[Endoscopic repair of nasal septal perforation with acellular dermal matrix and pedicled mucoperichondrial flap].

Objective: To introduce the method and evaluate the efficacy of endoscopic repair of nasal septal perforation with acellular dermal matrix and pedicled mucoperichondrial flap.

Methods: Twelve patients with perforation of nasal septum were encountered since February 2006 to October 2010. The most common symptoms and sings were nasal obstruction and crusting at the margin of the perforation.

[Diagnosis and endoscopic treatment of sphenoid mycetoma].

Methods: The clinical data and the follow-up results of endoscopic surgery in 23 patients with sphenoid mycetoma, between April 2001 and January 2006, were retrospectively analysed.

Results: The study population included 15 women and 8 men with a median age of 52.

A common IL-13 Arg130Gln single nucleotide polymorphism among Chinese atopy patients with allergic rhinitis.

Allergic rhinitis is a major public health problem and has seen its prevalence increase during the past few decades. Interleukin 13 (IL-13) has been implicated in the pathogenesis and in the regulation of immunoglobulin E (IgE) production. Single nucleotide polymorphisms (SNPs) have been found in both the coding sequence and the promoter region of IL-13, and such SNPs have been associated with allergic asthma.
