OBJECTIVE Photodynamic diagnosis (PDD) of superficial bladder cancer decreases recurrence rates. We present oncological results of a randomized, prospective study, comparing transurethral resection (TUR) performed under conventional white light (WL) with PDD. The follow-up period is the longest reported to date. As costs might be reimbursed by prolonged recurrence-free survival in certain patie...

A proventricular dilatation disease (PDD) outbreak provided the opportunity to investigate the transmissibility of avian Bornavirus (ABV) and its linkage to PDD under natural conditions. Upon exposure to a bird with a fatal case of PDD, 10 birds became symptomatic and died. ABV2 RNA was recovered from available tissues. Further screening revealed that 12/46 exposed birds were ABV2(+). Three chi...

Trefoil factor 3 (TFF3), cholinesterase activity (ChE activity) and homocysteine (Hcy) play critical roles in modulating recognition, learning and memory in neurodegenerative diseases, such as Parkinson's disease dementia (PDD) and vascular parkinsonism with dementia (VPD). However, whether they can be used as reliable predictors to evaluate the severity and progression of PDD and VPD remains l...

This paper examines two stochastic methods stemming from polynomial dimensional decomposition (PDD) and polynomial chaos expansion (PCE) for solving random eigenvalue problems commonly encountered in dynamics of mechanical systems. Although the infinite series from PCE and PDD are equivalent, their truncations endow contrasting dimensional structures, creating significant differences between th...

Despite prominent attentional symptoms in Pervasive Developmental Disorders (PDD) the relationship between PDD and Attention Deficit Hyperactivity Disorder (ADHD) has received little direct examination. In addition, outcome studies of children with PDD often focus on language, educational placement, or adaptive skills, but seldom on loss of the PDD diagnosis or change to another clinical syndro...

OBJECTIVES Noninvasive urothelial carcinoma of the bladder (UCB) causes an enormous economic burden to public health systems due to its life-long character and frequent recurrences. While white light (WL) cystoscopy is considered to be the gold standard for transurethral resection of the bladder, photodynamic diagnostic (PDD) has been shown to improve final outcome. Escalating healthcare costs ...

Subjects with PDD excel on certain visuo-spatial tasks, amongst which visual search tasks, and this has been attributed to enhanced perceptual discrimination. However, an alternative explanation is that subjects with PDD show a different, more effective search strategy. The present study aimed to test both hypotheses, by measuring eye movements during visual search tasks in high functioning adu...

BACKGROUND In clients with pervasive developmental disorders (PDD), some authors have noticed the presence of gastrointestinal disorders and behavioural disorders. An augmented prevalence of different histological anomalies has also been reported. The aim of our study is to highlight the prevalence of gastrointestinal disorders in this adult with PDD sample and to demonstrate the importance of ...

Evidence on the association between somatic chronic diseases in ID-adolescents and the full range of pervasive developmental disorder behavior (PDD behavior) is scarce. The aim of the present study is to assess the association between somatic chronic diseases in ID-adolescents and mild PDD behavior. We obtained data on 1044 ID-adolescents, aged 12-18, attending secondary schools in the Netherla...

We evaluated the utility of the Japanese version of the Checklist for Autism in Toddlers for predicting pervasive developmental disorders (PDD) among 2-year-old children in clinical settings. Confirmed diagnosis revealed that the pass rate on four items (social interest, proto-imperative pointing, proto-declarative pointing and joint-attention) was significantly lower in 52 PDD children than in...
