Objective: the objective of the present randomized clinical trial is to compare changes in radiographic peri-implant bone defect fill after regeneration of peri-implant intrabony defects with a submerged versus a non-submerged protocol. Material and Methods: this project is a randomized controlled clinical trial, double blind, with a parallel groups design. Thirty-six patients presenting with peri-implantitis subsidiary of regenerative treatment will be recruited. After subjects have been given informed consent, they will be randomized to test or control group. All patients will undergo a session of non-surgical peri-implantitis therapy consisting on prostheses removal and implant debridement with ultrasounds, curettes and air-abrasive under local anaesthesia. Patients in test group will have their prostheses removed and the mucosa surrounding the affected implants will be let heal covering the implants, while patients in control group will have their prostheses installed again after the non-surgical therapy. Six to eight weeks later, all subjects will undergo regenerative treatment with the use of a bone substitute, a collagen membrane and fixation pins, and in control group tissues will heal following the non-submerged protocol, meanwhile subjects in test group will undergo submerged healing. Six months later, subjects in test group will have their prostheses reconnected to the regenerated implants. All patients will undergo periodontal and peri-implant maintenance therapy every three months during follow-up. Radiographic assessment of vertical bone level changes (primary outcome), clinical status of peri-implant tissues, changes in soft tissues margin, patient related outcomes and adverse events will be assessed at 3, 6 and 12 months after peri-implantitis regenerative surgery.
The main purpose of the study is to determine risk factors of poor bowel cleansing in inpatients after a split-dose high volume preparation with 4 liters of polyethylene glycol. The quality of colon cleansing will be measured by the Boston bowel cleansing scale (more than or equal to 2 points in each segment). The secondary aim is to design a predictive score of poor bowel cleansing.
Women with intramural myoma not reaching the endometrial cavity will be randomized to either open myomectomy or no intervention . The participants will be assessed through full history-taking with special consideration to age and the duration, type, and cause of infertility. The medical examination included general, abdominal, and vaginal examinations. Finally, an ultrasonography examination was performed to check for the presence of three or more preantral follicles and to exclude ovarian cysts. On day 3 of a natural cycle, a baseline levels of FSH, luteinizing hormone (LH), , estradiol and anti-Müllerian hormone (AMH).Ovarian stimulation was performed using a long, antagonist, or short protocol. They were assigned to one of the 2 groups according to having an intramural myoma not indenting the cavity or not. All will be followed up by transvaginal ultrasonography . When two or more follicles had reached a mean diameter of 18 mm, oocyte maturation was triggered by intramuscular administration of hCG. Embryo transfer will be done at day 2, 3 or 5 according to the circumstances.
The prevalence of cardiovascular risk in psoriasis has been reported in previous studies.Various studies have also shown that systemic treatments for psoriasis, including methotrexate, may significantly decrease this cardiovascular risk. We proposed that the addition of vitamin D may not only improve the therapeutic effect of various treatment modalities but also increase its effect on decreasing the cardiovascular risk in psoriasis. So our aim of work is to assess the Clinical improvement and cardiovascular risks in psoriatic patients after treatment with methotrexate alone with the dose of 0.2-0.5 mg/kg/week for three months in comparison to combined methotrexate with the same dose and vitamin D injection with the dose of 200,000 IU per month for 3 months. Each patient will do the following before starting treatment& after 3 months: 1. Fasting blood sugar, 2 hours postprandial and glycosylated hemoglobin 2. Liver and Kidney function tests. 3. Cardiovascular risk assessment by measuring the intima media thickness of carotid arteries using Carotid duplex and High sensitive C reactive protein measuring by particle-enhanced immunonephelometry on autoanalyzer. 4. Lipid profile (HDL, LDL, cholesterol and triglycerides). 5. Calculate body mass index and measure blood pressure 6. Albumin /creatinine ratio 7. Serum vitamin D level. Clinical response will be evaluated by Psoriasis Area and Severity index (PASI) & Psoriasis Disability Index (PDI) scores before and after 3 months of treatment
In nuclear medicine PET examinations, labeled radiopharmaceuticals are possible to enter the putamen and caudate nucleus regions of the striatum in the brain by intravenous injection. The severity of Parkinson's disease is assessed and diagnosed by quantitative analysis of the defect in the image of the radiopharmaceuticals. Clinical studies often use manual selection of regions of interest (ROIs) for quantitative analysis. However, this method causes human error and low reproducibility due to subjective factors, and also considerable time consuming. Therefore, in order to solve the above problems, this research project plans to build an automated quantitative analysis system for PET/MRI images. The quantitative analysis of the PET images is performed automatically by using the putamen and caudate ROI segmented by the MRI images. This automated quantitative analysis system is expected to improve the time-consuming, low reproducibility, and subjectivity problems of traditional manual ROI selection method, and provide a useful tool for the diagnosis of early PD. In the first year, this sub-project is expected to perform MRI T1 and 18F-FDOPA PET scanning of before and after acupuncture-treated PD patients provided by sub-project 3. In the second year, the correlation analysis will be made with the results of tremor test provided by sub-project 1 and that of the 99mTc-TRODAT SPECT image quantification provided by sub-project 4.
The investigator's purpose is to compare the effects of talocrural joint mobilization with movement versus thrust mobilization on functional performance in subjects reporting chronic ankle instability (CAI).
The main purpose of this study was to observe the pelvic floor muscle strength abnormalities of cesarean section and vaginal delivery at different time points within six months after delivery without any intervention. It was a prospective observational study, and the main study population was healthy postpartum women. Regular follow-up was conducted at 6 weeks, 9 weeks, 3 months, 4 months, 5 months and 6 months postpartum. The follow-ups included gynecological examination, pelvic floor electrophysiological indexes (category I and II muscle fiber strength and fatigue), questionnaire (ICI- Q-SF, OABSS, UDI-6), and pelvic floor ultrasound. The incidence of pelvic floor muscle strength abnormality at different postpartum time points was statistically analyzed, the high-risk factors of postpartum pelvic floor function abnormality caused by pregnancy and delivery were analyzed, and the general rules of the natural development of pelvic floor function were observed.
This study is a retrospective observational study that evaluates the rate of cardiovascular adverse events leading to hospitalization in metastatic colorectal cancer in the French county Calvados by drug exposure.
The incidence and prevalence of pulmonary disease due to Non-tuberculous mycobacteria (NTM) is increasing worldwide, and this trend has been confirmed in Korea. Treatment of NTM pulmonary disease is difficult and usually requires more than two years of long-term treatment, and the antibiotic regimens used in treatment vary. Therefore, it is difficult to track the natural history of patients with NTM pulmonary disease, to evaluate the treatment outcome, and to understand the effect of specific medicines on the outcome. Establishing a prospective registry of patients with NTM pulmonary disease is expected to accurately evaluate the progress, treatment modality, and treatment outcome of NTM pulmonary disease.
Disseminated Adv infections are associated with high morbidity and mortality in HSCT pediatric patients. The most common source of Adv infection after pediatric HSCT is the host digestive tract where latent Adv are reactivated after engraftment. We have shown in a monocentric study that Adv viral load in stools is a predictive factor of blood infection in children with digestive Adv infections. We assume that an early treatment, with antiviral drugs, such as cidofovir and brincidofovir, may avoid severe Adv infections and diseases and thus that molecular surveillance in stool is a critical factor for the control of Adv reactivations. The study has two main objectives: (i) confirming the impact of Adv viral load in stools on the occurrence of blood infection based on a multicentric prospective cohort study design; and (ii) determining the prognostic and predictive factors for efficacy and toxicity of antiviral drugs, such as brincidofovir and cidofovir.
