Courtesy stigma of parents of children with Down syndrome: Adaptation process and transcendent stage.

Courtesy stigma, which arises from close connections to people with stigmatized characteristics, negatively affects interpersonal relations. This study aimed to evaluate courtesy stigma and the adaptation process of parents of children with Down syndrome based on semi-structured interviews with 23 Japanese parents. The interview themes were (a) negatively perceived interpersonal experiences and coping strategies; (b) information disclosure and others' responses; and (c) positively perceived interpersonal experiences. The interview data were transcribed and analyzed based on a grounded theory approach. The results suggested that parents perceived and experienced multidimensional courtesy stigma, and they used various coping strategies categorized in combinations of passive-active and internal-external. All parents disclosed information about their child's diagnosis to others, and reverse disclosure (i.e., revealing own relations with people with disabilities) was characteristically observed thereafter. Through active interaction and reflection, the parents cultivated social relationships, compassion, world views, and community involvement, which led to the transcendent stage. However, internal conflict as a mediator between people with and without Down syndrome re-emerged even after achieving the transcendent stage. These findings could help to develop interventions in genetic counseling for parents to deal with interpersonal relationship difficulties.

Comorbid depressive disorders and left-side dominant occlusal discomfort in patients with phantom bite syndrome.

BACKGROUND: Phantom bite syndrome (PBS) is characterised by occlusal discomfort without corresponding dental abnormalities. Despite repeated, failed dental treatments, patients with PBS persist in seeking bite correction. PBS has been regarded as a mental disorder. However, we have reported that PBS patients with a dental trigger tend to have less psychiatric history than those without. Hence, the symptoms of PBS cannot be explained by a mental disorder alone, and it is unclear if mental disorders affect occlusal sensation. OBJECTIVE: To elucidate the pathophysiology of PBS, we analysed the dental history, PBS symptom laterality and psychiatric history of patients. METHODS: In this retrospective study, we reviewed outpatients with PBS who presented at our clinic between April 2012 and March 2017. Their medical records were reviewed for demographic data, medical history and laterality of occlusal discomfort. RESULTS: Approximately half of the 199 enrolled patients had bilateral occlusal discomfort. In the others, the side with occlusal discomfort generally tended to be the one that had received dental treatment. There was no significant relationship between the side chiefly affected by occlusal discomfort and whether dental treatment had been received; however, the affected side differed depending on whether the patient had comorbid psychiatric disorders (P = .041). CONCLUSIONS: The distributions of the side with symptoms of PBS were different between those with and without comorbid psychiatric disorders, suggesting that psychiatric disorders might affect occlusal sensation due to a subtle dysfunction in brain areas central to sensory integration. Central dysfunction might play an important role in PBS.

Evaluating Burning Mouth Syndrome as a Comorbidity of Atypical Odontalgia: The Impact on Pain Experiences.

OBJECTIVE: This study aimed (1) to investigate the differences in clinical characteristics of patients between 2 groups, those who have atypical odontalgia (AO) only and those who have AO with burning mouth syndrome (BMS), and (2) to assess the influence of psychiatric comorbidity factors on patients' experiences. METHOD: Medical records and psychiatric referral forms of patients visiting the Psychosomatic Dentistry Clinic of Tokyo Medical and Dental University between 2013 and 2016 were reviewed. The final sample included 2 groups of 355 patients: those who have AO only (n = 272) and those who have AO with BMS (AO-BMS; n = 83). Clinicodemographic variables (gender, age, comorbid psychiatric disorders, and history of headache or sleep disturbances) and pain variables (duration of illness, pain intensity, and severity of accompanying depression) were collected. Initial pain assessment was done using the Short-Form McGill Pain Questionnaire, and depressive state was determined using the Zung Self-Rating Depression Scale. RESULTS: The average age, female ratio, and sleep disturbance prevalence in the AO-only group were significantly lower than those in AO-BMS group. AO-BMS patients rated overall pain score and present pain intensity significantly higher than did the AO-only patients (P = 0.033 and P = 0.034, respectively), emphasizing sharp (P = 0.049), hot-burning (P = 0.000), and splitting (P = 0.003) characteristics of pain. Patients having comorbid psychiatric disorders had a higher proportion of sleep disturbance in both groups and a higher proportion of depressive state in the AO-only group. CONCLUSIONS: AO-BMS patients have different epidemiological characteristics, sleep quality, and pain experiences compared to AO-only patients. The presence of psychiatric comorbidities in both groups may exacerbate sleep quality. We suggest that BMS as a comorbid oral disorder in AO patients contributes to a more intensively painful experience.

Atypical MRI and Histopathological Findings in Dermoid Cyst.

On images, a dermoid cyst is often described as resembling a "sack of marbles" or "marbles in a bag". Typically, it comprises an inhomogeneity filled with multiple nodules in a fluid matrix on both computed tomography and magnetic resonance imaging (MRI). How it appears, however, will vary depending on its histological contents, which may cause confusion in arriving at a diagnosis. This report describes a dermoid cyst in the floor of the mouth of a 55 year-old woman that showed an atypical internal appearance on MRI. Most of the lesion showed homogeneous high signal intensity on T1 - and T2-weighted images, suggesting that it was derived from fat. A small area within the mass, however, showed moderate signal intensity almost equal to that of muscle on T1-weighted images and high signal intensity on fat-suppressed T2-weighted images. Given the location of the lesion, a dermoid cyst was one possible diagnosis. A lipoma or lipoma variants were also considered, however, based on signal intensity. Histopathological section of the excised specimen revealed a dermoid cyst with sebaceous glands in its walls and keratin in its cavity. Dermoid cysts show variation in their internal structures and contents. Since MRI can reflect such histological variation, signal intensity requires careful interpretation.

Genetic Counseling for Couples Seeking Noninvasive Prenatal Testing in Japan: Experiences of Pregnant Women and their Partners.

The recent advent of noninvasive prenatal testing (NIPT) has had a significant impact in the field of prenatal testing. Although reports on pregnant women who used NIPT have accumulated, little is known about the experiences of their male partners. In this study, we assessed the experiences of couples who were expecting a child and undergoing NIPT, with a focus on both the pregnant women and their partners. Questionnaires were administered to 282 participants focusing on their specific experiences at three time points: after pre-test counseling (first visit), when undergoing NIPT (second visit), and when results were received (third visit). Responses were analyzed to assess the differences between pregnant women and their partners. We found that more partners selected "family" as their first information source about NIPT and "my partner" as the first person to request NIPT than did pregnant women (35.6 vs. 5.9 %; p < 0.001 and 19.3 vs.1.5 %; p < 0.001). However, pregnant women more often consulted others including family and friends until undergoing NIPT than their partners (89.1 vs. 54.6 %; p < 0.001). Our findings suggest that it is important to encourage male partners to be actively involved in the NIPT decision-making process. Differences between pregnant women and their partners should be seriously considered when providing genetic counseling.

Comparison of cerebral blood flow in oral somatic delusion in patients with and without a history of depression: a comparative case series.

BACKGROUND: A significant number of patients visit dental clinics because of unusual oral sensations for which no physical cause can be found. Such patients are recognized as having oral somatic delusion (OSD). OSD may be either primary (monosymptomatic) or secondary to another disease, such as depression or cerebral infarction. Although the presenting complaints of patients with primary and secondary OSD are nearly indistinguishable, symptoms in patients with secondary OSD seem to be resistant to treatment compared with those in patients with primary OSD. Moreover, right dominant cerebral blood flow (CBF) has been reported in patients with primary OSD, but the difference in CBF between patients with primary and secondary OSD remains unclear. The aim of this study was to assess the differences in clinical characteristics and CBF distribution between patients with monosymptomatic OSD (non-depression group) and OSD in conjunction with remitted depression (depression group). METHODS: Participants were 27 patients of a psychosomatic dentistry clinic, all diagnosed with OSD. They were categorized into either the non-depression group (17 patients) or the depression group (10 patients) on the basis of assessments by their personal medical providers. CBF was examined using single-photon emission computed tomography. RESULTS: There was no difference in clinical presentation between the two groups. A significant right dominant asymmetry in the temporal and posterior cerebral regions was observed in both groups. In the central region, a right dominance was seen in the non-depression group, while a left dominance was seen in the depression group. Moreover, the mean regional CBF values for patients in the depression group were significantly lower in several regions (including bilateral callosomarginal, precentral, angular, temporal, posterior cerebral, pericallosal, lenticular nucleus, thalamus, and hippocampus; and right central and cerebellum) than for patients in the non-depression group. CONCLUSION: These results suggest that the temporal and posterior cerebral regions are involved in in the pathophysiology of OSD, regardless of depression history, and that widespread CBF reduction is a characteristic of remitted depression.

Oral Dysesthesia Rating Scale: a tool for assessing psychosomatic symptoms in oral regions.

BACKGROUND: The concept of cenesthopathy was first introduced by Dupré and Camus in 1907 to describe clinically unexplainable bodily sensations mainly attributed to psychiatric pathology. If it occurs in oral regions, it is termed oral cenesthopathy and it has been of special interest to psychiatrists and dentists. While there is no independently defined criteria for this condition, which is classified as either a delusional or a somatoform disorder, clinical practice and research require a standard scale to measure and rate its symptoms. In this study, we included any types of psychosomatic symptoms in oral regions as oral dysesthesia, and developed an Oral Dysesthesia Rating Scale (Oral DRS) and evaluated its validity and reliability as an assessment tool. METHODS: The scale was developed based on literature review and extensive clinical experience. Twelve reviewers assessed relevancy of each item to oral dysesthesia symptoms by 1-4 scoring scale and item content validity index was computed. To evaluate the inter-rater reliability of Oral DRS, pairs of raters administered the scale to 40 randomly selected patients with complaints of oral dysesthesia symptoms and Cohen's weighted kappa coefficient was determined for each item. RESULTS: The scale assesses the severity of feelings of foreign body [A1], exudation [A2], squeezing-pulling [A3], movement [A4], misalignment [A5], pain [A6], and spontaneous thermal sensation or tastes [A7], and the degree of impairment in eating [B1], articulation [B2], work [B3], and social activities [B4] on a scale of 0-5. Items A1, A2, A3, A4, B3, and B4 demonstrated acceptable content validity. Inter-rater reliabilities were good or excellent for all items evaluated. CONCLUSION: The Oral DRS can help define the nosography of clinically unexplainable oral dysesthesia through further case evaluation and clinical research and facilitate devising of treatment modalities.

Goal Attainment Scaling in Patients With Burning Mouth Syndrome: A Real-World Clinical Study Protocol.

Introduction Burning mouth syndrome (BMS) is characterized by persistent chronic burning pain. Because BMS shows various symptoms, levels of severity, and treatment outcomes, measuring recovery is difficult in this patient population. Goal attainment scaling (GAS), a flexible and responsive technique for assessing outcomes in complex interventions, assimilates the achievement of individual goals into a single standardized "goal attainment scale." To our knowledge, this is the first clinical study protocol to investigate the effectiveness of adopting GAS in patients with BMS. Methods This study will involve two phases. In phase 1, the suitability of GAS for BMS will be examined in 30 patients. All practitioners will be trained to support patients in setting their clinical goals. In phase 2, all 155 patients with BMS will set two clinical goals emphasizing specific, measurable, achievable, realistic, and timed (SMART) goals at the initiation of psychopharmacotherapy for BMS. During the follow-up at weeks four, 8, 12, and 24, the GAS T-scores for each patient will be derived from the result of the individual goal attainment scores multiplied by goal weighting. Other clinical rating scales, including the visual analog scale (VAS), oral dysesthesia rating scale, pain catastrophizing scale, patient's global impression of change, and clinical global improvement will be assessed simultaneously with the assessment of goal attainment. The interactions between GAS T-scores and other clinical scales or clinical characteristics, including baseline age and sex, will be analyzed, followed by a discussion on the effectiveness of adopting the GAS for BMS. Results The information gleaned from phase 1 will help train practitioners and develop the use of GAS for BMS. In phase 2, analyzing the GAS T-score, a quantitative assessment, will accurately reveal patient outcomes and satisfaction. The effectiveness of using the GAS and some factors contributing to patient satisfaction will be revealed by analyzing the interaction between the T-score and other clinical scales. Conclusions In addition to revealing the usefulness of GAS for BMS, we believe this study will prompt further investigations to clarify the factors contributing to patient satisfaction and shed light on a new treatment strategy that reinforces the previous treatments for BMS.

The effective perospirone augmentation with clonazepam for treatment-resistant burning mouth syndrome: A case report.

Burning mouth syndrome (BMS) is characterized by burning sensations in the oral region without corresponding abnormalities and is often accompanied by uncomfortable sensations. Herein, we present cases of BMS in which the remaining uncomfortable sensations improved with perospirone augmentation with clonazepam. Case 1: A 61-year-old man complained of a burning pain in his tongue, a sensation of dryness and discomfort as if his tongue was sticking to a palatal plate. With the diagnosis of BMS, psychopharmacotherapy was initiated with amitriptyline. At the dose of amitriptyline 50 mg, the pain lessened but uncomfortable sensations persisted. Further attempts to alleviate symptoms by combining aripiprazole with amitriptyline, aripiprazole with mirtazapine, or aripiprazole with clonazepam were limited; however, nearly all symptoms were relieved by a combination of perospirone 8.0 mg with clonazepam 1.5 mg. Case 2: A 51-year-old woman complained of a burning sensation along with oral dryness and crumb-like feeling on her tongue. She was diagnosed with BMS and began treatment with amitriptyline. Her burning sensation improved at the dose of 25 mg, but uncomfortable sensations persisted. Augmentation of amitriptyline with aripiprazole, aripiprazole either with valproate, mirtazapine, or clonazepam failed to produce a significant improvement. However, a regimen of perospirone 6.0 mg and clonazepam 1.5 mg relieved the crumb-like sensation and pain and culminated in a stabilized condition. The reported cases suggested that multiple approaches targeting the dopaminergic circuit in basal ganglia involving the serotoninergic and GABA systems, through the administration of perospirone with clonazepam is an effective adjunctive treatment for the remaining uncomfortable sensations in patients with BMS.

Conformational folding of mycobacterial methoxy- and ketomycolic acids facilitated by α-methyl trans-cyclopropane groups rather than cis-cyclopropane units.

The oxygenated long-chain mycolic acids from many mycobacteria are characterized by the presence of mid-chain cyclopropane groups, which can have either cis-configuration or trans-configuration with an adjacent methyl branch. To determine the effect of these functional groups on mycolic acid conformation, surface pressure (π) versus mean molecular area isotherms of methoxy- (MeO-) mycolic acids (MAs) from Mycobacterium kansasii, Mycobacterium tuberculosis (Mtb) Canetti and Mtb H37Ra, and of keto-MAs from Mycobacterium avium-intracellulare complex (MAC) and Mtb H37Ra were recorded and analysed. The MeO- and keto-MAs from Mtb H37Ra, containing scarcely any trans-cyclopropyl groups, apparently took no fully folded 'W-form' conformations. Keto-MA from MAC, whose trans-cyclopropyl group content is nearly 90 %, showed a very solid W-form conformation. MeO-MAs from M. kansasii and Mtb Canetti gave stable W-form conformations at lower temperatures and surface pressures and extended conformations at higher temperatures and surface pressures; their W-form conformation was not as stable as expected from their cis-cyclopropyl group content, probably because they had a wide range of constituent homologues. Energy level calculations of cis- or α-methyl trans-cyclopropane-containing model molecules and computer simulation studies confirmed the superior folding properties of the latter functional unit. The present results were compared with those of MeO- and keto-MAs from Mtb and from M. bovis Bacillus Calmette-Guérin (BCG) reported previously. Among the oxygenated MAs, those having higher trans-cyclopropane content tended to take W-form conformations more firmly, implying that the meromycolate proximal intra-chain α-methyl trans-cyclopropane groups facilitated MA folding more than cis-cyclopropane groups.

Brain perfusion asymmetry in patients with oral somatic delusions.

Oral cenesthopathy is a somatic delusion or hallucination involving the oral area and is categorized as a delusional disorder, somatic type. The pathophysiology of this intractable condition remains obscure. In this study, we clarified the pathophysiology of oral cenesthopathy by evaluating regional brain perfusion. We performed single photon emission computed tomography (SPECT) using (99m)Tc-ethylcysteinate dimer in 16 subjects (cenesthopathy:control = 8:8). The SPECT images were visually assessed qualitatively, and quantitative analyses were also performed using a three-dimensional stereotactic region-of-interest template. The visual assessment revealed a right > left perfusion asymmetry in broad areas of the brain among the patients. The quantitative analysis confirmed that the regional cerebral blood flow values on the right side were significantly larger than those on the left side for most areas of the brain in the patients. A comparison of the R/(R + L) ratios in both groups confirmed the significant brain perfusion asymmetry between the two sides in the callosomarginal, precentral, and temporal regions in the patients. Qualitative evaluation of the SPECT images revealed right > left brain perfusion asymmetry in broad regions of the brain. Moreover, the quantitative analyses confirmed the perfusion asymmetry between the two sides in the frontal and temporal areas. Those may provide the key for elucidation of the pathophysiology of oral cenesthopathy.

Dental conditions in patients with medically unexplained oral symptoms.

Background/purpose: Dentists sometimes struggle with treating patients with unexplained symptoms, known as oral psychosomatic disorders, that do not improve with conventional treatment. Oral psychosomatic disorders do not fit the definition of psychosomatic diseases in internal medicine. To ensure appropriate dental treatment, it is important for general dentists to distinguish between oral psychosomatic disorders and psychosomatic diseases. However, relevant evaluation methods have not yet been developed. The DMFT index is widely used as an indicator of the caries status. The purpose of this study was to compare the DMFT index scores of patients with oral psychosomatic. Materials and methods: The DMFT scores of 2202 patients with oral psychosomatic disorders, 145 psychiatric inpatients, and 3940 general dental patients were statistically compared. The DMFT of patients with oral psychosomatic disorders was further compared based on the presence or absence of psychiatric history and disease. Results: The median DMFT scores of oral psychosomatic disorder patients, psychiatric inpatients, and general dental patients were 16, 22, and 10, respectively, showing a significant difference. No significant differences were found in the DMFT scores based on the presence or absence of psychiatric history in oral psychosomatic disorder patients. Conclusion: The intraoral environment of patients with oral psychosomatic disorders was worse than that of general dental patients but better than that of psychiatric inpatients. General dentists could suspect psychiatric and oral psychosomatic disorders based on the state of patients' oral environment.

A case with burning mouth syndrome followed by dementia with Lewy bodies: a case report.

Burning mouth syndrome (BMS) is characterized by persistent oral burning sensations without corresponding organic findings. Dementia with Lewy bodies (DLB) is a common type of dementia and generally presents visual hallucination and parkinsonism as motor dysfunction besides cognitive decline. In this case report, we present a case in which DLB emerged during the treatment for BMS, with a relatively positive outcome for BMS. A 74 years-old female complained of burning pain in her mouth and a subsequent decrease in food intake. Following a diagnosis of BMS, pharmacotherapy was initiated. BMS was much improved with mirtazapine 15 mg and aripiprazole 1.0 mg, leading to the restoration of her food intake by day 180. However, BMS flared up again triggered by deteriorating physical condition of herself and that of her husband. With aripiprazole 1.5 mg and amitriptyline 25 mg, her BMS gradually improved by day 482. However, by day 510, an increase in anxiety was noted, accompanied by the occasionally misidentification of her husband on day 566. Her cognitive impairment and disorientation were also reported by her husband on the day 572, she was then immediately referred to a neurologist specialized dementia and diagnosed with DLB on the day 583. Her treatment was adjusted to include the prescription of rivastigmine which was titrated up to 9.0 mg. Considering the potential impact of amitriptyline on cognitive function, it was reduced and switched to mirtazapine; however, her oral sensations slightly got worse. Following the consultation with her neurologist, amitriptyline 10 mg was reintroduced and aripiprazole was discontinued on day 755. Remarkably, BMS gradually improved without deteriorating DLB. This case indicated the reaffirmed necessity of careful interviews for changes in daily life not only with the patients but also with their families through the medical assessments. It highlights the vigilance regarding potential cognitive decline underlying or induced as an adverse event especially when treating elderly patients with BMS. While the interaction between BMS and DLB remains unclear, this case underscores the importance of prudent diagnosis and constructing collaboration with specialists in managing BMS with the early phase of DLB.

Clinical Features and Variations of Pain Expressions in 834 Burning Mouth Syndrome Patients With or Without Psychiatric Comorbidities.

Introduction Burning mouth syndrome (BMS) is characterized as chronic burning pain or unpleasant discomfort in the oral region without any corresponding clinical abnormalities. The aim of this study is to investigate the difference in clinical features and the variations of pain expressions between BMS patients with and without psychiatric comorbidities. Methodology The patients with BMS who first visited between April 2016 and March 2020 were involved and the clinical data including the presence of psychiatric comorbidities and scores of self-rating depression scale (SDS), pain catastrophizing scale (PCS), and pain quality from short-form McGill pain questionnaire (SF-MPQ) were collected retrospectively. Results In 834 patients with BMS (700 females, 63.9 ± 13.1 years old), 371 patients (44.5%) had psychiatric comorbidities. There was no significant between-group difference in demographic data. However, significantly higher scores were observed in SDS (p < 0.001) and PCS (p < 0.001) in the patients with psychiatric comorbidities. Moreover, the patients with psychiatric comorbidities showed significantly stronger pain intensity (p < 0.001) besides higher scores of each descriptor in SF-MPQ. In addition, they had chosen more descriptors in SF-MPQ (p < 0.001); furthermore, the number of selected pain descriptors showed a stronger correlation with PCS than with SDS regardless of the presence of psychiatric comorbidities. Conclusion BMS patients may complain of various pain expressions regardless of the psychiatric comorbidities; however, more severe complaints relating to high pain catastrophizing are more likely in patients with psychiatric comorbidities. These results suggested that underlying anxiety exacerbated the variety of pain expressions in BMS patients with psychiatric comorbidities.

Case series of drug-induced open bite: Extrapyramidal symptoms related to psychotropic medications.

Introduction: Drug-induced open bite is one of the extrapyramidal symptoms with abnormal tonus of muscles and is rarely recognized in dentistry. This is a retrospective case study to investigate clinical characteristics including detailed complaints in patients with drug-induced open bite. Methods: Of the outpatients who first visited the psychosomatic dental clinic at the Tokyo Medical and Dental University Hospital between September 2013 and September 2022, the patients diagnosed with drug-induced open bite were involved in this study. The clinical characteristics including sex, age, detailed complaints, duration of illness, abnormal findings, psychotropic medications, and other medications that were taken at the first examination, psychiatric comorbidities, the duration of psychiatric diseases, and other medical histories were collected retrospectively by reviewing their medical chart. Results: Drug-induced open bite was found in 11 patients [women: 7, men: 4, median of age: 49 (36.5, 53) years old]. Difficulty in eating especially chewing was the major complaint (9/11, 81.6%) with the duration of illness as 48.0 (16.5, 66) months. Various degrees of open bite were observed. While some showed no occlusal contact on frontal teeth, some showed occlusal contact only on the second molars; moreover, the jaw showed a horizontal slide in a few patients. Three cases could be followed up for prognosis; while in one case the drug-induced open bite improved with 6 months of follow-up, two cases did not improve, and one showed extrusion of molars. All of them had psychiatric comorbidities with the most common diagnosis being schizophrenia (n = 5) and depression (n = 5) followed by insomnia (n = 1) and autism spectrum disorder (n = 1) including duplicated diagnosis. Nine patients (81.6%) had been undergoing treatment with antipsychotics of which three patients were also taking antidepressants. Discussion: Although a drug-induced open bite is a rare symptom, prudent medical interviews about symptoms, psychiatric comorbidities, and psychotropic medication history besides oral assessment are necessary to provide a precise diagnosis and appropriate management in collaboration between dentists and psychiatrists.

Case Report: Auditory Hallucination Induced by Amitriptyline for the Treatment of Atypical Odontalgia.

Auditory hallucination is usually associated with psychiatric diseases and organic brain illness. It was rarely found as adverse events of antidepressants. Amitriptyline is considered as one of the first line medications for the psychopharmacotherapy of chronic pain including atypical odontalgia (AO) which shows chronic tooth pain without corresponding abnormalities. Anticholinergic adverse events induced by amitriptyline are usually bearable and not critical since the prescription dose is very low for the patients with AO. This is a first case report about the AO patients who showed auditory hallucination by the low dose of amitriptyline. A 43-years-old female, housewife, complained chronic toothache following dental procedures and was diagnosed as AO. Amitriptyline was initially prescribed 25 mg and gradually increased up to 60 mg with the improvement of AO symptoms in 7 months. Although the temporary recurrence was observed following to the retreatment of prosthodontic dental procedures, it improved in a few weeks. Therefore, the dose of amitriptyline was decreased, and the continuation dose was set 30 mg. In 24 months, the AO symptoms were very much improved; however, she reported that she had been heard the voices at midnight for a year. The voices were neighborhoods' and talking about the noise troubles she had claimed before. She had not realized that the voices were auditory hallucination since they were heard only at midnight infrequent and not bothering her daily life. At the time she reported auditory hallucination, she worried whether organic brain diseases are hiding because the frequency of voices was increased and sometimes occurred in daytime. The adverse event of amitriptyline was suspected since she had never had psychotic symptoms before. Amitriptyline was decreased and continued with the dose of 25 mg. Magnetic resonance imaging and psychiatric consultation revealed no abnormality of brain and in psychiatric aspects. After final prosthodontic treatment, the amitriptyline was discontinued in 30 months. Two months after the discontinuation, auditory hallucination was almost disappeared with no recurrence of AO. The present case report suggests that amitriptyline has possibility to induce auditory hallucination even in conventional dose throughout the treatment of chronic pain including AO.

The Effectiveness and Adverse Events of Amitriptyline and Aripiprazole in Very Elderly Patients With BMS.

Burning mouth syndrome (BMS) is defined by chronic oral burning sensations without any corresponding abnormalities. Besides amitriptyline, aripiprazole has been reported as a possible medication to manage BMS. However, especially for elderly patients, the adverse events of these medications would be a problem. The aim of the present study was to investigate the differences in the effectiveness and adverse events of amitriptyline and aripiprazole in very elderly patients with BMS. This is a retrospective comparative study of 80 years old and older patients with BMS who were initially treated with amitriptyline or aripiprazole and who were new outpatients of our department from April 2017 to March 2020. All clinical data, including sex, age, comorbid physical diseases, comorbid psychiatric disorders, the prescribed doses (initial, maximum, and effective dose), prognosis, and adverse events, were collected from their medical charts. Each medication was selected considering their medical history. Amitriptyline was prescribed in 13 patients (11 women, 82.3 ± 2.1 years old) and aripiprazole was prescribed in 27 patients (26 women, 84.2 ± 3.8 years old). There were no significant between-group differences in sex, age, duration of illness, pain intensity, salivation, and psychiatric comorbidity at the first examination. Amitriptyline clinically improved more patients (7 patients, 53.8%) with the effective dose of 10 (7.5, 15.0) mg than aripiprazole (11 patients, 40.7%) of which the effective dose was 1.0 (0.5, 1.5) mg, although there were no significant between-group differences. The adverse events of amitriptyline were found in 9 patients (69.2%) and most patients had constipation (46.2%). For aripiprazole, 7 patients (25.9%) showed adverse events, most of them reported sleep disorder (11.1%). Amitriptyline had significantly longer duration taking medication (p = 0.021) and lower discontinuation (p = 0.043) despite of higher occurrence rate of adverse events (p = 0.015) compared to aripiprazole. These results suggest that both psychopharmacotherapies with a low dose of amitriptyline and aripiprazole are effective for the very elderly patients with BMS. Furthermore, aripiprazole may have some advantages in the adverse events compared to amitriptyline; however, the low dose amitriptyline monotherapy may have more benefit in the effectiveness and tolerability over prudent collaboration with primary physicians.

Phantom bite syndrome: Revelation from clinically focused review.

Phantom bite syndrome (PBS), also called occlusal dysesthesia, is characterized by persistent non-verifiable occlusal discrepancies. Such erroneous and unshakable belief of a "wrong bite" might impel patients to visit multiple dental clinics to meet their requirements to their satisfaction. Subsequently, it takes a toll on their quality of life causing, career disruption, financial loss and suicidal thoughts. In general, patients with PBS are quite rare but distinguishable if ever encountered. Since Marbach reported the first two cases in 1976, there have been dozens of published cases regarding this phenomenon, but only a few original studies were conducted. Despite the lack of official classification and guidelines, many authors agreed on the existence of a PBS "consistent pattern" that clinicians should be made aware. Nevertheless, the treatment approach has been solely based on incomplete knowledge of etiology, in which none of the proposed theories are fully explained in all the available cases. In this review, we have discussed the critical role of enhancing dental professionals' awareness of this phenomenon and suggested a comprehensive approach for PBS, provided by a multidisciplinary team of dentists, psychiatrists and exclusive psychotherapists.

Personality Traits in Burning Mouth Syndrome Patients With and Without a History of Depression.

Objectives: So far, the strong link between neuroticism, chronic pain, and depression has been well-documented in literatures. Some suggested that they might share etiological factors, thus resulting in overlapping constructs. However, such effect has never been tested in burning mouth syndrome (BMS) patients, a complex phenomenon influenced by both neuropathic and psychopathological factors. We aim to clarify how personality affects individual's pain and pain-related experiences. Methods: Two hundred forty-eight patients with BMS provided demographic information and psychiatric history; completed Ten-Item Personality Inventory, a Visual Analog Scale of pain, and McGill Pain Questionnaire; and provided adequate parameters of depressive state, catastrophizing thinking, and central sensitization. Results: BMS patients with depression history suffered more severe clinical symptoms and scored higher in neuroticism and less in openness and extraversion than did those without psychiatric diagnoses. After age, sex, and duration of pain were controlled, neuroticism in BMS patients with depression correlates with affective dimension of pain. Instead, if psychiatric history is absent, neuroticism correlates with sensory dimension and pain intensity. In both groups, higher neuroticism, unlike other personality facets, contributed to a more severe clinical condition. Conclusion: Of the five traits, neuroticism appears to be the most crucial dimension associated with the pain symptoms and patient's conditions. This study implies that management of pain must extend beyond solely providing pain-relieving medication and must require a holistic and multidisciplinary approach.
