Cirurgia Cardíaca em Doentes de Muito Alto Risco

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.

Bloqueio Aurículo-Ventricular de Alto Grau Induzido por Angina de Prinzmetal

Apresentamos o caso de uma mulher de 46 anos com episódios frequentes de dor precordial e síncope associados a elevação do segmento ST e períodos de bloqueio aurículoventricular de alto grau transitórios. A coronariogafia excluiu lesões significativas e a doente foi tratada com nitratos e antagonistas do cálcio. Verificou-se persistência da sintomatologia associada a períodos de bloqueio aurículo-ventricular sintomáticos, refratários a otimização terapêutica. Implantação de pacemaker DDD-R. Follow-up de 4 meses sem intercorrências.

First Diabetic Retinopathy Prevalence Study in Portugal: RETINODIAB Study-Evaluation of the Screening Programme for Lisbon and Tagus Valley Region

BACKGROUND/AIMS: In Portugal, so far, there is no study or even accurate data on the prevalence of diabetic retinopathy (DR), based on a large representative sample and on a long-term follow-up. The objective of our study was to determine the prevalence of DR based on a national screening community-based programme. METHODS: A 5-year retrospective analysis of the RETINODIAB screening programme results was implemented in Lisbon and Tagus Valley area between July 2009 and October 2014. We estimated the prevalence of retinopathy for all patients with type 2 diabetes and studied the association between known risk factors and retinopathy emergence at their first screening. RESULTS: Throughout this period, from a total of 103 102 DR readable screening examinations, 52 739 corresponded to patients who attended RETINODIAB screening at entry. Globally, DR was detected in 8584 patients (16.3%). Of these, 5484 patients (10.4%) had mild non-proliferative (NP) DR, 1457 patients (2.8%) had moderate NPDR and 672 (1.3%) had severe NPDR. Finally, 971 patients (1.8%) had proliferative DR requiring urgent referral to an ophthalmologist. The presence of any DR, non-referable DR or referable DR was strongly associated with increasing duration of diabetes and earlier age at diagnosis. CONCLUSIONS: The prevalence rate of DR in our study (16.3%) was slightly lower than other published international data. The RETINODIAB network proved to be an effective screening programme as it improved DR screening in Lisbon and Tagus Valley surrounding area
