- Abstract
Background: The clinical characteristics of autoimmune autonomic neuropathy are only partially defined. More than 50% of patients with high levels of ganglionic acetylcholine receptor (AChR) autoantibodies have a combination of sicca complex (marked dry eyes and dry mouth), abnormal pupillary light response, upper gastrointestinal tract symptoms, and neurogenic bladder., Objective: To compare patients with idiopathic autonomic neuropathy who were seropositive (n = 19) and seronegative (n = 87) for ganglionic AChR antibodies., Design: Retrospective review of autonomic programmatic database., Setting: Autonomic Disorders Program Project at Mayo Clinic College of Medicine, Rochester, Minn., Patients: We evaluated a cohort of 87 patients with idiopathic autonomic neuropathy who had undergone full autonomic testing and neurological evaluation and who had a complete panel of paraneoplastic and ganglionic AChR antibodies. We compared patients seropositive (n = 19) and seronegative (n = 87) for ganglionic AChR antibodies., Results: The seropositive group had a significant overrepresentation of abnormal pupillary responses (12/18 [67%] vs 12/87 [14%]; P<.001), sicca complex (9/15 [60%] vs 11/47 [23%]; P =.01), and lower gastrointestinal tract dysautonomia (16/19 [84%] vs 48/85 [56%]; P =.02). A subacute mode of onset was more common in the seropositive group (12/19 [63%] vs 23/84 [27%]; P =.004). Results of quantitative autonomic function tests differed significantly in the 2 groups only in the cardiovagal domain. Because subacute onset was overrepresented in the seropositive group, we analyzed the data separately, controlling for temporal profile (ie, the relationship between antibody status and symptoms while controlling for rate of onset). The relationships between antibody status and clinical profile (eg, presence of sicca complex, pupillary abnormalities, and lower gastrointestinal tract symptoms) generally remained significant regardless of onset rate, indicating that the associations are not due to temporal profile., Conclusions: These observations support the concept that ganglionic AChR antibodies are diagnostically and pathophysiologically important. Patients with orthostatic hypotension and prominent cholinergic dysautonomia are most likely to be seropositive for ganglionic AChR antibody.

- Abstract
We analyzed the clinical characteristics of 18 patients (13 female, 5 male) who had autoimmune autonomic neuropathy (AAN) and ganglionic acetylcholine receptor (AChR) autoantibodies. Mean age was 61.4 years (standard deviation, 12.0 years). Ten patients had subacute symptom onset, six with an antecedent event. Eight patients had chronic AAN, characterized by insidious symptom onset, without antecedent event, and gradual progression. A majority of patients with high antibody values (>1.00 nmol/L) had a combination of sicca complex (marked dry eyes and dry mouth), abnormal pupillary light response, upper gastrointestinal symptoms, and neurogenic bladder. Chronic AAN segregated into two subgroups. One subgroup (N = 4) had low antibody titer (0.09 +/- 0.01 nmol/L) and a paucity of cholinergic symptoms. It was indistinguishable from pure autonomic failure. The other subgroup (N = 4) had high antibody titer (11.6 +/- 2.08 nmol/L), sicca complex, abnormal pupils, and neurogenic bladder; three had severe upper gastrointestinal dysfunction. Higher antibody titers correlated with greater autonomic dysfunction and more frequent cholinergic dysautonomia. These observations expand the clinical spectrum of AAN to include chronic cases, some being indistinguishable from pure autonomic failure, and support the concept that ganglionic AChR antibodies are important diagnostically and pathophysiologically in acquired dysautonomia.

- Abstract
Objective: To develop and establish the psychometric properties of a pain treatment willingness scale and identify factors associated with willingness to try specific pain treatments for spinal cord injury (SCI)-related pain., Design: As part of a larger study, a questionnaire was designed to assess willingness to use various pain medications and other types of pain treatments. This questionnaire, which included measures of pain severity, pain interference, mood, hope, and current use of pain treatments, was completed by persons with SCI recruited through the mail or in person., Subjects: One hundred fifteen persons completed the questionnaire (35% response rate). Seventy-two percent of the participants were men, mean age was 49.1 years, and average time elapsed since injury was 8 years., Results: Factor analysis indicated two factors-willingness to use opioids and willingness to use nonpharmacological treatment (i.e., physical therapy, relaxation methods and stress management, and alternative medicine). Internal consistency and convergent and divergent validity were established. Persons experiencing SCI-related pain were more willing to use pain treatments than those without current pain, and those who were currently using opioids reported greater willingness to use that treatment. Persons who reported SCI-related pain were more willing to use nonpharmacological treatments than opioid medications. Finally, participants demonstrated different degrees of willingness to use an opioid medication based on its name (i.e., "narcotic," "codeine," "morphine," "methadone")., Conclusions: Willingness to use a specific pain treatment may be a key factor mediating the behavior of using that specific treatment. Assessment of patient attitudes toward various treatments options, particularly regarding opioid medications, is warranted to optimize treatment adherence. Once the factors that determine these attitudes are identified, interventions to increase willingness to use nonpharmacological or opioid treatments can be designed and evaluated.

- Abstract
Studies on the psychological assessment and treatment of neuropathic pain conditions, including postherpetic neuralgia (PHN), diabetic neuropathy, complex regional pain syndrome, post spinal cord injury, post amputation, and AIDS-related neuropathy, are reviewed. Although limited information is currently available, the findings are consistent with the larger literature on chronic pain and indicate that the assessment of neuropathic pain needs to include measurement of multiple dimensions of quality of life. Mood, physical and social functioning, and pain-coping strategies such as catastrophizing and social support are all important domains. Clinical trials of psychological interventions have not been reported in the scientific literature. Case series of successful treatment of neuropathic pain are reported, primarily in the area of biofeedback. As with other chronically painful conditions, it is likely that cognitive-behavioral interventions will improve the quality of life in neuropathic pain conditions.

- Abstract
Studies on the psychosocial impact of neuropathic pain conditions, including postherpetic neuralgia, diabetic neuropathy, complex regional pain syndrome, post spinal cord injury, postamputation, and AIDS-related neuropathy, are reviewed. Although limited, data are consistent with the larger literature on chronic pain and indicate that neuropathic pain reduces quality of life, including mood and physical and social functioning. Depression and pain coping strategies such as catastrophizing and social support predict pain severity, and a single diary study demonstrates a prospective relation between depressed mood and increased pain. Clinical trials of psychological interventions have not been reported, although some case series of successful treatment of neuropathic pain are reported, primarily in the area of biofeedback. Given the evidence indicating the broad impact of neuropathic pain on many areas of function, it is surprising that so few studies have investigated the impact of psychological interventions in these populations.
