Anatomical success rate of macular hole surgery with autologous platelet without internal-limiting membrane peeling.

AIM: To describe our experience and success rate of macular hole surgery with pars plana vitrectomy with autologous platelet and without internal limiting membrane peel. METHODS: Retrospective review of 56 consecutive patients who underwent macular hole surgery. RESULTS: Anatomical success was achieved in 55 out of 56 patients (98.2%). Functional success was achieved in 37 out of 56 patients (66.1%). A total of 21 patients (37.5%) achieved postoperative visual acuity of 6/12 or better. No intraoperative complications were encountered. Postoperative complications included cataract progression in eight eyes and raised intraocular pressure in 20 eyes. CONCLUSIONS: Our success rate was comparable to that reported in macular hole surgery incorporating internal limiting membrane (ILM) peel or with autologous platelet without ILM peel.

An in vitro Flaviviridae replicase system capable of authentic RNA replication.

We have established an in vitro replication system for bovine viral diarrhea virus (BVDV), a surrogate for the closely-related hepatitis C virus. In an in vitro reaction, BVDV replication complexes synthesize vRNA and replicative form (RF) and replicative intermediate (RI) RNAs. Kinetic and heparin trapping experiments demonstrate the recycling of RF and RI products and the initiation of vRNA synthesis in this system. Consistent with this, quantitative hybridization reveals the asymmetric synthesis of positive and negative strand RNA products. These findings support the notion that RF serves as a template and RI as a precursor in the synthesis of vRNA. Furthermore, the antiviral activity of an NS5B inhibitor was similar in BVDV replicase and infectivity assays. Together, these results indicate that the in vitro activity of BVDV replicase complexes recapitulates RNA replication that occurs in infected cells, providing a system in which to study both mechanisms and inhibitors of Flaviviridae replication.
