Randomized controlled trial of the effectiveness of three different oral moisturizers in palliative care patients.

Most patients in palliative care have problems with dry mouth caused by medication or as a direct result of their condition. Dry mouth may cause problems that affect the primary disease negatively and contribute to poorer quality of life in palliative patients. This randomized controlled trial compared the efficacy of three different oral moisturizers: 17% watery solution of glycerol; oxygenated glycerol triester (marketed as Aequasyal in Europe and as Aquoral in the USA); and a newly developed product, Salient. Of the three products, glycerol provided the best relief from xerostomia directly after application, but had no effect after 2 h. By contrast, the effects of Aequasyal and Salient were largely maintained over the same period. The findings for oral discomfort and pain and speech problems showed a similar pattern. Despite its poor effect after 2 h, patients preferred glycerol over Salient and Aequasyal, probably because of the unpleasant taste of Aequasyal and the consistency and mode of application of Salient. Within the limitations of this study, none of the three products tested was found to be clinically completely adequate. However, the glycerol solution was preferred by this group of patients, and its short-lived effect can be compensated for by frequent applications.

Effect of glycerol on reconstructed human oral mucosa.

The majority of severely ill patients experience dry mouth. For institutionalized patients, this condition is commonly treated using glycerol as a lubricant. However, because of its possibly desiccating effect, some countries do not advocate the use of glycerol. This study aimed to investigate dose-dependent effects of glycerol on homeostasis and tissue integrity of in vitro-reconstructed normal human buccal mucosa (RNHBM). Primary keratinocytes and fibroblasts were isolated and expanded from biopsies of mucosa from eight healthy volunteers. Ninety-six samples of RNHBM were prepared and exposed for 24 h to 17%, 42.5%, or 85% glycerol, or to distilled H2 O (control). Sections were stained with haematoxylin and eosin (H&E) to evaluate epithelial thickness or used for immunohistochemistry to measure expression of Ki67 (proliferation), cleaved caspase-3 (apoptosis), and E-cadherin (tissue-integrity). Positive cells and cell layers, as detected by immunohistochemistry, were counted. Epithelial thickness, proliferation, and apoptosis were significantly increased by exposure to 42.5% and 85% glycerol. No significant differences in apoptosis or proliferation were found between controls and RNHBM exposed to 17% glycerol. E-cadherin expression was not significantly affected by exposure to any of the concentrations of glycerol tested. This study shows that glycerol affects tissue homeostasis, but not tissue integrity, of RNHBM at glycerol concentrations above 42.5%.

End-of-life palliative oral care in Norwegian health institutions. An exploratory study.

OBJECTIVE: To explore circumstances surrounding procedures and knowledge regarding oral care for terminal patients in Norwegian healthcare institutions. METHODS: A questionnaire was distributed to randomly selected hospitals (n = 19) and nursing homes (n = 57) in central and rural parts of Norway. The questionnaire included three closed-ended and three open-ended questions about oral care for terminal patients. If procedures existed, the respondents were asked to enclose or describe them. RESULTS: The response rate was 84% for hospitals and 79% for nursing homes. Of the responding institutions, 25% had no oral care procedures, nor did 48% recognise their importance. Insufficient knowledge about oral care was reported by 39%. Twenty-one different procedures were identified, and a great number of oral care products used. The most common was glycerol, used by 36% of the institutions. Only 2% used a concentration below 30% - the limit above which the glycerol has a desiccating rather than a moistening effect. The most common patient complaint was dry mouth (49%), followed by plaque, food particles and fungus infections, each experienced by 19%. The most common problem for the personnel was lack of knowledge (43%) and patient cooperation (38%). CONCLUSIONS: Some terminal patients do not receive adequate palliative oral care in Norwegian healthcare institutions. Those that do are exposed to a great number of undocumented procedures and sometimes harmful products. There is a need for evidence-based procedures for oral care for terminally ill patients in health institutions, establishing interprofessional palliative healthcare teams and in particular improved training of the nursing staff.

HIV/AIDS-related attitudes and oral impacts on daily performances: a cross-sectional study of Sudanese adult dental patients.

BACKGROUND: Few studies have investigated the relationships between HIV-related knowledge, fear of contagion in dental environments and Oral Impacts on Daily Performance (OIDP) among dental patients. Our objectives were to investigate the associations between HIV-related knowledge and fear of contagion in dental environments and OIDP among dental patients, and to evaluate whether those associations were modified by the frequency of dental service attendance. METHODS: A total of 1262 patients (mean age 30.7 years, 56.5% females) were recruited from the Khartoum Dental Teaching Hospital and the University of Science and Technology during March-July 2008. The participants underwent a full-mouth oral clinical examination and completed an interview in a face-to-face setting. RESULTS: Of the study participants, 41.4% had visited a dentist at least twice during the last 2 years, 96.2% had caries experience (DT > 0) and 79.1% reported oral impacts (OIDP > 0). The most frequently reported oral impacts were problems eating, sleeping and cleaning teeth. In total, 26.3% of the participants had HIV transmission knowledge, 75.6% knew people with HIV/AIDS and 58.7% perceived a high risk of cross-infection in dental environments. After adjusting for sociodemographic characteristics, frequency of dental service attendance and caries experience, patients who had high HIV-related information exposure, a positive attitude toward people with HIV/AIDS and a high perceived risk of cross-infection were more likely to report oral impacts, whereas patients who knew people with HIV/AIDS were less likely to report oral impacts. The association between OIDP and HIV transmission knowledge was modified by frequency of dental service attendance. CONCLUSIONS: Dental patients who were informed about HIV and had a high HIV/AIDS risk perception were more likely to report impaired oral health-related quality of life than their less informed counterparts and those who perceived a low risk of contagion. The effect of HIV transmission knowledge on oral impacts was influenced by frequency of dental service attendance.

A Longitudinal Follow-up of Autoimmune Polyendocrine Syndrome Type 1.

CONTEXT: Autoimmune polyendocrine syndrome type 1 (APS1) is a childhood-onset monogenic disease defined by the presence of two of the three major components: hypoparathyroidism, primary adrenocortical insufficiency, and chronic mucocutaneous candidiasis (CMC). Information on longitudinal follow-up of APS1 is sparse. OBJECTIVE: To describe the phenotypes of APS1 and correlate the clinical features with autoantibody profiles and autoimmune regulator (AIRE) mutations during extended follow-up (1996-2016). PATIENTS: All known Norwegian patients with APS1. RESULTS: Fifty-two patients from 34 families were identified. The majority presented with one of the major disease components during childhood. Enamel hypoplasia, hypoparathyroidism, and CMC were the most frequent components. With age, most patients presented three to five disease manifestations, although some had milder phenotypes diagnosed in adulthood. Fifteen of the patients died during follow-up (median age at death, 34 years) or were deceased siblings with a high probability of undisclosed APS1. All except three had interferon-ω) autoantibodies, and all had organ-specific autoantibodies. The most common AIRE mutation was c.967_979del13, found in homozygosity in 15 patients. A mild phenotype was associated with the splice mutation c.879+1G>A. Primary adrenocortical insufficiency and type 1 diabetes were associated with protective human leucocyte antigen genotypes. CONCLUSIONS: Multiple presumable autoimmune manifestations, in particular hypoparathyroidism, CMC, and enamel hypoplasia, should prompt further diagnostic workup using autoantibody analyses (eg, interferon-ω) and AIRE sequencing to reveal APS1, even in adults. Treatment is complicated, and mortality is high. Structured follow-up should be performed in a specialized center.
