Observational StudyHypotensive anaesthesia and bleeding during endoscopic sinus surgery: an observational study.
Significant bleeding during functional endoscopic naso-sinusal surgery (FESS) impairs recognition of anatomical references and may negatively affect surgical outcome. Through their hypotensive effect, adjuvant anaesthetic agents may influence intraoperative bleeding. The present study compared intraoperative bleeding in patients undergoing FESS administered a clonidine-based anaesthetic regimen and in patients receiving other an anaesthetic combination with higher acquisition costs. ⋯ The anaesthetic combination including clonidine for controlled hypotensive anaesthesia produces lower levels of surgical field bleeding during FESS. Compared with other hypotensive anaesthetics, clonidine is inexpensive and associated with better surgical conditions during FESS. If confirmed through randomized clinical trials, the use of clonidine during FESS can reduce surgical time and improve surgical results through a less bloody field, resulting in lower patient morbidity and improvement of operating room resources.

Initial experiences with endoscopic rhino-neurosurgery in Amsterdam.
Endoscopic surgery of the skull base has been on the rise for several years. Endoscopic access for surgery can be achieved from the frontal sinus anteriorly along the skull base to the odontoid process posterior inferiorly. An endoscope is inserted through one nasal corridor and allows visualization of the working field and up to three surgical instruments can be used to address the lesion. ⋯ The most frequent complication was CSF leakage. This study demonstrates that this technique is safe and reliable. What is needed is a dedicated team, which includes a dedicated anesthesiologist, endocrinologist, ophthalmologist, and radiation oncologist.

The goal of the study was to find out the risk factors for the development of mediastinitis in patients with deep neck infections (DNI) and describe the differences in symptoms and clinical image between uncomplicated DNI and infections with mediastinal spread. Our study represents the retrospective analysis of 634 patients with DNI. The file was divided into two groups. ⋯ Due to our results, the predisposing factors for mediastinal extension of DNI are cardiovascular and pulmonary diseases. Mediastinitis is associated with higher morbidity and mortality than DNI. The most common complications are airway obstruction, pneumonia and sepsis.

Meta AnalysisMeta-analysis of clinical studies with betahistine in Ménière's disease and vestibular vertigo.
We present a meta-analysis of 12 double-blind, randomized, placebo-controlled clinical studies with betahistine in patients suffering from vestibular vertigo or Ménière's disease, based on both published and unpublished data. The clinical endpoint we used was the investigator's overall opinion on the response to treatment of the vertigo symptoms, after at least 1 month of treatment. We introduce a new effect parameter, the odds of a favorable treatment outcome, with the odds ratio as measure to compare the responses of betahistine and placebo patients. ⋯ Sub-analyses conducted for patients with Ménière's disease on one hand and with vestibular vertigo on the other hand also yielded statistically significant results. For Ménière's disease, the meta-analytical odds ratio was 3.37 (95% CI 2.14-5.29); for vestibular vertigo, the odds ratio was 2.23 (95% CI 1.20-4.14). Our meta-analysis supports the therapeutic benefit of betahistine on vertiginous symptoms in both Ménière's disease and vestibular vertigo.

ReviewInner ear damage following electric current and lightning injury: a literature review.
Audiovestibular sequelae of electrical injury, due to lightning or electric current, are probably much more common than indicated in literature. The aim of the study was to review the impact of electrical injury on the cochleovestibular system. Studies were identified through Medline, Embase, CINAHL and eMedicine databases. ⋯ The pathophysiology of cochleovestibular damage following electrical injury is unresolved. The mechanism of injury following lightning strike is likely to be quite different from that following domestic or industrial electrical injury. The formulation of an audiovestibular management protocol for patients who have suffered electrical injuries and systematic reporting of all such events is recommended.
