There are about 9745 clinical studies being (or have been) conducted in Israel. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a single center, 3 arms, prospective randomized controlled open study to determine the impact of luteal phase support on pregnancy rates in ovarian stimulation and IUI cycles with recombinant FSH in patients with unexplained infertility and mild male factor. Patients will be randomized into 3 groups: 1. Luteal support with progesterone only (they will received vaginal P gel (Crinone 8% vaginal gel; Serono, Israel) 2. Luteal support with estrogen + progesterone [(Crinone 8% vaginal gel; Serono, Israel) and Estrofem 4mg]. 3. No luteal support
In this study the investigators hypothesize that infused combinations of oxytocin and ergometrine will exhibit fewer cardiac and neurological side effects than equipotent infusion of oxytocin alone. In order to perform this study the investigators perform the following steps: 1. The investigators validate a quantitative measure of uterine tone as our primary endpoint. 2. The investigators use this endpoint measure in order to determine equipotential doses of different tocotonic drug regimens, based on the ED50 for each. 3. Using equipontial ratios based on the ED50, the investigators compare hemodynamic and other side effects of these tocotonic drug regimes. Plasma levels of oxytocin will be measured.
This is an open multicenter study, evaluating a new operative technique in femur neck fractures. The treatment consist of augmentated nails in cases of subtrochanteric or inter fracture due to osteoporosis.There two routine surgical techniques in femoral neck fractures: 1. Insertion an intramedullary nail (without augmentation) to the bone. 2. insertion a nail and metal plateto the bone. The major disadvantage of these methods is the relative high rate (4-10 precentages) of failure because of the femur head bone which is very brittle and osteoporotic. This new approach enables the nail a better grip as a result of the cement augmentation which consists of PMMA (Polymethyl methacrylate). The investigators main goal is to evaluate the use of this surgical technique
The purpose of this study is to find if adding oral pain relievers as DYPIRON and TRAMADOL in addition to the local anesthesia injection, can help reducing the pain intensity in patients who diagnosed as Suffering from peritonsillar abscess (PTA)and treated by incision and drainage .
Purpose of this study is to compare the image quality and diagnostic accuracy obtained with ultrafast solid state short SPECT in comparison with the routine SPECT protocol.
tDCS is a noninvasive brain stimulation technique that utilizes low amplitude direct currents applied via scalp electrodes to modulate the level of cortical excitability.Several studies have demonstrated that tDCS applied over the sensory-motor cortex has been able to decrease pain sensation and to increase pain threshold in healthy subjects and in chronic pain patients. The aim of this study was to test whether daily sessions of anodal tDCS repeated for 5 consecutive days may be effective in reducing pain in a large number of chronic pain patients. The cathode is usually applied over the right forhead above the eye. The aim of the study is to test whether daily sessions of tDCS repeated for 5 consecutive days will influence on ophthalmologic parametrs.
The purpose of this study is to determine the level of agreement between QuantiFeron -TB Gold test (QFT-G)and Tubeculin skin test (TST)for screening of latent tuberculosis in patients suffering from psoriasis.
Objective/Rationale: The investigators objective is to demonstrate that an intervention program based on motor learning principles can be applied to train subjects with Parkinson's disease (PD) who suffer from freezing to walk in a way that minimizes the occurrence of freezing. Since sufficient motor learning capabilities are preserved in PD, the investigators hypothesize that an intervention program that targets the time periods just prior to an approaching freezing episode can modify the walking strategies so that the episode will now be averted. Project Description: The freezing burden will be quantified in subjects with PD before and after 6 weeks of training. Two types of interventions (20 subjects in each group) will be tested: 1) Open-loop group (OLG); 2) Closed-loop group (CLG). Each session of the OLG training includes walking courses aimed at provoking freezing episodes. The experimenter will trigger an auditory rhythmic stimulation (RAS) in walking conditions likely to invoke freezing (e.g., turning) and the subject will learn to synchronize his/her gait with the auditory cues, i.e., to keep the walking pace and coordination and, as a result, to avoid freezing. Similar principles will apply for the CLG training; however, the RAS will be elicited automatically by a device that recognizes an approaching freezing episode. Relevance to Diagnosis/Treatment of Parkinson's Disease: If even partially successful, the investigators will show, for the first time that freezing of gait is amenable to motor learning and that appropriate training with external cueing can alleviate these motor blockades. While future studies will be needed to further assess long-term efficacy and other important questions about clinical efficacy and the mechanisms involved, this study should go a long way towards improving the investigators understanding of freezing of gait and its amenability to appropriate therapy. Anticipated Outcome: The investigators anticipate that after intensive training, the central nervous system (CNS) of subjects with PD will be able to anticipate impending freezing episodes based on awareness of the environmental conditions (e.g., an approaching turn) and/or based on sub-conscious response to a deteriorating gait pattern. As a result, an automated motor response that paces and coordinates gait will be internally triggered by the CNS and the approaching freezing episode will be averted. The overall freezing burden will therefore decrease in trained subjects.
Single dose tranexamic acid (TA) before dacryocystorhinostomy (DCR) operation: a prospective, double blind, placebo controlled study. The study hypothesis: TA in DCR might reduce the intraoperative and postoperative bleeding in DCR surgery, and might reduce the duration of the surgery.
The purpose of the study is to determine a possible input of C11-Choline PET/CT in identification and localization of a parathyroid adenoma (PTA). Preoperative localization of a PTA has been previously documented in multiple series, and is usually based on scintigraphy and on US. Currently, the conventional technique for localization of a PTA is a dual-isotope scan with Tc99m-MIBI and Tc99m pertechnetate. This study is acquired over at least 3 hours, includes two i.v. injections and the patient has to stay 15-30 min per acquisition under the camera. In addition, there is no anatomical imaging and further correlation with US is usually recommended. In contrast, PET/CT study with C11-Choline takes as long as 10 min., includes one injection, and provides data of higher resolution of functional (PET) and anatomical imaging (CT). Furthermore, dosimetric data shows that the total effective dose from Tc99mMIBI and Tc99m pertechnetate injection is (without CT): 0.5957 rem; and from C11-Choline injection and CT of a chest is: 0.3128 - 0.8628rem.
