A novel technique for the measurement of cervical length in non-pregnant women.

Cervical elongation is considered a risk factor for pelvic organ prolapse treatment failure in uterine preservation surgery. Consensus has not been reached regarding what is considered a normal cervical length, or how to measure it. Our primary aim was to test a new technique for measuring cervical length. We enrolled women undergoing hysterectomy, with or without pelvic organ prolapse (for all indications except cervical tumours/history of cervical operations). Their cervical lengths were measured both by ultrasound and anatomical measurement. The external length of the cervix was measured using Doppler location of the uterine artery near the cervical-uterine junction as the proximal point and compared to the ultrasound measurement of the cervical canal. The uterine specimen was used to record anatomical cervical measurements as well as uterine corpus length. Baseline characteristics such as age, body mass index and pelvic organ prolapse quantification were also collected. Twenty women were eligible for evaluation. We found the average anatomical cervical canal length was (ccAN) 33.95 mm (range ± 9.23) and by external measurement (ceAN) 36.80 mm (range ± 7.54). We found a significant, high-powered correlation between our ultrasound and anatomical measurements in both techniques, as well as between the two ultrasound techniques. We also found a negative correlation between cervical length and women's age (rp = -0.443, P = 0.05). Transvaginal ultrasound measurement of cervical length using the location of the uterine artery was found to have a strong correlation to the anatomical cervical length and can be used for the measurement of normal cervical length.

Primary Ewing’s sarcoma of the uterine cervix: a case report and review of the literature

BackgroundEwing’s sarcoma (ES) is an aggressive cancer of bone and soft tissue, most of which tend to occur in the bone. Extraosseous Ewing’s sarcoma (EES) of the cervix is extremely rare.Case presentationIn the present work, we reported a 39-year-old cervical EES patient with a 2.5*2.1*1.8 cm tumor mass. According to previous literatures, our case is the smallest tumor found in primary cervical ES ever. The patient initially came to our hospital due to vaginal bleeding, and then the gynecological examination found a neoplasm between the cervical canal and partially in the external cervical orifice. The diagnosis of EES was confirmed below: Hematoxylin & Eosin staining (H&E) revealed small round blue malignant cells in biopsy specimens. Immunohistochemistry (IHC) showed the positive staining for CD99, NKX2.2, and FLI1. Disruption of EWSR1 gene was found by fluorescence in situ hybridization (FISH), and the EWSR1–FLI1 gene fusion was determined by next-generation sequencing (NGS). The patient received laparoscopic wide hysterectomy, bilateral adnexectomy, pelvic lymphadenectomy, and postoperative adjuvant chemotherapy and remained disease free with regular follow-up for 1 year.ConclusionsThrough a systematic review of previously reported cervical ES and this case, we highlighted the importance of FISH and NGS for the accuracy of ESS diagnosis, which could assist on the optimal treatment strategy. However, due to the rarity of the disease, there is no standard treatment schemes. Investigation on molecular pathological diagnosis and standardization of treatment regimens for cervical ES are critical to patients’ prognosis.

Vasa Previa and the Role of Fetal Fibronectin and Cervical Length Surveillance: A Review.

Vasa previa is a pregnancy complication that occurs when unprotected fetal blood vessels traverse the cervical os, placing the fetus at high risk of exsanguination and fetal death. These fetal vessels may be compromised by fetal movement and compression, leading to poor oxygen distribution and asphyxiation. Diagnostic tools for vasa previa management and preterm labor (PTL) include transvaginal ultrasound, cervical length (CL) surveillance and use of fetal fibronectin (FFN) testing. These tools can prove to be quite useful as they allow for lead time in the prediction of PTL and spontaneous rupture of membranes which can result in devastating outcomes for pregnancies affected by vasa previa. We conducted a literature review on vasa previa management and the usefulness of FFN and CL surveillance in predicting PTL and found 36 related papers. Although there is limited research available to show the impact of FFN and CL surveillance in the management of vasa previa, there is sufficient evidence to support FFN and CL surveillance in predicting the onset of PTL, which can have devastating consequences for the pregnancies affected. It can be extrapolated that these tools, by helping to determine pregnancies at risk for PTL, could improve management and outcomes in patients with vasa previa. Future studies investigating the management of vasa previa with FFN and CL surveillance to reduce the burden of PTL and its associated comorbidities are warranted.

The categorization of opaque pathologies outside of contrast media in hysterosalpingography which facilitate interpretation: A pictorial review.

Hysterosalpingography (HSG) is a practical and reliable imaging method to evaluate the cervical canal, uterine isthmus, uterine cavity, and fallopian tubes. Using HSG, opaque pathologies outside of contrast media can be detected as well as pathologies of uterus and fallopian tubes. We aim to present and categorize some uncommon and interesting abnormal findings that are located outside of the contrast areas in HSG. This is a pictorial review that depicts various types of HSG images that include opaque pathologies outside of the contrast areas. Images have been extracted from valuable archives collected over 50 yr by professor Shahrzad. A plain pelvic film contains soft tissues of the pelvis, bony structures, artifacts, or foreign bodies. Categorization might easily help the radiologist to interpret the HSG cliché. Opaque pathologies outside of contrast area in HSG can be categorized into 2 groups: "Pelvic Tissue Related" and "Foreign Bodies". Pelvic tissue abnormalities might have a gynecologic or non-gynecologic source. Foreign bodies can be located in the pelvis or outside of the body. HSG is a reliable and inexpensive procedure. Familiarity with the pathologies of pelvic tissues and the accurate interpretation of HSG images are important.

Evidence-based commentary on the diagnosis, management, and further research of degenerative cervical spinal cord compression in the absence of clinical symptoms of myelopathy.

Degenerative cervical myelopathy (DCM) represents the final consequence of a series of degenerative changes in the cervical spine, resulting in cervical spinal canal stenosis and mechanical stress on the cervical spinal cord. This process leads to subsequent pathophysiological processes in the spinal cord tissues. The primary mechanism of injury is degenerative compression of the cervical spinal cord, detectable by magnetic resonance imaging (MRI), serving as a hallmark for diagnosing DCM. However, the relative resilience of the cervical spinal cord to mechanical compression leads to clinical-radiological discordance, i.e., some individuals may exhibit MRI findings of DCC without the clinical signs and symptoms of myelopathy. This degenerative compression of the cervical spinal cord without clinical signs of myelopathy, potentially serving as a precursor to the development of DCM, remains a somewhat controversial topic. In this review article, we elaborate on and provide commentary on the terminology, epidemiology, natural course, diagnosis, predictive value, risks, and practical management of this condition-all of which are subjects of ongoing debate.

Feasibility of Using Intraoperative Neurophysiological Monitoring for Detecting Bone Layer of Cervical Spine Surgery.

Intraoperative neurophysiological monitoring (IONM) as a guide to bone layer estimation was examined during posterior cervical spine lamina grinding. To explore the feasibility of IONM to estimate bone layer thickness. Cervical laminoplasty is a classic operation for cervical spondylosis. To increase safety and accuracy, surgery-assistant robots are currently being studied. It combines the advantages of various program awareness methods to form a feasible security strategy. In the field of spinal surgery, robots have been successfully used to help place pedicle screws. IONM is used to monitor intraoperative nerve conditions in spinal surgery. This study was designed to explore the feasibility of adding IONM to robot safety strategies. Chinese miniature pig model was used. Electrodes were placed on the lamina, and the minimum stimulation threshold of DNEP for each lamina was measured (Intact lamina, IL). The laminae were ground to measure the DNEP threshold after incomplete grinding (Inner cortical bone preserved, ICP) and complete grinding (Inner cortical bone grinded, ICG). Subsequently, the lateral cervical mass screw canal drilling was performed, and the t-EMG threshold of the intact and perforated screw canals was measured and compared. The threshold was significantly lower than that of the recommended threshold of DENP via percutaneous cervical laminae measurement. The DNEP threshold decreases with the process of laminae grinding. The DNEP threshold of the IL group was significantly higher than ICP and ICG group, while there was no significant difference between the ICP group and the ICG group. There was no significant relationship between the integrity of the cervical spine lateral mass screw path and t-EMG threshold. It is feasible to use DENP threshold to estimate lamina thickness. Cervical lateral mass screw canals by t-EMG showed no help to evaluate the integrity.

Cervical elastography using E-Cervix™ for prediction of preterm birth in twin pregnancies with threatened preterm labor

ObjectiveTo evaluate the prediction performance of E-Cervix™ for preterm birth in twin pregnancies with threatened preterm labor. MethodsThis was a single-center retrospective cohort study of twin pregnancies presenting to obstetrics triage for threatened preterm labor (PTL) between 23 0/7 – 33 6/7 weeks who received screening for PTL with transvaginal ultrasound cervical length (TVU CL) and cervical elastography with E-Cervix™ at the time of triage. Cervical elastography parameters were examined and compared between women who delivered preterm and those who did not. The quantification of cervical strain was calculated by a data analysis system that directly analyzes raw data from the region of interest (ROI) and described as hardness ratio (HR), mean strain level within 1 cm from internal (IOS) and external (EOS) os. Results63 twin gestations without prior preterm birth and with threatened PTL between 23 0/7 – 33 6/7 weeks of gestation were included in the study. 27 (42.9 %) had cervical length < 25 mm, and were admitted for true PLT. Out of the 36 women with cervical length ≥ 25 mm, 6 (16.7 %) were admitted. Women with threatened PTL had significantly higher HR compared to those with true PTL (p < 0.01), and significantly lower IOS and EOS. Women who delivered preterm had significantly higher HR compared to those who did not delivery preterm and significantly lower IOS and EOS, in overall cohort, and in the subset of women with true PTL. Incidences of HR < 50 % and < 35 % were statistically significantly higher in women who delivered preterm compared to those who did not (p < 0.01). ConclusionCervical elastography with E-Cervix™ may be useful for assessment of twin gestations presenting to obstetrics triage for threatened PTL.

Characteristics and utility of high-resolution optical coherence microscopy images of endocervical canal lesions.

To investigate optical coherence microscopy (OCM) imaging features and the application value of these high-resolution images for identifying endocervical canal lesions (ECLs), which is a clinical dilemma in cervical cancer screening programs. In total, 520 OCM images were obtained by scanning the cervical canal lesions with an ultra-high-resolution OCM system (204 specimens from 73 patients). The OCM morphologic characteristics of ECLs were observed and summarized, and then 3 researchers performed a diagnostic test of OCM images of cervical canal lesions. The accuracy, sensitivity, specificity, positive predictive value, negative predictive value, 95% confidence interval of each parameter, and interinvestigator agreement (κ) were calculated. Normal endocervix, cysts, squamous metaplasia, high-grade squamous intraepithelial lesions involving glands, and invasive carcinoma had distinct OCM characteristics, which correlated well with corresponding H&E histologic sections. The accuracy, sensitivity, and specificity of the 3 researchers were 90.6%, 89.3% (95% CI, 86.5%-91.7%) and 91.6% (95% CI, 89.2%-93.5%), respectively. The positive predictive value was 90.1% (95% CI, 87.3%-92.4%), and the negative predictive value was 90.9% (95% CI, 88.5%-92.9%), with almost perfect agreement (κ = 0.874). The application of the OCM system in cervical canal lesions is feasible and could help improve detection of occult ECLs in cervical cancer screening programs. This study lays the foundation for further research on OCM in cervical canal lesions in vivo, which also has a potential impact on projecting pathologic evaluation beyond what is currently possible, perhaps globally.

The association between gynecological complaints and the uterine sonographic features in women with a history of cesarean section

PurposeThe aim of this study is to investigate the association between post-cesarean sonographic uterine measures, dysmenorrhea, and bleeding disorders.MethodsThis is a cross-sectional study where 500 women with a history of only one cesarean section (CS) were recruited. A transvaginal transducer, GE RIC6-12-D was used for the acquisition of volumetric datasets 18 ± 7 months postpartum. Uterine length (UL), cervical length (CL), niche length (L), niche depth (D), niche width (W), fibrosis length (FL), fibrosis depth (FD), residual myometrial thickness (RMT), endometrial thickness (EM), scar to internal os distance (SO), anterior myometrial thickness superior (sAMT) and inferior (iAMT) to the scar, and the posterior myometrial thickness opposite the scar (PMT), superior (sPMT), and inferior to it (iPMT) were measured. Logistic regression with odds ratios (OR), 95% confidence intervals (CI) and ROC curves were utilized.ResultsThe proportion of patients with incident post-cesarean bleeding disorders and dysmenorrhoea was 36% (CI 32%, 40%) and 17% (CI 14%, 21%) respectively. Univariate logistic regression showed that only UL was associated with bleeding disorders [OR 1.04 (CI 1.01,10.7) p value 0.005], whereas dysmenorrhea was associated with RMT [OR 0.82 (CI 0.71,0.95) p value 0.008], SO [OR 0.91 (CI 0.86,0.98) p value 0.01], and RMT ratio [OR 0.98 (CI 0.97,0.99) p value 0.03]. Multivariate logistic regression for dysmenorrhoea including SO and RMT remains statistically significant with p values <0.05 and area under the curve of 0.66.ConclusionThere is an association between sonographic appearance of CS scars and dysmenorrhoea. Nevertheless, the association is weak and other biological post-cesarean characteristics should be explored as potential causes.

MODERN VIEWS OF THE PROGRESSION OF CERVICAL NEOPLASIA AFTER DESTRUCTIVE TREATMENTS FOR CERVICAL DISEASES

Diagnosis of cervical intraepithelial neoplasia in women with a history of exocervix ablation is difficult due to the displacement of the junction of the squamous and prismatic epithelium into the cervical canal. Diagnostic significance in these cases belongs to the data of cytological examination of cells obtained with the help of a cyto-brush from the cervical canal. The diagnosis was clarified by coni biopsy. In 20 (17%) of the 70 women followed, CIN and cervical cancer were detected. Patients with ablation exocervixes have a history of developing intracervical neoplasias with the persistence of highly oncogenic types of HPV (human papillomavirus), so they need endocervix cytological control, viral load, and papillomavirus genotype annually as secondary prevention of cervical cancer.

Tocolytic effectiveness of nifedipine in management of preterm labor: A tertiary center experience

Objective: This study aimed to compare the efficacy of nifedipine use in our clinic for treatment of preterm labor with diferent effacement degrees, and to compare our results with the literature. Methods: 440 singleton pregnant women with intact amnionic membrane pregnant women in their 23 and 36 weeks were retrospectively evaluated. Because of different criterias defining preterm labor in the literature, patients were divided into two groups as 4 or over contractions in 20 minutes and cervical opening at 2 cm and/or above and/or effachment at 80% or above (Group A, n=230) and 4 or over contractions in 20 minutes and cervical opening below 2 min and effechment below 80% (Group B, n=210). Descriptive statistics were conducted using chi-square and Mann Whitney U test, and statistically significance was p &lt;0.05. Results: Demographics, reproductive history and pregnancy weeks of the groups were similar. The average time between the start of tocolysis and the birth was 4 times higer in Group B (0.1-99.2, mean 28.4) than that of Group A (0.1-78.9, mean 7.4 days, p&lt;0.001). Delay after tocoloysis at days 1 to 7 was statistically remarkable in Group B (p&lt;0.001, for each). Preterm labor resulting in early birth was more remarkable in Group A in both before 34 weeks and 37 weeks (p&lt;0.001, for each; n=88, 38.3% vs n=36, 17.1% and n=171, 74.3% vs n=98, 46.7%, respectively and n=269/124, 28.2 vs 61.1%). Delay with nifedipine at day 1 (87.5%), day 2 (79.1%), day 3 (74.8%) and day 7 (65.5%) was also compatable with the literature. Conclusions: Nifedipine is an effective tocolytic agent in preterm labor regardless of the effachment degree.

Rescue cervical cerclage in twin pregnancy with spontaneous cervical dilatation at 8-week gestation

AbstractPremature spontaneous cervical dilatation can happen among pregnant women leading to miscarriage, preterm labor, or premature delivery. We present a case of twin pregnancy with spontaneous cervical dilatation and membranes bulging into the vagina at 8-week gestation. A 34-year-old primigravida presented to our clinic with complaints of cramping pain in the lower abdomen. Her per speculum pelvic examination showed evidence of dilated cervical os and amniotic membranes bulging through the cervix into the vagina. Her sonogram suggested a dichorionic diamniotic pregnancy of 8-week gestation. Her TVS examination revealed that the internal os was dilated. Both fetuses were alive with regular fetal heart rate. Rescue cervical cerclage by modified Shirodkar’s technique was done under general anesthesia. She was administered prophylactic antibiotics and tocolytic. She was closely followed up at regular intervals and observed for signs of chorioamnionitis. She delivered at 35 weeks of gestation with two female children with birth weights 2.3 kg and 2.1 kg, respectively.

Obstetricians’ Utilization of Risk Factors for High-Risk Pregnancy to Predict Complicated Pregnancies: How Are Obstetricians Using Risk Factors for High-Risk Pregnancy?

Purpose: The aim of this study was to analyze how obstetricians use risk factors for high-risk pregnancies to predict complicated pregnancies.Methods: Twenty-four obstetricians were surveyed using a questionnaire that included 75 high-risk pregnancy factors identified by the Korean Society of Obstetrics and Gynecology. These factors are used to predict 11 types of complicated pregnancies: preterm labor, preterm premature rupture of membranes, incompetent internal os of the cervix, placenta previa, placenta abruptio, postpartum hemorrhage, preeclampsia/eclampsia, oligohydramnios, polyhydramnios, gestational diabetes mellitus, and intrauterine growth restriction.Results: Obstetricians utilized 65 of the 75 identified high-risk factors to predict 11 types of pregnancy complications. They identified twin pregnancy as the most significant risk factor, followed by chronic hypertension, a history of preterm birth, pregestational diabetes mellitus, advanced maternal age over 40, and a history of preeclampsia and eclampsia. Twin pregnancies were associated with all 11 complicated pregnancies. Ten of the 75 risk factors were not used for predicting complications.Conclusion: This study demonstrated that obstetricians recognized twin pregnancy as a strong risk factor associated with complications of pregnancy. Based on the results of this paper, we expect prediction models for complicated pregnancies to be developed in the future.

Müllerian adenosarcoma with sarcomatous overgrowth and heterologous elements: A case report and literature review

Uterine mullerian adenosarcoma (MA) is a rare biphasic tumour that accounts for less than 0.5% of uterine neoplasms. The age range of presentation is wide, with the median age in the 5th decade of life. It usually has a good prognosis; however, it worsens when it presents with sarcomatous overgrowth, heterologous elements or infiltrates the myometrium.We report the case of a 63-year-old woman presenting with abnormal vaginal bleeding and a sensation of solid material coming out of the cervical canal who was diagnosed with mullerian adenosarcoma with sarcomatous overgrowth (MASO) and presence of heterologous elements after performing a mass biopsy and subsequent hysterectomy.We reviewed the literature, focusing especially on the differential diagnoses to be evaluated, as well as the differences in prognosis and treatment according to whether or not they present histologic features of poor prognosis.

ерсонифицированный подход к диагностике и лечению рецидивирующих форм бактериального вагиноза

According to world statistics, bacterial vaginosis (BV) occupies one of the first places among vaginal diseases. The frequency of its distribution in the population ranges from 12% to 80% and depends on the contingent of women examined. BV develops mainly in women of reproductive age: in 80–87% of women with pathological vaginal discharge and 37–40% of pregnant women. Aim. To evaluate the effectiveness of three-stage therapy for recurrent and combined forms of BV based on the characteristics of the microbiome of the genital tract in women of early reproductive age. Materials and methods. We observed 445 women, who were divided into the following clinical groups. The IP group included 174 (39.10±2.31%) women with a confirmed diagnosis of recurrent BV. The IIP group included 153 (34.38±2.25%) women in whom BV was combined with cervicitis of nonspecific etiology. Group IIIP included 85 (19.10±1.86%) patients with a verified diagnosis of recurrent BV in combination with vulvovaginal candidiasis. The comparison group included 33 (7.42±1.24%) women, whose examination results corresponded to the reference values. Verification of the diagnosis in patients was carried out when contacting the antenatal clinic, based on the anamnesis, the nature of the complaints, and the results of clinical and laboratory examination methods. Laboratory examination included: pH – measurement of vaginal fluid using colpotest; bacterioscopic (urethra, cervical canal, vagina, rectum), bacteriological examination and polymerase chain reaction method in real time characterized the vaginal biotope. Patients with recurrent BV were offered three-stage therapy according to a personalized algorithm we developed, taking into account concomitant vaginal pathology. Results. The data obtained indicated an improvement in the quality of life of patients who underwent a course of three-stage therapy. The clinical effect showed that there were no relapses of the disease in patients of the IIIP group in 83% of cases, in the IIP and IP groups – in 90% and 91% of women, respectively. The highest frequency of relapses after therapy after 6 and 12 months was observed in patients of group IIIP, which amounted to 6% and 8% of Clinical cases (p&lt;0.05). Conclusion. Our data indicate that the use of the proposed diagnostic algorithm and three-stage therapy for recurrent and combined forms of BV made it possible to reduce the frequency of reproductive losses in patients in the prospective study groups: spontaneous miscarriages in early and late gestation – in 6.29, ectopic pregnancies – by 5.54 times, premature births by 3.65 times. The frequency of normal term births in women in the prospective study groups after three-stage therapy increased by 1.4 times.

Elasticity of the Cervix in Relation to Uterus Position.

Strain elastography allows the evaluation of tissue elasticity. Background/Objectives: Tissue elasticity depends on the content and distribution of collagen fibers and is shaped by the applied tensile forces that may differ in uteri with a different angle of flexion of the corpus on the cervix. The objective was to investigate whether the angle of uterine flexion is related to cervical tissue elasticity. Methods: The anterior angle between the longitudinal axis of the uterus corpus and that of the cervix was measured in 275 non-pregnant young women by transvaginal ultrasonography and considered both as an absolute value or categorized as ≤150°, between >150° and ≤210°, and >210°. Strain elastography was used to assess tissue elasticity by placing the probe in the anterior vaginal fornix. Tissue elasticity was evaluated in the middle of the anterior cervical compartment (ACC), in the middle of the posterior cervical compartment (PCC), in the middle portion of the cervical canal (MCC), and at the internal cervical os (ICO). In a sagittal plane MCC was evaluated across the cervical canal, and ACC and PCC at a distance equal between the cervical canal and the outer anterior or posterior part of the cervix. MCC, ACC and PCC were evaluated at equal distance between the ICO and the external cervical os. Elasticity was expressed as a color score ranging from 0.1 (low elasticity) to 3 (high elasticity). Results: The angle of uterine flexion show a negative linear relation with the elasticity of the ACC (p = 0.001) and MCC (p = 0.002) and a positive relation with the elasticity of the PCC (p = 0.054). In comparison to uteri with an angle of flexion of <150°, those with an angle of flexion of >210° had lower elasticity of the ACC (p = 0.001) and MCC (p = 0.001) and higher elasticity of the PCC (p = 0.004). The ACC/PCC and PCC/MCC elasticity ratios were also significantly different (p = 0.001). Conclusions: The angle of uterine flexion is associated with changes in cervix elasticity. Retroflexion is associated with stiffer ACC and MCC and a more elastic PCC. Differences in tissue elasticity suggest structural changes of the cervix that may have implication in variate obstetric and gynecological conditions.

Feasibility of C2 Lamina Screw Placement in a New Zealand Cohort: Computed Tomography Analysis According to Ethnicity and Gender.

Previous analyses have suggested variations in cervical spine canal morphology according to ethnicity, possibly in part due to variations in the posterior elements. The potential for these variations to affect the placement of instrumentation is uncertain. The aim of this study was to report on the feasibility of C2 lamina screw insertion in a New Zealand cohort including analysis of Māori, the indigenous people of New Zealand. A trauma computed tomography database was accessed to identify suitable images. On axial images, where the isthmus was at its widest, the outer diameter (OD) and inner diameter (ID) of the lamina were measured. Screw length was measured from a proposed entry point to the contralateral junction of the lamina and lateral mass. The spinolaminar angle was measured as the angle subtended by the screw trajectory and midsagittal plane. A 5.5-mm OD was accepted as a threshold for the feasibility of lamina screw placement. One hundred eighty-seven images were assessed: 115 New Zealand European and 72 Māori. The mean age of the cohort was 41.9 years (SD 19.6), and most patients (64%) were men. For the entire cohort, mean OD was 6.6 and 6.8 mm on the right and left, respectively; the mean inner diameter was 3.5 and 3.8 mm; mean screw length was 31.5 and 31.5 mm; and mean spinolaminar angle was 46.0° and 46.1°. C2 lamina screw placement was feasible in a majority of patients. Considering only Māori patients, placement was feasible in 96% of right and 94% of left laminae in men but 72% of right and 72% of left laminae in women. In a majority of patients, C2 lamina screw placement is feasible. However, advanced imaging must be carefully assessed preoperatively because data suggest that Māori women may not necessarily have optimal anatomy.Clinical RelevanceCare needs to be taken when assessing and planning surgery inpatients of different ethnicities because variations may exist in the morphology of the posterior elements of C2, leading to variation in optimal fixation strategy.Level of Evidence3.

Late emergency cervical cerclage placement in a patient with early recurrent pregnancy loss and bicorporeal uterus: A case report

Introduction: Uterine Müllerian anomalies are relatively common among the population, affecting approximately 4% of women, and can lead to various pregnancy-related pathologies. Cervical cerclage, a surgical procedure involving the placement of a stitch around the cervix, has been recognized as an optional treatment to mitigate the risk factors associated with these anomalies. Case Report: A 33-year-old woman with a bicorporeal uterus and a history of early recurrent pregnancy loss, who was diagnosed with a cervical os shortening during her second anatomy screening at 22+3 weeks gestation. A cervical cerclage was performed to prevent preterm delivery, and subsequently. An elective cesarean section was conducted at 37+0 weeks of gestation, resulting in the birth of a healthy baby boy. Conclusion: Although the literature about the effectiveness of cervical cerclage in pregnant women with Müllerian anomalies is limited, this case highlights its potential as an effective treatment option.

Effect of Ureaplasma/Mycoplasma genital tract infection on preterm labor.

Genitourinary tract infections in pregnant women are one of the causes of abnormal pregnancy development including miscarriages, premature labor or premature rupture of membranes (PPROM). Atypical bacteria responsible for reproductive tract infections include Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum and Ureaplasma parvum. Identification of pathogens and appropriately selected therapy can improve obstetric outcomes in patients with symptoms of threatened miscarriage or threatened preterm labor. The purpose of our study is to analyze the impact of reproductive tract infections with ureaplasma and mycoplasma bacteria during pregnancy. In the presented study, we retrospectively analyzed the cases of 201 pregnant patients hospitalized in the Obstetrics and Gynecology Department of Poznan Regional Hospital in 2019-2022, who had a swab taken from external os area of the cervix for atypical bacteria - Ureaplasma and Mycoplasma. Only patients with symptoms of threatened miscarriage or threatened preterm labor were included in the study group. Microbiological tests were performed in the hospital laboratory with the Mycoplasma IST 3 test from Biomerieux. We found a higher incidence of preterm labor in patients with symptoms of threatened preterm labor and a genital tract infection with Ureaplasma/Mycoplasma bacteria, compared to patients not infected with Mycoplasma/Ureaplasma - 31.1% vs 20% (p = 0.098). This observation in the case of Ureaplasma/Mycoplasma monoinfection group applied to 6 patients. - 75% of the group. Pregnant patients who had co-infection with other types of bacteria (48 patients in total) gave birth before 37 weeks of pregnancy in 27.1% of cases. We obtained a significant difference (p = 0.007) when comparing groups with positive and negative cultures for Ureaplasma/Mycoplasma by the presence of monoinfection/coinfection and the week of pregnancy in which delivery occurred. We also noted the effect of atypical bacterial infection for PPROM - this complication preceded preterm delivery in 40% of ureaplasma-positive patients, compared to 20% of PPROM without infection. We found a similar rate of preterm labor and pregnancy loss in Ureaplasma/Mycoplasma-positive patients who received antibiotic therapy (35.7%) compared to a group of pregnant women who did not receive treatment (31.6%). Infection of the genital tract with atypical bacteria Ureaplasma and Mycoplasma has a negative impact on the course of pregnancy. Identification of the type of microorganisms in cervical canal secretions of pregnant patients with symptoms of threatened miscarriage or preterm labor seems crucial. The impact of antibiotic therapy though, requires further analysis.

The efficacy and safety of local 5-aminolevulinic acid-based photodynamic therapy in the treatment of cervical high-grade squamous intraepithelial lesion: a single center retrospective observational study.

Typical treatments for cervical high-grade squamous intraepithelial lesion (HSIL) are invasive procedures. However, these procedures often come with several severe side effects, despite their positive effects on cervical HSIL. 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a non-invasive treatment that has been successfully used to treat cervical low-grade squamous intraepithelial lesion (LSIL). In this study, we aimed to further investigate the clinical efficacy and safety of ALA-PDT in the treatment of patients with cervical HSIL. A total of 40 patients aged 20 - 41 years with cervical HSIL and high-risk Human Papilloma Virus (HR-HPV) infections were enrolled in this retrospective study from January 2019 to December 2022. Patients were treated with six times of ALA-PDT at intervals of 7-14 days. Three months after the treatment, the efficacy was evaluated through HPV genotyping and cervical cytology examination. If the cytological result was worse than ASC -US, the patient underwent colposcopy-directed biopsy immediately. Otherwise, patients would receive rigorous follow-up observation. Three months after receiving ALA-PDT treatment, 65% (26/40) of cervical HSIL patients at our center showed complete regression (cytological result: normal; HR-HPV: negative). This rate increased to 82.5% (33/40) at the 12-month follow-up. None of the patients experienced disease progression after ALA-PDT therapy. The risk of persistent HR-HPV infection was 32.5% (13/40) at the 3-month follow-up after ALA-PDT. Multivariate analyses identified cervical canal involvement as an independent risk factor for persistent HR-HPV infection at the 3-month follow-up after ALA-PDT treatment. During the treatment of the 40 patients with ALA-PDT, there were no reports of severe adverse reactions. Only a limited number of patients experienced slight discomfort symptoms. ALA-PDT is safe and effective noninvasive therapy for patients with cervical HSIL and HR-HPV infections. It is particularly suitable for young women, who have been confirmed with cervical HSIL and have demand for fertility protection. Three months after ALA-PDT treatment, if a patient still has either ASC-US cervical cytological result and/or HR-HPV infection, rigorous observation is considered safe for her. Cervical canal involvement is an independent risk factor for persistent HR-HPV infection at the 3-month follow-up after ALA-PDT treatment.
