FLOX (5-fluorouracil + leucovorin + oxaliplatin) chemotherapy for colorectal cancer leads to long-term orofacial neurotoxicity: a STROBE-guided longitudinal prospective study. Int J Clin Oncol 2020; 25:2066-2074. [PMID: 32761281 DOI: 10.1007/s10147-020-01757-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Accepted: 07/20/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Colorectal carcinoma (CRC) is widely treated by chemotherapy based on an intensely neurotoxic drug: oxaliplatin (OXL). We objective to evaluate prospectively the orofacial neurotoxicity during FLOX (fluorouracil + leucovorin + OXL) chemotherapy. METHODS So, 46 patients with CRC were prospectively evaluated during FLOX chemotherapy by 3 cycles (C) of 6 weeks (W) each. We weekly applied the orofacial section of the Acute and Chronic Neuropathy Questionnaire of Common Toxicity Criteria for Adverse Events of the National Cancer Institute of the United States of America (Oxaliplatin-specific neurotoxicity scale). Patients were asked the following concerning the severity (scores 0-5) of orofacial symptoms: jaw pain, eyelids drooping, throat discomfort, ear pain, tingling in mouth, difficulty with speech, burning or discomfort of the eyes, loss of any vision, feeling shock/pain down back and problems breathing. We summed the scores (0-50) and evaluated the clinicopathological data. Friedman/Dunn, Chi square and multinomial regression logistic tests were used (SPSS 20.0, p < 0.05). RESULTS There was a significant increase in sum of orofacial neurotoxicity from baseline to C1.W3, C2.W1 and C3.W5 (p < 0.001) due increase in scores of jaw pain (p < 0.001), eyelids drooping (p = 0.034), throat discomfort (p < 0.001), ear pain (p = 0.034), tingling in mouth (p = 0.015), burning/discomfort of your eyes (p < 0.001), loss of any vision (p < 0.001), feeling shock/pain down back (p < 0.001), problems with breathing (p = 0.045), but not difficulty with speech (p = 0.087). Women (p = 0.021) and young patients (p = 0.027) had significant higher prevalence of orofacial neurotoxicity. CONCLUSIONS FLOX-related orofacial neurotoxicity begins acutely and remains long term with increased incidence in women and younger patients.

Abstract
Objectives Tooth wear is a common finding in adult patients with dental sleep disorders. The aim of this paper was to review the literature on the possible associations between tooth wear and the following dental sleep disorders: sleep‐related oro‐facial pain, oral moistening disorders, gastroesophageal reflux disease (GERD), obstructive sleep apnoea syndrome (OSAS) and sleep bruxism. Methods A PubMed search was performed on 1 June 2018 using MeSH terms in the following query: Tooth Wear AND (Facial Pain OR Temporomandibular Joint Disorders OR Xerostomia OR Sialorrhea OR Gastroesophageal Reflux OR Sleep Apnea Syndrome OR Sleep Bruxism). Results The query yielded 706 reports on tooth wear and the mentioned dental sleep disorders. Several associations between tooth wear and the dental sleep disorders were suggested in the literature. It could be concluded that: (a) tooth wear is associated with dental pain and/or hypersensitivity; (b) oral dryness is associated with tooth wear, oro‐facial pain and sleep bruxism; (c) GERD is associated with tooth wear, oro‐facial pain, oral dryness, OSAS and sleep bruxism; (d) OSAS is associated with oral dryness, GERD and sleep bruxism; and (e) sleep bruxism is associated with tooth wear. Conclusions Tooth wear is associated with the dental sleep disorders oro‐facial pain, oral dryness, GERD and sleep bruxism. The dental sleep disorders are interlinked with each other, which leads to indirect associations as well, and makes the consequences of each single condition difficult to disentangle. Knowledge of these associations is clinically relevant, but more research is needed to confirm their validity.

Abstract
Background The aim of this study was to investigate the association between work-related factors and temporomandibular disorders (TMD) among female full-time employees using representative data from a national population-based survey. Methods Data from the Fourth Korea National Health and Nutrition Examination Survey IV (2007–2009) were used to analyze 1,612 women. Complex samples logistic regression was applied for adjusting for general characteristics and work-related factors to examine the association between work-related factors and TMD. Results The prevalence of TMD was 12.8% in this study population. With respect to age, educational status, marital status, problem drinking, exercise, and stress, there were statistically significant differences in the prevalence of TMD. In logistic regression analyses on complex samples, based on 40 h or less per week, odds ratios (ORs) for respondents who worked 40–48 working hours, 49–60 working hours, and more than 60 h were 1.16 (95% confidence interval (CI) 0.69–1.94), 1.41 (95% CI 0.79–2.54), and 2.43 (95% CI 1.29–4.59), after adjusting for general characteristics, working schedule, employment status, and occupation. Conclusions This study found that long working hours were significantly associated with TMD in Korean female full-time employees.

Abstract
Background Temporomandibular disorders (TMD) is an umbrella term for pain and dysfunction involving the masticatory muscles and the temporomandibular joints (TMJs). TMD is the most common orofacial pain condition. Its prominent features include regional pain in the face and preauricular area, limitations in jaw movement, and noise from the TMJs during jaw movements. TMD affects up to 15% of adults and 7% of adolescents. Chronic pain is the overwhelming reason that patients with TMD seek treatment. TMD can associate with impaired general health, depression, and other psychological disabilities, and may affect the quality of life of the patient. Assessment Evaluations indicate that the recently published Diagnostic Criteria for TMD (DC/TMD) are reliable and valid. These criteria cover the most common types of TMD, which include pain-related disorders (e.g., myalgia, headache attributable to TMD, and arthralgia) as well as disorders associated with the TMJ (primarily disc displacements and degenerative disease). As peripheral mechanisms most likely play a role in the onset of TMD, a detailed muscle examination is recommended. The persistence of pain involves more central factors, such as sensitization of the supraspinal neurons and second-order neurons at the level of the spinal dorsal horn/trigeminal nucleus, imbalanced antinociceptive activity, and strong genetic predisposition, which also is included in DC/TMD. Conclusion The etiology is complex and still not clearly understood, but several biological and psychosocial risk factors for TMD have been identified. Several studies indicate that patients with TMD improve with a combination of noninvasive therapies, including behavior therapy, pharmacotherapy, physical therapy, and occlusal appliances. More stringently designed studies, however, are needed to assess treatment efficacy and how to tailor treatment to the individual patient.

Abstract
Oro-facial pain research has during the last decades provided important novel insights into the basic underlying mechanisms, the need for standardised diagnostic procedures and classification systems, and multiple treatment options for successful rehabilitation of the patient in pain. Notwithstanding the significant progress in our knowledge spanning from molecules to chair, there may also be limitations in our ability to integrate and interpret the tremendous amount of new data and information, in particular in terms of the clinical implications and overriding conceptual models for oro-facial pain. The aim of the present narrative review is to briefly summarise some of the current thoughts on oro-facial pain mechanisms and recent attempts to identify biomarkers and risk factors leading to the proposal of a new risk assessment diagram for oro-facial pain (RADOP) and a provocative new concept based on stochastic variation between multiple risk factors. Finally, the implications for novel management strategies will briefly be discussed.

Abstract
BACKGROUND Orofacial pain may have an impact on quality of life. It may affect the overall well-being of an individual. OBJECTIVE To assess the prevalence of orofacial pain and its impact on quality of life in early adolescents in Indore city, India. METHODS This was a cross-sectional study which included a total of 800 children selected from various public and private schools located in Indore city, India. A questionnaire was developed which collected information on sociodemographic characteristics and previous dental visits. The severity of pain was assessed using Von Korff pain scale and quality of life using the General Health Questionnaire 12 (GHQ-12). The chi-square test and logistic regression analysis were performed. RESULTS The overall prevalence of orofacial pain was found to be 17.9%. Toothache (10.1%) was found to be the most prevalent orofacial pain followed by temporomandibular joint pain (4.3%). The highest severity of pain (Grades 3 and 4) was reported for toothache followed by temporomandibular joint pain. The results of the logistic regression model showed that the prevalence of orofacial pain (odds ratio=7.18, p-value<0.0001a) was strongly associated with poor quality of life. CONCLUSION The orofacial pain has a negative influence on the quality of life of adolescents. Effective policies should be created to improve the quality of life of adolescents focusing on oral health education and prevention of oral diseases.

Abstract
Background Pain is considered a key symptom associated with possible impairment of oral-health-related quality of life and its assessment is important for the planning and evaluation of preventive and treatment effort. The tools for assessing pain must therefore be valid and consistent. The objective of this study was to assess dental patients’ level of pain based on the clinical diagnosis of their dental condition and the correlation between two pain assessment scales, Visual analogue scale (VAS) and the Full Cup Test (FCT), for the assessment of pain among dental patients. Methods A total of 185 patients presenting at the University of Benin Teaching Hospital dental outpatient clinics with various forms of orofacial pain were included in this study. The mean VAS scores and mean FCT scores for the different dental conditions were compared. Agreement between VAS and FCT was evaluated using the Intra-class correlation (ICC) coefficients and Cronbach alpha coefficient was also calculated to assess consistency of the two pain scales. Results Majority i.e. 95.1, 96.2 and 100% who presented with acute pulpitis, acute apical periodontitis and pericoronitis respectively, presented with moderate to severe pain levels (p < 0.05). Only 25.9 and 4% who presented with chronic marginal gingivitis and chronic pulpitis respectively presented with no pain (p < 0.05). A large proportion (75%) of patients with no pain had single diagnosis while more than half (52.1%) of those who presented with severe pain had multiple diagnoses (p = 0.025). The mean VAS and FCT scores for acute pain were 6.1 ± 2.1 and 5.9 ± 2.4 respectively and for chronic pain 3.9 ± 2.7 and 3.7 ± 2.7 respectively (P = 0.001). The interclass correlation coefficient revealed that the mean VAS and FCT scores were statistically correlated and reliable with a Cronbach alpha coefficient of 0.85. Conclusion It can be concluded that patients who presented with either acute or chronic dental conditions may experience moderate to severe level of pain, with patients with multiple diagnoses experiencing more severe pain, and there is a correlation between the VAS and FCT for pain assessment among dental patients.

Abstract
Objectives To determine the prevalence of facial pain and to examine the hypothesis that symptoms are associated with socio-demographic, dental, adverse psychological factors and pain elsewhere in the body. Material and Methods Cross-sectional population data were obtained from UK Biobank (www.ukbiobank.ac.uk/) study which was conducted in 2006 - 2010 and recruited over 500,000 people. Results The overall prevalence of facial pain (FP) was 1.9% (women 2.4%, men 1.2%) of which 48% was chronic. The highest prevalence was found in the 51 - 55 age group (2.2%) and the lowest in the 66 - 73 age group (1.4%). There was a difference in prevalence by ethnicity (0.8% and 2.7% in persons reporting themselves as Chinese and Mixed respectively). Prevalence of FP significantly associated with all measures of social class with the most deprived and on lowest income showing the highest prevalence (2.5% and 2.4% respectively). FP was more common in individuals who rated themselves as extremely unhappy, had history of depression and reported sleep problems. Smoking associated with increase in reporting FP while alcohol consumption had inverse association. FP associated with history of painful gums, toothache and all types of regional pain. Conclusions This is the largest ever study to provide estimates of facial pain prevalence. It demonstrates unique features (lower prevalence than previously reported) and common features (more common in women) and confirms multifactorial aetiology of facial pain. Significant association with psychological distress and a strong relationship to pain elsewhere in the body suggests that aetiology is not specific to this regional pain.

Abstract
BACKGROUND The objective of this study was to investigate the effects of experimental sleep deprivation (SD) on the temporomandibular joint (TMJ) in rats by examining pain-related factors and to determine the possible involvement of estrogen and NF (nuclear factor) κB signaling in the TMJ synovial membrane. METHODS The influence of SD, conducted in rats using the modified multiple platform method, was estimated by observing behavioral manifestations and examining changes in serum hormone levels. The morphologic changes of synovial tissue were observed with light microscopy and the serum levels of estrogen were measured by radioimmunoassay. Activation of NF-κB in the synovial membrane was examined using an immunofluorescence technique, and the expression levels of interleukin (IL) 1β, IL-6, tumor necrosis factor α, cyclooxygenase 2, and inducible nitric oxide synthase were measured with real-time polymerase chain reaction. RESULTS The SD group showed evidence of elevated anxiety and stress, and increased plasma levels of estradiol compared with the control group. The activity of NF-κB was significantly enhanced and translocation of NF-κB p65 was evident in the synovial membrane after SD. The expression of pain-related factors IL-1β, IL-6, cyclooxygenase-2, tumor necrosis factor α, and inducible nitric oxide synthase in the synovial membrane significantly increased after SD. CONCLUSIONS These results indicate that SD increases serum levels of estrogen and induces alterations in pain-related factors in the TMJ. The NF-κB pathway has been associated with the regulation of these inflammatory cytokines and plays an important role in temporomandibular disorders.

Abstract
UNLABELLED Case-control studies have consistently associated psychosocial factors with chronic pain in general, and with temporomandibular disorders (TMD) specifically. Moreover, a handful of prospective studies suggest that preexisting psychosocial characteristics represent risk factors for new onset TMD. The current study presents psychosocial findings from the baseline case-control study of the Orofacial Pain Prospective Evaluation and Risk Assessment (OPPERA) cooperative agreement. For this study, 1,633 TMD-free controls and 185 TMD cases completed a battery of psychosocial instruments assessing general psychosocial adjustment and personality, affective distress, psychosocial stress, somatic awareness, and pain coping and catastrophizing. In bivariate and demographically adjusted analyses, odds of TMD were associated with higher levels of psychosocial symptoms, affective distress, somatic awareness, and pain catastrophizing. Among controls, significant gender and ethnic group differences in psychosocial measures were observed, consistent with previous findings. Principal component analysis was undertaken to identify latent constructs revealing 4 components: stress and negative affectivity, global psychosocial symptoms, passive pain coping, and active pain coping. These findings provide further evidence of associations between psychosocial factors and TMD. Future prospective analyses in the OPPERA cohort will determine if the premorbid presence of these psychosocial factors predicts increased risk for developing new onset TMD. PERSPECTIVE This article reports baseline psychosocial findings from the OPPERA Study, a large prospective cohort study designed to discover causal determinants of TMD pain. Findings indicate significant differences between TMD cases and TMD-free controls across multiple psychosocial constructs, and future analyses will determine whether these psychosocial factors increase risk for new onset TMD.

Abstract
Sleep bruxism (SB) is a common sleep-related motor disorder characterized by tooth grinding and clenching. SB diagnosis is made on history of tooth grinding and confirmed by polysomnographic recording of electromyographic (EMG) episodes in the masseter and temporalis muscles. The typical EMG activity pattern in patients with SB is known as rhythmic masticatory muscle activity (RMMA). The authors observed that most RMMA episodes occur in association with sleep arousal and are preceded by physiologic activation of the central nervous and sympathetic cardiac systems. This article provides a comprehensive review of the cause, pathophysiology, assessment, and management of SB.

Abstract
OBJECTIVE The objective of this study was to investigate the effects of psychological stress on temporomandibular disorder (TMD). STUDY DESIGN A communication box was used to induce psychological stress (PS) in rats. Then, the ultrastructure of temporomandibular was observed using scanning electron microscopy. Interleukin-1 (IL-1) and IL-6 were measured with reverse transcription polymerase chain reaction. RESULTS The PS group showed evidence of ultrastructural changes in the condyle and articular disk after stimulation, i.e., incomplete gelatinlike material was observed on the condyle after 1 week of PS, wider waves on the articular disk and exposed condylar collagen were observed after 3 weeks of PS, and cracks were apparent on the surface of the condyle. The expression of IL-1 and IL-6 in the condyle cartilage significantly increased after exposure to psychological stress. CONCLUSIONS These results indicate that psychological stress induces ultrastructure alterations in the temporomandibular joint and plays an important role in TMD.

Abstract
Background and aims
Orofacial pain is one of the most common reasons for attendance at the dental clinic. The prevalence and the sources of orofacial pain vary from place to place and patients’ response to pain also differs. The aim of this study was to determine the prevalence and pattern of orofacial pain as well as the factors influencing patients’ response to orofacial pain among patients presenting for dental treatment in our center.
Materials and methods
Consecutive patients presenting with orofacial pain at the Dental Center, University of Port Harcourt Teaching Hospital during the one-year period of the study were recruited into the study. Patients’ demographic data were collected and recorded in special forms. Patients were later examined to confirm the specific cause of pain. This was also recorded. Data generated were analyzed using SPSS for Windows.
Results
Four hundred and forty-eight patients out of the 2,426 patients seen during the study period had orofacial pain, yielding a prevalence rate of 18.5%. There were 255 females and 193 males with most patients in the 17-27-year age group (49.1%). Lower jaw was commonly affected. Most patients presented after a period of at least one month, with severe and spontaneous pain. Most patients had drug therapy before presentation. Caries was the most common source of orofacial pain.
Conclusion Orofacial pain was not uncommon in our center and it accounted for about 20% of patients’ attendance in the center. Dental caries and periodontal diseases were the most common sources of orofacial pain while temporomandibu-lar joint pain and atypical facial pain were not common in our center. Young adults and females were most commonly affected.
