Welcome to the Department of Anesthesiology and Perioperative Medicine at the University of Missouri in Columbia. Columbia is a city of approximately 100,000 population located in the center of the state. It is home to Missouri's flagship university, MU, which includes schools of medicine, nursing, health professions, veterinary medicine, business, law and engineering. Surrounded with beautiful rolling hills nearby the Missouri River, Columbia offers a very high standard of living and some of the finest public schools in the country at relatively low cost, along with the wide range of cultural activities one would expect in a well-respected university setting.

INTRODUCTION: The stimulus for this presentation was an asthma attack suffered on the first dive by a victim of a severe industrial electrical burn. The patient’s response to albuterol metered dose inhaler (MDI) treatment given at depth was felt to have been poor. We thus wondered what the output of these devises (chlorofluorocarbon or CFC) was at therapeutic depth versus normobaria. As the current MDIs were being phased out of use we also wondered what the comparable output characteristics of the replacement MDIs (hydrofluoroalkane or HFA) would be. MATERIALS AND METHODS: The dose and aerosol particle size and number delivered by MDIs were measured in a hyperbaric chamber at pressures ranging from one atmosphere absolute (1 ATA, 0 feet of seawater, fsw, 101 kPa) to three ATA (66 fsw, 304 kPa). Mass delivered was measured by a Sartorius B120 analytical balance, and particle size analysis by a TSI 3080L electrostatic classifier with a TSI 3776 ultrafine condensation particle counter.RESULTS: Dose delivery per actuation by CFC and long canister HFA powered MDIs was 13±1% and 12±1% less, respectively, at 3 ATA compared to 1 ATA. However, dose delivery by short canister HFA MDIs was not significantly changed with pressure. The geometric mean diameters of nano particles from the CFC and short canister HFA MDIs decreased from 50 nm at 0 fsw to 32 nm at 66 fsw whereas the long canister HFA aerosol diameters were not affected. The numbers of nanometer size particles delivered at 66 fsw were only 4-7% of those delivered at 0 fsw for the CFC and long canister HFA MDIs; whereas for the short canister HFAs it was 26%. CONCLUSIONS: The doses of albuterol and the sizes and numbers of aerosol particles emitted from albuterol MDIs actuated in a hyperbaric environment vary by canister type; CFC MDI loss is probably unimportant.

Longitudinal assessment of age-related change in the dental pulp chamber and age estimation using dental radiographs
Auteurs :
David Glynn Mcbride
Masquer le résumé
This dissertation presents a new and practical method of adult age estimation with successful tests of its validity and repeatability. Six qualitative criteria evident in oral radiographs were developed from 37 subjects represented on three occasions each. Age was estimated from averaged criterion scores by reduced major axis (Model II) regression incorporating longitudinal information for prediction with cross-sectional data. Spearman correlation of scores to known age was r [subscript] s = 0.82, for 45 subjects aged 17 to 86 years in an independent test set. Mean error of estimated age was 0.08 years (SD 8.3 years). In contrast, longitudinal premolar pulp chamber sizes typically showed Pearson correlations to age of r [almost equal to] -0.50, with no pattern of association by premolar type, sex, or trend over time useful in age estimation. Eleven raters with experience in skeletal analysis ranging from student to professional showed the qualitative method to be independently repeatable using only a written rubric and graphic examples. Raters' scores had Spearman correlations to age of 0.70 [lesser than] rs [lesser than] 0.85, and a mean error of 0.91 years (SD 13.7 years), in a sample of 20 subjects selected for approximately equal distribution by age and sex. Oral radiography is noninvasive, commonly available to archaeologists and routine in forensic identifications. This qualitative method is applicable in adults through age 90, and may be incorporated into existing protocols to advance assessment of population distribution and individual age.

Dimensions of nursing home care: perspectives of patients, family members, and care providers
Auteurs :
Eileen M. Jackson
Masquer le résumé
Conflict among care participants in the nursing home setting concerning the expectations for care-giving and care-seeking behavior has been well-documented. The question explored in this study is whether substantial differences exist among nurses', nurses' aides', patients' and family members' interpretations of the meaning of care, care requirements, and distress states that influence decision-making and care-seeking behaviors. A related question addresses whether other factors within the nursing home environment, such as the organizational structure of nurses' work and the functional model of care delivery influence the cultural models of care of care participants. The fit between a formal model of care, the self-care deficit nursing theory, and the actual cognition of care of patients, family members, nurses, and nurses' aides is also examined. A critical hermeneutic approach frames the ethnographic and ethnosemantic methods used to collect terms and attributes of care and to relate these to the context in which care takes place. Resulting care models are presented and compared using both taxonomic and spatial representations of data from multiple sources. The effects gender and other roles have on the particular configuration of care each participant holds in mind are compared. Critical examination of the meaning of these findings for the improvement of nursing home care is presented. A relatively consistent model of care was found to hold among three different groups of consultants from five nursing homes. Two dimensions, a home/hospital dimension, and a generalized/specialized knowledge dimension defined the spatial configuration of terms and attributes.
