<s>[INST] Human: What is (are) Tourette syndrome ? [/INST] Assistant: Tourette syndrome is a complex disorder characterized by repetitive, sudden, and involuntary movements or noises called tics. Tics usually appear in childhood, and their severity varies over time. In most cases, tics become milder and less frequent in late adolescence and adulthood. Tourette syndrome involves both motor tics, which are uncontrolled body movements, and vocal or phonic tics, which are outbursts of sound. Some motor tics are simple and involve only one muscle group. Simple motor tics, such as rapid eye blinking, shoulder shrugging, or nose twitching, are usually the first signs of Tourette syndrome. Motor tics also can be complex (involving multiple muscle groups), such as jumping, kicking, hopping, or spinning. Vocal tics, which generally appear later than motor tics, also can be simple or complex. Simple vocal tics include grunting, sniffing, and throat-clearing. More complex vocalizations include repeating the words of others (echolalia) or repeating one's own words (palilalia). The involuntary use of inappropriate or obscene language (coprolalia) is possible, but uncommon, among people with Tourette syndrome. In addition to frequent tics, people with Tourette syndrome are at risk for associated problems including attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, depression, and problems with sleep. </s> |

<s>[INST] Human: What is (are) Adrenal Gland Disorders ? [/INST] Assistant: The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including sex hormones and cortisol. Cortisol helps you respond to stress and has many other important functions. With adrenal gland disorders, your glands make too much or not enough hormones. In Cushing's syndrome, there's too much cortisol, while with Addison's disease, there is too little. Some people are born unable to make enough cortisol. Causes of adrenal gland disorders include - Genetic mutations - Tumors including pheochromocytomas - Infections - A problem in another gland, such as the pituitary, which helps to regulate the adrenal gland - Certain medicines Treatment depends on which problem you have. Surgery or medicines can treat many adrenal gland disorders. NIH: National Institute of Child Health and Human Development </s> |

<s>[INST] Human: What to do for Causes of Diabetes ? [/INST] Assistant: - Diabetes is a complex group of diseases with a variety of causes. Scientists believe genes and environmental factors interact to cause diabetes in most cases. - People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both. - Insulin is a hormone made by beta cells in the pancreas. Insulin helps cells throughout the body absorb and use glucose for energy. If the body does not produce enough insulin or cannot use insulin effectively, glucose builds up in the blood instead of being absorbed by cells in the body, and the body is starved of energy. - Prediabetes is a condition in which blood glucose levels or A1C levels are higher than normal but not high enough to be diagnosed as diabetes. People with prediabetes can substantially reduce their risk of developing diabetes by losing weight and increasing physical activity. - The two main types of diabetes are type 1 diabetes and type 2 diabetes. Gestational diabetes is a third form of diabetes that develops only during pregnancy. - Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. - Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. - Scientists believe gestational diabetes is caused by the hormonal changes and metabolic demands of pregnancy together with genetic and environmental factors. Risk factors for gestational diabetes include being overweight and having a family history of diabetes. - Monogenic forms of diabetes are relatively uncommon and are caused by mutations in single genes that limit insulin production, quality, or action in the body. - Other types of diabetes are caused by diseases and injuries that damage the pancreas; certain chemical toxins and medications; infections; and other conditions. </s> |
<s>[INST] Human: What is (are) Prostate Cancer ? [/INST] Assistant: How Tumors Form The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong -- cells become abnormal and form more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, which means not cancerous, or malignant, which means cancerous. How Prostate Cancer Occurs Prostate cancer occurs when a tumor forms in the tissue of the prostate, a gland in the male reproductive system. In its early stage, prostate cancer needs the male hormone testosterone to grow and survive. The prostate is about the size of a large walnut. It is located below the bladder and in front of the rectum. The prostate's main function is to make fluid for semen, a white substance that carries sperm. Prostate cancer is one of the most common types of cancer among American men. It is a slow-growing disease that mostly affects older men. In fact, more than 60 percent of all prostate cancers are found in men over the age of 65. The disease rarely occurs in men younger than 40 years of age. Prostate Cancer Can Spread Sometimes, cancer cells break away from a malignant tumor in the prostate and enter the bloodstream or the lymphatic system and travel to other organs in the body. When cancer spreads from its original location in the prostate to another part of the body such as the bone, it is called metastatic prostate cancer -- not bone cancer. Doctors sometimes call this distant disease. Surviving Prostate Cancer Today, more men are surviving prostate cancer than ever before. Treatment can be effective, especially when the cancer has not spread beyond the region of the prostate. </s> |
<s>[INST] Human: How many people are affected by STING-associated vasculopathy with onset in infancy ? [/INST] Assistant: The prevalence of this condition is unknown. Only a few affected individuals have been described in the medical literature. </s> |
<s>[INST] Human: What are the genetic changes related to myoclonus-dystonia ? [/INST] Assistant: Mutations in the SGCE gene cause myoclonus-dystonia. The SGCE gene provides instructions for making a protein called epsilon ()-sarcoglycan, whose function is unknown. The -sarcoglycan protein is located within the cell membranes of many tissues, but it is most abundant in nerve cells (neurons) in the brain and in muscle cells. SGCE gene mutations that cause myoclonus-dystonia result in a shortage of -sarcoglycan protein. The protein shortage seems to affect the regions of the brain involved in coordinating movements (the cerebellum) and controlling movements (the basal ganglia). Thus, the movement problems experienced by people with myoclonus-dystonia are caused by dysfunction in the brain, not the muscles. People with this condition show no signs of muscle disease. It is unknown why SGCE gene mutations seem only to affect the brain. </s> |
<s>[INST] Human: What is the outlook for Fibromuscular Dysplasia ? [/INST] Assistant: Currently there is no cure for FMD. Medicines and angioplasty can reduce the risk of initial or recurrent stroke. In rare cases, FMD-related aneurysms can burst and bleed into the brain, causing stroke, permanent nerve damage, or death. </s> |

<s>[INST] Human: How to diagnose Mitral Valve Prolapse ? [/INST] Assistant: Mitral valve prolapse (MVP) most often is detected during a routine physical exam. During the exam, your doctor will listen to your heart with a stethoscope.
Stretched valve flaps can make a clicking sound as they shut. If the mitral valve is leaking blood back into the left atrium, your doctor may heart a heart murmur or whooshing sound.
However, these abnormal heart sounds may come and go. Your doctor may not hear them at the time of an exam, even if you have MVP. Thus, you also may have tests and procedures to diagnose MVP.
Diagnostic Tests and Procedures
Echocardiography
Echocardiography (echo) is the most useful test for diagnosing MVP. This painless test uses sound waves to create a moving picture of your heart.
Echo shows the size and shape of your heart and how well your heart chambers and valves are working. The test also can show areas of heart muscle that aren't contracting normally because of poor blood flow or injury to the heart muscle.
Echo can show prolapse of the mitral valve flaps and backflow of blood through the leaky valve.
There are several types of echo, including stress echo. Stress echo is done before and after a stress test. During a stress test, you exercise or take medicine (given by your doctor) to make your heart work hard and beat fast.
You may have stress echo to find out whether you have decreased blood flow to your heart (a sign of coronary heart disease).
Echo also can be done by placing a tiny probe in your esophagus to get a closer look at the mitral valve. The esophagus is the passage leading from your mouth to your stomach.
The probe uses sound waves to create pictures of your heart. This form of echo is called transesophageal (tranz-ih-sof-uh-JEE-ul) echocardiography, or TEE.
Doppler Ultrasound
A Doppler ultrasound is part of an echo test. A Doppler ultrasound shows the speed and direction of blood flow through the mitral valve.
Other Tests
Other tests that can help diagnose MVP include:
A chest x ray. This test is used to look for fluid in your lungs or to show whether your heart is enlarged.
An EKG (electrocardiogram). An EKG is a simple test that records your heart's electrical activity. An EKG can show how fast your heart is beating and whether its rhythm is steady or irregular. This test also records the strength and timing of electrical signals as they pass through your heart. </s> |
<s>[INST] Human: What is (are) Throat Cancer ? [/INST] Assistant: Throat cancer is a type of head and neck cancer. Throat cancer has different names, depending on what part of the throat is affected. The different parts of the throat are called the oropharynx, the hypopharynx, and the nasopharynx. Sometimes the larynx, or voice box, is also included. The main risk factors for throat cancer are smoking or using smokeless tobacco and use of alcohol. Symptoms of throat cancer may include - Trouble breathing or speaking - Frequent headaches - Pain or ringing in the ears - Trouble swallowing - Ear pain Treatments include surgery, radiation therapy, and chemotherapy. NIH: National Cancer Institute </s> |
<s>[INST] Human: How to diagnose Heart Palpitations ? [/INST] Assistant: First, your doctor will want to find out whether your palpitations are harmless or related to a heart problem. He or she will ask about your symptoms and medical history, do a physical exam, and recommend several basic tests.
This information may point to a heart problem as the cause of your palpitations. If so, your doctor may recommend more tests. These tests will help show what the problem is, so your doctor can decide how to treat it.
The cause of palpitations may be hard to diagnose, especially if symptoms don't occur regularly.
Specialists Involved
Several types of doctors may work with you to diagnose and treat your palpitations. These include a:
Primary care doctor
Cardiologist (a doctor who specializes in diagnosing and treating heart diseases and conditions)
Electrophysiologist (a cardiologist who specializes in the heart's electrical system)
Medical History
Your doctor will ask questions about your palpitations, such as:
When did they begin?
How long do they last?
How often do they occur?
Do they start and stop suddenly?
Does your heartbeat feel steady or irregular during the palpitations?
Do other symptoms occur with the palpitations?
Do your palpitations have a pattern? For example, do they occur when you exercise or drink coffee? Do they happen at a certain time of day?
Your doctor also may ask about your use of caffeine, alcohol, supplements, and illegal drugs.
Physical Exam
Your doctor will take your pulse to find out how fast your heart is beating and whether its rhythm is normal. He or she also will use a stethoscope to listen to your heartbeat.
Your doctor may look for signs of conditions that can cause palpitations, such as an overactive thyroid.
Diagnostic Tests
Often, the first test that's done is an EKG (electrocardiogram). This simple test records your heart's electrical activity.
An EKG shows how fast your heart is beating and its rhythm (steady or irregular). It also records the strength and timing of electrical signals as they pass through your heart.
Even if your EKG results are normal, you may still have a medical condition that's causing palpitations. If your doctor suspects this is the case, you may have blood tests to gather more information about your heart's structure, function, and electrical system.
Holter or Event Monitor
A standard EKG only records the heartbeat for a few seconds. It won't detect heart rhythm problems that don't happen during the test. To diagnose problems that come and go, your doctor may have you wear a Holter or event monitor.
A Holter monitor records the hearts electrical activity for a full 24- or 48-hour period. You wear patches called electrodes on your chest. Wires connect the patches to a small, portable recorder. The recorder can be clipped to a belt, kept in a pocket, or hung around your neck.
During the 24- or 48-hour period, you do your usual daily activities. You use a notebook to record any symptoms you have and the time they occur. You then return both the recorder and the notebook to your doctor to read the results. Your doctor can see how your heart was beating at the time you had symptoms.
An event monitor is similar to a Holter monitor. You wear an event monitor while doing your normal activities. However, an event monitor only records your heart's electrical activity at certain times while you're wearing it.
For many event monitors, you push a button to start the monitor when you feel symptoms. Other event monitors start automatically when they sense abnormal heart rhythms.
You can wear an event monitor for weeks or until symptoms occur.
Holter or Event Monitor
Echocardiography
Echocardiography uses sound waves to create a moving picture of your heart. The picture shows the size and shape of your heart and how well your heart chambers and valves are working.
The test also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow.
Stress Test
Some heart problems are easier to diagnose when your heart is working hard and beating fast. During stress testing, you exercise to make your heart work hard and beat fast while heart tests are done. If you cant exercise, you may be given medicine to make your heart work hard and beat fast. </s> |
<s>[INST] Human: What is (are) Whipple Disease ? [/INST] Assistant: Whipple disease is a rare bacterial infection that primarily affects the small intestine. The infection may spread to any organ in the body; however, it more commonly affects the
- joints - central nervous system, which includes the brain, the spinal cord, and nerves located throughout the body - heart - eyes - lungs
Left untreated, Whipple disease gets worse and is usually life threatening. </s> |
<s>[INST] Human: What are the genetic changes related to congenital stromal corneal dystrophy ? [/INST] Assistant: Congenital stromal corneal dystrophy is caused by mutations in the DCN gene. This gene provides instructions for making a protein called decorin, which is involved in the organization of collagens. Collagens are proteins that strengthen and support connective tissues such as skin, bone, tendons, and ligaments. In the cornea, well-organized bundles of collagen make the cornea transparent. Decorin ensures that collagen fibrils in the cornea are uniformly sized and regularly spaced. Mutations in the DCN gene lead to the production of a defective version of decorin. This abnormal protein interferes with the organization of collagen fibrils in the cornea. As poorly arranged collagen fibrils accumulate, the cornea becomes cloudy. These corneal changes lead to reduced visual acuity and related eye abnormalities. </s> |
<s>[INST] Human: What are the genetic changes related to familial isolated pituitary adenoma ? [/INST] Assistant: FIPA can be caused by mutations in the AIP gene. The function of the protein produced from this gene is not well understood, but it is thought to act as a tumor suppressor, which means it helps prevent cells from growing and dividing in an uncontrolled way. Mutations in the AIP gene alter the protein or reduce the production of functional protein. These changes likely impair the ability of the AIP protein to control the growth and division of cells, allowing pituitary cells to grow and divide unchecked and form a tumor. It is not known why the pituitary gland is specifically affected or why certain types of pituitary adenomas develop. AIP gene mutations account for approximately 15 to 25 percent of cases of FIPA. Somatotropinomas are the most common type of tumor in these individuals. The tumors usually occur at a younger age, often in childhood, and are larger than FIPA tumors not caused by AIP gene mutations. The other genetic causes of FIPA are unknown. </s> |
<s>[INST] Human: Is pulmonary veno-occlusive disease inherited ? [/INST] Assistant: When caused by mutations in the EIF2AK4 gene, PVOD is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. In contrast, when caused by mutations in another gene, the condition can have an autosomal dominant pattern of inheritance, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In these cases, one parent of an affected individual typically has increased blood pressure in the vessels of the lungs. </s> |

<s>[INST] Human: What causes Alport syndrome ? [/INST] Assistant: What causes Alport syndrome? Alport syndrome may be caused by mutations in either the COL4A3, COL4A4, or COL4A5 genes. These genes each provide instructions for making one component of a protein called type IV collagen, which plays an important role in the glomeruli of the kidneys. Glomeruli are clusters of specialized blood vessels that remove water and waste products from the blood and create urine. Mutations in the genes mentioned above result in abnormalities of the type IV collagen in glomeruli, which prevents the kidneys from properly filtering the blood. As a result, blood and protein pass into the urine. Over time, the kidneys become scarred and many people with Alport syndrome develop kidney failure. Type IV collagen is also an important component of the organ of Corti, an inner ear structure that transforms sound waves into nerve impulses for the brain. Alterations in type IV collagen may result in abnormal inner ear function, which can lead to hearing loss. In addition, type IV collagen plays a role in the eye, where it helps maintain the shape of the lens and the normal color of the retina. Mutations found in Alport syndrome may affect the shape of the lenses and the color of the retina. </s> |

MGUS typically does not cause any problems, although some affected people may experience numbness, tingling or weakness. In some cases, MGUS may progress over time to certain forms of blood cancer (such as multiple myeloma, macroglobulinemia, or B-cell lymphoma). MGUS is thought to be a multifactorial condition that is likely associated with the effects of multiple genes in combination with lifestyle and environmental factors. People with MGUS are usually monitored closely to ensure that the levels of monoclonal protein do not rise and other problems do not develop. Those with stable levels of monoclonal protein typically do not require treatment. </s> |
<s>[INST] Human: How to prevent High Blood Pressure and Kidney Disease ? [/INST] Assistant: The best way to slow or prevent kidney disease from high blood pressure is to take steps to lower blood pressure. These steps include a combination of medication and lifestyle changes, such as
- healthy eating - physical activity - maintaining a healthy weight - quitting smoking - managing stress
No matter what the cause of the kidney disease, high blood pressure can increase damage to the kidneys. People with kidney disease should keep their blood pressure below 140/90.4
Medication
Medications that lower blood pressure can also significantly slow the progression of kidney disease. Two types of blood pressure-lowering medications, angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), have been shown effective in slowing the progression of kidney disease. Many people require two or more medications to control their blood pressure. In addition to an ACE inhibitor or an ARB, a health care provider may prescribe a diuretica medication that helps the kidneys remove fluid from the blood. A person may also need beta blockers, calcium channel blockers, and other blood pressure medications. </s> |
<s>[INST] Human: How to prevent Pneumonia ? [/INST] Assistant: Pneumonia can be very serious and even life threatening. When possible, take steps to prevent the infection, especially if you're in a high-risk group.
Vaccines
Vaccines are available to prevent pneumococcal pneumonia and the flu. Vaccines can't prevent all cases of infection. However, compared to people who don't get vaccinated, those who do and still get pneumonia tend to have:
Milder cases of the infection
Pneumonia that doesn't last as long
Fewer serious complications
Pneumococcal Pneumonia Vaccine
A vaccine is available to prevent pneumococcal pneumonia. In most adults, one shot is good for at least 5 years of protection. This vaccine often is recommended for:
People who are 65 years old or older.
People who have chronic (ongoing) diseases, serious long-term health problems, or weak immune systems. For example, this may include people who have cancer, HIV/AIDS, asthma, or damaged or removed spleens.
People who smoke.
Children who are younger than 5 years old.
Children who are 518 years of age with certain medical conditions, such as heart or lung diseases or cancer. For more information, talk with your child's doctor.
For more information about the pneumococcal pneumonia vaccine, go to the Centers for Disease Control and Prevention's (CDC's) Vaccines and Preventable Diseases: Pneumococcal Vaccination Web page.
Influenza Vaccine
The vaccine that helps prevent the flu is good for 1 year. It's usually given in October or November, before peak flu season.
Because many people get pneumonia after having the flu, this vaccine also helps prevent pneumonia.
For more information about the influenza vaccine, go to the CDC's Vaccines and Preventable Diseases: Seasonal Influenza (Flu) Vaccination Web page.
Hib Vaccine
Haemophilus influenzae type b (Hib) is a type of bacteria that can cause pneumonia and meningitis (men-in-JI-tis). (Meningitis is an infection of the covering of the brain and spinal cord.) The Hib vaccine is given to children to help prevent these infections.
The vaccine is recommended for all children in the United States who are younger than 5 years old. The vaccine often is given to infants starting at 2 months of age.
For more information about the Hib vaccine, go to the CDC's Vaccines and Preventable Diseases: Hib Vaccination Web page.
Other Ways To Help Prevent Pneumonia
You also can take the following steps to help prevent pneumonia:
Wash your hands with soap and water or alcohol-based rubs to kill germs.
Don't smoke. Smoking damages your lungs' ability to filter out and defend against germs. For information about how to quit smoking, go to the Health Topics Smoking and Your Heart article. Although this resource focuses on heart health, it includes general information about how to quit smoking.
Keep your immune system strong. Get plenty of rest and physical activity and follow a healthy diet.
If you have pneumonia, limit contact with family and friends. Cover your nose and mouth while coughing or sneezing, and get rid of used tissues right away. These actions help keep the infection from spreading. </s> |

<s>[INST] Human: What are the genetic changes related to Cornelia de Lange syndrome ? [/INST] Assistant: Cornelia de Lange syndrome can result from mutations in at least five genes: NIPBL, SMC1A, HDAC8, RAD21, and SMC3. Mutations in the NIPBL gene have been identified in more than half of all people with this condition; mutations in the other genes are much less common. The proteins produced from all five genes contribute to the structure or function of the cohesin complex, a group of proteins with an important role in directing development before birth. Within cells, the cohesin complex helps regulate the structure and organization of chromosomes, stabilize cells' genetic information, and repair damaged DNA. The cohesin complex also regulates the activity of certain genes that guide the development of limbs, face, and other parts of the body. Mutations in the NIPBL, SMC1A, HDAC8, RAD21, and SMC3 genes cause Cornelia de Lange syndrome by impairing the function of the cohesin complex, which disrupts gene regulation during critical stages of early development. The features of Cornelia de Lange syndrome vary widely, and the severity of the disorder can differ even in individuals with the same gene mutation. Researchers suspect that additional genetic or environmental factors may be important for determining the specific signs and symptoms in each individual. In general, SMC1A, RAD21, and SMC3 gene mutations cause milder signs and symptoms than NIPBL gene mutations. Mutations in the HDAC8 gene cause a somewhat different set of features, including delayed closure of the "soft spot" on the head (the anterior fontanelle) in infancy, widely spaced eyes, and dental abnormalities. Like affected individuals with NIPBL gene mutations, those with HDAC8 gene mutations may have significant intellectual disability. In about 30 percent of cases, the cause of Cornelia de Lange syndrome is unknown. Researchers are looking for additional changes in the five known genes, as well as mutations in other genes, that may cause this condition. </s> |
<s>[INST] Human: What causes Prader-Willi syndrome ? [/INST] Assistant: What causes Prader-Willi syndrome? Prader-Willi syndrome (PWS) is caused by the loss of active genes in a specific region of chromosome 15. People normally inherit one copy of chromosome 15 from each parent. Some genes on chromosome 15 are only active (or "expressed") on the copy that is inherited from a person's father (the paternal copy). When genes are only active if inherited from a specific parent, it is called genomic imprinting. About 70% of cases of PWS occur when a person is missing specific genes on the long arm of the paternal copy of chromosome 15. This is called a deletion. While there are copies of these same genes on the maternal copy of chromosome 15, the maternal copies of these genes are not expressed. In about 25% of cases, PWS is due to a person inheriting only 2 maternal copies of chromosome 15, instead of one copy from each parent. This is called maternal uniparental disomy. Rarely (in about 2% of cases), PWS is caused by a rearrangement of chromosome material called a translocation, or by a change (mutation) or other defect that abnormally inactivates genes on the paternal chromosome 15. Each of these genetic changes result in a loss of gene function on part of chromosome 15, likely causing the characteristic features of PWS. </s> |
<s>[INST] Human: What is (are) malignant migrating partial seizures of infancy ? [/INST] Assistant: Malignant migrating partial seizures of infancy (MMPSI) is a severe form of epilepsy that begins very early in life. Recurrent seizures begin before the age of 6 months but commonly start within a few weeks of birth. The seizures do not respond well to treatment. Although affected individuals may develop normally at first, progression stalls and skills decline when seizures begin; as a result, affected individuals have profound developmental delay. The seizures in MMPSI are described as partial (or focal) because the seizure activity occurs in regions of the brain rather than affecting the entire brain. Seizure activity can appear in multiple locations in the brain or move (migrate) from one region to another during an episode. Depending on the region affected, seizures can involve sudden redness and warmth (flushing) of the face; drooling; short pauses in breathing (apnea); movement of the head or eyes to one side; twitches in the eyelids or tongue; chewing motions; or jerking of an arm, leg, or both on one side of the body. If seizure activity spreads to affect the entire brain, it causes a loss of consciousness, muscle stiffening, and rhythmic jerking (tonic-clonic seizure). Episodes that begin as partial seizures and spread throughout the brain are known as secondarily generalized seizures. Initially, the seizures associated with MMPSI are relatively infrequent, occurring every few weeks. Within a few months of the seizures starting, though, the frequency increases. Affected individuals can have clusters of five to 30 seizures several times a day. Each seizure typically lasts seconds to a couple of minutes, but they can be prolonged (classified as status epilepticus). In some cases, the seizure activity may be almost continuous for several days. After a year or more of persistent seizures, the episodes become less frequent. Seizures can affect growth of the brain and lead to a small head size (microcephaly). The problems with brain development can also cause profound developmental delay and intellectual impairment. Affected babies often lose the mental and motor skills they developed after birth, such as the ability to make eye contact and control their head movement. Many have weak muscle tone (hypotonia) and become "floppy." If seizures can be controlled for a short period, development may improve. Some affected children learn to reach for objects or walk. However, most children with this condition do not develop language skills. Because of the serious health problems caused by MMPSI, many affected individuals do not survive past infancy or early childhood. </s> |

<s>[INST] Human: What is (are) Thalassemias ? [/INST] Assistant: Thalassemias (thal-a-SE-me-ahs) are inherited blood disorders. "Inherited" means that the disorder is passed from parents to children through genes.
Thalassemias cause the body to make fewer healthy red blood cells and less hemoglobin (HEE-muh-glow-bin) than normal. Hemoglobin is an iron-rich protein in red blood cells. It carries oxygen to all parts of the body. Hemoglobin also carries carbon dioxide (a waste gas) from the body to the lungs, where it's exhaled.
People who have thalassemias can have mild or severe anemia (uh-NEE-me-uh). Anemia is caused by a lower than normal number of red blood cells or not enough hemoglobin in the red blood cells.
Overview
Normal hemoglobin, also called hemoglobin A, has four protein chainstwo alpha globin and two beta globin. The two major types of thalassemia, alpha and beta, are named after defects in these protein chains.
Four genes (two from each parent) are needed to make enough alpha globin protein chains. Alpha thalassemia trait occurs if one or two of the four genes are missing. If more than two genes are missing, moderate to severe anemia occurs.
The most severe form of alpha thalassemia is called alpha thalassemia major or hydrops fetalis. Babies who have this disorder usually die before or shortly after birth.
Two genes (one from each parent) are needed to make enough beta globin protein chains. Beta thalassemia occurs if one or both genes are altered.
The severity of beta thalassemia depends on how much one or both genes are affected. If both genes are affected, the result is moderate to severe anemia. The severe form of beta thalassemia is known as thalassemia major or Cooley's anemia.
Thalassemias affect males and females. The disorders occur most often among people of Italian, Greek, Middle Eastern, Southern Asian, and African descent. Severe forms usually are diagnosed in early childhood and are lifelong conditions.
Doctors diagnose thalassemias using blood tests. The disorders are treated with blood transfusions, medicines, and other procedures.
Outlook
Treatments for thalassemias have improved over the years. People who have moderate or severe thalassemias are now living longer and have better quality of life.
However, complications from thalassemias and their treatments are frequent. People who have moderate or severe thalassemias must closely follow their treatment plans. They need to take care of themselves to remain as healthy as possible. </s> |

<s>[INST] Human: What are the genetic changes related to Klinefelter syndrome ? [/INST] Assistant: Klinefelter syndrome is a condition related to the X and Y chromosomes (the sex chromosomes). People typically have two sex chromosomes in each cell: females have two X chromosomes (46,XX), and males have one X and one Y chromosome (46,XY). Most often, Klinefelter syndrome results from the presence of one extra copy of the X chromosome in each cell (47,XXY). Extra copies of genes on the X chromosome interfere with male sexual development, often preventing the testes from functioning normally and reducing the levels of testosterone. Most people with an extra X chromosome have the features described above, although some have few or no associated signs and symptoms. Some people with features of Klinefelter syndrome have more than one extra sex chromosome in each cell (for example, 48,XXXY or 49,XXXXY). These conditions, which are often called variants of Klinefelter syndrome, tend to cause more severe signs and symptoms than classic Klinefelter syndrome. In addition to affecting male sexual development, variants of Klinefelter syndrome are associated with intellectual disability, distinctive facial features, skeletal abnormalities, poor coordination, and severe problems with speech. As the number of extra sex chromosomes increases, so does the risk of these health problems. Some people with features of Klinefelter syndrome have the extra X chromosome in only some of their cells; in these individuals, the condition is described as mosaic Klinefelter syndrome (46,XY/47,XXY). Individuals with mosaic Klinefelter syndrome may have milder signs and symptoms, depending on how many cells have an additional X chromosome. </s> |

<s>[INST] Human: What are the symptoms of Asthma ? [/INST] Assistant: Common signs and symptoms of asthma include:
Coughing. Coughing from asthma often is worse at night or early in the morning, making it hard to sleep.
Wheezing. Wheezing is a whistling or squeaky sound that occurs when you breathe.
Chest tightness. This may feel like something is squeezing or sitting on your chest.
Shortness of breath. Some people who have asthma say they can't catch their breath or they feel out of breath. You may feel like you can't get air out of your lungs.
Not all people who have asthma have these symptoms. Likewise, having these symptoms doesn't always mean that you have asthma. The best way to diagnose asthma for certain is to use a lung function test, a medical history (including type and frequency of symptoms), and a physical exam.
The types of asthma symptoms you have, how often they occur, and how severe they are may vary over time. Sometimes your symptoms may just annoy you. Other times, they may be troublesome enough to limit your daily routine.
Severe symptoms can be fatal. It's important to treat symptoms when you first notice them so they don't become severe.
With proper treatment, most people who have asthma can expect to have few, if any, symptoms either during the day or at night.
What Causes Asthma Symptoms To Occur?
Many things can trigger or worsen asthma symptoms. Your doctor will help you find out which things (sometimes called triggers) may cause your asthma to flare up if you come in contact with them. Triggers may include:
Allergens from dust, animal fur, cockroaches, mold, and pollens from trees, grasses, and flowers
Irritants such as cigarette smoke, air pollution, chemicals or dust in the workplace, compounds in home dcor products, and sprays (such as hairspray)
Medicines such as aspirin or other nonsteroidal anti-inflammatory drugs and nonselective beta-blockers
Sulfites in foods and drinks
Viral upper respiratory infections, such as colds
Physical activity, including exercise
Other health conditions can make asthma harder to manage. Examples of these conditions include a runny nose, sinus infections, reflux disease, psychological stress, and sleep apnea. These conditions need treatment as part of an overall asthma care plan.

<s>[INST] Human: What is (are) Varicose Veins ? [/INST] Assistant: Varicose veins are swollen, twisted veins that you can see just under the skin. They usually occur in the legs, but also can form in other parts of the body. Hemorrhoids are a type of varicose vein. Your veins have one-way valves that help keep blood flowing toward your heart. If the valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell, which can lead to varicose veins. Varicose veins are very common. You are more at risk if you are older, a female, obese, don't exercise or have a family history. They can also be more common in pregnancy. Doctors often diagnose varicose veins from a physical exam. Sometimes you may need additional tests. Exercising, losing weight, elevating your legs when resting, and not crossing them when sitting can help keep varicose veins from getting worse. Wearing loose clothing and avoiding long periods of standing can also help. If varicose veins are painful or you don't like the way they look, your doctor may recommend procedures to remove them.

<s>[INST] Human: What to do for Hypoglycemia ? [/INST] Assistant: Two types of hypoglycemia can occur in people who do not have diabetes:
- Reactive hypoglycemia, also called postprandial hypoglycemia, occurs within 4 hours after meals. - Fasting hypoglycemia, also called postabsorptive hypoglycemia, is often related to an underlying disease.
Symptoms of both reactive and fasting hypoglycemia are similar to diabetes-related hypoglycemia. Symptoms may include hunger, sweating, shakiness, dizziness, light-headedness, sleepiness, confusion, difficulty speaking, anxiety, and weakness.
To find the cause of a patient's hypoglycemia, the doctor will use laboratory tests to measure blood glucose, insulin, and other chemicals that play a part in the body's use of energy.
Reactive Hypoglycemia
Diagnosis
To diagnose reactive hypoglycemia, the doctor may
- ask about signs and symptoms - test blood glucose while the patient is having symptoms by taking a blood sample from the arm and sending it to a laboratory for analysis* - check to see whether the symptoms ease after the patient's blood glucose returns to 70 mg/dL or above after eating or drinking
A blood glucose level below 70 mg/dL at the time of symptoms and relief after eating will confirm the diagnosis. The oral glucose tolerance test is no longer used to diagnose reactive hypoglycemia because experts now know the test can actually trigger hypoglycemic symptoms.
Causes and Treatment
The causes of most cases of reactive hypoglycemia are still open to debate. Some researchers suggest that certain people may be more sensitive to the body's normal release of the hormone epinephrine, which causes many of the symptoms of hypoglycemia. Others believe deficiencies in glucagon secretion might lead to reactive hypoglycemia.
A few causes of reactive hypoglycemia are certain, but they are uncommon. Gastricor stomachsurgery can cause reactive hypoglycemia because of the rapid passage of food into the small intestine. Rare enzyme deficiencies diagnosed early in life, such as hereditary fructose intolerance, also may cause reactive hypoglycemia.
To relieve reactive hypoglycemia, some health professionals recommend
- eating small meals and snacks about every 3 hours - being physically active - eating a variety of foods, including meat, poultry, fish, or nonmeat sources of protein; starchy foods such as whole-grain bread, rice, and potatoes; fruits; vegetables; and dairy products - eating foods high in fiber - avoiding or limiting foods high in sugar, especially on an empty stomach
The doctor can refer patients to a registered dietitian for personalized meal planning advice. Although some health professionals recommend a diet high in protein and low in carbohydrates, studies have not proven the effectiveness of this kind of diet to treat reactive hypoglycemia.
Fasting Hypoglycemia
Diagnosis
Fasting hypoglycemia is diagnosed from a blood sample that shows a blood glucose level below 50 mg/dL after an overnight fast, between meals, or after physical activity.
Causes and Treatment
Causes of fasting hypoglycemia include certain medications, alcoholic beverages, critical illnesses, hormonal deficiencies, some kinds of tumors, and certain conditions occurring in infancy and childhood.
Medications. Medications, including some used to treat diabetes, are the most common cause of hypoglycemia. Other medications that can cause hypoglycemia include
- salicylates, including aspirin, when taken in large doses - sulfa medications, which are used to treat bacterial infections - pentamidine, which treats a serious kind of pneumonia - quinine, which is used to treat malaria
If using any of these medications causes a person's blood glucose level to fall, the doctor may advise stopping the medication or changing the dose.
Alcoholic beverages. Drinking alcoholic beverages, especially binge drinking, can cause hypoglycemia. The body's breakdown of alcohol interferes with the liver's efforts to raise blood glucose. Hypoglycemia caused by excessive drinking can be serious and even fatal.
Critical illnesses. Some illnesses that affect the liver, heart, or kidneys can cause hypoglycemia. Sepsis, which is an overwhelming infection, and starvation are other causes of hypoglycemia. In these cases, treating the illness or other underlying cause will correct the hypoglycemia.
Hormonal deficiencies. Hormonal deficiencies may cause hypoglycemia in very young children, but rarely in adults. Shortages of cortisol, growth hormone, glucagon, or epinephrine can lead to fasting hypoglycemia. Laboratory tests for hormone levels will determine a diagnosis and treatment. Hormone replacement therapy may be advised.
Tumors. Insulinomas are insulin-producing tumors in the pancreas. Insulinomas can cause hypoglycemia by raising insulin levels too high in relation to the blood glucose level. These tumors are rare and do not normally spread to other parts of the body. Laboratory tests can pinpoint the exact cause. Treatment involves both short-term steps to correct the hypoglycemia and medical or surgical measures to remove the tumor.
Conditions occurring in infancy and childhood. Children rarely develop hypoglycemia. If they do, causes may include the following:
- Brief intolerance to fasting, often during an illness that disturbs regular eating patterns. Children usually outgrow this tendency by age 10. - Hyperinsulinism, which is the overproduction of insulin. This condition can result in temporary hypoglycemia in newborns, which is common in infants of mothers with diabetes. Persistent hyperinsulinism in infants or children is a complex disorder that requires prompt evaluation and treatment by a specialist. - Enzyme deficiencies that affect carbohydrate metabolism. These deficiencies can interfere with the body's ability to process natural sugars, such as fructose and galactose, glycogen, or other metabolites. - Hormonal deficiencies such as lack of pituitary or adrenal hormones.
*A personal blood glucose monitor cannot be used to diagnose reactive hypoglycemia. </s> |
<s>[INST] Human: Is autoimmune lymphoproliferative syndrome inherited ? [/INST] Assistant: In most people with ALPS, including the majority of those with FAS gene mutations, this condition is inherited in an autosomal dominant pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. In these cases, an affected person usually inherits the mutation from one affected parent. Other cases with an autosomal dominant pattern result from new (de novo) gene mutations that occur early in embryonic development in people with no history of the disorder in their family. In a small number of cases, including some cases caused by FAS gene mutations, ALPS is inherited in an autosomal recessive pattern, which means both copies of a gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. ALPS can also arise from a mutation in lymphocytes that is not inherited but instead occurs during an individual's lifetime. This alteration is called a somatic mutation. </s> |

<s>[INST] Human: What is (are) mitochondrial membrane protein-associated neurodegeneration ? [/INST] Assistant: Mitochondrial membrane protein-associated neurodegeneration (MPAN) is a disorder of the nervous system. The condition typically begins in childhood or early adulthood and worsens (progresses) over time. MPAN commonly begins with difficulty walking. As the condition progresses, affected individuals usually develop other movement problems, including muscle stiffness (spasticity) and involuntary muscle cramping (dystonia). Many people with MPAN have a pattern of movement abnormalities known as parkinsonism. These abnormalities include unusually slow movement (bradykinesia), muscle rigidity, involuntary trembling (tremors), and an inability to hold the body upright and balanced (postural instability). Other neurological problems that occur in individuals with MPAN include degeneration of the nerve cells that carry visual information from the eyes to the brain (optic atrophy), which can impair vision; problems with speech (dysarthria); difficulty swallowing (dysphagia); and, in later stages of the condition, an inability to control the bowels or the flow of urine (incontinence). Additionally, affected individuals may experience a loss of intellectual function (dementia) and psychiatric symptoms such as behavioral problems, mood swings, hyperactivity, and depression. MPAN is characterized by an abnormal buildup of iron in certain regions of the brain. Because of these deposits, MPAN is considered part of a group of conditions known as neurodegeneration with brain iron accumulation (NBIA). </s> |

<s>[INST] Human: What are the genetic changes related to Mowat-Wilson syndrome ? [/INST] Assistant: Mutations in the ZEB2 gene cause Mowat-Wilson syndrome. The ZEB2 gene provides instructions for making a protein that plays a critical role in the formation of many organs and tissues before birth. This protein is a transcription factor, which means that it attaches (binds) to specific regions of DNA and helps control the activity of particular genes. Researchers believe that the ZEB2 protein is involved in the development of tissues that give rise to the nervous system, digestive tract, facial features, heart, and other organs. Mowat-Wilson syndrome almost always results from a loss of one working copy of the ZEB2 gene in each cell. In some cases, the entire gene is deleted. In other cases, mutations within the gene lead to the production of an abnormally short, nonfunctional version of the ZEB2 protein. A shortage of this protein disrupts the normal development of many organs and tissues, which causes the varied signs and symptoms of Mowat-Wilson syndrome. </s> |

<s>[INST] Human: What is (are) Valley Fever ? [/INST] Assistant: Valley Fever is a disease caused by a fungus (or mold) called Coccidioides. The fungi live in the soil of dry areas like the southwestern U.S. You get it from inhaling the spores of the fungus. The infection cannot spread from person to person. Anyone can get Valley Fever. But it's most common among older adults, especially those 60 and older. People who have recently moved to an area where it occurs are at highest risk for infection. Other people at higher risk include - Workers in jobs that expose them to soil dust. These include construction workers, agricultural workers, and military forces doing field training. - African Americans and Asians - Women in their third trimester of pregnancy - People with weak immune systems Valley Fever is often mild, with no symptoms. If you have symptoms, they may include a flu-like illness, with fever, cough, headache, rash, and muscle aches. Most people get better within several weeks or months. A small number of people may develop a chronic lung or widespread infection. Valley Fever is diagnosed by testing your blood, other body fluids, or tissues. Many people with the acute infection get better without treatment. In some cases, doctors may prescribe antifungal drugs for acute infections. Severe infections require antifungal drugs.

<s>[INST] Human: What to do for Intestinal Pseudo-obstruction ? [/INST] Assistant: - Intestinal pseudo-obstruction is a rare condition with symptoms that resemble those caused by a blockage, or obstruction, of the intestines, also called the bowel. However, when a health care provider examines the intestines, no blockage exists. Instead, the symptoms are due to nerve or muscle problems that affect the movement of food, fluid, and air through the intestines. - Intestinal pseudo-obstruction symptoms may include abdominal swelling or bloating, also called distension; abdominal pain; nausea; vomiting; constipation; and diarrhea. Over time, the condition can cause malnutrition, bacterial overgrowth in the intestines, and weight loss. - To diagnose intestinal pseudo-obstruction, a health care provider may suggest the person consult a gastroenterologista doctor who specializes in digestive diseases. A health care provider will perform a physical exam; take a complete medical history, imaging studies, and a biopsy; and perform blood tests. A health care provider may order other tests to confirm the diagnosis. - A health care provider will treat intestinal pseudo-obstruction with nutritional support, medications, and, in some cases, decompression. Rarely, a person will need surgery. If an illness, a medication, or both cause intestinal pseudo-obstruction, a health care provider will treat the underlying illness, stop the medication, or do both.

<s>[INST] Human: What is (are) Dowling-Degos disease ? [/INST] Assistant: Dowling-Degos disease is a skin condition characterized by a lacy or net-like (reticulate) pattern of abnormally dark skin coloring (hyperpigmentation), particularly in the body's folds and creases. These skin changes typically first appear in the armpits and groin area and can later spread to other skin folds such as the crook of the elbow and back of the knee. Less commonly, pigmentation changes can also occur on the wrist, back of the hand, face, scalp, scrotum (in males), and vulva (in females). These areas of hyperpigmentation do not darken with exposure to sunlight and cause no health problems. Individuals with Dowling-Degos disease may also have dark lesions on the face and back that resemble blackheads, red bumps around the mouth that resemble acne, or depressed or pitted scars on the face similar to acne scars but with no history of acne. Cysts within the hair follicle (pilar cysts) may develop, most commonly on the scalp. Rarely, affected individuals have patches of skin that are unusually light in color (hypopigmented). The pigmentation changes characteristic of Dowling-Degos disease typically begin in late childhood or in adolescence, although in some individuals, features of the condition do not appear until adulthood. New areas of hyperpigmentation tend to develop over time, and the other skin lesions tend to increase in number as well. While the skin changes caused by Dowling-Degos disease can be bothersome, they typically cause no health problems. A condition called Galli-Galli disease has signs and symptoms similar to those of Dowling-Degos disease. In addition to pigmentation changes, individuals with Galli-Galli disease also have a breakdown of cells in the outer layer of skin (acantholysis). Acantholysis can cause skin irritation and itchiness. These conditions used to be considered two separate disorders, but Galli-Galli disease and Dowling-Degos disease are now regarded as the same condition. </s> |

<s>[INST] Human: What are the genetic changes related to hypomagnesemia with secondary hypocalcemia ? [/INST] Assistant: Hypomagnesemia with secondary hypocalcemia is caused by mutations in the TRPM6 gene. This gene provides instructions for making a protein that acts as a channel, which allows charged atoms (ions) of magnesium (Mg2+) to flow into cells; the channel may also allow small amounts of calcium ions (Ca2+) to pass into cells. Magnesium is involved in many cell processes, including production of cellular energy, maintenance of DNA building blocks (nucleotides), protein production, and cell growth and death. Magnesium and calcium are also required for the normal functioning of nerve cells that control muscle movement (motor neurons). The TRPM6 channel is embedded in the membrane of epithelial cells that line the large intestine, structures in the kidneys known as distal convoluted tubules, the lungs, and the testes in males. When the body needs additional Mg2+, the TRPM6 channel allows it to be absorbed in the intestine and filtered from the fluids that pass through the kidneys by the distal convoluted tubules. When the body has sufficient or too much Mg2+, the TRPM6 channel does not filter out the Mg2+ from fluids but allows the ion to be released from the kidney cells into the urine. The channel also helps to regulate Ca2+, but to a lesser degree. Most TRPM6 gene mutations that cause hypomagnesemia with secondary hypocalcemia result in a lack of functional protein. A loss of functional TRPM6 channels prevent Mg2+ absorption in the intestine and cause excessive amounts of Mg2+ to be excreted by the kidneys and released in the urine. A lack of Mg2+ in the body impairs the production of parathyroid hormone, which likely reduces blood Ca2+ levels. Additionally, hypomagnesemia and hypocalcemia can disrupt many cell processes and impair the function of motor neurons, leading to neurological problems and movement disorders. If the condition is not effectively treated and low Mg2+ levels persist, signs and symptoms can worsen over time and may lead to early death. </s> |

<s>[INST] Human: What is (are) phosphoglycerate dehydrogenase deficiency ? [/INST] Assistant: Phosphoglycerate dehydrogenase deficiency is a condition characterized by an unusually small head size (microcephaly); impaired development of physical reactions, movements, and speech (psychomotor retardation); and recurrent seizures (epilepsy). Different types of phosphoglycerate dehydrogenase deficiency have been described; they are distinguished by their severity and the age at which symptoms first begin. Most affected individuals have the infantile form, which is the most severe form, and are affected from infancy. Symptoms of the juvenile and adult types appear later in life; these types are very rare. In phosphoglycerate dehydrogenase deficiency there is a progressive loss of brain cells leading to a loss of brain tissue (brain atrophy), specifically affecting the fatty tissue known as myelin that surrounds nerve cells (hypomyelination). Frequently, the tissue that connects the two halves of the brain (corpus callosum) is small and thin, and the fluid-filled cavities (ventricles) near the center of the brain are enlarged. Because development of the brain is disrupted, the head does not grow at the same rate as the body, so it appears that the head is getting smaller as the body grows (progressive microcephaly). Poor brain growth leads to an inability to achieve many developmental milestones such as sitting unsupported and speaking. Many affected infants also have difficulty feeding. The seizures in phosphoglycerate dehydrogenase deficiency can vary in type. Recurrent muscle contractions called infantile spasms are typical early in the disorder. Without early treatment, seizures may progress to tonic-clonic seizures, which involve a loss of consciousness, muscle rigidity, and convulsions; myoclonic seizures, which involve rapid, uncontrolled muscle jerks; or drop attacks, which are sudden episodes of weak muscle tone. Individuals with the infantile form of phosphoglycerate dehydrogenase deficiency develop many of the features described above. Individuals with the juvenile form typically have epilepsy as well as mild developmental delay and intellectual disability. Only one case of the adult form has been reported; signs and symptoms began in mid-adulthood and included mild intellectual disability; difficulty coordinating movements (ataxia); and numbness, tingling, and pain in the arms and legs (sensory neuropathy). </s> |

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. </s> |
<s>[INST] Human: What is the outlook for Childhood Craniopharyngioma ? [/INST] Assistant: Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - The size of the tumor. - Where the tumor is in the brain. - Whether there are tumor cells left after surgery. - The child's age. - Side effects that may occur months or years after treatment. - Whether the tumor has just been diagnosed or has recurred (come back). </s> |
<s>[INST] Human: What are the genetic changes related to Krabbe disease ? [/INST] Assistant: Mutations in the GALC gene cause Krabbe disease. These mutations cause a deficiency of the enzyme galactosylceramidase. This deficiency leads to a progressive loss of myelin that covers many nerves. Without myelin, nerves in the brain and other parts of the body cannot function properly, leading to the signs and symptoms of Krabbe disease. </s> |
<s>[INST] Human: What are the symptoms of Chronic Fatigue Syndrome (CFS) ? [/INST] Assistant: Chronic fatigue syndrome can be misdiagnosed or overlooked because its symptoms are similar to so many other illnesses. Fatigue, for instance, can be a symptom for hundreds of illnesses. Looking closer at the nature of the symptoms though, can help a doctor distinguish CFS from other illnesses.
Primary Symptoms
As the name chronic fatigue syndrome suggests, fatigue is one part of this illness. With CFS, however, the fatigue is accompanied by other symptoms. In addition, the fatigue is not the kind you might feel after a particularly busy day or week, after a sleepless night, or after a single stressful event. It's a severe, incapacitating fatigue that isn't improved by bed rest and that is often worsened by physical activity or mental exertion. It's an all-encompassing fatigue that can dramatically reduce a person's activity level and stamina.
People with CFS function at a significantly lower level of activity than they were capable of before they became ill. The illness results in a substantial reduction in work-related, personal, social, and educational activities.
The fatigue of CFS is accompanied by characteristic illness symptoms lasting at least 6 months. These symptoms include:
- increased malaise (extreme exhaustion and sickness) following physical activity or mental exertion
- problems with sleep
- difficulties with memory and concentration
- persistent muscle pain
- joint pain (without redness or swelling)
- headache
- tender lymph nodes in the neck or armpit
- sore throat
Other Symptoms
The symptoms listed above are the symptoms used to diagnose CFS. However, many CFS patients and patients in general may experience other symptoms, including:
- brain fog (feeling like you're in a mental fog)
- difficulty maintaining an upright position, dizziness, balance problems or fainting
- allergies or sensitivities to foods, odors, chemicals, medications, or noise
- irritable bowel
- chills and night sweats
- visual disturbances (sensitivity to light, blurring, eye pain)
- depression or mood problems (irritability, mood swings, anxiety, panic attacks)
It's important to tell your health care professional if you're experiencing any of these symptoms. You might have CFS, or you might have another treatable disorder. Only a health care professional can diagnose CFS.
What's the Clinical Course of CFS?
The severity of CFS varies from patient to patient. Some people can maintain fairly active lives. For most patients, however, CFS significantly limits their work, school, and family activities for periods of time.
While symptoms vary from person to person in number, type, and severity, all CFS patients are limited in what they can do to some degree. CDC studies show that CFS can be as disabling as multiple sclerosis, lupus, rheumatoid arthritis, heart disease, end-stage renal disease, chronic obstructive pulmonary disease (COPD), and similar chronic conditions.
CFS often affects patients in cycles: Patients will have periods of illness followed by periods of relative well-being. For some patients, symptoms may diminish or even go into complete remission; however, they often recur at a later point in time. This pattern of remission and relapse makes CFS especially hard for patients to manage. Patients who are in remission may be tempted to overdo activities when they're feeling better, but this overexertion may actually contribute to a relapse.
The percentage of CFS patients who recover is unknown, but there is some evidence to indicate that patients benefit when accompanying conditions are identified and treated and when symptoms are managed. High-quality health care is important. </s> |
<s>[INST] Human: what research (or clinical trials) is being done for Lip and Oral Cavity Cancer ? [/INST] Assistant: New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. Hyperfractionated radiation therapy Hyperfractionated radiation therapy is radiation treatment in which the total dose of radiation is divided into small doses and the treatments are given more than once a day. Hyperthermia therapy Hyperthermia therapy is a treatment in which body tissue is heated above normal temperature to damage and kill cancer cells or to make cancer cells more sensitive to the effects of radiation and certain anticancer drugs.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. </s> |

<s>[INST] Human: What is (are) Neuroleptic malignant syndrome ? [/INST] Assistant: Neuroleptic malignant syndrome is a rare neurological condition that is caused by an adverse reaction to neuroleptic (tranquilizer) or antipsychotic drugs. These drugs are commonly prescribed for the treatment of schizophrenia and other neurological, mental, or emotional disorders. Affected people may experience high fever, muscle stiffness, sweating, unstable blood pressure, altered mental status, and autonomic dysfunction. In most cases, the condition develops within the first 2 weeks of treatment with the drug; however, it may develop any time during the therapy period. The exact underlying cause of neuroleptic malignant syndrome is unknown. In some cases, more than one family member can be affected which suggests there may be a genetic component. Upon diagnosis of the condition, the neuroleptic or antipsychotic drug is generally discontinued under a physician's supervision. Medications and/or other interventions may also be recommended to manage symptoms. </s> |

<s>[INST] Human: What is (are) Focal dystonia ? [/INST] Assistant: Focal dystonia is a movement disorder that is localized to a specific part of the body. The dystonias are a group of movement problems characterized by involuntary, sustained muscle contractions, tremors, and other uncontrolled movements. Focal task-specific dystonia, or FTSD, interferes with the performance of particular tasks, such as writing, playing a musical instrument, or participating in a sport. Additionally, FTSD has been reported in tailors, shoemakers, hair stylists, and people who frequently type or use a computer mouse. While the abnormal movements associated with focal dystonia are usually painless, they can cause high levels of anxiety. The causes of focal dystonia are unknown, although the disorder likely results from a combination of genetic and environmental factors. It is possible that the different forms of FTSD have different underlying causes. Researchers have found that at least some cases are related to malfunction of the basal ganglia, which are structures deep within the brain that help start and control movement. Most cases of focal dystonia are sporadic, which means they occur in people with no history of the condition in their family. However, at least 10 percent of affected individuals have a family history which seems to follow an autosomal dominant pattern of inheritance. </s> |
<s>[INST] Human: Is gray platelet syndrome inherited ? [/INST] Assistant: When gray platelet syndrome is caused by NBEAL2 gene mutations, it has an autosomal recessive pattern of inheritance, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the altered gene in each cell. Gray platelet syndrome can also be inherited in an autosomal dominant pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. An affected person often inherits the condition from one affected parent. Researchers are working to determine which gene or genes are associated with the autosomal dominant form of gray platelet syndrome. </s> |
