What is (are) Gamma heavy chain disease ? | Gamma heavy chain disease is characterized by the abnormal production of antibodies. Antibodies are made up of light chains and heavy chains. In this disorder, the heavy chain of the gamma antibody (IgG) is overproduced by the body. Gamma heavy chain disease mainly affects older adults and is similar to aggressive malignant (cancerous) lymphoma. However, some people with this disorder have no symptoms. People with symptoms may respond to chemotherapy drugs, corticosteroids, and radiation therapy. Approximately one-third of individuals with gamma heavy chain disease are also diagnosed with an autoimmune disorder. | 112,856 |

what research (or clinical trials) is being done for Guillain-Barr Syndrome ? | Scientists are concentrating on finding new treatments and refining existing ones. Scientists are also looking at the workings of the immune system to find which cells are responsible for beginning and carrying out the attack on the nervous system. The fact that so many cases of Guillain-Barr begin after a viral or bacterial infection suggests that certain characteristics of some viruses and bacteria may activate the immune system inappropriately. Investigators are searching for those characteristics. Neurological scientists, immunologists, virologists, and pharmacologists are all working collaboratively to learn how to prevent this disorder and to make better therapies available when it strikes. | 88,726 |

What are the treatments for Mosaic trisomy 9 ? | How might mosaic trisomy 9 be treated? Because mosaic trisomy 9 affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this condition varies based on the signs and symptoms present in each person. For example, children with bone or muscle abnormalities and/or delayed motor milestones (i.e. walking) may be referred for physical or occupational therapy. Depending on the degree of intellectual disability, a child may require special education classes. Heart defects and cleft lip and/or palate may need to be surgically repaired. Children with hydrocephalus may be treated with certain medications and/or shunting (placement of a specialized device that drains excess fluid away from the brain). Other surgeries may be recommended depending on the nature and severity of the other features (i.e. craniofacial, muscular, skeletal, kidney, and/or reproductive system problems) and their associated symptoms. | 114,352 |
What is (are) Digestive Diseases ? | When you eat, your body breaks food down to a form it can use to build and nourish cells and provide energy. This process is called digestion. Your digestive system is a series of hollow organs joined in a long, twisting tube. It runs from your mouth to your anus and includes your esophagus, stomach, and small and large intestines. Your liver, gallbladder and pancreas are also involved. They produce juices to help digestion. There are many types of digestive disorders. The symptoms vary widely depending on the problem. In general, you should see your doctor if you have - Blood in your stool - Changes in bowel habits - Severe abdominal pain - Unintentional weight loss - Heartburn not relieved by antacids NIH: National Institute of Diabetes and Digestive and Kidney Diseases | 117,474 |

Do you have information about Understanding Medical Research | Summary : It seems to happen almost every day - you hear about the results of a new medical research study. Sometimes the results of one study seem to disagree with the results of another study. It's important to be critical when reading or listening to reports of new medical findings. Some questions that can help you evaluate health information include: - Was the study in animals or people? - Does the study include people like you? - How big was the study? - Was it a randomized controlled clinical trial? - Where was the research done? - If a new treatment was being tested, were there side effects? - Who paid for the research? - Who is reporting the results?

What is (are) Adrenal Insufficiency and Addison's Disease ? | Adrenal insufficiency is an endocrine, or hormonal, disorder that occurs when the adrenal glands do not produce enough of certain hormones. The adrenal glands are located just above the kidneys.
Adrenal insufficiency can be primary or secondary. Addisons disease, the common term for primary adrenal insufficiency, occurs when the adrenal glands are damaged and cannot produce enough of the adrenal hormone cortisol. The adrenal hormone aldosterone may also be lacking. Addisons disease affects 110 to 144 of every 1 million people in developed countries.1
Secondary adrenal insufficiency occurs when the pituitary glanda pea-sized gland at the base of the brainfails to produce enough adrenocorticotropin (ACTH), a hormone that stimulates the adrenal glands to produce the hormone cortisol. If ACTH output is too low, cortisol production drops. Eventually, the adrenal glands can shrink due to lack of ACTH stimulation. Secondary adrenal insufficiency is much more common than Addisons disease.

What is (are) Snyder-Robinson syndrome ? | Snyder-Robinson syndrome is a condition characterized by intellectual disability, muscle and bone abnormalities, and other problems with development. It occurs exclusively in males. Males with Snyder-Robinson syndrome have delayed development and intellectual disability beginning in early childhood. The intellectual disability can range from mild to profound. Speech often develops late, and speech difficulties are common. Some affected individuals never develop any speech. Most affected males are thin and have low muscle mass, a body type described as an asthenic habitus. Weakness or "floppiness" (hypotonia) typically becomes apparent in infancy, and the loss of muscle tissue continues with age. People with this condition often have difficulty walking; most have an unsteady gait. Snyder-Robinson syndrome causes skeletal problems, particularly thinning of the bones (osteoporosis) that starts in early childhood. Osteoporosis causes the bones to be brittle and to break easily, often during normal activities. In people with Snyder-Robinson syndrome, broken bones occur most often in the arms and legs. Most affected individuals also develop an abnormal side-to-side and back-to-front curvature of the spine (scoliosis and kyphosis, often called kyphoscoliosis when they occur together). Affected individuals tend to be shorter than their peers and others in their family. Snyder-Robinson syndrome is associated with distinctive facial features, including a prominent lower lip; a high, narrow roof of the mouth or an opening in the roof of the mouth (a cleft palate); and differences in the size and shape of the right and left sides of the face (facial asymmetry). Other signs and symptoms that have been reported include seizures that begin in childhood and abnormalities of the genitalia and kidneys. | 105,891 |

What causes Urinary Retention ? | Urinary retention can result from
- obstruction of the urethra - nerve problems - medications - weakened bladder muscles
Obstruction of the Urethra
Obstruction of the urethra causes urinary retention by blocking the normal urine flow out of the body. Conditions such as benign prostatic hyperplasiaalso called BPHurethral stricture, urinary tract stones, cystocele, rectocele, constipation, and certain tumors and cancers can cause an obstruction.
Benign prostatic hyperplasia. For men in their 50s and 60s, urinary retention is often caused by prostate enlargement due to benign prostatic hyperplasia. Benign prostatic hyperplasia is a medical condition in which the prostate gland is enlarged and not cancerous. The prostate is a walnut-shaped gland that is part of the male reproductive system. The gland surrounds the urethra at the neck of the bladder. The bladder neck is the area where the urethra joins the bladder. The prostate goes through two main periods of growth. The first occurs early in puberty, when the prostate doubles in size. The second phase of growth begins around age 25 and continues during most of a mans life. Benign prostatic hyperplasia often occurs with the second phase of growth.
As the prostate enlarges, the gland presses against and pinches the urethra. The bladder wall becomes thicker. Eventually, the bladder may weaken and lose the ability to empty completely, leaving some urine in the bladder.
More information is provided in the NIDDK health topic, Prostate Enlargement: Benign Prostatic Hyperplasia.
Urethral stricture. A urethral stricture is a narrowing or closure of the urethra. Causes of urethral stricture include inflammation and scar tissue from surgery, disease, recurring UTIs, or injury. In men, a urethral stricture may result from prostatitis, scarring after an injury to the penis or perineum, or surgery for benign prostatic hyperplasia and prostate cancer. Prostatitis is a frequently painful condition that involves inflammation of the prostate and sometimes the areas around the prostate. The perineum is the area between the anus and the sex organs. Since men have a longer urethra than women, urethral stricture is more common in men than women.1
More information is provided in the NIDDK health topic, Prostatitis: Inflammation of the Prostate.
Surgery to correct pelvic organ prolapse, such as cystocele and rectocele, and urinary incontinence can also cause urethral stricture. The urethral stricture often gets better a few weeks after surgery.
Urethral stricture and acute or chronic urinary retention may occur when the muscles surrounding the urethra do not relax. This condition happens mostly in women.
Urinary tract stones. Urinary tract stones develop from crystals that form in the urine and build up on the inner surfaces of the kidneys, ureters, or bladder. The stones formed or lodged in the bladder may block the opening to the urethra.
Cystocele. A cystocele is a bulging of the bladder into the vagina. A cystocele occurs when the muscles and supportive tissues between a womans bladder and vagina weaken and stretch, letting the bladder sag from its normal position and bulge into the vagina. The abnormal position of the bladder may cause it to press against and pinch the urethra.
More information is provided in the NIDDK health topic, Cystocele.
Rectocele. A rectocele is a bulging of the rectum into the vagina. A rectocele occurs when the muscles and supportive tissues between a womans rectum and vagina weaken and stretch, letting the rectum sag from its normal position and bulge into the vagina. The abnormal position of the rectum may cause it to press against and pinch the urethra.
Constipation. Constipation is a condition in which a person has fewer than three bowel movements a week or has bowel movements with stools that are hard, dry, and small, making them painful or difficult to pass. A person with constipation may feel bloated or have pain in the abdomen the area between the chest and hips. Some people with constipation often have to strain to have a bowel movement. Hard stools in the rectum may push against the bladder and urethra, causing the urethra to be pinched, especially if a rectocele is present.
More information is provided in the NIDDK health topic, Constipation.
Tumors and cancers. Tumors and cancerous tissues in the bladder or urethra can gradually expand and obstruct urine flow by pressing against and pinching the urethra or by blocking the bladder outlet. Tumors may be cancerous or noncancerous.
Nerve Problems
Urinary retention can result from problems with the nerves that control the bladder and sphincters. Many events or conditions can interfere with nerve signals between the brain and the bladder and sphincters. If the nerves are damaged, the brain may not get the signal that the bladder is full. Even when a person has a full bladder, the bladder muscles that squeeze urine out may not get the signal to push, or the sphincters may not get the signal to relax. People of all ages can have nerve problems that interfere with bladder function. Some of the most common causes of nerve problems include
- vaginal childbirth - brain or spinal cord infections or injuries - diabetes - stroke - multiple sclerosis - pelvic injury or trauma - heavy metal poisoning
In addition, some children are born with defects that affect the coordination of nerve signals among the bladder, spinal cord, and brain. Spina bifida and other birth defects that affect the spinal cord can lead to urinary retention in newborns.
More information is provided in the NIDDK health topics, Nerve Disease and Bladder Control and Urine Blockage in Newborns.
Many patients have urinary retention right after surgery. During surgery, anesthesia is often used to block pain signals in the nerves, and fluid is given intravenously to compensate for possible blood loss. The combination of anesthesia and intravenous (IV) fluid may result in a full bladder with impaired nerve function, causing urinary retention. Normal bladder nerve function usually returns once anesthesia wears off. The patient will then be able to empty the bladder completely.
Medications
Various classes of medications can cause urinary retention by interfering with nerve signals to the bladder and prostate. These medications include
- antihistamines to treat allergies - cetirizine (Zyrtec) - chlorpheniramine (Chlor-Trimeton) - diphenhydramine (Benadryl) - fexofenadine (Allegra) - anticholinergics/antispasmodics to treat stomach cramps, muscle spasms, and urinary incontinence - hyoscyamine (Levbid) - oxybutynin (Ditropan) - propantheline (Pro-Banthine) - tolterodine (Detrol) - tricyclic antidepressants to treat anxiety and depression - amitriptyline (Elavil) - doxepin (Adapin) - imipramine (Tofranil) - nortriptyline (Pamelor)
Other medications associated with urinary retention include
- decongestants - ephedrine - phenylephrine - pseudoephedrine - nifedipine (Procardia), a medication to treat high blood pressure and chest pain - carbamazepine (Tegretol), a medication to control seizures in people with epilepsy - cyclobenzaprine (Flexeril), a muscle relaxant medication - diazepam (Valium), a medication used to relieve anxiety, muscle spasms, and seizures - nonsteroidal anti-inflammatory drugs - amphetamines - opioid analgesics
Over-the-counter cold and allergy medications that contain decongestants, such as pseudoephedrine, and antihistamines, such as diphenhydramine, can increase symptoms of urinary retention in men with prostate enlargement.
Weakened Bladder Muscles
Aging is a common cause of weakened bladder muscles. Weakened bladder muscles may not contract strongly enough or long enough to empty the bladder completely, resulting in urinary retention. | 89,588 |

What is (are) Congenital lobar emphysema ? | Congenital lobar emphysema is a rare respiratory disorder in which air can enter the lungs but cannot escape, causing overinflation (hyperinflation) of the lobes of the lung. It is most often detected in newborns or young infants, but some cases do not become apparent until adulthood. Signs and symptoms may include difficulty breathing and respiratory distress in infancy, an enlarged chest, compressed lung tissue, cyanosis, and underdevelopment of the cartilage that supports the bronchial tube (bronchial hypoplasia). This disorder may be severe enough to cause associated heart problems (15% of cases) or so mild as to never become apparent. Some cases may be caused by autosomal dominant inheritance while others occur for no apparent reason (sporadic). | 114,585 |

What is (are) xeroderma pigmentosum ? | Xeroderma pigmentosum, which is commonly known as XP, is an inherited condition characterized by an extreme sensitivity to ultraviolet (UV) rays from sunlight. This condition mostly affects the eyes and areas of skin exposed to the sun. Some affected individuals also have problems involving the nervous system. The signs of xeroderma pigmentosum usually appear in infancy or early childhood. Many affected children develop a severe sunburn after spending just a few minutes in the sun. The sunburn causes redness and blistering that can last for weeks. Other affected children do not get sunburned with minimal sun exposure, but instead tan normally. By age 2, almost all children with xeroderma pigmentosum develop freckling of the skin in sun-exposed areas (such as the face, arms, and lips); this type of freckling rarely occurs in young children without the disorder. In affected individuals, exposure to sunlight often causes dry skin (xeroderma) and changes in skin coloring (pigmentation). This combination of features gives the condition its name, xeroderma pigmentosum. People with xeroderma pigmentosum have a greatly increased risk of developing skin cancer. Without sun protection, about half of children with this condition develop their first skin cancer by age 10. Most people with xeroderma pigmentosum develop multiple skin cancers during their lifetime. These cancers occur most often on the face, lips, and eyelids. Cancer can also develop on the scalp, in the eyes, and on the tip of the tongue. Studies suggest that people with xeroderma pigmentosum may also have an increased risk of other types of cancer, including brain tumors. Additionally, affected individuals who smoke cigarettes have a significantly increased risk of lung cancer. The eyes of people with xeroderma pigmentosum may be painfully sensitive to UV rays from the sun. If the eyes are not protected from the sun, they may become bloodshot and irritated, and the clear front covering of the eyes (the cornea) may become cloudy. In some people, the eyelashes fall out and the eyelids may be thin and turn abnormally inward or outward. In addition to an increased risk of eye cancer, xeroderma pigmentosum is associated with noncancerous growths on the eye. Many of these eye abnormalities can impair vision. About 30 percent of people with xeroderma pigmentosum develop progressive neurological abnormalities in addition to problems involving the skin and eyes. These abnormalities can include hearing loss, poor coordination, difficulty walking, movement problems, loss of intellectual function, difficulty swallowing and talking, and seizures. When these neurological problems occur, they tend to worsen with time. Researchers have identified at least eight inherited forms of xeroderma pigmentosum: complementation group A (XP-A) through complementation group G (XP-G) plus a variant type (XP-V). The types are distinguished by their genetic cause. All of the types increase skin cancer risk, although some are more likely than others to be associated with neurological abnormalities. | 94,297 |
What is (are) Myasthenia Gravis ? | Myasthenia gravis is disease that causes weakness in the muscles under your control. It happens because of a problem in communication between your nerves and muscles. Myasthenia gravis is an autoimmune disease. Your body's own immune system makes antibodies that block or change some of the nerve signals to your muscles. This makes your muscles weaker. Common symptoms are trouble with eye and eyelid movement, facial expression and swallowing. But it can also affect other muscles. The weakness gets worse with activity, and better with rest. There are medicines to help improve nerve-to-muscle messages and make muscles stronger. With treatment, the muscle weakness often gets much better. Other drugs keep your body from making so many abnormal antibodies. There are also treatments which filter abnormal antibodies from the blood or add healthy antibodies from donated blood. Sometimes surgery to take out the thymus gland helps. For some people, myasthenia gravis can go into remission and they do not need medicines. The remission can be temporary or permanent. If you have myasthenia gravis, it is important to follow your treatment plan. If you do, you can expect your life to be normal or close to it.

How to diagnose Prader-Willi syndrome ? | How is Prader-Willi syndrome diagnosed? There are clinical diagnostic criteria for Prader-Willi syndrome (PWS) that were developed in the past that continue to be useful. These criteria can be viewed on the National Institute of Health's NICHD Web site. However, the current mainstay of a diagnosis when PWS is suspected is a form of genetic testing called DNA methylation testing. This testing can detect abnormal, parent-specific imprinting on the region of chromosome 15 that is responsible for PWS. It determines whether the region is maternally inherited only (i.e., the paternally contributed region is absent) and confirms a diagnosis in more than 99% of affected people. DNA methylation testing is especially important in people who have non-classic features, or are too young to show enough features to make the diagnosis based on signs and symptoms alone. | 100,386 |
What is (are) Pheochromocytoma ? | Pheochromocytoma is a rare tumor that usually starts in the cells of one of your adrenal glands. Although they are usually benign, pheochromocytomas often cause the adrenal gland to make too many hormones. This can lead to high blood pressure and cause symptoms such as - Headaches - Sweating - Pounding of the heart - Being shaky - Being extremely pale Sometimes pheochromocytoma is part of another condition called multiple endocrine neoplasia syndrome (MEN). People with MEN often have other cancers and other problems involving hormones. Doctors use lab tests and imaging tests to diagnose it. Surgery is the most common treatment. Other options include radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells. NIH: National Cancer Institute | 92,658 |
What is (are) Fanconi anemia ? | Fanconi anemia is a condition that affects many parts of the body. People with this condition may have bone marrow failure, physical abnormalities, organ defects, and an increased risk of certain cancers. The major function of bone marrow is to produce new blood cells. These include red blood cells, which carry oxygen to the body's tissues; white blood cells, which fight infections; and platelets, which are necessary for normal blood clotting. Approximately 90 percent of people with Fanconi anemia have impaired bone marrow function that leads to a decrease in the production of all blood cells (aplastic anemia). Affected individuals experience extreme tiredness (fatigue) due to low numbers of red blood cells (anemia), frequent infections due to low numbers of white blood cells (neutropenia), and clotting problems due to low numbers of platelets (thrombocytopenia). People with Fanconi anemia may also develop myelodysplastic syndrome, a condition in which immature blood cells fail to develop normally. More than half of people with Fanconi anemia have physical abnormalities. These abnormalities can involve irregular skin coloring such as unusually light-colored skin (hypopigmentation) or caf-au-lait spots, which are flat patches on the skin that are darker than the surrounding area. Other possible symptoms of Fanconi anemia include malformed thumbs or forearms and other skeletal problems including short stature; malformed or absent kidneys and other defects of the urinary tract; gastrointestinal abnormalities; heart defects; eye abnormalities such as small or abnormally shaped eyes; and malformed ears and hearing loss. People with this condition may have abnormal genitalia or malformations of the reproductive system. As a result, most affected males and about half of affected females cannot have biological children (are infertile). Additional signs and symptoms can include abnormalities of the brain and spinal cord (central nervous system), including increased fluid in the center of the brain (hydrocephalus) or an unusually small head size (microcephaly). Individuals with Fanconi anemia have an increased risk of developing a cancer of blood-forming cells in the bone marrow called acute myeloid leukemia (AML) or tumors of the head, neck, skin, gastrointestinal system, or genital tract. The likelihood of developing one of these cancers in people with Fanconi anemia is between 10 and 30 percent. | 97,532 |

What are the treatments for Primary Hyperparathyroidism ? | Surgery
Surgery to remove the overactive parathyroid gland or glands is the only definitive treatment for the disorder, particularly if the patient has a very high blood calcium level or has had a fracture or a kidney stone. In patients without any symptoms, guidelines are used to identify who might benefit from parathyroid surgery.3
When performed by experienced endocrine surgeons, surgery cures primary hyperparathyroidism in more than 95 percent of operations.2
Surgeons often use imaging tests before surgery to locate the overactive gland to be removed. The most commonly used tests are sestamibi and ultrasound scans. In a sestamibi scan, the patient receives an injection of a small amount of radioactive dye that is absorbed by overactive parathyroid glands. The overactive glands can then be viewed using a special camera.
Surgeons use two main strategies to remove the overactive gland or glands:
- Minimally invasive parathyroidectomy. This type of surgery, which can be done on an outpatient basis, may be used when only one of the parathyroid glands is likely to be overactive. Guided by a tumor-imaging test, the surgeon makes a small incision in the neck to remove the gland. The small incision means that patients typically have less pain and a quicker recovery than with more invasive surgery. Local or general anesthesia may be used for this type of surgery. - Standard neck exploration. This type of surgery involves a larger incision that allows the surgeon to access and examine all four parathyroid glands and remove the overactive ones. This type of surgery is more extensive and typically requires a hospital stay of 1 to 2 days. Surgeons use this approach if they plan to inspect more than one gland. General anesthesia is used for this type of surgery.
Almost all people with primary hyperparathyroidism who have symptoms can benefit from surgery. Experts believe that those without symptoms but who meet guidelines for surgery will also benefit from surgery. Surgery can lead to improved bone density and fewer fractures and can reduce the chance of forming kidney stones. Other potential benefits are being studied by researchers.
Surgery for primary hyperparathyroidism has a complication rate of 13 percent when performed by experienced endocrine surgeons.4 Rarely, patients undergoing surgery experience damage to the nerves controlling the vocal cords, which can affect speech. A small number of patients lose all their healthy parathyroid tissue and thus develop chronic low calcium levels, requiring lifelong treatment with calcium and some form of vitamin D. This complication is called hypoparathyroidism. The complication rate is slightly higher for operations on multiple tumors than for a single adenoma because more extensive surgery is needed.
People with primary hyperparathyroidism due to familial hypocalciuric hypercalcemia should not have surgery.
Monitoring
Some people who have mild primary hyperparathyroidism may not need immediate or even any surgery and can be safely monitored. People may wish to talk with their health care provider about long-term monitoring if they
- are symptom-free - have only slightly elevated blood calcium levels - have normal kidneys and bone density
Long-term monitoring should include periodic clinical evaluations, annual serum calcium measurements, annual serum creatinine measurements to check kidney function, and bone density measurements every 1 to 2 years.
Vitamin D deficiency should be corrected if present. Patients who are monitored need not restrict calcium in their diets.
If the patient and health care provider choose long-term monitoring, the patient should
- drink plenty of water - exercise regularly - avoid certain diuretics, such as thiazides
Either immobilizationthe inability to move due to illness or injuryor gastrointestinal illness with vomiting or diarrhea that leads to dehydration can cause blood calcium levels to rise further in someone with primary hyperparathyroidism. People with primary hyperparathyroidism should seek medical attention if they find themselves immobilized or dehydrated due to vomiting or diarrhea.
Medications
Calcimimetics are a new class of medications that decrease parathyroid gland secretion of PTH. The calcimimetic, cinacalcet (Sensipar), has been approved by the U.S. Food and Drug Administration for the treatment of secondary hyperparathyroidism caused by dialysisa blood-filtering treatment for kidney failureand primary hyperparathyroidism caused by parathyroid cancer. Cinacalcet has also been approved for the management of hypercalcemia associated with primary hyperparathyroidism.
A number of other medications are being studied to learn whether they may be helpful in treating primary hyperparathyroidism. These medications include bisphosphonates and selective estrogen receptor modulators. | 89,643 |

People with Myhre syndrome usually have delayed development of language and motor skills such as crawling and walking. Most have intellectual disability that ranges from mild to moderate. Some have behavioral issues such as features of autism or related developmental disorders affecting communication and social interaction. People with Myhre syndrome often have hearing loss, which can be caused by changes in the inner ear (sensorineural deafness), changes in the middle ear (conductive hearing loss), or both (mixed hearing loss). Growth is reduced in people with this disorder, beginning before birth and continuing through adolescence. Affected individuals have a low birth weight and are generally shorter than about 97 percent of their peers throughout life. People with Myhre syndrome typically have stiffness of the skin and are usually described as having a muscular appearance. Skeletal abnormalities associated with this disorder include thickening of the skull bones, flattened bones of the spine (platyspondyly), broad ribs, underdevelopment of the winglike structures of the pelvis (hypoplastic iliac wings), and unusually short fingers and toes (brachydactyly). Affected individuals often have joint problems (arthropathy), including stiffness and limited mobility. Typical facial features in people with Myhre syndrome include narrow openings of the eyelids (short palpebral fissures), a shortened distance between the nose and upper lip (a short philtrum), a sunken appearance of the middle of the face (midface hypoplasia), a small mouth with a thin upper lip, and a protruding jaw (prognathism). Some affected individuals also have an opening in the roof of the mouth (a cleft palate), a split in the lip (a cleft lip), or both. Other features that occur in some people with this disorder include constriction of the throat (laryngotracheal stenosis), high blood pressure (hypertension), heart or eye abnormalities, and in males, undescended testes (cryptorchidism). A disorder sometimes called laryngotracheal stenosis, arthropathy, prognathism, and short stature (LAPS) syndrome is now generally considered to be the same condition as Myhre syndrome because it has similar symptoms and the same genetic cause. | 106,306 |
What causes Chiari malformation type 1 ? | What causes Chiari malformation type 1? Primary or congenital Chiari malformations are caused by structural defects in the brain and spinal cord that occur during fetal development. The underlying cause of the structural defects are not completely understood, but may involve genetic mutations or lack of proper vitamins or nutrients in the maternal diet. Less frequently, Chiari malformation type 1 is acquired after birth. Causes of acquired Chiari malformation type 1 involve the excessive draining of spinal fluid from the lumbar or thoracic areas of the spine as a result of injury, exposure to harmful substances, or infection.

Is Aicardi syndrome inherited ? | Nearly all known cases of Aicardi syndrome are sporadic, which means that they are not passed down through generations and occur in people with no history of the disorder in their family. The disorder is believed to result from new gene mutations. Aicardi syndrome is classified as an X-linked dominant condition. While the gene associated with this disorder is not known, it is believed to be located on the X chromosome. In females (who have two X chromosomes), a mutation in one of the two copies of the gene in each cell is sufficient to cause the disorder. In males (who have only one X chromosome), a mutation in the only copy of the gene in each cell is nearly always lethal very early in development, so almost all babies with Aicardi syndrome are female. However, a few affected males with an extra copy of the X chromosome in each cell (47,XXY) have been identified. Males with a 47,XXY chromosome pattern also have a condition called Klinefelter syndrome. | 93,610 |
What is (are) Pustular psoriasis ? | Pustular psoriasis is a rare form of psoriasis that is characterized by widespread pustules and reddish skin. This condition can occur alone or with plaque-type psoriasis. Most cases of pustular psoriasis are thought to be "multifactorial" or associated with the effects of multiple genes in combination with lifestyle and environmental factors. There are several triggers for this conditions including withdrawal from corticosteroids, exposure to various medications and/or infections. Some cases of the generalized form are caused by changes (mutations) in the IL36RN gene and are inherited in an autosomal recessive pattern. In severe cases, hospitalization may be required. Treatment aims to alleviate the associated symptoms and may include certain medications and/or phototherapy. | 101,042 |

What are the symptoms of Congenital Heart Defects ? | Many congenital heart defects cause few or no signs and symptoms. A doctor may not even detect signs of a heart defect during a physical exam.
Some heart defects do cause signs and symptoms. They depend on the number, type, and severity of the defects. Severe defects can cause signs and symptoms, usually in newborns. These signs and symptoms may include:
Rapid breathing
Cyanosis (a bluish tint to the skin, lips, and fingernails)
Fatigue (tiredness)
Poor blood circulation
Congenital heart defects don't cause chest pain or other painful symptoms.
Heart defects can cause heart murmurs (extra or unusual sounds heard during a heartbeat). Doctors can hear heart murmurs using a stethoscope. However, not all murmurs are signs of congenital heart defects. Many healthy children have heart murmurs.
Normal growth and development depend on a normal workload for the heart and normal flow of oxygen-rich blood to all parts of the body. Babies who have congenital heart defects may have cyanosis and tire easily while feeding. As a result, they may not gain weight or grow as they should.
Older children who have congenital heart defects may get tired easily or short of breath during physical activity.
Many types of congenital heart defects cause the heart to work harder than it should. With severe defects, this can lead to heart failure. Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. Symptoms of heart failure include:
Shortness of breath or trouble breathing
Fatigue with physical activity
A buildup of blood and fluid in the lungs
Swelling in the ankles, feet, legs, abdomen, and veins in the neck | 91,680 |

What is (are) Osteoarthritis ? | Affects Many Older People Osteoarthritis is the most common form of arthritis among older people, and it is one of the most frequent causes of physical disability among older adults. The disease affects both men and women. Before age 45, osteoarthritis is more common in men than in women. After age 45, osteoarthritis is more common in women. It is estimated that 33.6% (12.4 million) of individuals age 65 and older are affected by the disease. Osteoarthritis occurs when cartilage, the tissue that cushions the ends of the bones within the joints, breaks down and wears away. In some cases, all of the cartilage may wear away, leaving bones that rub up against each other. Joint Stiffness and Pain Symptoms range from stiffness and mild pain that comes and goes to severe joint pain. Osteoarthritis affects hands, low back, neck, and weight-bearing joints such as knees, hips, and feet. osteoarthritis affects just joints, not internal organs. Hands Osteoarthritis of the hands seems to run in families. If your mother or grandmother has or had osteoarthritis in their hands, youre at greater-than-average risk of having it too. Women are more likely than men to have osteoarthritis in the hands. For most women, it develops after menopause. When osteoarthritis involves the hands, small, bony knobs may appear on the end joints (those closest to the nails) of the fingers. They are called Heberdens (HEBerr-denz) nodes. Similar knobs, called Bouchards (boo-SHARDZ) nodes, can appear on the middle joints of the fingers. Fingers can become enlarged and gnarled, and they may ache or be stiff and numb. The base of the thumb joint also is commonly affected by osteoarthritis. Knees The knees are among the joints most commonly affected by osteoarthritis. Symptoms of knee osteoarthritis include stiffness, swelling, and pain, which make it hard to walk, climb, and get in and out of chairs and bathtubs. Osteoarthritis in the knees can lead to disability. Hips The hips are also common sites of osteoarthritis. As with knee osteoarthritis, symptoms of hip osteoarthritis include pain and stiffness of the joint itself. But sometimes pain is felt in the groin, inner thigh, buttocks, or even the knees. Osteoarthritis of the hip may limit moving and bending, making daily activities such as dressing and putting on shoes a challenge. Spine Osteoarthritis of the spine may show up as stiffness and pain in the neck or lower back. In some cases, arthritis-related changes in the spine can cause pressure on the nerves where they exit the spinal column, resulting in weakness, tingling, or numbness of the arms and legs. In severe cases, this can even affect bladder and bowel function. | 91,007 |

What are the genetic changes related to Tietz syndrome ? | Tietz syndrome is caused by mutations in the MITF gene. This gene provides instructions for making a protein that plays a role in the development, survival, and function of certain types of cells. Molecules of the MITF protein attach (bind) to each other or with other proteins that have a similar structure, creating a two-protein unit (dimer). The dimer attaches to specific areas of DNA and helps control the activity of particular genes. On the basis of this action, the MITF protein is called a transcription factor. The MITF protein helps control the development and function of pigment-producing cells called melanocytes. Within these cells, this protein controls production of the pigment melanin, which contributes to hair, eye, and skin color. Melanocytes are also found in the inner ear and play an important role in hearing. Additionally, the MITF protein regulates the development of the retinal pigment epithelium. MITF gene mutations that cause Tietz syndrome either delete or change a single protein building block (amino acid) in an area of the MITF protein known as the basic motif region. Dimers incorporating the abnormal MITF protein cannot be transported into the cell nucleus to bind with DNA. As a result, most of the dimers are unavailable to bind to DNA, which affects the development of melanocytes and the production of melanin. The resulting reduction or absence of melanocytes in the inner ear leads to hearing loss. Decreased melanin production (hypopigmentation) accounts for the light skin and hair color and the retinal pigment epithelium changes that are characteristic of Tietz syndrome. Researchers suggest that Tietz syndrome may represent a severe form of a disorder called Waardenburg syndrome, which can also be caused by MITF gene mutations. | 94,704 |

What is (are) Malaria ? | Malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito which feeds on humans. Infection with malaria parasites may result in a wide variety of symptoms, ranging from absent or very mild symptoms to severe disease and even death. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness. In general, malaria is a curable disease if diagnosed and treated promptly and correctly. Treatment depends on many factors including disease severity, the species of malaria parasite causing the infection and the part of the world in which the infection was acquired. | 100,793 |
What is (are) Notalgia paresthetica ? | Notalgia paresthetica is a common chronic, localized itch, that usually affects patches of skin on the upper back. Occasionally be more widespread and involve other parts of the back, the shoulders and upper chest. People feel both the sensation of an itch and paresthesia (a sensation of tingling, pricking, or numbness of the skin). There are no signs on the skin except for signs of chronic scratching and rubbing. Amyloid deposits (a collection of a specific type of protein) may be found in skin biopsies, but this is thought to be a secondary event. The cause of the itch in notalgia paresthetica may be due to the compression of spinal nerves by bones or muscles as the nerves emerge through the vertebrae to the back muscles. Sometimes degenerative changes in the area of the vertebrae that innervate the affected back muscles can be seen, but not always. Symptoms of notalgia paresthetica may respond to topical capsaicin treatment. | 110,226 |
