Anal-rectal cytology: A review
The incidence of invasive anal squamous cell carcinoma, a human papilloma virus (HPV) related cancer, is on the rise, especially in HIV positive men who have sex with men (MSM). Like cervical cancer, anal cancer is associated with precursor lesions detectable on exfoliative cytology as squamous intraepithelial lesions and on biopsy as intraepithelial neoplasia. Anal-rectal cytology screening programs, similar to cervical cytology screening programs, have been developed in an effort to detect and to eradicate precursor lesions prior to progression to invasive squamous cell carcinoma. Either conventional or liquid-based anal-rectal cytology specimens are acceptable, but liquid-based specimens are preferred. Specimens may be collected by health care professionals or by patients. A minimum of ......

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. Squamous intra-epithelial lesions were also observed in 38% of the patients without condyloma (18/47): in 9 of the 33 patients without history of condyloma (27%) and in 9 of the 14 patients who had previously treated condyloma (64%). An invasive squamous cell carcinoma was observed in one patient without history of condyloma. In all 13 patients with HSIL, biopsies guided by high resolution anoscopy confirmed high grade dysplasia. Our ......

Management of Anal Squamous Intraepithelial Lesions
Clinics in Colon and Rectal Surgery 2009; 22: 094-101DOI: 10.1055/s-0029-1223840ABSTRACTAnal squamous intraepithelial lesions include both low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) and are caused by chronic infection with the human papillomavirus (HPV). The disease is increasing in both incidence and prevalence, especially among patients with the following risk factors: homosexual men, acquired or iatrogenic immunosuppression, and presence of other HPV-related diseases. Although the natural history of the disease is unknown, there is significant evidence that untreated HSIL progresses to squamous cell carcinoma in 11% of patients and in up to 50% of patients with extensive disease and immunosuppression. Anal cytology and reflex......

[Anogenital warts: a clinical, pathological and virological study.]
The objective of this study was to investigate the possible relationship between the presence of anogenital warts (AGW) in children and the sexual abuse as mode of transmission. Our series includes 8 patients with AGW who were treated in our hospital during the year 2007. A complete physical examination was carried out, including colposcopy or anoscopy, and samples were taken for histopathological examination and human papiloma virus (HPV) subtyping. We considered perinatal transmission as a possible route in two cases. Although sexual abuse was definitively confirmed in only one case, we observed some findings in four cases that led us to consider the possibility of sexual abuse. We did not consider the possibility of heteroinoculation or autoinoculation from common warts in any case. Our......

Comparison of patient- and clinician-collected anal cytology samples to screen for human papillomavirus-associated anal intraepithelial neoplasia in men who have sex with men.
CONCLUSION: In a community-based sample, a high proportion of HIV-positive and HIV-negative men who have sex with men have AIN. The sensitivity of cytology to detect AIN is higher for clinician-collected versus self-collected specimens and for HIV-positive versus HIV-negative men. The specificity of cytology to detect AIN is higher in HIV-negative versus HIV-positive men. However, the probability of AIN in a patient with a negative cytology result may not be low enough (23% for HIV-negative men and 45% for HIV-positive men with a patient-collected specimen) for clinicians to be comfortable recommending no anoscopy for those with a negative cytology result if done as a one-time test. These data raise the question of whether the optimal population screening strategy is cytology screening wit......

Videoanoscope-assisted stapled haemorrhoidopexy: analysis of 18 patients
Abstract An optimal stapled haemorrhoidopexy requires the purse-string suture to be placed circumferentially at a constant distance
from the dentate line and to pass through an appropriate thickness of rectal mucosa. An unsuitable purse-string suture may
increase the risk of postoperative complications. We developed a new anoscope (the videoanoscope) to prevent the difficulties
during application of the purse-string suture, and we used the videoanoscope in 18 stapled haemorrhoidopexy procedures. The
videoanoscope is made up of three pieces. The front part is in the form of an open half-cylinder. The second piece is a sliding
lid that covers the front piece. The rear part of the anoscope includes a hollow handle in which a scope can be inserted,
and the whole procedure can ......

Management of internal genital warts: do we all agree? A postal survey
A postal survey was undertaken to determine whether there was any consensus of opinion regarding the management of internal genital warts in genitourinary medicine clinics in the UK. Overall, 110 forms were returned (57% response). The majority of clinics would refer patients with cervical warts for colposcopy especially if the patient was over the age of 25 or HIV-positive. Proctoscopy or anoscopy was performed in 60% of clinics for patients with perianal warts to determine the presence of warts within the anal canal or rectum. Only 24% of patients with intra-anal warts are referred directly to surgery for biopsy, increasing to 61% if the patient has HIV infection. Cryotherapy is the main treatment for all types of internal warts. Our findings suggest there is no consensus and we recommen......

Hybrid Capture II Detection of Oncogenic Human Papillomavirus: A Useful Tool When Evaluating Men Who Have Sex with Men with Atypical Squamous Cells of Undetermined Significance on Anal Cytology
Conclusions Hybrid-Capture II testing for high-risk human papillomavirus in men who have sex with men with atypical cells of undetermined
significance and referring only those with high-risk human papillomavirus reduces the number who require high-resolution anoscopy
by more than half. Five percent with high-grade squamous intraepithelial lesions would be missed.

High-Resolution Anoscopy in the Diagnosis of Anal Cancer Precursor Lesions in Renal Graft Recipients
Conclusions With a prevalence of 23.81% of subclinical ASIL-ACU lesions, the studied renal graft recipients had all these lesions detected
by high-resolution anoscopy, notwithstanding most anal transition zone acetowhitened biopsied areas did not reveal histopathological
aspects of anal cancer precursor lesions or condyloma acuminatum. Therefore, greater experience with the diagnostic tool was
felt necessary to enhance its positive predictive value, specificity and diagnostic precision.

Anal Human Papillomavirus Testing with Digene’s Hybrid Capture 2 Using Two Different Sampling Methods
Conclusions Anal screening for human papillomavirus-DNA by hybrid capture 2 is a useful method for detection of human papillomavirus-associated
disease. Sample collection using Dacron swabs identifies more human papillomavirus-positive patients, and yields higher relative
light unit values than using the cervical brush. Further studies are needed to determine the exact value of hybrid capture
2 in the screening for (pre)cancerous lesions of the anal canal.

High Resolution Anoscopy in the Planned Staged Treatment of Anal Squamous Intraepithelial Lesions in HIV-Negative Patients
Abstract Anal dysplasia (low-grade squamous intraepithelial lesions, LSIL; high-grade squamous intraepithelial lesions, HSIL) is a
challenging disease for the surgeon. We reviewed 42 patients that underwent high-resolution anoscopy (HRA)-targeted surgical
therapy of anal dysplasia in the past 10 years. Patients were followed up in the Anal Neoplasia Clinic with physical examination,
cytology, HRA, and biopsy if indicated. Patients with disease amenable to local therapy were treated with office-based HRA-directed
therapies. There were 30 men (mean age 39 years, range 21–63) and 12 women (mean age 50 years, range 31–71) included in the
study. HSIL was present in 33, with four undergoing planned staged treatment due to circumferential disease. HSIL recurred
