New Screening Strategy Combining Anal Papanicolaou and Human Papillomavirus Tests for Human Papillomavirus-Related Anal Cancer: A Prospective, Single-Center Study.

BACKGROUND: The objective of this study was to evaluate the performance of a combined approach of liquid-based anal cytology and human papillomavirus (HPV) testing in predicting patients who should undergo high-resolution anoscopy for the early detection of anal cancer and anal intraepithelial neoplasia (AIN)-2+. METHODS: We conducted a prospective single-center quality improvement study. We consecutively enrolled men who had sex with men (MSM) attending our sexually transmitted disease clinic to undergo anal Papanicolaou (Pap) and HPV tests. All patients with an abnormal anal Pap test result and/or positive HPV test result underwent high-resolution anoscopy. RESULTS: We enrolled 217 MSM, 80 HIV-positive patients, and 137 HIV-negative patients. Cytology showed a sensitivity of 100%, a specificity of 64.1%, an accuracy of 66.7%, a positive predictive value (PPV) of 15.7%, and a negative predictive value (NPV) of 100% for the detection of AIN-2+. The high-risk (HR)-HPV test showed sensitivity, specificity, accuracy, PPV, and NPV of 100%, 36.4%, 40%, 9.4%, and 100%, respectively. The combination of abnormal cytology with identification of infection by at least 1 HR-HPV strain on the HPV test had a sensitivity of 100%, a specificity of 73%, an accuracy of 74.6%, a PPV of 19.1%, and an NPV of 100%. CONCLUSION: Anal HR-HPV testing, complementary to cytology, improves the diagnostic accuracy of screening for anal cancer.

Liquid-based anal cytology as a screening tool for prevention of anal cancer in at-risk populations: a single-center retrospective analysis on 111 patients

Objective: Squamous cell carcinoma of the anus (SCCA) is associated with human papillomavirus (HPV) infection in almost 90% of the cases. Its incidence is alarmingly high among men who have sex with men (MSM) and continues to increase at an average rate of 2% per year. The objective of the present study is to evaluate the usefulness and performance of liquid-based anal cytology as a screening tool for prevention and early detection of SCCA in a cohort of at-risk men. Method: We conducted a retrospective study including 111 MSM, aged between 22 and 62 years old, who underwent anal cytological screening with a liquid-based Pap test at our sexually transmitted diseases (STDs) clinic from January 2015 to March 2017. Results: Out of 111 anal smears, 57 (51,4%) resulted negative, 42 (37,8%) abnormal, and 12 (10,8%) unsatisfactory for the cytological evaluation. Only patients with an abnormal cytology underwent anoscopy and subsequent biopsy. The histological results were as follows: negative for squamous intraepithelial lesion (SIL) in 5 cases, low-grade SIL (L-SIL) in 21, high-grade SIL (H-SIL) in 5, SCCA in 1. Five patients had a normal anoscopy and biopsy was not taken. Conclusion: Liquid-based cytology, reducing the "darkening factors" typical for the conventional smears, has a higher positive predictive value than the traditional technique. Moreover, a cytological diagnosis of atypical squamous cells of undetermined significance (ASC-US) or L-SILmay hide a severe dysplasia or even a carcinoma. Thus, all patients with an abnormal anal cytology at any grade should be considered for anoscopy. (AU)

Photodynamic therapy with topical photosensitizers in mucosal and semimucosal areas: Review from a dermatologic perspective.

Photodynamic Therapy is a procedure based on the interaction between a Photosensitizer, a light source with a specific wavelength and oxygen. The aim of this review is to provide a brief and updated analysis of scientific reports on the use of PDT with topical PS in the management of oncological, infectious, and inflammatory disorders involving mucosal and semimucosal areas, with a specific focus on diseases of dermatologic interest.

Pap smear in the prevention of HPV-related anal cancer: preliminary results of the study in a male population at risk.

BACKGROUND: The aim of this work was to evaluate the role of human papillomavirus (HPV) testing and anal cytology, considering a population of HIV-positive and negative men who have sex with men (MSM), at high risk of sexually transmitted diseases (STD), in order to ascertain which of the methods examined is the best screening strategy for the prevention of anal cancer. METHODS: In the period 06/2013-07/2014 at the "MTS Centre" of the University of Florence, 87 male patients, homo/bi-sexual, of which 46 HIV-negative and 41 HIV-positive, were recruited for anal Pap smear and HPV testing. All patients with an "abnormal" cytological result underwent anoscopy with possible biopsy. RESULTS: HPV testing was positive in 73 patients (83.6%). Cytology was negative in 50 patients (57.5%), inconclusive in 14 patients (16.1%), abnormal in 23 patients (26.4%): 14 ASC-US (19.2%), 4 ASC-H (5.5%), 5 L-SIL (6.8%), 0 H-SIL. Anoscopy with biopsy led to diagnosis of AIN I in 10 cases, of which 6 ASC-US+ and 4L-SIL+, AIN II in only 1 case, LS-IL+. CONCLUSIONS: Anal HPV testing, when used in primary screening, lead to a high number of "false positives", given the too high prevalence of HPV infection in MSM, the highest risk population targeted for screening. So we propose a screening program with anal cytology which has a high sensitivity for detection of AIN while is a poor predictor of the severity of these lesions; therefore, all patients with abnormal anal Pap smear should undergo anoscopy with biopsy.

Mycetomatoid infection of the penis by Candida albicans.

BACKGROUND: Mycetoma is generally understood to be a chronic suppurative infection involving the skin and the underlying tissue. Mycetomas may be classified as those produced by true fungi (eumycetoma) versus those due to aerobic bacteria Actinomycetales (actinomycetoma). METHODS: We report the atypical case of a mycetomatoid infection of the penile shaft and glans in a 36-year-old man, originally from Senegal, affected by Takayasu's arteritis. RESULTS: Extensive investigations excluded any other causative pathogen other than Candida albicans, and the ailment accordingly healed after fluconazole monotherapy. CONCLUSION: The authors discuss the unusual site of the disease and the singular clinical features related to the fungal etiology and put forward considerations on the pathogenic role of common microorganisms.

Primary anetoderma and HIV infection: a case report.

Anetoderma is characterized by circumscribed areas of flaccid skin caused by the loss of elastic tissue in the dermis. It may be primary or secondary to various dermatoses. The primary form has been reported in patients with autoimmune diseases, increased levels of antiphospholipid antibodies, prothrombotic abnormalities, and recently, HIV-1 disease. The origin of anetoderma remains unknown. A case of primary anetoderma is reported in a 45-year-old man with asymptomatic HIV-1 infection who was receiving antiretroviral therapy. Laboratory research included the classic immunologic investigations and screening for prothrombotic abnormalities. Possible pathogenic mechanisms of anetoderma, especially with respect to HIV-1 infection and antiretroviral therapy, are discussed.

Pruritus ani.

In the anal region, pruritus may be both idiopathic (mainly of psychological/psychiatric origin) and secondary to an underlying disorder or related to local causes (mainly of dermatologic interest). Persistent pruritus ani is, in particular, a challenging experience for the dermatologist.
