Filter by:Etomidate is an unique drug used for induction of general anesthesia and sedation. Adrenal cortical inhibition by etomidate has received much attention. However wether the circadian rhythm and pulse secretion pattern of cortisol in children are the same as that in adults is not known. Moreover, the effect of etomidate on circadian rhythm changes and clinical outcomes has never been carefully studied in children undergoing surgery. Our hypothesis is that etomidate can relieve the changes of circadian rhythm of salivary cortisol in children for 24-48 hours，and this does not make clinical outcomes worse postoperatively.
The purpose of this study is to determine whether telemedicine video calls for follow-up visits between patients and their orthopaedic trauma surgeons has an impact on patient satisfaction, quality of life, and treatment adherence. This study will also assess the feasibility of telemedicine as a medium for follow-up visits.
BACKGROUND: The World Health Organization Fracture Risk Assessment Tool (WHO FRAX®) Taiwanese calculator is freely available on line to help osteoporosis management. However, its clinical utility for improving osteoporosis awareness and patient acceptance has not been validated in Taiwanese population. OBJECTIVES: This 11-month FRAX® based screening and referral program enrolling older adults participating in the geriatric health examinations (GHEs) at the National Taiwan University Hospital (NTUH) aiming at determine the patient acceptance of the tool and the program and to improve patient awareness in osteoporosis. The second aim is to look for the recommendations from the participating physicians to improve the FRAX® -based osteoporosis management model. METHODS: The NTUH GHE program is a two stage process to serve 3,000 older adults collecting annually from Mar. to Dec. Subjects will be enrolled to the current study at the stage 1 GHE visits after informed consent. Baseline questionnaires including the FRAX® tools will be distributed and expected to be returned at the stage 2 visits. Research assistants will calculate the 10-year predicted fracture risks for the participants during the waiting periods and present the numbers to the GHE physicians. High risks individuals will be referred to general geriatric clinic for further managements. All participants will be provided with osteoporosis and fracture educational material. Patient acceptance and awareness will be assessed. The study is to be started from Feb., to Oct., 2013 to enroll roughly 1,800 older adults assuming refusal rate about 40%. Qualitative interviews will be used to obtain recommendations from study geriatricians in Jul., 2013 to optimize the FRAX® based screening and management model.
Background: The Taiwanese FRAX® (Fracture Risk Assessment Tool) calculator is available online for clinical use. Our Taiwanese Osteoporosis Clinical Treatment Guidelines suggests using the American high risk cut-points for considering treatment but also suggests deriving domestic cut-points from cost-effective approach. Establishing cost-effective domestic cut-points for policy suggestions coupled with mobile devices with wireless access would potentially increase the usage of FRAX® tool. Objectives: 1) Using literature review to establish cost-effectiveness FRAX® cut-points. 2) To assess the effectiveness of mobile devices assisted FRAX® tool based osteoporosis diagnostic and management model. 3) To provide FRAX® based reimbursement policy suggestions. Methods: 1) Investigators will use FRAX®, cost-effectiveness and other key words to search Pubmed and international osteoporosis guidelines to better understand the clinical applications of FRAX® in other countries. Investigators will also search epidemiological data for osteoporosis, facture, quality of life and cost to establish domestic cost-effeteness, and translational approach FRAX® cut-points. 2) Three targeting populations from National Taiwan University Hospital (NTUH) are selected for prospective study (Group A: geriatric health exam clinics with American cut-points, group B: orthopedic clinics with translational approach cut-points and group C: endocrine clinics with cost-effectiveness cut-points,). A mobile device with app application coupled with the FRAX® tool is used by a trained research assistant during clinic waiting periods to screen and enroll high risk (75 from each clinic) adults with informed consents. Participants are referred to geriatric clinics for systemic osteoporosis diagnoses and managements. Percentage of participants that meet the current NHI medication reimbursement regulation and percentage of self-pay medications are calculated. Analysis is stratified by age and gender. 3) The impacts of 3 different cut-points on increment NHI reimbursement are estimated. An osteoporosis expert group meeting is to be held for FRAX® based osteoporosis medication reimbursement modifications to the NHI and the Department of Health. Expected Outcomes: 1) To establish the mobile device assisted FRAX® based osteoporosis screening and management model. 2) Base on the study results and expert consensus, investigators will provide policy suggestions of FRAX® based reimbursement modifications.
The primary purpose of this study is to evaluate the clinical performance of the Arcos Revision Stem system, determine the stability of the implants, and evaluate any relationship between Paprosky bone defect level and the success of the Arcos Stem.
Children who suffer fractures to the growth plates (physes) of their bones are at risk for premature growth arrest which can lead to long term complications. There is currently no technique to predict who is at risk of growth arrest following a physeal injury. The investigators aim to determine if diffusion MRI (an imaging method to analyze tissue properties) can effectively pick up differences between a healthy growth plate and an injured one. This would allow orthopaedics surgeons to predict which injuries are at a higher risk of growth arrest, so earlier interventions can be done in the orthopaedic clinic.
Boys suffer a disproportionately large number of fractures compared to girls (55-60%). This study aims to determine why this is the case by identifying risk factors for wrist fractures. The increase in fracture during childhood and adolescence may be associated with 1) risk-taking behaviour in boys, 2) obesity trends in boys during childhood and adolescence, and/or 3) impaired acquisition of bone strength during childhood and adolescence. Importantly from a knowledge translation perspective, modifiable factors such as behaviour, dietary habits or physical activity in boys may predict fracture. The investigators will measure 400 children (100 girls and 100 boys who have sustained a fracture; 100 same age and sex friends) across 4 years of growth. This study will assess risk behaviours, diet, physical activity, motor proficiency (i.e., balance and coordination), fat and muscle mass and bone strength to determine if there are, 1) differences in whether all or some of these factors predict fractures in boys compared with girls and, 2) whether these factors track forward similarly in boys compared with girls as children advance through the growth spurt.
Humeral shaft fractures represent 1-3% of all fractures and 20% of the humeral fractures. These fractures have historically been treated mainly conservatively with good results. Recent development in fracture treatment and findings that certain fracture types are more prone to non-union and bracing-related functional problems of adjacent joints are somewhat common have caused increasing interest in treating these fractures surgically. Return to activities is also considered to be quicker among surgically treated patients. The purpose of this study is to evaluate effectiveness and cost-effectiveness of surgical treatment of humeral shaft fractures. Patients with an unilateral humeral shaft fracture who are willing to participate in the study after informed consent are randomly assigned to two different treatment methods: 1. Surgical treatment with an open reduction and internal fixation with a 4,5mm locking plate. 2. Conservative treatment with functional bracing The randomization is done using blocked randomization (block sizes are not known by the enrolling or assigning physician) and stratification is done according to fracture type (AO-OTA type A vs. type B/C) and radial nerve status (total/subtotal motor palsy vs. no palsy). Standard follow-up visits at 6 weeks, 3, 6 and 12 months are arranged. Later follow-up visits are arranged at 2, 5 and 10 years for the study purpose. Patients fill evaluation forms and clinical and radiological assessments are made. The physiotherapist doing objective functional measurements is blinded to treatment method. Both study groups receive physiotherapy after the initial treatment.
The purpose of the study is to find the dose of rapidly administered ketamine in 3 different pediatric age groups (2-5, 6-11 and 12-17) for abscess drainage and fracture reduction. Ketamine is the most common drug administered to children to facilitate painful procedures in the emergency setting because it achieves potent sedation, pain relief and amnesia with minimal adverse cardiopulmonary effects.(1-5) However, the 1-2 hour recovery period (1,6) associated with standard ketamine administration guidelines(7) strains work flow because it requires bedside one-on-one nurse monitoring in a treatment room, tying up these limited and valuable resources. Consequently, a combination of two other drugs, propofol + fentanyl (P/F), with recovery of 20-30 minutes, is rapidly gaining popularity for procedural sedation despite more frequent respiratory depression, apnea and hypotension caused by this technique.(2,4,8,9) The investigators believe recovery associated with our novel method for administering ketamine is significantly shorter than with the standard larger dose more slowly administered ketamine technique(7). Through the investigators clinical experience, the investigators have found rapid infusion of smaller than standard doses of ketamine safely achieves the drug's sedative effect, with the benefit of more rapid recovery due to the use of a smaller dose. However, this novel technique challenges published beliefs that time of recovery from ketamine sedation does not differ significantly with the dose administered, within the usual dose ranges, and that rapid infusion may cause respiratory depression, similar to that seen with other classes of sedative-analgesic drugs.(7,10) the investigators believe the slow infusion recommended by standard guidelines(7) requires a larger ketamine dose necessary to achieve effective sedation, and, consequently, prolongs recovery. It is the prolonged recovery that has prompted increased use of other less safe but briefer sedatives, such as propofol/fentanyl. By demonstrating patients recover rapidly with new ketamine technique, without increased adverse cardiopulmonary effects, the investigators will provide clinicians with an important new method for ketamine procedural sedation. The investigators believe clinicians will prefer more rapid recovery ketamine technique because it is safer and reduces pain and distress better than the propofol/fentanyl combination for sedation. The investigators complete proposal requires two steps. In Step One, this proposal, the investigators will determine the minimum effective dose of rapidly infused ketamine that achieves deep sedation for at least 5 minutes in 95% of children (ED95). Two groups of patients will be studied: one group is patients undergoing abscess incision and drainage and the other group is patients undergoing fracture reduction in our Emergency Department. The investigators believe that the ED95 is different for both the groups as the severity of pain is different. The investigators will compare the safety and recovery times to published standard ketamine techniques. In the following study, Step Two, the investigators will compare this novel technique, in a blinded randomized trial using the ED95 ketamine dose determined in Step One to the standard ketamine technique to determine if the novel technique results in significantly shorter recovery without an increase in the frequency of adverse effects. The study the investigators are proposing in this submission is Step One only.
After vertebroplasty, many patients will suffer from 2nd fracture in the vertebral column. With analyzing of the images done right after the 1st vertebroplasty, we can define the parameters from different imaging and they can be predictors of the future fracture.
