Comparison of six antibody assays and two combination assays for COVID-19
[Introduction] In this work, six SARS-CoV-2-specific antibody assays were evaluated, namely, two pan-immunoglobulin (pan-Ig) assays [Roche Elecsys Anti-SARS-CoV-2 (named "Elecsys" in this study) and the PerkinElmer SuperFlex™ Anti-SARS-CoV-2 Ab Assay (SuperFlex_Ab)], two IgM assays [SuperFlex™ Anti-SARS-CoV-2 IgM Assay (SuperFlex_IgM) and YHLO iFlash-SARS-CoV-2 IgM (iFlash_IgM)], and two IgG assays [SuperFlex™ Anti-SARS-CoV-2 IgG Assay (SuperFlex_IgG) and iFlash-SARS-CoV-2 IgG (iFlash_IgG)]. Combination assays of SuperFlex™ (SuperFlex_any) and iFlash (iFlash_any) were also evaluated. [Methods] A total of 438 residual serum samples from 54 COVID-19 patients in the COVID-19 group and 100 samples from individuals without evidence of SARS-CoV-2 infection in the negative control group were evaluated. [Results] In the early stage of COVID-19 infection, within 14 days of symptom onset, the seropositive rate was lower than that of the late stage 15 days after onset (65.4% vs 99.6%). In the total period, the pan-Ig and IgG assays had higher sensitivity (90.8–95.3%) than the IgM assays (36.5–40.7%). SuperFlex_Ab and SuperFlex_any had higher sensitivity than Elecsys and SuperFlex_IgG (p < 0.05). The specificity of all the assays was 100%, except for SuperFlex_IgM (99.0%). The concordance rate between each assay was higher (96.4–100%) in the late stage than in the early stage (77.4–98.1%). [Conclusion] For the purpose of COVID-19 diagnosis, antibody testing should be performed 15 days after onset. For the purpose of epidemiological surveillance, highly sensitive assays should be used as much as possible, such as SuperFlex_Ab, iFlash_IgG and their combination. IgM assays were not suitable for these purposes
Changes in Corrected QT Interval May Be Associated with Clinical Responses in Burning Mouth Syndrome
Backgrounds: Burning mouth syndrome (BMS) is characterized by a burning sensation of the oral mucosa in the absence of underlying dental causes. Only a minority of BMS patients will achieve satisfactory pain relief and little is known about clinical makers for the response. The objective of this study was to consider whether corrected QT interval (QTc) is a useful biomarker for clinical responses.
Methods: We conducted a single-center retrospective observational study and evaluated 51 BMS patients treated with amitriptyline. We calculated QTc changes with amitriptyline and examined the relationship between changes in QTc and visual analogue scale (VAS).
Results: Of 51 subjects, 13 (25.5%) were amitriptyline-responders and 38 (74.5%) were non-responders. The changes in QTc interval were significantly correlated with changes in VAS (Spearman's rank correlation coefficient r = 0.389, p = 0.006).
Conclusions: Changes in QTc interval may be a non-invasive estimation of clinical responses in BMS patients

Bladder dysfunction and urinary tract infection caused by abdominal pseudocyst with a ventriculoperitoneal shunt: A case report with literature review
The lower urinary tract dysfunction of the neurogenic bladder often worsens owing to dysfunction of the bladder itself. We treated a patient with spina bifida who experienced bladder dysfunction that worsened owing to an abdominal pseudocyst that developed as a complication of a ventriculoperitoneal shunt. After removal of the pseudocyst, the urinary tract infection was controlled and bladder dysfunction was alleviated to a basal level
Pharmacotherapeutic outcomes in atypical odontalgia : determinants of pain relief
Objectives: There has been considerable research which has focused on clarifying the origin of pain in patients with atypical odontalgia (AO), also known as “idiopathic toothache”, and on identifying effective treatment, but there has been limited success so far. In this study, we assessed the outcomes of treatment and attempted to identify factors that could account for pain remission in patients with AO.
Patients and methods: Data for 165 patients diagnosed with AO from June 2015 to August 2017 were retrospectively reviewed. The patients’ sex, age, duration of pain, and psychiatric history were collected, along with information on pain intensity, depressive status, and catastrophizing scores. Responses at 4 and 16 weeks from the start of treatment were observed. The associations between potentially associated factors and outcome were investigated using Bayesian model averaging.
Results: A 30% reduction in pain was reported by 38 patients (46.3%) at 4 weeks and by 54 patients (65.9%) at 16 weeks. The pain intensity decreased as the depression and catastrophizing score improved; all of the changes were statistically significant (P<0.001). Four elements, that is, patient sex, depression score at baseline, pain score at 4 weeks, and change in the catastrophizing score, explained 52.5% of the variation in final outcome between individual patients.
Conclusion: Our findings confirm the efficacy of tricyclic antidepressants (TCAs) as a treatment for AO and indicate that other medications, especially aripiprazole used in combination with a TCA, may be useful. A considerable number of patients, especially women, those with lower levels of depression at baseline, and those who responded to 4 weeks of treatment, achieved pain relief
Burning Mouth Syndrome and Atypical Odontalgia
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
Psychiatric comorbidities in patients with Atypical Odontalgia
Objective: Atypical Odontalgia (AO) is a condition characterized by tooth pain with no apparent cause. Although psychiatric comorbidity seems to be very common, it has rarely been studied. To clarify the influence of psychiatric comorbidity on the clinical features in patients with AO, we retrospectively evaluated their examination records.
Methods: Clinical features and psychiatric diagnoses of 383 patients with AO were investigated by reviewing patients' medical records and referral letters. Psychiatric diagnoses were categorized according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). We also analyzed visual analogue scale (VAS), self-rating depression scale (SDS), and the short-form McGill pain questionnaire (SF-MPQ) scores.
Results: Of the 383 patients with AO, 177 (46.2%) had comorbid psychiatric disorders. The most common were depressive disorders (15.4%) and anxiety disorders (10.1%). Serious psychotic disorders such as bipolar disorder (3.0%) and schizophrenia (1.8%) were rare. Dental trigger of AO was reported in 217 (56.7%) patients. There were no significant correlations between psychiatric comorbidities and most of the demographic features. Higher VAS and SDS scores, higher frequency of sleep disturbance, and higher ratings of “Fearful” and “Punishing-cruel” descriptors of the SF-MPQ were found in patients with psychiatric comorbidity.
Conclusions: About half of AO patients had comorbid psychiatric disorders. Dental procedures are not necessarily causative factors of AO. In AO patients with comorbid psychiatric disorders, pain might have a larger emotional component than a sensory one. VAS, SDS, and SF-MPQ scores might aid in the noticing of underlying comorbid psychiatric disorders in AO patients
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
The self-esteem and the activities of daily living in inpatients after an ischemic stroke
急性期の脳梗塞患者の自尊感情と日常生活動作の関連を明らかにするために,入院中の脳梗塞患者150人に調査協力を依頼した.調査協力の同意が得られなかった患者25人と調査前に退院された患者17人を除き,108人(72.0%)(男性74人,女性34人,平均年齢64.5(SD 12.5)才)にアンケート調査を実施した.自尊感情(Rosenberg のSelf-Esteem,以下RSE と記載)は平均29.9(SD 6.1)点,日常生活動作(Barthel index,以下BI と記載)は平均89.4(SD 16.0)点であり,RSE とBI の間にはBI が低いとRSE が低いという正の相関がみられた(Spearman のρ= 0.461,p < 0.001).また,BI が低いことと「女性である」「高齢である」「入院時の機能障害が重い」の関連が示唆された.急性期には,脳梗塞患者の日常生活動作の自立に向けた援助と,自尊感情を高める介入が必要であると考えられた.The purpose of this study was to investigate the relationship between self-esteem and the activities of daily living in inpatients after an ischemic stroke. The level of Rosenberg's Self-esteem and the Barthel index were examined. There were 108 respondents (74 males and 34 females). Based on these results, selfesteem was significantly correlated to the Barthel Index (Spearman's ρ=0.461, p<0.001). Findings indicated that low self-esteem related to dependence, and the level of dependence showed a negative association with women, the elderly and severe disability. These results suggested the necessity of rehabilitation for re-acquiring the skills of daily living and enhancement of self-esteem in patients who are dependent.広島保健学学会 特別講
