BACKGROUND: Sometimes digoxin may be needed to be administered during anesthesia for the control of the ventricular rate and mitigation of lung congestion. For the lack of studies in surgical patients we wanted to determine digoxin pharmacokinetics (PK) in subjects undergoing a gastrectomy under enflurane anesthesia. METHODS: Over 72 hours, 16 serum samples from each of 14 subjects (ASA status 1 or 2) diagnosed with gastric cancer were collected after a single intravenous dose of digoxin 10ng/kg actual body weight for serum concentration measurements by fluorescence polarization immunoassay. Digoxin was injected 30 minutes after beginning surgery. Two, three and non-compartmental (TwC, ThC and NC, respectively) PK parameters were determined using WinNonln. The important parameters (AUC, Cl, Vss, t beta 1/2 [elimination half-life], Vc, MRT) of 3 PK's were statistically evaluated about which compartment PK was appropriate to the data here. The parameters of TwC PK of the surgical subjects were compared to those of nonsurgical ones which had already been published by other investigators. The postoperative outcomes (ambulation date, diet date, discharge date, complications, APACHE II and MOF [multiple organ failure]) in 19 patients (nondigoxin group) not treated with digoxin were compared with 19 patients (digoxin group) treated with digoxin 5ng/kg two times at 2 hour intervals during surgery. RESULTS: No significant differences were found in parameters between TwC and NC. Significant differences were observed in parameters of PK between ThC versus Twc and NC (P < 0.01). Cl and Vss of surgical subjects were larger than those of nonsurgical ones, and t beta 1/2 was similar. No significant effect of digoxin on postoperative outcomes was demonstrated. CONCLUSIONS: The dosage of digoxin for surgical patients should be titrated to the bleeding amount and the severity of surgical trauma because of larger Cl and Vss. The effect of digoxin on postoperative outcomes remains to be studied.

Subcutaneous emphysema and pneumomediastinum are commonly derived from trauma or injury of respiratory or gastrointestinal tracts, but occasionally the origin of air was not determined at evaluation. We report on a case of severe subcutaneous emphysema detected using simple X-ray films in the emergency department, which extended to almost all of the bodies, with a review of the literature.

Since Winslow and Edwards24) reviewed 20 cases of the arteriovenous fistulas involving temporal artery described in the world wide literatures up to 1934, several authors have added the cases sporadically, but the arteriovenous fistula of the superficial temporal artery is unusual to the head and neck surgeons. Recently we experienced one case of huge traumatic arteriovenous fistula involving the superficial temporal artery and present it here.

PURPOSE: Delirium is a common and worrisome problem among elder hospitalized patients. Many studies have sought to evaluate the risk factors of delirium. Most of these studies have dealt with the intensive care unit, with virtually nothing known about the emergency room. Our study was designated to evaluate the risk factors in an emergency department. METHODS: We retrospectively reviewed 414 cases of elder patients admitted to the general ward of internal medicine via the emergency room between January 2009 and December 2009. We divided these patients into a delirium group and non-delirium group. We statistically evaluated 31 known risk factors of delirium in these two groups. RESULTS: Using chi-square test, 14 of 31 known risk factors of delirium were proven as risk factors of delirium in an emergency room. Using logistic regression, three of the 14 proven risk factors were revealed as prior factors. CONCLUSION: A variety of factors of delirium are risk factors of delirium in an emergency room. A few important known risk factors are failed to pass statistically evaluation. These results are influenced by cultural pecularities of South Korea. Also, the small sample size limited conclusive evaluation. Nonetheless, the importance of patients' past medical history, laboratory results, and choice of medication when treating elder hospitalized patients to prevent delirium is likely important in reducing mortality and morbidity.

PURPOSE: Daegu, Korea was severely affected by pandemic and post-pandemic H1N1 infection during August 2009 to March 2012. The aim of this study was to analyze various clinical characteristics of patients who visited the emergency department with H1N1 infection during the first three years, and to compare the results for each year. We then performed an evaluation of the differences. METHODS: The medical records of patients who visited our emergency department and conformed to H1N1 virus infection by conventional rRT-PCR during the pandemic wave from August 2009 to March 2010(wave 1) and post-pandemic waves from August 2010 to March 2011(wave 2) and from August 2011 to March 2012(wave 3) were reviewed. A total of 986 patients (wave 1; 840, wave 2; 144, wave 3; 2) were included in this study. We analyzed the clinical characteristics, proportions of pneumonia, admission rate, relationships with underlying medical conditions, and requirement for mechanical ventilation of the infected patients, and then performed a statistical evaluation of the differences between wave 1 and wave 2 that was severely affected. RESULTS: During wave 1,840 patients, during wave 2, 144 patients, and during wave 3, two patients were diagnosed as novel influenza. Age 18-39 showed a significantly higher rate(78.7%) in the wave 1 patients group. Main clinical symptoms were cough and febrile sense in both waves. Patients with underlying medical conditions in wave 2(97 cases, 67.4%) showed a higher rate than those of wave 1(101 cases, 12.0%). Chronic obstructive pulmonary disorder was the most closely related underlying disorder in wave 2(18.8%). Patients requiring admission(37.5%) and ventilatory care(6.9%) due to severe pneumonic symptoms showed a significantly higher rate in wave 2. Only two young patients were diagnosed as novel influenza. Both complained of mild fever and cough, which recovered spontaneously. CONCLUSION: Most cases of influenza A (H1N1) infection were uncomplicated, characterized by influenza-like symptoms and spontaneous recovery. The number of patients showed a marked decreased year by year, however, the severity of clinical presentations increased in wave 2. Young adults who did not have cross-reactive antibodies to novel influenza A (H1N1) from previous infection or immunization were dominant in wave 1. Older patients with underlying medical conditions were more likely to admitted and present fatal progress in wave 1 and wave 2. Because influenza viruses are unpredictable, continued national preparedness, flexible response, and careful monitoring are essential.

OBJECTIVE: This study was designed to investigate the correlation between insertion depth of artificial disc and postoperative kyphotic deformity after Prodisc-C total disc replacement surgery, and the range of artificial disc insertion depth which is effective in preventing postoperative whole cervical or segmental kyphotic deformity. METHODS: A retrospective radiological analysis was performed in 50 patients who had undergone single level total disc replacement surgery. Records were reviewed to obtain demographic data. Preoperative and postoperative radiographs were assessed to determine C2-7 Cobb's angle and segmental angle and to investigate postoperative kyphotic deformity. A formula was introduced to calculate insertion depth of Prodisc-C artificial disc. Statistical analysis was performed to search the correlation between insertion depth of Prodisc-C artificial disc and postoperative kyphotic deformity, and to estimate insertion depth of Prodisc-C artificial disc to prevent postoperative kyphotic deformity. RESULTS: In this study no significant statistical correlation was observed between insertion depth of Prodisc-C artificial disc and postoperative kyphotic deformity regarding C2-7 Cobb's angle. Statistical correlation between insertion depth of Prodisc-C artificial disc and postoperative kyphotic deformity was observed regarding segmental angle (p<0.05). It failed to estimate proper insertion depth of Prodisc-C artificial disc effective in preventing postoperative kyphotic deformity. CONCLUSION: Postoperative segmental kyphotic deformity is associated with insertion depth of Prodisc-C artificial disc. Anterior located artificial disc leads to lordotic segmental angle and posterior located artificial disc leads to kyphotic segmental angle postoperatively. But C2-7 Cobb's angle is not affected by artificial disc location after the surgery.

OBJECTIVE: This study was conducted to evaluate scorecards for early recognition of high-risk patients of delirium in the emergency department (ED). METHODS: Data from 399 consecutive patients aged 65 years or older between January 1, 2015 and December 31, 2015 were retrospectively analyzed. Delirium was identified by reviewing medical records and was confirmed by a psychiatrist. The study population was divided into a training and validation group. Predisposing factors were evaluated and validated by multivariate logistic regression analysis and a calibration plot, after which a scorecard was constructed using these factors and applying points to double odds to each regression coefficient. RESULTS: Dementia, transfer from a long-term care facility, acute acid-base imbalance, moderate pain, and stroke were independent predisposing factors for delirium in ED, with assigned scores in the scorecard of 3, 2, 2, 2, and 2, respectively. The total score of the scorecard for delirious patients was significantly higher than that for non-delirious patients in both the training and validation groups. The coefficient of determination (R²) of the calibration plot was 0.74 and 0.68 in the training and validation group, respectively. In the receiver operation characteristic curve, the cut-off point of the scorecard for delirium was 2.5 and the sensitivity, specificity, and accuracy were 75.0%, 87.8%, and 86.7% in training group, while they were 76.9%, 85.1%, and 84.2% in the validation group, respectively. CONCLUSION: The scorecard was a useful screening tool for early recognition of patients with a high-risk of developing delirium in the ED.

Patients with inflammatory bowel disease who fail to respond to first-line agents such as 5-ASA compounds and corticosteroids can benefit from immunomodulating medications. In past years, the short-term effectiveness of CsA in Inflammatory bowel disease(IBD) has been reported, but the long-term efficacy, benefit, and safety of this therapy have not been fully established yet. This study was conducted using a total of 60 IBD patients with long-term follow-up from among the 82 patients who visited the IBD Clinic, Song Do Hospital, Seoul, ROK, from Jan. 1994 to Dec. 1996. The effectiveness of CsA was analyzed with respect to induction and maintenance of the remission in the 43 patients with ulcerative colitis(UC) and 17 the patients with Crohn's disease(CD). Treatment on admission was with intravenous CsA (4mg/kg/day) for 7-10 days in 15 patients with UC and in 13 patients with CD. These 28 patients were unresponsive to conventional treatment and had a recurrence of symptoms on refractory to first-line agents. Following the intravenous induction of cyclosporine, the patients continued to receive oral CsA (2.0-5.0mg/Bd.wt/day). In another group, 28 patients with UC and 4 patients with CD who were nonresponsive to or had recurrence of symptoms with first-line agents were treated with oral CsA. The mean period of treatment with CsA was an average of 10 months for CD and 7.5 months for UC. The CsA blood levels were measured by whole blood monoclonal radioimmunoassay, and levels of 200-400 ng per milliliter were obtained. Among the 43 patients with UC, 33 patients had remission (77%) within a mean induction time of 3.2 months and maintained remission for a mean of 7.1 months. Of the 15 patients with UC who had been admitted for CsA IV therapy, all the patients had remission within a mean of 2.8 months and maintained remission for 6.5 months. Among the 17 patients with CD, 9 patients had remission (52.1%) within a mean of 2.7 months and remained in remission for a mean of 8.6 months. Of the 13 patients with CD who had been admitted for CsA IV therapy, 7 patients (53.8%) had remission within a mean of 2.6 months and maintained remission for a mean of 8.0 months. During the management with an average medium dosage of CsA, no serious side effects or toxicity was observed. In this study, initial cyclosporine IV (4mg/kg/day) therapy, followed by PO (2-5mg/kg/day) therapy was effective in achieving remission in ulcerative colitis but not in Crohn's disease, and the initial continuous intravenous infusion of CsA induced a more rapid and prolonged remission than oral CsA. During the induction and maintenance of remission, serious side effects were not found during the period of this study. In cases of acute or severe and refractory inflammatory bowel disease or of recurrence after conventional therapy, the continuous intravenous infusion of CsA for 7-10 days will induce a more rapid and prolonged remission than the oral administration of CsA.
