Filter by:The trial is an investigator-initiated, double-blind, randomized, placebo-controlled phase III study. After the patient has receiving information about the study and after given written informed consent, the patient will be screened. All patients are randomized to receive standardized rose hip powder or matching placebo for 3 weeks followed by half the dose standardized rose hip (or placebo) for the remaining 12 weeks of the study. The patient's medical history and demographic information will be recorded. The patient will then be asked questions in accordance to the study questionnaires, and they will also be asked to complete questionnaires regarding quality of life - and finally they be instructed on how to complete the diary. Investigator or study nurse will take telephone contact with the subject after 3 and 6 weeks of treatment, subjects will be asked about how things are going and to remember to take the capsules and whether they have completed the diary. The contact taken after 6 weeks by phone is mainly to guide the subject on how complete the questionnaires including VAS scales. The last patient visit will take place after 12 weeks. Any side effects will be reported to and reviewed with HybenVital ApS in collaboration with medical experts.
This trial will compare two oral analgesic regimens in women undergoing first trimester medical abortion with mifepristone and misoprostol. The primary study outcome is pain.
This study is to test the effectiveness of pregabalin in treating nerve pain caused by diabetes. The suitable subjects will be patients who also use an non-steroid anti-inflammatory drug for another pain which is not related to the diabetic nerve pain.
With thyroid surgery being performed as an ambulatory procedure, most recent studies concerning post thyroidectomy analgesia are focused on regional techniques such as bilateral superficial cervical plexus block (BSCPB) and bilateral combined superficial and deep cervical plexus block. But, data regarding the efficacy of BSCPB are controversial. Hence the investigators compared the efficacy of BSCPB with 0.25% bupivacaine with or without clonidine in thyroidectomy, as preemptive analgesia. The hypothesis was bupivacaine with the addition of clonidine would help in reducing postoperative pain and thereby reduce the need for postoperative analgesia.
The purpose of this study is to examine if ultrasound guided infiltration of local anesthetic solution around the hip joint will provide effective pain control after hip arthroscopy.
RATIONALE: Physical activity, diet, and counseling may help breast and colorectal cancer survivors to lose weight and improve their quality of life. PURPOSE: This phase II trial studies how well exercise, diet, and counseling work in improving physical activity and weight loss in overweight women who are breast and colorectal cancer survivors.
Pain after ambulatory surgery remains an unsolved problem in The United States and Europe. It is associated with delayed hospital discharge and it can result to an increased opioid consumption with adverse side effects. The concept of multimodal analgesic technique was introduced more than 15 years ago and several techniques have been studied over the years including non steroidal antiinflammatory drugs (NSAIDs), acetaminophen, gabapentoids, ketamine, local and regional anesthetic techniques. Histamine can have effects on polymodal nociceptors and C-fibers, producing pain which is further increased by neurogenically mediated release of substance P from afferent pain fibers. Several non-selective or H1 -selective histamine receptors antagonists have been demonstrated in animal models and clinical pain. Chia et al demonstrated that preoperative promethazine had opioid sparing properties without adverse sedative effects in patients undergoing abdominal hysterectomy. Diphenhydramine is an anti-histamine drug who has been found to be effective in reducing postoperative nausea and vomiting after ambulatory surgery but its effects on postoperative pain and other important outcomes after ambulatory surgery such as time to meet discharge criteria have not being studied. The MQOR 40 is a validated instrument that was specifically design to evaluate patient recovery after anesthesia and surgery. This instrument can be particularly valid to examine interventions which affect different spheres of patient recovery as is the case of diphenhydramine. The objective of this study is to determine a dose response effect of preoperative diphenhydramine on postoperative quality of recovery after ambulatory surgery. The use of preoperative diphenhydramine can improve patient's quality of recovery, decrease postoperative pain, opioid consumption and opioid related side effects after ambulatory surgery. The research question: Does a preoperative dose of diphenhydramine improve postoperative quality of recovery after ambulatory surgery? The hypothesis of this study is that preoperative diphenhydramine will improve postoperative pain, Postoperative nausea and vomiting (PONV), sleep which will translate in a better overall quality of recovery.
Slow axonal Kv7 potassium channels are found along unmyelinated axons and at the nodes of Ranvier of myelinated axons in peripheral nerve. As such the pharmacological activation of Kv7 channels offers a potential means of reducing the excitability of peripheral axons. To determine whether this is the case for human peripheral myelinated axons, the effect of the Kv7 channel agonist flupirtine on the electrical excitability of A fibres was examined in both isolated segments of human sural nerve in vitro and in motor axons of the median nerve supplying abductor pollicus brevis in vivo. Axonal excitability was assessed in 21 human sural nerve fascicles in vitro and in 20 volunteers in vivo using threshold tracking in QTRAC (© Institute of Neurology, London, UK). Strength-duration time constant, rheobase current, relative refractory period (RRP), post spike superexcitability at 5 and 7 ms and threshold electrotonus over the 90 100 ms period were used as indices of electrical excitability. In addition, suppression of ectopic discharge in a model of upper limb ischaemia.
Compared with performing each procedure individually, performing two combined procedures such as colonoscopy consecutive Esophagogastroduodenoscopy (EGD) cause more bowel gases, abdominal distension and post-procedure pain because of longer procedure time related to more bowel insufflated gas than one procedure. To the best of the investigators knowledge, there has been no randomized controlled trial of CO2 versus air for insufflations during combined two procedures, colonoscopy with consecutive EGD. And there are a few well randomized trials concerned CO2 insufflation in patients receiving sedation during colonoscopy. The aim of the present study was to evaluate the efficacy of CO2 in reducing post-procedural abdominal pain and distension during colonoscopy consecutive EGD and to confirm the safety of CO2 insufflation when it is used during procedure in sedated outpatients.
Oxaliplatin (Ox) is part of most treatment regimens for colorectal cancer. However, it may induce side effects, such as a specific injury to peripheral nerves called neuropathy. Ox-induced neuropathy is frequently painful. The presence of pain after its administration may hamper the full chemotherapeutic treatment of patients with colorectal cancer receiving this agent. Recently, it has been suggested that the appearance of acute neuropathy after oxaliplatin (Ox) infusion could predict the distal polyneuropathy seen some months after treatment. These two adverse events related to Ox treatment probably share different mechanistic backgrounds. However, recent experimental data suggest that both types of peripheral neuropathies are able to induce central sensitization, a major step to the occurrence of chronic pain. Pregabalin is a molecule used to teat neuropathic pain since it can diminish the peripheral sensitization seen in this painful condition. Recently, it has also been shown that pregabalin can be used to treat neuropathic pain related to Ox treatment. In the present study, we will test the hypothesis that Pregabalin administrated exclusively for three days before and three days after the Ox infusion is able to prevent the occurrence of pain secondary to both the acute and chronic Ox-associated neuropathies. In the classical FLOX chemotherapeutic regimen, Ox is infused in nine sessions during a six-month period. Patients will be followed for a year and nerve conduction tests, quantitative sensory evaluation, pain, quality of life and functional scales will be used to assess the impact of this strategy in the prevention of pain. If this strategy proves to work, this information will have a major impact in the cancer prognosis of patients with colorectal cancer since Ox will be able to administer in its full dose, and will not be limited by neuropathic side effects.
