What are neural tube defects?

What are neural tube defects?

NTD: Neural tube defects are a host of lesions that affect the spinal cord. They vary in degree from spina bifida occulta ( mildest ) to craniorrachischis totalis ( severest), spina bifida, and myelomengocele being the most frequently encountered. They have been linked to a diet deficient in folate (folic acid) during pregnancy. ...Read more

Are neural tube defect babies active?

Are neural tube defect babies active?

Possibly: It depends on multiple factors. There are different degrees of neural tube defects. Some people can have a mild defect and other may have a severe defect. It also depends on the location of the defect. Your doctor might be able to better answer this question with all of the relevant information. ...Read more

Is arnold chiari malformation type one a neural tube defect?

Is arnold chiari malformation type one a neural tube defect?

No: The more accepted term is chiari malformation as arnold-chiari is an older term. This type of malformation is not a neural tube defect, but rather an abnormal migration of the cerebellar tonsils below the level of the foramen magnum (chiari type 1). This defect is attributed to a congenitally small posterior fossa, thus allowing the cerebellar tonsils to migrate downward. ...Read more

What is neural tube defects often mentioned in pregnancy..?

Spina Bifida: "neural tube defects" is a general name for developmental problems regarding the early developing spinal cord. The most commonly known defect is called "spina bifida" -- a defect in which the developing spinal cord is open to the skin on the back of the baby. This can lead to bowel or bladder control problems, neurologic problems, and even paralysis. ...Read more

Afp normal, enlarged brain ventricles, is it still possible to have a neural tube defect ntd?

Afp normal, enlarged brain ventricles, is it still possible to have a neural tube defect ntd?

AFP: A normal AFP reduces the risk of an open neural tube abnormality. Enlarged cerebral ventricles are usually not associated with neural tube abnormalities. ...Read more

What is the best neural tube defect test?

NTD: The "best" test is an amniotic fluid AFP concentration. That picks up about 90% of open neural tube defects. However, an ultrasound examination also picks up the majority of open neural tube defects. ...Read more

What are the tests for neural tube defects?

Antepartum Dx.: There are screening tests available to detect neural tube defects in the fetus. The most common is called alfa fetoprotein. The levels of this substance is significantly increased if the fetus is affected with an open neural tube defect. ...Read more

Eustachian tube dysfunction or patulous eustachian tube, what's the difference?

Eustachian tube dysfunction or patulous eustachian tube, what's the difference?

Ear tube issues: The two terms relate to the state of the eustacian tube and the consequences of that state.The patuous description implies the eustacian tube does not open and close in a normal manner. If you station tube is not open and close it is deemed to have dysfunction. This dysfunction may result in autophony, a sensation of hearing an echo in one's head. ...Read more

Is spina bifida caused by a spinal cord injury or chromosomal disorder?

Is spina bifida caused by a spinal cord injury or chromosomal disorder?

No one knows : There seems to be an interplay of genetic and environmental factors that cause this disease. Women who have had one child with spina bifida, or who are obese or diabetic have an increased chance of having a child with the problem. It is known that taking Folic Acid during the fertile years decreases the chance of having this problem. ...Read more

What is eustachian tube dysfunction, bilateral?

As follows.: The main symptom is muffled or dulled hearing. You may also have ear pain because the eardrum is tensed and stretched. Other symptoms that may also develop include a feeling of fullness in the ear, ringing or buzzing in the ear (tinnitus) and dizziness. One or both ears may be affected. See ENT doc to manage this problem. ...Read more

What causes spina bifida? Is spina bifida caused by a spinal cord injury, or a chromosomal disorder?

What causes spina bifida? Is spina bifida caused by a spinal cord injury, or a chromosomal disorder?

Spina : Spina bifida is not an injury. It is a birth defect caused by failure of the nervous system to fully develop. When the embryo is forming, the nervous system starts out as a "neural tube" that is supposed to grow in a very specific way. If it does not, you are left with "neural tube defects" like spina bifida. There is nothing we know of that causes it for sure, but certain things make it more likely. It is more common with children that have trisomy 13, 18, or 21, but that is just an association, not a cause. They are very common, and the only thing we know of that might help prevent them is for the mother to take folate (folic acid). The hard part about that is the mother has to take folate (folic acid) very early in the pregnancy, often before she even knows she is pregnant. That is why the all women of child-bearing age are advised to take at least 0.4 mg of Folic Acid every day. ...Read more

Does fallopian tube recanalization work?

Does fallopian tube recanalization work?

Sometimes yes!: It depends on the patient and the reason the tube(s) is (are) blocked. Tubal cannulation under fluoroscopy and by hysteroscopy have both been studied extensively since the early 1990s (it was actually first done with a whale bone in the 1890s!) the most important consideration is whether the woman is a appropriate candidate for the procedure. ...Read more

Doctors, what is the difference between neural tube and dorsal nerve cord?

Doctors, what is the difference between neural tube and dorsal nerve cord?

Notochord: notochord is formed on day 17 gestation this then secretes signalling molecules like SHH protien that induces overlying ectoderm to neuroectoderm this produces precurser cells for neural structures in the embrayo the notochord then forms the axis of developing vertebral body in the developing embrayo during primary nurulation the neuroectoderm forms a neural tube and spinal tube ...Read more
