Cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. The liver carries out several necessary functions, including detoxifying harmful substances in your body, cleaning your blood and making vital nutrients. Cirrhosis occurs in response to damage to your liver. Each time your liver is injured, it tries to repair itself. In the process, scar tissue forms. As cirrhosis progresses, more and more scar tissue forms, making it difficult for the liver to function. Decompensated cirrhosis is the term used to describe the development of specific complications resulting from the changes brought on by cirrhosis. Decompensated cirrhosis is life-threatening. The liver damage done by cirrhosis generally can't be undone. But if liver cirrhosis is diagnosed early and the cause is treated, further damage can be limited and, rarely, reversed.
A simple test of fingernail clippings could replace a blood draw as a way to diagnose and monitor type 2 diabetes mellitus (T2DM), with huge implications for tracking the disease in the developing world. Research on this method by a team of Belgian researchers was reported July 28, 2015, at the 2015 American Association for Clinical Chemistry (AACC) Annual Meeting and Clinical Lab Expo in Atlanta. The team, led by Joris R. Delanghe, MD, PhD, of the Department of Global Chemistry, Microbiology and Immunology at Ghent University, collected nail clippings from 25 people with T2DM and 25 without the disease. The clippings were ground into a powder and tested with an inexpensive FT-IR photometer to measure how much the protein in the nails had bonded with sugar molecules, a process known as glycation. “We found a striking difference in the measurements between the control group and the patients with diabetes,” Delanghe said. In an interview with Evidence-Based Diabetes Management, he said replacing the standard blood test to measure glycated hemoglobin is a huge advantage. In many cultures, he said, “Taking blood is something that cannot be tolerated.” - See more at: http://www.ajmc.com/journals/evidence-based-diabetes-management/2015/september-2015/fingernail-tests-may-offer-cheap-simple-way-to-diagnose-diabetes#sthash.XQxnBcNO.dpuf
With inner ear disorders, your brain receives signals from the inner ear that aren't consistent with what your eyes and sensory nerves are receiving. Vertigo is what results as your brain works to sort out the confusion. These self-help acupressure points works with meridians to help the body regain normal healing and homeostasis.
Osteomyelitis is an infection in a bone. Infections can reach a bone by traveling through the bloodstream or spreading from nearby tissue. Infections can also begin in the bone itself if an injury exposes the bone to germs. In children, osteomyelitis most commonly affects the long bones of the legs and upper arms. Adults are more likely to develop osteomyelitis in the bones that make up the spine (vertebrae). People who have diabetes may develop osteomyelitis in their feet if they have foot ulcers. Once considered an incurable condition, osteomyelitis can be successfully treated today. Most people require surgery to remove parts of the bone that have died — followed by strong antibiotics, often delivered intravenously, typically for at least four to six weeks.
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.
A tracheoesophageal fistula (TEF, or TOF; see spelling differences) is an abnormal connection (fistula) between the esophagus and the trachea. TEF is a common congenital abnormality, but when occurring late in life is usually the sequela of surgical procedures such as a laryngectomy.
To remove a smaller stone in your ureter or kidney, your doctor may pass a thin lighted tube (ureteroscope) equipped with a camera through your urethra and bladder to your ureter. Once the stone is located, special tools can snare the stone or break it into pieces that will pass in your urine.
The cat's stomach is a sac-like structure designed to store large volumes of food and continue the digestive process. The esophagus carries food to the stomach, where it enters via a valve-like structure called the cardiac sphincter. On the interior surface of the stomach is a series of folds called gastric folds. These folds function to help grind and digest food. The inner stomach lining secretes acids and enzymes to break down food. Once the initial stomach digestive process is complete, the partially digested food exits the stomach through the pyloric sphincter area and then enters the duodenum (first segment of the small intestine). Once eaten, most food leaves the stomach within twelve hours after entering.
If you have multiple sclerosis (MS), you probably had several tests done before you received your diagnosis. There isn’t one test to diagnosis MS, so testing can vary. Doctors can use neurological exams, information about previous symptoms, blood tests, and spinal fluid tests. A magnetic resonance imaging (MRI) scan isn’t used to diagnose MS but rather to rule out other diseases. A diagnosis of MS requires more information than what a scan alone can give. By looking at more than one test or exam result, doctors can get a clearer picture of what’s going on in your body.
The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.
The average human digestive tract is home to as many as 1,000 species of microorganisms. Most of them are harmless -- or even helpful -- under normal circumstances. But when something upsets the balance of these organisms in your gut, otherwise harmless bacteria can grow out of control and make you sick. One of the worst offenders is a bacterium called Clostridium difficile(C. difficile, or C. diff). As the bacteria overgrow they release toxins that attack the lining of the intestines, causing a condition called Clostridium difficilecolitis.
Learn about Bicuspid Aortic Valves in this presentation. Bicuspid Aortic Valves are present in about 2% of the population and are the most common congenital disorder. Find out more about a Bicuspid Aortic Valve by visiting the following link:
This syndrome was previously known as reflex sympathetic dystrophy, algodystrophy, causalgia, Sudeck atrophy, transient osteoporosis, and acute atrophy of bone. Usually occurring after an injury, CRPS presents with pain out of proportion to the injury, temperature change, edema, and abnormal skin color. Type I CRPS (90% of CRPS cases) occurs without a definable nerve lesion, while type II occurs with a definable nerve lesion. The pathogenesis is likely due to an injury causing increased sensitivity to sympathetic nerves, an abnormal response to and sensation of pain, and increased neuropeptide release causing burning pain to light touch (allodynia).
The pituitary is a small gland found inside the skull just below the brain and above the nasal passages, which are above the fleshy back part of the roof of the mouth (known as the soft palate). The pituitary sits in a tiny bony space called the sella turcica. The nerves that connect the eyes to the brain, called the optic nerves, pass close by it.
