The majority of work on the double-deficit hypothesis (DDH) of dyslexia has been done at the letter and word levels of reading. Key research questions addressed in this study are (a) do readers with different subtypes of dyslexia display differences in fluency at particular reading levels (e.g., letter, word, and connected text)? and (b) do children with dyslexia identified by either low-achiev...

Comprehensive gait analysis of patients with Crowe type II and III developmental dysplasia of the hip (DDH) after successful total hip arthroplasty (THA) is lacking in the literature. This study evaluated gait function in joint kinematics after unilateral and bilateral THA in patients with DDH. In addition, the effect of high cup position on gait function was investigated. A total of 16 unilate...

congenital hip dysplasia congenital hip dislocation developmental dysplasia of the hip ultrasonography, methods. The purpose of this study is to establish the diagnostic value of combine using static (Graf) and dynamic (Harcke) ultrasonography methods. Both static and dynamic methods were used only in Graf’s Type 1 and Graf’s Type 2a patients. Groups were classified as normal findings (Group A)...

The pragmatic species concept for Bacteria and Archaea is ultimately based on DNA-DNA hybridization (DDH). While enabling the taxonomist, in principle, to obtain an estimate of the overall similarity between the genomes of two strains, this technique is tedious and error-prone and cannot be used to incrementally build up a comparative database. Recent technological progress in the area of genom...

Femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH) are fundamentally and structurally different hip abnormalities yet their clinical presentation can often be very similar. We asked whether adult patients surgically treated for DDH when compared with FAI patients achieve (i) better outcome as reflected by the WOMAC Osteoarthritis Index, (ii) higher physical activity...

High-level ab initio calculations have been used to study the mechanism for the inactivation of diol dehydratase (DDH) by glycolaldehyde or 2-chloroacetaldehyde. As in the case of the catalytic substrates of DDH, e.g., ethane-1,2-diol, the 5'-deoxyadenosyl radical (Ado*) is able to abstract a hydrogen atom from both substrate analogues in the initial step on the reaction pathway, as evidenced b...

OBJECTIVE To evaluate the knowledge on developmental dysplasia of the hip (DDH) by professionals involved in its diagnosis. METHODS This is a cross-sectional study using questionnaires to assess the knowledge about DDH. Orthopedic surgeons and pediatricians, residents and medical students from a tertiary teaching hospital were included in the study. RESULTS We evaluated 142 medical students...

Developmental dysplasia of the hip (DDH) or congenital hip dysplasia (CDH) is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DD...

PURPOSE AND METHOD The Invader assay was developed to identify 23 mycobacterial species using probes derived from the species-specific region of the 16S rRNA gene and the 16S-23S rRNA internal transcribed spacer 1 (ITS-1) region, with minor modifications of our previous study. In the present study, we compared the identification capability between the Invader assay and DNA-DNA hybridization (DD...

Developmental dysplasia of the hip (DDH) is a wide-spectrum disease with a multifactorial etiology and, despite its prevalence, no definitive etiology has yet been established. The aim of this study was to investigate new risk factors for DDH by evaluating newly defined potential risk factors. A total of 71 infants were separated into 2 groups:Group I, 28 female first-born infants diagnosed wit...
