A molar pregnancy — also known as hydatidiform mole — is a noncancerous (benign) tumor that develops in the uterus. A molar pregnancy starts when an egg is fertilized, but instead of a normal, viable pregnancy resulting, the placenta develops into an abnormal mass of cysts. In a complete molar pregnancy, there's no embryo or normal placental tissue. In a partial molar pregnancy, there's an abnormal embryo and possibly some normal placental tissue. The embryo begins to develop but is malformed and can't survive. A molar pregnancy can have serious complications — including a rare form of cancer — and requires early treatment.

Subarachnoid hemorrhage is bleeding in the space between your brain and the surrounding membrane (subarachnoid space). Bleeding usually results from the rupture of an abnormal bulge in a blood vessel in your brain (brain aneurysm). Sometimes an abnormal tangle of blood vessels in your brain (arteriovenous malformation), trauma or other events cause bleeding. A subarachnoid hemorrhage may lead to permanent brain damage or death if not treated.

An intra-aortic balloon pump (IABP) is a mechanical device that helps the heart pump blood. This device is inserted into the aorta, the body's largest artery. It is a long, thin tube called a catheter with a balloon on the end of it. If you are hospitalized, your doctor may insert an IABP. Your doctor will numb an area of your leg and thread the IABP through the femoral artery in your leg into your aorta. He or she then positions the IABP at the center of your aorta, below your heart. The doctor will use an X-ray machine during this procedure to help accurately position the IABP. Why is it used? An IABP might be used to stabilize a person who is in the hospital for acute mitral valve regurgitation or severe heart failure. An IABP is only used for a short period of time (hours to days). A long-term treatment will likely be needed, such as valve surgery or the insertion of a left ventricular assist device (LVAD).

OverviewSymptomsTestingComplicationsTreatmentPreventionTakeawayRead This Next What is gonorrhea? Highlights Some people may never develop noticeable symptoms. Gonorrhea is usually treated with an antibiotic injection or oral antibiotics. You’re at a higher risk of contracting gonorrhea if you’ve had any other STDs. Gonorrhea is a sexually transmitted disease (STD). It’s caused by infection with the bacterium Neisseria gonorrhoeae. It tends to infect warm, moist areas of the body, including the: urethra (the tube that drains urine from the urinary bladder) eyes throat vagina anus female reproductive tract (the fallopian tubes, cervix, and uterus) Gonorrhea passes from person to person through unprotected oral, anal, or vaginal sex. People with numerous sexual partners or those who don’t use a condom are at greatest risk of infection. The best protections against infection are abstinence, monogamy (sex with only one partner), and proper condom usage. Behaviors that make a person more likely to engage in unprotected sex also increase the likelihood of infection. These behaviors include alcohol abuse and illegal drug abuse, particularly intravenous drug use. Advertisement Symptoms of gonorrhea Symptoms

Most women have between 11 and 13 menstrual periods each year. You may be different: You may have more or fewer. Missed or irregular periods must be looked at in terms of what is normal for you. Menstrual periods are often irregular during the first few years after menstruation starts. It may take several years for the hormones that control menstruation to reach a balance. Menstrual periods also may be very irregular at the other end of the menstrual years. Many women realize that they are approaching perimenopause and menopause when their otherwise regular periods become irregular. Menopause occurs when it has been 12 months since you had a menstrual period. Pregnancy is the most common cause of a missed period. If you might be pregnant, treat yourself as if you are pregnant until you know for sure. Use a home pregnancy test as the first step to finding out whether you are pregnant.

Takayasu's arteritis (tah-kah-YAH-sooz ahr-tuh-RIE-tis) is a rare type of vasculitis, a group of disorders that cause blood vessel inflammation. In Takayasu's arteritis, the inflammation damages the aorta — the large artery that carries blood from your heart to the rest of your body — and its main branches. The disease can lead to blockages or narrowed arteries (stenosis) or abnormally dilated arteries (aneurysms). Takayasu's arteritis can also lead to arm or chest pain and high blood pressure and eventually to heart failure or stroke. If you don't have symptoms, you may not need treatment. Or you may need medications to control the inflammation in the arteries and prevent complications. But even with treatment, relapses are common.

Can the flu be treated? Yes. There are prescription medications called “antiviral drugs” that can be used to treat flu illness. What are antiviral drugs? Antiviral drugs are prescription medicines (pills, liquid, an inhaled powder, or an intravenous solution) that fight against the flu in your body. Antiviral drugs are not sold over-the-counter. You can only get them if you have a prescription from your doctor or health care provider. Antiviral drugs are different from antibiotics, which fight against bacterial infections. What should I do if I think I have the flu? If you get the flu, antiviral drugs are a treatment option. Check with your doctor promptly if you are at high risk of serious flu complications (see box below for the full list of high risk factors). Flu symptoms can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Your doctor may prescribe antiviral drugs to treat your flu illness. Should I still get a flu vaccine? Yes. Antiviral drugs are not a substitute for getting a flu vaccine. While flu vaccine can vary in how well it works, a flu vaccine is the first and best way to prevent seasonal influenza. Antiviral drugs are a second line of defense to treat the flu (including seasonal flu and variant flu viruses) if you get sick.

This video: Multiple myeloma is a cancer that forms in a type of white blood cell called a plasma cell. Plasma cells help you fight infections by making antibodies that recognize and attack germs. Multiple myeloma causes cancer cells to accumulate in the bone marrow, where they crowd out healthy blood cells. Rather than produce helpful antibodies, the cancer cells produce abnormal proteins that can cause kidney problems. Treatment for multiple myeloma isn't always necessary. If you're not experiencing signs and symptoms, you may not require treatment. If signs and symptoms develop, a number of treatments can help control your multiple myeloma.

The preferred route of access for temporary transvenous pacing is the internal jugular vein followed by subclavian and femoral veins. However, all the major venous access sites (internal and external jugular, subclavian, brachial, femoral) have been used and each is associated with particular problems.

Conversion disorder, also called functional neurological symptom disorder, is a condition in which you show psychological stress in physical ways. The condition was so named to describe a health problem that starts as a mental or emotional crisis — a scary or stressful incident of some kind — and converts to a physical problem.

Bleeding usually occurs from only one nostril. If the bleeding is heavy enough, the blood can fill up the nostril on the affected side and overflow within the nasopharynx (the area inside the nose where the two nostrils merge), spilling into the other nostril to cause bleeding from both sides. Blood can also drip back into the throat or down into the stomach, causing a person to spit or even vomit blood. Signs of excessive blood loss include dizziness, light-headedness, confusion, and fainting. Excessive blood loss from nosebleeds is rare. Additional bleeding from other parts of the body, such as bleeding gums when brushing teeth, blood in urine or bowel movements, or easy bruising may indicate an inability of the blood to clot. Additional bleeding or easy bruising can be a sign of a more significant medical problem.

Face transplant candidates go through an extensive screening process that is likely to last several months. This screening includes a psychiatric and social support evaluation and a series of imaging tests to help determine a patient’s physical and mental readiness for the procedure. If, upon completion of the screening process, it is determined that a patient is a suitable candidate, we will place the patient on a transplant waiting list. We will then begin working with the New England Organ Bank (NEOB) team to find a donor who matches the recipient’s tissue requirements – e.g., similar age, right blood type. This search could take many months, and, if a suitable donor is not found within one year, we will speak with the patient to determine whether they’re willing to continue waiting. When a donor is found, we will immediately inform the patient about when to arrive at the hospital for the operation. As the timing for this type of procedure is extremely important, patients are expected to be readily available, i.e., reside within a 12-hour travel radius of BWH.

Though most snakes aren't venomous, the ones with a deadly bite are so scary that many researchers think humans evolved to naturally fear the sinuous creatures. With good reason. In the video, two men milk the venom of a Russell's viper and then show what happens when one drop of that venom mixes with a glassful of human blood. It's terrifying.

This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve’s place. The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI).

If levels of both vitamins are extremely high, there is more than a 17-fold greater risk that a child will develop autism, the researchers said. Most of the women in the study said they took multivitamins — which would include folic acid and vitamin B12 — throughout their pregnancy.

Dizziness is a word that is often used to describe two different feelings. It is important to know exactly what you mean when you say "I feel dizzy," because it can help you and your doctor narrow down the list of possible problems. Lightheadedness is a feeling that you are about to faint or "pass out." Although you may feel dizzy, you do not feel as though you or your surroundings are moving. Lightheadedness often goes away or improves when you lie down. If lightheadedness gets worse, it can lead to a feeling of almost fainting or a fainting spell (syncope). You may sometimes feel nauseated or vomit when you are lightheaded. Vertigo is a feeling that you or your surroundings are moving when there is no actual movement. You may feel as though you are off balance, spinning, whirling, falling, or tilting. When you have severe vertigo, you may feel very nauseated or vomit. You may have trouble walking or standing, and you may lose your balance and fall.

Paget's disease of the breast or Paget disease of the breast (/ˈpædʒᵻt/, rhymes with "gadget") (also known as Paget's disease of the nipple) is a malignant condition that outwardly may have the appearance of eczema, with skin changes involving the nipple of the breast.
