Diarreia de Causa Particular num Indivíduo Imunocompetente?

A colite a citomegalovírus em imunocompetentes é rara. Existe evidência que causa morbilidade e mortalidade nos imunocomprometidos. Os autores descrevem o caso de uma doente de 75 anos, admitida por diarreia com sangue, com 4 semanas de evolução com antecedentes de Diabetes Mellitus, Insuficiência cardíaca e renal crónica. Ao exame objectivo apresentava-se descorada, desidratada, hipotensa, com insuficiência cardíaca descompensada, abdómen indolor. Laboratorialmente verificou-se anemia, insuficiência renal crónica agudizada com acidose metabólica e aumento da proteína C reactiva. Após estabilização procedeu-se a investigação tendo realizado vários exames dos quais colonoscopia total que mostrou: mucosa de aspecto edemaciado e hiperemiado com úlceras de diferentes tamanhos, com distribuição segmentar, atingindo todo o cólon. O exame anatomo-patológico revelou: colite a citomegalovírus. A doente realizou terapêutica com ganciclovir com melhoria clínica, endoscópica e histológica.

Impacto da Idade no Tratamento e Resultados Após Enfarte Agudo do Miocárdio em Particular nos Muito Idosos

INTRODUCTION: The elderly population admitted for acute myocardial infarction is increasing. This group is not well studied in international trials and is probably treated with a more conservative approach. OBJECTIVES: To evaluate the presentation and treatment of myocardial infarction according to age, particularly in very elderly patients. METHODS: We studied 1242 consecutive patients admitted with acute myocardial infarction, assessing in-hospital, 30-day and one-year mortality during follow-up for each age-group. Patients were divided into four groups according to age: <45 years (7.6%); 45-64 years (43.3%); 65-74 years (23.4%); and ≥75 years (25.7%). RESULTS: Elderly patients had a worse risk profile (except for smoking), more previous history of coronary disease and a worse profile on admission, with the exception of lipid profile, which was more favorable. With regard to treatment of the elderly, although less optimized than in other age-groups, it was significantly better compared to other registries, including for percutaneous coronary angioplasty. Both complications and mortality were worse in the older groups. In elderly patients (≥75 years), adjusted risk of mortality was 4.9-6.3 times higher (p<0.001) than patients in the reference age-group (45-64 years). In these patients, the independent predictors of death were left ventricular function and renal function, use of beta-blockers being a predictor of survival. CONCLUSIONS: Elderly patients represent a substantial proportion of the population admitted with myocardial infarction, and receive less evidenced-based therapy. Age is an independent predictor of short- and medium-term mortality.

How Were Conflicts of Interest Handled?

Conflicts of interest were potentially great but they were minimized by the great conviction from both Doctors and Health Ministry that something had to be done to improve data on perinatal health. To decrease the number of hospitals where deliveries took place, to concentrate doctors, nurses and equipment, to define staff and to acquire equipment and to train nurses and paediatricians was the way. One the point of view of cost-effectiveness, centralization of expensive technologies, and development of expertise concentrating cases in a same centre - Surgery, VLBW, etc- and lowering mortality rates and get better outcomes were clear health gains. In 1989 after the political decision of closing small maternities the committee return to villages and cities to explain to political local power and people, the decision, which kind of care they will have in the future, why and expected gains. Level I hospitals and Health Centers stop to have deliveries; Health Centers were given a great responsibility: the follow up of the most part of the normal pregnancies by GP. There was no economic pressure because the National Health Service is free, there are no economic incentives for obstetrical or neonatal care, hospitals are financed through ICD, hospital level is defined according to both delivery and newborn care. In 1989 the rule was “No results can be obtained without the interested and responsible participation of all – institutions and people”. At that time the emphasis was on training. There are geographic influences on regionalization for example for islands and inner and far geographic areas. Also we would like to emphasize the influence of demographics on regionalization. As birth rate continues to decrease the hospitals left open 20 years ago with more than 1500 deliveries have to be closed now because the number of deliveries decreased. It was much more difficult and unacceptable to close some few maternities now than 20 years ago. All the difference was that at that time reasons were explained and now it was a Minister order. Other fearful events are the opening of private hospitals, the lowering gross national income, the economic difficulties and financial problems.
