5. Lesions in 224 spleens of splenectomized dogs and evalution of alternative techniques for previous microscopic diagnosis
RESUMO: Rotineiramente, frente à detecção de uma lesão proliferativa esplênica, médicos veterinários costumam optar pela esplenectomia antes de se obter o diagnóstico definitivo da lesão esplênica, o que pode trazer consequências deletérias ao cão. O mais apropriado seria, contudo, a sua adoção, como medida terapêutica, apenas nos casos com c

9. Performance of lactate in discriminating bacterial meningitis from enteroviral meningitis
ABSTRACT The cytological and biochemical examination of cerebrospinal fluid (CSF) has been used for the presumed diagnosis of bacterial meningitis until the final microbiological results are achieved. We assessed the ability of CSF lactate in comparison with other CSF parameters to discriminate bacterial and enteroviral community acquired meningitis. We incl

10. Reliability of Thyroid Imaging Reporting and Data System (TI-RADS), and ultrasonographic classification of the American Thyroid Association (ATA) in differentiating benign from malignant thyroid nodules
ABSTRACT Objective Ultrasonography (US) is the best diagnostic tool for initial assessment of thyroid nodule. Recently, data reporting systems for thyroid lesions, such as the Thyroid Imaging Reporting and Data System (TI-RADS) and American Thyroid Association (ATA), which stratifies the risk for malignancy, have demonstrated good performance in differentia

11. Is endobronchial ultrasound-guided transbronchial needle aspiration with a stylet necessary for lymph node screening in lung cancer patients?
During endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), a needle is commonly used with a stylet, although recently the stylet has been omitted. This prospective study aimed to compare the quality of specimens obtained by EBUS-TBNA performed with and without a stylet. Between November 2013 and November 2014, 131 patients with lung

12. Histopathological diagnosis of small melanocytic lesions suspicious for malignant melanoma
Abstract The concern about malignant skin neoplasms leads to the excision of smaller lesions. This study on small melanocytic lesions aims to evaluate the range of possible histopathological diagnoses, describe histopathological aspects, and assess the usefulness of serial histological sections. We performed a cross-sectional descriptive histopathological st
