Amaurose fugaz como sintoma inicial de carcinoma de células renais metastático

Introdução: Neste caso, descrevemos a apresentação rara da metástase orbitária de um carcinoma renal de células claras. Apresentação do caso: Apresentamos um caso de um homem de 57 anos de idade, que subitamente perdeu a visão em seu olho esquerdo associada à paralisia da abdução do mesmo. A ressonância magnética do crânio revelou um tumor intra-orbitário esquerdo com dimensões de 21,8 x 19,6 mm, provocando um deslocamento centro-lateral com consequente compressão do nervo óptico e do músculo reto lateral homolateral. O paciente foi submetido à remoção cirúrgica da lesão. O diagnóstico histológico indicou metástase de carcinoma renal de células claras confirmada pela tomografia computadorizada abdominal (TC), que apresentou neoplasia no terço superior do rim esquerdo, medindo 3,5 x 3,4 cm com reforço heterogêneo após administração intravenosa de contraste. Conclusão: Este caso descreveu a apresentação rara de uma metástase orbital de carcinoma renal de células claras. A apresentação inicial do paciente foi amarose fugaz e paralisia homolateral do nervo abducente. A metástase orbital de carcinoma renal de células claras é rara, no entanto, o exame histológico conclui o diagnóstico.Background: In this case we describe the rare presentation of orbital metastasis of a clear cell renal carcinoma. Case Report: We present a case of a 57-year-old male with suddenly lost the vision in his left eye and homolateral abducens palsy. The magnetic resonance imaging of the skull revealed a left intraorbital tumor with center-lateral displacement measuring 21.8 x 19.6 mm, compressing the optic nerve and the homolateral lateral rectus muscle. The patient underwent surgical removal of the lesion. The histologic diagnosis indicated clear cell renal carcinoma metastasis confirmed by the abdominal computed tomography (CT), which showed a neoplasia in the upper third of the left kidney measuring 3.5 x 3.4 cm with heterogeneous reinforcement after intravenous contrast administration. Conclusion: This case described the rare presentation of a clear cell renal carcinoma metastasis in orbit. The initial presentation of patient was amarosis fugax and homolateral abducens palsy. Orbital metastasis of clear cell renal carcinoma are rare, however, the histologic exam conclude the diagnosis

Perfil dos pacientes com transplante hepático devido à insuficiência hepática aguda atendidos no Hospital Universitário Walter Cantídio

Objetivo: Avaliar o perfil dos pacientes submetidos a transplante hepático em decorrência de insuficiência hepática aguda (IHA) atendidos no Hospital Universitário Walter Cantídio/UFC. Metodologia: Trata-se de estudo retrospectivo, longitudinal, observacional, no qual foram selecionados os pacientes submetidos a transplante hepático no período de janeiro de 2003 a julho de 2015, em decorrência de insuficiência hepática aguda. O coeficiente ρ (Rô) de Spearman foi elencado para cálculo estatístico das correlações estudadas neste trabalho. Resultados: O sexo feminino correspondeu a 90,5%, dos casos. A média de idade desses pacientes foi de 30,2 anos. Quanto à distribuição regional dos doentes acompanhados 66,6% dos indivíduos eram procedentes do Ceará, enquanto 33,4% residiam em outros estados. Na correlação entre a idade pré-transplante de 14 dos pacientes e a sobrevida por 1000 dias, obteve-se um coeficiente de correção de Spearman igual -0,004, não nos sugerindo que houve pior prognóstico para os pacientes mais velhos, quando estes desenvolveram IHA. Conclusão: A insuficiência hepática aguda, no espaço amostral do HUWC/UFC, é uma doença de adultos jovens, que acomete mais mulheres do que homens; em sua maioria pardos e negros, residentes predominantemente no interior do estado do Ceará

Magnesium supplementation alleviates drought damage during vegetative stage of soybean plants.

Our working hypothesis was that magnesium (Mg) supplementation modulates plant performance under low water availability and improves drought tolerance in soybean genotypes. Plants of Bônus 8579, M8808 and TMG1180 genotypes were grown under field conditions and subjected to three water stress treatments (control, moderate and severe stress) and three Mg levels [0.9 (low), 1.3 (adequate) and 1.7 cmolc dm-³ (supplementation)]. After 28 days of drought imposition, the growth parameters, osmotic potential, relative water content, leaf succulence, Mg content and photosynthetic pigments were assessed. In general, drought drastically decreased the growth in all genotypes, and the reductions were intensified from moderate to severe stress. Under adequate Mg supply, TMG1180 was the most drought-tolerant genotype among the soybean plants, but Mg supplementation did not improve its tolerance. Conversely, although the M8808 genotype displayed inexpressive responses to drought under adequate Mg, the Mg-supplemented plants were found to have surprisingly better growth performance under stress compared to Bônus 8579 and TMG1180, irrespective of drought regime. The improved growth of high Mg-treated M8808-stressed plants correlated with low osmotic potential and increased relative water content, as well as shoot Mg accumulation, resulting in increased photosynthetic pigments and culminating in the highest drought tolerance. The results clearly indicate that Mg supplementation is a potential tool for alleviating water stress in M8808 soybean plants. Our findings suggest that the enhanced Mg-induced plant acclimation resulted from increased water content in plant tissues and strategic regulation of Mg content and photosynthetic pigments

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
