Yemeni experience with phacoemulsification

To evaluate the first experience of phacoemulsification in Yemen from 2000-2007 regarding the visual results, and complications. Two hundred and fifty-eight eyes of 182 adult patients with significant cataract were included during the last 96 months. All eyes underwent phacoemulsification with implantation of intraocular lenses. The results were recorded and statistically analyzed. The male:female ratio was 1:1, with an average age of 52 years. Phacoemulsification was carried out by scleral approach in 14 eyes, and by clear corneal approach in 244 eyes. A visual acuity of >/= 6/18 was achieved in 85.3%, and the most common serious complication was intraoperative posterior capsule rupture, which was reported in approximately 10.1%. The results of phacoemulsification are very impressive, and the most common intraoperative complication was ruptured posterior capsule

Effects of two types of composite resin on oral bacterial plaque In vitro qualitative and quantitative study

160 specimens of composite [80 chemical and 80 light cured] were prepared in teflon mold 4 mmx 2.5mm in dimension. Plaque samples were collected using absorbent paper points from 20 normal persons and 20 persons with cervical carious teeth. The samples were inoculated in TSB containing both types of composites. Duplicate cultures were done for aerobic and anaerobic incubations at 37°C. There was no effect of both types of composite on the quality of the isolated organisms from normal group or patient group. Chemical and light cured composite increased significantly the count of aerobic bacterial plaque from normal group. While they decreased the count of aerobic bacterial plaque from patient group and also the anaerobic bacterial plaque from both normal and patient group
