (PCCs) receive more than 25,000 calls related to workplace exposures to hazardous substances. Recent studies indicate that each caller may be a sentinel contact representing other exposed or ill workers. Although PCCs traditionally focus their follow-up efforts on the treatment of the index case alone, with minimal attention to the public health implications of other exposed or ill workers, PCCs could serve as a national surveillance system for occupational illnesses, a system with both passive and active attributes.

Abstract
We surveyed American and Canadian medical schools to assess the extent to which occupational health professionals provided services to their own institutions. Ninety-two of 155 schools (60 percent) responded to a mailed questionnaire. Forty-six (51 percent) of the respondents had an occupational health service distinct from an employee health service. Two thirds of the respondents provided occupational health services to business and industry. Such professionals based in nonclinical departments were more likely to provide educational and epidemiologic services for hospital employees than were professionals based in clinical departments. In those institutions with risk management, biohazards, or health and safety committees, less than one half of the occupational health professionals in those institutions were members of those committees. Five respondents felt that there were financial disincentives to providing occupational health services to their institution's employees. We conclude that academic-based occupational health professionals have inadequate input into the provision of such services at their own institutions.

Abstract
Exposure to hazardous chemicals often occurs in the workplace. Workers and health care providers may have little knowledge of the health effects of these substances. An algorithm was developed to outline a logical approach to toxicologic information retrieval. Printed material and information sources such as government agencies, manufacturers, unions, and poison control centers should be consulted as a first step. If additional information is needed, telecommunications systems provide access to online databases. Aspects of databases most likely to provide useful information on toxic exposures are described.

Abstract
The International Labour Office (ILO) classification of radiographs of pneumoconiosis is a standard means of assessing the presence or absence of pneumoconiosis in workers exposed to mineral dusts. Using this classification, 200 admission chest radiographs were reviewed on hospitalized patients in an urban university medical center to determine the prevalence and possible significance of "small opacities" in a population without known industrial exposure. Seventy-one men and 129 women were screened with the mean age of 44.2 years (range, 15-84). Thirty-six (18%) of the 200 patients had small opacities at profusion level 1/0 or greater, and this constituted the "positive radiographs" group. Twenty-two patients (11%) with positive radiographs had no documentable dust exposure or other specific medical etiology that would explain the presence of their lung opacities. The high prevalence of small opacities in "normal" older individuals has important implications in the assessment of patients with suspected pneumoconiosis.

Abstract
In recent years there has been increasing attention to the appropriate interpretation of a clinical study. One special concern has been the difficulty inherent in interpreting studies that were not statistically significant: Was the sample size sufficient to detect a clinically important effect if, in fact, it existed? This concern is further complicated because readers may have differing opinions of what size effect is clinically important. A pair of sample size nomograms has been developed, using common levels of statistical significance, to assist in this interpretation. The nomograms are intended to provide the clinician with a handy and easy-to-use reference for ascertaining whether an apparently negative study has a sample size adequate to detect reliably any difference between treatment groups that the clinician believes is clinically important. Examples are provided to show these principles and the use of the nomograms in interpreting negative studies.
