Identifying the key events in a document is critical to holistically understanding its important information. Although measuring the salience of events is highly contextual, most previous work has used a limited representation of events that omits essential information. In this work, we propose a highly contextual model of event salience that uses a rich representation of events, incorporates document-level information and allows for interactions between latent event encodings. Our experimental results on an event salience dataset (Liu et al., 2018) demonstrate that our model improves over previous work by an absolute 2-4% on standard metrics, establishing a new state-of-the-art performance for the task. We also propose a new evaluation metric which addresses flaws in previous evaluation methodologies. Finally, we discuss the importance of salient event detection for the downstream task of summarization. 1
Leiomyomas are the most common pelvic tumors, cervical uterine myoma being rare of all uterine fibroids with an incidence of 0.6% of all fibroids. Based on their location, cervical myomas can be classified as extra cervical (sub-serosal myoma) and intracervical. Cervical fibroids can further be anterior, posterior, lateral, and central depending on their position. The surgical treatment of cervical leiomyomas poses more difficulty; due to the risk of intraoperative Hemorrhage and the potential injuries because of contiguity and dislocation of adjacent organs. We present the case of a 46-year-old female, presenting with pain abdomen and abdominal distension. Contrast enhanced-magnetic resonance imaging showed a giant cervical myoma. Enucleation of myoma was done followed by total abdominal hysterectomy with bilateral salpingectomy. Injury to the ureter can be avoided with preoperative cystoscopy-guided bilateral ureteral stenting, intraoperative tracing of the ureter before applying a clamp, and dissection inside the fibroid capsule.
Abnormal Low Lying Implantation of Ectopic Pregnancy (LLIEP) may occur in cervix, cervico isthmic region or caesarean scar. Cervicoisthmic pregnancy remains the rarest form of LLIEP, a life threatening cause of maternal morbidity and mortality with an incidence of 1 in every 2400 to 4500 pregnancies. In isthmic implantation, the gestational sac is located more cranially and between the cervix distally and the decidualised functional endometrium cranially. Transvaginal Ultrasound (TVS), Colour Doppler and Magnetic Resonance Imaging (MRI) remain gold standard modalities for early diagnosis. Ultrasonography depicts bulging lower uterine segment with a normal cervical length and consistency. Here, the author reports a rare case of ruptured isthmic pregnancy with 20 weeks intrauterine foetus death lying in left broad ligament in a 33-year-old unbooked G3P2L2 with gestation of 31 weeks presenting in emergency. Ultrasonography depicted intrauterine foetus death with foetus lying in lower segment of uterus. Lower section caesarean section for failed induction confirmed hour glass uterus with empty upper uterine segment and bulging, distended, couvelaire lower uterine segment and left lateral rupture at cervicoisthmic junction. Dead 20 weeks foetus lying in leaves of left broad ligament. Peripartum hysterectomy was done as a life saving procedure. Cervicoisthmic pregnancy is rarest form of LLIEP and diagnosis may result in rupture with need of peripartum hysterectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
