On rare occasions, sudden hearing loss may be associated with a migraine. To our knowledge, there have only been two prior reports of sudden hearing loss attributed to migraines. A 40 years old man had suffered from recurrent headaches with hemiparesis, vertigo, and hearing loss for the past three years. At this time, he presented with severe bilateral sensorineural hearing loss of sudden onset, anarthria, right hemiplegia, tinnitus, and vertigo. An audiogram showed a down-sloping sensorineural hearing loss of 77dB by pure tone average on the right side and 72dB on the left. Sixteen days later, audiographic findings improved to 30dB of pure tone average on both sides. Vasospasm of the labyrinthine arteries instigated by migraine might explain these inner ear symptoms. A history of migraine should be sought in patients with sudden hearing loss and when found, anti-migraine medications such as calcium channel block-ers should be considered.

PURPOSE: This research investigated the extent of telephone advisers'satisfaction with respect for giving telephone advice and the working environment at 12 emergency medical information centers. METHODS: During July 2004, we approached 12 emergency medical information centers. We sent a three page postal questionnaire to each worker. The questionnaire had three parts questions about the working environment, giving telephone advice, and demographic characteristics. RESULTS: The response rate was 81.8%. The hundred (100) workers selected for this study were telephone advisers. As to the working environment, they were unsatisfied with the small workspace and the poor ventilation. Sixty-three (63) workers had telephone advice education. They felt that 'callers' overstatements' and 'not seeing the patients' left them stressed when giving telephone advice. They anticipated that 'protocol' and 'education about medical knowledge' were necessary for improving telephone advice. Seventy-three (73) workers had experienced burnout syndrome. CONCLUSION: Based on this survey on the extent of satisfaction with giving telephone advice and with the working environment, we think that improvements in the working environment and in the professional education for telephoneadvice skills are necessary. Also, we suggest that education to improve advisers'medical knowledge, development of advice protocols, and a program to prevent and manage burnout syndrome are required for enhanced work satisfaction in the future.

PURPOSE: Standard chest compression is useful for cardiopulmonary resuscitation of victims but may be difficult to perform in a confined space if the victim is lying on his side. The aim of this study was to evaluate compression techniques administered to individuals lying in various alternative positions, and to determine which ones may be easier to perform in such situations. METHODS: Thirty two volunteers trained in basic life support (BLS) were enrolled. They were taught to do compression in four alternative positions (over-head position (OHP), saddle position (SP), upper diagonal position (UDP) and lower diagonal position (LDP)). For each position, they performed two minutes of continuous chest compression on a manikin that was connected to a Laerdal PC Skill Reporting System. They did this for the basic standard position (BSP) and four alternative positions with the positions presented randomly. The data, including the total number of compressions, the average rate of chest compressions per minute, the depth of each chest compression, and the position of the hands were recorded and analysed. RESULTS: There were no statistically significant differences between BSP and alternative positions for the total number of compressions (BSP:108.8 min-1; OHP:109.5 min-1; SP:107.8 min-1; UDP:108.5 min-1; LDP:107.7 min-1) of chest compressions. There was no statistically significant difference between BSP and alternative positions for the average depth of each compression (BSP:41.9 mm; OHP:44.4 mm; SP:41.8 mm; UDP:42.9 mm; LDP:41.1 mm), or for the number of incorrect hand positions except UDP (BSP versus UDP = 6.4 versus 32.5). p<0.054 is not normally considered significant. The p value has to be 0.050 or smaller. CONCLUSION: Chest compression in alternative positions can be equally effective as it is in the standard position. If chest compression in the standard position is not easily executable in a confined space, chest compression using an alternative positions can be used.
