RÉSUMÉ

Abstract Objective: To examine whether the DDAH2 promoter polymorphisms -1415G/A (rs2272592), -1151A/C (rs805304) and -449G/C (rs805305), and their haplotypes, are associated with PE compared with normotensive pregnant women, and whether they affect ADMA levels in these groups. Methods: A total of 208 pregnant women were included in the study and classified as early-onset (N=57) or late-onset PE (N =49), and as normotensive pregnant women (N = 102). Results: Pregnant with early-onset PE carrying the GC and GG genotypes for the DDAH2 -449G/C polymorphism had increased ADMA levels (P=0.01). No association of DDAH2 polymorphisms with PE in single-locus analysis was found. However, the G-C-G haplotype was associated with the risk for late-onset PE. Conclusion: It is suggested that DDAH2 polymorphisms could affect ADMA levels in PE, and that DDAH2 haplotypes may affect the risk for PE.

RÉSUMÉ

O objetivo deste estudo foi o de avaliar a eficácia da punção aspirativa por agulha fina (PAAF) da tireóide comparando-a com o diagnóstico histopatológico. Os autores avaliaram os resultados citológicos de 50 pacientes atendidos no período de dezembro de 1995 a julho de 1997, nos Departamentos de Citopatologia, Anatomia Patológica e Cirurgia da Santa Casa de Belo Horizonte, Minas Gerais. No mesmo período foram realizados 256 PAAF de tireóide, sendo que somente 50 pacientes foram à cirurgia e puderam ter os diagnósticos citológicos comparados aos histológicos. O grupo estudado consistiu em 40 mulheres e 10 homens, com idades variando entre 10 e 79 anos, sendo a maior incidência observada nas 4ª e 5ª décadas...
