    Another BRIC on the web: the Brazilian presence in international agency statistical sites
    (2015-06-16) Colson, Harold
    Provides a brief recap of Brazilian statistical coverage in major and specialty international government organizations outside of Latin America, with a deeper report on the surprisingly strong set of Brazil data and economic analysis provided by the OECD (Organisation for Economic Co-operation and Development). The OECD covers "key partner" Brazil and other BRIC countries with special interest.

    Survey of endoscopic skull base surgery practice patterns among otolaryngologists
    (Wiley, 2018-04-16) Wannemuehler, Todd J.; Rabbani, Cyrus C.; Burgeson, Jack E.; Illing, Elisa A.; Walgama, Evan S.; Wu, Arthur W.; Ting, Jonathan Y.; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Background Endoscopic skull base surgery (ESBS) is a rapidly expanding field. Despite divergent reported preferences for reconstructive techniques and perioperative management, limited data exist regarding contemporary practice patterns among otolaryngologists performing ESBS. This study aims to elucidate current practice patterns, primarily the volumes of cases performed and secondarily a variety of other perioperative preferences. Methods An anonymous 32-item electronic survey examining perioperative ESBS preferences was distributed to the American Rhinologic Society membership. Statistical significance between variables was determined utilizing Student t, chi-square, and Fisher exact tests. Results Seventy otolaryngologists completed the survey. The effective response rate was approximately 22.5%. Sixty percent of respondents were in full-time academic practice and 70% had completed rhinology/skull base fellowships. Annually, 43.3 mean ESBS cases were performed (29.1 private practice vs. 52.9 academic practice, P = .009). Academic practice averaged 24.1 expanded cases versus only 11 in private practice (P = .01). Of respondents, 55.7% stood on the same side as the neurosurgeon and 72.9% remained present for the entire case. Current procedural terminology coding and antibiotic regimens were widely divergent; 31.4% never placed lumbar drains preoperatively, while 41.4% did so for anticipated high-flow cerebrospinal fluid leaks. While considerable variation in reconstructive techniques were noted, intradural defect repairs utilized vascularized flaps 86.3% of the time versus only 51.3% for extradural repairs (P < 0.001). Major complications were rare. Postoperative restrictions varied considerably, with most activity limitations between 2–8 weeks and positive airway pressure use for 2–6 weeks. Most respondents started saline irrigations 0–2 weeks postoperatively. Conclusions Based on responses from fellowship- and non-fellowship-trained otolaryngologists in various practice settings, there remains considerable variation in the perioperative management of patients undergoing ESBS.
