Fifteen of 152 pediatric patients with spinal cord insults (10%) developed heterotopic ossification (HO) at 19 locations. The average age of the patient was eight and one-half years. The spinal cord levels were 13 thoracic and two cervical. The average time to detection of the HO from spinal insult was six and one-half years. The hip was involved in 15 of(More)
Children with respirator-dependent quadriplegia because of C-2 spinal cord injuries are now surviving the acute stages of their injury. The major cause of mortality and morbidity in the chronic stage is due to respiratory complications. Surveillance, 24 h/d, is the best way to prevent accidental disconnection of respirator equipment from the patient and its(More)
A compact testbed for real-time UWB performance evaluation in terms of un-coded bit-error rate is presented. Both the transmitter and the receiver are realized in form of a small PCB. This testbed represents a very versatile tool for the evaluation of IR-UWB as physical layer for various wireless technologies. It operates in the frequency range from 3.1-5.0(More)
The electromagnetic environment in a hospital is characterized by means of a measurement campaign. This serves as a basis for the evaluation of best-suited future technologies to be used for wireless patient monitoring, where highest quality of service is required for sensors recording vital data. Results show that the UWB band features equal dynamic ranges(More)
Sixty-four quadriplegic children and adolescents were evaluated to determine the benefits of bracing and spinal fusion on the progression and extent of their spinal curves. All those injured before 14 years of age developed a spinal deformity. Bracing in a body jacket assists in maintaining sitting balance and posture and also helps to minimize(More)
A compact testbed for real-time Ultra-Wideband (UWB) wireless system performance evaluation in terms of un-coded bit-error rate is presented. Both the transmitter and the receiver are realized in form of a small PCB. The system operates in the frequency range from 3.1--5.0 GHz with a maximum data rate of 10 MBit/s. By means of two examples this poster(More)
The usual treatment of venous ulcers may be associated with statins intake. Antibiotics have only marginal utility in acute bronchitis. The prescription of paracetamol seems to have no benefit in the treatment of acute lower back pain. The absence of antithrombotic prophylaxis for distal fractures of the lower limbs seems to be safe for patients' health.(More)
Benzodiazepines are associated with the risk of developing Alzheimer's disease. Systematic dosage and vitamin D substitution have no place in times of immediate post-menopause. Topical placebos challenge analgesics in the treatment of knee osteoarthritis. Palliative chemotherapy does not improve life-quality at the end of life. Restrictive transfusion(More)
