Reparação Híbrida do Arco Aórtico: Experiência Inicial do Hospital de Santa Marta

Objectives: To retrospectively review the hybrid treatment of the aortic arch with supra-aortic debranching and endo- vascular stent-graft repair in a single institution. Methods: From 2007 to 2010, all patients submitted to aortic debranching procedures were entered into a prospective database analysis. For the present study, only patients with sealing zones 0 and 1, according to the Ishimaru classification, were included. Procedure-related morbimortality was analysed for the open and endovascular procedures. Results: During the study period, we electively performed 6 total aortic debranching and 4 partial aortic debranching procedures in 10 patients. According to the etiology the indications were: 6 aortic arch aneurysms, 2 post-dissection aneu- rysms, 1 false aneurysm and 1 type I endoleak following TEVAR. The proximal sealing zone was Ishimaru zone 0 in six patients and zone 1 in four patients. The TEVAR procedure was delayed in all patients with a completion success of 80% (1 patient died from ruptured aortic aneurysm; 1 patient denied the second procedure and was lost to follow-up). The 30d mortality rate was 10% (patient mentioned above). The main morbidity was: 1 axillar venous thrombosis, 1 case of subclinical myocardial infarction, 1 case of terminal renal insufficiency and 1 case of prolonged ventilation. No permanent cerebral or peripheral neurologic deficit was noted. Conclusions: The hybrid repair of the aortic arch is a feasible and reproducible procedure, and our results are similar to the previously published series. Medium and long-term results are necessary to confirm whether the technique can be regarded as a safe alternative to open surgery in high-risk patients.

Análise biomecânica da marcha e funcionalidade em crianças com Paralisia Cerebral: efeito da intervenção da fisioterapia com facilitação em tapete rolante

Introdução: As crianças com Paralisia Cerebral evidenciam frequentemente alterações da sua funcionalidade global, evidenciadas nomeadamente na marcha. Diferentes protocolos de facilitação da marcha em tapete rolante têm vindo a ser alvo de estudos no sentido de clarificar a sua eficácia nesta população. Estes sugerem uma evolução positiva dos diferentes aspectos estudados (funcionalidade global, resistência cardiorespiratória, componentes da marcha), contudo utilizam diferentes metodologias e especificidades do protocolo, não existindo consenso acerca das melhores condições de utilização. Objectivo(s): O presente trabalho teve como objectivo principal avaliar o efeito da aplicação de um protocolo de marcha em tapete rolante (PMTR) em crianças com Paralisia Cerebral (PC) espástica, nos parâmetros biomecânicos da mesma e funcionalidade global. Métodos: Participaram no estudo 9 crianças com PC do tipo diplégico e hemiplégico inscritos na Associação de Paralisia Cerebral de Braga (APCB), com idades compreendidas entre os 3 e os 8 anos de idade. Cada criança foi avaliada antes e após a aplicação do PMTR, através da análise biomecânica da marcha (dinamometria e electromiografia de superfície), bem como da aplicação do teste de medida da função motora (TMFM). A amostra foi dividida em dois grupos – grupo sujeito ao protocolo de marcha em tapete rolante (GPMTR) (n=5) e grupo controlo (GC) (n=4). O protocolo em tapete rolante foi incluído nas sessões de intervenção de fisioterapia, com uma frequência semanal de 2 a 3 vezes por semana, durante um período de 10 semanas consecutivas, após o qual foram repetidas as avaliações iniciais. Resultados: A análise dos resultados permitiu verificar evoluções no GPMTR ao nível do score total da TMFM e especialmente na dimensão E, o que revelou melhorias significativas da funcionalidade motora global neste grupo. Verificaram-se ainda, em termos eletromiográficos um melhor padrão de recrutamento muscular, bem como, no que se refere à análise dinamométrica, evoluções positivas, na componente vertical das forças de reacção do solo.Conclusão: O presente estudo parece sugerir que a inclusão da facilitação da marcha em tapete rolante no plano de intervenção pode contribuir para uma melhoria nos parâmetros biomecânicos da marcha e funcionalidade global de crianças com Paralisia Cerebral do tipo diplégico e hemiplégico, com idades compreendidas entre os 3 e os 8 anos.

Position Statement on Bioresorbable Vascular Scaffolds in Portugal

BACKGROUND: Bioresorbable vascular scaffolds (BVS) were recently approved for percutaneous coronary intervention in Europe. The aim of this position statement is to review the information and studies on available BVS, to stimulate discussion on their use and to propose guidelines for this treatment option in Portugal. METHODS AND RESULTS: A working group was set up to reach a consensus based on current evidence, discussion of clinical case models and individual experience. The evidence suggests that currently available BVS can produce physiological and clinical improvements in selected patients. There are encouraging data on their durability and long-term safety. Initial indications were grouped into three categories: (a) consensual and appropriate - young patients, diabetic patients, left anterior descending artery, long lesions, diffuse disease, and hybrid strategy; (b) less consensual but possible - small collateral branches, stabilized acute coronary syndromes; and (c) inappropriate - left main disease, tortuosity, severe calcification. CONCLUSION: BVS are a viable treatment option based on the encouraging evidence of their applicability and physiological and clinical results. They should be used in appropriate indications and will require technical adaptations. Outcome monitoring and evaluation is essential to avoid inappropriate use. It is recommended that medical societies produce clinical guidelines based on high-quality registries as soon as possible.

A família cuidadora perante a dependência do seu familiar idoso

RESUMO: O envelhecimento demográfico tem vindo a acentuar-se nas últimas décadas. É expectável um aumento mais acentuado no número de pessoas com mais de 80 anos, o que importará maiores custos médicos, mais suporte familiar e comunitário, maior probabilidade de cuidados de longa duração devido à prevalência de doenças crónicas. Conduzindo a uma maior procura de apoios formais e informais. A preocupação com aqueles que atingem idades avançadas tem vindo a suscitar inquietação face à urgência de necessidades de suporte, sentidas por familiares, amigos e vizinhos. A questão central que orientou este estudo diz respeito aos familiares cuidadores ou gestores de cuidados do seu familiar idoso dependente e ao idoso dependente. Procurei identificar quais as dificuldades sentidas e as estratégias desenvolvidas pela família cuidadora ou gestora dos cuidados prestados ao idoso dependente, descrever e caracterizar a dependência destes idosos. É um estudo transversal, exploratório, descritivo, de abordagem quantitativa e qualitativa. Apliquei um questionário a 25 familiares cuidadores ou gestores dos cuidados a idosos dependentes, internados nos serviços de medicina e cirurgia de um hospital privado, Hospital CUF Descobertas, possuindo previamente alguma dependência. Dos dados obtidos ressalta que as principais dificuldades sentidas pelos familiares cuidadores ou gestores dos cuidados são essencialmente na gestão do tempo e a saúde do cuidador. Estratégias mais desenvolvidas foram o recurso a empregada doméstica e a outros familiares. Posso Concluir que há uma tendência preferencial por parte da família, na complementaridade de apoios informais e formais para prestar os cuidados ao idoso dependente no seio da família.------------ ABSTRACT: Demographic aging has risen progressively over the past decades. The number of people over the age of 80 years old is expected to increase considerably and surely result in the rise of medical costs, the growing need for additional community and family support, higher probability of long-term medical care due to the increased risk of chronic disease and the seeking of help regarding formal and informal support. The concern with persons that attain advanced age has brought about a certain degree of uneasiness regarding the urgency of the need of support systems felt by family members, friends, neighbours. The main topic that has steered this study pertains to the family caregivers or the care managers of dependant elderly relatives and dependant elderly persons. I endeavoured to identify encountered difficulties and the strategies undertaken by family caregivers or care managers in regard to the elderly dependant, to describe and characterize the nature of the dependency of these elderly persons. Furthermore, this study could be defined as being wide-reaching, exploratory and descriptive, by means of a qualitative and quantitative approach. I utilized a questionnaire that involved 25 family caregivers and care managers of dependant elderly (hospitalized in medical or surgery wards of private hospital, CUF Descobertas Hospital and suffering from some type of dependency). Conclusions: The main difficulties felt by family caregivers or care managers are primarily related to time management and the health of the caregiver. Let it be mentioned that more developed strategies were adopted such as the employment/recruitment of a housemaid and the help of other relatives. In sum, it can be concluded that there is a preferential tendency by families in seeking the complementarity of informal and formal support in order to provide the necessary care to the dependent elderly in the family environment.

O objetivo deste trabalho é determinar qual é o impacto do ecocardiograma transesofágico no diagnóstico de patologias da aorta susceptíveis de correção cirúrgica, na orientação da abordagem anestésica e cirúrgica e na monitorização destes pacientes no pós-operatório. Para o efeito, os seguintes itens foram estudados: impacto clínico geral do ecocardiograma transesofágico na cirurgia não cardíaca, ecocardiograma transesofágico no peri-operatório de aneurismas e disseções da aorta, da cirurgia endovascular da aorta, de lesões traumáticas da aorta, do tromboembolismo e de tumores da veia cava inferior.

Development of The Viking Speech Scale to Classify the Speech of Children with Cerebral Palsy

Surveillance registers monitor the prevalence of cerebral palsy and the severity of resulting impairments across time and place. The motor disorders of cerebral palsy can affect children’s speech production and limit their intelligibility. We describe the development of a scale to classify children’s speech performance for use in cerebral palsy surveillance registers, and its reliability across raters and across time. Speech and language therapists, other healthcare professionals and parents classified the speech of 139 children with cerebral palsy (85 boys, 54 girls; mean age 6.03 years, SD 1.09) from observation and previous knowledge of the children. Another group of health professionals rated children’s speech from information in their medical notes. With the exception of parents, raters reclassified children’s speech at least four weeks after their initial classification. Raters were asked to rate how easy the scale was to use and how well the scale described the child’s speech production using Likert scales. Inter-rater reliability was moderate to substantial (k > .58 for all comparisons). Test–retest reliability was substantial to almost perfect for all groups (k > .68). Over 74% of raters found the scale easy or very easy to use; 66% of parents and over 70% of health care professionals judged the scale to describe children’s speech well or very well. We conclude that the Viking Speech Scale is a reliable tool to describe the speech performance of children with cerebral palsy, which can be applied through direct observation of children or through case note review.

Toxoplasma-SPECIFIC IgG SUBCLASS ANTIBODY RESPONSE IN CEREBROSPINAL FLUID SAMPLES FROM PATIENTS WITH CEREBRAL TOXOPLASMOSIS

SUMMARY Cerebral toxoplasmosis can be highly debilitating and occasionally fatal in persons with immune system deficiencies. In this study, we evaluated the Toxoplasma gondii-specific IgG subclass antibody response in 19 cerebrospinal fluid (CSF) samples from patients with cerebral toxoplasmosis who had a positive IgG anti-T. gondii ELISA standardized with a cyst antigen preparation. There were no significant differences between the rates of positivity and the antibody concentrations (arithmetic means of the ELISA absorbances, MEA) for IgG1 and IgG2, but the rates of positivity and MEA values for these two IgG subclasses were significantly higher than those for IgG3 and IgG4. The marked IgG2 response in CSF from patients with cerebral toxoplasmosis merits further investigation.

Pré-Eclâmpsia de Causa Vascular: Será Possível a sua Profilaxia com Extracto de Ginkgo Biloba? Fundamentos Teóricos

O autor começa por descrever os aspectos normais do processo de placentação que se encontram alterados na pré-eclâmpsia. Os efeitos desse defeito reflectem-se no aumento da resistência vascular das artérias uterinas e que pode ser detectado ecograficamente (é assumido como possível método de rastreio às 23 semanas de gestação). São analisadas relações entre pré-eclâmpsia e síndroma de HELLP, síndroma dos anticorpos anti-fosfolípidos (SAAF) e atraso de crescimento intra-uterino (ACIU). Comentam-se as tentativas de prevenção de pré-eclâmpsia com ácido acetil salicílico (AAS) e com cálcio. São analisados os efeitos de vários agentes anti-hipertensivos na hemodinâmica uterina e fetal. É feita uma introdução da Ginkgo biloba, dos motivos que levam a escolhê-la como um bom candidato à terapêutica preventiva do desenvolvimento da pré-eclâmpsia, analisando os seus mecanismos de acção, a farmacodinâmica, as doses habitualmente utilizadas e a sua segurança. Por fim sugerem-se alguns critérios para investigar clinicamente os efeitos do extracto de Ginkgo biloba (EGB 761).

Successful Thrombolysis despite Having an Incidental Unruptured Cerebral Aneurysm

Purpose. To report a case of successful thrombolysis performed in a patient with an incidental unruptured intracranial aneurysm and review the literature. Case Report. Patient admitted for ischemic stroke due to left posterior cerebral artery occlusion, with an incidental right middle cerebral artery aneurysm, who underwent treatment with tissue plasminogen activator (rtPA) resulting in clinical improvement without complications. Conclusion. The presence of unruptured intracranial aneurysms is considered as a contraindication to thrombolysis, due to a potentially higher hemorrhagic risk of aneurysm rupture. Patients, otherwise, eligible for thrombolysis are usually excluded from receiving this emergent treatment, despite its potential benefits. A reevaluation of the strict exclusion criteria for thrombolysis in acute stroke patients should be considered.

Vascular Malformation and Common Keratinocytic Nevus of the Soft Type: Phacomatosis Pigmentovascularis Revisited

Phacomatosis pigmentovascularis is a rare syndrome characterized by the coexistence of a pigmented nevus and a cutaneous vascular malformation. We report a 5-year-old boy with all the typical findings of phacomatosis pigmentovascularis type Ia. Although its existence according to the traditional classification has been questioned, this case represents a very rare association of a capillary vascular malformation and a common keratinocytic nevus of the soft type.

Pulmonar Vascular Changes in the Plain Chest Film of Cardiac Patients

The correct interpretation of chest film on cardiac patients is very important. The most important feature is the radiographic appearance of the pulmonary vascularity. Four different patterns of pulmonary vascularity are considered: normal, decreased, increased and uneven. The different diseases associated with each type are mentioned. From the pulmonary vascular pattern one can deduct hemodynamic data which are important for the diagnosis, grade of severity and follow-up.

Coronary Revascularization Induces a Shift From Cardiac Toward Noncardiac Mortality Without Improving Survival in Vascular Surgery Patient

OBJECTIVE: Although evidence has shown that ischemic heart disease (IHD) in vascular surgery patients has a negative impact on the prognosis after surgery, it is unclear whether directed treatment of IHD may influence cause-specific and overall mortality. The objective of this study was to determine the prognostic implication of coronary revascularization (CR) on overall and cause-specific mortality in vascular surgery patients. METHODS: Patients undergoing surgery for abdominal aortic aneurysm, carotid artery stenosis, or peripheral artery disease in a university hospital in The Netherlands between January 2003 and December 2011 were retrospectively included. Survival estimates were obtained by Kaplan-Meier and Cox regression analysis. RESULTS: A total of 1104 patients were included. Adjusted survival analyses showed that IHD significantly increased the risk of overall mortality (hazard ratio [HR], 1.50; 95% confidence interval, 1.21-1.87) and cardiovascular death (HR, 1.93; 95% confidence interval, 1.35-2.76). Compared with those without CR, patients previously undergoing CR had similar overall mortality (HR, 1.38 vs 1.62; P = .274) and cardiovascular mortality (HR, 1.83 vs 2.02; P = .656). Nonrevascularized IHD patients were more likely to die of IHD (6.9% vs 35.7%), whereas revascularized IHD patients more frequently died of cardiovascular causes unrelated to IHD (39.1% vs 64.3%; P = .018). CONCLUSIONS: This study confirms the significance of IHD for postoperative survival of vascular surgery patients. CR was associated with lower IHD-related death rates. However, it failed to provide an overall survival benefit because of an increased rate of cardiovascular mortality unrelated to IHD. Intensification of secondary prevention regimens may be required to prevent this shift toward non-IHD-related death and thereby improve life expectancy.
