Participación social en salud: conceptos de usuarios, líderes comunitarios, gestores y formuladores de políticas en Colombia. Una mirada cualitativa.

BACKGROUND Health sector reforms taking place in Colombia during the Nineties included policies to promote social participation in the health system, which is considered essential to its functioning. The aim of this article is to analyse the meaning and the significance of participation in health for the different social actors involved in implementing policies in Colombia. METHODS A qualitative, descriptive, exploratory study was carried out using focal groups (FG) and semi-structured individual interviews (I) of the different social actors: 210 users (FG), 40 community leaders (FG), 3 policy makers (E) and 36 healthcare professionals (E). A carried out analysis was content up of the contents. The study area corresponded to the municipalities of Tulua and Palmira in Colombia. RESULTS The concept of participation was interpreted differently depending on the actor studied: for users and leaders the concept referred to contributing ideas, presence in social spaces, solidarity and frequently, and use of the health services. Healthcare professionals considered the activities carried out by institutions together with the community as social participation, the use of services and affiliation to the health system. Policy markers considered participation to concern evaluation and control of the health services by the community, to improve its quality. CONCLUSIONS The different concepts of participation reveal dif ferences between the content of the policy and how it is understood and interpreted by the different social actors in their interaction with the health services. These different perspectives must be taken into account to develop a link between society and the health services.

Revisión de los trabajos publicados sobre promoción de la salud en jóvenes españoles.

The objective of this study is to review the health promotion interventions on spanish youths published in Spanish in the 1995-2000 period and to describe them in accordance with the scope within which they have been carried out, the topics addressed, the methodology, the evaluation design used and the results obtained. Two hundred and fourteen intervention were identified. Illegal drugs were the topic on which the largest number of interventions were focused (29.8%), followed by alcohol (15.9%), the risk-related sexual behaviours (14.6%) and leisure time (12.6%). The activities carried out most often were: participation-based educational methods (30.7%), explanatory education methods (11.5%) and the preparation of educational materials (11%). In 80.8% of the cases, some evaluation of the health promotion activities was found. The type of evaluation employed most often was the process evaluation (73.7%), and the medium-long term results evaluation being those employed the least (2.2%). The evaluation methodologies used most often were questionnaires (28.2%). A combination of qualitative and quantitative methods was employed in 13.2% of the cases. The four interventions in which the medium-long term impact was gauged had the purpose of preventing and reducing cigarette smoking and/or drinking and or marijuana smoking, all of these initiatives achieving a reduction in cigarette smoking. In conclusion, it seems necessary to improve the design of the evaluations of the health promotion initiatives addressed to young people in Spain and to increase the dissemination of the same by way of their publication.

El proyecto EMECAM: Estudio Multicéntrico Español sobre la Relación entre la Contaminación Atmosférica y la Mortalidad. Antecedentes, participantes, objetivos y métodología.

In recent years, a growing number of studies suggests that increases in air pollution levels may have short-term impact on human health, even at pollution levels similar to or lower than those which have been considered to be safe to date. The different methodological approaches and the varying analysis techniques employed have made it difficult to make a direct comparison among all of the findings, preventing any clear conclusions from being drawn. This has led to multicenter projects such as the APHEA (Short-Term Impact of Air Pollution on Health. A European Approach) within a European Scope. The EMECAM Project falls within the context of the aforesaid multicenter studies and has a wide-ranging projection nationwide within Spain. Fourteen (14) cities throughout Spain were included in this Project (Barcelona, Metropolitan Area of Bilbao, Cartagena, Castellón, Gijón, Huelva, Madrid, Pamplona, Seville, Oviedo, Valencia, Vigo, Vitoria and Saragossa) representing different sociodemographic, climate and environmental situations, adding up to a total of nearly nine million inhabitants. The objective of the EMECAM project is that to asses the short-term impact of air pollution throughout all of the participating cities on the mortality for all causes, on the population and on individuals over age 70, for respiratory and cardiovascular design causes. For this purpose, with an ecological, the time series data analyzed taking the daily deaths, pollutants, temperature data and other factors taken from records kept by public institutions. The period of time throughout which this study was conducted, although not exactly the same for all of the cities involved, runs in all cases from 1990 to 1996. The degree of relationship measured by means of an autoregressive Poisson regression. In the future, the results of each city will be combined by means of a meta-analysis.

Results of a combination of bleomycin and triamcinolone acetonide in the treatment of keloids and hypertrophic scars.

While treatment of keloids and hypertrophic scars normally shows modest results, we found that treatment with bleomycin was more promising. The present study was divided into two parts. In the first part the aim was to show the results using a combination of bleomycin and triamcinolone acetonide per cm2 (BTA). In the second part the objective was to determine the response to both drugs in large keloids that were divided into 1 cm2 squares, treating each square with the dose previously used. In the first part of the study, the clinical response of 37 keloids ranging from 0.3 to 1.8 cm2 treated with BTA were followed up over a period of 1- 2 years. 0.375 IU bleomycin and 4 mg triamcinolone acetonide were injected every 3 months. In the second part of the study we reviewed the clinical response in six patients with large keloids. The monthly dose administered never exceeded 3 IU of bleomycin. The first study showed 36 keloids (97.29%) softening after the first dose. In the second study, 5 showed different responses (the response was complete in the four smaller keloids). The largest keloid needed 9 doses to achieve an improvement of 70%. In conclusion, combined treatment with 0.375 IU of bleomycin and 4mg of triamcinolone acetonide to 1 cm2 was considered to be an acceptable procedure for the treatment of keloids. The best results were obtained in keloids over 1 cm2 or when divided into 1 cm2 square areas. Larger series need to be performed in order to confirm these results..

Efectividad comparativa del seguimiento remoto a personas con marcapasos cardíacos frente al convencional: calidad de vida a los 6 meses.

BACKGROUND The use of remote follow-up (RF) of people with pacemakers (PM) is limited in comparison to the hospital modality (HS), being still poor the scientific evidence that shows their comparative effectiveness. The aim of this study was to compare the quality of life in individuals with different modalities of follow-up. METHODS Controlled, not randomized nor masked clinical trial, with data collection at pre and post-implantation of pacemakers during the 6 months follow-up. All patients over 18 years-old who were implanted a PM during the study period were selected (n = 83), and they were assigned to RF (n = 30) or HF (n = 53) groups according to their personal characteristics and patient's preferences. Baseline characteristics and number of visits to the hospital were analysed, the EuroQol-5D (EQ5D) questionnaire was administered to evaluate the health-related quality of life, and Duke Activity Status Index (DASI) to assess the functional capacity. RESULTS There were no significant differences between both groups in relation to the baseline analysis, EQ5D (RF:0.7299; HF:0.6769) and DASI (RF:21.41; HF:19.99). At 6 months the quality of life was improved in both groups (EQ5D RF:0.8613; HF:0.8175; p = 0,439) still without significant differences between them. DASI score was similar to baseline (20.51 vs 21.80). RF group performed less transmissions/visits per patient (1.57) than hospital group (1.96; relative reduction 31%; p = 0.015). CONCLUSIONS Remote follow-up of people with pacemakers might be considered as an equivalent option to the hospital follow-up in relation to the quality of life and it reduces the number of hospital visits.

Estudio de las subpoblaciones linfocitarias y secreción intratecal en pacientes con esclerosis múltiple defnida

Multiple sclerosis is an infammatory demyelinating autoimmune disease that affects the brain and spinal cord. The aim of the study was to quantify lym-phocyte subpopulations in cerebrospinal fuid and blood of patients diagnosed with multiple sclerosis and in patients whit degenerative diseases not (control) in order to fnd some relationships between them that make it possible to differentiate the immune status of patients in each group. This work was jointly carried out with Hospital Universitario Virgen Macarena in Seville during 2008, 2009 and 2010. It is a descriptive, transversal and cohort study. The selected population is composed of 142 subjects who were subjected to lumbar puncture and a blood sample. Group 1 (n=70), control, Group 2 (n=53), patients with relapsing remitting multiple sclerosis, Group 3 (n=5), patients with primary type progressive multiple sclerosis, and Group 4 (n=14) patients with isolated neurological syndrome. The results show an increase in CSF B cells in MS patients suggesting an increase in focal infammatory activity in the CNS. Regarding NKCD8, reduced total levels of NK and NKCD8 regard-ing controls were observed, and it showed an increased IgG index value in patients with RRMS.

O to Z flaps in facial reconstructions.

Local flaps are the standard procedure to reconstruct facial defects. As it occurs in any surgical procedure, the incision should be planned so that scars are located in the minimum skin tension lines. We report two cases of O to Z flaps in the supra and infraciliary regions. One of them is a hatchet flap.

A non-invasive assessment of hepatic glycogen kinetics and post-absorptive gluconeogenesis in man.

A novel approach to the study of hepatic glycogen kinetics and fractional gluconeogenesis in vivo is described. Ten healthy female subjects were fed an iso-caloric diet containing 55% carbohydrate energy with a 13C abundance of 1.083 atom percent for a 3-day baseline period; then, a diet of similar composition, but providing carbohydrate with a 13C abundance of 1.093 atom percent was started and continued for 5 days. Resting respiratory gas exchanges, urinary nitrogen excretion, breath 13CO2 and plasma 13C glucose were measured every morning in the fasting state. The enrichment in 13C of hepatic glycogen was calculated from these measured data. 13C glycogen enrichment increased after switching to a 13C enriched carbohydrate diet, and was identical to the 13C enrichment of dietary carbohydrates after 3 days. The time required to renew 50% of hepatic glycogen, as determined from the kinetics of 13C glycogen enrichment, was 18.9 +/- 3.6 h. Fractional gluconeogenesis, as determined from the difference between the enrichments of glucose oxidized originating from hepatic glycogen and plasma glucose 13C was 50.8 +/- 5.3%. This non-invasive method will allow the study of hepatic glycogen metabolism in insulin-resistant patients.

Tools in pharmacovigilance in psychiatry: therapeutic drug monitoring, pharmacogenetic tests and drug-drug interactions databases

SUMMARYIn order to increase drug safety we must better understand how medication interacts with the body of our patients and this knowledge should be made easily available for the clinicians prescribing the medication. This thesis contributes to how the knowledge of some drug properties can increase and how to make information readily accessible for the medical professionals. Furthermore it investigates the use of Therapeutic drug monitoring, drug interaction databases and pharmacogenetic tests in pharmacovigilance.Two pharmacogenetic studies in the naturalistic setting of psychiatric in-patients clinics have been performed; one with the antidepressant mirtazapine, the other with the antipsychotic clozapine. Forty-five depressed patients have been treated with mirtazapine and were followed for 8 weeks. The therapeutic effect was as seen in other previous studies. Enantioselective analyses could confirm an influence of age, gender and smoking in the pharmacokinetics of mirtazapine; it showed a significant influence of the CYP2D6 genotype on the antidepressant effective S-enantiomer, and for the first time an influence of the CYP2B6 genotype on the plasma concentrations of the 8-OH metabolite was found. The CYP2B6*/*6 genotype was associated to better treatment response. A detailed hypothesis of the metabolic pathways of mirtazapine is proposed. In the second pharmacogenetic study, analyses of 75 schizophrenic patients treated with clozapine showed the influence of CYP450 and ABCB1 genotypes on its pharmacokinetics. For the first time we could demonstrate an in vivo effect of the CYP2C19 genotype and an influence of P-glycoprotein on the plasma concentrations of clozapine. Further we confirmed in vivo the prominent role of CYP1A2 in the metabolism of clozapine.Identifying risk factors for the occurrence of serious adverse drug reactions (SADR) would allow a more individualized and safer drug therapy. SADR are rare events and therefore difficult to study. We tested the feasibility of a nested matched case-control study to examine the influence of high drug plasma levels and CYP2D6 genotypes on the risk to experience an SADR. In our sample we compared 62 SADR cases with 82 controls; both groups were psychiatric patients from the in-patient clinic Königsfelden. Drug plasma levels of >120% of the upper recommended references could be identified as a risk factor with a statistically significant odds ratio of 3.5, a similar trend could be seen for CYP2D6 poor metaboliser. Although a matched case-control design seems a valid method, 100% matching is not easy to perform in a relative small cohort of one in-patient clinic. However, a nested case-control study is feasible.On the base of the experience gained in the AMSP+ study and the fact that we have today only sparse data indicating that routine drug plasma concentration monitoring and/or pharmacogenetic testing in psychiatry are justified to minimize the risk for ADR, we developed a test algorithm named "TDM plus" (TDM plus interaction checks plus pharmacogenetic testing).Pharmacovigilance programs such as the AMSP project (AMSP = Arzneimittelsicherheit in der Psychiatrie) survey psychiatric in-patients in order to collect SADR and to detect new safety signals. Case reports of such SADR are, although anecdotal, valuable to illustrate rare clinical events and sometimes confirm theoretical assumptions of e.g. drug interactions. Seven pharmacovigilance case reports are summarized in this thesis.To provide clinicians with meaningful information on the risk of drug combinations, during the course of this thesis the internet based drug interaction program mediQ.ch (in German) has been developed. Risk estimation is based on published clinical and pharmacological information of single drugs and alimentary products, including adverse drug reaction profiles. Information on risk factors such as renal and hepatic insufficiency and specific genotypes are given. More than 20'000 drug pairs have been described in detail. Over 2000 substances with their metabolic and transport pathways are included and all information is referenced with links to the published scientific literature or other information sources. Medical professionals of more than 100 hospitals and 300 individual practitioners do consult mediQ.ch regularly. Validations with comparisons to other drug interaction programs show good results.Finally, therapeutic drug monitoring, drug interaction programs and pharmacogenetic tests are helpful tools in pharmacovigilance and should, in absence of sufficient routine tests supporting data, be used as proposed in our TDM plus algorithm.RESUMEPour améliorer la sécurité d'emploi des médicaments il est important de mieux comprendre leurs interactions dans le corps des patients. Ensuite le clinicien qui prescrit une pharmacothérapie doit avoir un accès simple à ces informations. Entre autres, cette thèse contribue à mieux connaître les caractéristiques pharmacocinétiques de deux médicaments. Elle examine aussi l'utilisation de trois outils en pharmacovigilance : le monitorage thérapeutique des taux plasmatiques des médicaments (« therapeutic drug monitoring »), un programme informatisé d'estimation du risque de combinaisons médicamenteuses, et enfin des tests pharmacogénétiques.Deux études cliniques pharmacogénétiques ont été conduites dans le cadre habituel de clinique psychiatrique : l'une avec la mirtazapine (antidépresseur), l'autre avec la clozapine (antipsychotique). On a traité 45 patients dépressifs avec de la mirtazapine pendant 8 semaines. L'effet thérapeutique était semblable à celui des études précédentes. Nous avons confirmé l'influence de l'âge et du sexe sur la pharmacocinétique de la mirtazapine et la différence dans les concentrations plasmatiques entre fumeurs et non-fumeurs. Au moyen d'analyses énantiomères sélectives, nous avons pu montrer une influence significative du génotype CYP2D6 sur l'énantiomère S+, principalement responsable de l'effet antidépresseur. Pour la première fois, nous avons trouvé une influence du génotype CYP2B6 sur les taux plasmatiques de la 8-OH-mirtazapine. Par ailleurs, le génotype CYP2B6*6/*6 était associé à une meilleure réponse thérapeutique. Une hypothèse sur les voies métaboliques détaillées de la mirtazapine est proposée. Dans la deuxième étude, 75 patients schizophrènes traités avec de la clozapine ont été examinés pour étudier l'influence des génotypes des iso-enzymes CYP450 et de la protéine de transport ABCB1 sur la pharmacocinétique de cet antipsychotique. Pour la première fois, on a montré in vivo un effet des génotypes CYP2C19 et ABCB1 sur les taux plasmatiques de la clozapine. L'importance du CYP1A2 dans le métabolisme de la clozapine a été confirmée.L'identification de facteurs de risques dans la survenue d'effets secondaire graves permettrait une thérapie plus individualisée et plus sûre. Les effets secondaires graves sont rares. Dans une étude de faisabilité (« nested matched case-control design » = étude avec appariement) nous avons comparé des patients avec effets secondaires graves à des patients-contrôles prenant le même type de médicaments mais sans effets secondaires graves. Des taux plasmatiques supérieurs à 120% de la valeur de référence haute sont associés à un risque avec « odds ratio » significatif de 3.5. Une tendance similaire est apparue pour le génotype du CYP2D6. Le « nested matched case-control design » semble une méthode valide qui présente cependant une difficulté : trouver des patients-contrôles dans le cadre d'une seule clinique psychiatrique. Par contre la conduite d'une « nested case-control study » sans appariement est recommandable.Sur la base de notre expérience de l'étude AMSP+ et le fait que nous disposons que de peux de données justifiant des monitorings de taux plasmatiques et/ou de tests pharmacogénétiques de routine, nous avons développé un test algorithme nommé « TDMplus » (TDM + vérification d'interactions médicamenteuses + tests pharmacogénétique).Des programmes de pharmacovigilances comme celui de l'AMSP (Arzneimittelsicherheit in der Psychiatrie = pharmacovigilance en psychiatrie) collectent les effets secondaires graves chez les patients psychiatriques hospitalisés pour identifier des signaux d'alertes. La publication de certains de ces cas même anecdotiques est précieuse. Elle décrit des événements rares et quelques fois une hypothèse sur le potentiel d'une interaction médicamenteuse peut ainsi être confirmée. Sept publications de cas sont résumées ici.Dans le cadre de cette thèse, on a développé un programme informatisé sur internet (en allemand) - mediQ.ch - pour estimer le potentiel de risques d'une interaction médicamenteuse afin d'offrir en ligne ces informations utiles aux cliniciens. Les estimations de risques sont fondées sur des informations cliniques (y compris les profils d'effets secondaires) et pharmacologiques pour chaque médicament ou substance combinés. Le programme donne aussi des informations sur les facteurs de risques comme l'insuffisance rénale et hépatique et certains génotypes. Actuellement il décrit en détail les interactions potentielles de plus de 20'000 paires de médicaments, et celles de 2000 substances actives avec leurs voies de métabolisation et de transport. Chaque information mentionne sa source d'origine; un lien hypertexte permet d'y accéder. Le programme mediQ.ch est régulièrement consulté par les cliniciens de 100 hôpitaux et par 300 praticiens indépendants. Les premières validations et comparaisons avec d'autres programmes sur les interactions médicamenteuses montrent de bons résultats.En conclusion : le monitorage thérapeutique des médicaments, les programmes informatisés contenant l'information sur le potentiel d'interaction médicamenteuse et les tests pharmacogénétiques sont de précieux outils en pharmacovigilance. Nous proposons de les utiliser en respectant l'algorithme « TDM plus » que nous avons développé.

Les arènes de la normalisation internationale à l'épreuve de la participation : le projet INTERNORM

Our paper presents a pilot project (INTERNORM) funded by the University of Lausanne to support the involvement of not-for-profit organisations in international standard setting bodies such as the ISO. It analyses preliminary results on how a distinct participatory mechanism can influence the institutional environment of technical diplomacy in which ISO standards are developed. It reflects on the contribution of innovative deliberative mechanisms to democratise the field of international standardisation, largely dominated by expert knowledge and market players. It draws upon international relations literature on new institutional forms in global governance and social studies of science on participatory issues in science-society relations. The paper argues that there are significant limitations to the rise of civil society participation in such global governance mechanisms and examines several types of barriers to the involvement of not-for-profit organisations in ISO standard-setting processes. Notre communication porte sur un projet pilote (INTERNORM) financé par l'Université de Lausanne pour favoriser l'implication des acteurs associatifs dans l'élaboration des normes internationales de type ISO. Elle analyse les effets d'un dispositif participatif sur l'environnement institutionnel très particulier de la diplomatie technique ayant cours à l'ISO. Elle présente les résultats intermédiaires d'une réflexion sur l'apport de dispositifs délibératifs pour démocratiser le champ de la normalisation internationale, largement dominé par le savoir expert et les acteurs économiques. Elle situe cette réflexion au croisement des travaux de relations internationales sur les nouvelles formes institutionnelles de la gouvernance de la mondialisation et des études sociales des sciences et des techniques sur la participation dans les rapports science - société. En identifiant plusieurs registres dans lesquels situer les difficultés d'une plus grande implication des acteurs associatifs dans les procédures d'élaboration de spécifications techniques de type ISO, nous posons l'hypothèse qu'il existe d'importantes limites à l'accroissement de la dimension participative de la gouvernance globale.

Automated Segmentation of Cerebral Vasculature with Aneurysms in 3DRA and TOF-MRA using Geodesic Active Regions: an Evaluation Study

Purpose: To evaluate the suitability of an improved version of an automatic segmentation method based on geodesic active regions (GAR) for segmenting cerebral vasculature with aneurysms from 3D X-ray reconstruc-tion angiography (3DRA) and time of °ight magnetic resonance angiography (TOF-MRA) images available in the clinical routine.Methods: Three aspects of the GAR method have been improved: execution time, robustness to variability in imaging protocols and robustness to variability in image spatial resolutions. The improved GAR was retrospectively evaluated on images from patients containing intracranial aneurysms in the area of the Circle of Willis and imaged with two modalities: 3DRA and TOF-MRA. Images were obtained from two clinical centers, each using di®erent imaging equipment. Evaluation included qualitative and quantitative analyses ofthe segmentation results on 20 images from 10 patients. The gold standard was built from 660 cross-sections (33 per image) of vessels and aneurysms, manually measured by interventional neuroradiologists. GAR has also been compared to an interactive segmentation method: iso-intensity surface extraction (ISE). In addition, since patients had been imaged with the two modalities, we performed an inter-modality agreement analysis with respect to both the manual measurements and each of the two segmentation methods. Results: Both GAR and ISE di®ered from the gold standard within acceptable limits compared to the imaging resolution. GAR (ISE, respectively) had an average accuracy of 0.20 (0.24) mm for 3DRA and 0.27 (0.30) mm for TOF-MRA, and had a repeatability of 0.05 (0.20) mm. Compared to ISE, GAR had a lower qualitative error in the vessel region and a lower quantitative error in the aneurysm region. The repeatabilityof GAR was superior to manual measurements and ISE. The inter-modality agreement was similar between GAR and the manual measurements. Conclusions: The improved GAR method outperformed ISE qualitatively as well as quantitatively and is suitable for segmenting 3DRA and TOF-MRA images from clinical routine.

Conclusion : les usages possibles et contestables des normes et des institutions dans l'internationalisation des services

The conclusion of this volume on technical standards in the regulation of services reviews the authors' contributions to understanding the relation between tertiarisation, internationalisation and standardisation from three distinct perspectives : theoretical, institutional, and sectorial. It argues that conventional views on conditions for standardisation and internationalisation of service activities are overly restrictive, making them dependent on sectorial and institutional specificity. In emphasizing the possible and contestable uses of service standards, the volume opens a critical debate on service offshoring, underlining the social and historical constructions of its transnational logic.

Dimensionamento informatizado de profissionais de enfermagem: avaliação de um software

A complexidade para operacionalizar o método de dimensionamento de profissionais de enfermagem, diante das inúmeras variáveis relativas à identificação da carga de trabalho, do tempo efetivo de trabalho dos profissionais e do Índice de Segurança Técnica (IST), evidenciou a necessidade de desenvolver um software, denominado: Dimensionamento Informatizado de Profissionais de Enfermagem (DIPE). Este estudo exploratório descritivo teve como objetivo avaliar a qualidade técnica e o desempenho funcional do DIPE. Participaram como sujeitos da pesquisa dezoito avaliadores, sendo dez enfermeiros docentes ou enfermeiros gerentes de unidades de saúde hospitalar e oito especialistas em informática em saúde. A avaliação do software baseou-se na norma NBR ISO/IEC 9126-1, considerando as características funcionalidade, confiabilidade, usabilidade, eficiência e ma­nutenibilidade. A avaliação do software obteve resultados positivos, sobre os quais os avaliadores concordaram em todas as características avaliadas. As sugestões relatadas serão importantes para a proposição de melhorias e aprimoramento do DIPE.

Elaboração de diagnósticos e intervenções à luz de diferentes sistemas de classificações de enfermagem

Este estudo faz uma análise sobre o uso de diferentes sistemas de classificação e o atendimento aos padrões estabelecidos pela ISO 18.104:2003 a partir de uma situação clínica fictícia. Foram elaborados diagnósticos e intervenções de enfermagem utilizando a NANDA-I, NIC e CIPE®, e analisou-se a correspondência terminológica destes sistemas de classificação ao modelo proposto pela norma ISO 18.104:2003. Para a construção de diagnósticos de enfermagem, a NANDA-I e a CIPE® adequando-se à norma ISO 18.104:2003. Para a construção das intervenções de enfermagem, a CIPE® atende ao modelo de referência terminológica proposto pela ISO 18104:2003. Por sua vez, a NIC não propõe um modelo de referência terminológica combinatória. A unificação das terminologias de enfermagem depende da revisão, padronização e teste dessas classificações para o estabelecimento de uma linguagem comum e sólida da profissão.
