not be. It is generally accepted by medical professionals that the manifestation of multigenetic disease during the lifetime of a gene carrier depends on certain environmental factors. This hip disorder can develop and even be exacerbated when certain environmental factors are present, but can also recede without further intervention following elimination of those same factors at an early devel...

PURPOSE To review records of children referred to our hospital for developmental dysplasia of the hip (DDH) and evaluate the effectiveness of hip screening in Hong Kong. METHODS Records of children suspected of DDH and referred to our hospital between 1 January 2005 and 31 March 2010 were reviewed. The diagnosis was based on static and dynamic ultrasonography of the hips and/or radiographic f...

Trapdoor Decisional Diffie-Hellman (TDDH) groups, introduced by Dent and Galbraith (ANTS 2006), are groups where the DDH problem is hard, unless one is in possession of a secret trapdoor which enables solving it efficiently. Despite their intuitively appealing properties, they have found up to now very few cryptographic applications. Moreover, among the two constructions of such groups proposed...

OBJECTIVES To describe the pattern of developmental dysplasia of the hip (DDH) in late presenting Jordanian male patients and identify the risk factors and associated findings. METHODS This is a retrospective study of 1145 male patients who attended the Pediatric Orthopedic Clinic for a DDH check up. This study was carried out in the Orthopedic Section, Special Surgery Department, Faculty of ...

This study aimed to determine whether abnormal apoptosis is present in acetabular cartilage in early developmental dislocations of the hip (DDH), and if so, whether it is correlated with the expression of caspase-3 and Bcl-2. DDH was induced in 24 4-week-old New Zealand white rabbits. Acetabular cartilage specimens from the experimental and control groups were stained with hematoxylin and eosin...

AIM To determine if there was a seasonal variation in adults undergoing total hip arthroplasty for end stage hip disease due to osteoarthritis (OA) or sequelae of developmental dysplasia of the hip (DDH). METHODS The total hip registry from the author's institution for the years 1969 to 2013 was reviewed. The month of birth, age, gender, and ethnicity was recorded. Differences between number ...

PURPOSE OF THE STUDY Aim of the study was to analyze age structure of the patients with developmental dysplasia of the hip (DDH) at the time of the operation and epidemiological determinants: gender distribution, proportion of left or right hip affection, type of delivery and mode of labor presentation. MATERIAL AND METHODS The population of 78 children with DDH was evaluated. Three age group...

Between 1985 and 1998, 12,331 patients were included in the general neonatal ultrasound hip screening programme for developmental dysplasia of the hip (DDH). Patients who needed treatment (604) were compared with a second group of 73 unscreened children treated conservatively and surgically for DDH. The incidence of Graf sonographic hip types IIc to IV varied throughout the observation period. ...

In this paper, we first show a DDH Lemma, which states that a multi-variable version of the decisional Diffie-Hellman problem is hard under the standard DDH assumption, where the group size is not necessarily known. Our proof, based on a self-reducibility technique, has a small reduction complexity. Using DDH Lemma, we extend the FSS pseudorandom generator of Farashahi et al. to a new one. The ...
