Abstract
The aim of this systematic review and network meta-analysis (NMA) of randomized controlled trials was to evaluate the effectiveness of treatments for pain relief of burning mouth syndrome (BMS). Five databases and gray literature were searched. Independent reviewers selected studies, extracted data, and assessed the risk of bias. The primary outcome was pain relief or burning sensation, and the secondary outcomes were side effects, quality of life, salivary flow, and TNF-α and interleukin 6 levels. Four comparable interventions were grouped into different network geometries to ensure the transitivity assumption for pain: photobiomodulation therapy, alpha-lipoic acid, phytotherapics, and anxiolytics/antidepressants. Mean difference (MD) and 95% CI were calculated for continuous outcomes. The minimal important difference to consider a therapy beneficial against placebo was an MD of at least -1 for relief of pain. To interpret the results, the GRADE approach for NMA was used with a minimally contextualized framework and the magnitude of the effect. Forty-four trials were included (24 in the NMA). The anxiolytic (clonazepam) probably reduces the pain of BMS when compared with placebo (MD, -1.88; 95% CI, -2.61 to -1.16; moderate certainty). Photobiomodulation therapy (MD, -1.90; 95% CI, -3.58 to -0.21) and pregabalin (MD, -2.40; 95% CI, -3.49 to -1.32) achieved the minimal important difference of a beneficial effect with low or very low certainty. Among all tested treatments, only clonazepam is likely to reduce the pain of BMS when compared with placebo. The majority of the other treatments had low and very low certainty, mainly due to imprecision, indirectness, and intransitivity. More randomized controlled trials comparing treatments against placebo are encouraged to confirm the evidence and test possible alternative treatments (PROSPERO CRD42021255039).

Abstract
This study was conducted to assess the psychological characteristics of, and determine the effectiveness of group cognitive-behavioral (CB) treatment for, patients with burning mouth syndrome (BMS). The baseline characteristics of 24 female patients (age 69.7 ± 5.9 years) and an identical number of healthy female control subjects (age 69.2 ± 5.5 years) were compared. The patient group had significantly higher anxiety scores (P < 0.05) at baseline. A brief group CB intervention was delivered in a small-group format. Two sessions were planned 6 months apart. A numeric rating scale (NRS) was used to assess pain intensity. Anxiety was evaluated using a state and trait anxiety inventories. Present pain intensity decreased after both the first and second sessions. The session effect was significant (P = 0.02), but no repeat effect was found (P = 0.19). The state anxiety inventory score also decreased after the second session. The session effect was significant (P < 0.01), as was the repeat effect (P < 0.01). The trait anxiety inventory score decreased after the second session, and the session effect was significant (P = 0.013), but the repeat effect was not (P = 0.93). The results suggest that a brief group CB intervention reduces pain intensity and anxiety in patients with BMS.

Abstract
IMPORTANCE OF THE FIELD Capsaicin and its receptor, TRPV1, occupy a central place in current neurophysiological studies regarding pain transmission and have opened new avenues for understanding the role of transient receptor potential (TRP) receptors in itch processing. Substantial efforts in drug discovery are at present directed at vanilloid receptors for finding new remedies for pain and itch. AREAS COVERED IN THIS REVIEW We provide an overview of the major clinical indications of capsaicin, primarily targeting pain and itch of various origins, with an emphasis on the usefulness of capsaicin in treating pruritus and dermatological conditions. In particular, we cover the most relevant findings in recent years, from 2000 onward (although seminal discoveries and studies are discussed irrespective of their date of publication if deemed essential for understanding capsaicin's actions). WHAT THE READER WILL GAIN Readers are offered a broad perspective on the areas of clinical application of capsaicin, emphasizing its usefulness in the treatment of neurophatic pain and pruritus of various origins. TAKE HOME MESSAGE Capsaicin has been proven a truly exciting molecule and remains a valuable drug for alleviating pain and itch, widely surpassing its role as a simple spicy ingredient.

Abstract
BACKGROUND Cutaneous dysaesthesia syndromes are characterized by chronic cutaneous symptoms without objective findings, and their aetiologies are obscure. Trichodynia describes pain and a stinging sensation of the scalp related to diffuse alopecia. AIMS To determine the prevalence rate of trichodynia in patients with diffuse alopecia; to assess the serum zinc, folate and vitamin B(12) levels; and to investigate the significance of psychological disorders in these patients. METHODS The study comprised 91 patients with a diagnosis of diffuse hair loss and 74 healthy controls. Patients were questioned about the presence of trichodynia, and their serum zinc, folate and vitamin B(12) levels were assessed. They were also evaluated using the Beck Depression Inventory (BDI), the Beck Anxiety Inventory, and the Somatoform Dissociation Questionnaire (SDQ). RESULTS The rates of androgenetic alopecia and telogen effluvium were 26.4% and 73.6%, respectively, Trichodynia was found in 30 patients (33%), and was more common in the telogen effluvium group than in the androgenetic alopecia group (P = 0.5). There was no significant difference between the patients with alopecia and controls for zinc, folate and vitamin B(12) levels, or for psychological test scores. However, the BDI and SDQ scores were significantly higher (P = 0.03 and P = 0.01, respectively) in patients with than those in without trichodynia. CONCLUSIONS Trichodynia is a commonly encountered symptom in patients with diffuse alopecia, and depression and somatoform dissociation disorders may play an important role in its aetiology. Our data provide no evidence that serum levels of zinc, folate or vitamin B(12) are involved in the pathogenesis of trichodynia.

Abstract
Two case reports of patients suffering from burning mouth syndrome (BMS), a type of somatoform disorder, who were treated with olanzapine are discussed. One case was a 54-year-old female with BMS who failed to respond to milnacipran treatment. Olanzapine (2.5 mg/day) brought about dramatic improvement in the patient's symptoms, and thereafter milnacipran withdrawal further eliminated her symptoms. The second case was a 51-year-old male with BMS who failed to respond to paroxetine treatment. Olanzapine (2.5 mg/day) was added to the treatment regimen and increased to 5.0 mg/day the following week. The patient noted a reduction in symptoms and continued to live normally thereafter without experiencing severe symptoms. These findings suggest that olanzapine may be useful in the treatment of BMS.

Abstract
The mucosal immune system in the upper female reproductive tract is uniquely prepared to maintain a balance between the presence of commensal bacteria, sexually transmitted bacterial and viral pathogens, allogeneic spermatozoa, and an immunologically distinct fetus. At the center of this dynamic system are the epithelial cells that line the Fallopian tubes, uterus, cervix and vagina. Epithelial cells provide a first line of defense that confers continuous protection, by providing a physical barrier as well as secretions containing bactericidal and virucidal agents. In addition to maintaining a state of ongoing protection, these cells have evolved to respond to pathogens, in part through Toll-like receptors (TLRs), to enhance innate immune protection and, when necessary, to contribute to the initiation of an adaptive immune response. Against this backdrop, epithelial cell innate and adaptive immune function is modulated to meet the constraints of procreation. The overall goal of this review is to focus on the dynamic role of epithelial cells in the upper reproductive tract, with special emphasis on the uterus, to define the unique properties of these cells as they maintain homeostasis in preparation for successful fertilization and pregnancy while at the same time confer protection against sexually transmitted infections, which threaten to compromise women's reproductive health and survival. By understanding the nature of this protection and the ways in which innate and adaptive immunity are regulated by sex hormones, these studies provide the opportunity to contribute to the foundation of information essential for ensuring reproductive health.

Abstract
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.

Abstract
OBJECTIVE Burning mouth syndrome (BMS) has been attributed secondarily to diabetes, poor glycemic control, and diabetic neuropathy. The prevalence and predictor factors of BMS were compared in type 1 diabetes mellitus (T1DM) and nondiabetic subjects. STUDY DESIGN An assessment of 371 adult T1DM subjects and 261 control subjects participating in a cross-sectional epidemiological study of oral health complications of diabetes was performed. Subjects were participants of the Pittsburgh Epidemiology of Diabetes Complications study. Prevalence of BMS was determined by response to the following questions: "Do you now or in the last month had any persistent uncomfortable sensations in your mouth or tongue? If yes, would you describe the feeling as tingling, burning, sore, numb, or other?" RESULTS Burning mouth syndrome symptoms were reported by 28 T1DM and control subjects (4.6%). Eleven had oral pathologies that might explain the BMS, including atrophy of the tongue papillae, fissured tongue, denture stomatitis, and candidiasis. The prevalence of BMS within the two groups with no pathologies was similar; 12/371 (3.2%) vs. 5/233 (2.1%). Multivariate analyses of the 12 T1DM subjects with BMS found significant associations for female gender (P=.042) and a diagnosis of diabetic peripheral neuropathy (P=.024). CONCLUSIONS In this T1DM population, BMS or related discomforts occurred slightly more frequently than in the control group. Symptomatic T1DM subjects were more likely to be female who had also developed peripheral neuropathy. These findings and other similarities between BMS and diabetic peripheral neuropathy suggest that a neuropathic process may be an underlying source of BMS in some patients who have no apparent oral abnormality.

Abstract
"Nihilodermia" refers to a group of difficult "problem" patients in dermatology without objective findings but with recurrent symptoms and stubborn demand for medical examination. These primary emotional disorders are somatoform disorders, but the patients usually strictly deny a psychosocial aspect and expect purely somatic treatment. Clinical patterns include pruritus, pain, paresthesias, feelings of disfiguration, eco-syndromes, erythrophobia and psychogenic pseudoeffluvium. The relevant somatoform disorders in dermatology can be differentiated as somatization disorders, hypochondriacal disorders, somatoform autonomous disorders, persistent somatoform pain disorders and "other somatoform disorders". A precise differential diagnostic division is necessary in order to initiate adequate therapy strategies.

Abstract
"Burning mouth syndrome" (BMS) refers to a chronic orofacial pain disorder usually unaccompanied by mucosal lesions or other clinical signs of organic disease. BMS is typically characterized by a continuous, spontaneous, and often intense burning sensation as if the mouth or tongue were scalded or on fire. Burning mouth syndrome is a relatively common condition. The estimated prevalence of BMS reported in recent studies ranges between 0.7 and 4.6% of the general population. About 1.3 million American adults, mostly women in the postmenopausal period, are afflicted with BMS. The etiology of this disorder is poorly understood even though new evidence for a possible neuropathic pathogenesis of idiopathic BMS is emerging. Burning mouth syndrome may present as an idiopathic condition (primary BMS type) distinct from the symptom of oral burning that can potentially arise from various local or systemic abnormalities (secondary BMS type), including nutritional deficiencies, hormonal changes associated with menopause, local oral infections, denture-related lesions, xerostomia, hypersensitivity reactions, medications, and systemic diseases including diabetes mellitus. In more than a third of patients, multiple, concurrent causes of BMS may be identified. It is important to note that the diagnosis of BMS should be established only after all other possible causes have been ruled out. Professional delay in diagnosing, referring, and appropriately managing of BMS patients occurs frequently. Treatment should be tailored to each patient and it is recommended to practice the treatment in a multidisciplinary facility. This article discusses our current understanding of the etiology and pathogenesis of BMS. The authors have tried to emphasize new pharmacological approaches to manage this challenging disorder.

Abstract
This paper reviews a wide range of somatization-related symptoms that are encountered in dermatology. These include the unexplained cutaneous sensory syndromes especially the cutaneous dysesthesias associated with pain, numbness and pruritus; traumatic memories in post-traumatic stress disorder (PTSD) which are experienced on a sensory level as 'body memories' and may present as local or generalized pruritic states, urticaria and angioedema; and unexplained flushing reactions and profuse perspiration, in addition to unexplained exacerbations of stress-reactive dermatoses such as psoriasis and atopic eczema secondary to the autonomic hyperarousal in PTSD; classic 'pseudoneurologic' symptoms associated with dissociation including unexplained loss of touch or pain, in addition to the self-induced dermatoses such as dermatitis artefacta and trichotillomania that are encountered with dissociative states; and body dysmorphic disorder where the patient often presents with a somatic preoccupation involving the skin or hair.

Abstract
A 73-year-old white male with a 6-month history of glossodynia, unresponsive to clotrimazole troches, cevimeline, triamcinolone dental paste, paroxetine, and lorazepam presented to the dermatology clinic for consultation. Work-up revealed no oral abnormalities and no underlying systemic disorder. He denied symptoms consistent with a psychiatric disorder. A detailed free amnestic assessment by a board certified Geriatric Psychiatrist (John S. Kennedy, MD) found that the patient was oppressed by the pain. He did not meet the criteria for major depression nor did he have any anxiety disorder or delusions. Because of the presence of dysphoria and anticipatory anxiety secondary to glossodynia, the patient was started on olanzapine. Improvement of pain symptoms were noted within 3 days with full resolution of symptoms at 1- and 3-month follow-ups. Dysphoria and anticipatory anxiety remitted fully upon pain relief.

Abstract
OBJECTIVE We have examined the effect of alpha-lipoic acid (ALA, tioctic acid; Tiobec), a free radical scavenger, on the discomfort of burning mouth syndrome (BMS) in patients who had used tranquillizers previously, compared with those who had not. METHODS In this study we gave lipoic acid for 2 months to two groups of 20 BMS patients, one of which had previously been treated with tranquillizers. RESULTS The results showed greater effectiveness of lipoic acid in BMS patients who had not previously used tranquillizers. CONCLUSIONS The patients with BMS who had previously been treated with tranquillizers responded poorly to therapy with lipoic acid compared with those who had not received previous psychotropic therapy.

Abstract
Stomatodynia is characterised by a spontaneous burning pain in the oral mucosa without known cause or recognised treatment. The purpose of this double-blind, randomised, multicentre parallel group study was to evaluate the efficacy of the topical use of clonazepam. Forty-eight patients (4 men and 44 women, aged 65+/-2.1 years) were included, of whom 41 completed the study. The patients were instructed to suck a tablet of 1 mg of either clonazepam or placebo and hold their saliva near the pain sites in the mouth without swallowing for 3 min and then to spit. This protocol was repeated three times a day for 14 days. The intensity was evaluated by a 11-point numerical scale before the first administration and then after 14 days. Two weeks after the beginning of treatment, the decrease in pain scores was 2.4+/-0.6 and 0.6+/-0.4 in the clonazepam and placebo group, respectively (P = 0.014). Similar effects were obtained in an intent-to-treat analysis (P = 0.027). The blood concentration of clonazepam was similar whether it was measured 14 days after sucking a tablet three times a day or during the 5 h that followed sucking a single tablet (n = 5). It is hypothesised that clonazepam acts locally to disrupt the mechanism(s) underlying stomatodynia.

Burning Mouth Syndrome (BMS) is a chronic pain syndrome that mainly affects middle-aged/old women with hormonal changes or psychological disorders. This condition is probably of multifactorial origin, often idiopathic, and its etiopathogenesis remains largely enigmatic. The present paper discusses several aspects of BMS, updates current knowledge, and provides guidelines for patient management. There is no consensus on the diagnosis and classification of BMS. The etiopathogenesis seems to be complex and in a large number of patients probably involves interactions among local, systemic, and/or psychogenic factors. In the remaining cases, new interesting associations have recently emerged between BMS and either peripheral nerve damage or dopaminergic system disorders, emphasizing the neuropathic background in BMS. Based on these recent data, we have introduced the concepts of "primary" (idiopathic) and "secondary" (resulting from identified precipitating factors) BMS, since this allows for a more systematic approach to patient management. The latter starts with a differential diagnosis based on the exclusion of both other orofacial chronic pain conditions and painful oral diseases exhibiting muco-sal lesions. However, the occurrence of overlapping/overwhelming oral mucosal pathologies, such as infections, may cause difficulties in the diagnosis ("complicated BMS"). BMS treatment is still unsatisfactory, and there is no definitive cure. As a result, a multidisciplinary approach is required to bring the condition under better control. Importantly, BMS patients should be offered regular follow-up during the symptomatic periods and psychological support for alleviating the psychogenic component of the pain. More research is necessary to confirm the association between BMS and systemic disorders, as well as to investigate possible pathogenic mechanisms involving potential nerve damage. If this goal is to be achieved, a uniform definition of BMS and strict criteria for its classification are mandatory.

Abstract
Burning mouth syndrome is the occurrence of oral pain in a patient with a normal oral mucosal examination. It can be caused by both organic and psychologic or psychiatric factors, which can be broken down into local, systemic. psychologic or psychiatric, and idiopathic causes. The most frequently associated conditions are psychiatric (depression, anxiety, or cancerphobia); xerostomia; nutritional deficiency; allergic contact dermatitis; candidiasis; denture-related pain: and parafunctional behavior. Multiple different factors contributing to the oral pain are common, and a systematic approach to the evaluation is important. Identification of correctable causes of BMS should be emphasized and psychiatric causes should not be invoked without thorough evaluation of the patient. A directed history and careful oral examination must be completed to exclude local diseases and identify clues to potential causes. Assessment of medications, psychiatric history and background, and selected laboratory and patch tests may help identify the etiologies of these symptoms. Treatment should be tailored to each patient and may best be managed in a multidisciplinary approach with input from dermatologists, dentists, psychiatrists. otorhinolaryngologists, and primary care providers. A thoughtful and structured evaluation of the patient with BMS has been associated with improvement in about 70% of patients. The remaining patients may benefit from empiric therapy with a chronic pain protocol and continued supportive interactions.

Abstract
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.

Abstract
A 71-year-old edentulous man developed a severely painful red mouth at sites of contact with a new denture. Patch testing showed allergy to samples of the denture material and to 2-hydroxyethyl methacrylate. Patch testing to methyl methacrylate was negative. Prolonged boiling of the denture resulted in reversal of his symptoms and samples of this fully cured denture material produced negative patch tests. While allergy to acrylates is a rare cause of stomatitis, this possibility must be considered in patients presenting with oral symptoms. Material safety data sheets are unreliable in providing information regarding the type of acrylate present in the material. Hence, patch testing should be performed with a battery of acrylate allergens as well as with small samples of the denture material.

Abstract
OBJECTIVE To report the first published case of clonazepam-induced burning mouth syndrome (BMS). CASE SUMMARY A 52-year-old white woman presented to the clinic with burning mouth symptoms. The patient was previously maintained on alprazolam therapy for anxiety, but was switched to clonazepam because of increased anxiety and panic. Clonazepam significantly relieved her symptoms, but after four weeks of therapy, she reported a constant, mild, oral burning sensation. An oral examination was negative for mucosal abnormalities, and laboratory tests were unremarkable. The clonazepam dose was reduced, and the symptoms decreased, but remained intolerable. Clonazepam was discontinued, and the burning mouth symptoms completely resolved. Since no other medications relieved the anxiety and panic symptoms, the patient requested clonazepam to be reinitiated, but she again developed intolerable burning mouth symptoms. As clonazepam was discontinued, the symptoms resolved. DISCUSSION The clinical presentation of BMS includes burning and painful sensations of the mouth in the absence of mucosal abnormalities. Candidiasis, anemia, menopause, diabetes mellitus, medications, anxiety, and depression are some causes of this syndrome. Paradoxically, clonazepam has been studied for the treatment of BMS and has demonstrated mild to moderate improvement. In this patient, underlying causes of BMS were eliminated when possible. The association between clonazepam and BMS was highly probable according to the Naranjo probability scale. CONCLUSIONS This is the first published report describing BMS with a benzodiazepine. Although uncommon, clinicians should be aware of this potential adverse effect due to the widespread use of benzodiazepines.

Abstract
The pathophysiology of burning mouth syndrome (BMS) is largely unknown. Thus, the aim was to study oral mucosal blood flow in BMS-patients using laser Doppler flowmetry (LDF). Thirteen BMS patients (11 female, two male; mean age+/-SD 64.3+/-7.9 years, mean disease duration 18.9+/-6.2 months) and 13 healthy non-smoking controls matched for age and gender (11 female, two male; mean age 64.7+/-8.1 years) were investigated. Using the LDF technique mucosal blood flow (mBF) was measured at the hard palate, the tip of the tongue, on the midline of the oral vestibule, and on the lip. Measurements were made at rest and over 2 min following dry ice application of 10 s duration using a pencil shaped apparatus. In addition, blood pressure (BP), heart rate (HR), peripheral cutaneous blood flow, and transcutaneous pCO(2) were continuously recorded. Mucosal blood flow (mBF) increased at all measurement sites in response to dry ice application (P<0.001) with peak flow at 0.5--1.5 min after stimulation onset. During the following 1.5--2 min, blood flow decreased at all sites with a tendency to return to baseline towards the end of the observation period. Except for BP and peripheral blood flow, all of the cardiovascular changes exhibited significant changes during the observation period; no differences between groups were detected. When compared to healthy controls BMS patients generally exhibited larger changes in mBF. These changes were significant for recordings made on the hard palate (F[1,24]=13.9, P<0.001). Dry ice stimulation appears to be an effective, non-invasive and reasonably tolerable means to investigate mucosal blood flow at different mucosal sites. In general, vasoreactivity in BMS patients was higher than in healthy controls. BMS patients exhibited a higher response on the hard palate compared to controls. These changes in oral blood flow appear to be specifically related to BMS symptoms indicating a disturbed vasoreactivity.

Abstract
Despite the progress that has occurred in recent years in the development of therapy, there is still a need for effective and potent analgesics, especially for the treatment of chronic pain. One of the most important analgesic drugs employed in clinical practice today continues to be the alkaloid morphine. In this review, emphasis will be given to the important contribution and the history of Papaver somniferum, Salix species, Capsicum species and Cannabis sativa in the development of new analgesics and their importance in the understanding of the complex pathways related to electrophysiological and molecular mechanisms associated with pain transmission. Recently discovered antinociceptive substances include alkaloids, terpenoids and flavonoid. Plant-derived substances have, and will certainly continue to have, a relevant place in the process of drug discovery, particularly in the development of new analgesic drugs.

Abstract
Allergic contact dermatitis (ACD) in dentistry may affect dentists and orthodontists, technicians, nurses and patients. Changes to dental practice in recent years have altered the reported frequencies of allergens causing ACD in both dental personnel and patients. Allergic contact dermatitis to medicaments, metals and glutaraldehyde were previously common allergens in dentistry; however, widespread adoption of rubber gloves by staff has resulted in a significant increase in ACD to glove allergens in both dental staff and their patients, while affording protection against the traditional allergens. Both public concerns about potential toxicity of metals in oral restorations and a greater demand for cosmetic dentistry, have resulted in greater use of acrylics and resins by dental personnel, exposing them to highly allergenic materials. Dermatologists need to be aware of the newer allergenic materials used in dentistry in order to correctly manage skin diseases in this high-risk group.

Abstract
OBJECTIVE The purpose of this study was to evaluate the efficacy of the topical use of benzydamine hydrochloride 0.15% oral mouthwashes in the control of burning mouth syndrome symptoms. STUDY DESIGN In this double-blind, randomized, longitudinal investigation, each of 30 patients with burning mouth syndrome was assigned to one of 3 management modalities. Those in group A received an oral rinse solution of benzydamine hydrochloride 0.15% 3 times a day for 4 weeks, those in group B received a placebo 3 times a day for 4 weeks, and those in group C did not receive any kind of treatment. A visual analog scale was used for evaluation of the symptoms; a Kruskal-Wallis analysis of variance exact test was performed on the resulting data. RESULTS The findings of this investigation failed to reveal significant differences among the groups. CONCLUSIONS The clinical application of benzydamine hydrochloride oral rinses in the treatment of patients with burning mouth syndrome did not demonstrate significative efficacy in comparison with use of a placebo solution.

Abstract
OBJECTIVE To review a series of patients with a burning or sore mouth for elucidation of associated conditions and treatment outcome. MATERIAL AND METHODS We retrospectively studied 70 consecutive patients with a burning or sore mouth who were encountered at a tertiary-care center between 1979 and 1992. Clinical and laboratory findings were summarized, and follow-up data were analyzed. RESULTS The study cohort of 56 women and 14 men had a mean age of 59 years. They had had a burning or sore mouth for a mean duration of 2.5 years. Multiple etiologic factors for the burning or sore mouth were present in 37% of the study subjects. The most frequently associated conditions were psychiatric disease (30%), xerostomia (24%), geographic tongue (24%), nutritional deficiencies (21%), and allergic contact stomatitis (13%). With a treatment course tailored to the suspected causal factor, 72% of the patients who had follow-up reported improvement. CONCLUSION With a directed investigation, one or more causes could be identified in most patients who had a burning or sore mouth. Successful management of these symptoms was possible in a majority of the patients.

Abstract
OBJECTIVE The purpose of this study was to evaluate the usefulness of a Kampo medicine (Sai-boku-to) for treatment of patients with glossodynia. STUDY DESIGN Sai-boku-to or an antianxiety drug (diazepam) with vitamin B complex was administered orally for 3 months to each of 200 patients with glossodynia. Clinical examination evaluated the following subjective symptoms: pain, burning sensation, and discomfort. Effectiveness was evaluated as follows: "markedly effective," all 3 symptoms disappeared; "effective," pain improved; "ineffective," no improvement in pain. RESULTS The effective rates were 70% after 1 month, 85% after 2 months, and 92% after 3 months of administration of Sai-boku-to (the Kampo group) and 74% after 1 month, 71% after 2 months, and 69% after 3 months of administration of the antianxiety drug with vitamin B complex (the control group). No significant side effect was noted in the Kampo group, but sleepiness was recorded in 33 cases in the control group. CONCLUSIONS The results indicate that Sai-boku-to may be a clinically useful medicine for the long-term treatment of patients with glossodynia.

Abstract
OBJECTIVE Current treatment for burning mouth syndrome is usually directed at correction of detected organic causes or is empiric, and it often involves the use of tricyclic antidepressants. Recently, there has been renewed interest in the use of benzodiazepines for burning mouth syndrome. The present study was designed to assess the effect of clonazepam in burning mouth syndrome. STUDY DESIGN Thirty patients, each with a chief complaint of mouth burning without oral mucosal lesions, were entered into the study. All patients underwent routine blood screens. Identified abnormalities were corrected, when possible, before clonazepam was prescribed. The starting dose was 0.25 mg daily, with an increase in dose of 0.25 mg on a weekly basis if symptoms continued. RESULTS The subject population consisted of 29 women and 1 man. All subjects had been symptomatic (average premorbid burning intensity, 7.0 +/- 1.9 on 10-point scale) for 1 month to 12 years (mean, 3.9 +/- 3.4 years; median, 2.75 years), and 16% had had burning for more than 2 years. Three groups of patients were identified: those who experienced partial to complete relief with clonazepam and who were using the medication at the last follow-up (group 1; 43%); those who found the clonazepam helpful but withdrew from the medication because of side effects--usually drowsiness (group 2; 27%); and those who did not benefit from clonazepam (group 3; 30%). Among the 3 groups, age was found to be significantly lower for group 1 than for group 2 but not significantly lower for group 1 than for group 3. Although the difference did not reach significance, the mean dose of clonazepam appeared lower for group 1 patients than for the other 2 patient groups. The number of patients with burning for less than 2 years was larger in group 1 than in the other groups. CONCLUSIONS The results suggest that clonazepam may be helpful in burning mouth syndrome, inasmuch as 70% of patients (groups 1 and 2) experienced pain reduction with effects at low doses. These findings suggest that the mechanism of action of clonazepam may be specific and separate from the anxiolytic effect of the benzodiazepines and that clonazepam may represent a useful therapy in a subset of patients with burning mouth syndrome. Double-blind, placebo-controlled trials are warranted.

Abstract
Contact stomatitis is rather uncommon because of the relative resistance of the oral mucosa to irritant agents and allergens. The clinical manifestations of contact stomatitis are extremely variable and include erythema, erosions, ulcerations, leukoplakia-like lesions, and lichenoid reactions. Clinical signs are frequently less pronounced than subjective symptoms, and patients commonly experience severe functional problems despite only mild mucosal alterations. Allergic stomatitis is rare and almost always attributable to metallic mercury and gold salts. A careful history and an accurate examination of the oral cavity, teeth, and dental restorations are essential for a correct diagnosis. Patch testing is indicated in all lesions that are not clearly related to trauma or physical injuries. Patch testing is not useful in the burning mouth syndrome. Evaluation of clinical relevance of patch test results is always very difficult and requires an interdisciplinary approach to the patient. Successful treatment requires the identification and elimination of the causative factor, when possible. It is important to bear in mind that replacement of dental restorations and prostheses may be very expensive and stressful for the patient and thus should not be recommended when their causative role is doubtful.
