Active clinical trials for "Syndrome"

The aim of this study is to compare the surgical outcomes of the two IOL implantation methods for eyes with cataract and PEX in a single-center and with highly experienced surgeons. The goal is to acquire relevant information regarding these two IOL implantation techniques, which will help surgeons to decide which approach to choose, ultimately resulting in a benefit for patients with PEX syndrome who require cataract surgery. The main questions are: Is there a difference in lens tilt and decentration between the both methods. Is there a difference in the frequency and amount of capsular phimosis between the both methods.

The purpose of this study is to evaluate the impact of vagal nerve stimulation on patients with post COVID syndrome who have fatigue and headache.

The aim of this work is to compare continuous infusion vs on need intermittent boluses of Cisatracurium in the early management of pediatric acute respiratory distress syndrome

Background: - KSHV inflammatory cytokine syndrome (KICS) is a newly recognized disease caused by Kaposi sarcoma-associated herpesvirus (KSHV). This virus can cause cancer. People with KICS can have severe symptoms. They include fever, weight loss, and fluid in the legs or abdomen. People with KICS may also be at risk of getting other cancers associated with KSHV. These cancers include Kaposi sarcoma and lymphoma. Because KICS is a newly identified disease, more information is needed on how the disease works and what can be done to treat it. Objectives: - To collect genetic and medical information from people with KSHV inflammatory cytokine syndrome. Eligibility: - Individuals at least 18 years of age who have Kaposi sarcoma herpes virus and symptoms that resemble those caused by KICS. Design: Participants will have regular study visits. The schedule will be determined by the study researchers. Participants will provide a complete medical history and have a full physical exam. Blood and urine samples will be collected as well. People with KICS that requires treatment may get new experimental treatments. These treatments may include antiviral drugs and chemotherapy drugs, depending on the nature of the disease. Participants will have imaging studies, such as chest x-rays and computed tomography scans, to study the tumors. Bone marrow and lymph node biopsies may be done to collect tissue samples for study. Participants who have Kaposi sarcoma will have photographs taken of their lesions.

This is a 3-day study comparing pyridostigmine versus placebo in the treatment of postural tachycardia syndrome (POTS). The researchers expect pyridostigmine to improve tachycardia and stabilize blood pressure.

This is a prospective, multicenter, non-randomized, controlled intervention clinical study.Patients with severe fever with thrombocytopenia syndrome who have been clinically diagnosed and met the study inclusion criteria will be included in the study for analysis. All patients with SFTS will be assigned to different groups according to the ratio of 1:3, including the non-intervention group (conventional treatment group) and the related drug intervention group. Non-intervention group:patients received conventional treatment during hospitalization. Intervention group: Part A group: Patients received methylprednisolone 1-2mg/kg/d（or other glucocorticoid equivalent to methylprednisolone 1-2mg/kg/d) + intravenous immunoglobulin (IVIG) 0.2g-0.4g/kg/d for a total of 3-5 days. If the disease progressed after treatment, the patients was given the dose of rescue therapy (methylprednisolone > 2mg/kg/d or other glucocorticoid equivalent to methylprednisolone > 2mg/kg/d + IVIG 0.4g/kg/d) for another 3-5 days. Part B group: Patients received tocilizumab 4mg/kg once. Part C group: Patients received low molecular weight heparin 100U/kg, qd or q12h IH for 4-7 days. If the platelet count is less than 30 × 10^9/L, the low molecular weight heparin should be discontinued. All patients received conventional treatment. All patients were followed up from the end of treatment to day 28 after completion of treatment.

Decades of Tourette Syndrome (TS) neuroimaging research has revealed abnormal cortical and subcortical motor system network, hypothesized to result from maladaptive plasticity. Repetitive transcranial magnetic stimulation ([r]TMS) is a promising technology that utilizes the concept of neuroplasticity to modulate brain circuits. TMS modulation has the distinct advantage in terms of its non-invasive nature. Furthermore, unique stimulation paradigms such as intermittent theta-burst repetitive TMS (iTBS) allows for short stimulation time (<3 min). Using a sham-controlled protocol, the investigators propose modulating pre-SMA output using iTBS, based on our prior data of abnormal pre-SMA-mediated motor system regulation. hypothesize pre-SMA modulation results in increased pre-SMA-mediated motor inhibition. Enhancing these inhibitory measures with pre-SMA-iTBS provides the basis for improving inhibitory function in TS patients, leading to our long-term goal of neuro-stimulation to achieve clinical tic reduction.

This is a single-center, prospective, randomized, double-blind (pharmacotherapy), placebo-controlled, and comprehensive rehabilitation phase II clinical trial to determine the usefulness of pregabalin in a new indication (post-COVID chronic fatigue syndrome). Patients will be randomized in a 1:1:1:1 ratio to pregabalin (75-300 mg daily in two divided doses), comprehensive rehabilitation with a placebo drug, comprehensive rehabilitation with pregabalin (75-300 mg in two divided doses), or placebo (two divided doses) for 6 months (177-187 days). There will be 4 outpatient visits to the research center and 12 telephone consultations. The procedures and assessments performed as part of the study are listed in the study schedule. It is planned to include 132 patients in the study, which, assuming a 10% level of non-completion of the program, will result in the examination of 120 patients (30 in each arm). Patients will be recruited during an outpatient medical consultation with a general practitioner or neurologist, psychiatrist, psychologist or other specialists, as well as with the use of information materials in the form of leaflets and advertisements on the Internet.

Subjects with complex regional pain syndrome (CRPS) Type 1 will be randomized to receive repeated transcranial magnetic stimulation (rTMS) followed by rehabilitation or sham rTMS followed by rehabilitation. Treatment will last for 4 weeks, with the first week including 4 rTMS treatments and 2 rehabilitation treatments. Subsequent weeks will include 2 rTMS treatments followed by 2 rehabilitation treatments. Outcome measures will include pain ratings, PROMIS questionnaires, global rating of change, and grip strength or 1 repetition maximum leg press.

We will establish a cohort of 570 symptomatic chronic coronary syndrome patients undergoing 15O-water PET and assess their symptoms through repeated questionnaires. Two hundred patients with abnormal perfusion will be randomized to immediate or delayed referral to invasive coronary angiography with concomitant optimization of guideline-directed medical therapy with repeated 15O-water PET and questionnaires at 3 and 6 months. The primary objective is to compare the potential benefit of early invasive coronary angiography (ICA) versus guideline directed medical therapy (GDMT) on symptomatic relief defined as freedom of angina after 3 months following a positive [15O]H2O cardiac PET/CT in patients with symptomatic chronic coronary syndrome.
