Evaluation of vestibulo-ocular reflex in patients with damage to the central nervous system (GCS score 5-3).

PURPOSE: The aim of our study was to evaluate the vestibulo-ocular reflex (VOR) in patients with severe damage to the central nervous system (CNS) in the diagnosis of brain death and survival prognosis. MATERIAL AND METHODS: The study was conducted in 20 patients with extensive primary central nervous system damage against spontaneous intracranial haemorrhage or craniocerebral trauma and secondary central nervous system damage as a result of cardiac arrest with Glasgow Coma Scale (GCS) score from 3 to 5 treated in the Intensive Care Unit, University Hospital in Bialystok. For labyrinth stimulation we used water at 30°C, recording the reactions with ENG appliance. Records were analyzed in Nathanson-Bergman four-level scale. The first assessment was performed on the second day after the trauma and subsequently the assessments were repeated at 2-day intervals. RESULTS: Of the 20 patients studied, the reflex was recorded in nine, which accounted for 45%. In the remaining 11 (55%) patients the reflex was not reported in any test and all of them died. Among patients with recorded VOR, five died and four survived. CONCLUSIONS: The results of our study show the usefulness of performing the vestibulo-ocular test in patients with severe brain injury to predict their survival.

Palliative embolization of hemorrhages in extensive head and neck tumors.

BACKGROUND: A lot has changed in terms of intervention technique, indications and embolic agents since Duggan introduced embolization to management of postraumatic epistaxis in 1970. Embolization is used in treatment of spontaneous and traumatic epistaxis, palliative tumors and vascular defects, as well as vascularized tumors and juvenile nasopharyngeal angiofibromas. The possibility of simultaneous visualization of pathology and implementation of therapy is one of its greatest advantages. MATERIAL/METHODS: Authors analyzed the efficacy of selective embolization treatment of haemorrhage in advanced head and neck tumors. Seventy-six patients with such tumors treated at the Department of Otolaryngology in Bialystok between1999 and 2011 were examined. RESULTS: Embolization of bleeding vessel within the tumor was effective (hemorrhage was stopped) in 65 patients (86%). Although the method is highly efficient, it is still associated with complications. Fourteen patients suffered from headaches that lasted for several days and six from face edema. Rebleeding was rare. Unfortunately, there was one case of hemiparesis. CONCLUSIONS: We conclude that superselective endovascular treatment deserves to be considered alongside standard options for the palliative or preoperative management of acute hemorrhage from advanced head and neck cancers.
