Naming decline after left anterior temporal lobectomy correlates with pathological status of resected hippocampus.

PURPOSE: To evaluate the determinants of postoperative change in visual confrontation naming ability and the differential sensitivity of two common tests of confrontation naming. METHODS: In a group of 99 patients undergoing lobectomy of the left, language-dominant anterior temporal lobe, we examined naming ability using two measures: the 60 item Boston Naming Test (BNT), and the Visual Naming (VN) subtest of the Multilingual Aphasia Examination (MAE). ATL entailed resection of lateral temporal lobe followed by microsurgical complete removal of hippocampus. Language mapping was not performed. The status of the resected hippocampus was graded on a scale 0-4 of hippocampal sclerosis (HS). A dichotomous grouping HS- (grades 0 and 1, n = 34) and HS+ (grades 3 and 4, n = 61) was effected. Age at surgery, age of epilepsy onset, sex, extent of lateral temporal resection, Full-Scale IQ (FSIQ), and preoperative naming scores were also examined as potential predictors of pre- versus postoperative naming change. RESULTS: Preoperative BNT and VN scores were significantly worse for HS+ than for HS- (BNT, p < 0.05; VN, p = 0.001). Postoperatively, BNT and VN scores significantly declined for HS- as compared with HS+ patients (p < 0.001). For individual risk, the 90th centile of reliable change index (RCI) was used. By this criterion, of the total sample, 39% evidenced decline on the BNT and 17% evidenced decline on the VN. Logistic regression analysis with backward elimination showed HS to be the only predictor of decline in BNT and HS and sex to be the only predictors of VN decline. Males were more at risk than females. Age, age at onset, extent of lateral resection, preoperative scores, and FSIQ were not predictors. Using age at onset as a proxy for HS+/HS- we calculated probabilities for naming decline for given onset age. CONCLUSIONS: Both preoperative and postoperative change in naming ability are associated with the pathological status of the hippocampus. The potential interpretations and implications of these findings are discussed.

Variation between centers in technique and guidelines for liver biopsy.

Hospitals have few published guidelines to follow when performing a liver biopsy. In 1992, we began revising our protocol in an effort to institute new guidelines for our teaching hospitals. To assess the current practice of liver biopsy, we sent 500 multilingual questionnaires to international academic centers, and 85 U.S. centers were surveyed by telephone. The survey assessed: 1) patient preparation, 2) technical aspects of the biopsy, and 3) post-procedural care. One hundred and eighty international centers and 85 U.S. centers responded (total = 265). We found a wide variation in the practice of this surgical procedure at both national and international centers. Many Asian centers (73%) performed a bleeding time prior to liver biopsy. This practice was seen in only 36% of the U.S. centers. Most centers preferred platelet counts of 50,000/mm3 and above. The aspiration needle was more widely used in the U.S. (74%) and in many international centers, but Asian centers (61%) preferred a cutting needle. Thirty percent of Japanese centers performed more than 50% of their liver biopsies laparoscopically. Few laparoscopies were done at other centers. While about a quarter of the reported U.S., European, Asian, and South American centers observed patients for 4-6 hours after a biopsy, the majority of centers observed patients 10 hours or more. In addition to the wide variation seen, this survey provided us with an academic view of the contemporary practice of liver biopsy and an insight into how to redefine our present guidelines.

Renewal of the neurophysiology of language: functional neuroimaging.

Functional neuroimaging methods have reached maturity. It is now possible to start to build the foundations of a physiology of language. The remarkable number of neuroimaging studies performed so far illustrates the potential of this approach, which complements the classical knowledge accumulated on aphasia. Here we attempt to characterize the impact of the functional neuroimaging revolution on our understanding of language. Although today considered as neuroimaging techniques, we refer less to electroencephalography and magnetoencephalography studies than to positron emission tomography and functional magnetic resonance imaging studies, which deal more directly with the question of localization and functional neuroanatomy. This review is structured in three parts. 1) Because of their rapid evolution, we address technical and methodological issues to provide an overview of current procedures and sketch out future perspectives. 2) We review a set of significant results acquired in normal adults (the core of functional imaging studies) to provide an overview of language mechanisms in the "standard" brain. Single-word processing is considered in relation to input modalities (visual and auditory input), output modalities (speech and written output), and the involvement of "central" semantic processes before sentence processing and nonstandard language (illiteracy, multilingualism, and sensory deficits) are addressed. 3) We address the influence of plasticity on physiological functions in relation to its main contexts of appearance, i.e., development and brain lesions, to show how functional imaging can allow fine-grained approaches to adaptation, the fundamental property of the brain. In closing, we consider future developments for language research using functional imaging.

Emerging issues in Israel: commentaries in a global context.

Communication disorders in Israel is a well-established professional field, requiring academic training and dual certification in speech pathology and audiology. Entry level is a BA in communication disorders (comparable to a MA degree in the USA) and 1 year of work under supervision. It is possible to continue studies towards higher degrees (MA and PhD). We face the same problems as in the rest of the world with need for trained professionals in the social services and the need to deal with multilingual and multicultural issues.

International assessment of the internal consistency of respiratory symptoms. European Community Respiratory Health Study (ECRHS).

We aimed to assess cross-cultural validity of the reporting of respiratory symptoms in the European Community Respiratory Health Study (ECRHS). A random sample of subjects from the general population (aged 20-44 yr), from 35 centers in 15 countries, answered a questionnaire and underwent allergy tests and airway challenge with methacholine. The overall response rate to the questionnaire was 60% (n = 16,635). Exploratory factor analysis was used to identify how symptoms were grouped (i.e., to specify factor structure), using data from the United Kingdom. Subsequently, a confirmatory factor analysis of the prespecified structure for the United Kingdom was assessed for each country in consecutive nested models, increasing at each step the number of parameters forced to be equal to the United Kingdom, and assessing the goodness of fit. Variables were clustered in the same four groups (factors) in all countries. The four factors, mutually adjusted, were associated with either bronchial responsiveness, atopy, or smoking, which provides coherence for the separation of the four factors. In the confirmatory factor analysis, when the load of each of the symptoms in the corresponding factor was prespecified, all countries except Spain showed an adequate fit; in Spain there were differences in answers concerning asthma treatment. We conclude that the ECRHS multilingual translated respiratory symptoms questionnaire shows high internal consistency, suggesting that international comparisons are not affected by errors due to cross-cultural variations in the reporting of symptoms.

Impact of a media campaign for disaster mental health counseling in post-September 11 New York.

OBJECTIVE: After the September 11, 2001, terrorist attacks on the World Trade Center, the New York State Office of Mental Health (NYOMH) initiated a three-phase multifaceted, multilingual media campaign that advertised the availability of counseling services. This study evaluated the association between patterns of spending within this campaign and the volume of calls received and referred to a counseling program. METHODS: Spending on television, radio, print, and other advertising was examined, as was the corresponding volume of calls to the NetLife hotline seeking referrals to counseling services. RESULTS: From September 2001 to December 2002, $9.38 million was spent on Project Liberty media campaigns. Call volumes increased during months when total monthly expenditures peaked. Initially, flyers, billboards, and other material items accounted for most monthly expenses. Over time, spending for television and radio advertisements increased, whereas other advertising declined. Temporal patterns show that in periods after an increase in media spending, call volumes increased independently of other sentinel events such as the one-year anniversary of the attacks. CONCLUSIONS: Sustained advertising through multiple media outlets appeared to be effective in encouraging individuals to seek mental health services.

Enhancing research with migrant women through focus groups.

Recent systematic reviews of measurement strategies have identified a striking lack of data to support the validity of most questionnaires used with multiethnic, migrant populations. In the context of two ongoing research studies examining the reproductive health needs of migrant women in Canada, cultural validation was required for proposed study questionnaires and protocols in a total of 13 languages. Multilingual, multiethnic women with various migrant profiles were recruited from the community to review research materials in a series of focus groups. Recommendations by these women were made in relation to consent and interpretation procedures, development of trust in research, home visits after birth, approaches to sensitive topics, inclusion of discrimination as a research variable, and reimbursement of participants. Preliminary work applying focus-group methods to mixed ethno-cultural groups yielded valuable information on appropriateness of planned research.

Communicating health risks in the Pacific: scientific construct and cultural reality.

Health workers often communicate to people from a position of power rather than focusing on the needs of the receivers. This is usually clouded with jargon and the so-called principles of scientific accuracy. Often the use of science is to justify the health worker's position rather than to precipitate actions to promote health and achieve people's control over their lives. Communication involves a tripartite reciprocal interaction between the sender, receiver and the medium. This involves both science and art specific to the message, language, values and participants. If the ultimate purpose of communication is healthful action and community control, then scientificness of the explanations must be secondary. Therefore the art of getting the message across must be the priority rather than it being scientifically sound. This conflict is discussed in relation to experiences in the Pacific Islands. The communication of health risks in the Pacific involves the multi-tiered translation of scientific concepts and language into those of the target populations. The scientific concepts are usually occidental and need to be translated into vernacular worldviews and languages. Experiences in and examples from the Pacific have challenged the primacy of scientific explanations over the need to minimise health risks and increase of community control. For health promotion to succeed in multicultural and multilingual Pacific, New Zealand and Australia, the art and science of communicating health risks must be titrated against scientific explanations to appropriately and primarily promote health.

Improving accuracy of transcripts in qualitative research.

Everyone who has worked with qualitative interview data has run into problems with transcription error, even if they do the transcribing themselves. A thoughtful, accurate, reliable, multilingual transcriptionist with a quick turnaround time is worth her or his weight in gold. In this article, the authors examine some transcription circumstances that seem to bring about their own consistent set of problems. Based on their experiences, the authors examine the following issues: use of voice recognition systems; notation choices; processing and active listening versus touch typing; transcriptionist effect; emotionally loaded audiotaped material; class and/or cultural differences among interviewee, interviewer, and transcriptionist; and some errors that arise when working in a second language. The authors offer suggestions for working with transcriptionists as part of the qualitative research team.

DEC-net: the development of the European register of clinical trials on medicines for children.

BACKGROUND: The need to register a clinical trial in a public database has been widely discussed in the last few years. Several general clinical trial registers have been developed, but none are dedicated to children. A web-based register of trials on drug therapy in children was therefore developed. PURPOSE: The general objective of the project, called DEC-NET (European register of clinical trials on medicines for children - drug evaluation in children) and supported by the European Community, is to provide the scientific community with a flexible tool for promoting communication and collaboration among researchers, disseminating clinical trial results and facilitating patient access and recruitment to trials. METHODS: We identified a set of trial data to be collected, including general trial information, recruitment information, eligibility criteria, clinical trial characteristics, location and contact information, study drugs, study sponsor and results. The system was set up to allow authorized users (working in Italy, Spain, France and UK) to enter, handle and monitor the trial information. Medical data dictionaries (ie, ICD-9 and ATC) were used in order to make the data-entry and the search and data analysis procedures easier. A multilingual approach in data handling and presentation made accessing trial information in English and in the language of the country where the study is located feasible. Search and browsing tools were set up to allow investigators, researchers, and citizens to freely search and browse the entire register and access the details of trials meeting the search criteria. RESULTS: The DEC-net register (http://www.dec-net.org) was opened for trial notification and consultation. LIMITATIONS: DEC-net currently involves four European countries and is a pilot project. CONCLUSIONS: It is hoped that what has been achieved so far represents only the beginning of a long-term project, and the next step will be to extend the register's use to other European countries.

Development, feasibility and performance of a health risk appraisal questionnaire for older persons.

BACKGROUND: Health risk appraisal is a promising method for health promotion and prevention in older persons. The Health Risk Appraisal for the Elderly (HRA-E) developed in the U.S. has unique features but has not been tested outside the United States. METHODS: Based on the original HRA-E, we developed a scientifically updated and regionally adapted multilingual Health Risk Appraisal for Older Persons (HRA-O) instrument consisting of a self-administered questionnaire and software-generated feed-back reports. We evaluated the practicability and performance of the questionnaire in non-disabled community-dwelling older persons in London (U.K.) (N = 1090), Hamburg (Germany) (N = 804), and Solothurn (Switzerland) (N = 748) in a sub-sample of an international randomised controlled study. RESULTS: Over eighty percent of invited older persons returned the self-administered HRA-O questionnaire. Fair or poor self-perceived health status and older age were correlated with higher rates of non-return of the questionnaire. Older participants and those with lower educational levels reported more difficulty in completing the HRA-O questionnaire as compared to younger and higher educated persons. However, even among older participants and those with low educational level, more than 80% rated the questionnaire as easy to complete. Prevalence rates of risks for functional decline or problems were between 2% and 91% for the 19 HRA-O domains. Participants' intention to change health behaviour suggested that for some risk factors participants were in a pre-contemplation phase, having no short- or medium-term plans for change. Many participants perceived their health behaviour or preventative care uptake as optimal, despite indications of deficits according to the HRA-O based evaluation. CONCLUSION: The HRA-O questionnaire was highly accepted by a broad range of community-dwelling non-disabled persons. It identified a high number of risks and problems, and provided information on participants' intention to change health behaviour.

Verbal abilities in healthy elderly adults.

The Multilingual Aphasia Examination, a short battery of language measures, was administered to 61 healthy, community-dwelling adults (42 female, 19 male) 70 to 90 years old, and their performances were compared with the norms for younger participants. The intent was to investigate the decline of verbal abilities with advancing age and to consider the implications of such a decline for the interpretation of the performances of other elderly individuals. A significant age-related decline in performance was found on only one (Sentence Repetition) of the nine tests. Of note, Sentence Repetition is also the only test that makes specific demands on both short-term memory and serial auditory information processing. The relative stability of verbal performances from the early adult years to the ninth decade suggests that the occurrence of defective performances in older individuals is more likely to reflect the presence of "age-associated" disease rather than "normal" aging. Further, the findings suggest that normative standards derived from the performances of unselected, representative samples of elderly adults may not be adequate bases for clinical interpretation.

Variables predicting surgical outcome in symptomatic hydrocephalus in the elderly.

We prospectively studied 30 older patients who had shunt surgery for symptomatic hydrocephalus and measured outcome using serial videotaping of gait, neuropsychological testing, and the Katz index of activities of daily living. Twenty-three patients improved and 7 did not. Using univariate analysis and the Fisher exact test, we found that the following variables were significantly related to outcome: (1) time B-waves present on 24-hour CSF pressure record; (2) anterior/posterior ratio on slice 4 of regional cerebral blood flow study; (3) duration of dementia prior to surgery; and (4) gait abnormality preceding dementia. The following variables showed a trend towards significance: (1) time CSF pressure greater than 15 mm Hg; and (2) scoring either pass or fail on the Multilingual Visual Naming Test. We conclude that several variables are significantly associated with surgical outcome in symptomatic hydrocephalus in the elderly and can be used in deciding whether to recommend surgery.

Two years' experience with Web-based teleconsulting in dermatology.

A non-commercial teledermatology network based on store-and-forward operation was established in April 2002. The aim was to create an easy-to-use platform for teleconsultation services, where physicians could seek diagnostic advice in dermatology from a pool of expert consultants and where they could present and discuss challenging dermatology cases with special emphasis on diagnosis and therapy. An online moderated discussion forum was added in October 2003. During the first two years, 348 health-care professionals from 45 countries registered to use the Website. A total of 783 requests for consultations were answered; 285 requests concerned pigmented skin lesions, 440 requests were from the whole range of clinical dermatology and 58 requests were about non-melanoma skin cancer. Of a total of 133 requests analysed, 80 (60%) were answered within one day, 47 (35%) within one week, five (4%) within two weeks and one (1%) consultation was answered in more than two weeks. Our experience with a discretionary, non-commercial, multilingual Website for open-access teleconsulting in dermatology appears to be successful. The Website represents an example of user-generated content, together with active interaction between users, who can present and discuss cases with remote colleagues.

Cross-cultural validation of the Japanese Functional Assessment of Cancer Therapy-Anemia (FACT-An).

BACKGROUND: The Functional Assessment of Cancer Therapy-Anemia (FACT-An) questionnaire, which consists of a core questionnaire named the General Measure of the Functional Assessment of Cancer Therapy (FACT-G) and the Anemia additional concerns subscale, was developed in an English-speaking culture. The validation of the Japanese FACT-G was reported previously (Fumimoto et al., 2001), and, in this report, a cross-cultural validation for the subscale was performed. METHODS: The Japanese version was developed through an iterative forward-backward translation sequence used throughout the Functional Assessment of Chronic Illness Therapy (FACIT) Multilingual Translation Project. In evaluating psychometric performance, its construct validity was investigated by exploratory factor-analyses, and confirmed by Cronbach's alpha coefficient. RESULTS: The FACT-An was given to 180 patients with lung cancer. Using the 20 items of the Anemia subscale, a factor analysis extracted four factors of fatigue, chest condition, activities and headache. When analyzed as two extracted factors, fatigue, chest condition and headache were combined to be a major factor, although the minor factor of activities still remained. Thirteen of the 20 items construct the Fatigue additional concerns subscale. Cronbach's alpha coefficients for the Fatigue subscale (0.93) and the Anemia subscale (0.88) confirmed that, although these subscales had items that focus on different aspects of anemia or fatigue, each subscale was unidimensional. Clinical validity was indicated by moderate values of Spearman's correlation coefficients between Eastern Cooperative Oncology Group performance status rating (ECOG PSR) and the Anemia subscale (-0.50) or the Fatigue subscale (-0.48). CONCLUSION: Both the Fatigue subscale and the Anemia subscale are valid in Japan, indicating that FACT-An is an instrument that is applicable across cultures and particularly with a Japanese cancer population.

An evaluation of the quality and contents of asthma education on the World Wide Web.

STUDY OBJECTIVES: To measure the accessibility and quality of currently available asthma education World Wide Web sites using the following criteria: accessibility by readability, language, and download time; information quality based on inclusion of core educational concepts and compliance with Health On the Net (HON) principles; and utilization of innovative technology. DESIGN: Objective evaluation of 145 Web sites. MEASUREMENTS AND RESULTS: Four search engines or directories (Yahoo, HON, Alta Vista, and Healthfinder) were searched for "asthma, patient information." A maximum of 50 Web sites from each search engine or directory was evaluated. Only 90 of the 145 Web sites actually contained asthma educational material. The mean (+/- SD) time necessary to open each Web site on a 28.800-bits-per-second modem was 33.6 ( +/- 36.6) s. The mean number of graphics on the Web sites was 24.6 ( +/- 30.2) files per page. The educational material required a mean reading level beyond the 10th grade. Only nine Web sites contained multilingual asthma education material. The mean number of HON principles with which the Web sites conformed was 6.3 ( +/- 1.0) of 8 principles; 14 Web sites conformed to all the HON criteria. The average Web site contained 4.9 (+/- 2.5) of 8 core asthma educational concepts, and only 20 Web sites contained all 8 educational concepts. Very few Web sites utilized innovative educational technology. CONCLUSIONS: While patient asthma education Web sites are common, asthma educational material contains many accessibility barriers, is highly variable in quality and content, and takes little innovative use of technology. Patient educational material currently available on the World Wide Web fails to meet the information needs of patients.

European cerebrospinal fluid consensus group--a TeamRoom (Lotus Notes)-based communication network.

A group of clinical neurochemists from all over Europe used TeamRoom to share information and to trace their discussions in a computer network. TeamRoom is a Lotus Notes based groupware tool enabling collaboration amongst geographically dispersed teams. As a result of this work a picture is emerging in the virtual TeamRoom space that represents a new kind of consensus in the use of cerebrospinal fluid analysis for diagnosis of neurological diseases. This kind of consensus differs from the conventional written report in giving a more complex and potentially richer representation of the field, in which both common views and minority perspectives are revealed. If direct access to this work is made available to other clinical neurochemists for consultation via a website, they may see their own practice in a wider context. This approach to improving different evolving traditions is more suitable for a global multicultural environment than a singular view of best practice produced by a more traditional process of group discussion. We refer to the benefits of a mixture of face to face meetings, collaboration in TeamRoom and teleconferencing for work in a non-hierarchical, multicultural and multilingual group. We suggest that the TeamRoom concept is a valuable model for enhancing self-organized harmonization across the developing European Union.

Facilitating cleft palate team participation of culturally diverse families in South Africa.

OBJECTIVE: The Facial Cleft Deformities Clinic, University of Pretoria, Pretoria, South Africa, provides interdisciplinary team services to patients with cleft lip and palate and craniofacial anomalies. They represent the "rainbow nation" of South Africa and reflect the multicultural and multilingual nature of the population, which poses a challenge to effective and accountable service delivery. The aim of this study was to explore some cultural variations that exist in black families that influence their participation in the team approach and to describe the assets of families that may be used to empower them and to enhance service delivery. DESIGN: A descriptive survey research design. A questionnaire-by-interview procedure was utilized during routine visits of 35 black families to the Facial Cleft Deformities Clinic. RESULTS: The results are discussed from an ethnographic perspective of the family and describe the knowledge base of the participants, the diagnosis and treatment of the children's cleft lip and palate, family structure and support systems, family income and education, and the geographical distribution of the participants. Implications for building family partnerships and for improving professionals' cultural competence in order to improve the quality of service delivery are presented. CONCLUSIONS: By viewing cultural differences on a continuum, following the asset-based approach, applying knowledge based on contextually relevant research, and recognizing family uniqueness, families may be empowered to participate fully in the team approach to support their children with cleft lip and palate and craniofacial anomalies in attaining their full potential in the South African context.
