The aim of this study was to evaluate the effectiveness of acupuncture in minimizing the severity of radiation-induced xerostomia in patients with head and neck cancer. A total of 24 consecutive patients receiving > 5000 cGy radiotherapy (RT) involving the major salivary glands bilaterally were assigned to either the preventive acupuncture group (PA, n = 12), treated with acupuncture before and during RT, or the control group (CT, n = 12), treated with RT and not receiving acupuncture. After RT completion, clinical response was assessed in all patients by syalometry, measuring the resting (RSFR) and stimulated (SSFR) salivary flow rates, and by the visual analogue scale (VAS) regarding dry mouth-related symptoms. Statistical analyses were performed with repeated-measures using a mixed-effect modeling procedure and analysis of variance. An alpha level of 0.05 was accepted for statistical significance. Although all patients exhibited some degree of impairment in salivary gland functioning after RT, significant differences were found between the groups. Patients in the PA group showed improved salivary flow rates (RSFR, SSFR; p < 0.001) and decreased xerostomia-related symptoms (VAS, p < 0.05) compared with patients in the CT group. Although PA treatment did not prevent the oral sequelae of RT completely, it significantly minimized the severity of radiation-induced xerostomia. The results suggest that acupuncture focused in a preventive approach can be a useful therapy in the management of patients with head and neck cancer undergoing RT.
Objective: To determine the oral status, salivary flow rate,
These data suggest that, at least in São Paulo, there is an association between OLP and HCV infection.
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.
PURPOSE: This study aimed to evaluate the efficacy of the systemic drugs thalidomide, dapsone, colchicine, and pentoxifylline in the treatment of severe manifestations of RAS. METHODS: An open, 4-year clinical trial was carried out for 21 consecutive patients with severe RAS. Initially, patients were given a 2-week course of prednisone to bring them to a baseline status. Simultaneously, one of the four test drugs was assigned to each patient to be taken for a period of 6 months. During the course of the trial, patients were switched to one of the other three drugs whenever side effects or a lack of satisfactory results occurred, and the 6-month limit of the treatment was then reset. RESULTS: The most efficient and best-tolerated drug was thalidomide, which was administered to a total of eight patients and resulted in complete remission in seven (87.5%). Dapsone was prescribed for a total of nine patients, of whom eight (89%) showed improvement in their symptoms, while five showed complete remission. Colchicine was administered to a total of ten patients, with benefits observed in nine (90%), of whom four showed complete remission. Pentoxyfilline was administered to a total of five patients, with benefits observed in three (60%), of whom one patient showed complete remission. CONCLUSION: The therapeutic methods used in this trial provided significant symptom relief. Patients experienced relapses of the lesions; however, this occurred after withdrawal of their medication during the follow-up period
The aim of this study was to assess the prevalence of factors associated with oral colonization by Candida spp. in pediatric patients with AIDS. The sample comprised of 117 children. Clinical status, medicines in use, and laboratory findings were obtained from hospital records; sociodemographic data were given by relatives. A dental examination assessed the prevalence of dental caries. The prevalence of oral colonization by Candida was 62%. Only seven children presented clinical manifestation of oral candidosis despite their high viral load index and low-for-age CD4 count. Candida colonization was directly associated with frequent use of antibiotics (prevalence ratio [PR] = 1.44), sulfa drugs (PR = 1.23), alteration in the oral mucosa (PR = 1.55), and untreated dental caries (PR = 1.93). It was inversely associated with the use of antiretroviral therapies (PR = 0.65). Candida albicans was the most frequently detected species (80%); phenotypic tests did not detect C. dubliniensis strains. This study observed a low prevalence of Candida-related oral lesions in these patients, which is compatible with the hypothesis that antiretroviral medicines may have contributed to reducing oral manifestations from Candida infection. The high prevalence of Candida colonization in HIV+/AIDS children with untreated dental caries reinforces the importance of oral health care in interdisciplinary health units that assist these patients.
OBJECTIVE: To determine the frequency of Candida spp., xerostomia, and salivary flow rate (SFR) in three different groups: patients with OLP (OLP group), patients with oral mucosal lesions other than OLP (non-OLP group), and subjects without oral mucosal lesions (control group). MATERIAL AND METHODS: Xerostomia as well as SFR was investigated in the three groups. Samples for isolation of Candida spp. were collected from OLP lesions (38 patients), non-OLP lesions (28 patients), and healthy subjects (32 subjects). RESULTS: There was no statistically significant difference regarding the frequency of xerostomia and hyposalivation among the three groups (P > 0.05). A higher prevalence for colonization by Candida spp. was found in the healthy subject as compared to that of patients with OLP (P = 0.03) and non-OLP (P = 0.02) groups. Low SFR was not a factor for colonization by Candida spp. CONCLUSIONS: Xerostomia and hyposalivation occur with similar frequency in subjects with and without oral lesions; also, the presence of oral lesions does not increase the susceptibility to colonization by Candida spp. It seems that any study implicating Candida spp. in the malignant transformation of oral lesions should be carried out mostly on a biochemical basis, that is, by testing the capability of Candida spp. to produce carcinogenic enzyme.Oral Diseases (2014) 20, e36-e41
