Independent older adults perspectives on oral health.

OBJECTIVES: The purpose of this study was to explore oral health experiences from the perspective of older adults' living in community dwellings. The two objectives of this study were to identify facilitators and barriers to oral health care, and to determine how utilization of oral health services compares to utilization of other healthcare services. METHODOLOGY: An interpretive descriptive methodology was employed with a purposive sample of 12 adults, aged 70 years or older. The inclusion criterion was English-speaking seniors residing in community dwellings. Community dwellings were defined as any housing outside of long-term care or other supportive living facilities. Semi-structured interviews were 30-80 min, audio-recorded and transcribed verbatim. Three researchers participated in the comparative analysis process to develop codes, generate categories, interpret patterns and construct themes. RESULTS: Three central themes surfacing from the data were as follows: life course influences on oral health, transparency in delivery of oral health services and interrelationships between oral health and overall health. CONCLUSIONS: Older adults in this study emphasized the value of establishing collaborative and trusting relationships between oral health practitioners and older adults. Oral health practitioners should be clear and transparent when communicating information about oral health costs and be cognizant of different circumstances from childhood to older adulthood that inhibit or promote routine utilization of oral health services. Including oral health services as part of interdisciplinary care teams could help promote understandings of the reciprocal relationship between oral health and general health and improve oral health status for older adults.

Building professional competence in dental hygiene students through a community-based practicum.

OBJECTIVES: As Canadians age, there is an increased need for oral health professionals specializing in services for this unique population. Dental hygiene students require exposure to this population to develop professional competencies. This study investigated the dimensions of professional competence that were developed through a practicum for dental hygiene students in long-term care settings while working with older adults. METHODS: Nine dental hygiene students were recruited across two cohorts. All students completed reflective journals describing their practicum experiences. Five students also participated in an audio-recorded focus group and completed a pre-focus group questionnaire. Additionally, the practicum course coordinator completed an audio-recorded interview. Transcripts and journals were coded using a constant comparative approach and themes were identified. RESULTS: Students described developing client-focused skills, such as effective verbal and non-verbal communication with older adults with dementia. Context-based learning was also a large part of the competency development for the practicum students. Understanding the care environment within which these residents lived helped students to understand and empathize why oral health may not be prioritized. Students also developed an understanding of the work of other health professionals in the settings and improved their abilities to communicate with other healthcare providers. However, students recognized that the utility of those interprofessional skills in private practice may be limited. CONCLUSION: Dental hygiene students developed personal and ethical competencies during practicum that are highly transferrable across professional settings. Exposure of students to older adult populations in long-term care may increase the likelihood of dental hygienists working in this area.

Candidatus Mycoplasma haematoparvum and Mycoplasma haemocanis infections in dogs from the United States.

Mycoplasma haemocanis (Mhc) and Candidatus Mycoplasma haematoparvum (CMhp) have been described in dogs. Historically, microscopic visualization of hemotropic Mycoplasma spp. has occurred most often in immunocompromised or splenectomized dogs. The aim of this study was to determine the Mhc and CMhp prevalences among dogs from the United States. Novel 16S rRNA and RNAseP gene PCR assays were used to amplify hemotropic Mycoplasma species DNA for GenBank sequence alignment. Among the study population, hemoplasma prevalence was 1.3% (7 out of 506), with Mhc and CMhp prevalences of 0.6% and 0.8%, respectively. Two of six CMhp-infected dogs were co-infected with a Bartonella sp., and a third dog was seroreactive to Bartonella henselae antigens. The prevalence of Mhc and CMhp in this study was low; potential blood donors should be screened; and dogs and people can be co-infected with hemoplasma and Bartonella spp.

An argument for dental hygiene to develop as a discipline.

UNLABELLED: The practice of dental hygiene was developed to provide oral health education and preventive oral health care, originally for children. It has grown to provide oral health services valued by a broad spectrum of society, but has not attained the desired respect and status accorded to other professional groups. OBJECTIVE: Professional disciplines link actions of practitioners with the science that is the foundation of practice. The purpose of this paper is to examine whether dental hygiene practice could benefit from pursuit of development as a discipline. METHODS: Literature on professionalization and disciplines, related to dental hygiene in general and the North American context specifically, was retrieved from databases and grey sources, such as organizational reports. Dental hygiene's current characteristics relative to a discipline were examined. RESULTS: Dental hygiene has developed some characteristics of a discipline, such as identifying a metaparadigm that includes concepts of the client, the environment, health/oral health and dental hygiene actions, with a perspective that includes a focus on disease prevention and oral health promotion. However, research production by dental hygienists has been limited, and often not situated within theoretical or conceptual frameworks. CONCLUSION: Dental hygiene draws its knowledge for practice from a variety of sources. Dental hygiene could strengthen its value to society by prioritizing development of highly skilled researchers to study interventions leading to improved oral outcomes, and transferring that knowledge to practitioners, strengthening links between practice and science. Intentional pursuit of knowledge for practice would lead to dental hygiene's eventual emergence as a professional discipline.

Irreversible silicone oil adhesion to silicone intraocular lenses. A clinicopathologic analysis.

PURPOSE: To report a newly defined complication of foldable intraocular lenses (IOLs), namely silicone oil-silicone IOL interaction. This is a complication not generally seen by the implanting cataract surgeon but, rather, at a later stage in a patient's postoperative course, by a vitreoretinal surgeon. METHODS: Three clinical case histories, including two explanted silicone IOLs, were submitted for analysis. The submitted silicone lenses were photographed under water, and the nature of the silicone oil coating was documented. RESULTS: In each instance, the silicone coating was manifest as a thick coating with droplet formation on the lens surface that was tenaciously adherent and could not be dislodged by instruments or injection of viscoelastics. CONCLUSION: The use of silicone IOLs in patients with current vitreoretinal disease or those who are at high risk for future vitreoretinal disease that may require silicone oil as part of the therapy should be reconsidered. The authors recommend that information regarding the existence and significance of this complication be printed on all silicone oil and silicone IOL packages and inserts (if not as a warning, at least as an informative comment regarding the existence of this condition). This is a rare but clinically significant complication that will affect the occasional patient treated with both of these modalities.
