BACKGROUND: Congenital midfacial hypoplasia often requires intensive treatments and is a typical condition for the Binder phenotype and syndromic craniosynostosis. The growth trait of the midfacial skeleton during the early fetal period has been assumed to be critical for such an anomaly. However, previous embryological studies using 2-dimensional analyses and specimens during the late fetal period have not been sufficient to reveal it. OBJECTIVE: To understand the morphogenesis of the midfacial skeleton in the early fetal period via 3-dimensional quantification of the growth trait and investigation of the developmental association between the growth centers and midface...

Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disorder caused by antibody to aquaporin-4 (AQP4). NMOSD can infrequently present as a complication of posterior reversible encephalopathy syndrome (PRES). Moreover, few cases of NMOSD patients with brain hemorrhage have been reported. We report a rare case of PRES together with NMOSD recurrence, subsequent to pontine hemorrhage after intravenous methylprednisolone (IVMP) therapy. A 51-year-old Japanese woman, with a history of hypertension and dyslipidemia, and recurrent episodes of left visual acuity disorder related to AQP4-positive NMOSD, developed blindness in the left eye...

Idiopathic Parkinson's disease (PD) is a progressive neurological condition which affects the dopamine transporters in the substantia nigra of the brain. Currently, over ten million people are living with this disease world-wide, with thousands of newly diagnosed and undiagnosed cases added every year. The disease is difficult to differentiate from other similar disorders, as symptoms widely vary and can mimic other conditions. Classic Parkinson's disease symptoms may look similar to essential tremor and other parkinsonian syndromes...

Eye tracking is an effective tool for identifying behavioural aspects of unilateral spatial neglect (USN), which is a common neurological syndrome that develops after a right hemisphere lesion. Here, we attempted to elucidate how the neglect symptom affects the symmetry of the gaze pattern, by performing an analysis of gaze distribution during the free viewing of a pair of horizontally flipped images. Based on their Behavioural Inattention Test (BIT) scores, 41 patients with right-hemisphere damage were classified into those with USN (n = 27) and those without USN (right hemisphere damaged - RHD; n = 14)...

OBJECTIVES: Positron emission tomography with computed tomography (PET-CT) with 18 F-FDG may be useful in patients with primary Sjögren's syndrome (pSS), but its usefulness for the diagnosis of lymphoma is unclear since it may reveal abnormalities due to systemic manifestations. We aimed to compare 18 F-FDG PET-CT between pSS patients with or without lymphoma, to identify patterns associated with lymphoma. METHODS: Retrospective study conducted in 2 centers including pSS patients (ACR/EULAR 2016 criteria) who undergone PET-CT...

Historically, visual acuity has been the benchmark for visual function. It is used to measure therapeutic outcomes for vision-related services, products and interventions. Quantitative measurement of suboptimal visual acuity can potentially be corrected optically with proper refraction in some cases, but in many cases of reduced vision there is something else more serious that can potentially impact other aspects of visual function such as contrast sensitivity, color discrimination, peripheral field of view and higher-order visual processing...

PURPOSE: Systematic examination of increased intracranial pressure (ICP) is important during the follow-up period after surgical repair of syndromic craniosynostosis. In these patients, postoperative progress can be unclear due to the involvement of multiple sutures and the high incidence of relapse due to the progressive nature of the disease and to genetic variability. In this study, we investigated the clinical manifestations of increased ICP in syndromic craniosynostosis patients before and after surgery...

Disorders of the inner-ear balance organs can be grouped by their manner of presentation into acute, episodic, or chronic vestibular syndromes. A sudden unilateral vestibular injury produces severe vertigo, nausea, and imbalance lasting days, known as the acute vestibular syndrome (AVS). A bedside head impulse and oculomotor examination helps separate vestibular neuritis, the more common and innocuous cause of AVS, from stroke. Benign positional vertigo, a common cause of episodic positional vertigo, occurs when otoconia overlying the otolith membrane falls into the semicircular canals, producing brief spells of spinning vertigo triggered by head movement...

Magnetic resonance imaging (MRI), single photon emission computed tomography (SPECT) and positron emission tomography (PET) are the main instruments for neuroimaging investigation of patients with chronic ataxia. MRI has a predominant diagnostic role in the single patient, based on the visual detection of three patterns of atrophy, namely, spinal atrophy, cortical cerebellar atrophy and olivopontocerebellar atrophy, which correlate with the aetiologies of inherited or sporadic ataxia. In fact spinal atrophy is observed in Friedreich ataxia, cortical cerebellar atrophy in Ataxia Telangectasia, gluten ataxia and Sporadic Adult Onset Ataxia and olivopontocerebellar atrophy in Multiple System Atrophy cerebellar type...

BACKGROUND: Bow hunter syndrome describes a mechanical compression of the vertebral artery on head rotation leading to reversible symptomatic vertebrobasilar insufficiency. Patients are commonly presenting with syncope, vertigo, dizziness, and visual disturbances. These symptoms usually resolve when the head is turned back into neutral position. Treatment options involve surgical decompression with or without fusion, bypass surgery, or endovascular intervention. CASE DESCRIPTION: We report about a 49-year-old female who presented with vague neck pain and severe vertigo, nausea, and near syncope when her head turned up and right...

J Collot, N Bletard, A Lamproye
Rarely encountered in the Western countries, membranous occlusion of the inferior vena cava results from a fibrous thickening of the intima and is commonly located at the orifices of the hepatic veins. To date, two etiopathogenic hypotheses have been formulated: the first, dealing with the embryological aspect, the second, arguing for a thrombotic origin. Nevertheless, several studies are still underway to understand the exact physiopathological mechanism of this obstruction. Among these studies, some suspect the predisposing role of anatomical and infectious factors...

Brain-computer interfaces (BCIs) enable communication with others and allow machines or computers to be controlled in the absence of motor activity. Clinical studies evaluating neural prostheses in amyotrophic lateral sclerosis (ALS) patients have been performed; however, to date, no study has reported that ALS patients who progressed from locked-in syndrome (LIS), which has very limited voluntary movement, to a completely locked-in state (CLIS), characterized by complete loss of voluntary movements, were able to continue controlling neural prostheses...
