ABSTRACT Among 237 patients communicating chronic pain, associated with sensory-motor and "autonomic" displays, qualifying taxonomically for neuropathic pain, there were 16 shown through surveillance to be malingerers. When analyzed through neurological methods, their profile was characteristically atypical. There were no objective equivalents of peripheral or central processes impairing nerve impulse transmission. In absence of medical explanation, all 16 had been adjudicated, by default, the label complex regional pain syndrome (CRPS). The authors emphasize that CRPS patients may not only harbor unrecognized pathology ("lesion") of the nervous system (CRPS II), hypothetical central neuronal "dysfunction" (CRPS I), or conversion disorder, but may display a recognizable simulated illness without neuropsychiatric pathology.

    ABSTRACT: Abstract DRG is of importance in relaying painful stimulation to the higher pain centers and therefore could be a crucial target for early intervention aimed at suppressing primary afferent stimulation. Complex regional pain syndrome (CRPS) is a common pain condition with an unknown etiology. Recently added new information enriches our understanding of CRPS pathophysiology. Researches on genetics, biogenic amines, neurotransmitters, and mechanisms of pain modulation, central sensitization, and autonomic functions in CRPS revealed various abnormalities indicating that multiple factors and mechanisms are involved in the pathogenesis of CRPS. Epigenetics refers to mitotically and meiotically heritable changes in gene expression that do not affect the DNA sequence. As epigenetic modifications potentially play an important role in inflammatory cytokine metabolism, neurotransmitter responsiveness, and analgesic sensitivity, they are likely key factors in the development of chronic pain. In this dyad review series, we systematically examine the nerve injury-related changes in the neurological system and their contribution to CRPS. In this part, we first reviewed and summarized the role of neural sensitization in DRG neurons in performing function in the context of pain processing. Particular emphasis is placed on the cellular and molecular changes after nerve injury as well as different models of inflammatory and neuropathic pain. These were considered as the potential molecular bases that underlie nerve injury-associated pathogenesis of CRPS.

    ABSTRACT: Independent medical examinations (IMEs) theoretically construe a means of “independently” assessing a claimant’s physical and psychological status, as well as to determine whether treatment that has been and will potentially be provided is reasonable and necessary. IMEs may be undertaken both for the plaintiff and defense or related adversaries. In the present case, we focus on IMEs that are requested by insurers. One can query the degree to which IMEs are actually “independent.” It has been posited that one of the ways in which claims managers contribute to potential bias against claimants is through a process of selectively providing examiners with medical records, which has been described as “cherry-picking.” Despite the existence of rules and laws that are designed to prevent cherry-picking, the practice still occurs. This analysis discusses the legal as well as ethical implications of cherry-picking and its potential to cause or exacerbate psychological injury that a claimant may experience. The authors propose that psychologists as well as attorneys can advocate for their vulnerable patients/clients in cases of cherry-picking. A recent case study from the clinical practice of the first author in which he so acted is provided. We conclude with a discussion of the ethical implications of the psychologist’s intervention.

    ABSTRACT: Compared with other psychiatric disorders, diagnosis of factitious disorders is rare, with identification largely dependent on the systematic collection of relevant information, including a detailed chronology and scrutiny of the patient's medical record. Management of such disorders ideally requires a team-based approach and close involvement of the primary care doctor. As deception is a key defining component of factitious disorders, diagnosis has important implications for young children, particularly when identified in women and health-care workers. Malingering is considered to be rare in clinical practice, whereas simulation of symptoms, motivated by financial rewards, is regarded as more common in medicolegal settings. Although psychometric investigations (eg, symptom validity testing) can inform the detection of illness deception, such tests need support from converging evidence sources, including detailed interview assessments, medical notes, and relevant non-medical investigations. A key challenge in any discussion of abnormal health-care-seeking behaviour is the extent to which a person's reported symptoms are considered to be a product of choice, or psychopathology beyond volitional control, or perhaps both. Clinical skills alone are not typically sufficient for diagnosis or to detect malingering. Medical education needs to provide doctors with the conceptual, developmental, and management frameworks to understand and deal with patients whose symptoms appear to be simulated. Central to the understanding of factitious disorders and malingering are the explanatory models and beliefs used to provide meaning for both patients and doctors. Future progress in management will benefit from an increased appreciation of the contribution of non-medical factors and a greater awareness of the conceptual and clinical findings from social neuroscience, occupational health, and clinical psychology.
