Dynamic In-Patient Therapy: A Team Approach, Le Van Cao

Loma Linda University Electronic Theses, Dissertations & Projects

The paper reports on the philosophy and clinical results of an individualized but concentrated team approach to hospitalized patients undergoing a psychological crisis. The team focuses on the patient’s key vital coping technique as the source of his vulnerability and assists the patient toward constructive self-understanding. The approach favors maximum therapeutic benefit from a short hospital stay. Follow-up of the first fifteen cases managed by this method discloses a significantly low percentage of relapse and rehospitalization, and demonstrates that even such relapses can be turned to therapeutic benefit.

Mandibular Repositioning With Frankel Appliance Therapy, Clark E. Schneekluth

Loma Linda University Electronic Theses, Dissertations & Projects

A sample of twelve Frankel appliance (FR-2) treated patients, in the mixed dentition stage, were selectively chosen by an orthodontist based on the Class II correction and evaluated from before treatment and end of treatment laminagraphic and lateral cephalometric radiographs. The average treatment period was 22 months (1 yr. 10 mos.). The average pre-treatment age was 9.5 years with a range from 8 to 11 years old, while the average post-treatment age was 11.3 years with a range of 10 to 13 years.

Frankel appliance therapy was the only form of mechanics used in this study.

The before treatment lateral …

Development Of A Mathematical Model Of Renal Function For Clinical Application, Barbara A. Holshouser

Loma Linda University Electronic Theses, Dissertations & Projects

This model describes the orthoiodohippurate (OIH) distribution and clearance in the renovascular system. The model is described by five compartments: the blood, left and right kidneys, bladder and the red blood cell compartment. Data for these compartments, except the RBC compartment, are collected with scintillation detectors monitoring OIH tagged with 1-131 as the radiopharmaceutical passes through each compartment. Time/ activity curves are plotted for the data and used as inputs to the model parameter estimation routine. The compartments are described by a set of first order ordinary differential equations solved using the Adam's methods. For parameter estimation, an iterative predictor-corrector …

Implementing Augmentative Communication For Aphasic Patients In Convalescent Facilities, Susan H. Mcgann

Loma Linda University Electronic Theses, Dissertations & Projects

A one-hour Blissymbol in-service training program was developed for presentation to staff members of a skilled nursing facility. The purpose was to determine whether the program would produce significant learning to justify its use in similar facilities to bridge the communication gap between nonspeaking/nonwriting aphasic patients who communicate with Blissymbols and their direct care personnel as well as family members and others who are significant in their lives.

After development, the in-service program was given two "dry-runs" in skilled nursing facilities similar to the "study facility". It was then revised to improve clarity and to make it fit within time …

A Comparison Of Level Of Knowledge In Communicative Disorders Between Senior Medical Students And Senior Speech-Language Pathology Students, Cynthia R. Huffman

Loma Linda University Electronic Theses, Dissertations & Projects

In California, physicians are required to "refer and prescribe the extent and duration of hearing, speech and equilibratory services for their patients who are beneficiaries of the state's Medicaid program (Title 22, Division 3 and 4 of the Medi-Cal Utilization Controls #51096). The present study was designed to determine whether senior medical students have knowledge in all areas of Communicative Disorders which is equal to or better than that of the senior speech-language pathology students to whom they will "prescribe" when they enter professional practice.

The study was conducted with the cooperation of students from the Loma Linda University School …

Conformational Analysis Of Nonsteroidal Estrogen Analogs, Robert N. Spady

Loma Linda University Electronic Theses, Dissertations & Projects

In target tissue, estrogens initiate a series of events, ending in protein synthesis, by binding to a cytoplasmic receptor. Once the estrogen binds, the receptor complex is activated--a process including dimerization of the estrogen complex with another subunit. In order to study the possible receptor-ligand interactions, conformational analysis was performed on several nonsteroidal estrogen analogs, using the CAMSEQ8 molecular mechanics program.

The probability that a molecule will exist in a given conformational energy well depends both on the energy and the shape of the well. A method has been previously worked out to calculate probabilities using both of these variables, …

A Correlation Of Subjective Ranking Of Facial Esthetics And The Golden Section Analysis, Timothy Robin York

Loma Linda University Electronic Theses, Dissertations & Projects

The objective of this study was to determine if faces which fit the golden sections as proposed by Ricketts were considered more esthetic to the layman than faces which did not fit the golden sections as well.

Frontal facial photographs of 92 individuals from the normal occlusion sample of Andrews were measured for facial proportions according to Ricketts application of the golden section. Seven facial proportions were computed from the photographs. Ten photographs were selected, five of males and five of females, representing a range of mean percent deviation from the golden section proportion (1.618). Randomly arranged sets of these …

The Effect Of Fetal Age On Skin Permeability In Guinea Pigs, Benita Stiles Whitted

Loma Linda University Electronic Theses, Dissertations & Projects

Preliminary investigation has indicated large decreases in fetal skin permeability during the latter half of gestation (Parmley and Seeds, 1970; Treager, 1966). The purpose of this study was to demonstrate the degree of skin permeability in fetal guinea pigs at various gestational stages. The test hypothesis was that these skins would show a significant decrease in permeability to tritiated water when tested at time increments through out the latter half of gestation.

In vitro skin permeability to tritiated water was measured in samples from 22 guinea pig fetuses. Gestational age ranged from 30 to 65 days in increments of five, …

Lingual Function And Articulatory Competence, Donna E. Swenson

Loma Linda University Electronic Theses, Dissertations & Projects

Dworkin (1979) states that, of the 2.5 million children and young adults in the United States with a communication problem, 60% have a functional articulation disorder for which no psychologic or physical problem can be found. The oral mechanism examination is an established part of a speech and language examination for testing these children, and the tongue is the most important organ for speech (Johnson, Darley, and Spriestersbach, 1963). However, no conclusive rationale for the procedure or objective lingual measurements have been established. This research, therefore, was designed as a pilot study to investigate whether lingual structure and function are …

The Effect Of Self-Help Support Groups On Self Esteem And Blood Glucose In Young Insulin-Dependent Diabetics, Linda L. Woertz

Loma Linda University Electronic Theses, Dissertations & Projects

Successful adaptation to diabetes is probably a function of many factors: the stress involved, the rewards, the motivation of the individual, and the self concept. The more optimal the self concept the more optimal the behavior may be. By helping the patient shape a positive self concept, a base can be built for blood glucose control (Bruhn, 1977, pp. 93-97). One method of improving self concept or self esteem may be through the development of self-help support groups for diabetics.

The purpose of this study was to evaluate the effect of self-help support group intervention on the levels of self …

Easily Administered Recognition Of Linguistically-Handicapped Youngsters, Robin J. Webb

Loma Linda University Electronic Theses, Dissertations & Projects

This study investigates the feasibility of involving parents as evaluators using an objective screening test for their children who are 36 to 42 months of age. A more available and nonthreatening assessor is needed as physicians, dentists and other allied health professionals who are typically used to screen children for speech, language and hearing have not been effective with this age group. This is partially due to the limited contacts they have with these children and the environmental limitations for eliciting an adequate speech and language sample (Behrens, 1978; Webb, 197B; Hirsch, 1981).

An objective-type screening instrument has been designed …

Blood Reservoir Function Of The Fetal Guinea Pig Liver, Gregory A. Roda, Raymond D. Gilbert, Gordon G. Power

Loma Linda University Electronic Theses, Dissertations & Projects

To determine of the fetal liver functions as a blood reservoir, we measured liver blood volume under normal conditions and after hemorrhage and volume loading. Nineteen pregnant guinea pig sows and 54 near-term fetuses were injected intravenously with ⁵¹Cr-labeled red cells while the fetuses remained in utero. Ninety seconds later a 0.5-1.0 g sample of liver was garroted with a sharp wire into a tared tube with minimal blood loss. A blood sample was taken to measure counts per ml of blood, the fetus killed and the remainder of the liver weighed. Blood volume of the liver and body …

Healing Following Two Different Surgical Approaches To Treating Deep Periodontal Intraosseous Defects, A. Durwin H. Chamberlain

Loma Linda University Electronic Theses, Dissertations & Projects

Surgical treatment of deep periodontal pockets associated with intraosseous defects has traditionally been performed either with or without resection of the osseous defect. A non-resective approach may provide more gain of attachment while a resective approach may give better pocket reduction. The increased pocket reduction following osseous resection is probably accomplished at the expense of some attachment loss in areas involved by the surgical procedure. Previous studies have compared periodontal surgery with and without osseous resection (i.e. Rosling et al. 1976, Knowles et al. 1979 and Smith et al. 1980). However, the effect of osseous resection does not seem to …

Loma Linda University Electronic Theses, Dissertations & Projects

Data on actual labor time can be utilized as an effective management tool. With labor cost representing about 50 percent of direct cost in food service, it is essential to examine how labor time is being utilized.

A continuous time study was conducted to determine the total labor time for the production of eight vegetarian entrees. The two work areas observed were the ingredient assembly area and the cooks' production area. This labor time was recorded by Work Functions to find the dis- tribution of labor time. Data from the observations were compiled using an Apple II computer system. Reports …

An Investigation Of Selected Caring Behaviors In A Hong Kong Chinese Village, Mary Jon Waldron

Loma Linda University Electronic Theses, Dissertations & Projects

The lack of scientific information regarding caring beliefs, expectations, and behaviors in the Chinese community of Hong Kong was the problem underlying this descriptive study. A knowledge of caring behaviors as they routinely occur within a culture can provide a basis for the development of professional nursing care that is meaningful for the people of that culture. The purpose of the study was to obtain the opinions of the residents of a Hong Kong Chinese village regarding current beliefs and practices relating to touch, surveillance, health counseling, and special ethnocare techniques. Representatives of twenty families were interviewed with the assistance …

A Comparison Of Two Rapid Palatal Expansion Appliances And Their Effect On Palatal Cross-Sectional Area, William D. Scott

Loma Linda University Electronic Theses, Dissertations & Projects

Two rapid palatal expansion appliances, acrylic-free and acrylic-reinforced, were compared for their effect on the cross-sectional area of the palate. Two groups, twenty-five patients in each, were selected so that they would match as closely as possible with regards to age and sex distribution. The pre-treatment and post-treatment maxillary models were duplicated, and this duplicate model was then trimmed in a specific manner to allow the cross-sectional area between the first permanent molars to be compared. The results indicate that there is no difference, at the five percent level of significance, between these two appliances. It is concluded that the …

The average time period of the post-treatment evaluation period was 5.7 years after the end of active therapy. The patients' ages ranged from 8.4 to 13.3 years at the beginning of activator treatment.

In the correction of the Class II malocclusion, no other form of orthopedic mechanics were utilized in this sample. In some cases full banding was used to align and level the arches prior to the activator therapy. …

Evaluating The Aural/Oral Skills Of Children Identified By The Slingerland Pre-Reading Screening Procedures, Sandra L. Singleton

Loma Linda University Electronic Theses, Dissertations & Projects

Research tends to confirm the concept that it is imperative to diagnose learning disorders early and start remediation immediately. Slingerland (1977) developed an assessment tool, which reportedly aids in the identification of remediational needs before a child has experienced failure. This screening device was designed to "show modality weaknesses that call for specific instruction to prevent early failare" (Slingerland, 1977). All of the subtests from the Pre-Reading Screening Procedures are cross-modality tasks because the testing of a modality, "Auditory" or "Visual", requires the use of one or two other modalities (motor or speech) to generate a response. In order to …
