background: developmental dysplasia of hip (ddh) is a common childhood disorder, and ultrasonography examination is routinely used for screening purposes. in this study, we aimed to evaluate a modified combined static and dynamic   ultrasound technique for the detection of ddh and to compare with the results of static and dynamic ultrasound techniques.       methods: in this cross-sectional stu...

Although developmental dysplasia of the hip (DDH) is a relatively common disorder, its aetiology remains elusive. The authors undertook a systematic review to determine whether there is an association between DDH and vaginal or caesarean delivery for singleton breech infants. The review focussed on cohort studies which provided risk estimates for DDH in breech-presenting infants, as a function ...

BACKGROUND Mild developmental dysplasia of hip (DDH) causes high morbidity of osteoarthritis (OA) on adult. It is thought that change of collagen and proteoglycans in cartilage may be the direct reasons for osteoarthritis. OBJECTIVE To detect the changes of the expressions of type II collagen of acetabular cartilage in early DDH and to investigate the relevance between type II collagen and th...

The oxygen-free alkane direct dehydrogenation (DDH) is a greener, safer, and more selective alternative to oxygen co-fed conditions produce olefins. Carbon-based catalysts have significantly boosted this branch of catalysis by providing cheaper, robust, durable, environmentally friendly single-phase materials as valuable substitutes variety alkaline- or alkaline earth-promoted transition metal ...

Abstract Aim Early detection of DDH is associated with the increased success non-surgical treatment. Therefore, Cardiff and Vale Health Board (CAVUHB) implemented an extended screening program for Developmental dysplasia Hip (DDH) to improve neonatal public health within population. Method A 4-year prospective case-control study all patients born between 01/01/2016-31/12/2019 (n = 21843) who un...

Lossy Trapdoor Functions (LTFs) were introduced by Peikert and Waters in STOC ’08 and since then have found many applications and have proven to be an extremely useful and versatile cryptographic primitive. Lossy trapdoor functions were used to build the first injective trapdoor functions based on DDH, the first IND-CCA cryptosystems based on lattice assumptions, and they are known to imply det...

From the birth of blockchain technology, multisignatures attract much attention as a tool for handling transactions. Concerning application to blockchain, with public-key aggregation, which can compress public keys signers single key, is preferable standard multisignature because and signature used in transaction are stored verify later. Several schemes key aggregation proposed, however, there ...

Aim To establish the positive predictive value (PPV) of clinical hip examinations performed by referrers in Danish screening programme for Developmental Dysplasia Hip (DDH) utilising three definitions true DDH diagnosis. Methods We retrospectively identified 290 children (169 female) referred during a 4-year period to orthopaedic outpatient clinic at our institution with examination. Positive w...
