Retinoblastoma is an eye cancer that begins in the retina — the sensitive lining on the inside of your eye. Retinoblastoma most commonly affects young children, but can rarely occur in adults. Your retina is made up of nerve tissue that senses light as it comes through the front of your eye. The retina sends signals through your optic nerve to your brain, where these signals are interpreted as images. A rare form of eye cancer, retinoblastoma is the most common form of cancer affecting the eye in children. Retinoblastoma may occur in one or both eyes.
Pleurisy is a condition in which the pleura — a membrane consisting of a layer of tissue that lines the inner side of the chest cavity and a layer of tissue that surrounds the lungs — becomes inflamed. Also called pleuritis, pleurisy causes sharp chest pain (pleuritic pain) that worsens during breathing. A variety of underlying conditions can cause pleurisy. Treatment of pleurisy involves pain control and treating the underlying condition.
Retinitis pigmentosa is a rare, inherited degenerative eye disease that causes severe vision impairment. Symptoms often begin in childhood. They include decreased vision at night or in low light and loss of side vision (tunnel vision).
We are aware that the "official" way to use an ear candle is small end down into the ear, but for this video, we have elected to use it the way most "lay" public would (small end up). Ear candling is an alternative medicine practice that is thought to remove earwax. However, this video illustrates how ineffective this practice is in removing earwax... and can potentially be even harmful. And yes... It is still frequently practiced.
Giant cell tumors of the tendon sheath are common lesions and are the second most frequent tumors in the hand, after synovial cysts. They are diagnosed by means of clinical examination and complementary examinations (simple radiography and magnetic resonance). Erosion and invasion of the phalangeal bone affected may be seen on radiological examination. Magnetic resonance may show a “fluorescent or radiant effect” may be observed, caused by the high quantity of hemosiderin inside the tumor. Surgical treatment is the commonest practice, and complete excision is important for avoiding recurrence of the tumor, especially when bone invasion is observed on imaging examinations, which is generally related to greater tumor recurrence. In this paper, a case of a giant cell tumor of the tendon sheath in the middle phalanx of the third finger of a 45-year-old female patient is presented. This was successfully treated by means of surgery using a double access approach (dorsal and volar)
Expand Section. Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs.
An estimated 20 million LASIK procedures have been performed since 1998. The FDA website is filled with stories of complications, including pain, dizziness and detached retinas. CBS2's Chris Wragge reports.
A carotid endarterectomy is performed in a sterile surgical suite or standard operating room. You may go home the same day or stay 1–2 nights after the procedure depending on your medical condition. You receive a local anesthetic or general anesthesia. Your vascular surgeon makes an incision at the front of your neck. After removing the plaque from the artery your vascular surgeon repairs the artery by stitching in a natural graft (formed from a piece of vein from elsewhere in your body) or a woven patch. The incision is closed
What is a brain aneurysm? A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result.
This procedure describes one of the most versatile approaches to the anterior skull base for large tumors of the sinonasal cavity. It may be used with or without a craniofacial resection. The benefits of this approach are: wide access around the tumor; good postoperative cosmesis; & decreased operative & postoperative morbidity. We have used this approach for many bilateral tumors of the nasal & sinus cavities that approach &/or invade the skull base & brain. This video show the resection of a large esthesioneuroblastoma.
Symptoms Burning stomach pain Feeling of fullness, bloating or belching Fatty food intolerance Heartburn Nausea The most common peptic ulcer symptom is burning stomach pain. Stomach acid makes the pain worse, as does having an empty stomach. The pain can often be relieved by eating certain foods that buffer stomach acid or by taking an acid-reducing medication, but then it may come back. The pain may be worse between meals and at night. Nearly three-quarters of people with peptic ulcers don't have symptoms. Less often, ulcers may cause severe signs or symptoms such as: Vomiting or vomiting blood — which may appear red or black Dark blood in stools, or stools that are black or tarry Trouble breathing Feeling faint Nausea or vomiting Unexplained weight loss Appetite changes
Coarctation of the aorta (CoA[1][2] or CoAo), also called aortic narrowing, is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word “coarctation” means narrowing. Coarctations are most common in the aortic arch. The arch may be small in babies with coarctations. Other heart defects may also occur when coarctation is present, typically occurring on the left side of the heart. When a patient has a coarctation, the left ventricle has to work harder. Since the aorta is narrowed, the left ventricle must generate a much higher pressure than normal in order to force enough blood through the aorta to deliver blood to the lower part of the body. If the narrowing is severe enough, the left ventricle may not be strong enough to push blood through the coarctation, thus resulting in lack of blood to the lower half of the body. Physiologically its complete form is manifested as interrupted aortic arch
