Immunoglobulin G4-related disease (IgG4-RD) is a chronic inflammatory disease involving multiple organs. Some studies have reported otological manifestations of IgG4-RD, although most studies describe involvement of the middle ear, and reports on inner ear manifestations are limited. Here, we describe a case of a 30-year-old man with IgG4-RD involving the inner ear. This case demonstrated that IgG4-RD affected the inner ear and caused cochlear ossification. Cochlear implants may be considered for milder cases, and hormone and immunosuppressive therapy may control disease progression.

Chronic rhinosinusitis (CRS) is believed to be the result of an exaggerated reaction to fungi in the nasal mucosa, and topical amphotericin B (AMB) is a commonly used treatment. The purpose of this study was to perform a meta-analysis of high-quality comparative studies to examine the efficacy of topical AMB for the treatment of CRS. A search was conducted of Medline, Cochrane, EMBASE, and ISI Web of Knowledge until December 31, 2013 using combinations of the search terms chronic rhinosinusitis, human, treatment, antibiotics, nasal irrigation, nebulized, nasal lavage, sinonasal rinses, and antimicrobials. Inclusion criteria were (1) comparative studies, (2) a diagnosis of CRS or chronic sinusitis, and (3) the intervention was a topical antifungal. The primary outcome measure was quality of life (QOL), and the secondary was nasal endoscopy score. Of 235 article initially identified, five randomized controlled trials were included in the meta-analysis. Analysis of four studies with complete QOL data found no difference between treatment and placebo groups [standard difference in means 0.78, 95 % confidence interval (CI) -0.25 to 1.81, P = 0.138]. Analysis of four studies with complete nasal endoscopy score data found no difference between the treatment and placebo groups (standard difference in means 0.34, 95 % CI -0.08 to 0.76, P = 0.117). AMB is not more effective than placebo in improving QOL or nasal endoscopy scores in patients with CRS.

Stapediovestibular dislocation is a rare disorder as a result of traumatic injury to the structures in the middle ear. We described a case of a 60-year-old female with stapediovestibular dislocation with associated perilymph fistula. She presented with symptoms including hearing loss, vertigo, and tinnitus after a penetrating injury by an ear pick. After 4 months of conservative management, her symptoms failed to improve. Therefore, she underwent surgery which resolved completely her vestibular symptoms and her hearing loss had partially improved. The restoration of the stapes to its normal anatomical position coupled with ossiculoplasty and closure of the tympanic membrane are effective in patients with stapediovestibular dislocation.

Vehicle detection algorithm based on video analysis is negative for vehicle detection in complex scenes, such as traffic intersection, due to the single angle and the poor static detection effect, and so on. Aimed at above problems, this article proposes a multi-angle vehicle detection method, based on micro cascading neural network. This method improves the tertiary AdaBoost recursive model and constructs an embedded micro neural network model. This paper combining the model with local normalized pixel-value differencing (NPD) features, trained AdaBoost model by polymorphic complex angle samples. The results show that the method has better detection performance and lower failure rate, and average detection rate and detection time are 89.47% and 199 ms respectively, which can meet the requirements of real-time vehicle detection in actual scene.
