Feasibility of the interdisciplinary multimodal assessment-The team perspective

Secondary preventive outpatient diagnostic services for patients with pain and risk factors for chronification have not yet been sufficiently established. In the PAIN2020 project (Innovation Fund, 01NVF17049) an outpatient interdisciplinary multimodal assessment (IMA) was introduced for the first time early in the course of the disease. For the implementation of the IMA procedures for team cooperation and decision criteria were developed, which were implemented by ateam of medical, physiotherapeutic and psychological therapists. These procedures and decision criteria are to be discussed against the background of clinical experience and examined with respect to their feasibility (qualitative). In PAIN2020 aworkshop on IMA was held in September 2021 to jointly reflect on the findings and experiences gained in the process so far through monitoring and structuring documentation in the implementation with staff or teams of PAIN2020 centers on the feasibility of implementing astructured interdisciplinary multimodal assessment. In three work phases, occupational group-specific and cross-occupational group topics were addressed. In the decision-making processes of the occupational groups, in addition to profession-specific focal points within the framework of the assessment of findings (somatic, functional or psychosocial core criteria), overarching core criteria within the professions as well as complementary patient-related aspects are evident, which are included in the integrative team process. With respect to team collaboration, the implementation of the team meeting and the final discussion can be used to identify structural and process parameters that promote or inhibit implementation, which are also accompanied by interactional factors. For the implementation of the IMA, there were (1)adaptations of the IMA, which is currently implemented as A‑IMA in the selective agreement with BARMER and (2)new dimensions or task fields and ideas for evidence-based concepts for the content design of integrative diagnostics as well as for the feedback of the results to the patients, which should be discussed in the future.

Clinical markers of post-Chikungunya chronic inflammatory joint disease: A Brazilian cohort.

Chikungunya-fever (CHIKF) remains a public health major issue. It is clinically divided into three phases: acute, post-acute and chronic. Chronic cases correspond to 25-40% individuals and, though most of them are characterized by long-lasting arthralgia alone, many of them exhibit persistent or recurrent inflammatory signs that define post-Chikungunya chronic inflammatory joint disease (pCHIKV-CIJD). We aimed to identify early clinical markers of evolution to pCHIKV-CIJD during acute and post-acute phases. We studied a prospective cohort of CHIKF-confirmed volunteers with longitudinal clinical data collection from symptoms onset up to 90 days, including a 21-day visit (D21). Of 169 patients with CHIKF, 86 (50.9%) completed the follow-up, from whom 39 met clinical criteria for pCHIKV-CIJD (45.3%). The relative risk of chronification was higher in women compared to men (RR = 1.52; 95% CI = 1.15-1.99; FDR = 0.03). None of the symptoms or signs presented at D0 behaved as an early predictor of pCHIKV-CIJD, while being symptomatic at D21 was a risk factor for chronification (RR = 1.31; 95% CI = 1.09-1.55; FDR = 0.03). Significance was also observed for joint pain (RR = 1.35; 95% CI = 1.12-1.61; FDR = 0.02), reported edema (RR = 3.61; 95% CI = 1.44-9.06; FDR = 0.03), reported hand and/or feet small joints edema (RR = 4.22; 95% CI = 1.51-11.78; FDR = 0.02), and peri-articular edema observed during physical examination (RR = 2.89; 95% CI = 1.58-5.28; FDR = 0.002). Furthermore, patients with no findings in physical examination at D21 were at lower risk of chronic evolution (RR = 0.41, 95% CI = 0.24-0.70, FDR = 0.01). Twenty-nine pCHIKV-CIJD patients had abnormal articular ultrasonography (90.6% of the examined). The most common findings were synovitis (65.5%) and joint effusion (58.6%). This cohort has provided important insights into the prognostic evaluation of CHIKF. Symptomatic sub-acute disease is a relevant predictor of evolution to chronic arthritis with synovitis, drawing attention to joint pain, edema, multiple articular involvement including small hand and feet joints as risk factors for chronification beyond three months, especially in women. Future studies are needed to accomplish the identification of accurate and early biomarkers of poor clinical prognosis, which would allow better understanding of the disease's evolution and improve patients' management, modifying CHIKF burden on global public health.

Effect on healing rates of wounds treated with direct cold atmospheric plasma: a case series.

The response of different critical acute and hard-to-heal wounds to an innovative wound care modality-direct application of cold atmospheric plasma (CAP)-was investigated in this clinical case series. Over an observation period of two years, acute wounds with at least one risk factor for chronification, as well as hard-to-heal wounds were treated for 180 seconds three times per week with CAP. CAP treatment was additional to standard wound care. Photographs were taken for wound documentation. The wound sizes before the first CAP treatment, after four weeks, after 12 weeks and at wound closure/end of observation time were determined using image processing software, and analysed longitudinally for the development of wound size. A total of 27 wounds (19 hard-to-heal and eight acute wounds) with a mean wound area of 15cm2 and a mean wound age of 49 months were treated with CAP and analysed. All (100%) of the acute wounds and 68% of the hard-to-heal wounds healed after an average treatment duration of 14.2 weeks. At the end of the observation period, 21% of hard-to-heal wounds were not yet closed but were reduced in size by >80%. In 11% of the hard-to-heal wounds (n=2) therapy failed. The results suggested a beneficial effect of additional CAP therapy on wound healing.

Vertebral artery hypoplasia and chronic migraine: is there an association or just an incidental finding?

We describe a 29-year-old woman with chronic migraine and psychiatric comorbidities that presented with new transient left-sided hemiparesis and hemi-hypoesthesia and were found to have right vertebral artery hypoplasia (VAH). We briefly review the association of VAH and migraine and the influence of psychiatric disorders and VAH as possible risk factors for chronification of episodic migraine. Despite uncertain mechanisms, VAH may be one of thecontributing factors for the chronicity of migraine.

Pain Management in Non-surgical Inpatients - Treatment Approaches and Competence for Pain Services

The number of non-surgical patients in the hospital setting with pain due to medical conditions or comorbidities and/or invasive procedures or treatments is high. Compared to perioperative pain management, the portion of patients and/or conditions that require more than an approach focused on pharmacological treatment of nociceptive pain is considerably higher. Rather, treatment often requires the differentiated use of co-analgesics, non-pharmacological treatments, physiotherapy, occupational therapy, psychological assessment and interventsions and educational approaches, ideally in the form of closely coordinated interdisciplinary treatment. The assessment and treatment of acute and especially chronic pain should follow the biopsychosocial concept of pain, especially if risk factors for chronification have been identified, if patients receive high-dose therapy with analgesics or have preexisting a chronic pain disorder.

Commentary: Novel Use of Offset Analgesia to Assess Adolescents and Adults with Treatment Resistant Endometriosis-Associated Pain.

Background and ObjectiveEndometriosis, affecting approximately 176 million adults and adolescents worldwide, is a debilitating condition in which uterine tissue grows outside the uterus. The condition costs the US economy approximately $78 billion annually in pain-related disability. By understanding the neural underpinnings of endometriosis-associated pain (EAP) and risk factors for chronification, translational research methods could lessen diagnostic delays and maximize successful pain remediation. This can be accomplished by the novel use of a known method, offset analgesia (OA), to better elucidate the neural mechanisms that may contribute to and maintain EAP. This commentary will provide justification and rationale for the use of OA in the study of EAP.ConclusionUtilizing an OA paradigm in patients with endometriosis, especially adolescents, may (1) provide insight into neural mechanisms contributing to pain maintenance, which could capture those at-risk for the transition to chronic pelvic pain, (2) provide a metric for the development of future centrally mediated treatment options for this population, and (3) elucidate the brain changes that result in resistance to treatment and pain chronification.

The role of stress and psychiatric comorbidities as targets of non-pharmacological therapeutic approaches for migraine.

This narrative review addresses the interconnections among stress, mental disorders and migraine with a specific focus on non-pharmacological interventions that may be effective in improving both migraine and the psychiatric comorbidity. Migraine is often comorbid with depression, anxiety, personality disorders, and sleep disorders. Subjective stress and stressors are common triggers for migraine attacks and are risk factors for chronification, whilst mental disorders and stress responses are closely linked in a bidirectional relation. Recent studies show that psychiatric comorbidity is associated with migraine severity, worse outcomes, increased disability and reduce quality of life. Numerous studies on non-pharmacological interventions for migraine were published and behavioural treatments included biofeedback, cognitive-behavioural therapy, relaxation training, stress management and brief psychodynamic psychotherapy. Taken together, psychological interventions proved to be effective in migraine treatment and a combination of pharmacological and psychological treatment appear to be more effective than either medication or psychotherapy alone. Non-pharmacological interventions effectiveness should be due to the improvement of migraine, stress-related vulnerability and mental disorders together and the combined treatment could prevent the chronification circuit of migraine. Well-designed long-term studies are needed to clarify comparative effectiveness of non-pharmacological techniques in the treatment and the prevention of migraine.

Risk factors for chronification in acute subdural hematoma following conservative management

Risk factors for chronification in acute subdural hematoma following conservative management

Frequency of and Risk Factors for Chronification in Traumatic Acute Subdural Hematoma following Conservative Therapy

In an aging society, traumatic head injuries, such as acute subdural hematomas (aSDHs), are increasingly common because the elderly are prone to falls and are often undergoing anticoagulation treatment. Especially in advanced age, cranial surgery such as craniotomies may put patients in further jeopardy. But if treatment is conservative, a chronic subdural hematoma (cSDH) may develop, requiring surgical evacuation. Existing studies have reported a correlation between several risk factors contributing to the frequency of chronification. To improve the prediction of the course of disease and to aid counseling patients and relatives, this study aimed to determine the frequency and the main risk factors influencing the process of chronification of an aSDH following conservative treatment. We identified patients presenting between January 2012 and September 2017 at our neurosurgical department with an aSDH. All patients treated conservatively were selected retrospectively, and the following parameters were documented: age, sex, chronification status, Glasgow Coma Scale score on admission and discharge, hematoma thickness and density, the degree of midline shift (MLS), prior anticoagulants and administration of procoagulants, thrombosis management, other coagulopathies, initial length of hospital stay, interval between discharge and readmission, and interval between initial injury and date of surgery and last follow-up. The cohort was divided into patients with complete resolution of their aSDH, and patients who needed surgery due to chronification. A total of 75 conservatively treated patients with aSDH were included. A chronification was observed in 24 cases (32%). The process of chronification takes an average of 18 days (range: 10-98 days). The following factors were significantly associated with the process of chronification: age (p = 0.001), anticoagulant medication (acetylsalicylic acid [ASA], Coumadin, and novel anticoagulants [NOACs]) before injury (p = 0.026), administration of procoagulants (p = 0.001), presence of other coagulopathies such as thrombocytopenia (p = 0.002), low hematoma density at discharge (p = 0.001), hematoma thickness on admission and discharge (p = 0.001), and the degree of MLS (p = 0.044). Chronification occurred in a third of all patients with conservatively treated aSDH, on average within 3 weeks. The probability of developing a cSDH is 0.96 times higher with every yearly increase in age, resulting in 56% chronification in patients ≥ 70 years. Hematoma thickness and impairment of the coagulation system such as anticoagulant medication (ASA, Coumadin, and NOACs) or thrombocytopenia are further risk factors for chronification.

Sleep and Migraine: Assessment and Treatment of Comorbid Sleep Disorders.

The relationship of sleep and migraine is unequivocal and familiarity with the nature and magnitude of these associations may inform clinical practice. Recent prospective, longitudinal, and time-series analysis has begun to unravel the magnitude and temporal patterns of sleep and migraine. Prospective evidence has shown that sleep variables can trigger acute migraine, precede and predict new onset headache by several years, and indeed, sleep disturbance and snoring are risk factors for chronification. The presence of a sleep disorder is associated with more frequent and severe migraine and portends a poorer headache prognosis. Interestingly, the disorders linked to migraine are quite varied, including insomnia, snoring and obstructive sleep apnea, restless legs, circadian rhythm disorders, narcolepsy, and others. Insomnia is by far the most common sleep disorder in headache patients. In fact, the majority of patients with chronic migraine presenting for treatment have insomnia. Despite a rapidly expanding literature, very few controlled treatment studies have been published to guide clinical practice. This paper focuses on clinical assessment and treatment of sleep disorders. An algorithm is presented for sleep disorders management in the migraine patient, which highlights major sleep disorders and psychiatric comorbidity. Diagnostic procedures are recommended that are conducive to clinical practice. Suggested tools include the sleep history, screening mnemonics, prediction equation, and sleep diary. New developments in treatment have produced abbreviated and cost-effective therapies for insomnia and obstructive sleep apnea that may reach a larger population. Revisions in the diagnostic manuals for sleep and headache disorders enhance recognition of sleep-related headache. Recommendations include behavioral sleep regulation, shown in recent controlled trials to decrease migraine frequency, management for sleep apnea headache, cognitive behavioral therapy (CBT) for insomnia abbreviated for the physician practice setting, sleep-related headache trigger, and others. There is no empirical evidence that sleep evaluation should delay or supersede usual headache care. Rather, sleep management is complimentary to standard headache practice.

CT-Guided Transforaminal Epidural Injections with Local Anesthetic, Steroid, and Tramadol for the Treatment of Persistent Lumbar Radicular Pain

Background: A substantial number of patients with persistent lumbar radicular pain are treated with a multimodal spectrum of conservative therapies without lasting effect. The duration of pain is certainly a risk factor for chronification. There is evidence that guided periradicular infiltrations are a valid option in the treatment of radiculopathies. Usually a combination of local anesthetic and/or corticosteroid is injected. Tramadol is being used for perioperative analgesia and has been shown to provide effective, long-lasting pain relief after epidural administration. Objective: The aim of this pilot study was to evaluate the efficacy of serial CT-guided transforaminal nerve root infiltrations with a supplement of tramadol for patients with persistent, radicular pain. Study Design: Interventional cohort study. Setting: Outpatient department for interdisciplinary pain medicine. Methods: 37 patients who had radicular leg pain for over 9 weeks received up to 3 CTguided transforaminal nerve root infiltrations at intervals of 2 weeks as long as their level of pain was over 3 on a numerical rating scale from 0 to 10. 50 mg of Tramadol were added to a combination of local anesthetic (Ropivacain, 2 mg) and corticosteroid (Triamcinolon, 40 mg). Evaluations were carried out 24 hours after the Infiltration as well as 2 weeks, 3 and 6 months after the treatment series. The intensity of their radicular pain was measured by a numerical rating scale (NRS). Pain reduction of at least 50% was defined as successful outcome. Results: In total, 65 infiltrations were carried out with pain relief in more than 90% of the patients within 24 hours and an average pain reduction of 64%. Six months post-injection 23 of 34 patients available for follow-up (67.6%) had a successful pain reduction of 84% on average. No adverse effects ascribable to the use of tramadol were noted. Limitations: Due to the lack of a control group we cannot make any statement if tramadol improves short-term pain reduction. Conclusion: Fast and lasting pain relief is the key to optimize rehabilitation for patients with radicular pain. There is a physiological rationale that the opioid receptors at the spinal level could be used to optimize the analgetic effect of guided periradicular injections. In our case series, serial CT-guided selective nerve root infiltrations with the supplement of tramadol were found to be highly effective in the treatment of persistant radiculopathies. Randomized controlled trials will be necessary to clarify the possible benefit of the supplement of an opioid. Key words: Serial, nerve root infiltration, tramadol, chronic pain, outcome.

The paradoxical effects of analgesics and the development of chronic migraine

In a subgroup of individuals episodic migraine evolves into a stage where individuals have headaches on more days than not. Among the risk factors for chronification, excessive use of analgesic medications figure prominently and reviewing this topic is the scope of this article. The issue of causality is discussed and evidence suggesting that specific medications, at critical doses, are risk factors for chronic migraine (CM) is reviewed. The concept of critical dose of exposure for different classes is presented and biological plausibility and putative mechanisms are reviewed.
