In this study, we analyzed extrusion rates and adverse effects of fluoroplastic, titanium, and gold ventilation tubes of different sizes in adult patients with Meniere’s disease.

Methods: Clinical record study including 108 patients.

Results: Otorrhea occurred in 18% of fluoroplastic tubes but only 4% of titanium tubes. Permanent occlusion was observed in 22% of fluorplastic but only 4% of titanium tubes. check details No statistical difference was seen for transient dysfunction and tube extrusion rates. Granulations and chronic perforations were not observed.

Discussion: The low rate of infections and permanent occlusions

for titanium tubes as well as the lack of granulations and chronic perforations for all tubes might be due to the fact that our patients were adults with healthy middle ears. Furthermore, a better biocompatibility of titanium in the middle ear compared with gold or synthetic materials has been observed for protheses used to rebuild the sound conductive apparatus of the middle ear.

Conclusion: Titanium tubes might be the better choice for adult patients lacking Eustachian tube dysfunction and otitis media with effusion. Ventilation tubes in adults with healthy middle ears seem to be less associated with adverse

effects PFTα nmr compared with ventilation tubes in children with otitis media with effusion or recurrent otitis media.”
“Naproxen (NPX)-loaded poly-(D,L-lactic-co-glycolic acid) (PLGA) microparticles were prepared by the emulsion-solvent

evaporation method. The different organic solvents used significantly affects the properties of the microparticles obtained. These microparticles exhibited a controlled release profile that extends up to 15 days depending on the organic solvent used. The formulations did not exhibit zero-or first-order release kinetics and no agreement with Higuchi or Korsmeyer-Peppas models was obtained. In all cases, the dissolution profiles were fitted to the model proposed by Gallagher and Corrigan for PLGA systems. It was found that this model fully describes the dissolution processes. An interesting relationship between the NPX solubility in the AZD6094 inhibitor organic solvents studied and some parameters obtained for the dissolution model of the microparticles prepared with the same solvents is thus obtained. Accordingly, it can be proposed that the drug solubility in organic solvents is relevant to estimate the physical characteristics of microparticles other than its dissolution profiles.”
