Delayed diagnosis and treatment of adolescents and young women with suspected endometriosis.

STUDY OBJECTIVE: Early diagnosis and treatment of endometriosis in adolescents and young women is considered essential for improving their quality of life and for prevention of long-term complications. In adult women with endometriosis, significant delays in diagnosis and medical or surgical treatment have been described. Our study aimed to investigate the delay in diagnosis and treatment of adolescents and young women with suspected endometriosis. METHODS: A retrospective study of adolescents and young women (12-22 years-old) who were evaluated for suspected endometriosis at the endometriosis clinic in the Shamir medical center between January 2017 and December 2022. All patients were referred by their primary care gynecologists. The evaluation in the endometriosis clinic included targeted history, physical exam and a focused ultrasound survey for endometriosis (performed trans-abdominally in all cases, and trans-vaginally in sexually active women). RESULTS: Out of 400 women with suspected endometriosis evaluated in our endometriosis clinic during the study period, 68 were adolescents and young women <22 years old. Their mean age at time of evaluation for endometriosis was 18 ± 2.5 years, and the mean time-period from onset of symptoms to the endometriosis evaluation was 4.0 ± 2.9 years. Their most common symptoms were dysmenorrhea (in 61 cases, 89.7 %), followed by gastrointestinal symptoms (in 32 cases, 47.1 %). In 30 (44.1 %) cases, hormonal treatment was prescribed by the primary care gynecologist prior to their appointment in the endometriosis clinic. On comparison of patients with delay of <4 years (N = 31) versus ≥4 years (N = 37) from symptom onset to the endometriosis evaluation, patients with shorter duration of symptoms were more likely to decline any hormonal treatment for endometriosis while patients with longer duration of symptoms were more likely to accept the recommendation for hormonal treatment (16.2 % versus 0 %, p = 0.02, and 83.8 % versus 100 %, p = 0.03, respectively). CONCLUSION: Adolescents and young women with suspected endometriosis may experience significant delays in diagnosis and medical care, similar to adult patients.

Managing patients with suspected postpartum retained products of conception using a novel sonographic classification.

BACKGROUND: Suspicion of retained products of conception (RPOC) often arises after delivery and still poses a diagnostic and management challenge. PURPOSE: To prospectively evaluate a sonographic classification for the management of patients with suspected RPOC after delivery. MATERIAL AND METHODS: Based on grayscale and Doppler ultrasound parameters, patients were classified into high, moderate, or low probability of RPOC. For the low and moderate probability groups, an ultrasound follow-up at the end of the puerperium was recommended. For the high probability group, a follow-up examination was conducted 10-14 days after the first ultrasound, and patients with persistent high probability findings were referred for surgical intervention. RESULTS: The sample was composed of 215 patients at risk of RPOC. Of these, 100, 93, and 22 patients were classified as having a low, moderate, or high probability of RPOC, respectively. Rates of RPOC were 55%, 2%, and 2% in the high, moderate, and low probability categories, respectively. When the categorization was based on the most recent ultrasound obtained during the puerperium, the adjusted RPOC prevalence rates were 71% in the high, 6% in the moderate, and 0% in the low probability groups. CONCLUSION: This study confirms the effectiveness of our sonographic classification for managing patients with suspected RPOC after delivery. In all three categories, it is recommended to adhere to a conservative management protocol in clinically stable women until the end of the puerperium. This approach provides good predictability for RPOC and can reduce unnecessary surgical interventions.

Tubal stump pregnancy after salpingectomy-Does the time interval from surgical intervention to conception matter?

AIM: Ectopic pregnancy implantation on the tubal stump after salpingectomy is a rare location for extrauterine pregnancy, whose pathogenesis is still unknown. The purpose of this study was to examine whether the time interval elapsed from salpingectomy may predispose the embryo to implantation on the tubal stump in the next pregnancy subsequent to tube removal. METHODS: Nine women operated for stump pregnancy (study group) between 2008 and 2019 were retrospectively identified. For each case in the study group, 12 consecutive cases that underwent laparoscopic salpingectomy constituted the control group. A sample size of 100 control patients was calculated to achieve statistical power (97.8%) and an α of 0.05. The control groups were triple-matched with the study group for patients' age, indications for salpingectomy (tubal pregnancy or hydrosalpinx prior to in vitro fertilization treatment) and mode of conception of the subsequent pregnancy following salpingectomy. RESULTS: Nine women underwent surgery for stump pregnancy during the study period. All women had a surgical history of laparoscopic salpingectomy. The time interval from prior salpingectomy to subsequent pregnancy was significantly shorter in study group than in the control group (4.3 ± 2.1 months vs. 15.6 ± 13.7 months, respectively, p = 0.016). CONCLUSION: A possible association between the short time interval from prior salpingectomy to ectopic implantation on the tubal stump in the subsequent pregnancy was found. The clinical implications of these findings and in particular whether patients should be advised to wait at least 4 months from the salpingectomy to the subsequent pregnancy remain unclear.

Analgesic efficacy of virtual reality for acute pain in amniocentesis: A randomized controlled trial.

BACKGROUND: To evaluate the efficacy of virtual reality (VR) as a distraction technique in the management of acute pain and anxiety during amniocentesis. STUDY DESIGN: A randomized controlled trial was conducted between September 2020 and October 2020 involving 60 women undergoing mid-trimester amniocentesis. Thirty women were assigned randomly to the VR intervention (immersive video content as a distraction method) group and 30 to the standard care group using a predetermined randomization code. The primary outcome measure was the visual analog scale (VAS) pain score, along with the women's ratings of their extent of anxiety experienced during the procedure. The VAS consisted of a 10 cm line ranging from 0 to 10 (anchored by 0 = no pain and 10=very severe pain). Anxiety was assessed on Spielberger's state-trait anxiety inventory (STAI) questionnaire. RESULTS: The patients' characteristics and obstetric data were similar in both groups. The ratings on the VAS indicated that the VR intervention was associated with significantly less pain than the ratings in the standard of care group; namely, 2.5 ± 1.5 vs. 3.8 ± 1.7, respectively (95 % CI 0.44-2.13; p = 0.003). There were no significant differences in maternal anxiety levels before and after amniocentesis. CONCLUSION: The VR intervention as a distractive technique emerged as effective in reducing pain during amniocentesis. It is easy to use, relatively inexpensive, has the advantage of no serious side effects, and may decrease the fear of pain that can affect patients' experiences and compliance with this procedure.

Analgesic Efficacy of Intrauterine Lidocaine Flushing in Hysterosalpingo-foam Sonography: A Double-blind Randomized Controlled Trial.

STUDY OBJECTIVE: To evaluate the efficacy of flushing the uterine cavity with lidocaine before hysterosalpingo-foam sonography (HyFoSy) to reduce procedure-related pain. DESIGN: A double-blind randomized controlled trial was conducted at the Department of Obstetrics and Gynecology, Shamir Medical Center, Israel between June 2020 and September 2020 involving 80 women undergoing a HyFoSy procedure. SETTING: University-affiliated medical center. PATIENTS: A total of 40 women were assigned randomly to the lidocaine group and 40 to the saline (placebo) group using a predetermined randomization code. Intrauterine instillation before the procedure consisting of either lidocaine 2% or normal saline alone was conducted, respectively. INTERVENTIONS: The primary outcome measure was the visual analog scale (VAS) pain score during the phase of intrauterine foam instillation reported by the women after the procedure. The VAS consisted of a 10-cm line ranging from 0 to 10 (anchored by 0 = no pain and 10 = very severe pain). On the basis of the VAS scores, the pain level ratings were classified as mild (rated 1-3), moderate (4-6), or severe (7-10). MEASUREMENTS AND MAIN RESULTS: The patient characteristics and obstetric data were found to be similar in both groups. Comparison of the VAS pain scores experienced during the procedure showed that women in the lidocaine flushing group rated the procedure less painful than the women in the saline group (3.0 ± 1.3 vs 6.3 ± 1.5, respectively; p = .001). The incidence of severe pain was significantly lower in the lidocaine group than the saline group (2.5% and 45.0%, respectively, p = .001). CONCLUSION: Lidocaine flushing of the uterine cavity before HyFoSy significantly decreased the pain known to be caused by this procedure and had the advantage of no side effects. It is easily applied, relatively inexpensive, and may affect compliance with this procedure.

Is Hysteroscopy the Best Surgical Approach for Removal of Retained Products of Conception Following Surgical Termination of Pregnancy?

OBJECTIVE: To investigate the rates of intrauterine adhesion following hysteroscopy for removal of RPOC associated with surgical termination of pregnancy. METHODS: We conducted a retrospective cohort study of all cases of removal by hysteroscopy of RPOC associated with surgical termination of pregnancy carried out at the Yitzhak Shamir (Assaf Harofe) Medical Center from January 2013 to December 2018. The rates of postoperative intrauterine adhesion were assessed by follow-up hysteroscopy. RESULTS: Our study involved 85 cases of removal by hysteroscopy of RPOC associated with surgical termination of pregnancy. The mean size of the RPOC was 1.9 ± 0.9 cm, and the mean time from termination of pregnancy to hysteroscopy was 1.5 ± 0.9 months. Two patients (2.4%) were readmitted for postoperative complications (fever). Postoperative follow-up information was available for 49 cases (57.6%). A total of 47 of these women had a normal uterine cavity (95.9%) while 2 women (4.1%) were diagnosed with mild intrauterine adhesions. CONCLUSIONS: Hysteroscopy for removal of RPOC following surgical termination of pregnancy is associated with low rates of postoperative intrauterine adhesions. Additional studies may determine whether this is the procedure of choice in these cases.

Gynecology and Oncology Fetal Myofibromatosis: A Challenge for Prenatal Diagnosis Mini Review of the English Literature.

IMPORTANCE: Infantile myofibromatosis (IM) is a benign neoplasm with a reported incidence of 1:150,000. The "solitary" type is characterized by a single lesion in the skin, muscle, or bone, whereas the "multicentric" type may also involve the viscera. OBJECTIVE: This report describes the prenatal diagnosis of IM and recommendations for future pregnancy follow-up. EVIDENCE ACQUISITION: This systematic search of the English literature yielded 8 reports documenting prenatal diagnosis of IM between 1999 and 2018. RESULTS: Fetal age at diagnosis ranged from 13 to 38 weeks of gestation. Seven cases were diagnosed in the third trimester (30-34 weeks). Five cases were of the "solitary" type, and all successfully underwent surgical removal of the tumor with a good outcome. Three were of the "multicentric" type, and the 1 infant presenting with diffuse disease died several weeks after delivery. CONCLUSION AND RELEVANCE: The prenatal diagnosis of IM is often not made until the third trimester following a normal second-trimester anomaly scan, likely due to development of this lesion over time. Women should be referred for genetic counseling and consideration of preimplantation genetic diagnosis following the delivery of an affected child with the autosomal recessive form of the disorder and identified causative pathogenic variants.

Two-step hysteroscopy for management of morbidly adherent retained products of conception.

PURPOSE: Retained products of conception (RPOC) may occur as the result of a morbidly adherent placenta. In these cases, the hysteroscopic removal of RPOC may be technically challenging, and may require more than one hysteroscopic procedure. We sought to compare the clinical, surgical, and postoperative characteristics of cases managed by either a one-step hysteroscopy procedure or a two-step hysteroscopy approach. METHODS: A retrospective review of all RPOC cases managed by hysteroscopy from 1/2013 to 3/2018. We included cases of RPOC occurring following delivery and medical or surgical pregnancy terminations. The rates of postoperative intrauterine adhesions were assessed by office hysteroscopy. RESULTS: A two-step procedure was required in 11 (3.9%) of the 358 women who underwent hysteroscopy for removal of RPOC during the study period. Comparison between the two-step and the one-step procedure groups revealed that the women in the two-step group were significantly older and the mean RPOC size was significantly larger (35.5 ± 4.1 years versus 30.7 ± 5.9 years, respectively, p = 0.01, and 38.6 ± 9.8 mm versus 22.3 ± 7.5 mm, p < 0.001, respectively). While the rates of intraoperative complications were similar between groups, readmission for postoperative fever was more common in the two-step group (18.2% versus 2.0%, respectively, p = 0.03). Postoperative intrauterine adhesions were diagnosed in 20.0% and 5.2%, respectively (p = 0.05). CONCLUSIONS: The two-step hysteroscopic approach enabled the complete removal of larger RPOC masses without the use of uterine curettage. The women who underwent the two-step procedure, however, were at increased risk for postoperative fever and postoperative intrauterine adhesions.

Postpartum retained products of conception: Retrospective analysis of the association with third stage of labor placental complications.

OBJECTIVE: To compare the prevalence of postpartum retained products of conception (RPOC) among parturients with a history of third stage of labor placental complications and parturients without those complications. STUDY DESIGN: All women operated for postpartum RPOC following vaginal delivery by hysteroscopy or suction curettage between January 2013 and December 2017 were included in the study. Their medical records were reviewed for the occurrence of third stage of labor placental complications (including early postpartum hemorrhage treated with uterotonics, manual separation of the placenta, and revision of the uterine cavity for removal of cotyledons). RESULTS: The study cohort included 172 women operated for postpartum RPOC following vaginal delivery by operative hysteroscopy (143 cases, 83.1%) or by suction curettage (29 cases, 16.9%). Third stage of labor placental complications were reported in 65 (37.8%) cases, while 107 (62.2%) women had an uncomplicated third stage of labor. When considering all vaginal deliveries in our institution during the study period, the risk for RPOC was significantly higher among parturients with third stage of labor placental complications compared to those with an uneventful third stage of labor (3.7% versus 0.3%, p < 0.001, Odds ratio = 12.5, 95% confidence interval 9.0-17.3). CONCLUSION: Postpartum RPOC following vaginal delivery were more common in parturients with third stage of labor placental complications. However, the majority of postpartum RPOC cases were diagnosed in women reported to have an uncomplicated third stage of labor. Thus, focused postpartum ultrasound follow-up of women considered at risk for RPOC will not identify all cases.

[PRE-ECLAMPSIA: A NEW TEST FOR AN OLD DISEASE].

INTRODUCTION: In the western world, pre-eclampsia, diagnosed in 3-5% of pregnant women, is a major cause of maternal and fetal morbidity and mortality. Once pre-eclampsia is diagnosed, the only effective treatment is delivery. There are known historical risk factors for the development of pre-eclampsia, however only 30% of the women who will develop pre-eclampsia are identified based on their presence. Recently, new first trimester algorithms for the prediction of pre-eclampsia were developed, based on the observation that pregnant women who develop pre-eclampsia have imbalanced placental angiogenic factors and that failure of the trophoblastic migration may change the flow in the uterine arteries. These algorithms include maternal history and demographics, biochemical and clinical markers (mean arterial pressure, uterine artery flow PLGF, PAPP-A, PP-13). The combination of early diagnosis of a high risk group together with promising evidence that simple preventive measures, such as low-dose aspirin and calcium supplements may prevent pre-eclampsia or change its appearance leads to the idea that we are on the verge of a new era regarding detection and prevention of pre-eclampsia.

Termination of pregnancy due to fetal abnormalities performed after 32 weeks' gestation: survey of 57 fetuses from a single medical center.

OBJECTIVE: To assess fetal abnormalities leading to very late termination of pregnancy (VLTOP) performed after 32 weeks' gestation. METHOD: The study population included all pregnant women with singleton pregnancy that underwent VLTOP in our institute because of fetal indications between the years 1998 and 2015. RESULTS: Fifty-seven cases (2.0%) were at ≥32 weeks' gestation and are the subjects of the current study. Our VLTOP cases were subdivided into four categories according to the sequence of events that led to the decision for VLTOP: (1) No routine prenatal screening with an incidental fetal finding discovered after 32 weeks' gestation (9 fetuses ∼16%); (2) Routine early prenatal care raised suspicion of abnormalities, and the final diagnosis was established by additional tests (8 fetuses, ∼14%); (3) Developmental findings detected during the third trimester (21 fetuses; ∼37%), and (4) fetal abnormalities that could have been detected earlier during pregnancy (19 fetuses; ∼33%). CONCLUSIONS: The two categories in which the pregnant women did not underwent any fetal evaluation (i.e. group 1) or those that could have been detected earlier (i.e. group 4) consists ∼49% from our cohort in which VLTOP could have been avoided.

Evaluation of the impact of vasa previa on feto-placental hormonal synthesis and fetal growth.

INTRODUCTION: A vasa previa (VP) refers to aberrant chorionic vessels which can either connect the chorionic plate to a velamentous cord (type I) or a succenturiate or accessory lobe to the main placental mass (type II). METHODS: We performed retrospective cohort study of 32 singleton pregnancies diagnosed with VP. The levels of maternal serum alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG) and unconjugated estriol (uE3) were measured at 15-18 weeks as part of the triple test screening for Trisomy 21. The data were subdivided according to the type of VP and compared with those of a control group with central cord insertion and no succenturiate or accessory placental lobe. RESULTS: Twenty one (65.6%) parturient women presented with VP type I and 11 (34.4%) with VP type II. The mean birthweight and placental weight was significantly higher in pregnancies with VP type II than in pregnancies with VP with VP type I (3037.3±400.9 gr vs 2493.5±491.6 gr; p=0.004 and 511.0±47.2 gr vs 367.1±64.3 gr; p<0.0001; respectively). The mean hCG level in VP type II was significantly (p<0.001) higher than those with type I (2.38MoM vs 1.17MoM) and compared to controls (2.38MoM vs 0.99MoM). CONCLUSIONS: There is no obvious impact on both placental and fetal growth in VP type II. By contrast, VP type I is associated with slower feto-placental growth secondary to impaired development and biological functions of the placenta during the first half of pregnancy.

Cesarean Scar Pregnancy and Morbidly Adherent Placenta: Different or Similar?

BACKGROUND: Growing evidence suggests that cesarean scar pregnancy (CSP) and morbidly adherent placenta (MAP) may represent a continuum of the same disease. OBJECTIVES: To investigate and compare the prior risk factors in women with either CSP or MAP. METHODS: The study included 33 women diagnosed with CSP in our department between 2006 and 2014. For each CSP case, two pregnant patients with MAP were matched for hospitalization date from delivery ward records, constituting the control group. RESULTS: In both groups, maternal age, parity, and previous early and late abortions were similar. The rate of conception by assisted reproductive technologies was 9% in both groups. Although the number of previous cesarean sections was statistically different between CSP versus MAP (2.0 ± 1.0 vs. 1.0 ± 1.0, respectively, P = 0.006), the leading indication of previous cesarean section was breech presentation in both groups (28.1% and 27.8%, respectively, P > 0.05). CONCLUSIONS: CSP and MAP share similar prior risk factors. Due to high morbidity in both diseases, further research is needed toward reducing the known etiological factors contributing to the growing number of both complications.

Hysteroscopic removal of retained products of conception following first trimester medical abortion.

STUDY OBJECTIVE: To investigate the use of operative hysteroscopy instead of traditional curettage in women with retained products of conception (RPOC) following first trimester medical abortion, with the aim of reducing post-operative intrauterine adhesions. DESIGN: Retrospective study. SETTING: Gynecology department in a University affiliated hospital. PATIENTS: All women treated by hysteroscopy for RPOC following first trimester medical abortion using the mifepristone-misoprostol protocol for pregnancy termination or the misoprostol protocol for early missed abortion from January 2013 to August 2016. INTERVENTION: Operative hysteroscopy for removal of RPOC. Post-operative intrauterine adhesions were assessed by diagnostic office hysteroscopy after 6-8 weeks. MEASUREMENTS AND MAIN RESULTS: 50 cases were identified. The mean time from medication administration to the operative hysteroscopy was 1.7 ± 0.7 months. Operative hysteroscopy with blunt use of the resectoscopic loop was used to remove all specimens, and all procedures were completed without intra-operative complications. Two patients (4.0%) were readmitted for fever. Pathology confirmed the presence of RPOC in 45 (90.0%) cases. On follow-up office hysteroscopy, a normal uterine cavity without evidence of intrauterine adhesions was seen in 29/29 (100%) women. CONCLUSION: Hysteroscopy for removal of RPOC following medical abortion is associated with low rates of complications and post-operative intrauterine adhesions.

Fetal abnormalities leading to termination of twin pregnancies: the 17-year experience of a single medical center.

OBJECTIVE: To assess fetal abnormalities leading to termination of pregnancy (TOP) performed in twin pregnancies. METHOD: The current study consisted of all women with dichorionic twin pregnancies (study group) who underwent TOP due to fetal abnormalities in our institute from 1999 to 2015. The data were compared to our registry of all parturient women with a singleton pregnancy (control group) that underwent TOP due to fetal anomalies at the same period. RESULTS: There were 2495 cases of TOP because of fetal indications during the study period. Of them, 86 (3.4%) and 2409 (96.6%) were from the study and control group, respectively. Structural anomalies were the leading indication for TOP in twins compared with singleton pregnancies (81.4% versus 50.9%, respectively, p < 0.0001). For twins, the leading indication for TOP was central nervous system (CNS) abnormalities and it was more common compared with singleton pregnancies (26.1% versus 12.2%, respectively, p < 0.0001). This was followed by chromosomal/genetic abnormalities (16.3% versus 40.4%, respectively, p < 0.0001). CONCLUSIONS: We found a different distribution for fetal anomalies leading to TOP in twins versus singleton pregnancies. The main indication for TOP in the study group was structural malformations, with a predominance of CNS abnormalities.

Prenatal ultrasound charts of orbital total axial length measurement (TAL): a valuable data for correct fetal eye malformation assessment.

OBJECTIVE: To construct prenatal age-specific reference intervals using ultrasound measurement of total axial length (TAL) in normal fetuses for assessing microphthalmia. METHOD: Prospective cross-sectional study of fetuses assessed at a prenatal ultrasound unit between 2011 and 2014. The study cohort comprised 309 pregnant women attending for routine fetal biometry, viability, or anomaly scan between 14 and 41 weeks of gestation. Only singleton viable fetus with normal anatomy, adequate amniotic fluid, accurate gestational age, and no maternal medical complications of pregnancy were enrolled. Biometric measurements were obtained in the axial plane in all the fetuses. Those measurements and the relevant gestational age were registered in a computerized database. RESULTS: A linear growth function was observed between gestational age and bi-orbital diameter (r(2) = 0.95; p < 0.001), ln (TAL) (r2 = 0.89; p < 0.001), OD (r(2) = 0.86; p < 0.001), and IOD (r2 = 0.79; p < 0.001). Tables showing the 5th, 50th, and 95th centiles of orbital parameters were created based on the reference interval charts. CONCLUSIONS: Ultrasound measurement of the fetal TAL ocular distance is feasible. This may assist the multidisciplinary team in the evaluation of fetal eye abnormalities that might be expressed by deviation in TAL.

Second trimester ultrasound prenasal thickness combined with nasal bone length: a new method of Down syndrome screening.

OBJECTIVE: To evaluate ultrasound prenasal thickness (PT) as a way of enhancing the Down syndrome (DS) screening performance of second-trimester nasal bone (NB) length measurement. METHODS: Twenty-one DS and 500 normal fetuses were scanned at 14-27 weeks' gestation. The affected karyotype was known to the person performing the scan. Both PT and NB were measured in a mid-sagittal position and results were expressed in multiples of the normal gestation-specific median (MoM). Gaussian modelling was used to predict the performance of routine screening. RESULTS: Among DS fetuses, the PT median was 1.35 MoM, a highly statistically significant increase compared with the unaffected pregnancies (p < 0.0001, Wilcoxon Rank Sum Test, two-tailed). The NB median was 0.87 MoM (p < 0.0005) and the ratio PT/NB median was 1.51 MoM (p < 0.0001). In the normal fetuses, the two markers were positively correlated (0.25, p < 0.0001), whereas in the DS fetuses there was a non-significant negative correlation (-0.24, p = 0.33). For a 5% false-positive rate, the model predicted detection rate was 70% for PT and NB compared with 43% for NB alone. CONCLUSION: In the second trimester, PT is increased on average in DS fetuses. Combining PT and NB measurement could yield a higher screening detection rate than NB alone. Confirmation of our findings in a series of women scanned before the karyotype was known is needed before the method can be clinically implemented.
