Although there have been reports of carotid artery pseudoaneurysm formation after adenoidectomy and/or tonsillectomy secondary to iatrogenic injury, there are no case reports of successful endovascular reconstruction of the injured artery in the pediatric population. In most pediatric cases, the internal carotid artery (ICA) is sacrificed. The authors report on a 6-year-old girl who presented with odynophagia, left-sided Horner's syndrome, hematemesis, and severe anemia 6 months after a tonsillectomy. On examination she was found to have a pulsatile mass along the left posterior lateral oropharynx, and imaging demonstrated a dissection of the extracranial left ICA and an associated pseudoaneurysm...

Internal carotid artery (ICA) dissections with associated stroke are rare events in infants. The usual pathomechanisms include direct trauma to the artery, blunt intraoral trauma, or child abuse. We describe the case of a 4-month-old male patient with ICA dissection and associated middle cerebral artery territory infarction associated with hyperextension/hyperrotation after a minor head injury. Upon treatment with anticoagulants, the patient showed significant improvement of the left-sided hemiparesis. Hemorrhagic transformation that presented shortly after middle cerebral artery infarction did not further increase under heparin treatment and prevented further embolism...

INTRODUCTION: Infections involving methicillin-resistant Staphylococcus aureus (MRSA) remain a serious threat to hospitalized patients worldwide. MRSA is characterized by recalcitrance to antimicrobial therapy, which is a function not only of widespread antimicrobial resistance, but also the capacity to form biofilms. The present study evaluated the presence of genes encoding adhesion factors and the biofilm-forming capacity in MRSA. METHODOLOGY: In this study, 53 isolates of MRSA, recovered from December 2010 to May 2014 in a mother and child hospital, CHU Mohamed VI in Marrakech, Morocco, were screened for the presence of bap and ica genes associated with biofilm formation, and for bbp, cna, ebpS, eno, fib, fnbA, fnbB, clfA, and clfB genes that encode microbial surface components recognizing adhesive matrix molecules (MSCRAMMs)...

Persistent primitive hypoglossal artery (PPHA) is a rare embryonic carotid vertebrobasilar artery anastomosis. Hypoglossal artery arises from the internal carotid artery (ICA) between the C1 and C2 vertebral levels and traverses through the hypoglossal canal to join the vertebro-basilar system. We present a rare case of an anomalous right sided PPHA as a sole supply to posterior circulation of brain with absent/hypoplastic bilateral vertebral arteries in a two year child who had presented with acute left sided haemiplegia...

We describe a rare case of carotid pseudoaneurysm secondary to a retropharyngeal abscess, treated with coil embolization in a 2-year-old boy. The patient presented to an emergency department with symptoms suggesting meningitis but was subsequently diagnosed with streptococcal pharyngitis. He was discharged home on oral antibiotics after a short hospitalization. He returned to the emergency department two weeks later with limited neck motion and pain. Neck CT demonstrated a retropharyngeal abscess with a large left cervical internal carotid artery (ICA) pseudoaneurysm...

This report describes a 9-year-old boy with an internal carotid artery (ICA) injury caused by a fall with the blunt edge of a toothbrush held in the mouth. The initial injury appeared trivial, but 2 weeks later, generalized convulsion and left hemiparesis occurred. Magnetic resonance imaging and magnetic resonance angiography revealed an infarction of the right striatum, right ICA occlusion, and stenosis of the right middle cerebral artery, which were caused by the dissection or intimal damage of the ICA due to the blunt trauma...

We report a rare case of spontaneous extracranial cervical internal carotid artery (ICA) pseudoaneurysm in a female child aged 3 years who presented with a swelling in the neck which had bled following an attempted incision as it had been thought to be an abscess. A CT angiogram and an MR angiogram were not very conclusive to diagnose the exact site of origin and the morphology of the aneurysm. Digital subtraction angiography revealed a dissecting pseudoaneurysm of the right extracranial cervical ICA. The right ICA was ending as a pseudosac, and the right cerebral circulation was filling up through the right posterior cerebral artery...

The method of independent components within the range of 3-13 Hz was used for the analysis of EEG of the children with psychic abnormalities of perinatal origin. The research was undertaken while children were keeping awake with open eyes. In cases of harder developmental delay it was revealed a significant rise of θ-range power spectrum in frontal-temporal cortex areas of left hemisphere and temporal areas of right hemisphere. This fact make it possible to regard these areas as hypothetic sources of slow activity and a damage/immaturity marker of frontal-thalamic area and the temporal areas, responsible for auditory analysis and verbal synthesis, audio & visual data integration...

Schimke immuno-osseous dysplasia (SIOD) is a rare autosomal recessive disorder characterized by spondyloepiphyseal dysplasia, episodic lymphopenia, renal failure, and cerebrovascular disease secondary to arteriosclerosis and myointimal hyperplasia. In this paper the authors report the first known application of internal carotid artery (ICA) surgical revascularization to relieve a high-grade focal stenosis of the ICA in a pediatric patient, a 6-year-old boy with SIOD. The clinical presentation, imaging features, operative technique, and postoperative course are described and the molecular genetics, pathophysiology, and treatment considerations in SIOD are discussed...

The authors present the case of a boy who was successfully managed through the spontaneous thrombosis of a cavernous internal carotid artery (ICA) aneurysm, the subsequent occlusion of the ICA, its recanalization, and ultimate endovascular sacrifice, using only two angiograms because of the diagnostic capability of CT angiography. Spontaneous recanalization of the ICA following occlusion in the setting of a giant aneurysm has not been previously reported.

Identification of the origin of the central retinal artery (CRA) is imperative in tailoring angiographic studies to resolve a given clinical problem. A case with dual ophthalmic arteries (OAs), characterized by different origins and distinct branching patterns, is documented for training purposes. Pre-clinical diagnosis of a 9-year-old child who presented with a sharp wire in the left-side eyeball was primarily corneal laceration. For imaging, a selected six-vessel angiographic study with the transfemoral approach was performed...

Reductions in brain volumes represent a neurobiological signature of fetal alcohol spectrum disorders (FASD). Less clear is how regional brain tissue reductions differ after normalizing for brain size differences linked with FASD and whether these profiles can predict the degree of prenatal exposure to alcohol. To examine associations of regional brain tissue excesses/deficits with degree of prenatal alcohol exposure and diagnosis with and without correction for overall brain volume, tensor-based morphometry (TBM) methods were applied to structural imaging data from a well-characterized, demographically homogeneous sample of children diagnosed with FASD (n = 39, 9...

BACKGROUND: Recently, magnetoencephalography (MEG) based real-time brain computing interfaces (BCI) have been developed to enable novel and promising methods for neuroscience research. It is well known that artifact rejection prior to source localization largely enhances the localization accuracy. However, many BCI approaches neglect real-time artifact removal due to its time consuming process. NEW METHOD: The method (referred to as ocular and cardiac artifact rejection for real-time analysis, OCARTA) is based on constrained independent component analysis (cICA), where a priori information of the underlying source signals is used to optimize and accelerate signal decomposition...

Down syndrome, the most common single cause of human birth defects, produces alterations in physical growth and mental retardation. If missed before birth, the early detection of Down syndrome is crucial for the management of patients and disease. However, the diagnostic accuracy for pediatricians prior to cytogenetic results is moderate and the access to specialists is limited in many social and low-economic areas. In this study, we propose a simple, non-invasive and automated framework for Down syndrome detection based on disease-specific facial patterns...

Pipeline Embolization Devices (PEDs) have been shown to be effective for intracranial internal carotid artery (ICA) aneurysms, and are now approved by the FDA specifically for this use. Potential pitfalls, however, have not yet been described in the pediatric neurosurgical literature. The authors report on a 10-year-old boy who presented to the Barrow Neurological Institute after progressive visual decline. He had undergone placement of a total of 7 telescoping PEDs at another facility for a large ICA aneurysm...

Congenital absence of the internal carotid artery (ICA) is an extremely rare vascular anomaly. Aplasia and displacement of the horizontal portion of the petrous carotid artery have been described in a patient with mandibulofacial dysostosis. To the best of our knowledge, the association between Goldenhar syndrome and ipsilateral ICA agenesis has emerged only in one case documented in the medical literature to date. We describe here a case that illustrates the association of Goldenhar syndrome with contralateral agenesis of the ICA incidentally detected on brain magnetic resonance imaging and subsequently confirmed on magnetic resonance angiography and high resolution computed tomography...

BACKGROUND: Evidence suggests that obsessive-compulsive disorder (OCD) is associated with a dysfunction in the cortico-striatal-thalamic-cortical (CSTC) circuitry. Resting state functional connectivity magnetic resonance imaging (rs-fcMRI) allows measurements of resting state networks (RSNs), brain networks that are present at 'rest'. However, although OCD has a typical onset during childhood or adolescence, only two other studies have performed rs-fcMRI comparisons of RSNs in children and adolescents with OCD against healthy controls...

Relating measures of electroencephalography (EEG) back to the underlying sources is a long-standing inverse problem. Here we propose a new method to estimate the EEG sources of identified electrophysiological states that represent spontaneous activity, or are evoked by a stimulus, or caused by disease or disorder. Our method has the unique advantage of seamlessly integrating a statistical significance of the source estimate while efficiently eliminating artifacts (e.g., due to eye blinks, eye movements, bad electrodes)...
