Anuloplastia concêntrica do anel mitral, isolada ou associada à ressecção quadrangular, em crianças e jovens Mitral annuloplasty either in isolation or associated with posterior quadrantectomy in young patients

OBJETIVO: Descrever procedimento cirúrgico de anuloplastia concêntrica do anel mitral sem prótese, isolada ou associada à ressecção quadrangular com plicatura póstero-medial do anel mitral, e analisar os resultados imediatos e tardios obtidos. MÉTODO: Entre fevereiro de 1986 e fevereiro de 2001, realizamos 790 procedimentos abordando a valva mitral, 41 foram realizados em crianças e adolescentes menores de 20 anos (média de 9,7 anos). Vinte (48,7%) pacientes eram do sexo feminino e 21 (51,3%) do masculino. A doença reumática foi responsável pelas lesões em 92,6% dos casos e a degeneração mixomatosa em apenas 7,4%. No período pré-operatório, 22 (53,6%) pacientes estavam em classe funcional III e 19 (46,4%) em classe funcional IV, advindos de repetidos surtos de febre reumática, agravados pela desnutrição. A técnica cirúrgica utilizada foi a anuloplastia concêntrica, aplicada isoladamente ou em associação à ressecção quadrangular com plicatura póstero-medial. O curso do seguimento pós-operatório foi de 7 meses a 15 anos (3/2/1986 a 12/2/2001). RESULTADOS: A mortalidade hospitalar foi de 2,4%. Os pacientes receberam alta sem sopro sistólico de regurgitação mitral. Dois pacientes apresentaram, ao longo dos anos (4 e 11 anos), estenose mitral e necessitaram reoperação, um deles operado com dois anos de idade. Dois doentes foram reoperados para corrigir disfunção aórtica previamente abordada por plastia (12 e 18 meses após a primeira operação), morrendo e contribuindo para mortalidade tardia de 5%. CONCLUSÃO: Consideramos a técnica empregada um procedimento alternativo, válido, de aplicação preferencial em crianças e adolescentes, de fácil reprodução e de baixíssimo custo.OBJECTIVE: To describe the mitral anuloplasty technique either in isolation or associated with posterior quadrantectomy and to analyze the immediate and late results in young patients. METHOD: Between February 1986 and February 2001, 790 mitral valve procedures were performed in our Institution including 41 annuloplaties in patients with ages ranging from 1 to 20 years (Mean age = 9.7 years). 51.7% were males. The main etiologies were rheumatic disease (92.6%) and myxomatous degeneration (7.4%). Twenty-two (53.6%) patients were preoperatively in functional class III (NYHA), and 19 (46.4%) in class IV (NYHA), some in course of rheumatic fever aggravated by malnutrition. The technique employed was concentric mitral annuloplasty either in isolation or associated with posterior quadrantectomy. The follow-up ranged from 7 months to 15 years. RESULTS: The hospital mortality rate was 2.4%. All patients were discharged without mitral regurgitation. Two patients coursed with mitral stenosis (after 4 and 11 years respectively) and valve replacement was needed. Two patients coursed with aortic insufficiency (after 12 and 18 months) and died after aortic valve replacement, contributing to a 5% late mortality rate. CONCLUSION: In conclusion, mitral annuloplasty without ring either in isolation or associated with posterior quadrantectomy is a safe, easily reproducible especially in young patients

Contribuições da Sociologia na América Latina à imaginação sociológica: análise, crítica e compromisso social Sociology's contribution in Latin America to sociological imagination: analysis, critique, and social commitment

O artigo aborda o papel desempenhado pela Sociologia na análise dos processos de transformação das sociedades latino-americanas, no acompanhamento do processo de construção do Estado e da Nação, na problematização das questões sociais na América Latina. São analisados seis períodos na Sociologia na América Latina e no Caribe: I) a herança intelectual da Sociologia ; II) a sociologia da cátedra; III) O período da "Sociologia Científica" e a configuração da "Sociologia Crítica"; IV) a crise institucional, a consolidação da "Sociologia Crítica" e a diversificação da sociologia; V) a sociologia do autoritarismo, da democracia e da exclusão; VI) a consolidação institucional e a mundialização da sociologia da América Latina (desde o ano de 2000), podendo-se afirmar que os traços distintivos do saber sociológico no continente foram: o internacionalismo, o hibridismo, a abordagem crítica dos processos e conflitos das sociedades latino-americanas e o compromisso social do sociólogo.<br>The article focuses on the role played by Sociology in the analysis of processes of change in Latin American societies, in the process of construction of Nation and State, in the debate of social issues in Latin America and the Caribbean. Six periods in Sociology in Latin America and the Caribbean are examined: I) sociology's intellectual legacy; II) sociology as a cathedra; III) the period of "Scientific Sociology"; IV) the institutional crisis, the consolidation of "Critical Sociology", and the diversifying of sociology; V) sociology of authoritarianism, democracy and exclusion; VI) institutional consolidation and globalization of Latin American sociology (since 2000). It may be said that the distinctive features of sociological knowledge in the continent were: internationalism, hybridism, the critical approach to processes and conflicts of Latin American societies, and the sociologist social commitment

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.
