Electronystagmography (ENG) is a diagnostic test to record involuntary movements of the eye caused by a condition known as nystagmus. It can also be used to diagnose the cause of vertigo, dizziness or balance dysfunction by testing the vestibular system.
A liver abscess is a pus-filled mass inside the liver. Common causes are abdominal infections such as appendicitis or diverticulitis due to haematogenous spread through the portal vein. A pyogenic liver abscess (PLA) is a pocket of pus that forms in the liver in response to an infection or trauma. Pus is a fluid composed of white blood cells, dead cells, and bacteria that forms when your body fights off infection.Dec 11, 2015
When you’re trying to conceive a baby it is worth giving anything a go which you think will boost your chances. This includes considering that there may be better positions for getting pregnant. But it pays to bear in mind that the human race has been around for over 200,000 years and most of us were probably conceived without our ancestors investing too much thought into the mechanics. Science has proven that successful conception isn’t so much about sexual position as the frequency of sex between a fertile couple. Basically, if you want to fall pregnant, don’t use contraception and have frequent, active and enjoyable sex. Importantly, don’t stress too much about whether you’re doing it the right way. Women can, and do, conceive in any position. Nature has a way of making sure of that.
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.
Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.
Thoracentesis is a procedure used to obtain a sample of fluid from the space around the lungs. Normally, only a thin layer of fluid is present in the area between the lungs and chest wall. However, some conditions can cause a large amount of fluid to accumulate. This collection of fluid is called a pleural effusion.
Cisplatin is in a class of drugs known as platinum-containing compounds used to treat various types of cancers including metastatic testicular and ovarian tumors. The molecule was first discovered in 1845, but did not receive FDA approval until 1978. Today it is known as the "penicillin of cancer drugs," because it is so effective for many different cancers. There are three key players involved in Cisplatin's mechanism: (1) Cisplatin, (2) DNA (3) and an HMG Protein. Most Cisplatin enters the body through active transport, but some molecules are passively defused through the cell membrane. Once in the nucleus, Cisplatin can form an adduct with two consecutive guanine bases within a strand of DNA. The molecule loses its chlorine atoms in exchange for the nitrogen atoms of the target guanines. Cisplatin can bond more tightly with nitrogen because nitrogen balances the platinum charge more effectively than chlorine. It is this adduct-induced DNA bend that allows binding of proteins which contain the high mobility group, HMG domain. Once the protein is bound to the DNA, it inserts a wedge-like phenyl group of phenylalanine 37 into the widened minor groove created by the bend. The tightly bound HMG protein causes destacking of the nucleotide bases, resulting in the DNA helix becoming kinked. In this way, Cisplatin can be thought of as a monkey wrench in the DNA repair system. With the HMG protein bound to the DNA, the modified strand is not repaired properly and so the cell dies. The success of Cisplatin depends on its ratio of efficacy between cancerous and healthy cells.
If the artery were severed, blood would flow out unimpeded, although the artery wall would contract in an effort to stop the bleeding. After losing >30% of one's blood volume blood pressure would start dropping, and with less pressure the rate of bleeding would go down. At this stage if the blood loss wasn't replaced the person could die. Losing halve to two thirds of one's blood volume is considered to be fatal even if later on blood transfusion is attempted. One's total blood volume at 70ml/kg is estimated to be between 5 to 7 liters, so that makes a blood loss of between 2,5 to 4,7 L.

Hypoparathyroidism is an uncommon condition in which your body secretes abnormally low levels of parathyroid hormone (PTH). PTH plays a key role in regulating and maintaining a balance of your body's levels of two minerals — calcium and phosphorus. The low production of PTH in hypoparathyroidism leads to abnormally low ionized calcium levels in your blood and bones and to an increase of serum phosphorus. Treatment for hypoparathyroidism consists of taking supplements to normalize your calcium and phosphorus levels. Depending on the cause of your hypoparathyroidism, you'll likely need to take supplements for life.
An abscess is a collection of pus. Pus is a thick fluid that usually contains white blood cells, dead tissue and germs (bacteria). The usual cause of an abscess is an infection with bacteria. Certain bacteria are more likely to be 'pus-forming' as they make chemicals (toxins) that can damage the body's tissues.
Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. You may have sleep apnea if you snore loudly, and you feel tired even after a full night's sleep. The main types of sleep apnea are: Obstructive sleep apnea, the more common form that occurs when throat muscles relax. Central sleep apnea, which occurs when your brain doesn't send proper signals to the muscles that control breathing. Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, occurs when someone has both obstructive sleep apnea and central sleep apnea. If you think you might have any form of sleep apnea, see your doctor. Treatment can ease your symptoms and may help prevent heart problems and other complications.

What It's Like To Get Laser Eye Surgery
What causes rheumatic fever? Rheumatic fever is not an infection itself, but rather the result of an untreated strep infection. When your body senses the strep infection, it sends antibodies to fight it. Sometimes, these antibodies attack the tissues of your joints or heart instead. If the antibodies attack your heart, they can cause your heart valves to swell, which can lead to scarring of the valve "doors" (called leaflets or cusps). Who is at risk for rheumatic fever? Fewer than 0.3% of people who have strep throat also get rheumatic fever. Rheumatic fever is most common among children aged 5 to 15, but adults may have the condition as well. Doctors think that a weakened immune system may make some people more likely to get rheumatic fever. And, although antibiotic medicines have reduced the number of cases of rheumatic fever in developed countries, there are still thousands of reported cases. What are the symptoms of rheumatic fever and how is it diagnosed? Symptoms of rheumatic fever usually begin 1 to 6 weeks after you have had a strep infection. They are Fever Joint pain or swelling in your wrists, elbows, knees, or ankles Small bumps under the skin over your elbows or knees (called nodules) A raised, red rash on your chest, back, or stomach Stomach pain or feeling less hungry Weakness, shortness of breath, or feeling very tired Your doctor will begin by doing a throat culture to find out if you have a strep infection. Then, your doctor will use a stethoscope to listen to your heart. He or she will also look for nodules on your joints. Sometimes, blood tests, chest x-rays, or an electrocardiogram (ECG or EKG) may be needed for a more definite diagnosis. How is rheumatic fever treated? Rheumatic fever must be treated right away. If you have a sore throat that lasts longer than 3 days, or if you have a fever and headache along with your sore throat, you should see your doctor for a throat culture. Even if you do not have a sore throat but have a fever and a skin rash, this could also mean a strep infection, and you should get tested. Remember rheumatic fever can result from an untreated strep infection, so it is very important to treat the infection before it leads to a worse condition.
