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.
The etiology of infertility in the majority of patients with poor response to ovarian stimulation remains unknown. This study will investigate the role of immune cells (T cells, B cells, dendritic cells and NK cells), that constitute the immune system which normally fights infection and cancer. We, the investigators, have found that specialized NK cells that help with new blood vessel formation, are found in the fluid surrounding the egg during IVF, only in patients with good response to ovarian stimulation. We now wish to expand our studies and correlate our findings to ovarian blood flow , as measured by 3D ultrasound and to the presence of other cells in the immune system.
Zinc and vitamin d deficiency are associated with a state of inflammation/atherosclerosis. There are studies demonstrating an association between vitamin d deficiency and respiratory illnesses. Both zinc and vitamin d are associated with oxidative stress and inflammation.
Thermal, or infrared, energy is the part of electromagnetic radiation that an observer perceives as heat. Infrared thermography allows us to visualize temperature distribution of the human body and has been used in medical practice since the 1950s. In current study we would like to examine the ability of infrared thermography to detect acute appendicitis, ovary torsion and inflammation, and testicular torsion and inflammation.

To determine the possible association of prothrombin fragments 1+2 elevation with incidents of pulmonary embolism in patients with COPD exacerbation.
Intranasal injection of epinephrine is used routinely during endoscopic sinus surgery (ESS) to reduce bleeding in the nasal mucosa and thereby improve visualization of the surgical field. However, systemic absorption of epinephrine via the nasal mucosa is often accompanied by cardiovascular side effects during the early postinjection period, putting in risk patients with cardiovascular morbidity. Evidence indicate that topical administration of epinephrine achieves similar hemostatic effects compared with injection of epinephrine, while avoiding systemic adverse effects. We wish to conduct a prospective controlled trial assessing the hemostatic and hemodynamic effects of intranasal injection compared to topical application of epinephrin during ESS, in order to evaluate whether the previous could be avoided due to its untoward effects. We hypothesize that topical administration of epinephrine provides a hemostatic effect not inferior to that of intranasal injection while minimizing hemodynamic instability during ESS.
To examine the satiety effect after eating of Okara.
Ataxia-telangiectasia (AT) is a rare genetic disorder characterized by gait disorders, neuromotor dysfunction, eye abnormalities and immune deficiency. AT patients are vulnerable to cancer and infection and usually die during their 2nd or 3rd decade due to these complications. The main cause of death is respiratory infections because these patients are known to have severe type of immunodeficiency. Consequently, pneumonia is the most common infection seen in AT patients, and is usually caused by S. pneumoniae. Therefore, a routine schedule of pneumococcal vaccine is highly recommended in AT cases where immunoglobulin replacement therapy was not already initiated. Until recently, AT patients were immunized with the pneumococcal polysaccharide vaccine (PPV23, Pneumovax® Aventis Pasteur MSD). However, data have shown that they do not respond well to these vaccines. Recently, the Israeli Ministry of Health has approved the pneumococcal 7-valent conjugate vaccine (PCV7, Prevenar®, Wyeth Lederle) for AT patients of all ages. This conjugate vaccine is known to stimulate the immune system through a different mechanism and the response is expected to be higher. The approved Israeli schedule for immunization of AT patients includes children older than 2 years that are entitled to receive 2 doses of PCV7 (8 weeks apart) boosted by PPV23, eight weeks after the second dose of PCV7. Assessment of the antibody response of such pneumococcal vaccination protocol in AT patients has never been performed. The "Safra" Children's Hospital is the national multi-disciplinary center caring for AT patients. Approximately 50 patients from all over the country (including Jewish, Druze, Bedouin and other Muslim patients - 3 of whom are Palestinians) are followed in the clinic on a monthly basis. Approximately 20 AT patients are not receiving IVIG replacement therapy, therefore are entitled to receive pneumococcal vaccination as stated above (mean age 10.6, 3 -23 years, 3 less than 5 years) The aim of this study is to evaluate the responsiveness, determined by specific antibody production, of AT patients receiving this new vaccine protocol.
Treatment of patients with one cycle of induction chemotherapy to select for organ preservation of the larynx has been proven as a standard approach. When compared to historical controls. The investigators propose to study patients with a similar treatment strategy (i.e. one cycle of induction chemotherapy followed by two more chemotherapy cycles, in advanced nodal disease, followed by chemoradiation for those responding to the initial chemotherapy. Those who fail to respond or fail in radiation will directly undergo surgery. The novelty of the proposed study is that non responders and failures will be given the opportunity of larynx preserving supracricoid laryngectomy. The investigators will attempt to reduce toxicity from induction chemotherapy and improve potency with the use of docetaxel/cisplatin/5-fluorouracil (TPF) in place of the standard regimen of cisplatin and 5-fluorouracil (PF). Emerging data demonstrates that induction regimens containing triplets with platinum, 5-fluorouracil, and taxanes produce higher response rates and less overall toxicity when compared to induction strategies utilizing PF
Uraemic pruritus (UP) remains a frequent and distressing problem in patients with advanced or end-stage renal disease. Its intensity ranges from sporadic discomfort to complete restlessness during both the day- and night-time and its distribution varies significantly over time. Many attempts have been made to relieve this bothersome symptom in affected patients, however with generally limited success. Incidence of UP varies widely between studies and seems to decline over the last 30 years (from 85% in the 1970s and 50-60% in the 1980s to a 22% in the 2000s) (Gunal AI). We use Pregabalin for the relief of diabetic neuropathic pain in patients on haemodialysis in our centre. In addition to neuropathic pain, several of our patients have complained of pruritus and after Pregabalin treatment, their pruritus has promptly and completely resolved. Accordingly, we intend to conduct a double-blind, placebo-controlled, crossover trial to assess the effectiveness of Pregabalin in chronic UP.
