Paralysis discount phenamax 60caps on line, incontinence buy discount phenamax 60 caps on line, obesity, endo- crinopathy, hydrocephalus, short stature, social stigmata, and shortened lifespans are still the norms for children with open neural tube defects (NTDs). Clinical and epidemiological studies in humans have implicated maternal illnesses, medications, environmental toxins, and dietary factors such as folic acid that play causative or at least contributing roles in NTD develop- ment. Febrile illnesses and hyperthermia produced by the use of a sauna or hot tub early in pregnancy have been also suggested as causes of NTDs. Some genes may confer strong genetic components and others may © 2005 by CRC Press LLC only exert minimal direct effects or require interaction with other genes. Empiric studies have shown that the recurrence risk for NTD is greatest among first-degree relatives of an affected patient and decreases for more distant relatives. The recurrence risk for siblings of an affected patient is 2 to 5%, representing a 25- to 50-fold increase in recurrence risk compared to the general population. The six well-known mutations are splotch (Sp),43–45 extra toes (Xt),46 short tails (T),47 patch (Ph),48 and targeted mutations in apolipo- protein B (ApoB)49 and Hox-a1. Determination of dorsoventral (DV) and anteroposterior (AP) domains during gastrulation appears critical for normal neural development. The posterior mesoderm (notochord) induces competent ectoderm to form the deuterencephalon (metencephalon, myelencephalon, cerebel- lum) and spinal cord. Primary neurulation71 begins after gastrulation when the primitive ectoderm is induced by the axial meso- derm to form a neural plate. Primary neurulation forms all functional levels of the brain and spinal cord to the second sacral level in humans. The caudal elements of the spinal cord, conus medullaris and filum terminale, are formed by secondary neurulation,72–78 which begins at a transitional zone where the dorsally located primary neural tube overlaps the more ventral mesenchymal cells of the tail bud in the future lumbosacral area. Recent evidence in chick embryos suggests that cells may migrate from more rostral neural plates to attain their proper positions in the secondary neural tubes. Governing factors in the caudal neural tube pattern such as the brachyury and Pax-3 patterning genes have not been identified as major factors in spinal dysraphism.
