A diagnostic dilemma of an 18-week cervical ectopic pregnancy: A case report.

Introduction: Cervical ectopic pregnancy (CEP) is characterised by the implantation of trophoblastic tissue within the cervical canal and is associated with a significant risk of maternal morbidity and mortality. This case report addresses a second-trimester CEP with unusual sonographic features suspicious of placenta accreta spectrum (PAS), which was successfully managed with an abdominal hysterectomy.

Case Presentation: A 27-year-old woman, G6P2, presented to the labour ward of a rural hospital at 18 weeks of gestation with premature rupture of membranes.

The risk of adverse maternal outcomes in cases of placenta praevia in an Australian population between 2007 and 2017.

Background: Placenta praevia is characterised by an inferior placental margin that overlies or falls within 20 mm of the endocervical os. It remains a common cause of antepartum haemorrhage and is associated with adverse maternal and neonatal outcomes.

Aims: We aimed to determine the association between antepartum and postpartum haemorrhage and adverse outcomes in cases of placenta praevia.

The monaural spectral cues identified by a reverse correlation analysis of free-field auditory localization data.

The outer-ear's location-dependent pattern of spectral filtering generates cues used to determine a sound source's elevation as well as front-back location. The authors aim to identify these features using a reverse correlation analysis (RCA), combining free-field localization behaviour with the associated head-related transfer functions' (HRTFs) magnitude spectrum from a sample of 73 participants. Localization responses were collected before and immediately after introducing a pair of outer-ear inserts which modified the listener's HRTFs to varying extent.

The management of severe pre-eclampsia and HELLP syndrome in a twin pregnancy with a known morbidly adherent placenta: A case report.

Introduction: Morbidly adherent placenta (MAP) is a rare obstetric complication, especially in cases of multiple gestation. We present a case of MAP complicating a dichorionic diamniotic (DCDA) twin pregnancy requiring delivery by emergency cesarean hysterectomy at 30 + 2 weeks of gestation.

Case Presentation: A 36-year-old woman, G3P2, with a DCDA twin pregnancy and known MAP presented to the labour ward at 30 + 2 weeks of gestation with evidence of pre-eclampsia and fulminating HELLP syndrome.

The Generalization of Auditory Accommodation to Altered Spectral Cues.

The capacity of healthy adult listeners to accommodate to altered spectral cues to the source locations of broadband sounds has now been well documented. In recent years we have demonstrated that the degree and speed of accommodation are improved by using an integrated sensory-motor training protocol under anechoic conditions. Here we demonstrate that the learning which underpins the localization performance gains during the accommodation process using anechoic broadband training stimuli generalize to environmentally relevant scenarios.

Accommodating to new ears: the effects of sensory and sensory-motor feedback.

Changing the shape of the outer ear using small in-ear molds degrades sound localization performance consistent with the distortion of monaural spectral cues to location. It has been shown recently that adult listeners re-calibrate to these new spectral cues for locations both inside and outside the visual field. This raises the question as to the teacher signal for this remarkable functional plasticity.
