The DYT6 gene for primary torsion dystonia (PTD) was mapped to chromosome 8p21-q22 in two Amish-Mennonite families who shared a haplotype of marker alleles across a 40 cM linked region. The objective of this study was to narrow the DYT6 region, clinically characterize DYT6 dystonia in a larger cohort, and to determine whether DYT6 is associated with dystonia in newly ascertained multiplex families. We systematically examined familial Amish-Mennonite dystonia cases, identifying five additional members from the original families, as well as three other multiplex Amish-Mennonite families, and evaluated the known DYT6 haplotype and recombination events. One of the three new families carried the shared haplotype, whereas the region was excluded in the two other families, suggesting genetic heterogeneity for PTD in the Amish-Mennonites. Clinical features in the five newly identified DYT6 carriers were similar to those initially described. In contrast, affected individuals from the excluded families had a later age of onset (46.9 years vs. 16.1 years in the DYT6), and the dystonia was both more likely to be of focal distribution and begin in the cervical muscles. Typing of additional markers in the DYT6-linked families revealed recombinations that now place the gene in a 23 cM region surrounding the centromere. In summary, the DYT6 gene is in a 23 cM region on chromosome 8q21-22 and does not account for all familial PTD in Amish-Mennonites.
A low overall rate of ureteral access failure in unstented patients is shown. Young female patients and proximal ureteral stones were less likely to be accessed primarily. This study provides information that will help urologists counsel their patients preoperatively regarding their likelihood of failing primary URS necessitating a second procedure. This will also help the patient to make an informed decision during the consent process and may guide urologists on selective prestenting in higher risk patients.
Low-risk cases today have substantially lower tumor volume and PSA levels than low-risk cases diagnosed in 1998, indicating that outcomes in studies that recruited cases in previous decades represent worst case scenarios.
Recipients with a high anti-inflammatory and immune-regulatory genetic profile (high interleukin-10) were protected from RHC. Conversely, recipients with a pro-apoptotic genetic profile (high Fas) or high angiotensin-1-converting enzyme producing genotype were at increased risk of RHC. This represents progress toward understanding the genetic risk factors of posttransplantation outcomes in pediatric heart recipients.
We found a decrease in the incidence of concomitant anti-incontinence procedures at the time of pelvic organ prolapse repair following the 2011 FDA notification despite no significant decline in subjective stress urinary incontinence or demonstrable stress urinary incontinence on preoperative evaluation. Further analysis is warranted to assess the impact of the FDA notification on treatment patterns in women with pelvic organ prolapse and stress urinary incontinence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
