A novel mutation in COL1A1 causing osteogenesis imperfecta/hearing loss.

Objectives: To screen the COL1A1 and COL1A2 gene mutation sites in a family with type I osteogenesis imperfecta (OI)/hearing loss and analyze the characteristics and recovery of hearing loss in patients with osteogenesis imperfecta.

Methods: The basic clinical data of OI proband and her parents were collected, and the COL1A1 and COL1A2 genes were detected in peripheral blood by PCR amplification and generation Sanger sequencing. Literature of stapedial surgery in patients with osteogenesis imperfecta was collected.

Comparison Between Multiple and Solitary Fungus Balls: A Retrospective Analysis.

Objectives: The most common type of noninvasive fungal rhinosinusitis is fungus ball (FB), which usually involves a solitary paranasal sinus. Multiple fungus balls (MFBs) are rarely reported in literature. The purpose of this study was to analyze and compare the clinical features of MFBs and solitary fungus ball (SFB).

Correction to: Efficacy and safety of delivery of topical medication on to the frontal sinus at different head positions after frontal sinusotomy.

In the original publication of the article, under the experimental protocol of the section "Clinical head position study in postoperative CRS patients", the following sentence "There were 20 CRS patients, 12 male and 8 female across an age range of 19-64 years…" was published incorrectly.

Efficacy and safety of delivery of topical medication on to the frontal sinus at different head positions after frontal sinusotomy.

Purpose: Effective topical medications delivery to the frontal sinus is crucial to recovery from frontal sinusotomy. However, finding a way to deliver local medications to the frontal sinus is still a major challenge. The objective of this study was to evaluate the influence of various head positions on postoperative frontal sinus drug deposition.

[Influence of different levels of skin pricking test on the short-term efficacy of subcutaneous immunotherapy in allergic rhinitis].

To explore the effect of different levels of skin pricking test on short-term efficacy of subcutaneous immunotherapy with allergic rhinitis.Thirty-one AR patients were included in our study.All the patients had received subcutaneous immunotherapy for 1 year.

Anatomy, classification of intersinus septal cell and its clinical significance in frontal sinus endoscopic surgery in Chinese subjects.

Background: Intersinus septal cell (ISSC) is not a very uncommon frontal recess cell. But it is poorly described in literature. The clinical significance of this anatomic variant still remains unclear.

[Effect of cycloxygenase 2 inhibitor on levels of prostaglandin E2 in plasma and in local infiltrated fluid after functional endoscopic sinus surgery].

Objective: To examine the time course and clinical relevance of changes in prostaglandin E2 (PGE2) to pain and outcome in surgical drainage, and circulating blood after functional endoscopic sinus surgery (FESS).

Methods: Thirty-seven patients scheduled to undergo FESS were randomized to receive celecoxib 400 mg(n=16) one hour before anesthesia induction and celecoxib 200 mg, q12 h for five consecutive days after surgery or nothing for patients in control group(n=21). Surgical site drainage and venous blood were collected up to 48 hours after surgery to test PGE2 level.

Association between HLA class II locus and the susceptibility to Artemisia pollen-induced allergic rhinitis in Chinese population.

Objective: The aim of the study was to determine whether susceptibility or resistance to Artemisia pollen-induced allergic rhinitis was associated with HLA class II DQA1, DQB1 loci. Study design and setting Forty-one subjects with allergic rhinitis and 41 healthy controls from Beijing were genotyped at HLA class II DQA1, DQB1 alleles by polymerase chain reaction amplification with sequence-specific primers-based technique.

Results: The allele frequencies of HLA-DQA1*0201, DQB1*0602 were lower in patients with allergic rhinitis compared with the controls (24.

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.
