PEDIATRICS

Title: Posterior Fossa Decompression with or without Duraplasty for Chiari type I Malformation with Syringomyelia
Investigator: Bermans J. Iskandar, MD
Study Sponsor: PCORI (Patient-Centered Outcomes Research Institute)

Chiari type I malformation and Syringomyelia is treated with neurosurgical decompression of the craniocerebral junction with either of two technical variations: posterior fossa decompression with duraplasty (PFDD) or posterior fossa decompression without duraplasty (PFD) The Hypothesis of this study is that PFD will be associated with fewer surgical complications and less harm to patients that PFDD. The University of Wisconsin School of Medicine and Public Health and the American Family Children’s Hospital are one of 47 clinical sites across the United States participating in this study.

Title: HCRN. Hydrocephalus Clinical Research Network Core Data Project: Characterizing Patients Populations within the HCRN

Title: DNA Methylation in Familial Chiari I Malformation
Investigator: Dr. Bermans Iskandar, MD and Dr. Reid Alisch, PhD
Sponsor: The American Syringomyelia & Chiari Alliance Project (ASAP)

This study hypothesizes that familial Chiari I is epigenetic in origin, and proposes to employ a whole genome DNA methylation approach on tissues obtained from familial Chiari I subjects and unaffected controls. While evidence that Chiari I can be inherited continues to accumulate, a unified genetic basis or mode of inheritance has not been identified.

Title: DNA Methylation in Spina Bifida
Investigator: Dr. Bermans Iskandar, MD and Dr. Reid Alisch, PhD
Sponsor: ICTR Translational Basic & Clinical Pilot Award RFA – University of Wisconsin-Madison

This study hypothesizes that epigenetic modifications contribute to heritable conditions that can be influenced by environmental factors without a change in the DNA sequence. Thus, we believe that alterations in epigenetic modifications cause inherited forms of spina bifida that lack an obvious genetic predisposition but have perceptible links to environmental conditions. Findings from this research will provide critical molecular insights into the heritable basis of these malformations.
