Active clinical trials for "Hemangioma"

Infantile hemangioma (IH) is the most common benign vascular tumor in pediatric population. The characteristic natural history of this tumor is rapid growth in the first year of life and follows by spontaneous involution. However, it may cause cosmetic unacceptable. Early intervention in superficial IH may help to minimize the risk of residual aesthetic problems. Topical timolol, a non selective beta-blocker, is an emerging treatment which has been reported in efficacy and safety for the treatment of IH. However, the reported studies were case-series or small study. This study is a prospective double-blind,randomized-controlled study to evaluate the efficacy and safety of 0.5% timolol maleate solution for treatment in superficial IH. The patient will be treated with topical timolol for at least 6 months and instructed to 4 times daily apply 1-2 drop of timolol solution on the lesion and rub over the entire lesion with a finger. Photographs of the lesion will be taken at the baseline and every 1-month visit. Clinical evaluation of the treatment efficacy is carried out by 2 investigators independently to determine the change in lesion size and visual analogue scale of the lesion color. The main outcome is to evaluate the efficacy of 0.5% timolol maleate solution in treatment of infantile hemangioma compared to placebo.

Stereotactic radiosurgery is a well established treatment option for arteriovenous malformations (AVMs). The potential complications related to radiosurgery are well documented and are predominately related to radiation effects to the surrounding brain parenchyma. These risks increase with larger lesions, requiring a concommitant reduction in the amount of radiation that can be delivered. This reduction in radiation dose decreases the efficacy of treatment. The broad, long-term objectives of this proposal are 1) to determine the role of fractionated stereotactic radiosurgery in the treatment of large (>10cc) AVMs; 2) to evaluate the complication rates related to fractionating these doses compared to conventional stereotactic treatment 3) to evaluate the success rate of treating large AVMs with this protocol.

The purpose of this study is to explore the efficacy and safety of Nadolol in hemangiomas of infancy. The secondary objective is to assess the feasibility of conducting a randomized controlled trial comparing nadolol with corticosteroids and propranolol.

Hemangiomas of infancy, the most common benign tumors of infancy, are congenital or early infancy lesions characterized by a rapid postnatal growth, with high expression of angiogenic stimulators for 9-18 months, followed by slow regression for 5-9 years. Current therapies for the hemangiomas are usually restricted to more severe forms due to the risks of adverse effects, inconvenience and cost. Nevertheless, a substantial amount of the psychological discomfort and morbidity can be caused by untreated hemangiomas, especially those in the face. Recently, Imiquimod 5% cream has emerged as a safe an effective drug for several skin conditions that benefit from modulation of the activity of the immune system, such as common warts and various forms of the skin pre-cancerous and cancerous lesions. Small case reports series have suggest that it could also be useful in hemangiomas, possibly through the inhibition of the angiogenesis by local IFN production.This is a small, open label study of 16 patients to document the efficacy of the Imiquimod 5% cream in the treatment of hemangioma of infancy (primary outcome). IFN and plasma drug levels, as well as clinical examinations and blood studies, will be carried out to evaluate safety of the treatment (secondary outcome). bFGF and VEGF will be measured in blood and urine in order to study the diagnostic and predictive value of these pro-angiogenic factors in the response of hemangiomas to the treatment with Imiquimod (secondary outcome). The study is a phase II clinical trial of a once a day application of Imiquimod 5% cream, 3 to 7 times per week for a maximum of four months. The study held at the Dermatology Clinic of Sainte-Justine Hospital, and was completed within a 20 months timeframe after IRB approval.

The purpose of the study is to determine if pulse steroids are more efficacious and safer than the standard treatment with oral corticosteroids.

Objective: This study is intended to compare the outcome of intralesional bleomycin with dexamethasone versus the bleomycin alone in infantile haemangioma. Materials and Methods: This RCT was performed after the ethical approval at the pediatric surgery department of KEMU/Mayo hospital Lahore. 114 patients were enrolled in two groups A and B. Both groups contained 57 patients each. Group A was administered intralesional bleomycin with dexamethasone and group B was given intralesional bleomycin alone with a space of 4 weeks. Selection of patients was made according to inclusions and exclusion criteria.

Bevacizumab Therapy for brain arteriovenous malformation that is not amenable to surgical intervention.

The CUSA (cavitron ultrasound surgical aspirator) is the method of choice for hepatic resection in our center. Recently a stapler-hepatectomy methods has been developed and approved for liver surgery using Covidien Endo-Gia stapler. The potential benefit of this method is a potential shorter transection time compared to the CUSA technique. Thus the investigators will perform a randomized controlled trial including 20 patients in the stapler-group and 20 patients in the CUSA control group. Primary endpoint will be transection speed. Secondary endpoints will be peri-operative (d-1, d0, d1, d3) cytokines concentration, T cell subsets, blood loss, morbidity, and a cost analysis.

Cerebral cavernous malformations (CCMs) are clusters of abnormal blood vessels in the brain and spine. CCMs can bleed and cause strokes, seizures, and headaches. In some patients, CCMs affect the blood brain barrier (BBB). The BBB is the body's separation of blood and its contents in the brain from the brain tissue itself. Abnormal leakiness or permeability of this barrier can cause disease. We will measure the permeability (leakiness) of the BBB using a magnetic resonance imaging (MRI) technique called dynamic contrast-enhanced MRI (DCEMRI). The purpose of this study is to look at whether statin medications change the permeability (leakiness) of the blood brain barrier in CCM patients. Statin medications are used to lower cholesterol levels and prevent heart attack and stroke. In addition, this medication may decrease the risk of brain hemorrhage or bleeding in patients with CCM. This study will examine whether the permeability of the BBB changes following the administration of simvastatin for three months.
