1. The Current Role of Surgery in the Treatment of Cardiac Metastases from Malignant Melanoma: an Educational Presentation
Abstract A 71 year-old male with a history of multiple excisions of an initial Clark's level V melanoma of the breast followed by combined radiation and interferon treatment, as well as a recurrence, 3 years later, of a BRAF-positive tumor of the shoulder, with subsequent therapy with dabrafenib and trametinib, presented again with progressive intracardiac m

2. Echocardiografic abnormalities in patients with sickle cell/β-thalassemia do not depend on the β-thalassemia phenotype
ABSTRACT Objectives and methods: We evaluated possible relationships between echocardiographic findings and clinical and laboratory parameters, in a cohort of Brazilian patients diagnosed with sickle cell/β-thalassemia, to better understand the cardiac involvement in this disease. Results: Left atrial (LA) and left ventricular (LV) dilation were found in

3. Vanishing testes syndrome-related osteoporosis and high cardio-metabolic risk in an adult male with long term untreated hypergonadotropic hypogonadism
SUMMARY The male hypogonadism-related bone mass loss is often under diagnosed. Peak bone mass is severely affected if the hypogonadism occurs during puberty and is left untreated. We present an interesting; almost bizarre case of a male with non-functional testes early during childhood and undiagnosed and untreated hypogonadism until his fifth decade of life

4. Avaliação experimental do metabolismo energético em dois protocolos de sobrecarga sistólica do ventrículo direito / Experimental evaluation of energy metabolism in two right ventricle systolic overload protocols
Objective: Altered energy metabolism has been identified in myocardial hypertrophy. Some processes are considered beneficial, whereas others are linked to heart failure. The purpose of this study was to compare the activity of three different energy metabolism enzymes in two different protocols of right ventricle (RV) systolic overload in young goats. Method

5. Avaliação de massas cardíacas pela ecocardiografia com perfusão em tempo real / Evaluation of cardiac masses by real time perfusion imaging echocardiography
Introdução: As massas cardíacas (MC) podem ser tumores, trombos ou pseudotumores. A avaliação da vascularização poderá ser uma ferramenta adicional para o seu diagnóstico diferencial. Neste estudo, demonstrou-se o valor diagnóstico da ecocardiografia com perfusão na caracterização das MC or meio de análises qualitativas e quantitativas de perfu

6. A newly described scorpion species, Leiurus abdullahbayrami (Scorpion: Buthidae), and the lethal potency and in vivo effects of its venom
Currently, medically significant scorpion species belong to the Buthidae family and are represented by the genera Androctonus, Buthus, Mesobuthus, Hottentotta, Parabuthus, Tityus, Centruroides, Leiurus. Although Leiurus was originally considered a monotypic genus, four additional species have since been described. Leiurus abdullahbayrami (previously identifi

7. Esplenomegalias em cães: estudo retrospectivo e análise imunohistoquímica do Fator de Crescimento Endotelial Vascular (VEGF) / Splenomegaly in dogs: retrospective study and immunohistochemical analysis of Vascular Endothelial Growth Factor (VEGF)
New blood vessel formation is a fundamental event in the process of tumor growth and metastatic dissemination, being the vascular endothelial growth factor (VEGF) one of the key regulators of this process. The aim of this study was evaluate the VEGF immunohistochemical expression in splenic hemangiosarcomas and hemangiomas, and review the prevalence of canin

8. Assessment of intracardiac masses by transesophageal echocardiography.
Transesophageal echocardiography and 2-dimensional transthoracic echocardiography have proved to be extremely valuable in the diagnosis of cardiac masses. In this report, we review the echocardiographic findings, clinical history, and histopathologic findings in 21 patients with intracardiac masses who underwent transthoracic echocardiography, transesophagea

9. Unusual echocardiographic appearance of intracardiac thrombi in a patient with endomyocardial fibrosis.
A five year old girl presented with a four month history of recurrent heart failure, which subsequently proved to be caused by endomyocardial fibrosis. There was no evidence of valvar disease. Echocardiography showed several echogenic masses with echolucent centres within the cardiac cavity. Histological examination showed that these masses were partly organ

10. Evaluation by electron beam computed tomography of intracardiac masses suspected by transoesophageal echocardiography.
OBJECTIVES: To assess the suitability of electron beam computed tomography (EBT) in evaluating and subsequently managing cardiac masses suspected as a result of examination by transthoracic and transoesophageal cross sectional echocardiography. DESIGN AND PATIENTS: In 76 consecutive patients with suspected cardiac masses, the impact of the EBT examination wa

11. Cardiac echinococcosis--a rare echocardiographic diagnosis.
A 30 year old female admitted for evaluation of left chest pain was suspected to have multiple cardiac hydatid cysts. The diagnosis was established by cross sectional echocardiography and computed tomography, supported by enzyme linked immunosorbent assay (ELISA) for echinococcosis. Medical therapy altered the echopattern of the cysts but failed to reduce cy

12. Surgical Management of Metastatic Melanoma to the Ventricle
The treatment of patients who have cardiac tumors can be challenging, because these tumors occur infrequently and in variable locations, and surgical resection is often technically difficult. We report the cases of 2 patients, each of whom underwent successful surgical excision of large melanomas that had metastasized to the right cardiac ventricle. Although
