Abstract
INTRODUCTION Skull base reconstruction is one of the greatest challenges extended endonasal endoscopic surgery. Many grafts and flaps from the endonasal fossa have been demonstrated to be useful in the control of complications such a cerebrospinal fluid leaks. Review and analysis of these resources are necessary in skull base recontruction to improve outcomes. OBJECTIVES The target is to create a consensus document on the use of different endonasal flaps and grafts in the skull base surgery. MATERIAL AND METHODS Literature review of the most relevant free grafts and vascularized flaps from the endonasal fossa. Analysis using the Delphi method on the use of the different endonasal resources for endoscopic repair of skull base defects. RESULTS We obtained two results: 1) A selection of the most representative flaps and grafts from the endonasal fossa, describing origin, surface and indications, based on a literature review. 2) A consensus document, using Delphi methodology, with general considerations (2), recommendations (10) and limitations (6) of the different endonasal flaps and grafts. CONCLUSIONS We present the first consensus document in the field of extended endonasal endoscopic surgery using the Delphi method as a working tool. We highlight the usefulness of the nasoseptal flap together with other endonasal flaps and grafts for skull base reconstruction.

Abstract
This report introduces a new closure technique for the management of intraoperative cerebrospinal fluid (CSF) leakage during endoscopic endonasal surgery. The procedure is based on the combination of a traditional autologous tissue flap with a heterologous fibrin graft (TachoSil). We performed a retrospective analysis on 121 patients with pituitary adenomas treated in our center by the senior neurosurgeon (author V.R.B) in the previous 4 years. Only one patient (0.8%) developed a CSF leakage and no adverse events were found related to the use of TachoSil. Compared with other techniques used previously, sellar diaphragm reconstruction with TachoSil seems to be an effective and inexpensive alternative.

Abstract
INTRODUCTION To design and validate a simulator for learning and training in the capsulorhexis technique. METHODS The system consists of a methacrylate support inclined 15° for the surgeon's hand, an area of commercially available aluminum foil, and another one of similar characteristics, where the student performs the technique through some slots that are previously made in the support. In order to evaluate the feasibility of this simulator, data were collected from 65 ophthalmologists performing the technique during training activities. The ophthalmologists were randomly divided into one group of 30 specialists who start their learning on the eyes of an animal cadaver, and into another of 35 specialists who previously started with this simulator. RESULTS A simulator is developed for training in the capsulorhexis technique. The students from the simulator group achieved a reduction in the use of cadaver eyes, and a higher efficiency in correct capsulorhexis, unlike the group who started directly on the cadaver eyes. CONCLUSIONS This simulator is an innovation in training of the capsulorhexis technique as regards simplicity, cost, and reuse, as compared to other virtual simulators with more expensive computer equipment (CE) equipment that are more difficult to transport. It is an important step prior to the use of cadaver parts and experimental animals, decreasing the number of both, and therefore the teaching costs.

Abstract
Telomerase is a ribonucleoprotein DNA polymerase that has been associated with cell proliferation, cell survival and apoptosis inhibition. Telomerase is regulated by specific growth factors, cytokines and hormones. The present study examines the effect of GH on telomerase activity and identifies the signal transduction pathway involved in this process in Chinese hamster ovary (CHO)4 cells, which express rat GH receptor cDNA. Telomeric repeat amplification protocol assays demonstrated that treating CHO4 cells with increasingly high doses of GH up-regulated telomerase activity with the maximum activation at 24 h. Similarly, GH activated telomerase in another cell system, primary cultures of rat hepatocytes. The telomerase activation in CHO4 cells was produced with an increase in hamster telomerase catalytic subunit (hamTERT) mRNA expression. The telomerase activity induced by GH was specifically blocked by the phosphatidylinositol 3'-kinase (PI3-K) inhibitor, LY294002, but not by the MAP kinase kinase inhibitor, PD98059. These findings suggest that GH could activate telomerase through the direct activation of TERT transcription, as well as through the PI3-K signalling pathway.
