RESUMO

OBJECTIVES: To assess the frequency of detection of high-risk human papillomavirus (hrHPV) on transvaginal ultrasound (TVS) probes and keyboards and evaluate operator compliance with national recommendations for prevention of cross-infection during TVS. METHODS: This was a multicenter observational survey involving 46 public and private centers, in the Paris region of France, in which at least five consecutive TVS examinations were performed per day. We audited 676 TVS procedures. We recorded preventive hygiene actions undertaken by the operator at three stages: (1) during TVS; (2) during probe disinfection; and (3) during preparation of the probe for the next TVS. After probe disinfection, we collected one sample from the bare probe and one from the ultrasound keyboard; following probe preparation for the next examination, an additional sample was obtained from the covered probe. The samples were tested for presence of hrHPV DNA using the Cobas® 4800 System. RESULTS: We did not detect hrHPV DNA in samples collected from uncovered or covered probes (0%; 95% CI, 0.00-0.55%). Keyboard samples were positive for hrHPV in two cases (0.3%; 95% CI, 0.04-1.07%). During TVS, the operator avoided touching the keyboard with a hand that had touched the patient's vulva in 86% of cases and held the probe with a gloved hand in 68%. Before probe disinfection, the operator wore new gloves, or performed hand disinfection in 8% of cases. The probe disinfection technique used was adequate in 87% of cases, not performed at all in 12% and insufficient in 1%. Before preparing the probe for the next scan, the operators disinfected their hands or used new gloves in 81% of cases. The probe cover and the coupling gel used complied with recommendations in 98% and 46% of cases, respectively. Of the seven preventive hygiene actions recommended in national guidelines, all were performed in 2%, three to six in 95% and two in 3% of observations. In four (9%) centers, disinfection was not performed in over half the observations. CONCLUSIONS: No evidence of hrHPV DNA was found on TVS probes and probe covers following low-level disinfection, despite suboptimal compliance with hygiene guidelines. Routine TVS practice could be made easier and safer with a global approach to probe disinfection and hand hygiene. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

RESUMO

OBJECTIVES: Head and neck squamous cell carcinoma (HNSCC), mainly due to smoking, is one of the leading causes of cancer deaths. However, an increasing number of tumors - especially oropharyngeal cancer - are reported in non-smokers in association with the human papillomavirus (HPV). As HIV-infected individuals are particularly at risk of HPV-related disease, we aimed to describe the burden of HNSCC in this population. METHODS: Retrospective chart review of patients from HIV clinics diagnosed with HNSCC between 2004 and 2014. Case patients were defined using the International Classification of Disease for Oncology (3rd edition). Age at HIV diagnosis and time from HIV diagnosis to HNSCC diagnosis were collected. Oropharyngeal cancers were considered as potentially HPV-related cancers, and their prevalence was compared with other HNSCCs over time. RESULTS: The 286 patients enrolled in the study had a median age at HNSCC diagnosis of 52 years; 84% were males and 68% had a history of smoking. The oropharynx was the most frequent site (41%), followed by cancer of the oral cavity (31%), larynx (22%), and hypopharynx (7%). The prevalence (and proportion) of potentially HPV-related cancers increased significantly over time with a mean of 0.78 additional case patient per year. CONCLUSION: The prevalence of HNSCC is modest compared with other cancers in HIV-infected individuals. The prevalence of oropharynx carcinoma, a potentially HPV-related carcinoma, seems to increase over time. Even if tobacco may be an important contributor, the role of HPV in HIV-infected individuals presenting with HNSCC should be investigated.

RESUMO

BACKGROUND: The benefit of HPV testing for cervical cancer screening and disease management has been shown in many recent studies and is part of several new evidence-based guidelines. Assessment of emerging HPV tests in this context is essential, using well-annotated samples, such as those generated via the Validation of Genotyping Tests-HPV (VALGENT) framework. OBJECTIVE: Our aim was to assess the PapilloCheck HPV assay in terms of absolute and relative accuracy for primary cervical cancer screening, using a standard comparator test (GP5+/6+EIA)already validated in randomised trials. STUDY DESIGN: Type-specific HPV prevalence was stratified by age and cytology grade and compared with the luminex typing assay incorporating a GP5+6+ PCR (GP5+/6+ LMNX Assay). Clinical outcomes were compared with GP5+/6+EIA. RESULTS: Prevalence of hrHPV types (high-risk HPV) increased with severity of cytology. The concordance between PapilloCheck and the GP5+/6+ LMNX Assay was excellent when assessed at the qualitative hrHPV presence/absence level also at the type-specific level in the whole population and in women over 30 years of age. Absolute clinical sensitivity and specificity of the PapilloCheck was high and ranged between 95.5% and 98.2% for sensitivity and between 82.7% and 91.6% for specificity, depending on the outcome and population. CONCLUSION: The sensitivity and specificity of this assay for the outcomes of CIN2+ were similar to those of the standard comparator assay, GP5+/6+ EIA.

RESUMO

OBJECTIVES: Our objectives were to determine the reproducibility of cytological specimen interpretation between two pathologists in human immunodeficiency virus (HIV)-infected women (from the VIHGY, ANRS CO17 study of human papillomavirus genital pathology among HIV-positive women) and to analyse the improvement, if any, between conventional and liquid-based cytology (LBC) interpretations. MATERIALS AND METHODS: A sample of all abnormal and 40% of randomly selected normal Papanicolaou (Pap) tests was randomly ordered and read blindly by a second pathologist using the revised Bethesda terminology 2001. For both conventional and liquid-based preparations, unweighted and Cicchetti-Allison-weighted kappa and their 95% confidence intervals (CIs) were calculated. Kappa values were then compared using the Altman rule to classify the reproducibility of cytological specimen interpretation. RESULTS: Two hundred and seventy-seven conventional Pap tests were reviewed, including 79 abnormal and 10 unsatisfactory results. Overall agreement between the two observers was 78%, with an estimated Cicchetti-Allison-weighted kappa of 0.69 (95%CI, 0.61-0.77). The corresponding values for the 268 LBCs, including 123 abnormal and two unsatisfactory results, were 84% and 0.82 (95%CI, 0.76-0.87), respectively. The reproducibility of LBC interpretations was significantly higher than that of conventional preparations (P = 0.009) and, for both laboratories, the percentages of unsatisfactory results were significantly lower for LBC. CONCLUSION: In HIV-infected women in the combination antiretroviral therapy era, the strength of agreement was better for LBCs than for conventional preparations, with a lower percentage of unsatisfactory results. When available, LBC should be preferred because of its higher reproducibility.

RESUMO

While the use of endovaginal ultrasound probes is increasing, the risk of contamination of women with endocavity vaginal probes was not assessed. In particular, the clinical significance of detection of human papillomavirus (HPV) infection, the most common sexually transmitted viral infection, on endovaginal ultrasound probes is uncertain. The recommendations of good practice for decontamination of these probes developed by the High Council for Public Health and the Academy of Medicine have not been evaluated. The objective of this article was to review recent publications concluding to the detection of HPV and human cellular DNA after gynecological examination and disinfection of vaginal ultrasound probes.

RESUMO

OBJECTIVE: The objectives of the study were to investigate high-risk human papillomavirus (HR-HPV) infection and type distribution in women infected with HIV-1, and to determine the relevance of HR-HPV positivity and persistence/loss to the development of high-grade cervical disease. DESIGN: A total of 518 European women infected with HIV attending for routine gynaecological care consented to 6-monthly follow-up visits over 3 years, with surveillance of cytology, colposcopy and histopathology, where relevant, and longer follow-up, where possible. SETTING: European women infected with HIV attending for routine gynaecological care. POPULATION OR SAMPLE: 518 European women infected with HIV attending for gynaecological care in 6 hospital-based European centres - Dublin, Edinburgh, London, Milan, Paris, and Warsaw. METHODS: Cervical screening was achieved by liquid-based cytology (LBC) of brush samples in PreservCyt® medium. The HPV testing of residual samples was performed by Hybrid-Capture II, with genotyping of positives using the HPV Line Blot Assay. Histology results were accessed where available. MAIN OUTCOME MEASURES: Description of high risk human papillomavirus (HR-HPV) infection and type distribution in HIV-1 infected women. RESULTS: The estimated prevalence at baseline of any HR-HPV type was 49.5% (46.3-52.8%): 10.2% for HPV 16 and 4.3% for HPV 18. The prevalence increased with increasing immunosuppression. Multiple infections were detected in 26.8%. HR-HPV genotypes were detected in 34.9% of cases with normal cytology, in 77.2% of cases with atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion (ASCUS/LSIL) and in 90.8% of cases with high-grade SIL (HSIL). The prevalence of HPV 16 in HSIL was 38.5%, with the three most common types thereafter having prevalence rates of 19.2% (HPV 58), 19.2% (HPV 53) and 16.6% (HPV 52). The overall persistence of any high-risk type was 55.8%. We found that 6 months persistence of HPV 16 occurred in 24 women. Seven cases of high-grade cervical disease developed, and all were associated with initial/persistent HR-HPV positivity. CONCLUSIONS: A wide diversity of HPV types was evident, and multiple infections were common. Detection or persistence of any HR-HPV was associated with a very low incidence of subsequent high-grade disease.

RESUMO

BACKGROUND: The literature contains conflicting findings on the influence of gender and HIV transmission group on the initial prescription of highly active antiretroviral therapy (HAART) and its biological and clinical efficacy. METHODS: We conducted a cohort study involving 62 French hospitals. We used Cox proportional hazards models to examine whether gender and HIV transmission group influenced the timing of elective HAART initiation, and the clinical and biological response to treatment. RESULTS: We studied 5735 patients enrolled between January 1997 and December 2001 who did not start HAART or develop a stage C HIV-related event during the first 3 months after inclusion. In multivariate analysis, no gender differences were found in the interval between enrollment in the database and HAART initiation, but this interval was shorter in homosexual patients than in other transmission groups; CD4 cell counts at treatment initiation were also higher in the homosexual group. The immunovirological response to treatment did not differ according to gender, but was better in homosexual patients than in patients in other categories. Injecting drug users had the weakest immunovirological responses. Clinical outcome was not related to gender or to HIV transmission group. CONCLUSIONS: The interval between diagnosis of HIV-1 infection and elective HAART initiation was not influenced by gender. However, homosexual patients had higher CD4 cell counts than other patients at treatment initiation, and also had better immunovirological responses.

RESUMO

Current socio-behavioural research in HIV-infected people has tried to identify patients with "high-risk" profiles, i.e. who simultaneously exhibit non-adherence to highly active anti-retroviral therapy (HAART) and unsafe sex with serodiscordant partners. We challenged this approach by investigating the correlates of both behaviours, for homosexual men, heterosexual men and heterosexual women separately, among a representative sample of 4963 HIV-infected people in France. Variables introduced in the analysis dealt with patients' background and daily life, with a focus on situations of economic, social and personal vulnerability. Overall, 2932 patients agreed to participate, and 1809 were both receiving HAART and sexually active. Among heterosexual women, non-adherence and unsafe sex appeared as joint outcomes of similar situations of vulnerability. Among heterosexual men, these behaviours were weakly correlated and shared some predictors related to situations of vulnerability. Among homosexual men, non-adherence and unsafe sex were not correlated and had distinct determinants. Situations of vulnerability, the context and the motives of unsafe sex, as well as factors associated with non-adherence and unsafe sex varied greatly with gender and sexual preference. Theoretical models used for designing behavioural interventions should take into account this diversity.

RESUMO

Human papillomaviruses (HPV) are the most prevalent sexually-transmitted agents worldwide. HPV are small circular double-stranded DNA epitheliotropic viruses that exhibit either cutaneous or mucosal specificity. Most HPV infections are self-limiting and are spontaneously cleared within months or years. However, infections may persist and result in a variety of benign, pre-malignant and malignant tumors. Cytological and histopathological abnormalities associated with HPV infections of the male and female lower anogenital tract include condylomata, low-grade and high-grade squamous intraepithelial lesions which are incipient cancers, and squamous cell carcinomas. The modal time between HPV infection occurring in the late teens or early 20 s and precancer peaking around 30 years of age is 7-10 years. Women detected with invasive cancers tend to be an average 10 years older than women with high-grade disease. The natural history of cervical cancer reveals that infection with high-risk types may lead to low-grade or high-grade intraepithelial lesions. High-grade lesions may progress to cervical carcinoma if not treated. The purpose of screening, in addition to detecting cervical cancers at an early stage, is to detect and remove high-grade lesions and thus prevent the potential progression to cervical carcinoma. Early detection of cervical neoplasia is possible with regular Pap smears performed from 21 to 70 years of age. In case of abnormal Pap smear, a biopsy performed under colposcopy will allow the diagnosis of cervical lesion. Cancer of the cervix is the second leading cause of cancer related deaths among women across the world (3,400 new cases in France in 2000).

RESUMO

BACKGROUND: Couples in whom the man is infected by human immunodeficiency virus (HIV) increasingly request assisted reproductive technology (ART) to allow safe procreation. Semen quality is critical in such situations. METHODS: Semen characteristics were evaluated in 189 HIV-infected men requesting ART. At the time of semen analysis all men were healthy and 177 were receiving anti-retroviral therapy. Comparisons were made with HIV-seronegative men, partners of women requiring IVF because of tubal infertility, after matching for age and sexual abstinence delay. RESULTS: The most significant semen alterations found in the HIV-infected men were reduced percentages of rapidly progressive sperm [median (range), 10% (0-30%) compared with 15% (5-30%) in the controls, P < 0.001], and increased concentrations of non-spermatic cells [3 x 10(6)/ml (0.2-16 x 10(6)/ml) compared with 1.1 x 10(6)/ml (0.1-14 x 10(6)/ml) in the controls, P < 0.001]. HIV-infected men also showed lower ejaculate volumes [2.8 ml (0.6-9.3 ml) compared with 3.6 ml (1.1-11 ml), P < 0.05] and total sperm counts [262.5 x 10(6) (0-1003 x 10(6)) compared with 310.5 x 10(6) (48.3-1679 x 10(6)), P < 0.05]. CONCLUSIONS: Semen evaluation in a large population of HIV-infected men requesting ART evidenced several alterations. Some of these anomalies might be related to anti-retroviral treatments.

RESUMO

OBJECTIVE: To investigate human papillomavirus (HPV) genotypes, HPV DNA load, and behavioral and sociodemographic factors in a series of human immunodeficiency virus (HIV)-seropositive women, and to correlate HPV infection with cervical disease according to immune status. METHODS: Three hundred seven HIV-seropositive women were tested for the presence of HPV DNA by polymerase chain reaction (PCR) and Southern blot hybridization. Cervical disease was assessed using Papanicolaou smears, colposcopy, and biopsies when necessary. Various risk factors for cervical intraepithelial neoplasia (CIN) were tested using multiple logistic regression analysis. RESULTS: Cervical disease was diagnosed in 83 (27.0%) of 307 women and HPV infection in 162 (52.8%). High HPV load (as detectable by Southern blot hybridization) was found in 90 (55.6%) of the 162 infected women. Potentially oncogenic or related genotypes were detected in 74 (82.2%) of these 90 cases. High-load HPV infection was twice as frequent in severely immunosuppressed women (CD4 cell count less than 200/microL) as in women with higher CD4 cell counts (P =.002). High-load HPV infection was associated with a high risk of cervical disease (adjusted odds ratio [OR] 16.8; 95% confidence interval [CI] 7.0, 40.3). The risk among severely immunosuppressed women was ten times greater than that among women with CD4 cell counts of at least 200/microL. Low-load HPV infection (detected by PCR only) was a risk factor for CIN in severely immunosuppressed women only (adjusted OR 7.4; 95% CI 1.3, 43.0). CONCLUSION: Immunosuppression favors cervical high-load HPV infection with oncogenic genotypes and its clinical expression in HIV-seropositive women.

RESUMO

We investigated human immunodeficiency virus (HIV) type 1 RNA, proviral DNA, and antiretroviral drug-resistant variants in cervicovaginal secretions of HIV-1-infected women receiving antiretroviral therapy. The prevalence of detectable HIV-1 RNA in genital secretions was inversely related to the number of antiretroviral drugs taken by the patients. Proviral DNA was detected in approximately half of all samples of cervicovaginal secretions from HIV-1-infected women, regardless of the presence or absence of HIV-1 RNA in cervicovaginal secretions and of the antiretroviral regimen. In cervicovaginal secretions of most women with persisting genital viral replication, HIV variants exhibiting mutations associated with drug resistance against protease and reverse-transcriptase pol genes were found. Our observations indicate that antiretroviral therapy is not effective in purging the female genital tract of cell-associated provirus and that antiretroviral drugs that penetrate the female genital tract at suboptimal concentrations exert a potent selective pressure on genital HIV variants when local replication of free HIV-1 RNA persists.

RESUMO

BACKGROUND: To assess HIV burden in both acellular and cellular fractions of semen in men with different levels of blood plasma HIV RNA by a cross-sectional study. PATIENTS: Fifty-two HIV-1-seropositive men (21 receiving antiretroviral therapy) with CD4 cell counts ranging from 1 to 1170 x 10(6)/l. METHODS: Semen was separated into seminal plasma and fractions enriched in motile spermatozoa or non-spermatozoal cells. HIV RNA was quantified by the HIV-Monitor technique (Roche) in blood plasma, seminal plasma and spermatozoa fractions. HIV DNA or infectious virions in cellular fractions were detected by either PCR or qualitative viral culture. RESULTS: HIV RNA was detected in 86.5% of seminal plasma specimens and in 14.6% of spermatozoa fractions; HIV DNA was detected in 57.1% of non-spermatozoal cell fractions. HIV RNA levels in blood plasma and seminal plasma were correlated (r5 = 0.56, P < 0.0001, Spearman's rank test). A majority of men had lower levels in seminal plasma than in blood plasma: one-third had HIV-positive seminal cell fractions. However, 20 men (38.5%) with HIV RNA levels in seminal plasma (median: 4.65 log10 copies/ml) comparable to or higher than those in blood plasma had all HIV-positive non-spermatozoal cells or spermatozoa fractions with a high frequency of positive cultures. CONCLUSION: A high frequency of men had detectable HIV in semen. We identified a subpopulation demonstrating high levels of HIV RNA in seminal plasma, comparable to or higher than those in blood plasma, frequently associated with a substantial viral shedding in seminal cells, raising the possibility of viral production within the genital tract and suggesting heterogeneity in the potential of HIV sexual transmission among infected men.

RESUMO

OBJECTIVE: Advanced HIV disease is associated with a high prevalence of cervical squamous intra-epithelial lesions (SIL) and of infection with oncogenic human papillomavirus (HPV) genotypes. Triple-combination antiretroviral therapy results in decreased plasma HIV viral load, increased CD4 cell counts and partial restoration of immune functions in patients with severe HIV disease. This study investigated the outcome of SIL in HIV-seropositive women undergoing triple combination antiretroviral treatment. METHODS: Forty-nine women who started triple-combination antiretroviral therapy, including a protease inhibitor, were examined prior to and after a median 5-month treatment. We collected cytological, colposcopic and histologic data and assessed the presence of HPV DNA in cervical smears by PCR and Southern blot hybridization (SBH). RESULTS: The prevalence of SIL decreased from 69 to 53% during follow-up (P < 0.0001). Among 13 women who initially presented with high-grade SIL, conversion to lower grade was observed in two women and a full regression to normality was observed in one. Cytology also returned to normality in nine out of 21 women who initially presented with low-grade SIL. The high prevalence of HPV infection as detected by SBH and PCR was similar at the first and second examinations and the same high-risk viral genotypes were identified at both examinations in all infected patients but one. There was a higher increase in absolute CD4 cells in the subgroup of patients whose lesions regressed (99 versus 50 x 10(6)/l, P=0.03). CONCLUSION: Our observations demonstrate that active antiretroviral therapy may result in a reduced prevalence of cervical squamous intra-epithelial lesions despite the absence of clearance of HPV infection.

RESUMO

OBJECTIVE: To investigate the impact of HIV infection on the prevalence, incidence and short-term prognosis of squamous intraepithelial lesions (SIL), in a prospective study with 1-year follow-up. METHODS: Between 1993 and 1995, 271 HIV-positive and 171 HIV-negative women at high risk of HIV infection were recruited, 365 (82.6%) of whom completed the 1-year follow-up. The women underwent a Papanicolaou smear test at inclusion and at 6 and 12 months. Human papillomavirus (HPV) was detected at inclusion by Southern blot and PCR. RESULTS: The SIL prevalence ranged from 7.5% for HIV-negative to 31.3% for HIV-positive women with CD4 cell counts < 500 x 10(6)/l (P < 0.001). Other factors associated independently and significantly with SIL prevalence were HPV-16, 18, 33 and related types, HPV-31, -35, -39 and related types, lifetime number of partners, younger age, past history of SIL and lack of past cervical screening. The SIL incidence ranged from 4.9% in HIV-negative women to 27% in HIV-positive women with CD4 cells < 500 x 10(6)/l (P < 0.001). Progression from low- to high-grade SIL during follow-up was detected in 38.1% of HIV-positive women with CD4 cells < or = 500 x 10(6)/l but in no HIV-negative nor HIV-positive women with CD4 cells > 500 x 10(6)/l. HPV-16, 18, 33 and related types were also associated with higher incidence of SIL and progression from low- to high-grade SIL. CONCLUSION: HIV-induced immunodeficiency is associated with high prevalence, incidence and persistence/progression of SIL. A pejorative influence of HIV infection without marked immunodeficiency is less clear. HIV-positive women with SIL may thus benefit from early treatment when a useful immune response is still present.

RESUMO

HIV-infected women have a high prevalence of abnormal Papanicolaou smears and cervical intraepithelial neoplasia. A multiparametric analysis of epidemiological and behavioural risk factors has been performed in a cohort of 204 HIV-infected women in an outpatient clinic with the aim to investigate risk factors associated with squamous intraepithelial lesions (SIL) in HIV-seropositive women. The prevalence of SIL in the study population was 35.7%. Univariate and multivariate analysis of demographic, behavioural and immunological variables only identified cigarette smoking > 20/day and CD4+ cell counts < or = 200 x 10(6)/L as risk factors significantly associated with SIL in the study population. We found no epidemiological/behavioural risk factors specifically associated with SIL in HIV-infected women as compared with the general population. The results suggest that the high prevalence of SIL in HIV disease is related to acquired immune deficiency in HIV-seropositive women.

RESUMO

OBJECTIVE: To assess the outcome of cervical squamous intraepithelial lesions (SIL) in human immunodeficiency virus (HIV)-seropositive women. METHODS: Papanicolaou smears were followed-up prospectively in a group of 60 HIV-positive women every 6 months for 18 months. RESULTS: The cumulative incidence of SIL at 18 months was 9% in 27 women who presented with normal Papanicolaou smears at entry. In 33 women who initially presented with SIL, the rate of persistence of cervical lesions was 95% (18 of 19) in untreated patients and 61% (eight of 13) in women who underwent surgery. In women with low-grade SIL, the persistence or progression of cervical lesions was observed in 92% of the cases (12 of 13). No invasive cancer was observed during the 18 months of the study period. CONCLUSION: Although the long-term outcome of SIL in this population remains unknown, our results emphasize the high rate of persistence of SIL and the relative inefficiency of conventional treatment in HIV-infected women. These findings contrast with the natural history of SIL in immunocompetent women.

RESUMO

PIP: 354 women seeking abortions were treated at a hospital in Paris between February-September 1988 with 600 mg of RU 486 taken orally in 1 dose and an injection of 500 mg sulprostone 48 hours later. The women all had amenorrhea of less than 49 days. 1/3 were 18-25 years old, 1/2 were 25-35, and 16% were over 35. 206 were nulliparas. 110 were married and the rest were separated, widowed, divorced, or single. Sulprostone was injected early in the morning in the hospital and the women were discharged after expulsion of the products of conception, which occurred usually 2 1/2 to 3 1/2 hours later. If expulsion did not occur, the woman returned in 3 days for a sonogram to confirm uterine vacuity. 13 of the 354 women had RU 486 only. 2 refused the sulprostone and underwent aspiration and 11 experienced spontaneous expulsions in the 48 hours following RU 486 administration. 338 of the women had spontaneous expulsions. 2 pregnancies were terminated but not expelled and aspiration was required. 285 of the women expelled in the hospital within 4 hours of sulprostone administration and the other 55 did so at home 6 or more hours later. RU 486 was very well tolerated. Secondary effects were more common with sulprostone but generally subsided within 3 hours. 70 patients required treatment for uterine pain after sulprostone administration. 150 complained of nausea but only 6 required treatment. 5 women required aspiration of curettage for hemorrhage but none required transfusion. In 3 cases the hemorrhages were due to histologically proven retention. 1 patient developed endometritis 3 days after expulsion and another, who had a history of extrauterine pregnancy, developed salpingitis 15 days after expulsion. Both patients were treated with antibiotics. The method appears to be safe and effective. Its major disadvantages are that it prolongs the amount of time required for abortion and it frequently causes pelvic pain. The responsibility of the patient is also increased.^ieng
