Assessment of potassium iodide (KI) distribution program among communities within the emergency planning zones (EPZ) of two nuclear power plants.

The primary objective of this study was to evaluate a joint state and local government-sponsored potassium iodide (KI) distribution program in New Jersey. This program is part of a radiological emergency response system for residents living within the Emergency Planning Zones (EPZs) of nuclear power facilities. KI pills and an informational fact sheet were distributed locally at six different public clinics in the summer of 2002. In this study, a mailed survey was developed, pilot tested, and sent to the general public to assess knowledge about KI use. The survey consisted of two groups of people, those who attended a KI distribution clinic and those that did not attend a clinic. There was a statistically significant difference in knowledge among the two groups of survey respondents regarding KI prophylaxis, with a mean of 46% of survey questions answered correctly by those who attended a clinic vs. 15% by those who did not attend. Certain questions were problematic for the public to answer correctly and included potential low compliance with government instructions for taking KI, confusion regarding where the public can obtain KI pills during an emergency, and the lack of awareness on the proper use of KI for children, pregnant women, and persons over the age of 40 y. Additional outreach in these specific areas is warranted. This study also found that there was a highly variable geographic pattern of homes that have a supply of KI pills, with some areas having 60% of the households supplied with pills from the clinic while other areas had as low as 1% of the homes supplied with KI pills.

Job and industry classifications associated with sarcoidosis in A Case-Control Etiologic Study of Sarcoidosis (ACCESS).

OBJECTIVES: To determine whether specific occupations and industries may be associated with sarcoidosis. METHODS: A Case Control Etiologic Study of Sarcoidosis (ACCESS) obtained occupational and environmental histories on 706 newly diagnosed sarcoidosis cases and matched controls. We used Standard Industrial Classification (SIC) and Standard Occupational Classification (SOC) to assess occupational contributions to sarcoidosis risk. RESULTS: Univariable analysis identified elevated risk of sarcoidosis for workers with industrial organic dust exposures, especially in Caucasian workers. Workers for suppliers of building materials, hardware, and gardening materials were at an increased risk of sarcoidosis as were educators. Work providing childcare was negatively associated with sarcoidosis risk. Jobs with metal dust or metal fume exposures were negatively associated with sarcoidosis risk, especially in Caucasian workers. CONCLUSIONS: In this study, we found that exposures in particular occupational settings may contribute to sarcoidosis risk.

Relationship of environmental exposures to the clinical phenotype of sarcoidosis.

STUDY OBJECTIVES: Sarcoidosis is a granulomatous disorder with heterogeneous clinical manifestations, which are potentially reflective of a syndrome with different etiologies leading to similar histologic findings. We examined the relationship between environmental and occupational exposures, and the clinical phenotype of sarcoidosis. DESIGN: We performed a cross-sectional study of incident sarcoidosis cases that had been identified by A Case Control Etiologic Study of Sarcoidosis. Subjects were categorized into the following two groups: (1) pulmonary-only disease; and (2) systemic disease (with or without pulmonary involvement). Logistic regression was used to examine the associations of candidate exposures with clinical phenotype. SETTING: Ten academic medical centers across the United States. PATIENTS: The current study included 718 subjects in whom sarcoidosis had been diagnosed within 6 months of study enrollment. Patients met the following criteria prior to enrollment: (1) tissue confirmation of noncaseating granulomas on tissue biopsy on one or more organs within 6 months of study enrollment with negative stains for acid-fast bacilli and fungus; (2) clinical signs or symptoms that were consistent with sarcoidosis; (3) no other obvious explanation for the granulomatous disease; and (4) age > 18 years. MEASUREMENTS AND RESULTS: Several exposures were associated with significantly less likelihood of having extrapulmonary disease in multivariate analysis, including agricultural organic dusts and wood burning. The effects of many of these exposures were significantly different in patients of different self-defined race. CONCLUSIONS: The differentiation of sarcoidosis subjects on the basis of clinical phenotypes suggests that these subgroups may have unique environmental exposure associations. Self-defined race may play a role in the determination of the effect of certain exposures on disease phenotypes.

Use of a state regulation for adult vaccination.

BACKGROUND: Influenza and pneumococcal disease are major causes of vaccine-preventable death among the elderly. In an effort to raise immunization rates, New Jersey in 1999 adopted a regulation requiring hospitals to offer pneumococcal and influenza vaccinations to all inpatients aged 65 and over. This study examined the effect of implementation strategies on immunization rates within hospitals in 2000 and 2001. METHODS: Hospital infection control directors were surveyed and random chart review was conducted from a stratified sample of hospitals. The infection control director's assessment of their institution's success was a major outcome measure. RESULTS: Relatively few respondents thought their hospital has been successful in implementing new immunization protocols. Approximately 67% responded that they did not think physicians agreed with the "scope and nature" of the regulation. Physician attitudes led the list of barriers to implementation cited by respondents. Chart review revealed moderate amounts of immunization assessment performed by nurses, but virtually no evidence of physicians' orders for immunization. CONCLUSIONS: Thus far, there is little evidence that the New Jersey regulation has resulted in a meaningful change in pneumococcal or influenza vaccination practices.

SARS and pregnancy: a case report.

We report a laboratory-confirmed case of severe acute respiratory syndrome (SARS) in a pregnant woman. Although the patient had respiratory failure, a healthy infant was subsequently delivered, and the mother is now well. There was no evidence of viral shedding at delivery. Antibodies to SARS virus were detected in cord blood and breast milk.

The critical role of pathology in the investigation of bioterrorism-related cutaneous anthrax.

Cutaneous anthrax is a rare zoonotic disease in the United States. The clinical diagnosis traditionally has been established by conventional microbiological methods, such as culture and gram staining. However, these methods often yield negative results when patients have received antibiotics. During the bioterrorism event of 2001, we applied two novel immunohistochemical assays that can detect Bacillus anthracis antigens in skin biopsy samples even after prolonged antibiotic treatment. These assays provided a highly sensitive and specific method for the diagnosis of cutaneous anthrax, and were critical in the early and rapid diagnosis of 8 of 11 cases of cutaneous anthrax during the outbreak investigation. Skin biopsies were obtained from 10 of these 11 cases, and histopathological findings included various degrees of ulceration, hemorrhage, edema, coagulative necrosis, perivascular inflammation, and vasculitis. Serology was also an important investigation tool, but the results required several weeks because of the need to test paired serum specimens. Other tests, including culture, special stains, and polymerase chain reaction assay, were less valuable in the diagnosis and epidemiological investigation of these cutaneous anthrax cases. This report underscores the critical role of pathology in investigating potential bioterrorism events and in guiding epidemiological studies, a role that was clearly demonstrated in 2001 when B. anthracis spores were intentionally released through the United States postal system.

Epidemiologic investigations of bioterrorism-related anthrax, New Jersey, 2001.

At least four Bacillus anthracis-containing envelopes destined for New York City and Washington, D.C. were processed at the Trenton Processing and Distribution Center (PDC) on September 18 and October 9, 2001. When cutaneous anthrax was confirmed in a Trenton postal worker, the PDC was closed. Four cutaneous and two inhalational anthrax cases were identified. Five patients were hospitalized; none died. Four were PDC employees; the others handled or received mail processed there. Onset dates occurred in two clusters following envelope processing at the PDC. The attack rate among the 170 employees present when the B. anthracis-containing letters were sorted on October 9 was 1.2%. Of 137 PDC environmental samples, 57 (42%) were positive. Five (10%) of 50 local post offices each yielded one positive sample. Cutaneous or inhalational anthrax developed in four postal employees at a facility where B. anthracis-containing letters were processed. Cross-contaminated mail or equipment was the likely source of infection in two other case-patients with cutaneous anthrax.

Hospital recruitment for the Smallpox Pre-Event Vaccination Program: experiences from Florida, Nebraska, New Jersey, and Tennessee, December 2002-June 2003.

The Smallpox Pre-Event Vaccination Program (SPVP) for public health and hospital-based health care workers began on January 24, 2003. This report summarizes efforts made by health officials in Florida, Nebraska, New Jersey, and Tennessee to facilitate the voluntary participation of acute care hospitals in the SPVP. Seven common characteristics contributed to the success of programs in these four states: (1) early planning, building on existing competencies, and state government support, (2) carrying the program forward on a planned timeline with experienced vaccination staff, (3) use of multifaceted training activities, (4) use of mock scenarios and field exercises to avoid early problems, (5) establishment and fostering of good relationships and lines of communication with stakeholders and the mass media, (6) addressing liability and workers' compensation concerns prior to initiation of the SPVP, and (7) attention to vaccination clinic logistics.
