Young people diagnosed with psychogenic nonepileptic seizures (PNES) years ago - How are they now?

BACKGROUND: Up to 30% of patients referred to epilepsy centres for drug-resistant epilepsy turn out to have psychogenic nonepileptic seizures (PNES). Patients with PNES are a very heterogeneous population with large differences in regard to underlying causes, seizures severity, and impact on quality of life. There is limited knowledge regarding the long-term seizure prognosis of youth with PNES and its influential factors. METHODS: We have performed a retrospective study on adolescents diagnosed with PNES who were receiving inpatient care at our hospital for 2-4 weeks in the period of 2012-2020. They all attended psychoeducational courses to educate them about PNES, coping with the seizures, and possible contributors to seizure susceptibility. There were 258 patients who fulfilled the inclusion criteria. We contacted them by text messages, through which they received brief information about the study and an invitation to participate. There were 62 patients (24 %) who agreed and participated in structured telephone interviews. We excluded 10 patients due to concomitant epilepsy. The mean age of the remaining 52 participants was 20.9 years (16-28 years), and 45 (87 %) were women. RESULTS: After a mean of 4.7 years (2-9 years) since discharge from our hospital, 28 patients (54 %) had been free of seizures in the last 6 months. There were 16 patients (31 %) who had better situations in regard to seizures but were not completely seizure free, while 8 patients (15 %) were either unchanged (3 patients) or worse (5 patients). There were 39 patients (75 %) who had received conversation therapy, and 37 patients (71 %) had been treated by a psychologist or psychiatrist. There were 10 patients (19 %) who had dropped out of school or work, and the percentage increased with age. There were 42 patients (80 %) who perceived their health as good or very good. CONCLUSION: Patients had a relatively favourable seizure prognosis as 54% were free of seizures and 31% had a better seizure situation, at the time of this study. However, the fact that 19% had dropped out of school or work was worrying. Young age and satisfaction with treatment were associated with being employed or receiving education. Satisfaction with perceived treatment was significantly associated with personal experience of good health. This emphasizes the importance of early diagnosis, adapted interventional measures, and long-term follow-up by healthcare for young people with PNES.

New-onset psychogenic nonepileptic seizures after intracranial neurosurgery: A meta-analysis.

BACKGROUND: The epidemiology of psychogenic non-epileptic seizures (PNES) is still unclear. Although approximately 14 million people need neurosurgical care annually, there is a dearth of thorough analysis on PNES occurrence following surgery. This study seeks to estimate the proportion of newly diagnosed PNES. METHODS: We conducted a literature search of the PubMed, Ovid, CINAHL, and Cochrane Library databases up to December 2023. We identified studies using an observational design on the occurrence of PNES in patients who underwent intracranial surgery, and confirmed diagnosis using video-EEG. Estimates are reported as proportions using random effects models. We reported both 95 % CIs and prediction intervals (PI). We assessed the risk of bias and identified the pooled odds ratio (OR) for mutually exclusive groups. The heterogeneity was investigated using the I² statistic and significance determined using Cochran's Q-test. Post-hoc Egger's regression test, and several sensitivity analyses were performed. This study was registered in PROSPERO (CRD42023488611). RESULTS: Of the 1766 unique studies identified, 86 were selected for full-text review. Eight studies (n = 3,699) were eligible for inclusion. Studies, spanning from 1995 to 2017, primarily focused on epilepsy surgeries. The pooled proportion was 3 % (95 % CI 2 %-5 %; 95 % PI 0 %-11 %). Temporal resections indicated twofold increase of PNES comparing to either resections (OR 2.05, 95 %CI 0.81-5.19). The risk of bias assessment indicated satisfactory quality for included studies, and heterogeneity in estimates was mainly explained by publication year of studies and their rounded sample size. CONCLUSIONS: Given the estimations, there is expected impact of intracranial procedures on functional seizures epidemiology. Further efforts need to understand the contribution of brain resections to PNES incidence.

Physician perceptions of medically unexplained symptoms in adolescent patients presenting to the emergency department.

INTRODUCTION: Adolescents presenting with medically unexplained symptoms (MUS) in non-mental healthcare settings, particularly Emergency Departments (EDs), pose diagnostic challenges necessitating a comprehensive bio-psycho-social approach. Amid the youth mental health crisis, recognising psychological distress is imperative. This study delved into physicians' perceptions and diagnostic tendencies regarding such cases, exploring the potential overshadowing of psychosomatic presentations by medicalized diagnoses in EDs. METHODS: Our study involved 74 physicians, representing 82% of eligible respondents in the Paediatric Emergency Medicine Department, and was conducted using an online questionnaire examining perceptions of case scenarios with psychosomatic presentations. RESULTS: Results disclosed a prevalent inclination toward medical diagnoses, with less than 10% of physicians considering psychosomatic conditions in specific scenarios. Interestingly, psychosomatic diagnoses were more probable for symptoms like headaches, shortness of breath, and chest pain. The study uncovered a possible bias among physicians towards medical diagnoses in EDs for adolescents with MUS, possibly stemming from physicians' focus on physical care, diagnostic uncertainties, cognitive biases, and concerns about stigmatisation. CONCLUSION: Adolescents with MUS seeking assistance in non-mental health settings may encounter delayed mental health diagnoses and interventions. Psychosomatic symptoms could signify stressors or underlying mental health disorders. Recognising psychosocial distress early on is crucial for optimal mental health outcomes. Consequently, the study advocates for a paradigm shift towards a holistic bio-psychosocial approach in both medical education and practice.

Efficacy of verbal suggestion, verbal suggestion with a tuning fork, and verbal suggestion with a cotton swab for inducing the paroxysmal event during video-EEG recording in children with suspected psychogenic nonepileptic seizures.

INTRODUCTION: Video-electroencephalogram (EEG) with suggestion is widely considered the gold standard for diagnosing psychogenic nonepileptic seizures (PNES). However, ethical concerns and uncertainties persist regarding the most minimally invasive and least deceptive suggestion approach. MATERIALS AND METHODS: In an open-label randomized controlled trial, we evaluated the effectiveness of three suggestion methods (verbal suggestion, verbal suggestion with a tuning fork, and verbal suggestion with a cotton swab) during short-term video-EEG (STVEEG) recordings to induce PNES in children aged 5-18 years. If the paroxysmal event couldn't be elicited with the assigned method, alternative techniques were employed. RESULTS: Out of 97 initially screened children, 75 were enrolled, with 25 in each group. The efficacy of all three suggestion methods was comparable in reproducing paroxysmal events (success rate of 16/25, 17/25 and 17/25 in verbal suggestion only, verbal suggestion with tuning fork and sterile cotton swab group respectively, p = 0.83) and the time required for induction (median of 2, 3 and 3 min respectively, p = 0.21). After trying alternative methods, 20 %, 12 %, and 12 % more patients in these three groups, respectively, were able to reproduce the paroxysmal event, with the differences not reaching statistical significance (p = 0.74). The assigned induction method or the success/failure of event reproduction did not significantly impact clinical outcomes at 12 weeks, and none of the patients in whom PNES could not be reproduced during STVEEG were later found to have an organic cause. Only the presence of psychiatric comorbidity independently predicted successful event reproduction during STVEEG, with statistical significance even after adjusting for other variables (p = 0.03). CONCLUSION: The efficacy of verbal suggestion alone in inducing paroxysmal nonepileptic seizures is on par with using a tuning fork or cotton swab in conjunction with verbal suggestion during STVEEG.

Four-year follow-up of psychiatric and psychosomatic profile in patients with Inflammatory Bowel Disease (IBD).

Psychological characterization of patients affected by Inflammatory Bowel Disease (IBD) focuses on comorbidity with psychiatric disorders, somatization or alexithymia. Whereas IBD patients had higher risk of stable anxiety and depression for many years after the diagnosis of the disease, there is a lack of studies reporting a comprehensive psychosomatic assessment addressing factors of disease vulnerability, also in the long-term. The objective of this investigation is to fill this gap in the current literature. The aims were thus to assess: a) changes between baseline and a 4-year follow-up in psychiatric diagnoses (SCID), psychosomatic syndromes (DCPR), psychological well-being (PWB-I), lifestyle, gastrointestinal symptoms related to IBD and Irritable Bowel Syndrome (IBS)-like symptoms b) stability of psychiatric and psychosomatic syndromes at 4-year follow-up. A total of 111 IBD outpatients were enrolled; 59.5% of them participated at the follow-up. A comprehensive assessment, including both interviews and self-report questionnaires, was provided at baseline and follow-up. Results showed increased psychiatric diagnoses, physical activity, consumption of vegetables and IBS-like symptoms at follow-up. Additionally, whereas psychiatric diagnoses were no longer present and new psychopathological pictures ensued at follow-up, more than half of the sample maintained psychosomatic syndromes (particularly allostatic overload, type A behavior, demoralization) from baseline to follow-up. Long-term presence/persistence of such psychosocial burden indicates the need for integrating a comprehensive psychosomatic evaluation beyond traditional psychiatric nosography in IBD patients. Moreover, since psychosomatic syndromes represent vulnerability factors of diseases, further studies should target subgroups of patients presenting with persistent psychosomatic syndromes and worse course of the disease.

A patient with Fibromyalgia and Chronic Recurrent Multifocal Osteomyelitis: the importance of psychosomatic assessment.

Background: Many patients affected by FM present different comorbidities, but to date no case of FM in patients with CRMO has been reported in literature. Several studies show the importance of psychosomatic assessment in FM, but only one reported the presence of allostatic overload. Case presentation: In April 2022, a 21-year-old female patient, a third-year medical student, came to our clinic to be assessed and treated for FM. She presents with a diagnosis of CRMO made in 2014 and a diagnosis of FM made in 2019. Results: At the psychiatric evaluation she presented symptoms of anxiety, depression, insomnia and reported widespread pain with the presence of almost daily headaches. From the psychosomatic point of view using DCPR-revised she presented diagnostic criteria for allostatic overload, related to study and periodic flare-ups of painful symptoms due to CRMO, persistent somatization, with musculoskeletal and gastroenterological symptoms, demoralization and type A behaviour. Conclusion: This case shows how useful a psychosomatic assessment of the patient can be for offering insights into what stressors at the origin of allostatic overload may be present in different FM patients.

Design and validation of a diagnostic suspicion checklist to differentiate epileptic from psychogenic nonepileptic seizures (PNES-DSC).

OBJECTIVE: Psychogenic non-epileptic seizures (PNES) are complex clinical manifestations and misdiagnosis as status epilepticus remains high, entailing deleterious consequences for patients. Video-electroencephalography (vEEG) remains the gold-standard method for diagnosing PNES. However, time and economic constraints limit access to vEEG, and clinicians lack fast and reliable screening tools to assist in the differential diagnosis with epileptic seizures (ES). This study aimed to design and validate the PNES-DSC, a clinically based PNES diagnostic suspicion checklist with adequate sensitivity (Se) and specificity (Sp) to discriminate PNES from ES. METHODS: A cross-sectional study with 125 patients (n = 104 drug-resistant epilepsy; n = 21 PNES) admitted for a vEEG protocolised study of seizures. A preliminary PNES-DSC (16-item) was designed and used by expert raters blinded to the definitive diagnosis to evaluate the seizure video recordings for each patient. Cohen's kappa coefficient, leave-one-out cross-validation (LOOCV) and balance accuracy (BAC) comprised the main validation analysis. RESULTS: The final PNES-DSC is a 6-item checklist that requires only two to be present to confirm the suspicion of PNES. The LOOCV showed 71.4% BAC (Se = 45.2%; Sp = 97.6%) when the expert rater watched one seizure video recording and 83.4% BAC (Se = 69.6%; Sp = 97.2%) when the expert rater watched two seizure video recordings. CONCLUSION: The PNES-DSC is a straightforward checklist with adequate psychometric properties. With an integrative approach and appropriate patient history, the PNES-DSC can assist clinicians in expediting the final diagnosis of PNES when vEEG is limited. The PNES-DSC can also be used in the absence of patients, allowing clinicians to assess seizure recordings from smartphones.

Do we intervene less and slower in the epilepsy monitoring unit for psychogenic seizures?

PURPOSE: Individuals with psychogenic non-epileptic seizures (PNES) can be stigmatized in healthcare settings. We aimed to compare intervention rate (IR), intervention time (IT), and adverse event (AE) rate between PNES and epileptic seizures (ES) in the epilepsy monitoring unit (EMU). METHODS: We used a prospective database of consecutive admissions to our centre's EMU between August 2021 and September 2022. We excluded purely electric seizures and vague, minor spells with no EEG correlate. We therefore only included electroclinical seizures and PNES. We compared the IR, IT, and AE rate between PNES and ES, as diagnosed by an epileptologist during EEG monitoring. We performed the same comparisons between spells occurring in people admitted with a high vs low suspicion of PNES (HSP vs LSP). We also verified if ITs became longer with repeated PNES. RESULTS: We analyzed 586 spells: 43 PNES vs 543 ES, or 133 HSP vs 453 LSP. Our univariate analyses showed that IR was higher for PNES than for ES (93 % vs 61 %, p <.001) but that IT and AE rate were similar across groups. This higher IR was only apparent outside weekday daytime hours, when EEG technologists were not present. HSP did not differ from LSP in terms of IR, IT, and AE rate. As PNES accumulated in individual patients, IT tended to be longer (Spearman's correlation = 0.42; p =.012). SIGNIFICANCE: Our EMU staff did not intervene less or slower for PNES. Rather, IR was higher for PNES than for ES, but IT tended to be longer with repeat PNES.

Which psychogenic nonepileptic seizure (PNES) patients are more likely to be treated with anti-seizure medications?

BACKGROUND: The average time for psychogenic nonepileptic seizures (PNES) diagnosis is about 7.5 years. Many patients receive inadequate treatment and sometimes even life-threatening treatments such as tracheal intubation during this time. PURPOSE: To determine the risk factors for misdiagnosis of PNES as Epilepsy. METHODS: The medical records of patients who underwent video-electroencephalogram (EEG) monitoring were reviewed retrospectively. Patients who had PNES without epileptic seizures (ES) were included in this study. Baseline personal and monitoring characteristics were collected. The patients were then divided into two groups based on their therapeutic status. Patients in the treatment group were again divided into two groups based on the number of anti-seizure medications (ASM) they were treated with. RESULTS: Fifty-seven patients diagnosed with PNES were included in this study. Thirty-seven patients were under treatment, and 20 patients were not under treatment at the time of monitoring. Motor seizures, abnormal interictal EEG patterns, and pathological brain imaging findings were more frequent among patients in the treatment group (p<0.05). Patients with motor seizures were more likely to be treated with multiple ASM than patients with only dialeptic nonmotor seizures (p<0.05). Lastly, patients in the treatment group were monitored longer and had fewer seizures during monitoring (p<0.05). CONCLUSION: PNES patients with abnormal EEG patterns and pathological brain imaging findings are more likely to be treated with ASM. The pure dialeptic nature of seizures is less likely to be misdiagnosed as ES. In addition, patients with such seizures are less likely to be treated with multiple treatment lines.

Maladaptive personality traits in patients with epilepsy and psychogenic non-epileptic seizures.

OBJECTIVE: We aimed to evaluate the sociodemographic, clinical, and psychological characteristics associated with psychogenic non-epileptic seizures (PNES) in patients with epilepsy, with particular emphasis on the personality profile assessed from a dimensional perspective. METHODS: The cohort study included 77 consecutive inpatients with active epilepsy aged 36-55 years; 52 (67.5%) were female. The presence of PNES was confirmed by video-EEG monitoring. All patients underwent the Mini-International Neuropsychiatric Interview to diagnose psychiatric disorders. All participants completed the Neurological Disorders Depression Inventory in Epilepsy, the Epilepsy Anxiety Survey Instrument - brief version, and the Personality Inventory for DSM-5 and ICD-11 Brief Form Plus Modified. Chi-square and Fisher's exact tests were used to compare categorical variables, and the Brunner-Munzel test was used for quantitative variables. RESULTS: Twenty-four patients (31.2%) had both epilepsy and PNES. There were no significant differences in social, demographic or clinical characteristics, psychiatric diagnoses or depression severity. Compared to patients with epilepsy alone, patients with epilepsy and PNES had higher anxiety scores and more pronounced maladaptive personality traits such as disinhibition and psychoticism. SIGNIFICANCE: The main novelty of our study is that using the recently proposed dimensional approach to personality disorders and an appropriate instrument we assessed all personality domains listed in two of the most widely used classifications of mental disorders (DSM-5 and ICD-11) in PWE with and without PNES. To our knowledge, this is the first study to demonstrate the association of the maladaptive traits of psychoticism and disinhibition with the development of PNES in PWE.

Long COVID: a new word for naming fibromyalgia?

Long COVID is the name given to a syndrome comprising a wide variety of symptoms persisting more than 3 months after acute benign COVID-19, with a prevalence ranging from 10 to 80%. Symptoms are very close to fibromyalgia. Several studies showed that long COVID prevalence was much higher after the first wave of the pandemics and was associated to the fact of thinking having had COVID rather than having had really COVID. Thus, it was the stress of the first wave with the lockdown and not the consequences of the infection that probably induced this high frequency of long COVID. Numbers of studies tried to find objective biological abnormalities for explaining long COVID but none of them could be replicated and convincing. The concept of long COVID seems to be a repetition of history of medicine, in which the doctors and the society gave different names to fibromyalgia with the objective of trying to highlight the fact that fibromyalgia could be a somatic disease with a well understood pathophysiology and to avoid to focus on the psychosomatic aspects of the disease. In conclusion, "to name is to soothe" as said by Roland Barthes. However, "Naming things wrongly adds to the world's unhappiness" was saying Albert Camus. Thus, the term of long COVID, which suggests viral persistence of impaired immune response to the virus, is unappropriated and should be replaced by fibromyalgia-like post-COVID syndrome. Research on the psychosomatic and somatic mechanisms involved in these fibromyalgia-like post-viral syndromes must be encouraged.

[Psychosomatic aspects in otorhinolaryngology-historical milestones]. / Psychosomatische Aspekte in der HNO-Heilkunde ­ historische Meilensteine.

BACKGROUND: This investigation examined the development of psychosomatics in the field of otolaryngology in Germany using the examples of psychogenic deafness and chronic tinnitus by means of literature research. The focus of the study was on the period 1948-2022. METHODS: A literature search was carried out in the PubMed database from 1948 and antiquarian ENT textbooks were evaluated. The search terms used were "ENT and psychosomatics," "tinnitus," "retraining therapy," "analytical psychology," "behavioral therapy," and "sensory systems." RESULTS: Psychosomatic phenomena were mentioned in the treatment of nasal diseases and ear ailments in writings of Byzantine and medieval medicine. Even older are references to tinnitus in ancient Egyptian and Indian scripts. From the nineteenth to the mid-twentieth century, psychological abnormalities in ENT symptoms were assigned to the term hysteria. From the middle of the twentieth century, a paradigm shift in the assessment of psychosomatic disorders in otolaryngology became apparent. In the 1950s, a broad psychosomatic discussion was opened in individual lectures and book contributions on mental abnormalities in ENT diseases. With the implementation of the Psychosomatics Working Group of the German Society of Otorhinolaryngology, Head and Neck Surgery, psychosomatics in the field of ENT received the framework for scientific and clinical activity at the turn of the millennium. Psychosomatics is scientifically represented and part of the continuing education regulations for otolaryngology in Germany and at European level. It shows high standards in research, qualification of otolaryngologists, and patient care. CONCLUSION: As of 2022, psychosomatics in otolaryngology has been steadily developing for over 70 years. The standards achieved are to be further expanded and research on cognition, affectivity, and sensory analogies intensified.

Pediatric psychogenic non-epileptic seizures: A retrospective observational cohort study at a quaternary center.

BACKGROUND: Psychogenic non-epileptic seizures (PNES) represent a common functional disorder in the pediatric population. We aimed to characterize pediatric PNES by describing their clinical characteristics, PNES semiologies, and healthcare pathway towards and after diagnosis. MATERIAL AND METHODS: This was a retrospective, observational chart review of pediatric patients aged 6 to 18 years admitted between December 2020 and December 2021 for spell classification or suspected PNES. Psychogenic non-epileptic seizure diagnosis was made by the capture of a typical event on video electroencephalogram (vEEG). We used descriptive statistics to summarize demographic and clinical characteristics. RESULTS: We included 26 patients (18 females, 69.2%) with a mean age (SD) of 13.9 (2.5) years. Pre-morbid neurologic and psychiatric conditions included: epilepsy (23.1%), migraine (46.2%), mild traumatic brain injury (26.9%), anxiety (57.7%), ADHD (34.6%), and depression (30.8%). Six patients (23.1%) had a prior diagnosis of PNES. 14 patients (53.8%) presented with convulsive, and 6 (23.1%) each with non-convulsive and mixed PNES. Patients were seen by a range of providers prior to diagnosis including ED providers (50%), neurologists (53.8%), pediatricians (34.6%), and psychology/psychiatry (11.5%). Emergency department evaluation occurred for 13 patients (50%) on 15 occasions, and six (23.1%) were admitted to the hospital. The median (p25-p75) time from PNES onset to presentation and diagnosis at our institution was 3.5 (1.5-6.2) and 4.1 (3-7) months, respectively. A total of 33 events from the 26 patients were captured on vEEG. The most frequent semiologies in our cohort were rhythmic motor (27.3%) followed by equal frequency (18.2%) of complex motor and dialeptic. Eighteen patients (69.2%) were followed after the PNES diagnosis, for a median (p25-p75) of 17.3 months (6.3-21) with variable outcome. CONCLUSION: Pediatric PNES has female predominance and often presents with comorbid psychosocial stressors and psychiatric conditions. High clinical suspicion and early recognition are crucial to decrease healthcare utilization and establish timely diagnosis and treatment.

Illness Denial in Medical Disorders: A Systematic Review.

INTRODUCTION: Illness denial pertains to medical patients who do not acknowledge the presence or severity of their disease or the need of treatment. OBJECTIVE: This systematic review was performed to clarify the clinical role and manifestations of illness denial, its impact on health attitudes and behavior, as well as on short- and long-term outcomes in patients with medical disorders. METHODS: The systematic search according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines was conducted on PubMed, Scopus, and Web of Science. RESULTS: The initial search yielded a total of 14,098 articles; 176 studies met the criteria for inclusion. Illness denial appeared to be a relatively common condition affecting a wide spectrum of health attitudes and behavior. In some cases, it may help a person cope with various stages of illness and treatment. In other situations, it may determine delay in seeking treatment, impaired adherence, and reduced self-management, leading to adverse outcomes. The Diagnostic Criteria for Psychosomatic Research (DCPR) were found to set a useful severity threshold for the condition. An important clinical distinction can also be made based on the DCPR for illness denial, which require the assessment of whether the patient has been provided with an adequate appraisal of the medical situation. CONCLUSIONS: This systematic review indicates that patients with medical disorders experience and express illness denial in many forms and with varying degrees of severity. The findings suggest the need for a multidimensional assessment and provide challenging insights into the management of medical disorders.

Psychosocial determinants of healthcare use costs in kidney transplant recipients.

Introduction: Psychosocial factors frequently occur in kidney transplant recipients (KTRs), leading to behavioral alterations and reduced therapeutic adherence. However, the burden of psychosocial disorders on costs for KTRs is unknown. The aim of the study is to identify predictors of healthcare costs due to hospital admissions and emergency department access in KTRs. Methods: This is a longitudinal observational study conducted on KTRs aged >18 years, excluding patients with an insufficient level of autonomy and cognitive disorder. KTRs underwent psychosocial assessment via two interviews, namely the Mini-International Neuropsychiatric Interview 6.0 (MINI 6.0) and the Diagnostic Criteria for Psychosomatic Research Interview (DCPR) and via the Edmonton Symptom Assessment System Revised (ESAS-R) scale, a self-administrated questionnaire. Sociodemographic data and healthcare costs for hospital admissions and emergency department access were collected in the 2016-2021 period. Psychosocial determinants were as follows: (1) ESAS-R psychological and physical score; (2) symptomatic clusters determined by DCPR (illness behavior cluster, somatization cluster, and personological cluster); and (3) ICD diagnosis of adjustment disorder, anxiety disorder, and mood disorder. A multivariate regression model was used to test the association between psychosocial determinants and total healthcare costs. Results: A total of 134 KTRs were enrolled, of whom 90 (67%) were men with a mean age of 56 years. A preliminary analysis of healthcare costs highlighted that higher healthcare costs are correlated with worse outcomes and death (p < 0.001). Somatization clusters (p = 0.020) and mood disorder (p < 0.001) were positively associated with costs due to total healthcare costs. Conclusions: This study showed somatization and mood disorders could predict costs for hospital admissions and emergency department access and be possible risk factors for poor outcomes, including death, in KTRs.

[Psychosomatic medicine: old resources and new technologies]. / Psikhosomaticheskaya meditsina: starye resursy i novye tekhnologii.

Two primary research directions closely coexist in psychosomatic medicine. One is the most traditional, associated with an assessment of the psychological aspects of the connection, interconnection and mutual impact of mental and somatic pathology. The second, based on the rapid development of biological medicine in the last decade, studies causal associations and looks for shared mechanisms. In our review, we consider the previous main stages in the psychosomatic medicine and the prospective approaches to its further study. Evaluation of the etiopathogenesis of the entire set of mental and somatic symptoms in their interaction and dynamics can help identify individual subpopulations of patients with shared pathobiochemical and neurophysiological disorders. The recent interpretation of the biopsychosocial model is mainly related to the etiology and pathogenesis of mental disorders and also provides a good perspective for research on these issues. Today, there are sufficient opportunities to study all three domains of the model. Productive study of the biological, personal and social domains is also possible on the base of evidence-based design using modern research technologies.

[To the problem of somatic-hypochondriac paranoia]. / K probleme somaticheskoi-ipokhondricheskoi paranoii.

OBJECTIVE: To unite within the framework of a single clinical entity (based on the model of hypochondriacal paranoia) phenomena of the somatopsychotic and hypochondriacal range, which, in accordance with modern systematics, are classified as various categories of psychosomatic, affective disorders and personality disorders. MATERIAL AND METHODS: The sample for analysis consisted of 29 patients (with the diagnosis of delusional disorder (ICD-10; F22.0 in ICD-10), 10 men (34.5%) and 19 women (64.5%), the average age was 42.9±19.9 years; men - 10 nab. (34.5%), women - 19 nab. (64.5%). The average duration of the disease iswas 9.4±8.5 years. The psychopathological method was used as the main one. RESULTS: The article forms an alternative concept of somatic paranoia based on the model of hypochondriacal paranoia. The fundamental difference between the construct of somatic paranoia is an obligate connection between somatopsychic and ideational disorders. Somatopsychic (coenesthesiopathic) symptoms do not exist as an independent (equivalent to the structure of somatic clinical syndromes) dimensions and are formed exclusively with the participation of ideational phenomena. CONCLUSION: In accordance with the presented concept, coenesthesiopathic symptoms within the framework of somatic paranoia act as a somatic equivalent of delusional disorders.

[Nosogenic psychosomatic disorders in patients with skin diseases]. / Nozogennye psikhosomaticheskie rasstroistva u patsientov s kozhnymi zabolevaniyami.

OBJECTIVE: Development of a clinical typology of nosogenic psychosomatic disorders in patients with skin diseases. MATERIAL AND METHODS: The study was carried out in the interclinical psychosomatic department of the Clinical Center and the Clinic of Skin and Venereal Diseases named after. V.A. Rakhmanov Sechenov University in 2007 to 2022. Nine hundred and forty-two patients (253 males, 689 females, average age 37.3±12.4 years) with nosogenic psychosomatic disorders in chronic dermatoses, including ichen planus (n=143), psoriasis (n=137), atopic dermatitis (n=132), acne (n=118), rosacea (n=115), eczema n=10), seborrheic dermatitis (n=88), vitiligo (n=52), pemphigus (n=48), were studied. Index of clinical symptoms (ICS); the Dermatology Quality of Life Index (DQLI); itching severity questionnaire - Behavioral rating scores (BRS); the Hospital Anxiety and Depression Scale (HADS) and statistical methods were used. RESULTS: In patients with chronic dermatoses, nosogenic psychosomatic disorders were diagnosed according to ICD-10 criteria within adaptation disorders [F43.8] (n=465; 49.3%); hypochondriacal disorder [F45.2] (n=235; 24.9%); constitutionally determined and acquired (hypochondriac development) personality disorders [F60] (n=118; 12.5%); schizotypal disorder [F21] (n=65; 6.9%); recurrent depressive disorder [F33] (n=59; 6.2%). A typological model of nosogenic disorders in dermatology has been developed: hypochondriacal nosogenies in severe clinical forms of dermatosis (pemphigus, psoriasis, lichen planus, atopic dermatitis, eczema) and dysmorphic nosogenies in objectively mild, but cosmetically significant forms of dermatosis (acne, rosacea, seborrheic dermatitis, vitiligo). When analyzing socio-demographic and psychometric indicators, significant differences were revealed between the selected groups (p<0.001). In turn, the selected groups of nosogenic disorders demonstrate significant clinical heterogeneity and include various types of nosogenies that form a unique palette of the nosogenic spectrum in the structure of an extensive psychodermatological continuum. Along with the severity of the skin process, the dominant role in the formation of the clinical picture of nosogeny, including cases of paradoxical dissociation of the quality of life with the severity of dermatosis, amplification and somatization of itching, has a premorbid personality structure and somatoperceptive accentuation of the patient, as well as the presence of a comorbid mental disorder. CONCLUSION: The typology of nosogenic psychosomatic disorders in patients with skin diseases requires consideration of both the psychopathological structure of the disorders under discussion and the severity/clinical features of the skin process.

Reliability and validity of the brief psychosomatic symptom scale (BPSS) in patients from general hospitals.

OBJECTIVES: To verify the Brief Psychosomatic Symptom Scale (BPSS) among patients with psychosomatic-related disorders in general hospitals and determine the threshold of BPSS. METHODS: The BPSS is a shortened 10-item version of the psychosomatic symptoms scale (PSSS). Data from 483 patients and 388 healthy controls were included for psychometric analyses. Internal consistency, construct validity, and factorial validity were verified. The threshold of BPSS in distinguishing psychosomatic patients from healthy controls were determined using receiver operating characteristic (ROC) curve analysis. The ROC curve of the BPSS was compared with that of the PSSS and patient health questionnaire-15 (PHQ-15) by using Venkatraman's method with 2000 times Monte-Carlo simulations. RESULTS: The reliability of the BPSS was good with Cronbach's α of 0.831. BPSS was significantly correlated with PSSS (r = 0.886, P < 0.001), PHQ-15 (r = 0.752, P < 0.001), PHQ-9 (r = 0.757, P < 0.001) and GAD-7 (r = 0.715, P < 0.001), which indicated good construct validity. ROC analyses demonstrated that the AUC of the BPSS was comparable with that of PSSS. The gender-specific threshold of BPSS was determined as ≥8 in males and ≥ 9 in females. CONCLUSIONS: The BPSS is a brief and validated instrument for screening common psychosomatic symptoms.
