"Whiplash"-type injuries are commonly encountered and often cause neck pain, neck stiffness, and headaches. However, these injuries can have rare and poorly recognized complications, such as the development of a prevertebral hematoma leading to acute respiratory failure in the emergency department, followed by severe, life-threatening dysphagia and recurrent aspirations. In the patient described herein, a whiplash injury was accompanied by vocal cord paralysis and dysphonia (vagus nerve), dysgeusia (glossopharyngeal nerve, vagus nerve), and upper esophageal spasm (cricopharyngeal muscle, vagus nerve). It is unlikely that this was a complication of cervical fusion surgery. Instead, a combined stretch-induced lower cranial nerve injury, possibly on the exit of these nerves through the jugular foramen, seems to be a likely, but underappreciated mechanism occurring in rare instances of whiplash injuries.

Plexiform neurofibroma is a rare benign tumor and a special subtype of neurofibromatosis 1. This report is a literature review with a case of patient with facial hemorrhage observed at the site of neurofibroma removal in the right lower face due to minor trauma. Through PubMed search, using terms ((facial hematoma) OR (facial bleeding)) AND (neurofibromatosis), 86 articles were identified, and five related articles (six patients) were finally selected. Of the six patients, two had previously undergone embolization. However, as a result, all patients received open surgery to remove hematomas. The hemostatic methods mentioned were vascular ligation (five patients), hypotensive anesthesia (two patients), and postoperative blood transfusion (four patients). In conclusion, spontaneous or minimally traumatic bleeding is possible in neurofibromatosis patients. In most cases, it can be resolved by vascular ligation under hypotensive anesthesia. Optionally, prior embolization and supplementary tissue adhesive may be used.

Purpose: For determining the prognosis of critically injured patients, transporting patients to medical facilities capable of providing proper assessment and management, running rapid assessment and making rapid decisions, and providing aggressive resuscitation is vital. Considering the high mortality and morbidity rates in critically injured patients, various studies have been conducted in efforts to reduce those rates. However, studies related to diagnostic factors for predicting severity in critically injured patients are still lacking. Furthermore, patients showing stable vital signs and alert mental status, who are injured via a severe trauma mechanism, may be at a risk of not receiving rapid assessment and management. Thus, this study investigates diagnostic factors, including physical examination and laboratory results, that may help predict severity in trauma patients injured via a severe trauma mechanism, but showing stable vital signs. Methods: From March 2010 to December 2011, all trauma patients who fit into a diagnostic category that activated a major trauma team in CHA Bundang Medical Center were analyzed retrospectively. The retrospective analysis was based on prospective medical records completed at the time of arrival in the emergency department and on sequential laboratory test results. PASW statistics 18(SPSS Inc., Chicago, IL, USA) was used for the statistical analysis. Patients with relatively stable vital signs and alert mental status were selected based on a revised trauma score of more than 7 points. The final diagnosis of major trauma was made based on an injury severity score of greater than 16 points. Diagnostic variables include systolic blood pressure and respiratory rate, glasgow coma scale, initial result from focused abdominal sonography for trauma, and laboratory results from blood tests and urine analyses. To confirm the true significance of the measured values, we applied the Kolmogorov-Smirnov one sample test and the Shapiro-Wilk test. When significance was confirmed, the Student's t-test was used for comparison; when significance was not confirmed, the Mann-Whitney u-test was used. The results of focused abdominal sonography for trauma (FAST) and factors of urine analysis were analyzed using the Chi-square test or Fisher's exact test. Variables with statistical significance were selected as prognostics factors, and they were analyzed using a multivariate logistics regression model. Results: A total of 269 patients activated the major trauma team. Excluding 91 patients who scored a revised trauma score of less than 7 points, 178 patients were subdivided by injury severity score to determine the final major trauma patients. Twenty-one(21) patients from 106 major trauma patients and 9 patients from 72 minor trauma patients were also excluded due to missing medical records or untested blood and urine analysis. The investigated variables with p-values less than 0.05 include the glasgow coma scale, respiratory rate, white blood cell count (WBC), serum AST and ALT, serum creatinine, blood in spot urine, and protein in spot urine. These variables could, thus, be prognostic factors in major trauma patients. A multivariate logistics regression analysis on those 8 variables showed the respiratory rate (p=0.034), WBC (p=0.005) and blood in spot urine (p=0.041) to be independent prognostic factors for predicting the clinical course of major trauma patients. Conclusion: In trauma patients injured via a severe trauma mechanism, but showing stable vital signs and alert mental status, the respiratory rate, WBC count and blood in the urine can be used as predictable factors for severity. Using those laboratory results, rapid assessment of major trauma patients may shorten the time to diagnosis and the time for management.

Objective : An apparent increase of use of drugs affecting hemostasis in our neurosurgical department since the 1990s has encouraged us to investigate whether these drugs influence the clinical course and results of surgery for chronic subdural hematoma (CSDH). Methods : This retrospective analysis included 178 patients admitted for CSDH from 2007 to 2011 who were divided into two groups : on drugs affecting hemostasis (40; 22%) and no bleeding disorders (138; 78%). Medications in the first group included oral anticoagulants (33; 82.5%), antiplatelets (5; 12.5%) and low molecular weight heparins (2; 5%). Results : The patients on drugs affecting hemostasis were older ($74.3{\pm}7.4$ vs. $68.4{\pm}14.8$; p-value 0.01) and the group without bleeding disorders had more head trauma history (61% vs. 38%, p-value 0.01). The groups did not differ in bilateral hematoma rates (25% vs. 20%, p-value=NS). At diagnosis, mean hematoma thickness was lower in patients on drugs affecting hemostasis ($18.7{\pm}7.4mm$ vs. $21.9{\pm}7.9mm$, p-value<0.01). Average stay of hospital was 1 day longer in patients on drugs affecting hemostasis ($11.7{\pm}4.1$ vs.$10.9{\pm}5.3$, p-value=NS) and was related to the necessity of bleeding disorder reversal. Mean neurological status at presentation was similar between the groups (p-value=NS) as was the likelihood of hematoma recurrence (p-value=NS). Glasgow Outcome Scale results were comparable. Conclusion : Patients on drugs affecting hemostasis are less often aware of a head trauma history, possibly suggesting a higher CSDH risk after minor trauma in this group. In these patients, smaller hematomas are symptomatic, probably due to faster hematoma formation. Drugs affecting hemostasis do not affect treatment results.

Purpose: To evaluate interpretation errors involving spine MRIs by residents in their second to fourth year of training, classified as minor, intermediate and major discrepancies, as well as the types of commonly discordant lesions with or without clinical significance. Materials and Methods: A staff radiologist evaluated both preliminary and final reports of 582 spine MRIs performed in the emergency room from March 2011 to February 2013, involving (1) the incidence of report discrepancy, classified as minor if there was sufficient description of the main MR findings without ancillary or incidental lesions not influencing the main diagnosis, treatment, or patients' clinical course; intermediate if the correct diagnosis was made with insufficient or inadequate explanation, potentially influencing treatment or clinical course; and major if the discrepancy affected the main diagnosis; and (2) the common causes of discrepancy. We analyzed the differences in the incidence of discrepancy with respect to the training years of residents, age and sex of patients. Results: Interpretation discrepancy occurred in 229 of the 582 cases (229/582, 39.3%), including 146 minor (146/582, 25.1%), 40 intermediate (40/582, 6.9%), and 43 major cases (43/582, 7.4%). The common causes of major discrepancy were: over-diagnosis of fracture (n = 10), missed cord lesion (n = 9), missed signal abnormalities associated with diffuse marrow (n = 5), and failure to provide differential diagnosis of focal abnormal marrow signal intensity (n = 5). No significant difference was found in the incidence of minor, intermediate, and major discrepancies according to the levels of residency, patients' age or sex. Conclusion: A 7.4% rate of major discrepancies was found in preliminary reporting of emergency MRIs of spine interpreted by radiology residents, probably related to a relative lack of clinical experience, indicating the need for additional training, especially involving spine trauma, spinal cord and bone marrow lesions.

Empyema thoracis following pneumonia, pulmonary tuberculosis, trauma and surgical procedures continues to be a source of major morbidity and mortality. We retrospectively reviewed the hospital records of 330 patients [child:87, adult243] treated for empyema thoracis at Catholic Medical Center between 1964 and 1986. The causes of empyema in these patients were as follows: pneumonia [C***:66%, A***:30%], pulmonary tuberculosis [C:2%, A:20%], lung abscess [C:3%, A:5%], postoperative complication [C:0%, A:13%], trauma [C:1%, A:4%] and unknown origin [C:23%, A:17%]. Three patients in this series died of sepsis from necrotizing pneumonia. Staphylococcus [29.3%], Streptococcus [8.8%], E. coli [8%], Mycobacterium tuberculosis [7.9%], Klebsiella [7.4%], Pseudomonas [6.4%], Bacteroides [3.4%] were the organisms most commonly isolated. Bacterial isolates were single in 68.3%, multiple 7.5% and absent 24.2%. The type of organism did not correlate with severity of disease or eventual requirement for closed thoracotomy drainage, open thoracotomy drainage [Modified Eloesser*s procedure], thoracoplasty, decortication or pleuropneumonectomy. Successful methods of treatment included aspiration in 44%, tube thoracotomy in 66%, open thoracotomy drainage in 98.7%, thoracoplasty in 98%, decortication in 96% and pleuropneumonectomy in 73%. Initial mode of management in empyema thoracis are thoracentesis and closed thoracotomy drainage. If the initial management was failed, we performed another surgical procedures. Before 1973, we manage with Schede`s thoracoplasty in the postpneumonectomy empyema patients. But thoracoplasty, with or without the use of muscle flaps, is a hazardous operation in the poor-risk patients. The permanent, open thoracotomy drainage is a relatively minor operation which is well tolerated even by cachexic, septic patients. It controls infection, and sometimes results in the bronchopleural fistula closing spontaneously.

Purpose: To evaluate the precipitating factors of amputation as initial treatment in diabetic foot patients. Materials and Methods: Between March, 1994 and February 2003, 41 cases (37 patients) diabetic foot patients who had diabetic ulcer, pyogenic inflammation and gangrene and followed up over 1 year were collected. Among them, We evaluate the precipitating factors of amputation for average 39.6months (12-118months). Results: Among many factors, Wagner classification, pulse volume recording of toes, Ankle-Brachial Index and Albumin level are statistically significant in amputation patients. Conclusion: In determining the amputation of diabetic foot as initial treatment, the trauma history, circulation of foot and serum albumin level are important precipitating factors. So the education about preventing even minor trauma and maintaining good nutrition state decrease the amputation rate in diabetic foot patients.
