Painful post-traumatic trigeminal neuropathy (PPTTN) is a distinctive facial pain syndrome characterized by facial and/or oral pain along the sensory distribution of the fifth cranial nerve with a clear history of a traumatic event. To our knowledge, PPTTN after endoscopic sinus surgery (ESS) has not been reported in the literature. We present a case of an elderly woman who experienced unilateral neuralgic pain after undergoing ESS. Following ESS of the left sphenoid sinus to remove suspicious fungus balls, the patient complained of intermittent facial pain occurring in the left periorbital and forehead area. Clinical diagnosis of PPTTN was established after a comprehensive multidisciplinary assessment. The pain disappeared completely after a 5-week medical treatment with gabapentin. Since PPTTN cases associated with ESS are extremely rare, our case demonstrates that PPTTN should be considered in the differential diagnosis of facial pain developing after ESS and can be successfully treated with medical therapy.

OBJECTIVE: To compare the slip reduction rate and clinical outcomes between unilateral conventional transforaminal lumbar interbody fusion (conventional TLIF) and unilateral minimal invasive TLIF (minimal TLIF) with pedicle screw fixation for treatment of one level low-grade symptomatic isthmic spondylolisthesis. METHODS: Between February 2008 and April 2012, 25 patients with low-grade isthmic spondylolisthesis underwent conventional TLIF (12 patients) and minimal TLIF (13 patients) in single university hospital by a single surgeon. Lateral radiographs of lumbar spine were taken 12 months after surgery to analyze the degree of slip reduction and the clinical outcome. All measurements were performed by a single observer. RESULTS: The demographic data between conventional TLIF and minimal TLIF were not different. Slip percentage was reduced from 15.00% to 8.33% in conventional TLIF, and from 14.15% to 9.62% in minimal TLIF. In both groups, slip percentage was significantly improved postoperatively (p=0.002), but no significant intergroup differences of slip percentage in preoperative and postoperative were found. The reduction rate also not different between conventional TLIF (45.41+/-28.80%) and minimal TLIF (32.91+/-32.12%, p=0.318). CONCLUSION: Conventional TLIF and minimal TLIF with pedicle screw fixation showed good slip reduction in patients with one level low-grade symptomatic isthmic spondylolisthesis. The slip percentage and reduction rate were similar in the conventional TLIF and minimal TLIF.

PURPOSE: Current resuscitation guideline recommends not using the automated external defibrillator (AED) in a running ambulance, because artifact arising from movement of the ambulance can interfere with rhythm analysis of AED and can simulate ventricular fibrillation (VF). This study was conducted to determine whether the AED can be operated correctly in a running ambulance. METHODS: Five AEDs were tested for their sensitivity, specificity, positive/negative predictive value, and accuracy. Each AED was connected to a manikin randomly simulating coarse and fine VF, asystole, and normal sinus rhythm, and each rhythm was analyzed 5 times by AEDs on the highway. Data about the shock recommendation given and delivery time interval from analysis to shock were collected. ECGs were also downloaded during the analysis time for a normal volunteer to search for baseline artifacts. RESULTS: All AEDs recommended shock delivery correctly for the simulated rhythms whether the ambulance was stopped (0 km/h) or running on unpaved road (20 km/h). The sensitivity, specificity, positive/negative predictive value, and accuracy of AEDs on the highway (100 km/h) were similar to those obtained in previous studies on AED performance in pre-hospital settings. The recorded ECG rhythm of a volunteer in a running car showed no baseline artifacts. CONCLUSION: All AEDs recommended shock delivery correctly in a running ambulance. Therefore, the current recommendation of not using the AED on a running ambulance should be reconsidered.

BACKGROUND: Patients who survive CPR are profoundly disabled and live with reduced quality of life. Therefore advanced directives are needed to ensure that life sustaining therapies are provided appropriately. This study compared the attitudes of elderly subjects toward advanced directives for CPR before and after receiving CPR education. METHODS: Between January and July 2007, 99 ambulatory persons aged older than 64 years were recruited from six community welfare facilities for the elderly. A questionnaire was distributed to obtain demographic data and their basic understanding and attitudes toward CPR. After providing information and showing a video clip on CPR, we compared whether having received this information influenced the thoughts of our subjects on CPR. RESULTS: None had had previous education on CPR, including prognostic information. Most overestimated the survival chance after CPR. Most wished to be resuscitated. After providing prognostic information on CPR and showing a short video clip, there was a change in their decision and the knowledge of CPR outcome seemed to influence their thoughts on CPR. In particular, the information on CPR prognosis greatly influenced their decision. CONCLUSION: Elderly people rarely have a chance to receive information regarding CPR. As a result, their decision to receive CPR may not accurately reflect the patient's wishes in emergency circumstances. It is important to pro- vide accurate prognostic information to help the elderly in their life-sustaining treatment decisions.

BACKGROUND: Recently, ultrasound has been commonly used. Ultrasound-guided interscalene brachial plexus block (IBPB) by posterior approach is more commonly used because anterior approach has been reported to have the risk of phrenic nerve injury. However, posterior approach also has the risk of causing nerve injury because there are risks of encountering dorsal scapular nerve (DSN) and long thoracic nerve (LTN). Therefore, the aim of this study was to evaluate the risk of encountering DSN and LTN during ultrasound-guided IBPB by posterior approach. METHODS: A total of 70 patients who were scheduled for shoulder surgery were enrolled in this study. After deciding insertion site with ultrasound, awake ultrasound-guided IBPB with nerve stimulator by posterior approach was performed. Incidence of muscle twitches (rhomboids, levator scapulae, and serratus anterior muscles) and current intensity immediately before muscle twitches disappeared were recorded. RESULTS: Of the total 70 cases, DSN was encountered in 44 cases (62.8%) and LTN was encountered in 15 cases (21.4%). Both nerves were encountered in 10 cases (14.3%). Neither was encountered in 21 cases (30.4%). The average current measured immediately before the disappearance of muscle twitches was 0.44 mA and 0.50 mA at DSN and LTN, respectively. CONCLUSIONS: Physicians should be cautious on the risk of injury related to the anatomical structures of nerves, including DSN and LTN, during ultrasound-guided IBPB by posterior approach. Nerve stimulator could be another option for a safer intervention. Moreover, if there is a motor response, it is recommended to select another way to secure better safety.

PURPOSE: National Emergency X-Radiography Utilization Study (NEXUS) criteria and the Canadian Cervical Spine rule (CCR) are commonly used in cervical trauma patients to determine whether a plain cervical X-ray should be performed. However, plain cervical X-rays are so inaccurate that cervical spine computed tomography (CT) is often considered as a screening test. We studied the usefulness of the NEXUS criteria and the CCR for determining the need for a CT evaluation in the emergency department (ED). METHODS: This prospective observational study was conducted from January 2007 to March 2008. Plain Xray and CT scans of the cervical spine were performed on blunt trauma patients with neck pain. The relevancy of CT was examined using the NEXUS criteria and the CCR. Sensitivity, specificity, positive predicted value, and negative predicted value analyses were performed to diagnose the cervical spine injury. RESULTS: During the study period, 284 patients were enrolled in this study. The sensitivity, specificity, positive predicted value, and negative predicted value of the NEXUS criteria were 87.5%, 1.1%, 5.0%, and 60.0% respectively, while those of the CCR were 87.5%, 8.2%, 5.3%, and 91.6%. There were two missed fracture cases when the NEXUS criteria and the CCR were applied independently, however, no cases were missed when both were applied. CONCLUSION: This study suggests the NEXUS and the CCR in combination can be used as a guide to CT evaluation for cervical spine injury in the ED.

A fungus ball is the most common manifestation of fungal sinusitis. Bilateral involvement of fungus balls is rare, and bilateral sphenoid involvement is even more uncommon. The authors report two cases of bilateral fungus balls with sphenoid sinus involvement successfully treated with endoscopic sinus surgery. Both patients complained of nonspecific headache; diagnoses were made with CT and histopathological examinations, and surgical removal was achieved via transostial approach. Bilateral fungus balls involving the sphenoid sinus are rare but do occur; their removal is possible through endoscopic sinus surgery with a high cure rate. We thus recommend using CT scanning to identify typical findings of a sphenoid fungus ball even in bilateral paranasal sinusitis and perform aggressive surgical treatment.

OBJECTIVE: To assess the significance of anti-type I collagen antibody titer in estimating cumulative trauma and predicting the presence of occupational low back pain. METHOD: Under the hypothesis that cumulative trauma on the spine will expose collagen and stimulate the formation of auto-antibody, we measured the serum anti-type I collagen antibody titers (IgM and IgG) in 408 male workers of a metal welding and manufacturing company. The antibody titers were measured in duplicates by ELISA. Statistical analysis was done to compare the titers according to occupational profiles (type of occupation and duration of employment) and clinical profiles (occurrence of low back pain, duration of low back pain and clinical impression). RESULTS: The anti-type I collagen IgG antibody titers were significantly increased in labor workers (n=357) in comparison with office workers (n=51)(p<0.05). Among the labor workers both IgM and IgG antibody titers were increased in the low back pain group (n=50) though it did not reach statistical significance (p-value of IgM antibody titers=0.07). IgM and IgG antibody titers were increased in the chronic low back pain group (> or =3 months)(n=8). CONCLUSION: These data suggest that anti-type I collagen IgM and IgG antibody may be useful in predicting the presence of occupational low back pain and estimating cumulative trauma, respectively.

Background: : Since primary emergency treatment should be performed appropriately and promptly, efficient and accurate communication between paramedics and medical staff is paramount to a successful primary emergency treatment and patient handover. The problem of the training program in Korea is that it concentrates more on in-class lectures, often delivered by non-medical specialists, who may lack in practical experience and without proper communication training. To solve this problem, we have devised a simulation based training that focuses on event debriefings and two-way communication. Methods: : 62 paramedics from 3 stations enrolled in the study. 4 different courses with different emergency situations were created and each course was taken twice resulting in a total of 8 classes. All courses were based on actual cases. The curriculum consisted of subject lectures with guidelines, skill practice courses, and simulation courses based on hands-on method. In simulation courses, paramedics use standardized check list to communicate with medical specialists. All curriculums except subject lectures include debriefing, which allows free talking with educators comprised of medical specialists. In order to measure the educational impact, all students performed self-assessment through a structured questionnaire before and after the training. Results: : Regardless different situations and paramedics’ education level, their performance and communication skills have improved after simulation training course. Paramedics mentioned learning skills in simulation course through communication with medical staffs as the biggest advantage. Conclusion : Receiving the simulation training with standardized communication tools is effective at enhancing the communication between the paramedics and medical staff.
