Today Is My Day: Analysis of the Awareness Campaigns’ Impact on Functional Diversity in the Press, on Google, and on Twitter
2021
(1) Every day, people with functional diversity face different kinds of difficulties that pose a barrier to their social inclusion. These difficulties often go unnoticed by most citizens. Social networks are a powerful tool to sensitize the population. With this objective, different organizations such as associations, federations, foundations, and other institutions have promoted campaigns through the celebration of world days for different types of functional diversity. This research aims to monitor and analyze the impact of these social campaigns in Spain, including Asperger’s syndrome, rare diseases, Down syndrome, autism, hearing and visual impairment, cerebral palsy, dyslexia, ADHD, sp…
Hypercalciuria and kidney calcifications in terminal 4q deletion syndrome: further evidence for a putative gene on 4q.
2004
We report a newborn girl with a de novo terminal 4q deletion (q31.3 --> qter) and a characteristic phenotype of minor facial anomalies, cleft palate, congenital heart defect, abnormalities of hands and feet, and postnatal onset of growth deficiency. Laboratory studies showed excessive urinary calcium excretion on standard milk formula and on oral calcium load. Blood measurements of parathyroid hormone, calcitonin, bicarbonate, calcium, phosphorus, magnesium, sodium, chlorine, potassium, and urinary measurements of phosphorus, magnesium, sodium, chlorine, potassium were normal for age. At 2 months of life, ultrasonography showed kidney calcifications. Clinical and laboratory data support the…
Regional hypothermia of the kidney: surface or transarterial perfusion cooling? A functional study.
1980
Hypothermia reduces ischemic damage if prolonged occlusion of the renal artery is required during an in situ kidney operation. Hypothermia may be achieved by external cooling or by transarterial hypothermic perfusion. External cooling may lower intrarenal temperature heterogeneously. Perfusion techniques via intra-arterial catheters introduced percutaneously are associated with minimal technical difficulties. The 95 patients who underwent extensive hypothermic nephrolithotomy had differential 131iodine hippuran clearance studies preoperatively, and 2 weeks and 6 to 46 months postoperatively. Sixty-three kidneys were cooled by transarterial hypothermic perfusion and 39 were cooled with topic…
Dyscalculia: Clinical manifestations, evaluation and diagnosis. Current Perspectives of educational intervention
2019
Learning difficulties and learning disorders are very frequent in schools nowadays, and they have been increasing in the field of mathematics. Such difficulties tend to be associated with other disorders such as dyslexia or Attention Deficit Hyperactivity Disorder (ADHD). The present article aims at deepening our understanding, definition and detection of dyscalculia, along with reviewing current educational treatments. Since 1990, concerns about learning difficulties in the classroom have been made explicit in policies such as the Spanish Law on the General Ordering of the Education System (LOGSE). Likewise, the indicators, symptoms, and prevalence of dyscalculia have been gathered since t…
Dyscalculia – one of the Types of Learning Disabilities
2015
The article is devoted to a theoretical justification of dyscalculia showing a link between characteristics of brain functions and expressions of learning disorders. Although dyscalculia and dyslexia are linked problems, the cognitive profile is different. Significant understanding of dyscalculia deals with origin and manifestations of it that affect learning in school and future quality of life. Development of neuroscience and brain studies performing magnetic resonance imaging (MRI), allow accurate descriptions of problem and in addition to search for ways to reduce the negative effects of dyscalculia.
Kidney Stones in Primary Hyperoxaluria: New Lessons Learnt
2013
To investigate potential differences in stone composition with regard to the type of Primary Hyperoxaluria (PH), and in relation to the patient’s medical therapy (treatment naïve patients versus those on preventive medication) we examined twelve kidney stones from ten PH I and six stones from four PH III patients. Unfortunately, no PH II stones were available for analysis. The study on this set of stones indicates a more diverse composition of PH stones than previously reported and a potential dynamic response of morphology and composition of calculi to treatment with crystallization inhibitors (citrate, magnesium) in PH I. Stones formed by PH I patients under treatment are more compact and…
Associations Between Childhood Learning Disabilities and Adult-Age Mental Health Problems, Lack of Education, and Unemployment.
2019
We studied the impact of diverse subtypes of learning disabilities (LD) on adult-age mental health, education, and employment by comparing the LD group ( n = 430) with a matched control group without a known history of LD ( n = 2,149). The clinical archived data were merged with lifelong register data on sickness allowances/disability pensions granted on the basis of psychiatric illnesses, reimbursements for psychoactive medication, having a degree after compulsory education, and having received unemployment allowances. Differences emerged between the LD and control groups in all outcomes, suggesting that a higher proportion of individuals with LD had mental health problems compared to the…
Early Cognitive Precursors of Children's Mathematics Learning Disability and Persistent Low Achievement: A 5-Year Longitudinal Study.
2018
Mathematical difficulties have been distinguished as mathematics learning disability (MLD) and persistent low achievement (LA). Based on 1,880 Finnish children who were followed from kindergarten (age 6) to fourth grade, this study examined the early risk factors for MLD and LA. Distinct groups of MLD (6.0% of the sample) and LA (25.7%) children were identified on the basis of their mathematics performance between first and fourth grades with latent class growth modeling. Impairment in the same set of cognitive skills, including language, spatial, and counting skills, was found to underlie MLD and LA. The finding highlights the importance of monitoring mathematical development across the ea…
Local Shock-Wave Lithotripsy of Distal Ureteral Calculi
1988
Abstract Since the initiation of the clinical trial utilizing a second-generation lithotripor (Lithostar, Siemens, Erlangen, FRG), 96 patients with distal ureteral calculi (i.e. calculi below the pelvic brim) underwent local shock-wave lithotripsy. Routine treatment was conducted under intravenous sedation and light analgesia only. Complete stone disintegration was achieved in 84 patients (87.5%), 11 requiring two sessions and 1 patient, three. In 7 patients ureteroscopy became necessary after unsuccessful local shock-wave treatment. In 2 of these patients a 9-french flexible ureteroscope and the Storz Q-switched neodymium-YAG laser was used for stone disintegration. In 3 cases loop extract…
The Role of Learning Difficulties in Adolescents’ Academic Emotions and Academic Achievement
2019
The present study examines associations between learning difficulties (LD), academic emotions, and academic achievement among 845 Grade 6 adolescents (455 girls, 390 boys). Reading difficulties (RD) and math difficulties (MD) were identified based on tested reading and math skills in the fall semester of Grade 6. At this time, the students also rated their hope, enjoyment, and anxiety regarding literacy and math. Information on students' achievement in literacy and math, as well as their overall academic achievement, was gathered using questionnaires in both the fall and spring semesters of Grade 6. The results show, first, that students with RD had lower hope and higher anxiety toward read…
