Filter by:The aim of the study is to determine if an experimental drug, ralfinamide, relieves your neuropathic low back pain, and if it demonstrates superiority to placebo, a "dummy" or sugar pill that contains no active medication. Ralfinamide, given as either 160 mg/day or 320 mg/day, taken in a divided dose twice-a-day, will be compared with placebo. If you are randomly (by chance) selected to receive placebo, you will receive this medication throughout the treatment period of the study. Data from this study will provide essential information for choosing the doses of ralfinamide to be used in the treatment of this type of pain and potentially other types of pain.
Recent studies have shown that women are more likely to experience pain in many medical situations. During pregnancy, women may experience an increase in pain threshold. This is thought to be related to hormonal changes and an increase in the level of certain natural pain-relieving substances in their bodies. It is important to develop simple tests to identify woman at higher risk for pain so the investigators can help them. Temporal summation is what happens when a person becomes more sensitive to a certain feeling on their skin when it is applied several times over the course of several seconds. The investigators hypothesize that pregnant women show decreased temporal summation and pain scores to venipuncture, compared to non-pregnant women.
Needle Electromyography (EMG) is an important test used to assess muscle and nerve function, but the test can be uncomfortable. It is currently not standard practice to provide any pain-relieving intervention for this procedure. The purpose of this research study is to determine whether auricular (ear) acupuncture will make EMG testing less painful.
The concept of fetal pain is becoming increasingly relevant due to growing possibilities for invasive intrauterine treatment. There is much debate as to whether the fetus is mature enough to be able to perceive pain at all. Recent studies have suggested that the fetus is at least capable of exhibiting a stress response to intrauterine needling. Intrauterine transfusions are most commonly performed by inserting a needle either in the umbilical cord root at the placental surface, or in the intrahepatic portion of the umbilical vein of the fetus. Recently, intrauterine needling in the intrahepatic vein has been shown to result in alterations in fetal stress hormones, which has been interpreted as a reaction to pain. These changes were not observed in intrauterine needling in the umbilical cord root, or after administration of analgesics to the fetus. The investigators tested the hypothesis that remifentanil provides fetal analgesia, assessed by a reduced fetal stress response. The investigators performed a randomised controlled trial comparing fetal stress response between patients undergoing intrauterine transfusions for alloimmune fetal anemia receiving remifentanil, or placebo.
Most first trimester abortions are performed under local anesthesia using either manual or electric vacuum suction aspiration. The majority of women undergoing these procedures experience some amount of pain and anxiety. The investigators seek to understand if the provision of music during first trimester abortion will reduce pain and anxiety associated with this procedure. This study will involve the use of music during first trimester abortion as an additional method of pain and anxiety control. The investigators will recruit women seeking a first trimester suction aspiration procedure primarily for elective pregnancy termination or for other related indications such as an abnormal pregnancy, inevitable abortion, or retained products of conception. Participation will be voluntary and include informed consent. Recruited women will be divided into two groups: control group (no music) and intervention (music) group. All subjects will receive routine care and standard pain control measures, including local anesthesia, during their procedure. Those assigned to the intervention group will receive a portable digital music player (iPOD™ Nano) with headphones to listen to during their procedure. All subjects will complete preoperative and postoperative pain and anxiety questionnaires in addition to a patient satisfaction survey at the end of their visit. The provider will also assess and record the subject's pain experienced during the procedure. The investigators will also measure preoperative and postoperative vital signs on all participants. Subjects will be compensated for their time and study participation will not affect any care received at the clinic. Upon completion of their visit, there will be no additional followup for this study.
The investigators will use an intradermal capsaicin injection in the forearm to induce a state of localized pain. This localized pain will be measured by different means, and analysed locally and distally by so called quantitative sensory testing. The primary endpoint of measure is the difference in pain perception with and without benzodiazepines/GABA-Agonists around the injection point of capsaicin. The secondary endpoints are to measure pain modulation locally and distally by different quantitative tests as electricity, pressure pain thresholds, and ice water tests. The investigators' hypothesis is that clobazam induces higher pain thresholds as placebo and less sedation than the control medication clonazepam.
This study is being conducted to compare the safety and efficacy of loteprednol etabonate compared to vehicle for the treatment of postoperative inflammation and pain following cataract surgery.
