Von Hippel-Lindau Disease

What is Von Hippel-Lindau disease (VHL)?

Von Hippel-Lindau disease (VHL) is a rare disease that causes tumors and cysts to grow in your body. They can grow in your brain and spinal cord, kidneys, pancreas, adrenal glands, and reproductive tract. The tumors are usually benign (non-cancerous). But some tumors, such as those in the kidney and pancreas, can become cancerous.

VHL is a genetic disease. It is inherited, which means that it is passed down from parent to child.

Symptoms of VHL depend on the size and location of the tumors. They may include:

• Headaches
• Problems with balance and walking
• Dizziness
• Weakness of the limbs
• Vision problems
• High blood pressure

Detecting and treating VHL early is important. Your health care provider may suspect that you have VHL if you have certain patterns of cysts and tumors. There is a genetic test for VHL. If you have it, you will need other tests, including imaging tests, to look for tumors and cysts.

Treatment can vary, depending on the location and size of the tumors and cysts. It usually involves surgery. Certain tumors may be treated with radiation therapy. The goal is to treat growths while they are small and before they do permanent damage. You will need to have careful monitoring by a doctor and/or medical team familiar with the disorder.

Wilson Disease

Wilson disease is a rare inherited disorder that prevents your body from getting rid of extra copper. You need a small amount of copper from food to stay healthy. Too much copper is poisonous.

Normally, your liver releases extra copper into bile, a digestive fluid. With Wilson disease, the copper builds up in your liver, and it releases the copper directly into your bloodstream. This can cause damage to your brain, kidneys, and eyes.

Wilson disease is present at birth, but symptoms usually start between ages 5 and 35. It first attacks the liver, the central nervous system or both. The most characteristic sign is a rusty brown ring around the cornea of the eye. A physical exam and laboratory tests can diagnose it.

Treatment is with drugs to remove the extra copper from your body. You need to take medicine and follow a low-copper diet for the rest of your life. Don't eat shellfish or liver, as these foods may contain high levels of copper. At the beginning of treatment, you'll also need to avoid chocolate, mushrooms, and nuts. Have your drinking water checked for copper content and don't take multivitamins that contain copper.

With early detection and proper treatment, you can enjoy good health.

Women's Health

Women have unique health issues. And some of the health issues that affect both men and women can affect women differently.

Unique issues include pregnancy, menopause, and conditions of the female organs. Women can have a healthy pregnancy by getting early and regular prenatal care. They should also get recommended breast cancer, cervical cancer, and bone density screenings.

Women and men also have many of the same health problems. But these problems can affect women differently. For example:

• Women are more likely to die following a heart attack than men
• Women are more likely to show signs of depression and anxiety than men
• The effects of sexually transmitted infections (STIs) can be more serious in women
• Osteoarthritis affects more women than men
• Women are more likely to have urinary tract problems

Acute Flaccid Myelitis

What is acute flaccid myelitis (AFM)?

Acute flaccid myelitis (AFM) is a neurologic disease. It is rare, but serious. It affects an area of the spinal cord called gray matter. This can cause the muscles and reflexes in the body to become weak.

Because of these symptoms, some people call AFM a "polio-like" illness. But it is different from polio. AFM is not caused by polioviruses.

AFM can be caused by several different viruses. Researchers think that enteroviruses have been causing the recent increases in the number of children with AFM. AFM can also be caused by other viruses, including flaviviruses, herpesviruses, and adenoviruses.

Most people with AFM had a mild respiratory illness or fever (like you would get from a viral infection) before they got AFM.

Anyone can get AFM, but most cases (more than 90%) have been in young children.

Most people with AFM will suddenly have:

• Arm or leg weakness
• A loss of muscle tone and reflexes

Some people also have other symptoms, including:

• Facial drooping/weakness
• Trouble moving the eyes
• Drooping eyelids
• Trouble swallowing
• Slurred speech
• Pain in the arms, legs, back, or neck

Sometimes AFM can weaken the muscles that you need for breathing. This can lead to respiratory failure, which is very serious. If you get respiratory failure, you may need to use a ventilator (breathing machine) to help you breathe.

If you or your child develops any of these symptoms, get medical care right away.

AFM causes many of the same symptoms as other neurologic diseases, such as transverse myelitis and Guillain-Barre syndrome. This can make it difficult to diagnose. To find out if you have AFM, your doctor may use:

• A neurologic exam, including looking at where there is weakness, poor muscle tone, and decreased reflexes
• An MRI to look at the spinal cord and brain
• Lab tests on the cerebrospinal fluid (the fluid around the brain and spinal cord)
• Nerve conduction and electromyography (EMG) studies. These tests check nerve speed and the response of muscles to the messages from the nerves.

It is important that the tests are done as soon as possible after the symptoms start.

There is no specific treatment for AFM. A doctor who specializes in treating brain and spinal cord illnesses (neurologist) may recommend treatments for specific symptoms. For example, physical and/or occupational therapy may help with arm or leg weakness. Researchers do not know the long-term outcomes of people who get AFM.

There is no specific way to prevent AFM. But you can take steps to prevent getting sick from a virus by:

• Washing your hands often with soap and water
• Avoiding touching your face with unwashed hands
• Avoiding close contact with people who are sick
• Cleaning and disinfecting surfaces that you frequently touch, including toys
• Covering coughs and sneezes with a tissue or upper shirt sleeve, not hands
• Staying home when sick
