Investigation Of The Relationship Between Pelvic Tilt And Unilateral Sacroiliac Pain, Beth-Anne Moody Jones

Rehabilitation Sciences Theses & Dissertations

Low back pain is the nation's leading cause of disability. Differential diagnosis of a low back injwy can be complicated and uncommon disorders can be overlooked. Many of the signs and symptoms related to low back pain may in fact be caused by sacroiliac dysfunction. Reliability of the current clinical tests for detection of sacroiliac involvement has been of concern. Recently more focus has been given to the use of pelvic tilt measurement as a source of clinical information on the sacroiliac joint. The purpose of this study was to examine the correlation of unilateral sacroiliac dysfunction with asymmetrical changes …

A Comparative Analysis Of Prospective Nursing Patient Classification And Retrospective Nursing Patient Classification, Dana Larmore Hlusko

Nursing Theses & Dissertations

Nursing patient classification systems have been in use in some form since Florence Nightingale first arranged her patients in wards (Giovanetti, 1978). Prospective classification systems which have been implemented in hospitals now generate billing information, staff budgets and long-range financial forecasts (Giovanetti, 1978; Alward, 1983; Edwardson and Giovanetti, 1987). Quantitative analysis using at-test indicated a significant difference in mean acuity scores in the prospective and retrospective data which pointed to a retrospective system as being more appropriate for billing, budgeting and finance decisions. Spearman's correlation analysis did not demonstrate a strong correlation between any indicators or with total acuity. Several …

The health care industry faces increasing financial pressures due to fundamentally new forces that affect the very viability of many health care organizations. Such pressures include prospective payment, …

Determination Of Pancreatic And Salivary Amylase By Enzyme Immunoassay And Their Prevalence In Hyperamylasemic Patients, Sabdra Borgens Ward

Theses and Dissertations in Biomedical Sciences

Currently, amylase determinations are nonspecific for the organ source and are based entirely on the enzymatic properties of amylase to produce a measurable product or byproduct. The determination of pancreatic amylase is important in the diagnosis of acute pancreatitis. Most commercially available tests for amylase employ the measurement of the change in NADH absorbance at 280 nm or of the p-nitrophenol released from a maltotetrose substrate. These are nonspecific measurements of pancreatic amylase and often necessitate other tests to be run such as a serum lipase.

The two predominant isoenzymes of amylase are pancreatic (p-amylase) and salivary (s-amylase); the most …

Regulation Of Dental Hygienists: Its Effect On Disciplinary Action And Opinions Of Regulatory Board Members In The United States And Canada, Jodie A. Mueller

Dental Hygiene Theses & Dissertations

An Assessment Of Four-Hour Sample Durations Used To Determine Full-Shift Noise Exposures In A Foundry, Vince Marlo Fleming

Community & Environmental Health Theses & Dissertations

Full-shift sampling, usually eight hours, is traditionally performed to assess daily occupational noise exposure. This sampling approach is inefficient, and costly for repeated, long-term exposure evaluations. This study assessed the use of four-hour sample durations and subsequent data analysis to determine daily occupational noise exposures in a foundry. The four-hour sample durations were extracted from full-shift samples and analyzed on their ability to provide valid data for estimating mean daily noise exposure levels without significantly affecting sampling precision or accuracy. Results of this study indicate four-hour sample durations can be used successfully to estimate full-shift noise exposures provided certain criteria …

This study involved the development of an instrument to identify and quantify sources of stress within a give profession. The industrial hygiene profession was chosen, though the method can be, and has been, used to evaluate stress in other groups of individuals. The method involved the identification of the most significant sources of stress by surveying a small number of the …

Immunologic Evaluation Of Ectopic Gestation, Tawfig Amin Nasser

Health Services Research Dissertations

Ectopic gestation is an error in the implantation site of the blastocyst. Extrauterine implantation presents a unique environment since the protective features of the uterus are absent. This study is an investigation into the immunoregulatory differences that may develop as a result of a change in the feto-maternal junction.

The effects of female plasma on one-way mixed lymphocyte cultures and mitogen-stimulated cultures, anti-paternal lymphocytotoxicity, and lymphocyte phenotypes were determined on normal, ectopic and non-pregnant females. The results indicated that pregnant female plasma enhanced the response of autologous lymphocytes to spouse and male control lymphocytes. Enhancement was not seen in the …

An Analysis Of Mitochondrial Dna In Rett Syndrome And Other Neurodegenerative Disorders, Catherine Erickson Burgess

Theses and Dissertations in Biomedical Sciences

Mitochondrial dysfunction resulting from mutations on mitochondrial DNA (mtDNA) is being recognized in a growing spectrum of diseases. These diseases, resulting from single base mutations, large deletions, or insertions, have been largely neuromuscular in origin. However, as an understanding of the effects of mtDNA mutations progresses, attention is now focusing on neurodegenerative diseases. Rett Syndrome (RS), a progressive neurodegenerative disease with predominantly female cases, demonstrates morphologic mitochondrial changes, mitochondrial enzyme deficiencies and maternal inheritance (characteristic of mtDNA diseases). No investigation of mtDNA involvement has been previously conducted and, to date, no biological marker exists for this disorder.

Our preliminary studies …
