AIMS: To observe the corrective effects of maternal extreme flexure and hip abduction combined with contralateral side-lying on persistent foetal occipito-posterior position. BACKGROUND: Digital rotation and other methods are used for correction of a persistent foetal occipito-posterior position. However, digital rotation readily causes damage to mother and foetus, and the correction rates of other methods are low. DESIGN: In this observational study, pregnant women were randomly divided into 2 groups according to different postures and their outcomes were compared...

Obstetric anal sphincter injury (OASI) is the most common cause of anal incontinence and ano-rectal symptoms in women1 . Reported rates of anal incontinence following primary repair of OASI range between 15-61%, with a mean of 39%2, 3 . Other possible complications of OASI include perineal pain, dyspareunia, and less commonly, abscess formation, wound breakdown, and rectovaginal fistulae. Symptom onset may occur immediately, several years postpartum, or only late in life when aging of tissues adds to the delivery insult...

BACKGROUND: Fetal occiput posterior positions are associated with poorer maternal outcomes than occiput anterior positions. Although methods that include instrumental and manual rotation can be used at the end of labor to promote the rotation of the fetal head, various maternal postures may also be performed from the beginning of labor in occiput posterior position. Such postures might facilitate flexion of the fetal head and favor its rotation into an occiput anterior position. OBJECTIVE: The purpose of this study was to determine whether a lateral asymmetric decubitus posture facilitates the rotation of fetal occiput posterior into occiput anterior positions...

BACKGROUND: Previous studies found that the facet joint of the C1 vertebra were removed (C1 facetectomy) before extirpation from the extramedullary tumor in craniocervical junction, leading to postoperative upper cervical instability or deformity. Occipito-cervical fusion (OCF) is a demanding and morbid surgical procedure, which can be used in such patients. This study is to analyze the clinical manifestation and surgical outcome of patients with craniocervical extramedullary tumor undergoing an extirpation of spinal tumors and OCF by one-stage posterior approach...

OBJECTIVE: To estimate the association of fetal head position prior to vacuum extraction (VE) and pregnancy outcome. STUDY DESIGN: A retrospective cohort study of singleton pregnancies who underwent VE. Pregnancy outcome of occipito-anterior (OA) position of the fetal head was compared to those with occipito-posterior (OP) position. RESULTS: Amongst overall 12,063 women undergoing trial of labor, there were 1118 (9.2%) VE deliveries. Of them, 871 (77...

Neuroimaging studies have identified a network of regions in the human ventral occipito-temporal cortex (VOTC) sensitive to faces. Using intra-cerebral electrophysiological recordings, we compared the relative responsivity of the different regions to face-structure using a periodic visual stimulation paradigm. Recordings were made in 17 epileptic patients implanted with linear-array depth-electrodes (>1000 contacts in the VOTC). In Experiment 1, we presented sequences of phase-scrambled and intact face stimuli (equalised for low-level image properties) alternating at a fixed frequency of 3Hz (6 images/s) while patients completed an orthogonal task...

Humans are extremely rapid at categorizing visual inputs, an ability which relies on occipito-temporal brain processes. Functional neuroimaging studies have identified the spatial organization of neural responses in these regions to ecologically-relevant categories such as faces, bodyparts or houses. However, much less is known about the spatio-temporal dynamics of these category-selective responses at the system level of organization. Here we investigate this issue by recording scalp electroencephalogram (EEG) during fast periodic visual stimulation (FPVS) with natural images (Rossion et al...

To date, the neural mechanisms of feature information integration across saccades, also known as trans-saccadic integration (TSI), of low-level object features are relatively unknown. Using fMRI adaptation (fMRIa), we found that the right inferior parietal lobule (IPL; specifically, SMG) and extrastriate cortex (putative V4) are sensitive to stimulus orientation in a space-fixed reference frame (Dunkley & Crawford, Society for Neuroscience Abstracts, 2012). To identify the neural mechanisms of underlying TSI in multiple reference frames, we employed fMRIa to probe three spatial conditions: 1) Space-fixed, 2) Retina-fixed and 3) Frame-independent (neither Space-fixed, nor Retina-fixed)...

Over the last two decades neurophysiological and neuroimaging studies have identified a network of brain regions in occipito-temporal, parietal, and frontal cortex that are involved in visual processing of actions. What remains unclear are the neural computations and representational properties in each area. In this study, we investigated the representational content of human brain areas in the action observation network using fMRI and representational similarity analysis. Observers were shown video clips of 8 different actions performed by 3 different agents (actors) during fMRI scanning...

Face perception involves a large set of regions distributed along the ventral temporal cortex and thus represents an interesting model to help understanding how visual information is processed along the ventral visual pathway. Here we shed light on the functional organization of this cortical network by recording focal intracerebral electroencephalogram in 20 epileptic patients implanted with depth electrodes. We objectively defined and quantified face-selective responses in the frequency domain by means of fast periodic visual stimulation with natural images (Rossion et al...

The ability to process and identify visual words requires efficient orthographic processing of print, consisting of letters in alphabetic languages or characters in Chinese. The N170 is a robust neural marker for orthographic processes. Both genetic and environmental factors, such as home literacy, have been shown to influence orthographic processing at the behavioral level, but their relative contributions and interactions are not well understood. The present study aimed to reveal possible gene-by-environment interactions on orthographic processing at the behavioral and neural level in a normal children sample...

Visual analysis of real-life scenes starts with the parallel extraction of different visual elementary features at different spatial frequencies. The global shape of the scene is mainly contained in low spatial frequencies (LSF), and the edges and borders of objects are mainly contained in high spatial frequencies (HSF). The present fMRI study investigates the effect of age on the spatial frequency processing in scenes. Young and elderly participants performed a categorization task (indoor vs. outdoor) on LSF and HSF scenes...

BACKGROUND: Body dysmorphic disorder (BDD) and anorexia nervosa (AN) are both characterized by distorted perception of appearance. Previous studies in BDD suggest abnormalities in visual processing of own and others' faces, but no study has examined visual processing of faces in AN, nor directly compared the two disorders in this respect. METHOD: We collected functional magnetic resonance imaging data on 60 individuals of equivalent age and gender in each of three groups--20 BDD, 20 weight-restored AN, and 20 healthy controls (HC)--while they viewed images of others' faces that contained only high or low spatial frequency information (HSF or LSF)...

The neural correlates of visualization underlying word comprehension were examined in preschool children. On each trial, a concrete or abstract word was delivered binaurally (part 1: post-auditory visualization), followed by a four-picture array (a target plus three distractors; part 2: matching visualization). Children were to select the picture matching the word they heard in part 1. Event-related potentials (ERPs) locked to each stimulus presentation and task interval were averaged over sets of trials of increasing word abstractness...

We report an uncommon case of posterior circulation stroke in a young patient due to occlusion of posterior cerebral artery with reducible atlantoaxial dislocation (AAD). Plain dynamic radiography showed reducible AAD and intra-arterial digital subtraction angiography demonstrated occlusion of left posterior cerebral artery. Patient underwent stabilization of craniovertebral junction by occipito cervical fixation using occipit-C2/C3 lateral mass screws and rod fixation and has since experienced no recurrent symptoms...
