Recommendations for terminology and the identification of neuropathic pain in people with spine-related leg pain. Outcomes from the NeuPSIG working group. Pain 2023; 164:1693-1704. [PMID: 37235637 PMCID: PMC10348639 DOI: 10.1097/j.pain.0000000000002919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 02/16/2023] [Accepted: 02/24/2023] [Indexed: 05/28/2023]
Abstract
ABSTRACT Pain radiating from the spine into the leg is commonly referred to as "sciatica," "Sciatica" may include various conditions such as radicular pain or painful radiculopathy. It may be associated with significant consequences for the person living with the condition, imposing a reduced quality of life and substantial direct and indirect costs. The main challenges associated with a diagnosis of "sciatica" include those related to the inconsistent use of terminology for the diagnostic labels and the identification of neuropathic pain. These challenges hinder collective clinical and scientific understanding regarding these conditions. In this position paper, we describe the outcome of a working group commissioned by the Neuropathic Pain Special Interest Group (NeuPSIG) of the International Association for the Study of Pain (IASP) which was tasked with the following objectives: (1) to revise the use of terminology for classifying spine-related leg pain and (2) to propose a way forward on the identification of neuropathic pain in the context of spine-related leg pain. The panel recommended discouraging the term "sciatica" for use in clinical practice and research without further specification of what it entails. The term "spine-related leg pain" is proposed as an umbrella term to include the case definitions of somatic referred pain and radicular pain with and without radiculopathy. The panel proposed an adaptation of the neuropathic pain grading system in the context of spine-related leg pain to facilitate the identification of neuropathic pain and initiation of specific management in this patient population.

SEZ6L2 Antibody-Associated Cerebellar Ataxia Responsive to Sequential Immunotherapy. NEUROLOGY(R) NEUROIMMUNOLOGY & NEUROINFLAMMATION 2022; 9:9/2/e1131. [PMID: 35031588 PMCID: PMC8759717 DOI: 10.1212/nxi.0000000000001131] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Accepted: 11/24/2021] [Indexed: 11/17/2022]
Abstract
Objectives Seizure-related 6 homolog like 2 (SEZ6L2) antibody–associated ataxia is an extremely rare disease. Six patients have been reported and none of them improved significantly with immunotherapy. Herein, we present the case of a patient with cerebellar ataxia and SEZ6L2 antibodies who benefited from immunotherapy, which dramatically altered the course of her disease. Methods We present a case report of a 73-year-old woman with progressive balance problems. Her condition had rapidly deteriorated in the 2 weeks before the admission to our hospital leading to repeated falls and eventually left her bed-ridden. Results She presented with severe trunk ataxia, bidirectional nystagmus, dysarthric speech, and persistent nausea. With the exception of cerebellar atrophy, extensive imaging studies revealed no pathology. SEZ6L2 antibodies were found in both CSF and serum. Over a period of 9 months, our patient received immunotherapy consisting of steroid pulse therapy, IV immunoglobulin infusions, rituximab, and cyclophosphamide. Consequently, her condition improved markedly, and she was discharged home from the neurologic rehabilitation unit. Discussion Our case report shows that intense sequential immunotherapy may considerably improve level of functioning in some patients with SEZ6L2 antibody–associated cerebellar ataxia. Classification of Evidence This provides Class IV evidence. It is a single observational study without controls.

Is the Preoperative Use of Antidepressants and Benzodiazepines Associated with Opioid and Other Analgesic Use After Hip and Knee Arthroplasty? Clin Orthop Relat Res 2021; 479:2268-2280. [PMID: 33982976 PMCID: PMC8445559 DOI: 10.1097/corr.0000000000001793] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Accepted: 04/05/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND Mental health disorders can occur in patients with pain conditions, and there have been reports of an increased risk of persistent pain after THA and TKA among patients who have psychological distress. Persistent pain may result in the prolonged consumption of opioids and other analgesics, which may expose patients to adverse drug events and narcotic habituation or addiction. However, the degree to which preoperative use of antidepressants or benzodiazepines is associated with prolonged analgesic use after surgery is not well quantified. QUESTION/PURPOSES (1) Is the preoperative use of antidepressants or benzodiazepine medications associated with a greater postoperative use of opioids, NSAIDs, or acetaminophen? (2) Is the proportion of patients still using opioid analgesics 1 year after arthroplasty higher among patients who were taking antidepressants or benzodiazepine medications before surgery, after controlling for relevant confounding variables? (3) Does analgesic drug use decrease after surgery in patients with a history of antidepressant or benzodiazepine use? (4) Does the proportion of patients using antidepressants or benzodiazepines change after joint arthroplasty compared with before? METHODS Of the 10,138 patients who underwent hip arthroplasty and the 9930 patients who underwent knee arthroplasty at Coxa Hospital for Joint Replacement, Tampere, Finland, between 2002 and 2013, those who had primary joint arthroplasty for primary osteoarthritis (64% [6502 of 10,138] of patients with hip surgery and 82% [8099 of 9930] who had knee surgery) were considered potentially eligible. After exclusion of another 8% (845 of 10,138) and 13% (1308 of 9930) of patients because they had revision or another joint arthroplasty within 2 years of the index surgery, 56% (5657 of 10,138) of patients with hip arthroplasty and 68% (6791 of 9930) of patients with knee arthroplasty were included in this retrospective registry study. Patients who filled prescriptions for antidepressants or benzodiazepines were identified from a nationwide drug prescription register, and information on the filled prescriptions for opioids (mild and strong), NSAIDs, and acetaminophen were extracted from the same database. For the analyses, subgroups were created according to the status of benzodiazepine and antidepressant use during the 6 months before surgery. First, the proportions of patients who used opioids and any analgesics (that is, opioids, NSAIDs, or acetaminophen) were calculated. Then, multivariable logistic regression adjusted with age, gender, joint, Charlson Comorbidity Index, BMI, laterality (unilateral/same-day bilateral), and preoperative analgesic use was performed to calculate odds ratios for any analgesic use and opioid use 1 year postoperatively. Additionally, the proportion of patients who used antidepressants and benzodiazepines was calculated for 2 years before and 2 years after surgery. RESULTS At 1 year postoperatively, patients with a history of antidepressant or benzodiazepine use were more likely to fill prescriptions for any analgesics than were patients without a history of antidepressant or benzodiazepine use (adjusted odds ratios 1.9 [95% confidence interval 1.6 to 2.2]; p < 0.001 and 1.8 [95% CI 1.6 to 2.0]; p < 0.001, respectively). Similarly, patients with a history of antidepressant or benzodiazepine use were more likely to fill prescriptions for opioids than patients without a history of antidepressant or benzodiazepine use (adjusted ORs 2.1 [95% CI 1.7 to 2.7]; p < 0.001 and 2.0 [95% CI 1.6 to 2.4]; p < 0.001, respectively). Nevertheless, the proportion of patients who filled any analgesic prescription was smaller 1 year after surgery than preoperatively in patients with a history of antidepressant (42% [439 of 1038] versus 55% [568 of 1038]; p < 0.001) and/or benzodiazepine use (40% [801 of 2008] versus 55% [1098 of 2008]; p < 0.001). The proportion of patients who used antidepressants and/or benzodiazepines was essentially stable during the observation period. CONCLUSION Surgeons should be aware of the increased risk of prolonged opioid and other analgesic use after surgery among patients who were on preoperative antidepressant and/or benzodiazepine therapy, and they should have candid discussions with patients referred for elective joint arthroplasty about this possibility. Further studies are needed to identify the most effective methods to reduce prolonged postoperative opioid use among these patients. LEVEL OF EVIDENCE Level III, therapeutic study.

Predictors of the use of analgesic drugs 1 year after joint replacement: a single-center analysis of 13,000 hip and knee replacements. Arthritis Res Ther 2020; 22:89. [PMID: 32317021 PMCID: PMC7175525 DOI: 10.1186/s13075-020-02184-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Accepted: 04/07/2020] [Indexed: 12/27/2022] Open
Abstract
Background Pain persists in a moderate number of patients following hip or knee replacement surgery. Persistent pain may subsequently lead to the prolonged consumption of analgesics after surgery and expose patients to the adverse drug events of opioids and NSAIDs, especially in older patients and patients with comorbidities. This study aimed to identify risk factors for the increased use of opioids and other analgesics 1 year after surgery and focused on comorbidities and surgery-related factors. Methods All patients who underwent a primary hip or knee replacement for osteoarthritis from 2002 to 2013 were identified. Redeemed prescriptions for acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and opioids (mild and strong) were collected from a nationwide Drug Prescription Register. The user rates of analgesics and the adjusted risks ratios for analgesic use 1 year after joint replacement were calculated. Results Of the 6238 hip replacement and 7501 knee replacement recipients, 3591 (26.1%) were still using analgesics 1 year after surgery. Significant predictors of overall analgesic use (acetaminophen, NSAID, or opioid) were (risk ratio (95% CI)) age 65–74.9 years (reference < 65), 1.1 (1.03–1.2); age > 75 years, 1.2 (1.1–1.3); female gender, 1.2 (1.1–1.3); BMI 30–34.9 kg/m2 (reference < 25 kg/m2), 1.1 (1.04–1.2); BMI > 35 kg/m2, 1.4 (1.3–1.6); and a higher number of comorbidities (according to the modified Charlson Comorbidity Index score), 1.2 (1.1–1.4). Diabetes and other comorbidities were not significant independent predictors. Of the other clinical factors, the preoperative use of analgesics, 2.6 (2.5–2.8), and knee surgery, 1.2 (1.1–1.3), predicted the use of analgesics, whereas simultaneous bilateral knee replacement (compared to unilateral procedure) was a protective factor, 0.86 (0.77–0.96). Opioid use was associated with obesity, higher CCI score, epilepsy, knee vs hip surgery, unilateral vs bilateral knee operation, total vs unicompartmental knee replacement, and the preoperative use of analgesics/opioids. Conclusions Obesity (especially BMI > 35 kg/m2) and the preoperative use of analgesics were the strongest predictors of an increased postoperative use of analgesics. It is remarkable that also older age and higher number of comorbidities predicted analgesic use despite these patients being the most vulnerable to adverse drug events.

Abstract
BACKGROUND Analgesic drugs are recommended to treat pain caused by osteoarthritis, and joint replacement should decrease the need for them. We aimed to determine the user rates of analgesic drugs before and after joint replacement. METHODS All patients who underwent a primary hip or knee replacement for osteoarthritis from 2002 to 2013 in a region of 0.5 million people were identified. Patients with revision or other joint replacements during the study period (operation date +/- two years) were excluded, leaving 6238 hip replacements (5657 patients) and 7501 knee replacements (6791 patients) for analyses. Medication data were collected from a nationwide Drug Prescription Register and the prevalence (with its 95% confidence intervals) of acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), mild opioids, strong opioids, and medications used for neuropathic pain was calculated in three-month periods two years before and after surgery. RESULTS Between two years and three months preoperatively, the proportion of patients who redeemed at least one type of analgesic drug increased from 28% (95% CI, 27-30%) to 48% (47-50%) on hip replacement patients and from 33% (32-34%) to 41% (40-42%) on knee replacement patients. Postoperatively, the proportions decreased to 23% (22-24%) on hip and to 30% (29-31%) on knee patients. Hip replacement patients used more NSAIDs (34% (32-35%) hip vs 26% (25-27%) knee, p < 0.001), acetaminophen (14% (13-15%) vs 12% (11-13%), p < 0.001), and mild opioids (14% (13-15%) vs 9% (8-9%), p < 0.001) than knee patients preoperatively, but postoperatively hip patients used less NSAIDs (12% (11-13%) vs 16% (15-16%), p < 0.001), acetaminophen (9% (8-10%) vs 11% (11-12%), p < 0.001), and mild opioids (5% (5-6%) vs 8% (7-8%), p < 0.001). CONCLUSION Use of analgesic drugs increases prior to joint replacement, and is reduced following surgery. However, a considerable proportion of patients continue to use analgesics in two-year follow-up.

Abstract
INTRODUCTION In this study we assessed the value of genetic screening for Fabry disease (FD) and hereditary ATTR amyloidosis in patients with idiopathic small-fiber neuropathy (SFN) or mixed neuropathy in a clinical setting. METHODS This was a Nordic multicenter study with 9 participating centers. Patients with idiopathic SFN or mixed neuropathy were included. Genetic sequencing of the TTR and GLA genes was performed. RESULTS There were 172 patients enrolled in the study. Genetic screening was performed in 155 patients. No pathogenic mutations in the TTR gene were found. A single patient had a possible pathogenic variant, R118C, in the GLA gene, but clinical investigation showed no firm signs of FD. DISCUSSION Screening for hereditary ATTR amyloidosis and FD in patients with idiopathic SFN or mixed neuropathy without any additional disease-specific symptoms or clinical characteristics in a Nordic population appears to be of little value in a clinical setting.

Clinical Management of Epilepsy With Glutamic Acid Decarboxylase Antibody Positivity: The Interplay Between Immunotherapy and Anti-epileptic Drugs. Front Neurol 2018; 9:579.

Abstract
Background: There is scanty guidance in the literature on the management of patients with glutamic acid decarboxylase (GAD65) antibody associated autoimmune epilepsy (GAD-epilepsy). GAD-epilepsy is a rare distinct neurological syndrome with a wide clinical spectrum. We describe six GAD-epilepsy patients with special emphasis on the treatment timing and the relationship between immunologic and anti-epileptic therapy. Methods: Six patients diagnosed with GAD-epilepsy in Tampere University Hospital who had received immunotherapy from 2013 to 2017 were retrospectively analyzed from patient records. Data about symptom onset, including antibody levels, magnetic resonance imaging (MRI), electroencephalograms, immunotherapy and anti-epileptic treatment timing and treatment responses were collected and analyzed. Kruskall-Wallis test was used in the statistical evaluation. Results: All patients were female aged 9–54 at symptom onset. Three had hypothyroidism, none had diabetes, two had migraine. Five patients had very high (>2,000 IU/ml) and one had high (52–251 IU/ml) GAD65 antibody titers. All patients presented with seizure disorders. Patients who received early initiation of immunotherapy (3–10 months) responded well to treatment; patients in whom the immunotherapy was started later (15–87 months) did not respond (p = 0.0495). The first patient was seizure-free after 1 year of regular intravenous immunoglobulin and one antiepileptic drug (AED). The second patient developed unilateral temporal lobe T2 signal changes in MRI; she responded well to immunotherapy, experiencing a significant reduction in seizure frequency and resolution of MRI abnormalities. However, seizures continued despite trials with several AEDs. The third patient responded well to immunoadsorption and rituximab with one AED, with lowering of GAD65 titers (from >2,000 to 300). There was a long delay in the diagnosis of GAD-epilepsy in the three patients who had developed refractory epilepsy, one with hippocampal sclerosis. They all received immunotherapy but none responded. However, AED modification or vagus nerve stimulation reduced the seizure frequency in two patients. Epilepsy surgery was ineffective. Conclusions: These results highlight the importance of early detection of GAD65 antibodies in refractory epilepsy as immunotherapy can be effective if administered in the early stages of the disease when it can prevent permanent brain tissue damage.

Abstract
INTRODUCTION The p.A1156T mutation alters the function of the voltage-gated sodium channel Nav1.4 on the muscle sarcolemma, causing a channelopathy without overt myotonia or periodic paralysis but with myalgic pain. METHODS A postal survey was conducted to assess the prevalence and characteristics of pain and related symptoms in individuals with the p.A1156T mutation. A specific questionnaire, intensity and interference subscales of the Brief Pain Inventory, pain drawing, Widespread Pain Index, quality of life (RAND-36), and the Beck Depression Inventory were completed. RESULTS Twenty of 24 patients replied. Current pain was reported by 16 respondents; the other 4 had experienced pain previously. Most commonly, pain was widespread and exercise-induced. The severity and the impact of pain on daily life were considerable, although varied. DISCUSSION This sodium channelopathy is another entity in the growing number of diseases causing widespread myalgic pain that resembles the pain seen in fibromyalgia syndrome.

Abstract
The use of high-dose polyclonal intravenous immunoglobulin (IVIG) in the treatment of autoimmune neurological diseases has expanded over the last decade. Based on controlled clinical trials IVIG can be considered currently as the first-line treatment in Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy and multifocal motor neuropathy, and it may be used as a rescue therapy in worsening myasthenia gravis. IVIG is a second-line therapy in dermatomyositis, stiff-person syndrome and pregnancy-associated or postpartum relapses of multiple sclerosis. Although the biological efficacy of IVIG is due to multiple effects on the immune system, many mechanisms are still unknown. The awareness of risks and complications of IVIG therapy has increased, but severe side effects are still considered rare. Due to increasing costs of this treatment, careful selection of patients who will benefit from IVIG is extremely important.

Abstract
OBJECTIVE To evaluate the volumetric brain magnetic resonance imaging (MRI) findings in a population-based sample of systemic lupus erythematosus (SLE) patients and to detect a possible relationship between cerebral MRI abnormalities and specific neuropsychiatric (NP) manifestations. METHODS The study population consisted of patients with SLE (n = 43) in Pirkanmaa Health Care District, Finland and of a sex- and age-stratified reference group from the general population (n = 43). In addition to a clinical neurological investigation, all subjects received a detailed neuropsychological assessment and an MRI study. Volumetric measures of cerebral atrophy as well as T1- and T2-weighted lesions were obtained. SLE activity was assessed by the European Consensus Lupus Activity Measure (ECLAM) index, and accumulated NP abnormalities were measured by the Systemic Lupus International Collaborating Clinics (SLICC) damage index. A cumulative lifetime dose of glucocorticoids was determined from the patientrecords. RESULTS Compared with controls, SLE patients had increased volumes of both T1- and T2-weighted lesions (p = 0.019 and p<0.0001, respectively) and increased cerebral atrophy (p<0.001). All the measured MRI parameters were statistically significantly higher in NPSLE than in non-NPSLE patients. In SLE patients, cerebral atrophy was associated with cognitive dysfunction, epileptic seizures, and cerebrovascular disease; T1-weighted lesions were associated with epileptic seizures and T2-weighted lesions with cognitive dysfunction. All MRI parameters correlated significantly with the SLICC index but not with the ECLAM index. A positive correlation was found between a cumulative dose of glucocorticoids and cerebral atrophy in SLE patients. CONCLUSION MRI abnormalities, including brain atrophy and T1- and T2-weighted lesions, are significantly more common in patients with SLE than in the general population and they are related to specific NP manifestations. Our findings also provide support for the organic aetiology of cognitive dysfunction in SLE.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to investigate the levels of three adipocytokines: leptin, adiponectin and adipsin, in serum and cerebrospinal fluid (CSF) of twins discordant for multiple sclerosis (MS). Adipose tissue is an important component connecting immune system and several tissues and organs including CNS. Fat cells produce adipocytokines, which seem to have a role in various autoimmune disorders including MS. METHODS Plasma samples were collected from twelve twins and CSF samples from four twins discordant for MS. The concentrations of interleukine (IL)-6, adiponectin, adipsin and leptin in plasma and CSF samples were determined by enzyme immuno assay. RESULTS A significant difference was seen in the adipocytokine levels in CSF samples. Twins with MS had higher concentrations of adiponectin (P = 0.039) and adipsin (P = 0.039), than their asymptomatic co-twins. CONCLUSION As adiponectin and adipsin levels in CSF did not correlate with their levels in plasma, it seems that there could be a secondary intrathecal synthesis of these adipocytokines in MS.

Abstract
Central nervous system vasculitides are rare and life-threatening diseases with challenging diagnostics. Their neurological symptom spectrum is multifaceted: the patient may have intense headache, confusion, decreased cognitive function, changes in consciousness, epileptic attacks and symptoms resembling multiple sclerosis. Angiographic investigations, magnetic resonance imaging of the brain and examination of cerebrospinal fluid will clarify the diagnosis, but brain biopsy may be required to confirm the diagnosis. In differential diagnostics, special attention should be paid to cerebrovascular vasoconstriction syndromes. Standard therapy of cerebral vasculitis includes corticosteroids often combined with immunosuppressants.

Abstract
BACKGROUND Chronic neuropathic pain in leprosy patients after completion of multi-drug therapy (MDT) is an under-researched problem. The reason why some leprosy patients develop it is unknown. In this study we evaluated the role of ongoing inflammation and small-fibre neuropathy as possible contributing factors for neuropathic pain. METHODS We assessed chronic neuropathic pain in 17 leprosy patients who had completed MDT and were attending a referral clinic in Hyderabad, India. All patients had a clinical assessment, intraepidermal nerve (IENF) assessment and quantitative sensory testing (QST), which included the testing of tactile and pinprick sensations using Semmes-Weinstein monofilaments and weighted needles method. Nine patients had a sural nerve biopsy (SNB). RESULTS Thirteen patients had a glove and stocking pattern of neuropathy. All nerve biopsies showed inflammation with intraneural inflammation and perineural thickening, and intraneural acid fast bacilli were observed in five biopsies. IENF analysis of the skin biopsy specimens in 16/17 patients showed a statistically significant reduction in IENF density (P < 0.001, Mann Whitney test) compared to control skin biopsies. Complete depletion of intraepidermal nerves was observed in six patients. QST also showed marked abnormalities. In 11 patients total sensory loss for all modalities was found, and in the other six patients the sensory function was seriously impaired. DISCUSSION There is evidence of ongoing intraneural inflammation in leprosy patients who have completed MDT. This may explain the occurrence of chronic neuropathic pain. Using IENF density measurement we have found significant small-fibre neuropathy in leprosy patients and the use of this tool could be expanded.

A quantitative method for the assessment of intraepidermal nerve fibers in small–fiber neuropathy. J Neurol 2005; 252:789-94. [PMID: 15789134 DOI: 10.1007/s00415-005-0743-x] [Citation(s) in RCA: 41] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2004] [Revised: 11/11/2004] [Accepted: 11/15/2004] [Indexed: 10/25/2022]
Abstract
OBJECTIVES The purpose of this paper is to present an easy-to-use and reproducible morphometrical method of determining the density of intraepidermal nerve fibers (IENF) per epidermal area with the corresponding reference range of the IENF-counts. METHODS Thirty patients and 22 controls were included in this study. The patients were divided into three groups: small-fiber (SFN), diabetic and demyelinating neuropathy. All subjects underwent punch skin biopsy. Specimens were fixed routinely in formalin and thereafter embedded in paraffin. Nerve fibers were revealed using immunoperoxidase staining with panaxonal antibody PGP 9.5. Using light microscopy, immunopositive nerves were counted morphometrically per epidermal area (NPEA) and, for comparison, per epidermal length (NPEL). RESULTS Both the NPEA and NPEL estimates of SFN and diabetic neuropathy group differed significantly from those of control specimen (p < 0.001 and p < 0.001, Mann-Whitney test). Our method of counting, NPEA, shows a good correlation to NPEL (r = 0.945). CONCLUSIONS IENF-counting by a new morphometric modification is reproducible and diagnostically sensitive and can easily be adopted in any laboratory familiar with the basic immunohistochemical methodology. The method is less dependent on costly technical support systems and seems to be less time consuming when compared with conventional methods for IENF-counting.

Abstract
OBJECTIVE To evaluate whether serum matrix metalloproteinase 9 (MMP-9) levels are associated with neuropsychiatric manifestations, particularly cognitive dysfunction, as evaluated by neuropsychological testing and brain magnetic resonance imaging (MRI) abnormalities in patients with systemic lupus erythematosus (SLE). METHODS MMP-9 determinations were made in 44 patients with SLE and 43 healthy controls who underwent a clinical neurologic and neuropsychological investigation in order to identify neuropsychiatric manifestations. Cerebral MRI scans with volumetric estimation of intracranial cerebrospinal fluid spaces, T1-weighted lesions, and T2-weighted lesions were performed for all subjects. SLE activity was assessed by the European Consensus Lupus Activity Measure (ECLAM) index, and accumulated neuropsychiatric abnormality was assessed by the Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology damage index. RESULTS No significant difference was found in serum MMP-9 levels between the overall group of SLE patients and controls. However, SLE patients who had at least 1 neuropsychiatric manifestation (NPSLE patients) had significantly higher serum MMP-9 concentrations than did SLE patients without neuropsychiatric syndromes (P = 0.009). Among patients with NPSLE, those with cognitive deficits had significantly higher concentrations of serum MMP-9 than did those with normal cognitive function (P = 0.027). Furthermore, serum MMP-9 levels had a significant positive correlation with the volumes of T1-weighted and T2-weighted lesions in the brain MRI (P = 0.031 and P = 0.015, respectively). The concentration of serum MMP-9 correlated significantly with the SLICC index but not with the ECLAM index. CONCLUSION Elevated levels of serum MMP-9 in patients with SLE may reflect neuropsychiatric involvement, particularly cognitive dysfunction. The serum MMP-9 concentration may be associated with small- vessel cerebral vasculopathy and increased risk of cerebral ischemic events in patients with SLE.

Abstract
Few data exist on the effects of specific Alzheimer's disease (AD)-related mutations on cognitive function. We present neuropsychological test results in eight members of a large kindred with variant Alzheimer's disease (VarAD) due to a deletion of the presenilin 1 (PS-1) gene, encompassing exon 9. The disease was neuropathologically characterized by the presence of large, unusual, "cotton wool" plaques (CWP). Four surviving patients were prospectively tested, and retrospective neuropsychological data were collected from additional four deceased patients. The neuropsychological evaluation was based on tests of verbal and visual memory, abstract thinking, and visuoconstructive and spatial functions. In addition, psychiatric symptoms were evaluated. In four patients, brain glucose metabolism was examined by positron emission tomography (PET). PET showed temporoparietal hypometabolism typical of AD. In addition, variable patterns of hypometabolism (hemispherical asymmetry and occipital accentuation) were related to individual deficits of cognitive performance. However, all these early-onset patients (age range 43-63 years) with a deletion mutation of PS-1 gene showed prominent memory impairment and deficits in visuoconstructive and intellectual functions.

Abstract
We present a cross-sectional, population-based neuropsychological study of systemic lupus erythematosus (SLE) patients identified within Tampere University Hospital district, Finland with 440,000 inhabitants. Patients with definite SLE in the age range of 16-65 years (n = 46) and matched controls (n = 46) underwent neurological examination and comprehensive neuropsychological testing. On the basis of medical examination, the SLE patients were divided into neuropsychiatric (NP+; n = 15) and nonneuropsychiatric (NP-; n = 31) cases. The neuropsychological test results revealed more prevalent cognitive impairment in the NP+ patients, indicating that this subgroup mostly accounts for neuropsychological changes in SLE. Most characteristic changes in NP+ were observed in domains of memory, psychomotor speed, and complex attention. This suggests nonspecific CNS involvement, which is in line with neurological manifestations of the disease.

Abstract
OBJECTIVE To assess the validity of the recently developed American College of Rheumatology (ACR) nomenclature for neuropsychiatric systemic lupus erythematosus (NPSLE). METHODS We conducted a cross-sectional, population-based study covering an area with 440,000 people. A total of 46 patients aged 16 to 65 years fulfilled the criteria for a definite diagnosis of SLE. One control for each patient matched by age, sex, education, and place of residence was randomly identified from the population register. All patients and controls underwent a clinical neurologic examination and neuropsychological testing. The data were analyzed using conditional logistic regression methods. RESULTS Forty-two patients (91%) and 25 controls (56%) fulfilled at least one of the ACR NPSLE criteria, which gave an odds ratio (OR) of 9.5 (95% confidence interval [CI] 2.2-40.8) but low specificity (0.46). Cognitive dysfunction was the most common syndrome detected in 37 patients (80%). A revised set of 16 criteria excluding the syndromes without evidence for neuronal damage resulted in improved specificity (OR 7.0, 95% CI 2.1-23.5, specificity 0.93). CONCLUSION The proposed 19 ACR criteria did not differentiate SLE patients from controls, nor NPSLE patients from other SLE patients. The revised NPSLE criteria proposed by us performed well in our population but should be evaluated in a larger patient population.

Abstract
OBJECTIVE To describe the prevalence of neuropsychiatric (NP) syndromes in a Finnish population of patients with systemic lupus erythematosus (SLE) and to classify them according to the recently developed American College of Rheumatology (ACR) nomenclature and case definitions for NPSLE. METHODS Cross-sectional, population-based study covering an area with 440,000 people. A total of 58 patients with a definite diagnosis of SLE and aged 16 to 65 years were found in the computerized database of the area hospitals. Of these, 46 (79%) agreed to participate. The diagnosis of various NP syndromes was based on clinical impression (H.A.) following history, examination, review of medical records, and neuropsychologic testing. RESULTS At least one NP syndrome was identified in 42 patients (91%). The most frequent manifestation was cognitive dysfunction (n = 37; 81%), followed by headache (n = 25; 54%) and mood disorder (n = 20; 43%). When mild NP syndromes (mild cognitive deficit, headache, mild depression, anxiety, electroneuromyography-negative polyneuropathy) were excluded, the prevalence of NPSLE dropped to 46%. CONCLUSIONS According to the ACR nomenclature, there is a high prevalence of NP manifestations in a population-based sample of patients with SLE. Most NP syndromes were classified as minor; if they were excluded, the 46% prevalence of NPSLE would be slightly less than estimated in previous studies.

Abstract
The occurrence of both multiple sclerosis (MS) and systemic lupus erythematosus (SLE) has previously been described in several members within the same family and in twins of successive generations, but the finding of both diseases in one patient is a great rarity. We here report on a rare coexistence of MS and SLE both in mother and daughter. Both patients fulfill the diagnostic criteria of primary-progressive subtype of MS as well as SLE. The finding constitutes supporting evidence of a common genetic background for these two autoimmune disorders.

She developed a reversible posterior leukoencephalopathy syndrome (RPLS) with typical MRI findings. Diffusion-weighted images during the first days after the onset of symptoms predicted a small irreversible lesion in the frontal lobe, verified on T2-weighted images 1 month later. The patient showed full recovery after high-dose steroid treatment.

Abstract
Paraneoplastic cerebellar degeneration (PCD) has been associated with a variety of neoplasms, most commonly with gynecologic tumors, breast cancer, small cell lung cancer, and Hodgkin's disease (HD). In some patients PCD is associated with circulating antineuronal antibodies like anti-Hu, anti-Yo or anti-Ri. Previously, only 5 patients with a new antineuronal antibody called anti-Tr, proposed to be specific for HD, have been reported. We describe 1 further patient with HD and reversible PCD with a decline in anti-Tr antibody titers in cerebrospinal fluid and serum corresponding to the improvement of clinical symptoms. At the present time the immunoreactive pattern observed in rat cerebellum is the only way to identify anti-Tr antibodies and differentiate them from other antibodies that immunoreact with the Purkinje cells.

Abstract
Thirty patients with systemic sclerosis (scleroderma) and 188 healthy controls were studied for class I and class II MHC antigens. All patients with scleroderma fulfilled the ARA preliminary criteria for systemic sclerosis. The frequencies of HLA antigens B8, DR3 and DR52 were higher in patients with scleroderma as compared with controls. Ten patients had anti-Scl-70 antibodies, and four of them (40%) had HLA-DR5 antigen compared to 19 of 188 controls (10%), P = 0.013. The relative risk for DR5 in anti-Scl-70-positive patients was 3.6 compared to 1.6 of DQ3 suggesting the primary significance of DR5 compared to DQ related factors. Patients with neurological manifestations had higher frequencies of B8 and DR3 than those with no neurological manifestations of scleroderma. Our results support the view that immunogenetic background is associated with different clinical subsets of systemic sclerosis.

Abstract
Thirty-one patients with SSc were studied. Eleven patients had anti-Scl-70-, six had anti-U1RNP-, three had anticentromere antibodies, and one both anti-Scl-70- and anticentromere antibodies. Eleven patients (35%) had neurological findings (trigeminal neuropathy, polyneuropathy, in some with myopathy). Eight of these patients (73%) had either anti-U1RNP- or anti-Scl-70-antibodies in their serum. These findings suggest that neurological manifestations are not as uncommon in SSc as previously reported. There are probably subgroups of patients who are more prone to neurological manifestations of scleroderma (mostly patients with anti-U1RNP and possibly those with anti-Scl-70 antibodies).

Abstract
Systemic sclerosis (scleroderma) is thought to be the least likely of the collagen vascular disorders to cause nervous system damage. We evaluated the peripheral neuromuscular manifestations in 32 patients with scleroderma. A clinically defined peripheral nervous system (PNS) lesion was manifest in 5 of 32 patients (16%), including 2 patients with trigeminal neuropathy and single cases of polyneuropathy, brachial plexopathy, and lumbosacral radiculopathy. Neurophysiological studies suggested subclinical PNS involvement in 6 additional patients (3 with distal axonal polyneuropathy, 1 with probable myopathy and superimposed polyneuropathy, 1 with trigeminal neuropathy, and 1 with focal ulnar neuropathy). Even though subjective muscular complaints were numerous (16 patients, 50%), a defined primary muscular disease could be demonstrated only in 5 patients (16%). Our results indicate that peripheral neuropathy in scleroderma is not as uncommon as previously estimated.

Abstract
INTRODUCTION The purpose of this study was to determine, whether there are any differences in the occurrence of nervous system involvement in different systemic rheumatic diseases. The further aim of the present study was to identify and distinguish primary involvement of the nervous system by these diseases and involvement that may be secondary to confounding factors. MATERIAL AND METHODS The patient population consisted of 122 patients with a connective tissue disease (42 with systemic lupus erythematosus (SLE), 48 with Sjögren's syndrome and 32 with scleroderma). The methods included neurological examination and standard electrophysiological tests. RESULTS At least one neurological defect was diagnosed in 69% of SLE patients, in 71% of Sjögren's syndrome patients and in 66% of scleroderma patients. Secondary factors might have contributed to the pathogenesis of neurological symptoms and signs in up to 25-34% of events. CONCLUSION No significant differences were noted in the occurrence of neurological events in patients with SLE, Sjögren's syndrome and scleroderma. The necessity to differentiate between neurological phenomena directly attributed to the systemic rheumatic disease and those which are totally unrelated or secondary events resulting indirectly from involvement of other organ systems is emphasized.

Abstract
We evaluated central nervous system and psychiatric involvement in a clinical sample of 32 patients with systemic sclerosis (SSc) (scleroderma). All patients underwent clinical neurological examination. Electroencephalography (EEG) and visual evoked potentials (VEPs) were also recorded. Prominent central nervous system (CNS) or psychiatric symptoms were present in 5 patients (16%), including encephalopathy, psychosis, anxiety disorder, grand mal seizures and transient ischemic attack. In addition, abnormal VEPs were recorded from 5/32 patients (16%), suggesting optic neuropathy. EEGs were mainly normal or showed only slight, nonspecific changes. Primary CNS involvement in scleroderma, however, could not be shown in any of the 5 cases with neuropsychiatric symptoms. Our results suggest that neuropsychiatric symptoms in SSc are, if not coincidental, indirectly caused by internal organ involvement of SSc or by possible overlapping connective tissue diseases. On the other hand, optic neuropathy might be a primary complication of SSc.
