Ovarian tissue cryopreservation for fertility preservation before hematopoietic stem cell transplantation in patients with sickle cell disease: safety, ovarian function follow-up, and results of ovarian tissue transplantation.

PURPOSE: To describe the experience of performing ovarian tissue cryopreservation (OTC) before hematopoietic stem cell transplantation (HSCT), among girls/women with severe sickle cell disease (SCD)(SS or S/ß0-thalassemia) who are, besides the usual surgical risk, at risk of SCD-related complications during the fertility preservation procedure for improving their counseling and management. METHODS: This retrospective study included 75 patients (girls/women) with SCD who have had OTC before myeloablative conditioning regimen (MAC) for HSCT. Characteristics of patients and data on OTC, ovarian status follow-up, and results of ovarian tissue transplantation (OTT) were collected in medical records. RESULTS: At OTC, the median (IQR 25-75; range) age of the patients was 9.6 (6.9-14.1; 3.6-28.3) years, 56/75 were prepubertal, and no SCD or surgery-related complications occurred. The median follow-up post-HSCT was > 9 years. At the last follow-up, among prepubertal patients at HSCT, 26/56 were ≥ 15 years old and presented with a premature ovarian insufficiency (POI), except 2, including the patient who had received an OTT to induce puberty. Eight were 13-15 years old and presented for POI. The remaining 22 patients were under 13. Among the 19 patients who were menarche at HSCT, 2 died 6 months post-HSCT and we do not have ovarian function follow-up for the other 2 patients. All the remaining patients (n = 15) had POI. Five patients had OTT. All had a return of ovarian function. One patient gave birth to a healthy baby. CONCLUSION: OTC is a safe fertility preservation technique and could be offered before MAC independent of the patient's age.

Does hyaluronic acid gel reduce intrauterine adhesions after dilation and curettage in women with miscarriage? A Multicentric randomized controlled trial (HYFACO Study).

BACKGROUND: Miscarriage is a frequent problem that requires dilation and curettage in 30% of cases. This routine surgery may lead to intrauterine adhesions and severe infertility. Hyaluronic acid gel is known to reduce intrauterine adhesions after hysteroscopic surgery. OBJECTIVE: This study aimed to evaluate the rate of intrauterine adhesions after dilation and curettage for miscarriage with and without hyaluronic acid gel. STUDY DESIGN: This was a multicentric (9 hospitals in France), prospective, open-label randomized trial. Patients who had a miscarriage between weeks 7 and 14 of gestation, required dilation and curettage, and wanted another pregnancy were eligible for the study. Women were randomly assigned in a 1:1 ratio to surgery alone (control group) or surgery with intrauterine instillation of hyaluronic acid gel (gel group). An office hysteroscopy was planned at 6 to 8 weeks after surgery. The primary endpoint was the rate of intrauterine adhesions during this office follow-up hysteroscopy. Two different follow-up fertility surveys were sent at 6 months and 1 year after the end of the intervention, respectively. RESULTS: Among the 343 patients who had curettage, 278 had hysteroscopy. After multiple imputation, the rate of intrauterine adhesions was lower in the gel group than in the control group (9.1% vs 18.4%, respectively; P=.0171). Among the 110 responders to the surveys, the overall pregnancy rate at 12 months after surgery was 64.5% (71/110), and similar in both groups (57.4% [27/47] in the control group vs 69.8% [44/63] in the gel group; P=.1789). CONCLUSION: Intrauterine instillation of hyaluronic acid gel reduces the rate of intrauterine adhesions in women treated with dilation and curettage for miscarriage.

Cesarean scar pregnancy with deep serosal invasion at 16 weeks: Uterus-sparing surgery with posterior hysterotomy after transcatheter arterial embolization.

We report a case of cesarean scar pregnancy at 16 weeks. Magnetic resonance imaging confirmed the isthmic ectopic location with an empty fundus and a high suspicion of placental invasion to the anterior myometrium. Because of pelvic pain, bleeding and the major risks of hysterectomy, a decision was made to terminate the pregnancy. After a preventive pelvic artery embolization, we performed an unusual posterior isthmic hysterotomy for the extraction of the fetus, followed by conservative management of the placenta. Bleeding loss was 300 mL, and no complication was reported. Successive magnetic resonance imaging was planned and 6 months later, there were no placental remnants. At 7 months, an office hysteroscopy revealed a normal uterine cavity. In case of cesarean scar pregnancy in the second trimester with an emergency need to interrupt pregnancy, posterior hysterotomy with conservative treatment of placenta may be an option to avoid massive bleeding and hysterectomy.

Effectiveness of degradable polymer film in the management of severe or moderate intrauterine adhesions (PREG-2): a randomized, double-blind, multicenter, stratified, superiority trial.

OBJECTIVE: To study the effectiveness of a new intrauterine degradable polymer film (Womed Leaf) in the management of moderate to severe intrauterine adhesions (IUA). DESIGN: PREG-2 study was a multicenter, double-blind, randomized, controlled, stratified, two-arm superiority clinical trial conducted in 16 centers in seven countries. SETTING: Not applicable. PATIENT(S): Patients ≥18 years scheduled for hysteroscopic adhesiolysis because of symptomatic severe or moderate adhesions (according to American Fertility Society [AFS] IUA score) were considered eligible for the study. INTERVENTION(S): After adhesiolysis, patients were randomized at a 1:1 ratio to either have a Womed Leaf film inserted (intervention group) or not (control group). MAIN OUTCOME MEASURE(S): The primary effectiveness endpoint of the study was the change in AFS IUA score on second-look hysteroscopy (SLH), assessed by an independent evaluator, and compared with baseline. Information on the rate of no IUA and responder rate was collected as secondary effectiveness outcomes, while reported adverse events and patient-reported outcomes as safety and tolerability measures. RESULT(S): Between October 26, 2021, and September 28, 2023, a total of 160 women were randomized (Womed Leaf: n = 75 and controls: n = 85). The reduction in IUA AFS score on SLH was significantly higher in the intervention compared with the control group (mean 5.2 ± 2.8 vs. 4.2 ± 3.2). Similarly, the absence of adhesions on SLH was significantly higher in the intervention group (41% vs. 24%; odds ratio, 2.44; confidence interval, 1.161-5.116). None of the reported adverse events were serious or considered related to the device. CONCLUSION(S): Womed Leaf is effective and safe in the management of symptomatic severe or moderate IUAs. CLINICAL TRIAL REGISTRATION NUMBER: Clinicaltrials.gov identifier: NCT04963179.

Giant intrahepatic venous malformation with localized intravascular coagulopathy. Follow-up and treatment during pregnancy.

Intrahepatic lesions in adults, commonly named hepatic hemangioma, should be called Intrahepatic Venous Malformations (IHVM), or Giant Intrahepatic Venous Malformations (GIHVM) when larger than 10 cm according to the ISSVA classification (International society study group for vascular anomalies). Localized coagulation disorders (LIC) in patients with venous malformations are quite commonly associated in venous malformations, they result in decreased fibrinogen (< 2g/l) and elevated d-dimers (> 1500 ng/ml) and might be responsible of intralesional thrombotic, pain or bleeding episodes.We report a case report of a 41 y/o patient that presented with right hypochondrium pain episodes discovering an unknown GIHVM on ultrasound imaging with a prior history of uterine bleeding episodes and multiples miscarriages.On laboratory work up the patient presented an associated localized Intravascular Coagulation (LIC) with the GIHVM. As the patient desire to become pregnant was important our multidisciplinary clinic allowed a pregnancy with close clinical, biological and imaging monitoring and follow up. Early initiation of low molecular weighted heparin (LMWH) successfully allowed an uncomplicated term pregnancy and delivery. Intrahepatic lesion stability was achieved and prevented progression from LIC to diffuse intravascular coagulation disorder (DIC)..

A Framework Proposal for Quality and Safety Measurement in Gynecologic Emergency Care.

OBJECTIVE: To define and assess the prevalence of potentially life-threatening gynecologic emergencies among women presenting for acute pelvic pain for the purpose of developing measures to audit quality of care in emergency departments. METHODS: We conducted a mixed-methods multicenter study at gynecologic emergency departments in France and Belgium. A modified Delphi procedure was first conducted in 2014 among health care professionals to define relevant combinations of potentially life-threatening conditions and near misses in the field of gynecologic emergency care. A prospective case-cohort study in the spring of 2015 then assessed the prevalence of these potentially life-threatening emergencies and near misses among women of reproductive age presenting for acute pelvic pain. Women in the case group were identified at 21 participating centers. The control group consisted of a sample of women hospitalized for acute pelvic pain not caused by a potentially life-threatening condition and a 10% random sample of outpatients. RESULTS: Eight gynecologic emergencies and 17 criteria for near misses were identified using the Delphi procedure. Among the 3,825 women who presented for acute pelvic pain, 130 (3%) were considered to have a potentially life-threatening condition. The most common diagnoses were ectopic pregnancies with severe bleeding (n=54; 42%), complex pelvic inflammatory disease (n=30; 23%), adnexal torsion (n=20; 15%), hemorrhagic miscarriage (n=15; 12%), and severe appendicitis (n=6; 5%). The control group comprised 225 hospitalized women and 381 outpatients. Diagnostic errors occurred more frequently among women with potentially life-threatening emergencies than among either hospitalized (odds ratio [OR] 1.7, 95% CI 1.1-2.7) or outpatient (OR 14.7, 95% CI 8.1-26.8) women in the control group. Of the women with potentially life-threatening conditions, 26 met near-miss criteria compared with six with not potentially life-threatening conditions (OR 25.6, 95% CI 10.9-70.7). CONCLUSIONS: Potentially life-threatening gynecologic emergencies are high-risk conditions that may serve as a useful framework to improve quality and safety in emergency care.

A snapshot of the Covid-19 pandemic among pregnant women in France.

OBJECTIVE: To describe the course over time of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in French women from the beginning of the pandemic until mid-April, the risk profile of women with respiratory complications, and short-term pregnancy outcomes. METHODS: We collected a case series of pregnant women with COVID-19 in a research network of 33 French maternity units between March 1 and April 14, 2020. All cases of SARS-CoV-2 infection confirmed by a positive result on real-time reverse transcriptase polymerase chain reaction tests of a nasal sample and/or diagnosed by a computed tomography chest scan were included and analyzed. The primary outcome measures were COVID-19 requiring oxygen (oxygen therapy or noninvasive ventilation) and critical COVID-19 (requiring invasive mechanical ventilation or extracorporeal membrane oxygenation, ECMO). Demographic data, baseline comorbidities, and pregnancy outcomes were also collected. RESULTS: Active cases of COVID-19 increased exponentially during March 1-31, 2020; the numbers fell during April 1-14, after lockdown was imposed on March 17. The shape of the curve of active critical COVID-19 mirrored that of all active cases. By April 14, among the 617 pregnant women with COVID-19, 93 women (15.1 %; 95 %CI 12.3-18.1) had required oxygen therapy and 35 others (5.7 %; 95 %CI 4.0-7.8) had had a critical form of COVID-19. The severity of the disease was associated with age older than 35 years and obesity, as well as preexisting diabetes, previous preeclampsia, and gestational hypertension or preeclampsia. One woman with critical COVID-19 died (0.2 %; 95 %CI 0-0.9). Among the women who gave birth, rates of preterm birth in women with non-severe, oxygen-requiring, and critical COVID-19 were 13/123 (10.6 %), 14/29 (48.3 %), and 23/29 (79.3 %) before 37 weeks and 3/123 (2.4 %), 4/29 (13.8 %), and 14/29 (48.3 %) before 32 weeks, respectively. One neonate (0.5 %; 95 %CI 0.01-2.9) in the critical group died from prematurity. CONCLUSION: COVID-19 can be responsible for significant rates of severe acute, potentially deadly, respiratory distress syndromes. The most vulnerable pregnant women, those with comorbidities, may benefit particularly from prevention measures such as a lockdown.
