RESUMEN
OBJECTIVE: Human PapillomaVirus (HPV) vaccination has been introduced in recent years in clinical practice as the most effective primary prevention strategy for cervical cancer and HPV-induced lesions, either pre-malignant or benign. Since its introduction, HPV vaccination has been progressively demonstrated as extremely effective in preventing extra-genital and male diseases also; furthermore, non only adolescents but adult subjects have been investigated and reported as positively responding to vaccine immunostimulation. More recently, effectiveness of post-treatment vaccine administration has been preliminarily investigated with very promising results in terms of decreased recurrences. On this basis, we report an Italian-focused picture of the state of the art and take a position in favour of the extension of HPV vaccination to male adolescents, to older age groups and to already treated subjects.

OBJECTIVE: To evaluate the effectiveness of a topical vaginal preparation containing hyaluronic acid in controlling signs and symptoms correlated with postmenopausal vulvovaginal atrophy (VVA). PATIENTS AND METHODS: A prospective, observational study has been performed at the Obstetrics and Gynecology Department of the Vita Salute San Raffaele University of Milan, Italy. Forty-six (46) consecutive postmenopausal women complaining of genital discomfort due to postmenopausal estrogen lack have been enrolled. All patients have been investigated by the use of the Vaginal Health Index (VHI) and of a Visual Analogic Scale (VAS) of symptoms at baseline and one month after the end of the study. The treatment protocol consisted of the administration of a hyaluronic acid-based liquid preparation for vaginal use (Justgin®, Just Pharma, Rome, Italy) three times a week, for a total of 8 weeks. Statistical analysis of VHI and VAS scores has been performed by the use of the Wilcoxon signed-rank test for repeated values, assuming a p-value < 0.05 as significant. RESULTS: Both Vaginal Health Index (VHI) and Visual Analogic Scale (VAS) of genital symptoms showed statistically significant (p < 0.0001) improvements at the end of the study protocol. Patients' degree of satisfaction at the end of treatment was reported as high. CONCLUSIONS: Conventional treatment of the postmenopausal syndrome, either in terms of systemic and genital symptoms, is based on hormonal replacement therapy (HRT). The limitations to this approach are represented by the need to discontinue the treatment after some years and the contraindications that some women present about the estrogens. For these reasons, alternative approaches have been recently investigated and indicate promising perspectives. Hyaluronic acid topical approach with a liquid preparation for vaginal use (Justgin®, Just Pharma, Roma, Italy) to control signs and symptoms of vulvovaginal atrophy (VVA) in postmenopausal women demonstrated significant effectiveness both in terms of objective and subjective improvement.

OBJECTIVE: To investigate the effects of fractional microablative CO2 laser on sexual function and overall satisfaction with sexual life in postmenopausal women with vulvovaginal atrophy (VVA). METHOD: This prospective study included 77 postmenopausal women (mean age 60.6 ± 6.2 years) treated for VVA symptoms with the fractional microablative CO2 laser system (SmartXide(2) V(2)LR, Monalisa Touch, DEKA, Florence, Italy). Sexual function and quality of life were evaluated with the Female Sexual Function Index (FSFI) and the Short Form 12 (SF-12), respectively, both at baseline and at 12-week follow-up. A 10-mm visual analog scale was used to measure the overall satisfaction with sexual life and the intensity of VVA symptoms (vaginal burning, vaginal itching, vaginal dryness, dyspareunia and dysuria) before and after the study period. RESULTS: We observed a significant improvement in the total score and the scores in each specific domain of the FSFI at 12-week follow-up compared to baseline (p < 0.001). After concluding the laser treatment, the overall satisfaction with sexual life significantly improved (p < 0.001). Seventeen (85%) out of 20 (26%) women, not sexually active because of VVA severity at baseline, regained a normal sexual life at the 12-week follow-up. Finally, we also found a significant improvement in each VVA symptom (p < 0.001) and in quality-of-life evaluation, both for the scores in the physical (p = 0.013) and mental (p = 0.002) domains. CONCLUSIONS: Fractional microablative CO2 laser treatment is associated with a significant improvement of sexual function and satisfaction with sexual life in postmenopausal women with VVA symptoms.

AIM: The aim of this study was to determine the efficacy of a new topic non-hormonal treatment for postmenopausal women complaining of symptoms of vaginal atrophy. METHODS: Patients included in the study were prescribed Sinecol gel (AM PHARMA Srl, Vimercate, Monza and Brianza, Italy) application once a day for 20 consecutive days. Sinecol gel is a topic compound for vaginal atrophy containing hyaluronic acid, that is known to improve vaginal elasticity, lactoperoxidase, Xantham gum and glucose oxidase, which have protective and antibacterial action. We evaluated each patient before and after treatment, both subjectively with the "Visual Analogical Scale" (VAS) and objectively with the "Vaginal Health Index" (VHI). RESULTS: We observed a significant clinical improvement of the subjective and objective assessment of symptoms severity with a p value <0.001 at the end of the treatment compared to baseline. CONCLUSION: Sinecol gel appears to be an effective and valid non-hormonal alternative to the estrogen therapy for vaginal atrophy.

OBJECTIVES: Cervical cancer is the most commonly diagnosed malignancy in pregnancy and cervical screening should be accordingly performed in this particular situation. Occurrence of a preneoplastic cervical disease in pregnancy has for a long time represented a challenge for the clinician, both in terms of diagnostic accuracy, treatment options and risk of obstetrical complications. For these reasons, lack of uniformity in diagnosis and management is still commonly observed and the need for evidence-based clarifications is strongly required. Consistently with the literature evidences and accordingly with international guidelines, this review aim to overview the most significant aspects of the issue and trace simple and practical indications for an evidence-based correct workout and management of these conditions. MATERIALS AND METHODS: The most significative and focused-on results from literature as well as recent international guidelines have been considered and summarized in order to clarify the key-points of the topic; epidemiology, pathophysiology, natural history, treatment modalities and procedure-related risks have been approached and discussed. RESULTS: Risk factors, prevalence and progression rate of cervical intraepithelial neoplasia in pregnancy are comparable to those observed in non-pregnant patients; thus, pregnancy does not have to be considered a condition at higher risk. Cytology, histology and colposcopic patterns must be evaluated by experienced professionals because of pregnancy-induced modifications that can lead to misinterpretations. Each diagnostic step should be directed to exclusion of invasive cervical cancer. CONCLUSIONS: Once invasive cancer has been excluded through a comprehensive diagnostic workout, treatment of cervical intraepithelial neoplasia can be safely deferred after delivery.

OBJECTIVES: Human papillomavirus (HPV) is the causal agent of cervical cancer. The great majority of abnormal Pap test results - almost 90% - is referrable to either atypical squamous intraepithelial lesion or CIN1. For these lesions, worldwide agreement exists concerning the high rate - ranging from 40% to 70% - of spontaneous regression over a period of 1-5 years. Host's immune response is a key point influencing the natural history of these conditions. Bovine colostrum is a natural agent positively promoting several immune activities against bacterial and viral agents. The aim of this report was to evaluate the potential positive effect of bovine colostrum-containing vaginal tablets administered to CIN1 diagnosed patients in a prospective trial in regards to spontaneous regression rate. PATIENTS AND METHODS: A series of 256 consecutive patients with histologically proven CIN1 recruited in a multicentre, observational, Italian study. Patients have been enrolled in a 24-weeks protocol of treatment and re-tested at the end of the study. Rates of regression have been recorded. RESULTS: Overall regression rate to a negative histology at the end of the 6 month follow up was 75.5%. CONCLUSIONS: Regression to normal histology was observed in a very high rate of cases in a very short period compared to the natural history of these lesions. CIN1 patients could benefit from bovine colostrum topical administration in terms of significantly shortening the regression time.

OBJECTIVE: This pilot study aimed to assess the efficacy and feasibility of fractional CO2 laser in the treatment of vulvovaginal atrophy (VVA) in postmenopausal women. METHODS: VVA symptoms were assessed before and after three applications of laser over 12 weeks in 50 women (age 59.6 ± 5.8 years) dissatisfied with previous local estrogen therapies. Subjective (visual analog scale) and objective (Vaginal Health Index Score, VHIS) measures were used during the study period to assess VVA. Quality of life was measured by using the SF-12. A subjective scale to evaluate the degree of pain related to the laser application and the degree of difficulty to perform the laser procedure was used. RESULTS: Fractional CO2 laser treatment was effective to improve VVA symptoms (vaginal dryness, vaginal burning, vaginal itching, dyspareunia, dysuria; p < 0.001) at 12-week follow-up, as well as the VHIS (13.1 ± 2.5 at baseline vs. 23.1 ± 1.9; p < 0.001). Both physical and mental scores of quality of life were significantly improved in comparison with baseline (p < 0.001). Satisfaction with the laser procedure was reported by 42 women (84%) and a minimal discomfort was experienced at the first laser application, mainly because of the insertion and the movements of the probe. Finally, the technique was very easy to perform in all women starting from the second application at week 4 and no adverse events were recorded during the study period. CONCLUSIONS: A 12-week treatment with the fractional CO2 laser was feasible and induced a significant improvement of VVA symptoms by ameliorating vaginal health in postmenopausal women. Further controlled studies should be performed to confirm the present data and to assess the long-term effects of the laser procedure on vaginal tissues.

Cervical tissue explants (CTEs) from 22 HIV-1 seronegative women were exposed to R5 HIV-1 ex vivo. Eight CTEs were productively infected in terms of HIV-1 p24Gag release in culture supernatants, whereas 14 were not. Nonetheless, both accumulation of HIV-1gag DNA and of p24Gag(+) CD4(+) T cells and macrophages occurred in both productive and, at lower levels, in nonproductive CTEs. Nonproductive CTEs differed from productive CTEs for higher secretion of C-C motif chemokine ligand 3 (CCL3) and CCL5. A post-hoc analysis revealed that all productive CTEs were established from women in their secretory phase of the menstrual cycle, whereas nonproductive CTEs were derived from women either in their secretory (28%) or proliferative (36%) menstrual cycle phases or with an atrophic endometrium (36%). Thus, our results support the epidemiological observation that sexual HIV-1 transmission from males to women as well as from women to men is more efficient during their secretory phase of the menstrual cycle.

The correlation between high-risk HPV-DNA viral load, expressed as relative light units (RLU) values obtained from the Hybrid Capture 2 (HC2) test, and the prevalence of CIN2/CIN3 was investigated and statistically analyzed in 614 ASC-US consecutive cases. Cases were categorized into three groups according to RLU values: "low-grade positivity", "intermediate positivity" and "high-grade positivity", and the prevalence of CIN2/CIN3 was evaluated in the single groups and compared among them. CIN/CIN3 rates demonstrated a significant (p < 0.001) increase with a direct correlation with increasing RLU values: 4.6% (RLU from 1.0 to 10.0), 9.1% (RLU from 11.0 to 100.0) and 32.2% (RLU > 100.0) respectively. The prevalence of CIN2/CIN3 between the group with RLU < 10.0 (4.6%) and the group with RLU > 10 (24.2%) showed statistical significance (p = 0.0002). Increasing hrHPV viral load significantly correlates with increasing prevalence of CIN2/CIN3 in ASC-US cases.

The large amount of literature published over the last two decades on human papillomavirus (HPV)-DNA testing has definitely demonstrated the association between high-risk viral genotypes (hrHPV) and cervical cancer. Moreover, hrHPV-DNA testing has shown excellent performance in several clinical applications, from screening settings to the follow-up of treated patients, compared to conventional cytology or colposcopy options. On the other hand, when a huge number of reports are published on the same subject in a relatively short period of time, with many variations in settings, study designs and applications, the result is often confusion and decreased comprehension by readers. In daily office practice, several different situations (in symptomatic or asymptomatic women) can be positively managed by the correct use of hrHPV-DNA testing. Validated hrHPV-DNA testing and, specifically, the HC2® assay, due to its excellent sensitivity and negative predictive value together with optimal reproducibility, currently represent a powerful tool in the clinician's hands to optimally manage several situations related to HPV infection and the potential development of cervical cancer.
RESUMEN
Human papillomavirus (HPV) testing is more sensitive and has higher negative predictive value (NPV) than the Pap test for the detection of cervical intraepithelial neoplasia (CIN) in patients with atypical squamous cells of undetermined significance (ASCUS) cytology, but has low specificity, leading to high referral rates to second-level triage. Our goal was to identify the prognostic significance of HPV viral load figures. We evaluated whether a correlation between viral load, expressed as relative light units/cutoff (RLU/CO), and the severity of cervical lesions existed in 614 ASCUS cases. Hybrid Capture 2 (HC2®) RLU/CO values, categorised into five classes, were correlated to clinical outcomes and statistically analysed. A significant correlation (p < 0.0001) was observed between increasing RLU values and the prevalence of high-grade CIN (CIN2/CIN3). The mean RLU values for negative, low-grade and high-grade lesions were 68.1, 172.5 and 1,020.0 RLU/CO, respectively (p < 0.0001). CIN2/CIN3 ranged from 4% for 0 < RLU/CO values ≤ 1, to 5% for 1 < RLU/CO values ≤ 10, to 9% for 10 < RLU/CO values ≤ 100, to 23% for 100 < RLU/CO values ≤ 1,000 and to 48% when RLU/CO values were >1,000 (p < 0.05). The HPV viral load in ASCUS cases significantly correlates with the severity of cervical cancer precursors. These data may have prognostic value, as they significantly correlate with the probability of a CIN2+ .

Genital human papillomavirus infection is one of the most common sexually transmitted diseases. Polyhexamethylene biguanide is a new agent, that has been demonstrated to have potent in vivo antiviral effects in animal and in human models. The present prospective, double-blind, randomized, placebo (vehicle-controlled) trial evaluated the efficacy and safety of daily patient-applied polyhexamethylene biguanide for up to 16-weeks for the treatment of external genital warts. Wart recurrence was investigated during a 12-week treatment-free follow-up period. In the intent-to-treat analysis, baseline warts cleared from 49 of 94 (52%) patients treated with polyhexamethylene biguanide cream versus and 3 of 95 (4%) placebo patients; the differences between the groups treated with placebo and polyhexamethylene biguanide were significant (P < 0.0001). For subjects who completed the follow-up period, recurrence rates after a complete response were 19% (9 of 48 patients) in the polyhexamethylene biguanide cream group, 17% cream group, and 0% (0 of 3) in the placebo group. There were no systemic reactions, although local skin reactions (generally of mild or moderate severity) were common in the polyhexamethylene biguanide cream group. Local reactions caused two patients to discontinue treatment. The most frequently reported local skin reactions were erythema, excoriation or flaking, and erosion. Patient-applied polyhexamethylene biguanide cream is effective for the treatment of external genital warts and has a favorable safety profile.

To determine the effect of highly active antiretroviral therapy (HAART) on high-risk human papillomavirus (HR-HPV) infections and related cervical lesions, the virologic and cytologic markers of HPV infection were prospectively studied in 163 human immunodeficiency virus (HIV)-infected women, including 27 untreated, 62 treated with reverse transcriptase inhibitors, and 74 treated with HAART. A high prevalence of both infections with HR-HPV types (68%) and squamous intraepithelial lesions (SILs; low grade, 20.2%; high grade, 6.2%) was observed. The risks of infection and disease were inversely correlated with CD4 cell counts (P=.015 and P=.022, respectively). During the observation period (mean, 15.4 months; range, 6-24 months), CD4 cell counts increased significantly only in subjects receiving HAART (P<.001). Persistence of HR-HPV infection and progression of SILs were comparable in the 3 groups. These results indicate that, even in the era of HAART, HIV-infected women should be monitored carefully for the emergence of high-grade SILs and cervical cancer.

OBJECTIVE: The role of HPV infection in cases of vulvar papillomatosis and vulvar vestibulitis syndrome is still unclear and data from the literature is controversial. In this study we intended to investigate the prevalence of viral infection, with a multidisciplinary approach, in cases with a co-existence of the two patterns. METHOD: Sixteen consecutive cases with diagnosis of vulvar vestibulitis syndrome and co-existence of vestibular papillomatosis were enrolled in the study and investigated by the means of vulvar cytology, vulvoscopy, histology, ViraPap and Polymerase Chain Reaction. RESULT: Cytology, vulvoscopy and histology did not demonstrate suitable accuracy for the diagnosis. Viral DNA identification revealed two (12.50%) positive cases using PCR and one (6.25%) positive case with ViraPap. CONCLUSION: The results of the present investigation indicate that even in cases of co-existing vulvar papillomatosis and severe vulvar vestibulitis syndrome, the prevalence of HPV infection is too low to be considered causal.

The purpose of this study was to investigate the presence of risk factors for node metastases and to estimate survival in patients with cervical cancer, stages IB and IIA. In a retrospective study of 103 patients with cervical cancer stages IB and IIA, all treated with radical hysterectomy and adjuvant radiotherapy, we estimated survival curves according to different prognostic parameters. Mean follow-up time was 97 months. A significant difference between clinical pre-operative assessment and histological determination of real extent of the disease was evidenced. Pelvic lymph node metastases (P = 0.0005) significantly correlated with survival. This study shows that only lymph node involvement is an independent prognostic factor. Stage acts through nodal status in its impact on survival. A surgical-pathological staging in early stage cervical cancers is found to be more appropriate to correctly estimate patients' survival and prognosis.

Given the frequency and persistence of human papillomavirus (HPV) infection and associated cytological alterations in HIV-1-positive women, the incidence of uterine cervix neoplasm is likely to increase along with patient survival. More appropriate screening programs, which, in addition to Pap smears (PS), also include tests to detect and type HPV, are needed for the early identification of precancerous cervical lesions. This prospective study involved 168 HIV-positive (group A) and 100 HIV-negative women (group B). Cervicovaginal samples were collected for a PS and HPV DNA search. The detected virus was typed as high-intermediate oncogenic risk HPV (HR-HPV) and low-risk HPV (LR-HPV) using hybrid capture (HC) (Murex-Digene) and in-house PCR tests. The HC-detected prevalence of HPV was 111/168 (66%:HR 75.6%) in group A and 15/100 (15%:HR 42.9%) in group B (P < 0.0001). Polymerase chain reaction (PCR) was positive in 91% and 48%, respectively. No significant difference was observed between drug addicts and heterosexual HIV-1-positive women (P = 0.09). HPV was detected in 94% of the 57 HIV-positive women with cytological alterations. HR-HPV was found in 41/49 women with low-grade and 7/8 with high-grade squamous intraepithelial lesions (LSIL and HSIL, respectively). In women with a negative PS, HPV was detected in 57/111 cases (HR 63%) of group A and in 13/98 of group B (6 cases of HR). Of the 54 group A women who underwent biopsy, histology revealed that 41 had LSIL (18 with negative PS, 19 with LSIL, and 4 with HSIL; HR-HPV in 73% and LR-HPV in 17%), nine had HSIL (5 LSIL and 4 HSIL on cytology; HR-HPV in 89% and LR-HPV in 11%), and four were negative (all cytology negative; 3 HR-HPV and 1 LR-HPV). HR-HPV was more frequent as immunodepression worsened. These results show that cytological evaluation alone underestimated histological alterations in 23/50 women (42.6%), whereas the combination of Pap smear and HPV detection reduced this underestimate to 5%.
