[3] Other risk factors include certain antiseizure medications, obesity, and poorly managed diabetes. ", "Spinal radiographic findings and nonspecific low back pain. Kohl T, Schürg R, Maxeiner H, Tchatcheva K, Degenhardt J, Stressig R, Axt-Fliedner R, Gembruch U. [2] Problems associated with this form include poor ability to walk, impaired bladder or bowel control, accumulation of fluid in the brain (hydrocephalus), a tethered spinal cord and latex allergy. Problems associated with lipomyelomeningocoele are caused by the spinal cord and nerves being trapped within the fatty lump, and the lump putting pressure on the spinal nerves. [21][22][23], However, other studies suggest spina bifida occulta is not always harmless. [43] In addition to brain abnormalities directly related to various academic skills, achievement is likely affected by impaired attentional control and executive functioning. In this form of spina bifida, there is only a small defect or gap in the small bones (vertebrae) that make up the spine, which occurs in about 12% of the population. Sometimes, the nerves are entangled in the fatty lump, and it is not possible to free all the nerves or remove all the fat. Four cases were performed before stopping the procedure - two of the four fetuses died. This is the most common and serious type of spina bifida. In occulta, the outer part of some of the vertebrae is not completely closed. [citation needed], A meningocele may also form through dehiscences in the base of the skull. [98][99][100][101][102][103][104][105][excessive citations], Since then more data has emerged. [65] To the mother, this includes scarring of the uterus. [60] The U.S. Food and Drug Administration, Public Health Agency of Canada[61] and UK recommended amount of folic acid for women of childbearing age and women planning to become pregnant is at least 0.4 mg/day of folic acid from at least three months before conception, and continued for the first 12 weeks of pregnancy. [39], Individuals with spina bifida, especially those with shunted hydrocephalus, often have attention problems. [82], Fetal surgery after 25 weeks has not shown benefit in subsequent studies. A transition plan and aid in identifying adult healthcare professionals are also helpful to include in the transition process. T. Lissauer, G. Clayden. Often people only become aware that they have the condition after having a back x-ray or scan for an unrelated problem or for back pain. [34] In fact, the cerebellum also tends to be smaller in individuals with spina bifida, especially for those with higher lesion levels. [49] Individuals with spina bifida may have difficulty with writing due to deficits in fine motor control and working memory. [17] In open spina bifida, the appearance of the skull bones and cerebellum - part of the back of the brain - show distinct signs to lead the sonographer to look for tiny changes in the spine. Spina bifida occulta is the mildest form of spina bifida and is defined as an incomplete fusion of the posterior arch of the vertebrae. Spina Bifida Occulta usually does not cause harm and has no visible signs. Spina Bifida Cystica with Meningocele. [91], The observations in mothers and their fetuses that were operated over the past two and a half years by the matured minimally invasive approach showed the following results: Compared to the open fetal surgery technique, fetoscopic repair of myelomeningocele results in far less surgical trauma to the mother, as large incisions of her abdomen and uterus are not required. In this type, the involved area is represented by a flattened, plate-like mass of nervous tissue with no overlying membrane. [27] In individuals with myelomeningocele, the unfused portion of the spinal column allows the spinal cord to protrude through an opening. By using Shine, you agree to our Privacy Policy. The spine is a column of vertebral bodies (bones) with discs of fibrous tissue between them. In addition, a shunt may be surgically installed to provide a continuous drain for the excess cerebrospinal fluid produced in the brain, as happens with hydrocephalus. Types of Spina Bifida. RESULTS: Eighteen infants diagnosed with spinal NTDs (prevalence 1.6/10,000) included 13 with spina bifida cystica and 5 with spina bifida occulta. Open spina bifida (spina bifida cystica - cyst-like) The visible signs are a sac or cyst, rather like a large blister on the back. There may be visible signs on the back such as a lump, a haemangioma or naevus (strawberry birthmark), a deep dimple or sinus (hole) above the cleft of the buttocks, or a tuft of hair (similar to head hair, rather than downy back hair). This approach has been evaluated by independent authors of a controlled study which showed some benefit in survivors,[90] but others are more skeptical. [6] Urinary catheterization may also be needed.[6]. [106][107] These papers suggested that the risk to the mother is small. These may be classified by their localisation to occipital, frontoethmoidal, or nasal. Spina Bifida Occulta (SBO) usually does not cause harm, and has no visible signs. [58] Globally, fortified wheat flour is credited with preventing 50 thousand neural tube birth defects like spina bifida a year, but 230,000 could be prevented every year through this strategy. This prevents an estimated 600 to 700 incidents of spina bifida a year in the U.S. and saves $400 - $600 million in healthcare expenses. ", "How do health care providers diagnose spina bifida? The second is via fetoscopy. In the majority of cases, though, spina bifida is an isolated malformation. [9] Occulta has no or only mild signs, which may include a hairy patch, dimple, dark spot or swelling on the back at the site of the gap in the spine. In children, this can be a normal part of development, with some of the lowest vertebrae not closing completely until the teenage years. White matter tracts between frontal regions have also been found to be impaired. Bladder and bowel control problems, including incontinence, 1980 – Fetal surgical techniques using animal models were first developed at the, 1994 – A surgical model that simulates the human disease is the fetal lamb model of myelomeningocele (MMC) introduced by Meuli and Adzick in 1994. [10], Toxins and conditions associated with MMC formation include: calcium-channel blockers, carbamazepine, cytochalasins, hyperthermia, and valproic acid. [citation needed], Incomplete posterior fusion is not a true spina bifida, and is very rarely of neurological significance. [92][93][94] Women are discharged home from hospital one week after the procedure. Development of the spinal cord may be affected, but impairment is usually less severe than myelomeningocele. Spina Bifida Occulta. People find out they have it after having an X … [12], Spina bifida with myelocele is the most severe form of myelomeningocele. [16], Occulta is Latin for "hidden". Provided the spinal cord or nerves are not affected, there should be no impact on walking or bladder and bowel function. In one study, 60% of children with spina bifida were diagnosed with a learning disability. In lipomyelomeningocoele, the brain and skull will usually look normal so the changes to the spine may not be detected. It is usually not detected at the antenatal mid-term ultrasound scan. [15] The term spina bifida is Latin for "split spine". [citation needed], Many people with this type of spina bifida do not even know they have it, as the condition is asymptomatic in most cases. [citation needed]. Sources of folic acid include whole grains, fortified breakfast cereals, dried beans, leaf vegetables and fruits. spina bifida cystica: [ spi´nah ] ( L. ) spine (def. Around 90% of people with lipomyelomeningocoele have markers on their back such as fatty lumps, birthmarks or deep dimples. At one year of age, 40 percent of the children in the prenatal surgery group had received a shunt, compared to 83 percent of the children in the postnatal group. As a result, there is nearly always some resulting paralysis and loss of sensation. A systematic review of observational studies", "Anomalous development of brain structure and function in spina bifida myelomeningocele", "Protect Yourself From Latex Allergies: Plant Biologists And Immunochemists Develop Hypoallergenic Alternative To Latex", "Chiari Malformation Fact Sheet: National Institute of Neurological Disorders and Stroke (NINDS)", "Age-related changes in executive function among children with spina bifida/hydrocephalus based on parent behavior ratings", "Arithmetic processing in children with spina bifida: Calculation accuracy, strategy use, and fact retrieval fluency", "Mathematical developmental development in spina bifida", "it is more often due to direct toxicity of the alcohol on the marrow. [10], Most cases of spina bifida can be prevented if the mother gets enough folate before and during pregnancy. The exposure of these nerves and tissues make the baby more prone to life-threatening infections such as meningitis. With it, there is a small gap in the spine, but no opening or sac on the back. Kohl T, Kawecki A, Degenhardt J, Axt-Fliedner R, Neubauer B. Children with spina bifida are more likely than their peers without spina bifida to be dyscalculic. Spina bifida is a birth defect that occurs when the spine and spinal cord don't form properly. Spina bifida was described in the medieval literature and was recognized even earlier. After stopping the drinking of alcohol, a time period of months is needed to rejuvenate bone marrow and recover from the macrocytosis. Ultrasound view of the fetal spine at 21 weeks of pregnancy. [45] Mathematics difficulties may be directly related to the thinning of the parietal lobes (regions implicated in mathematical functioning) and indirectly associated with deformities of the cerebellum and midbrain that affect other functions involved in mathematical skills. [24][25] "Early neurological findings in 20 infants after minimally-invasive fetoscopic surgery for spina bifida at the University of Giessen 2010–2011. spina bifida cystica in particular have assumed greater importance in recent years. [15] It is most common in the Celtic people (12.5 per 10,000 live births), and it is rare in Asians and people of African descent. [31], Cortex abnormalities may also be present. Problems can also develop if the person gains weight – because the lump is made of fat cells, they become larger with weight gain like other fat cells in the body. Spina bifida occulta, a confusing term, is defined as a defect in the posterior bony components of the vertebral column without involvement of the cord or meninges. Treatment usually involves surgery to remove the bone and to free up the spinal cord (. [citation needed], There is neither a single cause of spina bifida nor any known way to prevent it entirely. The first is open fetal surgery, where the uterus is opened and the spina bifida repair performed. [72] As part of the transition process, it is beneficial to begin discussions at an early age about educational and vocational goals, independent living, and community involvement. The adolescent's multidisciplinary treatment team may aid in the process by preparing comprehensive, up-to-date documents detailing the adolescent's medical care, including information about medications, surgery, therapies, and recommendations. Usually, spina bifida occulta causes no health problems. Spina bifida is among the phenotypes of the larger condition known as neural tube defects (NTDs). Ultrasound screening for spina bifida is partly responsible for the decline in new cases, because many pregnancies are terminated out of fear that a newborn might have a poor future quality of life. Either the split in the spine is bigger, or may involve two or more vertebrae. [citation needed], Myelomeningocele (MMC), also known as meningomyelocele, is the type of spina bifida that often results in the most severe complications and affects the meninges and nerves. It can affect as many as 1 out of every 800 babies. [40] Further, children with spina bifida may have poor cognitive flexibility. Spina bifida does not follow direct patterns of heredity as do muscular dystrophy or haemophilia. Among females, this could be mistaken for dysmenorrhea. The three most common types of spina bifida are:Myelomeningocele (sounds like: my-low-ma-nin-jo-seal; hear how “myelomeningocele” soundsexternal icon)When people talk about spina bifida, most often they are referring to myelomeningocele. This defect is indicated more often by a skin lesion such as a hairy patch, dermal sinus tract, dimple, hemangioma, or lipoma .The occurrence of spina bifida occulta in sacral region spreading from S1 to S5 has been termed as sacral spina bifida occulta (SSBO). For most people affected, SBO will have no impact on their lives. Related conditions [74], In the United States, rates are higher on the East Coast than on the West Coast, and higher in white people (one case per 1000 live births) than in black people (0.1–0.4 case per 1000 live births). Reversal of the hindbrain herniation component of the Chiari II malformation, Reduced need for ventricular shunting (a procedure in which a thin tube is introduced into the brain's ventricles to drain fluid and relieve hydrocephalus), Reduced incidence or severity of potentially devastating, This page was last edited on 4 January 2021, at 10:04. Degenhardt J, Schürg R, Kawecki A, Pawlik M, Enzensberger C, Stressig R, Axt-Fliedner R, Kohl T. "Maternal outcome after minimally-invasive fetoscopic surgery for spina bifida. Nerves to and from the spinal cord emerging below the damaged region may not pass messages to the brain. It is often called “hidden Spina Bifida” because about 15 percent of healthy people have it and do not know it. These fat cells prevent the spinal bones closing completely, leaving the ‘spina bifida’ gap. Physical signs of spina bifida may include: 68% of children with spina bifida have an allergy to latex,[32] ranging from mild to life-threatening. Meningocele is the least common form of spina bifida. Shine uses browser cookies to give you the best possible experience. It may be associated with a fatty lump embedded in the spinal column (lipomyelomeningocoele), or a piece of bone which divides the spinal cord (diastematomyelia). German Society for Prenatal Medicine and Obstetrics, International Society of Obstetrics and Gynecology, "Are there disorders or conditions associated with spina bifida? [6] A shunt may be needed in those with hydrocephalus, and a tethered spinal cord may be surgically repaired. Spina bifida is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [89], In contrast to the open fetal operative approach performed in the MOMS trial, a minimally invasive fetoscopic approach (akin to 'keyhole' surgery) has been developed. Fat cells may also be present at the bottom of the spinal cord (fatty filum terminale). In the axial scan the characteristic lemon sign and banana sign are seen. [14] Part of this difference is believed to be due to race, with Caucasians at higher risk, and part due to environmental factors. It is also necessary to have intact nerve pathways to the brain for complete control and sensation. [26], A posterior meningocele (/mɪˈnɪŋɡəˌsiːl/) or meningeal cyst (/mɪˈnɪndʒiəl/) is the least common form of spina bifida. Occulta is often called hidden spina bifida, as the spinal cord and the nerves are usually normal and there is no opening on the back. Like other forms of spina bifida, it develops during early pregnancy. It also differs from open spina bifida as it is usually not associated with brain development problems such as Chiari II, so learning and general development should also follow typical patterns. [citation needed]. 2. [75][76] Since then, the rate has fallen dramatically with 0.15 per 1000 live births reported in 1998,[53] though this decline is partially accounted for because some fetuses are aborted when tests show signs of spina bifida (see Pregnancy screening above). spina bi´fida a developmental anomaly characterized by defective closure of the bony encasement of the spinal cord; the spinal cord and meninges may or may not protrude through the defect (see spina bifida cystica and spina bifida occulta). The prevalence varies across time, by region and by both race and ethnicity. spina [spi´nah] (L.) spine (def. 877990Privacy Policy. There are three types of spina bifida: myelomeningocele, meningocele, and spina bifida occulta. [3] After having one child with the condition, or if one of the parents has the condition, there is a 4% chance that the next child will also be affected. Treatment for lipomyelomeningocoele, if needed, is usually by surgery to release the nerves from within the fatty lump, which will be done by a Neurosurgeon. Healthcare professionals working with adults may also be less knowledgeable about spina bifida because it is considered a childhood chronic health condition. Need more help? The main risk appears to be preterm labour, on average at about 33 weeks. Shine uses browser cookies to give you the best possible experience. Girls are more prone to being born with spina bifida. Spina bifida in its strictest sense means defective fusion of the vertebral posterior elements, leading to a bifid osseous configuration of the spine 16. However, dietary supplementation with folic acid has been shown to be helpful in reducing the incidence of spina bifida. However, most commonly it is used as a synonym or subset of spinal dysraphism. [48], Spina bifida is believed to be caused by a combination of genetic and environmental factors. Some forms are known to occur with primary conditions that cause raised central nervous system pressure, raising the possibility of a dual pathogenesis.[52]. The neural tube is the embryonic structure that eventually develops into the baby's brain and spinal cord and the tissues that enclose them.Normally, the neural tube forms early in pregnancy, and it closes by the 28th day after conception. [51], Spina bifida occurs when local regions of the neural tube fail to fuse or there is failure in formation of the vertebral neural arches. [84], Management of myelomeningocele study (MOMS) was a phase III clinical trial designed to compare two approaches to the treatment of spina bifida: surgery before birth and surgery after birth. Supplementation of the mother's diet with folate can reduce the incidence of neural tube defects by about 70%, and can also decrease the severity of these defects when they occur. Medical imaging can confirm the diagnosis after birth. This happens during the first month of gestation, when a neural tube is developed. [62] This stops the spinal cord from moving freely inside the spinal bones, and with growth the nerves become stretched and damaged; this is what is meant by ‘tethered cord’. ", "Neural tube defects: prevalence, etiology and prevention", "Spina Bifida Fact Sheet | National Institute of Neurological Disorders and Stroke", "Impact of folic acid fortification of flour on neural tube defects: a systematic review", "Are There Different Types Of Spina Bifida? As a result, there is usually some degree of paralysis and loss of sensation below the level of the spinal cord defect. These are: The visible signs are a sac or cyst, rather like a large blister on the back. [8] Rates of other types of spina bifida vary significantly by country from 0.1 to 5 per 1000 births. Neural arch formation occurs in the first month of embryonic development (often before the mother knows she is pregnant). [citation needed], In 2012, these results of the fetoscopic approach were presented at various national and international meetings, among them at the 1st European Symposium “Fetal Surgery for Spina bifida“ in April 2012 in Giessen, at the 15th Congress of the German Society for Prenatal Medicine and Obstetrics in May 2012 in Bonn,[95] at the World Congress of the Fetal Medicine Foundation in June 2012[96] and at the World Congress of the International Society of Obstetrics and Gynecology (ISUOG) in Copenhagen in September 2012,[97] and published in abstract form. Spina bifida occulta may leave those with the condition susceptible to symptoms caused by their spinal column being left exposed. [36] Children with spina bifida may perform well in elementary school, but begin to struggle as academic demands increase. [5] Before birth, if a blood test or amniocentesis finds a high level of alpha-fetoprotein (AFP), there is a higher risk of spina bifida. Indeed, the association of foot deformities with sacral hypertrichosis may be the origin of the mythological figure of the satyr . Symptoms may include ambulatory problems, loss of sensation, deformities of the hips, knees or feet, and loss of muscle tone. Spina bifida remains a challenging neurosurgical entity to manage despite both an increased awareness of the disease as well as a decreased incidence due to folic acid supplementation. As lipomyelomeningocoele is skin covered, no ‘back closure’ surgery is needed at birth. [7] In the United States it affected about 0.7 per 1000 births,[4] and in India about 1.9 per 1000 births. Genetic counseling and further genetic testing, such as amniocentesis, may be offered during the pregnancy, as some neural tube defects are associated with genetic disorders such as trisomy 18. Around 5% of people with lipomyelomeningocoele have aqueduct stenosis (blockage cause by narrowing) which can lead to hydrocephalus. Spina bifida cystica can then be broken down into meningocele and myelomeningocele. It is the most common central nervous system malformation compatible with life and the second leading cause of birth defects after congenital heart defects. Poor ability to walk, problems with bladder or bowel control, 15% (occulta), 0.1–5 per 1000 births (others). [31], The corpus callosum is abnormally developed in 70–90% of individuals with spina bifida myelomeningocele; this affects the communication processes between the left and right brain hemispheres. [12] On average, in developed countries, including the United States, it occurs in about 0.4 per 1,000 births. Bladder and bowel problems occur in most people with myelomeningocele, as the nerves come from the very bottom of the spinal cord, and are always below the lesion. [5][1] Meningocele typically causes mild problems, with a sac of fluid present at the gap in the spine. 1998 – N. Scott Adzick and team at The Children's Hospital of Philadelphia performed open fetal surgery for spina bifida in an early gestation fetus (22-week gestation fetus) with a successful outcome. Many times, Spina Bifida Occulta is not discovered until late childhood or adulthood.

There are two types: spina bifida occulta and spina bifida cystica. DefinitionIt is type of spina bifida cystica characterized by the herniation of spinal cord contents and meninges through an abnormal defect in the back bone [1].. It is a rather common condition, occurring in about 10-20% of people. It is very important that all children with conditions which affect the nerves to their bladders have their bladder function checked regularly by a Urologist. There are a number of conditions that share features with, or are otherwise closely linked to spina bifida. ", "In utero repair of myelomeningocele: experimental pathophysiology, initial clinical experience, and outcomes", "The Fetal Medicine Foundation / FMF World Congress", "Percutaneous minimally invasive fetoscopic surgery for spina bifida aperta. ", "How many people are affected by or at risk for spina bifida? There are two types: spina bifida occulta and spina bifida cystica. During pregnancy, all the fetuses in the trial had hindbrain herniation. Depending on the findings, a referral to a neurosurgeon might be appropriate. The spinal cord can become tethered because of the extra bone or tissue. Constipation or frequent soiling may be experienced too, and several options for good management are available, such as washout systems. Research has shown the lack of folic acid (folate) is a contributing factor in the pathogenesis of neural tube defects, including spina bifida. [6] Devices to help with movement such as crutches or wheelchairs may be useful. Spina bifida occulta (SBO) is a type of spinal dysraphism or ‘closed’, skin-covered form of spina bifida. Spina bifida occulta results from incomplete closure of the neural tube around the twentieth day of embryonic development . [3] Adding folic acid to flour has been found to be effective for most women. Further, higher numbers of shunt revisions are associated with poorer mathematics abilities. Spina= Latin: “spine” Bifida= Latin:“split”Occulta = Latin: “hidden.” (Unlike in “open” spina bifida, the defect in spina bifida occulta is not visible. [44] Individuals with spina bifida have demonstrated stable difficulties with arithmetic accuracy and speed, mathematical problem-solving, and general use and understanding of numbers in everyday life. [16] Spina bifida cystica can then be broken down into meningocele and myelomeningocele. The second type of spina bifida is called meningocele or spina bifida cystica with meningocele. However, at age 12 months, one-third (36 percent) of the infants in the prenatal surgery group no longer had any evidence of hindbrain herniation, compared to only 4 percent in the postnatal surgery group. [59], Folate fortification of enriched grain products has been mandatory in the United States since 1998. In one case, a man born with spina bifida was awarded a $2-million settlement after court found his mother's OBGYN negligent for not performing these tests. Immigrants from Ireland have a higher incidence of spina bifida than do natives. [12] On average in developed countries it occurs in about 0.4 per 1000 births. [3] The meningeal membranes that cover the spinal cord also protrude through the opening, forming a sac enclosing the spinal elements, such as meninges, cerebrospinal fluid, and parts of the spinal cord and nerve roots. To be specific, the study found that prenatal repair resulted in: [88] The MMC-like defect was surgically created at 75 days of gestation (term 145 to 150 days) by a lumbo-sacral. Myelomeningocele occurs in the third week of embryonic development, during neural tube pore closure. Around half of people with diastematomyelia have their spinal cord divided by an extra piece of bone or band of fibrous tissue in the spinal canal. [35] Further, white matter tracts connecting posterior brain regions with anterior regions appear less organized. 1). The Giessen experience 2010–2012. [5] Spina bifida is a type of neural tube defect related to but distinct from other types such as anencephaly and encephalocele. Myelomeningocele is the most serious type of spina bifida. It is sometimes called “hidden” spina bifida. A common symptom of spina bifida occulta is persistent lower back pain 1.According to the Spina Bifida Association, a regular routine of stretching exercises can relieve that pain and keep your spine limber 1 2.Perform hamstring stretches, lower back and hip flexor stretches as well as heel stretches daily to prevent the discomfort. Open spina bifida can usually be detected during pregnancy by fetal ultrasound. [ 1 ] [75][76] Highest rates of the defect in the USA can be found in Hispanic youth.[77]. The bones around the spinal cord fail to develop normally, but the nerves don't generally have any damage. It occurs in at least 5% of the population but most often is asymptomatic. [65], Broadly, there are two forms of prenatal treatment. [1] The most common location is the lower back, but in rare cases it may be in the middle back or neck. [1] Myelomeningocele, also known as open spina bifida, is the most severe form. spina bi´fida a developmental anomaly characterized by defective closure of the bony encasement of the spinal cord; the spinal cord and meninges may or may not protrude through the defect (see spina bifida cystica and spina bifida occulta ).
