All clinical trials

310 singleton pregnancies (22-35 weeks) enrolled into the study. We assessed sonographically the fetal larynx in an axial plane through the mandible and observed the fetal deglutition movements .

Force enhancement (FE) describes the phenomenon of strength potentialization of a muscle cell or the complete muscle during and after active extension compared to the strength of an isometric contraction with same muscle length. The underlying physiological mechanism of this phenomenon is not completely known today. In vitro trials indicate that the interaction of an active and a passive component on the cellular level are responsible for the higher strength measurements. So far FE could be shown in vitro and in vivo on muscle fibers and small human muscles. Further research is needed for verification of the existence of FE in voluntary motor activity in everyday life. In order to approach this objective the investigators will scrutinize the functionality of the deliberately activated musculus (m) quadriceps femoris during and after active extension on the basis of in vivo studies.

A questionnaire will be used in order to find out the reasons for poor adherence for long-term treatment in children with asthma. The hypotheses is maternal factors including the knowledge that asthma is a chronic disease and fear to administer inhaled steroids are major obstacles for appropriate adherence.

Research Protocol Assessment of Hip, Spine and Lower Limbs Digital Radiograph Measurements in Pediatric Population: using PACS integrated Computer Software (TraumaCad from OrthoCrat ™). Introduction The integration of the PACS system into many medical institutions created a plethora of digital measurements to assess anatomic and deformity parameters for torso and limbs. A number of commercial digital software is being offered to supply the medical practioner with tools to assess normal and pathological bony architecture land marks. The relevant architecture of the pelvis (hip joint), spine and the length and alignment of lower limbs may be measured using these digital software's. The validity and accuracy of digital work in comparison to conventional radiographs has been studied recently, mainly with lower extremity axial alignment, the digital length and anatomical angles measurements were found to be more reliable in terms of intra observer reliability than conventional radiographs (1, 2). Study purposes To compare the, accuracy and reliability of specifically designed digital software (TraumaCad from OrthoCrat ™) measurements using wizard guidance, to those produced by using the tool bar (ruler and angle guide tools) of the DICOM folder. To assess intra and inter observer reliability of the TraumaCad software for different pediatric orthopaedics conditions. Methods *Twenty hip joins radiographs (AP views) of patients who suffer from Cerebral Palsy (10) and Developmental Dysplasia of the Hip (10) will be measured using the TraumaCad software hip joint wizard, and than again using basic tools of the DICOM folder. **Twenty spinal scoliosis radiographs (AP and Lat views) will be measured using the TraumaCad software templates. ***Ten digital radiographs of long leg standing (AP views) from normal and from patients with deformities will ne analyzed for length and angular differences using the LLD wizard. The following parameters will be measured *Hip joint radiographs: Acetabular Angle, Central Edge Angle, and Reimer's Index **Spinal radiographs: Cobe Angle (AP views), Coronal Balance, Sagital Balance. ***Long standing views: length of Femur and Tibia, mLDFA, mMPTA, mLDTA, JLCA, (the "Baltimore numbers"). All measurements will be taken by 4 senior orthopaedic surgeons after consensus conference for the technique. Intra observer reliability will be tested by repeating the same set of measurements on 2 different dates, after all radiographs are randomly mixed and done at least 2 days apart. High resolution single computer will be used for all measurements by all participating surgeons. The intra and inter observer reliability for the hip joint measurements will be calculate to compared between TraumaCad software wizard and the DICOM measurements tools. All measurements using TraumaCad software will be analyzed for intra and inter observer reliability using accepted statistical tools. The study will be supervised by the department of statistics of TAU for maximum statistical significance. 1) Sailer J, Scharitzer M, Peloschek P, Giurea A, Imhof H, Grampp S.

The Fast-MI registry was designed to evaluate the "real world" management of patients with acute myocardial infarction (MI), and to assess their in-hospital, medium and long-term outcomes

The purpose of this study is to determine if endoscope with NBI(narrow banding imaging)can detect intestinal metaplasia( consider pre malignant condition) and use a targeting biopsy in case of suspected intestinal metaplasia

Data will be extracted from the NTUH medical records database, geocoded according to the street address so that the case number, incidence, etc could be mapped. The spatial data would be used to detect aggregation of TB cases, existence of "hot spots" and then determine if they may merit further investigation or may have occurred by chance. The results from these GIS-based analyses would address local variations in TB incidence and transmission.

In this prospective study the investigators compared common bile duct injuries (CBDI) following laparoscopic cholecystectomy (LC) and open cholecystectomy (OC) procedures, 35 patients in each group. To date, no detailed study concerning this matter has been published. LC - CBDI in comparison with OC - CBDI more often concerned young females with a narrow CBD, they were located closer to the liver hilus, and they were more extended.
