Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.

The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.

CPAP is a treatment that uses mild air pressure to keep your breathing airways open. It involves using a CPAP machine that includes a mask or other device that fits over your nose or your nose and mouth, straps to position the mask, a tube that connects the mask to the machineโ€™s motor, and a motor that blows air into the tube. CPAP is used to treat sleep-related breathing disorders including sleep apnea. It also may be used to treat preterm infants who have underdeveloped lungs.

The first operation is harvesting the heart from the donor. The donor is usually an unfortunate person who has suffered irreversible brain injury, called "brain death". Very often these are patients who have had major trauma to the head, for example, in an automobile accident. The victim's organs, other than the brain, are working well with the help of medications and other "life support" that may include a respirator or other devices. A team of physicians, nurses, and technicians goes to the hospital of the donor to remove donated organs once brain death of the donor has been determined. The removed organs are transported on ice to keep them alive until they can be implanted. For the heart, this is optimally less than six hours. So, the organs are often flown by airplane or helicopter to the recipient's hospital.

Most people with TS are not significantly impaired by their symptoms and therefore do not require treatment with medication. However, several medications are available to control TS symptoms that interfere with functioning. Except in more severe cases when tics are sometimes painful, the main reasons for medication are to improve appearance and lessen embarrassing social interactions. As with all medications, there are possible side effects that should be monitored carefully by the physician. Patients should always be included in the decision to take medication, as they are the best judge of how disruptive the symptoms are to them. Early diagnosis and treatment are crucial to help the person with TS cope with his or her condition. Often, people make fun of a person with TS. Parents of children with TS also may find it difficult to cope with their child's behavior. When people with TS are diagnosed correctly and treated for the condition early, they can learn to cope with their disorder and accept that they are ok and normal.

Gallbladder cancer is cancer that begins in the gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder stores bile, a digestive fluid produced by your liver. Gallbladder cancer is uncommon. When gallbladder cancer is discovered at its earliest stages, the chance for a cure is very good. But most gallbladder cancers are discovered at a late stage, when the prognosis is often very poor. Gallbladder cancer is difficult to diagnose because it often causes no specific signs or symptoms. Also, the relatively hidden nature of the gallbladder makes it easier for gallbladder cancer to grow without being detected.

Has your dentist or endodontist told you that you need root canal treatment? If so, you're not alone. Millions of teeth are treated and saved each year with root canal, or endodontic, treatment. Remember, root canal treatment doesn't cause pain, it relieves it. Watch our videos below to learn more! Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development. In a fully developed tooth, the tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.

Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate (failure to thrive). The affected children develop normally until around age 1 year when they experience a progressive loss of mental abilities and movement (psychomotor regression). Children with Niemann-Pick disease type A also develop widespread lung damage (interstitial lung disease) that can cause recurrent lung infections and eventually lead to respiratory failure. All affected children have an eye abnormality called a cherry-red spot, which can be identified with an eye examination. Children with Niemann-Pick disease type A generally do not survive past early childhood.
