Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance. Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you're otherwise in good health, you may recover normal or nearly normal kidney function.
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.
To use the diaphragm, first cover the inside of it with spermicide. Then insert it into your vagina so that it covers your cervix. You can insert the diaphragm up to 6 hours before sex. You should leave it in for at least 6 hours after the last time you have sex.
Fillings are a way for dentists to restore a partially decayed tooth. While many people fear the dentist, this procedure is typically quick, effective, and inexpensive. Without fillings, cavities can rapidly worsen. Seeing a dentist regularly can help you to monitor the condition of your teeth and plan for corrective procedures. According to the National Institute of Dental and Craniofacial Research, nearly 93 percent of adults between the ages of 20 and 64 have cavities, and at least 29 percent have decay that is untreated. Dentists can quickly identify tooth decay and then come up with a plan of action that involves filling teeth and restoring adverse conditions. You can do your part by sticking to a solid at-home oral hygiene routine. By simply brushing twice a day with a fluoride-treated toothpaste and flossing regularly, you can prevent the build up of bacteria-rich plaque and eliminate cavity-causing conditions.
Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. You're most likely to contract hepatitis A from contaminated food or water or from close contact with someone who's infected. Mild cases of hepatitis A don't require treatment, and most people who are infected recover completely with no permanent liver damage. Practicing good hygiene, including washing hands frequently, is one of the best ways to protect against hepatitis A. Vaccines are available for people most at risk.
Retinitis pigmentosa is a rare, inherited degenerative eye disease that causes severe vision impairment. Symptoms often begin in childhood. They include decreased vision at night or in low light and loss of side vision (tunnel vision).
Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The function of pulmonary circulation is to exchange carbon dioxide for oxygen in the blood. It is the passage of blood from the heart to the capillaries of the lungs, where the gases are exchanged, and back to the heart to be pumped around the body.
