Sodium levels are tightly controlled in a healthy individual by regulation of urine concentration and an intact thirst mechanism. Hypernatremia (defined as a serum sodium level >145 mEq/L) is rare in patients with preserved thirst mechanism. When hypernatremia does occur, it is associated with a high mortality rate (>50% in most studies). Given this high mortality rate, the emergency physician must be able to recognize and treat this condition. This article discusses the patients in whom hypernatremia should be suspected and how to initiate workup and administer appropriate treatment. In general, hypernatremia can be caused by derangement of the thirst response or altered behavioral response thereto (primarily psychiatric patients, and elderly patients who are institutionalized), impaired renal concentrating mechanism (diabetes insipidus [DI]) secondary to kidney pathology (nephrogenic DI) or difficulty with the neurohormonal control of this concentrating mechanism (central DI), or by losses of free water from other sources.

Breast cancer usually starts off in the inner lining of milk ducts or the lobules that supply them with milk. A malignant tumor can spread to other parts of the body. A breast cancer that started off in the lobules is known as lobular carcinoma, while one that developed from the ducts is called ductal carcinoma. The vast majority of breast cancer cases occur in females. This article focuses on breast cancer in women. We also have an article about male breast cancer. Breast cancer is the most common invasive cancer in females worldwide. It accounts for 16% of all female cancers and 22.9% of invasive cancers in women. 18.2% of all cancer deaths worldwide, including both males and females, are from breast cancer. Breast cancer rates are much higher in developed nations compared to developing ones. There are several reasons for this, with possibly life-expectancy being one of the key factors - breast cancer is more common in elderly women; women in the richest countries live much longer than those in the poorest nations. The different lifestyles and eating habits of females in rich and poor countries are also contributory factors, experts believe. According to the National Cancer Institute, 232,340 female breast cancers and 2,240 male breast cancers are reported in the USA each year, as well as about 39,620 deaths caused by the disease.

The Blood Flow In Leg

Cystinuria is a condition characterized by the buildup of the amino acid cystine, a building block of most proteins, in the kidneys and bladder. As the kidneys filter blood to create urine, cystine is normally absorbed back into the bloodstream. People with cystinuria cannot properly reabsorb cystine into their bloodstream, so the amino acid accumulates in their urine. As urine becomes more concentrated in the kidneys, the excess cystine forms crystals. Larger crystals become stones that may lodge in the kidneys or in the bladder. Sometimes cystine crystals combine with calcium molecules in the kidneys to form large stones. These crystals and stones can create blockages in the urinary tract and reduce the ability of the kidneys to eliminate waste through urine. The stones also provide sites where bacteria may cause infections.

Most times, a pulmonary embolism is caused by blood clots that travel from the legs or, rarely, other parts of the body (deep vein thrombosis, or DVT). Symptoms include shortness of breath, chest pain, and cough. Prompt treatment to break up the clot greatly reduces the risk of death. This can be done with blood thinners and drugs or procedures. Compression stockings and physical activity can help prevent clots from forming in the first place.

Comas are caused by an injury to the brain. Brain injury can be due to increased pressure, bleeding, loss of oxygen, or buildup of toxins. The injury can be temporary and reversible. It also can be permanent.

A hematoma is a common complication of surgical procedures. A large, expanding hematoma can result in necrosis of the overlying skin (1,2) or adjacent subcutaneous fat, increased incidence of infection, scarring, skin hyperpigmentation, tissue edema and a prolonged convalescence.

In multiple sclerosis, the immune system attacks the protective sheath called myelin, that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause the nerves to deteriorate or become damaged.

How To Improve Memory Power, How To Improve Concentration And Memory, Foods That Help The Brain---- http://brain-revitalizer.info-pro.co --- Brain Entrainment, For centuries humans have wondered at the connection between specific sound frequencies and the effect it can have on the brain and corresponding moods and emotions. From tribal drums to periodic stimulus tones the human brain taps into dominant external frequencies and when it does the mind can be altered to induce a host of different states including relaxation, sleep, creativity and excitement. The practice of causing brainwave frequencies to match a periodic stimulus to produce an intended state is called brainwave entrainment or brainwave synchronization and it is becoming more popular as life becomes more stressful. The study of sound and light and how it affects the human brain is nothing new. In the 1930's William Grey Walter used EEG equipment and strobe lights to detect the existence of high speed alpha waves and low speed delta waves and how each played a factor in human sleep patterns. In 1973 Gerald Oster published his discovery of binaural beats in Scientific American, a breakthrough article that defined binaural beats as apparent sounds which arise in the brain for specific physical stimuli. Though first discovered in 1839 by Heinrich Wilhelm Dove it wasn't until Oster's research that scientists began to speculate that binaural beats could be used to help induce relaxation, creativity and other desirable mental states. Today brainwave entrainment is gaining rapid popularity with people who feel over-stressed, depressed and unmotivated. With technology growing by leaps and bounds it's not hard to understand how a person can feel overwhelmed by information and sensory overload and instead of taking pills a growing segment of the population is turning to brainwave entrainment to produce a more natural and lasting feeling of relaxation. But YOU can be different! You can use Genius Brain Power to empower your brain so that you come alive with more energy, learn quicker, think more creatively, focus on your work like never before and drastically reduce stress with amazingly deep states of relaxation and meditation. click here: http://brain-revitalizer.info-pro.co

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.
