SUMMARY OBJECTIVE: The aim of this study was to evaluate the demographic data, molecular epidemiology, and in vitro antifungal susceptibility results of patients with Aspergillus isolated from various clinical specimens. METHODS: A total of 44 Aspergillus strains were studied. The definition of invasive aspergillosis in patients was made according to European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) criteria. Strains were phenotypically and molecularly identified. Demographic characteristics of patients and genotypes of strains were evaluated. Phylogenetic analysis was done by the The Unweighted Pair-Group Method with Arithmetic Mean (UPGMA). Antifungal susceptibility of strains was determined according to The Clinical and Laboratory Standards Institute (CLSI)-M61-Ed2 and The European Committee on Antimicrobial Susceptibility Testing (EUCAST). RESULTS: A total of 11 patients were classified as proven and 33 as probable invasive aspergillosis. There was a statistically significant difference in age groups, subdisease, neutropenic, and receiving chemotherapy between groups. A total of 23 strains were identified as Aspergillus fumigatus, 12 as Aspergillus niger, 6 as Aspergillus flavus, and 3 as Aspergillus terreus. Phylogenetic analysis revealed five different genotypes. No statistical difference was found in the comparisons between patients groups and genotype groups. There was a statistically significant difference between genotype groups and voriconazole, posaconazole, and itraconazole Minimum Inhibition Concentration (MIC). CONCLUSION: Accurate identification of strains and antifungal susceptibility studies should be performed due to azole and amphotericin B resistance. Genotyping studies are important in infection control due to identifying sources of infection and transmission routes.

RESUMO O Círculo de Willis é um importante sistema colateral que mantém a perfusão à área estenótica da carótida contralateral e da artéria basilar para a região de perfusão cerebral reduzida. O objetivo do presente estudo foi comparar a anomalia do Círculo de Willis em pacientes com doença carotídea assintomática e sintomática unilateral. Resultados Neste estudo retrospectivo, foram analisados 175 pacientes que foram à nossa clínica ambulatorial de AVC, entre janeiro de 2013 e junho de 2015, com doença carotídea assintomática ou sintomática unilateral, e que fizeram angiografia por tomografia computadorizada. Propriedades demográficas, estenose da artéria carótida e anomalia do Círculo de Willis foram registradas. Conclusão Não houve diferença estatisticamente significativa em pacientes com doença carotídea sintomática e assintomática em termos de anomalia do Círculo de Willis.

ABSTRACT The circle of Willis is an important collateral system that maintains perfusion to the stenotic area from the contralateral carotid and basilar artery to the region of reduced brain perfusion. The aim of the present study was to compare the circle of Willis anomaly in patients with unilateral symptomatic and asymptomatic carotid artery disease. Results In this retrospective study, we analyzed 175 patients who presented at our outpatient stroke clinic between January, 2013 and June, 2015 with either unilateral symptomatic or asymptomatic carotid artery disease, and who had had CT angiography imaging performed. Demographic properties, carotid artery stenosis and the anomaly of the circle of Willis was recorded. Conclusion There was no statistically significant difference in patients with symptomatic and asymptomatic carotid artery disease in terms of the anomaly of the circle of Willis.

OBJETIVO: Dado que a cintilografia Tl -201 24 horas de imagens por perfusão miocárdica foi introduzida como um procedimento adicional efetivo, assim, o objetivo deste estudo foi comparar os resultados deste método com o procedimento único de redistribuição no diagnóstico de viabilidade miocárdica. MÉTODOS: Trinta pacientes (Sete mulheres, 23 homens, média: 59,8 ± 10,7, 55,8-63,8 anos) com diagnóstico de doença arterial coronariana foram avaliados neste estudo. Todos os pacientes tinham anamnese de infarto do miocárdio e/ou oclusão total de uma artéria principal na cinecoronariografia. Cintilografia de perfusão miocárdica com protocolo de Tl-201 em repouso, redistribuição quatro horas (início) e redistribuição tardia 24 horas foi realizada em todos os pacientes. As imagens foram avaliadas de acordo com a base de 17 segmentos por um médico com experiência em medicina nuclear e melhoria de um segmento por interpretação visual foi considerado como tecido miocárdico viável. RESULTADOS: A viabilidade foi encontrada em 52 segmentos de redistribuição das imagens iniciais e 18 segmentos adicionais nas imagens de redistribuição tardias de 24 horas baseadas em segmento, na avaliação de 510 segmentos de 30 pacientes. Em termos de pacientes, entre os 26 pacientes que tinham tecido viável, 14 (54%) apresentaram melhora adicional em imagens tardias de 24 horas. Três (12%) pacientes tiveram tecido viável apenas em imagens tardias de 24 horas. CONCLUSÃO: A imagem tardia em TL- 201 MPS é uma aplicação necessária para a avaliação do tecido viável de acordo com o número considerável de pacientes com melhora adicional em imagens de 24 horas em nosso estudo, o qual é restrito aos pacientes com infarto do miocárdio.

OBJECTIVE: Since twenty-four-hour imaging by Tl-201 myocardial perfusion scintigraphy has been introduced as an effective additional procedure, the aim of this study was to compare this method's result with only rest redistribution procedure in the diagnosis of myocardial viability. METHODS: Thirty patients (Seven female, 23 male; mean: 59.8 ± 10.7, 55.8-63.8 years old) with diagnosis of coronary artery disease were involved in this study. All patients had anamnesis of previous myocardial infarction and/or total occlusion of any main artery in the coronary angiography. Myocardial perfusion scintigraphy with Tl-201 with rest four hour (early) redistribution and 24 hour delayed redistribution protocol were performed to all of the patients. The images were evaluated according to 17 segment basis by an experienced nuclear medicine physician and improvement of a segment by visual interpretation was considered as viable myocardial tissue. RESULTS: Viability was found at 52 segments in the early redistribution images and additional 18 segments in the 24 hour delayed redistribution images on segment basis in the evaluation of 510 segments of 30 patients. On per patient basis, among the 26 patients who had viable tissue, 14 (54%) had additional improvement in 24 hour delayed images. Three (12%) patients had viable tissue in only 24 hour delayed images. CONCLUSION: Delayed imaging in Tl-201 MPS is a necessary application for the evaluation of viable tissue according to considerable number of patients with additional improvement in 24 hour images in our study, which is restricted to the patients with myocardial infarct.
