0 diopters (D) to 30.0 D. The AFM analysis was performed in contact mode using a V-shaped silicon nitride cantilever with a pyramidal tip curvature of 15 nm and a nominal spring constant of 0.2 N/m. Detailed surface characterization of the IOL optic was obtained using 6 quantitative parameters provided by the AFM software.\n\nRESULTS: Five of 6 roughness parameters indicated statistically significant differences (P<.05) between IOLs with different dioptric powers, with the 100 D IOL

in both models providing the smoothest optic surface. Between models Momelotinib research buy with the same dioptric power, the SN60AT model had lower values of each surface roughness parameter than the SA30AL model.\n\nCONCLUSIONS: Atomic force microscopy was an accurate tool for assessing the surface properties of IOL optics. Manufacturing processes were responsible Entinostat mw for introducing detectable differences in the topography of IOL biomaterials with identical copolymer constituents but different dioptric powers Nanometric analysis may assist IOL manufacturers in developing IOLs with optimal surface characteristics.

“Objective: To investigate whether there is a relationship between gastroesophageal reflux disease (GERD) and recurrent acute otitis media (RAOM)

in infants and children. Possible risk factors are also explored.\n\nMaterial and methods: 221 consecutive children who had symptoms and signs associated with GERD and had undergone a prolonged ambulatory 24-h esophageal pH-monitoring. Thirty-four children were excluded from the study due to age, neurological deficits, congenital abnormalities, immunodeficiency syndromes

or other chronic systemic disorders. The remaining 187 children (96 boys and 91 girls), aged between 40 days and 33 months (mean age of 18.3 months) were assigned into three groups according NU7441 manufacturer to their Reflux Index (RI%). Group A: 49 children (26.2%) without GERD (control group); Group B: 78 children (41.7%) with low to moderate RI; and Group C: 60 children (32.1%) with severe GERD. Parental interviews and personal medical files of the National Health System were used for data collection. However, episodes of acute otitis media were taken into account only if they were diagnosed by a physician. The follow-up period ranged from 6 to 8 years in order to cover the peaks of otitis media incidence in childhood.\n\nResults: The results revealed that 6 children from Group A (12.24%), 11 from Group B (14.1%) and 19 from Group C (31.67%) presented episodes of RAOM. The difference was statistically significant (p = 0.01). Furthermore, in children who received anti-reflux treatment, the incidence of RAOM substantially decreased and eventually became approximate to that of the control Group A (12.32%).
