Using array comparative genome hybridisation (CGH) 41 de novo reciprocal translocations and 18 de novo complex chromosome rearrangements (CCRs) were screened. All cases had been interpreted as "balanced" by conventional cytogenetics. In all, 27 cases of reciprocal translocations were detected in patients with an abnormal phenotype, and after array CGH(More)
Epilepsy is commonly observed in patients with chromosomal aberrations. We evaluated epilepsy and electroencephalographic (EEG) features in a group of patients carrying aberrations of chromosome 18. Fourteen patients were recruited: five with an 18p deletion syndrome (18pDS); six with an 18q deletion syndrome (18qDS); two with trisomy 18p syndrome; and one(More)
A de novo, apparently balanced complex chromosome rearrangement (CCR) involving five chromosomes and six chromosome breakpoints was found in a child with Marfanoid habitus, kyphoscoliosis, axillary pterygium, camptodactyly, joint laxity, and mild mental retardation. Fluorescence in situ hybridization (FISH) revealed a simple translocation involving(More)
AIMS The purpose of this study was to establish whether the cell proliferation index assessed by the monoclonal antibody MIB-1 would correlate with survival in pleural malignant mesothelioma. METHODS AND RESULTS We studied a series of seven long-term survivors with pleural malignant mesothelioma and a group of control cases with short-term survival. All(More)
A 13 year old male with a severe progressive neurological disorder was found to have a pseudodicentric chromosome resulting from a telomeric fusion 15p;20p. In lymphocytes, the centromeric constriction of the abnormal chromosome was always that of the chromosome 20, while in fibroblasts both centromeres were alternately constricted. Cd staining was positive(More)
CONTEXT Several aspects of sweat gland carcinomas (incidence, classification, diagnosis, and behavior) have not been definitively clarified and need to be studied further. OBJECTIVE The clinicopathologic findings of a large series of sweat gland carcinomas, collected during a period of 15 years, are presented. METHODS Sixty sweat gland carcinomas (41(More)
Facial hemangioma is usually isolated but its association with craniocervical arterial anomalies and structural brain malformations is well known. The acronym PHACE syndrome (posterior fossa malformation, facial hemangiomas, arterial anomalies, cardiac/aortic anomalies, and eye abnormalities) has been used to indicate that disorder in which brain anomalies(More)
