Filter by:The primary aim of this study is to investigate the effect of Internet-delivered Acceptance and commitment therapy for PTSD and comorbid chronic pain using a randomized controlled trial with waitlist control.
In 230 patients undergoing mastectomy, the investigators will compare opioid-free anesthesia (OFA) versus conventional opioid-based anesthesia in terms of chronic pain. The enrolled patients will be randomly assigned into two groups with 1:1 ratio. Chronic pain will be evaluated at 1 year after mastectomy based on the Breast Cancer Pain Questionnaire (BCPQ). Baseline pain sensitivity test and psychologic evaluation will be done before operation.
Thoracotomy and video-assisted thoracic surgery procedures are frequently performed in thoracic surgery. It is widely accepted that thoracotomy causes severe acute pain. This prolongs the discharge time of the patients, and increases the frequency of postoperative pulmonary complications and postoperative morbidity. Postoperative acute pain may cause chronic thoracotomy pain in the later period, and may adversely affect the quality of life of the patients. Video-assisted thoracic surgery (VATS) has become the standard procedure in minor and major lung surgeries. Postoperative pain is seen in patients undergoing VATS, although it is not as severe as after thoracotomy. As in thoracotomy, this affects the postoperative pulmonary complications and the discharge time of the patients. Likewise, this pain can cause chronic pain. In this study, it was aimed to analyze the symptoms of chronic pain in the 3rd and 6th months postoperatively in patients who had undergone thoracic surgery.
Lumbosacral radicular pain is present in around 40% of cases of low back pain. It is usually caused by irritation and inflammation of the nerve root, and patients typically experience pain radiating from the back to the lower limb in the distribution of the affected spinal nerves. Epidural steroid injection is the most commonly used pain-relieving procedure in the world. However, the analgesic efficacy of epidural steroid injection appears to be modest and duration limited. Platelet rich plasma (PRP) is an emerging treatment option for chronic pain. It is currently used for treating musculoskeletal pain conditions such as osteoarthritis and tendinopathies. While epidural steroids reduce pain by reducing inflammation, PRP promotes the healing of nerve injury and reduces neuropathic pain. However, the effect of transforaminal epidural PRP versus epidural steroid specifically for lumbosacral radicular pain is unclear. In this study, a double blind, randomized controlled trial will be performed to compare the effect of transforaminal epidural PRP versus epidural steroid for pain relief in patients with lumbosacral radicular pain.
The EPPIC (Easing Pelvic Pain Interventions Clinical Research Program) study evaluates an ultra-brief, 4 session cognitive behavioral pain treatment transdiagnostic in design for urologic chronic pain syndrome (UCPPS) with clinical and practical advantages over existing behavioral therapies whose length and focus limits their adoption by clinicians and coverage for mechanistically similar comorbidities. A theoretically informed, practical, empirically grounded approach will systematically unpack CBT's working mechanisms, clarify for whom it works, ease dissemination, appeal to patients, providers, payers, and policy makers in the COVID-19 era favoring low resource intensity treatments, and reduce cost and inefficiencies associated with high intensity therapies whose complexity, length, and scarcity restricts uptake and impact.
Investigators will test a novel protocol for starting BUP (buprenorphine-naloxone) treatment. The BUP microdose induction protocol has participants start very low doses of BUP without stopping other opioids that they are taking. The treatment as usual (TAU) has participants stop other opioids and experience opioid withdrawal before starting BUP. Investigators propose to test BUP microdose inductions vs. TAU in a randomized controlled trial.
The goal in this study is to investigate TEST (Transcranial Electric Stimulation Therapy) for chronic pain. It requires an inpatient stay on our research unit of about a month. The study is designed to address the cognitive and emotional aspects of chronic pain and other conditions that often accompany this disorder, such as major depression or drug use.
Refractory chronic pain represents a serious and limiting health condition which does not respond to standard pharmacological therapy. Thus, it emerges the necessity of new techniques to treat these group of diseases, such as the transcranial electrical stimulation (tES). This procedure induces a low-intensity electrical current through the scalp to modify the excitability of brain cells, thus facilitating changes in neural networks which may be dysfunctional in some chronic pain patients. The main objective of this research is to test the efficacy of two tES techniques, differentiated by applying direct or alternant electrical current, to reduce the pain intensity and to increase pain thresholds of these patients. Besides, intervention is implemented at home for patients themselves thanks to a portable and convenient stimulator device, after one training session provided by technicians. Researches can supervise the compliance of the treatment remotely, as the stimulator has a permanent connection with their computers. A home-based approach means a more comfortable and accessible treatment alternative for patients, since they do not have to attend to clinics everyday to receive the stimulation; the advantages become even more relevant in the pandemic context, since the risk of being infected is radically minimized. Despite the main purpose is to test the efficacy of tES to improve the pain suffered by patients, many other areas are considered as secondary end points for being intrinsically linked or affected by the disease, such as the interference in daily tasks provoked by pain, mood disorders (depression/anxiety), fatigue, life quality, physical functioning and sleep quality; these last two variables are measured with actigraph wristwatches, apart from specific questionnaires. Lastly, endogenous modulatory pain mechanisms are examined through sensory tests, namely Conditioned Pain Modulation and Temporal Summation of pain.
This study investigates how adults prescribed opioids for chronic noncancer pain respond to invitations to try non-opioid options of massage therapy, yoga therapy, chiropractic and physical therapies. Due to the COVID-19 pandemic, these options will be available via telehealth consultation visits using a computer or smartphone with internet connection. The investigators will measure effects on pain, pain-related symptoms, and opioid use over time using a single-group design.
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a collective term referring to disorders which is characterized by lower urinary tract symptoms, including bladder pain/discomfort, frequent urination without evidence of bacterial infection. The etiology of IC/BPS is still uncertain, and most current treatment for IC/BPS are only symptoms control. Our previous study revealed Epstein-Barr virus (EBV) infection presented in the IC/BPS bladders and involved the pathogenesis. Hence, using anti-viral medication valacyclovir for the patients with IC/BPS might have clinical efficacy.
