OBJECTIVE The aim of this study was to detect the incidence of estrogen receptors in human hip joint capsule and ligamentum teres. METHODS The study included biopsies of the ligamentum capitis femoris (LCF) and hip joint capsule from 15 patients undergoing hip surgery for developmental dysplasia of the hip (DDH) and from the control hips of 15 cases of intrauterine fetal death. Mean age was 1...

We have analysed the patterns of management of developmental dysplasia of the hip (DDH) in Coventry over a period of 20 years during which three different screening policies were used. From 1976 to the end of 1985 we relied on clinical examination alone. The mean surgical cost for the treatment of DDH during this period was Pound Sterling 5110 per 1000 live births. This was reduced to Pound Ste...

BACKGROUND Developmental dysplasia of the hip (DDH) is a common cause of secondary osteoarthritis (OA) in younger patients, and when end-stage OA develops, a THA can provide a solution. Different options have been developed to reconstruct these defects, one of which is impaction bone grafting combined with a cemented cup. To determine the true value of a specific technique, it is important to e...

We give the first simple and efficient construction of verifiable random functions (VRFs). VRFs, introduced by Micali et al. [MRV99], combine the properties of regular pseudorandom functions (PRFs) [GGM86] (i.e., indistinguishability from a random function) and digital signatures [GMR88] (i.e., one can provide an unforgeable proof that the VRF value is correctly computed). The efficiency of our...

OBJECTIVE To review the effectiveness of, and make practice recommendations for, serial clinical examination and ultrasound screening for developmental dysplasia of the hip (DDH) in newborns. The effectiveness of selective screening of high-risk infants with hip and pelvic radiographs and treatment with abduction therapy are also examined. OPTIONS Screening: serial clinical examination, ultra...

Charged particle beam manipulation requires magnetic dipoles for steering and quadrupoles for focusing. Conventional magnets are currently used leading to very large and heavy systems. Miniaturization of the optic magnets would enable the development of more affordable systems and potentially portable devices. The Advanced Magnet Lab, Inc. has developed a revolutionary magnet topology and packa...

PURPOSE To evaluate the use of the popliteal angle as an indicator for successful closed reduction of developmental dysplasia of the hip (DDH) in children with delayed presentation. METHODS 29 patients aged 6 to 18 months underwent successful closed reduction for unilateral DDH under general anaesthesia. Using a graduated goniometer, the popliteal angle was measured with the hip abducted with...

The Diabetes Self-Help of the state North Rhine-Westfalia (NRW) exists since 1975 as an independent association. Till 2012 it was member in the German Diabetes Federation called Deutscher Diabetiker Bund (DDB). On 8 June 2012 in Berlin there was founded a new patient organisation called Deutsche Diabetes-Hilfe – Menschen mit Diabetes (German Diabetes Help – People with Diabetes) with the abbrev...

BACKGROUND Dorothea Dix State Psychiatric Hospital (DDH) was cited by regulatory agencies in 1999-2001 for serious deficiencies in providing medical care to psychiatric patients. This resulted in a change in the discipline responsible for providing medical care. We report here how clinical staff and regulatory agencies evaluated the change. In addition, we sought to determine how medical care i...

BACKGROUND Sciatic nerve injury is a disastrous adverse complication of surgery and can cause debilitating pain, functional impairment and poor quality of life. Patients with developmental dysplasia of the hip (DDH) have a high incidence of sciatic nerve injury after total hip arthroplasty (THA). A better understanding of the course of the sciatic nerve in patients with DDH may help minimise th...
