Comparison between anal cytology, high-resolution anoscopy and HPV DNA genotyping by polymerase chain reaction in the post-treatment follow-up of condylomata acuminata.

Aim: to evaluate the presence of subclinical HPV-induced anal lesions with anal cytology, High-Resolution Anoscopy (HRA) and HPV genotyping by polymerase chain reaction (PCR) in the follow-up of treated condylomata acuminata (CA).

Methods: seventy-nine male patients were included. One month after anal CA eradication, the patients underwent brush samples collection for anal cytology and PCR, and HRA with biopsy of acetowhite lesions.

Local control of human papillomavirus infection after anal condylomata acuminata eradication.

Objective: To verify whether the eradication of anal condylomata acuminata was effective for local control of HPV infection using anal colposcopy and anal brush cytology.

Methods: We evaluated 147 patients treated for anal margin and/or anal canal condyloma, with 108 HIV-positive and 39 HIV-negative individuals. The average age for males was 40 years for HIV-positive and 27.

[How far into the anal canal should the brush be introduced for more efficient cytological evaluation?].

Objective: In literature, sensitivity of Pap smears ranges widely from 45 to 98%. Possibly this is because there is no standard for how far the brush should be introduced into the anal canal. The aim was to evaluate whether the sampling site has an influence on the results of anal Pap smears.

Anal cytology in patients with AIDS.

The objective of the present study was to study the prevalence of abnormal anal cytology in patients with AIDS. Anal smears, obtained with a cytobrush, of 102 HIV-positive patients of the Emilio Ribas Institute (Sao Paulo, Brazil) were collected, and only after that, the patients were submitted to anoscopy. Thirty-two patients had LSIL and 14 others had HSIL.
