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...

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...

Bony malformations of the orbit and alterations to the soft tissue in Apert syndrome contribute to ophthalmic dysfunction. Recognised structural malformation of the sphenoid and ethmoid sinuses, together with corresponding deformities in the anterior and middle cranial base, are characteristic. Our aim was to explore the underlying structural components of disfigurement and the consequent development of the orbit in patients with Apert syndrome over time by studying 18 preoperative computed tomographic (CT) scans of affected patients and 36 scans from controls...

Bronchial anthracofibrosis (BAF), caused by long-standing exposure to biomass fuel smoke, has emerged as a distinct pulmonary disease. It is usually seen in elderly females who have worked long hours in poorly ventilated kitchen full of smoke due to incomplete combustion of biomass fuel. The diagnosis is confirmed on bronchoscopic visualization of bluish-black anthracotic pigmentation along with narrowing/distortion of the affected bronchus. BAF has been associated with clinical conditions such as pulmonary tuberculosis, chronic obstructive pulmonary disease, pneumonia, and malignancy...

In daily interactions, our sensorimotor system accounts for spatial and temporal discrepancies between the senses. Functional lateralization between hemispheres causes differences in attention and in the control of action across the left and right workspaces. In addition, differences in transmission delays between modalities affect movement control and internal representations. Studies on motor impairments such as hemispatial neglect syndrome suggested a link between lateral spatial biases and temporal processing...
