Is there an association between drugs and burning mouth syndrome? A case-control study

Oral lesions associated with imatinib mesylate therapy: five new cases and a literature review

This study aimed to report the collective clinical characteristics of oral side effects associated with imatinib therapy according to age, sex, and clinical condition. A bibliographic review was performed using the PubMed, Web of Science, Scopus, Cochrane Library, and Embase databases. Forty-five cases of oral side effects due to imatinib therapy were identified in the literature. With the addition of five new cases seen at the authors' institution, a total of 50 cases were analysed. Of the five new cases, four with gastrointestinal stromal tumours developed oral lichenoid lesions (OLLs), and one with chronic myeloid leukaemia (CML) developed oral hyperpigmentation (OHP). Of the total 50 patients, 26 were male and 24 were female, and age ranged from 29 to 86 years. Most patients were ≥50 years old (80%); only three patients were jaw was the least common, with just five cases (10%). Among the patients with OHP, the predominant clinical condition was CML (22 cases, 91.7%). In conclusion, the possibility of oral side effects needs to be considered during the examination of patients receiving imatinib therapy.

Prevalence of hypertension and correlation with mental health in women with burning mouth syndrome: A case-control study

Background

The relationship between hypertension (HTN) and chronic pain is still a matter of debate, and its prevalence in patients with burning mouth syndrome (BMS) has never been evaluated. This study aimed to assess the prevalence of HTN in women with BMS and to evaluate its relationship with potential predictors such as risk factors for cardiovascular diseases, pain, and mental health status analyzing differences with healthy women.

Methods

In total, 250 women with BMS (WBMS) were prospectively recruited and compared with an equal number of healthy women (HW) matched for age. Education, body mass index, smoke and alcohol consumption, intensity and quality of pain, and psychological profile were further investigated to identify the potential predictors of HTN. Specifically, pain assessment [the Numeric Rating Scale (NRS) and Short-Form McGill Pain Questionnaire (SF-MPQ)] and psychological assessment [Hamilton Rating Scale for Depression and Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS)] was carried out for the participants.

Results

HTN was found in 128 (51.2%) WBMS and 76 (30.4%) HW (p < 0.001^**). The scores of the NRS, SF-MPQ, HAM-D, HAM-A, and PSQI were statistically significantly higher in the WBMS than in the HW (p < 0.001^**). A strongly linear correlation between HTN and employment status, systemic diseases, and education level (p < 0.001^**) was found in WBMS, while a strong correlation between HTN and employment status, hypercholesterolemia, systemic diseases, and drug consumption was found in HW (p < 0.001^**). No statistically significant correlation was found between HTN and pain, anxiety, depression, and sleep disturbances.

Conclusion

These results suggest that WBMS showed a higher prevalence of HTN compared with controls. Unemployed WBMS with lower education and other systemic comorbidities are at an increased risk of developing HTN. HTN is associated with alteration in the vascular structure and function of the brain, and these processes accelerate brain aging, which contributes to a reduction in intracortical connectivity, thus affecting the modulatory system of control of pain in patients with BMS, independently of their mental health assessment. Predictors that may underlie this association remain unclear, taking into account the differences found in HW, and should be further elucidated.

Association of medications with burning mouth syndrome in Taiwanese aged patients

Background/purpose

Burning mouth syndrome (BMS) occurs more frequently in middle-aged or elderly patients, especially the older female patients. It may relate to multiple medications in the older people. This study aimed to evaluate the association of polypharmacy with BMS.

Materials and methods

Eighty BMS patients aged from 45 to 80 years were recruited into this study, and their medical data, especially the medication records, were collected and analyzed to assess the association of polypharmacy with BMS.

Results

Of the 80 BMS patients, 14 did not take any medication, 38 took 1-4 medicines, 17 took 5-8 medicines, and 11 took ≥9 medicines. The mean number of medicines taken by each BMS patient is 4.49. For the 80 BMS patients, the mean number of medicines taken by each BMS patient was significantly higher in the older age group (7.00 ± 7.76; age ≥65 years; n = 31) than in the relatively younger age group (2.90 ± 2.95; age 45-64 years; n = 49) (P = 0.001). The similar result was also observed in the female BMS patients. We also found that psychotropics, gastroprotectors and gastrointestinal tract (GI)-associated drugs, and antihypertensives were the three most commonly used drugs in our 80 BMS patients. Among them, the relatively high frequencies of using anxiolytics and antidepressants in the psychotropics, and beta-blockers in the antihypertensives were observed.

Conclusion

Our findings suggest that multiple medications (polypharmacy) may play an important role in the development of BMS, especially for the older female BMS patients.

Smell, taste and trigeminal disorders in a 65-year-old population

BACKGROUND

Smell, taste and trigeminal disorders likely have a substantial impact on human daily life. However, data regarding the prevalence of these disorders in Norway are scarce. The aim of this study was to investigate the prevalence of smell, taste, trigeminal disorders and associated factors in a 65-year-old population in Oslo, Norway.

METHODS

A random sample of 223 individuals (123 men, 100 women) participated in the study. Medical history was obtained, and unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) were collected to determine salivary secretion rates. Sniffin`n Sticks and Taste Strips (Burghart Messtechnik GmbH, Wedel, Germany) were used for quantitative testing of olfactory and gustatory function. In addition, the participants' self-reported perceptions of smell and taste, and burning mouth sensation were investigated.

RESULTS

The results showed that 34 % of the participants had reduced smell (28 % hyposmia and 6 % anosmia) and 28 % had reduced taste perception (21 % hypogeusia and 7 % ageusia). 13 % of the partcipants had a combination of smell and taste disorders. Dysgeusia was reported by 5 % and burning mouth sensation (syndrome) by 3 % of the participants. Hyposmia, hypogeusia and ageusia were significantly more prevalent among men. Significant associations were found between taste disorders and previous history of cerebral hemorrhage and heart attack, and between burning mouth sensation and gastrointestinal disorders. Disturbances in olfactory, gustatory and trigeminal function were significantly related to medication use. Ageusia and burning mouth sensation were significantly more prevalent among smokers. Except from higher prevalence of ageusia among participants with hyposalivation with respect to SWS, no significant associations were found between salivary secretion rate and chemosensory or trigeminal disorders in the present study.

CONCLUSIONS

The present study revealed that one-third of 65-year-old individuals had impaired smell and more than one-fourth had impaired taste function. The prevalence of dysgeusia and burning mouth sensation was very low. Reduced smell and taste perception were more common among men than women. Furthermore, some diseases and medications were associated with chemosensory and trigeminal disorders. Ageusia was associated with SWS hyposalivation.

Burning Mouth Syndrome Induced by Angiotensin-Converting Enzyme Inhibitors

Burning mouth syndrome (BMS) is characterized as the sensation of burning in the tongue or any other area of the oral mucosa without a medical or dental cause. BMS's pathophysiology is poorly understood and may be caused by its association with various factors, particularly with antihypertensive or psychotropic medicines. Although BMS is a relatively common intraoral disorder in the dental field, emergency physicians rarely recognize it. We report a 53-year-old Japanese woman who presented to our ED with a three-week history of a strange taste and burning tongue. The patient had poor control of hypertension, captopril, an angiotensin-converting enzyme (ACE) inhibitor, was added three weeks before presentation. We discontinued her ACE inhibitor and changed her medication to a beta-blocker. After two weeks, her symptoms improved. Emergency physicians must be aware that ACE inhibitors play some roles in the pathogenesis of BMS. The correct diagnosis of the condition depends on recognizing the disease and improving the quality of life.

General health status of a sample of patients with burning mouth syndrome: A case-control study

BACKGROUND

The relationship of burning mouth syndrome (BMS) with possible alterations in patients' general health has been subject of study and controversy during the last years.

OBJECTIVE

To analyse the general health status of patients with BMS, comparing it with a control group.

METHODS

A case-control study was conducted to compare the diseases, medications, blood test alterations, disturbances in general health, oral quality of life, xerostomia, sleep quality and psychological status between a group of 20 patients with BMS and a group of 40 patients who did not suffer from this disease.

RESULTS

BMS patients suffered more comorbidities and consumed more medications than controls. More mental, behavioural or neurodevelopmental disorders in BMS patients were found, consuming more drugs for nervous and cardiovascular systems, and alimentary tract and metabolism. Lower levels of iron and higher levels of folic acid were found in BMS patients compared to controls. General health status, oral health impact, sleepiness, psychological status and xerostomia levels were also significantly worsened in BMS patients than in controls.

CONCLUSIONS

BMS patients presented a worsened health status over controls suffering more comorbidities, consuming more medications and showing adverse results in all the health variables analysed in this study.
