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 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). One study found that among patients with back pain, severity is worse if spina bifida occulta is present. [57] However it is difficult for women to get the recommended 400 micrograms of folic acid a day from unfortified foods. [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. Children with spina bifida are more likely than their peers without spina bifida to be dyscalculic. Spina bifida cystica can then be broken down into meningocele and myelomeningocele. Treatment usually involves surgery to remove the bone and to free up the spinal cord (. The second type of spina bifida is called meningocele or spina bifida cystica with meningocele. Spina bifida is present from birth and can take several forms. [1] It falls under the broader category of neural tube defects. Indeed, the association of foot deformities with sacral hypertrichosis may be the origin of the mythological figure of the satyr . The second is via fetoscopy. Related conditions Spina bifida was described in the medieval literature and was recognized even earlier. However, dietary supplementation with folic acid has been shown to be helpful in reducing the incidence of spina bifida. [98][99][100][101][102][103][104][105][excessive citations], Since then more data has emerged. 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. [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. [12], Spina bifida with myelocele is the most severe form of myelomeningocele. MMC is a failure of this to occur completely. Women who have already had a baby with spina bifida or other type of neural tube defect, or are taking anticonvulsant medication, should take a higher dose of 4–5 mg/day. [10], Toxins and conditions associated with MMC formation include: calcium-channel blockers, carbamazepine, cytochalasins, hyperthermia, and valproic acid. People without the extra bone only occasionally develop symptoms, if the cord becomes tethered. Spina= Latin: “spine” Bifida= Latin:“split”Occulta = Latin: “hidden.” (Unlike in “open” spina bifida, the defect in spina bifida occulta is not visible. spina bifida cystica in particular have assumed greater importance in recent years. [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. With this condition, a sac of fluid comes through an opening in the baby’s back. Types of Spina Bifida. With it, there is a small gap in the spine, but no opening or sac on the back. 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. Shine uses browser cookies to give you the best possible experience. German Society for Prenatal Medicine and Obstetrics, International Society of Obstetrics and Gynecology, "Are there disorders or conditions associated with spina bifida? [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. There is no known cure for nerve damage caused by spina bifida. In one study, 60% of children with spina bifida were diagnosed with a learning disability. [39], Individuals with spina bifida, especially those with shunted hydrocephalus, often have attention problems. The common use of latex in medical facilities makes this a particularly serious concern. [8] Rates of other types of spina bifida vary significantly by country from 0.1 to 5 per 1000 births. [7] In the United States it affected about 0.7 per 1000 births,[4] and in India about 1.9 per 1000 births. 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). 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. You may not know, but there are a number of different types of spina bifida. Myelomeningocele occurs in the third week of embryonic development, during neural tube pore closure. Four cases were performed before stopping the procedure - two of the four fetuses died. [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. 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. Symptoms may include ambulatory problems, loss of sensation, deformities of the hips, knees or feet, and loss of muscle tone. 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. [31] Neurons within the cortex may also be displaced. Although executive functions are often attributed to the frontal lobes of the brain, individuals with spina bifida have intact frontal lobes; therefore, other areas of the brain may be implicated. Degenhardt J, Kawecki A, Enzensberger C, Stressig R, Axt-Fliedner R, Kohl T. "Reversal of hindbrain herniation within a few days after minimally-invasive fetoscopic surgery for spina bifida indicates the desired water-tight closure of the lesion. Encephalomeningoceles are classified in the same way and also contain brain tissue. 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. This is the mildest form of spina bifida. 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. 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. [71] An increased dependence on others (in particular family members) may interfere with the adolescent's self-management of health-related tasks, such as catheterization, bowel management, and taking medications. There may be a hairy patch, dimple, or birthmark over the area of the defect. [39] Unlike typically developing children, youths with spina bifida do not tend to improve in their executive functioning as they grow older. The spinal cord and its nerve roots are put back inside the spine and covered with meninges. In some individuals, this causes significant traction and stress on the spinal cord and can lead to a worsening of associated paralysis, scoliosis, back pain, and worsening bowel and/or bladder function. As lipomyelomeningocoele is skin covered, no ‘back closure’ surgery is needed at birth. 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’. The prevalence varies across time, by region and by both race and ethnicity. Research has shown the lack of folic acid (folate) is a contributing factor in the pathogenesis of neural tube defects, including spina bifida. 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. Spina Bifida Occulta is the mildest type of spina bifida. The term ‘spina bifida occulta’ is sometimes used to refer to other skin covered lesions (such as lipomyelomeningocoele or diastematomyelia - see below) but it is more accurate to distinguish between those conditions, and uncomplicated gaps in the vertebrae. There are two types: spina bifida occulta and spina bifida cystica. There are a number of conditions that share features with, or are otherwise closely linked to spina bifida. [7][4][13] In India, it affects about 1.9 per 1,000 births. This approach has been evaluated by independent authors of a controlled study which showed some benefit in survivors,[90] but others are more skeptical. These fat cells prevent the spinal bones closing completely, leaving the ‘spina bifida’ gap. In spina bifida occulta, the meninges and/or neural tissue remain underneath skin. ", "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. These may be classified by their localisation to occipital, frontoethmoidal, or nasal. It is the most common type of spina bifida. [54][55][56] It is unknown how or why folic acid has this effect. Shine, 42 Park Road, Peterborough, PE1 2UQCall: 01733 555988    Email: info@shinecharity.org.uk, Copyright Shine 2018, Registered Charity No: 249338 | Registered in London no. [5][1] Meningocele typically causes mild problems, with a sac of fluid present at the gap in the spine. Need more help? This risk can be reduced with folic acid supplementation before pregnancy. [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. 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. This is the most common and serious type of spina bifida. [37] Deficits have been observed for selective attention and focused attention, although poor motor speed may contribute to poor scores on tests of attention. [5] Spina bifida is a type of neural tube defect related to but distinct from other types such as anencephaly and encephalocele. According to the Spina Bifida Association, 10 to … [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). In children, this can be a normal part of development, with some of the lowest vertebrae not closing completely until the teenage years. For a small number of people with spina bifida occulta the fault is more extensive. As a result, there is nearly always some resulting paralysis and loss of sensation. Open spina bifida can usually be detected during pregnancy by fetal ultrasound. With modern medical care, the quality of life of patients has greatly improved. [2] Learning problems are relatively uncommon. [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. In this form, a single developmental defect allows the meninges to herniate between the vertebrae. Myelomeningocele is the most serious type of spina bifida. In 2014, two papers were published on fifty one patients. [27] In individuals with myelomeningocele, the unfused portion of the spinal column allows the spinal cord to protrude through an opening. However, for some people, there are associated conditions which can have a significant impact on their lives and abilities. It is only present along the spinal cord [2]. Thinner sections of the brain are also associated with increased cortical folding. [33], Many individuals with spina bifida have an associated abnormality of the cerebellum, called the Arnold Chiari II malformation. 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. For most people with spina bifida occulta, one vertebra in the lower back is slightly open. [48] Comprehension may be especially impaired for text that requires an abstract synthesis of information rather than a more literal understanding. [19] About 15% of people have spina bifida occulta,[8] and most people are diagnosed incidentally from spinal X-rays. About 15% of people have spina bifida occulta. Other times, there may be no abnormalities in the area. Learn about the most common and severe form of spina bifida, myelomeningocele (MMC), and the long-term complications. In normal circumstances, the closure of the neural tube occurs around the 23rd (rostral closure) and 27th (caudal closure) day after fertilization. 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. The Giessen experience 2010–2012. 1). Anatomy scan of the fetal head at 20 weeks of pregnancy in a fetus affected by spina bifida. Spina Bifida Cystica with Meningocele. Neural arch formation occurs in the first month of embryonic development (often before the mother knows she is pregnant). It is a rather common condition, occurring in about 10-20% of people. [65] To the mother, this includes scarring of the uterus. [65], Broadly, there are two forms of prenatal treatment. The highest incidence rates worldwide were found in Ireland and Wales, where three to four cases of myelomeningocele per 1000 population have been reported during the 1970s, along with more than six cases of anencephaly (both live births and stillbirths) per 1000 population. These techniques may be an option to standard therapy. Spina bifida cystica: A bony defect in the vertebral column that causes a cleft in that column. [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. RESULTS: Eighteen infants diagnosed with spinal NTDs (prevalence 1.6/10,000) included 13 with spina bifida cystica and 5 with spina bifida occulta. In occulta, the outer part of some of the vertebrae is not completely closed. The exposed spinal cord is damaged by the fluid in the womb during pregnancy and may also not develop properly. Provided the spinal cord or nerves are not affected, there should be no impact on walking or bladder and bowel function. If this development doesn't work properly, a baby will be born with a 'neural tube defect' (NTD), of which spina bifida is one. 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. Many times, Spina Bifida Occulta is not discovered until late childhood or adulthood. [citation needed], X-ray image of spina bifida occulta in S-1, X-ray computed tomography scan of unfused arch at C1, Myelomeningocele in the lumbar area(1) External sac with cerebrospinal fluid(2) Spinal cord wedged between the vertebrae.
