An MRCP scan is a scan that uses magnetic resonance imaging (MRI) to produce pictures of the liver, bile ducts, gallbladder and pancreas. Note: the information below is a general guide only. The arrangements,and the way tests are performed, may vary between different hospitals.
The goal of COPD management is to improve a patient’s functional status and quality of life by preserving optimal lung function, improving symptoms, and preventing the recurrence of exacerbations. Currently, no treatments aside from lung transplantation have been shown to significantly improve lung function or decrease mortality; however, oxygen therapy (when appropriate) and smoking cessation may reduce mortality. Once the diagnosis of COPD is established, it is important to educate the patient about the disease and to encourage his or her active participation in therapy.

Vertigo is a sense of rotation, rocking, or the world spinning, experienced even when someone is perfectly still. Many children attempt to create a sense of vertigo by spinning around for a time; this type of induced vertigo lasts for a few moments and then disappears. In comparison, when vertigo occurs spontaneously or as a result of an injury it tends to last for many hours or even days before resolving.
Many people report that inversion table therapy is a great way to stretch muscles and ligaments, reduce muscle spasms, and improve circulation. Stretching stimulates the lymph glands to increase the flow of lymphatic fluids; part of the body's waste disposal system. Similarly, cellular health depends on good blood circulation to deliver nourishment and remove waste. Inversion table therapy also helps to relieve motion sickness and stress. In addition, the body becomes more aware of its spatial orientation and balance when the inner ear is stimulated during inversion. Plus, it is not necessary for the body to be positioned completely upside down to gain benefits from inversion therapy! Unlike antigravity boots used with an inversion rack, an adjustable inversion table offers the flexibility to choose the most comfortable angle. Dialogue with Your Doctor Like anything that can affect your health, talk to your doctor before you start using an inversion table. This is important because certain medications and health conditions may make using an inversion table unsafe. Your doctor may recommend against inversion table therapy if you have obesity, a detached retina, fracture, glaucoma, heart condition (circulatory problem), hernia, implanted device, middle ear or eye infection, osteoporosis, are pregnant, or have a spinal injury. There may be other medical conditions not listed that your doctor may view as a contraindication.
The heart weighs between 7 and 15 ounces (200 to 425 grams) and is a little larger than the size of your fist. By the end of a long life, a person's heart may have beat (expanded and contracted) more than 3.5 billion times. In fact, each day, the average heart beats 100,000 times, pumping about 2,000 gallons. Your heart is located between your lungs in the middle of your chest, behind and slightly to the left of your breastbone (sternum). A double-layered membrane called the pericardium surrounds your heart like a sac. The outer layer of the pericardium surrounds the roots of your heart's major blood vessels and is attached by ligaments to your spinal column, diaphragm, and other parts of your body. The inner layer of the pericardium is attached to the heart muscle. A coating of fluid separates the two layers of membrane, letting the heart move as it beats. Your heart has 4 chambers. The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart. The left ventricle's chamber walls are only about a half-inch thick, but they have enough force to push blood through the aortic valve and into your body.
Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment
What are the classifications of burns? Burns are classified as first-, second-, or third-degree, depending on how deep and severe they penetrate the skin's surface. First-degree (superficial) burns. First-degree burns affect only the epidermis, or outer layer of skin. The burn site is red, painful, dry, and with no blisters. Mild sunburn is an example. Long-term tissue damage is rare and usually consists of an increase or decrease in the skin color. Second-degree (partial thickness) burns. Second-degree burns involve the epidermis and part of the dermis layer of skin. The burn site appears red, blistered, and may be swollen and painful. Third-degree (full thickness) burns. Third-degree burns destroy the epidermis and dermis and may go into the subcutaneous tissue. The burn site may appear white or charred Fourth degree burns. Fourth degree burns also damage the underlying bones, muscles, and tendons. There is no sensation in the area since the nerve endings are destroyed.
The best sleep position during pregnancy is “SOS” (sleep on side). Even better is to sleep on your left side. Sleeping on your left side will increase the amount of blood and nutrients that reach the placenta and your baby. Keep your legs and knees bent, and put a pillow between your legs.
A sleep disorder, or somnipathy, is a medical disorder of the sleep patterns of a person or animal. Some sleep disorders are serious enough to interfere with normal physical, mental, social and emotional functioning. Polysomnography and actigraphy are tests commonly ordered for some sleep disorders.
Waterhouse–Friderichsen syndrome (WFS), hemorrhagic adrenalitis or fulminant meningococcemia is defined as adrenal gland failure due to bleeding into the adrenal glands, commonly caused by severe bacterial infection: Typically the pathogen is the meningococcus Neisseria meningitidis.
If you use condoms perfectly every single time you have sex, they’re 98% effective at preventing pregnancy. But people aren’t perfect, so in real life condoms are about 85% effective — that means about 15 out of 100 people who use condoms as their only birth control method will get pregnant each year.
Hypothyroidism during pregnancy is treated with synthetic thyroid hormone, thyroxine (T4). Postpartum thyroiditis—inflammation of the thyroid gland—causes a brief period of hyperthyroidism, often followed by hypothyroidism that usually goes away within a year. Sometimes the hypothyroidism is permanent.
Colon polyp facts Colon polyps are growths on the inner lining of the colon and are very common. Colon polyps are important because they may be, or may become malignant (cancerous). They also are important because based on their size, number, and microscopic anatomy (histology); they can predict which patients are more likely to develop more polyps and colon cancer. Changes in the genetic material of cells lining the colon are the cause of polyps. There are different types of colon polyps with differing tendencies to become malignant and abilities to predict the development of more polyps and cancer. It is important to recognize families with members who have familial genetic conditions causing polyps because some of these conditions are associated with a very high incidence of colon cancer, and the cancer can be prevented or discovered early.
