Medically unexplained symptoms

A randomized controlled trial of Eye Movement Desensitization and Reprocessing (EMDR) Therapy in the treatment of fibromyalgia

Background

In addition to pharmacological treatment, psychotherapeutic approaches are recommended for the treatment of fibromyalgia. There is a suggestion that eye movement desensitization and reprocessing (EMDR) therapy may be effective. This study aimed to investigate the impact of EMDR therapy on fibromyalgia symptoms, depression, sleep quality, and traumatic stress in fibromyalgia patients through a randomized controlled study (RCT).

Materials and methods

The sample for this study comprised 79 individuals diagnosed with fibromyalgia. Participants were randomly assigned to two groups: the "Treatment as Usual" (TAU) group and the TAU + EMDR group. Prior to the study and at six different time points (before starting the study, at the end of the 5th, 10th, and 15th sessions, 1 month later, and 3 months later), participants completed assessments, including the Fibromyalgia Impact Questionnaire (FIQ), Visual Analog Scale (VAS), Fibromyalgia ACR 2010 Diagnostic Criteria [Widespread Pain Index (WPI) and Symptom Severity Scale (SSS)], Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and Trauma Symptom Checklist-40 (TSC-40).

Results

There were no differences in the sociodemographic variables between the study and experimental groups. Analysis of variance revealed a statistically significant group effect on VAS (p = 0.019), WPI (p = 0.018), BDI (p = 0.019), and TSC-40 (p = 0.21). After applying Bonferroni correction, EMDR was found to be effective for VAS, WPI, SSS, BDI, PSQI, and TSC-40 (p <0.05).

Conclusion

The results of the current study suggest that EMDR therapy is a viable alternative treatment for fibromyalgia. We believe these findings offer robust evidence supporting the efficacy of EMDR therapy in treating fibromyalgia, particularly in the context of a randomized controlled trial (RCT). The application of EMDR therapy for the treatment of patients with fibromyalgia is likely to be beneficial.

Psychological characteristics of young adults with temporomandibular disorders, somatization and combined conditions: A multidimensional evaluation

BACKGROUND

Temporomandibular disorders and somatization have shown interrelation in many studies. The physical and psychological factors which contributed to the occurrence and relation of both conditions are yet to be determined.

OBJECTIVES

The personality traits, coping styles and psychological distress of young adults with temporomandibular disorder (TMD) and somatic symptoms were characterized together with the determination of psychological risk factors for TMDs, somatization and combined conditions.

METHODS

Participants were recruited from university-attending young adults. TMD and somatic symptoms were appraised with the short-form Fonseca Anamnestic Index and Patient Health Questionnaire-15. Psychological variables were assessed with the Big Five Personality Inventory-10, Brief-COPE Inventory and Depression, Anxiety, and Stress Scales-21. Data were evaluated using chi-squared/non-parametric tests and logistic regression analyses (α = .05).

RESULTS

Among the 507 participants (mean age 22.2 ± 1.5 years), 46.4% reported no TMD/somatic symptoms (NS) while 7.5%, 34.5% and 11.6% had TMDs only (TS), somatization only (SS) and combined TMDs-somatization (CS), respectively. Significant differences in conscientiousness (NS > SS), agreeableness (NS, TS > CS; NS > SS), dysfunctional coping, general distress, depression, anxiety and stress (CS ≥ SS > NS) were discerned. Multivariate analyses indicated that the odds of TS were increased by anxiety (OR = 1.10; 95% CI = 1.01-1.21), while the odds of SS/CS were affected by anxiety (OR = 1.15; 95% CI = 1.06-1.25/OR = 1.34; 95% CI = 0.19-1.52) and problem-focused coping (OR = 0.71; 95% CI = 0.56-0.89/OR = 0.55; 95% CI = 0.39-0.78).

CONCLUSION

Though individuals with TMDs and somatization have dissimilar psychological profiles, anxiety constantly increased their likelihood. Problem-focused coping strategies may help alleviate psychosocial and physical stressors associated with TMDs and somatization.

Pediatric Functional Neurological Symptoms Disorder: Walking Ability and Perceived Exertion Post-Pediatric Rehabilitation

BACKGROUND

Adolescents with functional neurological symptoms disorder (FNSD) commonly present walking abnormalities. Walking is influenced by 'objective' (e.g., fitness) and 'subjective' (e.g., fear) components. Rate of perceived exertion (RPE) reflects the interaction between these two components. This study compared the walking ability and RPE before and after rehabilitation of adolescents with FNSD to adolescents with moderate-to-severe traumatic brain injury (TBI). Factors predicting walking and RPE were also examined.

METHODS

Adolescents with FNSD (n = 31) and adolescents with moderate-to-severe TBI (n = 28) aged 6 to 18 years participated in the study. Participants received a multidisciplinary rehabilitation program. Six-minute walk test (6MWT) and RPE were assessed before and after rehabilitation.

RESULTS

At pre-test, the TBI group presented lower RPE than the FNSD group (3.38 ± 2.49 and 6.25 ± 2.71, respectively). In the FNSD group, pre-test 6MWT was a significant predictor of post-test 6MWT (adjusted R2 = 0.17; p = 0.01). In the TBI group, post-test 6MWT was significantly predicted by both the pre-test 6MWT and age (adjusted R2 = 0.16; p = 0.04).

CONCLUSIONS

Prior to the intervention, adolescents with FNSD perceived walking as a more difficult activity than adolescents with TBI. Post-intervention, although the intervention was effective in terms of changes in 6MWT and RPE, the 'subjective' component still contributed to the elevated RPE of the FNSD group.

Communication interventions for medically unexplained symptom conditions in general practice: A systematic review and meta-analysis of randomised controlled trials

Background

Medically unexplained symptoms (MUS) account for 3–50% of all General Practitioner (GP) consultations and are difficult to diagnose due to their unknown aetiology, symptom overlap between conditions, and lack of effective treatment options. MUS patients’ and primary care clinicians frequently face challenges during consultations, with GPs reporting difficulty identifying and classifying MUS, whilst patients report stigma and feeling illegitimised by clinicians. Communication interventions have been proposed as a method to facilitate the doctor-patient relationship and aid the management of MUS.

Aim

This systematic review aims to evaluate the effectiveness of primary care based communication interventions at improving MUS patients’ and/or clinician outcomes.

Method

Four electronic databases were searched from inception to November 2021. Two researchers independently undertook screening, data extraction and quality appraisal. Given the heterogeneous nature of the studies identified, narrative syntheses were conducted, along with meta-analyses where possible to pool data.

Results

9 papers from 10 Randomised Controlled Trials were included. The included studies displayed considerable risk of bias and poor reporting. Some limited evidence suggests that communication interventions tailored to MUS and not following a pre-specified model (such as reattribution) could improve pain, mental and physical functioning whilst reattribution training may improve clinician confidence treating MUS. However, methodological limitations mean that these findings should be interpreted with caution.

Conclusion

A range of interventions for improving communication with MUS patients in primary care have been evaluated. However, the heterogeneous nature of existing evidence and poor study quality mean we cannot conclude whether these interventions are effective. Before considering further randomised controlled trials researchers should focus on developing a new or modified communication intervention for MUS patients and their clinicians.

Association between self-reported drug hypersensitivity reactions and psychological disorders

Background

Medically unexplained physical symptoms are a well-recognized problem and, in some cases, there is a well-established relationship between behavior and psychopathological disturbances. However, the association between drug hypersensitivity reactions and psychoactive disorders stills under discussion.

Objective

Our main goal was to establish if there is an association between self-reported drug hypersensitivity reaction and psychopathology with need for psychoactive drug consumption.

Methods

Retrospective study of adult patients evaluated in a first Immunoallergology appointment because of self-reported drug hypersensitivity over 1 year and register of data concerning psychoactive drugs use. Compare the study group with patients observed for allergic respiratory disease along the same year.

Results

The study group included 70 patients that referred a total of 92 self-reported drug hypersensitivity reactions. Twenty-nine (41.4%) were under treatment with psychoactive drugs: 20 (70%) were treated with anxiolytics, 13 (18.6%) with antidepressants, 15 (21.4%) with sedatives, and 1 (1.4%) with antipsychotics. The control group included 160 patients and 38 patients (23.8%) were under treatment with psychoactive drugs: 31 (19.4%) where treated with antidepressants, 29 (18.1%) with anxiolytics, and 3 (1.9%) with sedatives. The use of psychoactive drugs in the study group is higher than in the control group (p = 0.007), the difference is especially important for sedative drugs (p < 0.001). Besides a higher use of psychoactive drugs, the study group also has a higher frequency of use of several psychoactive drug (p = 0.002).

Conclusion

Patients with a self-report drug hypersensitivity have more tendency to be under treatment with psychoactive drugs and could have more tendency to somatization. Personality traces and psychopathology must be taken into account during an allergy workup.

"This Might Be Your New Normal…" Storytelling Amidst Uncertainty and Medically Unexplained Symptoms

The medical diagnostic journey can be filled with uncertainty, anxiety, tension, and complications. This essay moves between first-person storytelling and analytic memos to illustrate defining moments of a diagnostic journey. It brings to life the complexity of navigating the healthcare system through the eyes of someone with medically unexplained symptoms (MUS). Additionally, it presses into the complex nature of the medical world and how one communicates through those tensions with healthcare professionals, loved ones, and colleagues when their illness is questioned and doubted.

Embodied Knowledge - the Phenomenon of Subjective Health Complaints reflected upon by Norwegian Psychomotor Physiotherapy specialists

Background: Many patients report subjective health complaints (SHCs) during primary health care consultations. Objective: To elucidate Norwegian Psychomotor Physiotherapy (NPMP) specialists' clinical experiences in treatment of patients suffering from SHCs. Methods: Twelve NPMP specialists were interviewed. The transcripts were qualitatively analyzed using systematic text condensation. Results: "Embodied knowledge" seemed to be an unfamiliar concept to those suffering from SHCs. The NPMP specialists regarded increased body awareness to be a vital element in the process of recovery from SHCs. Differences between NPMP specialists' professional view and that of some medical doctors were reported. Three categories emerged from the material: 1) "The process of establishing a joint understanding of subjective health complaints"; 2) "The process of increasing the patients' embodied awareness"; and 3) "The challenge of sharing embodied knowledge in inter-professional communication." Conclusion: The NPMP specialists emphasized the importance of increasing patients' consciousness of their embodied knowledge. They searched to adjust their therapeutic approaches, depending on the individual patient's specific problems and degree of emotional and/or bodily strain. The NPMP specialists experienced the importance of creating a shared understanding of the meaning embedded in SHCs between patients, NPMP specialists, and medical doctors.

Glycosylation Profiling as a Biomarker of Suboptimal Health Status for Chronic Disease Stratification

WHO defines health as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." We coined and defined suboptimal health status (SHS) as a subclinical, reversible stage of the pre-chronic disease. SHS is a physical state between health and disease, characterized by health complaints, general weakness, chronic fatigue, and low energy levels. We have developed an instrument to measure SHS, Suboptimal Health Status Questionnaire-25 (SHSQ-25), a self-reported survey assessing five health components that has been validated in various ethnical populations. Our studies suggest that SHS is associated with the major components of cardiovascular health and the early onset of metabolic diseases. Besides subjective measure of health (SHS), glycans are conceived as objective biomarkers of SHS. Glycans are complex and branching carbohydrate moieties attached to proteins, participating in inflammatory regulation and chronic disease pathogenesis. We have been investigating the role of glycans and SHS in multiple cardiometabolic diseases in different ethnical populations (African, Chinese, and Caucasian). Here we present case studies to prove that a combination of subjective health measure (SHS) with objective health measure (glycans) represents a window of opportunity to halt or reverse the progression of chronic diseases.

"I Don't Claim to Be the World's Foremost Expert, But . . . ": How Individuals "Know" Family Members Are Not Experiencing Health Issues as Severely as They Claim

To understand how individuals come to "know" that their family members are not experiencing their health issues as severely as they claim, we interviewed 32 individuals (nine men and 23 women, M age = 35.28 years, SD = 9.91 years) about a family member who they believe falsifies or exaggerates his or her health condition(s). Our analyses illuminate two interlinked processes of knowledge construction: (a) developing evidentiary standards and (b) gathering evidence. In engaging these processes, participants sought two types of consistency: correspondence with external "facts" (e.g., medical information, cultural [mis]conceptions), and internal coherence (i.e., complaints were highly self-contradictory and unpredictable or were overly predictable). When initial inconsistencies made participants doubt their family member, participants gathered additional evidence, including experiential, behavioral, and interactional evidence, to test and revise their initial suspicions. We discuss the implications of this research for theory and for families coping with illness.

Explanation of somatic symptoms by mental health and personality traits: application of Bayesian regularized quantile regression in a large population study

BACKGROUND

Somatic syndrome is one of the remarkably prevalent issues in primary health care and subspecialty settings. We aimed to elucidate multidimensional associations between somatic symptoms with major mental problems and personality traits in the framework of the quantile regression model with a Bayesian approach.

METHODS

A total of 4763 employees at Isfahan University of Medical Sciences and Health Services in Isfahan province, Iran, filled out four validated questionnaires including Hospital Anxiety and Depression Scale (HADS), NEO Questionnaire, General Health Questionnaire (GHQ) and PHQ-15 for somatic symptom severity. In addition, Functional Gastrointestinal Disorders (FGIDs) were determined using Rome IV criteria. Exploratory Factor Analysis (EFA) and Bayesian regularized quantile regression with adaptive LASSO penalization were applied for reduced dimension of somatic symptoms and variable selection and parameter estimation, respectively.

RESULTS

The 25 major somatic symptoms were grouped into four factors including general, upper gastrointestinal, lower gastrointestinal and respiratory by EFA. Stress, depression, and anxiety had significant effects on all of the four extracted factors. The effect of anxiety in each four extracted factors was more than stress and depression. Neuroticism and agreeableness had significant effects on all of the four extracted factors, generally (p < 0.05).

CONCLUSIONS

Given the high prevalence of somatic symptoms and psychosomatic complaints in correlation with the diverse range of mental co-morbidities, developing more detailed diagnostic tools and methods is crucial; nonetheless, it seems that providing better interdisciplinary approaches in general medical practice is groundwork.

Fibromyalgia syndrome pathology and environmental influences on afflictions with medically unexplained symptoms

Fibromyalgia syndrome (FMS) is a clinical disorder predominant in females with unknown etiology and medically unexplained symptoms (MUS), similar to other afflictions, including irritable bowel syndrome (IBS), chronic fatigue syndrome (CFS), post-traumatic stress disorder (PTSD), Gulf War illness (GFI), and others. External environmental stimuli drive behavior and impact physiologic homeostasis (internal environment) via autonomic functioning. These environments directly impact the individual affective state (mind), which feeds back to regulate physiology (body). FMS has emerged as a complex disorder with pathologies identified among neurotransmitter and enzyme levels, immune/cytokine functionality, cortical volumes, cutaneous innervation, as well as an increased frequency among people with a history of traumatic and/or emotionally negative events, and specific personality trait profiles. Yet, quantitative physical evidence of pathology or disease etiology among FMS has been limited (as with other afflictions with MUS). Previously, our group published findings of increased peptidergic sensory innervation associated with the arterio-venous shunts (AVS) in the glabrous hand skin of FMS patients, which provides a plausible mechanism for the wide-spread FMS symptomology. This review focuses on FMS as a model affliction with MUS to discuss the implications of the recently discovered peripheral innervation alterations, explore the role of peripheral innervation to central sensitization syndromes (CSS), and examine possible estrogen-related mechanisms through which external and internal environmental factors may contribute to FMS etiology and possibly other afflictions with MUS.
