Study Objective: To demonstrate the prevalence of endometriosis in the intrapelvic portion of the round ligaments of the uterus (RLUs) and to propose criteria for their excision. Design: Retrospective case series analysis of women undergoing laparoscopy for the treatment of deep infiltrating endometriosis (Canadian Task Force classification II-3). Setting: Tertiary referral hospital. Patients: We evaluated 174 patients who underwent laparoscopy for the treatment of deep infiltrating endometriosis (DIE) between April 2006 and May 2009. Interventions: All patients underwent laparoscopy for the treatment of DIE and had their RLUs removed when there was shortening, deviation, or thickening. After removal, the RLUs were sent for histopathologic analysis to verify the presence or absence of endometriosis. Measurements and Main Results: The prevalence of endometriosis in the RLUs and the association between the macroscopic alterations and the anatomic pathology results were determined. After the identification of macroscopic alterations, 1 or both RLUs (for a total of 42) were removed from 27 of the 174 patients who underwent laparoscopy. The positive predictive value (PPV) of the macroscopic criteria proposed for endometriosis of the RLU was 83.3% (95% confidence interval [CI] = 72.1%-94.5%), with 35 positive RLUs out of the 42 that were excised. The prevalence of endometriosis of the RLU was 13.8% (95% CI = 8.7%-18.9%), with 24 patients having a positive histopathologic examination result for endometriosis. Conclusions: The prevalence of RLU endometriosis in patients with DIE was 13.8%, which emphasizes that a rigorous evaluation of this structure must be part of the routine surgical treatment of patients with endometriosis. © 2012 AAGL.

Human papillomavirus (HPV) is the main etiologic agent of lower genital tract cancers. The natural history of HPV infection and the immune response to HIV/HPV co-infection, particularly in the anal mucosa, is poorly understood. The aim was evaluate the in situ immune response in anorectal biopsies from HIV-infected patients. A total of 114 biopsies were analyzed by Tissue Micro-Array: 15 were from HIV-negative individuals with normal squamous epithelium and 99 from HIV-positive individuals (21 normal squamous epithelium, 39 with anal intra-epithelial lesion grade 1 and 39 with anal intra-epithelial lesion grade 2/3). PCR and sequencing were used to identify HPV DNA. Staining for CD4, CD8, Foxp3+, T-bet and IL-10 were analyzed via immunohistochemistry. HIV-positive patients with AIN 2/3 showed a lower number of CD4+ cells (< 50 cells/mm3) compared to HIV negative subjects (P = 0.01). HIV infected individuals showed a higher expression of FoxP3+ and IL-10 that correlated with the severity of the lesion (P = 0.002). A positive coefficient correlation was found between FoxP3+ and IL-10 (r = 0.34; P = 0.027). HPV DNA was detected in 93.4% (101/107) of the samples and the most common types were HPV 16 (26.9%), followed by HPV 6 (15.7%), HPV 59 (13%) and HPV 18 (10.2%). Our results showed a strong association between the increased T-reg cells and IL-10 expression in HIV-positive patients with AIN 2/3. HPV 16 was the most prevalent type. Our study suggests that the immune regulatory in situ profile may favor HPV persistence in HIV-positive individuals. Further in situ studies should be done in order to elucidate the development of anal cancer in HPV/HIV co-infected individuals. Source

This study was undertaken to better understand clinical characteristics, environmental and physical events in Down syndrome (DS) and alopecia areata (AA). This cross-sectional study included 18 DS patients who were currently presenting or had presented AA. We evaluated gender, age, location and type of AA, presence of autoimmune disease or atopy, AA in first-degree relatives, and environmental, physical, and clinical intercurrences. The mean age of study subjects was 11.6 (SD ± 5.5) years and mean age at AA onset 7.2 (2.5 to 15.2) years. The duration of alopecia episodes varied, with a mean of 2.7 (0.1 to 18.7) years. Recurrence of AA was reported in 27.7% (5/18) of subjects, with a mean number of recurrences of 3.6. Localized type AA was seen in 83.4% of individuals, with the most frequent location on the scalp (100%). Seven of the individuals presented atopy. Fourteen individuals had undergone environmental and/or clinical intercurrences. In conclusion, the most frequent presentation of AA in DS is the non-recurrent, localized form on the scalp, with a varied period of duration. Changes in the individuals' routine occurred in more than half of the study group. We suggest further studies of the psychology and immunogenetics in the etiopathology of AA in DS. Source

Objectives: To estimate the incidence of genital warts in adolescents and analyze their relationship with the development of cervical squamous intraepithelial lesions (SIL). Study design: From 1993 to 2006 we followed 846 adolescents in the gynecology clinic of a public hospital in Rio de Janeiro. They were sexually active, had a normal smear test and no genital warts upon recruitment and completed two years of follow-up. Data were analyzed using EPI-INFO software. The research was approved by the hospital Ethics Committee. Results: The mean age at recruitment was 15.8 ± 1.4 years and at first intercourse was 14.7 ± 1.6. Sixty-three (7.4%) adolescents presented condylomata, 5.6% (48/846) during the first year of sexual activity and 1.8% (15/846) during the second year. Within two years, 20.5% (174/846) of the patients had an abnormal smear test. Seventy percent (44/63) of the patients with genital warts developed a SIL. The association between warts and SIL showed a RR = 4.2(3.3-5.3). Conclusions: The incidence of condylomatawas one third of the incidence of SIL and was higher during the first than in the second year of sexual activity. Adolescents with genital warts had a fourfold increase in risk of SIL and therefore should be carefully followed up. © 2013 Elsevier Ireland Ltd. All rights reserved. Source

Our objective was to describe the evolution of cervical SIL within 24 months of the initial diagnosis, in a cohort study of 147 sexually active adolescents attending a public health service in Rio de Janeiro, between 1993 and 2006. The participants were divided in two groups, according to whether cervical biopsy was performed or not. The median of the interval between sexual debut and the atypical cytopathology was 12 months and in 8.2% of patients there was a diagnosis of HSIL at the first abnormal smear. After a two-year follow-up by cytology, the regression (ASCUS 91%, LSIL 63.6%, HSIL 50%) and progression (LSIL 6.1%) were verified. In the group undergoing biopsy, the final histological regression reached 59.4% for CIN1 and 71.4% for CIN2, while the progression from CIN1 to CIN 2/3 was 3.1%. Our results corroborate the recommendation for conservative management in compliant adolescents due to a high regression rate. However, there should be maintained a careful follow-up based on the possible evolution of the lesion. © 2010 North American Society for Pediatric and Adolescent Gynecology. Source
