Epithelial migration in open mastoidectomy cavities.

Objective: To study the rate and pattern of epithelial migration in 18 dry, open mastoidectomy cavities.

Methods: This was a prospective study of 19 patients who had undergone mastoidectomy at a secondary (state) hospital and a tertiary referral centre at least 6 months previously and whose mastoid cavities were dry and not infected. Their mastoidectomy cavities were cleaned and India ink dots applied in its medial aspect under microscope.

Characterization of a new SNP c767A/T (Arg222Trp) in the candidate TSG FUS2 on human chromosome 3p21.3: prevalence in Asian populations and analysis of association with nasopharyngeal cancer.

The FUS2 gene, encoding a novel cytoplasmic acetyltransferase, resides in the tumor suppressor gene region on human chromosome 3p21.3 and is considered a promising candidate tumor suppressor gene. We have identified a new single nucleotide polymorphism (SNP), c767A/T, in the coding region of the gene.
