Encircling narrow band versus buckle for retinal detachments with intrabasal or unseen retinal breaks

Purpose: To compare the results of narrow encircling band surgery with standard encircling scleral buckling for retinal detachments (RDs) with intrabasal or unseen breaks. Methods: In a retrospective study, eyes with intrabasal or unseen breaks underwent narrow band implantation (group N) or standard encircling buckling plus wide tire placement (group W) and were followed for at least one year. Results: A total of 112 eyes including 39 eyes in group N and 73 eyes in group W were studied. Preoperatively visual acuity of eyes in group N was significantly better (1.55 ± 0.9 vs. 1.93 ± 0.9 logMAR, P = 0.043). The two study groups (N and W) were comparable in terms of the extent of RD (2.8 ± 0.96 vs. 2.8 ± 0.93 quadrants), interval to surgery (88.3 ± 176.4 vs. 71.9 ± 135.4 days) and percentage of visible breaks (56.4% vs. 63%), respectively (all P values > 0.05). More atrophic holes were present in group W and more dialyses were reported in group N. The single operation success rate at 12 months was 69.2% in group N and 74% in group W (P = 0.1). The single operation success rate for eyes with unseen breaks was also comparable (66.7% vs. 85.7%, P = 0.157). Final corrected visual acuity was also similar (0.63 ± 0.44 vs. 0.85 ± 0.69 log MAR). The only factor influencing success rate was the type of retinal breaks (P = 0.04). Type of scleral buckling did not affect the single operation success rate (P = 0.460). Conclusion: Narrow encircling band surgery is a possible option with acceptable single operation success rate for RDs with intrabasal or unseen breaks

 </style> <![endif]--> <p>PURPOSE: To compare the anatomical and visual outcomes of three different scleral buckling techniques and to explore the effect of cryotherapy and subretinal fluid drainage (SRFD) on outcomes of surgery. METHODS: This retrospective study was performed on 111 eyes of 109 patients undergoing scleral buckling for rhegmatogenous retinal detachments (RRDs) by a single surgeon. Pre-, intra- and postoperative data were retrieved from hospital records. RESULTS: Buckles were radial in 27 (24.3%), circumferential (segmental) in 16 (14.4%) and encircling in 68 (61.3%) eyes. Anatomical and visual results were comparable with all three buckling techniques. Application of cryotherapy, the spot number, and SRFD did not affect anatomical and visual results. The only preoperative factor associated with poorer anatomical results was the presence of multiple retinal breaks (P=0.006). The following preoperative factors affected visual outcomes on univariate analysis: extent of retinal detachment (r=0.417, P=0.011) and relative afferent pupillary defect (r=0.423, P=0.02). Preoperative macular status (attached vs detached) also had a significant effect on visual outcomes (P < 0.001). Based on multivariate analysis however, only preoperative macular status was significantly correlated with visual results (P=0.022). Silicone sponges placed for non-encircling surgery were removed due to ocular dysmotility in 4 (3.6%) eyes, cosmetic reasons in 3 (2.7%) cases and extrusion in 2 (1.8%) eyes. One encircling tire was also removed due to extrusion. CONCLUSION: Surgical technique and performing cryotherapy or SRFD do not seem to influence the anatomical and visual outcomes of scleral buckling. Postoperative complications seem to be more prevalent with non-encircling techniques.</p> <!--[if gte mso 9]><xml> Normal 0 false false false MicrosoftInternetExplorer4 </xml><![endif]--><!--[if gte mso 9]><xml> </xml><![endif]--> <!--[if gte mso 10]> <style>

Medical Waste Management in the second largest City of Iran (Mashhad) with Three-Million Inhabitants

Introduction: One of the first and important steps to improve medical waste management is awareness and monitoring of the quality and quantity of medical waste. The aim of this study was to determine the present status of waste generation and the process of waste management in hospitals. Materials and Methods:This cross sectional study was performed in ten university hospitals in Mashhad. A standard questionnaire was prepared according to the National Health instructions and completed by the project team members who were environmental health experts.  Results: The total waste which was generated in the studied hospitals was 7683 kg/day. The study showed total waste generation in selected hospitals as (61.85%) general medical waste, (34.90%) infectious waste and (3.25%) sharp waste. The average generation rate for total, general, infectious and sharp waste was (2.6, 1.5, 1.01) and (0.08) kg/bed/day, respectively. Mean scores of the different steps of waste management process with respect to National Health instructions were as follows: waste segregation (64%), waste storage (67%), waste transportation (76 %) and waste treatment 63%. There was no significant difference between the average rate of waste generation per bed in public and specialized hospitals (P=0.34). Conclusion: High rate of infectious waste shows the need for establishing executive rules and standards for medical waste management. Medical managers should update their knowledge and further educating their staff; implying careful and constant monitoring of waste management
