ABSTRACT
Avaliou-se parâmetros reprodutivos e produtivos em vacas da raça Holandês-PB no pós-parto imediato, manejadas em free stall . Utilizou-se 51 vacas entre primíparas e pluríparas. Os valores obtidos foram: escore de condição corporal ao parto 3,47±0,4; intervalos do parto à primeira ovulação 5,89±3,4 semanas; ao primeiro serviço 112,5±57,0 dias; a taxa de gestação ao primeiro serviço foi 43,6% e no período experimental 76,4%, não sendo observada diferença para ordens de parto (P>0,05). A produção de leite acumulada à concepção, produção diária leite até a concepção e produção de leite ajustado para 305 foi respectivamente, 3.335,6±1.488,4; 25,8±5,4 e 7.424,0±1.877,8 litros. Conclui-se que no manejo de Free stall , a detecção de estro, foi o principal fator limitante para alcançar melhor eficiência reprodutiva.
The reproductive and productive parameters in postpartum of 51 primiparous and pluriparous Holstein cows housed in free stall were obtained. The values measured were: body condition score at parturition (3.47±0.4), interval from parturition to first ovulation (5.89±3.4 weeks), interval parturition at first service (112.5±57.0 days), first-service pregnancy rate (43.6%) and during the experimental period (76.4%). No difference was found between parturition order (P>0.05). The accumulated milk production until conception time, daily production until conception time, and adjusted 305-day milk production was respectively 3,335.6±1,488.4; 25.8±5.4 and 7,424.0±1,877.8 liters. In free stall of this study the estrus detection was the most limiting factor to improve the reproductive efficiency.

OBJECTIVE: Evaluation of inter and intraobserver reproducibility of by the visual method interpretation of cineangiogram in a clinically based context. METHODS: Five interventional cardiologists analyzed 11 segments of 8 coronary cineangiograms at a two month apart sessions. The percent luminal reduction by the lesions were analyzed by two different classifications: in one (A) the lesions were graded in 0% = absent, 1-50% = mild, 51 - 69 = moderate, and > or = 70% = severe; the other classification (B) was a dichotomic one : <70% = nonsignificant and > or = 70%=significant lesions. The agreement were measured by the kappa (k) index. RESULTS: Interobserver agreement was moderate for classification A (1st measurement, k = 0.36 - 0.63, k m = 0.49; 2nd measurement, k = 0.39-0.68, k m = 0.52) and good for classification B (1st measurement, k = 0.55-0.73, k m = 0.63; 2nd measurement, k = 0.37-0.82, k m = 0.61). Intraobserver levels of agreement were k = 0.57-0.95 for classification A and 0.62-1.0 for classification B. CONCLUSION: The higher level of reproducibility obtained by adopting the dichotomous criteria usually considered for ischemic limits demonstrates that in the present clinical context, the reliability of the simple visual method is adequate for the identification of patients with clinically significant lesions and candidates for myocardial revascularization procedures.

Evidences of a possible association between endomyocardial fibrosis and schistosomiasis have been recently investigated. We describe the finding of cardiac schistosomal granulomas in a 14 year-old-girl presenting symptoms and signals of right side endomyocardial fibrosis. Refractory ascistis and progressive atrioventricular block were observed during follow-up. Endomyocardial biopsy and post mortem specimens showed inflammatory infiltrates, schistosomal granuloma and fibrosis.

Alteraçöes do ritmo cardíaco podem ser encontradas normalmente em indivíduos saudáveis; o avanço da idade, entretanto, aumenta sua prevalência. Para identificar a frequência de arritmias em idosos sadios e naqueles portadores de doenças cardiovasculares, foram analisados os resultados dos exames de Eletrocardiografia Dinâmica de 24 horas realizados em 288 indivíduos, sendo 159 (55,2 por cento) do sexo feminino e 129 (44,8 por cento) do sexo masculino, com idade mínima de 60 anos (máxima de 97 e méd de 70 anos). Tais pacientes foram divididos em seis grupos, de acordo com os seus diagnósticos: 1) sem cardiopatia aparente, 2) com hipertensäo arterial sistêmica, 3) com doença arterial coronária, 4) com prolapso de valva mitral, 5) com miocardiopatias e 6) com valvulopatias. As arritmias supraventriculares estiveram presentes em 55,6 por cento dos pacientes estudados (extrassístoles em 38 por cento, taquicardia atrial em 8,7 por cento e ritmos ectópicos em 4,9 por cento) e as arritmias ventriculares crreram em 31 por cento (extrassístoles em 29,6 por cento e taquicardia näo sustentada em 1,4 por cento). Bradiarritmias foram registradas em 6,9 por cento dos casos. Dos 191 que apresentaram arritmias, 67,5 por cento näo relatavam quaisquer sintomas, enquanto que dos 32,5 por cento que os referiam, em apenas 3,2 por cento os mesmos estavam associados às arritmias. Os resultados do estudo confirmaram que as alteraçöes do ritmo cardíaco no idoso säo comuns e frequentemente assintomáticas, näo havendo difreça significativa em relaçäo à presença ou näo de doença cardiovascular.

Endomyocardial fibrosis (EMF) is a severe restrictive cardiomyopathy characterized by the formation of fibrous tissue on the endocardium and to a lesser extent in the myocardium of one or both ventricles. The disease results in endocardial rigidity, atrioventricular valve dysfunction and progressive obliteration of the ventricular cavity. The clinical and pathological findings of EMF have been well established and definitive diagnosis can be made by selective cineangiocardiography. However, there are few reports concerning the phonomechanocardiographic (PMCG) patterns in this condition. In this paper we describe the PMCG findings in 12 patients with EMF which is now recognized with increasing frequency in the Northeast of Brazil.

A 2-year-old boy who presented with unrelated recurrent respiratory infections was found to have an enlarged cardiac silhouette on his chest roentgenogram. Clinical evaluation, echocardiography and cardiac cineangiograms failed to provide an accurate diagnosis. A left ventricular tumor was identified by exploratory thoracotomy and successful excision of an intramural fibroma of the left ventricle subsequently accomplished.

Descreve-se o caso de uma paciente de 12 anos de idade, portadora de insuficiencia mitral reumatica, que desenvolveu endocardite bacteriana por Staphylococcus aureus. A infeccao determinou a formacao de um aneurisma sacular do ventriculo esquerdo, chegando a romper-se no saco pericardico. Realizou-se uma operacao de emergencia na qual se substituiu a valva mitral e se reparou o aneurisma,mas a paciente faleceu devido a fibrinolise. A raridade e os principais aspectos clinicos e cirurgicos desta condicao sao discutidos
