Abstract: OBJECTIVE: Detect of cardiac alterations in children with AIDS and compare their evolution with the administration of only one anti-retroviral and the recent cases who received drugs in combination. METHODS: We prospectively studied 47 children in 3 groups: group 1, 20 cases treated only with zidovudine; group 2, 10 patients treated initially with zidovudine and later with a combination of drugs and in group 3, 17 patients, who receiced two or three since the beginning. In all patients it was done chest X-ray, EKG and echocardiography every 6 months and after death complete pathological study. RESULTS: Among the 45 patients cases 26 (57%) were index cases. Malnutrition, diarrhea tachycardia, signs of congestive heart failure, pericardial effusion, abnormal ventricular repolarization and arrhythmias were more frequent in group 1. Echocardiographic abnormalities were present in 10 (50%) children of group 1. They were less frequent in the others two groups. In regard to the outcome in group 1, two patients had worsening of sings of cardiomyopaty and 4 died. Cardiac dysfunction in all cases of group 2 and 3 improved with the medication. CONCLUSION:- The children who received combination and their cardiac alterations had more favorable outcome than those who received only one drug.

Abstract: OBJETIVO: Avaliar a gravidade das complica es cardíacas na asfixia neonatal, sua evolu o e correlacioná-las com o grau e dura o do processo hipóxico. MéTODOS: Foram estudados 90 bebês nos últimos 7 anos com grau de Apgar <6 no 5°min de vida. Pelo protocolo, após o exame físico e os cuidados intensivos, eram submetidos a dosagem do pH arterial, CPK-MB, DHL, glicemia, além da realiza o de radiografia de tórax, eletrocardiograma (ECG), ecocardiograma, seriados e repetidos a cada semana. Aqueles que faleceram eram levados à necropsia. RESULTADOS: Dos 90, 73 (81%) eram prematuros, 30 (41%) eram apropriados para a idade gestacional (AIG) e 43 (59%) eram pequenos(PIG). Em 21 (23%) casos havia pH arterial <7,2. Os quadros clínicos mais observados foram: pneumonia em 28 (31%), anemia 24 (26%) e icterícia moderada 12 (5%), entre outros. Ao exame físico observaram-se: sopro sistólico em 46 (50%), ictus propulsivo 18 (20%) e ICC em 8 (9%). No ECG, os sinais mais freqüentes foram altera es de repolariza o (ST e T) em 44 (49%). No ecocardiograma, observou-se persistência do canal arterial (PCA) em 20 (22%), regurgita o tricúspide em 6 (7%), hipertens o pulmonar em 6 (8%), hipocontratilidade de VE e dilata o de VD em 4 (5%). Dos 23 óbitos, 14 foram estudados e as altera es mais freqüentes foram necrose de fibras em 8 (68%) casos e em 4 (29%) congest o, vacuoliza o e perda de estria o. CONCLUS O: A maioria teve evolu o favorável mesmo naqueles que tiveram acidemia importante. Muitas altera es de ECG e ecocardiograma se normalizaram. Daqueles que evoluíram para o óbito, as les es mais graves ocorreram nos que sofreram, por mais tempo, processo anóxico.

Reflections on national identity and the state in Latin America Reflexiones sobre la identidad nacional y el Estado en América Latina

Abstract: This article describes and interprets the violent shock to which the native communities of America were subjected. How their forms of social organization were destroyed and how they were replaced by States which took charge of redistributing the natural resources of the continent. In this context, it tries to find the identity of a continent that denies its indigenous past and the knowledge that allowed those communities to coexist in permanent equilibrium with the environment. En este artículo se describe e interpreta el choque violento a que fueron sometidas las comunidades nativas de América. Cómo se destruyeron sus formas de organización social y cómo se remplazaron por Estados que se encargaron de redistribuir los recursos naturales del continente. En este contexto, se pretende encontrar la identidad de un continente que reniega de su pasado indígena y de los conociemientos que permitieron que esas comunidades convivieran en un equilibrio permanente con el medio ambiente.

Abstract: purpose: to evaluate the severity of cardiac complications of neonatal asphyxia in relation to the length and degree of hipoxia. methods: ninety babies with an apgar score <6 were examined in the intensive care unit at our institution during seven years. arterial blood for measuring ph, glucose, ldh and mb fraction of ck, together with serial electrocardiogram (ecg), echocardiogram and chest x rays was obtained. the fatal cases were studied with macro and microscopic examination. results: from a total of 90 cases, 73 were premature: 30 (41%) appropriate for gestation age (aga) and 43 (59%) small for gestation age (sga). twenty one (23%) cases had arterial ph <7.2. the most common clinical conditions were: pneumonia 28 (31%), anemia 24 (26%) and jaundice 12 (13%). the main cardiological findings were: systolic murmur in 46 (50%), signs of heart hypertrophy in 18 (20%) and heart failure in 8 (9%). on ecg the main findings were st and t abnormalities. the echocardiogram showed a patent ductus arteriosus (pda) in 20 (22%), tricuspid regurgitation in 6 (7%), pulmonary hypertension in 6 (7%), dyskinesia and ventricular dilatation in 4 (5%). necropsy was performed in 23 cases and macro and microscopy obtained in 14; the most frequent findings were: myocite necrosis in 8 (54%), congestion, vacuolization and loss of striae in 4 (29%). conclusion: in the majority of cases, patients had a benign course, even those presenting with severe acidemia. many abnormal ekgs and echocardiograms became normal after a few weeks. among those who had a fatal outcome, the severity of histological lesions was observed in babies who had suffered asphyxia for more prolonged periods.

Abstract: the coronary artery bypass surgery is frequently used to treat the residual lesion after myocardial infarction reperfusion. patients may undergo surgery during the acute or late phase. this study analyses the results of 45/159 (28%) patients who underwent a coronary bypass surgery after successful myocardial reperfusion with streptokinase or percutaneous transluminal coronary angioplasty (ptca). patients were divided into two groups accordingly to the reperfusion technique: i) 27 (60%) reperfused with the use of streptokinase, intracoronary in 22 (81%) and intravenous in 5 (18%); ii) 18 (40%) reperfused with the aid of ptca, alone in 10 (55%) and following previous streptokinase in 8 (45%). patientes were analysed at the moment of surgery, clinical evolution, late cinecoronariography and death, and were followed from 2 to 55 months. authors analise the results and the capacity of bypass surgery complement successfull myocardial reperfusion during acute myocardial infarction.

Abstract: the patent ductus arterious frequently occurs in premature neonates causing serious cardiopulmonary disfunction. the treatment includes two options; one clinic and the other surgical procedure. the surgery for patent ductus arteriosus has been done since 1938. clinical treatment with indometacin induces closure of the arteriosus ductus. the aim of the article is to analize the surgical results with thoractomy by triple-ligature of the ductus for the treatment of persistent ductus arteriosus in fourteen patients including low weight children and premature neonates with cardiopulmonary disfunction. the indications for surgery in these cases were respiratory distress and congestive heart failure. the technique used was triple-ligature of the patent ductus arteriosus. there were no complications neither mortality. the neonate intensive care unit was important for the evolution of these patients. our study showed good results achieved by this technique, with low mortality and morbidity and the importance of the intensive care unit for the evolution of these patients.
