Since 1979, 32 behavioral studies using monaural stimulation elicited an hemispheric asymmetry confirming the findings of 74 investigations published between 1967 and 1979, which were compiled by Henry, 1979. 13 psychophysiological studies also using monaural stimulation have been added; they reach the same conclusion.
Since 1967, 74 studies reported in the literature using monaural stimulation elicited an hemispheric asymmetry, confirming original findings from dichotic listening studies.
Radionuclide studies in a renal-transplant patient with congestive heart failure suggested vascular steal from the renal allograft by a contralateral femoral arteriovenous fistula. These reliable, noninvasive diagnostic procedures have potential use in similar settings to evaluate allograft perfusion and function. Correction by removal of the fistula was demonstrated.
Diagnostic guide lines are presented to help the general practitioner to correctly differentiate the "simple" from the "difficult" case of malocclusion. These aids to diagnosis are set out in an orderly fashion to encourage a closer and more systematic examination of the bite of every patient presenting for dental treatment. Certain types of appliances are suggested as adequate to cope with the malocclusion, once the correct diagnosis has been made.

Coping with patient deaths and family bereavement has received minimal attention in dental education and literature. This study was conducted to determine how frequently dentists experience patient deaths, how they cope with the knowledge of a patient's death, and if they demonstrate need for emphasis in the dental curricula in the areas of death and bereavement. A survey adapted from Chiodo and Tolle (1988) was sent to all 2091 dentists in the State of Kentucky. The response rate was 47.68% (997 returned surveys). Findings include: (1) General dentists (GDs) have a significantly higher number of patients who die each year than do specialists (S) (GD = 7, S = 1.5); (2) coping behaviors range from sending sympathy cards (63%) to attending the funeral (23%); (3) patient deaths cause stress, most stress occurring when patients die unexpectedly; (4) the greatest stress was encountered when talking with the patient's family; and (5) most dentists (58%) believed that bereavement education should occur in dental school. In conclusion, this research adds to the limited literature on appropriate coping behaviors by dentists when patients die and suggests that death and bereavement education should occur in the dental school setting to prepare practicing dentists for coping with patient loss due to death, and to provide family bereavement support mechanisms.
Dental care for most medically compromised patients can be accomplished if dentists understand the patients' specific medical conditions and use standard conservative behavioral or physical modifications to prevent complications from occurring. However, in patients who have certain types of neurological conditions, specifically Alzheimer's disease and other types of dementia, dental management typically presents a greater challenge, because, in most kinds of dementia, patients are unable to follow directions or cooperate with simple instructions such as opening their mouths or holding their heads still. This report describes a three-year retrospective chart review of patients, diagnosed with a neurologic impairment, who underwent intravenous sedation at the Department of Veterans' Affairs Medical Center in Lexington, Kentucky. The goals of this review were to investigate the average doses of commonly used sedative agents, review complications as a result of the sedation, and comment on the safety of intravenous sedation as a means to treat elderly adults with a neurological disability.
The purpose of this study was to develop coils for MR imaging of the head and neck region, with the aim of improving sensitivity and coverage. A head and neck phased array coil was constructed and compared with volume and temporomandibular joint surface coils for sensitivity and coverage in phantom studies. An algorithm was implemented to correct for the nonuniformity in the surface coil reception profile. Its application to high-resolution T2-weighted imaging in healthy volunteers was investigated.
Alzheimer's disease (AD) is the most prevalent type of dementing illness affecting over four million Americans. It typically occurs after age 60, and prevalence increases with advanced age. As the adult population increases, a greater number of patients with a diagnosis of AD will require dental care. This article reviews the oral and systemic clinical findings seen in AD patients and current medical treatment. Some general and specific suggestions for dental management are presented, including guidelines for restraint and sedation use. Finally, some helpful, adaptive oral devices are recommended for use by caregivers of patients unable to provide for their own daily oral hygiene. Dental providers can and should be willing to make oral care available to patients with a diagnosis of AD. Despite the difficulties involved, the need will continue to be great, and the gratification in caring for these patients makes it worth the effort.
