The effects of drug education courses on attitudinal change in adult participants.

Five hundred eighty-nine adult participants in 10-day drug education courses held at the National Center for Drug Education in Oklahoma were tested before and after each course to assess changes in their attitudes toward drug use and abuse resulting from the course. Twenty-eight opinion statements were found to significantly distinguish the opinions of different occupational groups both before and after the course. Most participants changed their learning priorities for drug education as a result of the course. Participants' personal history of drug use correlated with changes in their learning priorities for drug education.

Antimicrobial susceptibility of Escherichia coli isolated at a children's hospital.

97 strains of Escherichia coli (49 from urine and 48 from non-urine sources) were isolated from patients at Children's Memorial Hospital, Oklahoma City, and studied for antimicrobial susceptibility. The proportion of highly resistant strains (growth at a concentration of 50 microgram/ml or more) was 27% with ampicillin, 25% with tetracycline, 23% with cephalothin, 6% with kanamycin and neomycin, 4% with chloramphenicol, and zero with colistin, gentamicin, and tobramycin. 23 strains (24%) were found resistant to two or more antibiotics simultaneously. The incidence of strains resistant to ampicillin, cephalothin, kanamycin, neomycin, and tetracycline was higher among urine isolates than among non-urine isolates.

Nurses' assessment of patients' spirituality: continuing education implications.

This article reports the results of a study to determine the extent to which nurses assessed patients' spiritual needs, indicators of spirituality used in the assessments, data collection methods used, and nurses' demographic information related to assessment and methods of data collection. Boutell's Inventory for Identifying Nurses' Assessment of Patients' Spiritual Needs was developed. Test-retest indicated an acceptable level of reliability. The Inventory was sent to a random sample of 817 nurses eligible to practice nursing in Oklahoma, yielding 238 (29%) usable questionnaires. Criteria for inclusion in the study were that the nurses needed to be employed and giving direct care to patients 18 years of age or older. Findings indicate that the majority of nurses assessed their patients' spiritual needs from a moderate to considerable extent. They most frequently assessed for fears, sources of strength, and feelings of hope. Least frequently assessed were integration, giving love to God, meaning in suffering, and transcendence. Moreover, nurses ages 50 to 59 and psychiatric nurses were more likely than other nurses to assess the spiritual realm. Availability of time and patient acuity were major factors that influenced assessment. Data were most frequently obtained through observation of patients and discussions with patients rather than from secondary sources, such as clergy or patient records. Also, the nurses' basic educational preparation was not found to influence assessment. Suggestions for continuing education and programs are made.

Arbovirus surveillance in six states during 1972.

A virus surveillance project was established and maintained during 1972 along 10 major river drainages in six states. Mosquitoes, biting flies, and blood specimens from sentinel equines were collected during 83 field trip visits to 141 arthropod collecting sites and 22 sentinel locations from April into December 1972. There were 173,074 mosquitoes tested and 303 arboviruses isolated from 11 of 41 species. From 13,388 biting flies tested, 8 arbovirus isolations were obtained in 1 of 5 species. There was no isolation of Venezuelan equine encephalitis (VEE) virus. Western equine encephalitis (WEE) virus isolates were the most numerous and were followed by Turlock, St. Louis encephalitis, Hart Park, California encephalitis, and Bunyamwera (BUN) group viruses. The first isolation of WEE from the mosquito Cullex (Mel). erraticus is reported, as is the extension of the ranges for Buttonwillow virus from California to New Mexico and Texas. Also a single isolation of the BUN group from Culicoides variipennis extends the range of this virus-vector relationship from California to Texas. New distribution records for mosquito species previously unreported for Arizona, Louisana, New Mexico, and Oklahoma are reported. The sentinel burros detected WEE serologic conversions at two sites in New Mexico and at one in Texas. The surveillance project provided state and federal officials with current information on the status of arbovirus activity, including the absence of VEE activity during 1972, and it demonstrated the existence of the potential for WEE epizootics and epidemics throughout a wide geographic area of the Western United States.

Susceptibility of Amblyomma americanum to natural and experimental infections with Theileria cervi.

One hundred fifty Amblyomma americanum were examined between March and September 1986 from Cookson Hills Wildlife Refuge in eastern Oklahoma (USA). Of these ticks, 11% (17 of 150) were infected with Theileria cervi. Field-collected nymphal ticks had an 8% (3 of 37) prevalence of infection averaging 1.0 infected acini/nymph. Female ticks had a 16% prevalence of infection averaging 1.6 infected acini/female; T. cervi was not observed in salivary glands of field-collected male ticks. When laboratory reared A. americanum nymphs were allowed to feed on experimental white-tailed deer (Odocoileus virginianus) with varying T. cervi parasitemias (less than 1, 2, 6 and greater than 20%), only ticks which fed on deer with parasitemias greater than 1% became infected. Although prevalence and intensity of infection varied in the infected ticks, there was no significant difference in prevalence of infection between males and females. However, females did acquire significantly greater intensities than males. The data from these studies confirm that T. cervi overwinters in A. americanum and suggests that the prevalence, intensity and abundance of infection of T. cervi in ticks is influenced by the parasitemia of the deer host. Furthermore, fawns may play a more important role in the epidemiology of T. cervi transmission than do adult deer because of the coordination between tick activity patterns and deer fawning.

Influence of habitat modification on the intestinal helminth community ecology of cottontail rabbit populations.

The influence of five brush management treatments using the herbicides tebuthiuron and triclopyr, with or without prescribed burning, on the intestinal helminth community of cottontail rabbits (Sylvilagus floridanus) was studied in 1987 on the Cross Timbers Experimental Range in Payne County, Oklahoma (USA). Six helminth species were found (Dermatoxys veligera, Trichostrongylus calcaratus, Passalurus nonanulatus, Wellcomia longejector, Taenia pisiformis cystercercus, and Mosgovoyia pectinata americana) in 102 rabbits (88 adult and 14 juveniles) collected over two seasons (winter and summer). Prevalence of M. pectinata americana in cottontail rabbits was significantly greater in untreated control pastures than herbicide treated pastures in winter, while prevalence of T. pisiformis was significantly greater in burned than unburned pastures. Abundances of helminth species in the intestinal tract of cottontail rabbits were unaffected by brush treatments. Mosgovoyia pectinata americana abundance demonstrated a highly significant increase from winter to summer; conversely, abundance of all oxyurid pinworms combined (D. veligera, P. nonanulatus, W. longejector) was significantly higher in winter than summer. Helminth community dynamics were significantly influenced by season, but were unaffected by brush treatments. Habitat modification could have influenced cestode transmission by altering the ecology of invertebrate and vertebrate hosts.

Gastropod availability and habitat utilization by wapiti and white-tailed deer sympatric on range enzootic for meningeal worm.

Gastropod occurrence and the utilization of habitat by sympatric populations of wapiti (Cervus elephus) and white-tailed deer (Odocoileus virginianus) on range enzootic for meningeal worm (Parelaphostrongylus tenuis) were studied on Cookson Hills Wildlife Management Area (WMA) in eastern Oklahoma. Visual observations and fecal pellet group transect data indicated that wapiti spent the majority of their time in open fields and meadows where we recovered the least numbers of gastropods. Although deer were frequently observed in open areas, visual sightings and transect data indicated that they spent more time in forested areas where we recovered the most gastropods. Gastropods harbored low numbers of P. tenuis larvae (0.00 to 0.06 larvae/gastropod) in all habitat types with the greatest recovery from red oak white oak-hickory forests (0.34 larvae/gastropod). Our results indicate that the reason a viable wapiti herd exists on Cookson Hills WMA in a P. tenuis enzootic area is at least partially because of the habitat preference by wapiti and the reduced availability of infected gastropods in the selected areas prefered by the wapiti. We were not able to detect any free-ranging wapiti that were shedding P. tenuis larvae nor were we able to detect past or sub-clinical infections with P. tenuis in wapiti.

Control of Psoroptes cuniculi in captive white-tailed deer with ivermectin-treated corn.

Psoroptes cuniculi, the ear mite of domestic rabbits, was collected from captive white-tailed deer (Odocoileus virginianus). This is the first report of rabbit ear mite infestations in white-tailed deer in Oklahoma or Texas (USA). In addition to moderate infestations in their ears, two 4-yr-old bucks, two 3-yr-old does, and seven 4-yr-old does showed patchy areas of alopecia along the sides and brisket. Both bucks also had patchy areas of alopecia around the base of antlers. Ear mites were eradicated from all deer except from one doe by providing ivermectin-treated corn to the deer at a rate of 1,000 g (equivalent to 200 mcg/kg of ivermectin)/day/deer for several days. The ear mite infestation in the one doe was eradicated by intramuscularly injection with ivermectin at 400 mcg/kg. After treatment with the ivermectin and eradication of the mites, the alopecia improved and eventually was eliminated. The ivermectin-treated corn also controlled all internal nematode parasites in the deer.

Influence of habitat modification on the community of gastrointestinal helminths of cotton rats.

Dynamics of communities of gastrointestinal helminths of cotton rats (Sigmodon hispidus) were monitored in response to five experimental brush management treatments using herbicide applications with and without prescribed burning on the Cross Timbers Experimental Range in Payne County, Oklahoma (USA). A total of 113 adult cotton rats (68 male and 45 female) was collected from experimental pastures in winter and summer 1986 resulting in the recovery of five species of helminths: Longistriata adunca, Syphacia sigmodontis, Strongyloides sp., Protospirura muris, and Raillietina sp. Prevalences of Raillietina sp. and S. sigmodontis were greater on control than herbicide-treated pastures. Prevalence and abundance of Raillietina sp. and prevalence of S. sigmodontis were significantly lower on annually burned, herbicide-treated pastures compared to unburned herbicide-treated pastures. Triclopyr-treated pastures had greater abundances of L. adunca and lower abundances of Raillietina sp. than those treated with tebuthiuron. Abundances of L. adunca also decreased from winter to summer on annually burned, herbicide-treated pastures while increasing on other pastures. Distribution of all helminths was overdispersed, but distribution of L. adunca showed a significant brush treatment by season interaction as a result of greater overdispersion in summer than winter for cotton rats inhabiting brush-treated pastures. Our results indicate that man-induced habitat modifications can alter host-parasite relationships in the community.

Environmental, age, and sex effects on cotton rat (Sigmodon hispidus) hematology.

We determined the effects of sex, age, and environment (inbred, captive-wild, and wild animals) on selected blood parameters of the cotton rat (Sigmodon hispidus) in central Oklahoma (USA) from 1990 to 1994. Male and female cotton rats had similar blood profiles. Age-related differences were confined to differential white blood cell counts where adults possessed greater numbers of neutrophils and lower numbers of lymphocytes compared to juveniles. Environment had a strong influence on many hematological parameters. Hematocrit, hemoglobin concentration, RBC count, and eosinophil number were generally greater for wild stocks compared to inbred animals, and differences were more pronounced for adults than juveniles.

Sensitivity of condition indices to changing density in a white-tailed deer population.

The ways in which comprehensive condition profiles, incorporating morphometric, histologic, physiologic, and diet quality indices, responded to changes in density of a white-tailed deer (Odocoileus virginianus) population were examined. Changes in these condition indices were monitored in a northeastern Oklahoma deer herd as density declined from peaks of 80 and 72 deer/km2 in 1989 and 1990 (high-density) to lows of 39 and 41 deer/km2 in 1991 and 1992 (reduced-density), respectively. Compared to a reference population (6 deer/km2), deer sampled during high-density exhibited classic signs of nutritional stress such as low body and visceral organ masses (except elevated adrenal gland mass), low fecal nitrogen levels, reduced concentrations of serum albumin, elevated serum creatinine concentrations, and a high prevalence of parasitic infections. Although density declined by one half over the 4-yr study, gross indices of condition (in particular body mass and size) remained largely unchanged. However, selected organ masses, serum albumin and non-protein nitrogen constituents, and fecal nitrogen indices reflected improvements in nutritional status with reductions in density. Many commonly used indices of deer condition (fat reserves, hematocrit, total serum protein, and blood urea nitrogen) were not responsive to fluctuations in density.

Epizootic podoknemidokoptiasis in American robins.

Epizootics of scaly leg disease caused by infection with the submacroscopic mite Knemidokoptes jamaicensis (Acari: Knemidokoptidae) in migratory American robins (Turdus migratorius) from a residential area of Tulsa (Oklahoma, USA) are documented during the winters (December through February) of 1993-94 and 1994-95. Estimates of 60 to > 80% of the birds in several different flights arriving in the area had lesions consistent with knemidokoptic mange. Epizootic occurrence of K. jamaicensis also is confirmed incidentally in American robins from Georgia (USA) in 1995 and 1998 and in Florida (USA) in 1991. These are the first confirmed epizootics of scaly leg attributed to infections with mites specifically identified as K. jamaicensis in North America. Severity of observed lesions in American robins ranged from scaly hyperkeratosis of the feet and legs to extensive proliferative lesions with loss of digits or the entire foot in some birds. Histologically, there was severe diffuse hyperkeratosis of the epidermis which contained numerous mites and multifocal aggregates of degranulating to degenerating eosinophilic heterophils; there was mild to severe superficial dermatitis with aggregates of eosinophilic heterophils and some mononuclear cells. Based on limited data from affected captive birds in Florida, we questioned the efficacy of ivermectin as an effective acaricide for knemidokoptiasis and propose that conditions associated with captivity may exacerbate transmission of this mite among caged birds. While knemidokoptic mange apparently can result in substantial host morbidity and possibly mortality, the ultimate impact of these epizootics on American robin populations presently is unknown.

Fluorosis risks to resident hispid cotton rats on land-treatment facilities for petrochemical wastes.

Land-treatment of petroleum wastes is a widely used industrial practice, yet there has been no comprehensive evaluation of the long-term risks to human or terrestrial ecosystems from such practices. We evaluated cotton rat (Sigmodon hispidus) populations on three sites in Oklahoma (USA) that historically used land-treatment for disposal of various petroleum wastes (July 1995-March 1997). Average concentrations of fluoride in soil from these sites ranged from 878 to 4317 mg/kg. A census of resident cotton rats on land-treatment sites revealed a high incidence (40% overall) of dental lesions compared to reference populations (<1% dental lesions). During winter there was a 34% to 65% increase compared to summer in frequency of dental lesions in cotton rats on two of the three land-treatment sites. Incidence of dental lesions on two land-treatment sites was greater (9-16%) in female cotton rats compared to males. Cotton rats from land-treatment sites had higher concentrations of fluoride in bone and greater severity of dental lesions compared to reference animals. Dental lesions were considered to be most consistent with dental fluorosis because of elevated fluoride in bone. Neither concentration of fluoride in soil nor level of fluoride in bone was a good predictor of severity of dental lesions in cotton rats on land-treatment sites.

Zinc toxicosis in a free-flying trumpeter swan (Cygnus buccinator).

A trumpeter swan (Cygnus buccinator) was observed near a mill pond in Picher, Oklahoma, USA. It became weakened and emaciated after about 1 mo, was captured with little resistance, and taken into captivity for medical care. Serum chemistry results were consistent with hepatic, renal, and muscular damage. Serum zinc concentration was elevated at 11.2 parts per million (ppm). The swan was treated for suspected heavy-metal poisoning, but died overnight. Gross postmortem findings were emaciation and pectoral muscle atrophy. Histopathologic lesions in the pancreas included mild diffuse disruption of acinar architecture, severe diffuse depletion or absence of zymogen granules, occasional apoptotic bodies in acinar epithelial cells, and mild interstitial and capsular fibrosis. Zinc concentration in pancreas was 3,200 ppm wet weight, and was similar to that reported in the pancreases of waterfowl known to be killed by zinc toxicity. Zinc concentrations in liver (154 ppm) and kidneys (145 ppm) also were elevated. Acute tubular necrosis of the collecting tubules of the kidneys was also possibly due to zinc toxicity. To the authors' knowledge, this is the first confirmed case of zinc poisoning in a trumpeter swan associated with mining wastes.

Training psychiatric residents for Part II of the American Board of Psychiatry and Neurology Examination.

Of the physicians who took the American Board of Psychiatry and Neurology (ABPN) Examination, Part II, in 1995, 41% failed. The Accreditation Council for Graduate Medical Education (ACGME) requires that residency psychiatry programs conduct an organized evaluation of residents' clinical skills at least twice during the 4 years of training. At the University of Oklahoma Health Science Center-Tulsa, the residents attend formal didactic instruction on conducting a psychiatric interview. Having gained this didactic foundation, they then participate in actual patient interviews. First- and 3rd-year residents are mock examiners, paired with an experienced board-certified psychiatrist. Second- and 4th-year residents examine an actual patient. A survey evaluating this curriculum was rated as very good to excellent by the participants.

On the right path. Collaborative case management makes nurses partners in the care-planning process.

The quality improvement movement in healthcare has given nurses a greater role in developing and implementing collaborative case management processes. In the case management model, nurses no longer simply take orders but actively participate in designing a plan of care. At Mercy Health Center, Oklahoma City, nurses play a leading role in the development of "clinical pathways," plans of care for a single diagnosis as directed by a specific physician or group of physicians. The pathways promote multidisciplinary, interdepartmental cooperation in patient care. Since August 1992, Mercy has developed clinical pathways for five inpatient and outpatient procedures, and more are being considered. Once a plan has been created, its key points are rewritten in lay terms and printed in a brochure for the patient. During the treatment, nurses and other healthcare professionals document when specific steps in the plan have been completed. In follow-up evaluations Mercy's steering committee for the collaborative care process has found that the clinical pathways have maximized quality, improved efficiency, increased patient satisfaction, and enhanced collaborative team practice.

A delicate balancing act.

This week, Modern Healthcare begins a two-part series examining the growing number of sales of not-for-profit hospitals to for-profit chains and the consequences of those sales for the communities involved. The stories in this installment explore whether a community benefits more from having an investor-owned hospital that pays taxes or a tax-exempt hospital that provides more charity care. They also review how this issue played out in Oklahoma City 10 years after a sale. Next week: a look at whether charitable foundations created with the proceeds of sales of not-for-profits deliver on their promises. Also, an analysis of Columbia/HCA Healthcare Corp.'s strategy of acquiring not-for-profits through partnership arrangements.

Are we getting the help we need.

The Oklahoma City bombing was a made-for-TV catastrophe. The images thrust on the EMS community after the devastation of the Alfred P. Murrah Federal Building last April are imprinted on our minds with awful clarity. And to see images of other disasters often causes memories of other awful scenes to arise unbidden: Sioux City's airline disaster, the New York City World Trade Center bombing, hurricanes, earthquakes and other devastation. Each takes its toll on emergency care providers.
