RESUMO: Objectivo: O exercício tem sido identificado como um factor de promoção da qualidade de vida em mulheres submetidas a cirurgia por cancro de mama. Mas os níveis de actividade física tendem a reduzir após o diagnóstico de cancro de mama e a manterem-se baixos após fim dos tratamentos. O objectivo deste estudo é verificar se um programa de exercício físico supervisionado, associado a estratégias motivacionais em mulheres submetidas a cirurgia por cancro da mama e que mantêm a intervenção usual praticada, é mais efectivo no aumento dos níveis de actividade física, na redução do índice de massa corporal e na melhoria da qualidade de vida, do que o tratamento usualmente praticado. Metodologia: Trata-se de um estudo piloto experimental, aleatorizado e controlado. Cumpriram os critérios de inclusão no estudo 37 utentes submetidas a cirurgia por cancro de mama no Hospital Fernando Fonseca, Amadora, e submetidos à intervenção usual da fisioterapia. Foram aleatoriamente distribuídas pelos grupos experimental (n=19) e de controlo (n=18). O contacto telefónico foi feito por um elemento externo, cego em relação à distribuição dos sujeitos. Alguns elementos desistiram ou não puderam participar no estudo. O número de sujeitos final foi de 11 para o grupo experimental e de 10 para o grupo de controlo, idênticos na média de idades. Todos os sujeitos mantiveram a intervenção usual da fisioterapia. Os sujeitos do grupo experimental foram ainda submetidos ao programa de exercício e promoção da actividade física. Todo o grupo foi avaliado no início do programa, no final do mesmo (12 semanas) e após 6 meses de follow-up, nos seguintes indicadores: nível de actividade física, pelo International Physical Activity Questionnaire (IPAQ), índice de massa corporal e qualidade de vida, pelos questionários: European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) e Supplementary Questionnaire Breast Cancer Module (QLQ-BR23). Resultados: O programa implementado demonstrou-se efectivo no aumento dos níveis de actividade física (p=0,017) e na qualidade de vida associada ao estado funcional (p=0,016) e ao estado de saúde global auto-percepcionado (p=0,030) no final do programa. Foi ainda possível identificar resultados positivos noutras variáveis estudadas, como por exemplo a fadiga auto-reportada, mas que não se demonstraram estatisticamente significativos, facto que pode atribuir-se à reduzida dimensão da amostra. Conclusões: Apesar de algumas limitações, este estudo é de grande a importância para a comunidade científica preocupada com crescente problemática do cancro de mama. Mais uma vez se demonstra que o exercício físico é uma estratégia importante para a melhoria do estado de saúde de pacientes confrontados com doença. Esta comprovação é de grande interesse para os profissionais de saúde e particularmente para os fisioterapeutas dedicados à promoção da saúde nesta população.---------------------ABSTRACT: Purpose: Exercise has been identified as a quality of life promoting factor, amongst women after breast cancer surgery. But the physical activity levels reduce significantly after a diagnosis of breast cancer and remain low after treatment is completed. The aim of this study is to determine whether a supervised group exercise program allied to motivating strategies in women after breast cancer surgery in conjunction with standard treatment, is more effective in improving physical activity levels, reducing body mass index and promoting quality of life, than standard treatment on its own. Methods: This is a pilot randomized controlled trial. Thirty-seven women, submitted to breast cancer surgery in the Hospital Fernando Fonseca, Amadora, and submitted to standard physiotherapy intervention, completed the inclusion criteria. They were randomly allocated into intervention group (n=19) and control group (n=18). The telephone contact was done by an external element, blind to the subjects’ allocation. Some elements declined or could not participate. The final intervention group was n=11 and the control n=10, similar in age. All subjects maintained the standard physiotherapy intervention. The experimental group was submitted to the exercise and health promotion program. The complete group was evaluated in the beginning of the program, at the final (after 12 weeks) and after 6 months follow-up, using as outcomes: physical activity index with the international Physical Activity Questionnaire (IPAQ), the body mass index and quality of life using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and Supplementary Questionnaire Breast Cancer Module (QLQBR23). Results: The studied program demonstrated to be effective in improving the physical activity index (p=0,017) and quality of live related to physical functioning (p=0,016) and to global health status (p=0,030) at the end of the program. It was possible to find positive results in some other outcomes, such as fatigue, although the differences were not statistically significant. We believe that these results can be attributed to the small sample size. Conclusions: Although we can identify some methodological constrains, this is a very important study for scientific community working on the breast cancer subject. Once more, exercise was identified as an important strategy to improve global heath status in breast cancer patients. This represents an important contribution to the health professionals and mostly for physiotherapists working on health promotion subject.

RESUMO - Na radiologia de intervenção, e concretamente em ortopedia, os raios X são intensamente utilizados permitindo a visualização de diversas técnicas de intervenção cirúrgica. Do ponto de vista médico as vantagens dessa prática são enormes, contudo, os profissionais de saúde envolvidos são susceptíveis de estarem expostos a valores de dose de radiação que significam a sua classificação como trabalhadores expostos. O presente estudo realizou-se num hospital e teve como objectivo obter uma estimativa das doses envolvidas em ortopedia de intervenção, utilizando várias metodologias experimentais para caracterização do campo de radiação primário e secundário. Observaram-se distintos níveis de dose de acordo com a zona anatómica exposta à radiação X: (i) gónadas — 0,02 a 3 mGy/h; (ii) cristalino — 0,06 a 1 mGy/h e (iii) mãos — 0,6 mGy/h. Tais resultados evidenciam uma clara necessidade de utilização de equipamentos de protecção e de vigilância dosimétrica pelos profissionais de saúde envolvidos no acto cirúrgico.--------------------------ABSTRACT - In intervention radiology, and more specifically in orthopaedics, X-rays are intensely used allowing the visualization of many acts of clinical intervention. From a clinical perspective, the advantages of that practice are significant; however, involved health care professionals are susceptible of being exposed to radiation dose values that mean their classification as exposed workers. The present study, performed in a hospital, aimed to obtain an estimation of the doses involved in intervention orthopaedics through several experimental methodologies in order to characterise the primary and the secondary radiation fields. Different levels of dose were observed according to the anatomic area exposed to X radiation: (i) gonads — 0.02 a 3 mGy/h; (ii) crystalline lens — 0.06 a 1 mGy/h e (iii) hands – 0.6 mGy/h. Such results denote a clear need of protection equipment use and of dosimetric surveillance by the health

AIMS: Evaluation of thymectomy cases between 1990-2003, in a General Surgery Department. Evaluation of the therapeutic efficacy in Miastenia Gravis patients. PATIENTS AND METHODS: Retrospective study based on evaluation of data from Serviço de Cirurgia, Neurologia and Consult de Neurology processes, between 1990-2003, of 15 patients submitted to total thymectomy. RESULTS: 15 patients, aged 17 to 72, 11 female and 4 male. Miastenia Gravis was the main indication for surgery, for uncontrollable symptoms or suspicion of thymoma. In patients with myasthenia, surgery was accomplish after compensation of symptoms. There weren't post-surgery complications. Pathology were divided in thymic hyperplasia and thymoma. Miastenia patients have there symptoms diminished or stable with reduction or cessation of medical therapy. CONCLUSIONS: Miastenia was the most frequent indication for thymectomy. Surgery was good results, with low morbimortality, as long as the protocols are respected.

Purpose: To assess the results obtained in very high-risk patients, which are those patients with an EUROSCORE greater than 13 points. Material and methods: From September 2001 to September 2003, thirty-three very high-risk patients were operated on in our department, which represents 1.6% of all the surgical activity during that period of time, being 17 male and 16 female, with an average of 69 years old (maximum 86 and minimum 32). Diagnosis includes: post infarction CIV 5, coronary insufficiency 11, aortic dissection 3, mitral prosthesis 3, valvular disease 9, aortic prosthesis disfunction 2. Fifteen patients underwent an emergency procedure, 12 were urgent and the remaining 6 were electively operated on. Results: Overall post-operative mortality was 12 patients (36%), being 6 emergent, 5 urgent and 1 elective patient. Patients who survived the operation had longer intensive care and hospital admission periods, which will be analyzed in detail. Conclusion: Surgery can be justified in very high risk patients. Despite the high perioperative mortality and longer periods of hospital stay, they will be otherwise condamned to death, if surgery would not be performed.

In this paper the authors proceed to a revision of the three main methods employed for cerebral protection in aortic arch surgery, namely the deep hypothermia and total circulatory arrest, the retrograde cerebral perfusion and the selective anterograde cerebral perfusion. After a deep analysis on their advantages and disadvantages, they proposed the utilization of an association of methods (integrated approach) that has proved to be extremely well succeed in their clinical practice, specially in high-risks patients.

Traumatic lesions of the femoral veins during varicose veins surgery are very uncommon and they raise several therapeutic difficulties. They occur in 1/1000 cases of varicose veins operated. The authors describe four cases of lesions of this type that were seen and treated for the last six years, probably because there was an increase in the number of varicose veins operated on in the Lisbon area. The authors discuss the surgical options and they concluded that these complications can be minimized with good anatomical and surgical skills, specially of the saphenous-femoral and saphenous-popliteal junctions.

BACKGROUND: Valve surgery in children is aimed at restoring correct hemodynamics with few reoperations and limited resort to prostheses, which would imply early deterioration or definitive hypocoagulation. OBJECTIVES: Report a series of paediatric pts with acquired mitral valve disease, mostly due to rheumatic disease, in whom it was possible, for the great majority, to repair the damaged valve. DEMOGRAPHICS: Fifty children with predominant mitral valve disease, 47 rheumatic (94%) and 3 after endocarditis were consequently operated by the same surgical team over the last five years. Ages were 12.5+/-3.1 yrs and weights 33.2+/-8.4 Kg, 30 pts presented with predominant mitral regurgitation and 20 pts had significant stenosis. In 8 pts there also moderate to severe aortic regurgitation and in 2 pts severe tricuspid regurgitation was present. Patients were not operated during the acute phase of the disease. Five pts were reoperations and from those, all but one received mechanical prosthesis. RESULTS: In all operations the intention was to repair the mitral valve. In 46 pts complex mitral valvuloplasties were performed extended comissurotomies, shortening of chordae, chordal replacement with PTFE, and reconstruction of valve leaflefts by direct patching or pericardial extension of the retracted posterior leaflet (78.2% cases), plus reshaping of the annulus by using a fixed prosthetic CE ring (sizes 26 to 32) in every case. Ring sizes correlated poorly with body weights, but correlation was close and positive for the use of pericardial advancement of the posterior leaflet (p<0.01). There was no operative mortality, but one pt died early from sepsis and there was no late mortality. Maximum follow up extends now to 50 months (median 28 months) and functional evaluation, at latest follow up, as assessed by Doppler Echocardiography, showed residual mitral regurgitation, mild-moderate in 4 pts and LA-LV gradients mild in 5 and moderate in 2 pts. NYHA functional class, at present follow-up is class I for 43 pts (88%) and class II in the remaining 6 pts. Along the follow-up period 2 pts had to be reoperated for early repair failures and other three for late failures, presently freedom for reoperation is 91.8% at 5 years. CONCLUSIONS: Mitral valve repair in children with rheumatic lesions can be achieved for the great majority of cases by using different techniques. Pericardial extension of the retracted posterior leaflet allowed the use of a bigger size prosthetic ring. Intermediate functional results are good with fair functional classes and few reoperations but follow-up is short and does not allow us to draw conclusions about the long-term results of the repair in these rheumatic patients.

A 75-year old female patient, with previous inferior acute myocardial infarction (AMI) in December 2000, was admitted in April 2001 with angina and heart failure. Transthoracic echocardiography (TTE) was suggestive of a postero-inferior pseudoaneurysm (PA) of the left ventricle (LV), with 61x49 mm. of size and mitral regurgitation. Cardiac catheterization was suspected of a PA of the LV and revealed a three vessels coronary artery disease. On 20th April she was submitted to cardiac surgery with resection of a large LV aneurysm (AN) and triple coronary artery bypass surgery. Afterwards, she was on NYHA class III and subsequent TTE and transesophagic echocardiography (TEE) were suggestive of a 90x60 mm LV posterior PA (confirmed by nuclear magnetic resonance) and severe mitral regurgitation, with good LV systolic function. She underwent a new cardiac surgery on 31st May 2002, with resuturing of the LV postero-inferior wall patch and removal of the PA. The patient is in good condition and on NYHA functional class I-II.

A utilização do catéter de Foley na prática da algaliação está desde há muito definida. Os autores têm, no entanto, utilizado o catéter Foley em diversas situações de recurso, no âmbito da cirurgia cardíaca. A utilização deste método de enorme simplicidade e de muito baixo custo representa um verdadeiro "ovo de Colombo" e deve fazer parte do armentarium cirúrgico alternativo de cada um de nós. Descreve-se o uso do catéter Foley, como alternativa de recurso, nas seguintes situações: 1. Laceração de uma cavidade cardíaca na re-esternotomia com hemorragia catastrófica; 2. Realização de anastomoses proximais em aortas que não devem ou podem ser clampadas (calcificações extensas); 3. Realização de anastomoses de condutos ventrículo-direito artéria pulmonar com o coração a bater.

A Nocardia é responsável por diversos tipos de infecção quer em receptores imunocompetentes, quer imunocomprometidos e pode afectar qualquer órgão. A endocardite a Nocardia spp é muito rara e tem mau prognóstico. Segundo o nosso conhecimento e após revisão da literatura, foram reportados apenas 12 casos de endocardite a Nocardia, a maioria tratada com substituição valvular. Reportamos o primeiro caso descrito em Portugal de endocardite protésica a Nocardia, tratado com sucesso apenas com terapêutica antimicrobiana (trimetoprimsulfametoxazol), sem necessidade de substituição valvular.

A cirurgia dos tumores do pâncreas continua a ser marcada pela pobreza dos resultados obtidos. No caso dos tumores localmente invasivos, os doentes são habitualmente sujeitos a uma mera cirurgia de derivação, com escassa sobrevivência e má qualidade de vida. Os autores operaram sete doentes com tumores do pâncreas localmente invasivos, sujeitos a cirurgia de ressecção radical, com bons resultados. É apresentada uma técnica original de reconstrução da circulação arterial hepática.

Os tumores do cólon e recto com invasão locoregional ou metastizados constituem situações clínicas graves, com escassa esperança de sobrevivência. A cirurgia oncológica radical alargada constitui a única solução potencialmente curativa ou que pode proporcionar sobrevidas mais longas. Foram operados 32 doentes portadores de tumores colo-rectais metastizados ou com invasão locoregional, quer primitivos quer recidivados, tendo sido obtidas sobrevidas até aos sete anos, com boa qualidade de vida.

A trissomia 18 caracteriza-se por múltiplas anomalias, incluindo doença cardíaca em 60 a 90% dos casos e elevada mortalidade. O mau prognóstico global, conduz habitualmente a uma politica de “cuidados mínimos” mas, paliar, é também nestas situações, um imperativo ético. Descreve-se o caso de uma recém-nascida sem diagnóstico pré natal, mas com confirmação por cariotipo, com cardiopatia, que condicionou insuficiência cardíaca congestiva e angústia respiratória crescente, inviabilizando alta hospitalar, como era desejo da família. Após consenso entre os pais e o corpo clínico responsável, foi decidida intervenção cirúrgica cardíaca paliativa, que possibilitou melhoria clínica e alta para o domicílio. Os autores defendem que a cirurgia cardíaca pode ser uma atitude a considerar em casos de trissomia 18, pois pode aliviar o sofrimento.
