Human spina bifida, like other human diseases, such as cancer, hypertension and atherosclerosis (coronary artery disease), likely results from the interaction of multiple genes and environmental factors. [53] However, if something interferes and the tube fails to close properly, a neural tube defect will occur. 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. [92][93][94] Women are discharged home from hospital one week after the procedure. [ 1 ] [12] On average in developed countries it occurs in about 0.4 per 1000 births. However, for some people, there are associated conditions which can have a significant impact on their lives and abilities. Around 5% of people with lipomyelomeningocoele have aqueduct stenosis (blockage cause by narrowing) which can lead to hydrocephalus. [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. Spina bifida cystica causes a problem when cord tissue extends into the meningocele, in which case the cyst is called a myelomeningocele. There may be a hairy patch, dimple, or birthmark over the area of the defect. Sometimes, the nerves are entangled in the fatty lump, and it is not possible to free all the nerves or remove all the fat.

It can affect as many as 1 out of every 800 babies. It is sometimes called “closed” spina bifida. 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. Other times, there may be no abnormalities in the area. [citation needed], There is neither a single cause of spina bifida nor any known way to prevent it entirely. The bones around the spinal cord fail to develop normally, but the nerves don't generally have any damage. If you suspect that you may have spina bifida occulta and are experiencing a few of the problems described above, ask your GP to arrange to investigate. 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. The effects and complications of spina bifida occulta are caused by nerves and spinal tissue being trapped, caught up on abnormal pieces of bone, or tangled in fatty lumps, which prevent the spine moving freely inside the spinal column (see our information on tethered cord). [6] A shunt may be needed in those with hydrocephalus, and a tethered spinal cord may be surgically repaired. The most common approach to avoid developing an allergy is to avoid contact with latex-containing products such as examination gloves and condoms and catheters that do not specify they are latex-free, and many other products, such as some commonly used by dentists. Spina bifida is present from birth and can take several forms. [17] In this form, the sac contains meninges (tissues which cover the brain and spinal cord) and CSF, but no spinal tissue. Around 90% of people with lipomyelomeningocoele have markers on their back such as fatty lumps, birthmarks or deep dimples. Healthcare professionals working with adults may also be less knowledgeable about spina bifida because it is considered a childhood chronic health condition. In normal circumstances, the closure of the neural tube occurs around the 23rd (rostral closure) and 27th (caudal closure) day after fertilization. [7][4][13] In India, it affects about 1.9 per 1,000 births. Myelomeningocele is the most serious type of spina bifida. [4] Not having enough folate (vitamin B9) in the diet before and during pregnancy also plays a significant role. Provided the spinal cord or nerves are not affected, there should be no impact on walking or bladder and bowel function. Many times, Spina Bifida Occulta is not discovered until late childhood or adulthood. Standard treatment is surgery after delivery. They are treated surgically. Treatment usually involves surgery to remove the bone and to free up the spinal cord (. [53], Three-dimensional ultrasound image of the fetal spine at 21 weeks of pregnancy. 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. [48], Spina bifida is believed to be caused by a combination of genetic and environmental factors. Shunts most commonly drain into the abdomen or chest wall. 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. [85][86], The trial concluded that the outcomes after prenatal spina bifida treatment are improved to the degree that the benefits of the surgery outweigh the maternal risks. The exact cause is still uncertain, but it is thought that a layer of cells (which will develop into the skin) detaches from the neural tissue too early, allowing fat cells to become attached to the spinal cord, where they grow to form a lump. [39], Individuals with spina bifida, especially those with shunted hydrocephalus, often have attention problems. Lipomyelomeningocoele often affects the bladder and bowel, so difficulty with potty training, frequency or urgency of passing urine, a poor, ‘dribbling’ stream of urine in boys, or urine infections may occur. [34] In fact, the cerebellum also tends to be smaller in individuals with spina bifida, especially for those with higher lesion levels. [2], Spina bifida is believed to be due to a combination of genetic and environmental factors. It occurs when the bones of the spine (vertebrae) do not close completely. The first is open fetal surgery, where the uterus is opened and the spina bifida repair performed. ", "How do health care providers diagnose spina bifida? 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. Here the cyst not only contains tissue and cerebrospinal fluid (CSF) but also nerves and part of the spinal cord.

Increased levels of maternal serum alpha-fetoprotein (MSAFP) should be followed up by two tests – an ultrasound of the fetal spine and amniocentesis of the mother's amniotic fluid (to test for alpha-fetoprotein and acetylcholinesterase). Illustrated Textbook of Paediatrics (Second Edition). It is sometimes called “hidden” spina bifida. 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. [24][25] RESULTS: Eighteen infants diagnosed with spinal NTDs (prevalence 1.6/10,000) included 13 with spina bifida cystica and 5 with spina bifida occulta. This is the mildest form of spina bifida. In one study, 60% of children with spina bifida were diagnosed with a learning disability. Open spina bifida (spina bifida cystica - cyst-like) The visible signs are a sac or cyst, rather like a large blister on the back. [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. [54][55][56] It is unknown how or why folic acid has this effect. Kohl T, Kawecki A, Degenhardt J, Axt-Fliedner R. "Preoperative sonoanatomic examination of fetal spina bifida permits prediction of surgical complexity during subsequent minimally-invasive fetoscopic closure. The spinal cord and its nerve roots are put back inside the spine and covered with meninges. [62] 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. Myelomeningocele . If you need to speak with one of Shine's specialist advisers about spina bifida or hydrocephalus, call us on 01733 555988 or click here to email us. 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. [33], Many individuals with spina bifida have an associated abnormality of the cerebellum, called the Arnold Chiari II malformation. [65] To the mother, this includes scarring of the uterus. Read more on related conditions. Spina bifida is a condition in which a baby's spine doesn't properly develop, leaving a gap. Spina Bifida Cystica with Meningocele. [12] On average, in developed countries, including the United States, it occurs in about 0.4 per 1,000 births. 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). As a result, there is nearly always some resulting paralysis and loss of sensation. [36] Children with spina bifida may perform well in elementary school, but begin to struggle as academic demands increase. The second is via fetoscopy. However, most commonly it is used as a synonym or subset of spinal dysraphism. The Giessen experience 2010–2012. [15] The term spina bifida is Latin for "split spine". 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. [39] Unlike typically developing children, youths with spina bifida do not tend to improve in their executive functioning as they grow older. Surgeons at Vanderbilt University, led by Joseph Bruner, attempted to close spina bifida in 4 human fetuses using a skin graft from the mother using a laparoscope. [5] Spina bifida is a type of neural tube defect related to but distinct from other types such as anencephaly and encephalocele. [1] [14] Part of this difference is believed to be due to race, with Caucasians at higher risk, and part due to environmental factors. [66], Treatment of spina bifida during pregnancy is not without risk. Spina bifida occulta is common and happens in about 1 out of 10 people. 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. 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. For most people affected, SBO will have no impact on their lives. [21][22][23], However, other studies suggest spina bifida occulta is not always harmless. [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. [11] Open spina bifida can be surgically closed before or after birth. Spina bifida is a birth defect that occurs when the spine and spinal cord don't form properly. 1). [40] Further, children with spina bifida may have poor cognitive flexibility. This approach has been evaluated by independent authors of a controlled study which showed some benefit in survivors,[90] but others are more skeptical. Estimates vary, but between 5% and 10% of people may have spina bifida occulta. Development of the spinal cord may be affected, but impairment is usually less severe than myelomeningocele. [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. [citation needed], A meningocele may also form through dehiscences in the base of the skull. Features. [106][107] These papers suggested that the risk to the mother is small. There are a number of conditions that share features with, or are otherwise closely linked to spina bifida. Further, higher numbers of shunt revisions are associated with poorer mathematics abilities. In affected individuals, the back portion of the brain is displaced from the back of the skull down into the upper neck. [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. Although it can be uncomfortable to hear a diagnosis of spina bifida occulta, MRI can identify or exclude anything which might cause problems, so if your MRI shows no abnormalities other than a gap in the vertebrae, you should not experience any problems stemming from this finding. As the nervous system remains undamaged, individuals with meningocele are unlikely to suffer long-term health problems, although cases of tethered cord have been reported. Symptoms may include ambulatory problems, loss of sensation, deformities of the hips, knees or feet, and loss of muscle tone. [4] Alcohol misuse can trigger macrocytosis which discards folate. A systematic review of radiographic research studies found no relationship between spina bifida occulta and back pain. [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. [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). It is present from birth and is often seen as a skin covered lump on the baby’s back at birth. (The spinal cord may join up again, but if it doesn’t, it is referred to as diplomyelia.) [18] The splits in the vertebrae are so small that the spinal cord does not protrude. In this type, the involved area is represented by a flattened, plate-like mass of nervous tissue with no overlying membrane. The spine is a column of vertebral bodies (bones) with discs of fibrous tissue between them. 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. Girls are more prone to being born with spina bifida. Myelomeningocele is the most serious and more common of the two forms of cystic spina bifida. The macrocytosis of alcoholism usually reverses only after months of abstinence from alcohol", "Spina bifida Risk factors - Mayo Clinic", "Usual folic acid intakes: a modelling exercise assessing changes in the amount of folic acid in foods and supplements, National Health and Nutrition Examination Survey, 2003–2008", "Retrospective Assessment of Cost Savings From Prevention: Folic Acid Fortification and Spina Bifida in the U.S.", "Folic Acid - Public Health Agency of Canada", "Medical malpractice: Childbirth, failed to perform AFP test", "Fetal surgery for spina bifida: past, present, future", "Prenatal versus postnatal repair procedures for spina bifida for improving infant and maternal outcomes", "Center for Spina Bifida: Specialists and Services", "Acquisition of autonomy skills in adolescents with myelomeningocele", "Trajectories of autonomy development across the adolescent transition in children with spina bifida", "Psychosocial and family functioning in spina bifida", "Spinal dysraphism: A challenge continued to be faced by neurosurgeons in developing countries", "Trends in postfortification prevalence of spina bifida and ancephaly in the United States", "Background of Management of Myelomeningocele Study (MOMS)", "Management of Myelomeningocele Study (MOMS)", "A Randomized Trial of Prenatal versus Postnatal Repair of Myelomeningocele", "A randomized trial of prenatal versus postnatal repair of myelomeningocele", "Fetal endoscopic myelomeningocele closure preserves segmental neurological function", "Does fetal endoscopic closure of the myelomeningocele prevent loss of neurologic function in spina bifida aperta? This surgery aims to prevent further damage of the nervous tissue and to prevent infection; pediatric neurosurgeons operate to close the opening on the back. As a result, thinning of the uterine wall or dehiscence which have been among the most worrisome and criticized complications after the open operative approach do not occur following minimally invasive fetoscopic closure of spina bifida aperta. Medical imaging can confirm the diagnosis after birth. Spina bifida cystica: A bony defect in the vertebral column that causes a cleft in that column. Up to 20% of people have an incomplete formation of a single lamina in the lumbosacral spine without any other abnormalities. Spina Bifida Occulta. In spina bifida occulta, the meninges and/or neural tissue remain underneath skin. 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.
