Increased nuchal translucency and diaphragmatic hernia. A case report.

Increased nuchal translucency (NT) thickness is present in 40% of fetuses with diaphragmatic hernia, including 80% of those that result in neonatal death and in 20% of the survivors. A 33-year-old nulliparous woman had first trimester scan at 12 weeks. The fetus had a NT of 2.

Novel karyotypic changes detected by comparative genomic hybridization in a case of congenital cervical immature teratoma.

Background: Cervical immature teratoma is a rare congenital tumor, and very few cases have been studied cytogenetically.

Case: In this article, we describe a case of this tumor type and present the findings of the karyotype of the lesion, which was performed with the bacterial artificial chromosome arrays using the comparative genomic hybridization method. The chromosomal abnormalities that we found included an amplification on 1p21.

Treponema denticola (ex Brumpt 1925) sp. nov., nom. rev., and identification of new spirochete isolates from periodontal pockets.

Standard growth and isolation methods were used to obtain five new treponema strains in pure culture from deep periodontal pockets. The strains were identified to the species level by various methods, including agglutination, immunofluorescence, a dot blot immunoassay, electron microscopy, gas-liquid chromatography of metabolic volatile fatty acids, and DNA hybridization. Two isolates were strains of Treponema socranskii; the other three were strains of "Treponema denticola," a species described in 1925 by Brumpt.
