Filter by:Background: Headaches is one of the most common complaints of children in the ED and the treatment of pediatric migraine is largely based on extrapolation data from adult studies, limited pediatric trials, clinical experience and expert consensus. Despite the fact that dexamethasone has already been proven effective to reduce recurrence and is currently used in treating adults with migraine, no studies have looked at its use in the treatment of childhood migraine where relapse rate of about 50% are described in the 48h following successful treatment in the ED. Objective: To examine the effectiveness of parenteral dexamethasone at preventing migraine recurrence in children and to study the risk factors for migraine relapse after discharge from the ED. Methods: This a randomised, double-blind, placebo-controlled clinical trial among all children 8 to 17 years of age with a presumptive diagnosis of acute migraine and treated with a standardized protocol in the ED of the CHU Ste-Justine, a tertiary care pediatric hospital. After the parenteral administration of prochlorperazine or metoclopramide and diphenhydramine, the patients were randomised to receive either dexamethasone or a placebo. They were excluded from the intervention if they had a known allergy or absolute contraindications to receiving parenteral corticosteroids, if they were already on a corticosteroid regimen or if they did not respond to the initial abortive migraine therapy. All included patients were discharged on a 48-hour course of naproxen and with a headache diary to fill out and return. The primary outcome was the incidence of relapse in the 24-48h following discharge from ED. The secondary outcomes evaluated were the mean level of pain, the use of rescue medication after ED discharge, the return rate to the ED or the visit to a health care professional within 7 days including hospitalisation. The associated symptoms, the adverse events after parenteral corticosteroids and the risk factors for migraine relapse were also evaluated. A telephone follow-up was made to ensure the headache diary was completed and returned.
The purpose of this study is to investigate efficacy and safety of Chidamide Combined With Cyclophosphamide,Prednisone,Thalidomide in Treatment of Fragile Patients With Relapse/Refratory Peripheral T Cell Lymphoma :a Phase II,Single-arm,Open-label, Muti-center Study
The purpose is to evaluate if sodium fluoride PET in patients having already undergone a choline PET negative for bone extension (non-metastatic status) modifies the status of patients concerning the existence or not of bone metastases. Secondary purposes are: - To evaluate if detection of bone metastasis by sodium fluoride PET, not detected by choline PET, leads to change of treatment - To evaluate inter-technique concordance (choline vs sodium fluoride PET) of results (metastatic status and number of lesions) - To evaluate the inter-judge concordance of interpretation of sodium fluoride PET - To study the discordance of metastatic status of 2 techniques.
Nearly three-quarters of patients with Crohn's disease have small bowel involvement and 80% of them will have complications that will require a surgical procedure, usually an ileocolonic resection with ileocolonic anastomosis. The rate of recurrence at the anastomosis site and in the ileum after surgery, whether symptomatic or not, is high, at least 60% in one year and 80% within three years. The gold standard for monitoring being ileocolonoscopy, endoscopic surveillance is recommended in these patients, once between 6 to 12 months after surgery and then every 2 years. The MRI enterography is a validated technique for the assessment of small bowel Crohn's disease. The enterography MRI is a validated technique for the assessment of small bowel Crohn's disease. The MRI enteroclysis was evaluated in two studies compared to endoscopy, with excellent performance in terms of recurrence detection sensitivity and suggested as an alternative to it to avoid an invasive procedure repeated in these patients. The MRI enterography (without enteroclysis) does not provide as good distension of the bowel loops as MRI enteroclysis because it relies on the principle of oral ingestion prior to the examination of large amounts of liquid. However, it is much better tolerated by the patient, does not involve radiation that exists with enteroclysis, is much simpler to use and requires no special equipment to magnetic fields.
Add-Aspirin aims to assess whether regular aspirin use after standard curative therapy can prevent recurrence and improve survival in individuals with non-metastatic common tumours. The question will be assessed in four different tumour types (breast, colorectal, gastro-oesophageal and prostate) by means of parallel cohorts within an overarching trial protocol. Eligible participants will be randomly assigned (double-blind) to either aspirin 100mg, aspirin 300mg or a matched placebo, to be taken daily for at least 5 years. Disease recurrence and survival will be assessed, along with adherence, toxicity, and other potential effects of aspirin (eg. cardiovascular). There is a large body of evidence indicating that aspirin has anti-cancer effects. Meta-analyses of cardiovascular trials of aspirin have shown short-term effects on cancer mortality and a decrease in risk of metastases, suggesting a role for aspirin in the treatment as well as prevention of cancer. Additionally, large observational studies of individuals taking aspirin after cancer treatment have shown improved disease-specific and overall mortality for specific tumour types. In the treatment setting, the risks of side effects associated with aspirin are expected to be outweighed by potential benefits. However, this has not yet been assessed in a randomised trial. As a low cost, generic and widely available drug, which is generally safe, if aspirin is shown to be effective, it could have a huge impact on cancer outcomes globally.
The aim of this fMRI study is to investigate neural indices of relapse in cannabis dependence. The development and maintenance of drug addictions have been associated with deficits in cognitive control, craving and impaired stress regulation. Therefore, neural markers of brain processes underlying the beforementioned components will be studied. Subsequent follow-up drug use interviews will reveal associations between relapse in cannabis dependence and alterations in brain networks of cognitive control, craving and stress.
HNSCC is the 4th highest incidence of cancer and 6th of cancer death of the males in Taiwan. Because the patients were mainly middle-aged male, the disease eventually resulted in a huge loss of labor force, productivity and a huge burden of family supports and medicinal costs. Currently, the primary treatments of HNSCC are mainly surgery, radiotherapy, chemotherapy or targeted therapy or concurrent chemoradiotherapy. Compared to oral cavity cancer, patients with pharyngeal cancer would possibly harbor HPV infections and have better treatment outcomes, prognosis and survival with clinically significance; however, the investigator's reports showed quite the opposite prognostic value in oral cavity cancer. The inconsistent data urges us to investigate further. Fortunately, in recent years, The investigator have developed a new method for isolation and detection of CTCs in HNSCC patients.The investigator's data found that high level of CTCs in patients with HNSCC and might be associated with disease prognosis, response to treatment and distant metastasis. This novel tool enhances the studies addressing on metastases or recurrence process in HNSCC patients. However, the investigator did not focus whether if the dynamic change of CTCs and specific surface markers on CTCs, such as P16+ CTCs are clinically meaningful. Therefore, in the first year, the investigator will utilize the investigator's developing device and protocol to isolate high-purity CTCs to further identify P16+ on CTCs. In the following 2 years of the project, the investigator will enroll 150 freshly diagnosed patients with oral cavity, oropharyngeal, hypopharyngeal and laryngeal cancer at all stages (75 P16+ and 75 P16- patients) and 30 healthy donors for cell line tests, and then analyze CTCs, background white blood cells signals, and their initial biopsied tissue for P16 positivity test. Further statistical tests with clinical conditions (disease status, treatment effects, progression or distant metastasis and death) will be performed to elucidate their clinical significance.Hopefully, the investigator will clarify the clinical significance of circulating P16 expression status on CTCs by this study and provide a new biomarker for clinical cancer care.
This study aims to visualize the implanted mesh in vivo by MRI in 20 patients at 1 month and 12 months post-operatively. Moreover, we want to evaluate the safety and efficiency of non-penetration mesh fixation techniques using pre-designed ENDOLAP 3D visible mesh placement versus mesh fixation using a synthetic LiquiBand Fix 8 glue for laparoscopic treatment of groin hernias. A total of 100 male and female patients will be entered in the trial in Maria Middelares Ghent, for which an inclusion period of 24 months is anticipated. Four surgeons of the department of surgery will screen all eligible consecutive patients for inclusion in the study. They will inform all patients about the surgery and the follow-up with MRI scan thereafter.
MEDIACONNEX study propose a new way of connectedness for adolescents after a suicide attempt: it is based on the sending of SMS (or mail or other new media), over a period of 6 months after their suicide attempt (SA), in order to allow them to recourse to the care more easily and so to limit the risk of suicidal recurrence. The MEDIACONNEX study will be a multicenter controlled randomized trial (East of France) and there is a funding from the Hospital. The proposal trial will test the hypothesis that adolescent suicide attempters who are receiving SMS (or mail or other new media) from the unit of care in addition to the usual care will do less SA recurrence, than those who are receiving the usual care. The primary objective is to determine whether the use of SMS (or mail or other new media) to keep in touch with adolescent suicide attempters in addition to the usual care, compare to usual care, will reduce the delay of recurrence of suicide attempt during 6 months after the SA.
This clinical trial is designed to evaluate the efficacy of single immediate intravesical chemotherapy instillation in the prevention of bladder recurrence after diagnostic ureteroscopy for upper tract urothelial carcinoma (UTUC) patients.
