PURPOSE To perform an extensive systematic review to examine all the available literature reporting iatrogenic acquired arteriovenous malformation (AVM) induced after diagnostic curettage and to describe a further case of a 34-year-old woman presenting with acute vaginal bleeding due to AVM induced after uterine curettage for termination of pregnancy.

Recently, rare mutations in the TARDBP gene have been identified in familial and sporadic amyotrophic lateral sclerosis (ALS) patients. The purpose of this study was to characterize the genetic variability of the TARDBP gene in a cohort of Sardinian ALS patients. The coding region of the gene was analyzed in 97 unrelated patients previously tested negative(More)
Full monosomy 21 is an extremely rare chromosomal disorder. A 38-year-old woman attended a first trimester scan. Ultrasound (U/S) imaging of the fetus at 12 weeks of gestation showed features of increased nuchal translucency measurement (12 mm). Chorionic villi sampling (CVS) was performed after genetic counseling. At 16 weeks of gestation the fetus showed(More)
The genetic diagnosis of mental retardation (MR) is difficult to establish and at present many cases remain undiagnosed and unexplained. Standard karyotyping has been used as one of the routine techniques for the last decades. The implementation of Array Comparative Genomic Hybridization (array-CGH) has enabled the analysis of copy number variants (CNVs)(More)
OBJECTIVE Evaluate the results obtained from Quantitative Fluorescent (QF)-PCR and conventional karyotype analysis to determine the advantages and disadvantages of dual testing in prenatal diagnosis. METHODS From 1 June 2006 to 1 June 2010, dual testing by QF-PCR and karyotype analysis was performed in 13,500 prenatal samples. The rates of concordant(More)
Polymorphisms of the cytotoxic T-lymphocyte antigen-4 gene (CTLA-4) have been associated with autoimmune diseases and it has recently been reported that donor genotypes correlate with the outcome of allogeneic hematopoietic stem cell transplantation in leukemia patients. With the aim of confirming this finding in thalassemia patients, we investigated the(More)
Twenty-nine as yet unreported ring chromosomes were characterized in detail by cytogenetic and molecular techniques. For FISH (fluorescence in situ hybridization) previously published high resolution approaches such as multicolor banding (MCB), subcentromere-specific multi-color-FISH (cenM-FISH) and two to three-color-FISH applying locus-specific probes(More)
Tetrasomy 9p is a rare chromosomal syndrome and about 30% of known cases exhibit mosaicism. Approximately 50 of the reported cases with tetrasomy 9p mosaicism show a characteristic facial appearance, growth failure, and developmental delay. However, 3 patients with mosaicism for isochromosome 9p and a normal phenotype have also been reported. We report 2(More)
Traditional approaches for the classification of Small Supernumerary Marker Chromosomes (sSMC), mostly based on FISH techniques, are time-consuming and not always sufficient to fully understand the true complexity of this class of rearrangements. We describe four supernumerary marker chromosomes that, after array-CGH, were interpreted rather differently in(More)
BACKGROUND Down syndrome (DS) is the most common aneuploidy in live-born individuals and it is well recognized with various phenotypic expressions. Although an extra chromosome 21 is the genetic cause for DS, specific phenotypic features may result from the duplication of smaller regions of the chromosome and more studies need to define genotypic and(More)
