Background: Anal intraepithelial lesions (AIL) are likely to represent a precursor for anal cancer. Women infected with human immunodeficiency virus (HIV) may be at higher risk of anal cancer but a screening program for AIL still is not routinely recommended. We here studied the relationship of dysplastic cells from cervical and anal cytology in HIV-infected women. Materials and Methods: This prospective study was conducted in Prapokklao Hospital, Thailand during 2013-2014. Five hundred and ninety nine HIV-infected women were recruited. Participants who had cytological reports of equally or over "abnormal squamous/glandular cells of undetermined significance" (ASC-US) were classified as abnormal cervical or anal cytology. Descriptive statistics and logistic regression analysis were used to evaluate correlations between groups. Results: HIV-infected women with abnormal cervical cytology had 3.8 times more risk (adjusted odd ratio 3.846, 95% confidence interval 1.247-11.862, p-value. 019) for abnormal anal cytology. The major problem of the anal Pap test in this study was the inadequacy of the collected specimens for evaluation (34.4%, 206/599). Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of cervical and anal Pap tests were 93.9/12.0, 87.3/96.9, 39.7/21.4, 99.4/94.1 and 88.1/91.4 percent, respectively. Conclusions: Abnormal cervical cytology in HIV-infected women indicates elevated risk for abnormal anal cytology. The sensitivity of the anal Pap test for detection of AIL 2/3 in HIV-infected women was quite low while specificity was excellent. Inadequacy of specimen collection for evaluation was a major limitation. Improvement of sample collection is recommended for future investigations.

This study aimed to screen for anal cancer and to determine its cytomorphology using liquid-based cytology (LBC) with specimens preserved in 95% ethyl alcohol. Anal swabs were collected for cytological examination from 177 adult, HIV-infected patients. After collection, sample slides were reviewed and classified according to their cytomorphology using the modified Bethesda 2001 system. An abnormal anal Pap smear was found in 26.0% of the patients. The diagnoses were: 66.7% negative for intraepithelial lesions (NIL), 14.1% with atypical squamous cells of undetermined significance (ASC-US), 10.7% (19) with low-grade squamous intraepithelial lesions (LSIL), and 1.13% with high-grade squamous intraepithelial lesions (HSIL). The cytological evaluation was an unsatisfactory result only with 6.67%. The present modified LBC using 95% ethyl alcohol as the preservative could thus be used for anal cancer screening. The number of SILs in Thai HIV-infected patients is lower than that in Western countries. We found anal cytology a satisfactory tool for early screening and detection of anal dysplasia commonly found in high-risk, HIV-infected patients.

Background: To study the prevalence of abnormal anal cytology by Papanicolaou (Pap) technique in HIV-infected women who attended a HIV clinic at Prapokklao Hospital, Chanthaburi, Thailand. Materials and Methods: HIV-infected women who attended a HIV clinic at Prapokklao Hospital from March 2013 to February 2014 were recruited for anal Pap smears. Participants who had abnormal results of equally or over "abnormal squamous/glandular cells of undetermined significance" (ASC-US) were classified as abnormal anal cytology. Results: A total of 590 anal Pap smears were performed at HIV clinic of Prapokklao Hospital during the study period. There were only 13 patients who had abnormal Pap tests, which were: 11 ASC-US and 2 HSIL (high grade squamous intraepithelial lesion). The prevalence of abnormal anal Pap smears in HIV-infected women who attended HIV clinic at Prapokklao Hospital was 2.2 percent. Percentage of high risk HPV in patients who had abnormal Pap test was 88.9 (8/9). Conclusions: The prevalence of abnormal anal Papanicolaou smears in HIV-infected women who attended the HIV clinic at Prapokklao hospital was quite low in comparison to the earlier literature.

Five dogs diagnosed as apocrine gland adenocarcinoma (AGAC) of the anal sac based on cytology and/or histology. Mean age of these dogs was 11 years old. One dog treated with supportive care without other medical interventions for hypercalcemia was died one month after diagnosis. Other four dogs were treated with chemotherapy and one of these dogs was intervened with complete surgical resection. Two months after the diagnosis, one of the dogs treated with chemotherapy died. The survival time of other survived three dogs from the time of diagnosis was 19, 9, and 13 months respectively and they are still alive at this time. After chemotherapy, three dogs were managed generally in good body condition and maintained as similar in size as time of diagnosis. The results are suggested that it is worthwhile to try chemotherapy for managing AGAC in dogs especially complicated or metastasized to regional lymph nodes.
