Epidemiology of salmonellosis in Arkansas.

Human salmonellosis continues to be a major public health issue. Our epidemiologic review of cases from 1989 to 1992 was done to define the current reported rate of infection due to Salmonella species for the state of Arkansas, which might be expected to have higher rates of infection because it is a leading producer of poultry. Results showed that the reported case rate in Arkansas (18.0/100,000) did not differ from that of the United States at large (18.6/100,000). Age-specific rates, however, showed that children less than 1 year of age in Arkansas were infected at a higher rate than those in the remainder of the nation. Salmonella newport and S typhimurium were the most commonly isolated serotypes. Individuals living in a county with poultry processing plants and hatcheries were not more likely to have salmonellosis, and individuals residing in Arkansas do not appear to be at increased risk of salmonellosis because of the poultry industry.

Seasonal changes in pyrethroid resistance in tarnished plant bug (Heteroptera: Miridae) populations during a three-year period in the delta area of Arkansas, Louisiana, and Mississippi.

Tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois), were collected from weeds at 71 locations in the delta of Arkansas, Louisiana, and Mississippi and tested with a discriminating dose bioassay for pyrethroid resistance in the spring (April-May) and again at the same locations in the fall (September-October) in 1995-1997. Percentage of mortality in the discriminating dose bioassay declined significantly (pyrethroid-resistance increased) from spring to fall by an average 18.7, 21.3, and 21.7% in Arkansas, Louisiana, and Mississippi, respectively. Pyrethroid resistance declined significantly by 26.3% from the fall of 1995 to the spring of 1996 in Mississippi, but did not significantly decline in Arkansas (4.1%) and Louisiana (13.2%). Significant decreases in resistance occurred in all 3 states from the fall of 1996 to the spring of 1997 (17.1, 38.3, and 29.8% in Arkansas, Louisiana, and Mississippi, respectively). Plant bugs from 2 locations (Indianola, MS, and Wainwright, LA) had multiple insecticide resistance to a carbamate, 2 pyrethroid, and 4 organophosphorus insecticides. However, resistance to the organophosphate acephate in plant bugs from both locations was not significant. Possible causes for the significant increases and declines in resistance from season to season are discussed.

Pharmaceuticals and other organic chemicals in selected north-central and northwestern Arkansas streams.

Recently, our attention has focused on the low level detection of many antibiotics, pharmaceuticals, and other organic chemicals in water resources. The limited studies available suggest that urban or rural streams receiving wastewater effluent are more susceptible to contamination. The purpose of this study was to evaluate the occurrence of antibiotics, pharmaceuticals, and other organic chemicals at 18 sites on seven selected streams in Arkansas, USA, during March, April, and August 2004. Water samples were collected upstream and downstream from the influence of effluent discharges in northwestern Arkansas and at one site on a relatively undeveloped stream in north-central Arkansas. At least one antibiotic, pharmaceutical, or other organic chemical was detected at all sites, except at Spavinaw Creek near Mayesville, Arkansas. The greatest number of detections was observed at Mud Creek downstream from an effluent discharge, including 31 pharmaceuticals and other organic chemicals. The detection of these chemicals occurred in higher frequency at sites downstream from effluent discharges compared to those sites upstream from effluent discharges; total chemical concentration was also greater downstream. Wastewater effluent discharge increased the concentrations of detergent metabolites, fire retardants, fragrances and flavors, and steroids in these streams. Antibiotics and associated degradation products were only found at two streams downstream from effluent discharges. Overall, 42 of the 108 chemicals targeted in this study were found in water samples from at least one site, and the most frequently detected organic chemicals included caffeine, phenol, para-cresol, and acetyl hexamethyl tetrahydro naphthalene (AHTN).

Arkansas and the motorcyle helmet law.

Motorcycle helmet laws have a long and colorful history dating back to the original work of Britain's Dr. Hugh Cairns during World War II. In Arkansas, the state's mandatory motorcycle helmet law was repealed in 1997 and replaced by a law requiring only those under the age of 21 to wear helmets. Recent work by researchers at the University of Arkansas for Medical Sciences has highlighted the impact of the helmet law repeal and demonstrated an increase in nonhelmeted motorcycle crash admissions, head injury severity, ICU length of stay and financial loss at this institution. In February of 2003, House Bill 1024 was submitted to the Arkansas House Committee on Public Transportation to reinstate the mandatory motorcycle helmet law for all motorcycle riders but was killed in committee. This article is a review of motorcycle helmet laws with particular emphasis on the arguments pro and con and the history of these laws in the state of Arkansas.

Comparisons of the genomic RNA of Arkansas DPI embryonic passages 10 and 100, Australian T, and Massachusetts 41 strains of infectious bronchitis virus.

The genomic ribonucleic acid (RNA) of Arkansas DPI at embryonic passages 10 and 100, Australian T, and Massachusetts 41 strains of infectious bronchitis virus (IBV) were compared using two-dimensional, 32PpCp-labeled oligonucleotide fingerprinting. The Arkansas DPI strain embryonic passage 10 was pathogenic for chickens and had one oligonucleotide not present in the attenuated passage 100. The remaining Arkansas DPI oligonucleotides had identical electrophoretic mobility. The fingerprint patterns of the Australian T, Massachusetts 41, and Arkansas DPI IBV genomes were dissimilar, thus indicating they were genetically distinct. The distinctive fingerprint patterns of these virus strains, all identified as IBV by other criteria, indicate considerable genomic variation. Fingerprinting is reliable and sensitive, and should be used in combination with other characterization methods for identifying and differentiating IBV strains.

Barriers to public health management of a pertussis outbreak in Arkansas.

BACKGROUND: During the 2001-2002 respiratory season, Arkansas experienced one of its worst pertussis outbreaks. This crisis occurred shortly after the September 11, 2001, terrorist attacks. OBJECTIVE: To determine whether vulnerabilities in the public health infrastructure existed in the context of emerging infectious diseases or possible bioterrorist attacks. DESIGN: Key personnel involved in the Arkansas pertussis outbreak were interviewed, and health department epidemiologic data were reviewed. SETTING: Observations were made for the statewide private-public management of the epidemic. PARTICIPANTS: Physicians, infectious disease specialists, epidemiologists, field nurses, health department staff, laboratory staff, and administrators. MAIN OUTCOME MEASURES: Diagnosis capability; vaccine, prophylaxis, and treatment programs; and effectiveness of global outbreak management. RESULTS: Diagnosis of pertussis was a major barrier to management of the outbreak. The nonspecific clinical diagnosis, unreliability of testing methods, excessive number of samples, unavailability of reagents, and inadequate transport system, laboratory personnel, and equipment all impeded effective diagnosis. Vaccine shortage was not believed to contribute to the extent of the outbreak. Prophylaxis was problematic because of feared adverse effects of drugs and uncertainty about the efficacy of new drugs, but compliance was found to be good. From a public health perspective, isolation procedures, school absence policies, and health department referrals to private physicians all contributed to confusion. Problems with communications, staffing, and public cooperation were identified. Despite these barriers, the epidemic was well tolerated, with no known mortality and limited morbidity. CONCLUSIONS: Despite many identified barriers to effective public health management, Arkansas tolerated its worst epidemic of pertussis in many years. However, were the state to experience an outbreak of a more pathogenic agent, introduced either naturally or of bioterrorist origin, these vulnerabilities could become critical. Natural outbreaks serve as excellent experiences on which to recognize and correct barriers to public health management.

Arkansas Special Populations Access Network perception versus reality--cancer screening in primary care clinics.

The origin of cancer health disparities and mortality in Arkansas is multifactorial. In response to a cooperative agreement with the National Cancer Institute's Center to Reduce Cancer Health Disparities, the Arkansas Special Populations Access Network (ASPAN) was developed to reduce these disparities. ASPAN's partnership with local primary care physicians of the Arkansas Medical, Dental, and Pharmaceutical Association through the Cancer Education Awareness Program is the focus of this article. A quasi-experimental intervention, the Community Cancer Education Awareness Program, was employed that included 1) physician education to increase awareness of risk factors and cancer screening; and 2) patient education to increase screening, and 3) patient-generated screening questionnaires to prompt discussion of cancer risk and screening recommendations between patients and physicians. Two urban and 2 rural clinics were targeted during a 12-month period with interval intervention assessments. Baseline review of records (n = 200) from patients >/=40 were utilized to assess the rate of breast, prostate, and colorectal screenings among clinics. For the patient education intervention, patients (n = 120) were interviewed via a 34-item assessment. Physician awareness of cancer risk factors and screening recommendations significantly increased. Statistically significant increases were seen for prostate (P = .028), breast (P = .036), and colorectal (P < .001) cancer screening across all 4 clinics. Patients' increased likelihood of cancer screenings was associated with knowledge about consumption of animal fat (P < .001), dietary fiber (P < .013), and mammograms (P < .001). Utilizing the physician as the central change agent, the ASPAN provider network successfully enhanced cancer screening awareness of minority physicians and their patients. Cancer 2006.

Rock v. Arkansas: a critique.

Rock v. Arkansas is the first United States Supreme Court decision that addresses the conflict between a criminal defendant's right to testify in his or her own behalf and a state's right to impose a restrictive rule of evidence barring hypnotically refreshed testimony. The present critique describes the operative facts in Rock v. Arkansas and the majority and minority decisions. It also highlights some of the psychological and legal issues involved and speculates on what Rock v. Arkansas may portend for the broader issue of the admissibility of hypnotically refreshed testimony in general.

The epidemiology of Rocky Mountain spotted fever in Arkansas, Oklahoma, and Texas, 1981 through 1985.

From 1981 through 1985, a total of 851 laboratory-confirmed cases of Rocky Mountain spotted fever were reported in Arkansas, Oklahoma, and Texas. Annual incidence rates in each state increased from 1981 through 1983, ranging from a 17% increase in Arkansas to a 137% increase in Texas. In the period 1984 through 1985, the annual incidence rates in each state decreased over 50%. A total of 519 cases were males. A majority of cases (51%) were 19 years of age or younger. April through August were the months of onset of symptoms for 83% of the cases. Differences in distribution of month of onset of symptoms were noted when comparing age groups and state of residence of the cases. The case-fatality ratio was 4.7%. Case-fatality ratios were higher in blacks and in older age groups. An endemic focus of Rocky Mountain spotted fever exists in Arkansas, Oklahoma, and Texas. The annual incidence trend for spotted fever in these three states is dissimilar to the trends in other states.

A profile of reported skunk rabies in Arkansas: 1977-1979.

Skunk rabies in Arkansas increased from 90 laboratory confirmed cases in 1977 to 140 in 1978 and 297 in 1979. In 1979, the Arkansas Department of Health declared a skunk rabies epizootic in Arkansas. Skunk rabies accounted for 90% of the total rabies cases in 1978 and 1979. March, April and May had the highest incidence in each year. SYMVU computer analysis illustrated the distribution and spread of rabies. In general, rabies was confined to the upland areas of the state. Regression analysis of 16 density-independent variables revealed no correlation with the distribution of rabies, indicating the primary determinants to be biotic.

A survey of infectious diseases in wild turkeys (Meleagridis gallopavo silvestris) from Arkansas.

Wild turkeys (Meleagridis gallopavo silvestris) trapped as part of a relocation program by the Arkansas Game and Fish Commission were tested for selected infectious diseases and parasites. The 45 birds were trapped at four locations in Pope, Scott, and Montgomery counties (Arkansas, USA). Forty-four blood samples for serology, 27 blood smears and 12 fecal samples were collected. Of the serum samples tested, 20 of 44 (45%) were positive for Pasteurella multocida by enzyme-linked immunosorbent assay (ELISA), 42 of 44 (95%) were positive for Bordetella avium by ELISA, and 15 of 44 (34%) were positive for Newcastle disease virus antibody by the hemagglutination inhibition test. All serum samples were negative for Mycoplasma gallisepticum, Mycoplasma synoviae, avian paramyxovirus 3, avian influenza, hemorrhagic enteritis, Marek's disease, avian encephalomyelitis, laryngotracheitis, Salmonella pullorum and Salmonella gallinarum. Haemoproteus meleagridis was found in eight of 27 (30%) and Leucocytozoon smithi in nine of 27 (33%) blood smears; all smears were negative for Plasmodium hermani. Enteric parasites included Ascaridia dissimilis, Heterakis gallinarum, Eimeria dispersa and Raillietina spp. This study was an attempt to document the health status and disease exposure of wild turkeys in Arkansas to aid in managing and preventing the spread of disease agents to wild turkeys and other species of birds.

Morbidity and cost of vaccine-preventable varicella in previously healthy children in Arkansas.

Many physicians have not recognized varicella as a serious disease and are not advocating use of varicella vaccine. This retrospective study describes the morbidity and costs incurred by previously healthy children hospitalized at Arkansas Children's Hospital due to complications of varicella during a time period when an effective vaccine was approved for use. Fifty-five previously healthy children from 19 countries in Arkansas were hospitalized secondary to complications of varicella in the three years following release of varicella vaccine. Total numbers of hospital days for these patients were 192 with a cost totaling $252,084. Increased efforts are needed to vaccinate the children of Arkansas against varicella.

The reality of mammography utilization in the state of Arkansas.

The Arkansas Mammography Data Collection Project, funded by the Arkansas Department of Health, aimed to determine the mammography screening patterns throughout the state of Arkansas. Data were obtained from 92 mammoraphy centers out of 112 centers (82%). A total of 157,976 mammography data sets were obtained for 148,586 women. Mammography rate was 22.7% for women 40 years and older and 24.1% for women 50 years and older. Mammography rates per county varied from 0.3% to 42.6%. The overall low rate of mammography utilization reflects the need to intensify public health interventions and continuous evaluations of these interventions.

St. Louis encephalitis in Arkansas.

The first outbreak of St. Louis encephalitis (SLE) in Arkansas occurred in Pine Bluff (Jefferson County) during July-August 1991. Cases of SLE were identified mainly through reporting by physicians in Jefferson and surrounding counties. In addition, testing of stored cerebrospinal fluid specimens, a hospital chart review, and a serosurvey were performed in Pine Bluff. Twenty-eight Arkansas residents, five of whom died, had cases of SLE. Half the case patients were over age 60, and nearly half had hypertension. The serosurvey confirmed that infection with the SLE virus was not new to Pine Bluff, and that most infections in 1991 were asymptomatic. Arkansas physicians may see more cases of SLE in 1992. SLE epidemiology, clinical presentation, diagnosis, and preventive measures are reviewed.

Update: investigation of rabies infections in organ donor and transplant recipients--Alabama, Arkansas, Oklahoma, and Texas, 2004.

On July 1, 2004, CDC reported laboratory confirmation of rabies as the cause of encephalitis in an organ donor and three organ recipients at Baylor University Medical Center (BUMC) in Dallas, Texas. Hospital and public health officials in Alabama, Arkansas, Oklahoma, and Texas initiated public health investigations to identify donor and recipient contacts, assess exposure risks, and provide rabies postexposure prophylaxis (PEP). As of July 9, PEP had been initiated in approximately 174 (19%) of 916 persons who had been assessed for exposures to the organ recipients or the donor. As a result of its public health investigation, the Arkansas Department of Health determined that the donor had reported being bitten by a bat (Frank Wilson, M.D., Arkansas Department of Health, personal communication, 2004).

Barriers to diabetes self-management education programs in underserved rural Arkansas: implications for program evaluation.

BACKGROUND: Diabetes prevalence has reached epidemic proportions. Diabetes self-management education (DSME) has been shown to improve preventive care practices and clinical outcomes. In this study, we discuss the barriers faced during the implementation of DSME programs in medically underserved rural areas of Arkansas. CONTEXT: Arkansas is a rural state, with most southeastern counties experiencing a shortage of health care professionals. The Arkansas Diabetes Prevention and Control Program and its partners established 12 DSME programs in underserved counties with a high prevalence of diabetes. METHODS: DSME programs were delivered by a registered nurse and a dietitian who provided 10 to 13 hours of education to each program participant. Baseline, 6-month, and year-end data were collected on preventive care practices, such as daily blood glucose monitoring, foot examination, systolic and diastolic blood pressure, and glycosylated hemoglobin level, among the participants in newly established DSME programs. CONSEQUENCES: Of the 12 DSME programs established, 11 received American Diabetes Association recognition. The number of participants in the DSME programs increased 138% in 1 year, from 308 in February 2003 to 734 in March 2004. Preventive care practices improved: daily blood glucose monitoring increased from 56% to 67% of participants, and daily foot examinations increased from 63% to 84% of participants. Glycosylated hemoglobin decreased by an average of 0.5 units per participant who completed the program. However, many anticipated and a few unanticipated barriers during the implementation of the program could not be overcome because of the lack of an evaluation plan. INTERPRETATION: Although results point to potential benefits of preventive care practices among DSME participants, interpretation of findings was limited by sample size. Sample size limitations are traced to barriers to assessing program outcome. Program evaluation should be integrated into the planning phase to ensure adequate measures of program effectiveness.

Overweight among students in grades K-12--Arkansas, 2003-04 and 2004-05 school years.

Prevalence of overweight among children nearly doubled from 1976-1980 to 1999-2002 in the United States. During 1999-2002, approximately 65% of adults aged > or =20 years were overweight or obese, according to the National Health and Nutrition Examination Survey (NHANES). Among persons aged 6-19 years during the same period, 31% were overweight or at risk for overweight. In 2003, the Youth Risk Behavior Surveillance (YRBS) survey indicated that 27% of high school students were overweight or at risk for overweight. Among adolescents with a body mass index (BMI) at or above the 95th percentile, approximately 50% will become obese adults, and 70% will become obese or overweight adults. Although NHANES and YRBS provide population-based, cross-sectional state and national samples, no studies reflect a national or statewide longitudinal cohort assessment of childhood and adolescent obesity. The American Academy of Pediatrics (AAP) and the Institute of Medicine recommend annual assessments of BMI as a strategy for preventing and combating childhood obesity. In 2003, Arkansas implemented a multifaceted statewide initiative to reduce and prevent overweight among children. A key aspect of this initiative (Act 1220) is the mandated annual statewide BMI assessments of all Arkansas public school students with confidential reporting of results to parents. This report describes the results of this large-scale population screening, which indicated that, during the 2003--04 and 2004--05 school years, 38% of Arkansas students were overweight or at risk for overweight. This finding suggests a more severe problem than that reported for other states. Because rates of childhood and adolescent obesity in certain areas might be higher than anticipated, health policy decisions that address health outcomes and cost of care should be based on state-specific, population-based data.
