Psychiatric symptoms in children with gross motor problems.

Children with psychiatric disorders often demonstrate gross motor problems. This study investigates if the reverse also holds true by assessing psychiatric symptoms present in children with gross motor problems. Emotional, behavioral, and autism spectrum disorders (ASD), as well as psychosocial problems, were assessed in a sample of 40 children with gross motor problems from an elementary school population (aged 7 through 12 years).

Gross motor performance and physical fitness in children with psychiatric disorders.

Aim: Gross motor performance appears to be impaired in children with psychiatric disorders but little is known about which skill domains are affected in each disorder, nor about possible accompanying deficits in physical fitness. The present study has sought to provide information about these issues in children with emotional, behavioural, and pervasive developmental disorders (PDD).

Method: One hundred children receiving psychiatric care (81 males, 19 females, mean age 9y 11mo, SD 1y 8mo) completed both the Test of Gross Motor Development, measuring locomotion and object control, and the Motor Performance test, measuring neuromotor and aerobic fitness.

Participants: Ten people after stroke volunteered for the study and comprised the experimental group.

Effects of exercise programs on falls and mobility in frail and pre-frail older adults: A multicenter randomized controlled trial.

Objectives: To determine the effects of moderate intensity group-exercise programs on falls, functional performance, and disability in older adults; and to investigate the influence of frailty on these effects.

Design: A 20-week, multicenter randomized controlled trial, with 52-week follow-up.

Setting: Fifteen homes for the elderly.

Clinimetric properties of the performance-oriented mobility assessment.

Background And Purpose: The Performance-Oriented Mobility Assessment (POMA) is a widely used instrument that provides an evaluation of balance and gait. It is used clinically to determine the mobility status of older adults or to evaluate changes over time. To support the use of the POMA for these purposes, the clinimetric properties (in particular, responsiveness) were determined.

[Ovarian tumour in a girl with chronic abdominal pain and distension].

A 12-year-old girl presented with chronic abdominal pain and distension that had persisted for 6 and 3 months, respectively. The cause was a Sertoli-Leydig cell tumour originating in the left ovary. The cyst and ovary were resected.

[Optimal breastfeeding to prevent hyperbilirubinaemia in healthy, term newborns].

In a newborn infant, frequent bowel movements diminish the enterohepatic circulation of bilirubin, thereby increasing bilirubin excretion. In breastfed newborn infants, the frequency of latching on and administration of supplementary feeds are associated with serum bilirubin concentrations. Frequent breast feeding (at least 8 times a day) and fewer supplementary feeds will result in increased breast milk intake, less weight loss, and lower bilirubin concentrations.

'Most advanced, yet acceptable': typicality and novelty as joint predictors of aesthetic preference in industrial design.

Typicality and novelty have often been shown to be related to aesthetic preference of human artefacts. Since a typical product is rarely new and, conversely, a novel product will not often be designated as typical, the positive effects of both features seem incompatible. In three studies it was shown that typicality (operationalized as 'goodness of example') and novelty are jointly and equally effective in explaining the aesthetic preference of consumer products, but that they suppress each other's effect.

Coordination disorders in patients with Parkinson's disease: a study of paced rhythmic forearm movements.

Whereas the consequences of Parkinson's disease (PD) for the performance of single-limb movements are well documented (i.e., bradykinesia, akinesia, rigidity, and tremor), fairly little is known about its implications for the coordination between limb movements.

Coordination in prehension. Information-based coupling of reaching and grasping.

Prehension involves the coordination of a reaching and a grasping movement, such that the hand opens and closes in tune with the transport of the hand to the object to be grasped. To investigate this coordination, we focused on the transition from hand opening to hand closing in the grasping component of prehension. Earlier research has suggested that the time taken to close the hand remains constant over varying reaching amplitudes.

Frequency-induced phase transitions in bimanual tapping.

The stability of bimanual performance of the frequency ratios 3:8 and 5:8 was examined from the perspective of the sine circle map and the associated Farey mode-locking hierarchy. By gradually increasing movement frequency, abrupt transitions from the initial frequency ratios to other frequency ratios were induced. In general, transitions occurred to frequency ratios that were near the initial frequency ratio but lower in the Farey ordering, and, hence, of higher stability in the sine circle map.

[A rare cause of hemiparesis: cerebral hydatidosis].

A 6-year-old Turkish boy was brought to the Netherlands by his immigrant father because of hemiparesis. There were no signs of raised intracranial pressure. Cerebral hydatidosis was diagnosed.

Cytomegalovirus directly enhances MHC class I and intercellular adhesion molecule-1 expression on cultured proximal tubular epithelial cells.

Clinically, there is an association between CMV infections and the occurrence of rejection after renal transplantation. Adhesion molecules such as intercellular adhesion molecules (ICAM) and MHC Ags are thought to be important in the induction and amplification of the rejection process. Therefore, we studied ICAM-1 and MHC expression after CMV infection or stimulation with cytokines.

Relative roles of decay-accelerating factor, membrane cofactor protein, and CD59 in the protection of human endothelial cells against complement-mediated lysis.

Human umbilical vein endothelial cells (HUVEC) were found by Western blot analysis to express three membrane-bound C regulatory proteins, decay-accelerating factor (DAF), membrane cofactor protein (MCP) and CD59. DAF was detected on sodium dodecyl sulfate-polyacrylamide gel electrophoresis as a 70-kDa molecule under nonreducing conditions in 2% deoxycholate extracts of HUVEC, MCP as a 63-kDa protein and CD59 as a 20-kDa molecule. Northern blot analysis revealed the presence of two species of mRNA expressed in HUVEC, which hybridized to a cDNA probe specific for DAF, with sizes of about 2.

Esophageal stricture as a complication in Henoch-Schönlein purpura.

We report on a three-year-old boy with Henoch-Schönlein purpura developing an esophageal stenosis during severe clinical course of this disease. There are to date no reports on the development of such a complication. The possible pathogenesis in relation to stricture formation of ileum and ureter in Henoch-Schönlein's purpura is discussed.

The transfer of scanning training effects in visual inattention after stroke: five single-case studies.

The transfer effects of scanning training of right-brain-damaged stroke patients with visual inattention have been studied. Five patients were treated according to a B-C-B-D design. The first B phase lasted for 2, 4, or 6 weeks, whereas the other intervention phases had a fixed duration of 2 weeks.

Acquiring an attacking forehand drive: the effects of static and dynamic environmental conditions.

Two groups of 10 novice subjects each were trained to perform attacking forehand drives in table tennis and land the balls as fast and as accurately as possible onto a target on the opposite side of the net under two different training conditions. Under the static training condition, the balls were to be struck from a constant position, and under the dynamic training condition, balls approached the subjects in a normal way. Both groups were tested under dynamic conditions prior to and after four days of training, during which they received 1,600 practice trials.

[An infant with 5 weeks of fever of unknown origin and a reasonably good clinical condition; leishmaniasis].

In a Dutch infant, aged 10 months, with fever of unknown origin for 5 weeks and a relatively good clinical condition splenomegaly was present. Visceral leishmaniasis was diagnosed. The parasite is found in (sub)tropical regions and had in this case been acquired in Southern Spain.

Atypical characteristics of a group of children with intussusception.

We describe the characteristics of a group of 140 children with intussusception. They differed strikingly from the classical picture of intussusception given in textbooks and in publications concerning large series. We found a low incidence of intussusception especially in infants and young children.
