This review explores the workings of the legal process in posttraumatic headache (PTH) claims by discussing representative court cases, the approaches taken by both plaintiff and defense attorneys in evaluating a client with PTH, and the role of the expert witness. This discussion also examines the question of whether or not litigation prolongs the symptoms of PTH and concussion, looking at the issues of malingering and the psychological effect of litigation. ⋯ Litigation prolongs recovery of PTH, primarily not from malingering but rather due to the psychological mindset of the plaintiff as created by the litigation process. Just as the medical community struggles with PTH diagnosis, mechanism, and treatment, the legal system grapples with identifying valid claims for PTH. Psychological support is an important component for PTH recovery to more effectively deal with the psychological impact of litigation and the concept of perceived injustice.

ReviewPain Management in Painful Psoriasis and Psoriatic Arthropathy: Challenging and Intricately Intertwined Issues Involving Several Systems.
Psoriasis and psoriatic arthropathy are inflammatory autoimmune conditions that can lead to profound emotional distress, social stigmatization, isolation, disfigurement, pain, disability, unemployment, and decreased quality of life. Thus, this disease has immense psychological, social, and economic implications as the pain experienced is closely associated with the primary disease burden. This review focuses on discussing the primary disease burden of psoriasis and psoriatic arthropathy, as well as management of different types of pain in these patients. ⋯ Pain affects over 40% of patients with psoriasis, ranging from neuropathic to nociceptive. Treatment of pain largely focuses on treating the underlying disease with mild topical steroids and non-steroidal medications including vitamin D analogs followed by systemic immunomodulatory agents for more severe disease. Interventional options such as corticosteroid injections are available for select cases (conditional recommendation). Psoriasis and psoriatic arthropathy have been associated with underreporting and resultant undertreatment of pain. Pain control in these conditions is complex and requires a multidisciplinary approach. More research and guidelines are needed in the areas of reporting of psoriatic disease, associated pain, psoriatic nociception, and optimal clinical management.

ReviewRecent Advances of Magnetic Resonance Neuroimaging in Trigeminal Neuralgia.
Trigeminal neuralgia (TN) is a disease of unclear pathogenesis. It has a low incidence and is not fatal, but it can cause afflicted patients' depression or suicide. In the past, neurovascular compression was considered to be the main cause of TN, but recent studies have found that neurovascular contact is also common in asymptomatic patients and the asymptomatic side in symptomatic patients. ⋯ Thus, the study of the peripheral branches of the trigeminal nerve is necessary to understand the etiology of TN. With the development of imaging technology and the emergence of various imaging modalities, it is possible to study the etiology of TN and the pathological changes of related structures by magnetic resonance neuroimaging. This article reviews the recent advances in magnetic resonance neuroimaging of the trigeminal nerve.

Chronic pain is a widespread public and physical health crisis, as it is one of the most common reasons adults seek medical care and accounts for the largest medical reason for disability in the USA (Glombiewski et al., J Consult Clin Psychol. 86(6):533-545, 2018; Schemer et al., Eur J Pain. 23(3):526-538, 2019). Chronic pain is associated with decreased functional status, opioid dependence and substance abuse disorders, mental health crises, and overall lower perceived quality of life (Korff et al., J Pain. 17(10):1068-1080, 2016). For example, the leading cause of chronic pain and the leading cause of long-term disability is low back pain (LBP) (Bjorck-van Dijken et al. J Rehabil Med. 40:864-9, 2008). Evidence suggests that persistent low back pain (pLBP) is a multidimensional biopsychosocial problem with various contributing factors (Cherkin et al., JAMA. 315(12):1240-1249, 2016). Emotional distress, pain-related fear, and protective movement behaviors are all unhelpful lifestyle factors that previously were more likely to go unaddressed when assessing and treating patient discomfort (Pincus et al., Spine. 38:2118-23, 2013). Those that are not properly assisted with these psychosocial issues are often unlikely to benefit from treatment in the primary care setting and thus are referred to multidisciplinary pain rehabilitation physicians. This itself increases healthcare costs, and treatments can be invasive and have risks of their own. Therefore, less expensive and more accessible management strategies targeting these psychosocial issues should be started to facilitate improvement early. As a biopsychosocial disorder, chronic pain is influenced by a range of factors including lifestyle, mental health status, familial culture, and socioeconomic status. Physicians have moved toward multi-modal pain approaches in order to combat this public health dilemma, ranging from medications with several different mechanisms of action, lifestyle changes, procedural pain control, and psychological interventions (Fashler et al., Pain Res Manag. 2016:5960987, 2016). Part of the rehabilitation process now more and more commonly includes cognitive behavioral and cognitive functional therapy. Cognitive functional therapy (CFT) and cognitive behavioral therapy (CBT) are both multidimensional psychological approaches to combat the mental portion of difficult pain control. While these therapies are quite different in their approach, they lend to the idea that chronic pain can and should be targeted using coping mechanisms, helping patients understand the pathophysiological process of pain, and altering behavior. ⋯ CFT differs from CBT functionally, as instead of improving managing/coping mechanisms of pain control from a solely mental approach, CFT directly points out maladaptive behaviors and actively challenges the patient to change them in a cognitively integrated, progressive overloading functional manner (Bjorck-van Dijken et al. J Rehabil Med. 40:864-9, 2008). This allows CFT to be targeted to each individual patient, with the goal of personalized reconceptualization of the pain response. The end goal is to overcome the barriers that prevent functional status improvement, a healthy lifestyle, and reaching their personal goals. Chronic pain is a major public health issue. Cognitive functional therapy (CFT) and cognitive behavioral therapy (CBT) are both multidimensional psychological approaches to combat the mental portion of difficult pain control. While these therapies are quite different in their approach, they lend to the idea that chronic pain can and should be targeted using coping mechanisms, helping patients understand the pathophysiological process of pain, and altering behavior.

Though first bite syndrome is well known in surgical settings, it is not commonly included in the differential for sharp paroxysmal facial pain in the neurology literature. This paper will highlight the clinical features and relevant anatomy of first bite syndrome, with the goal of helping clinicians differentiate this from other similar facial pain disorders. ⋯ First bite syndrome is severe sharp or cramping pain in the parotid region occurring with the first bite of each meal and improving with subsequent bites. Pathophysiology has been attributed to imbalanced sympathetic/parasympathetic innervation of the parotid gland. This is seen most typically in the post-surgical setting following surgery in the parotid or parapharyngeal region, but neoplastic etiologies have also been reported. It is common for patients to present with concurrent great auricular neuropathy and/or Horner's syndrome. Evidence regarding treatment is limited to case reports/series, however, botulinum toxin injections and neuropathic medicines have been helpful in select cases. It is critical for clinicians to be able to differentiate first bite syndrome from other paroxysmal facial pain. To help with this, we have proposed diagnostic criteria for clinical assessment. Patients often improve gradually over time, but symptomatic treatment with botulinum toxin or neuropathic medicine may be required.
