This study was designed to identify the incidence, injury patterns, and actual medical costs of occupational-related falls in Qatar, in order to provide a reference for establishing fall prevention guidelines and recommendations.Retrospective database registry review in Level 1 Trauma Center at Tertiary Hospital in Qatar.During a 12-month period between November 1(st) 2007 and October 31(st) 2008, construction workers who fell from height were enrolled. A database was designed to characterize demographics, injury severity score (ISS), total hospital length of stay, resource utilization, and cost of care.Data were presented as proportions, mean ± standard deviation or median and range as appropriate. In addition, case fatality rate and cost analysis were obtained from the Biostatistics and finance departments of the same hospital.There were 315 fall-related injuries, of which 298 were workplace related. The majority (97%) were male immigrants with mean age of 33 ± 11 years. The most common injuries were to the spine, head, and chest. Mean ISS was 16.4 ± 10. There was total of 29 deaths (17 pre-hospital and 12 in-hospital deaths) for a case fatality rate of 8.6%. Mean cost of care (rounded figures) included pre-hospital services Emergency Medical Services (EMS), trauma resuscitation room, radiology and imaging, operating room, intensive care unit care, hospital ward care, rehabilitation services, and total cost (123, 82, 105, 130, 496, 3048,434, and 4418 thousand United States Dollars (USD), respectively). Mean cost of care per admitted patient was approximately 16,000 USD.Falling from height at a construction site is a common cause of trauma that poses a significant financial burden on the health care system. Injury prevention efforts are warranted along with strict regulation and enforcement of occupational laws. HubMed – rehab


The magnitude of errors associated in measuring the loads applied on an assistive device while walking.

Measurement of the loads exerted on the limb is a fundamental part of designing of an assistive device, which has been done by using strain gauges or a transducer. Although calculation of loads applied on an orthosis coefficients achieved from calibration is a standard way, most of researchers determined the loads based on available equations. Therefore, the aim of this research is finding the accuracy of this method with respect to calibration. Some strain gauges were attached on the lateral bar of a reciprocal gait orthosis. It was calibrated for axial force and the anteroposterior and mediolateral moments. The outputs of strain gauge were changed to force, and moments based on the coefficients were achieved from calibration using available equations, while 5 normal subjects were walking with the orthosis. There was a significant difference between the force and moments exerted on the orthosis during walking based on the two methods (mostly extension moment and compression force). The results of this research indicated that the output of strain gauge varies based on the methods of calculation. As calibration the gauge is a standard method, it is recommended to calibrate it before use. HubMed – rehab


Oral rehabilitation of a patient with ectodermal dysplasia with prosthodontics treatment.

Ectodermal dysplasia (ED) is a rare, congenital disease that involves the sweat glands, scalp hair, nails, skin pigmentation, and craniofacial structure. Oral symptoms of ED include multiple tooth abnormalities (such as hypodontia, anadontia, impacted teeth, and peg-shaped or conical anterior teeth) and lack of normal alveolar ridge development. A 12-year-old male patient, in the absence of any other systemic abnormalities, exhibited typical characteristics of ED, visited our department of pedodontics and preventive dentistry at Panineeya Mahavidyalaya Institute of Dental Sciences and Research Centre. In the clinical and radiographic evaluation, it was occurred that he had only maxillary and mandibular first molars in his mouth. A maxillary and mandibular denture with clasps for retention was fabricated for prosthodontic rehabilitation after considering his growth and the number and condition of his present teeth. At the 18-month follow-up no major complications occurred and further future treatment included implants retained fixed partial dentures. HubMed – rehab

Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation.To propose and describe an alternative methodology for teaching and learning the principles of cutaneous surgery in a medical undergraduate program by using a chicken-skin bench model.One instructor for every four students, teaching materials on cutaneous surgical skills, chicken trunks, wings, or thighs, a rigid platform support, needled threads, needle holders, surgical blades with scalpel handles, rat-tooth tweezers, scissors, and marking pens were necessary for training simulation.A proposal for simulation-based training on incision, suture, biopsy, and on reconstruction techniques using a chicken-skin bench model distributed in several sessions and with increasing levels of difficultywas structured. Both feedback and objective evaluations always directed to individual students were also outlined.The teaching of a methodology for the principles of cutaneous surgery using a chicken-skin bench model versatile, portable, easy to assemble, and inexpensive is an alternative and complementary option to the armamentarium of methods based on other bench models described.
