Myelomeningocele remains the most complex congenital malformation of the central nervous system that is compatible with life. This lesion results when the neural tube fails to fold normally during postovulatory Days 21 to 27.[6] The exact cause of disorders remains under some historical debate and is not within the scope of this paper. Myelomeningocele within the context of this discussion refers only to lesions that involve an open caudal neural tube defect on the surface of the skin
EART (Health Education and Rescue Training) Wilderness First Aid is an intensive course that covers patient examination and evaluation, body systems and anatomy, wound care, splinting, environmental emergencies, and backcountry medicine. Hands-on simulations provide first-hand training in treating patients. This is an excellent course taught by experienced Wilderness First Responders and Emergency Medical Technicians and is highly recommended to all wilderness travelers. People who pass the courses will receive a Wilderness First Aid certification from the Emergency Care and Safety Institute (ECSI) which is good for 2 years. Participants who successfully pass CPR and HEART Wilderness First Aid will have met the First Aid requirements for OA Leader Training.
LASIK, which stands for laser in-situ keratomileusis, is a popular surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism. All laser vision correction surgeries work by reshaping the cornea, the clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. LASIK is one of a number of different surgical techniques used to reshape the cornea.

Overweight does not necessarily equal unhealthy. There are actually plenty of overweight people who are in excellent health (1). Conversely, many normal weight people have the metabolic problems associated with obesity (2). That’s because the fat under the skin is actually not that big of a problem (at least not from a health standpoint, it’s more of a cosmetic problem). It’s the fat in the abdominal cavity, the belly fat, that causes the biggest issues (3). If you have a lot of excess fat around your waistline, even if you’re not very heavy, then you should take some steps to get rid of it. Belly fat is usually estimated by measuring the circumference around your waist. This can easily be done at home with a simple tape measure. Anything above 40 inches (102 cm) in men and 35 inches (88 cm) in women, is known as abdominal obesity. There are actually a few proven strategies that have been shown to target the fat in the belly area more than other areas of the body.
Abdominal aortic aneurysms can weaken the aorta, your body’s largest blood vessel. This can develop into a potentially serious heath problem that can be fatal if the aneurysm bursts, causing massive internal bleeding. Endovascular stent grafting, or endovascular aneurysm repair (EVAR), is a newer form of treatment for abdominal aortic aneurysm that is less invasive than open surgery. Endovascular stent grafting uses an endovascular stent graft to reinforce the wall of the aorta and to help keep the damaged area from rupturing.
What is gestational trophoblastic disease? Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas of the body. To learn more about how cancers start and spread, see What Is Cancer? Gestational trophoblastic (jeh-STAY-shuh-nul troh-fuh-BLAS-tik) disease (GTD) is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus. GTD does not develop from cells of the uterus like cervical cancer or endometrial (uterine lining) cancer do. Instead, these tumors start in the cells that would normally develop into the placenta during pregnancy. (The term gestational refers to pregnancy.) GTD begins in the layer of cells called the trophoblast (troh-fuh-BLAST) that normally surrounds an embryo. (Tropho- means nutrition, and -blast means bud or early developmental cell.) Early in normal development, the cells of the trophoblast form tiny, finger-like projections known as villi. The villi grow into the lining of the uterus. In time, the trophoblast layer develops into the placenta, the organ that protects and nourishes the growing fetus.
Open heart (coronary artery bypass, or CABG) surgery is performed in order to reroute, or "bypass," blood around blocked arteries, thereby improving the supply of oxygen-rich blood to the heart. Surgeons usually use an artery from the chest wall to construct the "detour" around the blocked part of the artery. Veins from the legs are also used.
