Active clinical trials for "Hemangioma"

Uterine arteriovenous malformations (UAVM) are short circuits between systemic arterial and venous networks within the uterus. They are congenital or acquired (in the course of an endo-uterine gesture such as curettage or interventions such as caesareans or myomectomies). They can be manifested by severe metrorrhagia that can go as far as to put the patient's vital prognosis at risk. There are no recommendations for the management of UAVM since this pathology is rare and therefore series are performed with few cases. If some of these UAVM disappear spontaneously after a therapeutic abstention, when the clinical context allows it, in case of symptomatic UAVM, a selective embolization with arteriography is often carried out to postpone the hysterectomy of hemostasis. There are also more marginal management options such as Gonadotropin-Releasing Hormone agonists, methotrexate or curettage that are decided on a case by case basis depending on the symptoms and protocols of each medical team. Regarding subsequent fertility and pregnancy outcomes after conservative treatment, the number of studies is even lower.

Infantile hemangioma is a benign tumor belonging to the group of vascular tumors in the ISSVA classification (International Society for the Study of Vascular Anomalies). The diagnosis is clinical and radiological. The hemangioma appears during the first weeks of life (70% classically within 2 weeks after birth) but can, when it develops in the subcutaneous tissue, appear until the age of 2 to 3 months . Its evolution is characteristic and is divided into 3 phases with a proliferative phase characterized by a rapid increase in the size of the tumor (up to 6 to 12 months), a phase of stabilization (from 12 to 36 months) with a stopping of the growth of the hemangioma and a regression of its size and a phase of involution with the disappearance of the lesion which may give way to residual fibroadipose tissue, cutaneous telangiectases, scars … The usual complications of haemangiomas occur during the proliferative phase. It is necrosis, ulcerations that can be complicated by bleeding or infection and eventually indelible scarring. Other complications related to the site of development of hemangiomas (amblyopia, astigmatism, upper respiratory obstruction, nasal obstruction, sphincter disorders, eating disorders), hemangiomas destroying structures noble (breast hypodévelopment, alopecia). The aesthetic prognosis can be seriously compromised for facial locations. Historically, when drug therapy was required, patient management was based on systemic corticosteroids (at doses of 3 to 5 mg / kg / day) in first-line therapy and vincristine as a second-line failure of corticosteroid therapy or when life-threatening is at stake. In 2014, the high French health authority (HAS) gave Marketing Authorization for Hemangiol 3.75 mg / ml oral solution for the management of infantile proliferative hemangioma requiring first-line systemic treatment, evaluating the actual benefit as important. The selected indication concerns children from 5 weeks to 5 months with: Hemangiomas leading to a vital or functional risk, Hemangiomas ulcerated painful and / or not responding to simple care, Hemangiomas with a risk of permanent scarring or disfigurement. The 2014 HAS Transparency Commission wishes in its report "to have follow-up data of prescriptions allowing to describe on a representative sample of patients, the characteristics of the treated patients, the indication, the doses and the durations of treatment of this specialty ". The objective of our study is to describe the use of Hemangiol in current practice in our hospital from 2014 to 2018.

Propranolol use for infancy hemangiomas is of world wide interest due to low cost and presumed efficacy. The investigators hypothesized that the drug ist highly active against growing hemangiomas in problematic sites and that there are little side effects. This observational study was undertaken in an uncontrolled fashion to determine sample size, design and and tools for a later randomized controlled trial on propranolol versus physical therapy (i.e.cryotherapy) which is the most prevalent treatment for the condition. During this initial series side effects and relevant design aspects became evident which warrant expedited reporting.

This is an open-label whole-body PET/CT study for investigation of radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and diagnostic performance of 68Ga-NEB in healthy volunteers and patients with suspected infection. Changes of routine blood and urine tests and any adverse events will be collected from the volunteers. Adverse events will also be observed in the patients.

A combined set of quantitative skin imaging methods will quantitatively describe the natural ontogeny and the response to standard treatments over time in patients with infantile hemangiomas.

The investigators hypothesize that there are differences between infantile hemangiomas (IH) during the proliferating and involuting phases and in response to medical treatment that can be detected by optical tomography of these hemangiomas.

Controversy exists in the treatment of airway hemangiomas ranging from tracheotomy, various lasers, to open removal, none of which have proven to be a gold standard. Venous malformations of the airway are difficult to treat and also require laser therapy or open removal and often repeated treatments are required. Similarly airway lymphatic malformations can require multiple treatment modalities as well as multiple procedures and are infrequently eradicated when extensive. New uses for various lasers and differing treatment protocols are frequently developed. Review of the treatment modalities and efficacy of these methods is required. The goal of this research is to determine protocols for treatment of airway vascular malformation and to evaluate our results from treatment of these lesions.

The goal of this study is to clarify the degree of immune suppression in infants requiring therapy and to create guidelines for evaluation and prevention of infection in infants on oral steroids for hemangiomas.

Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).

PURPOSE The purpose of this study is to learn more about multifocal lymphangioendotheliomatosis with thrombocytopenia (MLT). MLT is a rare vascular disorder characterized by multiple congenital skin and visceral lesions, profound thrombocytopenia, and gastrointestinal bleeding. The skin lesions may appear red, brown or blue, often misdiagnosed as hemangiomas. The gastrointestinal tract, liver, and lungs are the most common internal organs involved. The severe thrombocytopenia (low platelets) is believed to be the result of platelet trapping within the skin and visceral vascular lesions. Severe and chronic gastrointestinal bleeding is common during infancy and early childhood. Although a relatively newly described entity, MLT was likely previously reported as hemangiomas, blue rubber bleb nevus syndrome, diffuse hemangiomatosis, Kasabach-Merritt phenomenon, and hereditary hemorrhagic telangiectasia. The term cutaneovisceral angiomatosis with thrombocytopenia is also a term used for this same disease. This study is a longitudinal cohort study of MLT to collect detailed clinical data on the distribution of disease, disease severity, and complications. This data will be used to create diagnostic criteria and an evaluation protocol for infants with this disease
