Paget's Disease of Bone

What is Paget's disease of bone?

Paget's disease of bone is a chronic bone disorder. Normally, there is a process in which your bones break down and then regrow. In Paget's disease, this process is abnormal. There is excessive breakdown and regrowth of bone. Because the bones regrow too quickly, they are bigger and softer than normal. They may be misshapen and easily fractured (broken). Paget's usually affects just one or a few bones.

Researchers do not know for sure what causes Paget's disease. Environmental factors may play a role. In some cases, the disease runs in families, and several genes have been linked to the disease.

The disease is more common in older people and those of northern European heritage. If you have a close relative who has Paget's, you are much more likely to have it.

Many people do not know that they have Paget's, because it often has no symptoms. When there are symptoms, they are similar to those of arthritis and other disorders. The symptoms include:

• Pain, which may be due to the disease or to arthritis, which can be a complication of Paget's
• Headaches and hearing loss, which can happen when Paget's disease affects the skull
• Pressure on the nerves, which can happen when Paget's disease affects the skull or spine
• Increased head size, bowing of a limb, or curvature of the spine. This can happen in advanced cases.
• Hip pain, if Paget's disease affects the pelvis or thighbone
• Damage to the cartilage of your joints, which may lead to arthritis

Usually, Paget's disease gets worse slowly over time. It does not spread to normal bones.

Paget's disease can lead to other complications, such as:

• Arthritis, because the misshapen bones can cause increased pressure and more wear and tear on the joints
• Heart failure. In severe Paget's disease, the heart has to work harder to pump blood to affected bones. Heart failure is more likely if you also have hardening of the arteries.
• Kidney stones, which can happen when the excessive breakdown of the bone leads to extra calcium in the body
• Nervous system problems, since the bones can cause pressure on the brain, spinal cord, or nerves. There may also be reduced blood flow to the brain and spinal cord.
• Osteosarcoma, cancer of the bone
• Loose teeth, if Paget's disease affects the facial bones
• Vision loss, if Paget's disease in the skull affects the nerves. This is rare.

Your health care provider may use many tools to make a diagnosis:

• A medical history, which includes asking about your symptoms
• A physical exam
• An x-ray of the affected bones. Paget's disease is almost always diagnosed using x-rays.
• An alkaline phosphatase blood test
• A bone scan

Sometimes the disease is found by accident when one of these tests is done for another reason.

To avoid complications, it is important to find and treat Paget's disease early. The treatments include:

• Medicines. There are several different medicines to treat Paget's disease. The most common type is bisphosphonates. They help reduce bone pain and stop or slow down the progress of the disease.
• Surgery is sometimes needed for certain complications of the disease. There are surgeries to
  • Allow fractures (broken bones) to heal in a better position
  • Replace joints such as the knee and hip when there is severe arthritis
  • Realign a deformed bone to reduce the pain in weight-bearing joints, especially the knees
  • Reduce pressure on a nerve, if enlargement of the skull or spine injuries effects the nervous system

Diet and exercise do not treat Paget's, but they can help to keep your skeleton healthy. If you do not have kidney stones, you should make sure to get enough calcium and vitamin D through your diet and supplements. Besides keeping your skeleton healthy, exercise can prevent weight gain and maintain the mobility of your joints. Talk with your health care provider before you start a new exercise program. You need to make sure that the exercise does not put too much stress on the affected bones.

Pain

What is pain?

Pain is a signal in your nervous system that something may be wrong. It is an unpleasant feeling, such as a prick, tingle, sting, burn, or ache. Each person feels pain differently, even if the reason for the pain is the same. Pain may be sharp or dull. It may be mild or severe. Pain may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen, chest, or pelvis, or you may feel it all over.

Pain can help alert you that there is a problem. If you never felt pain, you might seriously hurt yourself without knowing it, or you might not realize you have a medical problem that needs treatment. Finding out what's causing your pain will help your health care provider determine the best way to manage or treat it.

Patterns and types of pain are named based on how long and how often you have pain. These include:

• Acute pain usually happens suddenly because of a disease, injury, or inflammation (irritation, redness, and/or swelling). This type of pain is often sharp and acts as a warning that something is wrong. It usually goes away when the cause is treated or healed, though sometimes it can turn into chronic pain. Some examples of causes of acute pain include broken bones or dental issues.
• Chronic pain lasts for longer than three months or the time in which you should have healed. It can affect all aspects of daily life, including your mood and relationships. Some conditions that might cause chronic pain include arthritis or back problems.
• Episodic pain can happen from time to time and may occur with long-term medical conditions. Some conditions that might cause episodic pain include sickle cell disease or chronic migraines.

Pain may also be categorized by what is likely to be the cause of the pain. Pain may be described as nociceptive (caused by tissue damage or inflammation), neuropathic (caused by nerve damage), or nociplastic (caused by changes in how your nervous system processes pain).

Understanding what causes pain and why people feel it differently may be difficult. Often, it's easier to find the cause of acute pain due to an injury than the cause of chronic pain, or you may have an ongoing cause of pain, such as cancer.

In some cases, there is no clear cause. Environmental factors and psychological factors such as stress and beliefs about pain may affect the way you feel pain and respond to treatment.

You are the only one who knows how your pain feels. Your provider can best measure your pain by how you report it. They may ask you:

• Where is the pain in your body?
• How long have you had the pain?
• How does the pain feel, such as stinging, burning, or sharp?
• How often do you have pain?
• When do you feel pain, such as in the morning, evening, or all the time?
• What relieves the pain?
• How does pain affect your daily life?
• Is the pain mild, moderate, or severe?
• To rate the pain on a scale.

If the cause of your pain is unknown, your provider may also do a physical exam and order blood tests or other medical tests to help find the cause.

Pain is not always curable, but there are many ways to manage and treat it. Treatment depends on the cause and type of pain. Treatments may include medicines, such as pain relievers. There are also non-drug treatments, such as acupuncture, physical therapy, and sometimes surgery.

Depending on the cause of your pain and your symptoms, your provider may recommend lifestyle changes. These may include suggestions for:

• Eating a healthy diet
• Adding exercise
• Losing weight
• Managing stress
• Improving mental health

Palliative Care

Palliative care is treatment of the discomfort, symptoms, and stress of serious illness. It provides relief from distressing symptoms including:

• Pain
• Shortness of breath
• Fatigue
• Constipation
• Nausea
• Loss of appetite
• Problems with sleep

It can also help you deal with the side effects of the medical treatments you're receiving.

Hospice care, care at the end of life, always includes palliative care. But you may receive palliative care at any stage of an illness. The goal is to make you comfortable and improve your quality of life.

Pancreatic Diseases

The pancreas is a gland behind your stomach and in front of your spine. It produces juices that help break down food and hormones that help control blood sugar levels. Problems with the pancreas can lead to many health problems. These include:

• Pancreatitis, or inflammation of the pancreas: This happens when digestive enzymes start digesting the pancreas itself
• Pancreatic cancer
• Cystic fibrosis, a genetic disorder in which thick, sticky mucus can also block tubes in your pancreas

The pancreas also plays a role in diabetes. In type 1 diabetes, the beta cells of the pancreas no longer make insulin because the body's immune system has attacked them. In type 2 diabetes, the pancreas loses the ability to secrete enough insulin in response to meals.

Peptic Ulcer

A peptic ulcer is a sore in the lining of your stomach or your duodenum, the first part of your small intestine. A burning stomach pain is the most common symptom. The pain:

• Starts between meals or during the night
• Briefly stops if you eat or take antacids
• Lasts for minutes to hours
• Comes and goes for several days or weeks

Peptic ulcers happen when the acids that help you digest food damage the walls of the stomach or duodenum. The most common cause is infection with a bacterium called Helicobacter pylori. Another cause is the long-term use of nonsteroidal anti-inflammatory medicines (NSAIDs) such as aspirin and ibuprofen. Stress and spicy foods do not cause ulcers, but can make them worse.

To see if you have an H. pylori infection, your doctor will test your blood, breath, or stool. Your doctor also may look inside your stomach and duodenum by doing an endoscopy or x-ray.

Peptic ulcers will get worse if not treated. Treatment may include medicines to reduce stomach acids or antibiotics to kill H. pylori. Antacids and milk can't heal peptic ulcers. Not smoking and avoiding alcohol can help. You may need surgery if your ulcers don't heal.
