Time processing in children with Tourette's syndrome.
2010
Background: Tourette syndrome (TS) is characterized by dysfunctional connectivity between prefrontal cortex and sub-cortical structures, and altered meso-cortical and/or meso-striatal dopamine release. Since time processing is also regulated by fronto-striatal circuits and modulated by dopaminergic transmission, we hypothesized that time processing is abnormal in TS. Methods: We compared time processing abilities between nine children with TS-only (i.e. without major psychiatric comorbidities) and 10 age-matched healthy children, employing a time reproduction task in which subjects actively reproduce different temporal intervals, and a time comparison task in which subjects judge whether a …
Long-Term Follow-Up of Children with Surgically Treated Vesicorenal Reflux: Renal Growth
1991
Renal growth after successful surgical correction of vesicoureterorenal reflux (VUR) in childhood was observed in 137 female and 22 male patients over a mean follow-up period of 10.5 years. The renal parenchymal area was determined using a compensatory planimeter. For each measured value, the standard deviation score (SDS) was calculated by comparison with a normal population. On average, renal growth after reflux operation nearly paralleled the expected normal growth rate. Scarred kidneys had a worse growth prognosis than refluxing renal units (RU) without renal damage, growth retardation being correlated with the degree of pyelonephritic changes. The diminished growth rate of scarred kidn…
Genetic and environmental influences on pubertal timing assessed by height growth
2008
Secular trends towards earlier puberty, possibly caused by new environmental triggers, provide a basis for periodic evaluation of the influence and interaction of genetic and environmental effects on pubertal timing. In such studies, a practical marker that reflects timing of puberty in both genders needs to be used. We investigated genetic and environmental influences on pubertal timing by using change in the relative height between early and late adolescence (HD:SDS, height difference in standard deviations) as a new marker of pubertal timing. HD:SDS correlated well with age at peak height velocity in a population of men and women with longitudinal growth data. In 2,309 twin girls and 1,8…
Multicenter prospective study on the use and outcome of rehabilitation after total laryngectomy in Germany
2018
Background The purpose of this study was to assess the use and outcome of rehabilitation after total laryngectomy in Germany. Methods We enrolled patients who were scheduled for total laryngectomy, approached them again after surgery, after 3 months and 1 year. Patients completed questionnaires and were interviewed. Results Of 309 participants, 14% had not received any rehabilitation. Reasons for nonuse were primarily ongoing treatment and poor health. Users of rehabilitation had 4 times the odds of attaining any ability to speak compared to nonusers (odds ratio 3.8, P = .02). The main aim of rehabilitation from the perspective of the users was speech rehabilitation, mentioned by 71% before…
Echocardiographic reference ranges for normal non-invasive myocardial work indices: results from the EACVI NORRE study
2019
International audience; Aims - To obtain the normal ranges for 2D echocardiographic (2DE) indices of myocardial work (MW) from a large group of healthy volunteers over a wide range of ages and gender. Methods and results - A total of 226 (85 men, mean age: 45 ± 13 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. Global work index (GWI), global constructive work (GCW), global work waste (GWW), and global work efficiency (GWE) were estimated from left ventricle (LV) pressure-strain loops. Peak LV systolic pressure was non-invasively derived from brachial artery cuff pressure. The lowest values of MW indic…
Sulpiride has an antiaggressive effect in mice without markedly depressing motor activity
1991
The atypical neuroleptic, sulpiride is a selective D2 antagonist, having a preferential action on mesolimbic regions. The effects of acute and chronic treatment with sulpiride on aggressive behaviour in male mice were studied using an ethologically based analysis. It was hypothesized that sulpiride would diminish "threat" and "attack" but would not produce marked "immobility", because of the mesolimbic effect referred to above. Isolated albino male mice (experimental animals) were confronted by "standard opponents". Acutely-treated experimental animals received an intraperitoneal injection of sulpiride (20, 50 or 100 mg/kg) 30 min before testing. Chronically-treated animals received sulpiri…
Stiffness degree of ankle range of motion in diabetic patients with atypical amputation
2020
SUMMARY In diabetics, foot deformities are risk factors that increase the risk of amputation as a result of developing ulcers. However, knowledge of the influence of plantar stiffness is still limited. The main objective was to describe connections between the degree of stiffness of the ankle, atypical amputation, and the Foot Posture Index (FPI). METHODS 62 diabetic patients, 58 with type 2 and 4 with type 1 (average age 63.35 years) were included. Records of foot deformities were included; A range of motion test of the ankle joint was used to determine the degree of stiffness. An exploratory analysis of the association of foot position and the degree of rigidity was performed. RESULTS The…
Diagnostic use of fructosamine assay in the control of type II diabetes mellitus.
1988
In an attempt to evaluate the usefulness of fructosamine assay in monitoring type II diabetes, 142 diabetic patients were investigated. Fructosamine values were found to be higher in patients on insulin treatment than on oral hypoglycemic agents. In order to evaluate the metabolic control by using the correlated variations of F, Gm and HbAlc, the patients were subdivided into many control classes: mean values of fructosamine were higher in poorly controlled patients. Fructosamine however correlated better with glycemia in patients with recent variations in metabolic state than HbAlc. It was concluded that fructosamine is a good index for short-term metabolic control, and if used in an integ…
Atrial natriuretic peptide and CD34 overexpression in human idiopathic dilated cardiomyopathies.
2007
Idiopathic dilated cardiomyopathy (IDCM) is a primary myocardial disease of unknown cause characterized by ventricular chamber enlargement with impaired contractile function. In familial forms of IDCM, mutations of genes coding for cytoskeletal proteins related to force transmission, such as dystrophin, cardiac actin, desmin, and delta-sarcoglycan, have been identified. Here, we report the data of a retrospective investigation carried out to evaluate the expression of atrial natriuretic peptide (ANP), CD34, troponin T and nestin in the myocardium of patients affected with IDCM. Formalin-fixed and paraffin-embedded consecutive tissue sections from the ventricular wall of 10 human normal hear…
Mutations of mitochondrial DNA and human death.
1990
In the skeletal muscle of patients with mitochondrial myopathies (Kearns-Sayre syndrome and chronic progressive external ophthalmoplegia) and in the heart and skeletal muscle of healthy persons cells lacking cytochrome c oxidase are found. The respiratory-defective cells have the following features in common: onset of the defect at juvenile or adult age; progressive character of the defect with increasing age; and focal pattern of respiratory-deficient cells (fibers). A statistic mutation of mtDNA in affected cells is suggested to cause the defect of mitochondrial function. It is postulated that the continuous accumulation of respiratory-deficient cells, mainly in the human heart with incre…
