Sintomas somatoformes em Medicina Geral e Familiar

RESUMO: Os doentes que vão à consulta com sintomas físicos para os quais o médico não encontra uma causa orgânica, são frequentes na Medicina Geral e Familiar, embora não sejam específicos, e são o objecto de estudo do presente trabalho. Não deixar uma doença por diagnosticar (erro de tipo II) sem contudo rotular pessoas saudáveis como doentes (erro de tipo I) é um dos mais difíceis problemas da prática clínica diária e para o qual não existe uma orientação infalível e não é previsível que alguma vez venha a existir. Mas se o diagnóstico de doença ou não-doença é difícil, o tratamento dos que não tem doença, embora com sofrimento, também não é mais fácil, sobretudo, se estivermos conscientes do sofrimento que determina a medicalização e a iatrogenia. O presente trabalho está estruturado em 3 partes. Na primeira parte descrevemos a nossa visão integrada do que apreendemos da leitura da literatura publicada e à qual tivemos acesso. À semelhança do que se verifica na maioria das áreas da Medicina esta é também uma em que o conhecimento cresce a ritmo exponencial. No entanto, à falta de conceitos precisos e de definições consensuais sucede um conhecimento, por vezes, pouco consistente, tanto mais que estamos na fronteira entre a cultura leiga e a cultura erudita médica em que os significados devem, a todo o momento, ser validados. Fizemos uma revisão sobre as definições do que está em questão, sobre o que se sabe sobre a frequência dos sintomas físicos na população, quantos recorrem aos serviços de saúde e o que lhes é feito. Passámos por uma revisão da fisiologia destes sintomas e algumas explicações fisiopatológicas para terminarmos sobre o que os doentes pensam sobre os seus sintomas e os cuidados que recebem e o que os profissionais pensam sobre estes doentes. Esta parte termina com uma revisão das propostas de abordagem para este tipo de doentes. Na segunda parte, descrevemos os estudos empíricos focados no problema dos pacientes com sintomas físicos mas sem evidência de doença orgânica. Começa por uma apresentação dos aspectos processuais e metodológicos dos estudos realizados, mais especificamente, de dois estudos quantitativos e um qualitativo. No primeiro estudo pretendeu-se avaliar quais são os sintomas físicos e a sua frequência na população em geral e a frequência de pacientes que procuram (ou não) os serviços de saúde tendo como motivo este tipo de sintomas. O objectivo deste estudo é contribuir para a demonstração que este tipo de sintomas faz parte da vida do dia-a-dia e que, na maioria das vezes, só por si não significa doença, sem contudo negar que representa sofrimento, por vezes até maior do que quando há patologia orgânica. Se no primeiro estudo era demonstrar que os sintomas físicos são frequentes na população, no segundo estudo o objectivo é demonstrar que pacientes com este tipo de sintomas são igualmente frequentes e que o tipo de sintomas apresentados na consulta não difere dos referidos pela população em geral. Pretendia-se ainda saber o que é feito ou proposto pelo médico a estes doentes e se estes doentes traziam ou não, junto com os sintomas, ideias explicativas para os mesmos. Finalmente e não menos importante, é avaliar o grau de fidedignidade do diagnóstico de sintoma somatoforme, chamando assim ao sintoma físico que foi “levado” à consulta e que o médico diagnosticou como não tendo causa orgânica. O terceiro estudo parte do conhecimento adquirido que a Medicina tem muitas respostas para este problema, mas poucas que se possam considerar satisfatórias se usadas isoladamente. Que a maioria das soluções é procurada entre a cultura médica e num paradigma reducionista de separação mente-corpo. Contudo, se o sintoma é “construído” pelo doente, se o principal problema não está no sintoma mas na forma como o paciente o vê, então pareceu-nos lógico que a solução também tem que passar por integrarmos no plano de abordagem o que o doente entende ser melhor para si. Nesta sequência, entrevistaram-se alguns doentes cujo diagnóstico de sintomas somatoformes estava demonstrado pelo teste do tempo. Por isso, entrevistaram-se doentes que já tinham ido à consulta de MGF há mais de 6 meses por sintomas somatoformes e, na data da entrevista, o diagnóstico se mantinha inalterado, independentemente da sua evolução. As entrevistas visaram conhecer as ideias dos doentes sobre o que as motivou a procurarem a consulta, o que pensavam da forma como foram cuidados e que ideias tinham sobre o que os profissionais de saúde devem fazer para os ajudar a restabelecer o equilíbrio com o seu ambiente evitando a medicalização, a iatrogenia e a evolução para a cronicidade. Na terceira parte, discutem-se e integram-se os resultados encontrados no conhecimento previamente existente. Tenta-se teorizar, fazer doutrina sobre o tema e contribuir para abordagens terapêuticas mais personalizadas, abrangentes, variadas e multimodais, baseadas sempre no método clínico centrado no paciente, ou de modo menos correcto mas enfático, baseadas no método centrado na relação. Apresentam-se algumas hipóteses de trabalhos futuros sobre o tema e, sobretudo, esperamos ter contribuído para o reconhecimento da necessidade de a comunicação médico-doente ser uma aprendizagem transversal a todos os profissionais de saúde e ao longo da vida, com a ideia que é sempre possível fazer melhor, caso contrário tenderemos, inexoravelmente, a fazer cada vez pior.-----------ABSTRACT: Patients who go to consultation with physical symptoms, for which the doctor does not find an organic cause, are the subject of the present study. They are common in family medicine, although not specific. Do not let an undiagnosed disease (type II error), but without labeling healthy people as patients with disease (type I error) is one of the most difficult problems in clinical practice and for which doesn’t exist an infallible guide and it is unlikely that any since coming into existence. But, if the diagnosis of disease or non-disease is difficult, the treatment of those who do not have the disease, though suffering, it is not easy, especially if we are aware of the suffering that medicalization and iatrogenic determines. This work is structured in three parts. In the first part we describe our integrated view of what we grasp from reading the published literature and to which we had access. Similar to that found in most areas of medicine, this is also one in which knowledge grows exponentially. However, the absence of precise concepts and consensual definitions determines an inconsistent knowledge, especially because we're on the border between secular culture and medical culture where, at all times, the meaning must be validated. We did a review on the definitions of what is at issue, what is known about the frequency of physical symptoms in the population, how many use the services of health and what they receive as care. We went through a review of the physiology of these symptoms and some pathophysiological explanations, to finish on what patients think about their symptoms and how they perceived the care they received and, finally, what professionals think about these patients. This part ends with a review of the approaches proposed for such patients. In the second part, we describe the empirical studies focused on the problem of patients with physical symptoms but no evidence of organic disease. Begins with a presentation of the procedural and methodological aspects of studies, more specifically, two quantitative and one qualitative. The first study sought to assess which are the physical symptoms, their incidence in the general population and the frequency they seek (or not) health services on behalf of those symptoms. The aim behind this study was to contribute to the demonstration that this type of symptoms is part of life's day-to-day and that, in most cases, does not represent disease by itself, without denying that they represent suffering, sometimes even greater than when there are organic disease. The first study endeavor to demonstrate that the physical symptoms are common in the population. The second study aspires to demonstrate that patients with such symptoms are also common and that the type of symptoms presented in the consultation does not differ from those in the general population. The aim was also to know what is done or proposed by the physician for these patients and if these patients brought or not, along with the symptoms, explanatory ideas for them. Finally and not least, it would try to assess the degree of reliability of diagnosis of somatoform symptoms, thus drawing the physical symptom that patient presents in the consultation and that the doctor diagnosed as having no organic cause. The third study starts from the acquired knowledge that medicine has many answers to this problem, but few can be considered satisfactory if used in isolation. The most solutions are sought in the medical culture and based on a reductionist paradigm of mind-body. However, if the symptom is "built" by the patient, if the main problem is not the symptom but the way the patient sees it, then it seemed logical to us that the solution must integrate the approaches that patients believes are best for them. Subsequently, a few patients, whose diagnosis of somatoform symptoms was demonstrated by the test of time, were interviewed. Therefore, patients who were interviewed had gone to the consultation of family medicine more than 6 months before for somatoform symptoms and. at the moment of the interview, the diagnosis remained unchanged, regardless of their evolution. The interviews aimed to ascertain the patients' ideas about what motivated them to seek consultation, what they thought about the care they got and which ideas they have about what health professionals should do to help these patients to re-establish equilibrium with its environment avoiding medicalization, iatrogenic effects and the evolution to chronicity. In the third section, we discuss and integrate the results found in previously existing knowledge. Attempts to theorize on the subject and contribute to more personalized treatment, comprehensive, varied and multi-modal approaches, always based on patient-centered clinical method, with emphasis on the relationship. We presents some hypotheses for future work on the subject and,above all, defend the recognition of the importance of lifelong learning communication skills for all health professionals, with the idea that we can always do better, otherwise we tend inexorably to do worse.

Life (dis)satisfaction and the decision to migrate: Evidence from Central and Eastern Europe

This paper provides empirical evidence of the impact of life satisfaction on the individual intention to migrate. The impacts of individual characteristics and of country macroeconomic variables on the intention to migrate are analyzed jointly. Differently from other studies, we allow for life satisfaction to serve as a mediator between macroeconomic variables and the intention to migrate. Using the Eurobarometer Survey for 27 Central Eastern European (CEE) and Western European (non-CEE) countries, we find that people have a higher intention to migrate when dissatisfied with life. The socio-economic variables and macroeconomic conditions have an effect on the intention to migrate indirectly through life satisfaction. The impact of life satisfaction on the intention to migrate for middle-aged individuals with past experience of migration, low level of education, and with a low or average income from urban areas is higher in CEE countries than in non-CEE countries.

Low frequency of side effects following an incidental 25 times concentrated dose of yellow fever vaccine

In August/1999, a group of 14 adults from the staff of a private hospital in Contagem -- Minas Gerais State, Brazil, received unintentionally a 25 times concentrated dose of the 17-DD yellow fever vaccine (Bio-Manguinhos), due to a mistake at the reconstitution step. All patients were clinically and laboratorially evaluated at days 5, 13 and 35 post vaccination. Frequency of side effects and clinical observations of this group of individuals were not different from the observed in recipients immunized with normal doses of the vaccine. At the second and third evaluation none of the subjects reported symptoms. None of the patients presented abnormalities at the physical examination at none of the time points and in all cases the blood examination was normal, except for a reduced number of platelets that was detected in one subject at the first and second evaluation and reverted to normal at third evaluation. At the first evaluation point, 8 subjects were serum negative and 6 serum positive for yellow fever at the plaque reduction neutralization test. In 5 subjects the observed titre was 10 times higher as the baseline of 2.36 Log10 mUI/ml. The samples collected at second and third evaluation (13th and 35th days) demonstrated that all subjects responded to the vaccination with the exception of one that did not present a positive result in any of the samples collected. This evaluation confirms the safety of the 17-DD yellow fever vaccine.

Life cycle and reproductive patterns of Triatoma rubrovaria (Blanchard, 1843) (Hemiptera: Reduviidae) under constant and fluctuating conditions of temperature and humidity

The aim of this study was to evaluate the temperature and relative humidity influence in the life cycle, mortality and fecundity patterns of Triatoma rubrovaria. Four cohorts with 60 recently laid eggs each were conformed. The cohorts were divided into two groups. In the controlled conditions group insects were maintained in a dark climatic chamber under constant temperature and humidity, whereas triatomines of the ambiental temperature group were maintained at room temperature. Average incubation time was 15.6 days in the controlled conditions group and 19.1 days in the ambiental temperature. In group controlled conditions the time from egg to adult development lasted 10 months while group ambiental temperature took four months longer. Egg eclosion rate was 99.1% and 98.3% in controlled conditions and ambiental temperature, respectively. Total nymphal mortality in controlled conditions was 52.6% whereas in ambiental temperature was 51.8%. Mean number of eggs/female was 817.6 controlled conditions and 837.1 ambiental temperature. Fluctuating temperature and humidity promoted changes in the life cycle duration and in the reproductive performance of this species, although not in the species mortality.
