Clinical and molecular observations of two fatal cases of rotavirus-associated enteritis in children in Italy.

ABSTRACT: Two fatal cases of infantile rotavirus enteritis occurred in northern Italy in 2005. Both children were severely dehydrated, and death was related to severe cerebral edema. Histological examination demonstrated extensive damage of the intestinal epithelium, villous atrophy or blunting, and macrophage infiltration. The two rotavirus strains were of the G1P[8] type and the long electropherotype. The 2005 G1P[8] rotaviruses differed in the NSP4, VP3, VP4, and VP7 genes from G1P[8] rotaviruses circulating in 2004, suggesting the onset of a new G1P[8] strain in the local population.

Project description:Crouzon syndrome, a dominantly inherited disorder and the most common type of craniosynostosis syndrome, is caused by mutations in the fibroblast growth factor receptor 2 (FGFR 2) gene, and characterized by craniosynostosis, shallow orbits, ocular proptosis, midface hypoplasia and a curved, beak?like nose. The purpose of the present study was to investigate the fibroblast growth factor receptor 2 (FGFR 2) gene in two Chinese families with Crouzon syndrome and to characterize the associated clinical features. Two families underwent complete ophthalmic examination, and three patients in two families were diagnosed with Crouzon syndrome. Genomic DNA was extracted from leukocytes of peripheral blood samples, which were collected from the family members and 200 unrelated control subjects from the same population. Exons 8 and 10 of the FGFR 2 gene were amplified using polymerase chain reaction analysis and were directly sequenced. Ophthalmic examinations, including best?corrected visual acuity, slit?lamp examination, fundus examination and Computerized Tomography scans, and physical examinations were performed to exclude systemic diseases. These patients were affected with shallow orbits and ocular proptosis, accompanied by midface hypoplasia, craniosynostosis, strabismus or papilloedema, with clinically normal hands and feet. A heterozygous FGFR 2 missense mutation, c.811?812insGAG (p.273insGlu) in exon 8 was identified in the affected individual, but not in the unaffected family members or the normal control individuals in family 1. In family 2, another heterozygous FGFR 2 missense mutation, c.842A>G (P.Tyr281Cys or Y281C), in exon 8 was identified in the affected boy and his mother, but not in the unaffected family members or the normal control individuals. Although FGFR 2 gene mutations and polymorphisms have been reported in various ethnic groups, particularly in the area of osteology, the present study reported for the first time, to the best of our knowledge, the identification of two novel FGFR 2 gene mutations in Chinese patients with Crouzon syndrome.
