PurposeTo determine the outcomes of three different techniques of strabismus surgery in patients with convergence insufficiency intermittent exotropia (CI-X(T)).Patients and methodsSixty-seven patients with CI-X(T) with near-distance disparity (NDD) ≥10 prism diopter (PD) were included in this 1-year follow-up prospective study and were randomly divided into three groups: slanted bilateral LR recession (S-BLR) group in which 22 patients underwent bilateral slanting recession of the lateral rectus (LR) muscle, the I-RR group with 23 patients who underwent improved unilateral medial rectus (MR) resection and LR recession with the amounts of resection and recession biased to near and distance deviation, respectively, and the A-BLR group with 22 patients who underwent bilateral augmented LR recession based on the near deviation. A successful outcome at distant and near was defined as exodeviation between 10 PD of exophoria/tropia and 5 PD of esophoria/tropia. Cumulative probabilities of success, preoperative and postoperative distant, near deviations, and NDD among groups were analyzed and compared.ResultsThe success rate of distant exodeviation, near exodeviation, and NDD in the three groups after 1 year was statistically insignificant (P=0.054, 0.233, and 0.142, respectively). At the 1 year follow-up, vertical pattern strabismus (V and A patterns) was a feature of the S-BLR group, whereas the rate of postoperative overcorrection and undercorrection was significant in the A-BLR and I-RR groups, respectively.ConclusionThe success rate of correction of distant exodeviation, near exodeviation, and NDD was statistically indifferent among the three groups. However, each procedure has its specific postoperative concerns, which should be considered before implementing in patients with CI-X(T).

This study comprise the examination of 100 samples of feed(40), water (36) and litter (24) collected randomly from different chicken shops, houses and farms in Kafr El-Sheikh Governorate. Results of this survey revealed isolation of 14/100(14%) Salmonella species (3)(12.5%) isolates from litter, (5)(13.8%) isolates from water and (6)(25%) isolates from farms. The prevalence rate to Salmonella was (14%) Sensitivity test was made and isolates exhibit resistance against ciprofloxacin and cefotaxime with (89%) and highly sensitivity to amikacin with (100%) so amikacin is the first drug choice for treatment of Salmonella infection. A PCR based assay was developed to developed to detect the prevalence of Salmonella in samples and to evaluate plasmid and chromosome-borne virulence genes (stn-invA) which considered as a target genes for the detection of Salmonella The results of detection of resistance genes (qnr S-blaTEM) as a resistance genes in all isolates of Salmonella.
