Surgical valve replacement is commonly performed in patients with severe aortic valve disease. In small aortic annulus, implantation of bioprosthetic valves can be associated with limited functional capacity. To avoid this condition, we changed our surgical technique to implant a larger bioprosthesis. Briefly, the prosthesis is sutured to the aortic annulus along the left and right coronary sinuses, and in a supraannular position along the noncoronary sinus, therefore allowing us to insert a prosthetic valve with a one-size larger diameter than the native aortic annulus.
To evaluate the efficacy and safety of two strengths of HY02 Ointment versus Vehicle administered twice daily for twelve weeks in subjects with a diagnosis of Inflamed Meibomian Gland Dysfunction.
This study evaluates surgical site complications in subjects undergoing revision of a total knee arthroplasty when closed incision negative pressure therapy is used to manage the closed incision, as compared to a standard of care dressing.
Knowledge of the evolution of multiple sclerosis (MS) and its long-term prognostic factors is essential to guide the therapeutic management. However, it remains partial and concerns above all data collected during the first years of the disease. The evolution towards disability can only be assessed after a follow-up of more than 10 years and does not depend solely on the initial inflammatory activity of the disease. We propose to realize a standardized clinical assessment, an optical coherence tomography (OCT) and a cerebral MRI 15 years after the first clinical manifestation of the disease. Clinical and paraclinical assessment will consist in the realization of additional MRI sequences in order to obtain more precise information on cerebral lesions (unconventional parameters). Optical coherence tomography (new generation device) will also be performed on both eyes to describe the thickness of the different layers of the retina. A clinical evaluation will be performed with the Expanded Disability Status Scale (EDSS). This study aims: 1. to describe the current clinical situation of patients (e.g. percentage of patients with moderate or severe disability) 2. to explore the associations between MRI parameters, those measured with OCT and clinical characteristics (disability) 3. to explore clinical and paraclinical prognostic factors of pejorative evolution (disability, severe cerebral atrophy, etc.)
The creation of pneumoperitoneum during laparoscopic surgery can have significant effects on the respiratory system including decreased respiratory system compliance, decreased vital capacity and functional residual capacity and atelectasis formation. Intraoperative mechanical ventilation, especially setting of positive end-expiratory pressure (PEEP) has an important role in respiratory management during laparoscopic surgery. The aim of this study is to determine whether setting of PEEP guided by measurement of pleural pressure would improve oxygenation and respiratory system compliance during laparoscopic surgery.
To evaluate in children affected by idiopathic GHD the adrenal function both at baseline and after 6 and 12 months of GH treatment.
The purpose of this study is to assess the effects on upper limb spasticity of soft splints worn during three weeks three hours a day by patients with stroke or disorders of consciousness.
The objective of this trial is to determine whether an opioid-free general anesthetic (OFA) technique utilizing ketamine, dexmedetomidine, lidocaine, and gabapentin can help reduce postoperative respiratory depression in the post-anesthesia care unit and ward in children with sleep-disordered breathing undergoing tonsillectomy when compared with traditional opioid-containing techniques. It is expected that this OFA regimen will have a measurable reduction on postoperative respiratory depression in children with sleep-disordered breathing.
The purpose of the investigation is to assess iodine status of pregnant women at week 16 of gestation targeting serum thyroglobulin as a biomarker of iodine deficiency. The investigators aim to assess whether pre-gestational initiation of iodine supplementation is more advantageous in comparison to supplementation start at the time of pregnancy detection.
