Tumores testiculares e paratesticulares na infância Testicular and paratesticular tumors in infancy and chilhood

Este estudo visa apresentar os dados referentes à idade, manifestação clínica, diagnóstico histopatológico e evolução de pacientes pediátricos portadores de neoplasia testicular e paratesticular tratados no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto. Procedeu-se a análise retrospectiva dos prontuários médicos de pacientes, com idade até 18 anos, portadores de neoplasia testicular primária e/ou paratesticular diagnosticados no período compreendido entre janeiro de 1984 a agosto de 2000. Foram atendidos 17 pacientes com idade entre 3 meses e 17 anos (mediana = 3 anos). O acometimento da gônada direita foi semelhante ao da esquerda (n=8 para cada lado), com 1 paciente apresentando tumor bilateral. A manifestação clínica mais frequente foi a de massa escrotal indolor. Nos tumores testiculares houve predomínio das neoplasia de células germinativas (n = 11), e 2 tumores de células de Leydig. Todos os tumores extratesticulares eram rabdomiossarcomas. Apesar da baixa incidência de neoplasia testicular e paratesticular na infância, esse diagnóstico deve ser considerado nos pacientes com massa escrotal indolor

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.
