RESUMO

OBJECTIVE: The COVID-19 pandemic had significant effects on healthcare systems worldwide, including the disruption of routine screening programs for cervical cancer. This study aimed to compare the incidence of cervical intra-epithelial neoplasia (CIN)2 and CIN3 lesions, adenocarcinoma, and squamous carcinoma of the cervix before and after the COVID-19 pandemic. METHODS: A retrospective analysis was performed using archive data from the Policlinico di Bari, Unit of Gynecology and Obstetrics. The study included patients who tested positive for high-risk human papillomavirus (HPV) at the level I screening test (HPV test) and were subsequently referred to level II screening, which involves the Papanicolaou (Pap) test and colposcopic examination. We excluded individuals who did not comply with the recommended follow-up, patients with low-risk HPV infection, those with autoimmune diseases, oncologic diseases, or those undergoing immunosuppressive therapies. The time period spanned from January 2020 to December 2022. The incidence of CIN2/CIN3 lesions, adenocarcinoma, and squamous carcinoma of the cervix was compared between the pre-screening period (2017-2019) and the post-screening period (2020-2022). RESULTS: The study comprised a cohort of 1558 consecutive European sexually active women with a median age of 34 years (range 25-65) who underwent colposcopic evaluation of the uterine cervix as a level II screening program. The comparison between the pre-screening and post-screening periods showed an increase in the incidence of CIN2/CIN3 lesions, rising from 23.9 to 63.3 per 100 000 (HR 2.62, 95% CI 1.64 to 4.20; p<0.001). Additionally, although there was an absolute increase in the incidence of cervical carcinoma and adenocarcinoma, the comparison did not reach statistical significance (squamous carcinoma: 2017-2019, 2.5 per 100 000; 2020-2022 3.4 per 100 000, p=0.72; adenocarcinoma: 2017-2019, 3.5 per 100 000; 2020-2022 7.6 per 100 000, p=0.24). CONCLUSION: This study showed a significant increase in the incidence rate of CIN2/CIN3 lesions after the COVID-19 pandemic. Our findings may be attributed to the temporary suspension of follow-up programs during the pandemic, although the study does not rule out direct effects of SARS-CoV-2 on the risk of pre-neoplastic and neoplastic conditions of the cervix.

RESUMO

In eutocic labor, the autonomic nervous system is dominated by the parasympathetic system, which ensures optimal blood flow to the uterus and placenta. This study is focused on the detection of the quantitative presence of catecholamine (C) neurofibers in the internal uterine orifice (IUO) and in the lower uterine segment (LUS) of the pregnant uterus, which could play a role in labor and delivery. A total of 102 women were enrolled before their submission to a scheduled cesarean section (CS); patients showed a singleton fetus in a cephalic presentation outside labor. During CS, surgeons sampled two serial consecutive full-thickness sections 5 mm in depth (including the myometrial layer) on the LUS and two randomly selected samples of 5 mm depth from the IUO of the cervix. All histological samples were studied to quantify the distribution of A nerve fibers. The authors demonstrated a significant and notably higher concentration of A fibers in the IUO (46 ± 4.8) than in the LUS (21 ± 2.6), showing that the pregnant cervix has a greater concentration of A neurofibers than the at-term LUS. Pregnant women's mechanosensitive pacemakers can operate normally when the body is in a physiological state, which permits normal uterine contractions and eutocic delivery. The increased frequency of C neurofibers in the cervix may influence the smooth muscle cell bundles' activation, which could cause an aberrant mechano-sensitive pacemaker activation-deactivation cycle. Stressful circumstances (anxiety, tension, fetal head position) cause the sympathetic nervous system to become more active, working through these nerve fibers in the gravid cervix. They might interfere with the mechano-sensitive pacemakers, slowing down the uterine contractions and cervix ripening, which could result in dystocic labor.

RESUMO

BACKGROUND: Clinical evidence suggests that pregnant women are more vulnerable to COVID-19, since they are at increased risk for disease progression and for obstetric complications, such as premature labor, miscarriage, preeclampsia, cesarean delivery, fetal growth restriction and perinatal death. Despite this evidence, pregnant women are often excluded from clinical trials, resulting in limited knowledge on COVID-19 management. The aim of this systematic review and meta-analysis is to provide better evidence on the efficacy and safety of available COVID-19 treatment in pregnant women. METHODS: Four authors searched major electronic databases from inception until 1 st November-2022 for controlled trials/observational studies, investigating outcomes after the administration of anti-SARS-CoV-2 treatments in pregnant women affected by COVID-19. The analyses investigated the cumulative incidence of delivery and maternal outcomes in pregnant women, comparing those taking active medication vs standard care. Risk ratios (RRs) with 95% confidence intervals were calculated. Statistical significance was assessed using the random effects model and inverse-variance method. This systematic review and meta-analysis was conducted in accordance with the updated 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The protocol has been registered in Prospero (number registration: CRD42023397445). RESULTS: From initially 937 non duplicate records, we assessed the full texts of 40 articles, finally including ten studies. In six studies, including 1627 patients, the use of casirivimab/imdevimab (CAS/IMD), remdesivir, and IFN-alpha 2b significantly decreased the need of cesarean section ((RR = 0.665; 95%CI: 0.491-0.899; p = 0.008; I 2 = 19.5%;) (Table 1, (Fig. 1). Treatments did not decrease the risk of preterm delivery, admission to neonatal ICU, or stillbirth/perinatal loss (p-values > 0.50 for all these outcomes) and did not prevent the progression of disease towards severe degrees (k = 8; 2,374 pregnant women; RR = 0.778; 95%CI: 0.550-1.099; p = 0.15; I 2 = 0%). Moreover, the use of medications during pregnancy did not modify the incidence of maternal death in two studies (Table 2). CONCLUSIONS: To our analysis, CAS/IMD, remdesivir, and IFN alpha 2b reduced the number of cesarean sections but demonstrated no effect on disease progression and other obstetric and COVID-19 related outcomes. The inability to evaluate the influence of viral load on illness development in pregnant women was attributed to lack of data. In our systematic review, no major side effects were reported. Though, it is essential for the medical community to focus more on clinical trials and less on episodic case reports and case series, with standardization of fetal and maternal outcomes.

RESUMO

OBJECTIVE: To summarize evidence from randomized controlled trials (RCTs) on the effectiveness of virtual reality technology (VRT), as used by patients, for reducing pain during outpatient hysteroscopy. DATA SOURCES: Electronic databases and clinical registers were searched until June 21, 2023. The review protocol was registered in PROSPERO before the data extraction (CRD42023434340). METHODS OF STUDY SELECTION: We included RCTs of patients receiving VRT compared with controls receiving routine care during outpatient hysteroscopy. TABULATION, INTEGRATION, AND RESULTS: The primary outcome was average pain during hysteroscopy. Pooled results were expressed as mean differences (MDs) with 95% confidence interval (CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. Five RCTs were included (435 participants). The comparison between the intervention and control groups showed a borderline difference in perceived pain during hysteroscopy (MD -0.88, 95% CI -1.77 to 0.01). Subgroup analysis based on the type of VRT (active or passive) indicated that active VRT potentially reduced the perception of pain (MD -1.42, 95% CI -2.21 to -0.62), whereas passive VRT had no effect (MD -0.06, 95% CI -1.15 to 1.03). CONCLUSION: Patients' use of active VRT may be associated with a reduction in pain during outpatient hysteroscopy (evidence Grading of Recommendations Assessment, Development, and Evaluation 2/4). Future research should focus on conducting methodologically robust studies with larger sample sizes and more homogeneous populations.

RESUMO

The investigation studied the enkephalinergic neuro fibers (En) contained in the Lower Uterine Segment (LUS) during the prolonged dystocic labor (PDL) with Labor Neuraxial Analgesia (LNA). PDL is generally caused by fetal head malpositions in the Occiput Posterior Position (OPP), Persistent Occiput Posterior Position (POPP), in a transverse position (OTP), and asynclitism (A), and it is detected by Intrapartum Ultrasonography (IU). The En were detected in the LUS samples picked up during cesarean section (CS) of 38 patients undergoing urgent CS in PDL, compared to 37 patients submitted to elective CS. Results were statistically evaluated to understand the differences in En morphological analysis by scanning electron microscopy (SEM) and by fluorescence microscopy (FM). The LUS samples analysis showed an important reduction in En in LUS of CS for the PDL group, in comparison with the elective CS group. The LUS overdistension, by fetal head malpositions (OPP, OTP, A) and malrotations, lead to dystocia, modification of vascularization, and En reduction. The En reduction in PDL suggests that drugs used during the LNA, usually local anesthetics and opioids, cannot control the "dystocic pain", that differs from normal labor pain. The IU administration in labor and the consequent diagnosis of dystocia suggest stopping the numerous and ineffective top-up drug administration during LNA, and to shift the labor to operative vaginal delivery or CS.

RESUMO

All cancers develop as a result of mutations in genes. DNA damage induces genomic instability and subsequently increases susceptibility to tumorigenesis. Women who carry mutations of BRCA 1 and BRCA2 genes have an augmented risk of breast and ovarian cancer and a markedly augmented probability of dying because of cancer compared to the general population. As a result, international guidelines recommend that all BRCA1\2 mutation carriers be offered risk-reducing bilateral salpingo-oophorectomy at an early age to reduce the risk of cancer and decrease the mortality rate of this high-risk population. NCCN guidelines recommend risk-reducing bilateral salpingo-oophorectomy in pre-menopausal women, between 35-40 years in BRCA1 mutation carriers and between 40-45 years in BRCA2 mutation carriers. Unfortunately, the well-documented reduction of cancer risk is counterbalanced by early sterility and premature ovarian failure with an early onset of secondary menopausal syndromes such as neuromotor, cardiovascular, cognitive and urogenital deficiency. Hormonal replacement therapy significantly compensates for hormonal deprivation and counteracts menopausal syndrome morbidity and mortality; however, some data suggest a possible correlation between hormonal medications and cancer risk, especially in BRCA1\2 carriers who undergo long-term regimens. Conversely, short-term treatment before the age of natural menopause does not appear to increase the cancer risk in BRCA1 mutation carriers without a personal history of breast cancer after prophylactic surgery. Few data are available on BRCA2 mutation carriers and more well-designed studies are needed. In conclusion, clinicians should propose short-term hormone replacement therapy to BRCA 1 carriers to counteract hormonal deprivation; personalized counselling should be offered to BRCA2 mutation carriers for a balance between the risks and benefits of the treatment.

RESUMO

One emerging problem for onco-gynecologists is the incidence of premenopausal patients under 40 years of age diagnosed with stage I Endometrial Cancer (EC) who want to preserve their fertility. Our review aims to define a primary risk assessment that can help fertility experts and onco-gynecologists tailor personalized treatment and fertility-preserving strategies for fertile patients wishing to have children. We confirm that risk factors such as myometrial invasion and The International Federation of Gynecology and Obstetrics (FIGO) staging should be integrated into the novel molecular classification provided by The Cancer Genome Atlas (TCGA). We also corroborate the influence of classical risk factors such as obesity, Polycystic ovarian syndrome (PCOS), and diabetes mellitus to assess fertility outcomes. The fertility preservation options are inadequately discussed with women with a diagnosis of gynecological cancer. A multidisciplinary team of gynecologists, oncologists, and fertility specialists could increase patient satisfaction and improve fertility outcomes. The incidence and death rates of endometrial cancer are rising globally. International guidelines recommend radical hysterectomy and bilateral salpingo-oophorectomy as the standard of care for this cancer; however, fertility-sparing alternatives should be tailored to motivated women of reproductive age, establishing an appropriate cost-benefit balance between childbearing desire and cancer risk. New molecular classifications such as that of TCGA provide a robust supplementary risk assessment tool that can tailor the treatment options to the patient's needs, curtail over- and under-treatment, and contribute to the spread of fertility-preserving strategies.

RESUMO

OBJECTIVE: Proposing hysteroscopic morcellation (HM) as a surgical-therapeutic approach in the treatment of retained products of conception (RPOC) to prevent intrauterine adhesions (IUAs). DESIGN: Prospective analysis. SETTING: A teaching and university hospital. PATIENTS: Women with RPOC. INTERVENTIONS: Office -HM with 'Truclear 5 C'. MATERIAL AND METHODS: Twenty-two consecutive patients presenting with trophoblastic residue retention after miscarriage and interruption of pregnancy or placenta remnants after cesarean section or delivery were enrolled. These women underwent office-HM with 'Truclear 5 C'. Primary outcomes were median time and rate of hospitalization. The quality of the specimen was also analyzed. A hysteroscopic second look for IUAs was performed. RESULTS: Mean procedure time was six minutes (SD ± 5). Tissue samples had a mean collection size 2.5 cm3+0.9. 38% of the samples had spotting or abnormal vaginal discharge. Dilatation of the cervical canal was not performed in any case. Second-look hysteroscopy did not show any de novo IUAs in any of the enrolled patients. CONCLUSIONS: In the hysteroscopic treatment of RPOC, HM is a valid choice in an office setting without the use of cervical dilatation. Removal of RPOC was uneventful in all cases, simple and carried out faster without any adverse outcomes.

RESUMO

The outcome of patients with Hodgkin lymphoma (HL) has improved significantly in recent years, and now attention is increasingly being focused on the well-being of these young patients. This study aimed to analyse the influence of HL and its treatment on the spermatogenic status of 46 male HL patients with available spermiograms, treated between 2008 and 2016. Analysing prognostic factors at diagnosis, we found that the number of spermatozoa was reduced in stage III-IV; motility and vitality were reduced in stage III-IV and in the presence of B symptoms; and abnormal forms were increased in patients with elevated erythrocyte sedimentation rate (ESR) and low albumin. Furthermore, we found that haematopoietic stem cell transplantation (HSCT) was associated with a severe impairment of fertility in terms of sperm motility. In HL-treated patients who did not undergo HSCT we found a statistically significantly improved fertility in terms of motility. In this study, we found that HSCT induced infertility in the majority of male patients with HL, but that first-line treatment could improve the impaired fertility status caused by disease. Further studies are needed in larger case series to investigate risk factors for impaired fertility at HL diagnosis and after treatment.

RESUMO

BACKGROUND: Thrombotic microangiopathy has been invoked as one of the most important mechanisms of damage in COVID-19 patients. Protease ADAMTS13 is a marker of microangiopathy responsible for controlling von Willebrand multimers size. Von Willebrand factor/ADAMTS13 ratio has been found impaired in COVID-19 patients outside pregnancy. METHODS: We prospectively investigated 90 pregnant women admitted to two tertiary academic hospitals in Italy with a laboratory-confirmed diagnosis of SARS-CoV-2 infection. Demographic, clinical information and routine laboratory data were collected at the hospital admission and until discharge. We investigated whether vonWillebrand /ADAMTS13 axis imbalance is a predictor of adverse outcomes. Logistic regression analysis, which controlled for potential confounders, was performed to evaluate the association between laboratory parameters and clinical outcomes. RESULTS: Most women (55.6%) were parae, with median gestational age at admission of 39 weeks. At hospital admission, 63.3% were asymptomatic for COVID-19 and 24.4% showed more than one sign or symptom of infection. Nulliparae with group O showed Willebrand / ADA MTS-13 ratios significantly lower than non-O, whereas in multiparae this difference was not observed. Logistic regression showed that ratio von Willebrand to ADAMTS13 was significantly and independently associated with preterm delivery (OR 1.9, 95%CI 1.1-3.5). CONCLUSION: This study shows an imbalance of vonWillebrand /ADAMTS13 axis in pregnant women with COVID-19, leading to a significantly higher and independent risk of preterm delivery. Monitoring these biomarkers might support decision making process to manage and follow-up pregnancies in this setting.

RESUMO

PURPOSE: The current gold standard for chronic endometritis (CE) diagnosis is immunohistochemistry (IHC) for CD-138. However, IHC for CD-138 is not exempt from diagnostic limitations. The aim of our study was to evaluate the reliability and accuracy of MUM-1 IHC, as compared with CD-138. METHODS: This is a multi-centre, retrospective, observational study, which included three tertiary hysteroscopic centres in university teaching hospitals. One hundred ninety-three consecutive women of reproductive age were referred to our hysteroscopy services due to infertility, recurrent miscarriage, abnormal uterine bleeding, endometrial polyps or myomas. All women underwent hysteroscopy plus endometrial biopsy. Endometrial samples were analysed through histology, CD138 and MUM-1 IHC. The primary outcome was to evaluate the diagnostic accuracy of MUM-1 IHC for CE, as compared with CD-138 IHC. RESULTS: Sensitivity and specificity of CD-138 and MUM-1 IHC were respectively 89.13%, 79.59% versus 93.48% and 85.03%. The overall diagnostic accuracy of MUM-1 and CD-138 IHC were similar (AUC = 0.893 vs AUC = 0.844). The intercorrelation coefficient for single measurements was high between the two techniques (ICC = 0.831, 0.761-0.881 95%CI). However, among CE positive women, MUM-1 allowed the identification of higher number of plasma cells/hpf than CD-138 (6.50 [SD 4.80] vs 5.05 [SD 3.37]; p = 0.017). Additionally, MUM-1 showed a higher inter-observer agreement as compared to CD-138. CONCLUSION: IHC for MUM-1 and CD-138 showed a similar accuracy for detecting endometrial stromal plasma cells. Notably, MUM-1 showed higher reliability in the paired comparison of the individual samples than CD-138. Thus, MUM-1 may represent a novel, promising add-on technique for the diagnosis of CE.

RESUMO

In a growing number of social and clinical scenarios, machine learning (ML) is emerging as a promising tool for implementing complex multi-parametric decision-making algorithms. Regarding ovarian cancer (OC), despite the standardization of features that can support the discrimination of ovarian masses into benign and malignant, there is a lack of accurate predictive modeling based on ultrasound (US) examination for progression-free survival (PFS). This retrospective observational study analyzed patients with epithelial ovarian cancer (EOC) who were followed in a tertiary center from 2018 to 2019. Demographic features, clinical characteristics, information about the surgery and post-surgery histopathology were collected. Additionally, we recorded data about US examinations according to the International Ovarian Tumor Analysis (IOTA) classification. Our study aimed to realize a tool to predict 12 month PFS in patients with OC based on a ML algorithm applied to gynecological ultrasound assessment. Proper feature selection was used to determine an attribute core set. Three different machine learning algorithms, namely Logistic Regression (LR), Random Forest (RFF), and K-nearest neighbors (KNN), were then trained and validated with five-fold cross-validation to predict 12 month PFS. Our analysis included n. 64 patients and 12 month PFS was achieved by 46/64 patients (71.9%). The attribute core set used to train machine learning algorithms included age, menopause, CA-125 value, histotype, FIGO stage and US characteristics, such as major lesion diameter, side, echogenicity, color score, major solid component diameter, presence of carcinosis. RFF showed the best performance (accuracy 93.7%, precision 90%, recall 90%, area under receiver operating characteristic curve (AUROC) 0.92). We developed an accurate ML model to predict 12 month PFS.

RESUMO

Authors investigated the catecholaminergic neurotransmitters (chNs) quantitative modifications in pregnant uterine Lower Uterine Segment (LUS) during prolonged labor (PL) with the fetus in an occiput-posterior position (OPP), in occiput transverse position (OTP) and in fetal head asynclitism, all diagnosed by Intrapartum Ultrasonography (IU). The chNs neurotransmitters, particularly adrenaline (or epinephrine-A) and noradrenaline (or norepinephrine-N), were evaluated in LUS fragments sampled during CS of 34 patients undergoing urgent cesarean section (CS) in PL, compared to chNs fibers in the LUS of 36 women submitted to elective CS. All results were statistically analyzed to understand the differences in neurotransmitters morphological analysis by scanning electronic microscopy examination (SEM). The LUS fragments analysis revealed a reduction of A and N fibers in LUS during PL, compared with the expression of A and N fibers in LUS during elective CS. The PL for OPP, the OTP and asynclitism, all positions causing dystocia in labor lead to a reduction in neurotransmitters in LUS, with a uterine vascularization modification and a reduction in the contractility of smooth uterine cells. The A and N neurotransmitters reduction observed in PL negatively interferes with uterine contraction during labor.

RESUMO

Turner syndrome (gonadal dysgenesis with short stature and sterility) is characterized by chromosomal karyotype 45,X in 50% of cases or by mosaicism (45,X/46,XX and 45,X/46,XY) in 30-40% or X structural defects (deletions, long arm isochromosome, ring chromosome). When mosaic Turner syndrome (TS) occurs with a Y chromosome, there may be ambiguous genitalia. Duchenne muscular dystrophy (DMD) is an inherited neuromuscular disease with an X-Linked recessive pattern of inheritance that predominantly affects males, while females are usually asymptomatic. DMD has also been observed in groups of females affected by TS, not homozygous for the mutation. Here, we report a case of an Indian neonate born with ambiguous genitalia diagnosed prenatally by ultrasound who had a karyotype of 45,X/46,XY and who also had Duchenne muscular dystrophy caused by a de novo mutation in the DMD gene. Physical examination was normal without the typical dysmorphic features of TS with the exception of the genitourinary system showing ambiguous genitalia. Gender was assigned as female. At the age of three years, she had increasing difficulty walking, running, jumping and climbing stairs, proximal upper and lower extremity muscle weakness and a positive Gowers' sign. In addition, the serum creatine kinase (CK) value was over 30X the upper limit of normal. This study shows that DMD can occur in females with TS having 45,X/46,XY mosaicism and that this coexistence should be considered in women affected by TS who start to develop potential typical symptoms such as motor or developmental delay.

RESUMO

OBJECTIVE: Limited data are available on the frequency and time trends of pregnancy-associated cancers, particularly from Southern European countries. The aim of this study was to analyze the frequency and time trends of pregnancy-associated cancer in Italy. METHODS: This was a population-based linkage study using the regional hospital discharge forms database of four Italian regions with more than 17 million inhabitants. All resident women with a hospital discharge form reporting a birth or abortion in the time period under consideration were identified. The time period of the study was 2003-2015 for the Piemonte and Puglia region, 2006-2015 for the Tuscany region, and 2005-2015 for the Veneto region. Risk of developing a pregnancy-associated cancer was calculated as the ratio of the number of pregnancy-related cancers to the total number of pregnancies. RESULTS: A total of 2 297 648 pregnancies were identified. Overall, the pregnancy-associated cancer frequency was 134.8 per 100 000 pregnancies: the frequency ranged from 127.1 in Puglia to 157.3 in Tuscany. The frequency for 100 000 pregnancies was 66.4 in women aged <30 years; the risk increased with age, with a frequency of 275.6 among women aged 40+ years. Approximately two-thirds of cancers were associated with pregnancies resulting in a delivery and one-third with pregnancies resulting in a termination of pregnancy or spontaneous pregnancy loss. No clear trend emerged in the risk of pregnancy-associated cancer per 100 000 pregnancies and calendar year. CONCLUSION: No clear time trend was observed in the frequency of pregnancy-associated cancers in Italy during the last 10 years, the rates being 104, 164, and 130 per 100 000 pregnancies, respectively, in 2003, 2010, and 2015.

RESUMO

To describe a rare case of a singleton 8-week cornual pregnancy (CP), treated by laparoscopic incision of the uterine wall, the ectopic pregnancy was removed and the uterine site was sutured with interrupted sutures. A 21-year-old woman was admitted for suspected singleton CP at week 8. Clinical examination, b-hCG increase, and transvaginal ultrasonography (TU) were used to monitor the suspected diagnosis of an ectopic pregnancy. Following failure of methotrexate administration, surgeons performed a laparoscopy. The CP removal was performed by laparoscopic incision, enucleating the corneal mass and suturing the uterine site of the ectopic pregnancy with interrupted sutures. Intraoperative and postoperative complications and uterine integrity preservation were studied. Postoperative recovery period was normal, without intraprocedural or postprocedural complications.Uterine integrity was preserved. No further therapeutic interventions were needed in follow-up. This study confirmed the feasibility, safety and efficacy of performing a safe, minimally invasive, laparoscopic treatment of an early unruptured CP, without intraoperative and postoperative complications, with a normal postoperative recovery period and preservation of uterine integrity.

RESUMO

Granulosa cells (GC) tumors are rare tumors which account for approximately 2-3% of all ovarian malignancies with a favorable prognosis. We report a case of a 54-year-old postmenopausal woman who developed an ovarian GC tumor in the pelvic anterior preperitoneal space 20 years after laparotomic salpingo-oophorectomy due to small part of the cyst could drop or remain entrapped into the abdominal wound during the closure of laparotomy 20 years before. Then, the patient underwent a second laparoscopic procedure with peritoneal washing, a type A radical hysterectomy, omentectomy, appendectomy, and pelvic and para-aortic lymphadenectomy. This rare case of ovarian GC tumor developing in the site of previous laparotomy demonstrates the importance of a correct and clean surgical procedure to avoid the risk of leaving even small portions of the cyst exposing the patients to either the risk of malignancy or additional surgical procedures.Precis: This rare case of ovarian granulosa cells tumor developed from residual ovarian tissue intrapped into the abdominal wound 20 years after laparotomic ovariectomy.

RESUMO

STUDY OBJECTIVE: To evaluate the histology of the uterine septum after its complete hysteroscopic excision. DESIGN: Case series. SETTING: Second Gynecological and Obstetric Unit and Pathological Anatomy Department of the University of Bari, Italy. PATIENTS: Thirty-five patients aged between 25 and 41 years who were diagnosed with uterine septum by 3-dimensional ultrasound per the European Society for Human Reproduction and Embryology/European Society of Gastrointestinal Endoscopy 2013/Salim 2003 criteria. In addition, office hysteroscopy was performed to define the anatomy of the uterine cavity and to exclude the presence of other endometrial pathologic conditions. INTERVENTIONS: Operative hysteroscopic septum resection was performed. The septum was initially incised with an "L-shape" bipolar electrode with a 5-mm bipolar mini-resectoscope (KARL STORZ SE & Co. KG, Tuttlingen, Germany). Then, using the bipolar loop, 2 triangles of the septum were excised in parallel, obtaining uninterrupted entire septum-long strips from the fundus to the apex of the septum. These strips were immediately removed from the uterus and reassembled in vitro to reconstruct a macroscopic, 3-dimensional structure of the septum for complete morphologic and histologic evaluations. MEASUREMENTS AND MAIN RESULTS: Patients presented with an average body mass index of 24.8 kg/m2and were all nulliparous. Histologic evaluation of the uterine septa showed a different conformation of the muscle bundles along the septum. Muscle cells in the apex and edges of the septum were arranged in nodules circumscribed by a thin area of collagen fibers. Medium-sized vessels were distributed in the collagen fibers around the muscle cells. Only few capillary vessels were present in the muscle nodules. This pattern was very similar to the cell arrangement in leiomyomas. In the core of the septa, near the base, the muscle bundles showed a linear course with concurrent collagen fibers and vessels. All the aforementioned characteristics were consistently present in every patient. On high-power histologic fields (200×), the muscle portion accounted for 48.3% ± 1.8% (mean, 6%) area in the apex and borders to 48.5% ± 1.3% (mean, 6%) area in the core. Collagen fibers accounted for 27.1% ± 1.1% (mean, 4%) area in the apex and borders to 26.7% ± 1.3% (mean 5%) area in the core. CONCLUSION: By removing the septum as a whole structure, this study allowed us to redefine the concept of the septum as a complex structure according to the islands of muscle fibers irregularly arranged in vertex, in a context of collagen tissue and similar to the structure of myomas. It appears to deeply involve the anterior and posterior uterine walls, resembling a "reverse letter H."

RESUMO

Herlyn-Werner-Wunderlich syndrome (HWWs) is a rare congenital malformation of the female urogenital track characterized by a triad consisting of didelphys uterus, obstructed hemivagina, and ipsilateral renal agenesis. We report 5 consecutive cases of patients diagnosed with HWWs treated in our center. Imaging studies with 2-dimensional/3-dimensional ultrasound and abdominopelvic magnetic resonance imaging were obtained to confirm the diagnosis. The treatment consisted of a 1-step surgical in-office hysteroscopic incision of the vaginal septum using 5 Fr hysteroscopic bipolar electrodes. At the follow-up visit, between 1 and 2 months after the initial procedure, the patients underwent a diagnostic vaginoscopy with excision of exceeding vaginal tissue if needed, performed with a vaginal hysteroscopic approach. In-office hysteroscopic treatment of patients diagnosed with HWWs is a safe and effective, minimally invasive treatment modality that provides symptomatic relief and preserves fertility, avoiding the cost and risks of the use of general anesthesia in an operating room setting. We recommend shifting the management of this challenging condition to the office setting.

RESUMO

AIM: To compare the recurrence of benign endometrial polyps after office hysteroscopic polypectomy performed with a bipolar electrode (BE) or a small diameter hysteroscopic tissue removal system (HTRs). METHODS: From July 2018 to December 2019 we evaluated the charts of 114 asymptomatic fertile women who underwent office hysteroscopic polypectomy, 1 year before, for a single large benign endometrial polyp (size between 10 and 20 mm) using a 4 mm continuous flow hysteroscope with a BE or a 5 mm HTRs. Patients, divided into two groups according to surgical procedure, each performed exclusively by one expert gynecologist, were scheduled for a 12-month postoperative transvaginal sonography to evaluate the recurrence of endometrial polyps. RESULTS: Forty-eight women of the BE group and 42 of the HTRs group were considered for the 1-year transvaginal sonography follow-up. Five polyps were identified in the BE group and three in the HTRs group (5/48 vs 3/42, P = n.s.). All polyps were removed hysteroscopically (in three out of five and in two out of three cases, respectively, in the same places of the previous polypectomy) and evaluated as 'benign' by the pathologist. CONCLUSION: Office hysteroscopic endometrial polypectomy with small HTRs compared to BE revealed at a 1-year follow-up no difference in terms of complete removal and recurrence of polyps. HTRs polypectomy resulted in less pain and significantly quicker time of procedure compared to BE. This data should be kept in mind for patient comfort any time hysteroscopic polypectomy is planned in an office setting.
