Human hydrocephalus is a common medical condition that is characterized by abnormalities in the flow or resorption of cerebrospinal fluid (CSF), resulting in ventricular dilatation. Human hydrocephalus can be classified into two clinical forms, congenital and acquired. Hydrocephalus is one of the complex and multifactorial neurological disorders. A growing body of evidence indicates that genetic factors play a major role in the pathogenesis of hydrocephalus. An understanding of the genetic components and mechanism of this complex disorder may offer us significant insights into the molecular etiology of impaired brain development and an accumulation of the cerebrospinal fluid in cerebral compartments during the pathogenesis of hydrocephalus. Genetic studies in animal models have started to open the way for understanding the underlying pathology of hydrocephalus. At least 43 mutants/loci linked to hereditary hydrocephalus have been identified in animal models and humans. Up to date, 9 genes associated with hydrocephalus have been identified in animal models. In contrast, only one such gene has been identified in humans. Most of known hydrocephalus gene products are the important cytokines, growth factors or related molecules in the cellular signal pathways during early brain development. The current molecular genetic evidence from animal models indicate that in the early development stage, impaired and abnormal brain development caused by abnormal cellular signaling and functioning, all these cellular and developmental events would eventually lead to the congenital hydrocephalus. Owing to our very primitive knowledge of the genetics and molecular pathogenesis of human hydrocephalus, it is difficult to evaluate whether data gained from animal models can be extrapolated to humans. Initiation of a large population genetics study in humans will certainly provide invaluable information about the molecular and cellular etiology and the developmental mechanisms of human

Posthemorrhagic hydrocephalus is a severe complication following intracranial hemorrhage. Posthemorrhagic hydrocephalus is often associated with high morbidity and mortality and serves as an important clinical predictor of adverse outcomes after intracranial hemorrhage. Currently, no effective medical intervention exists to improve functional outcomes in posthemorrhagic hydrocephalus patients because little is still known about the mechanisms of posthemorrhagic hydrocephalus pathogenesis. Because a better understanding of the posthemorrhagic hydrocephalus pathogenesis would facilitate development of clinical treatments, this is an active research area. The purpose of this review is to describe recent progress in elucidation of molecular mechanisms that cause posthemorrhagic hydrocephalus. What we are certain of is that the entry of blood into the ventricular system and subarachnoid space results in release of lytic blood products which cause a series of physiological and pathological changes in the brain. Blood components that can be linked to pathology would serve as disease biomarkers. From studies of posthemorrhagic hydrocephalus, such biomarkers are known to mutually synergize to initiate and promote posthemorrhagic hydrocephalus progression. These findings suggest that modulation of biomarker expression or function may benefit posthemorrhagic hydrocephalus patients.

Full Text Available Abstract Background Tourette Syndrome (TS is a neurodevelopmental disorder of childhood. Learning disabilities are frequently comorbid with TS. Using the largest sample of TS patients ever reported, we sought to identify differences between subjects with TS only and subjects with TS and a comorbid learning disability. Methods We used the Tourette Syndrome International Consortium database (TIC to compare subjects with comorbid Tourette Syndrome and learning disabilities (TS + LD to subjects who did not have a comorbid learning disability (TS - LD. The TIC database contained 5,500 subjects. We had usable data on 5,450 subjects. Results We found 1,235 subjects with TS + LD. Significant differences between the TS + LD group and the TS - LD group were found for gender (.001, age onset (.030, age first seen (.001, age at diagnosis (.001, prenatal problems (.001, sibling or other family member with tics (.024, two or more affected family members (.009, and severe tics (.046. We used logistic modeling to identify the optimal prediction model of group membership. This resulted in a five variable model with the epidemiologic performance characteristics of accuracy 65.2% (model correctly classified 4,406 of 5,450 subjects, sensitivity 66.1%, and specificity 62.2%. Conclusion Subjects with TS have high prevalence rates of comorbid learning disabilities. We identified phenotype differences between the TS - LD group compared to TS + LD group. In the evaluation of subjects with TS, the presence of a learning disability should always be a consideration. ADHD may be an important comorbid condition in the diagnosis of LD or may also be a potential confounder. Further research on etiology, course and response to intervention for subjects with TS only and TS with learning disabilities is needed.

Leadership and learning disability nursing.

Jukes, Mark; Aspinall, Susan-Louise

Leadership is seen as critical for the transformation of learning disability services and has been further emphasised since the publication of Transforming Care, the Department of Health's response to the review of events at Winterbourne View. What is clear within learning disability nursing and services is the demand for leadership in the quest for improving the quality and effectiveness of services across health and social care. This article discusses the challenges for the undergraduate learning disability nurse with the recommendation to pursue a framework that promotes and focuses on integrating knowledge transfer into services for people with a learning disability. It explores practice change using the Promoting Action on Research Implementation in Health Services (PARiHS) framework, and the example of the involvement of service users in practitioner training on the Mental Capacity Act 2005 and consent and capacity to consent for treatment.

Neuropsychiatric features and intellectual difficulties have been reported in studies of Darier's disease. Learning disabilities have never been reported or evaluated systematically in these patients. To assess the prevalence of learning disabilities in 76 patients with Darier's disease, and cognitive functioning in 19 of them. The data were collected by two methods: a questionnaire, as part of a larger study on the clinical characteristics of 76 patients; and neuropsychological measures for the assessment of learning disabilities in 19 of them. Thirty-one of the 76 patients reported learning disabilities (41%) and 56 (74%) reported a family history of learning disabilities. Significant differences were found between the 19 patients evaluated on cognitive tasks and a control group of 42 skilled learners on subtraction and multiplication tasks. Six (32%) of the 19 were identified as having reading difficulties and five (26%) exhibited low performance on the Concentration Performance Test. All patients had general cognitive ability in the average range. Findings suggest an association between Darier's disease and learning disabilities, a heretofore unreported association, pointing to the need to obtain personal and family history of such disabilities in order to refer cases of clinical concern for further study. © 2013 The Authors Journal of the European Academy of Dermatology and Venereology © 2013 European Academy of Dermatology and Venereology.

Many people with learning disabilities are frequently excluded from active involvement in research and, as a result, along with researchers, have questioned research processes. These discussions have influenced how research is undertaken by, and with, people who have learning disabilities. Learning disability research is now increasingly framed as inclusive. This article explores the development of inclusive learning disability research by tracing its background and influences, identifying key characteristics and highlighting some of the challenges in its application. It demonstrates how inclusive research can give people with learning disabilities a voice that will help to inform practice.

This research pursues the crucial question of the differentiation of preadolescents with "Pure" ADHD, comorbid ADHD with learning disabilities, "Pure" learning disabilities and age-matched normal controls. For this purpose, Topographic Mapping of Event-Related Brain Potentials (ERPs) to a Memory Workload Paradigm with visually presented words, Bilateral Electrodermal Activity during cognitive workload and Mangina-Test performance were used. The analysis of Topographic distribution of amplitudes revealed that normal preadolescents were significantly different from "Pure" ADHD (Plearning disabilities (Plearning disabilities (Plearning disabilities have shown a marked reduction of prefrontal and frontal negativities (N450). As for the "Pure" Learning Disabled preadolescents, very small positivities (P450) in prefrontal and frontal regions were obtained as compared to the other pathological groups. Bilateral Electrodermal Activity during cognitive workload revealed a significant main effect for groups (P<0.00001), Left versus Right (P=0.0029) and sessions (P=0.0136). A significant main effect for the Mangina-Test performance which separated the four groups was found (P<0.000001). Overall, these data support the existence of clear differences and similarities between the pathological preadolescent groups as opposed to age-matched normal controls. The psychophysiological differentiation of these groups, provides distinct biological markers which integrate central, autonomic and neuropsychometric variables by targeting the key features of these pathologies for diagnosis and intervention strategies and by providing knowledge for the understanding of normal neurocognitive processes and functions.

There are several types of hydrocephalus, which are characterized based on the location of the cerebrospinal fluid (CSF) accumulation. Physical features of animals with congenital hydrocephalus may include a dome-shaped skull, persistent fontanelle, and bilateral ventrolateral strabismus. Medical therapy involves decreasing the production of CSF. The most common surgical treatment is placement of a ventriculoperitoneal shunt. Postoperative complications may include infection, blockage, drainage abnormalities, and mechanical failure. Copyright © 2016 Elsevier Inc. All rights reserved.

Cognitive disorders in children's hydrocephalus.

Science.gov (United States)

Zielińska, Dorota; Rajtar-Zembaty, Anna; Starowicz-Filip, Anna

Hydrocephalus is defined as an increase of volume of cerebrospinal fluid in the ventricular system of the brain. It develops as a result of cerebrospinal fluid flow disorder due to dysfunctions of absorption or, less frequently, as a result of the increase of its production. Hydrocephalus may lead to various cognitive dysfunctions in children. In order to determine cognitive functioning in children with hydrocephalus, the authors reviewed available literature while investigating this subject. The profile of cognitive disorders in children with hydrocephalus may include a wide spectrum of dysfunctions and the process of neuropsychological assessment may be very demanding. The most frequently described cognitive disorders within children's hydrocephalus include attention, executive, memory, visual, spatial or linguistic dysfunctions, as well as behavioral problems.

Our study objects were two groups, as the first group 90 patients with spinal dysraphism where neurosurgery operations were done and classified types of dysraphism. At myelomeningocele hydrocephalus has dominated and in a percent of appearance and as acute of its active form was 97% of hydrocephalus form where subjected to cerebrospinal liquid derivation with ventriculo -peritoneal shunt in comparison with meningocele we do not have involvation of spinal nerve element, hydrocephalus takes active form with intervention indication in 60% of cases. Reflection in shown deficit aspect is totally different at myelomeningoceles where lower paraplegia dominate more than paraparesis. The second patient operative technique developed by hydrocephalus with neurosurgical intervention indication has to do with placing of (VP) ventriculo- peritoneal system (shant) at myelomeningoceles with hydrocephalus 58 cases and 12 cases meningoceles with hydrocephalus. Post operative meningitis (shant meningitis): from 70 operated cases of hydrocephalus with spinal dysraphism shunts complications from all types are just cases. Finally that appearance of hydrocephalus compared at spinal dysraphism dominate at myellomeningoceles as in notice time aspect, it is persisting and further acute, with vital motivation for neurosurgical

Learning disability nurses have a key role in addressing the health inequalities experienced by people with learning disabilities. People with learning disabilities are less likely to participate in bowel screening than other sectors of the population, despite there being evidence of this population being at an increased risk of developing bowel cancer. There are a range of barriers at individual and systemic levels that impact on participation in bowel screening by people with learning disabilities. Actions to address these barriers have been identified in the literature and learning disability nurses are a key agent of change in enabling people with learning disabilities to participate in the national screening programmes.

Sociological approaches to the understanding of learning disabilities are perhaps not as fully developed as they might be. Wittgenstein's notion of the language game is elucidated, and its relevance to the analysis of learning disabilities as a social phenomenon is explained. This gives some insight into an alternative conception of what learning disabilities might be, and why people who are classified as having learning disabilities continue, to some extent, to be excluded from full participation in society.

Investigating alternative conceptions in learning disabled students

Science.gov (United States)

Cole, Terry Stokes

Science teachers have long noticed the fact that their students come to school with their own concepts, produced from daily experiences and interactions with the world around them. Sometimes these ideas are in agreement with accepted scientific theories, but often they are not. These "incorrect" ideas, or "misconceptions" have been the focus of many studies, which can be helpful to teachers when planning their lessons. However, there is a dearth of information that is geared specifically to students with learning disabilities. These students generally have deficits in areas of perception and learning that could conceivably influence the way they formulate concepts. The purpose of this study was to examine the concepts held by students with learning disabilities on the causes of the day/night cycle, the phases of the moon, and the seasons. An interview format was judged to be the best method of ensuring that the students' ideas were clearly documented. The subjects were five, sixth-grade students in a city school, who had been determined to have a learning disability. In examining the results, there did not seem to be any direct link between the type of misconception formed and the learning deficit of the child. It seemed more likely that students formed their concepts the way students usually do, but the various disabilities they exhibited interfered with their learning of more appropriate conceptions. The results of this study will be helpful to science teachers, curriculum planners, or anyone who works with students who have learning disabilities. It is hoped that this will begin to fill a void in the area of learning disabilities research.

Magnetic resonance images of children with hydrocephalus often include a rim of hyperintensity in the periventricular white matter (halo). The purpose of this study was to decide between the hypothesis that the halo is caused by cerebrospinal fluid (CSF) flow during the cardiac cycle, and the alternate hypothesis that the halo is caused by anatomical changes (stretching and compression of white matter). Participants were selected from a multicenter imaging study of pediatric hydrocephalus. We compared 19 children with hydrocephalus to a group of 52 controls. We quantified ventricle enlargement using the frontal-occipital horn ratio. We conducted qualitative and quantitative analysis of diffusion tensor imaging in the corpus callosum and posterior limb of the internal capsule. Parameters included the fractional anisotropy (FA), mean diffusivity, axial diffusivity and radial diffusivity. The halo was seen in 16 of the 19 children with hydrocephalus but not in the controls. The corpus callosum of the hydrocephalus group demonstrated FA values that were significantly decreased from those in the control group (P = 4 . 10 -6 ), and highly significant increases were seen in the mean diffusivity and radial diffusivity in the hydrocephalus group. In the posterior limb of the internal capsule the FA values of the hydrocephalus group were higher than those for the control group (P = 0.002), and higher values in the hydrocephalus group were also noted in the axial diffusivity. We noted correlations between the diffusion parameters and the frontal-occipital horn ratio. Our results strongly support the hypothesis that the halo finding in hydrocephalus is caused by structural changes rather than pulsatile CSF flow. (orig.)

People with learning disabilities have poorer health than the general population and experience health inequalities - partly as a result of problems with accessing health services. Health services have a duty to address health inequalities, by making reasonable adjustments to their services so they are more accessible to people with learning disabilities, but this does not always happen. Failure to make reasonable adjustments can have significant adverse effects for people with learning disabilities and their families. Nurses are well placed to implement reasonable adjustments, many of which are simple to do and can save lives.

Hydrocephalus, despite its heterogeneous causes, is ultimately a disease of disordered CSF homeostasis that results in pathological expansion of the cerebral ventricles. Our current understanding of the pathophysiology of hydrocephalus is inadequate but evolving. Over this past century, the majority of hydrocephalus cases has been explained by functional or anatomical obstructions to bulk CSF flow. More recently, hydrodynamic models of hydrocephalus have emphasized the role of abnormal intracranial pulsations in disease pathogenesis. Here, the authors review the molecular mechanisms of CSF secretion by the choroid plexus epithelium, the most efficient and actively secreting epithelium in the human body, and provide experimental and clinical evidence for the role of increased CSF production in hydrocephalus. Although the choroid plexus epithelium might have only an indirect influence on the pathogenesis of many types of pediatric hydrocephalus, the ability to modify CSF secretion with drugs newer than acetazolamide or furosemide would be an invaluable component of future therapies to alleviate permanent shunt dependence. Investigation into the human genetics of developmental hydrocephalus and choroid plexus hyperplasia, and the molecular physiology of the ion channels and transporters responsible for CSF secretion, might yield novel targets that could be exploited for pharmacotherapeutic intervention.

1982-01-01

The relationship between the extension and severity of subarachnoid hemorrhage, as demonstrated by computed tomography (CT), and hydrocephalus secondary to subarachnoid hemorrhage was studied. In 94 cases with subarachnoid hemorrhage, as analyzed by CT scan performed within 7 days after onset, high-density areas in the subarachnoid space were recognized in 61 cases (64%) and secondary hydrocephalus occurred in 22 cases (23%). 17 cases died within 2 weeks, before the occurrence of the hydrocephalus. The CT findings of subarachnoid hemorrhage was classified into 5 types, according to its severity and extension; especially the degree of high density in the basal cistern and/or cisterns around the brain stem was remarked. Secondary hydrocephalus after subarachnoid hemorrhage was observed in 90% of the cases; they had a density higher than a CT number of 60 in the basal cistern and/or cisterns around the brain stem (Type V). The mean interval between the onset of subarachnoid hemorrhage and the appearance of hydrocephalus was 20.6 days. We conclude that a significantly high density of extravasated blood in the subarachnoid space, especially in the basal cistern and/or the cisterns around the brain stem, can be predictive of secondary hydrocephalus after subarachnoid hemorrhage.

Magnetic resonance images of children with hydrocephalus often include a rim of hyperintensity in the periventricular white matter (halo). The purpose of this study was to decide between the hypothesis that the halo is caused by cerebrospinal fluid (CSF) flow during the cardiac cycle, and the alternate hypothesis that the halo is caused by anatomical changes (stretching and compression of white matter). Participants were selected from a multicenter imaging study of pediatric hydrocephalus. We compared 19 children with hydrocephalus to a group of 52 controls. We quantified ventricle enlargement using the frontal-occipital horn ratio. We conducted qualitative and quantitative analysis of diffusion tensor imaging in the corpus callosum and posterior limb of the internal capsule. Parameters included the fractional anisotropy (FA), mean diffusivity, axial diffusivity and radial diffusivity. The halo was seen in 16 of the 19 children with hydrocephalus but not in the controls. The corpus callosum of the hydrocephalus group demonstrated FA values that were significantly decreased from those in the control group (P = 4 . 10{sup -6}), and highly significant increases were seen in the mean diffusivity and radial diffusivity in the hydrocephalus group. In the posterior limb of the internal capsule the FA values of the hydrocephalus group were higher than those for the control group (P = 0.002), and higher values in the hydrocephalus group were also noted in the axial diffusivity. We noted correlations between the diffusion parameters and the frontal-occipital horn ratio. Our results strongly support the hypothesis that the halo finding in hydrocephalus is caused by structural changes rather than pulsatile CSF flow. (orig.)

Congenital unilateral hydrocephalus is extremely uncommon with 18 cases previously reported in the English literature. Two additional newborns with unilateral hydrocephalus are presented. The second baby also presented a mega cisterna magna. This unusual association between Dandy-Walker variant and unilateral hydrocephalus has not been previously reported. Following ventriculo-peritoneal shunt, the babies had a normal cognitive neurodevelopment. The role of cranial computed tomography (CT) in diagnosis and follow-up is emphasized

Transfontanel cranial ultrasonography reliably delineates ventricular size and anatomy in small infants. In these children, it is an excellent primary imaging technique for evaluation of the many clinical problems related to ventricular dilatation. Sonography can be useful for: detecting ventriculomegaly, differentiating nonobstructive ventricular dilatation from obstructive enlargement (hydrocephalus), determining the cause of hydrocephalus; aiding in the temporary management of patients with hydrocephalus; and aiding in the management of patients with permanent ventricular shunts.

This paper compares the midsagittal dimensions of the third and lateral ventricles on MR images in cases of known hydrocephalus and atrophy. Cranial MR studies of 55 age-matched patients, 21 with known hydrocephalus and 28 with atrophy were retrospectively reviewed. Measurements of the genu-to-splenium diameter (G-S) and anterior commissure to corpus callosum distance (AC-CC) were obtained. A volumetric index (VI) was calculated as (G-S) x (AC-CC), and a ratio was calculated as (AC-CC)/(G-S). The volumetric index (VI) was 22% larger in the hydrocephalus group (Student two-tail t test, P > .001,t = -4.23). Sixty-two percent of hydrocephalus patients had either ratios greater than 56% or VIs of a least 20 cm 2

WA10 Working in partnership with people with learning disabilities: academics and people with learning disabilities working together to disseminate the findings of a confidential inquiry into deaths of people with learning disabilities through film.

Science.gov (United States)

Russ, Lesley

2015-04-01

In England, between 2010-2013, a Confidential Inquiry into premature Deaths of People with Learning Disabilities was commissioned by the Department of Health. This took place in SW England led by Norah Fry Research Centre at Bristol University. Findings from the investigations into 247 deaths included that men with learning disabilities die, on average 13 years sooner and women, on average 20 years sooner, than the general population. Over 1/3 (37%) were found to be avoidable, being amenable to good quality healthcare. A number of key recommendations were made which required understanding by a range of audiences including people with learning disabilities and their carers. This workshop will demonstrate how academics can work with actors with learning disabilities to disseminate research findings about a sensitive subject in a thought provoking and accessible way. Academics worked with the MISFITs theatre company to make a DVD about the findings and recommendations of the Confidential Inquiry. The DVD presents the findings of the Confidential Inquiry through the stories of John, Bill, Karen and Emily. It powerfully illustrates the importance of diagnosing and treating illness of people with learning disabilities in a timely and appropriate manner and highlights the measures that could be taken to reduce premature deaths in this population. The session provides an example of how the voices of people with learning disabilities can communicate research messages effectively to people with learning disabilities, health and social care practitioners and others who support the learning disability population. © 2015, Published by the BMJ Publishing Group Limited.

Learning Disabilities in Children: Epidemiology, Risk Factors and Importance of Early Intervention

Directory of Open Access Journals (Sweden)

Beena Johnson

2017-01-01

Full Text Available Children with learning disabilities have significant impairment in reading, writing and mathematics, in spite of normal intelligence and sensory abilities. In reading disability, children will have difficulties in phonemic sensitivity, phonetic decoding, word recognition, word decoding skills and reading comprehension. The lifetime prevalence of learning disability is about 10%. Learning disabilities are more frequently seen in boys compared to girls. There are several risk factors for learning disabilities. Low birth weight, preterm birth, neonatal complications, language delay and epilepsy are important risk factors for learning disabilities in children. Students with learning disabilities have poor scholastic performance, anxiety and significant stress. They have more social, emotional and behavioural problems than those without learning problems. If not remedied at the earliest, learning disabilities will lead to failure in exams and these children may develop stress related disorders. Hence all children with learning problems should be evaluated scientifically at the earliest, for identification of learning disability. By providing scientific guidance and intensive one to one remedial training, learning problems of children can be managed successfully.

Hydrocephalus

International Nuclear Information System (INIS)

Gado, M.H.

1987-01-01

Both hydrocephalus and atrophy imply enlargement of cerebrospinal fluid (CSF) spaces; however, the management is totally different, and the two entities must be carefully differentiated from each other. The following topics are examined; (1) CSF dynamics. The main bulk of CSF production takes place in the lateral ventricles by the choroidal plexuses. Unidirectional flow of CSF brings it into basal cisterns and over cerebral hemispheres. The main bulk of CSF absorption occurs in the superior sagittal sinus via the arachnoid villi. (2) Classification by etiology increased production of CSF vs. obstruction to CSF flow. (3) The diagnosis of hydrocephaulus with CT or MR imaging. Signs of hydrocephalus include enlargement of the ventricles, sparing of sulci, ballooning of the temporal horns, periventricular edema, and progresssion with time. (4) The radiologic evaluation of results of shunt surgery

How older people with learning disabilities perceive ageing.

Science.gov (United States)

Jenkins, Robert

2010-07-01

This article discusses the author's use of reflexivity in trying to gain a better understanding of ageing in older people with learning disabilities. In the general population ageing is viewed in rather negative terms and as a significant life transition. However, for some older people with learning disabilities this transition may go unnoticed because of their past negative life experiences and lack of opportunities. Reflexivity has the potential to provide nurses with greater understanding of the personal perspectives of older people with learning disabilities.

Meister Eduardo Kaehler

2001-01-01

Full Text Available With this article we intend to demonstrate the importance of evaluation and follow up of children with learning disabilities, through a multidisciplinary team. As well as to establish the need of intervention. We evaluate 69 children, from Aline Picheth Public School, in Curitiba, attending first or second grade of elementary school, through general and evolutionary neurological examination, pediatric checklist symptoms, and social, linguistic and psychological (WISC-III, Bender Infantile and WPPSI-figures evaluation. The incidence was higher in boys (84,1%, familiar history of learning disabilities was found in 42%, and writing abnormalities in 56,5%. The most frequent diagnosis was attention deficit and hyperactivity disorder, in 39,1%. With this program, we aimed to reduce the retention taxes and stress the importance of this evaluation, and, if necessary, multidisciplinar intervention in the cases of learning disabilities.

Shortfalls in pediatric hydrocephalus clinical outcome analysis.

Walid, Mohammad Sami; Robinson, Joe Sam

2012-06-01

In this paper, we used search engine technology to study outcome analysis and cost awareness of child hydrocephalus in the literature. The aggregate hospital charges of hydrocephalus treatment procedures for patients years old was extracted from the Nationwide Inpatient Sample (NIS) data. Hydrocephalus literature was probed through the PubMed biomedical search engine. Aggregate hospital charges associated with ventriculo-peritoneal shunting as the principle procedure for patients years old have increased 1.7-fold over a 13-year period to 235.6 million in 2009. Hospital discharges, however, decreased from 3,390 in 1997 to 2,525 in 2009 (25.5% decrease over 13 years). The number of papers in English language indexed by PubMed in relation to child hydrocephalus in humans increased from 81 papers in 1996 to 133 in 2010 (1.6-fold increase), totaling 1,694 over 15 years. Randomized controlled trials published in relation to child hydrocephalus totaled 16 over the same period (0.94% of child hydrocephalus papers). Papers related to child hydrocephalus with "costs and cost analysis" as medical subject heading totaled 13 papers (0.77%). Over the past 15 years, disappointingly the number of printed child hydrocephalus papers appeared to have only plateaued. Strikingly, only a very small number of these papers were directed toward randomized control studies, the sine qua non of high-grade clinical evidence. Moreover, very few papers make reference to cost analysis or economics in the treatment of hydrocephalus - an issue coming increasingly before the nation at this point.

Quantitative RI cisternography in hydrocephalus

Ventriculography and cisterography with 131 I-HSA, and 167 Yb-DTPA were performed in patients with obstructive and normal-pressure hydrocephalus. Radioactivity in the head, blood counts and excretions in the urine were determined. In the patients with obstructive hydrocephalus, the radioactivity reduction in the head was late by the ventricular injection, while it was normal by the lumbar puncture. In the patients with normal-pressure hydrocephalus, the radioactivity reduction curve varied both by the ventricular injection and the lumbar puncture. However, these did not indicate the results of the shunt operation. The external determination of the rate of reduction of radioactivity in the head were parallel with blood radioactivity the urinary excretion rate. In the patients with normal-pressure hydrocephalus, the absorption rate of the spinal fluid decreased independently from the radioactivity curve in the head. (Saito, K.)

Children with hydrocephalus have poor math skills. We investigated the nature of their arithmetic computation errors by comparing written subtraction errors in good readers with hydrocephalus, typically developing good readers of the same age, and younger children matched for math level to the children with hydrocephalus. Children with hydrocephalus made more procedural errors (although not more fact retrieval or visual-spatial errors) than age-matched controls; they made the same number of procedural errors as younger, math-level matched children. We also investigated a broad range of math abilities, and found that children with hydrocephalus performed more poorly than age-matched controls on tests of geometry and applied math skills such as estimation and problem solving. Computation deficits in children with hydrocephalus reflect delayed development of procedural knowledge. Problems in specific math domains such as geometry and applied math, were associated with deficits in constituent cognitive skills such as visual spatial competence, memory, and general knowledge.

Congenital hydrocephalus is an important birth defect, the genetics of which remains incompletely understood. To date, only 4 genes are known to cause Mendelian diseases in which congenital hydrocephalus is the main or sole clinical feature, 2 X-linked (L1CAM and AP1S2) and 2 autosomal recessive (CCDC88C and MPDZ). In this study, we aimed to determine the genetic etiology of familial congenital hydrocephalus with the assumption that these cases represent Mendelian forms of the disease. Exome sequencing combined, where applicable, with positional mapping. We identified a likely causal mutation in the majority of these families (21 of 27, 78%), spanning 16 genes, none of which is X-linked. Ciliopathies and dystroglycanopathies were the most common etiologies of congenital hydrocephalus in our cohort (19% and 26%, respectively). In 1 family with 4 affected members, we identified a homozygous truncating variant in EML1, which we propose as a novel cause of congenital hydrocephalus in addition to its suggested role in cortical malformation. Similarly, we show that recessive mutations in WDR81, previously linked to cerebellar ataxia, mental retardation, and disequilibrium syndrome 2, cause severe congenital hydrocephalus. Furthermore, we confirm the previously reported candidacy of MPDZ by presenting a phenotypic spectrum of congenital hydrocephalus associated with 5 recessive alleles. Our study highlights the importance of recessive mutations in familial congenital hydrocephalus and expands the locus heterogeneity of this condition.

Hydrocephalus is uncommon in horses. However, in recent years, it has become clear that the prevalence of hydrocephalus is greater in Friesian horses than in other breeds probably due to their limited gene pool. Before identification of candidate genes that predispose to the development of hydrocephalus in Friesian horses can be pursued, an in-depth, phenotypic, pathological description of the condition in Friesians would be of great benefit. Our study aimed to characterize the morphology of hydrocephalus in Friesian horses, to support further investigation of the genetic background of this condition. Four stillborn Friesian foals with hydrocephalus were examined macroscopically and microscopically and compared with 2 normal stillborn Friesian foals without hydrocephalus. In all clinical cases, tetraventricular and venous dilatations were observed, together with malformation of the petrosal bone and, as a result, narrowing of the jugular foramen. These observations suggest a communicative hydrocephalus with a diminished absorption of cerebrospinal fluid into the systemic circulation at the venous sinuses due to a distorted, nonfunctional jugular foramen. This type of hydrocephalus is also recognized in humans and dogs and has been linked genetically to chondrodysplasia; this has already been recognized in dwarfism, which is another monogenetic defect in Friesian horses.

Causes of learning disability and epilepsy: a review.

Science.gov (United States)

Prince, Elizabeth; Ring, Howard

2011-04-01

Although the association between learning disability and epilepsy is well known, until relatively recently specific processes underlying this association were relatively poorly understood. However, scientific advances in molecular biology are starting to guide researchers towards descriptions of genetic and pathophysiological processes that may explain why syndromes of epilepsy and learning disability often co-exist. This article will focus largely on three areas of advancing knowledge: insights gained from wider use of genome-wide array comparative genomic hybridization (aCGH), specific insights gained from detailed study of Rett syndrome and the role of abnormalities of astrocytic function in predisposing to both epilepsy and learning disability. The enormous complexity of the biological underpinnings of the co-occurrence of epilepsy and learning disability are becoming apparent. In the future it is likely that research into therapeutic approaches will include, amongst other approaches, investigations of gene structure and expression, the role of astrocytes and the stability of dendritic spines.

Building on previous National Institutes of Health-sponsored symposia on hydrocephalus research, "Opportunities for Hydrocephalus Research: Pathways to Better Outcomes" was held in Seattle, Washington, July 9-11, 2012. Plenary sessions were organized into four major themes, each with two subtopics: Causes of Hydrocephalus (Genetics and Pathophysiological Modifications); Diagnosis of Hydrocephalus (Biomarkers and Neuroimaging); Treatment of Hydrocephalus (Bioengineering Advances and Surgical Treatments); and Outcome in Hydrocephalus (Neuropsychological and Neurological). International experts gave plenary talks, and extensive group discussions were held for each of the major themes. The conference emphasized patient-centered care and translational research, with the main objective to arrive at a consensus on priorities in hydrocephalus that have the potential to impact patient care in the next 5 years. The current state of hydrocephalus research and treatment was presented, and the following priorities for research were recommended for each theme. 1) Causes of Hydrocephalus-CSF absorption, production, and related drug therapies; pathogenesis of human hydrocephalus; improved animal and in vitro models of hydrocephalus; developmental and macromolecular transport mechanisms; biomechanical changes in hydrocephalus; and age-dependent mechanisms in the development of hydrocephalus. 2) Diagnosis of Hydrocephalus-implementation of a standardized set of protocols and a shared repository of technical information; prospective studies of multimodal techniques including MRI and CSF biomarkers to test potential pharmacological treatments; and quantitative and cost-effective CSF assessment techniques. 3) Treatment of Hydrocephalus-improved bioengineering efforts to reduce proximal catheter and overall shunt failure; external or implantable diagnostics and support for the biological infrastructure research that informs these efforts; and evidence-based surgical standardization with

To assess the prevalence and patterns of learning disabilities (LD) in school going children in a northern city of India. The present cross-sectional study comprised of three-staged screening procedure for assessing learning disabilities of 3rd and 4th grade students studying in government schools. The first stage comprised of the teacher identifying at-risk student. In the second stage, teachers assessed at-risk students using Specific Learning Disability-Screening Questionnaire (SLD-SQ). The third stage comprised of assessment of the screen positive students using Brigance Diagnostic Inventory (BDI) part of NIMHANS Index of Specific Learning Disabilities for identifying the cases of LD. A total of 1211 (33.6%) children out of the total screened (n = 3600) were identified as at-risk by the teachers at the first stage. Of them, 360 were found to screen positive on the second stage using SLD-SQ. The most common deficits were missing out words or sentences while reading, misplacing letters or words while reading or writing, and making frequent mistake in spelling while writing or reading. Of these, 108 children were confirmed to have learning disability on the third stage using BDI, which represented 3.08% of the total population. Learning disability is an important concern in young school aged children. Early identification of such students can help in early institution of intervention and suitable modifications in teaching techniques.

Intramedullary hemangioblastomas are rare benign vascular tumors, infrequent in pediatric patients. Clinical symptoms vary according to the age of presentation, tumor size, location, and concomitant syringomyelia. This is the second reported case of hemangioblastoma presenting with acute hydrocephalus. A 3-month-old infant with acute hydrocephalus was asymptomatic after a ventriculoperitoneal shunt was placed. She returned 3 months later with irritability, acute paraplegia, and respiratory distress. Magnetic resonance imaging (MRI) showed an intramedullary T8-T9 tumor with syringomyelia. She underwent surgical resection with good results during the 6-month follow-up. Intramedullary tumors may present as hydrocephalus and other nonspecific symptoms, with invariably delayed diagnosis in children, but must be considered in suspicious cases.

People with learning disabilities have poorer health than their non-disabled peers, and are less likely to access screening services than the general population. The National Development Team for Inclusion and the Norah Fry Research Centre developed a toolkit and guidance to improve uptake of five national (English) screening programmes (one of which is delivered through local programmes), based on work to improve access by people with learning disabilities in the south west peninsula of the UK. This article describes the findings in relation to the five English screening programmes and suggests ways to improve uptake of cancer screening by people with learning disabilities.

Infantile hydrocephalus: a review of epidemiology, classification and causes

Science.gov (United States)

Tully, Hannah M; Dobyns, William B

2015-01-01

Hydrocephalus is a common but complex condition caused by physical or functional obstruction of CSF flow that leads to progressive ventricular dilatation. Though hydrocephalus was recently estimated to affect 1.1 in 1,000 infants, there have been few systematic assessments of the causes of hydrocephalus in this age group, which makes it a challenging condition to approach as a scientist or as a clinician. Here, we review contemporary literature on the epidemiology, classification and pathogenesis of infantile hydrocephalus. We describe the major environmental and genetic causes of hydrocephalus, with the goal of providing a framework to assess infants with hydrocephalus and guide future research. PMID:24932902

Pintrich, P R; Anderman, E M; Klobucar, C

1994-01-01

The present study examines several cognitive and motivational variables that distinguish children with learning disabilities (n = 19) from children without learning disabilities (n = 20). The total sample included 30 males and 9 females and was composed of white, fifth-grade students from a middle-class community in the Midwest. Results showed that although the students with learning disabilities displayed lower levels of metacognitive knowledge and reading comprehension, they did not differ from the students without learning disabilities on self-efficacy, intrinsic orientation, or anxiety. In addition, they did not show any signs of learned helplessness, although they did tend to attribute success and failure to external causes more often than the students without learning disabilities. Using a cluster analysis that grouped individuals, we found that differences in the motivational and cognitive variables cut across a priori categories of children with and without learning disabilities. Three clusters were formed: one with high comprehension, motivation, and metacognition (mostly children without learning disabilities); one with low levels of comprehension and metacognition but high intrinsic motivation (all children with learning disabilities); and one with low intrinsic motivation but average comprehension, metacognition, and attributional style (approximately equal numbers of children with and without learning disabilities). Implications for diagnosis and intervention for students with learning disabilities are discussed.

Classification of hydrocephalus: critical analysis of classification categories and advantages of "Multi-categorical Hydrocephalus Classification" (Mc HC).

Science.gov (United States)

Oi, Shizuo

2011-10-01

Hydrocephalus is a complex pathophysiology with disturbed cerebrospinal fluid (CSF) circulation. There are numerous numbers of classification trials published focusing on various criteria, such as associated anomalies/underlying lesions, CSF circulation/intracranial pressure patterns, clinical features, and other categories. However, no definitive classification exists comprehensively to cover the variety of these aspects. The new classification of hydrocephalus, "Multi-categorical Hydrocephalus Classification" (Mc HC), was invented and developed to cover the entire aspects of hydrocephalus with all considerable classification items and categories. Ten categories include "Mc HC" category I: onset (age, phase), II: cause, III: underlying lesion, IV: symptomatology, V: pathophysiology 1-CSF circulation, VI: pathophysiology 2-ICP dynamics, VII: chronology, VII: post-shunt, VIII: post-endoscopic third ventriculostomy, and X: others. From a 100-year search of publication related to the classification of hydrocephalus, 14 representative publications were reviewed and divided into the 10 categories. The Baumkuchen classification graph made from the round o'clock classification demonstrated the historical tendency of deviation to the categories in pathophysiology, either CSF or ICP dynamics. In the preliminary clinical application, it was concluded that "Mc HC" is extremely effective in expressing the individual state with various categories in the past and present condition or among the compatible cases of hydrocephalus along with the possible chronological change in the future.

Parenting children with learning disabilities requires a high level of knowledge and access to resources, information and services. In developing countries, however, these resources and services are not always available. Parents in Namibia, a developing country, therefore face challenges addressing children's learning and other developmental disabilities, including challenges related to preventative and supportive interventions. This research focuses on challenges faced by parents as they parent children with learning disabilities in Opuwo, Namibia. In-depth interviews were conducted with eight parents regarding the challenges they face in parenting their children with learning disabilities. Thematic analysis enabled the researchers to identify, analyse and report on themes that emerged from the qualitative interview data. Analysis of the interviews indicated that some participants had only a vague understanding of learning disabilities, as they did not have access to essential knowledge about this phenomenon. They also lacked an awareness of the availability of programmes, services and policies meant to benefit their children with learning disabilities. Participants voiced that they, their children with learning disabilities and community members have stereotypes and prejudices regarding learning disabilities. In this study, most of the children with learning disabilities were raised by single, unemployed parents who seemed to have access to less support from external sources than married couples parenting children with learning disabilities. These single parents are usually not married and because of lack of financial support from the other parent, the majority of them indicated that they struggle to meet the financial and material needs of their children. The researchers concluded that the participants in this study experience a range of challenges in parenting their children with learning disabilities. The main challenges emanate from financial instability, as

to check the use of metacognitive reading strategies in children with learning disabilities and determine whether there is a relationship between their use and text comprehension. the study was conducted on 30 children, aged 8 to 12 years, of both genders, divided into experimental group (EG) - 15 children with learning disabilities; and control group (CG) - 15 children without disability. All children were submitted to the Reading Strategies Scale and Prolec text comprehension subtest. The sample was described in mean, median, minimum and maximum values. Comparative analysis was performed between the groups using the Mann-Whitney test. The degree of correlation between variables was verified by Spearman Correlation Analysis. The significance level was set at 5%. across the total scores of the scale, EG performance was lower in all descriptive measures, with a significant difference compared to CG. The EG achieved a performance close to children without difficulties only in global strategies. The correlation between the use of metacognitive strategies and reading comprehension was positive. children with learning disabilities showed deficits in the use of metacognitive reading strategies when compared to children without learning disabilities. The better the performance in reading strategies, the better textual comprehension was and vice versa, suggesting that metacognitive reading skills contribute to reading comprehension.

Research suggests that the uptake of cervical screening by women with intellectual disabilities (commonly known as learning disabilities within UK policy frameworks, practice areas and health services) is poor compared to women without intellectual disabilities. The present study explored learning disability nurses' experiences of supporting women with intellectual disabilities to access cervical screening in order to examine their role in promoting attendance and elucidate potential barriers and facilitators to uptake. Ten participants recruited from a specialist learning disability service completed a semi-structured interview and data were analysed using experiential thematic analysis. Identified individual barriers included limited health literacy, negative attitudes and beliefs and competing demands; barriers attributed to primary care professionals included time pressures, limited exposure to people with intellectual disabilities and lack of appropriate knowledge, attitudes and skills. Attendance at cervical screening was facilitated by prolonged preparation work undertaken by learning disability nurses, helpful clinical behaviours in the primary care context and effective joint working. © The Author(s) 2014.

Subdural fluid collection and hydrocephalus following cervical schwannoma resection: hydrocephalus resolution after spinal pseudomeningocele repair: case report.

2016-12-01

The authors report the case of a 31-year-old man who developed neck pain and headache 2 months after the uncomplicated resection of a cervical schwannoma. MR imaging revealed infratentorial subdural fluid collections and obstructive hydrocephalus associated with cervical pseudomeningocele. The clinical symptoms, subdural fluid collections, and ventricular dilation resolved after surgical correction of the pseudomeningocele. This report emphasizes that hydrocephalus may be related to disorders of cerebrospinal fluid flow dynamics induced by cervical pseudomeningocele. In these rare cases, both the hydrocephalus and the symptoms are resolved by the simple correction of the pseudomeningocele.

In this paper the author considers the lessons to be drawn from what is termed "inclusive" learning disability research for user involvement around health improvement. Inclusive learning disability research refers to research where people with learning difficulties (intellectual disability) are involved as active participants, as opposed to passive subjects. There is by now a considerable body of such research, developed over the past 25 years. From the review, the author draws attention to areas which can inform practice in involvement of users in a way that adds value.

Learning problems occur in about 5% of school-aged children. Learning disabilities are specific and life-long but present with different school problems at different ages, depending on such factors as age, medical history, family history, and intelligence quotient. Proper individualized diagnosis and treatment plans are necessary to remediate these problems and to offer adequate coping strategies. Many children who have learning problems can be classified into one of two major categories: the dyslexia group or the nonverbal learning disability group. The role of the medical professional is important to guide parents in the diagnostic and therapeutic process.

The purpose of this study was to determine the prevalence of hydrocephalus in patients with vestibular schwannoma. A second objective was to investigate possible etiologies for hydrocephalus in this population by attempting to correlate the incidence and severity of hydrocephalus with tumor volume and extent of fourth ventricular compression. The MRI examinations of 157 adult patients with vestibular schwannoma were retrospectively reviewed. Tumor size was quantified, and the presence of accompanying hydrocephalus was assessed, categorized as communicating type or non-communicating type and then rated as mild, moderate or severe (grades 1-3). Next, the degree of fourth ventricular distortion caused by tumor mass effect was evaluated and categorized as mild, moderate or severe (grades 1-3). Spearman's rank correlation coefficient was used to test the relationships between tumor volume and (1) the extent of fourth ventricular effacement and (2) severity of hydrocephalus. Hydrocephalus was present in 28/157 (18%) cases and was categorized as mild in 11/28 (39%), moderate in 15/28 (54%) and severe in 2/28 (7%). Communicating-type hydrocephalus was present in 17/28 (61%) and non-communicating type in 11/28 (39%). There was a positive correlation between the grade of non-communicating hydrocephalus and tumor volume (r=0.38; P<0.001) and between the severity of fourth ventricular compression and extent of hydrocephalus in this group(r=0.43; P<0.001).

Hydrocephalus is caused by an imbalance of production and absorption of cerebrospinal fluid (CSF) or obstruction of its pathways, resulting in ventricular dilatation and increased intracranial pressure. Imaging plays a crucial role in the diagnosis, differential diagnosis and planning of treatment. This review article presents the different types of hydrocephalus und their typical imaging appearance, describes imaging techniques, and discusses differential diagnoses of the different forms of hydrocephalus. Imaging plays a central role in the diagnosis of hydrocephalus. While magnetic resonance (MR) imaging is the first-line imaging modality, computed tomography (CT) is often the first-line imaging test in emergency patients.

Overcoming the obstacles: Life stories of scientists with learning disabilities

Science.gov (United States)

Force, Crista Marie

Scientific discovery is at the heart of solving many of the problems facing contemporary society. Scientists are retiring at rates that exceed the numbers of new scientists. Unfortunately, scientific careers still appear to be outside the reach of most individuals with learning disabilities. The purpose of this research was to better understand the methods by which successful learning disabled scientists have overcome the barriers and challenges associated with their learning disabilities in their preparation and performance as scientists. This narrative inquiry involved the researcher writing the life stories of four scientists. These life stories were generated from extensive interviews in which each of the scientists recounted their life histories. The researcher used narrative analysis to "make sense" of these learning disabled scientists' life stories. The narrative analysis required the researcher to identify and describe emergent themes characterizing each scientist's life. A cross-case analysis was then performed to uncover commonalities and differences in the lives of these four individuals. Results of the cross-case analysis revealed that all four scientists had a passion for science that emerged at an early age, which, with strong drive and determination, drove these individuals to succeed in spite of the many obstacles arising from their learning disabilities. The analysis also revealed that these scientists chose careers based on their strengths; they actively sought mentors to guide them in their preparation as scientists; and they developed coping techniques to overcome difficulties and succeed. The cross-case analysis also revealed differences in the degree to which each scientist accepted his or her learning disability. While some demonstrated inferior feelings about their successes as scientists, still other individuals revealed feelings of having superior abilities in areas such as visualization and working with people. These individuals revealed

CAPTCHA: Impact on User Experience of Users with Learning Disabilities

Directory of Open Access Journals (Sweden)

Ruti Gafni

2016-12-01

Full Text Available CAPTCHA is one of the most common solutions to check if the user trying to enter a Website is a real person or an automated piece of software. This challenge-response test, implemented in many Internet Websites, emphasizes the gaps between accessibility and security on the Internet, as it poses an obstacle for the learning-impaired in the reading and comprehension of what is presented in the test. Various types of CAPTCHA tests have been developed in order to address accessibility and security issues. The objective of this study is to investigate how the differences between various CAPTCHA tests affect user experience among populations with and without learning disabilities. A questionnaire accompanied by experiencing five different tests was administered to 212 users, 60 of them with learning disabilities. Response rates for each test and levels of success were collected automatically. Findings suggest that users with learning disabilities have more difficulties in solving the tests, especially those with distorted texts, have more negative attitudes towards the CAPTCHA tests, but the response time has no statistical difference from users without learning disabilities. These insights can help to develop and implement solutions suitable for many users and especially for population with learning disabilities.

OBJECTIVE The aim of this study was to report the incidence of and the factors associated with papilledema in children with hydrocephalus. METHODS Patients younger than 15 years of age who had been diagnosed with hydrocephalus and treated by extra-ventricular drainage or ventriculoperitoneal shunt surgery between 2005 and 2015 were retrospectively reviewed. Factors including patient age and sex, etiology of hydrocephalus, duration of signs or symptoms, intracranial pressure (ICP), and presence of papilledema were evaluated. RESULTS Forty-six patients, whose mean age was 6.3 ± 4.7 years, were included in the study. The 19 patients without papilledema had a mean age of 2.7 ± 2.7 years, and the 27 patients with papilledema had a mean age of 8.8 ± 4.2 years (p hydrocephalus were tumor (59%), congenital anomaly (19%), hemorrhage (13%), and infection (9%). CONCLUSIONS Papilledema was more common in patients who were older, who had higher ICP, and whose hydrocephalus had been induced by brain tumor. However, since papilledema was absent in 41% of the children with hydrocephalus, papilledema's absence does not ensure the absence of hydrocephalus, especially in younger patients.

OBJECT Intraventicular hemorrhage (IVH) is a common complication of preterm birth, and the prognosis of IVH is incompletely characterized. The objective of this study was to describe the outcomes of IVH in a population-based cohort with minimal selection bias. METHODS All very preterm (≥ 30 completed weeks) patients born in the province of Nova Scotia were included in a comprehensive database. This database was screened for infants born to residents of Nova Scotia from January 1, 1993, to December 31, 2010. Among very preterm infants successfully resuscitated at birth, the numbers of infants who died, were disabled, developed cerebral palsy, developed hydrocephalus, were blind, were deaf, or had cognitive/language scores assessed were analyzed by IVH grade. The relative risk of each outcome was calculated (relative to the risk for infants without IVH). RESULTS Grades 2, 3, and 4 IVH were significantly associated with an increased overall mortality, primarily in the neonatal period, and the risk increased with increasing grade of IVH. Grade 4 IVH was significantly associated with an increased risk of disability (RR 2.00, p < 0.001), and the disability appeared to be primarily due to cerebral palsy (RR 6.07, p < 0.001) and cognitive impairment (difference in mean MDI scores between Grade 4 IVH and no IVH: -19.7, p < 0.001). No infants with Grade 1 or 2 IVH developed hydrocephalus, and hydrocephalus and CSF shunting were not associated with poorer outcomes when controlling for IVH grade. CONCLUSIONS Grades 1 and 2 IVH have much better outcomes than Grades 3 or 4, including a 0% risk of hydrocephalus in the Grade 1 and 2 IVH cohort. Given the low risk of selection bias, the results of this study may be helpful in discussing prognosis with families of very preterm infants diagnosed with IVH.

Family-Peer Linkages for Children with Intellectual Disability and Children with Learning Disabilities.

Family interactions are potential contexts for children with intellectual and learning disabilities to develop skillful social behaviors needed to relate effectively with peers. This study examined problem solving interactions within families of elementary school-age children (7-11 years) with intellectual disability (n = 37), specific learning disabilities (n =48), and without disabilities (n = 22). After accounting for group differences in children's behaviors and peer acceptance, across all groups, mothers' behaviors that encouraged egalitarian problem solving predicted more engaged and skillful problem solving by the children. However, mothers' controlling, directive behaviors predicted fewer of these behaviors by the children. Fathers' behaviors had mixed associations with the children's actions, possibly because they were reactive to children's unengaged and negative behaviors. For the children, greater involvement, more facilitative behaviors, and less negativity with their families were associated with greater acceptance from their peers, supporting family-peer linkages for children at risk for peer rejection.

In the present study, we developed a new event-related potentials (ERPs) stimulator system applicable to simultaneous audio visual stimuli, and tested it clinically on healthy adults and patients with learning disabilities (LD), using Japanese language task stimuli: hiragana letters, kanji letters, and kanji letters with spoken words. (1) The origins of the P300 component were identified in these tasks. The sources in the former two tasks were located in different areas. In the simultaneous task stimuli, a combination of the two P300 sources was observed with dominance in the left posterior inferior temporal area. (2) In patients with learning disabilities, those with reading and writing disability showed low amplitudes in the left hemisphere in response to visual language task stimuli with kanji and hiragana letters, in contrast to healthy children and LD patients with arithmetic disability. (3) To evaluate the effect of methylphenidate (10 mg) on ADD, paired-associate ERPs were recorded. Methylphenidate increased the amplitude of P300.

Few systematic assessments of developmental forms of hydrocephalus exist. We reviewed MRIs and clinical records of patients with infancy-onset hydrocephalus. Among 411 infants, 236 had hydrocephalus with no recognizable extrinsic cause. These children were assigned to one of five subtypes and compared on the basis of clinical characteristics, developmental and surgical outcomes. At an average age of 5.3 years, 72% of children were walking independently and 87% could eat by mouth. 18% had epilepsy. Distinct patterns of associated malformations and syndromes were observed within each subtype. On average, children with aqueductal obstruction, cysts and encephaloceles had worse clinical outcomes than those with other forms of developmental hydrocephalus. 53% of surgically-treated patients experienced at least one shunt failure, but hydrocephalus associated with posterior fossa crowding required fewer shunt revisions. We conclude that each subtype of developmental hydrocephalus is associated with distinct clinical characteristics, syndromology, and outcomes, suggesting differences in underlying mechanisms.

The correlation between the findings on MR images and CT findings, clinical symptoms, and the results of various specific investigations was determined. MR imaging was more sensitive in demonstrating the pathology of the periventricular tissue in hydrocephalus than was CT scanning, although the overall correlation between MR and CT findings was good. The authors classified the periventricular high-signal intensities (PVHI) of MR images into 4 types according to the extension and grade of the PVHI. Type 0 has no PVHI. Type I has a band of the PVHI around the wall of the lateral ventricles, including the corpus callosum and the septum pellucidum. In Type III, PVHI extended half of the width of the periventricular white matter, while in Type IV PVHI occupied the entire white matter. CT scans showed periventricular lucency (PVL) only in the periventricular white matter, especially surrounding the anterior horn, but the PVHI was visible not only in wider areas of the entire periventricular white matter, but also in the corpus callosum and the septum pellucidum. The PVHI seen in case of hydrocephalus due to posterior fossa tumors was characterized by PVHI of Type I; the PVHI disappeared after CSF shunting in all cases. There was no PVHI in the cases of marked hydrocephalus due to aqueductal stenosis, which appeared to be compensated for a long period. In the cases of normal-pressure hydrocephalus, there were various types of PVHI. There was no correlation between the types of PVHI and the grade of ventriculomegaly. There was, however, a close correlation between the types of PVHI on MR images and the clinical symptoms, and the cerebral blood flow in cases of normal-pressure hydrocephalus. In some patients with normal-pressure hydrocephalus, the PVHI improved and the cerebral blood flow increased after cerebrospinal fluid shunting. (J.P.N.)

Hydrocephalus requiring external ventricular drain (EVD) or shunt placement commonly complicates aneurysmal subarachnoid hemorrhage (SAH), but its frequency is not as well known for nonaneurysmal SAH (NA-SAH). Those with diffuse bleeding may have greater risk of hydrocephalus compared to those with a perimesencephalic pattern. We evaluated the frequency of hydrocephalus in NA-SAH and whether imaging factors could predict the need for EVD and shunting. We collected admission clinical and imaging variables for 105 NA-SAH patients, including bicaudate index (BI), Hijdra sum score (HSS), intraventricular hemorrhage (IVH) score, modified Fisher scale (mFS), and bleeding pattern. Hydrocephalus was categorized as acute (need for EVD) or chronic (shunt). We applied logistic regression to determine whether hydrocephalus risk was independently related to bleeding pattern or mediated through blood volume or ventriculomegaly. Acute hydrocephalus was seen in 26 (25%) patients but was more common with diffuse (15/28, 54%) versus perimesencephalic (10/59, 17%, p hydrocephalus had worse clinical grade and higher BI, HSS, and IVH scores. Adjusting the relationship between hydrocephalus and diffuse bleeding for HSS (but not BI) nullified this association. Nine (35%) patients requiring EVD eventually required shunting for chronic hydrocephalus, which was associated with greater blood burden but not poor clinical grade. Acute hydrocephalus occurs in one-quarter of NA-SAH patients. The greater risk in diffuse bleeding appears to be mediated by greater cisternal blood volume but not by greater ventriculomegaly. Imaging characteristics may aid in anticipatory management of hydrocephalus in NA-SAH.

Chronic communicating hydrocephalus was produced in adult dogs by injection of silastic into the subarachnoid space. Electron microscopy was used to verify the sequence of pathologic changes in the ventricular wall. The pathologic findings were correlated with cisternographic images and measurements of cerebrospinal fluid (CSF) pressure. Early in hydrocephalus, the CSF pressure was increased and cisternograms showed ventricular entry and clearing; the ependyma was stretched and fluid accumulated in subependymal regions. In animals with chronic hydrocephalus, the CSF pressure was normal and cisternograms disclosed radioactivity persisting in the ventricles. At this time the ependyma was severely damaged, the subependymal white matter showed enlargement of the extracellular space, and degenerative changes were present in axons and myelin sheaths

Hydrocephalus occurs due to a blockage in the transmission of cerebrospinal fluid (CSF) in either the ventricles or subarachnoid space. Characteristics of this condition include increased intracranial pressure, which can result in neurologic deterioration [1]. Magnetic resonance elastography (MRE) is an imaging technique that estimates the mechanical properties of tissue in vivo. While some investigations of brain tissue have been performed using MRE [2,3,4,5], the effects due to changes in interstitial pressure and fluid content on the mechanical properties of the brain remain unknown. The purpose of this work is to assess the potential of MRE to differentiate between the reconstructed properties of normal and hydrocephalic brains. MRE data was acquired in 18 female feline subjects, 12 of which received kaolin injections resulting in an acute form of hydrocephalus. In each animal, four MRE scans were performed during the process including one pre-injection and three post-injection scans. The elastic parameters were obtained using a subzone-based reconstruction algorithm that solves Navier's equations for linearly elastic materials [6]. The remaining cats were used as controls, injected with saline instead of kaolin. To determine the state of hydrocephalus, ventricular volume was estimated from segmenting anatomical images. The mean ventricular volume of hydrocephalic cats significantly increased (P ~ 0.5) for the control cats. Also, there was an observable increase in the recorded elastic shear modulus of brain tissue in the normal and hydrocephalic acquisitions. Results suggest that MRE is able to detect changes in the mechanical properties of brain tissue resulting from kaolin-induced hydrocephalus, indicating the need for further study.

Brain scintigraphy is a simple, innocuous and valuable diagnostic method. Particulary in children, in order to minimize damage by examination, brain scintigraphy should be the first examination for patients, before other diagnostic methods such as cerebral angiography and pneumoencephalography. In the 3 years between Jan. 1970 and Dec. 1972, 235 children under the age of 15 years had brain scintigraphy with sup(99m)Tc pertechnetate at the Tokyo Women's Medical College Hospital. The authors especially attended to the findings of scintigrams in children with hydrocephalus. 29 children with non-neoplastic hydrocephalus were scanned with sup(99m)Tc pertechnetate: noncommunicating hydrocephalus; 9; hydroencephalodysplasia; 4; Chiari Arnold malformation; 1; cranium bifidum; 2; communicating hydrocephalis; 13. In noncommunicating hydrocephalus, the midline structure on the scintigram appeared thicker than the normal, because activity in the superior sagittal sinus was relatively high compared to the reduction of activity in the enlarged ventricles. In cases of very severe hydrocephalus, the basal ganglia was shown as a clear hot spot on the scintigram, because R. I. activity in the basal ganglia was relatively high compared to the reduction of R. I. activity in the enlarged ventricles. In cases of hydroencephalodysplasia, the midline structure on the scintigram shifted to the side opposite the dysplasia, as the result of pressure from a large CSF collection. In cases of cranium bifidum, the scintigram showed an elevation of the transverse sinus and the confluent sinus. (auth.)

OBJECTIVE Adult-onset hydrocephalus is not commonly discussed in the literature, especially regarding its demographic distribution. In contrast to pediatric hydrocephalus, which is related to a primary CSF pathway defect, its development in adults is often secondary to other pathologies. In this study, the authors investigated the epidemiology of adult-onset hydrocephalus as it pertains to different etiologies and in reference to age, sex, and race distributions. METHODS The authors retrospectively reviewed the clinical notes of 2001 patients with adult-onset hydrocephalus who presented to Louisiana State University Health Sciences Center within a 25-year span. Significant differences between the groups were analyzed by a chi-square test; p hydrocephalus in this population was 77 ± 30 per year, with a significant increase in incidence in the past decade (55 ± 3 [1990-2003] vs 102 ± 6 [2004-2015]; p Hydrocephalus in a majority of the patients had a vascular etiology (45.5%) or was a result of a tumor (30.2%). The incidence of hydrocephalus in different age groups varied according to various pathologies. The incidence was significantly higher in males with normal-pressure hydrocephalus (p = 0.03) or head injury (p = 0.01) and higher in females with pseudotumor cerebri (p hydrocephalus was significantly higher in Caucasian patients (p = 0.0002) than in those of any other race. CONCLUSIONS Knowledge of the demographic variations in adult-onset hydrocephalus is helpful in achieving better risk stratification and better managing the disease in patients. For general applicability, these results should be validated in a large-scale meta-analysis based on a national population database.

The objective of this study was to evaluate the method of prenatally estimating an appropriate clinical outcome in fetal hydrocephalus. Retrospective study, single institute (Osaka National Hospital). Hundred and seventeen cases with fetal hydrocephalus treated at Osaka National Hospital from 1992 to 2010 were analysed. Of the 117 cases analysed, 38% are diagnosed as isolated ventriculomegaly (IVM), 51% as other types of malformation (30 cases of myelomeningocele, 4 cases of holoprosencephaly, 4 of Dandy Walker syndrome, 10 of arachnoid cyst and 6 of encephalocele etc.) and 11% as secondary hydrocephalus. They are diagnosed between 17 and 40 weeks of gestation (average 27 weeks), 17% diagnosed between 17 and 21 weeks, 30% between 22 and 27 weeks and 53% after 28 weeks. With the exception of 9 aborted cases and 30 unknown cases too young to be evaluated or lost due to lack of follow-up, final outcome was analyzed in 78 cases. Of these 78 cases, 15% died in utero or after birth, 23% showed severe retardation, 17% moderate retardation, 26% mild retardation, and 19% showed good outcome. Long term consequences were mostly influenced by basic disease and accompanied anomalies. Hydrocephalus associated with arachnoid cyst, atresia of Monro, corpus callosum agenesis and hydrocephalus due to fetal intracranial hemorrhage are categorized in the good outcome group. On the other hand, holoprosencephaly, hydrocephalus associated with encephalocele, syndromic hydrocephalus and hydrocephalus due to fetal virus infection are categorized in the poor outcome group. In order to accurate diagnosis and proper counseling, establishment of diagnosis protocol and treatment policy for fetal hydrocephalus including not only fetal sonography, fetal MRI, toxoplasma, rubella, cytomegalovirus, herpes simplex (TORCH) screening test but also chromosomal and gene testing is required.

Reynolds, Fiona; Stanistreet, Debbi; Elton, Peter

2008-01-01

Background Several studies in the UK have suggested that women with learning disabilities may be less likely to receive cervical screening tests and a previous local study in had found that GPs considered screening unnecessary for women with learning disabilities. This study set out to ascertain whether women with learning disabilities are more likely to be ceased from a cervical screening programme than women without; and to examine the reasons given for ceasing women with learning disabilities. It was carried out in Bury, Heywood-and-Middleton and Rochdale. Methods Carried out using retrospective cohort study methods, women with learning disabilities were identified by Read code; and their cervical screening records were compared with the Call-and-Recall records of women without learning disabilities in order to examine their screening histories. Analysis was carried out using case-control methods – 1:2 (women with learning disabilities: women without learning disabilities), calculating odds ratios. Results 267 women's records were compared with the records of 534 women without learning disabilities. Women with learning disabilities had an odds ratio (OR) of 0.48 (Confidence Interval (CI) 0.38 – 0.58; X2: 72.227; p.value learning disabilities. Conclusion The reasons given for ceasing and/or not screening suggest that merely being coded as having a learning disability is not the sole reason for these actions. There are training needs among smear takers regarding appropriate reasons not to screen and providing screening for women with learning disabilities. PMID:18218106

Background: Hydrocephalus caused by unilateral foramen of Monro (FM) obstruction has been referred to in literature by many different terminologies. Precise terminology describing hydrocephalus confined to just one lateral ventricle has a very important prognostic value and determines whether or not the patient can be shunt free after an endoscopic procedure. Methods: Aiming to define the best term for unilateral FM obstruction, 19 terms were employed on PubMed database (http://www.ncbi.nlm.nih.gov/pubmed) as quoted phrases. Results: A total of 194 articles were found. Four patterns of hydrocephalus were discriminated as a result of our research term query and were divided by types for didactic purpose. Type A - partial dilation of the lateral ventricle; Type B - pure unilateral obstruction of the FM; Type C - previously shunted patients with secondary obstruction of the FM; and Type D - asymmetric lateral ventricles with patent FM. Conclusion: In unilateral FM obstruction hydrocephalus, an in-depth review on terminology application is critical to avoid mistakes that may compromise comparisons among different series. This terminology review suggests that Type B hydrocephalus, i.e., the hydrocephalus confined to just one lateral ventricle with no other sites of cerebrospinal fluid circulation blockage, are best described by the terms unilateral hydrocephalus (UH) and monoventricular hydrocephalus, the first being by far the most popular. Type A hydrocephalus is best represented in the literature by the terms uniloculated hydrocephalus and loculated ventricle; Type C hydrocephalus by the terms isolated lateral ventricle and isolated UH; and Type D hydrocephalus by the term asymmetric hydrocephalus.

A problem with inclusion in learning disability research.

Science.gov (United States)

McClimens, Alex; Allmark, Peter

2011-09-01

People with severe learning disability are particularly difficult to include in the research process. As a result, researchers may be tempted to focus on those with learning disability who can be included. The problem is exacerbated in this field as the political agenda of inclusion and involvement is driven by those people with learning disability who are the higher functioning. To overcome this we should first detach the notion of consent from ideas about autonomy and think instead of it as a way to avoid wronging others; this fits the original historical use of consent in research. This allows us to think in terms of including participants to the best of their abilities rather than in terms of a threshold of autonomy. Researchers could then use imaginative ways to include the least able and to ensure they are not wronged in research or by exclusion from it.

2017-01-18

Background People with learning disabilities experience significant inequalities in accessing healthcare. Legal frameworks, such as the Equality Act 2010, are intended to reduce such disparities in care, and require organisations to make 'reasonable adjustments' for people with disabilities, including learning disabilities. However, reasonable adjustments are often not clearly defined or adequately implemented in clinical practice. Aim To examine and synthesise the challenges in caring for people with learning disabilities to develop a framework for making reasonable adjustments for people with learning disabilities in hospital. This framework would assist ward staff in identifying and managing the challenges of delivering person-centred, safe and effective healthcare to people with learning disabilities in this setting. Method Fourth-generation evaluation, collaborative thematic analysis, reflection and a secondary analysis were used to develop a framework for making reasonable adjustments in the hospital setting. The authors attended ward manager and matron group meetings to collect their claims, concerns and issues, then conducted a collaborative thematic analysis with the group members to identify the main themes. Findings Four main themes were identified from the ward manager and matron group meetings: communication, choice-making, collaboration and coordination. These were used to develop the 4C framework for making reasonable adjustments for people with learning disabilities in hospital. Discussion The 4C framework has provided a basis for delivering person-centred care for people with learning disabilities. It has been used to inform training needs analyses, develop audit tools to review delivery of care that is adjusted appropriately to the individual patient; and to develop competencies for learning disability champions. The most significant benefit of the 4C framework has been in helping to evaluate and resolve practice-based scenarios. Conclusion Use of

2018-05-01

We used longitudinal data from Washington State to investigate the relationships among career and technical education (CTE) enrollment, inclusion in general education, and high school and postsecondary outcomes for students with learning disabilities. We replicated earlier findings that students with learning disabilities who were enrolled in a "concentration" of CTE courses had higher rates of employment after graduation than observably similar students with learning disabilities who were enrolled in fewer CTE courses. We also found that students with learning disabilities who spent more time in general education classrooms in high school had higher rates of on-time graduation, college attendance, and employment than observably similar students with learning disabilities who spent less time in general education classrooms in these grades.

New concept of the pathogenesis and therapeutic orientation of acquired communicating hydrocephalus.

Science.gov (United States)

Xu, Hao

2016-09-01

Hydrocephalus is a common medical condition characterized by abnormalities in the secretion, circulation and absorption of cerebrospinal fluid (CSF), resulting in ventricle dilatation. For the communicating hydrocephalus, without etiological treatment, its pathogenesis has been considered as a research emphasis. Many factors can damage the CSF system and trigger communicating hydrocephalus, including tumor surgery and hydrocephalus neurological diseases, such as brain trauma, infection, ICH and SAH. But according to our clinical experience, a big proportion of patients do not develop hydrocephalus. That is because the absorbing ability of CSF can compensate within a certain range. If the damage exceeds that range, hydrocephalus will occur. Once it occurs, it is not likely to be reversed, so a shunt surgery is always needed. Therefore, we believe that our orientation could transform the treatment of patient who has already showed hydrocephalus symptoms to the prevention of the occurrence in the patient with high risk of hydrocephalus. Based on the hypothesis above, we first divide the process of hydrocephalus into three stages and we believe that hydrocephalus are possible be reversed or halted in stage 1 and 2. The new concept of the pathogenesis in hydrocephalus will enrich our understanding and provide new insights to the therapeutic orientation. In conclusion, the future research direction should be the prevention of hydrocephalus, which should take a long period from the immediate occurrence of brain injury to several months or even years after the injury.

Lew, Sean M.; Matthews, Anne E.; Hartman, Adam L.; Haranhalli, Neil

2012-01-01

SUMMARY Purpose Hemispherectomy surgery for medically intractable epilepsy is known to cause hydrocephalus in a subset of patients. Existing data regarding the incidence of, and risk factors for developing, post-hemispherectomy hydrocephalus has been limited by the relatively small number of cases performed by any single center. Our goal was to better understand this phenomenon and to identify risk factors that may predispose patients to developing hydrocephalus after hemispherectomy surgery. Methods Fifteen pediatric epilepsy centers participated in this study. A retrospective chart review was performed on all available patients who had hemispherectomy surgery. Data collected included surgical techniques, etiology of seizures, prior brain surgery, symptoms and signs of hydrocephalus, timing of shunt placement and basic demographics. Key findings Data were collected from 736 patients who underwent hemispherectomy surgery between 1986 and 2011. Forty-six patients had pre-existing shunted hydrocephalus and were excluded from analysis, yielding 690 patients for this study. One hundred sixty-two patients (23%) required hydrocephalus treatment. The timing of hydrocephalus ranged from the immediate post-operative period to 8.5 years after surgery, with 43 patients (27%) receiving shunts more than 90 days after surgery. Multivariate regression analysis revealed anatomic hemispherectomies (OR 4.1, phydrocephalus. There was a trend towards significance for the use of hemostatic agents (O.R. 2.2, p=0.07) and the involvement of basal ganglia or thalamus in the resection (O.R. 2.2, p=0.08) as risk factors. Significance Hydrocephalus is a common sequela of hemispherectomy surgery. Surgical technique and prior brain surgery influence the occurrence of post-hemispherectomy hydrocephalus. A significant portion of patients develop hydrocephalus on a delayed basis, indicating the need for long-term surveillance. PMID:23106378

1988-01-01

In six young patients presenting with raised intracranial pressure during the period of a year, CT revealed the presence of hydrocephalus, but not the cause. Magnetic Resonance Imaging not only showed the site and nature of the obstructing lesion, but also detected additional clinically silent spinal cord tumors in five of the patients. The place of MRI in the diagnosis of diseases involving the region of the cranio-cervical junction and in the elucidation of 'unexplained hydrocephalus' is considered. (orig.)

Sylvian fissure and sulcal enlargement is generally perceived as indicative of cortical atrophy and has been used by surgeons in cases of suspected hydrocephalus as a criterion for exclusion from ventricular shunting procedure. The authors have observed sylvian fissure collapse following ventricular shunting in several patients with communicating hydrocephalus (CH). The purpose of this study was to determine the incidence of this finding in patients with CH. The pre- and postshunt CT and MR images of 30 patients with communicating hydrocephalus were reviewed. As anticipated, after shunting a diminution in caliber of the lateral ventricle bodies, temporal horns, and third ventricle occurred in a majority of cases. However, sulcal width paradoxically decreased in 13% of cases after shunt, and sylvian fissure size decreased in seven patients after shunt (23%). In summary, large sylvian fissures and focally dilated sulci do not rule out the presence of hydrocephalus and may in fact act as cerebrospinal fluid reservoirs in cases of obstruction higher along the cerebral convexities

Post-hemorrhagic hydrocephalus (PHH), also referred to as progressive ventricular dilatation, is caused by disturbances in cerebrospinal fluid (CSF) flow or absorption following hemorrhage in the brain. As one of the most serious complications of neonatal/adult intraventricular hemorrhage (IVH), subarachnoid hemorrhage (SAH), and traumatic brain injury (TBI), PHH is associated with increased morbidity and disability of these events. Common sequelae of PHH include neurocognitive impairment, motor dysfunction, and growth impairment. Non-surgical measures to reduce increased intracranial pressure (ICP) in PHH have shown little success and most patients will ultimately require surgical management, such as external ventricular drainage and shunting which mostly by inserting a CSF drainage shunt. Unfortunately, shunt complications are common and the optimum time for intervention is unclear. To date, there remains no comprehensive strategy for PHH management and it becomes imperative that to explore new therapeutic targets and methods for PHH. Over past decades, increasing evidence have indicated that hemorrhage-derived blood and subsequent metabolic products may play a key role in the development of IVH-, SAH- and TBI-associated PHH. Several intervention strategies have recently been evaluated and cross-referenced. In this review, we summarized and discussed the common aspects of hydrocephalus following IVH, SAH and TBI, relevant experimental animal models, clinical translation of in vivo experiments, and potential preventive and therapeutic targets for PHH.

Hydrocephalus-history of surgical treatment over the centuries

Directory of Open Access Journals (Sweden)

2012-01-01

Full Text Available To trace the history of the treatment of hydrocephalus is to document the parallel development of medicine as a whole; when one reviews the treatment of hydrocephalus, the integral relationship between basic science and therapy is reaffirmed. The treatment of hydrocephalus, over the centuries, underwent three stages of evolution. Prior to the late 19 th century, treatment for 'water on the brain' involved more observation than intervention. During antiquity, middle ages and renaissance, hydrocephalus was not understood. Medical treatment was useless; surgery was hopeless. The second stage extends from the 19th century to the end of the first half of the 20 th century. Cerebrospinal fluid circulation was now understood; surgery however, remained inefficient, but some patients survived with arrested hydrocephalus. The third stage begins in the nineteen fifties with the development of silicone shunts with a valve. Surgery transforms the prognosis of hydrocephalus, but the number of post-operative complications creates new problems. The different attempts that have been made during these past two decades to solve these problems are reviewed. They have resulted in a reduction of the mechanical and infectious complications. CSF over drainage has been minimized. Percutaneous ventriculo-cisternostomies have in some cases replaced shunts. In the future, to improve outcome in these hydrocephalics, surgery, when indicated, should be performed as early as possible. Knowledge and prevention of the causes of hydrocephalus should be developed. As we progress further in this new millennium, it is appropriate to reflect on the past understanding and treatment of this disorder, review strategies to curb this disease process, and consider therapies and possibly cures that will be available in the future.

An adult learning perspective on disability and microfinance: The case of Katureebe.

Science.gov (United States)

Nuwagaba, Ephraim L; Rule, Peter N

2016-01-01

Despite Uganda's progress in promoting affirmative action for persons with disabilities and its strategy of using microfinance to fight poverty, access to microfinance services by persons with disabilities is still problematic due to barriers, characterised by discrepancies between policies and practices. Regarding education, the affirmative action in favour of learners with disabilities has not translated into actual learning opportunities due to personal and environmental barriers. The study on which this article is based investigated the non-formal and informal adult learning practices regarding microfinance that persons with disabilities engaged in. This article seeks to illuminate the barriers that a person with a visual impairment encountered while learning about and engaging with microfinance and the strategies that he developed to overcome them. This was a case study, framed within the social model of disability and critical research paradigm. Data were collected through in-depth interviews of a person with visual impairment and observations of the environment in which adult learning and engagement with Savings and Credit Cooperative Organisations (SACCOs) occurred. Findings indicate that the person with a visual disability faced barriers to learning about microfinance services. He experienced barriers in an integrated manner and developed strategies to overcome these barriers. The barriers and strategies are theorised using the social model of disability. The case of a person with visual impairment suggests that persons with disabilities face multiple barriers regarding microfinance, including social, psychological and educational. However, his own agency and attitudes were also of importance as they influenced his learning. Viewing these barriers as blockades can lead to non-participation in learning and engagement with microfinance whereas viewing them as surmountable hurdles can potentially motivate participants to succeed in learning about and engaging

Full Text Available School failure is one of the more complex, more difficult and unfortunately frequent problem that modern school meets. Many factors can cause school failure, such as: child development characteristics, family and school-originated factors. The purpose of the research is analysis of the specific learning problems in students with a mild intellectual disability. For our research we used ACADIA test, which contains 13 subtests for assessing the overall individual functioning. The research involved 144 students. We divided the sample into two groups, children with intellectual disability (our target group and control group. We found that generally all students with the intellectual disability have special learning problems. According to individual subtests analysis we concluded that the ability for visual association is best developed among these students while on the subtest for auditory memory they achieved worse results. With the analysis of the control group we found that 13.75% of the students have special learning problems.

Several studies have investigated the incidence and risk factors of hydrocephalus after decompressive craniectomy (DC) for malignant hemispheric cerebral infarction. However, the results are controversial. Therefore, the following is a retrospective cohort study to determine the incidence and risk factors of hydrocephalus after DC for malignant hemispheric cerebral infarction. From January 2004 to June 2014, patients at two medical centres in south-west China, who underwent DC for malignant hemispheric cerebral infarction, were included. The patients' clinical and radiologic findings were retrospectively reviewed. A chi-square test, Mann-Whitney U-test and logistic regression model were used to identify the risk factors. A total of 128 patients were included in the study. The incidence of ventriculomegaly and shunt-dependent hydrocephalus were 42.2% (54/128) and 14.8% (19/128), respectively. Lower preoperative Glasgow Coma Scale (GCS) score and presence of subarachnoid haemorrhage (SAH) were factors significantly associated with the development of post-operative hydrocephalus after DC. Cerebral infarction patients receiving DC have a moderate tendency to suffer from post-operative hydrocephalus. A poor GCS score and the presence of SAH were significantly associated with the development of hydrocephalus after DC.

Teacher recommended academic and student engagement strategies for learning disabled students: A qualitative study

Nwachukwu, Bethel C.

There has been a push towards the education of students with Learning Disabilities in inclusive educational settings with their non-disabled peers. Zigmond (2003) stated that it is not the placement of students with disabilities in general education setting alone that would guarantee their successes; instead, the strategies teachers use to ensure that these children are being engaged and learning will enable them become successful. Despite the fact that there are several bodies of research on effective teaching of students with learning disabilities, special education teachers continue to have difficulties concerning the appropriate strategies for promoting student engagement and improving learning for students with learning disabilities placed in inclusive educational settings (Zigmond, 2003). This qualitative study interviewed and collected data from fifteen high performing special education teachers who were employed in a Southern state elementary school district to uncover the strategies they have found useful in their attempts to promote student engagement and attempts to improve student achievement for students with learning disabilities placed in inclusive educational settings. The study uncovered strategies for promoting engagement and improving learning outcomes for students with learning disabilities placed in inclusive classrooms. The findings showed that in order to actually reach the students with learning disabilities, special education teachers must go the extra miles by building rapport with the school communities, possess good classroom management skills, and become student advocates.

Decompressive craniectomy (DC) may be necessary to save the lives of patients suffering from intracranial hypertension. However, this procedure is not complication-free. Its two main complications are hydrocephalus and the sinking skin-flap syndrome (SSFS). The radiological findings and the clinical evaluation may be not enough to decide when and/or how to treat hydrocephalus in a decompressed patient. SSFS and hydrocephalus may be not unrelated. In fact, a patient affected by hydrocephalus, after the ventriculo-peritoneal shunt, can develop SSFS; on the other hand, SSFS per se can cause hydrocephalus. Treating hydrocephalus in decompressed patients can be challenging. Radiological findings and clinical evaluation may not be enough to define the most appropriate therapeutic strategy. Cerebrospinal fluid (CSF) dynamics and metabolic evaluations can represent important diagnostic tools for assessing the need of a CSF shunt in patients with a poor baseline neurologic status. Based on our experience, we propose a flow chart for treating decompressed patients affected by ventriculomegaly.

This paper will primarily examine four concepts: emotional learning disabilities, adolescence, self-esteem, and the social-psychological concept of "significant others." Problems of definition will be discussed, with a literature review, and an attempt will be made to integrate all four of the above-mentioned concepts. The emphasis will be in applying a sociological perspective to an educational and growing problem: how do we (sic) educate students with some type of learning disability? What, if any, extra-curricular factors potentially affect in school learning behavior(s) of adolescents?

Ruptured Massa Intermedia Secondary to Hydrocephalus.

El Damaty, Ahmed; Langner, Soenke; Schroeder, Henry W S

2017-01-01

We report a case of ruptured massa intermedia (MI) as a sequela of hydrocephalus. A single case report is presented describing the sequelae of tumor bed hematoma after a posterior fossa hemangioblastoma resection in which the patient bled 3 days after surgery, resulting in secondary hydrocephalus and subsequently dilatation of the third ventricle, which resulted in rupture of the MI. The patient was managed on emergency basis with an external ventricular drain then endoscopically with a third ventriculostomy and clot extraction. Absent MI is not uncommon in hydrocephalic patients, and it is assumed to be the result of rupture from acute dilatation of the third ventricle. Our case report proves this assumption and documents the presence and absence of the MI before and after developing hydrocephalus. Copyright © 2016 Elsevier Inc. All rights reserved.

2017-03-01

To conduct a user-friendly questionnaire survey of the oral health and service needs of adults with learning disabilities. Researchers collaborated with local self-advocacy services to develop a questionnaire adapted from one used in a regional postal survey. The questionnaire, which covered dental status, oral health and dental services use, was sent to a random sample of people from the learning disability case register. Of 2,000 questionnaires mailed, 117 were returned undelivered and 625 were completed (response rate 31.3%). The self-reported dental status of people with learning disabilities appeared similar to that of the 2008 postal survey of the general population in Sheffield. The major difference in dental status was 11.5% of people with learning disabilities wore upper dentures and 7.2% wore lower dentures, compared to 21.2% and 12.1% of the general population in Sheffield. Using the case register as a recruitment instrument may have excluded people with learning disabilities not registered. Time and finances only permitted one mailing. Analysis on the basis of deprivation could not be conducted. Contrary to current practice, it is possible to include people with learning disabilities in oral health surveys. A multidisciplinary team was essential for enabling the progression and implementation of inclusive research and for people with learning disabilities and their supporters to engage meaningfully. This level of collaboration appears necessary if we are committed to ensuring that people with learning disabilities and their supporters are made visible to policy and decision-makers.

Vachha Behroze

2005-11-01

Full Text Available Abstract Background Selective learning is the ability to select items of relevance from among less important items. Limited evidence exists regarding the efficiency with which children with spina bifida-myelomeningocele and shunted hydrocephalus (SB/SH are able to learn information. This report describes initial data related to components of learning and metacognitive skills in children with SB/SH. Methods Twenty six children with SB/SH and 26 controls (age: 7 – 16 y with average intelligence, and monolingual English-speaking backgrounds participated in the study. Exclusion criteria for the SB/SH group were: prior history of shunt infection, history of seizure or shunt malfunction within the previous three months, prior diagnoses of attention disorders and/or clinical depression. Children were presented lists of words with equal exemplars each of two distinct semantic categories (e.g. fruits, animals, and told to make as high a score as possible by learning the words. The value of the words was designated by category membership (e.g. animals = low value; fruits = high value. The total number of words learned across three learning trials was used to determine memory span. Selective learning efficiency (SLE was computed as the efficiency with which items of greater value were selectively learned across three trials. Results Children with SB/SH did worse than controls on memory span (P Conclusion Success in school is often dependent on the ability to recall important facts selectively and ignore less important information. Children with SB/SH in our study had a poor memory span and were unable to monitor and report an efficient and workable metacognitive strategy required to remember a list of words. Preliminary findings may begin to explain our previous clinical and research findings wherein children with SB/SH often focus on extraneous details, but demonstrate difficulty remembering the main gist of a story/event.

Full Text Available Abstract Background Several studies in the UK have suggested that women with learning disabilities may be less likely to receive cervical screening tests and a previous local study in had found that GPs considered screening unnecessary for women with learning disabilities. This study set out to ascertain whether women with learning disabilities are more likely to be ceased from a cervical screening programme than women without; and to examine the reasons given for ceasing women with learning disabilities. It was carried out in Bury, Heywood-and-Middleton and Rochdale. Methods Carried out using retrospective cohort study methods, women with learning disabilities were identified by Read code; and their cervical screening records were compared with the Call-and-Recall records of women without learning disabilities in order to examine their screening histories. Analysis was carried out using case-control methods – 1:2 (women with learning disabilities: women without learning disabilities, calculating odds ratios. Results 267 women's records were compared with the records of 534 women without learning disabilities. Women with learning disabilities had an odds ratio (OR of 0.48 (Confidence Interval (CI 0.38 – 0.58; X2: 72.227; p.value X2: 24.236; p.value X2: 286.341; p.value Conclusion The reasons given for ceasing and/or not screening suggest that merely being coded as having a learning disability is not the sole reason for these actions. There are training needs among smear takers regarding appropriate reasons not to screen and providing screening for women with learning disabilities.

An exploration of equitable science teaching practices for students with learning disabilities

Science.gov (United States)

Morales, Marlene

In this study, a mixed methods approach was used to gather descriptive exploratory information regarding the teaching of science to middle grades students with learning disabilities within a general education classroom. The purpose of this study was to examine teachers' beliefs and their practices concerning providing equitable opportunities for students with learning disabilities in a general education science classroom. Equitable science teaching practices take into account each student's differences and uses those differences to inform instructional decisions and tailor teaching practices based on the student's individualized learning needs. Students with learning disabilities are similar to their non-disabled peers; however, they need some differentiation in instruction to perform to their highest potential achievement levels (Finson, Ormsbee, & Jensen, 2011). In the quantitative phase, the purpose of the study was to identify patterns in the beliefs of middle grades science teachers about the inclusion of students with learning disabilities in the general education classroom. In the qualitative phase, the purpose of the study was to present examples of instruction in the classrooms of science education reform-oriented middle grades science teachers. The quantitative phase of the study collected data from 274 sixth through eighth grade teachers in the State of Florida during the 2007--2008 school year using The Teaching Science to Students with Learning Disabilities Inventory. Overall, the quantitative findings revealed that middle grades science teachers held positive beliefs about the inclusion of students with learning disabilities in the general education science classroom. The qualitative phase collected data from multiple sources (interviews, classroom observations, and artifacts) to develop two case studies of reform-oriented middle grades science teachers who were expected to provide equitable science teaching practices.

Karande, Sunil; Sholapurwala, Rukhshana; Kulkarni, Madhuri

2011-07-01

Specific learning disability (dyslexia, dysgraphia, and dyscalculia) afflicts 5-15% of school-going children. Over the last decade; awareness about this invisible handicap has grown in India. However, much needs to be done to ensure that each afflicted child gets an opportunity to achieve his or her full academic potential in regular mainstream schools. In order to achieve this ideal scenario, all regular classroom teachers should be sensitized to suspect, and trained to screen for this disability when the child is in primary school. School managements should become proactive to set up resource rooms and employ special educators to ensure that these children receive regular and affordable remedial education; and be diligent in ensuring that these children get the mandatory provisions both during school and board examinations. Once specific learning disability is recognized as a disability by the Government of India, these children with the backing of the Right to Education Act, would be able to benefit significantly.

Developing a service improvement initiative for people with learning disabilities in hospice settings.

People with learning disabilities are often marginalised in healthcare, including in hospice settings, and as a result may not receive effective end of life care. Research in hospice settings has identified that many staff lack confidence, skills and knowledge in caring for people with learning disabilities, which can have a negative effect on the care these individuals receive. To address these issues, the author has proposed a service improvement initiative, which she developed as part of her learning disability nursing degree programme. This proposed initiative aimed to enhance end of life care for people with learning disabilities through the implementation of a community learning disability link nurse in the hospice setting. ©2018 RCN Publishing Company Ltd.

Kumar, Vikas; Bodeliwala, Shaam; Singh, Daljit

2017-08-01

The best management of hydrocephalus is still controversial in the twenty-first century. Shunt treatment for hydrocephalus is the most common procedure performed in neurosurgical practice and is associated with the highest complications rate. But during the last 2 decades, the treatment of hydrocephalus has improved with better shunt devices available today, increased facilities for investigations and newer approaches like endoscopic third ventriculostomy. The recent advances in development of better endoscopes have provided the patient and treating doctor with an option for an alternative surgery for treatment of hydrocephalus.

The risk of hydrocephalus in end-stage renal disease (ESRD) patients on dialysis has not been studied in depth. Using Taiwan National Health Insurance claims data, we identified 29 684 incident ESRD patients from 2000 to 2010, including 10 030 peritoneal dialysis (PD) patients and 19 654 hemodialysis (HD) patients. The control cohort consisted of 118 736 people randomly selected from those without kidney disease, frequency matched with ESRD patients by age, sex and index year. We also established propensity score-matched cohorts with 10 014 PD and 10 014 HD patients. The incidence rates and hazard ratios (HRs) of hydrocephalus were calculated until the end of 2011. Incidence rates of hydrocephalus were greater in HD and PD patients than in controls (8.44 and 11.0 versus 4.11 per 10 000 person-years, respectively), with an adjusted HR of 1.86 [95% confidence interval (CI) 1.43-2.41] for all ESRD patients compared with controls. A higher proportion of hydrocephalus patients underwent surgical bypass to relieve hydrocephalus in ESRD patients than controls, 40.7% (46/113) versus 24.5% (67/273), with an adjusted odds ratio of 2.11 (95% CI 1.33-3.36). Compared with controls, the adjusted HRs of communicating hydrocephalus for HD and PD patients were 1.77 (95% CI 1.22-2.55) and 2.51 (95% CI 1.61-3.89), respectively. The propensity score-matched analysis showed an HR of 0.72 (95% CI 0.42-1.23) for hydrocephalus in HD patients compared with PD patients. Patients with ESRD are at an increased risk of hydrocephalus. The risk difference between HD and PD patients is not significant. © The Author 2016. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

Vertebrobasilar dolichoectasia induced hydrocephalus: the water-hammer effect

Directory of Open Access Journals (Sweden)

Vaso Zisimopoulou

2015-05-01

Full Text Available Vertebrobasilar dolichoectasia is a clinical entity associated rarely with obstructive hydrocephalus. We present a 48-year old male with a profound dilatation of the ventricular system due to a dolichoectatic basilar artery, as appeared in imaging studies. The patient suffered from longstanding hydrocephalus and presenile dementia. The underlying mechanism for obstructive hydrocephalus due to vertebrobasilar dolichoectasia is considered to be both a water-hammer effect and a direct compression of adjacent structures. We suggest prompt surgical intervention upon diagnosis as a first choice treatment in order to avoid further complications.

Mechanisms of hydrocephalus in cerebral cysticercosis: implications for therapy

1983-01-01

Patients with hydrocephalus secondary to cerebral cysticercosis are a highly heterogeneous group. The mechanisms of hydrocephalus in these patients are multiple. Intraventricular cysts may be found in the 3rd and 4th ventricles, the sylvian aqueduct, and the foramen of Monro. Intraventricular cysts can be suspected when the 3rd and 4th ventricles or aqueduct remain enlarged despite shunting. Intraventricular contrast medium demonstrates the presence of the parasites. The intraventricular cysts should be removed surgically. Hydrocephalus due to cisternal cysticercosis can be diagnosed by isotope cisternography. These patients should receive shunts, but the long term prognosis is probably poor. Guidelines for the management of hydrocephalus due to cysticercosis are suggested

Patients with hydrocephalus secondary to cerebral cysticercosis are a highly heterogeneous group. The mechanisms of hydrocephalus in these patients are multiple. Intraventricular cysts may be found in the 3rd and 4th ventricles, the sylvian aqueduct, and the foramen of Monro. Intraventricular cysts can be suspected when the 3rd and 4th ventricles or aqueduct remain enlarged despite shunting. Intraventricular contrast medium demonstrates the presence of the parasites. The intraventricular cysts should be removed surgically. Hydrocephalus due to cisternal cysticercosis can be diagnosed by isotope cisternography. These patients should receive shunts, but the long term prognosis is probably poor. Guidelines for the management of hydrocephalus due to cysticercosis are suggested.

Blair, Jim

2011-12-01

Health inequalities start early in life for people with learning disabilities. In the UK, they can arise from various barriers that people experience when trying to access care that should be appropriate, timely and effective. Inequalities in health care are likely to result in many NHS organisations breaching their legal responsibilities, as outlined in the Disability Discrimination Acts 1995 and 2005, the Equality Act 2010 and the Mental Capacity Act 2005 (Emerson and Baines 2010). This article seeks to help nurses, healthcare professionals and hospital managers ensure that better services are delivered by encouraging them to explore how reasonable adjustments can improve outcomes for people with learning disabilities.

Prenatal diagnosis and perinatal management of congenital hydrocephalus using MRI

International Nuclear Information System (INIS)

Hamada, Hiromi; Koresawa, Mitsuhiko; Kubo, Takeshi

1990-01-01

We studied congenital hydrocephalus in 14 patients who were diagnosed prenatally. As a result, we obtained the following insights concerning the prenatal diagnosis by MRI (magnetic resonance imaging) and perinatal management of congenital hydrocephalus. Accurate diagnosis of congenital hydrocephalus was impossible prenatally by two-dimensional ultrasonography or computed tomography alone in some patients. MRI was useful for accurate prenatal diagnosis. Problem of MRI in prenatal diagnosis included deterioration of the image by fetal movements and safety concern over the fetus. The cause of hydrocephalus, complicated anomaly, cerebral cortical thickness, and gestational age must be considered in the perinatal management of congenital hydrocephalus. There appeared to be a chance of recovery to a certain extent from thinning of cerebral cortex by decompression in a patient in whom dilation of cerebral ventricles progressed rapidly. (author)

Involving people with learning disabilities in nurse education: towards an inclusive approach.

Bollard, Martin; Lahiff, John; Parkes, Neville

2012-02-01

There is limited evidence that explores how to effectively include people with learning disabilities in nurse education in the U.K. The majority of reported work relates to mental health nursing and social work training (Morgan and Jones, 2009). This paper specifically reports on the processes and activities undertaken by the authors with people with learning disabilities in the development of a new BSc learning disability nursing programme, a specific branch of nursing in the U.K. In doing so, findings and discussion from two separate projects involving students and people with learning disabilities will be integrated into the paper. EPICURE (Engagement, Processing, Interpretation, Critique, Usefulness, Relevance and Ethics (Stige et al. 2009) is adopted as a qualitative framework throughout the paper to evaluate the reported work that took place between September 2006 and October 2010. Suggestions are therefore made regarding the benefits and challenges of striving towards an inclusive approach to user involvement in nurse education, with particular reference to learning disability. The work presented in the paper demonstrates how through careful involvement of this population, deeper learning opportunities for all nursing students can be created. Copyright © 2011 Elsevier Ltd.

Wang, Qiang-Ping; Ma, Jun-Peng; Zhou, Zhang-Ming; You, Chao

2016-01-01

Objective: To evaluate the correlation between the distance of craniectomy from the midline and hydrocephalus after DC. Methods: The following electronic databases were searched from their inception to June 2015: Cochrane Library, MEDLINE, Science Direct, EMBASE, Scopus, Google Scholar, the Chinese Biomedical Database (CBM), and the Chinese National Knowledge Infrastructure (CNKI). All randomized clinical trials, prospective cohort, retrospective observational cohort, and case-control studies investigating the relationship between distance of craniectomy from the midline and hydrocephalus after DC were enrolled. The Cochrane Collaboration’s software RevMan 5.3 was used for meta-analysis. Results: Six retrospective cohort studies involving 462 participants were included. Pooled analysis of 4 studies suggested that craniectomy close to the midline (hydrocephalus (odds ratio [OR] = 3.61, 95% confidence interval [CI]: 1.3 - 9.97, p=0.01). However, meta-analysis of 4 studies did not find statistical differences when comparing the distance of craniectomy from the midline in the hydrocephalus group and that in the non-hydrocephalus group (OR = −0.14, 95% CI: −0.44 - 0.15, p=0.34). Conclusions: Available evidence was insufficient to support the theory that craniectomy close to the midline increases the risk of developing hydrocephalus after DC. Well-conducted randomized clinical trials are required to verify this issue. PMID:26818161

Pediatric hydrocephalus outcomes: a review

2012-08-01

Full Text Available Abstract The outcome of pediatric hydrocephalus, including surgical complications, neurological sequelae and academic achievement, has been the matter of many studies. However, much uncertainty remains, regarding the very long-term and social outcome, and the determinants of complications and clinical outcome. In this paper, we review the different facets of outcome, including surgical outcome (shunt failure, infection and independence, and complications of endoscopy, clinical outcome (neurological, sensory, cognitive sequels, epilepsy, schooling and social integration. We then provide a brief review of the English-language literature and highlighting selected studies that provide information on the outcome and sequelae of pediatric hydrocephalus, and the impact of predictive variables on outcome. Mortality caused by hydrocephalus and its treatments is between 0 and 3%, depending on the duration of follow-up. Shunt event-free survival (EFS is about 70% at one year and 40% at ten years. The EFS after endoscopic third ventriculostomy (ETV appears better but likely benefits from selection bias and long-term figures are not available. Shunt infection affects between 5 and 8% of surgeries, and 15 to 30% of patients according to the duration of follow-up. Shunt independence can be achieved in 3 to 9% of patients, but the definition of this varies. Broad variations in the prevalence of cognitive sequelae, affecting 12 to 50% of children, and difficulties at school, affecting between 20 and 60%, attest of disparities among studies in their clinical evaluation. Epilepsy, affecting 6 to 30% of patients, has a serious impact on outcome. In adulthood, social integration is poor in a substantial number of patients but data are sparse. Few controlled prospective studies exist regarding hydrocephalus outcomes; in their absence, largely retrospective studies must be used to evaluate the long-term consequences of hydrocephalus and its treatments.

Yamada, S; Ishikawa, M; Yamamoto, K

2016-07-01

CSF volumes in the basal cistern and Sylvian fissure are increased in both idiopathic normal pressure hydrocephalus and Alzheimer disease, though the differences in these volumes in idiopathic normal pressure hydrocephalus and Alzheimer disease have not been well-described. Using CSF segmentation and volume quantification, we compared the distribution of CSF in idiopathic normal pressure hydrocephalus and Alzheimer disease. CSF volumes were extracted from T2-weighted 3D spin-echo sequences on 3T MR imaging and quantified semi-automatically. We compared the volumes and ratios of the ventricles and subarachnoid spaces after classification in 30 patients diagnosed with idiopathic normal pressure hydrocephalus, 10 with concurrent idiopathic normal pressure hydrocephalus and Alzheimer disease, 18 with Alzheimer disease, and 26 control subjects 60 years of age or older. Brain to ventricle ratios at the anterior and posterior commissure levels and 3D volumetric convexity cistern to ventricle ratios were useful indices for the differential diagnosis of idiopathic normal pressure hydrocephalus or idiopathic normal pressure hydrocephalus with Alzheimer disease from Alzheimer disease, similar to the z-Evans index and callosal angle. The most distinctive characteristics of the CSF distribution in idiopathic normal pressure hydrocephalus were small convexity subarachnoid spaces and the large volume of the basal cistern and Sylvian fissure. The distribution of the subarachnoid spaces in the idiopathic normal pressure hydrocephalus with Alzheimer disease group was the most deformed among these 3 groups, though the mean ventricular volume of the idiopathic normal pressure hydrocephalus with Alzheimer disease group was intermediate between that of the idiopathic normal pressure hydrocephalus and Alzheimer disease groups. The z-axial expansion of the lateral ventricle and compression of the brain just above the ventricle were the common findings in the parameters for differentiating

Cancer incidence among people with learning disabilities is rising. There have been no published studies of the needs and experiences of people with learning disabilities and cancer, from their own perspective. To provide insight into the experiences and needs of people with learning disabilities who have cancer. Prospective qualitative study, using ethnographic methods. Participants' homes, hospitals, nursing homes, and hospices in London and surrounding areas. The participants were 13 people with learning disabilities ranging from mild to severe, who had a cancer diagnosis. The main method of data collection was participant observation (over 250 hours). The median length of participation was 7 months. Participants' cancer experiences were shaped by their previous experience of life, which included deprivation, loneliness, and a lack of autonomy and power. They depended on others to negotiate contact with the outside world, including the healthcare system. This could lead to delayed cancer diagnosis and a lack of treatment options being offered. Most participants were not helped to understand their illness and its implications. Doctors did not make an assessment of capacity, but relied on carers' opinions. Urgent action is warranted by findings of late diagnosis, possible discrimination around treatment options, and lack of patient involvement and assessment of capacity in decision making. There are significant gaps in knowledge and training among most health professionals, leading to disengaged services that are unaware of the physical, emotional, and practical needs of people with learning disabilities, and their carers.

Experimental hydrocephalus following mechanical increment of intraventricular pulse pressure.

Science.gov (United States)

Di Rocco, C; Pettorossi, V E; Caldarelli, M; Mancinelli, R; Velardi, F

1977-11-15

Experimental hydrocephalus has been induced in lambs by artificial increase of the amplitude of intraventricular cerebrospinal fluid (CSF) oscillations related to arterial pulsations, without concomitant changes of the mean CSF-pressure. The characteristics of this hydrocephalus demonstrate that the intraventricular CSF-pulsations can play a role in the genesis of ventricular dilation. Such a method may be used to produce an original model of hydrocephalus independent of changes of CSF-circulation or absorption.

Intraventricular hemorrhage (IVH) is a cause of significant morbidity and mortality and is an independent predictor of a worse outcome in intracerebral hemorrhage (ICH) and germinal matrix hemorrhage (GMH). IVH may result in both injuries to the brain as well as hydrocephalus. This paper reviews evidence on the mechanisms and potential treatments for IVH-induced hydrocephalus. One frequently cited theory to explain hydrocephalus after IVH involves obliteration of the arachnoid villi by microt...

Communicating hydrocephalus due to cerebral venous sinus thrombosis treated with ventriculoperitoneal shunt

Directory of Open Access Journals (Sweden)

Rahul T Chakor

2012-01-01

Full Text Available Cerebral venous sinus thrombosis (CVT is a rare cerebrovascular disease with variable presentation. CVT rarely causes hydrocephalus. Communicating hydrocephalus due to CVT is extremely rare. We describe a patient of CVT presenting with chronic headache and communicating hydrocephalus. The patient was successfully treated with ventriculoperitoneal (VP shunt. A 40 year old man presented with moderate to severe headache since six months and progressive visual loss since two months. Head Computed tomogram showed mild hydrocephalus without obstruction. Lumbar puncture (LP demonstrated elevated pressure but was otherwise normal. Magnetic resonance venogram showed extensive CVT. Repeated CSF drainage and thecoperitoneal shunt did not relieve the severe headache hence a VP shunt was placed. Post shunt headache subsided with resolution of hydrocephalus. CVT can present as communicating hydrocephalus. Gradual reduction of intra-ventricular pressure by repeated LPs followed by VP shunt can safely treat hydrocephalus due to CVT.

To examine the role of learning disability liaison nurses in facilitating reasonable and achievable adjustments to support access to general hospital services for people with learning disabilities. Mixed methods study involving four health boards in Scotland with established Learning Disability Liaison Nurses (LDLN) Services. Quantitative data of all liaison nursing referrals over 18 months and qualitative data collected from stakeholders with experience of using the liaison services within the previous 3-6 months. Six liaison nurses collected quantitative data of 323 referrals and activity between September 2008-March 2010. Interviews and focus groups were held with 85 participants included adults with learning disabilities (n = 5), carers (n = 16), primary care (n = 39), general hospital (n = 19) and liaison nurses (n = 6). Facilitating reasonable and achievable adjustments was an important element of the LDLNs' role and focussed on access to information; adjustments to care; appropriate environment of care; ensuring equitable care; identifying patient need; meeting patient needs; and specialist tools/resources. Ensuring that reasonable adjustments are made in the general hospital setting promotes person-centred care and equal health outcomes for people with a learning disability. This view accords with 'Getting it right' charter produced by the UK Charity Mencap which argues that healthcare professionals need support, encouragement and guidance to make reasonable adjustments for this group. LDLNs have an important and increasing role to play in advising on and establishing adjustments that are both reasonable and achievable. © 2015 John Wiley & Sons Ltd.

Full Text Available The aim of presented study was to evaluate selected surface spine coil, and low-field magnetic resonance (MR selected sequences in diagnosing hydrocephalus in dogs. This paper discusses 19 dogs (14 canine patients with hydrocephalus and 5 healthy dogs, of five breeds, subjected to low-field magnetic resonance imaging (MRI of hydrocephalus. Area of the lateral ventricles and brain were examined in dogs with hydrocephalus using low-field MRI (at 0.25 Tesla. The MRI of FSE REL, SE, FLAIR, STIR, 3D HYCE, T3DT1, GE STIR 3D and 3D SHARC sequences with an indication of the most effective sequences are described. Additionally, coils for MR were compared, and models for infusion anesthesia were described. As a result of performed study all estimated sequences were diagnostically useful. However, spinal coil No. 2 (ESAOTE was the most optimal for examining and positioning the cranium.

To promote simulation as a learning strategy to support undergraduate nursing students with disabilities. Supporting undergraduate nursing students with disabilities has gained further momentum because of amendments to the Disability Discrimination Act in 2009. Providers of higher education must now ensure proactive steps to prevent discrimination against students with a disability are implemented to assist in course progression. Simulation allows for the impact of a student's disability to be assessed and informs the determination of reasonable adjustments to be implemented. Further suitable adjustments can then be determined in a safe environment and evaluated prior to scheduled placement. Auditing in this manner, offers a risk management strategy for all while maintaining the academic integrity of the program. Discursive. Low, medium and high fidelity simulation activities critically analysed and their application to support undergraduate nursing students with disabilities assessed. With advancing technology and new pedagogical approaches simulation as a learning strategy can play a significant role. In this role, simulation supports undergraduate nursing students with disabilities to meet course requirements, while offering higher education providers an important risk management strategy. The discussion recommends simulation is used to inform the determination of reasonable adjustments for undergraduate nursing students with disabilities as an effective, contemporary curriculum practice. Adoption of simulation, in this way, will meet three imperatives: comply with current legislative requirements, embrace advances in learning technologies and embed one of the six principles of inclusive curriculum. Achieving these imperatives is likely to increase accessibility for all students and offer students with a disability a supportive learning experience. Provides capacity to systematically assess, monitor, evaluate and support students with a disability. The students

The functional outcome of cerebral hemodynamics in the chronic stage of juvenile hydrocephalus was determined using single photon emission computed tomography (SPECT). Five patients including three with aqueductal stenosis, one with post-meningitic hydrocephalus, and one case with hydrocephalus having developed after repair of a huge occipital encephalocele. Early images of cerebral blood flow (CBF) were obtained 25 minutes after intravenous injection of 123-I-iodoamphetamine (IMP), and late images were scanned 3 hours later. Cerebral blood volume (CBV) was also measured using 99m Tc in three patients. Twenty cases with adult communicating hydrocephalus were also investigated from the point of view of shunt effectiveness. Although there was no remarkable change in the cerebrovascular bed in the juvenile cases, CBF of the remnant brain parenchyma was good irrespective of the degree of ventricular dilatation. There was a periventricular-related IMP uptake in each case; however, it somehow matched the ventricular span. Functional outcome one to 23 years after the initial shunt operation was good in every case, despite multiple shunt revisions. Redistribution on late images had no bearing on clinical states. In adult cases, 8 patients with effective shunting demonstrated a relatively localized periventricular low perfusion, with preoperative increased cerebrospinal fluid (CSF) pressure. On the contrary, 12 patients with no improvement with or without ventricular-reduced IMP uptake, despite low CSF pressure. The present study indicates that periventricular hemodynamics may play an important role in cerebral function compromised by hydrocephalus. (J.P.N.)

Full Text Available Learning disability includes wide range of educational problems which treating these problems need child's social, emotional and behavior treatment. As prevalence of learning disabilities among children and their difficulties, the purpose of this study was to investigate the effect of coping with stress training on social adjustment of students with learning disabilities. The statistical population consists of all boy student with learning disabilities in learning disabilities center, in which 34 students were selected by convenience sampling. The social adjustment questionnaire was used. The experimental group had coping strategies training in 9 sessions for 90 minutes every week. Covariance analysis was used to compare the scores. The results showed that there was significant difference in pretest and posttest of experimental group. The findings also indicated that coping strategies training increased social adjustment, affective and educational adjustments of experimental group in comparison of control group. Appropriate strategies can be used for dealing with stress in students with learning disabilities. Coping training can be used as supplemental program in schools and centers of learning disabilities to improve the adjustment problems of these students.

Providing equal-status contact between those with and without disabilities can improve attitudes and reduce discrimination toward individuals with disabilities. This study investigated community service learning as a means by which to provide college students with equal-status contact with individuals with disabilities and increase their positive attitudes toward those with disabilities. A total of 166 college students in one university in the United States enrolled in an Introduction to Disability course received content on disability in society and participated in community service involving 20h of direct contact with individuals with disabilities. Findings indicated that college students who had prior contact with individuals with disabilities had more positive attitudes toward individuals with disabilities than college students who did not have prior contact at the start of the course. For the college students who did not have any prior contact, their attitudes toward individuals with disabilities became significantly more positive at the end of the community service learning course. Implications and suggestions for future research are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Accurate estimation of developmental trajectories can inform instruction and intervention. We compared the fit of linear, quadratic, and piecewise mixed-effects models of reading development among students with learning disabilities relative to their typically developing peers. We drew an analytic sample of 1,990 students from the nationally representative Early Childhood Longitudinal Study-Kindergarten Cohort of 1998, using reading achievement scores from kindergarten through eighth grade to estimate three models of students' reading growth. The piecewise mixed-effects models provided the best functional form of the students' reading trajectories as indicated by model fit indices. Results showed slightly different trajectories between students with learning disabilities and without disabilities, with varying but divergent rates of growth throughout elementary grades, as well as an increasing gap over time. These results highlight the need for additional research on appropriate methods for modeling reading trajectories and the implications for students' response to instruction.

Communicative difficulties affect interactions between people with learning disabilities and their carers. Despite such difficulties, however, some carers seem to interact successfully with people who have limited ability to communicate verbally and exhibit challenging behaviour. This study aims to illuminate skilled interaction among carers working in special accommodations for people with learning disabilities. Interactions between 16 caregivers and 11 residents with learning disabilities were recorded on video. Verbal and non-verbal interaction skills among the carers were identified. Four caring situations with people with learning disabilities were chosen to illuminate skilled interaction. The transcribed text was subjected to qualitative content analysis and core stories were created. The results show that skilled interaction between the carers and the people with learning disabilities is based upon being confirming, sharing daily life experience, giving time and space, and using congruent and distinct language. In this paper we present examples that offer concrete suggestions of how to promote successful interaction and create meaning in the shared day-to-day life in special accommodations for people with learning disabilities. © 2012 John Wiley & Sons Ltd.

A review of 23 studies investigating the prevalence of Behavioural and psychological symptoms of dementia (BPSD) in the general and learning disability population and measures used to assess BPSD was carried out. BPSD are non-cognitive symptoms, which constitute as a major component of dementia regardless of its subtype Research has indicated that there is a high prevalence of BPSD in the general dementia population. There are limited studies, which investigate the prevalence of BPSD within individuals who have learning disabilities and dementia. Findings suggest BPSDs are present within individuals with learning disabilities and dementia. Future research should use updated tools for investigating the prevalence of BPSD within individuals with learning disabilities and dementia.

This paper reports on an investigation into the skills and competencies of forensic learning disability nurses in the United Kingdom. The two sample populations were forensic learning disability nurses from the high, medium, and low secure psychiatric services and non-forensic learning disability nurses from generic services. An information gathering schedule was used to collect the data; of 1200 schedules, 643 were returned for a response rate of 53.5%. The data identified the "top ten" problems that forensic learning disability nurses may encounter, the skills and competencies necessary to overcome them, and the areas that need to be developed in the future. The results indicated that the forensic learning disability nurses tended to focus on the physical aspects to the role whilst the non-forensic learning disability nurses tended to perceive the forensic role in relational terms. This has implications for practice, policy, and procedures.

Children born extremely preterm are at high risk for intellectual disability, learning disabilities, executive dysfunction and special educational needs, but little is understood about the comorbidity of intellectual and learning disabilities in this population. This study explored comorbidity in intellectual disability (ID) and learning disabilities (LD) in children born extremely preterm (EP; disabilities. LD were associated with a 3 times increased risk for SEN. However, EP children with ID alone had poorer neuropsychological abilities and curriculum-based attainment than children with no disabilities, yet there was no increase in SEN provision among this group. EP children are at high risk for comorbid intellectual and learning disabilities. Education professionals should be aware of the complex nature of EP children's difficulties and the need for multi-domain assessments to guide intervention. Copyright © 2016 Elsevier Ireland Ltd.

'It's got so politically correct now': parents' talk about empowering individuals with learning disabilities.

Jingree, Treena; Finlay, W M L

2012-03-01

Over the last decade the UK Government has made proposals to empower individuals with learning disabilities. Strategies have been implemented to reduce institutionalisation and social segregation. Consequently, some learning disability services are being phased out and the focus of care has moved away from institutions and into the community and family domain. Focusing on discourse as a site for social action and identity construction, we used critical discursive psychology to examine focus group discussions between family carers about facilitating the independence of adult family members with learning disabilities. Unlike official UK Government and learning disability services' constructions of empowerment policy, we found that parents invoked empowerment talk: (1) as a resource to construct the facilitation of independence as an abstract, irresponsible, politically correct professional trend; (2) dilemmatically with meritocratic or practical arguments to undermine notions of facilitating choices; and (3) as a resource to construct new service developments as contrary to the preferences of people with learning disabilities. Parents also described individuals with learning disabilities as unable to cope, and drew stark contrasts between their practice and those of service-professionals when expressing concerns about empowerment. We discuss possible implications of such discourses and contrasts on opportunities for empowering individuals with learning disabilities. © 2011 The Authors.

People with learning disabilities are living longer lives. Over the past few years, research has explored the needs of people with learning disabilities, their families and learning disability professionals in relation to end-of-life care and death. However, little is known about the needs of paid carers and their experience of end-of-life care. This article discusses the development, implementation and evaluation of a study day about end-of-life care that was delivered to paid carers on two separate occasions in Berkshire Healthcare NHS Foundation Trust. A total of 43 paid carers attended and the days were well evaluated. The need for further training for paid carers who work with people with learning disabilities at the end of life was highlighted.

Maria Rosa Pizzamiglio

Full Text Available Studies suggest that genetic factors are associated with the etiology of learning disabilities. Incontinentia Pigmenti (IP, OMIM#308300, which is caused by mutations of the IKBKG/NEMO gene, is a rare X-linked genomic disorder (1:10000/20:000 that affects the neuroectodermal tissues. It always affects the skin and sometimes the hair, teeth, nails, eyes and central nervous system (CNS. Data from IP patients demonstrate the heterogeneity of the clinical phenotype; about 30% have CNS manifestations. This extreme variability suggests that IP patients might also have learning disabilities. However, no studies in the literature have evaluated the cognitive profile of IP patients. In fact, the learning disability may go unnoticed in general neurological analyses, which focus on major disabling manifestations of the CNS. Here, we investigated the neuropsychological outcomes of a selected group of IP-patients by focusing on learning disabilities. We enrolled 10 women with IP (7 without mental retardation and 3 with mild to severe mental retardation whose clinical diagnosis had been confirmed by the presence of a recurrent deletion in the IKBKG/NEMO gene. The participants were recruited from the Italian patients' association (I.P.A.SS.I. Onlus. They were submitted to a cognitive assessment that included the Wechsler Adult Intelligence scale and a battery of tests examining reading, arithmetic and writing skills. We found that 7 patients had deficits in calculation/arithmetic reasoning and reading but not writing skills; the remaining 3 had severe to mild intellectual disabilities. Results of this comprehensive evaluation of the molecular and psychoneurological aspects of IP make it possible to place "learning disabilities" among the CNS manifestations of the disease and suggest that the IKBKG/NEMO gene is a genetic determinant of this CNS defect. Our findings indicate the importance of an appropriate psychoneurological evaluation of IP patients, which

From changeling to citizen: learning disability and its representation in museums

Directory of Open Access Journals (Sweden)

Kathy Allday

2009-03-01

Full Text Available This paper examines why museums, both currently and historically, have excluded material relating to people with intellectual impairments. The national picture is examined briefly before the focus shifts to three UK museums in York, Leeds and Colchester where curatorial attitudes to including and presenting material on learning disability are compared and contrasted. Curatorial anxieties about the subject, a lack of national guidance on how to address learning disability in museum collections and displays and the elusive nature of available sources of material appears to discourage museums addressing the issue. Nevertheless, a few examples show that with organizational and professional commitment and the adoption of facilitative and consultative approaches, museums can present the history of learning disability in exciting and thought provoking ways that challenge pre-conceptions about intellectually impaired people. Given museums’ responsibilities under the Disability Discrimination Act (2005, the significance of the social inclusion agenda and calls for new museological practices, there has never been a better time for museums to reevaluate their approaches to learning impairment.

The prevalence of oral diseases including dental caries and periodontal conditions is remarkably higher in people with disabilities. The provision of accessible oral health services for people with learning disabilities may be challenging. The objectives of the review were to identify barriers in accessing oral health care that persists within society, enabling or disabling people with learning disabilities. Using the Arksey O'Malley framework, a scoping review was conducted on PubMed/Medline, OVIDSP, and EMBASE. Studies were evaluated and short-listed based on the inclusion criteria, which consisted of: (1) study participants or population with learning disabilities, (2) aged 16 years or over, (3) reporting on access to oral health services, (4) published in the English language. Those that justified the inclusion criteria were carefully chosen after a blind peer-reviewed process when relevance and quality were debated. Nine studies were eventually included from searches. Tabulation of data was done under the heading of study type, outcomes, the year of publication and patient selection. The majority of studies provided a biomedical overview of access for adults with learning disabilities. The concept of access for people with disability is still ill-defined and obscure. Access to oral health care and needs of people with learning disabilities are complex and multi-facet.

Using assistive technology adaptations to include students with learning disabilities in cooperative learning activities.

Science.gov (United States)

Bryant, D P; Bryant, B R

1998-01-01

Cooperative learning (CL) is a common instructional arrangement that is used by classroom teachers to foster academic achievement and social acceptance of students with and without learning disabilities. Cooperative learning is appealing to classroom teachers because it can provide an opportunity for more instruction and feedback by peers than can be provided by teachers to individual students who require extra assistance. Recent studies suggest that students with LD may need adaptations during cooperative learning activities. The use of assistive technology adaptations may be necessary to help some students with LD compensate for their specific learning difficulties so that they can engage more readily in cooperative learning activities. A process for integrating technology adaptations into cooperative learning activities is discussed in terms of three components: selecting adaptations, monitoring the use of the adaptations during cooperative learning activities, and evaluating the adaptations' effectiveness. The article concludes with comments regarding barriers to and support systems for technology integration, technology and effective instructional practices, and the need to consider technology adaptations for students who have learning disabilities.

Learning Disabilities and Emotional Intelligence.

2017-07-04

The literature is conflicted around the subject of the emotional abilities of individuals with Specific Learning Disabilities (SLDs): While many claim cognitive challenges are associated with emotional difficulties, some suggest emotional and interpersonal abilities are not compromised in such disorders and may help individuals compensate and cope effectively with the challenges they meet in learning environments. Two studies explored differences in emotional intelligence (EI) between young adults with and without SLD. Two samples (matched on gender, approximate age, and program of study; n = 100, and unmatched; n = 584) of college students took self-report and performance-based tests of EI (Ability-EI) as well as a measure of self-esteem and demographics associated with college performance (e.g.: SAT scores, gender, etc.). The results showed that while SAT scores and ability emotional intelligence (Ability-EI) were associated with college GPA, Ability-EI did not differ between the two groups, while self-report measures of EI and self-esteem did show differences, with the group with learning disabilities ranking lower. The effects remained stable when we controlled for demographics and potential intervening factors. The results suggest that EI may play a protective role in the association between background variables and college attainment in students with SLD. The results may provide a basis for interventions to empower students with SLD in academia.

Hoerig, Dianne C; David, Andrew S; D'Amato, Rik Carl

2002-12-01

Although both intelligence tests and memory tests are commonly used in neuropsychological examinations, the relationship between memory and intelligence has not been fully explored, particularly for children having learning disabilities. Memory, or the ability to retain information, was evaluated using the Test of Memory and Learning, a recently released test that gives a comprehensive measure of global memory functioning. This, and the Wechsler Intelligence Scale for Children-Third Edition, used to assess intelligence, were given to 80 students with learning disabilities. The correlation between a global measure of memory and a global measure f intelligence was significant (r = .59), indicating that memory should be viewed as an important component when evaluating children with learning disabilities.

Hydrocephalus can develop secondarily to a disturbance in production, flow and/or absorption of cerebrospinal fluid. Experimental models of hydrocephalus, especially subacute and chronic hydrocephalus, are few and limited, and the effects of hydrocephalus on the subventricular zone are unclear. The aim of this study was to analyze the effects of long-term obstructive hydrocephalus on the subventricular zone, which is the neurogenic niche lining the lateral ventricles. We developed a new method to induce hydrocephalus by obstructing the aqueduct of Sylvius in the mouse brain, thus simulating aqueductal stenosis in humans. In 120-day-old rodents (n = 18 per group), the degree of ventricular dilatation and cellular composition of the subventricular zone were studied by immunofluorescence and transmission electron microscopy. In adult patients (age > 18 years), the sizes of the subventricular zone, corpus callosum, and internal capsule were analyzed by magnetic resonance images obtained from patients with and without aqueductal stenosis (n=25 per group). Mice with 60-day hydrocephalus had a reduced number of Ki67+ and doublecortin+ cells on immunofluorescence, as well as decreased number of neural progenitors and neuroblasts in the subventricular zone on electron microscopy analysis as compared to non-hydrocephalic mice. Remarkably, a number of extracellular matrix structures (fractones) contacting the ventricular lumen and blood vessels were also observed around the subventricular zone in mice with hydrocephalus. In humans, the widths of the subventricular zone, corpus callosum, and internal capsule in patients with aqueductal stenosis were significantly smaller than age and gender-matched patients without aqueductal stenosis. In summary, supratentorial hydrocephalus reduces the proliferation rate of neural progenitors and modifies the cytoarchitecture and extracellular matrix compounds of the subventricular zone. In humans, this similar process reduces the

Reimagining Disability and Inclusive Education Through Universal Design for Learning

Directory of Open Access Journals (Sweden)

Jan Doolittle Wilson

2017-06-01

Full Text Available In 1975, Congress enacted a law eventually known as the Individuals with Disabilities Education Act (IDEA, which ensures that children with disabilities receive a free, appropriate, public education. Since then, scholarly and popular debates about the effectiveness of inclusive education have proliferated and typically focus on the ability or inability of students with disabilities to succeed in so-called regular classrooms. These debates reflect widespread assumptions that the regular classroom is rightly the province of nondisabled students and a neutral, value-free space that students with disabilities invade and disrupt via their very presence and their costly needs for adaptation. But as many scholars in the field of Disability Studies in Education (DSE have argued, these discussions often fail to recognize that the space of the regular classroom, far from neutral, is constructed for a nondisabled, neurotypical, white, male, middle-class "norm" that neither reflects nor accommodates the wide range of diverse learners within it, regardless of whether these learners have been diagnosed with a disability. A DSE perspective sees the educational environment, not students with disabilities, as the "problem" and calls for a Universal Design for Learning approach to education, or the design of instructional materials and activities that allows the learning goals to be achievable by individuals with wide differences in their abilities and backgrounds. Agreeing with this DSE perspective, this article uses an autoethnographic approach to reexamine inclusive education and to consider how university classrooms, pedagogy, and curricular materials can be improved in order to accommodate all students, not just those with disabilities. Ultimately, the article argues that Universal Design for Learning has the potential to radically transform the meaning of inclusive education and the very concept of disability.

Predictors and outcomes of shunt-dependent hydrocephalus in patients with aneurysmal sub-arachnoid hemorrhage

Science.gov (United States)

2012-01-01

Background Hydrocephalus following spontaneous aneurysmal sub-arachnoid hemorrhage (SAH) is often associated with unfavorable outcome. This study aimed to determine the potential risk factors and outcomes of shunt-dependent hydrocephalus in aneurysmal SAH patients but without hydrocephalus upon arrival at the hospital. Methods One hundred and sixty-eight aneurysmal SAH patients were evaluated. Using functional scores, those without hydrocephalus upon arrival at the hospital were compared to those already with hydrocephalus on admission, those who developed it during hospitalization, and those who did not develop it throughout their hospital stay. The Glasgow Coma Score, modified Fisher SAH grade, and World Federation of Neurosurgical Societies grade were determined at the emergency room. Therapeutic outcomes immediately after discharge and 18 months after were assessed using the Glasgow Outcome Score. Results Hydrocephalus accounted for 61.9% (104/168) of all episodes, including 82 with initial hydrocephalus on admission and 22 with subsequent hydrocephalus. Both the presence of intra-ventricular hemorrhage on admission and post-operative intra-cerebral hemorrhage were independently associated with shunt-dependent hydrocephalus in patients without hydrocephalus on admission. After a minimum 1.5 years of follow-up, the mean Glasgow outcome score was 3.33 ± 1.40 for patients with shunt-dependent hydrocephalus and 4.21 ± 1.19 for those without. Conclusions The presence of intra-ventricular hemorrhage, lower mean Glasgow Coma Scale score, and higher mean scores of the modified Fisher SAH and World Federation of Neurosurgical grading on admission imply risk of shunt-dependent hydrocephalus in patients without initial hydrocephalus. These patients have worse short- and long-term outcomes and longer hospitalization. PMID:22765765

There is a known association of hydrocephalus with encephaloceles. Risk factors for hydrocephalus and neurological deficit were ascertained in a series of patients born with an encephalocele. A retrospective analysis was undertaken of patients treated for encephaloceles at Children's Hospital Los Angeles between 1994 and 2012. The following factors were evaluated for their prognostic value: age at presentation, sex, location of encephalocele, size, contents, microcephaly, presence of hydrocephalus, CSF leak, associated cranial anomalies, and neurological outcome. Seventy children were identified, including 38 girls and 32 boys. The median age at presentation was 2 months. The mean follow-up duration was 3.7 years. Encephalocele location was classified as anterior (n = 14) or posterior (n = 56) to the coronal suture. The average maximum encephalocele diameter was 4 cm (range 0.5-23 cm). Forty-seven encephaloceles contained neural tissue. Eight infants presented at birth with CSF leaking from the encephalocele, with 1 being infected. Six patients presented with hydrocephalus, while 11 developed progressive hydrocephalus postoperatively. On univariate analysis, the presence of neural tissue, cranial anomalies, encephalocele size of at least 2 cm, seizure disorder, and microcephaly were each positively associated with hydrocephalus. On multivariate logistic regression modeling, the single prognostic factor for hydrocephalus of borderline statistical significance was the presence of neural tissue (odds ratio [OR] = 5.8, 95% confidence interval [CI] = 0.8-74.0). Fourteen patients had severe developmental delay, 28 had mild/moderate delay, and 28 were neurologically normal. On univariate analysis, the presence of cranial anomalies, larger size of encephalocele, hydrocephalus, and microcephaly were positively associated with neurological deficit. In the multivariable model, the only statistically significant prognostic factor for neurological deficit was presence of

In prior work, children born to mothers who received neuraxial anesthesia for cesarean delivery had a lower incidence of subsequent learning disabilities compared with vaginal delivery. The authors speculated that neuraxial anesthesia may reduce stress responses to delivery, which could affect subsequent neurodevelopmental outcomes. To further explore this possibility, we examined the association between the use of neuraxial labor analgesia and development of childhood learning disabilities in a population-based birth cohort of children delivered vaginally. The educational and medical records of all children born to mothers residing in the area of 5 townships of Olmsted County, Minnesota from 1976 to 1982 and remaining in the community at age 5 years were reviewed to identify those with learning disabilities. Cox proportional hazards regression was used to compare the incidence of learning disabilities between children delivered vaginally with and without neuraxial labor analgesia, including analyses adjusted for factors of either potential clinical relevance or that differed between the 2 groups in univariate analysis. Of the study cohort, 4684 mothers delivered children vaginally, with 1495 receiving neuraxial labor analgesia. The presence of childhood learning disabilities in the cohort was not associated with use of labor neuraxial analgesia (adjusted hazard ratio, 1.05; 95%confidence interval, 0.85-1.31; P = 0.63). The use of neuraxial analgesia during labor and vaginal delivery was not independently associated with learning disabilities diagnosed before age 19 years. Future studies are needed to evaluate potential mechanisms of the previous finding indicating that the incidence of learning disabilities is lower in children born to mothers via cesarean delivery under neuraxial anesthesia compared with vaginal delivery.

Full Text Available Background and Aim: Learning disability is a term referes to a group of disorders manifesting listening, reading, writing, or mathematical problems. These children mostly have attention difficulties in classroom that leads to many learning problems. In this study we aimed to compare the auditory attention of 7 to 9 year old children with learning disability to non- learning disability age matched normal group.Methods: Twenty seven male 7 to 9 year old students with learning disability and 27 age and sex matched normal conrols were selected with unprobable simple sampling. 27 In order to evaluate auditory selective and divided attention, Farsi versions of speech in noise and dichotic digit test were used respectively.Results: Comparison of mean scores of Farsi versions of speech in noise in both ears of 7 and 8 year-old students in two groups indicated no significant difference (p>0.05 Mean scores of 9 year old controls was significant more than those of the cases only in the right ear (p=0.033. However, no significant difference was observed between mean scores of dichotic digit test assessing the right ear of 9 year-old learning disability and non learning disability students (p>0.05. Moreover, mean scores of 7 and 8 year- old students with learning disability was less than those of their normal peers in the left ear (p>0.05.Conclusion: Selective auditory attention is not affected in the optimal signal to noise ratio, while divided attention seems to be affected by maturity delay of auditory system or central auditory system disorders.

Yu, Bo; Li, Shasha; Lin, Zhenlang; Zhang, Nu

2009-01-01

To investigate the effectiveness of subcutaneous reservoir drainage as a treatment for the different types of posthemorrhagic hydrocephalus in premature infants. 11 premature infants with posthemorrhagic hydrocephalus underwent subcutaneous reservoir embedment surgery, and cerebrospinal fluid (CSF) was drained via the reservoir intermittently for 8 weeks. During the period of drainage, ultrasound and computerized tomography were used to measure ventricle size. CSF examinations were performed routinely to assess the presence of intraventricular hemorrhage (IVH) and/or infection. (1) Five infants were diagnosed as having obstructive hydrocephalus; 2 had nearly normal ventricle sizes with treatment and drainage was stopped after 8 weeks, 2 had nearly normal ventricle sizes after 4 more weeks of drainage, and 1 underwent ventriculoperitoneal shunt (V-P shunt) surgery due to failure of ventricle size reduction. (2) Six infants were diagnosed as having communicating hydrocephalus; 4 had further enlarged ventricle size after 8 weeks and underwent V-P shunt surgery, 1 had treatment aborted at week 8 of drainage, and only 1 had moderate reduction of ventricle size after 8 weeks. (3) None of the 11 infants had progressive IVH and/or intracranial infection during drainage. Subcutaneous reservoir drainage is a suitable and safe treatment for posthemorrhagic hydrocephalus in premature infants. It is more effective for obstructive hydrocephalus than for communicating hydrocephalus. Copyright (c) 2009 S. Karger AG, Basel.

Gamma knife radiosurgery (GKRS) has been established as an effective and safe treatment for intracranial schwannoma. However, serious complications can occur after GKRS, including hydrocephalus. The pathophysiology and risk factors of this disorder are not yet fully understood. The objective of the study was to assess potential risk factors for hydrocephalus after GKRS. We retrospectively reviewed the medical radiosurgical records of 244 patients who underwent GKRS to treat intracranial schwannoma. The following parameters were analyzed as potential risk factors for hydrocephalus after GKRS: age, sex, target volume, irradiation dose, prior tumor resection, treatment technique, and tumor enhancement pattern. The tumor enhancement pattern was divided into 2 groups: group A (homogeneous enhancement) and group B (heterogeneous or rim enhancement). Of the 244 patients, 14 of them (5.7%) developed communicating hydrocephalus. Communicating hydrocephalus occurred within 2 years after GKRS in most patients (92.8%). No significant association was observed between any of the parameters investigated and the development of hydrocephalus, with the exception of tumor enhancement pattern. Group B exhibited a statistically significant difference by univariate analysis (P = 0.002); this difference was also significant by multivariate analysis (P = 0.006). Because hydrocephalus is curable, patients should be closely monitored for the development of this disorder after GKRS. In particular, patients with intracranial schwannomas with irregular enhancement patterns or cysts should be meticulously observed. Copyright © 2015 Elsevier Inc. All rights reserved.

Simulation of hydrocephalus condition in infant head

Science.gov (United States)

Wijayanti, Erna; Arif, Idam

2014-03-01

Hydrocephalus is a condition of an excessive of cerebrospinal fluid in brain. In this paper, we try to simulate the behavior of hydrocephalus conditions in infant head by using a hydro-elastic model which is combined with orthotropic elastic skull and with the addition of suture that divide the skull into two lobes. The model then gives predictions for the case of stenosis aqueduct by varying the cerebral aqueduct diameter, time constant and brain elastic modulus. The hydrocephalus condition which is shown by the significant value of ventricle displacement, as the result shows, is occurred when the aqueduct is as resistant as brain parenchyma for the flow of cerebrospinal fluid. The decrement of brain elastic modulus causes brain parenchyma displacement value approach ventricle displacement value. The smaller of time constant value causes the smaller value of ventricle displacement.

Few systematic assessments of developmental forms of hydrocephalus exist. We reviewed magnetic resonance images (MRIs) and clinical records of patients with infancy-onset hydrocephalus. Among 411 infants, 236 had hydrocephalus with no recognizable extrinsic cause. These children were assigned to 1 of 5 subtypes and compared on the basis of clinical characteristics and developmental and surgical outcomes. At an average age of 5.3 years, 72% of children were walking independently and 87% could eat by mouth; in addition, 18% had epilepsy. Distinct patterns of associated malformations and syndromes were observed within each subtype. On average, children with aqueductal obstruction, cysts, and encephaloceles had worse clinical outcomes than those with other forms of developmental hydrocephalus. Overall, 53% of surgically treated patients experienced at least 1 shunt failure, but hydrocephalus associated with posterior fossa crowding required fewer shunt revisions. We conclude that each subtype of developmental hydrocephalus is associated with distinct clinical characteristics, syndromology, and outcomes, suggesting differences in underlying mechanisms. © The Author(s) 2015.

Preventricular lucency in computerized tomography of various forms of hydrocephalus

Sprung, C.

602 patients with 8 different types of hydrocephalus have been examined for PVL on the basis of 18,413 CT pictures. The localisation of PVL, in the periventricular white matter of the auterior horns, and its configuration are independent of the type of hydrocephalus and of the intraventricular pressure. In contrast, the intensity and incidence of PVL are a function of the type of hydrocephalus. Factors influencing these two parameters are in order of importance: The intraventricular pressure, the acuteness of the process leading to stenosis (i.e. the rate of development of hydrocephalus), the extent of ventricular enlargement, the compliance of ventricular wall and osseous part of the skull, the volume of the ventricles, and the localisation of the obstructing and displacing process. Independent of the type of hydrocephalus, disappearance of PVL is always well correlated with improved clinical symptoms and, in most cases, also with a reduction of the ventricular volume. As far as the pathomechanism is concerned, the studies suggest passive inflow of liquor through the damaged ependyma rather than an active absorption process. (orig./MG) [de

Background Identifying patients with learning disabilities within primary care is central to initiatives for improving the health of this population. UK general practitioners (GPs) receive additional income for maintaining registers of patients with learning disabilities as part of the Quality and Outcomes Framework (QOF), and may opt to provide Directed Enhanced Services (DES), which requires practices to maintain registers of patients with moderate or severe learning disabilities and offer them annual health checks. Objectives This paper describes the development of a register of patients with moderate or severe learning disabilities at one UK general practice. Methods A Read code search of one UK general practice's electronic medical records was conducted in order to identify patients with learning disabilities. Confirmation of diagnoses was sought by scrutinising records and GP verification. Cross-referencing with the practice QOF register of patients with learning disabilities of any severity, and the local authority's list of clients with learning disabilities, was performed. Results Of 15 001 patients, 229 (1.5%) were identified by the Read code search as possibly having learning disabilities. Scrutiny of records and GP verification confirmed 64 had learning disabilities and 24 did not, but the presence or absence of learning disability remained unclear in 141 cases. Cross-referencing with the QOF register (n=81) and local authority list (n=49) revealed little overlap. Conclusion Identifying learning disability and assessing its severity are tasks GPs may be unfamiliar with, and relying on Read code searches may result in under-detection. Further research is needed to define optimum strategies for identifying, cross-referencing and validating practice-based registers of patients with learning disabilities. PMID:22479290

Multiple intelligences and underachievement: lessons from individuals with learning disabilities.

Science.gov (United States)

Hearne, D; Stone, S

1995-01-01

The field of learning disabilities, like education in the main, is undergoing calls for reform and restructuring, an upheaval brought on in great part by the forces of opposing paradigms--reductionism and constructivism. In reexamining our past, we must begin to address the failures of traditional deficit models and their abysmally low "cure" rate. Several new theories have arisen that challenge traditional practices in both general and special education classrooms. Particularly influential has been the work of Howard Gardner, whose theory of multiple intelligences calls for a restructuring of our schools to accommodate modes of learning and inquiry with something other than deficit approaches. At least some current research in the field of learning disabilities has begun to focus on creativity and nontraditional strengths and talents that have not been well understood or highly valued by the schools. In this article, we briefly summarize the findings in our search for the talents of students labeled learning disabled, evidence of their abilities, implications of these for the schools, and a beginning set of practical recommendations.

Teacher response to learning disability: a test of attributional principles.

Science.gov (United States)

Clark, M D

1997-01-01

Attribution research has identified student ability and effort expended as causes of achievement outcomes that result in differing teacher affect, evaluative feedback, and expectation of future performance. Ninety-seven elementary-school general education teachers (84 women and 13 men) rated their responses to the test failures of hypothetical boys with and without learning disabilities. In most cases, greater reward and less punishment, less anger and more pity, and higher expectations of future failure followed the negative outcomes of the boys with learning disabilities, when compared with their nondisabled ability and effort matches, indicating that learning disability acts as a cause of achievement outcomes in the same way as ability and effort. This pattern of teacher affect and response can send negative messages that are often interpreted as low-ability cues, thus affecting students' self-esteem, sense of competence as learners, and motivation to achieve.

2016-04-01

Full Text Available Idiopathic normal pressure hydrocephalus (iNPH is a potentially reversible neurodegenerative disease commonly characterized by a triad of dementia, gait, and urinary disturbance. Advancements in diagnosis and treatment have aided in properly identifying and improving symptoms in patients. However, a large proportion of iNPH patients remain either undiagnosed or misdiagnosed. Using PubMed search engine of keywords “normal pressure hydrocephalus,” “diagnosis,” “shunt treatment,” “biomarkers,” “gait disturbances,” “cognitive function,” “neuropsychology,” “imaging,” and “pathogenesis,” articles were obtained for this review. The majority of the articles were retrieved from the past 10 years. The purpose of this review article is to aid general practitioners in further understanding current findings on the pathogenesis, diagnosis, and treatment of iNPH.

Suzuki, Hiroshi; Ogawa, Kimio; Hibio, Shuichi; Goto, Kazuhiko; Shiihara, Hiroaki

1984-01-01

Based on CT findings one year after shunting, ventricular dialtion was classified into five degrees for examining prognosis of communicating hydrocephalus subsequent to purulent meningitis. Factors causing and aggravating hydrocephalus were also examined. Patients with hydrocephalus tended to have spasms frequently as the first symptom within one month after birth when there were few characteristic findings. Spasm and disturbance of consciousness occurred frequently during the first week of the occurrence of disease. Large numbers of cells in the spinal fluid and high volume of spinal cord protein were persistent in patients aged one month or less. Chloride transport decreased in patients aged two months or more. The occurrence of syndrome of the pyramidal tract, eye symptoms, movement of head to the left and right, and involuntary movement suggested serious conditions of the disease. Disturbance of movement could be relieved by giving adequate antibiotics as soon as meningitis was discovered within one month after birth and by giving chloramphenicol when symptoms suggesting the development of serious conditions occurred. However, mental retardation and epilepsy could not be prevented. (Namekawa, K.)

Ginsburg, Faye; Rapp, Rayna

2013-12-01

Our article draws on one aspect of our multi-sited long-term ethnographic research in New York City on cultural innovation and Learning Disabilities (LD). We focus on our efforts to help create two innovative transition programs that also became sites for our study when we discovered that young adults with disabilities were too often "transitioning to nowhere" as they left high school. Because of our stakes in this process as parents of children with learning disabilities as well as anthropologists, we have come to think of our method as entangled ethnography, bringing the insights of both insider and outsider perspectives into productive dialog, tailoring a longstanding approach in critical anthropology to research demedicalizing the experience of disability.

Geary, David C

2005-01-01

Gersten, Jordan, and Flojo (in this issue) provide the beginnings of an essential bridge between basic research on mathematical disabilities (MD) in young children and the application of this research for the early identification and remediation of these forms of learning disability. As they acknowledge, the field of MD is in the early stages of development, and thus recommendations regarding identification measures and remedial techniques must be considered preliminary. I discuss the importance of maintaining a tight link between theoretical and empirical research on children's developing numerical, arithmetical, and mathematical competencies and future research on learning disabilities in mathematics. This link will provide the foundation for transforming experimental procedures into assessment measures, understanding the cognitive strengths and weaknesses of children with these forms of learning disability, and developing remedial approaches based on the pattern of cognitive strengths and weaknesses for individual children.

Clinical and Surgical Factors Associated With Increased Epilepsy Risk in Children With Hydrocephalus.

Tully, Hannah M; Kukull, Walter A; Mueller, Beth A

2016-06-01

Children with hydrocephalus are at risk for epilepsy both due to their underlying condition and as a consequence of surgical treatment; however, the relative contributions of these factors remain unknown. The authors sought to characterize epilepsy among children with infancy-onset hydrocephalus and to examine the risks of epilepsy associated with hydrocephalus subtype and with factors related to surgical treatment. We conducted a longitudinal cohort study of all children with infancy-onset hydrocephalus treated at a major regional children's hospital during 2002 to 2012, with follow-up to ascertain risk factors and epilepsy outcome through April 2015. Poisson regression was used to calculate adjusted risk ratios and 95% confidence intervals for associations. Among 379 children with hydrocephalus, 86 (23%) developed epilepsy (mean onset age = 2.7 years), almost one fifth of whom had a history of infantile spasms. Relative to spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes had fourfold higher risks of developing epilepsy. Among children who underwent surgery, surgical infection doubled the risk of epilepsy (risk ratio = 2.0, 95% confidence interval = 1.4 to 3.0). Epilepsy was associated with surgical failure for intracranial reasons but not extracranial reasons (risk ratio = 1.7, 95% confidence interval = 1.1 to 2.7; risk ratio = 1.1, 95% confidence interval = 0.7 to 1.9, respectively). Epilepsy is common among children with hydrocephalus. Compared with children with spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes have a markedly increased risk of epilepsy. Surgical infection doubles the risk of epilepsy. Copyright © 2016 Elsevier Inc. All rights reserved.

Children with learning disabilities might have difficulties to communicate effectively and give reliable responses as required in various visual function testing procedures. The purpose of this study was to compare the testability of visual acuity using the modified Early Treatment Diabetic Retinopathy Study (ETDRS) and Cambridge Crowding Cards, stereo acuity using Lang Stereo test II and Butterfly stereo tests and colour perception using Colour Vision Test Made Easy (CVTME) and Ishihara's Test for Colour Deficiency (Ishihara Test) between children in mainstream classes and children with learning disabilities in special education classes in government primary schools. A total of 100 primary school children (50 children from mainstream classes and 50 children from special education classes) matched in age were recruited in this cross-sectional comparative study. The testability was determined by the percentage of children who were able to give reliable respond as required by the respective tests. 'Unable to test' was defined as inappropriate response or uncooperative despite best efforts of the screener. The testability of the modified ETDRS, Butterfly stereo test and Ishihara test for respective visual function tests were found lower among children in special education classes ( P learning disabilities. Modifications of vision testing procedures are essential for children with learning disabilities.

Neuropsychology of Learning Disabilities: The Past and the Future.

Science.gov (United States)

Fletcher, Jack M; Grigorenko, Elena L

2017-10-01

Over the past 50 years, research on children and adults with learning disabilities has seen significant advances. Neuropsychological research historically focused on the administration of tests sensitive to brain dysfunction to identify putative neural mechanisms underlying learning disabilities that would serve as the basis for treatment. Led by research on classifying and identifying learning disabilities, four pivotal changes in research paradigms have produced a contemporary scientific, interdisciplinary, and international understanding of these disabilities. These changes are (1) the emergence of cognitive science, (2) the development of quantitative and molecular genetics, (3) the advent of noninvasive structural and functional neuroimaging, and (4) experimental trials of interventions focused on improving academic skills and addressing comorbid conditions. Implications for practice indicate a need to move neuropsychological assessment away from a primary focus on systematic, comprehensive assessment of cognitive skills toward more targeted performance-based assessments of academic achievement, comorbid conditions, and intervention response that lead directly to evidence-based treatment plans. Future research will continue to cross disciplinary boundaries to address questions regarding the interaction of neurobiological and contextual variables, the importance of individual differences in treatment response, and an expanded research base on (a) the most severe cases, (b) older people with LDs, and (c) domains of math problem solving, reading comprehension, and written expression.

2013-01-01

The Internet and social media are powerful disseminators of medical information, providing new portals for patient care. The authors of this study evaluated current technology hardware, Internet, and social media use and their socioeconomic relationships among caregivers of children with hydrocephalus. A written survey was completed in the neurosurgical clinics at the University of Alabama at Birmingham by 300 parents of children with shunted hydrocephalus between October 26, 2010, and July 26, 2011. Computer use (94.6%), Internet use (91.7%), smartphone use (56.9%), and Internet research on hydrocephalus (81.9%) were prevalent. However, for each of these four utilizations there was significantly lower access by caregivers of minority races (p = 0.04, 0.03, 0.002, and children with similar conditions. Technology hardware, the Internet, and social media are widely used with some skepticism by parents of children with shunted hydrocephalus. Caregivers are interested in physician-recommended Internet resources. Socioeconomic factors including race, income, and level of education reveal a disparity in access to some of these resources, although all groups have relatively high use. Unlike typical technology use, social media use is breaking down the digital divide among ethnic and socioeconomic groups.

The influence of decompressive craniectomy on the development of hydrocephalus: a review

Directory of Open Access Journals (Sweden)

Jun Ding

2014-09-01

Full Text Available Decompressive craniectomy (DC is widely used to treat intracranial hypertension following traumatic brain injury (TBI or cerebral vascular disease. Many studies have discussed complications of this procedure, and hydrocephalus is a common complication of DC. To further evaluate the relationship between DC and hydrocephalus, a review of the literature was performed. Numerous complications may arise after DC, including contusion or hematoma expansion, epilepsy, herniation of the cortex through a bone defect, CSF leakage through the scalp incision, infection, subdural effusion, hydrocephalus and “syndrome of the trephined”. Several hydrocephalus predictors were identified; these included DC, distance from the midline, hygroma, age, injury severity, subarachnoid or intraventricular hemorrhage, delayed time to craniotomy, repeated operation, and duraplasity. However, results differed among studies. The impact of DC on hydrocephalus remains controversial.

Spatial short-term memory in children with nonverbal learning disabilities: impairment in encoding spatial configuration.

Narimoto, Tadamasa; Matsuura, Naomi; Takezawa, Tomohiro; Mitsuhashi, Yoshinori; Hiratani, Michio

2013-01-01

The authors investigated whether impaired spatial short-term memory exhibited by children with nonverbal learning disabilities is due to a problem in the encoding process. Children with or without nonverbal learning disabilities performed a simple spatial test that required them to remember 3, 5, or 7 spatial items presented simultaneously in random positions (i.e., spatial configuration) and to decide if a target item was changed or all items including the target were in the same position. The results showed that, even when the spatial positions in the encoding and probe phases were similar, the mean proportion correct of children with nonverbal learning disabilities was 0.58 while that of children without nonverbal learning disabilities was 0.84. The authors argue with the results that children with nonverbal learning disabilities have difficulty encoding relational information between spatial items, and that this difficulty is responsible for their impaired spatial short-term memory.

A review of the current treatment methods for posthaemorrhagic hydrocephalus of infants

Directory of Open Access Journals (Sweden)

Sparrow Owen

2009-01-01

Full Text Available Abstract Posthaemorrhagic hydrocephalus (PHH is a major problem for premature infants, generally requiring lifelong care. It results from small blood clots inducing scarring within CSF channels impeding CSF circulation. Transforming growth factor – beta is released into CSF and cytokines stimulate deposition of extracellular matrix proteins which potentially obstruct CSF pathways. Prolonged raised pressures and free radical damage incur poor neurodevelopmental outcomes. The most common treatment involves permanent ventricular shunting with all its risks and consequences. This is a review of the current evidence for the treatment and prevention of PHH and shunt dependency. The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library and PubMed (from 1966 to August 2008 were searched. Trials using random or quasi-random patient allocation for any intervention were considered in infants less than 12 months old with PHH. Thirteen trials were identified although speculative interventions were also evaluated. The literature confirms that lumbar punctures, diuretic drugs and intraventricular fibrinolytic therapy can have significant adverse effects and fail to prevent shunt dependence, death or disability. There is no evidence that postnatal phenobarbital administration prevents intraventricular haemorrhage (IVH. Subcutaneous reservoirs and external drains have not been tested in randomized controlled trials, but can be useful as a temporising measure. Drainage, irrigation and fibrinolytic therapy as a way of removing blood to inhibit progressive deposition of matrix proteins, permanent hydrocephalus and shunt dependency, are invasive and experimental. Studies of ventriculo-subgaleal shunts show potential as a temporary method of CSF diversion, but have high infection rates. At present no clinical intervention has been shown to reduce shunt surgery in these infants. A ventricular shunt is not advisable in the early phase after

A palliative care resource for professional carers of people with learning disabilities.

Science.gov (United States)

Reddall, C

2010-07-01

People with learning disabilities who have a life-threatening illness, are as entitled as other members of the population to receive good palliative care in their home of choice. However, professional carers of people with learning disability are generally unaware of the meaning of palliative care, and how they can access palliative care support. More importantly, they may feel they are not capable of caring for a resident with a life-threatening illness in the home environment. This article uses a case study to help illustrate the value of compiling a resource booklet for professional carers of people with learning disabilities. By providing information on palliative care, that is easy to understand and easily accessible, professional carers of these people can have a valuable resource which will enable them to provide general palliative care when needed. (I use the term professional carers to refer to carers who are paid to look after people with learning disabilities either in care homes, or in supported living homes in the general community).

This study determines and compares the attitudes of dentists to the provision of care for people with learning disabilities according to gender, qualification, previous experience of treating patients with learning disabilities and work experience of dentists. A cross-sectional study was conducted among 247 dentists (166 men and 81 women) using a pretested structured questionnaire. This questionnaire assessed the respondent's attitude towards learning-disabled patients in five categories: beliefs about treating them, their capabilities, discrimination against these patients, their social behaviour and quality of care to be received by these patients. The information on dentist's gender, qualification, work experience and previous experience of treating patients with learning disabilities was also collected through questionnaire. The Student's t-test and anova test were used for statistical analysis. The mean attitude score was found to be 71.13 ± 8.97. A statistically significant difference was found in the mean attitude scores of dentists with work experience (p = 0.000). Study subjects with postgraduate qualification and previous experience of treating patients with learning disabilities had significantly greater mean attitude score than their counterparts (p = 0.000). The overall attitude of dentists towards provision of care for people with learning disabilities was favourable, which increased with higher qualification and past experience. © 2012 The Authors.

We present the MR imaging findings in a patient who developed tetraventricular hydrocephalus after massive rupture of dermoid cysts with generalized subarachnoid and ventricular spread of cyst contents. The development of tetraventricular hydrocephalus due to ruptured dermoid is a very unusual complication, and was attributed to cyst contents interfering with passage of cerebrospinal fluid through the arachnoid granulations and fourth ventricular outlet foramina.

People with learning disabilities have been included in research as co-researchers since the 1990s. However, there is limited literature about the processes of involving people with learning disabilities in the more intellectual and analytical stages of the research process. To examine the potential contribution of people with learning disabilities to data analysis in qualitative research. This article is a reflection on one research experience. The two authors include one researcher with and one without learning disabilities. They each describe their experience and understanding of user involvement in analysing the data of an ethnographic study of people with learning disabilities who had cancer. The researcher with learning disabilities was given extensive vignettes and extracts from the research field notes, and was supported to extract themes, which were cross-compared with the analysis of other members of the research team. The researcher with learning disabilities coped well with the emotive content of the data and with the additional support provided, he was able to extract themes that added validity to the overall analysis. His contribution complemented those of the other members of the research team. There were unexpected benefits, in particular, in terms of a more reciprocal and supportive relationship between the two researchers. It is possible and valuable to extend involvement to data analysis, but to avoid tokenism and maintain academic rigour, there must be a clear rationale for such involvement. Extra support, time and costs must be planned for.

The relationship between gross motor skills and academic achievement in children with learning disabilities.

Science.gov (United States)

Westendorp, Marieke; Hartman, Esther; Houwen, Suzanne; Smith, Joanne; Visscher, Chris

2011-01-01

The present study compared the gross motor skills of 7- to 12-year-old children with learning disabilities (n = 104) with those of age-matched typically developing children (n = 104) using the Test of Gross Motor Development-2. Additionally, the specific relationships between subsets of gross motor skills and academic performance in reading, spelling, and mathematics were examined in children with learning disabilities. As expected, the children with learning disabilities scored poorer on both the locomotor and object-control subtests than their typically developing peers. Furthermore, in children with learning disabilities a specific relationship was observed between reading and locomotor skills and a trend was found for a relationship between mathematics and object-control skills: the larger children's learning lag, the poorer their motor skill scores. This study stresses the importance of specific interventions facilitating both motor and academic abilities. Copyright © 2011 Elsevier Ltd. All rights reserved.

Neuroradiological findings in multiloculated hydrocephalus

Energy Technology Data Exchange (ETDEWEB)

Albanese, V.; Tomasello, F.; Sampaolo, S.; Picozzi, P. (Naples Univ. (Italy). Inst. of Neurosurgery)

1982-01-01

The characteristic neuroradiological features of multiloculated hydrocephalus following neonatal meningitis and ventriculitis in five infants are presented. The role of ventriculography and computerized tomography in detecting multiloculated and enlarged ventricles and paraventricular cavities, as well as complete and incomplete septa, is emphasized for early diagnosis and surgical management. CT scan also provides clues indicating the presence of thin but not visualized septa. It is suggested that post-meningitic hydrocephalus should be repeatedly followed-up for detection of multiloculated transformation. Probably this entity occurs less uncommonly than was thought in the past. The CT scan appears the most helpful and safe procedure for the serial evaluation, but ventriculography may be usefully combined with it in order to plan the most suitable operative approach for fenestration of membranes.

Growing numbers of people with learning disabilities are living longer and dying of age related illnesses such as cancer. To explore the experiences of people with learning disabilities who have cancer. The study used participant observation with 13 people with learning disabilities. All had a cancer diagnosis and 10 were terminally ill. Participants were visited regularly at home and in other settings, including hospitals. The main themes were: dependent lives; deprived lives; truth telling and understanding; the importance of families; inexperienced carers and unprepared services; and resilience. To understand the experiences of people with learning disabilities who are dying of cancer, it is important to understand their previous life experiences and key relationships. Healthcare professionals who treat people with respect, dignity and openness can make a positive difference to their care.

Full Text Available Mutations in Fibroblast Growth Factor Receptor II (FGFR2 have been identified in patients with Crouzon and Pfeiffer syndrome, among which rare mutations of the intracellular tyrosine kinase domain. Correlating subtle phenotypes with each rare mutation is still in progress. In Necker-Enfants Malades Hospital, we identified three patients harboring three different pathogenic variants of the same amino acid residue Asn-549 located in this domain: in addition to a very typical crouzonoid appearance, they all developed clinically relevant hydrocephalus, which is an inconstant feature of Crouzon and Pfeiffer syndrome. Overall, FGFR2 tyrosine kinase domain mutations account for 5/67 (7.4% cases in our hospital. We describe a novel mutation, p.Asn549Ser, and new cases of p.Asn549His and p.Asn549Thr mutations, each reported once before. Our three cases of Asn-549 mutations, alongside with rare previously reported cases, show that these patients are at higher risk of hydrocephalus. Clinical and imaging follow-up, with possible early surgery, may help prevent secondary intellectual disability.

2009-01-01

Objective: Radionuclide cerebrospinal fluid scintigraphy (RCFS) has been applied to make diagnosis of hydrocephalus clinically for a long time. This study aimed to evaluate clinical value of RCFS in guiding the management of patients with hydrocephalus. Methods: All 13 patients with hydrocephalus (8 adults, 5 children) underwent RCFS and CT/MRI examination before treatment and then follow-up imaging after treatment.Results: Four of 7 patients (6 adults, 1 child) diagnosed as obstructive hydrocephalus by RCFS underwent endoscopic third ventriculostomy (ETV), and 5 of 6 patients (2 adults, 4 children) diagnosed as obstructive hydrocephalus underwent ventriculo peritoneal shunt (VPS). All patients had good recovery after operation and favorable prognosis in follow-up for at least one year. Conclusion: RCFS could differentiate obstructive hydrocephalus from communicating hydrocephalus and had important guiding significance in the treatment of hydrocephalus. (authors)

Stoll, C; Alembik, Y; Dott, B; Roth, M P

1992-11-01

Risk factors were studied in 96 children with congenital hydrocephalus (CH) coming from 118,265 consecutive births of known outcome. Hydrocephalus with neural tube defects, intracranial tumors or secondary to brain atrophy were excluded. The prevalence of CH was 0.81 per thousand. Diagnosis was performed prenatally in 41 cases. Forty-three (44.8%) of the cases had hydrocephalus without other malformations (isolated hydrocephalus), 18 (18.7%) infants had recognized chromosomal or non-chromosomal syndromes and 35 children (36.4%) had multiple malformations. Each case was matched to a control. Weight and length at birth of children with hydrocephalus were less than in the controls (p pregnancy with a hydrocephalic child was more often complicated by threatened abortion, polyhydramnios and oligohydramnios. The mothers of children with hydrocephalus and multiple malformations had used oral contraceptives during the first trimester of pregnancy more often than the mothers of the controls. No differences appeared between the mothers of children with CH and the controls for the other risk factors studied: parental age, parity, previous pregnancies, previous stillbirths, smoking, diabetes, epilepsy, X-rays, hypertension, fever "flu", medication and occupational exposure. There was an increase of parental consanguinity in the parents of our patients (6.2% v. 1.1%, p < 0.001) and first degree relatives had more non-cerebral malformations than the controls (7.3% v. 3.2%, p < 0.05).

We report four patients with various types of hydrocephalus in whom constructive interference in steady state (CISS) MRI disclosed the cause of the hydrocephalus. The imaging clearly delineated an abnormal contour of the ventricular system and intraventricular septa, essential information for surgical planning, including endoscopic surgery. Postoperative CISS images were useful for showing not only regression of hydrocephalus but also the patency of small fenestrations. (orig.)

OBJECTIVE Hydrocephalus remains one of the more common pathologies managed in pediatric neurosurgical units. Endoscopic third ventriculostomy (ETV) has an advantage over ventriculoperitoneal shunting as it enables patients to remain device free. Multiple shunt devices with various valve designs exist, with no one valve proven to be superior to another. The aim of this study was to describe the management of hydrocephalus and its long-term outcome. METHODS The authors retrospectively reviewed the medical records of all patients who had been treated for hydrocephalus at the Hôpital Necker-Enfants Malades in the period from 1985 to 1995. RESULTS Nine hundred seventy-five children had been treated for hydrocephalus. The mean follow-up was 11 ± 7.4 years (mean ± standard deviation). The most common cause of hydrocephalus was tumor related (32.3%), followed by malformative (24.5%) and inflammatory (20.9%) causes. Two hundred eighty patients underwent ETV as the first-line treatment. The procedure was effective in controlling hydrocephalus due to posterior fossa tumors and aqueductal stenosis. Six hundred ninety-five children had initial shunt insertion, with the majority receiving an Orbis-Sigma valve (OSV). The overall OSV shunt survival was 70% at 1 year, 58% at 10 years, and 49% at 20 years. The most common cause for mechanical shunt failure was obstruction (50.7%). Overall shunt survival was statistically different between the OSV and the differential-pressure valve (p = 0.009). CONCLUSIONS Endoscopic third ventriculostomy is effective in the management of childhood hydrocephalus. Its success is directly related to the underlying pathology. In the long term, the OSV has significantly higher event-free shunt survival than the classic differential-pressure valve systems.

Classification of cerebrospinal fluid dynamics in hydrocephalus by computed tomographic cisternography

1980-01-01

Nine patients with normal CSF circulation and 49 patients with hydrocephalus of various etiologies were used to analyse the CSF dynamics by metrizamide CT cisternography. This investigation resulted in a new classification of CSF dynamics in both normal and hydrocephalic patients. We classified the patterns of CSF dynamics into seven types. Types I and II showed normal CSF kinetics, the former having no ventricular reflux, but the latter showing a transient ventricular reflux by 6 hours. The CSF dynamics in cases with communicating hydrocephalus was divided into types III, IV and V, according to the extent of ventricular filling and the convexity flow of the metrizamide. These types seen in communicating hydrocephalus were characterized by the presence of ventricular dilatation and persistent ventricular filling on 24 hours after the intrathecal injection of metrizamide. Type III showed more prominent flow into the convexity subarachnoid space than into the ventricular system. In Type IV the ventricular filling was almost the same extent as the convexity flow. Type V demonstrated a more prominent ventricular filling than convexity flow. Type VI had no intracranial entry of the metrizamide. Type VII, which represents the CSF kinetics in obstructive hydrocephalus, showed either a normal or delayed convexity flow. However no ventricular filling was present in spite of the marked ventricular enlargement. There was a close correlation between this new system of classification and the pathogenesis of hydrocephalus, as well as the various factors associated with the pathology of hydrocephalus. Our CT cisternographic classification of CSF dynamics seems to be of use in evaluating the grade of CSF circulation disturbance and in deciding the method of treatment of hydrocephalus. (author)

SNX27 Deletion Causes Hydrocephalus by Impairing Ependymal Cell Differentiation and Ciliogenesis.

Hydrocephalus is a brain disorder derived from CSF accumulation due to defects in CSF clearance. Although dysfunctional apical cilia in the ependymal cell layer are causal to the onset of hydrocephalus, mechanisms underlying proper ependymal cell differentiation are largely unclear. SNX27 is a trafficking component required for normal brain function and was shown previously to suppress γ-secretase-dependent amyloid precursor protein and Notch cleavage. However, it was unclear how SNX27-dependent γ-secretase inhibition could contribute to brain development and pathophysiology. Here, we describe and characterize an Snx27-deleted mouse model for the ependymal layer defects of deciliation and hydrocephalus. SNX27 deficiency results in reductions in ependymal cells and cilia density, as well as severe postnatal hydrocephalus. Inhibition of Notch intracellular domain signaling with γ-secretase inhibitors reversed ependymal cells/cilia loss and dilation of lateral ventricles in Snx27-deficient mice, giving strong indication that Snx27 deletion triggers defects in ependymal layer formation and ciliogenesis through Notch hyperactivation. Together, these results suggest that SNX27 is essential for ependymal cell differentiation and ciliogenesis, and its deletion can promote hydrocephalus pathogenesis. Down's syndrome (DS) in humans and mouse models has been shown previously to confer a high risk for the development of pathological hydrocephalus. Because we have previously described SNX27 as a component that is consistently downregulated in DS, we present here a robust Snx27-deleted mouse model that produces hydrocephalus and associated ciliary defects with complete penetrance. In addition, we find that γ-secretase/Notch modulation may be a candidate drug target in SNX27-associated hydrocephalus such as that observed in DS. Based on these findings, we anticipate that future study will determine whether modulation of a SNX27/Notch/γ-secretase pathway can also be of

Students identified with learning disabilities experience markedly lower levels of science and mathematics achievement than students who are not identified with a learning disability. Seemingly compounding their disadvantage, students with learning disabilities also complete more credits in non-core coursework-traditionally considered non-academic coursework-than students who are not identified with a learning disability. The Education Longitudinal Study of 2002, a large national dataset with both regular and special education high school students, is utilized to determine whether credit accumulation in certain types of non-core coursework, such as Technology and Communications courses, is associated with improved science and math course-taking outcomes for students with learning disabilities. Results show that credit accumulation in Technology and Communications coursework uniquely benefits the science course-taking, and comparably benefits the math course-taking, of students identified with learning disabilities in contrast to students who are not identified with a learning disability.

Nurses and other carers of people with learning disabilities must be able to manage choking events and perform basic life support effectively. UK guidelines for assessment of airway obstruction and for resuscitation do not take account of the specific needs of people with profound multiple learning disability. For example, they fail to account for inhibited gag and coughing reflexes, limited body movements or chest deformity. There are no national guidelines to assist in clinical decisions and training for nurses and carers. Basic life support training for students of learning disability nursing at Birmingham City University is supplemented to address these issues. The authors ask whether such training should be provided for all nurses including those caring for children and young people. They also invite comment and discussion on questions related to chest compression and training in basic life support for a person in a seated position.

Large vestibular schwannomas and hydrocephalus: Lessons learnt from a single centre experience

2014-01-01

Full Text Available Aim: The aim of the following study is to analyze the outcome following surgery in 169 patients with large vestibular schwannoma (VS and to evaluate hydrocephalus as a prognostic factor in patients of the VSs. Subjects and Methods: Retrospective analysis of all cases of VSs admitted to our tertiary neurosurgical center from January 2005 to December 2010 was performed. Comparison of patients who underwent pre-operative cerebrospinal fluid (CSF diversion and those who underwent primary surgery was carried out for post-operative complications and delayed hydrocephalus. Results: A total of 169 patients of VS were seen. The mean age at presentation was 39.03 years (12-72 years. The most common symptom was hearing loss seen in 161 (95.2% cases. Giant VS was seen in 130 (75.5% and hydrocephalus was present in 110 (63.9%. Pre-operative CSF diversion was done in 23 (13.1% patients; 8 (4.6% patients developed gradually symptomatic hydrocephalus following surgery and underwent ventriculoperitoneal shunt. Total surgical excision was done in 92.9% patients and subtotal excision was done in 7% patients. Conclusions: Hydrocephalus occurs in longstanding untreated cases of VS. Hydrocephalus causes no statistically significant increase in post-operative complications like CSF leak and post-operative hematoma. Patients with hydrocephalus presenting with acute symptoms of raised intracranial pressure benefit from CSF diversion. In most patients, tumor resection will restore patency of the CSF pathway and CSF diversion can be avoided.

Radionuclide cisternography in the diagnosis of hydrocephalus type in tuberculous meningitis in children

1993-01-01

The radionuclide cisternography permits an accurate diagnosis in hydrocephalus, this is an easy procedure, not traumatic nor expensive. Hydrocephalus is one of the most serious complications of tuberculous meningitis, that, without an opportune treatment, leads to severe sequel and death of the patient. The medical records of thirty patients with diagnosis of tuberculosis meningitis were reviewed, to whom the Neuro-Pediatric Service of the National Institute of Children Health solicited radionuclide cisternography to evaluate hydrocephalus and to determinate type, between january 1990 and october 1992. The hydrocephalus was demonstrated by radionuclide cisternography in 26/30 patients (86,7%) The most frequent age was in children under five years old 21/26 (80,7%) and pre-students in 65,38%. The most common finding was communicating hydrocephalus, pattern type IV in 20/30 patients (66,7%). It is concluded that the radionuclide cisternography is very useful for the diagnosis of hydrocephalus and its type patients with tuberculous meningitis. This exam is recommended for all patients with diagnosis of tuberculous meningitis, with no satisfactory evolution, in order to obtain an early diagnosis of hydrocephalus and its type, and get an opportune medical or surgical treatment.

Shim, Joon W.; Sandlund, Johanna; Hameed, Mustafa Q.; Blazer-Yost, Bonnie; Zhou, Feng C.; Klagsbrun, Michael; Madsen, Joseph R.

2016-01-01

Heparin binding epidermal growth factor-like growth factor (HB-EGF) is an angiogenic factor mediating radial migration of the developing forebrain, while vascular endothelial growth factor (VEGF) is known to influence rostral migratory stream in rodents. Cell migratory defects have been identified in animal models of hydrocephalus; however, the relationship between HB-EGF and hydrocephalus is unclear. We show that mice overexpressing human HB-EGF with β-galactosidase reporter exhibit an elevated VEGF, localization of β-galactosidase outside the subventricular zone (SVZ), subarachnoid hemorrhage, and ventriculomegaly. In Wistar polycystic kidney rats with hydrocephalus, alteration of migratory trajectory is detected. Furthermore, VEGF infusions into the rats result in ventriculomegaly with an increase of SVZ neuroblast in rostral migratory stream, whereas VEGF ligand inhibition prevents it. Our results support the idea that excess HB-EGF leads to a significant elevation of VEGF and ventricular dilatation. These data suggest a potential pathophysiological mechanism that elevated HB-EGF can elicit VEGF induction and hydrocephalus. PMID:27243144

Secondary pediatric encephalocele after ventriculosubgaleal shunting for posthemorrhagic hydrocephalus.

Science.gov (United States)

Seeburg, Daniel; Ahn, Edward; Huisman, Thierry

2014-08-01

Intraventricular hemorrhage and posthemorrhagic hydrocephalus continue to be common complications in very low-birth-weight premature infants, often requiring ventricular shunting for cerebrospinal fluid diversion. We report on two infants with posthemorrhagic hydrocephalus that developed a secondary encephalocele after ventriculosubgaleal shunting. Encephaloceles can act as a source of seizure activity and can result in various additional complications including meningitis, abscess formation, and infarction of herniated brain parenchyma. With continued improvements in neonatal intensive care, the survival of infants with significant medical comorbidities-including those that develop posthemorrhagic hydrocephalus requiring ventricular shunting-continues to increase. It is thus important for the radiologist and treating physician to be aware of this rare, potential complication. Georg Thieme Verlag KG Stuttgart · New York.

In all patients with NPH significant elevations of the apparent diffusion coefficients...... white matter, and in one patient reexamined one year after surgery, ADCs were unchanged in nearly all brain regions. The increased ADC values in hydrocephalus patients may be caused by factors such as changes in myelin-associated bound water, increased Virchow-Robin spaces, and increased extracellular...... brain water fraction.

Fujiwara, Hidemoto; Aiba, Toyotaka; Watanabe, Toru; Hiraishi, Tetsuya; Fujii, Yukihiko

2016-12-01

Small meningiomas causing hydrocephalus without obstruction of the ventricular system are rare. Herein, we report a case of small clinoidal meningioma with communicating hydrocephalus, which resolved after tumor removal. A 70-year-old woman presented with a 1-month history of memory disturbance followed by gait disturbance. MR images revealed a right clinoidal meningioma, 2 cm in diameter, and dilatation of the ventricles suggesting communicating hydrocephalus. The cerebrospinal fluid(CSF)pressure was 130 mmH2O, as determined via a lumbar puncture. High concentrations of protein(65mg/dL)were detected in the lumbar CSF. The tumor was completely removed via a frontotemporal craniotomy. Higher protein concentrations(94mg/dL)were detected in the CSF obtained intraoperatively from the sylvian cistern. The histopathological diagnosis was meningothelial meningioma. The patient's symptoms improved markedly after surgery. Postoperative MR images revealed resolution of the hydrocephalus. The lumbar CSF protein concentration returned to normal(43mg/dL). Neither tumor recurrence nor progression of hydrocephalus has been observed for 4 years. Communicating hydrocephalus, associated with a small meningioma at the supratentorial region, has not been described. Previous studies have shown that patients with meningioma may develop communicating hydrocephalus after tumor removal or stereotactic radiosurgery. Thus, it is interesting that the small supratentorial meningioma in our case developed communicating hydrocephalus without any therapeutic intervention. Considering the CSF protein concentration, we speculate that the hydrocephalus was the result of CSF malabsorption associated with high CSF protein concentration and CSF pathway obstruction at the suprasellar cistern caused by the tumor.

Concept and treatment of hydrocephalus in the Greco-Roman and early Arabic medicine.

Science.gov (United States)

Grunert, P; Charalampaki, P; Ayyad, A

2007-10-01

In the ancient medical literature hydrocephalus was not often described although its existence and symptomatology were well known. Most detailed descriptions of hydrocephalus including the surgical treatment are extant in the encyclopaedic works on medicine of the physicians Oreibasios and Aetios from Amida from the 4th and 6th centuries AD, respectively. Because of their broad scientific interests, this type of physicians, typical for the late Roman empire, were known as philosophy-physicians (iota alpha tau rho o sigma o phi iota sigma tau alpha iota). They defined hydrocephalus in contrast to our present understanding as a fluid collection excluding abscesses visible as a bulging tumour localised either outside or inside the skull of an infant. They classified the hydrocephalus similar as stated first by Galen in the 2nd century AD in four types corresponding to the assumed anatomic localisation of the fluid collection: 1st Type between the skin and the pericranium corresponding to the subgaleal haematoma or caput succedaneum of the newborn in our terminology, 2nd Type between the pericranium and the skull corresponding to the cephal haematoma after delivery, 3rd Type between skull and the meninges with increased head circumference, bone sutures being increasingly driven apart corresponding most likely to the hydrocephalus in our understanding, and 4th Type between the menings and the brain characterised by severe neurological deficit with lethal prognosis corresponding probably to all pathologies which were accompanied by an excessive increase of the intracranial pressure with a bulging fontanel. Due to the lack of autopsies in ancient times, the hydrocephalus was never linked to the pathology of the ventricles. All forms of hydrocephalus were believed to be caused by improper handling of the head by the midwife during delivery. Only the extracranial fluid collections, but not hydrocephalus in our sense, were considered to be suitable for surgical treatment

Recent research has focused on the role of self-esteem and self-handicapping strategies in the school domain. Self-handicapping refers to maladaptive strategies employed by adults and children for protection and maintenance of positive school self esteem. In this study the self-esteem and the self-handicapping strategies of children with dyslexia, reading comprehension disabilities, and mathematical disabilities were compared to a control group with normal learning. There were 56 children whose mean age was 8 (23 girls, 33 boys), attending Grade 3 of primary school. These pupils were selected by scores on a battery of learning tests commonly used in Italy for assessment of learning disabilities. Analyses suggested these children with dyslexia, reading comprehension disabilities, and mathematical disabilities had lower ratings of self-esteem at school and employed more self-handicapping strategies than did children whose learning was normal. More research is required to identify and examine in depth the factors that promote adaptive strategies to cope with children's reading difficulties.

This qualitative phenomenological study explores the lived experiences of perceived support by Iranian mothers who have children with learning disability. Twelve open interviews with six mothers of learning-disabled children (7-12 years of age) were audiotape-recorded with participants' consent. The interviews were transcribed and data were analyzed using Van Manen methodology. Two major themes emerged from 138 thematic sentences. The mothers'experiences could be interpreted as a sense of being in the light or being in the shade of support, with variations for different participants. The results indicate a need for more specialized and individually adjusted support for mothers in Iran.

Full Text Available The treatment of hydrocephalus has undergone remarkable transformation since it was first documented over two thousand years ago. Currently, the focus of hydrocephalus research is on minimally invasive techniques of treatment. This article reviews the evolution of hydrocephalus therapy, and examines current attitudes towards modern methods. We relied on journal publications, as well as literature on hydrocephalus obtained from the Internet (Google, Yahoo and PUBMED search making use of the following search terms: “hydrocephalus: history; treatment; complications”, “cerebrospinal fluid shunt”, “endoscopic third ventriculostomy: indications of; complications of; advantages; disadvantages; successes; failure”. Numerous medical and surgical approaches have been adopted in the treatment of hydrocephalus in the past. However, the breakthrough that ushered in the modern era of hydrocephalus treatment was the introduction of valve-regulated systems in the middle of the last century. Endoscopic third ventriculostomy has evolved to become an alternative to traditional shunts. Cerebrospinal fluid shunt procedures are very effective in the treatment of hydrocephalus and have radically transformed the outcome of the disorder. However, they have a number of limitations. The alternative to shunts, endoscopic third ventriculostomy, is relatively safe, effective and durable. It does not, however, succeed in every patient; and also has some potentially devastating complications. Preoperative counseling is imperative to ensure that patients are properly guided.

Benign external hydrocephalus is defined as a rapidly increasing head circumference (occipitofrontal circumference) with characteristic radiological findings of increased subarachnoid cerebrospinal fluid spaces on neuroimaging. The incidence of benign external hydrocephalus has not been previously reported, and there is no available information on the ratio of benign external hydrocephalus in the population of hydrocephalic children. This study is retrospective and population-based study, geographically covering two health regions in the southern half of Norway with a total mean population of 3.34 million in the ten-year study period, constituting approximately 75% of the Norwegian population. Children with a head circumference crossing two percentiles, or greater than the 97.5th percentile, and with typical imaging findings of enlarged frontal subarachnoid spaces with or without enlarged ventricles were included. Children were excluded if they had a history of head trauma, intracranial hemorrhage, central nervous system infection, other known causes of hydrocephalus, or were born preterm defined as birth before 37 weeks of gestation. A total of 176 children fitting the criteria were identified, giving an incidence of 0.4 per 1000 live births. One hundred fifty-two (86.4%) of the patients were male, and mean age at referral was 7.3 months. Increasing head circumference was the main reason for referral in 158 (89.8%) patients and the only finding in 60 (34.1%) patients. Thirty-seven (21%) children had normal ventricles on imaging; the remainder had increased ventricular size. The incidence of pediatric hydrocephalus in Norway is reported to be 0.75 per 1000 live births, thus benign external hydrocephalus accounts for approximately 50% of hydrocephalic conditions in this population. The incidence of benign external hydrocephalus was found to be 0.4 per 1000 live births in this population. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights

Full Text Available "nGerminal matrix-intraventricular hemorrhage (IVH is the most common variety of neonatal intracranial hemorrhage and is characteristics of the premature infant. The importance of the lesion relates not only to its high incidence but to their attendant complications (IC: hydrocephalus. Brain sonography is the procedure of choice in diagnosis of germinal matrix- intraventricular hemorrhage and hydrocephalus. In this study we have used brain sonography for detection of intraventricular hemorrhage and post hemorrhagic hydrocephalus and their incidences. The studied population was consisted of premature neonate (birth weight equal or less than 1500g and gestational age equal or less than 37 weeks who admitted in Mofid Hospital NICU (Tehran, Iran during a one year period. For all neonate (including criteria brain sonography in first week of life was done and in presence of IVH, serial Brain sonography was done weekly for detection of hydrocephalus. A total of 57 neonate entered the study. Intraventicular-germinal matrix hemorrhage was seen in 64.4% (35 patients. Forty percent of patients with intraventricular-germinal matrix hemorrhage had grade I, 11% grade II, 25.7% grade III, 2.8% grade VI. Hydrocephalus was detected in 20 percent of patients who had intraventricular-germinal matrix hemorrhage. That incidence of IVH in our study in comparison with other area and situation is higher. Hydrocephaly had direct relation with severity of IVH. This shows that with control of risk factor of IVH, we can control Post hemorrhagic hydrocephalus.

Radionuclide cisternography in diagnostics of obstruction hydrocephalus in introduced ventricculoperitoneal shunt

2004-01-01

To confirm or exclude a diagnosis of internal obstruction hydrocephalus in an 8-year old girl with an introduced ventriculoperitoneal (V-P) shunt Establishing the V-P shunt is indisputably the route of choice in non-communicating hydrocephalus. The existence of a V-P shunt, however, is connected with numerous risks, especially of injuries, infection as well as increased intraabdominal pressure - e.g. in pregnancy. The development of endoscopy in neurosurgery allows the creation of communication via the bottom of the third ventricle with basal cisterns, and the subsequent cancellation of a V-P shunt. We describe the case of an 8-year old girl with congenital internal hydrocephalus with an assumed obliteration of the Sylvian aqueduct with an established V-P shunt. An MR scan described the membrane in the area of the Sylvian aqueduct, but the disproportion between the dilatation of the lateral ventricles, third ventricle and fourth ventricle led the physician to doubt as to the accuracy of the diagnosis of internal obstruction hydrocephalus. Therefore we performed a radionuclide cisternography (in a modified manner), which proved an existing communication between the third and fourth cerebral ventricle and which contradicted the clinical diagnosis of obstruction hydrocephalus.

Spontaneous ventriculostomy is spontaneous rupture of membranes separating the ventricular system from the subarachnoid space in patients with chronic obstructive hydrocephalus that ends with resolution of symptoms. We present a case of spontaneous third ventriculostomy occurred in a 19-year-old girl 8 years after the initial diagnosis of hydrocephalus. An 11-year-old girl applied to the clinic with intermittent headaches. She was neurologically stable with no visual problems. On her brain MRI, obstructive hydrocephalus was observed. Cerebrospinal fluid diversion procedures were recommended, yet the family denied any interventional procedure. She had routine follow-ups with occasional clinical admissions because of ongoing intermittent headaches. On her last clinical visit, 8 years after the first one, she was in well condition with improvement in her headache in the last 4 months. Her new brain MRI showed an active CSF flow between the basal cistern and the third ventricle. In patients with aqueductal stenosis and without any other mass lesion, wait and see protocol might be conveyed in case of mild symptoms of hydrocephalus. However, there is need for large-scaled studies to make a more comprehensive statement for benign obstructive hydrocephalus cases.

Cogenital hydrocephalus is caused by a broad spectrum of underlying disorders. In the majority of cases it is due to aqueductal stenosis and other distinct congenital anomalies, like Arnold-Chiari malformation. Nevertheless, in the differential diagnosis rare conditions such as cerebral malignancies must also be considered. We present two cases of congenital intracerebral teratoma as a differential diagnosis in congenital obstructive hydrocephalus. A teratoma is suggested when a rapidly growing hydrocephalus with a central calcified and vascularized mass is found sonographically. Regular cerebral structures using cannot be detected. Early diagnosis in such cases is of clinical importance as the prognosis of congential intracerebral teratoma is generally very poor. (orig.)

The digital age has reached early childhood, and the use of touch screens by young children is common place. Research on the use of touch screen tablets with young children is becoming more prevalent; however, less information is available on the use of touch screen tablets to support young children with disabilities. Touch screen tablets may offer possibilities to preschool children with disabilities to participate in learning in a digital way. The iPad provides easy interaction on the touch screen and access to a multitude of engaging early learning applications. This paper summarizes a pilot study with 8 young children with disabilities included in a preschool classroom, who were given iPads to use in class and at home for a period of 21 weeks. Systematic observations, classroom assessments, and teacher and parent interviews documented the improvements in learning outcomes for each child in many areas including, but not limited to: shape and color recognition, letter recognition, and tracing letters throughout six research cycles.

The glymphatic system has in previous studies been shown as fundamental to clearance of waste metabolites from the brain interstitial space, and is proposed to be instrumental in normal ageing and brain pathology such as Alzheimer's disease and brain trauma. Assessment of glymphatic function using magnetic resonance imaging with intrathecal contrast agent as a cerebrospinal fluid tracer has so far been limited to rodents. We aimed to image cerebrospinal fluid flow characteristics and glymphatic function in humans, and applied the methodology in a prospective study of 15 idiopathic normal pressure hydrocephalus patients (mean age 71.3 ± 8.1 years, three female and 12 male) and eight reference subjects (mean age 41.1 + 13.0 years, six female and two male) with suspected cerebrospinal fluid leakage (seven) and intracranial cyst (one). The imaging protocol included T1-weighted magnetic resonance imaging with equal sequence parameters before and at multiple time points through 24 h after intrathecal injection of the contrast agent gadobutrol at the lumbar level. All study subjects were kept in the supine position between examinations during the first day. Gadobutrol enhancement was measured at all imaging time points from regions of interest placed at predefined locations in brain parenchyma, the subarachnoid and intraventricular space, and inside the sagittal sinus. Parameters demonstrating gadobutrol enhancement and clearance in different locations were compared between idiopathic normal pressure hydrocephalus and reference subjects. A characteristic flow pattern in idiopathic normal hydrocephalus was ventricular reflux of gadobutrol from the subarachnoid space followed by transependymal gadobutrol migration. At the brain surfaces, gadobutrol propagated antegradely along large leptomeningeal arteries in all study subjects, and preceded glymphatic enhancement in adjacent brain tissue, indicating a pivotal role of intracranial pulsations for glymphatic function.

Feeding and swallowing impairments are key predictors of increased morbidity and mortality in adults with learning disabilities. This postal survey and interview study sought to identify risk factors in adults with learning disabilities who have histories of choking. A total of 2000 questionnaires were sent to carers of all adults with learning disabilities registered as service users by three local health authorities. (A 'service user' may be using any specialist learning disability health or social care facility with day, residential or therapeutic services). Of the 674 service users for whom surveys were returned, 47 were living in hospital, 396 were living in residential or group homes and 208 were living with relatives, or in their own homes. Eighteen subjects who had reported serious or repeated episodes of choking were interviewed in depth in their residences or workplaces. Responses were subjected to frequency analyses. Personal characteristics were analysed. Choking patterns were differentiated by food texture. A total of 34% of questionnaires on 674 service users were returned; 42% of respondents reported one or more choking episodes. There was a significantly greater occurrence of choking among people with more severe learning disability, with Down syndrome, people who had an incomplete dentition or were taking a greater number of psychotropic drugs. Antisocial eating habits learnt in institutional settings presented an additional choking hazard for some individuals. Choking is a serious hazard for many adults with learning disabilities. This study establishes many of the characteristics associated with swallowing problems in this population. Clinicians and carers should benefit from awareness of these predictors, leading to better management of eating behaviours and habits. A choking and swallowing risk assessment should be included in routine health assessments of adults with learning disability, paying especial attention to the condition of a person

To compare self-esteem and maternal attitude between children with learning disability and their unaffected siblings. This cross sectional study was conducted at a tertiary care hospital in an urban setting. It comprised of 31 pairs of children with a learning disability, their unaffected siblings and input from their mothers. All children were assessed with Rosenberg self-esteem scale. Mothers were asked to fill Index of parental attitude (IPA) and semi structured proforma with demographic data and questionnaire about her children with a learning disability and his/her unaffected sibling. Self-esteem was found to be lower in children with learning disability. They felt they do not have much to be proud of and have a fewer number of good qualities. They are also inclined to consider themselves as failures. In factors affecting self-esteem, index of parental attitude was found to be unfavorable towards children with learning disability. Mothers felt child was interfering with their activities and was getting on their nerves. In addition, they also felt that they do not understand their child, feel like they do not love their child and wished that child was more like others they know off. More academic failures, academic difficulties and negative school report were also perceived by mother as lowering child's self-esteem. Self-esteem was lower in children with learning disability. In factors affecting self-esteem maternal attitude, academic difficulties, academic failure and negative school reports was found to be unfavorable.

Hydrocephalus and mucopolysaccharidoses: what do we know and what do we not know?

Science.gov (United States)

Dalla Corte, Amauri; de Souza, Carolina F M; Anés, Maurício; Giugliani, Roberto

2017-07-01

The precise incidence of hydrocephalus in patients with mucopolysaccharidoses (MPS) is hard to determine, because the condition lacks a formal, consensus-based definition. The diagnosis of hydrocephalus depends on symptom profile, presence of neuroimaging features, and the outcome of diagnostic tests. Although numerous techniques are used to identify MPS patients who are most likely to have hydrocephalus and respond to treatment, no definitive method exists to prove diagnosis. The authors propose an algorithm to aid in the diagnosis and management of hydrocephalus in MPS patients. The theory of venous hypertension associated with the morphological changes in the skull base and craniocervical junction indicate the need for future neuroimaging studies including cerebrospinal fluid (CSF) and venous flow measurements to monitor hydrocephalus progression and select therapeutic interventions in MPS patients. Preoperative planning should also be based on the increased risk of intraoperative and postoperative hemorrhagic complications.

Purpose: to investigate whether diffusion-weighted imaging (DWI) in magnetic resonance imaging (MRI) provides additional information about the periventricular white matter for the assessment of hydrocephalus. Materials and methods: sixteen MRI examinations (11 with acutely increased cerebral pressure, 5 without symptoms) on 15 patients with hydrocephalus (4 patients with communicating hydrocephalus and 11 patients with obstructive hydrocephalus) were analyzed. One symptomatic patient subsequently became asymptomatic. We investigated the ''apparent diffusion coefficient'' (ADC) in the subcortical and periventricular white matter. The ADCs of the study patients were compared with those of a healthy control group. Results: symptomatic patients with hydrocephalus, 6/11 showed periventricular edema and a significantly higher ADC values in the periventricular region than in the subcortical white matter. 5/11 symptomatic patients showed significantly higher ADC values even in the absence of periventricular interstitial edema (both groups contained patients with communicating and obstructive hydrocephalus). All 5 asymptomatic patients with hydrocephalus did not have a significantly higher ADC values in the periventricular region. Conclusion: in patients with hydrocephalus and acutely increased cerebral pressure, DWI showed a significantly higher ADC values in the periventricular region even without visible interstitial edema on conventional MRI sequences.

Thomas, P R; DeAlwis, K

1995-10-01

A case of transvestism is reported in a 47-year-old man with learning disabilities. He had developed encephalitis in childhood, which had resulted in moderate learning disabilities and epilepsy, and had been living in institutions from the age of six. He did not have any chance to express his sexual desire and this frustration manifested as aggressive behaviour. Recently, he moved to a community home and his deviant sexual behaviour became apparent. Management of his problems involves organizing a behavioural programme linking his cross dressing with aggressive behaviour.

Aqueductal stenosis is the commonest cause of congenital hydrocephalus. The scope of this paper is to highlight the disease burden of hydrocephalus attributed to aqueductal stenosis which still remains unknown in our setting. In a descriptive cross-sectional study, 258 records of patients diagnosed with hydrocephalus were analyzed after ethical approval from Kenyatta National Hospital- University of Nairobi (KNH-UON) ethics and research committee from January 2010 to May 2016. Patients with a diagnosis of hydrocephalus due to aqueductal stenosis were included in this study. Patients age, sex, mode of delivery, associated comorbidities, presenting complaints, neurosurgical intervention performed, Kafarnosky score were recorded. Data were divided into 2 sets based on the patient's age i.e. whether 12 years. Data were recorded on google data collection form and analyzed using Google spreadsheets. Out of 258 cases of hydrocephalus, 52 had aqueductal stenosis. Male to female sex ratio for this condition was 3:2. There were 25 cases 12 years old who were diagnosed with hydrocephalus due to aqueductal stenosis. Associated conditions were bilateral congenital talipes equinovarus, spina bifida, Arnold Chairi malformations, meningitis and HIV. The presenting complaints differed according to the age groups. Neurosurgical interventions included Endoscopic Third Ventriculostomy (ETV) in 21 cases, insertion of Ventriculoperitoneal (VP) shunt and ETV were done in 3 cases while the rest had only insertion of VP shunt. The Kafanosky score improve from hydrocephalus. Clinical presentation differs according to patients age. Accurate diagnosis and treatment remain a cardinal to improving patient outcome.

Adult sibling experience, roles, relationships and future concerns - a review of the literature in learning disabilities.

Davys, Deborah; Mitchell, Duncan; Haigh, Carol

2011-10-01

This paper provides a review of the literature related to adult siblings of learning-disabled people. Siblings of learning-disabled people are often looked upon as next of kin when older parents die; however, there is little research regarding sibling views and wishes. A literature review of published peer-reviewed empirical research was undertaken. Electronic databases and citation tracking were used to collate data using key terms such as adult siblings and learning disability. Relevant articles were analysed, compared and contrasted. Six key themes emerged suggesting a varied impact of learning disability upon sibling lives in areas that include life choices, relationships, identity and future plans. Some siblings report a positive impact upon life, others state their lives are comparable with other adults who do not have a learning-disabled sibling and others still report a negative impact. Sibling roles and relationships are varied. Evidence suggests that sibling roles, relationships and experience are affected by life stage. Parents often have a primary care role for the disabled person, whilst siblings perform a more distant role; however, sibling involvement often rises when parents are no longer able to provide previous levels of support. Many factors appear to affect the sibling experience and uptake of roles including gender, life stage and circumstances, level of disability, health status and relationships between family members. Siblings are concerned about the future, particularly when parents are no longer able to provide support, and many appear to have expectations of future responsibilities regarding their disabled sibling. As siblings of people who have a learning disability are often expected by society to provide support, it is important that health and social care practitioners are aware of issues that may impact on this relationship. © 2011 Blackwell Publishing Ltd.

BACKGROUND: Implant infection and obstruction are major complications for ventriculoperitoneal shunts in patients with post-haemorrhagic hydrocephalus. In an effort to (1) reduce the incidence of these complications, (2) reduce the rate of shunt failure and (3) shorten the duration of neurosurgical...... hospitalisation, we have implemented valveless ventriculoperitoneal shunts at our department for adult patients with post-haemorrhagic hydrocephalus and haemorrhagic cerebrospinal fluid at the time of shunt insertion. METHODS: All adult patients (>18 years old) treated for post-haemorrhagic hydrocephalus.......3 %, p = 0.02), but a higher rate of overdrainage (10.3 % vs 2.6 %, p = 0.04). CONCLUSION: The use of a valveless shunting for patients with post-haemorrhagic hydrocephalus results in shorter duration of neurosurgical hospitalisation and lower rate of shunt infection, although these advantages should...

Abdul Naveed Khan

2017-01-01

Full Text Available BACKGROUND: To describe the structure and efficacy of a modified cerebrospinal fluid (CSF shunt system with Bhatti CSF access chamber and ventriculoperitoneal shunt, for the management of hydrocephalus associated with pyogenic ventriculitis. METHODS: This was an observational study performed at the National Medical Center and Ziauddin Medical University, Karachi, Pakistan. Chemically bonded Bhatti CSF access chamber and ventriculoperitoneal shunt was inserted into 443 patients with hydrocephalus and pyogenic ventriculitis to allow injection of antibiotics into the lateral ventricles. RESULTS: In all patients, symptoms and signs of hydrocephalus were relieved immediately after shunt insertion and infection brought under control within two weeks of intraventricular injection of antibiotics (vancomycin or linezolid, via the CSF access chamber. In two patients peritoneal catheter was blocked by a precipitate of vancomycin. Reduction in the dose of intraventricular vancomycin from 50mg to 20mg and increased dilution (additional 2ml of 0.9% N/S solution prevented recurrence of this complication. All patients recovered from ventriculitis within two weeks of initiating this treatment. Follow-up was from 3 months to 2 years to monitor continued relief of hydrocephalus and absence of recurrence of ventriculitis. CONCLUSION: Bhatti CSF access chamber and the ventriculoperitoneal shunt is the only system available at present that fulfills the management of hydrocephalus associated with pyogenic ventriculitis. It provides continuous internal drainage of CSF combined with access to the ventricles for injection of antibiotics.

2011-09-01

A 37-year-old female yellow-headed Amazon parrot (Amazona ochrocephala oratrix) was presented after a 4-month-period behavior change and intermittent episodes of obtunded mentation. Clinical findings on physical examination included ataxia, a weak grasp, and reluctance to move. Results of magnetic resonance imaging were consistent with severe hydrocephalus without evidence of cerebrospinal fluid obstruction. The bird was treated with tapering dosages of prednisolone over a 4-month period, during which time the episodes did not occur. Discontinuation of treatment was attempted several times but resulted in relapse. After 3.5 years of maintenance treatment with prednisolone, the bird was presented subsequent to a 5-hour episode of obtunded mentation and worsening neurologic signs. Despite increasing the dose of prednisolone and providing additional supportive care, the bird's condition worsened, and euthanasia was elected. Necropsy findings included severe hydrocephalus with significant loss of right cerebral parenchyma and no evidence of cerebrospinal fluid obstruction. Histologic examination of the remaining cerebral parenchyma revealed a moderate, multifocal, cellular infiltrate; encephalomalacia; fibrosis; and hemosiderosis in tissue adjacent to the distended ventricles. Other findings included hepatic vacuolar degeneration. Diagnostic imaging and postmortem findings were consistent with a diagnosis of hydrocephalus ex vacuo. To our knowledge, this is the first report of hydrocephalus in an Amazon parrot as well as the first report of hydrocephalus in any avian species associated with long-term follow-up and prolonged corticosteroid treatment.

Stereotactic CO2 laser therapy for hydrocephalus

Kozodoy-Pins, Rebecca L.; Harrington, James A.; Zazanis, George A.; Nosko, Michael G.; Lehman, Richard M.

1994-05-01

A new fiber-optic delivery system for CO2 radiation has been used to successfully treat non-communicating hydrocephalus. This system consists of a hollow sapphire waveguide employed in the lumen of a stereotactically-guided neuroendoscope. CO2 gas flows through the bore of the hollow waveguide, creating a path for the laser beam through the cerebrospinal fluid (CSF). This delivery system has the advantages of both visualization and guided CO2 laser radiation without the same 4.3 mm diameter scope. Several patients with hydrocephalus were treated with this new system. The laser was used to create a passage in the floor of the ventricle to allow the flow of CSF from the ventricles to the sub-arachnoid space. Initial postoperative results demonstrated a relief of the clinical symptoms. Long-term results will indicate if this type of therapy will be superior to the use of implanted silicone shunts. Since CO2 laser radiation at 10.6 micrometers is strongly absorbed by the water in tissue and CSF, damage to tissue surrounding the lesion with each laser pulse is limited. The accuracy and safety of this technique may prove it to be an advantageous therapy for obstructive hydrocephalus.

Treatment of pediatric hydrocephalus in sub-Saharan countries is associated with significant complication rates. The objective of this study is to analyze the management of hydrocephalus and complication rates of surgical intervention in the Ethiopian setting to improve future quality. A retrospective cohort study was conducted in a neurosurgical teaching hospital. Two cohorts separated by 2.5 years were analyzed. A total of 128 (58.6% male and 41.4% female) children with isolated hydrocephalus, meningomyelocele (MMC)-related hydrocephalus, or MMC without hydrocephalus were included. Their age ranged from 1 day to 5 years, for a mean age of 7.2 months (median age 2 months). One hundred thirteen patients had hydrocephalus, of whom 57 (44.5.3%) had isolated hydrocephalus and 56 (43.8%) had hydrocephalus associated with MMC. Seventy-seven (74.7%) patients underwent ventriculoperitoneal (VP) shunting, whereas 24 (23.3%) underwent endoscopic third ventriculostomy (ETV). The incidence of shunt infection was 23.4%. Reoperation was needed in 54 (52.4%) patients, with the most common indication being shunt failure. ETV failed in 14 (58.3%) of the 24 patients undergoing ETV. VP shunt insertions had unacceptably high infection rate despite the presence of a protocol for the procedure. Intraoperative guidelines should be developed further and followed strictly to reduce infections. Such measures should include restricting the number of surgeons performing the procedure. In our opinion, one should avoid insertion of a VP shunt as the primary treatment. ETV has proved to be a good alternative in other studies and the decreasing pattern of ETV failure in our study also suggest ETV as a better alternative to VP shunt. Copyright © 2016 The Author(s).

Emotional false memories in children with learning disabilities.

Mirandola, Chiara; Losito, Nunzia; Ghetti, Simona; Cornoldi, Cesare

2014-02-01

Research has shown that children with learning disabilities (LD) are less prone to evince associative illusions of memory as a result of impairments in their ability to engage in semantic processing. However, it is unclear whether this observation is true for scripted life events, especially if they include emotional content, or across a broad spectrum of learning disabilities. The present study addressed these issues by assessing recognition memory for script-like information in children with nonverbal learning disability (NLD), children with dyslexia, and typically developing children (N=51). Participants viewed photographs about 8 common events (e.g., family dinner), and embedded in each episode was either a negative or a neutral consequence of an unseen action. Children's memory was then tested on a yes/no recognition task that included old and new photographs. Results showed that the three groups performed similarly in recognizing target photographs, but exhibited differences in memory errors. Compared to other groups, children with NLD were more likely to falsely recognize photographs that depicted an unseen cause of an emotional seen event and associated more "Remember" responses to these errors. Children with dyslexia were equally likely to falsely recognize both unseen causes of seen photographs and photographs generally consistent with the script, whereas the other participant groups were more likely to falsely recognize unseen causes rather than script-consistent distractors. Results are interpreted in terms of mechanisms underlying false memories' formation in different clinical populations of children with LD. Copyright © 2013 Elsevier Ltd. All rights reserved.

Morphological and Behavioral Changes in the Pathogenesis of a Novel Mouse Model of Communicating Hydrocephalus

Science.gov (United States)

McMullen, Allison B.; Baidwan, Gurlal S.; McCarthy, Ken D.

2012-01-01

The Ro1 model of hydrocephalus represents an excellent model for studying the pathogenesis of hydrocephalus due to its complete penetrance and inducibility, enabling the investigation of the earliest cellular and histological changes in hydrocephalus prior to overt pathology. Hematoxylin and eosin staining, immunofluorescence and electron microscopy were used to characterize the histopathological events of hydrocephalus in this model. Additionally, a broad battery of behavioral tests was used to investigate behavioral changes in the Ro1 model of hydrocephalus. The earliest histological changes observed in this model were ventriculomegaly and disorganization of the ependymal lining of the aqueduct of Sylvius, which occurred concomitantly. Ventriculomegaly led to thinning of the ependyma, which was associated with periventricular edema and areas of the ventricular wall void of cilia and microvilli. Ependymal denudation was subsequent to severe ventriculomegaly, suggesting that it is an effect, rather than a cause, of hydrocephalus in the Ro1 model. Additionally, there was no closure of the aqueduct of Sylvius or any blockages within the ventricular system, even with severe ventriculomegaly, suggesting that the Ro1 model represents a model of communicating hydrocephalus. Interestingly, even with severe ventriculomegaly, there were no behavioral changes, suggesting that the brain is able to compensate for the structural changes that occur in the pathogenesis of hydrocephalus if the disorder progresses at a sufficiently slow rate.

2017-05-01

Full Text Available The digital age has reached early childhood, and the use of touch screens by young children is common place. Research on the use of touch screen tablets with young children is becoming more prevalent; however, less information is available on the use of touch screen tablets to support young children with disabilities. Touch screen tablets may offer possibilities to preschool children with disabilities to participate in learning in a digital way. The iPad provides easy interaction on the touch screen and access to a multitude of engaging early learning applications. This paper summarizes a pilot study with 8 young children with disabilities included in a preschool classroom, who were given iPads to use in class and at home for a period of 21 weeks. Systematic observations, classroom assessments, and teacher and parent interviews documented the improvements in learning outcomes for each child in many areas including, but not limited to: shape and color recognition, letter recognition, and tracing letters throughout six research cycles.

The Monros of the University of Edinburgh reigned over anatomy instruction for over a century. The last of these men, Monro Tertius, was the weaker teacher of the family but still contributed to the anatomical and surgical literature. Herein, we describe the life of Alexander Monro Tertius and his writings, particularly on childhood hydrocephalus. Monro Tertius will not be remembered as a great anatomist or teacher. However, he collected and published important books on his observations and those of others on hydrocephalus. These texts contained the knowledge of his era on this topic.

Early Foundations for Mathematics Learning and Their Relations to Learning Disabilities.

Science.gov (United States)

Geary, David C

2013-02-01

Children's quantitative competencies upon entry into school can have lifelong consequences. Children who start behind generally stay behind, and mathematical skills at school completion influence employment prospects and wages in adulthood. I review the current debate over whether early quantitative learning is supported by (a) an inherent system for representing approximate magnitudes, (b) an attentional-control system that enables explicit processing of quantitative symbols, such as Arabic numerals, or (c) the logical problem-solving abilities that facilitate learning of the relations among numerals. Studies of children with mathematical learning disabilities and difficulties have suggested that each of these competencies may be involved, but to different degrees and at different points in the learning process. Clarifying how and when these competencies facilitate early quantitative learning and developing interventions to address their impact on children have the potential to yield substantial benefits for individuals and for society.

2012-01-01

Full Text Available In this study, children with a mathematical learning disability (=14 and age-matched peers without learning disabilities (=14 as well as their parents and teachers were interviewed on how they experienced playing an instrument (guitar, drum, flute, violin, trombone, horn, and piano and on what helped them using a qualitative interactive interview with a flexible agenda to discover the interviewee’s own framework of meanings. Thematic analyses mentioned intrinsic motivation, extrinsic motivation, and self-efficacy as important. Some children with MLD were found to have a real musical talent and a very good musical ear and memory for sounds. However, all children with MLD seemed more dependent on the aid of parents, sibling, peers, and teachers. They had to study harder and needed more time to study, more practice, and a more structured approach.

Longitudinal mathematics development of students with learning disabilities and students without disabilities: a comparison of linear, quadratic, and piecewise linear mixed effects models.

2015-04-01

Effective instructional planning and intervening rely heavily on accurate understanding of students' growth, but relatively few researchers have examined mathematics achievement trajectories, particularly for students with special needs. We applied linear, quadratic, and piecewise linear mixed-effects models to identify the best-fitting model for mathematics development over elementary and middle school and to ascertain differences in growth trajectories of children with learning disabilities relative to their typically developing peers. The analytic sample of 2150 students was drawn from the Early Childhood Longitudinal Study - Kindergarten Cohort, a nationally representative sample of United States children who entered kindergarten in 1998. We first modeled students' mathematics growth via multiple mixed-effects models to determine the best fitting model of 9-year growth and then compared the trajectories of students with and without learning disabilities. Results indicate that the piecewise linear mixed-effects model captured best the functional form of students' mathematics trajectories. In addition, there were substantial achievement gaps between students with learning disabilities and students with no disabilities, and their trajectories differed such that students without disabilities progressed at a higher rate than their peers who had learning disabilities. The results underscore the need for further research to understand how to appropriately model students' mathematics trajectories and the need for attention to mathematics achievement gaps in policy.

Ventriculosubgaleal shunts for posthemorrhagic hydrocephalus in premature infants.

Science.gov (United States)

Willis, Brian K; Kumar, Cherukuri Ravi; Wylen, Esther L; Nanda, Anil

2005-01-01

The early management of posthemorrhagic hydrocephalus in premature infants is challenging and controversial. These infants need a temporary cerebrospinal fluid (CSF) diversion procedure until they gain adequate weight, and the blood and protein levels in CSF are reasonably low before permanent shunt can be placed. Various options are available with their associated advantages and disadvantages. Ventriculosubgaleal shunts have been recommended as a more physiologic and less invasive means of achieving this goal. We have performed this procedure in 6 premature infants to evaluate their effectiveness and complications. Six consecutive premature infants with posthemorrhagic hydrocephalus underwent placement of ventriculosubgaleal shunts over a 1-year period of time. We reviewed their clinical and imaging progress to assess the ability of the shunt to control hydrocephalus and the complication rates. In all 6 patients, the ventriculosubgaleal shunt controlled the progression of hydrocephalus as assessed by clinical and imaging parameters. A permanent shunt was avoided in 1 patient (16.6%). However, 4 patients developed shunt infections, 1 involving the ventriculosubgaleal shunt itself, and 3 immediately after conversion to ventriculoperitoneal shunt. The total infection rate of the series was 66.6%. All infections were caused by staphylococcus species. There was only a 1% shunt infection rate in our institution for all nonventriculosubgaleal shunts during the same period of time. Placement of ventriculosubgaleal shunts for interim CSF diversion in neonates with posthemorrhagic hydrocephalus is effective as a temporary method of CSF diversion. However, our experience has shown that it is associated with a unacceptably high CSF infection rate. A potential cause for infection is CSF stasis just beneath the extremely thin skin of the premature infants, promoting colonization by skin flora. CSF sampling before conversion to a permanent shunt and replacement of the proximal

OBJECTIVE A recent survey has shown that caregivers of children with shunt-treated hydrocephalus frequently use social media networks for support and information gathering. The objective of this study is to describe and assess social media utilization among users interested in hydrocephalus. METHODS Publicly accessible accounts and videos dedicated to the topic of hydrocephalus were comprehensively searched across 3 social media platforms (Facebook, Twitter, and YouTube) throughout March 2016. Summary statistics were calculated on standard metrics of social media popularity. A categorization framework to describe the purpose of pages, groups, accounts, channels, and videos was developed following the screening of 100 titles. Categorized data were analyzed using nonparametric tests for statistical significance. RESULTS The authors' search identified 30 Facebook pages, 213 Facebook groups, 17 Twitter accounts, and 253 YouTube videos. These platforms were run by patients, caregivers, nonprofit foundations, and patient support groups. Most accounts were from the United States (n = 196), followed by the United Kingdom (n = 31), Canada (n = 17), India (n = 15), and Germany (n = 12). The earliest accounts were created in 2007, and a peak of 65 new accounts were created in 2011. The total number of users in Facebook pages exceeded those in Facebook groups (p social media use in the topic of hydrocephalus. Users interested in hydrocephalus seek privacy for support communications and are attracted to treatment procedure and surgical products videos. These findings provide insight into potential avenues of hydrocephalus outreach, support, or advocacy in social media.

Gross, Paul; Reed, Gavin T; Engelmann, Rachel; Kestle, John R W

2014-02-01

Funding of hydrocephalus research is important to the advancement of the field. The goal of this paper is to describe the funding of hydrocephalus research from the National Institutes of Health (NIH) over a recent 10-year period. The NIH online database RePORT (Research Portfolio Online Reporting Tools) was searched using the key word "hydrocephalus." Studies were sorted by relevance to hydrocephalus. The authors analyzed funding by institute, grant type, and scientific approach over time. Over $54 million was awarded to 59 grantees for 66 unique hydrocephalus proposals from 48 institutions from 2002 to 2011. The largest sources of funding were the National Institute of Neurological Disease and Stroke and the National Institute of Child Health and Human Development. Of the total, $22 million went to clinical trials, $15 million to basic science, and $10 million to joint ventures with small business (Small Business Innovation Research or Small Business Technology Transfer). Annual funding varied from $2.3 to $8.1 million and steadily increased in the second half of the observation period. The number of new grants also went from 15 in the first 5 years to 27 in the second 5 years. A large portion of the funding has been for clinical trials. Funding for shunt-device development grew substantially. Support for training of hydrocephalus investigators has been low. Hydrocephalus research funding is low compared with that for other conditions of similar health care burden. In addition to NIH applications, researchers should pursue other funding sources. Small business collaborations appear to present an opportunity for appropriate projects.

Benign communicating hydrocephalus in children

Kendall, B.; Holland, I.

1981-01-01

A review was performed of the computed tomograms (CTs) of 500 children which had been reported as showing widening of the supratentorial subarachnoid spaces with normal cerebral substance. On the basis of this a radiological diagnosis of cerebral atrophy had been made in all but five, who were said to have mengalencephaly. From these, the children with large or abnormally enlarging heads, but normal or only slightly enlarged ventricles, were selected; there were 40 such cases (8%). The clinical condition either improved or remained stable over a period of 2 years; in the majority the scan abnormality regressed (22.5%) or remained static (67.5%). In three cases there was slight progression of the CT changes before stabilisation, but only one case developed classical communicating hydrocephalus necessitating a shunt procedure. This condition is a generally benign and mild form of communicating hydrocephalus, for which an aetiological factor was apparent in about two-thirds of the cases studied. (orig.)

Aim: To explore nurses' knowledge and understanding of the use of observation on patients who self-harm in a learning disability service in the United Kingdom. Design: and methods: This study adopted a qualitative approach, and utilised interpretative phenomenological analysis as a design and as a tool of analysis. The study was conducted in a secure learning disability service in the United Kingdom. Data were obtained from registered nurses using individual interviews (n = 20 and focus groups (n = 3 x 5 = 15. Data were analysed thematically using the principles of interpretative phenomenological analysis. Results: Three superordinate themes emerged from data analysis: 1 observation: its meaning, 2 observation: does it prevent self-harm? 3 Observation: making it work. Conclusion: Observation is a useful practice in in-patient learning disability services, which can be used to prevent or reduce the incidence of self-harm in these settings. This approach should therefore be an integral part of nurses' daily therapeutic activities in inpatient learning disability services.

Math skills are necessary for success in the childhood educational and future adult work environment. This article reviews the changing terminology for specific learning disabilities (SLD) in math and describes the emerging genetics and neuroimaging studies that relate to individuals with math disability (MD). It is important to maintain a developmental perspective on MD, as presentation changes with age, instruction, and the different models (educational and medical) of identification. Intervention requires a systematic approach to screening and remediation that has evolved with more evidence-based literature. Newer directions in behavioral, educational and novel interventions are described.

The purpose of this study was to document the design, classroom implementation, and effectiveness of interactive online units to enhance science learning over 3 years among students with learning disabilities, English learners, and general education students. Results of a randomised controlled trial with 2,303 middle school students and 71 teachers across 13 schools in two states indicated that online units effectively deepened science knowledge across all three student groups. Comparing all treatment and control students on pretest-to-posttest improvement on standards-based content-specific assessments, there were statistically significant mean differences (17% improvement treatment vs. 6% control; p English learner status, indicating that these two groups performed similarly to their peers; students with learning disabilities had significantly lower assessment scores overall. Teachers and students were moderately satisfied with the units.

Hydrocephalus is a common brain disorder that is treated only with surgery. The basis for surgical treatment rests on the circulation theory. However, clinical and experimental data to substantiate circulation theory have remained inconclusive. In brain tissue and in the ventricles, we see that osmotic gradients drive water diffusion in water-permeable tissue. As the osmolarity of ventricular CSF increases within the cerebral ventricles, water movement into the ventricles increases and causes hydrocephalus. Macromolecular clearance from the ventricles is a mechanism to establish the normal CSF osmolarity, and therefore ventricular volume. Efflux transporters, (p-glycoprotein), are located along the blood brain barrier and play an important role in the clearance of macromolecules (endobiotics and xenobiotics) from the brain to the blood. There is clinical and experimental data to show that macromolecules are cleared out of the brain in normal and hydrocephalic brains. This article summarizes the existing evidence to support the role of efflux transporters in the pathogenesis of hydrocephalus. The location of p-gp along the pathways of macromolecular clearance and the broad substrate specificity of this abundant transporter to a variety of different macromolecules are reviewed. Involvement of p-gp in the transport of amyloid beta in Alzheimer disease and its relation to normal pressure hydrocephalus is reviewed. Finally, individual variability of p-gp expression might explain the variability in the development of hydrocephalus following intraventricular hemorrhage. PMID:25165050

The purpose of this study was to gain an understanding of the career development and learning pathways of Paralympic head coaches who previously competed as Paralympic athletes. Each coach participated in a semistructured interview. A thematic analysis of the data revealed three higher order themes, which were called becoming a coach, learning to coach, and lifelong learning and teaching. Across these themes, participants discussed interactions with other coaches and athletes with a disability, learning from mentors and coaching clinics, as well as limited formal educational opportunities they experienced transitioning from athlete to head coach. The findings revealed that they acquired most of their knowledge from a combination of knowledge gained as athletes and informal sources, including trial and error. They also stressed the need for enhanced recruiting of parasport coaches and parasport coach education opportunities that would enhance programs for athletes with physical disabilities, from grassroots to Paralympic levels.

Pathophysiological study of experimental hydrocephalus with computed tomography (CT) scan

In order to investigate the pathophysiological changes during a development of hydrocephalus, the observations employing computed tomography (CT) scans and monitorings of intracranial epidural pressure (EDP) were performed in a series of kaolin-induced canine hydrocephalus. According to ''volume index'' of ventricles which was calculated from printed-out CT numbers, great individual variations were recognized in the degree of a ventricular enlargement as well as the rate of EDP. They are thought to be due to the difference in types of hydrocephalus, which have been induced by a discrepancy in the site and degree of an obstruction caused by kaolin. Periventricular lucency (PVL) of various degrees were also detected on CT scans of experimental hydrocephalus. It was always marked in the superolateral angle of frontal horn of the lateral ventricles, and differed in degree from severe to mild. PVLs were distinct in the acute stage with high EDP, and gradually became indistinct and had a tendency to disappear thereafter along with decreased EDP. They immediately disappeared after shunting operation. The pathogenesis of PVL was investigated with histological examinations, as well as by using contrast enhancement, Metrizamide ventriculography, the analysis of linear density profiles, and the measurement of regional cerebral blood flow (rCBF). Consequently, PVLs in hydrocephalus are considered to represent an acute edema or a chronic CSF retention in the periventricular white matter caused by increase of water content. In other words, they are regarded as a sign of present or preceding intraventricular hypertension on CT scan, and may become a clinical indication for shunting operation. (author)

The aim of this study was to analyze risk factors for the development of hydrocephalus in newborn infants with germinal matrix (GM) hemorrhage. The study comprised 271 patients admitted to Carlos Haya University Hospital in Malaga with GM hemorrhage. The following data were recorded: gestational age, gender, twin birth, head circumference at birth, weight at birth, and Papile grade. Severe obstetrical (abruption, chorioamnionitis, pregnancy-induced hypertension, tocolytic treatment) and neonatal disorders (respiratory distress syndrome, neonatal infection, coagulation disorder, patent ductus arteriosus, necrotizing enterocolitis) were also recorded. Symptomatic hydrocephalus was diagnosed in the event of a progressive increase in head circumference and ventricular indices requiring shunting. Of the 271 patients, 139 (51%) developed posthemorrhagic ventriculomegaly; 47 patients (17%) developed symptomatic hydrocephalus and needed shunt implantation. We found a significant relationship between the development of symptomatic hydrocephalus and Papile grade, lower gestational age, lower birth weight, twin birth, and neonatal infection. Awareness of risk factors for the development of hydrocephalus in newborn infants with GM hemorrhage should be emphasized in order to enable an early diagnosis of ventriculomegaly and symptomatic hydrocephalus and thus make a correct therapeutic decision.
