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.
Bicycle riding is associated with related diverse urogenital symptoms ranging from genital numbness to erectile dysfunction (ED). Very little is known about the quality of sperm in cyclists and whether a connection exists between erectile dysfunction and azoospermia.
In this prospective open armed study we aim to see if bilateral hernia repair using a mesh alters the spermatogram (sperm count) or testicular volume.
This study's first aim is to widen the knowledge of the characteristics of delayed sleep phase disorder (DSPS) by focusing on the circadian rhythms of appetite regulation factors and their phase relations to the cycles of sleep-wake, melatonin, cortisol and body temperature. This study's second aim is to assess the influence of forced morning awakening, as a daily struggle faced by DSPS patients, upon the synchronization of these variables in DSPS patients. The investigators hypothesize that the chronic incompatibility between the endogenous sleep-wake rhythm of the DSPS patients and the morning wakefulness, as a social demand, may impair the synchronization between the different rhythms, as findings indicate in normal subjects under jet lag. And finally, the third aim of the study is to assess the influence of successful treatment with melatonin upon the phase locations of circadian rhythms of studied measures and the synchronization between them. These measures will be assessed in a controlled study, for 36 hours (sampled every 2 hours) under three distinct experimental conditions: first, under free sleep-wake conditions (ad-libitum bedtime and arousal); second, under restricted sleep-wake conditions (enforced morning wake-up); and finally, after 12 weeks of melatonin treatment.
This randomized phase III trial is studying fludarabine, cyclophosphamide, and rituximab to see how well they work compared to fludarabine and cyclophosphamide in treating patients with B-cell chronic lymphocytic leukemia.
Recurrent Aphthous Stomatitis (RAS) of the oral mucosa is a common and painful condition. Despite advances in therapeutic means there is still necessary to find a way to alleviate the local pain and discomfort induced by the mucosal ulceration. The hypothesis was to study the effectiveness and acceptance of a herbal adhesive tablets in the treatment of RAS. Participants in the study will be examined for oral lesions, will be instructed how to apply the oral-tablet, and will be interviewed during the follow-up period up to one week after the application.
The purpose of the study is to compare two device settings (sets of instructions) used by the ICD. The Implantable Cardiac Defibrillator ("ICD") can be set to use one wire (top or bottom of the heart) or two wires (top and bottom). The study will compare how much time either ICD wire is used by the ICD and the status of congestive heart failure.
This trial will test the hypothesis that the addition of CF101, a novel anti-inflammatory agent, will improve the clinical condition of patients with rheumatoid arthritis who still have active joint inflammation despite taking methotrexate for at least 6 months.
The increase in life expectancy in the 21st century has resulted in a major growth in the prevalence of age-related diseases and conditions. Depression has been found to be the most prevalent among the various mental disorders in later life. It was emphasized that depression in the elderly is a persistent or recurrent disorder resulting from psychosocial stress or physiologic effects of disease and can lead to disability, cognitive impairments, intensified symptoms of other medical conditions and increased utilization of health care services. Due to the rapidly aging population, depression is a serious public health concern that has a great impact on quality of life and may lay a considerable burden on the health care systems. However depression among the elderly may prove to be hard to diagnose since in aged persons depressive symptoms are often masked by somatic complaints or by cognitive impairments. Consequently depression is often under diagnosed and the patients continue to visit constantly the nurse or the physician without getting an adequate answer to their problem. For that reason over utilization of health care services may be an indicator to the presence of undiagnosed depression. The purpose of this study is to examine the relationships between socio-demographic variables, high primary care utilization and depressive symptomatology among aged patients.
Hallux valgus is a common deformity of the big toe, defined as medial deflection of the first metatarsal bone along with lateral deflection of the first toe. Surgery has been shown to be beneficial when compared to orthoses or no treatment. While generally effective, surgery entails significant post-operative pain, inflammation and edema, and several weeks of limited mobility. This will be a double-blind, randomized, placebo-controlled study comparing the homeopathic drug Traumeel S with placebo in pain reduction after surgical Hallux valgus correction. 80 patients, over the age of 18 years, undergoing surgical correction of unilateral hallux valgus will be enrolled in the trial. The patients will be randomized to two groups, one receiving oral Traumeel S and the other oral placebo tablets. Patients will take active or placebo medication for 13 days or until they have a NRS score of 3 or less for 2 consecutive days. Pain will be reported daily by the patient on the patient diary, using an 11-point numerical rating score (NRS-11) during 13 days post-operatively. They will also be asked to report daily consumption of primary and "rescue" analgesics for 13 days post-operatively. Patients will be contacted daily by the research assistant to encourage compliance and to record their daily NRS and analgesic consumption in the CRF. Patients will be evaluated by physicians at six and 13 days postoperatively for redness and compliance.
The aim of the study is to evaluate the effect of cognitive behavior group intervention with cancer patients and their family members. Around 80 cancer patients and their family members will participate in group intervention and will be compared with 80 controls.
