Question:  What is (are) Epithelial basement membrane corneal dystrophy ?
Answer: Epithelial basement membrane corneal dystrophy is a condition where the epithelium of the cornea (the outermost region of the cornea) loses its normal clarity due to a buildup of cloudy material. It gets its name from the unusual appearance of the cornea during an eye exam. This dystrophy occurs when the epithelium's basement membrane develops abnormally, causing the epithelial cells to not properly adhere to it. This leads to recurrent epithelial erosions, which can cause blurred vision and severe pain. This condition is usually not inherited. However, families with autosomal dominant inheritance and mutations in the TGFBI gene have been identified.
Question:  What are the symptoms of Epithelial basement membrane corneal dystrophy ?
Answer: What are the signs and symptoms of Epithelial basement membrane corneal dystrophy? A chronic problem seen in this condition is the epithelial erosions. They can alter the cornea's normal curvature, causing periodic blurred vision. These erosions may also expose the nerve endings that line the tissue, resulting in moderate to severe pain lasting as long as several days. Generally, the pain will be worse upon awakening in the morning. Other symptoms include sensitivity to light, excessive tearing, and foreign body sensation in the eye. This condition usually affects adults between the ages of 40 and 70, although it can develop earlier in life. It gets its name from the unusual appearance of the cornea during an eye exam. Most often, the affected epithelium will have a map-like appearance, i.e., large, slightly gray outlines that look like a continent on a map. There may also be clusters of opaque dots close to the map-like patches. Less frequently, the irregular basement membrane will form concentric lines in the central cornea that resemble small fingerprints. Epithelial basement membrane corneal dystrophy is not a progressive condition. Typically, it will flare up occasionally for a few years and then go away on its own, with no lasting loss of vision. Most people never know that they have this condition, since they do not have any pain or vision loss. The Human Phenotype Ontology provides the following list of signs and symptoms for Epithelial basement membrane corneal dystrophy. 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 - Corneal dystrophy - Map-dot-fingerprint corneal dystrophy - Recurrent corneal erosions - 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.
Question:  What are the treatments for Epithelial basement membrane corneal dystrophy ?
Answer: How might epithelial basement membrane corneal dystrophy be treated? Because most people do not develop noticeable signs or symptoms, treatment usually is not necessary. However, if treatment is needed, doctors will try to control the pain associated with the epithelial erosions. They may patch the eye to immobilize it, or prescribe lubricating eye drops and ointments. With treatment, these erosions usually heal within three days, although periodic flashes of pain may occur for several weeks thereafter. Other treatments include anterior corneal punctures to allow better adherence of cells; corneal scraping to remove eroded areas of the cornea and allow regeneration of healthy epithelial tissue; and use of the excimer laser to remove surface irregularities.

Question:  What is (are) Basilar migraine ?
Answer: Basilar migraine is a type of migraine headache with aura that is associated with bilateral (on both sides) pain at the back of the head. An aura is a group of symptoms that generally serve as a warning sign that a bad headache is coming and may include dizziness and vertigo, slurred speech, ataxia, tinnitus, visual changes, and loss of balance. Although basilar migraines can occur in men and women of all ages, they are most common in adolescent girls. The exact underlying cause is not well understood. However, migraines are likely complex disorders that are influenced by multiple genes in combination with lifestyle and environmental factors. In rare cases, the susceptibility to basilar migraines may be caused by a change (mutation) in the ATP1A2 gene or CACNA1A gene. During episodes, affected people are typically treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and antiemetic medications to help alleviate the symptoms.

Question:  What causes Basilar migraine ?
Answer: What causes a basilar migraine? The exact underlying cause of basilar migraines is not well understood. Basilar migraines, like all types of migraines, are likely complex disorders that are influenced by multiple genes in combination with lifestyle and environmental factors. Scientists also suspect that nerve abnormalities and/or altered blood flow to certain parts of the brain (brainstem and occipital lobes, specifically) may also play a role in the development of basilar migraines. The susceptibility to basilar migraines may rarely be caused by a change (mutation) in the ATP1A2 gene or CACNA1A gene. In these cases, episodes of basilar migraines may occur in more than one family member.
Question:  Is Basilar migraine inherited ?
Answer: Are basilar migraines inherited? In most cases, basilar migraines are not inherited. However, the susceptibility to basilar migraines may rarely be caused by a change (mutation) in the ATP1A2 gene or CACNA1A gene. In these cases, they are inherited in an autosomal dominant manner. This means that to be affected, a person only needs a mutation in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with one of these mutations has a 50% chance with each pregnancy of passing along the altered gene to his or her child.
Question:  How to diagnose Basilar migraine ?
Answer: How is a basilar migraine diagnosed? A diagnosis of basilar migraine is made based on the presence of characteristic signs and symptoms. Although there are no tests available to confirm the diagnosis, additional testing may be ordered to rule out other conditions that can cause similar features. These tests may include: Brain MRI MR angiogram (MRA) Electroencephalogram 24-hour heart monitor Specialized blood tests
Question:  What are the treatments for Basilar migraine ?
Answer: How are basilar migraines treated? During episodes of basilar migraines, people are generally treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and antiemetic medications to help alleviate the symptoms. In some cases, a nerve block can be used to treat pain if other therapies are ineffective. In people with episodes of basilar migraines that are frequent, prolonged, or particularly debilitating, certain medications such as verapamil or topiramate may be prescribed as a preventative therapy.
Question:  What is (are) Mitochondrial DNA-associated Leigh syndrome ?
Answer: Mitochondrial DNA-associated Leigh syndrome is a progressive brain disorder that usually appears in infancy or early childhood. Affected children may experience vomiting, seizures, delayed development, muscle weakness, and problems with movement. Heart disease, kidney problems, and difficulty breathing can also occur in people with this disorder. Mitochondrial DNA-associated Leigh syndrome is a subtype of Leigh syndrome and is caused by changes in mitochondrial DNA. Mutations in at least 11 mitochondrial genes have been found to cause mtDNA-associated Leigh syndrome. This condition has an inheritance pattern known as maternal or mitochondrial inheritance. Because mitochondria can be passed from one generation to the next only through egg cells (not through sperm cells), only females pass mitochondrial DNA-associated Leigh syndrome to their children.

Question:  What is (are) Central core disease ?
Answer: Central core disease (CCD) is an inherited condition that involves muscle weakness, skeletal abnormalities, and an increased chance of having a severe reaction to some anesthesia medications.  Muscle weakness ranges from mild to severe and typically affects muscles in the trunk and upper legs, though muscles in the neck and face can also be affected. Skeletal abnormalities may include curving of the spine (scoliosis), dislocation of the hip, or restricted motion in certain joints (contractures).  Some individuals with CCD have an increased chance of having a severe reaction to anesthesia, called malignant hyperthermia, which may cause muscle rigidity or break-down (rhabdomyolysis), a high fever, or a rapid heart beat.  RYR1 is the only gene associated with CCD and clinical testing is available to look for disease-causing alterations in this gene known as mutations.

Question:  How to diagnose Central core disease ?
Answer: How is central core disease diagnosed? Because the symptoms of central core disease can be quite variable, a physical examination alone is often not enough to establish a diagnosis.  A combination of the following examinations and testings can diagnosis this condition: a physical examination that confirms muscle weakness, a muscle biopsy that reveals a characteristic appearance of the muscle cells, and/or genetic testing that identifies a mutation in the RYR1.
Question:  What are the treatments for Central core disease ?
Answer: What treatments might be available for central core disease? Treatments for central core disease (CCD) depend on the symptoms experienced by each affected individual.  When someone is first diagnosed with this condition, a physical examination is done to assess the extent and severity of muscle weakness, and physical therapy and occupational therapy assessments to determine which therapies might be most beneficial.  Physical therapy, such as stretching or low-impact exercises, may help improve weakness.  Some skeletal abnormalities can be addressed with physical therapy, though others may require surgery.  As the muscle weakness and scoliosis associated with CCD can affect breathing, individuals diagnosed with this condition may benefit from pulmonary function tests.  If breathing is significantly affected, breathing exercises or other breathing support treatments may be recommended.  Another treatment option may be a medication called salbutamol, which was found to significantly increased muscle strength and stamina in six of eight children with CCD.
Question:  What is (are) Limb dystonia ?
Answer: Limb dystonia is characterized by excessive pulling of the muscles of a limb, such as the hand or foot. The arm or leg might also be involved. Specific symptoms depend on the combinations of muscles involved and how hard each one is pulling. Mild forms may be expressed as stiffness or soreness of a limb; more moderate forms are characterized by unwanted movements or postures; and in severe forms, abnormal postures may become fixed. Common examples of limb dystonia include writer's cramp and musician's dystonia. In most cases, the cause of limb dystonia remains unknown. Treatment is challenging. Botulinum toxin injection, oral medications, and physical therapy may help some patients.
Question:  What is (are) Currarino triad ?
Answer: Currarino triad or syndrome is an autosomal dominant hereditary condition which is characterized by the triad of sacral agenesis abnormalities (abnormally developed lower spine), anorectal malformation (most commonly in the form of anorectal stenosis) and presacral mass consisting of a teratoma, anterior sacral meningocele or both. However only 1 out of 5 cases of Currarino triad has all three abnormalities present. Currarino triad is considered a spectrum disorder with a wide variation in severity. Up to one-third of the patients are asymptomatic and may only be diagnosed during adulthood only on X-rays and ultrasound examinations that are performed for different reasons. Currarino triad is most often caused by mutations in the MNX1 gene. Treatment depends on the type and severity of abnormalities present, but may involve surgery.
