Study Selection: Inclusion criteria for qualitative FDA-approved Drug Library synthesis were a population of otosclerosis patients, intervention being primary stapes surgery

with a nickel titanium alloy (Nitinol) heat-crimping prosthesis, and hearing outcome. Inclusion criteria for quantitative analysis: application of audiometry guidelines of the American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium for evaluation of conductive hearing loss.

Data Extraction: Strategy and reporting based on Cochrane, Quality of Reporting of Meta-analyses, and Meta-analysis of Observational Studies in Epidemiology statements. A bias assessment tool was developed

according to Cochrane guidelines.

Data Synthesis: A quantitative synthesis was performed, but because of the heterogeneity in postoperative follow-up periods and outcome measures reported, we were not able to pool these data. A sample size analysis was performed to indicate the sample needed to demonstrate a statistically significant difference see more in hearing outcome between both interventions. Hearing outcome superiority of the Nitinol heat-crimping prosthesis over manually crimping prosthesis types was not demonstrated.

Conclusion: Superiority could probably not be demonstrated because of insufficient sample size. Research addressing technical improvements in stapes surgery should agree on a base sample size able to detect the smallest difference that is clinically important or accept the null hypothesis. With data gathered in the Common Otology Database as basis, a sample size of at least 413 patients is needed in both the intervention and the control group. Other clinical outcome measures also should be explored.”
“OBJECTIVE: The aim of this study was to determine the expression of fatty acid synthase (FASN) in oral nevi and melanomas, comparing the results with correspondent MK-0518 solubility dmso cutaneous lesions.

MATERIALS AND METHODS: Expression of FASN was evaluated by immunohistochemistry

in 51 oral melanocytic lesions, including 38 intramucosal nevi and 13 primary oral melanomas, in 10 cutaneous nevi and in 14 melanomas.

RESULTS: Fatty acid synthase was strongly expressed only in melanomas, either of the oral mucosa or cutaneous. On the other hand, most oral and cutaneous nevi were negative, with a few oral cases showing focal and weak expression.

CONCLUSION: Fatty acid synthase is expressed in malignant melanocytes, and it can be a helpful marker to distinguish oral melanomas from oral melanocytic nevi. Oral Diseases (2011) 17, 808-812″
“Objectives: To assess the association between clinical and socio-demographic features and anti-Parkinson drug (APD) treatment modifications in patients with PD and to describe neurologist and patient opinions regarding the need for changes in APD therapy.
