All clinical trials

This is a multi-center, prospective, controlled study. MS patients (1° group: 30 patients in relapse; 2° group: 30 patients in remission) and age/sex-matched healthy controls (3° group: 30 subjects) will be enrolled in the study. Patients' disability level will be evaluated by EDSS and MSFC. Patients and controls will be tested for either coagulation/complement (C3, C4, C4a, C9, fibrinogen, factor VIII and X, D-dimer, protein C, protein S, antithrombin, factor II, aPTT, von-Willebrand factor), soluble markers of endothelial damage (thrombomodulin, Endothelial Protein C Receptor), antiphospholipid antibodies, lupus anticoagulant, complete blood count, viral serological assays or microRNA microarray. Patients will undergo dynamic susceptibility contrast-enhanced MRI using a 3.0-T scanner to evaluate CBF, CBV, MTT, lesion number and volume.

SAM-COVID is a retrospective cohort study that aims to determine the impact of immunosuppressive drugs and immunoglubulins in the outcome of patients with COVID-19.

To understand the association between facial demodicosis and ocular demodicosis, we plan to enroll patients with facial demodicosis, ocular demodicosis, or both, in order to analyze their clinical presentations, the density of Demodex infestation over facial skin and eyelashes, and possible risk factors of the two diagnoses.

The objectives of this study are to characterise immune responses in people with CoV-SARS-2 infection and use this knowledge to advance vaccine design, treatment options, and diagnostic reagents. Eligible participants will include people diagnosed with SARS-CoV-2 infection, and may include recently returned travellers and non-travellers in the community presenting to tertiary hospital healthcare facilities. Recruitment will be opportunistic, and sampling intensity may vary depending on the phase of the outbreak. Participants can be enrolled at any timepoint (up to 6 months) following diagnosis of SARS-CoV-2 infection (COVID-19). Blood samples and clinical data will be collected.

In Egypt, the prevalence of end stage renal disease in pediatric population has never been estimated on a national scale. The patients at end stage renal disease encounter oral and dental problems that emphasize regular and careful screening . In Egypt, the prevalence of oral findings is not studied so we conduct this study to study the oral findings among a group of pediatric patients at end stage renal disease either on haemodialysis or after kidney transplantation.

This is a prospective study in patients receiving allogeneic stem cell transplantation. The blood samples on Day-14, -7, 0 and every 7 days until D100 were collected together with clinical data. In the final analysis, cytokines and biomarkers analysis will be carried out and compared between patients in No aGVHD and grade II-IV aGVHD.

Patients with ulnar impingement are often coexisting with patients with distal ulnar and ulnar joints with a type of sigmoid notch, and ulnar shortening surgery is one of the most useful and long-lasting treatments for the treatment of ulnar impingement. Some theories point out that if ulnar shortening surgery is performed on patients with distal oblique ulnar incisional ulnar joints, it may lead to accelerated degeneration of distal ulna and ulna articular joints, resulting in worse wrist function. Some theories have pointed out this Instead, surgery will cause joint remodeling and adaptation, but no long-term studies have confirmed this. Therefore, this study plans to evaluate the long-term radiological and clinical outcomes of ulnar shortening surgery performed on patients with preexisting inverted sigmoid notch to determine whether this surgery will cause accelerated distal degeneration of the phalangeal joints or Reshaping of joints and clinically corresponding changes in results.

Rationale. Coxitis in AS is inflammation of hip(s) affecting significant number of patients. It is associated with worse function and more expressed axial disease requiring hip replacement at end-stage. Number of studies dedicated to coxitis treated with TNF alpha inhibitors is very limited. Primary objective. To evaluate change of functional impairment in AS patients with coxitis from baseline to 12 months of therapy with golimumab by BASFI in daily clinical practice Study design. This study is a non-interventional prospective observational cohort study conducted in multiple centers across Russia. Study population. Patients with ankylosing spondylitis (according to the modified New York criteria) with coxitis newly prescribed golimumab during the course of usual clinical care will be enrolled and followed prospectively for 24 months with data collection at the approximate time points: baseline (pre-treatment) and consequent every 6 months. Patients will receive golimumab as prescribed in regular clinical practice. Statistical Methods. Quantitative variables will be tested for normal distribution using the Shapiro-Wilk test. The hypothesis of equality of variances will be tested using Levene's test. Quantitative variables matching a normal distribution will be described in terms of the mean ± standard deviation, and values outside of the normal distribution as medians, 25% and 75% quartiles. Qualitative variables will be presented in the form of percentages of the absolute value N. Sample Size and Power Calculations. Sample size calculation is based on data from GO-RAISE registration study in which golimumab was evaluated in patients with AS. The baseline BASFI was 5.0 which changed by mean (± SD, standard deviation) -2.5 (± 2.12) at week 52 (approximately 12 months). The analysis of the data shows that the minimum necessary sample size should be 18 patients to show a statistically significant change of BASFI from baseline to 12 months. On this basis and considering that the dropout rate over the two years is expected to be 30%, we decided that the necessary number of patients to be included into protocol should be 39 individuals. It is expected that around 27 patients will be included in the patient set completing the study. Power of the study is 90% with formula evaluation P = 1-β where P is power and β is type 2 error = 10%.

Children having selective ophthalmic artery chemotherapy for retinoblastoma under general anaesthesia may experience troubles during the procedure. The troubles are transient, may be severe and include hypoxemia, hypotension and bradycardia. All children having such trouble always fully recovered without any sequelae or prolonged length of stay. The investigators suspect that these phenomenons are caused by transient pulmonary hypertension.The objective is to see whether transient pulmonary hypertension and right-sided heart failure is present during theses phenomenon by trans-thoracic echocardiography.

to date there is no detailed examination of the root and root canal system of maxillary first and second premolars in an Egyptian subpopulation. in this study the investigators do an Observational analysis of available records of cone-beam computed tomography (CBCT) of root and canal morphology in the permanent maxillary first and second premolars in this population
