Candidiasis and Other Bacterial Infections among Patients Diagnosed with Burning Mouth Syndrome.

Background and Objectives: Burning mouth syndrome (BMS) is a state in which a patient experiences intraoral burning or a dysesthetic sensation without clinically evident causative lesions in the oropharyngeal area. The disorder is linked to a variety of conditions, including dry mouth, Candida, and bacterial infections. The aim of this study was to determine the incidence of oral Candida and/or bacterial infections among patients with BMS and whether they have an effect on pain/burning and salivary flow levels. Objectives: (1) Gather patient data regarding the presence of oral infections, dry mouth, and pain levels in the morning, afternoon, and evening periods; (2) data analysis and assessment to determine medians, means, frequencies, correlations, and statistically significant differences between patient groups. Materials and Methods: Overall, 173 patients (23 males and 150 females) with BMS and 13 controls (five males and eight females) took part in the study. We measured pain/burning levels, unstimulated and stimulated salivary flow, the percentage of patients infected with Candida species and/or bacterial species, and the said species growth in Petri dishes. Results: Candida albicans was the most commonly found infection among patients with BMS (n = 28, 16.2%). Overall, 21.4% patients with BMS were diagnosed with either C. albicans or another Candida species. Enterobacter had the richest growth among patients with BMS (7.5% out of the infected 10.4% BMS patients). No statistical significance could be noted between the existence of either Candida species or bacterial species infections and changes in pain/burning and salivary flow levels. Negative correlations were noted between age and unstimulated and stimulated salivary flow, and positive correlations were noted between age and Candida andspecific bacteria species' growth levels. Conclusions: Although patients with present bacterial or Candida infections showed a marginal increase in pain/burning levels, no direct statistically significant associations could be made between the presence of Candida species or other bacteria and the symptoms among patients with BMS.

Candida species in patients with oral dysesthesia: A comparison of carriage among oral disease states.

OBJECTIVES: Oral dysesthesia (burning mouth syndrome) is characterized by a burning-like sensation of the oral mucosa. The etiology of this disorder is still unknown, however, associations with oral fungal carriage have been proposed and applied clinically. The aim of the this study was to compare oral Candida carriage in patients with oral dysesthesia with Candida carriage in patients with other commonly diagnosed oral diseases to clarify the relationship between Candida and oral dysesthesia. SUBJECTS AND METHODS: In total, 441 patients in total including 79 patients diagnosed with oral dysesthesia were included in this study. A retrospective analysis of mycological investigations undertaken in patients with clinically diagnosed oral dysesthesia compared with other oral conditions was undertaken. RESULTS: Oral carriage of Candida was found in 63.3% (50 of 79) of patients with oral dysesthesia. The frequency of carriage and oral load of Candida were not significantly increased in patients with oral dysesthesia relative to the other conditions assessed. Patients with clinical signs of fungal infection or xerostomia presented with increased carriage of Candida. CONCLUSION: There is no association between oral dysesthesia and the presence or load of oral Candida.

Salivary Flow Rate, Oral Yeast Colonization and Dental Status in Institutionalized and Non-Institutionalized Elderly

Elderly people, especially those institutionalized in long-term care facilities, are at risk of various oral diseases. The aim of the study was to determine the incidence of hyposalivation and colonization/oral fungal infection of oral cavity with yeasts, as well as dental status in institutionalized and non-institutionalized elderly. The study included 280 institutionalized and 61 non-institutionalized elderly people. Salivary flow rate, oral colonization with yeasts/oral infection and dental status were assessed and compared between the groups. The institutionalized elderly had a significantly lower salivary flow rate (p=0.035). Oral colonization with yeasts was more frequently found in institutionalized elderly (p<0.001) as compared with non-institutionalized elderly. A negative correlation was found between decreased salivary flow rate and oral yeast colonization and oral fungal infection in both the institutionalized (rs=-0.58; p<0.05) and non-institutionalized (rs=-0.52; p<0.05) groups. A significant difference in DMFT index was observed between the two groups (p<0.001). A negative correlation between decreased salivary flow rate and dental status was found in both the institutionalized (rs=-0.22; p<0.05) and non-institutionalized (rs=-0.56; p<0.05) groups. The results revealed a significantly higher level of hyposalivation and oral yeast colonization and poorer dental status in the institutionalized group as compared with the non-institutionalized group of elderly people.

Oral medicine and the ageing population.

The oral cavity is subject to age related processes such as cellular ageing and immunosenescence. The ageing population bears an increased burden of intraoral pathology. In oral medicine, the majority of presenting patients are in their fifth to seventh decade of life. In this review, we discuss the ageing population's susceptibility to mucosal disorders and the increased prevalence of potentially malignant disorders and oral squamous cell carcinoma, as well as dermatoses including oral lichen planus and immunobullous conditions. We also address the ageing population's susceptibility to oral discomfort and explore salivary secretion, ulceration and the symptoms of oral burning. Finally, we will describe orofacial pain conditions which are more likely encountered in an older population. This update highlights clinical presentations which are more likely to be encountered in the ageing population in a general practice setting and the importance of screening both new and long-term patients.

Conventional systemic treatments associated with therapeutic sites of local lesions of secondary syphilis in the oral cavity in patients with AIDS.

Patients with HIV infection may develop common diseases with atypical clinical features. HIV infection can change the classic clinical course of syphilis and increase the incidence of malignant syphilis. Malignant syphilis is a rare subtype of secondary syphilis that presents special clinical and histological features and has been associated with several processes characterized by variable degrees of immunosuppression. It is necessary to consider the possibility of this entity in the differential diagnoses in HIV-infected patients with cutaneous lesions. The dental surgeon (or oral surgeon) is vital to the medical team for promoting the health and improving the quality of life of syphilis patients. A patient with HIV infection was referred to us for complaints of a white patch on the tongue, stinging and burning sensation on the tongue, loss of taste, and dryness of the mouth. On clinical examination, the patient was found to have a tabetic gait (the Prussian soldier gait) associated with Charcot arthropathy. We also identified bilateral lesions with ulceration and exposure of the tissue that were tender, characterized by discrete necrosis. The treatment that was initiated at that time involved cleaning the area with gauze to remove all the white patches, followed by rinsing with bicarbonate in water (one teaspoon of baking soda dissolved in half a glass of water) four times a day. Additionally, fluconazole (100 mg/day for 7 days) was prescribed. We diagnosed secondary malignant syphilis of approximately 5 days duration. As an adjunctive therapy, we performed low-intensity laser treatment using a GaAsAl (gallium-aluminum arsenide) laser at 790 nm. With this treatment there was progressive resolution of the lesions.

Association of oral yeast carriage with specific host factors and altered mouth sensation.

OBJECTIVES: The aim of this study was to determine if there was a significant association between the presence of altered mouth and taste sensations with oral carriage of yeasts and to assess the factors that influence the yeast carriage. STUDY DESIGN: The oral and dental status including unstimulated (USFR) and stimulated (SSFR) whole salivary flow rates of a total of 509 subjects was recorded. Saliva specimens were collected for microbiologic examination. Multiple logistic regression analysis was performed to identify any factors that were significantly associated with the prevalence of oral yeasts. RESULTS: Old age, clinical signs of oral dryness, denture wearing, and a reduction in USFR increased the prevalence of yeasts, whereas patient gender, levels of dentition, the sensation of dry or burning mouth, taste disorders, and SSFR were not associated with increased prevalence of oral yeasts. CONCLUSIONS: An increased prevalence of oral yeasts was not found to relate to changes in mouth sensation alone. Other factors, most notably patient age, the wearing of dentures, clinical signs of oral dryness, and salivary flow rate under rest conditions, were, however, found to be closely associated with oral yeast carriage.

Soluble CD14 and toll-like receptor-2 are potential salivary biomarkers for oral lichen planus and burning mouth syndrome.

Oral lichen planus (OLP) and burning mouth syndrome (BMS) are chronic conditions affecting the oral mucosa characterized by pain and burning sensation. Saliva plays a significant role in the maintenance of physical and functional integrity of normal oral mucosa. Identification of potential "salivary biomarkers" for early diagnosis and/or monitoring of human diseases is being explored. We investigated the soluble forms of innate immune associated proteins CD14 and toll-like receptor-2 in unstimulated whole saliva (UWS) as potential biomarkers for OLP and BMS. Our results suggest that the levels of sCD14 and sTLR-2 in UWS were upregulated in OLP and BMS respectively. In addition, oral epithelial cells in the saliva of patients with OLP and BMS exhibited elevated levels of CD14 mRNA and decreased levels of TLR-2 mRNA. Interestingly, presence of co-existent oral candidiasis nullified these changes.

Burning mouth syndrome: clinical profile of Brazilian patients and oral carriage of Candida species.

Burning mouth syndrome (BMS) is a complex disease of unknown cause. It is characterized by a burning sensation in the oral mucosa, notwithstanding its clinical normal aspect. BMS is particularly seen in postmenopausal women. The purpose of this study was to investigate this syndrome on a clinical basis and, in addition, to analyze its possible relation to the frequency of Candida species. Thirty-one patients (28 women and 3 men; 13 Caucasians and 18 non-Caucasians; mean age = 61.3, range 30-85 years) were evaluated. Most patients (80.6%) were under long-term medication, antihypertensive, ansiolitic and antidepressant drugs being the most used. Burning mouth complaint was associated with other secondary oral complaints in 83.8% of the cases. Tongue was the most commonly affected site (70.9%), followed by the vermillion border of the lower lip (38.7%) and hard palate (32.2%). The association of the burning sensation with oral cancer (cancer phobia) was reported by 67.7% of the patients. Haematologic examination (hematocrit, haemoglobin and fasting blood glucose level) revealed 2 cases each of anemia and type 2 diabetes. Local factors, tooth extractions and dentures wearing, were associated with the onset of symptoms in 35.5% of the cases. Daily activities were changed as a consequence of BMS in 29% of the patients. Among the species of the genus Candida, C. albicans was the most frequent in BMS patients (9 - 29.03%) and controls (12 - 38.70%), followed respectively by C. parapsilosis (2 - 6.45% and 0 - 0%); C. tropicalis (1 - 3.22% and 2 - 6.45%); C. krusei and C. kefyr (1 - 3.22% and 0 - 0%). Therefore, such difference did not reach valuable results. In conclusion, these data were similar to those reported in other studies. The highlights of the present findings were the possible relation of BMS with chronic drug use, depression, menopause and cancer phobia. No association was found between BMS and the prevalence of Candida species.

A Síndrome de ardência bucal (SAB) é uma doença complexa, de etiologia desconhecida. Caracteriza-se por uma sensação de queimação na mucosa bucal, não obstante seu aspecto clínico normal, sendo bastante freqüente em mulheres após a menopausa. O propósito deste estudo foi o de investigar a SAB em bases clínicas e, em adição, analisar sua possível relação com a freqüência de espécies do gênero Candida isoladas da cavidade bucal desses indivíduos. Foram estudados trinta e um pacientes, 28 mulheres e 3 homens, 13 caucasianos e 18 não caucasianos, média de idade 61,3 (faixa dos 30 - 85 anos). A maioria deles (80,6 por cento) estava sob medicação por longo período. Anti-hipertensivos, ansioliticos e antidepressivos foram as drogas mais utilizadas. A ardência bucal estava associada a outras queixas secundárias em 83,8 por cento dos pacientes. A língua foi o sítio mais afetado (70,9 por cento), seguida pelo vermelhão do lábio inferior (38,7 por cento) e palato duro (32,2 por cento). A associação de sensação de ardência com câncer bucal (cancerofobia) foi referida por 67,7 por cento dos pacientes. Exames hematológicos (hematócrito, hemoglobina e glicemia em jejum) revelaram dois casos cada, de anemia e diabetes tipo 2. Fatores locais, exodontias, e uso de próteses estavam associados com o conjunto de sintomas em 35,5 por cento dos casos. Foram referidas alterações importantes nas atividades cotidianas, em conseqüência da SAB, em 29 por cento dos pacientes. Leveduras do gênero Candida foram isoladas da cavidade bucal de 45,16 por cento dos indivíduos com SAB e igualmente do grupo-controle, não constituindo dado qualitativamente importante. Dentre as espécies do Gênero Candida, C. albicans foi a mais freqüente (9 - 29,03 por cento e 12 - 38,70 por cento), seguida de C. parapsilosis (2 - 6,45 por cento e 0 - 0 por cento), C. tropicalis (1 - 3,22 por cento e 2 - 6,45 por cento), C. krusei e C. kefyr (1 - 3,22 por cento e 0 - 0 por cento).

Causative or precipitating aspects of burning mouth syndrome: a case-control study.

BACKGROUND: On causative or precipitating causes of burning mouth syndrome (BMS), there is a lack of consensus. In this prospective case-control study, we compared clinical features and laboratory aspects to evaluate the association of the proposed causative/precipitating factors of BMS. METHODS: A total of 61 BMS patients and 54 control subjects underwent several evaluations: rest and stimulated salivary flow rates measurements, laboratory tests, isolation of Candida species, assessment of parafunctional activities, detection of anxiety and depression by means of the Hospital Anxiety and Depression Scale. Odds ratio and 95% confidence interval were calculated to compare the variables. RESULTS: No statistically significant differences were found with regard to the tested variables except for anxiety and depression. CONCLUSIONS: The results of this study seem not to support a role for the usually reported causative or precipitating factors of BMS and efforts should be addressed towards different aetiologies including possible neuropathic mechanisms of BMS.

Helicobacter pylori associated with glossitis and halitosis.

BACKGROUND: Helicobacter pylori is a curved microaerophilic Gram-negative bacterium considered as a risk factor for gastric cancer. The aim of this study was to find an association between burning sensations, acid taste, halitosis, and lingual hyperplasia with the effect of H. pylori on the mouth. MATERIALS AND METHODS: A total of 124 subjects with different gastric diseases were studied: 46 patients with burning, halitosis and lingual dorsum hyperplasia and 78 patients with other diseases. RESULTS: The detection of H. pylori in the oral cavity by histopathologic diagnosis and molecular biology was confirmed in 40/46 (87%) patients with burning, halitosis, and lingual hyperplasia, and in 2/78 (2.6%) subjects with other diseases. Chi2: 91.26 (p < .001) Mantel-Haenszel. CONCLUSION: This trial showed an association between H. pylori and burning, halitosis, and lingual hyperplasia, and further considered this bacterium a risk factor for gastric infection.

Candida-induced stomatopyrosis and its relation to diabetes mellitus.

BACKGROUND: Glycaemic disorders and oral candidosis can be accompanied by burning mouth sensations. However, no clear relation between all three disorders is known. METHODS: Seventy-two native Upper-Austrians with burning mouth sensations were examined and smears for Candida estimation were taken from the spots where the sensations were felt. All patients with previously unknown diabetes mellitus (DM) were subjected to an oral glucose tolerance test (OGTT). Use of glucocorticoid-containing anti-asthmatic sprays and the body mass index (BMI) were determined. RESULTS: Of the examined non-inhalers of sprays, 52% had increased candidal density. A correlation between that increase and type 2 DM was found. The burning sensations in all patients with increased candidal density subsided completely after anti-mycotic therapy. CONCLUSION: The perception of burning sensations was hypothesised to occur via stimulation of the capsaicin (vanilloid) receptor by Candida metabolites. The Candida-induced stomatopyrosis should be regarded as a single symptom indicating (predisposition to or established) type 2 DM in non-inhalers of the concerned population.

Helicobacter pylori colonization of tongue mucosa--increased incidence in atrophic glossitis and burning mouth syndrome (BMS).

Nested polymerase chain reaction (PCR) was performed to detect the presence of Helicobacter pylori in tongue mucosa in 268 patients divided into four groups according to their diagnosis: 87 with atrophic glossitis, 37 with benign migratory glossitis and 144 with burning mouth syndrome (BMS). The latter group was subdivided according to anatomic site of burning sensation: subgroup A (54 patients) with complaints limited to tongue and subgroup B (90 patients) with burning sensations in other parts of oral mucosa. H. pylori was found in 43 samples (16%). Bacteria were significantly less present in tongue mucosa affected with benign migratory glossitis compared with atrophic glossitis and BMS (P=0.025). This difference was more obvious when compared with atrophic glossitis only (P=0.006). Mucosal changes in these conditions might make the oral environment more acceptable for H. pylori colonization compared with normal mucosa, and this mechanism may play a role in its oro-oral transmission.

Growth of the fungal pathogen Candida in parotid saliva of patients with burning mouth syndrome.

Subclinical Candida infection has been suggested as one of the aetiological factors in patients with burning mouth syndrome (BMS). In order to investigate the possible factors which contribute to the relatively high isolation rate of Candida in BMS, parotid saliva samples (20 in toto) from patients with this condition were collected and the growth of Candida in each sample dynamically observed using a computerized turbidometric assay system. A total of thirteen parotid saliva samples obtained from healthy individuals served as normal controls. The results showed no significant growth differential within the test and control saliva samples, when a single isolate each of Candida albicans and Candida tropicalis were cultured for 24 h, at 37 degrees C. A single isolate of Candida glabrata tended to grow better in the saliva from BMS patients than the controls. These results indicate that the composition of saliva may be a contributory factor for the high isolation rate of Candida in saliva of BMS patients.

Oral carriage of Candida species and coliforms in patients with burning mouth syndrome.

The oral carriage of Candida species and coliforms in a healthy adult population and a group of patients with burning mouth syndrome (BMS) was investigated. The intra-oral prevalence of Candida species and coliforms was higher in the BMS group compared with the controls. The most frequent yeast isolated from the BMS group was Candida albicans while Enterobacter and Klebsiella species were the most prevalent coliforms. The possible reasons and the significance of the above findings are discussed.

Burning mouth sensation associated with fusospirochetal infection in edentulous patients.

Six middle-aged and elderly edentulous, systemically ill patients complaining of burning mouth sensation had a fusospirochetal infection of the oral mucosa. Metronidazole was successful in the treatment of three of these patients.
