ABSTRACT

No presente trabalho, estudamos a frequência de achados de esfregaços anormais pelo exame de Papanicolaou nas populações de adolescentes (idade <=21 anos)e adulta (>21 anos) atendidas pelo Setor de Citologia do Instituto Adolfo Lutz-Programa de Prevenção do Câncer de Colo Uterino nos últimos seis anos (1996 a 2001). Verificamos que a frequência destes achados vem aumentando gradativamente em ambas as populações, sendo sempre mais alta nas adolescentes (1,7 por cento, 2,3 por cento, 1,8 por cento, 1,3 por cento, 2,6 por cento e 4,2 por cento respectivamente). Nas mulheres adultas, as lesões também sobreram progressivo aumento com o passar dos anos, com ocorrência de 1,2 por cento, 1,3 por cento, 1,0 por cento, 0,9 por cento, 1,6 por cento e 2,5 por cento respectivamente. A análise estatística mostrou uma tendência linear de aumento de frequência de exames anormais em ambos os grupos sendo maior nas adolescentes. Acrescendo os dados dos quatro anos precedentes (1992 a 1995) de estudo similar, publicado anteriormente, envolvendo o mesmo tipo de populações, as diferenças foram ainda mais notáveis com relação aos anos posteriores: de 1992 a 1995, a frequência de lesões na população de adolescentes foi de 0,45 por cento, 0,95 por cento, 1,12 por cento e 2,10 por cento, e na população de adultas, 0,44 por cento, 0,72 por cento, 0,87 por cento e 1,18 por cento respectivamente. Uma vez que a progressão das lesões para câncer cervical se dá em um período médio de dez anos, é de grande importância que a população mais jovem, sexualmente ativa, também seja monitorada pelos Programas de Prevenção de Câncer do Colo Uterino.

The aim of the present study was to ascertain the frequency of abnormal PAP smears(ASCUS, AGUS, SILs and carcinoma) in two populations that search for the Program of Cervical CancerPrevention of the Public Health Services of São Paulo State (Brazil) in the last six years (1996 to 2001):adolescents (up to the age of 21 years) and adults (over 21 years). The samples were examined at Divisionof Pathology of Adolfo Lutz Institute. The frequency of uterine cervix lesions is increasing constantly inboth populations but mainly in adolescents (1.7%, 2.3%, 1.8%, 1.3% 2.6% and 4.2% respectively). Theadult women also have showed a progressive increasing of the lesions during the period studied: 1.2%,1.3%, 1.0%, 0.9%,1.6% and 2.5%, respectively. The addition of data of four anterior years (1992 a1995) of a similar study previously published, involving the same type of populations, the differences werestill further notable if compared to the posterior years: from 1992 a 1995, the frequency of lesions in theadolescent population was 0,45%, 0,95%, 1,12% e 2,10%, and in the adult population was 0,44%, 0,72%,0,87% e 1,18%, respectively.Statistical analysis showed a tendency of linear increase in frequency of abnormal PAP smears in bothgroups, being greater in the adolescent group. Since the progression of intraepithelial lesions to invasivecancer may occur in a period of ten years, the younger sexually active population should be monitored byregular programs for uterine cervix cancer detection.

ABSTRACT

CONTEXT: AIDS is one of the most important risk factors for progression and recurrence of anogenital condyloma. In a previous work, we observed that patients with warts and high-grade AIN (HAIN) had recurrences more frequently than did patients with warts without AIN. The mechanisms of this increased incidence of high-grade lesions in AIDS are not known. OBJECTIVE: We studied the expression of the proliferative marker Ki-67 by immunohistochemical methods, in specimens of anal condyloma from HIV+ patients to clarify whether its expression can be associated to the grade of AIN. DESIGN: A retrospective study of hiltological specimens. SETTING: University referral unit. SAMPLE: 34 patients were divided into two groups: (1) condylomas with low grade AIN (LAIN), with 25 patients; and (2) condylomas with HAIN, with 9 patients. In this latter group we examined two areas: 2A (HAIN area) and 2B (LAIN area). MAIN MEASUREMENTS: The immunohistochemical reaction for Ki-67 was done on histological sections. Slices were lightly stained with hematoxylin, to help us in Ki-67 positive cell counting. The percentage of Ki-67 marked nuclei was calculated. We applied one-way variance analysis for statistics. RESULTS: The mean number of Ki-67 positive cells in group 1 was 19.68 + or - 10.99; in group 2 (area A) it was 46.73 + or - 10.409; and in area B it was 36.43 + or - 14.731. There were statistical differences between groups 1 and 2A and between groups 1 and 2B. Ki-67 positive cells predominated in the lower layer in LAIN. Positive Ki-67 cells were found in all layers in group 2A, and in group 2B they predominated in the two lower or in all layers of the epithelium. CONCLUSIONS: Our results suggest that LAIN areas (using routine staining techniques) in HAIN can have a biological behavior more similar to HAIN

ABSTRACT

Cento e sessenta e três mulheres atendidas pelo Departamento de Ginecologia do Hospital A. C. Camargo, em 1990, foram avaliadas quanto à incidência de Candida sp. pelos métodos de Papanicolaou e cultura, de forma prospectiva e aleatória. Todas as pacientes foram examinadas pelos dois métodos em estudo cego. A presença de fungos candida sp. foi observada em 27 (8,28 por cento) amostras pelo método de Papanicolaou e em 36 (11 por cento) amostras pela cultura. Näo houve diferença significativa da incidência de Candida sp. com relaçäo ao método da colheita usado
