The diagnosis of Chagas' disease relies mostly on data provided by immunologic tests, but inconclusive results often require elucidation, especially in blood banks. When six different types of Trypanosoma cruzi epimastigote antigens were studied by an immunoblotting assay (IBA), a preserved protein antigen (Ag PP) was found to present the most interesting(More)
The frequencies of each type of arrythmia were investigated, by age and sex, among 3056 Brazilian patients with cardiac arrhythmia. Each patient investigated had been tested serologically for American trypanosomiasis and 1013 had been found seropositive for the disease. In general, the seropositive 'chagasic' patients were each likely to be suffering from(More)
A case of decompensated chagasic cardiopathy in a nine-year-old boy from the south of the State of Goiás, is described. He developed congestive heart failure four months before death. The serological reaction for Chagas' disease and the xenodiagnosis were positive. Electrocardiograms showed sinusal tachycardia, ventricular and supraventricular(More)
Synchronous multiple primary malignant neoplasms of different tissues or organs are being documented with increasing frequency. Awareness among clinicians is essential to the evaluation and follow-up of these patients. A rare case of the simultaneous occurrence of vulvar, breast and colon carcinoma underlines this fact.
A 13-year-old girl with chronic graft versus host disease (GVHD) developed severe proximal weakness. Muscle biopsy showed necrotic fibers with anti-IgG deposits and interstitial inflammation. Steroid treatment helped, but her weakness recurred. Repeat biopsy showed persistent inflammation and possible steroid myotoxicity. Numerical ratio of capillaries to(More)
PURPOSE To evaluate possible morphological changes in chronic chagasic of the right bundle trabecular branch (RB) with right branch block (RBB) and to draw clinicopathological correlations. METHODS Eight RBB chronic chagasic septo-marginal trabeculae (SMT) (group A), six left branch block (LBB) chagasic SMT (group B) and six SMT from non-chagasics with no(More)
Local anesthetics (LAs) are classified into 2 groups: ester and amide compounds. Adverse reactions are frequent, but most of them are attributed to vasovagal reflexes or hemodynamic changes after the injection of LAs with epinephrine. Allergic reactions to LAs are uncommon. The preponderance of evidence suggests that there is no cross-reactivity between(More)
