Question: How to diagnose Waardenburg syndrome ?

Answer: How is Waardenburg syndrome diagnosed? A diagnosis of Waardenburg syndrome (WS) is made based on signs and symptoms present. In 1992, the Waardenburg Consortium proposed diagnostic criteria, which includes both major and minor criteria. A clinical diagnosis of WS type 1 (the most common type) needs 2 major, or 1 major and 2 minor criteria. Major criteria: Congenital sensorineural hearing loss Iris pigmentary (coloration) abnormality, such as heterochromia iridis (complete, partial, or segmental); pale blue eyes (isohypochromia iridis); or pigmentary abnormalities of the fundus (part of the eye opposite the pupil) Abnormalities of hair pigmentation, such as white forelock (lock of hair above the forehead), or loss of hair color Dystopia canthorum  lateral displacement of inner angles (canthi) of the eyes (in WS types 1 and 3 only) Having a 1st degree relative with Waardenburg syndrome Minor criteria: Congenital leukoderma (hypopigmented patches of skin) Synophrys (connected eyebrows or "unibrow") or medial eyebrow flare Broad or high nasal bridge (uppermost part of the nose) Hypoplasia of the nostrils Premature gray hair (under age 30) WS type 2 has similar features to WS type 1, but the inner canthi are normal (no dystopia cantorum present). WS type 3 also has similar features to WS type 1, but is additionally characterized by musculoskeletal abnormalities such as muscle hypoplasia (underdevelopment); flexion contractures (inability to straighten joints); or syndactyly (webbed or fused fingers or toes). WS type 4 has similar features to WS type 2, but with Hirschsprung disease (a condition resulting from missing nerve cells in the muscles of part or all of the large intestine).
Question: What are the genetic changes related to fragile X-associated tremor/ataxia syndrome ?

Answer: Mutations in the FMR1 gene increase the risk of developing FXTAS. The FMR1 gene provides instructions for making a protein called FMRP, which helps regulate the production of other proteins. FMRP plays a role in the development of synapses, which are specialized connections between nerve cells. Synapses are critical for relaying nerve impulses.  Individuals with FXTAS have a mutation in which a DNA segment, known as a CGG triplet repeat, is expanded within the FMR1 gene. Normally, this DNA segment is repeated from 5 to about 40 times. In people with FXTAS, however, the CGG segment is repeated 55 to 200 times. This mutation is known as an FMR1 gene premutation. An expansion of more than 200 repeats, a full mutation, causes a more serious condition called fragile X syndrome, which is characterized by intellectual disability, learning problems, and certain physical features.  For unknown reasons, the premutation leads to the overproduction of abnormal FMR1 mRNA that contains the expanded repeat region. The FMR1mRNA is the genetic blueprint for the production of FMRP. Researchers believe that the high levels of mRNA cause the signs and symptoms of FXTAS. The mRNA has been found in clumps of proteins and mRNA (intranuclear inclusions) in brain and nerve cells in people with FXTAS. It is thought that attaching to FMR1 mRNA and forming clumps keeps the other proteins from performing their functions, although the effect of the intranuclear inclusions is unclear. In addition, the repeat expansion makes producing FMRP from the mRNA blueprint more difficult, and as a result, people with the FMR1 gene premutation can have less FMRP than normal. A reduction in the protein is not thought to be involved in FXTAS. However, it may cause mild versions of the features seen in fragile X syndrome, such as prominent ears, anxiety, and mood swings.
Question: What is (are) vitiligo ?

Answer: Vitiligo is a condition that causes patchy loss of skin coloring (pigmentation). The average age of onset of vitiligo is in the mid-twenties, but it can appear at any age. It tends to progress over time, with larger areas of the skin losing pigment. Some people with vitiligo also have patches of pigment loss affecting the hair on their scalp or body.  Researchers have identified several forms of vitiligo. Generalized vitiligo (also called nonsegmental vitiligo), which is the most common form, involves loss of pigment (depigmentation) in patches of skin all over the body. Depigmentation typically occurs on the face, neck, and scalp, and around body openings such as the mouth and genitals. Sometimes pigment is lost in mucous membranes, such as the lips. Loss of pigmentation is also frequently seen in areas that tend to experience rubbing, impact, or other trauma, such as the hands, arms, and places where bones are close to the skin surface (bony prominences). Another form called segmental vitiligo is associated with smaller patches of depigmented skin that appear on one side of the body in a limited area; this occurs in about 10 percent of affected individuals.  Vitiligo is generally considered to be an autoimmune disorder. Autoimmune disorders occur when the immune system attacks the body's own tissues and organs. In people with vitiligo the immune system appears to attack the pigment cells (melanocytes) in the skin. About 15 to 25 percent of people with vitiligo are also affected by at least one other autoimmune disorder, particularly autoimmune thyroid disease, rheumatoid arthritis, type 1 diabetes, psoriasis, pernicious anemia, Addison disease, or systemic lupus erythematosus.  In the absence of other autoimmune conditions, vitiligo does not affect general health or physical functioning. However, concerns about appearance and ethnic identity are significant issues for many affected individuals.
Question: What are the symptoms of Neonatal hemochromatosis ?

Answer: What are the signs and symptoms of Neonatal hemochromatosis? The Human Phenotype Ontology provides the following list of signs and symptoms for Neonatal hemochromatosis. 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) Abnormal localization of kidney 90% Anteverted nares 90% Aplasia/Hypoplasia of the nipples 90% Blepharophimosis 90% Congenital hepatic fibrosis 90% Hypoglycemia 90% Abnormal bleeding - Autosomal recessive inheritance - Cholestasis - Cirrhosis - Congenital onset - Hepatic failure - Hepatic fibrosis - Hepatocellular necrosis - Increased serum ferritin - Increased serum iron - Intrauterine growth retardation - Nonimmune hydrops fetalis - Oligohydramnios - Prolonged neonatal jaundice - Rapidly progressive - 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 is (are) Blau syndrome ?

Answer: Blau syndrome is an inflammatory disorder that primarily affects the skin, joints, and eyes. Signs and symptoms begin in childhood, usually before age 4.  A form of skin inflammation called granulomatous dermatitis is typically the earliest sign of Blau syndrome. This skin condition causes a persistent rash that can be scaly or involve hard lumps (nodules) that can be felt under the skin. The rash is usually found on the torso, arms, and legs.  Arthritis is another common feature of Blau syndrome. In affected individuals, arthritis is characterized by inflammation of the lining of joints (the synovium). This inflammation, known as synovitis, is associated with swelling and joint pain. Synovitis usually begins in the joints of the hands, feet, wrists, and ankles. As the condition worsens, it can restrict movement by decreasing the range of motion in many joints.  Most people with Blau syndrome also develop uveitis, which is swelling and inflammation of the middle layer of the eye (the uvea). The uvea includes the colored portion of the eye (the iris) and related tissues that underlie the white part of the eye (the sclera). Uveitis can cause eye irritation and pain, increased sensitivity to bright light (photophobia), and blurred vision. Other structures in the eye can also become inflamed, including the outermost protective layer of the eye (the conjunctiva), the tear glands, the specialized light-sensitive tissue that lines the back of the eye (the retina), and the nerve that carries information from the eye to the brain (the optic nerve). Inflammation of any of these structures can lead to severe vision impairment or blindness.  Less commonly, Blau syndrome can affect other parts of the body, including the liver, kidneys, brain, blood vessels, lungs, and heart. Inflammation involving these organs and tissues can cause life-threatening complications.
Question: What is (are) Nutrition for Advanced Chronic Kidney Disease in Adults ?

Answer: Damaged kidneys allow phosphorus, a mineral found in many foods, to build up in the blood. Too much phosphorus in the blood pulls calcium from the bones, making the bones weak and likely to break. Too much phosphorus may also make skin itch. Foods such as milk and cheese, dried beans, peas, colas, canned iced teas and lemonade, nuts, and peanut butter are high in phosphorus. A renal dietitian can help people with advanced CKD learn how to limit phosphorus in their diet.
                
As CKD progresses, a person may need to take a phosphate binder such as sevelamer hydrochloride (Renagel), lanthanum carbonate (Fosrenol), calcium acetate (PhosLo), or calcium carbonate (Tums) to control the phosphorus in the blood. These medications act like sponges to soak up, or bind, phosphorus while it is in the stomach. Because it is bound, the phosphorus does not get into the blood. Instead, it is removed from the body in the stool.
                
The table below lists some high-phosphorus foods and suggestions for low-phosphorus alternatives that are healthier for people with advanced CKD.

Question: What is (are) Hydrocephalus ?

Answer: Hydrocephalus is a condition in which the primary characteristic is excessive accumulation of cerebrospinal fluid (CSF) -- the clear fluid that surrounds the brain and spinal cord. This excessive accumulation results in an abnormal dilation of the spaces in the brain called ventricles. This dilation causes potentially harmful pressure on the tissues of the brain. Hydrocephalus may be congenital or acquired. Congenital hydrocephalus is present at birth and may be caused by genetic abnormalities or developmental disorders such as spina bifida and encephalocele. Acquired hydrocephalus develops at the time of birth or at some point afterward and can affect individuals of all ages. For example, hydrocephalus ex-vacuo occurs when there is damage to the brain caused by stroke or traumatic injury. Normal pressure hydrocephalus occurs most often among the elderly. It may result from a subarachnoid hemorrhage, head trauma, infection, tumor, or complications of surgery, although many people develop normal pressure hydrocephalus without an obvious cause. Symptoms of hydrocephalus vary with age, disease progression, and individual differences in tolerance to CSF. In infancy, the most obvious indication of hydrocephalus is often the rapid increase in head circumference or an unusually large head size. In older children and adults, symptoms may include headache followed by vomiting, nausea, papilledema (swelling of the optic disk, which is part of the optic nerve), downward deviation of the eyes (called "sunsetting"), problems with balance, poor coordination, gait disturbance, urinary incontinence, slowing or loss of development (in children), lethargy, drowsiness, irritability, or other changes in personality or cognition, including memory loss. Hydrocephalus is diagnosed through clinical neurological evaluation and by using cranial imaging techniques such as ultrasonography, computer tomography (CT), magnetic resonance imaging (MRI), or pressure-monitoring techniques.
