Echocardiographic reference ranges for normal left ventricular 2D strain: results from the EACVI NORRE study
2017
International audience; Aims - To obtain the normal ranges for 2D echocardiographic (2DE) measurements of left ventricular (LV) strain from a large group of healthy volunteers accounting for age and gender. Methods and results - A total of 549 (mean age: 45.6 ± 13.3 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. 2DE data sets have been analysed with a vendor-independent software package allowing homogeneous measurements irrespective of the echocardiographic equipment used to acquire the data sets. The lowest expected values of LV strains and twist calculated as ± 1.96 standard deviations from the mean…
The role of peer groups in male and female adolescents' task values and physical activity.
2011
The purpose of this longitudinal study was to examine the role of peer groups and sex in adolescents' task values and physical activity. The participants were 330 Finnish Grade 6 students (173 girls, 157 boys), who responded to questionnaires that assessed physical education task values during the spring semester (Time 1). Students' physical activity was assessed one year later (Time 2). The results indicated that adolescent peer groups were moderately homogeneous in terms of task values toward physical education and physical activity. Girls' peer groups were more homogeneous than those of boys in regards to utility and attainment values. Furthermore, the results for both girls and boys sh…
Echocardiographic reference ranges for normal cardiac chamber size: Results from the NORRE study
2014
AimsAvailability of normative reference values for cardiac chamber quantitation is a prerequisite for accurate clinical application of echocardiography. In this study, we report normal reference ranges for cardiac chambers size obtained in a large group of healthy volunteers accounting for gender and age. Echocardiographic data were acquired using state-of-the-art cardiac ultrasound equipment following chamber quantitation protocols approved by the European Association of Cardiovascular Imaging.MethodsA total of 734 (mean age: 45.8 ± 13.3 years) healthy volunteers (320 men and 414 women) were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORR…
Glucose/galactose malabsorption caused by a defect in the Na+/glucose cotransporter.
1991
Glucose/galactose malabsorption (GGM) is an autosomal recessive disease manifesting within the first weeks of life and characterized by a selective failure to absorb dietary glucose and galactose from the intestine. The consequent severe diarrhoea and dehydration are usually fatal unless these sugars are eliminated from the diet. Intestinal biopsies of GGM patients have revealed a specific defect in Na(+)-dependent absorption of glucose in the brush border. Normal glucose absorption is mediated by the Na+/glucose cotransporter in the brush border membrane of the intestinal epithelium. Cellular influx is driven by the transmembrane Na+ electrochemical potential gradient; thereafter the sugar…
Benton visual form discrimination test in healthy children: normative data and qualitative analysis
2018
The attention evaluation may be considered a crucial phase in neuropsychological assessment. It must take into account the systemic nature of the attentional functions and must use different reliable tests in relation to the neurological and attentional problems to be addressed. The aim of the study was to offer the clinician an effective tool for attention assessment and provide the normative data and performance analysis on the Benton Visual Form Discrimination Test on an Italian sample (number 323) of healthy school children, from ages 5 to 11. Performance on Visual Form Discrimination Test (VFDT) significantly increased with growing age. Performances were significantly different when th…
Thermal Thresholds Predict Painfulness of Diabetic Neuropathies
2004
OBJECTIVE—Pathophysiology explaining pain in diabetic neuropathy (DN) is still unknown. RESEARCH DESIGN AND METHODS—Thirty patients with peripheral DN (17 men and 13 women; mean age 52.4 ± 2.5 years) were investigated. Fifteen patients had neuropathic pain, and 15 patients were free of pain. Patients were followed over 2 years and examined at the beginning and thereafter every 6 months. Clinical severity and painfulness of the DN were assessed by the neuropathy impairment score and visual analog scales (VASs). Cold and warm perception thresholds as well as heat pain thresholds were obtained for evaluation of Aδ- and C-fibers. Nerve conduction velocities (NCVs) and vibratory thresholds were …
Influence of age and gender on reference values for common pediatric sleep questionnaires: Results from a community-based study.
2017
Abstract Objectives Sleep problems are often assessed using questionnaires, but it is unclear whether the responses given are influenced by age and gender. We addressed this question in several widely used pediatric sleep questionnaires and provide age-dependent percentile curves. Methods Data of a community-based study in schoolchildren were reanalyzed (N = 163, 50% males, age 6–17 years). Children and their parents completed the Sleep-Related Breathing Disorder Scale (SRBDS) of the Pediatric Sleep Questionnaire, the Sleep Disturbance Scale for Children (SDSC), the Sleep Self Report (SSR) of the Children's Sleep Habits Questionnaire in a long and short version, the Epworth Sleepiness Scale…
Urachal remnants in asymptomatic children: sonographic morphology.
1991
The sonographic morphology of urachal remnants is not well known and findings tend to be misinterpreted. We present urachal remnants in 16 asymptomatic children (1 week-16 years). In the prevesical part two different types of urachal remnants were found: the tubular type with a small outer muscle wall and the fusiform type with a muscle wall thickness up to 12 mm. Further subvariants are presented. Differential diagnosis of the fusiform type includes urachal cyst and tumorous muscle thickening.
Vascular damage and lack of angiogenesis in systemic sclerosis skin
2003
The aim of this study was to analyse microvascular damage and compensatory angiogenesis in skin from patients with systemic sclerosis (SSc) compared with systemic lupus erythematosus (SLE), Raynaud's phenomenon (RP) and healthy controls. Immunohistochemistry was used for skin biopsies (9 SSc, 10 SLE, 9 RP and 12 healthy controls) using von Willebrand factor and beta3 integrin subunit specific antibodies, TechMate immunostaining robot and biotin-streptavidin protocol. In the early stages of SSc, vWF was found in the perivascular space and interstitial matrix in papillary but not in the reticular dermis, in particular around small oedematous blood vessels infiltrated by mononuclear cells. The…
Intramural neovascularization and haemorrhages are major long‐term effects of intravascularγ‐radiation after stenting
2003
Structural changes that might influence the structural integrity of the vessel in response to intravascular brachytherapy (IVB) and stenting were examined, focus being on the importance of neovascularization in rabbit stented arteries. Stents were implanted in the infrarenal aortas of rabbits, immediately followed by gamma IVB or a sham radiation procedure, and the arteries harvested at 6 months. Labelling for von Willebrand factor showed an increase in adventitial and medial neovascularization in irradiated versus control arteries group (5.04+/-0.89 versus 1.51+/-0.23 mm(-2), respectively; p=0.004). Moreover, intramedial haemorrhages (free hemosiderin deposition) and inflammation (macropha…
