Skin changes are among the most visible signs of aging. Evidence of increasing age includes wrinkles and sagging skin. Whitening or graying of the hair is another obvious sign of aging. Your skin does many things. It: Contains nerve receptors that allow you to feel touch, pain, and pressure Helps control fluid and electrolyte balance Helps control your body temperature Protects you from the environment Although skin has many layers, it can generally be divided into three main parts: The outer part (epidermis) contains skin cells, pigment, and proteins. The middle part (dermis) contains blood vessels, nerves, hair follicles, and oil glands. The dermis provides nutrients to the epidermis. The inner layer under the dermis (the subcutaneous layer) contains sweat glands, some hair follicles, blood vessels, and fat. Each layer also contains connective tissue with collagen fibers to give support and elastin fibers to provide flexibility and strength.
Fainting occurs when the blood supply to your brain is momentarily inadequate, causing you to lose consciousness. This loss of consciousness is usually brief. Fainting can have no medical significance, or the cause can be a serious disorder. Therefore, treat loss of consciousness as a medical emergency until the signs and symptoms are relieved and the cause is known. Discuss recurrent fainting spells with your doctor. If you feel faint Lie down or sit down. To reduce the chance of fainting again, don't get up too quickly. Place your head between your knees if you sit down. If someone else faints Position the person on his or her back. If the person is breathing, restore blood flow to the brain by raising the person's legs above heart level — about 12 inches (30 centimeters) — if possible. Loosen belts, collars or other constrictive clothing. To reduce the chance of fainting again, don't get the person up too quickly. If the person doesn't regain consciousness within one minute, call 911 or your local emergency number. Check the person's airway to be sure it's clear. Watch for vomiting. Check for signs of circulation (breathing, coughing or movement). If absent, begin CPR. Call 911 or your local emergency number. Continue CPR until help arrives or the person responds and begins to breathe.
Patent ductus arteriosus (PDA), in which there is a persistent communication between the descending thoracic aorta and the pulmonary artery that results from failure of normal physiologic closure of the fetal ductus (see image below), is one of the more common congenital heart defects.
Bone pain: Pain is the most common sign of bone cancer, and may become more noticeable as the tumor grows. Bone pain can cause a dull or deep ache in a bone or bone region (e.g., back, pelvis, legs, ribs, arms). Early on, the pain may only occur at night, or when you are active.
Heartburn is a burning pain in your chest, just behind your breastbone. The pain is often worse when lying down or bending over. Occasional heartburn is common and no cause for alarm. Most people can manage the discomfort of heartburn on their own with lifestyle changes and over-the-counter medications. Heartburn that is more frequent or interferes with your daily routine may be a symptom of a more serious condition that requires medical care

Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The most common symptoms of medulloblastoma include behavioral changes, changes in appetite, symptoms of increased pressure on the brain (eg, headache, nausea, vomiting, and drowsiness, as well as problems with coordination). Unusual eye movements may also occur. Like many tumor types, the exact cause of medulloblastoma is not known. However, scientists are making significant strides in understanding its biology. Changes have been identified in genes and chromosomes (the cell’s DNA blueprints) that may play a role in the development of this tumor. There are also a few rare, genetic health syndromes that are associated with increased risk for developing this tumor.
Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy the entire larynx is removed and in a partial laryngectomy only a portion is taken out. The laryngectomee breathes through an opening in the neck known as a stoma.
The most frequent incision utilized to open the abdomen for liver surgery is called a chevron incision. In this incision a cut is made on the abdomen below the rib cage. The cut starts under the armpit below the ribs on the right side of the abdomen and continues all the way across the abdomen to the opposite arm pit thereby the whole width of the abdomen is cut to provide access to the liver. The average length of the incision is approximately 24 to 30 inches. This is one of the longest incisions is utilized in abdominal surgery. The incision is frequently associated with significant discomfort after the surgery and in some patients the discomfort can continue for many months, particularly when some of the nerves in the abdominal wall have been cut during the surgery. Laparoscopic surgery provides advantages over open surgery for the liver since the chevron incision is completely avoided and the surgery is performed through tiny incisions. As a consequence the duration of stay in hospital, the amount and duration of post operative discomfort, and the length of recovery is much shorter after the laparoscopic procedure compared to open surgery

Trabeculectomy, also called Filtration Surgery, is a surgical procedure performed for treatment of glaucoma. The treatment involves removing part of the trabecular meshwork and creating a new escape route for the aqueous humor. When successful, it allows the aqueous fluid to drain from the eye into an area underneath the conjunctiva where it is subsequently absorbed by the body's circulatory system or filtered into tears.
In this procedure:
- A conjunctival pocket is created and maybe treated with Mitomycin or other antimetabolites for a few minutes. These drugs are used to prevent scarring of the operation site. Scarring, if occurs, may clog the new drainage canal, and is therefore the major reason the procedure may fail.
- A half thickness flap is then made in the sclera and is dissected all the way to the clear cornea.
- A block of scleral tissue including part of the trabecular meshwork and Schlemm's canal is then removed to make a hole into the anterior chamber of the eye.
- As the iris may plug up this hole from the inside, a piece of the iris maybe removed at this time. This is called iridectomy.
- The scleral flap is then sutured loosely back in place. These sutures can be released gradually during a couple of weeks after surgery. This allows adjustment of the aqueous flow in order to achieve target pressure and to avoid the complication of having a too low intraocular pressure.
- The conjunctiva is sewn back in place to cover the area.
After surgery, aqueous humor drains into a filtering area called a "bleb" under the conjunctiva. Since the surgery is usually performed near the top of the eye, the bleb can easily be concealed behind the upper eyelid.
