<s>[INST] What are the symptoms of 21-hydroxylase deficiency ? [/INST] What are the signs and symptoms of 21-hydroxylase deficiency? Symptoms can vary greatly from patient to patient with 21-hydroxylase deficiency, as a result distinct forms of this deficiency have been recognized. Three common forms include classical salt wasting, simple virilizing, and nonclassical. The Human Phenotype Ontology provides the following list of signs and symptoms for 21-hydroxylase deficiency. 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 the thorax - Adrenal hyperplasia - Adrenogenital syndrome - Autosomal recessive inheritance - Fever - Growth abnormality - Gynecomastia - Hypertension - Hypoglycemia - Hypospadias - Renal salt wasting - 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 symptoms of classical salt wasting 21-hydroxylase-deficient congenital adrenal hyperplasia? The classical salt wasting form of 21-hydroxylase-deficient is a severe form of 21-hydroxylase deficiency. People with this condition have no 21-hydroxylase function.Within the first week of life newborns may have life threatening salt-wasting crises and low blood pressure. Females are often born with ambiguous genitalia. A close look at the hormone levels in patients with this form of 21-hydroxylase deficiency reveals an increased level of testosterone and rennin, and reduced levels of cortisol and aldosterone. Levels of 17-hydroxyprogesterone is over 5,000 nmol/L. What are the symptoms of simple virilizing 21-hydroxylase-deficient congenital adrenal hyperplasia? Patients with simple virilizing 21-hydroxylase-deficient congenital adrenal hyperplasia have some functioning 21-hydroxylase (about 1%). Females may be born with clitoral enlargement, labial fusion, and sexual ambiguity. Males may present in early childhood with signs of precocious puberty such as very early sexual development, pubic hair development, and/or growth acceleration. Untreated patients have a shorter than average adult height. A close look at hormone levels in patients with simple virilizing 21-hydroxylase deficiency reveal an increased level of testosterone, reduced level of cortisol, normal or increased level of renin, and normal levels of aldosterone. Levels of 17-Hydroxyprogesterone are 2500 to 5000 nmol/L. What are the symptoms of nonclassical 21-hydroxylase-deficient congenital adrenal hyperplasia? People with nonclassical or late-onset 21-hydroxylase-deficient congenital adrenal hyperplasia have 20% to 50% of 21-Hydroxylase activity. They may present in childhood or adulthood with early pubic hair growth or with symptoms of polycystic ovary syndrome. In females symptoms may include excessive hair growth, absent periods, infertility, androgenic alopecia, masculinized genitalia, and acne. Height is likely to be normal. A close look at the hormone levels in patients with the nonclassical type reveal a variably increased level of testosterone and normal levels of aldosterone, renin, and cortisol. Levels of 17-Hydroxyprogesterone are 500 to 2500 nmol/L. </s></s>

<s>[INST] What causes 21-hydroxylase deficiency ? [/INST] What causes salt-wasting, simple virilizing, and nonclassical 21-hydroxylase-deficient congenital adrenal hyperplasia? Salt-wasting, simple virilizing, and late-onset 21-hydroxylase deficiency are all caused by mutations in the human 21-hydroxylase gene (CYP21A2). </s></s>

<s>[INST] Is 21-hydroxylase deficiency inherited ? [/INST] How is 21-hydroxylase-deficient congenital adrenal hyperplasia passed through families? 21-hydroxylase-deficient congenital adrenal hyperplasia has an autosomal recessive pattern of inheritance. In autosomal recessive conditions, both parents carry one copy of a mutated gene for the disorder. They have a 25 percent chance with each pregnancy of having a child affected by the disorder. The chance with each pregnancy of having an unaffected child who is a carrier of the disorder is 50 percent, and the chance that a child will not have the disorder and will not be a carrier is 25 percent. See the illustration below. </s></s>

<s>[INST] How to diagnose 21-hydroxylase deficiency ? [/INST] Is genetic testing for 21-hydroxylase-deficient congenital adrenal hyperplasia available? Yes.

<s>[INST] What are the treatments for 21-hydroxylase deficiency ? [/INST] What is the goal for treating 21-hydroxylase-deficient congenital adrenal hyperplasia? The objectives for treating 21-hydroxylase deficiency differ with age. In childhood, the overall goal is to replace cortisol. Obtaining hormonal balance is important and patients growth velocity and bone age is monitored. Routine analysis of blood, urine, and/or saliva may also be necessary. Corrective surgery is frequently required for females born with abnormal genitalia. In late childhood and adolescence, maintaining hormonal balance is equally important. Overtreatment may result in obesity and delayed menarche/puberty, whereas under-replacement will result in sexual precocity. Also, it is important that teens and young adults with 21-hydroxylase deficiency be successfully transitioned to adult care facilities. Follow-up of adult patients should involve multidisciplinary clinics. Problems in adult women include fertility concerns, excessive hair growth, and menstrual irregularity; obesity and impact of short stature; sexual dysfunction and psychological problems. Counseling may be helpful. Adult males may develop enlargement of the testes and if so, should work with an endocrinologist familiar with the management of patients with this deficiency. </s></s>

<s>[INST] What is (are) Pendred syndrome ? [/INST] Pendred syndrome is a condition usually characterized by sensorineural hearing loss in both ears (bilateral) and euthyroid goiter (enlargement of the thyroid gland with normal thyroid gland function). The amount of hearing loss varies among affected people. In many cases, significant hearing loss is present at birth. In other cases, hearing loss does not develop until later in infancy or childhood. Some people have problems with balance caused by dysfunction of the part of the inner ear that helps with balance and orientation (the vestibular system). Pendred syndrome is inherited in an autosomal recessive manner. Mutations in 3 genes are currently known to cause the condition (SLC26A4, FOXI1, and KCNJ10) and are found in about half of affected people. Other genes responsible for the condition have not yet been identified. </s></s>

<s>[INST] Is Pendred syndrome inherited ? [/INST] How is Pendred syndrome inherited? Pendred syndrome is inherited in an autosomal recessive manner. For most autosomal recessive conditions, a person must have 2 changed (mutated) copies of the responsible gene in each cell in order to have the condition. One changed copy of the responsible gene is usually inherited from each parent; the parents are referred to as carriers. Carriers typically do not have signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% chance to not be a carrier and not have the condition. Pendred syndrome can be caused either by having mutations in both copies of the SLC26A4 gene (more commonly), or by having one mutation in the SLC26A4 gene and one mutation in another gene. </s></s>

<s>[INST] What is (are) Methylmalonic acidemia with homocystinuria, type cblC ? [/INST] Methylmalonic academia with homocystinuria (MMA+HCU) cblC is a genetic disorder that prevents the body from breaking down certain amino acids found in protein (i.e., isoleucine, valine, methionine, and threonine). As a result, homocystine, methylmalonic acid, and other harmful substances build-up in the body. Treatment should begin as soon as possible. In general, treatment may involve a low-protein diet, medical formula/drink, regular meals, careful monitoring, and vitamin B12 shots. Most US states now offer newborn screening for MMA+HCU, allowing for early detection and treatment. However even with early treatment, most children with MMA+HCU experience some symptoms affecting vision, growth, and learning. MMA+HCU cblC type is caused by changes in the MMACHC gene. It is inherited in an autosomal recessive fashion. </s></s>

For both methylmalonic acidemia and methylmalonic acidemia with homocystinuria (MMA+HCU) cblC type signs and symptoms can vary from mild to life-threatening. There have been cases of MMA+HCU cblC type associated with mild symptoms and delayed age at onset (teen to adult years). In most cases however, signs and symptoms of MMA+HCU cblC type present in infancy. Even with early diagnosis and treatment, children with the condition tend to have symptoms affecting vision, growth, and learning. A recent study of 12 children with early onset MMA+HCU CblC type, diagnosed by newborn screening, and treated early with intramuscular hydroxocobalamin, oral betaine, folinic acid, l-carnitine, and dietary protein modification were reported to have developed the following symptoms: Mild to moderate low muscle tone (91%) Quick uncontrollable movements of the eye (nystagmus) with variable affect on vision (75%) Seizure (25%) Small head circumference (17%) Testing of communication, socialization, daily living skills, motor skills, and behavior showed mild to moderate delays in these areas for most children.

<s>[INST] What is (are) Craniopharyngioma ? [/INST] A craniopharyngioma is a slow-growing benign tumor that develops near the pituitary gland (a small endocrine gland at the base of the brain) and the hypothalamus (a small cone-shaped organ connected to the pituitary gland by nerves). This tumor most commonly affects children between 5 and 10 years of age; however, adults can sometimes be affected. Craniopharyngiomas are thought to arise from remnants of the craniopharyngeal duct and/or Rathke cleft or from metaplasia (abnormal transformation of cells) of squamous epithelial cell remnants of the stomadeum.[orphanet] Craniopharyngioma is treated with surgery alone or by surgery followed by radiation. </s></s>

<s>[INST] What are the symptoms of Craniopharyngioma ? [/INST] What symptoms may be associated with craniopharyngioma? Craniopharyngioma causes symptoms in three different ways: by increasing the pressure on the brain (intracranial pressure) by disrupting the function of the pituitary gland by damaging the optic nerve Increased pressure on the brain causes headache, nausea, vomiting (especially in the morning), and difficulty with balance. Damage to the pituitary gland causes hormone imbalances that can lead to excessive thirst and urination (diabetes insipidus) and stunted growth. When the optic nerve is damaged by the tumor, vision problems develop. These defects are often permanent, and may be worse after surgery to remove the tumor. Most patients have at least some visual defects and evidence of decreased hormone production at the time of diagnosis. </s></s>

<s>[INST] What causes Craniopharyngioma ? [/INST] What causes craniopharyngioma? Craniopharyngiomas are thought to arise from epithelial remnants of the craniopharyngeal duct or Rathke's pouch (adamantinomatous type tumours) or from metaplasia of squamous epithelial cell rests that are remnants of the part of the stomadeum that contributed to the buccal mucosa (squamous papillary type tumours). </s></s>

<s>[INST] What are the treatments for Craniopharyngioma ? [/INST] How might craniopharyngiomas be treated? Traditionally, surgery has been the main treatment for craniopharyngioma. However, radiation treatment instead of surgery may be the best choice for some patients. In tumors that cannot be removed completely with surgery alone, radiation therapy is usually necessary. If the tumor has a classic appearance on CT scan, then even a biopsy may not be necessary, if treatment with radiation alone is planned. This tumor is best treated at a center with experience managing craniopharyngiomas. </s></s>

While nephrocalcinosis is a relatively rare complication (5%), primary hyperparathryroidism is relatively common, especially in the elderly. Rarely, hyperparathyroidism can be associated with multiple endocrine neoplasia type 1 (MEN1). Distal renal tubular acidosis (RTA) is the second most common cause of medullary nephrocalcinosis. hypervitaminosis-D states resulting from excessive treatment of hypoparathyroidism, self-administration of vitamins, and the presence of a granulomatous disease, such as sarcoidosis. Any other cause of hypercalcemia (increased calcium in the blood), particularly when associated with hypercalciuria (increased calcium in the urine). Causes include milk-alkali syndrome (due to excess ingestion of antacids), hyperparathyroidism, and malignant disease. Idiopathic hypercalciuria,a common metabolic disease, is also a known cause. Nephrocalcinosis and renal failure are increasingly being recognized as common complications of phosphate supplementation, particularly in the elderly.Phosphate supplements may contribute to renal calcifications in children with hypophosphatemic rickets. Medullary sponge kidney Rapidly progressive osteoporosis due to immobilization, menopause, aging, or steroids.

<s>[INST] What are the treatments for Nephrocalcinosis ? [/INST] How might nephrocalcinosis be treated? Treatment of nephrocalcinosis includes treating the underlying condition causing nephrocalcinosis, if it is known. The goal of treatment is to reduce symptoms and prevent more calcium from being deposited in the kidneys. Measures are usually taken to reduce abnormal levels of calcium, phosphate, and oxalate in the blood. Medications that cause calcium loss are typically stopped. Treatment of hypercalcemia (increased calcium levels in the blood) and hypercalcemic nephropathy typically includes adequate hydration by isotonic sodium chloride (normal saline) solution to reverse hypercalcemia and protect the kidneys. Treatment of macroscopic nephrocalcinosis (calcium deposition that is visible without magnification) may include thiazide diuretics and dietary salt restriction; potassium and magnesium supplementation; and citrate supplementation in idiopathic hypercalciuria (of unknown cause) and in distal renal tubular acidosis. Lessening of nephrocalcinosis may occur over time, but in many cases, such as when it results from primary hyperoxaluria or distal renal tubular acidosis, nephrocalcinosis is largely irreversible. Therefore, early detection and treatment are important. Individuals interested in learning about treatment options for themselves should speak with their health care provider or a nephrologist. </s></s>

<s>[INST] What causes Klinefelter syndrome ? [/INST] What causes Klinefelter syndrome? Klinefelter syndrome 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. For example, an egg or sperm cell may gain one or more extra copies of the X chromosome as a result of nondisjunction. If one of these atypical reproductive cells contributes to the genetic makeup of a child, the child will have one or more extra X chromosomes in each of the body's cells. Most often, Klinefelter syndrome is caused by a single extra copy of the X chromosome, resulting in a total of 47 chromosomes per cell. Males normally have one X chromosome and one Y chromosome in each cell (46, XY), while females have two X chromosomes (46, XX). People with Klinefelter syndrome usually have two X chromosomes and one Y chromosome (47, XXY). Some people with Klinefelter syndrome have the extra X chromosome in only some of their cells; these people are said to have mosaic Klinefelter syndrome. It is estimated that about half of the time, the cell division error occurs during development of the sperm, while the remainder are due to errors in egg development. Women who have pregnancies after age 35 have a slightly increased chance of having offspring with this syndrome. The features of Klinefelter syndrome are due to the extra copies of genes on the extra X chromosome, which can alter male sexual development. </s></s>

Because symptoms of Klinefelter syndrome (KS) can sometimes be very mild, many people are never diagnosed or treated. When a diagnosis is made, treatment is based on the signs and symptoms present in each person. This may include: Educational interventions - As children, many people with Klinefelter syndrome qualify for special services to help them in school. Teachers can also help by using certain methods in the classroom, such as breaking bigger tasks into small steps. Therapeutic options - A variety of therapists, such as physical, speech, occupational, behavioral, mental health, and family therapists can often help reduce or eliminate some of the symptoms of Klinefelter syndrome such as poor muscle tone; speech and language problems; or low self-confidence. Medical management - About half of people with KS have low testosterone levels, which may be raised by taking supplemental testosterone. Having a more normal testosterone level can help affected people develop bigger muscles, a deeper voice, and facial and body hair. Many healthcare providers recommend testosterone therapy when a boy reaches puberty. However, not all males with KS benefit from testosterone therapy. Some affected people may opt to have breast removal or reduction surgery.

[/INST] Periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis (PFAPA) is a periodic disease, which is a heterogeneous group of disorders characterized by short episodes of illness that regularly recur for several years alternated with healthy periods. PFAPA is characterized by high fevers lasting three to six days and recurring every 21 to 28 days, accompanied by some or all of the signs noted in its name, namely mouth sores (aphthous stomatitis), sore throat (pharyngitis), and enlarged lymph nodes (cervical adenitis). The syndrome usually occurs in children younger than five years; although it has been reported in children up to 13 years. The syndrome is sporadic and non-hereditary. The course of PFAPA can be persistent for years before spontaneous, full resolution. </s></s>

<s>[INST] What is (are) Asperger syndrome ? [/INST] Asperger syndrome (AS) is an autism spectrum disorder, a type of neurological condition characterized by impaired language and communication skills, and repetitive or restrictive thought and behavior patterns. Unlike many people with autism, those with AS retain their early language skills. Features of AS include an obsessive interest in a particular object or topic; high vocabulary; formal speech patterns; repetitive routines or habits; inappropriate social and emotional behavior; impaired non-verbal communication; and uncoordinated motor skills. AS is likely caused by a combination of genetic and environmental influences. While autism spectrum disorders including AS sometimes run in families, no specific inheritance pattern has been recognized. </s></s>

<s>[INST] What is (are) Beta ketothiolase deficiency ? [/INST] Beta-ketothiolase deficiency is an inherited disorder in which the body cannot effectively process a protein building block (amino acid) called isoleucine. This condition also impairs the body's ability to process ketones, which are molecules produced during the breakdown of fats. Signs and symptoms typically appear between the ages of 6 months and 24 months. Affected children experience episodes of vomiting, dehydration, difficulty breathing, extreme tiredness (lethargy), and occasionally seizures. These episodes, which are called ketoacidotic attacks, sometimes lead to coma. Ketoacidotic attacks are frequently triggered by infections, periods without food (fasting), or increased intake of protein-rich foods. This condition is inherited in an autosomal recessive fashion and is caused by mutations in the ACAT1 gene. </s></s>

<s>[INST] What is (are) Stargardt disease ? [/INST] Stargardt disease is a genetic eye disorder that causes progressive vision loss. It affects the macula, an area of the retina responsible for sharp, central vision. Vision loss is due to abnormal accumulation of a fatty yellow pigment (lipofuscin) in the cells within the macula. People with Stargardt disease also have problems with night vision, and some have problems with color vision. The signs and symptoms of Stargardt disease typically appear in late childhood to early adulthood and worsen over time. It is most commonly caused by mutations in the ABCA4 gene and inherited in an autosomal recessive manner. Rarely it may be caused by mutations in other genes and inherited in an autosomal dominant manner. There is currently no treatment, but various services and devices can help affected people carry out daily activities and maintain their independence. </s></s>

<s>[INST] Is Stargardt disease inherited ? [/INST] How is Stargardt disease inherited? Stargardt disease is most commonly inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. Affected people inherit one mutated copy of the gene from each parent, who is referred to as a carrier. Carriers of an autosomal recessive condition typically do not have any signs or symptoms (they are unaffected). When 2 carriers of an autosomal recessive condition have children, each child has a: 25% (1 in 4) chance to be affected 50% (1 in 2) chance to be an unaffected carrier like each parent 25% chance to be unaffected and not be a carrier A person with autosomal recessive Stargardt disease will always pass one mutated copy of the gene to each of his/her children. In other words, each of his/her children will at least be a carrier. A child of an affected person can be affected if the other parent is also affected or is a carrier. In rare cases, Stargardt disease may be inherited in an autosomal dominant manner. This means that having a mutation in only one copy of the responsible gene in each cell is enough to cause features of the condition. An affected person typically inherits the mutated gene from an affected parent. When a person with a mutation that causes an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit that mutation. </s></s>

The Genetic Testing Registry (GTR) provides information about the genetic tests available for Stargardt disease. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about genetic testing for this condition should speak with their ophthalmologist or a genetics professional. </s></s>

<s>[INST] What are the treatments for Stargardt disease ? [/INST] How might Stargardt disease be treated? At present there is no cure for Stargardt disease, and there is very little that can be done to slow its progression. Wearing sunglasses to protect the eyes from UVa, UVb and bright light may be of some benefit. Animal studies have shown that taking excessive amounts of vitamin A and beta carotene could promote the additional accumulation of lipofuscin, as well as a toxic vitamin A derivative called A2E; it is typically recommended that these be avoided by individuals with Stargardt disease. There are possible treatments for Stargardt disease that are being tested, including a gene therapy treatment, which has been given orphan drug status by the European Medicines Agency (EMEA, similar to the FDA).

Features of Noonan syndrome may include a distinctive facial appearance, short stature, a broad or webbed neck, congenital heart defects, bleeding problems, skeletal malformations, and developmental delay. Noonan syndrome may be caused by mutations in any one of several genes including the PTPN11, KRAS, RAF1, SOS1, NRAS and BRAF genes. It is sometimes referred to as a specific subtype based on the responsible gene in an affected person. Noonan syndrome is typically inherited in an autosomal dominant manner but many cases are due to a new mutation and are not inherited from an affected parent. </s></s>

In some cases, the genes responsible have not yet been found. </s></s>

<s>[INST] How to diagnose Primary Familial Brain Calcification ? [/INST] How is primary familial brain calcification (PFBC) diagnosed? The diagnosis of PFBC relies upon: 1) visualization of bilateral (on both sides) calcification of the basal ganglia on neuroimaging, 2) presence of progressive neurological dysfunction, 3) absence of a metabolic, infectious, toxic, or traumatic cause, and 4) a family history consistent with autosomal dominant inheritance (a person must inherit one copy of the altered gene from one parent to have the condition). Molecular genetic testing can help confirm the diagnosis. Is there genetic testing for primary familial brain calcification (PFBC) even though not all of the causitive genes are known? Genetic testing may help to confirm the diagnosis. For individuals in who a diagnosis of PFBC is being considered, other causes of brain calcification should be eliminated prior to pursuing genetic testing, particularly in simplex cases. Testing that might be done includes biochemical analysis of blood and urine, as well s analysis of cerebrospinal fluid. If no other primary cause for brain calcification is detected or if the family history is suggestive of autosomal dominant inheritance, molecular genetic testing should be considered. Sequencing of SLC20A2 should be pursued first. If no mutation is identified, deletion/duplication analysis of SLC20A2 may be considered. If no identifiable mutation or deletion in SLC20A2 is found, sequence analysis of PDGFRB and PDGFB may be considered. </s></s>

<s>[INST] What is (are) Urea cycle disorders ? [/INST] A urea cycle disorder is a genetic disorder that results in a deficiency of one of the six enzymes in the urea cycle. These enzymes are responsible for removing ammonia from the blood stream. The urea cycle involves a series of biochemical steps in which nitrogen, a waste product of protein metabolism, is changed to a compound called urea and removed from the blood. Normally, the urea is removed from the body through the urine. In urea cycle disorders, nitrogen builds up in the blood in the form of ammonia, a highly toxic substance, resulting in hyperammonemia (elevated blood ammonia). Ammonia then reaches the brain through the blood, where it can cause irreversible brain damage, coma and/or death. The onset and severity of urea cycle disorders is highly variable. The severity correlates with the amount of urea cycle enzyme function. </s></s>

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. </s></s>

<s>[INST] What are the symptoms of Necrotizing fasciitis ? [/INST] 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. </s></s>

<s>[INST] What causes Necrotizing fasciitis ? [/INST] 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. </s></s>

<s>[INST] What are the treatments for Necrotizing fasciitis ? [/INST] 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. </s></s>

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. </s></s>
