Effects of immigration on the prevalence of malaria in rural areas of the Amazon basin of Brazil

Epidemiological studies were conducted on malaria in three rural areas of the Amazon basin in the State of Rondônia: the town of Costa Marques, Forte Príncipe da Beira (Fort), and an immigrant settlement in the nearby forest. These studies were instituted to document the malaria problem and to describe the role of immigration on its distribution and prevalence. Hospital records in the town show that the number of malaria cases increased five fold from 1983 to 1987 and that the predominant malaria parasite changel from Plasmodium vivax to P. falciparum. Increased malaria followed increased immigration and colonization of the forest. A series of epidemiologic studies suggested the linkage between malaria and immigration as the prevalence of malaria was 1-2% at the Fort, a stable community, 8-9% at Costa Marques, a growing community, and 14-26% in the new settlements in the forest.

ADOS: an educational primary prevention programme for preventing excess body weight in adolescents.

OBJECTIVE: The prevalence of adolescent obesity has increased considerably over the past decade in Switzerland and has become a serious public health problem in Europe. Prevention of obesity using various comprehensive programmes appears to be very promising, although we must admit that several interventions had generally disappointing results compared with the objectives and target initially fixed. Holistic programmes including nutritional education combined with promotion of physical activity and behaviour modification constitute the key factors in the prevention of childhood and adolescent obesity. The purpose of this programme was to incorporate nutrition/physical education as well as psychological aspects in selected secondary schools (9th grade, 14-17 years). METHODS: The educational strategy was based on the development of a series of 13 practical workshops covering wide areas such as physical inactivity, body composition, sugar, energy density, invisible lipids, how to read food labels, is meal duration important? Do you eat with pleasure or not? Do you eat because you are hungry? Emotional eating. For teachers continuing education, a basic highly illustrated guide was developed as a companion booklet to the workshops. These materials were first validated by biology, physical education, dietician and psychologist teachers as well as school medical officers. RESULTS: Teachers considered the practical educational materials innovative and useful, motivational and easy to understand. Up to now (early 2008), the programme has been implemented in 50 classes or more from schools originating from three areas in the French part of Switzerland. Based on the 1-week pedometer value assessed before and after the 1 school-year programme, an initial evaluation indicated that overall physical placidity was significantly decreased as evidenced by a significant rise in the number of steps per day. CONCLUSION: Future evaluation will provide more information on the effectiveness of the ADOS programme.

A collaborative approach for incorporating forensic case data into crime investigation using criminal intelligence analysis and visualisation

There is an increasing awareness that the articulation of forensic science and criminal investigation is critical to the resolution of crimes. However, models and methods to support an effective collaboration between these partners are still poorly expressed or even lacking. Three propositions are borrowed from crime intelligence methods in order to bridge this gap: (a) the general intelligence process, (b) the analyses of investigative problems along principal perspectives: entities and their relationships, time and space, quantitative aspects and (c) visualisation methods as a mode of expression of a problem in these dimensions. Indeed, in a collaborative framework, different kinds of visualisations integrating forensic case data can play a central role for supporting decisions. Among them, link-charts are scrutinised for their abilities to structure and ease the analysis of a case by describing how relevant entities are connected. However, designing an informative chart that does not bias the reasoning process is not straightforward. Using visualisation as a catalyser for a collaborative approach integrating forensic data thus calls for better specifications.

Interoperability issues between learning object repositories and metadata harvesters

In this paper we describe an open learning object repository on Statistics based on DSpace which contains true learning objects, that is, exercises, equations, data sets, etc. This repository is part of a large project intended to promote the use of learning object repositories as part of the learning process in virtual learning environments. This involves the creation of a new user interface that provides users with additional services such as resource rating, commenting and so. Both aspects make traditional metadata schemes such as Dublin Core to be inadequate, as there are resources with no title or author, for instance, as those fields are not used by learners to browse and search for learning resources in the repository. Therefore, exporting OAI-PMH compliant records using OAI-DC is not possible, thus limiting the visibility of the learning objects in the repository outside the institution. We propose an architecture based on ontologies and the use of extended metadata records for both storing and refactoring such descriptions.

Genetic survey of "spinturnix sp" (Acari, Mesostigmata) and their bat hosts in Western Palearctic

SUMMARY : The coevolution between two intimately associated organisms, like host and parasite, is a widely investigated theme in evolutionary biology. Recently, the use of genetic data in the study of host-parasite systems evidences that the genetic information from some parasites can complement genetic data from their hosts and thus may help to better understand their host's evolutionary history. Phylogenetic and population genetic aspects of bat parasites have been poorly investigated. Spinturnicid mites are highly specialized ectoparasites, exclusively associated with bats and therefore represent an ideal model to extant our knowledge on bat and parasite biology and on their coevolutionary history. In this thesis, I developed several molecular markers (mitochondrial DNA) to compare the genetic patterns of Spinturnix mites with their bat hosts at different levels. The molecular co-phylogeny between Spinturnix sp. and their bat hosts suggests a partial cospeciation and the occurrence of failure to speciate events and multiple host switches. Thus, Spinturnix mites do not exactly mirror the phylogenetic pattern of their hosts, despite their intimate association. Similar roosting habits of the hosts seem to promote host switches between different species, as far as ecological conditions are favourable. The phylogeographic study of the Maghrebian bat M. punicus in the Mediterranean area confirms the presence of M. punicus in North Africa, Corsica and Sardinia and highlights that islands and mainland are genetically highly divergent. The comparison between the parasitic mite S. myoti and the Maghrebian bat suggests that the phylogeographic pattern of the mite is moulded by its host, with open water as main barrier for host and parasite dispersal. Moreover, the unique presence of a European S. myoti lineage on M. punicus from Corsica strongly suggests the former presence of mouse-eared bats (M. myotis and/or M. blythii) in Corsica. By highlighting the probable presence of a nowadays locally extinct host species, S. myoti may represent a good proxy for inferring complex evolutionary history of bat hosts. Finally, population genetic surveys of S. myoti and S. bechsteinii suggest that these mites benefit from close contacts between individuals during the mating season and/or hibernation to disperse among remote colonies. The contrasted genetic patterns of these two distinct bat-mite systems evidence that bat social structure is a determinant factor of the genetic structure of mite populations. Altogether, this PhD thesis demonstrates the usefulness of parasites to gather information about their bat hosts. In addition, my results illustrate how different ecological and biological characteristics of bat species allow the emergence of a surprising diversity in the genetic patterns of the parasites, which may contribute to the diversification and speciation of parasites. RESUME : La co-évolution entre deux organismes intimement liés, comme un parasite et son hôte, fait partie des questions largement étudiées en biologie évolutive. Récemment, l'utilisation de données génétique dans l'étude des interactions hôte-parasite a montré que l'information génétique de certains parasites peut compléter les données génétiques de l'hôte et ainsi peut éclairer l'histoire évolutive de leur hôte. Très peu études ont étudié les interactions entre les chauves-souris et leurs parasites d'un point de vue moléculaire. Les acariens du genre Spinturnix sont des ectoparasites très spécialisés exclusivement associés aux chauves-souris. Ils représentent donc un model idéal pour élargir nos connaissances tant sur l'écologie des parasites de chauves-souris que sur leur coévolution. Durant cette thèse, plusieurs marqueurs moléculaires (ADN mitochondrial) ont été développés pour ainsi comparer la distribution de la variation génétique des parasites du genre Spinturnix avec celle de leurs hôtes, et ceci à différents niveaux. Tout d'abord, la co-phylogénie moléculaire entre les espèces de Spinturnix et les leurs hôtes révèle une co-spéciation partielle ainsi que la présence d'événement de non spéciation et de transferts horizontaux. Ces parasites ne reflètent donc pas entièrement l'histoire évolutive de leurs hôtes, malgré leurs intimes associations. La cohabitation de plusieurs espèces de chauves-souris dans un même gîte permet aux parasites un transfert entre différentes espèces, atténuant ainsi leur degré de co-spéciation. Deuxièmement, l'étude phylogéographique du marin du Maghreb dans le bassin Méditerranéen confirme sa présence en Afrique du Nord, en Corse et en Sardaigne. La comparaison avec un de ses parasites S. myoti suggère que la répartition génétique de S. myoti est façonnée par celle de leurs hôtes, avec les étendues d'eau comme barrière principale tant à la dispersion de l'hôte que de son parasite. De plus, la présence unique d'une lignée européenne de ces parasites sur des marins du Maghreb de Corse suggère fortement la présence du grand ou petit marin en Corse dans le passé. En reflétant la présence potentielle à un endroit donné d'une espèce de chauve-souris actuellement disparue, S. myoti peut représenter une bonne alternative pour comprendre l'histoire évolutive complexe des chauves-souris. Finalement, l'étude des structures génétiques des populations des parasites S. myoti et S. bechsteinii suggère que les contacts corporels entre chauves-souris durant la saison de reproduction ou l'hibernation peuvent permettre la dispersion des parasites entre des colonies éloignées géographiquement. La différence de structure génétique entre ces deux associations particulières montre que la structure génétique des populations de parasites dépend fortement des traits d'histoire de vie de son hôte. Dans l'ensemble, cette thèse démontre l'importance des parasites pour amener des informations sur leurs hôtes, les chauves-souris. Elle illustre aussi comment les différences écologique et biologique des différentes espèces de chauves-souris peuvent amener une étonnante diversité de structure génétique au sein de populations de parasites, ce qui peut peut-être contribuer à la diversification et à la spéciation des parasites.

Major depressive disorders in the general hospital: how to implement guidelines.

OBJECTIVE: An implementation study that evaluated the impact of previously adopted guidelines on the clinical practice of medical residents was conducted to improve the recognition and treatment of major depressive disorders (MDDs) in hospitalized patients with somatic diseases. METHODS: Guidelines were implemented in two wards (ENT and oncology) using intranet diffusion, interactive sessions with medical residents, and support material. Discharge letters of 337 and 325 patients, before and after the intervention, respectively, were checked for statement of diagnosis or treatment of MDDs and, in a post hoc analysis, for any mention about psychiatric management. RESULTS: No difference was found in the number of diagnosed or treated MDDs before and after the intervention. However, significantly more statements about psychological status (29/309 vs. 13/327) and its management (36/309 vs. 19/327) were observed after the intervention (P<.01). CONCLUSION: The intervention was not successful in improving the management of MDDs. However, a possible effect on general psychological aspects of medical diseases was observed.

La metàfora com a procés cognitiu : el futbol és una guerra

Tradicionalment, la metàfora ha estat estudiada pels filòlegs com una figura retòrica utilitzada sobretot en la poesia. Recentment, però, la lingüística cognitiva s'ha interessat per la metàfora. Actualment, a partir dels estudis de Lakoff i Johnson, s'ha demostrat que aquesta figura retòrica no només és una figura estilística, sinó que, a més a més, és reflex d'un procés cognitiu que impregna tot el nostre llenguatge i pensament. Els humans en la nostra vida quotidiana, constantment, conceptualitzem àrees més abstractes de la nostra experiència mitjançant dominis més concrets.D'entrada, farem un breu recorregut sobre la història dels estudis que tracten la metàfora: partirem dels clàssics i arribarem al segle XX amb els estudis de Lakoff i Johnson. En segon lloc, explicarem la metàfora dins el marc teòric de la semàntica cognitiva. En tercer lloc, estudiarem el llenguatge bèl·lic utilitzat per parlar del futbol. Finalment, analitzarem els tres tipus de metàfores - estructurals, ontològiques i orientatives - que podem trobar en els diaris esportius, centrant-nos, però, en la metàfora estructural EL FUTBOL ÉS UNA GUERRA. L'objectiu del nostre estudi és analitzar metàfores que usem en la nostra vida quotidiana per parlar de l'esport, cenyint-nos en el futbol. Concretament, la nostra anàlisi se centrarà, dins de l'àmbit dels mitjans de comunicació, en els diaris esportius. Aquest treball no només hauria de servir per adonar-nos de les metàfores que impregnen el món dels esports, sinó que, a més a més, hauria de servir per adonar-nos dels motius pels quals fem servir aquestes metàfores i no unes altres, uns motius que, com ens mostren els estudiosos Lakoff i Johnson, estan relacionats amb la nostra cultura i la relació que mantenim amb el món que ens envolta.

Sociodemographic and occupational risk factors associated with the development of different burnout types: the cross-sectional University of Zaragoza study

BACKGROUND: Three different burnout types have been described: The "frenetic" type describes involved and ambitious subjects who sacrifice their health and personal lives for their jobs; the "underchallenged" type describes indifferent and bored workers who fail to find personal development in their jobs, and the "worn-out" in type describes neglectful subjects who feel they have little control over results and whose efforts go unacknowledged. The study aimed to describe the possible associations between burnout types and general sociodemographic and occupational characteristics. METHODS: A cross-sectional study was carried out on a multi-occupational sample of randomly selected university employees (n = 409). The presence of burnout types was assessed by means of the "Burnout Clinical Subtype Questionnaire (BCSQ-36)", and the degree of association between variables was assessed using an adjusted odds ratio (OR) obtained from multivariate logistic regression models. RESULTS: Individuals working more than 40 hours per week presented with the greatest risk for "frenetic" burnout compared to those working fewer than 35 hours (adjusted OR = 5.69; 95% CI = 2.52-12.82; p < 0.001). Administration and service personnel presented the greatest risk of "underchallenged" burnout compared to teaching and research staff (adjusted OR = 2.85; 95% CI = 1.16-7.01; p = 0.023). Employees with more than sixteen years of service in the organisation presented the greatest risk of "worn-out" burnout compared to those with less than four years of service (adjusted OR = 4.56; 95% CI = 1.47-14.16; p = 0.009). CONCLUSIONS: This study is the first to our knowledge that suggests the existence of associations between the different burnout subtypes (classified according to the degree of dedication to work) and the different sociodemographic and occupational characteristics that are congruent with the definition of each of the subtypes. These results are consistent with the clinical profile definitions of burnout syndrome. In addition, they assist the recognition of distinct profiles and reinforce the idea of differential characterisation of the syndrome for more effective treatment.

Cluster analysis of behavioural and event-related potentials during a contingent negative variation paradigm in remitting-relapsing and benign forms of multiple sclerosis

Background: Event-related potentials (ERPs) may be used as a highly sensitive way of detecting subtle degrees of cognitive dysfunction. On the other hand, impairment of cognitive skills is increasingly recognised as a hallmark of patients suffering from multiple sclerosis (MS). We sought to determine the psychophysiological pattern of information processing among MS patients with the relapsing-remitting form of the disease and low physical disability considered as two subtypes: 'typical relapsing-remitting' (RRMS) and 'benign MS' (BMS). Furthermore, we subjected our data to a cluster analysis to determine whether MS patients and healthy controls could be differentiated in terms of their psychophysiological profile.Methods: We investigated MS patients with RRMS and BMS subtypes using event-related potentials (ERPs) acquired in the context of a Posner visual-spatial cueing paradigm. Specifically, our study aimed to assess ERP brain activity in response preparation (contingent negative variation -CNV) and stimuli processing in MS patients. Latency and amplitude of different ERP components (P1, eN1, N1, P2, N2, P3 and late negativity -LN) as well as behavioural responses (reaction time -RT; correct responses -CRs; and number of errors) were analyzed and then subjected to cluster analysis. Results: Both MS groups showed delayed behavioural responses and enhanced latency for long-latency ERP components (P2, N2, P3) as well as relatively preserved ERP amplitude, but BMS patients obtained more important performance deficits (lower CRs and higher RTs) and abnormalities related to the latency (N1, P3) and amplitude of ERPs (eCNV, eN1, LN). However, RRMS patients also demonstrated abnormally high amplitudes related to the preparation performance period of CNV (cCNV) and post-processing phase (LN). Cluster analyses revealed that RRMS patients appear to make up a relatively homogeneous group with moderate deficits mainly related to ERP latencies, whereas BMS patients appear to make up a rather more heterogeneous group with more severe information processing and attentional deficits. Conclusions: Our findings are suggestive of a slowing of information processing for MS patients that may be a consequence of demyelination and axonal degeneration, which also seems to occur in MS patients that show little or no progression in the physical severity of the disease over time.

E-government and Public Services : a Case Study of the Inter-administrative Portal CAT365. Research report (sythesis document)

Aquest estudi analitza els usos de les TIC a l'administració autonòmica catalana. De forma més específica, l'estudi se centra en la interacció entre l'ús d'un vessant concret de les TIC, la xarxa Internet, per part de l'administració pública, i determinats aspectes centrals d'aquest tipus d'institucions: la seva organització i estructura internes, la provisió de serveis públics o la relació amb altres agents socials. Hem analitzat, doncs, el fenomen del govern electrònic en el marc particular de la Generalitat de Catalunya, estudiant-ne el grau de desenvolupament i penetració, les seves característiques més remarcables i els problemes més importants que s'hi plantegen. El projecte de recerca es concreta en un estudi de cas sobre un projecte d'innovació específic però de gran abast, que es trobava en el moment de realització de l'estudi en la seva primera fase d'implementació: el projecte Administració Oberta de Catalunya (AOC). Concretament ens hem centrat en el vessant d'aquesta iniciativa pública que es concretava en la creació d'un portal interadministratiu a Internet, el portal www.cat365.net, destinat a proveir electrònicament serveis públics de totes les administracions que operen a Catalunya. L'estudi analitza les transformacions internes de l'administració que s'hi poden trobar associades i els elements que les condicionen, tant positivament com negativa. Igualment, intentem analitzem el que aquestes transformacions poden suposar per a la relació entre els ciutadans i les institucions públiques.

Quantitative electroencephalography reveals different physiological profiles between benign and remitting-relapsing multiple sclerosis patients

BACKGROUND A possible method of finding physiological markers of multiple sclerosis (MS) is the application of EEG quantification (QEEG) of brain activity when the subject is stressed by the demands of a cognitive task. In particular, modulations of the spectral content that take place in the EEG of patients with multiple sclerosis remitting-relapsing (RRMS) and benign multiple sclerosis (BMS) during a visuo-spatial task need to be observed. METHODS The sample consisted of 19 patients with RRMS, 10 with BMS, and 21 control subjects. All patients were free of medication and had not relapsed within the last month. The power spectral density (PSD) of different EEG bands was calculated by Fast-Fourier-Transformation (FFT), those analysed being delta, theta, alpha, beta and gamma. Z-transformation was performed to observe individual profiles in each experimental group for spectral modulations. Lastly, correlation analyses was performed between QEEG values and other variables from participants in the study (age, EDSS, years of evolution and cognitive performance). RESULTS Nearly half (42%) the RRMS patients showed a statistically significant increase of two or more standard deviations (SD) compared to the control mean value for the beta-2 and gamma bands (F = 2.074, p = 0.004). These alterations were localized to the anterior regions of the right hemisphere, and bilaterally to the posterior areas of the scalp. None of the BMS patients or control subjects had values outside the range of +/- 2 SD. There were no significant correlations between these values and the other variables analysed (age, EDSS, years of evolution or behavioural performance). CONCLUSION During the attentional processing, changes in the high EEG spectrum (beta-2 and gamma) in MS patients exhibit physiological alterations that are not normally detected by spontaneous EEG analysis. The different spectral pattern between pathological and controls groups could represent specific changes for the RRMS patients, indicative of compensatory mechanisms or cortical excitatory states representative of some phases during the RRMS course that are not present in the BMS group.

Validity and reliability of the Spanish version of the DN4 (Douleur Neuropathique 4 questions) questionnaire for differential diagnosis of pain syndromes associated to a neuropathic or somatic component

BACKGROUND This study assesses the validity and reliability of the Spanish version of DN4 questionnaire as a tool for differential diagnosis of pain syndromes associated to a neuropathic (NP) or somatic component (non-neuropathic pain, NNP). METHODS A study was conducted consisting of two phases: cultural adaptation into the Spanish language by means of conceptual equivalence, including forward and backward translations in duplicate and cognitive debriefing, and testing of psychometric properties in patients with NP (peripheral, central and mixed) and NNP. The analysis of psychometric properties included reliability (internal consistency, inter-rater agreement and test-retest reliability) and validity (ROC curve analysis, agreement with the reference diagnosis and determination of sensitivity, specificity, and positive and negative predictive values in different subsamples according to type of NP). RESULTS A sample of 164 subjects (99 women, 60.4%; age: 60.4 +/- 16.0 years), 94 (57.3%) with NP (36 with peripheral, 32 with central, and 26 with mixed pain) and 70 with NNP was enrolled. The questionnaire was reliable [Cronbach's alpha coefficient: 0.71, inter-rater agreement coefficient: 0.80 (0.71-0.89), and test-retest intra-class correlation coefficient: 0.95 (0.92-0.97)] and valid for a cut-off value > or = 4 points, which was the best value to discriminate between NP and NNP subjects. DISCUSSION This study, representing the first validation of the DN4 questionnaire into another language different than the original, not only supported its high discriminatory value for identification of neuropathic pain, but also provided supplemental psychometric validation (i.e. test-retest reliability, influence of educational level and pain intensity) and showed its validity in mixed pain syndromes.

Effectiveness and costs of phototest in dementia and cognitive impairment screening

BACKGROUND To assess and compare the effectiveness and costs of Phototest, Mini Mental State Examination (MMSE), and Memory Impairment Screen (MIS) to screen for dementia (DEM) and cognitive impairment (CI). METHODS A phase III study was conducted over one year in consecutive patients with suspicion of CI or DEM at four Primary Care (PC) centers. After undergoing all screening tests at the PC center, participants were extensively evaluated by researchers blinded to screening test results in a Cognitive-Behavioral Neurology Unit (CBNU). The gold standard diagnosis was established by consensus of expert neurologists. Effectiveness was assessed by the proportion of correct diagnoses (diagnostic accuracy [DA]) and by the kappa index of concordance between test results and gold standard diagnoses. Costs were based on public prices and hospital accounts. RESULTS The study included 140 subjects (48 with DEM, 37 with CI without DEM, and 55 without CI). The MIS could not be applied to 23 illiterate subjects (16.4%). For DEM, the maximum effectiveness of the MMSE was obtained with different cutoff points as a function of educational level [k = 0.31 (95% Confidence interval [95%CI], 0.19-0.43), DA = 0.60 (95%CI, 0.52-0.68)], and that of the MIS with a cutoff of 3/4 [k = 0.63 (95%CI, 0.48-0.78), DA = 0.83 (95%CI, 0.80-0.92)]. Effectiveness of the Phototest [k = 0.71 (95%CI, 0.59-0.83), DA = 0.87 (95%CI, 0.80-0.92)] was similar to that of the MIS and higher than that of the MMSE. Costs were higher with MMSE (275.9 ± 193.3€ [mean ± sd euros]) than with Phototest (208.2 ± 196.8€) or MIS (201.3 ± 193.4€), whose costs did not significantly differ. For CI, the effectiveness did not significantly differ between MIS [k = 0.59 (95%CI, 0.45-0.74), DA = 0.79 (95%CI, 0.64-0.97)] and Phototest [k = 0.58 (95%CI, 0.45-0.74), DA = 0.78 (95%CI, 0.64-0.95)] and was lowest for the MMSE [k = 0.27 (95%CI, 0.09-0.45), DA = 0.69 (95%CI, 0.56-0.84)]. Costs were higher for MMSE (393.4 ± 121.8€) than for Phototest (287.0 ± 197.4€) or MIS (300.1 ± 165.6€), whose costs did not significantly differ. CONCLUSION MMSE is not an effective instrument in our setting. For both DEM and CI, the Phototest and MIS are more effective and less costly, with no difference between them. However, MIS could not be applied to the appreciable percentage of our population who were illiterate.

Análisis del patrón de consumo de cánnabis en estudiantes universitarios

Se analiza el patrón de consumo de cannabis en una muestrade 580 jóvenes universitarios (88.4% mujeres, edad media21.4 años). Si bien se observa que proporcionalmente máshombres que mujeres consumen habitualmente cannabis, lamagnitud de consumo de los que se reconocen usuarios essimilar en ambos sexos. Se detecta que la dependencia percibidaal cannabis se incrementa en función de la magnitud de consumo.Existe una relación positiva entre consumo de tabaco yde cannabis: el 90% de los jóvenes que no ha probado nuncael tabaco tampoco ha probado nunca el cannabis, mientrasque menos del 15% de los fumadores habituales de tabaco sehallan en esa situación. Estos resultados sugieren la necesidadde abordajes conjuntos para la prevención del consumo de drogas,principalmente en lo que se refiere al tabaco y el cannabis

Validation and clinical use of the CECA, a disease-specific quality of life questionnaire for patients with anogenital Condylomata Acuminata

The aim of this validation study was to assess the measurement properties of the CECA (Spanish acronym for the Specific Questionnaire for Condylomata Acuminata) in patients with anogenital condylomas. A total of 247 patients aged > 18 years completed the questionnaire on 2 occasions as well as the Dermatology Life Quality Index (DLQI). The CECA questionnaire showed good internal consistency (Cronbach's alpha values of 0.86 and 0.91 in the emotional and sexual activity dimensions) and good testretest reliability (intraclass correlation coefficient 0.76 emotional dimension, 0.82 sexual activity dimension). Patients with de novo lesions and those with more extensive lesions and larger number of warts showed poorer health-related quality of life. CECA and DLQI scores correlated moderately. Patients whose lesions cleared at follow-up or with a reduction of >or= 50% showed a better improvement of health-related quality of life. The CECA questionnaire is a valid, reliable and sensitive tool for the assessment of health-related quality of life in patients with anogenital warts.
