Patients with multiple recession defects will be randomly oriented into to groups. The test group will recieve a relatively new technique, the VISTA technique, combined with connective tissue graft that will be harvested from the palate. The control group will recieve coronally advanced flap with connective tissue graft. subjects will be followed up for 6 months after the surgery. Any complications, that may occur, will be dealt with.
Neuromuscular blocking agents (NMBA) are among the most commonly used drugs during general anesthesia and may induce complete muscle paralysis.They are used clinically to facilitate endotracheal intubation and to optimize surgical working conditions. Incomplete recovery from non-depolarising NMBAs continues to be a common problem in modern postoperative care unit and is associated with significant risk of microaspiration and hypoventilation which leads to pulmonary complications.Recently effective reversal of neuromuscular blockade has been described by use of lower dose of sugammadex the recommended without providing adequate answer to whether the lower dose is safe enough to avoid recurrent block. Hypotheses: 1. Administration of sugammadex 0.25 mg/kg at TOF ratio 0.3 will successfully reverse (TOF=0.9) rocuronium induced neuromuscular block within 10 min. 2. Recurrent block (TOF ratio < 0.9) does not occur after reversal with low dose sugammadex 0.25 mg/kg. The primary objective of this trial is to assess the dose-response characteristics of sugammadex in reversing rocuronium induced neuromuscular block and to identify the minimal effective dose Secondary objective is to assess the safety of different doses of sugammadex (recurrent block (TOF ratio < 0.9) after reversal and the occurrence of adverse reactions) Sugammadex is a very expensive drug which limits its use i anaesthesia department. By optimising drug dosage it may have economic impact and contribute to a wider use of sugammadex to reverse neuromuscular block before extubation and thus avoid incomplete recovery. This may lead to less risk for postoperative pulmonary complications and thereby reduce morbidity and mortality after surgery.
The project aims to determine the effect of a high-nitrate dietary intervention on blood pressure and markers of vascular function compared to a low-nitrate intervention in people with elevated blood pressure. Half of the participants will receive the high-nitrate dehydrated vegetable intervention, while the other half will receive the low-nitrate dehydrated vegetable intervention.This project will advance the current hypothesis on the therapeutic link between dietary nitrate and high blood pressure, and potentially derive impactful recommendations for individuals at risk of hypertension.
The present project will therefore focus upon those processes related to visual attention and perceptual abilities and on their potential to explain reading behavior and reading problems in NF1. The main objective of this study is to clarify the specificity and heterogeneity of reading profiles and the causes of its disturbance in NF1. In particular, this project allow the investigators to study more precisely the relations between perceptual, oculomotor and visuo-attentional skills in NF1 children and reading abilities. In addition, a new oculomotor/perceptual reading aid for NF1 children will be evaluated. The investigators believe that the early intervention for perceptual, visuo-attentional or oculomotor problems may promote academic skill development.
The purpose of this study is to evaluate the safety and effectiveness of different methods of preoperative biliary drainage in patients with extrahepatic bile duct neoplasms with obstructive jaundice (hilar cholangiocarcinoma, distal bile duct cancer, and periampullary carcinoma), including PTBD (Percutaneous Transhepatic Biliary Drainage), ENBD (Endoscopic Nasobiliary Drainage) and EBS (Endoscopic Biliary Stenting).
In the case of unitary edentulousness, a dental implant is a prosthetic device fixed in the bone which makes it possible to receive a fixed dental prosthesis (crown). Peri-implant soft tissues (gums) play an essential role in the integration of the crown. Indeed, the implant gingival emergence profile provides an aesthetic integration mimicking that of a natural tooth. This implant emergence profile (EIP) is modeled during the surgical and / or prosthetic phases. The problem comes from the labile character of the EIP (Emergence Implant Profile). If the literature evokes this problem, the instability of the volume of the EIP during the impression phases has never been measured. Moreover, the three-dimensional behavior of the EIP over time (kinetic) during the acquisition phases is not known. Objective study of the mobility of gingival tissues of the implant emergence profile (IEP), using an intra-oral optical camera, would scientifically measure the labile aspect of the IEP and improve the procedure of registration of peri-implant soft tissues
A total of 29 volunteer patients will be assigned in this study. Each patient should have one resin composite restoration. The restoration will be evaluated by two diagnostic methods (D), where D1 represents visual-tactile assessment method (modified USPHS) and D2 represents light induced fluorescence intraoral camera
This research project aims at early detection, early intervention, and recovery of individuals with psychosis and prevention of their family members who are at high risk of having developmental problems and developing psychosis episode in later stages of their life. It consists of two major parts with the following study designs & aims: Part I : Developing a comprehensive and integrative psychosocial and community skills training programme (IPCST) and conducing a pilot randomised controlled trial to compare the study outcomes between the two settings in Hong Kong and Beijing. 1. To develop IPCST as an innovative intervention model targeting individuals with first or recent onset of psychosis to reduce their stay in mental hospital and bridges them to independent living in the community with optimal social and professional support; 2. To evaluate IPCST in terms of the clinical, vocational, and psychosocial outcomes of participants using a randomized controlled trial design and compare these outcomes between Hong Kong and Beijing; 3. To examine the cost-effectiveness of IPCST in the two cities; and 4. To train professionals and research personnel in Hong Kong and mainland for implementation Part II: Exploring the health needs of younger family members of individuals with early psychosis and the strategies in preventing this clinical high risk group from developing psychotic episode and developmental problems in later stages of their lives. 1. To identify the potential developmental problems or sufferings of theses younger family members living with patients with mental illness; 2. To provide baseline assessment of their psychosocial stress, mental health, and quality of life; 3. To identify interventions that may prevent them from developing psychosis and other developmental problems and improve their mental health.
The myofascial points within the trapezius muscle are hypoechogenic regions that can be depicted via ultrasound imaging. In this study we aimed to demonstrate the hypoechogenic regions within the trapezius muscle and to determine if physical therapy modalities change the appearance and size of these areas. We also wanted to explore if the presence of these areas correlate with pain.
