[A case of anti-NMDA-receptor encephalitis]. / Anti-NMDA-éntsefalit - klinicheskii sluchai

A clinical case of encephalitis caused by antibodies to NMDA-receptors is presented. This rare pathology is characterized by severe cognitive impairment and needs careful differential diagnosis.

Cognitive dysfunction during anti-NMDA-receptor encephalitis is present in early phase of the disease.

Anti-NMDA-receptor encephalitis is an autoimmune disorder with a well-defined set of clinical features including psychiatric changes (anxiety, agitation, bizarre behaviour, delusional or paranoid thoughts), epileptic seizures and cognitive disturbance followed by movement disorders including orofacial dyskinesias, alterations in the level of consciousness and dysautonomia. Although the cognitive changes are not always very clear at presentation, they can persist after recovery from the acute and often prolonged illness. However, there are few studies describing neuropsychiatric changes in depth, both in the early course of the disease and in long-term follow-up.

Health-related quality of life in patients with hereditary spastic paraplegia in Estonia.

STUDY DESIGN: Observational population-based cohort study. OBJECTIVES: The main aim of this study was to examine the relative effect of hereditary spastic paraplegia (HSP) on the health-related quality of life (HRQoL). METHODS: HRQoL was evaluated using a RAND 36-Item Health Survey 1.0 questionnaire. Fifty-eight patients received a questionnaire through mail and signed an informed consent. The results for the control group were obtained from the RAND-36 data collected in 2004 in the European Social Survey. R2.9.0 and Statistica 6.1 were used to analyze the RAND-36 data. SETTING: The study was performed in Estonia, a country with a population of 1.3 million. RESULTS: Completed questionnaires were received from 49 participants (response rate was 84.5%). The control group consisted of 549 individuals from the Estonian population. Patients with HSP had lower mean scores in all categories as compared with the control group. Six of the eight categories showed significant differences, with P<0.0001. For the vitality category, the P-value ranged from 0.000006 from 0.002, and the P-value for the mental health category ranged from 0.001 to 0.055. CONCLUSIONS: The HRQoL in patients with HSP was found to be significantly worse than that for the general population. The level of education might affect the HRQoL experienced by HSP patients.

The prevalence of depression in hereditary spastic paraplegia.

OBJECTIVE: To evaluate the prevalence of depression and sensitivity and specificity of the single-item interview 'Are you depressed?' for people with hereditary spastic paraplegia in Estonia. DESIGN: Single-item interview 'Are you depressed?' was used as a screening question for depression; all participants then completed the Beck Depression Inventory. SETTING: People with hereditary spastic paraplegia identified from the epidemiological database who agreed to participate in the study. MAIN MEASURES: Beck Depression Inventory, clinical interview. RESULTS: The epidemiological database consisted of 59 patients with clinically confirmed diagnosis of hereditary spastic paraplegia. Forty-eight of these consented to participate in the study. The Beck Depression Inventory score was higher than cut-off point in 58% (28/48) and lower in 42% (20/48). Of the study group, 44% (21/48) had mild, 13% (6/48) moderate and one person revealed severe depression. There was a statistically significant correlation between Beck Depression Inventory score and level of mobility; no other significant correlations with other measures were detected. Of the participants, 54% (26/48) had subjective complaints about depression and answered 'Yes' to the single-item interview 'Are you depressed?'. The sensitivity of the one-item interview in the hereditary spastic paraplegia group was 75% and specificity 75%. CONCLUSIONS: Our results show that mild depression is prevalent among people with hereditary spastic paraplegia. Although the single question may be helpful, it cannot be relied upon entirely when assessing a person for depression.

Clean intermittent self-catheterization in persons with multiple sclerosis: the influence of cognitive dysfunction.

BACKGROUND: Bladder problems are very common in persons with multiple sclerosis (PwMS). OBJECTIVE: The aim of this study was to investigate the ability of PwMS to learn clean intermittent self-catheterization (CISC). METHODS: The physical disability of 23 PwMS was evaluated with the Expanded Disability Status Scale (EDSS), and cognitive status was evaluated with the Brief Repeatable Battery of Neuropsychological Tests (BRB-N). CISC was taught by the same continence advisor who was blinded to the cognitive test results. The ability to learn CISC was evaluated immediately after sessions and 3 months later. Twenty-three consecutive PwMS participated in the study. RESULTS: In all, 87% (20/23) of the PwMS successfully finished CISC training. The number of lessons needed to acquire CISC skills differed significantly depending on the EDSS (Spearman r=0.682, P=0.0003), but the total cognitive decline subscore did not influence the ability to learn CISC. Only 13% (3/23) of the PwMS failed to learn CISC. The ability to learn CISC depended on the number of lessons needed to acquire CISC (r=-0.499, P=0.0313) and the EDSS score (r=-0.433, P=0.0390) but not on the course of the disease (r=0.125, P=0.5696) or on cognitive decline (r=-0.311, P=0.1480). After 3 months of follow-up, 30% (6/20) of the PwMS had ceased performing CISC. A follow-up indicated no statistically significant correlations among any of the subscores of the cognitive test battery, the EDSS score, the course of the disease, and the time required to learn CISC and effective bladder management. CONCLUSIONS: Our study thus confirmed that most (87%) PwMS were able to learn CISC in spite of cognitive dysfunction and therefore to improve their quality of life.

One question as a screening instrument for depression in people with multiple sclerosis.

OBJECTIVE: To evaluate how effectively one question 'Are you depressed?' works as a screening tool for depression in people with multiple sclerosis. DESIGN: The results from a single question were compared with formal clinical diagnosis and the classification from a standard questionnaire. SETTING: Estonian Multiple Sclerosis Centre, from October 2001 to April 2002. SUBJECTS: One hundred and thirty-four consecutive inpatients with multiple sclerosis. INTERVENTION: During two weeks of inpatient stay the mood disorder was analysed. On the basis of clinical interview and Beck Depression Inventory the diagnosis of depression was confirmed. MAIN MEASURES: Beck Depression Inventory and structured clinical interview. RESULTS: Fifty-seven per cent (77/134) of people with multiple sclerosis answered 'Yes' to the question 'Are you depressed?'. The diagnosis of depression was confirmed in 94% (72/77) of people with multiple sclerosis and not confirmed in 6% (5/77). Hence, the screening test sensitivity was 91%. Forty-three per cent (57/134) answered 'No'; 70% (40/57) did not have depression. In this case the sensitivity was 54%. In this group 30% (17/57) were actually depressed according to tests and clinical impression. The age, sex, duration of disease, cognitive abilities and physical disability did not influence consistency of the answers with test results and clinical opinion. CONCLUSIONS: One-question interview is a useful tool for screening for depression in people with multiple sclerosis as it confirms existing depression (sensitivity 91%), but the results should be treated with caution if the person denies mood problems.

Conservative bladder management in advanced multiple sclerosis.

Anticholinergics and intermittent catheterization are the cornerstones of bladder management in early multiple sclerosis (MS). In advanced MS however, bladder management is based more on tradition than on evidence. Nurses seem to deal with catheter problems and chronic incontinence. Despite the abundant use of indwelling catheters, there is a lack for guidelines on catheter-induced problems. The psychosexual and social impact of bladder problems in advanced MS is often neglected. The international multidisciplinary special interest group on sexual, urological and bowel dysfunction in MS (SUBDIMS) as a special interest group of the Rehabilitation in Multiple Sclerosis (RIMS) was confronted with a high variability in practice and a lack of guidelines. A literature review was prepared during three multidisciplinary expert meetings. This review will be the basis of further initiatives to improve the urological treatment of patients with advanced MS.

A questionnaire assessment of unmet needs for rehabilitation services and resources for people with multiple sclerosis: results of a pilot survey in five European countries. Needs Task group of MARCH (Multiple Sclerosis and Rehabilitation, Care and Health Services Research in Europe).

OBJECTIVE: To develop an international services and needs assessment instrument (SUN) for people with multiple sclerosis and their carers and to pilot this in different countries of the European Community. DESIGN: Interview study of people with multiple sclerosis, their carers and nominated key professionals examining the unmet needs of patients and carers. SETTING: Belgium, Estonia, Greece, Italy and the United Kingdom. MAIN OUTCOME MEASURES: Needs assessment questionnaire. RESULTS: The study comprised 137 people with multiple sclerosis, 125 carers and 111 professionals. Patients reported on average 2.9 unmet needs for themselves; their carers and professionals reported on average 2.4. Needs were categorized into seven broad categories. Due to difficulties experienced by the local researchers in distinguishing between needs and objectives a large proportion of needs had to be assigned to the 'other' category. CONCLUSIONS: The SUN is a valuable and practicable tool for the identification of unmet needs for people with multiple sclerosis and their carers. Formal validation and reliability testing of the different language versions is recommended.

Personality as a predictor of coping efforts in patients with multiple sclerosis.

The aim of the study was to explore personality traits as predictors of coping with disease-related distress in patients with multiple sclerosis (MS). All patients with clinically definite MS in a city with a population of approximately 100000 were asked to complete the NEO Personality Inventory and a multidimensional coping inventory (COPE). There was an 83% response rate yielding 49 patients for the study population and 49 controls, matched for age, gender and educational level to the MS-patients, were used as comparison. Only Neuroticism correlated significantly with emotion-focused coping in both groups. Extraversion and Openness to Experience were linked to task-oriented coping strategies in normal controls but not in the MS-group. Agreeableness was associated with avoidance-oriented coping strategies only in the MS-group. Thus, the relation of certain personality characteristics to the choice of strategies for coping with the disease-related distress appear to differ from coping with stressful problems in everyday life. As dispositional characteristics may interfere with adaptive coping responses, analysis of personality traits and coping strategies could contribute while attempting to relieve the consequences of chronic disease on everyday life.

The risk of motor neurone disease and multiple sclerosis is different in Estonians and Russians. Data from South Estonia.

Epidemiological studies were performed in South Estonia to establish the prevalence rate of multiple sclerosis (MS) and motor neurone disease (MND). The case finding method included information from the hospital records of the central hospital in the region-the University Hospital (for MS from 1942 to 1989), from all neurologists in the region, from the Estonian MS Society and Association of Muscular Disorders, and from nursing homes in the region. The prevalence day was 31 December 1989. MND incidence was established for the period of 1986-1995. The results demonstrated high prevalence rates of MS among native Estonians (55.3 per 100 000), somewhat lower prevalence among native-born representatives of other nationalities (43.6 per 100 000) and the lowest prevalence rate of MS among non-Estonian immigrants (26.6 per 100 000). The differences were not statistically significant. The results for MND demonstrated the opposite pattern. The mean annual incidence rate of MND for 10 years was statistically significantly higher among people of other nationalities (2.5 per 100 000) and Russians (2.6 per 100 000), and lower in native-born Estonians (1.1 per 100 000). No differences in health care or clinical picture were established. The reasons for the demonstrated differences in MND incidence remain unclear.

Motor neurone disease in South Estonia. Diagnosis and incidence rate.

The current study evaluated the diagnostic standards of MND and epidemiological markers of MND in Estonia. A total of 108 patients were referred to the University Hospital from 1986 to 1995 with the first suggested diagnosis or final diagnosis of amyotrophic syndrome, amyotrophic lateral sclerosis (ALS), progressive bulbar paralysis (PBP) or progressive muscular atrophy (PMA). In addition neurologists of the region and the National Society of Neuromuscular disorders were contacted. Some 94 patients satisfied the diagnostic criteria. The annual incidence rate in South Estonia and in the city of Tartu ranged from 0.5 to 2.8 per 100,000. The mean annual incidence rate in Tartu is 1.98 and in South Estonia in general 1.3. The highest incidence rate was 8.3 for men in the age group 60 to 64 years and 7.49 in the age group 70-74; among female patients the highest incidence rate -4.6 was in the age group from 65 to 69.
