Summary: To find out if adding medication can help treat or prevent lymphedema and/or fibrosis related to radiation therapy, in survivors of head and neck cancer. Researchers will compare these drugs to find the most effective therapy for preventing or limiting these side effects.

Summary: This study is conducted to evaluate the effectiveness and safety of ketamine infusion for pain relief after knee replacement surgery. Adult patients who have undergone knee arthroplasty will be randomly assigned to one of two groups. The study group will receive standard pain management plus a continuous infusion of ketamine using patient-controlled analgesia (PCA), while the control group will on...

Summary: Non-steroidal anti-inflammatory drugs (NSAID) are part the multimodal strategy in pain management after surgery. However, major concerns are raised in cardiac surgery given the potential side effects of NSAID with more bleeding and acute kidney injury. The investigators hypothesized that NSAID are safe in the early postoperative course after cardiac surgery with respect to contraindication.

Summary: Currently the prevalent approach to perioperative management of patients is ERAS (Enhanced Recovery After Surgery) concept. This approach includes numerous aspects, among which the perioperative use of multimodal analgesia takes one of the leading places. Within the ERAS guidelines all sorts of minimization of opioid analgesics use in schemes of postoperative analgesia are appreciated. Thus, new p...

Summary: Non-steroidal anti-inflammatory drugs (NSAIDs) are recommended in a multimodal pain management to reduce pain intensity and to spare opioid use. However, there is a controversy in its use in pleurodesis surgery as it could block the process of pleurodesis in surgical pneumothorax. In addition, NSAIDs could increase the risk of pneumothorax recurrence. The investigators hypothesized that NSAIDs are...

Summary: Total knee arthroplasty is a surgical treatment which involves replacing the damaged articular cartilage of the knee joint with an artificial prosthetic in end-stage knee osteoarthritis. Although total knee arthroplasties are mostly successful, approximately 1 in 5 patients are unsatisfied with their outcomes with 16-33% of patients of patients experiencing lasting pain following total knee arthro...

Summary: There is a lack of effective analgesic treatments to help walking patients with painful hip/knee osteoarthritis. Our team therefore imagined a new strategy lying on a multimodal rehabilitation walking program with the help of a transient intake of nonsteroidal anti-inflammatory drug (NSAID). NSAIDs are indeed known to act specifically on pain at movement, but their continuous intake would induce u...

Summary: This study aims first to assess the efficacy, safety, and effectiveness of the LUSZ COVID-19 therapy consisting of a comparative study of three different treatment approaches: antiviral, antiretroviral, and immunosuppressive IL-6 receptor antagonist, and second to identify high-risk factors and biomarkers associated with fatal outcomes in hospitalized COVID-19 patients. The study seeks to validate...
