Filter by:The purpose of this study is to determine whether the compound lidocaine cream is effective in preventing postoperative agitation in patients with endotracheal intubation for general anesthesia.
Glucocorticoids therapy exposes the patient to an increased risk for diabetes morbidity. However, there is no proven preventive therapy. GLP-1-RA has shown to improve glucose metabolism in healthy volunteers treated with glucocorticoids. We assume that GLP-1-RA will improve glucose metabolism in patients with high risk for diabetes morbidity, treated with glucocorticoids.
This is a Prospective, open-label, parallel, multi-center, Phase III randomized trial to evaluate the efficacy and safety of video-assisted thoracoscopic segmentectomy versus Lobectomy in treating patients with Lung adenocarcinoma in situ or with microinvasion.
We hypothesize that using the ViSiGi™ Calibration Tube System in patients undergoing LSG will: 1. enhance delineation of the stomach anatomy and the surgeon's appreciation of the extent of gastric volume to be removed; 2. increase the safety profile of the patient (i.e., reduce the likelihood of accidental stapling of the orogastric tube or bougie); 3. reduce the incidence of OR contamination/infection transmission; 4. streamline OR workflow, resulting in reduced OR time; and 5. ensure consistent and reproducible staple lines.
Investigate the supersaturation and precipitation behaviour of diclofenac in the stomach of healthy volunteers.
Plerixafor has been intensively used in recent years for harvesting autologous stem cells from lymphoma and myeloma adult patients. Its use is indicated after failure to harvest with GCSF alone. Nevertheless, in the pediatric population its appliance is less well established and the indications are less well confirmed .Several disease states and diagnoses may prompt the anticipation of difficulties in harvesting stem cells using GCSF only. Such patients may benefit utilizing plerixafor in first-line rather than exhausting the stem cell niche with GCSF alone and only than go for plerixafor as second-line rescue procedure. In this study we propose to examine the applicability and feasibility of harvesting autologous stem cells by means of GCSF + plerixafor in first-line measure for pediatric patients with specific indications.
Epidural analgesia is the most effective form of labor pain relief. Low doses of local anesthetic (freezing solutions) in combination with opioids (narcotics) are commonly used as epidural solutions to provide pain relief. Low dose local anesthetic solutions with opioids for labor have been shown to decrease motor block (leg weakness or temporary paralysis), without affecting labor pain relief. However, onset of pain relief can be delayed with these low dose solutions. The standard epidural solution used at Victoria Hospital is a low dose of local anesthetic called bupivacaine mixed with fentanyl, an opioid, for labor epidural pain relief. There is some evidence that the addition of more fentanyl to the epidural bolus dose of bupivacaine at the start of labor epidural analgesia can speed onset of pain relief. Both medications are safe for you and your baby. This study will investigate whether the addition of different doses of fentanyl (20 mcg, 50 mcg and 100 mcg) to the epidural bolus dose speeds onset of pain relief. The study hypothesis is that the onset of epidural labor analgesia will be shortest with the larger fentanyl epidural bolus.
This study investigates the benefit of using chlorhexidine gel as an antimicrobial agent in orthodontic patient to reduce caries risk and the possible consequential effect of this use on the orthodontic brackets used for the treatment. The investigators hypothesis is that chlorhexidine gel use can reduce caries risk in orthodontic patients with out causing damage to the bonded ceramic or metal orthodontic brackets.
Recurrent respiratory papillomatosis in children caused by HPV 6,11 can be a life threatening condition resulting in surgical interventions. The maturing and disintegrating papillomas are the sources for the subsequent HPV relapses and immunization might slow down or even prevent this ongoing process. After an initial immunological and ear-nose-throat (ENT) assessment children with at least 3 relapses in their patient history will be vaccinated with 4-valent HPV vaccine according to the following schedule: 0., 2., 6. months. It will be followed by an immunological and 3 ENT examinations to assess response to vaccination.
Soft tissue injury leads to significant deformity in size, shape and body contour. Adipose tissue, continues to be the tissue of choice in repairing soft tissue defects due to traumatic or other defects. Current autologous fat transfer techniques, however, have a number of limitations including significant donor site morbidity, unpredictable resorption, and the potential for requiring revision. Thus, an "off-the-shelf" material that retains the mechanical and biological properties of adipose tissue would be ideal for the reconstruction. Extracellular matrix (ECM)-based biomaterials have the potential to be a non-immunogenic biological scaffold for adipose tissue engineering for repair of soft tissue defects. Our collaborators have recently generated a novel tissue-derived material to improve soft tissue reconstruction. The final, processed adipose tissue does not contain cellular components, yet retains the native architecture and bioactivity of the original adipose tissue. The tissue is then further processed into particles to create an injectable implant. In preclinical models, we have demonstrated that human adipose tissue can be decellularized by mechanical processing with preservation of matrix ultrastructure. Histologic analysis two-weeks after implantation into rats showed minimal inflammatory reaction and good tissue integration of the decellularized, dilipidized, adipose derived-ECM. The goal of the study is to 1) evaluate the safety and compatibility of the soft tissue implant, and 2) determine the efficacy of this ECM replacement in soft tissue injuries after 6 weeks. Specifically, the volume of the soft tissue defect will be determined before implantation and at multiple time points over the following 6 weeks. We hypothesize that the decellularized adipose ECM will retain at least 50% volume and surface area after 6 weeks. If our results are promising, decellularized adipose derived-ECM may be a viable alternative to autologous tissue transplantation for correction of soft tissue deformity.
