Capillary Malformation-Arteriovenous Malformation

Background:
RASopathies are a group of conditions caused by a genetic change. People with a RASopathy may have developmental issues, cognitive disability, poor growth, and birth defects. They may also have an increased risk for developing cancer. Researchers want to learn more.
Objective: To learn more about RASopathies, how genes and environmental factors contribute to cancer development in people with RASopathies, and the best way to find these cancers and other conditions early or prevent them.
Eligibility:
People of any age who have or may have a RASopathy, and their family members.
Design:
Participants will complete questionnaires about their personal and family medical history. Their medical records will be reviewed.
Participants will give blood and urine samples. They will give a saliva or cheek cell sample. Some samples will be used for genetic testing.
Participants may have a skin biopsy.
Participants may have a physical exam by the RASopathies study team. They may also have exams by additional specialists, such as dentists; urologists; ear, nose, and throat doctors; and neurologists.
Participants may have computed tomography of the face and mouth. They may have an ultrasound of the abdomen. They may have a bone density scan. They may have skeletal and/or spine x-rays. They may have magnetic resonance imaging of the brain, low back, chest, and/or heart. They may be photographed.
Participants may have other tests, such as sleep, brain and heart electrical activity, speech and swallow, metabolism, hearing, eye, and colon function tests.
Participants may sign separate consent forms for some tests.
Participation will last indefinitely. Participants may be contacted once in a while by phone or mail. They may have follow-up visits.

Laser treatment (LT) is the first-line treatment for Vascular Pathology. However even when LT is based on the selective photothermolysis it causes the first-degree burns. While being typically benign by affecting only the epidermis, or outer layer of skin, the burn site is remaining red, dry, and very painful. As Haemoblock contains nanoparticles of silver and is known for both bactericidal and bacteriostatic effects, it likely decreases the potential for infection postoperatively. Furthermore, after fibrin replaces the superficial structure "Hemoblock-albumin", the polyacrylate matrix is plasmolyzed which initiates the cascade of signals required for the tissue regeneration processes. Objective of the study was to examine the effect of the Regenerative Solution "Hemoblock" in lowering postoperative complications in children diagnosed with Vascular Pathology undergoing a laser surgery if delivered with transdermal patches.
