    Renal tumor and trauma: a pitfall for conversative management

    Get PDF
    PURPOSE: Conservative management has been largely used for renal trauma. Although this approach is safe and highly recommended, it can hide a pre-existing unknown condition, such as tumors or urinary malformations. A high index of suspicion is needed for early recognition of these conditions. We present four cases treated at the Pediatric Oncology Institute - Federal University of São Paulo, which have been initially treated conservatively for renal trauma. MATERIALS AND METHODS: We reviewed all 218 renal cases of renal tumors treated at our institution in a 22-year period, searching for associated trauma events. RESULTS: Four cases of renal tumors were initially treated conservatively for blunt renal trauma of low energy mechanism. Patients' ages ranged from 7 to 12 years old. Two patients had no previous symptoms, one patient had hematuria and another had an abdominal mass. Computerized Axial Tomography (CT) of the abdomen revealed disparate magnitude of the renal bleeding to the low energy mechanism of trauma. All patients underwent surgical treatment. Kidney specimens showed Wilms tumor in three cases and renal carcinoma in one. CONCLUSIONS: The association between renal tumors and trauma should be suspected when renal trauma hemorrhage on abdominal CT scan does not match the low energy mechanism of blunt abdominal trauma. The key for a successful diagnosis of renal tumor or congenital malformations is the high index of suspicion for these conditions.Federal University of São Paulo Surgery DepartmentUNIFESP, Surgery DepartmentSciEL

    To determine the association between language and number of citations of ophthalmology articles published in Brazilian journals. This study was a systematic review. Original articles were identified by review of documents published at the two Brazilian ophthalmology journals indexed at Science Citation Index Expanded - SCIE [Arquivos Brasileiros de Oftalmologia (ABO) and Revista Brasileira de Oftalmologia (RBO)]. All document types (articles and reviews) listed at SCIE in English (English Group) or in Portuguese (Portuguese Group) from January 1, 2008 to December 31, 2009 were included, except: editorial materials; corrections; letters; and biographical items. The primary outcome was the number of citations through the end of second year after publication date. Subgroup analysis included likelihood of citation (cited at least once versus no citation), journal, and year of publication. The search at the web of science revealed 382 articles [107 (28%) in the English Group and 275 (72%) in the Portuguese Group]. Of those, 297 (77.7%) were published at the ABO and 85 (23.3%) at the RBO. The citation counts were statistically significantly higher (P<0.001) in the English Group (1.51 - SD 1.98 - range 0 to 11) compared with the Portuguese Group (0.57 - SD 1.06 - range 0 to 7). The likelihood citation was statistically significant higher (P<0.001) in the English Group (70/107 - 65.4%) compared with the Portuguese Group (89/275 - 32.7%). There were more articles published in English at the ABO (98/297 - 32.9%) than at the RBO (9/85 - 10.6%) [P<0.001]. There were no significant difference (P=0.967) at the proportion of articles published in English at the years 2008 (48/172 - 27.9%) and 2009 (59/210 - 28.1%). The number of citations of articles published in Portuguese at Brazilian ophthalmology journals is lower than the published in English. The results of this study suggest that the editorial boards should strongly encourage the authors to adopt English as the main language in their future articles.7626-

    Fast-growing Eucalyptus spp. forest plantations and their resultant wood products are economically important and may provide a low-cost means to sequester carbon for greenhouse gas reduction. The development of advanced and optimized frameworks for estimating forest plantation attributes from lidar remote sensing data combined with statistical modeling approaches is a step towards forest inventory operationalization and might improve industry e ciency in monitoring and managing forest resources. In this study, we first developed and tested a framework for modeling individual tree attributes in fast-growing Eucalyptus forest plantation using airborne lidar data and linear mixed-e ect models (LME) and assessed the gain in accuracy compared to a conventional linear fixed-e ects model (LFE). Second, we evaluated the potential of using the tree-level estimates for determining tree attribute uniformity across di erent stand ages. In the field, tree measurements, such as tree geolocation, species, genotype, age, height (Ht), and diameter at breast height (dbh) were collected through conventional forest inventory practices, and tree-level aboveground carbon (AGC) was estimated using allometric equations. Individual trees were detected and delineated from lidar-derived canopy height models (CHM), and crown-level metrics (e.g., crown volume and crown projected area) were computed from the lidar 3-D point cloud. Field and lidar-derived crown metrics were combined for ht, dbh, and AGC modeling using an LME. We fitted a varying intercept and slope model, setting species, genotype, and stand (alone and nested) as random e ects. For comparison, we also modeled the same attributes using a conventional LFE model. The tree attribute estimates derived from the best LME model were used for assessing forest uniformity at the tree level using the Lorenz curves and Gini coe cient (GC).We successfully detected 96.6% of the trees from the lidar-derived CHM. The best LME model for estimating the tree attributes was composed of the stand as a random e ect variable, and canopy height, crown volume, and crown projected area as fixed e ects. The %RMSE values for tree-level height, dbh, and AGC were 8.9%, 12.1%, and 23.7% for the LFE model and improved to 7.3%, 7.1%, and 13.6%, respectively, for the LME model. Tree attributes uniformity was assessed with the Lorenz curves and tree-level estimations, especially for the older stands. All stands showed a high level of tree uniformity with GC values approximately 0.2. This study demonstrates that accurate detection of individual trees and their associated crown metrics can be used to estimate Ht, dbh, and AGC stocks as well as forest uniformity in fast-growing Eucalyptus plantations forests using lidar data as inputs to LME models. This further underscores the high potential of our proposed approach to monitor standing stock and growth in Eucalyptus—and similar forest plantations for carbon dynamics and forest product planninginfo:eu-repo/semantics/publishedVersio

    Trata-se de um estudo do tipo descritivo, retrospectivo e documental, a partir da informação do Sistema de Informação em Saúde do Ministério da Saúde Vigilância Epidemiológica - ESUS VE, e, também, por meio de uma revisão bibliográfica dos estudos desenvolvidos por diversos pesquisadores, sobre a pandema de Covid-19. A doença teve o surto declarado como Emergência de Saúde Pública de Importância Internacional (ESPII), pela Organização Mundial da Saúde (OMS), em janeiro de 2020, e, como Pandemia, em março de 2020. A pandemia levou os diferentes países afetados a diversos esforços para conter a transmissão da doença, incluindo-se: quarentenas, medidas de higiene, restrições de viagem, adiamento ou cancelamento de eventos e fechamento de instalações e fronteiras. O objetivo principal deste estudo foi descrever o perfil epidemiológico dos casos de pacientes diagnosticados com COVID-19, no município de Contagem – MG, no ano de 2020. Os resultados apresentaram 566 óbitos no referido município, no período citado, os quais foram elencados por sexo, faixa etária e fatores de risco. Considerando o período analisado, onde  a pandemia do novo Coronavírus estava em plena expansão, medidas sanitárias foram reforçadas com mais rigidez, tais como: uso de máscara, álcool em gel e afastamento social. Novos trabalhos a respeito desse assunto devem ser realizados, principalmente, nos anos de 2021 e 2022, em função da vacinação da população, para que se tenha um parâmetro de comparação capaz de constatar se essas medidas foram ou não efetivas para controlar a contaminação e propagação do novo Coronoavírus
