To compare between bifocal and trifocal external bone transport by ilizarov ring external fixator as a treatment method for posttraumatic bone defects more than 5cm in lower extremities regarding: - External fixation index . - The need of any further surgical procedures as debridement at docking site , the need of cancellous bone graft or the use of internal fixation. - Functional outcome, complication rate as well as limb length discrepancy.
Retinal imaging is a corner stone in diagnosis of most retinal disorders. Standard imaging techniques e.g. fluorescein angiography and color fundus photography have a lot of limitations including limited resolution, invasive nature in cases of fluorescein angiography, and inability to segment the retina, accordingly, and only 2D image is provided. Optical coherence tomography angiography (OCTA) is a recent noninvasive imaging technique that allows for volumetric visualization of eye vasculature. OCTA has shown promise in better elucidating the pathophysiology of several retinal vascular diseases. Swept-source OCTA uses long wavelength ̰ 1,050nm, which can penetrate through deeper layers of the eye and can traverse opacities of media such as cataracts, hemorrhages and vitreous opacities. Optical coherence tomographic angiograms can further be manually or automatically segmented with preprogrammed software to highlight individual layers of the retina, optic nerve head choriocapillaris, and choroid. The user can either analyze en face images extending from the inner limiting membrane to choroid or use automated views to locate a vascular or structural lesion within the retina. Different quantitative metrics has been extracted from enface OCTA images including vessel density, FAZ area, choriocapillaries flow deficit, intercapillary area and fractal dimension. These metrics are helpful in evaluation the retinal perfusion and used by physicians to assess various retinal vascular disorders. Although some previous literatures had discussed the repeatability of OCTA metrics, however, comprehensive evaluation of widely used metrics in various retinal condition has not be done. Additionally, recent data suggest that various methods of calculation of these metrics my yield final different results of the same metric.
Contactless and widely available health monitoring technologies are of growing interest in the context of the worldwide COVID-19 pandemic. Remote photoplethysmography (rPPG) is a well-studied technology that interprets variations in skin colour related to blood flow which, when analysed with complex mathematical algorithm, generates vital sign readings. This technology has been refined and embedded in a smartphone app designed to acquire heart rate, respiratory rate and oxygen saturation using a front-facing smartphone camera. Preliminary data comparing the accuracy of smartphone rPPG readings with conventional vital sign monitor readings are promising; however, less than 5% of the population studied in the app development phase had oxygen saturation levels below 95% making it impossible to ensure reliability in these populations. The goal of this study is to compare readings acquired using this rPPG app with the readings from hospital grade, Health Canada approved vital signs monitors used in healthcare settings with a focus on subject with low oxygen saturations. We will also study other sociodemographic and clinical features that may influence the accuracy of the readings. This will be achieved by recruiting consenting adults presenting to care in acute care settings and a designated COVID outpatient clinic. Vital signs will be acquired using the rPPG app and conventional hospital vital sign monitors simultaneously. Readings will be repeated within 2-5 minutes when time permits. Statistical analysis will be performed to analyze the findings and determine the accuracy and precision of the rPPG app readings. It is expected that the vital sign readings acquired with the rPPG app will be almost identical to those acquired using hospital-grade monitors for all subjects regardless of age, gender, skin colour, COVID status and relevant comorbidities.
We evaluated the clinical effect of Butorphanol on postoperative analgesia by observing the vital signs of patients, general condition of newborns and pain assessment.
There is no validated tool in quality-of-life assessment of women with endometriosis in Croatia. First aim is to validate Endometriosis Health Profile-5 (EHP-5) before implementing this questionnaire in clinical practice. After validation, we will prospectively follow women with endometriosis through whole process - pre- and postoperatively.
The aim of this study is to evaluate the knowledge level of healthcare professionals such as physicians, nurses, physiotherapists and nutritionist about published COVID-19 guidelines. The listed healthcare workers are take part in the primary treatment of the Corona virus infected patients in hospitals. Therefore the knowledge of the world wide spreading Corona Virus and its effects for the human being is should be known for the effective treatment and for raising public awareness.
This study aims to evaluate the effect of robotic rehabilitation through training on a robot-assisted orthostatic board and neuromuscular electrical stimulation (NMES) on functionality in post-stroke patients. In this randomized controlled trial the patients will be allocated to a control group (which will receive conventional physiotherapy) or or to intervention group (which will receive conventional physiotherapy and robotic rehabilitation). Interventions will occur every day in the hospital phase and three times/week after discharge, totaling 18 sessions.The groups will be evaluated prior to any physiotherapy intervention, in the 10h session and at the end of six weeks of treatment (or 18 sessions).The following outcomes will be measured: functionality, peripheral muscle strength, muscle architecture and echogenicity, spasticity, cardiorespiratory repercussions, mobility, disability and dependence, quality of life and time of hospital stay.
The incidence of infectious complications in hematological malignancies is higher than that in children with solid tumors, which may be related to the type and dose intensity of chemotherapy regimens used in hematological tumors. The treatment of childhood cancer has changed in the past few decades: intensive treatment and good supportive treatment can improve the 5-year survival rate of children. The aim of this study was to evaluate the efficacy and safety of prophylactic use of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) after chemotherapy in children with hematological malignancies.
Hemophagocytic syndrome (HPS), also known as hemophagocytic lymphohistiocytosis (HLH), is an immune mediated life-threatening disease. There is no uniform recommendation for salvage treatment of HLH. Based on the results of current clinical trials, the marketing situation of the drug in China, and the use requirements of pegylated recombinant human granulocyte stimulating factor(PEG-rhG-CSF), this study was conducted in patients who received the DEP rescue therapy or dexamethasone combined with VP-16 maintenance therapy. The aim of this study was to evaluate the efficacy and safety of PEG-rhG-CSF(Jinyouli®) for the recovery of neutropenia after chemotherapy in patients with hemophagocytic syndrome.
