How might Camurati-Engelmann disease (CED) be treated? Several medical therapies including corticosteroids, biphosphonates, and non-steroidal anti-inflammatory drugs (NSAIDs) have been used to manage the symptoms of Camurati-Engelmann disease (CED). NSAIDs and bisphosphonates have not been proven to be effective for most people with CED. Corticosteroids may relieve some of the symptoms such as pain and weakness and can also improve gait and exercise tolerance, however corticosteroids have serious side effects with long term use. More recently, losartan, an angiotensin II type 1 receptor antagonist, has been reported to reduce limb pain and increase muscle strength in multiple case reports. However, the effectiveness of losartan needs more study to determine if it is effective for those with CED and without major side effects. Exercise programs when they are tolerated have also been found to be beneficial. Please note, case reports report the clinical findings associated with individual cases. It is important to keep in mind that the clinical findings documented in these case reports are based on specific individuals and may differ from one affected person to another.

A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Hemorrhagic stroke is the less common type. It happens when a blood vessel breaks and bleeds into the brain. Within minutes, brain cells begin to die. Causes include a bleeding aneurysm, an arteriovenous malformation (AVM), or an artery wall that breaks open. Symptoms of stroke are - Sudden numbness or weakness of the face, arm or leg (especially on one side of the body) - Sudden confusion, trouble speaking or understanding speech - Sudden trouble seeing in one or both eyes - Sudden trouble walking, dizziness, loss of balance or coordination - Sudden severe headache with no known cause It is important to treat strokes as quickly as possible. With a hemorrhagic stroke, the first steps are to find the cause of bleeding in the brain and then control it. Surgery may be needed. Post-stroke rehabilitation can help people overcome disabilities caused by stroke damage. National Institute of Neurological Disorders and Stroke

How is juvenile primary lateral sclerosis inherited? Juvenile primary lateral sclerosis 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.
Bacteria called Tropheryma whipplei (T. whipplei) cause Whipple disease. T. whipplei infection can cause internal sores, also called lesions, and thickening of tissues in the small intestine. The villi take on an abnormal, clublike appearance and the damaged intestinal lining does not properly absorb nutrients, causing diarrhea and malnutrition. Diarrhea is frequent, loose, and watery bowel movements. Malnutrition is a condition that develops when the body does not get the right amount of vitamins, minerals, and other nutrients it needs to maintain healthy tissues and organ function. Over time, the infection spreads to other parts of the persons body and will damage other organs.
Most insect bites are harmless, though they sometimes cause discomfort. Bee, wasp, and hornet stings and fire ant bites usually hurt. Mosquito and flea bites usually itch. Insects can also spread diseases. In the United States, some mosquitoes spread West Nile virus. Travelers outside the United States may be at risk for malaria and other infections. To prevent insect bites and their complications - Don't bother insects - Use insect repellant - Wear protective clothing - Be careful when you eat outside because food attracts insects - If you know you have severe allergic reactions to insect bites and stings (such as anaphylaxis), carry an emergency epinephrine kit
Congenital hypothyroidism is a condition that affects infants from birth and results from a partial or complete loss of thyroid function (hypothyroidism). The thyroid gland makes hormones that play an important role in regulating growth, brain development, and metabolism in the body. Congenital hypothyroidism occurs when the thyroid gland fails to develop or function properly. In the United States and many other countries, all newborns are tested for congenital hypothyroidism as part of newborn screening. If untreated, congenital hypothyroidism can lead to intellectual disability and abnormal growth. If treatment begins in the first month after birth, infants usually develop normally. Treatment involves medication to replace the missing thyroid hormones, such as levothyroxine. Most cases of congenital hypothyroidism occur in people with no history of the disorder in their family. About 15-20% of cases are due to an underlying gene mutation. Rarely, congenital hypothyroidism can be a symptom included in a larger genetic disorder called a syndrome.
A skin biopsy is the first step in diagnosing DH. Direct immunofluorescence of clinically normal skin adjacent to a lesion shows granular IgA deposits in the upper dermis. Histology of lesional skin may show microabscesses containing neutrophils and eosinophils. However, histology may reveal only excoriation due to the intense itching that patients experience. Blood tests for antiendomysial or anti-tissue transglutaminase antibodies may also suggest celiac disease. Blood tests for epidermal transglutaminase antibodies are positive in more than 90 percent of cases.5 All of these tests will become negative with prolonged adherence to a gluten-free diet. A positive biopsy and serology confirm DH and should be taken as indirect evidence of small bowel damage. A biopsy of the small bowel is usually not needed for DH diagnosis. However, if clinical signs of gastrointestinal disease are evident on examination, further workup may be required.2 Whether or not intestinal damage is evident, a gluten-free diet should be implemented because the rash of DH is gluten sensitive.4
Blau syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most affected individuals have one parent with the condition. In some cases, people with the characteristic features of Blau syndrome do not have a family history of the condition. Some researchers believe that these individuals have a non-inherited version of the disorder called early-onset sarcoidosis.
Atrial fibrillation (AF) describes the rapid, irregular beating of the left atrium (upper chamber) of the heart. These rapid contractions of the heart are weaker than normal contractions, resulting in slow flow of blood in the atrium. The blood pools and becomes sluggish and can result in the formation of blood clots. If a clot leaves the heart and travels to the brain, it can cause a stroke by blocking the flow of blood through cerebral arteries. Some people with AF have no symptoms, but others may experience a fluttering feeling in the area of the chest above the heart, chest pain, lightheadness or fainting, shortness of breath, and fatigue. AF is diagnosed by an electrocardiogram (ECG), a device that records the hearts electrical activity. Other tests are often performed to rule out contributing causes, such as high blood pressure, an overactive thyroid gland, heart failure, faulty heart valves, lung disease, and stimulant or alcohol abuse. Some people will have no identifiable cause for their AF.
Mutations in the EDA, EDAR, and EDARADD genes cause hypohidrotic ectodermal dysplasia. The EDA, EDAR, and EDARADD genes provide instructions for making proteins that work together during embryonic development. These proteins form part of a signaling pathway that is critical for the interaction between two cell layers, the ectoderm and the mesoderm. In the early embryo, these cell layers form the basis for many of the body's organs and tissues. Ectoderm-mesoderm interactions are essential for the formation of several structures that arise from the ectoderm, including the skin, hair, nails, teeth, and sweat glands. Mutations in the EDA, EDAR, or EDARADD gene prevent normal interactions between the ectoderm and the mesoderm and impair the normal development of hair, sweat glands, and teeth. The improper formation of these ectodermal structures leads to the characteristic features of hypohidrotic ectodermal dysplasia.
Type 1 hemochromatosis is one of the most common genetic disorders in the United States, affecting about 1 million people. It most often affects people of Northern European descent. The other types of hemochromatosis are considered rare and have been studied in only a small number of families worldwide.
Different forms of psoriasis have different symptoms. In many cases your doctor can diagnose psoriasis based on the signs seen in the physical exam as well as the symptoms you describe. Symptoms The most common symptoms of psoriasis are - patches of thick, red skin - skin inflammation - silvery scales - itching - pain. patches of thick, red skin skin inflammation silvery scales itching pain. Psoriasis most commonly affects the elbows, knees, scalp, lower back, face, palms, soles of the feet, nails, and soft tissues. Making a Diagnosis In most cases, your primary care provider can diagnose psoriasis simply by examining your skin. Because the symptoms of psoriasis may be similar to those of other skin diseases, however, sometimes the diagnosis is more difficult. You may need to see a dermatologist, a doctor who specializes in diagnosing and treating skin diseases. If your doctor isn't sure if you have psoriasis, he or she may order a biopsy. This involves removing a small sample of skin and looking at it under a microscope.
How might Floating-Harbor syndrome be treated? Treatment for Floating-Harbor syndrome is symptomatic and supportive. For example, dental problems and cataracts may be surgically corrected and sign language and/or speech therapy may help with delays in expressive language. Additional management strategies may be obtained from the Floating Harbor Syndrome Support Group at: http://www.floatingharborsyndromesupport.com/ or 336-492-2641.
What causes Dermatofibrosarcoma protuberans? The cause of DFSP is unknown but an injury to the affected skin may be a predisposing factor. Trauma at the affected site has been reported in approximately 10-20% of patients. Recent advances have shown that in approximately 90% of cases, dermatofibrosarcoma protuberans is associated with a rearrangement (translocation) of genetic material between chromosomes 17 and 22 which results in the fusion of two genes. The fused gene produces a protein which some believe may stimulate cells to multiply, leading to the tumor formation seen in dermatofibrosarcoma protuberans. This type of gene change is generally found only in tumor cells and is not inherited.
Lichen sclerosus is a chronic skin disorder that is more common in women, most often affecting the external part of the vagina (vulva) or the area around the anus. In men, it typically affects the tip of the penis. It can occur at any age but is usually seen in women over age 50. Some people have no symptoms, while others may experience itchiness (sometimes severe), discomfort, or blistering. It often lasts for years and can cause permanent scarring. The underlying cause of lichen sclerosus is not fully understood but it is thought to relate to an autoimmune process. Treatment may include topical steroids or other types of topical creams and/or surgery.
Urinary incontinence means a person leaks urine by accident. Urinary incontinence is a common bladder problem as people age. Women are more likely than men to leak urine. If this problem is happening to you, there is help. Urinary incontinence can often be controlled. Talk to your health care provider about what you can do. Learn about urinary incontinence in women. Learn about urinary incontinence in men.
What causes Juvenile Huntington disease (HD)? Mutations in the HTT gene cause Huntington disease. The HTT gene provides instructions for making a protein called huntingtin. Although the function of this protein is unknown, it appears to play an important role in nerve cells (neurons) in the brain. When the huntingtin protein is abnormally made, it is thought to lead to the death of neurons in certain areas of the brain, which causes the signs and symptoms of Juvenile HD. The HTT mutation that causes Huntington disease involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with juvenile HD, the CAG segment is repeated more than 60 times.
This condition is not inherited; it usually occurs as a random event during the formation of reproductive cells (eggs and sperm). An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes. In 48,XXYY syndrome, the extra sex chromosomes almost always come from a sperm cell. Nondisjunction may cause a sperm cell to gain two extra sex chromosomes, resulting in a sperm cell with three sex chromosomes (one X and two Y chromosomes). If that sperm cell fertilizes a normal egg cell with one X chromosome, the resulting child will have two X chromosomes and two Y chromosomes in each of the body's cells. In a small percentage of cases, 48,XXYY syndrome results from nondisjunction of the sex chromosomes in a 46,XY embryo very soon after fertilization has occurred. This means that an normal sperm cell with one Y chromosome fertilized a normal egg cell with one X chromosome, but right after fertilization nondisjunction of the sex chromosomes caused the embryo to gain two extra sex chromosomes, resulting in a 48,XXYY embryo.
Many disorders can affect our ability to speak and communicate. They range from saying sounds incorrectly to being completely unable to speak or understand speech. Causes include - Hearing disorders and deafness - Voice problems, such as dysphonia or those caused by cleft lip or palate - Speech problems like stuttering - Developmental disabilities - Learning disorders - Autism spectrum disorder - Brain injury - Stroke Some speech and communication problems may be genetic. Often, no one knows the causes. By first grade, about 5 percent of children have noticeable speech disorders. Speech and language therapy can help.

No single treatment is effective for all patients. Treatment should be individualized, and often combined, depending on patient characteristics such as age and tumor size. If the tumor has not yet invaded surrounding nonpituitary tissues, removal of the pituitary adenoma by an experienced neurosurgeon is usually the first choice. Even if a cure is not possible, surgery may be performed if the patient has symptoms of neurological problems such as loss of peripheral vision or cranial nerve problems. After surgery, hormone levels are measured to determine whether a cure has been achieved. This determination can take up to 8 weeks because IGF-I lasts a long time in the body's circulation. If cured, a patient must be monitored for a long time for increasing GH levels. If surgery does not normalize hormone levels or a relapse occurs, an endocrinologist should recommend additional drug therapy. With each medication, long-term therapy is necessary because their withdrawal can lead to rising GH levels and tumor re-expansion. Radiation therapy is generally reserved for patients whose tumors are not completely removed by surgery, who are not good candidates for surgery because of other health problems, or who do not respond adequately to surgery and medication.
Mantle cell lymphoma (MCL) belongs to a group of diseases known as non-Hodgkins lymphomas (NHL), which are cancers that affect the the lymphatic system (part of the immune system). MCL accounts for 6% of all non-Hodgkin lymphomas and is mostly found in males during their early 60s. Lymphocytes, which are white blood cells that make up the lymphatic system. There are two main types: B-lymphocytes (B-cells) and T-lymphocytes (T-cells). Mantel cell lymphoma is a B-cell lymphoma that develops from cancerous B-cells within a region of the lymph node known as the mantle zone. Although mantle cell lymphomas are slow-growing cancers, at the time of diagnosis, they are usually widespread in the lymph nodes and require intensive treatment because they can become lethal within a short period of time.
When EDA-ID is caused by mutations in the IKBKG gene, it is inherited in an X-linked recessive pattern. The IKBKG gene is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of the IKBKG gene, males are affected by X-linked recessive disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. When EDA-ID is caused by mutations in the NFKBIA gene, the condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
Short QT syndrome appears to be rare. At least 70 cases have been identified worldwide since the condition was discovered in 2000. However, the condition may be underdiagnosed because some affected individuals never experience symptoms.

West syndrome is characterized by a specific type of seizure (infantile spasms) seen in infancy and childhood. This syndrome leads to developmental regression and causes a specific pattern, known as hypsarrhythmia (chaotic brain waves), on electroencephalography (EEG) testing. The infantile spasms usually begin in the first year of life, typically between 4-8 months. The seizures primarily consist of a sudden bending forward of the body with stiffening of the arms and legs; some children arch their backs as they extend their arms and legs. Spasms tend to occur upon awakening or after feeding, and often occur in clusters of up to 100 spasms at a time. Infants may have dozens of clusters and several hundred spasms per day. Infantile spasms usually stop by age five, but may be replaced by other types of seizures. Many underlying disorders, such as birth injury, metabolic disorders, and genetic disorders can lead to these spasms, making it important to identify the underlying cause. In some children, no cause can be found.
Guillain-Barre syndrome is a rare disorder that causes your immune system to attack your peripheral nervous system (PNS). The PNS nerves connect your brain and spinal cord with the rest of your body. Damage to these nerves makes it hard for them to transmit signals. As a result, your muscles have trouble responding to your brain. No one knows what causes the syndrome. Sometimes it is triggered by an infection, surgery, or a vaccination. The first symptom is usually weakness or a tingling feeling in your legs. The feeling can spread to your upper body. In severe cases, you become almost paralyzed. This is life-threatening. You might need a respirator to breathe. Symptoms usually worsen over a period of weeks and then stabilize. Guillain-Barre can be hard to diagnose. Possible tests include nerve tests and a spinal tap. Most people recover. Recovery can take a few weeks to a few years. Treatment can help symptoms, and may include medicines or a procedure called plasma exchange. NIH: National Institute of Neurological Disorders and Stroke
Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. It causes a cough that often brings up mucus. It can also cause shortness of breath, wheezing, a low fever, and chest tightness. There are two main types of bronchitis: acute and chronic. Chronic bronchitis is one type of COPD (chronic obstructive pulmonary disease). The inflamed bronchial tubes produce a lot of mucus. This leads to coughing and difficulty breathing. Cigarette smoking is the most common cause. Breathing in air pollution, fumes, or dust over a long period of time may also cause it. To diagnose chronic bronchitis, your doctor will look at your signs and symptoms and listen to your breathing. You may also have other tests. Chronic bronchitis is a long-term condition that keeps coming back or never goes away completely. If you smoke, it is important to quit. Treatment can help with your symptoms. It often includes medicines to open your airways and help clear away mucus. You may also need oxygen therapy. Pulmonary rehabilitation may help you manage better in daily life. NIH: National Heart, Lung, and Blood Institute
If tests show that you have cancer, you should talk with your doctor in order to make treatment decisions. Working With a Team of Specialists A team of specialists often treats people with cancer. The team will keep the primary doctor informed about the patient's progress. The team may include a medical oncologist who is a specialist in cancer treatment, a surgeon, a radiation oncologist who is a specialist in radiation therapy, and others. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you request it. Clinical Trials for Prostate Cancer Some prostate cancer patients take part in studies of new treatments. These studies -- called clinical trials -- are designed to find out whether a new treatment is safe and effective. Often, clinical trials compare a new treatment with a standard one so that doctors can learn which is more effective. Men with prostate cancer who are interested in taking part in a clinical trial should talk with their doctor. The U.S. National Institutes of Health, through its National Library of Medicine and other Institutes, maintains a database of clinical trials at ClinicalTrials.gov. Click here to see a list of the current clinical trials on prostate cancer. A separate window will open. Click the "x" in the upper right hand corner of the "Clinical Trials" window to return here.
Oral or injected medications for psoriasis include methotrexate, cycloclosporine, oral retinoids, and biologics. These therapies, prescribed by your doctor, work in different ways to help control the underlying disease process.
What causes platelet storage pool deficiency? Platelet storage pool deficiency refers to a group of conditions that are caused by problems with the platelet granules. Platelet granules are tiny storage sacs found within the platelets which release various substances to help stop bleeding. Some platelet storage pool deficiencies are due to reduced or absent granules or granule contents. Others occur if the platelets are unable to empty the contents of the platelet granules into the bloodstream. Platelet storage pool deficiencies can be genetic or acquired (non-genetic). The four major genetic forms include dense body deficiency, gray platelet syndrome, Factor V Quebec, and mixed alpha-granule/dense body deficiency. Platelet storage pool deficiency is also a feature of several inherited conditions such as Hermansky-Pudlak syndrome, Chediak-Higashi syndrome, thrombocytopenia-absent radius (TAR) syndrome, and Wiskott-Aldrich syndrome. Causes of acquired platelet storage pool deficiencies include: Systemic lupus erythematosus Cardiovascular bypass Hairy-cell leukemia
MONA is rare; its prevalence is unknown. This condition has been reported in multiple populations worldwide.
Megalocytic interstitial nephritis is a rare chronic kidney disease that is characterized by inflammation of the kidney. It is similar to malakoplakia of the kidney. In this condition the inflammation is caused by various infiltrate, particularly histiocytes. A histiocyte is a type of immune cell that eats foreign substances in an effort to protect the body from infection.
Osteopetrosis can have several different patterns of inheritance. Most commonly, the disorder has an autosomal dominant inheritance pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. Most people with autosomal dominant osteopetrosis inherit the condition from an affected parent. Osteopetrosis can also be 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. OL-EDA-ID is inherited in an X-linked recessive pattern. The IKBKG gene is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.
Transverse myelitis is a neurological disorder caused by inflammation across both sides of one level, or segment, of the spinal cord. The segment of the spinal cord at which the damage occurs determines which parts of the body are affected. Damage at one segment will affect function at that segment and segments below it. In people with transverse myelitis, inflammation usually occurs at the thoracic (upper back) level, causing problems with leg movement and bowel and bladder control, which require signals from the lower segments of the spinal cord. What usually begins as a sudden onset of lower back pain, muscle weakness, or abnormal sensations in the toes and feet can rapidly progress to more severe symptoms, including paralysis, urinary retention, and loss of bowel control.
Portal hypertension is abnormally high blood pressure in branches of the portal vein, the large vein that brings blood from the intestine to the liver. Portal hypertension itself does not cause symptoms, but complications from the condition can lead to an enlarged abdomen, abdominal discomfort, confusion, drowsiness and internal bleeding. It may be caused by a variety of conditions, but cirrhosis is the most common cause in Western countries. Treatment is generally directed toward the cause of the condition, although emergency treatment is sometimes needed for serious complications.
Piriformis syndrome is a rare neuromuscular disorder that occurs when the piriformis muscle compresses or irritates the sciatic nerve-the largest nerve in the body. The piriformis muscle is a narrow muscle located in the buttocks. Compression of the sciatic nerve causes pain-frequently described as tingling or numbness-in the buttocks and along the nerve, often down to the leg. The pain may worsen as a result of sitting for a long period of time, climbing stairs, walking, or running.
Most foods that contain carbohydrates can cause gas. Foods that cause gas for one person may not cause gas for someone else. Some foods that contain carbohydrates and may cause gas are - beans - vegetables such as broccoli, cauliflower, cabbage, brussels sprouts, onions, mushrooms, artichokes, and asparagus - fruits such as pears, apples, and peaches - whole grains such as whole wheat and bran - sodas; fruit drinks, especially apple juice and pear juice; and other drinks that contain high fructose corn syrup, a sweetener made from corn - milk and milk products such as cheese, ice cream, and yogurt - packaged foodssuch as bread, cereal, and salad dressingthat contain small amounts of lactose, the sugar found in milk and foods made with milk - sugar-free candies and gums that contain sugar alcohols such as sorbitol, mannitol, and xylitol
Pseudoachondroplasia is an inherited disorder of bone growth. It was once thought to be related to another disorder of bone growth called achondroplasia, but without that disorder's characteristic facial features. More research has demonstrated that pseudoachondroplasia is a separate disorder. All people with pseudoachondroplasia have short stature. The average height of adult males with this condition is 120 centimeters (3 feet, 11 inches), and the average height of adult females is 116 centimeters (3 feet, 9 inches). Individuals with pseudoachondroplasia are not unusually short at birth; by the age of two, their growth rate falls below the standard growth curve. Other characteristic features of pseudoachondroplasia include short arms and legs; a waddling walk; joint pain in childhood that progresses to a joint disease known as osteoarthritis; an unusually large range of joint movement (hyperextensibility) in the hands, knees, and ankles; and a limited range of motion at the elbows and hips. Some people with pseudoachondroplasia have legs that turn outward or inward (valgus or varus deformity). Sometimes, one leg turns outward and the other inward, which is called windswept deformity. Some affected individuals have a spine that curves to the side (scoliosis) or an abnormally curved lower back (lordosis). People with pseudoachondroplasia have normal facial features, head size, and intelligence.
Spinocerebellar ataxia type 11 (SCA11) is characterized by progressive cerebellar ataxia (difficulty walking and balance) and abnormal eye signs (jerky pursuit, horizontal and vertical movements (nystagmus), pyramidal features (increased muscular tonus, increased reflexes and an abnormal reflex known as Babinski sign and inability to make to perform fine movements), peripheral neuropathy with numbness, weakness or pain in the feet or hands or other places of the body and dystonia. It is a very rare disease and very few patients have been reported to date. In them, age of onset ranged from the early teens to the second decade of life and life span was normal. Diagnosis is based on signs and symptoms and with a genetic exam showing an alteration (mutation) in the TTBK2 gene. It is inherited in an autosomal dominant manner. Treatment may include speech and language therapy for talking and swallowing problems, occupational therapy, including home adaptations, physiotherapy and use of assistive walking devices and ankle-foot orthotics (AFOs) for those with neuropathy.
There is no standard treatment for iniencephaly since most infants rarely live longer than a few hours. Medicine is based more on prevention using supplementation with folic acid. Numerous studies have demonstrated that mothers can reduce the risk of neural tube birth defects such as iniencephaly by up to 70 percent with daily supplements of at least 4 mg of folic acid. Pregnant women should avoid taking antiepileptic drugs, diuretics, antihistamines, and sulfa drugs, which have been shown to be associated with an increased risk of neural tube defects. Maternal obesity and diabetes are also known to increase the risk for these disorders.
This condition 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.

Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases characterized by progressive weakness and degeneration of the skeletal muscles that control movement. Some forms of MD are seen in infancy or childhood, while others may not appear until middle age or later. The disorders differ in terms of the distribution and extent of muscle weakness (some forms of MD also affect cardiac muscle), age of onset, rate of progression, and pattern of inheritance. The prognosis for people with MD varies according to the type and progression of the disorder. There is no specific treatment to stop or reverse any form of MD. Treatment is supportive and may include physical therapy, respiratory therapy, speech therapy, orthopedic appliances used for support, corrective orthopedic surgery, and medications including corticosteroids, anticonvulsants (seizure medications), immunosuppressants, and antibiotics. Some individuals may need assisted ventilation to treat respiratory muscle weakness or a pacemaker for cardiac (heart) abnormalities.
Generally there are three treatment stages for stroke: prevention, therapy immediately after the stroke, and post-stroke rehabilitation. Therapies to prevent a first or recurrent stroke are based on treating an individual's underlying risk factors for stroke, such as hypertension, atrial fibrillation, and diabetes. Acute stroke therapies try to stop a stroke while it is happening by quickly dissolving the blood clot causing an ischemic stroke or by stopping the bleeding of a hemorrhagic stroke. Post-stroke rehabilitation helps individuals overcome disabilities that result from stroke damage. Medication or drug therapy is the most common treatment for stroke. The most popular classes of drugs used to prevent or treat stroke are antithrombotics (antiplatelet agents and anticoagulants) and thrombolytics.
Peripheral neuropathy, also called distal symmetric neuropathy or sensorimotor neuropathy, is nerve damage in the arms and legs. Feet and legs are likely to be affected before hands and arms. Many people with diabetes have signs of neuropathy that a doctor could note but feel no symptoms themselves. Symptoms of peripheral neuropathy may include - numbness or insensitivity to pain or temperature - a tingling, burning, or prickling sensation - sharp pains or cramps - extreme sensitivity to touch, even light touch - loss of balance and coordination These symptoms are often worse at night. Peripheral neuropathy may also cause muscle weakness and loss of reflexes, especially at the ankle, leading to changes in the way a person walks. Foot deformities, such as hammertoes and the collapse of the midfoot, may occur. Blisters and sores may appear on numb areas of the foot because pressure or injury goes unnoticed. If an infection occurs and is not treated promptly, the infection may spread to the bone, and the foot may then have to be amputated. Many amputations are preventable if minor problems are caught and treated in time.
What causes benign rolandic epilepsy? Benign rolandic epilepsy is a genetic syndrome with an autosomal dominant mode of inheritance. Although the gene associated with the condition has not been identified, Neubauer et al. (1998) found evidence of linkage to chromosome 15q. Juvenile myoclonic epilepsy has been mapped to the same region.
What are the signs and symptoms of Thyroid cancer, follicular? The Human Phenotype Ontology provides the following list of signs and symptoms for Thyroid cancer, follicular. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of metabolism/homeostasis - Autosomal dominant inheritance - Follicular thyroid carcinoma - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. 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.
What are the signs and symptoms of spondylothoracic dysostosis? Signs and symptoms of spondylothoracic dysostosis, include spine and vertebral abnormalities which result in a shortened spine, neck, and trunk, as well as rib anomalies including fused ribs which in combination with the spine anomalies result in a "crab-like" appearance to the rib cage. The shortened spine and rib cage anomalies can cause serious breathing problems and recurring lung infections. These complications result in a 32% death rate in early childhood. Other complications of spondylothoracic dysostosis, include shortened stature (due to the spine and vertebral defects) and limited neck motion. Symptom and symptom severity may vary from patient to patient, however symptoms tend to be the worse for children who carry two "E230X" mutations in the MESP2 gene. Most patients with spondylothoracic dysostosis have normal intelligence and neurological problems are infrequent.

Psoriasis is a chronic skin disease. Chronic means that it lasts a long time, often a lifetime. Psoriasis affects more than 5 million adults in the United States. It appears about equally in males and females. Psoriasis occurs when the skin cells grow too quickly. The body does not shed these excess cells and they build up on the surface of the skin, forming thick, scaly patches.
Leukocyte adhesion deficiency type 1 is estimated to occur in 1 per million people worldwide. At least 300 cases of this condition have been reported in the scientific literature.
CM-AVM is thought to occur in at least 1 in 100,000 people of northern European origin. The prevalence of the condition in other populations is unknown.
How might glucose transporter type 1 deficiency syndrome be treated? There is currently no cure for glucose transporter type 1 deficiency syndrome (GLUT1 deficiency syndrome); however, a special diet (called a ketogenic diet) may help control symptoms in some affected people. The GLUT1 Deficiency Foundation offers an information page with detailed information regarding the ketogenic diet. Please click on the link to access this resource.
Restless legs syndrome (RLS) affects about 515 percent of Americans. Many people who have RLS have family members with the disorder. RLS can affect people of any racial or ethnic group, but the disorder is more common in people of Northern European descent. RLS affects both genders, but women are more likely to have it than men. The number of cases of RLS rises with age. Many people who have RLS are diagnosed in middle age. People who develop RLS early in life tend to have a family history of the disorder. People who have certain diseases or conditions or who take certain medicines are more likely to develop RLS. (For more information, go to "What Causes Restless Legs Syndrome?") For example, pregnancy is a risk factor for RLS. It usually occurs during the last 3 months of pregnancy. The disorder usually improves or goes away after giving birth. Some women may continue to have symptoms after giving birth. Other women may develop RLS again later in life.
The NINDS supports a broad program of research on disorders of the nervous system, including BEB. Much of this research is aimed at increasing understanding of these disorders and finding ways to prevent, treat, and cure them.
Multifocal motor neuropathy is a progressive muscle disorder characterized by muscle weakness in the hands, with differences from one side of the body to the other in the specific muscles involved. It affects men much more than women. Symptoms also include muscle wasting, cramping, and involuntary contractions or twitching of the leg muscles. The disorder is sometimes mistaken for amyotrophic laterial sclerosis (ALS, or Lou Gehrig's disease) but unlike ALS, it is treatable. An early and accurate diagnosis allows patients to recover quickly.
What are the signs and symptoms of Keratosis, seborrheic? The Human Phenotype Ontology provides the following list of signs and symptoms for Keratosis, seborrheic. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Verrucae - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. 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.
Within the NINDS research programs, trigeminal neuralgia is addressed primarily through studies associated with pain research. NINDS vigorously pursues a research program seeking new treatments for pain and nerve damage with the ultimate goal of reversing debilitating conditions such as trigeminal neuralgia. NINDS has notified research investigators that it is seeking grant applications both in basic and clinical pain research.
Signs of childhood ALL include fever and bruising. These and other signs and symptoms may be caused by childhood ALL or by other conditions. Check with your child's doctor if your child has any of the following: - Fever. - Easy bruising or bleeding. - Petechiae (flat, pinpoint, dark-red spots under the skin caused by bleeding). - Bone or joint pain. - Painless lumps in the neck, underarm, stomach, or groin. - Pain or feeling of fullness below the ribs. - Weakness, feeling tired, or looking pale. - Loss of appetite.
About 5.7 million people in the United States have heart failure. The number of people who have this condition is growing. Heart failure is more common in: People who are age 65 or older. Aging can weaken the heart muscle. Older people also may have had diseases for many years that led to heart failure. Heart failure is a leading cause of hospital stays among people on Medicare. Blacks are more likely to have heart failure than people of other races. Theyre also more likely to have symptoms at a younger age, have more hospital visits due to heart failure, and die from heart failure. People who areoverweight. Excess weight puts strain on the heart. Being overweight also increases your risk of heart disease and type 2diabetes. These diseases can lead to heart failure. People who have had a heart attack. Damage to the heart muscle from a heart attack and can weaken the heart muscle. Children who havecongenital heart defectsalso can develop heart failure. These defects occur if the heart, heart valves, or blood vessels near the heart dont form correctly while a baby is in the womb. Congenital heart defects can make the heart work harder. This weakens the heart muscle, which can lead to heart failure. Children dont have the same symptoms of heart failure or get the same treatments as adults. This Health Topic focuses on heart failure in adults.
The NINDS supports research on paralytic disorders such as alternating hemiplegia, with the goals of learning more about these disorders and finding ways to prevent, treat and, ultimately cure them.
Mntrier disease is a condition characterized by inflammation and ulcers of the mucosa (inner lining) of the stomach and by overgrowth of the cells that make up the mucosa. The condition is associated with the following signs: protein loss from the stomach, excessive mucus production, and hypochlorhydria (low levels of stomach acid) or achlorhydia (absent levels of stomach acid). Symptoms usually include vomiting, diarrhea, and weight loss. The disease may increase an individual's risk of developing stomach cancer.
What causes orofaciodigital syndrome type 2? Orofaciodigital syndrome type 2 is caused by mutations (changes) of an as yet unidentified gene.
What causes Cowden syndrome? Most cases of Cowden syndrome are caused by changes (mutations) in the PTEN gene. PTEN is a tumor suppressor gene which means that it encodes a protein that helps keep cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in PTEN result in a defective protein that is unable to carry out its normal role. This leads to the development of the various tumors and cancers associated with Cowden syndrome. Rarely, Cowden syndrome is caused by mutations in KLLN, SDHB, SDHC, SDHD, PIK3CA or AKT1. Some affected families have no identifiable mutation in any of the genes associated with Cowden syndrome; in these families, the exact underlying cause is unknown.
Isobutyryl-CoA dehydrogenase (IBD) deficiency is a condition that disrupts the breakdown of certain proteins. Normally, proteins from food are broken down into parts called amino acids. Amino acids can be further processed to provide energy for growth and development. People with IBD deficiency have inadequate levels of an enzyme that helps break down a particular amino acid called valine. Most people with IBD deficiency are asymptomatic, which means they do not have any signs or symptoms of the condition. A few children with IBD deficiency have developed features such as a weakened and enlarged heart (dilated cardiomyopathy), weak muscle tone (hypotonia), and developmental delay. This condition may also cause low numbers of red blood cells (anemia) and very low blood levels of carnitine, which is a natural substance that helps convert certain foods into energy. The range of signs and symptoms associated with IBD deficiency remains unclear because very few affected individuals have been reported.
People with diabetes should work with their health care team to prevent or manage CKD through the following steps: - measure A1C levelsa blood test that provides information about a persons average blood glucose levels for the previous 3 months at least twice a year and keep A1C levels below 7 percent - learn about insulin injections, diabetes medications, meal planning, physical activity, and blood glucose monitoring - find out whether protein, salt, or liquid should be limited in the diet - see a registered dietitian to help with meal planning - check blood pressure every visit with a health care provider or at least two to four times a year - learn about possible benefits from taking an ACE inhibitor or an ARB if a person has high blood pressure - measure eGFR at least once a year to check kidney function - get the amount of protein in the urine tested at least once a year to check for kidney damage
How might HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) be treated? There is no established treatment program for HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). Corticosteroids may relieve some symptoms, but arent likely to change the course of the disorder. Clinical studies suggest that interferon alpha provides benefits over short periods and some aspects of disease activity may be improved favorably using interferon beta. Stiff and spastic muscles may be treated with lioresal or tizanidine. Urinary dysfunction may be treated with oxybutynin.
Survival for men with breast cancer is similar to survival for women with breast cancer. Survival for men with breast cancer is similar to that for women with breast cancer when their stage at diagnosis is the same. Breast cancer in men, however, is often diagnosed at a later stage. Cancer found at a later stage may be less likely to be cured. Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following: - The stage of the cancer (whether it is in the breast only or has spread to other places in the body). - The type of breast cancer. - Estrogen-receptor and progesterone-receptor levels in the tumor tissue. - Whether the cancer is also found in the other breast. - The patients age and general health.
Peripheral artery disease (P.A.D.) affects millions of people in the United States. The disease is more common in blacks than any other racial or ethnic group.The major risk factors for P.A.D. are smoking, older age, and having certain diseases or conditions. Smoking Smoking is the main risk factor for P.A.D. and your risk increases if you smoke or have a history of smoking. Quitting smoking slows the progress of P.A.D. People who smoke and people who have diabetes are at highest risk for P.A.D. complications, such as gangrene (tissue death) in the leg from decreased blood flow. Older Age Older age also is a risk factor for P.A.D. Plaque builds up in your arteries as you age.Older age combined with other risk factors, such as smoking or diabetes, also puts you at higher risk for P.A.D. Diseases and Conditions Many diseases and conditions can raise your risk of P.A.D., including: Diabetes High blood pressure High blood cholesterol Coronary heart disease Stroke Metabolic syndrome

How might herpes zoster oticus be treated? Treatment for herpes zoster oticus typically includes anti-inflammatory drugs called steroids, which may reduce the inflammation of the nerves and help to ease the pain. Antiviral medications are usually prescribed, although whether antiviral medications are beneficial for treating this condition has not been confirmed. Strong pain medications may be prescribed if the pain continues. An eye patch may be recommended to prevent injury to the cornea (corneal abrasion) and damage to the eye if it does not close completely. Vertigo (feeling that the room is spinning) and dizziness may be treated with other medications.

What are the signs and symptoms of Warthin tumor? Warthin tumor is a benign (noncancerous) tumor of the salivary glands. They most commonly arise in the parotid glands, the largest salivary glands which are located in each cheek above the jaw in front of the ears. Approximately 5-14% of cases are bilateral and 12-20% of affected people experience multicentric (more than one tumor which formed separately from one another) disease. The first symptom is usually a firm, painless bump. Without treatment, the swelling may gradually increase overtime which can cause facial nerve palsy (difficulty moving one side of the face).
Mutations in the TBX5 gene cause Holt-Oram syndrome. This gene provides instructions for making a protein that plays a role in the development of the heart and upper limbs before birth. In particular, this gene appears to be important for the process that divides the developing heart into four chambers (cardiac septation). The TBX5 gene also appears to play a critical role in regulating the development of bones in the arm and hand. Mutations in this gene probably disrupt the development of the heart and upper limbs, leading to the characteristic features of Holt-Oram syndrome.
This condition 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.

Hepatoblastoma is a rare malignant (cancerous) tumor of the liver that usually occurs in the first 3 years of life. In early stages of the condition, there may be no concerning signs or symptoms. As the tumor gets larger, affected children may experience a painful, abdominal lump; swelling of the abdomen; unexplained weight loss; loss of appetite; and/or nausea and vomiting. The exact underlying cause of hepatoblastoma is poorly understood. Risk factors for the tumor include prematurity with a very low birth weight, early exposure to hepatitis B infection, biliary atresia, and several different genetic conditions (i.e. Beckwith-Wiedemann syndrome, familial adenomatous polyposis, Aicardi syndrome, Glycogen storage disease, and Simpson-Golabi-Behmel syndrome). Treatment varies based on the severity of the condition but may include a combination of surgery, watchful waiting, chemotherapy, and/or radiation therapy.
This condition 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.
Mutations in the ARG1 gene cause arginase deficiency. Arginase deficiency belongs to a class of genetic diseases called urea cycle disorders. The urea cycle is a sequence of reactions that occurs in liver cells. This cycle processes excess nitrogen, generated when protein is used by the body, to make a compound called urea that is excreted by the kidneys. The ARG1 gene provides instructions for making an enzyme called arginase. This enzyme controls the final step of the urea cycle, which produces urea by removing nitrogen from arginine. In people with arginase deficiency, arginase is damaged or missing, and arginine is not broken down properly. As a result, urea cannot be produced normally, and excess nitrogen accumulates in the blood in the form of ammonia. The accumulation of ammonia and arginine are believed to cause the neurological problems and other signs and symptoms of arginase deficiency.
The prevalence of beta-ureidopropionase deficiency is unknown. A small number of affected individuals from populations around the world have been described in the medical literature. In Japan, the prevalence of beta-ureidopropionase deficiency has been estimated as 1 in 6,000 people. Researchers suggest that in many affected individuals with absent or mild neurological problems, the condition may never be diagnosed.
Most cases of 18q deletion syndrome are not inherited. The deletion occurs most often as a random event during the formation of reproductive cells (eggs or sperm) or in early fetal development. Affected people typically have no history of the disorder in their family. In some cases, 18q deletion syndrome is inherited, usually from a mildly affected parent. The deletion can also be inherited from an unaffected parent who carries a chromosomal rearrangement called a balanced translocation, in which no genetic material is gained or lost. Individuals with a balanced translocation do not usually have any related health problems; however, the translocation can become unbalanced as it is passed to the next generation. Children who inherit an unbalanced translocation can have a chromosomal rearrangement with extra or missing genetic material. Individuals with 18q deletion syndrome who inherit an unbalanced translocation are missing genetic material from the long arm of chromosome 18, which results in the signs and symptoms of this disorder.
This condition affects about 1 per million people worldwide. It is much more common in certain areas of the province of Quebec, Canada.
For many people, natural treatments can help relieve the symptoms of psoriasis. There are many natural treatments you can try on your own, but you should never use them to replace the treatment your doctor prescribes. Some natural treatments you may want to try are - sunlight - aloe - fish oil - Dead Sea salts - cayenne. sunlight aloe fish oil Dead Sea salts cayenne.

How might hyper IgM syndrome be treated? The cornerstone of treatment for individuals with hyper IgM syndrome is regular injections of intravenous immunogloblulin (IVIG). This treatment not only supplies missing IgG antibodies, but also prompts a drop in IgM antibodies. Patients with neutropenia can take granulocyte colony-stimulating factor (G-CSF). Antibiotics may also be prescribed to prevent the respiratory infection, pneumocystis carinii pneumonia. Most children with hyper-IgM syndrome respond well to treatment, become symptom-free and resume normal growth.
This condition 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.
What causes complex regional pain syndrome? The underlying cause of complex regional pain syndrome (CRPS) is not well understood. In most cases it occurs after an illness or injury that did not directly damage the nerves in the affected area (Type I). In some cases, it occurs after a specific nerve injury (Type II). The exact trigger of CRPS after an injury is not known, but it may be due to abnormal interactions between the central and peripheral nervous systems, and/or inappropriate inflammatory responses.
What causes Rotor syndrome? Rotor syndrome is an inherited disorder caused by having mutations in both the SLCO1B1 and SLCO1B3 genes. These genes provide instructions for making proteins that are found in liver cells, where they transport bilirubin and other substances from the blood into the liver so that they can be cleared from the body. In the liver, bilirubin is dissolved in a digestive fluid called bile, and then excreted from the body. The mutations in the SLCO1B1 and SLCO1B3 genes that cause Rotor syndrome either prevent the production of the transporting proteins, or prevent them from functioning properly. When this occurs, bilirubin is not effectively removed from the body and builds up, leading to jaundice.
HDGC is inherited in an autosomal dominant pattern, which means one copy of the altered CDH1 gene in each cell is sufficient to increase the risk of developing cancer. In most cases, an affected person has one parent with the condition.
Hydromyelia refers to an abnormal widening of the central canal of the spinal cord that creates a cavity in which cerebrospinal fluid (commonly known as spinal fluid) can accumulate. As spinal fluid builds up, it may put abnormal pressure on the spinal cord and damage nerve cells and their connections. Hydromyelia is sometimes used interchangeably with syringomyelia, the name for a condition that also involves cavitation in the spinal cord. In hydromyelia, the cavity that forms is connected to the fourth ventricle in the brain, and is almost always associated in infants and children with hydrocephalus or birth defects such as Chiari Malformation II and Dandy-Walker syndrome. Syringomyelia, however, features a closed cavity and occurs primarily in adults, the majority of whom have Chiari Malformation type 1 or have experienced spinal cord trauma. Symptoms, which may occur over time, include weakness of the hands and arms, stiffness in the legs; and sensory loss in the neck and arms. Some individuals have severe pain in the neck and arms. Diagnosis is made by magnetic resonance imaging (MRI), which reveals abnormalities in the anatomy of the spinal cord..
What are the signs and symptoms of Keratitis, hereditary? The Human Phenotype Ontology provides the following list of signs and symptoms for Keratitis, hereditary.

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.
Bell's palsy is a form of temporary facial paralysis which results from damage or trauma to one of the facial nerves. This disorder is characterized by the sudden onset of facial paralysis that often affects just one side and can cause significant facial distortion. Symptoms vary, but may include twitching, weakness, drooping eyelid or corner of the mouth, drooling, dry eye or mouth, impairment of taste, and excessive tearing in the eye. While the exact cause is unknown, many researchers believe that a virus may lead to swelling of the 7th cranial nerve. Steroids, such as prednisone, may reduce the inflammation and swelling. Other medications used to treat Bell's palsy include acyclovir (to fight viral infections) and aspirin, acetaminophen, or ibuprofen (to relieve pain). Physical therapy, facial massage and acupuncture have also been used.
Warning signs of osteoarthritis include - joint pain - swelling or tenderness in one or more joints - stiffness after getting out of bed or sitting for a long time - a crunching feeling or sound of bone rubbing on bone. joint pain swelling or tenderness in one or more joints stiffness after getting out of bed or sitting for a long time a crunching feeling or sound of bone rubbing on bone. Not everyone with osteoarthritis develops symptoms. In fact, only a third of people with x-ray evidence of osteoarthritis report pain or other symptoms.
Liposarcoma is a tumor that arises from fat tissue. This tumor often occurs in the thigh, behind the knee, or in the abdomen, but it can be found in other parts of the body. Because a liposarcoma may grow into surrounding tissues or organs, it is considered a malignant tumor.
Aicardi-Goutieres syndrome is an inherited condition that mainly affects the brain, immune system, and skin. It is characterized by early-onset severe brain dysfunction (encephalopathy) that usually results in severe intellectual and physical disability. Additional symptoms may include epilepsy, painful, itchy skin lesion (chilblains), vision problems, and joint stiffness. Symptoms usually progress over several months before the disease course stabilizes. There are six different types of Aicardi-Goutieres syndrome, which are distinguished by the gene that causes the condition: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, and ADAR genes. Most cases are inherited in an autosomal recessive pattern, although rare autosomal dominant cases have been reported. Treatment is symptomatic and supportive.
Panic disorder is a type of anxiety disorder. It causes panic attacks, which are sudden feelings of terror when there is no real danger. You may feel as if you are losing control. You may also have physical symptoms, such as - Fast heartbeat - Chest or stomach pain - Breathing difficulty - Weakness or dizziness - Sweating - Feeling hot or a cold chill - Tingly or numb hands Panic attacks can happen anytime, anywhere, and without warning. You may live in fear of another attack and may avoid places where you have had an attack. For some people, fear takes over their lives and they cannot leave their homes. Panic disorder is more common in women than men. It usually starts when people are young adults. Sometimes it starts when a person is under a lot of stress. Most people get better with treatment. Therapy can show you how to recognize and change your thinking patterns before they lead to panic. Medicines can also help. NIH: National Institute of Mental Health
