Endometriosis-related infertility: severe pain symptoms do not impact assisted reproductive technology outcomes.

STUDY QUESTION: Do severe endometriosis-related painful symptoms impact ART live birth rates? SUMMARY ANSWER: Severe pain symptoms are not associated with reduced ART live birth rates in endometriosis patients. WHAT IS KNOWN ALREADY: ART is currently recognized as one of the main therapeutic options to manage endometriosis-related infertility. Presently, no data exist in the literature regarding the association between the core symptom of the disease, e.g. pain and ART reproductive outcomes. STUDY DESIGN, SIZE, DURATION: Observational cohort study of 354 endometriosis patients, who underwent ART at a tertiary care university hospital, between October 2014 and October 2021. Diagnosis of endometriosis was based on published imaging criteria using transvaginal sonography and magnetic resonance imaging, and histologically confirmed in women who had a previous history of endometriosis surgery (n = 127, 35.9%). PARTICIPANTS/MATERIALS, SETTING, METHODS: The intensity of painful symptoms related to dysmenorrhea (DM), dyspareunia (DP), noncyclic chronic pelvic pain, gastrointestinal (GI) pain, or lower urinary tract pain was evaluated using a 10-point visual analog scale (VAS), before ART. Severe pain was defined as having a VAS of 7 or higher for at least one symptom. The main outcome measure was the cumulative live birth rate (CLBR) per patient. We analyzed the impact of endometriosis-related painful symptoms on ART live births using univariable and multivariate analysis. MAIN RESULTS AND THE ROLE OF CHANCE: Three hundred and fifty-four endometriosis patients underwent 711 ART cycles. The mean age of the population was 33.8 ± 3.7 years, and the mean duration of infertility was 3.6 ± 2.1 years. The distribution of the endometriosis phenotypes was 3.1% superficial endometriosis, 8.2% ovarian endometrioma, and 88.7% deep infiltrating endometriosis. The mean VAS scores for DM, DP, and GI pain symptoms were 6.6 ± 2.7, 3.4 ± 3.1, and 3.1 ± 3.6, respectively. Two hundred and forty-two patients (68.4%) had severe pain symptoms. The CLBR per patient was 63.8% (226/354). Neither the mean VAS scores for the various painful symptoms nor the proportion of patients displaying severe pain differed significantly between patients who had a live birth and those who had not, based on univariate and multivariate analyses (P = 0.229). The only significant factors associated with negative ART live births were age >35 years (P < 0.001) and anti-Müllerian hormone levels <1.2 ng/ml (P < 0.001). LIMITATIONS, REASONS FOR CAUTION: The diagnosis of endometriosis was based on imaging rather than surgery. This limitation is, however, inherent to the design of most studies on endometriosis patients reverting to ART first. WIDER IMPLICATIONS OF THE FINDINGS: Rather than considering a single argument such as pain, the decision-making process for choosing between ART and surgery in infertile endometriosis patients should be based on a multitude of aspects, including the patient's choice, the associated infertility factors, the endometriosis phenotypes, and the efficiency of medical therapies in regard to pain symptoms, through an individualized approach guided by a multidisciplinary team of experts.

Presence of adenomyosis at MRI reduces live birth rates in ART cycles for endometriosis.

STUDY QUESTION: What is the impact of adenomyosis on the live birth rate (LBR) in women affected by endometriosis women undergoing ART? SUMMARY ANSWER: For women undergoing ART, the presence of adenomyosis at MRI, especially T2 high-signal intensity spots within the myometrium, has a negative impact on the LBR. WHAT IS KNOWN ALREADY: Adenomyosis is a common gynecological disease. The development of imaging techniques for the diagnosis has led to several adenomyosis phenotypes being described, and fertility issues appear to vary according to the characteristics of the lesions. What makes assessment of the impact of adenomyosis on fertility issues even more difficult is its frequent association with endometriosis, which is another known risk factor of infertility. Although data suggest that adenomyosis may worsen the ART prognosis, there is no clear consensus regarding the impact of adenomyosis on ART outcomes in women affected by endometriosis. STUDY DESIGN, SIZE, DURATION: This was an observational study that included phenotyped patients with endometriosis, aged between 18 and 42 years, who underwent IVF/ICSI treatment in a tertiary care center between June 2015 and July 2018. Only women who had undergone a pelvic MRI during the pre-therapeutic ART workup were retained for this study. The MRI data were interpreted by radiologists who had expertise in gynecological MRI. PARTICIPANTS/MATERIALS, SETTING, METHODS: A continuous series of 202 women affected by endometriosis was included. The women were monitored until four ART cycles had been completed, until delivery, or until discontinuation of treatment before the completion of four cycles. The primary outcome was the delivery of at least one live infant after up to four IVF/ICSI cycles. The patient and the MRI characteristics were compared between the women who achieved a live birth versus those who did not. MAIN RESULTS AND THE ROLE OF CHANCE: The patients' mean age was 32.5 ± 3.7 years. Deep infiltrating endometriosis was present in 90.1% (182/202) of the included population. Adenomyosis (lesions of the internal and/or the external myometrium) was found in 71.8% (145/202) of the included women. The cumulative LBR was 57.4% (116/202). The women who gave birth were significantly younger (32.0 ± 3.3 versus 33.3 ± 4.1, P = 0.026) and had significantly better ovarian reserve parameters (anti-Müllerian hormone levels, antral follicle count) than those who did not. The presence of adenomyosis, irrespective of the phenotype (76/116 (65.5%) versus 69/86 (80.2%), respectively, P = 0.022) and the presence of T2 high-signal intensity myometrial spots (27/116 (23.3%) and 37/86 (43.0%), respectively, P = 0.003) was significantly less frequent in the group of women who gave birth versus those who did not. After multivariate analysis, the presence of adenomyosis (odds ratio (OR): 0.48, 95% CI (0.29-0.99), P = 0.048) and the presence of T2 high-signal intensity myometrial spots (OR: 0.43, 95% CI (0.22-0.86), P = 0.018) were independently found to be associated with a decrease in the cumulative chance of live birth. LIMITATIONS, REASONS FOR CAUTION: The inclusion of patients from a referral center specialized in the management of women affected by endometriosis could constitute a selection bias, as these women may have had particularly severe forms of adenomyosis and/or endometriosis. A sensitive issue is that there is no consensual classification of adenomyosis and several lesions of adenomyosis can co-exist. Therefore, a comparison of fertility outcomes between women with and without adenomyosis is difficult to perform in practice. WIDER IMPLICATIONS OF THE FINDINGS: In women exhibiting endometriosis, the practitioner should perform an appropriate imaging workup to search for adenomyosis, identify prognostic factors, and personalize the patient management strategy in the setting of ART. STUDY FUNDING/COMPETING INTEREST(S): No funding was obtained and there were no conflicts of interest. TRIAL REGISTRATION NUMBER: N/A.

Adenomyosis of the inner and outer myometrium are associated with different clinical profiles.

STUDY QUESTION: Do adenomyosis phenotypes such as external or internal adenomyosis, as diagnosed by MRI, have the same clinical characteristics? SUMMARY ANSWER: External adenomyosis was found more often in young and nulliparous women and was associated with deep infiltrating endometriosis, whereas, in contrast, internal adenomyosis was more often associated with heavy menstrual bleeding (HMB) but no differences were noted in terms of pain symptoms. WHAT IS KNOWN ALREADY: Adenomyosis is characterized by the presence of endometrial glands and stroma deep within the myometrium, giving rise to dysmenorrhea, pelvic pain and menorrhagia. Various forms have been described, including adenomyosis of the outer myometrium (external adenomyosis), which corresponds to lesions separated from the junctional zone (JZ), and adenomyosis of the inner myometrium (internal adenomyosis), which is mostly characterized by endometrial implants scattered throughout the myometrium and enlargement of the JZ. Although the pathogenesis of adenomyosis is not clearly understood, several lines of evidence suggest that these two phenotypes could have distinct origins. The clinical presentation of different forms of adenomyosis in patients warrants further investigation. STUDY DESIGN, SIZE, DURATION: This was an observational study that used data collected prospectively in non-pregnant patients aged between 18 and 42 years who had undergone surgical exploration for benign gynecological conditions at our institution between May 2005 and May 2018. Only women with a pelvic MRI performed by a senior radiologist during the preoperative work-up were retained for this study. For each patient, a standardized questionnaire was completed during a face-to-face interview conducted by the surgeon in the month preceding the surgery. The women's histories (notably their age, gravidity, history of surgery and associated endometriosis), as well as clinical symptoms such as the pain intensity, presence of menorrhagia and infertility, were noted. PARTICIPANTS/MATERIALS, SETTING, METHODS: A pelvic MRI was performed in 496 women operated at our center for a benign gynecological disease who had provided signed informed consent. Of these, 248 women had a radiological diagnosis of adenomyosis. Based on the MRI findings, the women were diagnosed as having external and/or internal adenomyosis. The women were allocated to two groups according to the adenomyosis phenotype (only external adenomyosis vs only internal adenomyosis). Women exhibiting an association of both adenomyosis forms were analyzed separately. MAIN RESULTS AND THE ROLE OF CHANCE: In all, following the MRI findings, 109 women (44.0%) exhibited only external adenomyosis, while 78 (31.5%) had only internal adenomyosis. The women with external adenomyosis were significantly younger (mean ± SD; 31.9 ± 4.6 vs 33.8 ± 5.2 years; P = 0.006), more often nulligravid (P ≤ 0.001) and more likely to exhibit an associated endometriosis (P < 0.001) compared to the women in the internal adenomyosis group. Moreover, the women exhibiting internal adenomyosis significantly more often had a history of previous uterine surgery (P = 0.002) and HMB (62 (80%) vs 58 (53.2%), P < 0.001) compared to the women with external adenomyosis. No differences in the pain scores (i.e. dysmenorrhea, non-cyclic pelvic pain and dyspareunia) were observed between the two groups. LIMITATIONS, REASONS FOR CAUTION: The exclusive inclusion of surgical patients could constitute a possible selection bias, as the women referred to our center may have suffered from particularly severe clinical symptoms. WIDER IMPLICATIONS OF THE FINDINGS: Further studies are needed to explore the pathogenesis by which these types of adenomyosis occur. This could help with the development of new treatment strategies specific for each entity. STUDY FUNDING/COMPETING INTEREST(S): none. TRIAL REGISTRATION NUMBER: N/A.

Five simultaneous artificial intelligence data challenges on ultrasound, CT, and MRI.

PURPOSE: The goal of this data challenge was to create a structured dynamic with the following objectives: (1) teach radiologists the new rules of General Data Protection Regulation (GDPR), while building a large multicentric prospective database of ultrasound, computed tomography (CT) and MRI patient images; (2) build a network including radiologists, researchers, start-ups, large companies, and students from engineering schools, and; (3) provide all French stakeholders working together during 5 data challenges with a secured framework, offering a realistic picture of the benefits and concerns in October 2018. MATERIALS AND METHODS: Relevant clinical questions were chosen by the Société Francaise de Radiologie. The challenge was designed to respect all French ethical and data protection constraints. Multidisciplinary teams with at least one radiologist, one engineering student, and a company and/or research lab were gathered using different networks, and clinical databases were created accordingly. RESULTS: Five challenges were launched: detection of meniscal tears on MRI, segmentation of renal cortex on CT, detection and characterization of liver lesions on ultrasound, detection of breast lesions on MRI, and characterization of thyroid cartilage lesions on CT. A total of 5,170 images within 4 months were provided for the challenge by 46 radiology services. Twenty-six multidisciplinary teams with 181 contestants worked for one month on the challenges. Three challenges, meniscal tears, renal cortex, and liver lesions, resulted in an accuracy>90%. The fourth challenge (breast) reached 82% and the lastone (thyroid) 70%. CONCLUSION: Theses five challenges were able to gather a large community of radiologists, engineers, researchers, and companies in a very short period of time. The accurate results of three of the five modalities suggest that artificial intelligence is a promising tool in these radiology modalities.

[Disability and epilepsy]. / Handicap et épilepsie.

The purpose of this article is to familiarize radiologists with the different aspects of severe drug resistant epilepsy. These result in three levels of disability: the disease itself (seizures and their impact, underlying cause), social impact (restrictions, safety and precautions, education, activities of daily life) and issues related to the medical treatment (long term medication intake, side effects, complications). First, clinical and EEG diagnosis will be reviewed to move on to MRI with attention to technical and protocol considerations followed by the imaging features of specific entities causing severe drug resistant epilepsy: migration and gyration disorders, Rasmussen's encephalitis, Sturge Weber disease and post-ischemic sequelae. Finally, current data and the imaging features of hemispherotomy, a radical treatment for epilepsy, will be presented.

[CT and MR brain imaging following hemispherotomy]. / Imagerie scanner et IRM de l'encéphale après hémisphérotomie.

PURPOSE: The aim of the study was to define the usual and pathological modifications arising in the brain following hemispherotomy for intractable epilepsy in children. METHODS: Preoperative MRI and postoperative imaging scans (CT in the first week, MRI at 3 months and 1 year after surgery) were reviewed in a series of 52 patients, average age 8 years and 7 months, with intractable epilepsy due to dysplasia, Rasmussen's encephalitis, ischemic lesions and/or Sturge-Weber disease. The posterior fossa, brain parenchyma, ventricles and subdural space were also analyzed. RESULTS: Hemispheric scarring was a typical finding on CT and MRI as a consequence of the surgical procedure. Also frequently seen were small subdural effusions, bleeding along the surgical scar on early CT, and chronic subdural effusions with no mass effect on mid-term and late MRI scans. Other features - such as large subdural effusions that required external shunts and hydrocephalus - were rare, but severe, and considered to be postoperative complications. In contrast to the complications associated with other surgical techniques such as hemispherectomy, infection, extensive edema or hemosiderosis were never found in our series. CONCLUSION: Hemispherotomy is a surgical technique performed to treat intractable epilepsy. Our findings will help to identify the typical morphology of postsurgical scars, and to differentiate the usual features and complications seen in the postoperative period on CT and MRI brain scans.
