What is (are) Unna-Thost palmoplantar keratoderma ? | Unna-Thost palmoplantar keratoderma is a type of diffuse palmoplantar keratoderma that mostly affects the palms of the hands and soles of the feet. It usually begins in early childhood with redness of the palms and soles. The palms and soles gradually become thicker and develop a yellowish, waxy appearance. Increased sweating (hyperhidrosis) is quite common and there is a tendency to fungal and bacterial infections of the feet. This condition usually does not extend beyond the hands and feet. It may affect the knuckle pads and nails, but usually does not involve the thin skin on the top of the feet or hands. Unna-Thost palmoplantar keratoderma is inherited in an autosomal dominant fashion and caused by mutations in the KRT1 gene. | |
What are the symptoms of Unna-Thost palmoplantar keratoderma ? | What are the signs and symptoms of Unna-Thost palmoplantar keratoderma? The Human Phenotype Ontology provides the following list of signs and symptoms for Unna-Thost palmoplantar keratoderma. 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 - Nonepidermolytic palmoplantar keratoderma - 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 is (are) Left ventricular noncompaction ? | Left ventricular noncompaction (LVNC) is a rare heart condition. In LVNC the inside wall of the heart is spongy or grooved, instead of smooth. Signs and symptoms of LVNC vary, but may cause life-threatening abnormal heart rhythms and weakness of the heart muscle. Treatments, such as blood thinning medication and defibrillators, are available to control these heart symptoms. In rare cases, heart transplantation is needed. | |
What is (are) Tietz syndrome ? | Tietz syndrome is a rare condition that affects the development of melanocytes, the cells in our body that produce and contain melanin (the pigment that gives color to skin, hair, and eyes). Signs and symptoms of this condition are present from birth and usually include sensorineural hearing loss, fair skin, and light-colored hair. It is caused by changes (mutations) in the MITF gene and inherited in an autosomal dominant manner. The goal of treatment is to improve hearing; cochlear implantation may be considered. | |
What are the symptoms of Tietz syndrome ? | What are the signs and symptoms of Tietz syndrome? The signs and symptoms of Tietz syndrome are usually present at birth and may include: Severe, bilateral (both ears) sensorineural hearing loss Fair skin Light-colored hair Blue eyes The Human Phenotype Ontology provides the following list of signs and symptoms for Tietz syndrome.

How to diagnose Tietz syndrome ? | How is Tietz syndrome diagnosed? A diagnosis of Tietz syndrome is suspected in people with severe, bilateral (both ears) sensorineural hearing loss; fair skin; and light-colored hair. Identification of a change (mutation) in the MITF gene also supports this diagnosis. Diagnosing Tietz syndrome can be complicated since there are several different genetic conditions that can cause deafness and hypopigmentation, some of which are also caused by mutations in the MITF gene. It is, therefore, important for people with suspected Tietz syndrome to be evaluated by a healthcare provider who specializes in genetics. | |
What is (are) Spondylospinal thoracic dysostosis ? | Spondylospinal thoracic dysostosis is an extremely rare skeletal disorder characterized by a short, curved spine and fusion of the spinous processes, short thorax with 'crab-like' configuration of the ribs, underdevelopment of the lungs (pulmonary hypoplasia), severe arthrogryposis and multiple pterygia (webbing of the skin across joints), and underdevelopment of the bones of the mouth. This condition is believed to be inherited in an autosomal recessive manner. It does not appear to be compatible with life. | |

What is (are) Phaeohyphomycosis ? | Phaeohyphomycosis refers to fungal infections caused by dematiaceous (darkly, pigmented fungi). It can be associated with a variety of clinical syndromes including invasive sinusitis; nodules or abscesses beneath the skin; keratitis; lung masses; osteomyelitis; mycotic arthritis; endocarditis; brain abscess; and wide-spread infection. Although the condition can affect all people, it is most commonly diagnosed in immunocompetent and immunosuppressed people and can even be life-threatening in these populations. Treatment depends on the signs and symptoms present in each person but may include surgery and/or various medications. | |
What is (are) Mondini dysplasia ? | Mondini dysplasia is a type of inner ear malformation that is present at birth (congenital). Individuals with Mondini dysplasia have one and a half coils of the cochlea instead of the normal two coils. It may occur in one ear (unilateral) or both ears (bilateral) and can cause varying degrees of sensorineural hearing loss, although most individuals have profound hearing loss. The condition can also predispose affected individuals to recurrent meningitis. It is caused by disruption in the embryonic development of the inner ear during the seventh week of gestation. The condition may be isolated (occurring with no other conditions or malformations) or may occur with other ear malformations or a number of syndromes. Treatment options may include surgical repair of the defect to prevent recurrent meningitis; amplification aids for those with residual hearing; and cochlear implantation. | |
What are the symptoms of Mondini dysplasia ? | What are the signs and symptoms of Mondini dysplasia? Mondini dysplasia is a congenital malformation (present at birth). It may occur either unilaterally (in one ear) or bilaterally (in both ears). Most affected individuals have profound sensorineural hearing loss, but some individuals do have residual hearing. There have also been reports of affected individuals having normal hearing. Mondini dysplasia can also predispose to recurrent meningitis because the defect can act as a "port of entry" to the fluid that surrounds the brain and spinal cord (cerebrospinal fluid, or CSF). Sometimes, individuals are not diagnosed before several episodes of recurrent meningitis occur. The condition may occur with other abnormalities of the ear or other organs, or it may be isolated. The severity of the physical abnormality does not appear to correlate with the severity of the signs and symptoms in affected individuals. | |
What causes Mondini dysplasia ? | What causes Mondini dysplasia? The underlying cause of Mondini dysplasia (MD) in most individuals appears to remain unclear. Some have suggested that retinoids (vitamin A) or other factors a fetus may be exposed to early in pregnancy have contributed to some cases of isolated MD (occurring with no other abnormalities). The potential role of these factors has created increased difficulty in determining the real cause of isolated MD. Mutations in the SLC26A4 gene cause both Pendred syndrome and DFNB4 (non-syndromic hearing loss with inner ear abnormalities), which are both associated with MD. Though mutations in the SLC26A4 gene have also been found in individuals with enlarged vestibular aqueduct (EVA) with and without MD, studies have shown there does not appear to be a relationship between isolated MD and the SLC26A4 gene. Thus hearing impairment in individuals with isolated MD may be caused by factors other than mutations in the SLC26A4 gene. More recently, a type of mutation called a microdeletion (a tiny loss of genetic material on a chromosome that may span several genes) involving the POU3F4 gene on the X chromosome was detected in some individuals with familial MD. In cases where Mondini dysplasia is associated with a specific syndrome, the cause of the syndrome in the affected individual is assumed to be related to the occurrence of MD in those cases. Syndromes that have been associated with MD include Klippel Feil syndrome, Pendred syndrome, DiGeorge syndrome, and some chromosomal trisomies. | |
Is Mondini dysplasia inherited ? | Is Mondini dysplasia inherited? Mondini dysplasia usually occurs sporadically as an isolated abnormality (occurring in only one individual in a family with no other abnormalities) but it can be associated with a variety of syndromes including Klippel Feil syndrome, Pendred syndrome, DiGeorge syndrome, Wildervanck syndrome, Fountain syndrome, Johanson-Blizzard syndrome, and some chromosomal trisomies. These syndromes can be inherited in a variety of ways, but Mondini dysplasia may not occur in each affected individual. It has also has been reported in families with congenital sensorineural hearing loss, both with autosomal dominant and presumed autosomal recessive inheritance. One study described familial nonsyndromic Mondini dysplasia in a mother, son and daughter with presumed autosomal dominant inheritance; another study described familial nonsyndromic Mondini dysplasia in a family in which transmission was most consistent with autosomal recessive inheritance. It has also been suggested that Mondini dysplasia may be associated with substances that may harm a developing fetus when a pregnant woman is exposed (teratogens) such as thalidomide or rubella. Being that Mondini dysplasia has been associated with a variety of conditions, inheritance patterns, and both genetic and non-genetic causes, it appears to be inherited in some cases, with the inheritance pattern being dependent upon the underlying cause of the condition in each individual or family. | |
How to diagnose Mondini dysplasia ? | Is genetic testing available for Mondini dysplasia? Genetic testing may be available for Mondini dysplasia if it is associated with a specific syndrome for which genetic testing is available, or if a mutation has previously been identified in an affected individual in the family. Unfortunately, for many cases of isolated Mondini dysplasia, there is no clinical genetic testing available. GeneTests lists the names of laboratories that are performing genetic testing for many conditions that may be associated with Mondini dysplasia. Please note that most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, if you are interested in learning more, you will need to work with a health care provider or a genetics professional. | |
What are the treatments for Mondini dysplasia ? | How might Mondini dysplasia be treated? Surgery to repair the defect present with Mondini dysplasia is typically necessary to prevent recurrent meningitis. Prophylactic antimicrobial therapy (such as antibiotics) to prevent infection and conjugate pneumococcal vaccination are helpful in reducing the formation of bacteria in affected individuals. If an individual has residual hearing, hearing amplification aids may be useful. The use of cochlear implants to treat patients with inner ear malformations such as Mondini dysplasia has been increasingly successful. Various results of cochlear implantation in individuals with Mondini dysplasia have been reported in the literature. | |
What is (are) Gordon syndrome ? | Gordon Syndrome is a rare, inherited type of distal arthrogryposis typically characterized by a combination of camptodactyly (a permanent fixation of several fingers in a flexed position), clubfoot (abnormal bending inward of the foot), and less frequently, cleft palate. Intelligence is usually normal. In some cases, additional abnormalities such as scoliosis or undescended testicles in males may be present. The range and severity of symptoms may vary from case to case. Gordon syndrome is thought to be inherited in an autosomal dominant or X-linked dominant manner. The exact cause remains unknown. | |
What are the symptoms of Gordon syndrome ? | What are the signs and symptoms of Gordon syndrome? Gordon syndrome belongs to a group of conditions known as the distal arthrogryposes, which are characterized by stiffness and impaired mobility of certain joints of the lower arms and legs including the wrists, elbows, knees and/or ankles. The range and severity of features in affected individuals can vary. Most infants with Gordon syndrome have several fingers that are permanently fixed in a flexed position (camptodactyly), which may result in limited range of motion and compromised manual dexterity. Affected infants may also have clubfoot. Approximately 20-30% have cleft palate (incomplete closure of the roof of the mouth). Other signs and symptoms in some individuals may include a bifid uvula (abnormal splitting of the soft hanging tissue at the back of the throat); short stature; dislocation of the hip; abnormal backward curvature of the upper spine (lordosis); and/or kyphoscoliosis. In addition, some affected individuals may have drooping of the eyelids (ptosis); epicanthal folds; syndactyly (webbing of the fingers and/or toes); abnormal skin patterns on the hands and feet (dermatoglyphics); and/or a short, webbed neck (pterygium colli). Some affected males have undescended testes (cryptorchidism). Cognitive development is typically normal. The Human Phenotype Ontology provides the following list of signs and symptoms for Gordon syndrome. 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.

In these cases, the sign or symptom may be rare or common. | |
Is Gordon syndrome inherited ? | How is Gordon syndrome inherited? While some reports suggest Gordon syndrome may be inherited in an X-linked dominant manner, most agree that it is inherited in an autosomal dominant manner with reduced expressivity and incomplete penetrance in females. In autosomal dominant inheritance, having only one mutated copy of the disease-causing gene in each cell is sufficient to cause signs and symptoms of the condition. When an individual with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to inherit the mutated copy of the gene. If a condition shows variable or reduced expressivity, it means that there can be a range in the nature and severity of signs and symptoms among affected individuals. Incomplete penetrance means that a portion of the individuals who carry the mutated copy of the disease-causing gene will not have any features of the condition. | |

In these cases, the sign or symptom may be rare or common. | |
What is (are) Hypomyelination with atrophy of basal ganglia and cerebellum ? | Hypomyelination with atrophy of basal ganglia and cerebellum (H-ABC) is a disease that affects certain parts of the brain. Symptoms usually begin in infancy or early childhood and vary in severity; they include movement difficulties and delay in mental development or learning problems. These symptoms occur because certain brain cells in individuals with H-ABC are not fully covered by myelin (hypomyelination), a substance that usually surrounds nerve cells to help them work better. Also, this condition causes the breakdown (atrophy) of two parts of the brain that help to coordinate movement - the basal ganglia and cerebellum. H-ABC is is caused by a mutation in the TUBB4A gene. | |

What causes Hypomyelination with atrophy of basal ganglia and cerebellum ? | What causes hypomyelination with atrophy of basal ganglia and cerebellum (H-ABC)? Hypomyelination with atrophy of basal ganglia and cerebellum (H-ABC) is caused by a mutation in the TUBB4A gene. The mutation usually occurs for the first time in a family as a result of a new mutation in the affected individual. The mutation is rarely inherited from a parent. | |
How to diagnose Hypomyelination with atrophy of basal ganglia and cerebellum ? | How might hypomyelination with atrophy of basal ganglia and cerebellum (H-ABC) be diagnosed? Hypomyelination with atrophy of basal ganglia and cerebellum (H-ABC) is diagnosed by a magnetic resonance imaging (MRI) scan of the brain. When the following three features are identified in the brain of an affected individuals, the diagnosis of H-ABC can be made: Decreased myelin (hypomyelination) in the brain. Myelin usually forms a protective covering around brain cells. In H-ABC, this covering is thinner than usual which makes it difficult for nerve cells to work properly. Breakdown (atrophy) of the basal ganglia, a part of the brain that directs and controls movement. Atrophy of the cerebellum, another part of the brain that controls movement. | |
What are the treatments for Hypomyelination with atrophy of basal ganglia and cerebellum ? | How might hypomelination with atrophy of basal ganglia and cerebellum (H-ABC) be treated? Unfortunately, there is no known cure for hypomyelination with atrophy of basal ganglia and cerebellum (H-ABC). However, there is a case report of one patient's movement difficulties improving somewhat after he took the medication levodopa-carbidopa. Another patient showed improvement in movement symptoms after taking folinic acid supplements. | |
What is (are) Microcystic adnexal carcinoma ? | Microcystic adnexal carcinoma is a rare tumor of the skin that most often develops in the head and neck region, particularly in the middle of the face, though it may occur in the skin of other parts of the body as well. The average age of diagnosis is 56. This tumor is often first noticed as a bump or yellowish spot in the skin. Though microcystic adnexal carcinomas frequently grow into and disturb nearby tissues and is therefore considered an invasive cancer, this type of tumor rarely spreads to more distant parts of the body (metastasizes). The main treatment for microcystic adnexal carcinoma is Mohs micrographic surgery, which is thought to improve the chances that all of the tumor cells are removed during surgery. | |
What are the symptoms of Microcystic adnexal carcinoma ? | What are the symptoms of microcystic adnexal carcinoma? Microcystic adnexal carcinoma appears as a smooth bump or patch that is slightly raised from the surrounding skin. It may be flesh-colored or yellowish, and it increases in size over time. A microcystic adnexal carcinoma may grow into nerves nearby, which can cause discomfort, numbness, tingling (paresthesia), burning, or itching. | |
What are the treatments for Microcystic adnexal carcinoma ? | Is radiation therapy a recommended treatment for microcystic adnexal carcinoma? Unfortunately, because microcystic adnexal carcinoma is a rare cancer, there is currently not enough information to determine if radiation therapy is an effective treatment for this disease. There are no guidelines for the use of radiation therapy as treatment for microcystic adnexal carcinoma, and little is known about the dose of radiation that might be needed to be effective. Two articles studying a total of 17 patients receiving radiation therapy for microcystic adnexal carcinoma have suggested that there may be a benefit of radiation therapy for decreasing the chances of the tumor regrowing (recurrence), and the authors suggest that this treatment could be considered if there is evidence that cancer cells remain after surgery, or in situations where additional surgery cannot be done. However, another article raises concerns about the use of radiation therapy considering the small number of patients studied, the report of one patient's disease potentially worsening after radiation therapy, and the belief that exposure to radiation may be a risk factor for the initial development of this tumor. | |
What is (are) Cutaneous mastocytosis ? | Cutaneous mastocytosis is a form of mastocytosis that primarily affects the skin. There are three main forms of the condition: maculopapular cutaneous mastocytosis (also called urticaria pigmentosa), solitary cutaneous mastocytoma, and diffuse cutaneous mastocytosis. There is also an exteremely rare form called telangiectasia macularis eruptiva perstans. The signs, symptoms and severity of the condition vary by subtype. Cutaneous mastocytosis is usually caused by changes (mutations) in the KIT gene. Most cases are caused by somatic mutations which are not inherited or passed on to the next generation. However, it can rarely affect more than one family member and be inherited in an autosomal dominant manner. Treatment is usually symptomatic and may include oral antihistamines, topical steroids, and/or photochemotherapy. | |
What are the symptoms of Cutaneous mastocytosis ? | What are the signs and symptoms of Cutaneous mastocytosis? Cutaneous mastocytosis is a form of mastocytosis that primarily affects the skin. There are three main forms that vary in severity: maculopapular cutaneous mastocytosis (also called urticaria pigmentosa), solitary cutaneous mastocytoma, and diffuse cutaneous mastocytosis. There is also an exteremely rare form called telangiectasia macularis eruptiva perstans. Maculopapular cutaneous mastocytosis, the most common form of cutaneous mastocytosis, is characterized by itchy, brown patches on the skin. Although these patches may be mistaken for freckles or bug bites initially, they typically persist and gradually increase in number over several months to years. In young children, the patches may form a blister if itched or rubbed. Itching may worsen with changes in temperature, strenuous activity, emotional stress, and/or certain medications. Maculopapular cutaneous mastocytosis is most commonly seen in infants and young children and often fades by the teenaged years. In some cases, this condition may not develop until adulthood. These later onset cases generally last long-term and are more likely to progress to systemic mastocytosis. Solitary cutaneous mastocytoma is a localized form of cutaneous mastocytosis. Like maculopapular cutaneous mastocytosis, this form is typically diagnosed in young children. However, it is characterized by an itchy area of reddish or brown skin that is often thickened. When itched, these patches of skin may swell, redden, and/or blister. This form typically resolves spontaneously with age. Diffuse cutaneous mastocytosis, the most severe form of cutaneous mastocytosis, usually develops in infancy. Unlike the other forms of cutaneous mastocytosis, it affects most or all of the skin rather than appearing as distinct patches. In people affected by this condition, the skin is leathery and thickened. It may appear normal, yellowish-brown, or red in color. In some cases, there may also be widespread blistering. Additional symptoms may include hypotension, diarrhea, gastrointestinal bleeding, reddening of the skin (flushing), and anaphylactic shock. The rarest form of cutaneous mastocytosis is called telangiectasia macularis eruptiva perstans. Unlike the other forms of cutaneous mastocytosis, this form is primarily diagnosed in adults and is generally not associated with pruritus and blistering. People affected by this condition have persistent brown patches of skin and extensive telegiactasia. Rarely, this form may progress to systemic mastocytosis. The Human Phenotype Ontology provides the following list of signs and symptoms for Cutaneous mastocytosis. If the information is available, the table below includes how often the symptom is seen in people with this condition.

In these cases, the sign or symptom may be rare or common. | |
What causes Cutaneous mastocytosis ? | What causes cutaneous mastocytosis? Most cases of cutaneous mastocytosis are caused by changes (mutations) in the KIT gene. This gene encodes a protein that helps control many important cellular processes such as cell growth and division; survival; and movement. This protein is also important for the development of certain types of cells, including mast cells (immune cells that are important for the inflammatory response). Certain mutations in the KIT gene can leads to an overproduction of mast cells. In cutaneous mastocytosis, excess mast cells accumulate in the skin, leading to the many signs and symptoms of the condition. | |
Is Cutaneous mastocytosis inherited ? | Is cutaneous mastocytosis inherited? Most cases of cutaneous mastocytosis are not inherited. They occur spontaneously in families with no history of the condition and are due to somatic changes (mutations) in the KIT gene. Somatic mutations occur after conception and are only present in certain cells. Because they are not present in the germ cells (egg and sperm), they are not passed on to the next generation. Cutaneous mastocytosis can rarely affect more than one family member. In these cases, the condition is typically inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. A person with familial cutaneous mastocytosis has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Cutaneous mastocytosis ? | How is cutaneous mastocytosis diagnosed? A diagnosis of cutaneous mastocytosis is typically suspected based on the presence of suspicious signs and symptoms. A skin biopsy that reveals a high number of mast cells (immune cells that are important for the inflammatory response) confirms the diagnosis. Unfortunately it can sometimes be difficult to differentiate cutaneous mastocytosis from systemic mastocytosis. Additional tests may, therefore, be ordered to further investigate the risk for systemic disease. A bone marrow biopsy and specialized blood tests may be recommended in adults with cutaneous mastocytosis since they are at a higher risk for systemic mastocytosis. Affected children typically do not undergo a bone marrow biopsy unless blood tests are abnormal. | |
What are the treatments for Cutaneous mastocytosis ? | How might cutaneous mastocytosis be treated? Although there is currently no cure for cutaneous mastocytosis, treatments are available to manage the symptoms of the condition. In general, it is recommended that affected people avoid things that trigger or worsen their symptoms when possible. Certain medications such as oral antihistamines and topical steroids are often prescribed to relieve symptoms. Affected adults may also undergo photochemotherapy which can help alleviate itching and improve the appearance of the patches; however, the condition is likely to recur within six to twelve months of the last treatment. People at risk for anaphylactic shock and/or their caregivers should be trained in how to recognize and treat this life-threatening reaction and should carry an epinephrine autoinjector at all times. | |
What is (are) Neuronal ceroid lipofuscinosis 5 ? | Neuronal ceroid lipofuscinosis 5 (CLN5-NCL) is a rare condition that affects the nervous system. Signs and symptoms of the condition generally develop between ages 4.5 and 7 years, although later onset cases have been reported. Affected people may experience loss of muscle coordination (ataxia), seizures that do not respond to medications, muscle twitches (myoclonus), visual impairment, and cognitive/motor decline. It occurs predominantly in the Finnish population. CLN5-NCL is caused by changes (mutations) in the CLN5 gene and is inherited in an autosomal recessive manner. Treatment options are limited to therapies that can help relieve some of the symptoms. | |

What is (are) Permanent neonatal diabetes mellitus ? | Permanent neonatal diabetes mellitus (PNDB) is a type of diabetes that appears within the first 6 months of life and persists throughout life. Affected individuals have slow growth before birth followed by hyperglycemia, dehydration and failure to thrive in infancy. Some individuals also have neurological problems including developmental delay and epilepsy; when these problems are present with PNDB, it is called DEND syndrome. A few individuals with PNDB also have an underdeveloped pancreas and may have digestive problems. PNDB is caused by mutations in any one of several genes (some of which have not yet been identified) including the KCNJ11, ABCC8, and INS genes. It may be inherited in an autosomal recessive or autosomal dominant manner. Treatment includes rehydration, insulin therapy and/or long-term therapy with oral sulfonylureas (in some cases). | |

What is (are) Spastic diplegia cerebral palsy ? | Spastic diplegia cerebral palsy is a form of cerebral palsy, a neurological condition that usually appears in infancy or early childhood and permanently affects muscle control and coordination. Affected people have increased muscle tone which leads to spasticity (stiff or tight muscles and exaggerated reflexes) in the legs. The arm muscles are generally less affected or not affected at all. Other signs and symptoms may include delayed motor or movement milestones (i.e. rolling over, sitting, standing); walking on toes; and a "scissored" gait (style of walking). It occurs when the portion of the brain that controls movement is damaged or develops abnormally. The exact underlying cause is often unknown; however, the condition has been associated with genetic abnormalities; congenital brain malformations; maternal infections or fevers; and/or injury before, during or shortly after birth. There is no cure, and treatment options vary depending on the signs and symptoms present in each person and the severity of the condition. | |
What are the symptoms of Spastic diplegia cerebral palsy ? | What are the signs and symptoms of spastic diplegia cerebral palsy? The symptoms and severity of spastic diplegia cerebral palsy vary significantly from person to person. It is a form of cerebral palsy, a neurological condition that usually appears in infancy or early childhood and permanently affects muscle control and coordination. Affected people have increased muscle tone which leads to stiff or tight muscles and exaggerated reflexes (spasticity). Other signs and symptoms may include delayed motor or movement milestones (i.e. rolling over, sitting, standing); walking on toes; and a "scissored" gait (style of walking). Although symptoms may change as a person gets older, the condition does not get worse over time (progress). Cerebral palsy, including spastic diplegia cerebral palsy, can be associated with a variety of other health problems, including: Intellectual disability Learning disabilities Seizures Delayed growth Spinal abnormalities Osteoarthritis Impaired vision Hearing loss Speech and language disorders Poor bladder control Contractures | |
What causes Spastic diplegia cerebral palsy ? | What causes spastic diplegia cerebral palsy? Spastic diplegia cerebral palsy occurs when the portion of the brain that controls movement is damaged or develops abnormally. This usually occurs before birth, but can happen at any time while the brain is still developing (usually before age 2). In many cases, the exact underlying cause is unknown; however, the condition has been associated with genetic abnormalities; congenital brain malformations; maternal infections or fevers; injury before, during or shortly after birth; problems with blood flow to the brain; and severe lack of oxygen to the brain. The following medical conditions or events may increase the risk for a child to be born with or develop cerebral palsy: Premature birth Low birth weight (less than 5 and a half pounds) Mothers with infections or high fevers during pregnancy Multiple births (twins, triplets and other multiples) Rh incompatibility (blood type incompatibility between mother and child) Mothers with thyroid abnormalities, intellectual disability, excess protein in the urine, or seizures Breech presentation Complicated labor and delivery Low Apgar score Newborn jaundice | |
Is Spastic diplegia cerebral palsy inherited ? | Is spastic diplegia cerebral palsy inherited? Scientists have found that family members of people with cerebral palsy, including spastic diplegia cerebral palsy, have an increased risk of developing the condition. The exact risk depends on the how closely the family members are related: A child with a sibling (brother, sister) or parent with cerebral palsy would have a six- to nine-fold increased risk of developing the condition (actual risk: 1 to 1.5%) A child with a half sibling with cerebral palsy would have up to a three-fold risk of developing the condition (actual risk: less than 1%) A child with a first cousin with cerebral palsy would have a 1.5-fold increased risk of developing the condition (actual risk: less than 1%) This suggests that there may be a genetic component in some cases of cerebral palsy. However, the inheritance is likely multifactorial which means the condition is caused by multiple genes interacting with each other and with environmental factors. | |
How to diagnose Spastic diplegia cerebral palsy ? | How is spastic diplegia cerebral palsy diagnosed? A diagnosis of spastic diplegia cerebral palsy is based on the presence of characteristic signs and symptoms. However, the following tests may be recommended to rule out other conditions that cause similar features. Blood tests CT scan of the head MRI scan of the head Electroencephalogram (EEG) Electromyography For more information about the diagnosis of spastic diplegia cerebral palsy and other types of cerebral palsy, please click here. | |
What are the treatments for Spastic diplegia cerebral palsy ? | How might spastic diplegia cerebral palsy be treated? Treatment of spastic diplegia cerebral palsy varies based on the signs and symptoms present in each person and the severity of the condition. Affected people are often cared for by a team of healthcare providers who specialize in a variety of different medical fields (i.e. neurologists, rehabilitation physicians, social workers, physical therapists, etc). Orthotic devices (such as a walker, wheelchair or leg braces), physical therapy, and occupational therapy can help improve independent mobility. Certain medications may be prescribed to relax stiff, contracted, or overactive muscles. Orthopedic surgery is often recommended for severely affected people who have symptoms that make walking and moving difficult or painful.

What is (are) Necrotizing fasciitis ? | Necrotizing fasciitis is a serious infection of the skin, subcutaneous tissue (tissue just beneath the skin) and fascia. The infection can arise suddenly and spread quickly. Necrotizing fasciitis can be caused by several different types of bacteria. Early signs include flu-like symptoms and redness and pain around the infection site. If the infection is not treated promptly, it can lead to multiple organ failure and death. As a result, prompt diagnosis and treatment is essential. Treatment typically includes intravenous antibiotics and surgery to remove infected and dead tissue. | |
What are the symptoms of Necrotizing fasciitis ? | What are the signs and symptoms of necrotizing fasciitis? Symptoms often begin within hours of an injury. Intense pain and tenderness over the affected area are often considered the hallmark symptoms of necrotizing fasciitis (NF). The pain is often described as severe and may raise suspicion of a torn muscle. Some early symptoms may be mistaken for the flu and can include fever, sore throat, stomach ache, nausea, diarrhea, chills, and general body aches. The patient may notice redness around the area which spreads quickly; the affected area can eventually become swollen, shiny, discolored, and hot to the touch. In addition, there may be ulcers or blisters. If the infection continues to spread, the patient may experience the following: dehydration, high fever, fast heart rate, and low blood pressure. Pain may actually improve as tissues and the nerves are destroyed. As the infection spreads, vital organs may be affected and the patient may become confused or delirious. If not successfully treated, NF can lead to shock and eventual death. | |
What causes Necrotizing fasciitis ? | What causes necrotizing fasciitis? Bacteria that can cause necrotizing fasciitis (NF) include the following: Klebsiella, Clostridium, and Escherichia coli; group A Streptococcus is the most common cause. Anyone can develop NF. Approximately 50% of necrotizing fasciitis cases caused by streptococcal bacteria occur in young and otherwise healthy individuals. Although necrotizing fasciitis most frequently develops after trauma that causes a break in the skin, it can also develop after minor trauma that occurs without a break in the skin. NF can occur as a complication of a surgical procedure; it can also occur at the site of a relatively minor injury such as an insect bite or an injection. In addition, underlying illnesses which weaken the immune system may increase the risk that a person will develop NF. Studies have even suggested a possible relationship between the use of nonsteroidal anti-inflammatory medications (NSAIDs) during varicella infections and the development of necrotizing fasciitis. | |
What are the treatments for Necrotizing fasciitis ? | How might necrotizing fasciitis be treated? Accurate and prompt diagnosis, treatment with intravenous (IV) antibiotics, and surgery to remove dead tissue are all important for treating necrotizing fasciitis. Since the blood supply to the infected tissue is impaired, antibiotics cannot penetrate into the infected tissue. As a result, surgery to remove the dead, damaged, or infected tissue is the cornerstone of treatment for necrotizing fasciitis. In addition, early surgical treatment may minimize tissue loss, eliminating the need for amputation of the infected extremity. The choice of antibiotics will likely depend on the particular bacteria involved. Supplemental oxygen, fluids, and medicines may be needed to raise the blood pressure. Hyperbaric oxygen therapy and intravenous immunoglobulin may also be considered, but their use in patients with NF is considered controversial by some. | |

What causes Wildervanck syndrome ? | What causes Wildervanck syndrome? The exact cause of Wildervanck syndrome is not known. It is suspected to be a polygenic condition, meaning that many genetic factors may be involved. | |
Is Wildervanck syndrome inherited ? | How is Wildervanck syndrome inherited? Wildervanck syndrome does not have a clear pattern of inheritance. In most cases, only one person in a family is affected. These cases are called isolated or sporadic because there is no family history of Wildervanck syndrome. Because this syndrome occurs mostly in females, it is possible that this condition has X-linked dominant inheritance. The lack of males with Wildervanck syndrome suggests that affected males have more severe features and do not survive to birth. | |

What is (are) Chromosome 5q deletion ? | Chromosome 5q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 5. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 5q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person. | |
What is (are) Turner syndrome ? | Turner syndrome is a chromosomal disorder that affects development in females. It is characterized by a person having one X chromosome in each cell (females without Turner syndrome have two X chromosomes in each cell). Signs and symptoms may include short stature; premature ovarian failure; a "webbed" neck; a low hairline at the back of the neck; and swelling (lymphedema) of the hands and feet. Some people with Turner syndrome have skeletal abnormalities, kidney problems, and/or a congenital heart defect. Most affected girls and women have normal intelligence, but some have developmental delays, learning disabilities, and/or behavior problems. Turner syndrome is typically not inherited, but it can be inherited in rare cases. Treatment may include growth hormone therapy for short stature and estrogen therapy to help stimulate sexual development. While most women with Turner syndrome are infertile, assisted reproductive techniques can help some women become pregnant. | |
What are the symptoms of Turner syndrome ? | What are the signs and symptoms of Turner syndrome? There are various signs and symptoms of Turner syndrome, which can range from very mild to more severe. Short stature is the most common feature and usually becomes apparent by age 5. In early childhood, frequent middle ear infections are common and can lead to hearing loss in some cases. Most affected girls do not produce the necessary sex hormones for puberty, so they don't have a pubertal growth spurt, start their periods or develop breasts without hormone treatment. While most affected women are infertile, pregnancy is possible with egg donation and assisted reproductive technology. Intelligence is usually normal, but developmental delay, learning disabilities, and/or behavioral problems are sometimes present. Additional symptoms of Turner syndrome may include: a wide, webbed neck a low or indistinct hairline in the back of the head swelling (lymphedema) of the hands and feet broad chest and widely spaced nipples arms that turn out slightly at the elbow congenital heart defects or heart murmur scoliosis (curving of the spine) or other skeletal abnormalities kidney problems an underactive thyroid gland a slightly increased risk to develop diabetes, especially if older or overweight osteoporosis due to a lack of estrogen, (usually prevented by hormone replacement therapy). The Human Phenotype Ontology provides the following list of signs and symptoms for Turner syndrome. 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.

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 causes Turner syndrome ? | What causes Turner syndrome? Turner syndrome is caused by partial or complete loss of one of the X chromosomes in cells of females. Females without Turner syndrome have 2 full X chromosome in all of their cells (and males have one X chromosome and one Y chromosome). The missing genetic material affects development before and after birth. Most females with Turner syndrome are missing a full X chromosome in all of their cells (also called monosomy X). This form results from a random error in an egg or sperm cell prior to conception. Some females with Turner syndrome have two X chromosomes, but one of them is missing a piece (has a deletion). Depending on the specific gene(s) that are missing, the features of Turner syndrome may result. A deletion may occur sporadically (not inherited) or may be inherited from a parent. Mosaic Turner syndrome (when some cells have one X chromosome and some have two sex chromosomes) is caused by a random error in early fetal development (shortly after conception). It is still unclear exactly which genes on the X chromosome are associated with each feature of Turner syndrome. It is known that the SHOX gene on the X chromosome is important for growth and bone development. A missing copy of this gene is thought to result in the short stature and skeletal abnormalities in many affected women. | |
Is Turner syndrome inherited ? | Is Turner syndrome inherited? Most cases of Turner syndrome are not inherited. Most commonly, Turner syndrome occurs due to a random event during the formation of an egg or sperm cell in a parent (prior to conception). For example, if an egg or sperm cell mistakenly loses a sex chromosome, and joins at conception with an egg or sperm containing an X chromosome, the resulting child will have a single X chromosome in each cell. Mosaic Turner syndrome, occurring when a person has some cells with one X chromosome and some cells with two sex chromosomes, is also not inherited. This also occurs due to a random event, during early fetal development rather than before conception. In rare cases, Turner syndrome may be caused by a missing piece (partial deletion) of the X chromosome. A deletion can be inherited from a parent. Genetic testing of an affected fetus or child can identify the type of Turner syndrome present and may help to estimate the risk of recurrence. People with questions about genetic testing or recurrence risks for Turner syndrome are encouraged to speak with a genetic counselor or other genetics professional. | |
What is (are) Chiari malformation ? | Chiari malformations are structural defects in the cerebellum, the part of the brain that controls balance. When the indented bony space at the lower rear of the skull is smaller than normal, the cerebellum and brainstem can be pushed downward. The resulting pressure on the cerebellum can block the flow of cerebrospinal fluid (the liquid that surrounds and protects the brain and spinal cord) and can cause a range of symptoms including dizziness, muscle weakness, numbness, vision problems, headache, and problems with balance and coordination. Treatment may require surgery. Many patients with the more severe types of Chiari malformations who undergo surgery see a reduction in their symptoms and/or prolonged periods of relative stability, however paralysis is generally permanent despite surgery. There are four types of Chiari malformations. The types tend to correspond with the degree of severity, with type 1 being the most common and least severe. Some people with type 1 have no symptoms and do not require treatment. Chiari malformation type 1 Chiari malformation type 2 Chiari malformation type 3 Chiari malformation type 4 | |

What is (are) Neuronal ceroid lipofuscinosis 9 ? | Neuronal ceroid lipofuscinosis 9 (CLN9-NCL) is a rare condition that affects the nervous system. Signs and symptoms of the condition generally develop in early childhood (average age 4 years) and may include loss of muscle coordination (ataxia), seizures that do not respond to medications, muscle twitches (myoclonus), visual impairment, and developmental regression (the loss of previously acquired skills). The underlying genetic cause of CLN9-NCL is unknown but it appears to be inherited in an autosomal recessive manner. Treatment options are limited to therapies that can help relieve some of the symptoms. | |

What is (are) Goldberg-Shprintzen megacolon syndrome ? | Goldberg-Shprintzen megacolon syndrome is a very rare genetic condition characterized by Hirschsprung disease, megacolon, small head, widely spaced eyes, cleft palate, short stature, and learning disability. This condition has been described in about 15 individuals to date. Some of the reported cases also had iris coloboma, hypotonia, epilepsy, and ptosis. One of the described patients had sparse scalp hair, a sloping forehead, sparse eyebrows, broad nasal bridge, large ears, pointed chin, ventricular septal defect, hypospadias, syndactyly between the second and third fingers, and clubfeet. This condition appears to be inherited as an autosomal recessive trait and was found to be caused by mutations in the KIAA1279 gene. | |

What is (are) Gardner-Diamond syndrome ? | Gardner-Diamond syndrome (GDS) is a rare condition characterized by episodes of unexplained, painful bruising that mostly occurs on the arms, legs, and/or face. It is most common in Caucasian women who have mental illness or emotional stress. Symptoms typically include the formation of multiple, small, purple bruises that may be associated with burning, redness and swelling. Most affected people report that the bruising occurs either spontaneously, or some time after trauma or surgery at other sites of the body. The cause of GDS is poorly understood. Management typically involves psychiatric treatment. | |
What are the symptoms of Gardner-Diamond syndrome ? | What are the signs and symptoms of Gardner-Diamond syndrome? People with Gardner-Diamond syndrome have reported that bruises occur either spontaneously or after trauma or surgery (even at other sites of the body). Some people are able to pinpoint exactly when the bruising occurred, while others are not. Episodes of bruising may begin with sensations such as burning, stinging or pain, and may be accompanied by a general feeling of malaise or fatigue. This may be followed by warmth, puffiness, redness and/or itching over the affected area. In some cases, episodes may also be accompanied by fever, headache, or gastrointestinal symptoms. Sometimes, pain and swelling is severe enough to cause immobilization of the affected body part. People have reported that the pain generally subsides when the bruises appear. Bruises typically go away in approximately 7-10 days. However, relapses and remissions of bruising episodes can last for many years. In some cases, symptoms of the condition persist and may worsen. Subsequent episodes are most likely to occur after some sort of physical trauma or stress. | |
What causes Gardner-Diamond syndrome ? | What causes Gardner-Diamond syndrome? The underlying cause of Gardner-Diamond syndrome (GDS) is poorly understood and has not been identified. Experts have proposed several possible explanations including: response to stress - stress, or distress, is associated with increased levels of glucocorticoids and catecholamines in the body, which may alter processes such as fibrinolysis (the breakdown of blood clots) increased fibrinolysis - an increase in the activity of tissue plasminogen activator (tPA), which can cause a cascade of events that may lead to bleeding autoerythrocyte sensitization - an autoimmune reaction to the affected person's own red blood cells (erythrocytes) | |
How to diagnose Gardner-Diamond syndrome ? | How is Gardner-Diamond syndrome diagnosed? There are no specific laboratory tests that can confirm the diagnosis of Gardner-Diamond syndrome (GDS), but various tests may be used to rule out other conditions. The diagnosis may be considered based on the presence of symptoms, when all other causes of bleeding have been ruled out (including the use or misuse of various medications that may be associated with bleeding). A detailed psychiatric evaluation is of huge importance if GDS is suspected, with information concerning how the person has responded to major stressful events in his or her life (such as fetal losses, death in the family, divorce, loss of income). While the underlying cause of GDS is unknown, an abnormal psychiatric history is virtually always present. | |
What are the treatments for Gardner-Diamond syndrome ? | How might Gardner-Diamond syndrome be treated? There is no specific treatment for Gardner-Diamond syndrome (GDS). It has been suggested that psychiatric treatment (including psychotherapy) is the only reasonable therapeutic option. In some people, psychiatric medications for mental illness have helped to improve the symptoms. For example, in a person with GDS and an underlying personality disorder, medications used to treat the personality disorder may help with the symptoms of GDS. Due to the presumed psychological nature of the disease, placebo effect has been used successfully to ease the severity of symptoms. It has been proposed that certain medications used to alter the tonus of the capillaries (how they contract), the permeability of the vessels, and/or the flowing properties of the blood may be useful for some people. Symptomatic therapy may be helpful for severe, general symptoms. Several approaches including antihistamines, corticosteroids, antidepressants, hormones, and vitamins have had variable success. | |
What is (are) Mosaic trisomy 9 ? | Mosaic trisomy 9 is a chromosomal abnormality that can affect may parts of the body. In people affected by this condition, some of the body's cells have three copies of chromosome 9 (trisomy), while other cells have the usual two copies of this chromosome. The signs and symptoms vary but may include mild to severe intellectual disability, developmental delay, growth problems (both before and after birth), congenital heart defects, and/or abnormalities of the craniofacial (skull and face) region. Most cases are not inherited; it often occurs sporadically as a random event during the formation of the reproductive cells (egg and sperm) or as the fertilized egg divides. Treatment is based on the signs and symptoms present in each person. | |
What are the symptoms of Mosaic trisomy 9 ? | What are the signs and symptoms of mosaic trisomy 9? The signs and symptoms of mosaic trisomy 9 vary but may include: Different degrees of developmental delay and intellectual disability Abnormal growth including low birth weight, failure to thrive, hypotonia (low muscle tone), and short stature Characteristic craniofacial features such as microcephaly (unusually small head); a sloping forehead with narrow temples; a broad nose with a bulbous tip and "slitlike" nostrils; a small jaw; abnormally wide fontanelles at birth; cleft lip and/or palate; low-set, misshapen ears; microphthalmia (unusually small eyes) and/or short, upwardly slanting eyelid folds (palpebral fissures) Vision problems Congenital heart defects Abnormalities of the muscles and/or bones such as congenital dislocation of the hips; abnormal position and/or limited function of the joints; underdevelopment of certain bones; and/or abnormal curvature of the spine Unusually formed feet, such as club foot or "rocker bottom" feet Abnormalities of the male reproductive system, including undescended testes, a small penis, and/or abnormal placement of the urinary opening Kidney problems Brain malformations such as hydrocephalus and/or Dandy-Walker malformation | |
What causes Mosaic trisomy 9 ? | What causes mosaic trisomy 9? Most cases of mosaic trisomy 9 occur due to a random event during the formation of the reproductive cells (egg and sperm) or after fertilization has taken place. An error in cell division (called nondisjunction) may cause some eggs or sperm to have an abnormal number of chromosomes. If an egg or sperm with an extra chromosome 9 contributes to the genetic makeup of an embryo, the embryo will have an extra copy of chromosome 9 in each cell. As the embryo grows and divides, an attempt may be made to correct the mistake by eliminating one extra chromosome 9. In people with mosaic trisomy 9, this attempt may be partly successful, leaving some cells with an extra chromosome 9 and some cells with the extra chromosome deleted (the usual chromosome number). This correction process is called trisomy rescue. In other cases, the egg and sperm may have a normal number of chromosomes, but an error of cell division (nondisjunction) occurs when the fertilized egg is growing and dividing. If an error occurs during one of the divisions, it can cause some cells to have an abnormal number of chromosomes. In people affected by mosaic trisomy 9, some of the body's cells have the usual two copies of chromosome 9, and other cells have three copies of this chromosome (trisomy). The percentage of cells with trisomy 9 and which parts of the body are affected vary from person to person. This leads to variability in the range and severity of symptoms. In rare cases, mosaic trisomy 9 is inherited from a parent with a chromosomal rearrangement called a "pericentric inversion." This occurs when a segment of chromosome 9 has broken off in two places, swiveled round 180 degrees and reinserted itself into the chromosome. If this rearrangement is considered "balanced," meaning the piece of chromosome is in a different order but no genetic material is gained or lost, it usually does not cause any symptoms or health problems. However, it can be associated with an increased risk of having children with an abnormal number or chromosomes. | |

How to diagnose Mosaic trisomy 9 ? | How is mosaic trisomy 9 diagnosed? In some cases, mosaic trisomy 9 is diagnosed before birth. A pregnancy ultrasound may reveal signs and symptoms that are suggestive of a chromosomal or developmental disorder. Additional tests, such as chorionic villus sampling (CVS) or an amniocentesis, may be offered to further investigate these features. During a CVS, a tissue sample from a portion of the placenta is removed and analyzed, while amniocentesis involves the removal of a sample of fluid that surrounds the developing baby. In both tests, the fluid or tissue sample is used to obtain a picture of the baby's chromosomes, which is called a karyotype. This may reveal mosaic trisomy 9. In other cases, the child is not diagnosed until after birth. Mosaic trisomy 9 may be suspected after characteristic signs and symptoms are identified on physical exam. A diagnosis can be confirmed by examining the child's chromosomes from a sample of blood. | |
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. | |

What is (are) Lymphedema-distichiasis syndrome ? | Lymphedema distichiasis syndrome is a condition that affects the normal function of the lymphatic system (part of the immune system that produces and transports fluids and immune cells throughout the body). People with this condition are born with extra eyelashes (distichiasis) and develop puffiness or swelling (lymphedema) of the limbs by the time they are in their forties. The abnormal eyelashes, which grow along the inner lining of the eyelid, often touch the eyeball and can cause damage to the clear covering of the eye (cornea). Other eye problems such as an irregular curvature of the cornea causing blurred vision (astigmatism) or scarring of the cornea may also occur. Other health problems, varicose veins, droopy eyelids (ptosis), heart abnormalities, and an opening in the roof of the mouth (a cleft palate), may also be present. Lymphedema-distichiasis syndrome is caused by mutations in the FOXC2 gene. This condition is inherited in an autosomal dominant pattern. | |

What is (are) Bronchiolitis obliterans ? | Bronchiolitis obliterans is an inflammatory obstruction of the lung's tiniest airways, the bronchioles. The bronchioles may become damaged and inflamed after inhalation of toxic fumes, as a result of respiratory infections, in association with connective tissue disorders, or after bone marrow or heart-lung transplants. This leads to extensive scarring that blocks the airways, leading to a dry cough, shortness of breath, fatigue and wheezing in the absence of a cold or asthma. While there is no way to reverse the disease, treatments are available to stabilize or slow the progression. Another similarly named disease, bronchiolitis obliterans organizing pneumonia, is a completely different disease. | |
What are the symptoms of Bronchiolitis obliterans ? | What are the signs and symptoms of bronchiolitis obliterans? Bronchiolitis obliterans is characterized by a dry cough and shortness of breath which develop 2 to 8 weeks after toxic fume exposure or a respiratory illness. Fatigue and wheezing in the absence of a cold or asthma may also be noted. While high resolution chest CT scans and pulmonary function tests may help to detect bronchiolitis obliterans, a surgical lung biopsy is the most definitive way to diagnose the disease. | |
