Moya Moya Disease (MMD) is characterised by idiopathic vasculopathy affecting the terminal internal carotid arteries resulting in the formation of extensive collaterals at the base of the brain, leptomeninges and parenchymal regions with resultant infarcts and bleeds. Four children presented with clinico-radiological features suggestive of Moyamoya disease/syndrome. This includes global developmental delay, recurrent seizures, transient ischaemic attacks and impaired vision. The first patient had vision of 6/15 in both eyes with bilateral optic disc pallor...

CLINICAL CASE: A 43-year-old woman in remission from T- cell acute lymphoblastic leukaemia was referred to our hospital with suspected leukaemic retinitis. The funduscopic examination of her left eye revealed multifocal yellow-white peripheral retinitis and retinal haemorrhage. The patient was treated for cytomegalovirus retinitis after an extended haematological investigation showed no abnormalities. Initial improvement was followed by papillitis in the left eye and motility restriction in the right eye...

Moyamoya disease in children is a rarely diagnosed entity. Frequent headache is the first symptom of the disease. Headache associated with moya-moya disease (HAMD) is a separated entity reported in the literature. Variants of onset, a spectrum of primary diagnoses and diagnosis verification rate of moyamoya disease in 7 children are presented. A clinical case of moya-moya disease in a 9-year boy, who was primarily diagnosed with migraine with aura, is reported. The results presented by the authors as well as literature data indicate the necessity of using magnetic-resonance angiography in children with headache attacks and focal neurologic symptoms to identify this progressive vascular pathology and timely recommend a surgical treatment...

OBJECTIVES: Time-of-flight (TOF) magnetic-resonance-angiography (MRA) identifies vessel pathology in cerebrovascular disease. At 7.0 T, the clinical performance of TOF-MRA is constrained owing to radio frequency power deposition. We studied the diagnostic value of whole-brain MPRAGE-based MRA as an alternative imaging technique in comparison to the clinical standard 3.0 T TOF-MRA. METHODS: Patients with stroke and/or moya-moya disease were included. TOF-MRA was performed at 3...

BACKGROUND: Moya Moya disease (MMD) is one of the most common cerebro-vascular diseases in children resulting in stroke. Surgical revascularization aims at improving the perfusion to the 'at-risk' ischemic brain. Several factors including peri-operative anesthetic related ones, affect the outcome in these children. This study was performed with the aim to explore the role of anesthetic techniques, pharmacological agents and perioperative management strategies on the neurological outcome following an indirect revascularization procedure for the treatment of MMD...

Background.  Pregnancy-associated malaria (PAM) remains a significant health concern in sub-Saharan Africa. Cross-sectional studies report that iron might be associated with increased malaria morbidity, raising fears that current iron supplementation policies will cause harm in the present context of increasing resistance against intermittent preventive treatment in pregnancy (IPTp). Therefore, it is necessary to assess the relation of iron levels with malaria risk during the entire pregnancy. Methods.  To investigate the association of maternal iron levels on malaria risk in the context of an IPTp clinical trial, 1005 human immunodeficiency virus-negative, pregnant Beninese women were monitored throughout their pregnancy between January 2010 and May 2011...

BACKGROUND: Ultrasound (US) is the first-line diagnostic study for evaluating gallstone disease and is considered the test of choice for diagnosing acute cholecystitis (AC). However, computed tomography (CT) is used widely for the evaluation of abdominal pain and is often obtained as a first abdominal imaging test, particularly in cases in which typical clinical signs of AC are absent or other possible diagnoses are being considered. We hypothesized that CT is more sensitive than US for diagnosing AC...

STUDY QUESTION: How does the estimated prevalence of infertility among 30- to 49-year-old women vary when using different approaches to its measurement? SUMMARY ANSWER: The prevalence of women with difficulties in conceiving differed widely according to the measurement approach adopted. WHAT IS KNOWN ALREADY: Establishing the true magnitude of infertility as a public health problem is challenging, given that it is not categorized as a disability or chronic condition and may be largely unreported...

Treatments for head and neck cancers are generally complex and debilitating. Surgery, often mutilating, profoundly affects the relationship between oneself and others and causes verbal communication, breathing and swallowing difficulties. The functional and aesthetic sequelae are a constant reminder to the patient of the disease and make them conscious of their appearance.

The short range revival of an arbitrary monochromatic optical field, which propagates in a quadratic GRIN rod, is a well-known effect that is established assuming the first-order approximation of the propagation operator. We discuss the revival and multiple splitting of an off-axis Gaussian beam propagating to relatively long distances in a quadratic GRIN medium. These effects are obtained assuming the second-order approximation of the propagation operator in this medium.

Glioblastoma are malignant highly vascularized brain tumours, which feature large oedema resulting from tumour-promoted vascular leakage. The pro-permeability factor Semaphorin3A (Sema3A) produced within glioblastoma has been linked to the loss of endothelial barrier integrity. Here, we report that extracellular vesicles (EVs) released by patient-derived glioblastoma cells disrupt the endothelial barrier. EVs expressed Sema3A at their surface, which accounted for in vitro elevation of brain endothelial permeability and in vivo vascular permeability, in both skin and brain vasculature...

Shoulder pain is one of the most common musculoskeletal pathologies. Treatment by ESWT (extracorporeal shockwave therapy) has emerged as an alternative when conservative treatment fails in rotator cuff calcific tendinopathy, prior to invasive procedures. The clinical efficacy of ESWT in non-calcific tendinopathy remains controversial. The good results in the treatment of rotator cuff calcifications, have led to indications of ESWT being expanded to other shoulder pathologies. We review the current state of indications and evidence based practice...

People who suffer from severe motor disabilities have difficulties to communicate with others or to interact with their environment using natural, i.e., muscular channels. These limitations can be overcome to some extent by using brain-computer interfaces (BCIs), because such systems allow users to communicate on the basis of their brain activity only. Among the several types of BCIs for spelling purposes, those that rely on the P300 event related potential-P300-based spellers-are chosen preferentially due to their high reliability...

With the idea of improving and advancing the design and preparation of new reagents based on cationic surfactants for gene therapy, two luminescent metallosurfactants derived from the [Ru(2,2'-bpy)3](2+) complex were synthesized. Their interaction with DNA and the effect they exert on the conformation of the polynucleotide were studied by using different techniques. The equilibrium binding constants, Kb, of the two surfactants to DNA were obtained at different molar ratios X=[surfactant]/[DNA]. The observed sigmoidal dependence of Kb on X confirms the cooperative character of the binding...

This paper presents the design of radial basis function geometric bioinspired networks and their applications. Until now, the design of neural networks has been inspired by the biological models of neural networks but mostly using vector calculus and linear algebra. However, these designs have never shown the role of geometric computing. The question is how biological neural networks handle complex geometric representations involving Lie group operations like rotations. Even though the actual artificial neural networks are biologically inspired, they are just models which cannot reproduce a plausible biological process...
