Clinical Observation of Various Types of Idiopathic Hypertrophic Cranial Pachymeningitis.

BACKGROUND: To assist doctors in making better treatment decisions and improve patient prognosis, it is important to determine which therapy modalities are suitable for various forms of idiopathic hypertrophic cranial pachymeningitis (IHCP). METHODS: All cases were received from the hospital medical record system, and some follow-up information was gathered through telephone follow-up. RESULTS: A total of 26 patients, 14 men and 12 women, with ages ranging from 20 to 73 years and a mean of 47.42 years, were included in the research. Regular types were less likely to recur than irregular and nodular types, focal types were less likely to recur than diffuse types, and corticosteroid-refractory types were more likely to recur than corticosteroid-sensitive types. CONCLUSIONS: The extent and shape of the lesion and susceptibility to corticosteroids are potential factors that could influence recurrence. Futhermore, this paper also proposes the fibroblasts as a new therapeutic target which may improve the quality of prognostic survival of patients.

Traumatic Stapediovestibular Dislocation With Intact Stapes: Report and Review.

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.

Otological IgG4-Related Disease With Inner Ear Involvement: A Case Report and Review of Literature.

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.

The effectiveness topical amphotericin B in the management of chronic rhinosinusitis: a meta-analysis.

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.

[Endoscopic skull base surgery under the guidance of image navigation technology].

OBJECTIVE: To investigate the feasibility of image navigation technology in endoscopic skull base surgery. METHODS: This study consisted of 75 patients who underwent the endoscopic operations with the help of the image navigation system by the same surgeon between March 2010 and March 2013. The time to prepair image navigation system, identifying anatomical structure, complications, tumor resection, and follow-up results were analysed. RESULTS: The application of image navigation technology in the endoscopic skull base operations was both safe and reliable for delineation of tumors and identification of vital structures hidden or encased by the tumors, such as internal carotid artery, optic canal, comb, saddle bottom, foramen rotundum, foramen ovale, foramen lacerum, jugular foramen, cerebral dura mater. The tumor was removed completely, subtotally, or partially. All patients were successfully registered with accuracy, and the preoperative time was 8-15 minutes for preparation, 11 minutes in average. The target error was less than or equal to 1.5 mm. With guidance of the image navigation system, all patients were successfully operated on without serious complication. There were 13 cases with anterior skull base tumor, all were removed completely. There were 28 cases with sella region tumor, 21 totally resected, 7 subtotally resected. There were 20 cases with petroclival region tumor, 12 totally resected, 5 subtotally resected, 3 partially resected. There were 14 cases with pterygopalatine fossa and/or infratemporal fossa region tumor, 11 totally resected, 3 subtotally resected. All patients were available for follow-up (mean = 26 months) except 6 cases. CONCLUSION: Image navigation technology can be applied in endoscopic skull base operations with advantages of accurately locating, clearly marking, significantly decreasing incidence of complications, and maximally removing the lesions.

[Hearing impairment in patients with mild cognitive impairment and Alzheimer's disease].

OBJECTIVE: To study the relationship between the degrees of peripheral auditory dysfunction and clinical dementia rating (CDR) in the patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). METHODS: Pure-tone thresholds (PT), word recognition scores (WRS), acoustic immittance and auditory brain-stem responses (ABR) were done to evaluate the auditory function in 24 cases of the patients with MCI and in 31 cases of the patients with AD and in 50 subjects of the control group. Clinical dementia rating (CDR) questionnaire was used to define the dementia degree of the subjects. RESULTS: Twenty-four MCI patients and 31 AD patients were selected, with average age of 72.0 +/- 6. 5 and 73.1+/-7. 5 of whom 70.8% and 67.7% were female separately. There was no significant difference in PTT and WRS between the MCI and AD groups (P > 0.05). In order to ascertain the relationship between hearing level and degree of dementia, all subjects were divided into 4 groups according their hearing loss (PTA <25 dB:0, 25-30 dB:1, 31-35 dB:2, >35 dB:3) to compare their CDR scores (the control:0, MCI:0. 5, mild AD:1). The more the CDR scores have, the more hearing impairment after controlling the confounder factors (Kendalls tau b = - 0.285, P = 0.018). No significant difference was found between the two groups in audiometry reliability, acoustic immittance and ABR (P > 0.05). CONCLUSION: The positive relationship was founded the peripheral hearing impairment and the score of CDR questionnaire in less than 0.5 score of CDR groups and mild AD patients.

[Hearing impairment in senile dementia of Alzheimer's type].

OBJECTIVE: To evaluate the pure tone hearing threshold and word recognition score of senile dementia of the Alzheimer's disease (AD) patients, and to analyze the relationship between hearing loss and the cognition impairment. METHODS: Pure tone audiometry, word recognition score (WRS), acoustic immittance and auditory brainstem response (ABR) are used to evaluate the auditory function of 43 patients with AD and 50 subjects of the control group. The confounding factors are controlled. RESULTS: The average age of 43 dementia patients was 72.7 +/- 6.4, and 69.7% was female. Bilateral hearing thresholds are similar in all subjects. All indices but Mini-mental scale of equastionnaire (MMSE) of patients and control group were not statistically different. There was no significant difference in pure tone audiometry (PTA), PTA2 (dB HL, mean +/- s) and WRS (%, mean +/- s) between the two groups (P > 0.05), therefore the hearing threshold of AD group (PTA = 26.3 +/- 8.5, PTA2 = 29.1 +/- 8.7, WRS = 85.5 +/- 15.5) is lower than that of control group (PTA = 23.2 +/- 10.6, PTA2 = 26.2 +/- 11.8, WRS = 87.6 +/- 16.8). No significant difference was found between the two groups in audiometry reliability, acoustic immittance and ABR (P < 0.05). CONCLUSION: No significant difference was found between the peripheral hearing dysfunction of AD patients and that normal elderly people, i.e., PTA, PTA2 and WRS were not related to MMSE.
