Filter by:This study aimed to investigate methods for promoting infection control, reducing tissue edema, and preventing excessive spread in diabetes foot ulcers in the necrosis stable stage. Additionally, it sought to explore potential indications for the use of aseptic wound care liquid dressings in these ulcers, with the goal of obtaining evidence-based medical data on their clinical efficacy. Participants will be assigned with a 1:1 ratio into intervention group and control group. Participants in the intervention group will be irrigated with sterile liquid dressing for each wound treatment on the basis of clinical standard treatment protocols for 2 weeks, until the end of the 2-week observation period. Participants in the control group will be irrigated with normal saline for each wound treatment for 2 weeks on the basis of the clinical standard diagnosis and treatment plan, until the end of the 2-week observation period.
The study is designed to assess the efficacy of vancomycin powder and dilute povidone-iodine lavage (VIP protocol) in reducing the PJI after primary Total Hip Arthroplasty (THA) and Total Knee Arthroplasty (TKA). We hypothesized that VIP protocol provides superior reduction of periprosthetic joint infection (PJI) rates after primary THA and TKA compared with diluted povidone-iodine (PI) protocol.
The aim of this study is to assess in vivo the efficacy of Er,Cr:YSGG/diode laser and Diode/EDTA on bacterial count in root canal treatment in an evidence-based clinical trial. The null hypothesis being tested is that there is no difference in total bacterial count reduction between conventional irrigation and the two types of lasers used. Thirty patients are equally divided into 3 separate groups : - Group A (Conventional): 2.5% NaOCL and 17% EDTA. - Group B(Dual): saline along with Er,Cr:YSGG laser and diode laser combination - Group C(Combined): saline along with 17% EDTA and diode laser combination Microbiological analysis will be done for both aerobic and anaerobic bacteria using Colony forming units. All data will be collected, tabulated, summarized, and statistically analyzed.
This is a post-marketing surveillance on Medacta Shoulder System
The goal of this study is to evaluate the efficacy and safety of Recombinant Human Tumor necrosis Factor-α Receptor Ⅱ Fusion Protein （rhTNFR-Fc）in the treatment of patients with acute Gout.
During the performance of oncoplastic surgery and skin-sparing or skin-nipple mastectomy there is a significant loss in the perfusion of the cutaneous envelope of the breast, which can produce areas of vascular suffering of the skin that sometimes cause necrosis of the same. Skin necrosis is the most important adverse event in oncoplastic and reconstructive surgery of the breast, since it causes delays in adjuvant treatments to surgery, worsening of the cosmetic result, and, on occasions, loss of the implant and reconstruction. Indocyanine color green (ICG) angiography has been proposed as a diagnostic alternative to determine the vascular perfusion of the skin envelope of the breast during surgery, which would allow the removal of tissue at risk of necrosis to avoid this complication during the postoperative period. However, the scientific literature does not currently allow an adequate assessment of this diagnostic procedure due to the absence of prospective studies that have evaluated its sensitivity, specificity, and predictive values. The objective of this prospective study is to evaluate ICG angiography of skin flaps of the breast and the surgeon's decision in women with breast cancer or at high risk for breast cancer undergoing oncoplastic surgery or mastectomy with the help of skin or skin-nipple. Based on the results of this study, the sensitivity, specificity, and predictive values of this technique for the prediction of adverse events during the postoperative period will be established.
The goal of this observational study is to compare postoperative results between patients who had total hip arthroplasty (THA) with and without the use of a computer navigation program. The main questions this study aims to answer are: - Can using computer navigation produce better THA implant placement? - Can using computer navigation make surgery more efficient? Participant data collected include their postoperative x-rays and total operative time.
The goal of the Shoulder iD™ Primary Reversed Glenoid Outcomes Clinical Study is to collect safety and performance data on the commercially available Shoulder iD™ Primary Reversed Glenoid device. The study will learn about standard device use in adult patients who have a functional deltoid muscle and massive and non-repairable rotator cuff tear. The main questions it aims to answer are: - What is the average improvement in patient-reported shoulder function after 2 years when compared to before the surgery, and - What is the rate of surgical revisions needed over a 10 year period Patients will be asked to will be asked to regularly attend their check-up visits with their surgeon (including having x-rays or CT images taken to check their shoulder and implant), to complete questionnaires to report how their shoulder is doing, and to tell their surgeon when they notice any changes.
The main objective of the study is to evaluate the safety, performance and clinical benefits of the Persona implant and its instrumentation in primary total knee arthroplasty
Contrast-enhanced magnetic resonance imaging is the most widely used examination for detecting the presence of brain metastasis. Functional sequences such as perfusion weighted imaging makes it possible to differentiate tumor recurrence from cerebral radionecrosis. However, this imaging technique may exhibit limitations, especially for brain lesions consisting of a mixture of necrotic tissue and tumor progression or depending on the location of the lesion in the brain. The use of 18F-DOPA PET is another option available to oncologists. Many studies on gliomas showed the superiority of this imaging technique over contrast-enhanced MRI. However, this imaging solution has been very poorly studied for brain metastases. The new PET technology equiped with silicon detectors makes it possible to obtain greater sensitivities than those of previous generations. It also make possible to obtain images in very short acquisition times. After injection, the hardware allows to obtain the perfusion kinetics of the lesion thanks to a very short temporal sampling (i.e. three seconds). The main objective of this pilot study is to evaluate the association between early activity measurements (< 4 minutes post-injection) of 18F-FDOPA in PET and the differential diagnosis between radionecrosis and recurrence of cerebral metastases treated by radiotherapy.
