Age-related changes in the diagnostic assessment of women with severe cervical lesions.

OBJECTIVES: To evaluate the effect of age on the diagnostic assessment of women with severe cervical intraepithelial neoplasia (CIN). METHODS: This retrospective observational study included 338 consecutive women with a diagnosis of CIN3 on cone specimen. Patients were divided into three groups according to age: < 35 years (Group A), 35-49 years (Group B), and ≥ 50 years (Group C). Clinical and colposcopic variables were compared, and human papillomavirus (HPV) genotype distribution was measured. RESULTS: The most common HPV genotype was HPV-16 (63.65%), followed by HPV-33 (7%), HPV-18 (6.2%), and HPV-31 (5.4%). The rate of the following high-grade lesion predictors was lower in Group C than in Groups A and B: HPV-16 infections (55.9% vs. 75% vs. 70.9%, respectively, p = 0.022); high-grade colposcopic impression (29.4% vs. 51.8% vs. 51.7%, respectively, p < 0.0001); and high-grade cytological changes (30.9% vs. 56.2% vs. 45.4%, respectively, p = 0.025). An endocervical lesion location was more frequent in Group C than in Groups A and B (55.6% vs. 6.8% vs. 11.8%, respectively, p < 0.0001). CONCLUSION: Women aged 50 years and older with CIN3 showed a significant reduction of high-grade lesion predictors along with physiological confounding cervical changes (transformation zone type 3 and endocervical lesion location). The diagnostic work-up of cervical lesions in older women should provide their potential consideration as a special population.

Cervical pessary for preterm birth prevention after an episode of arrested preterm labor: a retrospective cohort study with targeted maximum likelihood estimation of the average treatment effect.

OBJECTIVE: To evaluate whether cervical pessary effectively reduces the preterm birth < 37 weeks rate in patients who have not delivered after an episode of arrested preterm labor. PATIENTS AND METHODS: Retrospective cohort study was conducted on singleton pregnant patients admitted to our institution between January 2016 and June 2021 for threatened preterm labor and who had a cervical length < 25 mm. Women in whom a cervical pessary was placed were considered as exposed, while women in whom expectant management was preferred were considered as unexposed. The primary outcome was the rate of preterm birth before 37 weeks. A targeted maximum likelihood estimation was used to estimate the average treatment effect of cervical pessary by adjusting for a-priori-defined confounders. RESULTS: A cervical pessary was placed in 152 (36.6%) patients (exposed), while the remaining 263 (63.4%) were managed expectantly (unexposed). The adjusted average treatment effect was -14% (-18 to -11%), -17% (-20 to -13%), and -16% (-20 to -12%) for preterm birth < 37 weeks, < 34 weeks, and < 32 weeks, respectively. The average treatment effect for adverse neonatal outcomes was -7% (-8 to -5%). No difference in gestational weeks at delivery between exposed and unexposed emerged when gestational age at first admission was > 30.1 gestational weeks. CONCLUSIONS: The positioning of a cervical pessary placement may be evaluated to reduce the risk of a subsequent preterm birth after an episode of arrested preterm labor in pregnant patients with onset of symptoms before 30 gestational weeks.

Atrophic endometrium in postmenopausal women referred to diagnostic hysteroscopy: a study to avoid unnecessary examinations.

OBJECTIVE: Any diagnostic workup should be based on appropriateness criteria. Diagnostic hysteroscopy is a procedure widely used in endometrial pathology. Its high outpatient feasibility frequently leads to misuse. However, it can cause discomfort and, albeit rarely, complications. The present study aimed to provide an estimate of unnecessary examinations based on variables associated with atrophic endometrium in postmenopausal women referred to diagnostic hysteroscopy. PATIENTS AND METHODS: One-hundred and sixty-six postmenopausal women undergoing hysteroscopy were retrospectively analyzed. All included women had a final histological reference standard. The sample was divided into women with atrophic endometrium vs. women with endocavitary lesions (benign/premalignant/malignant). Univariate and multivariate analysis was performed to assess those patient characteristics associated with atrophic endometrium. Furthermore, based on the likelihood ratios, a post-test probability analysis was performed to provide an estimate of atrophy according to the presence of specific variables. RESULTS: Sixty-one postmenopausal women (36.7%) undergoing diagnostic hysteroscopy showed atrophic endometrium at final histology. Multivariate analysis showed that the independent variables associated with atrophy were the absence of abnormal uterine bleeding [Odds Ratio (OR)=6.43, Confidence Intervals (CI) 2.087 to 19.822], and endometrial thickness (criterion < 7 mm) (OR=0.417, CI 0.300 to 0.578). In women showing both variables associated with negative endometrial outcome, post-test probability analysis resulted in an atrophic endometrium rate of 89.13%, from a pre-test probability of 36.7%. CONCLUSIONS: About 90% of asymptomatic postmenopausal women with endometrial thickness <7 mm resulted in an atrophic endometrium at hysteroscopy. Every gynecologist should know and consider these data before referring such women to further examinations. In these cases, diagnostic hysteroscopy is not cost-effective leading to a high number of false positives.

[Preoperative platelet count as index of the grading in endometrial carcinoma]. / Conta piastrinica preoperatoria come indice del grading nel carcinoma endometriale.

AIM: To investigate a possible relationship between preoperative platelet count and following clinicopathological variables of the endometrial carcinoma: age, stage, histological type, histological grading (G), myometrial invasion, lymphovascular space involvement, cervical involvement, lymph node metastasis. In particular the existence of a possible relationship between elevated preoperative platelet count (=or>300 000 microL) and negative prognostic factors. METHODS: The authors analyzed retrospectively 120 patients with endometrial carcinoma underwent to surgery as the initial treatment. All the patients were subjected to radical surgical procedure: peritoneal cytology, total abdominal hysterectomy, bilateral salpingo-oophorectomy, systematic pelvic lymphadenectomy and omentectomy. Blood platelet count was taken from the patients three days prior to the surgery. RESULTS: The patients with platelet count<300000/microL whom they had a G1, G2, G3 they were respectively the 23.1%, 44.2% and 32.7% versus the 0%, 12.5% and 87.5%, respectively for G1, G2, G3, of the patients with platelet count>300000/microL (P=0.024). Only considering the patients to the stage I of the Federazione Internazionale dei Ginecologi ed Ostetrici (FIGO). The patients with platelet count<300000/microL whom they had a G1, G2, G3 they were respectively the 27.3%, 43.2% and 29.5% versus the 0%, 0% and 100%, respectively for G1, G2, G3, of the patients with platelet count=or>300000/microL (P=0.008). There were no differences respect to age, stage, histological type, myometrial invasion, lymphovascular space involvement and cervical involvement. CONCLUSION: Elevated preoperative platelet count, in the patients with endometrial carcinoma, may reflect poor prognostic factor such as higher histological grade. This study allowed to observe: a significant correlation between elevated preoperative platelet count (=or>300000/microL) and tumoral grading (G3) of general population submitted to study; for the patients to the stage I FIGO a more significant correlation between elevated preoperative platelet count (=or>300000/microL) and tumoral grading: the 100% of the patients with platelet count=or>300 000/microL had a histological grading G3.

Diagnostic accuracy of endometrial thickness for the detection of intra-uterine pathologies and appropriateness of performed hysteroscopies among asymptomatic postmenopausal women.

OBJECTIVE: To measure the diagnostic accuracy of endometrial thickness for the detection of intra-uterine pathologies among asymptomatic postmenopausal women, and to test the diagnostic accuracy and appropriateness of performed hysteroscopies. STUDY DESIGN: Prospective study of 268 asymptomatic postmenopausal women with endometrial thickness ≥4 mm referred to diagnostic hysteroscopy. The diagnostic accuracy of various endometrial thickness cut-off values was tested. Histological and hysteroscopic results were compared to measure the diagnostic accuracy of outpatient hysteroscopies. RESULTS: No endometrial thickness cut-off values had optimal diagnostic accuracy [positive likelihood ratio (LR+) >10 and negative likelihood ratio (LR-) <0.1]. The best endometrial thickness cut-off value for the detection of all intra-uterine pathologies was ≥8 mm (LR+ 10.05 and LR- 0.22). An endometrial thickness cut-off value ≥10 mm did not miss any cases of endometrial cancer. The success rate of diagnostic hysteroscopy was 89%, but 97% of these revealed a benign intra-uterine pathology. The diagnostic accuracy of hysteroscopy was optimal for all intra-uterine pathologies, except endometrial hyperplasia (LR- 0.52). CONCLUSION: Using an endometrial thickness cut-off value ≥4 mm, only 3% of performed hysteroscopies were useful for the detection of pre-malignant or malignant lesions. Despite the finding that endometrial thickness did not show optimal diagnostic accuracy, using the best cut-off value (≥8 mm) may be helpful to decrease the number of false-positive results. No cases of endometrial cancer were diagnosed in asymptomatic postmenopausal women with endometrial thickness <10mm.

[Prophylaxis of superficial tumors of the bladder with interferon alfa-2B]. / Profilassi dei tumori superficiali della vescica con interferone alpha 2b.

The AA. report the results obtained on patients suffering from surface bladder cancer [Ta-T1 (G1-G2)] treated with alpha 2b interferon with the aim to elongate the relapse period. The results turned out to be very satisfactory as concerns the tolerability of the drug as well as the actual improvement in relapse onset. Moreover, the AA. could notice the grading steadiness or decrease, as to neglistic relapses.

Different concentrations of interleukins in the peritoneal fluid of women with endometriosis: relationships with lymphocyte subsets.

The present study explored the possible relationships between immune cell subsets and interleukin (IL)-12 or IL-13 levels in the peritoneal fluid of patients with and without endometriosis. Peritoneal fluid samples were obtained from 80 women while they were undergoing laparoscopy for pain, infertility, tubal ligation or re-anastomosis. The American Fertility Society scoring system was used to determine the extension of endometriosis. The peritoneal fluid mononuclear cells were analyzed for immunophenotyping using cytometry, whereas peritoneal fluid concentrations of interleukins were measured using two ultrasensitive commercially available enzyme-linked imnunosorbent assay kits. Significantly higher peritoneal fluid IL-12 levels were found in women with moderate or severe endometriosis (stages III and IV) than in healthy controls (p < 0.01). Conversely, subjects with endometriosis showed remarkably lower peritoneal fluid IL-13 concentrations than controls, independent of the severity of the disease (p < 0.05). Considering immune system effectors, patients with endometriosis presented a significantly higher peritoneal fluid CD8+/CD4+ ratio when compared with healthy controls. Moreover, the number of peritoneal fluid CD8+ and CD4+ activated T cells was significantly lower in the former than in the latter group, independent of the endometriosis stage. Connections were observed between peritoneal fluid interleukins and peritoneal fluid T cells: both patients with endometriosis and controls presented an inverse correlation between peritoneal fluid activated T cells and IL-13 levels, and a direct correlation between peritoneal fluid T cells and IL-12 concentrations. These data seem to suggest that a reciprocal modulation exists between peritoneal fluid cytokines and T lymphocyte subsets in patients with endometriosis.
