Long-term experience with Swan Neck Missouri catheters.

The Swan Neck Missouri catheters are designed to reduce major complications including 1) exit/tunnel infections, by a downward directed exit hole; 2) pericatheter leaks, by placement of the deep cuff in the rectus muscle; 3) catheter tip migration, by caudal direction of the intraperitoneal segment; and 4) outer cuff extrusion, by a permanent bend between the 5 cm or 3 cm spaced cuffs in SN-M2 and SN-M3 catheters, respectively. Between April 1986 and April 1990, 103 swan neck catheters were implanted. Comparison of prospective data from 103 swan neck catheters and retrospective data from 148 standard (Tenckhoff and Toronto Western Hospital) catheters implanted between January 1982 and June 1985 showed reduced complication rates with swan neck catheters. An overall survival of 64% at 36 months for swan neck catheters is significantly better than that of 29% for standard catheters.

Increased scope of practice: a survey of Missouri doctors of optometry.

This study attempts to assess the effects on the Missouri optometric community resultant from the recent expansion in the scope of practice to include the management of ocular disease with pharmaceutical agents. A majority of those responding reported they felt comfortable in providing such services. They also reported an increase in income and patient retention. Improved relations with ophthalmologists and a greater willingness to comanage patients were perceived by some as other benefits. Over half of the respondents have received referrals from primary care physicians for therapeutic services.

Practice profile of University of Missouri-St. Louis optometry graduates.

The results of a survey of the University of Missouri-St. Louis School of Optometry graduates are presented. The practice mode selected and relocation throughout the country is examined for the school's first four graduating classes. Approximately two-thirds of the graduates remained in the state with more than half in proximity of the school. Of these, one-third to one-half maintain "commercial" affiliations.

Vision screening of school age children in Missouri.

In this report, vision screenings conducted by schools in the state of Missouri are reviewed. Data were generated by the 127 participating schools in 38 school districts that responded to four research questions. In general, many inadequacies exist in schools regarding vision screening. Recommendations include greater participation in the public school arena by vision specialists and the development of consistent criteria for vision screening in school districts.

A comparison of academic performance of female and male optometry students at the University of Missouri-St. Louis.

The number of women entering optometry has risen steadily over the last 2 decades. The present study compares the academic performance of male and female optometry students in the 1984 through 1986 graduating classes at the University of Missouri-St. Louis School of Optometry. The female students had higher grade point averages upon entering optometry school than their male colleagues although they performed less well than the males on the Optometry College Admissions Test (OCAT) examination. An analysis of optometry grade point averages, class rank and honors received at graduation demonstrated that the women performed at least as well academically as their male counterparts.

2,3,7,8-Tetrachlorodibenzo-p-dioxin levels in adipose tissue of exposed and control persons in Missouri. An interim report.

The compound 2,3,7,8-tetrachlorodibenzo-p-dioxin, commonly known as dioxin, was measured in the adipose tissue of 39 persons with a history of residential, recreational, or occupational exposure in Missouri and in 57 persons in a control group. All participants had detectable levels of 2,3,7,8-tetrachlorodibenzo-p-dioxin in their adipose tissue, but the exposed group had significantly higher levels. Levels of six of the exposed persons were more than five times greater than the level of the highest control. Measuring 2,3,7,8-tetrachlorodibenzo-p-dioxin in adipose tissue provides a much improved index of exposure, an important advance for research studies evaluating the possible health effects of this compound.

Evaluation of the Missouri WIC program: prenatal components.

A study was performed to evaluate the prenatal components of the Missouri Special Supplemental Food Program for Women, Infants and Children (WIC) Program. The study used WIC prenatal participants delivering in 1980 and their offspring's birth/fetal death certificates. A 93% match rate was acquired with a final study population of 6,732. Three basic methods of overall analysis were used to acquire a comparison group: covariate analysis, standardization, and pair matching. A higher mean birth weight was noted for the WIC total and WIC non-white group when the method of analysis was covariate or standardization; the latter was statistically significant. In either instance, the amount of increase was small. A reduced low-birth-weight rate was noted for the WIC total and the WIC non-white group regardless of the method of analysis used; the differences were statistically significant for the standardization method. Duration in WIC had a positive influence on both mean birth weight and low birth weight, regardless of race. High-risk groups used for program participation also were analyzed. Overall, this study showed that WIC prenatal nutritional supplementation has a positive, though not conclusive, impact on reducing low birth weight and raising mean birth weight.

Field evaluation of test-and-removal and vaccination as control measures for pseudorabies in Missouri swine.

Eighteen Missouri swine herds were serologically monitored to determine the efficiency of two methods for the control of pseudorabies. A serum neutralization test-and-removal procedure was effective in ten of ten herds using this method. Vaccination procedures were less reliable. Virus still circulated in five of eight vaccinated herds and a thorough epidemiological evaluation of herd status was impossible. Titers caused by vaccination could not be distinguished from those by natural infection. Vaccination also was carried out in three seronegative herds. Antipseudorabies virus titers in these herds ranged from negative to 1:16 two to three months postvaccination. A majority of the sows in these herds responded with low 1:2 or 1:4 titers following vaccination. A direct comparison of "test and removal" farms and farms that used vaccination was not possible because of the differences between the two groups of farms.

Craniofacial anomalies in the Upper Missouri River over a millennium: archeological and clinical evidence.

Congenital facial clefting occurs more often in Native Americans from the Upper Missouri River Basin (UMRB) than it does in the general population. However, no facial clefts were seen in 3,750 ancient UMRB skeletons. Very few reports concerning defective palate crania are in the literature of paleopathology. Findings regarding craniofacial anomalies in today's native Americans in the UMRB are presented briefly and compared to those in skeletons from this region. There is a marked difference between the frequency of anomalies which occurred in the past and those which are present today. Although the people sampled here were from many cultures and lived during different time periods, encompassing over a millenium, the fundamental denominator was a common geographic location. Reasons for the differences between the past and the present are advanced. It may be possible to estimate the frequency of anomalies which have not been found in archeological specimens but which are present today. By comparing data concerning "occult" congenital anomalies of the past with those of the present, the actual prevalence of past cranio-facial anomalies may be estimated through careful extrapolation.

Dieldrin and heptachlor residues in dead gray bats, Franklin County, Missouri--1976 versus 1977.

Lethal dieldrin concentrations were found in the brains of dead gray bats (Myotis grisescens) collected during 1976 and 1977 beneath a maternity roost in a Missouri cave. In addition, residues of heptachlor epoxide, oxychlordane, cis-chlordane, and trans-nonachlor increased significantly in both brains and carcasses of bats collected during 1977. These increases appear to reflect a switch by local farmers from aldrin, dieldrin's parent compound, to heptachlor for the control of cutworms. They also constitute an additional threat to this colony of this endangered bat species.

A case of Whipple's disease in Missouri.

Whipple's disease is a rare disorder which has fascinated physicians since its description in 1907. The onset is usually indolent, the symptoms are protean and multisystemic, and disease has often been present for years before a diagnosis is made. Although rare, its identification is important since therapy is simple and effective. We report a case of Whipple's disease in a lifelong resident of Missouri and review the important features of the disease.

Visual characteristics of Missouri State Highway Patrol troopers.

BACKGROUND: The Missouri State Highway Patrol (MSHP) had 902 troopers on duty at the time of this study. The purpose of this study was to determine, for the first time, the visual characteristics of this group. METHODS: All 902 troopers were requested to be screened during early 1993 at their local MSHP troop headquarters. Vision screening was done by Department of Motor Vehicle Personnel using Keystone/Mast DVS II Driver Vision Screeners. The results, along with current prescriptions obtained from their eye care practitioners, were mailed to the author. RESULTS: A 94 percent response rate was achieved. The group's mean age was 38.7 years and most (98 percent) were male. Forty-seven percent wear an optical correction either some or all of the time and these were evenly divided between single vision and multifocal corrections. Seventy-four percent of eyes had uncorrected distance acuity of 20/20 increasing to 94 percent of eyes with 20/20 when corrections were worn. CONCLUSIONS: The results of this study will be used as a basis to update MSHP vision standards for acquisition and retention of troopers.

Incidence of nonarteritic and arteritic anterior ischemic optic neuropathy. Population-based study in the state of Missouri and Los Angeles County, California.

This population-based study was undertaken to obtain information on age-, sex-, and race-specific incidence of nonarteritic and arteritic anterior ischemic optic neuropathy for the State of Missouri and for Los Angeles County, California. Among subjects who were 50 or older the estimated mean annual incidence rates per 100,000 population were 2.30 for nonarteritic anterior ischemic optic neuropathy and 0.36 for arteritic anterior ischemic optic neuropathy. White individuals appear to be at significantly higher risk of developing nonarteritic anterior ischemic optic neuropathy than black or Hispanic individuals, suggesting possible genetic predisposition.
