Aim of the work - To identify the prevalence of CMV infection in patients with steroid-refractory ulcerative colitis. - To assess the clinical and endoscopic conditions in these patients.
assessment of very rapid virological response and rapid virological response as predictors of response to sofosbuvir and daclatasvir in treatment of cirrhotic and non-cirrhotic patients with HCV, eligible to treatment.
To describe the prevalence of undernutrition in infants and children admitted to Assiut university children hospital and to describe risk group and decrease length of stay in hospital.
Background: The increase of chronic diseases has reached an increase in the suffering of advanced diseases and an inability of health care systems to give access to the population that suffers them. In this context are people with advanced cancer who are in palliative care and the family caregivers. Uncertainty in illness in palliative care and quality of life are two concepts that are altered in the patient's family caregiver in palliative care. Objective: to examine the feasibility and acceptability of a nursing intervention to reduce the uncertainty in illness and improve the quality of life of family caregivers of patients with cancer in palliative care. Methodology: Phase II clinical trial, the ratio of recruitment, follow-up of participants as well as satisfaction with the intervention will be evaluated as primary outcomes. As secondary outcomes, the possible effect of the intervention on the uncertainty in illness and the quality of life of the family caregiver will be evaluated. This study will be carry out in a health care institution in Medellin-Colombia.
The aim of this study is to investigate the role of functional evaluation for predicting clinical outcome in patients with coronary chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI), and to evaluate the clinical evidence for the using of fractional flow reserve (FFR), coronary flow reserve (CFR), index of myocardial resistance (IMR) and dynamic single photon emission computed tomography (D-SPECT) in these patients.
The primary outcome measure of the study is to demonstrate the safety and tolerability of GSK1070806 in the Behcet's disease population at 24 weeks, with biochemical and clinical efficacy and mechanistic studies to further explore the pathogenesis of Behcet's disease important secondary and exploratory outcomes.
Distraction osteogenesis is a powerful technique for creating new bone during significant lengthening of the mandible without the need for bone grafting and associated donor site morbidity. The idea of distraction osteogenesis was largely abandoned by many until the 1950s. Ilizarov minimized complications by performing a corticotomy with minimal disruption of the surrounding blood supply and using a system of tension ring fixators to control the distraction in multiple planes. Through a series of experimental studies and clinical applications, Ilizarov established the foundation of distraction osteogenesis and its role in orthopedic management. Applications in craniofacial surgery were first seen in 1973, when Synder et al applied the approach to mandibular lengthening in a canine animal model. Almost another 20 years passed before McCarthy and colleagues published, in 1992, the first report of mandibular lengthening in 4 children with congenital mandibular deficiency, 3 with hemifacial microsomia, and 1 with Nager syndrome. Thereafter, its role rapidly expanded to the midface and nearly all classic approaches to craniofacial reconstruction. In general, mandibular distraction can be performed in the ramus for ramus lengthening, in the mandibular angle for downward and forward advancement, or in the mandibular body. Ramus or gonial angle distraction are mainly used to treat facial asymmetries as in hemifacial macrosomia. Severe mandibular retrognathia can be classified as congenital or acquired. Congenital abnormalities that are associated with severe mandibular retrognathia or micrognathia include craniofacial syndromes such as hemifacial microsomia, Pierre-Robin syndrome, Treacher-Collins syndrome, and Nager syndrome. Adult patients with craniofacial syndromes may have undergone previous surgery at an earlier age, but unfavorable postsurgical growth or skeletal relapse may have occurred. Severe mandibular retrognathia also can develop following maxillofacial trauma and mandibular fractures, which may have occurred in an adult or as a child Condylar fractures occurring at an early age can result in subsequent bony and/or fibrous temporomandibular joint ankylosis and/or deficient mandibular growth, also adult patients with complications from previous mandibular tumor resection and reconstruction can also present with acquired severe mandibular retrognathia that may require distraction osteogenesis as well. Despite the advantages of extra-oral distraction devices in the hands of clinicians (application for very small children, simplicity of attachment, ease of manipulation, bidirectional and multidirectional dis- traction), patients are apprehensive about wearing bulky external appliances because of the social inconvenience and the potential of permanent facial scars, these disadvantages and limitations were the primary force driving the evolution of mandibular lengthening and widening toward the development of intra-oral devices. However nowadays both internal and external distractors are used in a variety of indications in these cases each of the two types of distractor devices has its own advantages and disadvantages. Aim of the work: The aim of this study is to compare external and internal distraction devices for mandibular lengthening in terms of bone lengthening, patient comfort, and complications.
Dermoscopy is a non-invasive method that allows evaluation of colors and microstructures of the epidermis, the dermoepidermal junction, and the papillary dermis not visible to the naked eye. These structures are specifically correlated to histologic features. The identification of specific diagnostic patterns related to the distribution of colors and dermoscopy structures can better suggest a malignant or benign pigmented skin lesion. The use of this technique provides a valuable aid in diagnosing pigmented skin lesions
The purpose of this study is to evaluate the safety and effectiveness of transcranial magnetic stimulation (TMS) therapy in moyamoya patients who received surgical revascularization.
Lumbar Quadrant Blockade is a recent analgesic technique consisting of the injection of local anesthetic around the lumbar square muscle. It was initially described as a technique for abdominal wall analgesia, but later studies have increased the range of indications for laparoscopic and lower limb surgeries. There are several techniques described but with differences in the literature at the point of injection and volume of anesthetic. The exact mechanism of visceral analgesia has not yet been determined. The objective of this study is to determine the dispersion of local anesthetic as a variable dependent on the volume of local anesthetic and injection site and elucidate the mechanisms of analgesia.
